Description

[Detailed description of the invention] (Field of industrial application) This invention connects the window glass via a carriage to a geared cable guided by a tube-shaped guide whose at least part is disposed in the direction of the elevation of the window glass. The present invention also relates to a window regulator that raises and lowers the window glass by reciprocating the geared cable.

(Prior Art) Examples of this type of wind regulator include those shown in FIGS. 4 to 8, for example. In these figures, inside the tube-shaped guide 2, at least a part of which is disposed in the vertical direction of the window glass 1,
A geared cable 3 formed by winding a wire into a coil around a core wire is inserted and arranged. The geared cable 3 meshes with a gear (not shown) in a feeding device 4 that rotates electrically or manually, and reciprocates within the geared cable 3. As shown in FIG. 5, the guide 2 has a slit 2a formed in the vertical direction toward the window glass 1, and the window glass is inserted through a carriage 5 movably inserted into the slit 2a. A glass holder 6 attached to the lower edge of the window glass 1 is connected to a geared cable 3, and the reciprocating movement of the geared cable 3 moves the window glass 1 up and down.

By the way, in the wind regulator, if there is a gap between the cable fixing part of the carriage 5 and the inner surface of the guide 2, the carriage 5 will collide with the guide 2 due to vibrations when the car is running, causing abnormal noise. Occur. In order to solve this problem, for example, Japanese Patent Publication No. 60-34671 proposes that the spacer 7 be locked to the carriage 5 so as to eliminate the gap between the outer surface of the carriage 5 and the inner surface of the guide 2. There is. This will be explained with reference to FIGS. 5 to 8. In this conventional example, the carriage 5 has a fastening part 5a which is fastened to the glass holder 6 by a bolt, and a protrusion part 5b which is formed to protrude in the direction of the geared cable 3 through the slit 2a in a direction perpendicular to the fastening part. , and a cylindrical cable fixing part 5c formed from the base end of the protruding part. Caulking pieces 5d are formed by notches at the upper and lower ends of the fixing portion 5c, and the carriage 5 is fixed to the geared cable 3 by caulking the caulking pieces 5d.

As shown in FIG. 8, the spacer 7 has a substantially cylindrical shape and has a slit 7a in the generatrix direction, and protrusions 7b are formed protruding from both ends of the slit 7a. This spacer 7 wraps around the cable fixing portion 5c of the carriage 5.
The projection 7b projects outward through the slit 2a of the guide 2, and the projection 5b of the carriage 5 abuts the upper and lower end surfaces. Therefore, the spacer 7 moves together with the carriage 5 and is always interposed between the outer surface of the cable fixing portion 5c of the carriage 5 and the inner surface of the guide 2. Therefore, due to the action of the spacer 7, the carriage 5 that occurs due to vibrations when the car is running is
It is possible to prevent abnormal noise from occurring due to collision between the guide 2 and the guide 2.

(Problem that the invention attempts to solve) By the way, in the above wind regulator,
Since the spacer is disposed outside the cable fixing portion, the thickness of the cylindrical portion of the spacer is reduced.
For this reason, the conventional device described above has a problem in that it is difficult to mold the spacer.

This idea was created in view of the above problems.
The purpose is to realize a wind regulator which uses a spacer that is easy to mold and attach, and which can prevent abnormal noises caused by collisions between the carriage and the guide caused by vibrations when the vehicle is running.

(Means for Solving the Problems) The present invention for solving the above problems is such that a geared cable is guided by a tube-shaped guide, at least a part of which is disposed in the direction of elevation of the window glass, and a geared cable is provided in the guide. In a window regulator, the geared cable inside the guide and the window glass outside the guide are connected through a carriage passing through a slit, and the window glass is raised and lowered by reciprocating the geared cable. ,
A cylindrical outer surface is in sliding contact with the inner surface of the guide, a protrusion is formed on the cylindrical outer surface to fit into the slit, and a groove that can be engaged with the geared cable is threaded on the cylindrical inner surface. The present invention is characterized in that a cylindrical synthetic resin spacer is engaged with a portion of the geared cable near the carriage.

(Function) In the wind regulator of the present invention, the spacer that slides on the inner surface of the guide is attached to the geared cable near the carriage.
The carriage is restricted from moving in the circumferential direction of the guide.

(Example) Hereinafter, an example of the present invention will be described in detail using FIG. 1 and FIG. 2. In these figures, the same parts as in Figs. 4 to 8 are designated by the same reference numerals.
The explanation will be omitted. Reference numeral 8 in the figure is a cylindrical spacer made of synthetic resin whose cylindrical outer surface slides into contact with the inner surface of the guide 2. A protrusion 8a is formed protrudingly on the cylindrical outer surface, and the cylindrical inner surface is engaged (threaded) with the geared cable 3. ) Groove 8b is threaded to allow for this.
The spacer 8 is disposed near the top of the carriage 5 while being engaged with the geared cable 3. At this time, the protrusion 8a protrudes outward from the slit 2a of the guide 2, and surfaces B and C of the protrusion 8a can come into sliding contact with the end surfaces of the slit 2a, and the spacer 8
The rotation of the geared cable 3 is stopped,
This prevents the spacer 8 from shifting.

According to the above configuration, the spacer 8 that is in sliding contact with the inner surface of the guide 2 meshes with the geared cable 3, so that a sufficient thickness of the cylindrical portion of the spacer 8 can be ensured and molding can be facilitated. Further, the spacer 8 meshes with the geared cable 3 near the carriage 5,
Since it is in sliding contact with the inner surface of the guide 2, swinging of the geared cable 3 in the circumferential direction of the guide 2 is restricted. Therefore, the movement in the circumferential direction of the guide 2 of the carriage 5, which is caulked to the geared cable 3 near the spacer 8, is also restricted, thereby preventing collisions between the carriage 5 and the guide 2 caused by vibrations when the car is running. Prevent the occurrence of abnormal noise.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications are possible. For example, spacer 8 is the third
As shown in the figure, they may be placed near the bottom of the carriage 5 (see FIG. 3A) or near both ends of the carriage 5 (see FIG. 3B).

(Effect of the invention) As explained above, in the present invention, the cylindrical outer surface is in sliding contact with the inner surface of the guide, and the cylindrical outer surface is formed with a protrusion that fits into the slit, while the cylindrical inner surface is provided with a geared part. Using a roughly cylindrical synthetic resin spacer with a threaded groove that can engage with the cable,
Since this is meshed with the geared cable near the carriage, the spacer meshes directly with the geared cable, ensuring sufficient thickness of the cylindrical part of the spacer, making it easy to mold the spacer, and making it possible to easily mold the spacer. Since the spacer is attached to the geared cable by engaging the protrusion and restricting the rotation of the spacer with the protrusion, the attachment is easy and the attachment position will not shift. Moreover, as in the prior art, it is possible to restrict the movement of the carriage in the circumferential direction of the guide, thereby preventing the occurrence of abnormal noise due to collision between the carriage and the guide caused by vibrations when the vehicle is running.
