  • Patent number: 4607840
    Abstract: A device for mounting weight training plates at an extended distance beyond the hand of the user applies selective leverage against the user's arm. The device gains mechanical advantage and thereby increase the effective weight applied without requiring actual increase in the number or size of the weight training plates used. The device includes a frame having a handgrip and a bar for mounting weights outward of the handgrip. First and second braces are situated toward a rearward end of the frame for engaging opposite sides of the user's forearm. One brace is situated between the handgrip and remaining brace to engage the forearm on one side surface. The remaining brace is situated near a rearward end of the frame to engage the user's forearm at a point rearward of the first brace and adjacent the elbow. The braces cooperate with the handgrip to maintain position of the weights at an extended location beyond the user's hand.

  • Patent number: 4595198
    Abstract: An exercise machine primarily used in exercising and strengthening muscles and ligaments not normally affected by the standard dynamic and/or isometric approaches. The machine causes the user to work against a centrifugally operated brake which increases the resistance to movement as the rate of movement increases. A horizontally disposed lever including a stirrup is rotated about a vertical shaft by the foot and leg of a user, and the shaft is functionally connected to a speed increasing mechanism and its rate of rotation is regulated by a centrifugal brake. The amount of effort being expanded to overcome the brake resistance is displayed by a simple linkage from the brake mechanism to an easily visible indicator.

  • Patent number: 4595197
    Abstract: An exercise device comprises a pair of wheels on opposite ends of an axle, and a pair of foot-receiving stirrups on the axle between the wheels. A user positions his or her feet in the stirrups, assumes a basic push-up position on a support surface and exercises either by walking along the surface on the hands, rolling the feet behind, or by maintaining the hands in stationary position and using the body to roll the wheels toward and away from the hands.

  • Patent number: 4593674
    Abstract: A compound archery bow of simplified construction includes a bowstring secured intermediate its ends to eccentrically pivoted cams mounted at the outer ends of the limbs secured to the opposite ends of a handle member. A control cable connects each cam pivot shaft, and therefore each limb, to a laterally projecting post on a lever mounted pivotally on the end of the handle member that secures the opposite limb. The end segments of the bowstring are trained around the cams and through the diametric center of each cam wherein the segments are secured. Each terminal end portion of the bowstring end segments is secured either to a winch located on the lever mounting the associated cam, or directly to said lever. The connection of the limbs to each other through the control cables and the bowstring end segments secured to the levers balance the flexure of the limbs relative to each other as well as the rotation of each cam as the bowstring is drawn back.

  • Patent number: 4591149
    Abstract: A leg exercise device is provided which is especially useful for developing the lower leg muscles associated with the calf. The device is defined by a base support connected to a pair of upwardly extending tubular handlebars. A weight carriage is slidably mounted on the handlebars in a manner that allows a seated exerciser to place his foot under the carriage and uplift the carriage by lifting the front of his foot. A pair of weight bars are also connected to the weight carriage in order to slidably accommodate a standard set of weights. The device discloses an upper leg exerciser in which an upper bar assembly is attached to the front of the weight carriage and the handlebars are pivotally connected to the base support. An exerciser sits in front of the device, and adjusts the handlebars close to the top of his knees. When the knees are raised, the weight carriage slides up the handlebars.

  • Patent number: 4589658
    Abstract: A weight lifting apparatus is shown to enable the user to perform power squat lifts to develop leg strength throughout the hips, thighs, and calf leg muscles, while at the same time eliminating back injuries to the user. The user is provided with a waist harness having front and rear straps suspended from a heavy belt down between the legs of the user. The belt has interior padding that extends above the top edge and below the bottom edge of the belt. The harness is connected to a weight holder by an adjustable chain so that all of the weight is carried by the lower half of the body. The weights remain below the user's body, and the center of gravity of the weights remains below the user's center of gravity. This apparatus is formed as an elevated rack having a pair of elongated platforms separated by a well section. The user straddles the platforms and the weights remain within the well section.

  • Patent number: 4575076
    Abstract: An arm wrestling machine including an operating arm pivotally mounted on a base and two assemblies for exerting forces on the operating arm urging the operating arm toward a vertical position. One assembly includes a spring connected between the operating arm and a spring support mounted on a screw for linear movement toward and away from the operating arm so that such assembly provides an adjustable, continuous force on the operating arm. The other assembly includes a pneumatic cylinder connected between the operating arm and the base and intermittently receiving bursts of compressed air from a valve that is mounted on the operating arm so that the case of the valve moves with the operating arm and having a weight attached to the valve member of the valve so that movement of the operating arm intermittently opens the valve.

  • Patent number: 4574766
    Abstract: A joint structure between each limb and a handle riser of a take-down type archery bow is described employing a plug-socket engagement based upon a two position support. The first position support is located near the mouth of a handle riser socket and enables the change in angular position of the limbs with respect to the handle riser by the replacement of a pair of flat spacers of predetermined thickness. The second position support, being unaffected by the first position support, is located near the bottom of the socket for releasably engaging the plug end of the limbs in order to prevent accidental removal of the limbs from the handle riser socket.

  • Patent number: 4570608
    Abstract: An inertial archery bow stabilizer and vibration dampner is disclosed. A stud is rigidly embedded in the archery bow and has an energy disipating rod fixed to and projecting forwardly of the stud. The rod is received within an encapsulating sealed cylinder having an internal chamber filled with a viscous fluid in which the rod is disposed. At its outer end and externally thereof, the cylinder is provided with another stud to which the archer may afix a selected stabilizing weight. The stabilizer is effective to limit bow movement during arrow cast and rapidly dampen and attenuate energy released as characterized by dampened bow vibration.
