Abstract

There is described a patient lift apparatus comprising a supporting frame, a boom portion connected to the supporting frame, and a spreader element coupled to the boom portion via a coupling member. The boom portion and coupling member are joined by a pivot joint allowing the coupling member and associated spreader element to pivot with respect to the boom portion about a pivot axis. The patient lift apparatus can include a damping element coupled between the boom portion and the coupling member to damp rocking movement of the coupling member and spreader element, which damping element is a linear damper having a first end connected to the boom portion and a second end connected to the coupling member. The patient lift apparatus can include a quick release mechanism to release the spreader element from the boom portion.

A patient lift apparatus comprising a supporting frame, a boom portion connected to the supporting frame, and a spreader element coupled to the boom portion via a coupling member,

wherein the boom portion and coupling member by a pivot joint allowing the coupling member and associated spreader element to pivot with respect to the boom portion about a pivot axis,
wherein the patient lift apparatus further comprises a quick release mechanism to release the spreader element from the boom portion,
and wherein the quick release mechanism is an integral part of the coupling member, wherein the coupling member comprises a first coupling element that is pivotably coupled to the boom portion and a second coupling element that is connected to the spreader element via a point of attachment and releasably coupled to the first coupling element, thus forming a releasable coupling section between the first and second coupling elements allowing selective release of the spreader element from the boom portion.

Dependencies are inferred from the claim text.
