Abstract: An inertia controlled loading system for an exercise apparatus or the like. The system includes a rotatable member mounted on a frame together with a mechanism for rotating the rotatable member through a drive pulley operatively associated with the rotating mechanism and a driven pulley operatively associated with the rotatable member. It also includes an endless belt member drivingly interconnecting the pulleys such that the belt member imparts rotation of the rotating mechanism to the rotatable member through the drive and driven pulleys which occurs because of the fact that the belt member has a surface in driving engagement with the pulleys. The system further includes a non-rotating frictional surface member in engagement with the belt member intermediate the drive and driven pulleys. With this construction, the inertia controlled loading system is suitable for an exercise apparatus or the like.

Abstract: A drive system for an exercise apparatus or the like. The system includes a rotatable member mounted on a frame together with a mechanism for rotating the rotatable member through a drive pulley operatively associated with the rotating mechanism and a driven pulley operatively associated with the rotatable member. It also includes an endless belt member drivingly interconnecting the pulleys such that the belt member imparts rotation of the rotating mechanism to the rotatable member through the drive and driven pulleys which occurs because of the fact that an inner surface of the belt member is in driving engagement with the pulleys. The system further includes a component frictionally engaging an outer surface of the belt member in the area in which the inner surface of the belt member is in driving engagement with the drive pulley to impart a resistance to rotation of the rotating mechanism. With this construction, the drive system is suitable for an exercise apparatus or the like.

Abstract: A coilable member, such as a measuring tape, is replaceably supported within a device for extension and recoiling. A separable casing defines an aperture through which a coilable member can be extracted and retracted, and has an interior portion defining a bearing surface for supporting for rotation a first reel adapted to retain a spring secured to the reel. The first reel rotatably supports a second reel adapted to support the coilable member secured thereto and extending through the aperture defined by the casing. The second reel is supported in the casing by the first reel for relative axial movement with respect to the first reel. Braking means, which can include an annular member having teeth which engage at least one of the reels, rotates therewith in the casing substantially freely in one direction, while causing retardation of the rotation of the reel in the opposite direction through frictional engagement with the side of the casing.

Abstract: A mixer for mixing flowable material in a container rotates the material continuously in one direction about a first axis and simultaneously about a second axis which is non-perpendicular to the first axis, the first axis rotating about the second axis. The mixer has means for supporting the container and for rotating the container simultaneously about the two axes. Desirable top to bottom circulation of material within the container is attained by the mixer of the present invention, while the apparatus is simplified and provides economies due to its lower speed and unidirectional, continuous rotational operation.

Abstract: A reclining chair adapted to be positioned in close adjacency to a wall, the chair having a frame and a body supporting unit which is movable relative to the frame between an upright sitting position and a variety of reclining positions. The frame is supported on ground engaging rollers and on rocker feet, the latter being connected by linkage arrangements to the body support unit. When the occupant moves the body supporting unit to reclining position both the chair frame and body supporting unit are caused to be moved away from the wall so that no part of the chair is in physical contact with the wall. Substantially 40% of the movement away from or toward the wall is effected by the body supporting unit and substantially 60% of the movement is effected by the frame. Upon movement to upright position the chair frame and body supporting unit return to the original position in close adjacency to the wall.
