A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

The motorized drive according to the invention application is configured to open and/or close a wing of a barrier such as a door, main door, gate or swing shutter, a wall or sliding partition or other sliding wing. The motorized drive comprises includes a motor and a first reduction unit through which the motor can open or close the wing. The reduction unit comprises includes a first and a second toothed profile engaging together, thus realizing a gear with a variable transmission ratio depending on the angular and/or linear position of at least one of the two toothed profiles. At least one of the first and of the second toothed profile forms at least one toothed section having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

A passage barrier has first and second guide elements that cooperate to define a gate region, through which a person passes from an entrance region into a passage region. The passage barrier has a drive drive unit. The drive has an output unit including a hollow shaft having an outer shell surface. The hollow shaft has a barrier element mount formed for fixing a plate-shaped barrier element on the hollow shaft and is formed substantially in a U-shape. The barrier element is fixed between the limbs of the barrier element mount, wherein at least two adhesive grooves are provided on the inside at the base of the barrier element mount. At least two opposing adhesive grooves are provided for receiving an adhesive on the inside on both limbs of the barrier element mount and opposing grooves are formed on the inside at distal ends of the barrier element mount.

A latch mechanism for a gate has a main support, first and second retention members, and a rotatable latch. The retention members each have a respective key aperture and the respective first and second apertures are spaced along the main support and separated by a gap. The rotatable latch includes a latch portion, one or more key portions which extend through either or both of the first key aperture and second key aperture, and is rotatable about an axis of rotation between a receiving position in which the gate is moveable between an open position and a closed position, or vice versa, and a latched position in which the gate is restrained in the closed position by the latch portion and where the one or more key portions engage with either or both of the first and second retention members to prevent withdrawal of the rotatable latch.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

An access control system for restricting access through a passageway includes a shaft rotatable about a central axis; a barrier fixed to the shaft to rotate therewith; and a brake assembly. The brake assembly includes a sun gear rotatable about the central axis, a carrier, and a ring gear, wherein one of the carrier or the ring gear is fixed against rotation and the other of the carrier or ring gear is connected to the shaft to rotate therewith. A plurality of planet gears are rotatably connected to the carrier, each planet gear being disposed between and engaging with each of the sun gear and the ring gear. The armature of an electromagnetic brake comprising an electromagnet and an armature is connected to or integral with the sun gear to rotate therewith. At least one of the electromagnet or the armature is moveable between an operative and an inoperative position.

A gate may generally include a gatepost and a plurality of rails pivotally connected to the gatepost and having a plurality of posts hingedly attached to at least one of the plurality of rails. The gate may include a lift system having a translating device in communication with a sprocket, wherein the lift system provides an adjustable force to rotate the plurality of rails from a horizontal position to an upward position. The adjustable force may be provided by a tumbuckle. The gate may include a ground anchor system that allows axial rotation of the plurality of rails about a longitudinal axis of the gatepost.

A portable barricade includes a road plate, first and second support posts extending upward from end portions of the road plate, a barricade arm extending between the first and second support posts, and a lift coupled one of the end portions of the barricade arm and a corresponding one of the first and second support posts. Actuation of the lift is configured to slide the barricade arm relative to the first and second support members between a retracted position proximate to the road plate and a deployed position distal from the road plate.

A dampened hinge assembly has a male leaf and a female leaf. The female leaf has spaced apart first and second end barrels coaxially rotating with respect to a central barrel of the male leaf therebetween. An axial shaft is fixed to the second end barrel of the female leaf at a proximal end of the axial shaft. The axial shaft has a distal helicoidally threaded spindle. A compression gear having a helicoidally threaded bore matching the helicoidal thread of the spindle displaces towards the first end barrel when the leaves move into alignment and towards the second end barrel when the leaves move out of alignment. The dampened hinge assembly may be reconfigured to provide soft closure, end-of-range soft closure and/or backcheck damping.

A hinge is arranged to move two panels, such as a stationary fence panel and a gate, between an open position and a closed position. When the hinge is in a closed position, the posts to which the hinge is attached are maintained in substantial contact along substantially the entire longitudinal length of the posts, thereby preventing small animals from passing through the fence. The hinge has two hinge halves, each having a finger portion arranged to interlace with a finger portion of the other hinge half, each finger of the finger portions defining an opening, and an arcuate post-engaging portion extending for at least 90 degrees and defining a longitudinal opening for receiving an end post, wherein each longitudinal opening faces the other when the hinge is in a closed position. The hinge also has a hinge pin passing through and within the openings allowing rotation.
