[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device having a cover, and more particularly to an electric device having a cover for covering an upper opening of a case for accommodating a dry battery.

[0002]

2. Description of the Related Art FIGS. 8A and 8B are side views of a conventional electric device. The side of the cabinet (2) is recessed one step to form a battery case (1), into which a plurality of dry batteries (9) (9) are inserted. The upper opening of the battery case (1) is covered with a lid (4). As is well known, a dry battery (9) is a compression spring (see FIG. 2) provided in a battery case (1).
Urged upward. The lid (4) has an outwardly projecting shaft (49) and a long hole formed in the side of the cabinet (2).
(29) is provided so as to be horizontally movable and rotatable. In the following description, the direction in which the lid (4) protrudes from the cabinet (2) is referred to as front, and the direction in which the cover (4) is retracted toward the cabinet (2) is referred to as rear. On the back of the lid (4), dry batteries (9)
A terminal plate (6) is provided in contact with the pole of (4), and a hook (40) is provided at a free end of the lid (4). The battery case (1) has a claw (1) which engages with the hook (40) at the closed position of the lid (4).
2) is standing. In order to close the opened lid (4) and engage the hook (40) and the claw (12), the lid (4) is once advanced, and as shown in FIG. The lid (4) is rotated downward about the shaft (49), and the hook (40) faces the front of the claw (12). When the lid (4) is retracted along the elongated hole (29), the hook (40) and the claw (12) engage as shown in FIG.
The lid (4) is locked to the cabinet (2).

[0003] Assuming that the opened lid (4) is a cabinet (2).
When the lid (4) is to be closed in a state of being retracted, the hook (40) hits the upper end of the claw (12) and the lid (4) cannot be locked to the cabinet (2). . Also, if the lid (4) is strongly closed, the hook (40) may collide with the claw (12) and damage the claw (12). In view of this point, a stopper piece (21) is provided on the cabinet (2) below the shaft (49) on the side of the rotational transition path of the lid (4) that has been advanced, and the lid is only provided in the advanced position. The device which cannot open and close the body (4) is made.
As shown in FIG. 8 (a), at the retracted position, the lower end of the lid (4) faces the stopper piece (21), and the lid (4) cannot rotate in the opening direction. In the forward position, as shown in FIG.
The lid (4) does not hit the stopper piece (21), and the lid (4) can be rotated in the opening and closing direction. However, even if an attempt is made to retract the opened lid (4), the lid (4) hits the stopper piece (21) and cannot be retracted. Since the lid (4) can be opened and closed only in the forward position, there is no danger that the hook (40) will hit the upper end of the claw (12) in the closed state, and the lid (4) will not be locked to the cabinet (2). The state can be prevented in advance.

[0004]

In a battery case (1) for accommodating a large number of dry batteries, a large number of dry batteries urge the terminal plate (6) upward at the closed position of the lid (4). Therefore, the lid (4) is easily lifted. The hook (40) and the claw (12) are engaged at the tip of the lid (4), but the shaft (49) fits into the long hole (29) of the cabinet (2) at the pivot. The lid (4) floats, so the lid (4)
Is easy to come off. Therefore, when the lid (4) is in the closed state,
Although it is necessary to prevent the pivot portion of (4) from lifting, if a new component is added to prevent the lifting of the lid (4), a space for disposing the component is required, and the configuration becomes complicated. SUMMARY OF THE INVENTION An object of the present invention is to prevent a pivotal portion of a lid from being lifted with a simple configuration in an electric device that opens and closes the lid after advancing the lid.

Therefore, the lid
Since (4) can be opened and closed only in the forward position, there is no possibility that the hook (40) will hit the upper end of the claw (12) in the closed state. As a result, it is possible to prevent a state in which the lid (4) and the cabinet (2) are not locked. During the rotation of the lid (4),
Although the second contact surface (44) may rub the stopper piece (21),
There is a problem that the user feels resistance to the rotation of the lid (4).

FIG. 7 is an enlarged sectional side view of a main part of the state where the cover (4) is completely opened. The second contact surface (4
One end of 4) abuts against the stopper piece 21 so that the lid 4 is prevented from rotating further. The battery storage opening (10) is exposed, and the batteries can be replaced. From the state of completion of opening of the lid (4), the lid
To close (4) and retreat, the operation reverse to the above may be performed.

In the present embodiment, both the operation of preventing the pivoting portion of the lid (4) from lifting and the operation of restricting the retraction of the lid (4) in the open state include the contact surfaces (43) and (44). This can be done on the cam surface (42). The cam surface (42) is formed in the vicinity of the pivotal portion of the lid (4), so that the lid (4) can be prevented from floating with a simple mechanism, and the lid (4) can be retracted in the open state. Regulations can be enforced. Furthermore, the holding piece (20) and the stopper piece (21)
Are located near the pivot of the lid (4) and can be provided close to the cabinet (2). Therefore, even if the holding pieces (20) are provided, the cabinet (2) is large. Does not change. Also, lock one of the mis-insertion prevention protrusions (50) with the lock lever.
(5) It is provided on the top, and the area on the lid (4) is effectively used. In other words, without increasing the size of the lid (4),
An erroneous insertion prevention protrusion (50) is provided.

A pivot (31) which is a center of rotation of the lid (4).
Protrudes inward from the lid (4), and
It is not visible from the outside of (2). Thereby, the appearance from the outside is improved. Conventionally, the axis of the lid (4)
(49) moves along the slot (29) in the cabinet (2)
When the lid (4) is slightly inclined, the shaft (49) is elongated.
The user may be caught on the periphery of (29) and may feel resistance when the cover (4) moves back and forth. However, in this example, since the lid (4) moves along the upper surface of the rotating member (3), the lid (4) is slightly inclined within the upper surface of the rotating member (3). There is no resistance when moving back and forth.

The description of the above embodiments is for the purpose of illustrating the present invention and should not be construed as limiting the invention described in the appended claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
