- This disclosure relates to a rail that can be easily installed adjacent to a variety of staircases. Toddlers who are learning to ascend and descend stairs may be able to use such handrails to safely learn to do so. The handrails described herein are designed to facilitate balance. Toddlers and children can use the handrail for guiding and stabilizing themselves to improve the safety of passage on the staircase. The handrails may enhance balance, which may lead to decreased falls and fear of falling. In addition, a child who uses a handrail for every step will often be more secure traversing a set of stairs.
- In some applications, it may be beneficial to have a temporary, detachable handrail which has easily adjustable supports and members that allow the handrail to be fitted to various staircases. A temporary rail can be advantageous because it assists the user and can easily be removed and disassembled when the child no longer uses it. Alternatively, as the child grows, the handrail assembly can be detached and re-attached at a greater height above the steps, to accommodate the child's height.

FIG. 1A illustrates a front view of adetachable handrail assembly 100 in the form of a support cylinder. Thehandrail assembly 100 can be attached to thewall 102, below thepermanent handrail 104, at a height suitable for a child learning to climb thestairs 101. - In some embodiments, the
handrail assembly 100 comprises at least one length oftubing 110. Thetubing 110 can be constructed of any appropriate material, such as, for example, plastic. Thehandrail assembly 100 may comprise a strong but lightweight flexibleplastic tubing 110 that will not decrease in strength after months of repeated use and can endure substantial weight. Thetubing 110 can have any appropriate cross-sectional profile, such as, for example, circular, square, or any other profile. - For example, the
tubing 110 can be pipe comprising polyvinyl chloride (PVC) polyamide, polyurethane, polyethylene, polypropylene, acrylonitryl-butadiene-styrene (ABS), polycarbonate, chloronated polyvinyl chloride (CPVC), an acrylic polymer and alumina trihydrate material sold as CORIAN® by the Dupont Corporation of Wilmington, Del., or the like, or combinations of two or more of these materials. Thehandrail assembly 100 can include a single length oftubing 110, or a plurality of lengths oftubing 110 joined end-to-end with each other. - The
handrail assembly 100 can be secured to awall 102 withexternal supports 150. Eachsupport 150 has a flat plate orflange 152 for mounting thesupport 150 to thewall 102. In some embodiments, thesupports 150 comprise heavy duty plastic, such as PVC, polyurethane, polyethylene, ABS, polycarbonate or the like. In other embodiments, thesupports 150 comprise a metallic material, such as aluminum, steel, stainless steel, or any other appropriate material. - In some embodiments, as shown in
FIG. 3 , an adhesive 160—such as a pressure sensitive adhesive—is used to detachably secure thesupports 150 to thewall 102. The pressuresensitive adhesive 160 can include an elastomer compounded with a suitable tackifier (e.g., a rosin ester). The elastomers can be based on acrylics, bio-based acrylate, butyl rubber, ethylene-vinyl acetate (EVA) with high vinyl acetate content; natural rubber, nitriles, or silicone rubbers. The adhesive can include styrene block copolymers (SBC), resins associating with endblocks (cumarone-indene, α-methyl styrene, vinyl toluene, aromatic hydrocarbons, etc.), resins associating to the midblocks (aliphatic olefins, rosin esters, polyterpenes, terpene phenolics), styrene-butadiene-styrene (SBS), styrene-ethylene/butylene-styrene (SEBS), styrene-ethylene/propylene (SEP), styrene-isoprene-styrene (SIS), vinyl ethers, or combinations thereof. In some embodiments, thesupports 150 of thehandrail assembly 100 can be attached to thewall 102 using the adhesive 160, without screws or nails, so that thehandrail assembly 100 can be detached and/or moved one or more times without damaging thewall 102. - As shown in
FIGS. 4 and 5 , in other embodiments, thesupports 150 can be attached to thewall 102 using fasteners, such as screws (not shown). Thesupports 150 may includeapertures 164 through theflanges 152 to receive the fasteners. When mounting thehandrail assembly 100 to thewall 102, the installer may insert the fasteners through theapertures 164 and into thewall 102 to secure thehandrail assembly 100 to thewall 102. In some embodiments, thesupports 150 are spaced along thetubing 110 such that the fasteners may be inserted into studs in thewall 102 to provide a more secure engagement. In other embodiments, drywall anchors may be used to retain the fasteners in thewall 102. - The
supports 150 have asecond flange 154 for attaching thetubing 110 to thesupports 150. In some embodiments, thesecond flanges 154 are joined to thetubing 110 using fasteners 156 (e.g., screws) (shown inFIG. 3 ). Thefasteners 156 may permanently join thesecond flanges 154 to thetubing 110. Alternatively, thefasteners 156 may removably join thesecond flanges 154 to thetubing 110. Thefasteners 156 may be inserted upward through thesupports 150 such that the threaded portion of thefasteners 156 engage thetubing 110. Alternatively, the fasteners may be inserted downward through thetubing 110 such that the threaded portions of thefasteners 156 engage threaded holes in the supports 150 (e.g., holes 157 shown inFIG. 5 ). Alternatively, or additionally, thesecond flanges 154 may be joined to thetubing 110 using a plastic welding adhesive, epoxy, or glue. In some embodiments, each section oftubing 110 has a respective set ofsupports 150. Therefore, thesupports 150 may be permanently attached totubing 110 while still allowing sections oftubing 110 to be coupled and decoupled. - The elongated sections of
tubing 110 have a suitable thickness and strength to prevent bending or breakage. For example, the wall thickness of the sections 301, 302 can be in a range from 0.09 inch (2.4 mm) to 0.25 inch (6.4 mm). The sections oftubing 110 may also be any appropriate length. - In some embodiments, as shown in
FIG. 1B , ahandrail assembly 200 comprises a plurality of sections oftubing 110. For example, thehandrail assembly 200 can include two, three or more sections oftubing 110. For example, as shown inFIG. 1B , each section oftubing 110 in thehandrail assembly 200 can have amale connector 130 at one end and afemale connector 145 at the opposite end, permitting any desired number of sections oftubing 110 to be assembled without using any tools. One embodiment of themale connector 130 is shown in detail inFIGS. 6A-6D and is described below. One embodiment of thefemale connector 145 is shown inFIGS. 7A-7D and is described below. In some embodiments, theconnectors tubing 110. In other embodiments (not shown), the sections oftubing 110 can be joined using threaded or unthreaded sleeves. In some examples, the sections oftubing 110 havemale connectors 130 at each end, and a sleeve having apertures at each end configured to receive portions of the male connectors to join two sections together. In other examples, the sections oftubing 110 are joined by a sleeve with glue, plastic cement, or a resin system. In other embodiments (not shown), the sections oftubing 110 can be joined by bayonet fittings, compression fittings, or the like. -
FIG. 2 is an isometric view of a handrail assembly having a single section.FIG. 3 is an exploded view of thehandrail assembly 100 ofFIG. 2 . Thetubing 110 is encased in adeformable foam sleeve 120. Thefoam sleeve 120 can be a closed cell polymeric foam, such as a low-resilience polyurethane foam (LRPu) (“viscoelastic” polyurethane foam) that matches pressure against it, yet slowly springs back to its original shape, also referred to as memory foam. In other embodiments, thesleeve 120 comprises expanded polystyrene (EPS), extruded polystyrene (XPS), polystyrene copolymers (including styrene plus one or more other monomers), or expanded polystyrene composites containing cellulose or starch. In other embodiments, thesleeve 120 comprises polyolefin foam. Alternatively, thesleeve 120 can comprise a closed cell sponge rubber and plastic foam such as DURAFOAM™ foam sold by Monmouth Rubber & Plastics Corp. of Longbranch, N.J. In other embodiments, thesleeve 120 can comprise a non-woven felt material. - In various embodiments, a
sleeve 120 comprising any of the above materials can be coated with an anti-microbial coating. Afoam sleeve 120 with antimicrobial coating acts as a protective covering that provides a comfortable and firm grip for the child. The antimicrobial coating on thesleeve 120 can also prevent the spreading of germs and inhibits microorganisms from growing. For example, in some embodiments, thesleeve 120 comprises antimicrobial coated DURAFOAM™ closed cell sponge rubber and plastic foam. The result is a comfortable, easy-to-grip, non-slip, moisture-resistant sleeve 120, which is easy to clean. - The
sleeve 120 can include one or more sleeve sections. In some embodiments (not shown), thesleeve 120 is a single piece having a continuous circumference. In other embodiments (not shown), thesleeve 120 can comprise a plurality of sleeve sections, where each sleeve section is shorter than thecomplete handrail assembly 100. These shorter sleeve sections may be easier to slide longitudinally over thetubing 110 ofhandrail 100, because of smaller contact area per sleeve section. In some embodiments, as shown inFIG. 4 , eachsleeve 120 may extend to the end of each section oftubing 110 and cover theconnectors components adjacent sleeves 120 may abut one another such that there are not gaps between thesleeves 120. In some embodiments, a socket, fitting covering, or tape may be placed over the abutting ends of (or gap between) two adjacent sleeve sections, for protection. - In other embodiments, as shown in
FIGS. 2 and 3 , thesleeve 120 can have alongitudinal slit 126 extending from the inner diameter of thesleeve 120 through the wall of thesleeve 120 to the outer diameter of thesleeve 120, and running the entire length of thesleeve 120. Thesleeve 120 having aslit 126 can easily be wrapped or pushed over the side wall of thetubing 110. In some embodiments, eachend 124 of thesleeve 120 has a respective support-receivingslot 122 for receiving the arm of thesupport 150. The support-receivingslots 122 allow thesleeve 120 to be installed around thetubing section 110 while the handrail assembly is already installed on thewall 102. In some embodiments, thesleeve 120 is secured to thetubing 110 using glue or other adhesives. This may prevent thesleeve 120 from moving relative to thetubing 110 during use, which may increase the safety of thehandrail 100. In such embodiments, thesleeve 120 may be glued or adhered to thetubing 110 during manufacturing or, alternatively, by the user at the time of assembly and installation. In some such embodiments, an adhesive and backing paper is applied to thetubing 110 or thesleeve 120 during manufacturing and the user removes the backing paper and affixes thesleeve 120 to thetubing 110 during assembly and installation. - As shown in

- Operation
- In various embodiments, the user assembles the
handrail assembly 100 prior to mounting thehandrail assembly 100 to the wall. In embodiments in which more than one section of tubing is desired, the user joins two ormore tubing sections 110 by inserting themale projection 130 c ofmale connector 130 into theaperture 145 c of thefemale connector 145, for example. Thecap 135 may then be placed over the exposedmale connector 130, and theplug 140 is placed in the openfemale connector 145. Thefoam sleeve 120 is placed over thetubing 110. The sections offoam 120 can slide longitudinally over thetubing 110, or thefoam sleeve 120 is slit longitudinally (with a longitudinal slit 126) and is wrapped around thetubing 120. Thetubing 110 is then attached to thesupports 150. - The
handrail assembly 100 is then attached to thewall 102 above thestairs 101. In embodiments having adhesive 160, release paper (not shown) may be removed from the pressuresensitive adhesive 160. Theflanges 152 may then be pressed against thewall 102 to couple thehandrail assembly 100 to thewall 102. In embodiments, such as shown inFIGS. 4 and 5 , in which fasteners are used to mount thehandrail assembly 100 to thewall 102, the fasteners are inserted through theholes 164 in thesupports 150 and inserted into thewall 102. - In some embodiments, the length of the
tubing 110 is selected to extend beyond the top and bottom steps, and is attached at either end to a support fixture (which can be one of thesupports 150, for example) using a pressure-sensitive adhesive or fasteners to mount thehandrail assembly 100. In some embodiments, thetubing sections 110 are positioned approximately 1.5 inches away from the wall when thehandrail assembly 100 is mounted. - To remove the
handrail assembly 100 from thesupports 150, the male andfemale connectors tubing sections 110 are decoupled. In embodiments in which adhesive 160 is used to mounthandrail assembly 100 to thewall 102, thesupports 150 are removed from thewall 102 by tugging on them gently till they become loose. In embodiments in which fasteners are used to attach thehandrail assembly 100 to the wall, the fasteners are removed from the wall to allow thehandrail assembly 100 to be removed and, optionally, to be repositioned. - It should be understood that the steps of assembling, mounting, and removing may be performed in any order. For example, a single section of
tubing 110 and associatedsupports 150 may be mounted to thewall 102. A second section oftubing 110 may then be coupled to the first section oftubing 110 and mounted to thewall 102. Further, thecap 135 and plug 140 may be assembled to the assembly after all of the sections oftubing 110 are mounted to thewall 102. - Although the subject matter has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be construed broadly, to include other variants and embodiments, which may be made by those skilled in the art.
