Description

Automotive sun visor that can be mounted without any vehicle type {Sunvisior of vehicle that installationis possible regardless of vehicle type}

The present invention relates to a sun visor for automobiles, and to provide that can be mounted irrespective of the vehicle type, while preventing the shape deformation during bending by varying the width and thickness of the sun visor while extrusion molding using a soft plastic In order to prevent morphological deformation caused by temperature changes, suitable pigments are used.

In general, the sun visor is attached to both side doors of the car to vent the air in the car while driving, and is used to block outside dust, smoke, or rainwater from entering the car.
Therefore, the sun visor is attached to the top of the door window using a conventional adhesive means or in a special case using a separate fixing means is used, the problem of this is that the appearance of the door is different for each car and the curve rate is different Therefore, the sun visor must be manufactured according to the type of vehicle.
Therefore, in order to apply this to all kinds of vehicles for injection molding, a considerable number of molds are required to be manufactured, and since the vehicle is not sold much, the economical efficiency is low. The disadvantage is that it can not be used.
In addition, for injection molding, as shown in FIG. 8, a runner and a gate are formed to inject a liquid raw material, and molding is performed. Since injection of a long article such as a sun visor requires high pressure, It must be enlarged in size.
In addition, only a small amount can be injected and cooling takes too long, resulting in a very low production efficiency. As a result, the cost rises as well as the price increase.
Due to the nature of rigid plastics, continuous exposure to ultraviolet light causes the hardening and the longer the service life, the easier it is to break even with a small impact, and there is a risk of a safety accident due to the damage of the sun visor. It is short and inconvenient to use.

Therefore, in the present invention, it is possible to be used in a variety of models without distinction of the vehicle by forming a soft plastic so as not to be deformed in the overall form by bending according to the curvature of the vehicle.

For this purpose, it is possible to cut and cut along the length while using extruded soft plastic, and the ratio of width and thickness of the sun visor is designed so that no deformation occurs even when the sun visor is bent. To prevent the bent portion from protruding upwards, and to prevent the change of form due to temperature change, an appropriate pigment is used.

As described above, the present invention can be used according to the curvature and length of the car door, so it can be used for all types of vehicles, and can be easily attached since it is bent and attached to all models by its own elastic force, even when bent upwards. It can be manufactured at low cost by avoiding the protruding phenomenon of lifting, which can reduce the production cost, and can be used for a long time without replacement while maintaining a clean appearance because it is not easily damaged.

Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings. In the following drawings, the same reference numerals are used for the same components.

As shown in FIG. 1, the present invention relates to a sun visor 1 attached to an upper end of an automobile door 100, wherein the sun visor 1 is made of a soft body so that the sun visor can be cut and used to form a horizontal door. Along the upper curved surface of the (100) is to allow the user to be attached to a variety of models while bending the sun visor (1) directly.

At this time, the structure of the sun visor (1) is extended to the mounting table (2) and the lower end of the vertical to be attached to the upper curved surface of the top of the door 100, as shown in Figs. It is made of a blocking film (3) to protrude to form a curved surface, the inner surface (2a) of the mounting table (2) to form an adhesive means (4) is to be attached to the door 100 to be used, at this time The adhesive means 4 is to attach the double-sided tape and then attach the release paper 5 to the back surface thereof to remove the release paper 5 and to attach the sun visor 1.
Therefore, in the state in which the sun visor 1 is attached to the door 100, the foreign matter is prevented from entering the vehicle by the blocking film 3.

At this time, in the present invention, in order to prevent the deformation even in the state attached to the upper curved surface of the upper end of the door 100, the thickness of the cross-sectional area and the upper and lower lengths of the mounting table 2 and the blocking film 3 is the sun visor (1) When the bend along the upper curved surface of the car door 100 is to be made of a thickness and length such that the lower end of the blocking film 3 is not folded, for this purpose, in the present invention, the mounting table 2 and the blocking film ( 3) the ratio of the thickness of 1: 1.5 ± 0.5 and the ratio of the upper and lower lengths of the mounting table (2) and the barrier film (3) is 1: 2 ± 0.5 ratio of the ratio of the door (100) When attached to the upper curved surface of the) will prevent the phenomenon that the bottom of the blocking film (3) is folded while being raised.
If the ratio of the thickness is less than 1: 1, the phenomenon occurs that is folded when bent, and when the ratio is 1: 2 or more, there is a problem that the bending is not made.
In addition, even if the length ratio of up and down is also less than 1: 1.5, there is a problem that the folding occurs when bent, and if it is more than 1: 2.5, there is a problem of falling down.

In addition, the sun visor (1) is the most preferable size for preventing the body from being curved while being curved while being attached to a variety of models, the thickness of the mounting table (2) and the inner surface (2a) of the While the upper and lower lengths α are 12 mm, the vertical length β from the lower end of the inner surface 2a to the lower end of the blocking film 3 is formed at 23 mm, and the blocking film 3 is 5-7. It is desirable to achieve a radius of curvature of 90 ° or less while having a thickness of ㎜.

That is, the thicker the thickness of the mounting table 2 and the blocking film 3, the more difficult the bending of the sun visor 1, the longer the thickness of the mounting table 2 and the blocking film 3, the sun visor 1 Fold occurs when bending).

On the other hand, if the length of the blocking film 3 is too short, the blocking film 3 does not block foreign matters, so that the efficiency of the sun visor 1 is lowered, so that the use of the sun visor 1 becomes unnecessary.

In addition, since the blocking film 3 is protruded in an arc shape, the degree of protruding to the outside of the blocking film should be shorter than the vertical length β of the blocking film so that it is easy to bend on the plane of the sun visor 1.

Therefore, as described above, by setting the optimum ratio that can bend the thickness and length of the mounting table (2) and the blocking film (3) of the sun visor 1, the attachment of the sun visor (1) made of a soft body is easy to form It can be attached without deformation.

In addition, as shown in FIG. 5, the barrier layer 3 may generate a difference in the thickness of its cross-sectional area so that the barrier layer 3 may withstand high pressures such as strong winds without causing deformation during bending of the sun visor 1. To this end, a first end surface (Τ₁) closest to the mounting table (2) and a second end surface (Τ₂) located at the center of the blocking film (3) and the third end of the blocking film (3) for this purpose. The thickness of the first cross-section (Τ₁), the second cross-section (Τ₂) and the third cross-section (Τ₃) in a state divided into a section (Τ₃) to form a curved surface at a ratio of 6: 7: 5, respectively Mounting of the sun visor 1 while the barrier film 3 is further reinforced by the second end face Τ₂ which is subjected to the most pressure, and the thicknesses of the first end face Τ 단 and the third end face Τ₃ of both sides are narrowed. It is easy to bend at the time.

The sun visor 1 may form a horizontal surface 3a inside the blocking film 3 as shown in FIG. 3A, or may have the curved surface 3b inside the blocking film 3 as shown in FIG. 3D. Even when it is formed, it is easy to restore the original shape even when it is lifted by the bent part when it is attached according to the curvature of the upper curved surface of the door 100 according to the vehicle type, so that the shape deformation during bending of the sun visor 1 It will be more prevented from happening.

In addition, when the auxiliary tape 6 having a strong tensile force is attached to the entire inner surface of the barrier film 3, the sun visor 1 is attached along the upper curved surface of the door 100. The bent portion generated when the bent portion is bent by the strong tensile force of the auxiliary tape (6) is to be able to prevent the deformation of the shape as the bending barrier film (3) is returned to its original shape.

At this time, the auxiliary tape (6) is preferably attached to the tape of a material having a high surface tension, as described above, without having to adhere to the entire inner surface of the barrier film 3, as shown in Figure 6 according to the type of door ( Auxiliary tape (6) can be attached only to a part by attaching it in accordance with the curvature of the upper curved surface of 100).

In this case, since the auxiliary tape 6 is partially attached to the position where the bend of the sun visor 1 occurs depending on the vehicle type, the auxiliary tape 6 is to be attached to different positions depending on the vehicle type.
As described above, the sun visor 1 to be molded is manufactured by extrusion molding as described above, so that the sun visor 1 can be cut and used according to a required length, so that the sun visor 1 uses a soft PVC to make the soft body. If the use of only soft PVC as a raw material, the strength of the sun visor (1) is too weak and easily bent or deformation occurs.

Therefore, it is preferable that the composition ratio of the raw material is mixed with 100 ± 50% by weight of soft PVC in 3.5 ± 0.5% by weight.

At this time, the mixing of the raw material is made to uniformly stir the powdered hot water and PVC resin in a stirrer and then cut it into a certain size while extruding it in an extruder (primary molding), the compound is produced in the molding machine It is preferable that the sun visor 1 is extruded (secondary molding) by re-injecting the raw material.

If the compound is used without compounding, the raw materials may not be uniformly mixed and thus may not perform the desired performance.

And the bath is attached to the sun visor (1) to have a certain hardness as a kind of limestone, when the mixing ratio of the bath is less than 3% by weight, there is a problem that deformation occurs in the molded state at a high temperature, in particular soft PVC has difficulty in molding.

On the other hand, when the mixing ratio of the bath is more than 4% by weight, the surface of the burst occurs during the bending of the sun visor (1), in particular due to the natural curing by the ultraviolet rays have a problem of poor durability.

In the high temperature environment, the sun visor 1 is easy to bend, but the hardness is lowered. In the low temperature environment, the sun visor 1 becomes harder to bend instead of increasing the hardness of the sun visor. It is only a problem when attaching, so it can be produced by changing the composition ratio according to the season.

That is, it is preferable that the raw material is mixed by setting the mixing ratio of the bath in a high temperature within a set range in summer, and the raw material is mixed by setting the mixing ratio of a bath in a low range within a set range in winter.
