The present invention provides a covered sliding operator that is particular useful for in adjustable tables (1) and similar pieces of furniture. The covered, sliding operator a body (3); a slot (6) formed in the body (3) having a first end and a second end and a length extending from the first end to the second end; a spindle (5) extending through the slot (6) and mounted to be slidable along the length of the slot (6); and a generally oval cover (10) rotatably mounted on the spindle (5). Wherein, the body (3) has a first impinging wall (16) formed on an inner side of the slot (6) and spaced a distance from the first end of the slot and a second impinging wall (17) formed on an inner side of the slot (6) and spaced a distance from the second end of the slot (6), The cover (10) is shaped such that: when the spindle (5) is central in the slot (6) a width of the cover (10) completely covers the slot (6), from the first end to the second; moving the spindle (5) towards the first end of the slot (6) moves the cover against the first impinging wall (16) and causes it to rotate in a first direction such that the slot (6) remains- completely covered by the cover (10); and moving the spindle (5) towards the second end of the slot (6) moves the cover (10) against the second, impinging wall (17) and causes it to rotate in a second direction such that the slot (6) remains completely covered by the cover (10). in this manner the cover (10) of the covered sliding operator ensures that the slot (6) is covered at all times, thereby preventing anything being inserted into, or through, the slot (6). |
