Description

Technological background

The invention relates to a transfer system and a transfer method for repositioning or rearranging people.

Tasks of the invention

For the care of temporarily or permanently bedridden or partially or completely immobile people or patients in clinical and non-clinical areas, special transfer systems are required that make it possible to move the people in need of care into different positions, in other words to position, relocate or raise them. For example, hanging lifts or belt systems are used for this purpose. From the utility model DE 94 04 944 U1 is a transport lifter for disabled people with a lifting column. Another lifter is from the US patent US 1,857,031 known. Furthermore, concerns the EP 0 599 123 A2 a transfer system held from above with interlocking rows of supporting blades for a physically disabled person. From the US 5,181,289 A A transfer system with two lifting columns and rails in between for hanging elements is known.

A common task for employees in hospitals or nursing facilities is to transfer people or patients. Depending on the person's ability to move, one or more people are necessary to transfer the person, for example, from a bed to an operating table or to an imaging system. In particular, transferring anesthetized patients with a high body weight is a major challenge and often places increased physical strain on the nursing staff. There is also a need to move at least partially immobile people from a sitting position to a lying position and vice versa. For example, when nursing patients have to be transferred from bed to a wheelchair and vice versa.

It should also be possible to move people to different levels, for example to make transferring beds easier. Furthermore, it is desirable that people or patients lying on a lying surface can be repositioned from the supine position to a side position, whereby they can then be washed on the lying surface, for example.

The problems and tasks mentioned should be solved by a system that is as simple and flexible as possible and can be operated by a single carer.

Description of the invention

The above-mentioned tasks are solved by a transfer system and a method for transferring a person according to the features of the independent claims. Preferred and advantageous embodiments of the invention result from the subclaims.

According to one aspect of the invention, a clinical or non-hospital care transfer system is provided for transferring a person from a first position to a second position. The transfer system includes a lifting device with a lifting column and at least one vertically displaceable cross member. Further, the transfer system comprises at least one elongated transfer element having a base end and a free end, wherein the cross member has at least one coupling element for releasably coupling the base end of the transfer element, which is arranged substantially perpendicular to the cross member in the coupled configuration. Preferably, the at least one transfer element or a plurality of them is arranged horizontally during its intended use, such as when repositioning people lying down.

One or more elongated transfer elements can be pushed under a sitting or lying person as support planks for a transfer so that a person can be easily transported from one room to another room, for example. On the other hand, at least one transfer element can be positioned relative to a person to be cared for or in need of help such that the person can be moved into a new position by means of the at least one transfer element and optionally with the aid of further components such as additional holding elements by means of the tensile force and/or pushing force of the mobile lifting device. For example, a person can be moved from the supine position to the side position or from a sitting position to the standing position. In order to raise a person up, one or more transfer elements have handles or recesses for holding.

1. a. Seilwinde, wobei der Querträger an einem Seil hängt, das von einer Seilwinde gehalten wird. Optional kann ein Flaschenzugprinzip eingesetzt werden.
2. b. vertikale Zahnstange und Ritzel, wobei das Ritzel angetrieben werden kann und den Querträger an der Zahnstange auf oder ab bewegt.
3. c. Vertikale Gewindestange, sie sich auf dem Fahrgestell der Hubvorrichtung abstützt und bei Drehung die an der Gewindestange befestigte Hubeinheit oder Schlitten mit dem Querträger auf oder ab bewegt.
4. d. Hydraulikzylinder mit Hydraulikpumpe, wobei der Hydraulikzylinder die Hubeinheit oder Schlitten mit dem Querträger entweder direkt bewegt oder der Hydraulikzylinder die Hubeinheit mittels einer umgelenkten Kette bewegt. Bei der Verwendung einer Kette drückt der Zylinder in einen U-förmigen Kettentrieb hinein, wobei das U mit der Öffnung nach unten weist und der Bogen nach oben weist. Auf einer Seite ist der Kettentrieb unten bzw. auf Höhe des Fahrgestells der Hubvorrichtung fixiert. Im Bogen des U drückt das Ritzel durch den Zylinder nach oben, während am anderen Ende der Kette die Hubeinheit mit dem Querträger befestigt ist. Durch Heben des Zylinders bewegt sich der Schlitten mit dessen doppelter Geschwindigkeit nach oben.

The basic concept of the invention is based on the standard functions of a lifting device or high-lift truck, in which a cross member can be moved up and down on a lifting column in order to easily transfer loads vertically, in particular to raise or lower them. The lifting column can include one or two guide rails for a vertically movable lifting unit or carriage. The lifting device can be operated manually, via a hydraulic cylinder or pump operation. Manual operation is possible using a lifting drawbar with a handle or a pedal. The lifting mechanism can be activated by continuously moving the actuating element up and down. Furthermore, a conventional electric drive for automatic operation is possible, which is carried out by an operator such as. B. a caregiver can be activated via a control panel. For safety reasons, manual operation is preferably also possible with an electric drive, so that the lifting device is semi-electric. One of the following lifting mechanisms can preferably be used:

1. a. Winch, where the cross member hangs on a rope that is held by a winch. A pulley system can optionally be used.
2. b. vertical rack and pinion, where the pinion can be driven and moves the cross member up or down on the rack.
3. c. Vertical threaded rod, which is supported on the chassis of the lifting device and, when rotated, moves the lifting unit or carriage attached to the threaded rod up or down with the cross member.
4. d. Hydraulic cylinder with hydraulic pump, whereby the hydraulic cylinder either moves the lifting unit or carriage with the cross member directly or the hydraulic cylinder moves the lifting unit using a deflected chain. When using a chain, the cylinder pushes into a U-shaped chain drive, with the U with the opening facing down and the arc facing up. On one side, the chain drive is fixed at the bottom or at the height of the lifting device chassis. In the arc of the U, the pinion pushes upwards through the cylinder, while the lifting unit with the cross member is attached to the other end of the chain. By lifting the cylinder, the carriage moves up at twice its speed.

The use of a lifting device in combination with transfer elements according to the invention results in the following advantages, among others: On the one hand, the at least one transfer element is firmly connected to the cross member after being coupled and thus to the lifting device and in particular a lifting unit such as a movable carriage manually and / or automatically movable vertically. On the other hand, the entire transfer system can be moved at least unidirectionally, preferably via rollers, as with a conventional high-lift truck. The transfer system can be maneuvered, for example, using a drawbar handle or a suitable handle. This means that the transfer elements can not only be raised or lowered, but also moved horizontally.

According to an advantageous embodiment, the transfer system is configured to transfer a person from a first position comprising a supine or stomach position into a second position, in particular the side position, wherein a holding arm can be mounted on the free end of the at least one transfer element, which is located below the transfer element level and can be connected at its free end to a support plate for a person in order to transfer a person from the supine or stomach position to the side position.

With the option of mounting a holding arm with a support plate on at least one transfer element or on several transfer elements, the nursing staff can position the support plate at least partially under the back of a lying person. The person can then be transferred into the lateral position by means of a targeted movement of the transfer element upwards and sideways using the lifting device. In this way has The staff has their hands free during the transfer or repositioning and can then easily reach the back for care such as washing. The transfer to the side position can be carried out by moving the transfer element and with an automatic lifting device without the nursing staff having to exert any force.

According to an advantageous embodiment, the free end of the support plate is designed to be positioned under a person lying on their back or stomach in order to support the person in the lateral position after the transfer element has been lifted and at the same time substantially perpendicular to the longitudinal axis of the lying surface or . has been moved parallel to the lying plane, i.e. in the transverse plane of the person, wherein preferably or optionally the support plate is connected to the holding arm in an articulated and resilient manner and/or preferably has soft material at least on one outer surface.

By means of the preferred embodiment with a suspension and/or due to the use of a soft contact material, both the transfer and the holding of the patient in the side position are comfortable for the person being supported. Possible countermovements of the person being supported in the direction of the support plate can be compensated for by means of the suspension. This ensures a stable lateral position.

According to an advantageous embodiment, the transfer system comprises a plurality of transfer elements with at least partially slidable surfaces in order to be positioned spaced apart and substantially parallel to one another under a person to be transferred. At least three or more transfer elements are preferably provided. The cross member has at least three quarters of the length of the lifting column in order to rigidly connect the base ends of the plurality of transfer elements to one another in the coupled configuration and to be able to accommodate the load of the person to be transferred by means of the plurality of transfer elements after the cross member has been lifted. In order to lift a seated person, for example, at least three transfer elements are preferably connected to the cross member. For lying people, depending on the size of the person to be transferred, more transfer elements must be connected to the cross member, with a preferred number comprising at least nine, preferably at least ten transfer elements.

For transporting people lying down, the minimum length of the cross member is preferably 150 cm, in particular 175 cm and particularly preferably at least 190 cm. The preferred length of the cross member essentially corresponds to the average expected size of a person to be transported. If one or more arms that are directed parallel to the cross member are attached to a transfer element standing on the edge of the cross member, the maximum length of the cross member can be reduced become. For example, a headrest can protrude beyond the free end of the cross member and thus extend or enlarge the support surface.

The above-mentioned aspect of the invention is based on the underlying principle that slidable transfer elements, which can also be called support plates, bearing tines, support slats or blades, can each be pushed individually under a lying person. Since only individual transfer elements or blades with friction-reducing surfaces on both sides are positioned, this is usually possible for the nursing staff with little effort. After the transfer elements have been positioned essentially parallel to one another and at regular intervals over the entire length of the person's support surface, the coupling ends of the transfer elements can be firmly and securely coupled to the cross member so that the entire load of the person to be transferred is placed on the majority of the transfer elements can be picked up distributed over the lifting device. The lifting device is designed to lift several times the weight of an average person, who usually weighs 80 kg. The lifting column has a length of at least 50 cm, preferably 100 cm and particularly preferably the lifting column has a minimum length.

According to an advantageous embodiment of the transfer system, the cross member has one or two lockable swivel joints in order to separately move the free ends of the cross body up or down to move an upper body or legs of the person to be transferred and to lock them in a predetermined position. The predetermined positions include at least one horizontal holding position for lying people and one holding position for sitting people.

In this way, the transition from lying to sitting and vice versa is advantageously possible for a person supported on the transfer elements. The axis of rotation of the swivel joints is arranged parallel to the transfer elements, i.e. horizontally and perpendicular to the cross member. The cross member preferably has two swivel joints so that the person can be raised from a lying position to a sitting position. The swivel joints are firmly locked or locked by a snap mechanism as standard. The locking can be done, for example, by manual unlocking by nursing staff while applying a minimum force against a spring force. After reaching the desired position, the unlocking mechanism is released again and the locking mechanism can securely lock the position. As an alternative to a manually operated locking mechanism, the raising or lowering can also be done by motor.

With the help of two or more swivel joints, several support surfaces consisting of a backrest, buttocks support, a thigh support and a lower leg support can be provided. It is preferred if at least one free end of the Cross member is infinitely adjustable. Preferably, a plurality of transfer elements, preferably at least two or three transfer elements, are coupled or connected to the cross member for each support surface.

The sitting position can be used particularly advantageously to reduce the width of the transfer system and thus be able to be pushed through narrower passages such as doors. A person to be transferred can be transported from one hospital room to another in a sitting position using both unidirectional wheels and omnidirectional wheels at the base of the lifting device.

According to a further advantageous embodiment, the cross member is connected by means of a pivot bearing to a lifting unit which is vertically displaceable on the lifting column; and is pivotable about its longitudinal axis from an uncoupled configuration to the coupled configuration.

Due to the ability to pivot or tilt the cross member up to a maximum of 90°, preferably 45° or less, from the starting position (uncoupled configuration), the coupling of the coupling elements of the transfer elements and the cross member to be coupled is facilitated. For example, by slightly pivoting, a hook on the cross member, which is directed essentially obliquely upwards, can be more easily hooked into a downwardly directed hook (exemplary coupling element of the transfer element) by tilting the cross member, so that the coupled configuration is achieved quickly and safely can be.

According to a further advantageous embodiment, the transfer system comprises an auxiliary coupling device which is arranged on the lifting device and is designed, optionally in the uncoupled configuration, to pivot the cross member up to a predetermined angular position based on a horizontal alignment plane (x) for easier access to the coupling element of the cross member to a corresponding coupling element of a transfer element and / or to lock the cross member in the coupled configuration.

The coupling auxiliary device is arranged between the pivotable area of the cross member and the lifting unit. Furthermore, the coupling auxiliary device can be selected from a group comprising:
an actuator, a hydraulic cylinder, a threaded spindle, a preferably lockable lever mechanism and combinations thereof.

In this way, the coupling process step can advantageously be simplified. The above-mentioned coupling aids can not only be used to simplify coupling, but also, with suitable training, to Lock and/or align transfer elements in a desired position. Therefore, an auxiliary coupling device can also serve as an alignment means, as described below.

According to a further advantageous embodiment of the transfer system, the lifting device further has lockable alignment means for essentially horizontal alignment of the transfer elements, by means of which the cross member can be aligned by rotation about its longitudinal axis and can be locked non-pivotably in the holding position of the cross member.

By means of the alignment means, the cross member can be tilted and firmly locked or locked after the transfer elements have been coupled. In this way, the transfer elements can be positioned horizontally and no longer fall out or tip over. The alignment means can ensure the horizontalization of the transfer elements by locking them. The locking can be done by hand or foot operation or electrical locking. In the locked position, the cross member can be raised manually or automatically using the lifting device, whereby all transfer elements with the person to be transferred on them can be safely lifted. The person to be relocated can now be moved using the mobile lifting device or the vertically movable lifting unit.

After positioning or lowering the person to be transferred to a new position, the cross member is unlocked again using the alignment means. The lifting device with cross member is then preferably moved away and the individual transfer elements can be pulled out from under the transferred person in the new lying position.

In addition or as an alternative to alignment means that engage the cross member and tilt it about its longitudinal axis, the chassis of the lifting device can also serve to horizontally align the transfer elements or as an auxiliary coupling device. To do this, the entire transfer system is tilted by raising or lowering the front or rear rollers.

In a further preferred embodiment, the coupling auxiliary device comprises a pivotable load frame which carries the lifting device and is pivotally connected to a chassis of the transfer system in the area of the front axle of the chassis for easier access to the coupling elements; and wherein for pivoting the load frame, spring means and/or a hydraulic system are arranged between the chassis and the load frame or the lifting column.

According to a further advantageous embodiment, the transfer element is wedge-shaped and at the end of the greatest vertical extent of the wedge is a Coupling element arranged for receiving in the corresponding coupling element of the cross member.

A wedge-shaped design can absorb the load moment, which is greatest near the coupling, with sufficient stability. Since the transfer element in this embodiment becomes thinner from the coupling position towards the free end, weight can also advantageously be saved. The wedge shape is not only advantageous for static reasons but also serves to make it easier to use, since the wedge shape makes it easier to insert the transfer elements under the person to be transferred and lifted.

Wedge-shaped transfer elements are preferably used together with alignment means with which the orientation of the cross member can be tilted about its longitudinal axis in such a way that the angle of the wedge tip and thus the sloping support surface when pushed down can be horizontalized.

In the simplest case, the coupling element can be a ball that is connected to a connecting element or shaft of the transfer element. A variety of other forms of coupling elements are possible, as long as they can be easily and safely coupled to the corresponding coupling element of the cross member. Furthermore, an embodiment of the coupling as a quick coupling or interlocking hooks is conceivable.

According to a further advantageous embodiment, the cross member and/or the transfer element has a clamping or locking mechanism for locking and/or aligning in the holding position, the locking mechanism being selected from a group comprising: a fixing screw, an angle lever, angles on both sides for clamping, Clamping jaws, a toggle lever, at least one clamping device, a receiving groove, locking pins, retaining hooks and combinations thereof.

According to a further advantageous embodiment, the lifting device has a storage space on the back, preferably with a base, for receiving the transfer elements and/or is omnidirectionally movable and can be locked with brakes.

According to a further aspect of the invention, there is provided a method for transferring a person from a first position to a second position using a transfer system, comprising the following method steps:

• Manually positioning transfer elements in a substantially parallel direction under the person to be transferred so that the coupling elements of the transfer elements are essentially aligned in a line;
• coupling and locking each of the ends or the coupling elements of the transfer elements to the cross member of the lifting device in a coupled configuration;

In this context, it is further preferred to carry out the following process steps:

• for easier coupling of the coupling elements of the transfer elements, and the cross member, pivoting the cross member in the uncoupled configuration about its longitudinal axis up to a predetermined angular position for easier access of the coupling element of the cross member to the corresponding coupling elements of the transfer elements configuration and / or
• after locking in the coupled configuration, changing the cross member by means of one or two swivel joints from a horizontal holding position for lying people to a holding position for sitting people during or before the load of the person to be transferred has been transferred to a plurality of transfer elements.

According to a further aspect, a method is provided for transferring a person from a first position to a second position using a transfer system, the first position comprising a supine position and the second position comprising a side position, the method comprising the following method steps:

• Assembling a support arm with a support plate on at least one transfer element coupled to the cross member;
• Moving the transfer element above a lying person so that the holding arm with the support plate protrudes beyond the person,
• Positioning the free end of the support plate under the back of the lying person,

The lifting activated via the control signal can preferably take place automatically.

Furthermore, it is possible for the transfer system to be made available as a multifunctional transfer system. For example, the transfer system can have an arm on the lifting column or on the lifting unit. Using a suspension device attached to the boom, such as a holding eyelet, loads can be lifted like with a crane be lowered. Furthermore, the entire system can be operated semi-automatically or fully automatically. With full electrification or motorization, the use of the transfer system becomes even easier and the operator can provide additional support to the person being transferred. A control unit can also be used to navigate and thus steer the entire transfer system or to activate individual process steps or functions. A possible function that can be activated automatically is to move a lying person from the supine position to the side position after attaching a holding arm with a support plate.

In a preferred embodiment, the nursing staff can request the transfer system electronically and the transfer system can navigate to where it is needed upon request or independently. For autonomous navigation, the transfer system uses suitable sensors such as a laser scanner to detect the space conditions and, if necessary, the person to be moved and to control the movements based on the measurement signals. In this way, the transfer system can be positioned accordingly, making it extremely easy for nursing staff to operate.

Detailed description of the characters

Fig. 1 shows a side view of an exemplary embodiment of a transfer system 100 according to the invention. The transfer system 100 is suitable for clinical or non-clinical care for transferring people and can preferably be used in hospitals or care facilities in which people often have to be transferred from a first position to a second position . In the in Fig. 1 In the example shown, a person 130 is shown lying in a bed 150, who can be transferred, for example, using the transfer system 100.

The transfer system 100 has a lifting device 110 with a lifting column 111, a lifting drawbar 105 and at least one vertically displaceable cross member 112. The cross member 112 can be raised or lowered or held at a predetermined height by means of a carriage or lifting unit 102 that can be moved vertically on the lifting column 111. Furthermore, the transfer system 100 has one or more preferably elongated transfer elements 120, which can be accommodated in the storage space 104 when not in use.

A coupling element 121 at the base end of the elongated transfer element 120 can be firmly coupled in the cross member 112. For this purpose, the cross member 112 has at least one coupling element 121 for releasably coupling the base end of the transfer element 120. In the example shown, the transfer element 120 is positioned between the person 130 and the sheet 190. With the help of a plurality of transfer elements 120 arranged in parallel and coupled in the cross member 112, the lying person 130 can be lifted with the lifting device 110 (not shown). After lifting the person 130, either the bed 150 with the rollers 166 or the lifting device 110 can be used Wheels 106, 116 can be moved so that, for example, the sheet 190 can be changed or the bed can be transferred to another bed or to an operating table.

Fig. 2a shows a schematic top view of the person 130 being transferred with a plurality of transfer elements 120. The arrows indicate that the transfer elements 120 with the respective support surface 123 between the person 130 and the support or lying surface 140 are essentially parallel to one another and at regular intervals be pushed for a transfer or rearrangement. In the example shown, one transfer element 120 was pushed under the head 131 and three transfer elements 120 were pushed under the upper body 132 or the legs 135 of the lying person 130. Other distances are conceivable as long as safe lifting is guaranteed by the number of transfer elements 120. For lifting, each transfer member 120 has a coupling member 121 for coupling in the cross member 112 (not shown).

Fig. 2b shows a side view of an embodiment of an elongated transfer element 120. The transfer element 120 has a base end with a coupling element 121 and a free end 125 that tapers flat and can therefore be easily pushed between a base and a lying or sitting person 130. The support surface 123 is connected to the coupling element 121 via a connecting element 122 or a shaft. The support surface 123 and the opposite side are preferably designed to be low-friction so that they can be easily pushed under or pulled out. Possible materials are preferably materials that promote sliding, such as Teflon, Gorilla glass or polished stainless steel. In addition, the variant of the transfer element 120 shown has at least one convex curvature 124 in order to provide an ergonomically shaped support surface for a person 130 and thus a secure and as comfortable hold as possible. The convex curvature shown is optional and other variants of the surface course can be selected.

Furthermore, the support surface 123 or the back of the transfer element can be used for inscriptions and/or drawings (not shown) to operate the transfer system or for advertising purposes.

Fig. 3a to 3d show side views of a transfer element 120, each with a support surface 123 and a coupling element 121 and a cross member 112 that can be coupled therewith. Fig. 3a indicates with the arrow that the cross member 112 can be moved to the coupling or base end of the transfer element 120. The cross member 112 has a receptacle 114 or groove for the coupling element 121. Before coupling, the cross member is arranged tilted about the axis 115 in relation to the horizontal (x). This rotatability of the cross member 112 or tilting about the axis 115 simplifies the inclusion of the coupling elements 121 in the groove 114 of the cross member 112.

3c and 3d show the cross member 112 shortly before complete coupling and after coupling with the cross member 112, the cross member 112 being positioned horizontally in each case. In the coupled position of the Fig. 3d the coupling element 121 is engaged and can preferably be locked. The cross member 112 can hold a plurality of transfer elements 120 at the same time.

Fig. 4 shows a perspective view of the cross member 112 without transfer element 120. The support surface 113 for the shaft 122 of the transfer element 120 and the groove 114 is designed so that a plurality of transfer elements can be accommodated. Transfer elements 120 (in Fig. 4 not shown) can be coupled at different distances and parallel to each other, depending on the person, essentially at right angles to the cross member 112. The distance must be chosen so that they are positioned ergonomically under the person.

Fig. 5a shows a front view of a transfer system, with, by way of example, a plurality of transfer elements 120, each of which is coupled with its base end in the receptacle or groove 114 of the cross member 112. The transfer elements 120 are arranged with their support surfaces 123, 123 ', 123" in such a way that they can safely support a lying person 130. In the area of the head 131, a pillow 126 was arranged on two transfer elements 120 to increase lying comfort. The upper body area 132 is supported with a total of four transfer elements 120. Furthermore, the thighs 133 and lower legs 134 are each supported by two transfer elements 120.

Advantageously, the transfer elements 120 can either rotate about the bearing point 122 (as in Fig. 5b shown) or the bearing point at the level of the coupling element 121 remains fixed and the support surfaces 123 can rotate in relation to the shaft. With the help of this relative rotatability of the transfer parts to one another, the inclination of the support surface 123 in relation to the horizontal can be adapted to the body area to be supported. For ergonomic positioning of the thighs 133 and lower legs 134, the support surface 123' was tilted upwards towards the knee and the adjacent support surface 123" was tilted slightly downwards.

Fig. 5b shows an embodiment of a wedge-shaped transfer element 120, wherein a headrest 158 with a strip 208 is mounted on a side surface 169 of the transfer element 120. The headrest can be moved along the bar 208 and can preferably be locked in the desired position. For greater comfort, a pillow or padding (not shown here, see reference number 126 in Fig. 5a ) can be inserted into the headrest 158.

Fig. 5c shows detailed views of a transfer element 120 in various rotational positions about the longitudinal axis of the transfer element 120, with a rotation of the support surfaces 123 ' or 123", the coupling element 121 also rotates. In this way, as in Fig. 5a shown an ergonomic alignment to the person to be transferred is possible.

Fig. 6a shows a front view of a further exemplary embodiment of a transfer system 100 with lifting column 111 and cross member 112, which has two swivel joints 118 and 119. The arrows 171 and 172 indicate the mobility of the free ends upwards and downwards, respectively. Preferably, the two ends of the cross member 112 are infinitely adjustable. The axis of rotation of the swivel joints is arranged parallel to the transfer elements 120 (in the coupled state; not shown here) and perpendicular to the cross member 112. The cross member 112 has two swivel joints 118 and 119, with which the maximum width can be reduced in the direction of the longitudinal axis of the cross member middle part, for example in order to be able to drive through doors with the help of the rollers 106, 116.

When the transfer elements 120 are coupled (in Fig. 6a Not shown; see e.g. b. Fig. 20a and b ), the person to be transferred can be raised from a lying position to a sitting position. As standard, the swivel joints 118, 119 can be firmly locked or locked using a latching mechanism.

Fig. 6b shows a side view of the transfer system Fig. 6a , whereby the transfer elements 120 have been stowed in a storage space 104 at the level of the rear wheels 106. The storage space 104 is shown in a sectional view and may preferably be a container with a bottom. Alternatively, suspension mechanisms for the transfer elements on a wall of a storage space without a floor are also conceivable.

Fig. 7a shows a further preferred embodiment of the transfer system 100 with a suspension mechanism for the cross member 112 on the lifting unit 102. A stepless adjustability from, for example, a horizontal position into the shown orientations of the movable ends of the cross member 112 can be done by means of the joints 118 and 119, respectively. For this purpose, the joints 118 and 119 each have a locking mechanism. In the exemplary setting shown, the movable end of the cross member 112 is tilted downward by the joint 118 to accommodate lower legs, while the joint 119 has been tilted upward to accommodate an upper body to provide a sitting position for the person to be transferred (not shown here). to enable.

In the illustrated embodiment of the transfer system 100, the middle part of the cross member 112 (between the joints 118 and 119) is attached to the lifting unit 102 via a suspension mechanism. The lifting unit 102 can be moved vertically along the lifting column 111 manually and/or automatically via the rollers 207. The suspension mechanism includes two suspension arms 137 and a connecting element 210 to the lifting unit 102. The connecting element 210 has a pivot bearing 138 for pivoting the cross member 112 via the associated pivotable suspension arm 137 to store. Two pivot bearings 138 with associated suspension arms 137 are provided so that the cross member 112 can be tilted or tilted for easier coupling of the coupling elements (see also Fig.7b-c or Fig. 8ac for more details).

The transfer elements 120 arranged in the horizontal part of the cross member 112 can be moved along the longitudinal axis of the middle part of the cross member 112, as the double arrow x indicates schematically. Fig. 7a shows an example of three transfer elements 120 in the middle part and two transfer elements 120 each, which are arranged on the free ends of the cross member 112. The number of transfer elements 120 and their position relative to the cross member 112 (see double arrow pointing diagonally upwards) can be varied and is not fixed to the number shown.

Fig. 7b shows a transfer element 120 in detail, which is wedge-shaped and at the end of the greatest vertical extent of the wedge a coupling element 191 for inclusion in a corresponding coupling element 121, 199 of the cross member 112 (see Fig. 7c ). The transfer system according to Fig. 7c , shows a lying surface made up of 7 transfer elements that is folded out horizontally via the joints 118 and 119. The lying area was enlarged by means of an arm attached to a side wall 169 of a transfer element 120. In the example shown, a U-shaped headrest 158 is attached to the transfer element 120 with a strip 208.

Furthermore shows Fig. 7c that the transfer system 100 can advantageously be moved by means of a chassis 103 and rollers 106, 116 arranged thereon. The chassis 103 has two wheel arms 211 and 212, each with a front roller 106 (see Fig. 7a ), which can be moved at least unidirectionally. The rollers 116 are preferably designed as swivel rollers and can be moved in all directions. This means that the transfer system can advantageously be directed in different directions.

Fig. 7c shows part of a hydraulic cylinder, which is passed through the central wall of the lifting unit 102 at the level of the cross member. In the following Fig. 8a-Fig. 8c the functionality of the hydraulic system or hydraulic cylinder 180 serving as an auxiliary coupling device is shown. Systems other than the hydraulic system shown can also serve as an auxiliary coupling device, such as a threaded spindle, a lever mechanism or an actuator.

Figs. 8a-8c show different positions or configurations of the coupling auxiliary device, which is designed as a hydraulic cylinder 180. The movable part of the hydraulic cylinder 180 is arranged between the lifting unit 102 and the pivotable end (see arrow 167) of the cross member 112. Fig. 8a and Fig. 8b shows the hydraulic cylinder in the uncoupled configuration, with movable part of the hydraulic cylinder 180 retracted.

Fig. 8a shows in particular the suspension mechanism for the cross member 112 comprising the suspension arm 137, a pivot bearing 138 and the connecting element 210 to the lifting unit 102, which is vertically displaceable with rollers 207. The cross member 112 is designed as a rectangular profile 168 with a T-profile (T) as a coupling element 121, the free end of the T-profile serving as a coupling element 121. The cross member 112 connects the rectangular profile 168 to the elongated T-profile (T) via weld seams.

Figs. 8a-8b show how the cross member 112 in the uncoupled configuration according to the arrow 167 has reached a predetermined angular position with respect to a horizontal alignment plane (x). The inclination is limited here by the stop on the retracted hydraulic cylinder 180. In other words, in the uncoupled configuration ( Fig. 8a and Fig. 8b ) the hydraulic cylinder is retracted, so that a maximum pivotability or inclination of the cross member 112 up to a predetermined angular position based on a horizontal alignment plane (x) for easier access of the coupling element 121 (here coupling element 121 or free end 199 or hook of the T-profile of the cross member 112 to a corresponding coupling element 121 (here 191) of a transfer element 120. With respect to the horizontal alignment plane (see double arrow x), the cross member is inclined more than 90 ° or it becomes the vertical direction y (see upward Arrow y) forms an acute angle with the vertical side wall of the cross member or the rectangular profile 168.

Fig. 8b shows schematically when the transfer element 120 is coupled. The transfer element 120 can at least partially rest on a horizontal plane, not shown. The upper surface 123 is thus inclined with respect to the horizontal (x). Due to the inclination of the cross member 112 in this uncoupled configuration, which is made possible by the retracted hydraulic cylinder 180, the coupling element 121, 199 can more easily engage under the coupling hook 191 of the transfer element 120.

Fig. 8c shows the coupled configuration after the coupling elements 121 are hooked and locked into one another. The hydraulic cylinder 180 is extended to lock this configuration or the holding position. The hydraulic cylinder 180 brought the previously inclined side wall of the rectangular profile 168 into a substantially vertical position (see arrow y). This coupled configuration is an optimal holding position for a lying person because the upper surface of the transfer elements 123 are horizontally aligned.

The pivotability or inclination not only enables easier access of the coupling element 121 of the cross member to a corresponding coupling element 121 of a transfer element 120 when coupling, but can make decoupling easier, for example after releasing a lock.

Fig. 9a shows a side view of a wedge-shaped transfer element 120 with coupling element 121 and an exemplary embodiment of a coupling mechanism. This has a coupling hook 191 and a fixing element 192, which can be designed as a fixing screw or toggle lever.

Fig. 9b shows a side view of the wedge-shaped transfer element Fig. 9a , further showing an alignment means. The support surface 123 is in Fig. 9b used for a lying person 130, with the transfer element 120 being positioned between a bed 159 and the person 130. The alignment means is designed as an alignment lever 196. The alignment lever 196 has a tilting device 195 with a rotation axis for the entire cross member 112, and is preferably in the middle area of the cross member (in Fig. 9b not shown). With the help of the alignment lever 196, the cross member 112 can be aligned exactly horizontally. The arrow at the lower end of the alignment lever 196 indicates the force that must be used once to align or horizontalize the support surface of the person to be lifted until the transfer elements are locked or locked in the desired position. The force can be generated, for example, with a carer's foot or motorized or partially automated.

10a to 10c show side views of a wedge-shaped transfer element 120 with alignment lever 197 before coupling to the cross member ( Fig. 10a ), after coupling ( Fig. 10b ) and by orientation ( Fig. 10c ). The coupling mechanism of the Figures 10a-c is as in Fig. 9 formed with the help of a coupling hook 191 and a fixing element 192. The fixing element is in Fig. 10b rotated to fix the transfer element 120 (see curved arrow).

Fig. 10c shows an alignment lever 197, shown in dashed lines, which indicates the starting position Fig. 10b of the unactuated lever. As further in Fig. 10c shown, the alignment means designed as a foot pedal 197 can compensate for the inclined position of the support surface 123 of the wedge-shaped transfer element 120 by actuating it downwards (see schematically shown shoe 198 with arrow) (see upward arrows at the free end of the transfer element 120 in Fig. 10c ). In this way, the support surface 123 of the transfer element 120 can easily be horizontalized.

Fig. 11a to 11c show side views of a wedge-shaped transfer element 120 before coupling to the cross member ( Fig. 11a ), after coupling ( Fig. 11b ) and by orientation ( Fig. 11c ). The coupling mechanism of the Figures 11a-c is with the help of a coupling hook 191 and an optional fixing element 192 such as. B. formed a screw. The cross member 112 has a curved front edge 194 for aligning the transfer element 120.

In Fig. 11a the arrow directed towards the transfer element 120 illustrates that the cross member 112 is moved with the mobile lifting device (not shown) to the transfer element 120 or to a plurality of transfer elements 120, the surfaces 193 of which are aligned at the base end with the contact surface 193 shown of the transfer element 120 can.

In Fig. 11b the cross member 112 is brought into contact with the transfer element 120 with the contact surface 193. Optionally, a little more can be pushed using the mobile lifting device (illustrated by the essentially horizontal arrows in Fig. 11b ) after contact has been made.

In Fig. 11c the final step for aligning or horizontalizing the transfer element 120 is shown. The contact surface 193 at the base end of the transfer member 120 with the curved front edge 194 of the cross member 112 slides up the cross bar curvature when the cross member 112 is raised by the lifting device (not shown). When the end position is reached, the free end 125 of the transfer element 120 rises (see curved and vertical arrow at the free end or the original position of the transfer element 120 in gray shading) so that the support surface 123 reaches a horizontal arrangement. The arrow 186 points to a contact surface or contact point between the transfer element 120 and the front edge 194 of the cross member 112. Rollers can advantageously be arranged on the contact surface of the transfer element 120 or on the contact surface 194 of the cross member 112 in order to minimize the friction until the end position is reached.

The end position reached can optionally be secured with the fixing element 192 (indicated by arrow 182). Reaching the positions shown can, if necessary, be done by motor. Optionally, the entire cross member 112 can be rotated even further about its longitudinal axis.

12a and 12b show side views of a cross member 112 with clamping jaws 175, 176, which are designed to securely hold and align the transfer element 120 during a clamping process. In order to be optimally clamped between the upper clamping jaw 175 and the lower clamping jaw 176, the base end of the transfer element 120 or the coupling element 121 is designed as a flat clamping nose 183. Furthermore, the wedge-shaped transfer element 120 has a right angle at the connecting line between the shaft 122 and the wedge-shaped body of the transfer element 120, which can engage in the receiving angle 173 of the lower clamping jaw 176.

To horizontalize the support surface 123, the upper clamping jaw 175 presses downwards (see downward arrow). The transfer element 120 is rotated about a pivot point near the base end of the transfer element 120 and thereby moves its free end 125 upwards (see curved arrow and upward arrow on free end 125). In the 12a and 12b the lower clamping jaw 176 also has an inclined surface which rises towards the free end 125, so that a slightly sloping inclination of the support surface 123 towards the cross member can be generated when the clamping jaw 175 is pressed further downwards (not shown).

13a and 13b show side views of a transfer element 120 that can be aligned with a lever mechanism. The lever 177 is arranged above the cross member 112 and has a short leg 151 and a long leg 152. The legs 151 and 152 mentioned are at a right angle to one another and the lever is configured so that it can be pivoted about an axis of rotation 178 at the intersection of the legs 151, 152. The transfer element 120 to be coupled has a projecting retaining pin 155 as a coupling element 121 for coupling, which is aligned with the edge of the base end of the transfer element 120.

In Fig. 13a the base end of the transfer element 120 is positioned in a receiving angle 173 of the cross member 112. Subsequently, the retaining pin 155 or the coupling element 121 is tilted by tilting the lever 177, as in Fig. 13b indicated by the counterclockwise curved arrow, pressed against the vertical receiving surface 179 of the receiving angle 173 (see horizontal arrow in the direction of the short leg 151 of the lever. In this way, the free end 125 is moved upwards and thus the support surface 123 is horizontalized (see curved Arrow and upward arrow at free end 125).

14a and 14b show side views of a transfer element 120 and a groove 165 arranged in the cross member to accommodate the coupling element 121 and as an alignment means. The groove 165 is essentially wedge-shaped or V-shaped. Alternatively, U-shaped grooves or other shapes can also be provided, as long as the receiving shape essentially matches the outer shape of the coupling element 121.

The coupling element 121 is designed as a substantially tapered nose and has an outer edge 164 and an opposite, partially curved edge 163. The width (not shown) of the nose or the extension in the longitudinal direction of the cross member 121 can approximately correspond to the width of the transfer element. A roller 161 is arranged at the end of the outer edge 164 to facilitate the insertion of the nose or the coupling element 121 into the groove 165. Depending on the width of the nose in the longitudinal direction of the cross member, several rollers 161 can be provided. Furthermore, insertion is made easier by a roller 162 or several rollers 162 on the cross member 121 at the edge of the groove 165. Alternatively, the rollers 161 and 162 can also be arranged on both sides of the coupling element 121 or on the opposite walls of the groove 165 in a regular manner distances. The smooth-running rollers make it easier to guide the nose into or out of the groove 165.

The advantage of using the groove 165 is that no further lever is required to fix or align the transfer element 120 (see upward arrows at the end 125). Simply lifting the cross member 112 using the lifting unit (not shown) (in Fig. 14b indicated by the upward-pointing arrow) it is sufficient to grasp the downward-pointing nose or the coupling element 121 and to align the support surface 123 of the transfer element 120 horizontally. In addition, fixing elements (not shown) can be inserted through at least one side wall of the groove 165 in order to secure the nose against slipping out and to maintain the horizontal end position of the support surface 123 of the transfer element 120 ( Fig. 14b ).

Fig. 15a to 15c show side views of a wedge-shaped transfer element 120 and a cross member 112 with two retaining brackets 156, 157, preferably in the form of angles. Furthermore, the coupling mechanism has a stamp 153 which serves as an alignment means. The holding brackets 156, 157 can be used to clasp the T-shaped coupling element 121 of the transfer element 120, which includes two free legs 128 and 129 ( Fig. 15b ).

First, as in Fig. 15a shown, with the holding brackets 156, 157 open, the lower holding bracket 157 is moved to the base end of the transfer element 120 so that the lower holding bracket 157 engages behind the lower free leg 129 of the coupling element 121 (see Fig. 15a ).

Fig. 15b shows a downward movement 154 with which the upper retaining bracket 156 engages behind the upper free leg 128 of the coupling element and thus clasps the base end of the transfer element 120 and secures the transfer element 120 against falling out of the cross member 112.

Fig. 15c illustrates the pressing movement of the stamp 153 with the arrow 158, the stamp 153 being directed against the lower free leg 129 of the coupling element 121. The stamp 153 serves as an alignment means in that the lower free end 129 of the coupling element 121 presses against the vertical of the lower holding bracket 157. In this way, the transfer element 120 is aligned so that the bearing surface 123 is arranged essentially horizontally. During alignment, the free end 125 is moved upwards and thus the support surface 123 is horizontalized (see curved arrow and upward arrow at the free end 125 of the transfer element 120).

Fig. 16a to 16c show details of side views of an alignment means 196 with a safety lever 141 both in front of a safety ( Fig. 16a ) and after a backup ( Fig. 16b ).

Fig. 16a and b show how the end position of the alignment means 196 can be secured by moving the locking lever 141 and thus a locking pin 144. For manual operation, the safety lever 141 has a spherical handle. Advantageously, the safety lever 141 can be manual operation and safety in one. Fig. 16a shows the safety lever 141 in the non-locking or securing position 141 essentially at right angles to the longitudinal axis of the alignment means 196.

Fig. 16b shows schematically how the safety lever 141 was moved from the non-locking position (see safety lever 141 in dotted lines) into the locking position about the axis of rotation 143 by means of a downward movement (see arrow 142). During this movement, the alignment means 196 is simultaneously pivoted downwards (see arrow at the lower end of the alignment means 196). The locking pin 144 engages the alignment means 196 to secure it.

Furthermore shows Fig. 16c a transfer system 100 with said definable alignment means 196, which can be reliably secured by means of the safety lever 141.

Fig. 17a to 17c Transfer system with a transfer element and mounted holding arm 145 for transferring a person 130 lying on a bed from the supine position ( Fig. 17a ) to the side position ( Fig. 17b and Fig. 17c ).

The holding arm 145 can be mounted on the free end 125 of the at least one transfer element 120 by means of a fastening or fixing element 148. For example, a clamp, screw or something similar can be used for fastening. The holding arm 145 is curved and is connected to the support plate 146 via a joint 147. According to an advantageous embodiment, the support plate 146 is connected to the holding arm 145 via a resilient joint 147 and has soft material on at least one outer surface. By means of the suspension and the use of a soft contact material, it is possible to slide it under the back ( Fig. 17a ) and keeping the person lying on their side ( Fig. 17b ) comfortable for the person being supported 130.

Fig. 17a shows a person 130 lying in the supine position on a bed 159, with the free end of the support plate 146 partially positioned under the back of the person 130 by a caregiver. The transfer element 120 is positioned above the person 130 on the lifting column 111, so that the end 125 of the transfer element 120 protrudes beyond the person 130 and the holding arm 145 is directed downward from the support surface 123 to the bed 159.

The dashed arrow 149 shows schematically a movement trajectory that completes approximately a quarter circle. This trajectory 149 can be carried out by a combination of lifting (see upward arrow) of the transfer element 120 by means of the lifting device 110 and simultaneous horizontal translation of the entire system or transfer system 100 (see sideways arrow above the chassis) by means of the rollers 106, 116 from the bed 159. This trajectory 149 can be used to raise the patient 130 into the side position. Activation can be done by command via a joystick, voice commands, buttons or remote control. After activating the transfer system 100, a caregiver can monitor the repositioning and, if necessary, move the legs of the patient 130 into a position adapted to the lateral position.

After carrying out the combined lifting and pulling movement along the trajectory 149, the holding arm 145 holds the person 130 stably in the side position, as shown in Fig. 17b is shown. This position can be used, for example, to wash or treat a patient's wound. Possible countermovements of the person to be supported 130 in the direction of the support plate 146 can be compensated for by means of the suspension in the joint 147. This ensures a stable lateral position.

Fig. 17c shows a front view of the transfer system 100, which is in Fig. 17b was shown from the side. In this embodiment, the support arm 145 with support plate 146 was mounted on the middle transfer element 120 and the support plate extends parallel to the person's back to ensure better support. In order to increase the support surface, a further holding arm 145 with a support plate 146 can be attached to a further transfer element 120 instead of or in addition to a longitudinally extending support plate 146.

18a and 18b show a transfer system 100 with a chassis 103 of the lifting device 110, with the bearing surface 123 being aligned into the horizontal position by lifting (see upward arrow in Fig. 18b ) of the chassis 103 at the level of the front rollers 116. In the example shown, the lifting takes place by setting up the connecting joint 117 of the front rollers 116 with the chassis 103. This can preferably be done automatically. The alignability through the chassis can also be used for easier coupling.

Fig. 18c shows an alternative embodiment of the transfer system with an auxiliary coupling device or alignment means. In order to tilt the lifting device 110, a pivotable load frame 200 is provided, which carries the lifting device 110 and thus the lifting column 111 and the cross member 112 attached to it. In particular, a structure of the chassis 103, which is designed here as a load frame 200, is in the area of the front axle of the chassis 103 for easier access to the coupling elements 121 pivotally connected to the chassis 103. To support the inclination of the structure or pivoting of the free end of the load frame 210, a hydraulic system (gas spring 202) is arranged between the chassis 103 and the lifting column 111.

The gas spring 202 can be activated with a gas spring actuation 203 or released again after deflection (see double file 205 for spring movement of the gas spring). In the Fig. 18c The tilted configuration is shown for easier coupling. The ability to tilt via the pivotally mounted load frame 210 enables a hook profile 199 of the cross member 112 to snap more easily into the downward-facing coupling hooks 191 of the transfer elements 120. In this way, the load frame 200 can be tilted towards the patient without transfer elements 120 (not shown) and therefore unloaded, so that the coupling process with the transfer elements 120 can be carried out via the respective coupling elements 121 (see dashed circle in Fig. 18c ) and the subsequent possible locking process as well as a subsequent alignment, not shown here, of a person lying on the transfer elements 120 (horizontalization of the support surfaces 123) are possible more easily. This tilting movement can be supported manually by a handle 209 and/or a foot control 204.

The manual and/or automated lifting mechanism of the lifting device 102 for moving a person up or down (see also upper arrow 206) is also fully operational in an inclined position. If a person lies on the transfer elements 120 and the lying surface is raised by the lifting device 102, the patient's weight can push the load frame 200 downwards (see double arrow 206).

After coupling, the gas spring 201 is deflected downwards (not shown), so that the load frame 200 rests on the chassis 103 or substructure, and the wing 123 of the transfer element 120 is aligned essentially horizontally. This can be supported by a foot actuation 204 if the patient's weight is not sufficient to achieve the desired downward deflection. The spring can preferably be locked in the compressed position in order to be able to transport a lying person safely and in a horizontal position.

Fig. 19a and Fig. 19c shows perspective views of an embodiment of a transfer element 120. The cross section of the transfer elements 120 is each trapezoidal. The transfer element 120 can be designed as a hollow profile, which centrally has an internal reinforcement 139 made of bent sheet metal walls (see Fig. 19c ) or welded reinforcing walls ( Fig. 19b ) having. In the section view Fig. 19b the optional weld seams or weld points of the internal reinforcement 139 are marked with the reference number 127.

Figs. 20a and 20b show front views of a transfer system 100 with a cross member 112, which has two swivel joints 118 and 119. Arrows 171 and 172 show the mobility of the free ends of the cross member 112 upwards or downwards. The two ends of the cross member 112 are preferably infinitely adjustable.

While the Fig. 20a shows the lying position Fig. 20b a possible sitting position where the support surface for the lower legs 134 has been moved downwards and the support surface of the upper body 132 has been moved up. In the sitting position, the transfer system 100 can easily be driven through doors or narrow passages with a person 130 sitting on it (see also Fig. 23 ).

Fig. 21a - Fig. 21h shows a further exemplary embodiment of the transfer system with a horizontal boom 108 for a suspension device 109, which in this example is designed as a holding eyelet. The boom 108 is arranged horizontally on the lifting column 111 of the lifting device 110 and can be attached to the upper end of the lifting column 111 (not shown). Alternatively, the boom 108 can be as in Fig. 21 a shown at the upper end of the vertically movable lifting unit 102 and thus form a multi-purpose lifting unit 107. Optionally, the boom can be designed to be pivotable. Using the suspension device 109, loads can be raised or lowered like with a crane. A multifunctional transfer system can thus advantageously be provided.

Fig. 21b to 21g show side views of the transfer system, with a person sitting on the transfer elements 120 being repositioned on a chair.

Fig. 21a shows the cross member 112 in the horizontal position, so that the person to be transferred 130 lies on a plurality of the transfer elements 120. The cross member 112 is positioned by means of the lifting device 110 so that the transfer elements 120 are arranged slightly above the seat of the chair 170.

Fig. 21b shows the person 130 in a sitting position after the lying surface (see lying position in Fig. 21a ) was converted into a seat made up of several transfer elements 120 by an upward or downward movement of the movable ends of the cross member 112 by means of the swivel joints (not shown). The seat made of transfer elements 120 has an upright backrest, the inclination of which is selected so that the angled cross member 112 can be pushed over the chair 170. An armrest (not shown) can preferably be mounted at the free end of the transfer elements 120.

In Fig. 21c the transfer elements 120 were pushed over the chair seat surface by means of the mobile chassis 103 of the lifting device 110 in such a way that the middle transfer elements 120 positioned in a horizontal line can be lowered by means of the lifting unit 102 so that they rest on the chair surface. The seat height corresponds to a standard height which depends on the height of the person sitting. For example, for people with a height of at least 173 cm, 46 cm is one according to DIN standard 5970 usual standard seat height. If the transfer system 100 has an armrest (not shown) at the end of a transfer element 120, this can be dismantled or folded up.

As soon as the main load of the seated person 130 has been absorbed by the chair 170, the nursing staff can release the locking of the transfer elements 120. As in Fig. 21d shown schematically, the transfer elements 120 of the backrest and the lower leg area can first be released from the cross member 112. The user can now roll the transfer system 100 away from the bed as desired and then pull out the transfer elements 120 and place them in the storage space 104 for storage.

Fig. 21e shows as the penultimate step that the transfer elements 120 on which the person sits, in other words the seat slats, are removed. In Fig. 21f All transfer elements 120 are arranged in the storage space and the transfer system can be moved away from the person 130 by means of the rollers 106, 116, as shown in Fig. 21g is shown.

Fig. 21h shows the transfer system, with the vertically displaceable lifting unit 102 and thus the extension arm 108 in a comparison to Fig. 21g positioned in a higher position. This position can be used, for example, to stow the transfer system or for gravity infusion. In gravity infusion, high arrangements of the infusion fluid are advantageous because the fluid supply is only effected by the hydrostatic pressure gradient between the infusion bottle and the patient. The height of the extension arm 108, as in Fig. 21h shown, can therefore be used advantageously if one or more infusion bottles, glasses or bags are to be hung up. Depending on requirements, other elements used for care, such as a handle as a standing aid, can also be attached to the holding eyelet 109. Here too, depending on the needs and size of the person to be supported, for example a handle height can be adjusted via the vertically displaceable lifting device 110. The manipulation for height adjustment is manual and/or automatic. Heights can be adjusted very variably depending on the height of the lifting column 111, with the lifting column 111 being able to extend, for example, between at least approximately 50 cm (from a standard seat height) to a maximum of 200 cm, preferably 190 cm, ie smaller than a standard door frame height.

Fig. 22a shows a front view of a transfer system 100 with travel drive and control unit 187. Fig. 22b is a side view of the in Fig. 22a shown transfer system 100. With the help of the control unit 187, the entire transfer system 100 or parts of it (such as the lifting device) can be navigated, steered or moved. For this purpose, a steering and travel drive and an energy supply, such as. B. a battery, provided. A drive can drive the wheels 106, 116. The wheels can be actively steering or pushed manually. The motor-controlled functions are activated with a hand-held control device. The control signals can be sent to the transfer system 100 using Local radio or cable can be transmitted. With full electrification and automation, the use of the Transfer System 100 becomes even easier.

Fig. 22a and Fig. 22b shows a detector in the front area of the chassis 103 which is designed as a laser scanner 188. With the help of such a detector, obstacles or boundaries such as walls can be detected and driving can be automated. On request, the transfer system 100 can come to the person transferring, provided it is free.

Fig. 22a further illustrates how the cross member 112 is moved from the horizontal to the vertical. The cross member 112 is designed to be at least long enough to accommodate a man of average height of 1.80 m in the lying position after receiving a plurality of transfer elements. The vertical position parallel to the lifting column is also in Fig. 22b shown. In this position of the cross member 112, the width of the transfer system 100 is reduced transversely to the lifting column 111 and only the width of the chassis 103 determines the space required by the lifting device 110. The total height of the transfer system 100 with vertical cross member 112 ( Fig. 22b ) is expediently smaller than an average door frame height of approx. 2 m. The vertical position of the cross member 112 can be used, for example, for storage or transport.

On the other hand, the width of the transfer system 100 can also be reduced compared to the lying configuration of the transfer elements 120 when the sitting position of the cross member 112 is adjusted. The transfer elements 120 remain anchored in the cross member 112 and can carry a person 130. This seating configuration is in Fig. 23 shown. Due to the seating configuration of the transfer elements 120, a person can be pushed with the transfer system through doorways or doorways 189 (see horizontal arrow in Fig. 23 ).

Fig. 24 shows the case that the rollers 106, 116 can be moved omnidirectionally, so that the transfer system 100 can be pushed laterally, ie in the direction of the longitudinal extent of the cross member 112 as shown in Fig. 24 is indicated (see arrow 160 in Fig. 24 ). This is advantageous if the cross member 112 is positioned in a horizontal position for transferring a lying person 130 and makes it easier to pass through doors or door frames 189 (see arrow below the chassis 103 in Fig. 24 ).

Fig. 25a-Fig. 25c show views of a further embodiment of a transfer system 100 with a transfer element 120 that can be coupled to the cross member 112 and has at least one handle 101. In particular shows Fig. 25a a transfer element 120 designed as a plate, which, like Fig. 25b shows, can be securely snapped into the cross member 112. In Fig. 25a the transfer element 120 is designed as a one-piece plate with at least one recess in the middle of the support surface 123 for receiving an upper body of a person 130. The Transfer element 120 can alternatively be formed from two individual elongated transfer elements 120, each with a handle.

Fig. 25b is a side view of the transfer system 100, with a seated person engaging in the handles 101 of the transfer element. How Fig. 25b shows, the transfer element 120 is designed to raise a person 130 from sitting after engaging the recesses or handles 101 on the coupling side. For this purpose, the transfer element is inclined downwards in the coupled position. Fig. 25b shows schematically the movement of the lifting device upwards and laterally (see diagonally upward arrow), so that the person 130 is pulled or lifted from the sitting position by the chair 170 into the standing position by means of the moving cross member 112.

Fig. 25c shows a top view of the plate or transfer element 120 and the person 130, with the support surface 123 being shown from above and that both recesses or handles 101 are held by the person 130. In Fig. 25c The person 130 to be lifted or stood up does not only rely on the forearms on the support surface 123 (as in Fig. 25b ) but also with a large part of the upper body 132. Alternative positions, not shown here, of the person to be raised up in relation to the transfer element 120 can arise depending on the person's ability to move.

In summary, the transfer system is a multi-purpose transfer system and can be used for many different functions in the care sector. On the one hand, patients or other people in need of care can be rebed in a relaxed and safe manner. On the other hand, one or two transfer elements can also be equipped with handles to serve as a standing aid when lifting and moving the lifting device. If a holding arm with a support plate is mounted on the free end of the transfer element, a person lying on their back can be brought into the side position easily and without much effort on the part of the nursing staff. Furthermore, an armrest can also be positioned on one or two transfer elements so that the transfer system can be used like a wheelchair when it is in the seating configuration.

    lifting the person into a transporting position with the hoisting device (110);

    optionally moving the transfer system by means of the hoisting device (110);

    lowering the person by means of the hoisting device (110); and

    releasing the lock and pulling out the transfer elements (120).
13. The method according to claim 12, further comprising the following method steps:
    after locking in the coupled configuration, shifting the crossbeam (112), by means of one or two hinged joints (118, 119), from a horizontal holding position for lying persons into a holding position for seated persons during or before the load of the person to be transferred has been transmitted to a plurality of transfer elements (120).
