Integral Interlocking Weather Stripping For Doors, Doorjambs And Thresholds

Abstract

An integral interlocking weather stripping for doors, doorjambs and thresholds is provided for an assembly which can be made and fitted at a factory and ready for complete installation within a building wall without need of later effecting weather stripping. There is no frictional engagement of the integral weather stripping flanges within the assemblage to cause wear or dislocation of the weather stripping. The weather stripping has outwardly projecting flanges of less thickness than the width of grooves in cooperating frame members which receive them. For weather stripping a threshold, a reversible extruded member with two weather-stripping flanges is mounted in a large groove at the bottom of the door to provide a further weather-stripping flange when one flange has become worn.

Description

This invention relates to interlocking doorjambs and thresholds to weatherstrip door openings.

It is an object of the present invention to provide door and doorjambs with built-in weather-stripping means and to eliminate the need for metal weather-stripping doors already installed in homes and buildings.

It is another object of the invention to provide built-in weather stripping for doors and doorjambs as well as the thresholds, that can sustain a considerable use of the door and which will not need considerable refurbishing to keep the doors and doorjambs adequately weather stripped.

It is a further object of the invention to provide a threshold air stripping device that is adjustable within the bottom groove of the door to arrange the same for different heights and to have interlocking engagement with a threshold ledge and which when worn can be removed from the slot and reversed to provide a weather-stripping run for interlocking engagement with the threshold ledge.

It is a further object of the invention to eliminate the need for the usual metal weather stripping of doors and thresholds wherein integral weather-stripping flanges are provided on the door edges, the same being integral with the door material itself extruded therewith, or integral or formed of the casing of a hollow door or door filled with wood pieces and wherein the receiving edge of the wall jamb is extruded integral molded shape that will receive the integral weather-stripping flanges of the door.

Other objects of the invention are to provide doors for weather stripping which are made with complete accuracy at the factory which eliminates the need for separate pieces to be tacked upon the door, wherein doors which are light in weight and screws are eliminated for the effecting of weather stripping, and wherein both the doors and the doorjambs bearing weather stripping can be delivered to the building site complete and accurately fitted with one another, the door hinged upon the doorjamb, completely weather stripped.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which

FIG. 1 is an elevational view of a door fitted into its jamb end containing the interlocked weather stripping and doorjamb constructed according to the present invention.

FIG. 2 is a transverse sectional view taken on line 2--2 of FIG. 1 of the door and doorjamb with the weather stripping provided integrally on side stiles and with the doorjambs formed of metal or wood to receive the integral flange of the door weather stripping.

FIG. 3 is a transverse sectional view of a hollow door having integral weather-stripping flanges and wood jamb members.

FIG. 4 is a transverse view of a similar hollow door as shown in FIG. 3 but with metal extruded doorjamb fashioned to receive the integral weather stripping of the door.

FIG. 5 is a vertical sectional view of a lower end of the door having a reversible weather stripping for engaging a ledge of a threshold and as viewed on line 5--5 of FIG. 1.

FIG. 6 is a transverse sectional view similar to FIG. 4 of a full hollow door formed of sheet or extruded metal in which the weather-stripping slots are provided thereon and wherein the doorjambs are provided with integral weather-stripping runs adapted to enter the door slots.

FIG. 7 is an enlarged view of a construction similar to the doorjamb of FIGS. 1 and 2, but wherein the door casing formed of sheet metal with the weather stripping formed of portions of the metal folded upon itself and wherein the doorjambs may be formed of wood and metal and of slots for receiving the door weather stripping.

Referring now particularly to FIGS. 1, 2 and 5, 10 generally represents a door formed of wood providing for the side edges with extruded metal stiles 11 and 12, that include outwardly projecting weather-stripping flanges 13 and 14 adapted to respectively enter side wood jamb pieces 16 and 17 formed of wood or extruded metal. The stiles can be made at a factory with the door and will include weather-stripping slots 18 and 19 for receiving respectively the weather-stripping flanges 13 and 14 of the stiles 11 and 12. The door 10 is connected by top and bottom hinges 21 and 22 the stile 11 of the door 10 and the doorjamb 16 so that the weather-stripping flange 13 is readily and easily accommodated by the jamb slot 18 of the side jamb 16. The doorjamb 17 is shaped differently since the weather-stripping flange 14 protrudes from the rear face of the door. The slot 19 that receives the weather-stripping flange 14 is such as to provide a doorstop against the inward movement of the door and the door to be held in the usual manner by a door lock 23.

At the bottom edge of the door 10 is an enlarged transversely extending slot 24 in which is provided in a tight fitting manner a hollow, rectangular, tabular weather-stripping member 25 having weather-stripping flanges 26 and 27 at its top and bottom sides, one extending in one direction and the other extending in the opposite direction. These weather-stripping flanges 26 and 27 are spaced to receive when the door is closed an integral outwardly extending weather-stripping flange 28 of a threshold 29.

It will be apparent that these weather-stripping members are not to be tacked upon the door but are integral formations that can be fitted and made a part of a full doorjamb and threshold assembly when delivered to the house or building where the assembly can be installed. Should there be excess wear upon the weather-stripping flange 26 at the lower edge of the member 25 so that it needs replacement, the member 25 will be removed from the slot 24 in the door, and reversed to have the weather-stripping flange 27 extended to receive the weather-stripping flange 28 of the threshold 29.

In FIG. 3 a molded or extruded door 30 is shown. This extruded door is made of metal and has at the hinge end an endwise projecting weather-stripping flange 31 that fits in a groove in a jamb 32 secured between frame members 32', 32". A hinge 33 is carried on this edge of the door and is connected to the doorjamb or frame 32. This jamb 32 and a jamb 34 at the opposite side of the door may be of wood or preferably extruded metal. The doorjamb 34 is provided with a stop ledge 35 and a groove 36 for receiving outwardly projecting flange 37 integrally formed with door 30 at its free end.

In FIG. 4 is shown a door 40 formed as a flat, rectangular, hollow metal casing. Flange 41 extends the full length of the door casing and projects outwardly of the lateral end of the door to which hinge 43 is secured in the same manner as flanges 13 and 31. The flange 41 is parallel to opposite sides of the door casing. Flange 42 at the free end of the door casing is integral therewith and extends the full length of the casing in the same manner as flanges 14 and 37. Flange 42 is also perpendicular to the side of the door facing frame member 46 which serves as a doorjamb. Member 46 has a groove 47 which receives flange 42. Frame member 44 has a groove 45 which receives flange 41. The flanges 41 and 42 like the flanges on doors 10 and 30 are thinner than widths of the grooves which receive them to prevent binding and sticking when the door is opened and closed. The frame members 44 and 46 may be hollow metal members made by extrusion in the same manner as door casing 40.

In FIG. 6 is shown a completely hollow door 50 formed of extruded metal and wherein the weather stripping receiving grooves 51 and 52 are provided on the lateral hinge end and side of the door instead of on the frame or jamb. The frame members 53 and 54 are extruded and are formed with weather-stripping flanges 55 and 56 respectively. Hinges 57 support the door 50 and the frame member 54 is provided with a ledge 58 to limit the inward swinging of the door. From this construction and with reference to the other constructions, it can be seen that the integral formations on the door and on the frame members can include either the weather-stripping flanges or the groove that receive the flanges. In all cases the complete assemblage of the door, door frame and threshold can be effected at the factory and made ready for easy assemblage at the place of installation of the same. The top and threshold pieces can be shaped and fitted at the factory and may be rigidly secured in the frame so that a complete unassembled door and doorjamb frame can be delivered to the place of installation. No separate weather stripping will need to be used.

FIG. 7 shows a metal door casing 60 filled with wood 61. The casing 62 is formed from metal sheet folded about the wood and having weather-stripping flanges 63, 64 at the hinge end and closing side of the door. The integral flanges are made by folding the sheet material upon itself to provide double thick sheet metal flanges. Side frame pieces 66 and 67 may be formed of wood, or extruded metal as in the form of the invention shown in FIG. 2 with grooves 68 and 69 for receiving the integral weather-stripping flanges 63 and 64. The door 60 is hung and attached to the frame piece 66 by hinges 71 and the frame member 66 is covered or held in place within the building by outer and inner cover plates 72 and 73. Outer and inner cover plates 74 and 75 are used to similarly to contain and mount the doorjamb 67 within the building wall.

It should now be apparent that in all of the forms of the invention now described that all of the weather stripping is an integral part of the doors and the jamb members.

It should also be apparent that this invention can well apply to the weather stripping of double doors where one of the doors remains fixed and provides for the jamb for the door that is opened. The integral weather stripping can be provided on the side edges of the doors where they join together and at the top and bottom as illustrated in connection with single doors.
