Description

  The present invention relates to a contact sheet used for defrosting a windshield of an automobile.

As a sheet, tool, or cover for preventing frost from adhering to the windshield of an automobile, for example, as described in “Equipment for preventing dew / frost” described in JP-A-8-118964, JP-A-8-197959 “Front glass defrosting prevention sheet”, “Front glass defrosting sheet” described in JP-A No. 11-34673, and “Frost and snow cover for automobile front and rear glass” disclosed in Japanese Utility Model Laid-Open No. 7-18951 Hereinafter, “Conventional Example 1”, “Conventional Example 2”, “Conventional Example 3”, and “Conventional Example 4” are proposed).
Conventional example 1 is made of a vinyl sheet that is one size larger than the windshield of an automobile, and has bar-like magnets embedded along the edges on the upper and lower sides of this sheet. The use of this seat fixes it to the roof and bonnet parts of the car to prevent dew and frost from adhering to the windshield.
Conventional example 2 has a suction cup attached to four corners of the back surface of a vinyl or rubber sheet having a size covering a windshield of an automobile and an edge between them. This sheet is used by fixing it to the front surface of the windshield of an automobile via a suction cup so that frost does not adhere to the windshield.
Conventional Example 3 is a vinyl sheet in which a sheet body is formed in a substantially rectangular shape with cloth, and a suction disk is attached in the vicinity of the upper side of the central part in the longitudinal direction, and suction disks with strings are provided on both sides. . To use this sheet, attach the suction plate to the center upper part of the front of the windshield of the car, then pull one of the strapped suction plates into the car from the door and fasten it to the inside or body of the windshield, and the other to the front. The windshield is defrosted by fastening it to the inside of the glass and attaching the sheet to the windshield.
Conventional Example 4 is composed of cloth or vinyl sheet having a size larger than that of the windshield and rear glass of an automobile, and a plurality of magnets are embedded at intervals on the outer periphery of the sheet. Remove frost and snow.
JP-A-8-118964 JP-A-8-197959 JP 11-34673 A Japanese Utility Model Publication No. 7-18951

In the conventional example 2 and the conventional example 3 in which the suction cup (or suction cup) is used, the suction cup does not necessarily have a sufficient suction force as a sheet mounting means for use in a harsh natural environment in a cold region. Since it is necessary to secure the size of the suction cup to secure the force, a gap is opened between the seat and the windshield by the size of the suction cup, and it is easy for wind to enter this gap. There was a problem that the sheet was easily peeled off.
In the conventional example 1 and the conventional example 4 using the magnet (or magnet), the magnetic force is used. However, like the conventional example 2 and the conventional example 3, there is a problem that the magnet is easily peeled off by a strong wind.
In Conventional Example 1 to Conventional Example 4, the suction cup (adsorption disk) or the magnet (magnet) cannot be easily mounted on the sheet, so it takes time to manufacture the sheet.
An object of the present invention is to provide a contact sheet that can be easily and reliably attached and is easy to manufacture.

A first feature of the present invention is provided with a sheet main body and a belt-shaped adsorbing sheet fixed to the back surface of the sheet main body, and the adsorbing sheet has a plurality of minimal concave portions on the side facing the adherend side. It has a sucker layer that is formed, and the sheet body can be in close contact with the adherend through the sucker layer of the suction sheet.
The second feature of the present invention is that the first feature is provided, and the suction sheet is disposed on the entire circumference (including almost the entire circumference) of the back surface of the sheet body.
According to a third aspect of the present invention, the first feature is provided, and the suction sheet is disposed on the entire outer periphery (including substantially the entire periphery) of the back surface of the sheet main body. It is arranged so as to cross.
A fourth feature of the present invention is that the first, second, or third feature is provided, and the sheet body has linear materials arranged in a grid pattern.
A fifth feature of the present invention is that any one of the first to fourth features is provided, and the seat body is formed of a cold-resistant member.
A sixth feature of the present invention is that any one of the first to fifth features is provided, and the seat body is formed in a size that can cover all or a main part of the adherend. .
A seventh feature of the present invention is that any one of the first to sixth features is provided, and the adherend is a windshield of an automobile.
According to an eighth aspect of the present invention, the seat body includes any one of the first to sixth features, and the seat body is formed of a member capable of providing a blindfold function. It is effective as a blindfold sheet for openings such as doors and windows in houses.
A ninth feature of the present invention is any one of the first to sixth features, wherein the adherend is a windshield of an automobile, and the seat body has a dew condensation prevention sheet secured to the back surface thereof. There is a strip-shaped suction sheet having the same structure as the suction sheet that can be sucked onto the windshield on the back surface of the condensation prevention sheet, and the adhesion sheet is frost or snow on the windshield in a cold region. Or it is effective as a sheet for dew protection.
A tenth feature of the present invention is any one of the second to sixth features, wherein the adherend is a windshield of an automobile, and the seat body is the back surface of the space surrounded by the suction sheet. An anti-condensation sheet is fixed inside, and a belt-like adsorbing sheet having the same configuration as the adsorbing sheet that can be adsorbed to the windshield is adhered to the back surface of the anti-condensation sheet. Is effective as a sheet for frost, snow or dew on the windshield in cold regions.
The eleventh feature of the present invention includes the ninth or tenth feature, and the adsorption sheet of the dew condensation prevention sheet is disposed on the entire circumference (including almost the whole circumference) of the back surface for preventing condensation. Therefore, the contact sheet is effective as a sheet for frost, snow or dew on the windshield in a cold region.

  According to this invention, since it can be adhered to the adherend via the adsorption sheet, the position of the adhesion sheet can be maintained in a stable state, and the problem of being easily peeled off by strong winds can be solved. In addition, reliable attachment is possible, and easy attachment and detachment makes it easy to handle and easy to manufacture.

  The contact sheet 10 shown in FIGS. 1 to 4 includes a sheet main body 11 and a belt-like suction sheet 12 fixed to a plurality of locations on the back surface of the sheet main body.

1 and 2, the sheet main body 11 is made of a transparent plastic sheet such as vinyl, and the thickness is preferably about 0.2 to 1.0 mm because it has flexibility, but is not necessarily limited to this range. As will be described later, when the contact sheet 10 is used as a frost protection sheet, a cold-resistant member is used as a material.
The seat main body 11 has a shape corresponding to the shape of the windshield G1 of the automobile, which is an adherend, and has a size that covers the windshield, that is, a size that covers the whole or the main part of the windshield. In the example shown in FIG. 1, it is trapezoidal and covers the main part.

As shown in FIGS. 1 and 2, the suction sheet 12 includes a first suction sheet 12 a disposed on the entire outer periphery of the back surface of the sheet body 11 and a second suction sheet 12 b disposed in the center portion. .
The first suction sheet 12a is fixed along the edge of the entire outer periphery of the back surface of the sheet body 11 using strip-shaped suction sheet pieces 12a1, 12a2, 12a3, 12a4, 12a5, 12a6, 12a7, 12a8. A fixing band is formed. A double-sided adhesive tape or the like is used as a fixing means for each of the suction sheet pieces 12a1 to 12a8.
The second suction sheet 12b is formed in a band shape, and is arranged on the back surface of the sheet body 11 so as to cross the center portion thereof in the vertical direction. The second suction sheet 12b has a role of reinforcing the fixing force of the sheet body 11 by the first suction sheet 12a.
The suction sheet 12 is a film-like plastic sheet, and as shown in FIG. 5, the upper side is a sucker layer 121 having a plurality of extremely small recesses 121 a. This upper side is the side facing the windshield G1 (FIG. 1). The thickness of the suction sheet 12 is desirably increased on the one hand in order to maintain the suction force by the suction cup layer 121. On the other hand, it is necessary to make the gap between the adhesion sheet 10 and the windshield G1 as narrow as possible. About 2mm is good. But the thickness of the adsorption sheet 12 is not restricted to said range. In this example, the suction sheet 12 is made by cutting “diafit” (trade name) sold by Tokuo Co., Ltd. into a strip shape.

Next, a method for using the adhesive sheet 10 will be described.
When the contact sheet 10 is used as a defrosting sheet for the windshield G1 of an automobile, as shown in FIG. 1, after the back surface of the contact sheet is made to correspond to the front surface of the windshield, the attachment position of the contact sheet is determined. When the back surface is pressed against the front surface of the windshield, the suction sheet 12 (the first suction sheet 12a and the second suction sheet 12b) is deformed with the suction layer 121 (FIG. 5) being brought into contact with the front surface through the recess 121a. It is adsorbed and the contact sheet is held in close contact with the windshield.
As a result, since the contact sheet 10 covers the main part of the front surface of the windshield G1 of the automobile, frost is prevented from adhering to the windshield.
To remove the adhesion sheet 10 from the windshield G1 of the automobile, the adhesion sheet 10 is peeled off by pulling it strongly behind it (in front of the windshield).

  According to the example shown in FIG. 1, the adhesion sheet 10 that can be adhered to the windshield G <b> 1 of the automobile that is the adherend uses the adsorption sheet 12 that is thin and has the sucker layer 121 as the adhesion means. For this reason, since the clearance gap between the adhesion sheet 10 and the windshield G1 can be made very narrow, the subject that an adhesion sheet peels off with a strong wind etc. can be solved, and the said adsorption sheet 12 is attached to the adhesion sheet 10. Since it is attached by sticking, no special attachment means such as drilling is required, so that it can be attached easily and reliably, and the attachment and detachment of the contact sheet is easy because it uses the adsorption force. In addition, since the contact sheet 10 and the windshield G1 have a narrow gap, the impression of the contact sheet is integrated with the windshield, so that the image of the attachment state of the contact sheet is improved, and at night It is presumed that the presence of the adhesive sheet is difficult to confirm and is effective in preventing theft.

Other forms of the adhesive sheet 10 will be described with reference to FIGS. 6, 7 and 8 to 11.
In the contact sheet 20 shown in FIG. 6, the feature of the configuration is that the linear material 21 a is used to enhance cold resistance and durability, and other configurations are the same as those of the contact sheet 10.
Therefore, the features of the contact sheet 20 will be described below, but a detailed description of the configuration common to the contact sheet 10 will be omitted.
A linear material 21a made of plastic is embedded in the sheet main body 21 of the contact sheet 20, and in the example shown in FIG. 6, the linear material 21a is arranged in a lattice shape on the entire surface of the sheet main body. The sheet body 21 is formed by laminating film sheets, and the linear material 21a is sealed while being sandwiched between both film sheets.
The first suction sheet 22a and the second suction sheet 22b of the suction sheet 22 correspond to the first suction sheet 12a and the second suction sheet 12b of the suction sheet 12, respectively.
The method of using the adhesive sheet 20 and the effects thereof are the same as those of the adhesive sheet 10.

In the adhesive sheet 30 shown in FIG. 7, the characteristics of the configuration are in use and shape, and other configurations are substantially the same as those of the adhesive sheet 10.
Therefore, the features of the contact sheet 30 will be described below, but a detailed description of the configuration common to the contact sheet 10 will be omitted.
The adhesion sheet 30 is an ultraviolet reflecting sheet that is a material that is not capable of transmitting ultraviolet rays. For this purpose, the sheet main body 31 includes an ultraviolet reflecting layer. The application of the adhesive sheet 30 is attached to the inside of the door glass G2 on the front side of the automobile as shown by the chain line in FIG. 7 to suppress the irradiation of ultraviolet rays contained in sunlight in the vehicle.
The sheet main body 31, the first suction sheet 32 a and the second suction sheet 32 b of the suction sheet 32, and the suction sheet pieces 32 a 1, 32 a 2, 32 a 3, 32 a 4, 32 a 5, 32 a 6, 32 a 7, 32 a 8 are the first suction sheet 12 a of the suction sheet 12, It corresponds to the second suction sheet 12b and the suction sheet pieces 12a1, 12a2, 12a3, 12a4, 12a5, 12a6, 12a7, 12a8, respectively.
The adhesive sheet 30 is used by bringing the adhesive sheet into the automobile, making the back surface adsorption sheet 32 correspond to the inside of the door glass G2, and pressing the back surface against the inner surface of the door glass. The suction sheet 32a and the second suction sheet 32b have their suction cup layers (not shown) in contact with the inner surface and are in close contact with each other through a recess (not shown), and the contact sheet is held by the door glass.
As for the effect of the adhesive sheet 30, a stable attachment state can be maintained similarly to the adhesive sheet 10, and the attachment / detachment thereof is easy.
When the contact sheet 30 is used, since the contact sheet 30 has a very thin structure, the adsorption force may be attenuated over time. According to the experimental example, it is necessary to replace with a new one after about 3 to 4 months.

The contact sheet 40 shown in FIGS. 8 and 9 is characterized in that a dew condensation prevention sheet 45 is fixed to the back surface, and the other configuration is substantially the same as that of the contact sheet 10.
Hereinafter, although the feature of the contact sheet 40 will be described below, a detailed description of the configuration common to the contact sheet 10 is omitted.
In order to prevent the occurrence of condensation on the windshield G1 of the automobile, a condensation prevention sheet 45 is fixed to the back surface of the contact sheet 40. The anti-condensation sheet 45 is made of, for example, a plastic sheet such as vinyl, and is disposed on the back surface of the contact sheet 40 and in a space surrounded by the first suction sheet 42a. In the example shown in FIGS. 8 to 10, the rectangular dew condensation prevention sheet 45 is formed on the suction sheet pieces 42 a 1, 42 a 2, 42 a 3, 42 a 4, 42 a 5 and the second one on both sides of the second suction sheet 42 b (left side in FIG. 8). It is located in the space surrounded by the suction sheet 42b, and on the other (right side), the space is surrounded by the suction sheet pieces 42a1, 42a5, 42a6, 42a7, 42a8 and the second suction sheet 42b.
Each dew condensation prevention sheet 45 is fixed to the entire circumference of the outer periphery of the back surface along the edge with a belt-like suction sheet 46 using a fixing means such as a double-sided adhesive tape (FIG. 10). According to the example shown in FIG. 10, the suction sheet 46 includes suction sheet pieces 46 a 1, 46 a 2, 46 a 3, 46 a 4, and these suction pieces are arranged corresponding to the respective sides of the dew condensation prevention sheets 45. .
The suction sheet 46 (suction sheet pieces 46a1, 46a2, 46a3, 46a4) is a first suction sheet 42a (suction sheet pieces 42a1, 42a2, 42a3, 42a4, 42a5, 42a6, 42a7, 42a8) and a second of the suction sheet 42. The configuration is the same as that of the suction sheet 42b.
The sheet main body 41, the first adsorption sheet 42a and the second adsorption sheet 42b of the adsorption sheet 42, and the adsorption sheet pieces 42a1, 42a2, 42a3, 42a4, 42a5, 42a6, 42a7, 42a8 are the sheet main body 11, the first adsorption sheet 12a and It corresponds to the second suction sheet 12b and the suction sheet pieces 12a1, 12a2, 12a3, 12a4, 12a5, 12a6, 12a7, 12a8 of the suction sheet 12, respectively.
The dew condensation prevention sheet 45 shown in FIGS. 9 and 11 is provided with a plurality of partition walls 45a at equal intervals from the upper side to the lower side, and each partition wall 45a is formed from the left end of FIG. 10 of the dew condensation prevention sheet. It reaches the right end. A hollow portion 45b is formed in the dew condensation prevention sheet 45 in the horizontal direction (perpendicular to the plane of FIG. 9) by each partition wall 45a. The heat insulation function of the sheet 45 for preventing condensation is enhanced by a plurality of hollow portions 45b extending in the width direction (vertical direction in FIG. 11).

In order to adsorb the adhesion sheet 40 having the above configuration to the front surface of the windshield G1 shown in FIG. 9, the condensation prevention sheet 45 of the adhesion sheet 40 and the windshield G1 are opposed to each other, and then this condensation prevention sheet is first used. Is brought into contact with the front surface of the windshield, and when the front surface of the dew condensation prevention sheet is pushed toward the front surface, the dew condensation prevention sheet is sucked through the suction sheet 46 and covers the main part of the windshield. It will be. Next, when the front surface of the outer peripheral portion of the adhesion sheet 40 is pushed in the direction of the arrow in FIG. 9, the first adsorption sheet 42a of the adsorption sheet 42 comes into contact with the front surface of the windshield, and is eventually adsorbed. When pushed, the second suction sheet 42b of the suction sheet 42 comes into contact with the front surface of the windshield and is finally sucked. As a result, the adhesion sheet 40 is adsorbed and fixed to the front surface of the windshield G1 by the first and second adsorption sheets 42a and 42b and by the adsorption sheet 46 on the dew condensation prevention sheet 45 side.
According to the contact sheet 40 shown in FIG. 9, the condensation prevention sheet 45 is fixed so as to cover and contact the main part of the front surface of the windshield G1, so that the occurrence of condensation on the front surface is effectively prevented. Further, as the adsorbing means, the first and second adsorbing sheets 42a and 42b are adsorbed first, and the adsorbing sheet 46 is adsorbed using the dew condensation preventing sheet 46. Adhesion of the adhesive sheet with respect to the surface is enhanced, and there is an advantage that it is not easily peeled off by a strong wind.

  As another example of fixing the dew condensation prevention sheet 45 in the space surrounded by the adsorption sheet 42 of the adhesion sheet 40, the adhesion sheet shown in FIG. Although two sheets 45 are used, when such a second suction sheet is not attached, one sheet for preventing condensation is placed in the space surrounded by the first suction sheet 42a. Thus, the substantially entire surface of the windshield G1 may be covered.

The adhesion sheets 10, 20, 30, and 40 can add an ultraviolet ray prevention function or a dew condensation prevention function in addition to the original functions such as snow and frost removal. In addition to these functions, an adherend, for example, an automobile. It can be used as a front window, a rear door, a door of a house, a store, etc., or a blindfold of a window glass. When used as a blindfold, an opaque member is used as the material of the sheet main bodies 11, 21, 31, 41, and a configuration according to the purpose is required, such as processing into a shape corresponding to the adherend.
The adhering positions of the adsorbing sheets 12, 22, 32, and 42 with respect to the adhesive sheets 10, 20, 30, and 40 are not limited to the illustrated example, and may be partially attached. In the example shown in FIG. 1, in the contact sheet 10, the suction sheet pieces 12 a 2, 12 a 4, 12 a 6, and 12 a 8 are pasted only at the four corners and fixed at four points, or the suction sheet pieces 12 a 1 corresponding to the four sides. , 12a3, 12a5, 12a7 only, and 4 points are held, or in the contact sheet 30 shown in FIG. 7, adsorbing sheet pieces 32a2, 32a4, 32a6, 32a8 are stuck only at the four corners and held at 4 points. Alternatively, only the suction sheet pieces 32a1, 32a3, 32a5, and 32a7 may be attached and fixed at four points corresponding to the four sides. However, as shown in the drawing, if the adhesion position of each adhesion sheet is the entire circumference of the outer periphery, the adhesion sheet can be stably held, and the adhesion sheet is pasted at this position and the position where the adhesion sheet is traversed. As a result, the stability of holding the adhesive sheet is further improved.
