As shown in FIG. 2, in the conventional film processing method, first, the skin materials 3 ′ and 3 ″ each having a pattern added to the member 1 ′ and the member 2 ′ are pasted with a vacuum pressure machine (FIG. 2 ( a)), and the members were assembled with screws, claws, etc. (see FIG. 2B) to manufacture a member containing two types of patterns. A completed drawing is shown in FIG.
However, in the above method, the work process is complicated, and the integrity of the two types of handle parting is also poor.
Therefore, the film processing method of the present invention employs a method of using one skin material with two types of patterns and assembling two parts.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows an embodiment of the film processing method according to the present invention. The members 1 and 2 are constructed so that they can be slid by temporarily assembling a general-purpose resin (ABS or the like) formed by injection molding. . Each member 1 and 2 is formed with one or more sets of guide grooves or protrusions on each member to prevent sliding and lateral displacement of the member, and further, there is a gap portion 5. It has a configuration that can maintain this state.
The skin material 3 is obtained by adding two patterns to a film having a thickness of about 0.2 to 0.5 mm such as acrylic or polycarbonate.
As an example of the film processing method, a skin material 3 in which parts 1 and 2 are temporarily assembled and two kinds of patterns (pattern A and pattern B) slightly longer than the skin material 3 of the completed member are added. The skin material 3 is aligned so that the boundary 4 between the two types of handles corresponds to the gap 5 between the temporarily assembled members (see FIG. 1A). And it heats with a heater etc. as needed, it softens, pressurizes a decoration surface with a vacuum pressure machine etc., and decompresses the back side of a decoration surface, The groove | channel 6 provided under the gap | interval part 5 The air escapes from the air, and the skin material 3 corresponding to the gap 5 is sucked downward (see FIG. 1B).
And when the skin material 3 is affixed to the temporarily assembled members 1 and 2, the skin is deformed so as to bend to the anti-skin side by the action of vacuum pressure (see FIG. 1B). Therefore, the boundary portion 4 of the handle is buried in the gap portion 5 by sliding the member 2 so as to eliminate the gap portion 5 of the temporarily assembled member 2 (the member 1 may naturally slide). Then, the state can be maintained by the locking claws, and finally the film processing is completed by finally assembling with screws and claws.

  It can be used for film processing of all types of vehicle members.
