DESCRIPTION

[0018] The present disclosure relates to various embodiments of a baggage chute cushion configured to reduce damage to aircraft passenger baggage when the baggage is placed into a baggage chute adjacent to the aircraft and slid down to the ground level.

[0019] The terminology utilized herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As utilized herein, the singular forms a, an and the are intended to include the plural forms as well, unless the context clearly indicates otherwise. As utilized herein, the term and/or includes any and all combinations of one or more of the associated listed items.

[0020] It will be understood that, although the terms first, second, third, etc., may be utilized herein to describe one or more suitable elements, components, regions, and/or sections, these elements, components, regions, and/or sections should not be limited by these terms.

Accordingly, Applicant reserves the right to amend this specification, including the claims, to expressly recite any sub-range subsumed within the ranges expressly recited herein.

[0024] Example embodiments of the present disclosure will now be described with reference to the accompanying drawings. In the drawings, the same or similar reference numerals refer to the same or similar elements throughout. As utilized herein, the utilize of the term may, when describing embodiments of the present disclosure, refers to one or more embodiments of the present disclosure.

[0025] During aircraft boarding, when the overhead bin space becomes full, airlines routinely ask passengers to gate-check their carry-on items. These gate-checked items, along with items that cannot be stowed inside the overhead bins or under a seat, are temporarily held in the cabin area of the jet bridge before they are taken down to the cargo hold of the aircraft. FIG. 1 depicts an exterior view of a jet bridge 100. These gate-checked items may be carried through the jet bridge service door 110, and either hand-carried down the service stairs 120 or placed into the adjacent baggage chute 130 to slide down to the ground level 140. The baggage handling personnel on the ground level 140 will then retrieve these items to load into the aircraft's cargo compartment.

[0026] The jet bridge baggage chute 130 may have a semi-circular cross section that is directly next to the service stairs, leading diagonally from the cabin area of the jet bridge to the airport ramp ground. There is a stopping mechanism 132 at the bottom of the chute 130 to catch the items that are being slid down from atop.

[0027] Because of the steep slope of the baggage chute 130, the sliding items pick up great speed and momentum, especially because the end of the jet bridge 100 is often approximately 20 feet above the ground level 140. The high momentum of the heavy baggage leads to a high risk of damage to these items when they meet the stopping mechanism 132.

[0028] Aspects of embodiments of the present disclosure relate to a baggage chute cushion 150 placed on top of the chute stopping mechanism 132 to safely absorb the kinetic energy gained by the baggage as it slides down the chute. In the embodiment shown in FIG. 1, the baggage chute 130 has a semi-circular cross section and therefore the baggage chute cushion 150 is shown as having a cylindrical shape to fit within the chute 130. For example, the diameter of the baggage chute cushion 150 may be slightly smaller than the diameter of the semi-circular cross section of the chute 130.

[0029] While FIG. 1 shows a baggage chute 130 having a semi-circular cross section, other baggage chutes may have different cross-sectional shapes and cushions according to embodiments of the present disclosure may have corresponding shapes. For example, in the case of baggage chutes with rectangular or trapezoidal cross-sectional shapes, a baggage chute cushion 150 according to embodiments of the present disclosure may have matching shapes or other shapes that are suitable for the end of the baggage chute. Accordingly, in one or more embodiments, the cross-sectional shape of the baggage chute cushion 150 may correspond (or substantially correspond) to the cross-sectional shape of the chute 130. In one or more embodiments, the cross-sectional shape of the baggage chute cushion 150 does not correspond to the cross-sectional shape of the chute 130, such as where a cushion having a rectangular cross-sectional shape is used in a baggage chute with a trapezoidal cross-sectional shape.

[0030] The outer casing 151 of the baggage chute cushion 150 is made of a rip-resistant material such as a ripstop fabric. The outer casing 151 defines an interior space (e.g., a chamber or compartment) that is at least partially filled with at least two different layers of foam, an upper layer 152 and a lower layer 153. The upper layer 152 is at least partially filled with loose pieces of foam blocks 154, and the lower layer 153 is a singular foam disc 155. In the example shown in FIG. 1, the upper layer 152 is about (approximately) 3.5 inches thick, and the lower layer 153 is about (approximately) 10 inches thick, although the present disclosure is not limited thereto. Upon contact of an item sliding down the chute, the upper layer 152 of individual foam blocks 154 will compress and allow space between the blocks 154 to absorb and disperse the impact energy. The foam disc 155 of the lower layer 153, which is underneath the foam blocks 154 of the upper layer 152, serves as a structure to hold the loose foam blocks 154 in place, and to absorb the residual impact energy not absorbed by the upper layer 152.

[0031] The foam blocks 154 and the foam disc 155 each include an impact absorbing material. The impact absorbing material may be resilient (i.e., plastically deformable) such that the impact absorbing material is configured to compress during impact of the baggage and to return to its initial form (or substantially its initial form) after the baggage is removed. That is, upon contact of an item sliding down the chute, the cushion is compressed to absorb the impact force. When the items are removed from the chute, the cushion expands back to its original shape (or substantially back to its original shape) and to provide the same (or substantially the same) impact absorption functionality for the next baggage item.

[0032] The outer case 151 of the baggage chute cushion 150 includes a top surface 156 (e.g., an upper circular portion) and a sidewall 157 (e.g., a cylindrical sidewall) extended down from an outer periphery 158 (e.g., a circumferential edge) of the top surface 156. In some embodiments, the baggage chute cushion 150 includes built-in strapping mechanisms 159, which allows it to be secured to the body of the baggage chute 130. The built-in strapping mechanisms 159 may include a plurality of strap segments 160 stitched into the sidewall 157 of the rip-resistant fabric of the outer casing 151. The strap segments 160 may be provided in sets of two or more around the circumference of the sidewall (shown as an example in the figures as sets of three strap segments). Each of the strap segments 160 define a channel or tunnel 161 extending lengthwise along the strap segment 160 and circumferentially along a portion of the sidewall 157. The channels 161 are configured to receive an attachment mechanism securing the baggage chute cushion 150 to the chute 130. For instance, in one or more embodiments, straps, rope, or other attachment mechanisms may be looped through the channels 161 in the strap segments 160 on the sidewall 157 of the outer case 151 (which is formed of the rip-resistant material) and then secured to the structure of the chute 130. Additionally, in the illustrated embodiment, a lower edge portion of the sidewall 157 includes a plurality of openings 162 (e.g., holes) and a plurality of grommets 163 in the plurality of openings 162. In one or more embodiments, the baggage chute cushion 150 may also include a separate lower cover member (e.g., a flat circular piece of rip-resistant fabric) configured to cover an open lower end of the outer case 151. The lower cover member may be secured to the outer case 151 by lacing a rope or other tensile member through the grommets 163 and then tightening the tensile member.

[0033] FIGS. 2A, 2B, 2C, and 2D depict steps for constructing a baggage chute cushion according to one embodiment of the present disclosure. While FIGS. 2A, 2B, 2C, and 2D depict a technique for assembling a cylindrical baggage chute cushion having a height of approximately 14 inches and a diameter of approximately 20 inches, embodiments of the present disclosure are not limited thereto and those skilled in the art would understand from the disclosure herein how to construct a baggage chute cushion according to other embodiments of the present disclosure to be suitable for baggage chutes of various shapes and sizes. In the illustrated embodiment, a lower edge portion of the sidewall includes a plurality of openings (e.g., holes) and a plurality of grommets in the plurality of openings. During assembly, the inner resilient impact absorbing members (e.g., the loose foam blocks and foam disc) are inserted into the outer casing, a separate lower cover member (e.g., a flat circular piece of rip-resistant fabric) is placed to cover a lower end of the inner resilient impact absorbing member, the lower edge portion of the sidewall including the grommets is folded or tucked underneath the bottom of the inner resilient impact absorbing member, and then a rope or other tensile member is laced through the grommets and tightened to secure the outer casing and the lower cover member to the inner resilient impact absorbing member.
