Abstract

Described is an office-desk kit with desktops of various shapes and sizes, desktop-support frames (6, 12) with top bars (8, 13, 14) designed to support the edges of the desktops and two longitudinal struts (10, 16, 17) per desktop to connect the two top bars to each other, the longitudinal struts being disposed a certain distance from the front and back edges of the desktop. The kit also includes feet (22, 30), the top bars and the feet having vertical bores in them into which vertical pillars can be inserted to form legs (20, 26, 28) of various shapes. The kit enables a large number of different desk designs to be produced, in particular designs with fitting desktops. By fitting the pillars differently between the feet and the top bars, legs of various shapes can be produced designated by the letters n, T and C. The kit includes trapezoidal desktops (45) whose geometrical shape is the result of combining a rectangular or square surface (48) with a surface in the shape of a right-angled isosceles triangle (50).

Description

KIT FOR OFFICE WORKPLACES

The invention relates to a kit for office workplaces. The invention is intended to create an inexpensive kit which nevertheless allows a large number of different forms of workstations, that is to say forms of table tops to be joined together. The components should be easy to assemble, dismantle if necessary and be able to reassemble in a different form. The components of the kit should be accommodated in relatively small packaging units, that is, for cheap transportation. A high degree of flexibility in the planning and design of office workplaces should be made possible and thus a basis for creativity of the planner. Subsequent extensions and conversions should be carried out easily and with little time.

All of this is achieved by the invention according to claim 1. Table tops of various formats are used. Matching support frames and feet of various shapes, all of which are easy to assemble.

According to claim 3, the invention further relates to a kit for office workstations with table tops of different formats, support frames for the table tops and feet of different shapes, the invention being that since J except for rectangular table tops, which are square in the limit, are trapezoidal Table tops are provided, the shape of which, viewed geometrically, results from a rectangular or square section with a section in the form of a right-angled, isosceles triangle. Independent protection, that is to say independent of claim 1, is claimed for this part of the invention. In this way, a large number of differently shaped table tops can be formed. The section in the form of a right-angled, isosceles triangle is obtained by dividing a square along its diagonals. Developments of the invention

result from the subclaims.

According to claim 2 feet of three different shapes can be formed in a very simple manner, and in addition different depths. This means a departure from the previously used four-legged tables and tables with ironing feet.

In most cases, the triangular section is placed with its one cathete on a narrow edge of a rectangular or on an edge of a square section. The outlines of such plates therefore have right angles, angles of 45 ° and 135 °.

According to claim 8, the rear corners of the table tops can be cut off, and triangular, plate-like fillers can be provided, which preferably have rounded corners and are to be fastened to the table tops instead of the missing rear corners.

The cutting off of the corners and the replacement of the missing piece with a filler piece have different meanings: on the one hand table tops of 800 mm depth can be used, on the other hand 600 mm depth, although the triangular construction would lead to a smaller depth of the narrower table top. Then plates of 800 and 600 mm depth corresponding to the DIN standard are used. The hypothesis of the trapezoidal plate of shallower depth would be longer than 800 mm. By cutting off the pointed corner of the triangular section, the inclined edge of such a table top can be shortened to less than 800 mm, so that, including a filler, a hypotenuse length of 800 mm results.

Cutting the corner has another meaning. According to claim 10, namely, insertion openings for vertical supports of superstructures which are accessible from above can be provided at the rear ends of the frames. If no structures are required, the plug-in openings can be covered by the filler pieces mentioned. Exemplary embodiments with further features of the invention are described below in the drawings.

FIG. 1 is a perspective illustration of an office work station with a rectangular plate and a plate which, viewed geometrically, has the shape of a rectangle with an attached triangle.

Figure 2 is a shortened bottom view of a support frame for a rectangular table top.

Figure 3 is a shortened bottom view of a support frame for a table top, the short side of which is inclined.

Figure 4 is a partial section in the plane IV of the support frame of Figure 3.

FIG. 5 shows a top view of variations 5.1 to 5.11 of office workstations which are to be put together using rectangular, square and trapezoidal panels.

Figure 6 is a top view of an angled work station.

Figure 7 is a partial view in the direction of an arrow in Figure 6 of the suspension mechanism.

FIG. B shows a top view of corner areas of panels of different shapes placed with one another with filler pieces and, dashed lines, the ends of frames.

Figures 9 to 11 show a work table with a structure in front view, side view and top view.

Figure 12 is a schematic representation of the depths of the narrower and lower table tops. Figure 1 shows in perspective one of many possible office workplaces, all of which are to be put together from the kit according to the invention. This work station has a rectangular table top 2 and a trapezoidal table top 4. Under the rectangular table top there is a support frame 6 according to FIG. 2. It has a frame B at each end. Both frames are firmly connected to one another by longitudinal struts 10. The support frame has the dimensions of the table top. The table top 2 has a depth of 80 cm, the table top 4 has a depth of 60 cm, which corresponds to the DIN standard 4549. Accordingly, the frames 8 have a depth of almost 80 cm. FIG. 3 shows a support frame 12 for a trapezoidal plate with a depth of 60 cm. Accordingly, its frame 13 is almost 60 cm long. The support frame has a frame 14 set at 45 °, corresponding to an oblique edge of a trapezoidal table top.

The support frame according to Figures 2 and 3 are seen from below. FIG. 4 shows a section in the plane IV of FIG. 3. The frame 8, like the other frames, are hollow tubes, one end of which is chamfered, in such a way that the frame becomes narrower at the bottom. The support frame according to FIG. 3 has a short longitudinal strut 16 and a longer longitudinal strut 17 corresponding to the inclined position of the frame 14. Since the support frame 12 is seen from below, it does not match the trapezoidal table top 4 according to FIG. 1, but instead to a mirror-image plate, but this is of no fundamental importance.

The longitudinal struts 10, 16 and 17 run a bit inwards from the front and rear edge of the table. In FIG. 1, all frames which are connected at right angles to their longitudinal struts are each provided with one foot. Figure 1 shows in principle the three possible types of feet that can be produced with the kit according to the invention. 20 denotes a C-leg, which is screwed together from the frame 8, which can hardly be seen in FIG. 1, a foot bracket 22 and two vertical supports 24. 25 denotes an n-foot, which is screwed together from a frame 14, a foot bracket 22 and two vertical supports 24. However, the two vertical supports at the C-foot 20 at one end If the frame and the foot bracket are arranged side by side, the vertical supports 24 are arranged near the two ends of the foot bracket 22 and the frame 14 at the n-foot 26. A T-foot is designated by 28, which is screwed together from a shortened foot bracket 30, a correspondingly short frame 13 and two vertical supports 24, the vertical supports here being symmetrical on both sides of the centers of the foot bracket 30 and frame 13 a ^{b are} ordered.

So that the three types of different feet described can be formed, the long foot brackets 22 have four holes 32. The foot brackets are hollow profiles at the bottom. Through the holes 32, the vertical supports 24, which are equipped with an internally threaded part, can be screwed on from below. Accordingly, the supports 24 are screwed onto the frames from above, which are also provided with holes 32 at the intervals shown. Instead, the supports 24 can be provided with a threaded pin at their upper ends in the position of use and can thus be screwed on from below.

The plates 2 and 4 according to FIG. 1 and / or their supporting frames 6 and 12 are almost but releasably connected to one another by means known per se, not shown here.

To form tables of different heights, e.g. B. 720 and 750 mm, supports of other lengths can be used.

Both the foot brackets 22 and 30 and the frames 8, 13 and 14 can be provided with further holes (not shown), which enables vertical cable ducts to be attached.

The frames 8, 13 and 14 are provided with posts 34 for attaching the vertical supports 24. The bores 34 correspond in their position to the bores 32 of the foot extensions. FIG. 4 shows that the frames have a welded-in reinforcement plate 36 at the bottom where the bores are necessary, in which there is a threaded bore 38, so that vertical supports which are equipped with threaded pins are provided from below. are steady, can turn. Instead, a head screw can also be inserted through the threaded bore 38 from above through a suitably arranged bore 40. Then supports can be used without a threaded pin.

FIG. 5 shows variants of workplaces that can be produced using a few plates. Rectangular table tops 42 and 43 with a depth of 80 cm and different lengths are used, furthermore trapezoidal tops 45 and 46, the shape of which results geometrically from the joining together of a square 48 (variant 5.1) with an isosceles right-angled triangle 50, wherein the triangle with its one cathete is placed on square 45. The length of the hypotenuse 52 (variant 5.10) gives the cantan length of a square table top 54 or a rectangular table top 56 in variants 5.6 and 5.4.

Trapezoidal platan 5B of shallower depth are also formed. These table tops can be found in versions 5.3, 5.5, 5.7, 5.9 and 5.11.

Figure 6 shows a right-angled workplace, which is composed of two trapezoidal plates of type 45 and 46 according to variant 5.4. Here, however, an intermediate plate 65 is suspended, which is formed from a rectangle and a right-angled isosceles triangle in such a way that the hypotenuse of the triangle borders on one narrow side of the rectangle. The intermediate plate 65 does not have its own frames, but rather is suspended in the frames 14 of the adjacent tables, specifically by means of holding tabs 67 according to FIG. 7. One of the holding tabs is viewed in the direction of an arrow 66 in FIG. 6. It is screwed to the frame 14 below and screwed to the intermediate plate 65 from below with a rotary knob 69.

The two corners on the side of the table tops 45 and 55 facing away from the user are cut obliquely, as can be seen in FIG. In principle, triangular but rounded filler pieces 70 can be attached to the cut corners of the table tops in order to close the plate there to complete. FIG. 6 shows that the missing corners make insertion openings 72 of the frames 14 freely accessible. These insertion openings are provided in addition to the openings described above in the frames and are used for inserting vertical supports 74 for an upper frame (third level), which is shown here in a very simple form as a board 76, on which e.g. B. a shell 78 can be attached.

Figure 8 (and 12) for a Ti3Chplatteπanordnung, which differs from that of Figure 6, more clearly show the cut ends 80 of a triangular section of a table top and 82 of a rectangular table top and the associated fillers 84 and 70, respectively, which are not shown here represented means have been put on the table tops. The frames 14 and 8 with their insertion openings 72 can be seen in FIG. 8 below the filler pieces 84 and 70.

The cut ends have another meaning in the case of triangular plate sections: if one assumes a plate diameter of 800 mm of the table plate 43 in FIG. 12, which is prescribed according to the DIN standard 4549, and the triangular construction, then the narrower one would be Table top 58 result in a depth of around 566 mm, namely B00 mm * sine 45 ° = 800 x 0.707 = around 566 mm. However, since a depth of 600 mm is prescribed for the narrower table tops according to the DIN standard, these narrower table tops are given a depth of 600 mm, whereby by cutting their tip 86, no piece of the table top can be maintained. This tip is therefore not present and replaced by a rounded filler 84. This trick makes it possible to join plates with depths of 800 and 600 mm over right-angled, identical 'Mige Draieckabschnitta.
