WEATHER STRIP.

v Application flied June 20, 1925. Serial No. 38,570.

To all whom it may concern:

Be it known that I, Orro H. PETERSEN, a citizen of the United States, residing at Oakland, in .the county of Alameda and State of California, have invented certain new and useful Improvements in eather Strips, of which the following is a specification.

My invention relates in general to weather strips, and more particularly to such strips for securement to the bottom edge of the door, to close the gap betwen the bottom of the door and the surface of the floor and check the blowing of the wind therethrough.

Outside doors generally have thresholds, but in present constructions thresholds for inner doors are being eliminated so that the floor surface will be uninterrupted and continuous from room to room. Hall runners, rugs and carpets are now commonly seen extending from room to room, hence one reason for the omission of the threshold. Since the omission of the threshold the door has not been made longer, as the door in swinging must still clear thecarpets, but when the door is closed and no carpet or the like is extended through the doorway the blowing of the wi 1d through-the former threshold space is not checked, and during certain times and seasons of the year this wind is annoying and objectionable due to the cold draft one encounters. Therefore, my primary objects are to check the draft and thereby exclude the cold and wind by means attachable to the bottom of the door, and which means not only close the clearance space between the door and floor but also allows the door to swing with ease over any floor covering about the doorway.

Another object is to form the closing member with a plurality of portions adapted to hinge or bend simultaneously in proportion to-the stress exerted at such portions when the door is swung in either direction over a floor or the covering therefor, so as to permit the head portion of the member to move to and fro without causing a binding action thereof between the door edge and the floor or said covering.

A further object is to allow the closingv member when worn to be easily replaced in the holding member by a new one.

With the above and other objects in yiew, my invention consists of two simple and inexpensive members, ,a holding member and a closing or active member. The accompanying sheet of drawings will exemplify the present construction of the invention and in which: u

Figure is a face View of a door having my Invention applied thereto; and Figure 2 is an enlarge view of the lower righthand corner thereof.

Figure 3 is a side edge View of Figure 2 show ng the invention in normal unstressed posit on; and Figure 4 is a similar view but showmg the active member stressed and in slid ng engagement over a rug.

Figure 5 is a plan of a portion of the active member; and Figure 6 is an end view of the same. I

Figure 7 is a plan of a portion of the holding member; and Figure 8 is an end view of the same.

I will now describe the figures in detail by reference numerals and in which, 9 indi-- cates a conventional door, and 10 the bottom edge thereof and 11 the surface of the floor and from which the door is hung in suspension a fixed distance, usually five-eighths of an inch. This distance is generally sufficient to allow the door to swing over and clear the familiar carpet, rug or equivalent floor covering 12 beneath the door or within the range of the same when swung open.

- The invention per se consists, in this case,

of a holding or retainer member 13 of selected sheet metal or the like and a strip of flexible material 14 preferably of a suitable grade of rubber.

The retainer member is a strip of plate having its longitudinal ed es struck up and over towards the center 0% the web 15 and forming thereby a channel plate having curved resilient flanges 16 opposed to and spaced from the web 15 a. predetermined distance. 17 are screws for insertion through spaced holes 18 in the retainer for securing the latter to the door as shown.

The closing or active member 14 is a strip substantially triangular in cross-section, and has each of its three sides longitudinally grooved resulting in a structure having a neck portion 19 and two more hingeable portions 20 and 21, also a solid head 22 and a pair of ridged flanges 23 at the base edges of the strip. The altitude or height of the strip is such that when assembled, the head 22 of the strip will just clear the floor surface 11 to close the said gap between the bottom edge of the door and the floor sur- In. operation, the retainer 13 is positioned and loosely attached to the door, then the flexible strip 14 is slid within the retainer, the height of the ridged flanges 23 of the strip belng a little reater than the dimension of the retainer etween the web 15 and flanges 16 thereof to insure a snug fit within the embraces of the resilient flanges 16. The screws 17 are finally tightened with respect to holding the retainer and contained strip in rigid securement to the door. It is obvious that when the door is swung in either direction and the head 22 contacts a rug or the like, both the head and rug will yield to accommodate the passage of the strip 14, the three hingeable portions of the latter flexing, compressing and stretching in proportion to the stress each is under.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have' described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I- desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired, as fall within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is the following:

1. As an element of a weather strip, a strip of rubber substantially triangular in cross-section and provided with a solid head, said rubber strip being adapted to be attached to the bottom edge of a door and having each side thereof grooved longitudinally for flexing purposes.

2. As an element of a weather strip, a strip of flexible material having a grooved base and a solid head opposite the base and a neck intermediate the two, the neck being adapted to bend transversely of the strip,

3. A wea her strip adapted to be attached to the bottom edge'of a door and comprising a strip of channel plate having its flanges bent to be opposed to and spaced from the web of the plate, and a strip of rubber substantially triangular in cross-section and provided with a solid head, said rubber strip being adapted to be received within the channel plate, the flanges of which are adaptedto embrace the sides of the rubber strip adjacent to the base thereof, and the three sides of the rubber strip being grooved so that they will hinge or bend simultaneously in proportion to the stress exerted at such sides when the door to which said strips are attached is swung in either direction over a floor or the covering therefor and said head contacts therewith.

4. A weather strip for doors comprising a retainer attachable to the bottom edge of the door and a strip of flexible material adapted to be supported in the retainer, the latter consisting of a strip of sheet metal having its longitudinal edges bent over towards the center of the strip and in offset relation therewith forming thereby a channeled retainer, and the said flexible strip of material consisting of a body having longitudinal base flanges and a groove between said flanges, and a solid longitudinal head spaced from said flanges by a neck portion,

the body adapted to be slid within the retainer and the flanges of the latter adapted to grip the flanges of the body in holding relation, and the neck and the base of said body being adapted to hinge or bend simultaneously in proportion to the stress exerted on said neck and said base when the door to which said strips are attached is swung in either direction over a floor or the covering therefor and said head contacts therewith.

In testimony whereof I aflix my signature.

OTTO H. PETERSEN.
