Description

BACKGROUND OF THE INVENTION

The invention relates to a tub arrangement comprising leg sections coupled together by hinges for bending the leg sections around the hinges, the leg sections being connected to wheels and a two-part tub, to which one of the leg sections is fixed and which comprises a separate seat section and correspondingly a separate foot section, the tub being turnable around a horizontal axis so that a person taking a bath can either lie or sit in the tub.

The prior art teaches different manners of using a tub for bathing. Finnish Patent 97,272 discloses a tub arrangement with a two-part tub. The two-part tub consists of a seat section and a foot section and it is mounted on a leg section provided with hinges and wheels. The leg section can be bent around the hinges, so that the tub can be positioned either in a horizontal position or in a seating position. A drawback of such an arrangement is that when the tub is being changed from one position to another, the tub arrangement moves on the push surface where it is located due to the wheels of the leg section, thus requiring at least two people to change the position of the tub. Furthermore, if the tub is at least partly filled with liquid and there is a person bathing in the tub, changing the position of the tub requires strenuous efforts.

BRIEF DESCRIPTION OF THE INVENTION

An objective of the present invention is to provide a tub arrangement with none of the aforementioned drawbacks.

A tub arrangement according to the invention is characterized in that the arrangement comprises a power element connected to the leg sections for adjusting the distance between a first connecting point and a second connecting point.

According to a basic idea of the invention, one of the wheel pairs arranged in the leg section of the tub arrangement is locked into a non-rotating position, so that when the distance between the connecting points is adjusted by means of the power element, the position of the tub can be changed in a small space.

An advantage of the tub arrangement according to the invention is that the tub can be easily changed from one position to another, and the tub remains substantially in place on the floor. Another advantage of the tub arrangement according to the invention is that when the tub is installed in the sitting position, it requires only a little space and it is easy to step into the tub for a bath. This is particularly useful when disabled or elderly people utilize the tub arrangement.

A tub arrangement according to one embodiment of the invention is further characterized in that one sections of the leg/supporting sections comprise a legs positioned against the floor, wherein a supporting arrangement to the wall, as closet wall, is working as the other leg sections, which arrangement comprising a rail fitted on the wall on which rail a roll or like fixed to the tub moves for turning the tub around its horizontal axis.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a schematic side view of a tub arrangement according to the invention in a horizontal position, the tub arrangement comprising a tub 1 with a seat section 1a and a foot section 1b. Between the seat section 1a and the foot section 1b, the bottom of the tub rises to such an extent that in the horizontal position of the tub the sections constitute clearly separate parts of the tub, yet if desired, a person bathing in the tub can covered by water or some other liquid up to his/her neck. The bottom of the seat section 1a is provided with a drainage duct for the seat section, which is not shown in the figures, and correspondingly, the bottom of the foot section 1b is provided with a drainage duct for the foot section, not shown in the figures, either. Liquid can be discharged from the tub 1 via these ducts. The bottom and the sides of the tub are also provided with feed ducts not shown in FIG. 1 for feeding liquid, such as water, or gas, such as steam, at a high pressure either in a continuous or pulse-like flow. The placement and number of the feed ducts in each section 1a and 1b of the tub can vary, i.e. the liquid or gas can be fed into the tub 1 via the feed ducts of either the seat section 1a or the foot section 1b, or if desired, via the feed ducts of both sections.

The tub arrangement comprises a tub 1 and a leg section, which consists of a leg section 2a on the side of the seat section 1a, a leg section 2b on the side of the foot section 1b, hinges 3a and 3b for coupling the leg sections 2a and 2b together, wheels 4a of the leg section 2a of the seat section 1a, and wheels 4b of the leg section 2b of the foot section 1b. The tub 1 is firmly fastened to leg section 2b by fastening means 10a and 10b, so that the tub 1 is substantially immovable with respect to leg section 2b irrespective of whether the tub 1 is in the sitting or the horizontal position. The pairs of wheels 4a and 4b are arranged in the leg sections 2a and 2b such that in the sitting position the centre of gravity of the tub arrangement with respect to the push surface 9 is located in such a manner that the tub will not keel over irrespective of whether it is empty or filled with liquid. The leg section 2a on the side of the seat section 1a is connected by a power element 6 to the leg section 2b on the side of the foot section 1b at connecting points 7 and 8. The power element 6 can be for example a piston-type cylinder, where the length of stroke is controlled for example hydraulically or pneumatically. The essential fact is that the power element 6 controls the distance between the first connecting point 7 and the second connecting point 8. The wheels 4a and 4b are provided with locking mechanisms 5a and 5b for locking the wheels 4a, 4b into a non-rotating position. The wheels 4b, the locking mechanisms 5b, the hinge 3b and the fastening means 10b will be shown below in FIGS. 3a, 3b and 3c. The locking mechanisms 5a and 5b of the wheels 4a and 4b for locking the wheels into a non-rotating position either mechanically, electrically or pneumatically are known per se to a person skilled in the art, wherefore the structure and operation thereof will not be described in more detail herein. The leg sections 2a and 2b can be bent around the hinges 3a and 3b, so that the tub 1 can be placed either in the horizontal position shown in FIG. 1 or in the sitting position shown in FIG. 2.

FIG. 2 shows schematically the tub arrangement according to FIG. 1, where the tub 1 has been turned into a sitting position. In this position, it is easy to step into the tub 1, whereafter the tub can be turned into a suitable position for a bath. The tub 1 can be changed from one position to another in two different manners. Firstly, the horizontal position shown in FIG. 1 can be changed into the sitting position shown in FIG. 2 by locking the wheels 4a as described above, and by shortening the distance between the connecting points 7 and 8 by the power element 6. Furthermore, the sitting position shown in FIG. 2 can be changed back into the horizontal position shown in FIG. 1 by locking the wheels 4a as described above and by lengthening the distance between the connecting points 7 and 8 by the power element 6. In the second manner, the horizontal position shown in FIG. 1 is converted into the sitting position shown in FIG. 2 by locking the wheels 4b as described above and by shortening the distance between the connecting points 7 and 8 by the power element 6. Furthermore, in the second manner the sitting position shown in FIG. 2 is reconverted into the horizontal position shown in FIG. 1 by locking the wheels 4b as described above and by lengthening the distance between the connecting points 7 and 8 by the power element 6.

FIGS. 3 a, 3 b and 3c are schematic bottom views of different embodiments of the tub arrangement according to the invention.

In the FIG. 4 there is a tub arrangement, as one leg parts 2b of which are against floor placed legs which are equipped with wheels 4d, 4e. The leg part 2b has been firmly fixed to the tub by means of a part 10a. The turning motions for the tub are done by means of power element 6, one fixing point 8 of which locating in a leg 2b and the other fixing point 7 on a wall of the closet 11. There on the closet wall has been arranged a curved rail 12 and a roll 13 rolling along rails 12 has been fixed to the tub, wherein the power element 6 pulls the fixing points 7 and 8 nearer to each other, the tub turns into vertical position and moves into the closet 11, as described in FIG. 5. When the power element is lengthening the distance between the fixing points 7,8, the tub is turning into horizontal position, as it is in FIG. 4. The leg 2b has been equipped with two successive wheels 4d, 4e, wherein the lower end of the tub is easily moving in whole moving range when it is lifted up.

The invention is described in the above specification and in the drawings only by way of an example, and it is not restricted thereto in any way. Therefore, the structures of the leg sections 2a and 2b can vary, as long as the tub 1 can be turned into the required positions. The number of the wheels 4a and 4b is not restricted to the aforementioned four wheels, either, but the number thereof must be substantially sufficient to keep the tub arrangement firmly upright on the push surface 9. Moreover, the leg sections 2a and 2b can be anchored for example to the push surface 9 or to a wall surface by different anchoring means, such as hooks, or the push surface 9, along which the tub arrangement according to the invention is being moved, can be provided with protrusions or recesses that prevent the wheels 4a and 4b from rotating.
