Description
Background of the Invention
The present relates to a window regulator for raising and lowering a window of a door of a motor vehicle.
Japanese Utility Model Publication 60-19896 discloses window regulator disposed between an inner panel of a door of a vehicle and a space for receiving a door glass, since a regulator handle for operating the regulator is provided on the inner panel. Accordingly, in order to provide such a space for the regulator, the inner door panel bulges into the interior space of the vehicle.
Moreover, a door trim pocket provided on the inner panel takes up the interior space, so that a leg room is decreased. Thus, interior space becomes confined, making passengers feel oppressed and uncomfortable while travelling on the vehicle.
Summary of the Invention
The object of the present invention is to provide a window regulator, whereby a sufficient interior space of the vehicle can be provided to ensure a comfortable travel on the vehicle.
According to the present invention, there is provided a window regulator for a door of a motor vehicle, the door having an outer panel, an inner panel, a glass receiving space provided between the outer and inner panels for receiving a glass, a window regulator device provided between the outer and inner panels, an operating member operatively connected to the window regulator device so as to raise and lower the glass.
The window regulator device comprises an endless wire connected to the glass and the operating member and disposed in a space between the outer panel and the glass receiving space. A part of the wire is extended into a space between the inner panel and the glass receiving space over a sash and engaged with the operating member, so that the glass is raised and lowered by the operation of the operating member.
In an aspect of the invention, the operating member is a regulator handle, and the wire is wound on a drum of the regulator handle.
The other objects and features of this invention will become understood from the following description with reference to the accompanying drawings .

Detailed Description of the Preferred Embodiment
Referring to FIGS. 1 and 3, each door 2 mounted on a body 1 of a two-door vehicle comprises a door sash 3, an outer panel 6 and an inner panel 7. A door glass 4 is mounted in the door 2 so as to slide along the door sash 3 and to be put in a glass receiving space 5 defined by the two panels 6 and 7, when lowered. A regulator device 8 for raising and lowering the glass 4 is disposed in an outer space 5a of the receiving space 5 between the glass 4 and the outer panel.
As shown in FIG. 2, the regulator device 8 comprises a vertical guide plate 8a having a pair of lobes 11 at which the guide plate 8a is fixed to a longitudinal reinforcement member 9 securely mounted on the inner side of the outer panel 6. The regulator device 8 further comprises pulleys 8b and 8c disposed on upper and lower portions of the guide plate 8a, respectively, endless operating wire engaged with the pulleys 8b, 8c, and connecting member 8f for connecting the wire 8d with a lower edge of the glass 4.
Referring to FIGS. 5 and 6, the connecting member 8f has upper and lower slides 13 and 14, right and left guide members 15 and 16, and a wire connector 17. The slides 13, 14 and guide members 15, 16 are slidably engaged with the guide plate 8a, for guiding the connecting member 8f. The wire 8d has a stopper 8g which is engaged with a hole of the wire connector 17, thereby connecting the wire with the connecting member 8f. The connecting member 8f is secured to the glass 4 by bolts 18.
As shown in FIG. 4, the wire 8d in a sheath 8e is lead around an upper part of a front portion 3a of the door sash (garnish) 3 to enter into an inner space 5b between the glass 4 and the inner panel 7. The wire 8d is wound on a drum 10a of a regulator handle 10 rotatably supported on the inner panel 7. The wire 8d is further arranged to go around the front portion 3c at a lower part, thereby returning to the outer space 5a.
When the regulator handle 10 is rotated, the wire 8d is moved in one direction so that the actuating member 8a is raised or lowered between the pulleys 8b and 8c. Hence, the door glass 4 is lifted so as to project out of the receiving space 5 or lowered to be inserted therein.
Since the regulator device 8 is disposed in the space 5a between the outer panel 6 and the glass 4 except for a small part of the wire 8d wound on the drum 10a, it is possible to minimize the space 5b. Therefore, the inner surface of the inner panel 7 according to the present invention can be caved in to a limit adjacent the inner surface of the glass 4, whereas in the conventional door, the surface of the panel is vertical as shown by a chain line 7a in FIG. 3. Accordingly, even if a door trim pocket is attached to the inner panel 7, the pocket does not largely take up the space in the vehicle. Thus, passengers do not feel oppressed and are able to travel comfortably.
In addition, since the space 5b is vacant, the space can be further utilized for receiving other things, for example, a wire harness can be easily disposed therein. Since the regulator device 8 is disposed along the outer panel 6, the rigidity thereof is improved.
While the presently preferred embodiment of the present invention has been shown and described, it is to be understood that this disclosure is for the purpose of illustration and that various changes and modifications may be made without departing from the scope of the invention as set forth in the appended claims.
Claims
What is claimed is:
1. A window regulator for a door of a motor vehicle, the door having an outer panel, an inner panel, a glass receiving space provided between the outer and inner panels for receiving a glass, a window regulator device provided between the outer and inner panels, an operating member operatively connected to the window regulator device so as to raise and lower the glass, the improvement comprising: the window regulator device having an endless wire connected to the glass by a connecting member and engaged with the operating member, and disposed in a space between the outer panel and the glass receiving space, a part of the wire being extended into a space between the inner panel and the glass receiving space over a sash and engaged with the operating member, so that the glass is raised and lowered by the operation of the operating member.
