Description
- This invention relates generally to synthetic turf that appears realistic and more particularly to artificial turf fibrillating apparatus and methods thereof for improving the appearance, feel and playing characteristics of artificial grass turf to simulate natural grass turf.
- In the past, artificial grass turf has been made in a variety of ways. Typically artificial grass turf is formed from piles or strands coupled to a backing or base sheet to make a pile carpet. The piles are usually thin strands of plastic material colorized to appear like natural grass turf. The synthetic grass blades may comprise any suitable plastic that is sufficiently flexible, non-crimping and durable to withstand the demands that are placed on the intended use of the artificial grass turf. Examples of suitable plastics are various polypropylenes, nylons and polyesters.
- More recently, it has been recognized that currently available artificial grass turfs still appear synthetic because of the lack of randomness in the shape and appearance of the artificial grass blades forming the pile. Such currently available grass turfs are also too glossy and feel too smooth and greasy in comparison to natural grass blades. These properties of artificial grass turf originate from the chemical and mechanical properties of the polymers that make up artificial grass blades.
- There have been several attempts to improve on making artificial grass more natural in appearance. In one example Pettigrew, U.S. Pat. No. 5,951,780 suggested using a surface treatment apparatus comprising a rotating shaft and bristles mounted on the shaft for dislodging particulate matter form the artificial grass turf. Pettigrew, U.S. Pat. No. 5,951,780 disclosed the use of the apparatus for cleaning up artificial grass turf used in playing field areas such as tennis courts to freshen up the matted appearance of the artificial grass turf in addition to dislodging the particulate matter.
- In a second example disclosed by Prévost, U.S. Pat. No. 5,958,527 a process of laying synthetic grass includes a pile carpet having coarse granules inserted therein and splitting synthetic grass blades using a stiff wire brush. No details were provided regarding the nature of the wire brush or the effectiveness of the splitting process, since the main emphasis of Prévost, U.S. Pat. No. 5,958,527 was on providing for granules within the artificial grass turf.
- In a third example, Lemieux, U.S. Pat. No. 6,602,113 disclosed the use of sand-like particular blasting of the upper portion of artificial grass turf grass blades. The blasting is applied for a sufficient time and a sufficient pressure to shred the artificial grass blade upper end portions into fine slivers, which remain joined to their respective blades and become intertwined with adjacent slivers to form a dense mat upon the surface of a pile artificial grass turf carpet. Lemieux, U.S. Pat. No. 6,602,113 further disclosed that after sandblasting, the artificial grass blades may be sprayed with high pressure water or brushed to further separate intertwined artificial grass blade slivers.
- While Lemieux, U.S. Pat. No. 6,602,113 discloses a procedure that provides a more realistic and useful artificial grass turf, the use of sandblasting equipment to achieve the result is beyond the scope of the average consumer. In addition, sandblasting usually requires fairly strenuous health consideration because of all the particulate matter that is used in the process.
- For the foregoing reasons, there is a need to provide artificial turf fibrillating apparatus and methods thereof. This invention provides artificial turf fibrillating apparatus that may be used by an average consumer or on a large scale without producing obnoxious particulates. The resulting artificial grass turf of this invention has the appearance, feel and playing characteristics of artificial grass turf which simulates natural grass turf.
- Accordingly, it is an object of this invention to provide improved artificial turf fibrillating apparatus.
- It is a still further object of this invention to provide improved artificial turf fibrillating apparatus that are easy to use and to maintain.
- It is a still further object of this invention to provide improved artificial grass turf using the artificial turf fibrillating apparatus of this invention.
- It is a yet further object of this invention to provide methods for improving the appearance of artificial grass turf using the artificial turf fibrillating apparatus of this invention.

Alternatively, the fibrillating members comprise a bolt having a head, a threaded portion of the bolt for receiving a nut to securely couple each one of the fibrillating members to a lower portion of the support member and the head is sized to couple to an upper portion of the support member to prevent each one of the fibrillating members from decoupling from the support member.
- The support member has a hole for receiving a shaft, a first end of the shaft coupled to the support member and a second end of the shaft coupled to the power source means for rotating the support member and the power source means provides sufficient torque to cause visible fibrillation of the plurality of broad artificial grass blades when the fibrillating member impacts the artificial grass turf.

FIG. 5 is an elevation view of a third example of an artificialturf fibrillating apparatus 20 for producing the fibrillatedartificial grass turf 14. The artificialturf fibrillating apparatus 20 is identically described as above in all respects except for details regarding each one of the fibrillatingmembers 28. Each one of thefibrillating members 28 comprises a portion of a partially threaded bolt having no head. Sufficient thread is provided on the fibrillatingmember 28 to permit coupling of afirst nut 30 and asecond nut 30 to the threaded portion of the fibrillatingmember 28. Although the fibrillatingmember 28 is shown to be cylindrical in shape (see FIGS. 3,4,5), it is understood that the unthreaded portion of the fibrillatingmember 28 may be any shape that results in fibrillation of broadartificial grass blades 12 producing fibrillatedartificial grass blades 16. The fibrillatingmember 28 is supported on the upper portion of thesupport member 22 by thefirst nut 30. Thesecond nut 30 securely couples the fibrillatingmember 28 to a lower portion of thesupport member 22. When any one of thefibrillating members 28 is worn, the worn fibrillatingmember 28 is easily replaced by unthreading thefirst nut 30 or thesecond nut 30. - The
shaft 24 is preferably coupled to apower source 26 such as an electric or a gas powered lawn mower, a WEEDWACKER® (SEARS, ROEBUCK AND CO. CORP., ILLINOIS), or a powered edge trimming tool that provides rotary motion. It is understood that anypower source 26 to which thesupport member 22 may be coupled by ashaft 24 is suitable. Thepower source 26 must provide sufficient torque to cause visible fibrillation of the broadartificial grass blades 12. It is understood that sufficient torque depends on the revolution rate, distance between thefibrillating members 28 and the force produced by thepower source 26. - The
support member 22 is preferably rigid. Suitable choices for the rigid material of thesupport member 22 are metals such as iron or steel alloys. Thefibrillating members 28 are preferably rigid. Suitable choices for the rigid material of thefibrillating members 28 are metals such as iron or steel alloys. It is understood that the choice of rigid material is not limited to iron or steel alloys, but rather that these are merely examples of possible material choices. Typically,steel fibrillating members 28 are replaced after treating several hundred square yards ofartificial grass turf 10. - The plane of rotation of the
support member 22 is less than at a right angle to the plane of the backing 18 of theartificial grass turf 10 during operation of the artificialturf fibrillating apparatus 20. More preferably the plane of rotation of thesupport member 22 is substantially an acute angle to the plane of the backing 18 of theartificial grass turf 10 during operation of the artificialturf fibrillating apparatus 20. Most preferably, the plane of rotation of thesupport member 22 is between 0° and 45° to the plane of the backing 18 of theartificial grass turf 10 during operation of the artificialturf fibrillating apparatus 20. - The
support member 22 can be of various lengths and widths. A preferable length of thesupport member 22 for use with lawn mowers is about 21 inches. The fibrillating portion of thefibrillating members 28 may also be of various lengths and widths. A preferable length for the fibrillating portion of thefibrillating members 28 is about 2 inches below the lower portion of thesupport member 22. - When the
support member 22 is coupled to a lawn mower, thesupport member 22 is readily coupled to the lawn mower in the same manner as a conventional mower blade, thereby requiring no special skills for an average consumer. The height of the lawn mower is readily adjustable, allowing different depths of fibrillation of the broadartificial grass blades 12 and adjusting for wear of thefibrillating members 28 by lowering the lawn mower settings. - The broad
artificial grass blades 12 are reduced in width to the fibrillatedartificial grass blades 16 having random widths less than about 0.15 inches. Preferably the widths of the fibrillatedartificial grass blades 16 have random widths of less than about 0.1 inches. - In summary, artificial turf fibrillating apparatus have been disclosed. Methods for providing fibrillated artificial grass turf derived from artificial grass turf have been disclosed. The apparatus comprise a rotating rigid support member having a plurality of removable fibrillating members coupled to the support member. The apparatus are coupled to a power source. A plurality of broad artificial grass blades of an artificial grass turf are impacted by the fibrillating members when the support member is rotated with sufficient torque to provide a fibrillated artificial grass turf comprising a plurality of fibrillated artificial grass blades of random width having the appearance, feel and playing characteristics of a real grass turf.
- While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention. For example, artificial grass turf comprising artificial rocks and/or artificial sand particles embedded in the backing of the artificial grass turf may be fibrillated to provide a more realistic fibrillated grass turf. A plurality of support members may be coupled to one another on a substantially central shaft to provide a plurality of fibrillating members, thereby increasing productivity rates. Alternatively, a plurality of support members may be coupled to one another on a plurality of shafts to provide a plurality of fibrillating members. Additionally, the fibrillating member may comprise a flexible material such as plastic, fiberglass or twine coupled to a member that may be coupled to the support member.
