Patent Application
20110253837
The invention relates to a pivot bin assembly. In particular, the invention is contemplated for use with overhead storage bins on passenger aircraft.
Commercial passenger aircraft generally include overhead luggage storage bins mounted from the ceiling of the aircraft over the passenger seats. These bins are designed to accommodate the size, shape, and weight of passenger carry-on luggage. One type of overhead storage, the overhead pivot bin features a bin that pivots open from the ceiling of the aircraft. To support the weight of passenger luggage and to meet safety certifications, the fundamental latch design of the pivot bin has been standardized as a two-point latch system, where the latches/hooks are located at the ends of the bin since the pivot bin design inception. The two ends latch point design transmits downward forces in the pivot bin directly to the structural bulkhead panels of the pivot bin housing. This methodology has long been proven to qualify the Overhead Pivot Bin structure for the FAR25 certification stress and dynamic crash requirements.
As shown in
In
Although the two-latch point design allows the downward forces from the bin to be spread out across the pivot bin housing 12, the usage of a linkage to actuate the two latches 34 creates added complexity and weight. Many specially configured actuating mechanisms and latches have been designed to implement a two-point latching system. A single or center point latching pivot bin would not need an actuating linkage mechanism as there is only one latch to be operated by the latch handle, thereby reducing the overall complexity, weight, and cost of the pivot bin by eliminating the need for two latches, two strikers, two transmission tubes and protective covers for the mechanism and tubes. Also, the striker and latch can be reversed.
Other overhead storage bin assemblies are well known in the art. For example, see U.S. Pat. No. 4,637,642 issued on Jan. 20, 1987 and U.S. Pat. No. 5,567,028 issued on Oct. 22, 1996, the entireties of which are hereby incorporated by reference.
In accordance with a first aspect of the present invention, there is provided a bin assembly that includes a bin housing and a bin that is movable between an open and a closed position within the bin housing. The bin housing includes a forward bulkhead panel, aft bulkhead panel and an aft housing panel that includes a rigid valence panel having one of a latch striker or a latch assembly secured thereto. The rigid valence panel has opposite ends that are secured to the forward and aft bulkhead panels. The bin includes an aft wall, a forward wall, a bin bottom and the other of a latch striker or a latch assembly secured to the bin bottom, thereby defining a latching location. A downward load in the bin is distributed from the latching location, along the rigid valence panel and to the aft and forward bulkhead panels.
In a preferred embodiment the latching location is located at approximately the center point between the aft wall and the forward wall of the bin and the rigid valence panel includes a front portion, a bottom portion and a rear portion that together define a valence panel interior for receiving lighting and latch assembly or the latch striker extend downwardly from the bottom portion of the rigid valence panel.
In accordance with another aspect of the present invention, there is provided a method that includes the steps of providing a bin assembly that includes a bin housing having a rigid valence panel for receiving lighting therein and a bin that is movable between an open and a closed position within the bin housing, moving the bin to the closed position, and latching the bin to the rigid valence panel.
In accordance with another aspect of the present invention, there is provided a pivot bin assembly that includes a pivot bin housing and first and second bins that are pivotable between opened and a closed positions within the pivot bin housing. The pivot bin housing includes an aft housing panel, a forward bulkhead panel, an aft bulkhead panel and a middle bulkhead panel. The aft housing panel includes a rigid valence panel that has opposite ends that are secured to the forward and aft bulkhead panels and the middle bulkhead panel is secured to the rigid valence panel. The rigid valence panel includes first and second latch assemblies that each have at least one hook extending downwardly therefrom. The first pivot bin is positioned between the forward and middle bulkhead panels and the second pivot bin is positioned between the middle and aft bulkhead panels. The first and second pivot bins each include an aft wall, a forward wall, a bin bottom and a latch striker secured to the bin bottom, thereby defining first and second latching locations. When the first and second pivot bins are in the closed position, downward loads in the first and second pivot bins are distributed from the first and second latching locations, along the rigid valence panel and to the aft, middle and forward bulkhead panels.
In a preferred embodiment, the rigid valence panel and the aft housing panel are formed as a unit by a molding process and the rigid valence panel includes a front portion, a bottom portion and a rear portion that together define a valence panel interior for receiving lighting. The hooks of the first and second latch assemblies extend downwardly from the bottom portion of the rigid valence panel. In another preferred embodiment, the first latching location is located at approximately the center point between the aft wall and the forward wall of the first pivot bin and the second latching location is located at approximately the center point between the aft wall and the forward wall of the second bin.

Referring now to the drawings, wherein the showings are for purposes of illustrating the present invention and not for purposes of limiting the same,
The single/center point latching pivot bin assembly 100 includes a pivot bin housing 112 that has a forward bulkhead panel 114, aft bulkhead panel 116, an aft housing panel 118 and a rigid valence panel 140 that extends between the forward and aft bulkhead panels 114 and 116. As shown in
As is best shown in
To close the bin 126, the hook or hooks 135 are secured on the latch striker 120 as is readily understood by one of ordinary skill in the art. The latch handle 130, latch mechanism 134, hooks 135 and other components (e.g., spring(s)) for securing the pivot bin 126 to the pivot bin housing 112 via the latch striker 120 are referred to herein together as the latch assembly. In a preferred embodiment, the latch assembly includes two hooks 135. This provides redundancy in case one of the hooks 135 fails. However, this is not a limitation on the present invention, and a single hook or more than two hooks can be used. If two or more hooks are used they are operated by the same latching mechanism and are located near center point of the pivot bin/pivot bin housing. The point or area in which the one or more hooks are latched to the striker is referred to herein as the latching location.
It will be appreciated by those skilled in the art that any latch assembly is within the scope of the present invention. For example, and latch assembly that includes a handle or lever that when actuated disengages a latch/hook from a striker to open the pivot bin is within the scope of the present invention.
It will be understood that the components of the pivot bin assembly 100 for pivoting the bin 126 open and closed (e.g., pivot mechanism 142,) are the same as the prior art pivot bin assembly 10 described above. Therefore, a discussion of these components will be omitted.
The pivot bin housing 112 can be formed as a single unit, or separate components can be bonded to one another. In a preferred embodiment, the rigid valence panel 140 is manufactured as an integrated molded component of the aft housing panel 118. By molding the valence panel 140 into the aft housing panel 118, using, for example, a crush core molding process, a rigid and continuous panel is formed. In the embodiment shown in
The general U-shape of the rigid valence panel 140 allows lighting to be positioned in the valence panel interior, just like the decorative valence panel of the prior art. However, the U-shape and integration of the rigid valence panel 140 with the aft housing panel 118 provides the structural capability of the rigid valence panel 140 to transfer the cargo load to the aircraft frame. This is achieved by latching the hooks 135, which extend from the bottom portion 140b of the rigid valence panel 140, to the striker 120, which is positioned on the bin bottom 131.
The pivot bin assembly 200 also includes a pivot bin 226 that has an aft wall 236, forward wall 238, bin bottom 231 and a center latch handle 230 that includes a latch mechanism 234 having a hook 235. The latch handle 230, latch mechanism 234, hook 235 and other components (e.g., spring(s)) for securing the pivot bin 226 to the pivot bin housing 212 via the latch striker 220 are referred to herein together as the latch assembly. It will be appreciated by those skilled in the art that any latch assembly is within the scope of the present invention. For example, any latch assembly that includes a handle or lever that when actuated disengages a latch/hook from a striker to open the pivot bin assembly is within the scope of the present invention.
It will be understood that the components of the pivot bin assembly 200 for pivoting the bin 226 open and closed (e.g., pivot mechanism 242) are the same as the prior art pivot bin assembly 10 described above. Therefore, a discussion of these components will be omitted.
The pivot bin housing 212 can be formed as a single unit, or separate components can be bonded to one another. In a preferred embodiment, the rigid valence panel 240 is manufactured as an integrated molded component of the aft housing panel 218. Therefore, the downward weight of the cargo in the bin 226 is transferred from the latching assembly 234 and striker 220, down the rigid valence panel 240 (see arrow A1 in
It will be understood that the bin does not have to be a pivot bin. It can be a moving bin or other type of articulating bin, as known in the prior art, as long as the bin is latched to the rigid valence panel of the upper bin housing.
