In the above-mentioned conventional battery case, when the case body is advanced and retracted, it may be moved straight back and forth in the front-rear direction. Pushes the left and right wall portions of the case cover outward in the left-right direction. The claws are elastically deformed outward in the left-right direction and then engage the lower surface of the case plate. Therefore, when the left and right wall portions of the case cover are pushed outward in the left-right direction, the claws may come off from the lower surface of the case plate. .

In view of the above problems, it is an object of the present invention to provide a battery case in which the case cover does not come off the case plate even when the case body is inclined when the case body is moved forward and backward.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a case body that can move forward and backward while holding a battery with respect to a body of a device that uses a battery as an operating power source, and a case body that includes a case body. A case plate which is attached and on which the case body is mounted so as to be able to move forward and backward, is engaged with the case plate from above, and covers the case body to restrict the movement of the case body in the left-right direction and the lifting of the battery from the case body. In a battery case comprising a case cover, a hook on a lower edge of the case cover, which is once elastically deformed outward in the left-right direction when the case cover is engaged with the case plate, and then engages with a locking portion formed on the case plate. And a protrusion that engages with the case plate in a state where the hook is engaged with the locking portion and that restricts the movement of the hook to the left and right sides is formed near the hook. .

When the hook is engaged with the locking portion formed on the case plate, it does not come off from the locking portion of the case plate unless it is moved outward in the left-right direction. By forming the protrusions near the claws, even if the claws try to move outward in the left-right direction, the protrusions formed in the vicinity do not move outward in the left-right direction, so the claws do not move outward in the left-right direction. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a gas stove, which is a device using a battery as an operating power source. An opening 12 is formed in a front panel 11 of the gas stove 1, and a case main body 2 of a battery case for storing a battery is stored through the opening 12. The gas stove 1 includes a temperature sensor 13 for detecting the bottom temperature of the pot and a thermocouple 14 for detecting ignition and misfire.
A control device (not shown) for controlling the open / close state of an electromagnetic safety valve (not shown) based on a detection signal from the controller is built in. The control device and the ignition device (not shown) operate using a battery housed in the case body 2 as a power supply.

Referring to FIGS. 2 and 3, the battery case is provided with a case plate 3 attached to the main body of the gas stove 1 in addition to the case main body 2, and is engaged with the case plate 3 from above. And a case cover 4 that covers the main body 2 from above and restricts movement of the case main body 2 in the left-right direction and prevents the battery from floating from the case main body 2.

At the front end of the case body 2, the opening 1
The cover plate 21 for closing the cover 2 is integrally attached. A window hole 21a is formed in an upper portion of the cover plate 21, and a lever piece 22 is provided from the rear to the front through the window hole 21a.
Is protruding. The lever piece 22 is connected to a lock piece 23. The lock piece 23 is formed so as to be able to elastically swing up and down around a position away from the lock piece 23 by a predetermined distance. Therefore, when the case body 2 is further pushed in from the state shown in FIG. 3, the lock pieces 23 ride on the front edge of the case plate 3 and then enter the lock holes 31 formed in the case plate 3. Then, the lock piece 23 engages with the front edge of the lock hole 31 so that the case body 2 cannot be pulled out forward. When the lever piece 22 is pulled upward in this state, the lock piece 23 connected to the lever piece 22 is simultaneously pulled up and comes off the lock window 31. Then, the lock piece 23 does not engage with the lock hole 31, and the case body 2 can be pulled forward as it is.

On the bottom surface of the case body 2, a slope 24 is formed which is inclined downward from left and right inward with respect to the case body 2 insertion / removal direction. And left and right slope 2
A plurality of drain holes 25 penetrating the bottom surface of the case main body 2 are formed in the water collecting portion 24a, which is the lowest part of the bottom surface of the case main body 2 and is sandwiched between the case main bodies 4. The water collecting part 2
4a is inclined downward in the front-rear direction toward the drain hole 25, and water collected at the center along the left and right slopes 24 is further divided in the front-rear direction and collected in the drain hole 25. On the upper surface of the case plate 3, a longitudinal groove 33 is formed in the front-rear direction so as to be located below each of the drain holes 25. The concave groove 33 is formed so that the depth increases from the rear end side to the front end side, and an opening 32 is formed in the front end portion.
Are formed. Therefore, even if a liquid such as water enters the case body 2, the case body 2 passes through the drain hole 25.
And is not accumulated in the case main body 2. The liquid discharged from the drain hole 25 is collected in the groove 33 and drained from the opening 32. By the way, the position of the water collecting part 24a is determined by the electrodes 26a and 26b, the extraction electrode 26c,
It is set at a position lower than the position of any lower edge of the connection portion 26d, and no electric leakage occurs between the electrodes 26a and 26b via water etc. even before water etc. is discharged from the drain hole 25. .

A pair of electrodes 26a and 26b facing each other are attached to the case body 2. A metal spring 27 is attached to the rear electrode 26b. When two batteries are stored in the case main body 2 in series, the positive electrode of the battery is pushed to the electrode 26a as shown in FIG. Contact An extraction electrode 26c was attached to the rear side of the electrode 26b at a predetermined interval. Then, the electrode 26a and the extraction electrode 26c were electrically connected via the connection portion 26d. The electrode 26a, the extraction electrode 26c, and the connection portion 26d
And are integrally formed.

Referring to FIG. 5, a pair of front and rear engagement hooks 41 project from the bottom side of the left side of case cover 4. Inserted from. Then, the case cover 4 is in a state where it can rotate clockwise as viewed from the front centering on the engagement portion between the engagement hook 41 and the window hole 34. On the other hand, a pair of front and rear projections 42 is provided on the right bottom of the case cover 4. Similarly, a pair of front and rear claws 43 are formed on the outer side surface of the right bottom side so as to be elastically deformable outward. On the other hand, the case plate 3 is formed with a window hole 35 into which the projection 42 is inserted and a notch 36 into which the claw 43 is inserted. Therefore, the case cover 4 is
When the rotation is made about the engagement portion between the hole and the window hole 34, the projection 42 is first inserted into the window hole 35, and then the claw 43 enters the notch 36, and the claw 43 is a locking portion. Case plate 3
Engages the lower surface of. Then, the case cover 4 is firmly engaged with the case plate 3 and does not come off. However, when the right side wall of the case cover 4 is pushed outward, the claw 43 moves outward because the claw 43 is integrally formed on the right side wall, and the engagement of the claw 43 with the case plate 3 is released. There is a risk. For example, when the case main body 2 is pushed to the right while the case main body 2 is inserted approximately half in the case cover 4, the case main body 2 is pushed rightward to the right side wall of the case cover 4 via the case main body 2. Force acts. However, in the present embodiment, since the projection 42 is inserted into the window hole 35, the projection 42 is engaged with the window hole 35 even if a force is applied to push the right wall toward the right side. The right side wall does not move outward. Therefore, the claw 43 is artificially
The claw 43 does not come off the case plate 3 unless the work is removed from the case plate 3. However, the claw 43 is shown in FIG.
As shown in FIG. 5, the base of the claw 43 is formed by applying a force acting outward from the lower side of the case plate 3 to the tip of the claw 43 because it is formed in a leg shape from the side surface of the case cover 4. And the claw 43 can be removed from the case plate 3.

[0013] Flanges 28 are formed on both sides of the case body 2. A guide portion 44 is formed on the inner peripheral surface of the case cover 4 so as to face the flange portion 28 from the left and right sides and from above with a small gap. Therefore, when the case body 2 is taken in and out, the case body 2 slides on the case plate 3 in a state where the movement in the left-right direction and the up-down direction is restricted by the guide portion 44.

Since the battery in the case body 2 is urged by the spring 27, if the urging force of the spring 27 acts obliquely on the battery, there is a possibility that the battery will only be allowed to move upward. Therefore, the ceiling surface 48, which is the inner peripheral surface of the case cover 4, is formed in a cylindrical shape in accordance with the shape of the battery, so that only a small gap is formed between the battery and the ceiling surface 48. Even if the battery is going to float, the ceiling surface 48 prevents the battery from rising. On the other hand, it is necessary to connect the electric wire 5 for supplying power to a control device (not shown) to the electrode 26b and the extraction electrode 26c. The electric wire 5
It is necessary to provide a long slit-shaped opening in the direction of movement of the case main body in order to connect the two. However, when the opening is formed on the center line of the case cover 4, when the battery rises from the case body, the portion immediately above the battery that most effectively prevents the battery from rising is removed because of the slit-shaped opening. Therefore, in the present embodiment, the slit opening 45 is opened at a position shifted rightward from the center line of the case cover 4. Since the slit opening 45 is provided so as to be shifted to the right side in this manner, the extraction electrode 26c is
It was attached to be located on the right side of. However, the slit opening 45 may be provided shifted to the left, and in that case, the extraction electrode 26c is attached so as to be located on the left of the electrode 26b.

A push claw 46 which is elastically deformable in the front-rear direction is formed on the inner wall of the case cover 4. When the case body 2 is pushed into the gas stove 1 and stored, as described above, the lock pieces 23 enter the lock holes 31 and engage with each other. Therefore, the rear end face of the case body 2 is urged toward the front by the push claws 46 so that the lock piece 23 is pressed against the front edge of the lock hole 31 so as not to rattle.

As described above, the cover plate 21 is provided with the window hole 21a through which the lever piece 22 is inserted. It is conceivable that water or the like splashes on the front surface of the gas stove 1. At this time, if water or the like enters the inside of the battery case through the window hole 21a, it causes an undesired short circuit or the like. In view of this, a fixing plate 47 covering the entire width in the left-right direction is provided in the upper part of the mouth of the case cover 4 in a hanging manner, and a protection plate 29 also covering the entire width in the left-right direction is erected on the case body 2. When the case body 2 is pushed into the storage position, the fixing plate 4
The protection plate 29 is formed so as to lightly contact the front surface of the nozzle 7 or to face it with a small gap. With this configuration, even if water or the like enters through the window hole 21a, the protection plate 29 prevents the water or the like from entering any further. Further, even if water or the like attempts to pass over the protection plate 29, the fixing plate 47 prevents water or the like from entering.

The ceiling surface 48 of the case cover 4 is close to the battery and prevents the battery from floating as described above. However, when the case main body 2 is pulled out and the case main body 2 is returned to the gas stove 1 with the new battery set in the case main body 2 and the batteries are already slightly lifted up, the battery is attached to the front end of the ceiling surface 48. It is conceivable that the battery case 2 cannot be pushed any further due to the collision. Therefore, as shown in FIG. 3, a tapered inclined surface 48a is formed at the front end of the ceiling surface 48. Thus, even if the battery is slightly lifted and the case body 2 is to be returned to the gas stove 1, the battery is not caught by any part of the case cover 4, and is pushed down by the inclined surface 48 a while being pressed down by the inclined surface 48 a. It is possible to proceed to the back of the cover 4.

As described above, penetration of water or the like is prevented by the fixing plate 47. The lower end of the fixing plate 47 is extended downward from that shown in FIG. 3 so that the position of the lower end of the fixing plate 47 is substantially the same as the upper end position of the ceiling surface 48, as shown in FIG. When the lower end of the fixing plate 47 is extended in this manner, the portion overlapping with the defense plate 29 increases, so that intrusion of water or the like can be more effectively prevented.

Incidentally, a rib 45a is provided upright on one side edge of the slit opening 45. In the above embodiment, since the ribs 45a are formed to increase the mechanical strength of the case cover 4, the height of the ribs 45a may be several mm. On the other hand, if the connector 51 for connecting the electric wire 5 to the electrode 26a and the extraction electrode 26c protrudes above the rib 45a, the connector 51
Moves while projecting above the rib 45a,
There is a possibility that the connector 51 may catch other wires and harnesses. Therefore, as shown in FIG. 7, it is desirable to make the height of the rib 45a about 20 mm so that the connector 51 is hidden by the rib 45a. In addition, even if the case main body 2 is put in and out while the electric wire 5 connected to the connector 51 protrudes from the rib 45a, the electric wire 5 is easily bent, so that there is no problem that the electric wire 5 catches on another electric wire or harness.

If the case body 2 is completely detached from the gas stove 1 when the case body 2 is pulled out forward, the electric wire 5 is pulled and the electric wire 5 is disconnected or the contact at the connector 51 is made. Failure may occur. Therefore, a retaining piece 4a is formed on the case cover 4 as shown in FIG.
The case body 2 is brought into contact with the retaining piece 4a.
Can not be pulled out from the front side. In the above-described embodiment, the hook 43 is engaged with the lower surface of the case plate 3. However, an opening through which the hook 43 enters the bent piece around the case plate 3 is provided. You may make it engage. In the above embodiment, the projection 42 is provided so as to project downward, and the projection 42 is inserted into the window hole 35 formed in the case plate 3.
Is inserted to restrict the movement of the claw 43.
The movement of the claw 43 is limited by providing a protrusion projecting upward from the inside and making the protrusion projecting horizontally contact the protrusion from the inside in the left-right direction with the case cover 4 attached to the case plate 3. Can also.

In the above embodiment, the present invention has been described by taking a gas stove as an example. However, the present invention can be applied to all other appliances using a battery as a power source, such as a cooker and a heater.

[0022]

As is apparent from the above description, according to the present invention, since the protrusion restricting the outward movement in the left-right direction is formed in the vicinity of the hook, the case main body is inclined when storing the case main body. There is no danger that the claws will come off the case plate even when tilted.
