Description

[Detailed Description of the Invention] This invention relates to a door switch device suitable for television receivers and the like.

Door switch devices that switch and drive predetermined operations of electrical equipment in relation to the opening and closing of the door of the equipment body have conventionally been used.
Various types are known.

By the way, for example, the AFT of a television receiver
For door switches that may be left inactive for long periods of time due to internal adjustments, etc., the switch should be able to operate independently from the door as needed, for example by keeping the door long to prevent the switch from operating. It would be desirable to eliminate the hassle of having to keep it open for hours.

For this reason, conventionally, for example, as shown in FIG. 1, the driver 3 of the switch 2 provided in the main body 1 of the device is made short so that it does not come into contact with the door 4, and the tip of the driver 3 is placed so that it can be pressed when the door 4 is closed. Knob 5 in the position to be moved
is attached removably, and normally the switch 2 responds to the opening/closing operation of the door 4 via this knob 5, and when necessary, the switch 2 can be made independent from the door 4 by removing the knob 5. Are known.

However, in this case, since the knob 5 is removed from its regular position and moved to another location, the removed knob 5 is often lost over a long period of time, which is extremely inconvenient in handling.

This invention has been made in view of such circumstances, and aims to provide a door switch device that is easy to handle and does not cause inconveniences such as loss.

An embodiment of this invention will be described below with reference to FIG.

A hinge body 8 is provided on the inner surface of a door body 7 that is attached to a device body 6 so as to be openable and closable. This hinge body 8
has a hinge part 9 whose central part is bent in two and can freely protrude toward the device body 6 side, one end of which is fixed to the inner surface of the door body 7 via screws 10, and the other end is fixed to the inside of the door body 7. Stopper 1 provided on the inner surface of body 7
1, the hinge portion 9 is bent to be releasably engaged. In other words, this hinge body 8 is located on the inner surface of the door body 7, and the other end is connected to the stopper 11.
When the hinge part 9 is engaged with the stopper 11, the hinge part 9 protrudes toward the device body 6, and when it is removed from the stopper 11, the hinge part 9 is engaged with the door body 7.
I try to keep it flat on the side. The switch 12 is provided on the device body 6 so that the driver 13 faces the inner surface of the door 7 when the door 7 is closed, and the driver 13 of the switch 12 is in a protruding state. The hinge part 9 is brought into contact with and pressed only when the door body 7 is closed, so that the switch 12 is driven when the door body 7 is closed.

With such a configuration, normally the other end of the hinge body 8 is locked to the stopper 11 and the hinge part 9 is kept in a protruding state, so that the switch can be switched in accordance with the opening and closing of the door body 7. can be done.

Furthermore, if the other end of the hinge body 8 is removed from the stopper 11 and the hinge part 9 is laid flat (the state shown by the two-dot chain line), the drive element 33 will not contact the hinge part 9 even when the door body 7 is closed. , even if the switch 12 opens or closes the door body 7, it will not be driven.

Therefore, the switch 12 can be easily made independent of the door body 7 by simply engaging and disengaging the hinge body 8 from the stopper and changing the central hinge part 9 between the protruding state and the non-protruding state. body 8
Since the shape only changes in a fixed position, there is no risk of losing it, unlike conventional knobs that can be removed, making it convenient to make adjustments over a long period of time, for example. .

Note that this invention is not limited to that shown in the above embodiment, but can also be implemented in the form shown in FIG. 3, for example.
That is, a hinge body 8a is formed integrally with the door body 7a by partially projecting the door body 7a toward the inner surface side in a frame shape, and this hinge body 8a is elastically curved in a concave-convex shape in the center. It may also have a toggle spring-like hinge portion 9a.

Even with such a configuration, simply by pressing the hinge portion 9a with a force greater than a predetermined value and changing the direction of the unevenness, the hinge portion 9a can be brought into contact with the drive element 13 of the switch (the state shown by the solid line) and separated. Since it can be adjusted to the state shown by the two-dot chain line, the switch can be made independent from the door body with simple operation and without the risk of loss.

In addition, the structure shown in FIG. 3 has the door body 7.
By providing the name plate 14 on the front surface of the hinge body 8a, the hinge body 8a can be closed off from the outside. Further, the hinge portion 9a may be formed integrally with the hinge body 8a, or may be constructed by supporting a separate elastic plate on the hinge body 8a, and various modifications are possible.
