3 Claims. (01.16-51) This invention relates to door controls espe cially adapted for double doors, that is, doors that swing in opposite directions from a side of a door frame common to both doors rendering the de- -:I vice especially useful where a screen or storm door is used with a main or ordinary door of a building and may be employed on commercial or domestic buildings.
The primary object of the invention is the provision of a device of the above stated character which may be conveniently installed and will permit independent swinging of either door to closed or open position and to automatically close either door with a gradual movement to prevent slamming thereof when manually freed from a full open position, the device acting to retain the door in a full open position when so positioned manually.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which- Figure l is a fragmentary side elevation, partly in section, showing a door control constructed in accordance with my invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1.
Figure 3 is a sectional view taken on the line 3-3 of Figure 1.
Figure 4 is a sectional view taken on the line 4--4 of Figure 1.
Figure 5 is a detail sectional view illustrating a cushioning device.
Figure 6 is a fragmentary plan view, partly in section, illustrating a modified form of my invention.
Referring in detail to the drawings, the numeral indicates a door frame, 2 doors mounted on the frame I by hinges 3 so that said doors may swing open in opposite directions to each One door may be the main door of a building and the other door a screen or storm door.
comparatively long pintles 4 are rotatably supported by brackets 5 and 6. The brackets 5 are secured on the building while the brackets 6 are secured on the door frame and include relatively spaced portions 1 through which extend the pintles 4. Barrel-like members 8 are mounted on the pintles between the portions 1 of the brackets 6 and have the doors fastened thereto by straps 9. The barrels are secured on the pintles 4 and the straps are secured to the barrels so that when the door is swung the pintles will be rotated. The pintles 4, brackets B, and straps 9 secured to the barrels 8 cooperate in forming additional hinges for the door besides the hinges '3.
Curved arms II] are secured on the pintles 4 and are pivotally connected to bars II which are arranged to cross each other, as shown in Figures 2 and 3, and are pivotally connected, as shown at l2. One bar is slightly disposed in a plane above the other bar and each bar has a plurality of openings so that any one opening of a bar may be moved into matching relation with an opening of the other bar for the purpose of receiving the pivot l2 and thereby permit an adjustable connection to be had between the bars Coil springs l3 connect the bars to each other, that is, each spring is connected to one end of one bar and to an opposite end of the other bar so that when either of the doors is swung towards an open position the tension of the springs l3 will be increased and act to swing the door to a closed position when freed. When a door, as shown in Figure 3, is swung to a full open position the pivot of the arm of said door passes dead center position permitting the springs to act to retain the door in a full open position. During the opening and closing of the doors the corresponding ends of the bars I vary in distances to the other ends of said bars to bring about the varying of tension on the springs l3.
Door cushioning devices l5 are connected with the ends of the bars to parallel the springs l3 and each consists of a cylinder Hi to receive a liquid and operating in said cylinder is a piston consisting of a substantially conical shaped hollow piston head l8 and a hollow stem IS. The stem l9 extends through one end of the cylinder. The
cylinder is connected to one end of one of the bars and the stem of the piston is connected to an opposite end of the other bars. A comparatively large port is formed in the end of the piston head and a small port 2| is formed in the stem I9. A series of ports 22 is provided in the head between the ports 20 and 2|. A spring pressed valve element 23 shaped to fit the piston head operates therein and has a passage 240i a diameter approximately of the same diameter as the port 2|. Normally the valve element closes the ports 22 by the action of the spring 25 so that the flow of liquid from one side of the piston to the other in the cylinder is by way of the ports 20, 2| and passage 24 checking the movement of the piston in the cylinder and consequently checking ED STATES PATENT OFFICE the movement of the door towards closed position, permitting the door to close gradually without a slam. However, the movement of the piston in an opposite direction by the door swinging open, the flow of fluid will then be through the ports 22 unseating the valve element and port 20 allowing a more rapid flow of fluid from one side of the piston to the other.
Instead of employing a pair of cushioning devices l5 as shown in Figures 2 and 3, a single cushioning device 21 constructed similar to one of the cushioning devices I5 may have the cylinder thereof pivoted to rods 28 while the stem is pivoted to rods 29. The rods 28 and 29 are pivotally connected to links 38. The links 30 are pivotally connected to ends of the rods ll. With this arrangement the single cushioning device 21 performs the same function as the pair of cushioning devices H5.
The stem IQ of the piston I! has slidable therei in a plunger 3! and the latter has a stem 32- extending outwardly of the hollow stern of the piston and having threaded a connection therewith and equipped at its free end with a finger piece 34. By rotating the finger piece 34 in opposite directions theplunger 35 may be adjusted relative to the port 2! for the purpose of varying the size of the port and consequently the tension springs connecting said bars.
2. Door controls comprising pintles, means connecting said pintles to hingededges of doors and to a door frame, arms secured on said pintles, pivotally connected bars crossing each other and pivotally connected to said arms, tension springs connecting 'said bars, and door cushioning means connecting said bars.
3. Door controls comprising pintles, means connecting said pintles to hinged edges of doors and to a door frame, arms secured on said pintles, pivotally connected bars crossing each other and pivotally connected to said arms, tension springs connecting said bars, links pivotally connected to said bars, pairs of rods pivoted to said links, and a cushioning device having one end connected to one pair of rods and its other end connected to the other pair of rods.
