Definitions
- This application relates to a field-installable doorframe including an adjustable spacer and to a method for installing a door frame in a rough opening of a wall.
- Doors used in residential, commercial, and industrial settings help prevent the spread of fire, reduce noise, increase privacy, and provide an aesthetically appealing closure.
- a doorframe must be square and plumb. Squaring a doorframe typically involves ensuring the front faces of the vertical jambs and head jamb are in the same plane, ensuring the vertical jambs are orthogonal to the head jamb, and ensuring that the vertical jambs are parallel, for example. If the doorframe is not square, the door will probably not fit or hang properly and unsightly gaps may appear between the door and doorframe. Plumbing a doorframe essentially involves ensuring that the vertical jambs are parallel to the force of gravity, which aids a properly weighted door to open and close with ease.
- doors and doorframes may take many different forms and can be installed in a number of ways.
- a door may be hinged to a doorframe to allow it to pivot away from the doorway in one direction, but not the other.
- FIG. 1 shows a common residential doorframe 10 having a flat-jamb 20 , applied T-stop 22 , and casing 24 .
- Doorframe 10 is typically installed late in the construction process, such as after gypsum wall board (GWB) or sheetrock 26 has been secured to wooden stud 28 , textured, and painted.
- GWB gypsum wall board
- flat-jamb 20 is positioned adjacent wooden stud 28 on each side of the doorway.
- Gap 30 is left to insert shims (not shown) during the squaring and plumbing process.
- casing 24 is cut to size and a 45-degree miter is usually cut to form a miter joint with the overhead casing (not shown).
- Casing 24 is then installed to conceal gap 30 .
- This type of frame requires many parts to be cut, squared and plumbed in the field.
- the miter joint is difficult to keep tight, so the overall finished quality largely depends upon the skill level of the installer.
- throated frame system 40 manufactured by Washington Hardwoods, LLC of Seattle, Wash., USA is shown in FIG. 2 and in U.S. Patent Application Publication No. US 2003/0037507A1, which is incorporated herein by reference in its entirety.
- This system installs relatively easily to metal studs 42 and offers an abundance of design flexibility compared to the flat jamb and casing detail, but needs to be installed early in the construction process.
- throated frame 44 is secured to metal stud 42 as the walls are being framed. Because other trades are still completing their jobs, care must be taken to ensure throated frame system 40 is not damaged.

- head jamb 54 can first be checked to ensure it is level. If head jamb 54 needs adjustment, strike jamb 60 or hinge jamb 62 can be vertically adjusted, such as by placing shims under the bottom of each, as needed. Next, one or more sides of hinge jamb 62 can be checked to ensure it is plumb using a level or a plumb bob and string. If hinge jamb 62 needs adjustment, adjustable spacers 56 can be fine-tuned.
- driving feature 77 of adjustable spacer 56 is accessible by inserting a tool, such as a flat head screwdriver, into access opening 68 .
- a tool such as a flat head screwdriver
- shaft 78 pushes flange 76 against wooden stud 28 , metal stud 42 , or wood buck 92 causing hinge jamb 62 to move away from the stud.
- shaft 78 will loosen, allowing hinge jamb 62 to be pushed toward the stud.
- Adjustable spacers 56 essentially allow hinge jamb 62 to be adjusted from behind.
- vertical jamb 52 pivots about the structure that joins head jamb 64 to vertical jamb 52 , such as dovetail keys 58 or pocket hole screw 98 , while adjustable spacer 56 is adjusted.
- hinge jamb 62 After hinge jamb 62 has been plumbed, it can be secured by placing screws in securement holes 70 , which may be above and below each access opening 68 . These screws can also be loosened at a later time for additional adjustments.
- strike jamb 60 can be plumbed in a similar manner. Likewise, the same process could be used for head jamb 54 .
- the installer can drill sag holes 72 in each hinge recess 64 .
- a screw such as a three inch drywall screw, could be inserted into sag holes 72 and secured to wall 90 .
- Stop 100 can then be secured to doorframe 50 , such as by using finishing nails. By placing the nails (not shown) about every 16 inches on center, stop 100 should remain stationary upon impact, such as when a door slams into it. Stop 100 can be made from any type of wood, such as hardwood. Finally, the door may be hung to complete the opening.
- Doorframe 50 may be removed from doorway 59 by removing dovetail keys 58 from corresponding dovetail slots 86 and 86 and/or pocket hole screw 98 from pocket hole 96 . Additional components may need to be removed, such as screws inserted into securement holes 70 and sag holes 72 . Once removed from doorway 59 , doorframe 50 may be relocated to another doorway and be reused.
- doorframe 50 may be combined to create any type of architectural doorframe opening.
- doorframe 50 could be used for openings including, a single door, pairs of doors and doors with various sidelight configurations. Although these different configurations would contain different framing profiles, the connections and custom spacers that have been described may still be used.
Abstract
A doorframe kit includes a head jamb for installation over a top portion of a doorway and a vertical jamb adapted to be joined to the head jamb and extend along a surface of a wall adjacent the doorway. The doorframe kit may include an adjustable spacer having a shaft adjustably engaged with a retaining member. The retaining member may be fixedly mounted to the vertical jamb at an adjustment location spaced below the head jamb. The shaft may be selectively movable relative to the retaining member to project outwardly from the vertical jamb and bear against the surface of the wall, when in use, to thereby define a standoff distance between the vertical jamb and the wall at the adjustment location. Inserting a tool into an access opening formed in the vertical jamb allows the tool to drive the adjustable spacer outwardly thereby increasing the standoff distance.
Description
- This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 60/743,926, filed Mar. 29, 2006, which is hereby incorporated by reference in its entirety.
- This application relates to a field-installable doorframe including an adjustable spacer and to a method for installing a door frame in a rough opening of a wall.
- Doors used in residential, commercial, and industrial settings, among other things, help prevent the spread of fire, reduce noise, increase privacy, and provide an aesthetically appealing closure. To accomplish these and other objectives, a doorframe must be square and plumb. Squaring a doorframe typically involves ensuring the front faces of the vertical jambs and head jamb are in the same plane, ensuring the vertical jambs are orthogonal to the head jamb, and ensuring that the vertical jambs are parallel, for example. If the doorframe is not square, the door will probably not fit or hang properly and unsightly gaps may appear between the door and doorframe. Plumbing a doorframe essentially involves ensuring that the vertical jambs are parallel to the force of gravity, which aids a properly weighted door to open and close with ease.
- Depending on their purpose, doors and doorframes may take many different forms and can be installed in a number of ways. For example, a door may be hinged to a doorframe to allow it to pivot away from the doorway in one direction, but not the other.
FIG. 1 shows a commonresidential doorframe 10 having a flat-jamb 20, applied T-stop 22, andcasing 24. Doorframe 10 is typically installed late in the construction process, such as after gypsum wall board (GWB) orsheetrock 26 has been secured towooden stud 28, textured, and painted. During installation, flat-jamb 20 is positioned adjacentwooden stud 28 on each side of the doorway.Gap 30 is left to insert shims (not shown) during the squaring and plumbing process. After flat-jamb 20 is secured towooden stud 28,casing 24 is cut to size and a 45-degree miter is usually cut to form a miter joint with the overhead casing (not shown). Casing 24 is then installed to concealgap 30. This type of frame requires many parts to be cut, squared and plumbed in the field. In addition, the miter joint is difficult to keep tight, so the overall finished quality largely depends upon the skill level of the installer. - Metal studs are common in commercial and some residential applications. While metal framing offers advantages, such as low cost, dimensional consistency, and resistance to environmental conditions, it is more difficult to position and realign doorframes once they have been secured to a metal stud. A throated
frame system 40 manufactured by Washington Hardwoods, LLC of Seattle, Wash., USA is shown inFIG. 2 and in U.S. Patent Application Publication No. US 2003/0037507A1, which is incorporated herein by reference in its entirety. This system installs relatively easily tometal studs 42 and offers an abundance of design flexibility compared to the flat jamb and casing detail, but needs to be installed early in the construction process. Generally,throated frame 44 is secured tometal stud 42 as the walls are being framed.

After the hinge is attached to hingejamb 62, a door (not shown) can be hung from the hinges. In one embodiment, one ormore sag holes 72 are formed in hinge recess 64 so that a sag hole screw may be installed to add rigidity and help prevent the door from sagging over time. - As described in more detail with respect to
FIGS. 7-9 , one or moreadjustable spacers 56 may be provided to help square andplumb doorframe 50. An access opening 68, such as a T-nut hole, may be formed inhinge jamb 62 at anadjustment location 69 and in alignment withadjustable spacer 56. As described in more detail below,access opening 68 may be sized to accommodate a tool for adjusting a position of the hinge jamb relative tosurface 61 ofwall 90. One or more securementholes 70 can be formed inhinge jamb 62. In the embodiment shown inFIG. 3 , twoaccess openings 68 are formed nearhinge recesses 64 to receive twoadjustable spacers 56. In addition, twosecurement holes 70 are formed proximate each of theaccess openings 68. Securement holes 70 can be vertically and laterally offset from each other for maximum stability and may also be countersunk to hide a screw head (not shown). Securement screws inserted into securement holes 70 help fix a standoff distance between hinge jamb 62 andwall 90.Access openings 68 and securement holes 70 may also be formed instrike jamb 60 and head jamb 54. Some or all ofaccess openings 68, securement holes 70, or sag holes 72 may be formed by the manufacturer, the installer or by a combination of the two. - When the door is closed, one side will abut strike
jamb 60 and a latching mechanism (not shown) could secure the door in place. Head jamb 54 is sized to fit the door and helps maintain the relative position of thetop portion 66 ofdoorframe 50. According to one embodiment, head jamb 54 has a length of thirty-six inches and a height of one and a half inches, and strike and hingejambs doorframe 50 can be sized to fit any size opening. For example,doorframe 50 could be sized to fit a single door or double hung door of various dimensions. - Referring now to
FIG. 4 , an enlarged pictorial view of the upper right hand corner ofdoorframe 50 ofFIG. 3 is shown. Dovetail slots (FIGS. 5A , 5B, 6A, and 6B) 86 and 86′ may be formed in abutting portions ofvertical jamb 52 and head jamb 54. Upon installing adouble dovetail key 58 intodovetail slots vertical jamb 52 and head jamb 54 are pulled together.Dovetail keys 58 may be used to assembledoorframe 50 in the field, such as when head jamb 54 andvertical jamb 52 are positioned indoorway 59. In addition,dovetail keys 58 may help keep doorframe 50 square and plumb. - With reference to
FIGS. 5A , 5B, 6A and 6B, the general construction of strike and hingejambs FIG. 5A shows a top view ofvertical jamb 52 whileFIG. 5B shows a side view ofvertical jamb 52.FIG. 6A shows a side view of head jamb 54 whileFIG. 6B shows a bottom view ofhead jamb 54.Solid wood casings cores recess 83 may be formed invertical jamb 52 by selectingsolid wood casings 80 having a depth greater than that ofcore 82. In one embodiment,recess 83 is sized to receive a portion ofwall 90. Likewise, arecess 83′ may be formed in head jamb 54 by selectingsolid wood casings 80′ having a height greater than that ofcore 82′. In one embodiment, recesses 83 and 83′ help define internal surfaces ofvertical jamb 52 and head jamb 54, respectively. For example, the internal surface ofvertical jamb 52 may facesurface 61 ofwall 90. Likewise, the internal surface of head jamb 54 may face a surface ofwall 90 near the top portion ofdoorway 59. Accordingly, the generally U-shaped surfaces surrounding the perimeter ofrecesses vertical jamb 52 and head jamb 54, respectively, such as those surfaces that are interposed betweendoorframe 50 andwall 90. The other surfaces ofvertical jamb 52 and head jamb 54 may be considered external surfaces, such as those surfaces that are not interposed betweendoorframe 50 andwall 90. For example, dovetailslots vertical jamb 52 and head jamb 54, respectively. Likewise,pocket hole 96 is shown formed in an external surface ofhead jamb 54. -
Solid wood casings Cores Class 1 Underwriters Laboratories classification.Solid wood casings cores solid wood casings cores - These parts may then be milled in a molder and profiled to the finished dimensions. For example, recesses 83 and 83′ may be formed to run along surfaces of
vertical jamb 52 and head jamb 54 that facewall 90. By way of another example, dovetailslots jambs dovetail key 58. In one embodiment,dovetail slots solid wood casings relief 88 can be formed in the top portion of each the strike and hingejambs doorframe 50 aroundwall 90 proximate head jamb 54. The parts can then be finish sanded, such as with 150 grit sandpaper, cut to length, prepared for hardware, assembled and possibly finished with a stain.FIGS. 5B and 6A illustratedovetail slots vertical jamb 52 and head jamb 54 according to one embodiment. Afterdovetail slots 86 ofvertical jamb 52 are aligned withslots 86′ of head jamb 54,dovetail keys 58 may be installed therein to securevertical jamb 52 tohead jamb 54, as shown inFIG. 4 . - With reference to
FIGS. 7 , 8, and 9, anadjustable spacer 56 may include ashaft 78 adjustably engaged with a retainingmember 74, such as a T-nut. In one embodiment,shaft 78 is selectively movable relative to retainingmember 74 to project outwardly fromvertical jamb 52, such as strike jamb 60 or hinge jamb 62, and bear againstsurface 61 ofwall 90, when in use, to thereby define a standoff distance betweenvertical jamb 52 andwall 90 at anadjustment location 69.Adjustable spacer 56 may be installed in access opening 68 (FIG. 3 ) and be used to help square and plumbdoorframe 50, possibly without using wood shims and without removingdoorframe 50 from the rough opening inwall 90. - Referring now to
FIG. 7 , retainingmember 74 may be set in access opening 68 from the back of thedoorframe 50. For example, one ormore barbs 75 of a T-nut may be pounded into the material ofdoorframe 50 with a hammer to hold the T-nut in place. In one embodiment, the T-nut is a ½ inch T-nut having at least onebarb 75 and threads sized to fit corresponding threads formed onshaft 78. However the T-nut may have any number of barbs 75 (or the barbs may be omitted), have any dimension or shape, and can accept any thread count (TPI) or thread pitch size.Shaft 78 can be threaded into the T-nut to help square and plumbdoorframe 50. Threadingshaft 78 into retainingmember 74 facilitates a two-way adjustment. For example, rotatingshaft 78 in one direction increases a distance between aflange 76 and retainingmember 74, while rotatingshaft 78 in an opposite direction decreases the distance. Retainingmember 74 may include other components and take other forms to accomplish a similar two-way adjustment. -
Adjustable spacer 56 may also include a one-way adjustment betweenshaft 78 and retainingmember 74. According to another embodiment, retainingmember 74 may include a ratcheting device. For example,shaft 78 may include a radially deformable pin that engages a toothed interior surface of retainingmember 74. Asshaft 78 is pushed toward wall 90 (FIG. 9 ), the pin deforms inwardly to engage the next tooth. A two-way adjustment is possible by including a releasing mechanism onshaft 78 that allowsshaft 78 to be moved in an opposite direction. For example, a trigger may be provided onshaft 78 that causes a spring loaded pin to deform inwardly while the trigger is depressed and extend outwardly when the trigger is released. By way of another example,shaft 78 may include ridges that mesh with corresponding ridges on retainingmember 74. The ridges on retainingmember 74,shaft 78, or both may be formed of an elastomeric material that allowshaft 78 to be held in retainingmember 74 while allowing a relative position ofshaft 78 and retainingmember 74 to be adjusted by applying sufficient force. - Referring now to
FIG. 8 shaft 78 may include a drivingfeature 77 on one end andflange 76 on the other end.Flange 76 may have a smoothsurface facing wall 90. This may help flange 76 to rotate freely as it presses againstwall 90. In one embodiment,flange 76 has a two inch diameter and has a thickness of 1/32 inch. However, other sizes and dimensions are possible depending on the application.Flange 76 could be stamped from sheet metal but can also be formed using any manufacturing process, such as die casting, cold forging, or laser cutting, by way of example. In oneembodiment shaft 78 has a 5/16 inch diameter and a length of ¾ inch. However, other sizes and dimensions are possible.Shaft 78 may be threaded with a thread count (TPI) or thread pitch sized to fit threads of retainingmember 74. Drivingfeature 77 allows a tool (not shown) to rotateshaft 78. Drivingfeature 77 may be recessed or can project away fromshaft 78. In oneembodiment driving feature 77 is a slot sized to receive a flat head screwdriver. Other recessed forms of drivingfeature 77 include notches, sockets, and cavities, for example, sized to receive a driver tool of corresponding size and shape, such as a flat head screwdriver, a Phillips head screw driver or hex driver, for example. Drivingfeature 77 may alternatively project away fromshaft 78, in which case the driver tool would be designed to receive the projection, such as a hex driver or socket wrench, for example. In another embodiment,flange 76 may be a thumbwheel accessible from a front or rear face ofdoorframe 50. This may allow theadjustable spacer 56 to be adjusted without using a tool inserted into access opening 68 and allow access opening 68 to be eliminated.Flange 76 andshaft 78 may be formed from a single piece of material or can be secured together, such as by welding or using a bolt. Whileflange 76 andshaft 78 can be made from metal, such as steel, copper, or aluminum, they may also be made from other materials, such as plastic. - Referring now to
FIG. 9 ,wall 90 is shown withmetal stud 42,sheetrock 26, andwood buck 92 secured together according to a preferred embodiment. Beforedoorframe 50 is installed,sheetrock 26 can be textured and painted. In addition,wood buck 92 can be secured to themetal studs 42 that surround the perimeter of the doorway. Furthermore,wall 90 may be constructed from different materials, such as GWB, drywall, paneling, plastic, metal, or wooden studs, or could be a bulkhead or partition of a ship or recreational vehicle.FIG. 9 also shows one embodiment of an assembleddoorframe 50.Solid wood casings 80,core 82, and faceveneer 84 can all be secured together. Retainingmember 74 can be inserted and secured inaccess opening 68. In addition,shaft 78 can be threaded into retainingmember 74 to formadjustable spacer 56.Flange 76 is interposed betweenwall 90 and retainingmember 74 and is operable to bear againstwall 90 to increase a standoff distance betweenvertical jamb 52 andwall 90. -
Manufacturing doorframe 50 may include forming a joining structure in head jamb 54 to facilitate joiningvertical jamb 52 to an end ofhead jamb 54. For example, dovetailslots 86′ (FIG. 6A ) may be formed in a portion of head jamb 54 that abutsvertical jamb 52 and dovetail slots 86 (FIG. 5B ) may be formed in a portion ofvertical jamb 52 that abutshead jamb 54. As previously discussed,dovetail slots vertical jamb 52 and head jamb 54 are pulled together bydovetail key 58. By way of another example, and as described in more detail with reference toFIG. 10 , apocket hole 96 can be formed in head jamb 54 proximate a portion of head jamb 54 adapted to abutvertical jamb 52 such that apocket hole screw 98 inserted intopocket hole 96 locks head jamb 54 tovertical jamb 52. - As previously described,
adjustable spacer 56 may includeshaft 78 adjustably engaged with retainingmember 74. Attachingadjustable spacer 56 tovertical jamb 52 may include mounting retainingmember 74 tovertical jamb 52 at adjustment location 69 (FIG. 3 ). An access opening 68 may be formed invertical jamb 52 so that access opening 68 is in alignment withshaft 78.Access opening 68 may be sized to admit a tool for drivingshaft 78 relative to retainingmember 74 so that a position ofvertical jamb 52 relative to surface 61 ofwall 90 is adjustable. - While there are many ways to install
doorframe 50, the following is a method according to one embodiment. Initially, strike jamb 60, hinge jamb 62, and head jamb 54 are moved into position. Strike jamb 60 and hinge jamb 62 are stood up and placed over the wall. For example, recesses 83 and 83′ may accept a portion ofwall 90. A screw can then be temporarily inserted into one of the securement holes 70 (FIG. 3 ) to holdstrike jamb 60 and hinge jamb 62 in place. Head jamb 54 can be placed over the wall and held in place with two screws, one screw on each end in one of the securement holes 70. Strike jamb 60, hinge jamb 62, and head jamb 54 can then be joined together, such as with fasteners. - In one embodiment, strike jamb 60, hinge jamb 62, and head jamb 54 are joined by inserting
dovetail keys 58 into correspondingdovetail slots FIGS. 3 and 4 . As the two parts are held together (such as strike jamb 60 and head jamb 54 or hinge jamb 62 and head jamb 54),dovetail keys 58 can be tapped into place. While in oneembodiment dovetail keys 58 are molded from plastic, any material can be used, such as wood or metal, for example. In addition, even thoughdouble dovetail keys 58 are shown as having two dovetail tenons sharing a common surface,dovetail keys 58 can take other shapes.Dovetail keys 58 may be designed to grip and pull the two parts (such as strike jamb 60 and head jamb 54 or hinge jamb 62 and head jamb 54) together. Once installed, a tensile force transmitted throughdovetail keys 58 helps secure the parts together. Other devices may also be used to accomplish the same objective. For example, a single dovetail may be formed on a portion ofvertical jamb 52 that abutshead jamb 54 and a dovetail slot may be formed on a portion of head jamb 54 that abutsvertical jamb 52. Oncevertical jamb 52 is positioned indoorway 59, head jamb 54 may be installed from below so that the single dovetail on thevertical jamb 52 is inserted into the dovetail slot onhead jamb 54. - In another embodiment, strike jamb 60, hinge jamb 62, and head jamb 54 are joined by inserting a pocket hole screw 98 (
FIG. 10 ) into apocket hole 96 formed inhead jamb 54.Pocket hole 96 can be formed in the center of head jamb 54 so it will be covered bystop 100. However, more than onepocket hole 96 could be formed in other locations of head jamb 54 for additional reinforcement. In addition, pocket holes 96 could be formed in strike jamb 60 orhinge jamb 62. Pocket hole screws 98 help lock the joints. This process could be used at each joint or anywhere two pieces of framing material need to be joined together.Pocket hole screw 98 may be used in addition to dovetailkeys 58 to provide additional reinforcement to help keep the parts locked together. - Once strike jamb 60, hinge jamb 62, and head jamb 54 are moved into position and joined together,
doorframe 50 can be squared, plumbed and secured to wall 90. Many different methods may be used to square and plumbdoorframe 50. For example, head jamb 54 can first be checked to ensure it is level. If head jamb 54 needs adjustment, strike jamb 60 or hinge jamb 62 can be vertically adjusted, such as by placing shims under the bottom of each, as needed. Next, one or more sides of hinge jamb 62 can be checked to ensure it is plumb using a level or a plumb bob and string. If hinge jamb 62 needs adjustment,adjustable spacers 56 can be fine-tuned. In one embodiment, drivingfeature 77 ofadjustable spacer 56 is accessible by inserting a tool, such as a flat head screwdriver, into access opening 68. By rotatingadjustable spacer 56,shaft 78 pushes flange 76 againstwooden stud 28,metal stud 42, orwood buck 92 causing hinge jamb 62 to move away from the stud. By rotatingadjustable spacer 56 in the opposite direction,shaft 78 will loosen, allowing hinge jamb 62 to be pushed toward the stud.Adjustable spacers 56 essentially allow hinge jamb 62 to be adjusted from behind. In one embodiment,vertical jamb 52 pivots about the structure that joins head jamb 64 tovertical jamb 52, such asdovetail keys 58 orpocket hole screw 98, whileadjustable spacer 56 is adjusted. After hinge jamb 62 has been plumbed, it can be secured by placing screws in securement holes 70, which may be above and below each access opening 68. These screws can also be loosened at a later time for additional adjustments. After hinge jamb 62 has been plumbed, strike jamb 60 can be plumbed in a similar manner. Likewise, the same process could be used forhead jamb 54. - For additional rigidity and to help keep the door in place and eliminate door sag over time, the installer can drill sag holes 72 in each
hinge recess 64. A screw, such as a three inch drywall screw, could be inserted into sag holes 72 and secured to wall 90. Stop 100 can then be secured todoorframe 50, such as by using finishing nails. By placing the nails (not shown) about every 16 inches on center, stop 100 should remain stationary upon impact, such as when a door slams into it. Stop 100 can be made from any type of wood, such as hardwood. Finally, the door may be hung to complete the opening. -
Doorframe 50 may be removed fromdoorway 59 by removingdovetail keys 58 from correspondingdovetail slots pocket hole screw 98 frompocket hole 96. Additional components may need to be removed, such as screws inserted into securement holes 70 and sag holes 72. Once removed fromdoorway 59,doorframe 50 may be relocated to another doorway and be reused. - While various embodiments of
doorframe 50 have been herein described, strike jamb 60, hinge jamb 62, and head jamb 54 may be combined to create any type of architectural doorframe opening. For example,doorframe 50 could be used for openings including, a single door, pairs of doors and doors with various sidelight configurations. Although these different configurations would contain different framing profiles, the connections and custom spacers that have been described may still be used. - It will be obvious to those having skill in the art that many changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention. The scope of the present invention should, therefore, be determined only by the following claims.
