Definitions

  • the present invention relates to the sector of exercise machines with counterweights, in which the counterweights consist of a vertical stack of plates positioned one on top of another, which the machine user can select as required, using a selection pin and in proportion to the desired counterweight load.
  • the present invention relates in particular to a remote measuring device, designed to measure several important parameters relating to the mechanical state of the counterweight - such as the static load applied and the intensity of the kinematic speed and displacement parameters of the counterweights during the exercise.
  • devices which can substantially be classed as electromechanical systems, and combined electromechanical and optical systems.
  • the latter include in particular a device - described in document BO2000A000389 in the name of the same Applicant - which, to measure the above-mentioned mechanical parameters, uses a laser unit positioned in a fixed location relative to the machine and equipped with: an emitter part; a laser beam receiver part; and a laser beam reflector part attached to the counterweight plate selector means, the reflector part being opposite and at a given distance from the laser unit emitter part.
  • the length of the flight path covered by the laser beam is normally variable relative to a reference distance predetermined according to a given positional relationship initially predetermined for the various device components.
  • the definition on each occasion of the difference between the actual path of the laser beam and the reference path allows the evaluation of: the number of plates selected, that is to say, the load applied to the counterweight; the displacement of the selector means relative to the reference position; and, by relating this displacement to the time required to complete it, the speed of the counterweight as the exercise is performed.
  • a possible alternative system may be obtained using ultrasound, that is to say, with a device which for a short period of time sends a suitable ultrasonic frequency to a reflector part attached to the selector means. Since the speed of sound in a given means is known, a simple calculation including the interval of time between the pulse sent and the echo returned gives an evaluation of the distance between the device and the reflective surface.
  • the aim of the present invention is, therefore, to overcome such disadvantages using a device which activates the weight stack plate selector means, that is to say, which allows the selector means, with a suitable remote control, to autonomously generate an ultrasonic signal which is then conveniently directed towards the outside.
  • the present invention achieves this result using a detector device for at least one current mechanical state parameter of a mobile counterweight on an exercise machine with counterweights.
  • the counterweight comprises a plurality of weights placed one on top of another, whose number can be selected using a selection pin, which can be attached as required to one of the weights, so as to define a counterweight with a predetermined weight.
  • the device comprises means which generate a signal indicating the instantaneous position of the pin relative to a predetermined reference part; means which detect the signal; the device being characterised in that the generation and detector means are directly opposite one another, separated by a distance which the signal covers only once to minimise the length of its path.
  • the present invention also relates to a measuring method, which conforms to device operation.
  • the above-mentioned device and method allow the important result of making detection of the selection pin position insensitive to the interference around the device, the machine as a whole and/or its component parts.
  • the receiver means are directly opposite the generator means, the first sign on the receiver means of the ultrasonic signal emitted by the generator means, indicating that the signal has covered the shortest flight path, that is to say, that the distance between the generation and detector means has been covered only once, is sufficient to determine the position of the selection pin. Any echoes or signal distortion which follow do not disturb or modify the measurement already taken in any way.
  • the numeral 1 denotes as a whole a device for measuring one or more current mechanical state parameters of a counterweight 2 on an exercise machine 3 with counterweights.
  • the counterweight 2 of the exercise machine 3 opposes the muscular force generated by the user during the exercise and consists of a vertical stack of weights 4, whose number may be selected on each occasion as required by the user, relative to the exercise requirement and using customary selector means, equipped with a selection pin 5 designed to allow the user to set the number of weights 4 to be picked up from the top of the stack and applied to the machine 3 as the resistant force.
  • the counterweight 2 mechanical parameters of practical interest for machine 3 operation may be the most diverse. However, some which deserve special mention are the total weight "P" of the counterweight 2 applied to the machine 3 each time, - Figure 2 - and the movement "s" and instantaneous speed "v" of the vertical stack of weights 4 relative to a suitable, predetermined fixed reference part 19.
  • the device 1 basically comprises:
  • the generation means 14 are preferably designed to include an ultrasonic transmitter 9 able to generate and emit to the fixed apparatus 8 directly opposite, a pulsed ultrasonic signal 18 with appropriate frequency, wavelength and duration "DT" - Figure 4 - following a remote activation command supplied from outside the machine 3.
  • the command which activates the signal 18 generation means 14 is preferably provided by remote control means 17 (generic remote control means of the type with - preferably - or without, wires), operating at a distance from the generation means 14, attached to a fixed apparatus 8 together with the detector means 15 and the processing means 16 - Figure 3.
  • the remote control means 17 which issue the command that switches the mobile element 6 generation means 14 on and off are designed to also switch the fixed apparatus 8 detector means 15 on and off. These means consist of a suitable ultrasonic receiver 10.
  • the fixed apparatus 8 illustrated in Figure 1 has a self-contained structure independent of the exercise machine 3 structure 7. However, this does not restrict the scope of application of the present invention, since, obviously the fixed apparatus 8 may equivalently be attached to and/or built into the exercise machine 3 structure 7.
  • the measuring device 1 may also incorporate a calibration device 12 designed to compensate any variations in the speed of propagation of the signal 18 ultrasound waves due to external interference, caused for example by temperature changes. It also has a monitoring system 13 for the mechanical parameters of the stack of weights 4, detected and/or calculated.
  • the device 1 operates as follows: the remote control means 17 - for example a radio transmitter, or an optical transmitter controlled by the machine control unit which controls its operation - send an activation pulse 20 to the ultrasonic signal 18 generation means 14, fitted on the mobile element 6.
  • the remote control means 17 - for example a radio transmitter, or an optical transmitter controlled by the machine control unit which controls its operation - send an activation pulse 20 to the ultrasonic signal 18 generation means 14, fitted on the mobile element 6.
  • the remote control means 17 enable the detector means 15 to receive the ultrasonic signal 18 and enable the processing means 16 to process the data relevant to the signal.
  • the flight time of the control pulse 20 - however it is issued, whether by radio wave or light pulse - is negligible, since the distance between the generation means 14 and the signal 18 detector means 15 is only covered once, and therefore, with the minimum length of the total distance.
  • the generation means 14 and the detector means 15 of the signal 18 generated by the generation means 14 are activated the moment the pulse 20 is transmitted.
  • the selection pin 5 transmits the ultrasonic signal 18 to the detector means 15.
  • the time which elapses between the pulse 20 being issued by the control means and the ultrasonic signal 18 arriving at the detector means 15 allows the calculation of a distance which is correlated to the position of the selection pin 5 on the stack, that is to say, to the number of weights selected, and that is, the weight "P" selected.
  • the length of the ultrasonic signal 18 path that is to say, the distance between the selection pin 5 and the detector means 15 is detected as often as possible, being reiterated many times in the unit of time at cyclical intervals, for example at least ten times per second. This is done in order to achieve a suitable signal resolution for the measurement or measurements during the exercise with the machine moving.
  • the measuring device 1 therefore allows the expected results to be achieved in a simple, reliable and relatively economical way, without being affected by interference caused by reflection of the ultrasonic waves by any obstacles constituted by the machine 3, its component parts and/or other objects near the machine. These reflections or interference, when the sound emission has been switched off, are exhausted and only reproduced after renewed activation, but always in such a way that they do not affect the precision of the measurement.
  • ultrasonic signals 18 such an embodiment is provided by way of example only.
  • different types of signals 18 may be used, for example signals with a wavelength within the range of frequencies and wavelengths typical of radio waves; or light waves operating both in the visible light spectrum and in the infrared electromagnetic radiation spectrum.
