Tray tables principally for use in passenger vehicles
Tray tables adapted to support, among other things, certain portable electronic devices while in use are detailed. The tables may include multiple sections designed to move relative to horizontal bases. When not needed, the moveable sections may be stowed in recesses in upper surfaces of the bases.
This application claims the benefit of U.S. Provisional Patent Application No. 60/786,123 filed on Mar. 27, 2006, the contents of which are incorporated herein by reference.
FIELD OF THE INVENTIONThis invention relates to tables and more particularly, although not necessarily exclusively, to tray tables commonly used in aircraft, trains, and other passenger transport vehicles.
BACKGROUND OF THE INVENTIONU.S. Pat. No. 4,526,421 to Brennan, et al. illustrates a conventional tray table intended for use by commercial aircraft passengers. The table is of unitary construction and adapted to pivot along an edge remote from the passenger with which it is associated. When deployed, the table is pivoted to a substantially horizontal position so it may serve as a platform for a food tray or other object. The table additionally is connected to moveable arms extending rearward from a seat positioned in front of the passenger. When not in use, the table may be pivoted to a substantially vertical position for stowage in a space present in the back of that seat.
U.S. Pat. No. 6,761,398 to Bentley, et al. discloses additional tray tables stowable within or adjacent to seat backs. Although some of the tray tables of the Bentley '398 patent are unitary structures like those of the Brennan patent, others are not. Some tables, for example, have a second pivot axis intermediate (between) the passenger and the first pivot axis at the moveable arms. These types of tables are typically called “bi-fold” tables to reflect that they are typically pivoted twice for deployment or storage.
Detailed in U.S. Pat. No. 6,237,994 to Bentley, et al. are various tray table assemblies adapted for stowage within arm rests of passenger seats. Some of the table assemblies of the Bentley '994 patent are adjustable vertically while remaining substantially horizontal platforms. Others of the assemblies include an upper section that itself may pivot relative to a base to a non-horizontal position. As noted in the Bentley '994 patent, this upper section “may thus function not just as the horizontal platform of conventional tables, but also as a non-horizontal rest for books, magazines, computers, or other objects.” See Bentley '994, col. 5, 11. 32-35.
SUMMARY OF THE INVENTIONThe present invention provides improvements to existing tray table designs, including but not limited to those of the Bentley '994 patent. Included as part of the innovative tables are multiple sections designed to pivot, or otherwise move, relative to horizontal bases. These moveable sections cooperate to support such things as laptop computers, portable digital video disc (DVD) players, and books for use, with monitor screens of computers and DVD players, for example, being easily viewed by corresponding passengers. The moveable sections additionally may be designed to fit into a recess present on the upper surface of the horizontal bases of the tables.
Preferred versions of the invention include a main object support and a stop positionable substantially perpendicular thereto. Such versions also may include a brace for the main object support and a secondary, or ancillary, object support. Advantageously each of these pieces may move relative to a horizontal base, although those skilled in the relevant art will recognize that movement of all such pieces might not always be necessary.
Moveable sections of the invention may be made of plastic or other material as appropriate or desired. Preferably the materials are lightweight (particularly if used on-board aircraft) so as not to increase meaningfully the weight of any vehicle in which they are deployed. They nonetheless are sufficiently strong and rigid to support certain portable electronic or other objects.
Alternate versions of the invention may include more or fewer moveable pieces than in preferred versions. Moreover, moveable pieces need not necessarily be stowed in a recess in the upper surface of a horizontal base. Yet additionally, in some embodiments of the invention, a first portion of the base itself may pivot at an angle to a second portion of the base so as to form part of the main object support.
It thus is an optional, non-exclusive object of the present invention to provide innovative tray tables.
It is also an optional, non-exclusive object of the present invention to provide tray tables for use in passenger vehicles.
It is another optional, non-exclusive object of the present invention to provide tray tables adapted for use with portable electronic equipment, books, or other objects.
It is a further optional, non-exclusive object of the present invention to provide tray tables capable of supporting laptop computers and portable DVD players so that their screens are readily viewable by passengers.
It is an additional optional, non-exclusive object of the present invention to provide tray tables having one or more pieces moveable relative to a horizontal base.
It is, moreover, an optional, non-exclusive object of the present invention to provide tray tables in which moveable pieces may be stowed in a recess in a horizontal base.
It is yet another optional, non-exclusive object of the present invention to provide tray tables having some or all of a horizontal base, a main object support, a stop, a brace, and a secondary object support.
Other objects, features, and advantages of the present invention will be apparent to those skilled in the relevant art with reference to the remaining text and drawings of this application.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 6A-C depict a first alternate tray table of the present invention.
FIGS. 7A-B illustrate a second alternate tray table of the present invention.
Detailed in
Consistent with its traditional uses, table 14 is designed to function as a stable surface on which to place food trays or similar items. Accordingly, table 14 comprises platform or base 38 which, when deployed, is positioned substantially horizontally with its upper face 42 being flat (or substantially so). This configuration is shown in
Base 38 may comprise a unitary structure. Alternatively, it may have a bi-fold structure as appears in
Also included as part of base 38 is recess 58. In a bi-fold base design, recess 58 preferably is present in upper surface 42A of base section 38A. In any configuration, however, recess preferably is present in a portion of base 38 adjacent proximal edge 50.
In the version of assembly 10 illustrated in
Recess 58 may be defined, in part, by proximal wall 82 and distal wall 86. Present in or adjacent proximal wall 82 is an axle or other structure 88 to which both main object support 66 and stop 70 may be connected. Brace 74 and secondary support 78 are connected to main support 66 and adapted to move relative to it.
Secondary support 78 additionally may comprise cut-out 90 adjacent distal wall 86 when component assembly 62 is fitted into recess 58. Cut-out 90 may function as a finger hole for initiating movement of the component assembly 62 when it is fitted into recess 58. A passenger may grasp cut-out 90 with a finger and pull secondary support 78 toward him or her, thereby causing at least interconnected secondary support 78, main support 66, and brace 74 to protrude above upper surface 42A.
As such pulling occurs, hinges 94 connecting top portion 98 of brace 74 to main support 66 allow brace 74 to swing outward such that its bottom portion 102 contacts distal wall 86 of recess 58. Distal wall 86 thus serves to anchor brace 74 against further outward swinging, causing component assembly to assume the configuration depicted in
Thereafter, stop 70 may be pivoted about structure 88 so that it no longer lies in the same plane as main support 66. Indeed, as shown in
If the object to be supported is taller than main support 66, secondary support 78 may be deployed. As illustrated in
FIGS. 7A-B show an analogous pair of main supports 300A and 300B as part of assembly 10″. Such supports 300A and 300B may, however, include pull-ups 304A and 304B to provide greater support for tall objects or to place them at angles relative to base 308 greater than those typically provided by assemblies 10 and 10′.
The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention. Incorporated herein by this reference are the entire contents of each of the Brennan, Bentley '398, and Bentley '994 patents.
