SHOCK ABSORBING AND HEIGHT ADJUSTING STRUCTURE
First Claim
1. A shock absorbing and height adjusting structure, comprising:
- an inner tube, comprising;
an upper end;
a lower end opposite to the upper end; and
an inner space for accommodating a gas;
a lower piston assembly, comprising;
a lower piston movably inserted into the inner tube; and
a lower passage disposed at the lower piston; and
an upper piston assembly comprising an upper piston movably inserted into the inner tube;
wherein when the lower passage is opened, the lower piston is moved relative to the lower end; and
when the upper piston is forced, the upper piston is moved relative to the upper end toward the lower end so as to compress the gas.

Abstract
A shock absorbing and height adjusting structure includes an inner tube, a lower piston assembly and an upper piston assembly. The inner tube includes an upper end, a lower end opposite to the upper end, and an inner space for accommodating a gas. The lower piston assembly includes a lower piston movably inserted into the inner tube, and a lower passage disposed at the lower piston. The upper piston assembly includes an upper piston movably inserted into the inner tube. When the lower passage is opened, the lower piston is moved relative to the lower end, and when the upper piston is forced, the upper piston has movement relative to the upper end toward the lower end to compress the gas.

15. A shock absorbing and height adjusting structure, comprising:
-
an inner tube, comprising; an upper tube body, comprising an upper end and a first connecting end opposite to the upper end; and a lower tube body, comprising a lower end and a second connecting end opposite to the lower end, wherein the second connecting end is connected to the first connecting end; an upper piston assembly, comprising; an upper piston movably inserted into the upper tube body and adjacent to the upper end; and an upper passage disposed at the upper piston; and a lower piston assembly, comprising; a lower piston movably inserted into the lower tube body and adjacent the lower end; and a lower passage disposed at the lower piston; wherein when the upper passage is opened and the lower passage is closed, the upper piston is moved relative to the upper end while a position of the lower piston relative to the lower end is fixed;
when the lower passage is opened and the upper passage is closed, the lower piston is moved relative to the lower end while a position of the upper piston relative to the upper end is fixed; and
when the upper piston is forced, the upper piston is moved relative to the upper end toward the lower end so as to compress a gas. - View Dependent Claims (16)
