Description

BACKGROUND

Various sports are modified based on the different skill levels of players and to accommodate different characteristics of the players. In tennis for example, the Prince® racquet is oversized and has a long body to help beginning tennis players more rapidly improve their tennis skills. Shorter skis are used by beginning skiers to develop greater skiing proficiency. Various sized softballs are used in recreational leagues to make the ball easier to hit and catch. In basketball, a women's basketball is smaller than a men's basketball because on average women's hands are smaller than men's hands. Similarly, various size soccer balls are used for different age groups.

Competitive golf is played by a strict set of rules, but recreational golf is often played with more relaxed rules determined by the group of players playing. Recreational players frequently take a “mulligan” which is a second shot or a “gimmie” which is a putt that is assumed to be close enough that the player will not miss. Such modifications can speed play in some situations and also make the game more enjoyable for the average player.

SUMMARY

A golf hole enlargement device enlarges the standard golf hole size on a golf course without altering the putting surface of the golf green and allows recreational players or beginners to have a faster, easier, and more enjoyable golfing experience by reducing the occurrence of missed putts. The device includes, but is not limited to, a collar and a flange. The collar includes a first surface extending from a first edge to a second edge, a second surface extending from a first edge to a second edge, and a bottom surface extending from a first edge to a second edge. The first surface slopes upwards from the first edge to the second edge and is configured to rest on a horizontal surface. The second surface slopes downwards from the first edge to the second edge and mounts to the first surface. The first edge of the bottom surface is mounted to the first edge of the first surface. The flange is mounted to the second edge of the bottom surface and the second edge of the second surface and forms an open ring in a center of the collar for positioning over a golf hole of a golf green.

Other principal features and advantages of the invention will become apparent to those skilled in the art upon review of the following drawings, the detailed description, and the appended claims.

DETAILED DESCRIPTION

With reference to FIG. 1, a perspective view of a golf hole 102 is shown on a golf putting surface 100. Golf putting surface 100 may be an indoor, outdoor, or portable putting surface. Golf putting surface 100 includes at least one golf hole 102 though some putting surfaces, such as a putting practice green, may include more than one golf hole.

With reference to FIG. 2, a top view of a golf hole enlargement device 200 on golf putting surface 100 is shown in accordance with an example embodiment. In use, golf hole enlargement device 200 is positioned over golf hole 102. In an example embodiment, golf hole enlargement device 200 includes a first surface 202 and a second surface 204 where the first surface 202 encircles second surface 204 forming a collar that encircles golf hole 102.

Golf hole enlargement device 200 may be formed as a single unit formed of a single material or assembled from multiple parts formed from the same or different materials and having the same or different characteristics such as hardness, rigidity, and/or color. Golf hole enlargement device 200 can be constructed of any material such as metal, wood, silicone, rubber, plastic, other polymers, or a combination of such materials. In an example embodiment, golf hole enlargement device 200 is formed of silicone, rubber, or plastic. In an example embodiment, golf hole enlargement device 200 is formed of silicone having a Durometer hardness greater than about 50 Shore A and less than about 60 Shore A. Golf hole enlargement device 200 may be formed using injection molding of one or more pieces. In an example embodiment, multiple pieces may be heat bonded together.

With reference to FIG. 3, golf ball 106 is putted into golf hole 102 on golf putting surface 100. A standard golf hole has a diameter D of approximately 4.25 inches at its opening cut in a surface of golf putting surface 100 though this is not intended to be limiting. In an example embodiment, golf hole 102 includes a cylindrical wall 300 cut into golf putting surface 100 and a bottom surface 302.

With reference to FIG. 4, a side, cut-away view of a golf hole enlargement device 200a on golf putting surface 100 is shown in accordance with a first example embodiment. With reference to FIG. 5, a side, cross sectional view of golf hole enlargement device 200a is shown in accordance with the first example embodiment. Golf hole enlargement device 200a may include a collar 400, a rim 402, and a flange 404.

Collar 400 may include first surface 202, second surface 204, and a bottom surface 410. First surface 202 extends from a first edge 408 to a second edge 406. Second surface 204 extends from a first edge to a second edge 405. First surface 202 mounts to second surface 204. In the example embodiment of FIGS. 4 and 5, the first edge of second surface 204 corresponds to second edge 406 of first surface 202. Bottom surface 410 extends from a first edge to a second edge 412. In the example embodiment of FIGS. 4 and 5, the first edge of bottom surface 410 corresponds to first edge 408 of first surface 202. Bottom surface 410 may have a flat or concave surface. In the example embodiment of FIGS. 4 and 5, first surface 202, second surface 204, bottom surface 410, rim 402, and flange 404 form surfaces of a solid object formed as a single unit of the same material though this is not intended to be limiting.

Flange 404 is mounted between second edge 412 of bottom surface 410 and second edge 405 of second surface 204 and forms an open ring in a center of collar 400 for positioning over golf hole 102. Rim 402 mounts to and extends from flange 404 in a direction towards bottom surface 302 of golf hole 102. The direction may be straight downwards in the direction of cylindrical wall 300 or may have an angle relative to cylindrical wall 300 and towards a center of bottom surface 302 of golf hole 102. In the example embodiment of FIGS. 4 and 5, rim 402 abuts cylindrical wall 300, and thus has an outside diameter of approximately 4.25 inches. In other embodiments, rim 402 may have a smaller or a greater outside diameter depending on diameter D of golf hole 102. In other embodiments, rim 402 has a diameter less than the diameter D of golf hole 102. In the example embodiment of FIGS. 4 and 5, rim 402 has a length of approximately 0.5 inches and a thickness of approximately 0.25 inches.

First edge 408 of first surface 202 forms a circle though other shapes may be used without limitation such as ellipses, squares, rectangles, polygons, etc. First edge 408 of first surface 202 may have a dimension measured from the center of flange 404 of between approximately ten inches and approximately twenty inches. First surface 202 slopes upwards from a horizontal plane defined by golf putting surface 100 (or any other horizontal surface) adjacent golf hole 102 and positioned below first edge 408 of first surface 202. In example embodiments, first surface 202 slopes upwards at an angle greater than approximately five degrees and less than approximately twenty degrees. In the example embodiment of FIGS. 4 and 5, first edge 408 of first surface 202 has a diameter of approximately ten inches, and first surface 202 has a length of approximately 2.5 inches and forms an angle of eight degrees relative to golf putting surface 100 (or any other horizontal surface).

The first edge of second surface 204 forms a circle though other shapes may be used without limitation such as ellipses, squares, rectangles, polygons, etc. The first edge of second surface 204 may have a dimension measured from the center of flange 404 of between approximately seven inches and approximately ten inches. Second surface 204 slopes downwards from a horizontal plane parallel to golf putting surface 100 (or any other horizontal surface) adjacent golf hole 102 and defined at first edge 408 of first surface 202. In example embodiments, second surface 204 slopes downwards at an angle greater than approximately five degrees and less than approximately twenty degrees. In the example embodiment of FIGS. 4 and 5, the first edge of second surface 204 has a diameter of approximately 7.5 inches, and second surface 204 has a length of approximately 3.25 inches and slopes downwards at an angle of approximately 5.5 degrees.
