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

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.
