Abstract

A cylindrical slide puzzle system including a cylindrical member, such as an open cylinder, cup or mug, having a slide puzzle incorporated with an outer cylindrical surface thereof. The slide puzzle includes a plurality of slide puzzle elements or pieces which are preferably arranged to form three horizontal rows between the top and bottom edges of the open cylindrical member, cup or mug--this allows for better fit as the slide puzzle elements proximate both the top and bottom are firmly held in place along at lease one side surface and a better fit is assured between the puzzle pieces. A single jamb or vertical stop extending between the top and the bottom edges of the cylindrical member is also provided. A handle, if desired, may be attached to the jamb so as to convert the cylindrical member from a cup to a mug in the case where a solid bottom wall is provided. This jamb serves as part of the frame of the puzzle. In a second embodiment, the cylindrical member is equipped with mutual interengagement structure on the top and bottom edges, preferably matching male and female threads, so as to permit interconnection between respective upper and lower edges of adjacently stacked and similarly constructed cylindrical members. This permits one to create a larger and more complex cylindrical slide puzzle and/or hold a greater volume of material.

Claims18

Dependent claims

A cylindrical slide puzzle combination comprising:

an open cylindrical container member having an outer cylindrical wall with a lower edge and an upper edge;
an upper lip flange located proximate said upper edge and a base flange located proximate said lower edge;
a sliding element stop means comprising a generally rectangular surface extending between said upper edge and said lower edge and having a first puzzle retaining edge and a second puzzle retaining edge, said first and second puzzle retaining edges being distal from one another and the first puzzle retaining edge including a groove extending from said upper edge to said lower edge of said cylindrical wall and the second puzzle retaining edge including a ridge extending from said upper edge to said lower edge of said cylindrical wall, thus forming a jamb such that a sliding element puzzle frame is formed;
a plurality of sliding puzzle elements each having four edges, and each having a first groove defined in a first element edge, a first ridge formed on the element edge distal to said first element edge, a second groove defined in a second element edge, said second element edge being generally perpendicular to said first element edge, and a second ridge formed on the element edge distal to said second element edge;
and
mutually interengageable thread means located on said upper lip flange and said base flange, said interengageable thread means including a male and female portion and where said male portion is located proximate said base flange and said female portion is located proximate said upper lip flange such that a system of cylindrical container members may be mounted one atop the other, cooperatively engaging to form a larger cylindrical puzzle having a continuously smooth external cylindrical wall and an enlarged continuous container volume.

A cylindrical slide puzzle comprising:

an open cylindrical container member having an outer cylindrical wall with a lower edge and an upper edge;
an upper lip flange located proximate said upper edge and a base flange located proximate said lower edge;
a single vertical jamb extending between said upper edge and said lower edge and having a first puzzle retaining edge and a second puzzle retaining edge, said first and second puzzle retaining edges being distal from one another and the first puzzle retaining edge including a groove extending from said upper edge to said lower edge of said cylindrical wall and the second puzzle retaining edge including a ridge extending from said upper edge to said lower edge of said cylindrical wall;
a plurality of sliding puzzle elements each having four edges, and each having a first groove defined in a first element edge, a first ridge formed on the element edge distal to said first element edge, a second groove defined in a second element edge, said second element edge being generally perpendicular to said first element edge, and a second ridge formed on the element edge distal to said second element edge;
and
mutually interengageable thread means located on said upper lip flange and said base flange, said interengageable thread means including a male and female portion and where said male portion is located proximate said base flange and said female portion is located proximate said upper lip flange such that a system of similarly constructed cylindrical container members may be mounted one atop the other in cooperative engagement to form a larger cylindrical slide puzzle having a continuously smooth external cylindrical wall and an enlarged continuous container volume.

3 more elements

A cylindrical slide puzzle system comprising:

a) a plurality of open cylindrical container members, wherein each cylindrical container member includes:
i) an outer cylindrical wall with a lower edge and an upper edge;
ii) an upper lip flange located proximate said upper edge and a base flange located proximate said lower edge;
iii) a single vertical jamb extending between said upper edge and said lower edge and having a first puzzle retaining edge and a second puzzle retaining edge, said first and second puzzle retaining edges being distal from one another and the first puzzle retaining edge including a groove extending from said upper edge to said lower edge of said cylindrical wall and the second puzzle retaining edge including a ridge extending from said upper edge to said lower edge of said cylindrical wall;
iv) a plurality of sliding puzzle elements each having four edges, and each having a first groove defined in a first element edge, a first ridge formed on the element edge distal to said first element edge, a second groove defined in a second element edge, said second element edge being generally perpendicular to said first element edge, and a second ridge formed on the element edge distal to said second element edge;
and
b) each of said cylindrical container members includes interengagement means adapted to permit releasable engagement between respective upper lip and base flanges of two or more adjacently stacked cylindrical container members so as to form a larger cylindrical slide puzzle having a continuously smooth external cylindrical wall and an enlarged continuous container volume.
