Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a method and apparatus for storing a rake adjacent a sand trap of a golf course, and for selectively elevating the rake for use.
2. Related Art
Golf courses are typically provided with hazards, such as sand traps which are disposed about the greens and fairways of the golf course. During play, golf balls are often shot into a sand trap. In order to continue play, the player must enter the sand trap and shoot the golf ball out. Playing the ball from the sand trap leaves footprints in the sand, and creates a divot from the swing. These disturbances in the sand trap, if left unattended, can affect the roll of the next ball hit into the sand trap. As a courtesy to other players and/or under the rules of the game, the player must leave the sand trap in its original or undisturbed condition. For this purpose, one or more rakes typically are provided at each sand trap. The player can use the rake to smooth the sand in the sand trap.
Leaving rakes along side or in the sand traps results in numerous disadvantages. One disadvantage of leaving rakes along side a sand trap is the potential that a golf ball will strike the rake, and thus interfere with the shot. In addition, rakes left along side the sand trap are esthetically displeasing. In addition, such rakes may present a safety hazard to players who might inadvertently step on, or trip over, the rake. In addition, golf carts may inadvertently run over and break the rake. Furthermore, maintenance of the course is made more difficult as workers must move the rakes as they mow the course, and/or tractor-rake the sand trap. Another disadvantage of leaving rakes about the sand trap is that such rakes tend to migrate to one end or location of the sand trap. In addition, sunlight tends to destroy the fiberglass handle of rakes that are left out.
Various devices have been developed in an attempt to solve the above-mentioned problems. For example, U.S. Pat. No. 3,584,739 issued to Erichson discloses a container buried in the ground adjacent the sand trap with a hinged cover having an artificial turf surface. When not in use, the rake is stored in a horizontal orientation in the container. As further examples, U.S. Pat. No. 4,934,550 issued to Cash, and U.S. Pat. No. 5,042,812 issued to Tillman, both disclose a container buried under the ground surface. One disadvantage with these types of underground containers is the difficulty and inconvenience of retrieving the rake from the underground container. For example, the player may have to bend over, squat, or kneel to withdraw the rake from the container. Alternatively, the player may have to fish the rake out of the container by hooking part of the rake with a golf club and carefully raising the rake to a position in which it may be grasped.
SUMMARY OF THE INVENTION
It has been recognized that it would be advantageous to develop a system or method for storing a rake adjacent a sand trap of a golf course in such a way as to minimize any interference of the rake with play, speed up play, increase the esthetic appearance of the course, improve the safety of the players, and increase the efficiency of course maintenance. In addition, it has been recognized that it would be advantageous to develop a system or method for more easily retrieving the rake for use, and returning for storage.
The invention provides an underground rake storage system to store a rake adjacent a sand trap of a golf course, and advantageously to selectively elevate the rake for use. Preferably, the system utilized a rake with a typical configuration, or having a handle with proximal and distal ends, and a head disposed on the distal end. The system includes an elongated container to removably receive the rake therein, and which is disposed underground in a substantially vertical orientation. The container can include a main tube to receive the handle of the rake, and a tray disposed on the main tube to receive the head of the rake.
A lifting mechanism advantageously is disposed in the container to vertically elevate the rake. The lifting mechanism preferably elevates the head of the rake to a convenient grasping elevation, such as greater than approximately two feet. In addition, the lifting mechanism preferably moves the rake between a storage elevation, and a graspable elevation. In the storage elevation, the rake is disposed underground, and within the container. In the graspable elevation, the head is disposed out of the container, and above the ground.
In accordance with a more detailed aspect of the present invention, the system includes a counter-weight system to elevate the rake. The counter-weight system includes a receiver to receive the rake, and a counter-weight to elevate the receiver and rake. The receiver and counter-weight are movably disposed in the elongated container. A pulley can be disposed within the elongated container with a cord movably engaging the pulley, and attached to the receiver and the counter-weight.
In accordance with another more detailed aspect of the present invention, the system may include a latching mechanism for selectively retaining the rake in the container, and/or selectively activating the lifting mechanism. A bi-stable mechanism can be used which is engagable by the rake, and movable between a secure position, and an open position. In the secure position, the mechanism retains the rake within the container. In the open position, the mechanism allows the rake to be removed from the container. A pivot member can be pivotally coupled to the container, and engagable by the rake. A spring element can be disposed in the container and engagable by the pivot member to bias the pivot member between two positions.
A method for using the underground rake storage device, or for substantially concealing and selectively providing the rake adjacent the sand trap of the golf course, includes providing the elongated container underground adjacent the sand trap of the golf course in a substantially vertical orientation. The rake is selectively disposed in the container such that the rake is disposed underground in a substantially vertical orientation. The rake is selectively elevated out of the container in a substantially vertical direction, and substantially along a longitudinal axis of the rake.
Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
As illustrated in
FIGS. 1-4
, a rake storage system or device, indicated generally at
10
, is shown for storing a rake
14
adjacent a sand trap of a golf course. Preferably the system
10
is configured to store the rake
14
underground, or substantially under a surface
18
of the golf course. Golf courses and rakes are examples of fields that may benefit from the use of the rake storage system
10
. The rake
14
can have a typically configuration with an elongated handle
22
having a proximal end which is grasped by the user, and a head
26
formed on a distal end thereof for contacting and manipulating the sand. The rake
14
also has a longitudinal axis
30
, which generally is parallel and concentric with the handle
22
. The head
26
of the rake
14
can include a plurality of fingers along one edge, and a substantially continuous edge opposite the fingers, to rake the sand of the sand trap. It is of course understood that the rake
14
can have various different configurations.
The rake storage system or device
10
also includes an elongated container
34
configured to removably receive the rake
14
therein. The elongated container
34
is disposed underground, or under the surface
18
to conceal and/or position the container
34
and rake
14
. The container
34
includes an opening
38
through which the rake
14
passes into, and out of, the container
34
. The opening
38
preferably is located at the end or top of the elongated container
34
. The top of the container
34
or opening
38
preferably is located generally flush with the surface
18
. Thus, the rake
14
and container
34
are located underground to avoid interference with play, and improve aesthetics, while still remaining visible to facilitate locating the rake when needed.
Preferably the container
34
is configured to substantially match the shape or configuration of the rake
14
. The container
34
may include an elongated main tube
42
, and a trough or tray
46
disposed at the end of the main tube
42
. The main tube
42
is configured to receive the handle
22
of the rake
14
, while the tray
46
is configured to receive the head
26
. The opening
38
of the container
34
may be formed in the tray
46
.
The underground rake storage system or device
10
of the present invention advantageously includes a lifting mechanism to vertically elevate the rake
14
, or eject the rake
14
from the container
34
. Referring to
FIGS. 3 and 4
, the lifting mechanism advantageously can include a counter weight system
50
. A receiver or receiver tube
54
(
FIG. 2
) can be moveably disposed in the elongated container
34
or main tube
42
to receive the proximal end of the rake
14
therein. The receiver
42
can be operatively coupled to a counter weight
58
, which is also movably disposed in the elongated container
34
or main tube
42
. The counter weight
58
operates to elevate the receiver
54
(FIG.
2
), and thus the rake
14
. The receiver
54
(
FIG. 2
) and the counter weight
58
may be operatively coupled by a cord
62
. The cord
62
in turn may operatively engage a pulley
66
(best shown in
FIGS. 6
a
and
6
b
) disposed near the top of the elongated container
34
or at the top of the main tube
42
.
The receiver
54
and the counter weight
58
move or slide up and down within the main tube
42
. The cord and pulley
62
and
66
cause the receiver
54
and counter weight
58
to move in different directions, with the counter weight
58
moving in a downward direction as the receiver
54
moves in an upward direction, and vise versa.
The counter weight
58
preferably has a weight, which is greater than a combined weight of both the rake
14
and receiver
54
. Thus, the counter weight
58
tends to move in a downward direction under the force of gravity causing the receiver
54
with the rake
14
therein to move in an upward direction. Preferably, the counter weight
58
weighs only slightly more than both the rake
14
and receiver
54
to cause the receiver
54
and rake
14
to move upwardly in a slow, smooth motion. The slow motion or elevation of the rake
14
resists surprise or possible injury.
The lifting mechanism preferably is configured to elevate the rake
14
a significant distance to facilitate retrieval of the rake
14
from the container
34
. Preferably, the lifting mechanism elevates the head
26
of the rake
14
to a convenient, graspable elevation greater than approximately 2 feet, and more preferably greater than approximately 3 feet. It will be appreciated that the counter weight system
50
can be configured to elevate the rake
14
a desired distance, which is limited by the length of the cord
62
and the length of the counter weight
58
in the length of the main tube
42
. Thus, the length of the cord
62
and counter weight
58
can be selected such that the head
26
of the rake
14
is elevated to the desired elevation.
The lifting mechanism of the present invention provides a significant advantage over prior art rake storage systems in that the user is not required to bend over, kneel, or squat in order to retrieve the rake
14
from the container
34
. The lifting mechanism advantageously elevates the rake
14
to an elevation where the user may easily grasp the rake
14
, handle
22
or head
26
thereof
The lifting mechanism or counter weight system
50
moves or displaces the rake between a storage elevation, as shown in
FIGS. 1 and 3
, and a graspable elevation, as shown in
FIGS. 2
,
4
and
5
. In the storage elevation, the rake
14
is disposed under the surface
18
, and within the container
34
. At the graspable elevation, the head
26
of the rake
14
is disposed above the surface
18
, and out of the container
34
.
As stated above, the container
34
and rake
14
preferably are disposed in a vertical orientation. Therefore, the lifting mechanism or counter weight system
50
advantageously elevates the rake in a vertical direction, and along the longitudinal axis
30
of the rake
14
. Thus, the length of the rake
14
or the handle
22
itself is utilized in providing the rake
14
or head
26
thereof at a graspable elevation.
Although the container
34
and rake
14
are shown in a vertical orientation, it is of course understood that the rake
14
and container
34
can be disposed at a vertical incline, or at an angle with respect to the surface
18
. Such a configuration might be useful if the system
10
is disposed in an angled side of a sand trap or bunker.
An additional advantage of the counter weight system
50
is that the counter weight
58
and pulley
66
can be configured such that the rake
14
is slowly elevated out of the container. It will be appreciated that the counter weight system
50
causes the rake
14
to slowly elevate as the counter weight
58
slowly overcomes its inertia and builds momentum. The slow elevation of the rake
14
advantageously allows the user time to react and grasp the rake. In addition, such slow displacement resists surprises and/or injury.
The counter weight system
50
is one example of a lifting mechanism or a means for elevating the rake
14
. It is of course understood that other means for elevating the rake
14
may be used, including for example, an electric motor, hydraulics, a hydraulic actuator, a hydraulic motor, pneumatics, a pneumatic actuator, a pneumatic motor, a spring or other stored energy force, etc.
Referring again to
FIG. 2
, a guide tube
70
or guide track may be disposed in the main tube
42
. The receiver or receiver tube
54
can be slideably disposed in the guide tube
70
. The guide tube
70
prevents the receiver
54
and counter weight
58
from interfering with one another as they move.
The underground rake storage system or device
10
also advantageously includes a latching mechanism to selectively or releasably secure the rake
14
in the container
34
. The latching mechanism operates to prevent the lifting mechanism or counter weight system
50
from elevating the rake
14
out of the container
34
until desired. The latching mechanism may engage the rake
14
to prevent the rake from exiting the container
34
, or may engage the lifting mechanism or counter weight system
50
to prevent the lifting mechanism or counter weight system
50
from operating.
Referring to
FIGS. 6
a
through
6
c
, a bi-stable mechanism
80
is shown disposed in the tray
46
for engaging the rake
14
. The bi-stable mechanism
80
preferably has only two stable positions, and thus tends to move to either of the two stable positions. The two stable positions of the bi-stable mechanism
80
preferably correspond to a secure position, as shown in
FIG. 6
a
, and an open position as shown in
FIG. 6
b
. In the secure position, the mechanism
80
operates to retain the rake
14
within the container
34
. In the open position, the mechanism
80
allows the rake
14
to be removed from the container
34
, or allows the lifting mechanism to elevate the rake
14
.
The bi-stable mechanism can include a pivot member
84
pivotally coupled to the container
34
or tray
46
. The pivot member
84
can include an engagement portion or arm
88
, which is pivotal into the path of travel of the rake
14
, and engagable by the rake
14
or head
26
, as shown in
FIG. 6
b
. The engagement portion
88
may be forked to receive the handle
22
of the rake
14
therebetween, as shown in
FIG. 6
c
. The pivot member
84
also includes a bias portion or arm
92
, which engages a spring element
96
. The bias portion
92
engages the spring element
96
as the pivot member
84
pivots. The spring element
96
may be a leaf spring attached to the container
34
or tray
46
. The bias portion
92
of the pivot member
84
causes the spring element
96
to bend or deflect, as shown in dashed lines, as the bias portion
92
tracks along the spring element
96
. Thus, the spring element
96
tends to force the pivot member
84
towards either of the two positions, and provides resistance to movement of the pivot member
84
out of either of the two positions.
In use, placing the rake
14
in the container
34
causes the head
26
to contact the engaging portion
88
of the pivot member
84
, causing the pivot member
84
to pivot towards the closed position. Pivoting the pivot member
84
in the opposite direction allows the rake
14
to be withdrawn.
The bi-stable mechanism
80
is one example of a latching mechanism or retaining means for selectively and/or positively retaining the rake
14
within the container
34
, and/or for selectively activating the lifting mechanism. It is of course understood that other retaining means for selectively retaining the rake
14
in the container
34
can be used, including for example, a pressure release catch, magnetic latch, a two-way latch, etc. As stated above, the latching mechanism may be configured to engage the rake
14
itself, or can be configured to engage the lifting mechanism or counter weight system
50
. For example, a pressure release catch or magnetic latch may be disposed in the bottom of the container
34
or main tube
42
to engage and releasably secure the receiver
54
, and thus selectively prevent movement of the counter weight.
A lid
110
may be pivotally attached to the container
34
or tray
46
. The lid
110
may be sized and configured to wholly or partially cover the opening
38
of the tray
46
or container
34
. Preferably, the lid
110
extends over at least the main tube
42
to resist water and debris from entering the main tube
42
. The lid
110
may be secured to the pivot member
84
in order to operate in conjunction with the latching mechanism. Thus, the lid
110
is disposed over the rake
14
in the closed position to prevent withdrawal of the rake
14
from the container
34
, or to prevent the lifting mechanism from elevating the rake
14
.
The lid
110
has an upper surface that preferably is sized to have indicia thereon. The indicia can include information and/or advertising, including for example, the distance to the hole or green, the name of the course, the name or logo of a sponsor or advertiser, etc.
Referring to
FIG. 6
c
the tray
46
may be configured with a bottom wall which tapers downwardly away from the center of the tray
46
, and thus away from the opening in the main tube
42
, to prevent water and debris from being directed into the main tube
42
.
Referring to
FIG. 8
, another underground rake storage device, indicated generally at
150
is shown which is similar in many respects to the device described above. The device
150
includes a two-way latch or pressure release latch
154
, which is disposed in the bottom of the main tube
42
or in the bottom of the guide tube
70
. The two-way latch or pressure release latch
154
is engaged by the receiver
54
. Such catches or latches respond to unidirectional pressure to both engage and disengage. Thus, forcing the receiver
54
against the latch causes the latch to operate to engage the receiver, while again forcing the receiver
54
against the latch causes the latch to operate to disengage the receiver.
In use, the proximal end of the rake
14
can be inserted into the receiver
54
and pushed into the container
34
. When the rake
14
is received within the container
34
, the receiver
54
engages the two-way latch or pressure release latch
154
maintaining the rake
14
in the container
34
.
When it is desired to remove the rake, a downward force or pressure on the rake
14
presses or forces the receiver
54
against the two-way latch or pressure release latch
154
causing it to release the receiver
54
so that the lifting mechanism or counter weight system
50
can elevate the rake
14
.
In addition, the counter weight
58
can have a crescent shaped cross-section. Thus, the counter weight
58
can have an outer concaved surface shaped to match the main tube
42
, and an inner convex surface configured to match the guide tube
70
. Thus, the counter weight
58
is shaped to maximize the lateral space in the main tube
42
, thus reducing its length and maximizing lift.
Referring to
FIG. 9
, another underground rake storage device, indicated generally at
170
is shown which is similar in many respects to the devices described above. The device
170
includes a bi-stable mechanism
174
that has a similar operation, but different structural configuration, to the bi-stable mechanism
80
described above. The bi-stable mechanism
170
preferably has only two stable positions, and thus tends to move to either of the two stable positions. The two stable positions of the bi-stable mechanism
170
preferably correspond to a secure position, and an open position. In the secure position, the mechanism
170
operates to retain the rake
14
within the container
34
. In the open position, the mechanism
170
allows the rake
14
to be removed from the container
34
, or allows the lifting mechanism to elevate the rake
14
.
The bi-stable mechanism
170
is disposed in the tray
46
, and can include portions of the lid
110
. As described above, the bi-stable mechanism
170
can include a pivot member
84
pivotally coupled to the container
34
or tray
46
. The pivot member
84
can include an engagement portion or arm
88
, which is pivotal into the path of travel of the rake
14
, and engagable by the rake
14
or head
26
. The engagement portion
88
may be forked to receive the handle
22
of the rake
14
therebetween. The pivot member
84
also includes a bias portion or arm
92
, which engages a biasing mechanism
178
.
Referring to
FIGS. 10 and 11
, the biasing mechanism
178
can include a compression spring or coil spring
182
. The spring
182
can be contained in a housing
184
to protect the spring
182
, maintain the linear compression and expansion of the spring, and provide attachment of the spring. The housing can include first and second portions
186
and
188
which slide or move with respect to each other as the spring is compressed and expanded. The first portion
186
can be pivotally attached to the biasing portion or arm
92
of the pivot member
84
, while the second portion can be pivotally attached to the container
34
or tray
46
. The bias portion
92
of the pivot member
84
causes the spring
182
to compress as the pivoting member
84
pivots. Thus, the spring
182
or biasing mechanism
178
tends to force the pivot member
84
towards either of the two positions, and provides resistance to movement of the pivot member
84
out of either of the two positions.
The bi-stable mechanism
170
is another example of a latching mechanism or retaining means for selectively and/or positively retaining the rake
14
within the container
34
, and/or for selectively activating the lifting mechanism.
A method for using the systems or devices described above, and for substantially concealing and selectively providing the rake
14
adjacent the sand trap of the golf course, includes disposing the elongated container
34
underground, or under the surface
18
, adjacent the sand trap of the golf course. As stated above, the elongated container
34
preferably is vertically oriented, but may also be vertically inclined.
In addition, the rake
14
is selectively disposed in the container
34
, and thus the rake
14
also is disposed underground or under the surface
18
. Similarly, the rake
14
preferably is vertically oriented underground within the container, but may be vertically inclined.
The rake
14
may be disposed in the container
34
by inserting the handle
22
of the rake
14
through the opening
38
of the container
34
. The rake
14
is preferably inserted with the handle
22
first. The rake
14
may continue to be inserted to the container
34
until the handle
22
is substantially received in the main tube
42
, while the head of the rake
14
is received within the tray
46
.
In addition, the rake
14
may be inserted in the container
34
by placing the proximal end of the handle
22
into the receiver or receiver tube
54
. It will be appreciated that prior to receiving the rake
14
, the receiver or receiver tube
54
will be located near the upper end of the container or main tube
42
. For example, the counter weight
58
, which weighs more than the receiver or receiver tube
54
, will cause the counter weight
58
to move towards the bottom of the container
34
or main tube
42
, thus lifting the receiver or receiver tube
54
near the top.
Due to the lifting mechanism, such as the counter weight system
50
, it may be necessary to exert a downward force on the rake
14
in order to insert the rake
14
into the container
34
. Therefore, the rake
14
advantageously is prevented from merely dropping into the container, thus resisting damage. The users may exert a force on the rake
14
using their hands initially, and then complete the act of inserting the rake into the container using their foot or a golf club.
As the head
26
of the rake
14
is inserted into the tray
46
of the container
34
, the head
26
may engage the latching mechanism, such as the bi-stable mechanism
80
or
170
. The head
26
may contact the engagement portion
88
of the pivot member
84
as the head
26
enters the tray
46
causing the pivot member
84
to pivot, and causing the bias portion
92
to track or exert a force on the spring element
96
, or on the spring
182
or biasing mechanism
178
. As the head
26
continues the move into the tray
46
, and as the pivot member
84
continues to pivot, the spring element
96
or spring
182
causes the pivot member
84
to completely pivot into the closed or retaining position to maintain the rake
14
in the container
34
. For example, the lid
110
may be disposed over the tray
46
and rake
14
to prevent withdrawal of the rake
14
. In addition, the latch mechanism, such as the bi-stable mechanism
80
or
170
, prevents the lifting mechanism, such as the counter weight system
50
, from elevating the rake
14
out of the container
34
.
It is of course understood that other latching mechanisms may be used. For example, as the receiver or receiver tube
54
nears the bottom of the container
34
or main tube
42
it may engage a two-way latch or pressure sensitive latch
154
, which prevents the counter weight system
50
from elevating the rake
14
.
When needed, the rake
14
is selectively elevated out of the container
34
by a lifting mechanism, such as the counter weight system
50
. The rake
14
preferably is elevated in a substantially vertical direction, and substantially along its longitudinal axis
30
. Thus, the length and orientation of the rake
14
facilitates elevating the rake
14
to a convenient elevation. As stated above, the head
26
of the rake
14
preferably is elevated to a grasping elevation greater than 2 or 3 feet.
To elevate the rake
14
, it may be necessary to engage or disengage the latching mechanism. For example, the bi-stable mechanism
80
or
170
may be pivoted towards the open or release position. The user may pivot the pivot member
84
by pressing downwardly on the bias portion
92
with a golf club or foot, or by lifting upwardly on the lid
110
with the golf club. As the pivot member
84
is pivoted, the spring element
96
or spring
182
causes the pivot member
84
to pivot fully to the open position. In addition, the lid
110
is pivoted from above the rake
14
allowing the lifting mechanism, such as the counter weight system
50
, to elevate the rake
14
.
As stated above, the weight of the counter weight
58
preferably is slightly greater than the combined weight of the rake
14
and the receiver or receiver tube
54
. This slight mismatch in weight, and any frictional properties of the pulley
66
, result in the counter weight system
50
gradually elevating the rake
14
. Thus, the counter weight
58
gradually overcomes inertia and builds momentum, causing the rake
14
to gradually elevate from the container
34
. The gradual elevation of the rake
14
advantageously prevents any surprise or injury, which may result from a rapidly ejecting rake
14
.
It is of course understood that the rake
14
may be elevated with any type of lifting mechanism. In addition, the rake
14
may be selectively elevated in different ways depending on the latching mechanism. For example, if a two-way latch or pressure sensitive latch
154
is used, a downward force may be applied to the head
26
of the rake
14
causing the two-way latch or the pressure sensitive latch
154
to release.
The underground rake storage or device of the present invention provides significant advantages, including both substantially concealing the rake
14
, and selectively elevating the rake to a convenient grasping elevation. Disposing the rake
14
in container
34
underground reduces the risk that the rake
14
or container
34
will interfere with a golf ball or play of the game. Providing the container
34
flush with the surface
18
allows the location of the rake
14
to be easily ascertained, when needed. The underground rake storage system or device of the present invention has a low profile which maintains the esthetic appearance of the golf course, reduces the need for maintenance workers to move rakes during maintenance of the course, reduces the risk of broken rake handles, protects fiberglass rake handles from sunlight, and reduces the risk of injury.
In addition, elevating the rake
14
reduces the need for the golfer or user to bend over, squat, or kneel in order to retrieve the rake
14
. The movement of the rake
14
as it is elevated is graceful and sophisticated, adding to the esthetics of the golf course and the convenience of the players. In addition, the latching mechanism allows the player or user to selectively elevate the rake from a standing position.
It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims.
