Tumbler Die and Dice Having Changeable Faces

Abstract

A first and second die each have a plurality of flat side faces and a pair of flat end faces. Unique marking are provided on each face. A connector releasably interconnects the first and second dies. Relative rotation between the first and second dies increases the number of combinations of pair groupings or markings that may be provided by the side faces when the dice is rolled. In a second embodiment, a hollow die has a plurality of faces and a cut-out is formed in each face, producing a flat part for each cut-out. Each flat part is press-fittable into its associated cut-out and has two sides each of which bears a preselected marking. Each flat part is removably mounted within its associated cut-out so that either the first or second marking is displayed when the flat part is positioned within its cut-out.

1 . A pair of dice, comprising:
 a first die having a plurality of side faces, each of which is flat;   said first die further having a first pair of end faces, each of which is flat, said first pair of end faces including a first inboard end face and a first outboard end face;   said end faces of said first die having a geometrical configuration determined by the number of said side faces of said first die;   a second die having a plurality of side faces, each of which is flat;   said second die further having a second pair of end faces, each of which is flat, said second pair of end faces including a second inboard end face and a second outboard end face;   said end faces of said second die having a geometrical configuration determined by the number of said side faces of said second die;   each side face and each outboard end face of said first die and each side face and each outboard end face of said second die being provided with a preselected marking;   a connecting means for rotatably interconnecting said first and second dies to one another with said first and second inboard faces in confronting relation to one another so that relative rotation between said first and second die increases the number of combinations of markings that are provided by said side faces of said dice when said dice is rolled;   an outboard end face alone providing a preselected marking when said dice comes to rest on an outboard end face after being rolled.   
   
   
       2 . The dice of  claim 1 , further comprising:
 said connecting means including a pair of protuberances formed in an inboard end face of said first pair of end faces; and   said connecting means further including a pair of blind bores formed in an inboard end face of said second pair of end faces.   
   
   
       3 . The dice of  claim 1 , further comprising:
 said connecting means including a protuberance formed in an inboard end face of said first pair of end faces; and   said connecting means further including a blind bore formed in an inboard end face of said second pair of end faces, said blind bore adapted to snugly and roatably receive said protuberance so that said first and second die may be rotated relative to one another while coupled to one another.   
   
   
       4 . The dice of  claim 1 , further comprising:
 each die having at least three side faces.   
   
   
       5 . A die, comprising:
 a hollow die having a plurality of at least three faces;   a cut-out formed in each of said faces;   a flat part produced by each of said cut-outs;   each flat part being press-fittable into its associated cut-out;   each flat part having two sides;   a first preselected marking formed on a first side of said two sides and a second preselected marking formed on a second side of said two sides;   each flat part being removably mounted within its associated cut-out so that either said first or second preselected marking may be displayed when said flat part is positioned within its associated cut-out.   
   
   
       6 . The hollow die of  claim 5 , further comprising:
 each flat part having a main body of predetermined geometrical configuration and a pair of narrow arms;   a spherical member integrally formed with each of said narrow arms at their respective distal ends;   a circular cut-out formed in each face of said die, and each spherical member being snugly press fit into an associated circular cut-out.   
   
   
       7 . The die of  claim 6 , further comprising:
 each spherical member having a diameter slightly less than a thickness of the face within which it is formed so that the face lies on a flat surface without interference from said spherical member.
