Description

[0001] The invention relates to a device for raising persons lying on the ground according to the preamble of claim 1.

[0002] It is often difficult to raise someone who is lying on the ground and unable to stand up on their own. For example, a common approach involves using stretchers that are placed next to the person lying on the ground. The person is then placed on the stretcher by helpers, who then transport the person to a table, for example, to be raised. This procedure is very cumbersome and time-consuming.

[0003] The "Hebix" stand-up aid, which won design awards in 2014 (press release from the Mia Seeger Foundation), allows a person lying down to be supported by just one additional person. When unfolded, it is placed under the bent legs of the person who has fallen, who is then lifted into a sitting position. The stand-up aid has a seat made of straps.

[0004] From US 8 745 791 B1 a standing-up device is known which has two skid-shaped supports and a seat surface with the aid of which a lying person can be made to sit.

[0005] In another erection device (WO 2014 / 063 705 A1), the seat is mounted on a cross member to which side parts are attached on both sides, which are used as runners for erecting.

[0006] The invention is based on the object of designing the generic device in such a way that it can be used to easily raise people lying on the ground on the spot.

[0007] This object is achieved in the generic device according to the invention with the characterizing features of claim 1.

[0008] The device according to the invention has a plate-shaped support to which the side parts are hinged. The hinges are located at the opposing edges of the support. This makes it possible, when the device is not in use, to pivot the side parts relative to the support into a rest position. If the side parts are pivoted out, they are secured in this position by the locking element against pivoting back. This locking element also serves as a seat for the person being erected. Using the support element, the device can be adjusted from its initial position, in which the person is still on the ground, to the upright position, in which the person sits upright on the seat surface of the locking element.

[0009] In an advantageous embodiment, the side panels are plate- or frame-shaped. This provides them with high stability and load-bearing capacity. When the device is in use, one end of the side panels rests against the support. If the side panels are advantageously frame-shaped, they are lightweight. This also makes the entire device lightweight, allowing for easy transport.

[0010] To facilitate the erection process, the side panels are each equipped with at least one bearing housing for one support element on the edge area facing away from the support. Two support elements are then available for erecting the device, facilitating the erection process. The support elements are optimally guided in the bearing housings.

[0011] In an advantageous embodiment, the bearing housings have an outer side facing away from the support, which lies flush with the adjacent section of the end face of the side parts. This arrangement of the bearing housings on the side parts results in a large support surface when the device is placed on the ground with this outer side of the bearing housing and the end face sections of the side parts in order to raise the person lying on the ground. The enlarged support surface thus ensures a stable position of the device during the initial phase of the raising process.

[0012] Advantageously, the bearing housings are also attached to the side panels in such a way that one end face is flush with the upper end face of the housing panels. This creates an enlarged support surface for the locking element, ensuring that the person sitting on the locking element is reliably supported.

[0013] To facilitate the standing process, the end of the side parts facing away from the wearer is advantageously provided with at least one curved end section. For the standing process, the device is placed on the floor so that the end of the side parts facing away from the wearer rests on the floor. The curved end section then makes it easy to pivot the device upwards using the support parts to raise the person to a standing position.

[0014] It is advantageous if the curved end section is located between at least two straight end sections of the side parts. For example, one straight end section is advantageously provided at the height of the bearing housings so that at the start of the erecting process, the device rests on the ground with the outer sides of the bearing housings facing away from the support and these straight end sections of the side parts. This allows the device to be easily positioned opposite the person to be erected. The erecting process then begins when the device is pivoted upwards with the support parts. As soon as the side parts come into contact with the ground with the curved end section, the device can be easily moved upwards. The other straight end section forms the end section with which the side parts rest on the ground when the person is fully erected.Due to the straight design of these end sections, the device is securely supported on the ground without any fear of the device tipping back.

[0015] In another advantageous embodiment, the side parts are connected to the support parts. This results in a very simple, cost-effective device.

[0016] It can be advantageous if the side parts are formed integrally with the support parts. Since the support parts are rod-shaped, the side parts that are hinged to the support can also be formed from corresponding rod sections in a one-piece design. This makes the device very lightweight, which makes it considerably easier to handle. Furthermore, such a design contributes to the cost-effective production of the device.

[0017] To ensure easy erection of the device in this case, the side panels are preferably curved from their point of attachment to the support. These curved side panels allow the operator to easily erect the device from its initial position on the ground.

[0018] In an advantageous design, the locking element is hinged to the support. This ensures that the locking element is always available when the device is in use. If the locking element is a separate part, there is a risk that it will not be present during use. Because the locking element is hinged to the support, it can be pivoted from a use position to a rest position, where the locking element is not obstructive and requires minimal installation space.

[0019] The barrier element is advantageously designed as a plate. This offers high strength and load-bearing capacity. Since the person being raised is supported while sitting on the barrier element, the plate-shaped design of the barrier element provides optimal support for the person being raised during the lifting process.

[0020] Advantageously, the locking element is provided with open-edged recesses through which the support parts protrude. Thus, the locking element does not interfere with the operation of the support parts.

[0021] Advantageously, the support elements are secured against displacement in one direction by at least one locking device. This makes it possible to move the support elements in the other direction into the desired position. In the opposite direction, the locking device prevents the support elements from being pushed back. This design advantageously makes it possible to use the support elements to support the device, along with the person sitting on it, on the ground after it has been erected. The person's body weight therefore does not cause the support elements to retract.

[0022] A structurally simple design for the locking device is achieved by having a locking disc with an opening for the support member to pass through. This support member has an outer diameter that is smaller than the diameter of the opening in the locking disc.

[0023] In such a design, the locking disc is advantageously pivoted under a locking force in such a way that the locking disc rests with the edge of its opening on the support part and locks the support part against displacement in one direction.

[0024] When the locking disc is pivoted, the axis of its opening is no longer aligned with the axis of the support part. This prevents the support part from moving relative to the locking disc.

[0025] Advantageously, the locking disc is pivotally mounted on a holding part that is fastened in the bearing housing.

[0026] To generate the locking force, a spring is advantageously used, which pivots the locking disc relative to the retaining part. The locking disc is connected to the retaining part in such a way that the locking disc is positioned at an angle to the support part under the spring force. In this case, the axis of the opening in the locking disc forms an angle with the axis of the support part.

[0027] To allow the support element to be moved relative to the locking disc, the disc is adjusted using a handle against the locking force. The handle pivots the locking disc so that the axis of its opening coincides with the axis of the support element. Since the diameter of this opening is slightly larger than the outer diameter of the support element, the support element can be easily adjusted. As soon as the handle is released, it automatically pivots back into the locked position under the locking force, in which the axis of its opening is at an angle to the axis of the support element.

[0028] Advantageously, a support arm is hinged to each of the support parts, allowing the device to be securely supported on the ground in the upright position, together with the side parts. The support arms are provided in particular in a device in which the side parts are connected to the support parts and, in particular, are formed integrally with them.

[0029] The support arms are advantageously spring-loaded toward a stop provided on the support part. This allows the support arms to pivot automatically into their support position, allowing the operator to easily erect the device with the person being erected. Once the device has reached its upright position, the support arm can pivot automatically into the stop position and thus into the support position due to its spring loading.

[0030] The support arms are advantageously single-armed levers, which are hinged at one end to the support part or its side part.

[0031] To ensure that the support arms can be pivoted reliably, they are advantageously positioned on a side surface of the support part or the side part.

[0032] The pivot axis of the support arms runs horizontally relative to the upright position of the device. The support arms extend diagonally from the pivot axis toward the ground relative to the upright position of the device. The support arms and the lower adjacent part of the side parts or support parts diverge, ensuring secure support of the device in the upright position.

[0033] To facilitate the erection process, a transversely projecting handle is advantageously provided at the free end of the support members. The handles are preferably rotatable about their axis.

[0034] The subject matter of the application arises not only from the subject matter of the individual patent claims, but also from all information and features disclosed in the drawings and the description. Even if they are not the subject matter of the claims, they are claimed as essential to the invention insofar as they are novel, individually or in combination, over the prior art.

[0035] Further features of the invention emerge from the further claims, the description and the drawings.

[0036] The invention is explained in more detail with reference to several embodiments shown in the drawings.

[0037] This device allows a person lying on the floor to be raised to a sitting position. It provides a standing aid that is particularly suitable for frail or mobility-impaired individuals. With this device, such individuals can be effortlessly transferred from a resting position to a sitting position by just one person. This device can be used in nursing homes, retirement homes, hospitals, emergency services, and similar settings.

[0038] To make the device easy to transport, it is designed to be foldable. Fig. Figure 1 shows the device in the folded state. It has a support 1, which is advantageously designed as a plate. It advantageously has a square, in particular rectangular outline. In the area of ​​each of the two long sides 2, 3 of the support 1, a side part 4, 5 is hinged. The side parts 4, 5 are of the same design and advantageously have a plate shape. To save weight, the side parts 4, 5 are each provided with a recess 6, 7. The side parts 4, 5 are hingedly connected to the long side 2, 3 of the support 1 by a long side 8, 9. The side parts 4, 5 have the same length in the area of ​​their long sides 8, 9 as the support 1 in the area of ​​its long sides 2, 3.

[0039] As from Fig. 3, the side parts 4, 5 can be folded out about their axes 10, 11 extending in the direction of their long sides 8, 9 until they rest with their end faces 12, 13 on the side surface 14 of the carrier 1 ( Fig. 3).

[0040] To form the pivot axes 10, 11, the side parts 4, 5 are hinged to the support 1. For this purpose, a bearing block 15, 16 is attached to the side surface 14 of the support 1, into which the side parts 4, 5 engage with corresponding joint parts 17, 18. The bearing blocks 15, 16 and the joint parts 17, 18 extend only over part of the longitudinal sides 2, 3 of the support 1 and the side parts 4, 5, respectively.

[0041] To relieve the load on the pivot axes 10, 11, the side parts 4, 5 are provided with bearing blocks 19 to 21 in the area above and below their joint parts 17, 18, the end faces of which rest against the two end faces of the bearing blocks 15, 16 of the support 1. The bearing blocks 19 to 21 are attached to the inside of the side parts 2, 3.

[0042] The two side parts 4, 5 can be folded out of their position according to Fig. 1 by pivoting around the axes 10, 11 into the operating position according to Fig. 3 can be pivoted outwards. In this position, the side parts 4, 5 rest flat against the side surface 14 of the support 1 with their end faces 12, 13. In this position, the side parts 4, 5 extend perpendicular to the support 1.

[0043] To prevent the side parts 4, 5 from folding back, at least one locking element 22 is provided on the carrier 1. It is advantageously designed as a locking plate, which is located on the side of the carrier 1 facing away from the side parts 4, 5 and from which Fig. 1 to 3 shown rest position into the locked position according to Fig. 4 can be pivoted. The locking element 22 has an approximately rectangular outline and is hinged by an edge 23 to an edge 24 of the carrier. In the Fig. In the locked position shown in Figure 4, the locking element 22 rests on the end faces of the two folded-out side parts 4, 5. For locking the locking element 22, a latching mechanism can be provided, for example. In the preferred and illustrated embodiment, such a locking mechanism is not provided. The locking element 22 serves as a seat when the person stands upright, so additional locking of the locking element 22 is not necessary.

[0044] The side parts 4, 5 are each provided with a bearing housing 25, 26 at their free end facing away from the carrier 1, through which a support part 27, 28 protrudes. The bearing housings 25, 26 are fastened to the mutually facing inner sides of the side parts 4, 5 such that their end faces 29, 30 are level with the end faces 31, 32 of the side parts. The locking element 22 is in the locking position according to Fig. 4 on the end faces 29, 30 of the bearing housings 25, 26 and on the end faces 31, 32 of the side parts 4, 5. The locking element 22 is also designed such that it does not protrude laterally beyond the side parts 4, 5.

[0045] The outer side 33, 34 of the bearing housings 25, 26 facing away from the carrier 1 is aligned with the front end face 35, 36 of the side parts 4, 5. As a result, the bearing housing 25, 26 does not protrude beyond the side parts 4, 5.

[0046] The support parts 27, 28 extend through the bearing housings 25, 26, in which corresponding guides for the support parts are provided. They are advantageously rod-shaped and have a round cross-section. The support parts 27, 28 are advantageously telescopic rods. They can be displaced relative to the bearing housings 25, 26. In the illustrated embodiment, the support parts 27, 28 each have an outer tube 37, 38, into which an inner tube 39, 40 engages ( Fig. 4). In the position according to Fig. 4 the inner tubes 39, 40 are retracted into the outer tubes 37, 38. Fig. Figure 5 shows the inner tubes 39, 40 in their fully extended position. The inner tubes 39, 40 are provided with a longitudinal groove 41 into which a screw 42 engages, which is located near the Fig. 5 are screwed radially into the outer tubes 37, 38 at their upper ends. The screws 42 extend into the longitudinal groove 41 and ensure that the inner tubes 39, 40 can only be moved axially, but not rotated about their axes. A grip sleeve 43, 44 is placed on the free ends of the inner tubes 39, 40. At the lower end, the outer tubes 37, 38 are provided with a detachably attached buffer 45, 46, with which the support parts 27, 28 are braced on the floor. In the fully extended position, the inner tubes 39, 40 are fixed by a locking spring 70 provided in the outer tube 37, 38. To push the inner tubes 39, 40 back into the outer tubes 37, 38, the locking spring 70 must be pressed to release the fixation or locking. Such locking springs are known and therefore will not be described in detail.

[0047] In principle, it is also possible to design the inner tubes 39, 40 in such a way that they can be locked or fixed in any position (with continuous adjustment) or in several extended positions.

[0048] The support parts 27, 28 protrude over the bearing housings 25, 26 as well as over the locking element 22. It is provided on its free edge 47 with an open-edged recess 48, 49 through which the support parts 27, 28 protrude. The recesses 48, 49 also ensure that the locking element 42 is in its locking position according to Fig. 5 can be swiveled.

[0049] The support parts 27, 28 can be secured against displacement in any direction in any extended position. For this purpose, a locking device 50 is provided in the bearing housings 25, 26, which is Fig. 8 to 12. It has a locking disc 51 provided with a central opening 52 through which the outer tube 37, 38 of the support part 27, 28 protrudes. The locking disc 51 is held by a retaining bracket 53, on which the locking disc 51 is mounted with limited pivoting capability. The retaining bracket 43 has an opening 55 on one of its legs 54, through which the outer tube 37, 38 of the support part 27, 28 protrudes. The diameter of the opening 55 is larger than the outer diameter of the outer tube 37, 38. The free end of the locking disc 51 is pivotally mounted on the other leg 56, which runs at a right angle to the leg 54. This leg 56 is at a radial distance from the outer tube 37, 38.

[0050] On the side of the locking disc 51 facing away from the leg 54 of the bracket 53, a helical compression spring 57 engages, which surrounds the outer tube 37, 38 and is supported on a corresponding stop within the bearing housing 25, 26. The helical compression spring 57 loads the locking disc 51 toward the leg 54 of the bracket 53. This causes the locking disc 51 to pivot about its pivot point on the bracket leg 56 toward the leg 54 of the bracket 53. The opening 52 provided in the locking disc 51 has a diameter which is slightly larger than the outer diameter of the outer tube 37, 38. The pivoting of the locking disc 51 results in the outer tube 37, 38 being clamped at the edge of the opening 52, which prevents the outer tube 37, 38 from being held in the position according to the Fig. 8 and Fig. 9 can be pushed upwards.

[0051] If the support parts 27, 28 are to be moved in this direction relative to the bearing housings 25, 26, this clamping between the opening edge and the outer tube 37, 38 must be released. A handle 58, which is advantageously formed integrally with the locking disc 51, is used for this purpose. To release the locking, the handle 58 is pressed in the direction of arrow 59, whereby the locking disc 51 is pivoted against the force of the helical compression spring 57 relative to the retaining bracket 53. The locking disc 51 is thereby released from its clamped position ( Fig. 8) in which it forms an acute angle with the axis of the outer tube 37, 38, into a release position in which the locking disc 51 is perpendicular to the axis of the outer tube 37, 38. The axis of the opening 52 of the locking disc 51 then lies in the axis of the outer tube 37, 38. The support part 27, 28 can then simply be moved upwards into the desired position. As soon as the handle 58 is released, it automatically pivots upwards again under the force of the helical compression spring 52 into the Fig. Locking position shown in Figure 8.

[0052] If, however, the support parts 27, 28 are pressed downwards, the friction between the edge of the opening 52 and the outer tube 37, 38 ensures that the locking disc 51 is moved into the release position according to the Fig. 9 and Fig. 11 is pivoted so that the outer tube 37, 38 can be moved into the desired position. As soon as the support part 27, 28 is no longer subjected to downward displacement force, the locking disc 51 pivots back into the locking position under the force of the helical compression spring 57 in accordance with Fig. 8 and Fig. 10.

[0053] The locking device 50 is designed such that the locking of the support parts 27, 28 against upward displacement becomes more effective the higher the force acting on the support parts 27, 28 in this direction.

[0054] The articulated connection between the locking disc 51 and the leg 56 of the holding bracket 53 is made by a pivot bearing, which is known per se and is therefore not explained in more detail.

[0055] The retaining bracket 53 is fixed inside the bearing housing 25, 26. The locking disc 51 is provided in the bearing housing 25, 26 such that the handle 58 protrudes from the bearing housing ( Fig. 7). To enable the handle 58 to be operated, the side parts 4, 5 are each provided with an opening 60, 61 at the level of the handle 58. In the operating position of the device, the handles 58 are located on the facing inner sides of the side parts 4, 5. The openings 60, 61 are sufficiently large to enable the handle 58 to be operated from the outside.

[0056] In Fig. 12 shows the two positions of the locking disc 51. In the release position, the locking disc 51 is perpendicular to the axis 62 of the outer tube 37, 38. This release position is in Fig. 12 is marked with I. In the locking position II, the locking disc 51 is pivoted slightly upwards under the force of the helical compression spring 57 in the direction of the leg 54 of the holding angle 53, so that the locking disc 51 forms an acute angle α with the axis 62.

[0057] Based on Fig. 13 describes how a person lying on the ground 63 can be raised using the device. The device is first moved from the folded position according to Fig. 1 folded into the operating position as shown in Fig. 4. The device is then placed on the floor so that the plate-shaped support 1 is spaced from the floor and the locking element 22 faces the person 63. In this position, the device rests on the floor with the side parts 4, 5. The support parts 27, 28 are displaced so that the buffers 45, 46 rest on the floor 64, 65 of the bearing housing 25, 26 ( Fig. 6). In order to be able to carry out this displacement movement of the support parts 27, 28, the handles 58 are actuated in the manner described in order to release the locking of the support parts against displacement in this direction.

[0058] The device is positioned so that the extended support parts 27, 28 are arranged in the area of ​​the person 63 lying on the floor. Then the legs are bent and the device is positioned so that the lower legs rest on the plate 1 and the thighs on the locking plate 22 ( Fig. 13a). In this position, the device rests on the floor with its narrow end faces 35, 36 and the outer sides 33, 34 of the bearing housings 25, 26. Since the bearing housings 25, 26 are attached to the inner sides of the side parts 4, 5 in such a way that the outer sides 33, 34 and the adjacent end faces 35, 36 of the side parts 4, 5 lie in a common plane, a relatively large support surface is created for the device. It is therefore held securely in this position. The center of gravity of the device is positioned such that the device can be moved from the position shown in Fig. 13a cannot pivot automatically towards an upright position.

[0059] The two end faces 35, 36 of the side parts 4, 5 have different sections. At the level of the bearing housings 25, 26, the end faces 35, 36 are straight (35a, 36a). These straight sections merge into a continuously curved section 35b, 36b ( Fig. 4). It connects the straight section 35a, 36a with another straight section 35c, 36c, which runs at an obtuse angle to the section 35a, 36a. It finally connects to an end section 35d, 36d, which is perpendicular to the straight section 35a, 36a and connects at a right angle to the rear end face 66, 67 of the side parts 4, 5 ( Fig. 4).

[0060] As soon as the person 63 is in the position according to Fig. 13a, the entire device is erected together with the person 63 using the support parts 27, 28. The device "rolls" over the curved end sections 35b, 36b until the device rests on the ground with the straight end sections 35c, 36c ( Fig. 13b). In this position, the support parts 27, 28 can be pushed down until they rest on the floor with their buffers 45, 46. The device can then easily be moved into the final position according to Fig. 13c, in which the device rests on the ground with the straight end sections 35d, 36d. The support parts 27, 28 are thereby moved downwards so far that the device with the person 63 sitting on it is supported in a tilt-proof manner. Since the support parts 27, 28 are secured by the locking devices 50 against displacement in the upward direction, there is no danger of the device moving back towards the position according to Fig. 13a tilts. In the upright position according to Fig. 13c, the device acts like a chair on which the person 63 can sit comfortably.

[0061] The support parts 27, 28 are advantageously spaced apart such that they extend along the back of the person 63 being erected. The person is thus supported on the back by the support parts 27, 28 during the erection.

[0062] The device is characterized by its simple and cost-effective production. It consists of only a few components, which can be folded and unfolded even by less experienced operators. No special locking devices are required for the side parts 4, 5. The plate-shaped locking element 22 prevents the side parts 4, 5 from pivoting back in the device's operating position. The support parts 27, 28 extend through the recesses 48, 49 of the locking element 22. Since the support parts 27, 28 extend through the bearing housings 25, 26 and these are attached to the side parts 4, 5, this results in a simple safeguard against the side parts 4, 5 pivoting back from their unfolded position. The device is easy to handle and requires no special expertise.When folded, the device takes up very little space and can therefore be easily transported, for example, in emergency vehicles. Since the side panels 4 and 5 have recesses 6 and 7, they are lightweight. The recesses 6 and 7 are so large that only a single surrounding frame is required on the side panels 4 and 5, resulting in a lightweight device.

[0063] The support parts 27, 28 cannot slip out of the bearing housings 25, 26. In one direction, this is prevented by the buffers 45, 46, which, as can be seen from Fig. 6, come into contact with the bottom 64, 65 of the bearing housings 25, 26. In the other direction of displacement, pushing through the bearing housings 25, 26 is prevented by a stop 68, 69 ( Fig. 1), which is formed by removable rings that are placed on the other end of the outer tube 37, 38. The screws 42 ( Fig. 5) which engage in the longitudinal grooves 41 of the inner tubes 39, 40.

[0064] The Fig. 14 to 17 show embodiments in which the plate-shaped side parts 4, 5 of the previous embodiment are formed by sections of the support parts 27a, 28a. Their ends 71, 72 adjoining the carrier 1 are curved in an arcuate manner. Fig. 17 shows, the curved ends 71, 72 extend over an angular range of almost 90°. The curved ends 71, 72 merge into straight sections 73, 74, which make up the remaining part of the support parts 27a, 28a. The transition of the curved ends 71, 72 into the straight support sections 73, 74 advantageously takes place at a distance from the locking position ( Fig. 17). This ensures that the locking element 22 in the locking position rests with its free edge 47 on straight areas of the support parts 27a, 28a.

[0065] The ends 71, 72 of the support parts 27a, 28a can each be rotated about mutually parallel axes 75 from the position of use according to Fig. 17 can be swung inwards into the rest position. Fig. 17, only one pivot axis 75 is visible. The pivot axes 75 are provided on bearing arms 76, 77 projecting transversely from the inside of the carrier 1. The pivot axes 75 are provided on the mutually facing sides of the support member ends 71, 72. The support members 27a, 28a can be pivoted inward about the axes 75 when the locking element 22 is in the rest position according to Fig. 1. This allows the device to be folded up very small for transport. In the upright position of the device ( Fig. 14d) the pivot axes 75 run vertically.

[0066] In the position of use, the support parts 27a, 28a advantageously rest with the end faces 78, 79 of their ends 71, 72 on the inside of the carrier 1 ( Fig. 17), whereby the axles 75 are relieved of load when transporting the person 63.

[0067] The locking element 22 is provided with at least one support 82, 83 on its underside in the region of its edges 80, 81 which adjoin the edge perpendicularly. They are fastened to the underside of the locking element 22 in such a way that they prevent its pivoting movement from the rest position according to Fig. 1 into the blocking position according to Fig. 17. In the locked position, the supports 82, 83 rest with their one ends on the support parts 27a, 28a, so that they are secured against pivoting back about the axis 75.

[0068] According to the previous embodiment, the locking element 22 is provided on its free edge 47 with recesses 48, 49, into which the support parts 27a, 28a engage in the position of use. As described with reference to the previous embodiment, this engagement reliably prevents the support parts 27a, 28a from being inadvertently pivoted about their axes 75.

[0069] The locking element 22 with the supports 82, 83 is designed so that in the locking position it lies flat against the outside of the support parts 27a, 28a, as in Fig. 17. As a result of this planar contact, the locking element 22 is secured in its locking position so that it cannot be pivoted under the weight of the person 63 sitting on it.

[0070] Preferably, however, the supports 82, 83 are attached to the support parts 27a, 28a and project perpendicularly from them. The supports 82, 83 then serve to support the locking element 22 in the locking position.

[0071] The two support parts 27a, 28a are of the same design. In the embodiment shown in Fig. 17 is formed by two plug-in parts 27a', 27a'' and 28a' and 28a'', which can be plugged together. When plugged together, the two parts are secured by a plug-in pin 84, 85 passing through each of the plug-in parts.

[0072] In another embodiment, the support parts 27a, 28a can also be designed as telescopic parts, which can then be continuously adjusted in length. The telescopic parts can be clamped or locked against each other in any adjustment position in a known manner.

[0073] The support parts 27a, 28a can also be formed integrally with the ends 71, 72. In this case, the length of the support parts 27a, 28a cannot be changed.

[0074] To ensure that the device is in the upright position ( Fig. 14d), support arms 86, 87 are pivoted to the two support parts 27a, 28a. They are single-armed levers which are pivotally connected to the support parts 27a, 28a near one end via an axis 88. The pivoting of the support arms 86, 87 is located approximately at the transition from the curved ends 71, 72 to the adjoining straight sections 73, 74 of the support parts 27a, 28a. When the device is unfolded, the pivot axes 88 are located close to the transition from the curved ends 71, 72 to the straight sections 73, 74 of the support parts 27a, 28a ( Fig. 17). The axle 88 extends through the support arms 86, 87 and the support parts 27a, 28a. Both the support arms and the support parts are each formed as hollow profiles. They advantageously have a square, preferably rectangular, cross-section. The axles 88 are held in the support parts 27a, 28a by a cross bolt 89.

[0075] The support arms 86, 87 are advantageously arranged on the opposite outer sides of the support parts 27a, 28a. The axes 88 protrude, as can be seen from Fig. 16, via the support arms 86, 87, which are axially secured on the axis 88 by at least one securing element 90, preferably a snap ring.

[0076] To ensure that the support arms 86, 87 can be reliably pivoted about the axis 88 relative to the support parts 27a, 28a, the support arms 86, 87 rest against the support parts 27a, 28a. It is also possible to provide a sliding disk or the like between the support arms and the support parts on the axes 88 to ensure reliable pivoting of the support arms 86, 87.

[0077] The support arms 86, 87 are spring-loaded in a pivoting direction. For this purpose, a torsion spring 91 is located within the support arm, one end 92 of which engages in a diametrical slot 93 of the axis 88, and the other end 94 of which rests against the inside of the support arm 86, 87. The spring 91 loads the support arm 86, 87 in a pivoting direction such that its longitudinal side 95 rests against a stop 96 provided on the support part 27a, 28a. The stop can be formed, for example, by a screw that is screwed into the support part 27a, 28a.

[0078] The torsion spring 91 loads the support arm 86, 87 in such a way that, when the person 63 is in an upright position, it forms an acute angle with the corresponding curved end 71 of the support part 27a. The curved support part end 71 and the corresponding support arm 86 thus diverge from the pivot axis 88 in the direction of the floor 97. The device is thereby securely supported on the floor 97 in the erected state. Since the support arms 86, 87 are spring-loaded towards their stop position, the support arm 86, 87 will in any case move from the position according to Fig. 14a into the support position according to Fig. 14d.

[0079] The erection of a person 63 lying on the ground 97 is carried out in basically the same way as with the aid of the Fig. 13a to 13c. The device is first unfolded and the two support parts 27a, 28a are secured by the locking element 22. The unfolded device is then positioned so that the support parts 27a, 28a are arranged in the area of ​​the person 63 lying on the floor. The legs of the person 63 are then bent and the device is positioned so that the lower legs rest on the plate 1 and the thighs rest on the plate-shaped locking element 22. This position is shown in Fig. 14a. The support arms 86, 87 rest with their free ends on the floor 97 under the force of the spring 91.

[0080] The device is then pivoted upward. The curved ends 71, 72 of the support members 27a, 28a come into contact with the floor 97, allowing the device to be moved upwards very easily. The device "rolls" along the floor 97 using the curved ends 71, 72. During this rolling movement, the support arms 86, 87 each rest on the floor 97 under spring force. This results in the support members 27a, 28a moving relative to the support arms 86, 87 as the device is pivoted upwards. This movement occurs counter to the force of the springs 91.

[0081] The ends 71, 72 of the support parts 27a, 28a are designed in such a way that the support arms 86, 87 can pivot back into their stop position under the force of the springs 91 as soon as the ends 71, 72 only rest on the floor 97 in their end region. Then the support arm 86, 87 can pivot under the force of the spring 91 in the illustration according to Fig. 14 counterclockwise until it rests against stop 96. The device is then securely supported on the floor.

[0082] In order for the support arms 86, 87 to be able to pivot into this stop position, the distance of the pivot axis 88 from the free end of the support arms 86, 87 is smaller than the vertical distance between the pivot axis 88 and the support side of the ends 71, 72 in the area of ​​their front sides 78, 79. The support arms 86, 87 can then pivot automatically into the stop position under the force of the springs 91 during the erection process as soon as the support arms 86, 87 are no longer in contact with the ground 97.

[0083] In the embodiment according to Fig. 17, the support parts 27a, 28a are advantageously each provided with a bow-shaped back support part 98, 99.

[0084] The support parts 98, 99 are provided on the mutually facing inner sides of the plug-in parts 27a'', 28a''. As Fig. As shown in Figure 17, the support parts 98, 99 are provided on the plug-in parts 27a'', 28a''. To raise the person 63 lying on the ground, the plug-in parts 27a'', 28a'' can simply be pushed under the person 63 and then inserted into the plug-in parts 27a', 28a' and secured with the plug-in pins 84, 85.

[0085] In order to easily raise the device with the person 63 to be lifted, without the person being lifted having to grasp the support parts 27a, 28a, a handle 100, 101 is provided near the free ends of the support parts 27a, 28a. In the illustrated embodiment, the handles are provided on the mutually opposite outer sides of the two support parts 27a, 28a. However, they can also be arranged on the mutually facing inner sides of these support parts. The handles 100, 101 protrude perpendicularly from the support parts 27a, 28a. Advantageously, the handles 100, 101 are rotatable about their axes. This makes the raising process much easier. After the person 63 to be lifted has been raised into the position according to Fig. 14a has been brought into relation with the device, the lifting person can comfortably erect the device using the handles 100, 101, as shown in the Fig.14b to 14d. Since the handles 100, 101 are provided at the free ends of the support parts 27a, 28a, the large lever arm allows the device with the person 63 sitting on it to be erected with relatively little effort. If the handles 100, 101 are also freely rotatable about their axes, the device can be erected particularly easily.
