DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-8, aspects of the landscaping walls, systems and methods are shown. FIG. 1 depicts a landscaping wall 20 installed adjacent a building. In the present case wall 20 is used in part as a retaining wall. Wall 20 includes a front side 22 which includes a molded decorative design simulating brick or rock. The design may also include simulated stone or lumber or other simulated materials. The wall 20 may be curved or straight and have stepped height or be of a uniform height.
FIG. 2 shows the wall 20 and a back side 24 containing a passageway 31. The passageway 31 is oriented generally vertically at the back side 24. In this example the passageway 31 is formed using a conduit 30. In one aspect conduit 30 includes a piece of PVC conduit 32. Conduit 30 may also be made of other materials. For instance, conduit 30 may be a flexible hose, such as a garden hose, or a cardboard tube or insert, or other object or filler material that allows for formation of a passageway 31. In one aspect a polyvinylchloride or PVC conduit 32 is positioned at the back of wall 20 and bonded to the wall 20 during fabrication of the wall 20. In one aspect the wall is fabricated in part by applying fiberglass and other materials. Several layers of fiberglass or other materials are used to form the wall 20 which is often cured within a mold in order to create a desired decorative pattern on the front side 22. In one aspect conduit 32 is embedded at the back side 24. Using fiberglass to embed conduit 32 provides a solid structural support. Multiple layers of fiberglass may be applied (for instance, by spraying) on the back side of wall 20, where the buildup of the fiberglass rigidly embeds the conduit 30 into the wall 20. Open opposite ends 34 of conduit 32 are left open during the manufacture and curing process (or are temporarily capped or plugged so the openings do not close during the fabrication process).
In one aspect the passageway 31 is formed by embedding a PVC conduit 32 into the fiberglass layer of the wall 20. In one aspect the PVC tube has a length of about 12 inches and diameter of ½ inches. Other lengths and sizes may be used. In one aspect where conduit 30 has a length of about 12 inches, a top portion of the conduit 30 will be positioned at least 4 inches from an uppermost portion of the wall 20, and a bottom portion of the conduit 30 will be positioned at least 4 inches from a lowermost portion of the wall. In other aspects, the distance between the conduit 30 and the upper or lowermost portions is between 8 and 9 inches. In a case where the total height of wall 20 measures 31 ½ inches, the conduit 30 may measure about 12 inches, leaving a gap of about 8 to 9 inches between the conduit 30 and the upper and lowermost portions of the wall. Various configurations or measurements of the gaps may be used depending on the case. Providing the conduit 30 in the middle portion (measured vertically) of the wall 20 as described (i.e., with gaps between the top and bottom edges) provides a desired structural advantage. Use of a rigid plastic such as PVC for the conduit 30 has a structural advantage also as compared to use of a cardboard tube or an angled cardboard bridge or other material. For instance, a folded cardboard, such as folded at 90 degrees may also be used as a tent-like structure to create a passageway along the back side 24. Such folded cardboard may also be layered with fiberglass to embed the cardboard within the layers and create a resulting passageway. Yet PVC has been found to work better for most purposes because the PVC conduit 30 will not tear (or most likely will not tear) when forces from the cable or line 40 are applied to the conduit 30. Use of a cardboard element to create the passageway will tend to result in tearing or potential tearing of the fiberglass due to forces applied by the cable 40. Moreover, utilizing a conduit 30 having a length of about 12 inches is desirable compared to, say a 4-inch-long variety, due to an increase strength and rigidity of affixing a longer length of PVC into the layers of fiberglass. Moreover, the 12-inch PVC allows for the cable to exit the passageway and connect to the stake 50 while applying angular forces originating at the respective ends of the conduit 30 having the relatively wider spacing of about 12 inches. This spacing of 12 inches also accommodates a more natural fixing to a strong middle region of the stake 50. The conduit 30 of about 12 inches allows for an improved distribution of the holding or resisting forces associated with the stake 50. In aspects, positioning the loops 40 of the cable 40 at about 12 inches to correspond to the length of the conduit 30 provides a desired structural or supporting benefit. Of course, conduit 30 having a length shorter or longer than about 12 inches is also contemplated for use.
Conduit 30 includes a passageway 31 through which a line 40, such as a rope or cable or wire or metal line passes. In one aspect line 40 is a metal cable having opposite ends 42 formed into loops 44.
As shown in FIG. 2 and FIG. 3, a stake 50 is inserted into respective loops 44 of line or cable 40 and the stake is pounded into the ground or surface 75 adjacent wall 20. Particularly, wall 20 is positioned at a desired depth with respect to a building, for instance. The ground upon which wall 20 is positioned is leveled. A gravel such as pea gravel inserted at the ground location to assist in leveling and for water draining. Gravel or other sand or soil is compacted as desired or as needed prior to application of wall 20 or for backfilling of wall 20. Stake 50 is inserted through respective loops 44 of cable 40 and pounded into the ground adjacent wall 20. As stake 50 is pounded, the cable 40 tightens or is otherwise secured into position so that wall 20 is also fixed into position, thus sufficiently and confidently anchoring wall 20. In one aspect stake 50 includes wings 52 upon which loops 40 catch. When pounding stake 50, the wings 52 pull downward on cable 40 to assist in tightly securing the cable 40 and setting the wall 20. While stake 50 shown in FIG. 2 depicts wings 52 at an upper portion of the stake 50, it may be appreciated that the stake 50 may be flipped upside-down so that the wings 52 are positioned closer to the ground when pounding the stake 50. In such case the wings 52 will catch the lower aspect of the cable 40 toward the ground for secure mounting. In further aspects, stake 50 will include fingers or hooks at a backside of the stake which catch the cable 40 so that cable 40 will not easily adjust or slide along the stake 50. In yet further aspects, the ability of the cable 40 to slide within passageway 31, allows for automatic self-adjustment of the cable 40 when pounding of the stake 50. The ability of the cable 40 to also slide along stake 50 in some instances also allows for automatic self-adjustment. FIG. 3 shows wings 52 of stake 50 securing cable 40 while cable 40 is pulled tight against conduit 30 to anchor the wall 20 to the ground and resist movement due to forces that will be applied to the wall 20.
Wall 20 may include multiple conduits 30 for like-anchoring along the length of the wall 20. In one aspect a wall 20 includes two conduits 30. In one aspect conduit 30 is oriented substantially vertically on back side 24 such that cable 40 passing through conduit 30 will also be oriented generally vertically. Such vertical orientation accommodates efficient securing of cable 40 to stake 50 and a strong anchoring force applied to wall 20. Conduit 30 may also be positioned horizontally or at other angles as desired, yet vertical orientation accommodates securing both ends of the line 40 with a single stake 50 (or the vertical configuration allows for a more efficient tightening of the cable when pounding the stake). The conduit 30 and line 40 are not visible from the front side 22. In one aspect conduit PVC 32 is removable. In further aspects PVC 32 is bolted or otherwise connected to wall 20.
FIG. 4 shows a backfill of soil 75 or gravel behind wall 20 and depicts stake 50 and cable 40 prior to being covered with gravel 80. Wall 20 includes a top flange 26 and opposite vertical mounting flanges 28. Mounting flanges 28 (also shown in FIG. 3) may include holes for securing wall 20 to a house or foundation of for connecting to another wall 20. Several walls 20 may thus be bolted together as desired. In one aspect a metal strip 60 or pair of strips 60 are used to reinforce mounting flanges 28. In one aspect strips 60 sandwich the flange 28 and include holes through which fasteners such as cement or other bolts pass and secure the flange 28 to a foundation or other wall 20.
FIG. 5 shows wall 20 having gravel and soil back filled to the back side 24 of wall. The soils may be compacted such as with a compactor 70. Additional landscape or topsoil or rocks or chips or other material is added for a finished look.
FIG. 6 shows a further aspect of a straight wall 20 (without a curve as in FIG. 1) having conduit 30 embedded at back side 24. Cable or line 40 inserts through conduit 30 and has loops 44 at opposing ends and ready for insertion upon or otherwise connecting to a stake to be used to anchor wall 20. Strips 60 are used in conjunction with bolts, washers and nuts to reinforce mounting flange 28. A bottom flange 27 extends from a bottom of wall 20 and rearward of front side 22. Bottom flange 27 rests upon the ground surface which is leveled for placement of wall 20. Wall 20 is designed to stand upright on its own by resting upon bottom flange 27. The front side 22 includes the decorative design, and a portion or aspects of such design, although not entirely clear due to the bonding or fiberglass application process, are shown slightly in FIG. 6 at back side 24. In one aspect the PVC tube 32 has a length of about 10 to 24 inches depending on the desired size of wall 20, and in more particular aspects a length of about 12 inches, and in further aspects longer lengths, including lengths of 18 inches to 24 inches and a diameter of ½ inch. Different lengths and sizes may be used as desired or needed.
FIG. 7 shows a further aspect of the wall 20 and system 21 of the invention, including a pair of walls 20 connected together at mounting flange 28 and having a pair of conduits 30 positioned at back side 24. A pair of stakes 50 are used in conjunction with the pair of conduits 30 and lines 40 to anchor wall 20 to the ground. Top flange 26 and mounting flanges 28 may also include a decorative design. A trench 72 is dug (or already exists) into which wall 20 is positioned, and filled and leveled with sand or gravel or soil. Stakes 50 (and the back side 24 of wall 20) are back-filled with gravel and soils to secure walls 20 into position. As further presented, a first conduit 30 and second conduit 30 are positioned toward outside flanges 28 of the wall 20. Such positioning allows for anchoring the wall in a generally balanced manner and provides sufficient anchoring support. In addition to the first and second conduits 30, 30, a third conduit 30′ may also be provided at back side 24 of wall 20 at a position between the first and second conduits 30, 30. This third conduit 30′ provides additional structural integrity to the wall 20, even though it is not or might not be used for anchoring. Particularly, in one aspect the third conduit 30′ is also embedded within a fiberglass layer of wall 20, yet lacks respective open ends. Conduit 30′ may define a passageway 31, but such passageway is closed at both ends. Thus, in a situation where an installer purchases a wall 20 as a system or a kit (with instructions or with reference to online video instructions for installation), and the system or kit includes only two respective cables 40 and stakes 50 per wall 20, the user will not mistakenly install the cable 40 into an otherwise open third conduit 30′. Instead, the installer will utilize the open passageways of the respective first and second conduits 30 for a balanced anchoring. Of course, in some applications the third conduit 30′ may also include an open passageway 31 for receipt of an anchor line. In further aspects, additional conduits 30, 30′ may also be provided to a wall 20 for further anchoring and/or structural support.
FIG. 8 shows a pair of stakes 50 connected to lines 40 which extend from respective adjacent conduits 30. Stakes 50 may include wings 52 or clips or other mechanisms for further securing line 40 to stakes 50. While the cable 40 depicted in FIG. 8 is shown to be positioned above wing 52, in alternatives the cable 40 may be positioned below wing 52 so that it may be more effectively tightened when stake 50 is pounded downward into the ground. In one aspect cable 40 is a braided wire cable or a strap having a loop 44 or loops 44 created by wrapping the cable or strap upon itself and securing with a cable nut or connector.
In further aspects wall 20 is made of different materials (in addition to, or instead of, fiberglass) including, for instance, wood, metal, plastic or composites.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
