Abstract:
A rectangular stackable brick is provided having substantially parallel opposing top and bottom surfaces, substantially parallel opposing side surfaces and substantially parallel opposing end surfaces. The length of the brick is approximately twice the width of the brick so that the top and bottom surfaces each define first and second square regions. The top surface includes a first column which projects upwardly from the center of a first square region and a second column which projects upwardly from the center of a second square region. The bottom wall of the brick includes a recess sized and configured for receiving the first and second columns. The recess extends from an end wall along the center of the length of the brick sufficiently far so that the brick can be stacked upon other bricks of like construction.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to bricks for structural objects such as botanical gardens, outside furnaces, stairs and walls, etc.  
           [0002]    Bricks are typically rectangular with the six flat sides. By stacking numerous amounts of bricks, one can construct many structures. Stacking procedures include English stacking, French stacking, Holland stacking, German stacking, Horizontal stacking and many other stacking procedures may be used. In any stacking procedure, the bricks are stacked up/down, left/right or front to back with mortar between the adjacent bricks.  
           [0003]    However, as mentioned earlier, since the stacking procedures of up/down, left/right or front/back requires accuracy with a sufficient amount of mortar to intervene between the adjacent bricks, some skill is required of the workers. As a result of the recent years&#39; gardening boom, more and more persons attempt to DIY (Do It Yourself) when constructing garden pergolas or outside furnaces for barbeques. Lack of skill makes these construction projects extremely difficult and time consuming.  
           [0004]    The purpose of this invention is to construct structural objects such as barbeques, the lining of the botanical garden and various types of walls. The invention does not require any skills for the workers to stack the bricks up/down, left/right or front/back as the stacking is simple and accurate. Moreover, highly unrestricted level of stacking can offered by the stackable bricks corresponding to the intended objects being constructed.  
         SUMMARY OF THE INVENTION  
         [0005]    The present invention addresses the aforementioned disadvantages by providing a brick having top and bottom surfaces, first and second end surfaces, and first and second side surfaces. It is an object for this invention to utilize this brick to construct various structural objects along with the procedures for stacking. With reference to the top and bottom surfaces, the ratio of the width is approximately half ({fraction (1/2)}) the length which forms a rectangular stackable brick. Since the length of the brick is twice its width, the top and bottom surfaces each include two equal sized square regions. On the brick&#39;s top surface, there are two (2) columns or cylindrical shaped built-in convex portions that are located in the center of each the two (2) equally divided squares. In addition, the brick includes a built-in concave portion, or recess, formed on the bottom surface of the brick. The recess extends along the length of the bottom surface of the brick from one of the end surfaces toward the opposing end surface. The recess extends sufficiently far so that the recess will receive the two columns of a like brick when stacked vertically.  
           [0006]    This present invention also includes the procedure to assemble the stackable bricks to form a structural object. The procedure includes aligning multiple amounts of the build-in convex surfaces in a line. The bottom surface with the build-in concave surface should be placed approximately half-way from the center to overlap with each other. The built-in convex portion and the bottom built-in concave portion will fit accordingly as it defines the characteristics of a stackable brick procedure.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0023]    While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described the presently preferred embodiments of the invention, with the understanding that the present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.  
         [0024]    The following will be an illustrated operation form and the explanation of the operational examples. As FIGS. 1 and 2 illustrate, the first stackable brick  1  is a rectangular figure. In comparing the top and bottom side  1   a ,  1   b  of the longer side, the ratio of the width is approximately {fraction (1/2)} the length. Preferably, the longer side length L 1  is 210 mm and the width length L 2  is 105 mm. The thickness for T of brick  1  is 65 mm.  
         [0025]    On the top surface  1   a  of brick  1 , there are (two) 2 approximate cylindrical shaped built-in convex portions  2 A,  2 B that are formed in the center of the 2 equally divided squares. On the built-in convex portion  2 A,  2 B, the diameter of the base edge d  1  is preferably approximately 51 mm. Meanwhile, preferably the diameter of the top edge portion d  2  is approximately 46 mm and the height of the convex portion  2 A,  2 B(H) is approximately 9 mm.  
         [0026]    The bottom side  1   b  of brick  1  has a built-in concave portion  3  extending from the left edge to the right edge portion which corresponds directly with the opposite side where the built-in convex portion  2 A,  2 B are positioned. The width of the opening W  1  is approximately 53 mm, base portion width W  2  is approximately 48 mm and the depth D is approximately 11 mm on the built-in concave portion  3 . The built-in concave portion  3  with the built-in the convex portion  2 A,  2 B Set, the semi-circular wall edge  3   a  and the adjacent outer surface side  2   b  of the built-in convex portion  2 B is proportionally lengthed to correspond with the built-in concave  3 . In detail, the length from the base edge  3  to the top edge wall portion  3   a,  L 3  is approximately 188 mm. On the right side of the built-in convex portion  2 B and the outer surface side  2   b,  there is an approximate 4 mm gap in between. Hence, there may be an instance where brick  1  is used with the length approximately 1:1 times bigger.  
         [0027]    As FIGS. 3 and 4 illustrate, the second stackable brick  4  is the first stackable brick  1  where the built-in concave portion  2 A,  2 B are not formed on top side  1   a,  namely, the top side  1   a  is a flat surface where the other portions are exactly the same as the first stackable brick  1 . Since the mark is the same as the first stackable brick, the explanation will be omitted.  
         [0028]    As FIGS. 5 and 6 illustrate, the third stackable brick  5  is the first stackable brick  1  where the built-in concave portion  3  is not formed on the bottom side  1   b.  Namely, the bottom side  1   b  is a flat surface where the other portions are exactly the same as the first stackable brick  1 . Since the mark is the same as the first stackable brick, the explanation will be omitted.  
         [0029]    As FIG. 7 illustrates, the fourth stackable brick  6  is the right half portion of the longer side equivalent to the first stackable brick  1  divided in half. In detail, the built-in convex portion  2 B is placed in a central position of the top surface  1   a  of the brick  6 . On the bottom side  1   b  from the left edge to the right portion, the built-in concave portion  23  is established.  
         [0030]    As FIG. 8 illustrates, the fifth stackable brick  7  is the right half portion of the longer side of the second stackable brick  4  divided in half. In detail, the top side  1   a  is a flat surface of brick  7 , the bottom surface  1   b  from the left edge to the right edge portion, the built-in concave portion  33  is established.  
         [0031]    As FIG. 9 illustrates, the sixth stackable brick  8  is one portion of the longer side of the 3 rd  stackable brick  5  divided in half. In detail, the built-in convex portion  2 B is placed in a central position of the top side  1   a  of brick  8 . The bottom side  1   b  is determined to be a flat surface.  
         [0032]    [0032]FIG. 10 illustrates a first stacking procedure by utilizing the brick  1  and aligning multiple amounts of brick  1 A in a horizontal direction. Brick  1 B is placed on the top for stacking above adjacent brick  1 A. The bricks should be placed where the top brick  1 B will overlap with the bottom brick  1 A from the center half of the long side of  1 B. Hence, the built-in convex portions  2 A and  2 B of brick  1 A will fit into the concave portion  3  of top brick  1 B.  
         [0033]    Yet, with the stacking procedure mentioned earlier, the brick  1 A which is positioned as the very bottom layer may be exchanged with the third brick  5  which has the bottom side  1   b  as a flat surface will be more stable when stationed to the ground in comparison to the first brick  1  with the bottom surface  1   b  having a built-in concave portion  3 .  
         [0034]    [0034]FIG. 11 illustrates a second stacking procedure using the brick  1  where multiple amounts of brick  1 A are placed horizontally in an arc position. Brick  1 B is placed on the top of brick  1 A for stacking, along with the brick  2 A above brick  1 A. Brick  2 B will engage the top of brick  1 B with the bottom surface  1   b  having the built-in concave portion  3  receiving a concave portion of the next lower brick. The multiple amounts of brick  1 A should be covered by the multiple amounts of top brick  1 B in an arc position. Consequently, for instance, this stacking procedure for stacking many layers of bricks may be used to construct the lining of the botanical garden, assuming that the lining will be stacked in a parallel with the bottom brick  1 A, but, to be placed in a horizontal direction with a slightly different angle.  
         [0035]    When the top brick  1 B along with the bottom brick  1 A is placed in a horizontal direction with a slightly different angle, the bottom brick  1 A with the top surface  1   a  having the built-in convex portions  2 A,  2 B placed directly adjacent to the half circular top edge wall portion  3   a  of the built-in concave portion  3  on top brick  1 B. Since the top brick  1 B may be moved to the fixed angle, the stacking of the bricks is simple, yet accurately performed. Moreover, by this stacking procedure, the third bricks may be replaced with the first brick  1  placed on the very bottom layer in order to achieve a higher level of stability on the very bottom layer brick when placed on the ground level.  
         [0036]    [0036]FIG. 12 illustrates the third stacking procedure in using the brick  1  in aligning multiple amounts of brick  1 A in the width direction. Brick  1 B is placed on the top for stacking along with the bottom  1 A and positioned in a direct cross where the bottom brick  1 B will overlap with the bottom brick  1 A from the center of  1 B. Hence, both adjacent bottom brick  1 A with its top surface  1   a  along with one of the built-in convex portion  2 A will fit into the top brick  1 B with the bottom surface  1   b  having the built-in concave portion  3 .  
         [0037]    Again, as for this stacking procedure, the third brick  5  may be replaced with the first brick  1 A placed on the very bottom layer in order to achieve a higher level of stability on the bottom when placed on the ground.  
         [0038]    [0038]FIG. 13 illustrates the fourth stacking procedure using the first brick  1 , placing a different first brick  1 B directly on the top of the first brick  1 A, the bottom brick  1 A with the top surface  1   a  having two built-in convex portion  2 A,  2 B will fit with the top brick  1 B with the bottom surface  1   b  having the built-in concave portion  3 . Again, as for this stacking procedure, the third brick  5  may be replaced with the first brick  1 A positioned on the very bottom layer.  
         [0039]    [0039]FIG. 14 illustrates wall  9  constructed by using the first stacking procedure. In detail, the first layer from the ground is placed in a horizontal direction using the first brick  1 . After placing the fourth stackable brick  6 , stack the second layer with the first brick  1 . Next, use the same stacking procedure as the first layer for the third layer and the same stacking procedure as the second layer for the fourth layer. Then, for the last layer, place the fifth stackable brick  7  on each end and in between both brick  7 , align the second stackable brick  4  in a horizontal direction. From this, wall  9  will be constructed. The first layer using the first brick  1  may be replaced with the third stackable brick  5  which the bottom side  1   b  a flat surface. The fourth stackable brick  6  may be replaced with the first layer brick is placed more stable on the ground level.  
         [0040]    On the all brick stacking procedure mentioned above, the structural object does not need mortar to be placed in between the adjacent bricks for construction. However, mortar may be used if necessary to make sturdier structural objects.  
         [0041]    [0041]FIG. 15 illustrates a barbeque or outside furnace  11  constructed basically by using the first to sixth brick  1 ,  4 - 7  with the first stacking procedure described above. The outside furnace  11  has mortar between adjacent bricks.  
         [0042]    Although the present invention has been described with reference to the preferred embodiments, workers killed in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
