BACKGROUND OF THE INVENTION
[0001] The present invention relates to a novel variable morphology putting green, specifically
designed for playing golf.
[0002] The field of the invention is that of the variable morphology putting greens simulating,
in an artificial manner, different experiences in putting operations on playing golf.
[0003] To that end are already known computer system controlled putting greens, which are
so controlled to modify their morphology or pattern, starting from mechanical systems
(usually cylinder and piston mechanisms), which prior systems have the disadvantage
that they are very complex and require a difficult and expensive maintenance.
SUMMARY OF THE INVENTION
[0004] Thus, the aim of the present invention is to provide such a variable morphology putting
green which is much more simple than like prior putting green systems, and which,
moreover, can be recovered in a very simple and easy manner in a failure event.
[0005] According to one aspect of the invention, the above aim, as well as yet other objects,
which will become more apparent hereinafter, are achieved by a putting green as claimed
in claim 1.
[0006] Preferred embodiments of the invention are defined in the remaining claims.
[0007] With respect to prior putting greens, the inventive putting green provides the advantage
that it is much more simple, owing to the provision of the plurality of inflatable
cushion elements, or cushion elements adapted to be filled by highly pressurized fluids.
[0008] Moreover, the arrangement of the filling means of the cushion elements outside of
the putting green body greatly facilitates the maintenance operations on said cushion
elements.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] The putting green according to the invention has been generally indicated by the
reference number 1 in figure 1.
[0011] Said putting green comprises a covering element 2 thereunder a plurality of cushion
elements 3, made of a flexible and strong material, are arranged.
[0012] Said cushion elements are filled by a pressurized fluid (such as air or a liquid
as water) which is supplied by a tube system 4 each tube of said system being controlled
by respective controlling valves 9 assembled on a delivery block 5 for delivering
the cushion element 3 filling-in fluid.
[0013] Moreover, each said valve 9 is operatively respectively coupled to a compressor 6
and a de-compressor 7, communicating through said valve 9, and accordingly with the
respective cushion element 3, through a respective duct 4.
[0014] In particular, the cushion element 3 filling-empting system is controlled by a PCL
8, designed for adjusting the opening/closing movements of the valves 9 of each said
cushion element, thereby easily modifying the morphology of the putting green 1 depending
on the player requirements.
[0015] As stated, the fluid medium for filling-in the individual cushion elements 3 can
comprise either a gas (preferably air) or a liquid (for example water).
[0016] Said cushion elements are made of a flexible material, adapted to switch from a fully
compressed position (an empty cushion condition) to a completely filled or full condition
(a full cushion condition) and vice versa.
[0017] Preferably, the putting green 1 comprises a plurality of putting green units 10,
each said unit being formed by a corresponding plurality of cushion elements 3 (figure
2).
[0018] According to a modified embodiment of the invention shown in figure 4, the putting
green 1 comprises a plurality of cushion elements forming a composite layered putting
green unit 11, in turn formed by a cushion element 12 of a large size, thereabove
one or more cushion element 3 unit 10 are arranged.
[0019] In the embodiment shown in figure 5, the putting green 1 comprises a covering element
2 thereaunder are arranged, in the following order: a base 13 including a plurality
of channel elements 14 for allowing tubes 4 to pass therethrough; large cushion elements
12 filled-in either by air or water; and top overlapped cushion element 3 layers,
in a full cushion element 3a and empty cushion element 3b status.
1. A variable morphology putting green, including a covering element and means for varying
a level or height of said covering element with respect to a base therefor, characterized in that said means comprise a plurality of cushion elements designed for operating between
a completely full condition and a completely empty condition, said cushion elements
being filled-in by a filling-in fluid.
2. A putting green according to claim 1, characterized in that said filling-in fluid comprises a gas, preferably air, or a liquid, preferably water.
3. A putting green according to claim 1, characterized in that said putting green comprises moreover a compressor and a de-compressor for filling-in/empting
each said cushion element by said filling-in fluid.
4. A putting green according to claim 3, characterized in that said putting green comprises moreover a valve system including a plurality of valves
each of which is associated to a fluid delivery block, each said valve being controlled
by a computer system controlling a selective filling-in/empting of said cushion elements
depending on a morphology or pattern desired therefor.
5. A putting green according to claim 1, characterized in that said cushion elements are assembled to provide a cushion element unit for controlling
said level or height of said covering element.
6. A putting green according to claim 2, characterized in that said cushion elements are so assembled as to provide a composite layered unit including
a large size cushion element thereabove one or more of said cushion element units
are arranged.
7. A putting green according to claim 1, characterized in that said base comprises a plurality of channels for holding corresponding ducts therein.
