  • Patent number: 7347497
    Abstract: A manipulation device is for wheelchair footrests that have a pair of shafts (8) extending forwards from opposite forward sides of the main frame (2) and a pair of foot plates (9) pivoted at lateral portions to the shafts. This device has manual levers (21) at the forward sides and actuating means (40) that connects the levers (21) to foot plates (9) and consists of a resilient tube (41), a metal wire (42) and a setting retainer (43) for securing the tube to the wire. The tube (41) can elongate in response to an extraordinary tension exceeding a normal stress imparted to said tube, and the wire (42) loosely inserted in the tube (41) can alter an exposed length. An end of each wire (42) is connected to the foot plate (9) at its rear portion located near the shaft (8) pivoting the foot plate. An end of each tube (41) is connected to the manual lever (21) operating to pull up the tube (41) with the wire (42) such that the foot plate (9) rotates and rises to the upright idle position.

  • Patent number: 7344055
    Abstract: A pivoting wheelchair backpack holder is provided. The pivoting wheelchair backpack includes a lever rod and a swing-out handle to move the lever rod, a frame moved by the lever rod, and a backpack attached to the frame. In its closed position, the backpack rests behind the user sitting in the wheelchair with the handle positioned flush to the side of the wheelchair. The user grabs the handle from its resting position, locks the handle into place against the lever rod, and pulls the handle to move the lever rod. The lever rod opens the frame, which then moves from the back of the wheelchair to the side of the wheelchair. A second hinged joint between the lever rod and frame allows the user to pull the backpack down toward the user. The user can access the backpack now at his or her side. The user can close the frame by pushing the frame back up, moving the handle in the opposite direction and replacing the handle to its resting position.

  • Patent number: 7306250
    Abstract: A method of attaching a manually operated wheelchair to a motorized scooter using an angle iron, an adjustable bar that has a left segment, a middle segment, a right segment and a pair of adapters. A user slides the middle segment over the left and right segments, and inserts screws into left and right holes in the middle segment and aligned holes in the left and right segments. The user then screws the adapters onto upper ends of the left and right segments and snaps them into position on the underside of the wheelchair. Next, the user removes the seating apparatus from the scooter, fastens the angle iron to the floor of the scooter by inserting a pair of bolts through the slots in the angle iron and tightening the bolts with a pair of matching nuts, and places the bar squarely against the angle iron.

  • Patent number: 7303203
    Abstract: Wheelchair hand rim device comprised of a heat conducting tubular hand rim and a continuous circumferential elastomeric interface that has a cross-sectional contour comprised of an outwardly extending horizontal member having a proximal end coupled to an outboard side of a wheel rim transitioning into a downwardly depending member terminating to a distal end coupled to an inboard upper portion of the tubular hand rim such that a majority of the tubular hand rim is exposed and devoid of the elastomeric interface. When braking, a user only uses the heat conducting tubular hand rim. When pushing, the user grips across both the tubular hand rim and the contoured elastomeric interface, which deforms to fit the hand, thereby providing improved comfort, frictional coupling, and impact attenuation.

  • Patent number: 7293620
    Abstract: A front wheel stabilizing device includes a mount adapted to be secured to a main frame of an electric motor-driven wheeled vehicle, and an axle disposed between two side plates of the mount. A wheel mounting member has a tubular head which is rotatably sleeved on the axle, and a cantilever arm which extends from the tubular head forwardly to terminate at a wheel-carrying end for mounting a stabilizing wheel thereon. The stabilizing wheel can yield under a jolting force that arises as a result of movement of the stabilizing wheel over an uneven ground so as to displace from a more tractive position to a less tractive position. A torsion spring has a coiled segment which is wound on the tubular head, and two urging ends which abut against the mount and the cantilever arm, respectively, so as to bias the stabilizing wheel downwardly, thereby restoring the stabilizing wheel from the less tractive position back to the more tractive position.

  • Patent number: 7252300
    Abstract: Manual braking system with a variable braking force for a wheelchair. Caliper type brakes positioned to mount on and exert braking force on disks mounted to interior “disk” hubs rotatably mounted to the wheelchair frame wheel hubs are mated with the “disk” hubs with a push button release pin allowing the wheel to be quickly removed without disturbing disk braking system. Caliper brakes are actuated by a manual lever arm, cable and pulley combination mounted to the frame of the wheelchair. The lever is provided with and without a plunger mechanism. A plunger mechanism allows the user to maintain the manual braking force exerted on lever without hands. The plunger mechanism is fixably mounted and positioned to insert a plunger head into notches on the lever. The force exerted by the plunger head is sufficient to hold the plunger head within the notch and prevent movement of the lever without manual force.

  • Patent number: 7052023
    Abstract: A wheel chair includes wheel frames which can be adjusted up and down, moving devices and brake devices are connected to two respective sides of the two wheel frames. Support devices are connected to the wheel frames so as to adjust the depth of the wheel frames to which arm rest devices are connected. A folding device is connected between the wheel frames and an assistant device is connected to the folding device. A positioning device is connected to the assistant device so that the wheel chair can be adjusted in many ways to meet different needs of users. The modularized devices effectively reduce manufacturing cost of the wheel chair.
