BATHTUB AND / OR SHOWER TRAY

Description

[0001] The present invention relates to a bathtub and / or shower tray with a base section and a wall or side element that completely surrounds the circumference of the base section and is arranged substantially perpendicular to the base section, wherein the wall or side element is formed in multiple parts from substantially ring-shaped elements that can be fixed closely together, wherein all substantially ring-shaped elements surrounding the base section are movable relative to each other in the direction of a vertical extension of the bathtub and / or shower tray and relative to the base section, wherein at least one lifting and lowering mechanism articulated to the ring-shaped element that is movable furthest away from the base section is provided, wherein the base section is surrounded by a drainage channel having drain fittings and the ring-shaped elements are arranged to be retractable into the drainage channel.

[0002] Bathtubs and / or shower trays come in a wide variety of sizes, designs, and depths and can be found in almost every house or apartment. However, especially in modern homes, the desire of residents for a bathroom that includes both a bathtub and a shower tray is often not fulfilled due to limited space. Both bathtubs and shower trays have their advantages and disadvantages. For example, a shower tray makes it easy for the elderly and / or people with limited mobility to get in and out. On the other hand, a bathtub offers more comfort and ease of full-body cleansing, particularly for those with limited mobility or children. However, the high sides of a bathtub can make getting in and out difficult without assistance, especially for people with limited mobility.

[0003] To enable these individuals to enter and exit such a deep bathtub, bathtubs with entry openings or doors have already been provided, allowing users to easily get in and out. However, a disadvantage of such bathtubs remains the fact that a depth comparable to a conventional bathtub is not necessary for showering. Furthermore, even if a level or nearly level surface can be provided for showering, technical problems persist regarding water drainage, cleaning the entire bathtub and / or shower tray, and similar issues.

[0004] EP 3378366 A describes a bathtub and / or shower tray which can function as both a sufficiently deep bathtub 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, requiring the bathtub to be completely emptied before lowering the individual interlocking elements forming the tray to prevent water from overflowing, or it is also known that, when lowered, the tray-forming elements are lowered into a drainage channel in which drains are provided, or at least one drain is provided, through which the water is to flow away.A disadvantage of this type of design is that the profiles of the tub, which are lowered into the drainage channel, almost completely fill the drainage channel, thus massively hindering the rapid drainage of the water.

[0005] The CH-PS 52381 is a further development of a collapsible bathtub, which consists of a tub-shaped base element and telescopically sliding wall elements, which are held in place by means of support elements that can be clamped under the upper edge to prevent the individual elements from sliding into each other unintentionally.

[0006] The present invention therefore aims at such a bathtub and / or shower tray which is designed in such a way that its wall or side element height can be completely recessed into the floor and form 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.

[0007] In order to meet both requirements in one and the same bathtub and / or shower tray – namely, to provide a bathtub that is easy to get in and out of, and a shower tray that forms a level surface during showering, and a bathtub with sufficient depth to hold enough water for a full bath – it is therefore necessary to provide a bathtub and / or shower tray that can be adjusted to form a level surface with the surrounding bathroom floor and, moreover, ensures that water from the tub or water added during showering is safely and reliably drained away from the surrounding floor.To solve this problem, the bathtub and / or shower tray is essentially characterized by the fact that the drainage channel is formed from two interconnected drainage channel parts, a lower and an upper drainage channel part, that a plurality of support elements designed to support the essentially ring-shaped elements are provided in the lower drainage channel part, and that at least one drain connected to at least one water drain pipe is formed in the lower drainage channel part.Because the drainage channel is formed from two interlocking sections, a lower and an upper section, the essentially ring-shaped elements can be completely recessed into the upper section. When recessed, this creates a shower tray with a perfectly flat surface, flush with, for example, a bathroom floor. Furthermore, the lower drainage channel allows water from a filled bathtub or water that falls onto the flat surface during showering to drain downwards through the upper channel and then into a drain via the lower channel.This ensures that water does not unintentionally run into the bathroom or remain standing in a drain channel, as was the case with bathtubs according to the prior art. While these bathtubs could be lowered to create a flat surface, the channel into which the bathtub elements were recessed could not be completely emptied due to obstructions to the free flow of water from the tub components. The problems caused by standing water, hair, soap residue, and the like, as well as problems of unintentional water leakage into the bathroom with the well-known adverse consequences of a slippery floor, moisture-damaged bathroom furniture, and the like, can be reliably avoided with a design according to the present invention.

[0008] Interconnected drainage channel sections are understood to mean that the two drainage channel sections are separated by, for example, a step, a bevel, a cross-sectional narrowing or the like, but form a common water intake volume, in which the at least partially open top of the lower water intake volume simultaneously forms a virtual continuation of a bottom surface of the upper water intake volume.

[0009] A further safety feature, as provided for in the invention, is the design of a drain connected to water drainage pipes in the lower part of the drain channel. This ensures that the drain is located in the lowest part of the bathtub or shower tray and reliably prevents water from pooling in any part of the device.

[0010] By designing the bathtub and / or shower tray, as corresponds to a further development of the invention, such that the essentially ring-shaped elements are designed as interlocking essentially L-shaped individual profiles and that sealing elements, in particular ring-shaped seals, are provided between interlocking legs of the individual profiles, it is possible to form the tub from detachably connectable individual profiles, which is sealed in its erect state by inserting sealing elements between the individual profiles and furthermore ensures that water can pass between the individual ring-shaped elements in the lowered state of the essentially ring-shaped elements.Sealing is achieved through the weight of the individual elements, which are interlocked; a connection between the essentially ring-shaped profiles, for example by means of a flexible silicone element, is not necessary.

[0011] To ensure that water does not suddenly seep between all the ring-shaped elements connected only by seals when the majority of them are lowered, and that an excessive amount of water does not flow into the drainage channel, the lowering process is carried out in such a way that water first escapes between the bottom element and the first element, then between the first and second elements, and so on. This is achieved because, due to the water pressure, the lowest element is the first to disengage from the bottom element and subsequently reaches its desired flat or lowered state first.In this way, it can be prevented that excessive amounts of water escape simultaneously, and finally, as corresponds to a further development of the invention, the device can be further developed in such a way that a plurality of sensors are provided which control the water level in the drainage channel, the speed of lowering the individual ring-shaped elements, and the like, and in the event of too rapid a 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.

[0012] In practice, the essentially I-shaped elements usually correspond to an L rotated by 180°, or a kind of hook, so that the downward-facing edge of each element is essentially straight.

[0013] In order to prevent the individual essentially ring-shaped elements from bulging out or being pre-formed 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 the essentially L-shaped elements are at their maximum height extension or are interlocked, the invention is further developed in such a way that stiffening elements, which at least partially encompass the essentially ring-shaped elements, are provided on an outer circumference.By providing these at least partially enclosing stiffening elements on the outer circumference of the essentially ring-shaped elements, it is possible to reliably prevent the essentially ring-shaped elements from bulging outwards due to the water pressure prevailing inside the bathtub and / or shower tray. "At least partially enclosing stiffening elements on the outer circumference" means that the stiffening elements are arranged on the outside of the essentially ring-shaped elements, whether screwed to them, glued to them, formed integrally with them, the material being reinforced, or the stiffening element being incorporated into the material thickness, or the like. "Partially enclosing" means, particularly in the case of bathtub designs that are not circular but, for example, have an elliptical shape or the like, that the long sides or...The extended sides are formed with stiffening elements. Parts of the essentially circular elements that exhibit a relatively large curvature, such as head sections or the like, do not require any stiffening elements, as these are not accessible to a bulge or only to a very limited extent.

[0014] To provide a secure standing surface and, in particular, to prevent any risk of accidents, even when the individual, essentially ring-shaped elements are in the lowered position, the invention is further developed such that, in a lowered position of the ring-shaped elements, the upper drainage channel section is completely covered by the upper legs of the essentially L-shaped individual profiles. Because the upper drainage 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 inevitably form between the individual, essentially L-shaped individual profiles also allow the water to drain safely and reliably into the lower drainage channel section, thus preventing water from leaking out of the area of ​​the flat shower tray.The gaps form primarily because a bathtub wall is not inherently perfectly vertical, but rather has an inclined shape, tapering towards the base. As the bathtub is lowered, depending on the degree of inclination, a small gap inevitably forms between the upper legs of two adjacent, essentially L-shaped profiles. According to the present invention, this small gap serves as part of a water drain when the essentially ring-shaped elements are lowered.

[0015] In a further development of the invention, the bathtub and / or shower tray is designed such that the support elements are configured as support ribs or bearing studs. This ensures that, when the bathtub and / or shower tray is lowered, the essentially ring-shaped elements rest on the support ribs or bearing studs, preventing any obstruction of water flowing freely into the lower drain channel. To prevent water from accumulating on the bearing studs or support ribs, the design can be such that a drain is provided between more than two support ribs or a series of bearing studs. This drain is connected to a central drain located beneath the bathtub or shower tray, allowing water to flow into the central drain from multiple directions.Such a design not only ensures that large quantities of water can drain away quickly and reliably, but also, in particular, reliably prevents the drainage channel from overflowing.

[0016] In a further development of the invention, the support struts are designed as bridges spanning the lower drainage channel section and detachably fixed within it. This simplifies the device further, eliminating the need for multiple drainage openings. Instead, the entire lower drainage channel section is available to receive water, which can flow freely within it, thus ensuring rapid drainage through the designated drainage opening(s). Furthermore, by designing the support struts as detachably fixed, they can be easily removed for maintenance or cleaning purposes. This also ensures a hygienic design, as it prevents the accumulation of residues such as hair or similar substances on the struts.these can be cleaned quickly and easily.

[0017] For added safety of the bathtub and / or shower tray, the invention is designed such that the support struts have a number of recesses or notches corresponding to the number of ring-shaped elements. By providing a number of recesses or notches corresponding to the number of ring-shaped elements, the invention ensures that, when the bathtub and / or shower tray is lowered, each ring-shaped, essentially L-shaped element is positioned in one of the notches or recesses. This reliably prevents the individual, essentially ring-shaped elements from shifting relative to one another and thus also prevents the unintentional formation of larger gaps in the flat floor surface, which only has narrow drainage slots.

[0018] Similarly, in a further development of the invention, the design can be such that the support studs are arranged at intervals on a base surface of the lower drainage channel, and that a plurality of groups of support studs are provided, each group extending radially along the lower drainage channel and arranged side by side in a number corresponding to the number of annular elements. By arranging a plurality of support studs at intervals on a base surface of the lower drainage channel, it is possible to provide support studs for the essentially annular elements while simultaneously ensuring that the water drainage inside the lower drainage channel is not obstructed and that the water can flow through the space between the individual studs.By simultaneously arranging multiple groups of support studs extending radially along the lower drainage channel, and by ensuring that these groups have a corresponding number of support studs next to each other for the number of ring-shaped elements, multiple support points are provided for each individual ring-shaped element. This ensures that even when a load is applied to the top of the essentially ring-shaped elements, e.g., when the bathtub and / or shower tray is in the lowered position and being used as a shower tray, no unintentional tilting or deflection of the individual elements occurs, thus providing a smooth and level floor without any differences in level.

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

[0020] By arranging control elements, in particular those for controlling the raising and / or lowering of the essentially ring-shaped elements, inside the substantially hollow, box-shaped element, as is a further development of the invention, it becomes unnecessary to provide a separate control box for the control of the bathtub and / or shower tray. Naturally, the substantially hollow, box-shaped element can accommodate not only the control for adjusting the height of the shower tray and / or bathtub, but also the control of the quantity and / or temperature of the required water, various sensor elements, and the like. This allows for remote control operation of the bathtub and / or shower tray, whether via a mobile phone or other means, or for switching between a water supply for a bath or a shower, and so forth.Naturally, the classic operation using, for example, push buttons to raise or lower the tub or conventional faucets is also possible. Furthermore, all other components for the water supply, mixing valves, or the like can be contained within the hollow, box-shaped element. With this design, the fact that the essentially box-shaped element is covered by a detachably attached, essentially plate-shaped element ensures that no moisture can penetrate the interior of the essentially box-shaped element and that no locking or other fixing elements are visible on any surface facing the interior of the bathtub and / or shower tray. Finally, this design allows for easy cleaning of the entire base of the bathtub or shower tray.

[0021] By designing the device in such a way that the bottom part has a plurality of nozzles, in particular air and / or water supply nozzles, as corresponds to a further development of the invention, it is possible to use the bathtub and / or shower tray directly as a whirlpool or massage tub without having to make any changes to the essentially ring-shaped profiles or drainage channels.

[0022] If, as in a further development of the invention, the lifting and lowering mechanism is formed by at least two lifting cylinders that can be actuated electrically, hydraulically, or pneumatically, and in particular by remote control, one-sided lifting of the bathtub is reliably prevented. The design can be such that the respective lifting and / or lowering mechanism engages the uppermost, essentially ring-shaped element and causes it to lower or raise. It goes without saying that the uppermost, essentially ring-shaped element, as well as the drain channel section in the area of ​​the lifting and lowering mechanism, requires reinforcement to reliably prevent the elements, which are usually made of plastic, from tearing out.Considering that such stiffening elements can either extend over the entire circumference of the uppermost, essentially ring-shaped element and the drainage channel section, or are only formed locally and can be selected from any materials or possibilities, a more detailed discussion of these stiffening elements is unnecessary.

[0023] The entire bathtub and / or shower tray can be operated either via remote control or traditionally using control buttons and an electronic control system. Naturally, all variations of sensor control, control via mobile phone or remote control, pre-programmable filling and emptying times, and the like are possible. Since such control elements, regulating elements, and programmable components are familiar to the professionals, a more detailed discussion of them is unnecessary.

[0024] The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. These show Fig. 1 a view of the bathtub and / or shower tray according to the invention, Fig. 2 a side view of the bathtub and / or shower tray of Fig. 1 , Fig. 3 a top view of the bathtub and / or shower tray in the lowered state, and Fig. 4 an exploded view of the individual elements forming a variant of the bathtub and / or shower tray.

[0025] In Fig. 1 Generally, 1 denotes a bathtub and / or shower tray, which in this case is formed from five essentially ring-shaped elements 2 that can be slid into or out of each other. The essentially ring-shaped elements 2 are shown in the illustration of Fig. 1 The bathtub or shower tray 1 is shown in its fully extended position, creating a bathtub 1 with a conventional depth of between 35 cm and 50 cm. The height of the bathtub or shower tray 1 is adjusted by means of a lifting and lowering mechanism 3 acting on the uppermost ring-shaped element 2. The uppermost ring-shaped element 2 is reinforced to accommodate the lifting and lowering mechanism 3, and a reinforcing element 5 for the lifting and lowering mechanism 3 is provided in the upper drain channel 4. The bathtub or shower tray 1 according to Fig. 1 is designed in such a way that the lowest, essentially ring-shaped element 2 engages in a base part 6, wherein, according to the invention, the base part 6 is aligned with, for example, a bathroom floor, which is not shown, and is formed on the same plane in order to achieve a surface flush with the bathroom floor when the essentially ring-shaped elements 2 are pushed together.

[0026] In order for the essentially ring-shaped elements 2 to form a single plane with the base 6 of the bathtub and / or shower tray 1 when pushed together, a 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 ring-shaped elements 2. According to the invention, the drainage channel 4 is now designed such that it is formed from two interlocking drainage channel sections 4 and 7, a lower 7 and an upper 4 drainage channel section. A plurality of support elements 8 are provided in the lower drainage channel section 7, on which the individual essentially ring-shaped elements 2 rest when the bathtub and / or shower tray 1 is lowered. In the illustrated embodiment, the support elements 8 are designed as ribs that bridge the lower drainage channel section 7 and are inserted into recesses 9 of the lower drainage channel section 7.The support elements 8 can also be designed with knobs or as screwed-in or tightly inserted ribs or the like in corresponding recesses. The support elements 8 further have a number of ribs 10 corresponding to the number of essentially ring-shaped elements 2, in order to enable the individual elements 2 to rest without displacement when the bathtub and / or shower tray 1 is lowered.

[0027] 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 have a very low weight, and thus the forces acting vertically on the bathtub or shower tray 1 are relatively small.

[0028] In Fig. 1 The cup 11 with the drainage channels 4, 7 is further equipped in the area around the upper drainage channel part 4 with feet, in particular height-adjustable feet 12, in order to provide a primarily 100% horizontal design of the bathtub and / or shower tray 1.

[0029] Finally, as is also not shown in the present training, the bathtub or shower tray 1 can be covered on its outside with a cover element to increase the aesthetics.

[0030] In Fig. 2 are essentially the reference symbols of Fig. 1 retained, whereby the bathtub and / or shower tray 1 is shown as a side view, with the design located under the tray 11 also being shown. In addition to the features already in Fig. 1 The elements shown are Fig. 2 Furthermore, a drive unit 13 for the lifting and lowering mechanism 3 is shown schematically, as well as a drain 14 so that the water flowing into the lower water drain channel 7 can safely drain away.

[0031] In Fig. 3 The bathtub and / or shower tray 1 is depicted in its folded or nested state of the ring-shaped elements 2, wherein the base section 6 is arranged on a plane with the essentially ring-shaped elements 2 recessed in the drainage channel 4, and the respective upper legs 15 of the essentially L-shaped profiles of the essentially ring-shaped elements 2 are designed such that the drainage channel 4, 7 is completely covered by these upper legs 15, thus minimizing the risk of accidents, particularly when stepping onto the base element 6 of the bathtub and / or shower tray 1. It goes without saying that such a design of the bathtub and / or shower tray 1 can be used directly as a shower, with wastewater from showering flowing between the essentially ring-shaped elements 2 into the drainage channel 4, 7 and from there being carried away via the drain 14.

[0032] In Fig. 4 Figure 1 is an exploded view showing the individual elements that make up a variant of the bathtub and / or shower tray 1. In this exploded view, in addition to the elements essential for the construction of the bathtub and / or shower tray 1, other elements such as a height adjustment for the feet 12, seals for the reinforcement elements 5 of the lifting and lowering mechanisms 3, fixing elements, and the like are also indicated, but these are not essential for the functioning of the bathtub and / or shower tray 1 and are therefore not described separately.

[0033] In detail, it is from Fig. 4 It is evident that each essentially ring-shaped element 2 is formed with an upper rim 15, into which upper rim 15 a seal 16 is inserted. However, the essentially ring-shaped elements 2 can also be essentially Z-shaped, with an additional lower rim 15. Fig. 4 The edge, not shown, would be formed. This essentially Z-shaped design of the essentially ring-shaped elements 2 is, on the one hand, more difficult to clean, since water always remains in the lower groove of the Z, and on the other hand, the free drainage of water is somewhat impeded. With the essentially L-shaped or Z-shaped design of the essentially ring-shaped elements 2, two vertically successive essentially ring-shaped elements 2 are connected only by the inserted seal 16, so that during lowering, the elements 2 become disengaged and water passes between the essentially ring-shaped elements 2. To prevent bulging of the essentially ring-shaped 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 substantially ring-shaped element 2. Alternatively, the elements 20 could also be designed as material reinforcements.

[0034] Furthermore, it is from Fig. 4 It is clearly evident that the uppermost ring-shaped element 2 has a significantly wider rim 15 of the essentially L-shaped element than the other essentially ring-shaped elements 2. Stiffening elements 5 are provided below this wide rim 15, through which, as well as through the rim 15, the lifting and lowering mechanisms 3 pass to enable the raising and lowering of the bathtub and / or shower tray 1.

[0035] Inside the cup 11, a substantially box-shaped element 17, corresponding to the shape of the bathtub and / or shower tray 1, is visible. This substantially box-shaped element 17 is hollow and has two access openings 18 to allow entry into its interior. Control elements, drive elements for the lifting or lowering mechanism 5, or the like, which are not shown, may be provided in this interior. The substantially box-shaped element 17 is covered by the plate-shaped element of the base 6 and sealed by inserting a gasket 16. The base 6 is detachably attached to the substantially box-shaped element 17.

[0036] Finally, the Fig. 4 In addition to the support elements 8, drain fittings 18 and the drain 14, which is designed for connection to a pipe system not shown, as well as support elements 19 that can be attached under the cup 11, can be removed.

[0037] Such a bathtub and / or shower tray 1 is characterized not only by an extremely flexible range of uses, but also has the particular advantage that it is completely barrier-free and can serve as a full-fledged bathtub, and moreover, any water in the tub is safely removed.
