Abstract

A hinge unit includes a hinge arm which defines a room in which a securing frame is installed. The securing frame includes two side panels with an engaging member connected therebetween. Each of the two side panels has an engaging portion on the inside thereof. The engaging member has a through hole and a protrusion extends from the periphery of the through hole. A damper has a body and a piston. The body has a front end portion having a recessed area, and a rear end portion having a protrusion. A fixing member connects the securing frame to the hinge arm. The piston extends through the through hole and the protrusion is engaged with the recessed area, the body of the damper is installed between the two side panels. The contact portion of the body contacts the engaging portion.

Claims

1. A hinge unit comprising:

a hinge base having two wings and a housing connected between the two wings;

a hinge arm pivotably connected to the hinge base and having two side walls and a bottom wall connected between the two side walls, each side wall having a first connection hole and a second connection hole, the two side walls and the bottom wall defining a room;

a securing frame having two side panels and an engaging member connected between the two side panels, each of the two side panels having a first connection portion, a second connection portion and an engaging portion, the first connection portion engaged with the first connection hole of the hinge arm, the second connection portion located corresponding to the second connection hole of the hinge arm, the engaging portion located on an inside of the side panels corresponding thereto and being adjacent to the second connection portion, the engaging member having a through hole and a protrusion extending from a periphery of the through hole;

a fixing member extending through the second connection holes of the side walls of the hinge arm and the second connection portions of the side panels of the securing frame so as to connect the securing frame to the hinge arm, and

a damper having a body and a piston, the body having a front end portion and a rear end portion, the front end portion having a recessed area and the rear end portion having a contact portion, the piston being axially movable relative to the body of the damper, the damper connected between the two side panels of the securing frame, the piston extending through the through hole of the engaging member, the protrusion of the engaging member engaged with the recessed area of the body, the contact portion of the body contacting the engaging portion of the side panels.

2. The hinge unit as claimed in claim 1, wherein the engaging member of the securing frame has an opening which communicates with the through hole and the protrusion extends toward the engaging portion.

3. The hinge unit as claimed in claim 1, wherein the contact portion of the damper is engaged with the engaging portion of the securing frame by an engagement relationship of protrusion and recess.

4. The hinge unit as claimed in claim 1, wherein the recessed area of the damper has a tubular portion which extends into the through hole of the engaging member.

5. The hinge unit as claimed in claim 1, wherein a connection member is located in the room of the hinge arm and the securing frame is connected in the connection member.

6. The hinge unit as claimed in claim 1, wherein the first connection portion is a protrusion.

7. A hinge unit comprising:

a hinge base having two wings and a housing connected between the two wings;

a hinge arm pivotably connected to the hinge base and having two side walls and a bottom wall connected between the two side walls, each side wall having a first connection hole and a second connection hole, the two side walls and the bottom wall defining a room;

a connection member located in the room of the hinge arm;

a securing frame installed in the room of the hinge arm, the securing frame having two side panels and an engaging member connected between the two side panels, each of the two side panels having a first connection portion, a second connection portion and an engaging portion, the first connection portion being a protrusion and engaged with the first connection hole of the hinge arm, the engaging portion located on an inside of the side panels corresponding thereto and being adjacent to the second connection portion, the engaging member having a through hole and a protrusion extending from a periphery of the through hole;

a fixing member extending through the second connection holes of the side walls of the hinge arm and the second connection portions of the side panels of the securing frame so as to connect the securing frame to the hinge arm, and

a damper having a body and a piston, the body having a front end portion and a rear end portion, the front end portion having a recessed area with which the protrusion of the securing frame is engaged, the rear end portion having a contact portion, the piston extending through the through hole of the engaging member and being axially movable relative to the body of the damper, the contact portion of the body contacting the engaging portion of the side panels.

8. The hinge unit as claimed in claim 7, wherein the engaging member of the securing frame has an opening which communicates with the through hole and the protrusion extends toward the engaging portion.

9. The hinge unit as claimed in claim 7, wherein the contact portion of the damper is engaged with the engaging portion of the securing frame by an engagement relationship of protrusion and recess.

10. The hinge unit as claimed in claim 7, wherein the recessed area of the damper has a tubular portion which extends into the through hole of the engaging member.
