Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device case fixing device that is optimal for a small piggy bank or the like.

(B) Conventional technology When fixing a pair of cases made of synthetic resin, for example, it is desirable not to expose a fixing tool such as a screw on the surface of the case.
-35345 publication, especially as shown in FIGS. A holding body having a shape is provided, and the holding body is engaged with the engagement protrusion provided on the pair of cases.

However, in order to bring the abutting surfaces of the case into close contact with each other without any gap, it is necessary to increase the elastic force of the holding body and push the holding body apart to engage the holding body. It was a thing. Further, if the elastic force of the holding body is weakened and the engagement protrusion is easily engaged, there is a drawback that a gap is formed on the abutting surface of the case after assembling.

(C) Problems to be Solved by the Invention The present invention is to prevent a fixture such as a screw from being exposed on the surface of the case and to prevent a gap from being formed on the abutting surface of the case.

(D) Means for Solving the Problems In the present invention, at least the edges of a plurality of cases whose bottoms are opened are abutted against each other, and the openings are closed by a back cover to form a storage space for a contained object. A pair of engaging protrusions provided on the inner side wall near the respective edges of the case so as to face each other, a vertically elongated hole whose upper part of the opening width is narrowed by an inclined part, and a lower end of which is substantially parallel to the back cover. It has a fixing bracket with a bent fixing piece, and inserts the engaging protrusions into the vertically long holes, and screw the screw inserted through the back lid from the lower surface of the back lid to the fixing piece of the fixing bracket. By doing so, the fixing metal fitting is pulled down to press the inclined portion of the vertically elongated hole against the engaging projection, and the edges of the respective cases are abutted against each other, and at the same time, the back lid is fixed.

(E) Action The present invention is to engage the screws inserted from the lower surface of the back cover with the fixing metal fittings by tightening them and pulling down the fixing metal fittings downward, whereby the engaging projections of the cases where the inclined parts of the fixing metal fittings are adjacent to each other. And close the abutting surface of each case and fix the back cover at the same time.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an external perspective view. (1) is a pair of semi-circular cases (2
A money box comprising a cylindrical body (3) formed by combining A) and (2B) into a cylindrical shape, a case back (4) covering the lower part of the cylindrical body, and a hood (5) covering the upper part of the cylindrical body (3). Appliances consisting of (6)
Is a display for displaying the time set in the hood (5), the total amount of savings, the type of coins, etc., (7) is the lower outer wall of one of the cases (2A) and (2B). The operation part provided has a plurality of buttons (8A) ... (8D). (9) is a storage space for the stored objects (coins) formed by the cases (2A), (2B), the back cover (4) and the hood (5), and (10) is provided inside the hood (5) Coin sorting device for judging the type of coin, (11), (11)
Is an arm for decoration.

The cases (2A) and (2B) will be described in detail (see FIG. 2). (12A) and (12B) are a pair of engaging protrusions provided on the inner side wall near the respective edges of the cases (2A) and (2B) so as to face each other, and (13A) and (13B) are the engaging protrusions. (12A),
A pair of engaging protrusions provided in the same manner as (12B), (14) is a vertically long fixture, and the lower end is bent horizontally to provide a fixing piece (15). A vertically elongated hole (18) whose upper opening width is narrowed by inclined portions (16) and (17),
(19) is provided.

Then, the back cover (4) will be described in detail. (20) is an insertion hole formed on the outer peripheral side, and is set to be slightly wider than the width dimension of the fixing metal fitting (14). Reference numeral (21) is a lid plate that closes the insertion hole (20).

Next, the order of assembling the cases (2A), (2B) and the back cover (4) will be described. In the beginning, each case (2A), (2
B) end edges are abutted against each other and respective engaging protrusions (12A), (12B),
Move (13A) and (13B) closer together. In this state, the fixing metal fitting (14) is inserted through the insertion hole (20), and the engaging projections (12A), (12B) are inserted into the lower openings (18X) and (19X) of the vertically elongated holes (18) and (19). ), (13A) and (13B) are inserted, and the insertion hole (20) is closed with the lid plate (21) (see FIG. 3).
In this state, the screw (22) is inserted into the cover plate (21), screwed into the fixing piece (15) of the fixing metal fitting (14), and tightened. Then, the fixing metal fitting (14) is pulled down by tightening the screw (22), and the inclined portions (16) and (17) are engaged with the projections (12A) and (12B).
The engaging protrusions are pressed against each other by being pressed against the upper shoulders of (13A) and (13B), and the edges of the cases (2A) and (2B) are in close contact with each other.

(G) Effect of the Invention As described above, according to the present invention, the screw inserted from the lower surface of the back cover is screwed into the fixing metal fitting, and the fixing metal fitting is pulled down to press the inclined portion of the vertically long hole against the engaging protrusion of the case. Since the edges of the respective cases are abutted against each other and the back lid is fixed at the same time, the case and the back lid can be assembled at the same time, and the edges of the cases can be closely attached by the assembly. or,
The screws should not be exposed on the surface of the case and should have a smooth appearance.
