EXAMPLES Examples 1 to 6 of the first to sixth sticking methods according to the present invention will be described below with reference to the drawings. In addition,
A polyolefin film was used as the protect film.

(Example 1) An example of the first attaching method (hereinafter referred to as Example 1) will be described.

FIG. 1 is a plan view showing a typical example of a fastener T used in the sticking method of the first embodiment, and shows a state in which the release paper is partially peeled off. 2 shows the fastener T of FIG.
It is an enlarged front view which looked at from the arrow A direction.

In both figures, reference numeral 1 designates FIG. 4, FIG. 5 and FIG.
Car hood 4 and boot lid 5 shown in Figure 6
It is a cap to put on. This cap 1 is obtained by cutting a so-called tarpaulin sheet in which a woven cloth is sandwiched with an ethylene-vinyl acetate copolymer, and obtained by cutting two right-angled triangular sections a and b of the same size on each other to form a short side. It has a structure in which the portion 1a is fused, and the long side portion 1b side is an opening. The sections a and b are the hood 4 of the cap 1.
And, in the state of being attached to the trunk lid 5, they come to the front side and the back side, respectively. The section a is the front sheet according to the present invention, and the section b is the back sheet according to the present invention.

Reference numeral 2 is an adhesive layer provided on the surface of the section a of the cap 1, and 3 is a release paper attached to the adhesive layer 2.

Next, an example of how to attach the fastener T to the hood 4 and the trunk lid 5 and an example of how to attach the protect film using the fastener T to the hood 4 and the trunk lid 5 are shown in FIGS. This will be described step by step with reference to FIG.

(1) The fastener T is attached to the projected corner portion 6 of the hood 4 and the trunk lid 5 with the release paper 3 side facing up (front side).

(2) The release paper 3 of the fastener T is released.

(3) As shown in FIG. 7, the protect film 7 attached to the hood 4 is cut sufficiently larger than the hood 4, and the margin 7a around the periphery of the hood 4 is wrapped around the hood 4.
Is provided. Similarly, as shown in FIG. 8, the protect film 8 attached to the trunk lid 5 is cut sufficiently larger than the lid 5, and a margin 8a for winding the back side of the trunk lid 5 is provided at the peripheral edge portion.

(4) The protect films 7 and 8 are spread on the hood 4 and the trunk lid 5, respectively, and attached in a stretched state to the exposed adhesive layer 2.

(5) The winding allowances 7a and 8a of the protect films 7 and 8 are wound around the back side of the hood 4 and the trunk lid 5.

(6) Finally, the hood 4 and the trunk lid 5 are closed, and the winding allowances 7a and 8a are set as shown in FIGS.
As shown in FIG.

In FIG. 9, 10 is a cowl top, 11 is a cowl top grill, and 12 is a rear panel in FIG.

The protective film 7 once attached,
The peeling of No. 8 is performed by the reverse process to the above.

As described above, if the fastener T is used, the hood 4 of the protect films 7 and 8 and the trunk lid 5 will be described.
It is easy to stick to and does not require special skill. Further, the adhered protect films 7 and 8 can be easily peeled off, and the phenomenon that the adhesive agent remains attached to the surface of the hood or the like, which has occurred conventionally, is eliminated.

Further, as described above, when the fastener T is used, the adhered protect films 7, 8 and the hood 4 and the trunk lid 5 are in a state of substantially evenly contacting each other over the entire surface, which is extremely extreme. No uneven sticking occurs.
As a result, even if the protect films 7 and 8 are left attached for a long period of time, uneven gloss is unlikely to occur on the surfaces of the hood 4 and the trunk lid 5.

Further, when the fastener T is used, the protect films 7 and 8 are attached to the surface side of the fastener. Therefore, the protective film 7,
Even when the cord 8 is in the extended state, the contracting force at that time does not act on the folded portions of the hood 4 and the trunk lid 5 on the back side. Therefore, there is no possibility that the same portion will be torn at the tip of the corner portion 6 of the hood 4 or the trunk lid 5.

In the above fastener T, the tarpaulin sheets were used for the sections a and b, but sheets of polyethylene, polypropylene or the like may be used, and the short side portions 1 of the sections a and b may be used.
Although a is fixed by fusing, it may be sewn or bonded. The fastener T is an example in which the apex angle of the cap 1 is a right angle, but may be slightly acute or obtuse depending on the shape of the projected corner of the panel to be covered. For example, a portion having a slightly acute angle, such as a projecting corner portion on the rear side of the hood, preferably has such an acute angle.

Further, the cap 1 of the fastener T has a structure in which the pieces a and b of the same size are fixed.
Like the fastener T _{1 in} FIG. 3, the surface section a may be longer than the back section b in the depth direction B of the cap 1. Alternatively, although not shown, the reverse may be performed.
In this way, the cap 1 can be easily attached to the hood 4 or the trunk lid 5 on the projecting corner portion 6. In FIG. 3, the same parts as those in FIG. 1 are designated by the same reference numerals.

In the fastener T, an ethylene-vinyl acetate copolymer tarpaulin sheet was used as the front side sheet and the back side sheet, but other than this, for example, an integrally molded product of the front side sheet and the back side sheet is also used. can do.

(Example 2) An example of the second attaching method (hereinafter referred to as Example 2) will be described.

The second embodiment is a method of attaching a protective film to the hood 4 and the trunk lid 5 by using the fastener T used in the first embodiment and the elastic clip C described later.

That is, in comparison with Example 1, Example 2 is different from Example 1 in that, in Example 1, the protect films 7 and 8 wound around the back side of the hood 4 and the trunk lid 5.
It is a pasting method in which an elastic clip C is fitted from above, as illustrated in FIG. 13, before closing the hood 4 and the trunk lid 5. As shown in FIGS. 12 and 13, the fitting position is the side edge 5a between the projected corner 6 and the projected corner 6 of the hood 4 and the trunk lid 5. Example 2 is
Different from the first embodiment.

As shown in FIG. 11, the elastic clip C is made of rubber and has a U-shaped cross section. The lower tongue piece 14 is longer than the upper tongue piece 13 in order to facilitate the fitting to the hood 4 or the trunk lid 5.

The distance between the upper and lower tongue pieces 13 and 14 is determined by the side edge portion 5a of the hood 4 or the trunk lid 5 (FIG. 13).
Is formed to be slightly smaller than the thickness of. Therefore, the clip C elastically clamps the side edge portion 5a when fitted to the side edge portion 5a.

As described above, when the elastic clip C is used, the peripheral portions of the protect films 7 and 8 can be stored more easily. Other functions and effects are the same as those of the first embodiment.

(Example 3) An example of the third pasting method (hereinafter referred to as Example 3) will be described. Example 3 is shown in FIG.
The protective clip is attached to the hood 4 and the trunk lid 5 using the elastic clip C ₁ shown in FIG.

The elastic clip C ₁ is made of rubber, has a U-shaped cross-section and is L-shaped in plan view. Although the same L-shape, the elastic clip C ₁ shown in FIG. 14 is an example, and in reality, it has an acute-angled shape or an obtuse-angled shape in accordance with the planar shapes of the projected corner 6 of the hood 4 and the trunk lid 5. Items are available.

In the elastic clip C ₁ , the lower tongue piece 16 is longer than the upper tongue piece 15 so that the hood 4 and the trunk lid 5 can be easily fitted to the projecting corner portion 6.

The distance between the upper and lower tongue pieces 15 and 16 is equal to that of the hood 4.
It is formed to be slightly smaller than the thickness of the projecting corner portion 6 (FIGS. 9 and 10) of the trunk lid 5. Therefore, when the elastic clip C ₁ is fitted into the projecting corner portion 6, the resilient clip C ₁ has the projecting corner portion 6
Can be elastically clamped.

Next, the procedure for attaching the protect film using the elastic clip C ₁ to the hood 4 and the trunk lid 5 will be described.

Since the mounting procedure is basically the same between the case of the hood 4 and the case of the trunk lid 5, here, referring to FIG. 15 for the case of mounting to the hood 4 shown in FIG. 15, It will be explained step by step.

(1) The protect film 7 is covered on the hood 4, and the peripheral edge thereof, that is, the winding allowance 7a provided in advance is wound around the back side of the hood 4.

(2) An elastic clip C ₁ is fitted on the projected corner of the hood 4 from above the wound protective film.

(3) The hood 4 is closed and the winding allowance 7a
Is sandwiched between a weather strip (not shown) which is a receiving portion of the hood 4.

(2) The other release paper of the attached double-sided adhesive tape R is peeled off.

(3) A protect film 21 is attached to the other exposed adhesive layer 20.

Protect film 21 once attached
The peeling is performed by the reverse process to the above.

As described above, when the double-sided adhesive tape R is used, the protection film 21 can be easily attached to the roof 22, and no special skill is required. Further, the attached protective film 21 can be easily peeled off, and the phenomenon that the tacky adhesive remains attached to the surface of the roof 22 which has occurred conventionally is eliminated.

Further, as described above, the double-sided adhesive tape R
If the protective film 21 and the roof 22 are used, the protective film 21 and the roof 22 are in contact with each other almost uniformly,
Extreme sticking unevenness will not occur. Therefore, even if the protective film 21 is left attached for a long period of time, uneven gloss does not occur on the roof surface.

(Example 6) An example of the sixth sticking method (hereinafter referred to as Example 6) will be described.

Example 6 is a method of attaching the protective film 21 to the roof 22 by using the double-sided adhesive tape R used in Example 5 and sandwiching it with a door 23 described later.
