• the qwi ball return mechanism is described in this short version, is particularly complicated and therefore expensive and prone to failure. Furthermore, the apparatus comprising such a mechanism can only be used for swing training and it cannot be easily adapted to the practice of putting.
• the present invention aims to remedy these drawbacks by providing a device of particularly simple design, requiring little maintenance at low cost and allowing golf training in the best conditions.
• this golf practice training device comprising a substantially rectangular box of small thickness, placed on the ground, and the upper face of which has an opening through which passes a cable fixed to a golf ball capable of be placed on the upper surface of the case, so that it can be struck by the player, and, inside the case, a mechanism driven by an electric motor to ensure the recall of cable and its storage in accumulated form, under the command an electric motor power switch ac tionnable by the player, is characterized in that the cable return mechanism comprises means for leaving run the cable freely backwards when it is driven by the ball struck by the player and on the contrary to push the cable forward, directly from a magazine housed in the housing and in which the cable is accumulated by being coiled freely on itself, in a random manner, when the player presses the interrupter.

• FIG. 5 is a view in vertical section and partial longitudinal view taken along the line V-V of FIG. 4.
• Figure 6 is a perspective view of the apparatus suitable for training in putting.
• the apparatus for training in the practice of gol comprises a housing 1 for the practice of large shots and approach shots.
• This box 1, of rectangular shape, is made up of two anterior 2 and posterior parallelepipedic parts 3 of the same dimensions, articulated, along two adjacent small sides around a transverse hinge 4.
• the two articulated parts 2 and 3 of the housing 1 are advantageously re covered, partially or entirely, with a layer of synthetic grass 5 applied to their upper horizontal faces, when the housing 1 is deployed and the two parts 2, 3 are aligned one with the the horizontal on the ground, these two faces coming into contact one on the other when the housing 1 is folded.
• the front part 2 carries wn tee 7, constituted by wn twbe section, standing vertically above the upper face 2a of this part and on which can be placed a golf ball 8 so that it is raised by relative to the upper face 2a of the front part 2 of the housing.
• the apparatus according to the invention also includes a step 9 which is necessary so that the player is located at the correct height with respect to the ball 8.
• C step 9 the same thickness as the main housing 1 is in the form of 'a parallelepipedic tank, advantageously also covered with a layer 5 of synthetic gas on its upper face.
• This step 9 can advantageously be housed inside the rear posterior part 3 of the housing 1, when the latter is folded back into the closed position.
• the rear part 3 of the housing 1 has, in its upper face 3a, a hole 10 allowing the practice of putting as will be described later.
• a protective net 11 is fixed to the rear part 3, this file extending upwards, from the longitudinal sides e of the rear transverse side of the rear part 3 For transport this net 11 advantageously folds up. inside the housing 1.
• the front part 2 of the housing contains a mechanism which ensures, after the execution of a swing, the stroke of the ball 8 in the starting position.
• This mechanism includes a cable 12 which is attached to the ball 8 and which extends through an opening 13 provided in the upper face 2 of the front part 2 of the housing. As can be seen in FIGS.
• the tee 7 is articulated, at its lower part, about a horizontal and transverse axis 14
• This axis 14 is advantageously constituted by a spreading rod passing right through the tee tubular 7, extending transversely between a side wall and a longitudi ⁇ nal 2b of the part 2 of the housing and the front face of a transverse screw 15, on which it is supported, this screw 15 being screwed into the other side wall and longitudinal 2c of part 2 of the housing.
• the rod 14 passes through the vertical slots of two guide pieces longitudina ⁇ the 15 in the shape of an inverted U, which are fixed at the bottom 2d of the front part 2, on either side of the tee 7.
• the cable 12 extends, starting from the ball 8, lengthwise through the twbwlaire tee 7, it passes under a pin d transverse support 16 being located at approximately mid-length of the tubular tee 7 and above the articulation axis 14 of the tubular tee 7, and it leaves it through a longitudinal slot 17 formed in the lower and anterior part of the tubular tee 7 and extending to its lower end. From there the cable 12 passes between an upper backpressure cylinder 18 and a lower drive cylinder 19, these two cylinders being arranged one above the other and each having a horizontal axis and transver ⁇ sal.
• the lower drive cylinder 19 is coupled to the output shaft of at least one drive motor 20 (in this case two opposite motors 20 in the form of e ⁇ xecution shown).
• the cable 12 then enters a storage magazine 21 in which it is coiled in a random manner and it is fixed at its end.
• the upper counterpressure cylinder 18 is fixed under a rectangular mobile plate 22 which extends in a part of the opening 13 provided in the upper horizontal face 2a of the front part 2 of the housing 1. This mobile plate 22 s extends
• the movable plate 2 is articulated, along its front edge, on the upper fac 2a of the part 2 of the housing 1, by the intermediary of a transverse hinge 23 and it thus forms a pedal on which the player can press. . It has in its rear part, a longitudinal notch 24 which opens into its rear edge and which is sufficiently wide to allow passage through it of the tubular tee 7, when the latter comes to occupy its vertical position which is shown in line mixed in figure 2.
• a protective cradle 25 is arranged just below the lower drive cylinder.
• a contactor 26 which controls the supply of the electric motor or motors 20. Furthermore, the movable plate 22 is normally maintained in its horizontal position, as shown in FIG. 2, by means springs 27 bearing on the bottom 2d of part 2 of the housing and under the plate 22. In the horizontal position the movable plate 22 is thus flush with the rest of the upper face 2a of part 2 of the housing.
• the player places the ball 8 on the upper end of the tubular tee 7 which is then in a vertical position, as shown in dashed line in Figure 2.
• This position can be adjusted in height by action on the screw 15 controlling the arching of the rod 14.
• the ball 8 is thrown back towards the net 11 and it carries with it the cable 12 to which it is attached.
• This movement causes a tilting of the tubular tee 7 in the opposite direction to the pins of a watch under the action of the cable 12 which is drawn. by the ball 6 towards the rear, that is to say to the left in FIG.
• the part of the cable 12 which is located downstream of the two cylinders 18,19, is thus repressed and forced to penetrate in the storage magazine 21 in which the cable coils on itself in a completely random manner.
• the cable is prevented from sliding relative to this tubular tee 7 and the tensile force exerted on the cable 12 causes, due to the fact that the pin support 16 is located above the pivot axis 14, a pivoting movement of the tubular tee 7 and of the ball 8 which it carries, in a clockwise direction, to bring it into a vertical position of departure.
• FIG. 6 illustrates the way in which the device according to the invention can be adapted for e tracing to putting.
• the rear part 3 of the box 1, which is provided with the hole 10 is used and this part 3 is used with other similar rectangular boxes 3 also each provided with a hole 10, this boxes extending perpendicularly either to a short side or to a large side of the rear part 3.
• Obstacles 28 can be fixed in appropriate places on the surfaces of the boxes, in order to allow the player to choose at will the difficulty of his course.
• Removable covers 29 can be used to plug certain holes 10 as desired.
• the device according to the invention also has a movable part 30 of triangular shape allowing the connection of adjacent boxes which are connected at an angle so as to constitute any course.
