Edging interface for a golf course bunker

Abstract

An edging interface for a golf course bunker includes a strip of backing divided longitudinally into a first portion and a second portion. The strip of backing is also laterally divided into a plurality of adjacent sections by a plurality of cuts, where each adjacent section is joined together at the first portion, and artificial turf is secured to the first portion. The second portion of each section is configured to be anchored between the golf course bunker and a grass edge of the golf course. The edging interface can be rolled up for handling and shipping, and unrolled in place for installation. The artificial turf comprises straight and curly yarn and has a color to match natural turf stacked bunker edges. In addition, the first portion and the second portion longitudinally divide the strip of backing into substantially equal portions.

DETAILED DESCRIPTION

(12) The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

(13) Referring now to FIG. 1, a cross sectional view of a typical golf course bunker 100 is shown having the edging interface 120 of the present invention installed. The edging interface 120 includes a strip of backing 122 divided longitudinally into a first portion 128 and a second portion 130. The strip of backing 122 is also laterally divided into a plurality of adjacent sections, where each adjacent section is joined together at the first portion 128, and artificial turf 124 secured to the first portion. The second portion 130 of each section is configured to be anchored between the golf course bunker and a grass edge 114 of the golf course.

(14) The bunker 100 includes a layer of sand 112 over a layer of porous concrete 110A, such as Capillary Concrete of the Applicant, that forms a liner for the bunker 100. The porous layer 110A terminates in a border that forms a ledge 110B around the bunker 100 and is proximate an interface between the bunker and grass 114 of the golf course. A top layer of porous concrete 110C anchors the edging interface 120 in place and creating a transition from the grass 114 to the bunker sand 112 that requires no maintenance and does not crumble. A drainage pipe 116 is located below the bunker 100 and configured to collect water and prevent ponding within the bunker.

(15) FIG. 2 is a detail view from the cross-sectional view of FIG. 1. The edging interface 120 is placed on the ledge 110B and the second portion of the edging interface 120 is anchored by the top layer 110C as best shown in FIG. 3. Soil 115 is filled in over the top layer 110C and at least a portion of the edging interface 120. Accordingly, the transition from the grass 114 to the bunker sand 112 is fully supported once the interface edging 120 is installed.

(16) The bottom surface of the edging interface 120 is shown in FIG. 4. As explained above, the edging interface 120 includes a strip of backing 122 having a first portion 128 and a second portion 130. The strip of backing 122 may comprise nonwoven polypropylene or any suitable material as those of ordinary skill in the art can appreciate. Preferably the backing 122 comprises a non-porous material so that moisture is retained at the interface. This promotes healthy grass at the edge of the bunker.

(17) The strip of backing 122 may be laterally divided into a plurality of adjacent sections, where each section is joined at only the first portion 128. This allows the edged interface 120 to be shaped to follow curves of the bunker as shown in FIG. 5. The artificial turf 124 comprises straight and curly yarn, and has a color to match natural turf stacked bunker edges.

(18) The strip of backing 122 may also be divided into the adjacent sections by a cut-out in the backing forming a triangular void 126 as shown in FIG. 6. The adjacent sections are joined together only at the first portion 128 and the second portion 130 of each respective section has a free end that can be positioned to match the curve of the bunker. As explained above, the second portion 130 of the edging interface 120 does not have any artificial turf and instead is configured to be secured by porous concrete between the golf course bunker and the grass edge 114 around the golf course bunker 100.

(19) In a particular aspect, the edging interface 120 is divided into the adjacent sections by the voids 126 in order for the strip 122 to be arranged in a curvilinear pattern while joined together only at the first portions 128 as shown in FIG. 7. The voids 122 may be triangular shaped or any suitable shape as those of ordinary skill in the art can appreciate. The triangular shaped voids 126 are desirable for inside curves 125 and perpendicular lateral cuts in the edging interface 120 are desirable for straight and outside curves 127.

(20) The edging interface 120 can be rolled up for shipping and storage as shown in FIG. 9. In addition, installation of the edging interface 120 is more efficient over prior methods that must be stacked like bricks or using parts of natural turf. Instead, the edging interface 120 of the present invention can be placed in position and unrolled saving on time and labor costs. A hole 132 may be in the second portion 130 of the backing and used to help restrain and secure the edging interface 120 by pouring concrete therethrough or using a peg, for example.

(21) An enlarged view of the backing 122 and the artificial turf 124 is shown in FIG. 10. In addition, a plurality of layers of the edging interface 120 can be stacked to form a built-up edge between the grass edge and the bunker.

(22) In another aspect a method of constructing an edging interface for a golf course bunker is disclosed. The method includes installing a porous concrete liner 110A for the golf course bunker 100 and forming a ledge 110B between a grass edge 114 of the golf course and the golf course bunker 100. The method also includes placing an edging interface 120 over the ledge 110B of the porous concrete liner, where the edging interface 120 comprises a strip of backing 122 divided longitudinally into a first portion 128 and a second portion 130. The strip of backing 122 is also divided laterally into a plurality of adjacent sections, where each adjacent section is joined together at the first portion 128. The method includes applying a porous concrete anchor layer 110C over the second portion 130 to secure the edging interface 120 in place. The method may also include stacking a plurality of the edging interface 120 to form a built-up edge between the grass edge and the golf course bunker.

(23) Many modifications and other embodiments will come to the mind of one skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is understood that the disclosure is not to be limited to the specific embodiments disclosed, and that modifications and embodiments are intended to be included within the scope of the appended claims.
