Application May 18, 1951 Serial No. 226,972

3 Claims.

The present invention relates to a magnetic Weatherstrip assembly for a threshold.

An object of the present invention is to provide a magnetic Weatherstrip assembly in which there is a fixed Weatherstrip element and a cooperating Weatherstrip element movably connected to the fixed element.

Another object of the present invention is to provide a magnetic Weatherstrip assembly wherein the movable Weatherstrip element is caused to be shifted into engagement with the door bottom under the magnetic influence of magnets installed. in the door bottom.

A further object of the present invention is to provide a magnetic Weatherstrip assembly which is simple in construction, inexpensive to manufacture and install, and highly efiective and efiicient in use.

Other and further objects of the present invention will become apparent from the following description taken in conjunction with the accompanying drawing, in which:

Figure l is a fragmentary perspective view showing a door in closed position over the wooden threshold with the magnetic Weatherstrip assembly of the present invention operatively connected to the door and threshold.

Figure'2 is a sectional view taken on the line 2-2 of Figure 1, the full lines indicating the position of the movable Weatherstrip element with the door in the closed position of Figure 1 and the dotted lines indicating the position of the such movable element when the door has been swung to open position and away from the threshold.

Figure 3 is an exploded perspective view showing a fragmentary bottom portion of the door and of the individual components comprising the Weatherstrip assembly of the present invention. Referring to the drawings, the numeral I0 designates an upstanding door which is movable into and out of position over'a wooden threshold As shown in Figure l, the door H] has been moved into its position over the threshold H, and to the door and threshold is operatively connected the magnetic Weatherstrip assembly of the present invention. For the accommodation of one of the components of the aforesaid assembly the bottom of the door I0, Figure 3,

has been cut away inwardly from its inner face |2 to a point short of its outer face I3. The cut away portion of the door bottom is provided with a plurality of spaced slots l4 extending inwardly from the door bottom, and in each slot is disposed a magnet It, the magnet being fixedly held in its respective slot by-means of an attaching plate I6 which bridgesthe bottom of the slot and is attached to the adjacent portion ofthe door bottom by means of screws passing through holes l8 provided in the plate 16'.

A strip. N3 of yieldable material, another component of the assembly of the present invention, extends across the entire-bottom of the cut out portion of the door and covers the attaching plateslfi. Specifically, the strip I9 is fabricated of rubber and has a binding strip 20 around each of its longitudinal edges. 1

The remaining components of the assembly of the present invention include a fixed weatherstrip. .element and a cooperating"Weatherstrip element movably connected to the fixed ele-'- ment. The fixed element is designatedby 'the numeral 2| and is termed a first Weatherstrip element, the element 2| being arranged longitudinally of the threshold I I and has one side-overlying and fixed to one side of the threshold. Specifically, the oneside of the element 2| is provided with an apron 22 which overlies and 'is fixed to the one side of the threshold by means ofscrews or the like 23; A first hook 24 extends along the other side of the element 2| and faces the fixed side or apron 22. of the elementZ The cooperating metal Weatherstrip element'is designated by thenumeral 25 and is termed'a second Weatherstrip element, the element 25 being arranged longitudinally of the threshold II inwardly of the first element 2| and is pivotally connected along one side to the other side of the first element 2| for vertical up and down movement. Specifically, a second hook 26 extends along one side of the second element 25 and faces the first hook 24, the second hook 26 interengaging with the first hook 24 and pivotally connecting the second element 25 along one side to the other side of the first element 2| for vertical up and down movement.

In operation, it will be apparent that as the door I6 is in its position over the threshold H, the free or other side of the metal Weatherstrip element 25 will be attracted by the magnets IE, to thereby cause vertical upward movement of the Weatherstrip element 25 into engagement with the strip l9 and form an effective sealing of the space intermediate the door bottom and the threshold. Upon movement of the door to its position away from the threshold II, the attraction of the magnets I9 is broken, resulting in vertical downward movement of the Weatherstrip element 25 to the position indicated in dotted lines in Figure 2 and consequent movement of the 3 free or other side of the Weatherstrip element 25 out of engagement with the strip l9.

What is claimed is:

1. The combination with a threshold and an upstanding door movable into and out of position over said threshold, the bottom of said door having a portion cut away inwardly from the inner face of the door to a point short of the outer face of the door, of a magnetic Weatherstrip assembly operatively connected to said threshold and door, said assembly comprising a first Weatherstrip element arranged longitudinally of said threshold and having one side overlying and fixed to one side of said threshold, a second metallic Weatherstrip element arranged longitudinally of said threshold inwardly of said firstelement and pivotally connected along one side to the other side of said first element for vertical upward and downward movement, a strip of yieldable material covering the cut away portion of the bottom of said door, and magnetic means in said door above said strip operable upon movement of said door into its position over said threshold to cause vertical upward movement'of said second Weatherstrip element into engagement with said strip.

2. The combination with a threshold and an upstanding door movable into and out of position over said threshold, the bottom of said door having a portion cut away inwardly from the inner face of the door to a point short of the outer face of the door, of a, magnetic weatherstrip assembly operatively connected to said threshold and door, said assembly comprising a first Weatherstrip element arranged longitudinally of said threshold and having one side over lying and fixed to one side of said threshold, a first hook extending along the other side of said first element and facing the fixed side of said element, a second metallic Weatherstrip element arranged longitudinally of said threshold inwardly of said first Weatherstrip element, a secyieldable material covering the cut away portion 4 of the bottom of said door, and magnetic means in said door above said strip operable upon movement of said door into its position over said threshold to cause vertical upward movement of said second Weatherstrip element into engagement with said strip.

3. The combination with a threshold and an upstanding door movable into and out of position over said threshold, the bottom of said door having a portion cut away inwardly from the inner face of the door to a point short of the other face of the door, said door having a plurality of spaced slots extending inwardly from the cut away portion of the bottom thereof, of a magnetic Weatherstrip assembly operatively connected to said threshold and door, said assembly comprising a first Weatherstrip element arranged longitudinally of said threshold and having one side overlying and fixed to one side of said threshold, a, first hook extending along the other side of said element and facing the fixed side of said first element, a second metallic Weatherstrip element arranged longitudinally of said threshold inwardly of said first Weatherstrip element, a second hook extending along one side of said second Weatherstrip element and facing said first hook, said second hook interengaging with said first hook and pivotally connecting said second Weatherstrip element along one side to the other side of said first Weatherstrip element for vertical upward and downward movement, a strip of yieldable material covering the cut away portion of the bottom' of said door, and magnets fixedly held in the slots in said'door and operable upon movement of said door into its position over said threshold to cause vertical upward movement of said second Weatherstrip element into engagement with said strip.
