Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a strike trainer, and more particularly to a strike trainer for ball-type exercise, such as tennis or baseball.

2. Description of Related Art

More and more people spend time on leisure and exercise for his/her health. However, to collect the stroke ball for next strike is a hard job to a newcomer and takes a lot of time during practicing. As a result, the training effect is low and the newcomer may feel disappointed about his/her learning.

The present invention has arisen to mitigate and/or obviate the disadvantages.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an improved strike trainer that promotes the interest and the effect of learning strike.

To achieve the objective, the strike trainer in accordance with the present invention comprises a main frame adapted to abut against a supporting surface and a striking device mounted on a top portion of the main frame. The strike device includes a weighted element secured received in the top portion of the main frame and a resilient member having a first end engaged to a lower end of the weighted element. A rope has a first end securely connected to a second end of the resilient member and a resilient post having a first end secured in the top portion of the main frame and sleeved on the rope. A ball is secured on a second end of the rope after extending through the resilient post and abuts a second end of the resilient post due to a restitution force of the resilient member.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

FIG. 2 is a partially exploded perspective view of the strike trainer in FIG. 1;

FIG. 3 is a partially cross-sectional of the lateral post the base member of the present invention for showing the connection therebetween;

FIG. 4 is a cross-sectional view of a striking device of the present invention;

FIG. 5 is a cross-sectional view of a striking device of the present invention when being stricken; and

FIG. 6 is a perspective view of a strike trainer in accordance with the present invention when being folded for decreasing the volume thereof.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a strike trainer in accordance with the present invention comprises a main frame (10) adapted to abutting against a supporting surface and a striking device (50) mounted on the main frame (10).

The main frame (10) includes two lateral posts (11) each having a first end longitudinally and pivotally connected to each other. A U-shaped resilient member (12) is received in a second end of each of the two lateral posts (11) and has a protrusion (13) downward extending through the second end of each of the two lateral posts (11).

Two main posts (20) are respectively laterally secured to the second end of a corresponding one of the two lateral posts (11). The two main posts (20) are parallel to each other for upwardly supporting the striking device (50). Each main post (20) includes a wing plate (21) secured on a top thereof and having a through hole (22) defined in the wing plate (21). The protrusion (13) of each of the two U-shaped resilient members (12) is engaged into the through hole (22) of a corresponding one of the two wing plates (21) to connecting the two lateral posts (11) and the two main posts (20) and forming an H-shaped structure.

A stand post (30) is pivotally and upwardly secured on the first end of a corresponding one of the two lateral posts (11). A quick release device (31) is mounted on a free end of the stand post (30) for selectively decreasing a diameter of the free end of the stand post (30).

An inner post (40) is partially received in the stand post (30) and selectively positioned due to the quick release device (31) that is actuated to decrease the diameter of the free end of the stand post (30) when the inner post (40) is partially inserted into the stand post (30) and extends to a suitable height. One end of the inner post (40) opposite to the stand post (30) has an adjust bolt (41) screwed thereon and extending into an inner periphery of the inner post (40).

Further with reference to FIG. 4, the striking device (50) includes a weighted element (51) securely received in the inner post (40) and has a semicircle shape. The weighted element (51) has a hook (52) inwardly extending from a lower end thereof.

A resilient member (60) is longitudinally received in the weighted element (51) and has a first end connected to the hook (52) of the weighted element (51).

A rope (70) has connector (71) formed on a first thereof and securely longitudinally connected to a second end of the resilient member (60). A resilient post (90) has a first end securely received in the inner post (40) due to the adjust bolt (41) and separately sleeved on the rope (70). The rope (70) has a second end extending out of the resilient post (90) and through a ball (80). The rope (70) has stopper (72) formed the second end thereof after extending through the ball (80) to prevent the ball (80) from detaching from the rope (70) after being struck. The ball (80) abuts a free end of the resilient post (90) due to the restitution force of the resilient member (60).

With reference to FIGS. 4 and 5, the ball (80) flies away from the resilient post (90) after being struck and pulls the resilient member (60) via the rope (70). The resilient post (90) is transformed with the flying ball (80). For a period of time, the ball (80) and the resilient post (90) is reinstated to their original position due to the restitution force of the resilient member (60) and the weighted element (51) for next strike such that the user does not need to collect the stricken ball. Consequently, the interest and the effect of learning strike are promoted.

In addition, with reference to FIGS. 3 and 6, the two lateral posts (11) can be folded to abut each other and the two main posts (20) is easily detached from the two lateral posts (11) when the protrusion (13) of each of the two U-shaped resilient members (12) is disengaged from the through hole (22) of each of the wing plate (21). The stand post (30) is pivotally moved toward the two folded lateral posts (11) and the inner post (40) is partially received in the stand post (30) such that the volume of the present invention is increased to a minimum for easily being stored or moved somewhere.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
