DETAILED DESCRIPTION OF THE DRAWINGS
[0338] A connecting device designated as a whole by 100 serves, for
example, for connecting a first substantially plate-like part 102
to a second likewise substantially plate-like part 104 (see FIGS. 1
to 4).
[0339] The two parts 102 and 104 consist of wood or plywood for
example, but could consist of any other materials such as a
metallic material or a plastic material (e.g. Plexiglas) for
example. Furthermore, provision may be made for the first part 102
and the second part 104 to consist of mutually different
materials.
[0340] In the connected state of the two parts 102 and 104, a
contact surface 106 of the first part 102 which forms a narrow side
of the first part 102 abuts on a contact surface 108 of the second
part 104 which forms a major face of the second part 104.
[0341] A respective groove 110, which is formed in the related part
102 or 104, opens out into each of the contact surfaces 106, 108
and comprises a base section 112 in the form of a segment of a
circular cylinder or a section of a circular cylinder and two
undercut sections 114 which extend away from the base section 112
in a thickness direction 116.
[0342] The radius of curvature of the base section 112 is larger
than the groove depth T (see FIG. 4) so that the arched bottom
surface of the groove 118 intersects the respective contact surface
106, 108 at an acute angle.
[0343] The base section 112 of the groove 110 has a width B of
approximately 8 mm for example in the thickness direction 116.
[0344] Each of the undercut sections 114 of the groove 110 is
bounded on the side thereof remote from the respective contact
surface 106 and 108 by a bottom surface 120 which is flush with the
bottom surface of the groove 118 and is in the form of a section of
the surface of a circular cylinder and has the same radius of
curvature as the bottom surface of the groove 118 of the base
section 112.
[0345] In the direction toward the contact surface 106 or 108, each
undercut section 114 is bounded by an undercut surface 122 which is
likewise in the form of a section of the surface of a circular
cylinder and is concentric with the bottom surface 120 and has a
smaller radius of curvature.
[0346] Each of the undercut sections 114 is bounded laterally by a
lateral boundary surface 124 which runs perpendicularly to the
respective contact surface 106 and 108.
[0347] The width b, i.e. the extent thereof in the thickness
direction 116, amounts to approximately 1 mm for example for each
of the undercut sections 114.
[0348] The height h, i.e. the distance between the bottom surface
120 and the undercut surface 122, amounts to approximately 2 mm for
example for each of the undercut sections 114.
[0349] The base section 112 of each groove 110 is bounded by
lateral boundary walls 126 which run substantially perpendicularly
to the respective contact surface 106 and 108 and they are spaced
from each other by the groove width B.
[0350] As can be seen from FIG. 3 for example, a substantially
cylindrical access opening 128 and in particular an access boring
running perpendicularly to one of the lateral boundary walls 126
opens out into the groove 110 of the first part 102 and the other
end thereof opens out into a major face 129 of the first part 102
and thereby enables access to be made to the base section 112 of
the groove 110 from an area outside the first part 102.
[0351] In order to produce the previously described grooves 110 in
the parts 102 and 104, the groove milling device described in EP 1
990 549 A1 for example can be used.
[0352] For the purposes of connecting the parts 102, 104 to one
another, one or more grooves 110 and in particular grooves 110 of
the type described hereinabove can be provided in each of the parts
102, 104.
[0353] However, provision could also be made for just one of the
parts 102, 104 to be provided with one or more grooves 110 and in
particular grooves 110 of the previously mentioned type, whereas
the further part 104, 102 has no groove 110 of the previously
described type, or has a differently formed groove 110, one or more
borings, one or more recesses, one or more projections and/or one
or more cut-outs, or is in its original state.
[0354] Various embodiments of connecting devices 100 for connecting
different parts 102, 104 and in particular differently prepared
parts 102, 104, are described in the following.
[0355] A first embodiment of a connecting device 100 that is
illustrated in FIGS. 5 to 9 comprises a connecting element 130
which is insertable into a groove 110 and a connecting element 130
which is in the form of a screw element 132.
[0356] A connecting element 130 which is insertable into a groove
110 is preferably to be understood as being a connecting element
130 that is insertable into a groove 110 which comprises a base
section 112 and one or more undercut sections 114 that extend away
from the base section 112 in a thickness direction 116. The one
undercut section 114 or the plurality of undercut sections 114
preferably comprise one or more undercut surfaces 122 which are
formed and arranged concentrically to the base section 112. In
particular hereby, the undercut surface 122 or the undercut
surfaces 122 is or are in the form of a section of the surface of a
circular cylinder.
[0357] A connecting element 130 that is insertable into a groove
110 preferably comprises a main body 134 which comprises a main
body part 136 corresponding to the base section 112 of the groove
110 and one or more retaining projections 138 corresponding to the
undercut sections 114.
[0358] The retaining projections 138 each have a curved supporting
surface 140 which is in the form of an arc of a circle in
longitudinal section.
[0359] In particular, the retaining projections 138 are formed such
as to be non-self-cutting.
[0360] In this description and the accompanying Claims, a
longitudinal section, a longitudinal direction, etc. is to be
understood as a section or a movement of the connecting element 130
in a plane in which a path of movement of the connecting element
130 lies when it is being pushed into a groove 110.
[0361] In particular, a longitudinal section is a section taken
perpendicularly with respect to an axis of symmetry of the
supporting surfaces 140 of the connecting element 130.
[0362] A cross section is to be understood in particular, as a
section taken perpendicularly with respect to a longitudinal
section, for example, a section taken perpendicularly with respect
to a contact surface 106, 108 and parallel to the axis of symmetry
of the supporting surfaces 140 of the connecting element 130.
[0363] Preferably, a cross section is a section along a plane in
which the axis of symmetry of the supporting surfaces 140 of the
connecting element 130 extends.
[0364] In the first embodiment of the connecting device 100 that is
illustrated in FIGS. 5 to 9, the connecting element 130 which is
insertable into a groove 110 comprises a retaining element 142 that
is arranged on the main body 134 and in particular a retaining
element that is mounted thereon in rotatable manner.
[0365] In particular, the retaining element 142 is arranged on the
main body 134 such as to be rotatable about a rotational axis 144
running parallel to the thickness direction 116.
[0366] As can be perceived from FIG. 8 in particular, the retaining
element 142 comprises two engagement projections 146 which are
arc-shaped and arranged eccentrically of the rotational axis
144.
[0367] In particular, an engagement section 148 of the connecting
element 130 in the form of a screw element 132 is engageable by
means of the engagement projections 146 and is able to be drawn
thereby towards the rotational axis 144.
[0368] The connecting element 130 in the form of a screw element
132 also comprises a stop 150 beside the engagement section
148.
[0369] The screw element 132 is fixable to one of the parts 102,
104 in a correct position in a reliable manner by means of the stop
150.
[0370] In particular, it can be ensured by means of the stop 150
that, in the installed state of the screw element 132 on one of the
parts 102, 104, the engagement section 148 protrudes sufficiently
far above a contact surface 106, 108 of the part 102, 104 as to be
brought into engagement with the retaining element 142.
[0371] In the installed state of the connecting element 130 that is
insertable into the groove 110, the contact surfaces 106, 108 of
the part 102, 104 and a bearing surface 152 of the connecting
element 130 are preferably substantially flush.
[0372] The connecting element 130 is preferably screwable to the
part 102, 104 in which the groove 110 is arranged. To this end, the
main body 134 of the connecting element 130 comprises two through
openings 154 that serve for the purposes of feeding (not
illustrated) screws therethrough. In addition, the through openings
154 are provided with recesses 156 in order to enable (not
illustrated) screw heads to be accommodated within an outer contour
of the main body 134.
[0373] The connection between the parts 102, 104 by means of the
connecting device 100 is established as follows:
[0374] Firstly, the connecting element 130 in the form of a screw
element 132 is screwed into one of the parts 102, 104 until the
stop 150 of the screw element 132 abuts on the contact surface 106,
108.
[0375] The further part 104, 102 is then provided with a groove 110
and in particular with one of the grooves 110 illustrated in FIGS.
1 to 4.
[0376] Thereupon, the connecting element 130 that is insertable
into the groove 110 is inserted into the groove 110 and fixed to
the part 102, 104 by means of the (not illustrated) screws.
[0377] In the installed state of the connecting element 130 that is
insertable into the groove 110, the retaining element 142 is
accessible through a cylindrical access boring 128 which was
previously produced in the part 102, 104.
[0378] In a next step, the parts 102, 104 are laid on one another
in such a way that the engagement section 148 of the screw element
132 enters a seating opening 158 corresponding thereto in the main
body 134 of the connecting element 130.
[0379] The parts 102, 104 then abut one another at their contact
surfaces 106, 108.
[0380] For the purposes of fixing the parts 102, 104 relative to
each other, the retaining element 142 then only has to be moved
from the initially set release position into a retaining
position.
[0381] To this end, a (not illustrated) wrench is brought into
engagement with a wrench seating 160 of the retaining element 142
through the access boring 128. The retaining element 142 is then
moved from the release position into the retaining position by
rotating the wrench and thus too the retaining element 142 about
the rotational axis 144.
[0382] The engagement projections 146 thereby engage behind the
engagement section 148 of the screw element 132 and draw it towards
the rotational axis 144.
[0383] A pulling effect is thereby exerted on the parts 102, 104 so
that they are firmly connected to one another.
[0384] The connecting element 130 in the form of a screw element
132 preferably has a substantially rotationally symmetrical
engagement section 148. In this way, the screw element 132 can
always be gripped reliably by means of the retaining element 142
independently of the rotational orientation.
[0385] The anchoring of the connecting element 130 which comprises
the engagement section 148 can be effected on the one hand by means
of the illustrated screw. However, as an alternative thereto,
bolt-like pressure, an adhesive, screwing-in by means of a Spax
thread or a metric thread, fixing by means of a dowel pin, riveting
and/or welding an element which comprises the engagement section
148 could also be envisaged for the process of fixing to the one
part 102, 104.
[0386] A second embodiment of a connecting device 100 that is
illustrated in FIGS. 10 to 15 differs from the first embodiment
illustrated in FIGS. 5 to 9 substantially in that a substantially
parallelepipedal connecting element 130 is provided in addition to
a connecting element 130 that is insertable into a groove 110.
[0387] In particular, this parallelepipedal connecting element 130
is screwable onto a contact surface 108 of a part 104 by means of
two screws 162.
[0388] The parallelepipedal connecting element 130 comprises two
engagement projections 146 and a substantially semi-circular
engagement channel 164.
[0389] The connecting element 130 that is introducible into the
groove 110 comprises a retaining element 142 which has an at least
partly substantially T-shaped cross section and thus comprises an
engagement section 148.
[0390] In particular, the retaining element 142 is introducible
into the engagement channel 164 of the parallelepipedal connecting
element 130 and is adapted to be brought into engagement therewith
by means of the engagement projections 146 by a rotary
movement.
[0391] Furthermore, the connecting element 130 that is introducible
into the groove 110 comprises two plug-in projections 166 which are
insertable into seating pockets 168 corresponding thereto in the
parallelepipedal connecting element 130.
[0392] The plug-in projections 166 and the seating pockets 168
preferably have a ribbed or undulating surface in order to prevent
a displacement of the plug-in projections 166 within the seating
pockets 168.
[0393] As can be perceived from FIGS. 11 and 14 in particular, the
connecting element 130 that is arrangeable in the groove 110 is
preferably arrangeable entirely in the groove 110.
[0394] The bearing surface 152 of the main body 134 of the
connecting element 130 is set back relative to the contact surface
106 of the part 102 in the installed state of the connecting
element 130 in the groove 110.
[0395] The contact surfaces 106, 108 thereof abut each other in the
connected state of the parts 102, 104
[0396] The parallelepipedal connecting element 130 that is screwed
tightly to the contact surface 108 of the second part 104 then
extends into the groove 110 in the first part 102.
[0397] Reliable fixing of the parts 102, 104 relative to each other
with reference to the thickness direction 116 can thus be obtained
merely by pushing the parallelepipedal connecting element 130 into
the groove 110 in the first part 102.
[0398] By rotating the retaining element 142 by means of the (not
illustrated) wrench, the retaining element 142 can be brought into
the retaining position in which the engagement section 148 engages
behind the engagement projections 146 and the connecting elements
130 as well as the parts 102, 104 define a direction of connection
170 that is oriented perpendicularly to the contact surfaces 106,
108.
[0399] In all other respects, the second embodiment of the
connecting device 100 that is illustrated in FIGS. 10 to 15
coincides in regard to the construction and functioning thereof
with the first embodiment illustrated in FIGS. 5 to 9 so that, to
that extent, reference is made to the preceding description
thereof.
[0400] A third embodiment of a connecting device 100 that is
illustrated in FIGS. 16 and 17 differs from the second embodiment
illustrated in FIGS. 10 to 15 substantially in that a connecting
element 130 in the form of a screw element 132 is provided in
addition to a connecting element 130 that is insertable into the
groove 110
[0401] This screw element 132 is screwable into one of the parts
102, 104.
[0402] A parallelepipedal section 172 of the screw element 132
comprises an engagement channel 164 and two engagement projections
146.
[0403] Thus, in a similar way to the second embodiment illustrated
in FIGS. 10 to 15, the third embodiment that is illustrated in
FIGS. 16 and 17 is also provided with a connecting element 130
which is positionable on and in particular screwable to a contact
surface 106, 108 of a part 102, 104 into which there is
introducible a retaining element 142, which has a substantially
T-shaped cross section and thus comprises an engagement section
148.
[0404] In all other respects, the third embodiment of the
connecting device 100 that is illustrated in FIGS. 16 and 17
coincides in regard to the construction and functioning thereof
with the second embodiment illustrated in FIGS. 10 to 15 so that,
to that extent, reference is made to the preceding description
thereof.
[0405] A fourth embodiment of a connecting device 100 that is
illustrated in FIGS. 18 to 22 differs from the first embodiment
illustrated in FIGS. 5 to 9 substantially in that two connecting
elements 130 that are insertable into a groove 110 are associated
with each of the parts 102, 104.
[0406] Hereby, the grooves 110 in each part 102, 104 are arranged
to overlap so that the bottom surfaces 118 of the grooves 110
intersect or border one another within the respective part 102, 104
underneath the contact surface 106, 108.
[0407] In the fourth embodiment of the connecting device 100 that
is illustrated in FIGS. 18 to 22, two types of connecting elements
130 are provided.
[0408] On the one hand, there are provided connecting elements 130
each of which comprises two suspension elements 174.
[0409] Furthermore, there are provided connecting elements 130
which each comprise two suspension element seatings 176.
[0410] Both the suspension elements 174 and the suspension element
seatings 176 each comprise at least one inclined surface 178 which
is inclined to the bearing surface 152 and/or inclined to the
contact surface 106, 108.
[0411] Furthermore, all of the connecting elements 130 comprise a
respective securing projection 180 and a securing seating 182.
[0412] A securing device 184 is formed by means of the securing
projection 180 and the securing seating 182. The securing device
184 serves, in particular, for fixing at least one of the
connecting elements 130 in the groove 110 and in particular for
preventing unwanted displacement of the connecting element 130
within the groove 110.
[0413] To this end, a securing projection 180 of a connecting
element 130 is moveable into engagement with a securing seating 182
of a further connecting element 130 (see in particular, FIGS. 21
and 22).
[0414] A securing projection 180 and a securing seating 182 of a
connecting element 130 are preferably arranged at mutually opposite
end regions 186 of the main body 134 and in particular, the
supporting surfaces 140.
[0415] As can be perceived from FIG. 19 in particular, the
connecting elements 130 further comprise a respective through
opening 188 which is arranged in the respective connecting element
130 in such a manner that the through openings 188 of two
interconnected connecting elements 130 are aligned with one another
in the connected state of the parts 102, 104.
[0416] By introducing a securing element and in particular a
securing pin into the through openings 188, the connecting elements
130 and thus too the parts 102, 104 can be secured from unwanted
displacement thereof relative to each other.
[0417] As can be perceived from FIG. 19 in particular, the
connection of the parts 102, 104 by means of the connecting
elements 130 is not effected in the fourth embodiment of the
connecting device 100 that is illustrated in FIGS. 18 to 22 by
rotation of a retaining element 142. Rathermore, the parts 102, 104
together with the connecting elements 130 arranged thereon are
initially moved towards one another in order to insert the
suspension elements 174 into the suspension element seatings 176
(see FIG. 18).
[0418] Thereafter, the parts 102, 104 and the connecting elements
130 arranged therein are displaced in parallel with the contact
surfaces 106, 108. The inclined surfaces 178 of the suspension
elements 174 and the suspension element seatings 176 thereby come
into engagement with one another so that the connecting elements
130 and thus too the parts 102, 104 are pulled towards one
another.
[0419] The fourth embodiment of the connecting device 100 that is
illustrated in FIGS. 18 to 22 is suitable, in particular, for
connecting the framework parts of a bedstead.
[0420] In all other respects, the embodiment of a connecting device
100 that is illustrated in FIGS. 18 to 22 coincides in regard to
the construction and functioning thereof with the first embodiment
illustrated in FIGS. 5 to 9 so that, to that extent, reference is
made to the preceding description thereof.
[0421] A fifth embodiment of a connecting device 100 that is
illustrated in FIGS. 23 to 26 differs from the first embodiment
illustrated in FIGS. 5 to 9 substantially in that two connecting
elements 130 that are insertable into a respective groove 110 are
provided.
[0422] In addition in the case of the embodiment of the connecting
device 100 that is illustrated in FIGS. 23 to 26, provision is made
for a retaining element 142 to be operable by means of a magnet
element 190 in order to move the retaining element 142 from a
release position into a retaining position and/or from the
retaining position into the release position.
[0423] In particular, the magnet element 190 is an element that is
operable magnetically by means of a (not illustrated) magnet
device.
[0424] The magnet element 190 is movable linearly to and fro by
means of the magnet device for example.
[0425] The retaining element 142 preferably comprises a seating 192
for the magnet element 190.
[0426] One of the connecting elements 130 preferably serves for
accommodating the retaining element 142 together with the magnet
element 190 that is accommodated therein.
[0427] To this end in particular, this connecting element 130
comprises a substantially slot-like guide 194 in the main body
134.
[0428] The retaining element 142 is movable along the slot-like
guide 194 relative to the main body 134.
[0429] Furthermore, the retaining element 142 has two inclined
surfaces 178 which are moveable into engagement with engagement
projections 146 in the further connecting element 130.
[0430] The inclined surfaces 178 of the retaining element 142 thus
form an engagement section 148 of the retaining element 142.
[0431] As can be perceived from FIGS. 24 and 25 in particular, the
connecting elements 130 in accordance with the fifth embodiment of
the connecting device 100 that is illustrated in FIGS. 23 to 26
comprise plug-in projections 166 and seating pockets 168.
[0432] When connecting the connecting elements 130 to one another,
the plug-in projections 166 are firstly inserted into the seating
pockets 168.
[0433] The engagement section 148, in particular the inclined
surfaces 178, is moved simultaneously behind the engagement
projections 146 with reference to the direction of connection
170.
[0434] Finally, the bearing surfaces 152 of the connecting elements
130 as well as the contact surfaces 106, 108 of the parts 102, 104
come to abut on one another.
[0435] In a next step, the magnet element 190 is then actuated for
fixing the connecting elements 130 and hence the parts 102, 104
relative to each other along the direction of connection 170.
[0436] To this end, the magnet device is brought into the proximity
of the connecting device 100 and the magnet element 190 is
accelerated within the seating 192.
[0437] The magnet element 190 is thereby accelerated, in
particular, repeatedly, within the seating 192 and is braked by
striking an end region of the seating 192.
[0438] Hereby, the seating 192 is bounded at one end by a locking
surface 196 and at the other end by an unlocking surface 198.
[0439] The retaining element 142 is brought into the retaining
position in which the engagement section 148 of the retaining
element 142 engages behind the engagement projections 146 due to an
impact of the magnet element 190 on the locking surface 196.
[0440] The retaining element 142 is moved in the opposite direction
and hence the engagement section 148 is disengaged from the
engagement projections 146 due to the magnet element 190 striking
the unlocking surface 198.
[0441] The retaining element 142 can thus be moved selectively into
the retaining position or into the release position.
[0442] A displacement of the main bodies 134 of the connecting
elements 130 relative to each other due to the magnet element 190
striking the locking surface 196 or the unlocking surface 198 is
preferably prevented by means of the plug-in projections 166 and
the seating pockets 168.
[0443] The fifth embodiment of the connecting device 100 that is
illustrated in FIGS. 23 to 26 can, in particular, offer the
advantage that the parts 102, 104 can be connected to one another
without any form of visual impairment. In particular, one can
dispense with an access boring 128.
[0444] In all other respects, the fifth embodiment of the
connecting device 100 that is illustrated in FIGS. 23 to 26
coincides in regard to the construction and functioning thereof
with the first embodiment illustrated in FIGS. 5 to 9 so that, to
that extent, reference is made to the preceding description
thereof.
[0445] A sixth embodiment of a connecting device 100 that is
illustrated in FIGS. 27 and 28 differs from the fifth embodiment
illustrated in FIGS. 23 to 26 substantially in that the retaining
element 142 is a retaining element 142 in the form of a screw.
[0446] The magnet element 190 is drivable in rotary manner by means
of the magnet device in order to specifically actuate the retaining
element 142.
[0447] The retaining element 142 and the magnet element 190 are
arranged on a main body 134 of a connecting element 130 that is
introducible into a groove 110.
[0448] A further connecting element 130 which is likewise
preferably introducible into a groove 110 preferably comprises a
seating 200 for the retaining element 142 in the form of a
screw.
[0449] In particular, the seating 200 is a threaded nut.
[0450] The seating 200 is preferably arranged such as to be
moveable, particularly in spring-like manner, on a main body 134 of
the further connecting element 130. To this end in particular, two
spring elements 202 are provided on the main body 134.
[0451] The main bodies 134 of the connecting elements 130
preferably comprise a respective cover element 204 by means of
which an interior space 206 of the respective main body 134 is
closable.
[0452] In particular, the seating 200, the magnet element 190
and/or the retaining element 142 in the form of a screw are
accessible and/or removable from the respective main body 134 by
removing the respective cover element 204.
[0453] As can be perceived from FIG. 27 in particular, the
connecting elements 130 preferably further comprise at least one
projection 208, a recess 210 corresponding thereto and/or at least
one ridge 212 and/or a groove 214 corresponding thereto for
aligning the connecting elements 130 relative to each other in all
of the directions running perpendicularly to the direction of
connection 170.
[0454] In regard to the type of actuation of the retaining element
142 by means of the magnet element 190 as well as in regard to the
actuation of the magnet element 190 by means of the magnet device,
reference is made to WO 99/43961 A1 the contents of which are
hereby incorporated by reference in this description.
[0455] In all other respects, the sixth embodiment of the
connecting device 100 that is illustrated in FIGS. 27 and 28
coincides in regard to the construction and functioning thereof
with the fifth embodiment illustrated in FIGS. 23 to 26 so that, to
that extent, reference is made to the preceding description
thereof.
[0456] A seventh embodiment of a connecting device 100 that is
illustrated in FIGS. 29 and 30 differs from the fifth embodiment
illustrated in FIGS. 23 to 26 substantially in that the connecting
elements are connectible to one another 130 by means of spring
elements 216.
[0457] To this end in particular, the spring elements 216 can
engage behind engagement projections 146.
[0458] The spring elements 216 and the engagement projections 146
are arranged on mutually differing connecting elements 130.
[0459] In the seventh embodiment of the connecting device 100 that
is illustrated in FIGS. 29 and 30, there is provided a storage
device 218 by means of which the retaining energy or retaining
force necessary for the retention of the connecting elements 130 is
storable.
[0460] The storage device 218 comprises two storage elements 220
which are formed, in particular, by the spring elements 216 and a
blocking element 222.
[0461] The spring elements 216 can be held in a biased position by
means of the blocking element 222 (see FIG. 29).
[0462] In the embodiment of the connecting device 100 that is
illustrated in FIGS. 29 and 30, the retaining energy and/or
retaining force that is necessary for holding the connecting
elements 130 and thus the parts 102, 104 together can be applied
before actually connecting the parts 102, 104 to one another.
[0463] When connecting the connecting elements 130 arranged on the
parts 102, 104 together, the blocking element 222 is preferably
moved by means of at least one engagement projection 146 from the
blocking position illustrated in FIG. 29 into the release position
illustrated in FIG. 30.
[0464] In consequence, the spring elements 216 can move towards one
another and engage behind the engagement projections 146.
[0465] In particular, the connecting device 100 that is illustrated
in FIGS. 29 and 30 is a concealed, self-tensioning connecting
device 100.
[0466] The storage device 218 can preferably be loaded before
installing, during the installation process or after installing the
connecting elements 130 in the parts 102, 104. In particular, the
blocking element 222 can be moved into the blocking position
illustrated in FIG. 29 at any point in time before the connection
of the parts 102, 104 to one another.
[0467] In all other respects, the seventh embodiment of the
connecting device 100 that is illustrated in FIGS. 29 and 30
coincides in regard to the construction and functioning thereof
with the fifth embodiment illustrated in FIGS. 23 to 26 so that, to
that extent, reference is made to the preceding description
thereof.
[0468] An eighth embodiment of a connecting device 100 that is
illustrated in FIG. 31 differs from the seventh embodiment
illustrated in FIGS. 29 and 30 substantially in that the spring
element 216 does not directly engage with an engagement projection
146, but rather, it actuates an engagement section 148 of a
substantially linearly movable retaining element 142.
[0469] In the eighth embodiment of the connecting device 100 that
is illustrated in FIG. 31, the storage device 218 can preferably
also be loaded by tensioning the spring element 216, for example,
by holding the retaining element 142 and/or the spring element 216
in a biased position.
[0470] When connecting and/or due to the connection of the parts
102, 104 to one another, the stored force and/or energy are
preferably released in order to fix the connecting elements 130
relative to each other, in particular, by the inter-engagement of
the engagement section 148 of the retaining element 142 and the
engagement projections 146.
[0471] In all other respects, the eighth embodiment of the
connecting device 100 that is illustrated in FIG. 31 coincides in
regard to the construction and functioning thereof with the seventh
embodiment illustrated in FIGS. 29 and 30 so that, to that extent,
reference is made to the preceding description thereof.
[0472] A ninth embodiment of a connecting device 100 that is
illustrated in FIGS. 32 to 34 differs from the fifth embodiment of
a connecting device 100 illustrated in FIGS. 23 to 26 substantially
in that the connecting elements 130 which are connecting elements
130 that are insertible into a groove 110 comprise a
tongue-and-groove device 224.
[0473] In particular, the tongue-and-groove device 224 is formed by
a groove part 226 and a tongue part 228.
[0474] Here, the groove part 226 and the tongue part 228 are
arranged and/or formed on mutually differing connecting elements
130.
[0475] As can be perceived from FIGS. 32 and 33 in particular, the
connecting elements 130, in particular, the groove part 226 and the
tongue part 228, are moveable into engagement with one another by
inserting and pivoting the connecting elements 130 and/or the parts
102, 104 relative to each other.
[0476] The tongue-and-groove device 224 thereby serves, in
particular, for adhesive-free anchoring of the one part 102 on the
other part 104.
[0477] Hereby, the tongue-and-groove device 224 preferably
functions in a similar manner to the interlocking process for the
flooring elements of a click-together parquet flooring or a
click-together laminate flooring.
[0478] The ninth embodiment of a connecting device 100 that is
illustrated in FIGS. 32 to 34 is suitable, in particular, for the
connection of drawer fronts to drawers.
[0479] In all other respects, the ninth embodiment of the
connecting device 100 that is illustrated in FIGS. 32 to 34
coincides in regard to the construction and functioning thereof
with the fifth embodiment illustrated in FIGS. 23 to 26 so that, to
that extent, reference is made to the preceding description
thereof.
[0480] A tenth embodiment of a connecting device 100 that is
illustrated in FIGS. 35 to 37 differs from the first embodiment
illustrated in FIGS. 5 to 9 substantially in that there is provided
a connecting element 130 that is insertable into a groove 110 which
comprises one or more screw seatings 230.
[0481] Connecting elements 130 in the form of screw elements 132
are fixable in positive-locking and/or force-locking manner in the
screw seatings 230 in releasable manner.
[0482] For the purposes of anchoring the connecting element 130 in
the part 102 in which the groove 110 is arranged, the connecting
element 130 comprises a through opening 154 corresponding to that
in the first embodiment of the connecting device 100 that is
illustrated in FIGS. 5 to 9. The connecting element 130 is thus
fixable to the first part 102, in particular, by means of a (not
illustrated) screw 162 (see FIG. 13 for example).
[0483] In the tenth embodiment of the connecting device 100 that is
illustrated in FIGS. 35 to 37, the connecting elements 130 in the
form of screw elements 132 are passable through through openings
232 in the second part 104.
[0484] The connecting element 130 that is insertable into the
groove 110 and in particular the screw seatings 230 are thus
accessible from a side 234 of the second part 104 that is remote
from the first part 102.
[0485] The second part 104 can thus be clamped and/or mounted
firmly between the screw heads 236 of the screw elements 132 and
the connecting element 130 that is insertable into the groove by
screwing the screw elements 132 to the connecting element 130 that
is insertable into the groove 110.
[0486] The screw seatings 230 are threaded borings or elongate
holes with an internal thread for example. As an alternative
thereto, provision may be made for the screw seatings 230 to be
yielding seatings for self-tapping screws.
[0487] The screw seatings 230 for the self-tapping screws are
preferably seatings in the form of elongate holes.
[0488] The tenth embodiment of the connecting device 100 that is
illustrated in FIGS. 35 to 37 is suitable, in particular, for use
as an attachment anchor in thin-walled, easily-torn materials, for
example, in a similar manner to a dowel plug for fixing screws.
[0489] In all other respects, the tenth embodiment of a connecting
device 100 that is illustrated in FIGS. 35 to 37 coincides in
regard to the construction and functioning thereof with the first
embodiment illustrated in FIGS. 5 to 9 so that, to that extent,
reference is made to the preceding description thereof.
[0490] An eleventh embodiment of a connecting device 100 that is
illustrated in FIGS. 38 and 39 differs from the previously
described embodiments substantially in that the connecting device
100 also permits a relative movement of the parts 102, 104 relative
to each other in the installed and connected state of the parts
102, 104 and the connecting device 100.
[0491] Hereby, a guidance device 238 is formed by means of the
connecting device 100 and the parts 102, 104 are guided in movable
manner relative to each other by means of said guidance device.
[0492] Hereby, the connecting device 100 comprises at least one
connecting element 130 which is a connecting element 130 that is
insertable into a groove 110
[0493] This connecting element 130 preferably comprises a guidance
element 240, a guidance projection 242 for example which, in the
installed state of the connecting element 130, projects above the
bearing surface 152 of the main body 134 of the connecting element
130 and above the contact surface 106 of the part 102 in which the
connecting element 130 is arranged.
[0494] Here for example, the guidance element 240 is substantially
in the form of a parallelepiped.
[0495] The further part 104 preferably comprises a guidance groove
244 for accommodating the guidance element 240.
[0496] Hereby for example, the guidance groove 244 is integrated
into a connecting element 130 or into the part 104 itself.
[0497] In the eleventh embodiment of the connecting device 100 that
is illustrated in FIGS. 38 and 39, the guidance groove 244 is
formed in the part 104, in particular, in the form of a
substantially parallelepipedal recess in the side of the part 104
whereat the contact surface 108 is arranged.
[0498] As can be perceived from FIG. 39 in particular, unwanted
lateral displacement of the parts 102, 104 in a direction running
transverse to the direction of longitudinal extent of the guidance
groove 244 can be prevented in the installed state of the
connecting device 100 and the parts 102, 104.
[0499] A displacement of the parts 102, 104 relative to each other
along the direction of longitudinal extent of the guidance groove
244 is however still possible thereby.
[0500] The eleventh embodiment of the connecting device 100 that is
illustrated in FIGS. 38 and 39 is suitable, in particular, for use
as a sliding door fitting, for example, on the lower end of a
sliding door.
[0501] In all other respects, the eleventh embodiment of a
connecting device 100 that is illustrated in FIGS. 38 and 39
coincides in regard to the construction and functioning thereof
with the fourth embodiment illustrated in FIGS. 18 to 22 so that,
to that extent, reference is made to the preceding description
thereof.
[0502] A twelfth embodiment of a connecting device 100 that is
illustrated in FIGS. 40 and 41 differs from the eleventh embodiment
illustrated in FIGS. 38 and 39 substantially in that the guidance
element 240 comprises one or more bearing elements 246 for the
purposes of displaceable mounting of the parts 102, 104 relative to
each other.
[0503] In particular, the bearing elements 246 are in the form of
roller elements 248.
[0504] For example, two pairs of roller elements 248 are
provided.
[0505] In the twelfth embodiment of the connecting device 100 that
is illustrated in FIGS. 40 and 41, the guidance groove 244 is
formed by a connecting element 130 which is arranged in one of the
parts 102, 104.
[0506] Hereby, the guidance groove 244 preferably comprises a
guidance section 250 in which the guidance element 240 and in
particular the bearing elements 246 of the guidance element 240 can
engage behind the guidance groove 244.
[0507] With respect to the direction of the force of gravity g for
example, the guidance groove 244 is open downwardly so that the
connecting element 130 comprising the guidance element 240 together
with the part 102 on which the connecting element 130 is arranged
can be suspended in the guidance groove 244.
[0508] Such a connecting device 100 can then be used in particular,
as a suspension for a sliding door.
[0509] In all other respects, the twelfth embodiment of a
connecting device 100 that is illustrated in FIGS. 40 and 41
coincides in regard to the construction and functioning thereof
with the eleventh embodiment illustrated in FIGS. 38 and 39 so
that, to that extent, reference is made to the preceding
description thereof.
[0510] A thirteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 42 and 43 differs from the twelfth embodiment
illustrated in FIGS. 40 and 41 substantially in that a bearing
element 246 in the form of a roller element 248 is arranged on the
main body 134 of the connecting element 130.
[0511] This connecting element 130 too is preferably insertable
into a groove 110.
[0512] The bearing element 246 preferably projects above the
bearing surface 152 of the main body 134 and above a contact
surface 106 of the part 102 in which the connecting element 130 is
arranged.
[0513] In particular, the bearing element 246 in the form of a
roller element 248 is mounted on the main body 134 in rotary manner
and can roll on a running surface 252 for example.
[0514] The running surface 252 is, for example, arranged on a
further part 104 or is formed by the further part 104.
[0515] The running surface 252 can thus form a connecting element
130 of the connecting device 100 for example.
[0516] It can be advantageous for the running surface 252 to be
formed by a contact surface 108 of the further part 104.
[0517] In the installed state of the connecting device 100 and the
parts 102, 104, the bearing element 246 preferably abuts on the
running surface 252 and is movable along the running surface 252.
Consequently, the parts 102, 104 are also movable relative to each
other.
[0518] In all other respects, the thirteenth embodiment of a
connecting device 100 that is illustrated in FIGS. 42 and 43
coincides in regard to the construction and functioning thereof
with the twelfth embodiment illustrated in FIGS. 40 and 41 so that,
to that extent, reference is made to the preceding description
thereof.
[0519] A fourteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 44 to 46 differs from the fifth embodiment
illustrated in FIGS. 23 to 26 substantially in that the connection
of the connecting elements 130 to one another is producible by
means of a rotatable retaining element 142 corresponding to the
second embodiment that is illustrated in FIGS. 10 to 15.
[0520] In addition, no fixed plug-in projections 166 are provided
in the embodiment of the connecting device 100 that is illustrated
in FIGS. 44 to 46.
[0521] Rathermore, the connecting device 100 comprises a
positioning device 254 for positioning the parts 102, 104 and in
particular, the connecting elements 130 relative to each other.
[0522] The positioning device 254 comprises one or more positioning
elements 256 and one or more positioning element seatings 258.
[0523] The positioning elements 256 are preferably mounted in
moveable, yielding, resilient and/or spring-like manner.
[0524] In the embodiment of a connecting device 100 that is
illustrated in FIGS. 44 to 46, there are provided two positioning
elements 256 which are in the form of steel balls 260, each
positioning element being displaceable within a respective through
opening 262 and being arranged on one of the connecting elements
130.
[0525] In addition, a spring element 264 and a closure element 266
such as a set-screw 268 for example are arranged in each of the
through openings 262.
[0526] The at least one through opening 262 is tapered towards the
bearing surface 152 of the main body 134 so that one or more
retaining projections 270 are formed.
[0527] Unwanted escape of a positioning element 256 and in
particular a steel ball 260 from the through opening 262 can
preferably be prevented by means of the retaining projections
270.
[0528] Escape of the positioning element 256 at an end of the
through opening 262 opposite the bearing surface 152 is prevented
by means of the closure element 266.
[0529] The spring element 264 is arranged between the closure
element 266 and the positioning element 256. In this way, the
positioning element 256 is preferably holdable in a positioning
position in resilient yielding manner.
[0530] The positioning element 256 projects above the bearing
surface 152 in this positioning position.
[0531] One or more positioning element seatings 258 are preferably
formed such as to be at least partly complementary to the one or
the plurality of positioning elements 256. In particular, the
positioning element seatings 258 are formed such as to be
complementary to the sections of the positioning elements that
project above the bearing surface 152 256 in the positioning
position thereof.
[0532] Due to the resilient yielding mounting of the positioning
elements 256, they can be moved into the main body 134, in
particular, in order to enable the connecting elements 130 and the
parts 102, 104 to be displaced relative to each other whilst the
bearing surfaces 152 and/or the contact surfaces 106, 108 abut one
another.
[0533] As soon as the connecting elements 130 are arranged in a
desired position in which the positioning elements 256 are arranged
opposite the positioning element seatings 258, the positioning
elements 256 are moved automatically into the positioning element
seatings 258 by means of the spring elements 264.
[0534] Simple positioning of the parts 102, 104 relative to each
other can be effected in this way. In addition for example, the
parts 102, 104 can thereby be latched to one another in order to
facilitate the actuation of the retaining element 142 for the
purposes of stably connecting the parts 102, 104 to one
another.
[0535] In particular, provision may also be made for the connecting
device 100 to comprise exclusively a positioning device 254 but no
retaining element 142 for the purposes of bonding the parts 102,
104 to one another.
[0536] The fourteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 44 to 46 is suitable, in particular, for the
assembly of push-in shelves, partition walls, rear walls, cabinet
elements, etc.
[0537] Furthermore, the connecting device 100 can be used as a
bonding aid in places in which pressure cannot be applied and in
which pushing together or other processes of bringing two
connecting elements 130 into engagement with one another is
impossible.
[0538] In all other respects, the fourteenth embodiment of the
connecting device 100 that is illustrated in FIGS. 44 to 46
coincides in regard to the construction and functioning thereof
with the fifth embodiment illustrated in FIGS. 23 to 26 so that, to
that extent, reference is made to the preceding description
thereof.
[0539] A fifteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 47 to 49 differs from the ninth embodiment
illustrated in FIGS. 32 to 34 substantially in that the connecting
elements 130 and thus too the parts 102, 104 are connectible or are
connected to one another by means of a hinge element 272 of a hinge
device 274.
[0540] Hereby, two connecting elements 130 that are insertable into
a respective groove 110 in one of the parts of 102, 104 are
provided.
[0541] Each of the connecting elements 130 comprises two screw
seatings 230 for accommodating screws 162.
[0542] The hinge element 272 comprises two sections 276 that are
pivotal relative to each other.
[0543] Each of the sections 276 comprises two elongate holes 278
through which the screws 162 are passed and which are provided for
the purposes of fixing the respective section 276 to one of the
connecting elements 130.
[0544] Recesses 280 can be provided in the connecting elements 130
for simple and/or aesthetically appropriate mounting of the hinge
element 272 on the connecting elements 130.
[0545] In particular, protruding latches 282 of the sections 276 of
the hinge element 272 are receivable in these recesses 280.
[0546] The elongate holes 278 are preferably arranged and/or formed
in these latches 282.
[0547] The hinge element 272 can, for example, be a metallic part
or be formed from metallic parts.
[0548] As can be perceived from FIG. 49 in particular, the
connecting elements 130 and the parts 102, 104 are pivotal about a
pivotal axis 284 by means of the hinge element 272.
[0549] The fifteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 47 to 49 is suitable, in particular, for use
as a door hinge.
[0550] In all other respects, the fifteenth embodiment of a
connecting device 100 that is illustrated in FIGS. 47 to 49
coincides in regard to the construction and functioning thereof
with the ninth embodiment illustrated in FIGS. 32 to 34 so that, to
that extent, reference is made to the preceding description
thereof.
[0551] A sixteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 50 to 53 differs from the sixth embodiment
illustrated in FIGS. 27 and 28 substantially in that a locking
device is provided for connecting the two connecting elements 130
to one another in place of a screw connection.
[0552] To this end, the connecting device 100 comprises a movable
and in particular linearly displaceable locking bar element
286.
[0553] The locking bar element 286 is a component of a connecting
element 130 which is insertable into a groove 110 and which, in
addition to the main body 134 and the locking bar element 286,
comprises a drive shaft 288 and one or more magnet elements 190 for
driving the drive shaft 288.
[0554] As can be perceived from FIGS. 52 and 53 in particular, the
locking bar element 286 has an opening 292 which is substantially
parallelepipedal and comprises a toothed rack section 294 of a
rack-and-pinion device 296 on one side thereof.
[0555] In particular, the toothed rack section 294 is in engagement
with a pinion 298 of the rack-and-pinion device 296 which is
arranged on the drive shaft 288.
[0556] The magnet elements 190 are also arranged on the drive shaft
288 so that the drive shaft 288 is rotatable together with the
pinion 298 about a rotational axis 300 by means of the magnet
elements 190, in particular, by external contactless actuation by
means of a magnet device.
[0557] Due to the coupling of the pinion 298 to the toothed rack
section 294 of the locking bar element 286, the locking bar element
286 is linearly displaceable, in particular, along a locking
direction 302 by rotation of the drive shaft 288.
[0558] In particular, the locking direction 302 is substantially
perpendicular to the bearing surface 152 and/or to the contact
surface 106, 108 of at least one of the parts 102, 104.
[0559] The locking bar element 286 is accommodated or is
accommodable in linearly displaceable manner in a locking bar
element seating 304 of the main body 134 that is substantially
complementary thereto.
[0560] The drive shaft 288 together with the magnet elements 190
and the pinion 298 is receivable or is accommodated in a shaft
seating 306 of the main body 134 of the connecting element 130.
[0561] The locking bar element 286 is preferably movable along the
locking direction 302 into the main body 134 to such an extent that
the locking bar element 286 no longer projects above the bearing
surface 152 and/or the contact surface 106, 108 of at least one
part 102, 104.
[0562] In this position however, the locking bar element 286 may
nevertheless project above the main body 134 at an end of the
locking bar element seating 304 opposite the bearing surface 152 of
the main body 134.
[0563] Consequently, this position of the locking bar element 286
can only be realized if the main body 134 is of sufficiently large
dimensions as to accommodate the entire locking bar element 286 or
if the part 102, in which the connecting element 130 comprising the
locking bar element 286 is arranged, is provided with a recess 308
which adjoins the locking bar element seating 304 in the locking
direction 302 (see FIG. 51).
[0564] For the purposes of locking two parts 102, 104 together by
means of the connecting device 100, the locking bar element 286 is
moveable into the locking device position illustrated in FIGS. 50
and 51 for example wherein the locking bar element 286 projects
above the bearing surface 152 of the connecting element 130 and
above the contact surface 106 of the part 102.
[0565] Then for example, the locking bar element 286 extends into a
locking bar element seating 304 of a further connecting element 130
which is arranged in the further part 104. As an alternative or in
addition thereto, provision may be made for the further part 104 to
merely comprise a recess 308 for accommodating the locking bar
element 286.
[0566] For the purposes of optimizing the transmission of torque
from the magnet elements 190 to the drive shaft 288 and/or the
pinion 298, there is provided, in particular, a drive shaft 288
having a non-rotationally symmetrical cross section such as a
rectangular cross section for example. The magnet elements 190 and
the pinion 298 then preferably comprise seatings corresponding
thereto.
[0567] The drive shaft 288 can be a bar magnet for example.
[0568] Preferably, the magnet elements 190, the drive shaft 288,
the pinion 298 and/or the toothed rack section 294 of the locking
bar element 286 are dimensioned, formed and/or arranged in such a
way that the locking bar element 286 is moveable from a retaining
position into a release position, in particular, from a locking
position into a release position by a rotation of the drive shaft
288 through 180.degree..
[0569] The locking bar element 286 can then be moved into the
different desired positions in a particularly simple manner by
placing a magnet on different side surfaces of the part 102.
[0570] The sixteenth embodiment of the connecting device 100 that
is illustrated in FIGS. 50 to 53 is suitable, in particular, for
use as a furniture lock, as a shelf connector and/or for the
mounting of wall panels.
[0571] In all other respects, the sixteenth embodiment of the
connecting device 100 that is illustrated in FIGS. 50 to 53
coincides in regard to the construction and functioning thereof
with the sixth embodiment illustrated in FIGS. 27 and 28 so that,
to that extent, reference is made to the preceding description
thereof.
[0572] A seventeenth embodiment of a connecting device 100 that is
illustrated in FIG. 54 differs from the sixteenth embodiment
illustrated in FIGS. 50 to 53 substantially in that there are
provided two connecting elements 130 which each comprise at least
one magnet element 190.
[0573] Hereby for example, the magnet element 190 can be entirely
integrated into the main body 134 of a connecting element 130, and
in particular, be arranged within the main body 134 such as to be
spaced from the bearing surface 152 of the main body 134.
[0574] Provision may also be made however for the magnet element
190 to extend within the main body 134 up to the bearing surface
152.
[0575] In the seventeenth embodiment of the connecting device 100
that is illustrated in FIG. 54, a connection of the connecting
elements 130 and thus too of the parts 102, 104 to one another is
effected in that the magnet elements 190 interact magnetically with
one another, in particular, in that the magnet elements 190 attract
one another.
[0576] The parts 102, 104 are thus brought by means of the
connecting device 100 into a position in which the spacings of the
magnet elements 190 from each other are minimal.
[0577] Thereby, the parts 102, 104 do not necessarily have to be in
contact with one another and in particular do not have to abut
against each other. Rathermore, provision may be made for the parts
102, 104 to be arranged at a desired spacing A from each other.
[0578] Likewise, the connecting elements 130 of the connecting
device 100 do not have to be brought into engagement with one
another mechanically.
[0579] Consequently, it is not crucial for the connecting elements
130 to be arranged in grooves 110 which border on the contact
surfaces 106, 108 of the parts 102, 104.
[0580] Rathermore for example, provision may be made for at least
one connecting element 130 to be arranged in a groove 110 which
borders a side surface 310, an end face 312 of the part 102 for
example, that is oriented perpendicularly to the contact surface
106.
[0581] In particular, for the purpose of obtaining an aesthetically
appealing arrangement of the parts 102, 104, provision may be made
for the surfaces 108, 310, in which the grooves 110 and thus too
the connecting elements 130 are arranged, to be provided with a
respective cover element 314 after mounting the connecting elements
130.
[0582] For example, the cover element 314 can form an edge of the
part 102, 104.
[0583] In principle and as already indicated in the preceding
exemplary embodiments, a magnet element 190 is to be understood as
being a magnetically interacting element.
[0584] The two magnet elements 190 thus do not necessarily both
have to be magnetized. Rathermore for example, a magnetized magnet
element 190 and a magnetizable element and in particular a steel
element could be provided.
[0585] The seventeenth embodiment of the connecting device 100 that
is illustrated in FIG. 54 is suitable, in particular, for use in or
on furniture doors and office furniture having invisible, rapidly
mountable snap-action devices for fixing magnetically to a
door.
[0586] In all other respects, the seventeenth embodiment of a
connecting device 100 that is illustrated in FIG. 54 coincides in
regard to the construction and functioning thereof with the
sixteenth embodiment illustrated in FIGS. 50 to 53 so that, to that
extent, reference is made to the preceding description thereof.
[0587] An eighteenth embodiment of a connecting device 100 that is
illustrated in FIGS. 55 and 56 differs from the first embodiment
illustrated in FIGS. 5 to 9 substantially in that the screw element
132 is arranged on the connecting element 130 that is insertable
into a groove 110 in rotatable manner.
[0588] In place of a rotatable retaining element 142 for engaging
the screw element 132, an actuating element 316 for operating the
screw element 132 is provided instead.
[0589] In particular thereby, the actuating element 316 and the
screw element 132 form an angle-driven screw device 318.
[0590] As can be perceived from FIG. 56 in particular, the
angle-driven screw device 318 and in particular the actuating
element 316 is accessible laterally through an access boring 128 in
a part 102. On the one hand, the screw element 132 can be screwed
directly into the further part 104 without further elements.
[0591] However provision may also be made for the further part 104
to comprise a screw seating 230, to be provided with a screw
seating 230 or to be provided with a connecting element 130 which
is arrangeable in a groove 110 in the part 104 and which is itself
provided with a screw seating 230.
[0592] As an alternative to operation of a screw element 132 by
means of the actuating element 316, provision may also be made for
a nut to be operable by means of the actuating element 316 in order
to accommodate a screw arranged on the further part 104.
[0593] In particular, connections to non-wooden materials can be
established by means of connecting devices 100 of this type.
Furthermore, these connecting devices 100 are suitable for use in
or as shelf supports.
[0594] In all other respects, the eighteenth embodiment of a
connecting device 100 that is illustrated in FIGS. 55 and 56
coincides in regard to the construction and functioning thereof
with the first embodiment illustrated in FIGS. 5 to 9 so that, to
that extent, reference is made to the preceding description
thereof.
[0595] A nineteenth embodiment of a connecting device 100 that is
illustrated in FIG. 57 differs from the ninth embodiment
illustrated in FIGS. 32 to 34 substantially in that one of the
connecting elements 130 comprises a moveable retaining element 142
which is in the form of a latch hook 320.
[0596] In particular, the latch hook 320 is moveable into
engagement with a latch seating 322 which is arranged on the
further connecting element 130.
[0597] In particular, the latch hook 320 is arranged on the one
connecting element 130 in spring-like manner by means of a spring
element 264.
[0598] In particular, the latch hook 320 can be moved along the
direction of connection 170 from a rest position (see FIG. 57) in
which the latch hook 320 projects above the bearing surface 152 of
the connecting element 130 into a release position in which the
latch hook 320 is arranged substantially entirely within the main
body 134 of the connecting element 130.
[0599] The latch hook 320 and/or the latch seating 322 is
preferably provided with at least one inclined surface 324.
[0600] In particular, the inclined surface 324 is inclined to the
bearing surface 152 and/or to the contact surfaces 106, 108 of the
parts 102, 104.
[0601] The inclined surfaces 324 thereby enable the latch hook 320
to be pushed into the main body 134 when the parts 102, 104 and
thus too the connecting elements 130 are displaced in a transverse
direction 326 running parallel to the bearing surface 152 and/or to
the contact surfaces 106, 108.
[0602] Preferably however, this is only possible in a single
transverse direction 326.
[0603] Hereby, the parts 102, 104 and the connecting elements 130
are preferably formed and/or arranged in such a way that this
transverse direction 326 is opposed to the direction of the force
of gravity g for the purposes of disengaging the latch hook
320.
[0604] When the part 102 is subjected to a load in a transverse
direction 326 running parallel to the direction of the force of
gravity g, the latch hook 320 preferably remains in the latch
seating 322 so as to ensure a reliable and stable connection
between the parts 102, 104.
[0605] The nineteenth embodiment of a connecting device 100 that is
illustrated in FIG. 57 is suitable, in particular, for use as shelf
supports.
[0606] In all other respects, the nineteenth embodiment of a
connecting device 100 that is illustrated in FIG. 57 coincides in
regard to the construction and functioning thereof with the ninth
embodiment illustrated in FIGS. 32 to 34 so that, to that extent,
reference is made to the preceding description thereof.
[0607] A twentieth embodiment of a connecting device 100 that is
illustrated in FIGS. 58 to 60 differs from the ninth embodiment
illustrated in FIGS. 32 to 34 substantially in that the connecting
device 100 serves on the one hand for the connection of two parts
102, 104 and on the other hand, for the connection of the parts
102, 104 to one or more further parts and in particular to a base
construction 328.
[0608] In particular, a base construction 328 is a sub-construction
of a floor covering or a wall panel.
[0609] As can be perceived from FIGS. 58 and 60 in particular, the
connecting device 100 comprises a connecting element 130 which is
insertable into a groove 110 in one of the parts 102, 104.
[0610] For example, the connecting element 130 is formed in
one-piece manner and comprises, in addition to a part 330 that is
introducible into the groove 110, a projection 332 as well as an
embracing section 334.
[0611] The projection 332 serves, in particular, for the
arrangement and/or accommodation of the further part 104.
[0612] To this end in particular, the further part 104 is adapted
to be pushed onto the projection 332 by means of a recess 336 such
as a groove 110 for example.
[0613] The embracing section 334 of the connecting element 130 then
embraces the part 102 on a side surface 310 thereof running
transversely and in particular substantially perpendicularly to the
contact surface 106.
[0614] The connecting element 130 thus surrounds a section of the
part 102 in substantially a C-shape.
[0615] The embracing section 334 can, for example, extend parallel
to the projection 332 so that the further part 104 is also enclosed
in substantially a C-shape by the connecting element 130 in the
installed state thereof.
[0616] As can be perceived from FIG. 60 in particular, a through
opening 154 is provided between the projection 332 and the part 330
of the connecting element 130 forming the main body 134 of the
connecting element 130.
[0617] A screw 162 is introducible into this through opening 154
particularly in order to fix the connecting element 130 including
the part 102 or including both parts 102, 104 to the base
construction 328 and in particular to screw it firmly thereto.
[0618] One or more parts 102, 104 preferably do not abut directly
upon the base construction 328 due to the embracing section 334 of
the connecting element 130.
[0619] Rather, a spacing A.sub.2 between the one or the plurality
of parts 102, 104 is preferably formed by means of the embracing
section 334.
[0620] Furthermore, the parts 102, 104 are also preferably held
away from each other by a given spacing A.sub.1 by means of the
connecting element 130.
[0621] The twentieth embodiment of the connecting device 100 that
is illustrated in FIGS. 58 to 60 is suitable, in particular, as a
decking connector for the connection of boards (parts 102, 104) to
one another and to a decking-beam construction (base construction
328).
[0622] For the mounting process hereby, provision may be made for a
part 102 to be provided with one or more grooves 110 for
example.
[0623] At least one groove 110 is then provided with a connecting
element 130 by pushing the part 330 of the connecting element 130
that forms the main body 134 into the groove 110.
[0624] The embracing section 334 of the connecting element 130
thereby encloses the part 102 at the side surface 310 thereof.
[0625] In a next step, the part 102 together with the connecting
element 130 is laid on the base construction 328.
[0626] In particular, the embracing section 334 of the connecting
element 130 and the base construction 328 are brought into mutual
abutment and screwed together by means of one or more screws
162.
[0627] A further part 104 is then fixed to the base construction
328 by pushing a pre-prepared recess 336 or groove 110 onto the
projection 332 of the connecting element 130.
[0628] A further groove 110 into which a further connecting element
130 is in turn inserted is located or is provided on a side of the
part 104 that is located opposite that side of the part 104 which
serves to accommodate the projection 332 in order to fix it,
together with the further part 104, to the base construction
328.
[0629] The screws 162 merely have to be removed in order to release
the connection.
[0630] Preferably, the parts 102, 104 can then be displaced
relative to each other in order to remove individual parts 102,
104.
[0631] In all other respects, the twentieth embodiment of a
connecting device 100 that is illustrated in FIGS. 58 to 60
coincides in regard to the construction and functioning thereof
with the ninth embodiment illustrated in FIGS. 32 to 34 so that, to
that extent, reference is made to the preceding description
thereof.
[0632] A twenty-first embodiment of a connecting device 100 that is
illustrated in FIGS. 61 and 62 differs from the ninth embodiment
illustrated in FIGS. 32 to 34 substantially in that the connecting
device 100 comprises a plurality of spring elements 338 or latching
elements 340 by means of which the connecting elements 130 and thus
too the parts 102, 104 are connectible to one another, particularly
in latchable manner.
[0633] Hereby, the spring elements 338 or latching elements 340
comprise spring noses 342 or latch noses 344 which are moveable
into engagement with corresponding seatings 346.
[0634] For simplifying reference thereto hereinafter, the spring
elements 338 and the latching elements 340 will be referred to as a
whole as "latching elements 340".
[0635] In consequence, the spring noses 342 and the latch noses 344
will be referred to as a whole as "latch noses 344".
[0636] As can be perceived particularly from FIG. 61 in the case of
the twenty-first embodiment of a connecting device 100 that is
illustrated in FIGS. 61 and 62, both connecting elements 130 are
provided with latching elements 340 and with seatings 346 for the
latch noses 344 of the latching elements 340.
[0637] Hereby, the latching elements 340 and the seatings 346 are
arranged relative to each other in such a way that two latching
elements 340 of different connecting elements 130 can be guided
past each other and brought into engagement with the respectively
associated seating 346.
[0638] As can be perceived from FIG. 62 in particular, provision
may be made for example for each connecting element 130 to comprise
eight latching elements 340 and eight seatings 346.
[0639] Hereby, the latch noses 344 of the latching elements 340 are
preferably arranged at different spacings from the bearing surface
152 of the respective connecting element 130. Improved latching of
the connecting elements 130 and thus improved connection of the
parts 102, 104 can thereby be achieved.
[0640] As can be perceived from FIG. 61 for example, adjacent
latching elements 340 are preferably oriented in such a way that
the latch noses 344 of the latching elements 340 project away from
one another in different directions.
[0641] In addition, provision may be made for each connecting
element 130 itself to comprise two or more latching elements 340
which are arranged next to each other, wherein directly bordering
latching elements 340 are preferably formed and/or arranged in such
a manner that their latch noses 344 project away from each other in
different directions.
[0642] In all other respects, the twenty-first embodiment of a
connecting device 100 that is illustrated in FIGS. 61 and 62
coincides in regard to the construction and functioning thereof
with the ninth embodiment illustrated in FIGS. 32 to 34 so that, to
that extent, reference is made to the preceding description
thereof.
[0643] A twenty-second embodiment of a connecting device 100 that
is illustrated in FIGS. 63 to 67 differs from the twenty-first
embodiment illustrated in FIGS. 61 and 62 substantially in that
there is provided only one connecting element 130 which comprises
spring elements 338 and/or latching elements 340.
[0644] In regard to this embodiment too, standardized reference
will be made exclusively to latching elements 340 in the following.
However, these latching elements 340 could also be simple spring
elements 338.
[0645] In the case of the twenty-second embodiment of a connecting
device 100 that is illustrated in FIGS. 63 to 67, there is provided
one connecting element 130 which is introducible into a groove 110
and which has two rows 348 of latching elements 340.
[0646] The rows 348 are arranged in parallel with each other.
[0647] Latch noses 344 of the latching elements 340 of a row 348
project away in the same direction.
[0648] Hereby, the latch noses 344 of each one of the rows 348 are
arranged along a path in the form of an arc of a circle.
[0649] As can be perceived from FIGS. 65 and 67 in particular, the
latching elements 340 are arranged in such a way that the latch
noses 344 of the latching elements 340 project away in a direction
turned away from the respective other row 348.
[0650] Hereby, the length of the latching elements 340, i.e. the
spacing of the latch noses 344 of the latching elements 340 from
the bearing surface 152 of the connecting element 130 is preferably
selected in such a way that the latch noses 344 are insertable into
a groove 110 of the type illustrated in FIGS. 1 to 4 and are
latchable on the undercut surfaces 122 of the groove 110.
[0651] A simple latching connection between two parts 102, 104 can
thus be established using just one connecting element 130 and two
grooves 110.
[0652] Preferably the latch noses 344 are provided with (not
illustrated) inclined surfaces so that the parts 102, 104 can be
drawn together by the process of latching the latch noses 344.
[0653] In all other respects, the twenty-second embodiment of a
connecting device 100 that is illustrated in FIGS. 63 to 67
coincides in regard to the construction and functioning thereof
with the twenty-first embodiment illustrated in FIGS. 61 and 62 so
that, to that extent, reference is made to the preceding
description thereof.
[0654] A twenty-third embodiment of a connecting device 100 that is
illustrated in FIGS. 68 to 70 differs from the twenty-first
embodiment illustrated in FIGS. 61 and 62 substantially in that one
or more locking elements 350 are provided in place of the latching
elements 340.
[0655] In particular, a locking element 350 forms a retaining
element 142.
[0656] Hereby, the locking element 350 can be in the form of a
metallic bent part 352 for example.
[0657] As can be perceived from FIG. 68 in particular, the locking
element 350 is receivable in a seating 354 of a connecting element
130.
[0658] The locking element 350 is preferably an element which is
different from the main body 134 of the connecting element 130 and
which, in particular, is fixable to the main body 134 in releasable
manner.
[0659] For example, the locking element 350 comprises two
engagement projections 146 which are formed and/or arranged such as
to be movable relative to the main body 134 of the connecting
element 130.
[0660] The further connecting element 130 comprises an actuating
element 316 for actuating the locking element 350.
[0661] The actuating element 316 is in the form of an eccentric cam
element for example.
[0662] The actuating element 316 is preferably accessible through a
lateral access boring 128 in one of the parts 102, 104 particularly
in order to rotate the actuating element 316 by means of a wrench
and hence actuate the locking element 350.
[0663] As can be perceived from FIGS. 69 and 70 in particular, the
locking element 350 can be actuated by means of the actuating
element 316, in particular, by moving the engagement projections
146 away from each other by means of the actuating element 316 and
thereby introduced into the engagement sections 148 in the
connecting element 130 upon which the actuating element 316 is
arranged.
[0664] Due to the fact that the locking element 350 and the
actuating element 316 are arranged on mutually differing connecting
elements 130, the lever arm ratios for actuating the locking
element 350 can be optimized. The mechanical loading of the
connecting device 100 during the process of locking it can thereby
be reduced, whilst the stability and reliability of the connection
is preferably retained or even improved.
[0665] In all other respects, the twenty-third embodiment of a
connecting device 100 that is illustrated in FIGS. 68 to 70
coincides in regard to the construction and functioning thereof
with the twenty-first embodiment illustrated in FIGS. 61 and 62 so
that, to that extent, reference is made to the preceding
description thereof.
[0666] A twenty-fourth embodiment of a connecting device 100 that
is illustrated in FIGS. 71 to 74 differs from the twenty-first
embodiment illustrated in FIGS. 61 and 62 substantially in that a
clamping device 356 is provided in place of the latching elements
340.
[0667] The clamping device 356 comprises one or more clamping
projections 358 and one or more clamping elements 360.
[0668] A clamping projection 358 is arranged on one of the
connecting elements 130 that are insertable into a groove 110 for
example.
[0669] The clamping elements 360, four clamping elements 360 for
example, are arranged on the further connecting element 130.
[0670] In particular, the clamping elements 360 are arranged on
mutually opposite sides of a clamping seating 362.
[0671] The clamping projection 358 is substantially
parallelepipedal.
[0672] The clamping elements 360 are preferably provided with a
material having a high coefficient of friction at the ends thereof
coming into contact with the clamping projection 358 or are formed
from a material having a high coefficient of friction.
[0673] The clamping elements 360 are preferably formed in yielding,
resilient and/or spring-like manner and/or are arranged on the main
body 134 of the connecting element 130.
[0674] The clamping elements 360 preferably project into the
clamping seating 362 at an angle to the bearing surface 152. In
addition, the clamping elements 360 are preferably directed away
from the bearing surface 152.
[0675] The clamping elements 360 can easily be moved to the side
when pushing the clamping projection 358 into the clamping seating
362. The clamping projection 358 can thus be inserted into the
clamping seating 362 without substantial resistance (see FIGS. 73
and 74).
[0676] The connection between the connecting elements 130 and thus
the connection between two parts 102, 104 can thus be established
in a simple manner.
[0677] The clamping projection 358 has to be withdrawn from the
clamping seating 362 in order to release the connection.
[0678] Due to the shape and design of the clamping elements 360
here however, there is a greater resistance due, in particular, to
the fact that the clamping elements 360 are moved onto the clamping
projection 358 by the inclined arrangement and alignment and as a
result the clamping force is reinforced still more.
[0679] It follows therefore that the clamping device 356 is a
self-locking clamping device 356.
[0680] The clamping elements 360 can be formed by thrust collars
for example.
[0681] In particular, the clamping projection 358 is a
substantially parallelepipedal spigot.
[0682] In all other respects, the twenty-fourth embodiment of the
connecting device 100 that is illustrated in FIGS. 71 to 74
coincides in regard to the construction and functioning thereof
with the twenty-first embodiment illustrated in FIGS. 61 and 62 so
that, to that extent, reference is made to the preceding
description thereof.
[0683] A twenty-fifth embodiment of a connecting device 100 that is
illustrated in FIG. 75 differs from the twenty-first embodiment
illustrated in FIGS. 61 and 62 substantially in that the latching
elements 340 and the seatings 346 for the latching elements 340 are
substantially spherical.
[0684] Hereby, the latching elements 340 and/or the seatings 346
for the latching elements 340 are preferably resilient and/or
yielding.
[0685] For example, provision may be made for the spherical
latching elements 340 to be deformable in order to enable them to
be inserted into the likewise spherical seatings 346.
[0686] In the twenty-fifth embodiment of the connecting device 100
that is illustrated in FIG. 75, the latching elements 340 and the
seatings 346 are provided on mutually differing connecting elements
130.
[0687] Hereby, the spherical latching elements 340 are arranged at
different spacings from the bearing surface 152. Optimal latching
of the parts 102, 104 to one another can thereby be achieved.
[0688] In particular in the case where the seatings 346 for the
latching elements 340 are always arranged at the same spacing from
the bearing surface 152 of the connecting element 130 concerned,
provision may be made for the spherical latching elements 340 to be
introduced successively into the seatings 346 and latched
thereto.
[0689] Preferably, latching of the connecting device 100 in
different positions and in particular, at different spacings from
the bearing surfaces 152 of the connecting elements 130 can thereby
be realized.
[0690] In all other respects, the twenty-fifth embodiment of a
connecting device 100 that is illustrated in FIG. 75 coincides in
regard to the construction and functioning thereof with the
twenty-first embodiment illustrated in FIGS. 61 and 62 so that, to
that extent, reference is made to the preceding description
thereof.
[0691] A twenty-sixth embodiment of a connecting device 100 that is
illustrated in FIGS. 76 to 78 differs from the twenty-fifth
embodiment illustrated in FIG. 75 substantially in that the
latching elements 340 are substantially in the form of a section of
a circular cylinder and are introducible into seatings 346
corresponding thereto that are substantially in the form of a
section of a circular cylinder.
[0692] In all other respects, the twenty-sixth embodiment of a
connecting device 100 that is illustrated in FIGS. 76 to 78
coincides in regard to the construction and functioning thereof
with the twenty-fifth embodiment illustrated in FIG. 75 so that, to
that extent, reference is made to the preceding description
thereof.
[0693] An alternative design of a groove 110 is illustrated in
FIGS. 79 and 80.
[0694] This groove 110 is in the form of a partial groove 364.
[0695] The bottom surface of the groove 118 in this partial groove
364 actually extends in the form of an arc of a circle from the
contact surface 106 of the part 102 into the part 102. However, the
bottom surface of the groove 118 does not end again at the contact
surface 106, but rather, within the part 102 or else at a side
surface 310 of the part 102 (not illustrated in the drawings).
[0696] In the case of the embodiment of a groove 110 that is
illustrated in FIGS. 79 and 80, the bottom surface 118 of the
groove ends at a stop surface 366 of the groove 110.
[0697] In particular, the stop surface 366 runs transversely to the
contact surface 106.
[0698] The stop surface 366 preferably bounds the base section 112
and the undercut sections 114.
[0699] By suitably shortening the construction of the connecting
elements 130, preferably all of the connecting elements 130 that
are arrangeable in a groove 110 in accordance with FIGS. 1 to 4 are
also arrangeable in a partial groove 364 in accordance with FIGS.
79 and 80.
[0700] The partial groove 364 is producible by means of a (not
illustrated) end-milling cutter for example.
[0701] A twenty-seventh embodiment of a connecting device 100 that
is illustrated in FIG. 81 differs from the twenty-fourth embodiment
illustrated in FIGS. 71 to 74 substantially in that the connecting
device 100 comprises a securing device 368.
[0702] The connecting element 130 is preferably securable from
unwanted displacement thereof within and/or along the groove 110 by
means of the securing device 368.
[0703] In particular, the securing device 368 comprises a securing
element 370 in the form of a securing projection which, in the
installed state of the connecting element 130, comes into abutment,
in particular, on a contact surface 106, 108 of a part 102, 104 and
thereby secures the connecting element 130 against unwanted
displacement within and/or along the groove 110.
[0704] In particular, the securing element 370 can be clamped
between the parts 102, 104, between the contact surfaces 106, 108
of the parts 102, 104 for example, in order to secure the
connecting element 130.
[0705] In all other respects, the twenty-seventh embodiment of a
connecting device 100 that is illustrated in FIG. 81 coincides in
regard to the construction and functioning thereof with the
twenty-fourth embodiment illustrated in FIGS. 71 to 74 so that, to
that extent, reference is made to the preceding description
thereof.
[0706] A twenty-eighth embodiment of a connecting device 100 that
is illustrated in FIGS. 82 to 87 differs from the twenty-seventh
embodiment illustrated in FIG. 81 in particular in that the
securing device 368 comprises two pairs of securing elements 370
which are arranged at mutually opposite end regions 374 of the
respective connecting element 130 taken with respect to a direction
of insertion 372 of the connecting elements 130.
[0707] In particular hereby, the securing elements 370 are securing
elements 370 that are in the form of and/or are arranged in
resilient, yielding and/or spring-like manner.
[0708] The securing elements 370 are preferably moved automatically
into a release position when inserting the connecting elements 130
into the grooves 110.
[0709] As soon as the connecting elements 130 are arranged in the
given position in the groove 110 and in particular as soon as the
bearing surface 152 of the connecting element 130 is oriented in
parallel with and in particular is flush with the contact surface
106, 108 of the part 102, 104, the securing elements 370 preferably
automatically reach a retaining position in which further
displacement of the connecting element 130 within and/or along the
groove 110 is effectively prevented.
[0710] The securing elements 370 are then supported, in particular,
on the contact surface 106, 108 of at least one of the parts 102,
104.
[0711] In the case of the twenty-eighth embodiment of the
connecting device 100 that is illustrated in FIGS. 82 to 87, the
actual connection of the two connecting elements 130 and the parts
102, 104 to one another is effected by a guidance device 238.
[0712] The guidance device 238 comprises a guidance element 240
which is arranged on a connecting element 130 and comprises one or
more guidance projections 242.
[0713] In particular, the guidance element 240 is introducible into
a guidance groove 244 of the further connecting element 130.
[0714] This guidance groove 244 comprises a guidance section 250
which is inter-engageable by the guidance element 240 by means of
the guidance projections 242.
[0715] In particular, the guidance device 238 comprises a camming
guide 376 which is formed by the guidance groove 244.
[0716] The camming guide 376 serves, in particular, for guiding the
guidance element 240 along a given guide path.
[0717] This guide path has varying spacings along the guidance
groove 244 from the contact surfaces 106, 108 of the parts 102, 104
and/or from the bearing surfaces 152 of the connecting elements
130.
[0718] In particular, the camming guide 376 provides a local
minimum region 378 which is surrounded by two local or global
maximum regions 380.
[0719] The maximum regions 380 are surrounded by run out regions
382 on the side thereof remote from the minimum region 378.
[0720] For the purposes of connecting the connecting elements 130
as well as the parts 102, 104 to one another, the connecting
elements 130 are firstly arranged on the parts 102, 104.
[0721] In a next step, the parts 102, 104 together with the
connecting elements 130 arranged thereon are displaced relative to
one another so that the guidance element 240 of the one connecting
element 130 enters into the guidance groove 244 of the further
connecting element 130.
[0722] In particular thereby, the parts 102, 104 and the connecting
elements 130 are displaced in parallel with the contact surfaces
106, 108 of the parts 102, 104.
[0723] Hereby, the guidance projection 242 firstly comes into
engagement with a run out region 382 and is then fed across the
maximum region 380 into the minimum region 378.
[0724] Due to the further maximum region 380 following this minimum
region 378, this minimum region 378 is a stable position for the
guidance projection 242 along the guide path formed by means of the
camming guide 376.
[0725] The connecting elements 130 are thus connected to one
another in stable manner when the guidance projection 242 is
arranged in the minimum region 378 of the camming guide 376 (see in
particular, FIG. 86).
[0726] If so required, the guidance projection 242 together with
the appertaining connecting element 130 and the appertaining part
102, 104 can also be pushed over the further maximum region 380 as
well as out of the further run out region 382.
[0727] The connecting elements 130 are thus displaceable entirely
past each other if necessary.
[0728] As can be perceived from FIGS. 83 and 86 in particular, an
indentation 384 in a region remote from the bearing surface 152 can
be provided in one or more connecting elements 130.
[0729] This indentation 384 is in the form of an arc of a circle
for example.
[0730] Such an indentation 384 can be advantageous, in particular,
when the connecting element 130 is intended to be arranged in a
flat part 102, 104 and further guidance elements 240 are provided
on the same part 102, 104 in addition to this connecting element
130.
[0731] For example, if two grooves 110 for accommodating connecting
elements 130 are arranged on mutually opposite sides of a part 102,
104 and the grooves 110 project so far into the part 102, 104 that
the grooves 110 intersect within the region of the bottom surfaces
of the grooves 118, the indentation 384 can make it possible for
two connecting elements 130 to be arranged in the part 102, 104
despite such an intersection.
[0732] In all other respects, the twenty-eighth embodiment of a
connecting device 100 that is illustrated in FIGS. 82 to 87
coincides in regard to the construction and functioning thereof
with the twenty-seventh embodiment illustrated in FIG. 81 so that,
to that extent, reference is made to the preceding description
thereof.
[0733] A twenty-ninth embodiment of a connecting device 100 that is
illustrated in FIGS. 88 to 92 differs from the twenty-eighth
embodiment illustrated in FIGS. 82 to 87 substantially in that one
of the connecting elements 130 and in particular the connecting
element 130 comprising the guidance groove 244 is provided with a
retaining projection 138 on only one side.
[0734] In particular, this connecting element 130 can thus be
inserted into a groove 110 which comprises only one undercut
section 114 that extends away from the base section 112.
[0735] Such a groove 110 can be advantageous when using thin and
less sturdy parts 102, 104 for example.
[0736] In principle, the reduction of the groove 110 and/or the
connecting elements 130 to only one undercut section 114 and/or
only one retaining projection 138 can be advantageous in all of the
described and conceivable variants of grooves 110 and connecting
elements 130.
[0737] In all other respects, the twenty-ninth embodiment of a
connecting device 100 that is illustrated in FIGS. 88 to 92
coincides in regard to the construction and functioning thereof
with the twenty-eighth embodiment illustrated in FIGS. 82 to 87 so
that, to that extent, reference is made to the preceding
description thereof.
[0738] A thirtieth embodiment of a connecting device 100 that is
illustrated in FIGS. 93 to 97 differs from the twenty-eighth
embodiment illustrated in FIGS. 82 to 87 substantially in that one
of the connecting elements 130, the connecting element 130
comprising the guidance element 240 for example, is not envisaged
for insertion into a groove 110, but rather it comprises two
plug-in sections 386 for plugging the connecting element 130 into
mutually corresponding (not illustrated) seatings of a part 102,
104.
[0739] The plug-in sections 386 can, for example, be provided with
ribbing, lamella and/or other retaining elements in order to
connect the connecting element 130 to the corresponding part 102,
104 in a stable manner.
[0740] In all other respects, the thirtieth embodiment of a
connecting device 100 that is illustrated in FIGS. 93 to 97
coincides in regard to the construction and functioning thereof
with the twenty-eighth embodiment illustrated in FIGS. 82 to 87 so
that, to that extent, reference is made to the preceding
description thereof.
[0741] A thirty-first embodiment of a connecting device 100 that is
illustrated in FIGS. 98 and 99 differs from the fifteenth
embodiment illustrated in FIGS. 47 to 49 substantially in that the
connecting elements 130 themselves form hinge elements 272 of the
hinge device 274.
[0742] Hereby, the connecting elements 130 are formed in such a way
that they are receivable in partial grooves 364 (see FIGS. 79 and
80).
[0743] In the case of these partial grooves 364 in particular,
provision is made for the bottom surfaces of the grooves 118 of the
respective partial groove 364 to border on a contact surface 106,
108 at one side and on a side surface 310 of the respective part
102, 104 at the other side.
[0744] The connecting elements 130 arranged in the partial grooves
364 are fixable in the partial grooves 364 and thus in the parts
102, 104 by means of screws 162.
[0745] The connecting elements 130 and thus too the parts 102, 104
are pivotal about the pivotal axis 284 by means of the hinge device
274.
[0746] As is apparent from a comparison of FIGS. 98 and 99 in
particular, a pivotal movement of the parts 102, 104 relative to
each other through approximately 90.degree. in particular can be
effected. The connecting device 100 is thus suitable, in
particular, for fixing doors to a carcass of a cabinet.
[0747] In particular, the partial grooves 364 in the thirty-first
embodiment of a connecting device 100 that is illustrated in FIGS.
98 and 99 are producible by placing the parts 102, 104 directly on
one another and then providing a single continuous groove 110 in
accordance with FIGS. 1 to 4.
