  • Patent number: 6634656
    Abstract: Roller skates (10) having an improved appearance and function as walking shoes by providing at least one skate wheel (210) that can be pivoted by at least 60 degrees up inside the sole (100) of the skate to facilitate walking, and/or providing a skate with user replaceable, friction operated side brakes (410). Preferred skates have multiple such pivoting wheels coupled by a common, pivoting support arm (230), and provide a mechanism that positions the wheels substantially coplanar with the sole of the skate while in the walking position, and substantially perpendicular to the sole of the skate while in the skating position. It is also preferred that the skate wheels pivot about an axis passing through a portion of the wheels.

  • Patent number: 6629698
    Abstract: The present invention relates to a multifunctional shoe which includes a shoe, a locating part, a sliding device and a locking device. The shoe has a sole provided with at least an accommodation. The locating part is fixed by a fixing member inside the accommodation and is a hollow body with the opening thereof is directed downward, thereby forming a mounting opening at the bottom of the sole. The sliding device contains a wheel and a wheel base. The wheel base corresponds to the locating part in form so that it can be received in the locating part. The locking device is located at the side of the locating part. A lock pin is disposed inside the locking device and is controllable from the outside of the sole to be axially moved. The sliding device is fixed inside the locking device while the small part of the wheel projects from the sole for sliding purpose; moreover, the sliding device can be stored or disassembled without projection on the sole for walking purpose.

  • Patent number: 6578930
    Abstract: The “ICE WHEELS” consists of a wheel assembly, which permits interchange with in-line skate wheels for use on ice that reduces weight and or the rolling resistance on ice while the wheel is perpendicular to the ice. The wheel consists of a lightweight hub, bearing accommodating counterbores and an outer ring containing multiple ice-engaging structures and relief grooves. The ice-engaging structures comprise of an outer circumferential contact means, inner circumferential contact means, a new medial circumferential contact means and multiple support surfaces. A new feature of this invention is the elimination of one or both of the inner circumferential contact means penetration into the ice while the wheel is perpendicular to the ice. This leaves either a flat support surface; a flat support surface with one inner circumferential contact means or two support surfaces with a medial circumferential contact means in between while the wheel is perpendicular to the ice.

  • Patent number: 6523836
    Abstract: A wheel assembly for a roller skate. The wheel assembly mainly includes a pivotal seat, a singular locking member and a wheel set. The pivotal seat includes a first end pivotally connected to a sole base by a mounting member for convertibly moving between a stowed position and an extended position and a second end rotatably connected to the wheel set for skating. The singular locking member is adapted to optionally position the pivotal seat either in the stowed position or in the extended position. The singular locking member includes a main plate being adapted to structurally engage with the sole base and two teeth being adapted to lock or unlock the pivotal seat either in the stowed position or in the extended position. The wheel assembly further includes a button being adapted to actuate the singular locking member to unlock the pivotal seat.

  • Patent number: 6481724
    Abstract: The adapter comprises an ice-blade mounted in a blade-chassis. The blade-chassis is a plastic molding, which fits between the support rails of an in-line roller skate, and is clamped therebetween by the spindle-rods that serve as the spindles of the rollers. The ice-blade resides in a channel in the blade-chassis, the roof of the channel, and of the blade, being clear of, and below, the spindle rods.

  • Patent number: 6474661
    Abstract: A base structure for a roller skate includes a base having at least two compartments, a bottom plate secured to the base, and a number of wheel assemblies each of which is mounted in an associated compartment. The bottom plate includes a number of blocks formed on the underside thereof, each block being received in an associated compartment. Each wheel assembly includes a pivotal seat having a first end secured to the underside of the bottom plate, a wheel seat having a first end pivotally connected to a second end of the pivotal seat, and a wheel rotatably mounted to a second end of the wheel seat. Each wheel seat may be pivoted to a storage position in the associated compartment when not in use. When skating is required, each wheel seat is pivoted to an operative position, in which each wheel seat bears against an underside of an associated block while the wheel rotatably attached to each wheel seat extends beyond the base for skating.

  • Patent number: 6464236
    Abstract: A wheel seat assembly of a roller skate includes a sole body fixed on the bottom of a shoe. The sole body is provided with receiving chambers for securing casings therein. The casing defines an axial hole and at least two positioning holes. A roller seat is pivotally mounted in the casing by a pivot member. The pivot member is fitted with a catch member and an elastic member. The catch member may be selectively locked into one of the positioning holes of the casing by an urging action of the elastic member. The roller seat has a roller rotatably mounted therein by a rotation shaft.
