Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a locking device for a removable opening/closing body which is attached to an opening provided in a vehicle body so that the opening/closing body can be opened/closed and detached.

Conventional technology and its problems Conventionally, this type of locking device was
As described in Publication No. 50414, the front edge of the opening/closing body is locked to the inner peripheral edge of the roof opening hole via a removable hinge, and the rear edge is provided with a toggle type locking device,
It is known that the opening/closing body is attached so that it can be opened/closed and detached. That is, when opening/closing the opening/closing body, the tip of the handle is pulled to make a toggle motion via the link, and the opening/closing body is opened/closed using the front edge as a fulcrum, and when the opening/closing body is attached/detached, the locking device is activated. The connecting shaft is compressed by pressing from both sides, the detachable pins of the links provided at both ends of the connecting shaft are removed from the bearings on the roof side, and the opening/closing body can be removed from the roof opening hole.

However, in the case of the above structure, the links and detachable pins protrude from both sides of the connecting shaft, and the tip of the handle protrudes for a long time, making the entire locking device large and exposing it inside the vehicle, spoiling its appearance. There were flaws.

Therefore, it may be possible to miniaturize the locking device by providing the detachable pin only on one end of the connecting shaft and cutting off the tip of the handle.
In this case, since the connecting shaft and the tip of the handle would be close to each other, there was a risk that the connecting shaft would be erroneously pressed when attempting to open or close the opening/closing body, and the opening/closing body would fall off.

Purpose of the Invention The present invention was made in view of the problems of the prior art, and its purpose is to miniaturize the lock device as much as possible, and to provide a removable opening/closing device that eliminates the risk of the opening/closing body accidentally falling off during opening/closing operations. The purpose is to provide a body locking device.

Structure of the Invention In order to achieve the above-mentioned object, the present invention locks one side edge of an opening/closing body to one side edge of an opening provided in the roof with a removable hinge, and locks the opposite side edge to one side edge of an opening provided in the roof. A removable opening/closing body connected via a removable locking device includes a handle having one end pivotally attached to the opening/closing body and a pivot provided at the other end, and a handle protruding parallel to the pivot at one end. a link having a detachable pin, the other end of which is slidably inserted into the support shaft; a base plate fixed to the roof side and provided with a bearing that supports the detachable pin in a detachable manner; a detachment button that is provided to be movable forward and backward with respect to the support shaft and that can push the link in a direction in which the detachment pin escapes from the bearing;
A spring biases the link in the direction in which the detachable pin engages with the bearing, and the handle is provided with a spring that opposes the side of the link in the vicinity of the fully open and fully closed positions of the opening/closing body to prevent the link from moving in the withdrawal direction. It is equipped with a stopper surface.

Description of the Embodiment In Fig. 1, 1 is a roof, 3 and 4 are openings provided on both sides of the roof 1, and 6 and 6' are glass plates that cover the openings. The side glass plate 6 is an opening/closing body that can be opened and closed as shown by the dashed line in FIG.

A shaft 8 is fixed to the inner edge 6a of the opening/closing body 6 via a support 7, as shown in FIG. 2, while the shaft 8 is rotatably attached to the peripheral edge of the roof opening hole 3. A recess 9 is formed to support the shaft 8 in a removable manner, and the shaft 8 and the recess 9 constitute a removable hinge.

Two pairs of locking devices 10 shown in FIGS. 2 to 5 are provided on the outer edge 6b of the opening/closing body 6. That is, 11 is a bracket fixed to the inner surface of the outer edge 6b of the opening/closing body 6, and 12 is a handle whose upper end (one end) is pivotally connected to the bracket 11 via a shaft 13. A gate-shaped wall portion 14 is integrally formed, and this wall portion 1
A support shaft 15 is fixed to the lower end (other end) of 4 in the width direction. Further, a notch 16 is formed at the lower end of the handle 12, and the inner surface of the wall portion 14 and the inner surface of the notch 16 form stopper surfaces 14a, 16.
It forms a.

Reference numeral 20 denotes a link having a diamond-shaped cross section, and has a detachable pin 21 projecting laterally at one end, and the other end is slidably inserted into the support shaft 15. A spring 23 is provided between the link 20 and the inner surface of the wall 14 of the handle 12, and the spring 23 is fitted onto the support shaft 15. The spring 23 biases the link 20 to the left in FIG. ing. As shown in FIGS. 4 and 5, leaf springs 24 are attached to both sides of the inner surface of the wall portion 14 with rivets 25, and these leaf springs 24 are attached to minute recesses formed on both sides of the link 20. 22, and holds the link 20 with a sense of moderation when fully closed.

Reference numeral 25 denotes an attachment/detachment button that is fitted into the tip of the support shaft 15 so as to be freely retractable.The tip flange portion 26 of this attachment/detachment button 25 abuts the left side surface of the link 20 and is prevented from coming off against the wall portion 14. has been done.

30 is a base plate fixed to the peripheral edge of the roof 1 with bolts 31, and an annular bearing 3 is attached to the tip.
2 is formed, and the detachable pin 21 of the link 20 is removably and rotatably fitted into this bearing 32.

The operation of the lock device 10 having the above structure will be explained. First, when opening the opening/closing body 6, pull up the lower end (other end) of the handle 12 in the counterclockwise direction in FIG.
Disengage from the As a result, the link 20 becomes rotatable about the detachable pin 21, so the handle 12 connected to the link 20 by the support shaft 15 moves from the state shown by the broken line in FIG. 2 to the state shown by the integral chain line,
Accordingly, the opening/closing body 6 rotates upward about the shaft 8 as a fulcrum. When the position shown by the dashed line in FIG. 2 is reached, the link 20 comes into contact with the bottom surface of the notch 16 of the handle 12, so the link 20 and the handle 12 cannot rotate relative to each other anymore, and the opening/closing body 6 is held in the fully open state. be done. When closing the opening/closing body 6, the operation opposite to the above may be performed.

Next, when the opening/closing body 6 is to be removed, the detachment button 25 may be pressed to remove the detachment pin 21 of the link 20 from the bearing 32 of the base plate 30. However, when the opening/closing body 6 is in the vicinity of the fully closed position, even if the attachment/detachment button 25 is pressed, the side surface of the link 20 will not touch the leaf spring 24 or the inner surface of the wall 14 (stopper surface 14).
Since the position is restricted by a), the detachable pin 21 does not come off the bearing 32, and even in the vicinity of the fully open position, the other end of the link 20 does not touch the notch 1 of the handle 12.
Since the movement is restricted by the inner surface (stopper surface 16a) of 6, the link 20 cannot move in the left-right direction, and the detachable pin 21 does not come off from the bearing 32. That is, the opening/closing body 6 cannot be attached or detached in either the fully closed or fully opened state. This is because the lower end (other end) of the handle 12 and the detachable button 25 are located close to each other, and when the lower end of the handle 12 is operated to open and close the opening/closing body 6, the detachable button 25 may be pressed by mistake. Opening/closing body 6
This is to eliminate the risk of it falling off.

Therefore, pull up the handle 12 and move the attachment/detachment button 25 within the range of angle θ from the broken line position in FIG.
By pressing , the restriction on both sides of the link 20 is removed, so the link 20 moves to the right in FIG.
2 is disengaged, and the opening/closing body 6 can be removed from the roof 1. That is, the opening/closing body 6 can be attached and detached only at an intermediate position between fully closed and fully opened, which is safe.

As described above, the lower end (other end) of the handle 12 does not protrude as long as in the conventional case, and the vertical dimension can be reduced. Since the dimension in the direction can be reduced, the lock device 10 can be made smaller as a whole, and even if it is exposed inside the vehicle interior, the appearance will not be spoiled so much. In particular, since the link 20 is bent to have a rhombic cross-section, a space for arranging the spring 23 can be secured even if the width of the handle 12 is reduced, and the locking device 10 can be further downsized.

Although the above embodiment shows the case where the lock device 10 is applied to a sunroof, the present invention is not limited to this.
For example, it may be applied to a quarter window.

Effects of the Invention As is clear from the above description, according to the present invention, a detachable pin is provided at one end of the link that can be freely fitted into and detached from the bearing of the base plate, and the other end of the link is provided with a support provided at the other end of the handle. Because it is inserted into the shaft, parts such as links and handles can be made more compact compared to conventional models in which links and detachable pins are protruded from both ends of a long connecting shaft, and the tip of the handle is long. The lock device can be miniaturized as a whole.
In addition, the movement of the link in the withdrawal direction near the fully open and fully closed positions is restricted by the stopper surface of the handle, and the opening/closing body can be attached and removed only at an intermediate position between fully open and fully closed, so it is possible to prevent the link from moving in the fully open or fully closed position. There is no risk of the opening/closing body falling even if you accidentally press the attachment/detachment button.
