1. Field
The present invention relates generally to fenestration structures. More specifically, embodiments of the present invention concern a door assembly with a door reinforcing brace that reinforces the door adjacent to door hardware.
2. Discussion of Prior Art
Conventional door assemblies and other fenestration products installed on a building or other enclosure can be exposed to damaging forces. With the application of an excessive force (such as an impact force applied to the door in a building ingress direction), the door and/or framework of the building can experience damage that permits unauthorized entry.
Various fenestration products have been designed to resist such forces and associated structural damage (including damage that permits unauthorized building entry). For instance, turning to
Another conventional door assembly with reinforcement structure is disclosed in U.S. Pat. No. 6,679,004. The disclosed door assembly includes a door mounted on a door jamb with a reinforced hinge. The hinge includes plates that each include a reinforcement projection. In yet another prior art door assembly, disclosed in U.S. Pat. No. 6,305,127, a door strike plate includes a flat body and a transverse projection. The strike plate is secured to a jamb with fasteners that extend through the flat body and the projection.
However, the prior art fenestration products have various deficiencies. For example, the U-shaped plate E has been found to conduct past any thermal barrier provided by the door assembly. The plate E can also interfere with smooth swinging operation of the door and is known to be unsightly. The reinforced hinge disclosed by the '004 patent has been found to be ineffective at resisting damage when excessive force is applied to the adjacent door. The strike plate of the '127 patent is deficient as part of a reinforced door assembly because the strike plate does not reinforce the door itself and restrict damage to the door.
The following brief summary is provided to indicate the nature of the subject matter disclosed herein. While certain aspects of the present invention are described below, the summary is not intended to limit the scope of the present invention.
Embodiments of the present invention provide a door assembly that does not suffer from the problems and limitations of the prior art fenestration products set forth above.
A first aspect of the present invention concerns a door assembly for presenting a closeable doorway opening between an interior and an exterior. The door assembly broadly includes a door and a door reinforcement brace. The door is operable to be swingably mounted for swinging movement into and out of a closed position in which the door is located generally within the doorway opening. The door presents opposite interior and exterior surfaces that face the interior and exterior, respectively, when the door is in the closed position. The door presents a perimetric edge surface that extends between the interior and exterior surfaces. The door reinforcement brace is attached to the door to overlie at least portions of the interior and edge surfaces to reinforce the door, with no part of the door reinforcement brace extending exteriorly beyond the exterior surface of the door.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Other aspects and advantages of the present invention will be apparent from the following detailed description of the embodiments and the accompanying drawing figures.
Preferred embodiments of the invention are described in detail below with reference to the attached drawing figures, wherein:
The drawing figures do not limit the present invention to the specific embodiments disclosed and described herein. The drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the preferred embodiment.

It will be appreciated that elements of the inventive door assembly 20, while preferably used to permit building ingress and egress by a person, can be installed for doors in various other applications. For instance, features of the door assembly 20 could be used to reinforce and secure the door of a cabinet or storage enclosure. The door assembly 20 preferably includes door jambs 28a,b, a door 30, hinges 32, a locking mechanism 34, hinge-side reinforcement braces 36, and a lock-side reinforcement brace 38.
The framework B includes conventional framed stud walls with a plurality of studs. The studs preferably include a pair of wall studs S1,S2 and a header (not shown) that cooperatively form the doorway opening 22. The wall studs S1,S2 each preferably comprise a wood two-by-four stud construction, although it is within the scope of the present invention where the wall studs S1,S2 are alternatively configured. For instance, the wall studs S1,S2 could be alternatively sized. Also, the wall studs S1,S2 could comprise formed metal studs.
Turning to
It is within the principles of the present invention where the door assembly 20 includes an alternative structure adjacent the door jambs 28a,b. For instance, the door assembly 20 could include one or two sidelight windows located adjacent to corresponding jambs 28a,b. Also, the door assembly 20 could include a transom window extending above the opening 22.
In the usual manner, the door 30 is operable to be swingably mounted for swinging movement into and out of a closed position (see
The perimetric edge surface 50 includes, in the usual manner, top and bottom edge sections (not shown). The perimetric edge surface further includes opposite upright edge sections 52a,b that extend between the top and bottom edge sections. Again, the upright edge sections 52a,b preferably extend from the interior door surface 46 to the exterior door surface 48. However, it is within the scope of the present invention where the upright edge sections 52a,b lie between but do not extend to the interior door surface 46 and/or the exterior door surface 48. The top and bottom edge sections and the upright edge section 52b are preferably flat and planar. The upright edge section 52a is also flat and planar except for mortise recesses, as will be discussed.
The door 30 preferably presents a door cavity 54 to receive the locking mechanism 34 (see
Turning to
The hinge plates 60,62 present a length dimension L1 that is sized to fit within the mortise recess 58. The hinge plate 62 is positioned within a corresponding mortise recess 58 and is secured to the door 30 with threaded fasteners 66 that extend through the holes 62b. The other hinge plate 60 is secured to the door jamb 28a with threaded fasteners (not shown) that extend through holes 60b. As will be discussed, the hinge-side reinforcement braces 36 are located between the corresponding hinge plate and the door.

The illustrated locking mechanism 34 is mounted in the door 30 so that the bolt 70 slides through the upright edge section 52a to engage the jamb 28b when the bolt is locked. Further, the bolt 70 is preferably positioned at a location spaced vertically between the top and bottom sections of the edge surface 50. However, the locking mechanism 34 could be alternatively vertically positioned along the upright edge section 52a. Furthermore, the door 30 and locking mechanism 34 could be configured so that the bolt opening 56 slides through another one of the edge sections to engage another jamb or the top cross beam or sill (or an alternative structure that cooperates with the bolt 70 to selectively lock the door 30).

The hinge-side reinforcement brace 36 preferably includes an interior brace section 78 and an edge brace section 80 (see
Preferably, the brace sections 78,80 are formed as part of a unitary plate structure and are joined along a bend 88 to form an L-shaped plate. The brace sections 78,80 are positioned to define an included angle Al that is about ninety degrees (90°) (see
While the brace sections 78,80 are preferably integrally formed with one another, it is within the scope of the present invention where the brace sections 78,80 are removably attached to one another along a connection. For instance, the brace sections 78,80 could have connector elements that cooperatively engage one another to interconnect the brace sections 78,80. Yet further, the hinge-side reinforcement brace 36 could have a connector that attaches to each of the brace sections 78,80 and thereby interconnects the brace sections 78,80.
When secured to the door 30, the edge brace section 80 preferably extends along and engages the upright edge section 52a (see
When the brace 36 is secured to the door 30, the space located exteriorly relative to the exterior surface 48 of the door 30 is preferably devoid of any part of the brace 36. That is, no part of the brace 36 extends exteriorly beyond the exterior surface 48 of the door 30. Preferably, the edge brace section 80 is spaced from the exterior door surface 48. However, the edge brace section 80 could extend up to the exterior door surface 48 from a location spaced interiorly of the exterior door surface 48.
While the brace 36 and hinge 32 are preferably positioned in engagement with the upright edge section 52a, it will be appreciated that the brace 36 could be installed along another section of the perimetric edge surface 50 (e.g., to provide door reinforcement adjacent the hinge). For instance, if the illustrated door were intended to be hinged along the top section of the edge surface 50, the brace 36 and hinge 32 would be correspondingly attached to the top section.
The hinge plate 62 and edge brace section 80 are secured to one another and to the door 30 by aligning the holes 62b of the hinge plate 62 with corresponding fastener openings 82 of the edge brace section 80. In this manner, threaded fasteners 66 can be inserted through holes 62b and openings 82 so that the fasteners 66 can be secured in the door 30. It is noted that the openings 82 are arranged in sets to accommodate hinges having different hole patterns.
The hinge plate 62 and the edge brace section 80 are preferably positioned within the corresponding mortise recess 58 and secured to the door 30 with fasteners 66. In the illustrated embodiment, the hinge plate 62 preferably overlies the edge brace section 80, with the edge brace section 80 positioned between the door 30 and the hinge plate 62. Thus, for each hinge 32 of the door assembly 20, a corresponding one of the braces 36 is secured between the hinge plate 62 and the door 30.
The edge brace section 80 presents a vertical length dimension L2 (see
While the illustrated edge brace section 80 is positioned within the recess 58, it is within the ambit of the present invention where the door 30 does not present the mortise recess 58, such that the edge brace section 80 projects outwardly beyond the edge surface 50 of the door 30. However, the mortise recess 58 could be sized so that the edge brace section 80 is only partly recessed relative to the edge surface 50.
Again, the hinge-side reinforcement brace 36 serves to restrict relative movement between the hinge plate 62 and the door 30 when an excessive interiorly directed force is applied to the door. For instance, if a force F is applied to the door (see
With the hinge-side reinforcement brace 36 installed, a region R1 of the door 30 is reinforced (see
Turning to
The lock-side reinforcement brace 38 preferably includes an interior brace section 90 and an edge brace section 92. The brace sections 90,92 each preferably have the form of a flat rectangular plate. Also, the brace sections 90,92 are each preferably made of metal, such as carbon steel or stainless steel, and preferably present a maximum thickness of about one-eighth of an inch (⅛″). However, it is within the ambit of the present invention where the brace sections 90,92 are alternatively shaped and/or include an alternative material. The edge brace section 92 preferably presents vertically spaced fastener openings 94. The interior brace section 90 preferably presents vertically spaced fastener openings 96. Preferably, the fastener openings 94 receive corresponding fasteners 98, and fastener openings 96 receive corresponding fasteners 100.
The edge brace section 92 also presents a bolt hole 102 that receives the bolt 70 when the brace 38 is secured to the door 30 (see
Preferably, the brace sections 90,92 are formed as part of a unitary plate structure and are joined along a bend 104 to form an L-shaped plate. The brace sections 90,92 are positioned to define an included angle A2 that is about ninety degrees (90°). Again, the principles of the present invention are applicable where the brace sections 90,92 are alternatively shaped and/or positioned relative to one another. For instance, the included angle A2 defined between the brace sections 90,92 could be greater than or less than ninety degrees (90°).
While the brace sections 90,92 are preferably integrally formed, it is within the scope of the present invention where the brace sections 90,92 are removably attached to one another along a connection. For instance, the brace sections 90,92 could have connector elements that cooperatively engage one another to interconnect the brace sections 90,92. Yet further, the hinge-side reinforcement brace 38 could have a connector that attaches to each of the brace sections 90,92 and thereby interconnects the brace sections 90,92.
When secured to the door 30, the edge brace section 92 preferably extends along and engages the upright edge section 52b. At the same time, the interior brace section 90 extends along and engages the interior surface 46. In the illustrated embodiment, the interior brace section 90 projects laterally inboard from the upright edge section 52b to define a projection dimension P, which is preferably about one inch (1″) or less (see
When the edge brace section 92 is secured to the door 30, the space located exteriorly relative to the exterior surface 48 of the door 30 is preferably devoid of any part of the brace 38. That is, no part of the brace 38 extends exteriorly beyond the exterior surface 48 of the door 30. Preferably, the edge brace section 92 is spaced from the exterior door surface 48. However, the edge brace section 92 could extend up to the exterior door surface 48 from a location spaced interiorly of the exterior door surface 48.
While the brace 38 is preferably positioned in engagement with the upright edge section 52b, it will be appreciated that the brace 38 could also be installed along another section of the perimetric edge surface 50 (e.g., to provide door reinforcement adjacent the locking mechanism 34). For instance, if the illustrated door were intended to be locked along the top section of the edge surface 50, the brace 38 would be correspondingly attached to the top section.
The edge brace section 92 is preferably secured to the door 30 with fasteners 98,100. The edge brace section 92 is mounted on the door 30 without being positioned within a mortised recess of the door 30. As a result, the edge brace section 92 projects outwardly from the edge surface 52 of the door 30. However, it is within the ambit of the present invention where the door 30 presents amortise recess that receives the edge brace section 92 such that the edge brace section 92 is partly recessed or fully recessed relative to the edge surface 52.
Again, the lock-side reinforcement brace 38 serves to restrict a region R2 of the door adjacent the bolt 70 (see
The illustrated lock-side reinforcement brace 38 is preferably used to reinforce the region R2 (see
The illustrated door assembly 20 preferably includes both types of braces 36,38 to reinforce the door 30. However, it will be appreciated that the door assembly 20 could employ only the hinge-side reinforcement braces 36 or only the lock-side reinforcement brace 38 without departing from the scope of the present invention.
In use, the brace 36 is secured to the door assembly 20 by locating the edge brace section 80 within the mortise recess 58 and in engagement with the upright edge section 52a while locating the interior brace section 78 in engagement with the interior surface 46. The hinge plate 62 and the edge brace section 80 are preferably secured to the door 30 with fasteners 66. The interior brace section 78 is secured to the door 30 with fasteners 86. The hinge plate 60 is secured to the jamb 28a with fasteners. For each hinge 32 of the door assembly 20, a corresponding one of the braces 36 is secured between the hinge plate 62 and the door 30.
The brace 38 is secured to the door assembly by locating the edge brace section 92 in engagement with the upright edge section 52b while locating the interior brace section 90 in engagement with the interior surface 46. The interior and edge brace sections 92 are secured to the door with corresponding fasteners 98,100. The brace 38 is positioned so that the bolt hole 102 receives the bolt 70 when the bolt 70 is locked.
