Abstract
An adjustable height platform comprising a bottom platform, a top platform and a scissors linkage secured between the top and the bottom platforms. The scissors linkage includes scissors legs which pivot about a pivot axis. A drive system provides a horizontal force to the scissors linkage. An unlocking mechanism lifts the pivot axis in response to the horizontal force and unlocks the scissors legs from a collapsed, retracted, and aligned position. After unlocking the legs, the horizontal force continues to raise the top platform with respect to the bottom platform.
Claims28
An adjustable height platform system comprising:
- a bottom platform;
- a top platform positioned above the bottom platform;
- a scissors linkage secured between the bottom and the top platforms to raise and lower the top platform with respect to the bottom platform, the linkage having scissors legs which pivot about a pivot axis;
- a drive system for providing a horizontal force to the scissors linkage;
- and
- an unlocking mechanism that lifts the pivot axis in response to the horizontal force to unlock and lift the scissors legs from a retracted and aligned position so that the horizontal force can then be applied to the scissors linkage to raise the top platform with respect to the bottom platform.

An adjustable height bed comprising:
- a bottom platform;
- a top platform positioned above the bottom platform;
- and
- a mechanism contained between the bottom and the top platforms to raise and lower the top platform with respect to the bottom platform;
- in which a distance from a top surface of the top platform to a bottom surface of the bottom platform is less than approximately five inches when the top platform is at its lowest position.

An adjustable height bed comprising:
- a bottom platform;
- a top platform positioned above the bottom platform;
- a mechanism contained between the bottom and the top platforms to raise and lower the top platform with respect to the bottom platform;
- and
- a drive system for providing a horizontal force to the mechanism, the horizontal force resulting in vertical movement of the top platform relative to the bottom platform.

A bedframe comprising;
- a base plate having a head end and a foot end, wherein the base plate contacts and is positioned on a standard floor when the bedframe is in place;
- a mattress support plate having a head end and a foot end that is positioned over the base plate;
- a scissors linkage having at least a first scissors leg and a second scissors leg secured between the base plate and the mattress support plate;
- a drive system positioned above the base plate and connected to the scissors linkage to raise and lower the mattress support plate with respect to the base plate by expanding and retracting the scissors linkage;
- and
- an unlocking mechanism positioned between the base plate and the mattress support plate activated by the drive mechanism to initially expand the scissors linkage from a fully retracted position, wherein the first and second scissors legs lie in the same plane and are parallel to the base plate and the mattress support plate.
3 more elements
A bedframe comprising:
- a base plate having a head end and a foot end;
- a mattress plate having a head end, a foot end, a top and a bottom, that is positioned over the base plate;
- a scissors linkage connected to and contained between the base plate and the mattress plate;
- a drive system connected to the scissors linkage and positioned above the base plate capable of raising the mattress plate at least thirty inches above the base plate and lowering the mattress plate less than ten inches above the base plate;
- and
- an unlocking mechanism positioned above the base plate and below the mattress plate that is connected to the drive system to provide an initial force that includes a vertical component to initially expand the scissors linkage from its completely retracted position.
3 more elements
A bedframe comprising:
- a base plate having a head end and a foot end;
- a mattress plate having a head end and a foot end positioned over the base plate;
- a scissors linkage secured to the mattress plate and the base plate;
- an unlocking mechanism that initially expands the scissors linkage from a fully retracted position;
- a drive system connected to the unlocking mechanism and the scissors linkage to raise and lower the mattress plate with respect to the base plate;
- and
- a pair of side walls that extend between the mattress plate and the base plate that creates an enclosure between the mattress plate and the base plate when the scissor linkage is retracted, such that the scissors linkage and unlocking mechanism are contained within the enclosure.
4 more elements
A bedframe suitable for use in nursing homes comprising:
- a base plate having a head end and a foot end;
- a mattress plate positioned over the base plate having a head end, a foot end and a down turned flange along its sides;
- a scissors linkage between the base plate and the mattress plate to raise and lower the mattress plate with respect to the base plate by expanding and retracting, respectively;
- a safety switch positioned between the base plate and the mattress plate flange that generates a stop signal when the flange contacts the base plate and when an obstruction is lodged between the base plate and the flange;
- a drive system that is connected to the scissors linkage to expand and retract the scissors linkage;
- an unlocking mechanism connected to the drive system that provides a force having a vertical component to initially assist and unlock the scissors linkage;
- and
- a controller communicatively connected to the safety switch that raises and lowers the mattress plate in response to a command received from an input, wherein the controller will cease lowering the mattress plate when the safety switch generates and transmits the stop signal to the controller.
