Similarly, the word “another” may mean at least a second or more.

[0026] As used in this specification and claim(s), the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “include” and “includes”) or “containing” (and any form of containing, such as “contain” and “contains”), are inclusive or open-ended and do not exclude additional, un-recited elements.

[0027] An illustrative embodiment of a block wall 10 is shown in FIG. 1. The block wall 10 is made of a plurality of concrete blocks 12 and 14 according to first and second illustrative embodiments.

[0028] In FIG. 1, the wall 10 and blocks 12 and 14 are shown from below to better show the inventive features thereof. However, the first row of blocks 12 and 14 of the wall 10 sits firmly on the ground or on a foundation like for any conventional block wall.

[0029] The wall 10 can be used, without limitations, as a retaining wall, a perimeter fence, a garden wall/outside decorative wall, etc.

[0030] As will become more apparent upon reading the following description of the blocks 12 and 14, they can be assembled to form a block wall having another configuration than illustrated in FIG. 1.

[0031] In all cases, abutting and piling a plurality of such wall blocks 12 and 14, yields a block wall 10 automatically provided with constantly shaped decorative joints.

[0032] With reference to FIG. 2, a concrete wall blocks 12 according to a first illustrative embodiment will now be described.

[0033] The wall block 12 is a generally rectangular body having a front decorative face 16, a back face (not shown) opposite the front face 16, first and second lateral faces 18 and 20, and top (not shown) and bottom 22 faces.

[0034] The block 12 includes two (2) spacers 24 and 26, located respectively on the first lateral face 18 and on the bottom face 22, which are both adjacent the decorative face 16. The spacers 24 and 26 result from U-shaped depressions 28 and 29 on respectively the first lateral and bottom faces 18 and 22.

[0035] As can be seen in FIG. 1, abutting side-by-side and piling on top of each other such block 12 (or block 14) yields lateral and longitudinal decorative joints 30 and 32, the width thereof being defined by the width of the depressions 28 and 29. According to the illustrative embodiment, the width of the depressions is five 5 mm but may range between 1 mm and 20 mm.

[0036] While the width of the depressions 28 and 29 is the same laterally and longitudinally, a wall block according to another illustrative embodiment (not shown) can be provided with a U-shaped depression having different sizes laterally and longitudinally.

[0037] The depressions 28 and 29 have a depth that is sufficient to yield the decorative joint. According to the illustrative embodiment, the depth of the depressions 28 and 29, which is also the height of the spacers 24 and 26, is 30 mm, but may range between 10 mm and 100 mm.

[0038] The spacer 26 has a bottom surface 34 that is parallel to the top face so as to yield a stable contact therebetween, when two or more blocks 12 are piled for storage or shipping.

[0039] FIG. 4 illustrates a shipping pallet 36 comprising identical wall blocks 12. As can be seen in this Figure, the peripheral edge 38 of the decorative face 16 of two adjacent blocks 12 on the pallet 36 are prevented from coming into contact by the groove 32 formed by the depression 28. This prevents the decorative face 16, which is the main visible face of the block 12, and therefore of the wall 10, from being chipped during transport, thereby preserving its integrity and appearance.

[0040] While the spacers 26 and 28 have rounded peripheral edges 40 and 42.

[0041] The block 12 according to the first illustrative embodiment is the result of a molding process. More specifically, the block 12 results from a molding process that involves a mold, including a plurality of cavities, each to form a block 12, (not shown), is the mold being removed from the top after molding. This limits the shape of any spacer created on the periphery of the block using such process.

[0042] According to such a manufacturing process for the block 12, the front decorative face 16 corresponds to the top face of the block 12 within the mold cavity. This further gives the option of filling the mold cavities with two (2) layers of concrete, a back mix, and a front color mix, the later providing the decorative face 16 of the resulting block 12 with some coloration.

[0043] The same molding process provides the further option of adding markings on the decorative face 16.

[0044] While the blocks 12 on FIG. 1 are shown having generally the same dimension, similar rectangular blocks that have different sizes or proportions can also be provided, which could be used to add aesthetic variability in raising a wall.

[0045] A wall block 14 according to a second illustrative embodiment will now be described with reference to FIG. 3. Since the wall block 14 is similar to the wall block 12, only the differences therebetween will be described herein for concision purposes.

[0046] The rectangular wall block 14 has dimensions similar to the rectangular block 12. While this similarity is not necessary, this add to the illusion that all blocks 12 and 14 are simply regular rectangular shaped blocks without any spacers.

[0047] However, compared to the block 12, the block 14 does not include a spacer 24 on any of its lateral side 18 or 20 and includes only spacer 26 on its bottom side 22.

[0048] As can be seen in FIG. 1, such a configuration of the block 14 renders the block 14 suitable to create wall corner, which can be achieved by piling the blocks 14 while alternating their orientation ninety (90) degrees. Such piling, in addition to their side-by-side abutment with adjacent blocks 12, yields the same lateral and longitudinal decorative joints 30 and 32 as described hereinabove, while preventing any spacer from being visible on the resulting wall 10. The same can be said of the use of block 14 as coping blocks.

[0049] FIG. 5 illustrates a wall block 44 according to another illustrative embodiment. Since the block 44 is very similar to the block 14, only the difference therebetween will be described herein in more detail for concision purposes.

[0050] The only difference between the blocks 14 and 44, is that the peripheral edge 46 of the decorative face 48 thereof is chamfered, which can be obtained, for example, by modifying the mold used to make the blocks 14 as described hereinabove. Providing a chamfer on the edge 46 of the face 48 has been found to minimize chipping thereof, both during and after their installation.

[0051] The configuration of the wall blocks 12 and 14 allows their cutting longitudinally, using for example a concrete saw, while preserving their spacers 24, and 26. With reference to FIG. 1, this allows easily creating blocks of different length, such as blocks 50 and 52, when raising a wall 10, and still maintaining the uniformity of the appearance thereof.

[0052] Turning now to FIG. 6, a wall block 54 according to a third illustrative embodiment, will now be described. Since the block 54 is similar to the block 12, only the difference therebetween will be described herein for concision purposes.

[0053] The block 54 further includes a L-shaped depression 56 along the periphery of the decorative face 16, resulting in the lateral and bottom faces 18 and 22 becoming respectively spacers 58 and 60. More specifically, the depression 56 extends along the full length of two faces 18 and 22, which are adjacent the decorative face 16.

[0054] A person skilled in the art will now appreciate that, since the depth of the depression 56 does not go all through the depth of the wall block 54, no dirt can come through from the side of the wall opposite decorative side 16.

[0055] The block 54 can be used in place of the block 12, whereby abutting side-by-side and piling on top of each other such block 54 (or block 14) yields the same lateral and longitudinal decorative joints 30 and 32,

[0056] It is to be noted that many modifications could be made to the blocks 12 and 14 or a wall 10 constructed therewith described hereinabove and illustrated in the appended drawings. For example: [0057] while the wall blocks 12, 14, and 56 are shown having generally the same dimension, similar rectangular blocks that have different sizes or proportions can also be provided, which could be used to add aesthetic variability when raising a wall; [0058] while the wall blocks 12, 14 and 54 are shown including spacers that allows their manufacturing using a process where they can be stripped out of a mold plate or cavity, a wall block provided with one or two spacers according to another illustrative embodiment (not shown) can have other configurations or be manufactured using another process than described herein; [0059] grout can be added in the decorative joints 30 and 32.

[0060] Although wall blocks and a wall therewith have been described hereinabove by way of illustrated embodiments thereof, they can be modified. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that the scope of the claims should not be limited by the thereby but should be given the broadest interpretation consistent with the description as a whole.
