Description

  The present invention relates to a laser beam irradiation device used for golf putting practice and a golf putter to which the laser beam irradiation device is attached.

  There are no putters that you must enter with a putter, and there are no putters that you never enter. However, there are good and bad putters due to individual differences. It depends on the person's physical strength, motor nerves or putting form. If the product concept of the putter matches the person, then the putter is “a good putter” for that person. The market is therefore flooded with countless types of putters. Under these circumstances, the inventors of the present invention have made it possible to select a putter grip and adjust the length in order to cover differences in height, weight, and putting style in a pendulum type putter. We have developed a putter that can adjust the weight, which incorporates the weight of the head into the design, and a putter practice machine that is suitable for use with this putter. Of these, the present invention relates to a laser beam irradiation apparatus as one of putter practice machines.

  That is, for example, in the known putter 111 shown in FIG. 12, a laser beam irradiation device 112 for indicating a hitting target direction is provided as a training machine (see Patent Document 1).

  However, in this conventional laser beam irradiation apparatus 112, the laser beam hitting the irradiated object is only visually recognized as a pinpoint “point”. According to the explanation, when the line 113 itself drawn by the laser beam can be recognized according to the brightness of the place to practice, it is not necessary to irradiate the pin 114 or provide an irradiation plate. In fact, you can't just choose a dark place. Therefore, according to this prior art, the user has to practice while looking at the above “points” far from the address position, so that it is difficult to imagine the putting line, and thus the practice efficiency is not very good. .

  In the above prior art, the putter 111 itself is a practice putter. Therefore, even if the practice is carried out while irradiating the laser beam, another putter must be used for the competition, so that there is a disadvantage that the practice efficiency is not so good.

That is, the laser beam is irradiated toward the front of the head 31 over the head body 32.

Further, as shown in FIG. 9, a diffusion lens 83 having a cylindrical shape is installed in the laser light irradiation part 82 of the laser light irradiation body 75, and the irradiated laser light is diffused in the vertical direction so as to be irradiated. The laser beam R hitting the object is configured to be linear as shown in FIG. The laser beam is initially irradiated as a line, but when passing through the lens 82, the line changes to a surface. This surface is a surface that is orthogonal to the surface including the face surface 33 and faces the vertical direction of the head 31 (the direction orthogonal to the paper surface in FIG. 2A). This surface is a surface diffusing in a fan shape, and a depression angle θ ₁ (for example, 22.5 degrees) and an elevation angle θ ₂ (for example, 22.5 degrees) are set for the fan. Accordingly, when the laser beam having such a planar shape hits a flat ground or floor surface, a straight line perpendicular to the surface including the face surface 33 is formed, and when hitting a vertical wall surface, a vertical straight line is formed (on the head 31). If there is no tilt). Note that FIG. 1 shows only a part of a line by the laser beam R for the convenience of drawing, but this line actually extends long in the left direction in the figure. In FIG. 9B, the lens 83 is fixed to the inner surface of the case 81 with an adhesive 85 or the like together with a support 84 made of hard rubber.

The switch unit 97 is electrically connected to the power source unit 87 and the irradiation apparatus main body 72 via wiring, and emits laser light only when the switch main body 99 is pressed.

  Returning to the description of FIG. 8, as described above, the first center line 48 that displays the center line in the width direction of the head 31 is provided on the upper portion of the head 31, that is, on the upper surface of the head body 32. A center line (also referred to as a third center line) 86 for displaying the center line in the width direction of the head 1 is provided on the upper surface of the upper case 74 of the irradiation apparatus main body 72 of the laser beam irradiation apparatus 71. As shown in the figure, since the first and third center lines 48 and 86 are set to have different height positions, when the user views the head 31 from directly above, the first and third center lines 48 and 86 appear as one straight line, and when the user looks at the head 1 from obliquely above, the first and third center lines 48 and 86 appear to be shifted from each other. Further, since the second center line 49 provided at the rear end of the overhanging portion 35 is also provided on the center line in the width direction of the head 31, when the user views the head 31 from directly above, the first and first The two center lines 48 and 49 and the third center line 86 appear as one straight line. When the user views the head 31 from obliquely above, the first and second center lines 48 and 49 and the third center line 86 Appear to be offset from each other. Therefore, the user can practice using these characteristics to position the line of sight directly above the head 31.

  According to the head 31, the laser beam irradiation device 71, and the putter 1 including these, the following operational effects can be obtained.

  That is, first, a plurality of (six) weight fixing portions 40, 41, and 42 having different sizes are provided at the rear portion of the head 31, and a weight 43 having a size corresponding to an arbitrary weight fixing portion 40, 41, 42 is provided. , 44 and 45 are fixed so that the weight of the head 31 is set to the weight desired by the individual user. By selecting whether to fix the weights 43, 44, 45 having such a size, the weight of the head 31 can be adjusted relatively finely according to physical strength, foam, and the like. Although the adjustment is gradual, fine adjustment is possible because 49 patterns are prepared as described above in this embodiment. Therefore, the user can use one head 31 as an optimum weight, and thus an ideal putting form can be obtained without difficulty.

  Further, a horizontal plate-like protruding portion 35 is provided at the rear portion of the head main body 32, and weight fixing portions 40, 41, 42 are provided on the protruding portion 35, and a golf ball is formed on the protruding portion 35 from its lower surface side. Since the hole-shaped ball fitting portion 38 for detachably fitting 61 is provided, the weight of the head 31 can be adjusted by the user, and each time the user picks up the golf ball 61 on the ground. It is possible to pick up using the putter 1 without bending. The user holds the grip 11 of the putter 1 and presses the ball fitting portion 38 of the head 31 against the golf ball 61 to fit the golf ball 61 to the ball fitting portion 38. Since the ball fitting portion 38 is provided as a through hole in the horizontal plate-like projecting portion 35 provided at the rear portion of the head main body 32, the user connects the ball fitting portion 38 and the golf ball 61. Both can be aligned while looking at both.

  Further, since the weight fixing portions 40, 41, 42 are provided symmetrically on the toe side and the heel side of the ball fitting portion 38 provided on the overhang portion 35, the toe side weight fixing portions 40, 41, 42 are provided. If the weights 43, 44, 45 are fixed to the head, the weight balance of the head 31 is shifted to the toe side. Conversely, if the weights 43, 44, 45 are fixed to the weight fixing portions 40, 41, 42 on the heel side, The weight balance will approach the heel side. Further, if the weights 43, 44, 45 are fixed equally on the toe side and the heel side, the weight can be adjusted while keeping the balance without deviating the weight balance of the head 31 toward the toe side or the heel side. Therefore, the weight of the head 31 and its balance can be finely adjusted by selecting which size of the weights 43, 44, 45 to be fixed to which weight fixing portions 40, 41, 42 in this way. Can do.

  Further, as shown in the plan view of FIG. 2A and the like, the head 31 has a relatively small diameter circular hole (to the heel side and heel side of the relatively large diameter circular hole (ball fitting portion 38)). This is a novel configuration in which a plurality of weight fixing portions 40, 41, 42) are arranged. Therefore, it has so-called aesthetics in form and therefore has excellent design effects.

  Further, in the configuration of the laser beam irradiation device 71, the laser beam irradiated from the laser beam irradiation device 71 is diffused in a fan shape in the vertical direction, and the laser beam R hitting the irradiated object has a linear shape. Therefore, the user will practice putting while watching the “line” instead of the “point” of the pinpoint as in the past. Since the “line” that hits the flat ground or floor surface indicates a direction orthogonal to the face surface 33 of the head 31, the ball 61 rolls on this “line” if hit as it is. Therefore, it is possible for the user to easily imagine a putting line and to check whether or not the ball 61 can be hit along this line, so that the practice efficiency can be improved.

  Further, the laser beam irradiation device 71 is detachably attached to the head 31 of the putter 1, and is attached not directly to the practice putter but directly to the competition putter. Therefore, the user can attach the laser beam irradiation device 71 to the putter 1 and practice putting with the laser beam, and can remove the laser beam irradiation device 71 from the putter 1 and use the putter 1 as it is in the competition. Therefore, since the putter 1 that has been used in practice with laser light can be used as it is in the competition, it is possible to practice near the actual battle on a daily basis, thus increasing the practice efficiency.

  Further, in the laser beam irradiation device 71, its constituent elements are an irradiation device main body 72 that is detachably attached to the head 31 of the putter 1, a power supply unit 87 that is detachably attached to the shaft 21, and a detachable attachment to the grip 11. Since the laser beam irradiation device 71 is configured to be freely attached to the putter 1, the laser beam irradiation device 71 can be detachably attached to the putter 1. Therefore, the laser beam irradiation device 71 is detachable with respect to the putter 1 and can be carried while attached to the putter 1.

  Further, in the putter 1, a horizontal plate-like protruding portion 35 is provided at the rear portion of the head body 32, and a hole-shaped ball fitting for removably fitting the golf ball 61 to the protruding portion 35 from below is provided. Since the portion 38 is provided and the laser beam irradiation device 71 is fitted into the hole-shaped ball fitting portion 38 from above, the user picks up the golf ball 61 on the ground. The ball 61 can be picked up by using the putter 1 even if it is not bent every time, and the hole-shaped ball fitting portion 38 can be used as it is as a mounting hole of the laser beam irradiation device 71. It is possible. Therefore, it is possible to provide a putter club capable of exerting two functions in one hole provided in the projecting portion 35.

  Further, in the putter 1, a first center line 48 indicating the center line in the width direction of the head 31 is provided on the upper surface of the head 31 and on the upper surface of the head body 32, and the laser fitted into the ball fitting portion 38. A third center line 86 that similarly indicates the center line in the width direction of the head 31 is provided on the upper surface of the case 74 in the irradiation apparatus main body 72 at the upper part of the light irradiation apparatus 71, and the laser beam irradiation apparatus 71 is attached to the ball fitting portion 38. Since the first and third center lines 48 and 86 are configured to have different height positions in the fitted state, when the user views the head 31 from directly above, The three center lines 48 and 86 appear as one straight line, and when the user views the head 1 obliquely from above, the first and third center lines 48 and 86 appear to be shifted from each other. . Therefore, using this characteristic, the user can effectively perform the practice of positioning the line of sight directly above the head 31.

  Various modifications can be made to the above embodiment within the scope of the technical idea of the present invention. For example, the number of switches attached to the grip 11 is arbitrary, and the attachment method is also arbitrary. Although three switches 99 are attached in FIG. 10, one switch may be used as shown in FIG. Further, in FIG. 10, the switch 99 is attached by the attaching portion 98 made of a band, but an adhesive tape or the like may be used as shown in FIG.
