<p>A set of curtain rings has each ring (3) designed so that when assembled on their rail (2), they do not slope at different angles, but are all kept at right angles to the rail. Each ring has a block (6) which fits into a correspondingly shaped groove (7) along the rail. Each block is T shaped, with the head (6) of the T parallel to the centre line of the rail when inserted in the slot. Projecting downwards from this head is a lug (8) with a hole (9) through it, so that a card can be attached to all the blocks, the card being housed inside the slot. In an alternative design, the slot itself is also T shaped, and the block has side extensions to locate in the enlarged parts of the groove.</p> |
