Abstract: The invention relates to wheelchairs, walkers, scooters, etc. used by disabled or recuperating persons in cases of injury or disablement of the lower leg, ankle or foot. In particular the invention relates to an asymmetrical side support four wheel side support kneeling walker to be used when a person's lower leg, ankle or foot is non-functional. Balance is provided by a side extension, similar to a training wheel, which extends outward from the same side of the walker as the immobilized leg. This side extension serves as an outrigger to give the wheels of the walker an asymmetrical arrangement relative to the center axis of the vehicle. The foot and leg support rectangular platform and tubular frame are adjustable. It is preferred that the device be easily folded for storage and constructed of steel tubing for durability and strength and have a hand brake for stability and safety.

Abstract: A controller for wheeled vehicles includes a mechanism which selectively shifts the vehicle between a mobile and a stable state. The vehicle may be a walker for easing an operator's efforts in walking and includes a selectively actuable stabilizer which fixes the position of the walker or releases it for rolling motion, thus providing a stable state or a mobile state, respectively. An actuator such as a button, pressure sensor, or lever, electrically and/or mechanically actuates a stabilizer brake mechanism to engage or release the brake and thereby allow the walker's mobility to be controlled when the actuator operates the brake to stabilize or to slow the motion of the walker. Preferably, lift applied to the vehicle itself releases the brake and allows mobility. The actuator may control an electrically actuated braking mechanism, in response to a sensor such as a strain gauge that may be adjusted to the needs of the patient; alternatively, lifters may be provided to act in response to the lifting force.

Abstract: Apparatus for aiding persons in rising or descending between seated and standing positions provides stability to a conventional walker. In a preferred embodiment, an apparatus has a platform portion and two flexible connection members. The platform portion is substantially rigid and includes two parallel rails. At forward end portions of the rails, openings are formed for pivotable attachment therethrough of the connection members. The connection members are also pivotably attached to a forward portion of the walker, so that when a person places his or her weight on the platform portion, the connection members transmit the weight to the walker, thereby stabilizing the walker.

Abstract: A patient support device, particularly a cane, includes a fifth leg that extends outwardly from a central portion of a base assembly at a region intermediate the first, second, third, and fourth legs. The fifth leg provides increased balance and stability for the user. Moreover, the base assembly includes a one-piece member constructed from a molded plastic composite material to reduce manufacturing costs. Additionally, the fifth leg is slightly recessed relative to the remaining four legs so that the patient's weight is evenly distributed to the perimeter of the support area defined by the base member.

Abstract: A walker to assist physically impaired persons in ascending and descending stairs, has two rear legs pivotally attached to two front legs. When the walker is in use, the rear legs are locked against any pivotal movement; when stairs are to be negotiated, a locking member is released to permit relative pivotal movement of the rear legs in respect to the front legs. Thus, the front and rear legs can be placed on the staircase. After this has been done, the legs again are locked into position. The walker maintains this relative position so that the person using it may negotiate the stairs. The locking member is in the form of a toothed substantially circular gear and spring biased bolt.

Abstract: A dual handled walking-assist and uprisal-assist device is disclosed having the handles spaced at a predetermined distance to provide a stable structure for rising from and lowering to a seated position, in addition to serving as a walking aid.

A second handle or second pair of handles are spaced a preselected distance from the first handle or handles and at a preselected distance from the bottom of the device. An infirmed user can use the second handle or handles as a grip to push against when the user is rising from a chair. The second handle or handles are connected to one or more load-bearing shafts and the geometrical centers of the handles are positioned relative to the load-bearing shafts to provide a stable structure when used for uprisal and walking.

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.

Patients of this type generally have one strong side of their body and one relatively weak side. Many patients have suffered from a stroke. The hemi-wheeled walker comprises an upright segment having a lower base portion extending parallel to the side of the user, with a handle at an upper portion thereof. The upright segment is a adapted for low force movement across a support surface when the user is supported on his strong side and adapted for gripping engagement with the support surface when the patient requires additional support when he is primarily supported by his weak side. A stabilizing segment is provided to one side of the upright segment and has at least one wheel at a point of contact of the stabilizing segment with the support surface.

Abstract: A pivoting tray is provided for a walker.

Moreover, the mounting bracket is symmetrical for use on both the right-hand and left-hand sides of the walker, thereby reducing manufacturing costs and inventory.

Abstract: A controller for wheeled vehicles includes a mechanism which selectively shifts the vehicle between a mobile and a stable state. The vehicle may be a walker for easing an operator's efforts in walking and includes a selectively actuable stabilizer which fixes the position of the walker or releases it for rolling motion, thus providing a stable state or a mobile state, respectively. An actuator such as a button, pressure sensor, or lever, electrically and/or mechanically actuates a stabilizer brake mechanism to engage or release the brake and thereby allow the walker's mobility to be controlled when the actuator operates the brake to stabilize or to slow the motion of the walker. Preferably, lift applied to the vehicle itself releases the brake and allows mobility. The actuator may control an electrically actuated braking mechanism, in response to a sensor such as a strain gauge that may be adjusted to the needs of the patient; alternatively, lifters may be provided to act in response to the lifting force.
