## Background
FIELD OF THE INVENTION
The present invention relates generally to construction sets, and more particularly to construction toys with multiple shaped components removably connectable with male and female connectors.
BACKGROUND OF THE INVENTION
Construction toys have been developed over the years for play, education, and industry modeling. Among the various examples are erector and leggo construction toys.
In the case of erector sets, bolts and screws are used to assemble components. Erector components are generally planar and require construction to build three dimensional components.
In the case of leggos, components are connected by pressing together male and female portions. Components are three dimensional, however they are limited in the angular orientation of connecting components. Also, the male and female connector portions generally are smooth and held together with friction, resulting in reduced stability and ultimately abrasive wear on components.
Various others have attempted to overcome some of the limitations of such designs with various levels of success. There continues to be a need for multi-functional construction toys with multi-faceted and multi-angular connectable components. There also continues to be a need for reusable connector portions that lock into position and provide greater stability while being simple to use.
SUMMARY OF THE INVENTION
In accordance with the present invention, a multi-functional construction toy includes inter-connectable reusable snap-lock components that are multi-faceted and multi-angular enabling a user to construct assemblies of various shapes.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, an embodiment of male snap-lock connector 10 and female bidirectional snap-lock connector 12 is shown in accordance with the present invention. Connectors 10, 12 are implemented as a part or portion of construction components. Connectors 10, 12 enable detachable snap-lock connection of various components some of which are described more fully hereinafter as components of a construction toy in accordance with the present invention.
Male snap-lock connector 10 is formed with a rigid plastic and shaped with head 14, neck 16, and shoulders 18. In one embodiment head 14, neck 16, and shoulder 18 are circular-shaped around a central axis extending longitudinally. In the embodiment shown in FIG. 1, head 14 extends from neck 16 and has a widened central diameter region 20 and narrowed tip 22. In another embodiment (as seen in FIG. 3), head 14 has a mushroom shaped tip 22. In yet another embodiment (as may be deduced from FIG. 2), head 14 has a spherical shape. In the embodiment shown in FIG. 1, neck 16 has a conical shape with narrow region 24 joining with the base of head 14 and a wider region 26 joining with shoulder 18. In another embodiment as shown in FIG. 2, neck 16 narrows where it joins with head 14 and has a cylindrical shape. In the embodiment shown in FIG. 1, shoulder 18 is cylindrically shaped with a smooth circular circumference. In another embodiment (as may be deduced from FIGS. 4A and 4B) shoulder 18 is octagonally shaped around its perimeter.
Female bidirectional snap-lock connector 12 is formed with a rigid plastic wall that is generally cylindrically shaped with a hollow interior and extends upward from base 27. The interior of wall 28 is sized and proportioned to receive male snap-lock connector 10 when male connector 10 is inserted in the direction shown by the arrow and seated as shown with the dashed lined image of male connector 10. The interior of wall 28 includes head shaped region 30, neck shaped region 32, and shoulder shaped region 34. In one embodiment, shoulder shaped region 34 forms a octagonally shaped wall. Wall 28 includes one or more gaps (or regions of separation) extending longitudinally from upper region 36 (as shown in FIGS. 4A and 4B). In one embodiment, the gap extends near to base 27; and in another embodiment, the gap extends through base 27. The gap or gaps enable the interior of wall 28 to elastically expand (or deflect) as the head of male connector 10 is pushed through neck shaped region 32 and to substantially return to its original state once the head 14 of male connector 10 is lodged within the head shaped region 30 of female connector 12.
As the head 14 slips into the head shaped region 30, the shoulder 18 mates with the interior portion of wall 28 forming the shoulder shaped region 34. In the event that shoulder 18 has a octagonal shape, then male connector 10 is locked into a particular orientation with respect to female connector 12. The orientation of the mated connectors may be adjusted by axially twisting with a small amount of pressure to cause the faces of the octagonal shoulder 18 to shift with respect to the octagonal faces of the shoulder shaped region of wall 28. In the event that shoulder 18 is circular, then male connector 10 can spin freely around its axis within female connector 12.
It may further be appreciated that female connector 12 is bi-directional in that male connector 10 may be inserted from either the direction of base 27 or upper region 36. It may also appreciated that in the event that head region 30 is over-sized to provide for two heads 20, then two male connectors 10 may mate simultaneously with female 12. It may also be appreciated that while symmetrical octagonally shaped female shoulder cavities and corresponding male shoulder regions have been shown and described herein, other geometric shapes may be implemented including three, four, five, and n-sided shapes which may be symmetrical or asymmetrical, ‘n’ being an integer value. It may be further appreciated that while substantially sharp edges have been described herein, shapes with rounded edges are conceivable, such as, by example, a shamrock (four-sided) or cloverleaf (three-sided) shape.
As a further feature of the invention, it may be noted that the male and female components connect axially. This connection provides both axial and lateral support when the head lodges into position in the female head cavity and the neck cavity elastically contracts to surround the neck of the male.
Additionally, in the manufacturing process, plastic may be efficiently injected to produce male and female components. The components can be manufactured with simple 2-plate injection molds without the need for side core pulling. The injection molds can simultaneously produce multiple female connectors and associated components without the constraints imposed by the side-core pulling mechanisms.
Continuing to refer to FIG. 1, it may be appreciated that in the manufacturing process, a moving plate may be applied axially from the top and surrounding the volume to be filled by the female connector and the associated component, and, a base plate (ejector plate) may extend up from the base to fill the cavity of the lower shoulder, lower neck and head of the female connector. The moving plate inserts into the cavity to be formed between the upward reaching base portion of the component and the female external surface and also inserts into the shoulder and neck cavity of the female connector to be formed. The plastic may be injected into the volume including the female connector and associated component. When the injection molds opens, the moving plate is no longer pressing on the inner and outer surfaces of the component, allowing the supporting circular wings of the female cavity to deflect while the part is ejected from the plate.
Referring to FIG. 2, a second embodiment of female snap-lock connector 42 is shown fixed to and connected to base 43 in accordance with the present invention. Female connector 42 extends upward from base 43 and is tubular shaped with a spherical top portion. The interior of female connector 42 is hollow and the interior wall includes a spherically shaped head region 44, cylindrically shaped neck region 46, and sloping shoulder region 48. The interior wall of female connector 42 is shaped and proportioned to accommodate a male connector with a ball-shaped head. Gap 50 is shown separating opposing sides of the wall forming female connector 42. Gap 50 extends longitudinally towards base 43 sufficiently to enable the opposing walls of female connector 42 to elastically separate as the head of a male connector is pressed through neck region 46 and to spring back into position as the head of the male connector slips into head region 44 of female connector 42.
Referring to FIG. 3, female snap-lock connector 12 is shown with two alternative embodiment male snap-lock connectors 54, 56. Male snap-lock connectors 54, 56 have similar necks and shoulders as male connector 10. Heads 58, 60 of male connectors 54, 56 are mushroom-shaped and sized with an axial length of approximately 1⁄2 of head 14 of male connector 10 permitting both heads 58, 60 to share the cavity of head region 30 of female connector 12.
Referring to FIG. 4A, elbow component 70 is shown with four bidirectional female connectors 12 extending upward from base 27 in accordance with the present invention. (For frame of reference, the view shown in FIG. 4A is referred to as the upper view). Elbow component 70 has corner 72 joining arms 74, 76 which are fixed at a ninety degree angle with respect to each other. Elbow component 70 also includes a forty-five degree arm 78 which is spaced forty-five degrees from arms 74, 76 and on the x-y plane formed by arms 74, 76. A single female connector 12 extends upward from corner 72, arms 74, 76, and forty-five degree arm 78 such that male connectors (such as male connectors 54 shown in FIG. 3) may be mated with the upper end of female connectors 12 at a ninety-degree angle with respect to the x-y plane. Also, as may be seen by referring to FIG. 4B (for frame of reference referred to as the rearward view), male connectors (such as male connectors 56 shown in FIG. 3) may be simultaneously connected with the rearward end of female connectors 12.
Elbow component 70 includes two unidirectional female connectors 80 which respectively extend outward along arms 74, 76 in the x-y plane, such that male connectors (e.g. male connector 10, 54, or 56) may be snapped into position along the x-y plane.
Referring to FIGS. 4A, 4B, unidirectional female connector 80 includes head 86, neck 88, and shoulder 90. Female connector 80 has a gap 92 that extends longitudinally along the upward facing wall. Female connector 80 has an open surface joining with base 27. Head 86 and neck 88 of female connector 80 has inner walls that extend sufficiently (greater than 180 degrees) around the circumference of female connector 80 to permit a male connector to be pressed either longitudinally into or axially onto female connector 80 and to snap back into place once the male connector slips into the head, neck, and shoulder cavities of female connector 80. Additionally, the interior perimeter of shoulder 90 of female connector 80 is octagonally shaped to lock a male connector with a octagonally shaped exterior perimeter of its shoulder into a particular orientation with respect to the female connector. The orientation of the male connector can be changed by applying pressure axially to shift the orientation of the male shoulder with respect to the female shoulder.
Elbow component 70 includes female U-joint connector 84 extending outward from forty-five degree arm 78. The arms of female U-joint connector 84 are open sufficiently (less than one eighty degrees) to permit a shaft connector to be pressed between the open arms and oriented to snap back into place to grasp a shaft connector at a ninety degree angle with respect to the x-y plane. By mating with U-joint connector 84, a construction component with a mating male shaft connector can be attached to elbow connector 70 and rotate in the x-y plane. It may be appreciated that the U-joint connector 84 may alternatively be replaced by a male shaft connector or that the orientation of the connector with respect to the x-y plane may be disposed at a different angle (such as at a zero degree angle with respect to the x-y plane). Also, it may be appreciated that various combinations of female or male connectors may be implemented at the ends of the respective arms of elbow component 70 and that the representation shown in FIGS. 4A & 4B is simply one example.
Referring to FIG. 5A, an upper view of tee component 100 is shown comprising two arms 102, 104 joined together in a tee in accordance with the present invention and describing an x-y plane.

Arm 104 extends along the y-axis and includes one bidirectional female connector 12 extending upward from base 27 and one unidirectional female connector 80 extending from the end of arm 104 along the y-axis. Male connectors are insertable into female connectors 12 perpendicular to the x-y plane (z-axis); and, in the event that the shoulders of the male connectors are octagonally-shaped so they can mate with octagonally-shaped female shoulders 36, then the respective male connectors can be locked into a selected orientation with respect to the respective female connectors.
Tee component 100 also includes two forty-five degree arms 106 which are spaced forty-five degrees from arm 104 and on the x-y plane formed by arms 102, 104. Arms 102, 104, 106 include unidirectional female connectors 80 which respectively extend outward along each arm and in the x-y plane, such that male connectors (e.g. male connector 10, 54, or 56) may be snapped into position along the direction of the respective arm and in the x-y plane.
