Description

  The present invention relates to a sunshade disposed in a vehicle interior, and more particularly to a sunshade having a function of adsorbing and decomposing gaseous harmful substances (eg, formaldehyde).

As the toxicity of formaldehyde becomes a problem, its removal has become an urgent issue in various fields, and automobiles are no exception, and various means for removing formaldehyde from the interior of automobiles are provided. Therefore, Patent Document 1 described later discloses an automobile interior material including a formaldehyde absorbing sheet. That is, this patent document 1 is composed of a base material reinforced with a reinforcing sheet, a skin material, and a formaldehyde-absorbing sheet interposed between the base material and the skin material, for example, an automobile used as a door trim. Disclose interior materials for automobiles. One side of the formaldehyde absorbing sheet is bonded to the base material with an adhesive. As the skin material, a breathable material is selected, and the other side of the formaldehyde-absorbing sheet adsorbs and decomposes formaldehyde (emitted from another interior material) in the passenger compartment to purify the air in the passenger compartment. It is supposed to do.
JP 2000-62543 A (see FIG. 3)

  However, in the above-mentioned automotive interior material, since the adhesive contains formaldehyde and other gaseous harmful substances, this significantly impedes the function of the formaldehyde-absorbing sheet. It is virtually impossible to effectively adsorb and decompose formaldehyde in the room.

Therefore, the present invention has been made in view of the above problems, and has the function of adsorbing and decomposing gaseous harmful substances in the passenger compartment without degrading the function of adsorbing and decomposing gaseous harmful substances such as formaldehyde. It is an object to provide a sunshade comprising:

In order to solve the above-mentioned problems, the technical means taken in claim 1 is a sunshade comprising a panel arranged along a curved surface on the vehicle interior side of a glass of a vehicle. Are connected to each other in a non-adhesive manner, the reflective material facing the glass , a ventilation member exposed to the vehicle interior, and interposed between the reflective member and the ventilation member, the vehicle interior And a purification member that adsorbs and decomposes the gaseous harmful substances, and the purification member is a bellows-like or corrugated sheet.

In this case , it is desirable that the panel is formed in a folding screen and can be folded.

Further , the upper end portion and the lower end portion of the panel are preferably locked to the sun visor and the front instrument panel, respectively . Furthermore, the panel may be suspended from one or both of the sun visor and the rearview mirror .

  According to the first aspect of the present invention, since the purification member for adsorbing and decomposing formaldehyde and other gaseous harmful substances is provided in the sunshade, no special installation space is required. In addition, the purification member that adsorbs and decomposes formaldehyde and other gaseous harmful substances is connected to the reflective material and the ventilation member, which are the outer surfaces of the sunshade, in a non-adhesive manner. It is free from the contained adhesive and its effectiveness is not diminished.

In addition, the purification member is provided in the form of a sheet. Therefore, since the purification member is biased downward due to gravity in the gap between the reflective material and the ventilation member, or the force to expand the gap between the reflection material and the ventilation member does not work, the purification member is placed inside the sunshade with a simple configuration. Can be provided. Moreover, since it is a sheet | seat, since the thickness of a purification | cleaning member can be made thin, the thickness of a sunshade can be made thin. As a result, the weight can be reduced.

Moreover, since the purification member is a bellows-like or corrugated sheet, the area of the air and the sheet (purification member) is increased as compared with a flat shape, and the adsorption / decomposition ability of the purification member can be improved. Furthermore, the passage of the air that has passed through the ventilation member is formed on the reflective material side that does not have a ventilation hole due to the bending of the sheet. Can be improved.

According to invention of Claim 2 , since the panel is formed in the screen-like aspect and can be folded , it is convenient for storage.

According to invention of Claim 3 , since the upper end part and lower end part of a panel are each latched by the sun visor and the front instrument panel, it can hold | maintain stably at the time of use.

According to the invention of claim 4 , since the panel is suspended from either or both of the sun visor and the rearview mirror, it is not necessary to insert the panel between the windshield and the sun visor, Can be used.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, in a room CP of the vehicle V, a sunshade 10 mainly composed of the panel 20 is disposed along the curved surface of the windshield FG. That is, the upper end portion and the lower end portion of the panel 20 constituting the main body of the sunshade 10 are locked to the sun visor and the front instrument panel, respectively, so that the panel 20 follows the curved surface on the indoor side of the windshield FG. In this manner, the vehicle V is disposed in the room CP. This sunshade 10 blocks the irradiation of the direct sunlight to the room CP of the vehicle V, and prevents an abnormal increase in the temperature of the room CP and sunburn / deformation of the interior member.

  As shown in FIG. 2, the outer shape of the panel 20 is a pleated shape or a folding screen as a whole. Of course, the outer shape of the panel 20 may be substantially flat as a whole.

  As shown in FIG. 3, the panel 20 is interposed between the reflective material 22 facing the windshield FG, the ventilation member 24 exposed to the room CP, and the reflective material 22 and the ventilation member 24, and formsaldehyde. It comprises a purification member 26 that adsorbs and disassembles and a frame-like clip 28 that crimps and fixes the outer edges of these three members. Thus, using the clip, the reflector 22 facing the windshield FG, the ventilation member 24 exposed to the room CP, and the reflector 22 and the ventilation member 24 are interposed, and adsorbs and decomposes formaldehyde. Since the panel 20 is configured by connecting the purifying member 26 to each other, it is free from an adhesive containing more or less formaldehyde and other gaseous harmful substances, and the effectiveness of the purifying member 26 is not diminished. In addition, since the sunshade 10 is configured mainly with such a panel 20, the purification member that adsorbs and decomposes formaldehyde in the air is freed from the trouble of providing a special installation space.

  In addition, if the crease | fold 30 is formed in the panel 20 comprised in this way, as shown in FIG. 1, it can fold.

  The reflector 22 facing the windshield FG is made of aluminum / PET material, reflects sunlight rays passing through the windshield FG, and causes an abnormal increase in indoor CP temperature and sunburn / deformation of interior members. To prevent.

  The ventilation member 24 exposed to the room CP is formed of a nonwoven fabric, a net or other air-permeable fibers, and the air in the room CP can directly contact the purification member 26 that adsorbs and decomposes formaldehyde.

  As the purification member 26 for adsorbing and decomposing formaldehyde, a sheet holding a porous material carrying amino acids woven in a bellows shape or a corrugated shape is employed. Due to the bending, the area in the width direction increases compared to the case where the purification member 26 is configured in a flat shape. In addition, a large number of passages extending in the vertical direction are also formed on the front side of the sheet (that is, the windshield FG side) by bending. Thus, the area in contact with the air that has passed through the ventilation member 24 can be increased, and the ability to adsorb and decompose formaldehyde can be improved. In addition, when the purification member 26 is formed in a flat shape, there is a merit that the thickness of the panel 20 can be reduced, and it is not necessarily rejected.

  As described above, the purification member 26 that adsorbs and decomposes formaldehyde is a sheet holding a porous body carrying amino acids woven in an accordion-like or corrugated-like form. , Paper is adopted. The porous body is at least one of activated carbon and viscosity mineral (including sepiolite). The amino acid is at least one of glycine, alanine, lysine, cysteine, phenylalign, serine, arginine, and hydroxylysine.

  In addition to the embodiments described above, the following modifications are also desirable.

A perforation is applied in place of the fold line 30 described above, thereby making it easier to bend and realizing easy storage by folding.

The panel 20 may be configured to be small and may be suspended from one or both of the sun visor 40 and the rearview mirror 50, or may be attached to the sun visor 40 as shown in FIG. .

-You may install along rear glass or side glass.

-It may be installed directly on the glass using a suction cup.
