41 Wheelchair attachments US13425091 2012-03-20 US09050230B2 2015-06-09 Avital Fast; Devdas Shetty; Moshe Raz; Giora Rothman
Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a belt support frame, at least two rollers mounted on the belt support frame and a belt mounted around the at least two rollers. The belt support frame is adapted for mounting on the frame of the wheelchair such that as the wheelchair descends from the upper surface to the lower surface, the belt engages an edge of the upper surface and rolls around the at least two rollers slowing a descent of the wheelchair from the upper surface to the lower surface.

43 Assistant apparatus for surmounting barrier US12371038 2009-02-13 US07837201B2 2010-11-23 Pi-Ying Cheng; Kian-Poh Wong
The present invention provides an assistant apparatus for surmounting a barrier, which comprises a carrier body, an assistant mechanism, and a sensing/driving apparatus. The assistant mechanism, disposed at a side of the carrier body, having an assistant block disposed at the end thereof, functions to place the assistant block on the ground between the carrier body and the barrier so that the carrier body is capable of surmounting the barrier through the assistance of the assistant block. The sensing/driving apparatus, coupled to the assistant mechanism, functions to drive the assistant mechanism to generate the adjusting movement according to whether the barrier is detected or not. By means of the design of the present invention, the assistant block is adopted to reduce the height surmounted by the carrier each time so that the carrier is capable of surmounting the barrier section by section.

Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a front caster wheel slider assembly on each side of the wheelchair, a follower wheel assembly and a track belt damping bar. The front caster wheel slider assembly includes a piston that will quickly push the front caster wheels down after they roll over the top edge of the curb. The follower wheel assembly acts a sensor that will release the piston in the assembly after the front caster wheels roll over the top edge of the curb. As the back wheels of the wheelchair roll over and down the curb, the track belt damping bar slows the descent of the wheelchair.

51 Adaptive mobility system US239951 1994-05-09 US5513716A 1996-05-07 Vijay Kumar; Parris Wellman; Venkat Krovi
A wheeled mobility system, such as a wheelchair, having articulated limbs for providing a tractive force between the mobility system and a surface. The articulated limbs provide tractive locomotive forces under abnormal operating conditions wherein wheeled locomotion is inhibited by an obstacle or the like. Controlled drive motors coupled to the articulated limbs and the wheels of the mobility system provide for redundant actuation of the limbs and wheels. The wheeled mobility system is inherently omni-directional, provides superior mobility in difficult terrain or soil conditions, such as sand, clay, gravel and rocks, and further provides for surmounting of obstacles, such as steps, ditches and rocks. The limbs also give the chair versatility and allow it to be re-configured to satisfy the comfort requirements of the user. The limbs can further be used as a manipulator in order to perform tasks such as reaching for objects or pushing open doors.

56 Moving apparatus based on bearing points created by end of lever arms with changable length US15564733 2016-04-04 US20180104982A1 2018-04-19 Tam Minh Do
The present invention relates to moving apparatus based on bearing points created by ends of lever arms with changeable length. The lever arm comprises two main components: body and end of lever arm. Lever arm body moves spirally or pendulously around the axis which is different from its axis, end of lever arm moves in and out along the lever arm body. The combination of movement of body and end of the lever arm creates bearing points of the apparatus on the terrain, thus creating capability to overcome barricades of the apparatus. Moreover, the combination of these two movements, when following appropriate principles, creates equilibrium for the frame of the apparatus on various terrains.

The present invention relates to a curb climbing system for a wheelchair having a pair of rear larger drive wheels, a pair of small caster wheels, and a static hand grip for a caregiver being located at a back region behind an occupant seat; the system comprises: (1) a rear rollover-climb lever mechanically linked to a pivot to permit the caregiver located at the back-end region of the wheelchair to apply a downwards forceful thrust sufficient to shift the lever from an upward-position to a downward-position; and (2) a mechanical torque engagement system to translate the downwards forceful thrust to a rollover rotation torque around a pivot point on a stair-like curb, to climb over the stair-like curb. During climb procedure, a ratchet system provides unidirectional backwards rotation of the rear wheel pair and prevents forward rotation to block the wheelchair from rolling down the stairs for safety.
