Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of Austrian Patent
application No. A 1794/2008, filed Nov. 19, 2008, and European
Patent Application No. 09011303.6, filed Sep. 3, 2009, both of
which are incorporated herein by reference as if fully set
forth.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to a buckle for connecting first and
second straps, wherein this buckle comprises a buckle body that has
left and right side parts with respect to the longitudinal
direction of the straps to be connected and first and second cross
bars running transverse to the longitudinal direction of the straps
to be connected between the left and right side parts and wherein
this buckle comprises a movable middle bar extending transverse to
the longitudinal direction of the straps to be connected between
the left and right side parts, wherein this middle bar is supported
so that it can move relative to the left and right side parts in
the longitudinal direction of the straps to be connected, wherein
the middle bar rests on resting bars of the side parts.
[0004] 2. Description of Related State of the Art
[0005] For connecting two straps, wherein the length of at least
one strap is adjustable, buckles with fixed cross bars are known.
Such buckles are also designated as tri-glide buckles or also as
ladder-lock buckles (especially if more than three cross bars are
provided).
[0006] It is further already known to arrange a middle cross bar
that is designated below as a middle bar so that it can move
relative to a buckle body in the longitudinal direction of the
straps to be connected. The holding force against the pulling out
of the length-adjustable strap is therefore increased. In the case
of such a known construction, the middle bar made from metal rests
on, on both sides, resting bars of the buckle body similarly made
from metal. Side guide bars that are bent toward the side of the
buckle body on which the middle bar rests on the resting bars are
adjacent to the resting bars, so that they point upward at an
angle. In the guide bars, window cutouts are formed into which
angled end sections of the middle bar project. The angles of the
middle bar are here directed opposite the angles of the guide bars.
Therefore, the middle bar is held in the window cutouts so that it
can move in the longitudinal direction of the straps to be
connected but is held in the guide bars secured from being pulled
out from the window cutouts. In the case of this known buckle, in
order to ensure that the middle bar does not fall out from the
window cutouts of the guide bars, the tolerances for the
construction of the buckle must be relatively small. The bent end
sections of the middle bar here lead to additional production
complexity.
SUMMARY OF THE INVENTION
[0007] The object of the invention is to provide a buckle of the
type noted above in which a reliable support of the middle bar is
achieved and which can be produced economically.
[0008] This is realized according to the invention in that a bent
support bar extends from the resting bars, wherein this support bar
has a section lying in front of each end face of the middle bar and
a section with a cutout in which the respective end of the middle
bar projects, and this section faces toward the resting bar from
which the support bar extends.
[0009] In the case of a buckle according to the invention, a bent
support bar extends from the resting bars for the middle bar. This
support bar has a section lying in front of the adjacent end side
of the middle bar, wherein this section is used as a stop for the
middle bar against a shift of the middle bar in its axial
direction, and this support bar further has a section that points
in the direction toward the resting bar from which the support bar
extends and has a cutout into which the respective end of the
middle bar projects. This cutout extends in the longitudinal
direction of the straps to be connected and its ends are used as
stops for the middle bar, in order to limit the ability of the
middle bar to move in the longitudinal direction of the straps to
be connected.
[0010] Therefore, with the ability for simple production, a
reliable holding of the middle bar on the buckle body can be
achieved.
[0011] Advantageously, the cutouts holding the ends of the middle
bar extend from the edge of the support bar running in the
direction of the longitudinal extent of the straps to be connected.
This edge is directed toward the resting bar from which the support
bar extends and rests on the resting bar or has a spacing from the
resting bar that is less than the thickness of the middle bar
measured perpendicular to the surface of the resting bar on which
the middle bar lies, so that the middle bar cannot be guided
through the gap between the edge of the support bar and the resting
bar.
[0012] Advantageously, the buckle body of the buckle according to
the invention can be formed by a bent plate provided with
corresponding cutouts.
[0013] The middle bar is advantageously formed in the shape of a
flat plate.
[0014] In order to prevent undesired pulling of the
length-adjustable strap from the buckle body, in the case of
preferred embodiments of the invention, it can be provided that the
buckle has at least one elastic biasing element that biases the
middle bar in a direction parallel to the longitudinal direction.
Through the biasing applied by the elastic biasing element, the
strap wrapped around the middle bar is pressed against one of the
cross bars, also without having to be pulled on the strap. This can
thus be used, first, for preventing the strap from accidentally
being pulled from the buckle body in the unbiased state.
Furthermore, through corresponding dimensioning of the elastic
biasing element, the holding forces produced by clamping the strap
between the middle bar and the cross bar are generally increased,
that is, also in the state in which it is pulled on the strap. A
coil spring, for example, can be used as the biasing element. The
elastic biasing element is favorably arranged within one of the
bent support bars. Especially preferred embodiments of the
invention provide that, within each of the bent support bars, there
is at least one elastic biasing element.
[0015] The buckle can have, as shown farther below, a single buckle
body on which two straps are attached. Alternatively, however, a
two-part or multi-part construction of the buckle is also
conceivable. Thus it can be provided, e.g., that the buckle has an
additional buckle body that can be connected detachably to the
buckle body with the bent support bars by a connection device,
advantageously without a tool. Here, without a tool is to be
understood that the connection device can be activated by hand,
that is, without the use of a tool, in order to disconnect from
each other the buckle bodies connected to each other and/or to
reconnect them to each other. In the case of such two-part or
multi-part buckles, it is then preferably provided that one of the
straps to be connected to each other is mounted directly on the
buckle body and the other of the straps to be connected is mounted
directly on the additional buckle body. The attachment of this
strap of the additional buckle body on the buckle body is then
performed by the connection of the buckle body to the additional
buckle body by the connection device. In the case of these
variants, preferred constructions provide that the connection
device has a latch device for the detachable latching of the
additional buckle body with the buckle body. The elastic biasing
element noted above biases the middle bar preferably in a direction
pointing away from the additional buckle body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0031] A first embodiment for a buckle according to the invention
is explained below with reference to FIGS. 1 to 8.
[0032] The buckle of the first embodiment is used for connecting
the straps 6, 7 that are shown in FIG. 3 only by dashed lines and
that extend starting from the buckle in a longitudinal direction 5
(strap 6) or against this longitudinal direction 5 (strap 7). The
buckle has a buckle body 1 made from one piece with a first and a
second cross bar 2, 3. A middle bar 4 that can move to a limited
extent in the longitudinal direction 5 is held on the buckle body
1--with respect to the longitudinal direction 5 in the region
between the first and the second cross bar 2, 3.
[0033] The first strap 6 is guided around the first cross bar 2,
wherein, for attaching on the first cross bar 2, a loop is formed
by stitching 8 that is indicated by a dotted line in FIG. 3. The
second strap is fed from the opposite side underneath the second
cross bar 3 and the middle bar 4, guided around the middle bar 4
and through the intermediate space 9 between the middle bar 4 and
the second cross bar 3 and further fed back underneath the second
cross bar 3. The length of the second strap 7 is determined
according to the overlap of the end 10 of the second strap 7 with
the section of the strap 7 extending toward the buckle.
[0034] The first cross bar 2, second cross bar 3, and middle bar 4
extend transverse to the longitudinal direction 5 of the straps 6,
7.
[0035] The first and second cross bars 2, 3 extend between right
and left side parts 11, 12 of the buckle body 1 with respect to the
longitudinal direction 5. The middle bar 4 crosses over the free
space between the side parts 11, 12 and lies with its two end
sections on surfaces of resting bars 13a, 13b of the right and left
side parts 11, 12 directed toward the front side of the buckle.
[0036] The resting bars 13a, 13b have a smooth construction and
their surfaces on which the middle bar 4 lies, lie in a common
plane.
[0037] The resting bars 13a, 13b are considered not only the
sections of the buckle body 1 on which the middle bar 4 actually
lies in its different possible displacement positions, but also its
imaginary, straight-line projections in and opposite the
longitudinal direction 5 up to the respective edge of the buckle
body 1. For illustration, the imaginary lines by which the resting
bars 13a, 13b are delimited by the cross bars 2, 3 are shown with
dashed lines in FIG. 4.
[0038] Support bars 16a, 16b extend from the edges 14, 15 of the
flat resting bars 13a, 13b extending away from each other in the
longitudinal direction 5 of the straps 6, 7 to be connected,
wherein these support bars have a bent profile viewed in cross
section (cf. FIG. 6, the section line B-B of this cross section
runs transverse to the longitudinal direction 5). In a first
section, the support bars 16a, 16b extend away from the plane of
the surfaces of the resting bars 13a, 13b on which the middle bar 4
lies, wherein they extend in the region next to the end faces 17a,
17b of the middle bar 4. Through the further bent profile, they
extend in connection to a peak point 18, in turn, in the direction
toward the respective resting bar 13a, 13b from whose edge 14, 15
they project. These sections extending in the direction toward the
respective resting bar 13a, 13b have cutouts 19a, 19b starting from
their ends extending in the longitudinal direction 5 in which the
two ends of the middle bar 4 project. The edges 20, 21 limiting the
respective cutout 19a, 19b in the longitudinal direction 5 form
stops for the middle bar 4, in order to limit the range of movement
of the middle bar 4 in and against the longitudinal direction 5.
The edge 22 of the cutout 19a, 19b extending parallel to the
longitudinal direction 5 forms a guide for the middle bar 4 that
limits the lift of the middle bar 4 from the respective resting bar
13a, 13b. Here, only play sufficient for the movement of the middle
bar 4 must be provided. Advantageously, this play measured
perpendicular to the resting bar 13a, 13b is less than 2 mm,
especially preferred less than 1 mm.
[0039] In the illustrated embodiment, the support bars 16a, 16b
have a continuous, arc-shaped profile viewed in cross section. It
would also be conceivable and possible, for example, that the
support bars 16a, 16b are connected to the respective resting bar
13a, 13b by a more or less sharp kink. The section lying in front
of the respective end face of the middle bar 4 could then have a
flat construction and this section could be connected by a more or
less sharp bend to the section having the cutout 19a, 19b. As a
whole, in turn, bent support bars 16a, 16b are formed whose free
ends each point toward the resting bar 13a, 13b from which the
support bars extend.
[0040] In this embodiment, the first cross bar 2 has a middle, bent
region 23, in order to form a grip element on which the buckle body
1 can be gripped and tilted, in order to pull the second strap 7
further from the buckle and to increase the length of the second
strap 7.
[0041] Advantageously, the buckle body 1 is made from metal. For
the middle bar 4, a construction from metal is also preferred.
[0042] The buckle body 1 can advantageously be formed from a plate
on which the corresponding separating and shaping operations are
performed. For forming the support bars 16a, 16b, the plate is
shaped with the already formed cutouts 19a, 19b by bending.
[0043] The thickness of the plate is here advantageously greater
than 1 mm, especially preferred greater than 1.5 mm.
[0044] The thickness of the middle bar 4 is advantageously greater
than 1 mm, especially preferred greater than 1.5 mm.
[0045] For example, the buckle body 1 and the middle bar 4 could
have a thickness of 2 mm.
[0046] In principle, however, it would also be conceivable and
possible to form the buckle body 1 from several parts connected
rigidly to each other.
[0047] In other words, the buckle body 1 could also be described
such that it has a main section lying in a plane with a window
cutout that is crossed over by the displaceable middle bar 4,
wherein the bent support bars 16a, 16b extend from this main
section on both sides. Furthermore, a bent region 23 for forming a
grip part can be formed from this flat main section.
[0048] In principle, however, it would also be conceivable and
possible to form the buckle body 1 with more than two fixed cross
bars 2, 3 and/or to provide more than one middle bar 4 that is held
on the buckle body 1 so that it can move in the described way.
[0049] In the scope of this publication, when straps are mentioned,
belts and other flexible strip-shaped parts should also be
included, especially also load-bearing, holding, and securing
belts.
[0050] In the second embodiment of the invention according to FIGS.
9 to 13, essential parts are discussed analogous to the first
embodiment, so that, in this respect, the above description of the
first embodiment could be referenced. Below we will essentially
discuss the differences between the first and the second
embodiment.
[0051] A first difference lies in that, in the case of the second
embodiment, the buckle has a buckle body 1 formed according to the
invention and, in addition, an additional buckle body 24. These two
buckle bodies 1 and 24 can be connected detachably to each other by
a connection device explained as an example farther below in
detail. The first strap 6 is here attached, in contrast to the
first embodiment, not on the buckle body 1, but instead on the
additional buckle body 24. For this purpose, the latter has a third
cross bar 31, in order to be able to wrap the first strap 6 through
the opening 32. The first strap 6 can be fixed on the additional
buckle body 24, e.g., by stitching 8 analogous to the first
embodiment. In the second embodiment, the strap 7 to be connected
to the first strap 6 by the buckle is attached to the buckle body
1, also like in the first embodiment. Analogous to the first
embodiment, the second strap 7 is fed from the opposite side
underneath the second cross bar 3 and the middle bar 4, guided
around the middle bar 4 and through the intermediate space 9
between the middle bar 4 and the second cross bar 3, and
furthermore fed back underneath the second cross bar. The length of
the second strap 7 is determined according to the overlap of the
end 10 of the second strap 7.
[0052] In order to prevent undesired loosening or displacement of
the second strap 7 in the non-tensioned state and/or to generally
increase the holding forces that are holding the second strap 7 on
the buckle body 1, there can be at least one elastic biasing
element 25 that biases the middle bar 4 in a direction parallel to
the longitudinal direction 5, as shown in the second embodiment. In
the illustrated embodiment, it involves two such elastic biasing
elements 25. These are each arranged within the bent support bars
16a and 16b. As the elastic biasing element 25, all of the suitably
elastic bodies known in the state of the art can be used. In the
illustrated embodiment, each of the elastic biasing elements 25
involves a coil spring. The one end of the elastic biasing element
is fixed in the respective bent support bar 16a or 16b. On the
opposite end of the elastic biasing element 25 lies the middle bar
4, so that the middle bar 4 is here biased or spring-loaded in a
direction 33 parallel to the longitudinal direction 5. In the
illustrated embodiment, the biasing is guided in the direction
toward the second cross bar 3, so that the strap 7 is clamped by
the biasing of the biasing element 25 between the middle bar 4 and
the second cross bar 3. FIG. 10 shows the section E-E from FIG. 9
in which the position of the elastic biasing element is to be seen
especially well in the support bar 16a. The support bars 16a, 16b,
as well as the resting bars 13a and 13b and the cutouts 19a and
19b, can be constructed as shown in the first embodiment with
reference to FIGS. 1 to 8. This also applies especially for all of
the details explained with reference to FIGS. 4 to 8. Deviating
from the first embodiment, notches 26 are provided in the second
embodiment in the support bars 16a and 16b. However, these
differences do not change the general construction and function of
the right and left side parts 11 and 12 or the support bars 16a and
16b. The notches 26 can also be eliminated accordingly, so that the
side parts 11 and 12 could be constructed up to the additional
biasing elements in their interaction with the middle bar 4 and the
cross bars 1 and 2 like in the first embodiment. Accordingly, in
the first embodiment, a biasing of the middle bar 4 in a direction
parallel to the longitudinal direction 5 could also be performed,
if the elastic biasing elements 25 of the second embodiment are
integrated there.
[0053] As already explained, the buckle of the second embodiment
according to the invention has a two-part construction. It has an
additional buckle body 24 that can be connected detachably to the
buckle body 1 by a connection device, advantageously without a
tool. Such two-part buckles, and also buckles with more than two
parts, are basically known in the state of the art in a plurality
of constructions. The embodiment shown here shows only one of many
possible variants. The same applies for the connection device for
connecting the buckle body 1 and the additional buckle body 24. In
the illustrated embodiment, the connection device involves a latch
device for the detachable latching of the additional buckle body 24
with the buckle body 1. In the illustrated embodiment, the
connection device or latch device comprises a female plug-in part
29 in which a male plug-in part 28 can be fixed detachably. For
this purpose, the male plug-in part 28 has shoulders 30, as to be
seen especially in FIG. 13, which are in active connection in the
inserted state according to FIGS. 9 and 11 with counterparts of the
activation lever 27 not shown in detail here, so that the two
buckle bodies 1 and 24 are latched to each other in the connected
position according to FIGS. 9 and 11. By activating the activation
lever 27, especially by hand, the additional buckle body 24 can
then be pulled out from the buckle body 1, so that the two buckle
bodies, as shown in FIGS. 12 and 13, are separated from each other.
Such buckle connections are known, as already mentioned, in a
plurality of embodiments, so that here no additional explanations
appear necessary. In principle, the invention can be combined
together with all of the possible, known connection devices or
embodiments of buckles with two or more parts. The variant shown
here is only one example. In particular, it is to be noted that it
does not absolutely have to be provided that the male plug-in part
28 is arranged on the additional buckle body 24 and the female
plug-in part 29 is arranged on the buckle body 1. A reverse
arrangement is also definitely possible. In summary, it is also
noted that in the second embodiment, both the buckle body 1 and
also the additional buckle body 24 are constructed as components
shaped from sheet metal or plates. In this way, the buckles
according to the invention can be produced simply and economically.
In particular, metal sheets can also be processed that are
subsequently not to be hardened, as is the case, e.g., in
water-resistant steels. Through the cold forming occurring during
the bending of the sheets, a corresponding hardening process is
achieved just during the bending. In conclusion, however, it should
be noted that the invention naturally can be implemented not only
in the form of buckle bodies made from bent plates.
