Device For Attaching Wheel To Axle Patents (Class 301/111.01)
  • Patent number: 11938754
    Abstract: An anti-loosening device for a fastening unit of a motor-vehicle wheel is configured to be coupled with a wheel hub. The anti-loosening device is configured to be arranged within the wheel hub along an axial direction, so that a main axis of the anti-loosening device coincides with the wheel axis. The anti-loosening device includes a gear arranged to cooperate with inner teeth of the wheel hub, an elastic element extending axially with respect to the gear, and a coupling element obtained on a sector of said gear, arranged to receive a corresponding fastening. During assembly of the wheel—hub assembly, the anti-loosening device is arranged to create a compressed configuration, wherein the gear is decoupled with respect to the inner teeth, and is arranged within a cavity portion obtained on the inner surface of the wheel hub, so as to allow rotation of the anti-loosening device around the main axis.

  • Patent number: 10953693
    Abstract: There is described a quick-release arrangement for mounting a bicycle wheel (2) to a hub of a bicycle frame (1) using a single-sided mount. The quick-release arrangement includes a number of levers (12) each movable between a closed position, in which the wheel is retained to the bicycle hub, and an open position in which the wheel is freely removable. A locking ring (21) is mounted to the bicycle wheel and is rotatable between an open position and a locked position. When the locking ring (21) is in the locked position, hooks (24) on the locking ring (21) are engageable with pins (26) mounted on the levers (12), to prevent the levers (12) from moving out of their closed positions. The locking ring (21) may be mounted to a lever cover plate (18) which is fixed to the wheel and arranged so as to partially cover the levers (12) when they are in their closed positions. The lever cover plate (18) may have a window (27) through which an indicator is visible to indicate the position of the locking ring (21).

  • Patent number: 6910742
    Abstract: A journal for coupling a wheel to an axle has a main tubular body portion with a reception space for the axle and a separate locking element. The locking element is mounted in a cradle for pivotal movement about a pivot axis from a release position in which the axle is removable from the reception space to a position in which the axle is secured in position is the reception space. A biasing member such as a magnet, a spring or a tube of resilient material biases the locking element into the secured position.

  • Patent number: 6910743
    Abstract: A stable wheel assembly has wheels, a connector, a wheel stand with a bracket and a resilient body. Each wheel has a center. The connector has two spindles and two protrusions. Each protrusion has a free end and an upright step integrally formed with the free end of the protrusion. The upright steps on the protrusions are mated with each other. The bracket is pivotally mounted on two protrusions with a fastener. When the scooter or electric motorcycle mounted the stable wheel assembly run on an uneven surface, the wheels is raised up and the protrusion connected to the raised wheels is pivoted around the fastener mounted inside the protrusion and bracket. Therefore, a scooter or an electric motorcycle with the stable wheel assembly can be prevented from turning over.

  • Patent number: 6854812
    Abstract: Disclosed herein is a device for mounting a wheel to the tubular frame of a small appliance. The device includes a sleeve having an elongated body with a proximal end, a distal end, a channel running through the sleeve. A flange extends radially outwardly from the proximal end of the sleeve and a detent on the sleeve is spaced from the flange in the direction of the distal end of the sleeve. A mouth in the sleeve enables the detent to flex inwardly in response to pressure applied radially inwardly against the detent. There is a head at the distal end of the sleeve and a neck connecting the head to the elongated body of the sleeve. The device also includes an axle having an elongated body and opposing ends, with a hub on one end and a nose on the other end. A joint connects the nose to the body of the axle, and the joint is shaped to mate with the neck of the sleeve to lock the axle against axial movement relative to the sleeve.

  • Publication number: 20040262984
    Abstract: A plastic wheel assembly (122, 222) and wheel mounting sleeve (127, 227) used to releasably secure the wheel (122, 222) onto an axle (123, 223). The wheel mounting sleeve (127, 227) includes an axle stabilizing opening (100, 200) positioned in an end wall (158, 258) of the sleeve which receives an axle outer end or axle stub (199, 299) that supports the axle (123, 223) against lateral loading and stabilizes it to reduce wobble, chatter and vibration. The opening (100, 200) permits visual confirmation of proper section of the axle outer end (199, 299) in the opening (100, 200). A universal axle (223, 223a) is also provided which can be used to couple wheels (122, 222) having shaped axle bores (139, 239) to the axle using wheel mounting sleeves (127, 227), as well as being used to couple wheels (420), having straight or substantially cylindrical bores (439), to the axle using conventional fasteners (450, 461, 470).

    Abstract: A quick release detachable wheel hub assembly is shown for a lightweight manual wheelchair. The wheelchair wheels mount on exterior hubs and rotate therewith. The inner face out of each of the exterior hubs mates with an opposing outer face of interior hubs. One of the opposing faces on the hubs has a projection or a plurality of projections which fit snugly into corresponding openings on the opposing face of the other hub when the opposing faces of the hubs are mated. The interior hubs are mounted and rotate on detachable axles which screw into the wheelchair frame. A quick release, removable locking pin is inserted through the center of the hubs and into detachable axle and locked in place and thereby causing the hubs to be locked and rotate together. The wheels are quickly detached by simply removing the locking pins and pulling apart the hubs.

  • Patent number: 6682152
    Abstract: A wheelchair wheel locking system reduces the likelihood that a wheel will inadvertently disengage from the wheelchair. An axle is attached to the wheel and has a protrusion for engaging annular grooves within a wall forming an inner passage through an axle receptor attached to the wheelchair. The axle is inserted in an axial direction into the inner passage and has a first locked position in which the axle is fully engaged with the axle receptor, and a second locked position in which the axle is partially engaged with the axle receptor. If a quick release lock is inadvertently released by, for example, pressing a release button, the protrusion retracts and disengages from a first annular groove within the wall of the axle receptor, the axle may start to move axially relative to the axle receptor to a position in which the wheel will disengage from the wheelchair.
