Abstract
A coping jig for guiding a router in cutting the end of a section of decorative trim, preferably for creating an inside corner. The coping jig includes a stationary molding stage that receives a section of molding to be cut. A template platform is mounted above the molding stage by a plurality of resilient mounting members. The resilient mounting members allow the angle of the template platform to change relative to the molding stage. The template platform includes at least one template having a trim pattern formed on an edge surface of the template. The trim pattern is used to guide the router in cutting the molding positioned between the template and the molding stage.
Description
- This application is based on and claims priority from provisional application Ser. No. 60/188,619 filed on Mar. 13, 2000.
- The present invention relates to a coping jig for use in woodworking. More specifically, the present invention relates to a coping jig having removable pattern templates that are usable in guiding the cutting path of a router to form a desired end shape for forming an inside corner from decorative molding.
- Decorative molding is used in the construction industry as finished trim on a wall adjacent either the floor or ceiling or between the floor and ceiling as a “chair rail”. Typically, the decorative molding has an irregular cross-section including a series of ribs and curved recesses which form an aesthetically pleasing design for the molding.
- When the molding along a wall meets at an inside corner of a room, a finish carpenter is required to hand carve or use a coping saw to form an end of the molding such that one section of molding mates against the opposing section on the perpendicular wall. Merely cutting the molding at a 45° angle does not form a clean corner due to the irregular cross-section of typical decorative molding. The process of cutting the end of one section of molding requires the carpenter to trace the profile of the molding onto the end of the molding to be cut and repeatedly test the piece against the molding already extending into the corner. In a large house with a substantial amount of molding, or when fitting an intricate molding, this process can significantly increase the amount of time required to fully trim out a house with decorative molding.
- The procedure of coping molding is an exacting process, requiring a high degree of care and the skills of an experienced carpenter. Moreover, the process is time-consuming. As each corner requires a piece of molding to have a negative image of the profile of the molding cut into its end and checked for fit and, quite often, modified one or more times, coping creates high demands on the skilled labor resources.
- Currently, several coping jigs are available for directing the travel of a router to create the desired profile in a piece of molding, such as shown in the Dickey et al. U.S. Pat. No. 5,094,279, the Sanger et al. U.S. Pat. No. 5,667,001 and the Darling U.S. Pat. No. 5,893,402. Although each of these patents uses some type of pattern to guide the bit of a router in forming the edge surface of a piece of trim, each of these devices is cumbersome and requires generally large pieces of equipment that must be independently supported by a work table or mounted to some type of support surface in order to operate. Further, each of these devices requires a complicated guide plate assembly to guide the router along the desired path of the molding.
- Therefore, it is an object of the present invention to provide a coping jig that is easy to operate and self-contained such that it can be used at a work site. Further, it is an object of the present invention to provide a coping jig that angles the plane of the router to create a back cut in the section of molding being cut. Further, it is an object of the present invention to provide a coping jig that allows for easy removal and creation of templates to create the desired cut on the section of molding. Additionally, it is an object of the present invention to provide a coping jig that securely holds a section of molding in place during the cutting process.
- The present invention is a coping jig that is used for guiding a router in making a precision cut along an end of a section of molding such that the molding can be used to form an inside corner.
- The coping jig of the present invention includes a stationary base having a pair of sidewalls joined together by a generally flat, horizontal molding stage. The molding stage is positioned to support a section of decorative molding to be end cut by a router. The molding stage includes a stop rail extending along one of its side edges. The stop rail is used to contact and prevent movement of a section of molding to be cut by the router during use of the coping jig.
- The base further includes a pair of clamping blocks that extend through the top surface of the molding stage. Each of the clamping blocks is movable toward and away from the stop rail such that the clamping blocks can be adjusted to securely hold a section of molding positioned on the molding stage between the stop rail and the clamping block.
- The coping jig further includes a template platform that is mounted above the molding stage. The template platform includes a pair of parallel, spaced side rails that are joined to each other by a top plate. The template platform extends between a first end and a second end. The template platform is constructed to receive a template on either its first end or second end, depending upon the requirements of the type of molding being cut.
- The template platform is mounted above the molding stage of the base by a plurality of resilient mounting members. The mounting members create an open space between the molding stage and the template platform for receiving a section of molding to be end cut. The resilient mounting members allow the vertical position of the template platform to change relative to the stationary molding stage. Additionally, the resilient mounting members allow the angular orientation of the template platform relative to the molding stage to change.
- A pair of locking members are positioned between the sidewalls of the base and the side rails of the template platform. The locking members are each operable to secure the template platform at a desired angle relative to the stationary base. Preferably, the locking members include a handle that allow the user to tighten the locking members and secure the template platform at its desired angular position.
- The template platform includes at least one template having the trim pattern for the decorative molding formed being end cut along one of its edge surfaces. The trim pattern formed on the template allows the router to follow the edge surface of the template while making an identical cut in a section of molding positioned beneath the template. Each of the templates is removable from the template platform and can be reversed and attached to the opposite end of the template platform.
- Initially, a pattern section of molding is created by hand or other means and is positioned within the coping jig beneath an uncut, blank template. Once the pattern section of molding is secured within the coping jig, the router is used to follow the end pattern on the pattern section while cutting the identical trim pattern into the blank template positioned above the pattern section of molding. Once the trim pattern has been cut into the template, the pattern section of molding is removed from the jig.
- Once the trim pattern has been formed on the template, the coping jig can be used to cut the desired end pattern onto uncut sections of molding. During creation of the end cut on a section of molding, the template platform is positioned at a slight angle relative to the molding stage such that a back cut is formed on the end of the decorative molding.
- The templates used to create the end cuts in a section of molding include a pair of edge surfaces that can each include a separate trim pattern. In this manner, a single template can be used to create an end cut on multiple types of decorative molding. Additionally, each of the templates is reversible such that a single template can be used to cut both the right and left end of a section of molding.
- Various other features, objects and advantages of the invention will be made apparent from the following description taken together with the drawings.

- Referring first to FIG. 1, thereshown is the coping
jig 10 of the present invention. Copingjig 10 is useful in guiding a router to make an end cut in a section of decorative molding. The copingjig 10 is particularly useful in forming an inside corner between sections ofdecorative molding 12, as shown in FIG. 8. As illustrated in FIG. 8, one piece of thedecorative molding 12 extends into thecorner 14, while the perpendicular section ofdecorative molding 12 includes a negative image of the outer profile of the decorative molding cut into its end. The negative image of the outer profile of the decorative molding allows for a smooth and tight fit between the sections of decorative molding to create a desirable appearance for theinner corner 14, as illustrated in FIG. 8. - Referring now to FIGS. 1 and 2, the coping
jig 10 of the present invention includes astationary base 16 having a pair ofsupport flanges 18 that extend along the entire length of the copingjig 10. Each of thesupport flanges 18 includes a pair of mountingholes 20 that allow the copingjig 10 to be securely mounted to a work surface, if desired. Referring now to FIG. 2, thebase 16 includes a pair of spaced,parallel sidewalls 22 that are joined to each other by a generallyhorizontal molding stage 24. Themolding stage 24 and the pair ofsidewalls 22 are preferably formed as an integral member from aluminum. Themolding stage 24 includes a horizontal flattop surface 26 that is used to support a section of molding, as shown in phantom in FIG. 2. - As illustrated in FIG. 2, the
base 16 includes astop rail 28 that extends along the entire length of thebase 16. Thestop rail 28 protrudes above thetop surface 26 of themolding stage 24. Thestop rail 28 is used to contact an edge of the molding when the molding is positioned on the molding stage, as illustrated in phantom in FIG. 2. - Referring now to FIG. 1, the mounting
stage 24 includes a pair ofopen channels 30 that extend across the width of themolding stage 24. Thechannels 30 extend completely through themolding stage 24 and allow aclamping block 32 to extend through themolding stage 24 and protrude above thetop surface 26, as best illustrated in FIGS. 2 and 3. - As shown in FIG. 2, each of the clamping blocks32 is threadedly received upon an
adjustment shaft 34. Theadjustment shaft 34 includes a length of external threads that interact with a threaded bore formed in theclamping block 32. Each of theadjustment shafts 34 is rotatably supported between the pair of spacedsidewalls 22 and includes anadjustment knob 36. Theadjustment knob 36 extends externally from thebase 16 and can be grasped by a user and rotated in either the clockwise or counter-clockwise direction to move theclamping block 32 toward and away from thestop rail 28, as illustrated byarrows 38 in FIG. 2. The use of theadjustment knob 36 and clampingblocks 32 force the edge of themolding 12 into contact with thestop rail 28 such that the section ofmolding 12 can be securely supported along thetop surface 26 of themolding stage 24. - Referring back to FIG. 2, the coping
jig 10 further includes atemplate platform 40 that is positioned above thebase 16, as best illustrated in FIG. 2. Thetemplate platform 40 includes a pair of side rails 42 that are spaced apart from each other by the width of themolding stage 24. Aninner surface 47 of eachside rail 42 contacts anouter surface 49 of thesidewall 22 to guide the vertical movement of thetemplate platform 40 relative to thebase 16. - The side rails42 each extend between a
first end 46 and asecond end 48 of theplatform 40, as illustrated in FIG. 1. As can be seen in FIG. 1, the length of thetemplate platform 40 is greater than the length of thebase 16, the significance of which will be apparent in the description below. - As can be seen in FIGS. 1 and 3, a
top plate 50 is connected between the pair of spaced side rails 42 and 44. Thetop plate 50 is preferably a section of clear acrylic that is attached between the side rails by plurality of mounting screws. - In addition to the
top plate 50, thetemplate platform 40 includes afirst template 52 mounted to the first end of thetemplate platform 40 and asecond template 54 mounted to thesecond end 48 of the template platform. In the embodiment of the invention illustrated in FIG. 1, each of thetemplates second templates screw connectors 55, as illustrated in FIG. 3. The ease of removing and replacing thetemplates jig 10 of the present invention to be configured in various manners, the significance of which will be discussed in detail below. - In the preferred embodiment of the invention, each of the
templates top surface 26 of themolding stage 24. - Referring back to FIG. 2, the
template platform 40 is supported above thebase 16 by four resilient mountingmembers 56, one of which is positioned near each of the four corners of thetemplate platform 40. The resilient mountingmembers 56 creates anopen channel 57 defined by thetop plate 50, the side rails 42 and themolding stage 24. In the preferred embodiment of the invention, theopen channel 57 has a height of 1½″ such that the copyingjig 10 be used to cut molding up to 1½″ thick. - The resilient mounting
members 56 allow thetemplate platform 40 to move relative to thestationary base 16, as illustrated by the arrows 61 in FIG. 3. For example, if pressure is placed on thetemplate platform 40 near itsfirst end 46, thefirst end 46 moves downward such that the angle of thetemplate platform 40 relative to thestationary molding stage 24 changes. Likewise, if pressure is applied near thesecond end 48, thetemplate platform 40 changes its orientation in the opposite direction relative to thestationary molding stage 24. - Referring back to FIG. 2, each of the resilient mounting
members 56 includes a mountingpost 58 that is received at one end in thesupport flange 18 of thebase 16. The opposite end of the mountingpost 58 is received within anopen channel 60 formed in theside rail 42. The mountingpost 58 is freely movable within theopen channel 60 such that the vertical position of thetemplate platform 40 relative to themolding stage 24 can be changed. - The resilient mounting
member 56 further includes aspring 62 that surrounds the mountingpost 58 and is entrapped between thelower edge 64 of eachside rail 42 and the top surface of eachsupport flange 18. Thespring 62 provides the resiliency necessary to permit thetemplate platform 40 to move in the directions illustrated by the arrows 61 in FIG. 3. - Referring now to FIGS. 1 and 2, the coping
jig 10 further includes a part of locking members positioned on opposite sides of the copingjig 10. Each of the lockingmembers 64 extends through a lockingflange 66 that depends from each of the side rails 42, as illustrated in FIGS. 2 and 3. The lockingmembers 64 each include a threadedshaft 68 that passes through both the lockingflange 68 and thesidewall 22 ofstationary base 16. The threadedshaft 68 includes ahandle 70 that allows the user to tighten and loosen the lockingmember 64. - When the locking
member 64 is sufficiently lose, thetemplate platform 40 can compress thesprings 62 and move in the directions illustrated by the arrows 61 in FIG. 3. When thetemplate platform 40 is moved into its desired location, each of the lockingmembers 64 can be tightened to secure thetemplate platform 40 at the desired angle relative to the fixedmolding stage 24. - Referring now to FIGS.4-7, thereshown are
individual templates 52 used in connection with the copingjig 10 of the present invention. Theblank template 52 of FIG. 4 includes afirst edge 72 and asecond edge 74. Eachtemplate 52 includes a pair of mountingholes 76 on each of its ends. The mounting holes 76 are spaced such that thetemplate 52 can be flipped over and used on both thefirst end 46 and thesecond end 48 of thetemplate platform 40, as illustrated in FIG. 5. In FIG. 5, atrim pattern 78 is shown as formed on thetemplate 52 along only thefirst edge 72. FIG. 5 clearly illustrates the ability of thetemplate 52 to be flipped over and used on either end of the template platform. - FIG. 6 illustrates a second
trim pattern 78 formed in thetemplate 52. As can be understood in FIGS. 5 and 6, various types oftrim pattern 78 can be formed in the template to correspond to various types of molding. - Referring now to FIG. 7, thereshown is a template having two
different trim patterns 78 formed on opposite edge surfaces of the template. FIG. 7 illustrates that thetemplate 52 can include more than one trim pattern, which reduces the number of templates required for various types of trim work. - Referring now to FIGS.10-15, the use of the coping
jig 10 of the present invention will now be described, including the formation of a trim pattern on a blank template and the use of a created template in forming the end of a section of molding. - Initially, a trim carpenter manually forms the desired end profile on a section of decorative molding such that the finished end creates the desired appearance in the inside corner. Once this
pattern section 80 of molding has been formed with the desiredend pattern 82, the pattern section ofmolding 80 is positioned on the top surface of the molding stage, as illustrated in FIG. 10. Thepattern section 80 is positioned such that thebottom surface 81 of the molding is placed in contact with thestop rail 28. Once in position, theadjustment knob 36 is rotated, which causes theclamping block 32 to press the molding securely between the clampingblock 32 and thestop rail 28. - After the
pattern section 80 of molding is securely positioned on themolding stage 24, a blank template is secured to thetemplate platform 40 between the side rails 42. As illustrated in FIG. 10, thefirst edge 72 of theblank template 52 defines a straight edge that extends past theend pattern 82 of the pattern section ofmolding 80. Once in position, arouter 84 placed in contact with thetop plate 50 andtemplate 52, as shown in FIG. 11. As illustrated in FIG. 11, therouter 84 includes a bit having afollower 86 positioned beneath thecutting blade 88. - As illustrated in FIGS. 12 and 13, the
router 84 is operated such that thefollower 86 contacts theend pattern 82 of the pattern section ofmolding 80 such that therouter 84 can accurately follow theend pattern 82 while cutting the exact shape in theblank template 52. Since thefollower 86 and cuttingblade 88 of the router are configured as shown in FIG. 12, therouter 84 only cuts thetemplate 52, such that a trim pattern is formed along the edge surface of thetemplate 52. Once therouter 84 has finished creating the trim pattern in thetemplate 52, thetemplate 52 is ready to be used to cut an end of a section of molding. - Referring now to FIG. 14, the
template 52 having thetrim pattern 78 formed along its edge surface can be used in cutting an uncut section ofmolding 90. Initially, the uncut section ofmolding 90 is positioned on the molding stage and clamped in place by rotation of theadjustment knob 36, which causes theclamping block 32 to press themolding 90 into contact with thestop rail 28. - Once the section of
molding 90 is securely held in place, the user depresses thefirst end 46 of the template platform such that thetemplate 52 contacts themolding 90, as illustrated in FIG. 15. As previously discussed, the height of theopen channel 57 is approximately 1½″ while the thickness of themolding 90 is ¾. The difference in the thickness of the molding and the height of theopen channel 57 allows theentire template platform 40, including thetop plate 50 and thetemplate 52, to be positioned at an angle relative to the stationary and horizontal mountingstage 24. With pressure continuously applied to thetemplate platform 40, the user locks the template platform in its angled position by tightening the pair of lockingmembers 64. Once the locking members are securely tightened, therouter 84 can be used to cut the end of the unfinished section oftrim 90. - As illustrated in FIG. 15, the
router 84 includes a second bit in which thefollower 86 is positioned above thecutting blade 88. In this manner, the router bit follows thetrim pattern 78 formed on thetemplate 52 while cutting the identical pattern into the end of themolding 90. - Since the
template 52 is positioned at an angle relative to themolding stage 24 and themolding 90, the router bit creates an end pattern having a back cut angle, as illustrated by X′ in FIG. 15. The back cut angle X′ allows the front face of the molding to extend slightly further than the back face to create a more pleasing appearance to an inside corner. - In the embodiment of the invention shown in FIG. 14, the
template 52 is shown in position for cutting the left end of themolding 90. However, if it was desired to cut the right end of the molding, thetemplate 52 could be flipped over and attached near thesecond end 48 of thetemplate platform 40, as illustrated in FIG. 1. In this manner, the single template can be used to cut either end of a section of molding by simply removing the template, flipping it over, and reattaching it to the opposite end of the template platform. - As can be understood by the above disclosure, various templates can be formed for different types of trim profiles. When a different trim profile is to be cut, the template is removed and the correct template installed on the correct end of the template platform. In this manner, a simple changeover can be performed to allow for different sections of trim to be cut.
- Various alternatives and embodiments are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter regarded as the invention.
