Definitions
- the present invention relates to a retracting device that moves a rear shelf provided on a rear luggage compartment side up and down through a cord in conjunction with opening and closing of a tailgate of a hatchback vehicle, for example.
- the conventional retracting device has a pair of covers integrally provided on both sides of the rear surface of the rear shelf, and an elastic member having one end fixed to the cover body side in each cover body. And one end of a flexible member is connected to the other end of the elastic member, and the other end of the flexible member is fastened to the tailgate side of a hatchback vehicle. I have.
- the present invention has been developed in order to effectively solve the problems of the conventional retracting device. Disclosure of the invention
- the present invention provides a cylindrical cylinder, a biston moving in the cylinder, an urging spring for elastically urging the biston in one end direction in the cylinder, and a pull-in or pull-in with the movement of the biston.

Also, at this time, The cylinder 6 is rotated via the thin hinge 7 to lock its own locking claw 10 with the receiving claw 9 of the cylinder 1, thereby closing the opening at the other end of the cylinder 1. Become.
- one end 4 a of the string 4 guided from the through hole 12 of the cap 6 of each cylinder 1 to the outside through the inside of the above-described grommet G is connected to the tailgate of the hatchback car.
- the piston 2 moves inside the cylinder 1 against the elastic biasing force of the compression coil spring 3, as shown in Fig. 11.
- the cord 4 is pulled out sufficiently from the cylinder 1 and the compression coil spring 3 is Therefore, the rear end side of the rear shell S provided in the rear luggage compartment is moved upward by the tension of the string 4 obtained from this, and the luggage can be taken in and out of the rear luggage compartment.
- the distal ends of the pair of elastic arms 13 move while engaging with the corresponding concave long grooves 8.
- the rotation of the piston 2 in the cylinder 1 is reliably prevented, and the strings 4 sequentially hooked on the hooks 1 1 and 14 do not become entangled. Smooth withdrawal is guaranteed.
- the through hole 12 for drawing out the string 4 is provided at a position offset from the center, so the cylinder 1 is mounted on the rear shelf.

- the forked projection 16a of the separately formed clip 16 is inserted into the insertion hole 15 of the cylinder 11 in advance, and The ends of the compression coil spring 3 are supported by the projections 16a, and then the piston 2 is pushed into the cylinder 1 so that the pair of elastic arms 1 3 can be bent through the inside of the compression coil spring 3 while curving.
- simply removing the clip 16 from the cylinder 1 causes the end of the compression coil spring 3 to descend and come into contact with each elastic arm 13 of the biston 2.
- the retraction device can be easily assembled.
- two hooks 11 and 14 are formed on the cap 6 side and the biston 2 side, respectively, to reduce the size of the device itself including the cylinder 11.
- the present invention is not limited to this.
- three hooks 1 are provided on each of the cap 6 side and the piston 2 side. 1 and 14 or four hooks 1 1 and 1 4 on the cap 6 side and the piston 2 side, respectively, as shown in FIG. 4 3 caps on the 6 side as shown in C in Fig.
- a tension coil spring can be mounted between one end of the cylinder 11 and the piston 2, and the tension coil spring can be used as a biasing spring.
- the third embodiment is different from the first and second embodiments in that the rear gate S In order to prevent the end of the string 4 from moving up and down, when the end 4a of the string 4 is removed from the tailgate side, the retraction device itself has a damper function so that the end 4a of the string 4 is not suddenly drawn into the cylinder 1. Is provided.

- a flute shape facing the outside shall be given.
- the whole is formed into a disk shape
- the O-ring 20 is mounted on the outer periphery
- the groove 22 having the orifice 21 opened between the hooks 14 is formed.
- the other end portion 3 b bent toward the coil center of the compression coil spring 3 is fitted into the groove 22.
- the valve mechanism 18 provided at one end of the cylinder 1 forms a valve chamber 23 having an opening 24 at one end of the cylinder 1 as shown in FIG.
- a seat valve 26 having an air passage 26a is provided at a boundary between the valve chamber 23 and the cylinder 11 while a seat valve 25 for opening and closing the opening 24 is disposed therein.
- Air is allowed to flow into the hermetic chamber 17 through the gap between the valve chamber 23 and the passage 26 a of the stopper 26, and conversely, the piston 2 moves in the direction of one end of the cylinder 11.
- the seat valve 25 closes the opening 24 of the valve chamber 23 as shown in FIG. 16B. And it has a configuration to regulate the entry.
- the piston 2 moves, the seat valve 25 in the valve chamber 23 moves in a direction to open the opening 24 of the valve chamber 23, and the seat valve 25 Since air flows into the hermetic chamber 17 through the gap formed between the peripheral surface and the valve chamber 23 and the passage 26a of the stopper 26, the piston is used similarly to the first and second embodiments. As a result of the pile 2 moving only by the pressure of the compression coil spring 3, the damper effect cannot be obtained.
- the seal 4 closes the opening 24 of the valve chamber 23, and the air in the hermetic chamber 17 passes through the orifice 21.
- the hole diameter of the orifice 21 is set so that the maximum pulling speed of the string 4 can be restricted to 1.6 m / sec or less.
- grooves 19 and 22 are formed on the cap 6 and the piston 2 side, respectively, which are formed integrally with the cylinder 1 so that the compression coil spring 3 is folded. This is a configuration in which the bent terminal portions 3a and 3b are fitted.
- the piston 2 is reliably prevented from rotating in the cylinder 1, and The strings 4 that are sequentially hooked on the hooks 1 1 and 14 do not become entangled.
- the valve mechanism 18 is not limited to the above.
- a coil spring 2 that constantly biases the seat valve 25 in a direction to close the opening 24 of the valve chamber 23. It is optional that the opening 24 of the valve chamber 23 is opened and closed by the movement of the piston 2 with the intermediary of the piston 7.
- the string retraction device since the middle of the string is slidably hooked while being sequentially folded between the hooking portion on the piston side and the hooking portion on the cap side, The length of the string can be made much longer than the length, and the retraction device itself can be greatly reduced in size.
- the hook portion on the piston side is formed so as to sandwich the center of the piston, the piston can move smoothly in the cylinder without rattling.
- a rotation preventing means is provided between the cylinder and the piston, so that the string hooked on the biston side in the cylinder can be prevented from getting entangled, and the biston is elastically deformed to bias the spring.
- the string retraction device since the string retraction device according to the present invention has a damper function added to the device itself, at the time of the free retraction of the string, the string is prevented from being retracted while suddenly rolling around, and one end of the string is freely retracted. At this time, since the maximum retraction speed is regulated to 1.6 m / sec or less, braking force is applied to the retraction speed of the string, and the string is not pulled in at high speed. In addition, the presence of the detent means prevents the piston from rotating inside the cylinder, so that the string can be prevented from becoming entangled.
