A golf practicing device includes a housing, an electromagnet mounted in the housing, a cover rotatably mounted on the housing, a magnetic block secured on the cover and aligning with the electromagnet, and a bar mounted on the cover for rotating the cover when the bar is hit. Thus, the energized electromagnet produces a magnetic force to magnetically attract and move the magnetic block to return the bar to the original position, so that the bar can be restored to the original position automatically, thereby facilitating the user practicing the golf skill.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a golf practicing device, and more particularly to a golf practicing device having an automatic restoring function.




2. Description of the Related Art




A conventional golf practicing device comprises a rotation disk, and a bar having a first end mounted on the a rotation disk and a second end formed with a practicing ball. Thus, the user can practicing the golf skills indoors by striking the practicing ball. However, the bar is rotated successively when being hit and cannot be returned to the original position automatically, so that the user has to wait until the bar stop moving or exert a force to stop movement of the bar, thereby causing inconvenience to the user.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a golf practicing device having an automatic restoring function.




Another objective of the present invention is to provide a golf practicing device, wherein the energized electromagnet mounted in the housing produces a magnetic force to magnetically attract and move the magnetic block mounted in the cover to return the bar to the original position, so that the bar can be restored to the original position automatically, thereby facilitating the user practicing the golf skill.




In accordance with the present invention, there is provided a golf practicing device, comprising




a housing;




an electromagnet mounted in the housing;




a cover rotatably mounted on the housing;




a magnetic block secured on the cover to rotate therewith and aligning with the electromagnet; and




a bar having an end mounted on the cover for rotating the cover when the bar is hit.




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.

32


and two opposite slide slots


33


each communicating with the opening


32


.




The second barrel


35


of the rotation disk


30


has a first end extended from the second end of the first barrel


31


of the rotation disk


30


and formed with an outer thread


38


. The second barrel


35


of the rotation disk


30


has a periphery formed with two opposite limit grooves


36


.




The cover


10


is rotatably mounted on the housing


20


and secured on the first end of the first barrel


31


of the rotation disk


30


to rotate therewith. The cover


10


has a first side formed with a through hole


11


and a second side formed with a support rod


13


(see FIG.


2


B). A magnetic block


70


is secured on the support rod


13


of the cover


10


and aligning with the electromagnet


71


mounted in the chamber


23


of the housing


20


. The cover


10


has a periphery formed with an oblong slot


12


. The insert


34


of the first barrel


31


is inserted into the through hole


11


of the cover


10


. The second barrel


35


of the rotation disk


30


has a second end protruded outward from the cover


10


. A nut


64


(see

FIG. 4

) is screwed on the outer thread


38


of the second barrel


35


and rested on the cover

and has a first end extended through the oblong slot


12


of the cover


10


and pivotally mounted in the opening


32


of the first barrel


31


. The first end of the bar


50


is formed with a through hole


52


aligning with the two opposite slide slots


33


of the first barrel


31


. A pin


63


is extended through the through hole


52


of the bar


50


and is movably mounted in the two opposite slide slots


33


of the first barrel


31


, so that the first end of the bar


50


is pivotally movable in the first barrel


31


of the rotation disk


30


. The bar


50


has a second end formed with a practicing ball


51


.




In operation, referring to

FIGS. 4 and 4A

with reference to

FIGS. 1-3

, when the practicing ball


41


of the bar


40


is hit, the bar


40


is driven to rotate the cover


10


and the rotation disk


30


, so that the sensing portion


37


of the rotation disk


30


is moved to pass through the sensor


61


as shown in FIG.


3


. When the rotation speed of the rotation disk


30


is reduced, the sensor


61


can detect reduction of the rotation speed of the rotation disk


30


by movement of the sensing portion


37


of the rotation disk


30


, and send a signal to a circuit board (not shown) mounted in the housing


20


to energize the electromagnet


71


mounted in the chamber


23


of the housing


20


, so that the electromagnet


71


produces a magnetic force to magnetically attract and move the magnetic block


70


mounted in the cover


10


so as to return the cover


10


, the rotation disk


30


and the bar


40


to the original position as shown in

FIG. 1

, so that the bar


40


can be restored to the original position automatically, thereby facilitating the user practicing the golf skill.




Accordingly, the energized electromagnet


71


mounted in the housing


20


produces a magnetic force to magnetically attract and move the magnetic block


70


mounted in the covet


10


to return the bar


40


to the original position, so that the bar


40


can be restored to the original position automatically, thereby facilitating the user practicing the golf skill.




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.
