Abstract
A board game structure of the type consisting of a plurality of playing pieces and a game board on which the playing pieces are moved having a given axis with a plurality of elongated rectilinear sliders mounted thereon for movement in side-to-side relationship to each other at a given common angle to the axis of the board. The board game has an improved detent structure for restraining each of the sliders in predetermined positions in their movement. Such improvement is based on the use of detent cam surfaces and detent cam followers held in engagement solely by the force of gravity acting on the sliders. An improvement in the structure for retaining the sliders on the game board against the force of gravity is disclosed.
Claims18
In a board game including a plurality of playing pieces and a game board on which said playing pieces are moved, said game board having a given axis and a plurality of elongated rectilinear sliders mounted thereon for movement in side-to-side relation with respect to each other at a common angle to said given axis of said board, detent means tending to restrain each of said sliders in predetermined positions in their movement with respect to each other, and stop means for establishing the maximum extent of said movement of said sliders with respect to each other, the improvement wherein said detent means comprises a detent cam surface and a detent cam follower held in engagement solely by gravity forces acting on said sliders with said plurality of sliders each being provided with one of said detent cam surface and said detent cam follower and said game board being provided with the other of said detent cam surface and said detent cam follower and wherein said plurality of sliders are each restrained against removal from said game board by a pin engaged with a slot, said plurality of sliders each being provided with one of said pin and said slot and said board being provided with a plurality of the other of said pin and said slot.
In a board game including a plurality of playing pieces and a game board on which said playing pieces are moved, said game board having a given axis and a plurality of elongated rectilinear sliders mounted thereon for movement in side-to-side relation with respect to each other at a common angle to said given axis of said board, detent means tending to restrain each of said sliders in predetermined positions in thier movement with respect to each other, and a stop means for establishing the maximum extent of said movement of said sliders with respect to each other, the improvement wherein said sliders are each mounted on said board by means comprising a pin having a head captured in a slot with said plurality of sliders each being provided with one of said pin and said slot and said game board being provided with the other of said pin and said slot;
- wherein said detent means comprises a detent cam surface and a detent cam follower held in engagement solely by gravity forces acting on said sliders with said plurality of sliders each being provided with one of said detent cam surface and said detent cam follower and said game board being provided with the other of said detent cam surface and said detent cam follower and wherein said head of said pin associated with each said slider is held out of engagement with said slot associated with each said slider when said detent cam surface and said detent cam follower associated with each said slider are held in engagement by said gravity forces acting on each said slider.
In a board game including a plurality of playing pieces and a game board on which said playing pieces are moved, said game board having a given axis and a plurality of elongated rectilinear sliders mounted thereon for movement in side-to-side relation with respect to each other at a common angle to said given axis of said board, detent means tending to restrain each of said sliders in predetermined positions in their movement with respect to each other, and stop means for establishing the maximum extent of said movement of said sliders with respect to each other, the improvement wherein said game board is provided with a first plurality of elongated rectilinear rails projecting from one surface thereof and extending at said common angle with respect to said given axis of said game board, said plurality of rails being spaced from each other along said given axis of said game board, and wherein said sliders each comprise an open bottom hollow box having a pair of side walls, a pair of end walls and a top wall with each of said plurality of rails being loosely received within said open bottom of a different one of said sliders, each of said elongated rectilinear sliders having a length substantially greater than the length of said elongated rectilinear rails received therein.
