(13) Referring to FIGS. 4 and 5, the curtain changing apparatus 100 comprises an insert retrieval tool 130 which is adapted to enable removal of the insert 120 and replacement of the insert 120 from ground level for normal use. The insert removal tool 130 is in the form of a T-shaped tool comprising an arm member 131 and a retrieval portion 132 attached to the top of the arm member 131 such that the retrieval portion 132 lies perpendicular to the arm member 131. It is envisaged that the arm member 131 can be provided in varied lengths and/or can be adjustable in length. Provided at the base of the arm member 131 is a rubber stop member 136. The retrieval portion 132 is preferably L-shaped having a base member 133 and a side member 134 integrally formed such that the base member 133 and a side member 134 lie at right angles to one another. The arm member 131 at its top end 135 is attached to an underside of the base member 133. The side member 134 has provided at least one slotted portion 137. According to a preferred embodiment, a pair of slotted portions 137 is provided. The pair of slotted portions 135 is substantially curved and is adapted to receive and securely hold the latching member(s) 125 of the insert 120 therein. An opening 138 of the slotted portions 137 is slightly larger in width and tapers inwardly to the body 139 of the slotted portions 137 such that the latching member can be received within the opening 138 and retained within the smaller width of the body 139 of the slotted portions 137, as illustrated in FIG. 5. It will be acknowledged that any other suitable means of connection between the insert 120 and insert retrieval tool 130 could also be adopted.

(14) Referring to FIG. 6, the curtain changing apparatus 100 comprises a curtain retrieval arm 140. The curtain retrieval arm 140 comprises an upper arm 141 and a lower arm 142. Provided at the base of the lower arm 142 is a stopper member 151. The upper arm 141 comprises a straight portion 141a and a curved section of track 141b. The curved section of track 141b of the upper arm 141 comprises an extruded elongate member having a pair of spaced apart downwardly extending flanges 144 which form a channel 145. A pair of locator plates 146 is secured to either side of the curved track section 141b via at least one fastener which passes through corresponding apertures provided in the locator plates 146 and curved track section 141b. The at least one fastener can be a screw or bolt or any other suitable fastening means. A retention means 149 is provided within the curved track section 141b positioned between the locator plates 146 to enable the curtain retrieval arm 140 to be received and held within the full or partial cutout portion 113 of the track 110.

(15) The curtain retrieval arm 140 is telescopic to be adaptable to suit tracks mounted at different heights curtains mounted at different heights whereby the upper arm 141 and lower arm 142 can be slidably moved in relation to each other. The upper arm 141 comprises a shaft 141c which is adapted to be slidably received within the lower arm 142. As illustrated in FIG. 6, a locking mechanism 150, such as a knob or the like, is provided which is adapted to lock the upper arm 141 within the lower arm 142. The securing/release device 150 is in the form of a screw knob which is movable between a first locked position wherein the button extends through at least one corresponding aperture provided on the upper arm 141 and lower arm 142 and a second unlocked position wherein the securing/release knob is retracted from the at least one aperture provided on the upper arm 141, and possibly but not necessarily the lower arm 142, to enable the lower arm 142 to be slidably movable relative to the upper arm 141 of the curtain retrieval arm 140, to compliment varying track types and installation heights. However, in an alternative embodiment is it envisaged that any other suitable locking means could be utilised such as, a depressible button or the like.

(16) A method of changing the curtain using the curtain changing apparatus 100 of the present invention is provided. The insert 120 is removed from the track 110 using the insert retrieval tool 130. To remove the insert 120, the pair of latching members 125 on the insert 120 is aligned with the slotted portions 137 on the insert retrieval tool 130. The insert retrieval tool 130 is then pushed in an upward direction followed by a sideward direction, dependent on the shape of the slotted portions 137, such that the fasteners 125 are received and secured/locked within the slotted portions 137. When the insert 120 is firmly secured within the insert retrieval tool 130, the insert retrieval tool 130 can then be pulled downwardly to release the magnetic force and remove the insert 120 from the curtain track 110. Once the insert 120 is removed, the curtain retrieval arm 140 can be inserted into the track 110. The height of the curtain retrieval arm 140 can then be adjusted and locked into place from ground level utilising the locking mechanism 150 on the curtain retrieval arm 140. When the curtain retrieval arm 140 is securely in position, a dirty curtain can be pulled into the curtain retrieval arm 140 which enables the curtain to drop down to a waist height position where the dirty curtain 160 can easily and safely be unhooked for cleaning and a clean curtain can be hooked and slotted back into the curtain retrieval arm 140 to be dragged up onto the track 110, as illustrated in FIG. 7. The curtain retrieval arm 140 is then removed and the insert 120 replaced back into its normal position for daily use.

(17) It is envisaged that the curtain changing apparatus will be provided in two forms. A retrofit form, as detailed above, to accommodate existing tracking external dimensions and wheeled curtain hooks by removing a section of the existing track and joining an equivalent length section of track to accommodate the interchangeable insert of the present invention. In an alternative embodiment, a new installation form will have a larger wheeled curtain hook to eliminate snagging of the hook on the track joins, which is a common issue in current installations. Accordingly, the external dimension of the track will match existing commercially available tracks while the internal dimension of the track and channel can be enlarged to accommodate a larger wheeled curtain hook.

(18) Hence, the curtain changing apparatus provides a solution to the aforementioned problems of the prior art by providing a curtain changing apparatus which enables a curtain to be loaded or unloaded from a curtain track in any position in the girth of the track, enabling access in the centre of rooms with trolleys holding clean curtains and not limited to the end of tracks in the corner of rooms, as per current products. The curtain changing apparatus of the present invention enables the use of commonly available swivel wheeled carriers as opposed to fixed glides which catch on track joins and cannot be used with current disposable curtains. The curtain retrieval arm of the present invention does not need to be held and once it has been slotted into the curtain track and its height is adjusted and locked to suit the height between the curtain track and the floor, the curtain retrieval arm will be freestanding avoiding the need to support the weight of the arm and curtain which would otherwise require support. The present invention enables the changing of healthcare curtains from a standing ground-based position without the need to reach and climb and stand or steps or ladders or the like that could lead to injury.

(19) The reference to any prior art in this specification is and should not be taken as, an acknowledgment or any form or suggestion that the prior art forms part of the common general knowledge.

(20) Throughout the specification the aim has been to describe the invention without limiting the invention to any one embodiment or specific collection of features. Persons skilled in the relevant art may realize variations from the specific embodiments that will nonetheless fall within the scope of the invention.
