Mattress Corner Lifting Device

Abstract

A mattress corner lifter that includes a base and a lifting mechanism supported by the base. Also, a platform is rotatably supported at the top of the lifting mechanism. The lifting has a compressed state, an extended state and an intermediate state between the compressed and extended states. In the compressed state the mattress lifter pushes up with a force of less than 25 lbs, but in its intermediate state the force with which the mattress lifter presses up increases as the mattress lifter extends, until it reaches a maximum of at least 40 lbs, and wherein at the extended state the mattress lifter resists compression with a force of at least 40 lbs.

1 . A mattress corner lifter, comprising:
 a) a base,   b) a lifting mechanism supported by said base; and   c) a platform rotatably supported at said top of said lifting mechanism;   d) wherein said lifting has a compressed state, an extended state and an intermediate state between said compressed and extended states and wherein in said compressed state said mattress lifter pushes up with a force of less than 25 lbs, but in its intermediate state the force with which said mattress lifter presses up increases as said mattress lifter extends, until it reaches a maximum of at least 40 lbs, and wherein at said extended state said mattress lifter resists compression with a force of at least 40 lbs.   
     
     
         2 . The mattress corner lifter of  claim 1 , wherein said platform is rotatably mounted in one rotational dimension, only. 
     
     
         3 . The mattress corner lifter of  claim 1 , wherein said platform is rotatably mounted in more than one rotational dimension. 
     
     
         4 . The mattress corner lifter of  claim 1 , wherein said platform is made of acrylonitrile butadiene styrene (ABS) polymer.
