Description

[0001] BATHTUB AND / OR SHOWER TRAY

[0002] The present invention relates to a bathtub and / or shower tray with a base part and a wall or side element which completely surrounds a circumference of the base part and is arranged substantially perpendicular to the base part, wherein the wall or side element is formed in several parts from substantially annular elements which can be fixed tightly to one another, wherein all of the substantially annular elements surrounding the base part are displaceable relative to one another in the direction of a vertical extension of the bathtub and / or shower tray and relative to the base part, wherein at least one lifting and lowering mechanism is provided which is hinged to the annular element which is displaceable the furthest relative to the base part, wherein the base part is surrounded by a drain channel having drain fittings and the annular elements are arranged so as to be retractable into the drain channel.

[0003] Bathtubs and / or shower trays can be found in a wide variety of sizes, designs, and depths in almost every home or apartment. However, in modern homes in particular, the desire of residents to have a bathroom that includes both a bathtub and a shower tray is often not fulfilled due to limited space. Both elements, the bathtub and the shower tray, have their advantages and disadvantages. For example, a shower tray is easy for older people and / or people with limited mobility to get into. On the other hand, full-body cleaning, especially for people with limited mobility or children, is more comfortable and easier in a bathtub. However, the high edge of the bathtub makes getting in and out without aids almost impossible, especially for people with limited mobility.

[0004] To enable these people to step in and out of such a deep bathtub, bathtubs have already been provided with access openings or doors into which the user can easily step in and out. However, a disadvantage of such bathtubs is still the fact that a showering element as deep as a conventional bathtub is not required. Even if a flat or nearly flat surface can be provided for showering, technical problems remain with regard to water drainage, the ability to clean the entire bathtub and / or shower tray, and so on.

[0005] EP 3378366 A discloses a bathtub and / or shower tray which can form both a bathtub with sufficient depth and a shower tray flush with the surrounding bathroom floor. A disadvantage of this type of bathtub and / or shower tray is that either a base section is connected to drain fittings, so that before the individual interlocking elements forming the bathtub are lowered, the bathtub must be completely emptied to prevent water from overflowing. On the other hand, it is also known that when the elements forming the bathtub are sunk, they are lowered into a drainage channel in which drains are formed or at least one drain is formed through which the water is intended to flow away.The disadvantage of this type of design is that the profiles of the tub that are lowered into the drainage channel almost completely fill the drainage channel, which massively hinders the rapid drainage of the water.

[0006] CH-PS 52381 discloses a further embodiment of a collapsible bathtub, which consists of a tub-shaped base element and telescopically movable wall elements, which are held in place by means of support elements that can be clamped under the upper edge in order to prevent the individual elements from accidentally sliding into one another.

[0007] The present invention therefore aims at such a bathtub and / or shower tray which is designed such that its wall or side element height can be completely lowered into the floor and forms a flat surface which enables quick and reliable emptying of the bathtub or complete drainage of water during a shower and which is also easy to clean and requires little maintenance.

[0008] In order to meet both requirements in one and the same bathtub and / or shower tray, namely to be able to provide a bathtub which is easy to get in and out of and, on the other hand, to provide a shower tray which forms a level surface when showering and, on the other hand, a bathtub which has a corresponding installation depth to be able to fill in sufficient water to be able to take a full bath, it is therefore necessary to provide a bathtub and / or shower tray which can be adjusted in such a way that it forms a level surface with the surrounding bathroom floor and, moreover, it is guaranteed that either water coming from the bathtub or water added when showering can be safely and reliably drained via the water in or out of the bathtub.To achieve this object, the bathtub and / or shower tray is essentially characterized in that the drainage channel is formed from two drainage channel parts which merge into one another, a lower and an upper drainage channel part, that a plurality of support elements designed to support the essentially annular elements are provided in the lower drainage channel part, and that at least one drain connected to at least one water drainage pipe is formed in the lower drainage channel part.Because the drain channel is formed from two merging drain channel sections, a lower and an upper drain channel section, it is possible to completely submerge the essentially annular elements into one, namely the upper drain channel section. When the essentially annular elements are lowered, a shower tray is formed, which forms a completely flat surface that is flush with, for example, a bathroom floor. By also providing a second, particularly lower, drain channel section, the water that is emptied from a filled bathtub or that hits the formed flat surface while showering is drained downwards through the upper drain channel and guided via the lower drain channel into, for example, a drain.In this way, it can be ensured that water does not accidentally run into the bathroom or remain standing in a drainage channel, as was the case with prior art bathtubs, which could be lowered to form a flat surface, but the channel into which the elements forming the bathtub were sunk could not be completely emptied due to tub elements obstructing the free drainage of water. The problems caused by stagnant water, hair, soap residue, and the like, as well as problems caused by accidental water leakage into the bathroom with the well-known adverse consequences of a slippery floor, bathroom furniture damaged by moisture, or the like, can be reliably avoided with a design according to the present invention.

[0009] The term "merging drainage channel parts" means that the two drainage channel parts are separated, for example, by a step, a bevel, a cross-sectional taper or the like, but form a common water absorption volume, in which the at least partially open upper side of the lower water absorption volume simultaneously forms a virtual continuation of a bottom surface of the upper water absorption volume.

[0010] Further security, as provided by the invention, is provided by the formation of a drain connected to water drainage pipes in the lower drain channel section. This ensures that the drain is located in the lowest part of the bathtub or shower tray, reliably preventing water from stagnating in any part of the device.

[0011] If the bathtub and / or shower tray, as corresponds to a further development of the invention, is designed such that the essentially annular elements are designed as interlocking, essentially L-shaped individual profiles and that sealing elements, in particular annular seals, are provided between the interlocking legs of the individual profiles, it is possible to form the tub from detachably connectable individual profiles, which is tight in its upright state by inserting sealing elements between the individual profiles and to further ensure that, in the lowered state of the essentially annular elements, water can pass through between the individual annular elements.Sealing is achieved by the weight of the individual elements, which are hooked into each other; a connection of the essentially ring-shaped profiles to each other, for example by means of a flexible silicone element, can be omitted.

[0012] To ensure that when lowering the plurality of substantially annular elements, water does not suddenly leak between all of the substantially annular elements connected only by the seals and an excessive amount of water flows into the drainage channel, the substantially annular elements are lowered in such a way that water first escapes between the base element and the first element, then between the first and second elements, etc. This is achieved because, due to the water pressure, the lowest element is the first to disengage from the base element and subsequently reaches its desired level or lowered state first.In this way, it is possible to prevent excessive amounts of water from escaping at the same time and finally, as corresponds to a further development of the invention, the device can be developed in such a way that a plurality of sensors are provided which monitor the water level in the drainage channel, the speed of lowering of the individual ring-shaped elements and the like and, in the event of too rapid lowering or too high a water level in the drainage channel, immediately issue a corresponding signal and, in the worst case, reverse the movement in order to prevent, for example, a bathroom from flooding.

[0013] In practice, the essentially I-shaped elements usually correspond to an L pivoted by 180°, or a kind of hook, so that the downward-facing edge of each element is essentially straight.

[0014] In order to prevent the individual, essentially annular elements from bulging or being pre-shaped by the water pressure prevailing inside the bathtub, particularly in the case of a bathtub completely filled with water, i.e. in a state in which essentially all of the essentially L-shaped elements are at their maximum vertical extent or are hooked into one another, the invention is further developed such that stiffening elements are provided on an outer circumference of the essentially annular elements, at least partially encompassing them. By providing stiffening elements on an outer circumference of the essentially annular elements, at least partially encompassing them, it is possible to reliably prevent the essentially annular elements from bulging outwards due to the water pressure prevailing inside the bathtub and / or shower tray.By stiffening elements that at least partially surround an outer circumference, we mean that the stiffening elements are arranged on the outside of the essentially annular elements, whether they are screwed to them, glued to them, formed integrally with them, the material is reinforced, the stiffening element is incorporated into the material thickness, or similar. And that partially encompassing, particularly in bathtub designs that are not circular but, for example, have an elliptical shape or the like, means that the long sides or extended sides are formed with stiffening elements. The parts of the essentially circular elements that have a relatively large curvature, such as headboards or the like, do not require any stiffening elements, since they are not susceptible to bulging or are only susceptible to this to a very limited extent.

[0015] In order to provide a safe standing surface and, in particular, to prevent any risk of accidents, even when the individual, essentially ring-shaped elements are in the lowered state, the invention is further developed such that, when the ring-shaped elements are in the lowered state, the upper drain channel section is completely covered by the upper legs of the essentially L-shaped individual profiles. Because the upper drain channel section is completely covered by the upper legs of the essentially L-shaped individual profiles, not only is a flat surface provided, but the narrow gaps that are inevitably formed between the individual, essentially L-shaped individual profiles allow the water to drain safely and reliably into the lower drain channel section, preventing water from leaking out of the area of ​​the flat shower tray.The gaps form primarily because a bathtub wall is not, in principle, completely vertical, but rather has an inclined shape, tapering toward a floor section. When lowered, depending on the degree of inclination, a small gap inevitably forms between the respective upper legs of two adjacent, essentially L-shaped individual profiles. According to the present invention, this small gap is used as part of a water drain when the essentially annular elements are lowered.

[0016] By designing the bathtub and / or shower tray in such a way that the support elements are designed as support webs or support studs, as is the case with a further development of the invention, it is ensured that when the bathtub and / or shower tray is submerged, the essentially annular elements rest on the support webs or support studs and that the free drainage of water into the lower drain channel section cannot be obstructed. To prevent water from accumulating on the support studs or support webs, the design can be such that between more than two support webs or a row of support studs, a drain is provided which is connected to a central drain arranged beneath the bathtub or shower tray, so that water can flow into the central drain from a variety of directions.Such a design not only ensures that even large quantities of water can drain away quickly and reliably, but also reliably prevents the drainage channel from overflowing.

[0017] By designing the support webs as webs that bridge the lower drainage channel part and are releasably secured therein, as is a further development of the invention, a further simplification of the device can be provided, in which the provision of multiple drainage openings can be avoided, but rather the entire lower drainage channel part is available to receive water, which can flow freely in this lower drainage channel part, thus ensuring that the water drains away quickly at the provided drainage opening(s). Furthermore, by designing the support webs as releasably secured webs, they can be easily removed, for example, for maintenance or cleaning purposes, which also ensures a hygienic design, as it is guaranteed that no residues such as hair or the like remain on the webs.can be stored or they can be cleaned quickly and easily.

[0018] For further safety of the bathtub and / or shower tray, the invention is designed such that the support webs have a number of recesses or notches corresponding to the number of annular elements. Because the support webs have a number of recesses or notches corresponding to the number of annular elements, it is ensured that, when the bathtub and / or shower tray is lowered, each annular, essentially L-shaped element is arranged in one of the notches or recesses, thereby reliably preventing the individual, essentially annular elements from shifting against one another and thus preventing larger gaps from inadvertently forming in the flat floor surface, which only has narrow drainage gaps.In the same way, as corresponds to a further development of the invention, the design can be such that the support studs are arranged at a distance from one another on a bottom surface of the lower drainage channel and that a plurality of groups of support studs are provided, wherein a group of support studs each extends in the radial direction of the lower drainage channel and is arranged next to one another in a number of support studs corresponding to the number of annular elements. By arranging a plurality of support studs at a distance from one another on a bottom surface of the lower drainage channel, it is possible to provide support studs for the essentially annular elements and at the same time ensure that the water drain inside the lower drainage channel is not blocked and the water can flow through the free space between the individual studs.By simultaneously arranging a plurality of groups of support studs extending in the radial direction of the lower drain channel and these groups having a corresponding number of support studs next to one another for the number of ring-shaped elements, a plurality of support points is provided for each of the ring-shaped elements and thus ensuring that even when there is a load on the upper side of the essentially ring-shaped elements, e.g. when the bathtub and / or shower tray is in the lowered state and is being used as a shower tray, there is no unintentional tilting or bending of the individual elements and thus a smooth and level floor without any level differences can be provided.

[0019] As corresponds to a further development of the bathtub and / or shower tray, the design is such that the base part is formed from at least one substantially hollow box-shaped element and a substantially plate-shaped element detachably attached thereto, the overall weight of the bathtub and / or shower tray is reduced and a fixed or rigid base is provided which does not bend under weight, be it the weight of the water or the weight of one or more users, and which also has an aesthetically pleasing appearance.

[0020] By arranging control or regulating elements, in particular the elements for controlling the raising and / or lowering of the essentially ring-shaped elements, inside the essentially hollow box-shaped element, as corresponds to a further development of the invention, it is unnecessary to provide a separate control box for controlling the bathtub and / or shower tray. Of course, the essentially hollow box-shaped element can not only accommodate the control or regulating device for adjusting the height of the shower tray and / or bathtub, but also the control of the amount and / or temperature of the required water, a wide variety of sensor elements, and the like, be it to be able to operate the bathtub and / or shower tray with a remote control, with a mobile phone, or in any other way, be it to switch between a water supply for a bath or one for a shower, and the like.Of course, traditional operation is also possible, for example using push buttons to raise or lower the tub or traditional taps. The hollow, box-shaped element can also contain all other elements for the water supply, mixer taps, or the like. Furthermore, with such a design, the fact that the essentially box-shaped element is covered with a detachably attached, essentially plate-shaped element ensures that no moisture can penetrate into the interior of the essentially box-shaped element and that no locking elements or other fastening elements are visible on a surface facing the interior of the bathtub and / or shower tray. Finally, such a design enables easy cleaning of the entire base section of the bathtub or shower tray.

[0021] As a further development of the invention, the device is designed such that the base part has a plurality of nozzles, in particular air and / or water supply nozzles, it is possible to use the bathtub and / or shower tray directly as a whirlpool or massage tub without having to make changes to the essentially annular profiles or drainage channels.

[0022] If, as is the case with a further development of the invention, the lifting and lowering mechanism is formed by at least two electrically, hydraulically, or pneumatically actuated lifting cylinders, in particular those actuated by remote control, one-sided lifting of the bathtub is reliably prevented. The design can be such, as is known per se, that the respective lifting and / or lowering mechanism engages the uppermost, substantially annular element and ensures lowering or raising. It goes without saying that the uppermost, substantially annular element, as well as the drainage channel part, requires stiffening in the area of ​​the lifting and lowering mechanism in order to reliably prevent the elements, which are usually made of plastic, from tearing out.Considering the fact that such stiffening elements can either extend over the entire circumference of the uppermost substantially annular element and the drainage channel part or can be formed only locally and can be selected from any materials or possibilities, it is unnecessary to discuss these stiffening elements in more detail.

[0023] The entire bathtub and / or shower tray can be operated either by remote control or traditionally using buttons and an electric control system. Naturally, all kinds of sensor control, control via mobile phone or remote control, pre-programmable fill and drain times, and the like are possible. Since such control and regulation elements, or even programmable elements, are familiar to experts, there is no need to go into them in more detail.

[0024] The invention will be explained in more detail below with reference to exemplary embodiments shown in the drawings.

[0025] Fig. 1 is a view of the bathtub and / or shower tray according to the invention,

[0026] Fig. 2 is a side view of the bathtub and / or shower tray of Fig. 1,

[0027] Fig. 3 a view from above of the bathtub and / or shower tray in lowered position, and.

[0028] Fig. 4 is an exploded view of the individual elements forming a variant of the bathtub and / or shower tray.

[0029] In Fig. 1, the general reference numeral 1 designates a bathtub and / or shower tray, which in the present case is formed from five essentially annular elements 2 that can be pushed into or apart from one another. In the illustration in Fig. 1, the essentially annular elements 2 are shown in the maximally pushed-apart state, so that a bathtub 1 with a conventional depth of between 35 cm and 50 cm was formed. The height of the bathtub or shower tray 1 is adjusted by means of a lifting or lowering mechanism 3 acting on the uppermost annular element 2, wherein the uppermost annular element 2 is reinforced for the action of the lifting and lowering mechanism 3, and a reinforcing element 5 for the lifting or lowering mechanism 3 is provided in the upper drain channel 4. The bathtub or shower tray 1 according to Fig.1 is designed such that the lowermost, substantially annular element 2 engages in a floor part 6, wherein according to the invention the floor part 6 is aligned and level with, for example, a bathroom floor (not shown), in order to achieve a surface flush with the bathroom floor when the substantially annular elements 2 are pushed together.

[0030] In order to form a single plane with the base part 6 of the bathtub and / or shower tray 1 when the essentially annular elements 2 are pushed together, a water drainage channel 4 must be provided beneath the bathtub and / or shower tray 1, the depth of which corresponds at least to the height of the individual essentially annular elements 2. According to the invention, the water drainage channel 4 is now designed such that it is formed from two interconnected drainage channel parts 4 and 7, a lower 7 and an upper 4 drainage channel part. In the lower drainage channel part 7, a plurality of support elements 8 are provided, on which the individual essentially annular elements 2 rest when the bathtub and / or shower tray 1 is in the lowered state.In the embodiment shown, the support elements 8 are designed as webs that bridge the lower drain channel part 7 and are inserted into recesses 9 of the lower drain channel part 7. The support elements 8 can also be designed with knobs or as webs that are screwed in or tightly inserted into corresponding recesses or the like. The support elements 8 also have a number of ribs 10 corresponding to the number of essentially annular elements 2, in order to enable the individual elements 2 to rest on a non-displaced surface when the bathtub and / or shower tray 1 is lowered.

[0031] Any type of lifting cylinder can be used as the lifting or lowering mechanism 3, such as hydraulically, pneumatically, or electrically operated lifting cylinders. In this context, it should be noted that the weight that must be supported by such lifting and lowering mechanisms 3 is relatively low, since, for example, in plastic bathtubs, the essentially ring-shaped elements 2 are very light, and thus the forces acting vertically on the bathtub or shower tray 1 are relatively low.

[0032] In Fig. 1, the cup 11 with the drainage channels 4, 7 is further provided in the area around the upper drainage channel part 4 with feet, in particular height-adjustable feet 12, in order to be able to provide a 100% horizontal design of the bathtub and / or shower tray 1.

[0033] Finally, as is also not shown in the present embodiment, the bathtub or shower tray 1 can be covered with a covering element on its outside to increase its aesthetics.

[0034] In Fig. 2, the reference numerals from Fig. 1 have essentially been retained, with the bathtub and / or shower tray 1 being shown as a side view, additionally showing the configuration located beneath the tray 11. In addition to the elements already shown in Fig. 1, Fig. 2 also schematically shows a drive unit 13 for the raising and lowering mechanism 3, as well as a drain 14 so that the water flowing into the lower water drainage channel 7 can drain away safely.

[0035] Fig. 3 shows the bathtub and / or shower tray 1 in its folded or nested state of the annular elements 2, wherein the base part 6 is arranged on a level with the substantially annular elements 2 sunk into the drainage channel 4, and the respective upper legs 15 of the substantially L-shaped profiles of the substantially annular elements 2 are designed such that the drainage channel 4, 7 is completely covered by these upper legs 15, so that the risk of accidents, particularly when stepping onto the base element 6 of the bathtub and / or shower tray 1, is minimized as much as possible. It goes without saying that such a design of the bathtub and / or shower tray 1 can be used directly as a shower, in that wastewater from showering flows between the substantially annular elements 2 into the drainage channel 4, 7 and is transported away from there via the drain 14.

[0036] Fig. 4 shows an exploded view of the individual elements forming a variant of the bathtub and / or shower tray 1. In this exploded view, in addition to the elements essential for the design of the bathtub and / or shower tray 1, this exploded view also shows, for example, a height adjustment for the feet 12, seals for the reinforcing elements 5 of the raising and lowering mechanisms 3, fastening elements, and the like, which, however, are not essential for the functioning of the bathtub and / or shower tray 1 and are therefore not described separately.

[0037] In detail, it can be seen from Fig. 4 that each essentially annular element 2 is formed with an upper edge 15, into which upper edge 15 a seal 16 is inserted. However, the essentially annular elements 2 can also be essentially Z-shaped, wherein a lower edge not shown in Fig. 4 would also be formed. This essentially Z-shaped design of the essentially annular elements 2 is, on the one hand, more difficult to clean, since water always remains in the lower channel of the Z, and, on the other hand, the free drainage of water is somewhat more difficult.Due to the essentially L-shaped or Z-shaped design of the essentially annular elements 2, two essentially annular elements 2 that follow one another in the vertical direction are connected only by the inserted seal 16, so that during lowering the elements 2 are disengaged and water passes between the essentially annular elements 2. In order to prevent bulging of the essentially annular elements 2 due to the water pressure prevailing in a filled bathtub 1, the respective long sides of the bathtub and / or shower tray 1 are further provided with stiffening elements 20. The stiffening elements 20 are preferably metal stiffeners incorporated into the material thickness of each essentially annular element 2. Finally, the elements 20 could also be designed as material reinforcements.

[0038] Furthermore, it is clearly evident from Fig. 4 that the uppermost annular element 2 has a significantly wider edge 15 of the substantially L-shaped element than the other substantially annular elements 2. Stiffening elements 5 are provided beneath this wide edge 15, through which, as well as through the edge 15, the lifting and lowering mechanisms 3 pass to enable the bathtub and / or shower tray 1 to be raised and lowered.

[0039] Inside the tray 11, a substantially box-shaped element 17 can be seen, corresponding to the shape of the bathtub and / or shower tray 1. This substantially box-shaped element 17 is hollow and has two access openings 18 for accessing its interior. For example, control elements, drive elements for the lifting or lowering mechanism 5, or the like, which are not shown, can be provided inside this interior. The substantially box-shaped element 17 is covered by the plate-shaped element of the base part 6 and sealed by inserting a seal 16. The base part 6 is releasably attached to the substantially box-shaped element 17.

[0040] Finally, in addition to the support elements 8, Fig. 4 also shows drain fittings 18 and the drain 14, which is designed for connection to a pipe system not shown, as well as support elements 19 which can be attached under the cup 11.

[0041] Such a bathtub and / or shower tray 1 is not only characterized by its extremely flexible application possibilities, but also has the particular advantage that it is completely barrier-free and can simultaneously serve as a fully-fledged bathtub and, moreover, any water in the tub can be safely drained away.
