Description

  The present invention relates to a putting practice cup.

  When golf putting practice is performed on an indoor carpet or on an outdoor lawn surface, a flat cup is used instead of the golf hole. The putting practice cup has a cup portion corresponding to the hole, and has a structure in which the ball can roll into the hole portion.

Specifically, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2-84974), a device having a cup portion provided with a peripheral wall having a conical circumferential surface shape that is easily bent by a golf ball, As disclosed in Document 2 (Japanese Utility Model Laid-Open No. 5-63573), an instrument in which the periphery of the cup portion is formed into an inclined surface, and also disclosed in Patent Document 3 (Japanese Utility Model Laid-Open No. 61-130268). As described above, an appliance having a structure in which a part of the peripheral wall of the cup portion is opened is known.

The above-mentioned device has a constant cup size (size that allows golf balls to be cupped in), and as a training device for learning more accurate putting, Patent Document 4 (Japanese Utility Model Laid-Open No. 3-39074). As described in Japanese Laid-Open Patent Publication No. Hokukai), there is known an instrument in which a cup portion is formed of a concentric ring body and a hole diameter of the cup portion is determined by selective fitting of the ring body.

JP-A-2-84974. Japanese Utility Model Laid-Open No. 5-63573. Japanese Utility Model Publication No. 61-130268. Japanese Utility Model Publication No. 3-39074.

  As a practice instrument for further improving the accuracy of putting, the instrument disclosed in Patent Document 4 is known. However, in order to adjust the hole diameter (target size: the width that can be cupped in), a ring is used. Since the body is sequentially fitted and the ring body that is not used is separated from the instrument body, when practicing while changing the putting situation such as the direction and distance of putting, it is necessary to Since the ring body exists, the adjustment work of the hole diameter is troublesome, and the separated member (ring body) is likely to be lost.

Therefore, the present invention proposes a new putting practice cup that can adjust the cup-in width in a single body.

  The cup for practicing putting according to the present invention has a rear peripheral wall portion formed on a semicircular upper surface of a disc-shaped base portion of an appropriate size, and a base portion can be mounted on the rear peripheral wall portion so as to follow the circular shape. It is characterized by comprising a front peripheral wall that can be moved in and out.

Thus, it is used as a target for putting in the same way as the conventional practice cup, and it is assumed that the hit ball passes through the part where the front peripheral wall does not exist and reaches the base part to be a cup-in. The width of the cup-in is adjusted by adjusting the appearance of the front peripheral wall so that the practice of improving the putting accuracy becomes possible.

Further, the present invention (Claim 2) is the above-described putting practice cup, in which the rear peripheral wall portion is formed in a cylindrical shape, and the front peripheral wall is inserted into the rear peripheral wall portion so as to be retractable. The cup-in width can be easily set by inserting and removing the peripheral wall.

Furthermore, the putting practice cup according to the present invention (Claim 3) is formed by incorporating a front peripheral wall into each of both end portions of the rear peripheral wall portion, and the center line of the cup-in is changed by adjusting the appearance of the left and right front peripheral walls. Without setting the cup-in width.

The putting practice cup according to the present invention (Claim 4) has a rear peripheral wall having an upper surface portion, a front peripheral wall having an upper surface portion that follows the back surface of the upper surface portion of the rear peripheral wall, A latch receiving through hole in which a latching portion is formed by embedding the biased latching ball in an exposed state from the upper surface portion of the peripheral wall, and the top portion of the locking ball is fitted to the upper surface portion of the rear peripheral wall. Are arranged at appropriate intervals.

Thus, the locking ball biased upward is pressed downward when moving up and down, moves upward at the through hole position, and the top part fits into the through hole. Even if the position of the instrument is moved by maintaining the locked state, the cup-in width is not changed.

  The present invention is configured as described above, and has been able to provide a practice instrument that requires a desired accuracy by adjusting the width (where the front peripheral wall does not exist) that can be cupped in by adjusting the appearance of the front peripheral wall, and The operation for adjusting the cup-in width is also facilitated.

  Next, an embodiment of the present invention will be described. The putting practice cup shown in the embodiment includes a base portion 1, a rear peripheral wall portion 2, and a front peripheral wall 3.

The base portion 1 has a disc shape having an appropriate size. The rear peripheral wall portion 2 is provided in a fixed state on the upper surface thereof, and the front peripheral wall 3 is incorporated in a movable state.

The rear peripheral wall portion 2 is a cylindrical shape provided with a top surface portion 21 on the upper surface rear semicircle of the base portion 1 and is provided in a semicircular shape, and the top portion of a locking ball 35 described later is fitted to the upper surface portion 21. The latch receiving through holes 22 are formed at appropriate intervals.

The front peripheral wall portion 3 is two arcuate bodies having a size inserted into the cylindrical portion of the rear peripheral wall portion 2 and includes an upper surface portion 31 that follows the back surface of the upper surface portion 21 of the rear peripheral wall. A locking portion 32 is provided.

The locking portion 32 forms a vertical hole portion 33, and a ridge 34 is embedded in the vertical hole portion 33, and a locking ball 35 urged upward by the ridge 34 is provided on the upper portion of the vertical hole portion 33. The part 31 is embedded so that the upper part is exposed.

Thus, the front peripheral wall portion 3 is mounted in the rear peripheral wall portion 2 so as to be able to protrude and retract, and the top portion of the locking ball 35 of the locking portion 32 is fitted into the locking receiving through hole 22 so that the locking state is established. It will be.

Therefore, by adjusting the degree of protrusion of the front peripheral wall portion 3, the width that allows the golf ball to enter the base portion, that is, the cup-in width can be set arbitrarily, so that it can be used as a putting target as in the conventional practice cup. In addition, the practice accuracy can be adjusted by setting the cup-in width.

In the present invention, the rear peripheral wall portion 2 is not formed into a cylindrical shape, and a structure having a bowl-shaped upper surface portion or a structure having only a peripheral wall surface by changing the locking structure is possible.
