Description

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 FIG. 1, a conventional upright batting apparatus is used in training course of boxing, taekwondo, or karate and contains a wooden post 1 and a plurality of supports 2 inserted around the wooden post 1 such that a user practices batting. However, such a conventional batting apparatus does not have buffer flexibility, so the user injures easily during a batting practice.
As illustrated in FIG. 2, another conventional batting apparatus contains a base 3, a buffer unit 4 fixed on the base 3, and a batting pad 5 mounted on the buffer unit 4. The buffer unit 4 is a cylindrical spring or a rubber column. During hitting the batting apparatus, the buffer unit 4 bends and recovers an original shape after the batting pad 5 is forced so as to absorb a hitting force on the batting pad 5, hence a user hits the batting pad 5 repeatedly to practice batting skill.
However, the buffer unit 4 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 4 is so soft that can not achieve a hitting effect or is so hard that will hurt the user. Also, if the buffer unit 4 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.

Another object of the present invention is to provide an adjustable batting apparatus in which the nut controls the length of the adjusting section of the screw rod 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 screw rod, and a nut. The spring is cylindrical and includes a plurality of coils, a first segment, a second segment, and the first segment or the second segment is fixed on a fixing face. The at least one batting pad is connected with the second segment or the first segment. The screw rod is axially inserted into the spring and having a first end coupled with the first segment of the spring and a second end extending out of the second segment of the spring so as to form an adjusting section. The nut screws with the adjusting section so that the nut is rotated to control a length of the adjusting section of the screw rod, hence the spring is pressed or released, thus adjusting a bending flexibility of the spring.

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. 3-7, 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 screw rod 40, and a nut 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, and a feeding hole 13. 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 14 and an outlet 15 disposed on an outer side thereof adjacent to a bottom end of the base 10. The wheel set 14 is provided to move the adjustable batting apparatus, and the outlet 15 has a lid 151 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 is arranged to fix the first segment 22 of the spring 20 on the fixing face 12 of the base 10.
The spring 20 has a second positioning piece 25 mounted on the second segment 23 thereof, and the second positioning piece 25 has a through orifice 251 defined at a central position thereof, and a diameter of the through orifice 251 is larger than that of the screw rod 40. In this embodiment, there is a batting pad 30, and the batting pad 30 is connected with the second segment 23 of the spring 20 by using the second positioning piece 25. The screw rod 40 is axially inserted into the spring 20 and has a first end 41 and a second end 42, and the first end 41 of the screw rod 40 is coupled with the first segment 22 of the spring 20, the second end 42 of the screw rod 40 extends out of the second segment 23 of the spring 20 via the through orifice 251 of the second positioning piece 25 so as to form an adjusting section 40A. The nut 50 matches with a washer 51 to screw with the adjusting section 40A of the screw rod 40 such that the washer 51 abuts against the second positioning piece 25 of the spring 20 so that the spring 20 is pressed.
As shown in FIGS. 8-10, 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 horizontally moves 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.
Furthermore, the nut 50 is rotated along the adjusting section 40A of the screw rod 40 so as to control a length of the adjusting section 40A of the screw rod 40, such that the spring 20 is pressed or released. When the length of the adjusting section 40A of the screw rod 40 increases, the spring 20 is pressed as illustrated in FIG. 9 to decrease its bending flexibility, and then a buffer flexibility effect of the batting pad 30 reduces so as to be applicable for a user who has a large hitting force and to enhance batting practice effect. Moreover, when the length of the adjusting section 40A of the screw rod 40 decreases, the spring 20 is released as illustrated in FIG. 10 to increase a distance between the plurality of coils 21 of the spring 20, and then the buffer flexibility of the spring 20 increases so that the batting pad 30 has suitable buffer flexibility effect, thus preventing the user from injure in batting practice.
Besides, the first segment 22 of the spring 20 is coupled with the batting pad 30 by ways of the first positioning piece 24, and the second segment 23 of the spring 20 is connected with the fixing face 12 of the base 10 by means of the second positioning piece 25.
