Abstract

A jigsaw puzzle toy has a board (2) with a recess (5) defined in its upper surface. The jigsaw puzzle toy includes a plurality of first projections (19) projecting on the upper surface of the board and having first shapes, respectively, when viewed in plan, a plurality of first blocks (23) having respective holes (31) defined in surfaces thereof and having respective shapes complementary to the first shapes of the first projections (19) for fitting engagement therewith, and respective cavities (29) defined in other surfaces thereof and having respective second shapes, respectively, when viewed in plan; and a plurality of second blocks (37) having respective shapes complementary to the second shapes, respectively, when viewed in plan, for fitting engagement in the cavities (29), respectively, of the first blocks. The second blocks (37) have respective second projections (39) having the first shapes, respectively. The first projections (19) are vertically movable downwardly, and positioned above sound generating units (50, 60) that produce sounds when the first projections (19) are moved downwardly. The first blocks (23) can be fitted in the recess (5) of the board (2).

Claims

1. A jigsaw puzzle toy comprising:

a board;

a plurality of first projections projecting on an upper surface of said board and having first shapes, when viewed in plan;

a plurality of first blocks having first holes defined in surfaces thereof and having shapes complementary to said first shapes of said first projections for fitting engagement therewith, and second holes defined in other surfaces thereof different from said first holes when viewed in plan; and

a plurality of second blocks having shapes complementary to said second shapes, when viewed in plan, for fitting engagement in said cavities, of said first blocks.

2. A jigsaw puzzle toy according to claim 1, wherein said second blocks have second projections having said first shapes.

3. A jigsaw puzzle toy according to claim 1, wherein each of said first blocks has, on a side thereof, at least one of a tooth or a recess, which is engageable with one of the tooth and the recess of another one of the first blocks.

4. A jigsaw puzzle toy according to claim 1, further including resilient members supporting said first projections, for allowing the first projections to be depressed vertically against the resilient members.

5. A jigsaw puzzle toy according to claim 4, further including sound generating means, disposed below said first projections, for generating sounds in response to the depression of said first projections.

6. A jigsaw puzzle toy according to claim 5, wherein said sound generating means comprise means for generating sounds corresponding to the shapes of said second blocks.

7. A jigsaw puzzle toy according to claim 1, wherein said board has a recess defined in an upper surface thereof, for allowing said first blocks to be fitted therein, said first projections being disposed in a bottom of said recess.

8. A jigsaw puzzle comprising

a board with a first set of upward projections,

a first set of blocks having on a surface recesses complementary to said first set of upward projections and having a second set of upward projections on a surface opposed to said surface with recesses,

a platform having holes complementary in shape to the second set of upward projections on said first set of blocks,

said second set of upward projections on said first set of blocks extending through their complementary holes in said platform.

9. A jigsaw puzzle according to claim 8 further comprising

a second set of blocks having recesses in one surface thereof complementary to the upward projections of said first set of blocks.

10. A jigsaw puzzle according to claim 9 wherein said one surface of said second set of blocks have interfitting projections parallel to the plane in which said recesses are formed.

11. A jigsaw puzzle according to claim 10 wherein

said second set of blocks have recesses in a surface opposed to said one surface, and

a third set of blocks having shapes complementary to said last mentioned recesses.
