Resin window and method for producing same
View Patent ↗A resin window capable of preventing breakage of defogger wires, and a method for producing the same. The resin window includes a plate-like resin glass extending from one end side to the other end side and having a curved portion formed thereon in the extending direction of the resin glass, and a film disposed so as to follow the shape of the resin glass and having a defogger wire extending in the extending direction of the resin glass. When seen in the direction normal to the resin glass, the defogger wire has a wave-shaped portion in at least a portion at a position corresponding to the curved portion.
1. A method for producing a resin window, comprising:
printing a conductive paste to form a defogger wire on a flat film;
stretching the film with the conductive paste printed thereon so as to form a curved portion; and
forming a resin glass integrated with the film with the curved portion formed thereon,
wherein in the printing, a wave-shaped conductive paste is printed on the film so as to extend in a direction in which the film is to be stretched in the stretching.
2. The method for producing the resin window according to claim 1 , wherein the wave-shaped conductive paste is in a triangular wave shape.
3. The method for producing the resin window according to claim 1 , wherein when a pair of curved portions are formed on opposite end sides of the film in the stretching, in the printing, the wave-shaped conductive paste is printed on the film at positions where the pair of curved portions are to be formed, and a linear conductive paste is printed on the film at another position.
4. The method for producing the resin window according to claim 3 , wherein the wave-shaped conductive paste is attenuated gradually toward the linear conductive paste.
5. The method for producing the resin window according to claim 1 , wherein in the printing, a plurality of conductive pastes are arranged in a direction orthogonal to a direction in which the film is to be stretched in the stretching, such that phases of the adjacent conductive pastes are shifted with respect to each other, and are then printed.
