A work vehicle includes a pair of left and right pivotal connecting units provided on a front frame, a caster wheel, a caster axle and a caster bracket connected to the pivotal connecting unit. The caster bracket includes side walls supporting the caster axle, a top wall extending rearwards from the upper side of the caster wheel and interconnecting the left side wall and the right side wall, and left and right cover portions for covering gaps between the side walls and the caster wheel.

A system of bracket assemblies for a wheelchair comprises a pair of bracket assemblies adapted to be connected to respective sides of a seat frame of the wheelchair. Each of the bracket assemblies has a base adapted to be secured to a seat frame member of the seat frame, an arm adapted to be secured to a backrest frame member of a backrest frame, and a pivot pivotally connecting the base to the arm for rotational movement of the arm relative to the base. One or more blocking mechanism blocks the rotational movement of the arm relative to the base in a use orientation of the backrest frame. A rod having opposed ends connected to the base of the pair of the bracket assemblies for spacing the bracket assemblies away from one another. A rear wheel unit is also provided.

A tube assembly for a wheelchair frame comprises a tubular member having at least a first portion and a second portion angled relative to the first portion, the first portion configured to be in a seating zone of the wheelchair frame. The second portion is configured to be in a bottom front zone of the wheelchair frame, the tubular member defining a surface concavity in its peripheral surface delimited by a peripheral step, the surface concavity located at a junction between the first portion and the second portion of the tubular member. An interface member has a peripheral contour shaped and sized for the interface member to be received in the surface concavity and contoured at least partially by the peripheral step.

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.

A cart suspension device or system, or a castor equipped cart or platform having such a cart suspension system or device which reduces noise and vibrations when in use. The cart suspension device or system, or castor equipped cart or platform having such a cart suspension system or device utilizes a swing arm or a one-piece spring bracket and a shock pneumatic rubber damper to greatly reduce the noise and vibration inherent in carts rolling over uneven surfaces.

The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having an increased slope, which means a smaller angular slope level, or a more acute inclination angle between the central vertical axis of the device and the surface upon which it rolls. The slope, or inclination angle of the present improved device is from 62 to 50, or less. As the inclinations angle can be more acute, the object supported on the rolling system, e.g. a luggage case, can be more sloped without having friction between the main ball involving structure and the ground.

Luggage with retractable wheels is described, specifically pivoting caster wheels. A telescopic handle is provided on the luggage bag which actuates the retractable wheels using a unique linear mechanism. Pushing the telescopic handle down to the stowed position allows the wheels to retract inside the bag, making the bag easier to stow in the restricted storage space available in the passenger cabin of a commercial aircraft Pulling the telescopic handle out into an extended configuration allows the wheels to deploy into an operable position.

Exemplary aspects of the present invention are directed to a reconfigurable dolly that may include a base, one or more base plates, that may be removable from the base and nest within the base, and one or more caster wheels connected to the base to allow for movement of the reconfigurable dolly relative to the surface on which the reconfigurable dolly may be positioned. The base of the reconfigurable dolly may be configured to be coupled to a base receiving tube. The base receiving tube may be configured for telescoping receipt of a seat receiving tube. The seat receiving tube may be telescopically positionable within the base receiving tube. The seat receiving tube may be configured for receipt and retention of an adjustable seat.

The mount includes a base formed of a substantially planar side wall and a substantially planar bottom wall. The interior surfaces of the walls intersect at a right angle. Each of the walls has an opening. The wall openings together form a recess adapted to receive the wheel. A first notched protrusion extends from the side wall interior surface and is intended to be received in a slot adjacent a cut-out on the side wall of a container on which the mount is installed. A second protrusion, having two portions situated as an angle extends from the bottom wall interior surface of the mount and is intended to be received in a slot adjacent a cut-out on the bottom of the container.
