1. Field of the Invention
The present invention relates to a swing trainer, and more particularly to a swing trainer for exercise that is adjusted easily based on using requirement.
2. Description of the Prior Art
Baseball and softball is a sport including movements of pitching, hitting, base running, and passing, wherein hitting may get scores so as to win the game finally.
To train a hitting skill, a user can hit baseballs pitched from a pitching machine, or the baseball or the softball is placed on a batting seat to hit the baseball or the softball. In addition, a swing weight is fitted on a hitting end of a bat to increase a weight of the bat, thus training swing force and speed. However, such a swing weight is fixed on the hitting end of the bat without being adjusted based on using requirement. Therefore, users with different arm forces cannot adjust a fixing position of the swing weight on the bat to grow muscles and improving hitting skill. Furthermore, since the swing weight is fitted on the hitting end of the bat, the swing weight slides on the bat as swinging the bat randomly and damaging the baseball.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a swing trainer for exercise in which a body and a handle are capable of being rotated relative to each other, such that a counterweight block axially moves toward a desired position along the body, thereafter the farther the counterweight block away from the handle is, the more the swing force forced by a user, yet the closer the counterweight block moves toward the handle, the less the swing force forced by the user based on the lever principle. Accordingly, the swing trainer is capable of being adjusted to be applicable for different users with different swing force and growing the different users' muscles.
Another object of the present invention is to provide a swing trainer for exercise in which the counterweight block is fixed in the body and is screwed with a screw rod of the handle, such that the body and the handle are rotated relative to each other so that the counterweight is driven to axially move along the body, hence the counterweight block will not slide randomly and will not damage a baseball.
A swing trainer for exercise in accordance with a preferred embodiment of the present invention contains:
a handle having a first end and a second end relative to the first end, and the second end having a screw rod extending outwardly therefrom;
a body formed in a hollow cylinder shape and having a first segment and a second segment relative to the first segment, the first segment fitting with the second end of the handle, and the screw rod being inserted into the body, between the first segment and the second segment of the body being axially defined a defining rail;
a counterweight block formed in a circular loop shape and fixed in the body, the counterweight block having a first screw orifice defined on a central position thereof to screw with the screw rod of the handle and a slot axially defined on a side of an outer surface thereof to match with the defining rail of the body;
a limiting member for limiting a connection of the handle and the body so that the handle moves relative to the body.
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.
Between the second end 12 of the handle 1 and the first segment 21 of the body is defined a rotary positioning means. The rotary positioning means includes an abutting unit 123 disposed on the fitting extension 122 of the second end 12 of the handle 1, wherein the abutting unit 123 is an assembly of a spring and a ball in this embodiment, the rotary positioning means also includes a plurality of arcuate notches 212 formed around a bottom end of the recess 211 to abut against the abutting unit 123 so that the body 2 allows rotating relative to the handle 1.
In operation, as shown in
Thereby, the swing trainer for the exercise of the present invention has the following advantages:
1.The body 2 and the handle 1 of the swing trainer are capable of being rotated relative to each other, such that the counterweight block 3 axially moves toward the desired position along the body 2. Thereafter, the farther the counterweight block 3 away from the handle 1 is, the more the swing force forced by a user, yet the closer the counterweight block moves toward the handle 1, the less the swing force forced by the user based on the lever principle. Accordingly, the swing trainer is capable of being adjusted to be applicable for different users with different swing force and growing the different users' muscles.
2.The counterweight block 3 is fixed in the body 2 and is screwed with the screw rod 13 of the handle 1, such that the body 2 and the handle 1 are rotated relative to each other so that the counterweight 3 is driven to axially move along the body 2, hence the counterweight block 3 will not slide randomly and will not damage a baseball.
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.
