Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a window regulator for raising and lowering a window panel in an automobile, and particularly relates to an improvement of a wire-driven window regulator.

(2) Prior Art and Problems As this type of conventional window regulator, for example, those shown in FIGS. 1 to 3 are known. This is built into a door 1 of an automobile, and is a door inner panel 1a.
a guide rail 2 attached to the guide rail 2; a carrier plate 4 that is movably attached to the guide rail 2 and supports the window panel 3; It includes a wire 5 that is moved along the wire 5, and a drive device 6 that winds one end of the wire 5 and lets out the other end.

A downward flange 8 is formed on the waist portion 7 of the door inner panel 1a, and a guide rail 2 having a substantially U-shaped cross section with guide walls 2a and 2b formed on both sides has an upper end at the lower end of the flange 8. The door inner panel 1a is arranged in close proximity to each other.
It is fixed to via a bracket 9. The carrier plate 4 has a panel mounting surface 10 for fixing the window panel 3, and engagement grooves 11a and 11b that are formed protrudingly formed at the rear of the panel mounting surface 10 and slidably engage the guide walls 2a and 2b. The panel mounting surface 10 has support holes 12, 12 at both left and right ends for supporting the window panel 3.
The support member 14, which is fitted and fixed to the lower end of the window panel 3 via the protective rubber film 13, is fixed using bolts 15 and nuts 16. The carrier plate 4 is further formed with a locking hole 17 for locking the wire 5, and the divided ends of the two wires 5a and 5b are inserted into the locking hole through locking fittings 18a and 18b. 17 is locked. Then, one wire 5a goes upward from the split end and is passed around a perfect circular pulley 19 provided at the upper end of the guide rail 2, and then routed outward through the first guide part 20, and the other The wire 5b goes downward from the divided end, goes around the semicircular slide member 21 provided at the lower end of the guide rail 2, and then moves upward along the guide wall 2b to a position below the first guide part 20. The second guide part 2 provided in
It is routed outward through 2. These outwardly routed wires 5a and 5b are wound around the rotating drum of the drive device 6, and the handle 2
By operating the handle 23 in the opposite direction, the carrier plate 4 can be raised by winding one wire 5a and letting out the other wire 5b. It can be lowered (Jet-kai Show 58)
-Refer to Publication No. 17473).

By the way, although wire type window regulators generally have the advantage of being lighter than arm type and being able to reduce the thickness of the door 1, the amount of movement of the carrier plate 4 depends on the length of the guide rail 2 and the upper and lower ends. Since the upper end of the guide rail 2 is placed close to the lower end of the flange 8 of the door inner panel 1a as in the conventional example, This means that the length of the guide rail 2 is reduced accordingly. Therefore,
The carrier plate 4 can only rise to the maximum position below the flange 8 as shown by the imaginary line in FIG. In addition, the amount of overhang from the door waist portion 7 increases, which is disadvantageous.

In addition, rainwater, etc. leaking from the sealing surface of the weather strip 24 attached to the waist portion 7 flows through the flange 8 and drips onto the guide rail 2, rusting the guide rail 2 and the rotating shaft of the round pulley 19, and causing the window to become damaged. There was a problem that it adversely affected the operation of raising and lowering the panel 3.

(4) Purpose of the Invention The present invention has been made by focusing on the above-mentioned conventional problems, and its purpose is to increase the amount of movement of the carrier plate without complicating the structure, and to increase the amount of movement of the carrier plate without complicating the structure. To provide a window regulator capable of dealing with water leakage.

(5) Structure of the Invention In order to achieve the above object, the present invention includes a guide rail fixed to a door inner panel, a window panel moving member movably attached to the guide rail and supporting the window panel. A window regulator comprising a wire that is locked to the window panel moving member and moves the window panel moving member along the guide rail, and a drive device that winds up one end of the wire and lets out the other end. A box part is formed on the back side of the waist part of the door inner panel, and the upper end of the guide rail is fitted into the box part, and the window panel moving member is attached to the top of the guide rail. The gist is that a recess is formed into which the lower end of the waist of the door inner panel enters when it is moved.

(6) Embodiments of the invention Embodiments of the invention will be described below in detail based on the accompanying drawings.

In the first embodiment of the present invention shown in FIGS. 4 and 5, the waist portion 7 of the door inner panel 1a is
is provided with a downward flange 8 that is bent inward, and this flange 8 and the waist portion 7 form a box portion 25 on the back side of the waist portion. The guide rail 2 has a bracket 9a as before.
It is fixed to the door inner panel 1a through the
The height of the legs of the bracket 9a is lower than before, and the whole is closer to the door inner panel 1a than before, and the upper end of the guide rail 2 is fitted into the box part 25 to be close to the back surface of the waist part 7. It has been placed.

On the other hand, the carrier plate 26, which is attached movably along the guide rail 2, forms a window panel moving member together with the support member, and this carrier plate 26 is attached to the guide rail on the rear side of the panel mounting surface 27 as in the conventional case. 2 Engagement groove portion 28 that slidably engages with the guide walls 2a and 2b on both sides
