Definitions
- the present invention relates to a hospital bed having a frame with two articulated pairs of wheels, between which is arranged an articulated or non-articulated pair of wheels.
- articulated wheel here means a wheel supported by a bearing housing pivotable about a vertical axis.
- the object of the present invention is to provide a solution to these and other associated problems.
- the hospital bed according to the invention is characterized in that the intermediate pair of wheels is spring-supported at the frame, and in that a ratchet for the intermediate pair of wheels is arranged on the bed and designed to block the direction of movement of the wheels and possibly also lock this pair of wheels and, in unlocked position, to allow the wheels in this pair to move freely.
- the construction is intended to facilitate transport of the bed from place to place. Transport of such a bed can easily be performed by one person since the bed pivots about a fulcrum at the intermediate pair of wheels.
- the intermediate pair of wheels being spring-supported means that, even when the bed is stationary, all six wheels reach the floor, the middle pair under a certain pressure, thus ensuring that a person lying in the bed is not subjected to unpleasant tilting, while at the same time the intermediate pair of wheels facilitates transport of the bed from place to place.
- the bed frame can be used for old beds as well as new ones.
- Figure 1 shows a bed frame, seen from the side.
- Figure 2 is a section along the line A - A in Figure 1
- Figure 3 is a section along the line B - B in Figure 1.
- Figure 1 shows the frame (1) of a hospital bed according to the invention.
- the bed (frame) is provided in conventional manner with two articulated pairs of wheels (9), with one wheel at each corner.
- the wheels are articulated and, as mentioned, manipulation of a bed with only these wheels is cumbersome.
- the bed is provided with an intermediate pair of wheels (2), the two wheels of which are supported by vertical shafts (3) arranged in the frame.
- the intermediate wheels are spring-supported in relation to the frame (1), in this case by helical springs (4) around the support shafts (3), the springs being clamped between washers (6) welded to the support shafts and wheel houses for these wheels (2). See Figure 3.
- the aim is that, when the bed is stationary and during transport, all six wheels shall be in contact with the floor, the intermediate wheels being under a certain pressure. When the bed is stationary, therefore, it cannot tip over. At the same time these intermediate wheels contribute to facilitating transport of the bed.
- Hexagonal apertures (5) for a hexagon bar (7) are provided in the support shafts (3).
- the bar is manipulated from the end of the bed between a locked position (8) and a movable position (8').
- the locked position primarily locks the direction of movement but may also lock the wheels.
- the bed may also be provided with brake members (not shown). Since the bed always stands on six wheels there is no risk of rocking.
- the ratchet means is also shown in Figures 2 and 3. Turning the hexagon bar (7) either locks or releases the middle pair of wheels (2).
