Abstract

A hinge buffer device includes a casing, a slide, a buffer and an adjustment. The casing comprises a first end, a second end, a pair of lugs, a threaded hole, and a sliding trough. The lugs are disposed at two sides of the first end of the casing. The threaded hole is formed at the second end of the casing. The sliding trough is located between the first end and the second end of the casing. The slide comprises a compartment, a pair of sliding sections at respective sides to be engaged with the sliding trough of the casing. The buffer is a cylinder to be mounted in the compartment of the slide. The buffer comprises a piston rod secured to the slide. The adjustment is connected to the slide, and comprises a bolt to be engaged with the threaded hole of the casing.

Claims

1. A hinge buffer device comprising:

a casing comprising a first end, a second end, a pair of lugs, a threaded hole and a sliding trough, said lugs being formed at respective sides of said first end, said threaded hole being formed at said second end, said threaded hole'"'"'s axis being parallel with said sliding trough, said sliding trough being located between said first end and said second end;

a slide comprising a compartment and a pair of sliding sections at respective sides thereof corresponding to said sliding trough of said casing;

a buffer being a cylinder having a piston rod secured to said slide, said cylinder being disposed in said compartment of said slide; and

an adjustment comprising a bolt screwed to said threaded hole of said casing and being connected to said slide, by rotating said bolt to link said slide to move simultaneously.

2. The hinge buffer device, as recited in claim 1, wherein each of said lugs has a through hole corresponding to a threaded hole of a hinge base.

3. The hinge buffer device, as recited in claim 1, wherein said slide comprises a trough, and said adjustment comprises a stud corresponding to said trough of said slide.

4. The hinge buffer device, as recited in claim 3, wherein said trough has a cross sectional shape that resembles an English letter T, and said stud has a cross sectional shape that resembles an English letter T.
