Description

Technological background

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

Objects of the invention

For the care of temporarily or permanently bedridden or partially or completely immobile persons or patients in the clinical and non-clinical area, special transfer systems are required that make it possible to bring the persons in need of care into different positions, in other words to position them, to reposition them or to lift them. Suspension lifters or belt systems, for example, are used for this purpose.

A common task for employees in hospitals or care 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 from a bed to an operating table or to an imaging system, for example. Relocating heavily anesthetized patients, in particular, is a major challenge and often places increased physical strain on the nursing staff.

Furthermore, there is a need to bring people who are at least partially unable to move from a seat to a reclining position and vice versa. For example, when patients have to be transferred from bed to wheelchair and vice versa for care.

In addition, it should be possible to bring people to different levels, for example to make it easier to transfer beds. Furthermore, it is desirable that people or patients lying on a lying surface can be repositioned from the supine position to a side position, in which case they can then be washed on the lying surface, for example.

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

Description of the invention

The above-mentioned objects are achieved 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 emerge from the subclaims.

According to one aspect of the invention, a transfer system for clinical or out-of-hospital care is provided for transferring a person from a first position to a second position. The transfer system comprises a lifting device with a lifting column and at least one vertically displaceable cross member. Furthermore, the transfer system comprises at least one elongated transfer element having a base end and a free end, the cross member having at least one coupling element for releasably coupling the base end of the transfer element, which in the coupled configuration is arranged essentially at right angles to the cross member. The at least one transfer element or a plurality of them is preferably arranged horizontally during its intended use, e.g. when repositioning people lying down.

One or more elongated transfer elements can on the one hand be pushed under a seated or lying person as support planks for a transfer so that a person can easily be transported from one room to another, for example. On the other hand, at least one transfer element can be positioned to a person requiring care or assistance in such a way that the person can be moved into a new position by means of the at least one transfer element and optionally with the help of further components such as additional holding elements by means of pulling 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, one or more transfer elements have handles or recesses to hold on to.

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 comprise one or two guide rails for a vertically movable lifting unit or slide. The lifting device can be operated manually, by means of a hydraulic cylinder or by means of a pump. 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 operated by an operator such. B. a carer 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. Cable winch, with the cross member hanging on a cable that is held by a cable winch. A pulley system can optionally be used.
2. b. vertical rack and pinion, whereby the pinion can be driven and moves the cross member on the rack up or down.
3. c. Vertical threaded rod, it 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 slide with the cross member directly or the hydraulic cylinder moves the lifting unit by means of a deflected chain. When using a chain, the cylinder pushes into a U-shaped chain drive, the U with the opening pointing downwards and the arch pointing upwards. On one side, the chain drive is fixed at the bottom or at the level of the lifting device's chassis. In the curve of the U, the pinion pushes up through the cylinder, while the lifting unit is attached to the cross member at the other end of the chain. When the cylinder is lifted, the slide moves upwards 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 coupling and is thus manually and / or with the lifting device and in particular a lifting unit such as a movable slide automated vertically movable. On the other hand, like a conventional high-lift truck, the entire transfer system can be moved at least unidirectionally, preferably via rollers. The transfer system can be maneuvered using a tiller handle or a suitable handle, for example. 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 including a supine or prone position to a second position, in particular the side position, with a holding arm being mountable on the free end of the at least one transfer element, which is located below extends the transfer element plane 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 prone 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 person lying down. The person can then be transferred into the lateral position by means of a targeted movement of the transfer element by means of the lifting device upwards and sideways. That way has the staff have their hands free during the transfer or repositioning and can then easily reach the back for care measures such as washing. The transfer to the side position can be carried out by means of the movement of the transfer element and with an automatic lifting device without the need for force on the part of the caregiver.

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 raised and at the same time essentially perpendicular with respect to the longitudinal axis of the lying surface or was moved parallel to the lying plane, ie in the transverse plane of the person, with the support plate being connected to the holding arm in an articulated and resilient manner, preferably or optionally, and / or preferably having soft material on at least 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 lateral position are comfortable for the person to be supported. Possible counter-movements of the person to be supported in the direction of the support plate can be compensated for by means of the suspension. This ensures a stable side 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 at a distance and essentially parallel to one another under a person to be transferred. In this case, at least three or more transfer elements are preferably made available. 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 in the coupled configuration and to be able to take up 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 people lying down, depending on the size of the person to be transferred, more transfer elements are to be connected to the cross member, a preferred number comprising at least nine, preferably at least ten, transfer elements.

For the transport of 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 size to be expected of a person to be transported. If one or more cantilevers, which are directed parallel to the cross member, are attached to a transfer element that is at 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 lengthen or enlarge the support surface.

The above-mentioned aspect of the invention is based on the underlying principle that sliding transfer elements, which can also be called support plates, bearing prongs, support slats or blades, can each be pushed individually under a person lying down. Since only individual transfer elements or blades with surfaces that reduce friction 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 so that it can lift several times the weight of an average person who usually weighs 80 kg. The lifting column has at least a length of 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 to move the free ends of the cross body separately 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 people lying down 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 lying on the transfer elements. The axis of rotation of the swivel joints is arranged parallel to the transfer elements, that is, horizontally and perpendicularly 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 arrested by a snap-in mechanism as standard. The locking can take place, for example, by manual unlocking by nursing staff applying a minimum force against a spring force. After reaching the desired position, the unlocking is released again and the locking mechanism can safely lock the position. As an alternative to a manually operated locking mechanism, the raising or lowering can also be motorized.

With the help of two or more swivel joints, several support surfaces consisting of a backrest, seat part support, a thigh support and lower leg support can be provided. It is preferred if at least one free end of the Cross member is continuously adjustable. A plurality of transfer elements, preferably at least two or three transfer elements, are preferably 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 to be able to be pushed through narrow passages such as doors. In this way, a person to be transferred can be transported from one hospital room to the other while sitting, both with unidirectional wheels and with omnidirectional wheels on 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 that can be moved vertically on the lifting column; and is pivotable about its longitudinal axis from an uncoupled configuration to the coupled configuration.

Due to the pivotability or inclination of 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 to be coupled of the transfer elements and the cross member is facilitated. For example, by slightly pivoting a hook on the cross member, which is essentially directed obliquely upwards, by inclining the cross member, it is easier to hook into a downwardly directed hook (exemplary coupling element of the transfer element) so that the coupled configuration is reached quickly and safely can be.

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

According to a preferred embodiment, the auxiliary coupling device is arranged between the pivotable area of the cross member and the lifting unit. Furthermore, the auxiliary coupling 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 method step of the coupling can advantageously be simplified. The above-mentioned auxiliary coupling devices can not only be used for easier coupling, but also, with suitable training, for To lock transfer elements in a desired position and / or align. A coupling auxiliary device can therefore also serve as an alignment means, as will be described in the following.

According to a further advantageous embodiment of the transfer system, the lifting device also has lockable alignment means for essentially horizontal alignment of the transfer elements, by means of which the cross member can be aligned by rotating about its longitudinal axis and locked in the holding position of the cross member so that it cannot pivot.

By means of the alignment means, the cross member can be tilted and firmly arrested 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 secure the horizontalization of the transfer elements by the locking. The locking can be done by hand or foot actuation or electrical locking. In the locked position, the cross member can be lifted manually or automatically with the lifting device, whereby all transfer elements with the person to be transferred can be safely lifted on them. The person to be relocated can now be moved by means of the mobile lifting device or the vertically movable lifting unit.

After the person to be transferred has been positioned or lowered to a new position, the cross member is unlocked again by means of the alignment means. The lifting device with the 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 be used for horizontal alignment of the transfer elements or as an auxiliary coupling device. For this purpose, the entire transfer system is inclined by raising or lowering the front or rear rollers.

In a further preferred embodiment, the auxiliary coupling device comprises a pivotable load frame which carries the lifting device and is pivotably 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 that 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 simplify application, since the wedge shape makes it easier to introduce 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 around its longitudinal axis so that the angle of the wedge tip and thus the inclined support surface when it is pushed down can be made horizontal.

In the simplest case, the coupling element can be a ball which is connected to a connecting element or shaft of the transfer element. A large number of other forms of the coupling elements are possible as long as they can be coupled simply and securely to the corresponding coupling element of the cross member. Furthermore, a design 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 alignment in the holding position, the locking mechanism being selected from a group comprising: a fixing screw, an angle lever, brackets on both sides for clasping, Clamping jaws, a toggle lever, at least one clamping device, a receiving groove, socket pins, retaining hooks and combinations thereof.

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

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

• Manual positioning of transfer elements in a substantially parallel direction under the person to be transferred, so that the coupling elements of the transfer elements are substantially aligned in a line;

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 recumbents to a holding position for seated persons 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 having the following method steps:

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

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

It is also possible for the transfer system to be made available as a multifunctional transfer system. For example, the transfer system on the lifting column or on the lifting unit can have a boom. By means of a suspension device attached to the boom, such as a holding eye, loads can be lifted or lifted like a crane be lowered. Furthermore, the entire system can be operated semi-automatically or fully automatically. With the full electrification or motorization, the use of the transfer system becomes even easier and the operator can additionally support the person to be 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. One possible function that can be automatically activated is the method of moving a person lying down 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 on request or independently. For autonomous navigation, the transfer system uses suitable sensors, such as a laser scanner, in order to recognize the spatial conditions and possibly also 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 the nursing staff to operate.

Detailed description of the figures

Fig. 1 shows a side view of an embodiment of a transfer system 100 according to the invention. The transfer system 100 is suitable for clinical or out-of-hospital 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, for example, be transferred to another bed by means of 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 slide or lifting unit 102 which is vertically displaceable 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 aid of a plurality of transfer elements 120 arranged in parallel and coupled in the cross member 112, the person 130 lying down can be lifted with the lifting device 110 (not shown). After the person 130 has been lifted, either the bed 150 with the rollers 166 or the lifting device 110 by means of the Wheels 106, 116 are moved so that, for example, the sheet 190 can be changed or a transfer to another bed or to an operating table can take place.

Fig. 2a shows a schematic top view of the person to be transferred 130 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, a transfer element 120 was pushed under the head 131 and three transfer elements 120 each were pushed under the upper body 132 or the legs 135 of the person lying down. Other distances are conceivable as long as a safe lifting is guaranteed by the number of transfer elements 120. For the lifting, each transfer element 120 has a coupling element 121 for coupling in the cross member 112 (not shown).

Figure 2b shows a side view of an embodiment of a longitudinally stretched transfer element 120. The transfer element 120 has a base end with a coupling element 121 and a free end 125 which tapers flat and can therefore easily be pushed between a base and a person 130 lying or sitting. 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 with low friction for simple pushing in or pulling out. Possible materials are preferably materials that promote sliding, such as Teflon, gorilla glass or polished stainless steel. In addition, the shown variant of the transfer element 120 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 profile can be selected.

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

Figures 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 the coupling, the cross member is 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 reception of the coupling elements 121 in the groove 114 of the cross member 112.

Figures 3c and 3d show the cross member 112 shortly before the complete coupling and after the 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 received. Transfer elements 120 (in Fig. 4 not shown) can be coupled essentially at right angles to the cross member 112 at different distances and parallel to one another, depending on the person. The distance is to be chosen so that they are ergonomically positioned under the person.

Figure 5a FIG. 11 shows a front view of a transfer system, with a plurality of transfer elements 120, by way of example, which are each coupled with their base end in the receptacle or groove 114 of the cross member 112. The transfer elements 120 are arranged with their contact surfaces 123, 123 ', 123 "in such a way that they can safely carry a person 130 lying down. In the area of the head 131, a pillow 126 was arranged on two transfer elements 120 to increase the comfort supported by a total of four transfer elements 120. Furthermore, the thighs 133 and lower legs 134 are each carried by two transfer elements 120.

The transfer elements 120 can advantageously either rotate about the bearing point 122 (as in FIG Figure 5b shown) or the bearing point at the level of the coupling element 121 remains fixed and the bearing surfaces 123 can rotate in relation to the shaft. With the aid 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 area of the body to be supported. For ergonomic positioning of the thighs 133 and lower legs 134, the support surface 123 'was inclined upwards towards the knee and the adjacent support surface 123 "was inclined slightly downwards.

Figure 5b shows an embodiment of a wedge-shaped transfer element 120, a headrest 158 with a strip 208 being mounted on a side surface 169 of the transfer element 120. The headrest can be displaced along the bar 208 and can preferably be locked in the desired position. A pillow or upholstery (not shown here, cf. reference numeral 126 in FIG Figure 5a ) can be inserted into the headrest 158.

Figure 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 bearing surfaces 123 ' and 123 "each rotate the coupling element 121 at the same time. In this way, as in FIG Figure 5a shown an ergonomic alignment to the person to be transferred is possible.

Figure 6a shows a front view of a further 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. The two ends of the cross member 112 are preferably continuously 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 in the direction of the longitudinal axis of the cross member middle part can be reduced in order to be able to drive through doors with the aid of the rollers 106, 116, for example.

When the transfer elements 120 are coupled (in Figure 6a Not shown; see z. B. Figures 20a and b ) the person to be transferred can be raised from a lying position to a sitting position. The swivel joints 118, 119 can be permanently locked or arrested in accordance with the standard by means of a latching mechanism.

Figure 6b FIG. 11 shows a side view of the transfer system of Figure 6a , wherein 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 can 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.

Figure 7a shows another preferred embodiment of the transfer system 100 with a suspension mechanism for the crossbeam 112 on the lifting unit 102. The movable ends of the crossbeam 112 can be continuously adjusted from, for example, a horizontal position to the shown orientations of the movable ends of the crossbeam 112 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 inclined downward by the joint 118 to accommodate lower legs, while the joint 119 is inclined upward to accommodate an upper body to provide a sitting position for the person to be transferred (not shown here) to enable.

In the exemplary embodiment of the transfer system 100 shown, 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 manually and / or automatically shifted vertically along the lifting column 111 via the rollers 207. The suspension mechanism comprises two suspension arms 137 and a connecting element 210 to the lifting unit 102. The connecting element 210 has a pivot bearing 138 in order to pivot 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 inclined or tilted for easier coupling of the coupling elements (see also FIG Fig. 7b-c or Fig. 8 ac for more details).

The transfer elements 120 arranged in the horizontal part of the cross member 112 can be displaced along the longitudinal axis of the central part of the cross member 112, as the double arrow x indicates schematically. Figure 7a shows, by way of example, 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 obliquely upward) can be varied and is not limited to the number shown.

Figure 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 receiving in a corresponding coupling element 121, 199 of the cross member 112 (see Figure 7c ). The transfer system according to Figure 7c , shows a lying surface made of 7 transfer elements and folded out horizontally via the joints 118 and 119. The lying surface was enlarged by means of brackets 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.

Also shows Figure 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 Figure 7a ), which can be moved at least unidirectionally. The rollers 116 are preferably designed as steering rollers and can be moved in all directions. The transfer system can thus advantageously be steered in different directions.

Figure 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 Figs. 8a-Fig. 8c the mode of operation of the hydraulic system or hydraulic cylinder 180 serving as a coupling auxiliary device is shown. Systems other than the hydraulic system shown can also serve as a coupling auxiliary device, such as a threaded spindle, a lever mechanism or an actuator.

Figures 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. Figures 8a and 8b shows the hydraulic cylinder in the uncoupled configuration with the movable part of the hydraulic cylinder 180 retracted.

Figure 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.

Figures 8a-8b show how the cross member 112 in the uncoupled configuration according to the arrow 167 has reached a predetermined angular position in relation 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 ( Figures 8a and 8b ) the hydraulic cylinder is retracted, so that a maximum pivotability or inclination of the cross member 112 up to a predetermined angular position in relation to a horizontal alignment plane (x) for easier access to the coupling element 121 (here coupling element 121 or free end 199 or hook of the T-profile of the crossbeam 112 to a corresponding coupling element 121 (here 191) of a transfer element 120. In relation to the horizontal alignment plane (see double arrow x) the crossbeam is inclined more than 90 ° or it becomes 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.

Figure 8b shows schematically when the transfer element 120 is coupled. In this case, 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.

Figure 8c shows the coupled configuration after the coupling elements 121 are hooked and snapped into one another. The hydraulic cylinder 180 is extended to lock this configuration or the holding position. The previously inclined side wall of the rectangular profile 168 has been moved into an essentially vertical position (see arrow y) by the hydraulic cylinder 180. This coupled configuration is an optimal holding position for a person lying down, since the upper surface of the transfer elements 123 are oriented horizontally.

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 during coupling, but can also facilitate decoupling after a lock has been released, for example.

Figure 9a shows a side view of a wedge-shaped transfer element 120 with coupling element 121 and an 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.

Figure 9b FIG. 13 shows a side view of the wedge-shaped transfer element of FIG Figure 9a and an alignment means is also shown. The support surface 123 is in Figure 9b used for a person 130 lying down, 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 pivot axis for the entire cross member 112, and is preferably located in the central region of the cross member (in Figure 9b not shown) mounted. With the aid 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 has to be applied once to align or level 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 caregiver's foot or by motor or partially automated.

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

Figure 10c shows an alignment lever 197, shown in dashed lines, which indicates the starting position Figure 10b of the inoperative lever illustrated. As also in Figure 10c shown, the alignment means, designed as a foot pedal 197, can be actuated downwards (see the shoe 198 shown schematically with an arrow) to compensate for the inclined position of the support surface 123 of the wedge-shaped transfer element 120 (see upwardly directed arrows at the free end of the transfer element 120 in Figure 10c ). In this way, the support surface 123 of the transfer element 120 can easily be made horizontal.

Figures 11a to 11c show side views of a wedge-shaped transfer element 120 before coupling to the cross member ( Figure 11a ), after coupling ( Figure 11b ) and by alignment ( Figure 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. B. formed a screw. The cross member 112 has a curved front edge 194 for aligning the transfer element 120.

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

In Figure 11b the cross member 112 with the transfer element 120 is brought into contact with the contact surface 193. Optionally, something can still be pushed with the mobile lifting device (illustrated by the essentially horizontal arrows in Figure 11b ) after contact is made.

In Figure 11c the last step for aligning or leveling the transfer element 120 is shown. The contact surface 193 at the base end of the transfer element 120 with the curved leading edge 194 of the crossbeam 112 slides up the crossbeam curvature when the crossbeam 112 is raised by means of 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 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 area 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). The positions shown can optionally be reached using a motor. Optionally, the entire cross member 112 can be rotated even further about its longitudinal axis.

Figures 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 able 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 make the support surface 123 horizontal, the upper clamping jaw 175 presses downwards (see arrow pointing downwards). The transfer element 120 is rotated about a fulcrum 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 Figures 12a and 12b the lower clamping jaw 176 furthermore 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 down further (not shown).

Figures 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 limb 151 and a long limb 152. Said legs 151 and 152 are at right angles to one another and the lever is configured in such a way that it can be pivoted about an axis of rotation 178 at the point of intersection of the legs 151, 152. The transfer element 120 to be coupled has a protruding retaining pin 155 as coupling element 121, which is aligned with the edge of the base end of the transfer element 120.

In Figure 13a the base end of the transfer element 120 is positioned in a receiving bracket 173 of the cross member 112. The retaining pin 155 or the coupling element 121 is then opened by tilting the lever 177, as in FIG Figure 13b indicated by the counterclockwise curved arrow, pressed against the vertical receiving surface 179 of the receiving bracket 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 horizontal (see curved Arrow and upward arrow at the free end 125).

Figures 14a and 14b show side views of a transfer element 120 and a groove 165 arranged in the cross member as a receptacle for 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 corresponds to the outer shape of the coupling element 121.

The coupling element 121 is designed as an essentially pointed nose and has an outer edge 164 and an opposing, partially curved edge 163. The width (not shown) of the nose or the extension in the longitudinal direction of the cross member 121 can correspond approximately to the width of the transfer element. A roller 161 is arranged at the end of the outer edge 164 in order to facilitate the introduction 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, the introduction is facilitated 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 regular fashion Intervals. The smooth-running rollers make it easier to guide the nose into and out of 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 end 125). Simply lifting the cross member 112 by means of the lifting unit (not shown in FIG Figure 14b indicated by the upwardly directed arrow) is sufficient to grasp the downwardly directed 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 to secure the nose against slipping out and to maintain the horizontal end position of the support surface 123 of the transfer element 120 ( Figure 14b ).

Figures 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 T-shaped coupling element 121 of the transfer element 120, which comprises two free legs 128 and 129, can be clasped with the retaining brackets 156, 157 ( Figure 15b ).

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

Figure 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.

Figure 15c illustrates the pressing movement of the punch 153 with the arrow 158, the punch 153 being directed against the lower free leg 129 of the coupling element 121. The punch 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 retaining bracket 157. In this way, the transfer element 120 is aligned such that the bearing surface 123 is arranged essentially horizontally. During the alignment, the free end 125 is moved upwards and thus the support surface 123 is made horizontal (see curved arrow and arrow pointing upwards at the free end 125 of the transfer element 120).

Figures 16a to 16c show details of side views of an alignment means 196 with a safety lever 141 both in front of a safety device ( Figure 16a ) as well as after a backup ( Figure 16b ).

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

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

Also shows Figure 16c a transfer system 100 with said fixable alignment means 196, which can be reliably secured by means of the securing lever 141.

Figures 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 ( Figure 17a ) to the side position ( Figure 17b and Figure 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 the like can be used for fastening. The holding arm 145 is arcuate 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 ( Figure 17a ) and holding the person lying on their side ( Figure 17b ) comfortable for the person to be supported 130.

Figure 17a Figure 12 shows a supine person 130 on a bed 159 with the free end of the support plate 146 partially positioned under the person 130's back 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 over the person 130 and the holding arm 145 is directed from the support surface 123 downwards to the bed 159.

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

After the combined lifting and pulling movement has been carried out along the trajectory 149, the holding arm 145 holds the person 130 stable in the lateral position, as shown in FIG Figure 17b is shown. This position can be used, for example, for washing or treating a patient's wound. Possible counter-movements of the person 130 to be supported 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 side position.

Figure 17c FIG. 13 shows a front view of the transfer system 100 shown in FIG Figure 17b was shown from the side. In this exemplary embodiment, the holding arm 145 with the support plate 146 was mounted on the central transfer element 120 and the support plate extends parallel to the person's back in order to ensure a better hold. In order to enlarge the support surface, instead of or in addition to a longitudinally extending support plate 146, a further holding arm 145 with a support plate 146 can be attached to a further transfer element 120.

Figures 18a and 18b show a transfer system 100 with a chassis 103 of the lifting device 110, with the storage surface 123 being aligned in the horizontal position by lifting (see upward arrow in FIG Figure 18b ) of the chassis 103 takes place 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 take place automatically. The adjustability through the chassis can also be used for easier coupling.

Figure 18c shows an alternative embodiment of the transfer system with a coupling auxiliary device or alignment means. In order to incline 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 compression (see double file 205 for spring movement of the gas spring). In the Figure 18c the inclined configuration is shown for ease of coupling. The ability to tilt over the pivotably mounted load frame 210 enables a hook profile 199 of the cross member 112 to engage more easily in the downwardly directed 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 thus unloaded, so that the coupling process with the transfer elements 120 via the respective coupling elements 121 (see dashed circle in FIG Figure 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 bearing surfaces 123) are easier to achieve. This tilting movement can be supported manually by a handle 209 and / or a foot actuation 204.

The manual and / or automated lifting mechanism of the lifting device 102 for moving a person upwards or downwards (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 weight of the patient can press the load frame 200 downwards (see double arrow 206).

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

Figures 19a and 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 that has an internal reinforcement 139 made of curved sheet metal walls in the center (see FIG Figure 19c ) or welded reinforcement walls ( Figure 19b ) having. In the sectional view Figure 19b the optional weld seams or weld points of the internal reinforcement 139 are marked with the reference symbol 127.

Figures 20a and 20b show front views of a transfer system 100 with cross member 112, which has two swivel joints 118 and 119. The 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 continuously adjustable.

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

Figures 21a-21h shows a further embodiment of the transfer system with a horizontal arm 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 shown in FIG Fig. 21 a, be arranged at the upper end of the vertically displaceable lifting unit 102 and thus form a multi-purpose lifting unit 107. Optionally, the boom can be designed to be pivotable. By means of the suspension device 109, loads can be raised or lowered as with a crane. In this way, a multifunctional transfer system can advantageously be made available.

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

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

Figure 21b shows the person 130 in a sitting position after the lying surface (see lying position in Figure 21a ) by an upward or downward movement of the movable ends of the cross member 112 by means of the swivel joints (not shown) to form a seat made up of a plurality of transfer elements 120. The seat made up 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 on the free end of the transfer elements 120.

In Figure 21c the transfer elements 120 were pushed over the chair seat surface by means of the mobile chassis 103 of the lifting device 110 so that the central 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 that depends on the height of the person sitting. For example, for people who are at least 173 cm tall, 46 cm according to DIN standard 5970 is a 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 in.

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

Figure 21e shows, as the penultimate step, that the transfer elements 120 on which the person is sitting, 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 by the person 130 by means of the rollers 106, 116, as shown in FIG 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 Fig. 21g higher position. This position can be used, for example, to stow the transfer system or for gravity infusion. In the case of gravity infusion, high arrangements of the infusion liquid are advantageous, since the liquid supply is brought about only 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 when one or more infusion bottles, glasses or bags are to be hung. Depending on requirements, other care elements such as a handle can also be attached to the holding eyelet 109 as a stand-up aid. Here too, depending on the needs and size of the person to be supported, for example a handle height can be set via the vertically displaceable lifting device 110. The manipulation for height adjustment is manual and / or automatic. Heights can be set very variably depending on the height of the lifting column 111, whereby the lifting column 111 can extend, for example, between at least about 50 cm (from a standard seat surface height) to a maximum of 200 cm, preferably 190 cm, i.e. less than a standard door frame height.

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

Figures 22a and 22b shows in the front area of the chassis 103 a detector 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 transferring person, provided it is free.

Figure 22a further illustrates how the cross member 112 is moved from horizontal to vertical. The cross member 112 is designed to be at least so long that, after receiving a plurality of transfer elements, it can accommodate an average tall man of 1.80 m in the lying position. The vertical position parallel to the lifting column is also in Figure 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 ( Figure 22b ) is expediently smaller than an average door frame height of approximately 2 m. The vertical position of the cross member 112 can be used, for example, for stowing or for transport.

On the other hand, the width of the transfer system 100 can also be reduced in comparison to the lying configuration of the transfer elements 120 if 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 seat configuration of the transfer elements 120, a person can be pushed through doorways or door sticks 189 with the transfer system (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 extension of the cross member 112 as shown in FIG 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 person 130 lying down and facilitates passage through doors or door frames 189 (see arrow below the chassis 103 in FIG Fig. 24 ).

Figures 25a-25c show views of a further embodiment of a transfer system 100 with a transfer element 120 which can be coupled in the cross member 112 and which has at least one handle 101. In particular shows Figure 25a a transfer element 120 designed as a plate, which, like Figure 25b shows, can be securely locked in the cross member 112. In Figure 25a the transfer element 120 is designed as a one-piece plate with at least one recess in the center 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.

Figure 25b 10 is a side view of the transfer system 100, with a seated person engaging the handles 101 of the transfer element. How Figure 25b shows, the transfer element 120 is designed to raise a person 130 after reaching into the recesses or handles 101 on the coupling side from a sitting position. For this purpose, the transfer element is inclined downwards in the coupled position. Figure 25b shows schematically the movement of the lifting device upwards and to the side (see arrow pointing diagonally upwards), 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.

Figure 25c FIG. 12 shows a top view of the plate or transfer element 120 and the person 130, the support surface 123 being shown from above and that both recesses or handles 101 are held by the person 130. In Figure 25c Does the person 130 to be lifted or erect support themselves not only with their forearms on the support surface 123 (as in Figure 25b ) but also with a large part of the upper body 132. Alternative positions, not shown here, of the person to be raised in relation to the transfer element 120 can result 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 reburied 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 stand-up 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 his back can be brought into the side position easily and without great 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, when it is in the seat configuration, can be used like a wheelchair.
