Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to doors in electrical equipment such as television receivers, radio receivers, and audio equipment.

In the electrical equipment described above, in order to hide the knobs for adjusting hue, brightness, sound quality, stereo left/right balance, etc. from the main body panel, a door is provided on the main body panel and the knobs are housed inside the door. The door can be opened and operated as needed.

In this case, the door is naturally made of the same color and material as the main body panel, so if a metal plate such as aluminum is used for the main body panel, the front of the door must also be made of the same type of metal plate. However, in this case, a resin back panel is required, which has a rotating shaft pivot and a locking piece for locking the door to the main body. Adhesives are usually used to integrate items made of different materials in this way, but if such adhesives are used, they may peel off after the fact, which is not good in terms of reliability.

This invention was made in view of these points,
The purpose is to provide a door in which the front panel and the back panel are fitted and fixed into one piece, thereby eliminating any problems in terms of reliability.

The present invention will be explained below with reference to examples. 1st
As shown in Figures 3 to 3, the door A is configured to open and close with respect to an aluminum main body panel 1 of an electrical device. The door A is the main body panel 1
Aluminum front panel 2 of the same color and quality as
and is integrated into the back side of the front panel 2.
It is assembled with a back panel 3 made of ABS resin. FIG. 5 is a diagram showing the front panel 2, with guide grooves 2a and 2b formed on the inside of both sides in the longitudinal direction of the back surface.
is formed, and a protrusion 2c shorter than the entire length is formed at the center in the longitudinal direction. FIG. 6 is a view showing the back panel 3, which has the same overall length as the front panel 2, and has protrusions on the longitudinal side edges to fit into the guide grooves 2a, 2b of the front panel 2. 3a and 3b are formed, and a grooved line 3c corresponding to the protruding line 2c of the front panel 2 is formed in the longitudinal center of the surface.
A slope 3d is formed on the right side of the grooved line 3c from the end face to the grooved line 3c, as shown in FIG. 6d. Also, at the left end portion of this back panel 3, a lock piece 4
A hole 3e is formed through which the lock piece 4 is inserted, and the lock piece 4 inserted therein from the front side has a flange 4a on the front side that comes into contact with a step 3f to prevent it from coming off to the back side. Another step 3 continuous to 3f
Spring 5 fitted from g to recess 3h
By pushing the lower part 4b, an elastic force is constantly applied upward (in the direction of arrow X). Further, on the back surface of the back panel 3, pivot shafts 3i and 3j are formed at the lower portions of both ends thereof, respectively, so as to protrude toward the end surface.

Then, with the lock piece 4 and the spring 5 fitted into the back panel 3, the front panel 2 is attached to the front side of the back panel 3, and the protrusions 3a, 3b are connected to the guide grooves 2a, 2b.
The back panel 3 and the front panel 2 are integrally assembled by inserting the back panel 3 and the front panel 2 from the end direction. In this case, the end of the protrusion 2c of the front panel 2 is inserted with the end resting on the slope 3d of the back panel 3, and the back panel 3 is slightly bent, but when the protrusion 2c is completely fitted into the groove 3c. The corners at both ends of the protruding strip 2c sink into the steps at both ends of the grooved strip 3c, and relative movement in the longitudinal direction is locked, and the back panel 3 and front panel 2 are completely integrated, and one door A is formed. becomes.

A mounting base 6 made of ABS resin as the main body is attached to the back side of the main body panel 1, and a recessed part 6a is formed in the part where the door A is attached, and an adjustment knob (not shown) is installed on the back side. It is exposed from the top to the front side.

In the door A, one pivot shaft 3j is inserted into the bearing hole 6b of the mounting base 6 with some play, and the other pivot shaft 3i is inserted into the bearing body 7 so that friction contact can be adjusted. By being attached to the attachment base 6, it can be attached to the attachment base 6 so as to be openable and closable.

The bearing body 7 has a substantially L-shape as shown in FIG. 4, and has a bearing hole 7a into which the pivot shaft 3i of the back panel 3 is inserted, and an adjustment hole 7b communicating with the bearing hole 7a. A mounting hole 7c for the mounting base 6 is formed at the back of this adjustment hole 7b. Note that the attachment hole 7c may be communicated with the adjustment hole 7b. Further, a stopper 7d for receiving the door A is formed on the front surface, and the stopper 7d is formed to receive the door A.
A hole 7e through which a push rod 8 for pushing the door A is inserted is formed in the lower part of the door d, penetrating between the front and back sides.
A locking protrusion 7f with which the locking piece 4 engages is formed at the upper corner of the front end of the locking member e. 7g is an engaging portion that engages with a corner 6d of the mounting base 6.

This bearing body 7 is attached to the mounting base 6 with a screw 9 with the pivot shaft 3i of the door A inserted into the bearing hole 7a. The screw 9 is sufficiently large relative to its diameter, so that the screw 9 can be screwed into the screw hole 6c of the mounting base 6.

By adjusting the tightness of this screw 9, the vertical distance between the adjustment holes 7b can be widened or narrowed, so the diameter of the bearing hole 7a can be adjusted. The frictional contact force with the pivot shaft 3i can be adjusted. That is, the feel of the hand when opening and closing the door A can be adjusted.

Reference numeral 10 denotes a door release button, which penetrates through the mounting base 6 and the front panel 1, projects to the front, and is stopped at a collar portion 10a. 11 is a lever that rotates around a shaft 12 and pushes the push rod 8 forward when the door release button 10 is pressed;
The door release button 10 is pushed out by a spring 13 at all times. Note that the lever 11 is engaged with the push rod 8 with some play.

In the above, the door A rotates and closes when pushed from the front, and at this time, the locking piece 4 engages with the locking protrusion 7f of the bearing body 7 with an elastic force, so that the closed state is maintained. be done. Further, when the door release button 10 is pressed, the lever 11 rotates and the push rod 8 pushes the door A from the back, so that the locking piece 4 and the locking protrusion 7f are disengaged and opened forward. After that, it can be completely opened by hand. As described above, the feel in this case can be adjusted using the screw 9.

In the embodiment described above, the front panel 2 has the protrusion 2c, and the back panel 3 has the concave protrusion 3.
c, and the projections 2c and grooves 3c are fitted together to lock and integrate the two, but the projections are provided on the back panel 3, and the grooves are provided on the front panel 2. A similar integration can be achieved with not only protrusions and recesses, but also simple protrusions and recesses.

As described above, according to the present invention, the back panel is completely and stably integrated with the front panel, and there is no fear of peeling off due to aging. Also, the parts of the back panel excluding the pivot points are the front panel 2.
Since it is completely hidden from view, the homogeneous design of the main body panel and front panel will not be disrupted.
