DETAILED DESCRIPTION OF THE INVENTION

[0013] The invention provides an adjustable glass gripping device for a vehicle window regulator. As shown in FIG. 1, the window regulator includes a rail 100, glass gripping devices 500 and a driving device 900. A glass window (not shown) is held by the glass gripping devices 500. The driving device 900 drives the glass gripping devices 500 to elevate or lower on the rail 100 through a linking element 1. The linking elements 1 may be cables as shown in the figure. The cables parallel the rail 100 and connect the driving device 900 so that the driving device 900 can move the cables and the glass gripping devices 500 along the rail 100. As a result, the glass window held by the glass gripping devices 500 can be raised or lowered.

[0014] As shown in FIGS. 2-4, the glass gripping device 500 includes a glass gripper 5, a limiter 6 and an adjusting bolt 7.

[0015] The glass gripper 5 is slidably connected on the rail 100 and no specific structure is required. As an example, the embodiment includes a base 51, and preferably further includes a fastener 52 and a reinforcement element 53.

[0016] The fastener 52 has a gripping slot 521 for gripping a window glass and two opposite sides for being separately attached by the base 51 and the reinforcement element 53. Preferably, a fixer 54 is used to secure the fastener 52 between the base 51 and the reinforcement element 53.

[0017] The base 51 has two screwing portions 511. In this embodiment, the base 51 is formed with two walls and each of the walls is provided with one screwing portion 511. A receiving room 512 is formed between the two screwing portions 511 of the base 51. The receiving room 512 is defined by inner walls of the base 51, and the abovementioned walls are two of these inner walls.

[0018] The limiter 6 is secured on the linking element 1 and is located at the base 51. As an example, in this embodiment, the limiter 6 is located in the receiving room 512 so as to limit the limiter 6 with the inner walls. In detail, the limiter 6 has a pivoting portion 61 and a fixing portion 62 for fastening the linking element 1. The fixing portion 62 may be a holding slot to fasten the linking element 1. The limiter 6 can be moved along with the linking element 1.

[0019] The adjusting bolt 7 has two threaded portions 71 and a limited portion 72 therebetween. The limited portion 72 may be any non-threaded shape. In the shown embodiment, the limited portion 72 is a smooth rod whose diameter is less than those of the two threaded portions 71.

[0020] The two threaded portions 71 are separately screwed into the screwing portions 511 of the base 51 so as to make the limited portion 72 located in the receiving room 512 or between the two screwing portions 511. Also, the pivoting portion 61 of the limiter 6 pivots on the limited portion 72 so as to make the adjusting bolt 7 limited by the limited portion 72 rotate in the pivoting portion 61. As shown in FIGS. 3 and 4, the limiter 6 is equivalently attached between the two threaded portions 71 for position limiting.

[0021] As a result, the limiter 6 can be moved along with the linking element 1, and the limiter 6 can lead the glass gripper 5 to move together through the adjusting bolt 7. Finally, the glass gripper 5 can move along the rail 100.

[0022] The glass gripper has a limited portion. The limiter is assembled to correspond to the limited portion for limiting a position of the adjusting bolt.

[0023] As shown in FIGS. 4 and 5, to allow the limiter 6 to make to-and-fro adjustments, the limiter 6 is not in contact with the inner walls of the receiving room 512 in its to-and-fro direction. In detail, two distances D1, D2 are separately kept between two opposite ends of the limiter 6 and their respective adjacent inner walls, so that the limiter 6 can be moved to touch an inner wall in a direction or the other inner wall in an opposite direction. In other words, the distances D1, D2 are the maximum adjustable length of the limiter 6.

[0024] As shown in FIG. 6, when a window glass in held by the glass gripper 5 and the window glass is oblique, the glass gripper 5 can be moved downward along the rail 100 (the arrow in FIG. 6) by rotating the adjusting bolt 7 (the adjusting bolt 7 cannot move in all directions except its axial direction because it is limited). That is, the distance D1 (FIG. 4) is shortened so that an unintended high end of the window glass can be lowered. The window glass can be continuously adjusted until one end of the limiter 6 is stopped by an inner wall.

[0025] As shown in FIG. 7, when one side of the window glass is too low, the glass gripper 5 can be moved upward along the rail 100 (the arrow in FIG. 7) by reversely rotating the adjusting bolt 7. That is, the distance D2 (FIG. 4) is shortened so that an unintended low end of the window glass can be raised. The window glass can be continuously adjusted until the other end of the limiter 6 is stopped by the other inner wall.

[0026] As shown in FIG. 4, the adjusting bolt 7 may have an adjusting portion 73 which is any structure allowing the adjusting bolt 7 to rotate. As an example, in the shown embodiment, the adjusting portion 73 is an inner hexagonal hole, so that the adjusting bolt 7 can be rotated by a hexagonal wrench.

[0027] Please refer to FIG. 1, the glass gripping device 500 of the invention can be installed in a car door to control a window glass to raise or lower and allow the window glass to be fine-tuned for completely matching a window frame if it is oblique.

[0028] In sum, in the invention, the adjusting bolt 7 is screwed into the glass gripper 5, the glass gripper 7 is limited by the limiter 6 and the limiter 6 is driven by the linking element 1 and limited in the receiving room 512 of the glass gripper 5. As a result, every glass gripping device 500 can be independently adjusted, and the window glass can be adjusted by rotating the adjusting bolt 7. It is very time and labor saving.

[0029] The invention can be used in any vehicle door, and especially those without a window frame. Because a window glass in such a vehicle door cannot be positioned by a window frame rather than a body, incomplete matches tend to occur. By the invention, complete match between the window glass and the body can be guaranteed.

[0030] It will be appreciated by persons skilled in the art that the above embodiment has been described by way of example only and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
