Convertible double-decker bed

Abstract

Frequently there is a need to have a bed extended so as to provide for additional sleeping space. Typically a horizontal extension is provided that requires a larger floor space. Alternatively double-decker beds are used but these are cumbersome and less than attractive for every-day use. A bed comprised of two frames each having a mattress where the top frame lays over the bottom frame during normal usage is provided. When additional sleeping space is required the upper frame is raised vertically over the lower frame, creating a double-decker bed.

1 . A bed comprising:
 a first frame for placing a first mattress;   a second frame for placing a second mattress; and,   a mechanism enabling the vertical motion of said second frame from said first frame;   wherein said first frame and said second frame are positioned, by said mechanism, at a vertical distance from each other with a gap between them.   
   
   
       2 . The bed of  claim 1 , wherein said mechanism enables the positioning of said second frame from said first frame at a distance that enables the usage of the bed as a double-decker bed. 
   
   
       3 . The bed of  claim 1 , wherein said mechanism is at least one of: electrical, mechanical, and pneumatic. 
   
   
       4 . The bed of  claim 1 , further comprising:
 at least a safety latch.   
   
   
       5 . The bed of  claim 4 , wherein said safety latch secures said second frame position with respect to said first frame position. 
   
   
       6 . The bed of  claim 4 , wherein said safety latch is manually placed in its position. 
   
   
       7 . The bed of  claim 4 , wherein said safety latch is automatically placed in its position. 
   
   
       8 . The bed of  claim 1 , wherein said mechanism is further configured to enable vertical motion of said first frame. 
   
   
       9 . The bed of  claim 1 , further comprising at least one of: a pressure sensor for said first frame and a pressure sensor for said second frame. 
   
   
       10 . The bed of  claim 9 , wherein said pressure sensor is coupled to said mechanism. 
   
   
       11 . The bed of  claim 10 , when a pressure detected by said pressure sensor is above a threshold, said mechanism will not perform said vertical motion. 
   
   
       12 . A method for transforming a bed comprising a first frame and a second frame placed one on top of the other into a double-decker bed, comprising:
 causing a mechanism to vertically move said second frame of said bed from said first frame of said bad,   wherein said second frame is moved from said first frame at a distance that enables the usage of said bed as said double-decker bed.   
   
   
       13 . The method of  claim 12 , wherein a first mattress is placed in said first frame and a second mattress is placed in said second frame. 
   
   
       14 . The method of  claim 12 , wherein said mechanism is at least one of: electrical, mechanical, and pneumatic. 
   
   
       15 . The method of  claim 12 , further comprising:
 locking said mechanism in place using at least a safety latch.   
   
   
       16 . The method of  claim 15 , wherein said safety latch is placed in its position using at least one of a manual process and an automatic process. 
   
   
       17 . The method of  claim 12 , wherein said vertically move comprises the use of at least one of the following forces: electrical, mechanical, and pneumatic. 
   
   
       18 . The method of  claim 12 , further comprising:
 causing said mechanism to vertically move said first frame with respect to a floor.   
   
   
       19 . The method of  claim 12 , further comprising:
 sensing a pressure on said first frame using a pressure sensor coupled to said first frame; and   sensing a pressure on said second frame using a pressure sensor coupled to said second frame.   
   
   
       20 . The method of  claim 19 , further comprising disabling said vertical motion when said pressure is above a threshold.
