This application relates to a wheel steering angle adjustment device for a vehicle operated by manpower. The device may include a fixed body including a rotation support, a rotation body, a lift member coupled to the rotation support, a locking switch coupled to the lift member, and a plurality of fixing groove portions in the outer peripheral surface of the rotation support. The device may also include a fixing protrusion protruding from the locking switch and configured to be detachably coupled to the fixing groove portions, a rotation range limiting stopper provided on a lower portion of the lift member, and a rotation guide groove portion provided concavely in an upper surface of the rotation body. As the rotation range limiting stopper becomes stuck on an end portion of the rotation guide groove portion, an angle by which the rotation body is rotatable relative to the fixed body is limited.

Multi-mode auxiliary wheel system adapted for rolling a folded bike, comprising: an upper frame member, at least one supporting side frame member attached to the upper frame member and adapted for attachment to the foldable bike so that the upper frame member is positioned adjacent an upper portion of the rear wheel during an unfolded, ridable, condition of the bike, but adjacent a lower portion of the rear wheel and the ground during a folded, non-ridable, condition of the bike. Lateral and transverse attachment, detachment, and displacement, of the axle, whether horizontal pivotable displacement or not, are provided for with an axle member with auxiliary wheels thereon such that, together with a swivel caster auxiliary wheel, the system enables a user to wheel the bike when in a folded condition, in either a luggage cart type auxiliary wheeling mode or a shopping cart type wheeling mode.

A trailer includes a set of removable castor wheels attached to a rear portion thereof, wherein the castor wheels are oriented to face rearwardly when the trailer is oriented in the traditional horizontal position. This arrangement allows the trailer to be tilted upwardly into a vertical orientation so that it rests on the castor wheels, thus providing an apparatus and method for easily moving and storing trailers more efficiently due to the reduced footprint required for such trailer storage. The castor wheels, in one embodiment, include mounting brackets that may be attached to the trailer using a securing rod, similarly to the mounting mechanisms commonly used for removably attaching trailer hitches into trailer hitch sleeves, thus rendering the castor wheels removable from the trailer when they are not in use for storage purposes.

A low profile wheel assembly suitable for use in dollies, decks or any other platform designed for moving freight or other heavy items. It includes a wheel, a carriage on which the wheel bracket is mounted for rotation about a first axis. The wheel carriage unit fits inside an outer housing unit of this wheel assembly and by means of low friction between the wheel carriage unit and the outer housing unit enabling the wheels carriage unit to rotate concentrically while inside the outer housing unit at a different axis than the first. In this manner and at the same time that the wheel is rolling on a surface, it can change directions of where it is rolling to.

A housing unit for a caster assembly comprising a hollow housing body forming an inner cavity. A first bearing is connected to the hollow housing body, the first bearing defining a rotational axis through its center, and configured to rotatably support a first portion of a stem supporting a caster for rotation about the rotational axis. A support assembly is connected to the hollow housing body, the support assembly being spaced from the first bearing, the support assembly having bearing segments concurrently defining a plain bearing around the rotational axis, the plain bearing configured to rotatably support a second portion of the stem during rotation about the rotational axis. A pressure-applying component is operatively mounted to the support assembly, the pressure-applying component being selectively displaceable to displace the at least one of the bearing segments toward or away from the second portion of the stem, to increase or decrease a pressure of the bearing segments on the second portion of the stem. The support assembly and the first bearing are configured to rotatably support the stem of the caster to form a swivel joint.

A wheel adapter to convert a storage container to a wheeled storage container is provided. The wheel adapter comprises a mounting bracket attachable to the storage container. The mounting bracket comprises a first leg configured to engage a bottom surface of the storage container, and a second leg configured to engage a side surface of the storage container. The second leg comprises a wheel coupling. The wheel adapter also includes a wheel rotatably connected to the wheel coupling. The wheel is constructed and arranged for rotation about an axis to provide rolling support of the storage container on the ground.

Included is a stabilizer wheel assembly that may assist in stabilizing a medical device during a medical procedure. A medical device may comprise a body; and a plurality of stabilizer wheel assemblies coupled to the body, wherein the stabilizer wheel assemblies each comprise a motor assembly and a stabilization leg, wherein the motor assembly is configured to drive the stabilization leg onto a contact surface to stabilize the body.

The invention refers to a furniture panel assembly (200, 200′ 200″, 200′″) comprising a furniture panel (300, 300′ 300″, 300′″) and a wheelhouse cassette (100, 100′, 100″, 100′″). The furniture panel (300, 300′ 300″, 300′″) has a slot (23) extending in a plane in parallel with and at least partly between the major surfaces of the furniture panel (300, 300′ 300″, 300′″) and the wheelhouse cassette (100, 100″, 100″, 100′″) is positioned in the slot (23). The wheelhouse cassette (100, 100′, 100″, 100′″) comprises a wheelhouse (1; 1′; 1″; 1′″) and a wheel (2) adapted to be inserted into and retainably engage the wheelhouse (1; 1′; 1″; 1′″).

A spacing bar of a wheelchair frame comprising an elongated structural body having a pair of opposite ends, each of the opposite ends having a C-shaped clamp configured for being clamped to respective lateral frame members of the wheelchair frame, wherein the elongated structural body and the C-shaped clamps are integrally made of a monocoque composite construction, and a tightening assembly for each of the C-shaped clamps, the tightening assemblies being arranged in the spacing bar to loosen and tighten the C-shaped clamps to the respective lateral frame members. A wheelchair frame comprising: a pair of lateral frame members configured to support at least a seat, and front and rear wheel units, the lateral frame members each having an elongated frame portion in a seating zone of the wheelchair frame, and a spacing bar having an elongated structural body and a pair of opposite ends, each of the opposite ends having a connector configured for being clamped to a respective one of the lateral frame member of the wheelchair frame, wherein each of the connectors forms a joint with the respective one of the elongated frame portions constraining the spacing bar to movement of the spacing bar axially along the pair of the elongated frame portion, a tightening assembly for each of the connectors, the tightening assemblies being arranged in the spacing bar to loosen and tighten the connectors to block or allow movement of the spacing bar along the pair of the lateral frame members.
