SPECIFICATION
Fi e l tl of the Tr ver t; or This invention relates to building blocks, and more specifically to substitutes for masonry blocks used in forming edging for flower beds, lawns and the like.
R~ çrro~n~ of the Tnve~ti or In the landscaping arts, it is customary to delineate flower beds, lawns and pathways with masonry edgings made from a series of bricks, masonry blocks or a combination of edging elements cast out of cement. The installation of those types of edgings requires considerable time and a variety of building elements, as well as some masonry skill.

Descriptio~ of the Preferre~ ~kQ~i~ents of the Trlver~ti or~
- Referring now to the drawing, there is shown in Figure 1 a section of a series of blocks 10 . . .
separated by joint-washers 11 according to the invention, forming an edging between a lawn area 12 and a garden path area 13.
Each block 10 is made of molded plastic as illustrated in Figures 3-7. Each block essentially consists of a rectangular polyhedron having the general dimensions and color of a standard ~ construction brick approximately 20.4 centlmeters - WO95/08257 2 1 7 1 5 3 3 PCT~S93/08871 (7 inches) long, 8.8 centimeters (3 1/2 inches) wide, and 5.7 centimeters (2 1/4 inches) high; or of a closely similar oblong construction block.
For esthetical reasons, each block may be colored to preferably resemble a new or used brick. Each block 10 comprises a roof 14, a pair of parallel end-walls 15, 16, and a pair of side-walls 17, 18.
The end-walls and the side-walls extend orthogonally and downward from the periphery of the roof 14 to define an interior cha-mber 19 having an open bottom.
A substantially rectangular interconnecting element 20 extends orthogonally and outwardly from the center of the right end-wall 15. The interconnecting element 20 has a vertical cross-section which tapers down slightly from its root 21 on the face of the right side-wall to its distal end 22. A pair of aligned pins or nibs 23, 24 project upwardly and downwardly from the upper and lower surfaces of the interconnecting element. The center of the interconnecting element forms a hollow channel 25 in commllnication with the block internal chamber 19.
The left end-wall 16 has a rectangular cavity - w095/08257 2 1 7 1 5 3 3 PCrrUSs3/0887l 26 which is shaped, positioned and dimensioned to engage over the interconnecting element 25 of an adjacent block. The height of the cavity 26 is substantially equivalent to the height of the interconnecting element 20 near its root 21. The width of the cavity 26 is slightly larger than the overall width of the interconnecting element 20.
The internal upper surface 27 and lower surface 28 of the cavity 26 have aligned oblong windows 29 and 30 respectively which are sized and positioned to engage nibs 23, 24 of the adjacent block interconnecting element 20. Due to the rotational connection between the nibs 23, 24 and the windows 29, 30 respectively, the width of the windows 29 and 30 corresponding to approximately one-third of the total width of the block 10, and the fact that the width of the cavity is larger than the width of the interconnecting element, two adjacent blocks can be connected in a hinged manner allowing horizontal arcuate movement of one block in relation to the other in order to create curved edging sections as illustrated in Figure 1.
Rectangular washers 11 made of compressible material such as natural or synthetic r-lbber, ` - W095l08~7 2 1 7 1 5 3 3 PCT~S93/08871 natural or synthetic foam and elastomers are slipped over the interconnecting element 20 of each block to serve as a buffer, and simulate cement joints between the blocks 10.
Two prongs 31, 32 extend downwardly from the undersurface 33 of the roof beyond the lower edge 34 of the block. Each prong has a pointed and barbed distal section 35, 36. The prongs are used to anchor each block to the underlying supporting surface. That supporting surface may be a natural one such as turf or solid, some prepared aggregate or cementitious medium. Prongs 31, 32 are stabilized by two cross-bars 37, 38 spanning the two side-walls 17, 18 near the lower edge 34 of the box and the midsections of the prongs.
Figure 8 illustrates a block 39 which is traversed by a section of illuminating strip 40 of the type having bulbs 41 at regular intervals enclosed along with the wiring in a transparent tubing 42. The block 39 is preferably made of a transparent material, and a whole series of them can be strung like beads over the illuminating strip, passing through the channel 25 of the interconnecting element, internal chamber 19, and - woss/08257 2 1 7 1 S 3 3 PCT~ss3/08871 the cavity 26.
The alternate embodiment 43 of the block illustrated in Figures 9-13 is characterized by two symmetrical cavities 44, 45 in opposite end walls 46, 47. These cavities are substantially similar to the rectangular cavity 26 in the left wall of the first-described embodiment. A separate interlocking member 48 is used to hingedly join two of such blocks. The interlocking member 48 has a quadrangular central portion 49 and a pair of symmetrical, tapered projections 50, 51 extending in opposite axial directions from said central portion. Each of said projections is substantially similar to the interconnecting element 20 of the earlier-described embodiment. The vertically aligned pairs of nibs or stubs 52, 53 and 54, 55 - that extends from the top and bottom surfaces of each projection are shaped, dimensioned and positioned to snap into the corresponding pairs of recesses 56, 57 and 58, 59 respectively of two adjacent blocks. The insertion of the projections 50, 51 into the cavities 44, 45 is facilitated by the outwardly tapering of the projections. It should be noted that the projections 50, 51 have a `~~ WO95t08257 ~ 5 3 3 PCT~Ss3/0887l height substantially commensurate with the height of the cavities 44, 45, but a smaller width in order to allow limited rotation of the interconnecting element within the cavities about the vertical axes of the ribs and recesses.
An equivalent mode of attachment can be .
achieved by providing cavities or recesses in the projections of the interlocking member and placing the mating nibs or stubs inside the block.
An end cap 60 is provided to close the end - wall of a last one of a series of interlocked blocks. The end cap has a cover 61 commensurate with the outer dimensions of the end walls 46, 47 and a plug 62 shaped and ~ir^~Rioned to be forcedly engaged into the opening of either one of the cavities 44, 45.
While the preferred embodiments of the invention have been described, modifications can be made and other embodiments may be devised without departing from the spirit of the invention and the scope of the appended claims.

Descriptio~ of the Preferre~ ~kQ~i~ents of the Trlver~ti or~
- Referring now to the drawing, there is shown in Figure 1 a section of a series of blocks 10 . . .
separated by joint-washers 11 according to the invention, forming an edging between a lawn area 12 and a garden path area 13.
Each block 10 is made of molded plastic as illustrated in Figures 3-7. Each block essentially consists of a rectangular polyhedron having the general dimensions and color of a standard ~ construction brick approximately 20.4 centlmeters - WO95/08257 2 1 7 1 5 3 3 PCT~S93/08871 (7 inches) long, 8.8 centimeters (3 1/2 inches) wide, and 5.7 centimeters (2 1/4 inches) high; or of a closely similar oblong construction block.
For esthetical reasons, each block may be colored to preferably resemble a new or used brick. Each block 10 comprises a roof 14, a pair of parallel end-walls 15, 16, and a pair of side-walls 17, 18.
The end-walls and the side-walls extend orthogonally and downward from the periphery of the roof 14 to define an interior cha-mber 19 having an open bottom.
A substantially rectangular interconnecting element 20 extends orthogonally and outwardly from the center of the right end-wall 15. The interconnecting element 20 has a vertical cross-section which tapers down slightly from its root 21 on the face of the right side-wall to its distal end 22. A pair of aligned pins or nibs 23, 24 project upwardly and downwardly from the upper and lower surfaces of the interconnecting element. The center of the interconnecting element forms a hollow channel 25 in commllnication with the block internal chamber 19.
The left end-wall 16 has a rectangular cavity - w095/08257 2 1 7 1 5 3 3 PCrrUSs3/0887l 26 which is shaped, positioned and dimensioned to engage over the interconnecting element 25 of an adjacent block. The height of the cavity 26 is substantially equivalent to the height of the interconnecting element 20 near its root 21. The width of the cavity 26 is slightly larger than the overall width of the interconnecting element 20.
The internal upper surface 27 and lower surface 28 of the cavity 26 have aligned oblong windows 29 and 30 respectively which are sized and positioned to engage nibs 23, 24 of the adjacent block interconnecting element 20. Due to the rotational connection between the nibs 23, 24 and the windows 29, 30 respectively, the width of the windows 29 and 30 corresponding to approximately one-third of the total width of the block 10, and the fact that the width of the cavity is larger than the width of the interconnecting element, two adjacent blocks can be connected in a hinged manner allowing horizontal arcuate movement of one block in relation to the other in order to create curved edging sections as illustrated in Figure 1.
Rectangular washers 11 made of compressible material such as natural or synthetic r-lbber, ` - W095l08~7 2 1 7 1 5 3 3 PCT~S93/08871 natural or synthetic foam and elastomers are slipped over the interconnecting element 20 of each block to serve as a buffer, and simulate cement joints between the blocks 10.
Two prongs 31, 32 extend downwardly from the undersurface 33 of the roof beyond the lower edge 34 of the block. Each prong has a pointed and barbed distal section 35, 36. The prongs are used to anchor each block to the underlying supporting surface. That supporting surface may be a natural one such as turf or solid, some prepared aggregate or cementitious medium. Prongs 31, 32 are stabilized by two cross-bars 37, 38 spanning the two side-walls 17, 18 near the lower edge 34 of the box and the midsections of the prongs.
Figure 8 illustrates a block 39 which is traversed by a section of illuminating strip 40 of the type having bulbs 41 at regular intervals enclosed along with the wiring in a transparent tubing 42. The block 39 is preferably made of a transparent material, and a whole series of them can be strung like beads over the illuminating strip, passing through the channel 25 of the interconnecting element, internal chamber 19, and - woss/08257 2 1 7 1 S 3 3 PCT~ss3/08871 the cavity 26.
The alternate embodiment 43 of the block illustrated in Figures 9-13 is characterized by two symmetrical cavities 44, 45 in opposite end walls 46, 47. These cavities are substantially similar to the rectangular cavity 26 in the left wall of the first-described embodiment. A separate interlocking member 48 is used to hingedly join two of such blocks. The interlocking member 48 has a quadrangular central portion 49 and a pair of symmetrical, tapered projections 50, 51 extending in opposite axial directions from said central portion. Each of said projections is substantially similar to the interconnecting element 20 of the earlier-described embodiment. The vertically aligned pairs of nibs or stubs 52, 53 and 54, 55 - that extends from the top and bottom surfaces of each projection are shaped, dimensioned and positioned to snap into the corresponding pairs of recesses 56, 57 and 58, 59 respectively of two adjacent blocks. The insertion of the projections 50, 51 into the cavities 44, 45 is facilitated by the outwardly tapering of the projections. It should be noted that the projections 50, 51 have a `~~ WO95t08257 ~ 5 3 3 PCT~Ss3/0887l height substantially commensurate with the height of the cavities 44, 45, but a smaller width in order to allow limited rotation of the interconnecting element within the cavities about the vertical axes of the ribs and recesses.
An equivalent mode of attachment can be .
achieved by providing cavities or recesses in the projections of the interlocking member and placing the mating nibs or stubs inside the block.
An end cap 60 is provided to close the end - wall of a last one of a series of interlocked blocks. The end cap has a cover 61 commensurate with the outer dimensions of the end walls 46, 47 and a plug 62 shaped and ~ir^~Rioned to be forcedly engaged into the opening of either one of the cavities 44, 45.
While the preferred embodiments of the invention have been described, modifications can be made and other embodiments may be devised without departing from the spirit of the invention and the scope of the appended claims.
