Description
FIELD OF THE INVENTION
[0001] The invention relates to a table with a table top and at
least one fold-in or fold-out table leg.
BACKGROUND OF THE INVENTION
[0002] A large number of table constructions are already known in
which a fold-down table leg is attached to the underside of a table
top.
[0003] It is quite generally known in the art to use and combine
tables and table systems for conferences, large meetings, major
parties and the like so that variable sizes and shapes of tables
can be achieved to meet the particular requirements. If the tables
are not required they can be stacked in a suitable manner to save
space. For this purpose it is known for table legs to be completely
removed from a table top or for a table to constructed so that it
folds up, with the table legs being disposed so as to fold down on
the underside of the table top.
[0004] A folding table with a table top and fold-down table legs
disposed below it can be seen for example from DE-OS 23 09 576. In
the connection region between the underside of the table top and
the upper end of each table leg a folding hinge is provided in each
case approximately in the manner of a hinge link with slot/hinge
pin connections. In this case, on a rectangular table two legs on
each of the narrow sides are connected to one another in pairs and
can be pivoted jointly.
[0005] Also in another table construction (according to DE 298 03
651) in each case two legs are firmly connected to one another by a
connecting element which is rotatably mounted on the underside of
the table top and constructed for example in the form of a tube, so
that they can be pivoted or folded as a unit and can be locked with
the aid of a latch mounted on the underside of the table top.
[0006] A table with a table top and at least one fold-in or
fold-out table leg which is retained on the table top is known from
U.S. Pat. No. 2,127,981 and U.S. Pat. No. 1,905,219. In the table,
the locking device is constructed in the form of a locking sleeve
formed by an end region of the table leg which is held so as to
slide relative to the hinge fitting between a released position and
a locked position.
SUMMARY OF THE INVENTION
[0007] The object of the invention is to provide a table in which
the table legs can fold in or out in a simple manner and can be
latched in the fold-out state.
[0008] This object is achieved according to the invention defined
by the attached claims.
[0009] The table consists of a table top and at least one fold-in
or fold-out table leg which is retained on the table top by means
of a hinge fitting, wherein the hinge fitting has a first hinge
part fixed on the table top and a second hinge part fixed on one
end of the table leg, the two hinge parts being hinged to one
another so as to carry out the folding movement, and furthermore a
locking device is provided for locking the table leg in the
fold-out state. In this case the locking device is constructed in
the form of a locking sleeve which is held so as to slide relative
to the hinge fitting between a release position and a locked
position.
[0010] In this case the locking sleeve is formed by one end of the
table leg and can be latched in the locked position by twisting in
the manner of a bayonet catch.
[0011] In a further embodiment a latching mechanism is provided
which latches the locking sleeve in the locked position. In this
case the latching mechanism can be constructed for example in the
manner of a bayonet catch.
[0012] In a variant the table is designed so that it can be stacked
with the legs folded in, whereby the end face of the first hinge
parts remote from the table top forms a support region. In this
case the end face advantageously has a slide element for protection
of the contact surface.
[0013] If a plurality of tables are set up to form a cohesive table
arrangement, it is advantageous not only to place individual tables
adjacent to one another but also to provide a so-called inset panel
between two tables. For this purpose the tables must have
connection devices for releasable connection of the table to the
inset panel.
[0014] In a preferred embodiment this connection device is provided
in the region of the first hinge part and consists of a bearing
element which is pivotable about an axis perpendicular to the table
top.

DETAILED DESCRIPTION OF THE INVENTION
[0029] The table shown in the drawings consists essentially of a
table top 1 and at least one fold-in or fold-out table leg 2 which
is retained on the table top 1 by means of a hinge fitting 3.
[0030] As can be seen in particular from FIGS. 2 to 8, the hinge
fitting 3 has a first hinge part 3.1 fixed on the table top 1 by
way of a mounting element 7 and a second hinge part 3.2 fixed on
one end of the table leg 2. In order to carry out the folding
movement, both hinge parts are hinge-connected to one another via a
pin 3.3 which extends parallel to the table top and forms a pivot
axis.
[0031] A locking device is also provided for locking the table leg
in the fold-out state. This locking device is constructed in the
form of a locking sleeve 2.1 which is held so as to slide relative
to the hinge fitting 3 between a released position (see FIG. 2) and
a locked position (see FIG. 5).
[0032] In the illustrated embodiment the locking sleeve is formed
by an end region of the tubular table leg.
[0033] As can be seen in particular from FIG. 5, the outer
peripheral surfaces of the first and second hinge parts 3.1 and 3.2
in the fold-out state of the table leg form a sliding surface for
the locking sleeve 2.1.
[0034] In the unlocked position according to FIGS. 2 and 8 the leg
2 can fold down in the direction of the arrow 4 around the pin
3.3.
[0035] The locking sleeve 2.1 has an inner peripheral groove 2.2.
into which a ring 5 made from spring steel is snapped, this ring
having three projections 5.1 protruding into the locking
sleeve.
[0036] In order to ensure that the locking sleeve 2.1 can slide
relative to the hinge parts 3.1 and 3.2, corresponding cut-outs are
provided which allow the locking sleeve 2.1 to slide in the axial
direction but prevent twisting between the released position and
the locked position.
[0037] In the illustrated embodiment the locking sleeve 2.1 can be
latched in the locked position so that, on the one hand, the
locking sleeve does not slide inadvertently into the released
position during lifting of the table and, on the other hand, the
locking sleeve 2.1 is held as free from play as possible on the
table top 1 in order to avoid wobbling of the erected table.
[0038] For this purpose a latching mechanism in the manner of a
bayonet catch is provided.
[0039] The latching mechanism consists of an annular groove
provided on the first hinge part 3.1, or in the illustrated
embodiment three annular groove segments 3.4, and of the
projections 5.1 from the ring 5 fixed on the locking sleeve 2.1
which come into engagement with the annular groove. In order to
latch the locking sleeve 2.1 it is twisted in the manner of a
bayonet catch in the locked position. The projections 5.1 are
thereby turned into the annular groove segments 3.4. The annular
groove segments 3.4 have oblique run-on surfaces 3.5 which come
into contact with the projections 5.1 so that the locking sleeve
2.1 and thus the table leg 2 is tightened against the first hinge
part 3.1. This results in a largely play-free coupling of the leg
which is folded out.
[0040] In order for the table legs which are folded in according to
FIGS. 11 and 12 to be fixed in this position to a sufficient
extent, catch means 8 which co-operate with the table top are
provided on the underside of the table top 1 for each table leg on
the end remote from the hinge fitting, these catch means being
illustrated in greater detail in FIGS. 9 and 10. For this purpose
clips 8.1 are provided in this region in the table top 1 and these
clips co-operate with means 8.2 of complementary construction
provided on the end of the table leg in such a way that on the one
hand the table leg is securely held but on the other hand it can be
easily released again.
[0041] Each table leg is advantageously provided with feet which
permit adaptation of the length of the table leg. In the
illustrated embodiment the complementary means 8.2 are formed by a
stopper which closes the leg 2 and has an axial internal thread
into which the foot 2.3 can be screwed by way of an external thread
2.4.
[0042] In the folded-in position the table legs can be fixed to the
table top as required either parallel to the outer edges of the
table tops or, as in the illustrated example according to FIG. 11,
turned slightly inwards. The variant shown in FIG. 11 is
particularly appropriate when the table legs 2 are too long to be
folded down parallel to the outer edges of the table top.
[0043] As FIG. 12 shows, the table is stackable with the table legs
folded in. In this case the end face 3.1.1 of the first hinge part
3.1 remote from the table top 1 forms a support region which is
provided with a slide element 9 to protect the contact surface.
Apart from the lowest table, the contact surface is formed in each
case by the table top 1 of the table previously put down. The slide
element is made for example from felt, so that scratching or damage
to the contact surface can be reliably avoided.
[0044] The embodiment illustrated in the drawings offers not only
the previously described possibility of folding the table legs in
or out, but also has a connecting device for releasable connection
of the table to an adjacent table element, for example an insert
panel.
[0045] The first hinge part 3.1, the connecting device and the
mounting plate 7 form a unit attached to the underside of the table
top 1. The connecting device has a bearing element 10 which is
pivotable about an axis 11 perpendicular to the table top 1.
According to FIG. 13 the bearing element 10 provides two bearing
arms 10.1 and 10.2 which are oriented at an angle to one another
and rigidly connected to one another, and as required one or both
of the bearing arms can be pivoted out over the table top 1. The
angle between the two rigidly connected bearing arms 10.1 and 10.2
can for example be 90.degree. or 135.degree.. In a preferred
embodiment the bearing element 10 can be latched in one or more
pivoted-out positions.
[0046] The bearing arms have bores 10.1.1 and 10.2.1 respectively
into which lugs provided on corresponding inset panels 1.1 and 1.2
respectively can be introduced for connection.
[0047] By simple pivoting out of the bearing elements 10, larger
table configurations can also be set up quickly and securely.
[0048] As can be seen in particular from FIGS. 2 and 5, the first
hinge part 3.1 is firmly connected to the mounting plate 7 by way
of a screw 12, whilst the bearing element 10 is pivotably mounted
on the mounting plate 7. The mounting plate 7 is in turn firmly
fixed on the underside of the table top 1.
[0049] The mounting plate 7, the hinge fitting 3 and the bearing
element 10 form a compact fitting which on the one hand facilitates
folding down of the table legs and on the other hand facilitates
the attachment of further table elements. Naturally, within the
scope of the invention constructions without the bearing element
which can be pivoted out are also conceivable. The first hinge part
1 is then either directly connected to the underside of the table
top 1 or is connected thereto by way of a mounting plate.
