Description

Badewannenlifter

The present invention relates to a bath tub lifter for lifting and lowering people, for example from and into a bath tub with a base plate and a seat element which can be moved relative to the base plate.

Bath tub lifters of this type are known and used on the market in a variety of forms and designs. They essentially serve as bathing aids for the elderly and especially disabled people. Conventional bath tub lifters are positioned and adjusted in bath tubs.

A seating element is extended approximately at the edge of a bathtub. Then the Sit the user on this seat, for example, from a wheelchair or such a seat aid. The bath water can already be embedded in the bath. The seat element is then sunk against the base plate by means of a drive device, the user thereby being immersed in the bathing water.

After bathing, the seat element can then be moved upward again with respect to the base plate and the user can be moved to an exit position over the edge of the bathtub.

A disadvantage of the conventional bathtub lifters available on the market is that they are often damaged in operation by the user being too heavy, and are difficult and expensive to dismantle if they are no longer used. In addition, these are expensive to buy and are difficult to trade. Furthermore, these are not always stable.

The present invention has for its object to provide a bathtub lifter of the type mentioned, which eliminates the disadvantages mentioned and with which the handling of such a bathtub lifter in operation and also for transport is to be considerably simplified and improved. In addition, long-term operation of the bath tub lifter with high security and stability should also be guaranteed.

To achieve this object, the seat element can be moved linearly relative to a base support and this can be pivoted relative to the base plate. In the present invention, the seat element can be moved linearly with respect to a base support, the base support being mounted so as to be pivotable relative to the base panel, in particular via a base plate.

This pivoting of the base plate relative to a sliding carriage mounted movably in the base plate and the pivoting of the base carrier relative to the base plate ensures that at the same time an inclination of the backrest is ensured when the seat element is lowered.

The seat element can be moved linearly along the base support by means of a carriage which is driven by a drive device. This drive device is not only articulated to the slide, but also to the base plate. Furthermore, a seat plate is pivotally mounted relative to a backrest.

After the seat plate has been completely lowered relative to the base support, the base support with the slide and also with the drive device can be inclined backwards by a definable angle, the seat base being decoupled from this movement. This remains approximately parallel to the base plate. The seat element can thus be moved into the bathtub against the base plate and then the backrest of the seat element and the base support itself, which moves the seat element up and down, can be pivoted backwards. The drive device is also tilted backwards. If the bathtub lifter is no longer used, the base carrier is moved back to its original starting position, then the seat element is raised slightly and the seat plate is pivoted against the backrest.

Then the base plate fixed in the base plate, which is articulated in relation to the sliding carriage, is moved out of an end locking groove of the base plate by shifting, then pivoted about a joint between the base plate and sliding carriage, preferably by about 90 °, until the base carrier is approximately parallel to Base plate lies. Then the seat plate and backrest between the base frame and base plate are folded together. The basic carrier with the subsequent base plate can then be moved back over the sliding carriage against an end face of the base plate in order to maintain its overall very short transport length.

In particular, these unique possibilities of movement of the base carrier, which on the one hand can be tilted backwards, on the other hand carries the slide for the seat element and on the other hand can be folded relative to the base plate to achieve a transport position, characterize the present invention. At the same time, the drive device can be tilted backwards in accordance with the base support and can also be folded down relative to the base plate.

In a further preferred exemplary embodiment, a bath tub lifter is shown, in which in particular a tilting movement of the base support relative to the base plate, in particular a base plate by means of latches and Rocker arm secures while the seat element can be moved along the base support. Only when the seat element is in a lowered position is the seat plate placed on the base plate, in which position the slide, in particular rollers of the slide, are secured by means of the rocker arm. The slide is thus secured against linear movement along the base support. A corresponding rocker arm releases a bolt in this position, which allows the base support to move relative to the base plate to tilt. During the tipping and in the tipped state, the slide, in particular the seat element, remains secured against linear movement along the base support.

Another special feature of the present invention is that the base support and base plate are formed in two parts, with a base plate adjoining the base support at the end, which engages in a corresponding recess in the base plate by means of a latching lug and, on the other hand, can be detached from the base plate using any locking device, in particular by means of a bolt lock is set. In this way, the bathtub lifter can be quickly and easily disassembled into two parts, which is particularly advantageous during transport, so that the individual parts are easier to transport. Furthermore, can be centered and aligned very easily and easily in a bathtub floor during assembly or. Only after this process can the base carrier with the seat element and drive device be inserted into the base plate again. This should also be within the scope of the present invention.

According to FIGS. 1.1 and 1.2, a bath tub lifter R is shown for lifting and lowering people, in particular handicapped or handicapped people, into or out of a bath tub.

Here, the bath tub lifter R has a base plate 1, which is preferably secured via four suction cup-shaped duck feet 2 on a bath tub floor against slipping and possibly tilting. A base plate 3 is mounted in the base plate 1, to which a base support 5 is pivotably connected about a joint 4. A slot 6 is formed in the base support 5, in which a slide 7 can be moved back and forth in the double arrow direction X shown. On the rear side adjoins the base body 5, a drive device 8, which is connected to the base plate 3 in an articulated manner at one end and, at the other end, is in engagement with the slide 7, as is not shown in detail here.

Connected to the carriage 7 is a seat element 9, which is formed from a seat plate 11 which can be pivoted about a joint 10 relative to the carriage 7 and a backrest 12 which is firmly connected to the carriage 7. The seat plate 11 can be pivoted about the joint 10 against the backrest 12. In the exemplary embodiments shown, the bath tub lifter R is shown in an extended position of use. In this position of use, a user can sit on the seat element 9 and then be lowered into a bathtub for bathing, for example.

FIGS. 1.3 and 1.4 show that a sliding carriage 13 is pivotably connected to the base plate 3 so that it can pivot about the joint 4.

The sliding carriage 13 is arranged to be displaceable along the double arrow direction Y shown within the base plate 1, as is also shown in particular in FIGS. 6.1 to 6. 6.

It can also be seen from FIG. 1.4 that the base support 5 can be pivoted about the joint 4 by an angle α about the joint 4 relative to the base plate 1, in which case one Guide groove 14 of the base plate 3 of the base support 5 is guided and limits a pivoting movement.

It can also be seen from FIG. 1.3 that the drive device 8 is formed from two cylinder elements 15.1, 15.2 which can be moved relative to one another, the cylinder element 15.1 being connected to the slide 7 and the cylinder element 15.2 being articulated to the base plate 3, in particular being pivotably connected.

The drive device 8 can be operated as a cable pull element, spindle electromechanically or hydraulically. There is no limit to the present invention.

A fully extended position of the seat element 9, in particular of the slide 7, is shown in FIGS. 1.1 to 1.7, a maximum stroke H thereby being achieved. In FIG. 1.5 it is indicated that the drive device 8, in particular its cylinder element 15.2, is pivotably mounted about a joint 16 and that the carriage 7 engages with the cylinder element 15.1 of the drive device 8 via a driver 17. Corresponding rollers 18 support the slide 7 in guide grooves 19 of the base support 5.

Furthermore, the slide 7 is adjoined by a pivotally mounted clamping element 20, which can be moved in a pin track 21 within the slot 6 of the base support 5. The clamping element 20 also forms a stop for a seat plate extension 21 around the seat plate 11 in an approximately parallel position Base plate 1, in particular to define a surface.

Furthermore, the base plate 3 is assigned a nose-like guide element 22 approximately in the center. In this fully extended position, the base body 5 is fixed relative to the base plate 3 by means of a locking device 23, so that the base body 5 cannot be pivoted about the joint 4 along the guide groove 14.

In this position of use, as is also shown in FIG. 1.9, for example, the base plate 3 is fixed in the base plate 1, in which the sliding carriage 13 with the base plate 3 can be moved against an end face 24 of the base plate 1 and an end-side locking element 25 in one Appropriate, matching, frontal locking groove 26 of the base plate engages and thereby pivoting of the base plate 3 around the joint 4 with the sliding carriage 13 is prevented.

In this position, the base plate 3 can be releasably secured against displacement with respect to the base plate 1 by means of a locking bolt or the like (not shown here).

If the base support 5 and the adjoining base plate 3 are to be given away about the joint 4 relative to the sliding carriage 13 in order to fold the bath tub lifter R, the sliding carriage 13 is moved somewhat to the left, so that the latching element 25 extends out of the latching groove 26. The base body 5 with base plate 3 is then pivoted about the joint 4 in such a way that that according to FIGS. 6.1 and 6.2 the base support 5 is approximately parallel to the base plate 1. In order to reduce the overall transport length of the bath tub lifter, it is possible to move the sliding carriage 13 against the end face 24 of the base plate 1 after folding or during the folding, in particular after the locking element 25 has reached over the area of the base plate 1. Thus, after the base plate 3 has been pivoted out in the end region of the latching element 25, the joint 4 then moves against the end face 24 from the base plate 1, thereby considerably reducing the overall length of the bath tub lifter R in the folded state according to FIGS. 6.1 and 6.2.

In the exemplary embodiment according to FIG. 1.8, a partial longitudinal section according to FIG. 1.5 is shown on an enlarged scale. The seat plate arm 21 of the seat plate 11, which is articulated about the joint 10 of the carriage 7, is in engagement with the clamping element 20, which is pivotably mounted about a cardan shaft 27, also for receiving the rollers 18. This clamping element 20, which is pivotally mounted about the drive shaft 27, is preferably supported at one end at right angles to the seat plate extension 21 and is on the other hand via a pin groove 28, which runs approximately parallel to the guide groove 19 for receiving the rollers 18 within the base support 5 protruding pin element 29 guided linearly.

In the figures 2.1 and 2.2, the seat element 9 is shown in a final phase of lowering to the base plate 1. In this case, when the seat plate 11 of the seat element 9 is completely lowered, the face lies on an elevation 30 of the base plate 1 and is stored there, as is also shown in FIG. 2.6. In this position, the drive device 8 is retracted or the two cylinder elements 15.1, 15.2 are retracted into one another. Here, as is particularly shown in FIGS. 2.3 and 2.4, the seat plate extension 21 of the seat plate 11 is connected to the clamping element 20 and is still pressurized.

The carriage 7, in particular its joint 10, is arranged somewhat higher than the joint 4 between the base plate 3 and the sliding carriage 13.

It can also be seen from FIG. 2.3 that in this position the cardan shaft 27 engages over the guide element 22 at its nose-like tip.

Furthermore, the cardan shaft 27 with the roller 18 reaches an end region of the guide groove 19 in which the locking device 23 is located. In this position, the locking device 23 is still locked and blocks a pivoting movement of the base body 5 relative to the base plate 3 along the guide groove 14 around the joint 4.

In the exemplary embodiment according to FIG. 2.5, in particular the area of the drive device 8 is shown enlarged. The drive device 8 preferably consists of a pulley-like drive, the two cylinder elements 15.1, 15.2 being guided one inside the other. In this case, a first roller set 31.1 is mounted in the cylinder element 15.1 and a second roller set 31.2 is stored in the second cylinder element 15.2, which is movably guided within a roller slot 32. The roller packs 31.1 and 31.2 are connected to one another in the manner of a block and tackle by means of a wire, line or the like, which is not shown here.

The peculiarity of the present drive device 8 here is that by shortening the line, for example by means of a servo or electric motor, which is not shown in more detail here, it moves apart

Cylinder elements 15.1, 15.2 is made possible. This ensures lifting, in particular moving the slide 7 upwards along the base support 5. It should be pointed out once again that the present invention does not refer to this in any way

Drive device 8 limited. There are others too

Drives conceivable, such as a spindle, a hydraulic or pneumatic cylinder or the like. Electromechanical

Drives.

FIGS. 3.1 to 3.5 show and describe a control phase as a further position of use of the bath tub lifter R.

By further lowering, as is particularly shown in FIG. 3.4, the propeller shaft 27 bears against the guide element 22, the clamping element 20, which is partially indicated by dashed lines, strikes the pin groove 28 at the end with its pin element 29 and the seat plate extension 21 is thereby easily detached from the clamping element 20 is and the clamping element 20 is out of engagement with the end region of the seat plate bracket 21.

At the same time, as can be seen in particular in FIG. 3.5, the last roller 18, which is arranged rotatably about the articulated shaft 27, acts on a slide 33 of the locking device 23.

The slide 7 with its joint 10 is still somewhat higher than the joint 4, but lower than in FIGS. 2.3 and 2.4.

A fully lowered position of use of the bath tub lifter R is shown in FIGS. 4.1 to 4.5. In this case, the seat plate 11 rests on the elevation 30 of the base plate and is stored there. The joints 4 and 10 engage in the area of the base plate 1.

The carriage 7 lies in an end position on a support 34, the joints 4 and 10 of the base plate 3 and carriage 7 being approximately at the same height.

Furthermore, the clamping element 20 is pivoted in the pin groove 28 by means of an engaging pin element 29 around the universal joint shaft 27, in particular via the pin groove 28 bent at the end, so that the seat plate extension 21 completely comes out of the engagement and area of the clamping element 20. As a result, the seat plate 11 is decoupled from a tilting movement shown in FIGS. 5.1 to 5.4 relative to the tilting movement of the slide 7 and the base support 5. The seat plate 11 remains parallel and independent of a tilting movement of the base support 5. The drive shaft 27 overlaps the guide element 22 of the base plate 3.

At the same time, the slide 33 of the locking device 23 is moved outwards by acting on the roller 18, which also allows the slide 7 to strike in this position in the guide groove 19, and unlocks the locking device 23.

The base support 5 and the drive device 8 can then be pivoted further against one another by the drive device 8, the drive device 8, as shown in FIG. 5.3, being pivotable about the joint 16 and the carriage 7 about the joint 4 or 10. The slide 7 and thus the base support 5 are guided along the guide element 22 via the drive shaft 27. Thus, the base support 5 is pivoted and tilted relative to the base plate 3 by an angle α, as is indicated in particular in FIG. 1.4, a movement of the seat plate 11 being decoupled therefrom by this tilting.

As can also be seen from FIG. 5.3, the clamping element 20 is out of engagement with the seat plate extension 21.

The cylinders 15.1 and 15.2 of the drive device 8 are completely retracted into one another.

In this inclined position the bath tub lifter R can be used very well and comfortably for bathing in one end position. The backrest 12, in particular, their inclination can be inclined at an angle α as required.

Another advantage of the present invention, as already mentioned above, is an extremely advantageous transport position, as shown in FIGS. 6.1 to 6.6. In the manner described above, the seat plate 11 is given away from the position of use, as shown, for example, in FIG. 2.1, about the joint 10 relative to the backrest 12, then the sliding carriage 13 with base plate 3 is moved out of the latching groove 26 of the end face 24, so that the locking element 25 of the base plate 3 is exposed. Then the base plate 3 can be pivoted relative to the sliding carriage 13 in such a way that the base carrier 5 lies approximately parallel to the base plate 1. A subsequent pushing back of the sliding carriage 13 with its joint 4 against the end face 24 of the base plate 1 enables a very short and compact transport position of the bath tub lifter R. This can then be easily transported for transport purposes.

According to FIG. 7.1, a bath tub lifter R is shown in a further preferred exemplary embodiment of the present invention, which roughly corresponds to the previous exemplary embodiment. Its base plate 1 with foot elements 2 is preferably formed in one piece, an end-side trough 36 being formed in the base plate 1 in an end region 35, as is also shown in cross section in FIG. 7.3. On the bottom side, the base plate 1 is assigned a support bed 37 which serves to receive the base plate 3. In the base plate 3, a hose handle 38 can be provided for holding the base plate 3, in particular the base support 5 with the drive device 8. At the other end of the base support 5, a handle bottle 39 can be provided for transporting the base support 5.

It is important in the present invention that base carrier 5 with drive device 8, seat element 9 is releasable and fixable with base plate 1. For this purpose, as also indicated in particular in FIG. 7.3, the base plate 3 is provided with a latching lug 40, which engages in the recess 36 of the base plate 1 with exact fit. The front lower contour of the base plate 3 lies precisely on the support bed 37 and is held there. A bolt lock 41, not shown here, engages laterally after the base plate 3 has been inserted into the base plate 1 and releasably locks the base plate 3 to the base plate 1.

Also within the scope of the present invention, for example, the trough 36 is to be designed as a latching lug 40, a corresponding trough then correspondingly being formed analogously in the base plate 3 and cooperating with a corresponding latching lug of the base plate 1 in order to close the base plate 3 relative to the base plate 1 fix or fix.

The base support 5 connects to the base plate 3, in particular in the form of double C-rails which are arranged and spaced apart from one another, as is partially shown here. As is also shown in FIG. 7.1, the base support 5 is by means of a Bolt 42 is pivotally mounted relative to the base plate 3, a flange 43 of the base support 5 having an elongated hole 44 through which a further bolt 45 of the base plate 3 engages and permits a tilting movement around the bolt 42 in the elongated hole 44. The course of the tilting movement will be referred to later.

In Figure 7.1, the seat plate 11, not visible here, is pivoted up against the carriage 7 on the backrest 12. A part of the carriage 7 is connected to the drive device 8, as is shown in particular in FIG. 2.

A further special feature of the present invention is shown in FIG. 2, a clamping piece 46 being pivotally mounted on the slide 7 about a bolt 47 and by means of a cam 48 which is guided in a cam track of the base support 5, in particular the C-rails, which is not shown here is pivotally mounted about the bolt 47. At the end, the clamping piece 46 strikes one

Stop 49 of the pivotally mounted about the joint 10

Seat plate 11 and holds it in an approximately horizontal

Position. The corresponding ones are also shown in FIG. 7.2

Rollers 18 shown, which are linearly guided in a C-rail of the base support 5, and one

Movement of the carriage 7 up and down by the drive device 8.

In the enlarged illustration according to FIG. 7.4 it can be seen that the clamping piece 45 is in engagement with the stop 49. Immediately before the seat element 9 is moved down near the base plate 1 along the base support 5, the cam 48 of the clamping piece 46 is moved out of the stop 49 of the seat element 9 via the cam path (not shown here), immediately when the seat element 9 rests on the base plate 3 and is mounted there in the manner described above, in order to ensure a subsequent pivoting of the entire base support 5 or to the rear without the seat plate 11 being caught by the pivoting movement of the base support 5, as is shown in the exemplary embodiment according to FIG. 7.6. The backrest 12 can also be tilted backwards in the manner described above. A cantilever arm 50 engages the drive device 8, which is preferably designed as a linear drive 15.1 / 15.2 and is articulatedly connected at the end to the base plate 3. The linear drive 15.1 / 15.2 is preferably designed as a spindle drive.

In the perspective illustration according to FIG. 7.7, the carriage 7 with the backrest 12 is shown, the two extension arms 50 being connected to the drive device in the manner described above. A plurality of rollers 18 are linearly attached to one another laterally on the extension arms 50 of the slide 7, these rollers being able to be moved back and forth within a C-profile of the base support 5. The hinge 10 pivotally connects the seat plate 11 to the slide 7, the stop 49 being in engagement with the clamping piece 46 in the manner described above in order to fix or adjust a horizontal position of the seat plate 11. Another peculiarity of the present invention is that the top roller 18 is an upward one

Cover 51 assigned i ^ t, which prevents, for example.

Objects, items of clothing, fingers of a human hand or the like can be clamped between rollers 18 and the C-rail or base support 5, not shown here.

Another difference between the present preferred exemplary embodiment and the one described above is shown in the following FIGS. 8.1 to 8.5. It is important in the present invention that only a lowering of the seat element 9 along the base support 5 in its approximately vertical position is possible. For this purpose, a bolt 52 connects to the base plate 3 in an articulated manner around a bolt 53, as is also shown in the perspective illustration according to FIG. 8.6. The bolt 53 engages here not shown in the base support 5 and is stored there.

The bolt 52 is also provided with a cam track 54 and cam pocket 55, in which a rocker arm 56 is mounted. At the end of the rocker arm 56, a rocker arm pin 57 engages in the cam pocket 55. At the other end, a center pin 58 is assigned to the rocker arm 56. Furthermore, the rocker arm 56 has a holding trough 59 which serves to fix the carriage 7, which is only indicated here, in particular the lowermost roller 18. A spring element 60 pulls the rocker arm 56 upwards.

In this position, the carriage 7 can be moved linearly up and down along the C-rail or the base support, with the base support 5 folding down prevented from the base plate 3, in particular is secured.

By moving the carriage 7 downward, as shown in particular in FIG. 8.2, the rocker arm pin 57 is moved out of the cam pocket 55, in which the lower roller 18 moves into the holding trough 59 and pivots it about the centering pin 58. At the same time, the clamping piece 46, as shown in FIG. 7.7, is deflected by means of the cam 48 and moved out of the stop 49, while the seat plate 11 rests on the base plate 1.

By moving the rocker arm pin 57 out of the cam pocket 55, the holding trough 59 is on the one hand

Roll 18 pivots and secures the movement of the

Carriage 7 against linear movement along the base support 5.

In the position as shown in FIG. 8.1, the base support 5 is prevented from tipping over relative to the base plate 1 by engagement of the rocker arm pin 57 in the cam pocket 55 of the bolt 52.

By shortening the drive device 8, not shown here, which engages on the base support 5 at one end and on the base plate 3 at the other end, a further tilting of the base support 5 with respect to the base plate 1 is ensured. During this tipping, the centering pin 58 of the rocker arm 56 moves along the cam track 54 of the bar 52, the bar 52 being pivoted about the pin 53 when the base support 5 is tilted. At the same time lies on the outside of the bolt 52 Rocker arm pin 57 of the rocker arm 56 and permanently holds the roller 18 of the carriage 7 by means of its holding recess 59.

Only tilting is possible in this position, as shown in FIGS. 8.3 to 8.5. The end position, in particular the tilted position of the base support 5, is shown in FIG. 8.5. Moving back accordingly takes place in the reverse manner by lengthening the drive device 8.
