Description

  The present invention relates to an antenna mounting structure, for example, to a technique for attaching a film antenna to a glass surface of a vehicle or the like.

  In the present invention, the “water-insoluble adhesive” is synonymous with an adhesive whose adhesiveness is not weakened by moisture.

  Various techniques for attaching a film antenna to a glass surface of a vehicle have been put to practical use (see, for example, Patent Documents 1 to 3). Prior art (1) By spraying water or neutral detergent water on the adhesive surface of the film antenna, the film antenna can be slipped with a water film at the beginning of the bonding operation, and then the film antenna is temporarily attached. Keep it. Next, after adjusting the position of the film, water and bubbles are removed to the outside of the film using a spatula or the like, and the film antenna is fixed to the glass surface with an adhesive.

  Prior art (2) The adhesive can be used repeatedly by using self-adhesive glue or the like.

  In the prior art (1), the position of the film can be adjusted by interposing a water film, but when removing water and bubbles, the position of the adjusted film is easily shifted, and the film is brought into a predetermined position. It is difficult to apply. Moreover, it is necessary to remove water and bubbles carefully and frequently, and workability is poor.

  In the prior art (2), the appearance is worsened by taking in air when the film is applied. If air is taken in, it is difficult to remove the air.

  An object of the present invention is to provide an antenna mounting structure capable of improving workability and improving appearance.

The present invention is provided with a film antenna, a temporary fixing portion for positioning and temporarily fixing the film antenna to a pasting target,
An antenna mounting structure comprising: a main fixing portion that is provided in another portion of the film antenna excluding the temporary fixing portion, and that permanently fixes the film antenna to a sticking target.

Further, the present invention is a book provided on a film antenna and provided on a temporary fixing portion for positioning with respect to a sticking target and other portions of the film antenna excluding the temporary fixing portion and fixed to the sticking target so as to be relatively movable. A fixing part,
The temporary fixing part is an antenna mounting structure characterized in that the temporary fixing part is temporarily fixed prior to fixing of the main fixing part so as to prohibit movement from the sticking target accompanying relative movement of the main fixing part with respect to the sticking target.

In the present invention, the temporary fixing portion is made of a water-insoluble adhesive.
The main fixing part is made of a water-soluble adhesive.

  Further, the present invention is characterized in that a thermosetting adhesive that adheres by heating is applied to the main fixing portion.

  In addition, the present invention is characterized in that an adhesive layer including a temporary fixing portion and a main fixing portion and a film are multilayered.

  According to the present invention, after the temporary fixing portion is positioned and temporarily fixed to the application target, the main fixing portion excluding the temporary fixing portion is fixed to the application target. The entire film antenna, that is, at least the temporary fixing portion does not move from a predetermined position due to a light load at the time of removing moisture and bubbles (referred to as bubbles) in the main fixing portion. In this state, bubbles or the like interposed between the film antenna and the object to be attached can be easily removed. Even if the main fixing portion moves during the removal of bubbles or the like, the main fixing portion can be easily returned to a desired position with reference to the temporary fixing portion at a predetermined position. Therefore, workability can be improved and the appearance can be improved.

  Moreover, according to this invention, after temporarily fixing a temporary fixing part to the sticking object, this permanent fixing part is fixed to the said sticking object so that relative movement is possible. With the relative movement of the main fixing part, the temporary fixing part prohibits movement from the object to be pasted. Even if the main fixing portion moves undesirably, the main fixing portion can be easily returned to the desired position with reference to the temporary fixing portion at a predetermined position. Therefore, workability can be improved and the appearance can be improved.

  Further, according to the present invention, after temporarily fixing a temporary fixing portion made of a water-insoluble adhesive to an application target such as a glass surface, the main fixing portion made of a water-soluble adhesive is fixed to the application target. Therefore, the temporary fixing portion that is firmly fixed to the main fixing portion does not move undesirably from a predetermined position due to a light load at the time of removing bubbles or the like in the main fixing portion.

  Further, according to the present invention, the temporary fixing portion and the main fixing portion can be attached to the attachment target without using moisture by the thermosetting adhesive. Therefore, the workability can be further improved.

  Further, according to the present invention, the temporary fixing portion and the main fixing portion can be attached to the attachment target by using the photocurable adhesive without using moisture. Therefore, the workability can be further improved.

  Further, according to the present invention, even when the application to the object to be applied has failed, the adhesive layer and the film that have failed can be reused by removing them by one layer. This is advantageous in that the initial adhesive strength can be maintained and the burden on the user can be reduced.
