Patented March 28, 1972 3 Sheets-Sheet 2 I Patented March 28, 1972} 3 Sheets-Sheet 5 BUILDING CORNER UNIT This invention relates generally to building siding, more particularly to comer units for use with multipanel external building siding.
Corner units are commonly used to cover the corners of wooden buildings sheathed with rectangular siding elements in the form of wood simulating shingles or clapboards. In the past, corner units have been individually attached, at the corners of a building, to opposite ends of terminal comer ends of siding courses, requiring careful, time-consuming alignment of the courses to achieve a proper weather seal and fit. Furthermore, commonly being individually fastened at both upper and lower ends to the siding, prior corner units proved difficult to align vertically and tended to buckle or malform upon weather-induced expansion and contraction of the siding elements. Also, the configurations of the prior corner units were structurally ill-suited to be formed by molding of organic plastic, (e.g., being commonly provided with reverse bent bottom tabs requiring an undercut).
Accordingly, it is a major object of this invention to provide an improved novel weather-protective corner unit for use with panels of exterior siding constructed to be independently and easily attached to wooden inner sheathing without buckling or popping, being easily aligned horizontally with adjacent courses to be jointed at the corner, and readily aligned vertically by telescopically engaging interlocking means, all for overlappingly and sealably holding the siding terminal ends in fixed relation to the underlying wooden sheathing.
A further object of the invention is to provide a corner unit for artificial siding having a wood-simulating exterior surface integrated with the siding, preferably consisting of molded organic plastic materials such as the vinyls though, alternatively, formed sheet metal may be employed for the corner units of the invention.
These and other objects of the invention are accomplished by providing angular corner units at the corners of a building for overlapping terminal ends of siding elements, each corner unit having a pair of wings at approximately right angles to each other with the wings tapering outwardly and downwardly from the top end to a horizontal angular shelf extending inwardly at the bottoms of the wings for cooperation with the tops of the wings of a subjacent like corner unit. Also, each corner unit has a bracket inwardly offset from the top ends of the wings of the corner unit for nailing said unit to opposing housing sheathing at the comers thereof, plus a prong preferably extending downwardly from said shelf for vertically, telescopically engaging a subjacent like corner unit effective to connect any two corner units in vertical alignment, with the shelf of an upper corner element held in fixed horizontal relationship with the top end of a subjacent like corner element. In preferred embodiments and uses of the invention, the corner elements are of like exterior finish and color as the artificial siding unit they overlap and thus cover the ends thereof. Being mounted directly at the corner portion of the housing sheathing, the corner elements may be attached thereto either before, as is normal, or even after the application of the siding. The comer units thus facilitate assembly of the siding, as desired. When attached before the siding elements, the shelf portion of the comer element can serve as an aid in horizontally aligning a given course of panels extending left and right from the comer unit.
As above indicated, the invention may employ an angular corner unit constructed of metal in essentially the same form, preferably with a surface to match that of the siding elements employed therewith.
For the purpose of more fully explaining the objects and features of the invention, reference is now made to the following description of preferred embodiments of the invention, together with the accompanying drawings, wherein:
FIG. 1 is a view of a corner portion of a completed wall structure showing a vertical series of interlocking corner units overlapping terminal ends of a course of siding elements at an exterior corner of a building;
FIG. 2 is a sectional view taken along line 2-2 of FIG. 1;
FIG. 3 is a view of two adjacent comer units in vertical interlocking engagement, with mid-portions of the wings of each unit broken away;
FIG. 4 is a sectional view of a modified embodiment consisting of a single, wide-width clapboard comer element;
FIG. 5 is a sectional view of still another clapboard embodiment of a comer element for two-narrower course-simulating wooden clapboard siding;
FIG. 6 is a view illustrating modified comer units in telescopic interlocking engagement with mid-portions of the wings broken away, in which the modification involves a reversal of the position of the interlocking prong from the bottom of the corner unit (as shown in foregoing figures of the drawings) to to top of the modified corner unit;
FIG. 7 shows in plan a partially completed modified corner unit that readily can be made from sheet metal or other sheet materials by stamping and forming operations; and
FIG. 7a shows the partially completed corner unit of FIG. 7 in its completed right-angular conformation ready for use.
Referring to the drawings, a corner unit 20 (FIGS. 1, 2 and 3) represents a preferred embodiment with an integral woodsimulating surface molded from vinyl plastic, having an exterior surface pattern of wood grain cedar shake shingles (as, for example, in the siding elements of Ser. No. 795,509, filed Jan. 31, 1969 now U.S. Pat. No. 3,593,479 of July 20, I971, assigned to the assignee of this application). FIG. 3 shows the comer unit 20 of FIGS. 1 and 2 as connected with an identical corner unit 20 therebelow in vertical alignment therewith for overlappingly joining terminal ends of generally rectangular, interlocking, like rectangular elements or panels 25 or 26 of matching exterior finish. The corner units 20 is advantageously constructed to interlock with a like subjacent unit 20 to form a continuously connected weatherproof vertical series of comer units. Interlocking is accomplished by the novel telescopic cooperation of prong 31 of unit 20 with the bracket 30 of unit 20, as hereinafter described.
As best seen in FIG. 3, a view taken from the inside, corner units 20 include two sidewise extending wings 22 and 23, perpendicularly intersecting along comer line 24, with the wings extending widthwise a substantial distance to overlap (for weather protection) the terminal ends of like siding panels 25 and 26, the wings having outwardly and downwardly tapering edges 27 and 28. Also included in each corner unit as seen in FIG. 3, a view taken from the inside, is a horizontal angular bottom shelf 29, a top-mounted nailing bracket shown generally at 30, and a bottom-mounted prong 31 projecting downwardly from the inner portion of the shelf 29. The top edges 32 and,33 of wings 23 and 22 are horizontally aligned for abutting the lower surface of an adjacent shelf 29 of an overlying unit, as shown in FIG. 3. The nailing bracket 30, preferably formed integrally at the top of wings 22 and 23, includes an inwardly offset support member 36 extending horizontally inwardly from adjacent top portions of wings 22 and 23 with mounting surface 37 in the same plane as the tops 32 and 33. Also included in bracket 30 are two spaced vertical walls 40 and 41 attached to opposite sides of support members 36, horizontal legs 42 and 43 extending inwardly from the respective upper edges of said walls to an angularly formed member 44 having vertically extending perpendicular walls provided with nail holes as shown for nails (see FIGS. 4 and 5) anchoring the comer element to the corner portion of the housing sheathing 45. Legs 42 and 43 are disposed in a plane parallel with and vertically spaced from the support member 36, and bracket 30 includes an opening 46 providing a socket of generally square shape as viewed from above in cross section (see FIG. 2), with edges 47 and 48 for receiving prong 3!, downwardly extending from the overlying unit as shown.
Being formed with shelf 29, prong 31 projects downwardly from the inner comer of said shelf with portions 50 and 51 disposed at right angles joined at corner 53 parallel with channel 44 and offset from wings 22 and 23 by shelf 29 for engaging said opening 46 (see especially FIG. 3), the prong guide portions 50 and 51 being provided for easy entry into the opening 46.
As seen in FIG. 4, corner unit 20a, of different surface conformation, is independently attached to the sheathing 45 by driving nails 60 and 61 through the holes provided in bracket 30 directly into the corner portion of the sheathing with shelf 29a in horizontal alignment with a given course of siding 26a already in place, for example. With a lower comer unit 20a thus secured, a second corner unit 20a (see FIGS. 3 and 4) may then be mounted above the lower unit 20a by first inserting prong 31 downwardly into opening 46 such that the bottom of shelf 29a surmounts support member 36 and top edges 32 and 33 (see FIG. 3) and the inner edges of shelf 29a engage walls 40 and 41 wedging the prong portions 50 and 51 into the opening 46 of the lower unit 20a, thereby telescopically connecting the comer upper unit 20a with the lower corner unit 200. By this construction, the upper corner unit 20a is prevented from moving downwardly or laterally and is aligned vertically with respect to a lower corner element 20a and the comer of the wooden sheathing 45. Also, such assembly positions shelf 29a adjacent tops 32 and 33 of the lower comer unit 20a in horizontal alignment therewith. Thereafter, the upper corner unit 20a is attached directly to the Sheathing by nailing its respective bracket 30 in place.
Alternatively, a comer unit to be installed may be fitted over one previously attached siding panel in horizontal alignment therewith, say a left one, said panel being previously attached to intersecting walls 67 and 68 of sheathing 45 (see FIGS. 1 and 2) with wings 22 and 23 overlying the terminal portions of panels 25 right and 26 left, and then a right comer panel of the same course of siding may be applied to one wall using such corner element for starting said right panel of the same course. Also, corner units may be installed prior to either of the left and right panels of the same course being attached to the sheathing.
In another embodiment of the invention of different surface conformation (FIG. the wing members 56 and 57 of comer unit 20b are formed to overlie terminal ends of adjacent unitary double course clapboard siding panels 25b and 26b.
In yet another embodiment of the invention shown in FIG. 6, prong 31a is reversed to a top mounted position on modified corner unit 20c, projecting upwardly with corner 53a aligned with comer line 24. Shelf 29b, having inwardly offset bearing surfaces 70 and 72 is provided with angular slot 74 ofiset inwardly from corner line 24. The upper corner unit 20c, as viewed from the outside in FIG. 6, is telescopically connected to the lower unit by inserting prong 31a upwardly into slot 74 with walls 40 and 41 of bracket 30 being wedged against bearing surfaces 70 and 72 and shelf 29b surmounting top edges 32 and 33 of the subjacent like corner unit 20c.
In still a further embodiment of the invention, a corner cap 80, stamped from flat sheet metal stock as seen in FIG. 7, having two laterally extending wings 22a and 23a joined along corner line 24a, each wing before forming including an upwardly extending tab 81 and a downwardly extending shelf member 82 having a prong member 84 and slanted edge 85, is readily formed by bending into a corner cap of right angular conformation for covering terminal ends of siding as seen in FIG. 7a.
As seen in FIG. 7a the respective shelf members 82 are formed horizontally inward being joined along centrally abutting edges 85 with respective adjacent prong members 84 bent downwardly perpendicularly thereto and joined to provide a unitary prong of right angular conformation. Also respective tab members 81 are formed by bending to provide horizontal inwardly projecting portions 86 and perpendicular vertically extending portions 88. A corner cap to be installed is fitted over a previously attached subjacent like comer cap 80 with respective shelf members 82 resting on respective horizontal portions 86 of said subjacent comer cap and respective vertical portions 88 of tabs 81 extending beneath the inner portions of Wings 220 and 23a of said subjacent corner cap 80 immediately adjacent comer line 240.
