This invention relates to a bowling game board for enjoying playing a bowling game on a table.

Prior art bowling game boards of this kind are known wherein a bowler doll is provided on one end side of a base board on the top surface of which a lane is formed, a pin stand part where pins are arranged is provided on the other end of the base board, and, when the aforesaid bowler doll throws a bowl, the bowl hits pins arrangedly standing on the pin stand part, causing the pins to fall, and if a first throw fails to bring all the pins down leaving some pins unfallen, a second bowl is thrown after the fallen pins among the unfallen-left pins are removed by picking them up manually. An example of such a bowling game board is known from US 3 756 598.

The prior art bowling game boards, however, have problems not only that realism of bowling games is damaged because fallen pins must be removed by picking them up manually in case a first thrown bowl leaves some pins unfallen, but that a straight game cannot be played because standing pins slip out of place or fall down by being touched by a hand at the time of removal, and furthermore that it is troublesome that all pins need be rearranged manually to be stood on the pin stand part when all the pins are brought down by a first throw or after a second throw is finished.

This invention has been made in the light of the aforesaid problems and aims at providing a bowling game board wherein realism of bowling games is not damaged, a second throw can be continued by removing fallen pins rapidly and surely and by resetting the remaining pins as they originally stood, or a game can be resumed by automatically arranging and standing all pins rapidly and precisely after a second throw is finished or all the pins have fallen by a first throw.

The present invention as defined in claim 1 is achieving the aforementioned object.

In a second mode of the invention, the aforesaid pin arranging means is characterised by having guide members standingly provided on both the widthwise sides of the aforesaid pin stand part and a pin arranging device supported by, and movable upward/downward along, the aforesaid guide members; and the aforesaid pin arranging device is characterised by comprising a device body supported by, and movable upward/downward along, guide grooves each formed in the inner side of each of the aforesaid guide members, a pin throw-in case supported via elastic members by, and located in the middle of, this device body and provided with pitfalls formed in its bottom part for allowing the aforesaid pins to pass therethrough longitudinally, and an oscillation generating means for oscillating the aforesaid throw-in case.

In a third mode of the invention, each of the aforesaid pins is characterised by being equipped on its bottom part with a weight and an engagement projection, and engagement holes are characterised by being formed in the surface of the aforesaid pin stand part for causing the aforesaid pins to stand by insertion thereinto of engagement projections of pins coming down from pitfalls of the aforesaid arranging means.
