  • Patent number: 11852177
    Abstract: A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof. The system also uses an anchor which includes a sleeve and a plug. The sleeve includes at least two legs extending toward a first end of the sleeve. The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

  • Patent number: 11215263
    Abstract: A bidirectional, wedge clamp is disclosed. Conventional clamps, such as those used with electrical cables mainly secure a line in a single direction. The invention herein being comprised of a bidirectional clamp for conventional cables, wires and rope etc. (herein referred to as a ‘line’) having a simple and easily-operable construction, wherein two plate-like members and an outer sleeve-like member are telescopically assembled to clamp a line there between. Plates and sleeve members having a plurality of interconnected, opposing number of wedges that when acted upon in a lateral motion by a line there between, causing said wedges to slide against one another—thereby tightening down the plates onto said line and preventing slippage. An object of the invention is to clamp a line and prevent slipping laterally in either direction along the line's longitudinal axis.

  • Patent number: 10480218
    Abstract: A strap for a security device has a core (12,62) within a flexible sleeve (14,64), and the sleeve is extensible independently of the core such that the core is not under tension. Because the core is not under tension, it is more difficult to cut and substantially inhibits, if not prevents, cutting of the sleeve. The core may take various forms which resist cutting in different ways. Examples are elongate, normally metallic planar bodies (12,34,38) having longitudinal flexibility but resistance to lateral flexure, and extensible springs (16,22,26). The sleeve (14,64) can also be designed to complicate any attempt to cut the strap as a whole, and may comprise multiple layers (76,78).
