Abstract

PURPOSE:To eliminate the necessity of doing troublesome operations by providing a battery case with a battery lid lock member, which is to lock a battery lid in linkage with a battery detection member, and a lock release member manually controllable from outside. CONSTITUTION:When inserted in a battery, a battery detectin rod 13 is pressed leftward, and accordingly a battery detection lever 7 rotates counterclockwise to make a battery lid retaining cathcer lock plate 8 slide rightward. In this way, an indicator 8c moves to a point facing a window 11c to indicate that the battery is inserted. At the same time, a portrusion 8f of the lock plate 8 and a protrusion 4d engage with each other, and therefore a battery lid release knob 6 is locked so that it can not be pressed downward. To release it, press the battery lid release knob 6 downward while pushing in a lock release knob 10 against the spring force of the battery lid retaining cathcer lock plate 8 itself. Then a protrusion 4a of a battery lid retaining catcher 4 and the protrusion on a camera side are disengaged and the battery lid is opened.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery case, and more particularly to a locking mechanism for automatically locking a battery cover of a battery case depending on whether or not a battery is present in the battery case.

Some conventional battery cases were equipped with a locking mechanism and some were not, but in both cases, the presence or absence of a battery in the battery case (1) has nothing to do with the locking mechanism in the front. Met.

Therefore, with the former type of battery case, when there is a battery in the battery case, it is convenient because the battery does not come out, but there is no structure inside the battery case, so when you insert a new battery into the battery case, you have to put the battery in the battery case. The locking mechanism of the lid had to be removed, which was very cumbersome to operate. In addition, the latter battery case does not have a locking mechanism, so you can easily insert the battery into the battery case, but because it does not have a locking mechanism, the battery may pop out when used in portable items such as cameras, transceivers, and radios. The drawback was that there was fear.

In view of these drawbacks, the battery cover of the battery case is provided with a locking mechanism that can be locked arbitrarily, and the lock mechanism W is disabled when the battery is not inserted into the battery case, and the lock mechanism W is disabled when the battery is inserted into the battery case.
There was a battery case configured to make # work, but
There was a drawback that it was extremely troublesome to set the locking machine m+t- each time.

The battery 12 inserted into the battery case pushes the stain pond detection rod 13 to the left in FIG. Slide it to the right. As a result, the display section 8C moves to a position corresponding to the window 110 and displays that the battery is inserted.

At the same time, the protrusion 8f and the protrusion 4d of the lock plate 8 engage, so the battery cover opening knob 6 is locked so that it cannot be pushed downward as shown in FIG. 4, and the battery cover does not open. The battery will not pop out.

Next, using Figures 6 and 7, we will explain the operation when releasing the locked state to release the battery cover after inserting the battery.iii! I will clarify. To release the locked state (7), push the lock release knob 10 upward as shown in FIG. 7 against the spring force of the battery cover retaining claw lock plate 8. p, m The engagement between the upwardly bent protrusion 8C and the protrusion 4d shown in FIG. 7 is released, and the battery cover locking claw 4 becomes able to slide downward as shown in FIG. At this point, if you push down the battery cover release knob 6 while pressing the lock release knob 10t, the projection 4a of the battery cover locking claw 4 will be disengaged from the projection 3 on the camera side, and the battery will be released. state.

In the first embodiment of the present invention, the lock plate 8 is made elastic so that it can be unlocked, but the lock plate 8 is not made elastic and the battery is constructed so that it pops out when the battery cover is opened. A second embodiment of the invention will be described using FIGS. 8 to 10. 8 and 9 are sectional views of essential parts of the second embodiment of the present invention, and FIG. 10 is an enlarged view of the vicinity of the torsion spring 26. In FIGS. 8 and 9, 20 is a lock plate provided with a knob 21 (8) to be described later, and 21 is a lock plate that unlocks the battery cover by sliding the knob to the left.

22 is a first battery detection lever, 25 is a second battery detection lever that is supported by the first battery detection lever 22 and a shaft 25, and 24 is a first battery detection lever as shown in FIG. A stopper 22 is provided by bending a part of the second battery detection lever 23 to prevent it from rotating counterclockwise about the shaft 25.

26 is a torsion bar that biases the first battery detection lever 22 and the second battery detection lever 23 so that they form a "<"shape; 27 is pivotally supported by the tig2o battery detection lever and a shaft 28; It is a battery detection stick. Portions not shown in FIGS. 8 and 9 have the same configuration as the first embodiment, and therefore will not be illustrated or described.

Before the battery 12 is inserted into the battery case, the lock plate 20 is biased to the left by the lock plate spring 9 as in the first embodiment, and the lock plate and the battery cover locking claw 4 are not engaged. The battery cover release knob 6 shown in the embodiment of @1(9) can be lowered to open the battery cover 2. As shown in the M% diagram, when the battery 12 is placed in an artificial state and the battery cover 2 is closed, the battery detection rod 27 is biased to the left, and the second battery detection lever 25 is biased counterclockwise. At the same time, the battery detection lever 22 of the power supply 1 is also biased counterclockwise by the force of the torsion spring 26, and the lock plate 20 is biased rightward. Therefore, the lock plate 20 and the battery cover locking pawl 4 are engaged, and the battery cover release knob 6 is locked without being able to be lowered downward. Further, depending on the position of the knob 21, the user can determine whether the battery is present or not.

In order to release the lock and open the battery cover 2, move the knob 21 to the left against the force of the torsion spring 26 as shown in FIG. unlock. As a result, the battery cover release knob 6 can be lowered downward, and the stain electric picture 2 can be opened.

At the same time, lock plate 20 #! 1 battery detection lever 22
is biased clockwise, resulting in torsion (10). The battery detection lever 22 of the multimeter 2 is also biased clockwise by the force of the spring 26, so the battery detection rod 2-7 is biased rightward. The battery 12 is also biased to the right. Therefore, when the battery cover 2 is opened, the battery 12 pops out.

In addition to the effects of the first embodiment, this embodiment has the advantage that when the four locks on the battery cover are released and the battery cover is opened, the battery automatically pops out.

In the embodiments of the present invention, a battery detection rod is used as a battery detection member that responds to battery loading, but it does not necessarily have to be rod-shaped. In the embodiment of the present invention, a battery lid locking spring plate 8 is used as a battery lid locking member that locks the battery lid in response to the battery detection member. In addition, the unlocking member manually operable from the outside for unlocking the battery lid by the battery lid locking member is the unlocking knob 10 in the first embodiment, and the knob 21 in the second embodiment.

As described above, according to the present invention, there is provided a battery cover, a battery detection member that responds to loading of the battery (11), a battery cover locking member that locks the battery cover in response to the battery detection member, and a battery cover locking member. The battery case is equipped with a lock release member that can be manually operated from the outside to unlock the battery cover, so the battery cover will not lock when there are no batteries in the battery case, but will automatically lock when a battery is inserted into the battery case. The battery cover can be locked automatically, and stains do not come out due to the user's carelessness and forgetting to lock it, and the locking mechanism always functions like a conventional battery case. If the battery is not in the battery case and you put the battery in the battery case, you do not have to remove the locking mechanism each time, or manually lock the battery each time you insert the battery.
There is no need for troublesome operations to make tto function, and the effect is great.

Furthermore, according to the present invention, it is possible to indicate whether or not there is a lumi pond by the member that responds to the battery detection member, and the user has to open the battery case each time to check whether or not there is a battery in the battery case. It can be confirmed without opening (12), and the effect is even greater.
