  • Patent number: 6026833
    Abstract: Pockets for use on a crutch consisting of a front panel and a back panel secured to one another along three sides, leaving an open end. Alternatively, the pocket has at least one side panel positioned between the front and back panels. The back panel preferably has a length greater than the length of the front panel and the width of the side panel to form a closure flap. The pocket securing portion is affixed to one end of the back panel proximate the open end and secured to the crutch at the horizontal top rail by eye hooks. A retaining strap proximate the closed end secures the pocket to the side rails. In another embodiment for use on the lower portion of the crutch, the back panel has a length at least twice the length of the front panel and is folded upon itself to form a U-shape. A channel is secured to the crook of the U-shape to form a channel to receive a retaining bolt secured to the side rails. A secondary layer is affixed to a second leg of said U-shape to form a second pocket.

  • Patent number: 5657783
    Abstract: Forearm rests are combined with a conventional invalid walker. The forearm rests are located generally spaced above the normal hand-grips. The forearm rests are advantageous for providing inward lateral support to the user's outwardly flexed forearms while the user is grasping the hand-grips and while the user is one of (i) maneuvering the walker and (ii) partly supporting and stabilizing him or herself while standing and walking. The forearm rests provide better stability and support for a user who has diminished arm strength and/or diminished motor control over his or her arm muscles. The forearm-rests can be formed in an accessory apparatus that allows attachment to a conventional walker (without forearm rests) in order to enhance the walker and give it the desirable forearm rests.

  • Patent number: 5645095
    Abstract: A waterproof, stain proof and nonporous crutch pad cover formed out of a material having a low coefficient of friction. The crutch pad cover includes an elongate slotted body member having first and second sides which are adapted to partially encircle the periphery of a crutch pad along a portion of its length, a first end portion having an inwardly directed flanged end section which is adapted to enclose a first end of the crutch pad and a second end portion which is adapted to cover a second, opposite end of the crutch pad. A flap securing system is utilized to secure the first and second sides of the body member about the crutch pad proximate the second end thereof. A plurality of outwardly projecting stop members positioned proximate the first and second end portions of the body member are provided to prevent the under arm area of a crutch user from slipping off the low friction crutch pad cover.

  • Patent number: 5495867
    Abstract: A dual handled cane having the handles spaced at a predetermined distance to provide excellent uprisal characteristics is disclosed. The cane is a unitary structure having an upper handle which is useful whenever a user is in a standing position. A lower handle is spaced a preselected distance from the upper handle and a preselected distance from the tip of the cane. An infirmed user can use the lower handle as a grip when the user is rising from a chair. The second handle is connected to the shaft of the cane, that is, the straight shaft portion of the cane by a gooseneck wherein both handles are geometrically centered over the load bearing shaft of the cane. A load bearing shaft generally comprises two elements; one, a telescoping lower element which includes the tip of the cane and an upper element into which the lower element slides so that the length of the shaft may be adjusted to fit more comfortably the height of a particular individual.

  • Patent number: 5224924
    Abstract: A back treatment device comprising a spaced pair of adjustable crutches (26L, 26R), for supporting the upper body of a user. Each crutch includes an air-inflatable underarm member (44) for comfort. A pair of forearm rests (140L, 140R) and a pair of padded handles (70L, 70R), all adjustable, are positioned such that a handle and rest are located laterally of a respective crutch. The three pairs are movably supported such that the user can be alternately supported on each pair or on combinations of pairs. A spring scale (90) is mounted between lower ends of the crutches such that the user sits on the scale while monitoring a conveniently located weight indicator. By slightly depressing his or her shoulders, the user uses the body support members (crutches, forearm rests, handles) to induce spinal traction. Feedback from the scale allows the user to accurately control the traction with minimum effort. Using the device takes pressure off of spinal discs while symmetrically strengthening supportive back muscles.
