8 Claims. (Cl. 20-64) This invention relates to Weatherstripping constructions and more particularly to Weatherstripping adapted for use in insulating doors and other similar closure structures.

The primary object of this invention is to provide a Weatherstripping construction which will elfectively shield a house or other building from penetration by air currents, dust and the like, which will close any interstices between a door and the door frame and which will effectively provide a seal at the bottom of a door.

Still further objects of the invention reside in the provision of a Weatherstripping construction that is strong and durable, relatively easy to install by eliminating the necessity for doors of special construction or the necessity of having special tongues or grooves formed in the edges of the door, which is relatively inexpensive to manufacture and which is relatively easy to install by any home owner without requiring special instruction or training.

These, together with the various ancillary objects and features of the invention which will become apparent when the following description proceeds, are attained by this Weatherstrip construction, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 1 is a sectional detailed view illustrating the construction of the Weatherstripping as used at the bottom edge of a door;

Figure 2 is a sectional detail view similar to that of Figure l but showing the door in an opened position;

Figure 3 is a sectional detail view illustrating the construction of the vertical Weatherstripping members adapted to be secured to the door frame;

Figure 4 is a perspective view of the sheet having the resilient strip attached thereto which is adapted to be pivotally mounted below the bottom edge of a door; and

Figure 5 is a perspective view of Weatherstripping which is adapted to be secured to the door frame.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates a door to which the Weatherstripping comprising the present invention is adapted to be secured to insulate the building for which the door forms a closure from air currents, dust and the like. To the bottom of the door 10 there is secured a frame strip 12 which is held in position by means of screws 14 or other suitable fasteners. The frame strip 12 has a downwardly depending flange 16. Positioned against the frame strip 12 is an upper wedge 18 of resilient material such as rubber. Directly below the upper wedge 18 there is positioned a sheet 20 having an angularly downwardly extending portion 22 forming an actuating flange which terminates in a portion 24 extending substantially parallel to the main part of the sheet 20. Secured immediately below the sheet 20 is a lower wedge 26 of suitable resilient material which has its thickest portion thereof at a point remote from the actuating flange 22 and opposite from the position of the thicker portion of the wedge 18. Below the lower wedge 26 there is provided a plate 28. Screws 30 extend upwardly through the plate 28, the lower wedge 26, the sheet 20, the upper wedge 18, and the frame strip 12 to hold these elements in an assembled position. It is to be noted that the apertures 32 through the sheet 20 are of larger size than the shank of the fasteners 30 thus permitting pivoting movement of the sheet 20 relative to the door 10. The edge of the sheet 20 remote from the ice actuating flange 22 has bonded thereto a strip of resilient material 34 such as rubber or the like.

Extending across the opening for which the door 10 forms a closure is a door sill or threshold piece 36. By means of any suitable fasteners or the like a cam plate 38 having an angularly extending cam surface 40 is aflixed on the door sill 36. The cam plate 38 is adapted to be engaged by the actuating flange 22 when the door is being closed which will urge the sheet 20 to pivot. This will cause the thicker portions of the wedges 18 and 26 to become compressed as can be best seen in Figure 1. When the door becomes fully closed the portion 24 will rest on the top of the cam plate 36 and the resilient strip 34 will be held against the cam plate 40 forming a seal. Likewise, the sheet 20 will be held against the upper wedge 18 forming a seal therewith. This will prevent passage of any air currents, dust, and the like through the interstices that would normally exist between the door 10 and the door sill 36. When the door is opened the wedges 18 and 26 will be free to return to their normal shape thus urging the sheet 20 to return to its initial position. It is to be noted that the flange 16 will act as a guard for the sheet 20 preventing any foreign matter from accidentally forcing its way between the sheet 20 and the frame strip 12. v

Referring now to the Weatherstrip construction as is shown in Figures 3 and 5 it will be noted that the door frame 50 has aflixed thereto by means of screws 52 or other suitable fasteners one flange 54 of an angular Weatherstripping member the other flange 56 thereof extending at an acute angle relative to the flange 54. The

flange 56 is further bent as at 58 to form a portion substantially parallel with the flange 54. A resilient strip 60 is bonded to the inner surfaces of the flange 56 and the flange portion 58. When the door 10 is closed it will abut against the resilient strip 60. Since the flange portion 56 extends at an angle relative to the flange 54 and the frame 50 and since it is formed of a metallic material of resilient nature an effective seal will be formed between the resilient strip 60 and the door 10. The fasteners 52 extend through suitable apertures 62 in the flange 54, means being provided to countersink the heads of the screws or fasteners 52. The angle Weatherstripping as is illustrated in Figures 3 and 5 is used primarily along the vertical edges of the frame and at the top thereof for preventing passage of air currents between the door'10 and the frame 50. This structure is adapted to be used in conjunction with the Weatherstripping illustrated in Figures l, 2 and 4.

Since from the foregoing the construction and advantages of this Weatherstripping construction are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifications and equivalents may be resorted to, and obviously by reversing the position of mounting of the Weatherstripping seals can be provided for doors which open in opposite directions.
