In addition, 16 fitting areas A1 are formed in a matrix of 4 rows and 4 columns on the upper surface of the part body 51, and each of the fitting areas A1 includes 25 small first fitting portions. 53 are projected in a substantially hemispherical shape with a predetermined pitch P1 in a matrix of 5 rows and 5 columns. Further, a plurality of (9 in the first embodiment) round holes 54 for reducing the weight of the parts main body 51 are formed in the parts main body 51 in the vertical direction (FIG. 9) so as to avoid the fitting area A1. (A direction perpendicular to the paper surface).

Further, as shown in FIG. 1, the turf mat 3 is configured to be detachably divided into a plurality of (four in the first embodiment) flat turf mat parts 6. As shown in FIG. 10, each turf mat part 6 is directly or directly on a shock-absorbing rubber, silicone resin, urethane material, etc. on a synthetic resin substrate 61 (which may be a plate or a container). The artificial turf 62 is bonded and integrated through an elastic mat (not shown).

As shown in FIG. 1, a putting position PP for placing a golf ball 7 to be hit with a putter (not shown) is placed at substantially the center of one grass mat part 6 among the plurality of grass mat parts 6. As shown in FIGS. 1 and 10, a round hole 63 for a cup is formed in the vertical direction (perpendicular to the plane of FIG. 1). Direction). A cup (not shown) is detachably fitted into the cup hole 63, and an insertion hole (not shown) through which the golf ball 7 is inserted is formed at the bottom of the cup. . The turf mat part 6 is configured such that when the cup is not used, the cup hole 63 can be closed with a disc-shaped lid 64 as shown in FIG.

In addition, as shown in FIG. 10 (c), each turf mat part 6 has a large number of small second mating portions 65 on the lower surface of the substrate 61 and is almost hemispherical at a predetermined pitch P2 over the entire surface. It is recessed.

The first fitting portion 53 and the first fitted portion 83 constitute a first positioning mechanism 9 that positions the support column 8 on the base plate part 5 (therefore, the base plate 2). On the other hand, the pitch P4 of the second fitting portion 82 of the support column 8 is equal to the pitch P2 of the second fitted portion 65 of the turf mat part 6 (P4 = P2). The second fitting portion 82 and the second fitted portion 65 constitute a second positioning mechanism 10 that positions the turf mat part 6 (and thus the turf mat 3) on the support column 8.

Also, as shown in FIG. 4, between the base plate 2 and the turf mat 3, a golf ball 7 that is cupped in (the golf ball 7 that is contained in the cup fitted in the cup hole 63 of the turf mat part 6). ) To return to the vicinity of the putting position PP, a first ball collecting device 11 is provided. The first ball collecting device 11 is installed in the vicinity of a bowl-shaped ball path 13, a plurality of stands (supports) 15 that support the ball path 13 at an angle, and a putting position PP. And a ball storage box 17.

That is, between the base plate 2 and the turf mat 3, a space S1 having a predetermined interval (an interval equal to the height of the support column 8) L1 in the vertical direction is formed as shown in FIG. In this space S1, as shown in FIGS. 4 and 6, the ball passage 13 is supported by a plurality of stands 15 placed on the base plate 2 and is inclined at a predetermined inclination angle θ1 from the horizontal direction. It is installed with a slight inclination. The ball passage 13 has one end (the most upstream portion) 13a positioned below the insertion hole of the cup fitted in the cup hole 63 of the turf mat part 6 and the other end (the most downstream portion) 13b. It is connected to the ball storage box 17. Therefore, the golf ball 7 that has been cupped in is guided along the ball passage 13 while being rolled along the ball path 13 to the vicinity of the ball storage box 17, that is, the putting position PP.

As described above, the ball storage box 17 is not only one of the components of the first ball collection device 11 but also one of the components of the second ball collection device 12.

That is, around the turf mat 3, as shown in FIGS. 1 to 5, the two ball passages 14 are slightly inclined from the horizontal direction by a predetermined inclination angle θ2 in a form supported by a plurality of stands 16. Installed. Since the inclination angle θ2 of the ball passage 14 varies depending on the length of the ball passage 14 and the like, the inclination angle θ2 of the two ball passages 14 does not necessarily match. One end (uppermost stream part) 14 a of these ball passages 14 is located around the turf mat 3, and the other end (most downstream part) 14 b is connected to the ball storage box 17. Therefore, the golf ball 7 that fails to cup-in and exceeds the periphery of the turf mat 3 is guided along the ball storage box 17, that is, in the vicinity of the putting position PP while rolling along one of the ball paths 14. ing.

2, 3, 5, and 8, each stand 16 has an elliptic frustum-shaped stand main body 161, and a ball passage 14 is disposed above the stand main body 161.

Therefore, the putting practice device 1 can be easily assembled when performing the putting practice, and the storage space for the putting practice device 1 can be reduced when the putting practice is not performed.

Moreover, since the stand 15 has the elliptical truncated cone-shaped stand main body 151 as described above, the center of gravity is lowered and the stability is excellent. In addition, since the long axis of the stand 15 is substantially perpendicular to the axial direction of the ball path 13, the ball path 13 does not swing left and right when the golf ball 7 that has been cupped rolls along the ball path 13. Thus, the lateral displacement of the ball passage 13 can be suppressed.

Similarly, since the stand 16 has the elliptical frustum-shaped stand main body 161 as described above, the center of gravity is lowered and the stability is excellent. Moreover, since the long axis of the stand 16 is substantially orthogonal to the axial direction of the ball passage 14, the golf ball 7 that fails to cup-in and exceeds the periphery of the turf mat 3 rolls along the ball passage 14. In addition, the ball passage 14 can be strung so as not to swing from side to side, and the lateral displacement of the ball passage 14 can be suppressed.

The putting practice device 1 is mainly for practicing putting. Needless to say, however, the putting practice apparatus 1 can also practice shots such as a pitching wedge.
