Definitions

  • the present invention relates to a drive device for golfers which allows you to measure and analyze the strike of a golf ball, by its distance between the shooting point and the point ball drop.
  • This training device allows golfers to train in a small space. Hitting the golf ball suspended from said device, golfers see the distance the golf ball would have normally traveled in normal conditions of a golf course.
  • the golfer also sees the shooting angle of his ball or, depending on the different embodiments, the distance existing between the point of fall of the ball and the perpendicular, from the initial trajectory, passing through the drop point.
  • Document FR-A-2,649,901 relates to a device allowing golfers to swing swings in small spaces. he consists of a standard golf ball attached to one end the cord, a base secured to a carpet fitted with a tee. The other end of the cord goes through the guide, wraps around the pulley. At the start, the spring is relaxed. The stopper is in support on the guide. After the swing, the ball stops, the spring, stretched, pulls the cord. The rollers block the pulley. The pedal controls the rebound of the spring. The pebbles driven by the pulley slows the return movement. The device according to the invention opposes the violent return and dangerous ball.
  • Document WO-A-91/01166 proposes a device allowing an individual to train alone or with a partner to type golf shots which includes a golf ball attached by a non-elastic cord to a coil of cord and an elastic segment attaching the rope to an anchor point of the device to facilitate the return of the ball.
  • the length of the rope can be determined by the golfer and wound up using the reel so put it away after use.
  • the document FR-A-2,598,924 has the particularity of a device for golfers, more commonly known as “driving range” golf course ", which is characterized in that it consists of a gallows whose horizontal branch carries a coil or the like, for supporting and unwinding a wire at the free end of which a golf ball is attached, the wire can be unwound from the top down to ground level and the coil can be blocked in rotation.
  • the goal is to allow golfers to practice their gestures, but without no possibility of analyzing the blow which results from it.
  • WO-A-93/08881 relates to a method and an apparatus used to measure the length of a golf drive, the method of measuring the initial speed of a golf ball attached to a rotary axis by means of a string.
  • the axis carries a slotted disc, which cooperates with a receiver unit and optical sensor to determine the angular speed of the axis.
  • the optical unit output signal serves as an input signal for an electrical device that will calculate the distance that the bullet would have traveled if it had not been tied. The calculated distance is displayed on a display device at liquid crystals.
  • the value of the length of the blow is not reliable since, due to the structure of the device, a small inclination of the golf ball suspension cable, moved in rotation, will cause increased friction and a loss of kinetic energy of the ball.
  • This is due to the fact that when the bale is rotated on a fixed axis at shoulders, it cannot describe a regular rotation, since the twine on the fixed axis will go from a shoulder to each other on every U-turn, which will slow the speed of the ball and cannot give even a rough idea of the strike of it. The distance displayed will therefore be distorted with respect to at the true distance.
  • the document US-A-3,472,075 relates to a system of golf simulation, in which the results associated with a stroke golf courses are indicated by a mobile display.
  • Bullets counterweights are attached to the ends of a tube which is carried by a horizontal shaft mounted movable in rotation.
  • a structure simulating the ground is located below the horizontal tree, of so that the balls continually pass over it.
  • the tree horizontal can also be moved axially, just like this is the case in rotation, and each movement is applied to a structure forming a screen.
  • a hint of reading or a marker is mobile on the screen, to allow the representation, on a reduced scale, of the trajectory of the ball.
  • the rotating movement poses no problem
  • the axial movement of the horizontal shaft is made by moving the tube and balls, located at the end of said tube, this displacement being carried out in "a single block".
  • the tube will therefore undergo bending forces to allow the shaft to be moved axially.
  • the structure of the simulation system is not adapted to receive such forces, which will increase friction and distort the angle and length values of shoot.
  • the object of the present invention is to resolve all of the disadvantages of the state of the art, by proposing a training device for golfers intended to measure and analyze the strike of a ball.
  • Said device is of the type consisting of a gallows whose free end of the branch horizontal is fitted with a cable suspended in a rotatable way and at the lower end of which the ball is fixed and suspended golf at ground level, when the device is at rest, the horizontal branch contains a main axis movable in rotation and in translation according to the distance and the shooting angle, the means link ensuring the connection between the upper end of the cable and main axis.
  • the device is characterized by the causes said connecting means to be a cam cooperating with the axis main mobile in rotation and translation so that any displacement of said connecting means in its plane, during the setting in rotation of the assembly, causes a displacement in translation of said main axis movable in rotation and in translation, transmits to said movable main axis, so proportional, the speed of rotation of the ball around said axis and its firing angle, and is characterized by the fact that one or several sensors transmit data to means which analyze the axis rotation speed to determine the distance of the shot and the transverse displacement of said movable axis to determine the distance between the drop point of the ball and the reference trajectory.
  • the first axis is placed above of the second axis.
  • the first axis is placed below the second axis.
  • the main movable axis in rotation and in translation is coaxially and partially enclosed in a hollow axis, and the connecting means and the end of the movable axis, which cooperates with said connecting means, are positioned inside a hollow nut, the hollow axis and the hollow nut forming a single mobile casing in rotation.
  • the second axis is integral with the hollow nut.
  • the main axis is partially enclosed in a coil and acts as a metal core, and the sensor (s) are sensitive to variations in magnetic fields due to displacement of the main axis inside the coil.
  • the main axis comprises, at the level of or optical sensors, on the one hand, a painting area reflecting light from a light source, and on the other hand, a paint area absorbing said light.
  • the interface between the two painting zones is then formed by an ellipse corresponding to a cross section with respect to the axis longitudinal of the moving axis.
  • the means of analyzing the data transmitted by the sensors are formed by at least one trigger, at least one sequencer, at least one integrator, and at least one comparator, which cooperate to display part of the distance on a screen of the shooting and on the other hand of the distance between the point of fall and the reference trajectory.
  • the device includes a base.
  • Figure 1 shows a general perspective view of a embodiment according to the invention where the device comprises a base allowing the golfer to position his feet on said base, which at the same time stabilizes the device on the ground.
  • Figure 2 shows a perspective view of another mode of achievement.
  • Figure 3 shows a longitudinal section of the branch upper horizontal of the gallows forming the frame of the drive device, in which the connecting piece is at rest or is rotated without deviation angular, according to another embodiment.
  • FIG. 4 represents a section along N-N in FIG. 3.
  • FIG. 5 represents a view identical to FIG. 3, but in which the connecting piece is animated by a movement of rotation with angular deviation to the right or to the left.
  • Figure 6 shows a longitudinal section of the branch upper horizontal of the gallows forming the frame of the drive device, according to another embodiment, in which the connecting piece is at rest or is animated by a rotational movement without angular deviation.
  • FIG. 7 represents a section along M-M of FIG. 6.
  • FIG. 8 represents a view identical to FIG. 6, but in which the connecting piece is animated by a movement of rotation with angular deviation to the right or to the left.
  • Figure 9 shows a developed end of the axis main bearing a painted helical band; in this figure, a full turn is delimited by the two dotted lines vertical.
  • FIG. 10 represents the information recorded at using sensors according to the angle of inclination taken by the part link, cable and golf ball.
  • Figure 11 shows the principle of the circuits used for bullet angle and distance calculations that she would have crossed if she had been free.
  • Figure 12 shows the voltage variations at the output of the various components forming the circuits used for the calculations.
  • the present invention relates to a drive device 1 intended for use by golfers 45 who wish to measure and analyze the strike of their shots.
  • This strike is made on a ball 2 which is fixed and suspended at the end of a cable 5, itself suspended so rotatable relative to a horizontal branch 4 of a bracket 3.
  • This bracket 3 forms, with a base 13, the whole of the structure of said device 1. This is clearly seen in the figure 1.
  • connecting means 6 or 16 which ensures the connection between the upper end of the cable 5 and an axis main mobile in rotation and in translation 7 or 17, present at the horizontal branch 4 of the bracket 3.
  • the essence of the invention resides in the fact that the means 6 or 16 has the possibility of transmitting to the axis main mobile 7 or 17, proportionally, the speed of rotation of the ball 2 around said axis 7 or 17, as well as the firing angle, i.e. the angle between the perpendicular plane to the moving axis and the plane of rotation of the ball.
  • a sensor 8 will allow transmit the data to means which will be described subsequently, these means being able to analyze on the one hand the speed of rotation of the movable main axis 7 or 17 for determine the distance of the shot, and on the other hand the displacement transverse of said movable axis 7 or 17 to determine the angle of firing and, by extension, the distance d between the point of fall and the perpendicular, coming from the initial trajectory 46, passing by the drop point.
  • the trajectory 46 is symbolized on the ground, formed by the base 13, by a straight line or initial trajectory 46. This distance d is easily calculated by the means of analysis of the data transmitted, by a simple trigonometric calculation, since d is related to the side opposite of a right triangle, whose angle we know and the hypotenuse which is equal to the shooting distance.
  • This connecting means 6 or 16 is formed by a cam 6 or 16.
  • This connecting means 6 or 16 cooperates with the main axis movable in rotation and in translation 7 or 17, via firstly of a first articulation axis 9 or 19, which is integral and perpendicular to said main axis 7 or 17, around from which the connecting means 9 or 19 can pivot in a formed plane by the main axis 7 or 17 and by the suspended cable 5, then, via a second articulation axis 10 or 20 parallel to the first axis 9 or 19; this second axis 10 or 20 is mobile in rotation, like said first axis 9 or 19, but fixed in translation, which is not the case for axis 9 or 19.
  • the first axis 9 is mobile in rotation as well as in translation. This one 9 is placed below the second axis 10.
  • the first axis 19 is placed above the second axis 20.
  • This first axis 19 is mobile in rotation and in translation, while the second axis 20 is movable in rotation only.
  • axes 10 and 20 which are fixed in translation, are secured to a hollow nut 12 or 22. This is itself secured to a hollow axis 11 or 21.
  • This hollow axis 11 or 21 is coaxial and partially encloses the main axis movable in rotation and in translation 7 or 17.
  • the main movable axis 7 or 17 exceeds, by its two ends, the hollow axis 11 or 21.
  • One of its ends cooperates with the connecting means 6 or 16 and is positioned inside the hollow nut 12 or 22.
  • the other end has the function of allowing the measurement on the one hand of the rotation of said movable axis 7 or 17 and on the other hand of its translation; it will therefore cooperate with the sensor 8.
  • the assembly formed by the hollow axis 11 or 21 and the hollow nut 12 or 22 forms a single mobile casing in rotation.
  • the second axis 10 or 20 will therefore be secured to the nut digs 12 or 22 and allows the rotation of the other axis 9 or 19 in the plane formed by the movable axis 7 or 17 and the cable 5, and thus, the displacement in translation of the main axis 7 or 17.
  • the connecting means 6 or 16 therefore has the function of a lever arm.
  • the free end of the main axis 7 or 17, which allows to analyze the length and the angle of shot, is placed in the field of action of a sensor 8, which according to a mode of realization may be sensitive to variations in magnetic field for example, using the movable axis 7 or 17 as a movable soft iron core inside a coil in which current is injected, which will tend to increase or decrease magnetic fields depending on the amount of iron soft present inside the coil.
  • the main axis 7 or 17 comprises, at the level of the sensor optics 8, on the one hand a painting area reflecting the light 14 coming from a light source, and on the other hand a paint area absorbing said light 15.
  • This interface 18 is formed by an ellipse corresponding to a bias cut from the longitudinal axis of the movable axis 7 or 17. This is clearly seen in Figures 3 and 6.
  • the device is thus thus made only when the cam 6 or 16 oscillates around its fixed axis in translation 10 or 20, the axis main mobile 7 or 17 in translation according to F3 or F4 or else F7 or F8 and in rotation, according to F9, moves longitudinally at inside the hollow axis 11 or 21 and its displacement is then proportional to the oscillation angle according to F1 or F2 or F5 or F6 of said cam 6 or 16.
  • optical sensor or the photoelectric cell 8 is placed opposite the part of the main axis 7 or 17 which carries the paint zones 14 and 15 and is substantially centered with respect to these 14 and 15.
  • an emitting diode and a cell 8 capable of capture the light received and reflected by zones 14 and 15 located next to the diode and cell 8, will allow determine the durations and the number of passages at the level of each zone of reflective 14 or absorbent 15 paint.
  • the photocell 8 goes follow line A of figures 9 and 10.
  • the passage time of the black area in front of said photoelectric will be equal to the time of passage of the reflective zone.
  • the cell will deliver an alternating signal in the form of a report slot cyclic substantially equal to one.
  • cell 8 will follow the sinusoidal line B which crosses the boundary between the black and reflective areas in half points. In this case, the rising and falling sides are will shift and the duty cycle will no longer be the same. he will be representative of the inclination of the plane of rotation of the ball.
  • the signal from the photoelectric cell 8 is sent to a shaping circuit, of trigger type 23 and whose output signal 34 is sent on the one hand to a sequencer 24 and on the other hand to an integrator 25.
  • the sequencer 24 generates control signals for the different electronics circuits. These signals come out on outputs 38, 39, 40 and 44.
  • An integrator 26 receives a reference voltage 31. It is triggered at a time TO by the output 38 of the sequencer 24 during the first rising edge of signal 34, from trigger 23. It integrates the reference voltage up to a time T1 triggered by the next rising edge of signal 34, therefore for the duration of an entire period of the input signal, i.e. during a full turn of ball 2, hereinafter called the reference turn.
  • the output 36 of this integrator will vary all the more quickly that its input voltage 35 will be large and therefore that the duration of the reference lap will have been long.
  • This output is sent to a comparator 30 which compares it to a reference voltage. When this voltage reaches the reference voltage, at a time T2, the comparator 30 sends a control signal 37 to sequencer 24.
  • the interval T2-T1 is shorter the more the input voltage of the integrator 27 is large and therefore that the reference turn has been long. This time is therefore proportional to the speed of the bullet when fired.
  • the sequencer 24 also controls, via its output 40, two successive integrators 28 and 29, during the interval T2-T1.
  • the integrator 28 receives the reference voltage 31 which it integrates therefore during the time interval T2-T1. Its output voltage, at time T2, is proportional to this interval T2-T1.
  • the integrator 29 integrates the output voltage 41 of the integrator 28 during the same time interval T2-T1.
  • Her output voltage 42, at time T2 will therefore be proportional to square of the interval T2-T1, and therefore proportional to the square of bullet speed 2 when fired. Since the distance traveled by ball 2 is itself proportional squared the initial speed of ball 2, the tension of output 42 of integrator 29 is representative of the distance traveled. It can be sent to a scaling module and display 32.
  • the calculation of the firing angle is done by an integrator 25 which receives on the one hand the slots 34 originating from the trigger 23 and on the other hand the reference voltage 31. It is controlled by the output 39 of sequencer 24. This controls this integrator 25 for a predetermined time rounded to an integer of period.
  • the integrator integrates the reference voltage 31 in one direction and when the same signal is low, said integrator integrates said reference voltage in the other direction.
  • the report cyclic of signal 34 is equal to 1, the result of this alternative integration is zero; when the duty cycle is different from 1, the result is proportional to the deviation of this cyclical report.
  • the output 43 of this integrator 25 therefore gives, with the corresponding sign, a voltage proportional to the angle shooting. This voltage is sent to the scaling module and display 32.
  • the transmitted signal by the sensors is shaped to be able to be analyzed by a microprocessor and allow the display on a screen of a part of the distance of the shot and the other part of the distance between the drop point and the perpendicular from the trajectory of reference passing through said drop point.
  • Time T2 is the signal period and is inversely proportional to the speed of the ball.
  • the T1 / T2 ratio is representative of the angle of the plane of rotation of the ball with respect to the vertical.
