Definitions

• the invention relates to physical exercising apparatus and, more particularly, to cable-operated exercising apparatus which affords a variety of weight training exercises.
• Cable-operated weight training equipment is well-known in the exercise equipment art.
• such devices comprise a vertically guided, weight-laden carriage which is lifted by a user through an arrangement of pulleys and cables.
• it is desirable to make such equipment versatile for performing many different types of exercises by providing means for exerting exercise forces in many di f ferent directions.
• this typically is provided by upper and lower, and sometimes intermediate pulley positions. See, for e x a m ple , S m all U .S . 4 0 3 , 7 0 3 ; Medart U .S. 931 , 699; M orr is U.S. 2,977,120; and Reach U.S. 676,771.
• the weighted carriage itself has a pulley and is lifted by means of a cable trained around that and other pulleys, a mounting to a traveling pulley system wherein only half the weight on the carriage is required as a pulling force to lift the carriage due to the mechanical advantage of the system. Accordingly, a relatively large stack of weights may be required to provide the requisite amount of resistance to exercise.
• An advantage of this system is that a continous cable may be used extending from the upper pulley through the system to the lower pulley, with appropriate cable stops to anchor each end of the cable, so that virtually no reconfiguration of the equipment is required for changeover from an upper pulling machine to a lower pulling machine.
• Chese m ore U.S. 3,840 ,227; inans U.S. 3,850,431; Szkalak U.S. 4,390,179; and Mazman U.S. 3,905,599 disclose exercise devices wherein the stack of weights may be lifted by any one of a number of mechanisms, thereby affording a variety of exercises. In each of these devices, the weights themselves are lifted by a cable which is attached directly to the weighted carriage (without a traveling pulley), thereby applying the full load to the cable and minimizing the amount of weight required for a full range of exercise loads.
• an object of the invention to provide a cable- operated exercise device which is simple in construction and operation, requires a minimum amount of weight or resistance to achieve desired effort levels, and does not require reconfiguration or reconnection of the working parts of the device to change from one mode of operation to another, or undesirable movement of portions of the device during exercise.
• Another object of the invention is to provide such an exerciser wherein the unused lifting cable will not slacken and possibly foul in the equipment when the carriage is raised by the other lifting means.
• Another object of the invention is to provide such an exerciser wherein the unused lifting cable remains stationary during use of the other lifting means so that any handles or other attachments connected to the cable will not interfere with the user's per for mance of exercises.
• a physical exercising apparatus comprising a liftable carriage, vertically extending carriage guide means for guiding the movement of the carriage, resistance means operatively connected to the carriage downwardly biasing and resisting lifting movement of the carriage, and a plurality of alternately useable lifting means operatively connected to the carriage for lifting the carriage against the resistance means.
• At least one of the lifting means comprises a cable having an inner end operatively connected to the carriage, an outer end to which a lifting force can be applied by a user, and an intermediate portion between the inner and outer ends.
• Upper cable guide means adjacent the top of the carriage guide means guides the cable and defines therebeneath a vertical run of the cable along its intermediate portion.
• Outer cable stop means is provided on the cable for limiting downward movement of the cable along the vertical run.
• Cable tensioning means is connected to the inner end of the cable for tensioning and arresting the vertical run of the cable during lifting and lowering of the carriage by another of the lifting means.
• Carriage engaging means is provided on the inner end of the cable for engaging and lifting the carriage when a lifting force is applied to the outer end of the cable, and allowing the carriage to freely move past the stationary vertical run of the cable when the carriage is lifted by another of the lifting means.
• the lifting means may comprise a pair of cables of the same type, in which case the vertical run of one cable remains stationary and taut during lifting by the other cable, and vice versa.
• Alternate lifting means also may Include, for exa mple, a handle directly connected to the carriage, the cable remaining stationary and taut during lifting of the carriage by the handle.
• the resistance means may comprise a stack of selectable weights, springs or any other suitable means for downwardly biasing the carriage.
• Figure 1 is a perspective view of the apparatus according to the invention.
• Figure 2 is a side elevational view of a portion thereof, with parts- broken away to show certain details
• Figure 3 is a sectional view thereof taken along line 3-3 of Figure 2, with some parts removed for clarity;
• Figure 4 is a detail sec tional view of a portion of the apparatus.
• Figure 5 is a sectional view of the apparatus taken along line 5-5 of Figure 2.
• apparatus comprises a generally vertical structure including a base 10 supporting a pair of parallel vertical carriage guides 12 interconnected at their upper ends by means of a cross-piece 14, and two pairs of vertical weight guides 32, secured by braces 33 to cross-piece 14, which guide two stacks of apertured weights W.
• a carriage 34 having journalled rollers 36, travels vertically along guides 12.
• a clevis 38 on each side of carriage 34 supports an apertured weight rod 40 which extends downwardly through aligned apertures in the stack of weights W.
• a weight selector pin (not shown), the handle 42 of which appears in Figure 1, is inserted beneath a selected number of weights W to couple those weights to the weight rod 40 in a conventional manner known in the art so that lifting of the weight rod will lift the selected number of weights.
• a bench assembly 16 is attached to base 10 and helps to stabil ⁇ ize the vertical structure.
• Bench assembly 16 includes a bench base 18 attached to base 10, a platform 20, a beam 22 supporting bench cushions 24, 26, and an exercise bar 28 attached to cables 30 which are operatively connected through the underside of platform 20 and bench base 18 to the weights W contained In the vertical portion of the apparatus.
