Abstract
Abstract A mosaic play of the type comprising a base plate with holes and a number of mosaic elements intended to be inserted in the holes of the base plate, wherein the base plate comprises a number of plate elements. Each plate element is made of slightly flexible synthetic material and its sides are indented in the form of castellations for allowing connection with adjacent plate elements, so that base plates of any shape and size may be formed by mutually joining the plate elements shaped in this manner.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
A mosaic play including a plurality of plate elements, in each plate element a number of through holes regularly arranged in an orthogonal network, each plate element having peripheral sides indented in the shape of castellations forming a succession of alternate recesses and projections, said castellations having a half pitch equal to the pitch of said network of holes, each plate element having an upper plain portion wherein said holes are formed, and perpendicular ribs extending from said plain portion downward, said perpendicular ribs being locaTed at least along said peripheral indented sides, and said plain portion having a number of collars projecting downward, each collar surrounding a said hole, each collar further having a small projection directed toward the interior of said hole; and a plurality of mosaic elements, each mosaic element having a head and a single stem, the diameter of said stem being substantially equal to the diameter of said through holes in the plate elements, whereby the stem of each mosaic element may be inserted in any selected one of said holes, and is guided by said collar and is frictionally retained by said small projection.
Claim 2
Dependent Claim
190 words
A mosaic play including a plurality of plate elements, in each plate element a number of through holes regularly arranged in an orthogonal network, each plate element having peripheral sides indented in the shape of castellations forming a succession of alternate recesses and projections, said castellations having a half pitch equal to the pitch of said network of holes, each plate element having an upper plain portion wherein said holes are formed, and perpendicular ribs extending from said plain portion downward, said perpendicular ribs being locaTed at least along said peripheral indented sides, and said plain portion having a number of collars projecting downward, each collar surrounding a said hole, each collar further having a small projection directed toward the interior of said hole; and a plurality of mosaic elements, each mosaic element having a head and a single stem, the diameter of said stem being substantially equal to the diameter of said through holes in the plate elements, whereby the stem of each mosaic element may be inserted in any selected one of said holes, and is guided by said collar and is frictionally retained by said small projection.
Claim 3
Dependent Claim
25 words
A mosaic play as claimed in claim 1, said ribs forming an orthogonal network thereby to impart a cellular structure to each said plate element.
Claim 4
Dependent Claim
40 words
A mosaic play as claimed in claim 1, each said rib having a height, inclusive of the thickness of said plain portion, equal to the half pitch of the castellations and equal to the pitch of said network of holes.
Claim 5
Dependent Claim
29 words
A mosaic play as claimed in claim 1, said plate elements being made of a slightly flexible synthetic material and being obtained by high pressure die casting or injection.
