Abstract
Abstract A game board or display board wherein in the disclosed perferred game board embodiment an eight by eight array of individually rotatable blocks, each having a plurality of exterior surfaces of different colors, are supported on eight longitudinal shafts. Each block is separated from its next adjacent block by a spacer which surrounds two longitudinal shafts. Spring biasing is used to create an axial force acting longitudinally along each shaft to frictionally grip each block and retain it with its original surface showing, or another selected face which has been turned up by finger pressure by a player. Reset bars are provided to relieve the axial force, thereby allowing each block to rotate under the action of a weighted lobe and to return to its starting position to begin a new game.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
A game and display board mechanism comprising: an enclosed frame; a plurality of shafts aligned parallel to each other and extending from a first to an opposite side of said frame; a plurality of blocks mounted for rotational movement on each of said shafts; said blocks each having a plurality of exterior surfaces and a weighted lobe located within each block to cause the display of a selected one of said exterior surfaces when said blocks are allowed to rotate freely on said shafts; biasing spring means for providing a predetermined force acting on each of said blocks to prevent inadvertent rotational movement; and manually actuated reset means for relieving said predetermined force to allow each of said blocks that are not displaying said selected one of said exterior faces to rotate under the action of its weighted lobe to display said selected one of said exterior surfaces.
Claim 2
Dependent Claim
148 words
A game and display board mechanism comprising: an enclosed frame; a plurality of shafts aligned parallel to each other and extending from a first to an opposite side of said frame; a plurality of blocks mounted for rotational movement on each of said shafts; said blocks each having a plurality of exterior surfaces and a weighted lobe located within each block to cause the display of a selected one of said exterior surfaces when said blocks are allowed to rotate freely on said shafts; biasing spring means for providing a predetermined force acting on each of said blocks to prevent inadvertent rotational movement; and manually actuated reset means for relieving said predetermined force to allow each of said blocks that are not displaying said selected one of said exterior faces to rotate under the action of its weighted lobe to display said selected one of said exterior surfaces.
Claim 3
Dependent Claim
34 words
The mechanism of claim 1 wherein each of said blocks is generally triangular in shape and has three exterior surfaces, and said weighted lobe is located opposite said selected one of said exterior surfaces.
Claim 4
Dependent Claim
25 words
The mechanism of claim 1 which additionally comprises spacer means located between adjacent blocks and extending between and surrounding at least two of said shafts.
Claim 5
Dependent Claim
50 words
The mechanism of claim 1 wherein said biasing spring means for providing a predetermined force acting on each of said blocks to prevent inadvertent rotational movement comprises means for creating an axial load along each of said shafts to grip said blocks in frictional engagement to prevent inadvertent rotational movement.
Claim 6
Dependent Claim
164 words
A game and display board mechanism comprising: an enclosed frame; a plurality of shaft aligned parallel to each other and extending from a first to an opposite side of said frame; a plurality of blocks mounted for rotational movement on each of said shafts; said blocks each having a plurality of exterior surfaces and weighted lobe located within each block to cause the display of a selected one of said exterior surfaces when said blocks are allowed to rotate freely on said shafts; spacer means located between adjacent blocks and extending between and surrounding at least two of said shafts; a biasing spring means for creating an axial load along each of said shafts to grip said spacer means and said blocks in frictional engagement to prevent inadvertent rotational movement of said blocks; and reset means for relieving said axial load to allow each of said blocks to rotate under action of its weighted lobe to display said selected one of said exterior surfaces.
Claim 7
Dependent Claim
164 words
A game and display board mechanism comprising: an enclosed frame; a plurality of shaft aligned parallel to each other and extending from a first to an opposite side of said frame; a plurality of blocks mounted for rotational movement on each of said shafts; said blocks each having a plurality of exterior surfaces and weighted lobe located within each block to cause the display of a selected one of said exterior surfaces when said blocks are allowed to rotate freely on said shafts; spacer means located between adjacent blocks and extending between and surrounding at least two of said shafts; a biasing spring means for creating an axial load along each of said shafts to grip said spacer means and said blocks in frictional engagement to prevent inadvertent rotational movement of said blocks; and reset means for relieving said axial load to allow each of said blocks to rotate under action of its weighted lobe to display said selected one of said exterior surfaces.
Claim 8
Dependent Claim
34 words
The mechanism of claim 5 wherein each of said blocks is generally triangular in shape and has three exterior surfaces, and said weighted lobe is located opposite said selected one of said exterior surfaces.
Claim 9
Dependent Claim
45 words
The mechanism of claim 5 wherein each of said blocks comprises two outwardly extending oppositely disposed bosses surrounding the shaft in which the block is mounted; each of said bosses being in frictional contact with said spacer means under the influence of said axial load.
Claim 10
Dependent Claim
42 words
The mechanism of claim 5 wherein each of said spacer means comprises two bosses, each surrounding a different one of said shafts and each being in frictional contact with at least one of said blocks under the influence of said axial load.
