Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a desk or table having two side parts and a connecting part which is removably connected to the two sides and connects the two sides to each other.
This type of table is available in West German unexamined applications.
It is disclosed in the specification of No. 3056173. In this known table, the two sides are connected to each other by a transverse support rod and also by a table top provided between the beams on both sides. The table is joined with screws, but the screw joints are located directly below the table top, making it difficult to install. Such a threaded joint is actually necessary in order to disassemble the table and reduce the space it occupies during transportation. However, since tables are often subjected to relatively strong forces continuously, the tightening force at the joints may become insufficient, causing them to loosen or wobble, in which case the table will wobble and will need to be repaired. There is.

Therefore, one purpose of the present invention is to solve the above-mentioned problems. According to the present invention, in order to achieve the above object, an element whose one side is substantially rigid, an elastically deformable element spaced apart from the rigid element; a male element on the other side that can be introduced between the elements and an attachment device for preloading the elastically deformable element relative to said element in an elastically deformed state; It is characterized by According to this configuration, the male element is held between the rigid element and the elastically deformable element in a fixed state. When the attachment device is released, the elastically deformable element reopens elastically, which greatly simplifies disassembly. The elastically deformable element is provided with a generally conical countersunk recess configured to accommodate the head of the countersunk screw, and the apex angle of the cone of the countersunk recess is larger than the apex angle of the countersunk screw. Alternatively, the recess may be configured to deform toward the male element when the countersunk screw is tightened. This is advantageous because deformation in the vicinity of the countersunk screw ensures that there is no play in the connection between the elements. To release the connection, it can be easily disassembled by simply opening the spring device. Further, if the apex angle of the cone of the countersunk recess is made larger than the apex angle of the countersunk screw, and the recess is configured to deform into a male element when the countersunk screw is tightened,
For example, if the connection does not have to be disassembled again, the advantage arises that none of the elements have to be of elastically deformable construction.

The present invention will now be explained in more detail with reference to the illustrated embodiments. Note that the present invention is not limited to the following examples.

FIG. 1 shows a perspective view of an embodiment in which the present invention is applied to a frame 10 of a desk or drafting table. The desk frame 10 has two side parts 11,
12, which are joined to each other by horizontal connections 13. The shapes of the side parts 11 and 12 are the same, and in the illustrated embodiment are right triangles. Each triangle comprises a horizontal element 14, a vertical element 15 and an inclined element 16 extending from the front to the rear and forming the hypotenuse of said triangle. The horizontal element 14, as shown, serves as the base of the desk and is seated on the floor either directly or via adjustable feet. The vertical element 15 includes, for example, a West German patent application.
It is also possible to provide a conduit as described in German patent application No. P3509989.5, and the diagonally upwardly extending element 16 to be of hollow beam construction, as described in German patent application No. P3512201.3. Preferably, element 16 is provided with a height adjustment element. Although the structure described in West German patent applications P3509989.5 and P3512201.3 is incorporated into the illustrated embodiment,
Explanations about them will be omitted. Since the side part 12 has the same configuration as the side part 11, and the height adjustment devices on both sides operate integrally, the side part 12
Explanation regarding individual items will be omitted. Corresponding parts on the side part 12 are marked with 14', 15', and 15', respectively.
16' is attached.

It is also possible to change the form of the side parts 11 and 12,
For example, it is possible to have a trapezoid or a form without vertical elements, or instead of an open triangle, a triangle closed by side walls, or a so-called T-leg or L-leg (these terms will be used in the present specification). (defined at the end). The above deformed structures and other deformed structures are also included in the protection scope of the present invention.

Support members 1 are provided at the tops of the side parts 11 and 12, respectively.
7 and 18 are provided. As shown by the chain line in FIG. 1, a top portion 21 forming the top of the desk is mounted on the support members 17, 18. The top 21 is movable in the direction of the arrow 22 relative to the support members 17, 18 and by means of drive members 24, 24' as described in detail in West German patent application P3512201.3.
It is designed to move automatically only when the height is adjusted. In this way, when the height of the support members 17, 18 is adjusted, a horizontal movement is carried out at the same time, and the desk top 21 maintains a constant horizontal position relative to the user, i.e. the desk top 21
1, the top 21 moves only a small distance towards or away from the user. The support members 17, 18 are firmly connected to each other by rigid horizontal connecting members 30, 31.

According to the above structure, unlike a conventional desk, the desk top part 21 does not act as a part that firmly connects the two side parts 11 and 12, and the connecting part 13 is provided as the connecting part. It is necessary that the joint portion of the connecting portion 13 on the side portion 11 side can be removed for transportation. These removable joints must be sufficiently strong and at the same time allow for disassembly if necessary for transportation or repair.

FIG. 2 shows the rear side of the side part 12, that is, the vertical part 1.
5' is a front view. As shown in Figure 3, side part 1
2 is fixed with a rigid element 35 with a tip 35' projecting laterally from the side 12.
According to the illustrated embodiment, the elements 35 are arranged along a generally vertical plane. As is clear from FIGS. 2 and 3, four screw holes 36 are provided in the tip portion 35' at positions corresponding to the corners of an imaginary quadrangle.

Furthermore, an elastically movable channel element 37 is fixed to the side surface of the side part 12 closest to the connecting part 13. The vertical portion 38 of the element 37 extends parallel to the distal end 35' of the element 35, with a gap 41 having a width of approximately 2.5 mm, for example. Also, the gap 41 is an element 42 fitted therein (Fig. 5).
It is wider by, for example, 0.5mm. Furthermore, the element 37 is a horizontal part 4 that acts as a guiding element.
3,44 on the upper and lower parts.

On the side of the desk, elements 35, 37 are provided symmetrically, as shown in dashed lines on the left side of FIG.

In the portion 38, four holes 45 are arranged in parallel with the four holes 36.
It is provided to be consistent with the As shown in FIG. 5, the hole 45 has a very thin dish shape, and its apex angle β is set to, for example, about 120 degrees. These conical dish shapes do not reach the end of the hole 45;
There is a small portion left that is not dish-shaped.

Furthermore, each end of the male element 42, ie the connecting part 13, is provided with four holes 48 in each case. Hole 48
is aligned with the screw hole 36 in the inserted state, and also has a conical dish-shaped recess 50. Hollow 50
The apex angle α is smaller than the apex angle β, for example, 90 degrees.

As is clear from FIG. 7, the connecting portion 13 has a load-bearing structure portion 53. Structure 53 has a generally triangular cross-section and adjoins conduit 54 on the rear side. The conductor pipe 54 is connected to the horizontal wiring support section 5
It is divided by 5. Lower portion 56 of conduit 54
A cylindrical rod 57 is provided. The rod 57 is fixed by welding and rotatably supports a cover door 58 made of resin, which is shown by a chain line in FIG. This door 58 fits into a protrusion 59 on the upper part 60 of the conduit 54. The cover door 58 holds a rod 57 at its hinged opening, and if necessary, the door 58 can be easily pushed down to open the conductor tube 54 and allow access to the interior.

During assembly, the male element 42 or 42' of the coupling part 13 is inserted into the gap 41, respectively. The horizontal parts 43, 44 then act as guiding parts for the walls 56, 60 of the conductor tube 54, respectively, and guide the element 42 to the correct height. Note that other forms of horizontal guide means may also be used.

When the work of properly inserting the element 42 into the gap 41 is completed, the countersunk screw 60 is inserted through the holes 45 and 48 into the screw hole 3.
6 and tighten. Note that FIG. 5 shows the head of one screw 60. Also screw 6
Preferably, 0 is of the Allen thread type. As shown in FIG. 5, the apex or cone angle of the head of each screw 60 is approximately 90 degrees. That is, screw 6
The head apex angle of 0 is smaller than the angle β and approximately the same as the angle α, so the conical part of the hole 45 is deformed by the screw head and its inner edge is distorted toward the gap 41, resulting in the conical part of the element 42. Enter into the shaped cutout 50.
At the same time, the elastically deformable element 37
It is elastically deformed towards the 5' side to close the gap 41, thereby ensuring that the deformed inner edge of the hole 45 is fixed in the conical notch 50 of the hole 48.

The above fixing structure consists of four holes 4 on both sides of the connecting part 13.
8, so the connecting part 13 and the side part 1
A very strong load-bearing connection structure is formed between 1 and 12. However, when the screw 60 is removed, the portion 38 elastically returns to its original state and separates from the gap 41, making it possible to easily remove the above-mentioned connection structure.

Although this type of connection structure can be used with any other type of desk or table to take advantage of its advantages, as is clear from the above explanation, it is not suitable for use with desks such as the embodiment of the present invention. Particularly excellent effects can be obtained when

Furthermore, the parts can also be arranged in reverse, with the parts 35, 37 being provided on the connecting part 13 and the male elements 42 or 42' being provided on the sides 11, 12. Such modified structures are also included in the protection scope of the present invention. Note that the L-shaped leg refers to a type that is provided with side portions 11, 11 but not provided with inclined elements 16, 16. A T-shaped leg is an upside-down T-shaped leg.
It refers to a structure in which one vertical element is extended upward from each horizontal element 14, 14 in FIG. 1, and the corner of the desk top is supported by the vertical element.
