Abstract: A modular fence unit provides a rigid frame supporting flexible and resilient sheet plastic that is stretched over and secured to the frame to create a visually open, yet resilient barrier. Each modular unit is provided with a connector for joining together one or more juxtaposed modular units or for attachment to an available stationary fixture such as a wall. The connectors may permit junctions between units in freely selectable angled relationships. Connections may be hinged, while others may provide a releasable latch, allowing a modular unit to serve as an access gate.

Abstract: A dasher board system for providing a surrounding barrier for the playing surface of a hockey rink. The dasher board system includes lower dasher board sections and extended continuous transparent upper shielding elements. The lower dasher board sections are formed by pultrusion. This gives the dasher board sections a high concentration of fiberglass and a high strength-to-weight ratio. This enables the sections to be made in longer lengths and reduces assembly time. The dasher board sections include horizontal ribs formed therein during the pultrusion process. A mounting system includes supports that are mounted to the horizontal ribs to stabilize the dasher board sections. Curved dasher board sections are formed by cutting the horizontal ribs and flexing the dasher board sections in the regions of the cuts. The transparent upper shielding is formed from by unrolling an elongated length of relatively thin polycarbonate material.

Further included is a plurality of interconnects adapted to be removably situated within the slots of adjacent wall sections to maintain the lateral relationship thereof. The interconnects include planar interconnects and angled interconnects.

Abstract: A portable fence system including a snow fence panel having a wood frame of 2".times.6" posts bolted together at the corners, with a 4-foot wide strip of plastic snow fence material pulled taut across the center. Each panel is 8 feet long, with a height of 6'-8" or 8'-0", depending upon the application. In both cases the geometry of the frame is optimized for maximum snow trapping efficiency and maximum snow storage, and an opening at the bottom is optimized to eliminate the tendency for snow deposition at the fence. Panels are connected to one another by rebar pins passing through specially designed rotatably mounted U-clips, which also provide attachment to rebar anchors driven into the ground. The U-clip-and-pin connections allow rapid installation and take-down, and add flexibility needed for proper installation in irregular terrain. Panels can be overlapped at either the top or bottom as required to limit space between panels to 11/2", which improves trapping efficiency.
