Office desk

The invention relates to an office work table with the features specified in the preamble of claim 1. Its at least one worktop is usually attached to a base frame and, if necessary, ^height -adjustable so that an optimal ergonomic adaptation to the user is provided.

Due to the introduction of new information and communication technologies as well as modern office machines such as memory sticks, word processing systems, personal computers or similar, an office desk must generally accommodate a large number of electrical devices that can be connected to the mains and, if necessary, interconnected. For practical, safety-related and, not least, aesthetic reasons, it is now necessary to be able to lay and cover these many connecting cables in an orderly manner. For this purpose, office desks must be equipped with state-of-the - art Technology already has so-called cable ducts,

which are arranged, for example, under the table top or in the rear edge area.

The latter, accessible from above, are in S usually by cover rails or a brush trim

closed to hide the inserted cables

_t . and to fix it. For the state of the art, see DE-GM

22 11 585, DE-GM 78 05 235 and DE-GM 80 03 714,

A disadvantage of the known cable duct designs is their low flexibility with regard to the ability to lead out the connecting cables to the individual electrical work devices, which are usually distributed across the table. In fact, the covered cable ducts are often only accessible from their side opening area or via a short, central flap in the cover. In addition, difficulties arise with the often bulky connecting plugs because the cable duct itself is too small and deep to accommodate or lead through them. With cable ducts that are dimensioned accordingly, the disadvantage is that a considerable amount of the work surface is lost.

Based on this, the invention is based on the object of creating an office work table which has a cable duct which only slightly affects the work surface, is cleanly covered but can be flexibly adapted to the respective local and connection requirements. This object is achieved according to the characterizing features of claim 1. Accordingly, the cable duct can be made very wide due to the virtually unlimited space available there and can be provided with high side walls due to its arrangement below the worktop, so that a large number of cables can be accommodated in it without any problem. The cable feed-through slot in the worktop makes it easily accessible from above, so cables leading to devices on the worktop do not have to be led past the back of the worktop onto the table surface. The cable feed-through slot itself is formed in a structurally simple manner by a side edge - in particular the rear edge - of the worktop and the insulating strip running parallel to this at a distance in the worktop.

Since the slot should only have a limited width after the cabling in order not to unnecessarily impair the work surface, measures are provided to widen it, for example to allow a bulky connector plug to be fed through during cabling. This is made possible by the table top and/or the strip being mounted at right angles to the slot. For example, the strip only needs to be moved backwards to achieve a significant widening of the cable feed-through slot. If both the table top and the strip are mounted so that they can be moved backwards, this has the advantage that the cable feed-through slot can be widened even if the strip cannot be moved backwards. This is the case, for example, if the table is flush against a wall or two tables are placed back to back. Here, the sliding bearing of the table top and bar according to the invention offers a high degree of flexibility when cabling the devices placed on the table.

According to the last characterizing part of claim 1, the cable feed-through slot is covered by a cover lip made of a soft elastic material that runs approximately in the plane of the plate surface and is attached to one side of the cable feed-through slot. The connection and connecting cables for the electrical work equipment on the desk that are inserted into the cable duct are therefore hidden in the cable duct over its entire length. At the corresponding locations for the work equipment, however, the cable can be pulled through the cable feed-through slot between the cover lip and the corresponding adjacent side edge. The cover lip itself is curved slightly upwards or downwards, but springs directly next to the

The cable exit point returns to the cover position located in the plane of the floor surface. Since the cable guided through the cable feed-through slot is subjected to the cover lip, it is additionally secured. The office work table according to the invention therefore enables the electrical connection and connecting cables to be flexibly guided through the cable feed-through slot both to the work area and to the cable duct on the underside of the table, thereby achieving particularly safety-related advantages with an aesthetically pleasing appearance.

In subclaims 2 to 10, advantageous embodiments of the subject matter of the invention are specified in a first embodiment. Claims 1 to 3 characterize a structurally simple structure of the table, with which the support of the table top or strip that can be moved at right angles to the slot is realized. The design of the guide rails as an L-angle profile represents a particularly simple, but stable support.

The design according to claim 4 allows the worktop to be moved at right angles to the plane of the worktop, but it can be fixed in any sliding position by means of the screw bolts on the guide rails. The sliding range is determined by the length of the elongated holes.

According to claim 5, the screw bolts are formed by knurled screws with knurled heads that act on the guide rails from below. This has the advantage that the fastening of the worktop to the guide rails can be released very easily and without special tools in order to remove the cable feedthrough.

slot by moving the worktop forwards. Since the knurled screws do not have to be completely unscrewed, but only loosened, the worktop is still held on the guide rails and cannot tip over or be pulled off the table frame. This is particularly important because the office worktable according to the invention is usually used to hold high-quality equipment. Because the heads of the knurled screws are arranged below the worktop, they are not visible and do not spoil the overall visual impression of the table. Arranging the heads on the work surface would also be disruptive when working.

By means of a design according to claim 6, the stability and guidance of the worktop on its guide rails is improved.

Claim 7 specifies a fixing for the strip that is analogous to the method of fastening the worktop, whereby according to claim 8 a screw bolt is arranged in each of the two end areas of the strip. To move the strip, it is therefore only necessary to unscrew the two screw bolts, which can also be designed as knurled screws that act on the guide rails from below, analogously to claim 5, from the threaded sleeves in the strip.

To ensure that the strip cannot be completely detached from the table, the guide bolts are provided according to claim 9. The strip is guided by means of these in guide holes in the back edge of the worktop across the slot direction over a limited displacement path. If desired, the strip can be removed completely. For this purpose, only the guide bolts of the strip have to be removed from the guide holes in the worktop.

of claim 13. The plate-shaped struts are provided in the area of their attachment to the worktop with a longitudinal slot running essentially at right angles to the strip, which is penetrated by a fixing part that engages the back of the worktop. This fixing part is, for example, a fixing screw. If the cable feed-through slot proves to be too narrow for a device plug or the like to pass through, this fixing screw only needs to be loosened, whereupon the strip can be moved backwards away from the worktop. If the cable feed-through slot is wide enough, the device plug can be inserted into the cable duct or passed through downwards.

A very simple method of fastening is specified in claim 14. The fixing screw is therefore a knurled screw/ which engages in a threaded sleeve embedded in the underside of the worktop. No tools or the like are therefore required to move the strip and thus adjust the width of the cable feed-through slot.

Claims 15 to 17 characterize advantageous further developments of the cover lip closing the cable feedthrough slot.

The reinforcing lip arranged below the cover lip and flanking it in parallel according to the characterizing part of claim 15 supports the cover lip in its spring-back property into the starting position. Since the reinforcing lip is attached to the same side of the cable feed-through slot as the cover lip, but ends at a distance from the opposite side of the cable feed-through slot, the smooth feed-through is

of connecting cables through the cable feedthrough slot is essentially not impaired (claim 16).

According to claim 17, the cover and reinforcement lips are formed in one piece with a connecting strip made of a soft elastic material that runs along their fastening side in the cable feedthrough slot. In cross-section, this integral component is therefore U-shaped, with the cover lip forming a short U-leg. The U-base represents the connecting strip, which is usually very narrow.

The strip on the back of the cable feed-through slot can also serve a covering function. To do this, it extends as a cover essentially vertically upwards and/or downwards over the top and/or bottom surface of the worktop, as stated in the characterizing part of claim 18. The part that protrudes upwards can therefore also serve as a rear stop, whereby devices or objects placed on the office desk are protected from being pushed over the back edge of the desk and thus from falling down.

An embodiment according to claim 19 is aesthetically very appealing, especially for free-standing office desks - for example in open-plan offices. The strip designed as a panel forms a continuous, flat rear wall with a rear privacy screen of the table when inserted. This means that the foot area of the office desk with its cables etc. leading downwards cannot be seen.

The characteristic of claim 20 describes a stable and robust fastening option for the panel-like strip. The rear ends of the struts are bent vertically and lie flat against the panel. The struts are therefore L-shaped in cross-section.

The invention is explained in more detail in an embodiment using the enclosed figures, which show:

The vertically arranged privacy screen 5 serves as a protection against the wind.

Below the worktop 1 is parallel to its Rear edge 7 between the two side walls

2 the cable duct 6 for accommodating various

Cables are arranged. The cable duct 6 is connected by a

formed by a sheet metal with a flat U-shaped cross-section, which can be covered by a cover strip 23. An elongated opening 24 is formed in the cover strip 23 (Fig. Ti), through which a socket strip additionally inserted in the cable duct 6 can be accessed.

The cable duct 6 is accessible from above through the cable feed-through slot 8 running parallel to the rear edge 7 in the worktop 1.

The left side of the cable feed-through slot 8 in relation to Fig. 1 is formed by the rear edge 7 of the worktop 1. Opposite, the cable feed-through slot 8 is delimited by a strip 9 that runs parallel and at a distance from the worktop 1 in the plane of the panel over the entire length of the rear edge 7. Connecting cables and the like can be pulled through the cable feed-through slot 8, which are fed in the cable duct 6 and are used to connect electrical devices on the worktop 1.

In a first embodiment according to Fig. 1-6, the strip 9 is attached to the worktop 1 with struts 10 distributed over the length of the strip below the worktop 1 (Fig. 2). These can also serve as cable supports for device connection and connecting cables (not shown) to be inserted into the cable feedthrough 8. Another essential feature of the invention

The object is the cover lip 11 running in the plane of the plate surface, which is on the side of the cable feed-through slot facing the strip 9

8 is attached. In the inserted position of the bar shown in solid lines in Fig. 1

9, the cover lip 11 covers the entire cable feedthrough slot 8 between the rear edge 7 and the strip 9. Since the cover lip 11 is made of soft elastic material, an electrical cable can be pushed through the gap 12 between the worktop 1 and the cover lip 11.

The strip 9 is rectangular in vertical section across its longitudinal direction and corresponds in its thickness to the worktop 1. On its underside, the strip 9 rests on the rectangular plate-shaped struts

10 and is screwed, glued or similar to them. The struts 10 themselves lie flat with their flat, horizontal surface area on the underside 13 of the worktop 1.

The extended position of the bar 9 shown in Fig. 1 by means of a dashed line is made possible by the design features of the struts 10 shown in detail in Figs. 3 and 4. In the area where they are fixed to the worktop 1, they are provided with a longitudinal slot 14 running essentially at right angles to the bar 9, which is opened by the knurled screw

15. This engages in a threaded sleeve embedded in the underside 13 of the worktop 1

16 If the cable feed-through slot 8 is to be widened and the strip 9 pulled out to the rear, only the knurled screws 15 fixing the struts 10 need to be loosened. Within the length of the longitudinal slot 14, any distance between the strip 9 and the rear edge 7 of the worktop 1 is possible.

adjustable and can be fixed by tightening the knurled screws 15.

In Fig. 3, next to the cover lip 11, a reinforcement lip 17 is shown below it, flanking it parallel to it. It is also made of soft elastic material. If the cover lip 11 is moved downwards from its rest position shown in the worktop plane, the reinforcement lip 1? creates a spring-back effect, through which the cover lip 11 is pushed in the direction of the starting position. This position is thus reached again more quickly, and cables passing through the gap 12 between the cover lip 11 and the rear edge 7 are subjected to a greater load and thus better fixed. The cover lip 11 is formed in one piece with the reinforcement lip 17, with a connecting strip 18 running along the strip 9 being provided between them. The structural unit is thus U-shaped in vertical section across the cable feedthrough slot 8 (Fig. 3), with the long U-leg being formed by the cover lip 11, the short U-leg by the reinforcing lip 17 and the U-base by the short connecting strip 18.

In Fig. 5 and 6, advantageous further developments of the subject matter of the invention are shown in its first embodiment with panel-like strips 9. These extend vertically downwards (Fig. 5) and also upwards (Fig. 6) beyond the bottom and surface of the worktop 1. In the inserted position (Fig. 5 and 6), the rear surfaces 20 of the panels 19 are flush with the rear-facing surfaces of the privacy screen 5 or the cable duct 6. In Fig. 6, the panel 19 is also extended vertically upwards beyond the surface of the worktop 1.

and thus forms a rear support edge 21 for objects and equipment placed on the worktop 1.

To ensure stable fastening of the panel 19, the rear ends 22 of the struts 10 are bent vertically downwards and lie flat against the panels 19. A secure connection between the two parts is ensured, for example, by screwing or gluing.

In Figs. 7 and 8, the office work table according to the invention is shown in a second alternative embodiment. This corresponds to the embodiment according to Figs. 1 to 6 in the structure of the table frame made up of the two side panels 2, the base frame 3, the substructure 4, the privacy screen 5 and the cable duct 6. In addition, the worktop 1 with its rear edge 7 and the strip 9 form the cable feed-through slot 8.

In contrast to Figs. 1 to 6, in the embodiment according to Figs. 7 and 8, both the worktop 1 and the strip 9 with their side edges 26 and end faces 27 running at right angles to the slot direction 25 are slidably mounted together in horizontal guide rails 28. The guide rails 28 run along the upper edge 29 of the side cheeks 2 over the entire depth of the table. They are designed as L-angle ^profiles , on whose L-horizontal leg struts 30 projecting inwards from the side cheeks 2 the worktop 1 and the strip 9 rests.

In Fig.8A the table top 1 and strip 9 are in

it is

1 can be fixed by means of knurled screws 15' which can be screwed into threaded sleeves 16' in the worktop 1 from below at right angles to the surface of the worktop. To do this, the knurled screws 15' pass through elongated holes 31 in the L-horizontal leg struts 30 of the guide rails 28. One such pair of knurled screws and elongated holes 15'/31 is arranged in each of the square areas of the worktop 1.

The strip 9 is similarly fixed by means of knurled screws 15" that can be screwed into the strip 9 at right angles to the worktop level from below in threaded sleeves 16". These pass through holes 32 at the rear end of the L-horizontal leg/struts 30. The cable feedthrough slot 8 is flexibly closed by the cover lip-reinforcement lip-connecting strip assembly 11, 17, 15 in the position shown in Fig. 8A, analogous to the embodiment shown in Figs. 1 to 6. Cables stored in the cable duct 6 can be led through the cable feedthrough slot 8 at any point with elastic deformation of the lips 11, 17 upwards to the work area of the table. If this is not possible due to a connector plug that is too bulky in the position shown in Fig. 8A, there are two options shown in Fig. 8B and 8G to widen the cable feedthrough slot 8.

One possibility is to move the worktop 1 forwards (Fig. 8B). To do this, simply loosen the four knurled screws 15 ^e in the corner areas of the worktop 1. The worktop can then be moved forwards within the free length of the elongated holes 31. The cable with the bulky plug can be fed through the wide cable feedthrough slot 8.

"J C t t · · · I t

then the worktop 1 only needs to be pushed back into its position shown in Fig. 5A and the knurled screws 15' tightened again. The worktop 1 is then moved if the office worktable is against a wall or back to back with a second office worktable and therefore the bar 9 cannot be moved backwards.

If this is possible because the table is set up freely, the option shown in Fig. 8C for widening the cable feed-through slot 8 can be used. The two knurled screws 15" in the front area of the strip 9 only need to be unscrewed from the threaded sleeve 16" in the strip 9, whereupon the strip can be pulled backwards (Fig. 8C). The strip 9 is given additional sliding guidance by the several guide bolts 33 distributed over its length, running horizontally and at right angles to the direction of the slot, which engage with their free ends in the guide holes 34 in the rear edge 7 of the worktop 1. If necessary, the strip 9 can be completely separated from the table. If the bar 9 is to return to the position shown in Fig. 8A, it is sufficient to insert the guide bolts 33 into the guide holes 34, push the bar 9 in until the threaded sleeve 16" is aligned with the hole 32 and screw in the knurled screw 15".
