Definitions
- the disclosure generally relates to containers for aircraft emergency equipment and to methods of changing aircraft emergency equipment, and more specifically to containers for aircraft emergency escape slides and methods of changing aircraft emergency escape slides.
- Modern passenger aircraft require quick egress options in case of emergency. Because many modern passenger aircraft have entry doors that are ten feet or more above ground level, passengers need some sort of device to allow them to get to the ground safely.
- Inflatable emergency escape slides have been used for this purpose.
- the emergency escape slide is usually made from an inflatable flexible material. When not inflated, the emergency escape slide is folded up into a small volume and stored in or near the egress door. When needed, the emergency escape slide is filled with a gas so that it inflates to a semi-rigid slide structure that extends from the egress door to the ground. While this solution to speedy egress of a passenger aircraft has generally been very successful, the emergency escape slides require periodic checking, maintenance, and/or replacement to ensure that the emergency escape slides will operate correctly in the case of an emergency.
- these emergency escape slides can weigh 100 to 150 lbs (45-68 kg) or more. Moreover, these large passenger aircraft can have eight or more emergency escape slides.
- maintenance personnel In order to change or maintain these emergency escape slides, maintenance personnel must carry a folded slide into the aircraft through the egress door. After entering the aircraft, the folded slide must be carried down an aircraft aisle to the correct egress door. Once position by the correct egress door, maintenance personnel must remove the old slide and then lift and position the new slide in the correct location. Often during transport of the new slide to the correct egress location, the new egress slide can become hooked or torn on various aircraft parts, which would require a new slide to be obtained. Additionally, due to the weight of the slides, maintenance personnel are often injured during the transfer process by bending over to pick up the slide off of the ground.
- the slides are stored in a wooden container that is liftable by a forklift. These wooden containers are very heavy and not very durable. Furthermore, lifting the slide out of the wooden container requires maintenance personnel to bend over, which subjects the maintenance personnel to the possibility of back or other injuries. These injuries result in a loss of workdays and a loss of efficiency, which can be a problem for the employer.

Abstract
Description
- This application is a Continuation of U.S. application Ser. No. 13/836,127, entitled “Aircraft Emergency Slide Container and Method of Changing an Aircraft Emergency Escape Slide,” filed Mar. 15, 2013, which is incorporated herein by reference in its entirety.
- The disclosure generally relates to containers for aircraft emergency equipment and to methods of changing aircraft emergency equipment, and more specifically to containers for aircraft emergency escape slides and methods of changing aircraft emergency escape slides.
- Modern passenger aircraft require quick egress options in case of emergency. Because many modern passenger aircraft have entry doors that are ten feet or more above ground level, passengers need some sort of device to allow them to get to the ground safely. Inflatable emergency escape slides have been used for this purpose. The emergency escape slide is usually made from an inflatable flexible material. When not inflated, the emergency escape slide is folded up into a small volume and stored in or near the egress door. When needed, the emergency escape slide is filled with a gas so that it inflates to a semi-rigid slide structure that extends from the egress door to the ground. While this solution to speedy egress of a passenger aircraft has generally been very successful, the emergency escape slides require periodic checking, maintenance, and/or replacement to ensure that the emergency escape slides will operate correctly in the case of an emergency.
- In large passenger aircraft (in particular in wide-body, long range aircraft), these emergency escape slides can weigh 100 to 150 lbs (45-68 kg) or more. Moreover, these large passenger aircraft can have eight or more emergency escape slides. In order to change or maintain these emergency escape slides, maintenance personnel must carry a folded slide into the aircraft through the egress door. After entering the aircraft, the folded slide must be carried down an aircraft aisle to the correct egress door. Once position by the correct egress door, maintenance personnel must remove the old slide and then lift and position the new slide in the correct location. Often during transport of the new slide to the correct egress location, the new egress slide can become hooked or torn on various aircraft parts, which would require a new slide to be obtained. Additionally, due to the weight of the slides, maintenance personnel are often injured during the transfer process by bending over to pick up the slide off of the ground.
- Additionally transportation and storage of the slides when not installed in an aircraft can be a problem. Typically, the slides are stored in a wooden container that is liftable by a forklift. These wooden containers are very heavy and not very durable. Furthermore, lifting the slide out of the wooden container requires maintenance personnel to bend over, which subjects the maintenance personnel to the possibility of back or other injuries. These injuries result in a loss of workdays and a loss of efficiency, which can be a problem for the employer.
- In accordance with one exemplary aspect of the invention, an emergency escape slide container includes a first portion having a first end wall and a first side wall, the first side wall and the first end wall defining a first storage space that is sized and shaped to receive an emergency escape slide. The first storage space includes a first restraining mechanism for the emergency escape slide. The first side wall includes a first rolling mechanism. The emergency escape slide container also includes a second portion having a second end wall and a second side wall, the second side wall and the second end wall defining a second storage space sized and shaped to receive the emergency escape slide. The second storage space includes a second restraining mechanism for the emergency escape slide. The second side wall includes a second rolling mechanism. The first portion and the second portion cooperate to define a third storage space therebetween, the third storage space being equal to a combination of the first storage space and the second storage space.
- In further accordance with any one or more of the foregoing aspects, an emergency escape slide container may include any one or more of the following preferred forms.
- In one preferred form, the emergency escape slide container may include an emergency escape slide disposed within the first storage space.
- In another preferred form, the first rolling mechanism may include a first roller and a second roller, the first roller may be an omni-roller and the second roller may be a cylindrical nylon roller.
- In yet another preferred form, an outer surface of the first portion may include a first recessed groove, the first recessed groove being sized to receive a fork of a forklift.
- In yet another preferred form, the emergency escape slide container may include a skid mounted on the first portion, the skid extending outward away from an outer surface of the first end wall.
- In yet another preferred form, the emergency escape slide container may include a recess on the outer surface of the first end wall, the recess being sized and shaped to receive a portion of a skid.
- In yet another preferred form, the emergency escape slide container may include a skid that is removably attached to the first portion with a removable fastener, in some preferred forms the fastener may be a thumb nut.
- In yet other preferred forms, the first side wall may include a first plurality of tongues and a first plurality of grooves and the second side wall may include a second plurality of tongues and a second plurality of grooves, the first plurality of tongues being sized and shaped to be received by the second plurality of grooves and the second plurality of tongues being sized and shaped to be received by the first plurality of grooves. In other preferred forms, the first plurality of tongues and the second plurality of grooves may be arranged to locate the first rolling mechanism on an opposite side of the container from the second rolling mechanism.
- In yet other preferred forms, the first portion may be identical to the second portion.
- In yet other preferred forms, the container may be made of one of plastic and metal.
- In yet other preferred forms, the first restraining mechanism may be a belt strap.
- In yet other preferred forms, the emergency escape slide container may include a first handle on an outer surface of the first side wall.
- In yet other preferred forms, the emergency escape slide may include a locking mechanism that releasably secures the first portion to the second portion.
- In yet other preferred forms, the first storage space may have a length of about 43.75 inches (111.12 cm), a width of about 28.75 inches (73.025 cm), and a depth of about 11 inches (27.94 cm).
- In yet other preferred forms, the emergency escape slide container may include a raised ridge on an outer surface of the first end wall.
- In accordance with another exemplary aspect of the invention, a method of changing an emergency escape slide on an aircraft includes providing a replacement emergency escape slide within a container, the container having a first portion and a second portion removably attached to one another, the first portion and the second portion defining a first storage space and a second storage space, respectively. The first portion and the second portion are separated so that the replacement emergency escape slide remains attached to the first portion and at least partially disposed within the first storage space. The first portion is placed on a surface of an aircraft so that a rolling mechanism is disposed between the first portion and the surface. The first portion is moved on the surface to a predetermined location proximate an egress door of an aircraft. The first storage space is oriented to be adjacent to an emergency escape slide storage location on the aircraft. The emergency escape slide is separated from the first portion, and the emergency escape slide is secured to the emergency escape slide storage location.
- In other preferred forms, the method may include transporting the second portion to the predetermined location proximate the egress door. The second portion may be oriented so that the second storage space is adjacent the emergency escape slide storage location. An existing emergency escape slide may be released from the emergency escape slide storage location, and the existing emergency escape slide may be secured to the second portion so that the existing emergency escape slide is at least partially disposed within the second storage space.
- Objects, features, and advantages of the present invention will become apparent upon reading the following description in conjunction with the drawing figures, in which:
-
FIG. 1 is a perspective view of an aircraft emergency escape slide container; -
FIG. 2 is a top view of the aircraft emergency escape slide container ofFIG. 1 ; -
FIG. 3 is a front view of the aircraft emergency escape slide container ofFIG. 1 ; -
FIG. 4 is a side view of the aircraft emergency escape slide container ofFIG. 1 ; -

FIG. 6 is a top plan view of the upper portion of the aircraft emergency escape slide container ofFIG. 5 . - The emergency escape slide containers described herein advantageously allow an inflatable emergency escape slide to be stored and transported in a single container from a storage facility to an emergency escape slide storage location on aircraft. These emergency escape slide containers facilitate movement of the emergency escape slide by forklift or other transportation device from a storage location in a storage facility to an aircraft and then to a predetermined location in an aircraft. The emergency escape slide containers are robust and yet lightweight so that they are easily maneuverable within an aircraft by one or two maintenance personnel. Moreover, the emergency escape slide containers are sized to accommodate deflated and folded emergency escape slide in one portion and another deflated and folded emergency escape slide in another portion so that the container itself can be used to remove an existing emergency escape slide and to install a replacement emergency escape slide on an aircraft. The emergency escape slide containers also reduce on-the-job injuries because the emergency escape slide does not need to be removed from the container before transporting the emergency escape slide within an aircraft.

In some aircraft, the emergency escape slide storage location is attached to (or otherwise proximate or adjacent to) an egress door. Thefirst portion 12 may be oriented so that thefirst storage space 20 faces the emergency escape slide storage location. An existing emergency escape slide may then be released from the emergency escape slide storage location and moved into thefirst storage space 20 of thefirst portion 12. Once located in thefirst storage space 20 the emergency escape slide may be secured to within thefirst storage space 20 by thefirst securing mechanism 22 and/or by thesecond securing mechanism 23. After the existing emergency escape slide is secured within thefirst storage space 20, thefirst portion 12 may be reoriented so that thefirst rolling mechanism 24 is again resting on the floor of the aircraft cabin, and maintenance personnel may then roll thefirst portion 12 with the existing emergency escape slide to a door of the aircraft were thefirst portion 12 and the existing emergency escape slide may be then removed from the aircraft. - Once the existing emergency escape slide is removed from the aircraft, the
second portion 14 with a replacement emergency escape slide secured in asecond storage space 120 may be moved through the aircraft door and the aircraft cabin. Once located in the aircraft cabin, thesecond portion 14 may be oriented so that thesecond rolling mechanism 124 is located on the floor of the aircraft cabin. Thesecond portion 14 may then easily be rolled along the floor of the aircraft cabin, and down an aisle of the aircraft if needed, until thesecond portion 14 arrives in a predetermined location proximate the emergency escape slide storage location. - Once arriving at the predetermined location proximate the emergency escape slide storage location, the
second portion 14 may be oriented so that thesecond storage space 120 faces the emergency escape slide storage location. Thereafter, the replacement emergency escape slide may be released from thesecond portion 14 and moved into the emergency escape slide storage location. Once replacement emergency escape slide is secured in the emergency escape slide storage location,second portion 14 may be oriented so that thesecond rolling mechanism 124 is located proximate the floor the cabin. Thesecond portion 14 may then be rolled along the cabin floor to an exit of the aircraft. After removing thesecond portion 14 from the aircraft, thesecond portion 14 may be joined to thefirst portion 12 and releasably secured to thefirst portion 12 with the lockingmechanisms first portion 12 and thesecond portion 14.
