Abstract: An exercise machine for assisting a user in performing chin-ups and dips includes a pair of handles attached to a frame and a kneeling platform operably connected to the frame by a four-bar linkage. The pair of handles may be a pair of chin-up handles attached to an upper portion of the frame or a pair of dip handles attached to a medial portion of the frame. The four-bar linkage moves the kneeling platform along an arcuate path of travel corresponding to the natural arcuate path of the center of gravity of the user during a chin-up or a dip so that the kneeling platform remains beneath the user's center of gravity during performance of a chin-up or a dip. The four-bar linkage also preferably maintains the kneeling platform in a horizontal orientation. A selectable number of weights urge the kneeling platform upward so that the user may lift his body with his arms while applying a force less than his own body weight.

The apparatus is further capable of providing variable amounts of assistance.

Abstract: A bar preferably formed of tubular aluminum is formed to have a yoke and extensions for holding the shoulders of a user in a neutral position for exercising. Trunk twists and bends may be performed using the bar to maintain positions of the arms and torso for maximum effectiveness of the exercises. The bar is configured for adding weight inside or outside and particularly at its ends for increasing the rotational moment of inertia of the bar to give the effect of greater weight. End caps are configured to conveniently secure weights within or around the bar, by friction and threaded engagement. Weight materials include water, shot, cylinders, wheels and annuli configured as dead weights. The weight greatly enhances the moment of inertia when the bar is in motion during exercises, and can also be used with a leverage advantage to increase its effectiveness over conventional dead weights.

Abstract: A hand exerciser of a type having two hand grips squeezed together form an open position against the resistance of a spring and then released to again assume their open position which is achieved using a movement-limiting link, in which the link is limited in descending movement along length positions of the spring which unavoidably occur when the hand grips are together to a position which obviates "catching" on the spring that would impede opening movement. The link is held in a position where the spring connecting structure is angular rather than straight, which is less vulnerable to "catching".

Abstract: An endotracheal tape for adhesively securing an endotracheal tube in position is disclosed. The tape consists of a single piece of 1 inch wide tape having first and second opposite ends split into two identical sections. A single short, non-stick piece is centered along the length of the tape and the tape is rolled onto two plastic tubes from each of the first and second ends. To dispense the device, the tape is unrolled slightly from the tubes to expose the short non-stick piece and the piece is placed against the back of the patient's neck. The tape is then completely unrolled and the upper halves of the split ends are affixed above the patient's nose or mouth and the lower halves of the split ends are wrapped around an endotracheal tube.
