BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealer applicator for applying a sealant to a back hem of a hood or a trunk lid of a vehicle body.

[0002]

2. Description of the Related Art It is necessary to apply a sealant for rust prevention to the hem of a vehicle body and a hemming portion on the back surface of a trunk lid. As shown in FIG.
Using a sealer agent applicator as shown in (2), that is, an applicator provided with a flat nozzle b and a guide piece c parallel to the tip of the grip portion a, the worker opens the trunk lid or the bonnet A, and With the applicator positioned toward the hemming portion from the back surface, the guide piece c is applied to the edge of the bonnet A, and the applicator is sealed while moving while being inclined in the sealing direction.

However, in such a coating method, the posture of the worker becomes unnatural. Therefore, even though the guide piece c can be moved along the edge of the bonnet A or the like, the nozzle b cannot be moved. However, since the angle and the nozzle b and the hemming portion cannot be always kept constant, there has been a problem that the sealer cannot be applied accurately and uniformly.

[0004]

[Problem to be solved by the present invention] The present invention has been made in view of such a problem.
It is an object of the present invention to provide a new sealer applicator capable of applying a sealer agent to a backside hemming portion of a hood or a trunk lid accurately and easily.

[0005]

Means for Solving the Problems That is, the present invention provides a sealer applicator for achieving such a problem.
A substantially hook-shaped nozzle body is attached to the tip of the grip portion, and a slit-shaped sealer discharge port that opens toward the grip portion side is provided in the hook-shaped bent portion, and a predetermined sealer coating is provided between the nozzle and the sealer discharge port. By providing a guide member which is in contact with the upper surface of the object to be coated with a gap capable of forming a film and is substantially parallel to the sealer discharge port, the worker can seal the upper surface of the object to the back surface hemming portion from the top. It can be applied uniformly with the agent.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 and 2 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a rod-shaped applicator main body forming a grip portion, and a hook-shaped nozzle body 3 bent into a long L shape communicates with a sealer supply flow path 2 in the main body 1 at the tip. Installed.

In the nozzle body 3, a long shaft portion 3a extending from the main body 1 is bent in a "H" shape so as to make the work of the operator easier, and a tip of the long shaft portion 3a has
The nozzle portion 3b is bent in a hook shape in a direction substantially perpendicular to the surface occupied by the "L" shaped long axis portion 3a.

A slit-shaped sealer discharge port 4 is formed in the nozzle portion 3b at a distance D from the base end to the sealer application portion, that is, at a distal end thereof at a distance from the back surface hemming portion. When the sealer discharge port 4 is positioned on the grip portion side, that is, as shown in FIG. 2, when the applicator main body 1 is moved while being inclined at a predetermined angle θ, the discharge port 4 When the applicator 1 is moved at a certain angle θ from above the bonnet A while the long axis portion 3a is in contact with the edge of the bonnet A by being positioned upward so as to exactly face each other, It is configured such that the sealer agent can be applied to the back surface hemming portion B with a constant film thickness.

On the other hand, reference numeral 5 in the figure denotes a guide roller for applying the sealer with a constant film thickness. It is pivotally supported by the bracket 6 and is opposed to the sealer discharge port 4, and is mounted so as to form a gap δ corresponding to the coating thickness of the sealer agent between the sealer discharge port 4 and the sealer discharge port 4. Reference numeral 7 in the figure indicates a supply hose for the sealant.

Therefore, in order to apply the sealing agent S to the back surface hemming portion B of the bonnet A of the vehicle body W using the applicator body 1 thus configured, as shown in FIG. The applicator main body 1 is applied while supporting the nozzle body 3 in a slightly floating state, and bringing the nozzle body 3 into contact with the edge from the upper surface.

That is, as shown in FIG. 1, when this portion is brought into contact with the long axis portion 3a of the nozzle body 3 through the edge of the bonnet A between the guide roller 5 and the nozzle portion 3b, 4 can accurately align with the sealer application portion of the back surface hemming portion B, and in this state, the application tool main body 1 is inclined in the moving direction so that the nozzle body 3 forms a certain angle θ with respect to the bonnet A.

As a result, a gap δ corresponding to the thickness of the sealer agent to be applied is set between the guide roller 5 and the sealer discharge port 4.
Is moved in the direction of the arrow shown in FIG.
The sealer 9 is correctly applied to the hemming portion B of the back surface.

[0013]

As described above, according to the present invention, a hook-shaped nozzle body is attached to the tip of the grip portion, and a slit-shaped sealer discharge port that opens toward the grip portion side at the hook-shaped bent portion. And a guide member that comes into contact with the upper surface of the object to be coated is mounted in parallel with the discharge port so as to face the sealer discharge port. If the applicator is moved over the object to be coated, the sealer can be accurately and easily applied to the hemming portion on the rear surface of the object to be applied in an easy posture and with reference to the end surface and the upper surface of the object.
