Description

[Detailed Description of the Invention] This invention relates to a retainer particularly suitable for holding a vehicle height adjustable shock absorber in a contracted state.

A vehicle height adjustable shock absorber shown in FIG. 1 is known.

This vehicle height adjustable shock absorber A has a cap 3 provided on the upper side of a cylinder 2 into which a rod 1 is slidably inserted.

The cap 3 is movable relative to the cylinder 2, and a diaphragm 4 closes the gap between the lower end opening of the cap and the cylinder, forming a pressure chamber 5 within the cap 3.

Gas pressure is supplied to the pressure chamber 5 formed as described above through its sealing port 6, so that the height of the vehicle can be adjusted.

When transporting the above-mentioned shock absorber, it is contracted to make it compact, and a retainer is used to maintain its contracted state.

(Conventional Retainer) This type of retainer that has been known in the past can be constructed by simply opening the filling port 6, contracting the shock absorber A, and then wrapping the retainer made of a string or the like in this state. It was hot.

However, if the shock absorber A is left in the above state for a long time, the folded portion x of the diaphragm 4 in that state becomes curly or the folded portion x comes into close contact.

Therefore, during actual use, the diaphragm 4 does not turn over smoothly, causing problems such as damage to the diaphragm 4.

In order to solve this problem, in the past, a peeling agent such as oil was applied to the inside of the folded part x,
Alternatively, pressure is sealed in the pressure chamber 5 even during transportation or the like.

However, when a release agent is applied as described above, there is a drawback that the release agent may adhere to other devices, thereby affecting the operation of other devices.

In addition, when pressure is sealed in the pressure chamber 5, the shock absorber A becomes fully extended due to the pressure, resulting in a drawback that the space required during transportation becomes large.

(Objective of the Present Invention) The purpose of the present invention is to provide a retainer that prevents the diaphragm from being damaged even when the shock absorber is in a contracted state.

(Embodiment of the present invention) In the illustrated embodiment, a stopper 8 for blocking the sealing opening 6 is fixed to a required location of an endless string member 7.

With the shock absorber A extended, the filling opening 6 is first plugged with the stopper 8. With the sealing port 6 blocked in this manner, the shock absorber A is contracted and the string member 7 is hung as shown in FIG.

By wrapping the string member 7 as described above, the shock absorber A maintains its contracted state, and the volume inside the pressure chamber 5 decreases during this contraction process, so that the pressure inside the pressure chamber 5 decreases. occurs. The pressure generated in the pressure chamber 5 causes the folded portion x of the diaphragm 4 to swell, thereby preventing the folded portion x from coming into close contact with each other, and also preventing the folding from occurring.

Further, when the shock absorber A is maintained in the contracted state as described above, the string member 7 is tensed, and the tension of the string member 7 acts as a force to prevent the stopper 8 from being pulled out. do.

The string member in the present invention may have any form as long as it can be stretched in the longitudinal direction of the shock absorber and maintain its contracted state. For example, instead of having an endless shape as in the above embodiment, it may be a single string with loops formed at both ends.

Furthermore, if the tension force of the string member 7 acts on the stopper 8, the purpose can be achieved, so the stopper 8 only needs to be made to correspond to the sealing opening 6 of the shock absorber.

(Configuration of the present invention) The configuration of the present invention is to provide a cap on one side of the cylinder, provide a diaphragm between the cap and the cylinder, form a pressure chamber within the cap, and reduce the pressure within the pressure chamber. The shock absorber is adapted to adjust the height of the vehicle by adjusting the height of the vehicle, and the strap member is provided with a string member that extends in the longitudinal direction of the shock absorber to maintain its contracted state. The pressure chamber is characterized in that it includes a stopper that closes a sealing port for sealing pressure into the pressure chamber.

With the above structure, the pressure can be maintained in the pressure chamber by blocking the sealing port of the pressure chamber with a stopper while the shock absorber is extended, and then contracting the shock absorber.

With the pressure maintained in the pressure chamber in this way,
By wrapping the string member, the shock absorber can be maintained in a contracted state.

(Effects of the Present Invention) With the configuration as described above, if the shock absorber is maintained in a contracted state by the retainer, pressure can be maintained in the pressure chamber. Since the pressure can be maintained in the pressure chamber, the folded part of the diaphragm bulges, and the folded part becomes curly.
Or not in close contact.
