Figures 3 to 5 show schematically the operation of a mobi ^¬ len changing device.

Figure 1 shows a mounted on a patient bed OF INVENTION ^¬-making device according to. The patient bed has a frame 1 with a device attached thereto for receiving a mattress 2. The top of the mattress 2 defines a support surface 3 for receiving a patient, not shown. On a part of the frame 1 extending downwards from the mattress 2, a first means 4 for feeding a cover 5 in the form of a textile web to the support surface 3 is provided. At a further downwardly extending part of the frame 1, a second means 6 for receiving the cover 5 is provided. The first 4 and the second means 6 are mounted below a level N defined by the support surface 3. The first 4 and the second means 6 has a first 7 and second receiver 8, respectively. A recorded by the first pickup 7 first part 9 of the cover 5 is wound on a first roller 10. A second part 11 of the cover 5 is fastened to a second roller 12 received by the second receiver 8. The reference ^symbol 13 denotes a control unit. Figure 2 shows schematically a reference operation of the support surface 3 with the device of Figure 1. A direction of rotation is denoted by the reference D. A length of the support ^¬ surface 3 is denoted by the reference numeral. 1 The cover is moved in the reference operation on the mattress 2 in a direction of movement R.

The function of the device is as follows:

To cover the mattress 2 with a length 1 corre sponding ^¬ section of the first part 9, the recorded on the second pickup 8 second roller 12 with ^{¬ means of} a conveyor not shown in the direction of rotation D is rotated counterclockwise. As a result of the rotation of the attached to the second roller 12 second part 11 is wound onto the second roller 12. At the same time, the portion of the cover 5 is unwound from the first roll 10 and mounted in the direction of movement R on the mattress 2. With the whole portion of the cover 5 on the mattress 2, the winding on the second roller 12 can be stopped and the reference operation can be completed.

The conveying means may be a crank connected to the second roller 12 via a drive for rotating the second roller 12. The crank may be connected to a shaft of the second receiver 8, to which the second roller 12 is attached. Instead of the crank an electrical ^¬ shear, pneumatic or hydraulic drive may be provided.

The first receiver 7 can be designed in the form of a trough into which the first roller can be placed. The first pickup 7 may also be a shaft or the like. be on which the first roller 10 can be added. The portion of the cover 5 is due to a rotation of the second roller 12 in

Direction of rotation D unwound from the first roller 10 and mounted in the direction of movement R on the support. It is also possible that the first roller 10 of the first receiver 7 with the second roller 12 is rotated synchronously with lengths of the wound on the second roller 12 and the unwound from the first roller 10 reference 5 correspond.

To avoid slippage or wrinkling of the cover 5 on the support surface 3, a clamping means not shown can be provided for generating a force acting on the reference 5 clamping force. The clamping force can z. Example, be generated by a predetermined tensile force is required for rolling the cover 5 of the first roller 10. If, during ^loading , the tensile force is exceeded by turning the second roller 12 in the direction of rotation D, the section of the cover 5 is fed to the mattress 2 under the action of the tensile force and pulled over it. By fixing the second roller 12 with regard to a rotation counter to the direction of rotation D, the tension caused by the tensile force also after the reference operation ^¬ be maintained. The clamping force can also be generated in that the first 10 and second roller 12 are fixed with respect to a rotation after the reference and the first 7 and / or the second transducer 8 are vertically ^¬ lowered. To generate the clamping force, it is also possible to fix the first roller 10 and to further rotate the second roller 12 in the direction of rotation D by a predetermined amount. It can also be provided an additional deflection roller. The deflection roller can be moved after fixing the first 10 and second roller 12 such that in the longitudinal direction of the reference 5, a voltage is generated.

By means of a sensor means, not shown, the state of loading of the support surface 3 of the patient bed can be detected. In the sensor means may, for. B. act to a pressure sensor. It is also possible to determine the occupancy state by means of a camera. The detected assignment ^status can be supplied to the control unit 13. If the support surface 3 is occupied, the funding from the

Control unit 13 is automatically deactivated, so that a Ausfüh ^¬ ren of the reference process is not possible. In addition, the camera can also be used to monitor the reference process. the. The first 4 and / or the second means 6 may also include detecting means, not shown, for detecting an amount of the cover received on the first 10 and / or second roller 12. For example, the diameter of the first and / or second roller, including the first 9 and / or second part 11 received thereon, can be determined with the detection means. The diameter can be used as a measure of the amount of the cover. The diam ^¬ ser can also be used to determine the reference length of the first 9 and / or the second part. 11 Furthermore, the reference length can be determined with an impeller over which the cover 5 is guided. The impeller rolls during the reference ^¬ process on the cover 5, wherein the reference length can be determined from the Um ^¬ beginning of the impeller and the number of revolutions. To determine the reference length, optically, electrically or magnetically detectable markings can also be provided on the cover. As a measure of the amount of the cover, the weight of the first 10 and / or second roller 12 with the first 9 and second part 11 received thereon can also be used.

Exceeds the received on the second roller 12 amount of the reference a predetermined value so can, for. Example, by means of the control unit, the funding are blocked, so that no further reference operation can be performed. Similarly, the conveyor can be blocked if the recorded on the ers ^¬ th roller 10 amount of the reference falls below a predetermined value. This can z. Example, be the case when the reference length of the recorded on the first roller 10 first part 9 is smaller than the length 1, which is required for at least one reference operation. When exceeding or exceeding the predetermined value, a warning can be generated by means of a warning generating means. The War ^¬ voltage can be delivered from the warning generating means, visual and / or audible warning.

For controlling and / or monitoring the first means 4, the second means 6, the tensioning means, the conveying means, the Sensor means of the detection means and / or the warning generating means, the control unit 13 may be used. A computer may also be provided for the same purpose. With the control unit 13 or the computer, the reference process can be automated. To perform the necessary in Obtaining operations such. As an activation of the conveyor, a clamping of the cover 5, etc., can also be a manu ^¬ ell operated hand control such. As a remote control, be provided.

In a device such. B. a hospital and the like. , the computer or the control unit 13 may be connected to a central computer via a data network. The central computer can record occupancy statuses, the quantities of remuneration and the like. The reference operations can centrally controls ge ^¬ and coordinated. The recorded quantities of Be ^¬ trains can be used for purposes of storage or stockpile for covers 5.

Figures 3 to 5 show schematically the operation of a mobile changing device 14. The changing device 14 has an operating unit 15 and a mounted on a telescopic arm 16 movable pickup device 17. The Be ^¬ reference symbols v and h denote a vertical and hori- zontal direction a.

By means of the operating unit 15, the telescopic arm 16, the pick-up device 17 and a drive device (not shown) for moving the changing device 14 can be controlled by a user. The pickup device 17 can be moved with the telescopic arm 16 in the vertical direction v. Further, the telescopic arm 16 can be moved up and down in the horizontal direction h. A movement of the telescopic arm 16 and the pick-up device 17 may be mechanical, electrical, pneumatic, or hydraulic. For power supply of the changing device 14 may be an energy source, such. As a battery or a fuel cell can be provided. Upon removal of the second roller 12 from the second receiver 8 with the changer device 14, as shown in FIG. 3, this is positioned on the second means 6 in a first step. Subsequently, the pickup device 17 is brought by means of a movement in the vertical v and / or the horizontal direction h in a suitable for receiving the second roller 12 position. In a second step, the second roller 12 of the pickup device 17, z. B. a gripper, recorded as shown in Figure 4. After removing the second roller 12 from the second pickup 8, the pickup device 17 with the second roller 12 received thereon is brought into a transport position suitable for transport with the changing device 14 by pulling the telescopic arm 16 into a position as shown in FIG. Feeding a second roller 12 without a ^cover 5 wound thereon on the second receiver 8 can likewise be carried out with the changing device 14. In this case, the pickup device 17 with the empty second roller 12 received thereon is positioned on the second means 6 and on the second pickup 8 and the second roller 12 is fed on the second pickup 8. Removal of an empty first roll 10 and feeding of a first roll 10 with a cover 5 wound thereon can be analogous.

With the embodiments of the invention described above, the reference of the support surface 3 can be much easier ^¬ who. Instead of throwing over, spreading and re-tensioning the bearing surface 3 with a conventional bed sheet, the cover 5 with the device according to the invention need only be conveyed further by at least the length 1. This can be done auto ^¬ matically or largely automated. The labor and time required to obtain the support surface can be significantly reduced.
