Fold-away bunk bed

Abstract

A fold-away bunk bed including a supporting framework to which two bedsprings, an upper bedspring and a lower bedspring, are hinged; the bedsprings have at least two working positions: an open position, in which the bedsprings are in a horizontal position, and a closed position, in which they are in a vertical position and are substantially included within the framework. Each one of the bedsprings is hinged to the framework by an independent articulated structure that is contained in a lateral shoulder of the framework.

1 . A fold-away bunk bed comprising a supporting framework having at least two shoulders to which two bedsprings, an upper bedspring and a lower bedspring, are hinged; each of said bedsprings having at least two working positions: an open position, in which said bedsprings are in a horizontal position, and a closed position, in which said bedsprings are in a vertical position and are substantially comprised within said framework; wherein each of said bedsprings is hinged to said framework by means of an independent articulated structure that is contained in said lateral shoulders of said framework. 
     
     
         2 . The bunk bed according to  claim 1 , wherein each of said bedsprings comprises a tubular frame hinged to said articulated structure by means of a rotation pivot; said rotation pivot engaging a seat provided in a plate that is integral with said shoulder of said framework. 
     
     
         3 . The bunk bed according to  claim 2 , wherein said articulated structure comprises a lever that has an end hinged at said pivot and a free end hinged to a first end of an elastic member; said elastic member comprising a second end that is pivoted to said plate of said articulated structure. 
     
     
         4 . The bunk bed according to  claim 3 , wherein said frame has a rear bar in which two locking pins are arranged, one for each side; on one side, a locking pin being actuated by an actuation lever, in contrast with a contrast spring; said actuation lever being inserted substantially inside said tubular frame and having a grip member that can be accessed by virtue of a lateral opening of said tubular frame; by pulling said grip member, said actuation lever extracts said pin from a locking seat of said plate and, by virtue of a cable and pulley system, extracts the other pin as well, leaving said frame free to rotate about said rotation pivot. 
     
     
         5 . The bunk bed according to  claim 4 , wherein said articulated structure of said bedspring comprises at least two locking positions of said pin, which correspond respectively to said open position of said bed and to said closed position of said bed. 
     
     
         6 . The bunk bed according to  claim 4 , wherein said articulated structure of said bedspring comprises at least three positions for locking said pin, which correspond respectively to said open position of said bed, to said closed position of said bed and to a partially open position, in which said upper bedspring is inclined downward at approximately 45°. 
     
     
         7 . The bunk bed according to  claim 4 , wherein it comprises a ladder; in said open position of the bed, said ladder is first engaged with said frame of said lower bedspring and then with said frame of said upper bedspring. 
     
     
         8 . The bunk bed according to  claim 7 , wherein said ladder is locked in an operating position by means of two knobs which arm themselves during the engagement step and must be pulled in order to release the ladder and remove it. 
     
     
         9 . The bunk bed according to  claim 4 , wherein it comprises protective barriers for each bedspring: an upper protective barrier and a lower protective barrier. 
     
     
         10 . The bunk bed according to  claim 9 , wherein said barrier comprises a first part, which is fixed to said frame of said bedspring, and a second part, which is articulated with respect to said first part by virtue of gears; said parts of said barrier are folded, when said bed is in said closed position, and arm themselves, during opening, locking themselves in a substantially vertical position, with a slight inclination, in said open position of said bed; during closure, said barrier is released by acting on a release button and, in said closed position, said second part rests on a mattress associated with said bedspring. 
     
     
         11 . The bunk bed according to  claim 1 , wherein it comprises at least one foot associated with said lower bedspring; said foot comprising a foot body hinged to said bedspring by means of a ball bearing and having a spring locking means adapted to lock said foot in a vertical position; said foot body having longitudinal seats for a slider which is movable with respect to said foot body; an adjustable member being adjustably fastened to said slider by means of a bolt which clamps said adjustable member against dented regions of said slider; said slider sliding into the foot body and locking therein by the action of the weight of said lower bedspring on said foot.
