Abstract
An adjustable wall-spacer is employed to position an adjustable hospital bed normally from a wall and prevent contact of the headboard with the wall when the bed is moved into raised or tilted positions.
Claims13
An adjustable hospital bed having a relatively fixed frame having side rails and head and foot portions, a movable frame having a headboard mounted thereon, and having head and foot portions, said bed having a normal position wherein said headboard is substantially parallel with an adjacent wall of a hospital room, elevation linkage interconnecting said movable frame with said fixed frame to elevate said movable frame, said linkage also being adapted to elevate the head portion of said movable frame into a reverse Trendelenberg tilt position, and operable to elevate the foot portion of the movable frame into a Trendelenberg tilt position, and an adjustable wall spacer attached through pivot means to said adjustable frame, said wall spacer comprising:
- pivot means;
- two tubes having guide bushings provided therein, each of said tubes attached through said pivot means to one of said side rails;
- a U-shaped tube having two legs, each of said legs slidably received by said guide bushings;
- two tenons, each attached to one leg of said U-shaped tube;
- and
- two U-shaped strike members, each attached to one of said side rails and each having an aperture in the top thereof and an aperture and an elongated notch in the bottom thereof, said strike members each positioned to receive a tenon selectively within either of said apertures.
An adjustable hospital bed comprising:
- a base frame having a head end and a foot end;
- a movable frame located above the base frame and also having a head end and a foot end located respectively above the head end and foot end of the movable frame;
- means for supporting the movable frame above the base frame and for changing the inclination of the movable frame relative to the base frame such that the head end of the movable frame may be depressed with respect to the foot end of that frame;
- and a wall spacer located on the base frame at the head end thereof and including a bumper member, mounting means supporting the bumper member on the base frame such that the bumper member can both pivot and extend and retract so as to undergo both translatory and rotational movement with respect to the base frame, the mounting means permitting the bumper member to move between a retracted position wherein the bumper member does not project substantially beyond the head end of the movable frame and an extended position wherein the bumper member projects substantially beyond the head end of the movable frame, and further permitting the bumper member to swing downwardly so as to not interfere with the movable frame when the head end of the movable frame is depressed, and latching means for holding the bumper member firmly in its extended position.
An adjustable hospital bed comprising:
- a base frame having a head end and a foot end;
- a movable frame located above the base frame and also having a head end and a foot end which are located respectively over the head end and foot end of the base frame;
- a headboard attached to the head end of the movable frame and projecting upwardly therefrom;
- means for supporting the movable frame above the base frame and for further changing the inclination of the movable frame from a horizontal disposition to an inclined disposition in which the head end of the movable frame is depressed with respect to the foot end of the movable frame, whereby the upper end of the headboard will project beyond the head end of the movable frame;
- and a wall spacer mounted on the base frame at the head end thereof and including a bumper member that is capable of undergoing translatory movement between extended, retracted and intermediate positions, the bumper member when in its extended position projecting beyond the furthest reach of the headboard when the movable frame is inclined with its head end depressed, the bumper member when in its intermediate position projecting beyond the headboard when the movable frame is in a horizontal disposition, but not beyond the headboard when the movable frame is inclined with its head end depressed, the bumper member when in its retracted position being located inwardly from the position it assumes when it is in its intermediate position, and latching means for holding the bumper member firmly in its extended and its intermediate positions.
