Description

[Detailed description of the invention] This invention allows the chassis mount to which the chassis is attached to be easily installed without using any mounting tools such as screws.
The idea is to make it removable.

Conventionally, for television receivers, etc., a chassis mount with a chassis attached was attached to the bottom plate of the cabinet using screws, but the installation was not easy and the chassis had to be pulled out for repairs and inspections. However, there is a disadvantage that it is difficult to remove the chassis.

The present invention aims to eliminate the above-mentioned drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 5, a chassis 2 is attached to a chassis mount 1 made of resin. A plurality of cross sections T protrude from the back surface of this chassis mounting base 1.
Projecting pieces 3 and 4 in the shape of a letter (not T or L may be used as long as there is a bent part at the lower end) are integrally provided. A plurality of pothole holes 6, 7 are provided in the bottom plate 5 of the cabinet, facing the protrusions 3, 4. Bottom plate 5
The pothole 7 near the rear end is configured to be open to the rear end of the bottom plate 5. A mounting bracket 8 made of resilient metal is fixed to the back surface of the bottom plate 5 in a cantilever shape with screws 9, facing the pothole 7. The free end of this mounting bracket 8 faces the rear end of the bottom plate 5. Moreover, the central part of the mounting bracket 8 is cut upward and becomes a cut-and-raised piece 11.
This cut and raised piece 11 is bent from the middle toward the rear end of the bottom plate 5 to form a bent piece 12.

When attaching the chassis mount 1 to the bottom plate 5, insert the protrusion 3 into the large-diameter portion 6a of the pothole 6, place the protrusion 4 on the bent piece 12, and bend the mounting bracket 8 while pushing the protrusion 4. Move it downward and position it in the large diameter part 7a of the potbell hole 7, then move the chassis mount 1 to the left and move the protrusions 3, 4 to the small diameter part 6 of the potbell hole 6, 7.
b, 7b, and the bent portion at the tip is brought into contact with the back surface of the bottom plate 5 to be in an engaged state. Then, the mounting bracket 8 returns to its original state, so the protruding piece 4 is attached with the cut and raised piece 11.
is held down, and the chassis mount 1 no longer moves. Finally, by inserting the lower end of the back plate of the cabinet between the bent piece 12 of the mounting bracket 8 and the bottom plate 10, the mounting bracket 8 will not bend even if force is applied.

As described above, according to the present invention, when attaching the chassis mounting base to the cabinet bottom plate, the bent part of the protrusion is inserted into the large diameter part of the pothole, and the rear protrusion is placed on the bent piece of the mounting bracket. While bending the free end of the mounting bracket, insert the protruding piece below the large diameter part, move the chassis mounting base toward the small diameter part, position the bent part of the protruding piece under the small diameter part, and then insert the protruding piece under the small diameter part. At the same time, the free end of the mounting bracket returns to its original position, and the protruding piece is held down by the cut and raised piece, and the chassis mount is completely locked and fixed in this state, so it is impossible to attach any mounting tools such as screws. The chassis mount can be easily attached to and removed from the cabinet without being used, and the mounting condition of the chassis mount can be maintained in good condition, preventing the chassis mount from accidentally falling off, improving assembly workability and service. It has excellent sexual effects. Furthermore, by inserting the lower end of the back plate of the cabinet between the bent piece of the mounting bracket and the bottom plate, the mounting bracket can be completely fixed without bending even when force is applied.

Claims (1)

[Scope of utility model registration request] A plurality of protrusions are provided that protrude from the lower surface of the chassis mount to which the chassis is attached and have a bent portion at the lower end, and pothole holes are formed in the bottom plate of the cabinet to which the chassis mount is attached in correspondence with the protrusions;
Form the pothole hole near the rear end of the bottom plate so that the large diameter part is open at the rear end, and attach the mounting bracket freely on the back side of the bottom plate, facing the pothole hole with the rear end open. Install it in a cantilevered manner so that the end faces the rear end of the bottom plate, and cut and bend the center part of this mounting bracket upward so that the cut and raised piece points toward the rear end of the mounting bracket from the middle. Fold it into a folded piece,
Insert the protrusion in front of the large diameter part of the pothole hole near the front end of the bottom plate, place the rear protrusion on the bent piece, and while bending the mounting bracket, insert the protrusion in the front. A chassis mounting device which is inserted into a small diameter portion of a potbelly hole, engages the protruding piece with the bottom plate, and presses the protruding piece with the cut and raised piece to fix the chassis mounting base.
