DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 to FIG. 4 show a golf training device of the first preferred embodiment of the present invention.
A base member 10 in orthogonal shape has a wall 11 around three sides thereof, a vent 12 at one side, and an L-shaped ball trench 13 arranged beside the wall 11 forming the vent 12. Said base member 10 has a recess 14 in the center area and connects with the ball trench 13 by a guide way 15.
There are three elevating assemblies nonlinearly provided on said base member 10. There are an artificial elevating assembly 20 and two automatically elevating assemblies 30 in the first embodiment of present invention. Each elevating assembly has a elevating part 25, 32, respectively, that can be forced up or down by external power. These structures and actions will be discussed hereafter.
A putting green board 50 pivots on those elevating parts 25, 32 of those elevating assemblies and the sloping degree and direction can be adjusted by moving those elevating parts up or down. Said putting green board includes a ball cavity 51 for the recess 14 of the base member.
An elongated alley 60 sits on the putting green board 50 and has a hole 61 for the ball cavity 51.
A control device 70 that is a set of circuitry is provided on the base member 10 to control those automatically elevating assemblies.
A microswitch 80 sits in the guide way 15. Said microswitch will give a signal to the control device 70 for counting the point when the golf ball runs over it.
FIG. 4 shows the device of the first embodiment of present invention in the highest horizontal position.
FIG. 5 shows the device of the first embodiment of present invention in the lowest horizontal position.
FIG. 6 shows the artificial elevating assembly 20 in the highest position and the automatically elevating assemblies 30 in the lowest positions. The putting green board is inclined downwardly from the back to the vent 12 for upward putting practice.
FIG. 7 shows the artificial elevating assembly 20 in the lowest position and the automatically elevating assemblies 30 in the highest positions. The putting green board is inclined downwardly from the vent 12 to the back for downward putting practice.
FIG. 8 shows the automatically elevating assemblies 30 both in the lowest position and the putting green board is in the horizontal posture.
FIG. 9 shows the automatically elevating assembly 30 at the left side in the lowest position and the automatically elevating assembly 30 at the right side in the highest position and the putting green board 50 is inclined to the left side.
FIG. 10 shows the automatically elevating assembly 30 at the left side in the highest position and the automatically elevating assembly 30 at the right side in the lowest position and the putting green board 50 is inclined to the right side.
These two automatically elevating assemblies 30 can control the sloping degree and direction of the putting green board 50 and the degree and direction can be changed into many different practice types by using the artificial elevating assembly 20.
As shown from FIG. 11 to FIG. 15, is construction of the artificial elevating assembly 20 of the first embodiment of present invention.
A shell 21 is provided on the base member 10 at one end by studs 22 and a long chase 23 is provided downward on the shell from the top. There are many annular flutings 24 provided on the inside wall of the meta-long chase 23.
An elevating part 25 has two flexible arms 26 and receives the arms 26 in the long chase 23. Said elevating part is slidable and positionable by the flexible arms 26 and the fluting 24. The fore part of the shell 21 has two limitative parts 27 that are two long holes. Said elevating part 25 has two tappets 28 which are received in the long hole 27 to make an uppermost stop position and a lowermost stop position for the elevating part 25.
A connector 29 goes through a hole that is pre-set on the putting green board and fixes on the top of the elevating part 25.
FIG. 11 and FIG. 12 show the elevating part 25 in the uppermost stop position.
FIG. 13 and FIG. 14 show the elevating part 25 in the lowermost stop position.
FIG. 16 to FIG. 20 show the automatically elevating assemblies 30 of the first embodiment of present invention, including shell 31;
An elevating part 32 having a tubular shape is provided on the shell 31 and a rib 33 is provided on the outside of the elevating part 32 to avoid rotation of the elevating part 32 and threads are provided on the inside wall of the elevating part 32 (not shown).
A pivot 35 is provided, with threads 36 on the inside wall which correspond to the threads on the inside wall of the elevating part 32, which pivots (or rotates) in the shell 31.
A motor 37 has an endless screw 38 for meshing with a worm wheel 39 to cause a small gear 41 and a large gear 42 to rotate and to cause the pivot 35 to rotate also.
A rotator 43 is fixed on the top of the elevating part 32 by a stud 44.
A receiver 45 is fixed on the bottom of the putting green board by studs 46 and holds said rotator 43.
An elastic part 47 is provided on one side of the pivot 35 and an umbo 48 is provided at the bottom of the pivot 35. Said umbo 48 can press the elastic part 47 to touch a metal point 49 to pass a electric signal for counting the number of rotations of the pivot 35 and controlling the height of the elevating part 32.
Additionally, a microswitch 51 is provided at the lowermost stop position of said shell 31 as shown in FIG. 16 and FIG. 19 and a press arm 52 is provided at the bottom of the elevating part 32. The microswitch 51 will send a signal to stop the motor 37 when the elevating part 32 goes down to the lowermost stop position and makes the press arm 52 touch the microswitch 51. As shown in FIG. 16 and FIG. 20, there is a bearing base 53 provided at the bottom of the elevating part 32 and a microswitch 54 provided on said bearing base 53 for the uppermost stop position. When the elevating part goes up to the uppermost stop position, the microswitch 54 will touch the outer wall of the shell 31 and send a signal to stop the motor 37. Said two switches are safety switches and these switches need not always be provided in contrast to the counting function.
The device as shown in FIG. 21 and FIG. 22 is the second embodiment of present invention and three of the elevating assemblies are all artificial elevating assemblies therein for the user to adjust the sloping degree and direction of the putting green board by hand.
