[00034] The present invention is specific to interlocking swim noodles. More specifically, the present invention is related to swim noodles with alcoves and node components parallel to the long axis of the swim noodle wherein the alcoves and node components can be interlocked to form closed cell foam structure for water play or they can engage with connectors. Even more specifically, cross-brace components and connectors are provided which interlink to interlocking swim noodles thereby allowing for the formation of closed cell foam structures for water play.

[00035] The invention will be described with reference to the figures which form an integral part of the invention. Throughout the specification similar elements will be numbered accordingly.

[00036] An embodiment of the invention is illustrated in Fig. 1. In Fig. 1 , an interlocking swim noodle, 0, is illustrated in schematic perspective view. The interlocking swim noodle comprises nodes, 12 and alcoves, 14, arranged around a central core, 16. The nodes extend from the core and diverge outwardly from the core and the alcoves converge outwardly from the core such that in one embodiment when a node is inserted into an alcove an interference fit is achieved. In one embodiment the nodes and alcoves are arcuate, preferably with a variable arc, and in one embodiment the nodes and alcoves are a portion of an obround. It would be apparent that the nodes and alcoves are sufficiently pliable to be distortable to the degree necessary to interlock, and be separated, yet return towards relaxed state to form an interlocking interference fit when joined.

[00037] An embodiment of the invention is illustrated in schematic end view in Fig. 2 wherein two interlocking swim noodles are engaged with a node, 12, of one interlocking swim noodle, 10, engaged with an alcove, 14', of a second interlocking swim noodle, 0', thereby securing the first core, 16, and second core, 16', in relatively fixed side-by-side and parallel position. While illustrated with only two interlocking swim noodles engaged any number of interlocking noodles can be engaged to form various configurations including being arranged in a common plane, wherein interlocking swim noodles are interlocked on opposite sides of at least one interlocking swim noodle there between, or at angles, wherein interlocking swim noodles are interlocked with at least one interlocking swim noodle there between at an acute, right or obtuse angle.

[00038] An embodiment of the invention is illustrated in schematic side view in Fig. 3. In Fig. 3, an interlocking swim noodle, 10, with nodes, 12, and alcoves, 14, is interlocked with a cross-brace, 18, comprising cross-brace alcoves, 22, and islands, 20. In one embodiment the islands have a width, measured between alcoves, such that adjacent interlocking swim noodles will be in close proximity and preferably in physical contact. As illustrated the node, 12', is inserted into crossbrace alcove, 22'.

[00039] An embodiment of the invention is illustrated in schematic end view in Fig. 4. In Fig. 4, the nodes, 24, and alcoves, 26, are trapezoidally shaped thereby allowing for an interference fit when a node of one interlocking swim noodle is inserted into an alcove of the same or an adjacent interlocking swim noodle. The alcoves and nodes are arranged around a central core, 25.

[00040] An embodiment of the invention is illustrated in schematic end view in Fig. 5. In Fig. 5 a cross-brace, 28, comprising trapezoidally shaped nodes, 30, and alcoves, 32, is provided which allows for the parallel arrangement of interlocking swim noodles in a manner analogous to the embodiment illustrated in Fig. 3.

[00041] Embodiments of the invention are illustrated in end view in Figs. 6 and 8. Fig. 6 illustrates an interlocking swim noodle with five (5) nodes, 34, and five (5) alcoves, 36, around a central core, 38. Fig. 8 illustrates an interlocking swim noodle with six (6) nodes, 40, and six (6) alcoves, 42, around a central core, 44.

[00042] An embodiment of the invention is illustrated in schematic side view in Fig. 7. In Fig. 7 a cross-brace, 62, is illustrated with at least one node, 62, thereon for inserting in an alcove of an interlocking swim noodle.

[00043] An embodiment of the invention is illustrated in schematic perspective view in Fig. 9. In Fig. 9, a first interlocking swim noodle, 46, and a second interlocking swim noodle, 48, are interlocked with a cross-brace, 50, wherein nodes of each interlocking swim noodle is inserted into an alcove of the cross-brace. The cross-brace comprises nodes on opposing faces thereby allowing multiple interlocking swim noodles to be arranged on a common face or on opposing faces of the cross-brace. One of skill in the art would immediately realize the large number of available configurations and arrangements provided by the combination of cross-braces and interlocking swim noodles.

[00044] An embodiment of the invention is illustrated in schematic perspective view in Fig. 10. In Fig. 10, the interlocking swim noodle, 52, comprises mating nodes, 54, and alcoves, 56, around a central core, 58. The core has a void located therein and, preferably, extending the length of the interlocking swim noodle. In one embodiment the void increases yieldability of the nodes and alcoves to facilitate insertion of the node into the alcove. In another embodiment the void minimizes material use for economic efficiency. In yet another embodiment the void allows for additional functionality as will be realized from the description herein.

[00045] An embodiment of a connector for interlocking swim noodles is illustrated in perspective isolated view in Fig. 1 1 and schematic perspective view as used with an interlocking swim noodle in Fig. 12. An insert, 1100, comprising a tube engagement portion, 1 02, is engaged with the interlocking swim noodle, 1 101. The tube engagement portion is preferably conical shaped and more preferably barbed or threaded to provide a friction fit within the void of the central core of the interlocking swim noodle. Opposite the tube engagement portion on the insert is a joint member engagement portion, 1 104, which is received by a joint member, 1 106, as more readily visualized in Fig. 13. In one embodiment the insert has a centrally located collar, 1107, which restricts how far the insert can be inserted into either the interlocking swim noodle or the joint member. The joint may be pierced by the joint member engagement portion thereby forming a void which may be permanent or may at least partially close by material migration.

[00046] Multiple interlocking swim noodles, each with at least one connector, may be connected to a common joint member thereby allowing many configurations of joined interlocking swim noodles. Figs. 14 and 15, for example, illustrate an orientation wherein multiple interlocking swim noodles are at an angle which can be acute, obtuse, a right angle or parallel. Each interlocking swim noodle may be separately engaged with an additional interlocking swim noodle in any manner otherwise described herein.

[00047] A particularly preferred connector is a T-connector with an exemplary T-connector provided in Fig. 16. The connector, generally

represented at 3000, comprises a tube engagement portion, 3002, which may be barbed or threaded with threaded being preferred. The tube engagement portion is preferably sized to be received by a void of the central core as described herein. The connector is rotated such that the threads draw an alcove insert, 3004, towards the interlocking swim noodle as will be more readily appreciated from further description. The alcove insert, which is preferably integral to the connector, is preferably asymmetrically shaped with a shorter cross-section, S, which is preferably no wider than the opening of the alcove, and a long cross- section, L, which is preferably sufficiently long to lock within the alcove when the long cross-section is perpendicular to the axis of the interlocking swim noodle. To join the interlocking swim noodles the tube engagement portion can be inserted into the void of one interlocking swim noodle and the alcove insert can be oriented such that the long cross-section is parallel to the axis of the interlocking swim noodle and then rotated relative thereto such that the alcove insert wedges into the alcove. Optional, but preferred threads, 3006, can breach the surface of the alcove to provide additional strength. The alcove insert may comprise a channel, 3008, which receives the node.

[00048] A connector which is at least partially hollow is illustrated in Fig. 17. [00049] An interlocking swim noodle, 3100, is illustrated in Fig. 18 with the alcove insert engaged with the alcove, 3102.

[00050] The interlocking swim noodle, 3100, of Fig. 18 is illustrated in Fig. 19 wherein the tube engagement portion is engaged with the void of a second interlocking swim noodle, 3100', and is therefore obscured from view. The tube engagement portion of a second connector is engaged with the void of

interlocking swim noodle, 3100. One of skill in the art would immediately appreciate the large number of configurations available by the creative

combination of connectors and interlocking swim noodles.

[00051] An embodiment of the connector is illustrated in Figs. 20 and 21 wherein a first connector, 3200, comprises a locking mechanism, 3202, which is received by a locking component, 3404, of a second connector, 3406. This allows two connectors to be connected with the tube engagement portions, 3008, opposite to each other such that two interlocking swim noodles can be connected in an end to end configuration thereby allowing for networks of interlocking swim noodles to be formed as illustrated in isolated view in Fig. 22 and as assembled in Fig. 23.

[00052] An embodiment of the invention is illustrated in Fig. 24 wherein a connector is fitted with a hose adaptor, 3300, thereby allowing water to flow through passages, 3302, wherein water can pass through the void thereby forming a water cannon for additional water activities.

[00053] An embodiment of the invention is illustrated in Fig. 26 wherein multiple interlocking swim noodles are interlocked in parallel fashion for the purposes of illustration. A linear reinforcement, 4002, is inserted at least partially into the void for bending resistance or for shape retention. An optional, but preferred connector, 4006, either attached to or integral to the linear

reinforcement allows other interlocking swim noodles, 4004, or additional functionality to be included.

[00054] The length of the interlocking swim noodle is selected to be of sufficient length to be easily grasped by the hand yet sufficiently short to be easily manipulated. It is preferable that the interlocking swim noodle be at least about 12 inches long to no more than about 6 ft. Below about 12 inches the buoyancy is insufficient to be of interest when used singularly and above about 6 ft in length the interlocking swim noodle is unwieldy in transport and storage. A length of about 3 ft. to about 4 ft. is optimum.

[00055] The longest cross-sectional length of the interlocking swim noodle, L in Fig. 10, is sufficiently large to provide nodes with a sufficient strength for interlocking without damage. The longest cross-sectional length is sufficiently small to be easily grasped by the hand of a child or adult of average size. Below a longest cross-sectional length of about 2 inches the nodes have insufficient strength. Above a longest cross-sectional length of about 6 inches the diameter prohibits the interlocking swim noodle from being easily grasped, particularly, by a child.

[00056] The interlocking swim noodles and cross-braces are preferably a material with a density which is lower than water. The density is preferably at least about .4 to 2.6 pounds per cubic foot and more preferably about 1.8 to about 2.0 pounds per cubic foot since this provides a particularly suitable buoyancy for use as a flotation toy. Synthetic resin materials, such as extruded cellular polyethylene, are exemplary for demonstration of the teachings herein as are other materials which are shape retaining and yieldable. Close cell structures are highly preferably over open cell structures as is a material which is biocompatible with swimming environments.

[00057] The invention has been described with reference to the preferred embodiments without limit thereto. One of skill in the art would readily appreciate and realize additional embodiments and improvements which are not specifically stated but which are within the scope of the invention as more specifically set forth in the claims appended hereto.
