Embodiment

As shown in FIGS. 1 to 5, the putting exerciser 10 according to one embodiment of the present invention includes a movable ball case 100 provided therein with a plurality of metal balls B having a weight, and a rail structure 200 on which the metal balls B are movably mounted.
The movable ball case 100 includes a plurality of cases C spaced apart from each other at a predetermined interval for partially covering upper surfaces of the metal balls B.
Therefore, when a putting club P of a user hits the case C, the metal ball B inside the case C rotates to allow the movable ball case 100 to move on the rail structure 200.
Since the metal ball B has a heavy weight, physical strength required for putting can be enhanced when the user continues to hit the movable ball case 100 of the present invention by the putting club.
The case C may have various shapes for mounting the metal ball B therein as described above, but as shown in the drawings, the case C may include an upper case 120 for covering an upper portion of the metal ball B, and a lower case 110 coupled to a bottom surface of the upper case 120 and provided therein with the metal ball B.
In addition, a connection part 130 is disposed between lower cases 110 to connect the lower cases 110.
In other words, the upper case 120 of the present invention is disposed on the upper surface of the metal ball B, the lower case 110 is installed on a lower surface of the upper case 120, and as a result, the metal ball B is disposed inside the case C.
When the putting club P of the user hits the case C in a state that the upper surface of the metal ball B partially makes contact with an inner upper side surface of the upper case 120, the metal ball B is rotated inside the case C, and accordingly, the case C is moved in the hitting direction.
As shown in the drawings, the upper case 120 may include an upper case body 121 for covering the upper surface of the metal ball B, and a recess 122 recessed in an inner side surface of the upper case body 121.
In addition, the lower case 110 may include a lower case body 111 inserted into a lower inner side surface of the upper case body 121 and having a hollow structure, in which upper and lower surfaces of the lower case body 111 are open.
When the metal ball B is inserted inside the lower case body 111, a lower portion of the metal ball B is partially exposed as shown in the drawings. The exposed portion of the metal ball B makes contact with the rail structure 200 to be described below while the metal ball B is rotated, and accordingly, the movable ball case 100 of the present invention is moved.
Meanwhile, a protruding sill 112 protrudes from an outer side surface of the lower case body 111 and is inserted into the recess 122.
In other words, the lower case body 111 is inserted into the inner side surface of the upper case body 121 while the protruding sill 112 is inserted into the recess 122, and as a result, the lower case body 111 is engaged to the inside of the upper case body 121.
The protruding sill 112 is inserted into the recess 122 as described above for the purpose of fixing the lower case body 111 to the inner surface of the upper case body 121. Thus, it is within the scope of the present invention even when the protruding sill 112 and the recess 122 have different shapes if the above purpose can be achieved.
The upper case 120 of the case C may have a semi-spherical upper case body 121 as shown in FIGS. 1 to 4, or a cam member 123 protruding in a horizontal direction from the upper case body 121 as shown in FIGS. 5 and 6.
When the upper case body 121 of the present invention as described above is rotated, a position of the cam member 123 is changed, so that the distance between the upper cases 120 can be adjusted corresponding to the thickness of the putting club even if the thickness is changed.
In other words, when cam members 123 are arranged to face each other as shown in FIG. 5, the distance between the cam members 123 is narrowed, so that a putting club having a relatively thin thickness can be used.
If a thicker putting club is desired to be used, the position of the cam member 123 can be changed by rotating the upper case body 121. For example, when the cam member 123 of the upper case body 121 on a left side of the drawing is disposed to face the left side as shown in FIG. 6, the distance between the upper case bodies 121 is widened, so that the thicker putting club can be used.
In addition, although two cases C may be provided as shown in the drawings, this is an example for explaining the present invention, so the present invention is not limited thereto, thus a plurality of cases C, for example, at least three cases C may be provided.
The connection part 130 is disposed between the lower cases 110 as described above, and to this end, as shown in the drawings, the connection part 130 may include a plate-shape connection plate 131, and a plurality of protruding ribs 132 protruding from the connection plate 131 and arranged in an extension direction of the connection plate 131.
In other words, the connection plate 131 connects the cases C and the protruding ribs 132 may improve the strength of the connection plate 131.
Accordingly, even if the putting club P of the user hits the case C, the connection plate 130 can be prevented from being damaged.
The case 100 of the present invention as described above can be hit by the putting club, and the rail structure 200 on which the metal balls B disposed inside the case 100 are movably mounted will be described with reference to FIGS. 7 to 9.
The rail structure 200 may include a rail part 220 having a groove U for mounting the metal ball B therein, and a footrest 210 disposed at one side of the rail part 220.
In other words, when the user hits the case C by the putting club P in a state of being positioned on the footrest 210, the metal ball B is rotated in a state of being disposed on the groove U, and accordingly, the case C is moved.
Therefore, physical strength required for putting can be enhanced when the user continuously hits the metal ball B having the weight by the present invention as described above.
Meanwhile, the rail part 220 may include a rail body 221 having a U-shape groove U making contact with a part of the metal ball B as described above.
In addition, the groove U may make contact with a specific point of the metal ball B as shown in the drawings for allowing the metal ball B to move.
In other words, it is within the scope of the present invention if the grooves U have a shape allowing the metal ball B to be mounted on the grooves U such that the metal ball B can move along a predetermined path without deviating to the outside.
In addition, the rail part 220 may include a rail body 221 having a U-shape groove U making contact with a part of the metal ball B, a footrest fastening part 223 recessed on one side surface of the rail body 221 such that the footrest 210 is inserted into the footrest fastening part 223, and a cover member 222 installed on both side ends of the rail body 221.
In other words, since the footrest 210 is to be installed on the rail part 220, the fastening part 223 is recessed on one side surface of the rail body 221, that is, a side surface of the rail body 221 in the thickness direction, and the footrest 210 is inserted and installed into the footrest fastening part 223.
The cover member 222 is installed on both longitudinal side ends of the rail body 221, and may have various shapes, such as a flat shape having no recess portion on the surface thereof as shown in the drawings.
The footrest 210 is provided to allow the user to step on as described above, and may include a footrest body 211.
The footrest body 211 may generally have a plate shape, but the present invention is not limited thereto, and it is within the scope of the present invention even when footrest bodies 211 have different shapes if the footrest bodies 211 have a shape that can be stepped on by the user.
In addition, a foot mark part 212 may be provided on the footrest body 211 for marking a position for feet of the user.
In addition, a putting distance display part 213 may be displayed on one side of the rail body 221 for indicating a distance.
In other words, the foot mark part 212 may indicate a user position appropriate for the putting, and the user may measure a movement distance by the putting distance display part 213 which can indicate the movement distance of the case C.
Meanwhile, the putting distance display part 213 may have various configurations including a scale as shown in the drawings if the putting distance display part 213 can indicate the movement distance.
Of course, the movement distance can be indicated by a sensor which detects a current position of the case C and a stopped position of the case C after movement.
To this end, the sensor may include an infrared sensor for recognizing an object and a control unit for receiving a signal from the sensor to analyze and display the signal.
Hereinafter, a method for enhancing physical strength by using the putting exerciser 10 of the present invention will be described with reference to FIGS. 1 to 5 again.
First, a putting club P is disposed between the cases C in a state that a user is positioned on the foot mark part 212 of the footrest body 211.
In addition, the putting club P is disposed on an upper portion of the connection part 130.
In this state, the movable ball case 100 is moved by hitting the lower case 110 or the upper case 120 with the putting club P.
The metal ball B is rotated inside the upper case 120 and the lower case 110, while one lower portion of the metal ball B is exposed to move on the groove U of the rail body 221 as described above.
Since the user hits and moves the case C provided therein with the metal ball B having the weight by the present invention as described above, the physical strength of the user that is required for the putting can be enhanced.
As described above, the space between upper cases 120 can be adjusted according to the thickness of the putting club P by changing the position of the cam member 123 through rotating the upper case body 121 of the upper case 120.
In addition, the case C can be hit by the putting club P after forming the groove U of the rail body 221 to have a specific depth L such that the case C is inclined at a specific angle θ.
To this end, the depth L of the groove U of the rail part 220 is set to ¼ of the metal ball B so as to slantingly arrange the metal ball B, so that the case C is entirely inclined.
In this state, if the case is hit by the putting club, various putting slopes can be implemented.
Meanwhile, when the case C is moved by the putting club P of the user, the movement distance of the movable ball case 100 can be measured by the putting distance display part 213.
In other words, the putting distance display part 213 is displayed on the footrest body 211 and disposed on one side of the rail body 221.
Therefore, the movement distance of the case C can be easily measured by the putting distance display part 213.
The present invention is described in detail through specific embodiments, which is provided for explaining the present invention specifically, but the present invention is not limited thereto, and it is apparent that variations and modifications can be made by those skilled in the art within the technical ideas of the invention.
Simple variations and changes of the present invention may fall within the scope of the present invention, and the specific scope of the present invention will be clarified by the appended claims.
