More specifically, the present invention can be easily attached to an indoor wall surface, and can be easily disassembled when the display is moved during moving work or the like. The present invention relates to a fixture that can be performed in a simple manner and that can minimize the volume of the fixture after disassembly.

  Due to recent technological innovations in plasma displays and liquid crystal displays, large-area and thin displays have been developed and marketed. Unlike the conventional floor-mounted display, these displays that have been rapidly spreading in recent years are attached to the wall surface of a house. Thereby, the area ratio which a display occupies in the living space of a house can be reduced.

Patent Literatures 1 to 3 propose a fixture used for mounting such a display.

It is composed of a shaped second frame and connecting rods (P17, P18, P19, P20) that connect the first frame and the second frame.
As is clear from FIG. 6, the structure of the fixture according to Patent Document 1 is very complicated and cannot be easily disassembled and assembled. In addition, the number of parts is large and the weight is large.

The fixture disclosed in Patent Literature 2 has a simplified structure of the fixture disclosed in Patent Literature 1. The fixture of Patent Document 2 includes a first plate (P21) fixed to the wall surface, a first frame body (P22) having a square shape in front view that is pivotally connected to the lower end of the first plate (P21), The first frame (P22) is substantially the same shape and size, and is composed of a second frame (P23) fixed to the front side of the first frame (P22).
It can be said that the fixture disclosed in Patent Document 2 has much fewer parts than the fixture disclosed in Patent Document 1 and is superior in terms of ease of disassembly. However, since each of the first plate (P21), the first frame (P22), and the second frame (P23) is composed of one member, the space volume occupied by the fixture at the time of disassembling is the same as when the fixture is assembled. Almost the same as the space volume occupied by the fixture.

The fixture disclosed in Patent Document 3 further has a simplified structure, and is formed by engaging and joining two plate members (P31, P32) having a rectangular shape in front view.
The fixture disclosed in Patent Document 3 has a further reduced number of parts and is further excellent in terms of ease of disassembly. However, similarly to the fixture disclosed in Patent Document 2, each component (P31, P32) is composed of a single member, and the space volume occupied by the fixture during disassembly is occupied by the fixture during assembly. Almost the same as the volume of space created.

  The work of removing and installing the indoor equipment when moving the indoor equipment when moving or the like is complicated, and the ease of removal and installation is required for the indoor equipment. In addition, the indoor equipment is required to be downsized when the indoor equipment is transported after being removed. These requirements also apply to display fixtures.

None of the display fixtures shown in FIGS. 6 to 8 sufficiently satisfy the above requirements.
As a result of diligent research, the present inventor has found that there is a problem of detachment and installation difficulty or non-reducibility of the display fixture according to the prior art in the technical idea shared by the prior art. .

  Wall-mounted displays such as plasma televisions and liquid crystal televisions have a rectangular shape in front view due to the nature and product specifications of the products, and the display fixtures according to the prior art are arranged along at least four corners of the display.

In order to ensure the movement of the vertical beam (P43, P44) along the horizontal beam (P41, P42), it is necessary to ensure the parallelism of the horizontal beam (P41, P42). Considering that this parallelism can be easily secured, a plate member having upper and lower edges raised as shown in FIG. 10 is prepared instead of the horizontal rails (P41, P42), and the raised portion of this plate member is prepared. A structure in which (P411, P421) is used as a rail member for parallel movement of the vertical bars (P43, P44) is conceivable.
However, in this method, similarly to the fixtures shown in FIGS. 7 and 8, there is a problem that the space volume occupied by the fixtures cannot be reduced when the fixtures are disassembled.

  As another method for solving the problem of parallelism, the horizontal beam (P42) arranged on the lower side is removed, and only the upper horizontal beam (P41) is used to guide the parallel movement of the vertical beam (P43, P44). The form to do is conceivable. However, according to this method, there is a possibility that the vertical beam (P43, P44) rotates about the connection point between the vertical beam (P43, P44) and the horizontal beam (P41). The problem is that the required strength cannot be secured.
