Abstract: A door system includes two bi-parting, center-opening, bi-directional door panels disposed for counter-rotating swinging movement in a doorway. An operator is coupled to the door panels via a synchronizing system such that the door panels may be selectively opened in either direction relative to the doorway, and closed in the opposite direction, and such that the door panels swing through substantially equal angular distances. The synchronizing system may include a linkage, among other systems, and the operator may include an electro-mechanical operator, a mechanical door closer with spring, or a hybrid of both. A person may effect an emergency breakout by manually using a single-motion, low-force push against one of the door panels to simultaneously open both door panels.

Abstract: A control mechanism has a means for lifting, a lifting cable, and a lifting cable housing. The means for lifting has a control post, and a lift handle attached to a lift body frame about a lift pivot. The lift body frame extends longitudinally perpendicular from the control post. A hydraulic strut extends between an upper lift pivot and a lower lift pivot. A slide rail extends from a roller housing through the slide rail housing. A roller rests between a roller pin and a set pin within the roller housing. A plurality of spacing sliders straddle the slide rail. Removal of one or more of the spacing sliders allows the roller housing and the slide rail to move towards the lift housing member, thereby allowing rotation of the lift body frame and compression of the hydraulic strut.

Abstract: A self closing enclosed hinge is placed within the tubular structure of a gate. The inventive hidden hinge cannot physically smash fingers. An internal axle physically holds together a first gate hinge connector piece which receives the upper part of the gate, an upper stationary hinge piece, and a midsection outer tubular section, which contains a bushing and a spiral spring to return the gate to a closed position. This internal axle joins the lower stationary hinge piece with the second gate hinge connector piece. The second gate hinge connector piece receives lower part of workpiece gate.

Abstract: A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).

Abstract: A bi-swing gate lock uses an electric actuator to unlatch the gate on request, and a failsafe mode that automatically unlatches the gate during emergencies or power failures. The traplock uses two swing arms that pivot retractable door stops in and out on either side of a closed gate from a stationary 4? post. Loads trying to force open a locked gate are redirected through polyurethane pads on the sides of the retractable door stops directly to the insides of matching pockets within the post. Such loads can flex the swing arms, but significant loads will not reach the swing arm pivot bearings. Keeping the gate locked requires electric power applied to a lock actuator, and the loss of power automatically unlocks the traplock. Power applied to a retraction actuator pushes out the retractable door stops. A sensor detects when the gate returns to a closed position and the lock actuator can be energized once again.
