FLEXIBLE CONNECTORThe present application contains the disclosure of a provisional application entitled “Flexible Structural Connector” filed on or about May 28, 2004.background OF THE INVENTIONOBJECTS OF THE INVENTIONSUMMARYIn summary, however, the invention embraces in a flexible construction set, a longitudinally extending flexible connector strip formed as a linkage of successively connected transverse holes serving as connector nodes for receiving respective structural elements transversely press-fitted into the corresponding holes for node-connection thereat.In the previously described use of the invention as a toy for use with foam tubes, popularly known as “noodles” and which are commonly used at swimming pools, the longitudinal connector strip is preferably made from flexible foam, similar to that used for the noodles, and is configured as a long member with a pattern of successive transverse holes, each of which is made slightly smaller than the diameter of the typical noodle. The connector strip, as earlier mentioned, can also be made from flexible plastic or rubber, but foam ensures that it will float and that it is also soft so that if swung or thrown, it will not cause injury. The holes are sized so that each noodle element pressed into a connector hole can serve as a structural node. Since the connector strip is made from foam, or other flexible material, moreover, it can be bent and twisted, thereby enabling it to assume complex-shapes such that many noodles can be inserted and used in conjunction with other connector links to build complex structures. Because the connector and the noodles are flexible, moreover, together they have immense play value because users are not limited by fixed angles and rigid members, and indeed, because the elements are flexible, users may learn how to achieve proper diagonal bracing in order to provide stability to the structures. When made from a resilient material such as rubber, the connector can accommodate hard structural members, such as plastic pipe, as before mentioned, to rapidly create emergency structures.1. In a flexible construction set, a longitudinally extending flexible connector strip formed as a linkage of successively connected transverse holes serving as connector nodes for receiving respective structural elements transversely press-fitted into the corresponding holes for node-connection thereat.AbstractA structural connection device to be used primarily as a toy in conjunction with foam tubes, popularly known as “noodles” which are commonly used at swimming pools, wherein the connector is preferably made from foam and is configured as a longitudinal flexible member with a pattern of holes, each of which is slightly smaller than the diameter of a typical noodle, such that a noodle can be press-fit into a connector strip hole to act as a structural node; and because the connector may be made from foam, particularly for toy use, it can be bent and twisted, therefore enabling one simple element to act as a complex-shaped node into which many noodles can be inserted and used in conjunction with other connectors to build complex structures. Because the connector and the noodles are flexible, together they have immense play value because users are not limited by fixed angles and rigid members; and, indeed, because the elements are flexible, users learn to use proper diagonal bracing methods in order to provide stability to the structures. When made from a resilient material such as rubber, the connector can also be used with hard structural members, such as plastic pipe, to rapidly construct emergency structures.FLEXIBLE CONNECTORThe present application contains the disclosure of a provisional applicationentitled “Flexible Structural Connector” filed on or about May 28, 2004..STATEMENT REGARDING FEDERALLY FUNDED RESEARCHNo federal funds were used in the development of this inventionFIELD OF THE INVENTIONThe present invention relates to flexible structural connectors to enable thecreation of truss-type structures, but more particularly, but not exclusively, to the creationof toy structures. Although the first preferred embodiment uses foam as the materialfrom which the connector to join other foam components such as “noodles” used inswimming pools, a rubber version, for example, would enable the connector to be usedwith hard “real” structural elements such as plastic pipe to enable the rapid constructionof structures such as might be used for emergency construction.BACKGROUND OF THE INVENTIONThere are a great many toy construction sets on the market and a great many toyswhich are based on the theme of construction sets. Most construction sets have beenmade out of dense and hard materials, and do not enable flexile free-form connections.Even the prior foam connectors sold for toy “noodles”, or the connectors of the typedescribed in our earlier US patent 6,641,453, while extremely useful, are, however,1limited to intersections at fixed rigid angles, relying on the flexibility of the noodles toachieve non-standard angles. This can limit the toy-play experience by the users. US Patent 5,498,190 describes a toy for making sculptures where foam blockswith holes can be used as connectors for other foam structures with wire cores; however,it is not suited for use as a structural connection system that join many structural elementsat a node to form a truss-type structure.There are, moreover, a vast plethora of node constructions that have beendesigned for building construction systems, such as for modular trusses; but, they alsoappear to focus on fixed and/or rigid angle designs.The technique and designs of this invention, on the other hand, readily and simplyovercome these limitations both in the area of toys and in the more general areas ofconstruction structures. They preferably involve the use of plastic foam, rubber or otherflexible and resilient material for supporting transversely extending noodles or otherconstruction elements, that may also be flexible as of foam for toys or more structural asof PVC pipe where appropriate. This allows the noodles or other structural elements tobe detachably pressed into the connectors, with the connectors themselves being locallyvery flexible in bending, yet relatively strong in shear. The effect therefore is somewhatakin to lashing poles
