HEIGHT ADJUSTABLE PERSON-SUPPORT APPARATUS

    The present disclosure relates generally to a person-support apparatus, such as, a hospital bed. More specifically, but not exclusively, one illustrative embodiment relates to a height adjustable person-support apparatus.

    Generally, a person-support apparatus can be provided with a mechanism to adjust the height of the person-support apparatus. The height of the person-support apparatus can be optimized based on the height of the patient for ingress/egress. Further, the height can also be adjusted depending on the height of the caregiver. While some person-support apparatus have been developed, there is still room for improvement. Thus, a need persists for further contributions in this area of technology.

    The disclosure provides a person-support apparatus with a height adjustment mechanism configured to change the height of the person-support apparatus. The person-support apparatus includes a plurality of cables, a plurality of pulleys, a carriage plate and a lead screw. The cables can be routed through the pulleys present on the carriage plate and connected to the legs of the person-support apparatus. The lead screw can be configured to rotate and move the carriage plate back and forth to change/adjust the height of the person-support apparatus.

    Figure 1 is a top view of a person-support apparatus 10 showing a height adjustment mechanism 12 or a Hilo mechanism 12 capable of changing the height of an upper frame 16 of the person-support apparatus 10 with respect to a lower frame 14 of the person-support apparatus 10. The height adjustment mechanism 12 can be installed on at least one of the lower frame 14 and the upper frame 16 of the person- support apparatus 10. It should be appreciated that the upper frame 16 can be supported by a plurality of supports 18 above the lower frame 14. It should also be appreciated that the lower frame 14 can be supported on four legs L1, L2, L3 and L4 or casters present at each corner.

    The height adjustment mechanism 12 can include at least three cables present on both side of an axis X1 - X1 as shown in Fig. 1. The arrangement of cables at one

side of the axis X1 - X1 can be mirror image of the cables on the other side of the axis X1 - X1. For the sake of brevity, the arrangement of cables on one side of the axis X1 - X1 will be described in further detail below.

    A perspective top view of the person-support apparatus 10 along with the height adjustment mechanism 12 can be shown in Fig. 1. Another perspective side view of the person-support apparatus 10 along with the arrangement of pulleys and cables can be shown in Fig. 2. At one of the side of axis X1 - X1, one end E1 of a first cable 20 and a second cable 22 can be anchored to an anchor plate 24 present on a head end 26 of the person-support apparatus 10 as shown in Fig. 1 and Fig. 2. The first cable 20 can pass through a first pulley 28 and a second pulley 30 and...
