Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A seat adapter removably mounts a child seat to a wagon having two opposing walls and an interposed connecting wall, and includes two latch components that mount to the wagon's opposing walls. In some embodiments, the seat adapter includes a cross-member extending between the latch components so that the cross-member provides structural integrity to the wagon if the connecting wall is displaced from its upright use position. In some embodiments, the seat adapter and the child seat can be mounted to the wagon for use with the connecting wall in its upright use position, and in some embodiments the seat adapter and the child seat can be mounted to the wagon for use whether the connecting wall is in its upright use position or its displaced position, with no mechanical interference between any part of the wagon and any part of the adapter or the child seat mounted to it.

A mobility apparatus having: a base having casters; a handle assembly pivotally attached to the base; a locking mechanism operable to place the handle assembly into a plurality of positions corresponding to an operating mode of the apparatus, and maintain the handle assembly in one of the plurality of positions; an actuating mechanism coupled to the locking mechanism to actuate the locking mechanism; and wherein the locking mechanism comprises: a hub fixedly secured to the base; a hub ring rotatably secured within the hub and comprising attachment means for the handle assembly; a gas spring mechanism coupled to the hub ring to provide a mechanical advantage to assist an operator in lifting a patient; a breaking mechanism for the casters, wherein the breaking mechanism is operable to lock and unlock the casters simultaneously.

A folding dolly system, a base unit of a folding dolly system, and methods of forming and using a folding dolly system are presented. A folding dolly system comprises a plurality of interconnectable base units connected to form a substantially planar holding surface, each base unit comprising a first edge with a number of knuckles configured to form a joint, a second edge with a number of knuckles configured to form a joint, and a surface forming a portion of the holding surface.

Foldable strollers with removable seats and related methods are disclosed herein. An example stroller disclosed herein a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a mount, a lock disposed in the mount; and a handle having an extended positon and a retracted position relative to the seat. The lock is to move from a first position to a second position when the mount is disposed in the receiver to removably couple the seat to the frame, and the lock to move from the second position to the first position to release the seat from the receiver when the handle moves from the retracted position to the extended position.

A multi-functional folding trolley comprises a trolley frame including a front wall, two side walls, and a rear wall, wherein the front wall and the rear wall are formed by frames composed of connection rods, and the two side walls are formed by scissor-shaped connection rod assemblies. The multi-functional folding trolley further comprises an angle-adjustable trolley pushing mechanism connected to a rear upper part of the frame of the rear wall and an axle mechanism located at a rear lower part of the frame of the rear wall and having two sides respectively provided with tires capable of being assembled and disassembled rapidly. The two-wheeled multi-functional folding trolley of the invention is suitable for various occasions.

The present disclosure concerns a coupling mechanism for detachably attaching two or more utility modules to one another, utility assembles, mobile carriers and other attachable modules and articles.

In some implementations, a utility cart includes (a) a cargo hold having a cargo bed; (b) an assembly having a wheel arm having a first catch, a handle arm having a second catch, and a wheel; the wheel arm and handle arm coupled together at an angle and adjacent a pivot point; the wheel rotatably coupled to a distal end of the wheel arm; (c) a locking mechanism and a spring member, the locking mechanism having a first locking pin and a second locking pin; and (d) a plurality of bearing wheels disposed below a bottom surface of the cargo bed.
