Description

The utility model relates to oval-shaped wall-mounted bathtubs.

For wall baths made of cast marble of a rectangular shape, for example: [https://axop.su/item/vanna_estet_delta_170h80/], due to the presence of angular support legs, as well as due to the thick front wall, such technical problems are not typical , as for oval-shaped bathtubs, such as, for example: "Santechnika Life" Cast marble Savannah wall-mounted bathtub 160 (159x86cm) [https://moskva.regmarkets.ru/product/y984c6013d43c94ba9827d47bc163c415/].

When manufacturing a wall-mounted bathtub from cast marble, production is faced with the problem of deformation of a thin front wall that occurs during polymerization with shrinkage of the polyester resin included in the mixture during mold casting.

To solve the problem today, conductors are used in which the final polymerization takes place with the cooling of the product after removal from the mold (the isotherm during chemical polymerization reaches 60 degrees Celsius).

This greatly complicates the production process.

In addition to bathtubs made of cast marble, for wall-mounted oval-shaped bathtubs, for example, made of acrylic (see Acrylic bathtub Art&Max AM-206-1700-800 [https://artmax.su/catalog/vanny/pristennye/1537/] is also characterized by another set of technical problems.

The closest analogue to the claimed solution among wall-mounted bathtubs can be noted the BATH "ATRIA WALL" [https://www.astraform.ru/production/bath/bath_100.html#], publ.: 04/12/2018. (3D bath model is available on the same page).

All oval-shaped wall baths are characterized by the following technical problems.

The weakest point of the wall bath is the upper edge of the front wall.

The upper edge of the thin front wall has a high risk of damage already by the user during operation.

The user, getting out of the bath, grabs the thin side with one hand, and since there is nothing to grab on to the wall with his hand (you can only rest against the edge of the back wall of the bath at the time of getting out of it, and you can’t hold on to the tap), the user often grabs the upper edge of the anterior wall. And, if the weight of the user is large or the effort expended on lifting at the moment of grasping by hands is sharp and strong, the upper edge of the front wall of the bath (if it is not made of cast marble) may break off or form a crack. The presence of water at such moments in the bath only increases the load on the front wall.

Therefore, even sudden loads (jumping in a bathtub or inside a bathtub of a heavy person) while simultaneously grasping the edge of the front wall can lead to the formation of cracks and chips in the front wall area of bathtubs not made of cast marble, incl. and not only in its upper part, but also at the bottom of the bath.

Thus, due to the presence of a weak point near the wall bath in the form of a thin front wall, and also due to the fact that this section of the wall is subject to sharp loads, today the problem is how to strengthen the front wall of the bath without worsening its external aesthetic view.

Another technical problem is the safety of the user during the operation of the bath. As already stated above, at the moment of getting up from the bath or at the moment of entering the bath, the user is forced to grab with his hand or both hands on the edge of the front wall, since there is nothing else to grab with his hand.

If the bath is slippery, the user's grip is not secure. There is a risk of slipping and not holding the fingers of the hand or hands over the edge of the front wall, since it is also slippery.

Another technical problem specific to the prototype is the presence of supporting walls on which the tub rests.

These supporting walls are located along the perimeter of the bath bottom. They put the bath on the floor. When the bath is located on a surface that is not perfectly flat, only parts of the bath walls can bear the load, and even those that are not intended for this (for example, decorative bath edges). As a result, the bathtub, when installed on a not perfectly flat surface without additional legs, can be prone to fracture, and a bathtub made of cast marble will experience maximum loads at the slightest misalignment.

In addition, the presence of additional supporting walls in the near-wall part increases the total weight of the bath and complicates its design. Meanwhile, for example, cast marble bathtubs are very heavy and reducing their total weight while maintaining strength is the main technical problem that also needs to be solved.

The purpose of the utility model is to solve the above technical problems.

The technical result is to increase the strength of the front wall of the bath, as well as to increase the safety in the operation of the bath in comparison with the prototype.

The specified technical result is achieved due to the fact that a wall-mounted bath of an oval solid-cast shape is claimed, having a bath tank with a bottom and a central drain hole, side and front walls, characterized in that on the edge in the upper part of the front wall there is an outward-facing ledge with a smoothly changing widening , which has a maximum thickness in the middle of the ledge, and on the lower side of the bottom of the tub there are transverse thickenings with a flat base adjacent to the inner side of the front wall.

Preferably, one of the thickenings on the lower side of the bottom of the bath is made in the area of the drain hole.

Preferably, the extreme thickenings on the lower side of the bottom of the bath are made as support.

Preferably, the end edges of the side and front walls are at the same level.

Preferably, the edge in the upper part of the front wall has an inwardly facing bevel with a smoothly varying widening of the bevel plane, which has a maximum thickness of the bevel in the middle part.

Implementation of the utility model

Wall bath oval solid-cast form consists of a tank 1 bath with a bottom 6 and a central drain hole 10, side 2 and front 3 walls (see Fig.1 - Fig.3, Fig.5 - Fig.7).

Making the bathtub solid is an important attribute to increase its safety and strength of the walls, since when making the bathtub consisting of parts, the latter are connected to the main bathtub (for example, bathtub handles or support legs) by means of fasteners (bolts, nuts). Meanwhile, under these fasteners, it is necessary to make through holes in the walls of the bath, which in itself leads to the appearance of chips and cracks in them. The fasteners themselves are also less durable than the material of the bath (for example, if the bath is made of cast marble. Therefore, a non-solid bath in itself will be less durable and less safe than a solid one.

What is new is that on the edge in the upper part of the front wall 3 there is an outward-facing ledge 8 with a smoothly varying broadening, which has a maximum thickness in the middle of the ledge, and on the lower side of the bottom 6 of the bath there are transverse thickenings 5 with a flat base adjacent to the inner side front wall 3.

The addition of a ledge 8 on the edge reinforces the upper part of the front wall 3 of the bathtub with a stiffening rib and at the same time not only maintains an aesthetic appearance, but also provides an increase in safety during the operation of the bathtub. This is due to the fact that the ledge 8 with a smoothly changing widening is also at the same time a handle that makes it easier for the user to get out of the bathroom, since it is convenient to grab it with your fingers.

Even if the bath is slippery, the user's grip will be more secure than in the prototype. This reduces the risk of falling in the bathtub and thus also increases safety when using the bathtub.

Due to the presence of an outward-facing ledge 8 with a smoothly varying broadening, which has a maximum thickness in the middle of the ledge, the weak point of the upper edge of the thin front wall 3 increases in proportion to the widening of the ledge. The closer to the weak point, the thicker the ledge 8, and in the weakest point - the middle part of the ledge 8, its maximum thickness.

And due to the fact that transverse thickenings 5 with a flat base are made on the bottom side of the bottom 6 of the bath, the load from the side walls 2 and front 3 of the bath can be removed, and the entire mass of the bath can be redistributed to the flat bases of the thickenings 5, which, when installing the bath (see Fig. 4) put on supports (blocks 11, bricks or a metal frame with supporting legs). For this reason, the bulges 5 are made with a flat base for ease of installation on the supports 12. For example, such support bulges 5 can be made at the edges on the underside of the bottom 6 of the tub.

At the same time, the front 3 and side 2 supporting walls remain suspended during installation and only closely adjoin the edges to the floor 13, which creates the aesthetics of a free-standing bathtub, as if resting on the side 2 and front 3 walls. It also eliminates the problem associated with the location of the bath on a surface that is not perfectly flat, where the load is carried only by the supporting parts of the transverse thickenings 5 of the bottom 6 of the bath, and the decorative sides of the bath are not loaded. As a result, the bath, even when installed on a not perfectly flat surface, is not subject to fracture.

And adjacent to the inner side of the front wall 3, transverse thickenings 5 with a flat base form additional stiffening ribs in the zone of their junction with the inner part of the wall 3, which provides increased strength of the front wall 3 in its lower part and reduces the load on the front wall 3 at the moment when the tub is filled with water.

Thus, due to the possibility of the bottom 6 of the bath resting on the supports 11, the load is redistributed from the side 2 and front 3 walls to the bottom 6 of the bath, and also due to the strengthening of the strength of the front wall 3 of the bath with stiffening ribs (ledge 8 and adjacent to the inner side of the front wall transverse bulges 5 with a flat base on the bottom), the claimed bath reduces the risk of damage by the user during operation than the prototype. And therefore, even sudden loads (jumping in the bathtub or inside the bathtub of a heavy person) with a simultaneous grip on the edge of the front wall 3 can already to a lesser extent lead to the formation of cracks and chips in the area of the front wall of the bathtub (near its upper part and at the bottom). All this increases the safety of using the bathroom as a whole, since in the event of chips and cracks during operation, water can flow out of the bath and flood the neighbors from below.

If there is an additional thickening 9 on the lower side of the bottom 6 of the bath in the area of the drain hole 10, the front wall 3 is further reinforced in the middle part in the area of adjacency to the bottom 6. This also reduces the risk of damage to the bath by the user during operation.

The redistribution of the load from the supporting walls (as in the prototype) to the transverse thickenings 5 of the bottom 6 eliminates the need to create additional supporting walls from the side of the rear wall 7, which are located along the perimeter of the bath bottom and make a technological cutout in them. This reduces the weight of the bath, especially if the bath is made of cast marble, and also simplifies the manufacturing process.

In addition, it eliminates the need for a perfectly flat and perfectly level surface for the bathtub, since the leveling of the bathtub is possible due to the supports.

Additional reinforcement of the front wall is also ensured by the execution on the edge of the front wall 3 of an inward-facing bevel 4 with a smoothly changing widening of the bevel plane, which has a maximum thickness of the bevel 4 in the middle part, where the weak point of the front wall 3 is located. Thus, the bevel 4 acts as a stiffening rib already from the inside of the front wall 3 baths. The ability to perform such a bevel 4 becomes possible due to the implementation of the ledge 8, which thickens the front wall 3 from the outside, so its execution is thinner due to the bevel 4 from the inside does not affect the strength of the edge in the upper part of the front wall 3. In addition, the presence bevel 4 on the inside makes it easier for the user to grab the ledge 8 by hand, since the bevel 4 reduces the thickness in the area of the upper part of the front wall 3. Moreover, where the thickness of the ledge 8 in the middle part of the wall increases, the bevel 4 also becomes thicker, compensating for the broadening of the ledge 8 .

Thus, the presence of the bevel 4 further reduces the risk of falling in the bathtub and thus also improves safety in the operation of the bathtub.

The claimed bath is used as follows.

The location of the bath is selected at the wall 14 (see Fig.8) to create the appearance of touching the edges of the bath wall. To do this, in the manufacture of the bath itself, it is preferable to have the end edges of the side 2 and front 3 walls at the same level.

At the installation site of the bath (see Fig.4) prepare supports 11 (blocks, bricks or a metal frame with support legs), on which the bath is supported by transverse thickenings 5 with a flat base. If necessary, the support 12 is also made under the transverse thickening 9 with a flat base, located in the area of the drain hole 10, which reduces the load on the bottom of the tub 6 and also increases the risk of damage to the tub by the user during operation.

For testing, a prototype was made according to the utility model.

The test was carried out in comparison with a control sample, which was purchased as a product BATH "ATRIA WALL" [https://www.astraform.ru/production/bath/bath_100.html#].

The usability test was carried out by interviewing visitors to the plumbing store, who were asked to first climb into the bath of the control sample, and then into the bath of the prototype.

All visitors out of 50 respondents noted the inconvenience of holding the edge of the bath in the control sample, and the convenience of holding the ledge in the prototype. At the same time, 8 people fell in the control sample, not holding onto the edge with their hands, despite the fact that they climbed into it in shoes. No falls were noted in the prototype.

During stability tests, both tubs were tested for their ability to withstand concentrated loads, front wall edge loads, and the resistance of the front wall to chipping and cracking during operation.

The control sample was installed on a flat bathroom floor with supporting walls. First the floor was leveled, then the bath itself. Having achieved an accurate alignment of the control sample, we began testing.

The prototype according to the utility model was installed on the transverse thickenings 5 on the support blocks according to the scheme as in Fig.4 on a normal surface (not perfectly flat). Only the bath itself was leveled.

Both baths (prototype and control) passed the static load test.

Tests for the stability of the front wall of both baths to withstand the load were carried out by fixing the moment of occurrence of cracks and chips. For this, in the middle part, closer to the upper edge, a jack was installed between the two walls, under the base and head of which boards were placed.

Tests showed that the prototype began to crack in the front wall at a load 1.5 times greater than in the control sample. In addition, in the control sample, 4 cracks appeared at once in different directions on the front wall and 2 cracks on the back, while in the test sample only 1 vertically oriented crack was formed on the front wall 4 cm long, and at a much higher load.

Thus, the tests have shown that the prototype has a higher strength of the front wall of the bath and better safety in the operation of the bath in comparison with the prototype.
