  • Patent number: 8794714
    Abstract: A spoked wheel is described that uses flexible spokes having a termination on each end that couple with a rim using nipples. The flexible spokes are supported mid-span by a hub flange cradle that transfers torque from the hub to the rim via two sub-spokes. The hub flange cradle determines whether a sub-spoke is tangential or radial. A plurality of spokes may be used on each side of the wheel.

  • Patent number: 7635170
    Abstract: A spoked wheel comprises a rim, a hub, V-shaped spokes, nipples, and eyelets. There is true pairing of the spokes, because the rim has half the number of spoke attachments as there are nipples. True paired spoking means that there are no side wobble forces or rim twist caused by spoke tension. The rim has spoke attachment holes that are parallel to the axis of wheel rotation and are reinforced with eyelets. The rim has unnecessary material cut away between the spoke attachment holes. To ease adjustment, the nipples are located about midway between the hub and the rim. The hub has longitudinal ribs and that are aligned with each other. That allows the hub body to be machined from a relatively lightweight extrusion. To increase the wheel strength, the inboard spokes are moved outboard as much as possible. The hub has pairs of nipple attachment holes where each pair is located on a diagonal relative to the axis of the hub.

  • Patent number: 5882087
    Abstract: An axle for in-line roller wheels allowing quick release of the wheels and axle from the in-line skate blade frame. The axle is constructed and arranged to allow the distal ends of the axle to move longitudinally relative to each other. There is a spring or other such mechanism forcing the ends of the axle into the openings in the blade frame. The ends of the axle that protrude into the frame are designed not to protrude beyond the outer sides of the frame structure so that the ends of the axle are not subject to wear. The present invention provides for an in-line skate axle that is secure and never needs tightening. Since the wheels are retained by springs there are no bolts or threaded connections to become loose. Other types of construction retain the axle and wheel in the blade frame using spring forces in tension rather than compression. In such arrangements the spring is stretched through the axle and the end retainers are pulled into place thereby retaining the axle and wheel to the frame.

  • Patent number: 5362075
    Abstract: A device for protecting the bearings of the in-line roller skates provided in the form of an axle aperture plug. Each axle aperture plug comprises a spacer portion, a transverse axle bore and a protective flange. The spacer portion has an inner bearing surface for engaging the inner race and spacing the outer race from the frame of the in-line skate. The transverse axle bore through the spacer portion permits passage of an axle along the central axis of rotation of the wheel. The transverse axle bore has a cross-sectional diameter allowing the entire length of the axle to be slidably insertable through the transverse axle bore. The protective flange is disposed about the spacer portion and has a surface which extends symmetrically away from the transverse axle bore and terminates in an outer bearing surface adapted for proximate positioning with respect to the outer race of the wheel bearing when the aperture plug is installed in the in-line roller skate.

  • Patent number: 5356209
    Abstract: A two-piece axle bolt for mounting an in-line skate wheel between the spaced side walls of an in-line U-shaped skate frame. The side walls of the U-shaped skate frame have respective outer faces and respective axle receiving and mounting holes extending therethrough. A bolt head receiving counterbore is formed in the outer face of each of the side walls around the hole. The axle bolt includes a pair of shaft components, each having an elongated central axle shaft portion and an enlarged head disposed at one end of the shaft portion. One of the shaft components has a male threaded segment at the other end of the shaft portion and the other shaft component has a female threaded segment at the other end of the shaft portion. The male and female segment are threadably engaged so that the central shaft portions are in axial alignment to thereby present the two-piece axle bolt.

  • Patent number: 5271633
    Abstract: A skate housing assembly for high speed in-line roller skates. There is a frame with a top surface attached to a sole of a skate boot and two descending side skirts having multiple linear transverse bores. A pocket located on the inside surface of each descending skirt surrounding a bore receives a flange from a bearing insert mounted within a skate wheel. A shaft axially mounted through the skirt bores and bearing insert aligns the wheel on the skate housing.

  • Patent number: 5246238
    Abstract: A roller skate wheel is constructed for rolling in both the forward and lateral directions of the skate. A plurality of rollers are mounted on the wheel hub, each roller rotatable about an axis tangential to a circle on the wheel axis. The rollers conform to a second circle on the wheel axis for contact with a skating surface. Application of friction to the rollers controls the resistance to lateral rolling, thus providing a braking action to the skater.

  • Patent number: 5114166
    Abstract: A wheeled board for riding downhill over the ground. The board has a generally flat riding board which is supported by four wheels through carriage assemblies. The carriage assemblies are held to the board through springs and supported so that when the board is tilted to the right, the front axle will turn in a clockwise manner, and the rear axle will turn in a counter-clockwise manner as viewed from above thereby causing the board to turn to the right. Conversely, when the board is tilted to the left, the front axle will turn counter-clockwise and the rear axle will turn clockwise causing the board to turn to the left. The wheels of the board have a diameter of between four and eight inches and a width of between three and nine inches.

  • Patent number: 5069462
    Abstract: The skate includes an under-frame (3) equipped with two or several rollers aligned one behind the other in a common median plane. Each roller (4, 5) has a shape of a narrow-bobbin, with two circular flanges provided with bands and a central hollowed hub, fixed inside a ball-bearing. This bearing is put in an orifice of a central plate (24) of the under-frame, this plate holding also a front buffer-stop (6) and a back buffer-stop (7). An instrument absorbing the shocks in the radial direction is intercalated between the bearing and the plate (24). Preferably, the under-frame (3) of the skate is equipped with a support for a leg (1) which is articulated in relation to a transverse axis (Y) at the level of the ankle. A braking mechanism of the rollers (4, 5) can be fixed on the central plate (24) of the under-frame. Thanks to the special shape of the rollers, bearings and the under-frame are lightened.

  • Patent number: 5048848
    Abstract: An in-line roller skate utilizes dual position, eccentric axle aperture plugs which are received in the axle apertures of the skate frame to allow mounting of the skate's wheels in either of two distinct orientations. The plugs also solve a serious assembly problem by allowing wheels to be installed in the skate frame without the alignment problems previously encountered between frames, wheels and hard to handle spacing washers.

  • Patent number: 5028058
    Abstract: An in-line roller skate includes a new lightweight frame and brake of synthetic material and embodies structurally interacting components which cooperate to counter and absorb the strain and shock of road bumps and vibration encountered at high speeds by heavy riders and which have in the past required heavy, metal frames. An improved wheel hub solves the problem of overheating bearings and wheel melting encountered by earlier skates and permits prolonged, high speed use of the skates on nonlevel riding surfaces by even heavy skaters under hot road surface conditions.

  • Patent number: 4935643
    Abstract: In a hair treatment device with a winding mandrel driven by a motor and used to wind up hair, the current used by the motor is led through a current limiter circuit in order to limit torque. The current limiter circuit comprises an operating stage and a safety stage. The safety stage is utilized to limit current if the operating stage fails.
