Device for tip-proof transfer, especially physically disabled persons

Description

The invention relates to a device for transferring a person from a first position to at least a second position according to the preamble of claim 1.

It is known to support physically handicapped persons who are dependent on nursing staff when transferring from a first position, e.g. from a wheelchair, to a second position, e.g. onto a toilet, a bed, a motor vehicle or the like (or in the opposite transfer direction) by means of mechanical lifting and/or transfer devices. On the one hand, this makes it possible for such a person to be transferred by just one nursing staff member and

··♦♦··

In addition, the nursing staff themselves are physically relieved as much as possible by such a device.

On the one hand, lifting devices are known that are primarily suitable for severely disabled people who cannot be expected to do much physical activity or no physical activity at all. Such devices require a lot of effort to operate and therefore also time for such a transfer process. These devices are also technically complex and are clearly over-qualified for the primary application area underlying the present invention for disabled people who can certainly stand up and sit down independently to a certain extent.

In addition, devices are known in which the disabled person is moved from the first position, usually the wheelchair position, to the second position, e.g. the toilet position, by means of a rotary lifting device or a turntable, i.e. via a horizontal rotary movement. The second position is usually one of several possible positions, for example in the case of a piece of seating arranged in the immediate vicinity of a bed. These rotating parts serve exclusively to support the turning process. However, supporting and balancing the disabled person during the transfer process must be carried out solely by the caregiver.

A device for supporting standing and other postures of physically handicapped people is known from DE 197 24 770 C 1. The device has a device body mounted on a base plate, on which a relatively small seat is arranged radially on the outside of a seat post, whereby a physically handicapped person sitting on this seat is held fixed to the device body by means of a foot fixation, knee pads and a thorax pad. Handrails are also provided so that the required starting position for the respective therapy can be assumed independently. A coupling for the wheelchair is provided radially on the outside of the seat post. Before use, the wheelchair and the device are mechanically connected by means of the coupling. With the help of the handrails, the disabled person pulls himself onto the seat with his own strength and stands up - according to his physical capabilities - using the foot fixation and the pads for security and support. This known device is used in particular to support the therapy efforts of a disabled person confined to a wheelchair. The entire device body can be rotated using transport rollers attached to the base plate, which means that the device requires a relatively large free space to stand and maneuver. In addition, the device is not very flexible when it comes to adapting to local conditions.

Furthermore, a device for raising people from a sitting to an upright position is known from DE 196 47 498 A 1. The device has a frame and a footrest arranged thereon with a lifting device having a cable pull and a belt. The footrest and the lifting device arranged thereon are arranged so that they can rotate using a rotary drive having a handwheel and a pinion. This device is particularly aimed at ensuring that no third person is required when moving a person and is therefore aimed exclusively at people in need of care who cannot stand up on their own, but can independently operate the lifting mechanism and drive control described therein.

A transfer aid using a turntable is described, for example, in DE 199 04 669 A 1. A stand element that can be pivoted using hinges is arranged on the turntable. The transfer aid has a recess on one side in particular to accommodate the knee area of a helper or a carer. On the opposite side, two recesses, each offset to the outside, are provided to accommodate the knees of the person being transferred. The person being transferred can thus be transferred from a first position to a second position simply by rotating the turntable. However, specially trained personnel are required to operate this transfer aid.

In addition, EP O 633 010 Bl discloses a rotating plate as a seat for physically disabled people. However, this only serves to rotate a disabled person in a sitting position for transfer purposes, but does not enable a wheelchair-bound person to stand upright.

A disadvantage of the above-mentioned devices is that the person being transferred usually feels unsafe during the ascent and descent, not least due to the low tipping safety of these devices, particularly along the ascent or descent direction.

In addition, the known devices either require special training from the caregiver or even require a high level of physical effort that is not beneficial to their health and could, for example, cause back injuries.

In addition, most of the known devices require a relatively large amount of space to achieve the required tipping safety, especially during the aforementioned transfer process, and therefore cannot be brought sufficiently close to the person to be transferred.

It is therefore an object of the present invention to provide a device of the type mentioned at the outset which avoids the aforementioned disadvantages of the prior art.

The device should offer the greatest possible tipping safety, particularly when the person being transferred gets on and off the device, assuming that the person has sufficient physical strength to be able to actively participate in the transfer process. At the same time, the device should be able to be moved as close as possible to furniture or a sanitary facility, e.g. a toilet, and should be able to be moved as easily as possible and with as little effort as possible.

The object is achieved by the features of the main claim. Advantageous developments of the device according to the invention are the subject of the subclaims.

The special feature of the invention is that in a device mentioned at the beginning, at least two support rods are arranged radially outward and essentially vertically with respect to the base part, the lateral distance of which is greater than or equal to a standard person's width, and at least one support part is arranged in the region of the support rods and has at least one support arm directed essentially radially outward.

The support bars arranged radially on the outside, i.e. in an outer area or outside the base part, serve as a support aid for the person to be seated on or off. Since they are arranged at a distance corresponding to a standard person's width,

the person can support themselves on both sides of the support bars and move easily between them. In the area of the support bars, there is also a support part consisting of one or more support elements and at least one support arm. With a single support arm, an 'L' or 'T'-shaped support arm can effectively prevent the device from tipping over sideways in relation to the respective mounting or dismounting position of the person being transferred.

The combination of the handrails and the support part therefore offers a high level of tipping safety when the person being transferred gets on and off, particularly when the person being transferred is standing up or being pulled up from a sitting position, for example in order to get from a seat or a toilet onto the device.

In one embodiment, the support rods are designed as support sticks, which can be made either from a round rod to minimize the risk of injury, or from a profile rod to increase the mechanical load-bearing capacity, or from a combination of the two materials.

The support sticks can also have ball knobs on their free ends, by means of which the person to be transferred can be moved by a simple hand turn

•··· ·♦

can be easily turned around, for example to be able to perform a 180° turn as safely as possible, in order to be able to climb down from the device in the direction of view again after a 180" turn.

In order to be able to transfer people of different heights, it can also be provided that the lateral distance between the handrails is adjustable.

According to a further embodiment, the support part has at least one pivotable pivoting arch support. The pivoting arch support(s) can therefore be folded in towards the base part, in particular for transporting the device, and only folded out for operating the device. This significantly increases the mobility of the device, similar to a sack barrow using the support rods. In order to prevent the pivoting arch support(s) from moving uncontrollably during transport, it can also be provided that it is or are designed to be lockable, in particular magnetically lockable, on the base part.

Due to the swivelling of all the support parts that provide stability and due to the additional transport wheels provided in the area of the support parts, a high level of mobility, i.e. good mobility, of the entire device is achieved. The device is light and requires only a small amount of

Can be moved like a hand truck by one person without much effort.

In a further embodiment, a locking element is additionally arranged on the support part, by means of which the rotating part can be locked in order to further increase the safety or sense of safety of the person being transferred, for example while they are getting on and off.

Because, for the reasons mentioned above, all pivotable parts, in particular the pivoting arch support(s) and the locking element, can only be pivoted using feet, the carer has both hands free while caring for the disabled person, which at the same time increases their sense of security. Both while the disabled person is on the device and while the person is moving from a toilet or a seat to the device, the disabled person has a firm hold that is independent of the carer. There is also no need to maneuver the device while the disabled person is on it or even while it is being turned.

Furthermore, any protruding supports from the device to ensure tipping safety are reduced to an absolute minimum and therefore do not represent a tripping hazard for nursing staff.

Fig. 1 shows a transfer device arranged between a wheelchair 80, indicated by dashed lines, and a toilet bowl 90, also indicated by dashed lines. This has a base plate 1 on which a turntable 2 is mounted so as to be rotatable in the plane of the paper by means of a roller bearing having rollers 44. The turntable is preferably circular in the plane of rotation (which is perpendicular to the plane of the paper), but since the shape of the turntable 2 is of little importance in this case, it can also have any other shape, for example square or polygonal. For reasons of space, however, a round shape is recommended. On the side of the wheelchair 80, a swivel support 3 is connected to the base plate 1. The swivel support 3 has sliding elements 32 on the bottom, which enable the swivel support 3 to slide easily perpendicular to the plane of the paper.

Above the turntable 2 there is also a fixedly connected to the turntable 2 and approximately perpendicular

An upwardly projecting handrail 16 is provided, in the upper area of which a transport lever 50 is arranged, which is pivotably attached in the plane of the paper via a hinge 51. The transport lever serves in particular to enable the transfer device to be easily moved by a (care) person.

To illustrate the functionality of the device shown, it is assumed that a person to be transferred, for example a physically disabled person with minimal arm and leg function, is initially sitting in the wheelchair 80 and is to be transferred from the wheelchair 80 to the toilet bowl 90 using the transfer device. It is also assumed that the swivel support, as shown in Fig. 1, has already been turned by the caregiver in the direction of the wheelchair 80. Furthermore, the turntable 2 with the handrail 16 anchored to it is turned by 180°, i.e. the transport lever 50 points in the direction of the support stick 17.

The person will first approach the device and drive the front wheels 95 of the wheelchair 80 onto the swivel support 3. The person will then try to pull themselves up using the strength of their arms, possibly with the help of the caregiver present, and thereby exert a tipping moment on the entire device in the direction of the wheelchair 80. This tipping moment is compensated by the pressure exerted on the swivel support 3 by the front wheels 95. The possibility of driving the

The placement of the wheelchair on the swivel support 3 therefore provides additional tipping resistance for the entire device, essentially due to the weight of the person being transferred.

After the person to be transferred is standing in the device and holding on to the handrail 16, the caregiver releases the latch 9 with their foot, maintains contact with the person with their free hands and turns them using the turntable 2 until the person is in front of the toilet bowl 90. The caregiver then locks the turntable 2 again. The person to be transferred can now support themselves by changing grips, first with one hand on one of the two ball handles 61 and then with the other hand on the second ball handle, and then sit down on the toilet bowl 90.

The ball heads arranged on the support poles 17 thus serve as a pivot and support bearing for the palm of the hand of the person being transferred. The handrail 16 mounted off-center on the turntable 2 creates a large free standing area 63 and a wide access option between the handrail 16 and the toilet 90.

The front view shown in Fig. 2 in the direction 'B' shown in Fig. 1 clearly shows that the support poles 17 and the handrail 16 are designed to be removable by means of release handles 37 in order to simplify the transport of the transfer device.

Fig. 3 illustrates the structure of the base plate 1. A bridge 20, 21 attached as a reinforcement for the base plate 1 is firmly connected to a support foot 60. Several ribs 6 act as reinforcement for the base plate 1. The ribs 6 can also be designed as an overall bent or welded construction. The ribs 6 can alternatively be fixed to one another and provided with the bridges 20, 21 as a single component. The ribs 6 accommodate support rollers 44 by means of which the turntable 2 is rotatably mounted on the base plate 1.

On the opposite side of a swivel support 3, which is also provided in the embodiment, support elements of a support part 21, 18, 60 (see in particular Fig. 5) are provided, which serve to stabilize the transfer device against tipping in this direction, namely opposite to the arrow 'B' shown in Fig. 1. In addition, running wheels 43 are arranged on the support part 21, 18, 60, by means of which the transfer device can be moved, i.e. displaced, in the manner mentioned.

The turntable 2 has recesses 64 on the outside radially, into which latches arranged in the region of the bridge-shaped support elements 20, 21 engage, whereby the turntable 2 can be fixed in the direction of rotation.

Fig. 4 serves to illustrate the function of the swivel arch support 18. This is designed to be foldable and can be operated via a lever 12 using foot power (of the caregiver) and can be magnetically locked in place via magnets 42 and metal plates 25 during transport or when the transfer device is not in use. The magnets can be clearly seen in Fig. 2 in particular.

In the side sectional view of the elements of the transfer device close to the ground shown in Fig. 5, it can be seen that guide elements 30 are provided between the base plate 1 and the swivel support 3, which on the one hand guide the swivel support 3 concentrically around the base plate 1 and on the other hand absorb the weight forces of the entire device and of a person sitting on it. A rib arrangement 5 additionally anchored on the swivel support 3 serves several functions, namely to mechanically stiffen the swivel support 3, as contact surfaces 55 for lateral adjustment of the swivel support (perpendicular to the plane of the paper) (see also Fig. 5) and as a stop 56 for the front wheelchair wheels 95 (see Fig. 3).

A support rod 17 is attached to the support foot 60, which extends approximately vertically upwards and enables the transfer device to move in a manner similar to the movement of a sack barrow (see also Fig. 8). A bearing 46 is provided between the support foot 60 and the support rod 17, around which a swivel arch support 18 can rotate. The wheel suspension 62

is firmly connected to the support foot 60. The radial guidance of the turntable 2 to the base plate 1 is carried out via the central guide pin 26 which is firmly installed on the turntable 2 and which in turn is guided in a bearing bush 38 which is accommodated in a central bearing housing 13. This central bearing housing 13 is firmly connected to the base plate 1.

Fig. 6 shows a locking mechanism for locking/releasing the turntable 2. The mechanism is accessible from different sides and can only be operated with one foot via a lever 11. The mechanism has in particular two independently operating bolts 9 (see Fig. 7) for locking/releasing the turntable 2. The bolts, only one of which is shown in Fig. 6, are designed as a drop bolt construction and are rotatably mounted on the bridge 20, 21. Figures 3 and 6 show the locked position. Figure 7 shows both bolts in the release position.

Fig. 7 shows the arrangement of the support bearing 8 and the support plate 10. These act as a stop for the turntable 2 when it is raised up as a result of a high tipping moment on the handrail 16. This slows down the turntable when it turns. The carer therefore knows that the disabled person's center of gravity is not yet within the standing area 63 and can intervene accordingly (see also Fig. 6).

Furthermore, it is clear that the handrail 16 rotates with the turntable 2, so that the disabled person is permanently provided with a firm hold even during the rotation.

Finally, Fig. 8 shows the transport of the device by means of the support poles 17 and the wheels 43, according to the principle of a "sack barrow".

Overall, the support sticks have several functions: on the one hand, they serve as a stop for furniture for the disabled, such as a bed. They also serve as a pulling aid and support for the person being transferred when standing up and transferring. At the same time, they serve as a lifting and gripping part when transporting the transfer device.
