Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stopper structure for restricting a rise of a door glass in a vehicle door, particularly a sashless door, at a most raised position of the door glass.

(Prior Art) As a door glass stopper structure provided in a conventional sashless door, for example, one described in Japanese Utility Model Laid-Open No. 62-43012 is known.

This conventional structure has a guide rail inside the door,
A guide roller slidably provided on the guide rail is attached to a door glass, the door glass is connected to an elevating position, and is engaged at an ascending position of the door glass to restrict the ascending of the door glass to a door side stopper. And the glass side stopper was provided. Both stoppers were attached at positions apart from the guide rail.

Therefore, when the elevating device is operated, the door glass moves up and down while being guided by the guide rollers sliding on the guide rails, and its rising position is restricted by the engagement of both stoppers. By preventing the shake in the (vehicle width) direction with the stabilizer, the engagement of both stoppers is ensured.

(Problems to be Solved by the Invention) However, in the conventional stopper structure, since the mounting positions of both stoppers are positions separated from the guide rail in the front-rear direction, there are the following problems.

When the rise of the door glass is restricted, the roller may be twisted, and the roller, the roller support shaft, and the guide rail may be deformed.

As the distance from the position supported by the guide rail increases, the amount of deformation (deflection) of the door glass due to the lifting force of the lifting device increases, so that the amount of shake of the door glass with respect to the door increases. For this reason, in order to ensure the engagement of both stoppers, it is necessary to secure a large margin for engagement of both stoppers, and both stoppers become large. Further, the distance between the door glass and the door panel becomes wide, and the door glass easily shakes with respect to the door.

When the door glass is deformed while the door glass is being lifted, the glass-side stopper may interfere with other components inside the door, such as the lifting device, the wiring, the speaker, the motor, and the guard bar.

Since the present invention has been made to solve the above-mentioned problems, the purpose thereof is to prevent the roller from being twisted when the door glass is restricted from rising.
As a result, it is possible to prevent deformation of the roller, the roller support shaft, and the guide rail, and to ensure that the glass-side stopper and the door-side stopper can be securely engaged with each other even when the margin for engagement is reduced. Accordingly, it is an object of the present invention to provide a door glass stopper structure capable of reducing the size of both stoppers and preventing interference with other components in the glass-side stopper-side door.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, a door glass is provided in a door so that the door glass can be moved up and down by an elevating device, and inside the door, a guide rail for guiding the up and down movement of the door glass. Is extended and fixed in the up-and-down direction of the door glass, and a guide roller that slides in the groove of the guide rail is attached to the door glass, and the rise of the door glass is restricted at the highest position of the door glass. A door-side stopper and a glass-side stopper are provided, the door-side stopper is fixed to the door on the guide rail extending direction line including on the guide rail, and the glass-side stopper is arranged at a position near the guide roller. The locking piece of the glass-side stopper, which is attached to the door glass and engages with the locking piece of the door-side stopper, is placed in the groove of the guide rail. The means is arranged so as to enter.

(Operation) In the present invention, when the elevating device is operated, the door glass is moved up and down while being guided by the guide rail by the guide roller sliding in the groove of the guide rail. At this time, the locking piece of the glass-side stopper moves in the groove of the guide rail.

Then, the door glass is restricted from rising when the glass side stopper is engaged with the door side stopper at the highest position.

When the door glass is restricted from rising, both stoppers engage with each other on the extending direction line of the guide rail, so that the guide roller is not twisted.

Further, in the present invention, the glass-side stopper is arranged near the upper part of the guide roller, and at this position, since the amount of deformation of the door glass due to the pushing force of the lifting device is small, the shake of the door glass with respect to the door is small. . Therefore, the engagement allowance of both stoppers can be reduced.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view showing an essential part of a stopper structure for a door glass according to an embodiment of the present invention, wherein 1 is a door. This door 1 is formed into a sashless type as shown in FIG. 2, and as shown in FIG. 1, an outer door panel 11 and an inner door panel 12 have an internal space 13 between them.
Are joined together at their peripheral portions so as to form a door slit 14 for raising and lowering the door glass, which opens the internal space 13 at the upper edge, and the weather strip 1 is formed in this door slit 14.
5,16 are attached.

The door 1 is provided with a door glass 2 which can move in and out through the door slit 14. And the internal space
An X-arm type lifting device 5 for lifting the door glass 2 is provided at 13.

The raising and lowering of the door glass 2 is guided by the guide rails 3, 3 and the guide rollers 4, 4.

That is, the guide rollers 4, 4 are attached to the lower end of the door glass 2 at both ends in the vehicle front-rear direction by the support shafts 41, respectively.

On the other hand, the guide rails 3, 3 extend in the vertical direction in the internal space 13 and are fixed to the inner door panel 12, and the guide roller 4 is formed in a rollable groove 31, and the support shaft The rail 41 is formed of a member having a cross-sectional shape in which a rail slit 32 opened to the outer door panel 11 side is formed so as to be movable in the vertical direction.

A door side stopper 6 and a glass side stopper 7 are provided between the door glass 2 and the inner door panel 12.

That is, the both stoppers 6 and 7 restrict the rise of the door glass 2 at the most raised position of the door glass 2, and the door side stopper 6 is formed in a substantially L shape, and one piece is a mounting piece 61.
, The other locking piece 62 is attached to the inner door panel 12 with a screw 63 so as to project into the door slit 14, and in this case, the door side stopper 6 has the extension direction line C of the guide rail 3 (second (See the figure). The door-side stopper 6 may be attached to the upper end portion of the guide rail 3, while the glass-side stopper 7 is in contact with the surface of the lower end portion of the door glass 2 on the vehicle interior side, as shown in FIG. At the lower end of the mounting portion 71, an engaging portion 72 that is hooked on the lower edge of the door glass 2 is bent outward, and this engaging portion is further formed.
72 is covered with a coating portion 73 made of vinyl chloride, and a locking piece 74 is formed by bending inward at the upper end of the mounting portion 71.

The glass-side stopper 7 is fastened together with the support shaft 41 of the guide roller 4 and attached to the door glass 2. In this case, the locking piece 74 is located near the guide roller 4 and near the guide rail 3. Is arranged so as to be positioned on the extending direction line C of the guide rail 3, and as shown in FIG. 4, the tip end of the locking piece 74 enters the groove 31 from the rail slit 32 of the guide rail 3 in the mounted state. The rail slit 32 is arranged so as to be movable when moving up and down.

Next, the operation of this embodiment will be described.

When the lifting device 5 is activated, the door glass 2 is guided by the guide roller.
4 and 4 are moved up and down while being guided by sliding in the grooves 31 and 31 of the guide rails 3 and 3, and the locking piece 74 of the glass side stopper 7 is the locking piece of the door side stopper 6 at the highest position. By engaging 62, the rise will be restricted.

Since the stoppers 6 and 7 are provided on the extending direction line C of the guide roller 3 in the rising restriction state by the stoppers 6 and 7, the engagement position of the stoppers 6 and 7 and the guide roller 4 are There is no offset amount in the front-rear direction of the vehicle,
No twist acts on the guide roller 4.

Therefore, it is possible to obtain an effect that the guide roller 4 and the guide rail 3 are not likely to be deformed when the ascent is restricted.

The movement of the door glass 2 on which the guide roller 4 is attached is restricted by the guide rails 3 in the vehicle width direction, and the amount of deformation due to the pushing force of the lifting device 5 is small. This is the part with the least horizontal deflection. Therefore, even with the glass-side stopper 7 attached near the upper portion of the guide roller 4, the shake in the vehicle width direction is small, and therefore both stoppers 6,
Even if the engagement allowance of 7 is reduced, the engagement is ensured.

In this way, since reliable engagement can be obtained even if the engagement margin of both stoppers 6 and 7 is reduced, there is an effect that both stoppers 6 and 7 can be made compact. Even if the gap between the door 2 and the door side stopper 6 is made smaller than the conventional one, they do not hit each other, and as a result, the effect that the door slit 14 can be made narrower and the weather slip 16 can be made smaller to reduce the cost can be obtained. To be

Further, since the tip end member of the locking piece 74 of the glass side stopper 7 is inserted into the groove 31 of the guide rail 3, the door glass 2 is brought closer to the guide rail 3 side and the engagement allowance of both stoppers 6, 7 is predetermined. It is possible to reduce the protrusion amount of the locking piece 62 of the door-side stopper 6 while ensuring the above, and thus it is possible to prevent interference between the door-side stopper 6 and the door glass 2.

Further, as described above, since the glass-side stopper 7 moves in the guide rail 3, it is possible to prevent the glass-side stopper 7 from interfering with the elevating device 5 and other motors, wirings, speakers, etc., which are not shown, An effect that the certainty of operation and safety are improved can be obtained.

Further, in the embodiment, since the glass side stopper 7 is fastened together with the guide roller 4 and fixed to the support shaft 41, an effect that the mounting workability is improved can be obtained.

The specific structure is not limited to the above-mentioned embodiment, and for example, an elevating guide mechanism including a guide rail and a guide roller may be provided at two or more places, and the stopper mechanism of the present invention has an elevating guide mechanism at one place. It may be provided for the mechanism and combined with another stopper mechanism.

Further, the glass-side stopper can be independently attached by screwing or bonding, instead of being fastened together with the support shaft of the guide roller.

(Effect of the Invention) As described above, according to the present invention, when the door glass is restricted from rising, both stoppers engage with each other on the extending direction line of the guide rail, so that the guide roller is twisted. As a result, the effect that the guide roller, the support shaft of the roller, and the guide rail are not deformed by this twist is obtained.

Further, since the glass-side stopper is arranged at a position where the swinging with respect to the door is small in the door glass so that the engagement margin of both stoppers can be reduced, both stoppers can be made compact and the structure can be simplified. In addition, the cost can be reduced, and the interference between the door-side stopper and the door glass can be prevented.

Furthermore, the glass side stopper moves on the guide rail,
Moreover, since the locking piece of the glass-side stopper moves in the groove of the guide rail, the glass-side stopper is used for other parts in the door, such as the lifting device, wiring, speaker, motor,
The effect of not interfering with the guard bar or the like is obtained.
