  • Patent number: 8235063
    Abstract: Provided is a crutch that may be collapsed for storage and shipment, adjustable for different users and mitigates the affect of the enrich striking the ground. A saddle support surface is coupled to two rails that extend and slide through a handrail and a wishbone. The rails may be secured with respect to the handrail and wishbone in a variety of positions, enabling the distance between the support surface and the handgrip and the length of the crutch to be adjusted. In addition, the rails may be positioned in the handrail and wishbone such that the support surface fits against the handrail and the handrail against the wishbone. A shock tube extends from and slides through the wishbone and may be secured in a variety of positions to adjust the length of the crutch to account for different users and to minimize the length for storage and shipment.

  • Patent number: 8215652
    Abstract: The mobilizer consists of an open, inverted ā€œUā€ shaped frame when view from above with the legs or the ā€œUā€ pointed towards the rear. Pivoting caster wheels are attached to the front lower corners and rear wheel support arms extend rearward and curve downward each bearing a smaller non-pivoting wheel. Two vertical upright support members rise from the frame and are equipped with height adjustment mechanisms. Horizontal arm support assemblies, each with a hand grip and brake handle are attached to the upper ends of the support members. The user is supported by his elbows and shoulder girdle resulting in decompression of his spine. The arm support assemblies can be pivoted 180 degrees so that the grip portions and the hand brake levers face the rear of the mobilizer at about waist height. This allows the user to stand and grasp the handles as he walks forward.

  • Patent number: 8215863
    Abstract: A locking mechanism includes a support rod, inserted into a first unit shaft at a first end thereof and locked to a second unit shaft at a second end thereof, with threads formed around the outer circumferential surface thereof; and a pressure locking unit movably engaged with the threads of the support rod and having longitudinal slits formed to open in one direction and at least two pressure parts formed in a longitudinal direction. The locking pressure of the pressure locking unit is imposed on the unit shafts at multiple longitudinally spaced points, thus dispersing or distributing the locking strength in the longitudinal direction and increasing both the locking strength and the resistance against both longitudinal compressive force and longitudinal tensile force, thereby preventing the locked unit shafts from suddenly slipping towards each other.

  • Publication number: 20120160286
    Abstract: A stick that is excellent in shock absorption and is also excellent in stability is provided. A stick body is provided with a telescopic extension pipe formed by fitting an outer tube and an inner tube together in a nesting manner. Inside the extension pipe, a velocity-dependent damper that damps the relative sliding movement between the outer tube and the inner tube, and a compression coil spring that concentrically fits onto the damper and urges the extension pipe so as to be extended are connected in parallel. According to such a stick, the shock transmitted to the hand can be mitigated as the compression coil spring contracts upon landing. Also, since the damper suppresses unwanted vibration of the extension pipe, the length of the stick quickly becomes stable after landing, allowing the user to keep stable balance with the stick.

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.

    Abstract: A height adjustable crutch includes a single tube member, a foot grip, an underarm support, and a handle. The single tube member has a central axis along which a main member, a telescoping top member, and a telescoping foot member are aligned. The top member is adjustable relative to a top end of the main member. The foot member is adjustable relative to bottom end of the main member. The foot grip is fixedly attached to the foot member, and the underarm support is fixedly attached to a top end of the top member. The underarm support is generally perpendicular to the central axis of the single tube member. The handle is fixedly attached to the main member and is offset from the central axis of the single tube such that a gap separates a central area of the handle and the main member.

  • Patent number: 7487788
    Abstract: The invention is for a handle assembly for an adjustable crutch having two upper tubes each of which slides inside one of two lower tubes to adjust the height of the crutch. The handle assembly has a body, a lever attached to the outside of the body; and two locking pins positioned inside the body. Each locking pin is mechanically coupled to the lever and each locking pin is normally biased through tube holes formed in the upper tubes and through tube openings defined in the lower tubes to prevent the sliding of the upper tubes inside the lower tubes. The depression of the lever causes the locking pins to retract from the tube holes and the tube openings such that a user may slide the upper tube inside the lower tube to change the crutch height.
