A connective unit to connect a roller with a seat's leg is disclosed. The connective unit comprises a supportive arm, a plastic cylindrical member, a pivotally connective member and a roller. The plastic cylindrical member may engage with a cylindrical hole provided in the supportive arm. The upper end of the pivotally connective member may engage with a first connective hole and the lower end of the pivotally connective member may engage with a second connective hole of the roller. Thanks to presence of the plastic cylindrical member, when the pivotally connective member rotates and causes the roller to rotate with it, the supportive arm doesn't have any contact with the pivotally connective member and thus noisy friction and impacts between them as in the prior art may be avoided. Therefore, the plastic cylindrical member is difficult to wear out as the pivotally connective member rotates.

An exemplary embodiment of a caster adapter includes a connecting base for coupling the caster adapter to a caster, at least two panels forming at least part of an adapter member and defining the interior of the adapter member wherein at least a portion of a leg of an object is insertable into the interior of the adapter member. The adapter member may contain a leg conforming portion that protrudes outward from the interior of the adapter member and corresponds with a leg protrusion on a leg of an object wherein the leg protrusion will fit within the leg conforming portion such that the object may be lifted off the ground without the caster adapter, and coupled caster, slipping off of the leg. The leg may be inserted into the caster adapter through an opening in the side of the adapter member, wherein the opening is blocked by the use of at least one containment member interacting with the adapter member. The leg conforming portion may be customized depending on the leg protrusion location and size on the subject leg. The containment member not only acts to retain the leg within the caster adapter but also allows for quick release of the caster adapter from the leg. The adapter member of the caster adapter is customizable to fit various geometries of legs. The containment member may be retained in proximity to the caster adapter through the use of an attachment member that is attachable to the adapter member and the containment member.

A roller kit for a power washer surface cleaner attachment. A roller mount includes a bracket mounting a roller for rotation with respect to the roller mount and a clip for securing the roller kit to the surface cleaner attachment such that the roller is operatively aligned with the surface cleaner attachment for rolling over a surface to guide movement of the surface cleaner attachment along said surface. The clip includes a base portion supporting the bracket and an arm portion opposing the base portion. The clip is configured to bend resiliently in an opening direction to define an opening between the arm portion and the base portion for receiving a side wall of the shroud and to rebound in a gripping direction to grip the side wall between the arm portion and the base portion and thereby secure the roller kit to the surface cleaner attachment.

A wheel connecting device includes a mounting seat, a shaft, a sleeve member and a retaining member. The mounting seat defines an accommodating space and includes a surrounding wall that has an inner surrounding surface surrounding the accommodating space. The shaft has a first mounting segment that is inserted into the accommodating space, and a second mounting segment that is disposed under and connected to the first mounting segment. The sleeve member is sleeved on the connecting portion of the first mounting segment of the shaft. The retaining member extends helically around a neck portion of the first mounting segment of the shaft, and is in contact with the neck portion and the surrounding wall.

The invention relates to a caster for movable objects, and more particularly a bed caster, and at least comprises: a running wheel; a fork receiving said running wheel; a guide tube which is designed to be swivelable relative to the fork via at least one bearing; locking means provided on the fork side; and a braking system which can be brought into operative connection with the running wheel and is designed to block rotation of the wheels, characterised in that the braking system includes a brake shoe, a brake spindle, a guide pin and a cup-shaped guide element, wherein the brake spindle has groove-shaped guides, the cup-shaped guide element is provided with projections, and the projections can be brought into operative connection with the guides of the brake spindle in order to form the anti-rotation means.

A caster wheel bracket, a caster and a movable container are disclosed. The movable container includes a frame and a caster. The caster includes a caster wheel bracket and a caster wheel. The caster wheel bracket includes a support plate. A first restricting portion is disposed on an upper surface of the support plate. The first restricting portion is detachably fitted to corresponding two of the transverse rods. A second restricting portion is disposed on one end of the support plate. The second restricting portion is detachably fitted to a corresponding one of the longitudinal rods. A mounting portion is connected to a lower surface of the support plate for mounting a caster wheel. The caster can be mounted and dismounted quickly and the position of the caster can be adjusted according to the actual needs.

A caster mounting portion has a mounting member housing portion which houses the mounting member, the mounting member has a rotary shaft portion which is pivotally supported in a bearing recessed portion in the mounting member housing portion, an abutment body in which the rotary shaft portion is provided at an eccentric position and which is displaced by rotation to be widened to close the inside of the mounting member housing portion, an upper locking piece which engages with a locking receiving portion of an opposed wall, a lower locking piece which abuts against the bottom face of the aforementioned latching portion, and a locking stepped portion which is urged by a leading end of an elastic arm, climbing over the aforementioned latching portion, and engages with the lathing portion.

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.

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.
