Abstract: The present disclosure provides a system for sealing a compartment. The system includes a door with a seal positioned on a bottom surface of the door. The system also includes one or more hinges coupled to the door. The door rotates from a closed position to an open position via the one or more hinges. A height of the door with respect to a floor surface increases in response to a rotation of the door from the closed position to the open position due to a helical slope of both a first cam surface of the one or more hinges and a second cam surface of the one or more hinges. The seal transitions from a compressed state to a relaxed state in response to the rotation of the door from the closed position to the open position.

Abstract: A collapsible device includes a base, a cover, and a hinge. The hinge includes a first connecting member fixed to the base, a second connecting member defining a through hole, a sleeve member fixed to the second connecting member, a shaft movably mounted to the first connecting member, and a fastener. The sleeve member defines a spiral slide groove therein. A clamping protrusion extends from the first connecting member for slidably engaging in the slide groove. The shaft includes a fixing portion rotatably passed through the sleeve member and the through hole. The fastener is fixed to a distal end of the fixing portion. The second connecting member is fixed to the cover. During the rotation of the cover relative to the base via the hinge, the cover is synchronously moved transversely relative to the base along the axial direction of the hinge.

Abstract: A door assembly for pivotally securing a door to an animal enclosure or other enclosure. The door assembly comprises a pivot pin assembly integrally formed with the door and a hinge secured to the enclosure adjacent the opening. The pivot pin assembly preferably comprises a vertically oriented pivot pin integrally formed with upper and lower horizontal support members extending from upper and lower ends of the pivot pin across a portion of the door. The pivot pin is fitted within a hinge barrel formed within the hinge in a manner to permit the pivot pin to rotate within the barrel such that the door may be pivoted from an open to a closed position.

Abstract: An automatic closing door hinge, an automatic closing door mechanism, and a hinge of the automatic closing door mechanism, for smoothly opening a door or closing, with damping, a door. For example, an automatic door closing mechanism has a hinge having a pair of wing plates one of which has a cylinder in a circular cylindrical form received therein a piston, the other wing plate fixing an upper portion of an operation rod engaged with the piston, the piston being to be advanced and retracted through the operation rod associatively with a rotation of the other wing plate.

Abstract: For swingably mounting a door on a jamb, a dual action self closing hinge has a stationary component which seals, shields, and carries a stationary cam and a rotatable cam follower. The cam elements cooperate with one another to displace the cam follower and attached door panel upwardly during an opening movement and permit the automatic downward movement of the cam follower and door panel upon release of the door panel from an open position. Simultaneous with the cam action, an offset hinge mechanism elevates the center of gravity of the door panel during opening, and likewise provides for the automatic return of the door panel to the closed position to improve the self-closing action of the door. In addition, a cam angular position lock enables the closed position of the door relative to the jamb to be easily adjusted.

Abstract: A hinge for rotatably mounting a barrier member to a structural member. The hinge comprises a first hinge assembly which comprises a first hinge bracket attachable to the structural member, a second hinge bracket attachable to the barrier member, a first hinge member mounted for rotation with the second hinge mounting bracket and a second hinge member mounted for rotation with the first hinge member. Both hinge members have correspondingly configured engaging surfaces which permit staged rotation between the hinge members. This facilitates a staged rotation of the barrier member in predetermined sequential increments as determined by the engaging surfaces. This first hinge assembly connects a lower portion of the barrier member to the structural member and is responsible for bearing substantially all of the weight of the barrier member. The invention further comprises at least a second hinge assembly for providing rotational alignment between an upper portion of the barrier member and the structural member.
