[0001] A KINETIC FACADE ELEMENT

[0002] Technical Field

[0003] This invention relates to a kinetic facade element that can move by using shape memory material in order to prevent the heating effect of the sun at high temperatures and to benefit from the heating effect of the sun at low temperatures.

[0004] Prior Art

[0005] There are various approaches to the use of shape memory materials in facade systems in projects in the present art. These projects generally aim to provide shading and ventilation on the facade. However, in order to produce the products developed in these projects, a large number of parts and high-cost shape memory materials are required. For this reason, there is a need for a kinetic facade element that allows the use of sun or blocking it according to the ambient temperature by using the optimum amount of shape memory material, which is a low part count and high cost component.

[0006] In the international patent document numbered W02020240433, which is in the state of the art, a dynamic facade system used to control shading is mentioned. The said facade system consists of a block consisting of an outer glass panel, an intermediate frame to which a series of steel cables are fixed, and an inner frame containing an inner glass panel. The mentioned outer glass panel, intermediate frame and inner frame are combined together.

[0007] The said system comprises modules fixed on the mentioned cables. The said modules comprise a first outer structure, the said first outer structure comprises a frame-shaped square base and at least one first wing. The said at least one first wing is movably connected to the said frame-shaped square base by means of a first hinge. The first hinge is made with a shape memory element having a passive configuration. Brief Description of the Invention

[0008] The object of this invention is to create a solution option for sustainability and energy efficiency and to realize a movable facade element that will increase the energy performance of the building without requiring a computerized control system or energy consumption, thanks to the use of shape memory materials.

[0009] Another object of this invention is to realize a kinetic facade element that creates a surface that opens and closes thanks to its movement, thus creating shading in a way that prevents the heating effect that develops depending on the temperature from entering the building.

[0010] Another object of this invention is to realize a kinetic facade element that prevents the heating effect of the sun at high temperatures and allows the use of the heating effect of the sun at low temperatures by making a folding movement of the surface in front of the building facade within the rigid origami principles.

[0016] 1. Kinetic facade element

[0017] 2. First spring

[0018] 3. Second spring

[0019] 4. Rail

[0020] 5. Plate A kinetic facade element (1), which is the subject of the invention, can move thanks to the use of shape memory material in order to prevent the heating effect of the sun at high temperatures and to benefit from the heating effect of the sun at low temperatures, and comprises:

[0021] - at least two first springs (2),

[0022] - at least two second springs with shape memories (3),

[0023] -the first spring (2) at the bottom of the 'll' shaped internal structure, at least one rail (4) extending in a 'V' shape on which the second spring (3) is placed on the first spring (2) and

[0024] - at least one plate (5) having a quadrilateral form with folding strips on it, which can perform a folding movement by bending from the folding strips as a result of the spring action thanks to the connection established with the first and second springs (2, 3) on the rail (4) from the ends of the quadrilateral form.

[0025] The second spring (3) of the same length is placed on the first spring (2) in the kinetic facade element (1) which is the subject of the invention and the hooks at the ends are connected to each other. The first spring (2) can move with the movement of the second spring (3). The first spring (2) is made of steel material.

[0026] The second spring (3) located in the kinetic facade element (1) which is the subject of the invention is placed on the first spring (2), the hooks at the ends are connected with the hooks on the first spring (2) and are selected to be the same length as the first spring (2). The second spring (3) is made of a shape memory material that contracts as the temperature increases and extends as the temperature decreases. In an embodiment of the invention, the second spring (2) may have the ability to move according to the presence or absence of daylight. In a preferred embodiment of the invention, the second spring (3) is a shape memory alloy made of nitinol, an alloy of nickel and titanium.

[0027] The rail (4) in the kinetic facade element (1) which is the subject of the invention is obtained by combining two aluminum parts with a 'U' shaped internal structure with a corner connection piece in a way that extends in a 'V' shape. In another embodiment of the invention, the rail (4) is solid. The rail (4) is mounted to the facade of the building by means of screws passed through the holes under the ends. The hooks of the springs placed on the rail (4) are attached to the holes in the vertical corner connection piece rising at the non-joining ends of its ‘II’ shaped parts, with the first spring (2) at the bottom and the second spring (3) at the top. Thus, the springs (2, 3) are placed on the rail (4).

[0028] The plate (5) in the kinetic facade element (1) which is the subject of the invention has a quadrangular surface form and has folding strips on it. There is a non- stretchable fabric on the fold strips of the plate (5) that allows surface movement, and this fabric acts as a low-cost connecting element. The plate (5) is folded in a way that it has a Miura-Ori rigid origami folding pattern (folding strips) consisting of a small number of identical pieces with a single degree of freedom, which allows a large surface to be folded into a compact form, allowing the surface to remain flat and enabling the entire surface to be set into motion by changing the angle between just two pieces, regardless of how many pieces the surface consists of.

[0029] In an embodiment of the invention, the plate (5) can be folded to have any origami folding pattern with a single degree of freedom. In a preferred embodiment of the invention, the plate (5) is made of aluminum, which is light, resistant to environmental conditions, low cost and easy to use. The plate (5) has a hole on the upper right and left corners, and these holes are attached to the first and second springs (2, 3), and as the temperature increases, the second spring (3) narrows and moves, opening the surface to provide shading on the building facade, and as the temperature decreases, the second spring (3) extends and folds on the building facade, allowing the sun rays to pass into the building and providing heating.

[0030] Industrial Application of the Invention

[0031] A prototype has been developed for the kinetic facade element (1) which is the subject of the invention and the said prototype has been prepared using 4 right- angled trapezoidal aluminum plates, 2 nitinol springs, two steel springs, 4 steel screws, 2 right-angled corner connectors, 1 corner connector, 1 C aluminum profile with a 45 degree cut edge and 1 C aluminum profile with a 135 degree cut edge. In the process of joining these parts, firstly the aluminum C profiles are joined from their 45 degree and 135 degree cut edges to obtain the ‘V’ shaped rail (4). 1 corner connection piece and 2 steel screws are used to join the profiles. Perpendicular corner connection pieces are mounted on both ends of the ‘V’ shaped rail (4). The screws used in the assembly of these pieces are 2 steel screws that are longer than the steel screws attached to the corner connection piece, as they are also used in the connection of the facade element to the building facade. Nitinol springs (4) are mounted by connecting the hooks on the springs to both ends of the rail (4) system produced. At this stage, the holes on the right corner connection piece are used. 2 steel springs (3) are mounted to the rail by connecting them to the hooks of the nitinol springs (4) with the hooks at one end, and the hooks at the other ends are connected to each other. 4 equal, trapezoidal aluminum plates (5) are combined in a way that allows the desired movement of the surface to be created.

[0032] A non-stretchy and durable fabric that can act as a hinge is used during the assembly phase. Holes are opened in the upper two corners of the produced surface, large enough to allow the hooks on the springs (2, 3) to pass through. The surface is connected to the rail (4) system by attaching the hooks to which the nitinol and steel springs (3, 2) are connected to each other, to the holes opened on the plate (5).

[0033] Of the spring pairs placed inside the rail (4), the ones made of shape memory alloy (3) are positioned at the top, and the steel ones (2) are positioned at the bottom. In this way, thanks to the shape memory spring that will narrow after the temperature rises, the plate (5) that will move with it is opened and shading is provided. In the case where the temperature is below the level at which the shape memory alloy is active, the weight of the material forming the plate (5) and the tension in the steel springs (2) act in the opposite direction, causing the plate (5) to become folded. This folded plate (5) allows sunlight and solar radiation to enter.

[0034] It is possible to develop a wide variety of applications for the subject of the invention, "A Kinetic Facade Element (1)", and the invention cannot be limited to the examples described here, but is essentially as stated in the claims.
