Abstract: A variable stride exercise apparatus is described. The apparatus may include a frame. A crank system may be coupled to the frame. The crank system may include crank rollers. In certain embodiments, arm links may be coupled to the frame. The apparatus may include foot members that travel in multiple paths. The foot members may be coupled to the arm links. The foot members may be coupled to the crank system through cam devices. The crank rollers may be located below the foot members such that at least a portion of a user's foot passes above the crank roller during use of the apparatus. A user of the apparatus, by varying the user's stride, may selectively vary a path of the foot members. The foot members may be cross coupled so that the left foot member moves in opposition to the right foot member.

Abstract: A variable stride exercise apparatus is described. A variable stride exercise apparatus may include a frame. A crank system may be coupled to the frame. A movable member may be coupled to the crank system. The movable member may travel in a substantially curvilinear path during use of the apparatus. A foot member may be coupled to the movable member. The foot member and the movable member may allow a user of the apparatus to selectively control the path of the foot member. The foot of the user may travel in a substantially curvilinear path during use of the apparatus. At least a portion of the apparatus may remain substantially stationary during use.

Abstract: In certain embodiments, an apparatus for exercising may include a frame and a first movable member and/or a second movable member. The first movable member may translatably move along a first roller coupled to the frame. The second movable member may translatably move along a second roller coupled to the frame. The exercise apparatus may include a crank system having a crankshaft axis. Ends of the movable members may be pivotally coupled to the crank system such that the movable members move in a substantially orbital path about the crankshaft axis during use of the apparatus. First and second pivotal linkage assemblies may be used to orient the feet of a user of the apparatus during operation of the apparatus such that each foot of the user follows a closed path.

Abstract: In an exercise device having an elongate frame, a user can exercise by engaging four slides, one for each limb. The slides travel along parallel paths, enabling reciprocating motion. Each slide connects to a chain or cable segment to enable reciprocating cable motion. The motion is coupled to elongate cables (one or more) which connect to gears, causing reciprocation of clutches, thereby impulsing a fly wheel in a single direction and causing rotation.

Abstract: A game racquet has a composite metal-plastic frame intermediately defining a head and having opposite ends within a handle, there being external plastic strips laterally located on the head, a wide strip around the outer part of the head and narrower strips extending from opposite ends of the wide strip into the handle, and the handle comprising a housing wherein the frame ends are secured together and to the housing and wherein the remaining space is occupied by foamed polyurethane.

Abstract: A safety-pressure-vacuum relief valve assembly for vehicle fuel tanks and the like which is adapted either to be mounted at an external point on the vehicle and connected to the interior of the tank by a conduit or to be a part of the cap for the conventional tank filler neck. The assembly comprises a fitting having an upwardly facing annular flange area concentric with the axis of the fitting, a circular plate concentrically resting on the flange, an inverted cup providing a peripheral skirt having a concentric and peripherally extending shoulder above the flange, the cup and fitting being secured against axial separation to capture the said plate therebetween, and an annular flexible gasket having an outer peripheral portion gripped between the plate and the shoulder of the cup and an inner peripheral bead engaging the upper surface of the plate normally to close pressure relief openings in the plate.
