Abstract
An inflatable building block is formed of an air impermeable flexible envelope forming a rectangular polyhedron, a valve for regulating flow of air into and out of the air impermeable flexible envelope, and connectors on at least two opposed sides of the rectangular polyhedron for connecting the inflatable building block to another inflatable building block. Opposed sides of the rectangular polyhedron are internally connected to each other by connecting members that limit movement of the rectangular sides away from each other. The connecting members are preferably flexible membranes that connect to the rectangular sides along lines that bisect the rectangular sides, and which, upon inflation of the inflatable building block, the connecting lines between the membranes and the rectangular sides lie in the faces of the rectangular polyhedron formed by the inflatable building block. The connectors may be of the hook and loop type. The inflatable building blocks are preferably used in sets, some of the building blocks being cubes, and some rectangular polyhedrons with two opposed sides matching the sides of the cubes.

TITLE OF T~E INVENTION:
Inflatable Building Blocks NAME(S) OF INVENTOR(S):
Dennis Siteman FIELD OF THE INVENTION
This invention relates to construction toys.
BACRGROUND AND SUMMARY OF THE INVENTION
Various kinds of building blocks are known, but this invention provide~ a previously unknown, lightweight, inflatable construction toy capable of making a diverse range of structures, yet easily put away for storage.
There is therefore provided in accordance with one aspect of the invention, an inflatable building block, comprising an air impermeable flexible envelope forming a rectangular polyhedron, a valve for regulating flow of air into and out of the air impermeable flexible envelope, and connectors on at least two opposed sides of the rectangular polyhedron for connecting the inflatable building block to another inflatable building block.
In accordance with a further aspect of the invention, opposed sides of the rectangular polyhedron are internally connected to each other by connecting members that limit movement of the rectangular sides away from each other. The connecting members are preferably flexible membranes that connect to the rectangular sides along lines that bisect the rectangular sides. Upon inflation of the inflatable building block, the connecting lines between the membranes and the rectangular sides lie in the faces of the rectangular polyhedron formed by the inflatable building block .
In accordance with another aspect of the invention, the connectors may be of the hook and loop type.
The inflatable building blocks are preferably used in sets, some of the building blocks being cubes, and 5some rectangular polyhedrons with two opposed sides matching the sides of the cubes.
Further aspects, features and advantages of the invention appear in the description and claims that follow.
There will now be described preferred embodiments of the invention, with reference to the drawings, by way of illustration, in which like numerals denote like elements and in which:
15Fig. 1 is a perspective view, partly cut away, of a first embodiment of a building block according to the invention;
Fig. 2 is a perspective view of the building block of Fig. 1;
20Figs. 3, 4 and 5 are each side views of different sides of the building block of Fig. 1;
Fig. 6 is a perspective view of a second embodiment of a building block according to the invention;
and 25Fig. 7 is a side view of the building block of Fig. 6.
DE~ATT-~n n~-~CPTPTION OF l~rrnnrv EMBODIMENTS
The inflatable building block of Figs. 1-5 forms 30a cube, with three pairs of square opposed sides, while the inflatable building block of Figs. 6 and 7 forms a rectangular polyhedron with a pair of square end faces. The inflatable building block of the invention may also form a rectangular polyhedron with each pair of opposed rectangular sides having a different shape, with the limitation that the sides must fit together. With rectangular sides of at least one of the pairs of rectangular sides being square the inflatable building block may more readily be fitted with other inflatable building blocks of similar construction.
The inflatable building block according to the invention is formed of an air impermeable flexible envelope 10 forming a rectangular polyhedron having three pairs of opposed rectangular sides 12A, 12B, 14A, 14B, 16A and 16B.
Edges between the sides may be formed by creasing of the material of the envelope. The inflated structure, without the internal connecting members described below, forms an approximately rectangular polyhedron with bulging sides.
The use of the internal connecting membranes allows the inflated envelope to more closely approximate a rectangular polyhedron and allows the blocks to sit on top of each other with some degree of stability.
A conventional valve 18 on one of the rectangular sides, for example 14A as shown, regulates flow of air into and out of the air impermeable flexible envelope 10. The valve 18 should be of the type that may be blown into by a person to inflate the inflatable building block, and should preferably include a conventional flap to help prevent air escaping the envelope 10 except when the valve 18 is squeezed. The envelope 10 should be made of a lightweight flexible polymer such as is conventionally used in blow up toys (for example, beach balls).
A connector 22, preferably a loop connector of a hook and loop type connector, such as Vecro~, is attached, as by gluing, on one of the rectangular sides 12A, of the first pair of opposed rectangular sides 12A, 12B, for connecting the inflatable building block to another inflatable building block. Another connector 24, preferably a hook connector of a hook and loop type connector, such as Velcro~, is attached, as by gluing, on the other rectangular side 12B, of the first pair of opposed rectangular sides 12A, 12B, for connecting the inflatable building block to another inflatable building block.
Connectors of the hook and loop type may also be adhered to others of the pairs of opposed rectangular sides. The connectors 22, 24 are preferably strips adhered in pairs to the sides of the inflatable building block, symmetrically placed on either side of lines 30 dividing the opposed rectangular sides 12A and 12B.
With hook and loop connectors 22 and 24, each inflatable building block 10 may be connected to any other inflatable building block of similar construction. At least some of the inflatable building blocks in a set of inflatable building blocks should be cubes and at least some should be rectangular, with one square pair of opposed rectangular sides having about the same size as the sides of the cubes. This helps in fitting the inflatable building blocks together. The building blocks have a size suitable for manipulation by a child, and should be large enough, for example with the smallest side being about 20 cm long, that it does not take many of the building blocks (say 6 or so) to make a construction assembly large enough to fit a child.
As shown in Fig. 1, the rectangular sides of each pair of opposed rectangular sides 12A, 12B, 14A, 14B, 16A
and 16B are internally connected to each other by connecting members 26 and 28 that limit movement of the rectangular sides away from each other. The connecting members 26 and 28 should be made of the same lightweight flexible polymer as the envelope 10.
Conceivably, the connecting member8 26 and 28 could be formed of filaments that connect to any part of the opposed rectangular sides, but it is preferred that the resulting inflatable building blocks be symmetrical, and thus it is preferred that the connecting members 26 and 28 connect to the sides 12A, 12B, 14A, 14B, 16A and 16B along lines 30, 32 and 34 that bisect the respective sides. In addition, it is preferred that the connecting members 26, 28 form flexible membranes as shown, rather than be formed of filaments, since these are easier to make and are more robust. Upon inflation of the inflatable building blocks.
the connecting lines 30, 32 and 34 between the membranes 26, 28 and the rectangular sides lie in the faces of the rectangular polyhedron formed by the inflatable building block.
Preferably, the flexible membrane 26 connects the rectangular sides of both the first and second pairs of opposed rectangular sides 12A, 12B, 14A and 14B, while the second flexible membrane 28 connects the rectangular sides of the third pair of rectangular sides 16A, 16B.
The rectangular building block 40 of Figs. 6 and 7, with one pair of square opposed sides 42A, 42B, has two pairs of opposed rectangular sides 44A, 44B, 46A and 46B.
The rectangular building block 40 iS made in the same manner as building block 10, except two of the pairs of opposed rectangular sides are elongated. The building block 40 also includes internal membranes (not shown) connecting to the envelope along lines 50, 51, 52 that bisect the respective sides to which they are joined. Rectangular sides 44A and 44B may have loop connectors 54 in the form of strips and hook connectors 56 in the form of complementary strips respectively running in pairs along most of the length of the sides 44A and 44B on either side of the bisecting lines 50. The length of the connectors should be enough to provide a firm lock between adjacent building blocks.
2t 72222 The inflatable building block may be formed by conventional plastic manufacturing techniques.
Construction assemblies are formed by connecting numerous of the inflatable building blocks 10, 40 together using the connectors 22, 24, 54 and 56.
The inflatable building blocks of the invention may be used in association with accessories, such as a rectangular plastic sheet with fitted edges. The plastic sheet may then be used as a roof for a building made of the inflatable building blocks.
A person skilled in the art could make immaterial modifications to the invention described in this patent document without departing from the essence of the invention that is intended to be covered by the scope of the claims that follow.
