Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an assembly desk which is carried into a place of use in a substantially disassembled state and is assembled and used at this place of use.

[Conventional technology]

Conventionally, in the field of office desks and the like, in order to improve transportation efficiency, it is generally performed that the product is delivered to a purchaser in a substantially disassembled state, and then the purchaser or the seller assembles and completes it. As such an assembly desk,
As shown in the figure, in general, a pair of side plates a and b, a back plate c,
It is known that a top plate d is disassembled and these are connected to each other to be assembled.

[Problems to be solved by the device]

In the above conventional assembly desk, to assemble it,
Since the side plates a and b do not stand alone, for example, one worker supports the pair of side plates a and b in an upright state, and another worker holds the back plate c at a predetermined position of the side plates a and b. Hold and hold. Still another worker attaches the back plate c to the back side of the side plates a and b with screws or the like. As a result, the pair of side plates a and b and the back plate c are integrated and self-standing, and then the top plate d is attached on them to complete the assembly.
In the above-mentioned assembly work, regarding the attachment of the back plate c,
For example, by using an appropriate jig and tool, it may be possible to allow an operator supporting the back plate c to perform the work together.
However, even in that case, at least two workers are required for the assembly work.

Therefore, conventionally, there has been a demand for the development of an assembly desk that can be assembled by one person. It should be noted that it is conceivable to connect the pair of side plates a and b and the back plate c to each other in advance, but this would be bulky during transportation, and the meaning of constructing the desk in an assembled manner would be meaningless.

The present invention has been made in order to solve such a conventional problem, and can be made into a compact form during transportation, and at the time of assembling, it can be assembled easily and surely by one person. It is intended to provide a desk.

[Means for Solving the Problems]
