DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present device a corner trim shown generally as 110 in FIG. 1, shown as an alternate embodiment 210 in FIG. 8 and shown yet as another alternate embodiment 310 in FIG. 15.

Corner trim 110 includes vertical leg 112 having a vertical outer edge 114, a vertical internal edge 116 and a horizontal stop edge 118. Corner trim 110 further includes a horizontal leg 120 including a horizontal outer edge 122, a horizontal inner edge 124 and a vertical stop edge 126. Horizontal leg 120 and vertical leg 112 meet at inner apex 130 and outer apex 128. FIGS. 6 and 7 show corner trim 110 deployed together with vertical casing 192 and horizontal casing 190. Trim components namely corner trim 110, horizontal casing 190 and vertical casing 192 are used for example for trimming around the periphery of a door and/or window opening.

Referring now to FIGS. 8 through 14, showing alternate embodiment corner trim 210 which includes vertical leg 212 having a vertical outer edge 214, a vertical inner edge 216 and the horizontal stop edge 218. Corner trim 210 further includes a horizontal leg 220 having a horizontal outer edge 222 and a horizontal inner edge 224 and a vertical stop edge 226. Horizontal leg 220 includes a horizontal extension portion 240 having a horizontal extension inner edge 242 and a horizontal extension stop edge 244. Vertical leg 212 and horizontal leg 220 intersect at outer apex 228 and inner apex 230.

Corner trim 210 is shown deployed in FIGS. 13 and 14 together with horizontal casing 290 and vertical casing 292. The reader will note that corner trim 210 as depicted in FIG. 8, is usually used together with a mirror image of itself as shown in FIG. 14, wherein for example, deploying corner trim 210 together with horizontal casing 290 and vertical casing 292 in for example a door opening will result in the use of both a left hand corner trim 210 and a right hand corner trim 211 which is a mirror image of corner trim 210.

Referring now to FIGS. 15 through 21 showing yet another alternate embodiment, namely corner trim 310 including vertical leg 312 having a vertical outer edge 314, a vertical inner edge 316 and a horizontal stop edge 318.

Corner trim 310 further includes a horizontal leg 320 having a horizontal outer edge 322 and horizontal inner edge 324 and a vertical stop edge 326. Horizontal leg 320 further includes a horizontal extension portion 340, having a horizontal extension inner edge 342, a horizontal extension outer edge 346, and a horizontal extension stop edge 344.

Vertical leg 312 further includes a vertical extension portion 350 having a vertical extension inner edge 354, a vertical extension outer edge 356, and a vertical extension stop edge 358.

Vertical leg 312 together with vertical extension portion 350, intersect with horizontal leg 320 which includes horizontal extension portion 340 at lower inner apex 330, lower outer apex 328, upper outer apex 348 and upper inner apex 352.

FIGS. 20 and 21 show corner trim 310 deployed together with horizontal casing 390 and vertical casing 392. A mirror image of corner trim 310, namely corner trim 311 is often deployed together with corner trim 310. In other words, corner trim 310 and 311 are the left hand and right hand versions of the same corner trim 310 as described here above. A person skilled in the art will recognize that corner trim 310 together with horizontal casing 390 and vertical casing 392 is normally deployed around the periphery of door openings and window openings in the building constructions industry.

In operation, the method of the present invention may be described as follows. The method of the present invention is for forming a trim molding around a window or door opening defined by a lintel 195 and opposite jambs 197, 199. The opening has left and right upper corners 201, 203. At least two L-shaped corner trim pieces are provided such as a left-side corner trim piece 110 and a right-side corner trim piece 111. Vertical casings 192, 193 and a horizontal casing 190 are also provided. The corner trim piece 110 has a vertical leg 112 and a horizontal leg 120. The vertical leg 112 has a first mitered or sloping end surface. The horizontal leg 120 has a second mitered or sloping end surface attached to the first mitered end surface of the vertical leg 112 to form the L-shaped square corner trim piece 110. The vertical leg has a vertical outer edge 114 and a vertical inner edge 116.

The horizontal leg 120 has a horizontal outer edge 122 and a horizontal inner edge 124. The vertical leg 112 and the horizontal leg 120 have a first width (W1) and a first thickness (T1). The vertical casings 192, 193 and the horizontal casing 190 have a second width (W2) and second thickness (T2). The first width (W1) is wider than the second width (W2). The first thickness (T1) is thicker than the second thickness (T2). The vertical casings 192, 193, the horizontal casing 190, and the corner trim pieces 110, 111 define the window or door opening therebetween, as best seen FIG. 7. Preferably, the vertical inner edge 116 of the vertical leg 112 is placed about ⅛ inch outside the inner edge of the jambs 197, 199.

An outer abutment end of the vertical casing 192 is placed in direct abutment contact with an outer end 118 of the vertical leg 112. The vertical casing 192 may be shifted away from the vertical inner edge 116 and the vertical casing 192 is centered relative to the vertical leg 112. Similarly, the horizontal inner edge 124 of the horizontal leg 120 may be placed about ⅛ inch or any other suitable distance away from the inner edge of the lintel 195. Preferably, an outer abutment end of the horizontal casing 190 is placed in direct abutment contact with an outer end 126 of the horizontal leg 120. The horizontal casing 190 may be shifted away from the horizontal inner edge 124. The horizontal casing 190 may then be centered relative to the horizontal leg 120.

In another aspect of the present invention the corner trim pieces 110, 111 are provided with a first profile 205 and the vertical casing 192 and the horizontal casing 190 are provided with a second profile 207, 209, respectively, as best shown in FIGS. 6-7. The vertical casing 193 is preferably provided with a profile that is identical to the second profile 207 of the vertical casing 192. Preferably, the first profile 205 is substantially aligned with the second profiles 207, 209.

While the present invention has been described in accordance with preferred compositions and embodiments, it is to be understood that certain substitutions and alterations may be made thereto without departing from the spirit and scope of the following claims.
