The present disclosure relates generally to devices and methods which use the mechanical advantage of a lever and fulcrum along with the use of force from a user's body, foot, and leg muscles, to more ergonomically and safely install wheel assemblies on vehicles while keeping the user's back at a more ergonomic angle and allowing for both of the installer's hands to remain free for stabilizing the wheel assembly during installation. The lifting device provides a foot pedal, a lifting pad and a pivot point to position a wheel assembly on a hub and/or wheel studs.

A removable caster system includes a roller, a roller frame and a roller seat, the roller being positioned on the frame via a horizontal axis, the frame being inserted into the vertical shaft hole of the seat through the vertical shaft to form a detachable position; wherein a chute is installed on the upper surface with a trapezoidal stopper; a wire retainer is placed in the chute and is controlled by the movement of its narrowing section or the vertical axis to achieve removable function.

A wheel mounting structure relates to a structure for fixing the wheel to the wheel hub which includes a substantially cylindrical spigot joint part protruding from the hub axle part toward the vehicle body outer side with respect to the flange part. In the spigot joint part, the first cylindrical outer peripheral surface and the groove are formed. The annular protruding part is provided so as to protrude toward the center of the wheel from the inner peripheral surface of the center hole. In a state where the wheel is fixed to the flange part using the fastening members, the fitting part and the annular protruding part fit with each other. In a state where the fastening members are removed, the annular cylindrical protruding part is engaged with the groove.

The invention provides a wheel having a disk-shaped substrate having a first surface, a second surface and a periphery; and a radially extending channel formed within the substrate, wherein the channel has a closed end adapted to encircle an axle and an open end which terminates at the periphery such that the channel extends from the first surface to the second surface. Also provided is a method for installing and uninstalling wheels having the steps of supplying a wheel having a reversibly deformable radially and transversely extending channel having a first width, whereby the channel is adapted to frictionally and slidably receive an axle, urging the axle into the channel and toward the center of the wheel, whereby the channel reversibly expands to a second width to accommodate the axle; and allowing the axle to reside at the center of the wheel while the channel reverts to the first width.

A wheeled cabinet includes a container including compartments, a rear handle, drawers, and a storage between the drawers and a base; a pneumatic assembly including an inlet, connectors, a pneumatic cylinder on the base, a piston rod configured to move alternately upward and downward relative to the cylinder, and a controller for activating the cylinder; a lifting assembly including two opposite rails upwardly disposed on two sides of the base respectively, and an inverted U-shaped frame member slidably disposed on the rails and having an underside of a top secured to the piston rod; and a tire support assembly including a support secured to the frame member, two slides on two sides of the support respectively, a sliding tray secured to the slides, a slot on an inner surface of the tray, a moveable tab in the slot, and two rollers on two sides of the tray respectively.

A wheel construction (10) including a rim (12), the rim having an inner flange (16) and an outer flange (18), each of the inner flange (16) and the outer flange (18) having a first end (16a, 18a) and a second end (16b, 18b), the first end (16a, 18a) of each of the inner and outer flange (16, 18) being positioned axially outwardly relative to the second end (16b, 18b) of the respective flange (16, 18), the rim (12) further including a central well (20) positioned between the inner flange (16) and the outer flange (18), a pair of bead seats (22, 24), one being positioned adjacent each flange (16, 18), each bead seat (22, 24) having an axially outer end (22a, 24a) which is connected to a second end (16b, 18b) of the respective flange (16, 18) by a flange connecting portion (26, 28), and an axially inner end (22b, 24b) which is connected to one of a pair of side parts (30, 32), each side part (30, 32) being positioned between the central well (20) and one of the inner flange (16) and outer flange (18), and connected to the central well (20) by a well connecting portion (34, 36), the axially outer end (22a, 24a) of each bead seat (22, 24) being positioned radially outwardly relative to the axially inner end (22b, 24b) of the respective bead seat (22, 24), wherein at least one of the inner flange (16) and the outer flange (18) includes an extended portion (17, 19) which extends radially inwardly, such that a free end (17a, 19a) of the extended portion (17, 19) is positioned radially inwardly relative to the first end (16a, 18a) of the respective flange (16, 18), and wherein at least one of the side parts (30, 32) includes a substantially straight portion (38, 40) and a curved portion (42, 44), a first end (38a, 40a) of the straight portion (38, 40) being positioned adjacent the respective bead seat (22, 24), and connected to the respective bead seat (22, 24) by a curved connecting portion (46, 48), and a second end (38b, 40b) of the straight portion (38, 40) being connected to the curved portion (42, 44) of the side part (30, 3
