[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric device having a lid, and more particularly to an electric device having a lid that covers an opening of a case that houses a dry battery.
[0002]
[Prior art]
20 (a) and 20 (b) are side cross-sectional views of a conventional electric device. The side part of the cabinet (2) is lowered one step to form a battery case (1), and a plurality of dry batteries (9) (9) are inserted vertically into the battery case (1). The opening of the battery case (1) is covered with a lid (4). The dry batteries (9) and (9) are urged upward by a compression spring (90) provided in the battery case (1).
The pivot (31) projecting sideways from the base end of the lid (4) fits into the long hole (29) formed in the side of the cabinet (2), and the lid (4) is the battery case. (1) It is provided so as to be horizontally movable and rotatable on the top. In the following description, the direction in which the lid (4) protrudes outward from the cabinet (2) is defined as the front, and the direction in which the lid (4) is drawn into the cabinet (2) is defined as the rear.
[0003]
A terminal plate (6) in contact with the pole of the dry battery (9) is provided on the back surface of the lid (4), and a collar piece (40) is provided at the free end of the lid (4). The battery case (1) is provided with a claw piece (12) that is engaged with the collar piece (40) at the closed position of the lid (4). The lid (4) is locked to the cabinet (2) by the engagement, and the dry batteries (9) and (9) are urged by the spring (90) to push up the terminal plate (6) and the lid (4). The lid (4) is prevented from being detached from the cabinet (2).
[0004]
To open the lid (4), as shown in FIG. 20 (b), first, the lid (4) is advanced along the long hole (29), and the collar piece (40) and the claw piece (12) Release the locked state. Next, if the lid (4) is rotated upward about the pivot (31), the opening for inserting the dry batteries (9) (9) is exposed.
In order to close the lid (4) and engage the hook piece (40) and the claw piece (12), the lid (4) that has advanced is lowered and pivoted about the pivot (31), and the hook piece (40 ) In front of the nail piece (12). When the lid (4) is retracted along the long hole (29), as shown in FIG. 20 (a), the collar piece (40) and the claw piece (12) are engaged, and the lid (4) Is locked to the cabinet (2).
[0005]
[Problems to be solved by the invention]
In a conventional electric device, it is possible to move the lid (4) that has been moved forward and retracted in an open state. However, even if the retracted lid (4) is to be closed, the collar piece (40) hits the upper end of the claw piece (12), and the lid (4) cannot be locked to the cabinet (2). Further, if the lid (4) is closed strongly, the hook piece (40) may collide with the claw piece (12) and damage the claw piece (12). That is, there is a possibility that the members constituting the locking mechanism of the lid (4) collide with each other and the closed lid (4) is not locked.
In view of this point, the applicant has conceived that the lid (4) in the open state can be prevented from being retracted, thereby preventing the possibility of damaging the nail piece (12).
An object of the present invention is to accurately lock a lid in a closed state in an electrical device that retracts a lid that has been lowered into a closed state from an advanced position and locks the lid in a cabinet.
[0006]
[Means for solving the problems]
A locking mechanism is provided between the cabinet (2) and the lid (4) to prevent the lid (4) in the retracted position from opening. A support member (3) that rotates about the pivot (31) is provided inside the lid (4), and the lid (4) is provided on the support member (3) so as to be movable back and forth. Yes.
Electrical equipment
Provided between the lid (4) and the support member (3), the lid (4) or the support member (3) is locked in the open state of the lid (4), and the lid (4) A slide prevention mechanism for restricting the reverse movement of the pivoting portion (31) in the direction approaching the pivot portion (31);
The lid (4) or the cabinet (2) is provided on the lid (4), and the lid (4) is closed to release the locking of the slide prevention mechanism to the lid (4) or the support member (3). A release mechanism allowing the body (4) to retract in a direction approaching the pivot (31).
[0007]
[Action and effect]
When opening the closed lid When the lid (4) is in the retracted position, the locking mechanism engages the lid (4) and the cabinet (2) to open the lid (4). Prevents rotation. To open the lid (4), the lid (4) is moved away from the pivot (31), that is, moved forward to unlock the lid (4). The lid (4) pivots upward about the pivot (31).
When closing the opened lid When the lid (4) is open, the slide prevention mechanism locks the lid (4) or the support member (3), and the lid (4) is pivoted. Restrict movement to the direction approaching (31). That is, since the lid (4) in the open state cannot be retracted, there is no possibility that the members constituting the lock mechanism of the lid (4) collide with each other even if the lid (4) is rotated in the closing direction. .
When locking the lid that has been lowered to the closed state In the closed state of the lid (4) in the forward position, the release mechanism engages the lid (4) or the support member (3) with the slide prevention mechanism. The stopped state is released. The lid (4) can retreat on the support member (3), and the lid (4) is locked again.
Therefore, the lid (4) does not inadvertently retreat in the open state, so that even if the lid (4) is rotated in the closing direction, a lock mechanism for the lid (4) is configured. There is no risk of the members colliding with each other. Further, the lid (4) is correctly locked at the retracted position of the lid (4), and the lid (4) does not open carelessly.
