Abstract
A bed is provided for supporting a patient thereon. The bed includes a first bed component that is movable relative to a second bed component. The bed further includes a position detector configured to detect the position of the second bed component relative to the first bed component.
Claims29
A bed comprising
- a support surface configured to support a person,
- a bedframe configured to support the support surface, the bedframe including a first component and a second component configured to move relative to the first component between a first and a second position, and
- a position detector including a conductor and a sensor, the conductor having a property changeable between first and second states, the second component of the bedframe being positioned to change the property of the conductor from the first state to the second state upon movement of the second component from the first position to the second position, the sensor being coupled to the conductor to detect the state of the property of the conductor to determine the position of the second component relative to the first component.
A bed comprising
- a support surface configured to support a person,
- a bedframe configured to support the support surface, the bedframe including a frame member and multiple components configured to move relative to the frame member between first and second positions, and
- a position detector including a conductor and a sensor, each of the multiple components being positioned to communicate a change in position of said component to the conductor, the sensor being coupled to the conductor to detect the change in position of each of the multiple components to determine the positions of the components.
A bed comprising

- a bedframe configured to support the support surface, the bedframe including a frame member and multiple components configured to move relative to the frame member between first and second positions,
- a position detector including a conductor and a sensor, each of the multiple components being positioned to communicate a change in position of said component to the conductor, the sensor being coupled to the conductor to detect the change in position of each of the multiple components to determine the positions of the components, and
- a board defining the support surface, the multiple components being latches positioned to move between the first position latching the board to the frame member and the second position permitting the board to be removed from the frame member.

A bed comprising
- a support surface configured to support a person,
- a bedframe configured to support the support surface, the bedframe including a frame member and a latch configured to move relative to the frame member between a first position and a second position, the latch being further configured to couple the support surface to the frame member when in the first position and to permit the support surface to be removed from the frame member when in the second position, and
- a position detector including a conductor and a sensor, the conductor having a property changeable between first and second states, the latch of the bedframe being positioned to change the property of the conductor from the first state to the second state upon movement of the latch from the first position to the second position, the sensor being coupled to the conductor to detect the state of the property of the conductor to determine the position of the latch relative to the frame member.
