この考案は自動車のドアーのような、閉断面形
状物の内部に塗布剤を塗布するための、塗布ノズ
ルに関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a coating nozzle for applying a coating agent to the inside of a closed cross-sectional object such as an automobile door.

つた。(Prior Art) When applying rust preventive oil to the inner surface 8 of a closed cross-sectional object having a space inside, such as an automobile door, conventionally, as shown in FIG.
A hose 1 with a coating nozzle attached to the tip thereof was inserted through an opening 7 as small as possible for inserting the coating nozzle, and the coating was applied while moving the hose 1. (Refer to Utility Model Application Publication No. 55-9223) In this case, due to the elastic repulsive force of the flexible hose 1,
Since the tip of the coating nozzle contacts one inner surface 8 of the object 6 to be coated, the inner surface 8 on the contacting side comes very close to the discharge port of the coating nozzle, so that the coating material is sufficiently scattered. However, there were areas where a large amount of coating was applied, and areas where it was not coated or where a small amount of coating was applied, resulting in the disadvantage that uniform coating was not achieved.

る。(Purpose of the invention) In order to eliminate the drawbacks of the conventional products as described above, this invention achieves uniform application by configuring the tip of the application nozzle so that it does not touch the inner surface and maintains an appropriate distance. It was designed so that it could be carried out.

ルである。(Structure of the invention) This invention for achieving the above-mentioned purpose is such that the flexible hose 1 is inserted through the opening 7 provided in the object 6 having a closed cross section while being attached to the tip of the flexible hose 1.
In the coating nozzle for spraying a coating agent onto the inner surface 8 of the object to be coated, a spring 5 extending in the axial direction of the nozzle body 2 is provided on the outer periphery of the nozzle body 2 with one end fixed and the other end loosely fitted, This is a coating nozzle in which the spring 5 is swollen in its natural state so that the nozzle body 2 maintains a predetermined distance from the inner surface 8 of the object to be coated.
(実施例)
以下この考案の実施例を、図面にもとづいて詳
細説明する。(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

2が取り付けられており、ノズル先端部3の外周
に吐出口4が設けられている。 Fig. 1 is a partially cutaway side view showing an embodiment of this invention, and Fig. 2 is a view of Fig. 1 viewed from the tip side. A nozzle body 2 made of hard plastic is attached, and a discharge port 4 is provided on the outer periphery of the nozzle tip 3.
5はスプリングで、外向に湾曲した複数本(図

2の外周に等間隔に配列して、その両端をリング
5a,5bに固定し、後端側のリング5aはノズ
ル本体2の外周に固定し、先端側のリング5bは
ノズル本体2の外周に遊嵌されている。 5 is a spring, and a plurality of outwardly curved linear bodies (six pieces are shown in the figure) are arranged at equal intervals around the outer circumference of the nozzle body 2, and both ends of the springs are fixed to rings 5a and 5b. The ring 5a on the rear end side is fixed to the outer periphery of the nozzle body 2, and the ring 5b on the tip side is loosely fitted on the outer periphery of the nozzle body 2.
これを使用するに当つて、第4図に示すように

ル先端部3は内面8に接せず、常に間隔を保つこ
とができるので、吐出口4から噴射される塗布剤
は内面8に満遍なく塗布できるものである。 When using this, as shown in FIG. 4, when inserting the spring 5 into the opening 7 provided in the object 6 having a closed cross-section, the spring 5 should be adjusted to the diameter shown by the phantom line in FIG. When the spring 5 enters the inside of the closed section, it elastically returns to its original position and expands in the radial direction, and the outside of the expanded spring 5 comes into contact with the inner surface 8, which is the surface to be coated. Since the nozzle tip 3 does not come into contact with the inner surface 8 and can always maintain a distance, the coating agent sprayed from the discharge port 4 can be evenly applied to the inner surface 8.
塗布を完了して塗布ノズルを開口部7から引き
出すときは、後端のリング5aがノズル本体2に
固定されているので、スプリング5は開口部7に
よつて膨らみが絞られ、第1図仮想線で示すよう
に細くなつて引き抜かれるものである。 When coating is completed and the coating nozzle is pulled out from the opening 7, the ring 5a at the rear end is fixed to the nozzle body 2, so the bulge of the spring 5 is narrowed by the opening 7, and as shown in FIG. It becomes thinner and is pulled out as shown by the line.
以上の説明において、閉断面形状の被塗物例と
して自動車のドアーを挙げたが、自動車の関係で
もドアー以外、例えばサイドシルにも利用できる
ものであり、また自動車関係以外のものであてつ
も、閉断面形状の内部に塗布剤を塗布する場合は
同様に利用できることはいうまでもない。 In the above explanation, an automobile door was mentioned as an example of a closed cross-sectional object to be coated, but it can also be used for things other than automobiles, such as side sills, and it can also be used for things other than automobiles, even when closed. Needless to say, it can be used in the same way when applying a coating agent inside the cross-sectional shape.

る。(Effects of the invention) As explained above, according to the invention, by providing the coating nozzle with a simple and inexpensive spring that expands in its natural state and can contract in the radial direction, the injection port of the coating nozzle and the coated material are It is possible to maintain a predetermined distance from the inner surface of the object, and it is possible to uniformly and evenly apply paint, anti-corrosion oil, etc. to the inside of the object with a closed cross-section. Since the diameter of the spring can be reduced and the spring can be passed through the spring, there is no need for a large diameter opening, which has the effect of minimizing the decrease in rigidity of the object to be coated due to the provision of the opening. It is something.
