Referring to the drawings and initially to
The top of the stand 2 is provided with a support seat 21 having a central portion formed with a substantially cone-shaped concave portion 22.
The housing 3 is angle adjustably mounted on the top of the stand 2. The housing 3 has a first face provided with a switch assembly 34 and a second face provided with a battery compartment 33 to receive a battery 330 which supplies an electric power to the motor 31. The top of the housing 3 has a mediate portion formed with an opening 300. The top of the housing 3 has a first side provided with two outwardly extending transverse stubs 35 and a second side formed with a slideway 36 and a screw bore 360. The housing 3 has a bottom provided with a substantially arc-shaped convex portion 37 rotatably mounted on the concave portion 22 of the support seat 21 of the stand 2 by an adjusting device 30. The convex portion 37 of the housing 3 is formed with an adjusting slot 370 which is substantially arc-shaped.
The adjusting device 30 includes a substantially arc-shaped fixing plate 38 disposed in the housing 3 and rested on the convex portion 37 of the housing 3, and a threaded rod 39 extended through the support seat 21 of the stand 2, the adjusting slot 370 of the housing 3 and screwed into the fixing plate 38 to secure the housing 3 to the support seat 21 of the stand 2. The fixing plate 38 has a top provided with a locking nut 380 screwed onto the threaded rod 39. Thus, the threaded rod 39 is movable in the adjusting slot 370 of the housing 3 when the housing 3 is rotatable relative to the stand 2.
The feeding member 4 is angle adjustably mounted on the top of the housing 3. The feeding member 4 has a cylindrical shape and has a mediate portion having a peripheral wall formed with an opening 47 facing the opening 300 of the housing 3. The feeding member 4 has a first side provided with two hooks 41 hooked onto the transverse stubs 35 of the housing 3 respectively and a second side provided with a movable plate 42 movably mounted in the slideway 36 of the housing 3 and having an elongated adjusting slot 43 aligning with the screw bore 360 of the housing 3. The feeding member 4 has a first end formed with an entrance 45 and a second end formed with an outlet 46 to allow passage of a baseball (or softball) 40.
A threaded rod 44 is screwed into the screw bore 360 of the housing 3 and extended through the adjusting slot 43 of the movable plate 42 of the feeding member 4 to secure the feeding member 4 to the housing 3. Thus, the threaded rod 44 is movable in the adjusting slot 43 of the movable plate 42 of the feeding member 4 when the movable plate 42 of the feeding member 4 is movable relative to the threaded rod 44.
The ball throwing wheel 32 is extended through the opening 300 of the housing 3 into the opening 47 of the feeding member 4 as shown in
As shown in
As shown in
Thus, the housing 3 together with the feeding member 4 is rotatable relative to the stand 2 about the threaded rod 39 to rotate the outlet 46 of the feeding member 4 horizontally through 360 degrees so as to adjust the direction of the outlet 46 of the feeding member 4.
Alternatively, the housing 3 together with the feeding member 4 is rotatable relative to the stand 2 about a horizontal axis to move the outlet 46 of the feeding member 4 upward as shown in
Accordingly, the hooks 41 of the feeding member 4 are hooked onto the transverse stubs 35 of the housing 3, the movable plate 42 of the feeding member 4 is inserted into the slideway 36 of the housing 3, and the threaded rod 44 is screwed into the housing 3 and extended through the movable plate 42 of the feeding member 4 to secure the feeding member 4 to the housing 3, so that the feeding member 4 is mounted on and detached from the housing 3 easily and quickly by rotation of the threaded rod 44, thereby facilitating the user assembling and disassembling the feeding member 4. In addition, the feeding member 4 is pivotally movable relative to the housing 3 to change the travel speed of the ball 40 injected from the outlet 46 of the feeding member 4. Further, the housing 3 together with the feeding member 4 is rotatable relative to the stand 2 about a vertical axis to rotate the outlet 46 of the feeding member 4 horizontally through 360 degrees so as to adjust the direction of the outlet 46 of the feeding member 4. Further, the housing 3 together with the feeding member 4 is rotatable relative to the stand 2 about a horizontal axis to move the outlet 46 of the feeding member 4 upward and downward so as to adjust the angle of the outlet 46 of the feeding member 4.
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.
