  • Patent number: 6125556
    Abstract: A golf shoe sole comprising ejecting and retracting spikes, the improvement wherein said sole contains a high pressure liquid pump assembly in communication with a plurality of housed cylinder assemblies each of which contain a slidable spike with seal, wherein extreme pressure being exerted upon contained liquid equals extreme firmness of ejected spikes. Said pump having shifting means of a four way rotatory spool valve for the control of ejection and retraction in either auto or manual mode, or said pump being one of the two, the former manual operating by way of lever reciprocating upon a piston. The latter auto, operating by way of a diaphragm located on the bottom soul of the back of the heel. Said diaphragm being subject to intense momentary pressure generated by the weight transference from the forward walking motion of the human wearer. An exclusively manual pump requiring only a two way ball, seat, and stem control valve.

  • Patent number: 6115945
    Abstract: A construction for a shoe, particularly an athletic shoe, which includes a sole that conforms to the natural shape of the foot shoe, including the bottom and the sides, when that foot sole deforms naturally by flattening under load while walking or running in order to provide a stable support base for the foot and ankle. Deformation sipes such as slits or channels are introduced in the shoe sole along its long axis, and other axes, to provide it with flexibility roughly equivalent to that of the foot. The result is a shoe sole that accurately parallels the frontal plane deformation of the foot sole, which creates a stable base that is wide and flat even when tilted sideways in extreme pronation or supination motion. In marked contrast, conventional shoe soles are rigid and become highly unstable when tilted sideways because they are supported only by a thin bottom edge.

  • Patent number: 6061931
    Abstract: By analyzing the force which acts during actual running from a bio mechanical perspective and determining the most preferable positions of spikes on the shoe sole, spikes can be arrayed only in necessary positions and not in unnecessary positions so as to further lessen weight and also provide rigidity to the region wherein spike placement is voided, so as to deal with unwanted flexion of the shoe sole. A shoe sole for spiked track-and-field athletic shoes has spikes located only in positions corresponding to the heads of the metatarsals and in positions corresponding to the distal phalanxes. The shoe sole regions between the spikes arrayed in positions corresponding to the heads of the metatarsals and in positions corresponding to the distal phalanxes are provided with an appropriate rigidity.

  • Patent number: 5673472
    Abstract: The present invention is a method of making a molded part having a sheet metal portion and at lease one fastener coupled to the sheet metal portion. The fastener has a body portion and an annular barrel portion which extends from the body portion. The body portion has a free open end and a bore extending therethrough in generally coaxial alignment with the opening in the barrel portion. The barrel portion free end is driven into the sheet metal to pierce the sheet metal and form a slug from the sheet metal. The barrel is also deformed radially outwardly in mechanical interlocking relation with the panel. The slug which is formed is wedged into the opening of the barrel portion to seal the barrel portion. The sheet metal and barrel portion can then be surrounded with molding material with the slug preventing the molding material from flowing into the bore.

  • Patent number: 5526589
    Abstract: An athletic shoe including a shoe upper and an outsole connected to the shoe upper is provided. The outsole defines a plurality of spike receiving openings therein. A plate is located between the shoe upper and the outsole, and includes a plurality of spikes attached thereto. The plate is movable within the upper between a spike-exposing position whereby the plurality of spikes extend outwardly through respective openings formed in the outsole, and a spike-retracting position. An inflatable bladder is located between the plate and the outsole. When inflated with a fluid, the bladder lifts the plate upwardly into the spike-retracting position, and holds the plate in the spike-retracting position during shoe wear. An exhaust communicates with the bladder for exhausting the fluid contained in the bladder. When the fluid is exhausted, the plate is movable into the spike-exposing position by the weight of the wearer during shoe wear.

  • Patent number: 5505012
    Abstract: The present invention relates to a directionally yieldable cleat assembly attached to an athletic shoe having an upper and a sole with a longitudinal axis. A plurality of spaced cleats are mounted to the sole so that the cleats protrude outwardly from the bottom of the sole. In one embodiment, a bumper is provided between the cleat and the sole for enabling a greater magnitude of deformation or deflection of the cleat in response to a predetermined lateral force imposed upon the cleat in a first laterally inward direction with respect to the longitudinal axis of the shoe than the deformation or deflection of the cleat in response to the same predetermined force imposed on the cleat in direction other than the first lateral direction. Deflection of the cleat is also minimized or eliminated in response to forces imposed on the cleats in a parallel direction to the longitudinal axis of the sole to ensure that traction for the shoe is uncompromised.

  • Patent number: 5485687
    Abstract: An anti-slip attachment device is provided for a shoe having a sole and a vamp, which consists of a plate to fit against the bottom of the sole of the shoe. A component is for mounting the plate in a removable manner against the bottom of the sole of the shoe, so that the plate when mounted will be in a stationary position with respect to the sole. A structure on the bottom of the plate is for preventing the sole of the shoe from slipping on an icy surface.

  • Patent number: 5465507
    Abstract: An integral sole for a shoe includes a base plate, a stabilizing plate, and a heel member. The base plate is made of a cushioning material and includes a lower surface having a footprint embossing which engages a walking surface providing traction and comfort for the user. The stabilizing plate is horizontally located about and surrounding the footprint embossing and is made of a material which is harder than the material of the base plate. The stabilizing plate also engages the walking surface and includes a bridge portion extending outwardly from a toe and ball portion of the footprint embossing to provide lateral stability for the sole. The heel member is located peripherally about a heel portion of the stabilizing plate. The heel member is made of a material which is harder than the material of the stabilizing plate to provide a firm heel stability for the shoe. Preferably, the toe portion of the footprint embossing includes five separate toe-print areas.
