## Title
Golf mat

## Abstract

A golfing platform includes a standing region, for a user to stand to make their golf swing, and a striking zone, where a golf ball may be placed for striking by a golf club. The striking zone may be configured to replicate the feel of real turf, but where the artificial turf covering is not taken up as divots during a golf club swing. The striking zone can include a striking zone insert which may be formed from a hollow region surrounded by a flexible tubular material and encased with a covering material. The striking zone insert may have a height substantially the same as the height of the standing platform. A matting insert material may surround the striking zone to make the entire golf platform (the standing platform, the matting insert material and the striking zone insert) of uniform height, thereby mimicking a typical golf swing from the ground.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to golf accessories, and more particularly to a golf mat that replicates the feel of natural turf without having to replace divots when making practice swings.
2. Description of Prior Art and Related Information
During a conventional golf swing, the golfer lines the club up with a golf ball which lies on a tee or a grass surface. During the swing motion, the golf club generally, and preferably, impacts the ball slightly below the ball's mid-height lateral surface to create the desired amount of vertical trajectory. To achieve the desired outcome when striking a golf ball on a grass surface, the golf club head must travel through the uppermost part of the grass surface during the follow through. Thus, upon impact, it is common for divots, which are small pockets of grass material, to be removed during a golf swing due to the shear forces created internally within the turf itself. Divots are also important in that they provide feedback to the golfer, allow a complete follow through, and provide a more controlled and accurate resultant golf ball velocity and trajectory.
Natural grass surfaces have the ability to absorb the impact of the golf club during the golf club swing due mostly in part to the underlying compressibility and impact absorbing properties of the soil substructure. As such, the golfer generally does not feel the golf club head hit the grass surface and an optimal amount of the golf club's kinetic energy is imparted to the golf ball.
In order to perfect a golf swing and resultant ball trajectory, a golfer must repetitively practice the golf swing motions and the stance during the swing. As such, it is desirable for the golfer to repeatedly practice this swinging motion in a designated area. However, as explained above, with the inherent divot creation during a normal golf swing, natural grass surfaces are not practical for a golf swing practice location due to the inevitable numerous divots created, which would subsequently render the golf practice area useless within a very short period of time.
Driving ranges enable golfers to practice their golf swings using their woods and their irons. A typical driving range may be 350 to 400 yards in length, or longer, space permitting, and of sufficient width to accommodate a number of golfers at the same time. Typically, each golfer is allotted a predetermined amount of practice space within which he or she can safely swing their club to hit a golf ball down the driving range. The golfer may hit their ball from a wooden or plastic tee or from the surface of the practice space. When the golfer uses a tee, the golfer's swing should be and usually is identical to that which the golfer uses during normal play. However, when the golfer has not used a tee and has hit a ball from the surface of a practice space, the golfer usually has been required to adjust his or her swing to accommodate the conditions of the surface of the practice space.
The nature of the surface of the practice space can vary widely at any given driving range and from driving range to driving range. For example, the surface may comprise grass covered turf which is substantially identical to the conditions which the golfer would normally encounter on a conventional golf course fairway. Under such conditions, the golfer can and normally would utilize his or her normal swing which, when using an iron and sometimes when using a wood, requires that the club head be driven downwardly and “through” the ball resulting in the making of a divot at the apex of the swing. Unfortunately, such ideal conditions are not found at many driving ranges.
There has thus been a long-standing need within the golfing art to replicate the feel and feedback of natural grass surfaces for golf practice locations. Currently, artificial grass surfaces are utilized mainly for driving ranges. Artificial grass surfaces are generally preferred over natural grass surfaces for golf practice swinging due to the fact that artificial grass has greater longevity, is not prone to naturally occurring divots, is generally more customizable, and is less costly to maintain.
However, a major problem with creating a consistent and practical artificial grass surface is to create a natural feel to the synthetic grass surface and underlying core substructure. For example, some conventional golf practice artificial grass surfaces consist of a polymer based artificial grass leaf material overlaid on a hardened surface, such as wood, concrete or the like. A major limitation of such an artificial golf practice swing surface is the lack of realistic replication of the underlying soil substructure or turf.
When the golf club hits the artificial grass surface during a normal golf swing, and since the underlying surface does not have adequate compressive abilities or impact absorbing properties, the swing path of the golf club is redirected to a plane parallel to the grass surface thereby not allowing a follow through consistent with that experienced on natural turf wherein a divot is taken. Furthermore, when the golf club hits the hardened underlying surface, more often than not, the impact by the golf club creates undesirable and potentially dangerous shocks and vibrations to the golfer, thus possibly physically harming the golfer as well as damaging the golf club itself.
Accordingly, a need exists to improve golf practice mats so that they replicate the feel of natural turf, without the disadvantages thereof.

The invention and its various embodiments can now be better understood by turning to the following detailed description wherein illustrated embodiments are described. It is to be expressly understood that the illustrated embodiments are set forth as examples and not by way of limitations on the invention as ultimately defined in the claims.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS AND BEST MODE OF INVENTION
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, the present invention provides a golfing platform including a standing region, for a user to stand to make their golf swing, and a striking zone, where a golf ball may be placed for striking by a golf club. The striking zone may be configured to replicate the feel of real turf, but where the artificial turf covering is not taken up as divots during a golf club swing. The striking zone can include a striking zone insert which may be formed from a hollow region surrounded by a flexible tubular material and encased with a covering material. The striking zone insert may have a height substantially the same as the height of the standing platform. A matting insert material may surround the striking zone to make the entire golf platform (the standing platform, the matting insert material and the striking zone insert) of uniform height, thereby mimicking a typical golf swing from the ground.
Referring now to FIG. 1, a golf mat 10 includes a standing area 12 and a striking area 16. The striking area 16 includes a striking area cutout 14. The striking area cutout 14 is typically formed as an elongated circle, oval, egg shape or the like, there the major axis of the striking area cutout 14 aligns with a direction of swing of a golf club during use of the golf mat 10, as described below.
The standing area 12 is typically formed at a height raised from the striking area 16. Typically, the standing area 12 is from about 0.5 inch to about 2 inches, usually about 0.75 to 1 inch, higher than the striking area 16. While the figure shows the areas formed as rectangular areas, various shapes and sizes are contemplated within the scope of the present invention.
As shown in FIG. 2, the striking area can include a plurality of mounting holes. Striking zone insert mounting holes 28 may be disposed about the periphery of the striking area cutout 14. While the striking zone insert mounting holes 28 are shown forming a rectangular shape, they may be disposed in various configurations about the striking zone cutout 14. Matting material mounting holes 30 may be formed at front and rear ends of the striking area 16.
Referring to FIGS. 4-6, a striking zone insert 18 may be disposed into the striking zone cutout 14. As shown in FIG. 13, the striking zone insert 18 may be made from two sheets 18A, 18B of flexible material, such as fabric, rubber, flexible polymeric material, or combinations thereof. For example, in one embodiment, an upper one of the two sheets can include both a fabric layer and a rubber layer, for example. Stitching 22 or other adhering mechanisms may be used to join the two sheets 18A, 18B together. The stitching 22 may have a size and shape generally the same as the size and shape of the striking zone cutout 14.
A closure, such as a zipper 20, may be disposed on a bottom side of the striking zone insert 18. The zipper 20 may permit access to an interior of the striking zone insert 18, between the two sheets 18A, 18B. A flexible tubular material, such as an inner tube 24 may be disposed inside the striking zone insert 18, extending about the perimeter as shown in FIG. 5, which shows the inner tube 24 disposed outside of the striking zone insert 18. The inner tube 24 may form a hollow region encased by the two sheets 18A, 18B of the striking zone insert 18. The inner tube 24 may include an air valve 26 for inflating the inner tube 24. In some embodiments, a hollow or solid flexible member may be used in place of the inner tube 24. The inner tube 24 may extend the height of the striking zone insert 18 to be substantially the same height as the standing area 12.
Straps 38 (see FIG. 8) may extend inside the striking zone insert 18 to secure the inner tube 24 about the inner perimeter of the stitching 22. The straps 38 may be disposed on the sides of the striking zone insert 18, as shown in the Figures, or may be disposed at various locations about the striking zone insert 18. In some embodiments, the straps 38 may be excluded and the structural integrity of the inner tube 24 may keep the inner tube 24 at the desired location inside the striking zone insert 18.
Referring now to FIGS. 5, 7 and 8, mounting brackets 36 may be disposed about the outer perimeter of the striking zone insert 18. The mounting brackets 36 may align with the striking zone insert mounting holes 28 (see FIG. 2) and a bolt 34 may extend through the mounting brackets 36, through the striking zone insert mounting holes 28, and may be secured with a nut, 32, such as a T-nut, on a back side of the golf mat 10. The mounting brackets 36 may be formed from various materials and may be made in various shapes and sizes. Typically, the mounting brackets 36 are formed form a rigid, flat material, such as plastic, metal, wood, or the like. As shown in FIG. 8, typically, the mounting brackets 36 may have a height less than the height of the striking zone insert 18 when the inner tube 24 is disposed therein.
Referring to FIGS. 9 and 10, a matting material 42 may be placed over the striking area 16 and around the raised portion (defined as the portion of the striking area insert 18 inside of the stitching 22) of the striking area insert 18. An underside of the matting material 42, as shown in FIG. 10, may include channels 46 for receiving the mounting brackets 36 therein. The matting material 42 may have a thickness to create a height of the striking zone 16 that is generally the same height as the standing area 12. The matting material 42 can be formed from various materials, such as foam rubber, foam sponge material, rubber, plastic, wood, metal, or the like. Typically, the matting material 42 may be formed from a flexible, resilient material.
The matting material 42 can include a plurality of matting material holes 44 typically aligning with mattering material mounting holes 30 formed in the striking area 16 (see FIG. 2). As shown in FIG. 11, matting material mounting brackets 48 may be disposed on front and rear ends to secure the matting material 42 and turf 40 to the golf mat 10. In some embodiments, side matting material mounting brackets 50 may be included to better secure the matting material 42 and turf 40 to the golf mat 10.
To complete construction of the golf mat 10, turf 40 may be disposed over the standing area and over the striking zone 16 as shown in FIGS. 11 and 12. In some embodiments, a separate piece of turf 40, such as artificial turf, may be disposed over each zone 12, 16. This allows replacement of the turf 40 in the striking area 16 if needed from repeated use.
To use the golf mat 10, a user can disposed the golf mat 10 on a surface, such as on the ground, and place a golf ball above the hollow region of the striking zone insert 18. The matting material mounting brackets 48, 50 may be used to help align the golf ball. Generally, the golf ball 48, 50 may be disposed centrally between the brackets 48, 50. When the user swings a golf club, if the turf 40 is struck, the feedback/feel to the golfer is similar to that of natural grass. The combination of the inner tube 24 and the hollow striking zone insert 18 results in this replication of the feel of natural grass. However, by using the golf bat 10, a divot is not removed, but the turf 40 flexes with the striking zone insert and resiliently moves back to its original position after the swing, ready for the golfer's next swing.
The turf 40 can be chosen such that the golf ball may be placed directly on the turf 40, or may be suspended form the turf 40 on a tee.
The golf mat 10 may be used by an individual on any surface or multiple golf mats 10 may be aligned on a golf driving range, for example. In some embodiments, the standing area 12 of one golf mat 10 may be interconnected to a standing area 12 or a striking area 16 of an adjacent golf mat 10.
