[Prior art]

 In portable electric devices such as radios and tape recorders that consume relatively little power, portable batteries or rechargeable batteries are usually available. Therefore, in these electric devices, a storage chamber for storing a battery or a battery storage case in which the battery is stored is formed.

FIG. 5 shows a conventional battery lid opening / closing mechanism. Note that FIG. 5 is a diagram showing an example in which the battery storage case is stored in the storage chamber.

In FIG. 1, reference numeral 1 denotes a storage chamber formed in an electric device, and an insertion port P into which a battery storage case T is inserted is formed at one end of the storage chamber 1. The battery housing case T is provided with an electrode portion (not shown) that supplies a current to an electric device (not shown).

Further, as shown in FIG. 5A, the storage chamber 1 is formed with an escape portion 1 a for a battery lid 2 which will be described later. As shown in FIG. 5B, the escape portion 1 a is for allowing the battery lid 2 to escape above the storage chamber 1 when the battery storage case T is stored in the storage chamber 1.

Reference numeral 2 denotes a battery lid, and the battery lid 2 is rotatably arranged by a shaft 3 above the insertion port P side of the storage chamber 1. The shaft 3 is arranged on the side of the insertion port P of the escape portion 1a of the storage chamber 1. A spring 4 is attached to the shaft 3 and the battery cover 2 as shown in FIG. 5A. The spring 4 always biases the battery lid 2 in the counterclockwise direction to bring it into a closed state.

Reference numeral 5 denotes a spring, and the spring 5 is arranged on a side surface (a surface facing the insertion port P) on the other end side of the storage chamber 1.

A locking means (not shown) is arranged on the lower surface of the storage chamber 1. Then, at the same time when the battery storage case T is inserted into the storage chamber 1, the battery storage case T and the locking means are locked to hold the battery storage case T in the storage chamber 1. Further, a releasing member (not shown) is arranged in the locking means, and the locking of the battery storage case T and the locking means is released by operating the releasing member.

In the example of FIG. 5, in order to store the battery storage case T in the storage chamber 1, the battery storage case T is inserted so as to face the insertion port P as shown by the chain double-dashed line in FIG. 5A. . Then, the battery lid 2 and the battery storage case T come into contact with each other, and the battery lid 2 tilts clockwise against the biasing force of the spring 4. Then, when the battery storage case T is further inserted, the battery storage case T and the locking means (not shown) are locked. In the stored state, as shown in FIG. 5B, the battery lid 2 escapes to the escape portion 1a and is held in a substantially horizontal state with the battery storage case T, and the spring 5 is compressed by the battery storage case T. Is held.

To take out the battery storage case T from the storage chamber 1, the unlocking member of the locking means (not shown) is operated to unlock the battery storage case T and the locking means. Then, the battery storage case T projects from the insertion port P by the urging force of the spring 5, so that the battery storage case T can be taken out from the storage chamber 1.

When the battery storage case T is taken out of the storage chamber 1, the battery lid 2 is rotated counterclockwise by the urging force of the spring 4 to be in a closed state. That is, the battery lid 2 is held in the vertical state shown in FIG. 5A by abutting the base portion of the battery lid 2 and the side surface of the escape portion 1a of the storage chamber 1 on the insertion port P side.

[Problems to be solved by the device]

 In the example of FIG. 5, the battery lid 2 is held in the vertical state (the state shown in FIG. 5A) by the biasing force of the spring 4. Therefore, the battery lid 2 can be easily opened / closed by fingers or the like in addition to the battery storage case T, so that dust or the like may enter the storage chamber 1. If the battery storage case T is stored in a state where dust is contained in the storage chamber 1, the battery storage case T may not be stored in the storage chamber 1. Similarly, a nonstandard battery storage case may be easily stored.

Therefore, the present invention prevents the battery lid and the like from being easily opened and closed by a finger or the like except when the battery or the like is stored.

[0014]

[Means for Solving the Problems]

In addition to forming a stopper, an engaging portion that engages with a battery or the like is formed on the insertion port side of the storage chamber of the locking portion so that when the battery or the like is stored in the storage chamber, the battery and the engaging portion are It is characterized in that the engagement between the engaging portion and the battery lid or the like is released by engaging the engaging portion to open the battery lid or the like.

[0015]

[Action]

 When, for example, the battery storage case T is stored in the storage chamber 1, the battery storage case T and the engaging portion 8 are engaged with each other, and the locking between the locking portion 7 and the battery lid 2, for example, is released. Then, when the battery storage case T is further inserted, the battery lid 2 is rotated to be in an open state, and the battery storage case T is stored in the storage chamber 1. In the state where the battery storage case T is not stored in the storage chamber 1, the battery cover 2 and the locking portion 7 are locked, so that the battery cover 2 does not rotate even if the battery cover 2 is pushed with a finger or the like. Therefore, it is possible to prevent the battery lid 2 from being opened, the dust and the like from entering the storage chamber 1, and the battery storage case T from being unable to be stored. Further, when a nonstandard battery storage case or the like is stored in the storage chamber 1, it is not easy to release the locking between the locking portion 7 and the battery lid 2, and a nonstandard battery storage case or the like is stored in the storage chamber 1. You can confirm that it is stored in.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3, parts corresponding to those in FIG. 5 are designated by the same reference numerals, and detailed description thereof will be omitted. 1 is a front view of the storage chamber 1, and FIG. 2 is a sectional view taken along line I-I of FIG.

In FIG. 2, 6 is a locking piece, and this locking piece 6 is formed integrally with the bottom plate of the storage chamber 1. As shown in FIG. 2, the locking piece 6 has a locking portion 7 formed at its tip. A recess 7a is formed in the locking portion 7 at a portion corresponding to the tip of the battery lid 2 in the closed state. Then, the locking portion 7 and the battery lid 2 are engaged with each other to hold the battery lid 2 in the closed state. The locking portions 7 (locking pieces 6) are formed in a pair as shown in FIG.

As shown in FIG. 2, a tapered engagement portion 8 is formed at the tip of the locking portion 7. The engagement portion 8 is formed so as to engage with the battery storage case T when the battery storage case T is stored in the storage chamber 1. When the engaging portion 8 and the battery storage case T are engaged with each other, the locking piece 6 tilts clockwise.

The present example is configured as described above, and the other points are the same as the example of FIG. The locking portion 7 is tapered on the spring 5 side. This is for facilitating the battery storage case T to pop out of the storage chamber 1 when the lock between the battery storage case T and the locking means (not shown) is released.

To store the battery storage case T in the storage chamber 1, the battery storage case T is inserted so as to face the insertion port P of the storage chamber 1 as shown by the chain double-dashed line in FIG. When the battery storage case T and the engaging portion 8 come into contact with each other and the locking piece 6 tilts clockwise, the engagement between the battery lid 2 and the locking portion 7 is released, as shown in FIG. 3A.

Further, when the battery housing case T is further inserted, as shown by the chain double-dashed line in FIG. 3A, the battery lid 2 is disengaged from the shaft in a state where the engagement between the battery lid 2 and the locking portion 7 is released.

In order to take out the battery storage case T from the storage chamber 1, the lock between the battery storage case T and the locking means is released by operating the release member of the locking means (not shown). Then, the battery storage case T and the locking portion 7 come into contact with each other, but since the biasing force of the spring 5 is set to be stronger than the elastic force of the locking piece 6, as shown in FIG. 3A, The locking piece 6 tilts clockwise. In other words, the battery storage case T is ejected from the insertion port P by the biasing force of the spring 5, so that the battery storage case T can be taken out from the storage chamber 1.

When the battery housing case T is taken out, the battery lid 2 moves from the state shown in FIG. 3B to the state shown by the solid line through the chain double-dashed line in FIG. 3A. That is, the battery lid 2 is rotated counterclockwise to be in the closed state.

When the battery storage case T is taken out, the locking piece 6 is urged in the counterclockwise direction by its elastic force and returns to the state shown in FIG. At the time of this return, the battery lid 2 is in the closed state, that is, the vertical state shown in FIG. 2, so that the battery lid 2 and the locking portion 7 are engaged and the battery lid 2 is held in the closed state.

Even if the battery lid 2 is pushed with a finger or the like when the battery storage case T is not stored in the storage chamber 1, the battery cover 2 is locked by the locking portion 7, so that the battery cover 2 is simple. Never open.

Further, for example, when a battery storage case smaller than the standard is stored in the storage chamber 1, the battery storage case does not push down the engaging portion 8 reliably, so that the battery cover 2 and the locking portion 7 are It is not easy to release the lock. Therefore, it can be confirmed that a battery storage case smaller than the standard is stored in the storage chamber 1.

According to this example, since the battery lid 2 and the locking portion 7 are locked when the battery storage case T is not stored in the storage chamber 1, even if the battery cover 2 is pressed with a finger or the like. , It does not open easily. Therefore, according to this example, it is possible to prevent dust and the like from entering the storage chamber 1 and preventing the battery storage case T from being stored.

FIG. 4 shows another embodiment. In this example, the insertion port P and the battery storage case T are flush with each other when the battery storage case T is stored in the storage chamber 1. In this case, the battery storage case T is formed with an engagement portion T1 that engages with the locking portion 7 at a portion corresponding to the locking portion 7 in a state where the battery storage case T is stored in the storage chamber 1. . Other configurations are similar to those of the example of FIG.

According to the example of FIG. 4, since the insertion port P and the battery storage case T are flush with each other when the battery storage case T is stored in the storage chamber 1, the appearance around the insertion port P is good. You can Other functions and effects are similar to those of the example of FIG.

In the above embodiment, the example in which the engaging portion 8 is tapered is shown, but the portion corresponding to the engaging portion 8 of the battery storage case T may be formed in a tapered shape. Further, in the above-described embodiment, an example in which the one housed in the storage chamber 1 is the battery storage case T is shown, but the one housed in the storage chamber is not limited to this. Further, the door that opens and closes the storage chamber 1 is not limited to the battery lid or the like.
