DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings, wherein like numerals represent like parts throughout the several views, there is generally disclosed at 10 an adjustable hinge. The adjustable hinge 10 includes a frame leaf 11 having a plurality of mounting holes 11 a formed therein. The mounting holes are used to secure the frame leaf 11 to a frame (not shown). The frame leaf 11 is generally planar and suitable mounting screws or other mounting mechanisms may be utilized. The frame leaf 11 has two spaced knuckles 12 that are operatively connected to the frame leaf 11. The spaced knuckles 12 mate with a knuckle 13 on door leaf 14. End caps 12a may be provided to provide a finished look to the knuckles 12. The end caps 12a are optionally threaded so that they may be screwed into the knuckles 12. The end caps 12a have a slot 12b into which a tool is inserted to install and remove the end caps 12a. A threaded bore extends through the knuckles 12 and 13 and the leaves 11 and 14 are engaged together with a pivot pin 15 which enables the leaves 11, 14 to pivot with respect to each other. The door leaf 14 has a base member 14a that is operatively connected to the knuckle 13. Operatively connected, and preferably integral with the base member 14a is an insertion member 14b. The insertion end 14b has a leading edge 14c, a top edge 14d and a bottom edge 14e. A latch receiving opening 14f is formed in the top edge 14d. The latch receiving opening 14f has an end wall 14g that is generally parallel to the pin 15. An angled side wall 14h is generally at an angle to the end wall 14g. The door leaf 14 has a top surface 15 and a bottom surface 16. A threaded bore 18 extends from the top surface 15 to the bottom surface 16. A screw 17 is threaded into the threaded bore 18. The screw 17 has an opening 17a in which a tool, such as a screwdriver or Allen wrench, may be inserted to rotate the screw 17 in the threaded bore 18. The insert member 14b is generally flat. However, three coined areas are formed in the insertion member 14b. Two smaller rectangular-shaped coined protrusions 19 protrude from the bottom surface 16 and are formed with their corresponding depressions 19a on the top surface 15. Another coined protrusion 20 extends upward, as viewed in FIG. 2, from the top surface 15 and the corresponding depression is formed on the bottom surface 16. The protrusions 19 are downward, as viewed in FIG. 2. The protrusions 19 and 20 have rounded, or pointed, apexes 19b and 20b.
Referring now, especially to FIGS. 4-8, there is shown an adjustable mounting assembly 21. The adjustable mounting assembly 21 is adapted and configured to be mounted to a door panel (not shown). The adjustable mounting assembly 21 includes a housing formed by a top member 22 and a bottom member 23. A slideable carriage 24 is positioned in the cavity formed by the top member 22 and bottom member 23. In FIGS. 4 and 5, a bevel gear assembly 25 and latch mechanism 26 is shown positioned in the slideable carriage 24. In FIGS. 6 and 7, the bevel gear assembly 25 and latch mechanism 26 is shown in place in the bottom member 23 with the carriage 24 removed. However, this is shown only for illustrative purposes, it being recognized that the assembly is generally positioned as shown in FIGS. 4 and 5. FIG. 8 shows the bevel gear assembly 25 and latch mechanism 26 in the bottom member 23 also for illustrative purposes. In FIG. 8, the top portion of the slideable carriage 24 has been removed so that the assemblies may be seen in position.
The slideable carriage 24 is generally a rectangular box, as best seen in FIG. 6. The slideable carriage 24 has a bottom member 24a, top member 24b, a first side 24c and a second side 24d. Preferably, this is formed from a single piece. It is appreciated that prior to completion of the bending of a single piece to form the box, the various components that are in the carriage may be required to be in position. Alternately, the carriage could be formed from multiple parts and later connected to form the carriage. As can be seen in FIG. 4, the side 24d extends only across a portion of the width of the carriage 24. Four mounting holes 24e are formed in the carriage 24, two in the top member 24b and two in the bottom member 24a. The mounting holes 24e are used to secure a latch block 27 in position. A generally L-shaped latch block 27 has four protrusions 27a, only three of which are shown in FIG. 6. The protrusions 27a are sized and configured to fit in the mounting holes 24e. The latch block 27 is positioned between the bottom member 24a and top member 24b and then compressed and a friction fit is formed to secure the latch block 27 in position. An L-shaped latch 28 has a latch member 28a operatively connected to a release member 28b. The latch member 28a is positioned in a bore 27b formed in the latch block 27. A spring 29 is positioned in a bore in the latch block 28 between the inside of the second side 24d and the end of the bore in latch block 28, thereby biasing the latch member 28a in a latched position, as shown in FIG. 6. There is enough compression left in the spring 29 so that the release member 28b may be pulled toward the second side 24d, thereby compressing the spring and moving the latch member 28a further into the latch block 27. The top of the release member 28b has a raised section 28c that acts as a pointer, as will be described more fully hereafter.
The top member 24b has a nut opening 30 and the bottom member 24a has a similar nut opening 31. A nut 32 is positioned, between the nut openings 30 and 31 such that it is captured in the openings 30, 31 and cannot rotate. A portion of the nut 32 extends into both of the openings 30 and 31. A second bevel gear 33 has a threaded rod 34 operatively connected thereto. The threaded rod 34 is threaded through the nut 32. A first bevel gear 35 is positioned to mesh with the second bevel gear 33, such that rotation of the first bevel gear 35 will cause rotation of the-second bevel gear 33, which is at 90 degrees thereto, although it is understood other angles may also be utilized. This will in turn cause rotation of the threaded rod within the nut 32. The first bevel gear 35 has an end cap 35a with a square opening that is adapted and configured to be rotated by a suitable means, such as an Allen wrench.
The adjustable mounting assembly 21 has a housing formed by the top member 22 and the bottom member 23. Referring now especially to FIGS. 4 and 5, the bottom 23 is generally rectangular and has a base 23a with a wall 23b that is operatively connected thereto and forms a wall on three sides of the base 23a. Four bosses 23c-23f are formed in the wall 23b. Each of the bosses 23c-24f have bores formed therein. Another hole 23g is formed in the base 23a. The hole 23g is sized and configured to receive the end of the shaft 35b of the first bevel gear 35. Also, a cavity 23h is formed by the wall 23b. The cavity 23h is above the hole 23g and the cavity 24h provides for a receptacle for the first bevel gear 35.
The top member 22 has a planar member 22a operatively connected to a wall 22b. The planar member 22a has two tapered holes 22c that positioned over bosses 23d and 23e. Two other holes 22d also have a tapered surface at the top but also have an additional cylindrical member 22e that depends below the bottom surface of the wall 22b. When the top member 22 is joined to the bottom member 23, the cylindrical members 22e are positioned in the holes of the bosses 23c and 23f and pinned to secure the top member 22 to the bottom member 23. The wall 22b has a rectangular opening 22f that is sized and configured to receive the frame leaf 11. The rectangular opening 22f, when assembled, is over a corresponding opening 24f in the slideable carriage 24. A first access opening 22g is formed in the planar member 22a. The first access opening 22g allows access for a tool to be inserted into the end cap 35a of the first bevel gear 35. A second access opening 22h is formed in the planar member 22a. This provides an access opening to the opening 17a of the screw 17. Finally, a third access opening 22i is also formed in the planar member 22a. This provides for access to the release member 28b of the latch 28. This third access opening 22i is also an indicator opening as a plurality of linearly spaced markings 36 are imprinted or otherwise placed on the planar member 22a.
The top member 22 and bottom member 23 form the housing which has a cavity which is sized and configured to receive the slideable carriage 24. As can be best seen in FIGS. 10-12, the walls 22b and 23b are spaced at a distance to be just slightly larger than the width of the slideable carriage 24. Also, in viewing FIG. 9, it can be seen that the height of the vertical carriage 24 is again just slightly less than the distance between the planar member 22a and base 23a, thereby further defining a path for the carriage 24 to slide. This provides for a path in which the slideable carriage 24 may slide in a direction parallel to the access of the pin 15. However, as can been seen in FIG. 8, there is room for the carriage 24 to move to allow for vertical adjustment, as will be described in more detail hereafter.
In operation, the leaf frame 11 is mounted to the frame of a door by screws through mounting holes 11a. Similarly, the adjustable mounting assembly 21 is mounted by suitable screws to a door through the holes 22c, 22d. It is preferred that the door be notched so that the adjustable mounting assembly 21 is more flush with the edge of the door. Such mountings are well known in the art and therefore are not shown in the drawings. Typically, three adjustable hinges 10 are used for each door. Further, it is recognized that the adjustable hinge 10, described thus far, has both a vertical and a horizontal adjustment. It is understood that either the horizontal or vertical features may be removed from the hinge, leaving a hinge that would not adjust both horizontally and vertically. Instead, a hinge could only adjust vertically or horizontally. In such a scenario, typically two horizontally adjustable hinges would be used, one at the top of the door and the other at the bottom of the door. A vertically adjustable hinge would then be used in the middle.
Once all of the adjustable hinges 10 that are to be used are mounted, the door is moved in position and the door leaf insertion member 14b, with the leading edge 14c in front, is moved into the slideable carriage 24 through the opening 24f. As the insertion member 14b moves into the slideable carriage 24, the top edge 14d will make contact with the latch member 28a and move the latch member 28a from a latched position to an unlatched position, compressing the spring. Then, as the insertion member 14b continues to be inserted into the slideable carriage 24, the latch member 28a will pass over the latch receiving opening 14f and the spring 29 will urge the latch member 28a to a latched position and catch on the latch receiving opening 14f. This will secure the door leaf 14 into the adjustable mounting assembly 21 and prevent removal unless the release member 28b is moved. It is appreciated that location of the end wall 14g on the insertion member 14b is determined so as to have a minimal amount of movement of the leaf 14 after the leaf 14 has been secured in position. It is appreciated the latch receiving opening may also be formed on the bottom edge 14e, in which case the latch mechanism would be moved to the other side also.
Referring now especially to FIGS. 10-12, the horizontal adjustment is shown in sequence. FIG. 12 shows the minimum panel gap, FIG. 11 the neutral panel gap and FIG. 10 the maximum panel gap. The horizontal adjustment is accomplished by placing a suitable tool through the opening 22h and then 24g to reach the opening 17a of the screw 17. Then, if it is desired to move the leaves further apart, the screw 17 is rotated counterclockwise and clockwise if the leaves are to be brought closer together. The movement of the leaves is affected because the screw 17 does not move up or down, as shown in FIG. 10. The screw is substantially the same height as the distance between the top member 24b and the bottom member 24a. Instead, the screw rotates and the threaded bore 18 causes the end of the door leaf 14 to move up or down. If the door leaf 14, at its end, moves down, the door leaf 14 pivots on the apexes 19b of the protrusions 19 on member 24b. If the end of the door leaf 14 moves upward, as shown in FIG. 12, the door leaf 14 will pivot on the apex 20b of protrusion 20 on member 24a. The coined protrusions give an overall thickness of approximately the distance between members 24a, 24b.
Referring now to FIGS. 1, 4, 7 and 8, the vertical adjustment will be described. It should be recognized that in FIG. 7, the slideable carriage 24 has been removed. Further, in FIG. 8 the bottom member 24b has been removed so as to better show the working of the adjustable hinge 10. To adjust the adjustable hinge 10 vertically, a suitable tool is placed in the end cap 35a and rotated. Rotation to the right will move the slideable carriage to the right, as shown in FIG. 8. Rotation of the first bevel gear 35 causes the second bevel gear 33, which is at 90 degrees, to rotate. This in turn causes the rotation of the threaded rod 34. Since the nut 32 is captured in the nut opening 30 and 31, rotation of the threaded knob will cause the nut 32 to move up and down the threaded rod 34. This in turn carries with it the carriage 24. Since the door leaf 14 is secured in the slideable carriage 24 by the latch mechanism 26, the door leaf 14 moves along with the slideable carriage 24 and allows for vertical adjustment. It is appreciated that the nut 32 could take other forms. For instance, there could be a threaded member that was operatively connected to the carriage 24. The threaded rod would then be positioned in the threaded member. The nut 32 is just one example of a threaded member that may be utilized. Further, the nut openings 30 and 31 are just one way of operatively connecting the threaded member, or nut, to the slideable carriage 24.
The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the. invention, the invention resides in the claims hereinafter appended.
