Description

[Technical Field]

[0001] To provide a permanent sun visor that can be used without interfering with all functions including those of the existing sun visor, and can be easily and compactly stored in the existing sun visor when not in use, in relation to a light shielding plate that is newly attached to a genuine sun visor already installed in an automobile. [Background technology]

[0002] Products in this field currently available on the market are attached to the sun visors that come as genuine parts in automobiles by clipping them on. They usually come as a set of two types of transparent plastic plates. They are attached to the exterior of the genuine sun visors to reduce sunlight and UV rays during the day, and to block glare from oncoming vehicle headlights and wet road surfaces at night. However, these conventional auxiliary sunshades have unavoidable issues with their handling, such as the inconvenience of attaching and removing them, the danger of doing so on the road, and where to store them inside the car after removal.

[0003] When using the factory sun visors to block direct sunlight, this auxiliary shade interferes with the use of the factory sun visors and can be visually annoying and cause fatigue. Furthermore, because the auxiliary shade is not functionally integrated with the factory sun visors and is always clipped in within the driver's upper field of vision, whether in use or not, it is an eyesore. It is bulky, makes unpleasant noises, and is prone to falling off, creating problems when removing it while driving and finding a temporary place to store it inside the car. These factors reduce the driver's concentration and sense of security, posing a risk to safe driving. Therefore, it remains unused to a large extent. Summary of the Invention [Problem to be solved by the invention]

[0004] With this method, since there are differences in the size and shape of the pre-installed genuine visors, an auxiliary sunshade plate of a suitable size must be installed. Also, there may be cases where installation using this method is difficult due to differences in the installation form of the genuine visor. Although it is necessary to develop a storage device for such different types of automotive sun visors, the development goal will first be to develop a storage device with the most common form. [Effects of the Invention]

[0005] The installation of this permanent sun visor reduces heat fatigue caused by the external environment while driving, protects against UV rays, blue light, and avoids adverse conditions such as rain and road reflections at night, creating a more desirable driving environment. It will also reduce the sense of inadequacy and frustration caused by the incomplete device described above in

[0003] , and it is believed that permanently stored sun visors will be needed in an era never before seen. DETAILED DESCRIPTION OF THE INVENTION

[0006] Two U-shaped plates (2) are placed and fixed on the upper end, which is the rotating shaft of the existing sun visor (1), and a pair of holders A (5) and B (6) are movably attached to the same axis at both ends of a horizontal bar (4) held by two horizontal bar plates (3) attached to the outer surface of the U-shaped plates so that they can be opened and closed.

[0007] The purpose of attaching the horizontal bar plate (3) to the U-shaped plate (2) is to reduce the impact on the holders AB (5) (6) when opening and closing the existing sun visor (1) and to maintain its independent movement.

[0008] A coil spring (9) is installed at the connection point between the U-shaped plate (2) and the horizontal bar (3), and when the visor (1) is tilted forward, the horizontal bar (3) springs up together with both plates AB (7) and (8). This prevents the plates AB from shifting when the visor (1) is moved, and also separates the loads acting on each other.

[0009] The two holders A (5) are attached to the outside of both ends of the visor (1), and the two coaxial holders B (6) are attached to the inside of both ends of the visor, and each moves independently. (The existing genuine sun visor may be referred to as the visor below.)

[0010] A daylight shield A (7) is slidably mounted on holder A (5), and the upper end of A can move over the lower end of the visor (1). A luminous shield B (8) slides on holder B (6), and is mounted inside both ends of the visor (1), so it cannot move over the visor (1). Daylight plate A (7) can move over luminous plate B (8). (Hereinafter referred to as daylight plate and luminous plate.)

[0011] A doughnut-shaped radial magnet (10) is fitted to the surfaces facing each other on the connecting point at the upper end of holder A (5) and holder B (6) that are adjacent to each other on the left and right. A rotating link (11) is provided in close proximity to each magnet. By utilizing the repulsive force between the radial magnets (10) and the rotary link (11), the two plates AB (7) and (8) can be made to intersect or intersect with each other as surfaces, and the up and down positions of the two plates can be changed.

[0012] A slider AB (12) is movably inscribed in each of holder A (5) and holder B (6). Several wheel-like rollers (13) are fitted at equal intervals inside the slider AB (12) so that they can rotate freely, and a single drive belt (14) is tightly wound around each of the axles of all four rows of rollers.

[0013] The roller (13) has a certain degree of elasticity and friction, allowing it to rotatably contact the inner wall of holder A (5). At the same time, the other end of the roller (13) is in close contact with the side of plate A (7), which is slidably fitted into it. By moving plate A (7) back and forth, holder A (5) and plate A (7) can be moved in opposite directions at equal intervals via the sliding of slider A (12). This helps shorten the holder and improve operability. The same applies to holder B (6) and plate B (8).

[0014] By combining the above

[0013] , when the lower end of plate A (7) or plate B (8) is pulled out and pushed in, both plates can be smoothly extended and retracted beyond the length of each holder via the slider (12). Furthermore, by using these settings and operations, the outer daylight plate A (7) can climb over the existing sun visor (1) and luminous plate B (8), and the stacking order of plates A (7) and B (8) can be changed when using and storing them.
