Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door glass lifting device provided on a door of a vehicle such as an automobile.
[0002]
[Prior art]
Generally, a door of an automobile includes a door glass lifting device for raising and lowering the door glass. For example, as described in JP-A-10-102902 (Prior Art 1), a door glass is slidably supported by front and rear sashes, and a carrier plate is locked to a pair of front and rear wire rope moving parts. The door glass raising / lowering apparatus which supports the front part and rear part of a door glass with each carrier plate is proposed.
[0003]
Alternatively, as described in Japanese Patent Application Laid-Open No. 11-44151 (Prior Art 2), the front and rear portions of the door glass are supported by a pair of front and rear glass support members locked to a pair of front and rear wire rope moving portions. There has also been proposed a door glass elevating apparatus that elevates and lowers the door glass along a pair of front and rear guide rails extending in the vertical direction.
[0004]
[Problems to be solved by the invention]
In the prior art door glass lifting device, the front and rear carrier plates can independently rotate about the axis of the wire before the door glass is assembled to the pair of front and rear carrier plates. In addition to being able to move relatively freely in the direction and the door depth direction, the glass tends to tilt in the vertical direction in a side view of the glass. In order to assemble the glass to the front and rear carrier plates in this unstable state, the operator must assemble the position and posture of one carrier plate so that it matches the glass, and then assemble the other carrier plate in the same way. There is a drawback in that it takes time to assemble.
[0005]
On the other hand, in the door glass lifting device of the prior art 2, when the glass moves up and down along the guide member extending in the vertical direction, the front edge and the rear edge of the glass move in the vertical direction along the front and rear sashes of the door. Therefore, if the accuracy of the parallelism between the guide member and the sash is not good, not only the raising and lowering operation of the glass becomes smooth, but excessive stress acts on the glass, which is not preferable. In addition, since two fairly long guide members are required, the number of parts is not only large, but it is disadvantageous in reducing the weight.
[0006]
Accordingly, an object of the present invention is to provide a door glass elevating device that is simple in construction and easy to assemble.
[0007]
[Means for Solving the Problems]
The door glass elevating device according to claim 1 for achieving the above object includes a door glass that moves up and down along a sash provided in front and rear of the door, and extends in the front-rear direction of the door glass and at a lower end portion of the door glass. A pair of front and rear glass fixings having a carrier plate that is attached and has locking portions at two front and rear portions, and screw members that are respectively provided at both ends of the carrier plate and are inserted into mounting holes formed in the door glass. And a linear body that has a pair of front and rear moving parts fixed to the respective locking parts and that is driven in a direction in which the moving parts move up and down the door glass in synchronization with each other, the carrier plate is under the door glass is formed into a hook-shape facing up by cutting and raising a part of the carrier plate between the pair of glass fixing portion Longitudinal direction intermediate portion has a glass support portion having a shape which supports from below the said door glass the glass supporting portion as a fulcrum is capable of moving in the vertical direction, and the glass of the carrier plate A part of the carrier plate is cut and raised between the support part and the glass fixing part to form a hook shape facing upward, and a lower end of the door glass is inserted, and a gap is formed between the lower end of the door glass. An auxiliary support portion to be formed is provided, and by making the size of the mounting hole larger than the outer diameter of the shaft portion of the screw member, the door glass is moved vertically with respect to the carrier plate with the glass support portion as a fulcrum. The relative movement is possible. This door glass lifting device is supported by a carrier plate having a lower end portion of the door glass extending in the front-rear direction, and a sash in which the door glass is provided at the front and rear of the door by moving the front and rear moving parts of the rope body by a motor or the like. It moves up and down while being guided by. The carrier plate is attached to the front moving part and the rear moving part of the cable body in a stable state by a pair of front and rear locking parts provided at predetermined positions, and the door glass can be easily assembled to the carrier plate. .
[0008]
In the door glass lifting apparatus according to claim 2, in order to adjust the attitude of the glass, the door glass is raised toward the upper sash before the screw member of the glass fixing portion is tightened. Since this door glass can tilt up and down along the glass surface with the glass support part of the carrier plate as a fulcrum, when the upper edge of the door glass is pressed against the upper sash, the entire upper edge of the door glass is The posture is automatically adjusted so that it contacts the upper sash evenly. By tightening the screw member in this state, the door glass is fixed in a normal posture with respect to the sash and the carrier plate. In this case, if the glass support portion is below the center of gravity of the door glass, the door glass can easily tilt with the glass support portion as a fulcrum during the posture adjustment, and the posture adjustment can be easily performed.

The rear edge portion 70d of the door glass 70 is in contact with the weather strip 101 provided on the rear sash 42 of the door module 12 so as to be slidable in the vertical direction. That is, the door glass 70 moves up and down while being guided by the pair of front and rear sashes 41 and 42 while maintaining a close contact state with the weather strips 100 and 101 as the carrier plate 71 moves up and down. .
[0026]
Below, the procedure which fixes the door glass 70 to the carrier plate 71 is demonstrated.
By inserting the lower end portion 70 b of the door glass 70 into the glass support portion 74 and the auxiliary support portions 79 and 80, the lower end 70 e of the door glass 70 is supported by the bottom surface 74 a of the glass support portion 74. At this time, the screw member 75 and the nut 85 of the glass fixing portions 77 and 78 are not tightened, and the door glass 70 is allowed to move to some extent in the vertical direction with respect to the carrier plate 71. Then, the motor 65 is rotated in the direction in which the door glass 70 is raised, and the door glass 70 is fully raised toward the upper sash 43.
[0027]
By doing so, the upper edge 70 a of the door glass 70 comes into contact with the upper sash 43. Since the screw members 75 of the glass fixing portions 77 and 78 are loosened at this time, the door glass 70 can move up and down along the glass surface with the glass support portion 74 as a fulcrum. When the edge 70a is pressed against the upper sash 43, the posture of the door glass 70 (inclination in the vertical direction along the glass surface) is automatically set so that the entire upper edge 70a of the door glass 70 contacts the upper sash 43 without any gap. Adjusted.
[0028]
In this state, that is, in a state where the attitude of the door glass 70 is adjusted, the door glass 70 is fixed to the carrier plate 71 by tightening the nut 85 to each screw member 75 in the glass fixing portions 77 and 78. After fixing the door glass 70 to the carrier plate 71 in this way, even if the door glass 70 is lowered, the posture of the door glass 70 is maintained in the correct state after adjustment, and the door glass 70 can be raised again to the fully closed position. In this case, the upper edge 70a of the door glass 70 can come into contact with the upper sash 43 evenly without any gap.
[0029]
In addition, the shape which supports the lower end 70e of the door glass 70 from the lower side may be sufficient as the glass support part 74 like 2nd Embodiment of the carrier plate 71 shown in FIG. Further, in carrying out the present invention, each element constituting the present invention is appropriately modified, such as a door glass and a carrier plate, a glass support portion, a glass fixing portion, a mounting hole, a cable body, and a sash. Needless to say, it can be implemented.
[0030]
【The invention's effect】
According to the door glass raising / lowering apparatus described in claim 1, the workability when assembling the glass to the carrier plate is improved, and it is possible to make it difficult to cause a problem that the glass is inclined in the vertical direction in a side view of the glass. In addition, since the sash before and after the door also functions to guide the raising and lowering of the glass, it can be configured to be lighter than those using a separate guide rail or the like, can be easily assembled, and the number of parts can be reduced. And in this invention, since each moving part of a cable body is mutually connected by the integral carrier plate extended in the front-back direction, even if the cable body which becomes easy to become unstable is used, a door glass can be stabilized via a carrier plate. It can be supported, and the carrier plate is also prevented from rotating around the axis of the cable body.
According to the second aspect of the present invention, it is possible to easily and quickly perform the posture adjustment operation of the glass with respect to the sash of the door, and the glass can be assembled in a normal posture.
