Description

TRANSFER APPARATUS

FIELD [00001] The present disclosure relates to a transfer apparatus and especially, but not exclusively, to a transfer apparatus for assisting a wheelchair user to transfer himself or herself from a wheelchair to a toilet.

DEFINITION [00002] In the specification, the term “comprising” shall be understood to have a broad meaning similar to the term “including” and will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. This definition also applies to variations on the term “comprising” such as “comprise” and “comprises”.

BACKGROUND [00003] A transfer apparatus in the form of a transfer board is used to assist wheelchair users in their transfer from a wheelchair to a different desired position, such as onto a toilet. A known transfer board is a substantially board-like or plank-like member which can be positioned by the wheelchair user or an associated carer to provide a bridge from the wheelchair to the toilet.

[00004] A known transfer board is thus embodied as a transportable plank to be carried by the wheelchair or carer.

[00005] In use, the transfer board may be positioned so that one end region rests on and is supported by the wheelchair and the other end region rests on and is supported by a toilet. The transfer board may thus be regarded as providing a bridge between the occupied wheelchair and the destination location. When the transfer board is considered to be sufficiently stably positioned, the wheelchair user can shift him or herself from the wheelchair onto the transfer board, and then edge along the board from the wheelchair to the desired location (for example, onto a toilet).

[00006] Wheelchair users have reported difficulty carrying such transfer boards around outside of their homes, as often there is not enough space on a wheelchair to carry it. In turn, this can create difficulties for people in wheelchairs to safely use public toilets, as lack of a transfer board dramatically increases the likelihood of falls.

2018236806 27 Sep 2018 [00007] The reference to prior art in this specification is not and should not be taken as an acknowledgment or any form of suggestion that the referenced prior art forms part of the common general knowledge in Australia or in any other country.

SUMMARY [00008] According to a first aspect of the present disclosure, there is provided a transfer apparatus to assist in transfer of a person between a first location upon a wheelchair and a destination location distinct from the wheelchair where the person is to be supported, the transfer apparatus comprising:

DETAILED DESCRIPTION OF EMBODIMENTS [00150] With reference to Figures 1 to 10, a first embodiment of a transfer apparatus, generally designated by the reference numeral 10, will be described.

[00151] As illustrated in Figures 1 to 3, the transfer apparatus 10 comprises a transfer structure which, in this embodiment, is in the form of a transfer board member 20, and a support structure which, in in this embodiment, comprises a bollard or post 40, which is provided with a support arm 80 attached thereto. A first, or proximal end region of the support arm 80 is connected to the post 40, and the transfer board member is attached to a second, distal end of the support arm 80, by a connection arrangement which allows the transfer board member 20 to pivot relative to the support arm and to be locked in position when desired, as will be described in detail below. Further, the arm can rotate about the axis of the post 40, and be locked against rotation when desired. Further, the height of the support arm 80 can be adjusted. Thus it will be appreciated that the post 40 is, in use, attached to a floor as a substantially permanent installation, while the transfer board member 20 is attached thereto in an adjustable and lockable manner which allows it to be positioned suitably to provide a stable and supported bridge between a wheelchair and a destination location, such as a toilet.

2018236806 27 Sep 2018 [00152] The transfer board member 20 is broadly in the shape of an elongate rectangle with rounded corners, and is, in use, supported (by the support arm 80) at a region substantially closer to one end thereof than to the other. The transfer board member 20 provides an upper surface 22 along which a user may effect transfer from a wheelchair, for example, onto a toilet. The transfer board member 20 may be formed from a suitable polymer/plastic. Adjacent at least one of the edges, and preferably at least an edge intended to be most accessible to a user during use, the transfer board member 20 is provided with a plurality of handles or grab-holds to facilitate use. In the illustrated embodiment, the handles are provided by recesses 24, 26, 28, which may extend through the entire thickness of the transfer board member 20. For ease of use, each of the recesses is sized to allow the surrounding material, and in particular the material at the periphery of the transfer board member 20 which is bounded by the recesses, to be securely gripped. For example, the recesses may be at least 10 cm long and at least 5 cm wide. The handles may have similar cross sectional size and shape to well-known handles as provided on tools, sports racquets and like equipment. The recesses may be formed during moulding of the transfer board member 20.

[00153] The underside of the transfer board member 20 may be provided with configurations to assist attachment to a support structure. Figure 4 shows two mounting recesses 30 which will be described in due course.

[00154] The post 40 comprises lower post portion 42 and an upper post portion 62 connected to the lower post portion 42. The lower post portion 42 is adapted to be securely attached to a floor, and is provided with a base flange 43 at the bottom thereof. The base flange 43 is provided with a plurality of apertures 44 therethrough for receiving bolts (not shown) or other suitable fixings, for securely attaching the base flange 43 and lower post portion 42 as a whole, to a floor. A flange for use with four or five bolts (or other suitable fixings) can provide a secure fixing and ease of installation.

[00155] The lower post portion 42 further comprises a generally cylindrical lower post body 45, which extends substantially upwardly from the base flange 43, and is securely and fixedly attached thereto.

[00156] In use, the lower post portion 42 is securely attached to a floor at a desired position adjacent a destination location to which a wheelchair user is to be transferred.

[00157] The upper post portion 62 is coaxial with the lower post portion 42, and is attached thereto via a post connection arrangement 55 which allows lockable rotation of the upper post portion 62 about the common (vertical) axis, relative to the lower post portion 42. Further, the

2018236806 27 Sep 2018 post connection arrangement 55 allows the height of the upper post portion 62 to be varied. It will be appreciated that Figure 1 illustrates the upper post portion 62 at a lesser height and Figure 2 shows the upper post portion 62 at a greater height. The post connection arrangement 55 will be described in more detail in due course, with reference to Figure 4.

[00158] The upper post portion 62 is provided with the support arm 80 connected thereto, and extending substantially perpendicular to the axis of the post 40. The upper post portion 62 comprises a generally cylindrical upwardly extending upper post body 64. The upper post portion 62 is further provided with a locking handle 66 for operation by a user to lock or unlock the rotation of the upper post portion 62 relative to the lower post portion 42.

[00159] A proximal end 82 of the support arm 80 is attached the upper post portion 62. The support arm 80 extends away from the upper post portion 62, substantially perpendicular thereto. In this embodiment, the support arm 80 is provided with a bend or curve 84 of approximately 90 degrees.

[00160] The distal end 86 of the support arm 80 is connected to the transfer board member 20 by a transfer board connection arrangement 90 which allows pivotal movement of the transfer board member relative to the support arm 80.

[00161] The post connection arrangement 55 and board connection arrangement 90 will now be described in more detail with reference to Figure 4. Part of the post connection arrangement 55 is shown in enlarged view in Figure 5.

[00162] The post connection arrangement 55 comprises an inner sleeve 56 which is able to fit substantially entirely within the lower post body 45 to provide a lower height for the extend upper post portion 62 or to extend upwardly out of the lower post body 45 to provide a greater height for the upper post portion 62. The inner sleeve 56 is constrained so that it can move axially, but not rotate, relative to the lower post body 45. In an embodiment, axially extending grooves (not shown) are provided on an interior surface of the lower post body 45, and axially extending ridges (not shown) are provided on an exterior surface of the inner sleeve 56, so that engagement of the axially extending ridges within the axially extending grooves allows relative axial but, not rotational, movement. The inner sleeve 56 may be biased upwardly by suitable means, such as one or more springs or gas struts (not shown), to facilitate height adjustment by a user. Suitable stops are provided to limit axial movement of the inner sleeve 56 relative to the lower post body 45, for example, by suitable termination of the grooves.

[00163] The post connection arrangement 55 further comprises a first toothed ring 57, with upwardly projecting teeth, fixed to the upper end of the inner sleeve 56, and coaxial with the

2018236806 27 Sep 2018 inner sleeve 56. Thus it will be appreciated that the first toothed ring 57 cannot rotate relative to the lower post body 45. The post connection arrangement 55 further comprises a second toothed ring 58, with downwardly projecting teeth, set within the bottom end of the upper post portion 62 so that it can move axially relative to the upper post portion 62 but cannot rotate relative to the upper post portion 62. The bottom end of the upper post portion 62 is journaled to the upper end of the inner sleeve 56 so that the upper post portion 62 can rotate relative to the lower post body 45 unless locked against such rotation. The upper post portion 62 can be locked against rotation relative to the lower post body 45 by engaging the first and second toothed rings 57, 58 together so that the teeth mesh. This prevents relative rotation of the first and second toothed rings 57, 58 and thus prevents rotation of the upper post portion 62 relative to the lower post body 45.

[00164] The first and second toothed rings 57, 58 can be brought into engagement, and disengaged when desired, by operation of the locking handle 66, as foreshadowed above. The locking handle 66 is rotatable and is connected to a threaded shaft (not shown) which is coaxial with the post 40 and which passes through a complementary female threaded opening in the second toothed ring 58. Thus rotation of the handle 66 causes the second toothed ring 58 to be moved axially, effecting engagement or disengagement with the first toothed ring 57. Providing a large number of teeth (at least about 24) on each ring allows a secure lock to be achieved in any of a wide range of rotational positions, enabling users to configure their transfer approach as desired. The thread of the threaded shaft is selected with a small or fine pitch to provide a large mechanical advantage, assisting wheelchair users who may have impaired strength. Further, the handle 66 is large to facilitate grip and provide mechanical advantage.

[00165] Various shims, sleeves and couplings between the parts may be included as desired or necessary to enhance fitting or function. In the illustrated embodiment, as can be seen in Figure 4, the coupling of the handle 66 to the upper post portion 62 is facilitated by a handle insert 67, and the coupling of the inner sleeve 56 to the lower post body 45 is facilitated by a sleeve guide 59.

[00166] As can be seen in Figure 4, the transfer board connection arrangement 90, which allows pivotal movement of the transfer board member 20 relative to the support arm 80, comprises a flanged collar 92 which fits securely in the distal end 86 of the support arm 80, and a mounting element 93 securely connected to the transfer board member 20. In the illustrated embodiment, the mounting element is in the form of a mounting block, part of which fits within a recess 30 on the underside of the transfer board member 20. Screws or bolts (not shown) secure the connection. The flanged collar 92 and mounting element 93 are connected by a threaded shaft 94 which is attached to the flanged collar 92 and which passes through the mounting

2018236806 27 Sep 2018 element 93, and upon which a tightening end-nut or end-cap 95. Tightening the endcap 95 effectively locks the connection arrangement 90 against rotation.

[00167] Figures 6 to 8 are illustrations of the embodiment of Figures 1 to 5 positioned as a permanent installation, adjacent a particular destination location, in this case, a toilet 99. Figure 9 is a schematic illustration of the embodiment of Figures 1 to 5 in use.

[00168] It will be appreciated that this and other embodiments could be used in relation to other destination locations, such as suitable baths, beds, showers, or adjacent a parking location for a vehicle to assist transfer thereto.

[00169] It will be appreciated that any suitable materials could be used for the parts described above. In a particular embodiment, it is considered beneficial to have the transfer board member 20 and the locking handle 66 made of high density polyethylene, and the lower and upper post portions 42, 62 and arm 80 made from stainless steel (for example, grade 304L). These materials provide reasonable cost, ease of manufacture, robustness, durability and hygiene. Sorrento Blue High Density Polyethylene (HDPE) is considered to provide a colour luminance contrast of 30% to meet the regulations outlined in Australian Standard (AS) 1428.1.

[00170] The intention is that a transfer apparatus in accordance with the present disclosure would be retrofitted into public (and other) toilets to facilitate wheelchair to toilet transfers. This would reduce the need to carry a transfer board, reduce the difficulty of needing to use a toilet in the event that a portable transfer board was mislaid or forgotten, and because of the increased stability may in many cases allow a wheelchair user who would otherwise require assistance to perform the transfer in a self-sufficient, yet safe, manner.

[00171] People who will use the transfer apparatus will have a wide spectrum of physical capabilities. This spectrum will range from low level spinal injuries which indicate paralysis below the waistline, through to users who require carer assistance. Those who have a mid to high level spinal injury which results in restricted hand movement and severely reduced core strength who currently have restricted independence, are expected to find particular benefit in enhanced ease of use and stability associated with the described embodiment.

[00172] Use of the transfer apparatus in accordance with the present disclosure may therefore assist in restoring dignity to those previously embarrassed or encumbered due to the transfer process, and removing the need for wheelchair users to carry a portable transfer board with them in public spaces.

2018236806 27 Sep 2018 [00173] This embodiment is considered to be a convenient, structurally simple, robust and cost effective solution to meet the needs of wheelchair users across Australia, and likely elsewhere. The height adjustment and rotation allows the apparatus to cater for wheelchairs of a wide range of sizes and shapes. The facility to move the transfer board member 20 into the desired position, and then lock it against movement while it is supported by a fixed, secure structure offers a transfer platform with stability, security and safety that is often considered missing from known portable transfer boards.

[00174] Carrying portable transfer boards is regarded by many users as an unhygienic and/or cumbersome task. In addition, transfers are often fraught with danger as boards can slip and users can fall with no easy means of getting back onto their chair. In contrast, the described embodiment, using a fixed bollard/post as a support, is considered to help provide a safe and secure transfer for wheelchair users as the locking mechanisms ensures that the board cannot slip (for example, from the wheelchair or the toilet).

[00175] Figures 10 to 19 illustrate an alternative embodiment, generally designated 100.

[00176] Rather than supporting a transfer board member on a single post or bollard, the transfer apparatus 100 supports a transfer board member on a support in the form of a rail.

[00177] Another difference is the shape of the transfer board member 120 that is formed with a number of large finger like projections 125, 126, 127. The recesses 128, 129 between the projections may receive part of wheelchair and which may help avoid inadvertent movement of the wheelchair during the transfer.

[00178] The rail 140 is horizontal and is supported on first and second legs 142, 144. The rail 140 is mounted to the legs 142, 144 through respective end caps 146, 148. As seen in Figure 13, the end caps 146,148 have mounting projections 146a, 146b; 148a, 148b for locating within the open ends 140a, 140b of the rail and legs 142a, 144a. The projections 146a, 146b; 148a, 148b have a profile with recesses and a groove that are complementary to the inner profile of the rail 140 and legs 142, 144 to assist in guiding thereon. Each leg 142, 144 has afoot 142f, 144f welded thereon and the legs 142,144 are bolted to a support surface such as a floor through apertures 150 in each foot 142f, 144f.

[00179] The profile of the open ends140a, 140b of the rail are the same profile as that of the legs 142, 144. This means that the end caps 146, 148 may be connected in any orientation. This assists in economics of construction and ease of installation.

2018236806 27 Sep 2018 [00180] The transfer apparatus 100 may be easily installed onto a support surface. The transfer apparatus 100 may be provided in a partially unassembled form comprising the rail 140 preassembled with the transfer board member 120 slidably mounted thereto; first and second legs 142, 144 and first and second end caps146, 148. In a first step, bolt holes are drilled in the floor at the desired locations. The first end cap 146 is bolted to a first end 140a of the rail 140, followed by the second end cap 148 bolted to the opposite end 140b of the rail 140. The respective legs 142, 144 are then bolted to the respective end caps 146, 148. The assembled transfer apparatus 100 is then bolted to the predrilled holes in the floor.

[00181] The transfer board member 120 is carried by a carriage or dolly 180 that is slidably mounted to rail 140. The rail 140 is oval in cross section and the carriage 180 surrounds and engages the rail 140. The rail 140 and carriage 180 are configured such that the carriage 180 cannot rotate about the rail 140.

[00182] Figures 14a and 14b show perspective and end views of carriage 180. The carriage 180 has a J shaped cross section. The base 160b of the J has a curvature complementary to the base 140b of the rail 140. The end of the J terminates in a horizontal section 162 and a plate 164 having an upstanding part and a depending part. The horizontal section 162 extends through and rests on a slot 166 running along the outside of the rail 140 such that the plate 164 locates in the internal space of the rail 140 as shown in figure 14c. In use, when there is no load on the transfer board member 120 the horizontal section 162 easily slides along the lower surface of the slot 166. However, when under a load such as during a transfer the weight of the user will effectively “lock” the carriage 180 from sliding along the rail.

[00183] The upper part of the carriage 180 is provided with first and second spaced cylindrical mounting members 190a, 190b. A first cylindrical mounting member 190a has friction teeth 191 mounted onto or formed thereon.

[00184] Figure 15a shows the underside of the transfer board member 20 and illustrates how the transfer board member 120 is mounted to the carriage 180. The carriage 180 is slidably mounted on rail 140. The transfer board member 120 is fixed to a support plate 192. The support plate 192 has spaced cylindrical mounting members 192a, 192b that are shown on either side of the carriage mounting members 190a, 190b. The support plate 192 and transfer board member 120 that is mounted thereto is pivotally mounted to the carriage 140 by a pivot member 196 passing through each of the respective mounting members of the support plate 192 and the carriage 180.

2018236806 27 Sep 2018 [00185] The pivot member 196 has a handle 194 connected thereto. A support member 170 is fixedly mounted to the pivot member 196 and is located in the space 172 intermediate the two carriage mounting members 190a, 190b. The support member 170 has an extending support tab 174 and a ring of friction teeth 176. This is shown in more detail in Figure 15c.

[00186] The transfer apparatus 100 has an unlocked configuration in which the support plate 192 and fixed transfer board member 120 may be freely pivoted about the pivot member 196 to a desired angle and height for patient transfer. Figures 15a and 15b show the apparatus 100 in the unlocked configuration. In order to move the apparatus 100 to a configuration in which the apparatus 100 is locked against pivotal movement of the transfer board member 120, the handle 194 is turned anti-clockwise until the support member 170 abuts the lower surface of the support plate 192. The handle 194 is pushed inwards until the friction teeth 176 of the support member 170 engage the friction teeth 191 on the carriage 180. This frictional engagement locks against rotation.

[00187] In order to unlock the apparatus, the handle 194 is simply withdrawn to disengage the respective friction teeth 176, 191. A stop 178 is provided at the end of the pivot member 196 to prevent withdrawal of the pivot member 196 from the carriage 180.

[00188] To use, the apparatus for a transfer the carriage 180 is first slid along rail 140 to a desired location on the rail. A part of the wheelchair may be located in one of the recesses 12, 129 so as to avoid inadvertent movement of the wheelchair and also allow the person a more favourable position relative to the toilet for transfer. The transfer board member 20 is then pivoted to the desired position and locked into position as discussed above for transfer.

[00189] Providing a rail which extends along and/or at least partially around the destination location may facilitate a wide range of transfers that include, but are not limited to, front transfers and side transfers. The apparatus 100 may assist the visually impaired, the elderly and people with spinal injuries who are wheelchair bound. The apparatus 100 is well adapted to retrofitting into any Australian Standard accessible toilet, regardless of the toilet’s position. The rail may be modular, as illustrated in Figure 13, and different lengths, heights and curvatures may be provided.

[00190] Figures 20 to 25 illustrate a further embodiment of a transfer apparatus 200. Figure 20 shows the transfer apparatus 200 in use. It may be seen that the transfer apparatus 200 is located between a wheelchair 202 and a toilet 204. The transfer apparatus 200 has a box-like support 230 that is fixed to the floor. A first transfer board member 222 extends from the support 230 to the toilet and the peripheral edge 232 that rests on the edge of the toilet seat. The

2018236806 27 Sep 2018 peripheral edge 232 is concave and complementary to the toilet seat. This means that the transfer board member 222 does not come into contact with the user when they are using the toilet.

[00191] The second transfer board member 220 extends from the support 230 to a wheelchair upon which it rests. The second transfer board member 220 has a fin like shape with a convex forward surface edge and a concave rearward edge. This can facilitate ease the transfer apparatus 200of use for a person to slide across the transfer apparatus 200. The second transfer board member 220 has an aperture 224 towards the peripheral edge that in use may be used as a handle.

[00192] The components of the transfer apparatus will be further described with reference to Figures 21 to 25.

[00193] The support 230 is fixed to the floor by means of a U shaped base 240 as shown in Figure 22. The base has two upstanding arms 240a, 240b and an interconnecting web 242. The web 242 has four bolt receiving apertures 244 for bolting the base to a support surface such as a floor. Each arm 240a, 240b has two apertures 246 for receiving a bolt or other fixing device.

[00194] The support 230 is shown in Figure 23 and has a support body defined by side walls 230s, end walls 230e and a base 230b. The end walls 230e each have a series of vertically spaced pairs of apertures 232. The support 230 is fixed to the base 240 by aligning a selected aperture pair 232 with the apertures 244 in the base 240. In this way, the height of the apparatus can be varied to suit toilets of different heights. The apparatus 200 may also be fixed adjacent other destination locations such as a bath or bath chair.

[00195] A hinge assembly 260 is shown in figures 24 and 25. The hinge assembly 260 is mounted to the top of the box-like support 230. The hinge arrangement 260 comprises first and second hinge members 262, 264. Two hinge pins 270, 272 extend between the hinge members 262, 264.

[00196] Each hinge member 262, 264 has a flat top section 266 an end 268 and two legs 267 depending from the end. Each leg 267 has an upwardly open recess 269.

[00197] The respective transfer board members 220, 222, are pivotally mounted on the pins 270, 272 for pivotal motion between an in use position in which they extend broadly horizontally from the support and a non-use position in which case the transfer board members are received substantially vertically within the support member 230.

2018236806 27 Sep 2018 [00198] As may be seen in Figure 25, each transfer board member 220, 222 has an inwardly extending tongue 280, 282 with apertures 284, 286 for receiving the respective hinge pin 270, 272. In this way, when in the in use position, the inner edges of the tongues are close together with only a small gap therebetween. It may be seen from Figures 20 and 21 that the tops 266, 268 of the hinge members 262, 264 are flush with the transfer board members 220, 222. This arrangement of parts provides a smooth transfer surface for a user.

[00199] The hinge assembly 260 is slidably received within the support 230 for movement between the in-use positions illustrated in Figures 20 and 21, and a non-use (or storage) position in which the hinge assembly 260 fits against the base 238 of the support 230 and the attached transfer board members 220, 222 extend vertically upwards and are housed within the support 230. The handle part 224 of the second transfer board member 220 is upper most and can be used by a user to pull up the transfer boards and hinge assembly. The respective internal ends of the support body 230 each define tracks 239 for the legs 267 of hinge members 262, 264.

[00200] Rubber stoppers (not shown) are provided at the base of the body to protect the inner edges of the transfer board members 220, 222 from hitting the base of the support 230b and becoming damaged.

[00201] Stops, that in an embodiment may be grub screws, are mounted to the upper parts of the track and extend into the track path. When the hinge assembly is being pulled upwards, in the embodiment where the stops are grub screws, the heads of the grub screws are received within the respective recesses 272 of the legs 267 of the hinge members. This prevents the hinge assembly 260 from being pulled out of the support body 230.

[00202] Suitably the stops may be easily removed to allow the hinge assembly 260 and attached transfer board members 220, 222 to be removed from the support 230 body for maintenance or repair.

[00203] When the hinge assembly 260 is in the uppermost position, the transfer board members 220, 222 will pivot outwards into an effective cantilever position and their weight will keep the hinge assembly 260 at the top of the support 230.

[00204] An advantage of this embodiment is that the apparatus 200, when in the non-use position, is compact in size and may be used for locations where space is limited such as toilet cubicles that are not dedicated wheelchair cubicles and toilet cubicles on air planes, trains and the like. The apparatus 200 may also be installed in a domestic environment where a toilet cubicle is shared with ambulatory persons.

2018236806 27 Sep 2018 [00205] The apparatus 200 may be easily converted to the in use position by pulling upwards using aperture 224 in the second transfer board member 220. As the second transfer board member 220 can pivot upwards when in the in-use position, wheelchairs of different heights can be accommodated. The region of the of the second transfer board member 220 distal from the support rests on the seat of a wheelchair as shown in Figure 20. The convex edge may help avoid interference with an arm or wheel of the wheelchair. After transfer back to the wheelchair, the user simply returns the apparatus 200 to the non-use position by lifting the second transfer board member 220 using handle and to a vertical position that allows the hinge assembly and transfer boards to recess into the support body to the non-use position.

[00206] Figures 26 to 43 illustrate an alternative embodiment of a transfer apparatus, generally designated 2600, related to the transfer apparatus 10 of Figures 1 to 9. The transfer apparatus 2600 has similarities to the transfer apparatus 10, which will be evident from Figures 26 to 43, and the following description therefore refers to the transfer apparatus 10 and focuses on differences between the transfer apparatus 2600 and the transfer apparatus 10. The transfer apparatus 2600 is intended to provide an alternative to the transfer apparatus 10 which is simpler and more economical in construction.

[00207] The transfer apparatus comprises a post 2640 which (unlike the post 40 of transfer apparatus 10) includes a horizontally extending upper arm portion 2660 which is fixed in position relative to the rest of the post 2640. A connection arrangement 2690 between the transfer board member 2620 (similar to the transfer board member 20 of transfer apparatus 10) and the upper arm portion 2660 allows the transfer board member 2620 to be moved between a storage position, illustrated in Figures 26 to 28, and a working position, illustrated in Figures 34 to 36, without disconnection from the post 2640, and so that in the working position the support provided to the transfer board member 2620 by its connection to the post enhances stability of the transfer board member 2620 during transfer.

[00208] The connection arrangement 2690 comprises a first connection element 2693 which can rotate or pivot about the generally horizontal axis of the upper arm portion 2660 of the post 2640. The connection arrangement 2690 further comprises a second connection element 2696 which is in use attached to the first connection element 2693 so that it can rotate relative thereto, and is substantially fixedly connected to the transfer board member 2620. The first and second connection elements are most clearly illustrated in Figures 38 to 43.

[00209] In the illustrated embodiment, the first connection element 2693 comprises a collar part 2694A which provides a generally cylindrical cavity 2694C which in use accommodates and engages part of the upper arm portion 2660 of the post 2640. That is, the collar part 2694A

2018236806 27 Sep 2018 extends around and closely engages the upper arm portion 2660 of the post 2640 so that it may pivot about the axis of the upper arm portion 2660, which is also the axis of the generally cylindrical cavity 2694C of the collar part 2694A. The collar part 2694A may be retained on a terminal or end region of the upper arm portion 2660 of the post 2640 by an end plate 2695.

[00210] The first connection element 2693 further comprises a swivel arm outer member 2694B which is generally cylindrical and tubular in form (shown partially cut-away in Figure 38) and which is rigidly attached to the collar part 2694A so that its axis of elongation is substantially perpendicular to the axis of the generally cylindrical cavity of the collar part 2694A.

[00211] The second connection element 2696 comprises a flange 2697 for attachment to the transfer board member 2620, and a swivel arm inner member 2698 which extends substantially perpendicularly from the flange 2697. In the illustrated embodiment, the swivel arm inner member 2698 is generally cylindrical and tubular in form. In use, the swivel arm outer member 2694B snuggly accommodates the swivel arm inner member 2698, as illustrated in Figures 38 to 43, to allow rotation of the swivel arm inner member 2698 relative to the swivel arm outer member 2694B, about the shared axis thereof, thus allowing the transfer board member 2620 to swivel or rotate relative to the first connection element 2693.

[00212] In the illustrated embodiment, the rotation of the swivel arm inner member 2698 relative to the swivel arm outer member 2694B is constrained to about a quarter rotation (about 90 degrees) and a locking arrangement 3800 is provided to selectively lock the swivel arm inner member 2698 against rotation relative to the swivel arm outer member 2694B at a first terminus of the rotation, corresponding to a storage configuration, or at a second opposite terminus of the rotation, corresponding to a working configuration.

[00213] Although any desired and practicable locking arrangement 3800 could be used, in the illustrated embodiment, the locking arrangement 3800 comprises a biased locking pin 3810.

[00214] Figures 38 and 39 are schematic exploded views of an embodiment of a locking arrangement 3800, including a locking pin 3810, and also showing detail of the first connection element 2693, including the swivel arm outer member 2694B, and of the second connection element 2696 including the swivel arm inner member 2698.

[00215] In the illustrated embodiment, the locking pin 3810 has a first end part 3812, which is, in use, retained within swivel arm inner member 2698. The locking pin 3810 has an intermediate diameter part 3814 adjacent the first end part 3812, which extends a length along the locking pin 3810, and a reduced diameter part 3816 at the end of the intermediate diameter part which is distal from the first end part 3812. The reduced diameter part 3816 is axially short

2018236806 27 Sep 2018 and terminates at its end distal from the intermediate diameter part 3816, in a part 3815 of the locking pin which is of greater transverse size (e.g. greater diameter) than the intermediate diameter part 3814. The rest of the locking pin, including a handle region 3817 at or adjacent a second end part 3818 thereof, may also greater diameter than the intermediate diameter part 3814.

[00216] The swivel arm inner member 2698 is provided with an aperture 3820, with diameter corresponding substantially to the diameter of the intermediate diameter part 3814 of the locking pin 3810, in which the intermediate diameter part 3814 of the locking pin 3810 can be received. The first end part 3812 of the locking pin is retained within the swivel arm inner member 2698 by a fastener 3822 (such as a washer or circlip attached to the first end part 3812). The locking pin 3810 is biased outwardly, for example, by a helical spring 3824 attached to the fastener 3822 and to the inner wall of the swivel arm inner member 2698 adjacent the aperture 3820, and adapted to resist extension (illustrated in Figures 41 (a) and 41 (b)) thereby providing an outwards bias force on the locking pin 3810 when the locking pin is forced inwardly relative to the swivel arm inner member 2698.

[00217] The swivel arm outer member 2694B is provided with a groove or elongate aperture 3830 which extends in a transverse plane of the swivel arm outer member 2694B, in this embodiment, about an angular extent of approximately 90 degrees. The elongate aperture 3830 is of sufficient width to allow the reduced diameter part 3816 of the locking pin to slide within it, but insufficient width to allow the intermediate diameter part 3814 of the locking pin 3810 to slide within it. The first and second ends of the elongate aperture 3830 widen to respective first and second greater width regions 3832, 3834, which are just wide enough to accommodate the intermediate diameter part 3814 of the locking pin 3810.

[00218] Figures 40(a) and 40(b) illustrate the locking mechanism of Figures 38 and 39, locked in a storage configuration, in which the intermediate diameter part 3814 of the locking pin 3810 is located in the first greater width region 3832. The swivel arm inner member 2698 cannot rotate relative to the swivel arm outer member 2694B because the intermediate diameter part 3814 of the locking pin 3810 cannot be moved into the elongate aperture 3830.

[00219] However, as illustrated in Figures 41(a) and 41(b), if the locking pin 3810 is pushed inwardly, that is, further into the interior of the swivel arm inner member 2698 against the bias force of the helical spring 3824, the reduced diameter part 3816 of the locking pin 3810 aligns with the elongate aperture 3830, and the swivel arm inner member 2698 can rotate relative to the swivel arm outer member 2694B moving the reduced diameter part 3816 within and along the elongate aperture 3830.

2018236806 27 Sep 2018 [00220] When the locking pin 3810 is moved all the way along the elongate aperture 3830, it reaches the second greater width region 3834, and the bias force pushes the locking pin 3810 outwardly so that the intermediate diameter part 3814 is pushed into the second greater width region 3834, effectively preventing rotation of the swivel arm inner member 2698 relative to the swivel arm outer member 2694B, and locking the connection arrangement in a working configuration, as illustrated in Figures 42 and 43.

[00221] Bearing in mind operation of the locking arrangement, Figures 26 to 37 illustrate configurations and positions of the transfer apparatus 2600 as a whole.

[00222] Figures 26, 27 and 28 illustrate the transfer apparatus 2600, in a storage position. The first connection element 2693 is at an extreme of its rotation (in the anti-clockwise direction, as viewed in Figures 26 and 27), which may be defined by stops or the like (not shown) in the engaging parts of the collar part 2694A and upper arm portion 2660 of the post 2640, and so that the swivel arm inner member 2698 and swivel arm outer member 2694B are both substantially horizontal. The locking arrangement 3800, is locked with the locking pin 3810 retained in the first greater width region 3832, corresponding to a storage configuration, as illustrated in Figure 29.

[00223] Figures 30, 31 and 32 illustrate the transfer apparatus 2600, part way through deployment to a working position, in that the locking arrangement 3800 has been operated and the transfer board member 2620 rotated by ninety degrees about the axis of the swivel arm inner member 2698 and swivel arm outer member 2694B. As described above, this is achieved by pushing in the locking pin 3810, and rotating the transfer board member 2620 until the locking pin reaches the second greater width region 3834 and is pushed outwardly by the spring to and lock the swivel arm inner member 2698 against rotation relative to the swivel arm outer member 2694B, as illustrated in Figure 33.

[00224] At this stage, and as illustrated in Figures 34, 35 and 36, the transfer board member 2620 can be rotated about the substantially horizontal axis of the upper arm portion 2660 of the post 2640 to place the transfer board member 2620 into a working position. More specifically, an end 2622 of the transfer board member 2620 which is distal from the toilet 99 (or other target destination) can be raised until it is at the height required for it to be placed upon and supported by a seat (or other supporting part, if desired) of a wheelchair.

[00225] It will be appreciated that, in this embodiment, there is no arrangement for locking the rotation of the collar part 2694A of the first connection element 2693 relative to the upper arm portion 2660 of the post 2640 (although, of course, such a locking mechanism could be

2018236806 27 Sep 2018 incorporated, if desired, in any suitable manner). This results in the transfer board member 2620 being moveable into its working position, supported by a wheelchair, and then used without requiring a further locking step to be performed by a user. Further, the transfer board member 2620 is considered to be stabilised during transfer, by being constrained by the rest of the transfer apparatus 2600, against tipping forwardly (i.e. about an axis parallel with the longitudinal direction of the transfer board member 2620) and against horizontal movement (for example, sliding forwardly or sideways off of the wheelchair).

[00226] Figures 44 to 56 illustrate an alternative embodiment of a transfer apparatus, generally designated 4400, related to the transfer apparatus 100 of Figures 10 to 19. The transfer apparatus 4400 has similarities to the transfer apparatus 100, which will be evident from Figures 44 to 56, and the following description therefore refers to the transfer apparatus 100 and focuses on differences between the transfer apparatus 4400 and the transfer apparatus 100. The transfer apparatus 4400 is intended to provide an alternative to the transfer apparatus 100.

[00227] One difference between the transfer apparatus 4400 and the transfer apparatus 100 is that the transfer apparatus 4400 provides a transfer board member 4420 which does not provide elongate finger like projections (126, 126, 127 in transfer apparatus 100) but rather provides relatively short and broad projections 4421, which are easier to provide with the structural strength required. In the illustrated embodiment, the transfer board member 4420 is made in a shape which represents a stylised animal face, which may help make transfers a more enjoyable and fun experience, especially for younger users.

[00228] Figure 44 is a schematic exploded view of transfer apparatus 4400, illustrating the main components. The transfer apparatus 4400 provides a rail in the form of a rail arrangement 4440 which provides an upper rail 4450, and a lower rail 4460. The rail arrangement is also illustrated in detail, in vertical transverse cross section, in Figure 47. Like the rail 140 of transfer apparatus 100, the rail arrangement 4440 may extend at least partially around a toilet or other destination location to allow transfers from different positions, such as side transfers and front transfers. A rail arrangement cover plate 4470 extends between the upper rail 4450 and the lower rail 4460 along the outer lateral side of the rail arrangement. A rail arrangement inner plate 4475 is attached to, and extends slightly downwardly from, the lower rail 4460, extending along the inner lateral side of the rail arrangement. The rail arrangement 4440 is supported by legs 4442 and includes mounting plates 4446 for securing to a wall.

[00229] First and second main dollies or carriages 4480, 4480A can move linearly along the rail arrangement 4440. The carriages 4480, 4480A are slightly spaced apart, and support a transfer board member 4420, so that the transfer board member 4420 can be moved along and

2018236806 27 Sep 2018 around the rail arrangement 4440. The transfer board member 4420 is attached to a hinge arrangement 4496, which is mounted via respective swivel plates 4498, 4498A to the upper parts of the carriages 4480, 4480A. The use of swivel plates 4498, 4498A assists navigation of the carriages 4480, 4480A and the transfer board member 4420 around corners or curved parts of the rail arrangement 4440.

[00230] The transfer apparatus 4400 may also include a further, subsidiary, dolly or carriage 4490, which supports an extensible strut 4492 which is attached to, and offers support to, a front region of the transfer board member 4420, being a region which is distal from the destination location (for example, a toilet). In the illustrated embodiment, a first end 4493 of the extensible strut 4492 is attached to the subsidiary carriage 4490 via a pivoting connection 4494, and a second end 4495 of the extensible strut 4492 is attached to the front region of the transfer board member 4420 via a pivoting connection 4496 and a mounting plate 4497.

[00231] An end region 4447 of the rail arrangement 4440 may provide one or both of the upper rail 4450 and lower rail 4460 (and, if desired, other parts of the rail arrangement) with reduced transverse size, and/or may provide removable rail and/or other parts of the rail arrangement to facilitate attachment and detachment of the carriages 4480, 4480A, 4490 to the rail arrangement for assembly, maintenance, replacement and the like.

[00232] Figure 45 and 46 illustrate the structure of the main carriages 4480, 4480A, with reference to first main carriage 4480. It should be appreciated that second main carriage 4480A is substantially identical in the illustrated embodiment.

[00233] First main carriage 4480 comprises a first roller 4481 with a concave engagement surface 4481A for engagement with a convex upper surface of upper rail 4450.

[00234] First main carriage 4480 further comprises a second roller 4482 with a concave engagement surface 4482A for engagement with a convex upper surface of lower rail 4460.

[00235] First main carriage 4480 is adapted to be linearly moveable along the rail arrangement 4440, by a user, by rotation of the rollers 4481, 4482, in engagement with the respective upper and lower rails 4450, 4460.

[00236] The first roller 4481 is mounted between, and to, opposed first and second side walls 4483, 4484 of the first main carriage 4480.

[00237] The first roller 4481 is adapted to be lockable against rotation to thereby substantially prevent (or lock) movement of the first main carriage 4480 relative to the rail arrangement 4440.

2018236806 27 Sep 2018 [00238] First main carriage 4480 includes a manually operable locking member 4485 adapted to lock the first roller against rotation.

[00239] In the illustrated embodiment, the manually operable locking member 4485 is moveable by and with a locking member pin 4485A which is mounted between, and to, the opposed first and second side walls 4483, 4484 of the first main carriage 4480, and which extends through the second side wall 4484, where it is connected to a locking handle 4485B. Manual movement of the locking handle 4485B, about the axis of the locking member pin 4485A can rotate the locking member 4485 between a locking position, in which it locks the first roller 4481 against rotation, and an unlocking position, in which it does not lock the first roller 4481 against rotation.

[00240] In the illustrated embodiment, the first roller 4481 is provided with a plurality of circumferentially arranged locking teeth or locking projections 4481B. In this embodiment, the locking position of the locking member 4485 corresponds to a position in which an engagement part of the locking member 4485 is located between at least two locking projections 4481B of the first roller 4481, to thereby obstruct rotation of the first roller 4481. Of course, other locking arrangements could be used if desired.

[00241] Each of the first and second side walls 4483, 4484 of the first main carriage 4480 has a lower terminus which provides a return portion to provide a recess or channel 4483A, 4484A for receiving a lower edge of the rail arrangement 4440 to assist in securing and guiding the first main carriage 4480 along the rail arrangement 4440.

[00242] Figure 46 illustrates schematically in partial transverse cross sectional view, the first main carriage 4480 engaged with the rail arrangement 4440, in use and adjacent a toilet 99.

[00243] Figure 47 illustrates schematically in transverse cross sectional view, the first main carriage 4480 next to the rail arrangement 4440, with some detail omitted, to provide additional clarity regarding certain features of each. It should be appreciated that, in use, the first roller

4481 engages the upper surface of the upper rail 4450, the second roller 4482 engages the upper surface of the lower rail 4460, the channel 4483A in the first side wall 4483 receives a lower edge 4477 of the inner plate 4475, and the channel 4484A in the second side wall 4484 receives a lower edge 4472 of the cover plate 4470.

[00244] It will be appreciated that the second roller 4482 is mounted to only the first side wall 4483 of the first main carriage 4480, in what may be regarded as a somewhat cantilever arrangement. This allows part of the cover plate 4470 to be located between the second roller

4482 and the second side wall 4484 of the first main carriage 4480, in use, which allows the

2018236806 27 Sep 2018 cover plate 4470 to provide a clean exterior surface and obscure the lower rail 4460, and the gap between the upper and lower rails 4450, 4460, from view.

[00245] The upper rail 4450, lower rail 4460 and cover plate 4470 may be regarded as together defining an interior hollow or cavity 4448 which the second roller 4482 is substantially located within, in use.

[00246] Figure 48 illustrates schematically, in partial transverse cross sectional view, the operation and structure of the subsidiary carriage 4490 and extensible strut 4492. The subsidiary carriage 4490 may be structured somewhat similarly to the man carriages, but is smaller in height, and does not extend upwardly to (and is not directly connected to) the hinge arrangement 4496. The subsidiary carriage 4490 provides only a single roller 4491 which, in use, engages the upper surface of the lower rail 4460. The extensible strut 4492 is connected to and, in use, supports a part of the transfer board member 4420 which is further from the destination location (e.g. toilet 99) than is the hinge arrangement 4496. The extensible strut 4492 has a minimum length, substantially as illustrated in Figure 48, adapted to allow the transfer board member 4420 to slope slightly downwardly from the hinge arrangement 4496 to its point of connection to the extensible strut 4492 (that is, in use, from the destination location to the wheelchair). The extensible strut 4492 is extensible so that the transfer board member 4420 can be rotated about the hinge arrangement 4496 to raise the front (or wheelchair engaging) side of the transfer board member 4420, but is not retractable to be shorter than the a length in which it supports the transfer board member in a slightly downwardly sloping orientation, as illustrated in Figure 48. The extensible strut 4492 can therefore provide support to the transfer board member 4420 in the event that it is inadvertently loaded without the front (or wheelchair engaging) side of the transfer board member 4420 being supported (e.g. by resting upon part of a wheelchair) and thus reduce the risk of a use falling and of damage to the transfer apparatus 4400.

[00247] Bearing in mind the structure described above, Figures 49 to 51 illustrate the transfer apparatus 4400 in a storage configuration; with the transfer board member 4420 and carriages 4480, 4480A, 4490 substantially at one end of the rail arrangement 4440 so that the toilet 99 can be used normally. Figure 49 is a perspective view, Figure 50 is a part cross sectional view through main carriage 4480A, and Figure 51 is a top plan view.

[00248] Figures 52 to 54 illustrate the apparatus 4400 part way through deployment to a working position wherein the transfer board member 4420 and carriages 4480, 4480A, 4490 have been moved along the rail arrangement 4440 to a position desired for transfer, but wherein the transfer board member 4420 is not yet supported by a wheelchair and, as shown, slopes

2018236806 27 Sep 2018 slightly downwardly from the hinge arrangement 4496 to its point of connection to the extensible strut 4492. Figure 52 is a perspective view, Figure 53 is a part cross sectional view through subsidiary carriage 4490A, and Figure 51 is a top plan view.

[00249] Figures 55 and 56 illustrate the transfer apparatus 4400 in a working configuration; with the transfer board member 4420 in a position corresponding to a front part thereof being supported by a wheelchair (although the wheelchair is not shown). As illustrated, the transfer board member 4420 slopes upwardly from the hinge arrangement 4496 to its point of support, e.g. 4425, by the wheelchair. The angle of slope will, of course, depend on the height (and to some extent position) of the wheelchair.

[00250] It will be appreciated that, in the working configuration the main carriages 4480, 4480A are locked in position relative to the rail arrangement 4440 restricting movement of the transfer board member 4420. Further, the transfer board member 4420 is constrained from tipping in a lateral direction by its connection to the main carriages 4480, 4480A. The transfer arrangement 4400 thus provides a transfer board member 4420 which is stabilised during transfer.

[00251] Figures 57 to 72 illustrate an alternative embodiment of a transfer apparatus, generally designated 5700, related to the transfer apparatus 200 of Figures 20 to 25. The transfer apparatus 5700 has similarities to the transfer apparatus 200, which will be evident from Figures 57 to 72, and the following description therefore refers to the transfer apparatus 200 and focusses on differences between the transfer apparatus 5700 and the transfer apparatus 200. The transfer apparatus 5700 is intended to provide an alternative to the transfer apparatus 200 which is simpler and more economical in construction.

[00252] Figure 57 is a schematic exploded view of the transfer apparatus 5700.

[00253] It will be appreciated that the transfer apparatus 5700 comprises a base 5740, corresponding generally in function and structure to the U shaped base 240 of transfer apparatus 200.

[00254] The transfer apparatus 5700 further comprises a box-like support 5730 corresponding generally in function to the box-like support 230 of transfer apparatus 200. However, it will be appreciated that the box-like support 5730 provides separately formed track members 5731, 5732, rather than providing tracks 239 (of transfer apparatus 200) which are integrally formed by the internal ends of the support 230.

2018236806 27 Sep 2018 [00255] The transfer apparatus 5700 further comprises first and second transfer board members 5720, 5722, connected by a hinge arrangement 5760, which correspond generally in function to the respective first and second transfer board members 220, 220 and hinge arrangement 260 of transfer apparatus 200. Similarly to the hinge arrangement 260, the hinge arrangement 5760 comprises first and second hinge members 5762, 5764, with first and second hinge pins 5770, 5772 extending therebetween, and the hinge pins 5770, 5772, in use extend through apertures 5784, 5786 which extend laterally through the respective first and second transfer board members 5720, 5722. The hinge members 5762, 5764 can be moved vertically, guided and constrained by the track members 5731, 5732, to operate the transfer apparatus 5700 between a storage configuration (illustrated in Figures 58 to 61) and a working configurations (illustrated in Figures 66 to 69).

[00256] Operational similarities between the transfer apparatus 5700 and the transfer apparatus 200 will be evident to the addressee.

[00257] However, in contrast to the transfer apparatus 200, in the transfer apparatus 5700 each of the first and second hinge members 5762, 5764 is provided with a wheel or roller 5763, 5765, which in use is constrained by a respective track member 5731, 5732.

[00258] Further, the box-like support 5730 provides top caps 5790, 5792, attached (for example, by bolts or screws) at the top and respective sides of the support 5730, which act as stops at the tops of the respective track members 5731, 5732, to constrain upwards movement of the hinge members 5762, 5764. (This is in contrast to the arrangement including grub screws described in relation to transfer apparatus 200.) Of course, other stop arrangements may alternatively or additionally be included.

[00259] Further, the box-like support 5730 provides a locking arrangement 5750, for securing the hinge members 5762, 5764 at the tops of the respective track members 5731, 5732, to thereby lock the transfer apparatus 5700 substantially in a working configuration. The locking arrangement 5750 comprises a manually operable member which, in this embodiment, is in the form of a locking pin 5751 which may be positioned to extend across a channel 5733 defined by one of the track members 5731, 5732 in order to prevent passage of a roller 5763, 5765 along the channel in a downwards direction. Operation of the locking arrangement 5750 is illustrated schematically in Figures 65, 69 and 70 to 72.

[00260] Figures 58 to 60 illustrate the transfer apparatus 5700 in a storage configuration, adjacent a toilet 99, with the first and second transfer board members 5720, 5722 substantially vertically orientated and mainly located within the box-like support 5730.

2018236806 27 Sep 2018 [00261] Figure 61 illustrates the relative positions, in the storage configuration of Figures 58 to 60, of the first and second transfer board members 5720, 5722 and the first hinge member 5762, the first hinge member being located substantially at the bottom of the channel 5733 defined by the first track member 5731.

[00262] Figures 62 to 64 illustrate the transfer apparatus 5700 part way through deployment to a working configuration, as the transfer board members 5720, 5722 (and, consequently, the hinge arrangement 5760) are being manually raised. The transfer board members 5720, 5722 are still substantially vertically orientated, but extend upwardly out of the box-like support 5730 substantially more than in the storage configuration of Figures 58 to 60.

[00263] With reference to Figure 65, an operational step in deploying the transfer apparatus 5700 from the storage configuration to the working configuration comprises moving the locking pin 5751, located near the top of channel 5733 defined by one of the track members 5731, so that it does not prevent passage of the roller 5763 to the top of the channel 5733. As illustrated, the locking pin 5751 is provided with a handle 5752. The locking pin 5751 can be moved (to the right, as illustrated in Figure 65) from a retracted position in which it extends across and obstructs the channel 5733 (as illustrated in Figure 69) to an extended position (illustrated in Figure 65) in which it does not extend across or obstruct the channel 5733 to allow passage of the roller 5763 and hinge arrangement 5760. It will be appreciated that Figures 62 and 64, as well as Figure 65, show the locking pin 5751 in the extended position in which it does not extend across or obstruct the channel 5733.

[00264] The locking pin 5751 is biased, by a spring or the like, to its retracted (locked) configuration, as illustrated schematically by helical spring 5753, arranged around part of the locking pin 5751. In an alternative configuration (not shown), for biasing the locking pin 5751 to its retracted (locked) configuration, a spring could be attached to the handle 5752 and to the wall of the support 5730, to bias the handle towards the support.

[00265] As illustrated, the locking pin 5751 is located in first and second apertures 5754A, 5754B on a first lateral side of the channel 5733, and may be inserted into (to provide the locked configuration) and withdrawn from first and (optionally) second apertures 5755A, 5755B on a second, opposite, side of the channel 5733.

[00266] Figures 66 to 68 illustrate the transfer apparatus 5700 in a working configuration. In the working configuration, the transfer board members 5720, 5722 are substantially outside the support 5730, and may be oriented substantially horizontally (as illustrated) or oriented by

2018236806 27 Sep 2018 rotation about the respective hinge pins 5770, 5772 of the hinge arrangement 5760 to an orientation suitable to rest on the wheelchair and on the toilet, respectively.

[00267] In the working configuration, as illustrated in Figure 69, the hinge members (e.g. hinge member 5762) are located substantially at the tops of the channels 5733, and the first hinge member 5762 is supported, and prevented from moving downwardly, by the locking pin 5751, which underlies the roller 5763.

[00268] Figures 70, 71 and 72 illustrate the positions of the hinge member 5762 and locking pin 5751 in, respectively, the storage, unpacking and working configurations.

[00269] The transfer apparatus 5700 is suitable for use in confined areas, and may also be provided as an apparatus which may be installed when needed (for example, when a hotel room and associated bathroom accommodate a wheelchair user) and removed from the site of use when not required. In such an embodiment, the base 5740 may be include a component of a bottom plate locking system adapted to lock to or be detached from, a complementary floor plate component of the bottom plate locking system which is permanently attached to the floor (of, for example, a bathroom). The apparatus apart from the floor plate could then be removed and, for example, stored in a cupboard when not required. In an embodiment, the floor plate component is located under a removable tile (smart tile) on the floor, enabling the bathroom to be restored to normal configuration and appearance when the apparatus is not installed for use.

[00270] At least some embodiments in accordance with the present disclosure provide definite working advantages over known portable transfer boards.

[00271] The stability associated with a transfer apparatus which has a support securely fixed to the floor and connected to a transfer board member so as to stabilise it during transfer can reduce the likelihood of falls and slipping-related injury during transfer.

[00272] They are anticipated to reduce the need, at least for some users, for transfer to be assisted by a carer.

[00273] Wide installation of the transfer apparatus, in accordance with the present disclosure, may reduce the need for wheelchair users to carry cumbersome transfer boards.

[00274] The provision of enhanced safety and independence may assist in restoring dignity to those who suffer the indignity of assisted transfers and/or falls during transfer.

[00275] They may allow access (for example, to a toilet) for wheelchair users without a portable transfer board or carer, who might otherwise be unable to gain access.

2018236806 27 Sep 2018 [00276] Further, embodiments are relatively straightforward to retrofit into Australian public toilets to facilitate wheelchair to toilet transfers.

[00277] Compared to provision of shared portable transfer boards, they are less susceptible to theft and/or malicious removal or damage.

[00278] Of course, the above features or functionalities described in relation to the embodiments are provided by way of example only. Modifications and improvements may be incorporated without departing from the scope of the invention.
