Description

[Detailed Description of the Invention] The present invention relates to a cover seal device for an outboard motor.

Conventionally, this type of product was constructed by attaching a cover seal made of NBR-based solid rubber extrusion or modified PVC extrusion to an FRP cowl using staples (large staple-like fasteners). .

However, in this case, there was a drawback that the number of man-hours required for installation was increased and the cowling was damaged.

The present invention was developed in view of the above circumstances, and its purpose is to greatly reduce the number of installation steps compared to conventional methods, and in particular to improve the sealing function of ships. An object of the present invention is to provide a cover sealing device for an external engine.

Hereinafter, the present invention will be explained with reference to the drawings.

Reference numeral 1 in the drawings indicates a cover seal body, and the cover seal body 1 includes a mounting portion 2 and a seal portion 3. The mounting part 2 covers a core material 4 having a substantially U-shaped cross section with an elastic member 5, and tongue pieces 9, 10 made of protrusions are provided on opposing wall surfaces 7, 8 of a substantially U-shaped mounting groove 6 formed by these members. It is constructed by protruding one or more pairs of. Further, one side of the opening of the mounting groove 6 is extended from the other side, and a protrusion 12 is formed on the inner surface of this extension 11.
is formed.

The seal portion 3 includes an outer shell member 3A that protrudes in an approximately arch shape and forms a sealing surface, and the outer shell member 3A.
and an elastic member 5, and a roughly Y-shaped rib member 14 that partitions the hollow portion 13 formed inside the elastic member 5 into three spaces.
The elastic member 5 and the elastic member 5 are integrally formed of the same material.

Further, the cover seal main body 1 is provided with a thick protection part 15 made of an elastic member 5 on the outer surface of one side of the mounting part 2, and this protection part 15 extends to the seal part 3.

The elastic member 5 may be made of modified soft vinyl chloride, synthetic rubber, or a mixture of synthetic rubber and PVC.

The mounting portion 2, the seal portion 3, and the protection portion 15 are integrally molded by simultaneous extrusion molding.

The cover seal device A configured in this manner is attached to the top cowling B of an outboard motor as shown in Fig. 2, and to the bottom body C of the outboard motor as shown in Fig. 3. There are cases.

When installing the cover seal device A on the top cowling B side, use the installation groove 6 of the cover seal device A.
Place the opening of the top cowling B on the edge surface of the mounting edge D of the top cowling B and push the cover seal mounting A into the mounting groove 6.
This is done by inserting it into the body and holding the mounting edge D between the tongue pieces 9 and 10.

Therefore, the shielding part 15 is located outside the top cowling B, and serves not only as a shielding material but also as a decoration.

Sealing is performed by bringing the seal portion 3 of the cover seal device A into contact with the seal surface F of the seal seat portion E of the bottom body C. At this time, the rib member 14 improves the reaction force during sealing.

That is, when the outer shell member 3A is pressed in the direction of the center line of the mounting groove 6 as shown in FIG. 2, the rib members 14 support the outer shell member 3A with high stiffness, so that high sealing performance is ensured.

When the cover seal device A is installed on the top cowling B side in this way, the cover seal body 1 can be expected to have a protection effect, and the bottom body C
There is no need to create a new Al die-cast mold, and the advantage is that conventional products can be used.

In addition, when installing the cover seal main body 1 on the bottom main body C side, use the mounting groove 6 of the cover seal mounting A.
By placing the opening of the holder on the edge surface of the mounting edge G formed on the bottom main body C and pushing in the cover seal attachment A, the attachment edge G is inserted into the attachment groove 6, and the tongue pieces 9 and 10 are used to close the attachment edge. Perform this by holding G in place.

In this case, sealing is performed by bringing the lower inner surface of the top cowling B into contact with the outer surface of the seal portion 3 and the surface of the shielding portion 15.

In the seal portion 3, the rib member 14 improves the reaction force during sealing.

That is, when the outer shell member 3A is pressed obliquely from above as shown in FIG. 3, the member 14 supports the outer shell member 3A with high stiffness, so that high sealing performance is ensured.

In this way, attach the cover seal A to the bottom body C.
When attached to the side, the sealing surface of this cover seal attachment A can be increased and the sealing effect will be good.

As described above, the present invention includes the cover seal body 1
Tongue pieces 9 and 10 face the mounting groove 6 formed by covering the core material 4 having a substantially U-shaped cross section with the elastic member 5.
The cover seal main body 1 is provided with a sealing portion 3 on the side opposite to the mounting groove portion 6 of the mounting portion 2, and this sealing portion 3 protrudes in a generally arched shape to form a sealing surface. An outer shell member 3A to be formed;
A roughly Y-shaped rib member 14 that partitions the hollow portion 13 formed inside the outer shell member 3A and the elastic member 5 into three spaces is integrally formed of the same material as the elastic member 5. This is an outboard motor cover seal device characterized by the following. Therefore, in this cover seal device, the mounting edges D, G of the top cowling B or bottom body C of the outboard motor are inserted into the mounting groove 6 in the mounting portion 2, and the mounting edges D, G are sealed by the tongue pieces 9, 10. By holding G in place, it can be attached to the top cowling B or bottom body C of the outboard motor, and the number of installation steps can be greatly reduced compared to conventional ones. In particular, when the seal portion 3 has the above-described configuration and the outer shell member 3A is pressed in the direction of the center line of the mounting groove 6 or when the outer shell member 3A is pressed diagonally from above, the rib member 14 presses the outer shell member 3A. Support with high stiffness ensures high sealing performance.
