    • A cabinet has a tread base rotatably connected to be oriented in an exercise position extending outwardly and in a stored position extending inwardly secured within the enclosure of the cabinet. The underside of the tread base may be configured to provide a suitable aesthetic exterior surface. A latching arrangement provided to secure the tread base within the enclosure in the second or stored position. Elevation structure and motor structure are provided to elevate the tread base when in the first position and to power the endless belt of the tread base when in the first position. The elevation structure may be operated to vary the inclination of the tread base when in the first position. The underside of the tread base has a decorative panel and functions as a door for the cabinet. The elevation structure may include an electrically driven rack and pinion as well as a gas cylinder system.

    • An ergometer (28) is employed on an exercise cycle (10) having a flywheel (20) rotated by pedals (16). A selectively tensionable endless belt (26) extends around the perimeter of flywheel (20) and a separate strap (160) is attached to the endless belt (26) to extend tangentially from the flywheel (20). The opposite end of strap (160) is connected to one end of an indicator plate (162) with the other end of the indicator plate attached to one end of an extension spring (164). The extension spring (164) imparts a tensile load on strap (160) equal to the opposing tensile load on the strap (160) imposed by the frictional force acting between endless belt (26) and the flywheel (20). This force level is sensed by the movement of the indicator plate (162) which coincides with the extension of spring (164), which plate movement corresponds to the workout level being achieved. The workout level in terms of calories per minute is displayed by indicia disposed on the upper side of the indicator plate (162) visible through a window (30) formed in the frame structure (40) of the exercise cycle (10).
    • 在具有由踏板(16)旋转的飞轮(20)的运动周期(10)上采用测力计(28)。 可选择张紧的环形带(26)围绕飞轮(20)的周边延伸,并且分离的带(160)附接到环形带(26)以从飞轮(20)切向延伸。 带(160)的相对端连接到指示板(162)的一端,指示板的另一端连接到延伸弹簧(164)的一端。 拉伸弹簧(164)将带状物(160)上的拉伸载荷赋予等于通过作用在环形带(26)和飞轮(20)之间的摩擦力所施加的带(160)上的相对的拉伸载荷。 通过与弹簧(164)的延伸重合的指示板(162)的运动来感测该力水平,该板移动对应于所实现的锻炼水平。 通过设置在指示板(162)的上侧的标记,通过形成在锻炼周期(10)的框架结构(40)中的窗口(30)可见的标记来显示锻炼水平。
