A mounting plate for a furniture hinge includes a hinge plate pivotably connected to a hinge component, such as a hinge cup, on a pivot axis. At least one front support members depends from the front edge of the hinge plate and is spaced a predetermined radial distance from the pivot axis. The front support member depends a distance from the hinge plate that is less than, and preferably not greater than three-fourths, the predetermined radial distance between the front support member and the pivot axis. The mounting plate also includes at least one opposing rear support member depending from the rear edge of the hinge plate a distance that is at least as great as, and preferably, at least one and three-fourths times, the distance by which the front support member depends from the hinge plate. At least one fastener opening is formed in one or both of the hinge plate and the at least one rear support member, and the front and rear support members are adapted to confront opposing sides of a cabinet member on which the mounting plate is installed and cooperatively provide subjacent lateral support for the cabinet member when a fastener received through the fastener opening is inserted into the cabinet member.
Description
FIELD OF THE INVENTION
The present invention relates generally to furniture hinges, and more particularly, to a mounting plate for mounting a hinge on a furniture article, such as a desk of cabinet, which in turn supports a door on the furniture article.
BACKGROUND OF THE INVENTION
In the cabinetry industry, a typical construction feature, for example, in cabinets which are provided with doors, is a face frame on which the door is supported and hinged. The face frame members are affixed, for example, to an opening in the cabinet, and a pair of concealed hinges are affixed to an edge one of the face frame members and the door. Typically, the face frame member to which the hinges are affixed is made of a relatively strong material, such as hardwood, and has a thickness in the range, for example of about one-half inch up to about three-fourths inch. A customary mounting method of affixing the concealed hinge to the face frame member utilizes a hinge mounting plate which is positioned on an edge of the face frame member and fastened to the face frame member with one or more fasteners, such as fastening screws, inserted through one or more openings in the mounting plate and into, for example, one or more corresponding pre-drilled holes in the face frame member. Alternatively, the face frame may be omitted entirely, for example, in frameless cabinets, and the hinge plate may be affixed directly to an edge of a cabinet wall member in a substantially similar way.
The customary method of affixing concealed hinges works well, for example, on cabinet components made of relatively strong materials, such as hardwood. However, serious problems are encountered when attempts are made to employ the customary method of affixing concealed hinges, for example, to less expensive materials, which are not as strong as hardwood. One such material is a panel product manufactured from lignocellulosic fibers combined with a synthetic resin or other suitable binder, commonly known as medium density fiberboard (MDF). MDF panels thinner than one-half inch are typically used, for example, for siding, and most of the thicker MDF panels (one-half to three-fourths inch) have generally been used as core materials for furniture panels. In recent years, however, use of finished MDF panels, for example, in cabinetry has become common in the manufactured or mobile home industry.
Attempts to employ the customary method of affixing concealed hinges in cabinetry by the manufactured home or mobile home industry, where MDF is now in relatively common use has met with mixed results. Reasons for the lack of success in the manufactured home or mobile home industry include, for example, that when fasteners such as fastening screws are used at or near an edge of a MDF cabinet panel component, such as a face frame member, which ranges in thickness from about one-half inch to about five-eighths inch up to about three-fourths inch, the pre-drilling of a fastener hole in the panel and/or inserting the fastener in the fastener hole tends to cause the panel component to weaken or split, so that in any event there is little or no resistance to withdrawal of the fastener from the fastener hole. Thus, the fastener tends to pull out of the cabinet component under the weight of the door supported by the hinge.
SUMMARY OF THE INVENTION
It is a feature and advantage of the present invention to provide a furniture hinge for a mounting plate which is inexpensive to make, easy to use, and which enables use, for example, of concealed, edge-mounted type hinges on relatively weak cabinet components, such as MDF panels.
To achieve the stated and other features, advantages and objects of the present invention, an embodiment of the present invention provides a mounting plate for a furniture hinge which includes, for example, a hinge plate with front and rear opposing edges which is pivotably connected to a hinge component, such as a hinge cup, on a pivot axis or pivot pin. At least one front support member depends from the front edge of the hinge plate that is spaced a predetermined radial distance from the pivot axis. The distance by which the front support member depends from the hinge plate is determined by the predetermined radial distance between the front support member and the pivot axis on which the hinge plate is pivotably connected to the hinge component. In an embodiment of the invention, the front support member depends a distance from the hinge plate that less than the predetermined radial distance between the front support member and the pivot axis, and preferably a distance that is not greater than three-fourths of the predetermined radial distance between the front support member and the pivot axis. Alternatively, the at least one front support member comprises a pair of front support legs depending from the front edge of the hinge plate.
In addition, according to an embodiment of the invention, at least one opposing rear support member depends from the rear edge of the hinge plate a distance that is at least as great as the distance by which the front support member depends from the hinge plate, and preferably the rear support member depends from the rear edge of the hinge plate a distance that is at least one and three-fourths times the distance by which the front support member depends from the hinge plate. Further, at least one fastener opening is formed in either or both of the hinge plate and the at least one rear support member, and the front and rear support members are adapted to confront opposing sides of a cabinet member on which the mounting plate is installed and to cooperatively provide subjacent lateral support for the cabinet member when a fastener received through the fastener opening is inserted into the cabinet member.
In an alternate embodiment, the at least one opposing rear support member comprises a pair of rear support legs depending from the rear edge of the hinge plate with a fastener opening formed in each of the rear support legs. Further, the fastener opening formed in each of the rear support legs can be open to a distal edge of the respective support legs. Instead of, or in addition to, having fastener openings formed in the rear support legs, one or more fastener openings can be formed in the hinge plate, and the fastener opening or openings formed in the hinge plate can have an elongate shape.
In the foregoing embodiments, the hinge plate has a hinge arm formed on its front edge that is pivotably connected to the hinge component on the pivot axis via a hinge pin. However, an alternate embodiment includes a multiple adjustment aspect in which the hinge plate is connected to the hinge component via an intermediate member slideably connected to the hinge plate, and a hinge arm member is pivotably connected to the intermediate member via a pivot pin and also pivotably connected to the hinge component on the pivot axis via a hinge pin. In this aspect, the intermediate member is slideably connected to the hinge plate via a pair of L-shaped bent projections on the hinge plate that form a channel slideably receiving the intermediate member and an eccentric screw received through an elongate aperture formed in the intermediate member and into an aperture formed in the hinge plate. Thus, turning the cam screw causes the intermediate member and the hinge arm member connected to the intermediate member via the pivot pin to move relative to the hinge plate slideably in the channel formed between the L-shaped bent projections on the hinge plate.
Further, in the multiple adjustment aspect, the hinge arm member is pivotably connected to the intermediate member on a pivot axis via a pin fastened through the hinge arm member and the intermediate member and an adjustment screw received through apertures formed in the hinge arm member and in the intermediate member. Thus, turning the adjustment screw causes the hinge arm member to move relative to the intermediate member arcuately about the pivot pin connecting the hinge arm member to the intermediate member.
Additional objects, advantages and novel features of the present invention will be set forth in part in the description which follows, and in part with become more apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention.

DETAILED DESCRIPTION
Referring now in detail to an embodiment of the present invention, an example, of which is illustrated in the accompanying drawings,
FIG. 1
shows a perspective view of the hinge
2
for an embodiment of the present invention. The hinge
2
includes a hinge cup
4
which is mountable, for example, in a recess of a cabinet door and a hinge arm
6
, which is pivotably connected to the hinge cup
4
. The hinge arm
6
extends from a hinge plate
8
, which is mountable on a cabinet component, such as a face frame member. The hinge plate
8
is generally rectangular in shape with opposing front and rear edges
10
and
12
and opposing ends
14
and
16
. A first pair of opposing legs
18
and
20
depend from opposing front an rear edges
10
and
12
respectively at or near one of the opposing ends
14
, and a second pair of opposing legs
22
and
24
extend from front and rear opposing edges
10
and
12
respectively at or near the other of the opposing ends
16
.
FIG. 2
shows a perspective view of hinge
2
of
FIG. 1
mounted on a cabinet component, such as a face frame member
26
and a cabinet door
28
for an embodiment of the present invention.
FIG. 3
is a side view of the hinge plate
8
of hinge
2
mounted on the face frame member
26
for an embodiment of the present invention. As shown in
FIG. 1
, the hinge cup
4
is provided with openings
30
and
32
for receiving fasteners, such as fastening screws
34
and
36
, as shown in
FIG. 2
, for affixing the hinge cup to cabinet door
28
. The hinge plate
8
is provided with openings
38
and
40
for receiving fasteners, such as fastening screws
42
and
44
, as shown in
FIG. 2
, for affixing the hinge plate to the cabinet component, such as face frame member
26
. In addition, or as an alternative, the rear legs
20
and
24
of hinge plate
8
can each be provided with an opening for receiving a fastener, such as opening
25
formed in rear leg
24
, as shown in FIG.
1
.
In an embodiment of the invention, opposing front and rear legs
18
and
20
are each perpendicular to hinge plate
8
and parallel to one another, and opposing front and rear legs
22
and
24
are likewise each perpendicular to hinge plate
8
and parallel to one another. Further, opposing front and rear legs
18
and
20
are spaced apart from one another by a distance that is substantially equal to a thickness “T” of cabinet member
26
, as shown in
FIG. 3
, and front and rear opposing legs
22
and
24
are likewise spaced apart from one another by a distance that is likewise substantially equal to the thickness “T” of cabinet member
26
.
A reason for such parallel relationship and spacing of the respective pairs of front and rear opposing legs
18
,
20
and
22
,
24
is that when fastening screws
42
and
44
are inserted through openings
38
and
40
and, for example, into pre-drilled openings in an edge portion of cabinet member
26
, front and rear opposing legs
18
,
20
and front and rear opposing legs
22
,
24
, respectively, rest against the opposite surfaces of cabinet component
26
adjacent the edge portion in confronting relationship with the opposite surfaces and cooperate with one another to provide lateral subjacent support against splitting of the edge portion as fastening screws
42
and
44
are tightened.
It is self-apparent that when hinge plate
8
is installed on the cabinet member
26
, such as a face frame member, the front legs
18
and
22
overlap the outer face
50
of the face frame member by the length of the front legs as can be seen from FIG.
3
. The hinge cup
4
is installed in the back side of the cabinet door
28
as near as possible to the inside edge
29
of the cabinet door, and when the cabinet door is closed, the cabinet door
28
typically overlaps the face frame member
26
on the hinge side by about one-half inch and thus hides about one-half inch of the edge portion of the face frame member. Esthetically, it is preferable that the front legs
18
and
22
mounted on the edge portion of the face frame member
26
are not exposed to view when the cabinet door
28
is closed. Thus, in an embodiment of the present invention, in order to assure that the front legs
18
and
22
do not show when the cabinet door
28
is closed, the front legs
18
and
22
extend no further than absolutely necessary to provide lateral support, for example, to keep the MDF from splitting when the fasteners
42
,
44
are tightened. It has been found that for this purpose an optimum length for the front legs
18
and
22
is about one-fourth inch, and more particularly, the maximum length for the front legs
18
and
22
is five-sixteenths inch.
Further, when the cabinet door
28
is moved, for example, from an open to a closed position, the inside edge
29
of the door swings in an arc about a pivot axis
27
on a turn radius that must clear the front legs
18
and
22
in order to close. It has been found that in order to be able to freely open and close the cabinet door
28
for an embodiment of the present invention, the front legs
18
and
22
must depend from the hinge plate
8
a distance which is not greater than about three-fourths of the distance between the front faces of the front legs
18
and
22
and the pivot axis
27
on which the hinge arm
6
is pivoted in the hinge cup
4
. Typically, the distance between the front faces of the front legs
18
,
22
and the pivot axis
27
is approximately seven-sixteenths inch. Thus, the front legs
18
and
22
for an embodiment of the invention do not depend further than about five-sixteenths inch from the hinge plate
8
. At the same time, it has been found that such a distance is adequate to provide sufficient lateral support to avoid splitting the edge portion of the MDF cabinet component
26
when fasteners
42
,
44
are tightened.
In order to cooperatively provide the support necessary to prevent such splitting of the edge portion of cabinet component
26
, the rear legs
20
and
24
, respectively, for an embodiment of the invention must depend a distance from hinge plate
8
that is at least as great as the distance by which front legs
18
and
22
depend from hinge plate
8
. On the other hand, in order to minimize cost, the rear legs
20
and
24
for an embodiment of the invention likewise extend no further than absolutely necessary to provide such lateral support. It has been found that when the front legs
18
and
22
depend from the hinge plate
8
no further than about three-fourths the distance between the front faces of the front legs
18
and
22
and the pivot axis
27
, the rear legs
20
and
24
for an embodiment of the invention preferably depend a distance from hinge plate
8
that is at least one and three-fourths times the distance by which the front legs
18
and
22
depend from hinge plate
8
in order to provide sufficient lateral support to prevent splitting of the edge portion of the cabinet component
26
. For example, in an embodiment of the invention, when the distance between the front aces of the front legs
18
and
22
and the pivot axis
27
is approximately seven-sixteenths inch, the front legs
18
and
22
depend about five-sixteenths inch from the hinge plate
8
, and the rear legs
20
and
24
depend about nine-sixteenths inch from the hinge plate
8
.
In an embodiment of the present invention, as the front and rear opposing legs
18
and
20
and the front and rear opposing legs
22
and
24
furnish support against splitting cabinet component
26
when fasteners
42
,
44
are received in the edge portion of the cabinet component, it is advantageous to position fastener openings
38
in hinge plate
8
substantially between front and rear opposing legs
18
and
20
and to likewise position fastener opening
40
in hinge plate
8
substantially between front and rear opposing legs
22
and
24
. In order to accommodate a moderate degree of adjustment of the door
28
after it is mounted to the cabinet component
26
on hinge
2
, the fastener openings
38
and
40
in hinge plate
8
can be slightly elongated as shown in FIG.
1
. Thus, after inserting fastening screws
42
and
44
into the edge portion of cabinet component
26
, the position of door
28
can be adjusted in a vertical direction relative to cabinet component
26
by loosening fastening screws
42
and
44
.
FIG. 4
shows a rear perspective view of a hinge plate
108
for an alternative embodiment of the present invention in which fastener openings
138
and
140
are disposed in rear legs
120
and
124
, respectively.
FIG. 5
shows a front perspective view of the hinge plate of
FIG. 4
, and
FIG. 6
shows a side view of the hinge plate of
FIG. 4
mounted on the face frame member
26
. Referring to
FIGS. 4-6
, hinge arm
6
extends from hinge plate
108
which is mountable on face frame member
26
. Hinge plate
108
has opposing front and rear edges
110
and
112
and opposing ends
114
and
116
. Rear legs
120
and
124
depend from rear edge
112
, and front legs
18
and
22
depend from front edge
110
, of hinge plate
108
. Rear legs
120
and
124
extend from rear edge
112
, for example, at or near opposing ends
114
and
116
, respectively, and front legs
18
and
22
depend from front edge
110
at or near opposing ends
114
and
116
, respectively. .
As shown in
FIG. 4
, rear legs
120
and
124
are provided with openings
138
and
140
respectively for receiving fasteners, such as fastening screw
142
shown in
FIG. 6
, for affixing the rear legs
120
and
124
depending from hinge plate
108
to face frame member
26
. Thus, in use, hinge cup
4
is affixed to cabinet door
28
, and hinge plate
108
is positioned on an edge portion of face frame member
26
with rear legs
120
and
124
confronting a surface portion of face frame member
26
adjacent the edge portion of the face frame member. With hinge plate
108
and rear legs
120
,
124
so positioned, fasteners, such fastening screw
42
can be inserted in openings
138
and
140
and screwed into surface portions of face frame member
26
proximate the edge portion of the face frame member
26
.
This arrangement of inserting the fastening screws
42
in surface portions rather than an edge portion of face frame member
26
, for an embodiment of the present invention, takes advantage of a known characteristic of MDF, which is generally denser and stronger at or near the surface than toward the center. In other words, the fastening screws
42
are less likely to pull out of the MDF material under the weight of the door
28
on the hinge if screwed into surface portions rather than an edge portion of the face frame member
26
. In order to take further advantage of this known characteristic, and to assure inserting the fastening screws
42
as far as possible away from edge portion of the face frame member
26
, fastener openings
138
and
140
are disposed in rear legs
120
and
124
as near as possible to distal edges of rear legs
120
and
124
and as far away as possible from rear edge
1
12
of hinge plate
108
.
In the embodiment shown in
FIGS. 4-6
, front legs
18
and
22
likewise depend from the hinge plate
108
no further than about three-fourths the distance between the front faces of front legs
18
and
22
the pivot axis
27
, and the rear legs
120
and
124
likewise depend a distance from hinge plate
108
that is at least as great as and preferably at least one and three-fourths times the distance by which the front legs
18
and
22
depend from hinge plate
108
in order to cooperatively provide sufficient lateral support for the edge portion of the MDF cabinet component
26
to avoid splitting the MDF cabinet component when the fasteners
42
are tightened. Likewise, in this embodiment, when the distance between the front faces of front legs
18
and
22
and pivot axis
27
is approximately seven-sixteenths inch, the front legs
18
and
22
depend up to about five-sixteenths inch from the hinge plate
108
, and the rear legs
120
and
124
depend at least about nine-sixteenths inch from the hinge plate
108
.
Referring further to
FIGS. 4-6
, rear legs
120
and
124
are substantially perpendicular to hinge plate
108
, and substantially parallel to front legs
18
and
20
, respectively. Further, rear legs
120
and
124
are spaced apart from front legs
18
and
22
, respectively, by a distance that is substantially equal to the thickness “T” of face frame member
26
. Likewise, referring to
FIGS. 4-6
, in order to accommodate a moderate degree of adjustment of the door
28
after it is mounted to the cabinet component
26
on the hinge, fastener openings
138
and
140
are slightly elongated. Thus, after inserting the fastening screws
42
into the surface portion of face frame member
26
, the position of the door
28
can be adjusted in a vertical direction relative to the face frame member
26
by loosening the fastening screws
42
.
FIG. 7
shows an elevational view of the rear legs
120
and
124
with alternate embodiment fastener openings
139
and
141
, each of which is open to a distal edge of rear legs
120
and
124
, respectively, to enable sliding the rear legs onto fastening screws pre-mounted in face frame member
26
and easy removal of the hinge plate
108
by simply loosening the fastening screws without removing them.
FIG. 8
shows a front perspective view of a hinge plate
208
for another alternate embodiment of the present invention, which employs a front ledge
218
rather than a pair of front legs. A reason for the use of a pair of front legs in preceding embodiments is that material disposed between the front legs is utilized to form hinge arm
6
, as shown from example in FIG.
1
. However, in the embodiment of
FIG. 8
, the hinge plate
208
and the hinge arm member
202
are separate components. Thus, in this embodiment, the front ledge
218
extends across the entire width of the hinge plate
208
to provide maximum subjacent support for the edge portion of the cabinet component
26
.
FIG. 9
shows a rear perspective view of the hinge plate
208
of
FIG. 8
, and
FIG. 10
shows a side view of the hinge plate
208
of
FIG. 8
mounted on the face frame member
26
. Referring to
FIGS. 8-10
, there is shown various views of the alternate embodiment for use in a three-dimensionally adjustable hinge.
FIG. 11
shows an exploded view of the hinge of
FIG. 8
so that all the individual parts of the hinge can be more readily seen and understood. The hinge of
FIGS. 8-11
includes a hinge cup
4
, a hinge arm member
206
, an intermediate member
262
, and a hinge plate
208
.
FIG. 12
is a perspective view of the intermediate plate
262
, and
FIG. 13
is a perspective view of the hinge plate
206
for the embodiment of
FIGS. 8-11
. Hinge cup
4
is mountable flush in a bore hole in the back of a door
28
with fastening screws in a known manner, and includes a spring to facilitate automatic closing of the door. Hinge plate
208
is adapted to be affixed to the doorframe
26
.
In the embodiment of
FIGS. 8-13
, hinge arm member
206
has a circular aperture
242
to receive an adjusting screw
215
. Intermediate member
262
has an elongated aperture
264
, a circular aperture
266
, and a pair of bent projections
260
. Hinge plate
208
is somewhat T-shaped and has a pair of elongate apertures
238
and
240
and a circular aperture
229
. Hinge plate
208
is attachable to frame
26
via two fastening screws
42
. Hinge arm member
206
has an arm end pivotably attached to hinge cup
4
on a pivot axis
27
via hinge pin
219
. Hinge arm member
206
is also pivotably attached to intermediate member
262
on a pivot axis via pin
218
fastened through hinge arm member
206
and intermediate member
262
. Intermediate member
262
is slideably connected to hinge plate
208
via a pair of L-shaped bent projections
209
and
211
on the base plate
208
that form a channel to slideably receive intermediate member
262
. Intermediate member
262
is also slideably connected to base plate
208
with a cam or eccentric screw
213
via the elongated aperture
264
in the intermediate member
262
and the circular aperture
229
in the hinge plate
208
. Hinge arm member
206
is also adjustably connected to intermediate member
262
via adjustment screw
215
through aperture
242
in hinge arm member
206
and aperture
266
in intermediate member
262
.
Adjustment screw
215
cooperates with the circular aperture
242
in hinge arm member
206
and the circular aperture
266
in intermediate member
262
to allow limited pivotal adjustment of hinge arm member
206
relative to intermediate member
262
(i.e., side to side adjustment of door
28
). When adjustment screw
215
is turned, hinge arm member
206
moves pivotably relative to intermediate member
262
on a pivot axis defined by pin
218
, thereby allowing side-to-side adjustments of door
28
to be made, for example, so that the desired spacing of the door from opposite sides of the cabinet door opening can be adjusted. The cam or eccentric screw
213
is mounted in the hinge plate
208
by means of a projection inserted in circular aperture
229
, and the cam or eccentric screw
213
extends through the elongated hole
264
in the intermediate member
262
. When cam screw
213
is turned, intermediate member
262
and hinge arm member
206
connected to intermediate member
262
via pin
218
move relative to hinge plate
208
slideably to and fro in the channel formed between bent projections
209
,
211
on hinge plate
208
, so that a desired alignment of the front face of the door
28
with the front of the cabinet can be adjusted.
In the embodiment of the invention shown in
FIGS. 8-13
, front ledge
218
depends from the hinge plate
208
no further than about three-fourths the distance between the front face of front ledge
218
and the pivot axis
27
as shown in
FIG. 10
, and the rear legs
20
and
24
depend a distance from hinge plate
208
that is at least as great as and preferably at least one and three-fourths times the distance by which the front ledge
218
depends from hinge plate
208
, in order to cooperatively provide sufficient lateral support for the edge portion of the MDF cabinet component
26
to avoid splitting the MDF cabinet component when the fasteners
42
are tightened. Likewise, in this embodiment, when the distance between the front face of front ledge
218
and pivot axis
27
is approximately seven-sixteenths inch, the front ledge
218
depends up to about five-sixteenths inch from the hinge plate
208
, and the rear legs
20
and
24
depend not more than about nine-sixteenths inch from the hinge plate
208
.
Referring further to
FIGS. 8-13
, rear legs
20
and
24
are substantially perpendicular to hinge plate
208
, and substantially parallel to front ledge
218
. Further, rear legs
20
and
24
are spaced apart from front ledge
218
by a distance that is substantially equal to the thickness “T” of face frame member
26
. Likewise, referring to
FIGS. 8-13
, in order to accommodate a moderate degree of adjustment of the door
28
after it is mounted to the cabinet component
26
on the hinge, fastener openings
238
and
240
are slightly elongated. Thus, after inserting the fastening screws
42
into an edge portion of face frame member
26
, the position of the door
28
can be adjusted in a vertical direction relative to the face frame member
26
by loosening the fastening screws
42
.
In a further aspect of an embodiment of the present invention, for reasons, for example, of economy and esthetics, mounting plates
8
,
108
, and
208
are made of metal, such as steel, that has a thickness not greater than about one to one and two-tenths millimeters. In trials using mounting plates made from inexpensive ordinary steel of such thickness, it has been found that the mounting plates deform when force is applied, such as by tightening the fastening screws against the mounting plate, and the mounting plate simply bends, providing little or no subjacent support to the edge portion of the cabinet member
26
, so that the hinge and supported door fall off the cabinet. In order to overcome this deficiency, an embodiment of the present invention includes post forming heat treatment to obtain the desired characteristics of surface hardness and rigidity of the steel mounting plate. For example, heat treating of the steel for mounting plates
8
,
108
, and
208
for wear involves addition of carbon, with or without nitrogen, to impart a surface layer of controlled thickness and increased hardness and rigidity and wear resistance to the mounting plate. In addition, the remaining inner core of the steel mounting plate can have its physical properties modified by heating and cooling temperatures and rates to maintain or increase strength.
Various preferred embodiments of the invention have been described in fulfillment of the various objects of the invention. It should be recognized that these embodiments are illustrative of the principles of the present invention. Numerous modifications and adaptations thereof will be readily apparent to those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, the invention is limited only by the following claims.
