TECHNICAL FIELD

The present invention relates to a multipurpose putting practice device for enabling straight putting and distance practice by situation, and more particularly, to a multipurpose putting practice device for enabling straight putting and distance practice by situation through which a putting practice for a short distance or medium and long distance may be performed in environments having flat, uphill, and downhill lies, a golf ball may be collected at the same place when putting is performed through a putting line formed to protrude in an upward direction, directivity may be improved for running the golf ball up to a target point in a constant direction by determining a hole-out state of the golf ball using sound and visual identification, a correct putting posture is formed, and a distance control practice at a desired field may be performed by quantifying and visualizing the result of the putting so that a plurality of green speeds are compared with each other and experienced.

BACKGROUND ART

Generally, since a golf putting practice is difficult on an ordinary day because golf courses are mainly located at suburbs, putting practice is simply performed indoors or outdoors on the ordinary day through a putting practice device which is separately manufactured.

Such a conventional putting practice device includes a mat, which is similar to green, disposed on a body having a predetermined shape, and a hole formed in the middle of a rear area of the body so that a user performs the putting practice toward the hole at a putting position of a front area of the body.

However, since the conventional putting practice device is formed in a plate shape, there are some problems in which a practice for directivity cannot be performed by putting, a bad habit on a moving direction of a golf ball can occur according to a failure of a levelness state of a mat or bottom surface, and a putting practice for uphill and downhill lies is also difficult, and thus skills used in the practice cannot be demonstrated in an actual field.

In addition, a practice of putting a golf ball toward a hole cup for a medium and long distance is difficult when the putting practice is performed indoors, and there is a problem in which a success rate of putting is very low in the actual field because golf courses each have different lies and speeds of greens.

Further, a practice can be performed using a putting mat in the case of amateurs. However, there is a problem in which golfers having a long experience or professionals are not using a general putting mat.

A putting practice device for enabling a putting practice by integrating lies of actual fields and a plurality of green speeds in consideration of the above problems has been developed by inventors for this present invention.

MODES OF THE INVENTION

A multipurpose putting practice device100for enabling straight putting and distance practice by situation according to an embodiment of the present invention will be described with reference toFIGS. 1 to 11. First, as shown inFIGS. 1 to 3, in the embodiment of the present invention, a body102for putting a ball, which has been placed on a bottom surface thereof, in a longitudinal direction is formed.

The body102may be formed with two or more bodies that may be coupled to each other. A departure preventer104is installed on an upper surface of a rear portion of the body102so that a ball600does not depart.

A level determiner106is preferably installed in a rear portion of the departure preventer104for adjusting a level of the body102.

The level determiner106is a general leveler15, and is preferably installed to be accommodated in a receiving groove18.

Further, a vertical body leveler19is preferably installed for a level determination of a vertical body putting line42to be described below.

Level controllers107are preferably installed under the bottom surface of the body102, and a plurality of lie controllers108are installed thereunder.

The level controllers107are respectively and preferably installed in upper portions of the lie controllers108and fixedly coupled with the body102.

Two level controllers107are preferably installed under each of a front portion and a rear portion of the bottom surface of the body102. In each of the level controllers107, a male screw portion is formed so that a level is adjusted by laterally rotating to control a height, and an insertion groove is formed in a lower portion thereof.

The lie controllers108preferably control lies of the front and rear of the bottom surface of the body102by lifting the body102after lifting bodies22are inserted into and coupled with lower portions of the level controllers107under the bottom of the body102. That is, it is preferable that a lie control of the body102be performable by lifting the front of the body102or lifting the rear of the body102.

Here, the lifting body22is provided with a plurality of lumped masses having a predetermined height for implementing a lie angle of the body102which are stackable.

In addition, a connector200is preferably and connectedly installed on the body102in a forward direction, and more preferably, on a front end of the body102in a moving direction of the ball600after putting is performed.

The connector200is inserted into, coupled with, and installed on a lower end portion of the body102.

Here, the connector200is formed with a connector body28that has a circular arc shape in cross section, a gentle lie, and an upper end that is inserted into, coupled to, and installed on a vertical body300to be described below.

Since the vertical body300is inserted into, coupled with, and installed on the upper end of the connector200, the vertical body300prevents an excessive departure of the ball600in an upward direction after putting is performed, and is preferable so that a putting practice may be performed according to a distance desired by a user after a determination of a distance measured when the putting practice is performed. That is, it is preferable to form distance indication gradations44and46so that putting practices for flat, uphill, and downhill lies are performable based on a green speed.

A vertical departure preventer114is provided in a center portion of the vertical body300, and is preferably coupled to the vertical body300as an integrated part.

A soft impact preventer74is inserted into the vertical departure preventer114to prevent excessive departure of the ball600in the upward direction when a putting practice is performed.

At the same time, vertical body distance indicators116and118, which are formed so that a practice may be performed according to a distance and a lie that are desired for the practice when putting is performed are respectively installed on lateral side surfaces of the vertical body300. That is, the vertical body distance indicator116is formed on a right side surface of the vertical body300, and the vertical body distance indicator118is formed on a left side surface thereof.

Here, the vertical body distance indicators116and118preferably display putting distance indications for flat, uphill, and downhill lies based on a green speed so that skills of professionals in addition to general users may be improved by a practice.

In addition, a hole-out determiner120having a hole-out determination bell62is preferably installed above the vertical body300and the connector200.

The hole-out determiner120is installed so that the ball600hits and passes through the hole-out determination bell62and makes a sound or is visually identified after putting is performed.

Further, the hole-out determiner120may include a gradation determination window56which may determine distances of the vertical body distance indicators116and118and connector distance indicators122and124.

Artificial turf or a carpet mat is preferably attached and installed on one side of the body102, the connector200, and the vertical body300, which are described above.

Subsequently, the multipurpose putting practice device100for enabling straight putting and distance practice by situation according to the embodiment of the present invention will be described in more detail. First, a bottom body10is formed extending along the bottom surface of the body102to be long, and a putting line12, which extends in a longitudinal direction to be long and has a predetermined width so that the ball600runs on a straight line, protrudes from and is formed in the center portion of the bottom body10.

Since the putting line12protrudes in an upward direction more than the bottom body10, when the ball600runs out of a straight line after putting is performed, the ball600runs to a left or right side of the putting line12.

Sidewalls14are respectively formed on both lateral sides of the bottom body10.

When the ball600runs out of the putting line12, the sidewalls14serve to prevent a departure of the ball600to the outside of the bottom body10.

Using the putting line12, a golf ball may run to a target point in a constant direction when a putting practice is performed, and thus a putting ability can be improved.

Since the departure preventer104is installed in a rear portion of the bottom body10of the body102to prevent a departure of the ball600to the rear portion of the bottom body10when the ball600runs and returns, the departure preventer104is formed with two rectangular departure preventer bodies16, and the entire departure preventer bodies16are obliquely formed.

When a height of the departure preventer104is slightly greater than that of the putting line12, it serves to prevent a departure of the ball600which returns through the connector200after putting is performed and to easily place the ball600on the putting line12.

In addition, a body leveler15for adjusting a level of the putting line12of the body102is preferably installed in the rear portion of the departure preventer104.

That is, the body leveler15installed on the body102and the vertical body leveler19to be described below serve to adjust the level of the putting line12, a connector putting line30, and the vertical body putting line42.

Meanwhile, since the plurality of lie controllers108are installed on a lower surface of the body102for achieving a match of a lie with a green lie by a lifting control of each of the front and rear portions of the body102, the lie controllers108and level controllers107fixedly installed under the bottom surface of the body102are provided in insertion grooves having cylindrical shapes with a plurality of lumped masses, which are stackable, having a predetermined height for implementing a lie angle of the body102.

The level controller107is formed with a fixed body20formed in a cylindrical shape and having a bolt portion in an upward direction, and a lifting body22coupled with a lower portion of the fixed body20and formed so that a vertically height control may be performed.

When a lie is formed right downward by lifting the front portion of the body102by coupling the lifting bodies22to lower portions of the level controllers107, the lie controllers108installed under the front portion of the body102installed as described above make an uphill lie needed for putting. When the lie is formed left downward by lifting the rear portion of the body102by coupling the lifting bodies22to the fixed bodies20, the lie controllers108under the rear portion of the body102make a downhill lie.

Fronts and rears of the lifting bodies22are coupled with or separated from the level controllers107or the fixed bodies20, and thus a height is freely controlled and lies of the front and rear of the body102are controlled. Thereby, the lie controllers108make a lie similar to a green lie.

As described above, the lie controllers108are preferably installed so as to control a height of the body102to take the same effect as that generated by a practice performed on an uphill or downhill lie of an actual field.

The multipurpose putting practice device100for enabling the straight putting and distance practice by situation according to the embodiment of the present invention installed as described above, as shown inFIGS. 2 and 3, is installed so that the body102, connector200, and vertical body300are connected to each other. Here, the connector200may include the connector putting line30connected to the putting line12of the body102, and the vertical body300may include the vertical body putting line42connected to the connector putting line30.

The hole-out determiner120is installed and located at the center portion of the vertical body putting line42of the vertical body300connected to the connector putting line30of the connector200.

That is, when the ball600runs along the putting line12and reaches the connector putting line30or the vertical body putting line42while the putting practice is performed, the hole-out determination bell62is preferable installed to generate a sound when the ball hits it.

FIG. 4is a perspective view illustrating a structure of the connector of the embodiment of the present invention. The connector200is formed with a connector body28having a side cross section in a circular arc shape, and a connector putting line30is formed to protrude in an upward direction in a center portion of the connector body28.

The connector putting line30is preferably formed to connect with the putting line12of the body102.

Subsequently, connector sidewalls32and34are respectively formed on lateral sides of the connector body28.

Connector distance indicators122and124are respectively formed on the connector sidewalls32and34, and connector distance indicating gradations76and78may be respectively formed on inner and outer surfaces of the connector body28.

A lower insertion portion36is formed in the center lower portion of the connector body28.

The lower insertion portion36is inserted into, coupled with, and installed in the rear portion of the body102, on which the ball600runs, and is preferably coupled therewith and installed therein so that the connector putting line30is aligned with the putting line12.

In addition, an upper insertion portion38is formed in the center upper portion of the connector body28.

The upper insertion portion38is preferably inserted into and installed in a lower end portion of the vertical body300to be aligned with the vertical body putting line42of the vertical body300.

FIG. 5is a perspective view illustrating a structure of the vertical body according to the embodiment of the present invention, and the body102and the connector200are connected in an upward direction. The vertical body300is formed with a rectangular body40, a vertical body putting line42is formed to protrude from the center portion thereof, a vertical departure preventer114is formed in an upper portion of the vertical body putting line42, and vertical body distance indicators116and118are respectively formed on lateral sides of the body40of the vertical body300.

Distance indicating gradations44and46are respectively formed on inner and outer side surfaces of each of the vertical body distance indicators116and118.

That is, lie indicators66by green speeds (ft), which may be used for both amateurs and professionals in field environments having different green speeds, are formed on the vertical body distance indicators116and118.

Here, vertical body distance indicating gradations44and46and connector distance indicating gradations76and78are displayed on the lie indicator66by green speeds (ft), and a type having a flat distance gradation70, and a downhill distance gradation68and an uphill distance gradation72by a predetermined angle unit may also be displayed thereon.

The vertical departure preventer114is coupled with and installed on an upper end side of the body40of the vertical body300so that the ball600does not depart. The vertical departure preventer114is formed as an integrated part, and an upper departure partition48coupled in a downward direction from an upper end of the vertical body300is formed in a lateral direction.

An insertion coupler50is formed in a lower portion of the upper departure partition48to insert into the vertical body300.

A departure of the ball600from the vertical body300is preferably prevented by forming the upper departure partition48protruding in a forward direction of the vertical body300so that the ball600does not depart in an upward direction. That is, the vertical body300is formed to have slope having a predetermined departure preventing angle A, and the departure preventing angle A is preferable in a range of 100 degree to 130 degree. When the ball runs upwardly along a putting line, the ball hits a soft impact preventer26which absorbs an impact, and then the ball returns downwardly so that the departure of the ball is prevented.

Meanwhile, the connector distance indicator122and124and the vertical body distance indicators116and118, which are quantified and visualized green speeds, may be displayed as green speeds by courses (4.5 ft to 10.5 ft) that are the announced green speeds of golf courses measured by Stimpmeter, which is a formal green speed gauge of United States Golf Association (USGA).

Like this, Stimpmeter, the green speed gauge, is used to measure green speeds by courses on green turf, artificial turf, or a carpet mat for measuring the green speeds. That is, when Stimpmeter, i.e., the gauge, is installed on the green turf, the artificial turf, or the carpet mat on which the green speeds by courses are measured, and the gauge for measuring gradation and supporting the golf ball at a height of specific location is lifted upward, the ball600freely falls along a lie and then a run distance by a meter (M) unit may be measured. After the measured value is separately recorded for each of the green speeds by courses, measurements are performed several times at a height at which the measured value is recorded using the multipurpose putting practice device100for enabling the straight putting and distance practice by situation. Then, distances by different green speeds (ft) according to a flat level and lies are classified for amateurs and professional, and may be displayed on the connector distance indicators122and124and the vertical body distance indicators116and118in various types such as stickers, prints, etc.

Like this, a sensitivity of existing green speeds is experienced through the displayed connector distance indicators122and124, the vertical body distance indicators116and118, and the hole-out determiner120, and putting practices are performed with a determination of green states according to the lies and distances, and thus professionals in addition to amateurs can practice usefully.

Since the hole-out determiner120is for determining whether the ball600is entered into a hole cup or not when a putting practice is performed, as shown inFIG. 6, clamps121are symmetrically formed in both directions to be fixedly inserted into the connector distance indicators122and124and the vertical body distance indicators116and118of the body40of the vertical body300.

Gradation determination windows56are respectively formed in the clamps121so that the distance indicating gradations76,78,44, and46of the connector distance indicators122and124and the vertical body distance indicators116and118are displayed.

In more detail, the clamp121includes a rectangular clamp body52and a gradation determination body54, and the gradation determination windows56are formed on one side surfaces of the clamp body52and the gradation determination body54, and preferably, formed to display the distance indicating gradations44and46of the vertical body distance indicators116and118.

A rotatable hinge part123is preferably provided to the clamp121.

The rotatable hinge part123is formed with a rotatable fixed protrusion64and a fixed protrusion60rotatably inserted into the rotatable fixed protrusion64.

The distance indicating gradations44,46,76, and78are preferably determined through the gradation determination windows56.

A holder58, which extends and is bent in a-shape, is connectedly installed above the clamp body52, and the rotatable fixed protrusion64is formed in a center portion of the holder58.

The rotatable fixed protrusion64is formed in a-shape, and is preferably coupled with and installed on the hole-out determination bell62to be rotatable.

Since the hole-out determination bell62is installed on the rotatable fixed protrusion64to be rotatable, the fixed protrusion60is formed in an upper portion of the hole-out determination bell62and coupled to the rotatable fixed protrusion64formed on an end of the holder58, and the fixed protrusion60is rotatable based on the holder58. That is, since the fixed protrusion60of the hole-out determination bell62is coupled and installed, when the ball600runs and touches the hole-out determination bell62after putting is performed, the hole-out determination bell62makes a sound and rotates about the rotatable fixed protrusion64of the holder58.

Here, as shown inFIGS. 8A and 8B, when the hole-out determination bell62rotates at a constant rotation angle a, the ball600does not pass through and is entered into a hole cup, and when the hole-out determination bell62rotates at a predetermined rotation angle b or more, or fully rotates a full rotation or more, the ball600passes through the hole cup and may be determined as not hole-out.

Subsequently,FIGS. 7A and 7Bare views illustrating the distance indicating gradations44,46,76and78of the connector distance indicators122and124and the vertical body distance indicators116and118according to the embodiment of the present invention, and lie indicators66by green speeds (ft) are respectively formed on left and right side surfaces of the vertical body distance indicator116and118, i.e., outer and inner surfaces thereof.

In more detail, the distance indicating gradations44,46,76, and78of the lie indicators66by green speeds (ft) are displayed as flat distance gradations70, and downhill distance gradations68and uphill distance gradations72by predetermined angles.

Meanwhile, artificial turf or a carpet mat is preferably mounted on the putting line111and the bottom surface110of the body102, and thus an environment similar to an actual field may be provided.

Further, separate departure preventing protrusions150are preferably mounted on both ends of the bottom surface110of the putting line111of the body102, on which a putting practice is performed, so that a departure of a golf ball, which returns through the connector200after putting is performed, is prevented.

A connector200is additionally provided on an end of the body102in a longitudinal direction, and thus a golf ball may be collected when a putting practice is performed.

As shown inFIGS. 12 to 15, the connector200includes a bottom surface210, sidewalls220are formed on both ends of the bottom surface210to prevent a departure of a golf ball to the outside, and a curved shape extending in an upward direction is preferably formed on an end of the bottom surface210corresponding to the front thereof, and thus when the golf ball hit on the body102reaches the connector200after putting is performed, the golf ball runs along the curved shape in an upward direction to collect position energy, then the position energy is converted into kinetic energy while the golf ball runs in a downward direction, and thus the golf ball runs to the body102.

Meanwhile, a connector distance indicator213, in which a plurality of green speeds are quantified, visualized and displayed, is preferably mounted on the connector sidewall220.

The plurality of green speeds of the connector distance indicator213are green speeds by courses (4.5 ft to 10.5 ft) that are the announced green speeds of golf courses measured by Stimpmeter, which is a formal green speed gauge of USGA.

Like this, Stimpmeter, which is a green speed gauge, is used to measure the green speeds by courses on green turf, artificial turf, or a carpet mat.

Further, on the green turf, the artificial turf, or the carpet mat on which the green speeds by courses are measured, as shown inFIG. 17, when a gradation measuring gauge700supporting a golf ball is lifted upward at a height of specific location of a distance gauge500on which a distance indicating gradation530is mounted, the ball600freely falls along a lie of the distance gauge500and a measured value of the distance gauge500, which is a run distance by meter (M) units, is separately recorded for each green speed by course.

Further, in the distance gauge500, the gold ball runs on the putting practice device from a height of the measured value of the distance indicating gradation530separately recorded for each of the green speeds by courses, and positions by meters (M) are obtained. The connector distance indicator213, which displays the positions by meters (M), is preferably mounted on connector sidewalls in a sticker type.

Like this, conventionally, a green speed is checked based on sensitivity, but the putting practice device is able to check the quantified green speeds by courses and to perform a practice.

The clamp (or the press type holder) may variously move in vertical and lateral directions and be fixed at a desired position.

Here, a height of a steel wire above the bottom surface is set so that an upper portion of a golf ball is not in contact with the steel wire, the circular steel wire is embedded in a bell ring so that energy generated by a straight run of the golf ball is transferred to the bell and converted into rotation energy through the circular steel wire after putting is performed, when the putting is performed with a stronger force than that required for a target distance, impact energy makes a rotation of the bell through the circular steel wire and this is helpful for a distance control practice due to being directly determinable by eye, and it is preferable to fix the bell by capping or welding so that the bell does not depart from an end of the wire by the impact.

Meanwhile, when the golf ball runs from the putting line111of the body to the vertical body putting line311through the connector200, since a position of the bell of the vertical body is moved by a radius distance of the bell from the putting line by gravity, a holder in a clamp type may be preferably interlinked with and fixed on the sidewalls in consideration of the moving distance.

Further, after an arrow or the like is marked in the center of the clamp, the movable hole cup bell400is preferably set to a target distance of the connector distance indicator213and the vertical body distance indicator313.
