BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a batting apparatus, and more particularly to an adjustable batting apparatus which is capable of adjusting a desired buffer flexibility based on a user's hitting force and using requirement.
2. Description of the Prior Art
Referring to FIGS. 1 and 2, a conventional upright batting apparatus is used in training course of boxing, taekwondo, or karate and contains a base 1, a buffer unit 2 fixed on the base 1, and a batting pad 3 mounted on the buffer unit 2. The buffer unit 2 is a cylindrical spring as shown in FIG. 1 or a rubber column as illustrated in FIG. 2. During hitting the batting apparatus, the buffer unit 2 bends and recovers an original shape after the batting pad 3 is forced so as to absorb a hitting force on the batting pad 3, hence a user hits the batting pad 3 repeatedly to practice batting skill.
However, the buffer unit 2 of the upright batting apparatus has a fixed bending flexibility without being adjusted according to the user's hitting force or using requirement. In addition, the buffer unit 2 is so soft that can not achieve a hitting effect or is so hard that will hurt the user. Also, if the buffer unit 2 is a rubber column, it will break easily, thus lowering using life.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an adjustable batting apparatus in which a rolling device controls a length of an extending section of a belt so as to adjust a distance between a plurality of coils of a spring, hence a bending flexibility of the spring is adjusted based on using requirement and a user's hitting force, thus obtaining the buffer flexibility effect.
Another object of the present invention is to provide an adjustable batting apparatus in which the rolling device controls the length of the extending section of the belt so as to adjust the bending flexibility of the spring easily.
An adjustable batting apparatus in accordance with the present invention contains: a spring, at least one batting pad, a belt, and a rolling device.
The spring is cylindrical and including a plurality of coils, a first segment, a second segment, and the first segment is fixed on a fixing face of a base. The at least one batting pad is connected with the second segment. The belt has a first end coupled with the second segment of the spring and has a second end. The rolling device has the second end of the belt rolled therearound, and a part of the belt extends out of the rolling device so as to form an extending section, such that the rolling device controls a length of the extending section of the belt so as to adjust a distance between the plurality of coils of the spring, hence a bending flexibility of the spring is adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
With reference to FIGS. 3-8, an adjustable batting apparatus according to a preferred embodiment of the present invention comprises: a base 10, a spring 20, at least one batting pad 30, a belt 40, and a rolling device 50, wherein the base 10 is a hollow cylinder and includes a receiving chamber 11 defined therein, a fixing face 12 formed on a top end thereof, a feeding hole 13, and a recessed portion 14. The feeding hole 13 has a cover 131 for covering onto or removing from the feeding hole 13 and is used to feed water or sands into the receiving chamber 13 so that the base 10 has a certain weight and is fixed securely. The base 10 also includes a wheel set 15 and an outlet 16 disposed on an outer side thereof adjacent to a bottom end of the base 10. The wheel set 15 is provided to move the adjustable batting apparatus, and the outlet 16 has a lid 161 covered thereon or removed therefrom so as to discharge the water or the sands out of the receiving chamber 11. The spring 20 is cylindrical and includes a plurality of coils 21, a first segment 22, a second segment 23, and a first positioning piece 24 fixed on the first segment 22. The first positioning piece 24 has a first horizontal bar 241 for fixing the first segment 22 of the spring 20 on the fixing face 12 of the base 10 by ways of the first positioning piece 24.
The spring 20 has a second positioning piece 25 mounted on the second segment 23 thereof, and the second positioning piece 25 has a second horizontal bar 251 secured thereon. In this embodiment, there is a batting pad 30, and the batting pad 30 is connected with the second segment 23 of the spring 30 by using the second positioning piece 25. The belt 40 has a first end 41 and a second end 42, and the first end 41 is coupled with the second horizontal bar 251 of the second positioning piece 25 via the first horizontal bar 241 of the first positioning piece 24 and the second segment 23 of the spring 20 from the first segment 22 of the spring 20 so that the spring 20 is pulled and pressed by the first end 41 of the belt 40, and the second end 42 of the belt 40 is rolled around the rolling device 50 and a part of the belt 40 extends out of the rolling device 50 so as to form an extending section 40A. In this embodiment, the rolling device 50 is a hand puller fixed on the recessed portion 14 of the base 10.
As shown in FIG. 9, in operation, the adjustable batting apparatus is erected on the ground by using a weight of the base 10, and the user's hits the batting pad 30 with hands or legs, thereafter the spring 20 deforms and recover an original shape such that the batting pad 30 swings relative to the base 10 so as to absorb a hitting force on the batting pad 30. Thereby, the user hits the batting pad 30 repeatedly so as to practice batting.
With reference to FIGS. 10 and 11, the rolling device 50 is operated to increase or to decrease a length of the extending section 40A of the belt 40 so as to further control a distance between the plurality of coils 21 of the spring 20, hence a bending flexibility of the spring 20 is reduced and a buffer flexibility effect of the batting pad 30 is lowered so as to match with a user who has a large hitting force and to enhance batting practice effect. As desiring to increase bending flexibility of the spring 20, the second end 42 of the belt 40 is released from the rolling device 50 so as to recover an original length of the spring 30, and then the rolling device 50 is rolled to decrease the length of the extending section 40A of the belt 40 so as to reduce the distance of the plurality of coils 21, thereafter the spring 20 is adjusted to a desired bending flexibility so that the batting pad 30 has suitable buffer flexibility effect.
As illustrated in FIG. 12, the second positioning piece 25 of the second segment 23 of the spring 20 has outer threads 252 arranged around an outer peripheral side thereof so as to screw with inner threads 311 of a socket 31 of the batting pad 30, such that the spring 20 is screwed with the batting pad 30, thus rotating the batting pad 30 to a desired height. Referring further to FIG. 13, the spring 20 had a protective sleeve 60 fitted thereon so as to protect the spring 20.
Thereby, the adjustable batting apparatus of the present invention has the following advantages:
1. The rolling device 50 controls the length of the extending section 40A of the belt 40 of the adjustable batting apparatus so as to adjust the distance between the plurality of coils 21 of the spring 20, hence the bending flexibility of the spring 20 is adjusted based on using requirement, thus obtaining the buffer flexibility effect.
2. The rolling device 50 controls the length of the extending section 40A of the belt 40 of the adjustable batting apparatus so as to adjust a bending flexibility of the spring 20 easily.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
