Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a sliding window of a vehicle, and more particularly to an improvement of a lock body that engages and disengages from a striker.

This type of lock device generally has a striker with a locking hole on the side of the window frame that supports the slide glass so that it can be slid open and closed, and a lock body that has a lock body with an engaging pawl that engages and disengages with the locking hole on the slide glass side. It is set up and configured. The engaging pawl of the lock body is biased toward the locking hole of the striker, and a locking load is obtained by the biasing force, but in conventional products, for example, the lock body made entirely of synthetic resin material, It is difficult to increase this locking load, and therefore, although the releasing operation can be performed with a small force, there is a problem in that sufficient locking strength cannot be obtained. Further, if the entire movable part having the engaging pawl is made of a metal material having spring properties, there are problems with rust, the strength of the engaging pawl itself, or the appearance.

Furthermore, with conventional products, the position of the engaging claw is unstable, and when the slide glass is slid from the unlocked position to the locked position, the engaging claw cannot be securely locked into the locking hole on the wind frame side. There is a risk. This is particularly likely if the spring biasing force changes over time.

The present invention solves these problems with conventional products by providing a striker with a locking hole on the wind frame side, and attaching the striker to the locking hole on the slide glass, which is supported by the wind frame so that it can be slid open and closed. A locking device for a sliding window for a vehicle is provided with a lock body having a removable engagement pawl, and the lock body is composed of a synthetic resin base and a leaf spring body,
A synthetic resin base includes a base that is closely fixed to the slide glass, a fixed handle and a movable handle that stand up from the base, and a lock that extends from the movable handle toward the striker and has the engaging claw at its tip. The engagement arm is provided with a stopper protrusion that comes into contact with the slide glass and restricts the swinging end of the engagement arm toward the slide glass, and a leaf spring body is provided between the base of the synthetic resin base and the slide glass. A base plate is sandwiched and supported by the base plate, and a rising part is located in the movable handle part continuously from the base plate part. , the engaging pawl is characterized in that it applies a swing biasing force in the direction of fitting into the locking hole of the striker.

According to this locking device for a sliding window for a vehicle, sufficient locking force can be applied to the synthetic resin base by the spring force of the leaf spring body, and the position of the engaging claw can be adjusted to the position where the stopper protrusion contacts the glass. can be stabilized. Therefore, when the glass is moved from the unlocked position to the locked position, the engaging pawl can be reliably engaged with the locking hole on the wind frame side, and in the locked state, the engaging pawl does not fit into the locking hole excessively. This prevents the lock from entering the device and facilitates unlocking.

The invention will now be described with reference to the illustrated embodiments. The sliding window W to which the present invention is applied is installed, for example, in a side sliding door D of a wagon V, as shown in FIG. It has 2,2.

Wind frame 1 has vertical frame parts 1 on both sides.
A striker 3 is fixed to a, and a locking hole 3a for the striker 3 is fixed to the back of the slide glasses 2, 2.
A lock main body 4 that engages and disengages is attached (the partially enlarged view in FIG. 1 is seen from the inside of the vehicle).

The lock body 4 consists of a synthetic resin base 5 and a leaf spring body 6. The base 5 is made of a flexible synthetic resin material such as polypropylene, and includes a vertically long base 5a, a fixed handle 5b raised above the base 5a, and a movable handle raised slightly toward the striker 3 from above the base 5a. part 5c, and an engaging arm part 5e extending from the lower end of the movable handle part 5c toward the striker 3 and having a hook-shaped engaging claw 5d at the tip. A stopper protrusion 5f that comes into contact with the slide glass 2 is continuously provided below the slide glass 2.

The base portion 5a is composed of a peripheral leg portion 5g that comes into contact with the slide glass 2 and a flat plate portion 5h that is apart from the glass 2, and a cylindrical portion 7 of a retainer 7 is placed above and below the flat plate portion 5h.
A contact fixing seat 5i is formed.

Thus, the leaf spring body 6 wraps around the hook portion 6a that fits into the locking groove 5j carved on the inner surface of the base portion 5a of the base body 5, the base plate portion 6b along the back surface of the flat plate portion 5h, and the leg portion 5k whose tip is rounded. U-shaped portion 6c and movable handle portion 5
The U-shaped portion 6c is clamped between the slide glass 2 and the leg portion 5k, and as a result, the leaf spring 6 allows the movable handle portion 5c and engaging arm portion 5
e is urged to swing in the direction in which the engaging claw 5d fits into the locking hole 3a of the striker 3 (in the direction of arrow A in FIG. 2). The end of the swing in the locking direction is regulated at the position where the stopper protrusion 5f comes into contact with the glass 2.

The retainer 7 is positioned on the back side of the slide glass 2, and with the gasket 8 clamped between the retainer 7 and the glass 2, the cylindrical portion 7a is inserted through the hole 2a of the glass 2, and the retainer 7 is inserted into the abutment fixing seat 5i of the base 5. The lock main body 4 is fixed to the glass 2 by bringing it into contact with the fixing seat 5i and screwing the set screw 9 from the surface of the fixing seat 5i.

Therefore, in the present locking device having the above configuration, when opening the slide glass 2, the movable handle portion 5c
All you have to do is pull it toward the fixed handle portion 5b. Movable handle part 5
c. Since the engaging arm portion 5e swings in the direction of arrow B in FIG. 2 to disengage the engaging claw 5d from the locking hole 3a of the striker 3, the slide glass 2 can be opened freely. In addition, when closing, simply sliding the slide glass in the closing direction causes the hook-shaped engaging claw 5d to hit the striker 3, rotate once in the opening direction, and then fit into the locking hole 3a. It can be automatically locked.

In the present invention, since the locking load, that is, the rotational force of the engaging claw 5d in the direction of the arrow A, is applied by the leaf spring body 6, the strength of the leaf spring body 6 can be set appropriately. A sufficiently large locking force can be easily obtained without making operation difficult. The stopper protrusion 5f is effective in preventing the engaging claw 5d from colliding with the glass 2 and being abraded and deformed, and in keeping the locking force constant at all times. Furthermore, since the position of the engaging claw 5d is stabilized by the stopper projection 5f, the engagement between the engaging claw 5d and the locking hole 3a can always be performed reliably.

In the above embodiment, the leaf spring body 6 is fitted into the synthetic resin base body 5 afterward, but it may be inserted into the base body 5 at the same time as the base body 5 is molded.

In summary, in the present invention, the lock body is constructed from a combination of a synthetic resin base and a leaf spring body, and the elasticity of the leaf spring body applies force to the engaging pawl to fit into the striker locking hole. Because of this, it is possible to easily obtain the necessary locking strength without making the synthetic resin base into multiple shapes that are difficult to manufacture. Furthermore, since the leaf spring body is located within the movable handle from the base of the synthetic resin base, the appearance will not be impaired. Furthermore, since the rocking position of the engaging claw in the locking direction is stabilized by the stopper protrusion, when the slide glass is moved from the unlocked position to the locked position, it is securely locked in the locking hole on the wind frame side. can be done. Furthermore, in the locked state, the locking claw does not enter the locking hole excessively, so the locking claw can be easily rotated to release the locked state.
