  • Patent number: 9974367
    Abstract: A base for a walking stick, which is configured to dispose in a bottom end of a stick body of the walking stick to provide a buffering and shock-absorbing effect, may include a main body, a shaft, a first sleeve, and a second sleeve. An upper portion and a lower portion of the shaft respectively have a first connecting portion and a second connecting portion. Also, a buffering unit disposed on the first connecting portion can allow the second sleeve to be compressed and stretched. Thus, the walking stick can achieve the stretch motion stably, and buffer the reactive force from the floor. Thus, the base structure for a walking stick can allow the stick body to swing in all direction. Also, it can be used to stand on different tilted grounds, and improve the reliability and safety of the walking stick.

    Abstract: A walking supporter having a plurality of bottom frames with at least one curved element; a plurality of support frames connected to the curved element of the bottom frames; and at least one connecting element interconnecting the support frames. A user can stand up easily from a sitting position without exerting a force vertical to the ground because the walking supporter can be swung utilizing the bottom frame with a curved element. Furthermore, it is less likely that the walking supporter will get stuck even if there is a protrusion or a crevice on the ground because the bottom frame is formed of curved elements. The walking supporter is also appropriate for patients or the elderly who may not have enough arm-strength because it is possible to walk by pushing the walking supporter on the ground with a part of the bottom frame being in contact with the ground.

  • Patent number: 7624746
    Abstract: An adjustable cane includes a grasping mechanism, an actuator, an adjustable length inelastic linkage, a magnetic pickup, hanging tip and self-standing base. Pivotally mounted to the distal end of the cane, the grasping mechanism includes a pair of fingers defining a narrow valley for grasping small objects and a wide valley for grasping large objects. The adjustable length inelastic linkage transmits force from the actuator to the grasping mechanism. The magnetic pickup is mounted to the grasping mechanism to facilitate retrieval of ferrous objects. The hanging tip supports the cane from horizontal surfaces. The self-standing base allows the cane to stand upright on any flat surface.

  • Patent number: 7610926
    Abstract: A mobility device to provide ambulatory support includes a tubular body having upper and lower parts. The upper part has at least four, and preferably five, bends and includes a manually graspable handle portion between two of the bends, and a hook-shaped bend for engaging the user's forearm on three sides adjacent the elbow. An intermediate portion including another bend is positioned between two other bends, and is positioned between the handle portion and the bend located adjacent the user's elbow. The lower part includes a floor-engaging free end and defines an axis, preferably a generally vertical axis. The bends and other features of the upper part cooperate to provide improved support for a user's forearm. Also disclosed is a rocker-type end member either fixedly or slidably fitted to the lower part.

  • Publication number: 20090242008
    Abstract: An ambulatory support and traction device used as a flexible foot (1) added to a walking aid, such as a cane or crutch (6), is provided. The flexible foot (1) includes a bendable coil or spring (3) that allows angulation of a walking aid shaft (4) relative to the foot (1) without the loss of adherence of the foot to a ground surface (19). The allowance of angulation of the walking aid shaft (4) improves ambulatory support and balance when leaning on the walking aid or when traversing an inclined surface and can assist the user in rising from a sitting position to a standing position without repositioning of the foot. The flexible foot (1) has a rigid base (2) for structural support and a traction sole (17) to adhere to surfaces both indoors and outdoors and on different surfaces and environments.

  • Patent number: 7588044
    Abstract: The invention is for a foot assembly for a walking aid. The foot assembly is attached to a strut at a lower end of the walking aid. The foot assembly has a cylinder attached to a bottom of the strut and a foot pivotally attached to the cylinder by a foot bolt. The foot has a hemispherical portion and a flat ring portion. The foot bolt is positioned through a dome hole and a cylinder bottom opening, and the foot bolt is secured by a foot bolt nut that tightens on the foot bolt threads to attach the foot dome hemispherical portion to a concave cylinder bottom wall. A resilient foot pad is attached to a bottom of the foot. A spacer fits on the foot bolt and retains the foot bolt head inside the hemispherical portion.

  • Patent number: 7581556
    Abstract: A crutch-like mobility assist device includes a vertical support assembly, an underarm support mechanism, and a rotatable footer assembly, the rotatable footer assembly including an elongated ground-engaging foot pad, attachment members connected to the foot pad and having vertical posts, and an elongated connection member with openings through which the vertical posts extend. The connection member includes respective pairs of support blocks on opposite sides of the vertical posts with bores therethrough for shafts that also extend through the posts to enable the posts (and thus the foot pad) to laterally rotate around the shafts. The foot pads can come into parallel contact with the ground even when the vertical support to which it is connected is laterally oriented by the user. Torsion springs connected to the posts will return the posts to a central orientation relative to the connection member when the foot pad is lifted off the ground by the user.

  • Patent number: 7490617
    Abstract: A step-extending device is adapted for use in association with a walker to ascend or descend a stairway. The step-extending device may employ a first base and a second base, each of which is adapted to receive legs of a walker upon respective upper surfaces. The device may be used in connection with a frame that connects the first and second bases to each other. A cross member connects first and second bases. A frame includes one or more upright members with handles adapted for grasping and moving the step-extending device from one stair to another stair during use. The height of each of the first and second support bases is adjusted to approximate the height of stairs upon a stairway, so that stairs of essentially any height may be accommodated.
