Description

Device for measuring the slope of ground

The present invention relates to a ground inclination measuring device, and when a user needs to check the inclination of the ground, such as when putting golf, by providing a horizontal display function using a transparent plate load body having a horizontal display element, a simple use operation It relates to a ground inclination measuring instrument configured to measure the ground inclination.

During a golf game, it is sometimes necessary to measure the slope of the ground.

For example, when a golf ball lands on the green during a golf game, the player rolls the golf ball with a putter and puts it into the hole to finally obtain a score. At this time, since the movement path of the golf ball is affected by the slope of the green, the player generally observes the slope of the green through the naked eye and puts in consideration of this.

However, since observing the degree of inclination of the green with the naked eye of the player has a limitation in not providing objective information, prior techniques for improving this have been proposed.

As an example of the prior art, Korean Patent Laid-Open Patent Publication 10-2018-0009731 (published on January 29, 2018) relates to golf glasses having an automatic horizontal display function to improve putting skills, and an automatic horizontal display function to increase the putting success rate Glasses with

However, in the prior art, since the liquid is filled between the two layers of lenses to provide a horizontal line, the manufacturing process of filling the liquid between the lenses is not easy. There was a limitation in that a clear view may not be obtained due to residual viscosity.

As an example of the prior art, Republic of Korea Registered Utility Model 20-0341689 (registered on February 02, 2004) relates to a golf course green slope measuring device, and displays a slope measuring line on a case made of a transparent body, and the angle is made of a transparent body on the case An angle disc with a scale is rotatably built in, a weight for maintaining balance is installed in the lower center of the angle disc, the entrance of the case is covered with a see-through window, and the rotation of the angle disc is controlled on one side of the case A configuration in which a stop member is installed was proposed.

However, the prior art had the inconvenience of having to separately install a weight made of a weight such as lead or metal in the lower center of the angle disk in terms of manufacturing, and for measuring the inclination, the angle made of the inclination measurement line of the case made of a transparent body and the angle made of the transparent body Since the angle scale of the disc is compared with each other, there is a limitation that it is not good to recognize and grasp the angle intuitively.

It is a cross-sectional schematic diagram.

The ground inclination measuring mechanism of this embodiment has a horizontal display function using a transparent plate load body 10 having a horizontal line display element 14 when the user needs to check the inclination of the ground GL, such as when putting golf. By providing , it is configured to measure the ground slope with a simple operation.

To this end, the ground inclination measuring mechanism of the present embodiment includes a transparent plate load body 10 , a left transparent plate 20 , a right transparent plate 30 , and a frame member 40 .

The transparent plate load body 10 includes a transparent plate 16 having a first color and has a horizontal line indicating element 14 . For example, the first color may have any one color tone of a chromatic color such as yellow, red, and blue, or an achromatic color such as gray, but may be a transparent color.

For example, the horizontal line display element 14 of the transparent plate load body 10 is a semicircle diameter line constituting the upper edge of the semicircular transparent plate 16 .

As another example, the horizontal line display element 14 may be formed in the form of a straight line separately printed on the transparent plate load body 10 .

The left transparent plate 20 is a transparent plate having a color different from the first color, and is positioned to face the left side of the transparent plate load body 10 with a gap therebetween. For example, the color different from the first color may be a transparent color of a chromatic or achromatic color tone different from the first color, and preferably may be colorless.

The right transparent plate 30 is a transparent plate having a color different from the first color, and is positioned to face with a gap on the right side of the transparent plate load body 10 . The color of the right transparent plate 30 may be the same as that of the left transparent plate 20 , but is not limited thereto.

The frame member 40 provides a rotatable space in which the transparent plate load body 10 is accommodated therein, and the left transparent plate 20 and the right transparent plate 30 are fixedly coupled to each other. For example, the frame member 40 may be formed of a metal member having a ring shape, and as illustrated in FIG. 4 , the left transparent plate 20 and the right transparent plate 30 are inserted and coupled to each other. It may have coupling grooves 42 and 44 in the form of stepped portions.

The transparent plate load body 10 is rotatably supported by the left transparent plate 20 and the right transparent plate 30 through hinge shafts 12 and 13 provided at one point.

For example, the hinge shafts 12 and 13 are in the form of a left hinge shaft 12 and a right hinge shaft 13 on the left and right sides of one point of the transparent plate 16 of the transparent plate load body 10 , respectively. is formed to protrude.

As an example, the transparent plate load body 10 may be rotated in the R1 or R2 direction of FIG. 9 by its own weight F, and finally maintain a horizontal state.

As such, the ground inclination measuring mechanism of this embodiment does not use a liquid, and is formed to have an asymmetrical plate shape around the positions of the hinge shafts 12 and 13, and the horizontal line display element 14 is horizontal by its own weight. By providing a horizontal line using the transparent plate load body 10, the manufacturing process is simple compared to a structure using a liquid, and even if manufactured thinly, there is no residual viscosity of the liquid, so a clear view can be provided.

In addition, since the ground inclination measuring mechanism of this embodiment does not separately install a metal weight to form its own weight, the manufacturing process is simple, and since the angle is recognized using transparent plates of different colors, the angle is intuitively recognized so it is good to understand

Preferably, the transparent plate 16 of the transparent plate load body 10 has a semicircular shape, and the left hinge shaft 12 and the right The hinge shaft 13 is formed to protrude.

Preferably, the left transparent plate 20 and the right transparent plate 30 each have a circular shape, and the left hinge shaft 12 is inserted into the central point of one side of the left transparent plate 20 in a rotatable state. A left hinge shaft support part 22 is formed, and a right hinge shaft support part 32 into which the right hinge shaft 13 is rotatably inserted is formed at the central point of one side of the right transparent plate 30 . . Preferably, the edges of the left transparent plate 20 and the right transparent plate 30 are colored in a dark color (eg, dark gray, black) to provide clearer visibility when the transparent plate load body 10 is rotated. It is preferred that the portion 33 is formed.

On the other hand, as a modification, the hinge shaft is formed at the center point of the inner surface of the left transparent plate 20 and the right transparent plate 30, respectively, and having a recess at the center point of both sides of the transparent plate load body 10 It is also possible that each hinge shaft support is formed (FIG. 11a). As another example, a through hole is formed at the center point of the left transparent plate 20, the right transparent plate 30, and the transparent plate load body 10, and a hinge structure is formed in such a way that a hinge shaft is inserted into the through hole. may be However, in consideration of the axial end and cross-sectional structure of the hinge shaft as described below, and the ease of assembly, the left hinge shaft 12 on the left side and the right side of the transparent plate 16 of the transparent plate load body 10, respectively. And a configuration in which the right hinge shaft 13 protrudes is preferable.

Preferably, as illustrated in the lower right of FIG. 4 , the left hinge shaft 12 and the right hinge shaft 13 are formed so that the shaft ends 12a and 13a of the hinge shaft have the smallest cross-sectional area. Here, the cross-sectional area may be understood as the cross-sectional area of 13 of FIG. 5 , and the shaft ends 12a and 13a having the smallest cross-sectional area may be understood as, for example, a pointed shape or a slightly rounded, pointed shaft end shape. . In this configuration, while the left hinge shaft 12 and the right hinge shaft 13 are inserted into the left hinge shaft support part 22 and the right hinge shaft support part 32, respectively, the gap between both ends of the hinge shaft is properly maintained and rotated It provides the advantage of reducing the frictional force of the city.

In addition, the left hinge shaft 12 and the right hinge shaft 13 are formed in a cross-sectional shape in which the lower end portion P has the smallest area width w based on the cross section (refer to FIG. 5 ). In this structure, the left hinge shaft 12 and the right hinge shaft 13 are respectively inserted into the left hinge shaft support part 22 and the right hinge shaft support part 32 when the hinge shaft rotates with the hinge shaft support part. It provides the advantage of reducing frictional force. As illustrated in FIG. 5 , the cross-sectional shapes of the left hinge shaft 12 and the right hinge shaft 13 may be variously deformed (eg, asymmetrical pyramidal, inverted triangle, rhombus, pointed oval).

The transparent plate load body 10 of this embodiment provides a rotational force for horizontal maintenance by its own weight without using a separate metal weight, etc., as will be described later, ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate) or In the case of being made of a relatively light synthetic resin material such as acrylic material, if the friction force is strong when the hinge shaft rotates, smooth rotation may not be achieved. In consideration of this point, the transparent plate load body 10 of the present embodiment has the advantage that it can be smoothly rotated and maintained horizontally through the hinge shaft structure that minimizes the frictional force as described above.

Through the configuration as described above, the left hinge shaft support portion 22 formed on the left transparent plate 20 so that the left hinge shaft 12 is inserted in a rotatable state includes a concave portion 22a having a circular cross-sectional shape. and the inlet periphery 22b of the concave portion 22a protrudes toward the transparent plate load body 10 side. In addition, the right hinge shaft supporting part 32 formed on the right transparent plate 30 so that the right hinge shaft 13 is inserted in a rotatable state includes a recessed part 32a having a circular cross-sectional shape, and the recessed part ( The perimeter 32b of the inlet part 32a) is formed to protrude toward the transparent plate load body 10 side. This structure can firmly support the left hinge shaft 12 and the right hinge shaft 13 of the transparent plate load body 10 without increasing the thickness of the left transparent plate 20 and the right transparent plate 30 . makes it possible

Preferably, the recesses 22a and 32a of the left hinge shaft support 22 and the right hinge shaft support 32 have a smaller cross-sectional area from the inlet side (open side) to the end side (closed side), respectively. is formed This structure provides an advantage of reducing frictional force during rotation while properly maintaining a gap between both ends of the hinge shaft and the hinge shaft support.

For example, the transparent plate load body 10 , the left transparent plate 20 and the right transparent plate 30 are formed of any one of Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), or acrylic material. Since this material is suitable for a general synthetic resin material molding method (eg, injection molding), the shape of the detailed structure including the hinge shaft and the hinge shaft support part can be simply implemented, and the weight is light compared to the glass material, so the ground slope of this embodiment It allows the weight of the measuring instrument to be reduced so that it is suitable for portability.

Preferably, at least one of the left transparent plate 20, the right transparent plate 30 and the frame member 40 has an angle display element 34 for recognizing an angle between the horizontal line display element 14 and the ground. is formed For example, the angle display element 34 may be formed in the form of a rotation angle scale about the hinge axis.

6 is a schematic front view showing a modified example of the transparent plate load body of the ground inclination measuring mechanism according to an embodiment of the present invention.

Preferably, the transparent plate load body 10 further includes at least one auxiliary horizontal line display element 14a displayed parallel to the horizontal line display element 14 at a predetermined distance therebetween. As an example, the auxiliary horizontal line display element 14a may be formed by printing or the like.

In addition, the transparent plate load body 10 further has a plurality of horizontal spacing indicating elements 17a or 19 displayed at preset intervals along the horizontal line indicating elements 14 . For example, the horizontal interval indicating elements 17a or 19 may be formed by printing or the like, and may be formed in a line shape 17a or a dot shape 19 .

Preferably, the transparent plate load body 10 further has a vertical line display element 17 passing through the positions of the hinge axes 12 and 13 and perpendicular to the horizontal line indicating element 14 . As an example, the vertical line display element 17 may be formed in a manner such as printing.

As a modification, the transparent plate load body 10 includes an extension portion 10a that is further extended to a position opposite to the semicircular shape with respect to the hinge shafts 12 and 13 .

In this case, the transparent plate load body 10 further includes a vertical line display element 17 that passes through the positions of the hinge axes 12 and 13 and is orthogonal to the horizontal line display element 14, and the vertical line display element (17) is formed to further extend along the extension (10a). The extension portion 10a provides an effect of further extending the vertical line display element 17 above the hinge axis.

Preferably, the transparent plate load body 10 further has at least one auxiliary vertical line display element 17a displayed parallel to the vertical line display element 17 at a predetermined distance therebetween. As an example, the auxiliary vertical line display element 17a may be formed by printing or the like.

The use state of the auxiliary horizontal line display element 14a, the horizontal interval display element 17a or 19, the vertical line display element 17, and the auxiliary vertical line display element 17a will be described later with reference to FIG. 10 .

7 is a front view of a ground inclination measuring device according to another embodiment of the present invention.

Preferably, in at least one of the left transparent plate 20, the right transparent plate 30 and the frame member 40, the horizontal line display element 14 is visually extended to the outside of the transparent plate load body 10 Horizontal extension display elements 34a and 40a for displaying are formed.

As an example, the horizontal extension display elements 34a and 40a may be radially displayed about the hinge axes 12 and 13 as illustrated in FIG. 7 , but as illustrated in FIG. It may be displayed in the form of a plurality of lines arranged in parallel at set intervals.

The use state of the horizontal extension display elements 34a and 40a will be described later with reference to FIG. 10 .

8 is a perspective view of a ground inclination measuring device according to another embodiment of the present invention.

The ground inclination measuring mechanism of the present embodiment further includes horizontal direction generating mechanisms 50 and 52 .

The horizontal direction generating mechanisms 50 and 52 include a wire 52 having one end coupled to one side of the frame member 40 and a handle member 50 coupled to the other end of the wire 52 . can be The handle member 50 may be manufactured in a ring shape to facilitate gripping, but is not limited thereto.

Through the above configuration, the horizontal direction generating mechanisms 50 and 52 generate a suspended state of the frame member 40 so that the user's gripping state does not affect the hinge shafts 12 and 13 in the direction of gravity F and Orthogonal to the horizontal direction.

When the user directly grips the ground inclination measuring device to measure the ground inclination, the inclination in the forward and backward directions may occur unintentionally depending on the gripping state of the user's hand. When the ground inclination measuring mechanism is made to be suspended on the wire 52 using the horizontal direction generating mechanism 50 and 52, there is an advantage in that the ground inclination measuring mechanism is not affected by the gripping state of the user's hand.

For example, the end of the wire 52 may be coupled in a form capable of swinging freely in a manner such as hooking, binding, etc. on the side of the ground inclination measuring device.

9 is a state diagram of the use of the ground inclination measuring mechanism according to the present embodiment. The ground inclination measuring mechanism of this embodiment provides the following basic uses.

By passing through the ground inclination measuring mechanism of this embodiment, when the user looks at the ground (GL) to measure the inclination with the naked eye, the horizontal line 14 and the ground (GL) recognized through the horizontal line display element 14 An angular difference with respect to the angle may be measured, and this difference may be measured as an inclination angle value of the ground GL with respect to the horizontal line.

In this case, the user may recognize the angle between the horizontal display element 14 and the ground GL in the form of a specific numerical value through the angle display element 34 .

10 is a view showing various uses of the ground inclination measuring device according to the present embodiment. The ground inclination measuring device of the present embodiment can be used for various purposes as follows.

(a) Side view of the golf ball (B) and the hole cup (H) on the green (to determine the height and slope)

After placing the golf ball (B) on the green and going to the green, the user visually observes the hole cup (H) and the golf ball (B) through the ground inclination measuring mechanism of this embodiment in the direction in which they are seen side by side. If the height is determined at a certain distance and height based on the hole cup (H) and the golf ball (B), it is possible to determine whether the slope is uphill or downhill from the golf ball (B) to the hole cup (H). .

For example, when the hole cup (H) and the golf ball (B) are viewed from a certain distance and a certain height with the ground inclination measuring device of this embodiment, the hole cup (H) is based on the auxiliary horizontal line display element (14a) rather than the golf ball (B) is about 1 and a half square above, and the distance between the two is about 6 and a half squares (distance about 13 meters) based on the horizontal spacing indicator element 19, and the uphill slope is about one and a half square feet, so the user (golfer) pushes 3 meters harder. You can putt. How much harder to putt can be determined based on the subjective putting strength of each user grasped while using the ground inclination measuring device of the present embodiment for each situation.

(b) Checking the left and right inclination without using the plum bobbing method using the putter

The plum bobbing method is a technique in which the user holds the grip of the putter with one hand and drops it vertically to connect the golf ball (B) and the hole cup (H), then sets the shaft at eye level and reads the slope of the green through this. When using the plum bobbing method, it is necessary to hold the putter in an exact vertical position, but when the wind blows, the verticality is not well realized and it is difficult to check whether the putter itself is vertical. It also requires a lot of practice, such as not moving while the user is looking at the putter. However, since the ground inclination measuring device of this embodiment does not use a putter, it is not affected by the wind and the vertical is implemented directly, so it does not take long and can be easily viewed.

Place the golf ball (B) and the hole cup (H) on a straight line and set the vertical line display element 17 of the ground inclination measuring mechanism of the embodiment viewed from behind the golf ball (B) so that the golf ball (B) and the hole cup (H) match The left and right inclinations may be compared by comparing the heights of the left and right portions (eg, slightly different colored grass, long grass, fallen leaves, etc.) on the rear auxiliary horizontal line display element 14a.

In the case of (b), since the fallen leaves (L) on the left are slightly higher than the long grass (G) on a similar line, it is understood that the left side is slightly higher.

(c) Check whether the golf ball (B) is correctly positioned after determining the slope of the green

After determining the slope of the green, the direction line (BL) marked on the golf ball (B) is placed in the desired direction based on the hole cup (H) (eg, shifted by two cups to the left of the hole cup (H)). It may not be easy to accurately check whether the direction line BL of (B) is pointing to a desired place. At this time, in a state in which the transparent plate load body 10 is not rotated by tilting the ground inclination measuring device of this embodiment slightly forward or backward, the vertical line display element 17 is aligned with the direction line BL marked on the golf ball B If you look at the hole cup (H) after making this, you can grasp the positional relationship between the hole cup (H) and the direction line (BL).

For example, after grasping the green slope, the golf ball (B) was directed toward the direction line (BL) of the golf ball (B) with the aim of shifting the golf ball (B) by two cups to the left of the hole cup (H). When the vertical line display element 17 of the inclination measuring device coincides with the direction line BL of the golf ball B, if it is about a cup and a half to the left, the direction line BL of the golf ball B is half If you move the cup further to the left, it can be the direction you were aiming for at the beginning (the direction you shifted by two cups).

(d) Display the horizontal extension display elements 34a and 40a at regular intervals on the border to match the horizontal display elements 14 of the transparent plate load body 10

If the distance between the golf ball (B) and the hole cup (H) is long, in order to place the golf ball (B) and the hole cup (H) together within the field of view penetrating the ground inclination measuring device of this embodiment, it must be viewed from a greater distance than usual. But this may not be easy. At this time, any one of the golf ball (B) or the hole cup (H) is located outside the field of view passing through the ground inclination measuring mechanism of this embodiment, in this case, the horizontal extension display elements 34a and 40a and the transparent plate load body 10 ) by matching the horizontal line indicating element 14 or the auxiliary horizontal line indicating element 14a to help determine the height even if either the golf ball (B) or the hole cup (H) is outside the field of view passing through the ground inclination measuring device can be obtained

For example, when the hole cup H is positioned at the left end of the field of view passing through the ground inclination measuring device, the golf ball B is positioned outside the field of view passing through the ground inclination measuring device, but the horizontal extension indicator element 34a , 40a) and the horizontal display element 14 or the auxiliary horizontal display element 14a of the transparent plate load body 10 can be matched to determine the approximate height of the golf ball (B).

The horizontal extension display elements 34a and 40a may be radially displayed about the hinge axes 12 and 13 as illustrated in FIG. 7 , but for the function of the present embodiment, as illustrated in FIG. 10(d) It may be displayed in the form of a plurality of lines arranged in parallel at a preset interval.
