A width variation system for a person support apparatus

This disclosure generally relates to a person support apparatus. More specifically, but not exclusively, the disclosure relates to a width variation system for the person support apparatus.

Generally, a healthcare facility is equipped with a number of person support apparatuses. There may be situations, such as, transfer of the person support apparatus through a door of a width lesser than a width of the person support apparatus. In those situations, the width of the person support apparatus is required to be adjusted. The width of the person support apparatus is adjusted automatically in existing systems using a motor. The motor may give power to adjust a position of the support surface of the person support apparatus which may adjust the width of the person support apparatus. In certain situations, such as, electricity failure, motor failure, electronic control failure, and the like, the motor may fail to deliver power to adjust the position of the support surface, thereby, failing to adjust the width of the person support apparatus.

            The disclosure relates in general to a width variation system for a person support apparatus. The person support apparatus includes at least one support surface for supporting a deck. A width of the person support apparatus may be adjusted by the width variation system. The width variation system comprises a powered screw, a couple of half nuts, and a plurality of tilt linkages. The power screw rotates at a fixed position. The couple of half nuts are connected to the support frame. The couple of half nuts are configured to convert a rotational motion of the couple of half nuts to translational motion of the support frame when engaged with the powered screw and sets free the support frame when disengaged with the powered screw.

A width variation system 110 for a person support apparatus is shown in FIG. 1. The person support apparatus includes at least one support surface 105 on which a deck may rest. The at least one support surface 105 may rest on rails defined on the person support apparatus. In an embodiment, the person support apparatus herein may include a couple of support surfaces defining a width of the person support apparatus by a distance between the couple of support surface. In another embodiment, the person support apparatus may include a single support surface defining the width of the person support apparatus by a distance between the single support surface and a fixed surface. However, the present disclosure is explained as the couple of support surface supporting the deck as an example.

The width of the person support apparatus may be varied by varying a position of the at least one support surface 105, thereby varying the distance between the couple of support surfaces 105 in the present embodiment. The position of the at least one support surface 105 may be varied by using the width variation system 110. The width...
