Abstract
A putting practice apparatus (10) including an elongated generally rectangular framework member (20) that supports a putting surface unit (12) including a raised platform member (30) having a simulated grass surface (31) and a cup aperture (32) disposed proximate one end wherein, a ball return pipe (36) and branched ball return pipe segment (37) are operatively associated with the putting surface unit (12) and four screw jack members (40) are disposed adjacent the four corners of the framework member (20) to selectively provide uphill, downhill, right- and left-hand side hill orientations to the raised platform member (30).
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the field of putting practice devices in general and in particular to an angularly adjustable putting practice apparatus.




2. Description of Related Art




As can be seen by reference to the following U.S. Pat. Nos. 6,146,284; 5,863,256; 5,855,522; 5,445,381; and, 5,390,925, the prior art is replete with myriad and diverse putting practice devices.




While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical putting practice apparatus that is incrementally angularly adjustable to provide uphill, downhill and side hill dispositions of the golf hole relative to the golfer.




As most golfers are all too well aware, hardly any conventional golf course greens are perfectly flat which renders most putting practice devices relatively useless due to their inability to simulate actual putting conditions.




As a consequence of the foregoing situation, there has existed a longstanding need among golfers for a new and improved angularly adjustable putting practice apparatus that can at least approximate conditions that the golfer would encounter on a real golf course, and the provision of such an apparatus is the stated objective of the present invention.




BRIEF SUMMARY OF THE INVENTION




Briefly stated, the putting practice apparatus that forms the basis of the present invention comprises in general a framework unit, a putting surface unit and an adjustment unit that can incrementally adjust the angular orientation of the framework unit relative to a horizontal support surface.




As will be explained in greater detail further on in the specification, the framework unit includes an elongated rectangular framework member which surrounds and supports a raised putting surface platform member having a cup aperture and a branched ball return pipe member which guides a golf ball entering the cup aperture of the platform member or landing on a front floor panel segment of the framework member to a rear floor panel segment of the framework member.




In addition, the adjustment unit includes four screw jack members disposed adjacent to the four corners of the framework member wherein, the screw jack members are independently actuatable to give the platform member a variable angular orientation ranging between an uphill lie, a downhill lie, a right-handed or left-handed side hill lie so that the golfer can practice putts corresponding to actual putting conditions on a golf course.











BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS




These and other attributes of the invention will become more clear upon a thorough study of the following description of the best mode for carrying out the invention, particularly when reviewed in conjunction with the drawings, wherein:





FIG. 1

is a perspective view of the putting practice apparatus in use;





FIG. 2

is a side cross-sectional elevation view of the apparatus;





FIG. 3

is a bottom plan view of the apparatus; and,





FIG. 4

is an isolated cross-sectional detail view of the distal end of the putting practice apparatus.











DETAILED DESCRIPTION OF THE INVENTION




As can be seen by reference to the drawings, and in particular to

FIG. 1

, the putting practice apparatus that forms the basis of the present invention is designated generally by the reference number


10


. The apparatus


10


comprises in general a framework unit


11


, a putting surface unit


12


, and an adjustment unit


13


. These units will now be described in seriatim fashion.




As shown in

FIGS. 1 through 3

, the framework unit comprises an elongated rectangular framework member


20


having elongated opposed sidewalls


21




22


that are connected to one another by a front wall


23


and a rear wall


24


wherein, the front wall


23


is provided with a contoured floor panel segment


25


and the rear wall


24


is provided with a generally flat floor panel segment


26


and the floor panel segments


25




26


are further supported by cross-braces


27


and


28


which extend between the opposed sidewalls


21




22


.




In addition, as shown in

FIGS. 3 and 4

, each of the cross-braces


27


and


28


is provided with a pair of roller wheel assemblies


29


disposed at the opposite ends of each cross-brace


27


and


28


such that the wheel assemblies are spaced inwardly from the front


23


and rear


24


walls of the framework member


20


.




Turning now to

FIGS. 2 through 4

, it can be seen that the putting surface unit


12


comprises an elongated rectangular platform member


30


provided with a simulated grass surface


31


and having a regulation sized cup aperture


32


provided proximate the distal end of the platform member


30


wherein, the distal and proximal ends of the platform member


30


are provided with angled front


33


support and rear


34


panels each provided with a ball return aperture


35


that is in open communication with an elongated ball return pipe


36


extending between the apertures


35


and further provided with a branched pipe segment


37


that is connected to the cup aperture


32


in the platform member


30


.




In addition, as can best be seen by reference to

FIGS. 3 and 4

, the platform member


30


is further supported in an elevated position relative to the front


25


and rear


26


floor panel segments and spaced from the front


23


and rear


24


walls of the framework member


20


by a plurality of discrete shelf elements


38


which extend outwardly from the opposed sidewalls


21




22


to support the underside of the platform member


30


.




As shown in

FIGS. 2 through 4

, the adjustment unit


13


comprises a plurality of screw jack members


40


disposed at the four corners of the framework member


20


wherein, the screw jack members


40


have an enlarged head


41


adapted to be engaged by the socket head


51


of a long stemmed socket wrench element


50


to vary the individual effective height of each screw jack member


40


relative to the framework member


20


such that the putting platform member


30


can be disposed in an uphill, downhill, as well as, a right or left-handed breaking side hill disposition to present different challenges to the golfer.




Turning now in particular to

FIGS. 2 and 3

, it can be appreciated that the front floor panel segment


25


is raised above the height of the rear floor panel segment


26


and contoured such that any golf ball


60


landing on the contoured front floor panel segment


25


will be directed by gravity into the ball return pipe


36


for delivery to the rear floor panel segment


26


in a well recognized manner.




Furthermore, as can be appreciated by reference to

FIGS. 2 and 4

, the screw jack members


40


may be retracted such that the wheel assemblies


29


can be employed to move the apparatus


10


to a desired location.




Although only an exemplary embodiment of the invention has been described in detail above, those skilled in the art will readily appreciate that many modifications are possible without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims.




Having thereby described the subject matter of the present invention, it should be apparent that many substitutions, modifications, and variations of the invention are possible in light of the above teachings. It is therefore to be understood that the invention as taught and described herein; is only to be limited to the extent of the breadth and scope of the appended claims.
