Patent Application
20060162070
The present invention relates to furniture for locating and evacuating people from a dangerous condition such as a fire and, more particularly, to portable infant cribs and portable evacuation cribs with a visual identifier for easily locating the cribs in low light conditions for evacuating one or more juveniles from a dangerous environment.
Traditionally, cribs have been designed to contain and provide a safe sleeping environment for children. In addition, other features have been added in both full-size and non-full-size cribs including the addition of sliding drop sides, hinged drop sides, and adjustable height mattress supports. Further, some cribs have been designed for easy conversion into a youth bed for extended use. Traditionally, cribs are made of wood slat construction, steel tubular construction, or mesh and fabric supported by a frame structure construction.
Although most cribs are sold for use in the home or in a residential environment to provide for a sleeping environment for children, other cribs are sold into institutional environments such as in day care centers, nursery schools, and hotels. In institutional and commercial environments, however, safety precautions necessitate the formulation of an evacuation plan to quickly identify and evacuate children from the building in the event of a fire or other disaster. In support of this, manufacturers and distributors of cribs for institutional or commercial use also provide a separate evacuation frame that can be added to selected cribs in the nursery designated as evacuation cribs. Those cribs thus outfitted with the evacuation frame are useful for evacuation of several children contained in the crib as a group. This expedites the evacuation process.
However, in keeping with the need to provide for a quick evacuation of children in a disaster situation, identification of cribs in a darkened room is a critical element in that process. The identification of the cribs, particularly the evacuation cribs, in an emergency situation must be expedited.
Cribs used in commercial applications such as for hotel use are typically formed of either wood, steel, or a fabric and mesh construction. More particularly, for a fabric and mesh crib the portable crib frame includes a fabric and mesh material supported by a set of substantially rigid outer frame members. Rescue workers in an emergency must be able to quickly locate and identify these cribs as well. However, they are typically at a disadvantage because it is difficult for hotels to maintain an accurate list of crib usage at any given time. The workers must therefore search for those cribs using specialized spotlights and the like.
Accordingly, there is a need in the art for providing on cribs and other furniture a means for generating a locating signal such as a visual identifier or other signal or beacon for drawing attention of rescuers to the furniture for purposes of evacuation or locating children. In addition, by being easily located and identified, the evacuation cribs allow rescue workers to quickly locate children and carry them away from the threatened area. The visual identifiers may contain intelligible information as well for instructing rescuers during an emergency.
U.S. Patent Application Publication No. US 2003/0229940 describes stationary bunk beds having ornamental glow-in-the-dark members. The bunk beds, however, are not practical for purposes of evacuation since they are not portable. In addition, the glow-in-the-dark components of the stationary bunk beds are for purposes of entertainment and, with regard to younger children, to allow their bedroom to glow for several minutes after a light is turned off, thereby giving them a sense of pleasure and free them from fear. Therefore, the bunk beds taught there have no practical application in the case of an emergency evacuation.
In accordance with the present application, portable infant cribs and portable evacuation cribs are provided having a visual identifier means for enabling searchers or rescuers to locate the cribs in low light conditions. The evacuation crib includes a crib frame and a mattress support connected with the crib frame. The mattress support is adapted to support an associated mattress relative to the crib frame. Wheels may be provided on the crib frame as desired for adapting the frame to be rolled along an associate support surface. The portable mesh and fabric cribs such as those used for commercial applications including hotel use provide a frame and structure to provide a safe sleeping environment and may include wheels as desired. Those cribs may also be formed of a fabric and mesh construction supported by a set of substantially rigid plastic or steel outer frame members. A visual identifier is disposed on a one of the crib frame and the mattress support, but preferably on an outside surface of the crib frame inaccessible to children within the crib, but visible to rescuers. The visual identifier is adapted to generate a locating signal visible to humans for locating the crib in a diminished light environment. Accordingly, the present application provides a portable infant crib and a portable evacuation crib with a visual identifier for enabling safety personnel to quickly locate the crib in the dark such as during fires or other catastrophes. The visual identifier may also be fashioned to communicate information, such as evacuation instructions, to the recess.
In accordance with one aspect of the invention, the visual identifier provided on the portable infant crib and on the evacuation crib is a photoluminescent material, a reflective material, or a battery powered indicator applied to the crib such as on the crib frame or on fabric or other portions of the crib.
In accordance with another aspect, the visual identifier includes a panel carried on the crib frame with a photoluminescent or reflective material applied to the panel.
In accordance with yet another aspect of the application, the photoluminescent material is either a visibly phosphorescent material or a visibly fluorescent material. In visibly phosphorescent materials, luminescent radiation continues after termination of the exciting radiation. In visibly fluorescent materials, the luminescent radiation ceases as soon as the exciting radiation is removed. Preferably, the photoluminescent material is visibly phosphorescent after exposure to exciting radiation in the visible range. Thus, the visual identifier glows in the dark in the event of a diminished light environment or total darkness such as during a fire, catastrophe, or other emergency. The visual identifier is thus used as a visual identifier means for locating the crib in low light conditions.
In accordance with yet another aspect of the invention, the reflective material applied onto the portable cribs is highly reflective for providing a visual identifier of the crib. Because of the high reflectivity of the material, the reflected light is highly visible and is easily generated when light is directed at the crib from a light source such as a flashlight, searchlight, or the like. In many commercial applications such as in hotel use, the searchers are not favored with information regarding the location of the infants or cribs and thus must search for them in typically low light conditions. Accordingly, the reflective material provides a means for locating the cribs in low light conditions for emergency evacuation of the children from the crib or of the children contained within the crib together, as desired.
In accordance with yet a further aspect of the application, the visual identifier is provided in association with a child crib in an area non-accessible to the child. Since children are known to chew or mouth surfaces and to pull on or put items that are in their environment into their mouths, the visual identifier is placed on a surface that is not accessible to the occupants of the crib.
In accordance with another aspect of the invention, the visual identifier is protected from access by a child by covered by another part of the crib such as a clear teething rail cover, placed in a recess or stapled, screwed, or covered at the ends to prevent access to the corners for picking.
