Description

Solar-sensitive electric tarp {SUNLIGHT SENSITIZED TYPE ELECTROMOTION TARP}

The present invention relates to a solar-sensitive electric tarp, and more specifically, it is possible to create an optimal shade space by automatically varying (available / expand and contract) the plane of the light-shielding film in response to changes in solar altitude and sunlight irradiation angle. It relates to a solar-sensitive electric tarp.

Economic growth and the development of science and technology, including information technology, highlight the importance of free time in everyday life as well as the overall improvement of living standards, and are important in determining the quality of human life. It is recognized as a factor.

In particular, with the introduction of the five-day work week, the demand for leisure on weekends has increased significantly, and the form of leisure is very diverse, and as a result, the camping population enjoys camping with family, lovers and friends. It was found that in the past year, it exceeded 5 million.

Here, camping (camping / camping) refers to leisure activities that lead to temporary outdoor living in tents or temporarily built cottages, and escapes the frustrating daily life and nature away from the crowded city. It can be said that I feel a lot of charm from the viewpoint of enjoying.

On the other hand, in order to enjoy the best healing at a camping site, an optimal camping environment is required. In addition, it is very important in terms of UV protection to create a space that can avoid strong sunlight.

In this regard, the installation of a tarp, which is also called a shading membrane as a tool to serve as a roof during camping, can cover the sun and create a cozy and shady space to avoid sunlight.

However, since the tarp's light-shielding film has a standard, it is difficult to prepare an optimal shade space corresponding to a change in solar altitude and a corresponding sunlight irradiation angle. Accordingly, the user has a hassle of having to move a chair or mat every time the shaded range is changed.

In order to solve this problem, through the Republic of Korea Registered Utility Model No. 20-0272755, while having a wide field of view, it is possible to appropriately change the angle of the shade according to the location of the sun, and a simple structure that can be installed in various forms It has been disclosed.

1 is a perspective view showing a configuration relationship of a shading membrane according to the prior art, wherein the shading membrane of the prior art is rectangular and has a width and length ratio of 1: 2 or more, and the poles 920 are fitted at 5 locations on both sides of the left and right sides. A tent paper (910) capable of refracting into four stages based on the fitting ball by forming a fitting ball at a predetermined interval; A plurality of poles 920 capable of supporting the tent 910; A plurality of fixing strings 930 respectively connected to the fitting holes and corresponding positions; And a plurality of packs 940 for fixing the fixing string 930 to the ground.

In addition, the central portion 912 of the tent 910 is supported by a pole 920 to maintain a roof shape, and both wing portions 913 extending from the central portion 912 are horizontally spread, and the tent All the fixing strings 930 provided on the paper 910 are configured to be fixed to the ground.

According to the prior art, according to the configuration of the both wing portions 913 extending from the central portion 912 of the tent 910, it is possible to accommodate a large number of people in the form of a tent, while ensuring a wide field of view Depending on the position, the angle of the shade film can be changed appropriately so that the shade is always formed inside the shade film, and the structure is simple, so it is easy to install and dismantle, and it is strong against the wind by being securely fixed to the ground by the fixing strap 30. There are advantages.

However, although it is possible to vary the shading area such as expanding or narrowing the range of shading by folding or unfolding the both wing portions 913, there has been a hassle that the user must directly perform the corresponding work process.

In the end, the initial installation ensures that the optimum shade space is prepared for the sun altitude and sunlight irradiation angle, but there is no need to move the camping equipment (chair, etc.) according to the fluctuation of the shade and the shade as described above without user intervention. There is an urgent need for Raff's R & D, where the function of space provision is automated.
