Application November 13, 1958, Serial No. 391,825

1 Claim. (Cl. 20-16) This invention relates to improvements in door closer assemblies.

The object of the invention is to provide a more practical and eflicient door closer assembly which limits the angle to which the door may be opened and which will close the door automatically when the opening force is withdrawn.

Another object of this invention is to provide a door and closer assembly in which the mechanism occupies relatively small space and is completely contained Within the door opening when the door is closed.

A further object of the invention is to provide a door and closer assembly which is of simple and inexpensive construction, is easily installed and is sturdy and dependable in operation.

Other objects and advantages of the invention will appear in the ensuing description considered in conjunction with the attached drawing in which:

Figure 1 is a fragmentary elevational view of adoor frame and a door showing the present invention, the door being in the closed position;

Figure 2 is a view of the assembly of Figure 1, taken along the line 22 of Figure 1; and

Figure 3 is a view of the assembly shown in Figure 2, with the door in open position.

Referring now to the drawings in more detail, numeral 1 designates generally a door frame, having spaced

side jambs

2 and 3. lamb 2 is provided with a longitudinally extending notch 4 cut out from its inner face adjacent one edge thereof. A door 5 is positioned within the space between the

jambs

2 and 3 and has one edge hingedly connected to the jamb 3 adjacent the edge complemental to the edge of jamb 2 in which notch 4 is cut, for opening and closing movement with respect to the space between the

jambs

2 and 3. v

Operatively connected to the door 5 is a door closer 6. The closer6 consists in part of two straight rigid arms 7 and 8 arranged in partially overlapping end to end relation. The arm 7 is somewhat shorter than the arm 8. The arms 7 and 8 are connected at their overlapping ends for pivotal movement about an axis transverse of said arms by means of a bolt 9 extending transversely through said overlapping ends and threadedly engaged by a pair of nuts 10. A washer 11 is positioned upon the bolt 9 between the overlapping ends of the arms 7 and '3 to facilitate their movment with respect to each other.

The other end of the arm 7 is hingedly connected to the inner face of the door 5 adjacentthe edge of the door opposite to that at which the door is hinged to the jamb 3, as shown at 12. The other end of the arm 8 is hingedly connected to the inner face of the jamb 2 inwardly of the notch 4, as shown at 13. When the door has executed its closing movement, the portion of the door adjacent its 2,769,213 Patented Nov. 6, 1956 side opposite to that at .which it is hinged, seats in the notch 4.

The other part of the closer 6 consists of a coil spring 14 having one end connected to the arm 7 by means of an extension 15 which is angulatedtoward the door frame '1, and the other end connected to a hook 16 which is fastened in the frame 1 inwardly of the hinged connection 13, the spring urging the door to its closing movement position.

From the foregoing, it will be seen that when the door 5 is in itsclosed movement position, the arms 7 and 8 will be in a substantially side by side position and the spring 13 will be in a relatively contracted position, as shown in Figure 2. When the door is opened, the arms 7 and 8 will pivot with respect to each other to an end to end position, as shown in Figure 3, in which position they will prevent further opening of the door. As the arms 7 and 8 move toward their end to end position, their pivot, bolt 9, to which one end of the spring 14 is also connected, moves away from thehook 16 and the spring is extended. Thus, when the opening force is withdrawn from the door 5, the spring 14 will contract drawing the bolt 9 toward the hook 16, returning the arms 7 and 8 to their substantially side by side position and closing the door. When the door 5 reaches the closing movement position, as shown in Figure 2, the free side seats in the notch 4 preventing further closing movement of the door. In the closed position, as also shown in Figure 2, the closer mechanism lies entirely within the space between the

jambs

2 and 3.

It is obvious that the angle at which the opening of the door will be stopped by the mechanism of the present invention may be varied by varying the lengths of the

arms

6 and 7. It is also obvious that the vigor of the closing movement supplied by the mechanism may be varied by varying the tension of the spring 14.

What is claimed is:

In combination, a door frame having first and second jambs, said jambs having forward edges, a door having an outer edge and inner edge, said inner edge of the door being hinged on the forward edge of said first jamb, a first straight arm having inner and outer ends, the outer end of the first arm being pivoted to the door at a point intermediate the edges of the door, a second straight arm having outer and inner ends, the outer end of said second arm being pivoted to said second jamb at a point spaced rearwardly from the forward edge of the second jamb, means pivoting the inner ends of said first and second arms together, a lateral extension on the inner end of said first arm projecting in a direction away from the door and toward said jambs, and a contractile spring stretched between said extension and a point on the door frame adjacent to said second jamb and spaced rearwardly from the pivoted connection of said second arm with said second jamb.
