Baby cribs

Abstract

A foldable baby crib comprising a flexible enclosure adapted to accommodate a baby, an upper frame for supporting the enclosure along its upper edge, and two support structures connected to the upper frame to hold the enclosure in a lifted position. The upper frame comprises two half-parts which are pivotally articulated to each other at two junction devices and are pivotally articulated each to a respective support structure. The support structures, which are initially spaced apart from each other, move toward each other as the crib is being closed, while the half-parts of the upper frame pivot relative to each other and to the support structures. The two junction devices of the upper frame are spaced apart from each other both in the open configuration and in the closed configuration of the crib at a substantially constant distance.

1 . A baby crib, comprising:
 an upper frame, which is configured to support an enclosure for receiving a baby, the upper frame comprising two half-parts that are pivotally articulated to each other at two junction devices,   two support structures, which are configured to hold the upper frame raised relative to a bearing surface, each support structure being pivotally articulated to a respective half-part of the upper frame,   
       wherein:
 the crib is adapted to switch between an open configuration in which the support structures are spaced apart and a closed configuration in which the support structures are close together, 
 the half-parts of the upper frame are configured to pivot relative and toward each other and to pivot toward their respective support structures during transition from the open configuration to the closed configuration, 
 
       wherein the distance between said junction devices remains substantially constant during the transition from the open configuration to the closed configuration. 
     
     
         2 . A crib as claimed in  claim 1 , wherein:
 in the open configuration the support structures are spaced apart in a longitudinal direction,   the support structures are pivotally connected to the respective half-parts of the upper frames at respective hinges, and   the half-parts of the upper frame are configured to move said hinges by translating them only in the longitudinal direction during the transition from the open configuration to the closed configuration.   
     
     
         3 . A crib as claimed in  claim 1 , wherein:
 each half-part of the upper frame comprises two end portions, said junction devices being disposed at the end portions of the half-parts, and   the two end portions of each half-part are fixed together at a constant distance.   
     
     
         4 . A crib as claimed in  claim 1 , wherein each support structure comprises two legs, the distance between the two legs of each support structure remaining substantially constant during the transition from the open configuration to the closed configuration. 
     
     
         5 . A crib as claimed in  claim 4 , wherein the two legs in each support structure are fixed together at a constant distance. 
     
     
         6 . A crib as claimed in  claim 5 , wherein each support structure comprises a transverse rod which extends between the two legs of the support structure, the transverse rod being fixed to the two legs. 
     
     
         7 . A crib as claimed in  claim 4 , wherein:
 each half-part of the upper frame comprises a rigid connecting rod having two ends, the two legs of each support structure being hinged to their respective half-part of the upper frame at the ends of the connecting rod.   
     
     
         8 . A crib as claimed in  claim 7 , wherein the angle of inclination between each leg and its respective connecting rod remains constant during the transition from the open configuration to the closed configuration. 
     
     
         9 . A crib as claimed in  claim 1 , wherein:
 each junction device of the upper frame comprises a first lock mechanism, which is configured to prevent the half-parts of the upper frame from pivoting relative to each other, and   the crib comprises a release actuator for each junction device, which is operable to release the first lock mechanism and allow transition to the closed configuration.   
     
     
         10 . A crib as claimed in  claim 9 , wherein:
 each half-part of the upper frame comprises a second lock mechanism which is configured to prevent the half-part from pivoting relative to its respective support structure, and   the release actuators of the junction devices are configured to simultaneously release the first lock mechanisms and the second lock mechanisms and thereby allow transition to the closed configuration.
