Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to a golf putting practice device and more particularly to such a practice device that fits into the floor duct of a forced air circulation system of a building and has a ball return mechanism.
2. Description of the Prior Art
A wide variety of golf putting practice devices are known in the prior art. Many such devices are designed to sit on the surface of a floor for putting practice and include a ball return mechanism that returns a ball back to the user after a successful putt. Although, such devices are useful for putting practice, they include a ramped sidewall that leads up to a simulated putting cup and, therefore, are not truly representative of putting on a golf green.
To overcome the deficiency of ramped golf practice devices, prior art practice devices have been developed that are adapted to fit into the floor duct of a forced air circulation system of a building such as those disclosed in U.S. Patents to Birchler, et al., U.S. Pat. No. 5,120,063; Ridge, U.S. Pat. No. 5,275,405 and Frotten, U.S. Pat. No. 5,620,375. The golf practice devices disclosed in these patents substantially eliminate the need for a ramped sidewall, but they all are formed from flat support plates that surround a ball receiving portion of the device, which flat plates provide an obstruction to such portion.
To lessen this problem, the Frotten patent discloses a golf practice device fabricated of a resilient material so that the device can be installed in a floor duct by bending the support plate for insertion underneath the carpet surrounding the duct. Although such configuration is an improvement in reducing obstruction to the ball receiving portion, the Frotten practice device cannot readily be moved from one vent to another and depending on the thickness of the carpet under which it is installed, the path to the cup is not completely level. Moreover, none of these in-floor devices include a ball return mechanism.
The present invention is designed to provide a golf putting practice device that overcomes the deficiencies of the foregoing prior art.
SUMMARY OF THE INVENTION
The present invention provides a golf putting practice device adapted to serve as a substitute for a floor vent that fits into a floor duct of a forced air circulation system of a building. The practice device includes a generally cup shaped ball receiving means having a bottom wall and two opposite sidewalls that are each attached to a flat support plate member extended perpendicularly outward from the sidewall upper portions. The bottom wall is associated with a ball return means for ejecting a golf ball from the receiving means.
The front wall of the ball receiving means further includes an upper notched portion that provides a golf ball open access to the receiving means and the plate members include a plurality of apertures for the passage of air therethrough. Preferably, the support plate members are generally equal in size so that the ball receiving means is located medially of the practice device. The support plate members and ball receiving means are sized so that the device generally conforms to the size of the floor duct in which it is to be installed. The support plate members further include a peripheral flange that overlies the circumference of the floor duct to support the device on the floor.
The foregoing and other advantages of the present invention will appear from the following description. In the description, reference is made to the accompanying drawings, which form a part hereof, and in which there is shown by illustration, and not of limitation, a specific form in which the invention may be embodied. Such embodiment does not represent the full scope of the invention, but rather the invention may be employed in a variety of embodiments, and reference is made to the claims herein for interpreting the breadth of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings and with reference first to
FIG. 1
, a golf putting practice device of the present invention is shown at
10
and is adapted to serve as a substitute for a floor vent that fits into a floor duct of a forced air circulation system of a building. The device
10
is preferably integrally formed with a ball receiving means
11
and a pair of generally flat support plate members
12
and
13
that are less than 2 millimeters thick.
Although the device
10
can be formed of plastic, such as in an injection molded process, it has been found that when made of flat sheet steel, the entire device can be manufactured by means of a stamp process that allows for manufacturing and production economies and advantages, and duplicates the production process of most standard floor vents. Of course, one skilled in the art can envision alternate materials of and processes for constructing the device
10
in accordance with the present invention based upon the teachings of the present disclosure.
The ball receiving means
11
is formed of a generally cup shaped configuration and includes front and rear walls
16
and
17
respectively, opposite sidewalls
18
and
19
, a bottom wall
20
and an open top
21
. The rear wall
16
has a forwardly extending arcuate upper portion
16
a
that extends over the open top
21
. As shown best in
FIG. 1
, the upper portion of the front wall
16
preferably is formed with a notched portion
22
for a purpose described below.
As can also be seen from
FIG. 2
, the receiving means bottom wall
20
is generally V-shaped to cause any golf ball putted into the means
11
to move to the center portion
27
of the wall
20
. Positioned in such center portion
27
is a ball return mechanism
28
for ejecting a golf ball out of the receiving means
11
.
The mechanism
28
is well known in the prior art and is available in various designs. Preferably, the mechanism
28
has a solenoid that is actuated by the depression of a trigger (not shown) that serves to sense when a ball is in a position to be ejected. The trigger can be operated either through visual or mechanical sensing of the presence of a ball. Upon actuation of the mechanism
28
by the trigger the ball is driven upwardly against the rear wall arcuate portion
16
a
, which directs the ball back toward the user.
Each of the support plates
12
and
13
is generally elongated and rectangular in shape, with a radius curve at each corner to prevent snagging or injury. The plates
12
and
13
extend outwardly from the upper portions of the sidewalls
18
and
19
respectively in perpendicular fashion and as shown by
FIG. 2
, the side plates
12
and
13
and the ball receiving means
11
are sized so that the device
10
fits within a floor duct of a forced air circulation system, as shown in FIG.
2
. In the preferred embodiment, the plates
12
and
13
are of the same length so that the ball receiving means is generally centered in the device
10
. However, it would be possible to vary the location of the receiving means by making the plates
12
and
13
of different lengths or to have only one of the support plates
12
and
13
, thereby placing the receiving means at one end of the device
10
. To hold the practice device
10
in place during operation, it may be preferably to tack it in place with 2-4 screws that will thread into the carpeting and pad, but not the underlying wood.
Preferably, the support plates
12
and
13
have a plurality of apertures
23
in parallel alignment with one another to provide for the passage of air out of the floor duct just as a standard duct vent would do. It may also be advantageous in terms of air flow to have similar type apertures in the bottom wall
20
of the ball receiving means
11
. The support plates
12
and
13
together with the ball receiving means
11
form a peripheral flange
25
about the device
10
for coacting with the circumference of the floor duct to maintain the device
10
in position seated in the duct opening. The flange
25
is formed with a beveled lip
26
that not only adds rigidity to such flange, but also provides an aesthetically pleasing “finished” look to the final product.
In operation of the device
10
, the user merely substitutes such device for an existing floor duct vent. In a passive manner, the device
10
functions sufficiently as would the replaced vent. When users wish to practice their putting skills, the recessed portion
22
of the front wall
16
serves as a putting target and a golf ball can roll directly into the ball receiving means
11
as a result of the notched portion
22
. The ball drops down to the bottom wall
20
of the receiving means
11
to engage the ball return mechanism
28
and is returned to the user as previously described.
Although the invention has been described with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited, since changes and modifications can be made therein which are within the full intended scope of this invention as defined by the appended claims. For example, the size of the ball receiving means can be increased or reduced in size as well as its notched front wall.
