Although b is provided on the side surfaces 3a and 3b of the substrate pieces 2a and 2b, the invention is not limited to this. The protrusion 5
If the positions a, 5b are avoided, the substrate pieces 2a, 2b may be cut out at appropriate positions to form cut grooves 6a, 6b. In short, when the push-down knobs 4a and 4b to be described later are pushed down, the substrate pieces 2a and 2b may be deformed and pushed down against the elastic force.

Next, the push-down knob will be described in detail.

As shown in FIG. 1, inside the coupling device 1, push-down knobs 4a and 4b are provided on the inward projecting pieces of the end portions of the two board pieces 2a and 2b. The push-down knob 4a, when viewed from the back side of the frame (that is, the state shown in FIG. 1), has one as a vertically raised knob vertical surface 4a1, whose apex is rounded and the other is an inverted arc-shaped inclined surface. And picked inclined surface 4a
The projection shape is 2. This is the push-down knob 4a
It has a shape that makes it easy to push down when pushing down with your fingertips.

Further, one of which is made vertical is the picking vertical surface 4
This is to prevent the fingertip from being applied to the front of a1 (that is, the direction of the corner of the coupling device). That is, the front of the knob vertical surface 4a1 has an end 31a of the frame frame 30a (for example, in the state of FIG. 3 or 4) which is being assembled or disassembled and has a sharp angle. This is to avoid danger. In addition, the vertical knob vertical surface 4a1 is formed in the fitting hole 3 of the frame frame 30a.
This is to ensure the fitting with 3a. In the above description, the push-down knob 4a has been described.

A flat surface is provided on the top of the projection vertical surface 5a1 toward the end of the substrate piece 2a to form a projection flat surface portion 5a3.
The protrusion shape is a protrusion inclined surface 5a2 that is inclined downward from a3. Although the above description has described the shape of the protrusion 5a, the same applies to the shape of the protrusion 5b.

The projection 5a is fitted in a fitting hole 33a formed in the frame frame 30a, and the connecting device 1 and the frame frame 30a are coupled and fixed. Details of the combination will be described later. The protrusion 5a and the fitting hole 33a
In FIG. 1, both have a quadrilateral shape when viewed from the back surface of the frame A, but are not limited to the quadrilateral. Any shape may be used as long as it can fit the projection and the fitting hole. For example, the protrusion is a cylinder with a spherical tip,
The fitting hole may be circular. In short, any shape that fits and fixes may be used. The above description is for the protrusion 5a and the fitting hole 3
3a has been described, the same applies to the protrusion 5b and the fitting hole 33b.

The material of the members constituting the connecting device 1 will be described. The substrate 2 and the side surfaces 3a and 3b may be integrally formed. In that case, it is appropriate to select a synthetic resin molded product. When it is inappropriate to integrally mold the both side surfaces 3a and 3b, a metal plate or a die-cast molded product such as an aluminum or zinc alloy is used, and the substrate 2 requires an elastic force. Made of stainless steel, synthetic resin molding, etc.
It may be attached to 3b by an appropriate assembly means such as screwing. In any case, it is necessary to take appropriate production means according to the size of the frame product, market size, etc.

Next, the frame frame will be described.

A fitting hole 33a for fitting with the projection 5a is formed, and an auxiliary hole 39a is formed in front of the fitting hole 33a (in the direction of the end 31a). The projection 5a is also fitted in the auxiliary hole 39a, but it is not fixed but is loosely fitted. This is to temporarily hold the connecting device 1 and the frame frame 30a during the assembling or releasing. This facilitates the assembly or release work. Details will be described later.

In addition, to explain additionally, the cross-sectional shape of the frame frame 30a is, as shown in FIG.
7a is provided. The upper holding piece 37a is provided with a holding groove 36a at a parallel position which is lowered by one step. A nipping groove edge 36a1 having a dent is provided in the portion forming the step,
On the opposite side, a holding groove edge 36a2 is formed which forms an end surface of the holding groove 36a and has a recess. The outer piece 51b of the back plate holder 50a is fitted to the sandwiching groove edges 36a1 and 36a2 having the depression. Details of fitting with the back plate holder 50a will be described later.

Further, explaining the material of the frame frame 30a, it is appropriate to select an extruded product such as stainless steel, synthetic resin or aluminum material.
The above description has described the shape of the frame frame 30a, the fitting between the protrusion 5a and the fitting hole 33a, and the fitting between the holding groove 36a and the outer piece 51b of the back plate holder 50a, but the same applies to the frame frame 30b. Is.

Next, the connection between the connecting device and the frame frame will be described.

In the following description, mainly the frame frame 3
The fitting between the frame 0b and the connecting device 1 will be described. However, the fitting between the frame frame 30b and the connecting device 1 is the same, and thus the description may be omitted. Below, an example of the procedure of combining is demonstrated.

As shown in FIGS. 1 to 6, first, the connecting device 1 and the frame frames 30a and 30b are placed as shown in FIG. 1 or 2. Next, as shown in FIG. 3, the frame frame 30 a on one side is inserted into the coupling device 1. Next, as shown in FIG. 3, the other frame frame 30b is inserted into the coupling device 1, and further inserted to the position shown in FIG. 4, and then, as shown in FIG. Picture frame 30
The end portions 31a and 31b of a and 30b are brought into contact with each other to form a predetermined angle α, and the assembly of this corner portion is completed. When the frame frame is sequentially inserted into the connecting devices at the respective corners, the assembling of the assembled frame is completed. When replacing the stored item 72, the above operation may be performed in reverse.

The details of the combination will be described below. In the groove 32a1 provided in the upper holding piece 37a of the frame frame 30a and the groove 32a2 provided in the lower holding piece 35a, the connecting device 1
When the side surface 3a of the end is inserted, at the position shown in FIG.
When 1a rides on the protrusion 5a and is sequentially inserted to the position shown in FIG. 4, the protrusion 5a is fitted into the auxiliary hole 39a and temporarily fixed. At this time, it will be loose fit. Further, when inserted, FIG.
As shown in FIG. 5, the protrusion 5a projects into and fits into the fitting hole 33a of the frame frame 30a. Then, the projection vertical surface 5a1 and the end surface of the fitting hole 33a come into contact with each other, and similarly, the frame frame 30b is fitted to the coupling device 1. However, in FIG. 3 and FIG. 4, the frame frame 30b has the protrusion 5 from the beginning.
b and the fitting hole 33b are in a fitted state. Then, the frame frames 30a and 30b have the end portions 31a,
The parts 31b come into contact with each other and join at a predetermined angle α. Further, since the fitting between the protrusion 5a and the fitting hole 33a can be easily observed from the upper surface on the back side of the assembled frame A, it can be easily discriminated whether or not the fitting is sufficient.

When the stored item 72 is replaced, the above work may be performed in reverse. Particularly, when the protrusion 5a is loosely fitted in the auxiliary hole 39a shown in FIG.
The a and the connecting device 1 are temporarily fixed. Similarly, the frame frame 30b and the connecting device 1 are temporarily fixed. Sequentially, when the frame frame and the connecting device are temporarily fixed to the other corners, all the corners are temporarily fixed. At this time, the stored item 72 may be replaced. As described above, in the replacement work of the stored items 72, it is not necessary to disassemble all the members, and the replacement work is facilitated.

Further, the end portions 31a and 31b of the frame frames 30a and 30b form a predetermined angle α in the coupled state. In the cases of FIGS. 1 to 5, the frame angle β is set to 45 degrees, so the predetermined angle α is 90 degrees. However, the predetermined angle α is not limited to 90 degrees.
In the case of a quadrilateral frame, it is generally considered to be set to 90 degrees, but in the case of a polygon, the predetermined angle or the predetermined angle of the frame frame of the deformed design is set to an appropriate angle. However, it is preferable that α = 2β. Also,
In the case of a quadrangle with a predetermined angle α = 90 degrees and a frame angle β = 45 degrees, the upper and lower sides of the frame frame are the same parts, and the left and right frame frames are the same, so common parts are used and production is performed at the same angle. There are merits such as sharing. Similarly, even in the case of a polygon, if α = 2β, it is possible to appropriately share the components.

The back plate holder 50b shown in FIG.
It fits into the frame frame 30b. Of course, although not shown, the back plate holder 50a is provided in the frame frame 30.
It also fits a. Details of fitting will be described later.
