INVENTOR. JULIUS REITER ATTORNEY United States Patent Ofiice 3,011,779 Patented Dec. 5, 1961 3,011,779 CONTROL FOR A DOOR AND DGQR 1N CGMBINATION THEREWITH Julius Reiter, 2617 Pennsylvania Ave, Erie, Pa. Filed May 8, 1959, Ser. No. 811,985 2 Claims. (Cl. 268-62) This invention relates to double doors and, more particularly, to devices for operating such doors.

Storm doors which are made according to common practice for use as an auxiliary door to prevent cold air from coming in contact m'th the ordinary door on a dwelling house are usually in the form of a single door panel hinged at one side. This door panel is easily caught by the wind as it is opened and, therefore, is likely to become damaged. Further, it is difiicult to provide a snfiiciently strong hinge structure for a storm door of the usual type because it is usually desirable to use a large glass area therewith.

According to the present invention, two separate door panels are hinged to the door jamb, one at each opposite side, and spaced outwardly only three or four inches from the regular door. The closing mechanism which operates the door folds into a compact arrangement in the narrow space between the storm doors and the regular door. With the device disclosed herein, when one of the doors is manually opened, the other door will automatically open and because of the improved structure of the linkage mechanism, the mechanism will fold into a very narrow space.

It is, accordingly, an object of the present invention to overcome the above and other defects in present storm doors and, more particularly, it is an object of the invention to provide an improved storm door mechanism which is simple in construction, economical to manufacture, and simple and eificient to use.

Another object of the invention is to provide an improved door operating mechanism.

Another object of the invention is to provide an improved storm door and mechanism therefor.

A further object of the invention is to provide an improved operating mechanism for double doors wherein the mechanism will fold into a narrow space between the doors and outer doors.

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 bottom view of the doors and closing linkage according to the invention;

FIG. 2 is a bottom view of the device shown in FIG. 1 with the doors in open position; and

FIG. 3 is a view of the storm doors taken from the side thereof adjacent the building.

Now with more particular reference to the drawing, two doors 11 are supported in door jambs 12 which form the frame for the doors 11. The doors 11 are hinged to the door jambs 12 by means of hinges and a header 13 forms a top for the door frame. One of the door knobs 14 is attached to each of the storm doors 11.

The linkage or operating mechanism is made up of a short link 21, a long link 29, and a control link 19. The short link 21 and the long link are connected together by means of a rivet or screw which fits into a hole in the link 21 and into a slot 22 in the link 25. The slot 22 will ordinarily be between onehalf and five-eighth inch long. The other end of the link 20 is pivoted to a bracket 17 and the bracnet 17 is fixed to an intermediate part on the doors 11. A bracket stop 24 is bent from a bracket 18 downwardly at a right angle to engage the link 20 when the left door 11 starts to move. Thus, using the left door 11 as the control door, it will move slightly open and a flap 27 will engage the right door 11 and force the right door 11 to open with it.

The flap 27 is attached to the right door 11 and extends laterally to engage the left door 11. The flap 27 is formed in an inwardly extending arc. The right door 11, when used as the control door, will open and the flap 27 will cause the left door 11 to open. 7

The short link 21 is pivoted to the bracket 18 which is in turn fixed to the right door 11 and then pivoted to control link 19 by means of a pin 23. The other end of the link 19 is pivoted to the header 13 by means of a pin 26 and a socket member 16 is fixed to the header 13 and overlies the link 19. The socket member 16 forms both a stop and a support for the link. The socket member 16 is wider at one end than at the other as shown. The socket member 16 is U-shaped in cross section and V-shaped as shown so that the side edges of the slot for-m limit stops for the link 19.

When the doors 1-1 are closed as shown in FIG. 1, the links will be folded together in a vary narrow space between the inner door and the storm doors. The control link 19 will rest against the inner end of the socket member 16 and the rivet 25 will he in the remote end of the slot 22. When the doors 11 are open, the rivet 25 will move to the other end of the slot 22 and then to the end shown as the doors 11 are further moved to the open position.

By providing the slot 22 in the link 20, the links can be made to fold to the position shown and by providing the bracket stop 24 on the bracket 18, the doors 11 will be forced to operate together.

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 claims.

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

I. In combination with a building having a door opening defined by jambs, door members mounted on opposite sides of said opening between said jambs to swing thereon, a short link connected to one said door member and a long link connected to the other said door member, said links being connected together at their distal ends by means of a pin disposed in a hole in said short link and in a slot in said long link, and a control link having one end pivoted to an intermediate part of said short link and the other end of said control link connected to the header of said jambs, and stop means fixed to said jambs engaging one of said links when said door members are closed, causing said pin to slide in said slot and said long link to move relative to said short link and moving said links into the space between said jambs.

2. In combination with a building having a door opening defined by jambs, door members mounted on opposite sides of said door opening to swing on said jambs, an inside door on said building spaced from said door members, a short link connected to one said door member and a long link connected to the other said door member, said links being connected together at their distal ends by means of a pin disposed in a hole in said short link and in a slot in said long link, a control link having one end pivoted to an intermediate Part of said 7 4 short link and the other end of said control link conin open position and for said control link when said door nected to the header of said jambs, and a socket mernmembers R in 6 0 661 PQ iti n.
