Abstract: An exercise arm assembly for mounting on an exercise machine frame has a main arm, a swing arm, and a handle. The main arm has a first end for pivoting on a frame of the machine to pivot about a first pivot axis. The swing arm has a first end pivoted to the second end of the main arm for pivoting about a second pivot axis. The handle is pivoted to the swing arm for pivoting about a third pivot axis, with each pivot axis being perpendicular to the other two pivot axes to form a perpendicular, tri-pivot arm system.

Abstract: A composite motion exercise machine has a main frame, a user support, an exercise arm, a movable wedge, a connecting device, and a load. The user support and exercise arm are pivotally linked directly or indirectly to the main frame, and the movable wedge has first and second travel members in moving engagement with rails on the main frame and user support, respectively. The connecting device links the movable wedge to the exercise arm, such that movement of the exercise arm moves the wedge along the rails to lift the user support in an arcuate path away from the main frame.

Abstract: A composite motion exercise machine has a main frame device, a user support device pivotally linked to the main frame, an exercise arm device pivotally linked to the main frame device, a slide rail mounted on a first one of said devices, and a traveling member engaging the slide rail for movement along the rail. A first connecting link has a first end connected to the traveling member, and a second end linked to a fixed position on a second one of said devices. A further connection device links the traveling member to the exercise arm device, such that movement of the exercise arm is transferred to the user support to lift the support and user.

Abstract: A foldable exercise bench is movable on a frame between a retracted, generally upright storage position and at least one deployed position for supporting a person during exercise. A support foot located adjacent one end of the bench is pivotally mounted for rotation between a first, storage position extending generally alongside the bench when the bench is in the storage position, and a second, support position in which the support foot extends forwardly at an angle to the bench and engages the floor to support the bench in the deployed position. A four-bar connecting linkage between the bench and frame automatically pivots the support foot from the second position to the first, storage position and locks it in the storage position when the bench is folded into the storage position.

Abstract: An exercise apparatus has a support frame and an exercise arm assembly pivotally linked to the support frame for swinging movement in at least one fixed arc about a first pivot axis, the exercise arm assembly including at least one rigid, elongate exercise arm. A flexible handle assembly is secured to the exercise arm, the handle assembly having a hand grip portion for gripping by a user, and a flexible connecting portion securing the hand grip portion to the exercise arm to permit a variety of different upper body exercises to be performed by moving the hand grip portion in selected different paths as permitted by the flexible connecting portion.

A flexible handle assembly is secured to the exercise arm, the handle assembly having a hand grip for gripping by a user, and a flexible line secured to the hand grip at one end and adjustably secured to the exercise arm to vary the extension of the line from the exercise arm. Upper body exercises are performed by moving the hand grip portion in different paths as permitted by the flexible line.

Abstract: An adjustment apparatus for adjusting the position of a member on an exercise machine has an inner tube with a series of spaced pinning holes and an outer tube telescopically engaged over the inner tube and having a locator hole for alignment with a selected pinning hole. A lever has a pinning section pivotally mounted on the outer tube to extend across the locator hole, and a hand engaging section extending at an angle to the pinning section. The pinning section is pivotable between an operative position in which a pinning button projects through the locator hole and an aligned pinning hole in the inner tube to secure the tubes together, and a retracted position in which the pinning button is spaced from the locator hole. A handle is mounted on the outer tube to extend in the same general direction as the hand-engaging section such that a user gripping the handle can engage the hand-engaging section and urge it towards the handle to pivot the pinning section into the retracted position.

Abstract: An exercise arm apparatus has a stationary frame member, a first pivoting arm pivoted to the frame member at a location intermediate its ends for rotation about a first pivot axis, a second pivoting arm pivotally connected to the frame member for rotation about a second pivot axis spaced from the first pivot axis, and a connecting link pivotally connected to the first arm and second arm to form a four-bar linkage. The first arm is an exercise arm with handles at one end for gripping by a user, and the connecting link is of sufficient weight to form a counter-weight to counter-balance the first exercise arm into a rest position corresponding to a start position for an exercise movement. In one example the connecting link is a solid, elongate bar of heavy metal or equivalent material.

Abstract: A stackable weight plate for an exercise machine weight stack has a front edge, a rear edge, opposite side edges, an upper face, a lower face, and an aperture extending between the upper and lower face for receiving a weight stack selector stem. The front and rear edges having a matching arcuate curvature with one edge being convex and the other edge being concave, and the side edges are tapered at an angle from the front edge to the rear edge.

Abstract: An exercise apparatus has a support frame and a seat mounted on the support frame having a forward end. A leg exercise arm has a first end pivoted to the support frame adjacent the forward end of the seat, and a second end. The arm has a continuous curve extending along at least a major portion of its length and bending through an arc of at least 180 degrees. In its rest position, the arm first projects forwards from the pivot and then bends back rearwards. A cable links the arm to an exercise resistance, and a leg engaging assembly is mattached to the arm for engagement by the legs of a user in performing exercises.
