Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a sunshade, and particularly to a sunshade that is detachably installed on the inside of a vehicle as a light shielding plate for a sunroof.

"Prior art" Conventionally, as shown in Figs. 3 and 4,
This type of sunshade 1 is, for example, one that is attached to an opening 6 formed on the inside of the vehicle interior, such as a roof head lining 5, facing a flat sunroof section 4 formed on the ceiling section 2 of the vehicle interior. Are known. This sunshade 1 usually consists of a synthetic resin plate 1 _a that is integrally molded, and a synthetic resin facing material 1 _b that is attached to the front and back sides of this single plate 1 _a . , is also formed in a flat plate shape corresponding to the flat sunroof part 4.

Referring to FIG. 4, an outline of the sunshade mounting structure constructed as described above will be explained. for example,
The sunshade 1 attached to the opening 6 has one end 9 _a facing the opposite opening 6 _.
It is removably locked by a pair of catchers 7, 7 (see Fig _. 3) which are provided at _a suitable distance from each other. It is removably locked to the other end side 6 _b of the opposing opening 6 via a rotary claw 8 .

Note that the rotating claw 8 is rotated at an angle of about 90°, for example, so that the other end side 6 _b of the opening 6 is rotated.
In this case, the sunshade 1 is supported in the opening 6 at two points on one end side _9a and at one point on the other end side _9b . It is attached so that it can be attached and detached.

Conventionally, in the case of the sunshade 1 that is attached in this way, in order to prevent light leakage, the sunshade 1 is
It was necessary to maintain the dimensional accuracy of the outer circumference to a certain degree.

``Problem that the invention seeks to solve'' However, since Sunshade 1 is shaped like a flat single plate and is made of synthetic resin, it is difficult to solve the problem. ,
For example, if a product is left exposed to high-temperature direct sunlight for a long period of time, it may warp or twist due to thermal deformation. In this case, although it is attached as a light shielding plate of the sunroof portion 4, light leakage occurs and wrinkles are formed even in the covering material, causing problems in terms of light shielding and appearance.

Furthermore, as shown in FIG. 5, some types of vehicles are equipped with a sunroof section 4' extending from the cabin ceiling section 2' to the cabin side wall section 3'.
Such a sunroof portion 4' is gently bent to correspond to the vehicle corner formed by the vehicle interior ceiling portion 2' and the side wall portion 3'.

Therefore, the opening 6' and the sunshade 1' provided opposite to the sunroof part 4' need to be formed in accordance with such a shape, and a bent part is formed in a part of the sunshade 1'. 10
will be formed.

In this case, compared to the conventional method in which a flat sunshade is simply molded in one piece, the bending part 10 must be newly taken into account when setting the dimensions of the sunshade periphery and injection molding, and there may be dimensional errors or This will result in molding errors. This means that
In the sunshade 1', light leakage and poor appearance were caused due to factors different from those in the above case.

In addition, in terms of light leakage caused by thermal deformation (waving), this deformation does not only affect the sunshade 1' side, but also prevents the roof head lining 5 from separating from the cabin ceiling 2' and the cabin side wall 3'. This can also occur on the opening trim (grommet) 15 side, which is stuck in place. Therefore, the bent portion 1
In such a sunshade 1' including 0, it is necessary to take light shielding measures that take into account the deformation of the opening trim 15 side as well as the above-mentioned error.

In order to eliminate these drawbacks, methods have been proposed such as burying steel material within the sunshade or attaching reinforcing plates by riveting, etc., but these methods increase the number of steps and costs. Therefore, it is not practical.

``Purpose of the invention'' Therefore, the main purpose of this invention is to absorb some of the warping and twisting due to dimensional or molding errors, thermal deformation, prevent light leakage caused by these, and improve appearance. Our goal is to provide affordable sunshields that work well.

"Means for Solving the Problems" In order to achieve the above purpose, the main means adopted by this invention consists of a core member and facing materials attached to both sides of the core member, facing the sunroof. In a sunshade that is removably attached to an opening formed on the inside of a vehicle in order to block light from a sunroof, the covering material protrudes from the peripheral edge of the core member and is itself flexible. The portions of the facing material that protrude from the peripheral edge of the core member are fitted together and attached to the opening, and the protruding portion conforms to the shape of the peripheral edge of the opening. It is a point formed by superimposing them closely along the same direction.

``Function'' Even if dimensional errors, molding errors, warping, or twisting occur on the sunshade side and/or the periphery of the opening, the protruding portion of the covering material will, for example, cover the entire periphery of the opening. Since they overlap with each other with good elasticity, some of the above-mentioned errors and deformations are absorbed, and the occurrence of gaps caused by this can be suppressed.

"Effects of the Invention" According to this invention, future light leakage can be reliably prevented and blocked regardless of whether the sunshade is flat or bent.

In addition, it is possible to achieve a simple structure and low cost, and also in terms of appearance in the vehicle interior.
This can be prevented from being damaged.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

Embodiment FIG. 1 is a partially sectional perspective view of a sunshade according to an embodiment of the invention, and FIG. 2 is a schematic longitudinal sectional view showing the sunshade in FIG. 1 attached to an opening. Note that the following example is only one specific example of this invention, and the technical scope of this invention is not limited by this example. Further, the same reference numerals will be used to describe elements common to the conventional sunshade, roof head lining, etc. shown in FIG.

In FIG. 1, the sunshade 1'' is approximately rectangular in plan view (arrow view A) and bent at a gentle angle in side view (arrow view B). As can be seen from FIG. 2, 1'' faces the sunroof section 4' provided from the cabin ceiling section 2' to the cabin side wall section 3', similar to the conventional sunshade shown in FIG. This is the type that is installed.

Next, as can be seen from Fig. 1, the Sunshade 1'' is attached to a core plate _1a ' which is integrally molded from a material such as synthetic resin, and to both sides of this core plate _1a '. It consists of a front facing material 1 _b ′ and a back facing material 1 _b ″. Of these, sheet-like members made of relatively flexible and elastic thermoplastic synthetic resin materials are selected for both the front and back coverings 1 _b ′ and 1 _b ″.

When the front and back covering materials 1 _b ′ and 1 _b ″ are attached to each side of the sunshade 1 ″, for example, the entire periphery of each of them overlaps the entire periphery of the core plate 1 _a. The size is set so that it protrudes from the circumference by a certain width. Therefore, the sunshade 1'' has a protrusion 11 of a constant width formed by pasting together the protruding parts of the front and back covering materials _1b ' and _1b '' over the entire circumference of the sunshade 1''. ing. That is, one end side edge 9 sandwiching the bent portion 10
_a ′, the other end side 9 _b ′, and the side edges 12 _a and 12 _b that are bent due to the bent portion 10 .

In addition, this sunshade 1'' is also provided with a rotating pawl 8 (see Fig. 2) near the other end side _9b ' in order to achieve the intended purpose, as in the case of the conventional sunshade. There is.

As can be seen from FIG. 2, the length of the protrusion 11, that is, the constant width dimension, is determined by the inner peripheral edge of the opening 6', that is, the roof head lining, when the sunshade 1'' is attached to the opening 6'. In addition, in a preferred embodiment, the protruding portions 11 of the front and back covering materials 1 _b ′ and 1 _{b ″ are set such that at least a part thereof is overlapped with the inner side of the front and back covering materials 1 b ′ and 1 b} ″. For example, they are joined by high frequency thermocompression bonding. This causes a thermal change in the protrusion 11, giving it appropriate elasticity and rigidity (flexibility). In other words, the surface of the protruding portion 11 is brought into close contact with the inner shape of the roof head lining 5 due to its appropriate elasticity, so that dimensional errors and thermal deformation are absorbed, and the protruding portion is provided with appropriate rigidity. 11 to the roof head lining 5 is improved.

In the above embodiments, the case where the protrusion is formed by pasting together the protruding parts of both the front and back covering materials has been described. However, in some cases, the protrusion may be formed by only the protruding portion of either the front or back covering material. In addition, although this embodiment does not mention any quantitative restrictions regarding the case where the protrusion is overlapped with the roof head lining, even if the protrusion is in contact with the roof head lining, it is equivalent to the overlapping state. shall be. Furthermore, the covering material has been explained using a material selected from thermoplastic synthetic resin materials. However, materials other than synthetic resin materials may be used as long as they have appropriate elasticity and flexibility.
