Abstract: A manually powered elliptical motion exercise apparatus includes a floor-supported frame, a crank mechanism defining a first axis, and radially-extending crank arms. A pair of elongated pedals include foot-receiving platforms for supporting a user standing thereon and are coupled to the crank mechanism by crank coupling structures such that each crank coupling structure traverses a generally circular path about the first axis as the pedals are manually operated by a standing user. A pedal guide defines a second axis that is fixed with respect to the frame, and each pedal is constructed and arranged to be supported on the guide for pivoting movement with respect to the second axis and to accommodate a horizontal extent of movement imparted to the foot-receiving platforms by movement of the elongated pedals around the first axis so that the foot-receiving platforms traverse an elliptical path of motion simulating natural striding foot movements.

Abstract: A multi-position exercise bench includes an elongated central frame member to which a back support having a head end and a seat end is attached and to which a seat structure is attached near the seat end of the back support structure. The seat structure is pivotal between an upright position extending transversely from the central frame member and a lowered position in which a top surface of the seat structure is at an obtuse angle with respect to a top surface of the back support structure and is selectively securable in a plurality of different positions. The central frame member is supported by a first leg attached at one end of the frame member, a second leg extending transversely from an intermediate portion of the central frame member opposite the seat structure, and a third leg pivotally attached to an end of the central frame member opposite the first leg.

Abstract: A flexural exercise device includes two oppositely-extending arm structures connected to one another by a resilient element, preferably in the form of a coil spring, disposed therebetween to which the inner ends of the arm structures are attached. The middle resilient member is covered by a padded neck roll. Each arm structure preferably comprises a tubular element extending away from the central resilient member and having an initial straight portion and a laterally bent handle portion at the end of the straight portion. The laterally bent handle portion provides a hand-gripping structure, and the transversely bent portions of each of the arm structures are bent so that the hand-gripping portions thereof are directed in directions generally toward one another so that a free end of each hand-gripping portion is disposed inwardly of an outermost extremity of the respective arm structure. The arm structures are preferably bent, steel tube construction and are preferably covered with a foam padding layer.

Abstract: An exercise apparatus includes a frame, a seat for a user, and a feet engageable moving mechanism carried by the frame and including a pair of feet engaging members. The feet engaging members present different foot receiving surfaces to be engaged by the feet of a user for providing different leg movements depending on the position of the user and the user's legs. First foot receiving surfaces support a user in a standing position and move the user's feet in a generally elliptical path of motion simulating a natural foot striding. Second foot receiving surfaces are spaced further away from the seat than the first foot receiving surfaces and have vertical components enabling a seated user to extend his legs forwardly and exert, with the bottom of his feet, forces having substantial horizontal components to the feet engaging members to drive the feet engageable moving mechanism against its internal resistance.

Abstract: A motorless manually operated treadmill exerciser comprising a frame structure supporting a motorless manually operated treadmill assembly and a retardant assembly constructed and arranged to establish a retardant to the continued movement of the endless track of the treadmill assembly when the user desires to slow the walking or running speed or disembark.

Abstract: An exercise machine has a first bar releasably coupled with a first cam pivotally mounted generally above and behind a seat mounted on the frame of the exercise machine. A second bar is connected to an arm assembly which is releasably coupled to a second cam pivotally mounted generally below the seat. Each cam has a means for resisting rotation of the cam mounted between it and the frame. Movement of either the first bar or second bar rotates its associated cam against the resistance of its associated resistance means. The starting position of each bar is adjustable and may be selected by coupling the bar with its associated cam in one of a plurality of fixed resting positions. Each cam may rotate in either direction about its pivot position. Accordingly, each bar may be moved from its selected starting rest position in either direction to impart rotation of its associated cam against selected resistance.

Abstract: A pedal-type exerciser includes a first drive assembly having a first horizontal axle mounted rotatably on a rear end portion of a base, first and second drive wheels mounted securely and coaxially on the first horizontal axle, and a pair of first crank arms mounted securely on opposite ends of the first horizontal axle. A second drive assembly has a second horizontal axle mounted rotatably on a front end portion of the base, a third drive wheel mounted securely on the second horizontal axle, a transmission chain trained on the second drive wheel and the third drive wheel, and a pair of second crank arms mounted securely on opposite ends of the second horizontal axle. Each of a pair of elongate pedal members has a front portion with a distal end of a corresponding second crank arm mounted pivotally and slidably therealong, and a rear portion mounted pivotally on a distal end of a corresponding first crank arm.

Abstract: A multi-compartment bird shelter that may be assembled with a minimum of mechanical fasteners and which may be assembled as a multi-tiered structure is disclosed. The shelter is supported, by a support flange, on a vertical pole and includes a plurality of individual compartment modules that are pie shaped with vertical divergingly spaced walls and a bottom surface. A spacer element place coaxially over the pole is larger than the pole so as to define a gap between the pole and the spacer element. The spacer element rests upon the support flange, and individual compartment modules are coupled to the pole by inserting a hook structure of the module into the gap defined between the pole and the spacer element. A plurality of like sized and shaped modules are arranged around the pole in side-by-side fashion and are similarly coupled to the pole so as to define a tier of compartments. Subsequent tiers of compartments may be similarly assembled atop existing tiers.

Abstract: An exercise apparatus including a base structure comprising a fixed lower body exercise platform and a pair of elongated upper body exercising units is disclosed. The units are mounted to the base structure by mounting structure that enables the units to be moved by a user against a yielding resistance in any direction with respect to a center in conjunction with the user stepping onto or off of the platform in any direction while performing an exercise thereon. The elongated upper body exercising units preferably include two telescoping exercise poles to be grasped by opposite hands of the user and capable of both oscillating and reciprocating upper body exercising motion. A variable volume air chamber is defined in an annular gap between coaxially arranged inner and outer members of the telescoping exercise poles and a restricted air passage communicates with the air chamber.

Abstract: A motorless manually operated treadmill exerciser including a frame structure having a plurality of transverse rollers at a bottom side thereof and a track mounted around the transverse rollers for movement by a user walking or running thereon. A wind resistance retarding assembly is mounted on the frame structure in front of the track which includes a series of fan blades rotatably driven by the rollers through a pair of spaced belt and pulley assemblies. The wind resistance produced by the turning fan blades is directed at the user and serves to retard the movement of the track when the user desires to slow the pace or disembark.

Abstract: An exercise machine has a-first track and handlebar assembly for simulation of cross-country skiing and a second track and handlebar assembly for simulation of downhill slalom skiing. The first track assembly has first and second elongate, parallel rails. A footpad engages each rail and is adapted to move along the length of its respective rail. A pair of handlebars are pivotally mounted at a location near one end of the first and second elongate rails. The second track has first and second arched rails. A platform is releasably mounted on said first and second arched rails and is adapted to move from one end of the rails to the other. A handlebar is provided for grasping during use of the platform for exercising. Resiliently flexible tension bands or chords are used to resist movement of both the first and second footpads and the platform.

Abstract: A multiple function exercise apparatus comprises a frame for supporting a resistance assembly such as a guided weight assembly. A cam is pivotally mounted on the frame and is operably connected to the resistance assembly. A handlebar may be attached to said cam in one of a plurality of fixed resting positions. In one mode of operation, movement of the handlebar in a first direction causes the cam to pivot in a first direction thereby moving the resistance assembly from its resting position. In another mode of operation, the movement of the handlebar in a second direction opposite the first direction causes the cam to likewise pivot in a second direction opposite the first rotational direction thereby moving the resistance assembly from its resting position. In yet another mode of operation, the cam may be locked in a fixed position.
