Description

[Detailed Description of the Invention] This invention relates to a reinforcing structure for a cabinet that allows upper, lower, left and right side plates and a baffle plate to be easily fixed to each other.

2. Description of the Related Art Conventionally, there is a cabinet shown in FIGS. 1 and 2 as a generally known cabinet. To explain the drawings, reference numeral 1 indicates upper, lower, left, and right rectangular side plates that are constituent plates of a cabinet body 5, which will be described later, with contact surfaces 1a having an inclination angle of 45° on three sides, and reference numeral 3 has an opening 4 for mounting a speaker. The baffle plate 5, which is a constituent plate of the cabinet body 5, has a contact surface 3a with an inclination angle of 45° on its periphery.A vinyl acetate resin adhesive 2 is applied to the contact surfaces 1a and 3a of the side plate 1 and the buffle plate 3, and the buff-full plate 5 is cured. The cabinet main body is assembled by pressing from the periphery with a tool so that each contact part forms a right angle, 6 is a corner board as a reinforcing fixing member provided in the cabinet main body 5, and side plates 1 of adjacent sides are assembled.
And it is fixed to the full board 3 using an adhesive 2 for reinforcement.

In the conventional reinforcement structure of the cabinet main body 5 as described above, in order to speed up the drying of the adhesive 2 applied to the contact surfaces 1a, 3a of the side plate 1 and the buttful plate 3 and the corner pieces 6, the surrounding environmental conditions, especially the sufficient Despite maintaining a suitable temperature, it takes a long time to proceed to the next process, and when removing the pressing jig, there are disadvantages in that insufficient drying can cause peeling and gaps.

This idea was made in order to eliminate the various drawbacks of the conventional cabinet reinforcement structure as described above, and instead of the conventional fixing member, a stopper piece that spans at least two adjacent component plates is used. By driving in a fixing member consisting of a concave sloped pawl that tightens toward the center of the stopper piece, the fixing strength is maintained, preventing peeling and the occurrence of gaps, and shortening the assembly time. The purpose is to

An example of this invention is shown below in Figures 3 to 6.
This will be explained based on the diagram.

Note that the same or equivalent parts as in the conventional example are given the same reference numerals.

In the figure, reference numeral 7 denotes a fixing member for fixing the two side plates 1, 1 and the buttful 3, and the stopper pieces 8 face in three directions while maintaining an angle of 120 degrees to each other.
It consists of Reference numeral 9 denotes a tapered claw portion formed at the lower outer end of the stopper piece 8, and 10 indicates a concave slope provided on the claw portion 9, which is constituted by a circular arc 11. 12
is a straight line with a sharp slope, and is located on the outside of the circular arc 11, and together with the circular arc 11 constitutes the claw portion 9. 13 is a fixing member for fixing the side plate 1 and the full plate 3 or the side plates 1 to each other;
It has a stopper piece 14 that faces in two directions at an angle of 180° with respect to each other, and its outer end is connected to the stopper piece 8 of the fixing member 7.
It has the same shape as the claw portion 9 formed in .

According to this invention, since the configuration described above is achieved, the contact surfaces of the side plate 1 and the full plate 3 are
Apply adhesive to a and 3a (see Figure 2 b and c),
Assemble by tightening from the periphery with a jig, and drive the fixing member 7 into the corner so that the three-way stopper piece 8 spans the two side plates 1, 1 and the full plate 3, and the stopper piece There is a resistance difference between the circular arc 11 provided on the claw part 9 of the part 8 and the linear slope 12, and the circular arc 11 with a large resistance pushes the side plates 1, 1 and the buttful plate 3 with a force corresponding to the resistance difference. It can be pulled in toward the center of the fixing member 7 and bitten into it to fix it.

Furthermore, when the fixing member 13 is driven into the corner so that the two-way stopper piece 14 straddles the side plates 1 and 1 or the side plate 1 and the buttful plate 3, the circular arc provided on the stopper piece 9 11 and the linear slope 12, and the circular arc 11 having a large resistance pulls the side plates 1, 1 or the side plates 1 and the buttful plate 3 into the center of the fixing member 13 with a force corresponding to the resistance difference. In this way, it can be bitten and fixed.

As mentioned above, this idea involves adhesively bonding the plates that make up the cabinet body to each other at a nearly right angle with the contact surfaces at approximately 45 degrees, and then fixing the adjacent component plates via the adhesive surface using a fixing member. In the structure for reinforcing a cabinet, the fixing member includes stopper pieces each spanning at least two adjacent component plates;
It consists of a claw portion formed tapered at the lower end of the retaining piece, and the inner slope of the claw portion is concave, so that when the fixing member is driven into the component plate, the component plate is placed at the center of the fixing member. The reinforced structure of the cabinet is characterized by tightening in one direction, so when removing the jig that tightens the surrounding area, even if the adhesive is not sufficiently dry, there is no risk of peeling of the component plates or creating gaps. Therefore, it is possible to shorten the assembly time.
