Description
kat (PATAPPS) DOCKET: P-6306-10 BACKGROUND OF THE INVENTION
The present invention relates to an improvement in pavement edging, and, in particular to an improved pavement edging for use with concrete paving bricks.
In my co-pending application serial no.: 09/116,824, filed July 16, 1998, entitled Pavement Edging, there is disclosed a pavement edger comprising a base, an elongated front wall, an elongated rear wall and a plurality of interposed longitudinal and transverse walls forming a generally egg crate construction between the front and rear walls. The front wall is offset from the edge of the base to provide an apron on which the pavement, generally brick, is laid in abutment with the front wall. The pavement edger being back-filled to bury the pavement edger. The pavement edger disclosed in the above-mentioned application is made in an endless length and is cut-in-situ to conform to the length of the pavement.
t w It is this generally endless construction that provides manufacturing difficulties, particularly for construction of the egg crate interior. Further, the egg crate construction which maintains strength and stability in the edger is difficult to back-fill when the back-fill employs grand or large soil clumps.
It has also been found that the manner by which the pavement edger is secured to the ground requires a great deal of attention, which is difficult under field conditions.
Additionally the cost of storing and transporting endless lengths of pavement edger is high.
'It is therefore amongst the objects and purposes of the present invention to provide an improved pavement edger overcoming the limitations noted above.
These objects, and other objects and advantages will be apparent from the following disclosure.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
In Figure 1, a plurality of concrete bricks B aligned in pavement pattern are laid on a prepared base. The base comprises a first layer C consisting of crushed concrete, gravel and a second layer of sand S laid on top of a level ground G. The bricks abut on both sides against a stretch of lawn L. As so far described, the installation is conventional and quite common in the art.
In order to maintain the integrity of the pavement and the maintenance of a straight longitudinal edge, a pavement edging according to the present invention, generally depicted by the numeral 10, is interposed between the bricks B and the lawn L along both longitudinal edges of the paved surface.
For purposes of simplicity a single pavement edging 10 is shown in Fig. 1, however it is appreciated that an edging according to the present invention would be installed along both longitudinal edges of the paved surface in use.
As seen in Figures 1 and 2, the pavement edging according to the present invention comprises a buttress, of definite length such as for example 36 inches, 48 inches or other selected lengths, having a horizontal bottom wall 14, a vertical front wall 16 facing the bricks, a vertical rear wall 18 facing the lawn and a plurality of transversely arranged interior walls 20 spaced uniformly between each of its end walls 22 interposed between the front and rear walls 16 and 18.
The front wall 16 is higher than the rear wall 18 and the transverse interior walls 20 are graduated in height giving the buttress a smooth slope from front to rear. While graduated walls are shown, any type of wall may be utilized.
The front wall 16 is offset back from the inner most terminal edge of the bottom wall by a slight amount so that the bottom wall forms an extended apron 24. The rear wall 18 extends vertically from the outermost terminal edge of the bottom wall as seen.
Integral with the front wall 16 and the apron 24 are a plurality of vertical studs 26. The studs 26 are preferably aligned with the interior wall 20 and the end walls 24, between adjacent transverse walls 20 and end walls 22.
The bottom wall 14 is relieved of a section 28 leaving a relatively large open space, although a trapezoid is shown any other geometrical relief can be made. Similarly, the apron 24 is relieved along its free edge in a geometrical pattern conforming a spatial cut-out 30 aligned with the sections 28.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
In Figure 1, a plurality of concrete bricks B aligned in pavement pattern are laid on a prepared base. The base comprises a first layer C consisting of crushed concrete, gravel and a second layer of sand S laid on top of a level ground G. The bricks abut on both sides against a stretch of lawn L. As so far described, the installation is conventional and quite common in the art.
In order to maintain the integrity of the pavement and the maintenance of a straight longitudinal edge, a pavement edging according to the present invention, generally depicted by the numeral 10, is interposed between the bricks B and the lawn L along both longitudinal edges of the paved surface.
For purposes of simplicity a single pavement edging 10 is shown in Fig. 1, however it is appreciated that an edging according to the present invention would be installed along both longitudinal edges of the paved surface in use.
As seen in Figures 1 and 2, the pavement edging according to the present invention comprises a buttress, of definite length such as for example 36 inches, 48 inches or other selected lengths, having a horizontal bottom wall 14, a vertical front wall 16 facing the bricks, a vertical rear wall 18 facing the lawn and a plurality of transversely arranged interior walls 20 spaced uniformly between each of its end walls 22 interposed between the front and rear walls 16 and 18.
The front wall 16 is higher than the rear wall 18 and the transverse interior walls 20 are graduated in height giving the buttress a smooth slope from front to rear. While graduated walls are shown, any type of wall may be utilized.
The front wall 16 is offset back from the inner most terminal edge of the bottom wall by a slight amount so that the bottom wall forms an extended apron 24. The rear wall 18 extends vertically from the outermost terminal edge of the bottom wall as seen.
Integral with the front wall 16 and the apron 24 are a plurality of vertical studs 26. The studs 26 are preferably aligned with the interior wall 20 and the end walls 24, between adjacent transverse walls 20 and end walls 22.
The bottom wall 14 is relieved of a section 28 leaving a relatively large open space, although a trapezoid is shown any other geometrical relief can be made. Similarly, the apron 24 is relieved along its free edge in a geometrical pattern conforming a spatial cut-out 30 aligned with the sections 28.

To anchor the buttress 12 to the ground, a transverse band 32 is laid between the concrete base C and the layer of sand S as seen in Fig. 1. The transverse band 32 comprises an elongated band constructed of a durable synthetic material such as PVC or the like. Preferably, the dimensions of the band are approximately 1/4" thick and about 2" wide. These dimensions of course may be varied as desired depending upon the needs of a particular application. Uniformly arranged along the length of the of the band 32 are a plurality of through slots 34, all transverse to the length of the band, the front end of the band 32 is provided with perpendicularly intersecting slots 36 forming a cross, into which an enlarged cruciform stake 38 is driven. The stake 38 is tapered and shaped to provide easy driving into the ground.
In use, a plurality of bands 32 are laid along the length of the pavement. Each band 32 that is laid is secured to the ground by driving a plurality of stakes 38 through the slots 36 into the ground surface. The buttress 12 is then laid in the desired location on top of the transverse band 32. The buttress 12 is positioned on the band 32 by driving stake 40 over the edge of the longitudinal front wall 16, to depend on the inner surfaces and pass through the spaces created by the reliefs 28.
Similarly, stakes 40 are placed over the outer surface of the rear wall 18. The stakes 40 are sufficiently long so as to pass a significant distance into the ground to be held there. The stakes 40 in the bottom wall of the buttress align with the holes 32 in the band as shown in Fig. 2. As seen the head of the stake 40 may be configured such that it conveniently folds over the front wall 16 as shown. The stakes 40 are provided with barbs 42 along their lengths which act as cleats binding the stakes to the ground and also to the bands 32 or buttress 12.
As earlier noted the buttress 12 and the transverse bands 32 are formed of discrete lengths. Therefore, in normal manual installations more than one band or buttress must be placed in tandem to insure that each tandem is in alignment and is securely fitted against dislodgement or movement.
Therefore, the bands 32 and buttresses 12 are made with interlocking cooperatingly coupled ends.
For example, as seen from the figures, the buttress lengths are provided with integral T shaped male members 44 at one end and female recesses 46 at the other end. The male members and female recesses 44 and 46 permit one to slide into and be held by the other. Also, the rear wall 18 is provided with a lip 48 projecting from one end wall 22 and a U-shaped female member 50 projecting from the opposite end wall 22. In use, the female member 50 slides over the lip 48 in order to further hold the tandem of buttresses 12 together. Thus a continuous line of two or more buttresses can be attached along the wire.
In Fig. 5, the band 32 is provided at one end with a T
shape male member 52 and at its other end with a female slot 54, defined by a pair of spaced longitudinal edges and a raised end cross member which requires the T shape male member 52 to be twisted into locking engagement into the slot 54.
Alternatively, as seen in fig. 6, the male member 56 can comprise a tongue 58 with an L-shaped portion 58 extending downward and forward for engagement into a slot 60 formed at the opposite end of another band 32.
It will be seen from Fig. 3 that the inclined transverse walls 22 terminate below the top edge of the front and rear walls 16 and 18. This construction allows the discrete length of buttress 12 to be easily stacked one on top of the other, e.i. inverted and reversed in mirror image.
The cut-out portions 30 in the apron 24 as seen in Fig.
4 enable the discrete length buttress 12 to flex arcuately so as to enable it to follow the curve of the pathway.
It will be noted that the front wall is provided with vertical studs 26 which extend a short distance forward over the apron 24. Thus, when the buttress 12 is placed in abutment with the bricks of the path, the bricks actually abut against the stud 26 leaving a series of small spaces between the brick face and the front wall 16. The spaces can then be easily filled with a resin saturated aggregate or other binding preparation adhering both to the buttress 12 and the brick. In this manner a more uniform and unitary connection between the buttress 12 and the pathway can be formed.
Alternatively, studs 26 can operate as a spacer, providing room f or the pavement to expand into during the winter or when the pavement approaches freezing temperatures.
Additionally, as seen in fig. 7, a plurality of evenly spaced teeth 62 are integrally formed on the bottom surface of the bottom wall 24 as well as on the top surface of each band 32. The teeth 62 on each member cooperate with one another and allows the buttress 12 to be snapped on to the bands 32. Thus eliminating the need for stakes 40 to be used to secure the buttresses 12 to the band 32.
Various modifications and changes of the present invention have been disclosed herein and others will be apparent to those skilled in this art. Therefore, it is to be understood that the present disclosure is by way of illustration and not limiting the present invention.
