Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a guide and locking device that guides a sliding member and locks it in at least two positions.

"Prior Art and its Problems" For example, various types of battery cover locking devices are known that open and close the opening of the battery case.
One known type is a type in which the battery cover itself is provided with a locking member that is slidable between a locking position and an unlocking position. This locking member requires at least a click mechanism to lock it in the locking position and the unlocking position.
Some kind of locking means was provided between the lock member and the support member. However, all conventional products have three or more parts and are complicated to assemble.
Additionally, bonding work is required, which poses a problem of high component costs and high assembly costs.

``Purpose of the invention'' The purpose of the invention is to propose a sliding member guide and locking device that can be composed of only two members: a sliding member and its supporting member, and to improve assembly workability and reduce parts costs. With the goal.

"Summary of the invention" The present invention includes a sliding member that includes a pair of elastic legs that can be elastically expanded and contracted, a pair of protrusions formed to face each other on the inner surface of the pair of elastic legs, and A slope formed on both sides of the part and a retaining protrusion protruding inwardly formed at the tips of a pair of elastic legs are provided respectively. It is located between a hole that can be inserted freely, a sliding guide surface of a sliding member following this hole, and a pair of elastic legs of the sliding member, and the elastic legs expand and contract by engaging with and disengaging from the slope of the protrusion. The present invention is characterized in that it is provided with a central protrusion and a retaining support portion that guides the pair of elastic legs by sandwiching them between the sliding guide surface and the sliding guide surface at a position inward from the retaining protrusion.

This guide and locking device is composed of only two members, a sliding member and a supporting member, and is extremely easy to assemble.

If the pair of retaining protrusions at the tips of the pair of elastic legs of the sliding member are formed into a key shape, the sliding member can be prevented from coming off more reliably.

For example, as described above, this sliding member guiding and locking device uses the supporting member as an opening/closing lid that opens and closes the opening of the battery case, and the sliding member holds the opening/closing lid in the lock position and the unlocked position. It can be used as a locking member.

``Embodiments of the invention'' The invention will be described below with reference to illustrated embodiments. 1 to 4 show embodiments of the present invention. In this embodiment, the present invention is applied to the locking mechanism of the opening/closing lid 10 of the battery storage case 1. It is pivoted on the side. A locking hole 3 is formed on the other side of the opening 2, into which a locking protrusion 21 of a locking member 20 slidably supported on the opening/closing lid 10 engages and disengages. The lock member 20 is a sliding member, and the opening/closing lid 1
0 is its supporting member.

The opening/closing lid 10 has an insertion hole 12 approximately in the center thereof.
is worn. This insertion hole 12 is connected to the opening/closing lid 1.
Sliding guide surface 14 on the lower surface of the notch 13 on the outer surface of 0
The lock member 20 can be inserted through this insertion hole 12. Further, the opening/closing lid 10 has a central protrusion 16 and a retaining support portion 17 protrudingly formed on the sliding guide surface 15 side thereof.

The lock member 20 is inserted into the opening/closing lid 10 from the insertion hole 12.
a flat plate portion 22 that is inserted into the interior and guided by the sliding guide surface 15; a finger hook portion 23 that is located within the notch 13 and guided by the sliding guide surface 14;
A lock portion 24 having the lock protrusion 21 is bent in an L shape relative to the finger hook portion 23. A finger rest recess 25 is formed in the finger rest 23 .

A pair of elastic legs 26 that can be elastically expanded and contracted are formed on the flat plate portion 22.
Protrusions 27 corresponding to each other are formed on the inner surface of each of the members 6 . This protrusion 27 has slopes 28 on both sides thereof, that is, on both sides in the direction of extension of the elastic legs 26, facing oppositely to each other. This slope 28 engages with and disengages from the central protrusion 16 of the opening/closing lid 10, and functions to lock (stably hold) the locking member 20 in the locked position and the unlocked position.

A retaining protrusion 29 is formed at the tip of each of the pair of elastic legs 26. The pair of retaining protrusions 29 have a symmetrical key shape, and have a slope 30 whose diameter gradually increases inward, and a key portion 31.

The above-mentioned retaining support portion 17 formed on the opening/closing lid 10
is provided with a protrusion 18 which clamps and supports the elastic leg 26 between it and the sliding guide surface 15 at a position inside the retaining protrusion 29.

In this device having the above-mentioned structure, when the locking member 20 is assembled to the opening/closing lid 10, the elastic legs 26 are inserted into the opening/closing lid 10 from outside through the insertion hole 12. Then, the retaining protrusion 29 at the tip of the elastic leg 26 comes into contact with the retaining support portion 17, and the slope 3
The pair of elastic legs 26 are elastically deformed and opened by the guide 0. When the locking member 20 is further pushed in in this state, the retaining protrusion 29 and the retaining support portion 17 are eventually disengaged, and the elastic leg 26 returns to its free state due to its elasticity. In this free state, the key part 31 of the retaining protrusion 29 is in the retaining support part 17.
The locking member 20 is in an engaged position with the locking member 20, thereby preventing the locking member 20 from coming off. Note that the retaining support portion 17 is formed with a retaining slope 19 that engages with the key portion 31 to more reliably prevent the locking member 20 from coming off. That is, simply applying a tensile force to the locking member 20 will not cause the elastic legs 26 to open and, therefore, the locking member 20 will not come off.

The protrusions 27 of the pair of elastic legs 26 are connected to the center protrusion 16
The lock member 20 is locked in two positions, a lock position and an unlock position, by a pair of slopes 28 that engage with the lock member 20. That is, in the state shown in FIG. 1 in which the lock member 20 is pushed in, the inner slope 28 of the pair of slopes 28 of the protrusion 27 engages with the center protrusion 16 at an intermediate position. In order to pull out the lock member 20 from this state, a force must be applied to elastically open the elastic leg 26 due to the relationship between the slope 28 and the central protrusion 16, so this position is one stable position.

Further, in the state shown in FIG. 2 with the lock member 20 pulled out, of the pair of slopes 28 of the protrusion 27, the slope 28 on the entrance side engages with the center protrusion 16 at an intermediate position. In order to push in the lock member 20 from this state, it is necessary to apply a force to elastically open the elastic leg 26 due to the relationship between the slope 28 and the central protrusion 16, so this position is another stable position. .

That is, in order to move the locking member 20 between the locking position shown in FIG. 1 and the unlocking position shown in FIG.
A process of engaging the apex portion between the pair of slopes 28 with the central protrusion 16 necessarily occurs, and for this purpose a force must be applied to the locking member 20 to open the pair of elastic legs 26. Since such force is not applied to the locking member 20 unless it is applied intentionally, the locking member 20 can be reliably locked in the locked position and the unlocked position. In addition, the lock protrusion 21
fits into the locking hole 3 when the locking member 20 is in the locked position, and escapes from it when the locking member 20 is in the unlocked position.

In the above embodiment, in order to lock the lock member 20 in two positions, the pair of slopes 28 of the protrusion 27 are formed adjacent to each other, but a parallel part is formed between the pair of slopes 28, and the center is centered on this parallel part. By forming one or more shallow grooves into which the protrusion 16 fits, locking can be achieved at three or more positions.

Further, in the above embodiment, the present invention is applied to a locking mechanism for the opening/closing lid of a battery storage case, but the present invention can of course be applied to other locking mechanisms using sliding members, as well as to sliding parts in general.

``Effects of the invention'' As described above, the sliding member guide and locking device of the present invention requires only two parts, the sliding member and its support member, and its assembly is performed using a pair of elastic legs of the sliding member. All you have to do is open it and position the retaining protrusion at its tip beyond the retaining portion of the support member. Therefore, parts costs and assembly costs can be reduced.
