Special table 2007-503947 gazette Registered Utility Model No. 3045771

  In the invention disclosed in Patent Document 1, by hitting the ball against the cushion member of the putting device, the ball can be repelled by its repulsive force. However, the ball used in this golf practice tool has a flat portion in part so as to be able to move while sliding on the panel surface, and does not roll. The ball does not return to its original position, and it is not possible to practice putting with one ball continuously.

  Further, in the device disclosed in Patent Document 2, continuous putting practice can be performed by hitting a ball against a rail that is provided on the inner peripheral wall surface of the billiard table surface assembly device and whose outer surface is covered with an elastic member. it can. However, even if this assembling apparatus can be easily assembled and disassembled, a required space for assembling and arranging the assembling apparatus is required, and this apparatus is used in a relatively small place such as a room. There was a problem that it was impossible to practice.

  Therefore, an object of the present invention is to provide a putter training tool that can be used for continuous putting practice with a single ball even in a relatively small place such as a room and is excellent in carrying.

In order to solve the above-described problems, the present invention is directed to a frame having a longitudinal direction and a lateral direction, having a front side and a rear side, and an elastic repulsion positioned at the front end of the front side. It is a putter practice tool including a member.

According to the present invention, the frame body is formed of a hard plastic material, and the weight member formed of a metal material is fixed inside the front portion side where the repulsion member is located. The mass is larger than that on the rear side of the frame, and the repulsive member is formed of a rubber elastic elastic material with a substantially triangular cross section, and the top is directed forward, The height of the top of the repellent member is larger than the radius of a standard golf ball, and the lower surface of the repellent member is curved downward .

The present invention includes the following preferred embodiments in addition to the characteristic configuration.
(1) The frame includes a base, a holding portion extending in the lateral direction at the front end of the frame and upward from the base, and upward from the base on the rear side of the frame, and And a gripping portion extending rearward from the lateral central portion of the holding portion.
(2) A target portion that is recessed in a semicircular shape having the same diameter as the competition cup is provided in the central portion of the holding portion .
(3) A concave portion for placing a golf ball and a guide groove portion extending backward from the concave portion are provided on the upper surface of the gripping portion .
(4) Anti-slip means is provided on the bottom surface of the frame.

  According to the putter training tool according to the present invention, even in a relatively narrow place such as a room, the putted ball is applied to a repellent member attached to the front surface of the frame, and the ball is used by utilizing the repulsive force. By rebounding to the putting position, continuous putting practice can be performed. Further, since the weight member is fixed to the front side of the frame, when the ball hits the repulsive member, there is no possibility that the putter training tool will be lifted or displaced due to the impact.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  1 is a perspective view of the putter training tool 10, FIG. 2 is an exploded perspective view of the training tool 10, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. In FIG. 1, for the sake of convenience, the golf ball 30 is indicated by a broken line.

  The practice tool 10 has front and rear directions X1, X2 and a lateral direction Y, a frame body 11 formed of a hard plastic material, a repellent member 13 projecting forward X1 of the frame body 11 formed of an elastic member, And a weight member 12 fixed to the front side of the frame body 11.

  The frame body 11 includes a base portion 14, a holding portion 15 that extends in the lateral direction Y at the front end of the frame body 11 and upward from the base portion 14, and a holding portion that extends upward from the base portion 14 on the rear side of the frame body 11. And 15 gripping portions 16 extending from the center portion in the lateral direction Y to the rear X2. The holding part 15 has an opening 20 which is located on the front side and extends in the lateral direction Y. The insides of the holding unit 15 and the gripping unit 16 are hollow, and a pair of ribs 25 that are spaced apart from each other in the lateral direction Y are formed inside the holding unit 15 (see FIG. 2).

  The base portion 14 includes an upper surface portion 14a, a lower surface portion 14b, and a peripheral surface portion 14c extending downward over the left and right sides and the rear side. A pair of concave groove portions 18 are formed on both sides of the grip portion 16 in the upper surface portion 14a. The holding portion 15 is formed with a target portion 19 which is a semicircular shape having the same diameter as the competition cup, which is a target for putting. The upper surface 16a of the gripping portion 16 has a recess 21 for placing the ball 30 when the practice tool 10 is not used, and a guide groove portion for lowering the ball 30 from the recess 21 to the floor surface when used. 22 is formed.

  The weight member 12 is made of a metal material such as iron or lead, and has a bottom portion 23 extending in the rear direction X2 at a lower portion of the base portion 14 of the frame body 11 and a wall portion 24 extending upward from the front end of the bottom portion 23. In addition, the cross section is substantially L-shaped. A repellent member 13 is attached to the front surface 24 a of the wall portion 24 via an adhesive (not shown), and the repellent member 13 projects forward from the opening 20 of the holding portion 15. A support member 26 having a receiving portion 27 and a fixing portion 28 extending forward and having a U-shaped cross section is fixed to the wall portion 24 by welding or bonding.

  The repellent member 13 is made of a repellent elastic material such as rubber or urethane foam, and has a substantially triangular cross section. Specifically, in order to exhibit the desired effect, those formed from an elastic member having a specific gravity of 1.0 or less and a hardness of 40 to 50 degrees are preferable. The repulsive member 13 has a triangular cross section, the upper side surface 13A extends smoothly and obliquely upward, and the lower side surface 13B is curved slightly convex downward. As long as the desired effect of the present invention is achieved, the repulsive member 13 may have a circular cross section or an elliptical cross section in which the cross section is not triangular and at least the lower side surface 13B is curved outward. . The repulsion member 13 extends over the entire area of the opening 20 of the holding portion 15, but may be attached only to the front surface 24 a of the wall portion 24 located below the target portion 19. In this case, when the put ball 30 directly hits a portion where the repulsion member 13 is not attached, that is, the wall portion 24, a collision sound is generated, so that the ball 30 comes off the target portion 19 (cup). Can be confirmed.

  As shown in FIG. 3, in the assembled state of the practice tool 10, the wall portion 24 of the weight member 12 is inserted into the holding portion 15 of the frame 12 from the curved upper end portion 31 side, and is inserted. The upper end portion 31 is in contact with the inner peripheral wall 17 of the inclined holding portion 15 and the rib 25 formed so as to narrow toward the upper side, and the wall portion 24 is stably fixed inside the holding portion 15. Has been. Further, in order to fix the weight member 12 inside the frame body 11, a plurality of screws 36 are inserted into the insertion holes 37 provided in the lateral direction Y on the rear side of the bottom 23 of the weight member 12 and spaced apart by a given dimension. It is inserted and fastened to a screw hole (not shown) formed in the lower surface portion 14 b of the base portion 14. The screw holes located on both sides of the base portion 14 extend further upward from the upper side surface 14a of the base portion 14 to form a protrusion 40 (see FIG. 2).

  Since the upper end portion 31 of the wall portion 24 is in contact with the inner peripheral wall 17 and the rib 25 of the holding portion 15, the wall portion 24 is located rearward X <b> 2 from the front end 11 a of the holding portion 15. Accordingly, the lower end 39 of the front end surface 11a of the holding portion 15 contacts the upper side surface 13A of the elastic member 13, and the repulsive member 13 supports the lower end portion 39 that contacts the upper side surface 13A and the lower side surface 13B. It is clamped by the receiving part 27 of the member 26. Thus, the repulsive member 13 is stably held and fixed in a state of protruding from the front end surface 11a of the holding portion 15 to the front X1, and thus the back side surface 13C bonded to the wall portion 24 during use. Even if a part of the frame is peeled off from the wall portion 24, there is no possibility that the frame body 11 will fall off in a delusion. Further, the frame body 11 may not have the opening 20, the front end surface 11 a may form the entire front surface of the frame body 11, and the repulsion member 13 may be attached to the front end surface 11 a.

  Referring to FIG. 2 again, anti-slip means 41 is provided on the bottom surface 29 of the frame 11. Specifically, after the weight member 12 is fixed to the inside of the frame body 11, the lower coefficient of the bottom 23 of the weight member 12 and the lower surface part 14 b of the base portion 14 of the frame body 11 have a high friction coefficient from the soft plastic material. A non-slip sheet 41 formed so as to be formed is attached. The bottom surface 29 of the frame 11 on which the sheet 41 is pasted includes a fixing portion 28 of the support member 26, a bottom surface 23 of the weight member 12, a bottom surface of the groove 18, and an extending portion 44 extending downward from the top surface portion 14 a of the base portion 14. Are formed in the same plane. Even when the practice tool 10 is used in a room whose floor is made of flooring, tiles, etc., the sheet 41 is adhered to the bottom surface 29 of the frame 11, when the hit ball hits the repellent member 13. The position of the practice tool 10 does not shift due to the shock. Further, a bottom cover (not shown) that covers the entire bottom surface 29 of the frame body 11 may be attached to the peripheral surface portion 14c of the base portion 14 of the frame body 11, and the sheet 41 may be adhered to the bottom cover. By attaching the bottom cover in this way, it is possible to prevent dust and dust from entering the training tool 10.

  4A to 4C are cross-sectional views of the training tool 10 showing a process until the put ball 30 hits the center of the repellent member 13 and the repellent member 13 repels the ball 30. FIG.

  FIG. 4A is a view at the moment when the put ball 30 hits the top 48 of the repulsive member 13, and the top 48 is in contact with the surface of the ball above the center of the ball 30. Thus, in order to return the ball 30 rolling in the direction D1 toward the training tool 10 to the put position using the repulsive force of the repulsive member 13, the contact position with the top 48 of the ball 30 is It is preferable that the height of the top portion 48 is set so as to be above the center. Specifically, the height h of the top 48 is preferably 24 to 28 mm with respect to the standard ball size (diameter 43 mm). When the height h is equal to or less than the radius (21.5 mm) of the ball, that is, when the top 48 is positioned below the radius of the ball 30, the contact surface of the top 48 with the ball 30 and the lower surface deformation due to the collision of the ball The amount becomes too large, and the repulsive force of the top 48 becomes excessive. As a result, the top portion 48 is displaced together with the frame 11 so as to be non-perpendicular to the straight line D1 of the rolling direction of the ball 30, so that the ball 30 does not return normally to the putting position due to the repulsive force of the top portion 48. Incidentally, in order for the ball 30 to return normally to the putting position, the frame 11 is installed such that the top 48 of the repulsive member 13 is perpendicular to the rolling direction D1 straight line of the ball 30 by the putting. For this purpose, it is preferable that the normally installed frame 11 is not displaced by the collision of the ball 30.

  Further, description will be made with reference to FIG. FIG. 4B is a diagram showing a state in which the ball 30 hits the top 48 of the repellent member 13 and absorbs the impact to elastically deform the top 48 of the repellent 13. When the ball 30 rolling in the clockwise direction d1 hits the top 48 of the repellent member 13, the repellent member 13 is elastically deformed, and due to its restoring force, the ball 30 is subjected to a rotational torque in the counterclockwise direction d2. The force to change and repel acts. At that time, if the ball 30 is repelled only by the repulsive force of the pointed top 48, the expected repulsive force is not fully exerted, the ball 30 does not return to the putting position, or by continuous putting practice. Excessive force acts only on the top 48, and there is a possibility that it may be elastically deteriorated or damaged. However, in the present invention, the lower side surface 13B of the repellent member 13 is curved downward, and when the ball 30 hits the top 48, the top 48 pushed downward is curved not only at the top 48 but also downward. Since the ball 30 can be repelled using the repulsive force of the entire lower side surface 13B, a stronger repulsive force is generated compared to the case where only the repulsive force of the top portion 48 is used, and the top portion 48 is excessively excessive. Since force does not act, even if putting practice is continued, there is no possibility that the top 48 is elastically deteriorated or broken.

  As described above, the ball 30 repelled by the repulsive force of the repellent member 13 is returned to the putting position while rotating in the counterclockwise direction d2 opposite to the clockwise direction d1 that rolls toward the practice tool 10 side. In this case, a force acts on the repulsive member 13 obliquely backward d3, that is, in a direction in which the practice tool 10 is lifted, so that the ball 30 hits the repellent member 13 at a relatively high speed. In such a case, the exercise tool 10 may be lifted rearward and may be displaced. In order to prevent such misalignment, in the present invention, a weight member made of a metal material such as iron or lead having a larger specific gravity than a plastic material is provided inside the holding portion 15 located on the front side of the practice tool 10. 12 is fixed. That is, since the weight member 12 is fixed in the holding portion 15, even if the ball 30 hits the repulsion member 13 at a relatively high speed, the weight member 12 serves as a weight, and the exercise tool 10. There is no risk that the will float rearward and cause displacement. Moreover, since the sheet 41 adhered to the outer surface of the bottom portion 23 of the weight member 12 is brought into close contact with the floor by the weight of the weight member 12, even if an external impact is applied to the frame body 11, the practice tool is irritated. The position of 10 does not shift.

  Thus, in order for the weight member 12 to play a role as a weight, specifically, in the putting practice at a distance of 2 to 3 m, the weight member 12 preferably has a mass of 1.0 to 2.0 kg. . Moreover, in the training tool 10, it is preferable that the mass of the front side where the repulsion member 13 is located is larger than the mass of the rear side. This is because when the rear side portion is heavier than the front side portion, when the ball 30 hits the repulsive member 13, a predetermined portion of the rear side portion serves as a fulcrum and the front side may be lifted upward.

  In the illustrated embodiment, the frame 11 and the weight member 12 are formed separately, and the latter is fixed to the former. (1) The frame is made of a metal material such as aluminum, iron, copper or the like having a desired mass. 11 and the portion corresponding to the weight member 12 may be formed integrally. In addition to (2) the form shown in the figure, for example, the frame body 11 is not rectangular but may be of another shape such as a circle, and the weight member 12 is not L-shaped in cross section, but has other shapes. It may be. In short, an indispensable requirement in the present invention is that the mass on the front side of the frame 11 of the practice tool 10 is larger than that on the rear side, and as long as this requirement is satisfied, the practice tool 10 is ) And other forms including (2).

  As shown in FIG. 4C, after the ball 30 is repelled, the repulsive member 13 is restored to its original shape, and the ball 30 returns toward the putting position (direction D2). can do.

  As described above, the inside of the frame 11 is hollow, and the weight member 12 is also relatively light, so that the practice tool 10 can be easily carried. When carrying, the grip part 16 can be stably held with one hand by inserting the thumb and the middle finger into the concave groove part 18 provided in the base part 14. In addition, when the practice tool 10 is used, a dedicated mat or other equipment is not required, so that continuous putting practice can be performed even in a relatively small place such as a room.
