  • Patent number: 5356360
    Abstract: An adjustable lever arm--variable resistance cam assembly employing a cam for producing therefrom a variable resistance force when a constant resistance force is applied thereto and in which the lever arm may be initially positioned at a range of angular positions without thereby affecting the variable resistance force produced by the cam at each particular angular position of the lever arm upon rotation thereof. The adjustable lever arm--variable resistance cam assembly may be employed in a weight lifting machine or device of the type having a rotating lever arm for application of weight lifting force by the user. The assembly allows the user to angularly adjust the initial position of the lever arm in relation to the axis of the cam and, nevertheless, maintain the cam in appropriate relation with the constant resistance force. The variable resistance force produced by the cam will then not vary with respect to positioning of the lever arm as rotated during exercise.

  • Patent number: 5354248
    Abstract: An exercise apparatus having a vertically movable weight, and an input pedal mechanism engaged by the user to input an input power with a unidirectional exercise force at a user-selected velocity for moving the weight upward. Also included is a brake applying a negative braking power with a unidirectional braking force opposing the exercise force. The braking power has a braking velocity for permitting downward movement of the weight. A brake controller controls the application of the brake to maintain the braking velocity at a selected constant velocity for at least a selected portion of the user's exercise time. A differential member is coupled to the weight and receives the input power and the braking power. The differential member determines a differential between the user-selected velocity and the selected constant braking velocity, and applies the resultant to movement of the weight.

  • Patent number: 5350343
    Abstract: A multi-functional hand-gripping device is disclosed. The device has a gripping pad which includes a hand pad and a wrist pad. The hand pad is sized and shaped to align with the hand surface of the user and to improve the grip on a weight bar when a bar is grasped. The hand pad is also adapted to be curved away from the hand surface of the user and wrapped around an object to be grasped. A securing strap secures the gripping device to the wrist. The securing strap preferably uses hook and loop securing means. A support strap centrally disposed in the hand pad provides extra support for lifting heavy objects. The gripping pad is preferably constructed of neoprene, and has a non-slip surface on one side and a second non-grip surface on the other.

  • Patent number: 5350346
    Abstract: A weight bench having a slidable seat construction includes a two piece slidable bench which is pivotally connected to the frame of a weight bench. A sleeve, designed to travel along a frame member, supports the seat portion of the bench at a pivotal attachment and by an angle adjusting bracket mechanism. A back rest portion of the bench is pivotally attached at one end thereof to the sleeve. The other end is connected to the frame by a support which is pivotally attached to both to the frame and the underside of the back rest portion. The sleeve is lockable in a given position along the length of the frame member providing support therefor. Sliding movement of the bench produces simultaneous adjustment of the inclination of the back rest due to the double pivotal attachment of the support. The sliding seat assembly is particularly adapted for weight benches having uprights with barbell supports.

  • Patent number: 5350344
    Abstract: An exercise machine includes a weight stack with a plurality of separate weights and a lift bar for vertical movement with the stack. A pin assembly removably secures a desired portion of the weight stack to the lift bar for vertical movement therewith so that the total weight carried by the lift bar is determined by the portion of the weight stack removably secured to the lift bar by the pin assembly. The pin assembly includes at least one pin operated by a two-position or double action actuator, each pin being movable by its actuator over a predetermined stroke. Each actuator includes a first device for positively moving the pin to an extended position to removably secure a portion of the weight stack to the lift bar and a second device for positively moving the pin to a retracted position in which the corresponding of the weight stack is free of the lift bar.

  • Patent number: 5346448
    Abstract: A free weight lifting system utilizes a lifting bar with an inboard region to be gripped by a weight lifter and opposed ends which can receive and support one or more weights to be lifted. A first pair of spaced apart upright members are positioned in a first longitudinally extending plane and a second pair of spaced apart upright members positioned in a second longitudinally extending plane, the first and second planes being spaced apart and generally parallel. A first yieldable cord extends between the first pair of upright members and a second yieldable cord extends between the second pair of upright members. In one mode of operation, the lifting bar is positioned beneath the elastic cords. When it is raised by the weight lifter, an upper surface of the bar is engageable with the yieldable cords at spaced locations such that progressively increasing resistance is imparted to the weight lifter. In another mode of operation, the lifting bar is positioned above the yieldable cords.
