The invention relates to the field of construction, namely, to designs of floating pools for bathing people.
The concept of floating pools appeared in the late 19th century, when the banks of the Hudson were built floating baths. Currently there is a growing need for people to swim, especially for the urban population. This requires more places for water sports and entertainment. Floating pools are a promising alternative or complement to stationary ground pools. The construction of floating pools more economically, they can be mobile or portable and you can make them indoor. Floating pools allow you to improve the infrastructure of cities and regions, to improve tourist attraction with regard to the accompanying construction of restaurants, cafes and other places to relax.
Known floating pool with a frame of sealed hollow plastic tubes, walls, floats and installed on the frame boards to support the swimmers in the pool (CN 202559786, 2012).
The disadvantage of the pool design is the complexity and security of the swimmers.
Known floating pools representing a grid or lattice with attached floating elements (CN 102373813; CN 102505872; CN 201011153).
The drawback of this is of onstructi is low the safety of swimmers, associated with the possibility of injury while resting in the water on a grid or lattice, the disadvantage of such support, and the inability of such pools in reservoirs with water that does not comply with sanitary norms.
Known floating pool, designed in the form of a rigid containers for swimming with lining the paths and supported afloat hollow barrels (CN 202055579, 2011).
This pool complex in design and costly to manufacture.
Known floating pool, made of glass and equipped with pontoons filled with floating balls (CN 202164840, 2012).
The disadvantages of the basin should be attributed to the high costs of manufacture and operation, the impossibility of disassembly and the difficulty of moving such a pool.
Known floating pool with a plastic or rubber membrane, supporting the pontoons and device for filtering external water to fill the pool (CN 102797370, 2012).
This design does not provide stable maintenance of a specified level of depth, because of the lack of rigidity of the material of the bottom sags under the weight of people standing on their feet, and water filtration leads to additional water in the pool.
The closest technical solution to offer is a floating pool that contains the container bottom and connect the major one side with the upper edge of the tank and spaced along its perimeter pontoons (EN 2004111754, 2005).
This design does not allow a person (the bather) to stand confidently on the bottom of the tank basin due to its flexibility. In addition, the lack of rigidity of the bottom, leading to deflection, increases the depth of the seat support person, and in the case of large specific load can rupture the bottom of the pool.
The present invention is to improve the safe operation of the pool and usability.
The technical result achieved by the invention is the regulation of the rigidity of the bottom floating pools, made of flexible membranes depending on the load on the bottom, increasing the reliability of mounting of the pontoons and the stability of the pool water.
The problem is solved and the technical result is achieved by the fact that a swimming pool is equipped with stretch marks, binding edge of the bottom of the vessel at its perimeter with side pontoons, the opposite side of their attachment to the container, and the container is made in the form of a rigid frame with attached sheath of flexible material, and mounting the pontoons to the vessel performed articulated with the possibility of rotation of the pontoons in the vertical plane. Stretch marks can be made of flexible material or in the form of a rigid rod with a swivel mount to the bottom and pontoons.
According to the second variant of the invention, the melt is in store pool equipped posted on the outside of the bottom of the vessel a flexible support element and stretch marks, connecting the supporting element with the side pontoons, the opposite side attaching them to the frame, and the container is made in the form of a rigid frame with attached sheath of flexible material, and mounting the pontoons to the vessel performed articulated with the possibility of rotation of the pontoons in the vertical plane.
The supporting element may be in the form of a grid or intersecting strips or in the form of a continuous web. Stretch marks can also be made of flexible material or in the form of a rigid rod with a swivel mount to the supporting element and the pontoons.
These distinctive features significant.
Performing mounting pontoons pivotally with one end while fastening the opposite edge of the stretch marks associated with the bottom or supporting element, ensures reliable fixing of the pontoons and at the same time allows you to automatically increase the rigidity of the bottom with the increasing number of swimmers due to the tension of the bottom of the stretch marks with the extra load in the pool. This design increases the stability of the pool water with agitation and asymmetric load on the edges and the pontoons the pool.
The drawing shows a General view of the pool from the bottom.
The pool contains the tank 1 and connected on one side with the upper edge 2 of the container 1 is located on the perimeter of the pontoons 3. Edge 4 of the bottom 5 of the tank 1 at its perimeter associated with stretch marks 6 with the side pontoons 3, the opposite side of their attachment to the container 1. The container 1 is made in the form of a rigid frame 7 with attached sheath of flexible material 8. The attaching pontoons to the vessel performed hinge (not shown) to allow rotation of the pontoons 3 in the vertical plane.
According to the second variant of the invention with the outer side of the bottom 5 of the container 1 is placed a flexible supporting element 9, which may be in the form of intersecting strips 10, or mesh (not shown), or solid fabric 11. Stretch marks 6 can be made flexible or rigid rods with swivel mount (not shown) to the supporting element 9 and the pontoons 3. The pontoons 3 can be made in the form of a frame 12 to which is attached a hollow sealed cylinders 13 and the deck 14. All pontoons are independent of each other.
The pool operates as follows.
The pool is placed in the waters of the reservoir and fill with pure water. The tank 1 is supported on floating pontoons 3. The tension plate 5 due to the depth of immersion of the cylinder 13 related stretch marks 6 with the edges of the bottom. In the variant with the supporting element 9, the rigidity of the bottom 5 is determined by the tension element 9.
When immersing one or more persons in the water increases the force on istula pool side at the inner edge of the pontoons 3, and there is a torque, contributing to the revolution of the pontoons 3. This force is transmitted by a pontoon on stretch marks 6 and increases the tension of the bottom 5 or supporting element 9. Thus, immersion of a person in the water leads to the automatic gain tension of the bottom of the pool, to increase the rigidity of the whole structure of the capacity of the basin and the alignment position of the pool in the water. And the more people are in the pool, the more it sinks in water, causing the desire of the pontoons to be rotated about the hinged attachment to the tank 1. Thereby increasing the tension of the bottom 5 or supporting element 9, increasing their rigidity and preventing the deflection of the bottom of the pool, drawing people to him. In the case of tilting of the basin in water (e.g., waves or excessive load on one edge) submersible in water pontoon transmits the increasing tension through stretching 6 and the bottom 5 or supporting element 9 on opposite spaced pontoons, preventing them from coming out of the water and reduce the buoyancy of the pool.
