[0001] DESCRIPTION

[0002] APPARATUS WITH CURVES THAT RETAINS A QUANTITY OF RAIN WATER ON ITS SURFACE FOR THE EXTERIOR SURFACE OF ROOFS

[0003] Technical Area

[0004] This invention relates to an apparatus with curves that is used to hold some of the rainwater falling on its surface, thanks to the apparatus with curves on the outer surface of the roofs of buildings and / or structures in open environments, that is, in the open air, which is in contact with the open air.

[0005] Known State of the Technique

[0006] The human population has increased from the past to the present. Due to the increase in the human population, the number of structures such as houses, workplaces, and public buildings necessary for humans has increased, the population of farm animals raised to feed the human population has increased, and due to the increase in the farm animal population, the number of structures necessary for farm animals has increased. As a result of the increase in the area covered by all these buildings and structures in our world with the increase in the human population; the total amount of land and similar water permeable areas with or without plants on them, forest areas with water permeability and the amount of land used for plant cultivation for agricultural production is decreasing.

[0007] Plants help purify the air by increasing the amount of oxygen in the air and decreasing the amount of carbon dioxide. A negative effect of the decrease in the total surface area of all plants, including agricultural and forest areas, is that it causes an effect towards the disruption of the balance of oxygen and carbon dioxide in the air.

[0008] One effect of the decrease in the total surface area falling on all plants, including children's parks, coastlines and other various places, such as soil and similar water permeable areas with or without plants, and agricultural and forest areas with water permeability, is that when it rains, especially in areas with a lot of buildings and structures, the leakage of the rain into the underground is prevented due to the impermeable grounds, and therefore rainwater accumulates on the surface, causing negative effects such as floods and inundations.

[0009] The increase in the area covered by buildings and structures in our world and the decrease in the total area of land and similar areas with or without plants, forest areas and all plants including plant cultivation for agricultural production, is a result of the increase in the amount of dust in our world and the amount of dust in the air, because plants have the ability to absorb dust and the amount of dust increases as a result of the decrease in the areas where plants are located. An important problem caused by the increasing amount of dust in our world is the decrease in air quality. For the reasons explained, it is of great importance to retain some of the rainwater on the outer surface of the roofs and allow it to evaporate naturally there, and to make this practice widespread.

[0010] Roofs are the uppermost part of buildings and structures and basically serve to protect the buildings and structures they are on from precipitation and climate conditions such as heat and cold. In addition to these main functions, there are also methods to obtain additional benefits from roofs, and some of these are; collecting and storing rainwater falling on roof surfaces, obtaining energy with solar panels placed on roofs, installing green roof samples on roofs, and performing agricultural activities on roofs, which provide additional benefits in addition to the basic feature of roofs. Thanks to these additional benefits, more benefits are obtained from the unit surface area.

[0011] In order to prevent the roofs of buildings and structures located in regions with high annual snowfall in our world from being damaged by snowfall and to prevent the risk of collapse due to the accumulation of snow on the roofs, usually steep roof types with a high slope to the ground are preferred, in this way, the snow is ensured to slide off the roofs and the accumulation of snow on the roofs is prevented. In regions with low annual snowfall compared to regions with high annual snowfall in our world, since the possibility of roofs being damaged by snowfall is lower, medium-sloped and / or low- sloped roof types with a lower slope to the ground are generally preferred.

[0012] Roofing materials and / or roofing materials currently used on the market are designed to quickly and rapidly remove rainwater from roof surfaces.

[0013] Green roofs can be simply defined as growing plants on roofs. Green roofs are seen on some of the roofs of buildings and structures in our world. In order for green roofs to occur, the necessary components must be installed on the waterproofing layer and appropriate conditions must be provided. One of the benefits of green roofs is that they reduce the amount of rainwater to be transmitted to stream beds, sewage and similar systems by retaining some of the rainwater within themselves, thus reducing negativities such as spates and floods. Another benefit of green roofs is that they absorb some of the dust in the air thanks to the plants they contain, and contribute positively to the increase in air quality. Another benefit of green roofs is that they contribute to the positive change of air quality, especially in areas where there are many buildings and structures such as cities and industries, by giving oxygen to the atmosphere thanks to the plants they contain.

[0014] Although there are varieties of green roof systems and different definitions of green roof systems, some similarities can be seen in the basic installation of green roofs. These similarities generally consist of components consisting of; waterproofing layer, root holding layer, drainage layer in some green roof varieties, plant carrier layer and plants, on the roof of the building or structure where the green roof is planned to be installed. The plant carrier layer is usually composed of soil and similar substances and has plants on it. In addition to layers such as waterproofing layer, root holding layer, drainage layer, plant carrier layer on green roofs, wind erosion prevention material, barrier and other materials can also be used on green roof varieties and their application types. The fact that various components, namely layers, are needed for the formation of green roofs and that they usually require technical expert support in their installation increases the cost of green roof systems. The phrase referred to as technical expert support is used to express the need for specialized people such as agricultural engineers, botanists, landscape architects, civil engineers, architects and / or masters specialized in green roof installation in the installation of green roofs.

[0015] Since green roofs will create additional weight on the roofs of the buildings and structures on which they are located, the roofs on which the green roofs will be installed must be resistant to this additional weight or, if they are not sufficiently resistant, must be made resistant to this additional weight; these requirements make it difficult for green roof systems to become widespread, and making roofs resistant to the additional weight increases the cost of green roof systems.

[0016] Some of the green roof varieties are referred to as intensive green roofs, which are cultivated intensively and contain a word of non-Turkish origin in their names, and these green roofs create a heavy load on the roofs due to their high weight per unit area, are not possible for everyone to use due to their high costs, require periodic maintenance due to the high variety of plants, the cultivation of plants that need maintenance, and similar reasons. Some green roof varieties are referred to as extensive green roofs, which are cultivated sparsely and contain a word of non-Turkish origin in their names, and these green roofs create less load on the roofs due to their lower weight per unit area than intensive green roofs, and again, since their cost is lower than intensive green roofs, they can be used by more people, require less maintenance than intensive green roofs due to the limited variety of plants compared to intensive green roofs, the cultivation of plants that are resistant to natural conditions, and similar reasons.

[0017] In the different climates of our world, a common feature of the roofs of buildings and structures is that the rain that falls is quickly and rapidly removed from the roofs. In this case, especially in areas where there are many buildings and structures, the leakage of rainwater underground is prevented due to impermeable floors and in places where the infrastructure is inadequate, and thus rainwater accumulates on the surface, causing floods and similar negativities.

[0018] As it is known, water boils at 100 degrees Celsius at sea level, but it can evaporate at any temperature. As the open surface area of water increases, that is, the surface area in contact with the air increases, evaporation increases and the evaporation event occurs on the water surface. As is the case with the currently used roofing materials and / or roof covering materials, if rainwater is removed from the roof surfaces quickly and rapidly, especially in areas where there are many buildings and structures, and if it is not stored with any storage method around the buildings and structures on which they are located, more rainwater will be transmitted to stream beds, sewage systems and similar systems, and the probability and rate of occurrence of negativities such as spates and floods will increase. If some of the rainwater is kept on the outer surfaces of the roofs that are in contact with the open air for a while and its evaporation is ensured; the amount of rainwater to be transmitted to stream beds, sewage systems and similar systems will be reduced, and the probability and rate of occurrence of negativities such as spates and floods will decrease.

[0019] Purpose of the Invention

[0020] The present invention relates to an apparatus with curves that retains a quantity of rain water on its surface for the exterior surface of roofs, which meets the above-mentioned requirements, eliminates the disadvantages of the currently used systems and brings additional advantages, is designed to retain a certain amount of the falling rainwater on its surface.

[0021] The invention is generally aimed at reducing negativities such as spates and floods by reducing the amount of rainwater to be transmitted to stream beds, sewers and similar systems, thanks to its ability to retain a certain amount of the falling rainwater on its surface.

[0022] Another benefit that the invention will provide is that it will provide a natural growth environment for lichens and similar small and short plants, especially in rainy and humid weather, without the need for any human intervention and maintenance, thanks to the fact that it will hold some of the dust in the air on its surface over time, and it will contribute positively to the increase in air quality by ensuring that some of the dust in the air is absorbed thanks to these small and short plants.

[0023] Another benefit of the invention is that it will contribute to a positive change in air quality, especially in areas with many buildings and structures, such as cities and industries, by giving oxygen to the atmosphere thanks to the lichens and similar small and short plants on it.

[0024] The primary purpose of the invention, designed with the stated objectives, is to reduce the negative effects such as spates and floods by creating the conditions to retain some of the rainwater on its surface; and by reducing the amount of rainwater to be transmitted to stream beds, sewage systems and similar systems.

[0025] For this reason, the invention has the feature of holding a certain amount of rainwater on its surface through the apparatus with curves on the roof and does not require any other mechanisms to hold the rainwater.

[0026] Another important purpose of the invention is to provide additional benefits in addition to the main tasks of roofs, which are to protect the buildings and structures they are on from precipitation and climate conditions such as heat and cold. The additional benefit mentioned is that by keeping a certain amount of rainwater on its surface with the apparatus having curves, a certain amount of rainwater is kept on the apparatus having curves for a while and evaporating it, the amount of rainwater to be transmitted to stream beds, sewage systems and similar systems will be reduced, and the probability and rate of occurrence of negativities such as spates and floods will be reduced, thus, an increase in the variety of additional benefits is provided by adding a new one to the methods of providing additional benefits from roofs. Another important purpose of the invention is to make it easy to install on the roofs of buildings and / or structures, thanks to the curves on the apparatus that are used to hold a certain amount of rainwater on its surface for the outer surface of the roofs, the elevation strips that prevent water passage, the tapered parts and the slopes towards the tapered part, which are produced as a single piece as a whole, thus providing ease of installation.

[0027] Another important purpose of the invention is that the apparatus, which has curves for holding a certain amount of rainwater on its surface for the outer surface of the roofs, holds a certain amount of rainwater on its surface and provides a natural growth environment for lichens and similar small and short plants without the need for any human intervention and maintenance, thus providing ease of use.

[0028] Another purpose of the invention is to contribute positively to recycling by offering a new area of use for plastic and similar materials that are recycled and / or planned to be recycled, thanks to the possibility of being produced from recycled plastic and similar materials.

[0029] Another purpose of the invention is to ensure that rainwater is easily retained on the apparatus. This purpose is achieved by ensuring that the rainwater falling on the apparatus is transmitted to the curves by means of the apparatus having curves that are used to retain a certain amount of rainwater on its surface for the outer surface of the roofs, thanks to the apparatus having curves from the upper part facing upwards towards the ground and by means of the tapered parts combined with the curves of the apparatus and by means of the tapered parts being curved from the upper part facing upwards towards the ground. When the level of the deepest point of a curved part on the apparatus and the curve depth level of the tapered part combined with the same curved part are compared to the ground, the level of the curve depth is lower, that is, closer to the ground, thus ensuring that rainwater fills the curve. A water passage preventing elevation strip surrounds a part of the curve it is connected to in a way that creates an elevation, thus preventing water passage from places where it is not desired to flow. All of the water passage preventing elevation strips with the same name on the apparatus are parallel to the ground and have exactly the same features and dimensions. When rainwater falling on the surface of the apparatus fills one or more of the curves, the rainwater will be directed towards the tapered parts combined with the curves due to the elevation differences between them and will be drained from the right and left sides of the tapered parts close to the curve and excess water will be discharged, the rainwater that is filtered from the right and left sides of the tapered parts close to the curve will move to flow towards another curve located below, the downward flow of the rainwater will continue by reaching the region and vicinity of the most extreme, that is, the most acute part of another tapered part located below, and since the region and vicinity of the most extreme, that is, the most acute part of this tapered part is lower in elevation than the region above it, and thanks to its design as having entered a certain amount into the apparatus and the slope towards this part, the rainwater that is filtered and flows from above will flow over the region and vicinity of the most extreme, that is, the most acute part of the tapered part, and will be transmitted to the curve; when the curve to which rainwater is transmitted is full or is already full, rainwater will flow by filtering from the right and left sides of the tapered part close to the curve and will move to flow towards another curve located below and the system will continue throughout the apparatus in this way. All curves with the same name on the apparatus with curves have exactly the same properties and dimensions. All tapered parts with the same name that are connected to the curves on the apparatus with curves have exactly the same properties and dimensions. On the apparatus with curves; the measurements of the depth and width of the curves, the measurements of the depth, width and length of the tapered parts, the measurements of the elevation strips preventing water passage, the measurements of the slopes towards the tapered part can be increased or decreased according to the need and thus the invention can be used in different places, climates and geographies.

[0030] Another purpose of the invention is to provide less load on the roof of the building or the roof of the structure it is on in terms of weight when compared to green roof systems. When the invention is compared to green roof systems, while green roof systems are suitable for the growth of plants with deep roots and long vertical length, the apparatus with curves is not suitable for the growth of plants with deep roots and long vertical length because the depth of the curves of the apparatus with curves is not sufficient for the growth of plants with these features.

[0031] Another purpose of the invention is to ensure that the apparatus with curves on the roofs is easy to install since it can be fixed to the roofs with different and various materials.

[0032] Since it is possible to design the invention for roofs with different slopes depending on the ground, such as low, medium or high slope; it can be designed and produced depending on the slope angle of the roof on which it will be placed. Although the invention is suitable for use on roofs with different slopes depending on the ground, such as low, medium or high slope, it is not considered appropriate for use on terraces and similar flat or very low slope roofs where people spend time walking for social purposes or other reasons. Because it is not considered appropriate for people to walk on the invention, both for people and for the purposes of the invention.

[0033] Since the invention can be designed to be used on roof surfaces of different sizes, it can be designed and produced in different sizes.

[0034] In the preferred application of the invention, it is aimed to make the apparatus with curves that are used to keep some of the rainwater on its surface for the outer surface of the roofs from a non-transparent material, thus preventing the apparatus with curves from showing lens properties in sunny weather and thus preventing it from causing fires with sun rays.

[0035] In the preferred application of the invention, it is aimed to make the apparatus with curves that are used to keep some amount of rainwater on its surface for the outer surface of the roofs from a non-black material, thus preventing the apparatus with curves from overheating in sunny weather and thus causing fires, and also preventing the material of which the apparatus with curves is composed from melting and / or deteriorating its structure.

[0036] In the preferred application of the invention, it is intended that the apparatus with curves that are used to keep some of the rainwater on its surface for the outer surface of the roofs should be made of materials that are not easily broken, do not crack, have some flexibility, and are not water permeable, such as plastic or plastic derivatives.

[0037] In the preferred application of the invention, the material thickness of the curved apparatus can be increased or decreased according to the place of use and need.

[0038] The present invention as explained aims to eliminate the different disadvantages determined in the known state of the art by designing an economical product that is fast, easy to use and maintain with its basic structure and distinctive elements and does not require technical expert support, thus, to spread the practice of keeping some of the rainwater on the apparatus with curves that are used to keep some of the rainwater on its surface for the outer surface of the roofs and to ensure that it evaporates naturally there and finally to reduce the amount of rainwater to be transmitted to stream beds, sewage and similar systems and to reduce negativities such as floods and floods and in addition, it aims to increase the air quality by providing oxygen to the atmosphere and absorbing some of the dust in the air by lichens and similar small and short plants on the apparatus with curves.

[0062] Detailed Description of the Invention

[0063] The subject of the invention essentially consists of the apparatus with curves (2); since it is possible to design the invention at different angles according to the ground for the purpose of using it on roofs with different slopes according to the ground, by adhering to the basic structure and features, the subject of the invention is explained in this detailed explanation only in a way that does not create any limiting effect for a better understanding of the subject.

[0064] The apparatus with curves (2) on the roof surface (1) was designed (Figure 1, Figure 3, Figure 5, Figure 6, Figure 7, Figure 8, Figure 9).

[0065] In order to keep the rainwater on the apparatus with curves (2), a curve (3) has been designed, which is upwards and curved from the top towards the ground, where the rainwater will fill. All the curves (3) with the same name on the apparatus with curves (2) have exactly the same features and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 7, Figure 8, Figure 9, Figure 10). In order to keep the rainwater on the apparatus with curves (2), a curve (3) has been designed, which is upwards and curved from the top towards the ground, where the rainwater will fill. All the curves (3) with the same name on the apparatus with curves (2) have exactly the same features and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 7, Figure 8, Figure 9, Figure 10).

[0066] A tapered part (5) combined with the curve (3) was designed to ensure that rainwater coming from above with surface flow is received from the downward flow direction (11) and transmitted to the curve (3). All the tapered parts (5) with the same name on the apparatus with curves (2) have exactly the same features and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 7, Figure 8, Figure 9, Figure 10).

[0067] The curve of the tapered part (6) which is curved towards the ground from the upper part of the tapered part (5) facing upwards, the tapered part (8) which is the region belonging to the most extreme, i.e. sharpest part of the tapered part (5), the right side (9) where the water will flow by filtering in the tapered part which is the right side of the tapered part (5) close to the curve (3) and the left side (10) where the water will flow by filtering in the tapered part which is the left side of the tapered part (5) close to the curve (3) are designed (Figure 2, Figure 3, Figure 4, Figure 5, Figure 7, Figure 8, Figure 9, Figure 10).

[0068] The curve of the tapered part (6) which is curved from the upper part of the tapered part

[0069] (5) facing upwards towards the ground has been designed in order to ensure that the rainwater coming from the surface flow from the downward flow direction (11) of the rainwater is received and transmitted to the curve (3) via the tapered part (5). The curves

[0070] (6) of all the tapered parts with the same name on the apparatus with curves (2) have exactly the same properties and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 7, Figure 8, Figure 9, Figure 10).

[0071] The pointed part (8) is the region belonging to the most extreme, i.e. sharpest part of the tapered part (5) and the pointed part (8) is designed to be inserted into the curved apparatus (2) to a certain extent in order to receive the rainwater coming from the surface flow from the downward flow direction (11) and to transmit it to the curve (3) via the tapered part (5). All the pointed parts (8) with the same name on the curved apparatus (2) have exactly the same features and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 7, Figure 8, Figure 9, Figure 10).

[0072] In order to ensure that the rainwater coming from above with the surface flow in the direction of the downward flow direction (11) of the rainwater is directed to the pointed part (8), a slope (7) has been designed towards the pointed part (8) combined with the pointed part. All the slopes towards the pointed part (7) with the same name on the curved apparatus (2) have exactly the same characteristics and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 7, Figure 9, Figure 10).

[0073] When the curve (3) is filled with rainwater, due to the elevation differences, the rainwater is directed towards the tapered part (5) connected to the curve (3), and excess water is discharged from the right side (9) where the water will drain and flow from the tapered part, which is the right side of the tapered part (5) close to the curve (3), and from the left side (10) where the water will drain and flow from the tapered part, which is the left side of the tapered part (5) close to the curve (3). The right sides (9) where the water will drain and flow from all the tapered parts of the same name on the curved apparatus (2) have exactly the same properties and dimensions. The left sides (10) where the water will drain and flow from all the tapered parts of the same name on the curved apparatus (2) have exactly the same properties and dimensions (Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 7, Figure 8, Figure 9, Figure 10).

[0074] The curved apparatus (2) is designed as a single piece with curves (3), elevation strips (4) preventing water passage, tapered parts (5) and slopes towards the pointed part (7), making it easy to install on roofs (Figure 1, Figure 2, Figure 3, Figure 4, Figure 7, Figure 8, Figure 9, Figure 10).

[0075] Since it is possible to design the curved apparatus (2) for use on roof surfaces of different sizes, it can be designed and produced in different sizes. The design of the curved apparatus (2) for use on roof surfaces of different sizes has been achieved by increasing the number of curves (3), elevation strip preventing water passage (4), tapered part (5) and slope towards the tapered part (7) as required.

[0076] The measurements of the depth and width of the curves (3) on the apparatus with curves (2); the measurements of the depth, width and length of the tapering parts (5), the measurements of the elevation strips (4) preventing water passage, the measurements of the slopes towards the pointed part (7) can be increased or decreased according to the need, thus enabling the invention to be used in different places, climates and geographies.

[0077] Industrial Application of the Invention

[0078] The apparatus with curves that retains a quantity of rain water on its surface for the exterior surface of roofs that serve the above-mentioned purposes, can be produced and used in any branch of the industry and is applicable to the industry.
