Description

[Detailed Description of the Invention] "Technical Field" The present invention relates to a geared cable used as a driving member for a vehicle's wind regulator, sliding roof, etc.

"Prior Art and its Problems" A geared cable is made by winding and fixing a wire spirally around the outer periphery of a linear inner cable, and this peripheral wire meshes with a wire gear. When the wire gear is driven to rotate, the entire geared cable moves in the axial direction, so the driven object connected to the geared cable moves. That is, in the case of a wind regulator, the window glass connected to the geared cable is opened and closed, and in the case of a sliding roof, the roof member is opened and closed.

Conventionally, this geared cable has been flocked on its circumferential surface in order to reduce noise when meshing with a wire gear or to reduce frictional resistance with a guide pipe into which it is inserted. 7th
The figure shows the manufacturing procedure of the conventional geared cable 10. After applying an adhesive to the outer periphery of a linear inner cable 11, a low-friction pile such as nylon pile is assembled by means such as electrostatic flocking. 12 is flocked, and then a wire 13 is wrapped around the pile 12 and fixed.

However, in this conventional flocked geared cable, when an overload is applied, the wire 13 slips relative to the inner cable 11, and as a result, the wire 1
3 pitch deviation may occur. In other words, there was a problem that the load capacity and durability were poor, and since the pile 12 is flammable, heat treatment after fixing the wire 13 to the inner cable 11 is impossible. Difficult to give character or strength. Furthermore, when the geared cable 10 is inserted into the guide pipe, the inner surface of the pipe and the wire 13 come into strong contact, especially at the bends in the guide pipe, which tends to cause abnormal noise due to friction.

"Purpose of the Invention" The purpose of the present invention is to solve the problems of the conventional geared cables and to obtain a geared cable with improved load resistance, sound deadening properties, and friction properties.

"Summary of the invention" This invention solves the problem of conventional geared cables.Since the wire is wrapped around the inner cable after flocking, the flocking (pile) tends to slip between the inner cable and the outer wire. This was done based on the recognition that this was caused by the fact that That is, the geared cable of the present invention includes an inner cable, a wire that meshes with a wire gear that is spirally wound around the outer periphery of the inner cable and fixed thereto, and hair flocking applied to the surface of a combination of these inner cables and wires. It is characterized by

``Embodiments of the invention'' The invention will be described below with reference to illustrated embodiments. FIG. 1 shows the manufacturing procedure of the geared cable 10 of the present invention. Before flocking the outer periphery of the inner cable 11, the wire 13 is wound helically, and then the entire inner cable 11 and wire 13 are wrapped. After applying the adhesive, the piles 12 are flocked on the surfaces of the inner cable 11 and the wires 13, for example, by electrostatic flocking.

According to this geared cable 10, since the inner cable 11 and the wire 13 are in direct contact, the coefficient of friction between them is large. Yotsute wire 13
The load at which the cable starts to slip on the inner cable 11 is much greater than that of a conventional geared cable. Since not only the surface of the inner cable 11 but also the surface of the wire 13 is covered with the pile 12, the frictional resistance between the wire gear or guide pipe and the geared cable 10 is reduced, and no abnormal noise is generated. Further, it is possible to wrap the wire 13 around the inner cable 11 and heat-treat it, and then flock the pile 12, so that the geared cable 10 can be given desired properties by the heat treatment.

The geared cable 10 described above is used for wind regulators, sliding roofs, etc. as described above.
With reference to the figure, a specific example of use in a wind regulator will be described. A door panel 21 having an inner panel 21a and an outer panel 21b supports a window glass 22 so as to be movable up and down.
The inner panel 21a has a mounting bracket 23,
A guide pipe 25 is fixed via 24, and the geared cable 10 is slidably housed within this guide pipe 25. Note that 25d in FIG. 4 is a low-friction synthetic resin layer provided on the inner surface of the guide pipe 25.

This guide pipe 25 has a vertical portion 25a.
, a bent portion 25b, and an inclined portion 25c. The geared cable 10 has flexibility to move freely within the guide pipe 25.

As shown in FIG. 4, a notch 26 that is continuous in the axial direction is formed in the vertical portion 25a of the guide pipe 25. As shown in FIG. The mounting bracket 27 that supports the lower end of the window glass 22 has a neck portion 27a passing through the notch 26, and a shaft portion 27b that is slidably fitted into the vertical portion 25a. is the above geared cable 10
It is integrated into the bottom edge of the. A glass holder 28 directly holds the lower end of the window glass 22. This glass holder 28 is fixed to the mounting bracket 27 via an intermediate bracket 29, so that the mounting bracket 27 and the window glass 22 are integrated. Therefore, with the above configuration, when the geared cable 10 is moved within the guide pipe 25,
The window glass 22 moves up and down.

A drive mechanism 30 for moving the geared cable 10 in its axial direction is provided on the inclined portion 25c of the guide pipe 25. This drive mechanism 30
As shown in FIG. 5, a case 31 fixed to the inner panel 21a, a wire gear 32 housed in the case 31, a handle shaft 33 rotatably supporting the wire gear 32, and a handle shaft 33 are connected to the case 31 fixed to the inner panel 21a. It consists of a fixed handle 34 and a braking means 35 interposed between the handle shaft 33 and the wire gear 32.
The wires 13 of the geared cable 10 exposed from the Figure) are engaged.

In this embodiment, the teeth 36 of the wire gear 32 have a tooth profile parallel to the axis of the wire gear 32, as shown in FIG. The teeth 36 are shown in FIG. 6d.
As shown in an enlarged view, at least one of the diagonal corner portions 36c, 36c contacts the wire 13 of the geared cable 10 (or the pile 12 flocked thereto).

As shown in FIG. 5, the well-known braking means 35 has a stopper plate 40 that is integrally fixed to the wire gear 32 and fitted to the shaft portion 33a of the handle shaft 33 so as to be relatively rotatable. , the tongue portion 40a of this plate fits into a notch 33b formed in the handle shaft 33. Furthermore, the torsion spring 42 wound around the handle shaft 33 is
The spring comes into elastic contact with the inner surface of the case 31 with a force that tries to expand its diameter, and both ends of the spring are attached to the handle shaft 3.
3, and the tongue portion 40a of the stopper plate 40 is located between them. When a rotational force is applied to the handle 34, the notch 33b
The diameter of the torsion spring 42 engaged with is reduced, the elastic contact force between the spring 42 and the inner wall surface of the case 31 is weakened, and the handle shaft 33 is rotated.
This rotation is transmitted to the wire gear 32 via the stopper plate 40, and as the wire gear 32 rotates, the geared cable 10, in which the teeth 36 and the wire 13 are engaged, slides inside the guide pipe 25, and the windshield The glass 22 moves up and down. Conversely, when an attempt is made to rotate the wire gear 32 and stopper plate 40 by applying a lifting force to the windshield 22, the tongue portion 40a of this plate hits the end of the torsion spring 42, expanding the diameter of the spring. To make the torsion spring 4
2 and the inner wall surface of the case 31 increases, the handle shaft 33 does not rotate, and therefore the wire gear 3
2 also does not rotate, so the window glass 22 does not move. In FIGS. 2 and 3, 44 is an auxiliary pipe connected to the tip of the guide pipe 25, and serves to guide the geared cable 10 when it overslides the guide pipe 25.

As described above, in the wind regulator having the above configuration, when the wire gear 32 is rotated via the handle 34, the teeth 36 of the wire gear 32 and the wire 13 of the geared cable 10 engage with each other, so that the geared cable 10 is moved in the axial direction. The window glass 22 can be moved up and down. At this time, according to the geared cable 10 of the present invention, since the pile 12 is planted not only on the surface of the inner cable 11 but also on the surface of the wire 13, no abnormal noise is generated when meshing with the wire gear 32. . In particular, the wire gear 3 shown in this embodiment
2, since the teeth 36 are parallel to the axis of the gear 32, at least one of the corner portions 36c, 36c of the teeth 36 (strictly speaking, the one according to the rotating direction of the wire gear 32) hits the wire 13. However, even with such a contact relationship, no abnormal noise is generated. Also geared cable 1
0, the curvature changes greatly at the bent portion 25b of the guide pipe 25, but since the friction with the guide pipe 25 can be reduced by the pile 12, no abnormal noise occurs in this portion either.

Of course, the wire gear 32 may be a gear whose teeth are inclined according to the lead angle of the wire 13, but since the gear 32 of the embodiment can be press-molded, it has the advantage that it can be provided at low cost. By combining this gear 32 and the present geared cable 10, smoother operation can be ensured.

``Effect of the invention'' As described above, the geared cable of this invention has hair flocking on the surface of the combined body of the inner cable and the wire wrapped and fixed around its outer periphery, so that the integrity of the inner cable and wire is maintained. In addition to increasing the load capacity and durability, it also reduces the overall coefficient of friction and eliminates abnormal noise caused by meshing with wire gears, or abnormal noise in parts of the guide pipe with particularly large curvature. The occurrence can be effectively prevented. Further, by applying heat treatment to the inner cable with the wire wound and fixed around the outer periphery of the inner cable before flocking, the mechanical properties can be adjusted by the heat treatment to obtain a geared cable with desired properties.
