Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cable support device suitable for application to, for example, a parking cable that connects a parking lever of an automobile parking brake to a brake mechanism.

(Prior Art) An automobile is provided with a parking brake to prevent the vehicle from moving when parked. This parking brake device has a structure in which a parking brake lever and a wheel-side brake device are connected by a parking brake cable. It is known that this parking cable vibrates in three dimensions while the car is running, and therefore it is supported with a structure that can withstand this vibration. Fourth
This will be explained with reference to the diagram. In this figure, 1 is a parking cable (hereinafter referred to as a cable), and 2 is a portion of the vehicle body that supports this cable 1. One end (not shown) of the cable 1 is connected to a parking brake lever in the vehicle interior, and the other end is connected to a brake device on the wheel side. A spring 3 is disposed on the outer periphery of the cable 1. The spring 3 has a portion 3a that supports the cable 1 with ease, and a portion 3b that extends from this portion 3a to the vehicle body 2. The tip of a portion of the spring 3 indicated by reference numeral 3b is fixed to the vehicle body 2 with a bolt 4.

(Problem to be solved by the invention) The conventional cable support device with this configuration is
The three-dimensional vibrations applied to the cable while the vehicle is running are absorbed and supported by the spring 3, but since the cable 1 is simply supported by the spring 3, the degree of vibration absorption and cable protection are limited. In this respect, it was still far from perfect, and there was still room for further improvement. The present invention was made with the aim of solving this problem.

(Means for Solving the Problems) The present invention is a means for solving the above problems by providing a hole with a slightly larger inner diameter than the cable in order to insert the cable in the center and having a gap for the cable to slide through. At the same time, a resin pulley with a groove formed on the outer periphery of a circular shape is provided, a cable is inserted into the hole of the pulley, and one end of a coil spring having a diameter smaller than the width of the groove is inserted into the groove. The pulley is wound so as to be relatively movable in the groove width direction, and the pulley is connected to a part of the vehicle body by the coil spring.

(Function) With this configuration, the pulley, which has a slightly larger inner diameter than the cable and has a hole with a gap for the cable to slide, allows the cable to move in the axial direction while restricting movement beyond the limit. In addition, one end of the coil spring, which has a diameter smaller than the groove width, is wound around the groove so that it can move in the groove width direction, and the pulley is connected to a part of the car body, so that the spring can be used as a cable. This allows the pulley to move vertically and horizontally within a predetermined range. Therefore, without causing any damage to the cable,
It can absorb vibrations caused by driving a car.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2, in which the same members as those in FIG. 4 are given the same reference numerals. It is designed to be supported via a pulley 5. The pulley 5 is made of resin and has a circular shape as a whole as shown in FIG. 3, and has a hole 6 in the center thereof through which the cable 1 is inserted, and a groove 7 in the outer periphery. The inner diameter of the pulley 5, that is, the diameter of the hole 6, is slightly larger than the outer diameter of the cable 1 to form a gap in which the cable 1 can slide. The cable 1 is inserted through a hole 6 of a pulley 5, and the pulley 5 is supported by winding one end of a coil spring (hereinafter referred to as a spring) 8 around a groove 7. In this case, as shown in FIG. 1, the width of the groove 7 of the pulley 5 is sufficiently wider than the diameter of the spring 8. It is designed to be able to move relatively in the groove width direction. The other end of the spring 8 is secured to the vehicle body 2 by a bolt 4. The spring 8 used in this case differs from the conventional spring 3 shown in FIG. 4 in that it is a conventional spring wound in a fixed direction with one end portion extended.

This device configured in this way is designed to connect the cable 1 in the axial direction (A in Fig. 1,
When vibration is applied in the three-dimensional directions (B direction), vertical direction (C and D in the same figure), and left and right direction (E and F directions in Figure 2), out of this vibration, the A and B directions and the cable 1 Vibration in the torsional direction is allowed by the pulley 5 sliding on the cable 1 and is damped without being restrained. In addition, the vertical and horizontal directions (C, D
Vibrations in the E and F directions are absorbed and attenuated by the expansion and contraction of the spring 8 that supports the pulley 5, and by the swinging in the E and F directions centered around the bolt 4 in Fig. 2. .

(Effects of the invention) Since the present invention is a cable support device configured as explained above, only the pulley is in direct contact with the cable, so there is no damage to the cable, and the structure is simple. Therefore, it can be realized at low cost.
