Description

The invention relates to a tilting device for furniture with a tiltable about a horizontal pivot axis Furniture part, in particular for work desks with inclinable Worktop, for supporting the furniture part in the respective skew, by having a longitudinal shape exhibiting Support member for supporting the tiltable furniture part has, with tilting play a clamping element reaches through, the pivoting in the extent of tilting game is, such that the support member under automatic suspension the canting with the clamping element extendable and in opposite Direction by automatic tilting with the Clamping element is secured, with a user-operable Actuating device for pivoting the clamping element is present in the sense of lifting the tilt.

Inclination devices are in great variety, such as from EP 0 699 404 B1, known. They are special for work desks, for example in the form of Desks thought to include the countertop can tilt to give the user a more comfortable working to enable.

These skewers consist of relatively many parts and are therefore consuming in the production.

A lower-part inclination device according to the preamble of claim 1 is known from DE 91 11 454 U. It extends the otherwise unguided support part by a the clamping part forming eyelet, which by means of a cable around a stationary pivot axis is pivotable.

A similar tilting device is shown in FIGS and 2 DE 44 03 534 A. In this case, that runs otherwise also unguided support part arcuate and extends followed by the attacked by him Clamping element in a stand of the table.

The present invention is based on the object, a in construction simple and inexpensive to manufacture To provide tilting device.

This object is achieved in that the Inclination device to be attached to the furniture body, Having longitudinal shape exhibiting guide part, wherein the Support member is guided telescopically in the guide part and off projecting the guide member and the clamping member against the guide member is supported, and that one when taking off the Supporting part ineffective and at the opposite insertion of the support member in the guide member, the movement of the support member braking braking device is present.

The tilting device according to the invention consists, sees one of the actuator and the braking device in principle, only from the guide part, the support part and the clamping element, so that a low-part arrangement is present.

When pulling out the example, the worktop of a Tables supporting support member from the guide part needs the actuator not to be operated. Therefore is it sufficient, for example, in the case of the worktop of a table, the worktop underneath the one connected to it Lift support member. If you leave the countertop in the desired inclination going on, the cant occurs immediately one, leaving the support part and with this the worktop stops by itself. To lower the worktop you press the actuator that the Clamping pivoted so that the support member released and can enter the management section.

Thus, there is also a simple handling.

FIG. 1 diagrammatically shows a work table in the form of a desk intended especially for young people, whose worktop 2 can be tilted from a horizontal starting position indicated by the dot-dash line, so that it rises from the user's back towards the top. In Figure 1, such an inclination of the worktop 2 is shown in solid lines.

The worktop 2 is in the area of the user facing front to one on the table carcass 5 in horizontal Direction in the longitudinal direction of the table extending pivot axis 3 swiveling and thus tilted. Further back engages on the underside of the worktop 2 a tilting device 4 on, the worktop 2 in the respective Inclination stops. In their horizontal starting position can the worktop 2 on a on the table carcass. 5 arranged stop 6 sit.

The tilting device 4 has a longitudinal shape having guide part 7 and a telescopically in the guide part 7 Guided, also longitudinal shape exhibiting Support member 8, which together form a telescopic arrangement. This telescope assembly is arranged high, wherein it can be inclined, as shown. The telescope arrangement is with its guide part 7, for example with the the guide member 8 opposite guide part end 9, on Table carcass 5 fastens and supports with its top out of the Guide member 7 projecting support member 8, and thereby with the Support part end 10, the table top 2 off.

The support member 8 and the support member 8 receiving Longitudinal recess 11 of the guide part 7 have a rectangular or square cross section, so that the Support member 8 is guided non-rotatably. In the embodiment Also, the outer periphery of the guide member 7 is rectangular or square.

The support member 8 has such a length that it in the largest skew angle of the worktop 2 still sufficient far into the guide member 7 engages that a safer Cohesion is present. Accordingly far that must Support member 8 in the horizontal starting position of the worktop 2 immerse in the guide part 7.

The table top 2 supporting support member end 10 is a attached to the table top 2, only schematically indicated Assigned carriage element 12, on which the support member 8 in Depth direction 13 of the worktop 2, that is rectangular to the pivot axis 3, is slidably mounted.

When pivoting the table top 2, the support member 8 either pulled out of the guide member 7 or in the Guide part 7 inserted. Thus, the support member 8 in the respectively desired inclined position of the worktop 2 corresponding Holds longitudinal position, the support member 8 engages Clamping element 14, wherein the penetrated by the support member passage opening 15 in cross section slightly larger than the support member 8, so that the clamping element 14 with tilting play sits on the support member 8. In this way, the clamping element 14 on the support member 8 by a certain pivot angle be pivoted back and forth.

The worktop 2 rests on the support member 8 and exercises this one force in the sense of insertion into the guide part 7 off. However, the support member 8 canted in the passage opening 15 of the clamping element 14, which is on the one hand the support member 8 at the point 16 on the guide part 7 is supported and the support point 16 down is pivoted, making it oblique to the longitudinal direction of the telescope assembly 7.8 is aligned. Thus, the support member 8 and over this the worktop 2 in the respective height held.

So that you move the support member 8 and thus the Slope of the worktop 2 can change, the canting must lifted between the clamping element 14 and the support member 8 become. This occurs when the worktop is raised 2, when the support member 8 is pulled out of the guide member 7 becomes, automatically. Already with a small takeover of the clamping element 14 in the pull-out, when it comes to the Support point 16 pivots upward, which is in the longitudinal direction the projection 8 seen projection of the passage opening 15 so large that the support member 8 practically unhindered can be moved. If the support member 8, however, in the Guide part 7 are inserted, the tilting means a user-operable actuator 17 lifted, with the clamping member 14 to the support point 16 is pivoted.

The clamping element 14 is based, as already mentioned, on the one hand of the support member 8 at the support point 16 against the guide member. 7 from. The actuator 17 engages the other side of the support member 8 on the clamping element 14 at. The support of the Clamping elements 14 on the guide part 7 takes place on its end face, as can be seen from the drawing. It is the End face 18 of the guide part 7, on which the support part. 8 exits, from the support point 16 to the actuator 17 beveled, in the direction of the worktop 2 supporting end 10 of the support member 8 away, so that in side view between the clamping element 14 and the guide member end face 18 a wedge-like gap results.

The clamping element 14 is expediently a sheet metal part, in which the passage opening 15 can be punched.

The actuating device 17, with which the clamping element 14th be lifted on one side in the direction of the guide part 7 away can, is opposite to one of a spring device 19 exercised Spring force actuated, the actuator in the unactuated state in a clamping element 14 is not holding ineffective position.

The actuating device 17 has an actuating rod 20 that can be grasped by the user. In the embodiment this actuating rod 20 extends from Area of the clamping element 14 from below the worktop 2 to the user facing the front of the work table 2 out. On the clamping element 14 facing end portion of the actuating rod 20 is arranged an actuating element 21, which is inoperative with unconfirmed actuator rod 20 and upon actuation of the actuating rod 20 on the clamping element 14 engages and this in the sense of lifting the tilt pivoted. This situation is shown in Figs. 5-7.

The actuating rod 20 is suitably in linear Direction, that is, in its longitudinal direction, guided so that the user has to move it in the longitudinal direction. In the embodiment the actuating rod 20 in the direction of Clamping element 14 are pulled away, so that the tilted repealed becomes. The linear movement of the actuating rod 20 is via an inclined surface arrangement in the pivoting movement implemented the clamping element 14. For this, this has the clamping element 14 a far under engaging actuator 21 a the clamping element 14 facing, inclined to Longitudinal direction of the moving rod 20 extending inclined surface 22 on when pulling on the actuating rod 20 to a to her inclined inclined portion 23 of the clamping member 14 to the plant passes and this pivots.

Instead of a linearly displaceable actuating rod could the operation also by means of a pivot lever or the like respectively.

If you want to pan the worktop 2 down, must, as explained, the actuator 17 are actuated. is reaches the desired new pivot position, the actuator let go, so that the spring device 19 the actuator 17 is transferred to its inoperative position and the clamping element 14 comes free, so that the Support member 8 automatically tilted again.

The clamping element 14, the facing end of the Guide part 7 with the protruding from him area of the Support member 8 and the clamping element 14 facing area the actuator 17 are in a device housing 24 housed and thus not visible from the outside. The guide member 7, the support member 8 and the operating rod 20 are guided by the housing wall to the outside. In The drawing is one of the two halves of the device housing 24 away to see the parts contained in it close. The linear guide of the actuator 17 takes place inside the device housing 24, for example by placing this on at least one of its side walls corresponding guide groove 25, in which a on the actuating element 21 arranged guide member 26 engages, the be formed by a still to be described web section can.

When you press the actuator 17 comes Support part 8 free, so that you can see no further measures before, the worktop 2 when lowering with the Need to hold hands. To avoid this is shown in the Inclining device a braking device 27 is present, when pulling out the support member 8 from the guide member 7 ineffective and the opposite insertion of the support member 8 in the guide member 7 is effective and the Movement of the support member 8 brakes.

The arrangement is suitably made such that the actuator 17 simultaneously with the operation the clamping element 14 and the braking device 27 is actuated, so that it becomes effective. The braking device 27 is a Friction brake and has in the embodiment two - in principle one would suffice - one another with respect to the support part 8 opposite brake body 28,29 on, each in one of the guide member 7 from the outside to the support member 8 passing through Recess 30 of the guide part 7 are mounted. When operating the actuator 17 engages this not only on the clamping element 14 but also presses the Bremsköper 28,29 against the support member 8, so that at this one Frictional force occurs. The Bremsköper 28,29 exist for example made of rubbery friction material.

The brake body 28,29 could in principle by the Actuator 17 are applied directly. It is more appropriate, however, that the actuator 17 via a likewise in the respective recess 30th mounted and out of this slightly protruding rolling elements 31 acts on the Bremsköper 28,29.

The two Bremsköper 28,29 are, as mentioned, on both sides of the support member 8 laterally arranged on the guide member 7. Accordingly this also forms the braking device 27 actuated Actuator 21 on the side of each brake body 28,29 one on the guide part 7 passing web section 32,33, at the one acting against the respective rolling elements 31 Sloping surface 34 is formed. If you move the operating rod 20 together with the actuating element 21 in the Drawing to the right, so that the clamping element 14 in his Ineffective situation is pivoted, arrive at the same time two inclined surfaces 34 to the rolling elements 31, so that these pressed inward to the support member 8. At unacknowledged Actuator 17, the inclined surfaces 34 at a distance arranged to the rolling elements 31 so that they do not be charged and thus the brake body 28,29 not after press inside.

The two functions of the actuator 21 (actuation the clamping element 14 and actuation of the braking device 27) are two in the direction of movement of the actuating rod 20 in a row Assigned arranged areas of the actuator. In this case, the actuating element 21 forms on the one hand a guide member 7 with the actuating movement of the actuator permitting movement play encompassing Frame 35, on which the inclined surfaces 34 are arranged, and on the other hand, against the clamping element 14 and actuating part 36 acting against its oblique portion 23, attached to the actuating rod 20 back to the frame 35 is. The frame 35 in principle does not have to be circumferentially formed but could also be formed by a U-shaped bracket become.

Above was the use of the tilt device for a Described working table. Of course kann.die Inclination device, however, also with other pieces of furniture are used, which have a tiltable furniture part.
