Definitions

  • the present invention relates to the fields of athletic exercise and recreational devices and equipment, and to a device, method and system for attaching, measuring and displaying precise forces applied by the user of such devices. More specifically, the present invention allows the add-on attachment of force-measuring-sensors to moving parts in exercise apparatuses, with no recourse to the dismantling of any mechanisms or parts, in a way which maintains continuously precise measurements.
  • the known devices of the prior art fail to provide a solution for an applied-force sensing-device which can be added on to exercise apparatuses such as bicycle, without dismantling and/or replacing certain mechanisms, for example the bicycle gear system, pedals or the crank arm, or crank spider in a manner that allows precise measuring.
  • Exercise environments often introduce reaction forces such as vibration.
  • sensors must be installed and anchored to firmly grip the measured object/part, for achieving precise measurements over time.
  • installation of applied-force sensing-devices often requires the dismantling of mechanisms and replacing the original parts with specialized parts. These parts are often very expensive and usually require professional person expertise to install and maintain.
  • An applied force measuring arrangement is already known as Strain Gage, used to measure the strain forces applied to a surface or object. For example see Transducer-Class® Strain Gages, part number: S1425 or S120P, made by Full Bridge Patterns, Vishay Micro-Measurements. Strain force measuring requires the anchoring of the sensor to the measured surface for maximizing the direct transferring of forces. Furthermore, continuous pressure is also required, to maintain constant and firm contact between the strain sensor and the measured surface or object.
  • a further object of the invention is to disclose at least one component connected to said control unit which is selected from the group consisting of a sensor of crank angular displacement, a temperature sensor and a pedal cadence sensor.
  • a further object of the invention is to disclose a method of measuring a force applied to a bicyclical pedal by a rider.
  • the aforesaid method comprises the steps of: (a) providing a device for measuring a force applied to a bicyclical pedal by a rider; said device is attachable to a pedal crank arm; said device comprises (i) attaching means quickly embracing and detaching from said crank arm; (ii) a spring- loaded leaf; (iii) at least one strain sensor adapted to measure a strain of said spring-loaded leaf, (iv) a control unit; (b) attaching said device to said crank arm; (c) applying a turning torque to said crank arm by said rider; (d) elastically deforming said crank arm by said turning torque; (e) measuring said deformation by means of said strain sensor.
  • a further object of the invention is to disclose the step of measuring said deformation comprising measuring bending deformation of said crank.
  • FIG. 2 presents front, rear, top and cross-sectional views of the device installed on the inner side of a bicycle crank arm;
  • FIGS. 3a and 3b illustrate a perspective view of the device installable onto a bicycle crank arm
  • FIG. 4a illustrates the device, installed on a bicycle crank arm attached by a pedal
  • Fig. 4b illustrates a spring-loaded leaf provided with a strain gage
  • FIG. 4c illustrates the spring-loaded leaf glued to a bicycle crank arm
  • FIGS 5a and 5b present views of the device installable onto a bicycle crank attached by a pedal
  • FIG. 6 is an exploded view of the device, installed on a bicycle pedal
  • the claimed device of the present invention is designed for attaching to standard bicyclical articles and no improvement or modification of the bicyclical articles is needed.
  • an applied-force sensing device, method and system for people who take interest in their performance during athletic activity which device and/or method and/or system may be described in view of Figs. 1 - 7.
  • the device may be shaped as a case hosting electronic components (2) made of resilient material such as Metal or plastic shell.
  • the device may include at least one applied-force sensor such as a strain-gage (5), cased in the shell (2) and provided with a spring loaded leaf (4) for measuring the force applied to an exercise object.
  • a spring-loaded 'leaf (4) is firmly connected to a measured object. Accordingly, the spring-loaded 'leaf (4) may indicate the strain force applied to the object/part/crank arm/pedal (100), to be measured by the strain-sensor (5).
  • the spring- loaded leaf 110 provided with a strain gage 120 (see an enlarged view in Fig 4b) is glued to the pedal crank 100.
  • the leaves 110 with strain gages 120 can be attached in any locations indicated in Fig. 4c. Each sensor should be calibrated according to its location on the pedal crank.
  • Control unit (not shown) can disposed in any convenient location.
  • the attachment of the device may be done on different positions on the exercise device/object, for example, on either side of the crank arm of a bicycle (see fig.lA and fig. IB).
  • the above mentioned embodiment is configured for measuring elastic bending deformation of the crank arm.
  • the device may include all or some of the following components (see fig.7): strain sensors (200); electronic sensor amplifier (201); pedal cadence sensor (202); temperature sensor (204); crank arm angular displacement sensor (205); A/D converter (206); a transmitting device (207); a microprocessor (208) and wireless communication means 209.
  • the users may operate the system by pressing the calibration button arrangement (101) to calibrate the applied force measurement sensor before each exercise activity.
  • the calibration process may be done automatically by calculation processes in the microprocessor (208), or by calculation processes in the external wireless device (203).
  • this invention provides a means structured to allow easy add-on attachment of the sensing device to the measured exercise object/part, to provide constant tightened contact between the sensing device and the measured object even under constant vibrations and to directly process and transmit the measured data to an external device, thus improving the integration and ease of use of exercise enhancing applications.

Abstract

L'invention concerne un dispositif permettant de mesurer une force appliquée à une pédale bicyclique par un cycliste pouvant être fixé à un article bicyclique standard. Le dispositif comprend (a) un moyen de fixation adapté pour entourer rapidement ladite manivelle et s'en détacher ; (b) une lame montée sur ressort fixée à la manivelle ; (c) au moins une jauge de contrainte adaptée pour mesurer une déformation de la lame montée sur ressort ; et (d) une unité de commande. La lame montée du ressort est collée à la manivelle.
