Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a battery storage device, and more particularly, to a battery storage device in which the power source battery can be replaced, such as a power source battery storage chamber for a camera or the like.

(Prior Art) As is well known, this type of battery storage device does not take up sufficient space due to its structure, making it extremely inconvenient.

Prior to explaining the present invention, an example of a conventional battery storage device of this type will be explained based on the drawings.

In FIG. 1, A and B show an example of a conventional battery storage device of this kind, in which a battery storage chamber lid 1 is shown.
is a horizontally elongated plate-shaped object that fits slidably in the longitudinal direction into a recess 4 in which an opening surface 4a of the battery storage chamber 3 is formed, which opens in the bottom wall 2 of the camera. It is arranged so as to cover the opening surface 4a of No. 3. A hinge portion 1a consisting of a vertical groove is formed near one end (the right end in the figure) of this battery storage chamber lid 1, and an end 1a to the right of the hinge portion 1a is formed.
b is formed to be thin, and this end portion 1b is adapted to fit freely in and out of a groove 2a parallel to the bottom surface, which is extended and bored along the top and bottom of the inner surface of the recess 4 of the bottom wall 2. . An elastic coil spring 5 is interposed between the right end surface of the lid 1 and the inner wall surface of the groove 2a, and the lid 1 is connected to the opening surface 4a of the battery storage chamber 3 of the bottom wall 2. Along the left side (in Figure 2)
It has a habit of moving to close the opening surface 4a. Furthermore, when the lid 1 is closed, that is, in the state shown in FIG.
When c comes into contact with the left inner surface 4b of the recess 4, its movement is restrained. Furthermore, when the lid 1 is closed, the locked portion 1d, which is formed in a stepped manner on the front end surface 1c of the lid 1, is moved from the longitudinal groove bored on the left inner surface of the recessed portion 4. The lid 1 is fitted into the locking portion 2c, and the lid 1 is locked in the closed state. In addition, a vertically elongated finger rest recess 6 is provided approximately at the center of the surface of the lid 1.
is provided. From the state shown in Figure 1,
When a finger is placed on the finger rest recess 6 and the lid 1 is pushed in the direction of arrow A against the elasticity of the coil spring 5,
The engagement between the locked portion 1d and the locking portion 2c of the camera bottom wall 2 is released. Next, when the recess 6 is pulled out in the direction of arrow B, that is, outward, the lid 1 is rotated counterclockwise about the hinge 1a and opened as shown in FIG. 1B. To close the lid 1 from this open state, place your finger on the recess 6 and push the lid 1 in the direction of arrow A (see Figure 1 A) while rotating it clockwise. When the latched portion 1d is pushed into the recess 4, the coiled spring 5
Due to its elasticity, the lid 1 fits into the locking portion 2c of the bottom wall 2, so that the lid 1 is locked in the closed state.

By the way, when opening and closing such a battery compartment lid, place your finger on the finger rest recess 6 of the lid 1,
It is not easy to pull out the lid 1 in the direction of arrow B (see FIG. 1A). However, it is extremely difficult to design a structure for automatically pulling out this device due to space constraints. On the other hand, the force that pushes the lid 1 from inside is
When a battery is stored in the battery storage chamber 3, a contact spring (not shown) is provided to ensure complete contact between the battery and the electrical contacts in the battery storage chamber 3. The lid 1 will be pushed outward, but the force of this spring is extremely small, so
It is of no practical use, and its resiliency does not act on the lid when the battery is not stored.

FIGS. 2A and 2B show other examples of conventional battery storage devices of this type. The battery storage chamber lid 11 in this example is adapted to be removably fitted into an opening 14 of a battery storage chamber 13 that opens on one side 12 of the camera so as to cover the opening 14. As shown in FIG. 2B, the lid 11 is in the shape of a vertically long rectangular plate, and its outer surface has a low rectangular roof shape, and one side thereof has a vertical ridge. An engaging portion 11a is formed to fit into a vertical groove 14a bored in the inner surface of one side of the opening 14. Further, on the other side of the inner surface of the lid 11, a locking member 15 made of a vertically long elastic plate is fixed at its upper end with a mounting screw 16. A wedge-shaped locked portion 17 that protrudes outward at right angles is integrally formed at the lower end of the locking member 15, and is connected to the outside of the lid from the back side of the locked portion 17. A pushing portion 18 made of a prismatic column that protrudes toward the side surface is integrally provided. and,
A notch 19 is formed in a portion of the battery storage chamber cover 11 that faces the pushing part 18, and is large enough to allow the pushing part 18 to fit therein with a margin. On the other hand, on the inner wall of the opening 14 of the camera body, which faces the locked portion 17 of the locking member 15, there is a locking portion 20 formed of a square hole into which the locked portion 17 is fitted and locked. It is provided.

The lid 11 is attached to the opening 14 of the battery storage chamber 13 configured as described above in the following manner. That is, after the battery 21 is stored in the battery storage chamber 13, the engaging portion 11a of the lid 11 is fitted into the vertical groove 14a formed in the opening 14.
Next, the lid 11 is rotated clockwise about the engaging portion 11a fitted into the vertical groove 14a, and is pushed into the opening 14. Then, the locked portion 17 of the locking member 15 attached to the lid 11
is in sliding contact with the opening side edge of the locking part 20 provided in the opening 14, and is pushed in the direction of arrow C against the elasticity of the locking member 15. When facing the locking part 20, the stored elasticity causes it to fit into the locking part 20 and to be locked in the state shown in FIG. 2A.

Moreover, in this way, the opening 14 of the battery storage chamber 13
When removing the lid 11 that is locked and attached to the opening 14, the pushing part 18 of the locking member 15 is pressed.
is pushed in the direction of arrow C against its elasticity. Then, the locked part 17 integrated with the pushing part 18 also moves as shown by the arrow C.
The lock is released by moving in the direction and coming out of the locking part 20, so pinch the pushing part 18 with your fingers and pull it outward, and then operate it in the opposite direction to that used when installing. , the lid 11 can be easily removed from the opening 14.

By the way, even when opening and closing the battery compartment lid 11, since the lid 11 is small,
The pushing portion 18 is also extremely small, making it extremely troublesome and inconvenient to pull it out by pinching it with your fingers.

(Problems to be Solved by the Invention) As described above, it is difficult to open the lid of the conventional battery storage device by hand, and it has been desired to eliminate this drawback.

In view of the above points, an object of the present invention is to skillfully form a release member for releasing the lock of the locking member of the lid, and to automatically lock the lid by the unlocking operation of the release member. It is an object of the present invention to provide an extremely convenient battery storage device which is operable in the opening direction and which completely eliminates the drawbacks of conventional opening/closing devices of this type.

(Means and effects for solving the problem) The present invention has a battery storage chamber and a battery storage chamber lid that opens and closes the battery storage chamber, and the battery storage chamber has a locking portion abutted inside. and the lid includes a locking hook portion and a locking release member, the locking hook portion being biased to engage the locking portion and hold the lid in the closed position. The locking release member is movably held by the lid, and when moved in one direction, displaces the locking hook portion in a direction to release the engagement with the locking portion, and is pressed. A moving part is integrally provided, and the pushing part contacts the abutted part when the lid is moved in the one direction with the lid closed, and the pushing part and the covered part come into contact with each other. At least one of the contact surfaces of the contact section is an inclined surface, and the inclined surface applies a component force in the direction of opening the lid to the pushing section when the pushing section and the abutted section come into contact with each other. The gist of the present invention is a battery storage device characterized in that it generates electricity.

According to the present invention, the lid automatically moves in the opening direction by the movement of the unlocking member in the releasing direction, making it extremely easy to open and close the lid. This provides an extremely practical battery storage device that has never been available before.

(Example) Hereinafter, the present invention will be explained based on the illustrated example.

Near the lower end of the locking member 33, the locking member 33 protrudes inward perpendicularly to the surface of the lid 31, and extends from its tip at right angles parallel to the inner surface of the lid 31 toward the outer edge of the lid 31. A hook portion 36 having a protruding claw 36a is integrally formed. On the other hand, on the inner surface of the side wall of the storage case 32a facing the hook portion 36, there is a locking hole 38 into which the claw 36a of the hook portion 36 is fitted.
is provided. A locking release member 34 for releasing the locking of the locking member 33 is provided at the lower part of the battery storage chamber cover 31 below the locking member 33.
is arranged so as to be able to freely slide in the vertical direction. As shown in FIG. 4, this unlocking member 34 has a flat rectangular shape made by molding a synthetic resin material, etc., and has a longitudinal direction in the center of its upper end surface. A slotted groove 34e is bored, and a pushing part 34b that protrudes upward and faces the inclined surface 37a of the pushed part 37 of the locking member 33 is provided at the left end (in the figure) of the inner wall. It is formed. Further, from the middle to the lower end of the inner surface of the release member, an inclined convex portion 34b having a protruding inclined surface 34a is formed. This inclined convex portion 34b serves as a pushing portion for a fixed side inclined recessed portion 35, which will be described later.
And on the outer surface on the opposite side, the above-mentioned inclined surface 34a
A finger rest recess 34 having an inclined surface substantially parallel to the

By pushing upward in the direction of arrow D, the member 34 is moved in the same direction. Then, the upper end surface of the pushing part 34b of the member 34 comes into contact with the inclined surface 37a of the pushed part 37 at the lower end of the locking member 33, and the pushed part 37 is moved by the elastic force of the locking member 33. The hook portion 36 is pushed in the direction of arrow E against the
When the hook portion 36 moves in the same direction, the claw 36a disengages from the locking hole 38 of the storage case 32a, so that the lock is released. Next, when the release member 34 is further pushed upward, the slope 34a of the release member 34 comes into contact with the slope 35a of the slope recess 35 of the storage case 32a, and slides on the slope 35a to release the same. Release member 34
moves in the direction in which the lid 31 opens. Therefore, simply by pushing the release member 34 upward, the locking of the lid 31 is released and the lid 31 is automatically rotated in the opening direction, so that the lid can be locked with a single touch. Release and opening operations are performed. Therefore, the drawbacks of conventional battery storage devices of this type are completely eliminated.

(Effects of the invention) As explained above, according to the invention, the invention has the following advantages, which were considered indispensable for conventional hinge-opening lids of this type:
There is no need for any opening/closing springs such as coil springs wrapped around the support shaft, and there is no need for troublesome operations such as pulling up using fingernails, as the device can simply be pushed with a finger. Therefore, it is possible to provide an extremely convenient battery storage device that is extremely easy to operate. Although the above embodiment is a case of a rotary opening/closing lid, it goes without saying that the present invention can be similarly applied to a removable opening/closing lid shown in FIG. 1 above.
