in the following detailed descriptions of various embodiments , reference is made to the accompanying drawings that form a part hereof , and in which is shown , by way of illustration , specific embodiments that may be practiced . it is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present disclosure . fig1 is a perspective view of an embodiment constructible water toy 100 with a multitude of configurations . each configuration requires at least two components ; a beam 101 and a connector 102 , though other components may be contemplated and are contemplated later in the present disclosure . these components ( 101 , 102 ) may be sold in kits of parts to facilitate the construction of different structures . structure complexity is only limited by the number of components and the type of connectors , thus allowing the structure to take on a plurality of different forms . the beam 101 may be provided with different lengths such as 1 foot , 2 feet , 4 feet , and so forth . beam 101 lengths may also be non - integer fractions such as 2 feet 1⅝ inches and 4 feet 6 inches . additionally , beam 101 lengths may be computed using the pythagorean theorem in order to be provided with corner - to - corner spanning ability . for example , if two beams 101 that are each 4 feet in length are joined by a connector 102 having a 90 degree corner , then the corner - to - corner spanning beam 104 length must be the square root of 4 2 + 4 2 , which is approximately 5 feet 7⅞ inches . this corner - to - corner spanning beam 104 may also be referred to as a diagonal beam 104 . using this method , many permutations of lengths of beams 101 , 104 are contemplated which may be sold as a kit or individually , along with connectors 102 . referring to fig2 , a partial exploded perspective view of fig1 is shown . in an embodiment , the beam 101 and connector 102 may be joined with a connector link 103 ( also referred to as a “ connector adapter ”). the link 103 may incorporate nubs 105 that hold the beam 101 and the connector 102 firmly together upon assembly , but allow the components ( 101 , 102 , 103 ) to be removed upon squeezing , twisting , pulling , and so forth . the link 103 may simplify the manufacture of the beam 101 and / or the connector 102 because , for example , if nubs 105 were placed on the ends of the beam 101 then it may be difficult to insert the endoskeleton support 302 into the outer tubular member 301 ( each shown in fig3 ). furthermore , nubs 105 may be replaced with , or used in conjunction with , alternative forms of coupling such as pins , screws , tangs , and so forth . in an embodiment , the nubs 105 may be placed on the one or more ends of the connector 102 so that they may engage with an end of the beam 101 , thereby eliminating the need for a link 103 . in another embodiment , the structure 100 may loosely be coupled together without a nub 105 or other coupling feature , thereby making a structure 100 held together via a friction fit where the parts fit snugly together and are restricted from movement . a friction fit may be accomplished used a tapered bore and tapered shaft combination , close - tolerance bore and shaft combination , and so forth . fig3 is a perspective view , end view , and cross - section of an embodiment constructible water toy beam 101 . the beam 101 may consist of an inner endoskeleton support 302 and an outer tubular member 301 . the inner support 302 may be a tube , bar , or rod that has a cross - sectional shape that may conform to the inside diameter of the outer tubular member 301 . the inner support 302 may be made of a material suitable for structural support yet lightweight enough for a toy that can be easily manipulated and float on water . high corrosion resistance may also be a concern due to its use in water . such materials may be wood , fiberglass , polyvinylchloride ( pvc ), plastic , aluminum and so forth . the inner support 302 may be fabricated and then inserted from an end of the outer tubular member 301 , and then pushed through the hollow center cavity with the support 302 ends evenly protruding beyond the tubular member 301 ends . alternatively , the inner support 302 may be placed into an injection mold , and then have foam injected thereby surrounding and solidifying to create an outer tubular member 301 with an endoskeleton support 302 . the tubular member 301 may be made from polyethylene foam , similar in characteristic to a pool noodle , water log , woggle , or the like . however , different foams may be employed to achieve different desired effects . polystyrene , polyurethane , extruded polystyrene foam ( xps ), and so forth may be used in addition to polyethylene which may have different densities by varying the size of the cells , or bubbles , in the foam . foam density and / or material may be adjusted to increase or decrease buoyancy , hardness , stiffness , color , and so forth . in an embodiment , the ends of the inner support 302 may have at least one hole 303 to engage a pin , screw , tang , nub , or the like in the connector 102 or the connector link 103 . a hole 303 may be inserted radially and extend through either one or both walls of the tubular member 301 . the hole 303 may be circular , square , trapezoidal , and so forth to allow easy insertion or removal of the connector 102 or connector link 103 . the hole 303 may be placed sufficiently from the support 302 end to maximize strength and minimize insertion depth . in another embodiment , the center of the hole 303 may be located 0 . 50 inches from the end of the support 302 . fig4 is a perspective view , end view , and cross - section of another embodiment constructible water toy beam 400 , which is similar to beam 101 . the inner support 402 may not traverse the entire length of the beam 400 . an inner support 402 may be inserted into an end or ends of the outer member 401 , which may require the outer member 401 to provide the primary structural support for the beam 400 . alternatively , it may be advantageous to maintain flexibility in the outer member 401 to yield further variety in creating structures with rounded features such as domes , cones , cylinders , spheres , and so forth . as in other embodiments described herein , the outer member 401 may be made from polyethylene foam . the foam may be tinted with various colors for variety , or the foam may be tinted to designate different characteristics such as rigidity or hardness . for example , if a beam 400 were colored red , then it may be used as a stiff , straight structural element . whereas , if the beam 400 were colored green , then it may be flexible in order to form a rounded structure . in an embodiment , the inner support 402 may comprise a barb 403 or other such retaining structure or device in order to prevent easy removal of the inner support 402 from the outer member 401 . other shapes of the barb 403 are contemplated than what is shown in fig4 to effectuate a robust retention structure or device , including , but not limited to , a plurality of hooks or a triangular annulus . as noted above , the inner support 402 may be inserted into the ends of the outer member 401 , or the outer member 401 may be formed around the inner support 402 such as through an injection mold process . as in beam 101 , the ends of the support 402 may evenly protrude beyond the ends of the outer member 401 . an end cap 404 may be advantageous to facilitate the injection mold process by disallowing the foam into the inner cavity of the inner support 402 . additionally , the end cap 404 may be rounded or pointed to facilitate insertion of the inner support 402 into an end of the outer member 401 . fig5 is an end view and cross - section of still another embodiment constructible water toy beam 500 , which is similar to beam 101 . an endoskeleton support 502 is disposed within a soft outer member 501 . the outer member 501 may be identical in all respects to a traditional pool noodle , which may be a polyethylene foam round tube with a hollow , axial center cavity . the endoskeleton support 502 may be a hollow tube to save weight , save material , and so forth . as in other embodiments described herein , the ends of the support 502 may evenly protrude beyond the ends of the outer member 501 . fig6 is a perspective view , right side view , and front view of an embodiment constructible water toy connector 102 . the connector 102 is illustrated with three couplers 602 for receiving three beams 101 or three connecting links 103 . however , a connector 102 may have many different coupler 602 permutations including 1 through n couplers . additionally , the angle between each of the couplers 602 is not restricted to 90 degrees , and may be greater than or less than 90 degrees . one such use for a connector 102 with a coupler 602 angled other than 90 degrees may be to create a roof apex . couplers 602 may be made of a material suitable for structural support yet lightweight enough for a toy that can be easily manipulated and float on water . such materials may be wood , fiberglass , polyvinylchloride ( pvc ), plastic , aluminum , and so forth . in an embodiment , the connector 102 may be at least partially surrounded with a protector 601 made of polyethylene foam or similar material . in addition to cushioning for safety reasons , the protector 601 may provide additional buoyancy for the connector 102 , and / or aesthetic appeal . in another embodiment , the connector may have central bores 604 placed in the couplers 602 . with a hollow center , the coupler 602 may engage the end of the beam 101 or the link 103 by sliding over the outside of the coupler 602 . alternatively , the coupler 602 may engage the beam 101 or link 103 by sliding inside the bore 604 , thus giving making the hollow center advantageous for minimizing the use of material or to simplify manufacture . at least one hole 603 , which may be disposed perpendicular to the coupler 602 center axis , may be used to engage a locking feature on the beam 101 or link 103 such as a pin , screw , tang , nub , and so forth . in still another embodiment , a bendable tang with a hemispherical nub , also referred to as a locking tang , similar to the embodiment of such feature shown in fig7 , may be placed on one or more couplers 602 of the connector 102 to releasably secure the connector 102 to the beam 101 or link 103 . fig7 is a perspective view , right side view , front view , and bottom view of an embodiment constructible water toy connector adapter 700 . the adapter 700 may have a hollow tubular cylinder 701 bisected by a larger diameter cylinder travel limiter 702 , or circumferential flange . the circumferential flange 702 may limit the connector 102 or beam 101 engagement length . at least one locking tang 703 may be formed into the circumference of the cylinder 701 . the locking tang 703 may be cantilevered with an end joined to the cylinder 701 at a vertex 706 in order to permit radial deflection . inward deflection may allow the nub 704 to internally pass through the end of a beam 101 or connector 102 , and then snap into one or more holes 303 , 405 , 603 . when pressing or otherwise deflecting the locking tang 703 and nub 704 inward , deformation of the tang 703 may begin at the vertex 706 . the tang 703 may be created by forming a gap 705 , 707 into the tubular cylinder around the perimeter of the tang 703 . the gap 705 , 707 width may be more or less than illustrated to permit free movement of the tang 703 and nub 704 . the gap 705 near the nub 704 and the gap 707 may be different dimensions , particularly because bending of the tang 703 may cause the nub 704 to interfere with the tubular cylinder 701 . in an embodiment , the nub 704 may not be hemispherical and instead may be shaped as a triangular ramp ( not shown ) to permit disengagement of the adapter 700 from a beam 101 or connector 102 through a twisting action . in another embodiment , a bendable tang with a hemispherical nub , similar to the embodiment of such feature shown in fig7 , may be placed on one or more couplers 602 of the connector 102 to releasably secure the connector 102 to the beam 101 or link 103 . fig8 is a top view of an embodiment constructible water toy connector , a cross - section of a connector , a connector adapter , and cross - section of a connector adapter . the connector adapter 800 is shown being inserted into the connector 801 . the cylindrical outer diameter of the adapter 800 may engage the cylindrical inner diameter of the connector 801 . nubs 804 on the adapter 800 may be depressed radially inward to engage at least one hole 802 located near the end of the connector 801 . elastic yielding of the material may allow at least one cantilevered tang 805 to bend at the vertex 807 , thus allowing the nub 804 to radially deflect . upon insertion of the adapter 800 into the connector 801 , axial engagement of the adapter 800 may be limited by internal collars 803 , illustrated in section a - a , or by an external collar 808 . in an embodiment , the nubs 804 may be hemispherical to allow a user to twist the connector adapter 800 for disengagement . the twisting action , which may be applied about the center longitudinal axis of the adapter 800 , may deflect the tang 805 and cause axial depression of the nub 804 . the direction of twist , as viewed in section b - b , may be in the clockwise direction . though , if the tang 805 were reversed to the opposite side of the cylinder , then the direction of twist may be counterclockwise . a perimeter cutout 806 surrounding the nub 804 and tang 805 may be larger than illustrated to permit unimpeded radial deflection . for example , if a plastic material were chosen and if the outer diameter of the adapter 800 is 0 . 950 inches , the inner diameter is 0 . 800 inches , the nub 804 height is 0 . 200 inches , then the cutout 806 may be 0 . 125 inches . this particular combination of dimensions is provided merely as an example . many dimensional combinations of features may be employed to suit various aspects of the structural design such as rigidity , ease of assembly , ease of disassembly , ruggedness , overall weight , buoyancy , and so forth . fig9 is a top view of various embodiments of water toy connectors 900 , which are similar to 102 . it is , of course , not possible to show all possible embodiments of the connectors 900 and , thus , are not limited to the various permutations . for example , connectors 900 may have 1 through n possible connections . thus , the embodiments of connectors 901 through 909 are intended to show some possible variations . the connectors 900 shown are able to engage a beam 101 and / or a connector link 103 . a connector 900 with a single connection ( not shown ) may be placed on a beam 101 end as a stylistic feature , a protective feature , or the like . the connectors 900 may be at least partially surrounded with a soft covering , such as foam , to match the outer member of the beam 101 . for example , a connector ( not shown ) with a single connection may have a foam sphere disposed about an end opposite the connection . this type of connector may be characterized as a beam end cap , or capping means , because a beam 101 , connectors 900 , or connector links 103 are disallowed after a single - ended connector ( not shown ) is inserted into a beam 101 . furthermore , the connectors 900 may have holes disposed near the ends of the couplers to releasably engage a beam 101 and / or a connector link 103 . in an embodiment , the connectors 900 may have connector tangs ( shown as 703 , 805 ), instead of holes 802 , for directly engaging the holes 303 , 405 in the ends of the beams 101 , 400 . the outer diameter of the connectors 900 may be adapted to fit the inside diameter of the ends of the beams 101 , 400 . fig1 is partial exploded perspective view of another embodiment constructible water toy . an embodiment beam 1001 , which is similar to beam 101 , is illustrated as having a solid , inner cylindrical supporting rod 1002 , similar to an endoskeleton , with an outer tubular member 1003 . the rod 1002 may engage a connector 1004 through a friction fit , threaded joint , or the like . the connector 1004 , which is similar to connectors 900 , may have an internal support 1005 to enhance stability upon assembly into a water toy structure . as in other embodiment described herein , the connector 1004 may have a soft outer covering 1006 for aesthetic appeal , safety , and so forth . fig1 is a perspective view , end view , and cross - section of yet another embodiment constructible water toy beam 1100 , which again , is similar to 101 . as previously mentioned , at least one nub 1103 may be placed on an end of an endoskeleton support 1102 to engage a connector 102 , as illustrated in fig6 . with the nub 1103 placed on the end or ends of the beam 1100 , then connectors 900 may be used without the connector adapter 103 , 700 , 800 because the nub 1103 may engage one or more holes in the ends of the beam 1100 . fig1 is a top view of an alternate embodiment constructible water toy connector 1201 , a connector adapter 1202 , and end views of each . these components 1201 , 1202 illustrate a different coupling scheme than connector adapter 800 and connector 801 . in an embodiment , the adapter 1202 may have at least one l - shaped hook 1205 to removably engage a corresponding bifurcated collar 1203 within an end of the connector 1201 . the l - shaped hook 1205 may slide through an opening 1204 between a bifurcated collar 1203 and then , upon twisting the adapter 1202 , may engage the collar 1203 to prevent accidentally disengaging the adapter 1202 from the connector 1201 . in another embodiment , a plurality of l - shaped hooks 1205 may be disposed onto an end of an adapter 1202 . a plurality of openings 1204 may be placed within the collar 1203 to accept the plurality of hooks 1205 . a similar hook and collar configuration may be employed at the connection between an adapter 1202 and a beam ( not shown ). fig1 is a flow chart for constructing a water toy kit of parts . in an embodiment , the process 1300 may begin with placing parts of a kit in mutual proximity ( step 1301 ) to each other . a beam 101 may then be formed ( step 1302 ) by inserting an endoskeleton support 302 into a tubular beam 301 ( step 1303 ). then , a connector ( or connector adapter ) tang 805 may be deflected and a connector adapter 700 , 800 inserted into an end of the endoskeleton support 302 ( step 1304 ). the tang 805 may then be aligned with a hole 303 on the support 302 end by twisting , pulling , or and / pushing the connector adapter 700 , 800 ( step 1305 ). alternatively , a connector 900 or another beam 101 may be inserted onto the opposite end of the connector adapter 700 , 800 . the user makes a decision at this point to determine whether or not the erected structure is complete ( step 1306 ). if not complete , then steps 1302 through 1305 may be repeated . if the erected structure 100 is complete , then the process is complete ( step 1307 ). fig1 is a perspective view of another embodiment constructible water toy . a plurality of beams 101 may be joined together in parallel via connectors 901 , connector adapters 103 , and connectors 102 . in the embodiment illustrated , the beams 101 may act as a base for a floating structure such as a raft . what has been described above includes examples of one or more embodiments . it is , of course , not possible to describe every conceivable combination of components or methodologies for purposes of describing the aforementioned embodiments , but one of ordinary skill in the art may recognize that many further combinations and permutations of various embodiments are possible . accordingly , the described embodiments are intended to embrace all such alterations , modifications and variations that fall within the spirit and scope of the appended claims . furthermore , to the extent that the term “ includes ” is used in either the detailed description or the claims , such term is intended to be inclusive in a manner similar to the term “ comprising ” as “ comprising ” is interpreted when employed as a transitional word in a claim .
