Title: Safety system including evacuation slide and floatation raft, and methods of use

Description:
BACKGROUND 
     The present invention relates to an emergency or evacuation system that includes an inflatable slide and/or emergency floatation raft to provide safe escape from a building in an emergency situation, such as, for example, a burning building. 
     The use of evacuation slides is known in the prior art. The known evacuation slides are primarily associated with aircraft. Evacuation slides have also been used for buildings. The evacuation slides used for building are generally secured to the exterior of the building which exposes the evacuation slide to the harsh external environment including heat, UV exposure, cold and moisture. Such exposure can be detrimental to the performance and longevity of the slide. 
     Known evacuation slides for building also require installation on the exterior of the building which may require retrofitting the building and add installation costs to the evacuation system. This exists a need for an emergency evacuation system that provides escape from a building in an emergency situation that is cost effective, durable, easy-to-use, in embodiments is portable, and permits safe non-injurious escape. 
     SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION 
     In the following detailed description, numerous details are set forth in order to provide an understanding of an evacuation slide and/or emergency raft, the system, and its method of operation and use. However, it will be understood by those skilled in the art that the different and numerous embodiments of the evacuation slide and/or emergency raft system, and its method of operation and use may be practiced without these specific details, and the claims and invention should not be limited to the embodiments, subassemblies, or the specified features or details specifically described and shown herein. The description provided herein is directed to one of ordinary skill in the art and in circumstances, well-known methods, procedures, manufacturing techniques, components, and/or assemblies have not been described in detail so as not to obscure other aspects, or features of the evacuation slide and/or emergency raft. 
     Accordingly, it will be readily understood that the components, aspects, features, elements, and subassemblies of the embodiments, as generally described and illustrated in the figures herein, can be arranged and designed in a variety of different configurations in addition to the described embodiments. It is to be understood that the evacuation slide and/or emergency raft, and system may be used with many additions, substitutions, or modifications of form, structure, arrangement, proportions, materials, and/or components which may be particularly adapted to specific environments and operative requirements without departing from the spirit and scope of the invention. 
     The following descriptions are intended only by way of example, and simply illustrate certain selected embodiments of a system including an evacuation slide and/or emergency raft. For example, while the evacuation slide and/or emergency raft is shown and described in examples with particular reference to its use in connection with a window opening, and in connection with a fire, it should be understood that the evacuation slide and/or emergency raft will have other applications as well. In this regard, the description utilizes the term inflatable slide but one should recognize that use of the term slide is intended to be inclusive of the system and combination slide/emergency raft. In addition, while the detailed description in many examples is generally directed to an evacuation slide that has features beneficial for use as an emergency raft, it will be appreciated that the disclosure and teachings have application to other materials and designs that would not utilize features beneficial for use as an emergency raft, such as, for example, by eliminating the buoyant foam. The invention shall be set forth by the claims which should be broadly construed to cover evacuation slides and/or emergency rafts, unless otherwise clearly indicated to be more narrowly construed to exclude embodiments, elements and/or features of the evacuation slide and/or emergency raft. 
     Throughout the present application, reference numbers are used to indicate a generic element or feature of the system, evacuation slide, and/or emergency raft. The same reference number may be used to indicate elements or features that are not identical in form, shape, structure, etc., yet which provide similar functions or benefits. Additional reference characters (such as letters, primes, or superscripts, as opposed to numbers) may be used to differentiate similar elements or features from one another. It should be understood that for ease of description the disclosure does not always refer to or list all the components of the system, evacuation slide, and/or emergency raft, and that a singular reference to an element, member, or structure, e.g., a singular reference to a securement strap, raised side portion, safety cable, attachment cord, wheel, support member, may be a reference to one or more such elements, unless the context indicates otherwise. 
     In the following description of various embodiments of the system, evacuation slide, and/or emergency raft, it will be appreciated that all directional references (e.g., proximal, distal, upper, lower, upward, downward, left, right, lateral, longitudinal, front, rear, back, top, bottom, above, below, vertical, horizontal, radial, axial, interior, exterior, clockwise, and counterclockwise) are only used for identification purposes to aid the reader&#39;s understanding of the present disclosure unless indicated otherwise in the claims, and do not create limitations, particularly as to the position, orientation, or use in this disclosure. Features described with respect to one embodiment typically may be applied to another embodiment, whether or not explicitly indicated. 
     Connection references (e.g., attached, coupled, connected, and joined) are to be construed broadly and may include intermediate members between a collection of elements and relative movement between elements unless otherwise indicated. As such, connection references do not necessarily infer that two elements are directly connected and in fixed relation to each other. Identification references (e.g., primary, secondary, first, second, third, fourth, etc.) are not intended to connote importance or priority, but are used to distinguish one feature from another. The drawings are for purposes of illustration only and the dimensions, positions, order and relative sizes reflected in the drawings may vary. 
     With reference to the drawings, and in particular to  FIGS. 1-17 , preferred embodiments of the new and improved inflatable slide and/or emergency raft providing egress in an emergency situation from buildings having egress openings located above a ground surface embodying, disclosing, and teaching various concepts and principles is discussed. It will be noted in the various figures that the device, system and/or method relates to an inflatable slide for providing egress in an emergency situation from buildings, such as, for example, to provide safe escape from a burning building, and/or an emergency raft to provide safety in water conditions, e.g., a flood situation. In one context the device, system and/or method includes an elongated self-inflating slide portion which in one embodiment has an attachment mechanism to secure the slide to the building, preferably the interior of the building, and permit movement of the slide from a ready position inside the building to a deployment position outside the building. In one embodiment, the inflatable slide includes one or more securement cables or straps attachable, preferably releasably attachable, to the slide and attachable, preferably in an embodiment releasably attachable, to the building to secure the inflatable slide to the building. The components and features are individually and collectively configured and correlated with respect to each other to attain the desired objectives. 
     The inflatable slide generally has two states or conditions including a ready state or packaged condition wherein the slide is uninflated and packaged to be smaller, more compact and preferably readily moveable by a user or potential evacuee, and an inflated state or condition where the slide is inflated into a larger size and configured to provide an escape from the floors above ground level in a dangerous situation. During deployment and/or inflation, the slide changes or converts from the ready state to the inflated state. In the inflated state, the slide is usable by potential users and/or evacuees to descend from an egress opening in a building, such as, for example, a window, door, escape hatch, or similar opening, that is located above ground to a ground surface or other location. The slide is also movable from various positions including a ready position inside a building to a deployment position located outside and preferably secured to the building. 
     Turning first to the configuration of the slide in its inflated state or inflated condition, as shown in  FIGS. 1-3 , the slide  10  may comprise an elongated self-inflating slide portion  12 , having an upper end portion  14 , an enlarged lower end portion  16 , and a middle portion  18  extending between the upper end portion and the enlarged lower end portion. The slide portion  12  in one embodiment may include a pair of raised side portions  20  extending a length of the sliding portion  12  and a central sliding portion  22  disposed and located between the raised side portions  20 . The evacuee would slide down the central sliding portions  22  while the raised side portions  20  would resist and help prevent the evacuee from falling off the slide  10 . While it is preferable that the raised side portions  20  run the length of the slide portion  12 , it is contemplated that the raised side portions  20  may extend only the length of the upper end portion  14 , the middle portion  18 , and/or the enlarged lower end portion  16 , or any combination thereof (e.g., the upper end portion  14  and the middle portion  18 ). The width of the central portion  22  in the upper end portion  14  and the middle portion  18  may be about eighteen (18) inches to about four (4) feet wide. 
     The slide portion  12  is configured to have a length that is greater than the distance between the egress opening and the ground surface upon which the enlarged lower end portion  16  is configured to rest upon. The top surface  17  of the middle portion (and/or the top surface  15  of the upper end portion  14 ) preferably forms an obtuse angle “OA” with the ground, and an acute angle “AA” ( FIG. 2 ) between the lower surface  28  of the middle portion and the ground. 
     In an embodiment the inflatable slide and/or portions thereof, including labels, may be color coded to correlate to the length of the slide portion  12 . For example, the color red could be used for the second floor of buildings and may have representative lengths of twenty (20) feet to thirty (30) feet; the color orange could be used for the third floor of buildings and may have representative lengths of thirty (30) feet to forty (40) feet; the color yellow may be used for the fourth floor of buildings and may have representative lengths of forty (40) feet to fifty (50) feet; the color green may be used for the fifth floor of buildings and may have representative lengths of fifty (50) feet to sixty-five (65) feet; the color blue may be used for the sixth floor of buildings and may have representative lengths of sixty-five (65) feet to eighty-five (85) feet; and the color purple may be used for the seventh floor of buildings and may have representative lengths of seventy-five (75) feet to ninety-five (95) feet. Other colors and lengths are contemplated for use. 
     The enlarged lower end portion  16  may be wider than the middle portion  18 , and/or upper end portion  14  as seen in  FIG. 1 . For example, the enlarged lower end portion  16 , may have a width from eighteen (18) inches to about six (6) feet. The enlarged lower end portion  16  preferably provides a landing area  19  for the evacuees and preferably provides a cushioned area. The enlarged lower end portion  16  may have a larger thickness “T” than the upper end portion  14  and/or the middle portion  18 , and in one embodiment the top surface  26  of the enlarged lower end portion  16  is about eighteen (18) inches to twenty-four (24) inches from the lower surface  27  of the enlarged lower end portion  16  which preferably positions the top surface  26  eighteen (18) inches to twenty-four (24) inches above the ground. One purpose of the enlarged lower end portion  16  is to provide a safe landing for evacuee and to prevent or lower the likelihood of injuries. 
     In one embodiment, the enlarged lower end portion  16  may include foam  29 , preferably formed as a layer. The foam may form or be part of the top surface  26  of the enlarged lower end portion. Additionally or alternatively, the foam may be in the interior of the lower end portion  16 , and/or may form or be part of the lower surface  27  of the lower end portion  16  as shown in  FIG. 2 . In one embodiment, the lower surface  24  of the upper end portion  14 , and/or the lower surface  28  of the middle portion  18 , and/or the lower surface  27  of the enlarged lower end portion may have a layer of foam  29 . The layer of foam may be approximately one (1) inch thick of industrial grade foam, preferably highly buoyant foam. The foam may assist the structural integrity of the slide and may provide increased buoyancy in the event of a flood, where the slide can also be deployed as a flotation or emergency raft (See  FIG. 14 ). The layer of foam  29  may also be fire resistant or fire retardant. 
     In one embodiment, the slide portion  12  may comprise a plurality of inflatable chambers  25 , which preferably run the length “L” of the slide portion  12  as shown in  FIGS. 1 and 3 . The plurality of inflatable chambers  25 ,  25 ′ may be independently inflatable. The raised side portions  20  may have inflatable chambers  25  separate and independent from the one or more inflatable chambers  25  forming the central portion  22 . The central portion  22  may include a plurality of chambers  25 ,  25 ′, which are preferably independently inflatable. The enlarged lower end portion  16  may have more chambers  25  than the upper end portion  14 , and/or the middle portion  18 . A plurality of chambers may assist with the structural integrity and rigidity of the slide, and should provide improved reliability and operability in the event that a chamber is defective or punctured or otherwise compromised prior to, during deployment and inflation of, and/or use of the slide  10 . 
     In one embodiment, a safety system is associated with the slide  10  to maintain an evacuee on the slide during their descent. The safety system may include one and preferably a pair of safety cables  30  associated with raised side portions  20  as shown in  FIG. 3 . The safety cables preferably run the length of the raised side portions  20 , but may run more or less than the length of the raised side portions  20 . The safety cables  30  may extend in channels  32  formed within the raised side portions  20 , and the channels may include a flap  34  covering the opening of the channel  32 . Each of the safety cables  30  may have one or more attachment cords  35  slidably coupled thereto. The attachment cords  35  may have hook and loop fasteners disposed thereon for securing the attachment cords  35  to the wrists of users. Other fastening mechanisms for attaching to users is also contemplated. The attachment cords  35  may have one or more loops  36  slidably coupled to the safety cables  30 . The attachments cords  35  may releasably attach to or be associated with the loops  36  to associate or couple the attachment cords  35  to the safety cables  30 . 
     In one embodiment, the upper end portion  14  and/or middle portion  18  forms a tubular or enclosed portion  40  as shown in  FIGS. 4-6 . The tubular portion  40  extends a portion of the length of the slide portion  12  and encloses the top portion of the slide to maintain an evacuee on and within the slide during their descent. The tubular portion  40  is preferred for the longer lengths of the slide, for example slides for greater than three floors. The tubular portion  40  preferably extends until about twenty (20) feet from the ground. The upper portion  42  of the tubular portion  40  may be transparent or translucent and may be formed of fire resistant material or coated with fire resistant material, including fire resistant rubber. 
     In another embodiment, the slide portion  12  on a top surface  11  may include a plurality of raised sections  44  that form rib-like extensions that extend transverse to the length of the slide portion  12 . The plurality of raised sections  44  preferably are dispersed and spread out at a plurality of locations along the length of the slide portion. The raised sections  44  in one embodiment may be provided throughout the tubular potion  40  as shown in  FIG. 6 . The raised sections  44  preferably extends transverse across the central portion  22 , preferably perpendicular to the length of the slide and/or central portion  22 . The plurality of raised sections  44  preferably are sized, configured and spaced to slow and control the descent velocity of an evacuee. In one embodiment, the raised sections  44  may be spaced approximately one foot apart, although other spacing distance are contemplated, which may depend upon the size of the raised sections, the friction of the central portion  22  on which the evacuee slides, and the angle of descent. The raised sections  44  may be advantageous and preferred for the longer length slides to slow the descent of the evacuees to increase the safety and decrease the likelihood of injury. Other factors affecting the descent velocity is the angle the slide forms with the ground and the frictional resistance of the top surface  11  of the slide portion  12  and/or central portion  22 . The raised sections may be formed in embodiments only on a portion of the slide, for example, only the upper portion  14  and/or the middle portion  18 . 
     While the system, inflatable slide, and/or emergency raft is not being used it is in a ready state in a packaged condition. In the ready state as shown in  FIG. 7 , the slide is uninflated, compressed and packaged, preferably so it may be easily moved and deployed. In the packaged condition, the slide is preferably configured to be easily deployed to a deployment position as shown in  FIG. 8 . In one embodiment, the slide in a ready state is folded and rolled into a compact unit which may be readily inflated so that it takes on an inflated state and is configured for use. 
     In an aspect, the slide in the ready state has a release button  50  that is pulled by a user to inflate the slide. In an embodiment, the release button  50  is configured to be pulled by a user to inflate the slide to the inflated state or condition. According to one aspect, as shown in  FIGS. 11 and 11A , pulling the release button  50  releases the pin  51  of one or more compressed gas canisters  54  to release gas to inflate the slide. The slide preferably has a plurality of compressed gas canisters  54  which are spaced along the length of the slide portion  12  as shown in  FIGS. 12B and 12C . The release button  50  is configured as shown in  FIG. 12A  so that as the release button  50  is pulled, tension wires  53  pull the one or more pins  51  on one or more of the compressed gas canisters  54  which releases gas and starts to inflate the slide  10 . As the slide  10  inflates it starts to unfold and unroll as gravity and the pressure from the released gas fills the interior portions of the slide. As the slide unfolds and unrolls, as shown in  FIGS. 9A-9D  and  FIG. 10 , the energy and motion of the unrolling slide releases the pins of additional compressed gas canisters  54  so that the slide continues to unfold, unroll, inflate and extend to the ground until all the pins  51  of the compressed gas canisters  54  are pulled and the slide is fully inflated and deployed as shown in  FIG. 12C . The compressed gas canisters  54  are preferably arranged so that they trigger in sequence as the slide unrolls as it undergoes the inflation process. The pins  51  of the canisters  54  may be arranged so that as the slide unfolds and inflates, movement of the slide portion  12  pulls the release pins  51 , or additionally or alternatively, tension wires may be used to pull the release pins. The upper end portion  14  of the slide preferably inflates before the middle portion  18  or enlarged end portion  16 , with the middle portion  18  thereafter filling with gas, followed by the enlarged lower portion  16  as shown in  FIGS. 9A-9D  and  FIG. 10 . The slide may have one or more compressed gas canisters  54  per inflatable chamber  25 . The enlarged lower end portion  16  may have more gas canisters  54  to fill the larger volume. In one aspect, the compressed gas in the one or more canisters  54  may include CO 2  and preferably is essentially only CO 2 . Other inflation gases, preferably gases that would not create a fire hazard, may be used. Additional to or alternatively, the inflatable slide  10  may include an aspirator  55  associated with and activated by the release button  50  to draw air into the slide portion to inflate the slide  10 . While inflating the slide has been described as utilizing a plurality of compressed gas canisters  54 , it should be appreciated that one compressed gas canister  54  may be utilized depending upon the design and desired characteristics of the inflatable slide. 
     In one embodiment, the slide in the ready state is preferably stored indoors in the interior of the building as shown in  FIG. 7  so that it is not subject to the exterior environmental conditions, which may affect the durability and longevity of the slide. In one aspect, the slide includes a mechanism for securing the slide to the building so that it may be deployed in proximity to an egress opening, e.g., a window, as shown in  FIG. 7 . In one embodiment, the slide in the ready state is secured to the building, preferably to the interior of the building, in a ready position preferably in proximity to an egress opening and moveable to the exterior of the building to a deployment position where the slide may be inflated and deployed as shown in  FIG. 8 . 
     In one embodiment, the slide may include one or more securement cables or straps  58  for securing the slide to the building, preferably the interior of the building.

The securement straps  58  may be as shown in  FIGS. 7 &amp; 8  releasably attachable to the slide, and additionally or alternatively may be releasably attachable to the building. In another embodiment, particularly useful for portable models of the evacuation slide, the securement straps  58  may be U-shaped hook members  80  as shown in  FIG. 13  that grab onto the ledge or sill of the egress opening. The slide  10  in the ready state is preferably positioned in a ready position inside the building but is preferably readily moveable to a deployable position outside the building and secured to the building as shown in  FIGS. 7 &amp; 8 . In this regard, the securement straps  58  are of sufficient length so that the slide in the ready state can be moved from inside the building to outside the building through the egress opening. 
     In one configuration, the slide in the ready state in the packaged condition has the release button  50  arranged and positioned so that it is on the back surface  61  facing the inside wall of the building as shown in  FIG. 7  so that it is not easily accessible in the ready position. In this manner the release button  50  will be less likely to be prematurely and inadvertently released while the slide is inside the building and before the slide is needed. The release button  50  is preferably arranged and positioned on the back surface  61  so that when the slide is in the deployed position the button is facing outside and readily accessible by a user as shown in  FIG. 8 . As shown in  FIGS. 7 &amp; 8 , in the ready position the back surface  61  of the packaged slide faces the interior wall of the building while in the deployed position the front surface  62  faces the outside building wall while the back surface  61  faces outward and is readily accessible by a user. 
     The slide in the packaged condition may further be associated with one or more sensors  65  as shown in  FIGS. 7, 8 and 13  to detect an emergency situation, such as, for example, a fire or smoke condition. The sensors  65  may be associated with the packaging  66 , which retains the slide in the ready state. The sensors  65  may be associated with an alarm  68 . The alarm  68  may provide a visible and/or auditory alert. The sensor  65  may detect heat, smoke, CO 2 , or other conditions that may indicate a dangerous situation. For example, the alarm(s)  68  may provide auditory instructions, flash, provide siren noises, and/or beep. The sensors may flash different colors, for example, yellow, white, and/or red. The sensors  65  and alarms  68  may be associated with or on a top surface of the packaging  66  in the ready state to facilitate detecting smoke, heat, CO 2 , and other conditions.
