Definitions
- the present invention relates to height adjustable columns for furniture, especially for tables.
- An optimized height adjustment of an office desk, for example, is one of the basic requirements for the manufacturer in order to enable the user to work ergonomically.
- This table legs are provided, which allow to adjust the table height individually.
- the height-adjustable table legs are known to be made of a multi-part, for example, a three- or two-part column, the latter consisting of an inner column and an outer column, which are telescopic and can be pushed into each other or pulled apart.
- a multi-part for example, a three- or two-part column, the latter consisting of an inner column and an outer column, which are telescopic and can be pushed into each other or pulled apart.
- External column can be firmly connected to a substructure and forms a static unit.
- the inner column can with the
- a securing means Before the actual height adjustment of the furniture column often a securing means must be operated. Such securing means prevent the placing or removal of heavy objects on or from the furniture leading to an undesired height adjustment of the furniture column. Since the above-mentioned height-adjustable furniture, especially tables, sometimes have to carry high loads, it can happen that it comes even with the Entêtn itself to a sudden snapping down the movable portion of the height-adjustable table, which Damage to the table or the objects stored on it and, above all, injury to the user.
- the locking device allows a height adjustment of the furniture column namely only if in a first step, a corresponding actuating element is actuated, resulting in unlocking the locking device and in a second step, the movable portion of the table by the user, for example, by slightly lifting the table top, is relieved, whereby the locking device is unlocked.
- the latching means according to the invention can snap out of a latching element with the aid of an elastic element, and height adjustment of the table becomes possible.
- a height-adjustable telescopic column having an inner column and an outer column, wherein preferably within at least one inner column, a locking device is provided.
- This locking device may be provided in the form of a separate assembly within the column and is coupled in this case via at least one connection point with the inner column.
- a part of at least one of the furniture columns, for example the inner column acts as an element of the locking device.
- the locking device is actuated in a suitable manner via an actuating element, for example by an actuating handle or a push button, which can be arranged directly on the locking device.
- an actuating element for example by an actuating handle or a push button, which can be arranged directly on the locking device.
- actuating element on the table top or on the table frame, wherein the locking device can then be actuated, for example, via a cable pull mechanism, such as a Bowden cable.
- the locking device can be provided in only one furniture column.
- the locking device in a plurality of furniture columns, in which case the respective devices can be operated via only one common central switch, and furthermore can be coupled to one another via suitable synchronization devices, such as pull bands or a synchronization shaft, in order to let the unlocking and locking of the devices thereby synchronously.
- suitable coupling of the locking device - which can also be provided separately or detached from the furniture column - with the synchronization device of the locking directly on the corresponding synchronization element (such as the shaft or the drawstrings).
- Unlock the locking device manually that is, for example, done by gently lifting the table top.

- Fig. 3d shows an enlarged detail of the inventive locking device in a locked
- Fig. 1 shows a two-part height-adjustable telescopic column, consisting of an inner column la and an outer column lb.
- the inner column la has on its upper side a cover plate to which a table top can be attached.
- the inner column la is also open at the bottom and hollow (not shown).
- the outer column lb is also hollow and can thereby accommodate the inner column la.
- a locking device is disposed within the inner column la, which has at its upper end an actuating element 3 in the form of an actuating handle, which in turn protrudes from an upper end of the inner column la.
- the locking device itself which is shown in Fig. 2, consists essentially of a shift lever 4, on which the operating handle 3 at the upper end of the shift lever 4th is trained.
- the actuating handle points in the direction of the outer edge of the table.
- the locking device 2 comprises a locking element 5, which has a plurality of locking recesses.
- the locking recesses are shown in detail in FIGS. 3b to 3e.
- the shift lever 4 and the latching element 5 are partially covered by a slide guide 6b.
- a connection plate 8 for the outer column lb is also a connection plate 8 for the outer column lb provided.
- the locking device 2 On an opposite side of the slide guide 6b, the locking device 2 has a carriage 6. Furthermore, two attachment points 7 for the inner column 1a are arranged on the carriage 6. About these connection points 7, the table weight acts on the carriage. 6
- FIGS. 3 a to 3 e each show a section of the locking device in an enlarged view, which is identified by a circle in FIG. 3.
- Figures 3b and 3c also show a representation in which the hidden edges of the device are indicated by dashed lines.
- the corresponding section is shown without slide 6 and without slide guide 6b.
- a latching means is provided, which in this exemplary embodiment is designed as a locking pin 9, which can be seen in FIG. 3b.
- the locking pin 9 In a locked position of the locking device, the locking pin 9 is held in one of the locking recesses 5a.
- the locking recesses are in a pre- agreed angles inclined to the horizontal downwards. This special shape of the locking recesses 5a causes a clamping mechanism between the locking pin 9 and the slot 6a, in which the locking pin 9 is guided.
- a spring 10 tries to push the locking pin 9 out of the locking recess 5a. However, this is blocked by the shift lever 4. In addition, the table weight presses over the edges of the slot 6a on the locking pin. 9
- the locking pin 9 is pressed by the tapered surface on the recess 4a of the shift lever 4 back into the locking recess 5a.
- the release of the table top then pulls a burden on the locking mandrel 9 by itself, whereby the locking pin snaps into the locking recess 5a and the locking device is secured.
- an additional elastic element at one end of the shift lever 4, which brings the shift lever 4 on the mere release of the operating handle 3 in a locked position of the locking device.
- a tension spring may be provided at the lower end of the shift lever, which the Shift lever 4 pulls down after releasing the handle 3 and thereby causes the return and locking of the locking pin 9 in a locking recess 5a. The release of the table top and the associated burden of the carriage 6 then cause the securing of the locking device.
- the locking device according to the invention also ensures an accidental release of the tabletop automatic locking of the locking mandrel 9 in the next possible locking recess 5a, whereby an uncontrolled snapping down of the movable portion of the furniture is prevented.
