Abstract:
A zipper puller (110) has a one piece structure including a molded plastic body (112) and an integral molded looped tether (114). The looped tether is molded in a first size and shape, and after molding the looped tether is permanently deformed to a second size and second shape by aligning the crystalline structure of the looped tether material.
Abstract:
Embodiments of the present invention provide a pressure relief assembly that may include a main housing (20) having an air passage chamber (22), and a flapper (34) positioned on or within the air passage chamber. The flapper includes a membrane flap (52) and a stabilizing member (48) extending toward a center of the membrane flap. The stabilizing member prevents the center of said membrane flap from flapping open, but allows outer free edges of the membrane flap to open when air flow at a particular pressure is exerted into said membrane flap from an opening direction.
Abstract:
A safety harness connectable between a user and a fixed object comprising an energy absorbing element, and straps that connect between the energy absorbing element, the user and a fixed base. The energy absorbing element comprises a molded polymeric block having tensile strength and elongation properties to absorb energy. It is a block of polymeric material designed to take advantage of a proprietary process that orients the crystalline structure of the device which increases tensile strength and add elasticity required to absorb fall energy. In one form a slack portion limits elongation of the energy absorbing element.
Abstract:
A device is configured to adjustably retain at least one strap and dampen forces exerted into or by the at least one strap. The device includes a main body including at least one strap adjustment channel configured to adjustably retain the at least one strap, and at least one tensile member formed on or within the main body. The at least one tensile member is configured to flex, bend, and/or stretch in order to absorb the forces exerted into or by the at least one strap.

A safety harness (21) connectable between a user and a fixed object comprising an energy absorbing element (212), and straps that connect between the energy absorbing element, the user and a fixed base. The energy absorbing element comprises a molded polymeric block having tensile strength and elongation properties to absorb energy. It is a block of polymeric material designed to take advantage of a proprietary process that orients the crystalline structure of the device which increases tensile strength and add elasticity required to absorb fall energy. In one form a slack portion (217) limits elongation of the energy absorbing element (212).
Abstract:
A device (20) is configured to adjustably retain at least one strap (40) and dampen forces exerted into or by the at least one strap. The device includes a main body (22) including at least one strap adjustment channel (30) configured to adjustably retain the at least one strap, and at least one tensile member (34) formed on or within the main body. The at least one tensile member is configured to flex, bend, and/or stretch in order to absorb the forces exerted into or by the at least one strap.
Abstract:
A personal equipment suspension system with active support to the lumbar region includes a belt to surround the user's waist and a frame supported on the belt with a resilient membrane of synthetic elastomeric crystalline material in tension on the frame to be interposed between the belt and the user. The frame includes spaced ends and the membrane is a lattice in tension between the spaced ends. In one embodiment, the system is a support belt. In another, it is load bearing such as a backpack configuration. In another, it includes stanchions to support a body armor vest.
Abstract:
A tree-type fastener (10,30,40,55) includes one or more fin stabilizer bases (15,35,45,55) disposed on a shaft of the fastener. When the fastener is subjected to a pull-out force, the fins may be prevented from stacking up, buckling or bending by the fin stabilizer base. The stabilizer base is configured to provide no interference with a work piece when inserted in a work piece aperture. The fastener of the invention provides a high removal force to insertion force ratio and a strong, single piece device. The fastener may also be adapted for modification of new and existing tree-type fasteners.
