Drywall-trimming strip for trimming archway

Abstract

A drywall-trimming strip for trimming an archway has a nose with a tabbed edge and a flanged edge. A first series of slits spaced from one another define a series of tabs spaced from one another along the tabbed edge. A flange extends from and along the flanged edge. The tabs are joined to the tabbed edge of the nose by a continuous juncture extending along and defining the tabbed edge of the nose, which has a second series of slits extending to the continuous juncture and spaced from one another, as the slits defining the tabs are spaced from one another. All parts of the drywall-trimming strip are made from a comparatively harder, less flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer Shore 82 D, except for the continuous juncture, which is made from a comparatively softer, more flexible material, such as polyvinyl chloride having a hardness of Durometer Shore 92 A.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

As illustrated in FIGS. 1, 2, and 3, a drywall-trimming strip 10 constituting a first embodiment of this invention is similar to the drywall-trimming strip disclosed in U.S. Pat. No. 6,119,420, supra, and is installed similarly to trim an archway, except as illustrated and described herein. Thus, the drywall-trimming strip 10 has a nose 12 with a tabbed edge 14 and a flanged edge 16, a first series of slits 18 spaced from one another and defining a series of tabs 20, which are spaced from one another along the tabbed edge 14, and a flange 22, which extends from and along the flanged edge 16. Also, the nose 12 has an outer surface 24 and an inner surface 26. The outer surface 26 conforms generally to an arcuate profile having a radius in a range from approximately ¼ inch to approximately ¾ inch. Also, the tabs 20 are punched so as to have multiple holes 30 and the flange 22 is punched so as to have multiple holes 32.

Further, the drywall-trimming strip 10 is co-extruded as a straight piece from a comparatively harder, less flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer 82 Shore D, and from a comparatively softer, more flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer 92 Shore A. All parts of the drywall-trimming strip 10 are made from the comparatively harder, less flexible, polymeric material, except for a continuous juncture 34, which extends along the tabbed edge 14, between the tabbed edge 14 and the slits 18 defining the tabs 20, and which is made from the comparatively softer, more flexible, polymeric material.

However, the drywall-trimming strip 10 differs from the drywall-trimming strip disclosed in U.S. Pat. No. 6,119,420, supra, because the nose 12 of the drywall-trimming strip 10 has a second series of slits 40, which extend to the continuous juncture 34 from a mid-region of the nose 12 and which are spaced from one another as the slits 18 of the first series are spaced from one another. Preferably, as illustrated, each respective slit 40 of the second series is aligned with and is separated by the continuous juncture 34 from an associated slit 18 of the first series.

As illustrated in FIGS. 4, 5, and 6, a drywall-trimming strip 100 constituting a second embodiment of this invention is similar to the drywall-trimming strip 10 and is installed similarly to trim an archway, except that the nose 112 of the drywall-trimming strip 110 differs from the nose 12 of the drywall-trimming strip 10, except that the slits 118 defining the tabs 120 of the drywall-trimming strip 110 differ (in ways that do not affect this invention) from the slits 18 defining the tabs 20 of the drywall-trimming strip 10, and except that the punched holes 130, 132, of the drywall-trimming strip 110 differ (in ways that do not affect this invention) from the punched holes 30, 32, of the drywall-trimming strip 10. Specifically, the nose 112 of the drywall-trimming strip 110 differs from the nose 12 of the drywall-trimming strip 10, because the nose 112 has a planar, outer surface 124 and a planar, inner surface 126. The nose 112 may be thus described as chamfered.

As compared to the drywall-trimming strip disclosed in U.S. Pat. No. 6,119,420, supra, and to an otherwise similar, drywall-trimming strip having a chamfered nose, the drywall-trimming strips 10, 110, tend to exhibit less distortion of the noses 12, 112, when installed to trim archways. It is necessary, however, to fill the slits 18, 118, before the drywall-trimming strips 10, 110, are painted.

Claims

1. For trimming an archway, a drywall-trimming strip having a nose with a tabbed edge and an opposite edge, the drywall-trimming strip having a first series of slits spaced from one another and defining a series of tabs spaced from one another along the tabbed edge, the tabs being joined to the tabbed edge of the nose by a continuous juncture extending along and defining the tabbed edge of the nose, the nose having a second series of slits extending to the continuous juncture and spaced from one another, as the slits defining the tabs are spaced from one another, wherein the nose of the drywall-trimming strip is made from a comparatively harder, less flexible, polymeric material, except for the continuous juncture, which is made from a comparatively softer, more flexible material.

2. The drywall-trimming strip of claim 1, wherein each respective slit of the second series is separated by the continuous juncture from an associated slit of the first series.

3. For trimming an archway, a drywall-trimming strip having a nose with a tabbed edge and a flanged edge, the drywall-trimming strip having a first series of slits spaced from one another and defining a series of tabs spaced from one another along the tabbed edge, the drywall-trimming strip having a flange extending from and along the flanged edge, the tabs being joined to the tabbed edge of the nose by a continuous juncture extending along and defining the tabbed edge of the nose, the nose having a second series of slits extending to the continuous juncture and spaced from one another, as the slits defining the tabs are spaced from one another.

4. The drywall-trimming strip of claim 3, wherein each respective slit of the second series is aligned with and is separated by the continuous juncture from an associated slit of the first series.

5. The drywall-trimming strip of claim 1, 2, 3, or 4, wherein the nose has an outer surface conforming substantially to an arcuate profile.

6. The drywall-trimming strip of claim 1, 2, 3, or 4, wherein the nose is chamfered.
