Definitions
- This invention relates to a masonry block for stacking on other like-shaped blocks in a staggered, interlocking and offset manner to form a gravity-type retaining wall that is particularly suited for integrating into a variety of landscape settings.
- a variety of masonry block designs have been developed for building gravity-type retaining walls that depend on the weight of the blocks for their stability.
- Versatile block designs should take several factors into consideration. For walls three feet in height or less, the blocks should form a wall structure that can withstand the pressure of the earth behind the wall.
- the footprint of the block should be large enough to accommodate soils with relatively low bearing pressures so that the wall will not tilt or sink during use.
- the setback and height of the block should be such that the combined pressure of the earth and the weight of the wall fall within the footprint of the lowest course of blocks.
- the block design should also take into account the shape of the blocks, as well as the strength, density and durability of the material forming the block.
- Retaining wall block designs require a mechanism for securing the blocks together to produce a stable wall structure. While the friction between the relatively rough surfaces of stacked blocks can help keep the wall together, this friction is not sufficient in many retaining wall applications.
- some blocks are designed to be mortared or otherwise adhered together to produce a rigid wall structure. Unfortunately, such retaining walls are prone to cracking due to settling, frost, water buildup behind the wall and earthquakes, as well as the normal use of the wall by people and animals that walk, stand, lean or sit on the wall.
- retaining wall block designs incorporate fasteners such as rods, pins or keys to hold and clamp the blocks together. Examples of such block designs are shown in U.S. Pat. No. 4,914,876 to Forsberg, U.S. Pat. No. 3,390,502 to Carroll, and U.S. Pat. No. 4,909,010 to Gravier, the disclosures of which are incorporated by reference herein.
- a significant problem with these block designs is the expense of the extra components and increased installation costs. These designs can also suffer from unsightly cracks that tend to form in these types of walls.
- Interlocking wall block designs have been developed to overcome the problems associated with the blocks that form rigid retaining wall structures.
- Interlocking block designs typically have one or more integral projections extending from the upper or lower surface of the block. When stacked, the projection of one block abuts against a surface of another block to help hold the blocks together.
- the projections also provide a mechanism for offsetting stacked blocks. This offset or setback helps produce a more stable retaining wall that leans into the earth or hill behind the wall to resist the pressure exerted by the earth or hill on the wall.
- Individual blocks do not need to be rigidly secured by mortar, adhesive, rods, pins or keys, so that the wall is free to flex and accommodate movements in the wall caused by settling, frost, water buildup, earthquakes and normal use.
- the integral projection is located along the rear or front edge of the block.
- the setback projection is frequently only a half-inch thick when the blocks are sized for easy handling.
- these relatively thin and weak projections are located where they are easily damaged if dropped, improperly stacked or otherwise mishandled.
- rear projections are in direct contact with the wetness and acidity of the earth during use, which can cause the projection to deteriorate, weaken and fail over time.
- Front projections extend upwardly and can collect water between them and the upper course of blocks, which can freeze and crack the projection.
- a further problem with conventional interlocking masonry wall blocks is that the integral projections are relatively short in height to reduce the possibility of chipping and cracking. Although the short projections may be less likely to crack, they do not provide a sufficiently tall abutment to easily and consistently align the block over a lower course of blocks.
- workers have a tendency to leave a gap between the projection and the lower course of blocks or allow the projection to ride-up onto the upper surface of the lower block.
- These misalignments are not easily detected given the thinness of the projection and its relatively small height. This is especially so for blocks with rear projections that extend down from the lower surface of the block, because the workers are not able to easily see that the blocks are properly aligned. Misalignments can be even more difficult to notice in construction settings where dirt, gravel and other debris are present, and may compact against the setback projection or get on the upper or lower surfaces of the blocks.
- a still further problem with conventional interlocking masonry wall blocks is that they have limited ability to produce serpentine walls with straight, concave and convex portions.
- the integral projections are sized and shaped to fit into grooves of lower blocks so that the stacked blocks must be oriented a particular way. If a curve is possible, the radius of the curve is constant, so that a true serpentine wall with curves that gradually increase or decrease in radius are not possible.
- a still further problem with conventional interlocking masonry wall blocks is that the integral projections do not ensure an even amount of setback for straight and curved portions of the wall.
- a block with a flange along its front or rear edge produces a wall with discontinuities in the amount of setback between adjacent block as shown in FIG. 14 .
- the pitch of the wall is also greater in both the concave and convex curved portions of the wall than in the straight portions as shown in FIGS. 14 and 16 . This increasing setback and pitch occurs even though a retaining wall may need to be stronger and require more setback in straight portions of the wall than in curved portions.
- a still further problem with conventional interlocking masonry wall blocks is that the blocks require a fixed amount of lateral offset to the right or left of the lower blocks on which they rest. Yet, obstructions at the location where the wall is to be built or the addition of drain pipes in the wall do not always permit each block to be offset a constant amount throughout the entire wall. A block in one course may need to be laterally offset two or three inches to the right or left from the blocks beneath it, and another block in the same or a different course may need to be laterally offset four or five inches from the blocks beneath it. Yet, many interlocking block designs do not allow sufficient flexibility to offset the blocks as needed to accommodate various obstacles or drain pipes. This inflexibility can complicate construction or renders the block unusable for some retaining wall applications.
- a still further problem with conventional interlocking masonry wall blocks is that the integral projection does not provide sufficient resistance to lateral side-to-side movement of the block. Side-to-side movement is only resisted by adjacent blocks in the same course or tier. The side walls of these adjacent blocks abut each other to prevent, side-to-side movement. However, should one block in a given course shift or move out of abutting alignment with one of its adjacent blocks, then each of the blocks in that row would be susceptible to shifting as well. Moreover, the blocks that form an end of the wall are not restrained from lateral movement away from its sole adjacent block and could be knocked off the wall altogether.
- a still further problem with conventional interlocking masonry wall blocks is that several different block shapes must be combined to form the straight and curved sections of a serpentine wall.
- the need for multiple block designs result in increased manufacturing, inventory, shipping and construction costs.
- the multiple block designs also result in more complicated serpentine wall designs that are not easily integrated to the shape of a specific and unique landscape setting.
- a still further problem with conventional interlocking masonry wall blocks is that they are heavy and difficult to handle.
- the blocks are typically solid throughout.
- the openings tend to be small and do not significantly reduce the weight of the block.
- the excessive weight is compounded by the fact that the block must be tall enough to provide a setback projection or flange that is sufficiently thick to withstand cracking and chipping during transport, construction and use.
- the present invention is intended to solve these and other problems.
- the present invention relates to an interlocking masonry wall block having two spaced lugs or projections and a cooperating recess or channel that enable like-shaped blocks to be stacked in a staggered relation to form straight and serpentine walls that are particularly suited for landscaping applications.
- the lugs are located proximal the sides of the block and extend from an upper surface of the block.
- the channel is formed in a lower surface of the block.
- the lugs are located at the rear corners of the block and extend below the lower surface of the block.
- the recess is formed in the rear end of the block between the lugs.
- Like-shaped blocks are stacked in a staggered relation so that each block is stacked atop two immediately lower blocks.
- the lugs and their cooperating channel or recess define a setback dimension.
- One advantage of the present interlocking masonry wall block is that the thickness of the integral projections is not related to the desired amount of setback for each course of blocks.
- a retaining wall application requiring a half-inch setback per course can have projections that are one or two inches thick. These thicker projections are more structurally sound and not prone to chipping and cracking.
- the block can be relatively short in height to produce a block that is light weight and easy to handle.
- Another advantage of the present interlocking masonry wall block is that the block can be kept relatively short so that it can be more easily integrated into gradually sloping terrain.
- the smaller height allows more frequent steps to be incorporated into a particular wall design so the blocks do not rise up above ground level a great deal. This produces a more aesthetically pleasing wall that fits and blends into the natural terrain.
- the blocks also make more efficient use of material.
- a further advantage of the present interlocking masonry wall block is that the integral projections are robustly designed or located away from the front and rear edges of the block.
- the rear lugs are robustly and smoothly designed to withstand normal abuse during shipping and construction of a wall.
- the projections located intermediate the front and rear ends of the block are less likely to be damaged if the block is dropped or bumped during transport.
- These intermediate projections are also protected by the lower blocks during use so that they are not exposed to the earth and air. This keeps the projections dry and away from the acidity of the earth, which improves the life expectancy of the block and retaining wall formed by the blocks.
- a still further advantage of the present interlocking masonry wall block is that the integral projections are relatively thick and relatively tall.
- the projections can be relatively thick or long because they are not dependent on the desired setback. This increased thickness enables the projections to have an increased height without compromising their structural strength.
- the projections provide a sufficiently tall abutment to easily and consistently align the block over the lower course of blocks. This reduces the amount of misaligned blocks, and improves the strength and aesthetic uniformity of the retaining wall.
- a still further advantage of the present interlocking masonry wall block is that they produce serpentine walls with varying convex and concave shaped portions.
- the size and shape of the open cores allow the smaller, spaced projections to fit into the open cores of the blocks of the lower course.
- Adjacent blocks can be oriented to form a continuous wall with curves and straight portions that gradually increase or decrease in radius.
- a still further advantage of the present interlocking masonry wall block is that the integral projections produce a relatively uniform amount of setback for straight and curved portions of the wall. Even though the setback increases slightly in concave curved portions of the wall and decreases slightly in convex portions of the wall, this change in setback occurs evenly and gradually as the radius of the curve increases. Discontinuities between adjacent blocks are avoided.
- the pitch of the wall is relatively constant for straight and curved portions of the wall. The wall leans back a slightly increased amount in concave portion and less in convex portions so that a relatively constant pitch is achieved throughout the entire serpentine wall. This uniform setback and relatively constant pitch enables more courses of blocks to be used in many serpentine walls, and helps produce a more stable serpentine wall where the combined weight of the wall and earth pressure remain within the footprint of the block.
- a still further advantage of the present interlocking masonry wall block is that the integral projections allow the blocks forming one course to have a varying amount of lateral offset with relation to the course of blocks upon which they are stacked.
- the retaining wall can more easily avoid obstructions, such as a sump pump discharge pipe.
- the block can also be arranged to allow drain pipes to pass through the middle of the wall. This flexibility also allows one course of blocks to be laterally offset to accommodate the ledge or sill of a building.
- the present block facilitates the construction process and the ability to use the block in a wide variety of locations.
- a still further advantage of the present interlocking masonry wall block is that the integral projections provide additional resistance to lateral side-to-side movement of the block.
- the blocks can easily be stacked so that the outer wall of one of the lugs engages the inside wall of one of the lugs of a block upon which it lays. Accordingly, side-to-side movement is resisted not only by the adjacent blocks in the same course or tier, but by the blocks above and below it as well. Should one block in a given course shift or move out of abutting alignment with one of its adjacent blocks, then the remaining blocks in that row would still be held in place by the blocks above or below it.
- the projections are particularly helpful in holding the end blocks of the wall in place where the block would otherwise be free to slide laterally and out of place, or off the wall altogether.
- a still further advantage of the present interlocking masonry wall block is that an entire serpentine wall can be built from a plurality of like-shaped blocks.
- the need for only a single block design results in reduced manufacturing, inventory, shipping and construction costs.
- the single block design also makes it easier to design a serpentine wall that is integrated to the shape of a specific and unique landscape setting.
- a still further advantage of the present interlocking masonry wall block is its reduced weight.
- the open core and hand hold designs reduce the weight of the block so that they are easier to handle during manufacture, shipping and construction.
- the open core and hand hold designs also reduces material costs, which can be passed on to the consumer.

- This invention relates to a masonry block for stacking on other like-shaped blocks in a staggered, interlocking and offset manner to form a gravity-type retaining wall that is particularly suited for integrating into a variety of landscape settings.
- A variety of masonry block designs have been developed for building gravity-type retaining walls that depend on the weight of the blocks for their stability. Versatile block designs should take several factors into consideration. For walls three feet in height or less, the blocks should form a wall structure that can withstand the pressure of the earth behind the wall. The footprint of the block should be large enough to accommodate soils with relatively low bearing pressures so that the wall will not tilt or sink during use. The setback and height of the block should be such that the combined pressure of the earth and the weight of the wall fall within the footprint of the lowest course of blocks. The block design should also take into account the shape of the blocks, as well as the strength, density and durability of the material forming the block.
- Retaining wall block designs require a mechanism for securing the blocks together to produce a stable wall structure. While the friction between the relatively rough surfaces of stacked blocks can help keep the wall together, this friction is not sufficient in many retaining wall applications. To increase stability, some blocks are designed to be mortared or otherwise adhered together to produce a rigid wall structure. Unfortunately, such retaining walls are prone to cracking due to settling, frost, water buildup behind the wall and earthquakes, as well as the normal use of the wall by people and animals that walk, stand, lean or sit on the wall.
- Other retaining wall block designs incorporate fasteners such as rods, pins or keys to hold and clamp the blocks together. Examples of such block designs are shown in U.S. Pat. No. 4,914,876 to Forsberg, U.S. Pat. No. 3,390,502 to Carroll, and U.S. Pat. No. 4,909,010 to Gravier, the disclosures of which are incorporated by reference herein. A significant problem with these block designs is the expense of the extra components and increased installation costs. These designs can also suffer from unsightly cracks that tend to form in these types of walls.
- Interlocking wall block designs have been developed to overcome the problems associated with the blocks that form rigid retaining wall structures. Interlocking block designs typically have one or more integral projections extending from the upper or lower surface of the block. When stacked, the projection of one block abuts against a surface of another block to help hold the blocks together. The projections also provide a mechanism for offsetting stacked blocks. This offset or setback helps produce a more stable retaining wall that leans into the earth or hill behind the wall to resist the pressure exerted by the earth or hill on the wall. Individual blocks do not need to be rigidly secured by mortar, adhesive, rods, pins or keys, so that the wall is free to flex and accommodate movements in the wall caused by settling, frost, water buildup, earthquakes and normal use. Blocks for retaining walls of this type are described in U.S. Pat. No. 5,827,015 to Woolford, U.S. Pat. No. 2,313,363 to Schmitt, and U.S. Pat. No. 4,565,043 to Mazzarese, the disclosures of which are incorporated by reference herein.
- One problem with conventional interlocking masonry wall blocks is that the thickness of the integral projection is directly related to the amount of setback desired for each course of blocks. A retaining wall application requiring a half-inch setback per course requires blocks with half-inch thick projections. Yet, thin projections are structurally weak and prone to chipping and cracking. While the height of the block can be increased to increase the thickness of its setback, this results in a heavier block that is more difficult to handle. In addition, tall blocks also do not lend themselves to landscaping gradually sloping terrain. Large portions of the block stick out above ground level before a step down at the end of a row or course of blocks can occur. This produces an unsightly wall and results in a waste of material.
- Another problem with conventional interlocking masonry wall blocks is that the integral projection is located along the rear or front edge of the block. As noted above, the setback projection is frequently only a half-inch thick when the blocks are sized for easy handling. Yet, these relatively thin and weak projections are located where they are easily damaged if dropped, improperly stacked or otherwise mishandled. In addition, rear projections are in direct contact with the wetness and acidity of the earth during use, which can cause the projection to deteriorate, weaken and fail over time. Front projections extend upwardly and can collect water between them and the upper course of blocks, which can freeze and crack the projection.
- A further problem with conventional interlocking masonry wall blocks is that the integral projections are relatively short in height to reduce the possibility of chipping and cracking. Although the short projections may be less likely to crack, they do not provide a sufficiently tall abutment to easily and consistently align the block over a lower course of blocks. During construction of a wall, workers have a tendency to leave a gap between the projection and the lower course of blocks or allow the projection to ride-up onto the upper surface of the lower block. These misalignments are not easily detected given the thinness of the projection and its relatively small height. This is especially so for blocks with rear projections that extend down from the lower surface of the block, because the workers are not able to easily see that the blocks are properly aligned. Misalignments can be even more difficult to notice in construction settings where dirt, gravel and other debris are present, and may compact against the setback projection or get on the upper or lower surfaces of the blocks.
- A still further problem with conventional interlocking masonry wall blocks is that they have limited ability to produce serpentine walls with straight, concave and convex portions. The integral projections are sized and shaped to fit into grooves of lower blocks so that the stacked blocks must be oriented a particular way. If a curve is possible, the radius of the curve is constant, so that a true serpentine wall with curves that gradually increase or decrease in radius are not possible. These limitations of conventional block designs prevent the wall from being integrated into the natural contours of the landscape and thus impede the aesthetic value of the wall.
- A still further problem with conventional interlocking masonry wall blocks is that the integral projections do not ensure an even amount of setback for straight and curved portions of the wall. For example, a block with a flange along its front or rear edge produces a wall with discontinuities in the amount of setback between adjacent block as shown in
FIG. 14 . In addition, the pitch of the wall is also greater in both the concave and convex curved portions of the wall than in the straight portions as shown inFIGS. 14 and 16 . This increasing setback and pitch occurs even though a retaining wall may need to be stronger and require more setback in straight portions of the wall than in curved portions. - A still further problem with conventional interlocking masonry wall blocks is that the blocks require a fixed amount of lateral offset to the right or left of the lower blocks on which they rest. Yet, obstructions at the location where the wall is to be built or the addition of drain pipes in the wall do not always permit each block to be offset a constant amount throughout the entire wall. A block in one course may need to be laterally offset two or three inches to the right or left from the blocks beneath it, and another block in the same or a different course may need to be laterally offset four or five inches from the blocks beneath it. Yet, many interlocking block designs do not allow sufficient flexibility to offset the blocks as needed to accommodate various obstacles or drain pipes. This inflexibility can complicate construction or renders the block unusable for some retaining wall applications.
- A still further problem with conventional interlocking masonry wall blocks is that the integral projection does not provide sufficient resistance to lateral side-to-side movement of the block. Side-to-side movement is only resisted by adjacent blocks in the same course or tier. The side walls of these adjacent blocks abut each other to prevent, side-to-side movement. However, should one block in a given course shift or move out of abutting alignment with one of its adjacent blocks, then each of the blocks in that row would be susceptible to shifting as well. Moreover, the blocks that form an end of the wall are not restrained from lateral movement away from its sole adjacent block and could be knocked off the wall altogether.
- A still further problem with conventional interlocking masonry wall blocks is that several different block shapes must be combined to form the straight and curved sections of a serpentine wall. The need for multiple block designs result in increased manufacturing, inventory, shipping and construction costs. The multiple block designs also result in more complicated serpentine wall designs that are not easily integrated to the shape of a specific and unique landscape setting.
- A still further problem with conventional interlocking masonry wall blocks is that they are heavy and difficult to handle. The blocks are typically solid throughout. The openings tend to be small and do not significantly reduce the weight of the block. The excessive weight is compounded by the fact that the block must be tall enough to provide a setback projection or flange that is sufficiently thick to withstand cracking and chipping during transport, construction and use.
- The present invention is intended to solve these and other problems.
- The present invention relates to an interlocking masonry wall block having two spaced lugs or projections and a cooperating recess or channel that enable like-shaped blocks to be stacked in a staggered relation to form straight and serpentine walls that are particularly suited for landscaping applications. In one embodiment, the lugs are located proximal the sides of the block and extend from an upper surface of the block. The channel is formed in a lower surface of the block. In another embodiment, the lugs are located at the rear corners of the block and extend below the lower surface of the block. The recess is formed in the rear end of the block between the lugs. Like-shaped blocks are stacked in a staggered relation so that each block is stacked atop two immediately lower blocks. In each embodiment, the lugs and their cooperating channel or recess define a setback dimension.
- One advantage of the present interlocking masonry wall block is that the thickness of the integral projections is not related to the desired amount of setback for each course of blocks. A retaining wall application requiring a half-inch setback per course can have projections that are one or two inches thick. These thicker projections are more structurally sound and not prone to chipping and cracking. The block can be relatively short in height to produce a block that is light weight and easy to handle.
- Another advantage of the present interlocking masonry wall block is that the block can be kept relatively short so that it can be more easily integrated into gradually sloping terrain. The smaller height allows more frequent steps to be incorporated into a particular wall design so the blocks do not rise up above ground level a great deal. This produces a more aesthetically pleasing wall that fits and blends into the natural terrain. The blocks also make more efficient use of material.
- A further advantage of the present interlocking masonry wall block is that the integral projections are robustly designed or located away from the front and rear edges of the block. The rear lugs are robustly and smoothly designed to withstand normal abuse during shipping and construction of a wall. The projections located intermediate the front and rear ends of the block are less likely to be damaged if the block is dropped or bumped during transport. These intermediate projections are also protected by the lower blocks during use so that they are not exposed to the earth and air. This keeps the projections dry and away from the acidity of the earth, which improves the life expectancy of the block and retaining wall formed by the blocks.
- A still further advantage of the present interlocking masonry wall block is that the integral projections are relatively thick and relatively tall. As stated above, the projections can be relatively thick or long because they are not dependent on the desired setback. This increased thickness enables the projections to have an increased height without compromising their structural strength. The projections provide a sufficiently tall abutment to easily and consistently align the block over the lower course of blocks. This reduces the amount of misaligned blocks, and improves the strength and aesthetic uniformity of the retaining wall.
- A still further advantage of the present interlocking masonry wall block is that they produce serpentine walls with varying convex and concave shaped portions. The size and shape of the open cores allow the smaller, spaced projections to fit into the open cores of the blocks of the lower course. Adjacent blocks can be oriented to form a continuous wall with curves and straight portions that gradually increase or decrease in radius.
- A still further advantage of the present interlocking masonry wall block is that the integral projections produce a relatively uniform amount of setback for straight and curved portions of the wall. Even though the setback increases slightly in concave curved portions of the wall and decreases slightly in convex portions of the wall, this change in setback occurs evenly and gradually as the radius of the curve increases. Discontinuities between adjacent blocks are avoided. In addition, the pitch of the wall is relatively constant for straight and curved portions of the wall. The wall leans back a slightly increased amount in concave portion and less in convex portions so that a relatively constant pitch is achieved throughout the entire serpentine wall. This uniform setback and relatively constant pitch enables more courses of blocks to be used in many serpentine walls, and helps produce a more stable serpentine wall where the combined weight of the wall and earth pressure remain within the footprint of the block.
- A still further advantage of the present interlocking masonry wall block is that the integral projections allow the blocks forming one course to have a varying amount of lateral offset with relation to the course of blocks upon which they are stacked. The retaining wall can more easily avoid obstructions, such as a sump pump discharge pipe. The block can also be arranged to allow drain pipes to pass through the middle of the wall. This flexibility also allows one course of blocks to be laterally offset to accommodate the ledge or sill of a building. Thus, the present block facilitates the construction process and the ability to use the block in a wide variety of locations.
- A still further advantage of the present interlocking masonry wall block is that the integral projections provide additional resistance to lateral side-to-side movement of the block. The blocks can easily be stacked so that the outer wall of one of the lugs engages the inside wall of one of the lugs of a block upon which it lays. Accordingly, side-to-side movement is resisted not only by the adjacent blocks in the same course or tier, but by the blocks above and below it as well. Should one block in a given course shift or move out of abutting alignment with one of its adjacent blocks, then the remaining blocks in that row would still be held in place by the blocks above or below it. The projections are particularly helpful in holding the end blocks of the wall in place where the block would otherwise be free to slide laterally and out of place, or off the wall altogether.
- A still further advantage of the present interlocking masonry wall block is that an entire serpentine wall can be built from a plurality of like-shaped blocks. The need for only a single block design results in reduced manufacturing, inventory, shipping and construction costs. The single block design also makes it easier to design a serpentine wall that is integrated to the shape of a specific and unique landscape setting.
- A still further advantage of the present interlocking masonry wall block is its reduced weight. The open core and hand hold designs reduce the weight of the block so that they are easier to handle during manufacture, shipping and construction. The open core and hand hold designs also reduces material costs, which can be passed on to the consumer.
- Other aspects and advantages of the invention will become apparent upon making reference to the specification, claims and drawings.

The house is constructed into ahill 20 that levels off to aparticular ground level 22 in the backyard of the house. Thehill 20 and itsterrain 30 andnatural plant life 24 form a unique landscape setting 32 around thehouse 10. -
FIGS. 2-16 pertain to a first interlocking masonry block design that is generally referred to byreference number 40. As with each of the block designs discussed below, theblock 40 can be used for constructing serpentine retaining walls with straight and curved portions, such as thelandscape retaining wall 140 shown inFIG. 2 . Theserpentine wall 140 is easily integrated into a variety oflandscape settings 32. The like-shapedblocks 40 have a setback, as discussed below. A degree of setback is maintained throughout the entireserpentine wall 140. As discussed below, the setback impacts the degree the wall is pitched or leans into thehill 20. As shown inFIG. 3 a, 3 b and 3 c, the amount of pitch (P) in thewall 140 is somewhat less in convex curved portions of the wall and somewhat greater in concave portions of the wall relative to the pitch in straight portions of the wall. - An
individual block 40 in accordance with the first embodiment of the present invention is shown inFIGS. 4-9 . Theblock 40 has amain body 42 with upper 44 and lower 45 surfaces. The upper 44 and lower 45 surfaces are generally parallel to each other. When laid in place on a horizontal supporting surface, the upper 44 and lower 45 surfaces are horizontal as well. Themain body 42 includes afront wall 51, arear wall 52, and opposedside walls continuous surfaces outer surface 62 of thefront wall 51 is roughened to give it a natural cut or chipped stone finish. A conventional masonry material for landscape retaining wall blocks is used to form theblock 40. Asingle block 40 weighs about twelve pounds. - The
block 40 has a generally trapezoidal shape as best shown inFIGS. 7 and 8 . The inside 61 and outside 62 surfaces of the front 51 and rear 52 walls are parallel, and perpendicular to the upper 44 and lower 45 surfaces. The inside 61 and outside 62 surfaces of theside walls block 40 has a height of about four (4) inches and a depth of about eight (8) inches. The width of the block at itsfront wall 51 is roughly twelve (12) inches from theouter surface 62 of eachside wall rear wall 52 is roughly ten (10) inches from the outer surface of eachside wall side wall back wall 52. Theoutside surface 62 of thefront wall 51 has beveled ends 65. The surface of theseends 65 angle back toward the rear of the block. Theoutside surface 62 of the angled ends 65 meet the outside surface of theside walls outside surface 62 of therear wall 52 meets the outside surface of theside walls - The
block 40 has an open core or interior 80 that extends completely through the block from itsupper surface 44 to itslower surface 45. Theopen core 80 is defined by the inside surfaces 61 of the front, rear and side walls 51-54. Theopen core 80 has a generally trapezoidal shape that is smaller in size and similar to the trapezoidal shape formed by theouter surface 62 or perimeter of theblock 40. Theopen core 80 has a width at its front of about seven and a half (7½) inches, and a width at its rear of about six and a half (6½) inches. Theopen core 80 is about four (4) inches deep taken along a line perpendicular to the inside surfaces 61 of the front andrear walls corners 82 of theopen core 80 are rounded to a radius of roughly three-quarters (¾) of an inch. One of ordinary skill in the art should readily appreciate that the volume of the core can vary, but is preferably maximized to decrease the weight and material cost of the block without impairing the strength, integrity and manufacturability of the block. Similarly, the actual shape and dimensions of the core 80 can vary, provided the core maintains its ability to receive the lug-shaped projections of anotherblock 40, as discussed below. Theopen core 80 should not contain any obstruction that would interfere with the desired ability to receive these lugs. - Two integral lug-shaped
projections lower surface 45 of theblock 40. Theprojections front 111, rear 112 andopposed side lower surface 45 of the block and parallel to the inside and outside surfaces 61 and 62 of the walls 51-54, respectively. Eachlug bottom surface 115 that is generally parallel to thelower surface 45 of theblock 40. Eachlug side 113 toside 114, and a length or thickness of about one and a half (1½) inches fromfront 111 to rear 112. Eachlug vertical edges 117 are rounded to a radius of about seven-sixteenths ({fraction (7/16)}) of an inch. One of ordinary skill in the art should readily appreciate that the size and shape of thelugs - Each
projection respective side wall projection portion 118 positioned forward or in front of theinside surface 62 of thefront wall 51. Thisportion 118 provides an amount ofsetback 120 for theblock 40. The perpendicular distance between thefront surface 111 of eachprojection inside surface 62 offront wall 51 is thesetback dimension 120. In this embodiment, thesetback dimension 120 is shown to be about one-quarter (¼) of an inch. Thesetback 120 is the same for bothprojections setback dimension 120 could be larger or smaller without departing from the broad aspect of this present wall block invention. Eachprojection centerline 119. Thiscenterline 119 is shown perpendicular to the inside and outside surfaces 61 and 62 of thefront wall 51, but could be parallel to the inside and outside surfaces of itsrespective side wall - The like-shaped
blocks 40 are structured to be laterally aligned in an abutting side-by-side engagement, and vertically aligned in a staggered, stacked manner so that one block rests atop two other blocks. When arranged in this manner, theblocks 40 form amulti-tiered wall 140, such as the wall shown inFIG. 2 . Thewall 140 is typically constructed one course at a time. Once alower course 141 is set in place, anupper course 142 is placed on top of it. Theblocks 40 can be arranged to formwalls 140 havingstraight wall portions 150 as inFIG. 10 , concavecurved wall portions 160 as inFIG. 11 , and convexcurved wall portions 170 as inFIG. 12 . Theconcave portions 160 have a degree of curvature that ranges from alow radius curve 161, to amedium radius curve 162, to ahigh radius curve 163. Similarly, theconvex portions 170 range from low 171, tomedium 172, to high 173 radius curves. Theblocks 40 can be arranged to gradually or rapidly increase or decrease the radius of the curvature of the concave orconvex curves wall 140 to conform to the unique landscape setting 30. - When erecting a
wall 140, a gravel orsand bed 179 is preferably formed to level theterrain 32 where thefirst course 141 ofblocks 40 is to be laid. In eachcourse adjacent blocks 40 are aligned. The front edges 67 are aligned in abutting engagement instraight wall portions 150 as shown inFIGS. 2 and 13 , low radiusconcave wall portions 161 as shown inFIGS. 11 and 15 , and all convex wall portions 170-173 as shown inFIGS. 12 and 13 . The front andrear edges side walls adjacent blocks 40 are flushly aligned in abutting engagement for a medium radiusconcave wall portions 162 as shown inFIG. 11 . High radiusconcave wall portions 163 are formed by aligning therear edges 68 ofadjacent blocks 40 as shown inFIG. 11 . Thelower surface 45 of eachblock 40 in the first orlowest course 141 is placed at the same horizontal level, which is deemed theground level 22. In thefirst course 141, theprojections sand bed 179. The upper surfaces 44 of theblocks 40 forming thelower course 141 form a generally horizontal platform upon which theupper course 142 can be stacked. Thelower surface 45 of eachblock 40 in each stacked,upper course 142 is placed on and rests on theupper surfaces 44 of the blocks in thelower course 141 upon which it is placed. - An interlocking fit is achieved between the like-shaped
blocks 40 in adjacent upper 142 and lower 141 courses. Eachblock 40 in theupper course 142 is laid in a staggered manner relative to thelower course 141 SO that the upper block is placed atop two lower blocks. Eachblock 40 in theupper course 142 is placed so that one of its lug-shapedprojections 100 ort (or?) 101 extends into and is received by theopen core 80 of one of the lower blocks. Theother projection open core 80 of an adjacent lower block. Thefront surface 111 of eachlug upper block 40 abuts theinside surface 61 of thefront wall 51 of its respective lower block. This abutting engagement between the upper andlower blocks 40 inadjacent courses upper course 142 from moving forward. This interlock enables theblocks 40 in theupper courses 142 to resist the pressure of the earth andhill 20 behind thewall 140. - A further aspect of the interlocking fit is achieved by aligning the
block 40 in theupper course 142 so that one of itsprojections rounded corner 82 or insidesurface 61 of theside wall lower course 141. When in a full right 181 or frill left 182 alignment as shown inFIG. 10 , theblocks 40 in theupper course 142 are prevented from sliding sideways or laterally relative to the blocks in thelower course 141. Theblock 40 in thelower course 141 experiences a similar resistance to movement in the opposite lateral direction. A block in a middle course may experience a resistance to both right and left movement. -
Adjacent blocks 40 in aparticular course alignment 185. Oneblock 40 can be positioned in a fullright alignment 181 and its adjacent block can be position in a fullleft alignment 182 to form a gap oropening 187 between the two blocks shown as inFIGS. 2 and 10 . The maximum amount of offset of the preferred embodiment of theblock 40 is about six (6) inches. The ability to laterally offsetadjacent blocks 40 to createopenings 187 in the otherwisesolid wall 140 enables the wall to accommodate drainage pipes, gutter down spouts, sump pump piping or other obstacles, and helps prevent excessive water building up behind the retaining wall. - As discussed above, the
projections setback 120 between the upper and lower courses ofblocks wall 140 is properly constructed, theblocks 40 in theupper course 142 are set back apredetermined amount 120 from the blocks on which they are placed. In the preferred embodiment, theouter surface 62 of thefront wall 51 of theupper block 40 is set back about one quarter (¼) inch from the outer surface of the lower blocks on which it is placed. Thesetback dimension 120 directly affects the amount or degree of pitch P in thewall 140. Thesetback 120 of eachblock 40 in theupper course 172 is substantially the same when measured along thecenterline 119 of eachprojection blocks 40 form astraight wall segment 150, the height of theblocks 40 and thesetback amount 120 determine the pitch of the wall. The amount of pitch can vary slightly in an actual construction setting due to the present of dirt or other debris, which can come between thelugs inside surface 61 of thefront wall 51 of the lower block. When theblocks 40 form acurved wall segment FIG. 13 , awall 140 having a pitch in straight wall section of Ps=1.0, should have a reduced pitch in a medium radiusconvex section 172 of about Pmr=0.7 times Ps, and a high radiusconvex section 173 of about Phr=0.4 times Ps. As shown inFIG. 15 , thewall 140 should have an increased pitch in a medium radiusconcave section 162 of about Pmr=1.4 times Ps, and a high radiusconcave section 163 of about Phr=1.8 times Ps. A more consistent pitch is believed to occur with thiswall 140 than in other conventional walls, such as the wall shown inFIGS. 14 and 16 , because the lug-shapedprojections block 40, and are located toward thefront wall 51 and inwardly from the outside surfaces 62 of theside walls - The top course of
blocks 40 in thelandscape retaining wall 140 is preferably capped bycap stones 195 to cover theopen cores 80 of theblocks 40 that form the top course or portion of a course. Thesecap stones 195 provide a finished look to the wall. Thesecap stones 195 can be glued or otherwise adhered to theupper surface 44 of theblocks 40. -
FIGS. 17-26 show a second interlocking masonry wall block design that is generally indicated byreference number 200. In the preferred embodiment, theblock 200 has amain body 205 with a generally trapezoidal shape when viewed from above. Themain body 205 with a height dimension of about six (6) inches, a depth dimension of about eight (8) inches and a width dimension of about twelve (12) inches at its widest point. However, it should be understood that these dimensions can vary without departing from the broad aspects of this inventive block design. Similarly, it should be understood that the broad aspects of the design are not limited to a block with a trapezoidal shape, but would apply to other block shapes such as a square or rectangular shaped block. While the preferred block material is a masonry product, it should be understood that other weather resistant materials such as hardened plastic could be substituted without departing from the broad aspects of the invention. - As shown in
FIGS. 17 and 19 , themain body 205 of theblock 200 has afront end 206, arear end 207 andsides front end 206 has a multi-facetedfront wall 215. Thefront wall 215 has acentral wall 220 and twoouter walls wall center wall 220 has a top 221, twoopposed sides center wall 220 is about eight (8) inches wide. The bottom half inch of thecenter wall 220 has achamfer 225. Thechamfer 225 has an angle of about 45 degree from the surface of the central wall. Eachouter wall inner side outer side inner side 232 ofouter wall 230 joins thefirst side 222 of thecenter wall 220 to form a first facet. Theinner side 242 ofouter wall 240 joins thesecond side 223 of thecentral wall 220 to form a second facet. Theouter walls rear end 207 of theblock 200. Theouter walls outer walls front end 206 of theblock 200 between the outer ends 233 and 243 of thefront wall 215 is about twelve (12) inches. Similar to thecentral wall 220, the bottom half inch of eachouter wall chamfer chamfers - The
rear end 207 of theblock 200 is shown inFIG. 23 . Therear end 207 is formed by arear wall 250 that is substantially parallel to thecenter wall portion 220 of thefront wall 215. Therear wall 250 has atop end 252,bottom end 253, and opposed sides ends 254 and 255. Therear wall 250 has a width dimension of about nine (9) inches. A V-shapedgroove 256 is formed into therear wall 250. Thisgroove 256 extends form the top 252 to thebottom 253 of thewall 250. The groove helps split the block into two symmetrical halves. Thevertical groove 256 is parallel to side ends 254 and 255 and is perpendicular to top and bottom ends 252 and 253. Therear wall 250 is symmetrical about both sides of thegroove 256. - The
first side end 208 of theblock 200 has afirst side wall 260 as shown inFIG. 18 .

recess wall 854 has a continuous linear shape from oneside 880 of the block to the other 870, particularly along itstop end 855. The continuous linear shape of therecess wall 854 allows the block to receive one of thelugs upper block 800 at any point along the recess wall between itsends recess wall 854 creates a degree of flexibility in lug alignment. This flexibility in lug alignment allows adjacent blocks of one course to pivot about their abutting pivot joints while allowing each of those blocks to abuttingly receive the lugs of two upper blocks to form a free flowing serpentine wall that fits into a natural landscape setting. - The effective thickness Lth of a circular shaped
lugs lug wall 903 other than the frontmost point 904 abuttingly engages therecess wall 854 of the lower block, the full diameter or thickness Lth of the lug is available to absorb the load placed on the lug. - Although the
block 800 has been shown and described to have a preferred geometric shape, it should be understood that certain aspects of this geometry can change without departing from the broad aspects of this embodiment. For example, the angles of theouter walls front wall 815 can vary, or the facets can be eliminated so that thefront wall 815 has a single planar surface from oneouter end 833 to the other 843. Additionally, several grooves can be formed in theblock 800 to allow smaller or larger portions of the block to be split off to form the end blocks of eachcourse -
