Abstract
A concrete block that can be placed in a wall constructed from a plurality of concrete blocks to accent the wall face. The block has a relief formed on a depressed field on the front of the block. The depressed field is preferably surrounded by a border that projects forwardly beyond the depressed field, and a portion or all of the relief projects forwardly beyond the border. One or more of the blocks of the invention can be placed as desired in the wall to break up the uniformity of the wall face and soften the plane of the wall, tie the wall in with the surrounding landscape, or to add interest to an otherwise uniform wall face.
Description
- The invention relates generally to concrete blocks. More specifically, the invention relates to concrete blocks suitable for use in landscaping applications, such as retaining walls, and other architectural applications.
- It has become common to use concrete blocks for constructing structures in a variety of applications. One example is in landscaping applications, where such blocks are used to create, for example, retaining walls, ranging from small tree ring walls and garden edging walls to comparatively large structures.
- In a retaining wall, as well as in other structures constructed from concrete blocks, the front face of each block, which often has a generally similar appearance to the front faces of the other blocks, is typically visible in use. The appearance of the resulting wall face created from such blocks can tend to have a uniformity or “sameness”. While uniformity is not undesirable in many applications, in some settings, such as a garden, the wall face may appear to some to be too harsh, imposing, or out-of-place. Therefore, in some instances, it would be desirable to break up the uniformity of the wall face.
- It is known to mold blocks within a mold, in which a mold surface imparts a decorative pattern to a corresponding surface of the block to enhance the visual appeal of the block. Examples include U.S. Pat. Nos. D20,287; D21,522; 451,799; 765,086; 985,353; and 1,166,312.
- However, there is a continuing need for a concrete block that includes at least one decorated surface, so that when the block is used in, for example, a retaining wall constructed from a plurality of concrete blocks, the decorated surface breaks up the uniformity of the wall face and softens the expansive plane created by the wall face.
- The invention relates to a concrete block that can be placed in a wall that is constructed from a plurality of concrete blocks to accent the wall face. The concrete block is preferably a retaining wall block for use in a retaining wall in landscape applications. However, the block could be used in other walls that are constructed from concrete blocks.
- One or more of the blocks of the invention can be placed as desired in the wall to break up the uniformity of the wall face and soften the plane of the wall, tie the wall in with the surrounding landscape, or to add interest to an otherwise uniform wall face. The blocks can be placed randomly in the wall, or arranged in a pattern in one or more courses of the wall.
- In the preferred embodiment, the block has a front face composed of one or more decorative features. The decorative feature is preferably integrally formed on the block during formation of the block. Thus, the decorative feature will have the appearance of having been carved in the face of the block.
- Examples of decorative features that could be used on the inventive block includes leaves, flowers, trees, various insects and animals including butterflies and dragonflies, human faces, scenes of nature, letters, and numbers. Numerous other decorative features could be used within the scope of the invention.
- In the preferred embodiment, the decorative feature comprises a relief formed on a depressed field on the front of the block. The depressed field is preferably surrounded by a border that projects forwardly beyond the depressed field, and a portion or all of the relief projects forwardly beyond the border. The border serves as a frame for the decorative relief. In addition, the border helps to protect the relief from being damaged, for example during handling and transport of the block. The relief could also be designed such that no portion thereof projects forwardly beyond the border.
- The relief will appear to have been carved out of an undecorated block, and the border will appear as though it is a border of remaining stone. However, it is contemplated that the relief could overlap one or more portions of the border, thereby obscuring the border in that location. Alternatively, it is contemplated that where the relief is expected to overlap the border, the border could be removed in those areas.
- In one embodiment according to the invention, the block comprises at least one locator protrusion which interacts with one or more adjacent blocks when laid up in a wall to aid in positioning and retaining the block relative to the adjacent blocks. The locator protrusion preferably comprises a flange that is integrally formed with the block adjacent the rear of the block to provide shear resistance and set-back with respect to blocks in the next lower course of blocks in the wall.
- In another embodiment according to the invention, the block is configured as an insert to be inserted into an already existing wall. In this case, the block insert preferably has a depth between the front and rear thereof that is less than the depth of the other blocks in the wall. This permits the block insert to be inserted into an opening provided in the wall face, without requiring dismantling of the wall. The block insert can be secured in place using an adhesive.
- These and various other advantages and features of novelty which characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages and objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying description, in which there is described a preferred embodiment of the invention.

- A
concrete block 10 according to the present invention is illustrated in FIGS. 1-5. Theblock 10 is illustrated as being a retaining wall block for use in a retaining wall. It is to be realized, however, that the concepts disclosed herein are applicable to other types of concrete blocks. - The
block 10 comprises a block body having afront 12, aback 14, atop surface 16, abottom surface 18, afirst side 20, and an opposedsecond side 22. Theblock 10 is formed from a cured, dry cast, no slump masonry concrete. Dry cast, no slump masonry concrete is well known in the art of retaining wall blocks. - The
front 12 of theblock 10, as illustrated in FIGS. 1-5, is provided with a pre-determined three-dimensional relief orpattern 24 on adepressed field 26, which is surrounded at least partially by aborder 28. In the preferred embodiment, theborder 28 includes atop portion 30, abottom portion 32, and first andsecond side portions border 28 entirely surrounds thedepressed field 26 and therelief 24. However, theborder 28 could surround only portions of thefield 26 andrelief 24 if desired. Moreover, therelief 24 is illustrated as intersecting theborder 28 at several locations, for example locations A, B and C. At several locations, for example locations A and B, therelief 24 overlaps theborder 28. However, therelief 24 could be entirely within theborder 28 if desired. - In the illustrated embodiment, the top and
bottom portions border 28 intersect theside portions inner corner junctions 38 a, b, c, d that are radiused. In addition, thetop portion 30 of theborder 28 is adjacent and intersects thetop surface 16, thebottom portion 32 is adjacent and intersects thebottom surface 18, theside portion 34 is adjacent and intersects theside 20, and theside portion 36 is adjacent and intersects theside 22. Other configurations of theborder 28 are possible within the scope of the invention. For example, one or more of theborder portions - With reference to FIG. 2, the
depressed field 26 includessurface portions 40 that are not provided with therelief 24. It is preferred that thesesurface portions 40 be generally smooth and without ornamentation, which helps make therelief 24 “stand-out” from the surrounding block structure. However, it is contemplated that thesurface portions 40 could be textured. - As shown in FIGS.1-3, the
border 28 projects forwardly beyond thesurface portions 40 of thedepressed field 26. In addition, it is preferred that at least a portion of therelief 24 projects forwardly beyond the border and, at certain locations as discussed above, therelief 24 overlaps portions of the border, as best seen in FIGS. 1 and 3-5. With this construction, theborder 28 helps to frame therelief 24, while therelief 24 on the smooth,depressed field 26 helps the relief “stand-out” and make it readily discernible. If desired, theentire relief 24 could project forwardly beyond theborder 28. Moreover, thedepressed field 26 could extend into the block from theborder 28 toward the back 14 a greater or lesser extent than shown in FIGS. 1-5, depending upon the look one seeks to achieve. - In the illustrated embodiment, the front12 is curved outwardly into a convex shape between the
sides sides - The
relief 24,depressed field 26 andborder 28 are preferably imparted to the front 12 during molding of theblock 10 by a mold surface having a pattern that is the mirror image of therelief 24,depressed field 26 andborder 28 to be formed. The use of a mold surface to impart a pattern to a block surface is well known in the art of retaining wall blocks. An example of a process that could be used to produce therelief 24,depressed field 26 andborder 28 is disclosed in application Ser. No. 10/038,639, filed on Jan. 4, 2002, and entitled MASONRY BLOCK AND METHOD OF MAKING SAME. - The
relief 24,depressed field 26, andborder 28 that are imparted to the front 12 can vary depending upon the desired appearance of the block front. The particular relief that is used will be selected based on what is thought to be visually pleasing to users of the blocks. By way of example, therelief 24 illustrated in FIGS. 1-5 simulates oak leaves and acorns. Other examples of patterns include leaves, flowers, trees, various insects and animals including butterflies and dragonflies, human faces, scenes of nature, letters, numbers, and combinations thereof. Endless possibilities are available. By providing a plurality of mold surfaces with a variety of different patterns, the resulting relief on blocks can be varied by changing mold surfaces. - The back14, top and
bottom surfaces sides block 10 can have numerous configurations. In theblock 10 illustrated in FIGS. 1-5, the back 14, top andbottom surfaces sides back 14 of theblock 10 is generally planar between thesides bottom surfaces - The
top surface 16 has at least a contact portion that is generally horizontal and generally planar which, in use, is contacted by a bottom surface of at least one block in an upper course of blocks. In the illustrated embodiment, thetop surface 16 is generally horizontal and generally planar over its entire extent, and free of cores intersecting theupper face 16. When theblock 10 is disposed in a wall, thetop surface 16 is in a generally parallel relationship to the top surfaces of the other blocks in the wall. - The
bottom surface 18 of theblock 10 is formed so as to be suitable for engaging the top surface of a block(s) in the course below to maintain the generally parallel relationship between the top surfaces of the blocks when the blocks are stacked into courses. Thebottom surface 18 has at least a contact portion that is generally horizontal and generally planar that is configured so that, in use, the contact portion rests upon at least a portion of a top surface of a block disposed in a course below the block. - In the illustrated embodiment, the
bottom surface 18 includes a pair ofrecesses top surface 16. However, other bottom surfaces can be used, including a bottom surface that is entirely horizontal and planar, or that includes one or more concave portions over portions of thebottom surface 18. - The
sides block 10 are generally vertical and join the top andbottom surfaces side side sides sides sides - Alternatively, the
block 10 can be provided with only one converging side or side portion, with the other side being substantially perpendicular to the front and back 12, 14. A block with at least one converging side permits serpentine retaining walls to be constructed. - The
block 10 can include one or more locator protrusions integrally formed on the top orbottom surface flange 44 that extends below thebottom surface 18 of the block adjacent to the back 14, as seen in FIGS. 1-3 and 5. Theflange 44 includes a rear surface that is continuous with theback 14 of the block. Theflange 44 is designed to abut against the rear face of a block(s) in the course below theblock 10 to provide a predetermined set-back from the course below and to provide course-to-course shear strength. - A second embodiment of a
block 100 according to the invention is illustrated in FIG. 6. Theblock 100 is designed as an insert that can be inserted into a suitable space provided in a pre-existing wall, without requiring dismantling of the wall. Theblock 100 can be secured within the wall using a suitable adhesive. - The
block 100 comprises a block body having a front 102, a back 104, atop surface 106, abottom surface 108, afirst side 110, and an opposedsecond side 112. Theblock 100, like theblock 10, is formed from a cured, dry cast, no slump concrete. - Moreover, like the
block 10, thefront 102 of theblock 100 is provided with a pre-determined three-dimensional relief orpattern 114 on adepressed field 116, which is surrounded at least partially by aborder 118. Thefront 102 of theblock 100 is identical to thefront 12 of theblock 10 and is, therefore, not further described. - In this embodiment, the depth X of the
block 100 along a straight line between the forwardmost point on theborder 118 and the rear 104 is less than the depth of most of the other blocks in the wall into which it is to be inserted. Theblock 100 preferably has a height and a width that is approximately equal to the height and width of the pre-existing blocks in the wall. This permits theblock 100 to be inserted into the wall in an opening formed in the wall. Such an opening can be formed, for example, by unstacking a portion of an existing wall, inserting one ormore blocks 100 where desired, and then restacking the wall. An opening could also be formed by, for example, removing the front portion of one of the pre-existing blocks in a wall using, for example, a hammer and chisel. - FIG. 7 is a view of a portion of a retaining
wall 50 that depicts blocks according to the invention placed in the wall. The blocks can either be a full size block like theblock 10, or a block insert like theblock 100, or a combination of both blocks. The blocks depicted in FIG. 7 are illustrated with an alternative embodiment of a decorative relief that can be provided on the front of the block. - The above specification and examples provide a complete description of the manufacture and use of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
