  • Patent number: 8858401
    Abstract: A training apparatus for a Nordic walker has an elongated pole whose lower end carries at least one wheel having a freewheel permitting rolling of the wheel on the surface only in a forward travel direction. A forearm rest is freely pivotal on an upper end of the pole and defines with the pole an angle increasing on forward rolling of the wheel from a position behind the athlete to a position in front of the athlete as the arm in the rest swings forward in the travel direction. A handgrip fixed on a front end of the forearm rest is gripped by a hand of the forearm in the rest and pivots with the forearm rest. A spring braced between the rest and the pole and pivotally biases the rest so as to increase the inclination angle.

The apparatus provides for one crutch that comes up from the side support of the walker and thus the side of the user's body and is adjustable in height, as is the walker support handles, such that the invention can be customized for any sized user. The adjustment is facilitated by use of spring pin slip fittings, and thus can be adjusted in a matter of minutes without tools. The crutch support can be easily moved from the right to left hand side of the walker by use of a removable clamp system. It is also envisioned that certain models of the invention can provide crutches on both the right and left hand side of the walker simultaneously, based upon the needs of the patient. When not in use or not needed, the invention folds up in a manner similar to a conventional walker thus providing a low profile for ease of storage.

  • Patent number: 7040637
    Abstract: A rollator with a tubular frame assembly includes a pair of U-shaped side frames connected by a front brace. Each side frame has a cross bar that extends between front legs and back legs of the frame. The side frames are pivotably attached to the front brace so that the side frames can fold inwardly. The rollator has a molded rigid seat that is mounted on pivot brackets to allow it to pivot upwardly out of the way of the user. The pivot brackets have an offset axis of rotation so that the seat is arranged in a curved area of the front brace when pivoted upwardly.

  • Patent number: 6899660
    Abstract: A walker particularly suitable for rehabilitation of a patient's legs includes a base provided with casters, a pair of handlebars, and a suspension frame for holding a safety belt. A leg separator is height-adjustably connected to the base to locate between and separate apart the patient's two legs, so that a cerebral palsied patient may bear inner sides of two legs against two lateral sides of the leg separator during practicing walking. Direction control members adapted to limit the casters to rotate forward and backward only are provided on the base to effectively enable the cerebral palsied patient to practice walking straightly forward.

  • Patent number: 6877520
    Abstract: A cane having a base formed from a cup-shaped support having a concave bottom surface and a top surface defined by a circumscribing exterior sidewall having a bottom edge. The concave bottom surface is formed to have a plurality of resilient projections extending therefrom a distance to project slightly beyond the bottom edge of the sidewall. The projections are formed in a spoke-like pattern on the bottom surface such that the density of the projections is greater near the central section of the bottom surface than at the periphery of the bottom surface. The projections are also formed to have a length that varies according to their position on the bottom surface so that a substantially planar contacting edge is presented to a support surface.

  • Patent number: 6675820
    Abstract: The safety support device of this invention includes a frame having a mounting section. A pair of forward legs are attached to a forward end of the mounting section and a pair of rear legs are attached to a rear end of the mounting section. Each leg has a distal end to which is attached a roller assembly that includes a roller member mounted so that with the weight of the user bearing down on the assembly the roller member is prevented from moving. In a second embodiment used to assist injured or elderly person stand erect, the legs are long and arm support members engage the arm pits of the user when the user is being supported by the device.

  • Publication number: 20030127121
    Abstract: A walker for providing a patient having a breathing disorder the ability to carry an oxygen bottle safely upon the walker. The walker has a pair of side frames having front vertical bars that are connected by a pair of cross members. Wheels are attached to the front bars of the frame for propelling the walker. An open top canvas bag containing the oxygen bottle is suspended from the top cross member so that the center of gravity of the bottle lies in a common vertical plane with the wheel axis and is centered between the frames. Stabilizers are provided to prevent the bottle from moving side to side or out of the frame.

  • Patent number: 6494469
    Abstract: A rolling walker 1 comprises a first frame 3 supported by a front caster 2 at both ends thereof and a second frame 5 supported by a rear caster 4 at both ends thereof, and a handle 7 provided to either first frame 3 or second frame 5. The first frame 3 and the second frame 5 are foldably connected each other by a connecting shaft 6. The rolling walker 1 has a closed frame fixing means 11 which fixes the first frame 3 and the second frame 5 in a closed position and connects the first frame 3 and the second frame 5 to stand when the first frame 3 and the second frame 5 are rotationally folded around the connecting shaft 6, so that each frame 3, 5 can be kept folded to stand when the rolling walker 1 is not used.

    Abstract: A sunshade base comprises a base adapted to engage with a support tube of a sunshade and two wheel assemblies each having a mounting plate and at least one wheel. The mounting plate is pivotally mounted to the base. The wheel is rotatably mounted to the mounting plate. The mounting plate is pivotable between a storage position in which the wheel does not contact the ground and an operative position in which the wheel is located on the ground and thus raises the base above the ground.

  • Patent number: 6318392
    Abstract: A supportive walker includes a front frame, a rear frame with a connection bar connected thereto and a pair of retaining frames connected to the front frame so that the connection bar extends through the two passages of the two retaining frames. A safety device has an engaging portion and an urging device which is biased between the retaining frame and the engaging portion. The engaging portion is releasably engaged with the connection bar by operating the urging device. Therefore, the front frame and the rear frame are expanded or folded securely when the urging device is released. The connection bar of the rear frame is movable in the passages of the retaining frames when the urging device is pressed.
