Abstract
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.

in accordance with the preferred embodiment of the present invention comprises a housing
20
, a support plate
40
, a rotation disk
30
, a cover
10
, and a bar
50
.
The housing
20
has an upper portion formed with a recess
21
and a through hole
22
communicating with the recess
21
. The housing
20
has a periphery formed with chamber
23
(see FIG.
2
A). An electromagnet
71
is mounted in the chamber
23
of the housing
20
.
The support plate
40
is secured in the housing
20
and is provided with a bearing seat
41
. A sensor
61
is mounted on the support plate
40
.
The rotation disk
30
is rotatably mounted on the support plate
40
and located in the housing
20
. The rotation disk
30
has a periphery formed with a protruding sensing portion
37
(see
FIG. 2C
) that is movable to pass through the sensor
61
as shown in FIG.
3
.
The rotation disk
30
is provided with a first barrel
31
and a second barrel
35
. The first barrel
31
of the rotation disk
30
has a diameter greater than that of the second barrel
35
. The first barrel
31
of the rotation disk
30
is extended through the through hole
22
of the housing
20
and has a first end rotatably mounted on the bearing seat
41
of the support plate
40
by a bearing
60
and a second end formed with an insert
34
. A bearing
62
is mounted in the recess
21
of the housing
20
and rotatably mounted between the first barrel
31
of the rotation disk
30
and the housing
20
. The first barrel
31
of the rotation disk
30
has a periphery formed with an opening
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
10
to secure the cover
10
on the rotation disk
30
to rotate therewith.
The bar
50
is pivotally mounted on the cover
10
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.
