This invention relates to a door construction of the type called balanced and panic door.

An object of the invention resides in the provision of a structure in which the parts are so constructed and arranged that the door will'have a pivotal movement and a movement of translation when acting as a balanced door, and will have a swinging movement about a single pivot ment of parts described in the specification, il-' lustrated in the drawings and recited in the. claims.

In the drawings, which illustrate an embodiment of our invention:

Figure 1 is a fragmentary view of the top portion of the door and doorway;

Figure2 is a fragmentary view of both the top and bottom portions of the door and doorway;

Figure 3 is a horizontal sectional view on the line 3-3 of Figure l;

a Figure 4 is a horizontal sectional View on the line 4-6 of Figure 2; and

Figure 5 is a vertical sectional view on the line 5-5 of Figure 1.

In the embodiment of the invention illustrated inthe drawings the upper and lower rails of the door are indicated by the reference numerals! and 2, and the stiles by the reference numerals 3 and 4. The head of the doorway is denoted by the reference numeral 5, and the jambs by the reference numerals 8 and 1.

Referring, now, particularly to Figure 3, it will be seen that the jamb 6' has inner and outer facings Sand e, and'an arcuate facing or member If) adjacent which is located a door coordinating element.

This coordinating element H is provided with an arcuate wall or member I2 which is struck on substantially the same arc as the member Ii of the jamb 6 is nested therewith, and is also provided with an extension l3 which projects toward the door. A weather sealing strip [4 projects fromthe coordinating element to seal the space 10 Claims. (Cl. 20-16) between the coordinating element andthe'stne- 3 of the door.

We have illustrated the coordinating element as being formed-oi hollow sheet metal, but it is to be understood that this element may be other'--.

wise formed, as for instance as a solidelement,

At the upper end ofthe-coordinatingelement; a door supporting arm i5 is made rigid with-the" coordinating element, and projects into a-recessi l 5' in the upper rail of the door; the-recessopen= ing'throu-gh the outer face,- oniy, of therail; --At its end.- the arm is pivotedat lfinto-the upper rail Ii:

A corresponding arm i'l isrigid with the lower endof the coordinating element and lieswithin a-recess ii" in the outer face of the lower rail-of:

the door and is pivoted thereto, at is, in align ment with the pivot l6.

Apivot pin I53, havin ahead 22 on the upper end: thereof, is rotatably'mountedin, and-supported by, a thrust bearing 23- andlateral bearings it in the head Set the doorway; This pivot pin is is slida oly and adjustably engaged'in an;

opening in the upper arm 55-. A nut tuengaged with the lower end of. the pivot pin l9 andlocatedin a recessin the'arm 5; makes it: possible toarljust the door up-weirdlyor downwardlyon tnepivot i9, as theoceasion requires. Set

scr JS 2.: are providedfor maintaining the doorand the pivot pin in their relative adjusted positions.

The lower arm liis. provided with a recess in common pivot center the vertical axis of the pivot pin and the door check lug 25 andthe distance.

between the outer curved face of the member [2 and the axis of rotation of the arms [5 and I1 is such that when the door is swung as a panic door on a single pivot .to an open position, i'. e.,'

a position normal to the closed pQsi-tion,-the door and the arms will lie beyond the adjacent ends of the wallet and 9 of thejamb 6 as indicated in dotted lines in Figure 3.

Thus when force is applied to the inner; face I of the'door adjacent both of the stiles,-the door and the supporting arms will be swung outwardly about the vertical center'of the pivot pin I9 and the lug 25 and only about this 'pivot'sincethe re--' cesses in which'the arms-arealocatedropen only;

- The. curvedzmembers ll} and I2. of the :doorf, jamb 6 andthecoordinatorelement have-as theirv through the outer faces of the upper and lower door rails.

A door of this construction may also be combined with such a balanced door mechanism and panic mechanism as illustrated in the Ellison Patent No. 2,019,528, dated November 5, 1935, and thus incorporated in a balanced and panic door.

In such a construction the guide pin 28, which is provided with a roller 29, is carried by the panic arm 30 which is pivoted at 3| to the door and is normally held rigid with the door by the panic latch '32, as described in said patent. This guide pin 28 slides in a guideway in the head 5 when the door moves to an open position as a balanced door. In such movement there is of course a pivotal movement about the guide pin 28, a movement of translation with the guide pin, and there is also a pivotal movement of the arms about the axis of the pivot pin [9 and a relative pivotal movement about the axis of the pivot l6 between the upper and lower supporting arms l5 and I1 and the door.

It will be noted that the ends Of the arms l5 and I1 are provided with enlargements such as shown at 21 in Figure 4 of the drawings, and these enlarged ends are of the cross sectional configuration of the coordinating element H, with the'result that the appearance of the coordinating element will be substantiall the same throughout its length.

' While we have illustrated and described a particular embodiment of our invention, the art will understand that certain details of construction may be changed without departing from the spirit of the invention or exceeding the scope of the claims.
