sun protection

Abstract

Device for protecting large areas against direct sunlight, comprising: two or more approximately T-shaped supports, each having a column and a crossbeam, wherein the lower part of the column of the T-supports extends into the ground, wherein the T-supports are freestanding, self-supporting and spaced apart from each other, and one or more covers, wherein each cover is stretched between two T-supports, wherein each cover is made of material that is at least partially opaque and at least partially permeable to water.

Description

The application concerns freestanding sun protection devices for large areas. Numerous examples of the design, construction and material of sun protection devices are known from the state of the art. Particularly in the area of ​​large umbrellas, which cover 30 square meters or more, conventional freestanding solutions usually feature constructions that require massive base frames and / or employ a fastening technique in which the supporting parts or the cover are fixed and anchored with poles, ropes or cords. The purpose of the application is to offer an improved solution that does not require heavy weights to fix the supporting structure, nor does it include tension cables or cords. Furthermore, sufficient stability should be achieved so that a light to moderate wind load can be absorbed. Finally, the aim is to prevent a water bubble from forming when it rains. This problem is solved by a device according to claim 1. The proposed solution consists of at least two approximately T-shaped supports, each with a column and a crossbeam. The lower end of the column extends sufficiently deep into the ground. A cover is stretched between the crossbeams of the T-beams and fixed along the crossbeams, e.g. using a clamping technique or eyelets. The accompanying figure shows a sketch of one embodiment of the sunshade device according to the invention. It depicts two T-beams and a cover stretched between the crossbeams. The columns of the T-beams project into the ground. The T-beams are anchored in the ground by their columns, making them self-supporting and able to bear the load of the cover stretched between the crossbeams. Bracing the structure, consisting of the T-beams and cover, with additional ropes or cords is unnecessary. Heavy weights for securing the structure are also not required. The preferably rectangular cover is stretched between the crossbeams of the T-beams, creating a shaded area on the ground underneath. Suitable materials for T-beams include wood, metal, plastic or mixed constructions. Suitable materials for the cover include at least partially opaque fabrics or mesh. Partially water-permeable fabrics or mesh prevent water from pooling during rain and reduce stress on the structure. One advantage of this design is that the ground area around the T-beams and in the area of ​​the shaded area remains free of obstacles, anchors, ropes, and cords. This eliminates tripping hazards. The typical use of this sun protection device is to create a large shaded area of ​​approximately 30 to 60 square meters, where a large number of people can be present. The typical height of the column of the T-beams is approximately 3 to 5 m. The typical width of the crossbeam of the T-beams corresponds approximately to the width of the cover and is around 3 to 7m. The typical spacing of the T-beams corresponds approximately to the length of the cover stretched between them and is about 8 to 10m. The typical hole depth in which the lower part of the column is located is approximately 60 to 100 cm. However, these specifications should not be interpreted as restrictive. With appropriate dimensioning and material selection of T-beams and covers, larger dimensions and shaded areas are also achievable. If required, additional T-beams and covers can be added to the structure shown in the figure to form a chain of covers. For example, three T-beams can support two covers stretched between them. For structural reasons, the covers are preferably rectangular in shape. However, other quadrilateral shapes, such as trapezoids or parallelograms, are also possible. The crossbeam is typically mounted at a right angle to the column. However, it can also be at a different angle in order to align the cover as perpendicular as possible to the incoming sun rays and to maximize the shaded area on the ground. The heights of the columns of the T-beams can vary in order to align the cover as perpendicular as possible to the incident sun rays and to maximize the shaded area created on the ground. The cover may have a hole in the middle to allow water to drain out and prevent water bubbles from forming. Reference symbol list 1 Column 2 Crossbeam 3 Cover 4 Hole in the ground 5 Ground level
