Description

  The present invention relates to an assembling desk, and more particularly to an assembling desk with a knock-down method and lateral expansion.

  Conventionally, it is composed of an end leg, an intermediate leg, a connecting member that connects between the end leg, and a top plate. The assembly type has a structure in which the top plate is continuously connected to the side through the intermediate leg one after another at the same distance between the legs. Various desks are provided. For example, Patent Document 1 discloses an assembly type of a structure in which an outer leg and an intermediate leg are connected by a connecting frame, and the outer leg and the intermediate leg are connected in a state where the top board is placed on the top board support arm. The desk is disclosed. Here, the outer leg has a top plate support arm at the top and a grounding leg at the bottom, and the intermediate leg has two rows of top plate support arms and has no structure. . In other words, the intermediate leg is provided with two same top plate support arms as the top plate support arm of the outer leg side by side, so it has a width twice the lateral width of the outer leg, and the distance between the legs is reduced by the connecting frame. It is possible to connect a plurality of top plates to the side while keeping the same. Furthermore, the outer leg and the intermediate leg are connected to the connecting frame by engaging the hook provided at the lower part of the end face of the connecting frame with the engaging hole formed in the side of the leg, and the mounting hole provided at the upper part of the leg. It is described that it is screwed into the upper screw hole.

Even in this kind of assembling desk that can be connected to the side, the top plate with edge processing on both side edges is shared for both the end and the middle. However, when connecting a plurality of top plates with edge processing on both side edges, the edge portions overlap at the joints between adjacent top plates, discontinuities occur, and joints are formed, resulting in a sense of unity as the top plate. Become scarce.

Moreover, the thing of FIG. 1 of patent document 2 attaches and integrates the intermediate leg of the same shape on both ends of a flame | frame so that the top plate of the same width can be used, and it is the same width as it. The top plate is attached and modularized, and a plurality of units are connected as a unit to ensure equal pitch conditions. Therefore, the end legs are connected to the outside of the intermediate leg located at the end, and the end A so-called side winning structure in which the side edge of the top plate is joined to the inner surface side of the leg cannot be unavoidable, and since the structure has two intermediate legs overlapped at the intermediate part, the appearance becomes heavy. On the other hand, the thing of FIG. 10 of patent document 2 uses the thing which becomes a width twice as large as a top-plate holder for an end as an intermediate leg, connects each leg directly with the same flame | frame, and distance between legs. However, when three top plates are arranged using two intermediate legs, the width of the top plate provided between the two intermediate legs is set to be larger than the width of the top plate at both ends. There is an inconvenience that it is necessary to increase the width of the support.
