<p>Based on a cylindrical tube (1), of those typically used as legs, provided on its top end with means of attachment (2) to any type of conventional foundation box spring, upholstered board or other support base for a mattress, said tube (1) is open on its bottom and connected to a lower corner plate (3) through which the leg as a whole rests on the floor, by an interposed helical spring (5), which on its top is attached to tube (1) while on its bottom is attached to corner plate (6), so that said helical spring (4), which maintains the elements which it connects at a substantial separation, comprises a shock absorbing device which provides the leg with the ability to axially retract under the load supported by the bed. <IMAGE></p> |
