Abstract: A personnel guard barrier is combined with a guard rail for protecting machinery and directing traffic. The personal guard barrier is preferably formed of at least one modular unit extending two feet in length. This modular unit includes a vertical stanchion anchored to a guard rail at one end of the vertical stanchion. Polymerized sheathing extends and surrounds this vertical stanchion and has an interior diameter equal to or greater than the outer diameter of the vertical stanchion. The guard rail provided to be used in combination with the personnel guard barrier includes a base and vertical support stanchion preferably fixed to the base. Polymerized sheathing extends the length of the vertical stanchion and also has an interior diameter equal to or greater than the outer diameter of the vertical support stanchion.

Abstract: A safety system which protects the open side of a mezzanine, loading dock or other elevated work area when in use. The safety system is easy to use while requiring only minimal floor space. The safety system comprises two posts, a movable arm having a safety net and associated hardware such that when the safety system is in a first position the opening of the mezzanine or loading dock is substantially covered by the net. When the safety system is in a second position, the arm and net are out of the way, allowing access by workers and machinery to and from the open side. The operation of the safety system from the first position to the second position or vice versa is performed remotely from the open side, thus further reducing the risk of falling.

Abstract: A bracket for supporting a fence rail includes a hollow body having an open-topped cavity and an end wall with a cross-shaped aperture through which a bolt is passed into a fence post. The angularity of the body with respect to the post surface is adjusted by installing one or more tapered spacers between the body and the post. The spacers have nesting bosses and recesses, and offset slots through which the bolt passes. One surface of the end wall has a spherical shape so that the head of the bolt seats flat, regardless of the angularity which has been established.

Abstract: A modular railing including a plurality of upright posts and a plurality of composite hand rails extending between adjacent ones of the upright posts. The composite handrails each include a plastic outer shell and an internal metal reinforcing element extending longitudinally within the plastic shell. A plurality of lower rails extend between adjacent ones of the upright posts and a plurality of composite spindles extend between the lower rails and the handrails. A plurality of brackets couple the handrails and the lower rails with the upright posts. The brackets are adapted to be slipped over end portions of the handrails and over end portions of the lower rails and to be fastened to the upright posts. Preferably the brackets are made of metal and have a shaped opening matching a cross-sectional profile of the handrails to allow the brackets to be slipped over the end portions of the handrails. The brackets include flanges to allow the brackets to be fastened to the upright composite posts with fasteners.

The swivel bracket includes a base member and a body member, and the base member preferably has a flat side configured to be secured against the outer surface of a fence post. The opposite side of the base has a rounded concave depression adapted to receive one end of the bracket body member, the body member having a rounded exterior which fits within said depression. The body member has a hollow chamber therein which is open at a side thereof to receive the end of the rail. The ends of the rail are received in the bracket body chambers through the opening therein and then fixed to the brackets.

Abstract: A metallic fence system (10) provides an easily constructed, durable and adaptable system using metal posts (12), cross-pieces (14) between the posts and pickets (20, 30, 40, 50, 60, 70) attached to the cross-pieces (14). Each picket can be either fixed in width (20, 30, 40) or adjustable in width (50, 60, 70). The adjustable pickets can be varied in width to suit a particular need. The pickets can be standard pickets (20, 50) or can be pickets (30, 40, 60, 70) with offset portions. Pickets with offset portions can be placed adjacent to each other and the offset portions will overlap to provide a seamless fence.

Abstract: A fence assembly includes modules of two-foot width. The modules are easily assembled in four-module sections to achieve whatever cumulative length of fencing is desired. A module is joined to an adjacent module by insertion of a clip into vertical, T-shaped slots formed in an adjacent module. Sections are anchored in the ground by pipes having downwardly projecting stakes. These pipe and stake assemblies are located concealed within the first and fourth module of each section. Upper and lower horizontal reinforcing members are attached along the sections. Resilient expanding anchors are used to connect the pipes, extensions, and horizontal members, there being alignable bores formed therein which receive these anchors. In one embodiment, intended for use on flat terrain, the lower reinforcing member is extended through and concealed in longitudinal bores extending through each module.

Abstract: The present portable fence is durable, lightweight and easily transported, erected and dismantled. In use, it will collapse upon impact, due to a break away, in the first embodiment, a joint between the fence post and its supporting leg, and in the second embodiment a joint in the supporting leg, yet in both embodiments the fence may be quickly and easily re-erected.

Abstract: A fence for a depressed waterway has a pair of anchor posts normally located on opposite sides of the waterway. At least one ground anchor is positioned between the anchor posts in the bottom of the waterway. A wire fence extends between the anchor posts and over the ground anchor. A vertical post is secured to the wire and is suspended by the wire above the ground anchor. The vertical post has a lower end detachably secured to the ground anchor so that the lower end of the vertical posts will disengage the ground anchor and will tilt on said wires in a downstream direction when encountered by debris under flooded conditions. The method of use of a waterway fence comprises placing opposite fence anchor posts on opposite sides of the waterway. At least one ground anchor is placed in the waterway below the normal vertical plane of the fence to be built. The fence wire extends between the anchor posts and over the waterway.

Abstract: A continuous elongated trench is provided around a prison or military fortification. Parallel plates are provided on opposite side walls. Anti-personnel wires such as razor or barbed wire in concertina form are placed in the bottom or the trench. A light grid with large openings and weakened portions is placed over the trench and is supported on the plates. Anti-personnel explosives in the bottom of the trench and suspended within the trench beneath the grid deter crossing of the trench by persons, vehicles or objects. A covering over the grid blends the trench into the surrounding area.

Abstract: An articulated highway delineator post assembly which includes an elongated, vertically extending indicator support post telescopingly engaged with a resilient slotted tubular sleeve. The support post is connected to the sleeve by a pivot pin assembly allowing pivotal movement of the support post about a horizontal axis to project a portion of the support post through the slot in the sleeve. The slot in the resilient sleeve is dimensioned in relation to the dimension of the support post to continuously resiliently urge the support post toward a vertical position when it has been inclined from the vertical at an acute angle upon pivotation and extension through a portion of the slot. The assembly further includes a ground post extended into the earth and projected at its upper end into one end of the tubular sleeve for supporting the sleeve and the support post above, and in substantially vertical alignment with, the ground post.
