Abstract: A versatile, multi-purpose and portable continuous loop exercise apparatus designed so as to enable users thereof to exercise multiple body parts through resistive training. The unique continuously looped structure enables users to perform various exercises. The continuous loop exercise apparatus may be utilized in combination with the floor, on the chair, or can be placed on a table or countertop without the requirement to reconfigure or reassemble the product. The one-piece curved design allows users with different body builds to perform the same exercises appropriately by changing the holding user-to-apparatus contact positions rather than by adjusting the dimensions of the equipment.

Abstract: A valve door for a seal cylinder comprises a lid having first and second surfaces and a connecting means connecting the lid with an actuating mechanism, the connecting means distributes forces from the actuating mechanism across a portion of the first lid surface in order to bias the lid to a closed position. A force directing member is attached to the first lid surface, the force directing member being adapted to distribute force from the connecting means over a portion of the lid surface, thereby maintaining a positive seal and reducing lid deflection.

Abstract: An instrument includes an instrument body having an opening at one end. A valve is mounted within the instrument body, the valve having an opening at one end. A lid is integrally molded with the valve and hingedly movable with respect to the valve opening. An actuating arm is operatively connected to the lid, the actuating arm transmitting forces from an instrument movement mechanism to the valve door under both tension and compression. As a result, the lid is opened and closed substantially solely by the actuating arm.
