Description
- The present application claims priority to U.S. Provisional Application No. 60/700,678, filed Jul. 19, 2005, which is incorporated herein by reference.
- The present invention is directed to the field of putting surfaces and, more particularly, to a method and apparatus for a flexible, expandable putting green that is versatile and portable.
- Portable practice putting greens are widely used in many offices and homes throughout the world. Although such putting greens can be as simple as a carpet and a sideways glass, typical practice putting greens include a unitary putting surface laid on the ground with a cup at one end to which the golfer directs his putting shots. To improve portability of practice putting greens, rigid modular panels have been developed that may be connected together with various attachment mechanisms to form an integrated putting surface. (See, for example, U.S. Pat. Nos. 6,302,803, 6,669,572, 6,672,970 and 6,672,971 all to Barlow, which are all incorporated herein by reference). In other areas, foam pads have been developed that are capable of attachment to one another by interlocking teeth. (See, for example, U.S. Pat. No. 5,212,842 to Glydon, U.S. Pat. No. 6,588,167 to Chang, U.S. Pat. No. 6,761,563 to Lin, and D370,818 to D'Alessio, which are all incorporated herein by reference).
- Accordingly, there is a need for a practice putting green with an enhanced design that provides for versatile expandability and improved portability.
- An expandable putting green including interlocking panels. In various aspects of the invention, the interlocking panels are flexible pads or mats having a foam backing underlayer covered by a simulated grass surface overlayer. The interlocking panels provide flexibility in design to allow a user to construct a putting surface of any desired size or shape. At least one of the panels includes a removable portion that forms a hole in the panel into which a cup may be inserted such that it is recessed in the putting surface to receive a golf ball. In various embodiments, multiple panels may be compiled into a starter kit including materials for a basic putting green and expansion kits to provide unlimited expansion possibilities.

In one embodiment shown inFIG. 1A , the Expand-a-Green™ (trademarked by Dennco, Inc.) includes a starter kit with tenmodular interlocking panels 2, two regulation size cups 4 and twoflagsticks 6. Aflagstick 6 may be inserted and/or removed from a cup 4. The schematic illustrations ofFIGS. 1B and 2A show possible modular panellayouts including panels 2 without removable portions andpanels 2 withremovable portions 8 for the recessed cups 4. Further, thepanels 2 are connectable to one another by interlockingteeth 12. Most of the interlockingteeth 12 resemble a “dove-tail”type connection 14; however, certain of theteeth 12 may be differently configured, e.g., 16, to aid in orientation of the differentshaped mats 18 when thepanels 2 are connected to one another. A portion of the attachment mechanism of thepanels 2 including both the dovetailtype interlocking teeth 14 and the differently configuredinterlocking teeth 16 are illustrated with a dotted line inFIGS. 1B and 2A . The configuration as described provides for ease of shipping of multiple interlocking panels which may be stacked and easily transported in a 20 inch by 20 inch by 5 inch container 20 (seeFIG. 1C ).FIG. 2B is a side view showing the depth or thickness of amodular panel 2 according to one embodiment of the invention. - The expandable putting green, comprising at least two interlocked panels, is flexible, wherein the interlocked or individual panels may be bent, squeezed, and/or twisted in any direction. The panels may be constructed from material possessing elastic qualities, or of material that allows the panels to be compressed, condensed, and/or folded. The interlocked panels or assembled green retains flexibility while two or more of the panels are interlocked. In still other embodiments, the flexible, expandable putting green (i.e., at least two assembled, interlocking panels) takes and holds its shape without the need for any rigid platforms, molding, or backing.
- In various aspects, the flexibility of the present invention provides a soft, comfortable surface to practice for the user. Furthermore, the flexible surface provides more “give” than a rigid surface or platform, and better simulates a real golf playing or putting surface.
- It is will be apparent to those of ordinary skill in the art that there are a variety of ways to removably interlock the panels described in this application. By way of example and not by limitation, the panels may also be removably interlocked by any one or a combination of Velcro, hooks, tacks, glues, latches, or tongue and groove mechanisms.

Theremovable portions 8 and/or cup 4 may have a diameter of approximately 1-10 inches, and preferably approximately 4-5 inches. Theremovable portions 8 and/or cup 4 may have a diameter that is the same, slightly smaller, or slightly larger than a regulation golf hole size of approximately 4.250 inches. - In still other embodiments, the flexibility of the
panels 2 allows for the introduction of various shapes, sizes and textures underneath eachpanel 2. The introduction of an object under apanel 2 can simulate a real golf course or grass lawn for playing, including “breaks.” Furthermore, the flexibility of thepanels 2 allows a user to lay the green over a sloped or undulating surface (e.g., driveway or lawn) and the green can either take on the undulating shape of the surface on which it lies, or one can introduce objects under thepanels 2 to adjust for the slope or undulating surface. In yet another embodiment, at least one or more of thepanels 2 are reversible, and can be used interlocked with the panel lying on its face or back. In still other embodiments, thepanels 2 or green can be laid on or abut up against another surface to further simulate golf play. Some other surfaces include, but are not limited to, grass, sand, gravel, pavement, artificial turf, and any type of body of water. - In various embodiments, the expandable putting green of the present invention may be manufactured by die cutting sheets or rolls of
panel 2 material into the final desired shape of the green. An entire 10-piece starter set may be cut in a single stroke from a single cutting die, minimizing time and expense of manufacture. Alternatively, individual cutting dies are created for different shaped panels 2 (e.g., a different cutting die for expansion pieces (3) and (13)). In other embodiments,panels 2 made from different dies and/or different factories can be used interchangeably. In one aspect, thepanel 2 material comprises a flexible backing. In another aspect, the flexible backing is laminated onto the panel material. For example, flame lamination may be used to obtain waterproof lamination without the use of adhesives. -
