An exercising machine for especially training the muscles of the leg includes a base on which a pair of support tables is rotatably carried, one for each foot, a vertical standard on the base adapted to provide fixed hand grips for a standing user or a seat for a sitting user, and a pair of resistance devices preferably formed by a selectable number of weights. Each resistance device is respectively connected by a cable and pulley system to one of the support tables to provide a variable reactive force as the associated support table is moved out of a neutral position. The seat and hand grips can be set at a selected height, the hand grips can be set at three positions in one horizontal plane, and the foot-supporting portion of each support table can be placed in a selected angular position by which the neutral or starting position is picked. The machine can be used close to a wall.
A physical exercising machine according to the invention includes a pair of rotatably supported tables, each adapted to support a single human foot, the tables being coupled with a pair of resistance devices, providing a reactive rotary force of automatically varying intensity in response to support table rotation, there being stationary transmitting means by which a reactive force is transmitted to the human body. The transmitting means are adjustable in order to adapt the exercising machine to a given size of person and to a given type of exercise, one such means being in the form of hand grips and another being in the form of a seat. The resistance means is in the form of weights acting through a cable on said support tables.
A physical exercising machine according to the invention is shown in FIG. 1, generally indicated by the numeral 15. The machine 15 includes a base 16 to which is secured a vertical standard 17, and a pair of hollow vertical columns 18, 19, the upper ends of the standard 17 and columns 18, 19 being joined together by a primarily horizontal strap 20. The vertical standard 17 supports a transmitting means 21, here comprising a post 22 and a pair of hand grips 23. A manually removable or insertible pin 24 fixes the height of the post 22 at a selected height, there being a suitable number of holes in the post 22 which are capable of receiving the pin 24 in the manner illustrated in FIG. 2. The post 22 has additional holes 25, that extend through the post so that the post can be placed a quarter of a turn from the position shown in FIG. 1 and there locked in order to adjust the starting position of the hands for a given exercise. Thus, the holes lie substantially in one horizontal plane, and multiple sets of such holes enable the setting of the height of the hand grips to compensate for different heights of users.
As best seen in FIG. 5, the base portion 33 is apertured and receives and supports a bearing insert 40, an inner cylindrical surface of which is normally lubricated with oil, there being a cap 41 secured to the lower end of the bearing insert 40 to retain it in place and to prevent any leakage of oil. The presence of the end cap or oil seal or retainer 41 also necessitates the use of a number of pads 42 at the corners of the base 16. The lower table part 32 has a hollow cylindrical bearing 43 secured thereto which is received in and guided by the bearing insert 40. An annular bearing 44 surrounds the upper end of the tubular bearing 43 and provides thrust reaction or support between flanges on the bearing insert and on the tubular bearing. The upper table part 31 has a guide pin 47 secured thereto which functions as a pilot and enables the upper table part 31 to be rotated with respect to the lower table part 32 when it is lifted as shown in FIG. 5 so that a locating pin 45 is retracted from one of a series of holes 46. With this arrangement, the upper table part can be raised slightly, rotated to a selected new position, and the locating pin be reengaged with a different one of the holes 46, there being a continuous series of such holes as shown in FIG. 7. An identifying indicia is placed on the upper surface of the lower part 32 adjacent to each hole 46, diametrically opposite holes 46 having the same indicia. The upper table part 31 is covered with a non-skid material 48, and in addition, has a U-shaped foot guide 49 secured thereto, the same being lined by a strip of cushioning material 50. The U-shaped foot guide is specifically shaped to accept primarily soft rubber soled sports or exercise shoes of the widest wariety of lengths and widths, and is shaped so that only a slight lateral rotary motion of the foot, at the beginning of an exercise movement, will cause the foot to lock against either inside face of the U-shaped foot guide. The U-shaped guides 49 are a preferred feature by which each support table is adapted to support a single human foot, a circumstance that applies to the exercises described below. Should a user wish to use the machine in a less preferred mode, the U-shaped guide can be readily detached as a set of mounting screws 51 can be manually removed. The upper table 31 has a viewing window or slot 52 through which one of the indicia 53 on the lower table part may be viewed, it being the one associated with the hole in which the location pin 45 is disposed. The upper part 31 also has a set of indicia 54, similar identification being provided at similar distances at either side of the viewing slot or window 52. The indicia 54 cooperate with suitable indicia such as 55 (FIG. 2) for indicating to the user how far a particular support table has been moved from a neutral or starting position, either clockwise or counterclockwise. In each of the views, the U-shaped guides 49 are directed to open toward the vertical standard 17 for use with the transmitting means 21. When the transmitting means 26 are employed, then the upper parts 31 of the support tables are raised and turned 180° from as shown in FIG. 5 so that the U-shaped guides are directed away from or open away from the vertical standard 17. Thus in any event, the transmitting means is always at a common lateral side to the support tables 29, 30. Thus the starting or neutral point for the U-shaped guides is adjustable for 360° in relatively small increments, namely 10° increments in this illustrated embodiment.
