Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a charger that can charge rechargeable batteries of different lengths, and in particular to a charger that can charge batteries that are shorter than a single battery. Concerning vessels.

(B) Prior Art Conventionally, D, C, and D cells have been widely used, and there are chargers that can charge these batteries of different lengths and diameters. A single cell has a longer length and a larger diameter than a unit cell and a unit cell, and a single cell has the same length as a single cell but has a larger diameter. We previously proposed a charger in which a set of power supply contact pieces was provided on the opposite inner wall of the battery storage recess for storing such batteries, and the above-mentioned different types of batteries could be connected between the power supply contact pieces (Jikkosho). 56-9267). This is to adjust the difference in length between single cells and single cells by raising and lowering the length of the length adjuster.

However, with the spread of these batteries, single cells or cells, which are smaller than single batteries, are now being charged using dedicated chargers for these batteries. It is desirable to charge the battery using a charger. Moreover, when a regulator such as the one described above is provided for such a small battery, it is desirable that it be inconspicuous except when in use.

(c) Purpose of the invention The present invention has been devised in view of the above points, and aims to provide a charger that can not only charge a unit cell or a unit cell but also charge a battery smaller than a unit cell.

(d) Structure of the invention In order to achieve the above object, the charger according to the invention includes a battery storage recess provided with a recess for storing a single or single battery, and a power supply contact piece provided on the opposite inner wall of the recess, respectively.
A first member pivotably supported between a horizontal position located at the bottom of the recess and an upright position along the opposing inner wall.
An adjusting body is provided in the recess, and is pivotally supported so as to be swingable between a lying position in which the distal end is located astride the recess and a standing position in which the distal end is located outside the recess and the entire body fits within the side wall of the recess. A second adjustment body is provided in the recess, and a small battery shorter than a single battery can be connected between the power supply contacts via the first and second adjustment bodies.

(E) Embodiment An embodiment of the present invention will be explained below based on the drawings. FIG. 1 is a perspective view of the charger, and FIG. 2 is a side view with the main parts cut away. In these drawings, the charger case 1 is composed of a main case 2 and its bottom cover 3, and battery storage recesses 4, 4 are formed on the upper surface of the main case 2, and a space between the main case 2 and the bottom cover 3 is formed. Parts that require charging, such as step-down transformers, are housed in the compartment.

Each battery storage recess 4 has a length capable of storing two cells in a row, and has a curved surface 6 for receiving the cell 5, as shown in FIG. 3, which is a cross-sectional view of the recess 4. A recess 8 for housing the cell 7 is formed at the bottom of the surface. Cell 9 is supported on recess 8 .

On the opposing inner walls 10 and 11 of each battery storage recess 4,
Positive power supply contact piece 12 and negative power supply contact spring 1
3 and 14 are attached. The metal fitting 12 serves as a common positive terminal, the spring 13 serves as a negative terminal for single cells, and the spring 14 serves as a negative terminal for single cells, single cells, and batteries smaller than single cells. Double contact piece spring 13,
14 is attached to the lower surface of the recess 8 as shown in FIG.

Next, 15 is a first adjustment body, and the bottom 1 of the recess 8 is
6, the entire body is pivotably supported between a horizontal position in the recess 8 and an upright position in contact with the contact piece fitting 12. FIG. 4 is a partial perspective view of the first adjustment body 15 and the battery storage recess 4, and as shown in this drawing, the first
A shaft portion 18 is provided protrudingly on both sides of the resin body 17 of the adjustment body 15, and this shaft portion 18 is inserted into the hole between the lower end of the elastic piece 19 provided on both sides of the recess portion 8 and the bottom wall 20 of the recess portion 8. It can be attached by attaching it to 21. When the resin body 17 is erected as shown in FIG.
It has an eyelet fitting 22 that comes into contact with the eyelet fitting 22, and a terminal fitting 23 that is attached at a position opposite to the attachment position of the eyelet fitting, and a resistor 25 that connects the eyelet fitting 22 and the terminal fitting 23 in a space 24 in the resin body. It is stored.

Reference numeral 26 denotes a second adjustment body, and as is clear from FIG. 5, which shows a perspective view of this adjustment body and the recess 8, the recess 8
A recess 27 provided on one side has two positions: a lying position where the tip 28 of the adjusting body 26 is located in the recess 8;
is pivotably supported in the upright position located in the recess 27 so as to be swingable. That is, as shown in FIG. 6, which is a cross-sectional view of the second adjusting body 26, the protrusion 31 provided on each leg piece 30 of the substantially U-shaped resin body 29 is connected to the hole 32 provided on the opposite wall of the recessed portion 27. It is pivoted by inserting it into the
The second adjusting body 26 has terminal fittings 33, 33 on opposite end surfaces in the length direction of the recess 8, and each of the terminal fittings is U-shaped, with one side 34 of the terminal fittings 33, 33 being opposite to each other in the longitudinal direction of the recess 8.
The other side 35 located at the opposite end surface has elasticity and is fixed to the hollow space 3 of the resin body 29.
It is facing 6. Further, a resistor 37 is attached within the resin body 29 to connect the pair of terminal fittings 33, 33.

In the above configuration, the first adjustment body 15 is
the second adjusting body 26
By placing the battery in the upright position so that its tip 28 is located in the recess 27, the single batteries 5 and 2 are inserted into the battery storage recess 4 and connected to the contact piece metal fitting 12 and the contact piece spring 13. charging becomes possible.

When charging the cell 9, the first adjustment body 15 is placed in the upright position as shown in FIG.
By setting the adjustment body 26 to the upright position and inserting the cell 9 into the battery storage recess 4, the cell is placed in the first position.
The contact piece metal fitting 12 and the contact piece spring 13 are connected via the adjusting body 15.
connected to. When charging the cell 7, the positions of the first and second regulators 15 and 26 are the same as when charging the cell, but since the cell 7 is inserted into the recess 8, the cell 7 is connected to the contact piece metal fitting 12 and the contact piece spring 14 via the first adjusting body 15 .

When charging a small battery 38 that is shorter than a cell 7, as shown in FIG. By doing so, the small battery 38
