<p>The table is for use by one person, seated in a chair. It has a table top in two sections joined by a hinge (3). The hinge pivots downwardly whilst the two table top sections tilt towards each other between two fixed, horizontal, parallel supports (4,5). One only of the two sections (1,2) can slide at right angles to its support. The two sections, when horizontal, can slide parallel to their supports over a horizontal crosspiece.</p> |
