The present invention is an improved safety nosing component including a base element with channel member and a light emission element. The safety nosing component is manufactured by extrusion, co-extrusion, triple-extrusion, injection molding, insert injection molding, two-shot molding or a combination thereof. The present invention allows safety nosing components to be installed on architectural structures while also providing additional functionality.

Description

  • This application claims the benefit of U.S. Provisional Application No. 61/005,739 filed Dec. 7, 2007.
  • FIELD OF THE INVENTION
  • The present invention relates generally to safety components and more particularly to nosing components for architectural structures and improved manufacturing thereof.
  • BACKGROUND OF THE INVENTION
  • Safety devices are used on architectural structures in a variety of environments to reduce risk. Many environments exist where various poor lighting scenarios occur, for example, dimmed lighting or darkness due to a power failure or smoke resultant from a fire. Risks may occur when people attempt to navigate in poorly lit environments; such risks include physical injury, lack of orientation, lack of information regarding navigation and lack of familiarity with the environment. To, mitigate these risks, illuminated safety devices exist that are typically installed on stairs, floors, walls, and handrails such as that disclosed in application Ser. No. 12/215,971 filed Jul. 1, 2008, entitled Safety Handrail Apparatus and Manufacturing Methods, incorporated herein by reference.
  • But, these prior art devices are deficient in several respects including limitations in design, manufacturability and functionality. One limitation is due in part to material compositions of the device. For example, U.S. Pat. No. 4,522,861 requires a material mixture including zinc sulfide, copper phosphorescent pigment, bleached aluminum oxide and silicon carbide; U.S. Pat. No. 5,904,017 requires a material including a transparent resin mixed with zinc sulfide particles; and U.S. Pat. No. 5,103,608 requires lumilux-N pigment carried by a two part epoxy.
  • Another limitation of the prior art devices is due in part to material requirements such as an adhesive. For example, U.S. Pat. No. 6,632,506 requires traction tape with an adhesive; and U.S. Pat. No. 4,360,557 requires a laminate with a pressure sensitive adhesive.
  • Yet another limitation of the prior art devices is due in part to inflexibility in design, which further results in costly and time-consuming manufacturing. For example, U.S. Pat. No. 5,898,814 includes a device with multiple parts including an illuminating plane to emit light that is reflected by a reflecting member; U.S. Pat. No. 4,058,942 includes a device that requires a transparent covering strip positioned over a fluorescent material strip; and U.S. Pat. No. 6,554,446 includes a device that requires electrically activated light sources such as seat-mounted lamps, or beacon lamps.
  • These prior art devices are limited in functionality by only serving as a safety device. There is a desire for improved safety nosing components that provide other functionality, for example, a non-slip surface, dock boat bumper, illumination guide, an illuminated boat fender or advertising medium.
  • While the prior art devices fulfill their respective particular objectives and requirements, the need still remains for safety nosing components and manufacturing methods thereof that fulfill the deficiencies of these devices and provide additional functionality. The present invention satisfies this need.
  • SUMMARY OF THE INVENTION
  • The improved safety nosing component and methods of the present invention fulfill the deficiencies in design, manufacturability and functionality of prior art devices. The present invention includes improved material compositions and material requirements. Additionally, the present invention is flexible in design thereby reducing cost and time associated with manufacturing. Embodiments according to the present invention contemplate one-step, two-step, or three-step manufacturing processes. Certain embodiments of the present invention may also provide functionality in addition to a visual safety marker.
  • For purposes of this application, an architectural structure is any physical formation. The present invention is discussed herein with respect to steps, decks and docks, but any physical formation is contemplated such as floors, walls, ceilings, piers, decks, balconies, hallways, bridges, wharfs, landings, platforms, fences, ladders, stairways, escalators, elevators, parking lots, boats, ships, planes, automobiles, and arenas just to name a few. It is further contemplated the present invention can be the architectural structure itself such as a stake or post, for example, a deck post and sign post.
  • The safety nosing component may be attached to an architectural structure of any construction, such as wood, composite wood, cement, fiberglass, plastic, metal, concrete, steel, stone, brick, glass, asphalt, carpet to name a few. The safety nosing component may be portable or permanently secured to an architectural structure such as by using hardware including screws or nails, adhesive including liquid or tape adhesive, or Velcro®. The safety nosing component may further include an attachment member to assist with securement to an architectural structure.
  • In one embodiment, the safety nosing component according to the present invention includes a base element and a photoluminescent light emission element. Additional embodiments may further include a substrate element.
  • The base element, in one embodiment, includes a main member with an inside surface, outside surface, first edge, second edge, third edge and fourth edge. It is contemplated any of the edges of the main member may include a bevel feature, for example, to prevent shoes or feet from catching on the safety nosing component. According to the present invention, the base element may be any length, width, depth, shape or size. For example, in one embodiment, the base element may be about and including 3 feet to about and including 12 feet in length. In another embodiment, the base element may be about and including 20 feet or greater in length.
  • In another embodiment, the base element includes a main member as described above as well as a support member. The support member includes an interior surface, exterior surface, first border, second border, third border and fourth border. It is contemplated any of the borders of the support member may include a bevel feature, for example, to prevent shoes or feet from catching on the safety nosing component. The main member and support member unite at an edge of the main member and a border of the support member. The main member and support member are united such as to form approximately a ninety-degree angle between the two elements, although any angle resultant from the application of the safety nosing component is contemplated.
  • In another embodiment of the present invention, an edge of the main member and a border of the support member are united via a living hinge member. A living hinge member is a thin flexible hinge that may be formed during manufacturing such as by injection molding or may be a separate part such as a thin strip of material, such as thermoset or thermoplastic resin, polyethylene or polypropylene, that is molded into the component to create a line along which the component can bend. Properly designed and executed, the living hinge member can be closed and opened over the life of the component with little or no loss of function.
  • The base element includes a channel member extending from a proximate end to a distal end and is formed by boundaries. The channel member may be positioned on either the main member or support member of the base element. More specifically, the channel member may be positioned on the outside surface of the main member or the exterior surface of the support member. The channel member may run along the entire length or a portion of the entire length of the outside surface of the main member or exterior surface of the support member.
  • Any depth of the channel member is contemplated in order to receive the light emission element. It is further contemplated that the channel member can be any cross-sectional shape such as dovetail, triangular, square, to name a few. The channel member may be, for example, about and including ½ inches to about and including 2½ inches in width.
  • The light emission element is any length, width, depth, shape or size for positioning within the channel member of the base element. The light emission element stores energy, for example, as by absorbing photons and releasing the energy as light over a duration of time. The light emission element is capable of producing a sustained visible glow including in darkness such as at a minimum of one hour or longer. According to the present invention, the light emission element is a material with a fluorescent or photoluminescent quality, for example, strontium oxide, strontium aluminate, strontium silicate with magnesium or metal sulfides such as calcium sulfide, strontium sulfide, zinc sulfide, and cadmium sulfide. The light emission element may further be a metal or polymer.
  • The base element and light emission element of the present invention are made of any material that can be molded or extruded, for example metal such as aluminum or powdered metals, composite lumber, and polymers, thermoset or thermoplastic resins. Polymers include plastics such as thermoplastic, thermoset plastic, polyurethane, polyethylene, polypropylene and engineering plastic, for example, synthetic polymers including nylon. The materials may further be compounded with a glass fiber or powdered metal to maintain rigidity such that the component does not warp or twist during manufacturing or installation.
  • The material used for the safety nosing component is easily cut, for example on a table saw or miter saw, to form various configurations such as to accommodate varying lengths or corners. It is further contemplated that the material may be cured by a radiation source such as ultraviolet (UV) light or contain a UV additive in the material. Additionally, the material may be impact modified to improve the material properties such as wear, non-slip, and weatherability, for example 2000 kilojewels of weatherability. The material may also be compounded with a flame retardant additive to meet certain fire codes and regulations.
  • The materials used to manufacture the present invention may further be compounded with any color concentrate. This contemplates color matching, such as deck stains, paints, and composite lumber colors. The entire safety nosing component may be manufactured with any color concentrate, including those that emit light such that the entire component illuminates.
  • In another embodiment of the present invention, the safety nosing component further includes a substrate element. The substrate element includes a top face and a bottom face along with a first side, second side, third side and fourth side. The substrate element according to the present invention is made of any material that can be molded or extruded, for example metal such as aluminum, or polymers. Additionally, the substrate element may include a substance such as a film, pad, metal, grit or tape such as a pre-finished, cut to size, non-skid friction substance and may further include a self adhesive backing used in co-extrusion or triple-extrusion processes. The substrate element is any length, width, depth, shape or size to be positioned adjacent to the light emission element. The advantages of a substrate element are that it may optimize the illumination of the light emission element by preventing the base element from “bleeding through” the light emission element. In a preferred embodiment, the substrate element is white although any color is contemplated to achieve the advantages discussed herein.
  • For purposes of this application, the term “light emission element” used herein may include either the light emission element or the light emission element including substrate element.
  • The light emission element includes an upper face and a lower face along with a first wall, second wall, third wall, and fourth wall. Although numerous configurations are contemplated, in a preferred embodiment the light emission element, is positioned substantially about the channel member and is about and including ½ inches to about and including 2½ inches in width and runs along the entire length or a portion of the entire length of the channel member.
  • In another embodiment, the present invention allows configuration into any desired length or shape by interconnecting any number of individual nosing components. For example, a first nosing component may be interconnected to a second nosing component and so on to form a continuous linear component or to form a corner component for architectural structures with bends or curves. Interconnection includes insert injection molding, overmolding, heat stake, weld, snap fit such as annular snap fit or cantilever snap fit, adhesive, adhesive tape, fasteners, chemical bonding, mechanical fit, or interference fit. For purposes of this application, the term “weld” includes sonic weld, vibration weld, orbital weld, ultrasonic weld, frictional weld, spin weld, radio frequency weld and laser weld, to name a few.
  • The present invention is manufactured by extrusion, co-extrusion, triple-extrusion, injection molding, insert injection molding, or two-shot molding. Extrusion is a process for manufacturing wherein material is pushed or drawn through a die in the desired shape of a fixed cross-sectional profile of the component. The component is cooled and solidified as it is pulled through the die. According to the present invention, the base element, the substrate element and light emission element may each be extruded.
  • Co-extrusion is the manufacturing process of extruding two or more materials through a single die with two or more orifices arranged so that the two or more materials, which may further be of different color, merge and weld together. Each material is fed to the die from a separate extruder, but the orifices may be arranged so that each extruder supplies two or more plies. Each ply may be of the same material, or each ply may be of different materials such as one ply of a polymer material and the other ply of a non-skid friction substance that is co-extruded upon the polymer material. In one embodiment according to the present invention, the base element and the light emission element are co-extruded using two plies to achieve the safety nosing component. In another embodiment, the base element and the substrate element are co-extruded. In yet another embodiment, the light emission component and substrate element are co-extruded.
  • Triple-extrusion is the manufacturing process similar to co-extrusion, except that three or more materials are extruded through a single die with three or more orifices arranged so that the three or more materials merge and weld together. The three or more materials of a triple-extrusion process may each be of different color or may each be of different material. Each material is fed to the die from a separate extruder, but the orifices may be arranged so that each extruder supplies three or more plies. Each ply may be of the same material, or each ply may be of different materials, for example, one ply of a photoluminescent polymer, one ply of aluminum, and one ply of a different material, such as a non-skid friction substance, tape substance, shiny metal, or a white polymer. An embodiment according to the present invention includes triple-extruding the base element, substrate element and light emission element.
  • It is also contemplated that the elements of the present invention can include a texture element created by a calendering process during the extrusion, co-extrusion, or triple-extrusion process. Calendering includes a series of hard or heat-treated pressure rollers used to create a texture element, for example on the outside surface of the main member of the base element, the exterior surface of the support member of the base element, the upper face of the light emission element, or top face of the substrate element. A texture element includes, for example, cleats, ridges, or grooves to form a non-slip surface tread, dock illumination guide, dock bumper, a boat fender or advertising constituent. An advertising constituent may be the advertisement itself or a pocket for receiving an advertisement. The embodiments of the present invention that include a dock bumper provides additional functionality of cushioning an impact of an incoming water vessel. The embodiments of the present invention that include an advertising constituent provides additional functionality of an advertising medium. For example, an advertisement may be positioned on or within the base element or light emission element. An advertisement may even be positioned on or within the substrate element.
  • It is further contemplated that the elements of the present invention can include a texture element created by a laser etched detail during injection molding, insert injection molding, or two-shot molding.
  • Injection molding is a manufacturing process for making components by injecting materials at high pressure into a mold shaped as the inverse of the desired shape of the component. In one embodiment, the base element and light emission element are individually injection molded. In another embodiment, the base element, substrate element and light emission element are individually injection molded. The elements are then interconnected.
  • Interconnection includes insert injection molding, overmolding, heat stake, weld, snap fit such as annular snap fit or cantilever snap fit, adhesive, adhesive tape, fasteners, chemical bonding, mechanical fit, or interference fit. For purposes of this application, the term “weld” includes sonic weld, vibration weld, orbital weld, ultrasonic weld, frictional weld, spin weld, radio frequency weld and laser weld, to name a few.
  • It is also contemplated that certain elements are extruded and others are injection molded after which the elements are interconnected. For example, the base element is extruded and the light emission element is injection molded or the base element is injection molded and the light emission element is extruded. Other examples include a co-extruded base element and substrate element and an injection molded light emission component, or a co-extruded light emission element and substrate element and an injection molded base element.
  • Insert injection molding is a manufacturing process that includes an insert part that is placed into the mold cavity prior to injecting material to encapsulate the insert part. According to the present invention, the insert part may be the base element, the light emission element, the light emission element and substrate element, or the base element and substrate element. The insert part may be manufactured, for example, by extrusion, co-extrusion, injection molding, or even formed applications wherein a malleable material such as metal is formed into a desired any length, width, depth, shape or size. In one embodiment, the insert part is the base element such that the light emission element or light emission element and substrate element is injected molded to encapsulate the insert part. For example, the light emission element is insert injection molded into an aluminum metal base element. In another embodiment, the insert part is the light emission element such that the base element or base element and substrate element is injected molded to encapsulate the insert part. In another embodiment, the insert part is the light emission element and substrate element such that the base element is injected molded to encapsulate the insert part. In yet another embodiment, the insert part is the base element and substrate element such that the light emission element is injected molded to encapsulate the insert part.
  • Two-shot injection molding allows the production of a component from two different materials, which may further be of different color, at the same time during one machine cycle. The two different materials may be joined to form the component, for example, through a heat and pressure process or bonded through mechanical interference. In one embodiment, the base element and light emission element are manufactured with a two-shot injection molding process. In another embodiment, the base element and substrate element are two-shot injection molded. In yet another embodiment, the substrate element and light emission element are two-shot injection molded.
  • In one embodiment of the present invention, the safety nosing component is overmolded, otherwise referred to as in-molded. Overmolding improves efficiency and can be achieved with injection molding, insert injection molding, or two-shot molding manufacturing processes. With overmolding, only one element of the component is molded in one material, and that element is manipulated so an additional material can be molded around, over, under, or through it to complete the final component.
  • In embodiments that include a substrate element, the light emission element and substrate element may be manufactured using extrusion, co-extrusion, injection molding, insert injection molding and two-shot injection molding. The light emission element including substrate element are then assembled with the base element such as by insert injection molding. In embodiments where the base element is manufactured via extrusion, injection molding, or insert injection molding, the light emission element including substrate element are interconnected to the base element. Again, interconnection includes insert injection molding, overmolding, heat stake, weld, snap-fit such as annular snap fit or cantilever snap fit, adhesive, adhesive tape, fasteners, chemical bonding, mechanical fit, or interference fit.
  • Other embodiments include separately manufacturing each of the base element, light emission element and substrate element such as by extrusion, injection molding or insert injection molding. Then, the light emission element, substrate element and base element are interconnected.
  • Yet other embodiments may include manufacturing the base element and substrate element such as by co-extrusion, injection molding, insert injection molding, or two-shot molding. The light emission element may then be assembled with the base element such as by insert injection molding. In embodiments where the light emission element is manufactured via extrusion, injection molding, or insert injection molding, the light emission element is interconnected to the base element including substrate element.
  • Yet other embodiments may include a base element of a malleable material such as aluminum that can manufactured using forming processes. The light emission element may then be interconnected on the base element. Metal forming processes include: stamping, bending, spinning, stretching, drawing, ironing, wheeling, roll forming, and incremental sheet forming.
  • Other embodiments may include co-extruding a polymer material and a non-skid friction substance such that the non-skid friction substance only covers a portion of the polymer material. The co-extruded non-skid friction substance and polymer material are insert molded into the base element, wherein the base element overmolds the portion of the polymer material without the non-skid friction substance such that the non-skid friction substance is flush with the base element.
  • An object of the present invention is to provide an improved safety nosing component that complies with all current and future contemplated industry standards and specifications, including Property Services Agency (PSA), International Building Code (IBC), National Fire Protection Association (NFPA), International Code Compliance (ICC), American National Standards Institute (ANSI), International Residential Code (IRC), and American with Disabilities Act (ADA).
  • Yet another object of the present invention is to reduce risks that may occur when people attempt to navigate in poorly lit environments. The present invention provides components that function as a safety egress or ingress pathway to quickly evacuate people in the case of an emergency.
  • Another object of the present invention is to provide components that serve additional functions such as a non-slip surface, dock bumper for boats, illumination guide, an illuminated boat fender or advertising medium.
