The at least one pad member may have an attachment opening that includes a first portion sized to receive a shaft portion of the support member, and a second portion sized to receive a retaining portion of the support member, the retaining portion being larger than the shaft portion of the support member.

Abstract: Moveable exercise benches are disclosed. In one embodiment, an exercise machine includes a load, an exercise station, and a force-transferring assembly operatively coupling the exercise station and the load. A moveable support is positioned proximate the exercise station and is adapted to support a user during an exercise. The force-transferring assembly is adapted to allow the moveable support to move without decoupling the force-transferring assembly from the exercise station and to allow use of the exercise station at any location of the moveable support without adjustment. The force-transferring assembly may be a cable-and-pulley assembly. In an alternate embodiment, the force-transferring assembly may be adapted to apply a counter force on the moveable support that at least partially counters a reactive force applied by the user to the moveable support during the exertion of the exercising force.

Abstract: Actuator assemblies for adjustment mechanisms of exercise machines. In one embodiment, an actuator assembly includes a connecting member having a first end attached to the adjustment mechanism and a second end, a shaft rotatably coupled to the exercise machine proximate the second end, an actuating handle attached to the shaft, and a coupling member attached to the second end of the connecting member and having an engagement portion contacting an actuating portion of the shaft. As the shaft is rotated, the actuating portion of the shaft pushes the engagement portion of the coupling member, tensioning the connecting member and actuating the adjustment mechanism. The actuator mechanism advantageously reduces wear and breakage of the connecting member. In another embodiment, the shaft may be rotated in either a forward or an aft direction, improving the convenience of the actuator assembly for the user.

The first and second cross-sectional directions may be approximately orthogonal. Similarly, at least one of the convex and concave shapes may have a constant radius of curvature.

Abstract: Cable-and-pulley devices having intermediate tension isolators for exercise machines. In one embodiment, a cable-and-pulley device includes a cable attached to a load and to a user interface, and operatively engaged with a main pulley positioned over the load, a floating pulley, and an end pulley proximate the user interface. A second user interface is attached to the floating pulley. A tension isolator is positioned on the cable at an intermediate position between the end pulley and the floating pulley so that a training force applied on a second user interface draws the tension isolator into contact with the an isolator stop. In one embodiment, the isolator stop is an intermediate pulley. Alternately, the isolator stop is a catch projecting from a frame of the exercise machine. The tension isolator effectively divides the cable into a tensioned portion and an isolated portion, thereby reducing the amount of cable that is stretched during use of the second user interface.

Abstract: Apparatus and methods for exercise machines having balancing loads. In one embodiment, an apparatus includes a load guide pivotable through at least one plane of freedom, a load slideably engaged with the load guide, a lift arm having a first end coupled to the load guide, and a cable-and-pulley device. The cable-and-pulley device is operatively coupled to the load and to the lift arm so that a training force applied to the lift arm induces a lift force on the load. The exercise machine requires the user to balance the load as the load is raised, providing a more enhanced workout. In alternate embodiments, the load guide may include at least one rocker engageable with the floor surface, or may be pivotably coupled to a support frame (or base) so that the load guide does not contact the floor surface. In another embodiment, the load guide may include a base having a convex surface engageable with the floor surface, the load guide being pivotable in any direction.

Abstract: An exercise station for use in performing leg exercises has a bench on the front of which an exercise unit with leg engagement arms and a load unit connected to a loaded cable are swing mounted on a horizontal swing axis. A two-bar linkage is pivotally connected to the units and has over-center extended and folded positions when the exercise unit is in raised and lowered exercise positions, respectively, whereby exercising swing movement of the exercise unit also swing moves the load unit by way of the linkage.

Abstract: A multiple station weight lifting type exercise apparatus having cabled linkage and direct lifting capabilities is disclosed. The apparatus is characterized as having a plurality of exercise stations located about a base platform and a single weight stack being movable in a conventional manner through direct and indirect forces applied thereto by the various exercise stations. Each station generally has several apparatus connectable to one or more cables that are operatively linked to all other stations and effect movement of the weight stack preferably by a single cable when any cable undergoes tensioned movement. In addition, at least one station directly imparts movement of the weight stack by means of non-cable linkage. The non-cabled linkage or direct lift of the weight stack is carried out by providing for a translation assembly to be located in operative engagement with the weight stack to which the cable, operatively linked to other stations, is anchored.

Abstract: A multiple inclination exercise bench having a torso supporting assembly and a seat supporting assembly is disclosed wherein the elevation by a user of the torso supporting assembly causes the elevation of the seat supporting assembly. The invention is characterized as having a torso supporting assembly mechanically linked to a seat supporting assembly. In preferred form, the torso supporting assembly is pivotal at its proximal end about a point associated with the bench and has associated therewith at least one cam plate. A lever or rocker arm is pivotally located adjacent to the cam plate and has a cam follower attached thereto at one end, and a seat support member at the other end. The seat support member supports the distal end of the seat supporting assembly where the proximal end is pivotally located on the bench. A support member is associated with the torso supporting assembly to maintain a desired inclination thereof.

Abstract: An exercise machine for performing leg extension and leg curl exercises has a seat from the front of which a swing member depends. A swing link is pivotally connected near the lower end of the swing member and supports a pair of laterally extending pads. A rearwardly directed force is applied to the swing member to act in opposition to forward movement of the swing member and swing link when an exerciser pushes against one of the pads with one of his (her) legs when the exerciser is seated (leg extension exercise) or is standing facing rearwardly with the seat swung upwardly to an upright position.

Abstract: An exercise device, as for example, the wing on a butterfly exercise machine, is arranged to be moved from an at rest position in an exercising direction in a range of travel counter to a load and to be returned to the at rest position by the load. An adjustment mechanism between the exercise device and load selectively adjusts the start of the travel range by movement of the exercise device in a direction opposite from the exercising direction. The adjustment mechanism includes a rack and pawl arranged to be engaged with one another when the exercise device is moved in the exercising direction.
