This invention relates to an adjustable hinge that provides the ability to adjust a hinge in two orthogonal directions after the hinge is attached to a fixed member and a swinging member.
In mounting a door to a frame, it is often difficult to obtain precisely the desired position of the door relative to the frame. For this reason, it is common for door manufacturers to market pre-hung doors in which the door is mounted to the frame at the factory under controlled conditions so that precise positioning of the door can be obtained. The door and frame assembly is then shipped as a unit to the construction site for installation into an opening formed in a wall.
However, there are times when pre-hung doors cannot be employed and it is necessary to hang a door in an existing opening in which a frame has been constructed. In addition, not all doors for new construction are available in pre-hung form, making it necessary to construct a frame within an opening and to fit the door into the frame. In these instances, obtaining precise positioning of the door within the frame is a difficult and time consuming task even for the most skilled workman.
Hinges are also used to mount metal or wooden swinging gates to posts for outdoor usage. Such gates must be positioned and mounted as they are being installed. It is difficult to precisely obtain the desired position of the gate relative to the post to which it is being mounted. Since such gates are not received pre-hung alike doors and frames used indoors, there is always some difficulty in mounting such gates. In addition, even after gates are hung, the poles to which the gates are attached via hinges often shift as the earth settles in which the poles are set. As a result the bottom of the gate sags down and too often hits the ground and/or hits an adjacent pole of the fence to which latching side of the gate latches. This is an unacceptable situation.
Thus, there is a need in the art for an adjustable hinge that makes it much easier to install a door, gate or swinging member and to readjust the positioning of the door, gate or swinging member at a later time.
The invention will be better understood upon reading the following detailed description in conjunction with the drawing in which:
In the following detailed description the novel hinges described are described as being used with a door or gate, but the hinge may be used in any application where one member is connected to another member and must move in a hinged fashion therewith. All the parts of the preferred embodiment of the hinges disclosed herein are made from metal, but in alternative embodiments of the invention where light loads are contemplated, some of the parts may be made from tough plastics. Further, while the novel hinges are described hereinafter as being used with a door or gate, they hinges may be used with a swinging member that swings about its top edge.
In the following description
In Figure shown 1 is shown a blow up drawing showing the individual parts that make up a manually adjustable hinge 10. There is a metal plate 11 that is mounted to a door jam, post or other fixed member 33 using screws or bolts (not shown) that pass through holes 13. While two holes 13 are shown there may be more than two holes.
There is a plate 12 that is mounted to a swinging door, gate or other swinging member 32 using screws or bolts that pass through holes 13a. While four holes 13a are shown there may be more or less than four holes 13a.
When manually adjustable hinge 10 is to be used to mount a metal gate, door or other swinging member 33 to a doorjamb, post or other fixed member 32 that is also made of metal, rather than wood or other material, metal plates 11 and 12 may be eliminated. Instead metal bracket 11 may be welded or otherwise fastened to a metal post, door jamb or other fixed member 33; and metal bracket 12 may be welded or otherwise fastened to a doorjamb, post or other fixed member 32. Alternatively, upper hinge 10 may be attached to a combination of a wooden or metal gate or door 33 and a wooden or metal post or jamb 32. As appropriate one of metal plates 11 and 12 may be eliminated for such configurations.
Bracket 14 is U-shaped with its legs 14a and 14b being vertical to the plane of plate 11. Bracket 14 is made very sturdy because it bears the weight of a gate, door or other swinging member 33. Legs 14a and 14b of bracket 14 are oriented perpendicular to the plane of plate 11 and each has a hole there through (not shown) that is larger than the diameter of a hinge pin bolt 17. Hinge pin bolt 17 passes through the hole through each of legs 14a and 14b as shown in
First connecting member T-bracket 16 also has a horizontal portion 16b in which is a threaded hole 16c the purpose of which is described hereinafter with reference to
Second connecting member bracket 15 is made of strong metal, is tubular in shape and has a hole coaxially through it. The diameter of threaded extension 18 permits it to pass through the hole. Second connecting member bracket 15 is welded to metal plate 12 as shown in
Threaded extension 18 is headless and its left end passes through second connecting member bracket 15 and screws into threaded hole 16c of first connecting member T-bracket 16 where it is welded. Thereafter, during assembly nut 21 is first turn onto threaded member 18, then second connecting member bracket 15 welded onto plate 12 is slid onto threaded extension 18 so extension 18 passes through the longitudinal hole through bracket 15. Then nut 22 is threaded onto the outer end of extension 18, and finally locked nut 18a is turned onto the outer end of threaded extension 18 as shown in
During assembly second connecting member bracket 15 is welded to metal plate 12 as shown in
When an upper hinge 10 is utilized its metal plate 11 is attached to a fence post, door jamb or other solid member 32, and its metal plate 12 is attached to a gate, door or other swinging member 33 as previously described. After mounting, to adjust the height of the gate, door or other member 33 off the floor or ground, nut 20 is first loosened and the hexagonal head 17a of hinge pin bolt 17 is turned clockwise or counter clockwise. Since the threads of hinge pin bolt 17 are being turned in the mating threads in the interior of the vertical part of bracket portion 16a, first connecting member T-bracket 16 moves up or down along the threads of hinge pin bolt 17 as the bolt is turned. This moves the gate, door or other swinging member 33 attached to metal plate 12 up or down to adjust its height from the ground or floor. When hinge pin bolt 17 as a right handed thread, as the head 17a is turned clockwise looking down from the top in
When the vertical adjustment is completed, using the same wrench nut locking 20 is turned so that it is tight against lower leg 14b of bracket 14 to function as a jam nut to prevent hinge pin bolt 17 from rotating thereafter. This is important because any later rotation of bolt 17 will change the vertical adjustment of the door, gate or other swinging member 33.
If at a later time it is desired to readjust the height of the gate, door or other swinging member 33 locking nut 20 is first loosened and then head 17a of hinge pin bolt 17 is rotated to move first connecting member T-bracket 16 up or down along the threads of hinge pin bolt 17 as previously described. When the height adjustment is completed locking nut 20 is again tightened against lower leg 14b to prevent hinge pin bolt 17 from rotating. U-bracket 14 is made of heavy gauge metal that it is not deformed when locking nut 20 is tightened against lower leg 14b. It is also important that bracket 14 be made of heavy gauge metal because a lot of weight of the gate or door 33 is supported by this bracket.
To adjust the horizontal distance of the gate, door or other swinging member 33 to which metal plate 12 is fastened, from metal plate 11 and the post or jamb 32 to which is connected, locking nuts 21 and 22 are turned so they are backed away from either end of second connecting member bracket 15 and are not jammed against bracket 15. If the gate or door is to be moved away from plate 11 and the post or doorjamb 32 to which is attached, locking nut 22 is turned to move it to the right. Then nut 21 is then turned to move to the right and push against the left end of bracket 15 which thereby forces plate 12 and the gate or door 33 attached to it to the right.
Conversely, if plate 12 and the gate or door 33 to which it is attached is to be moved closer to the post or jamb 32, nut 21 is turned to move it to the left and nut 22 is turned against the right end of bracket 15 forcing it closer to the post or doorjamb 32. When the upper part of the gate or door 33 is spaced the correct distance from the post 32, locking nut 21 is turned against the left end of second connecting member bracket 15. Locking nuts 21 and 22 are then turned slightly against bracket 15, thereby jamming the nuts 21 and 22 so they are prevented from turning. This maintains the horizontal adjustment of hinge 10.
When the gate or door 33 is spaced the correct distance from the post or jamb 32, locking nut 22 is turned tightly against the right end of second connecting member bracket 15. Locking nuts 21 and 22 are then both locked against bracket 15, thereby jamming the locking nuts so they are prevented from inadvertently turning. This maintains the new horizontal adjustment of hinge 10.
In
There is a plate 12 that is mounted to a swinging door, gate or other swinging member 33 using screws or bolts that pass through holes 13a. While four holes 13a are shown there may be more or less than four holes 13a.
When self adjusting hinge 30 is to be mounted to a door or gate 33 that is made of metal, rather than wood or other material, metal plates 11 and 12 may be eliminated. Instead metal bracket 14 may be welded or otherwise fastened to a post, doorjamb or other fixed member 32 made of metal, and metal bracket 15 may be welded or otherwise fastened to a metal gate, door or other swinging member 33 made of metal. Alternatively, upper hinge 10 may be attached to a combination of a wooden or metal gate/door 33 and a wooden or metal post or jamb 32. As appropriate the one of metal plates 11 and 12 may be eliminated for such configurations.
Bracket 14 is U-shaped with its legs 14a and 14b being vertical to the plane of plate 11. Bracket 14 is made very sturdy because it helps bear the weight of a gate, door or other swinging member 32. Legs 14a and 14b of bracket 14 are oriented perpendicular to the plane of plate 11 and each has a hole there through (not shown) that is slightly larger than the diameter of a non-threaded hinge pin 26. Hinge pin 26 passes through the hole through each of legs 14a and 14b as shown in
First connecting member T-bracket 28 also has a horizontal portion 28b in which is a threaded hole 28c the purpose of which is described hereinafter with reference to
Second connecting member bracket 15 is made from strong metal, is tubular in shape and has a hole coaxially through it. The diameter of threaded extension 18 permits it to pass through the hole. Bracket 15 is welded to metal plate 12 as shown in
Threaded extension 18 is headless and its left end passes through second connecting member bracket 15 and screws into threaded hole 28c of first connecting member T-bracket 28 where it is welded. Thereafter, during assembly nut 21 is first turn onto threaded extension 18, then bracket 15 welded onto plate 12 is slid onto threaded extension 18 so extension 18 passes through the longitudinal hole through bracket 15. Then nut 22 is threaded onto the outer end of extension 18, and finally lock nut 18a is turned onto the outer end of threaded member 18 as shown in
During assembly and bracket piece 15 is welded to metal plate 12 as previously described. Nut 21 is turned onto threaded extension 18 until it is approximately as shown. Piece 15 on plate 12 is then slipped over threaded extension 18 until it rests against nut 21. Nut 22 is then turned onto threaded extension 18 until it is approximately as shown against the right end of bracket piece 15. Nuts 21 and 22 function as locking jam nuts as described hereinafter and are used for the horizontal adjustment of the door or gate on which hinge 30 is mounted. Finally, lock nut 18a turned onto the right end of threaded extension 18. Alternately, a standard nut with a thread lock compound on its threads may be utilized.
When a hinge 30 is utilized its metal plate 11 is attached to a fence post, doorjamb or other solid member 33, and its metal plate 12 is attached to a gate, door or other swinging member 32 as previously described. With hinge 30 there is no vertical adjustment to set the height of the gate or door 33 off the floor or ground. That adjustment is made solely with threaded hinge pin bolt 17 of upper hinge 10 as previously described. As first connecting member T-bracket 16 in
To adjust the horizontal distance of the gate, door or other swinging member 33 to which metal plate 12 is fastened, from metal plate 11 and the post or jamb 32 to which is connected, locking nuts 21 and 22 are turned so they are backed away from either end of metal bracket 15 and are not jammed against bracket 15. If the gate or door 33 is to be moved away from plate 11 and the post or doorjamb 32 to which is attached, locking nut 22 is turned to move away from bracket 15. Then nut 21 is then turned to move to the right and push against the left end of bracket 15 which thereby forces plate 12 and the gate or door 33 attached to it to the right.
Conversely, if plate 12 and the gate or door 33 to which it is attached is to be moved closer to the post or jamb 32, nut 21 is turned closer to first connecting member T-bracket 28 and nut 22 is turned against the right end of bracket 15 forcing it closer to the post or jamb 32. When the lower part of the gate or door 33 is spaced the correct distance from the post 32 locking nut 21 is turned against the left end of bracket piece 15. Locking nuts 21 and 22 are then turned slightly against bracket 15, thereby jamming the nuts 21 and 22 so they are prevented from turning. This maintains the new horizontal adjustment of hinge 30.
After installation of a set of hinges 10 and 30 to a post and gate 33 the post may shift in the ground and the outer, bottom end of the gate 33 may sag and touch the ground. To correct for this sag upper hinge 10 and middle and lower hinges 30 may be re-adjusted. Upper hinge 10 is re-adjusted to move plate 12 closer to plate 11 while middle and lower hinges 30 or re-adjusted to move them away from their plate 11.
