An apparatus includes first and second side portions, and a horizontal portion disposed between the first and second side portions. Each side portion includes an inner wall joined to the horizontal surface, an exterior wall, and a top portion connected that define a volume within the side portion. Each side portion also includes first and second wheels within the volume, the first and second wheels having a raised wheel position and a lowered wheel position. Each side portion also has an arm coupled to the outer wall of the side portion, the arm having a first arm position and a second arm position. Movement of the arm from the first arm position to the second arm position causes the wheels to move from the raised wheel position to the lowered wheel position.

A debris shield for engagement to a caster wheel is provided. The debris shield surrounds an opening in which a well of a caster wheel assembly is positioned. A flexible shield extending from the perimeter edge of the body and having a complimentary shape thereto, sweeps debris out of the path of the wheel rolling on a surface. Front and rear ends of the body are preferably pointed to provide angled portions of the debris shield of the flexible shield. Bristles of the shield may be reinforced by flexible adhesive and or mesh. An optional guard which is engageable to cover the shield around the projection points may be added.

A system for compensating for a flat tire, including a tire deployment sub-system and a tire pressure monitoring sub-system. The tire deployment system comprises an extendable auxiliary tire mounted to the frame of the automobile that is in communication with the tire pressure monitoring system and a user interface. The tire pressure monitoring system is adapted to monitor the internal pressure of the tires of the vehicle, via either direct or indirect means, and send a notification signal to the tire deployment system when the pressure sensor detects that one of the tires of the vehicle is losing pressure. The deployed auxiliary tire provides a temporary support for the tire that has gone flat, allowing the driver to continue driving for a period of time and thereby obviating the need to immediately pull to the side of the road and change out the flat for a spare tire.

A universal rotating module is provided. The universal rotating module comprises a main body including a first portion and two second portions; a main shaft passing through the through groove to pivotally connected to the main body; two bearings sleeved on and pivotally connected to the second portions along the second direction, respectively; two rollers pivotally connected to the second portions along a third direction, respectively; two hemispherical casings fixed to the two bearings, respectively. The first portion includes a through groove extending along a first direction, and the two second portions protrude from opposite sides of the first portion along a second direction, respectively. Each of the hemispherical casing includes a through hole at the top, and a portion of each of the rollers is exposed out of the corresponding through hole.

A pallet moving system includes a pallet dolly puller, and a pallet dolly with a guiding structure thereon permitting and facilitating the blind engagement and disengagement of the dolly puller to the pallet. The dolly puller includes caster wheels, a handle, and at least one projecting portion configured to mateably couple with recessed portions on the underside of the pallet dolly in order that the pallet dolly may be moved and readily re-positioned even in confined spaces.

A roller assembly comprises a housing having an outer surface attached thereto, and a braking arrangement positioned at least partially within the housing. The braking arrangement is configured to increase resistance to rotation of the housing proportionally to a load applied against the outer surface.

The present application includes a system and method for transporting a car seat outside of a vehicle. The system includes a wheel assembly configured to couple to a portion of the car seat. The wheel assembly attaches to existing base attachment portions on the car seat to minimize any need for retrofit operations. The system further includes a mobility handle configured to adjust in length and couple to a portion of the car seat. The mobility handle is designed to allow an individual to guide and control the movement of the car seat on the wheel assembly.

A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.

A wheel float that articulates in multiple directions for efficiently and safely moving an object across a surface having a non-planar obstruction. The wheel float has a pair of walking beam assemblies, a crosstube assembly having a crosstube interconnecting the walking beam assemblies, a pedestal supported by the crosstube and a center pivot assembly that allows the crosstube assembly to pivot relative to the pedestal. The pedestal has a support surface that supports the object above the walking beam assemblies. Each walking beam assembly has a base plate, wheeled casters, a pair of spaced apart hangers and a bushing assembly associated with an articulation opening in each of the hangers. Pivot members at the ends of the crosstube assembly engage the hanger bushings to allow the respective walking beam assembly to pivot relative to the crosstube. Thrust blocks or locating plates position the walking beam assemblies on the crosstube assembly.

An integrated anti-tip mechanism is provided for aiding prevention of an electronics rack from tipping. The anti-tip mechanism comprises a long portion with a first end and a second end, the first end coupled to a base of the electronics rack and the second end coupled to a first end of a short portion. The first end of the short portion is coupled to the second end of the long portion and a second end of the short portion further coupled to a caster. When deployed, the caster rolls in a same direction as a set of casters beneath the electronics rack. The caster is a predetermined distance off the floor such that the weight of the electronics rack is carried by the set of casters beneath the electronics rack but contact the floor if the electronics rack tips thereby preventing the electronics rack from tipping past a predetermined angle.
