64 JOHN P. TANSEY v(A/1.14 M

United States Patent 3,292,204 DOOR AND HINGE. COMBINATION John P. Tansey, Dunedin, Fla., assignor to The Tansey Company, Pinellas, Fla., a corporation of Florida Filed Feb. 5, 1964, Ser. No. 342,759

Claims. (Cl. 16-153) This invention relates to partitions and, more particularly, to doors in combination with partitions and hinges in combination therewith for use in rest rooms and the like.

Doors according to prior designs usually were made in such way that unauthorized persons could remove some of the fastening structure and dismantle the doors.

The hinge disclosed herein makes it almost impossible for an unauthorized person to dismantle the door without knowing the combination of steps necessary to dismantle the door. If a child locks himself in a rest room booth and crawls out of the booth, with the ordinary design of lock, it is necessary for some one to crawl under the door to unlock it. With the hinge design disclosed herein, the door can be lifted up bodily to unfasten the latch.

The hinge disclosed is also extremely easy to assemble; however, if a child in a school removed a nut with pliers, the unit would not come apart but would continue to work. Gravity would hold the hinges together. The child would have difliculty taking the door apart unless he knew the combination of assembling steps.

It is, accordingly, an important object of the present invention to provide a hinge in combination with a door and partition wherein the hinges are inset in the door at positions spaced from the top and bottom of the door.

Another object of the invention is to provide an improved hinge in combination with a door.

Still another object of the invention is to provide a door, hinge, and latch combination wherein the hinge is constructed in such a manner that the door can be disconnected from the latch by lifting the door bodily a sufficient amount of allow the door and latch to be disconnected.

A further object of the invention is to provide a plurality of hinges in combination with a door wherein the hinges will have a cam action to close the door.

Still a further object of the invention is to provide a hinge in combination with a door which is simple in construction, economical to manufacture, and simple and efiici'ent in operation.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. 1 is a partial side view of a door and hinge combination according to the invention;

FIG. 2 is an exploded view of the male cam, female cam, pin and nut combination according to the invention;

FIG. 3 is a partial view of the door and latch combination; and

FIG. 4 is a cross sectional view of the cam member taken on line 4-4 of FIG. 1.

Now with more specific reference to the drawing, a door 60 is shown having .a top hinge 16 and a bottom hinge 21 thereon. Both the top and bottom hinges are identical in construction. Each hinge 16 and 21 is made ice up of a hinge member 23 which is attached to a pilaster 24 by means of a sheet metal screw or bolt 17 with a laterally extending bracket member 25 extending into a notch in the door.

The door 60 is of a suitable size and construction. It may be made of two parallel, spaced, sheet steel side panels of the type commonly used in modern construction. The door 60 has two vertically spaced notches 22 therein adjacent the rear end which terminate at the rear end. These notches each receive one of the escutcheons 20. The escutcheons 20 are secured to the door by means of screws or pop rivets at both sides at 120. The escutcheons 20 may be die cast, fabricated, or of any other suitable construction.

The hinge is made up generally of six parts; namely,

the hinge member 21, the escutcheons 20, a female hinge cam member 10, a male cam member 12, a pin 13, and a nut 14. The hinge as Well :as the escutcheons may be made of a die casting.

The pin 13 has an intermediate enlarged cylindrical portion 39, a reduced size top cylindrical portion 31, and a rectangular shaped door portion 32 terminating in its lower end in a partial threaded portion 33.

The male cam member 12 has a cylindrical upper portion 40 with a cam surface 39 on its upper end. It is hollow. The upper part of the hollow therein is of cylindrical shape and of complementary shape to the enlarged cylindrical portion 30 of the pin 13. A lower part 41 of the hollow portion in the male cam member 12 is square and it receives the portion 32 of the pin. The outside of a lower portion 40 of the male cam member 12 is square and it has a cylindrical hole 42 which receives the threaded portion 33 of the pin 13.

The female cam member 10 has a tapered upper outer surface 15 which is rectangular in cross section. The female cam member is received in a bore 45 of the escutcheon. The square shape of the female cam member 10 prevents the cam member from rotating when the door is opened and closed. The female cam member 10 terminates at its lower end in the outwardly extending flange 44 which, in practice, rests on the upper surface of the bnacket 25 and forms a bearing surface thereon. Male cammember 12 may be made of nylon or some other self-lubricating material to prevent noises as flange 44 rides on bracket 25.

The hollow of the female cam member 10 has three cylindrical surfaces of different diameter. These arethe cylindrical portion 35 which is complementary in shape to the outer cylindrical surface 40 of the male cam and the male cam is received in it. This large cylindrical portion joins with the intermediate cylindrical portion 36 which is of complementary shape to the cylindrical portion 30 of the pin 13. The upper end of the female cam has the bore 37 which is complementary in shape to the reduced size portion 31 of the pin 13. Nut 14 fits on pin 13.

The downwardly disposed cam surface 28 in the female cam member 10 defines the bottom of the cylindrical bore 35 and this is complementary in shape to the cam surface 39 of the male cam member 12. a

- The square end of the male cam fits into a star shaped counter bore 45 in the bracket 25. Thus, cam 12 can be positioned selectively in a plurality of positions.

The escutcheon 20 may be of die-casting metal and has two continuous flanges with a flat bottom therein and having a generally flat bottom rests against the part of the metal door which defines the notches 22 and the flange around the edge of the escutcheon locates the escutcheon in the door. The escutcheon is U-shaped in cross section and the flanges and bottom form a continuous channel.

The hole 26 formed in the bottom of the escutcheon is open during assembly and closed by the bracket 25 which has the teeth on it that holds it in position. This is merely to close the hole and form a neat appearing device.

The clearance between the lower end of the threaded portion 33 and the top surface of the closure is equal to or slightly larger than the thickness of the bracket 25 so that the bracket can be slid under the threaded member 33 when the device is assembled.

The door may be held in place by means of the door latch portion 160 which is fixed to the door and the fixed latch portion 61 which is fixed to the pilaster 62. The notch in the member 61 is slightly less in depth than the space between the end 33 and the escutcheon25' so that the door can be lifted to unlatch it'if necessary.

To assemble the door, it is only necessary to first, slip' one door escutcheon 20 into each of the top and bottom notches with the escutcheon flanges laying along side the door secured to door with a screw or pop rivet, and then slide in and press the female nylon cam 10 up into the rectangular hole 110. Female cam member 10 has a press fit in hole 110 so that it supports its own weight and then stays during assembly. An important feature is that the female cam member stays in the escutcheon until the hinge is assembled.

Pin 13 is then inserted thread end downthrough the female cam member into the hole. The male cam is then laid horizontally on the bottom of the escutcheon. It is moved over the threads of pin 13 and up into the bore 35 in the female cam member. The escutcheon 25 is inserted into the hole 26 so that the entire assembly cant fall down into the hollow of the door and be lost temporarily.

The door may then be attached to the pilaster by merely setting the end permitting the pin 13 and end .40 to drop into the star lock counterbore 45 in bracket 25. The door may be swung to full open,full closed, or part open position.

The door may be lifted, for example, approximately one-fourth of an inch to release the latch.

The foregoing specification sets forth the invention in its preferred practical forms but it is understood that the structure shown is capable of modification within arange of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
