[Industrial applications]

 This invention relates to a fastener for a protective film that covers the hood, trunk lid, door, etc. of an automobile to protect its painted surface.

[0002]

[Prior art]

 As-produced vehicles, the gloss of the vehicle body coating surface deteriorates during transportation and storage as it is due to acid rain, bird droppings, dust, etc. Therefore, in order to prevent this, conventionally, a film of polyolefin or the like having an adhesive layer on the back surface is attached to the front surface of the hood, trunk lid, roof, etc. of the automobile after production.

However, this film and the sticking method thereof have the following problems.

(1) Since it is attached to the hood, trunk lid, etc. by the adhesive layer, if the stretched state of the film and the timing of attachment are a little misaligned, wrinkles will form in the attached film and It may float from the surface of the hood. If this wrinkle is left for a long period of time, the wrinkle portion remains as a gloss-reduced portion, causing uneven gloss on the surface such as hood.

(2) When attaching the film, it is necessary to expel the air remaining between the surface of the hood, the trunk lid and the like and the film. For this reason, the sticking work is difficult and requires considerable skill before the sticking is successful.

(3) When the film is peeled off when exposed to hot weather or extremely low temperature for a long period of time, the adhesive agent remains on the surface of the hood, the trunk lid or the like. Therefore, the peeling work of the film may be difficult.

The present invention has been made in order to solve such conventional problems. (1) A protective film can be attached to the surface of a hood or the like without causing uneven gloss, 2) A protective film can be easily and easily attached to the surface of a hood, etc. without requiring special skill. (3) A protective film for automobiles that can be easily peeled off. The purpose is to provide ingredients.

[Means for Solving the Problems]

 The fastener of the automobile protective film provided by this invention is a substantially triangular cap composed of a substantially triangular front side sheet and a back side sheet, an adhesive layer provided on the surface of the front side sheet, and this adhesive layer. It is composed of a release paper attached to the agent layer.

As the front side sheet and the back side sheet, for example, an ethylene-vinyl acetate copolymer tarpaulin sheet can be used.

One of the front side sheet and the back side sheet may be formed longer than the other in the depth direction of the cap.

The fastener of the present invention is mainly used by being attached to the corners of the automobile hood, trunk lid, door and the like.

[0012]

[Action]

 (1) The fastener of the present invention can be attached to the protruding corner of the hood, trunk lid, door, etc. with the release paper side facing up.

The protective film should be peeled off from the release paper of the fastener attached to the protruding corner, then spread on the hood, trunk lid, door, etc., and attached to the adhesive layer exposed in the stretched state. You can

The folding margin portion of the peripheral edge of the film prepared in advance is folded back along the edges of the hood, the trunk lid, the door, etc., and sandwiched between the weather strip and the hood, the trunk lid. It can be attached to the edge of doors, etc.

As described above, according to the fastener of the present invention, the protection film can be easily and easily attached to the hood, the trunk, the door, or the like. The applied film can be easily peeled off by the reverse process, and no adhesive remains on the painted surface.

(2) In the pasted state, the protect film, the hood, the trunk lid, the door, and the like are in a substantially even contact state over the entire surface, and no sticking unevenness occurs.

Therefore, even if the protect film is left attached for a long period of time, uneven gloss does not occur on the surface of the hood or the like.

[0018]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a plan view of the fastener T of the embodiment, showing a state in which the release paper is partially peeled off. FIG. 2 is an enlarged front view of the fastener T of FIG. 1 seen from the direction of arrow A.

In both figures, reference numeral 1 denotes a cap which is put on the projecting corner portion 6 of the hood 4 and the trunk lid 5 of the automobile shown in FIGS. 4, 5 and 6. This cap 1 is obtained by cutting a so-called tarpaulin sheet sandwiching a woven fabric with an ethylene-vinyl acetate copolymer, and stacking two right-angled triangular sections a and b of the same size, It has a structure in which the side portion 1a is fused, and the long side portion 1b side is an opening. The sections a and b come to the front side and the back side of the cap 1 when the cap 1 is worn on the hood 4 and the trunk lid 5. 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 FIG. ~ It will be described step by step with reference to FIG.

(1) The fastener T is put on the projected corner portion 6 of the hood 4 and the trunk lid 5 with the release paper 3 side facing upward (front surface) 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 a folding margin 7 a is provided on the back side of the hood 4. 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 folding margin 8a is provided on the back side thereof.

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

(5) The folding margins 7a and 8a of the protect films 7 and 8 are folded back along the edges of the hood 4 and the trunk lid 5, and as shown in FIG. 9 and FIG. Sandwich it between. In FIG. 9, 10 is a cowl top, 11 is a cowl top grill, and 12 is a rear panel in FIG.

The protect films 7 and 8 that have been once attached can be easily peeled off by a process reverse to the above.

As described above, if the fastener T of the embodiment is used, the protection films 7 and 8 can be easily attached to the hood 4 and the trunk lid 5, and no special skill is required. Further, the attached protective 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 of the embodiment is used, the pasted protective films 7, 8 and the hood 4 and the trunk lid 5 are in almost the same contact state over the entire surface. Therefore, extreme sticking unevenness does not occur. As a result, even if the protect films 7 and 8 are left attached for a long period of time, the unevenness of gloss hardly occurs on the surfaces of the hood 4 and the trunk lid 5.

Further, when the fastener T of the embodiment is used, the protect films 7 and 8 are attached to the surface side of the fastener. For this reason, even when the protect films 7 and 8 are in the stretched 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 embodiment, the tarpaulin sheet was used for the sections a and b, but a sheet of polyethylene, polypropylene or the like may be used, and the short sides 1a of the sections a and b are fixed by fusion. However, it may be stitched or glued. Further, the above embodiment is an example in which the apex angle of the cap 1 is a right angle, but it may be slightly acute or obtuse depending on the shape of the projected corner of the panel to be covered. For example, it is desirable to make such an acute-angled portion in a portion having a slightly acute-angled shape, such as a projected portion on the rear side of the hood.

Further, the cap 1 of the above-described embodiment has a structure in which the pieces a and b of the same size are fixed, but like the fastener T _{1 in} FIG. It may be longer than 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 5 on the projecting corner 6. In FIG. 3, the same parts as those in FIG. 1 are designated by the same reference numerals.

Further, in the above-mentioned examples, the tarpaulin sheet of ethylene-vinyl acetate copolymer was used as the front side sheet and the back side sheet, but in addition to this, for example, an integrally molded product of the front side sheet and the back side sheet is also used. You can do it.

Further, in the above-mentioned embodiment, the case where the fastener T is used for the hood and the trunk lid of the automobile has been described, but it can also be used for covering the door of the automobile with a protective film, for example.
