Description




BACKGROUND OF THE INVENTION




This invention relates to a modular block and more particularly to a modular block for constructing a retaining wall or other similar landscaping structure.




Retaining wall structures and similar landscaping structures have been constructed from various materials. Examples of such materials include railroad ties, steel rods or bars, poured concrete, rocks, stones, and preformed concrete blocks. In recent years the preformed concrete blocks have been popular because such blocks can be mass produced and are relatively inexpensive. Additionally, such blocks are as durable as concrete and have various finishes and colors. Even though these blocks are relatively inexpensive, they typically require complex installations to construct various landscaping structures. Further, due to the weight of the blocks, they are sometimes difficult to carry or handle when constructing a landscaping structure. Frequent hand or finger injuries occur when handling these blocks. Additionally, more than one type of block is typically required to construct a structure. Homeowners and commercial landscapers will avoid using numerous blocks due to the difficulty encountered in building a landscaping project or structure.




The present invention is designed to obviate and overcome many of the disadvantages and shortcomings associated with present wall blocks. In particular, the present invention is a modular block which may be used to easily construct various landscaping structures. Moreover, the modular block of the present invention can be employed to construct various complex landscaping structures and is easier to handle than currently available stones or blocks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring now to the drawings, wherein like numbers refer to like items, number


10


identifies a preferred embodiment of a modular block


10


constructed according to the present invention. With reference now to

FIG. 1

, the modular block


10


has a triangular shaped block body


12


which comprises a front face or side


14


, a top side


16


, a bottom side


18


, and a pair of sides


20


and


22


with all of the sides


14


-


22


forming the triangular shaped block body


12


. The front face


14


has an irregular surface which resembles a natural product such as rock or stone and is known as a split face. The manner in which the split face is formed will be described herein. The block


10


also has three corners


24


,


26


, and


28


which are beveled which help prevent the block


10


from being broken or chipped during manufacturing, transportation, storage, or handling of the block


10


. A passage


30


is also formed in the block


10


and runs through the entire body


12


between the top side


16


and the bottom side


18


. The passage


30


allows a bar or pin to be inserted therein for use in constructing a landscaping structure, as will be explained.




The sides


20


and


22


are generally of the same dimensions. The top side


16


and the bottom side


18


are of the same general dimensions. The top side


16


and the bottom side


18


are also parallel to each other and separated from each other by the dimensions of the sides


20


and


22


and the front side


14


.





FIG. 2

shows a perspective view of a modular block


40


is shown wherein the block


40


is formed by splitting the block


10


into two separate blocks with one of the resulting blocks being the block


40


. The block


40


has a triangular shaped block body


42


which comprises a pair of sides


44


and


46


having split faces


48


and


50


, respectively, a top side


52


, a bottom side


54


, and a back side


56


. The sides


44


,


46


,


52


,


54


, and


56


all form the triangular shaped block body


42


. Although not shown with this particular block


40


, it is also possible to manufacture a block similar to the block


40


with the one difference being that the similar block has the passage


30


which was shown in FIG.


1


. The split faces


48


and


50


may be used to form a square corner when using the block


40


to form a wall structure. The back side


56


is actually the side


22


of the block


10


shown in FIG.


1


and the side


46


having the split face


50


is a portion of the side


14


of the block


10


.




With reference now to both

FIGS. 3 and 4

, a modular ingot


100


is illustrated which is used to form the blocks


10


and


40


. The modular ingot


100


is generally rectangular in shape and has four sides


102


,


104


,


106


, and


108


, a bottom side


110


, and a top side


112


. The bottom side


110


has a first or primary score line


114


and a pair of secondary score lines


116


and


118


. The primary score line


114


is used to split the ingot


100


into two complimentary blocks


120


and


122


. The two blocks


120


and


122


correspond to the modular block


10


. The two blocks


120


and


122


each have one split face which are similar to the split face formed on the front side


14


of the block


10


. The secondary score line


116


is used to split the block


120


into two more complimentary blocks


124


and


126


with the block


126


being similar to the block


40


and the block


124


being similar to the block


40


with one difference being the block


124


having a passage similar to the passage


30


. The blocks


124


and


126


each has two split faces similar to the split faces


48


and


50


of the block


40


. Additionally, the secondary score line


116


is used to split the block


120


into two more blocks


128


and


130


which are also each similar to the block


40


. Again, the blocks


128


and


130


will each have two split faces.




Each of the sides


102


,


104


,


106


, and


108


of the ingot


100


has a hand hold


132


,


134


,


138


, and


136


respectively formed therein. The hand holds


132


and


134


are provided in the block


120


for grasping the block


120


. Additionally, the hand holds


136


and


138


are incorporated within the block


122


for the same function. Even before the ingot


100


is split to form the blocks


120


and


122


, all of the hand holds


132


-


138


may be used to facilitate lifting and carrying the ingot


100


. The hand holds


132


-


136


may be of any shape which will facilitate an individual to better grasp or hold any of the blocks


10


or


40


. As shown in

FIG. 3

, the hand holds


132


-


136


are of a generally rectangular shape having a tapered interior. The ingot


100


also includes a pair of passages


140


and


142


, similar in construction to the passage


30


, which are positioned on opposite sides of the primary score line


114


. The passages


140


and


142


are adapted to receive rods or pins for use in constructing a landscaping structure.




The primary score line


114


runs the entire diagonal of the ingot


100


and ensures that the ingot


100


will be split into the two complimentary blocks


120


and


122


. The secondary score lines


116


and


118


are formed such that they do not run the entire diagonal of the ingot


100


. As discussed previously, the secondary score lines


116


and


118


are used to split the blocks


120


and


122


into the complimentary blocks


124


,


126


,


128


, and


130


.




The side


104


corresponds to the side


20


of the block


10


and the side


102


corresponds to the side


22


. The sides


102


-


108


are generally of the same dimensions. The bottom


110


and the top are of the same general dimensions and are also parallel to each other and separated from each other by the dimensions of the sides


102


-


108


. The ingot


100


does not have any split faces until the ingot


100


is separated into the two blocks


120


and


122


or the complimentary blocks


124


,


126


,


128


, and


130


.




Referring in particular to

FIG. 4

, the ingot


100


is shown being split apart into the block


122


and the block


120


is shown being split into the two blocks


124


and


126


. As discussed above, the block


122


is similar to the block


10


and the blocks


124


and


126


are each similar to the block


40


. The block


122


is shown to have a split face


144


and the sides


106


and


108


forming a generally triangular shaped body


146


. The block


126


is depicted having a first split face


148


and a second split face


150


. The split faces


148


and


150


and the side


102


form the triangular shaped block


126


. Further, the block


124


also has a first split face


152


and a second split face


154


. Again, the split faces


152


and


154


and the side


104


form the triangular shaped block


124


. As can be appreciated, a single ingot or block


100


may be manufactured or formed and then split into either two blocks


120


and


122


or four blocks


124


,


126


,


128


, and


130


or one block


120


and two blocks


128


and


130


.




With reference again to both

FIGS. 3 and 4

, the modular ingot


100


also has formed on the bottom side


110


offset pockets


160


,


162


,


164


, and


166


. The pockets


160


-


166


are generally rectangular in shape and cross section and span across only a portion of the bottom side


110


. The offset pockets


160


-


166


are used to construct a retaining wall structure in a tiered formation with each tier being set-back or offset from each other. The pockets


160


-


166


provide for a predetermined or preselected distance that each of the tiers will be set-back.




The ingot


100


also has beveled or generally V-shaped corners


168


,


170


,


172


, and


174


. The purpose of the corners


168


-


174


is to prevent the ingot


100


from being broken or chipped during either manufacturing, transportation, storage, or handling. Additionally, the corners


168


-


174


are used to be or to form the beveled corners


24


,


26


, and


28


of the block


10


.




A top view of the modular ingot


100


is illustrated in FIG.


5


. The ingot


100


comprises the top side


112


and the sides


102


-


108


. The passages


140


and


142


are also shown. Although only two passages


140


and


142


have been depicted and discussed, it is also possible and contemplated to have other similar passages formed in the ingot


100


. It is also possible to manufacture a block not having any of the passages


140


and


142


. In this case a modular block not having any passages could be used as a capstone for a landscaping structure.





FIG. 6

shows a retaining wall structure


200


which may be constructed using the modular block


10


of the present invention. The retaining wall structure


200


may be formed using a number of individual courses


202


,


204


, and


206


of the blocks


10


to build the structure


200


to any given height. The blocks


10


may be stacked on top of each other to form the wall structure


200


. Other designs or shapes for various landscaping structures may be formed by using the blocks


10


or in combination with the blocks


40


. Construction of the wall


200


is accomplished by using known construction methods. For example, a trench area may be excavated which approximates the size of the blocks


10


. Footing material may be placed into the trench area to be compacted and leveled. A first layer or course


202


of the blocks


10


are then laid into the trench and then the ensuing individual course


204


of the blocks


10


is laid on top of the first course


202


. To finish the wall structure


200


, a top or cap row or course


206


may be formed by placing the blocks


10


over the course


204


. Additionally, if the wall structure is a retaining wall, it is known to use material such as geogrid to help hold the soil retained by the wall in place. In this situation, the passage


30


may have a rod inserted therein and the geogrid material, which includes holes, can be placed through the rod. This helps to keep the geogrid in place and the weight of the block


10


also helps to hold the geogrid material in place.




A landscaping structure such as a straight wall structure


210


is shown in

FIG. 7

to consist of the blocks


10


being placed side by side. In this manner, the straight wall structure


210


is able to have a finished look on both sides of the structure


210


. In particular, the split faces


14


of the blocks


10


are presented on both sides of the structure


210


. The blocks


10


may be stacked on top of each other to form the wall structure


210


of any desired height. Additionally, more blocks


10


may be used to build the wall structure


210


to any given thickness or height.




As can be appreciated, the ingot


100


of the present invention is formed by using a mold (not shown). The ingot


100


can be easily manufactured by casting or forming the modular ingot


100


using a suitable mold. Generally, the process entails molding the modular ingot


100


with a mixture of cement and water and other materials. The modular ingot


100


is casted by compressing and vibrating the mixture in a mold by the application of pressure to the mixture in a mold box in a block machine or similar machine. Once the ingot


100


is formed the ingot


100


may be cured through any method known in the art. For example, curing may take the form of air curing for a number of days or steam curing, but normally one day is allowed or needed for cure. Once cured, the ingot


100


may be split into pairs or the two complimentary blocks


120


and


122


by splitting along the score line


114


. Some methods of splitting include using a manual chisel and hammer, a hydraulic splitting machine, or any other machine which can accomplish splitting. The groove or score line


114


provides a weak point which facilitates the splitting of the ingot


100


. Additionally, splitting creates the split face surface


14


of the block


10


with the split face surface


14


resembling or mimicking some types of natural stone or rock.




Many combinations of concrete mixtures may be employed in manufacturing the ingot


100


. Some considerations in determining the particular concrete mixtures include compression strength requirements, density, and shrinkage adsorption. Further, the costs of the materials, such as sand, gravel, cement, pigment additives, and rock have an impact on the mixture to be used. For example, gravel may be cheaper than river rock in some areas of the country and the ingot


100


may be formed of a mixture having more gravel than rock due to the difference in cost. The ingots


100


may be constructed with colored pigments to form different colored blocks. It should be recognized that the ingot


100


of the present invention may be constructed of various materials which are available. Preferably, the blocks


10


or


40


will be of relatively lightweight so that the blocks


10


or


40


can be easily manufactured, stored, transported, and stacked.




As can be appreciated, the blocks


10


and


40


of the present invention may be used for both commercial and residential use in building various landscape structures. The hand holds


132


-


138


provide an area for a commercial landscaper or a homeowner to easily grasp, carry, handle, stack, and place any of the blocks


10


or


40


. The hand holds


132


-


138


are very useful and from a safety standpoint reduce hand and finger injuries related to grasping, handling, and placing the blocks


10


and


40


. The dimensions of the ingot


100


are preferably


16


inches square which allows three of the ingots


100


to be placed side by side to arrive at a four foot or 48 inch span which is adapted to fit on a four foot pallet. This allows the ingots


100


to be stacked and transported on a four foot square pallet. This also means that no special or retrofitted pallets are required to stack or transport the ingots


100


. Further, if the ingot


100


is split into either of the modular blocks


10


or


40


during the manufacturing process, then such resulting blocks


10


or


40


may also be stacked on a pallet for storage and transportation. In particular, eighteen of the blocks


10


may be stacked as a layer on a four foot square pallet or thirty-six of the blocks


40


may be stacked as a layer. It is also possible to stack combinations of the blocks


10


or


40


together on the same pallet.




Other advantages associated with the use of the modular blocks


10


and


40


include the reduced number of different components or parts which need to be manufactured, transported, storied, or inventoried. Since the ingot


100


can yield two to four different blocks from a single ingot or mold, manufacturing costs are significantly reduced. In particular, only one mold is required which can greatly reduce manufacturing costs. Being able to use the same block as the capstone also reduces the number of different kinds of blocks that must be manufactured to be used to build landscaping structures. The blocks


10


and


40


are also easy to install or build with and have multiple uses for various landscaping projects or structures. Examples of other landscaping projects or applications which may be constructed using the blocks


10


and


40


include circle planter boxes and other stone structures of over 16 inches in diameter such as tree rings, BBQ pits, or tetra ponds, steps, free standing walls, raised patios, patio barrier walls, fence posts, and stone fences.




Another particular aspect of the modular blocks


10


and


40


is that these blocks may be tumbled to give a natural appearance to the blocks. Once the ingot


100


is formed and split into either the blocks


10


or


40


, the resulting blocks are put into a machine which tumbles the blocks together. After the tumbling process is complete, the blocks


10


or


40


may be used in the same manner as above described. Tumbling enhances the appearance of the blocks


10


and


40


and this allows the blocks to be sold at a premium.




From all that has been said, it will be clear that there has thus been shown and described herein a modular block which fulfills the various objects and advantages sought therefor. It will become apparent to those skilled in the art, however, that many changes, modifications, variations, and other uses and applications of the subject modular block are possible and contemplated.
