Specifically, the invention relates to a door assembly with multi-piece stiles composed of different materials and secured together with dovetail joints.
BACKGROUND OF THE INVENTION
1. TECHNICAL FIELD
The invention relates generally to hinged door assemblies which are mounted in an entry way. More particularly, the invention relates to a door assembly having skins secured to a frame. Specifically, the invention relates to a door assembly with multi-piece stiles composed of different materials and secured together with dovetail joints.
2. BACKGROUND INFORMATION
Doors are movable barriers used to cover an opening. A traditional household door can come in a variety of shapes and sizes depending on the desired look.
However, the inner and outer skins of a door share the same profile, meaning that the design on the outside is the same as the design on the inside.
A traditional hinged door is secured on one side to a door frame opening with hinges and secured to the other side with a locking mechanism. The frame may be comprised of four pieces, including a top and bottom rail secured between a hinge stile and a lock stile. The connection points of the frame may have dovetail joints machined in them so that the frame is a sturdy assembly. Skins are then secured to each face of the door frame assembly with an internal core separating these skins.
The skins may be composed of fiberglass, wood, or any other suitable material, while the core may also be solid wood or a spray foam composite material.
Traditionally, the back side of each skin is flush and adapted to receive an adhesive to secure the skin to the frame assembly. In order to assemble the door, the frame is assembled and one of the skins is secured to one side of the frame. Next, a foam core is inserted between the frame assembly and against the installed skin. Finally, the opposing skin is then glued to the open side of the door frame.

DETAILED DESCRIPTION OF THE INVENTION
At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements of the invention. While the present invention is described with respect to what is presently considered to be the preferred embodiments, it is to be understood that the invention as claimed is not limited to the disclosed aspects.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of the ordinary skill in the art to which this invention belongs. Although any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods, devices, and materials are now described.
The door assembly of the present invention is indicated generally at 20, and is particularly shown in Figs. 1-19. As specifically seen in Fig. 1, a preferred embodiment door assembly 20 includes a first skin 22 with a variety of panels 24. As seen in Fig. 2, door assembly 20 also includes a second skin 26 which is secured to the door frame 28 opposite first skin 22 and will be described in further detail below.
Door frame 28 includes four components in a preferred embodiment. A lock stile 30 is parallel and spaced apart from a hinge stile 32. The hinge and lock stiles define the vertical perimeter of the door and are preferably spaced apart approximately the same distance as the length of a top rail 34 and a bottom rail 36.
Lock stile 30 includes dovetail joints 38 extending from a top end 39 and a bottom end 41 to ensure a secure engagement with the top and bottom rails. Hinge stile 32 also includes dovetail joints 38 extending from a top end 45 and a bottom end 47.
In accordance with one of the main features of the present invention, a plurality of slots 40 is formed in both a front side 42 and a back side 44 of lock stile body 46. In a preferred embodiment, slots 40 are formed in body 46 and extend vertically the full length of body 46, however, it is within the spirit in the scope of the present invention as claimed that the slots extend for merely 25% of the height of the frame, 50% of the height of the frame, or any other suitable length. As seen in Figs. 3 and 4, slots 40 include sidewalls 48 and a bottom wall 50 which define a generally rectangular opening. While the protrusion is preferably defined with a rectangular cross-section, any suitable cross-section may be incorporated, including semi-circular, square or any other shape.
Moving on to Figs. 5 and 6 and in accordance with yet another main feature of the present invention, hinge stile 32 is arranged similar to lock stile 30.
Hinge stile 32 includes a plurality of slots 40 arranged vertically throughout the length of body 52 of hinge stile 32.
Fig. 7 is a bottom view of bottom rail 36. Bottom rail 36 includes a pair of bottom slots 54 extending along the length of bottom rail 36. Bottom slots 54 are preferably arranged to receive a door sill seal. Further, bottom rail 36 includes receiving portions 56 which are complimentary shaped to and arranged to contact the dovetail joint of the hinge and lock stiles.
Referring to Figs. 2 through 6, lock stile body 46 includes an inner wall 43 and hinge stile body 52 includes an inner wall 49. Further, top rail 34 and bottom rail 36 each include inner walls 35 and 37 respectively. Advantageously, inner walls 35, 37, 43 and 49 define an internal cavity 75.
In accordance with yet another main feature of the present invention, Fig. 8 illustrates first skin 22 with a back side 58 having a plurality of protrusions 60 extending therefrom. In a preferred embodiment, protrusions 60 are spaced a distance A from a top edge 62 of skin 22. Further, a similar distance is incorporated for the bottom end of the skin (not shown). Advantageously, this arrangement allows the second skin back side 58 to be flush against top rail 34 and bottom rail 36 while allowing protrusion 60 to engage slots 40. While a preferred embodiment second skin includes five protrusions, any number or arrangement of protrusions may be incorporated without departing from the spirit and scope of the present invention as claimed. Further, protrusions 60 are illustrated with generally square walls extending from the back side of the skin and a rounded top end. Protrusion 60 may have a varying width as well as any suitable shape so long as they mate with slots 40. Finally, protrusions 60 are also spaced apart a distance B which can also be varied so long as the requirements above are satisfied.
Fig. 9 illustrates top rail 34 being inserted in the direction of arrow 64 to install the top rail on frame 28 along top end 39. An adhesive 66 is placed on inner wall 35 and receiving portion 56 to secure the top rail to lock stile 30. A similar process is completed with respect to hinge stile 32 to secure the other side of top rails 34 to the hinge stile. While the adhesive is described as being placed on inner wall 35, the adhesive may also be placed directly on the hinge and lock stiles.
Fig. 10 is a top view of top rail 34 installed on dovetail joint 38 of lock stile 30.
In particular, dovetail joint 38 is slidingly engaged with receiving portion 56 of top rail 34. Advantageously, this arrangement allows top rail 34 to be secured on lock stile 30 and permit movement only in an upward direction.
Figs. 11-13 illustrate the attachment of first skin 22 and second skin 26 to lock stile 30 as well as locating a foam core 68 between the skins in cavity 75.
Fig. 11 illustrates skins 22 and 26 prepared for installation on lock stile 30, while a similar arrangement is found at hinge stile 32, but not shown. As discussed above, skin 22 includes a back side 58 with protrusions 60 extending away from the skin. The first skin 22 also has a front side 70 which includes a variety of panels as discussed above.
Second skin 26 includes a back side 72 having a plurality of protrusions 60 extending therefrom and a front side 74 opposite back side 72 and also including a plurality of panels.
Fig. 12 illustrates first skin 22 and second skin 26 in the installed position after forcing protrusions 60 within slots 40. Specifically, skin 22 is forced in the direction associated with arrow 76 while skin 26 is forced in the direction associated with arrow 78. In a preferred embodiment and seen in Figs. 12 and 13, adhesive is located along the back side 58 of skin 22 and back side 72 of skin 26 such that adhesive bonds between the back sides 58, 72 and lock stile 30 and a top rail outer surfaces 29A and 29B. Further adhesive is also located within slots 40 and on protrusions 60 such that there is an increased adhesive area at the protrusions. During the installation, skins 22 and 26 are forced in their respective directions until protrusions 60 are fully seated within slots 40. Protrusions 60 and slots 40 may also be arranged such that there is a slight interference fit to ensure that the skins do not become separated from the frame while the adhesive is curing.
Fig. 14 illustrates the top corner of a preferred embodiment door assembly 20.
Top rail 34 is adhesively secured to lock stile 30, while skins 22 and 26 are each adhesively secured to top rail 34 and lock stile 30. Accordingly, the present invention creates a sounder and more secure bound between door skins 22 and 26 and lock stile 30 and hinge stile 32 (not shown) while retaining the traditional look of a standard door.
Having described the structure of the first embodiment, only those portions of the second embodiment which are different than the first embodiment are described in detail. Likewise, similar numerals refer to similar parts throughout the various embodiments.
Fig. 15 and 16 illustrate a second preferred embodiment, with a first skin 80 and a second skin 82. In accordance with yet another main feature of the present invention, skins 80 and 82 have distinct and different outer surfaces 84 and respectively. Further, inner surfaces 85 and 87 of skins 80 and 82 are also distinct from each other. While the second preferred embodiment is shown with six panels 24 on the first skin and two panels 83 on the second skin, any arrangement of first and second skins that have a distinct outer appearance may be utilized.
Advantageously, this allows the purchaser to have a first skin which matches the exterior of the dwelling, while having a second skin facing the interior of the dwelling that again matches a completely different environment than the outside.
Another advantage of the preferred embodiments is the ability to selectively size the door using protrusions 60 and slots 40. Specifically, protrusions 60 may align with only a portion of slots 40, thereby having a portion of the skins hang over the frame. The skin can then be trimmed to reduce the side of the door. The hinge and lock stiles may then include an additional member bolted thereon to ensure a proper door size.
In a second preferred embodiment, frame 88 is composed of six pieces, top rail 34 and bottom rail 36 remaining the same as the previous embodiment. However, lock stile 90 includes a high quality outer piece 92 and a low quality interior piece 94.
Hinge stile 96 also includes a high quality outer piece 98 and a low quality inner piece 100. High quality pieces 92 and 98 both include dovetail joints at the top and bottom portions and define the outer most edges of the frame. High quality pieces 92 and 98 are also thin and incorporated at the ends to provide the appearance of a hard wood or high quality door throughout the frame construction, while reducing costs by incorporating low quality pieces 94 and 100. Further, low quality pieces 94 and 100 include protrusions 40 similar to the first embodiment throughout their length.
Advantageously, incorporating low quality pieces 94 and 100 for the entire length of the slots ensures that machining of the slots is more readily accomplished without a waste of material.
Finally, high quality piece 92 is preferably adhesive secured to low quality piece 94, while high quality piece 98 is also adhesively secured to low quality piece 100.
Accordingly, when the high quality and low quality pieces are attached, they form the lock stile and hinge stile described in the first preferred embodiment in a more cost effective manner.
Having described the structure of the first two embodiments, only those portions of the third embodiment, which are different than the first two embodiments, are described in detail. Likewise, similar numerals refer to similar parts throughout the various embodiments.
Figs. 17-19 illustrate a third preferred embodiment with a first skin 102, a second skin 104, and a frame 106. Frame 106 is generally shaped identical to the first preferred embodiment frame, however the incorporation of the second preferred embodiment frame with high quality and low quality pieces is within the spirit and the scope of present invention as claimed. Further, first skin 102 is arranged similar to first skin 22 in that there are six panels 24. Second skin 104 has three panels 108 in the third preferred embodiment to provide a distinct and different appearance than the first skin. Frame 106 includes a lock stile 110 and a hinge stile 112.
In accordance with one of the main features of the present invention, lock stile 110 and hinge stile 112 (not shown) include a plurality of protrusions 114 extending from both sides of each stile. Further, skins 102 and 104 each include a back side 116 and 118 respectively. A plurality of slots 120 are formed within back sides 116 and 118 so that slots 120 are arranged to receive protrusions 112 of lock stile 110 and hinge stile 112.
As discussed in the first preferred embodiment, installation of the third preferred embodiment skins is similar in that first skin 104 is forced in the direction associated with arrow 122 until protrusions 114 are inserted within slots 120, while the second skin is forced in the direction associated with arrow 124 until protrusions 114 are inserted within slots 120. Once again, this arrangement provides for an increased adhesion contact area as well as an interference fit between the skins and the stiles.
Having described the structure of the preferred embodiments, a preferred method of manufacturing will be described in detail and should be read in light of Figs.
1-19.
Initially, plurality of slots 40 are formed in frame 28, and preferably in lock stile 30 and hinge stile 32. Next, a plurality of protrusions 40 are formed on back side 58 and 72 of the skins. The slots may be formed by machining or any other suitable removable technique. Similarly, protrusions 60 may be formed by removing material with a machining apparatus or by adhesively securing preformed protrusions on the back side of each skin. Alternatively, slots 40 may be formed in the skins, while protrusions 60 may be formed on frame 28 without departing from the spirit of the invention.
Next, adhesive is located on either frame 28 or back side 58 and 72 of skins and 26. The skins are then directed towards the frame such that the protrusions 60 are inserted within the respective slots 40 of the frame. After one side has been inserted, foam core 68 is disposed within the frame or may be placed by blowing foam insulation within the frame.
Frame assembly 28 is formed by machining top rail 34 with receiving portions 56 on each end and bottom rail 36 with the same receiving portions 56. Lock stile 30 and hinge stile 32 each include dovetail joints 38 on each end. The dovetail joints and receiving protrusions are complimentary shaped to ensure a tight and secure fit as well as provide increased contact surface for the adhesive to cure. Frame 28 is finally formed by securing the dovetail joints and receiving portions of the lock stile, hinge stile, top rail and bottom rail with adhesive.
Moving on to Figs. 5 and 6 and in accordance with yet another main feature of the present invention, hinge stile 32 is arranged similar to lock stile 30.
Hinge stile 32 includes a plurality of slots 40 arranged vertically throughout the length of body 52 of hinge stile 32.
Fig. 7 is a bottom view of bottom rail 36. Bottom rail 36 includes a pair of bottom slots 54 extending along the length of bottom rail 36. Bottom slots 54 are preferably arranged to receive a door sill seal. Further, bottom rail 36 includes receiving portions 56 which are complimentary shaped to and arranged to contact the dovetail joint of the hinge and lock stiles.
Referring to Figs. 2 through 6, lock stile body 46 includes an inner wall 43 and hinge stile body 52 includes an inner wall 49. Further, top rail 34 and bottom rail 36 each include inner walls 35 and 37 respectively. Advantageously, inner walls 35, 37, 43 and 49 define an internal cavity 75.
In accordance with yet another main feature of the present invention, Fig. 8 illustrates first skin 22 with a back side 58 having a plurality of protrusions 60 extending therefrom. In a preferred embodiment, protrusions 60 are spaced a distance A from a top edge 62 of skin 22. Further, a similar distance is incorporated for the bottom end of the skin (not shown). Advantageously, this arrangement allows the second skin back side 58 to be flush against top rail 34 and bottom rail 36 while allowing protrusion 60 to engage slots 40. While a preferred embodiment second skin includes five protrusions, any number or arrangement of protrusions may be incorporated without departing from the spirit and scope of the present invention as claimed. Further, protrusions 60 are illustrated with generally square walls extending from the back side of the skin and a rounded top end. Protrusion 60 may have a varying width as well as any suitable shape so long as they mate with slots 40. Finally, protrusions 60 are also spaced apart a distance B which can also be varied so long as the requirements above are satisfied.
Fig. 9 illustrates top rail 34 being inserted in the direction of arrow 64 to install the top rail on frame 28 along top end 39. An adhesive 66 is placed on inner wall 35 and receiving portion 56 to secure the top rail to lock stile 30. A similar process is completed with respect to hinge stile 32 to secure the other side of top rails 34 to the hinge stile. While the adhesive is described as being placed on inner wall 35, the adhesive may also be placed directly on the hinge and lock stiles.
Fig. 10 is a top view of top rail 34 installed on dovetail joint 38 of lock stile 30.
In particular, dovetail joint 38 is slidingly engaged with receiving portion 56 of top rail 34. Advantageously, this arrangement allows top rail 34 to be secured on lock stile 30 and permit movement only in an upward direction.
Figs. 11-13 illustrate the attachment of first skin 22 and second skin 26 to lock stile 30 as well as locating a foam core 68 between the skins in cavity 75.
Fig. 11 illustrates skins 22 and 26 prepared for installation on lock stile 30, while a similar arrangement is found at hinge stile 32, but not shown. As discussed above, skin 22 includes a back side 58 with protrusions 60 extending away from the skin. The first skin 22 also has a front side 70 which includes a variety of panels as discussed above.
Second skin 26 includes a back side 72 having a plurality of protrusions 60 extending therefrom and a front side 74 opposite back side 72 and also including a plurality of panels.
Fig. 12 illustrates first skin 22 and second skin 26 in the installed position after forcing protrusions 60 within slots 40. Specifically, skin 22 is forced in the direction associated with arrow 76 while skin 26 is forced in the direction associated with arrow 78. In a preferred embodiment and seen in Figs. 12 and 13, adhesive is located along the back side 58 of skin 22 and back side 72 of skin 26 such that adhesive bonds between the back sides 58, 72 and lock stile 30 and a top rail outer surfaces 29A and 29B. Further adhesive is also located within slots 40 and on protrusions 60 such that there is an increased adhesive area at the protrusions. During the installation, skins 22 and 26 are forced in their respective directions until protrusions 60 are fully seated within slots 40. Protrusions 60 and slots 40 may also be arranged such that there is a slight interference fit to ensure that the skins do not become separated from the frame while the adhesive is curing.
Fig. 14 illustrates the top corner of a preferred embodiment door assembly 20.
Top rail 34 is adhesively secured to lock stile 30, while skins 22 and 26 are each adhesively secured to top rail 34 and lock stile 30. Accordingly, the present invention creates a sounder and more secure bound between door skins 22 and 26 and lock stile 30 and hinge stile 32 (not shown) while retaining the traditional look of a standard door.
Having described the structure of the first embodiment, only those portions of the second embodiment which are different than the first embodiment are described in detail. Likewise, similar numerals refer to similar parts throughout the various embodiments.
Fig. 15 and 16 illustrate a second preferred embodiment, with a first skin 80 and a second skin 82. In accordance with yet another main feature of the present invention, skins 80 and 82 have distinct and different outer surfaces 84 and respectively. Further, inner surfaces 85 and 87 of skins 80 and 82 are also distinct from each other. While the second preferred embodiment is shown with six panels 24 on the first skin and two panels 83 on the second skin, any arrangement of first and second skins that have a distinct outer appearance may be utilized.
Advantageously, this allows the purchaser to have a first skin which matches the exterior of the dwelling, while having a second skin facing the interior of the dwelling that again matches a completely different environment than the outside.
Another advantage of the preferred embodiments is the ability to selectively size the door using protrusions 60 and slots 40. Specifically, protrusions 60 may align with only a portion of slots 40, thereby having a portion of the skins hang over the frame. The skin can then be trimmed to reduce the side of the door. The hinge and lock stiles may then include an additional member bolted thereon to ensure a proper door size.
In a second preferred embodiment, frame 88 is composed of six pieces, top rail 34 and bottom rail 36 remaining the same as the previous embodiment. However, lock stile 90 includes a high quality outer piece 92 and a low quality interior piece 94.
Hinge stile 96 also includes a high quality outer piece 98 and a low quality inner piece 100. High quality pieces 92 and 98 both include dovetail joints at the top and bottom portions and define the outer most edges of the frame. High quality pieces 92 and 98 are also thin and incorporated at the ends to provide the appearance of a hard wood or high quality door throughout the frame construction, while reducing costs by incorporating low quality pieces 94 and 100. Further, low quality pieces 94 and 100 include protrusions 40 similar to the first embodiment throughout their length.
Advantageously, incorporating low quality pieces 94 and 100 for the entire length of the slots ensures that machining of the slots is more readily accomplished without a waste of material.
Finally, high quality piece 92 is preferably adhesive secured to low quality piece 94, while high quality piece 98 is also adhesively secured to low quality piece 100.
Accordingly, when the high quality and low quality pieces are attached, they form the lock stile and hinge stile described in the first preferred embodiment in a more cost effective manner.
Having described the structure of the first two embodiments, only those portions of the third embodiment, which are different than the first two embodiments, are described in detail. Likewise, similar numerals refer to similar parts throughout the various embodiments.
Figs. 17-19 illustrate a third preferred embodiment with a first skin 102, a second skin 104, and a frame 106. Frame 106 is generally shaped identical to the first preferred embodiment frame, however the incorporation of the second preferred embodiment frame with high quality and low quality pieces is within the spirit and the scope of present invention as claimed. Further, first skin 102 is arranged similar to first skin 22 in that there are six panels 24. Second skin 104 has three panels 108 in the third preferred embodiment to provide a distinct and different appearance than the first skin. Frame 106 includes a lock stile 110 and a hinge stile 112.
In accordance with one of the main features of the present invention, lock stile 110 and hinge stile 112 (not shown) include a plurality of protrusions 114 extending from both sides of each stile. Further, skins 102 and 104 each include a back side 116 and 118 respectively. A plurality of slots 120 are formed within back sides 116 and 118 so that slots 120 are arranged to receive protrusions 112 of lock stile 110 and hinge stile 112.
As discussed in the first preferred embodiment, installation of the third preferred embodiment skins is similar in that first skin 104 is forced in the direction associated with arrow 122 until protrusions 114 are inserted within slots 120, while the second skin is forced in the direction associated with arrow 124 until protrusions 114 are inserted within slots 120. Once again, this arrangement provides for an increased adhesion contact area as well as an interference fit between the skins and the stiles.
Having described the structure of the preferred embodiments, a preferred method of manufacturing will be described in detail and should be read in light of Figs.
1-19.
Initially, plurality of slots 40 are formed in frame 28, and preferably in lock stile 30 and hinge stile 32. Next, a plurality of protrusions 40 are formed on back side 58 and 72 of the skins. The slots may be formed by machining or any other suitable removable technique. Similarly, protrusions 60 may be formed by removing material with a machining apparatus or by adhesively securing preformed protrusions on the back side of each skin. Alternatively, slots 40 may be formed in the skins, while protrusions 60 may be formed on frame 28 without departing from the spirit of the invention.
Next, adhesive is located on either frame 28 or back side 58 and 72 of skins and 26. The skins are then directed towards the frame such that the protrusions 60 are inserted within the respective slots 40 of the frame. After one side has been inserted, foam core 68 is disposed within the frame or may be placed by blowing foam insulation within the frame.
Frame assembly 28 is formed by machining top rail 34 with receiving portions 56 on each end and bottom rail 36 with the same receiving portions 56. Lock stile 30 and hinge stile 32 each include dovetail joints 38 on each end. The dovetail joints and receiving protrusions are complimentary shaped to ensure a tight and secure fit as well as provide increased contact surface for the adhesive to cure. Frame 28 is finally formed by securing the dovetail joints and receiving portions of the lock stile, hinge stile, top rail and bottom rail with adhesive.
Having described the structure and operation of the first three preferred embodiments, only those portions of the fourth preferred embodiment which are different from the previous embodiments are described in detail. Likewise, similar numerals refer to similar parts throughout the various embodiments.
Figures 20 through 24 illustrate a fourth preferred embodiment door assembly 130. Specifically, fourth preferred embodiment door assembly 130 is similar to the three prior embodiments, with the exception of the lock and hinge stiles. A
lock stile 132 includes an outer member 134 and an inner member 136. A hinge stile 138 includes an outer member 140 and an inner member 142.

In accordance with another main feature of the present invention, lock stile inner member 136 includes a dovetail slot extending the entire length of an outer side wall 146 of the lock stile inner member.
Similarly, hinge stile inner member 142 includes a dovetail slot 148 extending throughout the entire length of an outer side wall 150.
Figure 23 illustrates lock stile 132 with outer member 134 separated from inner member 136. In particular, outer member 134 includes a dovetail protrusion 152 extending inward toward inner member 136. Advantageously, dovetail protrusion extends for at least the entire length of inner member 136 and preferably extends the entire length of outer member 134. Advantageously, this arrangement permits outer member 134 to be composed of a high quality material with a more expensive appearance while the inner member 136 can be composed of a lower quality and less appealing material to reduce cost while still maintaining the door's integrity.
Figure 23A illustrates an alternative embodiment for lock stile 132. In particular, outer member 134 again includes a dovetail protrusion 152, but inner member may include a plurality of components. Specifically, inner member 136 may include an intermediate member 154 located next to an internal member 156. Still further, a secondary intermediate member 158 may be located between intermediate member 154 and internal member 156. In this arrangement, each piece may be composed of a different material and adhesively secured together, or the intermediate and secondary intermediate member may be a single unit and adhesively secured to internal member 156. Advantageously, this arrangement again permits the components to be manufactured of a lower quality or varying quality of materials to reduce the cost while maintaining the integrity of the door with a variety of material densities. Specifically, the intermediate member is preferably denser than the inner member or the internal member, while the outer members are even denser than the intermediate members in a preferred embodiment.
Figures 24 and 24A illustrate the hinge stile of the fourth preferred embodiment.
Figure 24 illustrates hinge stile outer member 140 with a dovetail protrusion extending the entire length of the outer member. As can be seen, the dovetail protrusion 160 is axially aligned with dovetail slot 148 of the hinge stile inner member such that the two are mated along the longitudinal axes. In accordance with another main feature of the present invention, Figure 24A illustrates hinge stile inner member 142 having an intermediate member 162 with the dovetail slot 148 and proximate an internal member 164. Preferably, the internal member 164 is secured to the intermediate member 162 with an adhesive to form the hinge stile inner member 142.
Once again, hinge stile outer member 140 is preferably composed of a high quality material providing a more appealing fit and finish, while the inner members 142, intermediate member 162, and internal member 164 are each composed of a lower quality material. Still further, intermediate member 162 may be composed of a higher quality material than internal member 164 if desired.
Having described the structure of the fourth preferred embodiment, a method of manufacturing will now be described in detail and should be viewed in light of Figures 1 through 24A. Initially, a lock stile outer member is formed with a dovetail protrusion along the entire length of the lock stile outer member and a dovetail slot is machined along an entire length of the lock stile inner member. Further, the hinge stile outer member is formed with a dovetail protrusion along the entire length of the inner portion while the hinge stile inner member is formed with a dovetail slot along the entire length thereof. Next, the lock stile outer member protrusion in the lock stile inner member slot are joined together with an adhesive, while the hinge stile outer member protrusion and the hinge stile inner member slot are joined together with an adhesive.
Next, a top rail and a bottom rail are secured to the lock stile and the hinge stile before II
a front skin and a rear skin are finally secured to the frame. Accordingly, the integration of protrusions and slots may still be incorporated in a manner similar to the procedures detailed above.
While the above method of manufacturing utilizes protrusions on the back side of each skin, it is within the spirit of the scope of the present invention to form protrusions on both sides of the lock and hinge stiles and machine slots in the back side of each skin. Further, a combination of the two may also be used without departing from the spirit of the scope of the invention as claimed. For example, one side of the lock stile may have protrusions, while the opposite side of the same stile may have slots therein. Still further, the lock stile may have protrusions on both ends, and a combination of protrusions and slots while the hinge stile only has slots. Thus, it is seen that any useful combination of slots and protrusions on the stiles and skins may be used without departing from the spirit and scope of the present invention as claimed.
Thus, door assembly 20 provides an increased contact surface area between a door frame and the skins. The door skins are also arranged so that a first skin may have a unique and distinct outward appearance, while the opposing second skin may have a completely different appearance to enable the purchaser to custom fit his/her desired application. Further, a cheaper and more cost effective version of the invention may be incorporated by providing both high quality and low quality wood strategically placed to provide the increased contact surface as well as different skin options. Still further, the outer members may include protrusions joined to the inner members to provide greater strength and integrity while reducing material costs.
It will be evident to one skilled in the art that a variety of changes can be made that are within the spirit and scope of the present invention. For instance, the protrusions may be located on either the skin or the stile, while the slots may also be located on either the skin or stiles. Further, any suitable skin design may be used in combination with any other suitable skin design such that the purchaser has a great deal of flexibility in his/her door skins.
Accordingly, the door assembly is an effective, safe, inexpensive, and efficient device that achieves all of the desired objectives of the invention, provides for eliminating difficulties encountered with prior art devices, systems, methods, and solves problems and obtains new results in the art.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding; but no unnecessary limitations are to be implied therefrom beyond the requirement of the prior art, because such terms are used for descriptive purposes and are intended to be broadly construed.

Advantageously, dovetail protrusion extends for at least the entire length of inner member 136 and preferably extends the entire length of outer member 134. Advantageously, this arrangement permits outer member 134 to be composed of a high quality material with a more expensive appearance while the inner member 136 can be composed of a lower quality and less appealing material to reduce cost while still maintaining the door's integrity.
Figure 23A illustrates an alternative embodiment for lock stile 132. In particular, outer member 134 again includes a dovetail protrusion 152, but inner member may include a plurality of components. Specifically, inner member 136 may include an intermediate member 154 located next to an internal member 156. Still further, a secondary intermediate member 158 may be located between intermediate member 154 and internal member 156. In this arrangement, each piece may be composed of a different material and adhesively secured together, or the intermediate and secondary intermediate member may be a single unit and adhesively secured to internal member 156. Advantageously, this arrangement again permits the components to be manufactured of a lower quality or varying quality of materials to reduce the cost while maintaining the integrity of the door with a variety of material densities. Specifically, the intermediate member is preferably denser than the inner member or the internal member, while the outer members are even denser than the intermediate members in a preferred embodiment.
Figures 24 and 24A illustrate the hinge stile of the fourth preferred embodiment.
Figure 24 illustrates hinge stile outer member 140 with a dovetail protrusion extending the entire length of the outer member. As can be seen, the dovetail protrusion 160 is axially aligned with dovetail slot 148 of the hinge stile inner member such that the two are mated along the longitudinal axes. In accordance with another main feature of the present invention, Figure 24A illustrates hinge stile inner member 142 having an intermediate member 162 with the dovetail slot 148 and proximate an internal member 164. Preferably, the internal member 164 is secured to the intermediate member 162 with an adhesive to form the hinge stile inner member 142.
Once again, hinge stile outer member 140 is preferably composed of a high quality material providing a more appealing fit and finish, while the inner members 142, intermediate member 162, and internal member 164 are each composed of a lower quality material. Still further, intermediate member 162 may be composed of a higher quality material than internal member 164 if desired.
Having described the structure of the fourth preferred embodiment, a method of manufacturing will now be described in detail and should be viewed in light of Figures 1 through 24A. Initially, a lock stile outer member is formed with a dovetail protrusion along the entire length of the lock stile outer member and a dovetail slot is machined along an entire length of the lock stile inner member. Further, the hinge stile outer member is formed with a dovetail protrusion along the entire length of the inner portion while the hinge stile inner member is formed with a dovetail slot along the entire length thereof. Next, the lock stile outer member protrusion in the lock stile inner member slot are joined together with an adhesive, while the hinge stile outer member protrusion and the hinge stile inner member slot are joined together with an adhesive.
Next, a top rail and a bottom rail are secured to the lock stile and the hinge stile before II
a front skin and a rear skin are finally secured to the frame. Accordingly, the integration of protrusions and slots may still be incorporated in a manner similar to the procedures detailed above.
While the above method of manufacturing utilizes protrusions on the back side of each skin, it is within the spirit of the scope of the present invention to form protrusions on both sides of the lock and hinge stiles and machine slots in the back side of each skin. Further, a combination of the two may also be used without departing from the spirit of the scope of the invention as claimed. For example, one side of the lock stile may have protrusions, while the opposite side of the same stile may have slots therein. Still further, the lock stile may have protrusions on both ends, and a combination of protrusions and slots while the hinge stile only has slots. Thus, it is seen that any useful combination of slots and protrusions on the stiles and skins may be used without departing from the spirit and scope of the present invention as claimed.
Thus, door assembly 20 provides an increased contact surface area between a door frame and the skins. The door skins are also arranged so that a first skin may have a unique and distinct outward appearance, while the opposing second skin may have a completely different appearance to enable the purchaser to custom fit his/her desired application. Further, a cheaper and more cost effective version of the invention may be incorporated by providing both high quality and low quality wood strategically placed to provide the increased contact surface as well as different skin options. Still further, the outer members may include protrusions joined to the inner members to provide greater strength and integrity while reducing material costs.
It will be evident to one skilled in the art that a variety of changes can be made that are within the spirit and scope of the present invention. For instance, the protrusions may be located on either the skin or the stile, while the slots may also be located on either the skin or stiles. Further, any suitable skin design may be used in combination with any other suitable skin design such that the purchaser has a great deal of flexibility in his/her door skins.
Accordingly, the door assembly is an effective, safe, inexpensive, and efficient device that achieves all of the desired objectives of the invention, provides for eliminating difficulties encountered with prior art devices, systems, methods, and solves problems and obtains new results in the art.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding; but no unnecessary limitations are to be implied therefrom beyond the requirement of the prior art, because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention is an example, and the scope of the invention is not limited to the exact details shown or described.
Having now described the features, discoveries, and principles of the invention, the manner in which the door frame is constructed and used, the characteristics of the construction, and the advantageous new and useful results obtained; the new and useful structures, devices, elements, arrangement, parts and combinations are set forth in the appended claims.
