Definitions

  • This patent application concerns a device for body building machines that generates an adjustable resisting force on the same.
  • this power unit consists of a series of metal prismatic blocks, generally called “weights”, housed and sliding along two upright bars having a circular cross-section, that traverse the entire pile of weights at two symmetrically opposite points with respect to the barycentre of each weight.
  • the weight selecting device generally consists of a vertical bar subject to the direct or indirect lifting force applied by the athlete, which is fitted into the hole at the centre of each weight; said bar being characterised by a series of transverse through holes having equidistant horizontal axes in which the plug for selecting the weight is fitted.
  • the body builder may select the number of weights to lift, according to physical effort he wants to exert, simply by sliding the plug into one of the holes of the above vertical bars; naturally the lower the hole selected, the greater will be the number of weights to be lifted.
  • the power unit consists of one or more pneumatic jacks on whose piston the muscular force of the athlete is unloaded, generally by means of lever mechanisms; in this type of machine the resistance created by the piston may be adjusted by varying the air pressure in the jack.
  • the purpose of this invention is to design a new device for generating an adjustable resisting force for body building machines.
  • the device according to the invention consists of a lever on which a sliding mass is fitted, whose weight generates, with respect to the pivoting point of the lever, a moment of resistance whose force is directly proportional to the distance between the pivot and the barycentre of the mass.
  • One of the two ends of said lever being fitted with attachments for the mechanical devices (such as cables, chains or levers) generally used to transmit the muscular force that the athlete exerts on the handles or foot board of the machine, to the power unit.
  • the mechanical devices such as cables, chains or levers
  • the device according to the invention is fundamentally characterised by a lever, having a fixed driving force arm (namely the force exerted by the athlete) while the resisting force arm (namely that corresponding to the weight of the sliding mass) varies so that the athlete is required to exert an effort proportional to the arm of the resisting force.
  • - fig. 1 is an axonometric view of the device according to the invention in its preferred embodiment, characterised by the use of an actuator to activate the sliding action of the above mass.
  • the device according to the invention is characterised by a lever (1) consisting of a parallel pair of longitudinal bars (1a) joined together by means of two transverse bridges (1b) positioned at the ends of the bars (1a); a fork (1c) being provided above and at the centre of one of the bridges (1b) in order to hook the mechanical means, which in this case, is a chain (2), used to transmit the muscular force that the athlete exerts on the handles or foot board of the machine, to the power unit.
  • a lever (1) consisting of a parallel pair of longitudinal bars (1a) joined together by means of two transverse bridges (1b) positioned at the ends of the bars (1a); a fork (1c) being provided above and at the centre of one of the bridges (1b) in order to hook the mechanical means, which in this case, is a chain (2), used to transmit the muscular force that the athlete exerts on the handles or foot board of the machine, to the power unit.
  • Said lever (1) is pivoted to the supporting frame (3) of the machine by means of two horizontal coaxial pins (4), projecting externally from the longitudinal bars (1a), at the bottom whereof two circular supporting and guiding bars (5) are fitted for a cylindrical drum (6) having two opposing supporting couplings (6a) fitted and sliding on the above bars (5).
  • the drum (6) slides automatically by means of an actuator fixed externally to a fixing plate (8) over the back of the pair of bars (1a).
  • the actuator consists of an electric motor (7) having a reduction gear that rotates a threaded shaft (9) fitted in the drum (6) with the same being coupled helicoidally so that the rotation of the shaft (9) translates the drum (6) along the respective support and guide bars (5).
  • the drum (6) can quite obviously be motorised with any other suitable means, without absconding from the inventive concept; the drum (6) could, for example, be joined to the piston of a pneumatic jack, flanged externally to the plate (8) or the drum (6), could be joined to a geared rack having a pinion rotated by an electrical motor.
  • the drum (6) may also be made to slide manually; in this case, means for stopping the drum (6) along the bars (5), should be provided.
  • a calibrated line marked with the number (10) is shown in fig. 1, having a scale that shows the power that the athlete must exert to move lever (1) according to the position of the sliding drum (6) along the bars (5).
  • the value of this power may be visualised on a monitor by means of a conventional electronic device involving the use of an optical detector (11) mounted on the drum (6) that reads fixed reference marks (11a) along the bars (1a) of the lever (1).
