  • Patent number: 10624414
    Abstract: An athletic skate body has an integrated leather vamp main body, a heel accessory piece, multiple strengthening pieces, a tongue, a shoe lining, an inner board, and a sole. The integrated leather vamp main body has a seamless toe box surface portion and a first lateral surface portion and a second lateral surface portion extending rearward from two sides of the toe box surface portion. The first and the second lateral surface portions are sewed with a heel accessory piece and thus a heel portion is formed. With the seamless toe box surface portion, strength of a head portion of the athletic skate body is enhanced, and a vamp base can be cut into shape by automation equipment. Thus, with the plane and integral vamp base attached with multiple strengthening pieces precisely, the manpower is saved and the quality of the athletic skate body is improved.

  • Publication number: 20150250258
    Abstract: A rigid shoe shell of a skate has a heel portion, two quarter portions respectively extending from two opposite sides of the heel portion, and at least one resilient cushion region formed on an upper edge of the rigid shoe shell. In some embodiments each of the at least one resilient cushion region has multiple strips that have an upper distal end being a free end. Since the strips are bendable, the upper edge of the rigid shoe shell resiliently presses against a lower leg of a wearer of the skate without rubbing against the lower leg of the wearer, thereby providing good protection effect.

  • Patent number: 8778251
    Abstract: A method for manufacturing a one-piece shoe shell of a skate with different widths having acts of forming a shoe shell with a rudimentary mold assembly, ejecting the shoe shell from the rudimentary mold assembly and adjusting a width of the sole of the shoe shell before the shoe shell hardens. The sole of the shoe shell has at least one adjusting portion to allow the sole to expand or be compressed. With the acts, each size of the shoe shell needs only one rudimentary mold assembly that has complex structure and high cost to substantially form a basic shape of the shoe shell and multiple shaping molds of different widths that have simple structure and low cost are prepared to further adjust widths of the shoe shell. Consequently, total cost for manufacturing the shoe shell with different widths is effectively lowered.

  • Patent number: 8453350
    Abstract: A combination structure for a shoe shell has a shoe body, a toecap mounted on a front end of the shoe body and at least one connecting part disposed between the shoe body and the toecap. Each of the at least one connecting part has a female connector and a male connector formed respectively on the shoe body and the toecap and is mounted with each other. Connecting the toecap to the shoe body through the at least one connecting part is an improved quick and time saving process. Furthermore, the toecap is attached securely to the shoe body and not easily detached from the shoe body.

  • Publication number: 20130119580
    Abstract: A method for manufacturing a skate shell has acts of providing an expandable sheet, providing a mold assembly, forming the sheet into a three dimensional shape, mounting the shaped sheet around an inner mold, closing the mold assembly, forcing molten plastic material into the mold assembly and opening the mold assembly. The mold assembly has an outer mold and an inner mold to form a mold cavity. The inner mold has a mold block. The sheet has a peripheral rim squeezed by the inner mold and the outer mold when the mold assembly is closed and the peripheral rim of the sheet is positioned onto the mold block with a positioning assembly. The plastic material is injected into the mold cavity and combined with the shaped sheet to make the sheet smoothly bonded to one surface of the skate shell in a three dimensional arrangement.

  • Patent number: 7549185
    Abstract: A method for making a component of boot body for a skating shoe includes a cutting step, a mold-making step, a coating step and a shaping step. The cutting step cuts a flexible sheet to form a base sheet with at least one predetermined coating area. The mold-making step forms a coating mold with at least one coating slot. The coating step applies epoxy resin to the base sheet to form a layer of epoxy resin coating and applies the epoxy resin to the at least one predetermined coating area through the at least one coating slot to integrally form at least one reinforcement on the base sheet. The shaping step heats and pressurizes the base sheet to form a component of a boot body. The at least one reinforcement provides an improved hardness and impact strength to the boot body and keeps a user's foot from injury.

  • Patent number: 7140127
    Abstract: A body for a skate boot includes a sole portion, a toe portion extending from a front end of the sole portion, two upper portions extending from two sides of the sole portion, and a heel portion extending from a rear end of the sole portion. The sole portion, toe portion, upper portions and heel portion are made of fiber laminations constructed by multiple layers of fiber fabrics and epoxy resin by means of hot-pressing in a die. At least one thermoplastic substratum is provided in the fiber laminations at the upper portions and heel portion, and has two sewn portions respectively formed at two distal ends at the upper portions and extending out from the fiber laminations inside the thermoplastic substratum. Thus, the body is light-weight, has good shock resistance, and can cover the user's foot well.

  • Patent number: 7032329
    Abstract: A composite reinforced toecap for a shoe includes multiple composite fiber reinforcement layers and a larger fiber layer laminated between and extending out from the composite fiber reinforcement layers. The fiber layer is made of continuos-strands. The composite fiber reinforcement layers are made of fiber-reinforced-plastic composite materials, are laminated on the fiber layer to form a pre-product toecap. A bonding coating is applied to the fiber layer that extends beyond the composite fiber reinforcement layer to form a binding. The pre-product is cured and has a binding that can be sewn to the sole, upper or tongue of a shoe.
