1. Field of Invention
This invention pertains generally to tools for use in the installation of cabinets and, more particularly, to apparatus and a method for scribing a trim strip to fit between a cabinet and a nearby wall or ceiling.
2. Related Art
When installing frameless cabinets, spaces are left between the cabinets and nearby walls and/or ceilings to allow for variations in the surfaces of the walls or ceilings. After the cabinets have been installed, the spaces are filled with trim strips, commonly known as scribe strips, which have been trimmed or cut to conform to the contours of the surfaces of the walls and/or ceilings.
The fitting of a scribe strip was traditionally done by transferring the contour of the wall or ceiling to the scribe strip with a carpenter's scribe or other marking tool and then cutting the scribe strip to mate with that contour with a tool such as a saw or a plane or, more recently, with a router.
U.S. Pat. No. 5,013,196 discloses a scribing accessory for an offset router which has a guide wheel disposed concentrically of the router bit for engagement with a surface to facilitate the trimming of a laminate or other material to mate with the surface. This tool is marketed under the trademark Quickscribe.
It is in general an object of the invention to provide a new and improved holding tool and method for scribing a trim strip to fit between a cabinet and a nearby wall or ceiling.
Another object of the invention is to provide a holding tool and method of the above character which overcome the limitations and disadvantages of techniques heretofore employed in the installation of scribe strips.
These and other objects are achieved in accordance with the invention by providing apparatus and a method for scribing a trim strip to fit between a cabinet and a nearby surface with a first edge of the trim strip facing one side of the cabinet and a second edge of the trim strip facing the surface in which a guide is run along the surface, a scribing tool spaced a predetermined distance from the guide transfers the contour of the surface to the trim strip as the guide is run along the surface, and the trim strip is held in a fixed position with the first edge of the trim strip offset from the side of the cabinet by the predetermined distance as the contour of the surface is transferred to the trim strip.
As illustrated in
The holder has a first pair of jaws in the form of flanges 26, 27 between which the outer wall 12 of the cabinet is received and a second pair of jaws in the form of flanges 28, 29 between which rib 21 on the back side of trim strip 11 is received. Thumbscrews 30, 31 are threadedly mounted in flanges 26, 28 and provide means for securing the holder to the cabinet wall and the trim strip to the holder so that the trim strip is held firmly in a fixed position relative to the cabinet wall while it is being scribed or trimmed. Except for the thumbscrews, each of the holders is formed as a one-piece, rigid body having contours which mate with the cabinet wall and the trim strip.
The spacing between the flanges 26, 27 is slightly greater than the thickness of the thickest cabinet wall with which the holder will be used. Thus, for example, in the United States where cabinet walls typically have a thickness on the order of ¾, ⅝ or ½ inch, the spacing between the flanges can be on the order of 13/16 inch. The spacing between flanges 28, 29 is slightly greater than the thickness or width of the rib on the trim strip so the sides of the rib fit closely with the faces of the flanges.
The inner faces 32, 33 of flanges 27, 28 serve as reference surfaces which align the trim strip so that the inner edge 34 of the trim strip which will face the cabinet is offset inwardly or laterally from the outer surface 35 of the cabinet by a predetermined distance d which corresponds to the distance between a guide and a marker or cutter in the tool used for scribing or trimming the trim strip. In that regard, it will be noted that thumbscrew 30 presses the outer surface of the cabinet wall tightly against the face 32 of flange 27 to provide an accurate reference regardless of the thickness of the cabinet wall.
In the embodiment illustrated in
Operation and use of the embodiment of
With the trim strip thus clamped in position, the outer edge of it is trimmed to match the contour of the wall or ceiling by running the router along the strip with guide wheel 36 in engagement with the wall and router bit 37 cutting the strip. Since the inner edge 34 of the strip is offset inwardly from the outer surface 35 of the cabinet wall by the same distance d as the distance between the periphery of the guide wheel and the cutting edge of the router bit, the strip is cut to have the same width as the space between the surfaces of the cabinet and the wall or ceiling.
After the strip is trimmed, it is removed from the clamps, the clamps are removed from the cabinet, and the strip is pressed into position in the space between the cabinet and the wall or ceiling, with the tongue 16 on cleat 17 being received in the groove 18 on the back side of the strip. In most applications, the frictional engagement between the tongue and groove will hold the trim strip in place, but it can also be glued in place, if desired.

Operation and use of the embodiments of
The invention has a number of important features and advantages. It is easy to use, and provides a fast and accurate way to scribe trim strips to fit between cabinets and the surfaces of nearby walls and ceilings.
It is apparent from the foregoing that a new and improved holding tool and method for scribing a trim strip to fit between a cabinet and a nearby wall or ceiling have been provided. While only certain presently preferred embodiments have been described in detail, as will be apparent to those familiar with the art, certain changes and modifications can be made without departing from the scope of the invention as defined by the following claims.
