Bed with emergency head release and automatic knee down
First Claim
Patent Images
1. A bed comprising:
- a body support assembly havingan upper body section,a lower body section pivotally connected to the upper body section,a lower drive connected to the lower body section for moving the lower body section to different positions;
an upper drive;
a release mechanism connected to the upper body section for releasably connecting the upper body section to the upper drive thereby allowing the upper drive to move the upper body section to different positions; and
a manual release control connected to the release mechanism for causing the release mechanism to disconnect the upper body section and the upper drive in response to an actuation of the manual release control, thereby permitting the upper body section to move in a generally downward direction independent of the upper drive; and
a switching circuit responsive to the actuation of the manual release control for automatically commanding motion of the lower body section in the generally downward direction.

Abstract
A manual CPR release for a hospital bed mechanically releases the head section from the head drive motor to quickly lower the head section to a flat position. When the head section reaches its lower limit, a switch is actuated which produces a command signal initiating the operation of both the head and knee drive motors. The knee drive motor lowers the thigh and foot sections to their flat positions and brings them into a coplanar position with the head section. Operating the head drive motor moves the head drive nut back into mechanical engagement with the head section.

- 14. A bed having an upper body section pivotally connected to a lower body section, a lower drive connected to the lower body section and an upper drive, the bed including a release mechanism pivotally connected to the upper body section and releasably connected to the upper drive to disconnect the upper drive from the upper body section in response to a first actuation of the release mechanism, thereby permitting the upper body section to be pulled in a generally downward direction by gravity, the bed comprising a switching circuit responsive to the first actuation of the release mechanism for commanding an operation of the lower drive to initiate motion of the lower body section in a generally downward direction.

23. A bed comprising:
-
a body support frame; a head section having one end; a thigh section having one end pivotally linked to the one end of the head section; a foot section having one end pivotally connected to an opposite end of the thigh section; a lower drive mounted on the body support frame in mechanical communication with the thigh and the foot sections for moving the thigh and the foot sections to different inclined positions; an upper drive mounted on the body support frame and in mechanical communication with the head section for moving the head section to different inclined positions; a release mechanism mechanically connected between the upper drive and the head section for disconnecting the upper drive from the head section in response to an actuation of the release mechanism, thereby permitting the head section to move in a generally downward direction in response to a gravitational force and independent of the upper drive; and a release switch connected to the body support frame and operating the upper drive in response to the actuation of the release mechanism to move the upper drive into a connecting relationship with the head section and the release switch operating the lower drive to move the thigh and the foot sections in the generally downward direction, whereby the head, the thigh and the foot sections move into an approximately coplanar relationship. - View Dependent Claims (24)

25. A bed comprising:
-
a body support assembly having an upper body section, a lower body section pivotally connected to the upper body section, a lower drive connected to the lower body section for moving the lower body section to different positions; an upper drive; means connected to the upper body section for releasably connecting the upper body section to the upper drive thereby allowing the upper drive to move the upper body section to different positions; and manually actuated means connected to the means for releasably connecting for disconnecting the upper body section and the upper drive in response to a actuation of the manually actuated means, thereby permitting the upper body section to move in a generally downward direction independent of the upper drive; and means responsive to the actuation of the manually actuated means for automatically initiating motion of the lower body section in the generally downward direction. - View Dependent Claims (26)
