Abstract

The device (51) has a transmission and coupling device adjustable by a primary transmission device (131) during operation of an operating device (15), such that a secondary transmission device (133) and an adjusting device are adjustable. The coupling device is adjusted during operation of one of attachment-decoupling devices, while another decoupling device acts together with the coupling device in such a manner that the coupling device allows another primary transmission device (131a) and/or another operating device (15a) to be positionally-immovable. An independent claim is also included for an adjusting device comprising a coupling device.

Description

The invention relates to a coupling device, in particular for a furniture adjusting device according to the preamble of claim 1.

An adjustable furniture is for example from the EP 0 572 770 B1 as well as the EP 1 159 887 B1 known. In both Vorveröffentlichungen a folding table has been described, which includes frontally arranged T-shaped feet, what a work or table top is held. This table top is usually aligned horizontally in a working and use position.

This work or table top can be pivoted between its usual, more horizontal working and use position in a more vertical storage position.

As an adjusting a locking mechanism is provided for this purpose, the work plate in its usual, rather horizontal position of use fixed. In contrast, if the worktop is to be pivoted into a space-saving storage position, the locking mechanism is actuated, so that the plate can be pivoted about a horizontal pivot axis into its rather horizontal stowed position.

The locking mechanism can be triggered for example via an actuating device which is arranged on the underside of the table top directly adjacent to the longitudinal edge. If the table top, for example, to pivot about a horizontal pivot axis in both directions, so that the table top can be pivoted at any time in their stowed position, regardless of which side a user approaches the table, offers, adjacent to both sides of the table top on each the bottom to provide an actuating and triggering device, about which the locking mechanism can be released.

A generic coupling device is known from DE 20 2006 013 998 U1 known. In this prior publication, a height-adjustable table is described with feet provided on the opposite end faces. Between the frontally provided feet an actuator 5 is provided in each case below the table top, which is designed as extending along the table rod. The actuator extending from each end foot construction to the center of the table below the table top is connected to one another in the middle of the table by a coupling. By this adjustment ultimately a slightly height-adjustable table should be created, such that upon actuation one of the actuators the simultaneous entrainment of the other actuator is effected and thus provided corresponding axle bolts can be adjusted in the same direction. As a result, an adequate and identical change of the inclination of the two feet and thus a corresponding positioning of the table top to be made possible in a simple manner.

The object of the invention is to provide an improved adjustment especially for an adjustable furniture.

The object is achieved by a coupling device according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

In the context of the invention, a coupling device for the adjustment of furniture or furniture parts, in particular a locking and releasing device for pivotable tabletops is provided which may comprise a plurality of actuators, for example two actuators. In particular, for a pivotable table top are on the underside of the table top in each case adjacent to the longitudinal side of the table top, at least one respective actuating device for unlocking the table top provided, which can be tightened, for example, against the force of a spring device in triggering and release position. As a result, the locking device is ultimately adjusted in the release position, so that the table top can be pivoted, for example, from their usual, usually horizontal use position in a more vertical stowed position.

In the context of the invention but now a coupling device between the at least two actuators and the locking device is provided, which ensures that upon actuation of an actuation and release device not provided on the opposite table top underside adjacent to the longitudinal edge further actuating and triggering device not moved or adjusted becomes.

For this purpose, in the context of the invention, the coupling device is constructed so that when adjusting only one actuator of at least two provided actuators always only caused by the one actuator adjustment over the coupling device according to the invention to the at least one or preferably two furniture adjustment preferably in the form of a lock - Be released or release device, wherein the non-adjusted second actuator quasi decoupled remains in its initial position.

According to the invention, this can be realized in that upon actuation of one of the two actuating devices on the thus-adjusted, so-called primary transmission device, the coupling device is acted upon so that the leading of the coupling device to the at least one furniture adjustment secondary transfer device is adjusted with it and the from the other non-disguised actuator outgoing and leading to the coupling device further primary transmission device remains unaffected.

This principle can be realized in the context of the invention by different measures.

In a preferred embodiment of the invention, this is done by two carriages, which are coupled to one another via a transmission and coupling device effective between them. When an actuating and triggering device is actuated, a carriage is moved beyond the force of a spring device, e.g. longitudinally adjusted and above which e.g. secondary carriage acting on the same carriage, e.g. is connected to the adjustment or locking device of the table, with adjusted. Via the coupling device, the opposite second carriage is adjusted, for example, includes a driver Entkoppelungseinrichtung with such a long release path, so that ultimately the second primary transmission device is not adjusted (which therefore leads to the second actuator), but remains unchanged in its initial position ,

In FIG. 1a For example, the right end face 1a of a folding table 1 is shown. In FIG. 1b the right part of one longitudinal side 1b of the table 1 is reproduced with the carrying device 3 lying on the right in this illustration.

From the drawings it can be seen that the folding table 1 comprises an overhead table top 5 extending in the FIGS. 1a and 1b is located in their usually horizontally oriented working position.

In each case, the support means 3 is provided on the two opposite end faces 1a, which in the embodiment shown in each case comprises a support column 7, which merges into a support foot 9 at the bottom, which comprises support leg sections 9a and 9b projecting on both sides of the support column 7.

At the opposite ends of the support feet 9 each have a roller assembly 11 is provided, which is usually provided with a locking or release mechanism. As a result, the folding table can be pushed easily for any purpose or storage positions. In the respective desired working position can then be ensured by operating the integrated locking elements in the rollers that the table is not moved unintentionally.

In FIG. 2 is the in FIG. 1 shown shown right end face 1a of the table, in which the table top is brought to the right, vertically extending stowed position.

In FIG. 3a is different from FIG. 2 the tabletop 5 in the opposite pivoting position has been brought, in FIG. 3b in extracts, a rear view of the bottom 5b of folded in stowage position table top 5 according to the arrow III in FIG. 3a you can see.

To the worktop of each longitudinal side 1 b of the folding table 1 from a horizontal pivot axis 90 (FIG. FIG. 3b ) in stowed position, a triggering and / or actuating mechanism 15 is provided on both opposite longitudinal sides 1a of the folding table on the underside 5b of the table top 5 ( FIG. 3b ). If this triggering or actuating mechanism 15, for example, according to the arrow 15 'to the adjacent longitudinal edge 5d of the tabletop 5 tightened (namely, by grasping an associated handle portion of the actuator 15), a subsequently explained in more detail below locking mechanism is solved so that a working position located table top can then be folded in their pivoted by 90 ° storage position or vice versa. Out FIG. 3b It can be seen, for example, that two actuators 15a and 15b are provided, with one actuator adjacent to one longitudinal edge 5d and the other actuator adjacent to the opposite longitudinal edge 5d on the underside of the tabletop to allow access from either side. to take a corresponding actuator 15 and thereby perform the desired adjustment.

As is apparent from the drawings, on the bottom 5b of the table top 5 is offset in each case in the end face area of the end face 5c of the table top 5 inwards lying, a double-armed, in the embodiment shown parallel to the end face 5c of the table top 5 extending plate support 17 is provided, which is screwed for example by means of screws on the bottom 5b of the table top 5.

Between the two adjacent to the end edges 5c of the table top 5 arranged double-armed plate support 17 is a trough 19 attached to the underside of the table top, which serves as a cable channel 19 '.

The double-arm plate carrier 17 is - as in particular from the detailed spatial representation according to FIG. 4 results in - in a hollow shaft 17a, which at a predetermined distance 18 below the upper mounting plane 17d ( FIG. 1a ) of the double-arm plate carrier 17 is located, on which the underside of the table top 5 is placed and secured to the plate carrier. The above-mentioned distance 18 between the underside of the table top 5 and the central pivoting or tilting axis 90 (FIG. FIG. 3b ) is sufficiently dimensioned so that when pivoting the table top 5 in one of the two opposite stowed positions (in which the table top is oriented more or less vertically hanging) respectively on the support column-shaped stand device, so on the support columns 7, passes.

In this hollow shaft 17a engages an axis 21 ( FIG. 5 ), which is firmly anchored in an anchoring head 23, which in turn is indirectly supported on the upper end of the support column 7 at this.

This results in the possibility that the two-armed plate carrier 17 with the table top 5 can be pivoted together about the non-rotating axle 21 from its overhead, rather horizontal working position to its two opposite storage positions, in which the worktop more or less in Vertical direction is aligned.

The table top is at least in its one working position, usually in horizontal position, to be locked by means of an already mentioned locking mechanism so that a pivoting is reliably prevented.

The locking mechanism comprises for this purpose a furniture adjusting device 141, in the embodiment shown in the form of a locking and releasing device 143, which includes a pivotable locking and / or holding device 151 with a latching pin 147 and the other a latching device 153, the shown embodiment in the form of a locking disk 153 'is formed.

How out FIG. 5 it can be seen, the locking disc 153 'offset in the circumferential direction lying at least three locking recesses 156, 157 and 158, wherein the first recess 156 are arranged vertically upwardly position and the recesses 157, 158 in horizontal position diametrically opposite to the horizontally oriented axis 21 ,

In the illustrated embodiment, therefore, the locking disc 153 'is preferably screwed to the anchoring and holding head 23 and thus axially and above all radially immovable held. The mentioned circumferentially offset recesses 156, 157, 158 may, depending on the detent position of an axial latching pin 147 (FIG. FIG. 4 ), which is part of the actuator 141 or sits on it, are penetrated. The actuating device 141 with the locking and releasing device 143 and the latching pin 147 formed thereon or seated thereon, for example, can be held displaceably and / or pivotably in a recess 17 'of the double-arm plate carrier 17.

A coupling device 51 according to the invention for adjustable parts of furniture, for example for actuating a locking and releasing device 143 on a table with a pivotable tabletop 5, is shown schematically on the basis of the following figures.

It is in FIG. 6 a perspective arrangement of the coupling device with an adjusting housing 53 and a Verstellgehäuse-cover 54 and various incorporated within the housing adjustable elements shown in an exploded view.

Based on the following reproduced FIGS. 7 to 9 is the basic structure in addition to the exploded view according to FIG. 6 described.

It can be seen from the drawings that in the exemplary embodiment shown, the rupling device 51 comprises two adjusting carriages 55, ie 55a and 55b, which are offset transversely relative to one another and are oriented parallel to one another in the partially reproduced (shown in the opened state) in FIG. Each adjustment slide 55 is held biased by a spring device 57 in its one initial and home position, which it occupies when an actuator 15 is not tightened. The respective spring device 57a or 57b is supported, on the one hand, on a stop 58a or 58b fixed to the housing and, on the other, on a stop 60a or 60b moving with the respective adjusting carriage 55, and is prestressed under pressure.

As from the comparison between FIG. 7 and FIG. 8 A parallel slide 59 is provided in the region of each adjusting carriage 55a, 55b, which comprises a longitudinal recess 62a or 62b into which engages or protrudes a driver decoupling device 155a, this driver decoupling device 155a respectively formed on the associated adjusting slide 55a and 55b or attached to it. This driver decoupling means 155a and 155b has in the embodiment shown in plan view square shape.

The respective parallel slide 59a or 59b is longitudinally displaceably guided in the corresponding housing recess of the adjusting housing 53 and / or on the associated adjusting slide 55, taking into account the following special features.

Each of the two parallel slides 59 is provided on the mutually facing side with a tooth projection 63, so with ribs 63, wherein in the middle about a central axis 65 rotatably a transmission member 67 is arranged, which also externally on a partial circumference equipped with a tooth 69 is, with the one Tooth 69a with one toothed projection 63a is a parallel slide 59a and the other tooth projection 69b on the transmission member 67 with the other tooth projection 63b on the other parallel slide 59b is engaged, so meshes.

In FIG. 3b It has already been shown that a first and a second actuator 15a and 15b is provided, which is connected via a primary transmission means 131, for example in the form of a Bowden cable (or other suitable measure) with the coupling device 51. In other words, one actuator 15a is connected to the second primary transmitter 131b via the one primary transmitter 131a and the second actuator 15b at two different locations on the clutch.

It is according to the plan view FIGS. 7 and 8th It can be seen that the primary transmission device 131a coming from the one actuating element 15a, which leads to the one adjusting carriage 55a, leads via the associated input side 71a on the adjusting housing 51 to the one adjusting carriage 55a and is firmly anchored to a local anchoring point 155a. The second actuating device 15b is connected via the second transmission device 131b via the second input side 71b coming to the second Verstellschlitten 55b, namely at a second adjustment 155b, said anchoring points 155 form the so-called entrainment device 155 in the illustrated embodiment.

As from the others Figures 9 . 10 and 11 is apparent the coupling device 51, ie the parallel slide 55a and 55b connected via a further, ie secondary transmission device 133 with an associated furniture adjustment device 141, in the embodiment shown in the form of a locking and releasing device 143. It is from the other Figures 9 . 10 and 11 the coupling device 51 can be seen, at least with an actuating device 15a and the associated primary transmission device 131a, wherein the second primary transmission device 131b coming from the second actuating device 15b is only partially visible. At the mentioned, respectively opposite sides of the associated parallel slide 59a, 59b now engage the associated secondary transmission devices 133a and 133b, the once leading to the one end face of the adjustable table locking and release device 143 and a second, on the opposite end face of the table with the adjustable table top provided locking and releasing device 143 leads (where in the FIGS. 9 to 11 only the locking and releasing device 143 provided on an end face is shown or indicated).

In other words, therefore, the secondary transmission devices 133a and 133b are attached to fastening points 134a and 134b with the relevant associated parallel slide 59a or 59b.

The following is a closer look at the functionality.

If, for example, the one actuating device 15a is tightened on the underside of the table top adjacent to its own longitudinal side 5d as shown by the arrow 15 ', then is the associated transmission device 131a (here in the form of a Bowden cable - which of course also another power transmission and adjustment can be realized) also tightened, so that the associated Verstellschlitten 55a against the force of the spring means 57, 57a in the direction of its opposite adjustment positions in the adjustment 53rd , that is adjusted on its adjustment path 75a in the direction of arrow 175a ( FIG. 10 ). Since the driver 155a is formed on the adjusting slide, which projects through the aforementioned longitudinal recess 62a in the parallel slide 59a (wherein the driver 155a simultaneously represents the anchoring position 56a for the first actuating and triggering device 131a), the parallel slide 59a with the adjusting slide 55a thus also becomes from his in FIG. 9 shown starting position about his in FIG. 10 shown intermediate position to his in FIG. 11 adjusted end position adjusted. The entrainment of the parallel carriage is also because the driver 155a, the longitudinal recess 62a at the end of this longitudinal recess 62a projects and tensile stress on the aforementioned actuating and triggering device 131a directly against the limit stop of the longitudinal recess 60a and thereby the parallel slide 59a adjusted.

Since at the opposite end of the parallel carriage 59, the adjustment and transfer device 133a engages, leading to the one locking and releasing device 143 at the one end of the table, is about a locking mechanism (for example, a subsequently discussed locking lever) from its locking position according to the release position adjusted.

From the presentation FIGS. 9 to 10 However, it can also be seen that the displacement (ie displacement) of the parallel slide 59a via the tooth projections 63 formed on the inside also causes the transmission device 67 to rotate, which engages on its opposite side via the tooth engagement there with the further parallel slide 59b , Thus, the located on the opposite side second parallel slide 59b is also in his from FIG. 6 deviating, opposite position adjusted on its displacement 75b. Since at one end of this with parallel offset carriage 59b also the second secondary transfer device 133b attacks, leading to the second release and locking device 143 (which at the in the FIGS. 9 to 11 shown front side of the table is provided for unlocking and pivoting the table top), is pivoted both by tightening on an actuating element 15a both provided on the two opposite end faces of the table locking and releasing devices 143 in the release position.

In this mode of operation, however, despite the adjustment of the second parallel slide 59b, the second adjusting slide 55b has been held immovable due to the force of the spring device 57b acting on it. This is also because the slot opening 62b in the second parallel slide 59b is dimensioned so long that the projecting decoupling device 155b projecting through this slot opening 59b can dive into this slot without interference with the end-side delimitation of the elongated hole and can remain immovably in its initial position. Thus, the over the second adjustment slide 55b has been connected to the second actuator 15b primary transmission device 131b and thus the associated actuator 15, 15b itself also not adjusted.

If the mentioned first actuating device 15a is released again, the spring device 57a, for example, which pressurizes the first adjusting carriage 55a (for example also via a further spring device 146 provided in the respective locking device and later mentioned), returns to its in FIG. 9 shifted back home position shown. In addition, the transmission device 67 is pivoted back and the second parallel slide 59b also returned at immovable adjustment slide 55b to its original position.

If, for example, the second actuating device 15b were actuated, this would be indicated by - starting from FIG. 9 - now the in FIG. 9 Parallel slide 59b lying on the left and also the parallel slide 59b are displaced into the opposite adjustment position via the driver 155b. In addition, the second secondary transmission device 133b is also attracted directly and adjusts the locking and release device 143 connected thereto in the release position. About the mentioned transmission means 67 and the meshing with the first parallel slide 59a but also the first parallel slide 59a (now at unmoved first Verstellschlitten 55a) adjusted to its attractive position, wherein it attracts associated with this parallel slide secondary transmission device 133a with that to the first locking - and release device 143 leads and this adjusted in release position.

The advantage of this arrangement is always that when you tighten an actuator, the other actuator 15 is always decoupled, so it is not automatically adjusted.

For example, if only a single operating device for furniture, for example only one locking and releasing device 143 is provided, only one adjusting transmission device 133 would apply to the aforementioned adjusting device 51, which is connected, for example, either to the first parallel slide 59a or to the second parallel slide 59b.

In the following, one of a plurality of possible locking and releasing devices 143 will be briefly explained with reference to the drawings.

Like from the FIGS. 9 to 11 can be seen, the locking and releasing device 143 includes, for example, a locking lever 145 which is pivotable about an axis 144 and thereby comprises a locking pin 147, which in a fixed recess, for example 156 (FIG. FIG. 5 ) engages, and acted upon by the force of the already mentioned spring means 146th

In the illustrated embodiment, a lever translation is still provided, ie a second smaller sized locking lever 143 'is pivotally connected to another pivot axis 144' in the region of the free end of the first locking lever 145, said at this second locking lever 143 'then mentioned Adjustment and transmission device 133 attaches, which is connected to a respective associated first or second parallel slide 59a, 59b. If, as mentioned, the adjustment 51 adjusted accordingly by actuation of an actuator, the two aforementioned Verstell transmission devices 133a, 133b attracted and about the two locking lever, the associated locking pin 147 pushed out of the respective recesses so that then the table top support 17 with the associated table top 5 is freely pivotable about a horizontal axis 90, for example, in its more vertically aligned storage position. When the actuating device is released again, the respective latching pin is inserted again into a latching recess via the spring devices 57 in the adjusting device 51, but also via the additional spring devices 146 in the locking and release levers 143, if, with appropriate expansion of the tabletop (in horizontal or vertical position) for example, in the vertical direction) in the immediate extension of this locking pin 147 is located.

Based on FIGS. 12 and 13 will be discussed on another simplified schematic diagram for an adjusting device according to the invention.

From the basic illustration according to FIG. 12 It can be seen that here again a transmission device 67, for example in the form of a pivotable about a central axis 65 transmission device 67 is provided, which is hereinafter also partially referred to as a coupling device 167. From this coupling device 167 set at two opposite points to the central axis 65th each one of the two adjusting and transmitting devices 133a and 133b, which lead to the respective locking and releasing device 143, is displaced.

For example, if now the above shown, to the one actuator 15a leading transfer device 131a tightened, the double lever type transmission and coupling device 67, 167 counterclockwise from the in FIG. 12 shown position in the in FIG. 13 rotated position shown. As a result, both the secondary transmission devices 133a and 133b leading to the locking and releasing devices 143 are also taken along and tightened, since these adjusting and transmission devices are firmly connected to the transmission and coupling device 67, 167 at the fastening points 134a and 134b.

Preferably, in each case a respective carrier 155 or the respective transfer device 131 is still subjected to a force from one of the mentioned spring devices 57a or 57b (depending on the support point in the tension or compression direction, wherein in the assignment according to FIG FIGS. 12 and 13 the spring devices are biased to train), so that when released actuator 15, this spring device, the entire adjusting device 51 back into their in FIG. 12 pivots back home position shown.

In the illustrated adjustment triggered by the actuated actuator 15a but is in the representation in the transition from FIG. 12 to FIG. 13 it can be seen that although the driver 155, 155a (which is attracted by the actuator 15a) the Although transmission and coupling device 67, 167 pivoted accordingly, but at the same time the opposite driver 155, 155b is held by its spring means 57b further in its initial position, since the opposite driver 155b is simultaneously decoupled from the twisted transmission and coupling device 67, 167. In other words, the construction is such that, when the respective transmission device 131a, 131b is adjusted, the transmission and coupling device 67, 167 is rotated in the counterclockwise direction, but that a rotation of the coupling device 67, 167 with the non-actuated transmission device 131a or 131b connected carrier 155 holds in its initial position shown unshifted, thus each unclaimed second transfer device 131 and thus the associated second actuator 15 remains in its initial position.

In other words, based on FIGS. 12 and 13 only simplified shown that when pulling load a deadweight effect exists insofar as the force introduced via the actuating and triggering device for pivoting the coupling device and thus the transmission means 67, 167 that this pivoting movement but the untriggered and misplaced transfer device 131 due to the there attaching Spring action and decoupling in its initial position - holds swung.

In that regard, in principle, further modifications are possible.

Should only a locking and release device 143 be triggered in this embodiment, only one of the two secondary transmitters 133a or 133b would be eliminated.

5. Coupling device according to claim 4, characterised in that on each of the two adjustment paths (75a, 75b), an adjustment slide (55; 55a, 55b) is adjustable along the adjustment path (75a, 75b) against the force of a spring device (57; 57a, 57b) and is provided with a catch decoupling device (155; 155a, 155b) in such a way that an adjustment of the adjustment slide (55; 55a, 55b) via the catch decoupling device (155; 155a, 155b) also adjusts the coupled parallel slide (59; 59a, 59b).
6. Coupling device according to claim 5, characterised in that the catch decoupling devices (155; 155a, 155b) are constructed in such a way that if only one actuation device (15; 15a, 15b) is actuated, causing adjustment of the associated adjustment and parallel slide (55, 55a, 55b; 59, 59a, 59b) and thereby causing adjustment of the transmission and coupling device (67, 167), then the second parallel slide (59; 59b, 59a) is also adjusted, whereas the adjustment slide (55; 55b, 55a) cooperating with this parallel slide (59; 59b, 59a) is held by the spring device (57; 57b, 57a) so as to remain in the starting position thereof.
7. Coupling device according to any one of claims 1 to 6, characterised in that the parallel slides (59; 59a, 59b) are provided on the inner sides thereof, which face one another, with a toothed extension or ribs (69) which interlock with corresponding teeth or ribs (69; 69a, 69b) on the outer circumference of the transmission and coupling device (67, 167).
8. Coupling device according to any one of claims 1 to 7, characterised in that in the respective adjustment slide (55; 55a, 55b) a catch decoupling device (155; 155a, 155b) penetrates or is immersed into a slit (62; 62a, 62b) and in doing so is positioned in such a way that the catch decoupling device (155; 155a, 155b) entrains the associated parallel slide (59; 59a, 59b) during the adjustment movement triggered via the actuation device (15; 15a, 15b), whereas an adjustment movement, introduced by the transmission and coupling device (67, 167), of the parallel slide (59; 59a, 59b) merely adjusts the parallel slide (59; 59a, 59b) relative to the adjustment slide (55; 55a, 55b), while the catch decoupling device (155; 155a, 155b) which is immersed into the slit (60; 60a, 60b) remains unadjusted.
