Description

[Detailed Description of the Invention] "Industrial application field" The present invention particularly relates to a device for opening and closing a window glass such as a side window glass or a sunroof glass of an automobile whose base end side is rotatably supported by a vehicle body. Related to the improvement of.

"Prior Art" As a conventional opening / closing device of this type, for example, the actual open / closed 57-9197
There are those disclosed in Japanese Patent No. 0 and Japanese Utility Model Laid-Open No. 62-101977.

Although not specifically shown, the conventional opening / closing device includes a connecting arm fixed to the free end side of the window glass, a base plate fixed between the opening edges of the vehicle body, and one end of the connecting link. An operation handle movably attached to the operation arm, and the tip end of the connecting arm is rotatably attached to the operation handle, and the tip end of the base plate is rotatably attached to the other end of the connecting link. It is designed to be worn.

Then, in actual use, when the operation handle is grasped and the operation handle is rotated to the base plate side,
Accordingly, the free end of the window glass is moved to the vehicle body side to ensure the closed state of the window glass, and conversely, when the operation handle is pulled and rotated in the direction away from the base plate, In response to this, the free end of the window glass is moved to the outside of the vehicle to ensure the open state of the window glass.

"Problems to be solved by the invention" However, in such a conventional opening / closing device, since the base end side opens and closes the window glass supported by the vehicle body by the turning operation of the operation handle, Not only a considerable force is required for the operation, but also the rotating direction of the operation handle is complicated, so that there is a problem that the opening and closing operation is naturally difficult.

In addition, the conventional opening / closing device can move the window glass to the open position and the closed position to lock it securely, but at the intermediate position, it locks the window glass in the half open state. Since this is not possible, when it is desired to adjust the opening amount, the structure cannot respond to this, and in this respect also, it is considered to be a disadvantageous disadvantage in use.

"Means for Solving the Problems" The present invention was developed in order to effectively solve the problems of the conventional device, and the base end portion of the window is rotatably supported by the vehicle body. Assuming a glass opening / closing device, a housing fixed to an opening edge of a vehicle body, an operation lever movably supported in a guide long groove of the housing and lockable at an arbitrary position, and ends of the housing pivotally attached to each other. And first and second link members that are connected between the free ends of the window glass so as to be extendable and bendable, and a connection link member that connects the pivotally attached portions of the both link members and the operation lever, A configuration is adopted in which the first link member and the second link member are extended or bent by a connection link member that interlocks with the movement operation of the operation lever.

Therefore, in the opening / closing device of the present invention, when the operation lever is moved to the desired extreme end position within the guide long groove of the housing and locked at that position, the interlocking of the connecting link member corresponding thereto is performed. By the action, the first link member and the second link member are accommodated in the housing while bending the pivotally connecting portions thereof in a lateral V shape, whereby the free end portion of the window glass moves to the vehicle body side. Therefore, the closed state of the window glass is surely guaranteed.

Further, when the operating lever is unlocked, the operating lever is moved to the opposite extreme end position in the guide long groove and locked at that position, this time, the connecting link member is interlocked in the opposite direction. , The first link member and the second link member are linearly extended to automatically move the free end of the window glass toward the outside of the vehicle, which ensures that the window glass is fully open. Will be guaranteed.

Then, in the opening / closing device of the present invention, when it is desired to adjust the opening amount of the window glass, the operation lever is moved to
If locked in an intermediate arbitrary position within the guide long groove of the housing, the window glass can be locked in a semi-open state according to the intermediate locked position under the same principle as described above. It is also possible to freely adjust the opening amount of.

[Embodiment] Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. A switchgear according to the embodiment is made of resin for movably supporting an operating lever 6 as shown in FIG. Housing 1
And the first and second link members 7 and 8 which are connected between the housing 1 and the free end portion of the window glass G so as to extend and bend.
And the pivoting portions of the link members 7 and 8 and the operation lever 6
The side link glass is provided with a connecting link member 9 that connects the first link member 7 and the second link member 8 with the connecting link member 9 that links the And a roof glass such as a sunroof glass which opens and closes a window glass G rotatably supported by the vehicle body.

More specifically, the housing 1 for supporting the operation lever 6 is formed in a box shape having an opening 2 on the rear side half, and a panel 5 defining an opening edge of the vehicle body is provided with a screw member 5 interposed therebetween. The guide long groove 3 is formed in the longitudinal direction of the upper surface of the guide long groove 3, and a plurality of lock convex portions 4 are formed at both ends and an intermediate portion of the guide long groove 3 at regular intervals. Has become.

The operating lever 6 supported by the housing 1 is composed of a shaft portion 6a integrally having a fixing plate portion 6c and a knob portion 6b fixed to the shaft portion 6a, as shown in the drawing. With the fixed plate 6c positioned inside, hold the shaft 6a
Is supported in the guide long groove 3 of the housing 1 to freely reciprocate in the guide long groove 3, and
The shaft portion 6a can be elastically locked at each position of the lock projections 4.

Further, in this embodiment, the housing 1 and the window glass G
Of the two link members connected between the free ends, the first link member 7 has its one end 7a in the housing 1 through the shaft 10 in a state of protruding outward from the opening 2. For the second link member 8, which is pivotally pivotally mounted, a bracket 11 fixed to the free end of the window glass G is used.
On the other hand, one end portion 8a thereof is pivotally attached via a shaft 12, while the other end portions 7b and 8b of both link members 7 and 8 are pivotally attached to each other via a shaft 13.

Then, the other end 9a of the connecting link member 9 whose one end 9a side is fixed to the fixing plate 6c of the operation lever 6 is attached to the pivotally connecting portion between the other end portions 7b and 8b of both the link members 7 and 8. , Also axis 13
It is configured so as to be pivotally attached via.

Therefore, under the opening / closing device having such a configuration, as shown in FIG. 2, the operation lever 6 is temporarily moved to the guide long groove 3 of the housing 1.
When it is moved to the rightmost position in the inside and locked with the lock projection 4 at that position, the interlocking action of the connecting link member 9 corresponding thereto causes the first link member 7 and the second link member 8 to Since the pivotally connecting portion between the end portions 7b and 8b is bent into a horizontal V shape and automatically fits in the housing 1, the free end portion of the window glass G moves to the vehicle body side, and the window glass The blocked state of G is guaranteed.

On the contrary, when the lock projection 4 is unlocked, the operation lever 6 is moved to the opposite leftmost position in the guide long groove 3 of the housing 1 and locked with the lock projection 4 at that position, This time, as shown in FIG. 3, by the interlocking action of the connecting link member 9 in the opposite direction, the pivotally connecting portions of the first link member 7 and the second link member 8 are extended linearly, and the window glass G Since the free end portion is automatically moved to the outside of the vehicle, this ensures the fully opened state of the window glass G.

Moreover, in such a fully opened state, the locked state of the operation lever 6 is obtained, and the other end portion 9b of the connecting link member 9 has the pivotally connecting portions of the first link member 7 and the second link member 8 Since it is stretched in a straight line, there is no concern that the window glass G will accidentally move in the closing direction.

In the opening / closing device of this embodiment, when it is desired to adjust the opening amount of the window glass G, the operation lever 6 is moved to a desired position except the rightmost position or the leftmost position of the guide long groove 3. As shown in FIG. 4, if the locking projection 4 is engaged, the window glass G can be locked in a semi-open state according to the position of the locking projection 4 under the same principle as described above. As a result, the opening amount of the window glass G can be freely adjusted. Needless to say, such an operation can be performed from the fully opened state or the closed state.

Therefore, in this embodiment, the window glass G can be surely locked at the closed position and the fully open position by only moving the operation lever 6, but it can be surely locked at any half-open position. Since it becomes possible to lock, it is convenient for use, and the opening / closing operation of the window glass G is performed by simply moving the operation lever 6 linearly in the guide long groove 3 of the housing 1 and corresponding lock projection. Since it suffices to engage with the portion 4, the operability is greatly improved.

[Advantages of the Invention] As described above, the opening / closing device of the present invention can certainly lock the window glass in the closed position and the fully opened position by adopting the above-described configuration, but can also be used in any semi-opened position. Since it is possible to securely lock it, it is convenient for use, and when opening and closing the window glass, simply move the operation lever linearly with respect to the guide long groove of the housing to lock it in any position. Since it is good, the operability can be greatly improved.
