Abstract

A table, in particular an office table, having a tabletop (2) and at least one support (4, 12) for supporting the tabletop (2) is proposed. The table has at least one leg (7) and a foot (8) and is adjustable in height. The supports (4, 12) supporting the tabletop (2) have bearing surfaces (3, 13) which are substantially parallel to the tabletop (2) and are adjoined, at an angle, by an inclined bar (5) which leads into the leg (7) from the side and/or from the top depending on the height adjustment. Adjoining the inclined bar (5) is a downwardly extending connecting-link profile (6) which on its outside has height markings (63). In addition, the connecting-link profile (6) has a manually releasable catch mechanism (46) capable of locking into associated catch points of a connecting-link guide (16) of the leg (7). <IMAGE>

Description

The invention relates to a table, in particular to an office table of the type according to the preamble of claim 1 and a table system consisting of such tables.

To set up a work space, for example an office, in which one or more tables are set up and adjusted according to their specific use, it is necessary to use tables of different heights. But even when moving or restructuring an office organization, when expanding or when introducing new work equipment such as IT equipment or the like, one or more tables often have to be adjusted to the respective requirements at short notice. This may be necessary several times in succession until the final setting has been found.

Tables are known which are adjustable in height. Different tools are required to adjust the height in order to loosen and dismantle individual connecting elements. Then the one or more table legs are pulled out or extended in another way and the connecting elements are attached and tightened again. This requires time and special care in order not to lose the generally very small connecting elements.
In linked office table systems that are often used today, the height adjustment either has to be dismantled one module at a time, adjusted in height and then re-attached to the other modules after the height adjustment, or the entire system has to be set aside or raised and temporarily supported for adjustment . This requires several auxiliary persons or the use of special devices. Cables or the like laid inside the tables or table modules either have to be laboriously disassembled for height adjustment, or it may be necessary to re-manufacture the respective cable ducts.

A scale is usually held next to the table to set the desired height. This requires an additional hand. Most of the tables mentioned do not have a favorable contact surface, which makes it possible to hold the table clearly with one hand and with the other hand to hold the table or one leg for the exact one desired when adjusting or adjusting the height, without the risk of injury due to pinching or pinching Adjust height.
There are also tables that have built-in height adjustment mechanisms. However, these are disproportionately expensive and, at the same time, are fragile and heavy due to their complex construction. All legs are shortened or lengthened at the same time, so that no consideration can be given to uneven floors.

It is an object of the invention to provide a height-adjustable table which is height-adjustable without the disadvantages of the prior art.

To solve this problem, a table according to claim 1 is proposed. With this table it is possible that a person can, for example, make a height adjustment all by himself. This person can safely and clearly grasp the table on the inclined rod, lift it up and hold it while using the other hand to release the locking device, adjust the length of the leg using the legible height marking and, after the locking device has been locked in, set the table back on the floor. This completes the height adjustment for a one-legged table. In the case of a multi-leg table or a system of several tables, the process is repeated with every additional leg. For this purpose, cables laid in the tables advantageously do not have to be dismantled, and in the case of a system comprising two or more tables, these cables must not be dismantled from one another.
Further advantageous exemplary embodiments of the invention result from the subclaims.

Figure 1 shows a table with a table top 2, here a Y-shaped support 4 and with a leg 6 and a foot 8. The support 4 used here is formed with two Y-shaped inclined rods 5, to which a here not visible backdrop profile 6 connects, which is hidden in the leg 7. The leg 7 stands on the foot 8, which is designed here as a plate foot. It can be clearly seen here due to the transparent table top shown that the oblique rod 5 of the support 4 is easy to reach for holding the table. The locking device 46 arranged for the height adjustment of the table cannot be seen in this illustration like the link profile 6.

FIG. 2 shows a rectangular table with two beams designed as cross beams 12, each of which is stuck in two legs 7 with its backdrop profiles. In this case, the legs are placed on feet 8, which have a diameter that is slightly larger than the leg diameter. The table top 2 shown transparently lies on the bearing surfaces 3. This is also followed by oblique rods 5, which merge into the backdrop profile 6, not shown here, which are hidden in the respective leg.

FIG. 3 shows a table system, composed of the tables from FIGS. 1 and 2, these tables being connected to one another by a table coupling 76. Via this table coupling 76, cables can be routed from one table to the other without hanging down too far between the tables, which is a risk of accidents. The cross members 12 are connected to one another by frames 18, the frames 18 also being suitable for carrying the table. The table coupling 76 is articulated in both tables, so that each table can be raised independently of the other and the height can be adjusted without the two tables having to be detached from each other beforehand. The table coupling 76 is explained in more detail later in FIG. 6.

A broken cross member 12 is shown in FIG. 4, which opens via its inclined rod 5 into the link profile 6, which is visible here by omitting parts of the leg 7. The leg 7 is shown here as a hollow profile which contains the link guide 16. The link profile 6 is inserted into the link guide 16 from above and held at the selected height with the aid of the latching device 46.

Figures 4 and 5 show this locking mechanism, once in perspective and once in section (Figure 5). The oblique rod 5, which opens into the link profile 6, adjoins the wing-shaped extension 13 of the support surface 3 in the case of the carrier 12. This is divided downwards into two mutually elastic profile sections, in which the latching device 46 is received. The bolt 48 is, see extending from top to bottom, rotatably mounted in an axis 47. At the upper end of the latch 48, a push button 54 is attached, which extends to the outside of the table from the link profile 6. At the lower other end of the bolt 48, a locking lug 49 is attached, which latches in the position 58 (shown hatched in FIG. 5) in the bore 58. FIG. 4 shows an intermediate position of the bolt 48 when the push button 54 is pressed. The locking lug 49 can be seen here somewhat above a bore 58. If button 54 in the illustration (shown in FIG. 5) is now pushed to the right, ie into the link profile, the bolt 48 rotates about the axis 47, so that the latch 49 from the opening 58 of the link guide inwards the link profile 16 occurs, and the bolt 48 is moved to the position 48 '. In this state, the leg 7 can be pulled down with its link guide 16 or only moved down a few holes to increase the table height. If the locking button 49 is again seated over a bore 58, the push button 54 can be released again, so that the locking lug 49 can snap into another bore 58 of the link guide 16. So that the bolt 48 is pushed into the locking position again and again, a spring 56 is arranged, which biases the bolt 48 so that the locking lug 49 is securely retained in a bore 58. A person carrying out the table height adjustment is preferably outside the table (this is on the left-hand side) and can read the height marking 63, which is applied approximately centrally and preferably raised on the backdrop profile, for this purpose, after which he can adjust the table height. The leg 7 with its slotted guide 16 is preferably made of extruded profile. As a result, the lightest possible table construction is achieved.

As can be seen in FIG. 4 in the upper part, part of the extruded profile of the leg 7 is released from the upper edge of the leg to the upper edge 66 in such a way that a profile recess 64 is formed. This profile recess 64 serves to allow the oblique rod 5 to "dip" into the leg 7. The bolt 48 has a bore 50 through which a screw 61 can pass. In Figure 5, the screw 61, which is screwed into the screw thread 60 of the left elastic profile section of the link profile 6, is shown. To secure the link profile 6 fixed with the latching device 46 in the link guide 16, the screw is screwed against the right-hand profile section, a wrench being able to extend through the bore 59 located here on the left-hand side in order to spread the two profile sections against one another place them from the inside outwards on the perforated surfaces of the link guide 16 and secure the link profile 6 in the link guide 16 by clamping. This backup is not necessary, but is advisable.

The right elastic profile section of the link profile 6 shown in FIG. 5 expediently has a taper designated by 65 in order to make the introduction of the link profile 6 into the link guide 16 easier during the initial assembly. FIG. 5 shows the upper edge of leg 7, which is covered from above with a cover 68, which can be snapped into the profile. Below this, in dashed line 6 ', can be seen where the highest position of the link profile 6 is. This shows that the dovetail-like guidance of the link profile 6 in the link guide 16 ensures stable guidance of the wearer in the leg at all times.

FIG. 6 shows in perspective a section of a table system with a rectangular table broken off to the right, to which a one-leg table with an essentially rectangular table top is connected via a table coupling 76. The shape of the table top is freely selectable. A good transition here is a cable which leads from the rectangular table out of a cable profile 30 suspended in the frame 18 and leads via the cross member 12 or corresponding openings therein to the plate 82 of the bridge 80 of the table coupling 76. The table coupling 76 is articulated via bearings 78 on the cross member 12 and on the table top 2 of the one-legged table. Also It can be seen here that the height of each of the two tables can be adjusted independently of the other without the table coupling 76 having to be released. The arrangement of the cable profile 30 in the frame 18 is described in more detail later in FIG. Because the plate 82 is placed on the articulated bridge 80 of the table coupling 76, it is freely selectable according to individual wishes how wide the plate 82 is designed for the cables to be guided. A width up to almost the table width is conceivable.

Figure 7 shows the part of the carrier 12 shown in Figure 4 from below and part of it from the side. Here again, the threaded bore 60 for the clamping screw 61 can be clearly seen, as well as the recess 53, which serves as a pivot bearing for the bolt 48 about the axis 47. As shown in FIG. 4, the latch 48 has lateral folds in order to keep it centered in the recesses 52 in the link profile 6. A spring collar 57 which extends the thread 60 is shown here, around which a trapezoidal spring 56 shown in FIG. 5 can center and hold in order to press the bolt against the opposite profile section. The wing-like extensions 13 of the support surface 3 have bores 15 here in order to be able to connect the cross member to the table top 2. FIG. 7 also shows the cavity 11 visible from below, as is only marked with a dashed line in FIG. 4. Cables or the like are preferably guided in this cavity 11. These cables run from the floor over the table base upwards and pass within the cavity 11 in the oblique rod 5 into the cavity 11 of the carrier 12. From there, the cables are led into cable profiles 30 to the center of the table or, as shown in FIG. 6, over Table couplings 76 passed to another table. Of course, these cavities can be closed from below with clip-on covers, so that there are no "flying" lines. The lower end of the link profile 6 is shown on the left side of FIG. 7 in the direction of arrow A. Here the height markings 63 can be seen, which can be seen from the link guide 16 in accordance with the length of the link profile 6.

FIG. 8 shows a profile which is preferably used and which can expediently be produced from an extruded aluminum profile. The recess 64 is indicated here, which, as also shown in FIG. 4, enables the inclined rod 5 to penetrate the leg 6. Furthermore, the profiling of the link guide 16, which is similar to a dovetail guide, can be seen.

Figure 9 now shows the profile of the leg 6 with clipped-in cable channels 32 and 34. These channels and the leg are shown here in section, but are not hatched for reasons of clarity. The profiles are preferably made of elastic plastic, which can also be color-coordinated for design reasons, and are used to guide thin and thick cables. As a rule, the cable duct 32 will be used, since it can keep the cable protected in the recess in the leg 7. In the event that a large number of cables or very thick cables have to be routed, the use of the cable channel 34 is appropriate. The plug-in profile 98 according to FIG. 10 is expediently used to fasten the feet, which correspond to round plates with upwardly projecting threaded screws. This is expediently pushed into the link guide 16 of the leg profile shown in FIGS. 8 and 9 and welded or glued in the suitable position in the leg profile. The bores 100, 101 and 102 are provided with threads into which screws can be screwed in from below. For a one-legged table, a foot is expediently screwed into the threads 100 and 102 with two screws. The thread 101 serves for a central fastening of a foot.

As can be seen from the description of the preceding figures, the profile of the leg 7 used here is a multifunctional profile which is capable of performing many tasks.

Figures 11 and 12 show the profile of the frame 18, which connects the beams 12 together. Various attachments are expediently attached to this frame 18. The frame 18 has receiving grooves 19, 21 in order to fasten attachments for fastening further components. A tab 22 is shown in FIG. 11, via which the table top 2 is fastened to the frame 18 by means of the screw 23 by engaging the tab in the upper receiving groove 19. A shoe 24 which is snapped in from the right in the approximately circular receiving groove 21, which is made of plastic material and is elastically worked out, is snapped in from the right in order to hold on to an angle 26 which is connected to the angle 26 by a dovetail-like guide. In the axis 25, a screw, similar to screw 23, is screwed through the angle 26 in order to fix the angle 26 to the table top 2. The angled part adjoining the attachment point 25, angled approximately 45 degrees, runs approximately parallel to the oblique rod 5 of the support 12 in the installed state in order to carry a panel 28 in the attachment point 27. While the angle 26 is only a slight one Has the longitudinal extent, the aperture 28 can extend over the entire table width. The aperture 28 shown broken off in FIG. 11 can of course protrude as far down as is required by individual wishes. This aperture 28 has a protective function. It is an advantage if the front of the table cannot be seen into the footwell of a table. Furthermore, it is advantageous if the person sitting at the table is protected from unfavorable air flow or unnecessary heat loss is prevented.
FIG. 12 shows the profile of the frame 18 with a cable profile 30 clipped into it. The clip mechanism can be seen in the X-high representation. The cable profile 30 is preferably made of elastic plastic material, so that a snapping of the head of the profile, as shown in detail in X, can be easily achieved. Detail Y shows the right angled side of cable section 30 with outwardly extending convex bumps which serve to achieve a pleasing surface structure. This is particularly advantageous if the cable profile 30, as in the present case, is produced in advance from plastic regenerate material, which contains slight color fluctuations. The loose hanging of the panels 28, as shown in FIG. 11, has the advantage that bumping against them with the foot or other objects does not lead to injuries in this relatively freely suspended part, since the panel 28 can deflect. As a rule, however, it is so far away from the footwell, which is located on the left of the panel 28 in FIG. 11, that such a collision is actually not to be feared. The cover is made in advance from plastic material.

FIG. 13 shows a table system which is composed of a round table and an angular table and is connected to a table coupling 76. To support the table top 2 of the angular table 4 frames 18 are used in addition to the cross member 12 and the Y-shaped carrier, which are connected via plug-in angles 20, the angle of which corresponds to the angle of the table top. These plug-in angles 20 are aluminum die-cast parts, which are designed in their outer contour so that they can be inserted into the inner profile of the frame 18. A screw connection or other fastening can be provided after insertion.

FIG. 14 shows a rectangular table with adapters 92 screwed onto the table top from below, which carry columns 94, on which in turn a console 96 is placed. By using these add-on parts, the present table system or each individual table can also be provided with a so-called third level, in which expediently additional tools, such as screens, folders or the like, can be arranged. Even when attaching such consoles for the third level, it is possible (of course with a cleared table) to adjust the table provided with a height adjustment according to the invention to an individually desired height. It is also easily possible due to the individually adjustable tables to bring the legs into different lengths if the stand area should make this necessary. The cable ducts 32 and 34 shown in FIG. 9 can also be designed such that they change their length accordingly when the table height changes. It is always guaranteed that no flying or loose cables hinder the trouble-free use of the tables or table systems. As can be seen in FIG. 13 using the example of the angular table, the table can optionally be carried on one side by a cross member 12 via two legs 7 and on the other side by a Y-shaped carrier 3 with one leg 7. This also includes easy to see that the distance between the parallel frames 18 is always the same, whether the frames are attached to a cross member 12 or to a Y-shaped support 3. This means that the angle table from FIG. 13 could also be arranged as a straight table, without a plug-in angle 20. The frames 18 could also run parallel in this case. Appropriately, the table tops can be attached at the designated point for a working device connected to a cable with openings which can be closed with relevant elastic covers, so that only one opening necessary for the cable or its diameter is created. The upper ends of the legs 7 are also expediently provided with snap-on lids, as shown in FIGS. 5 and 6. In order to achieve the lowest possible weight for all components, aluminum die casting should preferably be provided for the cross member 12 and the carrier 3. The legs 7 are expediently made of extruded aluminum profile, as are the frame profiles 18. Conveniently, all material which does not have to bear high load-bearing capacities, such as cable profiles 30, cable channels 32, 34 and the table coupling 76, is made of plastic.

The invention is not restricted to the embodiments described here.
