TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
The present invention relates generally to a deployable dining table associated with an aircraft passenger seat, and more particularly, to a dining table hinged for compound movement between a stowed position beneath a fixed vanity table and a deployed ergonomic position for dining or other use.
Airlines offering business and premium seating classes often incorporate passenger suites into their cabin layouts. Suites are typically defined by privacy walls and include lie-flat adjustable seats, vanities, desks, video monitors, tables, etc. In certain configurations, vanities and desks can take the form of static structures positioned forward of the seat. While forward spacing facilitates seat ingress, egress and full horizontal adjustability, it makes it impractical and uncomfortable to use these static structures for working and dining purposes. Therefore, additional tables that deploy closer to the seat are necessary.
Tray tables have historically been deployable from one of an armrest positioned alongside the seat, a monument laterally adjacent the seat, or from beneath a desk positioned forward of the seat. In each of the foregoing configurations it is necessary to move the table between a stowed position and a deployed use position. Armrest and monument deployable tables require complex hinges in order to change the orientation of the table for stowing and use, e.g., from vertical to horizontal. Tables that deploy from beneath a forward static structure require linear movement forward and aft. Because most vanities, desks and like forward static structures have a different height than the ergonomic height of a dining table, complex mechanisms are necessary to deploy the table towards the user and lower the table to the proper ergonomic height.
Therefore, to overcome the disadvantages of prior art deployable tables and complex hinge mechanisms, what is needed is a mechanism that provides compound movement for a forward positioned deployable dining table.
BRIEF SUMMARY OF THE INVENTION
It is an object of the invention to provide a table associated with a seat that is movable between a stowed position and an ergonomic use position.
It is another object of the invention to provide a mechanism that imparts vertical and horizontal translation of a table, thus providing a difference in the vertical and horizontal positions in stowed and deployed positions of the table.
It is yet another object of the invention to provide a table that deploys from beneath a static structure positioned forward of a seat.
It is yet another object of the invention to provide a table that stows apart from a passenger seat to permit seat ingress, egress and full adjustability, and deploys to an ergonomic position close to the seat for dining or other use.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described more fully hereinafter with reference to the accompanying drawings in which exemplary embodiments of the invention are shown. However, the invention may be embodied in many different forms and should not be construed as limited to the representative embodiments set forth herein. The exemplary embodiments are provided so that this disclosure will be both thorough and complete, and will fully convey the scope of the invention and enable one of ordinary skill in the art to make, use and practice the invention. Like reference numbers refer to like elements throughout the various drawings.
FIG. 1 shows an aircraft passenger suite 20 according to an embodiment of the invention. Suite 20 can be of the type found in a premium seating class of a cabin layout, which may include a plurality of like suites and different suites in a nested arrangement to maximize seating density while providing privacy and a feeling of open space. Suite 20 as shown generally includes an adjustable passenger seat 22 and a static structure 24 positioned directly forward of the seat 22. As shown, the static structure 24 is a horizontal desk or vanity positioned at a vertical height higher than what would be considered an ergonomic position for dining. A video monitor 26 is positioned above the static structure 24 and directly forward of the seat 22 for optimal viewing angle.
A deployable table assembly 28 according to an embodiment of the invention deploys from beneath the static structure 24. A table 30 of the table assembly 28 is configured to move, by way of combined horizontal translation and vertical translation, between a stowed position in which the table 30 is entirely underneath the static structure 24, and deployed position forward of and vertically lower than when in the stowed position. In other words, the table 30 stows underneath the static structure 24 when not being used, and deploys forward and lower for use. Thus, the table 30 is configured to fore, aft and vertical motion. The compound movement deploys the table 30 close to the seat 22 at an ergonomic position for dining. As shown, the underside of the desk may include a recess for receiving the table 30 therein when the table 30 is stowed.
FIGS. 2-4 show the deployable table assembly 28 separate from the static structure. While conventional dining tables may be capable of linear movement forward and aft, the present table 30 is hinged for compound movement, i.e., simultaneous movement forward/aft and up/down along an elliptical path. The assembly 28 generally includes the table 30, first and second non-parallel static rails 32, 34, and first and second hinges 36, 38 attaching the table 30 to the first and second non-parallel static rails 32, 34. The first and second hinges 36, 38 are configured to travel along the first and second non-parallel static rails 32, 34 by way of first and second carriages 40, 42 to selectively move the table 30 between the stowed and deployed positions, wherein the table 30 when in the deployed position is forward of and vertically lower than the table 30 when in the stowed position. Reference numeral 44 indicates the stowed configuration of the table 30. Reference numeral 46 indicates the deployed configuration of the table 30.
The first and second static rails 32, 34, first and second hinges 36, 38, and first and second carriages 40,42 are all provided in pairs (i.e., right and left members), which cooperate to guide and support the left and right sides of the table 30. Each of the first and second hinges 36, 38 is attached at one end (i.e., the “lower” end) to one side of the table 30, and at the opposite end (i.e., the “upper” end) to its respective one of the carriages 40, 42. The carriages 40, 42 travel together along the length of the static rails 32, 34 forward and aft.
The first and second static rails 32, 34 are non-parallel, and specifically, converge in the direction of the stowed position and diverge in the direction of the deployed position. In this arrangement, movement of the table 30 in the forward direction, i.e., towards the seat 22 (see FIG. 1) causes the first and second hinges 36, 38 to rotate toward a vertical orientation, and movement of the table 30 in the aft direction, i.e., away from the seat 22, causes the first and second hinges 36, 38 to rotate toward a horizontal orientation. In a specific embodiment, the hinges 36, 38 can be vertical when the table 30 is fully deployed and horizontal when the table 30 is fully stowed, thus compact stowage conducive for aircraft.
As best shown in FIG. 3, the upper ends of the first and second hinges 36, 38 move inward, i.e., toward each other, as the table 30 travels in the direction of the stowed position indicated at 44, and move outward, i.e., apart from one another, as the table 30 travels in a direction of the deployed position indicated at 46. In other words, the first and second hinges 36, 38 fold inward as the table 30 is stowed and fold outward as the table 30 is deployed. Table movement can be manual or automated. The first and second non-parallel static rails 32, 34 are elongate linear rails adapted to attach to the underside of the static structure positioned forward of the seat.
FIG. 5 shows first and second stabilizing arms 48, 50 that prevent the table 30 from swaying laterally. The first and second stabilizing arms 48, 50 are synchronized to move inward in unison as the table 30 is stowed and outward in unison as the table 30 is deployed. One end of the first stabilizing arm 48 is pivotally attached to the first hinge 36, while the opposite end of the first stabilizing arm 48 is slidably attached at the back of the table 30, for example, attached to a first spring-biased stabilizing mechanism 52 in the back of the table. One end of the second stabilizing arm 50 is pivotally attached to the second hinge 38, while the opposite end of the second stabilizing arm is slidably attached at the back of the table 30, for example, attached to a second spring-biased stabilizing mechanism 54 in the back of the table.
The foregoing description provides embodiments of the invention by way of example only. It is envisioned that other embodiments may perform similar functions and/or achieve similar results. Any and all such equivalent embodiments and examples are within the scope of the present invention and are intended to be covered by the appended claims.
