Each wheel may rotate in a plane positioned at an angle to at least one other wheel. Each wheel may be coupled to the support strut in a spaced relationship thereto.

A caster for equipment, furniture and medical equipment, the caster including a support arm that includes a base portion and a top portion and receives an attachment bolt wherein the base portion supports a wheel axle that supports at least one wheel; a direction fixing device; and a movable blocking element configured to lock the direction fixing device, wherein the moveable blocking element is in direct or indirect friction contact with the wheel so that a friction force that is caused by the friction contact causes a locking of the direction fixing device and a direction fixing of the caster in a first direction when the caster moves in the first direction.

A swivel trailer is described that can include a swivel hitch and swivel axle configuration which prevents a vehicle and trailer from jackknifing.

Embodiments of the present disclosure relate to a wheel assembly (104) for an article of luggage, such as a suitcase (100). The wheel assembly (104) comprises: a central support element (200); a first wheel (132) rotatably attached to the central support element (200); a second wheel (134) rotatably attached to the central support element (200) on an opposing side to the first wheel (132), wherein the first wheel (132) and the second wheel (134) share a common axis of rotation X; and wherein each of the first wheel (132) and the second wheel (134) are substantially hemispherical in shape.

A subject support lift includes a mast portion, a base portion, and a lockable wheel assembly coupled to the base portion. The lockable wheel assembly includes an axle member, a lockable wheel coupled to the axle member, and a pivot member pivotally coupled to the lockable wheel and defining an axis extending in a vertical direction, where the lockable wheel is rotatable about the axis defined by the pivot member. A locking member is coupled to one of the pivot member or the lockable wheel, the locking member being repositionable between a locked position, in which the locking member engages the other of the pivot member or the lockable wheel, and an unlocked position, in which the locking member is spaced apart from the other of the pivot member or the lockable wheel.

To provide a stage-corresponding caster device being entirely compact, able to smoothly and stably work, and able to easily get over a stage end face, a holder main body 1 attached to an attached member B and having a pair of left and right side wall portions 10, a main wheel supporting member 2 in which the main wheel 7 is pivoted to a lower portion 2b and an upper portion 2a is pivoted to the holder main body 1, a sub wheel supporting member 3 in which the sub wheel 8 is pivoted to a front portion 3c and a rear portion 3d is pivoted to the main wheel supporting member 2 coaxially with the main wheel 7, and a slide roller 30 attached to the sub wheel supporting member 3 on a forward position to the main wheel 7, are provided; and the holder main body 1 has a guiding groove 13 inclined backward and downward in side view on the side wall portion 10 to guide the slide roller 30, the front portion 3c of the sub wheel supporting member 3 is oscillated downward by contact of the main wheel 7 with the stage end face Ja, the sub wheel 8 is pressed to the stage upper face Jb, and the main wheel 7 climbs over the stage end face Ja.

A pallet with wheels and braking system, that can be interlocked with other pallets. The pallet has wheels underneath that allow the pallet to move in all directions. The pallet's braking system slows and stops the wheels on the pallet. There is interlocking connection capabilities on all four sides of the pallet that interlocks and connects multiple pallets together, and synchronizes the interlocked pallet's braking systems. There is also forklift access on all four sides of the pallet that allows the forklift to push, pull or lift the pallet, and operate the pallet's braking and interlocking systems. The pallet further includes corner bumpers to protect pallet, load stabilizers that prevent pallet from moving during transit, shelf rack bars that are installed or extended for additional support of goods and shelving, and wheel insets that prevent wheels from moving when pallets are stacked.

A coupling mechanism is provided for coupling a supporting element to a frame, and includes a base member and a C-shaped retainer. The frame includes a frame body and a leg member that has a leg body extending downwardly from the frame body to terminate at an enlarged leg end. The base member defines therein a recess for the enlarged leg end therein. The supporting element is coupled to a lower major surface of the base wall. The C-shaped retainer extends to be disposed about the leg body, and is configured to be detachably coupled to a surrounding wall of the base member for retaining the enlarged leg end in the recess.

A rail wheel set for a car which can be moved on a rail of a rail system has a bearing housing with a radial suspension for connecting the rail wheel set to the car, and two running wheels which are rotatably mounted on the bearing housing. Each wheel has a respective rail rolling surface, the shape of which is adapted to the contour of a running surface of the rail, and a respective ground rolling surface. The wheels can roll independently of each other on the running surface of the rail or on the ground. The rail wheel set is secured to a chassis of a car for transporting objects on a rail system.

The invention provides a caster comprising a bracket, a first transmission device and two wheels. The two wheels are connected by a transmission screw and are fixed to the bracket. The first transmission device comprises an annular retaining portion and a plurality of first balls, the plurality of first balls are equiangularly arranged in a circumferential direction of the annular retaining portion, and opposite sides of the annular retaining portion are respectively embedded in the respective wheels. The caster of the invention can solve the problems in the prior art that it is difficult to control the gap between the two wheels, the resistance generated between the two wheels is large and noise is easily generated.
