Abstract

(57) [Summary] [Purpose] Mount the panel to the chassis. [Structure] Using the elasticity of the substantially U-shaped panel, the mounting holes of the panel are engaged with the small protrusions on the top of the screw-fastening boss provided on the chassis so that the center position of the screw-fastening can be accurately placed. Construction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for attaching other parts to a plastic part such as an audio device and a toy.

[0002]

[Prior Art]

 The front panel of the audio equipment and the plastic chassis will be explained as an example. FIG. 5 shows a conventional example. Insert the panel 11 into the plastic chassis 12 by inserting it at the arrow B. The panel 11 has a mounting hole 13 and a hook engaging hole 14, and the corresponding chassis 12 is provided with a mounting boss 15 and a hook 16, respectively, and further, the screw hole 15a of the boss 15 has a hole 13a. In order to fix the panel so that it will not come off until it is screwed in, the chassis 12 has an elastic portion 17 of L-shaped plastic, and the hook 16 is engaged with the hole 14 by utilizing this elasticity. Was becoming.

[0003]

[Problems to be solved by the device]

 Since it is necessary to form the engaging hook part provided on the chassis side integrally with the chassis or to provide the same function with another part, the mold becomes complicated and the space loss for providing the hook part is lost. Also occurs. Furthermore, due to the warp in the front-back direction of the panel, there was a problem that the position of the mounting hole was changed.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned drawbacks, the present invention provides a small boss having an inclined portion having an ascending slope with respect to the insertion direction on the front pedestal surface of the mounting boss provided on the chassis, and has a substantially U-shaped cross section. The mounting hole is a hole that engages with this small projection, and the mounting structure is such that the small projection on the tip pedestal surface of the same boss and the mounting hole of the panel that engages with this are the positions of the mounting hole.

[0005]

[Action]

 In the process of attaching the substantially L-shaped panel to the chassis, the elasticity of the upper surface of the substantially U-shaped panel in the vertical direction is used to make the inclined surface provided on the small protrusion of the mounting boss tip pedestal portion provided on the chassis the panel. Moves in the direction of arrow A and is further pushed to engage the mounting hole formed in the engagement profile and the small projection engages to position.

【Example】

 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is an enlarged view of a mounting boss provided with small protrusions, FIG. 3 is a cross-sectional view of a screwed boss, and FIG. 4 is provided on a panel side. This is an example of a modified mounting hole. A chassis 2 to which the front panel 1 having a substantially U-shaped cross section is assembled is provided with a panel mounting boss 5, and a boss 6 having an inclination is provided on a pedestal portion of the boss tip. The front panel 1 has a mounting hole 3 at a position corresponding to the mounting boss 5 provided on the chassis 2. When the front panel 1 is inserted into the pedestal surface at the tip of the mounting boss 5 and pushed in, the cross section is substantially U-shaped. Due to the elasticity of the mounting boss 5, the tip pedestal of the mounting boss 5 slides into the small projection 6, and the engaging portion 4 provided in the mounting hole 3 engages with the chassis 2 to position the front panel 1. Therefore, the front panel 1 can be attached and fixed to the screw hole 7 provided at the center of the attachment boss 5 with the screw 8 through the attachment hole 3.

[0007]

[Effect of the device]

 Positioning can be easily done by pushing from one direction, and the position does not shift even if you release your hand, so you can screw in without any additional work such as positioning. You can use the automatic screwing machine with confidence.
