Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following is a detailed description of the embodiments, but not a limitation of the present invention, and all technical solutions obtained by a person having ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The appearances of the terms "first," "second," and the like in the description herein are intended to be illustrative only and not to be construed as limiting. The term "latitude circle" as used herein refers to a circle obtained by intersecting a plane perpendicular to the rotation axis with a curved surface of rotation. Reference herein to a ball is to billiards or to pinballs as an aid to the description of the hole. The gradient mentioned in the invention is consistent with the daily slope concept of the hillside, and the flatter the gradient is, the smaller the gradient is, the minimum gradient angle is 0 degree; the steeper the slope, the larger the maximum slope angle is 90 degrees.

Fig. 1 shows a perspective view of an embodiment of a hole, and fig. 2 is a schematic half-section view of an embodiment of a hole, which will now be described with reference to the two figures.

The hole comprises a hole wall 1, a hole opening 2, a bottom surface 3 and a target area 4. The hole wall 1 is encircled into an annular mountain shape, the outer surface 11 of the hole wall is a path for the ball 5 to enter the target area 4, the range of the outer surface 11 is formed by the surface between the bottom edge of the hole wall 1 and the hole opening 2, and the shape of the outer surface can influence the service performance of the ball hole; the maximum height of the hole wall 1 is the height of the hole opening 2, the difficulty of entering the ball is directly influenced, the ball entering is difficult when the height is too high, for example, the hole opening 2 is higher than the diameter of the ball body 5, and the ball which is too low at the hole opening 2 is easy to roll out of the target area 4. The opening 2 is circular and is located at the top of the opening wall 1, in a use state, the opening 2 is parallel to the table board of the game platform, the round opening 2 enables the ball 5 to enter the target area 4 from any angle around the ball to be equal in chance, the size of the opening 2 also influences the difficulty degree of entering the ball, the larger the caliber of the opening 2 is, the easier the ball entering is, and otherwise, the difficulty degree of entering the ball is increased. The bottom surface 3 is positioned at the bottom of the hole wall 1, the bottom surface 3 is used for keeping the ball hole and the game table surface tightly attached, and the structure of the bottom surface is preferably a plane and preferably a larger friction coefficient; at least, the outer edge of the bottom surface 3 is attached to the game table surface when in use, which is beneficial to the fact that the ball hole is not easy to be overturned or moved when in use. The space enclosed by the hole wall 1 is the target area 4 of the ball, and whether the ball 5 falls into the area is used as the basis for judging the score. On the whole, the outer edge of the hole wall 1 is low, the hole opening 2 is highest, and the edge of the bottom surface 3 is tightly attached to the game table. In the game process, the ball 5 rolling from any direction on the plane rolls from bottom to top along the outer surface 11 of the hole wall 1 and falls into the target area 4 through the hole 2, and then the score is regarded as the score. In fig. 2, the height of the hole wall 1 is about 3/4 times the diameter of the ball 5, and the diameter of the hole 2 is about 1.68 times the diameter of the ball 5, and the applicant considers that the embodiment obtained by referring to the two values can make the playing difficulty moderate and the player can obtain good entertainment experience.

Furthermore, the outer surface 11 of the hole wall 1 is a rotating curved surface, the maximum latitude circle of the rotating curved surface is the intersection circle of the rotating curved surface and the bottom surface 3, and the diameter of the latitude circle of the rotating curved surface is gradually reduced from bottom to top. The surface of revolution plays a key role in changing the motion state and trajectory of the sphere 5. The smooth rotating curved surface can keep the rolling state of the ball body 5, reduce the impact force, reduce the bounce of the ball body 5 and gradually reduce the ball speed; the rotating curved surface has the characteristic of central axis symmetry, which enables the hitting opportunities in any direction to be equal.

Preferably, the outer surface 11 of the hole wall 1 comprises a conical inclined surface, the conical inclined surface is used as a main part, the gradient of each point on the inclined surface is constant, and the conical inclined surface is simple in structure and easy to process. In engineering practice, the round corner can be processed near the opening 2; the slope of the inclined plane is too large, and the ball hole moves due to the fact that a large horizontal component force is generated when the ball body 5 touches the hole wall 1, and the slope angle is preferably lower than 45 degrees.

Preferably, the outer surface 11 of the hole wall 1 comprises a concave curved surface, and the concave curved surface is taken as a main part, and the slope of the concave curved surface is gradually increased from bottom to top. As will be explained in more detail below with reference to FIG. 2, the letters and combinations thereof identified in the figures are interpreted as: the curve AD is a generatrix of the outer surface 11 of the hole wall 1, A is a generatrix first end point, and is positioned on an intersecting circle of the outer surface 11 and the bottom surface 3; b is a first inflection point, and a first touch point of the sphere 5 and the hole wall 1 is near B; c is a second inflection point; d is a second end point of the bus, which is the highest point of the bus; the curve BC is a concave curve, which is rotated along the generatrix rotation axis to obtain a concave curved surface, and the gradient gradually increases from bottom to top within the range of the concave curved surface. The lower the inflection point B is, the smaller the slope angle of the inflection point B is, so that the smaller the bounce of the ball body 5 when the ball body 5 touches the hole wall 1 is, the more the smooth ascending of the ball body 5 is facilitated, and the more the position movement of the hole is facilitated to be ensured. The reason can be found by stress analysis: at the moment of touch, the ball body 5 generates impact force on the hole, and the orthogonal decomposition of the impact force finds that the lower the touch point B is, the smaller the gradient angle is, the smaller the horizontal component of the impact force is, namely the smaller the thrust force borne by the hole is; the downward vertical component of the impact force is also reduced, namely the upward reaction force on the ball body 5 is reduced, and the ball body is not easy to jump upwards; the superposition of the gravity of the ball body 5 and the dead weight of the hole is unchanged, which is beneficial to maintaining the maximum friction force at the bottom of the hole. In engineering practice, in order to guarantee a reasonable strength of the wall 1 at the edge, the necessary material thickness must be preserved, so that the inflection point B cannot approach the end point a indefinitely. After the touch, during the rolling climbing of the sphere 5, the friction between the sphere 5 and the surface of the hole wall 1 is small, and the possibility of hole displacement is lower than that near the point B. The ball 5 rolls upwards along the concave curve, the slope of the curved surface is larger and larger, the kinetic energy of the ball 5 is rapidly and stably converted into potential energy, and when the point D is reached, if the kinetic energy of the ball 5 is slightly higher than zero, the ball 5 just falls into the target area 4. At point C, the slope is maximum, and assuming that at point C, the ball 5 still has a large kinetic energy, the ball 5 will leave the hole wall 1 and continue to move upwards, and then there will be two cases: if the gradient of the point C is small, the sphere 5 easily jumps over the hole 2 and cannot enter the target area 4; if the slope of point C is large, for example close to 90 degrees, the direction of the ball 5 continuing to move is almost along the direction of the rotation axis, i.e. the ball 5 remains above the hole 2, and the ball 5 can easily fall into the target area 4 when it loses its kinetic energy. The effect can be shown as the point C is closer to the opening 2 and the slope is larger, but in engineering practice, chamfering treatment is performed near the opening 2, and the consideration factors include ensuring the strength, the appearance and the like of the opening 2, so that the inflection point C cannot be infinitely close to the end point D. In summary, the outer surface 11 of the hole wall 1 can influence the service performance of the hole, and the concave curved surface is best in reducing the displacement possibility of the hole and improving the hole entering possibility.

Preferably, the hole wall 1 is made of soft rubber or soft plastic material, such as silica gel material, which has the following advantages: the impact effect of the ball body 5 and the soft ball hole is generated locally, only local deformation is generated, after the impact force is eliminated, the deformation is recovered, the horizontal impact force is buffered and dispersed, and the horizontal impact force cannot be directly transmitted to the bottom of the ball hole to cause the displacement of the ball hole.

If a hard framework is arranged in the body or the inner wall of the hole wall 1, the shape of the hole can be better kept.

Preferably, if the game table is a table top, the hook surface of the magic tape is attached to the bottom surface 3, the table top is used as the suede surface of the magic tape, and the possibility that the ball hole slips is lower due to the application of the magic tape at the position.

The outer surface 11 of the annular hole wall 1 is provided with a flocking layer or attached with flannelette, and if the main body of the hole wall 1 is made of hard materials, the flocking layer or the flannelette can play a good buffering effect.

The target area 4 is enclosed by the cavity wall 1, and is typically a through hole or a cavity therein, which may also be designed as a pit, in the illustrated embodiment, the target area 4 is a through hole. All or part of the sphere 5 enters the target area 4 and is constrained by the wall 2. In the game, the entry of the ball 5 into the target area 4 is considered as a score.

As is clear from the above description: compare with traditional pocket type ball hole, the utility model discloses a ball hole has different structures, need not be fixed mounting on game platform by fixed mounting, only need according to the rule put can, simple installation. The hole-entering type billiard game can be played by the Kaolun table after the hole-entering type billiard game is placed on the table top of the Kaolun table; the finger-ball game can be played by placing the finger-ball game table or the ground without digging a hole.
