Pull-down bed assembly

Abstract

A pull-down bed assembly including a movable frame which constitutes the bedspring and is pivoted to a fixed frame so as to define a closed vertical position, in which the movable frame is substantially in a vertical position, and an open horizontal position, for use as a bed, in which the movable frame is in the horizontal position; the assembly has a balancing system, which is adapted to control the movement of the movable frame with respect to the fixed frame. The balancing system is constituted by springs with a respective transmission mechanism, which are arranged within the fixed frame and the movable frame and are not visible from the outside both in the closed position and in the open position of the movable frame.

1 . A pull-down bed assembly, comprising a movable frame which constitutes the bedspring and is pivoted to a fixed frame so as to define a closed vertical position, in which said movable frame is substantially in a vertical position, and an open horizontal position, for use as a bed, in which said movable frame is in the horizontal position; further comprising a balancing system, which is adapted to control the motion of said movable frame with respect to said fixed frame and is constituted by one or more springs and by a respective transmission mechanism, which are arranged within said fixed frame and said movable frame and are not visible from the outside both in said closed vertical position and in said open horizontal position of said movable frame. 
     
     
         2 . The assembly according to  claim 1 , wherein said movable frame is pivoted to said fixed frame by means of a pair of mounting plates, which constitute said fixed frame together with connecting cross-members; each of said mounting plates comprises an upright having a seat for a rotation pivot which is integral with said movable frame; said rotation pivots allow a rotation of said movable frame about a rotation axis that passes through said pivots and is arranged at the front with respect to a rear cross-member of said movable frame. 
     
     
         3 . The assembly according to  claim 2 , wherein said balancing system includes a helical first spring and a helical second spring, the springs being integral with said fixed frame; each of said springs is connected to one side of the movable frame by means of a respective transmission mechanism; said first spring is arranged in a horizontal position and is extended transversely in said fixed frame parallel to said second spring; each one of said springs comprises a fixed end, which is associated with said fixed frame by means of an adjustment screw, and a movable end, which is connected to a first end of a respective cable; a second end of said cable is fixed to said movable frame; said second end of said cable is fixed to an arm which is integral with said rear cross-member of said movable frame; said cable is guided by means of two pulleys, one having a vertical axis and one having a horizontal axis. 
     
     
         4 . The assembly according to  claim 1  wherein said movable frame is covered by a panel, made of wood or other suitable material, and said fixed frame is covered at the front by a box-like body and at the rear by a headboard. 
     
     
         5 . The assembly according to  claim 4  wherein said box-like body is extended laterally beyond the lateral space occupation of said movable frame and constitutes bedside tables which are integrated in the assembly. 
     
     
         6 . The assembly according to  claim 1 , wherein said movable frame is pivoted to said fixed frame by means of pivots pivoted to a pair of uprights, which are associated with said fixed frame through a base member; said pivots allow the rotation of said movable frame about a rotation axis, which passes through said pivots; said pivots are arranged at a distance from a rear cross-member of said movable frame. 
     
     
         7 . The assembly according to  claim 6 , wherein said movable frame is constituted by said rear cross-member connected to a front cross-member by means of two side beams. 
     
     
         8 . The assembly according to  claim 7 , wherein said balancing system comprises a pair of springs; each of said springs is inserted in a respective one of said side beams and is connected to a respective transmission mechanism; each of said springs has a fixed end, connected to said movable frame, and a movable end, which is connected to a first end of a respective cable; a second end of said cable is fixed to the fixed frame; said second end of said cable is fixed to a bracket, which is fastened to said base member; said cable is guided by means of two pulleys: a fixed pulley and a movable pulley; said fixed pulley is fastened to said base member while said movable pulley is fastened at said movable frame. 
     
     
         9 . The assembly according to  claim 8 , wherein said movable frame is provided with a U-shaped feet bar having opposite ends pivoted to said movable frame; said opposite ends are connected to a motion control mechanism that moves said feet bar from a retracted position, when said movable frame is in said vertical position, to a working extended position, at right angle with said movable frame, when said movable frame is in said horizontal position, and from said extended position to said retracted position when said movable frame moves from said horizontal position to said vertical position. 
     
     
         10 . The assembly according to  claim 9 , wherein each of said opposite ends of said feet bar is provided with a gear wheel which engages a respective rack; said rack slides within a respective one of said side beams thus making the gear wheel rotate in order to move said feet bar from said working extended position to said retracted position, parallel to said frame; said rack is controlled by a lever system which is contained in said side beam of said movable frame and is connected to at least one of said uprights; said lever system causes said rack to slide when said movable frame is rotated about its pivots from said horizontal position to said vertical position and vice versa. 
     
     
         11 . The assembly according to  claim 9 , wherein, when said movable frame is in said vertical position, said feet bar is completely contained within said movable frame which is provided with a front cover and side covers that extend along the front and sides of said movable frame. 
     
     
         12 . The assembly according to  claim 11 , wherein said side covers also conceal from view said uprights when said movable frame is in said vertical position. 
     
     
         13 . The assembly according to  claim 1  wherein in said horizontal position of said movable frame said springs are under such a tension as to counterbalance the weight of said movable frame. 
     
     
         14 . The assembly according to  claim 1  wherein said assembly is self-supporting and is not fastened to any external support.
