Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a structure for mounting a front panel of a record player or the like.

Structure of the conventional example and its problems The conventional example is shown in FIGS. 4 to 7, where 1 is a record player, 2 is a dust cover, 3 is a cabinet, and 4 is a front panel. Two stages of ribs 4c and 4d having round holes 4a and 4b (or approximately square holes) are provided on the back surface of the front panel 4, and the front panel 4 is provided at the bottom of the front surface of the cabinet 3 as shown in FIG. Round holes 4a, 4d provided in the ribs 4c, 4d of
Provide bosses 3a and 3d corresponding to the seventh
It was fixed with screws 5 as shown in the figure. In the figure,
6 is a power knob, 7 is an operation knob, 8 is a front decoration plate, 8a is a notch for fitting the operation knob 7, 9 is a printed circuit board, and 4e is a nail provided on the front panel 4 to fix the printed circuit board 9. be.

However, the above-mentioned conventional configuration has a major problem in that there are many screwed locations, which requires a large number of man-hours and increases costs.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned drawbacks of the conventional art, and aims to eliminate the need for screwed parts and to enable easy and reliable assembly.

Composition of the Invention In order to achieve the above object, the front panel attachment structure of the present invention provides ribs having holes at different front and rear positions on the upper and lower back surfaces of the front panel, and
The lower surface of the front end of the cabinet is provided with a convex portion that fits into the hole and a claw that engages with the lower surface of the rib on the lower side of the back surface of the front panel.

DESCRIPTION OF EMBODIMENTS The drawings (first
This will be explained based on FIGS.

In the figure, 10 is a front panel, and the upper part of the back surface of this front panel 10 is provided with a rib 10b having a substantially rectangular square hole 10a, and the lower part of the back surface is provided with a substantially rectangular square hole 10c and a rib 10b located within this square hole 10c. Rib 10e and printed circuit board 11 having recess 10d
A claw 10f for fixing is provided. Note that the square hole 1
0a is formed to be located in front of the square hole 10c. 12 is a front plate, which is printed etc. and has a design effect, and
It also serves as a cover for the hole formed during the formation of the square hole 10a, and is attached to the front panel 10 from the front. 12a is a notch for fitting the operating knob. Reference numeral 13 designates a cabinet, and a boss 13a that fits into the square hole 10a of the front panel 10 is provided on the lower surface of the front end of the cabinet.
and a convex portion 13b that fits into the square hole 10c of the front panel 10 and a rib 10 of the front panel 10.
A roughly arrow-shaped claw 13 that engages with the lower surface of the recess 10d of e.
A rib 13d having a diameter c is provided. Reference numeral 13e denotes a mechanism formed on both sides of the claw 13c, which is used to impart elasticity to the claw 13c when the recess 10d of the rib 10e of the front panel 10 engages with the claw 13c. 14 is the bottom plate, 11a is the printed circuit board 1
This is the lead wire connected to 1.

When assembling this embodiment configured as described above, as shown in FIGS. 3A, B, A', and B', the front panel 10 is moved upward from the bottom of the cabinet 13, and the square hole 10a is inserted. When the boss 13a, the square hole 10c, and the convex portion 13b are fitted, the substantially arrow-shaped pawl 13c engages with the lower surface of the concave portion 10d of the rib 10e due to the springiness generated by the vertical groove 13e. As a result, movement of the front panel 10 in the direction of arrow (A) in FIG.
Movement in the (b) direction is achieved by engagement between the lower surface of the concave portion 10d of the rib 10e and the approximately arrow-shaped pawl 13c, and movement in the direction of the arrow (c) is achieved by the engagement between the tip of the rib 13d [left and right of the convex portion 13b] and the square hole 10c. By joining the ribs around the arrow,
Movement in the (d) direction is suppressed by the connection between the rear end surface of the upper end of the front panel 10 and the front end surface of the cabinet 13.

Effects of the Invention As described above, according to the present invention, the front panel can be easily and reliably attached to the cabinet without using a single screw.
Significant reductions in man-hours and costs can be achieved.
