Abstract

A hinge for mounting of doors featuring adjustment in three planes to thereby adjust the position of the door in the jam in three planes. The device features tool engageable eccentric bushings (54, 64) which engage a hinge pin (60) allowing it to rotate around the axis of the hinge members for adjustments horizontally and for compression in and out of the door frame. Vertical adjustment is provided by an adjustment screw (68, 168) threadably engaged with a lower hinge member which translates the hinge pins up and down thereby moving the attached door vertically for adjustment. Horizontal adjustment is provided by either sliding adjustable mounting plates (22) or a second eccentric bush which may be rotated. Cover plates (74, 174, 190) are provided which cannot be removed unless the door is in an open position out of the door jam thereby preventing removal of the door.

Description

THREE DIRECTIONAL ADJUSTABLE HINGE

FIELD OF THE INVENTION

This invention relates to hinges for doors which swing on a mounting surface and into a closed mount in a jam. More particularly it relates to a heavy-duty hinge facet mounting hinge that may be adjusted in three planes or directions and provides for all the adjustment and securing mechanisms to be concealed. Using a unique system of eccentric bushings and pivots the disclosed device provides adjustment using simple tools in three planes. Also provided for security purposes are mounting plates which cannot be removed unless the door is in an open position out of engagement in the door jam. These face plates prevent access to the screws used to mount the hinge to the door and mounting surface increasing security.

BACKGROUND OF THE INVENTION

Conventional hinges have been used on doors, gates and cabinets for many years, basically consisting of jam-mounted hinges that mount between the door jam and the edge of the door. With this style of hinge there are generally no adjustments and the mounting screws are concealed between the door and the door jam. The other style of hinge is the face-mounted hinge where the hinge is mounted on the side of the door and the side of the door jam, allowing that the mounting screws are accessible. With the mountings accessible the doors can be readily removed and the door forced open.

Hinges are generally comprised of a first and second hinge member inter-connected by the means of a hinge pin for a relative pivotal movement. The first hinge member mounts to the door with hinge mounting hardware, normally wood screws for wood doors and sheet metal screws on metal doors . The second hinge member mounts to the door jam with the same hinge mounting hardware as the first hinge member. When doors are mounted properly, the door and door jam form a tight seal, but when they are not located properly or there is any shrinkage in the material or settling of the structure, there may be a space between the door and the jam at the top, bottom, or the sides. There are other occasions when the doors are not set deep enough and do not form a seal against the jam. These spaces often account for a draft of air entering the room and a great deal of either heat or cooling losses. Additionally, when mounting a door, it is difficult to locate the second hinge exactly in alignment with the first hinge on a two hinge door and even more difficult to align the two additional hinges exactly on a three hinge door. The convenience of a fully adjustable face-mounted hinge will allow that doors can be attached and aligned for the optimum seal fit to the door jams. Concealing the mounting hardware has presented an additional problem with the face-mounted hinges in that the hardware can easily be removed and the door forced open. This patent offers not only a fully adjustable hinge, but also a hinge that when mounted has all of the mounting and adjustment points concealed.

Patent No. 3,596,307 of Samuel Kolmetsky describes a device to be mounted in a metal buck or wooden jamb of a door so that conventional hinges may be used to hang the door while the device permits connecting the position by the hinge so that the door may be adjusted and aligned. This patent deals with a jam-mounted hinge, not a face mounted hinge that has adjustment in only two planes .

Patent No. 4,748,717 of David Osborne teaches of a hinge for doors or gates that has two adjustments up or down and in or out. Both of these adjustments are made in the barrel portion of the hinge with relation to the hinge pin. This patent allows that all the mounting hardware is accessible and is limited to adjustments in two directions only.

Patent No. 4,785,498 of Othmar Brotschi discloses an unusual style of door and window hinge that is adjustable in three planes during and after installation, but leaves all the mounting and adjustment hardware exposed, along with the fact that it does not mount in a conventional manner.

Patent No. 4,815,162 of John E. McAteer describes an independently adjustable top and bottom hinge pin assembly. This style of hinge is not commonly used on structures, due to the fact that the lower L-shaped bracket does not mount into a conventional door jam.

Patent No. 5,339,493 of Robert J. Maclntyre teaches of an adjustable hinge for interposition between a door and frame. This hinge has only horizontal and vertical adjustments and is mounted between the door and the jam, not being a face-mounted hinge .

Patent No. 5,713,105 of Mark H. Toomey tells of a vertically adjustable hinge, which permits easy, small and precise vertical adjustments. This hinge is limited to adjustments in one plane only and is a jam-mounted hinge.

None of the foregoing prior art teaches or suggests the particular unique adjusting and mounting features incorporated within this invention. There is as such an unmet need for a hinge that provides a secure mount that cannot be removed unless the door is open and provides for adjustment in 2 planes so the door may be adjusted in relation to its engagement with the encompassing jam. Such a device should provide the means for adjustment using simple tools and without the need to dismount the door or disassemble the hinges used.

SUMMARY OF THE INVENTION

The preferred embodiments of this invention provides a unique face mounted door hinge that has the capability of being adjustable in three planes, vertically, (up and down) , horizontally, (from side to side) and compression or in-and out of the door frame. Additionally when this hinge is fully installed and the door is closed, all door mounting screws and hardware are inaccessible which prevents removal of the door by persons who might wish to enter a locked door. This hinge also offers the benefit of riding on smooth nylon or similar synthetic material bushings. Face mounted door hinges mount on the face of the door and door jam rather than between the edge of the door and the door jam. This three directional adjustable hinge is provided in two embodiments in which the first hinge member attaches to the door by the means of mounting screws through the internal mounting plate into the door face . In one embodiment the internal mounting plate retains the horizontal adjusting screw and nut that translates the first hinge member in the horizontal direction, positioned by guide pins registering in guide pin slots in the first hinge member body. Additional door edge mounting tabs are located on the internal mounting plate to further secure the hinge by attaching to the edge of the door . The first hinge member body also incorporates the in-and-out adjustment orifice whereby the in-and-out adjuster is positioned by the in-and-out adjustment screw. Elongated orifices in the first hinge member body and the nylon in-and-out guide bushing create a smooth pathway whereby the hinge pin is moved by the in-and-out adjuster. The hinge pin comprised of the hinge pin shaft and the nylon hinge pin bushing form the pivotal member, whereby the first hinge member and the second hinge member are connected. The hinge pin can be inserted into either side of the first hinge member simply by relocating the nylon in-and-out guide bushing and the end cap. With the hinge pin bushing inserted into the hinge pin bushing orifice, located in the second hinge member, vertical adjustments are made to the hinge by rotating the vertical adjustment screw either in or out. The second hinge member is attached to the door jam by means of mounting screws and locator pins. With the first hinge member and the second hinge member attached and the door in the fully opened position, the decorative cover plate is installed by sliding it downward over the first hinge member body engaging the locking member and the locating tabs and attaching by the means of the cover plate mounting screw accessible at the back of the first hinge member, between the edge of the door and the door j am .

An alternate embodiment of this invention would incorporate all the unique features of the preferred embodiment but designed for applications with aluminum doors and door jams. This hinge is also a face mounted door hinge that has the capability of being adjustable in three planes, vertically, horizontally, and compression or in-and out of engagement in the door frame. Additionally when this hinge is fully installed and the door is closed all the adjustable features and mounting hardware are inaccessible .

One preferred embodiment of the three directional adjustable hinge also consists of the first hinge member that attaches to the door by the means of mounting screws through the internal mounting plate into the door face. The internal mounting plate retains the horizontal adjusting screw and nut that translates the first hinge member in the horizontal direction, positioned by guide pins registering in guide pin slots in the first hinge member body. The first hinge member body also incorporates the in-and-out adjustment orifice whereby the in-and-out adjuster is positioned by the in-and-out adjustment screw. Elongated orifices in the first hinge member body and the nylon in-and-out guide bushing create a smooth pathway whereby the hinge pin is moved by the in-and-out adjuster. The hinge pin comprised of the hinge pin shaft and the nylon hinge pin bushing form the pivotal member whereby the first hinge member and the second hinge member are connected. The hinge pin can be inserted into either side of the first hinge member simply by relocating the nylon in-and-out guide bushing and the end cap. With the hinge pin bushing inserted into the hinge pin bushing orifice, located in the second hinge member the vertical adjustments are made to the hinge by rotating the vertical adjustment screw either in or out. The differences in the alternate embodiment additionally lay in the second hinge member and the means of attachment to the door jam. The second hinge member in this case attaches to the door jam adjacent to the first hinge member and requires a cover plate attached by means of a cover plate mounting screw, accessible from the back between the door and door jam when the door is fully opened.

A second preferred embodiment of the disclosed device features the first and second hinge members interconnected for relative pivotal movement by a pivot pin. Cover plates are provided for both hinge members that are only removable when the door is in an open position.

This embodiment incorporates a compression adjustment on a first plane, or in and out of the door jam, using a tool rotatable eccentric bush, and it has a hinge pin engageable passage with a center axis parallel but slightly off center from the center axis of the bush itself. Rotating the eccentric bush with a tool will move the door in and out of its fit within the door frame .

Horizontal adjustment in this embodiment is provided by the engagement of the pivot pin in an off center axial chamber in a pivot bush which when rotated by a tool will rotate its engagement with the pivot pin around the center axis of pivot pin mount in the lower hinge member. This provides the horizontal adjustment when the tool engaging the pivot bush.

Finally, this embodiment provides adjustment in the third plane or vertical adjustment by rotating an adjustment screw threadably engaged with a pivot passage in the lower hinge member. By rotating the adjustment screw, the door may be adjusted vertically up and down.

Although this invention is in the field of heavy-duty hinges, the unique principles disclosed with this patent will pertain to any size and style of hinge and it is appreciated that these be covered within the scope of this patent. As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing of other devices, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent construction insofar as they do not depart from the spirit and scope of the present invention.

An object of this invention is to create a door face mounted hinge that has adjustments in three planes, horizontal, vertical and in-and -out. Another object of this invention is to create a door face mounted hinge that has all the mounting hardware and adjustment mechanisms fully enclosed.

An additional object of this invention is to create a hinge that pivots on smooth nylon bushings .

These together with other objects and advantages which become subsequently apparent reside in the details of the construction and operation as more fully hereinafter described and claimed, reference being made to the accompanying drawings forming a part thereof, wherein like numerals refer to like parts throughout .

Referring now to the drawings, wherein similar parts of the invention are identified by like reference numerals, there is seen in Figure 1 an exploded view of the three directional embodiment of the device 10 forming an adjustable hinge consisting of the first hinge member 12 and the second hinge member 14 interconnected for relative pivotal movement by the means of hinge pivot pin 16.

The first hinge member 12 is composed of the first hinge member body 18 having an internal body cavity 20 housing the internal mounting plate 22 that mounts the hinge to the door by the means of four mounting screws 24 through orifices 26 and aligned by two guide pins 28. The internal mounting plate 22 is further attached to the door edge by the means of two, door edge mounting tabs 30.

The three directional adjustable hinge embodiment of the device 10, is adjustable in three planes. It may be adjusted horizontally using a means for horizontal adjustment which in this embodiment is provided by the horizontal adjustment screw 32 held within the horizontal adjustment screw head retainer cavity 34 and the horizontal adjustment nut 36 held within the horizontal nut retainer cavity 38. By rotating the horizontal adjustment screw 32 the internal mounting plate 22 is adjusted horizontally within the internal body cavity 20 of the first hinge member bodylδ thereby adjusting the door horizontally in relation to the first hinge member 12 and in relation to the door's position in the jam.

The first hinge member body 18 also incorporates a compression adjustment orifice 40, whereby the in-and-out adjuster 42 positioned by the in-and-out adjuster screw 44 may be moved in and out thereby providing a means for compression adjustment of the door in the jam by moving the first hinge member 12 in and out in relation to the pivot pin 16 and the second hinge member 14. In-and-out adjuster screw 44 and in-and-out adjuster 42 are held in place by the flat washer 46 and snap ring 48, within the in-and-out adjuster orifice 40. Elongated orifices 50 in the first hinge member body 18 with the counter bore 52 in either side accommodate the nylon in-and-out guide bushing 54 with an elongated orifice 56, matching the elongated orifice 50 in the first hinge body 18 and the end cap 53. Additionally, nylon in-and-out guide bushing 54 incorporates a shoulder 58 to allow for a smooth rotation between the first hinge member 12 and the second hinge member 14. The elongated slots 50 in the first hinge member body and the elongated slot 56 in the nylon in-and-out guide bushing 54 are substantially the same width as the diameter of the hinge pivot pin shaft 60 on the hinge pivot pin 16 also matching the diameter of the groove 62 on the in-and-out adjuster 42, so when the in-and-out adjuster 42 is moved by the in-and-out adjustment screw 44, the first hinge member 14 and the attached door are moved in and out in relation to the hinge pin shaft 60 and the second hinge member 14. Hinge pivot pin 16 incorporates a nylon anti-rotation hinge pin cap 64 that fits snugly within the hinge pin cap orifice 66 in the second hinge member 14. The other end of the hinge pin cap orifice 66 is threaded to accommodate the vertical adjustment screw 68 that the nylon anti-rotation cap 64 is resting upon. Rotating the vertical adjustment screw 68 thereby provides a means for vertical adjustment. The second hinge member 14 is attached to the door jam by the means of two mounting screws 70 and positioned by two locator pins 72.

With the first hinge member 12 attached to the door frame and the second hinge member 14 attached to the door jam, and the door in the fully opened position the decorative cover plate 74 is installed by sliding it downward over the first hinge member body 18 engaging the locking member 76 into groove 78 and locking tabs 80 under edges 82, and attaching by the means of the cover plate mounting screw 84.

Figures 6 illustrates a second preferred embodiment 110 of the device featuring means for adjustment in three planes consisting of the first hinge member 112 and the second hinge member 114 interconnected for relative pivotal movement by the means of hinge pivot pin 116. The first hinge member 112 is composed of the first hinge member body 118 having an internal body cavity 120 with a mounting surface 122 through which the hinge is attached to a door by the means of mounting screws 24 similar to those as shown in figure 1 through orifices 126 communicating through the mounting surface 122. A bush passageway 113 having a center axis therethrough is formed into the first hinge member 112 and sized to accommodate the insertion of an eccentric bush 164 therein. A pivot passage 115 having a center axis therein is formed into the second hinge member 114 and sized to accommodate engagement with the exterior of an eccentric pivot bush 165 therein.

A first cover plate 174 is held in place by a mounting screw 84 which effectively seals the body cavity 120 of the first hinge member 112 from access when the door is closed since the mounting screw 84 cannot be removed unless the door is open to provide access to the mounting screw 84. This provides a means for prevention of removal of the first hinge member 112 from the door when the door is in the closed position inside the jam, thereby enhancing security of the closed and locked door to unauthorized entry. A second cover plate 190 operates in the same fashion as the first cover plate 174 and is held in place by a mounting screw 84 which effectively seals the member cavity 123 from access when the door is closed providing a means for prevention of removal of the second hinge member 114 from the surface on which it mounts when the door is in the closed position.

This embodiment provides the means for adjustment in three planes as in the first embodiment. A means for compression adjustment or in-and-out adjustment of the door within the door frame is provided by operation the eccentric bush 164. The eccentric bush 164 has a center axis in line with the center axis of the bush channel 113 when operatively mounted therein. In the bottom surface of the eccentric bush 164, as best seen in figure 8, an axial passage 163 is formed which has a passage center axis 161 parallel but slightly off center from the center axis of the eccentric bush 164. The passage 163 is sized to engage the exterior of the hinge pin 116 at the top end with the axis of the hinge 116 in line with the passage center axis. On the top end opposite the passage 163, an engagement slot 165 is formed. The engagement slot 165 is dimensioned to cooperatively engage a tool such as an alien wrench so that the tool may twist the eccentric bush 164 in its engagement in the bush channel 113 causing the passage center axis 161 and hinge pin center axis to rotate around the center axis of the bush channel 113 there by providing a means for compression adjustment of the attached door in and out of its engagement within the door frame by rotating the eccentric bush 164.

A means for horizontal adjustment is provided by the engagement of the pivot pin 116 at a bottom end with an axial chamber 167 in a pivot bush 168. As shown best in figure 7, the center axis 171 of the pivot bush 168 is parallel but slightly off center from the center axis 173 of the axial chamber 167 in a similar arrangement to the aforementioned off center axis of the passage 163 of the pivot bush. Horizontal adjustment is provided much as in the first embodiment but achieved slightly differently by rotation of the eccentric bush 164 using an engagement slot 165 in the bottom of the pivot bush 168 which is dimensioned to engage a tool such as an alien wrench inserted through the adjustment portal 169 within the pivot passage 115. Once so engaged with the engagement slot 165 of the pivot bush 168 the user may rotate the pivot bush 168 using the tool which rotates or translates the center axis 173 of the axial chamber 167 rotates around the center axis of the pivot bush 168 which is in line with the center axis of the pivot passage 115. This eccentric translation of the pivot pin 116 toward and away from the center axis provides the means for horizontal adjustment of the door in relation to the jam in which it is situated by horizontally moving the first hinge member 112 and an attached door, toward and away from the second hinge member 114.

Similar to that of the first embodiment of figure 1, this embodiment also employs a means for vertical adjustment is also provided in this second embodiment through the provision of a means to laterally translate the hinge pin 116 toward and away from the second hinge member 11 . As can be seen in figure 6 the hinge pin 116 is engaged on one end within the passage 163 of the eccentric bush 164 and on the other end with the axial chamber 167 of the pivot bush 168. An adjustment screw 167 has an exterior circumference which is threaded to engage cooperating threads in the lower end of the pivot passage 115. An adjustment portal 169 communicates through the adjustment screw 167 and is dimensioned for cooperative engagement with a tool such as an alien wrench so that the adjustment screw 167 may be rotated into and out of the pivot passage 115 by the tool rotating the engaged threads of both parts. The adjustment portal 169 must also have a sufficient in size to allow the tool for engagement with the pivot bush 168 to pass therethrough and rotate unimpeded to allow for the user to rotate the pivot bush for horizontal adjustment consequently the tool used for adjustment of the adjustment screw 167 will have a larger diameter than that used to rotate the pivot bush.

Finally, to complete the aesthetic appearance of this embodiment, endcaps 153 are inserted in cooperating recesses in the bush channel 113 of the first hinge member 112 and the pivot passage 115 of the second hinge member 114. The device herein shown in the drawings and described in detail herein disclose arrangements of elements of particular construction and configuration for illustrating preferred embodiments of structure and method of operation of the present invention. It is to be understood, however, that elements of different construction and configuration and other arrangements thereof, other than those illustrated and described, may be employed for providing a three directional adjustable hinge in accordance with the spirit of this invention, and such changes, alternations and modifications as would occur to those skilled in the art are considered to be within the scope of this invention as broadly defined in the appended claims.

As such, while the present invention has been described herein with reference to particular embodiments thereof, a latitude of modifications, various changes and substitutions are intended in the foregoing disclosure and will be appreciated that in some instance some features of the invention will be employed without a corresponding use of other features without departing from the scope of the invention as set forth in the following claims.
