Abstract

A hinge includes a base receiving a coupling device detachably mounted onto a mounting seat. An outer resilient plate includes an end pivotably mounted onto the base. A fixed seat is pivotably mounted onto the other end of the outer resilient plate. A buffer device includes a connecting member, a buffer, and an inner resilient plate. Each of a first pivot hole of the connecting member, an end of the buffer, and an end of the inner resilient plate is pivotably mounted onto the base. The other end of the buffer is pivotably mounted onto a second pivot hole of the connecting member. The other end of the inner resilient plate is slideably mounted onto an arcuate slot of the connecting member. The inner resilient plate further includes a fulcrum pivot hole in at intermediate portion thereof. The fulcrum pivot hole is pivotably mounted by a pivot to the base.

Claims

1. A hinge comprising:

a base including a pivotal portion;

a coupling device received in the base, with the coupling device including a coupling portion;

a mounting seat including an assembling portion, with the coupling portion of the coupling device detachably mounted onto the assembling portion of the mounting seat;

an outer resilient plate including an end pivotably mounted onto the base;

a fixed seat pivotably mounted onto another end of the outer resilient plate; and

a buffer device including a connecting member, a buffer, and an inner resilient plate, with the connecting member including a first connecting plate having a first pivot hole, a second pivot hole, and an arcuate slot, with the first pivot hole, the second pivot hole, and the arcuate slot being not on the same line,

with each of the first pivot hole of the connecting member, an end of the buffer, and an end of the inner resilient plate being pivotably mounted onto the pivotal portion of the base, with another end of the buffer being pivotably mounted onto the second pivot hole of the connecting member, with another end of the inner resilient plate slideably mounted onto the arcuate slot, with the inner resilient plate further including a fulcrum pivot hole in intermediate portion there, with the fulcrum pivot hole being pivotably mounted by a pivot onto the pivotal portion of the base.

2. The hinge as claimed in claim 1, with the connecting member further including a second connecting plate identical to the first connecting plat, with the connecting member further including an intermediate plate interconnected between the first and second connecting plates, and with the first and second connecting plates having a spacing therebetween.

3. The hinge as claimed in claim 1, further comprising:

a spring mounted between a pivotal connection between the base and the outer resilient plate.

4. The hinge as claimed in claim 1, with the base including two lateral walls forming the pivotal portion, and with the connecting member, the buffer, and the inner resilient plate pivotably mounted between the two lateral walls of the base.

5. The hinge as claimed in claim 1, with the coupling portion of the coupling device including at least two first hooks facing inward, with the assembling portion of the mounting seat including at least two retaining portions, with said at least two first hooks removably engaged with said at least two retaining portions.

6. The hinge as claimed in claim 5, with the coupling device including an inner seat, a coupling member, and a resilient member, with the inner seat received in the base, with the inner seat including an end having at least one second hook, with the inner seat further including another end pivotably mounted onto the coupling member, with the coupling member including said at least two first hooks, with said at least one second hook of the inner seat facing said at least two first hooks of the coupling member, with the resilient member mounted onto a pivotal connection between the inner seat and the coupling member and biasing said at least two first hooks toward the inner seat.

7. The hinge as claimed in claim 6, with the inner seat including two lateral walls each having an end, with said at least one second hook of the inner seat including two second hooks respectively formed on the ends of the lateral walls of the inner seat, with said at least two first hooks of the coupling member including two first hooks, with the coupling member further including two lugs and a pressing board, with the two lugs of the coupling member pivotably mounted onto another ends of the two lateral walls of the inner seat, and with the pressing board facing outward of the inner seat.

8. The hinge as claimed in claim 7, with said at least two retaining portions respectively located on two ends of the mounting seat.

9. The hinge as claimed in claim 6, further comprising:

an adjusting member and a fixing member mounted between the base and the inner base, allowing adjustment in relative position between the base and the inner seat.
