Publication number: 20190105221Abstract: A collapsible wheeled walker with two side frames and two height adjustable upper body supports. The apparatus includes a seat that is slidably attached to the two side frames and is movable between a front position to facilitate an ample walking space inside the frames and a rear position for a user to sit. The apparatus may include an X-folder that facilitates collapsing the walker to a small footprint for storage and transportation. It may also include a left forearm gutter and a right forearm gutter as part of the upper body supports that give the user an upright walking posture for health benefits.Type: ApplicationFiled: January 20, 2018Publication date: April 11, 2019Applicant: ProtoStar, Inc., a Delaware CorporationInventors: Yichuan Pan, Peter James Fellingham, Zelin Zhang, Craig Timothy Shugert, David Michael Petersen

Publication number: 20190105220Abstract: A collapsible Wheeled Walker with two side frames and two height adjustable upper body supports. The apparatus includes a plurality of wheel direction locks each coupled to a wheel and adapted to lock the wheel in fixed moving direction or to release the wheel to turn freely. The apparatus may include a seat that is slidably attached to the two side frames and is movable between a front position for walking inside the frames and a rear position sitting. The apparatus may be converted to a transport chair by locking front wheel and releasing the rear wheels, and sliding the movable seat to the rear position. It may include an X-folder that facilitates collapsing the Walker to a small footprint. It may also include two forearm gutters as part of the upper body supports that give the user an upright walking posture for health benefits.Type: ApplicationFiled: January 15, 2018Publication date: April 11, 2019Applicant: ProtoStar, Inc., a Delaware CorporationInventors: Yichuan Pan, Peter James Fellingham, Zelin Zhang, David Allen Purcell, David Michael Petersen, Scott Allen Rieger

Publication number: 20190105222Abstract: A rollator including a frame having first and second side frames extending along respective ones of a pair of planes. First and second upper body supports are coupled to and disposable at an adjustable height above the frame. A pair of forearm gutters are coupled to respective ones of the first and second upper body supports for engaging and supporting a respective forearm of the user during use. Each forearm gutter includes a peripheral edge, a forward midpoint on the peripheral edge, and a rearward midpoint on the peripheral edge. Each forearm gutter defines a longitudinal axis bisecting the respective forearm gutter and passing through the forward midpoint and the rearward midpoint. The forward midpoint and the rearward midpoint on each forearm gutter fall between the pair of planes.Type: ApplicationFiled: October 2, 2018Publication date: April 11, 2019Applicant: Protostar, Inc., a Delaware CorporationInventors: Peter James Fellingham, Yichuan Pan

Publication number: 20180360686Abstract: A collapsible upright wheeled walker with adjustable armrests that support sufficient user upper-body weight to facilitate a natural upright gait and provide unassisted mobility for a wide range of mobility-impaired individuals. The apparatus may be easily and quickly folded (and unfolded) and may include bilateral stabilizing wheel suspensions to facilitate navigation over uneven terrain. The apparatus includes a frame-stiffening folder assembly and may also include mechanical brakes, an adjustable upper armrest assembly with removable padded forearm supports and two pairs of handles, at least one of which is disposed sufficiently forward to place the user within the polygonal footprint defined by the front and rear wheels to provide support without leaning, stooping, or risking falls.Type: ApplicationFiled: August 28, 2018Publication date: December 20, 2018Applicant: Protostar, Inc., a Delaware CorporationInventors: Peter James Fellingham, Yichuan Pan, David A Purcell, Nebojsa Sataric
