Abstract: A support system for use in adjusting the incline of exercising equipment such as treadmills is disclosed. The system includes a pair of linked support legs pivotally mounted to one end of the equipment's frame. A length-adjustable gas spring is pivotedly associated with the linked support legs and the treadmill. Control means are provided to adjust the orientation of the spring, thereby controlling the elevation of the exercising equipment and hence its incline.

Abstract: A multipurpose exercise apparatus may be assembled into a plurality of configurations and positioned in a plurality of orientations to perform a variety of exercises, including cross-country-skiing-type exercises and rowing-type exercises.

Abstract: A motorized treadmill has a right roller bracket and a left roller bracket with a tail roller interconnected thereinbetween. The brackets mate into the left extension and the right extension respectively of the treadmill frame. The treadmill frame is unitarily formed and is "U" shaped. The left and right roller bracket together with the tail roller secure the rear ends of the left and right extensions together and hold them in a spaced apart condition. in addition, belt guides are positioned to guide the lower stretch of the endless belt. The belt guides extend upwardly and inwardly and forwardly at preselected angles to minimize belt wear and belt noise in operation.

Abstract: An exercise apparatus for performing striding-type exercises is disclosed. The apparatus includes a pair of leg members depended from and rotatably associated with a pair of journals connected to a frame. Each of the leg members is fitted with a foot support. The leg members are mechanically associated one with another by a cable and pulley arrangement adapted for providing a reciprocative action of one by member opposite to that of the other upon a movement of either leg member.

Abstract: An exercise machine such as a rowing machine has a resistance system which consists of a fluid cylinder interconnected at one end to the movable block of a block and tackle which is selected to have a desired mechanical advantage to provide the desired resistance to movement of machine operation means such as the handle of the rowing machine. Adjustment structure provides for variable or adjustable resistance to movement of the block and tackle structure.

Abstract: An exercise machine has an electrical safety switch which switch includes a base with a switch actuator attached thereto. A paddle is rotatably attached to the base for movement toward and away from the actuator. The paddle has an upper element and a lower element to form a void therebetween. The lower element as an aperture through which the actuator passes when the paddle is depressed. Placement of an enabling card in the void obstructs the aperture and enables operation of the actuator between "on" and "off" positions by depression of the paddle. Removal of the enabling card prevents accidental actuation of the machine.

Abstract: A trampoline includes a sheet resiliently supported and tensioned by a substantially rigid frame through means of spring-like members positioned about the perimeter of the sheet. The spring-like members are connected to the sheet through means of a compressive fastener adapted to receive a turned-over edge of the sheet. The turned-over edge of the sheet defines a channel in which a filler, such as a cable, is placed. The fastener compressively retains the turned-over edge together with the cable.

Abstract: An exercise apparatus is provided having a frame for supporting a user mounted on the apparatus above a support surface such as a floor. A pair of leg members and associated foot supports depend from and rotatably associate with a pair of journals connected to the frame. A user stands on the foot supports and moves his legs in a striding-type reciprocating motion. A pair of handle members may also be associated with the journals to rotate simultaneously with their respective leg members. A reciprocation mechanism may force opposite rotation of the pair of leg members with respect to each other. Various resistance mechanisms may be adapted to the apparatus to offer resistance to the striding-type motion.

Abstract: The invention provides an exercise cycle with a stationary frame, a seat, a pedal mechanism, and a rotating wheel. Resistance is offered to the rotating wheel by an adjustable brake assembly. A handle bar assembly is pivotally mounted to the frame to move back and forth toward and away from the user positioned on the seat. A locking mechanism is associated with the handle bar assembly, so that with the locking mechanism in a first position, the handle bar assembly is precluded from pivoting. With the locking mechanism in a second position, the handle bar assembly is allowed to pivot toward and away from the user. A resistance mechanism is also associated with the handle bar assembly.

Abstract: A multipurpose exercise apparatus may be assembled into a plurality of configurations and positioned in a plurality of orientations to perform a variety of exercises, including cross-country-skiing-type exercises and rowing-type exercises. The apparatus includes a main frame having said support adapted thereto for supporting the frame on an exercise surface. A track is mounted on the main frame. A pair of foot pedals is slidably mounted on the track means. A reciprocation structure is mechanically associated with the foot pedals for effecting a reciprocative movement of each foot pedal, one relative to the other. At least one pair of movable lever members is mounted on the main frame for movement by the apparatus' user. A foot support is mounted to the main frame for bracing the user's feet when performing various-type exercises.

Abstract: A multipurpose exercise apparatus having the structure and capability of being used in a plurality of orientations to perform a variety of exercises in each orientation, including certain slant-board exercises in at least one orientation of said apparatus. The device including a pair of adjustable lever arms and a seat slideably mounted on a central track. At one end a post is included which forms a slant board attachment. In addition a chest bar is also included for attachment to the levers.

Abstract: A safety switch for electrical or powered exercise equipment is provided. The switch includes a switch body slidingly connected to a bar section of typical exercise equipment. The switch body slides to operate a connected electrical switch. To turn on the equipment, a user depresses a button connected to the switch body and slides the switch on. To turn off, the exerciser need only slide the switch body back to its original position. The switch is adapted and located so that during a fall, the motion of the exerciser's body would typically be in the direction of the off position of the switch.
