Office Workplace

The invention relates to office workplaces according to the preambles of claims 1, 4 and 6. These types of office workplaces are known from EP-A2-123 972.

By means of the invention, the office workplace must be formed in such a way that the additional work plates, which can be placed on the side of the table top, extend not only laterally but also forward so that the user can easily reach them. 10 The sub-rack must also be expandable in a very simple and time-saving manner, in which case care must be taken to ensure that the cables can be passed through the individual components in a very simple manner so that the cable control can be changed quickly when the structure is changed.

If necessary, the lower rack must be attached directly to the upper rack, which can support accessories such as storage shelves and the like.

It must be possible to connect the electrically-powered devices on the table top to the power supply so that the table top has only a short piece of cord and the cord does not hang down over the edge of the table top.

Concepts such as "front", "rear", "above", "below" always refer to the workplace from the point of view of the user sitting in front of the tabletop at the workstation.

The above tasks are solved in the office workplaces according to the invention, which are characterized by what is set forth in the characterizing parts of claims 1, 4 and 6.

The beveled edge, which is at least 30 cm long, usually about 45 cm, works to place the additional plates so that the entire worktop is at the same height, with the * additional plate extending to the side and forward.

Hollow fittings with large through holes and associated supports and pipe beams make it easier to change and build a workplace as well as run wires.

Further embodiments of the invention are set out in claims 2, 3, 5 and 7 to 15.

The chamfered edge may extend at an angle of about 135 ° to the front edge of the table top, giving the user a position favorable to the additional plate.

10 Corresponding to the beveled edge, a tubular beam may be positioned so that its free end is rectangularly below the beveled edge and may act to support the extensions.

In particular, in the lower frame, the pipe beams 15 form a rear connection and lateral connections between the supports, while the cable ducts pass through the pipe beams and connecting pieces and next to the supports, but between these and the associated cover plates.

In order to make it easy for the user to access the dirt channels of the cabinet, the vertical wall of the tubular beam can be formed as a hatch that can be pivoted about a horizontal axis, whereby the vertical wall preferably forms a hatch almost the entire height. In this case, the hatch can be turned with a two-part hinge, of which one hinge part is formed in one piece with the hatch, the other in one piece with the main part of the pipe beam.

Each lattice piece may have a substantially square cross-section when viewed horizontally, while the frame-like connecting plates act to secure the connecting pieces 30 to the ends of the pipe beam and the cover plates close the free sides of the connecting pieces. The connecting pieces may have angled surfaces bent at 45 ° to their side walls, which act to fasten the plates, namely to connect the connecting plates to the pipe beams and cover strips. In this case, tie-down rails can be set to adjust the height of the cover plates so that the two corner-mounted cover plates or connecting plates close the corner surfaces.

According to another embodiment, the connecting pieces can be connected from individual parts, namely the base plate, the cover plate and the side walls to be connected between them, namely closed side walls and / or open side walls for passing the wires.

Above the connecting pieces, height-10 adjustment devices can be placed, some of which fit into the opening in the table top. In addition, the height adjustment devices can provide the possibility to insert the upper rack through the opening in the table top and secure it, whereby the top rack maintains its height position unchanged despite the height adjustment of the table top.

The support arms of the upper rack can be vertical and straight or they can be in the shape of a quarter-circle, namely passing upwards and backwards from the openings in the table top. Numerous attachments can be placed in the top rack 20.

Exemplary embodiments with further features of the invention are described below with reference to the drawings.

Office workstation with accessories 5 Figure 1 shows an office workstation with a table top 2, a lower cabinet 4, a lower rack 6 with legs 7 and an upper rack 10 with support arms 12 bent backwards. Between the upper ends of the two support arms 12 there is a support 13 in the form of two parallel tubes 14 10 which can support the wall 16 acting as a visor.

As shown in detail in Fig. 2, the connecting pieces 18 form the connections between the simple supports 8 in the form of rectangular tubes forming the supporting parts of the legs 7 (or U-shaped supports 20), in the form of straight tube beams 22 and a rectangular tube beam 24. The lower ends of the legs 7 are connected to each other by pipes 21. The outermost left connecting piece in Fig. 2 is associated with a short pipe beam 23, which can be connected to the wall 20 by means of a contact plate 26.

The connecting pieces 18 have a substantially square horizontal cross-section so that pipe beams 22, 23, 24 having the same cross-section can be connected to all. from all sides. The connecting pieces have a relatively large opening at the top, which serves to pass the wires and receive a height adjustment device for the table top 2. The table top 2 has cylindrical openings 28 (Fig. 1), the position of which corresponds to the openings of each of the rearmost connecting pieces 18 in Fig. 2. Through these openings 28 the wires 30 can be routed to devices on the table top (e.g. telephone, calculator). If there are no support arms 12, V-; closing the openings 28 with a cover plate 27 (Fig. 19) having a lead-through opening 27 '. Each cover plate can be rotatably attached to a flexible ring piece 29 (ku-35 vio 20), the outer edge of which bounces over the plate. The ring housing 88886 has a notch 29 'which closes the lead-through opening at the corresponding rotating position from below, unless any lead is passed through. The ring piece 29 is mounted inside the opening 28 above the height adjustment device 5 to be described (Fig. 11).

The support arms 12 are U-shaped in cross section (Figures 1 and 21) and are closed by cable covers 38 as cable ducts. Once the support arms 12 are installed, the wires can be routed through the openings 28 to the support arms 10 and also to the table top.

The lower ends of the support arms 12 are connected to the connecting pieces 18 by means of tie rails, not shown in Fig. 2, via height adjustment devices, and thus fasten to the lower bracket. Irrespective of the changes in the height position of the table top 2, the support arms and the parts supported by them retain their height position. The support arms have cover plates 30 at their lower ends to close the openings 28 in the table top.

The horizontal cable ducts consist of the interiors of the pipe beams 22, 23 and 24 and extend through the connecting pieces 20 18. The supports 8 of the legs 7 have a rectangular, flat cross-section (cf. Fig. 11). The vertical cable ducts are formed so that the two trough-like cover plates 32 are snapped at their edges over the horizontal narrower sides of the supports 8 so that two empty spaces are formed between the supports and the cover plates 25 to receive the cable.

The U-shaped support 20 is closed by two cover plates 34 (of which only the right side is shown) having a flat top surface and bent edge portions 36. The outer edge of the rear edge portion is hinged to the narrow rear side of the support 20, the outer edge of the front edge portion is snapped to the narrow front side of the support. This creates a cable cabinet that can act to receive multi-pin sockets, transformers, and a large amount of cable (extra too long cable).

7 88356

The connecting pieces 18 not only act as a connection between the pipe beams and the supports, but can also act as a holder for the upward leg 42 for the storage shelf 45 (Fig. 1). This foot may be formed in the same way as feet 17, but it is lower than them.

The table top 2 has a chamfered edge 44 on the front left. This chamfered edge extends at an angle of 135 ° to the front edge 24 of the table top. The pipe beam 24 is at an angle of 135 °, respectively. Thus, in Figure 1, its free end is at right angles to the beveled edge 44. Instead, the chamfered edge may be on the right side of the table top, which is then shorter than shown in Fig. 1. The beveled edge is usually about 45 cm long.

Figures 3 and 4 show further forming possibilities when using a table top with a left chamfered edge 44 and a rectangular tubular beam 24. According to Figure 3, there are two legs 7 on the left connected by a short straight tubular beam 22. The left front end of the tubular beam 24, two connecting caps -20 letta 18 and tubular beam 22 function to substantially support the additional circular plate 50. According to Fig. 4, a single leg 7 is provided at the very outer edge, so that one of the connecting pieces 18 is arranged to be freely load-bearing between the pipe beams.

As shown in Fig. 5, a substantially rectangular table top can be obtained by attaching a triangular extension plate 59 to the chamfered edge 44.

Figure 6 shows additional possibilities. Attached to the oblique edge 44 is a substantially square additional plate 30 60. In the rear space, an additional plate 62 is connected between the rear edge of the additional plate 60 and the left side edge of the table plate 2. The user-facing edges likewise form an angle of 135®, while the rear edges are rounded. Below this additional plate 62 there is a lower cabinet 64, above it 35 an upper cabinet 66.

β 88356

As shown in Fig. 7, a height adjustment device 68 is mounted between the rear connecting piece 18 and the table plate 2. The lower end of the support arm 12 passes through the table plate to the height adjustment device. Behind the front edge 70 of the table top 5 are simple height adjustment elements 72.

Fig. 8 is a perspective view of a table top 2 provided with an additional square plate 60 and a top bracket 47. In each opening 28 of the table top, two vertical support arms 48 are placed, which have a U-shaped cross-section and act as cable ducts. The open sides (U-shaped cross-sections) of the support arms face each other and are closed by a cover plate 49.

Mounted between the upper ends of each support arm 48 is a support 13 in the form of a tubular beam 52, shown in cross-section in Figure 15 and Figure 9 in perspective.

The tube beam has a forward open gap 53 which acts to guide the cable. The lower part of the tubular beam acts as a cable duct 54. The tubular beam is extruded from aluminum or aluminum alloy. It has a top and bottom wall 55, 20 56 which is hollow semi-cylindrical in shape and flat, a striped rear wall 57 on the outside. The upper hollow space of the tube beam 52 is closed by a horizontal plate 73. The plate is formed in one piece by an open tube 74 at the ends. -25 to be used to secure the tubular beam 52 between the support arms 48. The ends of the tubular beam 52 are attached to the upper ends of each support arm 48. Openings in the wall 56, not shown, at the ends of the tubular beam act to pass cables from the support arms 48 to the tubular beam 52. In their U-shaped cross-section, the support arms engage each end of the tubular beam and ensure that the tubular beam cannot rotate about a horizontal axis.

The tube beam 52 serves to support a plurality of different attachments, of which only two storage shelves 75, 76 shaped in different ways 88356 are shown here. As shown in Figure 9, a support 77 is attached below the storage shelf 76 (or each other accessory) with a half below. a cylindrical recess 78 and is thereby provided in the upper wall 55 of the tubular beam 52 5. This wall has a groove 79 at each of its lower edges. Figure 10a shows an enlarged view of the shape of such a groove. Its upper surface here has an exaggeratedly large 10 * angle with respect to the horizontal. At the lower inner edges of the support 77 there are shaped claws 82 10 which engage the grooves 79 and thus hold the support 77 in different positions in the pipe beam. The support 77 is pushed longitudinally into the pipe beam. Further, the clamp 80 is in the form of a bent plate, the upper part of which is flat and fixed to the rear side of the support 77 by screws, while its lower part is bent semi-cylindrically and engages with grooves 82 in grooves 81 in the tubular beam above and below its lower wall 56.

Thus, to secure an accessory, such as a storage shelf 76, the support 77 is first pushed longitudinally into the tube beam 20, with the lower jaws 82 snaping behind the grooves 79. The clamp 80 is then mounted from below so that its front bracket 82 and the corresponding rear bracket engage each of the lower grooves 81 of the tubular beam. The upper flat portion of the clamp 80 is then screwed to the rear side of the support 77 25.

Finally, the hollow cover 83 is pushed from below over the tube beam 52, the support 77 and the clamp 80, whereby it engages itself by friction and tension.

The cables, which are passed through the openings 28 30 in the table top from below, are placed inside the support arms 48 and then in the cable duct 54 of the tubular beam. They can be taken out of the desired position of the tubular beam through the gap 53.

. The first straight line of the connecting piece and the pipe beam; 35 form

Fig. 11 shows a sectional view of a part 10 88356 of the table top 2 with a right-hand cylindrical opening 28. Below this is shown the height adjustment device 68, below it a connecting piece 18 and below it the upper end of the support 8. To the left of the connecting piece is the right end 5 of the tubular beam 22 and between them a connecting plate 88. The front opening of the connecting piece 18 can be closed by a cover plate 90. Below the connecting piece there is a transverse bracket 92 with a lower leg 94 to be placed on the support 8. The transverse support are large enough to pass through cables with connectors.

The tubular beam 22 (Fig. 11) is made of light metal by injection molding and has double walls at the top, back and bottom, which guarantee strength in the lowest possible material consumption.

It forms a main cable duct 96, the inside of which is divided by a part 98 into an inner cable duct 100 for telecommunication lines. The corners of the pipe beam 22 have holes 102 which act to place the connecting plates 88. The plate is screwed 20 with self-tapping screws 104.

The connecting plate 88 (Figs. 11, 12 and 13) has a large opening 106 equal to the openings 108 on the sides of the connecting piece 18. These openings are preferably so large that not only the wires but also their boxes 25, possibly also multi-pin sockets, can be passed through. The same is true of the height and width of the pipe beam 22 and its main cable duct 96. The connecting plate 88 has connecting rails 110 projecting from their main plane 135 ° and having an alternating height so that the space between the two connecting rails is the same as the width of the connecting rail plus the clearance. As can be seen, the right side (Fig. 12) tie rails of the spacer 88 are alternately high in height compared to the left side tie rails. This is also the case for the cover plate 90 (ku-35 vio 11). Thus, when the spacer plate 88 and the cover plate 90 are screwed 11 88356, their tie rails abut each other and thus form a top-down closed tie rail basket which completely covers one of the four oblique corner surfaces 113 of the connecting piece 18 from top to bottom.

5 To place a pipe beam (e.g. 23 in Fig. 2) on the wall, a touch plate 26 (Fig. 18) with a large opening 107 in the middle is used. The contact plate has, on the right and left, a corner surface 113 'bent at 135 ° from its main plane, with low rectangular recesses 1010 in the connecting plate 88' for each connecting rail 110. To screw the tie rails, there are threaded holes 115 'which run perpendicular to the corner surfaces 113'. After screwing the pipe beam 22 or 23 with the connecting plate, the contact plates 26 entering the wall have closed corner surfaces.

The height adjustment device is shown in Fig. 11, top, and in Figs. 16 and 17. It has a lower mounting plate 130 which can be screwed onto the connecting piece 18 from above and whose upper opening 132 is thus covered. It extends at its central portion 20 to this opening, while the mounting rails 134 engage at its four corners above its central portion. The central portion has an externally threaded sleeve 136. A sleeve with suitable internal threads (internal threaded sleeve 138) is an independent component with a cylindrical outer wall and a ul-25 flange 140 located a short distance from its lower edge. The female threaded sleeve 138 has two holes 142 which run parallel to the axis and are accessible from above. They act to set both spindles of the hole socket wrench with which the female thread-30 sleeve can be rotated. The upper mounting plate 144 is screwed from below to the table top 2. It has an opening 146 in the center to which the lower portion of the female thread sleeve 138 fits and a downwardly pressed annular edge 148. The edge 148 passes through the conical portion 150 to the mounting plate 144. The outer portion 35 has a suitable conical shape.

12 88356

For mounting, an internal threaded sleeve 138 is inserted into each opening 28 (Figures 11 and 3) of the table top from below. The upper mounting plate 144 is then screwed from both locations to rotatably secure the inner threaded sleeve 138 to the opening 28. After the lower mounting plate 130 is screwed into the connector 18 a table top 2 on top of this and the additional connecting piece so that the inner threaded sleeve 138 can be screwed into the outer threaded sleeve 136. A slotted socket wrench inserted through the openings 28 in the table-top plate 10 rotates the sleeve to another, bringing the table top 2 to a suitable height. Figure 16 shows the lower limit position on the left and the upper limit position on the right.

Mounting the Top Bracket 15 Vertical straight guides 152 (Figs. 11, 16, 17) are formed inside the outer threaded sleeve 136 to which the vertical strip-like rails 154 can be inserted from above. The tie rails are inserted at the lower end of the support arms 12 and allow the support arms to be secured through openings 28 in the table top 2 20 to the connector 18. Each tie rail is provided with a mounting screw 156 which can be tightened against the inner wall of the outer threaded sleeve 136 to prevent detachment.

Second Embodiment of Pipe Beam 25 Fig. 14 shows a pipe beam extruded from aluminum or light metal with only simply formed walls. Near its four corners are small tubes 117 made integral with the walls, the free ends of which act to rotate 30 self-tapping screws to secure the tube beam. The other side of the tubular beam is open and can be closed by a light metal or plastic hatch 118 shown in dotted lines in Figure 14. The lower end of the hatch has an approximately U-shaped hinge portion 35 119. After the hatch is placed, this hinge portion 88 88356 engages one of the small tubes 117. there is an upwardly projecting strip 121 at the top and an inwardly projecting stop portion 123, the outermost bent portion of which acts as a locking portion behind the upper left small tube 117. The door can thus be completely removed and then does not prevent the cable from being inserted inside the pipe beam. The hatch is then placed with its hinge portion 119 on the lower left small tube 117, where it snaps closed because its hinge portion comprises slightly more than one semicircle 10 in cross section. It is then lifted and locked at the top. Forward movement is limited by the response of its list against the outwardly directed portion 125 of the tubular beam.

Another Preferred Embodiment 1a of the Connector Fig. 22 shows an individual assembled connector 15 indicated in its entirety by the number 160. The connector is assembled, if necessary, from a base plate 162, a cover plate 164 and four side walls, namely one to four open side walls 166 and / or one to four closed side walls 168.

The base plate 162 is attached to the upper end of the approximately U-shaped support 170 in cross section. It has a large central opening 172 through which the cables can be led from the inside of the support upwards. The four edge portions 174 of the base plate 162 are bent 45 ° upward. Each of the side walls 166, 168 has a lower through-going slot 176 (Fig. 24) extending downwards 45e, namely so that the side wall can be placed on the edge portion 174 of the base plate. The left and right edges of each side plate extend at an angle of 45 ° to their main plane (Fig. 25). Thus, the four side walls are joined together by a quick joint 30. All side walls likewise have a 45 * bent lower edge 180 at the top (Figs. 22 and 24) which is intended to go into the recess of the plate and is bounded on the side by the upwardly rising parts 182 of the side plates.

The cover plate 164 has strips 184 on its four sides which fit into recesses 35 170. Inside them there is a pressing surface 14 88356 186, a 45 ° inclination which fits on the lower wall edge 180. The cover plate has a large central opening and an extension 188 with two parallel and two cylindrical edges wall sections, which act to connect the table-5 plate to the openings 28.

The sidewalls 166 and 168 have top-down passage troughs 190 (Fig. 25) that provide space for the spindles of the screw bolts 192.

To assemble this connector, four side walls 186, 188 are placed on the base plate 102, namely, depending on where the cable is to run, open or closed side walls. The cover plate 164 is then placed so that their strips 184 engage the recesses 179 in the side walls and hold the side walls together. Finally, screw bolts 192 are inserted from the four corners of the cover-15 plate through the holes 200, in each case into two opposite troughs 190 in the side walls, and screwed into the screw holes 202 of the base plate.

The open sidewalls 166 are secured to the tubular beam 116 by self-tapping screws 20 prior to assembling the connector.

Also in this second embodiment of the connecting piece, a height adjustment device can be placed, which operates between the extension 188 and the table top, but which is not described in detail here.
