Description

The invention relates to a work table with a receiving compartment, which is designed to accommodate technical equipment. The technical devices are in particular data processing and communication devices that are integrated in the work table.

Modern workplaces have a variety of technical devices such as personal computers (PCs), printers, dictaphones, telephones and faxes. This often means that the worktop of a work table is converted as a device storage space and barely usable for office work. In particular, personal computers take up a considerable amount of space.

From the publication DE 195 33 494 C2 is a work unit known that allows easy integration of all devices of a modern office workstation in the work unit. For this purpose, the working unit has a hinged top plate and one or more containers, which on the side facing the top plate are open and allow the accommodation of a variety of technical devices or parts thereof. The top plate serves as a lid for the container or containers.

In the US2008 / 0224582 A1 a work table is described with a receiving compartment, which is designed to accommodate cables. There are upper and lower plates which are arranged in parallel and displaceable relative to one another. In this case, a gap is provided between a rear fixed area and the movable area of the work table.

The present invention has for its object to provide a further work table with a receptacle for accommodating technical equipment, which allows integration of technical equipment, in particular a computer and the associated wiring in the work table.

This object is achieved by a work table with the features of claim 1. Embodiments of the invention are specified in the subclaims.

Thereafter, the work table on an upper and a lower plate, which are arranged parallel and immediately adjacent to each other and thereby displaced relative to each other. By moving the plates relative to each other, the receptacle is released or closed. Further, a rear cross member is provided, to which the upper plate in the closed position, in which the receiving compartment is closed, immediately adjacent.

The present invention provides a solution in which by horizontal displacement of two superimposed plates, a receiving compartment can be released or closed. The receptacle serves to accommodate and accommodate technical equipment such as a computer. In the open position, technical devices and the associated wiring can be inserted into the receptacle. In the closed position, the technical devices and associated cables are safely stowed in the receptacle without requiring space on the work surface of the worktable or next to or below the worktable, and providing a tidy appearance. By abutment of the top plate in the closed position directly to the cross member, a substantially complete and lockable closure of the receiving compartment in the closed position is made possible.

The fact that the upper plate directly adjoins the rear transverse element in the closed position means that the upper plate, at least in sections, directly adjoins the transverse element without a gap remaining therebetween. However, this does not exclude that local openings, such as circular or rectangular openings for taking out cables from the receiving compartment, are provided between the cross member and the upper plate. Next, the qualification of the cross member as a rear cross member means that this is based on the sitting position of a user of the work table at or near the back of the work table.

The fact that the upper and lower plates are arranged "immediately adjacent" is to be understood as meaning that no further components of the work table are interposed therebetween, but rather that the upper and lower plates directly follow one another in their parallel arrangement. On the other hand, the arrangement "immediately adjacent to one another" does not mean that the plates necessarily touch flatly. It may well be provided a small distance between the plates, in particular of up to about 1 mm, for example, by guide elements such. Longitudinal grooves of a plate and engaging therein longitudinal guides of the other plate is caused.

In one embodiment of the invention, the top plate is the worktop of the worktable. At least one recess is provided in the bottom plate to provide access to the receptacle located below the bottom plate. By advancing the upper plate relative to the lower plate, the recess in the lower plate is accessible or closed and thus released or closed access to the receiving compartment.

The receiving compartment is formed for example by a channel which extends from a narrow side of the work table to the other narrow side of the work table.
The receptacle is open on its side facing the lower plate and secured to the work table such that there is access to the receptacle through the recess. The cross section is for example rectangular.

The height of the receiving compartment is for example such that a small computer such as a slimline PC or a mini-PC in the receptacle can be stowed. However, the height of the recording compartment is variable and larger PCs can be accommodated therein. It may be lined with an electromagnetic radiation shielding material and / or a sound absorbing material. The receptacle may further comprise a plurality of openings, for example, allow the implementation of lines for power supply, for connection to peripheral devices and telecommunications.

As already explained, a rear cross member is provided, which are also referred to as a cross-wood or cross bar and can be made of any material. It can be provided that the transverse element is arranged on the end face of the work table facing away from a user of the work table, extends between the narrow sides of the work table and has a longitudinal edge facing a user of the work table, to which the longitudinal side of the upper plate facing away from a user of the work table immediately adjacent in the closed position. The cross member is, for example, plate-shaped, arranged on the lower plate and fixedly connected thereto, and has the same thickness as the upper plate. It can also be provided that the lower plate ends in front of the transverse element. For this case, the cross member preferably has a thickness which corresponds to the sum of the thicknesses of the lower plate and the upper plate.

About the cross member a frontal stop for the top plate is provided.

In a further embodiment, the work table has a locking device, by means of which a relative movement between the upper plate and the lower plate in the closed position can be blocked. As a result, computer hardware or other technical devices contained in the receptacle can be protected from access by unauthorized persons.

Furthermore, the worktable preferably has means, for example in the form of a stop or a detent device, which allow a relative movement of the upper plate relative to the lower plate only over a defined path. This prevents the top plate from being completely removed from the bottom plate.

In order to provide a defined relative movement between the upper plate and the lower plate, in one embodiment of the invention, a linear guide is provided which exclusively controls a movement of the upper plate relative to the bottom plate in the plane of the respective plates allowed. The linear guide is designed in a variant as a dovetail guide. In another embodiment variant, the linear guide comprises a bar connected to the upper plate, which surrounds the edge of the lower plate and thereby provides a positive connection between the upper plate and the lower plate.

In addition, at least one longitudinal groove may be formed in one plate, into which engages at least one correspondingly shaped projection of the other plate. Preferably, at least three parallel longitudinal grooves are provided in the one plate, for example, a height of 5mm to 10mm, wherein in the other plate in each case an elongated guide, for example a plastic guide, is provided, which engages in the longitudinal groove. This reduces or eliminates the risk of tilting of the two plates during a displacement movement. About the longitudinal grooves and the elongate guides can be made in a variant, a minimum distance between the two plates of up to 1 mm, in particular of 0.5 mm.

In a wide embodiment of the present invention, at least one monitor compartment is provided in addition to the receptacle, which serves to accommodate at least one retractable monitor. The monitor compartment is located behind the receiving compartment from the perspective of the user of the work table and is adjacent to the rear end side of the work table.

In this case, it is provided in one embodiment that the monitor compartment is designed in such a way in the work table, that even with the receiving compartment open no access from above to the monitor compartment is given. The monitor compartment and the receiving compartment are thus preferably completely separate, so that there is no access to the receiving compartment and, in particular, computers or other electrical and electronic components arranged in the receiving compartment via the monitor compartment.

For this purpose, it is provided in one embodiment that the monitor compartment is formed below the rear cross member. In this case, at least one flap is formed in the transverse element, which opens at a vertical extension of the monitor from the monitor compartment and which closes when retracting the monitor in the monitor compartment again. The flap is self-opening and self-closing, ie an opening and closing takes place solely due to the movement of the monitor.

Furthermore, it can be provided that the monitor compartment has a greater height and / or a smaller depth than the receiving compartment. It can also be provided that it is designed to be open at the bottom. This has the advantage that things such. As pens that fall into the monitor compartment, can be repealed in a simple manner from the ground again.

The FIG. 1 shows a work table 1, which comprises a top plate 2 and a base plate 3. The base plate 3 is also referred to below as the lower plate. The top plate 2 and the base plate 3 are arranged parallel to each other and lie directly on each other. They are about one in the FIGS. 8 and 9 exemplary shown linear guide in its plane of extent, ie in the horizontal direction, relative to each other movable. In this case, the upper plate 2 via the linear guide relative to the base plate 3 is displaceable, in the illustrated embodiment such that the upper plate 2, starting from a in the Figures 5 and 6 illustrated closed position in a in the FIGS. 1 and 4 shown opened position is displaceable.

The top plate 2 represents the worktop of the work table 1. It is designed for example as a laminate-coated furniture board. The base plate 3 preferably also consists of a wood material, such as a plywood board, a laminate board or a chipboard. All components of the work table 1 are made in one embodiment of wood.

The work table 1 is formed according to the usual shape of a desk in a rectangular shape. He thus has two narrow sides 101, 102, an end face 103 and a rear side 104. Adjacent to the end face 103, and thus adjacent to a user of the work table facing away from the long side of the work table, the base plate 3 has two recesses 71, 72. Between the recesses 71, 72, the base plate webs 31, 32, 33 forms. It should be noted that the presence of two recesses 71, 72 is to be understood merely as an example. It can also be provided a different number of recesses, optionally in another form and elsewhere in the base plate. 3

The base plate 3 is connected to the two narrow sides 101, 102 of the work table 1 in each case with at least one stand element 5. In the illustrated embodiment, a stand element is formed in each case by a rectangular plate 5. Alternatively, however, table legs may be provided as stand elements.

The work table 1 further has a receiving compartment 6. This is rectangular in cross section, wherein the base plate 3 facing upper side is open. The receiving compartment 6 extends from a narrow side 101 to the other narrow side 102 of the work table and is secured to the base plate 3 and / or the stand elements 5, that through the recesses 71, 72 in the base plate 3 from above access to the receiving compartment. 6 given is.

At the end facing away from the user 103 of the work table 1, a cross-wood 4 is further provided, which is fixedly connected to the base plate 3. The crossbar 4, which may also be referred to as a transverse element or cross bar, has a longitudinal edge facing a user 40, which in the closed state of the work table, as in the Figures 5 and 6 is shown directly adjacent to a front longitudinal edge 20 of the top plate 2. The cross-wood 4 is formed as well as the top plate 2 and the base plate 3 plate-shaped and has the same thickness as the top plate 2 in one embodiment. The width is the same as the width of the worktable.

The transverse wood 4 represents via its longitudinal edge 40 a stop for the movement of the top plate 2. In addition or alternatively, a limitation of the movement of the top plate 2 by longitudinal grooves (see. Figures 10 and 14 ) are provided, which are formed in the lower plate 3 and engage in the projections or longitudinal guides of the upper plate 2. The longitudinal grooves are dimensioned so that the movement of the top plate 2 is stopped just when the longitudinal edge 20 of the top plate 2 comes against the longitudinal edge 40 of the cross-wood 4.

When the longitudinal edge 20 of the top plate 2 comes against the longitudinal edge 40 of the cross-wood 4, the work table 1 is closed. About an optional locking device, not shown, which includes, for example, a lock cylinder can be locked in the closed position of the work table 1, so that the top plate 2 is no longer movable relative to the base plate 3.

In the illustrated figures, the cross-wood 4 is arranged as arranged on the base plate 3 and firmly connected cross bar. Alternatively, it may also be provided that the base plate ends in front of the transverse wood and this is connected to the base plate and / or the side elements. In this case, the transverse wood is thicker and has a thickness which is at least equal to the sum of the thicknesses of the upper plate 2 and the base plate 3. The cross-wood 4 can basically be designed in any desired way, as long as it provides a rear stop for the top plate 2.

The receptacle 6 serves to accommodate technical devices, in particular a computer and an associated wiring and power supply. This is exemplary in the FIG. 7 shown. Thereafter, located in the receptacle 6, a cable channel 61 which extends longitudinally between the narrow sides of the work table 1. The cable channel 61 is also rectangular in section and adjoins the one side wall of the rectangular receiving compartment 6. In the receptacle 6 Furthermore, a computer 10 and a socket 610 are arranged. A plurality of cables 611, which are guided in the cable channel 61, serves the power supply and communication connection of the computer 10. The computer 10 is for example a so-called slimline PC or mini-PC, which is characterized by a small size.

About the socket 610 more technical equipment in the receiving compartment 6 can be arranged.

The dimensions of the receiving compartment 6 are, for example, 0.3 m × 0.3 m × 1.5 m (height × width × length). Depending on the space required but the dimensions may be different. For example, the height can vary between 0.1 m and 0.5 m, the width between 0.1 m and 0.5 m and the length between 0.8 m and 2.5 m.

The receptacle 6 and the stand elements 5 of the worktable 1 have a plurality of openings which allow the passage of electrical cables, and thereby, for example, the lead out of cables from the receptacle 6 for connecting a screen, for connection to an outlet formed in an adjacent wall or for communication technology connection to adjacent, appropriately designed work desks. For this purpose, the stand elements 5 on recesses 51 which are formed in the region of the end faces of the receiving compartment 6 in the stand elements 5, so that cables can be led out in the longitudinal direction of the receiving compartment 6 from the working unit 1 or brought into this. Furthermore, the receiving compartment 6, as in the FIG. 2 can be seen on at least one wall, in particular on the bottom wall or on one of the side walls, recesses 61, via which, for example, a power cable can be supplied.

Further recesses 9 (cf. Figures 5 and 6 ) are formed by recesses 21 in the top plate 2 and recesses 41 in the cross-wood 4. In the closed state, these recesses 21, 41 in the Figures 5 and 6 Openings 9 shown through these openings, for example, a cable for connecting a screen or a keyboard from the receiving compartment 6 are led out. It can be provided that a computer screen in the region of the cross-wood 4 is arranged on the work table 1, so that an opening and closing of the work table is possible without the need to change the computer screen.

The number, size and shape of the openings 9 is shown by way of example only. For example, it may alternatively be provided that substantially rectangular recesses are formed either on the longitudinal edge 20 of the top plate 2, on the longitudinal edge 40 of the transverse timber 4 or by these two together, which are then closed by one or more brush strips, through the cable in the Shelf 6 can be guided or led out of this.

Based on FIGS. 8 and 9 The type of linear guide between the top plate 2 and the base plate 3 will be explained below. According to one in the FIG. 8 illustrated first embodiment, the linear guide is designed as a dovetail guide. In the lateral edge region of the top plate 2 is below the top plate 2, a bar 22 attached with an oblique end face 221, wherein the end face 221 of the also tapered end face 35 of the base plate 3 faces and these run parallel to each other. The angle of the dovetail toothing is for example between 20 ° and 40 °, in particular about 30 °. Corresponding linear guides are formed on the two sides of the working unit 1.

By the linear guide described on the one hand, a displacement of the upper plate 2 relative to the base plate 3 is made possible. At the same time, the dovetail guide causes a form fit, which prevents vertical movement of the top plate 2 relative to the base plate 3, so that the top plate 2 can not be folded up.

The preparation of the dovetail guide is possible in a simple manner, since this only the bottom plate 3 along a line that later forms the tapered end face 35, must be sawed through at an angle. The resulting sloping part forms the bar 22 and is attached to the underside of the top plate 2.

The dimensions of the bar 22 are consistent with the dimensions of the top plate 2, so that they are flush on the side edge of the worktable 1. The thickness of the strip 22 corresponds to the thickness of the base plate 3. The strip 22 thus forms at the same time a kind of screen that covers the base plate 2 optically. Optically, the impression arises as if a single worktop with a thickness is present which is equal to the sum of the thicknesses of top plate 2 and base plate 3. These are preferably both the same thickness, so that visually the top plate 2 appears twice as thick as it actually is. The thickness of the base plate 3 and the top plate 3 is for example, in each case between 10 and 30 mm, for example, in each case 20 mm, for which case there is optically a lateral view of the working unit a 40 mm thick worktop.

To achieve the optical effect of a single worktop, the top plate 2 also on its back 104 on a screen 23, such as in the Figures 2 . 3 and 6 is shown.

In the FIG. 2 is the top plate 2 with the screen 23 and the bar 22 of the linear guide in the unassembled state, that is shown before the connection to the base plate 3. It can be seen that the bar 22 of the linear guide has a projecting portion 22 a, which projects beyond the front longitudinal edge 20 of the top plate 2. This area 22a comes in the closed position of the work table 1 below the cross-wood 4 to rest against the corresponding end face of the base plate 3. In the FIG. 3 It can also be seen that also the cross-wood 4 has a screen 42, so that the work table 1 acts from all four sides as a work table with a uniform thickness.

To connect the top plate 2 with the base plate 3, the top plate is pushed by means of the linear guide on the base plate 3. In the FIG. 3 the upper plate 2 is pushed onto the base plate 3. It will now be the one stand element 5 is mounted. The assembly of the work table is then completed.

For connecting the individual elements, in particular for connecting the base plate 3 with the stand elements 4 and for connecting the receiving compartment 6 on the one with the base plate 3 and the other with the stand elements 5 screws 8, for example, are provided which connect the corresponding parts in a conventional manner.

As in particular in the Figures 2 and 3 can be seen, the stand element 5 at its upper edge, which is connected to the base plate 3, an elongated recess 52. This recess 52 serves for the optional attachment of a connecting part, for example in the form of a connecting plate or wood element, by means of which the working unit can be connected to a further, correspondingly formed working unit.

The FIG. 9 shows an alternative embodiment of the longitudinal guide between the top plate 2 and the base plate 3. Thereafter, a bar 24 is provided, which is a below the base plate 3 extending projection 240 and thereby on the one hand provides a linear guide and on the other hand a form fit, which prevents movement of the top plate 2 at an angle or perpendicular to the base plate 3. A linear guide is present insofar as a lifting of the top plate 2 is prevented.

In both variants of the longitudinal guide, the lower plate 3 has a slightly shorter length between the two narrow sides 101, 102, since not the lower plate 3 itself, but the bar 22, 24 is flush with the upper plate 2. However, apart from the wider of the cross-wood 4, the upper plate 2 and the lower plate 3 have substantially the same dimensions.

The in the FIGS. 8 and 9 illustrated embodiments of a linear guide are only to be understood as examples. Any other types of linear guide may be provided.

The FIG. 10 shows a further embodiment of the invention, in which in the base plate 3, an additional longitudinal guide in the form of a groove 36 is formed. The groove extends in the direction of displacement of the plates 2, 3. On the underside of the top plate 2, one or more projections (not shown) are shown, which correspond to the shape of the groove 36 and project into it. By this additional longitudinal guide the risk of tilting of the top plate 2 relative to the base plate 3 is eliminated in a sliding operation.

It can be provided that, after the top plate 2 is arranged on the base plate 3, the top plate 2 is movable only over a limited distance relative to the base plate 3. Thus, on the one hand, it should be ensured that the openings 71, 72 can be exposed to access the receiving compartment 6 by moving the top plate 2. On the other hand, a complete removal of the top plate 2 is prevented by the base plate 3. This possibility could, for example, be the reason for the improper use of the work table when using the work table in schools. In order to limit the relative movement between the plates 2, 3, for example, a locking device is provided, for example in the form of a (not shown) stop or by means of a locking device which engages when the top plate 2 is a defined distance relative to the base plate 3 is moved.

In further embodiments (not shown), it may be provided that one or more pen drawers or keyboard separations are located below the base plate 3 on the rear side of the worktable facing a user. Furthermore, a USB connection can be integrated in the tabletop, which allows the connection of devices or storage media. The corresponding wiring is guided over one of the openings of the receiving compartment 6 in this. Further, a DVD and / or floppy disk drive can be integrated as an external drive to the base plate 3 and / or in a drawer.

Also, in one embodiment, a retractable monitor can be integrated into the work table. The monitor is arranged in the receiving compartment 6 and can be moved vertically upward by a suitable device from the receiving compartment 6, so that it can be used as a computer screen. For this purpose, it may be provided that a slot or the like is located in the top plate 2, through which the monitor can move out of the receptacle 6 upwards or can be sunk into the receptacle 6.

In a preferred embodiment, all parts of the work table 1 according to the invention consist of a wood material, which in particular plywood boards, laminate boards and chipboard are understood. Only the screws or the like for connecting the individual elements of the work table are made of metal. If the receptacle 6 is formed of wood, it may be provided to line this with a mat for sound insulation and / or protection against electromagnetic radiation.

The work table 1 provides a relative movement between the top plate 2 and the base plate 3 without the use of rollers, roll-outs, metallic sliders or the like. Rather, the top plate 2 and the base plate 3 are directly adjacent to each other. As explained, this does not exclude a minimum spacing of the plates 2, 3 of up to 1 mm. On the coefficient of friction of the adjoining surfaces of the top plate 2 and the base plate 3, the sliding ability of the plates 2, 3 can be adjusted to each other in embodiments in which the plates 2, 3 touch flat.

The FIGS. 11 to 16 show a further embodiment of a work table 1 ', which essentially by the additional training of a monitor compartment of the embodiment of FIGS. 1 to 10 different. The mechanism for opening of the work table using a top plate 2 and a bottom plate 3, which are arranged parallel to each other and movable in the horizontal direction relative to each other, is the same. The same reference numerals on the one hand in the embodiment of FIGS. 11 to 16 and on the other in the embodiment of FIGS. 1 to 10 denote identical or corresponding parts.

The FIG. 11 shows a work table 1 ', which has a top plate 2 which is linearly displaceable relative to a non-visible base plate. It is a screen 23 corresponding to the screen 23 of FIG. 2 recognizable. It is further provided in a rectangular cross-section receiving compartment 6, which extends from a narrow side to the other narrow side of the work table 1 'and is arranged below recesses of the non-visible base plate, so that these recesses in retracted top plate 2 access to the Shelf 6 is given. It is in this respect to the description of FIGS. 1 to 10 Referenced. The receiving compartment 6 is formed by two parallel side walls 63 65 and a bottom plate 64.

Two stand elements 5 are as in relation to the FIG. 3 explained educated.

Behind the receiving compartment 6, ie adjacent to a user of the work table 1 'rear side facing away from the work table 1', a monitor tray 9 is formed. As in particular the side representation of the FIG. 12 It is formed by two parallel, vertically extending plates 91, 92, wherein the plate 91 in its upper region also forms the one side wall 65 of the receiving compartment 6. It can be seen that the monitor compartment 9 in comparison to the receiving compartment 6 has a greater height and a smaller depth. Unlike the receiving compartment 6, the monitor compartment 9 has no bottom plate, so that objects falling into the monitor compartment 9 from above can be lifted off the ground in a simple manner.

The FIG. 11 further shows a closing element 150 of a locking device, not shown, which includes, for example, a lock cylinder. By means of the closing element 150, the top plate 2 in the illustrated closure position, when it is directly adjacent to the user of the work table 1 'facing longitudinal edge of the cross-wood 4, are closed. As a result, the receiving compartment 6 is firmly closed. This is for example when using the work table in the Everyday school life advantageous because this free access of students to the arranged in the receptacle technical devices or computers is prevented.

The two plates 91, 92, which form the monitor compartment 9, also extend from one narrow side to the other narrow side of the work table 1 '.

The monitor compartment 9 accommodates two monitors (not shown) and a hydraulic 110, 115 for moving the monitors from a retracted position, in which the monitors are located entirely within the monitor compartment 9, in an extended position, in which the monitors themselves located above the desk top 2. The associated hydraulics is particularly in the FIG. 13 to recognize. Thereafter, a hydraulic actuator 110 is provided, which is movable by means of a hydraulic drive with a cylinder which is arranged in a rectangular housing 115 in a linear direction, ie in the vertical direction. At the upper end of the actuating element 110 is a mounting plate 120, which serves to attach a monitor, not shown. As a monitor, a flat screen is typically used.

The actuator 110 is formed as a rectangular profile and is guided on the rectangular housing 115. As a result, a rotatability and thus unwanted pivoting of the monitor are prevented.

The housing 115 is fastened to the inside of the rear plate 92 via fastening means 117. Due to this fact and in addition to concealing the hydraulics 110, 115 when viewing the worktable from the back, the back plate 92 is pulled down almost to the floor.

In the rear cross bar 4 two recesses 140 are formed, which are each covered by a flap 130. The flap 130 is in each case self-opening and self-closing, d. H. it opens automatically when the corresponding monitor is moved upwards from the monitor compartment 9, and automatically closes again when the monitor is moved back into the monitor compartment 9. The flap 130 is made of sheet metal or aluminum, for example.

If the lower plate extends to the rear end of the work table and below the cross-wood 4, which is the case in one embodiment, the recess 140 naturally also extends through the lower plate.

Next forms the cross bar 4 on the narrow sides of the worktable 1 'each have a view bar 44.

The FIG. 14 shows the work table of the FIGS. 11 to 13 on the one hand with the upper plate 2 displaced forwardly, so that access to the receiving compartment 6 is afforded by the openings 71, 72 in the lower plate. On the other hand, the monitors have moved out of the monitor compartment 9.

As already in relation to the FIG. 12 has been noted, due to the fact that the monitor compartment 9 is formed below the cross member 4, no access from the openings 140 of the cross-wood 4 to the receiving compartment 6 given. A manipulation or removal of the electrical equipment arranged in the receiving compartment 6 via the openings 140 in the transverse wood 4 is thus not possible. Conversely, this means that even in the open position of the work table 1 'on the recesses 71, 72 of the lower plate no access to the monitor compartment 9.

The FIG. 15 shows the work table in the closed position. About the closure member 150, the top plate 2 is firmly locked to the transverse bar 4, wherein the respective longitudinal edges or end faces abut directly against each other. However, according to the presentation of the FIG. 1 For example, circular or rectangular openings may be provided through which cables and the like can be guided from the receiving compartment 6 to the top of the work table. Such openings are formed for example by corresponding recesses in the upper worktop 2 and / or the cross-wood 4 in the region of the mutually facing longitudinal sides of these elements.

The FIG. 16 shows the work table in the closed state, now also the monitors in the monitor compartment 9 are sunk. The flaps 130 in this state cover the openings 140 for the monitors.

For example, the worktable is designed for two student workplaces and has a dimension of 1.60 mx 0.80 mx 0.74 m (width x depth x height).

The work table described can also be designed with only one monitor and corresponding hydraulics or with more than 2 monitors and appropriate hydraulics.

The embodiment of FIGS. 11 to 16 enables a simple, fast and safe retraction and extension of the monitors. In the school sector, it may be provided, for example, that the monitors are simultaneously extended and retracted at the touch of a button by the teacher. A group control of the monitors for a plurality of workstations is also possible.

Thus, one or more computers can be integrated into the worktable 1 ", thereby being closed and protected against unauthorized access, soiling and damage.For a data transfer, a USB connection can be provided on the monitor, for example Moreover, electronic radiation as well as noise and heat pollution are minimized by arranging the computer in the receiving compartment.

A preferred application of the work table according to the invention is as mentioned in educational institutions such as schools, call centers and open-plan offices. By locking the top plate 3 with the base plate 2 can be ensured that unauthorized third parties can not gain access to the arranged in the receiving compartment hardware. At the same time, the encapsulation of the computer in the storage compartment of the worktable reduces the noise level in the room.

However, the work table according to the invention is also suitable as a single space variant for offices and private study, as avoided by the arrangement of the technical devices, in particular the PC and the associated wiring and power supply in the receptacle "cable salad" and a tidy impression is provided. In the receptacle while other cables, such. B. for telephone or desk lamp.

Despite the efficient stowage of the computer and / or other technical equipment in the receiving compartment 6 of the work table a simple and handy access to the technical equipment is possible, since this only the top plate 2 has to be moved relative to the base plate 3. On the top plate 2 existing objects need not be removed beforehand, as they can not fall over by the parallel movement of the top plate 2, unlike a pivotal movement of the top plate.

It should be noted that the switching on and off of a arranged in the receptacle 6 computer is unproblematic even when the work table is closed. Thus, the computer can be switched on and off via power management applications as they are known per se (eg automatic booting with power supply).

The invention is not limited in its embodiment to the embodiments shown above. For example, instead of rectangular plates 2, 3, the worktable may also have working tables embodied in other ways, in which the plates are rounded, for example at their corners, or are generally oval. Further, for example, be provided that instead of a extending between the narrow sides of the work table receiving compartment a plurality of separately formed receiving compartments are provided which are each associated with a receiving opening in the base plate.
