Description

[Detailed Description of the Invention] This invention relates to a telescoping operation tool for operating a seat vertical movement mechanism of a front seat of an automobile, for example.

2. Description of the Related Art A front seat is known that is equipped with a seat vertical movement mechanism that allows the front seat to move up and down according to the height of the driver to adjust the driving position to an appropriate position.

A seat vertical movement mechanism is provided inside the seat frame, and by rotating an operating tool, the seat vertical movement mechanism is operated and the seat body can be moved up and down.

By the way, the above-mentioned operating tool has conventionally been composed of an outer cylinder and an inner cylinder inserted into the outer cylinder so as to be slidable in the axial direction, and the inner cylinder is urged by a spring in the direction of retracting into the outer cylinder. There is. A synthetic resin cap that slidably guides the inner cylinder is fitted into one end opening of the outer cylinder, and a grip is fitted into the tip of the inner cylinder.

Therefore, when operating the seat vertical movement mechanism, the inner cylinder is extended by grasping the grip and pulled out against the biasing force of the spring, so that rotational operation can be performed with a small torque. In addition, when you release your hand from the grip after operation, the inner cylinder will be retracted into the outer cylinder by the biasing force of the spring, so it will shorten.
It does not get in the way when not in use.

However, conventional telescoping operating tools are configured so that when the inner cylinder is retracted into the outer cylinder by the biasing force of the spring, the grip comes into contact with the cap and stops, so there is no space between the grip and the cap. They can pinch your hands and fingers, causing injury, and they can also pinch your clothes, damaging them.

This idea was devised by paying attention to the above-mentioned circumstances, and its purpose is to provide a damper at the end of the inner cylinder that comes into contact with a stopper in the outer cylinder, so that there is a gap between the cap and the grip when the cap is immersed. The purpose of the present invention is to provide a telescoping operating tool which is highly safe and does not have clothing or fingers caught between the cap and the grip by forming a gap.

An embodiment of this invention will be described below based on the drawings. Reference numeral 11 in FIG. 1 indicates a seat body of a front seat of an automobile, which is composed of a seat cushion 12 and a seat back 13. The seat body 11 is supported by a seat frame 15 fixed to a floor 14, and a seat vertical movement mechanism 16 is provided inside the seat frame 15. The seat body 11 can be moved up and down by the seat vertical movement mechanism 16, and the height of the seat can be arbitrarily adjusted according to the driver's preference. Furthermore, a telescoping operating tool 17 for operating the seat vertical movement mechanism 16 is provided on the side surface of the seat frame 15, and this telescoping operating tool 17 is covered with a cover 18. The telescoping operating tool 17 will be described in detail as being constructed as shown in FIGS. 2 to 4. That is, 19 is an outer cylinder, and inside this outer cylinder 19 is an inner cylinder 20.
is inserted so that it can freely slide in the axial direction. A stopper 21 is provided at the base end of the outer cylinder 19, and the opening at the tip is made of a synthetic resin material.
A cap 23 having an insertion hole 22 through which the 0 is slidably guided in the axial direction is fitted. moreover,
An annular groove 24 is provided on the inner peripheral surface of the opening at the tip of the outer cylinder 19, and a collar 25 made of a synthetic resin material guides the inner cylinder 20.
is fitted. Further, a grip 26 is fitted to the tip of the inner cylinder 20, and one end of a spring 27 is fixed by this grip 26. This spring 27 is inserted in the longitudinal direction of the inner cylinder 20, and the other end thereof is connected to the untwisting tool 2.
8 to the stopper 21.
Therefore, the inner cylinder 20 is always urged by the spring 27 in the direction of sinking into the outer cylinder 19. Further, an annular groove 29 is provided on the outer circumferential surface at the end of the inner cylinder 20, and a synthetic resin collar 30 is fitted into this annular groove 29.
A damper 31 made of a soft synthetic resin pipe is fitted onto the outer peripheral surface of the outer cylinder 20 on the distal end side. This damper 31 protrudes rearward from the end surface of the inner cylinder 20, and when the inner cylinder 20 is retracted, this damper 31 comes into contact with the stopper 21 to form a gap 32 between the cap 23 and the grip 26. I'm starting to do that.

When the grip 26 is grasped and pulled out, the inner cylinder 20 expands against the biasing force of the spring 27, so it can be rotated with a small torque. The inner cylinder 20 sinks into the outer cylinder 19 due to the force. Then, the damper 31 of the inner cylinder 20 comes into contact with the stopper 21 and stops, forming a gap 32 between the cap 23 and the grip 26. Therefore, fingers or clothes are not caught between the cap 23 and the grip 26, and since the damper 31 is made of a soft synthetic resin material, it can buffer the impact when it collides with the stopper 21.

In the above embodiment, the collar 30 and the damper 31 are constructed as separate bodies, but the present invention is not limited to this, and the damper 31 may be integrally constructed as shown in FIG. 5.

Further, the telescoping operating tool of this invention is not limited to the operating tool for a seat vertical movement mechanism.

As explained above, according to this invention, since a damper is provided at the end of the inner cylinder that comes into contact with a stopper in the outer cylinder, a gap is formed between the cap and the grip when the inner cylinder is retracted. This improves safety by not pinching fingers or clothing, and the damper also has the effect of reducing the impact upon collision with the stopper.
