Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for an opening / closing body for a vehicle, and more particularly to a locking device for an opening / closing body for a vehicle, which is preferably used for an opening / closing body provided on a roof of a vehicle for ventilation in a vehicle compartment.

[0002]

2. Description of the Related Art Conventionally, as a locking device for such an opening / closing body, one disclosed in, for example, Japanese Utility Model Laid-Open No. 59-146214 is known. This one uses a link that constitutes a toggle mechanism to hold the opening / closing body at its fully closed position and at its fully opened position where one end is pivoted.

[0003]

However, in such a conventional locking device for the opening / closing body, since only the toggle mechanism is used, the state of the fully open or fully closed position beyond the positions of both dead points is provided. There is a problem that it is inconvenient to ventilate in rainy weather because it can only be selected.

An object of the present invention is to provide a lock device for an opening / closing body that can select the opening degree of the opening / closing body in a plurality of stages and can hold the opening / closing body reliably at the selected positions.

[0005]

To achieve the above object, the present invention provides a movable handle member, one end of which is pivotally attached to one of an opening / closing body and a support of the opening / closing body, and one end of which is a movable handle member. A locking device for a vehicle opening / closing body, comprising a connecting member pivotally attached to the other end of the movable handle member and pivotally attached to the abdomen of the movable handle member, the movable handle of the connecting member. An axial groove is formed on the outer periphery of the pivotally connected portion with the member, and the movable handle member is urged so that one end can engage with the axial groove and the other end can project from the outer surface of the movable handle member. It is characterized in that a stop member is provided.

[0006]

According to the present invention, for example, when the movable handle member is rotated through the dead center position from the fully closed state of the opening / closing body, the connecting member also rotates. Then, one end of the locking member provided on the movable handle member engages with the axial groove formed on the outer periphery of the pivotal portion of the connecting member, and the other end projects from the outer surface of the movable handle member. At this engagement position, the rotation of the movable handle member is prevented, and the opening / closing body is maintained in a predetermined opening state. By the way, when further opening is desired, the protruding end of the locking member is pressed to release the engagement with the axial groove, and the movable handle member is further rotated to obtain the engagement with the next axial groove. . By forming a plurality of axial grooves in this way, a plurality of openings can be obtained.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 is a lid having a size that covers an opening 5 formed in a roof 3 of a vehicle. One end of the lid 1 is pivotally attached to the roof 3 via a hinge stay 7 so as to be rotatable. On the other hand, a fixed stay 9 is fixed to the other end. Reference numeral 11 denotes a movable handle member, one end of which is pivotally attached to the end of the fixed stay 9 by a first spring pin 13 and has a substantially boat shape. 15 is a fixing member fixed to the roof 3. The connecting member 19 has a second end at the end of the fixing member 15.
It is rotatably pivoted by a spring pin 17, and the other end is rotatably pivoted by a third spring pin 21 to the middle abdomen of the movable handle member 11. Connection member 1
The other end portion of 9 has a cylindrical shape in which the insertion hole of the third spring 21 is formed, and in the present embodiment, first and second axial grooves 191 and 192 are formed on the outer peripheral portion thereof. .

Further, 23 is a locking member, which is rotatably supported by the movable handle member 11 with a pin 25. A hook-shaped tooth portion 231 is provided at the tip of the locking member 23.
However, a ridge 232 is formed at the rear end of the tooth 2
Reference numeral 31 is engageable with the above-mentioned axial grooves 191, 192, and the raised portion 232 is set so as to be able to project from the outer surface of the movable handle member 11 through the opening 111 formed therein. Further, the locking member 23 is made of resin, and a tongue piece 233 is integrally formed behind the tooth portion 231 to give the locking member 23 a rotational force around the pin 25.

In this embodiment having the above-mentioned structure, FIG.
In the fully closed state of the lid 1 shown in FIG. 3, the third spring pin 21 is present at a position beyond the dead center on the line connecting the first and second spring pins 13 and 17 to keep the lid 1 in the fully closed state. are doing.

When the tip end of the movable handle member 11 is rotated from this state, the movable handle member 11 goes over the dead center and the connecting member 19 rotates about the spring pin 13 as the center of rotation and the second spring pin 17 as the center of rotation. In addition, the connecting member 19 and the movable handle member 11 are the third
The spring pin 21 rotates relative to the center of rotation. Then, the locking member 2 pivotally attached to the movable handle member 2
The third tooth portion 231 slides on the cylindrical outer peripheral portion of the connecting member 19 and then engages with the first axial groove 191 that can be set arbitrarily.

Thus, the relative rotation between the connecting member 19 and the movable handle member 11 is prevented, and the intermediate opening position of the lid 1 shown in FIGS. 1 and 5 is obtained.

The tooth portion 231 and the axial grooves 191, 192
In the engaged state with, the ridge 232 projects from the outer surface of the movable handle member 11 through the opening 111,
When the above-mentioned intermediate opening position is stopped to bring it into a fully open or fully closed state, the protrusion 23 is resisted by the biasing force of the tongue piece 233.
2 may be pressed to release the engagement of the tooth portion 231.

In this embodiment, the lid 1 shown in FIG.
The tooth portion 231 of the locking member 23 is set to engage with the second axial groove 192 at the fully open position.

By increasing the number of axial grooves formed on the cylindrical outer peripheral portion of the connecting member 19, it becomes possible to easily hold the lid 1 at a plurality of opening positions.

[0016]

As is apparent from the above description, according to the present invention, it is possible to easily obtain a plurality of opening / closing positions of the opening / closing body and securely hold the opening / closing body at the opening positions. Further, an unlocking operation can be performed in the vicinity of the rotating operation portion of the movable handle member, and a series of operations can be performed with one hand.
