Abstract

PURPOSE:To eliminate the need of a lead wire between the door device and a frame by providing a button of a door unit with a shaft for enabling the button to be rotational, an elastic part and a hinge for enabling a lever to be rotational and shifting the lever when the button is pressed and hence operating a tact switch outside a door. CONSTITUTION:The button of a button part housed in the door is projected out of a hole bored on a door operating surface, and when the button is pressed, the button is oscillated, and the lever integrated with the button and connected with the hinge is operated, and then the tact switch provided on a substrate fixed to the frame is operated. Then, when pressing the button is discontinued, restoring force of the elastic part fixed integrally with the end of this button is worked, so that the button is returned to its original position. Consequently, the door device is provided with a front panel 1, the door 2 and 2', a rotary shaft 3, the button 4, the shaft 5, the hinge 6, the elastic part 7, the lever 8, the frame 9, the substrate 10 and the tact switch 11. Thus, the value of utility is enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device with a switch operation button in an AV device or the like, and more particularly to a door device in which wire processing is eliminated from a switch kivan to improve assembly in a rotating door.

[0002]

2. Description of the Related Art In the structure of a conventional door device with operation buttons, for example, as shown in Japanese Utility Model Laid-Open No. 1-133385, a switch kiban is incorporated together with operation buttons. In such a conventional technique, no consideration has been given to the number of man-hours for processing the wire rod that connects the door portion and the device body.
This will be described below with reference to FIGS.

FIG. 5 is a perspective view when the door portion of the VTR is opened. In FIG. 5, 1 is a front panel which is a base, 2 is a door, and 3 is a front panel and a door for rotating the door. The rotary shafts 4 are buttons provided on the door, and constitute the front operation portion of each of these members VTR. FIG. 6 is a cross-sectional view of the button portion described above, and a door 2 is fixed to a front panel 1 shown in the same figure so as to be rotatable by a rotary shaft 3. The button 4 is exposed from the hole of the door 2, and the button 4 is fixed to the door 2 by a welded portion or the like via an elastic portion 7. In addition, a tact switch 11 and a kiban 10 to which the tact switch is soldered are also provided adjacent to the button 4. Kiban 10 and me
The bank 13 is electrically connected to the lead wire 12.

[0004]

In the conventional structure shown and described above, when the button 4 is pushed, the elastic portion 7 is bent and the tact switch 11 is pushed to turn on the switch. The electric signal is transmitted to the main van 13 via the lead wire 12. When the door 2 is closed (not shown), the door rotates about the rotary shaft 3 and the operation surface of the door is hidden. The lead wire 12 is longest when the door 2 is closed, and shortest when the door 2 is opened. Therefore, when the door is opened, the lead wire sags inside the front panel.
In addition, this may cause the door to open and close irregularly due to the opening and closing of the door and prevent it from opening and closing the door. It was Also, the door must first be fixed to the front panel during assembly,
When the front panel is attached to the frame 9, the lead wire 12 and the main van 13 must be connected so that the front panel and the frame are sufficiently close to each other. Since this can not be done for a long time, this work is very difficult to perform, and there is a drawback that it requires skill and requires many man-hours. The present invention has been made in view of the above points, and an object thereof is to operate a switch without attaching a lead wire to a door.

[0005]

In order to achieve the above object, the present invention operates the tact switch by fixing the tact switch and the kiban to the frame and transmitting the power of pushing the button of the door by the lever. The configuration.

[0006]

[Function] The button portion housed in the door protrudes from the hole formed in the operation surface of the door, and when this portion is pressed with a finger, the button vibrates and becomes integral with the button. A lever connected by a hinge moves and operates a tact switch on a kiban fixed to the frame. When you stop pressing the button, the restoring force of the elastic portion whose end is fixed to the door integrally with the button works and the button returns to its original position. At the same time, the lever also returns to the initial position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in FIGS. In this embodiment, V which is equivalent to that of the conventional example is used.
An example applied to TR is shown. In FIGS. 1 to 4, the same members and parts as those shown in FIG. 5 and FIG. The same components as are omitted to avoid duplication. FIG. 1 is a sectional view of a main part of a door device, a front panel and a frame. As shown in FIG. 1, doors 2 and 2'are held on a front panel 1 by a rotary shaft 3. Further, the door 2 rotates about the rotary shaft 3, which is in a range from substantially horizontal shown in FIG. 1 to about vertical shown in FIG. The operation surface of the door 2 is provided with a hole through which the button 4 projects. A button 4 is fixed to the door 2 by a shaft 5 so as to be rotatable. The button 4 and one end of the lever 8 are connected by a hinge 6 so that they can be interlocked.
Further, as shown in the perspective view of FIG. 4, the button 4 is integrally formed with an elastic portion 7. As described above, one end of the lever 8 is connected to the button 4 by a hinge, while the other end extends substantially linearly so that the door 2 can be projected from the door 2 through a part of the door 2. When the door of this part of the lever 8 is open, the tact switch 11 and the tact switch 11 are soldered so that the operation position of the switch is close to the frame 9. There is. When the switch is operated in a state in which it is completed as a device using the door device having the above-described structure, when the button 4 is pushed in the direction of arrow A with a finger as shown in FIG. 3, the elastic portion 7 of the button bends the button 4 Rotates. As a result, the lever 8 connected to the button 4 by the hinge 6 is pushed out to operate the tact switch 11. When the finger is released from the button 4, the elasticity of the elastic portion 7 causes the button to return to its original position. At the same time, the lever-8 also returns to its original position.

[0008]

As described above, according to the present invention, a lead wire is not required between the door device and the frame, and various troubles due to the lead wire shown in the conventional example are eliminated. Further, it is possible to provide a door device having cost advantages such as improved workability, and its practical value is great.
