Description

[Detailed explanation of the invention] Conventional swing practice equipment using rubber mats include rotary equipment in which the shaft of an arm with a ball fixed to the tip is fixed to one end of the rubber mat, or a swing practice equipment using a combination of a rope and a spring. There are various types, such as those whose parts are fixed to a rubber mat, those that use an elastic synthetic rubber string instead of a rope to pull the ball closer to the player's hand, and those that have a rotating arm attached to a cast iron base instead of a rubber mat, but none of them work. It is easy to move because it is repeatedly hit, so to prevent this, it must be heavy and large, which increases cost and is inconvenient to carry.The rope is also thin and there is a risk of breakage. This invention provides a lightweight and inexpensive swing practice tool using a sturdy rope that presses the front end of a rubber mat so that it does not move, curves the front half into a semi-elliptical shape to absorb shock, and then restores its original shape.

One embodiment of the present invention will be explained with reference to the drawings.
is a rubber mat, 2 is a piece of rubber plate for cushioning, 3 is a ball, and 4 is a rope. Rubber mat 1 is a band-shaped natural rubber plate, with a rectangular rubber plate piece 2 near the front end.
A countersunk machine screw 6 with a rubber ring 5 fitted to the lower end
At the rear end of the rubber plate piece 2, a hole 7 for attaching a rope 4 to which a ball 3 is fixed at the tip is bored.
The rope 4 is inserted and tied in a bent shape, and the length is adjustable with a margin, and the excess rope is left hanging.

To use the present invention, when the ball 3 is swung, the rope 4 is pulled by the hit ball, and the rubber plate piece 2 is tilted forward with the rubber ring 5 at the lower end of the countersunk screw 6 as a fulcrum, and the rubber mat 1 The front end of the ball 3 is pressed down to prevent it from moving, and the reaction causes the front half to float upward in a semi-elliptical shape and curve, causing the ball 3 to hit the floor in front of it, and the rope When the tension of 4 is lost, the rubber plate piece 2 is reversed and the rubber mat 1
The rubber mat 1 is pushed backward and the semi-elliptical shape is restored to approximately half the plane, and due to continuous swinging, the semi-elliptical serpentine state movement is repeated and the rubber mat 1 does not move back and forth as a whole.

If the rubber plate piece 2 for cushioning is directly connected to the rubber mat 1 with the rope 4, it will be easier to move during swinging, and the impact will be less if it is via the rubber plate piece 2, and the rubber plate piece 2 can be tilted forward to make the rubber mat 1 into a semi-elliptical shape. Because it is curved to
Of course, it is possible to change the dimensions in kg as appropriate.

If the rubber plate is thin, it is stored rolled up, but depending on the flexibility of the rubber, it is often curved.If it is thin, it will easily return to its flat shape, but if it is thick, it will be difficult. The 6 mm of the example restores its original shape, but in order to form a semi-elliptical shape when swinging, it is necessary to curve the rubber a little and raise the front end, so the plate connecting the rubber mat 1 and the rubber plate piece 2 is The rubber ring 5 at the lower end of the machine screw 6 is made to protrude downward from the bottom surface of the rubber mat 1 to raise the front end and form a curved surface. However, if a slightly curved rubber mat 1 of 8 to 9 mm is used, Since it is difficult to restore to a flat shape, by making use of this and forming a curved surface so that the front half floats, the countersunk machine screw 6 fitted with the rubber ring 5 does not need to protrude from the bottom surface of the rubber mat 1. When the rubber ring 5 is removed, the entire bottom surface has a slightly raised front part, but the rest becomes substantially flat.

The rope 4 and the ball 3 are connected by using a hollow ball 3 and drilling a through hole 8 in the rope 4.
The ends of the rope 4 are dispersed, the inserted ends are made to protrude into the hollow part, the through hole 8 of the rope 4 is placed on the lower side, and an adhesive injection port 9 is drilled and injected in the upper part opposite to this. Permeate the dispersed ends and dry and fix.
It was made impossible to escape.

As mentioned above, with this project, the pole and rope do not come apart like in the past, and the rope is strong and stable without worrying about it breaking, allowing you to concentrate on swinging, being light and convenient to carry, and being able to be used both inside and outside the room. It is not only suitable for swinging wood and iron, but also many people are using golf swing as a healthy exercise to prevent lack of exercise and aging, and if you use this idea, it will keep you interested and last for a long time. The practical effects are great.

Claims (1)

[Scope of utility model registration request] The front end of a rubber plate piece 2 for cushioning during swinging is attached to one end of the rubber mat 1, and a rope 4 with a ball 3 fixed to the tip is connected to the rear end of the rubber plate piece 2. The rubber plate piece 2 tilts forward in a rotational manner, and its front end presses the rubber mat 1 to prevent it from moving forward, and in reaction, the front half of the rubber mat 1 curves upward into a semi-elliptical shape, causing an impact. This golf practice tool is characterized by absorbing and relaxing the rubber mat 1, automatically restoring itself in a bellows shape after a swing, and preventing movement of the rubber mat 1.
