Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a door mounting device such as a video tape recorder.

(B) Conventional Technology Various door mounting devices have been proposed, but they have drawbacks such as difficulty in mounting, complicated structure, and large number of parts.

(C) Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks, and in particular, the lid can be attached and detached only when the door is opened at a specific angle. It is designed so that it cannot be removed in the state.

(D) Means for Solving the Problems In the present invention, the first and second support shafts formed at both ends of the door are connected to the first and second bearing portions having the through holes formed in the device body. A coil spring that rotatably supports the door with respect to the main body of the device by inserting the coil spring and that biases the door in the second support shaft direction and the closing direction is attached to the first support shaft.
The tip of the first support shaft is composed of a small-diameter portion and a large-diameter portion following the small-diameter portion, and a cutout portion is provided in a part of the large-diameter portion. Further, the through hole of the first bearing portion corresponding to the first support shaft is a long hole, and when the notch direction of the large diameter portion of the support shaft coincides with the direction of the long hole, the through hole extends to the large diameter portion of the support shaft. In other cases, only the small diameter portion can be inserted into the through hole.

Further, the notch direction of the large-diameter portion of the support shaft and the direction of the long hole coincide with each other when the door is opened by about 45 degrees.

(E) Operation According to the above configuration, when the door is tilted about 45 degrees with respect to the main body of the device, the tip of the first support shaft reaches the large-diameter portion of the first bearing portion against the urging force of the coil spring. When the door is inserted into the hole and then the door is shifted toward the second bearing portion and the hand is released, the door is moved toward the second bearing portion by the biasing force of the coil spring and is closed. And in this state, the first door,
The second support shafts are respectively supported by the first and second bearing portions,
It can be opened and closed.

In order to remove the door, it does not come off unless the door is pushed in the direction of the first support shaft in a state where the door is opened at about 45 degrees. That is, when this door is opened at about 45 degrees,
The door is displaceable in the supporting shaft direction. In other words, the large diameter part of the first supporting shaft can be inserted into the elongated hole of the first through hole, and the supporting shaft of the door can be removed from the bearing part. In other cases, the large diameter portion of the first support shaft abuts the through hole of the bearing portion to prevent axial displacement, so the door cannot be removed.

(F) Embodiment In FIG. 1, the first bearing 2 is provided to the first bearing portion 2 and the second bearing portion 3 provided in the panel 1 of the device main body, and the first bearing of the door 5 is provided to the through hole (not shown) provided in the second bearing portion 3. The support shaft 6 and the second support shaft 7 are inserted. The door 5 covers the window portion 4 formed on the panel 1. First
A coil spring 8 is inserted in the support shaft 6 to bias the door 5 in the second support shaft 7 direction and the closing direction.

The through hole 2a of the first bearing portion 2 is a long hole (see FIG. 2). The first support shaft 6 is composed of a small diameter portion 6a and a large diameter portion 6b following the small diameter portion 6a. The large diameter portion 6b has a cutout portion 6c. When this notch direction coincides with the long hole direction of the through hole 2a, up to the large diameter portion 6b of the first support shaft 6 is inserted into the through hole 2a, but in other cases, only up to the small diameter portion 6a. It cannot be inserted.

The tip end of the second support shaft side is inserted into the through hole of the second bearing portion 3 and is rotatably supported.

In the closed state of the door 5 shown in FIG. 3a and the opened state shown in FIG. 3b, the large diameter portion 6b of the first support shaft 6 is in contact with the through hole 2a. No. 5 cannot be displaced in the axial direction. In the state shown in FIG. 3c, the notch direction of the large diameter portion 6b of the first support shaft 6 coincides with the elongated hole direction of the through hole 2a,
This is a state in which the large diameter portion 6b of the first support shaft 6 can be inserted into the through hole 2a, that is, the door 5 can be displaced in the axial direction. In this state, the door 5 can be attached and detached.
In addition, in order to prevent the door 5 from being unintentionally removed when the panel 5 is attached to the device body in a state where the door 5 is opened approximately 45 degrees, the inside of the device body is provided near the door 5 opened approximately 45 degrees. A mechanism may be provided to prevent axial displacement of the door 5.

(G) Effect of the Invention According to the present invention described above, the door can be easily attached without using screws and the door can be removed by
Since it cannot be removed unless the door is displaced in the axial direction when it is opened approximately 45 degrees, accidental removal of the door can be reliably prevented.
