Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an articulated desk used in offices and conference rooms in offices.

[0002]

2. Description of the Related Art A desk having a desired top plate area can be obtained according to the size of an office or a conference room in an office, the number of employees, and the like. In many cases, a non-address method is used in which a user is arbitrarily divided and used according to the number of users and the contents of work.

[0003] The above-mentioned connected desk is disclosed in Japanese Patent Publication No. Hei 11-12486 (known example 1),
Japanese Patent No. 187128 (known example 2) is known.

In the case of the long connecting desk described in the above-mentioned known example 1, a beam member at the center in the front-back direction is attached to one end leg, and the beam members are sequentially connected. The connection top plate connected by the side plate is placed on the beam member sequentially from the end leg side, and finally the other end leg is connected to the beam member and the connection top plate, and the joint of each connection top plate is provided. (Seam)
The connection is made by inserting a dowel pin protruding at one end into a hole formed at the other end, and a connecting rod as a strength member is inserted through the front end of the top plate. The connection is made with a nut.

[0005] However, in the structure of the above-mentioned known example 1, since the assembling procedure is performed in order from one end, a temporary base for supporting the beam member is required. Before mounting on the member, it is necessary to connect the front and rear top plates to each other with the side plate, and in this state, the top plate is mounted on the beam member. Will be subjected to a large load.

For this reason, it is necessary that the beam members have more strength than necessary. Before the beam members are mounted on the beam members, the top plates are connected only by the side plates. When mounted on the top, the top plate and the side plates are easily deformed, and it is necessary to provide this portion with more strength than necessary.

[0007] As described above, it is necessary to provide each member with an unnecessarily high strength, so that there is a problem that costs are unnecessarily high. Further, when the top plate is mounted on the beam member, the top plate is connected in advance, so that the weight is large and the mounting work is not easy.

[0008] In view of the above, a known example 2 has been proposed to solve the above problems. In the known example 2, a top plate receiver is fixed on a self-supporting frame, a top plate is fixed on the top plate receiver to form a desk unit, and one end of the desk unit is provided with an end. A leg is provided, another desk unit is sequentially fixed and connected to the other end, and finally the other end leg is fixed. Jointing of the top plate of each desk unit is performed by fitting a knock pin and a hole in the same manner as in the above-mentioned known example 1, and a connecting rod is inserted into the front end side of the top plate as a strength member and connected with a nut. It has been made like that.

[0009]

However, the above known example 2
However, since the desk unit needs to be configured to be self-supporting, there is a limitation between the depth of the frame body and the depth of the top plate in order to stably stand alone. In other words, if you try to increase the depth of the top plate to obtain a wide top surface, you must inevitably increase the depth of the frame, and various depths are required to accommodate various uses of the articulated desk. It is necessary to arrange frames of various sizes according to the depth of the top plate when manufacturing a connecting desk of the size of, as a result, the number of types of parts increases, it is disadvantageous in terms of inventory, There is a problem that the cost is high.

Also, in assembling, since the desk units are sequentially connected in the horizontal direction, the desk unit consisting of the combination of the frame, the top plate receiving plate and the top plate must be moved. In addition, the burden on the user becomes extremely large, and in addition, since the adjacent top plates are placed on each frame-shaped desk unit, it is necessary to strictly adjust the level of each unit.

[0011] Furthermore, it is pointed out that the joints of the adjacent top plates are made by fitting the knock pins and the holes, so that the joints of the adjacent top plates are made closer to one top plate side of the joint portion. When a large load is applied to the pin, the hole and the knock pin in which the knock pin is fitted are deformed, and as a result, there is a problem that a step is easily generated in the joint portion and the repair is not easy.

[0012]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned various problems of the prior art, and the assembling work is simple, the burden on the worker is reduced, and the number of parts is small. It is possible to obtain a low-cost connected desk, and it is also possible to develop desks of various top sizes, making it difficult for steps to be formed at the joints between the top plates. However, it is intended to provide an articulated desk which can easily perform the repair.

And a connecting rod having a connecting rod having a connecting recess that allows an end of the connecting rod to be exposed on the joint lower surface of the top plate. A connecting nut is screwed into the thread of the connecting rod to make the connecting rods freely connectable, and an end nut is screwed into the thread at the outer end of the connecting rod to tighten freely,
After connecting the end leg and the intermediate leg adjacent thereto, the intermediate leg located at the middle and the end leg at the opposite end are connected, and a top plate receiver is mounted thereon, and the top plate is placed therebetween. The connecting rod ends are connected by connecting nuts in the connecting recesses at the joint surface lower surfaces of the joints, and the outer ends of the connecting rods are tightened by end nuts for assembling.

By connecting the side surfaces between the intermediate legs with a frame, closing the side surfaces with side plates, and ducting the inside between the side plates to provide a connection desk compatible with OA equipment.

A height adjusting gap is formed between the top plate receiver and the top plate, and an adjusting nut is inserted into this space portion in a non-rotating manner and inserted from the lower surface side of the top plate receiver. By screwing a height adjustment screw into the nut and making the height position of the top surface of the joint part of the top plate finely adjustable according to the screwing amount of the screw, the step generated at the joint part of the top plate after connection is reduced. It can be adjusted to eliminate it.

[0016] Further, if a locking member having a size matching the connection recess formed on the joint surface lower surface of the top plate and being engaged with a connection rod exposed in the recess is provided, the connection is established. The recess and the connecting nut inside it can be hidden, and the appearance can be adjusted.

[0037]

As described above, according to the present invention, when assembling the top plate to form a connection desk, first, the intermediate leg, the end legs, and the base portion of the so-called connection desk of the top plate receiver are assembled. Since the structure is such that the top plate is temporarily fixed and then the top plate is placed, only the minimum unit of each member needs to be carried at the time of assembling, and the assembling work can be performed extremely easily.

Even if the depth of the top plate is increased in order to obtain a large top plate surface, the base portion of the connecting desk is assembled first, so that the cable duct body including the frame between the intermediate legs is not unnecessarily increased. A stable connection desk can be obtained, which not only improves the safety during assembly work, but also allows the above-mentioned cable duct body, which functions as a cable duct, to be the smallest unit in the minimum unit. This is advantageous in terms of manufacturing and inventory, and can reduce costs.

Further, since the ends of the connecting rods for connecting the top plates are connected by connecting nuts in the connecting recesses formed in the joint lower surface of the joint of the top plate, an extra protrusion is provided on the lower surface of the top plate. There is no space at all, and the lower limb space can be sufficiently secured.

Further, since the intermediate top plate receiver has the left and right receiving plates, a step does not easily occur at the joint portion of the top plate, and it can be easily arranged on the same surface.

In addition, an interval for height adjustment is formed between the top plate receiver and the top plate, and an adjustment nut is inserted into this interval portion in a non-rotating manner, and If a height adjustment screw to be inserted from the lower surface side is screwed into the nut and the height position of the joint top surface of the top plate can be finely adjusted according to the screwing amount of the screw, if the top plate is temporarily assembled after assembly, Even if a step occurs at the joint, this can be easily eliminated. According to the fourth aspect, the height adjustment position can be arbitrarily selected within the range of the long hole, and further fine adjustment can be achieved.

If the cover is attached to the connecting recess, the recess is not exposed, so that the appearance can be improved. By adopting the main structure, the rigidity of the tabletop can be increased, and sufficiently stable support can be achieved even when the depth of the tabletop is large.
