Definitions

  • This invention relates to the field of garden and lawn supplies and, more particularly, to an improved weed barrier.
  • U.S. Patent No. RE 33,037 issued to Kauffman et al. on August 29, 1989 discloses a fence liner.
  • Kauffman' s invention lacks a reinforced edge portion to protect the fence liner from damage by mower blades.
  • Kauffman's system also lacks a connection system to connect sections of the fence liner together.
  • Kauffman's system has a trough in the middle of the fence liner running the length of the fence liner that can allow water or soil to collect, resulting in a dirty fence liner and possibly providing a breeding ground for mosquitoes and other insects.
  • the trough section of the Kauffman's fence liner gives Kauffman's fence liner a non-continuous top surface.
  • a fence liner for placement on the ground to prevent the growth of plant material in the area underneath the placed fence liner, is disclosed.
  • the fence liner has a fixed width and a length to cover a desired area.
  • the fence liner includes a top portion, a bottom portion and two reinforced edge sections running the length of the fence liner and contacting the ground.
  • Two or more support sections are provided.
  • the two or more support sections are formed along the length of the fence liner.
  • a base of each support section contacts the ground.
  • a first portion of the fence liner is placed along a vertical surface and a second portion is placed along the ground. This is useful to prevent the growth of plant materials near walls or buildings. It also provides a moisture barrier near walls.
  • an apparatus to prevent the growth of weeds includes an opaque plastic barrier having a fixed width and a length.
  • the barrier includes a first portion and a second portion, the first portion and the second portion dividing the barrier along the length of the barrier.
  • the plastic barrier includes a top portion and a bottom portion. Also included is a plurality of reinforced edge sections that contact the ground and at least a pair of support sections running the length of the apparatus. A base of each support section contacts the ground.
  • a wall protection barrier is provided.
  • the wall protection embodiment includes a first portion operable to be attached to a vertical surface and a second portion operable to be positioned on a ground surface. The second portion prevents the growth of plant material near the vertical surface.
  • FIG. 1 is a cutaway view of a weed barrier
  • FIG. 2 is a view of topside of a weed barrier
  • FIG. 3 is a view of the underside of a weed barrier
  • FIG. 4 illustrates a tab connector
  • FIG. 5 illustrates a weed barrier in use under a fence
  • FIG. 6 is an overhead view of a weed barrier in use with a fence
  • FIG. 7a and FIG. 7b illustrates a weed barrier with a connector to connect multiple sections
  • FIG. 8a and 8b illustrate alternative embodiments of a weed barrier
  • FIG. 9 illustrates an embodiment of the invention used as a wall liner against a wall
  • FIG. 10 illustrates an embodiment for connecting the embodiment of FIG.
  • FIG. 11 illustrates an alternative embodiment of the wall liner.
  • An improved weed barrier provides a way to keep grass and weeds from growing under fences or near walls.
  • the improved weed barrier when placed in areas where weed growth or other plant growth is undesired, such as under a fence prevents the growth of grass and weeds by blocking sunlight and preventing water from reaching the grass and weeds or other plant material. Without sunlight, existing weeds will die and any existing weeds will die and any existing plants will not germinate. If weed or plant growth occurs, it will not be able to penetrate the weed barrier. This allows for a neat appearance under the fence.
  • An improved weed barrier according to various aspects of the present invention, generally is formed from a flexible opaque plastic material.
  • the weed barrier may be produced in large lengths and then cut to fit a specific size and type of fence.
  • the weed barrier is curved to allow rain and debris to readily drain off. Sections of weed barriers may be connected together using tab connectors.
  • the weed barrier is easy to install with no or few tools required for installation.
  • the weed barrier can be made in a color close to that of the lawn to present a pleasing appearance.
  • the weed barrier may also be used as a wall liner with a first section contacting the wall and a second section contacting the ground. This prevents weed and grass growth near walls. [0025]
  • weed barrier 10 has a length, L, and a width, W.
  • the length, L, of the weed barrier 10 may be any length desired to cover a desired area such as the area between the two fence posts.

  • weed barrier 10 is manufactured with a width, W, of approximately five inches.
  • Other widths can be manufactured, depending on such factors as the type of fence the weed barrier 10 is to be placed under and the desired size of the weed free area. For example, eight-inch widths and ten-inch widths can be made.
  • the length, L can be made to any size to cover a given area such as the area between two fence posts.
  • weed barrier 10 can be provided in fixed lengths, such as four-foot sections.

For example, a homeowner may want the handling ease of-shorter sections while a contractor may prefer longer lengths.
  • Weed barrier 10 can also be provided in large rolls and cut to fit.
  • Weed barrier 10 includes a first side 40 and a second side 42, each side running along the length, L, of the weed barrier on either edge of the width, W, of the weed barrier.
  • Weed barrier 10 is preferably made from a plastic such as polyethylene, high density polyethylene (HDPE), low density polyethylene, a combination of plastic materials or rubber material although any material can be used that is able to withstand potential damage from lawn mowers and weather extremes as well as able to stop plant material from growing through it. In one embodiment weed barrier 10 is manufactured using recycled plastic material. Weed barrier 10 is preferably made to be opaque to block sunlight.

Once extruded, weed barrier 10 can be cut into individual strips of materials as needed or left in large rolls. Weed barrier 10 can be made in different colors and with different patterns formed on the weed barrier 10. Weed barrier 10 can be made to match the surrounding grass or to appear to be brick or other material. For example, weed barrier 10 can be made in a green color to match the color of grass.
