Exercise devices having damped joints and related methods

摘要

An exercise device may comprise at least one joint. The at least one joint may comprise at least one first surface positioned adjacent to at least one second surface, the at least one second surface movable relative to the at least one first surface at at least one interface. A damping grease having a dynamic viscosity greater than about 100 Pascal seconds at standard temperature and pressure may be positioned at the at least one interface between the at least one first surface and the at least one second surface of the at least one joint.

1. An exercise device comprising:
a frame; a first foot support member connected to a central rotating member and comprising a central region mechanically constrained to follow an ovoid path; a second foot support member connected to a central rotating member and comprising a central region mechanically constrained to follow an ovoid path; a first swing arm coupled to a first side of an upper portion of the frame by a first hinge joint, a first end of the first swing arm comprising a handle and a second end of the first swing arm coupled to the first foot support member via a second hinge joint; a second swing arm coupled to a second side of the upper portion of the frame by a third hinge joint, a first end of the second swing arm comprising a handle and a second end of the second swing arm coupled to the second foot support member via a fourth hinge joint; at least one of the first hinge joint, the second hinge joint, the third hinge, and the fourth hinge joint comprising at least one first surface positioned adjacent to at least one second surface, the at least one second surface movable relative to the at least one first surface at least one interface; a damping grease having a dynamic viscosity greater than about 100 Pascal seconds at standard temperature and pressure positioned at the at least one interface between the at least one first surface and the at least one second surface of the at least one joint.
