Description

[Detailed description of the invention] Industrial application field The present invention relates to a locking device for a battery lid, and in particular, it covers a battery compartment formed in a cabinet with a battery lid, and uses the battery lid as a locking means. The present invention relates to a locking device for a battery lid which is locked by the locking method.

〓Background technology and its problems〓 Electronic devices that are generally powered by batteries, such as portable radio receivers, have a battery compartment formed in a part of their cabinet. A battery is stored in the battery compartment to drive the radio receiver. If the opening constituting the battery storage section is exposed as it is, not only will the appearance be damaged, but there is also a risk that the battery may fall out. Therefore, a battery cover is attached to such a battery compartment and is locked by a locking means.

A conventional battery cover locking mechanism uses a battery cover 3 having an L-shaped cross section so as to cover an opening 2 formed in a cabinet 1, as shown in FIG. 4, for example. The claw 5 formed at the tip of the battery cover 3 is moved by the rail 4 formed along the edge of the battery cover 3 into the protrusion 6.
It was designed to lock by engaging with the lock.

A battery lid 3 that covers such a conventional battery compartment 2
According to this lock structure, the battery housing section 2 must be formed in a corner portion of the cabinet 1, which creates design constraints. Furthermore, according to such a conventional battery cover 3 locking device, the battery cover 3 must be moved to the left in FIG. 4 with a large stroke, which requires a large space for locking. There are drawbacks.
Further, when taking out the battery stored in such a battery storage section 2, a taking out means such as a taking out belt is required, which makes handling difficult.

FIG. 5 shows another conventional locking device for a battery lid 3. This battery lid 3 is provided with a U-shaped deformed portion 7 at one end thereof, and a claw 5 is formed in this deformed portion 7. It is becoming more and more common. Further, an L-shaped locking portion 8 is formed at the other end of the battery cover 3. Therefore, with the locking portion 8 hooked onto the edge of the opening 2, the battery cover 3 is rotated as shown by the arrow in FIG. Then, the U-shaped deformable portion 7 is deformed, the claw 5 is engaged with the protrusion 6, and the battery cover 3 is locked.

In such a locking device for the battery cover 3,
Since the claw 5 is formed into a U-shaped deformed portion 7, the U-shaped deformed portion 7 is not effectively used as a dead space, and therefore the space in the battery storage portion 2 is reduced. It has the disadvantage of being large. Furthermore, even in such a conventional device, when removing the battery stored in the battery storage section 2, a pull-out means such as a pull-out belt is required, and this device has the same drawbacks as the device shown in FIG. was.

〓Purpose of the invention〓 The present invention was made in view of the above-mentioned problems, and provides a locking device for the battery cover that does not require a large dead space in the battery compartment and also allows easy removal of the battery. The purpose is to provide the following.

〓Summary of the invention〓 The present invention provides an apparatus in which a battery compartment formed in a cabinet is covered with a battery lid, and the battery lid is locked by a locking means. A vertical wall is integrally formed, a slit is provided in the wall, and an elastic piece is formed such that the distal end of the wall is the proximal end and the battery cover side is the free end. This device relates to a locking device for a battery lid, characterized in that the formed pawl is locked to a locking portion on the side of the battery compartment, thereby reducing the dead space required for locking. At the same time, by making effective use of the wall portion having elastic pieces to hold the battery, for example, the battery can be easily removed.

〓Example〓 The present invention will be described below with reference to an illustrated example.
FIG. 1 shows a radio receiver equipped with a battery cover locking device according to this embodiment.
It is equipped with The rear side of this cabinet, that is, the upper side in FIG. 1, is an opening, and a back cover 12 constituting the rear side cabinet is attached to close this opening.
A battery housing section 13 consisting of a recess is formed in this back cover 12. A battery lid 14 is attached to the battery storage portion 13, thereby closing the recess 13. The battery cover 14 is provided with a pair of vertical walls 15, and the battery pack 16 is held by these vertical walls 15. Note that the battery pack 16 is adapted to hold, for example, four dry batteries 17.

The battery cover 14 is integrally molded from synthetic resin, and a pair of vertical bolts 15 are connected to the battery cover 14 so as to extend vertically downward. A pair of slits 18 are formed in each of the pair of vertical walls 15, and these pair of slits 18 extend to the battery cover 14 side and intersect with each other.
is formed. Therefore, the base end of the elastic piece 19 is on the tip side of the vertical wall 15, and the free end is on the side of the battery cover 14 (see FIG. 2). A lock claw 20 is provided on the outer surface side of this elastic piece 19.
is beginning to form. This lock claw 2
0 is adapted to be engaged with the upper edge of an opening 21 formed in the wall constituting the battery storage section 13, thereby locking the battery compartment 13 (see Fig. 3). ).

Further, on the inner surfaces of the pair of vertical walls 15 formed on the battery lid 14, which are opposite to each other, there are protrusions 22.
These protrusions 22 are adapted to engage with grooves 23 formed on the outer surface of the battery pack 16. This allows the battery pack 16 to be held on the battery cover 14. A protrusion 24 is formed inside the groove 23 of the battery pack 16, and an intermediate member 25 is stretched across the battery pack 16.

Therefore, two dry batteries 17 are housed in each of the upper and lower parts of the battery pack 16 divided by the protrusion 24 and the intermediate member 25. The battery pack 16 is held by the pair of vertical walls 15 of the battery lid 14 via the protrusions 22 by the grooves 23. As a result, four dry batteries 17 are held on the lower surface of the battery cover 14, as shown in FIG.

Once the four dry batteries 17 are held in the battery cover 14 via the battery pack 16 in this way, the upper end of the elastic piece 19 formed on the pair of vertical walls 15 of the battery cover 14 so that it can be elastically deformed is pressed. Pick at the second
Elastically deform inward as shown in the figure. In this state, the battery cover 14 is gently moved downward so that the battery cover 14 covers the opening of the battery storage section 13. A pair of recesses 26 are formed in the battery storage portion 13 so that fingers can be easily inserted at this time. When you release your finger after this, the elastic piece 20 returns to its original state due to its own elastic restoring force.
As shown in FIG.
It will be engaged with the upper edge of the.

As described above, according to the locking device for the battery cover 14 according to the present embodiment, the locking is performed by the locking pawl 20, and this locking pawl 20 is integrally supported by the vertical wall 15 in a cantilever manner. Since the elastic piece 19 is formed with a
There is less space for elastic deformation. Therefore, from this, the dead space of the battery storage section 13 is reduced. Therefore, the area occupied by the battery storage portion 13 in the cabinet 12 is also reduced.

Furthermore, since the battery cover 14 holds the dry battery 17 through the pair of vertical walls 15 and the battery pack 16, replacing the battery 17 becomes very convenient. That is, when replacing the battery 17, the battery cover 14 can be removed by inserting a finger into the recess 26 around the battery storage section 13 of the cabinet 12 and deforming the upper end of the elastic piece 19. As a result, the dry battery 17 is taken out together with the battery cover 14 from the battery storage section 13 in a reverse operation to that shown in FIG. Therefore, there is no need to provide a take-out means such as a take-out belt, and the battery 17 can be easily taken out.

Although the present invention has been described above with reference to an illustrated embodiment,
The present invention is not limited to the above embodiments, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiment, a pair of vertical walls 15 are formed on the lower surface of the battery lid 14, but the pair of vertical walls 15 are not necessarily formed, and only one vertical wall 15 is formed. You can do it like this. Also, without using the battery pack 16, the dry battery 17 can be directly connected to the vertical wall 15.
The structure may be such that it holds the . Alternatively, a rechargeable battery having the same shape as the battery pack 16 may be used to drive the radio receiver.

〓Effect of the invention〓 As described above, the present invention integrally forms a wall that is almost perpendicular to the battery cover, and also provides a slit in this wall so that the tip side of the wall is the base end and the battery cover is connected to the battery cover. An elastic piece is formed so that the side thereof becomes a free end, and a claw formed on the elastic piece is engaged with a locking part on the battery storage section side to perform locking. Therefore, according to the present invention, it becomes possible to perform locking using the claws of the elastic pieces supported in a cantilever manner, and the space for locking can be reduced. Therefore, the dead space of the battery storage section is reduced, and the space inside the cabinet can be used effectively. Furthermore, the vertical wall section provided with the elastic piece can be used for other purposes, such as for holding batteries, thereby making it very easy to attach and detach the batteries.
