Description
- This is a continuation-in-part of U.S. application Ser. No. 10/688,467, filed Oct. 17, 2003, which is incorporated herein by reference.
- The invention relates generally to the assembly of a flight of stairs, and, more particularly, to a bracket suitable for such assembly.
- Typically, the construction of a flight of stairs has throughout the years involved cutting a pair of stair risers out of elongated pieces of lumber with right angular notches being cut into each piece at appropriate spacings before positioning and nailing down stair treads.
- The building of staircases is time-consuming and the cutting of lumber requires great skill, care and craftsmanship. This cutting is often on a custom basis and is usually done offsite. This is all time consuming and is often the cause of delays in the course of construction projects.
- Furthermore, flights of stairs constructed out of wood have been known to deteriorate, especially when used outdoors.
- In light of the above, there is a need for a system and method for constructing flights of stairs easily on site avoiding the need for custom ordering offsite. There exists also a need for making the construction of staircases, or any similar type of construction, easy and convenient for the everyday handyman.
- This and other objects of the invention are achieved by a stairway that has a pair of stringers and at least one stair assembly disposed in spanning relationship across the stringers. The stringers are mounted in inclined, spaced-apart, parallel relationship. Each stringer has a top surface and a side surface. Each stair assembly has a pair of brackets and a tread, with the tread having one of the brackets affixed to each end thereof. Each bracket is affixed along a length of each of the stringers.
- Each of the brackets has a first and a second face in intersecting angular relationship, with a flange disposed perpendicularly from a side of the first face. The first face and the flange of each bracket are mounted in abutting relationship on the respective top and side surface of the stringer.
- In some embodiments, the bracket has a further flange disposed in parallel relationship on the opposite side of the first face. In such an embodiment, the first face and the flanges are sized and adapted for abutting relationship on the respective top and both side surfaces of the stringer.
- In the embodiments, the first and second bracket faces intersect at a back end of the bracket, with a supportive web disposed between the first and second faces along the length of each face.
- In some embodiments, the web terminates at a front end of the bracket in an arcuate front face. In other embodiments, the web terminates at a front end of the bracket in a front face that is provided with a pair of pair of mutually perpendicular surfaces for affixing a riser strip or light strip thereto.
- In the embodiments, an aperture is provided in each flange for passage therethrough of a fastener affixing the bracket to the stringer, and an aperture is provided in each second face for passage therethrough of a fastener affixing the bracket to the tread. In some of the embodiments, an aperture is provided in each bracket for passage therethrough of a fastener affixing the bracket to a railing system component.
- In many embodiments, the bracket comprises a thermoplastic material, especially a reinforced thermoplastic.
- The angle of incline of the stringers and the angle between the first and second faces are substantially identical.
- In many embodiments, each bracket of each pair of bracket is a mirror image of the other bracket, with respect to the placement of the flange on the first face. In some of these embodiments, each bracket of each pair is provided with corresponding mating means such that a pair of mirror image brackets can be accurately aligned in a ganged fashion.
- The invention will be better understood through reference to the exemplary embodiments disclosed herein, wherein identical parts are identified by identical part numbers, and wherein:
-
FIG. 1 is a front perspective view of a first exemplary embodiment of a bracket; -
FIG. 2 is a side elevation view of theFIG. 1 bracket and the structural member to be connected thereto; -
FIG. 3 is a front perspective view of a pair of a second exemplary embodiment of the bracket; -
FIG. 4 is a side elevation view of one of theFIG. 3 brackets; -
FIG. 5 is a top plan view of one of theFIG. 3 brackets; and -
FIG. 6 is a side perspective view of a flight of stairs, constructed using the bracket ofFIG. 3 . - Referring first to
FIGS. 1 and 2 , a first exemplary embodiment of abracket 10 intended for use in constructing a flight of stairs is illustrated. Thebracket 10 has afirst face 12 and asecond face 14, the faces being in angular intersecting relationship, so the first and second faces meet at a back end 16. At a front end 18, first and second faces are connected by a front face 20, which is shown in this embodiment as an arcuate member. In addition to arcuate front face 20, there may be additional support provided between the first andsecond faces Bracket 10 may be provided in mirror-image pairs, the two brackets in a pair being distinguishable by the placement of at least one flange 24 that extends belowfirst face 12 on one side of the bracket. As is clearly noted, each flange 24 is disposed perpendicular tofirst face 12 and the flange is provided with anaperture 26. Thebracket 10 is also provided with an indexing window 28 along a flange 24, the indexing window being useful for aligning the bracket accurately to a pre-measured mark on a stringer during installation. As best seen inFIG. 1 , thesecond face 14 is provided with at least two apertures 30. In this embodiment, apertures 30 are disposed normal tosecond face 14. -
FIG. 2 also shows two treads 210, as they would be positioned atopbracket 10, in the manner described below. - A second
exemplary embodiment bracket 110 is seen inFIGS. 3 through 5 .FIG. 3 shows a front perspective view of a pair of thesecond embodiment brackets 110 in a manner that illustrates the mirror-image configuration, as was noted regardingbracket 10. Eachbracket 110 has afirst face 12 and asecond face 14, the faces being in angular intersecting relationship, so the first and second faces meet at a back end 16. At a front end 18, first and second faces are connected by afront face 120. Unlike front face 20 ofbracket 10,front face 120 is not smoothly arcuate. Instead, thefront face 120 has a pair of mutually perpendicular surfaces 32, 34, that facilitate the installation of a riser strip or light strip. Of these surfaces, surface 32 is parallel tosecond face 14. As inbracket 10,bracket 110 has additional support provided between the first andsecond faces web 122, which is generally the same as web 22 ofbracket 10, but is shown inFIGS. 3 and 4 as having an optional additional boss 36, which is provided with anaperture 38. - As with
bracket 10,bracket 110 is provided with at least oneflange 124 that extends belowfirst face 12 on one side of the bracket.Flange 124 is disposed perpendicular tofirst face 12 and the flange is provided with at least oneaperture 26. One of the apertures, designated 26 a, has a slotted profile, instead of the circular profile illustrated in theother apertures 26. This feature provides for minor adjustment of the bracket height and can compensate for warpage, size variations, etc. in the other materials. Bracket 110 is also provided with indexing window 28 alongflange 124, the indexing window being useful for aligning the bracket accurately to a pre-measured point on a stringer during installation. - As best seen in
FIG. 5 ,second face 14 is provided with at least two apertures 130. Unlike apertures 30, apertures 130 are shown in an oblique angle relative tosecond face 14, which allows angled installation on mounting screws to secure a tread atop the second face. An optional feature, shown inFIG. 5 , but not illustrated inFIG. 1 , is atread centerline marker 40. -
FIG. 4 also shows component of a railing system, namely, a baluster 220, which may be affixed to thebracket 110, especially throughaperture 38. - It will be clear to those of skill in this art that either embodiment of
bracket bracket -
FIG. 6 provides a side elevational view of an exemplary flight ofstairs 200 constructed using pairs ofbrackets 110. It is evident fromFIG. 6 that each of thebrackets 110 shown will be paired with a mirror-image partner that is not seen inFIG. 6 . The mirror-image pairs ofbrackets 110 are attached in a secure manner to a pair of parallel stringers 202 that have been positioned and secured in the angled manner shown inFIG. 6 before the brackets are installed. While stringers 202 will typically be wood, other materials of construction will be a design choice of one of ordinary skill. Each stringer 202 has a planar top surface 204 and a pair of opposing side surfaces 206. - Stringers 202 are installed so that a longitudinal centerline is inclined at an angle to the horizontal. This angle, also referred to as the “pitch” of the stringer, will be equivalent to the angle between the first and second faces 12, 14 of the
bracket brackets - Locating
individual brackets - After marking off the intended position of all of the bracket pairs, or at least after marking off the position of a first pair of the
brackets 110, the first pair will be attached to the respective stringers 202. In a preferred placement, abracket 110 will be placed on a stringer 202 with thefirst face 12 of the bracket seated atop the angled top surface 204 and theflange 124 is flush against a side surface 206, with bracket back end 16 also contacting top surface 204. Eachaperture 26 onflange 124 provides a fastening site for joining thebracket 110 to stringer 202. As noted above, the exact structure and size offlange 124, including the number ofapertures 26 is a matter of design choice. While the illustratedbrackets flange 24, 124 provided on only one side thereof, a bracket having flanges on both sides to provide an “inverted-U” shaped channel may be appropriate and useful. In such an instance, the channel, comprising thefirst face 12 and theflanges 24, 124 would straddle top surface 204 and the bracket pairs will be identical rather than mirror images. - In an exemplary assembly embodiment, the bracket pairs will all be installed, forming a stairway framework, before the treads 210 are installed. With each pair of
brackets 110 in place, the second faces 14 on thebracket pair 110 are ready for installation of treads 210. Thesesecond surfaces 14 provide parallel, aligned planar surfaces horizontal to the floor, so one or more treads 210 spanning the gap between the surfaces may be affixed. The apertures 30 or 130 provide a fastening site through which any suitable fastener may be passed into the underside of the tread 210 lying directly atopsecond surface 14. Screws are typically preferred. - Also shown attached to
brackets 110 are a number of riser strips 212. - In other embodiments, individual steps, including the
brackets 24, 124 and the tread 210, will be fully assembled before the next set of brackets will be placed on stringers 202. -
FIG. 6 also shows at least a partial railing system that may be attached to the flight of stairs as assembled using the inventive elements. The railing system, which is preferably completed after all steps are affixed, comprises newel posts (a bottom newel post 214 shown), a plurality of balusters 220, placed intermediate the newel posts, and a handrail (not shown). The newel posts 214 are distinguished from the balusters in that they typically are larger than the balusters, are positioned at the ends of the stairs, and effectively anchor the handrail independent of the stringers 202. The balusters 220 may be attached to the stringers 202, thebrackets 110, or both. InFIG. 6 , a number of balusters 220 are shown to provide environment for their placement in a typical application. As would be expected, the handrail, if shown, would be inclined in a manner parallel to stringers 202. - There may be a need to accurately align a pair of side by
side brackets FIGS. 3 through 6 asprojections 42 and correspondingly opposite matching recesses 44 allows for this option. These mating means are arranged to disposeflanges 124 on the respective first faces 12 in opposing parallel relationship on the outside of the combined pair rather than in abutting relationship internal to the first face. - Other embodiments and uses of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. The specification and examples should be considered exemplary only and do not limit the intended scope of the invention.
