Description

[0001] This invention relates to transfer plates, and more particularly to toilet transfer plates for supporting a person during transfer between a wheelchair, chair, bed or similar surface and a toilet or commode.

[0002] A "toilet" is generally considered a permanent fixture, typically found in a bathroom. A "toilet seat" is typically a portable toilet that can be moved or placed in various locations, usually for users with limited mobility. Embodiments of the present invention can be used with both toilets and toilet seats, and in the context of this specification, the term "toilet" includes toilet seats.

[0003] For individuals with mobility impairments, transferring to a toilet or commode can be challenging. They need to feel stable and comfortable both when entering and exiting the seat throughout the transfer. For many, caregiver assistance is required. This hinders the shared desire to live as independently as possible and without dependence on others.

[0004] For example, individuals who cannot safely transfer from bed to the commode at night may need to wear incontinence pants or sleep on incontinence sheets for toileting purposes. Contact with these damp and wrinkled incontinence pads or sheets can cause skin breakdown, potentially leading to pressure sores and open wounds. The necessity of using incontinence pads and sheets does not enhance an individual's dignity.

[0005] However, another option for incontinence pads is to use the toilet, which can cause many problems for people with mobility issues, especially at night.

[0006] Typically, when transferring from a wheelchair, the user or their caregiver must attempt to maneuver the wheelchair as close as possible to the toilet or commode chair, ideally backing into a position next to the seat. Their mobility issues may lead them to prefer transferring from the left side of the toilet or commode chair, or in other cases, from the right. Alternatively, some users may be able to transfer from the front of the toilet. However, there may also be other objects near the toilet that obstruct movement and may prove difficult to get close to. Toilets are fixed to the floor or back wall, while commode chairs are usually on wheels. This further increases instability when attempting to transfer to the seat.

[0007] Compared to human-powered wheelchairs, electric wheelchairs are somewhat bulky, and the transfer process may have to take place at a certain distance from the seat of the toilet or commode chair.

[0008] Several devices and assistive tools are available to aid this process and make it safer and easier to manage. These devices are designed to increase user independence and reduce the risk of accidents, although with most of these devices, many individuals still require some assistance from caregivers to transfer successfully. Handrails may be installed near the toilet. Users can grab these handrails to use their upper body strength to lift themselves between the wheelchair and the toilet seat. These require sufficient upper body strength from the user, and they must also be positioned to suit the user's preferred transfer method, which is not always the case. They do not provide any support for the user's lower limbs, so they must raise and lower their weight throughout the transfer.

[0009] These grab bars must also be permanent fixtures for the toilet. Users can install them around their toilet in their homes, but when traveling and needing to use public toilets, the grab bars (if any) may not be suitable. Therefore, they do not offer a portable solution that can be used with any toilet.

[0010] Toilet chairs may have similar armrests or frames to aid in the transfer process. However, with frames typically mounted on wheels, the wheels may shift if the weight transfer causes any tilting. Therefore, the required stability cannot be provided.

[0011] Another solution to this problem is to install a toilet seat lifter. These provide a raised platform that can be attached to an existing toilet seat. They increase the height of the toilet seat, making it easier for users to sit down and get up on the toilet. To get up from the toilet, they need to be able to safely lift their weight to a standing position, which many wheelchair users cannot do. Some models are equipped with armrests or handles to help achieve this and provide additional support. While these devices can provide some support when already installed, they do not offer a portable solution for use with any toilet.

[0012] Fixed rails around the toilet are generally unsuitable for wheelchair users because, by their very nature, they restrict movement. For wheelchair users to move around, the space needs to be as open as possible, so in the best-case scenario, a pull-down handrail on the wall is the only useful assistive device, as they can use it to hold on when moving from the other side or front of the toilet.

[0013] Another solution on the market is a transfer board. The user uses a solid board structure to bridge the gap between the wheelchair seat and the toilet seat or commode seat, then slides their hips across the board to transfer from one surface to another. Existing transfer boards tend to be quite cumbersome to use. Those without any securing device to the toilet or commode do not offer a truly stable option that can be used with confidence.

[0014] A height difference between the toilet seat or commode seat and the wheelchair seat is common. In most cases, the toilet seat or commode seat is much lower than the wheelchair seat, which creates additional risk during descent if the board is free to move. There is a risk that the board may slip off the toilet seat when a lateral downward force is applied. Conversely, as the user begins to rise to return to their wheelchair, the lateral force can dislodge an unsecured transfer board from the toilet seat or commode seat.

[0015] Another option is a patient lift. These are mechanical devices that use slings or harnesses to lift a person from their wheelchair and transfer them to the toilet, and then back. These lifts are typically operated by caregivers and are particularly helpful for individuals with limited upper body strength. They usually take up a considerable amount of space in the bathroom. They must also be permanent fixtures and do not provide a solution for moving the user from one place to another.

[0016] Another option is a toilet safety frame. These are typically self-supporting structures similar to a walking frame, placed around the toilet to provide support when sitting on and getting up from the toilet seat. However, toilet safety frames restrict the space around the toilet, obstructing user movement. They are also often self-supporting and not bolted in place. Therefore, this further presents a stability problem, as they may tilt during use.

[0017] There is a need for a device to support users with mobility issues during transfer to a toilet or commode chair. Stability needs to be provided during the transfer process to ensure user confidence and, where possible, user independence. A solution is needed that can be used in most situations in the home and community, taking into account factors such as: toilet placement and accessibility, the comparison between toilet seat height and wheelchair seat height, wheelchair type, and user preferences.

[0018] The prior art shows many devices that attempt to address these needs in various ways.

[0019] US 2010 175 184 (Cervi) discloses a toilet transfer board system including a base unit that is attached to the rim of a toilet via clamps. The toilet transfer board also incorporates legs that rest on the ground. While it appears to provide a stable solution to the problem, the toilet transfer board seems to always remain in place. This may provide a suitable solution in a user's home environment, where the board can be installed on the best side and in the best position for the user and their preferences, but it does not provide a solution when away from home. The distance from the toilet that a user can place their wheelchair is also limited. The wheelchair end of the transfer board appears difficult to align with the seat of the wheelchair and also difficult to align under the user's hips.

[0020] US Patent 2002 166 166 (Coston) discloses a transfer plate for use on a toilet, wherein one end of the plate has a hook for attaching to the inner rim of the toilet seat or urinal, and a latch for preventing displacement and detachment after placement. This solution appears to provide some stability for the user, but due to the spring-loaded latch arrangement, it can prove difficult for the user to detach it from the toilet seat or rim themselves. In the case of the device latching onto the seat, this requires the seat to be securely attached to the toilet. Toilet seats are typically made of plastic and are therefore weak under lateral forces. They often loosen and experience some lateral movement under load. The transfer plate also interferes when the user sits on the seat.

[0021] US 2006 179 558 (Dupuis) ​​discloses a transfer platform for a toilet seat that can be secured to the seat using a fastener. The platform also provides a notch for the wheelchair wheels to aid stability. This transfer platform again relies on seat fasteners, so if the toilet seat becomes loose, the transfer platform will be subject to any lateral movement. All wheelchairs are different, and the likelihood of the wheel notch perfectly aligning with the wheel is small. In these cases, if it is not aligned, the wheel notch will not be used, and the platform will remain unstable.

[0022] While existing technologies appear to address the issue of providing wheelchair users with a means of moving between their wheelchairs and the seat of a toilet or commode chair, they do not offer a portable solution for use when out and about, or with different toilets and commodes when needed. While they encourage independent living to some extent, they do not provide a safe and stable solution that enables users to use their devices independently without caregiver assistance. They do not appear to offer solutions that accommodate a wide variety of toilets or commode chairs of different shapes and sizes, nor do they appear to offer an easy-to-clean hygienic solution.

[0023] A preferred embodiment of the present invention aims to provide a toilet transfer board that can be used with most toilets. This transfer board allows for quick and easy attachment and removal from the toilet rim, and provides stability for the user moving onto and off the toilet or toilet seat throughout the transfer process. A preferred embodiment of the present invention also aims to provide a portable transfer board that does not need to remain in place on the toilet and is easy to clean for hygienic purposes.

[0052] In the accompanying drawings, the same reference numerals denote the same or corresponding parts.

[0053] It should be understood that the various features shown in the following description and / or figures are preferred, but not essential. The combinations of features described and / or shown are not considered the only possible combinations. Unless otherwise stated, features may be omitted, changed, or combined in different ways where feasible.

[0054] A "toilet" is generally considered a permanent fixture, typically found in a bathroom. A "toilet seat" is typically portable, allowing it to be moved or placed in various locations, and is often used by users with limited mobility. Embodiments of the present invention can be used in conjunction with both a toilet and a toilet seat.

[0055] In the context of this specification, the term "toilet" includes a commode.

[0056] Figure 1a One embodiment of the toilet transfer plate 1 is shown, illustrating a substantially planar body 2 having a first end 3 wider than the second end 4. The first end 3 is configured to be releasably secured to the rim of a toilet or commode chair. The second end 4 is configured to rest on the seat of a wheelchair or lie flat on a bed. As can be seen from the figures, the thickness of the body is small relative to its length and width.

[0057] The first end portion 3 includes a plurality of hook-shaped connectors or supports 11. The figure shows a pair of hook-shaped connectors 11, but the first end portion 3 may include a single hook-shaped connector 11 positioned at the center of the body 2, whereby the single hook-shaped connector 11 can be wide enough for stability. Figure 9 ).

[0058] More than two hook-shaped connectors 11, not shown, may be present at the first end 3. The hook-shaped connectors 11 can pivot about the first end 3 to allow them to be adjusted for different angles and to connect to toilet seat rims 6 of different shapes. Each hook-shaped connector 11 is combined with a hook-shaped element 13 that extends into the toilet bowl 7 or commode bowl, wherein the hook-shaped element is long enough to maintain contact with the inner edge of the rim 6.

[0059] In the case where the first end 3 includes a pair of hook-shaped connectors 11, as shown in the figure, these connectors can converge toward each other. This convergence is to take into account the curvature of the rim and seat of most toilet bowls and commodes.

[0060] The first end 3 can be bent inward to match the curvature of the toilet seat. When the toilet seat is lowered to the position on the rim of the toilet, it is above the hook-shaped connector 11, which helps to fix the toilet transfer plate 1 in place.

[0061] Figure 1b A side view of the toilet transfer plate 1 shows a possible arrangement of at least one hook-shaped connector 11 and an elastic buffer or stop 14, whereby the hook-shaped connector 11 and the buffer 14 form a groove 5 therebetween, the groove 5 being configured to be located on most toilet bowl rims or toilet seats. The groove 5 is a space created between two adjacent surfaces. The hook-shaped connector 11 includes a hook-shaped portion 13 that forms an obtuse angle with the remainder of the connector 11 and forms a first adjacent surface, and the buffer 14 or an alternative elastic member forms another adjacent surface, forming the groove therebetween in which the rim of the toilet or toilet seat will be located.

[0062] In the context of this specification, a slot such as 5 has a substantially radially extending “length” of the toilet bowl that engages with the toilet transfer plate 1 in use, a “width” extending circumferentially along the toilet bowl, and a depth determined by the dimensions of the components defining the slot 5, in this case, the thickness of the hook-shaped element 13 of the connector 11 and the elastic buffer 14.

[0063] The hook-shaped element 13 forms an obtuse angle with the rest of the connector 11.

[0064] The second end 4 is curved outward to present a rounded edge, and the edge may be chamfered to facilitate pushing the second end 4 between the seat of the wheelchair or the surface of the bed and the user. The body 2 of the toilet transfer board 1 includes an inwardly curved first side and a second side to reduce the overall weight of the toilet transfer board 1 and also to help prevent the user from tilting during the transfer. The user inserts the second end 4 under their hips and slides it along the body 2 toward the first end 3. When they are positioned somewhere between the first end 3 and the second end 4, the toilet transfer board may tend to tilt forward in the direction of the user's lower limbs. The curved sides help ensure that the user's weight acts along the central axis of the main body 2, thereby helping to prevent this forward tilting movement.

[0065] Figure 2 One embodiment of the bottom surface of the body 2 of the toilet transfer plate is shown, illustrating a plurality of ribs 15. These ribs 15 provide structural strength to the body 2 while helping to reduce the overall weight of the toilet transfer plate 1. The body 2 with ribs 15 may be molded from plastic. The ribs 15 may include rounded ribs to provide the necessary strength for the toilet transfer plate 1 while also ensuring easy cleaning and eliminating corners where dirt and bacteria may accumulate.

[0066] Preferably, the rib 15 intersects the rest of the body 2 via the curved portion 15a to facilitate cleaning. It is preferable that the rib 15 intersects the rest of the body 2 at a right angle, which makes it more difficult to wipe clean with a cloth.

[0067] Figure 3a An isometric view of the toilet transfer plate 1 is shown, which illustrates the chamfered edges of the body 2, i.e., the entire periphery of the body 2. These edges may be chamfered only at the first end 3 and the second end 4, or they may be chamfered throughout the entire body 2. Figure 4 A bottom view of one arrangement with ribs 15 is shown, which helps to increase the rigidity of the body 2 so as to support the weight of the user without adding too much weight to the body 2 and thus to the toilet transfer plate 1.

[0068] Figure 3b A side view shows a close-up of the hook-shaped connector 11, showing the dimensions of the hook-shaped portion constituting the slot 5, where X is the distance between the hook-shaped element 13 and the buffer 14 or the length of the slot 5, and Y is the depth of the slot 5, corresponding to the length of the hook-shaped element 13 and the thickness of the buffer 4.

[0069] Figure 4A pair of cushioning elements 14 are also shown mounted on the bottom surface of each of the hook-shaped connectors 11. These cushioning elements 14 may include an elastic material to cushion the bottom surface of the body 2, while also helping to prevent lateral movement of the toilet transfer plate 1 when mounted to the rim of the toilet bowl or toilet seat. The cushioning elements 14 may cover the screw holes or fastener holes for securing the hook-shaped connectors 11 to the body 2. These cushioning elements 14 may also be covered with an anti-slip coating or material.

[0070] When using the toilet transfer plate 1, the user can first hook the hook-shaped connector 11 onto the rim 6 of the toilet bowl 7 or around the toilet seat, and then wedge the second end 4 of the body 2 between the wheelchair seat and their hips. They may lower the toilet seat so that it is above the hook-shaped connector 11, wherein the curvature of the first end 3 is very similar to that of most curved toilet seats, so that the first end 3 is positioned next to the toilet seat.

[0071] The user slides themselves along the length of the toilet transfer plate 1 from the second end 4 to the first end 3 and onto the toilet seat. Once finished, they reverse the process, sliding themselves from the first end 3 back to the second end 4 and onto the seat of their wheelchair.

[0072] Alternatively, the user can align their wheelchair with the toilet, inserting the second end 4 under their hips and onto the seat of their wheelchair, while positioning the first end 3 to hang directly above the rim 6 of the toilet bowl 7. In some cases, the wheelchair seat may be higher than the rim 6 of the toilet bowl 7. As the user begins to slide along the length of the body 2 of the toilet transfer plate 1, the first end 3 will descend into place, with the slot 5 resting on the rim 6 of the toilet bowl 7.

[0073] The size of the slot 5 is not large enough to fit all toilet seat rims 6 tightly, but rather long and wide enough to fit most rims 6. Therefore, it is not an interference fit in most cases. However, once the rim 6 is engaged in the slot 5, the longitudinal movement of the plate 2 will be limited by the hook-shaped connector 11 located inside the toilet bowl 7 and the buffer 14 located outside the toilet bowl 7.

[0074] Figure 5 The toilet transfer plate 1 is shown from the second end 4, and Figure 6 The toilet transfer plate 1 is shown from the first end 3. Both figures show that the body 2 of the plate is substantially flat and planar in construction, with rounded edges. In an alternative arrangement, the toilet transfer plate 1 may include straight edges (not shown). The toilet transfer plate 1 may also include a substantially rectangular body 2 (not shown).

[0075] Figure 7The toilet transfer plate 1 in use is shown, wherein the second end 4 rests on the seat of the wheelchair 8, and a pair of hook-shaped connectors 11 are locked onto the rim 6 of the toilet bowl. Figure 8 This same arrangement is shown in a side view. In this embodiment, the body 2 of the toilet transfer plate 1 thins from the first end 3 to the second end 4.

[0076] The hook connector 11 may include an adjustable bracket that allows adjustment of the length of the slot 5 so that the slot 5 can accommodate different thicknesses of the rim 6 of the toilet bowl 7.

[0077] The hook-shaped connector 11 can be removed from the body 2, or alternatively folded beside the body 2 for storage purposes, not shown. Thus, a toilet transfer plate 1 with one or more removable or foldable hook-shaped connectors can be used as a typical transfer plate, wherein the hook-shaped connectors are removed or folded.

[0078] Figure 9 An alternative embodiment with a single hook-shaped connector 11 is shown, which is centrally positioned at the first end 3 of the body 2. This single hook-shaped connector 11 can be wide enough for stability and to prevent tilting, especially when the user moves to and from the seat 9 of the toilet 10.

[0079] The slot 5 in the connector 11 can be straight or curved.

[0080] The groove 5 formed by the hook-shaped end of the hook-shaped connector 11 can be spring-loaded to releasably secure to the rim 6. The hook-shaped connector 11 may include a spring-loaded mechanism (not shown) to grip the rim 6 when in place on the toilet.

[0081] Figure 10a This is a bottom perspective view of an embodiment including a hook-shaped connector 11 with a bimetallic arrangement. The hook-shaped connector 11 incorporates spring steel to help provide cushioning and shock absorption upon contact with the rim 6. The hook-shaped connector 11 includes a main portion 11a made of a relatively rigid material (e.g., 3 mm low-carbon steel) and attached thereto, and a flexible portion 11b made of an elastic material (e.g., 1 mm spring steel) fixed to the body 2. The main portion 11a may be coated with a protective material that provides protection against damage to the toilet bowl when the connector engages with it; and preferably, it also increases the coefficient of friction to inhibit movement of the hook-shaped connector 11 relative to the toilet bowl. Each connector portion 11a, b has two branches 11c that define corresponding grooves 5 therebetween for engaging the rim of the toilet bowl.

[0082] Figure 10b It shows Figure 10aThe hook-shaped connector 11 is shown in one arrangement of a coating or protective layer covering the end portion of the hook-shaped connector 11 and the slot 5.

[0083] The hook-shaped connector 11 can be fixed to the body 2 by bolts, rivets, adhesives and other fastening devices.

[0084] Figure 11 The hook-shaped connector 11 is shown when connected to the body 2 of the toilet transfer plate 1 via the resilient bushing 12. The bushing 12 allows limited movement of the connector 11 and provides a cushioning effect upon impact with the rim 6. A slot 5 is defined between the hook-shaped element 13 and the resilient stop 14.

[0085] The hook-shaped connector 11 can engage with the seat of the toilet 10 instead of the rim 6, wherein the slot 5 is formed to fit on the toilet seat.

[0086] The hook-shaped connector 11 can be angled downward from the body 2 at the first end 3, so that when the rim 6 engages in the slot 5, the hook-shaped connector 11 is raised to be substantially in line with the body 2.

[0087] Although Figure 1 to Figure 8 The shape of the main body 2 can fit most wheelchair users, but Figure 12a The modified body 2 is shown, which is slightly longer and suitable for users of electric wheelchairs and / or wheelchairs with fixed pedals, where a longer transfer distance is required.

[0088] Figure 12b The modified body 2 is shown, larger in width and length, suitable for transferring heavier patients. Figure 12b In the embodiment, body 2 has a generally triangular first portion 12x and an elongated second portion 12y with substantially parallel sides. Body 2 may include straight edges, and the corners may not be rounded, as shown.

[0089] Figure 13 A groove 5, formed in the body 2 and opening downwards, is shown for engaging the rim 6 of the toilet bowl 7. As can be seen in the plan view of this figure, in this embodiment, the groove 5 is curved inwards.

[0090] Figure 14 The toilet seat is shown in its position, having been lowered onto the hook connector 11. The first end 3 of the body 2 is curved to match the curvature of most toilet seats. By lowering the toilet seat onto the hook connector 11, the plate body 2 is substantially flush with the toilet seat in this position, allowing the user to smoothly transfer through and enter the position.

[0091] The first end 3 of the body 2 is curved to accommodate the seat and is also spaced apart from the hook-shaped connector 11 to allow the seat to abut the body 2 when lowered onto the rim 6. This provides additional support for the first end 3 and the hook-shaped connector 11, particularly once the user has moved onto the seat, thus capturing the hook-shaped connector 11 into place on the rim 6. It also provides a more hygienic arrangement for the user, allowing them to move onto the toilet seat instead of the toilet bowl.

[0092] Figure 15 A bed 16 and a commode chair 17 in a typical position next to the bed 16 are shown. A toilet transfer board 1 bridges the gap between the bed 16 and the commode chair 17. The armrests 19, which form part of the frame 18, have been removed from one side of the commode chair 17 to allow access from that side. The body 2 of the toilet transfer board 1 is presented to the patient at a suitable angle to allow them to move from the bed to the commode chair 17 by themselves or with the assistance of a caregiver and return in the opposite direction.

[0093] Another armrest 19 can also be removed from the side of the commode chair 17 to allow access from the other side. Alternatively, the toilet transfer plate 1 can be placed at the front of the commode chair 17 to allow access from the front, not shown.

[0094] Figure 16 A toilet transfer plate 1 with a hook-shaped connector 11 is shown, which hooks onto the toilet seat 20 to ensure that the body 2 of the toilet transfer plate 1 spans the gap between the bed 16 and the toilet seat 17.

[0095] Figure 17 This illustration shows one possible arrangement of a toilet transfer plate 1 configured to span the gap between a wheelchair 8 and a commode chair already parked next to it. Also in this example, the armrests on one side of the commode chair 17 have been removed. The body 2 of the toilet transfer plate 1 is flush with the commode seat 20, and the first end 3 is shaped to fit the contour of the commode seat 20 to ensure no gaps.

[0096] Figure 18 The same arrangement of the toilet transfer plate 1 and the wheelchair 8 is shown, wherein the toilet transfer plate is combined with hook-shaped connectors 11. The hook-shaped elements of these hook connectors 11 hook onto the toilet seat 20 to releasably secure the toilet transfer plate 1 in a suitable position for easy transfer.

[0097] Figure 19An alternative method is shown for releasably securing the toilet transfer plate 1 to the toilet seat 20 of the toilet seat 17. The body 2 of the toilet transfer plate 1 incorporates a plurality of magnets 21. The toilet seat 20 incorporates a plurality of corresponding magnets 21. The toilet transfer plate 1 can be positioned for left-side, right-side, or front-side entry. The magnets 21 within the toilet transfer plate 1 are located at the first end 2 and may be located on the bottom surface, such that they are magnetically attracted to corresponding magnets 21 within or on the surface of the toilet seat 20.

[0098] Figure 20 This arrangement of the toilet transfer plate 1 is shown, which shows that the magnet 21 in the body 2 is releasably fixed to the toilet seat 20 for entry from one side of the toilet seat 17.

[0099] In another arrangement not shown, the fasteners that releasably secure the toilet transfer plate 1 may include hooks and ring fasteners, wherein the hook side is mounted to the toilet transfer plate 1 and the ring side is secured to the toilet 10 or toilet seat 17, or vice versa.

[0100] Figure 21 and Figure 22 An alternative arrangement is shown, in which the toilet transfer plate 1 is interconnected with the toilet seat 20 of the toilet seat 17. In this example, the toilet seat 20 has a cutout 22 that reflects the shape of the first end 3 of the body 2 of the toilet transfer plate 1. By reflecting the shape when the toilet transfer plate 1 is seated within the cutout 22 of the toilet seat 20, the surfaces between the body 2 and the seat 20 are smooth, with no gaps and only small engagements between them. The toilet seat 20 helps prevent any lateral movement of the toilet transfer plate 1 during the transfer process.

[0101] Figure 23 The toilet transfer plate 1 is shown when the hook-shaped connector 11 is provided, wherein the hook-shaped element 13 of the hook-shaped connector 11 is inserted into a groove 24 in the toilet seat 20. These grooves 24 are arranged around the toilet seat 20 to allow various positions of the toilet transfer plate 1 to enter the toilet seat 17.

[0102] Figure 24 A schematic diagram illustrates how a toilet transfer plate 1 with a hook-shaped connector 11 engages with a toilet seat 20. A typical toilet chair 17 includes a toilet seat 20 situated above a toilet bowl 23. The toilet seat 20 can be raised or removed to remove the toilet bowl 23 for emptying. In some toilet chairs 17, the toilet seat 20 and the toilet bowl 23 may comprise a single piece of molded plastic material. The hook-shaped connector 11 is configured to engage with the seat portion in this case.

[0103] The toilet seat 9 or toilet seat 20 can be fixed to or molded as part of the toilet transfer plate 1. The fastener can provide a more permanent arrangement, and the toilet transfer plate 1 can be hingedly mounted to the seat 9 or toilet seat 20, allowing it to rotate into or out of position and enabling transfer from beds or wheelchairs of various heights.

[0104] Figure 25 It shows Figure 24 The bottom view shows that there are multiple reinforcing ribs 15 within the structure of the body 2 of the toilet transfer plate 1 to allow the plate to be appropriately thin and lightweight, yet rigid and able to support the weight of the patient.

[0105] Figure 26 The toilet seat 17 with the toilet transfer plate 1 in place is shown, so that it can be transferred by hooking the toilet bowl 23 at the opening of the toilet seat 23 to the side of the toilet seat 20.

[0106] exist Figure 27 In this design, the toilet transfer plate 1 is connected to the frame 18 of the toilet seat 17 via a tubular element 25, which is rotatably mounted on a horizontal element 26 of the frame 18. Thus, the first end 3 is rotatably mounted to the frame 18, allowing the toilet transfer plate 1 to rotate from an upright or vertical position when not in use, and then lower to a horizontal position when needed. Figure 28 The plate 1 is shown in either a folded or upright position.

[0107] Figure 29 The hook-shaped connectors 11 are shown to be removable and therefore interchangeable or adjustable, and can also be removed for cleaning. In cases where the hook-shaped connectors 11 are interchangeable, they can be configured to be interchangeable and replaceable for specific scenarios. For example, if a particular toilet seat rim 6 has a specific width or shape, the hook-shaped connectors 11 can be changed to hook-shaped connectors 11 with slots 5 or fasteners to accommodate that specific width or shape. Or, in another instance, when a patient needs to be transferred from a bed higher than the seat, the hook-shaped connectors 11 can be changed to those configured to facilitate support of the transfer plate 1 across the height difference.

[0108] The bottom surface of the body 2 of the toilet transfer plate 1 is fitted with a groove, in which the hook-shaped connector 11 can be releasably fixed. In this example, the hook-shaped connector 11 can slide into the groove from the first end 3, but other types are also conceivable, in which the hook-shaped connector 11 is pushed in to engage, or released by a spring-loaded latch (not shown).

[0109] Figure 30 An exploded view shows one embodiment of the hook connector 11, illustrating the component parts constituting the hook connector 11.

[0110] The length of the body 2 from the first end 3 to the second end 4 can be between 40 cm and 60 cm to accommodate different possible distances between the wheelchair and the toilet seat or between the bed and the commode chair. A preferred length for the body 2 used in normal situations is 44 cm. In cases where an additional length of toilet transfer board 1 is required, such as for use with an electric wheelchair, a preferred length is 59 cm. With sufficient structural support and the use of suitable materials, the length can exceed 60 cm.

[0111] The width of the body 2 can be 20 cm to 50 cm at its first end 3 and 8 cm to 30 cm at its second end 4 to accommodate heavier individuals and provide them with greater support during transfer. The preferred width of the second end 4 can be 9 cm to allow the user to insert the end themselves between the seat of the wheelchair or the surface of the bed and the bottom of the user.

[0112] In use, the width of the groove 5 along the edge of the toilet bowl can be in the range of 2 cm to 8 cm, preferably 3 cm.

[0113] During use, the length of the slot 5 in the radial direction of the toilet bowl (e.g.) Figure 3b (As shown by X in the figure) can be in the range of 4 cm to 8 cm, preferably 6 cm.

[0114] Body 2 may include glass-filled nylon plastic or alternative plastic materials, or alternatively, body 2 may include wood. Body 2 may include any material that provides the strength required to support the user's weight while bridging the gap between the wheelchair and the toilet seat rim 6, and is easy to clean for hygienic purposes. Body 2 may include coated or laminated materials.

[0115] The hook-shaped connector 11 may be combined with a coating such as a plastic coating to ensure it is easy to wipe clean and will not damage the toilet seat rim. Alternatively, it may be provided with a non-slip surface for engaging with the rim 6 and preventing any damage to the ceramic rim 6.

[0116] The toilet transfer plate 1 may be combined with a sliding seat (not shown). The sliding seat can slide from the second end 4 of the body 2 to the first end of the body 2, transporting the user from one end of the plate to the other end, and then back again.

[0117] Toilet transfer board 1 can be used with a toilet, but it can also be used with a commode. Similarly, toilet transfer board 1 can be used with both electric and non-electric wheelchairs, but it can also be used when transferring from any other seat or even a bed.

[0118] The toilet transfer board 1 can be carried from one place to another by the user using straps or a carrying bag, which can be suspended from the canvas on the back of their wheelchair, for example, for easy retrieval when needed. Alternatively, it can be placed in the room with the toilet, mounted on a wall, or otherwise installed. The toilet transfer board 1 can also be chained to the toilet. For this purpose, the body 2 can be formed or provided with a "ring" to which the chain or rope can be attached.
