Tilt-Prevention Mechanism For Adjustable Bed
Tilt-Prevention Mechanism For Adjustable Bed
US Patent:
4628556, Dec 16, 1986
Filed:
May 10, 1984
Appl. No.:
6/609003
Inventors:
Lionel H. Blackman - West Palm Beach FL
International Classification:
A47C 2108, A47C 2100, A61G 700
US Classification:
5424
Abstract:
A tilt-preventing mechanism for a height-adjustable bed of the type including a mattress which is supported in a substantially horizontal position on a support structure which can be moved up and down by means of an electric motor. When the mattress, or its support structure, encounters during its up or down movement an obstruction which causes one region of the mattress to discontinue its movement while other regions continue to move with attendant tilting of the mattress, a position-sensitive switch arrangement of the mechanism senses the tilting and, once the degree of tilt approaches or reaches the limit of acceptable tilting, inactivates the motor so that the tilting is not aggravated any more. The position-sensitive switch arrangement includes one or two switches arranged normal to the expected axis or axes of tilting and moving with the support structure. The position-sensitive switches can be constructed as mercury switches.
