Description
- This invention relates to a handrail assembly suitable for use as a safety rail or on a staircase and the like.
- Handrail assemblies for a staircase usually comprise a base rail or support, a hand rail and a set of posts called balusters or banisters which extend in between and support the handrail. Each end of the handrail may be further supported by a newel post. The handrail is supported such that it is parallel to the stairs, and the banisters are generally vertical.
- There are wide variations in the inclination of staircases, in the distance that they have to span and in the total number of bends or changes of direction required. Regulations normally confine modern, new-built staircases to within a certain range of inclinations. Older houses, which were built before the introduction of modern regulations, often have staircases whose inclination falls outside of the proscribed range. Accordingly, replacing a staircase in an older building can often require a builder to install a bespoke staircase, rather than using standard available components. Because of these factors there is a requirement to provide a handrail assembly which can accommodate wide variations of inclination and which can be assembled and installed both by the professional and by the do-it-yourself enthusiast.
- Several variable pitch stair railing assemblies have been proposed. For example, those disclosed in U.S. Pat. No. 5,056,283, U.S. Pat. No. 4,533,121 and U.S. Pat. No. 4,352,485. Further, adjustable connecting members for connecting rigid handrails or safety rails have also been disclosed in GB-A-2299370.
- It is an object of the present invention to provide a handrail assembly which allows for changes of direction and which can be used on stairways which have varying degrees of inclination and varying spans. It is a more specific aspect of the invention to provide a handrail assembly which can be readily assembled by the unskilled or at least partially skilled labour.
- Accordingly, one aspect of the invention provides a kit of parts for the assembly of a handrail installable to adopt a plurality of inclinations, the kit comprising:
- A length of rail for use as a handrail;
- Two parts of a two-part pivotable mount or connector for the rail, one part having a hollow portion into which an end of the rail is insertable, the other part being mountable on a supporting surface, the two parts being interconnectable and being mutually pivotable when interconnected.

- A length of rail for use as a handrail;
- A plurality of posts; and
- A plurality of brackets to interconnect the posts and handrail, each bracket having a surface shaped for flush engagement with a surface of the rail and a deformable portion to accommodate a plurality of inclinations of the installed handrail.
- The rail may have, in cross section, a rounded portion and a flat surface, the hollow portion of the mount preferably having an internal cross-sectional which is complimentary to that of the rail.
- The kit will preferably include a plurality of posts and a plurality of brackets attachable to the handrail, the posts and brackets may have have respective mating portions for engagement therebetween, each bracket will usually have a deformable portion to accommodate a plurality of inclinations of installed handrail. The deformable portion will preferably be able to deform to accommodate a variation in inclination of, say, 10° i.e. 5° either side of its as-formed, supplied, or equilibrium, position. In a particular embodiment, the angle of deformation is preferably 70 (3.50 either side of the as-formed position).
- The kit may further include at least one two-part pivotable mount for supporting the handrail, a first part of the mount having a hollow portion into which an end of the rail is insertable, the second part being mountable on a support surface, the two parts being interconnectable to provide pivotable motion with respect to one another.
- Also included in the kit may be one or more connectors having hollow portions into which an end of a length of rail is insertable to interconnect two lengths of rail, one or both hollow portions preferably having an internal cross section having a rounded portion and a flat portion.
- There is also provided, in a third aspect of the invention, a two-part pivotable mount or connector for a handrail, the first part of the mount having a hollow portion into which an end of a handrail is insertable, the second part of the mount being attachable to a support surface, the two parts being pivotable with respect to one another when interconnected, and wherein the internal surface of the hollow portion is shaped to prevent, in use, rotation of the hollow portion about a complimentarily shaped handrail end inserted therein.
- A yet further aspect of the invention provides a connector to connect non-parallel lengths of rail, the connector having two hollow parts into which lengths of rail are insertable, the hollow parts having openings which are non-parallel, at least one of the hollow parts has an internal surface shaped to prevent, in use, rotation of that part about the end of the length of rail when inserted therein.
- The internal surface of the hollow portion may be shaped to have a rounded part and a flat surface
- Preferably, the openings of two hollow parts are orthogonal to one another.
- In a fifth aspect of the invention there is provided a bracket to connect a post to a rail, the bracket comprising a terminal portion for engagement with an end of the post and a surface for flush engagement with a surface of the rail, and an intermediate deformable portion between the terminal portion and the surface which is deformable to accommodate different angles between the rail and post.
- A further aspect of the invention provides a method of installing a handrail assembly comprising a two-part pivotable mount or connector, a length of handrail, the assembly being capable of accommodating different inclinations of handrail, the method comprising the steps of:
- Connecting one part of the mount to a supporting surface;

Theportion 181 terminates in an integrally formedplate 182 which has apertures (not shown) extending therethrough.Apertures 185 extend through thetubular portion 181 in the region of theplanar surface 184. - FIG. 18 shows a part of a handrail assembly1 at the top of a staircase SC. The
hand rail 2 andnewel post 6 are typically formed of wood, although other material may be utilised and they both have a cross section which is in the form of a major segment of a circle, with a planar surface 2 a and 6 a respectively. - The
inclined handrail 2 is supported by aconnector 5 formed from apart 50 and apart 60, themale member 65 ofpart 60 being located within therecess 53 ofpart 50. The two parts are secured together by a nut and bolt which extends through the alignedapertures male member 65 has a curved surface which faces thecurved surface 54 of the recess to reduce friction therebetween during relative pivotal motion between the twoparts - The
part 50 is located on thenewel post 6 and secured thereto by screws which extend throughapertures post 6. Therail 2 is retained within thepart 60 by screwing through apertures present in the underside of the part and into the planar surface 2 a of therail 2. - A
bracket 4 is attached to the planar surface 2 a of thehandrail 2. Thespigot 47 of thebracket 4 is located within a hollow end of abaluster 3 so that the end of thebaluster 3 abuts theannular abutment portion 46. A screw is screwed throughaperture 43C to force the fourportions 48 outwards, away from one another to forcefully engage the inner surface of the hollow end of thebaluster 3 to prevent separation. Thebracket 4 is connected to the planar surface of the handrail by screwing screws through theapertures rail 2. - A

As will be appreciated, the provision of complimentarily-shaped internal surfaces of the connectors (10, 60 etc) and outer surfaces of thehandrails handrail 2′ may be supported against a wall by aconnector 16 or by afurther connector 10 to anewel post 6, or byconnectors - A
bracket 4′ is connected to thehandrail 2′ such that theplanar surface 41′ of thebracket 4′ lies against the planar surface 2 a′ of thehandrail 2′. Thebracket 4′ is secured to therail 2′ andbanister 3 as described above. Thebanisters 3 are secured, at their lower ends, to base rails R bybrackets - FIG. 19 shows a part of a staircase SC at the bottom of the stairs. A
newel post 6 is located within aconnector 18 which is screwed to a support S. The planar surface 6 a of the post lies against theplanar surface 184 of theconnector 18, the two being secured together by screws (not shown) extending throughapertures 185 in theconnector 18. -
Brackets 4 are secured to the base rail R and the spigots thereof are located in the hollow end ofbalusters 3, as described above. - The provision of the ‘waist’44 in the extension portion 43 of the
baluster 4 allows for the deformation of thebrackets 4 so that variable inclinations of staircase can be catered for, rather than that equivalent to the angle between thepost 3 and theplanar surface 41 of theundeformed brackets 4. The pivotal connection between the various connector parts allows for various inclinations to be accommodated. The deformable waist 43′ ofbrackets 4′ ensures that alanding handrail 2′ which is not perfectly true (i.e. horizontal) can be catered for. Indeed, the waist portion 43 of abracket 4 formed from ABS allows for a variation in incline in a staircase of about 7°, say from 380 to 45°. A similar variation in incline (i.e. 70 or 3.50 either side of the equilibrium position shown) can be accommodated by thehorizontal brackets 4′. Other materials may allow variations in inclination of up to 10°. Variations outside this limit are possible and are within the scope of the present invention. - By using
connectors handrail 2′ can be accommodated.Parts newel post 6 by screws extending throughrespective apertures 89 and 94 into thepost 6. Theparts 81 supporting thehand rail 2′. As the internal cross section ofparts newel post 6, allowing for any angle between the twohandrail 2′ parts. - If a run up the stairs is considered too long for safe support by the
balusters 3 on their own, anewel post 6 can be placed mid-run with aconnector 50″ mounted thereon. Aconnector 70 can then be used to interconnect twohandrail portions 2 to increase stability. - The
connector part 50′ will be used if ahandrail 2 requires support at a terminal end against a wall. - Typically (when using a newel post6), a handrail for a staircase SC will be installed by cutting a
newel post 6 from a length ofrail 2 and mounting it in aconnector 8. A first part of aconnector 5 will be attached to thenewel post 6. Thehandrail 2 will be cut to length and an end thereof will be inserted into the second part of theconnector 5. The support for the other end of therail 2 will be installed (either on asecond newel post 6 or against a wall or other supporting surface) and the rail located between the support and thenewel post connector 5. The pivotable nature of theconnector 5 will allow thehandrail 2 to adopt manifold inclinations.Brackets 4 will then be fitted into the ends ofposts 3 and secured therein, as previously explained. The bases of thebrackets 4 will then be screwed to the base rail R andhandrail 2 at a set distance apart. When thebrackets 4 are screwed into thehandrail 2, thedeformable waist portion 45 will deform, if necessary, to accommodate the angle of inclination between the newel post connector and other end support. - Referring now to FIGS. 20A and 20B, a third embodiment of
bracket 400 is shown formed from ABS comprising abody 440 having a flat orplanar base 441 and a hump shaped top part. The body has threeapertures apertures body 440. Thethird aperture 442C extends from theplanar base 441 at an angle and into anextension 443 which extends upwards at an angle from the curved top surface of thebody 440. - The
extension 443 has anarrow waist 444 which widens, at its' upper end to join a hollow “cup”portion 445 FIGS. 21A and 21B show anotherbracket 400′ (like features being indicated by the same numeral as in FIGS. 20A and 20B with the addition of a prime (′)) having abody 440′ with a planarlower surface 441′. Threeapertures 442A′, 442B′, 442C′ extend through thebody 440′, two of which 442A′ and 442B′ having a large diameter portion communicating with the curved upper surface of thebody 440′ and the third 442C′ having a large diameter portion communicating with the lowerplanar surface 441′ and extending into anextension 443′ having anarrow waist 444′. - The extension portion43′ terminates, at its' distal end, to join with a
hollow portion 445′. - The
brackets bodies respective extensions planar surfaces - The hollow portions are sized and dimensioned to accept the end of an
upright post 3, preferably fabricated from wood. A screw can be screwed through theapertures banister 3 to thebracket bracket deformable waist portions post 3 relative to therail - It will be appreciated that using a set of
banisters 3, somebrackets connectors deformable brackets pivotable connectors 5 enables different inclines of staircases SC to be accommodated. - Because the ends of the
handrails newel posts 6 are always hidden within connectors or connector parts, there is no need to accurately and/or precisely cut therails - The connectors and connector parts may be formed from a tough plastics material and may be moulded. They may also be formed from metal. The
handrail 2 may be formed from wood or plastics. They may be provided with a sheath, such as veneer. - The
brackets brackets spigot balusters 3 need not be round. - The
handrail 2 may have a cross-sectional shape substantially in the form of an ellipse with a minor segment removed, the internal surfaces of the connector parts and connectors having identical cross-sectional form. Other substantially curvilinear forms may be used, the only proviso being that the intended bottom surface is substantially flat and is matched by thesurface brackets - It will be further appreciated that the provision of a flat or planar surface is the easiest to manufacture. Further by providing the matched, preferably flat, surfaces on the components it will ease installation for the do-it-yourself enthusiast and for the professional handrail fitter alike. The provision of matched surfaces ensures that the components are in the correct configuration when inserted and that no rotation of the, say, connector about the end of the rail is possible.
- The components of the assembly1 may be sold as a kit bought off-the-shelf or may be ordered to complete a specific job. Clearly, the provision of the parts of the invention, together with the simple mode of construction will allow both the skilled person and the do-it-yourself enthusiast to simply and effectively install a staircase SC which is functional and attractive.
