A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and at least one tiller, configured such that forward and backward movement of said tiller will translate into movement of both steering wheels, wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.

A mobile carrier includes a first frame, a directional wheel pivoted to the first frame, a second frame pivoted to the first frame, a steering adjustment mechanism connected to the second frame, and a steering wheel. The steering adjustment mechanism includes a first rotating element and a second rotating element coupled to the first rotating element. When a first rotating axis of the first rotating element is perpendicular to a plane, the first and the second rotating elements are locked to each other and are capable of rotating around the first rotating axis simultaneously. When a second rotating axis of the second rotating element is perpendicular to the plane, rotational degree of freedom of the first rotating element is restricted, and the second rotating element is capable of rotating around the second rotating axis relative to the first rotating element. A steering adjustment mechanism is also provided.

A wheelchair frame assembly for a self-balancing board. The wheelchair frame assembly is mountable to the self-balancing board. The self-balancing board includes at least one gyroscopic assembly and includes two wheels on opposing ends of an axle, controlled by two upper surfaces that independently pivot about the axle. Independent pivoting of each of the two upper surfaces controls a speed of an adjacent wheel, and a direction of the self-balancing board. The wheelchair frame assembly includes a seat, a footrest, a forward caster wheel, a rearward caster wheel, a left handlebar, and a right handlebar. The handlebars interface with the two upper surfaces to enable an individual seated in the wheelchair frame assembly to control speed and direction of the self-balancing board by moving the handlebars, thereby pivoting the two upper surfaces and causing the two wheels to independently rotate.

A motorized accessory for a wheelchair includes a housing having a top end and a bottom end, a handlebar assembly secured to the top end of the housing, and a wheel assembly coupled to the lower end of the housing. The motorized accessory also includes an electric motor coupled to the wheel assembly that is configured to drive the wheel assembly. In addition, the motorized accessory includes a tow bar assembly having a proximal end coupled to the housing and extending outward to a free distal end, where the free distal end is configured to be removably coupled to the wheelchair. The motorized accessory is configured to latch to the manually driven wheelchair in order to convert the manually driven wheelchair into a motorized wheelchair.

A travel route creation system which creates a travel route for a personal mobility vehicle, the system including a controller configured to create the travel route in which an entering angle to a bump or a slope is set within an angle range of 45? and more based on map data indicating the bump or the slope which the personal mobility vehicle can travel over, when creating the travel route for the personal mobility vehicle to pass the bump or the slope.

The present invention relates to a wheelchair footrest 1, comprising a continuous foot support 10 or two separate foot supports 10 for supporting the feet of a user; and at least one lighting means 20; wherein said lighting means 20 is fixedly arranged on at least one of said foot supports 10 to illuminate at least a floor area 40 on a front side 102 of said wheelchair 100; and the lighting means 20 comprises an LED strip which is fixedly arranged on the underside 12 of the at least one foot support 10, and wherein the LED strip has a length BL which extends over at least 50% of the width B of the at least one foot support 10. The present invention relates also to a wheelchair 100 comprising a corresponding wheelchair footrest 1.

A mobile carrier includes a first frame, a directional wheel pivoted to the first frame, a second frame pivoted to the first frame, a steering adjustment mechanism connected to the second frame, and a steering wheel. The steering adjustment mechanism includes a first rotating element and a second rotating element coupled to the first rotating element. When a first rotating axis of the first rotating element is perpendicular to a plane, the first and the second rotating elements are locked to each other and are capable of rotating around the first rotating axis simultaneously. When a second rotating axis of the second rotating element is perpendicular to the plane, rotational degree of freedom of the first rotating element is restricted, and the second rotating element is capable of rotating around the second rotating axis relative to the first rotating element. A steering adjustment mechanism is also provided.

Wheelchair convenience systems including a removably attachable footrest that has a biased footrest platform and a lever for moving the footrest platform from a first position to a second position. The invention also includes a cane retainer that positions a cane between a first and a second handgrip of the wheelchair and allow the cane to be used as a handlebar to more easily maneuver the wheelchair.

A motor-driven chair has a central drive wheel located beneath the seat and linked so as to be aligned with the facing direction of the seat. A user turns the direction of motion by rotating the seat relative to a surrounding stabilizer assembly so as to turn the seat and the drive wheel towards a direction in which he wishes to move. A suspension arrangement maintains a desired distribution of user load between the drive wheel and the stabilizer assembly. A combination of fixed-axis wheels with castered wheels provides angular anchoring of the stabilizer assembly to facilitate the seat steering process. The entire structure is preferably foldable for easy transportation and storage.

Provided is a wheel (6a) in which a disk (62) includes a ring-shaped rim (60) on which a tire (6b) is fitted, and a disk (62) having a flat circular shape and disposed on an inner circumference of the rim (60). The disk (62) includes a first rib (62a) and a second rib (62b) which extend in a radial direction of the disk (62). A width of each of the first rib (62a) and the second rib (62b) in a circumferential direction of the disk (62) increases toward an outer circumferential side of the disk (62).
