Abstract

PURPOSE:To provide a golf exerciser which enables a mat on which to place a golf ball in a golf training place to be freely adjusted not only to a flat plane but also to such slopes as raising or lowering the left leg or having an up- or down-gradient in the forward direction so as to enable a way of hitting corresponding to a lie in a true golf course to be learned. CONSTITUTION:Two sides of a base having a perpendicular face are mounted in the notched portions 2,3 of a fixed frame 1 in such a manner as being rotatable by support shafts 4,5, the inside of the frame 1 being perpendicularly notched, and the base 10 is rotated vertically about the support shafts 4,5 so that conditions of such slopes as raising or lowering the left leg or having an up- or down-gradient in the forward direction are provided.

d and 5d, and by operating the foot pedals 8 and 9, the motor moves forward and backward. Furthermore, one of the connecting pieces 4c and 5c is formed in a concave portion 4e, and the other connecting piece 5c is formed in a concave portion 4e.
has a hook shape, and the end of the support shaft 5 is attached to the bent portion, and the connecting piece 5c itself is set at a position above the recessed portion 4e. Reference numeral 10 is a rectangular base having two hinges 11 and 12 on each of two orthogonal sides.
1 and 12 are respectively engaged with the recesses 2 and 3 cut out in the cutouts 1a and 1b of the fixed frame 1, and the long axes 4a of the support shafts 4 and 5
, 5a, the short shafts 4b, 5b are engaged, and the base 10 is fixed to the fixed frame 1.
It is joined to. Reference numeral 13 denotes a lifting device constituted by a jack installed under the base 10, and the fixed frame 1
It is operated by a manual handle 14 attached to the base 10 to move the base 10 up and down. In the figure, 15 indicates a golf mat, and 16 indicates a ball case.

[0006]

[Operation] The device of the present invention has a base 10 as shown in FIG.
When the support shafts 4 and 5 are engaged with the hinges 11 and 12 of the base 10, the base 10 remains horizontal and you can practice in the same way as in a conventional practice field. When it is pushed in, the support shaft 4 connected to the lever 8a moves back and the base 1
0 is disengaged from the hinge 11, and in this state, when the manual handle 14 is rotated and the base 10 is pushed up with the lifting device 15, the base 10 rotates upward about the support shaft 5 (long axis 5a, short axis 5b). When the lifting device 13 is lowered, the base 10 rotates downward to form a slope condition with the left foot going down. In this state, the connecting piece 4c of the support shaft 4 moves backward, and the base of the short shaft 4b of the support shaft 4 is set at the position of the connecting piece 5c of the support shaft 5, and serves as a stopper. is restricted by the base end of the short shaft 4b of the support shaft 4, making it impossible to depress the foot pedal 9. Next, the lifting device 13 is activated to return the base 10 to the horizontal position, and when the foot pedal 8 is stepped backward, the support shaft 4 moves forward, and the long shaft 4a and the short shaft 4b engage with the respective hinges 11. The concave portion 4e of the connecting piece 4c of the support shaft 4 is set at the position of the connecting piece 5c of the support shaft 5, and the stopper function of the short shaft 4b of the support shaft 4 with respect to the connecting piece 5c is released. Furthermore, when the foot pedal 9 is stepped forward in the state shown in FIG. When the base 10 is raised, the base 10 rotates upward using the support shaft 4 (long axis 4a, short axis 4b) as a fulcrum, forming a front upward slope.On the other hand, when the base 10 is rotated downward, the front downward slope is formed. When the support shaft 5 is retracted, the base end of the short shaft 5b including the connecting piece 5c is set in the concave portion 4e of the connecting piece 4c of the support shaft 4, so that the support shaft 4 It serves as a stopper, so when the hinges 11, 12 of the base 10 and either of the support shafts 4, 5 are disengaged, the other support shaft cannot move forward or backward, and the base 10 will not fall off from the fixed frame 1. Note that the movement of the support shafts 4 and 5 back and forth and the operation of the manual handle 14 may be performed not only manually but also electrically.

Effects of the Invention As described above, the present invention has a fixed frame having two orthogonal notches on the inside, and two orthogonal surfaces corresponding to the notches on the two sides, and a base that is removably mounted on the notch with a support shaft and is rotatable back and forth and left and right about the support shaft, and an elevator that is installed under the base and moves the base in the vertical direction. The base can be easily set up on a slope with the left foot, down with the left foot, up with the front up, and down with the front, making it possible to practice hitting on a slope that corresponds to an actual golf course. This has the advantage of allowing detailed and extremely practical practice to be carried out.
