Abstract
There is described a patient lift apparatus (1) comprising a supporting frame (10), a boom portion (18) connected to the supporting frame (10), and a spreader element (25) coupled to the boom portion (18) via a coupling member (20). The boom portion (18) and coupling member (20) are joined by a pivot joint (PJ2) allowing the coupling member (20) and associated spreader element (25) to pivot with respect to the boom portion (18) about a pivot axis (PA2). According to one aspect of the invention, the patient lift apparatus (1) further comprises a damping element (50) coupled between the boom portion (18) and the coupling member (20) to damp rocking movement of the coupling member (20) and spreader element (25), which damping element (50) is a linear damper having a first end (50A) connected to the boom portion (18) and a second end (50B) securely fastened to the coupling member (20) at a point of attachment that is offset with respect to the pivot axis of the pivot joint. According to another aspect of the invention, the patient lift apparatus (1) further comprises a quick release mechanism (30, 200) to release the spreader element (25) from the boom portion (18). Any rocking motion while lifting a patent with a lifting apparatus could potentially cause injuries to the patient and/or to the caregivers and medical staff handling the apparatus. The invention includes a damper within the lift apparatus, reducing patient rocking during lifting.
Claims (19)
1. 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 are joined by a pivot joint 5 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 damping element coupled between the boom portion and the coupling member to damp rocking movement of the coupling member and spreader element, 10 and wherein the damping element is a linear damper having a first end connected to the boom portion and a second end pivotally and securely fastened to the coupling member at a point of attachment that is offset with respect to the pivot axis of the pivot joint. 15
2. The patient lift apparatus according to claim 1, wherein the damping element is a pneumatic or hydraulic damper.
3. The patient lift apparatus according to claim 1 or 2, wherein the damping element is located completely within an inner space of the boom portion.
4. The patient lift apparatus according to claim 1, further comprising a quick release mechanism to release the spreader element from the boom portion.
5. The patient lift apparatus according to claim 4, wherein the quick 25 release mechanism is an integral part of the coupling member, which 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 and releasably coupled to the first coupling element, thus forming a releasable coupling section between the first and second coupling elements. 15943492_3 December 3, 2018
6. The patient lift apparatus according to claim 5, wherein the second end of the damping element is connected to the first coupling element at the point of attachment. 5
7. The patient lift apparatus according to claim 5 or 6, wherein the releasable coupling section is designed as a dovetail connection between the first and second coupling elements.
8. The patient lift apparatus according to claim 7, wherein the first 10 coupling element comprises a T-shaped extension and the second coupling element comprises a corresponding T-shaped opening adapted to receive the T- shaped extension and secure the first coupling element to the second coupling element. 15
9. The patient lift apparatus according to claim 5 or 6, wherein the second coupling element is releasably translatable with respect to the first coupling element.
10. The patient lift apparatus according to claim 9, wherein translation 20 of the second coupling element with respect to the first coupling element takes place along an inclined plane.
11. The patient lift apparatus according to claim 9, wherein the releasable coupling section is designed in such a way that the second coupling 25 element comes to rest against the first coupling element and is supported by the first coupling element when coupled one with the other.
12. The patient lift apparatus according to claim 5 or 6, wherein the releasable coupling section is designed in such a way that complete coupling of 30 the second coupling element onto the first coupling element is ensured by gravity and wherein the second coupling element is automatically locked onto the first 15943492_3 December 3, 2018 coupling element upon complete coupling of the first and second coupling elements.
13. The patient lift apparatus according to claim 5 or 6, wherein the 5 quick release mechanism further comprises a locking-unlocking mechanism adapted to automatically lock and secure the first and second coupling elements one with the other and to manually unlock and release the first and second coupling elements one from the other. 10
14. The patient lift apparatus according to claim 13, wherein the locking- unlocking mechanism comprises a movable locking member that is adapted to move alongside a guide portion of the first coupling element between a locking position, in which the movable locking member partly engages into a retaining portion provided in the second coupling element, and an unlocking position, in 15 which the movable locking member is disengaged from the retaining portion.
15. The patient lift apparatus according to claim 14, wherein the movable locking member is designed to slide inside a hollow portion of the first coupling element, which hollow portion acts as the guide portion, and to 20 cooperate with a corresponding bore provided in the second coupling element, which bore acts as the retaining portion.
16. The patient lift apparatus according to claim 14, wherein the movable locking member is moved to the locking position and pressed into 25 engagement with the retaining portion under the action of a spring and wherein the movable locking member is selectively movable to the unlocking position and disengaged from the retaining portion under the action of a manually-actuatable release knob. 30
17. The patient lift apparatus according to claim 16, wherein the manually-actuatable release knob is positioned along the guide portion and forms an integral part of the movable locking member. 15943492_3 December 3, 2018
18. The patient lift apparatus according to any one of claims 4 to 6, wherein the quick release mechanism is designed to allow toolless release of the spreader element.
19. The patient lift apparatus according to claim 1, substantially as herein claimed with reference to any embodiment disclosed. 15943492_3 December 3, 2018 1 / 11
