Abstract

PURPOSE:To only insert and press a battery cover into an enclosure and to surely lock the battery cover to the enclosure by providing the battery cover with a slide projection and a stopper part and providing a lock mechanism on the side face of the enclosure for the purpose of locking this stopper part. CONSTITUTION:A slide projection 2A of a battery cover 2 is inserted to a slide groove 1A and pressed in the direction of an arrow A. Though a lock claw 3A of the battery cover 2 is brought into contact with a stopper wall 1E of an enclosure 1, the lock claw 3A is raised by the slope of the lock claw 3A. When the slide projection is pressed in the direction of the arrow A furthermore, the lock claw 3A goes over the stopper wall 1E and is pushed out by a spring 3D, and the front end of the lock claw 3A is dropped into a recessed part 1F to retain the battery cover 2. At this time, slipping-off of the battery cover 2 is prevented by the lock claw 3A and the stopper wall 1E though a pushing-out spring 4 is brought into contact with a spring receiver 3E of the battery cover 2 to push the battery cover 2.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an individual paging receiver,
In particular, the present invention relates to a mechanism for attaching and detaching a battery cover in an individual paging receiver.

(Prior Art) Conventionally, this type of individual paging receiver uses a rechargeable battery or a dry cell battery, but when replacing the dry cell battery, it is necessary to remove the battery cover.

A conventional example is shown in FIG. 4. In FIG. 4, 41 is a housing of an individual call receiver, 42 is a battery cover, 43 is a fastening part of the battery cover 42, and 41D is an engagement part that engages with the fastening part 43. Department. The battery lid 42 is attached by having one end 42A engaged with the housing 41 from the direction of arrow E, and the fastening part 43 provided at the other end of the battery lid 42 and the engaging part 41D of the housing each having elasticity. was.

(Problem to be solved by the invention) However, since batteries are replaced by ordinary users,
There are many cases where the battery cover is lost because the lid is not completely tightened after replacing the battery, or because the user forgets to lock it.
This poses a major problem for users and administrators of the devices.

The present invention solves these problems.

Even if the user does not handle the battery cover very well, the battery cover does not need to be taken very seriously when attached, and after the battery cover is attached, it is secure and does not fall off.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an individual paging receiver in which a battery is installed in the housing, and a slide groove provided along the housing, and a combination with the slide groove. The battery cover includes a sliding protrusion and a stopper portion, a locking mechanism provided on the side surface of the casing for locking the stopper portion, and a drive mechanism for releasing the lock.

(Usage) Therefore, according to the present invention, since a locking mechanism for the battery cover is provided, a user who is inexperienced in installing a battery can simply push it in fully without paying any special attention. This completely locks the cover to prevent the battery cover from falling off due to careless operation.

(Embodiment) FIGS. 1 and 2 show the structure of an embodiment of the present invention.

In Figures 1 and 2, 1 is the case of the individual calling receiver, 2 is an L-shaped battery cover, LA is a slide groove for inserting the battery cover 2 from the long direction, and IB is a battery terminal. Wall, IC, 10 are battery terminals.

2A is a slide protrusion that fits into the slide groove IA of the housing 1, and the battery cover 2 is inserted from the direction of arrow A.
is a hook. 3 is a drive part of a lid stopper provided on the battery cover 2, 3A is a lock claw of the battery cover 2 that locks to the stopper wall IE of the housing 1 provided on the drive part, 3B, 3G
3E is a spring holder for the battery cover 2, 4 is an extrusion spring for the battery cover 2, 5 is a battery, and 5A is a battery terminal.

The operation in the embodiment of the present invention will be explained based on FIGS. 1 and 2.

Insert the slide protrusion 2A of the battery cover 2 into the slide groove IA and push it in the direction of arrow A. The lock claw 3A of the battery cover 2 hits the stopper wall IE of the housing 1.

The locking claw 3A is pushed up by the inclined surface of the locking claw 3A. Here, when the lock claw 3A is further pushed in the direction of arrow A, the lock claw 3A is pushed out by the spring 3D when it passes the stopper wall IE.

The tip of the lock claw 3A falls into the recess IF and presses the battery cover 2. At this time, the extrusion spring 4 is attached to the spring holder 3E of the battery cover 2.
At this time, the battery cover 2 is pushed out, but it is prevented from being pulled out by the lock claw 3A and the stopper wall IE. The user slides the battery cover 2 into the slide groove I.
The battery cover 2 is reliably attached to the housing 1 by simply pushing it along the direction A.

Next, when the drive unit 3 is pushed up in the direction of arrow B, the tip of the lock claw 3A comes off the stopper wall IE.

The battery cover 2 is pushed back by a push-out spring 4 to ensure that the battery cover 2 is in a removed state. Here, the battery cover 2 may be pulled out using the gap between the housing 1 and the battery cover 2 or the hook 2B.

FIG. 3 shows another embodiment of the present invention, where lO is a housing.

10E is a stopper wall, 20 is a battery cover, 20C is an extrusion spring holder, 20D is a recess, 20E is a stopper wall, 3G is a lid stopper moving part, 30A is a lock claw, 30B, 30C
is a boss, 30D is a spring, and 40 is a battery cover extrusion spring.

Next, the operation of the embodiment shown in FIG. 3 will be explained.

When the battery cover 20 is pushed in the direction of arrow C, the lock claw 30A of the battery cover 20 is pushed down, and when it comes to the recess 20D, the lock claw 30A is pushed up by the spring 30D, and 1! Pond cover 2
Prevents it from going out of 0.

Next, when removing the battery cover 20, when the drive unit 30 is pulled down in the direction of the arrow, the lock claw 30A comes off the stopper wall 20E of the battery cover 20, the push spring 40 pushes the push spring holder 20G, and the battery Push out the lid 20 in the opposite direction of arrow C to make it easier to remove the battery lid 20. here.

All you have to do is pinch the battery cover 20 and pull it out.

As described above, the battery covers 2 and 20 are inserted into the slide groove IA (first
The battery cover 2.20 can be securely held by inserting it into the battery compartment (see figure) and pushing it in the direction of the arrow, and the battery cover 2.20 can be easily unlocked by pushing up or down the drive unit 3°30. It was made so that it could be done.

(Effects of the Invention) As is clear from the above examples, the present invention has the following effects.

(1) When installing the battery cover of the individual call receiver, align the battery cover with the slide groove of the housing, insert it, and push it in fully to ensure that the stopper at the other end of the battery cover is firmly attached to the housing. locked.

(2) To release the lock, simply pushing up or down the drive unit pushes the battery cover back to a state where it can be removed from the housing, making it easy to remove the battery cover.

(3) Furthermore, when the battery cover is pushed in, it is possible to know that the lock has been reliably performed by the popping sound that is emitted when the lock pawl passes over the stopper wall.
