  • Patent number: 11602672
    Abstract: A leg attachment assembly for a stilt device of the type used to support a user above a base surface. The leg attachment assembly has a curvilinearly extending leg band configured to partially surround an upper leg portion of a user's leg. The leg band is attached to a distal end of a support pole using a pair of spacers and associated fasteners. One or more strengthening ribs extend in a lateral direction between contact locations of the spacers. The strengthening ribs extend beyond the spacers to enhance rigidity of the leg band during use. A securement strap can be used to encircle the user's leg and the leg band to attach the stilt to the leg. The strap can be routed between the spacers and over the top surfaces of the strengthening ribs so that, when the strap is tensioned, the ribs prevent slippage or displacement of the strap.

  • Patent number: 8297573
    Abstract: A support and attachment assembly configured for attachment to a substrate structure. The assembly includes a rigid body comprising a front surface, a back surface, and a bottom surface. A hinge flange extends from the front surface, a boss member extends from the bottom surface, and a latching member is coupled to the body. The support and attachment assembly is attached to the substrate structure by insertion of the hinge flange into a hinge aperture in the substrate structure. The body is rotated while the hinge flange remains in the hinge aperture to insert the boss member into a boss aperture through the substrate structure and to bring the bottom surface into facing relation with a top surface of the substrate structure. The latching member then contactingly engages the substrate structure to lockingly secure the assembly to the substrate structure.

  • Patent number: 8172730
    Abstract: A stilt device having a front extendible strut and a cooperating rear extendible strut pivotally connected to a base member and a shoe plate, the front and rear extendible struts being disposed in a parallelogram relationship. The rear extendible strut has a rear member and a rear extendible member. A leg support pole is supported at one end by the rear extendible member and extends for its other end to be connected to a workman's leg to provide stability and to thereby enable the replacement of height determining extendible members, the distance from the shoe plate being a common vertical difference that is unchanged the extension of the extendible struts or by components thereof. For stilts of increased height the springs of the damping assemblies are selectively stiffened.

  • Patent number: 7780581
    Abstract: An apparatus attachable to a foot of a user, such as in a leg extension mechanism (stilt device). First and second support members extend from opposing sides of a foot support surface adapted to support the foot. A retention strap has opposing first and second ends each removeably attachable to the support members by the user, preferably by an opposing pair of buckle assemblies. The strap, the support members and the foot support surface maintain the strap in a semi-circular arc nominally symmetric about a centerline of the surface, with the arc having a width greater than a width of the foot support surface to facilitate insertion of the foot between the surface and the strap along the centerline. The support members are preferably slideably adjustable to accommodate different foot widths. A toe guide is also preferably slideably adjustable to align the toes of the foot along the centerline.

  • Patent number: 7744509
    Abstract: Apparatus for enhancing relative rotation between a substrate and a rotatable member. The substrate preferably comprises a pole of a leg support assembly in a stilt device, and the rotatable member preferably comprises a leg engagement assembly of the stilt device which engages a user's leg. The reinforcement member preferably operates as a spacer for the substrate, as well as to reduce wear between the substrate and an elongated member which couples the rotatable member to the substrate. A limit surface of the reinforcement member limits mechanical deflection of the elongated member and preferably comprises an annular sidewall of an aperture. A locking feature of the reinforcement member preferably comprises a tab which engages a channel in the substrate to maintain a desired axial orientation of the reinforcement member.

  • Patent number: 7108640
    Abstract: A stilt device for supporting a user above a base support surface. The stilt device includes a shoe plate, a base member and at least one intermediary strut. A leg attachment assembly comprises an elongated support pole which extends upwardly from the strut. In some embodiments, a clam-shell assembly is attached to a distal end of the support pole and comprises opposing, curved inner and outer plates configured to surround and support the user's leg. A hinge assembly facilitates rotation of the inner plate with respect to the outer plate between open and closed positions. In other embodiments, a support attachment assembly utilizes a u-shaped bracket and a nested, h-shaped clamp to attach the medial portion of the support pole to the shoe plate. The support attachment assembly establishes and secures both the angular extent and length of the support pole.

  • Patent number: 6173660
    Abstract: A retrofit kit formed by pairs of telescoping legs and a tool anchoring platform for a collapsible leg structure for a metal bench including a T-shaped brace rod having one end of its stem pivotally connected to the underside of the bench and its other end extending between and lockingly engaged with the depending end portion of a pair of the legs. A strut, pivotally connected with the stem of the brace rod, is slidably engaged with a track bracket secured to the undersurface of the bench to limit downward movement of the brace rod with respect to the bench. Links connecting the legs to the strut collapse the legs to a folded position under the bench when the brace rod is manually released from the legs and moved toward the undersurface of the bench.

  • Patent number: 5081810
    Abstract: A sandwich-type structural panel is formed by a core of insulating material having opposing skins or face surfaces bonded to opposing planar sides of the core and defining rectangular recesses at each end of the panel.The panel is further characterized by elongated rigid stiffeners extending coextensive with the thickness of the core material and its length between the encapsulating skins.The spacing of the stiffeners is such that a point load of a fixed amount centrally applied to either planar surface or longitudinal edge of the panel generates a load deflection ratio of 1:1 between the central portion of the panel and its respective edge, thus providing a balanced efficient panel.

  • Patent number: 4610056
    Abstract: A belt buckle comprising two unitary plate metal parts, each having an opening for attaching the ends of a belt thereto. One buckle part defines and arcuate tongue, having a part cylindrical recess therein, for receiving a latch bar formed on the other part with the plane of the latch bar inclined to prevent accidental separation of the buckle parts. A belt clamp bar, on the belt part opposite the tongue, grips a doubled back end portion of the belt for adjusting the belt length and tension.
