Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window regulator for raising and lowering a windshield of an automobile.

Generally, as shown in FIG. 1, a wire-type window regulator 1 is constructed by sliding a slider plate 4 driven by a wire 3 along a guide rail 2 fixed to a door panel or a vehicle body panel (not shown). A window glass 5 fixed to the slider plate 4 is raised and lowered. D is a drum that drives the wire 3. When the drum D is rotated manually or by a motor, one end of the wire 3 is wound around the drum D and the other end is rewound, so that the wire 3 is rotated by the drum D. Move up and down between 2 guide rails! ! I will be treated.

By the way, as shown in FIG. 2, the conventional guide rail 2 has vertical walls 6 and 7 that are substantially perpendicular to the panel by bending both sides of a strip-shaped steel plate into a substantially U-shape, and one of the vertical wall 7
A panel is used in which the panel is bent outward to form a parallel wall 8 that is substantially parallel to the panel, and the other vertical wall 6 and the parallel wall 8 are used as engaging portions. A pair of legs 9 and 10 are provided protruding from the slider plate 4, and each of the legs 9 and 10 has a vertical wall 62 serving as the retaining portion.
and a sliding groove 9a into which the parallel walls 8 are slidably fitted.

tOa is formed. Therefore, the slider plate 40 is prevented from swinging in the longitudinal direction of the vehicle by the vertical wall 6 and the sliding groove #9a that fits this, and the parallel wall 8 and the sliding groove tO that fits this.
At point a, the slider plate 40 is designed to prevent the vehicle from swinging in the left-right direction.

A plate spring 11 is interposed between the parallel wall 8 and the sliding groove tOa to reliably prevent the slider plate, that is, the windshield 50 from swinging in the left and right directions 1- of the vehicle. be.

However, such conventional window regulator IV
In C, the vertical wall 6 and parallel wall 8 constituting the retaining portion of the guide rail 2 had a single-layer structure using both ends of the strip steel plate. Therefore, in order for the vertical wall 46 and the parallel wall 8 to have the strength necessary to hold the slider plate 4, it is necessary to increase the thickness of the strip steel plate forming the guide rail 2.

As another conventional example, as shown in FIG. 3, one vertical wall 61 of a pair of retaining portions formed on the guide rail 2
There is one that has a two-layer structure by bending the L. In this case, the vertical wall 6a has a two-layer structure, which improves its strength.
The other parallel wall 8 has a one-piece structure, and in order to maintain the strength of this parallel wall 8, the plate thickness of the guide rail 2 becomes thick. For this reason, there are problems in that the cost increases and the weight of the guide rail 2 increases, making it impossible to reduce the weight of the vehicle.

In view of such conventional problems, the present invention has a two-piece structure by bending a pair of engaging parts formed on both sides of a guide rail into a substantially U-shape, thereby increasing the strength of the retaining part. It is an object of the present invention to provide a window regulator in which the plate thickness of the guide rail can be reduced by improving the thickness of the guide rail.

That is, FIG. 4 shows a guide rail 1 showing an embodiment of the present invention.
00, the guide rail 100 is formed by bending a strip steel plate, and has a vertical wall 110 on one side as a holding part and a parallel wall on the other side as an engaging part. 120 is formed. The vertical wall 110 is bent into a U-shape such that the opposing pieces 111 and 112 are perpendicular to a panel (not shown).
It has a two-layer structure with 11 and 112. Historically, the parallel wall 120 is bent along the middle part 101 of the guide rail 100, then perpendicularly to a panel (not shown), and the tip thereof is bent outward again. It is formed into a U-shape, and both pieces 121 and 122 are arranged parallel to the panel. Therefore, the parallel wall 120
Even in this case, the two pieces 121 and 122 have a two-piece structure.

Reference numeral 130 denotes a slider plate, and the slider plate 130 has a pair of first legs 140. which are slidably fitted into the vertical wall 110 and parallel wall 120 of the guide rail 100. A second leg 150 is provided.

The first leg portion 140 is formed with a slide M*141 that fits on the outside of the U-shaped vertical wall 110, and when the vertical wall 110 is fitted into this sliding groove 141, the slider plate 130 It is designed to prevent the vehicle from swinging in the longitudinal direction. On the other hand, the second leg part 150 is formed by cutting and forming the slider plate 130 as shown in FIG.
A support protrusion 160 formed in a letter shape, and this support protrusion 160
The shoe 170 is made of an elastic material such as synthetic resin or rubber and is fitted onto the tip 161 of the shoe 170. The shoe 170 includes a pair of hollow sliding portions 171 facing each other in the length direction of the guide rail 100 and having a diamond-shaped cross section;
172 and these pair of hollow sliding parts 171 and 17
2 and a connecting portion 173 that connects the connecting portion 173.
The mounting hole 174 formed in this way is adapted to fit into the tip 161 of the support protrusion 160. Then, the hollow sliding parts 171 and 172 of the shoes 170 are connected to both 121 forming the parallel walls 120 of the guide rail 100,
122, the shoe 170 prevents the slider plate 1300 from swinging in the left-right direction of the vehicle. At this time, the elastic force of the hollow sliding parts 171 and 172 prevents rattling between the second leg part 150 and the parallel wall 120, and ensures that the slider plate 130 swings the windshield in the left-right direction of the vehicle. is prevented. Therefore, the leaf spring that was conventionally provided in this part becomes unnecessary.

With the above configuration, the guide rail 100 used in the window regulator of the present invention has a slider plate 13
1st of 0. A vertical wall 110 and a parallel wall 120 as engaging parts that fit into the second legs 140 and 150 are connected to both pieces 1.

, 121, 122, the first. 2nd leg] 4 to 150
Since it is possible to slidably hold the retaining portion, it is possible to improve the strength of the retaining portion. Therefore, the guide rail 100
For example, the conventional guide rail 2 structure used a thickness of 1.6 mm, but the present invention uses a thickness of 1.0 to 1.2 mm. But you can get enough strength. In addition, in the case of a satsuri-less type such as a hard top car, it is better to make the plate thickness 1.4 mm because the guide rail 100 bears most of the load due to the swinging of the windshield. good. Even in this case, the thickness can be made thinner than in the conventional case.

6 and 7 show other embodiments in which the shape of the shoe 170a of the second leg portion 150a is different. That is, the shoe 170 according to the embodiment shown in FIGS. 4 and 5 has a pair of hollow sliding parts 171 and 172 formed in a diamond-shaped cross section, and a hollow part S extending in both directions of the guide rail 100. However, this embodiment differs from this in that one hollow sliding part 175 is formed with a rectangular cross section, and a hollow part S extending in the length direction of the guide rail 100 is formed.
′ is formed.

In this embodiment, the support projection 160a erected from the slider plate 130 is formed in a straight shape, and the mounting hole 177 formed in the mounting portion 176 of the shoe 170a is inserted from above the support projection 160a. It is designed to be fixed. In this embodiment, as in the previous embodiment, the resilient force of the shoe 170a itself makes it possible to eliminate the conventionally used leaf spring.

Furthermore, in each of the embodiments described above, the second leg portion 150
, Since the shoes 170°170a formed of an elastic member were used for the tsoa, the shoes 170, 170
The flexible action acting on the hollow sliding parts 171, 172, 175 and the forming bases of the hollow sliding parts 171, 172, 175 can absorb assembly errors.

As explained above, in the present invention, the pair of legs of the slider plate fixed to the windshield is slidably fitted and held in the pair of aging retaining parts of the guide rail, and In the window regulator in which the window glass is raised and lowered by sliding the slider plate along the guide rail, a pair of engaging portions of the front guide rail are each bent into a substantially U-shape,
Since the leg portions of the slide plate are held by both the U-shaped bent portions, the engaging portion has a two-piece structure, and the strength of the retaining portion can be improved. Therefore, it is possible to reduce the thickness of the guide rail, thereby achieving excellent effects such as reducing costs from the material standpoint and reducing the weight of the vehicle.
