Abstract

A hinge assembly suppressing periodic motions and abrasive wear that supports an axial load and integrated a releasable hinge pin with retractable latch pins. The connector arms for the hinge assembly may include bearings, smooth outer surfaces, and tight fittings to help suppress the periodic motions and abrasive wear. Adjustable mounting apertures reduce stress on the hinge system. A hinge aperture for each member enables an axial load arm, such as thrust bearings, to pass through for reducing periodic movements during pivotal operation. A lock arm can also pass through the hinge apertures. The lock arm uses a locking pin to fasten the members together. A smooth outer surface inhibits abrasive wear and creates a smooth pivoting motion. Non-circular mounting apertures may enable adjustable mounting for reducing stress on the system.

Claims

1. A hinge for reducing a periodic motion while supporting an axial load, the hinge comprising:

a first hinge assembly configured to at least partially support an axial load, and rotatable to move a door between an open position and a closed position, the first hinge assembly comprising a first jamb member disposed to attach to one of a door and a jamb, the first jamb member defining a first jamb hinge aperture, the first jamb member further defining a plurality of first jamb mounting apertures configured to enable passage of at least one fastener for fastening the first hinge assembly to one of the jamb and the door,

wherein at least one of the first jamb mounting apertures having a noncircular cross section for enabling adjustable mounting of the first hinge member,

a second hinge assembly configured to cooperate along a common axis of a door with the first hinge assembly and having a common longitudinal axis so that the first and second hinge members are rotatable to move the door between the open position and the closed position, wherein the second hinge assembly comprises a second jamb member disposed to attach to one of a door and the jamb, the second hinge member defining a second jamb hinge aperture circumscribed by an annular recess, the second jamb hinge aperture comprising a jamb slot adapted to enable passage of a releasable hinge pin for fastening the second hinge member to the first hinge member,

wherein first hinge assembly and second hinge assembly are adapted to enable passage of the releasable hinge pin, the releasable hinge pin comprising;

a depressible, spring-loaded button protruding upwardly from a proximal top end of the hinge pin, the depressible, spring-loaded button adapted to retract two latch pins protruding laterally from a cylindrical body of the hinge pin.

2. The hinge of claim 1, in which the door and the jamb are configured for a bookcase.

3. The hinge of claim 2, in which the axial load comprises a weight of the bookcase and at least one item in the bookcase.

4. The hinge of claim 1, in which the noncircular cross section enables a vertical adjustment during mounting.

5. A hinge for reducing a periodic motion while supporting an axial load, the hinge system comprising:

a first jamb member comprising a thrust bearing and defining a first jamb hinge aperture, the first jamb hinge adapted to enable passage of a releasable hinge pin, the first jamb hinge defining a plurality of mounting apertures having non circular cross sections;

a second door member defining a second jamb hinge aperture circumscribed by an annular recess and door slot, the second jamb hinge adapted to enable passage of the releasable hinge pin;

a releasable hinge pin, the releasable hinge pin traversing the first jamb member and the second door member comprising;

a depressible, spring-loaded button protruding upwardly from a proximal top end of the hinge pin, the depressible, spring-loaded button adapted to retract two latch pins into a cylindrical body of the hinge pin;

wherein the hinge is configured to at least partially support an axial load, and rotatable to move a door between an open position and a closed position.

6. A hinge for reducing a periodic motion while supporting an axial load, the hinge system consisting of:

a first jamb member defining a first jamb hinge aperture, the first jamb hinge adapted to enable passage of a releasable hinge pin, the first jamb hinge defining a plurality of mounting apertures;

a second jamb member defining a second jamb hinge aperture circumscribed by an annular recess and door slot, the second jamb hinge adapted to enable passage of a releasable hinge pin;

a releasable hinge pin, the releasable hinge pin comprising;

a depressible, spring-loaded button protruding upwardly from a proximal top end of the hinge pin, the depressible, spring-loaded button adapted to retract two latch pins into a cylindrical body of the hinge pin;

wherein the hinge is configured to at least partially support an axial load, and rotatable to move a door between an open position and a closed position.
