ABSTRACT:
FIELD OF THE INVENTION
This invention relates to miniature golf putting greens. More particularly, it refers to a portable sectional golf putting green wherein sections are held together by cam locking fasteners.
BACKGROUND OF THE INVENTION
It is common in the miniature golf hole courses found in amusement facilities to construct a cement foundation base covered with outdoor carpeting. Obviously such courses are not portable and cannot be disassembled and moved to a different location. Recently, miniature golf hole systems have been constructed from an expanded polystyrene foam base as shown in U.S. Pat. No. 5,916,034. The polystyrene base is covered with a porous rubberized material and this rubberized material is covered with outdoor carpeting. This type of system facilitates drainage of the carpet surface but is so massive in structure as to foreclose its easy movement to a substitute location. Backyard golf enthusiasts wish to have a single golf green to which they can chip and on which they can practice putting. However, multiple uses for limited backyard space forecloses the construction of a permanent putting green as shown in U.S. Pat. No. 5,916,034. Homeowners wish to be able to disassemble the putting greens and store them when not in use so backyard areas can be used for alternate purposes. Therefore, a need arises for a portable golf course green.
SUMMARY OF THE INVENTION
I have invented a portable golf course green having multiple sections that can be readily locked together and covered with outdoor carpeting to create a chipping and putting green. The portable putting green can be easily disassembled and stored when not in use by rolling up the outdoor carpet and detaching the sectional pieces. Each sectional piece includes a polymeric bottom ribbed layer that is in contact with a substrate. Glued or otherwise attached to the bottom ribbed section is a top sheet of ABS plastic. The outdoor carpet is cut and rolled over the top sheet to form the putting surface. A hole is formed in the carpet, top sheet, and the ribbed section to receive a cup adapted to accept a putted golf ball. Cammed locking fasteners are installed on a side surface of each mating section to engage a corresponding section. An allen wrench operates the fastener.
