Definitions
- the present invention relates to a safety hook for mounting on the extremity of a spreader bar of a patient lift of the type that comprises a base member, a load- bearing hook member extending in a first plane and having a first end and a second free end.
- the hooks on the extremities of the spreader bar of a patient lift used for attaching a sling, harness or lifting belt to the spreader bar of a patient lift are normally provided with measures to minimize the risk of unintentional release of the attachment loops at the free ends of the support straps of the sling, harness or lifting belt.
- measures usually comprise double hooks creating a labyrinth, corkscrew hooks, or resilient clips (snap finger) or other resilient means that close the opening of a simple hook. All of these measures have in common that the operation of attaching and detaching an attachment loop from the hook is cumbersome and the operator usually needs to use both hands .
- a safety hook for a patient lift of the kind referred to initially that allows comfortable detachment and attachment of attachment loops.
- This object is achieved in accordance with claim 1 by providing a hook of said kind in which the first end is pivotally suspended from the base member at a pivot axis to allow the hook member to move in the plane of the hook member between an open position and a closed position in which the free end of the hook member engages the base member at an engagement point, and whereby the hook member extends from the pivot axis to one side of a second plane which falls together with the pivot axis and the engagement point, the hook member extending further through the second plane to its free end.
- the hook member is shaped such that it is urged to the closed position when a downward load is applied to it, and urged to the open position when an upward load is applied to it. Under normal circumstances the safety hook closes automatically under the weight of the load.
- Unintentional opening of the safety hook is excluded as there can there cannot be an upward load under normal circumstances.
- Releasing a sling or lifting belt from the safety hook is very simple, the operator merely needs to pull the attachment loop of the sling or lifting belt upwards to open the safety hook and the attachment loop can be released.
- the safety hook may comprise means for retaining the hook member in the closed position, these means preferably comprising a resiliently biased locking member in the base member for engaging a first recess in the hook member.
- the safety hook may comprise means for retaining the hook member in the open position, these means preferably comprising the resiliently biased locking member in the base member for engaging a second recess in the hook member.
- the hook member can remain in the open position for attaching or detaching a load such as the attachment loop of a sling.
- the safety hook may be constructed such that the free end of the hook member positively engages the base member at the engagement point, preferably by complementary shapes provided on the free en of the hook member and on the base member at the engagement point .
- the base member can an integral part of the spreader bar or can be attached to the spreader bar.
- the second plane is preferably substantially parallel with the spreader bar, with the hook member extending downwards from the pivot axis so that a downward load applied on the hook member urges it to the closed position.
- the hook member preferably comprises a part proximate to the free end that extends substantially parallel with the spreader bar so that an upward load applied on the hook member urges it to the open position.
- Fig. 1 is a view of a part of a patient lifting system
- Fig. 2 is a side view of a spreader bar provided with safety hooks according to the present invention
- Fig. 3 is a perspective view of a safety hook according to the present invention.
- Fig. 4 is a cross-sectional view of the safety hook according to the present invention in an open position
- Fig. 5 is a cross-sectional view of the safety hook according to the present invention in a closed position.
- FIG. 1 A part of a patient lift system is illustrated in Fig. 1, comprising a spreader bar 1 suspended from a connection point 4 in the middle on top by a strap or wire from a not shown lifting device.
- Suitable lifting devices are e.g. ceiling lifts operating with an overhead rail from which the spreader bar is suspended by a strap, or cable, usually via a winch, or - floor lifts operating with a wheeled frame provided with a mast and a lifting arm to which the wire or strap is connected, all well known in the art.
- Hook members 2 extend from both horizontal extremities of the spreader bar 1.
- the patient to be lifted is carried by a sling 3.
- the sling 3 is provided with a plurality of support straps provided with attachment loops at their free ends .
- the attachment loops are securely hung over the safety hooks 2.
- Other types of slings such as walking slings, stretcher slings, lifting belts, patient harness or other devices used for supporting a patient to be lifted can be used instead of the sling shown in Fig. 1.
- Fig. 2 shows a side view of the spreader bar 1 in greater detail.
- the spreader bar 1 is shaped as a curved bar (straight bars, or bars formed by two straight parts at an angle (cf . Fig. 1) are equally suitable) .
- a base member 5 of the safety hook according to the invention is mounted at each horizontal extremity of the spreader bar 1.
- a hook member 2 is suspended from each of the base members 5.
- Fig. 3 shows a perspective view of a safety hook according to the invention in even greater detail.
- the main body of the base member 5 is formed by a substantially cylindrical body, but any other shape could be used instead.
- the hook member 2 is at a first end suspended from the base member 2 by a pivot shaft 8.
- the second free end of the hook member 2 is provided with a substantially ball shaped projection 6.
- the base member is provided with a complementary spherical recess 7 for receiving the ball shaped projection 6.
- Figs . 4 and 5 show a safety hook according to the
- the base member 2 is provided with a slot 14 for receiving a part of the hook member 2.
- the pivot shaft 8 extends through the slot 14 and through the first end of the hook member 2, allowing the latter to be suspended from the base member so that it can rotate in the plane of the hook member 2 between an open position (cf. Fig. 4) and a closed position (cf. Fig 5) .
- the base member is provided with a channel 9 that opens into the slot 14 so that it faces the first end of the hook member 2.
- a spring 11 arranged in the channel 9 urges a ball 10 towards the first end of the hook member 2.
- the first end of the hook member 2 is provided with a recess 12 for engaging the spring loaded ball 10 in the closed position, and with a with a recesses 13 for engaging the spring loaded ball 10 in the open position.
- an attachment loop of e.g. a sling 3 can easily be hung over the hook member 2. This operation can, if necessary, be carried using only one hand, since the hook member 2 stays in the open position because the gravity force caused by the weight of the hook member 2 alone is not sufficient to overcome the resistance of the spring loaded ball 10.
- the downward force applied to the hook member is big enough to overcome the retaining force created by the spring loaded ball 10 and the hook member moves to the closed position in which the ball shaped protrusion 6 at free end of the hook member 2 positively engages the spherical recess 7 at a contact point 15.
- the positive engagement increases the overall stability of the safety hook, and minimizes the risk of deformation of the hook member 2 under excessive load.
- the hook member 2 and the base member 5 form a closed loop and as long as the hook member 2 stays in the closed position any attachment loops hung over the hook member 2 cannot be unintentionally be disengaged from the safety hook.
- the spring loaded ball 10 ensures that the hook member 2 also remains in the closed position even if the load does not apply a downward force, e.g. for short periods of time caused by violent movements of the spreader bar 1. The risk of an attachment loop of a sling 3 to disengage unintentionally is therefore minimized.
- the attachment loop can be disengaged from the safety hook by a user simply pulling the attachment loop upwards with a force sufficient to overcome the retaining force of the spring loaded ball 10, and thus move the hook member 2 to the open position where it is retained again by the spring loaded ball 10.
- the attachment loop or loops can be removed from the hook member 2 to disengage the sling 3
- Line 16 represents an imaginary plane that falls together with the pivot axis of shaft 8 and the contact point 15 where the free end 6 of the hook member 2 engages the base member 5.
- the hook member 2 extends from its first end to the lower side of the imaginary plane and turns upwards though the imaginary plans until its free end that is on the upper side of the imaginary plane. Any such shaped hook member is suitable for use with the present invention, since it will automatically lock under load.
- the use of the safety hook as described with reference to the preferred embodiments is not limited to mounting on spreader bars of ceiling lifts.
- the lifts could be floor lifts, and the hook may e.g. also be mounted on the end of the lifting arm of a floor lift.
