Abstract

PURPOSE:To facilitate the locking operation and enable a cell to be held securely, by providing a stopper which is unlocked as a cover is moved and is locked automatically as the cover is set completely. CONSTITUTION:With a cover 6 opened, a spring acting resilient part 14 is pushed upward by the resilient force of an arm 15 and inclination of a tapered slot 12, to fit a projection 15a into a recess 13. When the cover 6 is moved to the left, an enqoging piece 21 of a stopper 5 makes contact with a tapered rib 18 to generate a force component directed downward due to a slope 18a, thereby pressing the stopper 5 downward. Consequently in the spring acying resilient part 14, fitting the of projection 15a of the arm 15 is released and the stopper 5 moves downward. When the engaging piece 21 goes beyond the slope 18 of the tapered rib 18, as the force which presses the stopper 5 downward dissapears, the stopper 5 moves upward again to fit the projection 15a into the recess 13. Under this condition, the engaging piece 21 enters a stopper holding part 20 to keep the cover 6 locked to a body casing 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a battery storage device for preventing a battery used as a built-in power source of an electronic device from falling out.

Conventional technology FIG. 4 shows the external appearance of a battery storage device for an electronic device such as a general pager, in which a battery storage section 2 is provided by cutting out a part of the casing l, and a battery 4 is held by a holder 3. , a cover 6 having a stopper 5 is slid into the battery storage part 2 as shown by the arrow, and the stopper 5 is operated to prevent the battery 4 from falling out. As shown in FIG. 5, a part of the stopper conventionally has a retaining piece 7 that engages with an engaging portion 8 formed by a hole or the like provided at one end of the battery storage section 2 of the housing section 1 by sliding the stopper 5. However, it was designed to act as a stopper.

Problems to be Solved by the Invention However, in the configuration of the conventional example described above, the falling-off prevention effect depends on the degree of friction between the engaging piece 7 and the engaging portion 8 of the stopper 5. This has the disadvantage that it may become easier or, conversely, may become less slippery. In addition, the stopper 5 must be operated each time the cover 6 is attached or detached, which is cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a battery storage device that eliminates the drawbacks of the conventional example, is convenient to operate, and can securely hold batteries.

Means for Solving the Problems In order to achieve the above object, the present invention has a battery cover provided in a main body casing of an electronic device, in which one end of the battery cover comes into contact with the side wall of the battery compartment, and the cover is unlocked by inserting the cover. state,
The battery cover is configured to include a stopper that automatically returns to the locked state and engages with the battery cover at the end of installation.

Function: Since the present invention is constructed as described above, when the battery cover is attached, it is automatically locked, and the built-in battery is reliably held inside, thereby achieving the effect of preventing the battery from falling out.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. In these figures, the same symbols as in FIGS. 4 and 5 represent the same names. 10 is a fitting part provided on the side wall 1a of the (wooden) housing part 1 and a stopper 5
The groove 11 of the guide is fitted into the groove 11 and serves as a guide that moves up and down in FIG. Reference numeral 12 denotes a tapered groove that extends upward and is provided inside the fitting portion 10, and has a recess 13 at the top. Reference numeral 14 denotes a spring elastic portion inserted into the tapered groove 12, and has an arm 15 consisting of a pair of inverted V-shaped elastic pieces, and a semicircular protrusion 15a is provided at the tip of the arm 15. Reference numeral 16 indicates a slide groove that slides into the cover 6 and the guide 17 provided on the side wall 1a of the battery storage section 2 of the wooden housing section 1, and 18 indicates a first slide groove.
In the figure, a tapered rib provided inside the end 19 of the cover 6,
Reference numeral 20 denotes a stopper support portion consisting of a recess provided below the end portion 19. 21 is a retaining piece provided at the tip of the stopper 5. Note that the spring elastic portion 14, the tapered groove 12, etc. constitute upward biasing means.

Next, the operation of the above configuration will be explained. When the cover 6 is removed, the spring elastic part 14 is pushed upward by the elasticity of the arm 15 and the inclination of the tapered groove 12, and the protrusion 15a is pushed up into the recess 13.
is fitted. @1 When the cover 6 is moved to the left in the figure as indicated by the arrow in the figure, the engagement piece 21 of the stopper 5 hits the tapered rib 18, and its slope 18a generates a downward force in the figure, causing the stopper 5 to move. Try to push it down. Therefore, the spring elastic part 14 disengages the arm 15 and the projection 15a, and the stopper 5 moves downward. Next, the retaining piece 21
When it crosses the slope 18a of the tapered rib 18, the force pushing down the stopper 5 is lost, so the stopper 5 rises again, and the protrusion 16 and the recess 13 fit together. The cover 6 is held in a locked state by the wooden housing part 1. To remove the cover 6, press the stopper 5 with your finger, etc.
By pushing down, the engagement between the stopper support portion 20 and the engagement piece 21 is disengaged, so that the cover 6 can be easily moved to the right in FIG. 3.

That is, in the above embodiment, the cover 6 is automatically locked by simply moving the cover 6 to the locked state. Therefore, the operation is easy and there is no possibility of forgetting to lock the lock.

Effects of the Invention As explained above with reference to the embodiments, according to the present invention, when covering the battery storage section provided in the main body casing of an electronic device with a cover, the cover is released from the locked state as the cover moves, and the cover is completely removed. Since a stopper is provided that automatically locks when the battery cover is attached, there is no need to perform a locking operation when attaching the battery cover, and the lock does not depend on subtle friction from engagement pieces, etc., resulting in improved dimensional accuracy. It has the advantage of being rough and therefore good for protection.
