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.
