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.
In some embodiments, the handrail assembly 100 comprises at least one length of tubing 110. The tubing 110 can be constructed of any appropriate material, such as, for example, plastic. The handrail assembly 100 may comprise a strong but lightweight flexible plastic tubing 110 that will not decrease in strength after months of repeated use and can endure substantial weight. The tubing 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. The handrail assembly 100 can include a single length of tubing 110, or a plurality of lengths of tubing 110 joined end-to-end with each other.
The handrail assembly 100 can be secured to a wall 102 with external supports 150. Each support 150 has a flat plate or flange 152 for mounting the support 150 to the wall 102. In some embodiments, the supports 150 comprise heavy duty plastic, such as PVC, polyurethane, polyethylene, ABS, polycarbonate or the like. In other embodiments, the supports 150 comprise a metallic material, such as aluminum, steel, stainless steel, or any other appropriate material.
In some embodiments, as shown in
As shown in
The supports 150 have a second flange 154 for attaching the tubing 110 to the supports 150. In some embodiments, the second flanges 154 are joined to the tubing 110 using fasteners 156 (e.g., screws) (shown in
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 of tubing 110 may also be any appropriate length.
In some embodiments, as shown in
In various embodiments, a sleeve 120 comprising any of the above materials can be coated with an anti-microbial coating. A foam sleeve 120 with antimicrobial coating acts as a protective covering that provides a comfortable and firm grip for the child. The antimicrobial coating on the sleeve 120 can also prevent the spreading of germs and inhibits microorganisms from growing. For example, in some embodiments, the sleeve 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), the sleeve 120 is a single piece having a continuous circumference. In other embodiments (not shown), the sleeve 120 can comprise a plurality of sleeve sections, where each sleeve section is shorter than the complete handrail assembly 100. These shorter sleeve sections may be easier to slide longitudinally over the tubing 110 of handrail 100, because of smaller contact area per sleeve section. In some embodiments, as shown in
In other embodiments, as shown in

As shown in
The use of a modular design allows multiple sections of the plastic tubing 110 to be joined to increase the length of the handrail assembly 200 to accommodate any size of staircase 101. The external supports 150 can be “L” or arch shaped to allow a user to slide his/her hand up and down the cylindrical tubing 110 without interference. The supports 150 may have extended and raised portions to provide clearance for the user's hand. Each end of cylindrical handrail assembly 100 or 200 may include a fitted covering component 135, 140, which couple to connecting members 130, 145 to cover the open ends of cylindrical tubing sections 110 that are not functioning as a connector member between adjoining sections of tubing 110 of a multi-section handrail assembly 200. For example, the covering component 135 can be a cap covering an exposed male connector 130 and the covering component 140 can be a plug filling an exposed female connector 145. In other embodiments, the cap 135 and/or plug 140 have a “snap fit” connector that locks securely in place.
In one embodiment, an adjustable walking device/handrail assembly 100 includes an elongated, lightweight cylinder of tubing 110 encased in an antimicrobial coated memory foam sleeve 120. The anti-microbial memory foam outer sleeve 120 on the tubing 110 conforms and molds to the shape of the toddler's hand, which allows the child's grip to be firm and comfortable. The handrail assembly 100 aids toddlers/children by providing support to ascend and descend a staircase 101. The handrail assembly 100 may assist toddlers in improving their balance.
In some embodiments, the handrail assembly 100 includes a non-screw type wall mounting 160 which makes the handrail assembly 100 easily detachable and re-locatable. The support 150 can include a flange 152 with a pressure-sensitive adhesive 160. In various embodiments, the handrail assembly 100 has no mechanical or magnetic connection or association with an existing permanent handrail 104 (
In some embodiments, a vertically elongated cylindrical plastic tube 110 is encased in antimicrobial coated “DURAFOAM™” closed cell sponge rubber and plastic foam or an LRPu memory foam sleeve 120 that spans the length of the staircase 101. The handrail assembly 100 can include one or more tubing sections 110, each having a first end and a second end. Each section of tubing 110 can include a male connector 130 at one end and a female connector 145 at an opposite end. The male and female connectors 130, 145 can fasten to the tubing section 110 or to one another. Any desired number of sections of tubing 110 having female 145 and male 130 connectors can be assembled together to add length to match the length of an existing permanent handrail 104 in the desired area of placement. In other embodiments, each end of the tubing sections 110 includes a fitted covering component (e.g., cap 135 or plug 140) to cover the free end thereof.
Features and advantages of the embodiments will become apparent from specifications of drawings by way of illustration, which are individually obtained by various embodiments and features of the drawings.
Operation
In various embodiments, the user assembles the handrail assembly 100 prior to mounting the handrail assembly 100 to the wall. In embodiments in which more than one section of tubing is desired, the user joins two or more tubing sections 110 by inserting the male projection 130c of male connector 130 into the aperture 145c of the female connector 145, for example. The cap 135 may then be placed over the exposed male connector 130, and the plug 140 is placed in the open female connector 145. The foam sleeve 120 is placed over the tubing 110. The sections of foam 120 can slide longitudinally over the tubing 110, or the foam sleeve 120 is slit longitudinally (with a longitudinal slit 126) and is wrapped around the tubing 120. The tubing 110 is then attached to the supports 150.
The handrail assembly 100 is then attached to the wall 102 above the stairs 101. In embodiments having adhesive 160, release paper (not shown) may be removed from the pressure sensitive adhesive 160. The flanges 152 may then be pressed against the wall 102 to couple the handrail assembly 100 to the wall 102. In embodiments, such as shown in
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 the supports 150, for example) using a pressure-sensitive adhesive or fasteners to mount the handrail assembly 100. In some embodiments, the tubing sections 110 are positioned approximately 1.5 inches away from the wall when the handrail assembly 100 is mounted.
To remove the handrail assembly 100 from the supports 150, the male and female connectors 130, 145 of the tubing sections 110 are decoupled. In embodiments in which adhesive 160 is used to mount handrail assembly 100 to the wall 102, the supports 150 are removed from the wall 102 by tugging on them gently till they become loose. In embodiments in which fasteners are used to attach the handrail assembly 100 to the wall, the fasteners are removed from the wall to allow the handrail 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 associated supports 150 may be mounted to the wall 102. A second section of tubing 110 may then be coupled to the first section of tubing 110 and mounted to the wall 102. Further, the cap 135 and plug 140 may be assembled to the assembly after all of the sections of tubing 110 are mounted to the wall 102.
