A barrier system constructed of modules which includes a frame, a concrete foundation, a frame attached to the concrete foundation and supporting a non-vertical front side plate and a vertical rear side plate so that the front side plate and rear side plate meet at the top and are spread apart from each other at the bottom, slotted connectors on the front side and connectors on the rear side, the module adapted to be joined to an adjacent module either at the same elevation or a different elevation. The modules are joined together via bolts in the rear side connectors and threaded toggle bolts and drop toggle nuts through the front side slotted connectors. Extenders within the slots of the open ended connectors are used when connecting adjacent modules at different elevations to accommodate for slotted connectors of different sizes which must be connected to each other.

A base for a subterranean fence post which includes a body with a ground-engaging surface and a mechanism for mounting a lower end of the fence post to the body wherein a footprint of the surface is sufficient to provide lateral support to maintain the post in an upright orientation and a mass of the body is sufficient to stabilize the upright post.

An exemplary crash gate to guard against motor vehicles crossing a roadway in a direction from an attack side to a protected side including a buttress post assembly secured below ground in a first concrete foundation on a side of the roadway, the buttress post assembly having two buttress posts forming a barrier passage, a latch post assembly secured below the ground in a second concrete foundation on an opposite side of the roadway, the latch post assembly having two latch posts forming a latch gap, a barrier with a gate beam disposed in the barrier passage and extending from a buttress end to a latch end, and one of a vertical pin or a hook connected to the latch post assembly and positioned in the latch gap and the other one of the vertical pin or the hook located on the latch end, when the barrier is in a closed position the latch end is located in the latch gap and the vertical pin is positioned outside of the hook.

A mobile spread-out separating and protecting barrier consisting of air-filled side walls and a base, characterized in that at least two side walls (1) are hinged together in the upper part and connected with at least one plane that constitutes the base (2), wherein the side walls (1) preferably have at least one hole (3)

In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

An accessible passageway assembly is assembled by a plurality of railing units, a plurality of columns, a plurality of step plates and slope guide plates; specifically, the plurality of railing units are spaced by columns to form inner fences and outer fences of the passageway. A support bar is positioned between the lower end of columns of the inner fences and the lower end of columns of the outer fences. A platen is disposed above the support bar. The rear and front end of the support bar and the platen include an extending tongue piece respectively for fast snap-fit of the step plate and the slope guide plate of the passageway. The connection part of the railing unit and the column can be a movable hinge, such that the angle of the railing unit can be adjusted according to the passageway height difference and change, such that the accessible passageway can be quickly assembled and disassembled indoors or outdoors.

Barricade systems are provided. A barricade system includes a first handle recess, a first channel extending to the first handle recess, a first handle portion including a first handle and a first handle post, and a first leg portion including a first leg and a first leg post. The first handle extends perpendicularly from one end of the first handle post. The first leg extends perpendicularly from one end of the first leg post. The first handle post and the first leg post are rotatably connected to each other. The rotatably connected first handle post and first leg post are disposed within the first channel. The barricade system switches between a stowed state and a deployed state by rotating the first handle post 180 degree. The 180 degree rotation of the first handle post facilitates a 90 degree rotation of the first leg post.

A passage control device having a corridor (1) and at least one pedestrian barrier (3), which, by the use of at least one blocking element (5) which is arranged in the region of the corridor (1) and can be moved between a blocking position and a passage position, releases or blocks the corridor (1) for a passage. Lateral boundaries (2) are arranged right and left of the corridor (1). The lateral boundaries (2) have a module rail (6) that is close to the ground and is provided with receptacles for functional elements and/or functional modules of the access control device, more particularly with specifically adapted receptacles for functional elements and/or functional modules of the access control device, preferably in a predefined grid.

A pedestrian gate (3) for an access control device, having a blocking element (7) and having an actuating element (8), wherein the blocking element (7) is fastened to the actuating element (8) and is pivotable via the actuating element (8) about a vertical axis of rotation (11) between a blocking position and an access position. The blocking element (7) is, in a vertical projection, formed so as to run substantially rectilinearly and, here, defines a vertical blocking plane (12) which does not include the axis of rotation (11).

Embodiments of the present disclosure are directed to an attraction system that includes a walkway, a carrier disposed at a first side of the walkway, and a barrier disposed at a second side of the walkway opposite the first side. The carrier is configured to translate relative to the walkway, and the barrier is removably coupled to the carrier. Translation of the carrier relative to the walkway transitions the barrier between a stowed configuration and a deployed configuration.
