  • Patent number: 6227218
    Abstract: A tent (10) includes a fabric shell (12) supported by a plurality of poles (16). The poles (16) are selectively secured to the fabric shell (12) by a plurality of clips (20). Each clip (20) includes a base (26) that is directly sewn or otherwise secured to the fabric shell (12). Each clip further defines a clasp portion (24) that selectively receives a first pole (16a), and which may also selectively receives a transverse second pole (16b). A width defined by the base (26) is preferably wider than a width defined by the clasp portion (24) for enhanced stability.

  • Patent number: 6195919
    Abstract: The novel snowshoe (400) includes at least one tail extender (404) to provide variable flotation characteristics and traction bars (412) that provide improved side slip protection such as when traversing steep terrain. The snowshoe (400) is thereby especially advantageous for use in back country mountaineering. A three (or more) point attachment mechanism is disclosed for coupling the tail extender (404) to the flotation plate (416) of snowshoe (400) so as to reduce stress on the coupling elements and provide a more secure interface.

  • Patent number: 5330640
    Abstract: A water filter including an inlet assembly which comprises a prefiltering foam tip. The inlet hose includes an adjustable float and a weight on the end of the hose which allows a given length at the end of the inlet hose to extend below the surface of the water being filtered. The water filter further includes a check valve assembly to relieve pressure buildup inside the pump. A unique lever-action handle, in combination with a rocking piston, allows efficient filtering with few moving parts. The filter components are easily replaceable. The main filter assembly is suspended resiliently at its periphery to provide shock-absorbing characteristics. The filter also includes an adaptor base which allows for a direct connect between the vessel into which water is filter. The water filter also provides a unique method of storing the inlet hose to render the water filter easy to carry and prevent foreign objects and debris from entering into the area of working parts.
