Abstract
A bath lift features a lifting plate (16) connected to a hydraulic lifting hose (12) which raises it as water is supplied, and lowers it as water is drained out. Fitted to the underside of the lifting plate (16) is a manual control valve (18), from which a connection hose (20) leads to the hydraulic lifting hose. A further hose element (24) of the manual control valve (18) ends at a coupling element (22) which serves to connect a pressure-water supply hose. The manual control valve (18) also has a drain port which, in one operating position of the manual control valve, communicates with the hydraulic lifting hose (12). In the other operating position, the hydraulic lifting hose (12) is connected to the pressure-water supply, and in a neutral central position, the manual control valve shuts off the hydraulic lifting hose from the pressure-water supply and the drain port. The lifting plate (16) has a second opening (28) the same size as opening (26), and this is located at the other longitudinal side of said lifting plate (16). Furthermore, an identical arrangement of fixing holes (30) is provided on both sides of this second opening (28). In addition, the lifting plate (16) features a further fixing hole arrangement (44). The second opening (28) and the described fixing holes are, in the standard bath lift design, without function and are covered by a cushion mat. In order to provide the bath lift with a connection for a hand-held shower attachment, a shut-off spool/slider valve (48) is bolted into the second opening (28), which valve (48) features a connection fitting (50) for the shower hose and a connection (46) leading to a manifold (35) from which a further hose element (38) leads to a coupling element (40), this latter being connected not to the pressure-water supply but to coupling element (22) of the first manual control valve (18). Manifold (35) features a coupling element (36) for connection of the pressure-water supply.
The bath lift can thus be expanded by a retrofit set to include at least one further pressure-water connection, without the need to rework the lifting plate (16).
The bath lift can thus be expanded by a retrofit set to include at least one further pressure-water connection, without the need to rework the lifting plate (16).
Description
DESCRIPTION
The invention concerns a bath lift for disabled persons, with a base frame, a guide frame, a lifting plate supported and guided by this, and a hydraulic lifting hose fixed to the base plate and the lifting plate, which is connected to a manual control valve fixed on the side of said lifting plate, which valve partially passes through an opening in the lifting plate and exhibits a supply port for a connecting hose leading to a domestic water pipe.
Such a bath lift is known from DE-A-41 30 323. The disclosed bath lift has a pivoting back rest, for which a mechanical operating mechanism is provided. In the simplest case, bath lifts are connected by means of a hose to the bath tub tap fitting instead of the hose for the hand-held shower attachment. Such a bath lift is made ready for operation by operating the switching lever at the bath tub tap fitting and opening the cold water tap. The disadvantage here is that the hand-held shower attachment cannot be used. A further disadvantage lies in the fact that the lateral manual control valve is, in a large number of applications, located on the wall side of the bath tub and is therefore difficult to reach for assistants, particularly when the lifting plate is lowered and thus located below the water surface. Although "left hand" and "right hand" models can be built without difficulty, so as to fit the different bath tub installation positions, the problem still occurs-in relation to other bath tub arrangements.
The object of the invention is to provide a bath lift such that it can be easily converted from a right-side bath tub outlet to a left-side outlet, and, with replacement or retrofit sets, can be made suitable for other pressure-water-operated options.
This object is achieved with a bath lift of the type mentioned at the beginning in that the lifting plate exhibits 2I8128~
adjacent to each of its two longitudinal sides an opening, that both openings are identically contoured and are of mirrored design in relation to a longitudinal centreline along the lifting plate, that on two opposing sides of each opening there is, in each case, at least one fixing hole provided, that the manual control valve may be screwed into place below either of the two openings, and that the lifting plate exhibits additional fixing holes by means of which a manifold is secured or may be secured to the bottom of the lifting plate, said manifold exhibiting the supply connection for the interconnecting hose and a hose leading to the manual control valve, and being connected by at least one activatable connection fitting for a further pressure-water actuator/consumer.
The manifold with its connection components constitutes a retrofit set which complements the basic model where at least one further pressure-water connection is required. The retrofit set can be fitted very easily either by the manufacturer or, subsequently, by the user, providing the option of connecting a hand-held shower hose and a hydraulic actuator for a back rest adjustment system such as is known from EP-A-0622042. The connection fitting can, in the simplest case, consist of a standard commercial self-sealing quick-release coupler which opens a hose nipple on insertion.
This connection possibility does, however, require that the connected device has a shut-off valve. Hand-held shower attachments with integral shut-off valve are, therefore, just as suitable for this connection as hydraulic back rest adjustment systems which are equipped with their own manual control valve.
It is also within the scope of the invention that the manifold with self-sealing quick-disconnect coupler be replaced in a second expansion stage by a manifold with a connected second manual control valve, and also to retain the manifold with self-sealing quick-disconnect coupler and connect to this a further manifold, also equipped with a 3 2I8I28~
self-sealing quick-disconnect coupler, but which also features the connecting hose with a second manual control valve.
A constituent part of the bath lift with system expansion possibilities according to the invention is an initial cushioning mat for placement on the lifting plate, which features a lateral opening for the manual control valve. The retrofit set which contains the second manual control valve then includes a second cushion mat with two lateral openings for the two manual control valves.
The invention is explained in greater detail using the drawing which shows system expansion embodiments for bath lifts, wherein:
FIG. 1 shows a schematic side view of the bath lift, IG. 2 shows an underside view of the lifting plate of the bath lift, IG. 3 shows an underside view of the lifting plate with retrofitted expansion module, IG. 4 shows an underside view of the lifting plate with an alternative expansion module which features a second manual control valve, IG. 5 shows a basic outfit with an expansion stage containing an additional hydraulic connection which is fitted by the manufacturer, and IG. 6 shows an alternative expansion outfit to Figure 5, likewise for prefitting by the manufacturer.
A bath lift 10 consists of a base frame or base structure 13 to which a hydraulic lifting hose 12 is fitted and which supports a guide frame 14. The latter, in turn, supports and guides a lifting plate 16 with a cushion mat 17. The top of the hydraulic lifting hose 12 is fitted to the underside of the lifting plate 16. Protruding out of an opening, which is not illustrated, in the lifting plate 16 is a manual lever of a manual control valve 18, which has two operating positions and a central neutral position. The hydraulic lifting hose 12 is connected to the manual control valve 18 via a connection line 20. The manual control valve 18 additionally features a coupling element 22 as the pressure-water supply connection, and a drain line 23. In one operating position of the manual control valve 18, the hydraulic lifting hose 12 is connected via the connection hose 20 to the pressure-water supply connection, so that the hydraulic lifting hose is filled and the lifting plate 16 is raised. In the other operating position, the hydraulic lifting hose 12 is connected to the drain line 23, so that the lifting plate 16 moves downwards.
In the neutral central position, the hydraulic lifting hose 12 is shut off both from the supply connection and from the drain line.
The lifting plate 16 is provided with a back rest 19, the angle of inclination of which is adjustable. In Figure 1, a mechanical adjusting mechanism is provided at the rear of the back rest 19. As an alternative, a back rest 19 with a hydraulic actuator may be used, for example in the form of a hose element located across the back rest 19 and supported by the lifting plate 16, against which hose element an arm located towards the rear of the back rest 19 is supported and can be connected to the pressure-water supply via a delivery and drain line connected to a further manual control valve which is not illustrated.
Figure 2 then shows an underside view of the lifting plate 16 in its basic form, of which the coupling element 22 forming the supply connection is connected via a hose element 24 to the manual control valve 18, which in turn is connected via the connection hose 20 to the hydraulic lifting hose 12. The hose for the hand-held shower attachment is removed from the bath tub tap fitting, which is not illustrated, and replaced by a connection hose which is connected to the coupling element 22. The bath lift 10 is then ready for operation.
As is apparent from FIG. 2, the manual control valve 18 engages in an approximately rectangular, oblong opening 26 which is located close to a longitudinal side of the lifting plate 16. An opening 28 of the same design is located on the opposite longitudinal side of the lifting plate 16 in mirror arrangement to the longitudinal centreline of the lifting plate 16. On both sides of the openings 26, 28 are located fixing holes 30. The hole patterns of the fixing holes 30 of both openings 26, 28 are identical. The coupling element 22 is likewise bolted to the underside of the lifting plate 16 by means of bolts passing through the fixing holes 32. On the right-hand side of the lifting plate 16 shown in FIG. 2 are also located fixing holes 32, once again in a book-symmetrical arrangement relative to the holes 32 on the opposite side. The manual control valve 18 and the coupling element 22 may, therefore, be fitted either to the left or the right-hand side of the lifting plate as required. The conversion work may also be subsequently performed with ease by any layman. The cushion mat 17 merely needs to be turned around, whereupon it will also fit over the manual control valve 18 where this is located on the other side of the plate 16.
Figure 3 illustrates the first expansion stage of the basic module shown in Figure 2. This expansion stage comprises a manifold 34 with a coupling nipple 36 which constitutes the new supply connection, a hose element 38 with connection nipple 40 which, together with coupling element 22, forms a plug-in coupling assembly, and a connection fitting 42. The manifold 34 is secured by means of three bolts to the fixing holes 44 which are also already provided in the basic outfit as per FIG. 2. The connection line coming from the bath tub fitting is secured to the plug-in nipple 36 in accordance with FIG. 3. The connection fitting 42 is self-sealing and is 6 218128~
only opened on insertion of a plug-in nipple of a connection hose. With the expansion stage as per FIG. 3, the bath lift 10 can thus be operated as in the case of the basic module, the connection fitting 42 providing a further pressure-water supply option, e.g. for the connection of a shower attachment hose or of a connection hose for a hydraulic back rest adjuster.
Figure 4 shows an alternative expansion stage to that according to FIG. 3. This expansion stage likewise comprises a manifold 35, the design of which is somewhat different from that of the manifold according to FIG. 3 inasmuch as it features a central connection nipple 36 and two fixed outlet lines 38, 46. Line 38 is, in turn, connected via a connection nipple to the coupler 22, and the hose line 46 ends in a second manual control valve 48 which is bolted in the free opening 28 of the lifting plate 16. This second manual control valve features at the outlet end a connection fitting 50. The second manual control valve 48 is a shut-off valve.
The hose of a hand-held shower attachment may thus be connected to connection fitting 50. The hand-held shower attachment is activated by operation of the second manual control valve 48.
FIG. 5 shows a variant which corresponds to that according to FIG. 3, but without the coupling arrangement with coupling components 22, 40. This version is employed if a lift is ordered to include the first expansion stage. The manifold 34 is the same as in the embodiment according to FIG. 3.
However, it is permanently connected to the first manual control valve 18 by hose 39. Hose element 24 is therefore omitted.
FIG. 6 shows a connection arrangement corresponding to that of FIG. 4 for the case where the bath lift is ordered from the manufacturer with an alternative expansion stage. Here, too, the hose coupling arrangement 22, 40 is omitted.

An embodiment not illustrated features a manifold which constitutes a combination of the two illustrated manifolds 34, 35, in which namely manifold 34 exhibits connection hoses 38/39 and 46 on the two sides respectively, so that the bath lift 10 possesses two connection fittings 42, 50 so as to enable, for example, a shower attachment hose and a connection hose for the hydraulic angle adjustment system of the back rest to be connected.
The second manual control valve 48 according to Figures 4 and 6 is - because it is designed as a pure shut-off valve -suitable for the connection of a hand-held shower attachment.
If, on the other hand, the hydraulic actuator for the back rest adjustment system is to be connected, a second manual control valve in the form of a three-way directional valve is required corresponding to that which constitutes the first manual control valve 18.
The invention concerns a bath lift for disabled persons, with a base frame, a guide frame, a lifting plate supported and guided by this, and a hydraulic lifting hose fixed to the base plate and the lifting plate, which is connected to a manual control valve fixed on the side of said lifting plate, which valve partially passes through an opening in the lifting plate and exhibits a supply port for a connecting hose leading to a domestic water pipe.

The retrofit set which contains the second manual control valve then includes a second cushion mat with two lateral openings for the two manual control valves.
The invention is explained in greater detail using the drawing which shows system expansion embodiments for bath lifts, wherein:
FIG. 1 shows a schematic side view of the bath lift, IG. 2 shows an underside view of the lifting plate of the bath lift, IG. 3 shows an underside view of the lifting plate with retrofitted expansion module, IG. 4 shows an underside view of the lifting plate with an alternative expansion module which features a second manual control valve, IG. 5 shows a basic outfit with an expansion stage containing an additional hydraulic connection which is fitted by the manufacturer, and IG. 6 shows an alternative expansion outfit to Figure 5, likewise for prefitting by the manufacturer.
A bath lift 10 consists of a base frame or base structure 13 to which a hydraulic lifting hose 12 is fitted and which supports a guide frame 14. The latter, in turn, supports and guides a lifting plate 16 with a cushion mat 17. The top of the hydraulic lifting hose 12 is fitted to the underside of the lifting plate 16. Protruding out of an opening, which is not illustrated, in the lifting plate 16 is a manual lever of a manual control valve 18, which has two operating positions and a central neutral position. The hydraulic lifting hose 12 is connected to the manual control valve 18 via a connection line 20. The manual control valve 18 additionally features a coupling element 22 as the pressure-water supply connection, and a drain line 23. In one operating position of the manual control valve 18, the hydraulic lifting hose 12 is connected via the connection hose 20 to the pressure-water supply connection, so that the hydraulic lifting hose is filled and the lifting plate 16 is raised. In the other operating position, the hydraulic lifting hose 12 is connected to the drain line 23, so that the lifting plate 16 moves downwards.
In the neutral central position, the hydraulic lifting hose 12 is shut off both from the supply connection and from the drain line.
The lifting plate 16 is provided with a back rest 19, the angle of inclination of which is adjustable. In Figure 1, a mechanical adjusting mechanism is provided at the rear of the back rest 19. As an alternative, a back rest 19 with a hydraulic actuator may be used, for example in the form of a hose element located across the back rest 19 and supported by the lifting plate 16, against which hose element an arm located towards the rear of the back rest 19 is supported and can be connected to the pressure-water supply via a delivery and drain line connected to a further manual control valve which is not illustrated.
Figure 2 then shows an underside view of the lifting plate 16 in its basic form, of which the coupling element 22 forming the supply connection is connected via a hose element 24 to the manual control valve 18, which in turn is connected via the connection hose 20 to the hydraulic lifting hose 12. The hose for the hand-held shower attachment is removed from the bath tub tap fitting, which is not illustrated, and replaced by a connection hose which is connected to the coupling element 22. The bath lift 10 is then ready for operation.
As is apparent from FIG. 2, the manual control valve 18 engages in an approximately rectangular, oblong opening 26 which is located close to a longitudinal side of the lifting plate 16. An opening 28 of the same design is located on the opposite longitudinal side of the lifting plate 16 in mirror arrangement to the longitudinal centreline of the lifting plate 16. On both sides of the openings 26, 28 are located fixing holes 30. The hole patterns of the fixing holes 30 of both openings 26, 28 are identical. The coupling element 22 is likewise bolted to the underside of the lifting plate 16 by means of bolts passing through the fixing holes 32. On the right-hand side of the lifting plate 16 shown in FIG. 2 are also located fixing holes 32, once again in a book-symmetrical arrangement relative to the holes 32 on the opposite side. The manual control valve 18 and the coupling element 22 may, therefore, be fitted either to the left or the right-hand side of the lifting plate as required. The conversion work may also be subsequently performed with ease by any layman. The cushion mat 17 merely needs to be turned around, whereupon it will also fit over the manual control valve 18 where this is located on the other side of the plate 16.
Figure 3 illustrates the first expansion stage of the basic module shown in Figure 2. This expansion stage comprises a manifold 34 with a coupling nipple 36 which constitutes the new supply connection, a hose element 38 with connection nipple 40 which, together with coupling element 22, forms a plug-in coupling assembly, and a connection fitting 42. The manifold 34 is secured by means of three bolts to the fixing holes 44 which are also already provided in the basic outfit as per FIG. 2. The connection line coming from the bath tub fitting is secured to the plug-in nipple 36 in accordance with FIG. 3. The connection fitting 42 is self-sealing and is 6 218128~
only opened on insertion of a plug-in nipple of a connection hose. With the expansion stage as per FIG. 3, the bath lift 10 can thus be operated as in the case of the basic module, the connection fitting 42 providing a further pressure-water supply option, e.g. for the connection of a shower attachment hose or of a connection hose for a hydraulic back rest adjuster.
Figure 4 shows an alternative expansion stage to that according to FIG. 3. This expansion stage likewise comprises a manifold 35, the design of which is somewhat different from that of the manifold according to FIG. 3 inasmuch as it features a central connection nipple 36 and two fixed outlet lines 38, 46. Line 38 is, in turn, connected via a connection nipple to the coupler 22, and the hose line 46 ends in a second manual control valve 48 which is bolted in the free opening 28 of the lifting plate 16. This second manual control valve features at the outlet end a connection fitting 50. The second manual control valve 48 is a shut-off valve.
The hose of a hand-held shower attachment may thus be connected to connection fitting 50. The hand-held shower attachment is activated by operation of the second manual control valve 48.
FIG. 5 shows a variant which corresponds to that according to FIG. 3, but without the coupling arrangement with coupling components 22, 40. This version is employed if a lift is ordered to include the first expansion stage. The manifold 34 is the same as in the embodiment according to FIG. 3.
However, it is permanently connected to the first manual control valve 18 by hose 39. Hose element 24 is therefore omitted.
FIG. 6 shows a connection arrangement corresponding to that of FIG. 4 for the case where the bath lift is ordered from the manufacturer with an alternative expansion stage. Here, too, the hose coupling arrangement 22, 40 is omitted.

An embodiment not illustrated features a manifold which constitutes a combination of the two illustrated manifolds 34, 35, in which namely manifold 34 exhibits connection hoses 38/39 and 46 on the two sides respectively, so that the bath lift 10 possesses two connection fittings 42, 50 so as to enable, for example, a shower attachment hose and a connection hose for the hydraulic angle adjustment system of the back rest to be connected.
The second manual control valve 48 according to Figures 4 and 6 is - because it is designed as a pure shut-off valve -suitable for the connection of a hand-held shower attachment.
If, on the other hand, the hydraulic actuator for the back rest adjustment system is to be connected, a second manual control valve in the form of a three-way directional valve is required corresponding to that which constitutes the first manual control valve 18.
