Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a locking device for a sliding glass for a vehicle window that moves laterally.

(Prior Art and its Problems) For example, a van, such as a wagon, is equipped with a locking device that moves a sliding window glass laterally.

Conventional locking devices can be unlocked with just one operation of a human finger. Therefore, there is a drawback that the lock can be unlocked by unauthorized persons from outside the vehicle, such as by inserting a wire through the gap in the locking device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a locking device for a slide glass for a vehicle which can be unlocked only by two operations, which eliminates such conventional drawbacks.

(Means for Solving the Problem) According to the present invention, there is provided a sliding knob operated by a finger and biased by a spring in a locking device fixed to a sliding glass of a vehicle window; A release member is provided which is allowed to swing by the movement of the knob and is pushed by a finger, and when the claw member connected to the release member via a spindle comes out of the hole of the strike fixed to the vehicle body, the slide glass is removed. It was configured to be open.

(Example) The lock device 1 of the present invention includes a case cover 2 covering the outside, a release member 3 swingably supported inside the case cover, a claw member 4 swingably supported by the release member, It consists of a sliding knob 5 and a leaf spring 6 that are slidably attached to the case cover.

As shown in FIG. 1, the base portion of the case cover 2 is fixed to the outer surface of a slide glass 7 of an automobile using an auxiliary tool 8 with screws or the like.

A release member 3 is swingably supported inside the case cover 2 by a support shaft 9. As clearly shown in FIG. 7, the release member 3 has a triangular abutting portion 10 on its front surface and an abutting surface 11 (the function of which will be described later) at its tip. Further, the main body portion of the release member includes a thick portion having an abutting surface 13 on the front surface, and a thin portion having a cutout to form a cavity 12.

The release member 3 is constantly pressed rearward by the spring 14 wound around the support shaft 9, and the lower end 2 of the rear wall of the release member
0 is stopped by contacting the base portion of the case cover 2. Both ends S, , S2 of the spring 14
is shown in Figure 4.

A claw member 4 is swingably supported by the release member 3 by the aforementioned support shaft 9. The claw member 3 is normally pressed against the release member 3 by the leaf spring 6, which is provided under the claw member 3 with one end fixed to the case cover 2 and the other end free.

A claw 15 is provided at the tip of the claw member 4, and the instruction is strike 1.
6 (FIG. 2 shows the fitted state). Further, the release member 3 of the claw member 4
A triangular protrusion 18 is provided on the surface facing the , and the protrusion is provided with an abutting surface 19 (FIG. 7). The contact surface 19 is normally in contact with the contact surface 11 of the contact portion 10 of the release member 3 due to the leaf spring 6 (this state is shown in FIG. 2).

The sliding knob 5 can slide in a slot 21 provided in the case cover 2 parallel to the base of the case cover, ie parallel to the glass 7 of the motor vehicle. The sliding knob consists of a knob 25 that can be pinched with fingers and a handle 26 fixed thereto, and the handle 26 passes through and slides through the aperture 21 of the case cover.

A guide hole 22 provided in the handle 26 slides along a guide pin 23 whose both ends are fixed to the case cover. A compression spring 24 is provided around the guide pin 23, and the sliding knob 5 is normally pushed to the position shown in FIG. 4 by this pressing force. At this time, the tip of the handle 26 of the sliding knob is connected to the release member 3.
It is in contact with the contact surface 13 of. In FIG. 4, it can be seen that when the sliding knob 5 slides in the opposite direction, the tip of the handle 26 comes off the contact surface and can enter the cavity 12 of the release member 3.

Next, the operation will be explained. The locking device 1 of the present invention is fixed to a sliding window glass 7 of an automobile that moves laterally,
A claw member 4 of the locking device 1 is locked into a hole 17 of a strike 16 fixed to the vehicle body, and released therefrom.

First, the steps of opening and closing the slide glass of an automobile will be explained. In FIG. 1, the locking device 1 of the present invention moves to the right together with the glass 7, and is in a state where the window has just finished closing, that is, just before automatic locking. When the inclined surface 4 at the tip of the pawl member 4 comes into contact with the strike 16, the pawl member 4 is rotated clockwise about the support shaft 9 against the elasticity of the leaf spring 6, resulting in the state shown in FIG. If the state advances further from the state shown in FIG. 1, the claw 15 of the claw member 4 will fit into the hole 17 of the strike 16 and be automatically locked.

FIG. 2 shows this locked state. In this state, the pawl member 4 is pressed counterclockwise by the leaf spring 6, so that the pawl 15 cannot naturally come off from the hole 17 of the strike 16. Further, the tip of the handle 26 of the sliding knob 5 is in contact with the contact surface 13 of the release member 3. Further, the contact surface 11 of the release member 3 is in contact with the contact surface 19 of the claw member 4.

FIG. 3 shows the release operating state. When you first pinch and slide the sliding knob 5 with your fingers, that is, slide it downward to the chain line position in FIG. 4 (this is referred to as the first operation), the sliding knob 5 is inserted into the empty space 12 of the release member 3. At this time, when a force P is applied to the release member 3 from behind with a finger (referred to as a second operation), the release member 3 rotates clockwise around the support shaft 9 against the elasticity of the spring 140.
The abutment surface 11 of the release member presses the abutment surface 19 of the pawl member to rotate the pawl member 4 clockwise in FIG. 15 escapes from the hole 17 of the strike 16.

In this way, the above two operations result in an unlocked state. At this time, the window can be opened by pulling the glass 7 to the left.

(Effects of the Invention) As described above, since the locking device of the present invention cannot be unlocked unless the sliding knob and the release member are operated in two movements, it is effective in preventing unlocking due to unauthorized operation. It is.
