A gravity gate latch that is sized and configured to be positioned in the gap between the free end of a gate and a stationary object when the end of the gate is adjacent the stationary object to automatically engage a strike member on the gate. The gate latch has a pair of side plates that are spaced apart to define a space that encloses a lever actuating mechanism and a hook plate. The hook plate has a hook member that engages the strike member of the gate. The lever actuating mechanism has a pair of lever arms, which can be accessed from either side of the gate, that move the hook plate upward to disengage the strike member. A lock receiving member at the bottom of the gate latch receives a padlock to lock the gate latch. The padlock can also be accessed from either side of the gate.

A vertically folding barrier gate arm has a proximal first segment and a distal second segment connected by a pivot hinge allowing them to fold. An extension set pivotally affixed to an outer offset bracket on the housing for the motor of the gate arm is connected to an outer offset bracket on the distal gate arm segment by a multi-articulated compound hinge formed by a plurality of links attached to each other by hinges providing a constrained range of rotation relative to each other. The gate arm translates from a fully extended position where the proximal and distal gate arm segments are parallel and co-linear along a horizontal longitudinal axis, to a vertically folded position where the proximal and distal gate arm segments lie substantially against each other within the plane of rotation of the first segment.

A gate made from light weight tubular material with creates a framework upon which slats are attached. Slats are capable of being attached on the front of the gate or being passed through slots in the tubular material. The framework is capable of being reinforced with the use of additional tubular material or braces in the corners, as well as additional horizontal, vertical, or diagonal supports.

A gate hinge assembly for pivotally mounting a gate having longitudinal horizontal members and a leg frame member to a post. Each bracket assembly includes a threaded rod with a nut and washer for securing the rod to a post disposed therebetween The threaded rod including a proximate end including a sleeve mounted perpendicular to the threaded rod. A U-shaped bracket having opposing sidewalls with an open end for receiving a horizontal bar and vertical post of a gate frame includes a pair of spaced apart aligned sleeves mounting on an outside end wall of the bracket. The bracket includes a plurality of spaced apart aligned apertures for insertion of bolts for attachment to a vertical end leg and horizontal member of a gate. The rod sleeve is aligned and inserted between the bracket sleeves pivotally connecting the gate to the post.

A modular guardrail system relates to a set of interconnected beams that each fit into pairs of detachable bases, thus allowing for the creation, adjustment, and removal of a variety of configurations of temporary fence-style barriers. Each guardrail section may include two vertical posts, one on each end of each guardrail section, connected by a set of horizontal beams and, in some cases, a horizontal toeplate. Adjacent guardrail sections share a common base, thus allowing for the chain assembly of an extended barrier. The base that connects to the guardrail sections may include several vertically-oriented brackets that may slide into the different guardrail posts. The placement of the vertical brackets upon the base is selected so that each of the attached guardrail sections can be arranged independently of one another in any direction. The vertical brackets may be rotatably attached, thereby allowing for more flexible arrangements of the guardrail sections.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A gate apparatus having an automatically returning gate, an upper latch operated by an upper button, and a lower latch operated by an upper finger handle. Each of the latches must be opened to open the gate. The gate returns without the aid of a spring to a position close to the closed position or to the closed position by the structure of a pivot or hinge connection between the gate and the frame of the gate. Gate tubes are rectangular in section for their entire length. Wood panels are included in the gate and excluded from other portions of the gate apparatus to make the gate stand out to the user seeking to open the gate.

A mezzanine gate assembly is adapted to provide ingress and egress to an elevated platform while safely preventing falls and injury to workers positioned thereon or even below the mezzanine platform. The mezzanine assembly generally includes a support assembly which has a first and second upright support members. Each of the first and second upright support members has a base portion fixedly attached to the elevated platform and an upper portion which is configured to function as a post adjacent to the respective terminating railing. The mezzanine gate assembly comprises an interior gate assembly and an exterior gate assembly. Generally, each of the interior and exterior gate assemblies are designed to move and pivot through a path of motion which provides a plurality of points of travel. The interior gate assembly is operably designed to engage with and deviate rearward while the load is delivered to the platform via forklift in order to provide a barrier between the respective railing and side of the load. The exterior gate assembly is operably designed to provide a barrier while the load of goods is manually removed from the pallet.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A vehicle barrier system employing a first gate arm having a first continuous side wall with a first channel, a second gate arm slidably insertable into the first gate arm having a second channel, and a third gate arm slidably insertable into the second gate arm with a third channel. A fastener secures the extended gate arms to a desired length. Once extended, an LED light strip is placed through the channels. The light strip can be cut to size as necessary, wherein the length of the gate arm and associated light strip can be adjusted on site to a particular length. A controller is used to pivot the gate arm between a horizontal and vertical position to operate as a vehicle barrier.
