An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

A mobilization device adapted to be attached to a piece of conveying equipment such as a gurney. The device includes a base. The coupling structure is connected with the base for supporting at least a portion of the conveying equipment. The device also includes a wheel assembly that is sized to hold the wheels of the conveying equipment off of the ground. The wheel assemblies of the device are used to move the conveying equipment and include tires having a relatively larger height and width to aid in increasing the mobility of the conveying equipment.

A mower may have a removable mower deck and a removable attachment which includes a hopper and conveyor assembly for discharging particulate material from the hopper.

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 creeper includes a frame including side rails at a first height; legs with a flat portion at a different height than the first height; each of the legs including a through hole; each of the through holes being capable of receiving a respective stem of a respective caster assembly within either end thereof; such that the frame can receive the stems in a first position of the frame, and the frame can receive the stems in a flipped position of the frame, thereby providing the raised position and the lowered position for the pads. A hinge assembly is hidden from normal view, where the hinge assembly is positioned entirely below a headrest pad and a body pad. A method includes adjusting the creeper between the raised position and the lowered position for the pads.

The present invention provides a structure for assembling a snap-on caster of a draw-bar case. The draw-bar case includes a case body and four caster assemblies. The caster assembly includes a caster and an upper positioning cover. The caster includes a mounting pedestal and a universal wheel. Four sides of the case body are each provided with an installation slot. Several insertion plates are disposed on an inner side surface of the upper positioning cover. The installation slot is penetrated to form a through hole that is disposed corresponding to the insertion plate. The installation pedestal is provided with a buckle plate that is disposed corresponding to the through hole. The buckle plate is penetrated to form an insertion hole. Both sides of one end of the insertion plate are each provided with an inverted buckle. The insertion plate is snap-fitted onto the insertion hole after passing through the through hole and the insertion hole sequentially.

A removable wheel assembly includes a mounting base, a caster assembly and a detachment mechanism. The mounting base is provided with an insertion hole and a transverse guide groove communicated with the insertion hole. The caster assembly includes an insertion shaft, a wheel bracket, a rotating wheel and a housing. The insertion shaft includes a first end portion, and the first end portion is provided with a first engagement portion. The wheel bracket is connected to the insertion shaft. The rotating wheel is mounted on the wheel bracket. The housing includes a first housing and a second housing engaged with each other, and both the first housing and the second housing cover an outer side of the rotating wheel. The detachment mechanism includes a sliding member slidably disposed within the transverse guide groove and an elastic member connected to the sliding member.

The invention describes a system for locking and releasing a wheel (1) to and from a wheel support (2). The system comprises an interlocking mechanism (3) comprising a guiding slot (4) on the wheel support (2), and a guided structure (5), positioned on a stationary wheel section (6) of the wheel (1), mating with the guiding slot (4). The system further comprise a U-shaped locking tool (7) comprising two lever arms (8a, b) joined by a gripping bridge (9) at one end, and having an arm pivot structure (10) interacting with a wheel pivot structure (11) positioned on the stationary wheel section (6). The locking tool further comprises a pushing arm (13) interacting with a support slot (16) in the wheel support (2) for pushing the guided structure (5) into the guiding slot (4) when mounting the wheel, and for pushing the guided structure (5) a first distance (D1) out of the guiding slot (4) when releasing the wheel.
