DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-4, a baseball practicing apparatus 1 in accordance with the preferred embodiment of the present invention comprises two opposite upright frames 10, two opposite longitudinal rods 40 mounted between the upright frames 10 and provided with a plurality of first emitters 41 and a plurality of first receivers 42 respectively, two opposite transverse rods 50 mounted between the upright frames 10 and provided with a plurality of second emitters 51 and a plurality of second receivers 52 respectively, two stands 11 mounted on and located under the upright frames 10, a buffer net 30 mounted around the upright frames 10 and the stands 11, an ejector 22 mounted on a bottom of the buffer net 30, and an indicator 23 mounted on a bottom of the buffer net 30.

The upright frames 10 are connected by a plurality of transverse bars 12. The bottom of the buffer net 30 is formed with a through hole 32, and the ejector 22 is formed with a through bore 21 aligning with the through hole 32 of the buffer net 30.

The longitudinal rods 40 and the transverse rods 50 are located at different positions of the upright frames 10. The first emitters 41 are mounted on one of the longitudinal rods 40, and the first receivers 42 are mounted on the other one of the longitudinal rods 40. The second emitters 51 are mounted on one of the transverse rods 50, and the second receivers 52 are mounted on the other one of the transverse rods 50.

Thus, the first emitters 41 of the longitudinal rods 40 emit a plurality of first laser beams that are received by the first receivers 42 of the longitudinal rods 40 to form a plurality of transverse sensing lines so that a transverse sensing plane 43 are defined between the longitudinal rods 40 by the first emitters 41 and the first receivers 42 of the longitudinal rods 40. Similarly, the second emitters 51 of the transverse rods 50 emit a plurality of first laser beams that are received by the second receivers 52 of the transverse rods 50 to form a plurality of longitudinal sensing lines so that a longitudinal sensing plane 53 are defined between the transverse rods 50 by the second emitters 51 and the second receivers 52 of the transverse rods 50. The longitudinal sensing plane 53 is separated from the transverse sensing plane 43.

In operation, as shown in FIG. 3, when a baseball 60 passes through the transverse sensing plane 43, the horizontal position of the baseball 60 is detected, and when the baseball 60 passes through the longitudinal sensing plane 53, the longitudinal position of the baseball 60 is detected, so that the transverse sensing plane 43 functions as the x-axis coordinate and the longitudinal sensing plane 53 functions as the y-axis coordinate to detect the planar position of the baseball 60. Thus, the planar position of the baseball 60 is detected by the transverse sensing plane 43 and the longitudinal sensing plane 53.

In addition, the velocity of the baseball 60 is determined by the time period when the baseball 60 passes between the transverse sensing plane 43 and the longitudinal sensing plane 53. The indicator 23 indicates the pitching position of the baseball 60 and the velocity of the baseball 60.

After the baseball 60 falls onto the buffer net 30, the baseball 60 in introduced into the ejector 22 through the through hole 32 and the through bore 21 and is ejected outwardly from the ejector 22 as shown in FIG. 4 for use with the user again.

As shown in FIG. 5, the baseball practicing apparatus further comprises a molding board 70 mounted between the upright frames 10 and located on a rear side of the buffer net 30. The molding board 70 has a plurality of target zones 71 to facilitate the user practicing the pitching skill.

As shown in FIG. 6, each of the first receivers 42 of the longitudinal rods 40 and the second receivers 52 of the transverse rods 50 has a front end provided with a wide-angle receiving seat 80 to receive the laser beams from the first emitters 41 of the longitudinal rods 40 and the second emitters 51 of the transverse rods 50.

Accordingly, the pitching position of the baseball is detected exactly, so that the user can judge and calibrate the pitching position of the baseball, thereby facilitating the user practicing the pitching skill. In addition, the baseball practicing apparatus detects and displays the pitching position and the velocity of the baseball simultaneously, thereby enhancing the amusement effect.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
