Abstract: An adjustable lamp includes a base, a pole, a cantilever member, a light bulb assembly, and a lamp shade. The pole is attached to the base. A pole opening is formed through substantially a first end of the cantilever member which is sized to slidably receive the pole. An assembly opening is preferably formed at a second end of the cantilever member for attaching the light bulb assembly to the cantilever member. The light bulb assembly preferably includes a light bulb socket, a light bulb, a spacer, and an electrical cord. The bottom of the light bulb socket is inserted through the spacer. A bottom of the light bulb socket is inserted through the assembly opening and fastened to the cantilever member. The light bulb is screwed into the light bulb socket. A lamp shade is attached to the adjustable lamp. The position of the light bulb is adjusted by lifting up the cantilever member, sliding the cantilever member to a desired position, and finally lowering thereof.

Abstract: An adjustable crutch has two vertical supports with an upper arm rest and a third, vertically adjustable lower support. The lower supports fixes the overall height of the crutch. The independently moved hand grip is easily adjustable to provide proper spacing between the crutch's hand grip and arm rest based on the user's arm length. This contruction requires only a two-step adjustment process which may be accomplished individually by the user.

Abstract: A hinge element consists of a tube connector attached to the end of a tube, the end of the tube connector having a notched head portion. Pivotably attached to the notched head of the connector is a bracket element having a spherically shaped, notched end which engages the ends of a spring and a limiting wire. The limiting wire and spring are attached at their other ends to a cross bar and a second tube in which the hinge element and the first tube may slide coaxially. A hand grip is also disclosed which consists of a central grip portion with two cylindrical parallel holes having slits on the outside thereof. At the outer edges of the slits are ribs which, when the outer portions of the grip are tightened, focus the compressive forces generated by the tightening toward the tube portions, thereby creating a strong frictional hold. The hinge and grip configurations are found in a bitubular orthopedic crutch having three sections.
