[Detailed description of the invention] (Field of industrial application) This invention relates to the opening/closing mechanism for doors installed in the operation buttons of electrical equipment such as televisions and VTRs, and is particularly concerned with opening/closing mechanisms that can be opened and closed using a push button operation. This relates to an opening/closing mechanism that can be opened and closed.

(Prior art) In electrical equipment such as televisions and VCRs, the operation buttons are generally not exposed directly and are closed with a door when not in use to prevent accidental touching of the operation buttons. .

Examples of such conventional door opening/closing mechanisms include those that open and close with a simple finger operation, and those that are equipped with a sliding lock mechanism.After locking or unlocking this lock mechanism with a finger operation, the door can be opened and closed using a simple finger operation. There are those that open and close with a finger operation, and those that are equipped with a magnetic lock mechanism and which release the magnetic lock by pressing a finger or the like and then perform the opening operation with a finger operation in the same manner as described above.

(Problems to be Solved by the Invention) The conventional door opening/closing mechanisms as described above require finger hooks to open/close, making them cumbersome to operate, especially the opening operation. There was a problem.

The purpose of this invention was to solve the problems of the conventional door opening/closing mechanism described above, and to provide a door opening/closing mechanism that can be opened with a push of a button and has excellent operability.

(Means for solving the problem) In order to achieve the above object, the door opening/closing mechanism according to this invention is attached to the opening of the case body so that it can be opened and closed by rotating around a rotation axis. The door is equipped with a push-lock mechanism in which the push rod is locked at the push operation position by a push operation from the protrusion position of the push rod, and is unlocked by a second push operation to return the push rod to the protrusion position. A push-lock switch is provided, the pivot shaft is disposed on the pushing end side of the push-rod, a pivot tongue is connected to the door and rotates in conjunction with the pivot of the door; A stopper piece corresponding to the rotating tongue piece is fixedly installed on the case body side, and when the push rod is in a locked state, the rotating tongue piece is released from the linkage with the stopper piece, and the door is in a closed state; When the push rod is returned to its original state by a re-push operation, a rotating tongue piece is linked to the stopper piece to rotate the door in the opening direction.

(Function) A push-lock mechanism is provided in which the push rod is locked at the push operation position of the push rod, and when the push rod is pushed again, the lock is released and the push rod returns to the initial protruding position. placed on the side,
The door is provided with a rotating tongue that rotates in conjunction with the rotation of the door, and the case body side is provided with a rotating tongue that opens the door in conjunction with the rotating tongue when the push rod returns due to a re-push operation. Since the stopper piece that rotates in the direction is fixed, when the door is in the closed state, the door can be automatically opened by simply pushing the push rod part. Conversely, when the door is open, if you push the push rod part, the door will be reliably locked.

(Example) An example of this invention will be described below based on the drawings. 1 to 3 are diagrams showing an embodiment in which this invention is applied to a door opening/closing mechanism disposed on the upper surface of a satellite receiver body.

First, the configuration will be described. A case body 2 is disposed on the upper surface of the chassis 1, and various operation buttons 3a, 3b, and 3c of the receiver are arranged inside the case body 2. A door 5 is disposed at the opening of the case body 2 and can be opened and closed by rotating around a rotating shaft 4 disposed at one end thereof. On the other hand, a push-lock switch S is provided on the back side of the case body 2 as an example of a push-lock mechanism. Reference numeral 6 denotes a mounting plate, by which the push-lock switch S is fixed to the chassis 1 side. 7 is the switch body, and 8 is the switch head. The push switch S is a well-known one, and the switch body 7
A push-lock mechanism (not shown) is installed inside the switch, and in the unlocked state, the switch head 8 is in the protruding position (FIG. 4C, which will be described later), and when the switch head 8 is pushed, the switch head 8 is locked in that push-operation position. Ru. If the push button is operated again in this state, the lock will be released and the switch head 8 will return to its original protruding position. In this embodiment, the push-lock mechanism of the push-lock switch S is utilized, and an arm 9 is connected to the switch head 8, and a bearing portion 9b is attached to the tip of the arm post 9a that is inserted through the case guide hole 2a. is formed in this bearing portion 9b,
The rotation shaft 4 is rotatably supported. Therefore, the rotation shaft 4 moves along with the push operation of the switch head 8 and the vertical movement of this switch head. Note that in this invention, the push rod refers to a switch head 8, an arm 9 connected thereto, and an arm post 9a that are integrated.

A rotating tongue piece 11 that rotates in conjunction with the rotation of the door 5 is connected to the back surface of the door 5. On the other hand, a stopper piece 12 is formed in the case body 2 at a position corresponding to the rotating tongue piece 11.
When the switch head 8 is pushed as will be described later, the stopper piece 12 moves to the rotating tongue piece 11.
When the push rod is released and the push rod returns to its original position by a second push operation, the door 5 is rotated in the opening direction in conjunction with the rotating tongue 11.

Next, the operation will be explained with reference to FIGS. 4A, B, and C.

When the switch head 8 is locked by the push lock mechanism by a push operation near the pivot shaft 4 of the door 5, the door 5 is in a closed state (FIG. 4A). At this time, a slight gap d is formed between the back surface of the door 5 and the opening edge 2b of the case body 2.

To open the door 5, push the door 5 again (B in the same figure). This re-push operation releases the lock state of the switch head 8 by the push lock mechanism, and the switch head 8, arm post 9a, etc. work together to return to the protruding position before the push operation. During this return operation, the rotating tongue piece 11 rotates about the rotating shaft 4 while contacting and interlocking with the stopper piece 12, as shown by the phantom lines in FIG. Be manipulated. Door 5 remains open even after opening operation
The rotation thereof is regulated by the stopper piece 12 and held in the open state.

When closing the door 5, reverse the above.
From the open state shown in Figure C, the door 5 is rotated in the direction of the arrow R in Figure C, and the switch head 8 is pushed to the position shown in Figure B via the arm post 9a. By this operation, the switch head 8 is locked by the push-lock mechanism, and the door 5 is closed in the state shown in FIG.

In addition, if a push-lock switch S is used as the push-lock mechanism as in this embodiment,
For example, the electric circuit opening/closing mechanism can be used to turn on the AFC circuit,
It can be used as an off switch,
The circuit can be switched on and off in conjunction with the opening and closing states of the door 5.

(Effects of the invention) As detailed above, according to this invention, the push rod is locked at the push operation position of the push rod, and when the push rod is pushed again, the lock is released and the push rod returns to the initial protruding position. The rotating shaft of the door is arranged on the pushing end side of the push rod, and the door is provided with a rotating tongue piece that rotates in conjunction with the rotation of the door, and on the other side of the case body there is a rotating tongue piece. Since a stopper piece is fixed that rotates the door in the opening direction in conjunction with the rotating tongue piece when the push rod is returned to its original position by the push button operation, when the door is in the closed position, all you need to do is push the push rod part. The door is automatically operated to open, and conversely, when the door is in the open state, the door can be reliably locked by simply pushing the push rod part.

In addition to the above-mentioned common effects, in addition to the above-mentioned common effects, according to an embodiment using the push-lock mechanism of a push-lock switch,
This push-lock switch is connected to a circuit that stops its function when the door is opened, such as AFC.
It can function as an ON/OFF switch for circuits, etc., and has the effect of opening/closing the door and turning ON/OFF the related circuits at the same time with just one push button operation.
