An automatic door stopping-closing device comprises a cylinder with a connecting rod, one end of which is connected to a door; a bracket assembly on the door frame, comprising a hook connected with the other end of the rod, a movable lug cooperated with the hook, and a pull rod cooperated with the movable lug, wherein the pull rod and the hook can be engaged or disengaged. After the door is opened, the door can be kept open securely through the cooperation between the hook and the movable lug; and the door can be closed automatically by a slight push, through the cooperation between two of the hook, the movable lug and the pull rod. The automatic door stopping-closing device holds the door open without external force after the door is opened, and closes the door automatically after a slight push.

A roof support system includes a support member configured to be mounted between a roof panel and a frame of an enclosure. The support member is movable to an extended position that supports the roof panel in an open position. A cam lock mechanism is operatively connected to the support member for releasably locking the support member in the extended position. In the extended position, a pin of the support member is received within a slot of the cam lock mechanism such that engagement of the pin with a closed end of the slot prevents the support member from moving from the extended position toward a retracted position. The cam lock mechanism includes a cam configured to rotate to a locking position that at least partially blocks an open end of the slot such that the pin of the support member is prevented from backing out of the slot.

A display case including a frame with a first fastener, a door with a second fastener, and a bracket coupling the door to the frame is described. The bracket has a first end coupled a second end. The first end is pivotably coupled to the frame by the first fastener. The first end includes a first pair of spring arms having a first slot to couple to the first fastener and to allow the door to pivot between open and closed positions. The second end is slideably coupled to the door by the second fastener. The second end has detents on a second pair of spring arms and a second slot to allow the second fastener of the door to slide as the door is pivoted between open and closed positions. A first detent is positioned further from the first end of the bracket than a second detent.

A device holds a floor of a vehicle in an open position to provide access to an underfloor storage compartment that is covered by the floor when the floor is in a closed position. The device includes a mounting bracket fixed to the vehicle and a support tab pivotally connected to the mounting bracket. The support tab pivots between a first position in the path of the floor and a second position outside of the path of the floor. The support tab pivots in a first direction from the first position to the second position when the floor contacts a bottom surface of the support tab as the floor is raised past the support tab. The support tab automatically returns to the first position. The support tab supports and holds the floor in the open position when the floor is lowered onto the support tab.

A check and release mechanism for holding a door in a desired opened position against the force of a closing cylinder which is separate but alongside a door closing actuator which acts to close the door upon its release, the catch and release mechanism includes a catch and release operator rod separate from an actuator operator rod and parallel thereto moved, the door catch and release operating rod has a latch element pivotally mounted to one side of the catch and release operator rod and is moved along a guide slot in a catch and release mechanism case, by continued opening movement of the door into an enlarged engagement chamber in the case, and the leading end of the latch element engages a first fixed feature therein at the approximate location where it is desired to hold the door open. That engagement causes a slight tilting of the latch element and stops further opening advance of the door and operating rod. A slight retraction of the door and the catch and release operating rod causes a trailing end of the tilted latch element to engage a second fixed feature in the chamber which causes the latch element to tilt further in the same direction preventing further closing movement of the door. The engagement of the latch element with the second fixed feature is released by manually moving the door back in the opening direction, causing one side of the tilted latch element to engage the first fixed feature to tilt the latch element further, and upon release the door again moves in the closing direction and the opposite side of the latch element then contacts the second fixed feature be pivoted so as to again be in alignment with the guide slot, allowing the door to close with the latch element advancing down the guide slot.

An automatic door stopping-closing device comprises a cylinder with a connecting rod, one end of which is connected to a door; a bracket assembly on the door frame, comprising a hook connected with the other end of the rod, a movable lug cooperated with the hook, and a pull rod cooperated with the movable lug, wherein the pull rod and the hook can be engaged or disengaged. After the door is opened, the door can be kept open securely through the cooperation between the hook and the movable lug; and the door can be closed automatically by a slight push, through the cooperation between two of the hook, the movable lug and the pull rod. The automatic door stopping-closing device holds the door open without external force after the door is opened, and closes the door automatically after a slight push.

An assembly has a liftable lid and a movable hinge module. The assembly includes an object having an opening, a lid rotatably arranged upon the opening, and a hinge module. The hinge module includes at least a shaft connected to the lid, a base, and at least a latch. The shaft is connected to the base and along with the base defines a rotating axis. The rotating axis is movably arranged between a close position and an open position. The latch fastens the lid over the opening. When the rotating axis is at close position, the lid closes upon the opening as a close state. When the rotating axis moves away from close position, the lid rotates and moves away from the opening to an open state. The rotating axis moves to open position.
