Description
Field of the Invention
The present invention relates to brick edging devices.
Background of the Invention
The need for brick edging devices to separate bricked areas from different kinds of terrain is well known. There are several basic types of brick edging devices utilized for a similar application, namely edging grassy areas. One type includes a single upright elongate strip with a horizontal flange member or a plurality of discrete individual flap members extending away from the elongate strip to provide support for the strip or an anchoring base for the device. However, edgers known in the prior art provided with these horizontal extending flanges or flaps have been designed so that the flange prevents bending of the strip or the flaps interfere with one another when the strip is bent, thereby limiting the angle to which the edger can be bent. Prior art edgers have also not been produced to accommodate standard size bricks when the strips are bent, but rely on the bricks being cut to provide a snug fit. Furthermore, in prior art edging devices, the horizontal flange or flaps or other means of support for the upright strip is commonly designed to remain uncovered by grass, brick or other substrate, thus producing a wide border between areas, comprising both the upright strip and the support means.
We have found that we can overcome these disadvantages in the prior art by providing a brick edging device that is provided with flaps that are configured and spaced to allow for bending of the strip to a variety of angles and can accommodate a brick of a standard size without the need for cutting of the brick to obtain a snug fit. In addition, our device, when in place, provides a sharp, well-defined boundary between the bordered areas.
Another type of prior art device in this class provides for the stabilization and securing of the elongate strip in an upright position using spikes or stakes with hooks at one end which hook over the upper edge of the strip. A drawback to this kind of arrangement is that during frost heaving the stake is driven up out of the ground and since the hook is securely interlocked with the strip, the strip is also dislodged from the ground. We have found that we can provide an improved snap fitting engagement between the stake and the edging strip so that, in the event of pressure due to heaving of the substrate, the hook will disengage from the strip rather than lift the strip from its position.
A single securing means is commonly inadequate to securely hold a strip in place at the boundary of a bricked region since there is considerable outward pressure acting on the bricks due to vehicles or people walking over the bricks. We have found that a dual means of securing the edging strip is preferable and have thus provided securing means both by way of a stake on one side of the strip and spike on the other side of the strip.
Connecting pieces joining lengths of brick edging are well known but have in the prior art, fixed the joined pieces in a manner prone to separation without accommodating changes in grade of the substrate on which the edger is fixed. Our connecting pieces overcome these disadvantages allowing for changes in grade. Also, many of the prior art devices are fabricated from plastics which are prone to splitting in cold weather or when struck during the installation step when driving spikes therethrough. Our device overcomes this disadvantage by being fabricated from materials resistant to splitting.
Summary of the Invention
The subject invention provides a brick edging device for use as an interface or boundary between a bricked region and other types of terrain.
In one aspect of the invention a brick edging device includes an elongate strip extending in a longitudinal direction and having first and second opposed sides and opposed edges.

Detailed Description of the Preferred and Alternative Embodiments
In referring to the drawings like numerals refer to like parts. A first embodiment of a brick edging device 10 embodying the subject invention is shown in FIGS. 1-4 and includes an elongate strip portion 12 having a substantially planar portion 14, a first edge 16, a second opposed edge 18, and wherein planar portion 14 includes opposed sides 20 and 22. Elongate portion 12 includes spaced, longitudinal strengthening ribs 24 and 26 integrally formed therewith and extending along the full length of strip 12. Preferably ribbed portions include a rounded outer portion 28 and adjacent rounded channel portions 30, see FIG. 4. Ribs 24 and 26 mitigate against crimping of strip 12 during bending.
Brick edger 10 is provided with a substantially planar flange member 32 connected to strip portion 12 along edge 16 thereof. Flange 32 extends transversely with respect to planar portion 14 and away from side 20. Flange 32 includes a plurality of flap members 34 separated from each other by V-shaped cut-out portions shown generally at 36. An apex 37 of the cut-out V-shaped portions is flat, not pointed, wherein the flat apex portions 37 are parallel edge 16 and spaced about 0.08 to 1.0 mm from edge 16 defining a projecting portion 39. Strip 12 may be bent or shaped by bending strip 12, inwardly or outwardly with respect to flaps 32, at points adjacent flat apex portions 37 as illustrated in FIGS. 1 and 2. The presence of projecting portion 39 mitigates against tearing or ripping of strip 12 when the latter is being bent or shaped.
The size of the flap members 34 and spacing between the cut-out portions may be chosen to correspond to the width of a known standard size brick so that a single brick may be bordered by the strip embodying the subject invention, see FIGS. 1 and 2.
In one embodiment of the brick edger there is an angle of about 90 degrees between the sides of adjacent flap members 34 so that strip 12 may be bent inwardly by 90 degrees. It will be appreciated that in other embodiments angles of greater than 90 degrees between the sides of adjacent flaps may be formed, thus allowing for bending of the strip 12 to angles greater than 90 degrees.
Flaps 34 are each provided with an aperture 38 which may be countersunk. Apertures 38 are of a suitable size to receive therein a spike 40. With countersunk apertures 38, a head portion 42 of spike 40 will be flush with the top surface of flap 34 when a spike is located in an aperture.
Edger 10 includes a plurality of retaining loop members shown generally at 44 located on side 22 of strip 12 each of which extends outwardly therefrom. A wall portion 46 of loop 44 has a thickness of D1. A plurality of planar stake members 48 are each provided with a planar shaft portion 50 wherein loops 44 and stakes 48 are suitably dimensioned so that shaft 50 may be received through loop 44. Stake 48 is provided at one end with a sharpened end 52 adapted to be driven into the ground and a hooked portion 54 located at the other end thereof Hooked portion 54 is provided with an inwardly projecting protrusion 56 thereby forming a gap 58 between shaft 50 and protrusion 56. Gap 58 is of a width slightly smaller than D1 so that when stake 48 is received by loop 44 hook portion 54 snaps over wall 46 of loop 44 thereby fitting stake 48 in loop 44 with the upper end portion of hook 54 located below edge 18. In this way stake 48 and loop 44 form a snap fitting combination so that stake 46 is inhibited against moving with respect to strip 12 absent the application of significant pressure to release the snap fit.
The embodiment of the brick edger shown at 10 in FIGS. 1-4 is bendable along strip portion 10 along lines in the plane of planar portion 14 at a plurality of positions, examples of which are shown at 60. Since there is at least a 90 degree angle between the edges of adjacent flap members 34, strip 12 may be bent by up to at least 90 degrees, see FIGS. 1 and 2.
Brick edger 10 is preferably fabricated from extruded aluminum with ribs 24 and 26, flange 32, flaps 34 and retaining loops 44 being integrally formed therewith at the time of fabrication.
In one embodiment, several individual strips 12 may be collinearly coupled together using ribbed securing brackets such as those shown at 64 in FIGS. 1 and 2. Strip 12 includes countersunk holes 66 with the latter providing a recess in which the head of a screw 68 may reside in order that bricks may be placed snug against strip 12.
In operation, brick edger 10 is first shaped or bent as desired and then secured to the ground at the boundary of a region where bricks or concrete blocks are to be placed. To secure edger 10 in place, spikes 40 are driven through apertures 38 into the ground until spike head 42 is flush with the top surface of flap 34. Stakes 48 are inserted through retaining loops 44 until hooked end 54 grips loop wall 46 as previously disclosed to releasably lock stake 48 and strip 12 together. Bricks and the like may then be laid flush against strip 12 directly on top of flaps 34, as shown in ghost outline at 59 in FIGS. 1 and 2, rather than requiring a layer of sand or other spacing material.
Securing strip 12 on both sides thereof provides a more stable and secure brick edger so that strip portion 12 remains in the same position over time. When stake 48 is engaged in loop 44 strip 12 is inhibited from pivoting with respect to stake 48 in addition to which stake 46 acts to assist in maintaining strip 12 vertically upright at all times. Because stake 48 is releasably coupled to strip 12 it will snap free of strip 12, without being damaged, during frost heaving and the like, rather than both the strip and the stake being dislodged. Since the upper end of stake 48 is located below the upper edge of strip 12 the former will be rendered practically invisible when grass and bricks extend above upper edge 18 thereof.
FIG. 5 illustrates another embodiment of the brick edger at 70 comprising a plurality of short separate units 72 which may be attached to each other at 74 by brackets 76. Each unit 72 includes a flange 72 which is coextensive with strip 12, all other features being substantially the same as edger 10.
While the present invention has been described and illustrated with respect to the preferred and alternative embodiments, it will be appreciated that numerous variations of these embodiments may be made without departing from the scope of the invention, which is defined in the appended claims.
