摘要： A wheel connectable to a vehicle. The wheel includes a stationary member having an axis, a rotary member rotatable about the axis, and at least one support member positioned between the stationary member and the rotary member, thereby providing a normally fixed distance therebetween. The support member is adapted to retain the distance when stressed up to a threshold value and to recoverably alter the distance when stressed over the threshold value.

摘要： A lightweight caster is described that is resistant to ingress of debris into a caster bearing. The caster has a monolithic fork having an annular wheel-supporting portion and a chair-supporting portion. The wheel-supporting portion has a pass-through aperture for receiving a retainer. A rotational bearing is supported on the wheel-supporting portion, which supports a wheel rim such that the wheel rotates in the vertical plane. The rim has a pass-through aperture aligned with the pass-through aperture of the fork, and a ring at an inside edge of the bearing to retain the bearing between the rim and the fork and to inhibit debris from contacting the bearing. A retainer retains the rim on the fork and has an aperture aligned with the fork pass-through aperture. The retainer also has a bearing-retaining portion at an outside edge of the bearing to retain the bearing and to inhibit debris from migrating inwardly.

摘要： A chair is mounted on ball-casters. Each leg of the chair is mounted on a caster wheel that is surrounded by a ring of small metal balls, such as ball bearings, enabling the chair to roll freely without scuffing or scratching the floor or dulling the floor polish, and making it virtually impossible for the occupant to lean back in the chair with any stability.

摘要： A caster mounting assembly for mounting a caster wheel on a wheelchair frame includes a mounting body defining a barrel portion to be fixed relative to the wheelchair frame and a rotatable body within the barrel portion that supports the caster wheel thereon for rotation relative to the rotatable body about an upright caster axis. The caster axis is arranged for rotation together with the rotatable body relative to the mounting body. A locking member is slidable within a channel in the mounting body and includes teeth in meshing engagement with corresponding teeth on the rotatable body. One or more positioning screws permit the locking member to be controllably displaced between longitudinally different locking positions within the channel corresponding to different angular orientations of the caster wheel axis.

摘要： A system for person mobility devices such as wheelchairs. The system includes a personal mobility apparatus having a wheel support portion, and an axle engaging portion that is attachable to and detachable from the wheel support portion. The wheel support portion may be a body portion or a frame portion of the personal mobility apparatus that is formed separately to the wheel support portion. The wheel support portion may be shaped so as to fit a complementary shape of the axle engaging portion. The system allows for customization of a mobility apparatus for a particular application or user by adjusting the position or orientation of the wheel axles.

摘要： A caster-wheel assembly (100; 200) for a vehicle, for example a wheelchair or powered wheelchair. The caster-wheel assembly comprises a switch (13) coupled to a housing (3); a castering wheel bracket (9) configured to receive a wheel (10), wherein the bracket is rotatably mounted about a caster pivot axis (28) with respect to the housing; biasing means (15) configured to provide a biasing force such that the wheel bracket is biased away from the housing; and a switch-actuating member (13) coupled to the wheel bracket such that movement of the wheel bracket towards the housing and against the biasing force causes the switch-actuating member to actuate the switch.

摘要： A connective unit to connect a roller with a seat's leg is disclosed. The connective unit comprises a supportive arm, a plastic cylindrical member, a pivotally connective member and a roller. The plastic cylindrical member may engage with a cylindrical hole provided in the supportive arm. The upper end of the pivotally connective member may engage with a first connective hole and the lower end of the pivotally connective member may engage with a second connective hole of the roller. Thanks to presence of the plastic cylindrical member, when the pivotally connective member rotates and causes the roller to rotate with it, the supportive arm doesn't have any contact with the pivotally connective member and thus noisy friction and impacts between them as in the prior art may be avoided. Therefore, the plastic cylindrical member is difficult to wear out as the pivotally connective member rotates.

摘要： According to the present invention, when a first point (P1) is set on an end edge on an outer end portion (15a) side of a coupling member (15) and a fifth point (P5) is set on an end edge on an inner end portion (15b) side of the coupling member (15), and when a distance (H1) from the fifth point (P5) to the second point (P2) along a reference straight line (RL) passing through the first point (P1) and a tire axis is set to 0.80 times a reference distance (H) from the fifth point (P5) to the first point (P1) along the reference straight line, a distance (H2) from the fifth point (P5) to the third point along the reference straight line is set to 0.65 times the reference distance (H), and a distance (H3) from the fifth point (P5) to the fourth point (P4) along the reference straight line is set to 0.30 times the reference distance (H), the third point (P3) is disposed on the other side in the tire circumferential direction of an overall inclined straight line (SL) passing through the first point (P1) and the fifth point (P5), and a horizontal distance (D2) between the second point (P2) and the third point (P3) in a perpendicular direction (D) perpendicular to the reference straight line (RL) is larger than each of a horizontal distance D1 between the first point (P1) and the second point (P2) in the perpendicular direction (D) and a horizontal distance (D4) between the fourth point (P4) and the fifth point (P5) in the perpendicular direction (D).

摘要： A caster assembly for a wheelchair comprises a stem having a frame clamp at a first end and a fork clamp at a second end, the frame clamp configured to form a frame joint with at least one rotational degree of freedom with a frame portion of the wheelchair, a tightening of the frame clamp securing the stem to the frame portion, the frame joint having a frame rotational axis. A fork unit has a fork portion and a caster rotatably supported by the fork portion, the fork unit having swivel mechanism, and a joint portion forming a rotational joint with the fork clamp of the stem, a tightening of the fork clamp blocking rotation of the rotational joint, the rotational joint having a fork rotational axis. A vector of the fork rotational axis is normal to a fork rotational plane in which the fork rotates relative to the stem, and further wherein the frame rotational axis is not parallel to the fork rotational plane.

摘要： A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.
