Abstract

PURPOSE:To reduce the number of part items and improve the integrating property as the whole mechanism by providing a claw part, an elastic part and an operation part on a slide member formed from an elastic body. CONSTITUTION:A slide member 10 is formed of a claw part 11, an elastic part 12, and an operation part 13, which are integrally formed from a synthetic resin. The claw part 11 of the slide member 10 is fitted to the hole part 51 of an equipment body 50, and also engaged with projection part 52 of the body 50 to lock a battery. When the lock is released, the operation part 13 is slid in the arrowed direction, whereby the claw part 11 gets on the projection 52, and the claw part 11 is evacuated into the body 50 to release the lock.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery mounting structure in which a power source battery is directly externally attached to an electric device such as a video camera, and more specifically, the battery is locked and unlocked when the battery is replaced. The present invention relates to a battery lock mechanism.

[0002]

2. Description of the Related Art In recent years, in electrical equipment such as video cameras, a battery compartment for accommodating a battery is not specially provided in the body of the equipment, and the space of the battery compartment is reduced to reduce the size of the equipment. In order to simplify the attachment / detachment of the battery, a system in which the battery is exposed and attached to the outside of the device is often adopted.

6 to 9 schematically show such a battery mounting structure. Reference numeral 5 denotes an electric device main body, on one side of which a mounting portion 5a for slidingly fitting the battery 6 in the direction of the arrow is formed, and a claw portion 2a protrudes into the mounting portion 5a, and a hole portion 6a of the battery 6 is formed. The battery 6 is locked by the engagement of the claw portion 2a. 6b is a terminal portion of the battery 6. 6 is an upper perspective view of the battery 6 in a detached state, FIG. 7 is a lower perspective view thereof, FIG. 8 is an upper perspective view of the battery attached state, and FIG. 9 is a lower perspective view thereof.

On the other hand, when removing the battery 6, the claw portion 2a
Is performed by retracting the mechanism.
Shown in.

In FIG. 3, reference numeral 1 denotes a slide member that slides along with movement of the operating member, and reference numeral 2 denotes a lock / unlock of the battery 6 by inserting / removing the tip claw portion 2a into / from the mounting portion 5a. The claw member 3 for holding the claw member 2 is a support shaft for supporting the claw member 2, and 4 is a biasing spring for constantly biasing the claw member 2 in the protruding direction of the claw portion 2a. FIG.

Now, when the slide member 1 slides in the direction of the arrow along with the operating member, the claw member 2 is lifted by the slide member 1 and rotates about the support shaft 3 as shown in FIG. As a result, the claw portion 2a is housed in the device body 5 and the battery is unlocked.

[0007]

However, in the above-mentioned conventional example, basically, four parts of the slide member 1, the claw member 2, the support shaft 3, and the biasing spring 4 are indispensable, and the assembling direction of these parts is essential. However, it is difficult to improve workability because it is limited to one side.

In addition, in the claw member 2, a portion contacting the slide member 1 needs to have a certain thickness in consideration of accuracy and strength, and there is a possibility that a space for rotating the member becomes a dead space. was there.

[0009]

According to the present invention, a slide member made of an elastic body, having a claw portion protruding from a hole portion of a device body when a battery is locked, and sliding in a moving direction of a battery lock operating member. However, when it slides, it has elasticity because it has a structure in which the claw portion is retracted inside the device main body by riding on the projection provided on the device main body to unlock.
The member constitutes a battery lock mechanism.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 2 and 5 show an embodiment of a battery lock mechanism according to the present invention. FIG. 1 shows a battery lock (normal) and FIG. 2 shows a battery unlock.

Reference numeral 10 is a claw portion 11, an elastic portion 12, and an operating portion 13.
Is a slide member integrally formed of synthetic resin or the like, and is constantly urged to the lock position shown in FIG. 1 by a spring member (not shown), for example.

Reference numeral 50 denotes an apparatus main body having a hole portion 51 for projecting a claw portion and a projecting portion 52, and the claw portion 11 of the slide member 10 has an inclined surface portion which engages with the projecting portion 52. .

In the locked position shown in FIG. 1, the claw 11 of the slide member 10 projects through the hole 51 of the device body, and the claw 11 is the hole 6a of the battery 6 shown in FIG.
By engaging with, the battery is locked.

To unlock the lock, as shown in FIG. 2, when the operating portion 13 of the slide member 10 is slid in the unlocking direction, the claw portion 11 rides on the protrusion 52 of the device main body 50. As a result, the claw 11
Will be retracted into the device body 50, and the battery will be disengaged by the claw portion 11 and unlocked.

At this time, the displacement of the claw portion 11 in the projecting direction at the time of battery lock and battery unlock is caused by the elastic portion 12.
Absorbed by

[0016]

As described above, since the slide member made of the elastic body is provided with the claw portion, the elastic portion, and the operating portion, the battery lock mechanism is basically formed by one component except the main body. The number of parts is reduced and the workability of assembling the entire mechanism is improved.

Further, since the member does not rotate and the thickness of the elastic portion can be reduced, the dead space can be reduced and the product can be made compact.
