Abstract
A sorting device including an open top container with an invertible sorting member mounted thereover. The sorting member includes multiple funnel-shaped passages therethrough each having, at one end, an enlarged opening and at the second truncated end a specifically configured opening of a size to closely receive and pass therethrough only a correspondingly configured block introduced in either direction through the configured opening.
Claims18
A shape sorting device comprising an invertible sorting member and individual differently configured blocks, said sorting member having opposed spaced first and second surfaces, a plurality of passages transversely between said surfaces, said passages each having a first opening and a corresponding second opening respectively at and through said first and second surfaces, said second openings at said second surface being of different specific configurations corresponding to the differently configured blocks to accommodate only the correspondingly configured block therethrough, said first openings through said first surface each being substantially larger than said corresponding second openings through said second surface and of a size and shape to receive all of said blocks therethrough, each passage tapering from its first opening to its second opening whereby a corresponding block introduced through said first opening is guided to and through said second opening, support means for supporting said sorting member and for selectively positioning said first surface and said second surface outermost for selective introduction of said blocks either initially through said larger first openings for guided movement through said configured second openings from said first surface or initially through said second openings from said second surface.
An educational toy comprising a container with an opening therein, an invertible sorting member positionable on said container across said opening, said sorting member including opposed spaced generally parallel first and second surfaces, means for securing said sorting member to said container with each of said surfaces selectively uppermost by an inverting of said sorting member, said sorting member having a plurality of passages therethrough between said surfaces, a first opening from each passage through said first surface and a second opening from each passage through said second surface, each of said second openings having a specific configuration differing from the configurations of the remaining second openings, a separate block corresponding to each second opening and configured for close tolerance fitting through said corresponding second opening, said second openings and corresponding blocks being configured to allow passage of only a block of corresponding configuration through each second opening, said first openings of said passages each being substantially larger than said corresponding second opening and allowing passage of blocks configured for close tolerance fitting through each of said second openings, each passage tapering from its larger first opening to its configured second opening, each block being selectively introducible through its corresponding second opening from both said first surface and said second surface with introduction of said block through said first surface utilizing the corresponding tapered passage as guide means for movement of the block toward the corresponding second opening.
An educational toy comprising a receptacle with an opening therein, a sorting member positionable on said receptacle across said opening, said sorting member including opposed spaced generally parallel first and second surfaces, said sorting member having a plurality of passages therethrough between said surfaces, a first opening from each passage through said first surface and a second opening from each passage through said second surface, each of said second openings having a specific configuration differing from the configurations of the remaining second openings, a separate block corresponding to each second opening and configured for close tolerance fitting through said corresponding second opening, said second openings and corresponding blocks being configured to allow passage of only a block of corresponding configuration through each second opening, said first openings of said passages each being substantially larger than said corresponding second opening and allowing passage of blocks configured for close tolerance fitting through each of said second openings, each passage tapering from its larger first opening to its configured second opening, each second opening being visible through the associated first opening, each block being selectively introduced through its corresponding second opening from said first surface with introduction of said block through said first surface utilizing the corresponding tapered passage as guide means for movement of the block toward the corresponding second opening.
