Description

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 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.

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. 3 a and FIG. 3 b 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. 3 b, 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. 3 a 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 d₄between 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. 3 b, 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 d_obetween the two neighboring fins 113 of the first holding element 107 illustrated in FIG. 3 a for appropriate frictional holding. The distance d₅between 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.
