Self-closing safety gate embodiments are disclosed herein. The self-closing safety gates include a hinge plate configured to rotate about a vertical support member and engage a hoop portion. In some embodiments, the hinge plate includes at least one support arm portion with a channel. In such embodiments, the channel can be configured to receive and frictionally engage a hoop arm of the hoop portion with a compressive fastener. In some embodiments, the self-closing safety gate can be damped.

A sanitary installation is described that comprises at least one sanitary space, which can be closed, and whose pivot door is configured as a double-leaf angled door having a leaf composed of a material that is preferably transparent over its full area and having a leaf composed of an opaque material.

A room access control system including a base assembly positionable adjacent a door opening; an arm having a first end pivotally mounted with respect to the base assembly; wherein the arm is positionable in a first undeployed position where the arm is generally vertical and the second end of the arm points downwardly; wherein a fan assembly is attached to the arm, the fan assembly including a plurality of fan blades; wherein each of the fan blades is pivotally mounted to a pivot point on the arm; wherein when the arm is rotated into a second, generally horizontal deployed position, the plurality of fan blades extend beneath the arm in a fanned out pattern with the second end of a first fan blade of the plurality of fan blades attached to the arm, and a last fan blade of the plurality of fan blades positioned in a generally vertical position.

A room access control system including a base assembly positionable adjacent a door opening; an arm having a first end pivotally mounted with respect to the base assembly; wherein the arm is positionable in a first undeployed position where the arm is generally vertical and the second end of the arm points downwardly; wherein a fan assembly is attached to the arm, the fan assembly including a plurality of fan blades; wherein each of the fan blades is pivotally mounted to a pivot point on the arm; wherein when the arm is rotated into a second, generally horizontal deployed position, the plurality of fan blades extend beneath the arm in a fanned out pattern with the second end of a first fan blade of the plurality of fan blades attached to the arm, and a last fan blade of the plurality of fan blades positioned in a generally vertical position.

A gate system includes a cam sled having a cam plate configured to slide along a rail. The gate system also includes a cam follower engaged with the cam plate and coupled to a gate assembly. Actuation of a power source to move the cam sled along the rail causes the gate assembly to rotate about an axis and mechanically lock into position in open or closed orientations of the gate assembly.

A room access control system including a base attachable to a wall or door jamb adjacent a door opening to a room, an arm having a first end pivotally mounted to the base and having a second end, illuminated warning indicia positioned on the arm, wherein the arm is positionable in a first position wherein the arm is in a generally vertical, undeployed position with the second end of the arm positioned above a floor located beneath the base and adjacent the door opening, and wherein the arm is pivotable from the first, generally vertical undeployed position, to a second generally horizontal, deployed position, where the arm extends across the door opening.

The present invention relates to a gate. More specifically, the present invention relates to a gate having at least one arm, wherein the at least one arm is configured to extend and retract. When the at least one arm is substantially extended, the at least one arm substantially prevents access through the gate. When the at least one arm is substantially retracted, the at least one arm no longer substantially prevents access through the gate.

A pneumatic drive mechanism for converting linear motion from compressed air into rotational motion for use in fare gates and other applications.

An access control device includes a primary access barrier configured move between a closed position and an open position. The primary access barrier may be configured to extend into an access passage of the access control device to prevent access through the access passage when in the closed position and to move away from the access passage to permit access through the access passage when in an open position. An entry access barrier is positionable in the access passage of the access control device on a first side of the primary access barrier, and an exit barrier is positionable in the access passage of the access control device on a second side of the primary access barrier opposite the first side. Systems and methods relate to access control devices.

A turnstile comprising means for dictating a person entering or exiting the lane, a barrier positioned to move between a position blocking a lane and a position where it allows passage through the lane, under control of a motor; means for checking the credentials of a person attempting to pass through the lane and a brake, the turnstile having a mode of operation in which in the event that a user enters an exit side of the lane without presenting a credential, and an authorized person is not detected on the entry side of the lane, the brake is unlocked and the barrier is held in position in a closed mode but is able to be pushed or pulled by the person who has entered from the exit side in order for that person to exit; and the motor assists movement in the pushing or pulling direction by moving the barrier at a controlled speed, less than a speed at which it operates the barrier if the exiting user presents a credential.
