EXTENDABLE BED OPTION FOR BED SUPPORTED ON CABLES

    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 an extendable person-support apparatus.

    Patients in healthcare facilities can vary in height. Some patients are short and do not occupy a complete person-support apparatus leaving some space left unused, while others are taller and can require a larger person-support apparatus. One way is to provide a person-support apparatus whose length can be adjusted according to the requirement. 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 which can be extended according to the length of the patient and/or size of the mattress. The person-support apparatus can include a plurality of independent cables, pulleys, a carriage, and a turnbuckle. The cables can be routed through the pulleys and the carriage. The rotation of the turnbuckle can result in to and fro movement of the carriage which in turn causes a change in the length of the person-support apparatus. The person-support apparatus can also include a tensioning feature at an anchor plate for fine tuning of the cable length.

    Figure 1 is a top view of a person-support apparatus 10 showing a mechanical assembly 12 capable of changing the length of the person-support apparatus 10. The mechanical assembly 12 can be coupled to a lower frame 14 of the person-support apparatus 10. The mechanical assembly 12 can change the length of the person- support apparatus 10 by approximately four inches according to the length of the patient or the size of mattress assembly (not shown). It should be appreciated that the length of the person-support apparatus can also be changed by a value other than 4 inches. The mechanical assembly 12 can include at least two independent cables present on both side of an axis X1 - X1 as shown in Fig. 1. The arrangement of independent cables 16 and 18 at one side can be mirror image of the independent cables 20 and 22 on the

other side of the axis X1 - X1. At one of the side of axis X1 - X1, the one end of a first independent cable 16 can be fixed and attached to the frame 14 at an anchor plate 24 present on the head end 26 of the person-support apparatus 10. The first independent cable 16 can pass through a first pulley 28, a second pulley 30, and can be connected to a first turnbuckle 32 at the other end. A second independent cable 18 can be attached to the first turnbuckle 32 and can be connected to the frame 14 at a foot end 34 of the person-support apparatus 10 after passing through a third pulley 36....
