A foot-operated rear-leg roller mechanism lets chairs move with less effort, then return automatically to a stable, non-rolling position.

A tiltable carrier body with detachable rollers lets a tumble dryer roll easily, corner smoothly, and stand securely with low assembly effort.

A smooth channel, cylindrical post, and saddle braces use static friction to hold height while removing threaded bacteria harborage.

Combining fluid flotation with a torus bearing, this wheel pad moves heavy loads over uneven surfaces and small obstructions with lower resistance and tipping risk.

Mobile robots move fabric inventory pods through dynamic storage layouts to improve space use, speed order response, and raise throughput.

Retractable wheels let a stacked mixer drawer roll out for tool access, then lock back into a stable under-cabinet position.

An uneven-height caster plus two adjustable feet speeds leveling of analytical lab equipment on non-planar floors while keeping wall placement practical.

A single caster yoke with standardized mounting features supports selective brake and trim components, cutting redesign, tooling, and inventory burden.

A raise-lower wheel mechanism lets an appliance drawer roll out for tool installation, then lock back in place for stable storage.

Permanent friction braking keeps rolling furniture stationary in use while still allowing controlled repositioning with applied force.

A pre-stressed carrier structure shifts from rolling to high-friction contact under load, enabling easy movement, shock absorbency, and slip prevention.

A multilayer wrap-around glide uses a melted bonding layer and durable felt to stay attached to tubular chair legs and protect floors.

Angled attachment spikes and an adhesive base secure heavy objects for sliding transport while protecting floors and reducing labor.

A hard ferrule and replaceable soft foot reduce glide wear, fit tubular legs securely, and adapt furniture movement across floor types.

A replaceable glide base with cushioning and swivel contact adapts to different floors, reducing wear and helping prevent surface damage.

A block spring and curved-slot axle path absorb shocks on uneven ground while maintaining wheel contact and reducing jolting and noise.

An annular backbone bearing race protects the mount portion and spreads load more evenly, improving hubless caster durability.

A sleeve-and-ring wheel fixation replaces threaded axle parts to cut wheel-set weight, simplify assembly, and lower production cost.

A matted cup-and-sidewall glide uses adhesive and elastic retention to fit varied leg sizes and prevent detachment that can damage flooring.

A low-friction thermoplastic coaster lets heavy kitchen equipment slide easily for cleaning while avoiding caster wear and trapped liquid.

A tab-and-groove caster shifts load from plastic yoke arms to the wheel, improving durability while removing separate axles and rivets.

Heat-shrink tubing secures floor protectors to furniture legs and casters, improving grip durability, installation ease, and appearance.

A yoke tab shifts load into a wheel groove, enabling lighter plastic casters to support weight while reducing yoke stress.

Elastic hub hooks and a two-plate cover structure keep a flanged roller cover securely attached under impact while simplifying assembly.
