Description

[Technical field]

[0001] The present invention relates to a hard ball protective member. [Background technology]

[0002] There is a golf simulation that allows a simulated experience of playing golf by actually swinging a golf club and hitting a golf ball at an image of a golf course projected on a screen installed in a room, monitoring the situation and displaying the ball's trajectory on the screen.

[0003] Although it is a simulation, a golf ball actually flies toward the screen, so a screen structure that will not be damaged even if hit by a golf ball is required. However, there are cases where the golf ball falls off the screen and hits the surrounding walls. In anticipation of such cases, protective cushioning material is installed on the surrounding walls that fall off the screen (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3181031 Summary of the Invention [Problem to be solved by the invention]

[0005] In a typical golf simulation, a player P swings a golf club G toward a screen SC that is suspended from a ceiling C and installed on a floor F with one end folded back toward the player P. The released golf ball B hits the surface of the screen SC and falls as it is, as shown in FIG.

[0006] However, although it is rare, there are cases where a golf ball B gets into the gap S between the screen SC and the floor F and hits the wall W behind the screen SC. To prevent this, a net N is sometimes stretched between the screen SC and the wall W to prevent collisions, as shown in Figure 6. However, if the golf ball B hits the net N multiple times, the net N may break, causing the golf ball B to hit the wall W directly.

[0007] On the other hand, as shown in Fig. 7, the folded portion of the screen SC may be fixed to the floor surface F with a stake ST to prevent the creation of a gap S. However, in this case, the fixed portion of the screen SC may be damaged by the impact when the golf ball B hits the screen SC.

[0008] The present invention has been made in consideration of the above circumstances, and has an object to provide a hard ball protection member that prevents a golf ball from colliding with a wall surface even if the golf ball gets into the gap between the screen and the floor surface. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention employs the following means. The hard ball protecting member of the present invention is a hard ball protecting member used in a sports simulation in which a hard ball is thrown, and comprises a rubber layer and a support layer whose surface is bonded to the back surface of the rubber layer, the rubber layer having a thickness capable of converting at least a portion of the kinetic energy of the hard ball into elastic deformation energy of the rubber layer, and the support layer having a thickness capable of absorbing at least the amount of elastic deformation in the thickness direction of the rubber layer by its own deformation, and the rubber layer is disposed between a gap formed between a screen onto which image information is projected and the floor surface and the rear wall surface of the screen, facing the back surface of the screen.

[0010] The hard ball protecting member according to the present invention further includes a coating layer disposed on the surface of the rubber layer.

[0011] In the hard ball protecting member according to the present invention, the support layer further comprises a resin layer and a wood layer. Effect of the Invention

[0012] According to the present invention, even if a golf ball gets into the gap between the screen and the floor surface, the golf ball can be prevented from colliding with the wall surface. [Brief description of the drawings]

[0014] An embodiment of the present invention will be described with reference to FIGS. The hard ball protection member 10 of this embodiment is a hard ball protection member used in a golf simulation (sports simulation) in which a golf ball (hard ball) B is hit, and comprises a rubber layer 11, a support layer 12 whose surface is bonded to the back surface 11a of the rubber layer 11, and a cover (coating layer) 13 arranged on the surface of the rubber layer 11.

[0015] The rubber layer 11 is formed of a material and with a thickness that allows most of the kinetic energy to be converted into elastic deformation energy of the rubber layer 11 without reflecting the golf ball B when it hits the rubber layer 11 from the thickness direction.

[0016] The material of the rubber layer 11 may be any of natural rubber, various synthetic rubbers such as polyisoprene, polyisobutylene, styrene butadiene rubber, butyl rubber, styrene isoprene block polymer, silicone rubber, etc., or a blend of any of these rubbers.

[0017] The support layer 12 includes a resin layer 15 and a wood layer 16. The resin layer 15 is made of a porous material that is flexible (pliable). The porous material may be either non-fibrous or fibrous, and examples of non-fibrous porous materials include foams and meshes made of polyurethane, polystyrene, polyvinyl chloride, polyethylene, etc. Examples of fibrous porous materials include woven fabrics and knitted fabrics.

[0018] The resin layer 15 has a thickness that is capable of absorbing the amount of elastic deformation of the rubber layer 11 when the rubber layer 11 is elastically deformed in the thickness direction, and preventing the wood layer 16 from being elastically deformed.

[0019] The wooden layer 16 may be made of, for example, a plywood board. The wooden layer 16 makes it possible to lean the chair against a wall W. The cover 13 may be made of leather or resin, and prevents the rubber layer 11 from being directly scratched or stained.

[0020] Next, the operation of the hard ball protection member 10 according to this embodiment will be described. This hard ball protection member 10 is disposed between a gap S formed between a screen SC onto which image information simulating a golf course is projected and a floor surface F, and a wall surface W on the rear side of the screen SC, with a rubber layer 11 facing the screen SC.

[0021] When playing golf, a player P swings a golf club G to hit a golf ball B toward a target (not shown) projected on a screen SC. Normally, the golf ball B will collide with the screen SC near the projection position of the target and fall onto the floor F.

[0022] However, there are cases where the shot goes wrong and the golf ball B is hit into the gap S formed between the screen SC and the floor surface F. In this case, the golf ball B that passes through the gap S collides with the cover 13 of the hard ball protection member 10.

[0023] At this time, the kinetic energy of the golf ball B is converted into energy required for elastic deformation of the rubber layer 11. At this time, the thicknesses of the rubber layer 11 and the resin layer 15 are determined so that the surface of the resin layer 15 on the side of the wood layer 16 is not deformed based on the momentum of the golf ball B, so that the golf ball B is prevented from colliding with the wall surface W.

[0024] On the other hand, when the golf ball B hits the rubber layer 11 in the thickness direction, most of the kinetic energy of the golf ball B is converted into the elastic deformation energy of the rubber layer 11, so that the golf ball B is prevented from being reflected by the rubber layer 11 and colliding with the screen SC.

[0025] In this way, not only can the wall surface W be protected, but also injuries and damages caused by unintended reflection of the golf ball B can be prevented.

[0026] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, a golf ball B is used as a hard ball in the embodiment, but the present invention is not limited to this and may be applied to sports other than golf that use a hard ball.
