WEATHER STRIP.

Application filed. May 16, 1923.

T0 aZZ whom it may concern Be it known that I, AUeUs'r A. L'UNDEEN, a citizen of the United States, and a resident of the city of New York. borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Weather Strip, of which the following is a full, clear, and exact description.

This invention has relation to weather strips and has particular reference to a weather strip for doors, windows or other swinging closures, the principal object in view being to provide means for sealing the lower edge of the closure when in closed position, against the entrance of the elements.

As a further object the invention contemplates a weather strip for sealing the lower edge of a swinging closure against the entrance of the elements which is automatically operable by the swinging of the closure to closed position to seal the lower edge and which further operates upon opening of the closure to swing the lower edge of the strip upwardly to an out-of-the-way position whereby the same will clear the threshold of a door, bead of a sill or other similar obstructions.

As a still further object the invention contemplates a weather strip of the character set forth which is extremely simple in its construct-ion, readily applicable to a door, window or other swinging closure, and which is highly efficient in its purpose.

With the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claim is expressed.

In the drawings- Figure 1 is a fragmentary front view of a swinging closure and closure frame equipped with a weather strip, in accordance with the invention and illustrating a closure in closed position.

Serial No. 639,374.

Fig. 2 is a bottom plan View of the same with the closure partially opened.

Fig. 3 is a perspective view with. the closure partially opened.

Fig. 1 is an enlarged fragmentary cross sectional view taken approximately on the line 414 of Fig. 1.

Referring to the drawings by characters of reference A designates a swinging closure such as a door, window or the like, B the side rail of the frame and C the sill or other rail of the frame. The weather strip structure constituting the invention includes an attaching rail 10 which is secured transversely of the closure A in parallel spaced relation to its lower edge by screws or other fastening elements 11 which pass through the attaching rail and are anchored in the closure. The lower edge of the attaching rail is provided with a depending bead 12 and the weather strip member 13 is attached to the under side of the attaching rail by hinges 14 which are concealed by the head 12. The means for actuating the strip member 13 to effect swinging movement of the same consists of a rod 15 mounted for transverse movement in bearings 16. The coiled expansion spring 17 surrounds the rod 15 and bears at one of its ends against the intermediate bearing 16, the opposite end engaglng with a pin or other suitable abut- Inent 18 carried by the rod 15 whereby one of the extremities 19 of the rod is normally projected beyond the side face of the closure which abuts the side rail B of the frame when the closure is swung to closed position. A connection consisting of a link 20 is established between the rod 15 and the strip member 13 which serves upon movement of the rod 15 by the spring 17 to project the extremity 19, to cause the strip member 13 to be swung on its hinges at an angle with relation to the closure. The projecting extremity 19 further operates upon closing of the closure to move the rod 15 in the opposite direction against the action of the spring 17 by engagement of the extremity 19 with the side rail B of the frame. This movement exerts a pull on the link 20 and swings the strip member 13 downwardly to a substantially vertical position whereby the yieldable gasket strip 21 projecting from the lower free end of the strip member 13 is impinged into sealing contact with the upper face of the sill C. Upon opening the door, the initial movement permits the spring 17 to effect the projection of the extremity 19 of the rod whereby a push is exerted on the link 20 to swing the strip 13 upwardly and at an angle to the closure whereby its lower edge is elevated to clear any obstruction such as a threshold 1) or head of .a sill. A shield consisting of a base plate 22 secured to the inner face of the side rail B by fastening elements or screws 23 is provided adjacent the lower corner and said plate is formed with a flange 24: which overlies and covers a portion of the attaching rail 10 and an inwardly spaced flange 25 is further provided on the plate in front of which the end of the weather strip member 13 lies when the door is in closed position. The base plate serves as a protecting surface with which the projecting end of the actuating rod engages upon closing the door. It is, of course, understood that the device is applicable to double swinging closures as illustrated in Fig. 1, or swinging closures of the single type without alteration to the con struction or mode of operation.

I claim:

The combination with a door frame and a hinged door thereon, of a weather strip hinged to the door adjacent its lower end, a sliding and spring pressed rod having one end projecting beyond the door when the door is open, means connecting the rod with the weather strip whereby in one position of the rod the weather strip will be held in an inclined position and in the other position of the rod, the weather strip will be swung downwardly, and a protecting plate on the door frame with which the projecting end of the rod engages when the door is closed, to operate the said rod for swinging the weather strip downwardly, said plate having a curved flange which overlies the end of the weather strip and a straight flange below the curved flange with which the weather strip abuts when the door is closed.
