Description
~ 32~333 INWARDLY S~INGING HINGED DOOR ASSEMBLY
Backqround of the Invention This invention relates generally to an inwardly swinging door and more specifically to an inwardly swinging door that is constructed using a multi-point lock, weatherstripping in one plane and a pressure equalization mem~er to provide for an improved weatherproof door.
Description of the Prior Art Most doors utilize a single point lock. When a single point lock is utilized, the door is cooperatively connected to the frame of the door only by means o~ the hinges and the single point lock. The hinges are typically multi-point and connect the door to the frame at the top, middle and bottom of the door. The multi-point connection helps in the preventing of bowing and hence leakage along the section that is open. However, because the swinging edge of the door is connected only by one point at the lock, bowing of the top and bottom of the door itself is more prevalent. Recently!
multi-point locks have been utilized for doors. However, these locks have most often been incorporated into doors for increased security. For example, U.S. Patent No. 4,548,342 discloses such a lock.
Still further, the prior art doors have been of a "sweep type" design. That is, the weatherstripping on the bottom of the door extended downward and generally came in contact with the threshold. Still further, no pressure equalization chambers were utilized to aid in the prevention of water seeping through the door. Such pressure equalization chambers are in existence for windows. However, the windows are generally outwardly swinging and also the designer of windows is not concerned with stepping up and over threshold as is the designer of doors.
The National Wood Window and Door Association is developing a standard for wood swinging patio doors. As part ~' f"~
` ``"` - 2 - ~32~3~3 of the standard with respect to air infiltration, the Association requires that the unit shall be tested for air leakage in accordance with the latest revision of ASTM E-283 "Standard test method for air leakage through exterior windows, curtain, walls and doors." Air infiltration shall not exceed 0.34 cubic feet per minute, per square foot overall area when tested at a uniEorm static air pressure difference of 1.56 pounds per square feet. The water penetration resistance in test standard is that the unit shall be tested for water penetration resistance in accordance with ASTM E-547 "Standard test method for penetration of exterior windows, curtain walls and doors by cyclic air pressure differential." The unit shall be tested under a static pressure difference of 2.86 PSF. A minimum of three cycles of no less than 5 minutes each shall be used during the test. At the conclusion of the test, no water shall have passed beyond the interior face of the door unit and overflowed into the room or flowed into the wall area.
The present invention is able to well surpass these standards and in fact air infiltration does not exceed 0.20 cubic feet per minute and the water penetration can be tested under a static air pressure difference of up to 6.24 PSF.
Further, with respect to structural claim testing, the present invention will take a 60 PSF positive/negative load using ASTM E-330 with no breakage or unit failure after loads are removed. Residual deflection is less than 0.4% of its span.
The present invention addresses the problems associated with prior art and provides for an improved door having increased air infiltration, water penetration and structural characteristics.
Summary of the Invention The present invention provides for an inwardly swinging door assembly for mountiny into a building frame. The door assembly includes a door member having a top edge surface, bottom edge surface and first and second side edge surfaces.
The assembly is provi~ed with means for hingedly mounting the - 3 ~ 93 door member to the frame. The mounting means is proximate one of the first and second sides. A multi-point lock is mounted proximate the other of the first and second sides, whereby the frame is engaged by the lock at more than one point. Single point weatherstrips are cooperatively connected to the top edge surface, bottom e~ge surface and first and second side edge surfaces. rrhe weatherstrips preferably have ~ngaging surfaces in one plane and comprise single strips of weatherstrip forming a continuous weatherstrip. A pressure equalization member is cooperatively connected to the frame for engaging the weatherstrip connected to the bottom eclge surface. Air infiltration of the door assembly, as measured by ASTM E-283, does not exceed 0.34 ft3/min/ft2 of the door assembly, and the door assembly will not allow water penetration, as measured by ASTM E-547, at 2.86 lbs/ft2.
In a preferred embodiment, the weatherstrips are all in a single plane and the weatherstrip is cooperatively connected at intersections of the surfaces, whereby a continuous weatherstrip is formed around the door member.

Datailed Description of the Invention Referring to the ~igures, wherein like numerals represent like parts throughout the several views, there is generally illustraked at 10 an inwar~ly swinginy door assembly.
The door assembly 10 is mounted in a frame 11. As shown B
~ _ 4 _ ~3~ 3 in Fig. 1, the frame 11 is sized to receive not only the inwardly swinging door assembly 10 but also a stationary panel member, generally designated as 12. However, it is understood that the door assembly 10 may be mounted alone in a smaller frame or alternately, the frame may be larger to accommodate a plurality of stationary panel members 12.
Still further, the position of the door assembly 10 may be varied within the frame 11. For example, where the frame 11 is sized sufficiently to accommodate two stationary panels and a door assembly 10, the door assembly 10 may be on either ends or in the center.
The stationary panel member 12, which is optional to the present invention, may be of any suitable type well known in the industry. The panel member 12 includes a double pane window assembly 12a which consists of an inner glass panel and an outer glass panel cooperatively connected together and mounted to a first side rail 12b, second side rail 12c, top rail 12d and bottom rail 12e. Moldings 13 are cooperatively connected and in turn fastened into the side rails 12b-e by means of nails 14. The molding cooperatively connected to the first side rail 12b is fastened to the portion of the frame 11, as shown in Fig. 2b. Similarly, the molding 13 cooperatively connected to the second side rail 12c is fastened by means of the nail 14 into the center support member 15. Similarly, molding adjacent the top and bottom rails 12d and 12e are fastened into the frame 11 by means of nails. The sill member 16, who cross section is best seen in Fig~ 3c, extends between the two generally vertical members of the frame 11. The sill member 16 comprises a wooden portion 16a cooperatively connected to a metal portion 16b to form the sill 16. A threshold 16c is cooperatively connected to the top of the sill 16. The center support member 15 extends between the sill member 16 and the top horizontal member of the frame 11.
A first side jamb assembl~ 17 is cooperatively connected adjacent the first side rail 12b and extends between the frame 11 and 5ill 16. The first side jamb assembly 17 `" - 5 ~ 3 9 3 includes a first member 17a cooperatively connected to a second member 17b which forms -the outer surface of the door opening. The second member 17b has a C-shaped section 17c which is adapted to receive an optional sliding screen door.
Suitable weather stripping 18 is utilized between the first siderail 12b and the second member 17b of the first jamb assembly 17.
A first astragal assembly 19 is cooperatively connected - to the center support member 15 and extends between the horizontal upper member of the frame 11 and the sill 16. The astragal assembly 19 includes a first member l9a which is cooperatively connected to the center support member 15 and has a generally planar bottom member which extends beyond the edges of the center support member 15. The ends of the planar bottom l9b are angled slightly upward. The first member also has two upwardly extending members l9c which have a top portion which extends generally outward. The second member l9d of the astragal assembly 19 has a configuration, shown in cross section in Fig. 2a, which is symmetrical on both sides of the center support member 15. The second member l9d engages the outwardly extending portion of the upwardly extending member l9c and also the stationary panel 12. Suitable weatherstripping 20 may be utilized to weatherproof the stationary panel 12. While the above-described construction of the stationary panel 12 ispreferred, it is understood that any suitably constructed stationary panel 12 may be utilized.
The inwardly swinging door assembly 10 includes a door member lOa comprising a double pane assembly 21 mounted in a door panel 22. The door panel 22 has a first side rail 22a, second side rail 22b, top rail 22c, and bottom rail 22d, all cooperatively connected by means well known in the art to form the door panel. Suitable molding strips 23 may be utilized, where appropriate, around the double pane assembly 21. The construction of a door member 20, as described so far, is well known in the art.
The first side rail 22a has an edge surface 24. The ~ 6 - ~32~93 second rail 22b has an edge surface 25. The top rail 22c has a top edge surface 26 and the bottom rail 22d has a bottom edge surface 27. As can be seen from the drawings, none of the edge surfaces 29 through 27 are planar. However, the desiynations for the edge sur~aces generally designate the edges of the door member 20. However, as will be d;scussed more fully hereafter, the edge surEaces have cutouts to accommodate weatherstripping.
Three hinges 28 are cooperatively connected to the center support member 15 and the door member 20, proximate the edge surface 24 by means well known in the art. The door assembly 10 is hingedly mounted for swinging inward into a building. The door assembly 10 also includes a ~ulti-point closing and locking latch assembly generally designated as 29. The locking assembly 29, as shown, includes three separate locking sub assemblies 30, 31 and 32. The locking sub assemblies are interconnected by means of an espagnolette bar 33. Rotation of the handle 34 will cause the locking assembly 29 to move between a latched and unlatched position.
Rotation of the hand~e 34 causes all three sub assemblies to move between the latched and unlatched position. Further, by inserting a key and rotating the key into a lock 35, the locking assembly 29 may be locked by moving the bolt 29a into a strike plate 49. Locking assemblies 29 are well-known in the art, but to date have essentially been used for improved security. The multi-point locking assembly 29, with the three locking sub assemblies 30 through 32 provide for increased protection against a forced entry. However, such a locking assembly 29 also has significant advantages with respect to the weather integrity of the door. By latching the door at 30 and 32 as well as at 31, the door is secured along three points. This will prevent bowing of the door at the top and bottom as well as maintain the integrity of the weatherseal proximate the locking sub assemblies 30 through 32. Such a latch assembly is described in U.S. Patent No.
. ... . . .
4,548,432. ~ther, such a locking asse~bly 29 is available for purchase from , j ~
- 7 - 1320~93 Fixfabriken in Gotenberg, Sweden. The oval lines shown in phantom 60, 61 and 62 in Figs. 3a, 3b and 3c, respectively, show the locations of where the locking sub assemblies 30, 31 and 32 are positioned.
The weatherstripping, generally designated as 36, as will be described more fully hereafter, is cooperatively connected to the edge surfaces 24 through 27 on the door member 20. The weatherstripping 36 comprises four sections 36a through d and are carried entirely by the door member 20 and further are in one plane. Still further, the sections are cooperatively connected at the intersections to form one continuous weatherstrip around the door. The weatherstripping 36 can be seen in detail in Figs. 2a, 2c, 3a and 3c. As seen in Fig. 2a, the first edge surface 24 has a notched area in which the weatherstrip 36a is fastened.
Weatherstrip section 36a, as with the other sections, is a bulb type weatherstrip and has a first end 36e secured in a cavity 37 in door panel 22a. The section 36a has a protruding bulb section 36f, which is shown in a compressed configuration in Fig. 2a. The bulb section then continues and is again cooperatively connected into the cavity 37. The astragal assembly l9 has a weatherstrip engaging surface l9e that comes in contact with the bulb portion 36f of the section 36a.
As seen in Fig. 2c, the second edge surface 25 has a notched area in which the weatherstrip 36b is fastened.
Weatherstrip section 36b is a bulb-type weatherstrip and has a first end 36g secured in a cavity 38 in door panel 22b.
The section 36b has a protruding bulb section 36h, which is shown in a compressed configuration in Fig. 2c. The bulb section then continues and is again cooperatively connected into the cavity 38. A second side jamb assembly 48 is similar to the first side jamb assembly 17. The second side jamb assembly 48 is cooperatively connected to the frame ll and is proximate the side rail 22b and extends between the frame 11 and sill 16. The second side jamb assembly 48 includes a first member 48a cooperatively connected to a - 8 - 1~20393 second member 48b which forms the outer surface of the door opening. The second member 48b has a C-shaped section 48c which is adapted to receive an optional. sliding screen door.
The second side jamb assembly 48 also includes a flange 48d S which in turn has a generally perpendicular cross section piece 48e. The cross section piece 48e forms a weatherstrip engaging surface which contacts the bulb portion 36h of the weatherstrip section 36b.
As seen in Fig. 3a, the edge surface 26 has a notched area in which the weatherstrip 36c is fastened. Weatherstrip section 36c is a bulb-type weatherstrip and has a first end 36i secured in a cavity 39 in the door panel 22c. The section 36c has a protruding bulb section 36j, which is shown in a compressed configuration in Fig. 3a. The bulb section then continues and is again cooperatively connected into the cavity 39. A top jamb assembly 50 as shown is Fig. 3a is cooperatively connected to the frame 11 and is proximate the top rail 22c and extends between the generally vertical upright members of the frame 11. The top jamb assembly 50 includes a first member 51 cooperatively connected to a second member 52. The second member 52 is adjacent and cooperatively connected to the frame 11, as previously discussed. The second member 52 includes a downwardly depending member 52a which forms a weatherstrip engaging surface which contacts the bulb portion 36j of weatherstrip section 36i. An optional assembly 53 may be attached to the top jamb assembly 50 when an optional screen is utilized.
As seen in Fig. 3c, the edge surface 27 has a notched area in which the weatherstrip 36d is fastened. Weatherstrip section 36d is a bulb-type weatherstrip and has a first end 36k secured in a cavity 40 in the door panel 22d. The section 36d has a protruding bulb section 361, which is shown in a compressed configuration in Fig. 3c. The bulb section then continues and is again cooperatively connected into the cavity 40.
The metal sill portion 16b has a downwardly sloping top surface 16d and two generally upright support members 16e and ;~ 9 ~.32~93 16f. Further, the sill portion 16b extends past the support member 16e and has a further top surface 16g on which a guide 41 for a screen door may optionally be secured. At one end of the top surface 16d, an upwardly extending mounting member 16h is formed. A pressure equalization member, generally designated as 42, is cooperatively connected to the mounting member 16h of the middle sill 16b. The pressure equalization chamber extends the entire width between the frame 11 and the center support member 15. The pressure equalization member 42 has a first vertical member 43. The bottom end of the first vertical member 43 rests on the sill 16b. The height of the member 43 is greater than the pressure head that has to be withstood, approximately 1-1/2 inches. A second generally vertical member 44 has a bottom portion which engages the mounting member 16h. A horizontal section 45 is cooperatively connected between the first and second vertical sections 43 and 44. The second vertical member 44 has a weatherstrip engaging surface 44a that comes in contact with the weatherstrip 36d and forms the weatherseal. The top portion of the pressure equalization member 42 forms a generally U-shaped trough. This ~-shaped trough has a plurality of drain holes 46 spaced along its length. The pressure equalization member 42 also an inverted U-shaped area which has a plurality of drain holes 47 spaced along its length. A water shed member 55 has a first member 55a which extends across the width of the door member lOa and is cooperatively connected to the bottom rail 22d and an outwardly and downwardly extending section 55b which acts as a water shed for any water which cascades down the outer surface of the door lOa, to prevent access of the cascading water into the pressure equalization member 42.
All four of the weatherstrip engaging surfaces l9e, 44a, 52a and 48e oE the door assembly 10 are in the same plane.
Fig. 4 is a front plan view of one corner section of the door lOa. The four weatherstrip segments are cooperatively connected at the intersections to form a continuous weatherstrip around the door member. Qnly one corner of the - lO 13203~3 door 10a is shown in detail, but the other four sections are similarly constructed. Fig. 4 shows that the bulb sections 36j and 3~h are cooperatively connected al.ong a seam 70 to form one continuous weatherstrip.
~pplicants have found that by utilizing the multi point lock ~n connection with weatherstripping cooperatively connected on all four sides to the door and a pressure equalization chamber that the door assembly is able to meet the qualifications as set forth in the description of the prior art in this application. The weatherstrip of the present invention is kept up off the ground and accordingly stays dryer than the weatherstrip of the prior art. The prior art often puts weatherstrip on the outside and the weatherstrip then becomes wet and air infiltration and water are then more easily able to pass through the weatherstrip barrier.
Other modifications of the invention will be apparent to those skilled in the art in light of the foregoing description. This description is intended to provide specific examples of individual embodiments or the use of elements having spe~ific configurations and shapes as presented herein. All alternative modifications and variations of the present invention which follow in the spirit and broad scope of the appended claims are included.
Backqround of the Invention This invention relates generally to an inwardly swinging door and more specifically to an inwardly swinging door that is constructed using a multi-point lock, weatherstripping in one plane and a pressure equalization mem~er to provide for an improved weatherproof door.
Description of the Prior Art Most doors utilize a single point lock. When a single point lock is utilized, the door is cooperatively connected to the frame of the door only by means o~ the hinges and the single point lock. The hinges are typically multi-point and connect the door to the frame at the top, middle and bottom of the door. The multi-point connection helps in the preventing of bowing and hence leakage along the section that is open. However, because the swinging edge of the door is connected only by one point at the lock, bowing of the top and bottom of the door itself is more prevalent. Recently!
multi-point locks have been utilized for doors. However, these locks have most often been incorporated into doors for increased security. For example, U.S. Patent No. 4,548,342 discloses such a lock.
Still further, the prior art doors have been of a "sweep type" design. That is, the weatherstripping on the bottom of the door extended downward and generally came in contact with the threshold. Still further, no pressure equalization chambers were utilized to aid in the prevention of water seeping through the door. Such pressure equalization chambers are in existence for windows. However, the windows are generally outwardly swinging and also the designer of windows is not concerned with stepping up and over threshold as is the designer of doors.
The National Wood Window and Door Association is developing a standard for wood swinging patio doors. As part ~' f"~
` ``"` - 2 - ~32~3~3 of the standard with respect to air infiltration, the Association requires that the unit shall be tested for air leakage in accordance with the latest revision of ASTM E-283 "Standard test method for air leakage through exterior windows, curtain, walls and doors." Air infiltration shall not exceed 0.34 cubic feet per minute, per square foot overall area when tested at a uniEorm static air pressure difference of 1.56 pounds per square feet. The water penetration resistance in test standard is that the unit shall be tested for water penetration resistance in accordance with ASTM E-547 "Standard test method for penetration of exterior windows, curtain walls and doors by cyclic air pressure differential." The unit shall be tested under a static pressure difference of 2.86 PSF. A minimum of three cycles of no less than 5 minutes each shall be used during the test. At the conclusion of the test, no water shall have passed beyond the interior face of the door unit and overflowed into the room or flowed into the wall area.
The present invention is able to well surpass these standards and in fact air infiltration does not exceed 0.20 cubic feet per minute and the water penetration can be tested under a static air pressure difference of up to 6.24 PSF.
Further, with respect to structural claim testing, the present invention will take a 60 PSF positive/negative load using ASTM E-330 with no breakage or unit failure after loads are removed. Residual deflection is less than 0.4% of its span.
The present invention addresses the problems associated with prior art and provides for an improved door having increased air infiltration, water penetration and structural characteristics.
Summary of the Invention The present invention provides for an inwardly swinging door assembly for mountiny into a building frame. The door assembly includes a door member having a top edge surface, bottom edge surface and first and second side edge surfaces.
The assembly is provi~ed with means for hingedly mounting the - 3 ~ 93 door member to the frame. The mounting means is proximate one of the first and second sides. A multi-point lock is mounted proximate the other of the first and second sides, whereby the frame is engaged by the lock at more than one point. Single point weatherstrips are cooperatively connected to the top edge surface, bottom e~ge surface and first and second side edge surfaces. rrhe weatherstrips preferably have ~ngaging surfaces in one plane and comprise single strips of weatherstrip forming a continuous weatherstrip. A pressure equalization member is cooperatively connected to the frame for engaging the weatherstrip connected to the bottom eclge surface. Air infiltration of the door assembly, as measured by ASTM E-283, does not exceed 0.34 ft3/min/ft2 of the door assembly, and the door assembly will not allow water penetration, as measured by ASTM E-547, at 2.86 lbs/ft2.
In a preferred embodiment, the weatherstrips are all in a single plane and the weatherstrip is cooperatively connected at intersections of the surfaces, whereby a continuous weatherstrip is formed around the door member.

Datailed Description of the Invention Referring to the ~igures, wherein like numerals represent like parts throughout the several views, there is generally illustraked at 10 an inwar~ly swinginy door assembly.
The door assembly 10 is mounted in a frame 11. As shown B
~ _ 4 _ ~3~ 3 in Fig. 1, the frame 11 is sized to receive not only the inwardly swinging door assembly 10 but also a stationary panel member, generally designated as 12. However, it is understood that the door assembly 10 may be mounted alone in a smaller frame or alternately, the frame may be larger to accommodate a plurality of stationary panel members 12.
Still further, the position of the door assembly 10 may be varied within the frame 11. For example, where the frame 11 is sized sufficiently to accommodate two stationary panels and a door assembly 10, the door assembly 10 may be on either ends or in the center.
The stationary panel member 12, which is optional to the present invention, may be of any suitable type well known in the industry.
