<p>Adjustable shelving comprises a shelf (10) on support posts (12) passing through corners thereof. The corners of the shelf have corner pieces (16) of plastics material therein that sit on collets (20). Each collet has an internal annular rib (22) that engages one of a series of circumferential grooves (14) of the support part 12. The weight of the shelf presses the corner piece downwards and that in turn squeezes the collet to secure its grip on the support post. Lifting the shelf releases the collets so that they may each be repositioned on another groove of the support posts, in order to set the shelf at a different height.</p> |
