The present lift lock is employed on a gate that is swingable and liftable on a first axis. In a first position the lift lock is on the first axis and in a blocking position that prevents the gate from being lifted relative to a barrier having the gate. The lift lock is slideable away from the first position on the axis to a second position away from the axis where the lift lock is in an unblocking position, thereby permitting the gate to be lifted on the axis. The lift lock snaps into and out of the second position.

A door system includes a track spanning a doorway defined by a trailing jamb and an opposing lead jamb, a sidelite panel coupled to the trailing jamb by a swing clear hinge, and first and second slide panels moveable within the track. The trailing jamb includes a jamb face facing in a first direction. The swing clear hinge includes a fixed portion engaged with a revolving portion. The fixed portion is offset from the jamb face in a second direction and secured by a jamb attachment member to the jamb face. The first and second slide panels have an open configuration in the track with the revolving portion offset from the jamb face in the second direction. The panels are configured to pivot out of the track into a breakout configuration. The sidelite panel is offset from the jamb face in the second direction in the breakout configuration.

Improvements to movable closure systems which aid installability and reliability of said systems can include wheels running along the top and bottom of individual slidable elements, the wheels oriented horizontally and disposed within a track configured for receiving the horizontal wheels. The horizontal wheels reduce the vertical profile of the track-engaging portions of the slidable elements, enabling more of the slidable element to be used for glass or other aesthetically-preferable transparent materials. A track leveling system enables installers to more easily deploy and properly tune the system between floors and casings which are not perfectly flush. A compression jamb permits closure of the system via slidable elements pressing into the jamb to deflect it in order to better seal the closure comprised of the individual slidable elements. A durable hinge mechanism permits the sliding elements to rotate in order to stack the sliding elements at one end of the system.

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.

There is provided a rotatable and hung safety window assembly comprising: a housing having opposite holes defined in opposite inner side walls thereof respectively; a guide chassis disposed in an upper space in the housing, wherein the guide chassis has opposite guide grooved lines defined in opposite inner side walls thereof respectively; a rotatable chassis disposed in a lower space in the housing, wherein the rotatable chassis has opposite hinge protrusions formed on opposite outer side walls thereof to correspond to the opposite holes respectively, wherein the hinge protrusions are hingedly received in the holes respectively; an upper window having opposite guide protrusions formed on opposite outer side walls thereof, wherein the guide protrusions are slidably received in the first guide grooved lines; and a lower window fitted into the rotatable chassis.

A combination door assembly includes a frame that may be coupled to a wall of a building. A door is hingedly coupled to the frame such that the door is positionable between an open position and a closed position. The door comprises a first half that is slidably coupled to a second half. The second half is positionable in an open position when the door is positioned in the closed position. Thus, the second half is configured to allow egress and entry to the building when the door is in the closed position.

The present invention relates to a double breakout sliding door system for use in retail and other buildings. The system includes left and right doors that are configured to slide open and closed and also breakout in two directions (outward and inward) when a force is exerted on the doors in order to, for example, allow customers and employees to exit a building in the event of a fire and to prevent damage to the doors in the event that a user pushes on them when they are closed. The system also includes a leveling system configured to keep the doors level when they breakout and a ball detent mechanism to alert the user to the proper position of the doors.

An actuator opens and closes a lid on a bulk storage container. The actuator may be activated remotely using a remote control. When actuated, the actuator will lift the lid so that it is clear of the structure, and will then rotate the lid in a horizontal plan about a vertical axis until the lid is rotated to uncover the opening. The axis of rotation is located near the perimeter of the opening, so that very little of the lid remains over the opening when in the open position. To close the lid from the open position, the remote control may then in he used to actuate the closing process. The closing process works in reverse of the opening process. Therefore, during closing, the lid will rotate back to its original orientation over the hole and then lower into the closed position.

A closure mechanism for an electromagnetically sealed measuring station, which comprises a test chamber, a door for closing the test chamber, and an electromagnetic seal, which is fitted to a door frame of the test chamber. The door is moved initially in a linear manner away from the test chamber and after that pivoted in a rotating movement. The closure mechanism according to the invention then seals a measuring station electromagnetically if an electromagnetic seal is fitted in a peripheral groove in the doorframe of the test chamber, and the door provides a peripheral rebate, which engages in the groove in the doorframe.
