Filed May 17, 1966 INVENTOR. PAUL R. FERGUSON ATTORNEY United States Patent 3,407,433 PIVOTED DOOR MOUNTING Paul R. Ferguson, P.O. Box 203, Milldale, Conn. 06467 Filed May 17, 1966, Ser. No. 550,831 Claims. (Cl. 16-130) This invention relates to pivotally mounted doors, pivoted-door mounting constructions, and to correlated inventions and discoveries appertaining thereto.

Various factors in the construction of metallic doors and door jambs which are often formed of aluminum and/or with somewhat less precision than might be desirable-has emphasized the long-standing need for a pivoted door construction which is simple, economical, and free from any interference with easy and accurate vertical adjustment of a door, and which at the same time permits easy and effective adjustmentof the top or the bottom of the door or both in a direction generally widthwise of the door.

By means of the present invention this may be accomplished by the provision of one or more sets of cooperating axially movable threaded means (e.g. a screw and nut, or a screw and threaded bore) which extends in a direction generally perpendicular to the face of a door and which includes an element movable in said direction (e.g. a screw and/or a nut), either a screw or a nut (or both) on each of whatever number of sets of cooperating movable threaded members are present being provided with an inclined thrust surface adapted, upon the turning of itself or another element of the set (screw or nutas the case may be), to exert a thrust tending to move the door in a direction widthwise thereof. By the employment of such an arrangmeent, a door can be easily and effectively adjusted when hanging so as to fit its particular frame as precisely as possible.

When two sets of such threaded means are used, the two can be mutually adjusted and then tightened to lock the door in adjusted position with particular effectiveness.

An additional advantage is that the same cooperative axially-movable threaded means which effect the widthwise adjustment can serve to hold together the door and the mounting for the vertical pivot means, thus avoiding duplication of parts-a consideration of great importance in constructions like those under consideration where available space is limited.

In certain of its aspects, the invention further contemplates the provision of means which can be assembled and disassembled with particular case.

Arrangements embodying the invention may be employed in connection with a lower door pivot, an upper door pivot, orpreferablyboth.

While, as illustrated in my Patent 3,152,355, means have been provided for adjusting pivoted doors both in a direction parallel to the vertical edges of the doors and in a direction parallel to the top and bottom of the doors; there has remained an urgent need for the provision of simple and effective means for adjusting a door in a widthwise direction-i.e. a direction perpendicular to both of the foregoing directions. Considerations of strength, safety, and appearance dictate the operability of such means from a position outside the door.

Again, various types of pivotal mounting means for doors have been devised without taking into consideration their applicability to doors whereof the mounting means should be arranged so as to not to be easily tampered with by burglars or the like, and so as to be disassemblable only with great difiiculty as long as the door remains on its pivotal support and/or in closed and locked position. It is important, however, that considerations of simplicity,

"ice

effectiveness, and ease of assembly be not sacrificed in the provision of burglar-proof qualities.

The present invention accordingly contemplates the provision of a door-pivoting construction which, while simple, effective, and satisfactory in other respects, will satisfy all or some of the needs above indicated.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

FIG. 1 is a vertical sectional view of one form of construction embodying the invention;

FIG. 2 is a horizontal section on the line 22 of FIG. 1;

FIG. 3 is a fragmentary sectional view on a reduced scale on the plane of FIG. 2, but showing the parts in an adjusted position;

FIG. 4 is a view on the plane and scale of FIG. 1 from the opposite direction showing the top pivot of the door;

FIG. 4A is a view on the line 4A--4A of FIG. 4 showing the upper mounting for the pivot pin in detail;

FIG. 5 is a fragmentary vertical isometric view on the scale of FIG. 2 of the face of a door formed with modified portions for receiving door-mounting constructions;

FIG. 6 is a view similar to FIG. 2 showing the upper pivotal mounting of FIG. 4 in the door of FIG. 5 taken on the line 66 of FIG. 7;

FIG. 7 is a vertical sectional view showing the mounting of FIGS. 4 and 6 in a door of FIG. 5; and

FIG. 8 is a view similar to FIG. 1 showing a modified form of construction.

In the form of construction shown in FIGS. 1-4 there is provided a door 10 of conventional hollow metal (e.g. aluminum or stainless steel) construction, in association with which there are shown a lower pivot construction 11 (FIGS. 1, 2 and 3) and an upper pivot construction 12 (FIG. 4).

On the rear of the forward side 16 of the door there are provided a pair of

nuts

17 and 18 forming part of the mounting means for the lower pivot construction and providing, respectively, threaded

bores

19 and 20 and slidably engaging with each other at 21. The threaded bores extend, in parallel with each other, in a direction generally perpendicular to both the vertical extent and the widthwise extent of the door. A forward member 22 is provided with

openings

23 and 24 alined respectively with the

bores

19 and 20; and fastening

screws

25 and 26, respectively, extend thru

openings

23 and 24, and are threaded into the

bores

19 and 20. The fastening screws are formed with

heads

27 and 28 which are disposed against the forward face of the member 22 just forwardly of said openings, and the

heads

27 and 28 are formed, respectively, with means for rotating their respective screws-in the

present instance sockets

29 and 30 each adapted to be engaged by a socket wrench to turn the fastening screws.

The member 22 carries the upper element 32 of the vertical pivotal mounting for the door, and this is rotatably supported on a supporting member 33 in the form of a screw having a threaded portion 34 (fastenable into a threaded opening 35 in a floor) and a head 36. Adjustment of the screw 33 serves to raise and lower the door 10.

The

nuts

17 and 18 are formed, respectively, with in

clined thrust surfaces

37 and 38 adapted to urge the door toward and away from, respectively, the jamb 40, bearing surfaces 41 and 42 therefor, respectively, being provided at opposite edges of a rectangular opening 43 in the door. By drawing one nut (e.g. the nut 17-see FIG. 3) forwardly a desired amount after the other nut (cg. the nut 18) has been pushed rearwardly the same amount (the inclination of the

surfaces

37 and 38 being 45 in the present instance) the bottom of the door will be thrust toward the jamb, whereas the reverse of this operation will move the bottom of the door away from the jamb.

Pursuant to the invention, in certain of its aspects, the head 36 is located forwardly of the

heads

27 and 28 of the fastening screws in the path of forward unfastening movement of the fastening screws, thus interfering with the unauthorized removal of the fastening screws when the door is in place.

Since the relationship of the head 36 of the support screw to the path of forward (unfastening) movement of the fastening screws remain unchanged regardless of the adjustment of the support screw, the head of the latter will at all times render exceedingly difiicult the unfastening of one or both screws; and will thus make separation of the door and the pivotal mounting unit, and the removal of the door from a closed position, a matter of exceptional difiiculty.

A slot 47 is provided in the head 36 for operating the screw 33, and access thereto is readily had thru an opening 50 normally closed by a readily accessible screw 51 which serves in the present instance to removably retain a closure 52.

In the upper mounting means 12 there are provided, as shown in FIGS. 4 and 4A, elements similar to those of the lower mounting means 11 and similarly numbered except for the addition of the subscript a, e.g., nuts 17a and 18a and screws 25a and 26a rotatable in openings 23a and 24a, respectively in the door 10. The mounting member 55 corresponds to member 22, but is formed with an upper sleeve bearing 56 for rotary and vertical sliding movement therein of a bearing pin 57 which is mounted for vertical sliding movement in a member 58 carried by the header or lintel 59 of the door frame.

As will be seen, the bearing 56 projects downwardly into the path of removal of the screws 25a and 26a, and the bearing pin 57 blocks entry of a wrench to the sockets 28a and 29a. Further, in the present instance, there is provided a screw 60 extending from a bore 61 in the member 58 into a vertical groove 62 of limited extent in the pin 57, so that the pin cannot be removed when the screw 60 is in place. The screw 60 is accessible only when the door is open (about 90 in the present instance) and inaccessible when the door is locked closed, so as to positively prevent movement of the door by removal of the pin 57 which might enable the unhinging of the door when closed, or the movement of either of the

members

33 and 57 out of the path of the

screws

25 and 26 or 25a and 26a as the case may be. Even when the door is open, the cover 9a must be removed before the screw 60 is removed. In order to assure access to the bore 61 in either of the open positions of the door, access notches 63 are provided in the member 55.

The lintel is provided with an upright member 64 and this is secured to the member 58 by means of transversely extending screws one of which is shown in front of the other at 65, and each of which is threaded into the member 58 as at 66 and provided at its outer end with threads 67 on which a now-deformed deformable nut 68 is mounted.

I have found that, by replacing the

openings

43 and 43a in the door by recesses which extend to the lower and upper ends of the door, respectively, the assembly of the mounting means on the door as a unit can be carried out with far more ease than by putting the nuts in place after the screws have been thrust thru the openings.

Recesses

73 and 73a of this nature are shown in a door b in FIG. 5, and also in FIGS. 6 and 7 which show a construction which is otherwise similar to that of FIGS. 1-4.

In FIG. ,8 there is shown another form of construction embodying the invention in certain of its broader aspects. In this construction (which is shown in association with the upper portion of the door 10), the nuts are replaced by a plate 75 whichis fixed to the door, and one of the horizontal screws 260 is formed with an annular inclined surface 78 adapted to bear against a semi-circular bearing surface 79 on a mounting member 80 carrying a bearing 81 fitting on the vertical bearing pin 82 which descends from the lintel. The screws 25c merely serves as a holding screw, but its opening 230 is widened to permit the adjusting action, as is also the opening 240 of the screw 26c.

Since certain changes may be made in the above construction and different embodiments of the invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
