Definitions

  • the subject of the present invention is an auxiliary light device for golf training, in particular for putting or putting training comprising a light beam emitter and an optical system arranged to diffuse said beam in a plane, the transmitter and the optical system being fixed to a golf club so that the beam scattering plane is perpendicular to a striking surface of the club and forms a light trace on the ground.
  • the golf ball is struck by means of a special stick called a "putter", having at its end a relatively wide iron whose striking surface will be approximately vertical at the time of contact with the ball .
  • the main difficulty in "putting” consists in orienting the striking surface of the iron along a plane perpendicular to the vertical plane passing through the center of the ball and through the center of the hole. In practice a player can acquire the habit of correctly orienting the iron only by repeating many shots in training, because it is only the direction followed by the ball that will show him if the position of the iron was correct or not.
  • Known driving devices comprise, on the head of the "putter", one or more light diodes each emitting a linear beam in a direction perpendicular to the striking surface, which allows the player to place the stick in an ideal stopped position.
  • a device is hardly useful during the movement of the stick, since the trace of each beam on the ground is a point which, at this moment, moves too quickly for the player to be able to use it in sight to correct his gesture.
  • US Patent No. 3,953,034 relates to an auxiliary device mounted on a golf club for training in "swing".
  • a linear laser beam emitted by a source attached to the handle, strikes a convex mirror placed at the bottom of the handle next to the striking surface.
  • the laser light is reflected forward in the form of a vertical plane beam perpendicular to the striking surface, creating on the ground a light trace which visualizes a direction parallel to the likely trajectory of the ball.
  • such a device makes it possible to verify only the horizontal orientation of the striking surface, but not other parameters of the position of this surface, in particular a possible lateral offset relative to the ball.
  • the present invention aims to improve a device of the kind indicated above, so that it can be used for training in "putting” and allows to better visualize the ideal position of the stick when it will strike the ball.
  • the device according to the invention is characterized in that the beam scattering plane passes through a point of impact of the bullet on the striking surface, and in that the optical system is located behind a plane defined by the striking surface.
  • the optical system can advantageously be located higher than the striking surface, so that part of the scattered beam always passes over the ball.
  • the light beam is a beam parallel to the output of the emitter, which can be a laser emitter, and the optical system comprises a cylindrical lens.
  • the device may include a source of electrical energy supplying the transmitter and fixed to the stock.
  • the optical system is integral with the transmitter, which is mounted on an adjustable arm removably attached to the handle of the stick.
  • the optical system comprises a reflector secured to the cylindrical lens and is located at a distance from the emitter.
  • the transmitter can be arranged along the handle of the stick or be incorporated into this handle.
  • the butt 1 comprises a handle 5 provided with a handle 6 and fixed at its end lower, to an iron 7 of special shape having, opposite the ball 2, a striking surface 8 which is generally flat and which, when it strikes the ball, should normally be vertical if the player holds the stick correctly.
  • a marking notch 9 formed on the iron 7 indicates where the middle of the striking surface 8 is located, that is to say the ideal point 10 of impact of the surface 8 against the ball 2.
  • the plane of the striking surface 8 is assumed to be vertical; it is represented by its trace Y on the ground and by a vertical axis Z passing through point 10.
  • a third axis X orthogonal to the axes Y and Z represents the line normal to the surface 8 at the point of intersection of the axes Y and Z
  • the X axis follows the ground 3, since the surface 8 is vertical, and the XZ plane passes through the center of the ball 2 and through the center of the hole 4 since it is in this direction. you want to roll the ball 2.
  • the device according to the invention is removably mounted on the stock 1. It comprises an optical and electronic unit 11, a support 12 removably attached to the handle 5 and supporting the unit 11 in an adjustable position, a power supply unit 13 fixed to the handle 5 by means of flanges 14, and a pair of electrical conductors 15 connecting the blocks 11 and 13.
  • the block 11 contains a red coherent beam emitter constituted by a laser diode 16 emitting in the 670 nm band.
  • Block 11 also contains an electronic circuit controlling the operation of this diode.
  • the laser diode 16 emits a parallel light beam which strikes a cylindrical lens 17 whose axis is parallel to the Y axis, that is to say that this lens has the effect of dispersing the parallel beam into a diverging plane beam 18 located in a vertical plane parallel to the XZ plane.
  • the block 11 is arranged so that the beam 18 is precisely in the plane XZ and is directed downward and in front of the iron 7. Consequently the beam 18 will form, on the ground 3, a rectilinear light trace 19 which, in the position shown, coincides with the axis X. More generally, trace 19 represents the intersection of the vertical plane XZ with the ground 3 and shows therefore to the player the theoretical trajectory that the ball 2 will follow according to the orientation of the striking surface 8, if the ground is perfectly horizontal.
  • the support 12 is fixed to the handle 5 by means of a clamp 21 equipped with a wing nut 22 or by means of a pressure or bayonet fixing device, which allows it to be easily mounted in the desired position on any stick or "club". This allows the same device to be used with different types of irons.
  • the power supply unit 13 can possibly be incorporated in the unit 11 or fixed on the support 12.
  • the device comprises a transmitter block 24 which is fixed to the handle 5 of the stock 1 by clamps 23 and which emits a coherent and parallel light beam 25 towards a block optical 26 carried by a support 27 fixed to the iron 7.
  • the transmitter unit 24 contains a laser diode 28, an energy source such as a battery 29, and the electronic circuits for controlling the laser diode.
  • the optical unit 26 is in the form of a small housing provided with an upper window 30, a cylindrical lens 31 and an internal reflector (not shown) arranged so as to reflect the parallel laser beam 25 in the plane XZ in the direction of the cylindrical lens 30.
  • the latter is arranged in the same manner as in the previous example, to form the diverging light beam 18 directed downward in the vertical plane XZ.
  • this construction has the advantage of concentrating on the handle the majority of the mass of the device.
  • the angle of inclination of the parallel beam 25 relative to the handle 5 can be constant.
  • the beam 25 is centered in the window 30 by adjusting the position of the block 24 along the handle.
  • a device allows a player to see in advance, thanks to the light trace 19, the initial trajectory that the ball will follow and therefore to quickly learn to give the stick the desired position as well as correcting the positioning of the hands on the handle of the "putter".
  • the constructions described make it possible to place the optical units 11 and 26 entirely behind the plane YZ of the striking surface 8, so that they do not at any time interfere with the view of the player towards this surface 8, ball 2 or marker 9.
  • a stick fitted with this device allows you to exercise "putting" on any floor, in particular on an artificial floor such as a carpet, which allows a player to train at home or in a gym.
  • the present invention is not limited to the embodiments described above, but it extends to any modification or variant obvious to a person skilled in the art.
  • the reference 32 indicates a possible position of the light beam emitter and the electric battery inside the handle.
  • the light beam can be created by different types of emitters, insofar as it can be collimated in a plane and where it has a recognizable color on the ground.
