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 formed at respective sides of said first end, a pair of sliding rails extending along respective edges of said casing between said first and second ends thereof, a sliding trough defined at said casing between said sliding rails and extending between said first and second ends, wherein said second end has a threaded hole formed thereat, an axis of said threaded hole being parallel with said sliding trough;

a slide comprising a compartment and a pair of sliding sections at respective sides thereof corresponding to said sliding trough of said casing, said pair of sliding sections of said slide being movable in the sliding trough of the casing;

a cylinder body disposed in said compartment of said slide and having a part protruding outside of said compartment of said slide, said protruding part having a contact end;

a piston rod linearly movable in said cylinder, said piston rod being secured to said slide; and

an adjustment comprising a bolt threadedly engaged within said threaded hole of said casing and coupled to said slide, wherein rotation of said bolt results in substantially simultaneous motion of said slide along said casing, thereby adjusting a relative disposition between said contact end of said cylinder body and said first end of said casing.

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

3. The hinge buffer device, as recited in claim 1, wherein said slide comprises a trough formed at one end thereof, and wherein said adjustment comprises a stud engaged in said trough of said slide.

4. The hinge buffer device, as recited in claim 3, wherein said trough of said slide, and said stud are formed with their respective cross sections T-shaped.

5. The hinge buffer device, as recited in claim 1, wherein said bolt of said adjustment is provided with a knob.

6. A hinge buffer device, comprising:

a hinge base having a pair of holes;

a hinge extension arm pivotably connected to the hinge base;

a casing comprising a first end, a second end, a pair of lugs formed at respective sides of said casing, and a pair of sliding rails extending along respective edges of said casing between said first and second ends thereof, a sliding trough defined at said casing between said sliding rails and extending between said first and second ends, wherein each said lug has a through hole corresponding to a respective one of the pair of holes of said hinge base;

a slide comprising a pair of sliding sections slidably connected to said sliding trough of said casing, said slide including a longitudinal compartment defined internally thereof;

a cylinder body disposed in said compartment of said slide and having a part protruding outside of the compartment of said slide, said protruding part having a contact end engaging the hinge extension arm to buffer the relative pivotal motion between said casing and said hinge extension arm; and

a piston rod linearly movable in said cylinder body, said piston rod being secured to said slide member.

7. A hinge buffer device, comprising:

a casing comprising a first end, a second end, a pair of sliding rails extending along between the first and second ends, and a sliding trough defined at the casing between the pair of sliding rails;

a slide slidably connected to the sliding trough of the casing, the slide comprising a compartment;

a buffer comprising a cylinder body and a piston rod linearly movable in the cylinder body, the cylinder body being disposed in the compartment of the slide, and one part of the cylinder body protruding outside of the compartment of the slide; and

an adjustment connected between the casing and the slide, the adjustment comprising a bolt threadedly engaged in either of the casing and the slide;

wherein rotation of the bolt results in substantially simultaneous motion of the slide along the casing, thereby adjusting a relative disposition between the cylinder body of the buffer and the casing.
