Description

BACKGROUND OF THE INVENTION

[0003] 1. Field of the Invention

[0004] This invention relates generally to construction and model building toys. Specifically, the invention is a system of construction elements that are coupled together to form various shapes and models. The construction elements are capable of being interconnected and configured to form interesting, educational, and entertaining designs, models, and construction projects. The nature of the construction elements also enables movement of some construction elements relative to other construction elements when coupled together.

[0005] 2. Description of Related Art

[0006] The state of the prior art is replete with building blocks and other similar types of toys that enable construction elements to be coupled together to build models, shapes, patterns or designs in three dimensions. While these construction elements are referred to as toys, it should not be assumed that they are simplistic devices. The construction elements are capable of building complex shapes and models. Furthermore, they often include the ability to incorporate actuable elements such that they can be powered by mechanical or electrical devices, or even by manual manipulation. The result is that the construction elements are often minor engineering feats in and of themselves.

[0007] Given this introduction to so-called toy construction elements, it should not be surprising to realize that construction elements are capable of rather amazing and even ingenious ways of interlocking to thereby form rather complex models, shapes, patterns and designs.

[0008] However, given the fact that there are many different types of construction elements, and that there are many different types of connection schemes that can be used to connect them, it should also not be surprising that new and advantageous construction elements and ways of connecting them together are still possible.

[0009] Accordingly, it would be advantageous to provide a plurality of building elements that include new and advantageous means of building construction projects, models, shapes, patterns or designs, wherein only a small number of construction elements are capable of being combined in a variety of ways to enable an imaginative user to build both simple and complex projects. Finally, it would be advantageous to provide a plurality of construction elements that can be actuated so as to pivot, rotate, and otherwise move relative to each other by application of mechanical force to thereby animate the construction projects, models, shapes, patterns or designs.

DETAILED DESCRIPTION OF THE INVENTION

[0043] Reference will now be made to the drawings in which the various elements of the present invention will be given numerical designations and in which the invention will be discussed so as to enable one skilled in the art to make and use the invention. It is to be understood that the following description is only exemplary of the principles of the present invention, and should not be viewed as narrowing the claims which follow.

[0044] The presently preferred embodiment of the invention has again evolved substantially since its inception. Therefore, as the invention is explained, it is important to keep in mind that the various construction projects, models, shapes, patterns or designs that can be created using the construction elements of the invention are numerous. Accordingly, the examples given hereinafter are only able to give a very brief introduction to many design possibilities. The purpose of the inventor was to free the user to create models, shapes, patterns or designs that are limited by the user=s imagination, and not by the construction elements themselves.

[0045] The construction elements are generally manufactured from molded plastic as is commonly found in toys for children. The plastic is relatively rigid, but will bend or give slightly in order for construction elements to engage each other via friction or a snap connection. In other words, the construction elements will generally snap together, but may be required to slightly bend in order to insert or attach one construction element to another. Furthermore, it is an important aspect of the present invention that the construction elements are now primarily formed by snapping together two sides or halves to form a non-construction element that is hemispherical in nature. Thus, one side of the construction element is generally planar, and the opposite side is generally hemispherical.

[0046] In addition, other materials can be used for the construction elements. For example, wood and metal are also suitable materials. Each material has properties which can lend themselves to particular applications. Accordingly, the materials that can be used are generally all those which can for the desired construction elements, as is known to those skilled in the art.

[0047] With this brief introduction, the elements of the presently preferred embodiment will now be described. The main construction element of the present invention is a strut member. The strut members of the embodiments of the present invention are divided into three distinct types, as will be shown. Furthermore, all strut members are formed as having either a male connector or a complementary female connector so that the different halves can be joined by male and female connectors that snap together.

[0048] FIG. 1A shows two construction elements 10 and 12. The first construction element 10 is shown having a hemispherical segment 14, and a planar segment 16. The planar segment 16 has a C-claw disposed on a first end. The hemispherical segment 14 is shown from a perspective that enables viewing of the hemispherical side of the first construction element 10.

[0049] Important features to note are the various slots 18 on the first construction element 10 that enable other construction elements to be coupled to it in a rigid manner, or in a manner that enables sliding engagement. The hemispherical segment 14 also includes two hemispheres 20 that are shown being coupled via a two joining segments 22.

[0050] It is noted that while there are two joining segments because of a slot disposed between them, a single joining segment could be used.

[0051] Also in FIG. 1A is the complementary half or second construction element 12. The second construction element 12 is comprised of a hemispherical segment 24, and a planar segment 26. The hemispherical segment 24 includes two hemispheres 28 that are coupled by two joining segments 30. It is noted that slots can also be disposed as indented slots in the two hemispheres 28, wherein the indented slots can be parallel to a long axis of the construction element 10, or perpendicular to the long axis.

[0052] The first and second construction elements 10, 12 can be coupled together in a first manner by snapping together the two hemispherical segments 14, 24. Specifically, the hemispheres 28 of the second construction element 12 include a cavity therein for forming female connectors 32. The first construction element 10 includes complementary connecting features that form male connectors to be shown in FIGS. 1C and 1D.

[0053] FIG. 1B is provided as a close-up of the hemisphere 28 that is disposed on an end of the second construction element 12.

[0054] FIG. 1C shows the two construction elements 10 and 12 from FIG. 1A. The first construction element 10 is now seen from its opposite side so that complementary connecting features that form male connectors 40 are now visible. The male connectors 40 are designed to make a snap fit with the female connectors 32. The male connectors are essentially a raised and circular lip that is designed to fit into a groove within a circular aperture of the female connectors 32. The resulting construction element that is formed by snapping the first and second construction elements 10, 12 together is a strut having a C-claw at each end, and a cylindrical segment inbetween, as will be shown in other figures.

[0055] FIG. 1D is provided as a close-up of the hemisphere 20 that is disposed on an end of the first construction element 10.

[0056] Another important feature to recognize is that the planar segments 14, 26 are offset from a plane made by the two joining segments 22, 30. The planar segments 14, 26 can be considered to be raised above the plane made by the joining segments 22, 30. Because of this offset, when any two construction elements 10, 12 are coupled together, the C-claws are thus centered along a cylinder formed by the hemispherical segments 14 and 24.

[0057] FIG. 2A is a perspective view of the first construction element 10 from FIG. 1A. It is provided as a contrast to a third construction element.

[0058] FIG. 2B is a perspective view of the third construction element 50. The third construction element is comprised of a single hemispherical segment 56 having hemispheres 52 at each end thereof, and a connecting member 54 disposed therebetween. The male connectors 58 are designed to make a snap fit connection, for example, with corresponding female connectors 68 shown in FIG. 2D.

[0059] FIG. 2C is a perspective view of the first construction element 12 from FIG. 1A. It is provided as a contrast to a fourth construction element 60.

[0060] FIG. 2D is a perspective view of the third construction element 60. The third construction element is comprised of a single hemispherical segment 66 having hemispheres 62 at each end thereof, and a connecting member 64 disposed therebetween. The female connectors 68 are designed to make a snap fit connection, for example, with corresponding male connectors 58 shown in FIG. 2D.

[0061] While it has been suggested that the third and fourth construction elements can be coupled together, it should also be apparent that the first construction element 10 can be coupled to the fourth construction element 60, and the second construction element 12 can be coupled to the third construction element 50.

[0062] Furthermore, it should be stated that it is not required that the two male connectors 40 of the first construction element 10 be coupled to the two female connectors 68 of the fourth construction element 60. For example, only a single hemisphere 20 of the first construction element 10 could be coupled to a single hemisphere 62 of the fourth construction element 60. In that way, the fourth construction element 60 could be coupled at its unattached hemisphere 60 to another complementary construction element.

[0063] FIG. 3A is provided as a perspective view of three construction elements. The second construction element 12 is shown above and perpendicular relative to a planar construction element 70 having various apertures disposed therethrough. One aperture id designated as item 72. The third construction element 50 is shown disposed below the planar construction element 70.

[0064] FIG. 3B is a perspective view illustrating one possible configuration for coupling the three construction elements 12, 50, 70 together. Note that the second and third construction elements 12, 50 are snapped together through the aperture 72.

[0065] FIG. 4 is a perspective view of the same construction elements 12, 50, 70, but the second and third construction elements 12, 50 are now shifted so as not to be connected through aperture 72, but at a midpoint along the planar construction element 70. Thus, the male 58 and female 32 connectors no longer pass through the planar construction element 70, but instead fit in the rounded formations 74 shown in FIG. 3A. A slot 84 is identified in the coupled construction elements 12, 50 for FIG. 5.

[0066] FIG. 5 is provided as a perspective view of the coupled construction elements of FIG. 4, but now with additional construction element 80 that is coupled by a C-claw 82 to the slot 84.

[0067] FIG. 6A is provided is as a perspective view of six construction elements coupled together in a manner that was suggested previously. For example, the figure can show three first construction elements 10 coupled to three fourth construction elements 60. Likewise, the figure can show three second construction elements 12 coupled to three third construction elements 50. Any single construction element is always coupled to two other complementary construction elements.

[0068] FIG. 6B is a top view of the construction elements shown in FIG. 6A.

[0069] FIG. 7A is a top view of four construction elements. There are two third construction elements 50, and two fourth construction elements 60.

[0070] FIG. 7B is a top view of the four construction elements of FIG. 7A, wherein the constructions have been pushed so as to rotate at connection points in the corners of the shape. Thus, the connection points are sufficiently loose so as to be in sliding engagement, allowing rotation while still being snapped together.

[0071] FIG. 8 is a top view of the first construction element 10 coupled at only one male connector 40 to a complementary female connector 68 in the fourth construction element 60. It should be understood that the construction elements 10, 60 are able to rotate in the same plane with respect to each other, at least until protruding male and female connectors 40, 68 strike an edge of the construction elements.

[0072] FIG. 9 is a top view of the first construction element 10 coupled at a single male connector 40 to a complementary female connector 68 in the fourth construction element 60. What has changed between FIGS. 8 and 9 is that the fourth construction element 60 is now coupled to a different male connector 40 of the first construction element 10. It should be noted that the fourth construction element 60 is now almost able to make a complete rotation with respect to the first construction element 10 when coupled to a male connector 40 on the end of the first construction element.

[0073] It should also be observed that there is a gap between any two coupled construction elements between the hemispheres. For example, see the gap identified as 90 in FIG. 3B. These gaps enable planar construction members to be disposed between or coupled to the construction elements 10, 12, 50, 60. These gaps also enable connecting ends such as the C-claws of the first and second construction elements 10, 12 to be coupled to other construction elements.

[0074] It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention. The appended claims are intended to cover such modifications and arrangements.
