FIELD OF THE INVENTION The present invention is generally related to a structure of toy bricks. More particularly, the present invention is related to the structure of toy bricks which can be combined together with the angle of forty-five or ninety degrees. A variety of appearances of the combined toy bricks can be provided by the variety of combinative modes.
DESCRIPTION OF THE PRIOR ART In general, there is a hollow base formed on a toy brick. The side walls around the toy brick define the hollow base of the toy brick with an open end. There is a certain superstructure formed on the base of the toy brick, and the combinative modes of the toy brick is determined by the configuration of the superstructure. When combining, the base of a toy brick is directly connected to the combination components set on the surfaces of other pieces of toy bricks, and the base of the toy brick is held by the combination components of other pieces of toy bricks and fixed upon the frictional forces between them. In general, the modification or variation of the design of toy bricks elaborated by the toy brick designers is emphasized on the holding means. Without any holding means, the variation of combinative modes between the toy bricks is limited. Further, the spaces inside the hollow base of the toy brick pieces can also be utilized to add certain holding element corresponding to the holding element on their surfaces to get further combinative modes. As illustrated by the FIG. 1 and FIG. 2 of the U.S. Pat. No. 6,554,676, an upper holding element and a bottom holding element of the toy brick are disclosed. The several combinative modes of the toy bricks utilizing the upper and bottom holding element are also showed in the FIG. 3 and FIG. 4 of the patent.
The combinative modes of the conventional toy bricks are generally limited to the alignment of the four orthogonal directions by their design of holding means, so the variation of the combinative modes is low. Consequently, several toy bricks which can be combined together beyond the angle of ninety degree are developed by the industry, such as the structure of toy bricks disclosed by U.S. Pat. No. 3,867,784. Their toy bricks can be combined together based on the alignment of the eight directions separated by the angle of forty-five degree, and the holding elements formed on the superstructure of the toy bricks are arranged with symmetrically crossing patterns. Two of the toy brick pieces can be combined together and fixed in eight relative directions which are held between the fins of one toy brick piece and the side walls the bottom of another toy brick piece. Although the novel design of the patented toy bricks provide the combination in eight directions, they did not own any holding element under the bottom of the toy bricks. The combinative modes of the toy bricks are thus limited by only the joint of the bottom walls and the holding element on the superstructure of the toy bricks. Therefore, the present invention provides an improved toy brick structure including novel design of holding element on the bottom of the toy brick for dissolving the problems existed in the prior arts.
SUMMARY OF THE INVENTION The present invention provides a toy brick structure which can be combined together with other identical ones by the angle of forty-five or ninety degrees, while the conventional toy bricks are generally able to be combined together by only the angle of ninety degree. The special holding elements formed on the bottom of the toy bricks of the present invention allow more combinative modes of the toy bricks of the present invention than the prior arts.
The toy brick structure of the present invention includes a box-shaped portion with a plurality of first holding elements formed thereon. The first holding element is composed of four elastic fins arranged symmetrically with crossing pairs. The bottom of the box-shaped portion includes a hollow open space, and the second holding element and third holding element are formed therein. The second holding element is composed of four protruding pins aligned in the four directions, wherein the number and position of the four protruding pins are corresponding to the first holding element formed on the box-shaped portion. The third holding element is composed of two holding pins and is disposed between every two second holding means. In the combination, the first holding element of the superstructure of the toy brick of the present invention are held by the second holding means, third holding means, and side walls of another identical one for fixing.
Other combination elements such as slots and tenon joints may be set on the side walls of the toy brick structures, hence lateral combinative modes among the plurality of toy bricks are provided.
Combination elements such as slots may be set on the upper walls of the toy brick structures for insertion, and further combinative modes are provided.

The upper wall 105 of the toy brick 100 includes a superstructure which is a configuration on the surface for the purpose of combining together the plurality of toy bricks. In the present invention, the configuration on the surface of the toy brick 100 includes a plurality of first holding element 107 for combining together by frictional holding with other toy bricks via their corresponding holding means. FIG. 2 is a pictorial view of the bottom portion of the toy brick 100 according to the embodiment of the present invention, and it shows the configuration of the box-shaped portion 101 and part of the side portion of toy brick of the embodiment of the present invention. As illustrated in FIG. 2, the bottom portion of the box-shaped portion 101 includes a hollow open space with the second holding element 109 and the third holding element 111 formed therein. The second holding element 109 and/or the third holding element 111 are utilized to form various combinative modes between other identical toy bricks via the frictional holding with the corresponding first holding element 107 on the upper walls 105 of the other toy bricks. The detailed structures and combinative modes of the second holding element 109 and the third holding element 111 will be introduced and illustrated in the following embodiments.
FIG. 3a and FIG. 3b are the top view and the bottom view of the toy brick according to the embodiment of the present invention. As the square area presented by dashed lines illustrated in FIG. 3, the upper wall 105 of the toy brick 100 in the embodiment includes two first holding elements 107 formed simultaneously with the forming of the superstructure of the toy brick 100. In this embodiment, the two first holding elements 107 are arranged with identical distances d1, and each of the first holding element 107 is composed of four fins 113. The four fins 113 are arranged symmetrically with crossing pairs aligned on the diagonals of the square area represented by dashed lines of the first holding element 107. The near ends of fins 113 are arranged with the identical distances d2, and the far ends of fins 113 are pointed to the four corners around the upper wall 105, respectively. It should be noticed that the above-mentioned arrangements of the two first holding elements 107 are just for illustration. In other embodiments, there may be two or more first holding element 107 set on the single toy brick 100, and the first holding element 107 can be arranged in array but not single row or column to increase the variety of the combinative modes of the toy bricks. The configuration of the bottom portion of the toy brick, as shown in FIG. 3b, includes the second holding element 109 and the third holding element 111 within the hollow space of the box-shaped portion 101. In the present invention, the number of the second holding element 109 is identical to the number of the first holding element 107 formed on the upper wall 105. For example, FIG. 3a shows two first holding elements 113 formed on the toy brick 100, so that the bottom portion of the toy brick also includes two corresponding second holding elements 109. Therefore, the more the number of the first holding elements 113, the more the number of the second holding elements of 109. Further, the position of the second holding element 109 is also corresponding to the position of the first holding element 113. For regular geometric combination, both the holding elements are matched with the same center point (i.e., the center point of the square area represented by dashed lines). In the present invention, the second holding elements 109 are composed of four arch protruding pins 115. As illustrated, the arch protruding pins 115 are arranged in the four directions of up, down, left, and right, and each of the arch protruding pins 115 faces one of the inner walls around the box-shaped portion 101. Each of the distance between the arch protruding pins 115 and the nearest inner walls is d3, and the distance approximates the width of the fins 113 of the first holding element 107 according to this embodiment for appropriate effect of frictional holding. Furthermore, the distance d4 between every two neighbor protruding pins 115 has to be greater than the width of fins 113 for receiving the fins 113 without shifting. In addition, the third holding elements 111 are arranged between the two second holding means. As showed in FIG. 3b, the third holding elements 111 are set on the mid-line of the side walls of the box-shaped portion 101, and the second holding elements 109 are symmetrically arranged on the both sides. In the present invention, the third holding elements 111 are composed of two curved holding pins 117. As illustrated, the curved holding pins 117 are arranged in pair, and they face the two longer side walls of the box-shaped portion 101, respectively. In this embodiment, the width of holding pin 117 approximates the distance do between the two neighboring fins 113 of the first holding element 107 illustrated in FIG. 3a for appropriate frictional holding. The distance d5 between the holding pins 117 and the nearest inner walls approximates to the width of fins 113 of the first holding element 107 for the appropriate frictional holding. The novel holding element set on the toy brick 100, including the first, the second, and the third holding element 107, 109, and 111, can carry out more amounts of combinative modes between the toy bricks than the amount prior art can provide. The details of the embodiments will be described bellow.

The illustrations of the embodiment in FIG. 5a-5d describe the combinative modes of the toy bricks of the present invention with the angle of forty-five degree. The combination of the toy bricks provided by the present invention includes further combinative modes and appearances which can not be achieved by the prior arts, since the toy bricks of the present invention own the novel second holding element 109 and the third holding element 111.
The above-mentioned design of toy bricks allows the toy bricks of the present invention to be combined together with the identical ones and be combined together with the toy bricks provided by prior arts, and the application is widely broadened. FIGS. 6a and 6b illustrates the schematic diagrams of the combination between the toy bricks 116 of the present invention and the conventional toy brick 118 with the angle of ninety degree. As illustrated, there are eight round tenons 120 formed on the upper portion of the conventional toy brick 118, and these tenons 120 are arranged in arrays with the identical distance d6. Combined with the angle of ninety degree as illustrated in FIG. 6a, the protruding pins 115 of the second holding element 109 on the bottom of the toy brick 116 of the present invention will be inserted into the two tenons 120, and the effect of frictional holding is achieved. The width of the protruding pin 115 approximates to the distance d6 between tenons 120. For better effect of fixing, blades 122 can be formed on the corner of the inner side walls of the toy brick 116. One end of the tenon 120 of the toy brick 118 is intended to be stuck by the two protruding pins, and the other end of the tenon 120 is stuck by a blade 122. Via the holding provided among the tenons 120, protruding pins 115, and blades 122, the toy brick 116 of the present invention can be combined with the conventional toy brick 118 with any orthogonal angels (including vertical and horizontal directions). FIG. 6b illustrates another combinative mode of the present invention. In this embodiment, the effect of fixing is achieved by the holding between the toy brick 116 and the two tenons 120.
In other embodiments, there are other various elements can be formed on the surface in addition to the first holding element 107 for providing other various combinative modes. As illustrated in FIG. 7a, it illustrates the exemplary embodiment of the lateral combination of two toy bricks 100a and 100b via their slots and tenon joints. As illustrated, there are two slots 119 formed on the two longer side walls of both the toy bricks 100a and 100b, and the slots 119 cross through the longer side wall 103a for connecting with the slot (not shown) on the other longer side wall. In this embodiment, the tenon joint 121 is a cylindrical component with the flanges 121b on the two ends and the mid-position, and its length is the sum of the width of toy brick 100a and 100b. When inserting the tenon joints 121 into the corresponding slots 119 on the two toy bricks, the flanges 121b on the tenon joints 121 are engaged with the grooves on the slots 119 of the toy bricks for fixing. As illustrated in the right part of FIG. 7a, the longer side walls of the toy bricks will contact with each other, and the end walls 103a are arranged in alignment with each other. The plurality of toy bricks can be lateral combined via the design of the tenon joints 121 and slots 119 for providing more combinative modes. In other embodiments, the tenons 124 and slots (not shown) can be further formed on the longer side walls of the toy bricks 100a and 100b for combination. Via the engagement of the tenons and slots of the two toy bricks, the toy bricks can be lateral combined without above-mentioned additional tenon joints 121.
Further, other slots can also be formed on the upper walls of the toy bricks for further combinative modes. As illustrated in FIG. 7c, there is a slot 123 formed between the two first holding elements 107 of the toy brick. Being similar to slot 119, there are also grooves formed of the slot 123 for engaging with other tenon joints. As illustrated in FIG. 7c, a flag type insert 125 is inserted into the slot 123 for engagement, and thus further combinative modes are provided via the design on the upper portion of the toy brick. The insert 125 can be implemented as any type of accessories of toy bricks such as flag, number, and/or holder type accessories or appearances for providing more combinative modes.
