Abstract
Novel devices and methods for covering underground sprinkler heads installed on golf courses and other sports fields are described. The invention, in certain aspects, comprises the use of mats for covering a sprinkler head lid and/or the above-ground or ground level portion of the underground casing for housing the sprinkler head assembly. The mats are formed of a shock absorbing material such that when a golf ball, for example, strikes the mat(s), the ball does not rebound away as severely compared to striking the rigid lid and/or above-ground casing portion directly (i.e. without the mat covering). Other embodiments including fabricating the sprinkler head lid and/or above-ground casing portions of the same shock-absorbing material.
Claims18
An underground lawn sprinkler assembly, said assembly comprising
- a. a projectable sprinkler head and a water conduit secured to said sprinkler head, said sprinkler head and conduit housed within a casing designed for underground installation, said casing having an underground portion for housing said sprinkler head and conduit, an open top end through which said sprinkler head may be raised and lowered when in operation, and a platform extending transversely from said open top end of said casing and positioned at ground level upon underground installation of said underground portion of said casing, said platform formed of a rigid material and having an upper surface;
- b. a lid secured to said sprinkler head, said lid formed of a rigid material and having an upper surface;
- c. a first mat secured to said upper surface of said lid, said mat formed of a uniformly solid layer of shock-absorbing material;
- and
- d. a second mat secured to said upper surface of said platform, said second mat having a centrally disposed opening configured to surround said open top end of said casing and within which said first mat is nested when said sprinkler head is in a lower position, wherein said second mat is formed of a uniformly solid layer of shock-absorbing material;
- and
- whereby when a ball strikes said first mat, the ball rebounds off said first mat to a lesser degree than if the ball had stricken the lid directly, and whereby when said ball strikes said second mat, the second mat causes the ball to rebound away from said second mat to a lesser degree than if the ball had stricken the platform directly.
A kit for attachment to an underground sprinkler system, said kit comprising:
- a first mat formed of a uniformly solid layer of shock absorbing material, said mat having an upper surface and a lower surface and wherein said lower surface is configured to attach to an upper surface of a projectable underground sprinkler head lid;
- and
- a second mat for attachment to a ground level or above-ground platform of an underground lawn sprinkler assembly casing, said second mat having a centrally disposed opening configured to surround a top opening of said casing and within which said first mat is nested when the sprinkler head lid is in a lowered position;
- wherein said second mat is formed of a uniformly solid shock-absorbing material;
- and
- whereby when a ball strikes said first mat, the first mat causes the ball to rebound away from said first mat to a lesser degree than if the ball had stricken the lid directly;
- and whereby when said ball strikes said second mat, the second mat causes the ball to rebound away from said second mat to a lesser degree than if the ball had stricken the platform directly.
A method for minimizing the severity of a ball's subsequent rebound from an underground sprinkler assembly upon striking said assembly, said method comprising:
- a. securing a first mat to a lid of a sprinkler head, wherein said lid is formed of a rigid material and said first mat is formed of a uniformly solid shock-absorbing material, such that when said ball strikes said first mat, the first mat causes the ball to rebound away from said first mat to a lesser degree than if the ball had stricken the lid directly;
- and
- b. securing a second mat to a ground level or above-ground platform integral with an underground casing for housing the sprinkler head, said second mat having a centrally disposed opening configured to surround a top opening of said casing and within which said first mat is nested when said sprinkler head is in a lowered position, wherein said platform is formed of a rigid material and said second mat is formed of a uniformly solid shock-absorbing material, such that when said ball strikes said second mat, the second mat causes the ball to rebound away from said second mat to a lesser degree than if the ball had stricken the platform directly.
