Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its applications to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention can be implemented with other embodiments and can be practiced or carried out in various ways. It is also understood that the phraseology and terminology employed herein is for descriptive purpose and should not be regarded as limiting.

For purposes of this disclosure, “top”, “bottom”, “upper”, and “lower” are relative to one typical orientation of the toy building block(s), with the bottom or lower portion being a side, or adjacent to a side, adapted to be inserted into another toy building block, and the top or upper portion being a side, or adjacent to a side, adapted to receive another toy building block therein.

For the purposes of this disclosure, “substantially” is defined as “at least 95% of the term being described”, or “within a 5% margin from the term being described”.

For the purposes of this disclosure, a surface is considered to be “convex” if from an exterior of a toy building block including the surface, and when viewed from the top of the toy building block, the surface appears convex.

For the purposes of this disclosure, a surface is considered to be “concave” if from an exterior of a toy building block including the surface, and when viewed from the top of the toy building block, the surface appears concave.

For the purposes of this disclosure, the terms “light conducting” and “light guiding” are used interchangeably, and define a material or structure which receives illumination from one end and transports the light to the other end thereof, without the light significantly dissipating or being enhanced. A “light conducting” material does not generate light, but merely conducts light it receives, such as from another light source.

For the purposes of this disclosure, the terms “light generating” and “light source” define a material or structure which emits light generated within the material or structure. A light source does not need to receive light in order to emit light.

Reference is now made to FIGS. 1A and 1B, which are, respectively, a top and side perspective view illustration and a bottom and side perspective view illustration of a first light conducting toy building block 100 according to an embodiment of the teachings herein, to FIGS. 2A, 2B, and 2C, which are, respectively, top, bottom, and side planar views of the light conducting toy building block 100 of FIGS. 1A and 1B, and to FIG. 3, which is a sectional illustration of the to by building block 100 of FIGS. 1A to 2C.

As seen in FIGS. 1A to 3, light conducting toy building block 100 includes a body portion 102, which is typically formed of an opaque, colored material. Body portion 102 includes an upper surface 104, sometimes termed the nominal upper surface of toy building block 100, side surfaces 106, and a lower surface 108, sometime termed the nominal lower surface of toy building block 100.

Body portion 102 includes a plurality of bores 110, each of which has disposed therein a prong 112. At least one such prong 112, and in some embodiments all the prongs 112 disposed within toy building block 100, is/are light conducting or light guiding, and may be formed of any suitable material including glass, one or more optical fibers, transparent plastic, or any other light conducting or light guiding material.

Each prong 112 includes a first end 114, extending longitudinally outwardly from lower surface 108 of body portion 102, and terminating below the nominal lower surface, and a second end 116 disposed within corresponding bore 110 below nominal upper surface 104, as seen clearly in the sectional illustration in FIG. 3, such that an upper portion of the bore remains unfilled by the prong.

Toy building block 100 illustrated in FIGS. 1A to 3 is a square toy block, such that side surfaces 106 thereof are all substantially identical in size, and are all substantially perpendicular to upper surface 104 and to lower surface 108. In the illustrated embodiment, toy building block 100 includes four prongs 112, disposed equidistantly about the toy building block. However, the toy building block may include any suitable number of prongs. For example, the toy building block may include sixteen equidistantly disposed prongs forming a 4×4 matrix, may include two prongs disposed along a central line of the toy building block, or any other suitable number and/or arrangement of prongs.

Toy building block 200 is substantially similar to toy building block 100 of FIGS. 1A to 3, but is rectangular. As such, upper and lower surfaces 204 and 208 are connected by a first pair of side surfaces 206a along short edges thereof, and by a second pair of side surfaces 206b along long edges thereof, side surfaces 206a and 206b being substantially perpendicular to upper and lower surfaces 204 and 208. Toy building block 200 includes bores 210 and prongs 212 substantially as described hereinabove with respect to bores 110 and prongs 112 of toy building block 100. In the illustrated embodiment, toy building block 200 includes two prongs 212, disposed equidistantly along the long direction of the toy building block and centered with respect to the short direction of the toy building block. However, the toy building block may include any suitable number of prongs in any suitable arrangement.

Toy building block 200 does not generate or emit light, other than light received from another source. Toy building block 200 is devoid of any light source. Toy building block 200 is further devoid of any electronic component.

Reference is now made to FIGS. 5A and 5B, which are, respectively, a top and side perspective view illustration and a bottom and side perspective view illustration of a third light conducting toy building block 300 according to an embodiment of the teachings herein.

Toy building block 300 is substantially similar to toy building block 200 of FIGS. 4A and 4B, and includes upper and lower surfaces 304 and 308 connected by a first and second pairs of side surfaces 306a and 306b, side surfaces 306a and 306b being substantially perpendicular to upper and lower surfaces 304 and 308. Toy building block 300 includes bores 310 and prongs 312 substantially as described hereinabove, and specifically includes eight prongs 312, arranged in two rows of four prongs, the rows being disposed equidistantly with respect to the short edge of the toy building block and the prongs within each row being disposed equidistantly with respect to the long edge of the toy building block. However, the toy building block may include any suitable number of prongs in any suitable arrangement.

Toy building block 300 does not generate or emit light, other than light received from another source. Toy building block 300 is devoid of any light source. Toy building block 300 is further devoid of any electronic component.

Reference is now made to FIGS. 6A, 6B, and 6C, which are, respectively, a top and side perspective view illustration, a bottom and side perspective view illustration, and a sectional illustration of a fourth light conducting toy building block 400 according to an embodiment of the teachings herein, the sectional illustration taken along section lines VIC-VIC in FIG. 6A.

As seen in FIGS. 6A to 6C, light conducting toy building block 400 includes a body portion 402, which is typically formed of an opaque, colored material. Body portion 402 has a generally square upper surface 404, sometimes termed the nominal upper surface of toy building block 400, which includes four edges 405a, 405b, 405c, and 405d. Body portion 402 has a generally square lower surface 408, sometime termed the nominal lower surface of toy building block 400, which includes four edges 409a, 409b, 409c, and 409d. Upper surface 404 of toy building block 400 has an area significantly smaller than lower surface 408, such that the area of upper surface 404 is equal to approximately a quarter of the area of lower surface 408. Surfaces 404 and 408 are arranged such that one corner thereof is vertically aligned. As such, edges 405a and 405b of surface 404 are vertically aligned with edges 409a and 409b of surface 408. However, edges 405c and 405d of surface 404 are disposed above the area of surface 408, and are not vertically aligned with edges 409c and 409d.

A first pair of side surfaces 406a connect edges 405c and 405d of surface 404 to edges 409c and 409d of surface 408. Because the edges 405c and 405d are not vertically aligned with edges 409c and 409d, the side surfaces 406a are not perpendicular to surfaces 404 and 408, and span some of the gap between the surfaces 404 and 408. In the illustrated embodiment, the surfaces 406a are disposed at an obtuse angle relative to upper surface 404, and at an acute angle relative to lower surface 408.

A second pair of side surfaces 406b, connect edges 405a and 405b of upper surface 404 to edges 409a and 409b of lower surface 408, respectively. Because edges 405a and 405b are vertically aligned with edges 409a and 409b, side surfaces 406b are substantially perpendicular to upper and lower surfaces 404 and 408 and to each other. However, because the side surfaces 406a are angled, the connection of side surfaces 406a with side surfaces 406b is at an angled, and as such all the side surfaces 406a and 406b are generally trapezoidal, where side surfaces 406b form right angle trapezoids.

Similarly to toy building block 100 of FIGS. 1A to 3, body portion 402 includes a plurality of bores, each of which has disposed therein a prong, at least one of the prongs being light conducting or light guiding. In an area in which upper surface 404 is aligned with, and disposed above, lower surface 408, a bore 410a is throughgoing, and extends through the entirety of body portion 402. A prong 412a disposed in bore 410a includes a first end 414a disposed lower than lower surface 408 and a second end 416a disposed within the bore 410a, such that a portion 418a of the bore 410a is unfilled by the prong and accessible via upper surface 404, as seen clearly in FIG. 6C.

In areas of the housing in which side surfaces 406a are disposed vertically above lower surface 408, bores 410b extend only partially through the body portion, such that the bore terminates lower than side surface 406a, as seen clearly in FIG. 6C. A prong 412b is disposed within each bore 410b, such that a first end 414b of the prong is disposed lower than lower surface 408 and a second end 416b is disposed within the bore 410b and terminates within body portion 402, such that it is not accessible via upper surface 404 or side surface 406a, as seen clearly in FIG. 6C. As such, light conducted by prongs 412b would not be visible when viewing toy building block 400 from above, or from the side.

In the illustrated embodiment, toy building block 400 includes one prongs 412a, and three prongs 412b, such that all the prongs are arranged in two rows of two prongs each, in a similar arrangement to that described hereinabove with respect to FIGS. 1A to 3. However, the toy building block may include any suitable number of prongs in any suitable arrangement.

Toy building block 400 does not generate or emit light, other than light received from another source. Toy building block 400 is devoid of any light source. Toy building block 400 is further devoid of any electronic component.

Reference is now made to FIGS. 7A and 7B, which are, respectively, a top and side perspective view illustration and a bottom and side perspective view illustration of a fifth light conducting toy building block 500 according to an embodiment of the teachings herein.

As seen in FIGS. 7A and 7B, light conducting toy building block 500 includes a body portion 502, which is typically formed of an opaque, colored material. Body portion 502 has a generally rectangular upper surface 504, sometimes termed the nominal upper surface of toy building block 500, which includes four edges 505a, 505b, 505c, and 505d. Body portion 502 has a generally square lower surface 508, sometime termed the nominal lower surface of toy building block 500, which includes four edges 509a, 509b, 509c, and 509d. The area of upper surface 504 is significantly smaller than the area of lower surface 508, and is equal to approximately a half of the area of lower surface 508, such that edges 505b and 505d are substantially equal in length to edges 509b and 509d, but edges 505a and 505c are approximately half the length of edges 509a and 509c. Surfaces 504 and 508 are arranged such that two corners thereof are vertically aligned, and as such edges 505a, 505b, and 505c of surface 504 are vertically aligned with edges 509a, 509b, and 509c of surface 508. However, edge 505d of surface 504 are disposed above the area of surface 508, and are not vertically aligned with edge 509d.

A first generally rectangular side surface 506b connects edges 505b and 509b, which have substantially the same length and are vertically aligned. As such, rectangular side surface 506a is generally perpendicular to upper and lower surfaces 504 and 508.

A second generally rectangular side surface 506d connects edges 505d and 509d, which have substantially the same length. However, because edges 505d and 509d are not vertically aligned, side surface 506d is perpendicular to surfaces 504 and 508, and spans some of the gap between the surfaces 504 and 508. In the illustrated embodiment, the surface 506d is disposed at an obtuse angle relative to upper surface 504, and at an acute angle relative to lower surface 508.

A pair of side surfaces 506a and 506c, connect edges 505a and 505c of upper surface 504 to edges 509a and 509c of lower surface 508, respectively. Because edges 505a and 505c are vertically aligned with edges 509a and 509c, side surfaces 506a and 506c are substantially perpendicular to upper and lower surfaces 504 and 508, and to side surface 506b. However, because the side surface 506d is angled, the connection of side surfaces 506a and 506c with side surface 506d is at an angled. As such, side surfaces 506a and 506c form right angle trapezoids.

Similarly to toy building block 100 of FIGS. 1A to 3, body portion 502 includes a plurality of bores, each of which has disposed therein a prong, at least one of the prongs being light conducting or light guiding. Similarly to that described above with respect to FIGS. 6A to 6C, toy building block 500 includes throughgoing bores 510a which include prongs 512a, and bores 510b similar to bores 410b of FIGS. 6A to 6C, disposed beneath side surface 506d, which span only part of the height of the body portion 502, and include prongs 512b which are not visible when looking at the toy building block 500 from above or from the side.

In the illustrated embodiment, toy building block 500 includes two prongs 512a, and two prongs 512b, such that all the prongs are arranged in two rows of two prongs each, in a similar arrangement to that described hereinabove with respect to FIGS. 1A to 3. However, the toy building block may include any suitable number of prongs in any suitable arrangement.

Toy building block 500 does not generate or emit light, other than light received from another source. Toy building block 500 is devoid of any light source. Toy building block 500 is further devoid of any electronic component.

It will be appreciated that any toy building block, which includes at least one bore having at least one light conducting prong disposed therein is considered to be within the scope of the invention. As such, one of skill in the art may conceive of many other shapes and arrangements of such toy building blocks.

In some embodiments, a toy building block according to the present invention may be hemispherical, and may include a circular lower surface, a curved upper surface, and a circumferential and curved side surface. In some such embodiments, the bores may be throughgoing at all portions of the hemisphere, or may be throughgoing only at the apex of the hemisphere.

In some embodiments, a toy building block according to the present invention may be spherical, and may include a curved lower surface, a curved upper surface, and a circumferential and curved side surface. In some such embodiments, the bores may be throughgoing at all portions of the sphere, or may be throughgoing only at the apices of the sphere.

In some embodiments, a toy building block according to the present invention may be an upper end toy building block, such that none of the bores in the toy building block are throughgoing and light guided through the prongs is not visible from the top or sides of the toy building block. This arrangement of bores and prongs may exist in any shape of toy building block, including the block shapes described hereinabove, as well as spherical and hemispherical blocks.

In some embodiments, a toy building block according to the present invention may have a lower surface which has a smaller surface area than an upper surface thereof, and one or more angled side surface(s) connect the surfaces. In such embodiments, in areas that the upper and lower surfaces overlaps, the bores would be throughgoing and the prongs would extend from the bottom of the toy building block and to a height beneath the upper surface, such that a portion of the bore remains unfilled and the prong is visible from the top of the toy building block. In areas in which the upper and lower surfaces do not overlap, partial bores would extend from the body of the toy building block to the top surface thereof, and would not extend to the bottom surface of the toy building block. Prongs disposed in such partial bores would not extend from the bottom of the toy building block, and an upper end thereof would terminate within the bore beneath the height of the upper surface, while being visible from the top of the toy building block.

In use, toy building blocks according to the present invention are interconnected by placement of the prongs of a first, upper toy building block, within the bores of a second, lower toy building block disposed directly beneath the first block. The prongs of the upper block extend into the bores of the second block until they engage the upper end of the prongs of the second block, such that light guided through the prongs of the lower block continues to be guided through the prongs of the upper block, and is visible when viewing the structure from the upper surface of the upper block.

As described in detail hereinbelow, a toy building block according to the present invention, or a structure of such toy building blocks, may be placed above one or more light sources, such that light from the light source(s) may be guided through the prongs and may be visible from the top of the toy building block or of the built structure. As such, light may be used to guide the user which color block, or which type of block, to place above an already placed block, as explained in detail hereinbelow.

Reference is now made to FIGS. 8A, 8B, and 8C, which are perspective view illustrations of steps of building a three dimensional model using toy building blocks according to the present invention.

FIGS. 8A, 8B, and 8C show a building block base plate 600 which includes apertures, or anchoring locations, 602 for anchoring toy building blocks thereto, and is disposed above a plurality of illumination sources or above a crafting guiding system, for example as described in U.S. patent application Ser. No. 16/047,107 filed on Jul. 27, 2018, which is incorporated by reference as if fully set forth herein.

As seen in FIG. 8A, in a first construction step, light is illuminated from the crafting guiding system through some of the apertures 602, indicating the location and colors of toy building blocks to be placed on base plate 600. In the illustrated embodiment, the light is purple and forms the shape of a square 604.

In FIG. 8B, the user has placed toy building blocks according to the present invention as indicated in FIG. 8A over the base plate 600 in the locations indicated by illumination square 604, to form a square of suitable toy building blocks 606. The instructions for construction of the next layer of the structure are then displayed by the crafting system, and are visible via the light conducting prongs within the toy building blocks of square 606. In the illustrated embodiment, the instructions are provided by another color of light emanating from the toy building blocks of square 606, instructing the user to build a layer of a second color of toy building block, forming a square 608 that has smaller sides than square 606 and is concentric therewith.

In FIG. 8C, the user has placed toy building blocks of the second color over building block square 606 in the locations indicated by illumination square 608, to form a square 610 of toy building blocks of the second color. As such, the user has built a two-layer three-dimensional structure.
