Description

Work furniture with cable duct

The present invention relates to a work furniture with a cable channel, which has a cable channel cover plate, wherein the Kabelkanalabdeckplatte is at the same height as a worktop of the work furniture and from a covering position partially under the worktop of the work furniture is pivoted.

Various workstation systems for work furniture, especially for office space, laboratory technician and computer workstations are already known from the prior art. In order to meet different requirements in particular modular systems were developed. Examples of such systems are disclosed in DE 20 2006 008 779 U1, WO 94/16597, DE 198 48 511 A1 and DE 196 10 347 C1.

WO 02/085158 discloses a work table whose worktop consists of two telescoping rails mounted on removable plates that are mutually adjustable in height. But this leads z. B. that a raised plate can fall out of the frame of the work tables.

The work furniture or workplace systems can be compiled according to the respective requirements according to the modular principle and often with a subsequent equipment, such as a second or third "level", for example, the installation and installation of additional equipment, such as power supplies, ventilation equipment and Laboratory equipment allows. In and on workstation systems, a large number of cables are laid. These are permanently installed cables, such as the power supply to the sockets and permanently installed devices, as well as temporary lines, such as power adapters, test leads, power cables to devices that in a second or third "level or device level" The often confusing number of these lines leads in the practical application of workstation systems to obstructions in the optimal use of the workplace.

• Visual obstruction due to hanging test leads

• Excessive occupancy of workspace and thus usage restriction

• Difficult removal of successively installed prefabricated cables

• Cable overhangs lying around

• Knot of cables

Basically, these disadvantages of today's systems exist at all electrified workstations, but the problems increase with increasing number of lines and in particular with the number of temporarily laid lines to the "device levels" above the actual worktop.

Object of the present invention is therefore to provide a work furniture with a cable channel, which does not have the aforementioned disadvantages of the prior art and in particular avoids excessive occupancy of the work surface, so that the work furniture for the user easier to handle and more effective. This object is achieved by a work furniture with a cable channel, which has a cable duct cover plate, wherein the Kabelkanalabdeckplatte is at the same height as a fixed ie not movably arranged worktop of the work furniture and from a covering partially under or perpendicular to the worktop of the work furniture is pivoted. Typically, the work furniture has one or more wired or to be wired device levels above the actual worktop.

In the hitherto conventional solution of the prior art with a hinged Kabelkanalabdeckplatte it is necessary to provide the inlet slot on the table facing side of the flap. Otherwise, the lifted lines would have to be lifted when lifting the flap. In addition, the flap would obstruct the view of the cable channel in the open state.

These disadvantages are avoided since the pivotally arranged Kabelkanalabdeckplatte is at least partially retractable under the worktop of the work furniture or preferably perpendicular to the worktop of the work furniture is pivotable. In the open state, the view of the cable channel is thus released and facilitates the replacement and the addition of additional cable lines, since the cables no longer need to be raised.

"Pivotable" in the sense of the present invention means that the rear plate can only be moved relative to the fixed (fixed) front plate in contrast to the teaching of WO 02/085158, where two against each other freely movable and unfixed plates can be moved freely against each other The system according to this teaching is more accident-prone and less accurate and easy to handle than in the present invention.

Preferably, the cable duct cover plate is completely pivotable under the worktop of the work furniture and is completely submerged under the actual countertop, so that the access to the cable channel is particularly simple.

In particularly preferred embodiments of the invention, the cable channel cable routing elements, such as knobs, a so-called cable register, as described for example in unpublished DE 10 2006 049 048, and other geometrically largely arbitrarily selectable separating elements to separate the laid cables from each other.

The separating element can have a two- or three-dimensional shape, so that a separating element is also to be understood as meaning a U-shaped or a hollow profile with cable feedthrough openings provided therein. The longitudinal direction of the channel indicates the direction in which the cables are laid in the channel and is usually the direction with the greatest length extension of the channel. The channel is preferably a U-shaped profile, although other profile shapes, such as V-shaped profiles or semicircular profiles are suitable. As already mentioned above, the channel is at least partially open towards an opening side extending in the longitudinal direction of the channel, so that an access possibility to the cables is formed on the opening side. For example, a U-shaped profile on the non-closed side forms an opening side which is preferred in the context of this embodiment. However, the opening side can also have openings or plates limited by webs. By arranged on the opening side of the channel webs or plates, the stability of the channel is increased. General offers the open side the advantage of a simplified access to the cable channel to facilitate routing of cables.

The cable duct cover plate preferably has a pivoting hinge, which represents a particularly simple and cost-effective solution for the purposes of the present invention. Particularly preferably, the pivoting hinge on a locking device, so that the partially or entirely submerged under the actual worktop cable duct cover plate can be determined without the risk of folding back. In further preferred embodiments, the function of the pivoting hinge is taken over by a linkage arrangement described below.

The cable duct cover plate has a sealing cable bushing, so that the cables laid in the cable channel can be routed to the devices, which are usually located on a device level or even the actual worktop, with cable connection.

According to the cable duct is attached to the opposite side of the worktop the Kabelkanaldeckplatte, whereby advantageously the available area of the actual worktop is considerably increased, so that, for example, even more equipment on the worktop space. It also avoids that the cables leading to the equipment at the device level hang too far into the work surface, but are attached to the periphery of the workstation.

Typically, the cable gland on a sealing cable outlet, which is designed in the form of a brush strip, a soft rubber or foam element, etc. This sealing cable outlet is at the actual Working surface facing away from the longitudinal side of the cable channel and / or the cable channel cover plate attached.

An exemplary embodiment of the present invention will be explained in more detail below with reference to the accompanying drawings. Showing:

Fig. 1 is a perspective view of a work piece of furniture according to the invention;

Figure 2 is a fragmentary cross-section through the Kabelabdeckplatte and the actual work surface.

Fig. 3 shows another embodiment of a pivotable Kabelabdeckplatte in a partial cross section.

Figure 1 shows an inventive work furniture 100 without additional equipment levels, which may of course also be present in other embodiments. The work furniture 100 has a table top 101 (also called "actual worktop" or "work surface") and schematically illustrated support legs 102. The support legs 102 are either solid or can also consist of a hollow profile in which, for example, cables can be laid. Generic hollow sections are described for example in DE 31 33 456. At the back of the table top 101, a cable channel 105, 107 is attached. The cable duct 105, 107 is covered by a cable duct cover plate 104 which can be pivoted under the table top 101 by means of the pivoting hinges 103. On the rear longitudinal side of the table top 101 opposite longitudinal side of the Kabelabdeckplatte 104 is a sealing cable guide 106 is attached, which is formed for example of soft rubber, foam, etc, or in the form of a so-called brush strip. FIG. 2 shows the mode of operation of the pivotable cable channel cover plate of the work piece 200 according to the invention in a sectional cross-sectional view.

In Figure 2a, the Kabelkanalabdeckplatte 202 is closed and is consistent at the same height on the table top 201 at. The pivot hinges are not shown in Figure 2a. In the cable channel 203, a cable 210 is shown by way of example, that leads through the sealing cable guide 204 to a device, not shown either on the table top 201 or on a device level, not shown. As in FIG. 1, the sealing cable guide consists, for example, of soft rubber, foam, etc., or is present as a so-called brush strip. When pressure on the Kabelkanalabdeckplatte 202, represented by the arrow F, pivots in Figure 2b, the Kabelkanalabdeckplatte 202 at the pivot hinges 205 in the direction of arrow obliquely downward. FIG. 2c shows the locked rest position of the cable duct cover plate 202, which has been lowered almost completely underneath the table top 201. By simply pulling on the Kabelkanalabdeckplatte 202, or on a handle, not shown, the Kabelkanalabdeckplatte 202 pivots back to its original position, which is shown in Figure 2a.

In Figure 3, the operation of another embodiment of the pivotable Kabelabdeckplatte is shown.

Instead of the pivoting hinge shown in Figure 2, a so-called linkage arrangement is used in Figure 3.

In Figure 3a, the Kabelkanalabdeckplatte 302 is closed and is consistent at the same height on the table top 301 at. The cable channel 303 has no sealing cable guide. The sealing cable guide 304 is only at the Kabelkanalab- cover plate 302 attached. Of course, in other embodiments, the sealing cable guide may be attached to both the cable channel cover plate 302 and the cable channel 303 as in FIG. As in FIG. 1, the sealing cable guide consists, for example, of soft rubber, foam, etc., or is present as a so-called brush strip. The linkage arrangement consists essentially of two link strips 311, 312 with a not shown in detail lateral channel-like recess as a guide, in each of which one attached to the Kabelkanalabdeckplatte 302 roller 310 is guided. Instead of the roller 310 may also be a pin or other means are used, which performs the same function.

When pressure is exerted on the rear part of the cable duct cover plate 302, represented by the arrow F, in FIG. 3b the cable duct cover plate 302 pivots obliquely downwards on the rollers 310 in the guide strips 311, 312, as shown in FIG. 3c. In Figure 3d, the locked rest position of Kabelkanalabdeckplatte 302 is shown, which has now been lowered perpendicular to the table top 301. By simply pulling on the Kabelkanalabdeckplatte 302, or on a handle, not shown, the Kabelkanalabdeckplatte 302 pivots back to its original position, which is shown in Figure 3a.
