INVENTOR. JOHN P TANSEY United States Patent 3,147,831 D0011 HINGE STRTKITURE John P. Tansey, Dunedin, Fla, assignor to The Tansey (Iornpany, Tarpon Springs, Fla, a corporation of Florida Filed June 19, 1962, Ser. No. 203,547 1 Claim. (Cl. 189-46) This invention relates to doors and, more particularly, to improved hinges in combination with doors.

Doors for toilet partitions and the like require hinges which will automatically return them to closed position. These hinges should be neat in appearance and either the hinge should be invisible or the hinge structure should blend in with the door and partition structure.

It is, accordingly, an object of the present invention to provide an improved hinge and door combination.

Another object of the invention is to provide a hinge and door combination which is simple in construction,

economical to manufacture, and simple and efiicient to install.

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 drawings and more particularly pointed out in the appended claim, it being understood that changes may be made in the form, size, proportions, and minor details of construction Without departing from the spirit of sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is a view of the upper rear corner of a door and hinge according to the invention;

FIG. 2 is a cross sectional view taken on line 2-2 of FIG. 1; and

FIG. 3 is a view of the lower rear corner of the door.

Now with more particular reference to the drawings, a door 16 is shown connected to a pilaster 17 by means of the two hinges shown.

The pilaster 17 may be made of suitable construction such as fabricated enameled steel or painted steel. The door 16 will be made of two laterally spaced

sheets

29 and 30. The

sheets

29 and 30 are connected together at the top by a top plate 35 and a similar plate 36' which extends up along the rear edge of the door 16 and a plate 37 which extends along the bottom.

Upper strut retainers 22 and 22' are in the form of spaced plates spacer above a top cut-out notch 32 which receives an escutcheon 11. Vertical struts 36 are made of similar plates and they extend from the strut retainer 22 vertically of the door 16 and may terminate at an intermediate position therein. A similar cut-out notch is cut in the lower edge of the door and it receives a lower escutcheon 14. The escutcheon 14 is held in place by a screw 12 which extends through the escutcheon and into a vertical strut 15. The vertical strut is similar to the struts 36. The strut 15 extends from a strut 18 to the plate 37 of the door.

The door 16 is supported on the pilaster 17 by means of the two hinges having brackets shown. The upper hinge has a bracket 13 which is connected to the pilaster 17 by screws 18. The hinge has spaced legs defining a U-shaped part which receives the edge of the pilaster and a bracket which extends into the space between the legs of the escutcheon 11. The bracket 10 has a flat top and bottom surface as shown.

The escutcheon 11 has spaced legs defining the U- shaped part. A flange on each side of the leg overlaps the sides of the door adjacent the cut-out. The escutcheon 11 is held in place by a screw 26 which extends therethrough and into the nearest strut 36.

ice

A pin 21 extends through aligned holes in the struts and in the legs of the escutcheon 11 as well as through the holes in the bracket 10, washers 24, and a rubber cylinder 25. The washers 24 sandwich the rubber cylinder 25 therebetween. The bottom washer rests on the lower leg of the escutcheon while the upper washer 24 rests against the lower side of the hinge bracket 10. The head of the pin 21 rests against the top of the upper strut retainer 22 when in operative position. A cotter pin 23 is put through a hole in the pin 21 when the pin is in assembled position to hold the pin in place. It will be noted that the upper strut retainer 22 is spaced below the upper edge of the door an amount equal to the opening between the escutcheon legs so that the pin 21 can fall up against the upper end of the door when the door is inverted and provide a space to insert the hinge bracket 10 therein and thus permit assembly.

A lower hinge 33 is held on a pilaster by means of screws 34. The hinge 33 has a bracket 37' which extends into a cut-out 31 and into the leg between the escutcheon 14. The escutcheon 14 is similar to the upper escutcheon 11 and it has spaced legs with the overlying flange which receives the door. The lower escutcheon 14 is held in place by the screw 12 which extends through the escutcheon and into the strut 15.

A pin 20 has a cam 19 fixed thereon. The cam 19 is cylindrical and has a cam surface on one end. A hole 38 in the lower put of the escutcheon 14 is large enough that the cam 19 can pass through it and up through a similar upper hole therein.

In operative position, the pin 26 is in the position 20' and the cam 19 is in the position 19 with a boss 35 resting in a non'circular counterbore in the bracket 3'7 and its cam surface in engagement with a cam 48. A threaded part 49 of the pin 21) extends through a hole in the bracket 37 and is locked therein by a nut 27.

To assemble the door 16 to the pilaster 17, it is merely necessary to slide the pin 21 up into the door above the cut-out 32. Then the top escutcheon 11 is pressed into the cut-out or notch 32. The escutcheon 11 is then secured to the door 16 by means of the screws 26. The threaded part of the pin 21 may then slide down through the washers 24 and the rubber cylinder 25. The cotter pin 23 may then be inserted to secure the pin in position.

The lower pin 20 and cam 19 can be inserted into the door cavity below the notch 31. The bottom of the door escutcheon 1 2- can then be pressed into position with the hole therein aligned with the hole in the strut 18. The escutcheon can then be attached by means of screw 12 which will threadably engage the strut 15. The hinge bracket 37 can then be inserted into the notch 31. The door can then be inverted to an upright position and this will allow the non-circular boss 39 to drop into the counterbore in the hinge bracket and the nut 27 can then be tightened. Thereafter, the cover 28 can be placed in the hole 38 to fill it. The cover 28 is of the conventional type made of a round sheet metal disk having the legs shown which will underlie the material in the hole which receives it and hold it in position.

To adjust the door 16, it can be moved to a forward position or to a closed or partially open position and the nut 27 backed off. The door can then be lifted and the pin 20 rotated and reset in the noncircular counterbore of the retainer hole in the bracket 37'. Then the nut can be tightened.

The nut is not required to make the unit work. If in a school or similar establishment, this is removed and the door would continue to work without the nut.

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

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

A door and hinge combination, said door being made of two laterally spaced sheets of material, a notch cut out of said sheets at one edge thereof adjacent the top thereof and another notch cut out in the same edge adjacent the bottom thereof, two spaced top struts in said door between said sheets and slightly above said top notch and extending from one said sheet to the other, two escutcheons comprising generaliy U-shaped members one fitting into each said notch, each said escutcheon having a flange on each side thereof overlying said sheets around the margins of said notches, a top and a bottom hinge, said hinges having brackets, one said bracket extending into each said notch, aligned holes in the top said escutcheon, a top pin extending through said struts, said bracket, and said escuteheon holes, said pin having a head resting on the top said strut, a resilient member, a cotter pin disposed in said pin between said bracket and said escutcheon, and means to secure said 4 bottom bracket to said door and to raise said door when said door is opened, compressing said resilient member, a cotter pin disposed in said pin between said bracket and said escutcheon, preventing said pin from moving upward, said pin being free to fall toward the top of said door and out of said bracket when said cotter pin is removed and said door is inverted, two s aced bottom struts disposed between said sheets above the bottom said notch, said means to secure said bottom bracket to said door comprising holes in said escutchcon, said bottom bracket and said bottom struts having holes all aligned with each other, means having a hole therein and a downwardly facing cam surface thereon attached to said lower strut, a bottom pin extending through said holes in said bracket, said cam means, and said holes in said bottom struts, and a cam member on said pin engaging said cam surface, said pin being locked to said bracket.
