Description

  The present invention relates to a marker for golf balls, for example.

  Various markers have been proposed to mark this position when the ball is positioned on the green in golf.

  For example, as shown in FIG. 6, a space portion is formed in the marker body so that the small sphere can roll freely, and the inclination direction and the inclination of the marker body are determined by the stationary position of the small sphere on the sphere rolling surface of the space portion. A golf ball marker showing a degree has been proposed (Japanese Patent Laid-Open No. 2001-286590).

  Further, as shown in FIG. 7, a flat plate portion, a shaft portion suspended from the flat plate portion, and a fitting hole that is located on the opposite shaft side of the flat plate portion and into which the tip of the shaft portion can be fitted. Has been proposed (Japanese Patent Application Laid-Open No. 2003-305144).

  Further, a magnetic ball marker has been proposed (Japanese Patent Laid-Open No. 2004-357925).

  In addition, as shown in FIG. 8, in the golf ball marker comprising a base portion that is substantially flush with the green surface, and an embedded portion that hangs from the lower surface side of the base portion and can be embedded in the green surface, There has been proposed a golf ball marker (Japanese Patent No. 312249) characterized in that an upper portion of the base portion is provided with an upright portion that can stand up with respect to the base portion.

Further, as shown in FIG. 9, a disk-shaped base portion formed of a metal material that is substantially flush with the green surface, and the base portion are formed separately from each other and are formed on the upper surface side of the base portion. A disc-like standing portion formed from a metal material that can stand up from a green surface, and the standing portion is connected to the base portion via a hinge portion and covers the base portion A marker for a golf ball that is rotatable between a standing position raised from the base portion and the base portion, wherein one of the base portion and the standing portion is slightly larger than the other. In addition, a golf ball marker is proposed (Japanese Patent No. 3118222) characterized in that a concave portion is provided that can accommodate the other when the upright portion is in the closed position. .
JP2001-286590 JP 2003-305144 A JP 2004-357925 A Japanese Patent No. 3101249 Japanese Patent No. 3118222

  The markers in Patent Documents 1, 2, and 4 have axes A, B, and C that are embedded in the green surface, as can be seen from the corresponding drawings. That is, a flat plate and axes A, B, and C perpendicular to the flat plate are provided.

  By the way, this type of marker is used in golf. Therefore, it is often put in, for example, a pocket.

  However, it is very troublesome to play golf with such a three-dimensional marker in a pocket. Moreover, even if it is held in something with a magnet, for example, without being put in the pocket, the protruding portions of the axes A, B, and C are still troublesome. Therefore, it cannot be said that it is preferable.

  On the other hand, unlike the markers such as Patent Documents 1, 2, and 4, the marker of Patent Document 5 does not have an axis. Therefore, holding is very easy.

  However, it has been found that the marker as in Patent Document 5 has the following problems.

  First, the inverted solid D opens at an open angle of 90 ° or more. For example, if it is opened at an angle of 100 °, the center of gravity does not exist on the base body E but is at an off position, which is very unstable. In particular, since green is a lawn, this type of marker is easy to repeat. Golf is played even when the wind is strong. In such a case, even when the open angle of the inverted solid D is 90 ° or less, for example, 60 °, the wind blows on the inverted solid D, so that the marker is easily repeated by the force of the wind. If repeated, it is difficult to say that the inverted solid D is standing on the green, so that the function as a marker is greatly lost. In order to overcome such a fatal defect, axes A, B, and C to be embedded in the green surface are conventionally provided. However, markers with axes A, B, and C have this and fatal drawbacks as described above.

  Secondly, since the hinge part F is provided, it is possible to open and close the inverted solid D, but this is also a problem because the hinge part F protrudes. That is, this type of marker is put on the green or removed by hand in golf. Now, in such a case, if there is a hinge part F protruding, the hand may be injured by the hinge part F in some cases. When it is in a pocket, it may get caught in the clothing fabric and damage the fabric.

  From such a point of view, the marker of Patent Document 5 is never satisfactory.

  Accordingly, the first problem to be solved by the present invention is that it is difficult to repeat during use, and the function as a marker is sufficiently exerted. However, when not in use, it is easy to hold because of a planar structure. Is to provide a marker that is very unlikely to hurt hands or damage clothing.

  The second problem to be solved by the present invention is to provide a marker having the above features at a low cost.

The first problem is a marker comprising a base body, an inverted solid, and a connecting means for connecting the base body and the inverted solid,
The connecting means includes
A recess provided in one of the base body and the inverted solid;
A convex portion provided on the other of the base body and the inverted solid fitting into the concave portion;
The base body in which the concave portion is formed or the inverted solid, and the shaft insertion hole formed in the convex portion;
A pivot shaft that pivotally supports the inverted solid inserted through the shaft insertion hole,
This is solved by a marker characterized in that an open angle regulating mechanism capable of raising the inverted solid only at an open angle of 90 ° or less is provided.

In particular, a marker comprising a base body, an inverted solid, and a connecting means for connecting the base body and the inverted solid,
The connecting means includes
A recess provided in one of the base body and the inverted solid;
A convex portion provided on the other of the base body and the inverted solid fitting into the concave portion;
The base body in which the concave portion is formed or the inverted solid, and the shaft insertion hole formed in the convex portion;
A pivot shaft that pivotally supports the inverted solid inserted through the shaft insertion hole,
An open angle restriction mechanism is provided that can raise the inverted solid only at an open angle of 90 ° or less,
The open angle regulating mechanism is configured such that, when the inverted solid is opened at the maximum open angle, a part of the inverted solid abuts on the base body, and the inverted solid cannot be raised at an angle larger than that. It is solved by a marker characterized by that.

The first and second problems are markers comprising a base body, an inverted solid, and a connecting means for connecting the base body and the inverted solid,
The connecting means includes
A recess provided in one of the base body and the inverted solid;
A convex portion provided on the other of the base body and the inverted solid fitting into the concave portion;
The base body in which the concave portion is formed or the inverted solid, and the shaft insertion hole formed in the convex portion;
A pivot shaft that pivotally supports the inverted solid inserted through the shaft insertion hole,
An open angle restriction mechanism is provided that can raise the inverted solid only at an open angle of 90 ° or less,
This is solved by a marker characterized in that the base body in which the concave portion is formed or the outside of the inverted solid concave portion is cut out and formed into a concave shape.

In particular, a marker comprising a base body, an inverted solid, and a connecting means for connecting the base body and the inverted solid,
The connecting means includes
A recess provided in one of the base body and the inverted solid;
A convex portion provided on the other of the base body and the inverted solid fitting into the concave portion;
The base body in which the concave portion is formed or the inverted solid, and the shaft insertion hole formed in the convex portion;
A pivot shaft that pivotally supports the inverted solid inserted through the shaft insertion hole,
An open angle restriction mechanism is provided that can raise the inverted solid only at an open angle of 90 ° or less,
The open angle restricting mechanism is configured such that, when the inverted solid is opened at the maximum open angle, a part of the inverted solid abuts the base body, and the inverted solid cannot be raised at an angle larger than that. ,
This is solved by a marker characterized in that the base body in which the concave portion is formed or the outside of the inverted solid concave portion is cut out and formed into a concave shape.

  In the present invention, the base body is particularly heavier than the inverted solid. This is because the base body is configured to be heavier, so that even when an inverted solid is caused, the stability is excellent. Therefore, since it is difficult to fall down, it has an excellent function as a marker.

  As a technique for increasing the weight of the base body, it is conceivable that the base body is made of a material having a higher specific gravity. That is, even if the thickness of the base body and the inverted solid is the same, if the base body is made of a material having a higher specific gravity, the base body is heavier even if the size is the same, so that the stability is excellent.

  However, if the area and thickness of the base body and the inverted solid are the same, it is difficult to determine which is the base body. In some cases, you may not notice and place a light falling solid on the green and repeat it.

  Therefore, it is preferable to employ a technique in which the thickness of the base body is increased and thus the base body is made heavier. That is, in the present invention, in particular, the thickness of the base body is made thicker than the thickness of the inverted solid.

  If the base body is heavier than the falling solid, it is difficult to repeat even when the falling solid occurs. However, if the stability on the green (lawn) is taken into consideration, it is preferable that the base body is heavy. That is, for example, it is preferably made of metal. In addition, although it is a metal, it cannot be said that it is so preferable in the case of a light metal with small specific gravity, such as Al and Mg. For example, it is preferably made of a metal having a specific gravity of 2 or more.

  If the marker of this invention comprised as mentioned above raise | generates a fall solid and it is set | placed, this fall solid will be very easy to see. That is, when used, the original function as a marker is maximized.

  Moreover, the marker of the present invention is difficult to repeat even in a state where an inverted solid is caused. That is, it is excellent in stability and excellent as a marker.

  Further, when not used, if the tilted solid is tilted, the marker of the present invention has a planar (two-dimensional) structure, and is provided in markers such as Patent Documents 1, 2, and 4. Easy to hold because there is no shaft to be embedded in the green surface. For example, it can be easily stored in a pocket and can be easily held by a magnet attached to a sun visor.

  Moreover, since there is no protruding part like patent document 5, there is very little fear of injury when it is picked up. In addition, when it is in a pocket, it is difficult to get caught in the fabric, and accidents that damage the clothes are unlikely to occur.

  Then, if the concave part is formed on the base body or the outside of the inverted solid concave part, and the concave part is formed in a concave shape, the dimensional accuracy of the fitting part can be improved from the beginning when the concave part and the convex part are fitted. You don't have to keep it high. For example, if the inside dimension of the recessed portion is set to be slightly larger than the outside width of the projecting portion, there is a gap, so that the operation of fitting the projecting portion into the recessed portion becomes easier. However, if the dimensional relationship between the two is loose (there is a gap), there is nothing to support the inverted solid even if the inverted solid is raised, so the inverted solid is likely to fall down. With this, the function as a marker is not achieved. Therefore, the dimensional relationship between the concave portion and the convex portion needs to be somewhat tight (so that there is no gap). That is, if the dimensional relationship is tight, the frictional resistance between the two is large, so that the raised solid is supported by the large frictional resistance, and the falling solid is unlikely to fall. Thus, it is preferable that the dimensional accuracy of the concave portion and the convex portion is loose during assembly and is tight after assembly. Therefore, if the shape as described above is applied, if force is applied from both sides of the recess after assembly, both side portions of the recess will bend inward, and the dimensional accuracy between the recess and the projection may be loose during assembly. After assembly, it can be kicked. If the dimensional accuracy is relaxed at the time of assembly, the assembly is simplified and the manufacturing cost is reduced accordingly.

  1 to 4 show a first embodiment of a marker for a golf ball according to the present invention. FIG. 1 is a perspective view in a state (planar (two-dimensional) state) in which an inverted solid is collapsed. 2 is a perspective view in a state in which the inverted solid is opened (raised), FIG. 3 is a plan view of the base body, and FIG. 4 is a plan view of the inner side of the inverted solid (a bottom view of the inverted solid).

  The marker M of the present invention has a base body 1 and an inverted solid 2. Furthermore, it has a connection mechanism for connecting the base body 1 and the inverted solid 2.

  The base body 1 is a disk having a diameter φ of about 15 to 25 mm and a thickness of about 1.5 to 2.5 mm, for example. And it has a specific gravity of 2 or more and is made of a metal adsorbed by a magnet, for example, a magnetic metal such as iron. The disc-shaped base body 1 is formed with a recess 3 having a notch from its end, for example, a width of 2 mm and a depth dimension of about 4 mm. And the hole 5 is formed from the edge part of the disk shaped base body 1 in the location of the position 4a, 4b of the both sides of the recessed part 3. FIG. The upper surface of the base body 1 is configured as a mirror surface.

  The inverted solid 2 is a disk having a diameter φ of about 15 to 25 mm and a thickness of about 0.5 to 1.2 mm, for example. And it has a specific gravity of 2 or more and is made of a metal adsorbed by a magnet, for example, a magnetic metal such as iron. The size of the base body 1 is almost the same except that the thickness is small. Of course, the size may be slightly smaller than the base body 1, but it is not significantly larger. That is, (weight of the inverted solid 2) / (weight of the base body 1) <1. In particular, the value is configured to be 0.6 or less. There is no particular restriction on the lower limit, but it seems that 0.05 is the limit. The inverted solid 2 is provided with a convex portion 6 that protrudes from its end to the main surface of the inverted solid. The convex portion 6 has a dimension that can be fitted into the concave portion 3. For example, the width of the convex portion 6 is 1.9 mm, and the depth (the radial direction of the disk) dimension is about 3.9 mm. The protruding height of the convex portion 6 is the thickness of the base body 1. Of course, the protruding height may be slightly smaller, but it has never been said to be substantially larger than the thickness of the base body 1. The protrusion 6 is provided with a hole 7 corresponding to the hole 5. In addition, in a state where the convex portion 6 is fitted in the concave portion 3 and the inverted solid 2 is attached to the base body 1, when the inverted solid 2 is opened at an angle of 90 °, a part of the top surface 6 a of the convex portion 6 is It is configured to abut against the innermost end 3a of the recess 3 and not to open more than that, for example, an angle of 100 °, for example. Alternatively, when the inverted solid 2 is opened at an angle of 90 ° in a state where the convex portion 6 is fitted in the concave portion 3 and the inverted solid 2 is attached to the base body 1, a part of the inner surface of the inverted solid 2 is the base body. It is configured to abut against one side surface and not open further, that is, an angle of, for example, 100 °. That is, an opening angle regulating mechanism having a maximum opening angle of 90 ° is provided. In addition, the lower surface (inner surface) of the inverted solid 2 is configured as a mirror surface.

  And although not shown in figure, the pin is inserted in the holes 5 and 7, and the fall solid 2 is connected with the base body 1 so that opening and closing (turning) is possible within the range of 90 degrees. In addition, the size of the pin is not much different from the size of the hole 7, and even if the open angle (standing angle: starting angle) of the inverted solid 2 is 30 °, the inverted solid 2 is naturally in its state. Configured to be maintained.

  The marker M configured as described above is placed in a pocket when not in use. If the inverted solid 2 is overlaid on the base body 1, the marker M is two-dimensional, i.e., flat, and does not get in the way. And since there is no projecting part, it will not get caught in the pocket fabric and damage the fabric. Moreover, even if it touches with a hand, it will not be damaged. Even if it is attracted and held by the sun visor with a magnet, it does not interfere with golf. Therefore, the retention is very excellent.

  On the other hand, when marking the ball position on the green, it is only necessary to open (raise) and place the inverted solid 2 on the green. And, as in the prior art, there is no need for the troublesome trouble of providing a support column and embedding it.

  Now, since the embedded column part is not provided on the marker, the holding property and workability are excellent, but the stability when the marker is placed is lacking because there is no embedded column part. For example, there is a high risk of repetition.

  Therefore, in the above, the maximum opening angle of the inverted solid 2 is configured to be 90 °. As a result, even when the inverted solid 2 is placed in a fully opened state, the stability of the center of gravity is excellent and it is difficult to repeat. In particular, since irregularities are natural on the lawn, in some cases, the stability is very poor. Therefore, since it is naturally expected to be used in a situation where the stability is poor, it is highly preferable that the maximum opening angle is 90 °, preferably 80 °. Also, by making the weight of the base body 1 heavier than the weight of the inverted solid 2, the stability when the inverted solid 2 is raised is increased. For example, the stability of the marker M is increased by reducing the thickness of the inverted solid 2 and reducing the weight of the inverted solid 2. Moreover, if the thickness of the inverted solid 2 is reduced, it is easy to determine which is the base body 1 (inverted solid 2), which is convenient for marking. That is, the risk of placing the marker M in a form that can be easily repeated is greatly eliminated. Therefore, the mark function is greatly achieved from such a viewpoint. Further, if the thickness of the base body 1 is increased, the holes 5 can be easily formed. On the other hand, since the hole 7 opened on the side of the inverted solid 2 is the location of the convex portion 6, even if the thickness of the inverted solid 2 is thin, there is no problem as long as the convex portion 6 is thick.

  In addition, since the surface (inner surface and / or outer surface) of the inverted solid 2 is configured as a mirror surface, it is very easy to see when the inverted solid 2 is raised.

  The base body 1 is preferably made of a magnetic metal having a large specific gravity. On the other hand, the inverted solid 2 may not be made of a magnetic metal. For example, it may be made of resin. Furthermore, the specific gravity may be small.

  Further, although the concave portion 3 is provided on the base body 1 and the convex portion 6 is provided on the inverted solid 2, the concave portion 3 may be provided on the inverted solid 2 and the convex portion 6 may be provided on the base body 1.

  FIG. 5 shows a golf ball marker according to a second embodiment of the present invention and is a plan view of a base body.

  The marker of this embodiment and the marker of the said embodiment differ only in the base body. That is, as can be seen from the comparison between FIG. 3 and FIG. 5, at positions 4a and 4b on both sides of the recess 3 formed in the base body 1, portions of the positions 4a and 4b are cut out. is there. That is, the concave portion 3 is literally formed in a concave shape. Accordingly, the positions 4a and 4b on both sides of the recess 3 are narrow projecting pieces (the ridges are also capes and peninsulas). This means that the piece-like portions 4a and 4b are easily bent. This is obvious when FIG. 3 and FIG. 5 are compared.

  And if comprised as mentioned above, after the assembly as a marker, the concave width dimension (inside dimension) of the recessed part 3 in the base body 1 and the convex width dimension (outside dimension) of the convex part 6 in the inverted solid 2 ) Is not a tight relationship (that is, = (≈)), even if the inverted solid 2 is raised in the fitting state of the concave portion 3 and the convex portion 6, the frictional resistance at the fitting portion is small, so that it immediately falls down. It will come back to the original. The falling solid 2 can be kept standing when the falling solid 2 is raised when the frictional resistance at the contact portion (fitting portion) between the falling solid 2 and the base body 1 is large. Accordingly, the function as a marker can be achieved because the inverted solid 2 can be maintained in a standing state, and therefore the frictional resistance is increased, that is, the concave width dimension (internal dimension) of the concave portion 3 in the base body 1. And the convex width dimension (outside dimension) of the convex part 6 in the inverted solid 2 must be tight (that is, = (≈)).

  However, if the concave width dimension (inner dimension) of the concave portion 3 in the base body 1 and the convex width dimension (outer dimension) of the convex portion 6 in the inverted solid 2 are tight, it is very difficult to assemble. In particular, it is very difficult to assemble the hole 5 and the hole 7 so that the pins are inserted so that the holes 5 and 7 are aligned with each other. In order to improve this workability, at the initial stage of assembly, the concave width dimension (inner dimension) of the concave portion 3 in the base body 1 is slightly larger than the convex width dimension (outer dimension) of the convex portion 6 in the inverted solid 2. It is preferable that And if it does in this way, it is easy to make it fit so that the hole 5 and the hole 7 may correspond.

  Therefore, at the initial stage of assembly, that is, when the base body 1 or the inverted solid 2 is pressed, the concave width dimension (internal dimension) of the concave portion 3 in the base body 1 is the convex width dimension (external dimension) of the convex portion 6 in the inverted solid 2. After forming the base body 1 and the inverted solid 2 to be slightly larger than the dimensions), combining them, and passing the pins, narrow projecting pieces 4a, such as capes and peninsulas on both sides of the recess 3, If 4b is bent inward, that is, if the concave width dimension (inner dimension) of the concave portion 3 in the base body 1 and the convex width dimension (outer dimension) of the convex portion 6 in the inverted solid 2 are tight, The frictional resistance increases, and when the falling solid 2 is raised, the falling solid 2 can stand still.

  Therefore, if the base body 1 (or the inverted solid 2) in which the concave portion 3 is formed as shown in the present embodiment, the outer side of the concave portion 3 is formed in a concave shape, the marker assembling cost is low. In addition, after assembling the marker, the function as the marker is fully exhibited.

  In addition, 8 is a recessed part formed in the inverted solid 2 opposing surface of the base body 1. FIG. For example, a photograph of the owner is attached to the recess 8. And since the base body 1 is thicker than the inverted solid 2, it is easy to form the recess 8.
