This application claims the priority, under 35 U.S.C. §§ 119 and 371, of Australian patent application No. 2010904673, filed Oct. 20, 2010; the prior application is herewith incorporated by reference in its entirety.
Not Applicable
The present invention relates to manufacturing frame assemblies and in particular to a frame assembly for a doorway.
The invention has been developed primarily for use in frame assemblies for doorways and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.
Frame assemblies for doorways generally comprise two vertical sections (upright jambs) and a horizontal section (header jamb) that connects the two upright jambs to form a standard door frame or assembly for installation in a doorway. The upright jambs and the header jamb are generally manufactured and sold with either a single or double rebate depending on whether the door assembly is to have one or two door panels fitted. Once purchased, additional rebates are required to be made at either end of the header jamb to accommodate the upright jambs so that the frame assembly can fit neatly within the doorway. However, such additional header rebates are usually prepared onsite using a saw or chisel which oftentimes leads to unsightly saw or chisel marks in the header jamb that subsequently need to be filled or smoothed to ensure a seamless connection with the corresponding upright jamb.
The upright jambs and the header jamb are typically manufactured as a set with each jamb being of generally a fixed dimension in accordance with those of standard doorways. This presents problems in cases where the doorway is not a standard doorway such that one or more of the jambs in the set have the wrong dimensions and new jambs need to be custom built. The one or more jambs remaining in the set are therefore redundant and often left to waste.
Standard doorways also pose difficulties when large or awkward household items such as, for example, furniture or whitegoods, are to be passed through the doorway. Due to the fixed width of standard doorways, such items may require disassembling or some other form of time-and energy-consuming maneuvering to pass the item through the doorway. In other cases, the doorway may also need to be widened to allow, for example, wheelchair access. In cases where the doorway is to be widened, it is necessary to obtain at least a new header jamb to account for the additional width of the doorway. This presents additional problems, as the new header jamb will again need to have additional header rebates cut to accommodate the existing upright jambs.
The present invention seeks to provide a frame assembly for a doorway which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.
It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.
The invention provides a method for manufacturing frame assemblies and, in particular, to a frame assembly for a doorway that overcome the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type.
Although the invention is illustrated and described herein as embodied in a method for manufacturing frame assemblies and, in particular, to a frame assembly for a doorway, it is, nevertheless, not intended to be limited to the details shown because various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention.
Additional advantages and other features characteristic of the present invention will be set forth in the detailed description that follows and may be apparent from the detailed description or may be learned by practice of exemplary embodiments of the invention. Still other advantages of the invention may be realized by any of the instrumentalities, methods, or combinations particularly pointed out in the claims.
Other features that are considered as characteristic for the invention are set forth in the appended claims. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one of ordinary skill in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting; but rather, to provide an understandable description of the invention. While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward.
According to a first aspect of the present invention, there is provided a frame assembly for a doorway, the doorway being defined by two substantially vertical sides and a substantially horizontal side comprising a header jamb having a top surface, a bottom surface and one or two header jamb rebates, the top surface of the head jamb being adapted for fixedly mounting to the substantially horizontal side of the doorway and the one or two header jamb rebates located on the bottom surface across the length of the header jamb defining a header soffit, and two upright jambs each having an outer surface and a top end, the outer surface of each of the upright jambs being adapted for fixedly mounting to one of the two substantially vertical sides of the doorway, the top end of each of the upright jambs having a slot for receiving a portion of the header soffit such that when assembled the header soffit engages in the slots.
Advantageously, the slot in the top ends of each upright jamb enables the header jamb to be mounted quickly and easily on the upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb to receive the upright jambs as is required with a standard frame assembly for a doorway.
Advantageously, the slot in the top ends of each upright jamb receives a portion of the header soffit such that the top end of the upright jamb substantially abuts the one or two header jamb rebates on the bottom surface of the header jamb.
Advantageously, in the event the doorway is required to be widened, the frame assembly can be easily disassembled, and the same upright jambs repositioned in the widened doorway, such that all that is required is a longer header jamb to be introduced. This is beneficial as the longer header jamb can be mounted quickly and easily on the repositioned upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb.
Advantageously, in the event the doorway is required to be narrowed, the frame assembly can be easily disassembled, and the same upright jambs can be repositioned in the narrowed doorway, such that all that is required is a shorter header jamb to be introduced. This is beneficial as the same header jamb can be shortened and then re-mounted quickly and easily on the repositioned upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb.
Advantageously, the header jamb and the two upright jambs can be provided as a single jamb cut with one or two rebates as is required and then cut onsite to the appropriate lengths of the header jamb and the two upright jambs according to the dimensions of the doorway. This is beneficial as the frame assembly can be manufactured and provided as a single jamb rather than as a set of three separate jambs as is the case with conventional frame assemblies for doorways.
Preferably, each of the upright jambs has an inner surface, a bottom end, and one or two upright rebates in the inner surface extending from the top end to the bottom end, the one or two upright rebates corresponding to the one or two header jamb rebates and having generally the same cross-section.
Preferably, the frame assembly further comprises one or more auxiliary upright jambs disposed between the upright jambs, each of the one or more auxiliary upright jambs having an auxiliary top end, each of the auxiliary top ends having an auxiliary slot for receiving a portion of the header soffit such that when assembled the header soffit engages in the auxiliary slots.
Advantageously, one or more auxiliary upright jambs can be easily introduced to the frame assembly to, for example, divide the frame assembly into two or more openings. This is beneficial if, for example, two or more auxiliary doors are to be installed in the frame assembly, or alternatively, if, for example, an auxiliary door is to be introduced into one of the two or more openings and either a leadlight (not shown) or a solid panel (not shown) is to be installed in the other of the two or more openings.
Advantageously, the auxiliary slot in the auxiliary top end of each of the one or more auxiliary upright jambs receives a portion of the header soffit such that the auxiliary top end of each of the one or more auxiliary upright jambs substantially abuts the one or two header jamb rebates on the bottom surface of the header jamb.
Preferably, each of the auxiliary upright jambs has a side surface, an auxiliary bottom end and one or two auxiliary rebates in the side surface extending from the auxiliary top end to the auxiliary bottom end, the one or two auxiliary rebates corresponding to the one or two header jamb rebates and having generally the same cross-section.
Preferably, the one or two upright rebates of at least one of the upright jambs and the corresponding one or two header jamb rebates define corresponding one or two door recesses.
Advantageously, when the frame assembly is assembled, the one or two upright rebates and the corresponding one or two header jamb rebates having the same cross-section substantially align to define one (door recess on one side of the frame assembly or two door recesses with one on each side of the frame assembly.
Preferably, the one or two auxiliary rebates of at least one of the one or more auxiliary upright jambs and the corresponding one or two header jamb rebates define corresponding one or two auxiliary door recesses.
Advantageously, when the frame assembly is assembled, the one or two auxiliary rebates and the corresponding one or two header jamb rebates having the same cross-section substantially align to define one auxiliary door recess on one side of the frame assembly or two auxiliary door recesses with one on each side of the frame assembly.
According to a second aspect of the present invention, there is provided a door assembly comprising a frame assembly as described in the first aspect of the present invention and one or two doors for location in the respective one or two door recesses when in a closed position.
Advantageously, when the door assembly has a door recess on either side of the frame assembly, a standard door can be located in the auxiliary door recess on a first side of the frame assembly, and an outer screen door can be located in the door recess formed on a second side of the frame assembly.
According to a third aspect of the present invention, there is provided a door assembly comprising a frame assembly as described in the first aspect of the present invention and one or two auxiliary doors for location in the respective one or two auxiliary door recesses when in a closed position.
Advantageously, when the door assembly has an auxiliary door recess on either side of the frame assembly, a standard door can be located in the auxiliary door recess on a first side of the frame assembly, and an outer screen door can be located in the auxiliary door recess formed on a second side of the frame assembly.
Thus, a need exists to overcome the problems with the prior art systems, designs, and processes as discussed above.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements throughout the separate views, which are not true to scale, and which, together with the detailed description below, are incorporated in and form part of the specification, serve to illustrate further various embodiments and to explain various principles and advantages all in accordance with the present invention. Advantages of embodiments of the present invention will be apparent from the following detailed description of the exemplary embodiments thereof, which description should be considered in conjunction with the accompanying drawings in which:
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

According to a first embodiment of the present invention, and as schematically shown in
In this embodiment, the header jamb 15 and the two upright jambs 40, 45 can be provided as a single jamb cut with one or two rebates as required and then cut to the appropriate lengths of the header jamb 15 and the two upright jambs 40, 45 according to the dimensions of the doorway. This is beneficial as the frame assembly 10 can be provided as a single jamb rather than as three separate jambs (the header jamb 15 and the two upright jambs 40, 45) as is the case for standard frame assemblies for doorways. The header jamb 15 in
As shown in
The length of the header jamb 15 is such that each of the respective ends 80, 85 of the header jamb 15 lies flush with the outer surface 50, 55 of the corresponding upright jamb 40, 45. Although, it will be appreciated that in other embodiments, the respective ends 80, 85 of the header jamb 15 may extend beyond the outer surface 50, 55 of the corresponding upright jamb 40, 45 into the corresponding substantially vertical sides of the doorway. In this respect, the header jamb 15 is supported by the two upright jambs 40, 45 and the substantially vertical sides of the doorway.
In this embodiment, in the event the doorway is required to be widened, to, for example, allow for wheelchair access, the frame assembly 10 can be easily disassembled, and one or both of the same upright jambs 40, 45 repositioned in the widened doorway, such that all that is required is a longer header jamb 15 to be introduced. This is beneficial as the longer header jamb 15 can be mounted quickly and easily on the repositioned upright jambs 40, 45 onsite without needing to prepare additional header rebates in the bottom surface 25 of the header jamb 15. Similarly, in the event the doorway is required to be narrowed, the frame assembly 10 can be easily disassembled, and one or both of the same upright jambs 40, 45 can be repositioned in the narrowed doorway, such that all that is required is a shorter header jamb 15 to be introduced. This is beneficial as the same header jamb 15 can be shortened, for example, by cutting with a saw, and then re-mounted quickly and easily on the repositioned upright jambs 40, 45 onsite without needing to prepare additional header rebates in the bottom surface 25 of the header jamb 15.
In this embodiment, each of the upright jambs 40, 45 has an inner surface, as generally indicated by reference numerals 90, 95, a bottom end 100, 105, and one or two upright rebates 110, 110′ in the inner surface 90, 95 extending from the top end 60, 65 to the bottom end 100, 105, the one or two upright rebates 110, 110′ corresponding to the one or two header jamb rebates 30, 30′ and having generally the same cross-section. As shown in
As shown in
In this embodiment, as the header jamb 15 and upright jambs 40, 45 are cut from the same single jamb, the one or two header jamb rebates 30, 30′ and the corresponding one or two upright rebates 110, 110′ have the same cross-section such that when the frame assembly 10 is assembled, the one or two header jamb rebates 30, 30′ and the corresponding one or two upright rebates 110, 110′ substantially align to define either one door recess on one side of the frame assembly 10 or two door recesses with one door recess on each side of the frame assembly 10, depending on the number of header jamb rebates 30, 30′ and upright rebates 110, 110′. Referring specifically to
In this embodiment, the frame assembly 10 further comprises one or more auxiliary upright jambs disposed between the upright jambs 40, 45, each of the one or more auxiliary upright jambs having an auxiliary top end, each of the auxiliary top ends having an auxiliary slot for receiving a portion of the header soffit 35 such that when assembled, the header soffit 35 engages in the auxiliary slots. The one or more auxiliary upright jambs can be easily introduced into the frame assembly 10 to, for example, divide the frame assembly 10 into two or more openings. This is beneficial if, for example, two or more auxiliary doors are to be installed in the frame assembly 10, or alternatively, if, for example, an auxiliary door is to be introduced into one of the two or more openings and either a leadlight (not shown) or a solid panel (not shown) is to be installed into the other of the two or more openings.

In another embodiment, and as shown in
The frame assembly for a doorway provides a number of advantages, including:
The slot in the top end of each upright jamb enables the header jamb to be mounted quickly and easily on the upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb to receive the upright jambs as is required with a standard frame assembly for a doorway.
The slot in the top end of each upright jamb receives a portion of the header soffit such that the top end of the upright jamb substantially abuts the one or two header jamb rebates on the bottom surface of the header jamb.
In the event the doorway is required to be widened, the frame assembly can be easily disassembled, and the same upright jambs repositioned in the widened doorway, such that all that is required is a longer header jamb to be introduced. This is beneficial as the longer header jamb can be mounted quickly and easily on the repositioned upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb.
In the event the doorway is required to be narrowed, the frame assembly can be easily disassembled, and the same upright jambs can be repositioned in the narrowed doorway, such that all is required is a shorter header jamb to be introduced. This is beneficial as the same header jamb can be shortened and then re-mounted quickly and easily on the repositioned upright jambs onsite without needing to prepare additional header rebates in the bottom surface of the header jamb.
The header jamb and the two upright jambs can be provided as a single jamb cut with one or two rebates as is required and then cut onsite to the appropriate lengths of the header jamb and the two upright jambs according to the dimensions of the doorway. This is beneficial as the frame assembly can be manufactured and provided as a single jamb rather than as a set of three separate jambs as is the case with conventional frame assemblies for doorways.
One or more auxiliary upright jambs can be easily introduced to the frame assembly to, for example, divide the frame assembly into two or more openings. This is beneficial if, for example, two or more auxiliary doors are to be installed in the frame assembly, or alternatively, if, for example, an auxiliary door is to be introduced into one of the two or more openings and either a leadlight (not shown) or a solid panel (not shown) is to be installed in the other of the two or more openings.
The auxiliary slot in the auxiliary top end of each of the one or more auxiliary upright jambs receives a portion of the header soffit such that the auxiliary top end of each of the one or more auxiliary upright jambs substantially abuts the one or two header jamb rebates on the bottom surface of the header jamb.
When the frame assembly is assembled, the one or two upright rebates and the corresponding one or two header jamb rebates having the same cross-section substantially align to define one door recess on a first side of the frame assembly or two door recesses with one on each side of the frame assembly.
When the frame assembly is assembled, the one or two auxiliary rebates and the corresponding one or two header jamb rebates having the same cross-section substantially align to define one door recess on one a first side of the frame assembly or two door recesses with one on each side of the frame assembly.
According to a second embodiment of the present invention, and as shown in
In this embodiment, the door assembly 160 can thus be configured to have either one door recess on one side of the frame assembly 10 or two door recesses, with one door recess on each side of the frame assembly 10, depending on the number of header jamb rebates 30, (not shown) and upright rebates 110, 110′. Each of the one or two door recesses is thus configured for location of a door 165 therein.
In this embodiment, at least one of the one or two doors 165 is adapted for hingedly mounting to one of the two upright jambs 40, 45. As shown in
The other of the one or two doors (not shown) can be adapted for hingedly mounting to either the other upright rebate 110′ of the same upright jamb 45 as that used for hingedly mounting the at least one door 165 to, or to the upright rebate 110′ of the other of the two upright jambs 40 associated with the other of the one or two door recesses. It will be appreciated that the other of the one or two doors is hingedly mounted to the upright rebate 110′ of the corresponding upright jamb 40, 45 using a hinge as described above. In both cases, the other of the one or two doors is thus configured for moving about the hinged mounting in an arc between an open position, corresponding to a second side of the frame assembly 10 and the closed position where the other of the one or two doors is located within the other of the one or two door recesses. In this arrangement, for example, a standard door 165 can be received in one of the one or two door recesses on the first side of the frame assembly 10, and an outer screen door can be received in the other of the one or two door recesses formed in the second side of the frame assembly 10. It will be appreciated that the choice of which of the two upright jambs 40, 45, the one or two doors 165 are hingedly mounted to within their respective door recesses may depend on any one of a number of factors, including, but not limited to, user preference, structural design, structural limitations of the immediate vicinity around the door assembly 160.
In this embodiment, the door assembly 160 further comprises a lock (not shown) for releasably locking at least one of the one or two doors 165 in the respective door recess when in the closed position. The lock may be any type of lock known in the locksmith trade for locking doors, including, but not limited to, any one of the following: a mortise lock, a lock bolt, an entry lock, or a deadbolt lock. In one example, the lock is a mortise lock comprising a first lock portion (not shown) such as a lock body located in a mortise (not shown) cut into one of the pair of opposing upright ends 180, 180′ of the at least one door 165, and a complementary second lock portion (not shown) such as a strike plate located in the upright rebate 110 of the corresponding upright jamb 40. The first lock portion and the complementary second lock portion are adapted to releasably engage each other to releasably lock the at least one door 165 in the closed position. The lock further comprises a lock trim such as a door handle (not shown) located in the at least one door 165, the lock trim being operatively connected to the first lock portion and being configurable between a locked position where the first lock portion engages the second lock portion to lock the at least one door 165 when in the closed position, and an unlocked position where the first lock portion releases from the second lock portion to unlock the at least one door 165 and enabling it to move about the hinged mounting to the open position. In another example, the bolt is located in the bottom end 175 of the at least one door 165, and the complementary strike plate is located in the portion of the floor superposed below the at least one door 165. Alternatively, or additionally, the lock may be adapted for releasably locking the at least one door 165 to a portion of the header jamb 15 substantially superposed above the at least one door 165. In this case, the first lock portion is located in the top end 170 of the at least one door 165 and the complementary second lock portion (not shown) is located in the portion of the header jamb 15 superposed above the at least one door 165. The lock increases the security of the doorway when the at least one door 165 remains in the closed position.
In other embodiments, it will be appreciated that the one or two door recesses are not limited to being configured for location of just one door 165 therein, but they may be configured for location of more than one door therein. For example, at least one of the one or two door recesses may be configured for location of a pair of doors (not shown) therein. In this example, each door of the pair of doors is adapted for hingedly mounting to the upright rebate 110, 110′ of a corresponding one of the two upright jambs 40, 45 associated with the at least one of the one or two door recesses. In this arrangement, each door of the pair of doors is thus configured for moving about their respective hinged mounting to the corresponding upright jamb 40, 45 in an arc between an open position and the closed position where each door of the pair of doors is located within the at least one of the one or two door recesses.
According to a third embodiment of the present invention, there is provided a door assembly 160, comprising: a frame assembly 10 as described in the first embodiment of the present invention; and one or two auxiliary doors 185, (not shown) for location in the respective one or two auxiliary door recesses when in a closed position. The one or two auxiliary doors 185 each have a top end 190, a bottom end 195, and a pair of opposing upright ends 200, 200′, located between the top end 190 and the bottom end 195. The one or two auxiliary doors 185 may be any type of auxiliary door, such as, for example, a panel door, a plank door, a batten door, a flush door, an outer screen door, or a molded door. The door assembly 160 can be configured with either one auxiliary door recess on one side of the frame assembly 10 or two auxiliary door recesses, with one auxiliary door recess on each side of the frame assembly 10, depending on the number of header jamb rebates 30, (not shown), auxiliary rebates 150, 150′ and upright rebates 110, 110′ defining the corresponding auxiliary door recesses. The one or more auxiliary upright jambs 125 of the frame assembly 10 divide the frame assembly 10 into two or more openings. This is beneficial if, for example, two or more auxiliary doors are to be installed in the frame assembly 10, or alternatively, if, for example, an auxiliary door is to be introduced into one of the two or more openings and either a leadlight (not shown) or a solid panel (not shown) is to be installed into the other of the two or more openings.
In one embodiment, and as shown in
In other embodiments, it will be appreciated that by introducing two auxiliary upright jambs 125, (not shown), each having one or two auxiliary rebates 150, 150′, into the frame assembly 10 such that their corresponding outer surfaces (not shown) substantially abut one another, the door assembly 160 can be configured with a pair of openings in which each opening can have one or two auxiliary door recesses for receiving one or two respective auxiliary doors 185 when in the closed position.
The door assembly provides a number of advantages. First, when the door assembly has a door recess on either side of the frame assembly, a standard door can be located in the auxiliary door recess on a first side of the frame assembly, and an outer screen door can be located in the door recess formed on a second side of the frame assembly. Second, when the door assembly has an auxiliary door recess on either side of the frame assembly, a standard door can be located in the auxiliary door recess on a first side of the frame assembly, and an outer screen door can be located in the auxiliary door recess formed on a second side of the frame assembly.
