A game ball can fall downward from between them.

  As shown in FIGS. 5 to 7, each of the obstacle protrusions 27 to 29 protrudes from the base plate 25 to the front side and has a hollow cylindrical shape whose front end is closed by the front wall portions 35 to 37, and the front wall portions 35 to 37 thereof. Decorative plates 38 to 40 are arranged on the front surface. The decorative plates 38 to 40 are detachably fixed to the obstacle protrusions 27 to 29 by fixing means 41 to 43 on the back side. The front surfaces of the obstacle protrusions 27 to 29 may be used for decoration.

  The first obstacle projections 27 are arranged in a substantially eight-shape on both sides of the top portion 44, and the front collision wall 45 and the rear collision wall 46, and the front collision wall 45 and the rear collision wall 46 on the side opposite to the outer guide rail 11 And a bottom wall 47 connected to each other at the top portion 44 so that a game ball, that is, a return ball, which attempts to return to the outer guide rail 11 side beyond the top portion 44 is prevented. Return ball blocking means 48 is provided.

  The second obstacle protrusion 28 has a rectangular tube shape including a front collision wall 50 and a rear collision wall 51 and a bottom wall 52 that connects the front collision wall 50 and the rear collision wall 51 on the side opposite to the outer guide rail 11. . The third obstacle protrusion 29 has a rectangular tube shape including a front collision wall 53 and an upper collision wall 54 and a bottom wall 55 that connects the front collision wall 53 and the upper collision wall 54 on the side opposite to the outer guide rail 11. .

  The return ball blocking means 48 includes a blocking portion 49 formed integrally with the top portion 44 of the first obstacle protrusion 27, and the interval W 1 between the blocking portion 49 and the outer guide rail 11 is adjacent to the first obstacle protrusion 27. 2 The distance W2 between the obstacle protrusion 28 and the outer guide rail 11 and the distance W3 between the third obstacle protrusion 29 and the outer guide rail 11 are smaller than each other, and are about 1.5 times the diameter of the game ball. . The distances W1 to W3 between the respective obstacle protrusions 27 to 29 and the outer guide rail 11 are the largest distances W2 on the second obstacle protrusion 28 side, and then the distance W3 on the third obstacle protrusion 29 side, the first obstacle protrusions. 27 in order of the interval W1.

  The front collision wall 45 of the first obstacle protrusion 27 is disposed on the upper side in the moving direction of the game ball driven along the outer guide rail 11, and the rear side collision wall 46 is provided on the lower side. The end of the first obstacle protrusion 27 on the outer guide rail 11 side is connected to the outer guide rail 11 so that a game ball from the guide passage 19 can easily move along the outer guide rail 11 into the game area 13. It is almost parallel.

  The blocking portion 49 is configured such that the game ball reflected and bounced off by the second obstacle protrusion 28 and the third obstacle protrusion 29 moves in the reverse direction along the back-side collision wall 46 toward the top portion 44 side. The rear collision wall 46 protrudes upward from the outer guide rail 11 side end to the second obstacle projection 28 side so as not to enter between the top guide portion 44 and the outer guide rail 11. In addition, the front end side of the blocking part 49 has an acute angle shape, and the game ball bounced back on the second obstacle protrusion 28 and the third obstacle protrusion 29 side is struck as much as possible and dropped downward.

  The front collision wall 45 is disposed on the guide passage 19 side of the blocking portion 49 of the first obstacle protrusion 27 so as to face the outlet 19a. The front collision wall 45 is formed long in the vertical direction so that the game ball stalls immediately after passing through the outlet 19a of the guide passage 19 and many of the game balls separated from the outer guide rail 11 to the inside of the game area 13 can easily collide. At the same time, the colliding game ball is inclined downward at an angle α with respect to the vertical line so that the game ball quickly falls. The back side collision wall 46 is inclined obliquely downward from the blocking portion 49 toward the side opposite to the outer guide rail 11 so that the game ball falls downward from between the second obstacle protrusions 28.

  The front collision wall 50 of the second obstacle protrusion 28 is arranged on the upper side in the moving direction of the game ball driven along the outer guide rail 11, and the rear side collision wall 51 is provided on the lower side. The front collision wall 53 of the third obstacle protrusion 29 includes an upper vertical collision wall 53a and a lower inclined collision wall 53b. The vertical collision wall 53a is provided in a substantially vertical shape that is short in the up-down direction, and the second obstacle protrusion is such that most of the game balls that have collided with the vertical collision wall 53a fall on the rear-side collision wall 51 of the second obstacle protrusion 28. 28 on the upper side of the rear side collision wall 51. The inclined collision wall 53b is inclined downward and obliquely downward at an angle β with respect to the vertical collision wall 53a, and the game ball flying from the outer guide rail 11 side, the rear-side collision wall 51 of the second obstacle projection 28. A game ball or the like reflected from the player is reflected downward.

  The upper collision wall 54 is formed in a substantially arc shape from the upper end of the vertical collision wall 53a to the upper center side of the game area 13, and the distance W3 from the outer guide rail 11 becomes smaller as the game area 13 becomes closer to the center side. Is arranged.

  Fixing means 41 to 43 for fixing the decorative plates 38 to 40 to the obstacle protrusions 27 to 29 are formed in the fitting protrusions 56 to 58 protruding from the back surface of the decorative plates 38 to 40 and in the respective obstacle protrusions 27 to 29. Further, the fitting projections 56 to 58 penetrate through the bottomed cylindrical fitting tube portions 59 to 61 into which the fitting projections 56 to 58 are detachably fitted from the front side and the rear end side wall portions of the fitting tube portions 59 to 61. And a screw 62 screwed into the fitting protrusions 56-58. The decorative plates 38 to 40 are positioned by positioning protrusions 63 to 65 and positioning holes 66 to 68 formed on the front wall portions 35 to 37 and into which the positioning protrusions 63 to 65 are fitted.

  The fitting cylinders 59 to 61 are close to the rear collision wall 46 in the first obstacle protrusion 27, approximately in the center between the rear collision wall 51 and the bottom wall 52 in the second obstacle protrusion 28, and in the third obstacle protrusion 29. The upper collision wall 54 and the bottom wall 55 are formed in close proximity to each other. The fitting cylinder portion 59 of the first obstacle protrusion 27 is integrally formed close to the inner side of the rear side collision wall 46 and is connected to the inner side of the front side collision wall 45 via a reinforcing rib 69. The fitting cylinder portion 60 of the second obstacle projection 28 is connected to the inside of the front collision wall 50 and the back collision wall 51 via the reinforcing rib 70, respectively. The fitting cylinder portions 59 to 61 of the third obstacle protrusion 29 are formed adjacent to the upper collision wall 54 and the bottom wall 55.

  Each obstacle protrusion 27 to 29 is not affected by the game ball that is driven from the guide passage 19 into the game area 13 during the game. Therefore, the thickness S1 is the base so that it can sufficiently withstand the collision of the game ball. The plate 25 is configured to be thicker than the plate thickness S2, and the inside thereof is partitioned into a plurality of independent spaces in a front view by fitting cylinder portions 59 to 61, reinforcing ribs 69 and 70, and the like. Reinforced from the inside by cylindrical portions 59 to 61 and reinforcing ribs 69 and 70.

  The obstacle protrusions 27 to 29 need only be thick on the side of the collision walls 45, 46, 50, 51, 53, 54, which is at least a portion where the game ball easily collides, and the game on the side opposite to the outer guide rail 11. The thickness of the bottom walls 47, 52, and 55 on which the ball is difficult to hit may be substantially the same as that of the base plate 25.

  When a game ball is fired from the launching means in the game, the game ball is guided to the game area 13 side through the guide passage 19 between the guide rails 11 and 12, and then passes through the blocking piece 21 from the outlet 19a to the outer guide. It is driven into the game area 13 along the rail 11.

  The inertial force of the game ball differs depending on the magnitude of the impact force of the game ball at the launching means, and the game ball collides with any of the plurality of obstacle projections 27 to 29 depending on the magnitude of the inertial force. The falling direction of the game ball can be irregularly changed by the obstacle protrusions 27 to 29.

  For example, when the inertial force of the game ball is weak, the game ball stalls on the front side of the first obstacle projection 27 through the blocking piece 21, and most of the game ball is placed on the front collision wall 45 of the first obstacle projection 27. It collides or falls downward without colliding with the front collision wall 45. Further, if the inertial force of the game ball is strong, the game ball passes on the first obstacle protrusion 27 along the outer guide rail 11 and reaches the second obstacle protrusion 28 side. Then, the game ball having a large inertial force moves toward the third obstacle protrusion 29, and the game ball having a small inertial force moves toward the second obstacle protrusion 28.

  For example, when a game ball moved to the third obstacle projection 29 side collides with the vertical collision wall 53a, the game ball is reflected to the second obstacle projection 28 side according to the magnitude of inertia force, the difference in the collision direction, and the like. Then, it falls while reflecting one or more times between the rear collision wall 51 and the inclined collision wall 53b, or exceeds the rear collision wall 51 of the second obstacle projection 28 and the front collision wall 50, or more than that. 1. Falling while reflecting toward the obstacle projection 27 side. In addition, the game ball that collides with the front collision wall 50 of the second obstacle projection 28 is reflected and falls from between the first obstacle projection 27 and the second obstacle projection 28, or falls on the rear collision wall 46 of the first obstacle projection 27. Collide and fall.

  The game ball that has collided with the front collision wall 50 of the second obstacle protrusion 28 and the vertical collision wall 53a of the third obstacle protrusion 29 is bounced off onto the rear collision wall 46 of the first obstacle protrusion 27, and then this rear side collision. While moving along the inclined surface of the wall 46, it may move in the direction indicated by the arrow a in FIG.

  However, even if there is a game ball that rolls in the reverse direction on the back side collision wall 46 of the first obstacle protrusion 27 in this way, the second obstacle protrusion 28 that is on the upper side from the end on the outer guide rail 11 side of the back side collision wall 46. Since there is the blocking portion 49 protruding to the side, the game ball is not guided by the outer guide rail 11 from the back side collision wall 46 and gets over the first obstacle protrusion 27. Further, since the gap W1 between the blocking portion 49 and the outer guide rail 11 is small, the game ball jumped off on the second obstacle projection 28 side is directly between the first obstacle projection 27 and the outer guide rail 11. It is possible to reduce the chance of entering a return ball.

  During the game, game balls collide with the obstacle protrusions 27 to 29 without interruption. However, the plate thickness S1 on the side of at least the collision walls 45, 46, 50, 51, 53, and 54 of the respective obstacle protrusions 27 to 29 is larger than the plate thickness S2 of the base plate 25, and the cylindrical obstacle projections 27 to 29 includes a reinforcing portion composed of fitting tube portions 59 to 61, reinforcing ribs 69 and 70, and the like, and the reinforcing protrusions 27 to 29 are reinforced from the inside by the reinforcing portions. Even if the game ball continues to hit 29 specific parts, the obstacle protrusions 27 to 29 are not damaged thereby. For this reason, durability of each obstacle protrusion 27-29 improves, and the fall direction of a game ball can be changed irregularly by this obstacle protrusion 27-29.

  Further, since the reinforcing portions such as the fitting cylinder portions 59 to 61 and the reinforcing ribs 69 and 70 are located inside the corresponding portions of the collision walls 45, 46, 50, 51, 53 and 54, the fitting cylinder portions 59 to 61 are provided. The reinforcing portions such as the reinforcing ribs 69 and 70 do not cause death or injury in the movement of the game ball.

  Further, since the obstacle protrusions 27 to 29 are partitioned into a plurality of independent spaces by the fitting cylinder portions 59 to 61, the reinforcing ribs 69 and 70, etc., the obstacle projections 27 to 29 are obstructed by the fitting cylinder portions 59 to 61, the reinforcing ribs 69 and 70, etc. The rigidity of the protrusions 27 to 29 is further improved.

  Therefore, even in the case of the second obstacle protrusion 28 having no reinforcing rib inside the front collision wall 50, damage to the front collision wall 50 can be prevented in advance. Further, the front collision wall 53 of the third obstacle projection 29 is bent in a square shape in the middle in the vertical direction to form a vertical collision wall 53a and an inclined collision wall 53b. The rigidity is improved. Therefore, it is not necessary to provide a reinforcing portion on all the back sides of the collision walls 45, 46, 50, 51, 53, 54 of the respective obstacle protrusions 27-29.

  FIG. 8 illustrates a second embodiment of the present invention. In this embodiment, the front collision wall 45 of the first obstacle protrusion 27 is inclined, so that when a game ball driven into the upper side of the game area 13 from the guide passage 19 collides, the game ball is inclined. It is comprised so that it may guide along the top part 44 side along.

  Even when the game ball is guided by the front collision wall 45 in this way, the game ball between the guide passage 19 and the first obstacle projection 27 is prevented by blocking the return ball by the return ball blocking means 48. Can reduce the collision.

  FIG. 9 illustrates a third embodiment of the present invention, and fitting cylinder portions 59 to 61 are provided on the inner side corresponding to all the collision walls 45, 46, 50, 51, 53 and 54 of the obstacle protrusions 27 to 29. Reinforcing portions such as reinforcing ribs 69, 70, 71 are provided.

  As described above, the collision walls 45, 46, 50, 51, 53, and 54 in which the game balls easily collide, except for the bottom walls 47, 52, and 55 near the intrusion prevention wall 30 portion among the obstacle protrusions 27 to 29. A reinforcing portion may be provided corresponding to all of the above.

  10A to 10D illustrate a fourth embodiment of the present invention. FIG. 10A shows an increased inclination angle of the back side collision wall 46 of the first obstacle protrusion 27. The rear side collision wall 46 of the first obstacle protrusion 27 can be similarly implemented in the case of such a steep inclination in addition to a gentle inclination with a gentle inclination angle.

  FIG. 10B shows the tip of the blocking portion 49 of the return ball blocking means 48 rounded in an arc shape. When emphasizing the prevention of the game ball moving to the outer guide rail 11 side along the back side collision wall 46 of the first obstacle protrusion 27, the tip of the blocking portion 49 is thus formed in an arc shape or other shape. In other words, the tip does not necessarily have to be acutely sharp.

  In FIG. 10C, the back side collision wall 46 of the first obstacle projection 27 includes a lower side inclined collision wall 46a and a standing collision wall 46b that stands from its upper end side, and the standing collision wall 46b is blocked by a blocking portion 49. It is said. Even if the rear side collision wall 46 is configured so as to be bent and recessed in the middle of the shape like this, the return ball blocking means 48 can be configured by the standing collision wall 46b. The back side collision wall 46 may be recessed in a circular arc shape when viewed from the front.

  In FIG. 10D, the back side collision wall 46 of the first obstacle protrusion 27 is formed in a step shape. The back side collision wall 46 is provided with a step 46e between its inclined portions 46c and 46d. Thus, the back side collision wall 46 may have inclined portions 46c and 46d and a step 46e.

  11 and 12 illustrate a fifth embodiment of the present invention. In this embodiment, one or a plurality of reinforcing ribs 69 in the front-rear direction protruding inward are integrally provided inside the front collision wall 45 and the rear collision wall 46 of the obstacle protrusion 27. The reinforcing rib 69 may be provided at least inside the collision walls 45 and 46 and may be provided inside the bottom wall 47.

  As described above, the reinforcing rib 69 may be integrally provided at least inside the front-side collision wall 45 and the back-side collision wall 46, and the collision walls 45 and 46 may be reinforced from the inside by the reinforcing rib 69. In this case, if the number of the reinforcing ribs 69 corresponding to each of the collision walls 45 and 46 is plural, the thickness of each of the collision walls 45 and 46 can be the same as the thickness of the base plate 25.

  13 and 14 illustrate a sixth embodiment of the present invention. In this embodiment, a blocking portion 49 of the return ball blocking means 48 is provided on the base plate 25 corresponding to the top 44 side of the first obstacle protrusion 27. The blocking portion 49 is provided so as to protrude forward from the base plate 25 plate in the vicinity of the inside of the game area 13 rather than on the extended line of the upper surface portion of the first obstacle protrusion 27. The protrusion height H1 of the blocking portion 49 may be substantially the same as the protrusion height H2 of the first obstacle protrusion 27, or may be slightly lower than the protrusion height H2 of the first obstacle protrusion 27.

  In this manner, the return ball blocking means 48 can be configured by providing the blocking portion 49 separately from the first blocking projection 27 in the vicinity of the top portion 44 of the first blocking projection 27.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not limited to this each Example, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the three obstacle protrusions 27 to 29 are provided along the outer guide rail 11 on the upper part of the game area 13, but the number of the obstacle protrusions 27 to 29 may be two or four. When a plurality of obstacle protrusions 27 to 29 are provided, a part of the obstacle protrusions, for example, the uppermost obstacle protrusion 29 may be configured by using a part of the front decoration frame 23 of the image display means 14.

  Further, the front ends of the plurality of obstacle protrusions 27 to 29 may be connected by a connection plate substantially parallel to the game board 10. The obstacle protrusions 27 to 29 may have any structure and shape that the game ball collides and bounces, and are not limited to the structures exemplified in the embodiments.
