A warming device for the handrim of a wheelchair is disclosed herein to relieve discomfort caused by manually wheeling a wheelchair in cold and/or wet weather conditions. The warming device includes a hand interface, a mount, and a heating element. The warming device is configured to mount the tube of a handrim. The heating element of the warming device is coupled to an electronics system including a printed circuit board and a battery. The electronics system may be internal to the warming device, or may be housed in an external electronics box mounted similarly to the handrim or the rear wheel of the wheelchair.

Systems and methods for navigating a residence include a first household appliance, a second household appliance, a beacon, and a portable user interface device. The systems and methods include determining a plurality of paths through the residence. The systems and methods also include receiving, from a user interface of the portable user interface device, an input comprising a selected destination and determining a current location of the portable user interface device based on a short-range radio signal after receiving the input. The systems and methods further include selecting one path from the plurality of paths through the residence. The one selected path starts at or near the determined current location of the portable user interface device and terminates at the selected destination. The systems and methods also include providing guidance to and along the one selected path.

A suspension for a vehicle is provided. The suspension includes, for example, a frame, at least one drive assembly and at least one caster pivot arm. The at least one drive assembly and the at least one caster pivot arm are pivotally connected to the frame at a common pivot axis such that the drive assembly and the front caster pivot arm are pivotable relative to one another.

A posturally supportive toilet seat apparatus 1 comprising a seat 10 having a base portion 11. The base portion has leg support features 12 and an aperture 13 formed therein for passage of waste therethrough. The apparatus 10 further comprises a back support 14 which extends from a rear end of the base portion 11. The back support 14 and leg support features 12 are shaped, dimensioned, and, in an in use-configuration, adjustable/positionable relative to each other in an oblique relationship. In the in-use configuration, the thighs and torso of a user seated on the seat 10 are encouraged to form an acute interior angle therebetween, with knees locatable above hips, essentially resulting in the user adopting a squat position.

Devices described in this disclosure can interconnect a wheelchair with another wheeled apparatus. For example, this document describes interfacing devices that releasably receive the front wheels of a wheelchair and the rear wheels of another wheeled apparatus in such a way that a user of the wheelchair can conveniently maneuver the wheeled apparatus in conjunction with the operation of the wheelchair.

A lifting mechanism has a base to which a pivot of a parallelogram structure. A spring extends from a first link of the parallelogram to an adjustable termination point on a second link of the parallelogram to form a lifting triangle. The spring termination point is displaced from a main pivot of the parallelogram to create an adjustable “lever arm” to vary the lifting force. A lifting power adjustment mechanism adjusts the position of the spring termination point. An extension is in fixed relation to one of the parallelogram links and maintains its angle with respect to the horizontal when angles of the parallelogram are varied upon raising or lowering the lifting mechanism between a sitting mode and a standing mode. The extension serves as a base for a rear seat section. A front seat section is pivotally attached to the rear seat section allowing it to swing downward upon elevation of the lifting mechanism.

Disclosed is a multifunctional exercise chair for body stretching, comprising a wheelchair frame body, wherein a mounting frame is detachably mounted on an end of the wheelchair frame body away from the driving rear wheel and located under the seat cushion, a pedal gear is rotatably mounted at a bottom of the mounting frame and a pedal is provided thereon, a hand crank gear is rotatably mounted on a top of the mounting frame and a hand crank handle is provided thereon, a rotating shaft is provided between two driving rear wheels; a driven gear is fixedly mounted on the rotating shaft, a supporting chain gear is mounted on the mounting frame and arranged adjacent to the pedal gear, and the hand crank gear, the pedal gear, the driven gear and the supporting chain gear are wound and connected by a transmission chain.
