DESCRIPTION:
BRIEF SUMMARY
The invention relates to a table to be attached at the rear of a chair back, where the table comprises two table surfaces being attached to the back of the chair in such a manner that they can be swung out from an erect position parallel to the chair back to an operative position, in which position the table surfaces are parallel to each other at different horizontal levels.
Tables of this sort are especially used in connection with seats, where the person sitting must be able to put objects or place e.g. food and beverages on the tables.
Chairs with such tables are especially mounted in flight cabins, busses, train carriages, waiting rooms and similar places where maximum comfort is required, and where it is desirable that the tables may be collapsed when not used in order that passage may take place unobstructedly between rows of chairs where the chairs stand close to each other in rows.
Tables with two table surfaces are e.g. known from the specification of U.S. Pat. No. 2,973,028 which concerns a table device which can be attached rearwardly projecting from the back of a chair. The tables are hinged to a floor bracket in such a manner that the upper table must be swung out and up before the lower table can be swung out and down. This limits the number of choices in that it is only possible to have either the upper table or having both tables together tilted down at the same time.
Morover, a table is known with only one single table surface which can be swung out and down from a folded-up position, where the table surface by means of a catch is held firmly to the back of the chair. This table surface is especially used in passenger cabins where it is required that the table is low-weight and takes up only little space in its folded-up position.
However, there is only one single table surface which either provides too much table space if for instance only a cup is to be placed on the table, or too little table space where a whole meal with drinks is served on a tray. Moreover, it is impossible to pass through the rows of chairs when such a table is tilted down, which is a considerable drawback.
It is the object of the invention to overcome these drawbacks and to obtain advantages, and this is achieved by a table, where the lower table at the rear part of the side edges is hinged to table legs being mounted at the lower part of the chair back in such a manner that the table legs may be swung out, and in that the upper table surface at the rear part of the side edges is hinged to a distance piece which is also hinged to the table legs.
This first of all provides the possibility of choosing to unfold the lower table surface only or to unfold the lower as well as the upper table surfaces simultaneously. When the lower table surface is largest, and the upper a narrower plate, a particularly advantageous construction is achieved which fully meets the requirements for a large as well as a small table for a tray, plates, and food, and for glasses, cups and beverages, respectively. This means that a better distribution of the objects on the tables is obtained, and consequently a more aesthetic and practical separation between the various objects.
Add to this that this table device does not take up more room than does the known single table, whereby is obtained a much wider choice and utility value.
By connecting the two table sections with two rails, as referred to in claim 2, a construction is achieved which is expedient in terms of low weight and little space requirements.
By, as referred to in claim 3, designing the distance piece as a plate, this plate can by the single plate position form part of this, and therefore it will not extend beyond the table surface thereby being inconvenient to the user.
By, as referred to in claim 4, providing the lower table with a further shelf at its outer part, a shelf may in the erect position of the table surfaces be tilted down, which makes it possible to place a cup, glass or the like on the shelf which will only take up as much space between the rows of chairs as the siz
