  • Patent number: 4949479
    Abstract: A ski boot comprises a rigid outer shell and an inner shell which is relatively flexible. The inner shell features a relatively flexible saddle region which extends over the metatarsal and/or instep portions of a wearer's foot. Tensile elements, such as cables or straps, extend over the saddle and cooperate with buckle mechanisms to provide a variable supporting force to the wearer's foot. The inner shell also comprises an ankle support structure which grasps the wearer's leg at a point just above the malleolus and cooperates with the heel spoiler to maintain the wearer's heel in contact with the sole of the boot.In another embodiment the ski boot features a hinged inner sole. The inner sole is secured to the outer shell in the phalanx region of the sole, and also is hingedly connected to the heel spoiler in the heel region of the inner sole. A hinge, either mechanical or natural, is disposed adjacent to or in common with the fastening point.

  • Patent number: 4920665
    Abstract: A ski boot minimizes torsional rotation of the foot while permitting bending movement about the ball of the foot. The ski boot includes a toe portion connected to a heel portion by a hinge structure that prohibits torsional movement therebetween. A heel bracket is connected to and pivots with respect to the toe portion independently of the heel portion. The toe portion has a forward tip that may engage a front ski binding, and the heel bracket has a heel member that may engage a rear ski binding. The heel portion may be releasably fastened to the heel bracket for alpine skiing and walking or released for nordic skiing. Hyperextension and hyperflexion limit stops are provided. Extension linkage may be implemented to space the toe and heel portions.

  • Patent number: 4897940
    Abstract: The present invention relates to a rear-entry ski boot having a heel securing device and a shell to which at least one rear quarter is articulated. The peculiarity of the invention resides in that it comprises at least one wedge-like element interposed, at the skier's heel region, between the rear inner surface of said rear quarter and the skier's foot. Means actuatable by the skier are furthermore associated with the wedge-like element for its adjustment. The wedge-like element advantageously acts at a flap protruding from said shell or from a shoe internal to said boot.

  • Patent number: 4872272
    Abstract: The invention concerns a device for detachably fastening a ski boot to a ski binding fixable on the ski, the ski boot comprising a hook element extending in its longitudinal direction. In manner known per se the hook element consists of a wire material which is bent several times and of which the cross rod is located at a distance from the front ski boot end, and where legs joining the cross rod are anchored by bent, free wire segments in the front end of the ski boot sole. In the invention, the free wire segments (6,7) of each leg (4,5) of the hook element (2) are additionally bent by an angle (alpha) toward the cross rod (3), whereby improved anchoring of the hook element (2) and improved force spreading between the hook element and the ski boot (1) is achieved. In further essence of the invention, the individual legs (4,5) are divided into at least three wire segments assuming directions deviating from the preceding and/or following wire segments.

  • Patent number: 4870761
    Abstract: The shoe construction generally includes a closure component having a set of interleaved, opposed stretchable fingers, and a stretchable cord securing the ends of the fingers together. The fingers are composed of stretchable material to grip the foot in a yieldable manner. Such a shoe construction and closure component is comfortable, due to the stretchable cord and fingers which expand during walking or running. Moreover, the resilient and stretchable closure component of the present invention, at the same time, aslo fits snugly against the upper contours of the foot to provide a new form of comfortable support. At the same time, in some forms of the novel construction of the present invention, it can be slipped on or off the foot, without undoing, or otherwise altering the closure component.

  • Patent number: 4837884
    Abstract: Process for filling with foam an inner boot of skiing boot in which the foam or the material to be expanded into a foam is introduced in the lower boot region. The foam or material is directed from the instep region towards the lower heel end and is thus introduced into the skiing boot until it emerges from the heel end. This causes the lateral front region of the inner boot to be filled with foam asymmetrically in relation to the longitudinal central plane.

  • Patent number: 4825564
    Abstract: A temporary covering for feet in cold and wet weather conditions is formed by two identical boots each having a pair of foot shaped plastics members sealed together along substantially their entire periphery leaving only foot entry openings. Together the side members define a sole for the boot. Each boot has at least one tie loop with a tie ribbon passing therethrough. Each boot also has an insert member of generally foot shape received in the boot and which, when rotated to lie generally against the sole portion of the boot shapes the boot into wearable condition. Each boot has a plurality of antiskid strips adhered to the bottom outer surface of the sole portion.

  • Patent number: 4811502
    Abstract: A flexible-type sport shoe, such as a golf or cross country ski shoe, comprising on the inside three flexible ties (16, 17, 18) to secure the user's foot. One (18) of the ties has two ends (19 and 20) connecting it to the sole (2) of the shoe (1) behind the level of the metatarsal and in front of the level of the calcaneum, respectively on both sides of the shoe, and comprises a section (29) to bypass the foot by the rear between the lower level of the lower attachment of the Achilles tendon to the calcaneum and the lower level of the malleoli. The two other ties (16, 17) have an end connected to the sole of the shoe, respectively on both sides thereof, crossing above the instep, and are deviated by respective guides held by the first tie (18), to present complementary sections (45, 46) to bypass the instepby the frontwhentheyarefastened together, and thus ensure a securing of the foot to the sole (1) when the three ties (16, 17 18) are tightened.

  • Patent number: 4761899
    Abstract: The boot comprises an upper (4) hinged (5) with a shell (1). A mechanism allows the upper to be locked to the shell or to be pivoted. This mechanism consists of two links (7, 8) hinged with each other and, on the one hand, with the shell (10) and, on the other hand, with the upper (11). The pin (9) hingeably connecting the links together is accommodated, on the one hand, inside a notch (19b) in the top link (8) and, on the other hand, in a fixed oblong aperture (16). The notch (19b) leads into an oblong aperture (19a) in the top link (8). The mechanism is kept in this locked position by a spring (26). A lever (27) enables the oblong aperture (19a) to be brought opposite the hinging point (9) so that this pin is able to slide inside the superimposed apertures (16, 19a).

  • Patent number: 4750414
    Abstract: A poultry roasting assembly and a method of making same for suspending a bird horizontally over a pan of water by a spit rod inserted under the back bone. The assembly includes a first U-shaped member (14) having a pair of parallel arms (16) extending out from a base section (18). The parallel arms (16) extend in the same direction perpendicularly from opposite ends of the base section (18). A second U-shaped member (20) is included and has the same configuration as the first U-shaped member (14) but with shorter arms (16). A pivot pin (38) pivotally attaches the first U-shaped member (14) to the second U-shaped member (20) at a point (22) spaced from the distal ends (24) of each of the parallel arms (16) so that the distal ends (24) of the arms (16) form a V-shaped configuration (26) above the pivotal attachment (22) when the base sections (16) are pivoted apart, thereby forming a support structure for the spit rod.
