- This invention relates to construction elements particularly suitable for childrens entertainment, but which can also be used for structure research, models, and useful constructions such as lattice-work for creeping plants, safety rafts, or the like.
- the principle of the element of the invention is quite simple. It can be manufactured from a semi-rigid material, there being provided a cylindrical body with a halfopen grip at each end. The outer diameter of the body is equal to the inner diameter of the grips so that each ele ment can clutch the body of any other element. Both grips are open sidewards preferably on the same side in order, firstly, to enable the easy clutching of an element on a previously made construction (a median of a rectangle for instance) and, secondly, to prevent any disconnection, by a lengthwise traction, of clutched elements.
- the body of the element can be provided with shoulders or ribs defining a number of grooves in which new elements can be clutched in any position without any possibility of sidewards movements.
- the size of the elements may vary from a few inches to several feet, depending upon the chosen material.
- the very simple design of the element is specially convenient for the production of plastic or rubber-inflated elements, the latter being provided with a small air valve.
- the welding of air-proof plastics or rubber sheets is quite easy to effect, particularly when using the heating properties of high electric or acoustic frequencies, and the weld- 3,550,311 Patented Dec. 29, 1970 ing profile, corresponding with the development of the cylindrical body and of the round grips can be realized in a single plane.
- the stiffness of the grips will depend on the inner air pressure. It can be easily sufiicient to insure a good grasp of the different elements on each other and to enable the assembly of all kinds of out-doors constructions, mattresses, safety or rest rafts and so forth.
- the element is preferably produced in a small size, and manufactured by the injection molding of a thermoplastic material.
- the range of the available materials is wide enough to offer every quality of stiffness and grasping strength which may be useful.
- this last technique enables some interesting improvements of the outlines of the element, thus offering very advantageous possibilities of construction.
- FIG. 1 This embodiment comprises an elongated body or cylindrical rod 10 of a length a and on which are mounted a plurality of concentric annular rings 12 integral with said rod. These rings divide the rod into a plurality of seg ments 14, the total of which is preferably odd in number so that one of the segments constitutes the exact center of the rod.
- clutching elements or grippers 16 and 18 At the ends of the rod 10 are clutching elements or grippers 16 and 18 having centrally located openings 20 and 22, the diameters of which approximate that of the rod 10.
- Slots 24 and 26 are provided by means of which openings 20 and 22 open outwardly to the same side of the rod 10.
- the slots 24 and 26 are of a dimension which is less than the diameter of the rod 10 so that another similar constructional element can be engaged by forcing the same through the slots 24 and 26 to a position of accommodation within the openings 20 and 22.
- the outer diameter b of each of the clutching elements is equal to the length l of the segments 14.
- the distance d from the center of the openings to the center of the segment next adjacent each of the clutching elements is preferably equal to the length l of the segments.
- the above construction may preferably be fabricated of a monolithic structure of plastic or rubber or the like but can alternatively be fabricated, for example, such that the rod is made of metal and clutching elements 16 and 18 are made of plastic or rubber and affixed to said rod.
- Suitable plastics include, but are not limited to, polyethylene, polystyrene, polyurethane and so forth.
- FIGS. 2a and 2b a structure is shown formed of inflatable rubber.
- a center rod 28 is provided at the ends of which are formed clutching elements 30 and 32.
- a one-way valve 34 capable of admitting a pneumatic medium into the structure to enable the latter to assume its useful form.
- Known techniques for welding plastics or rubber sheets in hermetically sealed manner involve the use, as has been indicated above, of conventional high-frequency welding techniques.
- the rigidity of the grips or clutching elements will depend upon the pressure of the pneumatic medium and there will be an inherent resiliency such as will permit the insertion of the elements to be gripped through slots 36 and 38 into openings 40 and 42.
- Annular ribs may, of course, be provided on center rod 28 in the manner as has been indicated above with respect to FIG. 1.
- FIG. 3 A more sophisticated version of a construction element provided in accordance with the invention appears in FIG. 3.
- This construction is generally the same as has been dis cussed above and employs the circular rings or ribs defining an uneven number of grooves or segments as has already been discussed.
- the clutching elements have been modified in order to enable a linear assembly of construction elements without interruption of the regular succession of segments or grooves. In fact, the spacing of the succession of grooves is maintained from one element to the next in the succession so that the advantageous possibilities of construction present with the single element are also present in the assembly.
- a center cylindrical rod or elongated body 48 having longitudinal axis 49.
- Body 48 has rings 50 thereon with coupling means 52 and 54 disposed on the ends thereof and extending in rectilinear alignment therewith. Between said rings, the body 48 is of at least substantially uniform cross-section.
- the coupling means includes clutching elements which consist of C-shaped portions56 and 58 connected by saw-tooth elements 60 and 62 to cylindrical elements 64 and 66.
- the common length of the sections 68 is equal to the distance between the center of openings 70 and 72 to the centers of the next adjacent sections 68. These dimensions in turn are equal to the distances between the centers of openings 70 and 72 to the centers of cylindrical sections 64 and 66.

- the diameters of cylindrical elements 64 and 66 are equal to the diameters of openings 70 and 72 which have laterally opening slots S of smaller dimensions.
- sawtooth element 60 defines with cylindrical element 64 a saw-tooth opening 74 of a shape corresponding to that of saw-tooth element 60.
- a similar relationship is provided as between saw-tooth element 62 and cylindrical element 66 and the saw-tooth opening 76 defined therebetween.
- the axes of the cylindrical elements 64 and 66 are parallel with the axes of openings 70 and 72.
- the C-shaped portions or clutching elements 56 and 58 are so dimensioned with respect to saw-tooth elements 60 and 62 as to permit other construction elements engaged in openings 70 and 72 to pivot between a 90 and 120 relationship with respect to rod 48.

Int. Cl. A63h 33/08 US. Cl. 46-28 8 Claims ABSTRACT OF THE DISCLOSURE Interengageable construction elements, particularly suited for children but also useful in regular constructions, each such element being made in the form of an elongated body having resiliently engageable clutching elements at the ends thereof. This body is provided with spaced annular ribs and the clutching elements thereon form extensions of the body terminating in a cylindrical extremity. Also, each clutching element has a circular opening to receive the extremity of another clutching element.
DRAWING DETAILED DESCRIPTION This invention relates to construction elements particularly suitable for childrens entertainment, but which can also be used for structure research, models, and useful constructions such as lattice-work for creeping plants, safety rafts, or the like.
The principle of the element of the invention is quite simple. It can be manufactured from a semi-rigid material, there being provided a cylindrical body with a halfopen grip at each end. The outer diameter of the body is equal to the inner diameter of the grips so that each ele ment can clutch the body of any other element. Both grips are open sidewards preferably on the same side in order, firstly, to enable the easy clutching of an element on a previously made construction (a median of a rectangle for instance) and, secondly, to prevent any disconnection, by a lengthwise traction, of clutched elements. The body of the element can be provided with shoulders or ribs defining a number of grooves in which new elements can be clutched in any position without any possibility of sidewards movements.
This simple design enables a wide variety of assemblies. In two dimensions all kinds of rigid or articulated latticework are possible; in three dimensions, a complete range of squareor rectangularor polygonal-based assemblies, articulated or rigid are possible as well. Rigidity is obtained by clutching diagonal elements, or by opposing under a 90 angle the direction of the grips of some elements of the construction.
The size of the elements may vary from a few inches to several feet, depending upon the chosen material. The very simple design of the element is specially convenient for the production of plastic or rubber-inflated elements, the latter being provided with a small air valve. Indeed, the welding of air-proof plastics or rubber sheets is quite easy to effect, particularly when using the heating properties of high electric or acoustic frequencies, and the weld- 3,550,311 Patented Dec. 29, 1970 ing profile, corresponding with the development of the cylindrical body and of the round grips can be realized in a single plane. The stiffness of the grips will depend on the inner air pressure. It can be easily sufiicient to insure a good grasp of the different elements on each other and to enable the assembly of all kinds of out-doors constructions, mattresses, safety or rest rafts and so forth.
Large elements can be manufactured as well out of semi-rigid or rigid expanded materials such as rubber, polyurethane or polystyrene foam, by the cutting of boards, or by the convenient molding of foam cells.
The element is preferably produced in a small size, and manufactured by the injection molding of a thermoplastic material. The range of the available materials is wide enough to offer every quality of stiffness and grasping strength which may be useful. Moreover, this last technique enables some interesting improvements of the outlines of the element, thus offering very advantageous possibilities of construction.
With more particular reference to the drawing, one embodiment of the invention is illustrated in FIG. 1. This embodiment comprises an elongated body or cylindrical rod 10 of a length a and on which are mounted a plurality of concentric annular rings 12 integral with said rod. These rings divide the rod into a plurality of seg ments 14, the total of which is preferably odd in number so that one of the segments constitutes the exact center of the rod. At the ends of the rod 10 are clutching elements or grippers 16 and 18 having centrally located openings 20 and 22, the diameters of which approximate that of the rod 10. Slots 24 and 26 are provided by means of which openings 20 and 22 open outwardly to the same side of the rod 10. The slots 24 and 26 are of a dimension which is less than the diameter of the rod 10 so that another similar constructional element can be engaged by forcing the same through the slots 24 and 26 to a position of accommodation within the openings 20 and 22. The outer diameter b of each of the clutching elements is equal to the length l of the segments 14. The distance d from the center of the openings to the center of the segment next adjacent each of the clutching elements is preferably equal to the length l of the segments.
The above construction may preferably be fabricated of a monolithic structure of plastic or rubber or the like but can alternatively be fabricated, for example, such that the rod is made of metal and clutching elements 16 and 18 are made of plastic or rubber and affixed to said rod. Suitable plastics include, but are not limited to, polyethylene, polystyrene, polyurethane and so forth.
In the embodiment of the invention illustrated in FIGS. 2a and 2b, a structure is shown formed of inflatable rubber. In this embodiment of the invention a center rod 28 is provided at the ends of which are formed clutching elements 30 and 32. Conveniently disposed on this construction is a one-way valve 34 capable of admitting a pneumatic medium into the structure to enable the latter to assume its useful form. Known techniques for welding plastics or rubber sheets in hermetically sealed manner involve the use, as has been indicated above, of conventional high-frequency welding techniques. The rigidity of the grips or clutching elements will depend upon the pressure of the pneumatic medium and there will be an inherent resiliency such as will permit the insertion of the elements to be gripped through slots 36 and 38 into openings 40 and 42. Annular ribs may, of course, be provided on center rod 28 in the manner as has been indicated above with respect to FIG. 1.
A more sophisticated version of a construction element provided in accordance with the invention appears in FIG. 3. This construction is generally the same as has been dis cussed above and employs the circular rings or ribs defining an uneven number of grooves or segments as has already been discussed. In addition, the clutching elements have been modified in order to enable a linear assembly of construction elements without interruption of the regular succession of segments or grooves. In fact, the spacing of the succession of grooves is maintained from one element to the next in the succession so that the advantageous possibilities of construction present with the single element are also present in the assembly.
More particularly, in this embodiment of the invention there is included a center cylindrical rod or elongated body 48 having longitudinal axis 49. Body 48 has rings 50 thereon with coupling means 52 and 54 disposed on the ends thereof and extending in rectilinear alignment therewith. Between said rings, the body 48 is of at least substantially uniform cross-section. The coupling means includes clutching elements which consist of C-shaped portions56 and 58 connected by saw- tooth elements 60 and 62 to cylindrical elements 64 and 66. As indicated by dimensions x, the common length of the sections 68 is equal to the distance between the center of openings 70 and 72 to the centers of the next adjacent sections 68. These dimensions in turn are equal to the distances between the centers of openings 70 and 72 to the centers of cylindrical sections 64 and 66. The purpose of maintaining these dimensions will become apparent when viewed with respect to the various possible assemblies as will be discussed hereinafter.
In addition to the above dimensions, it will be noted that the diameters of cylindrical elements 64 and 66 are equal to the diameters of openings 70 and 72 which have laterally opening slots S of smaller dimensions. It will also be noted that sawtooth element 60 defines with cylindrical element 64 a saw-tooth opening 74 of a shape corresponding to that of saw-tooth element 60. A similar relationship is provided as between saw-tooth element 62 and cylindrical element 66 and the saw-tooth opening 76 defined therebetween.
The axes of the cylindrical elements 64 and 66 are parallel with the axes of openings 70 and 72. As will be shown, the C-shaped portions or clutching elements 56 and 58 are so dimensioned with respect to saw- tooth elements 60 and 62 as to permit other construction elements engaged in openings 70 and 72 to pivot between a 90 and 120 relationship with respect to rod 48. This will also be discussed hereinafter. 135 to 144 relationships are also permissible as will be shown.
FIGS. 4a-g illustrate various assemblies permissible with the construction element of FIG. 3. In FIG. 4a is shown a three-spoke arrangement consisting of construction elements 80, 82 and 84 with a hub 86 being formed of three interengaged clutching elements as have been described above. FIG. 4b shows another arrangement of three- construction elements 88, 90 and 92 wherein elements 90 and 92 are pivotable in respect of hub 94. FIG. 40 illustrates a rectilinear alignment of construction elements 96, 98 and 100 with clutching element assemblies 102 and 104 connecting said construction elements together. Assemblies 102 and 104 illustrate how the clutching elements are placed into mating engagement especially in respect of the mating saw-tooth openings and teeth. Also of particular interest in FIG. 40 is the perpendicular arrangement of a fourth construction element 106 whose clutching 108 is of such a width as to fit exactly onto one of the segments of construction element 96.
FIG. 4d illustrates the possibility of assuming angle m between construction elements 110 and 112, angle In being equal to 135, the same relationship being developed between construction elements 114, 116 and 118. In this arrangement it will be noted that the extremities 120 of the clutching elements come into abutting or nearly abutting relationship. The angle n in FIG. 4e illustrates the development of the 120 relationship between construction elements 122, 124, 126 and 128.
FIG. 4 illustrates a lattice arrangement, two forms thereof being illustrated at 130 and 132, dependent upon the location of the transverse elements 134 and 136. FIG.
4 4g illustrates a further lattice network 138 partitioned by a center member 140.
FIG. 4h illustrates a further possible arrangement consisting of an interengaged quadrilateral hub 142.
The constructions noted above can be supplemented by various accessories such as wheels, pulleys, panels and so forth to permit a wider latitude of usage. There is illustrated in FIG. 5, for example, a wheel 144 consisting of a rim 146, a hub 148 and spokes 150. The hub is provided with a central opening 152 in which the central rod 154 appears, the latter having been inserted via slot 156, the dimensions of which permit the rod to be inserted with force and locked in said opening. The resiliency of the materials employed will permit the insertion of the rod. Preferably, the diameter of spokes is equal to the diameter of rim 146 which is equal to the diameter of the opening 152.
Quite generally there has been discussed above an elongated body having resiliently openable clutching elements mounted on the spaced ends thereof. The clutching elements are preferably provided with openings which open to the same side of the associated body which preferably includes evenly spaced annular ribs longitudinally distributed along the body. The openings are at least substantially of the same size as the body so as to be able to accommodate the insertion of construction elements of like configuration.
Such construction elements as has been noted may be of a one-piece construction, an inflatable construction or an assembly of different elements. Accessories of the various types can be provided.
The clutching elements can be developed to permit a rectilinear alignment of a plurality of construction elements.
There will now be obvious to those skilled in the art many modifications and variations of the construction set forth hereinabove.
