Description

  The present invention relates to a shelf mounting structure that allows a shelf board to be mounted while securing a storage space for a personal computer or the like between a pair of left and right columns in a fixture used in an office, a nurse station, or the like, and the shelf. The present invention relates to a fixture provided with a plate.

  In fixtures used in office spaces such as offices and nurse stations, shelves may be installed between the columns. In this case, a screw hole or an engagement hole is formed in the support column, and a mounting screw is screwed into the screw hole through an insertion hole provided in the bracket, or an engagement claw formed on the bracket is It is common to fix the brackets between the columns by fixing the brackets by engaging with the holes and fixing the shelf plates on top of the brackets.

  However, according to the above method, when the shelf board is removed, the plurality of locked portions provided on the support column are exposed to the outside, which not only takes time for processing but also deteriorates the appearance. was there.

  In addition, a fishtail-like groove that is wider at the back than the opening extending in the vertical direction is formed in the support column, and attached to the screw hole of the screw seat arranged in this fishtail-like groove through the insertion hole drilled in the bracket A method has been devised in which a screw is screwed and the edge of a fishtail groove is sandwiched between a screw seat and a bracket, thereby fixing the bracket and fixing a shelf plate on the upper part (for example, Patent Document 1).

However, in this method, when it is desired to install two shelf boards up and down by a predetermined size, a pair of brackets must be used for each shelf board, which is costly and relatively large. Not only does it require a work process, it has the problem of poor appearance.

According to the first aspect of the present invention, a storage space for a personal computer or the like can be easily secured by simply fixing both ends of the upper and lower shelf plates to the upper and lower pieces of the bracket, and the upper and lower shelves can be secured with one bracket. Since the plate can be supported, the structure is simple and the cost is low, and it is not necessary to provide the engagement hole or the screw hole in the support column, the screw is not exposed to the outside, and the appearance is good.
Moreover, it can be easily mounted at a desired height position while maintaining the interval between the upper and lower shelf boards.

  According to the second aspect of the present invention, the personal computer or the like housed in the space between the upper and lower shelf boards is not visible from the side, and the appearance is good.

  According to the third aspect of the present invention, since the mounting of the bracket can be easily performed, the workability during assembly and the change of the height position are easy.

  According to the fourth aspect of the present invention, the shelf board is stably supported without being displaced in the front-rear direction.

  According to invention of Claim 5, wiring between the upper direction and the downward direction of a shelf board can be performed easily.

  According to the invention described in claim 6, the office top plate and the space for accommodating the personal computer or the like can be formed simultaneously.

  According to the seventh aspect of the present invention, it is possible to easily perform power supply wiring from above the ceiling or the like to the fixture.

  According to the eighth aspect of the present invention, in order to increase the allowable movement distance of the fixture, even when wiring is performed using a long cord, extra wiring can be received by the wiring receiver.
