Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mounting structure for an outboard motor.

[Prior art]

FIG. 1 shows how an outboard motor 2 is attached to a transom board 3a of a hull 3 using a conventional clamp bracket 1. As shown in FIG. The clamp bracket 1 consists of a symmetrically formed clamp left bracket 4 and a clamp right bracket (not shown), each of which is approximately U-shaped and has a screw hole 1b formed in its upper end 1a. . A clamp screw 6 with a handle 5 installed thereon is screwed into the screw hole 1b, and the upper end portion 1a of the clamp bracket 1 is screwed into the screw hole 1b.
is held on the transom board 3a by this clamp screw 6. On the other hand, insertion holes 3b and 1c are formed in the lower part of the transom board 3a and the clamp bracket 1, and the lower part of the clamp bracket 1 has a bolt 7 inserted through these insertion holes and a nut 7 screwed into the bolt.
It is fixed to the transom board 3a by a. In FIG. 1, reference numeral 8 indicates a clamp plate disposed between the clamp screw 6 and the transom board 3a.

As described above, in order to attach the outboard motor 2 to the transom board 3a using the conventional clamp bracket 1, the outboard motor 2 is first lowered from above and the clamp bracket 1 is fitted onto the transom board 3a. Next, the clamp screw 6 is inserted into the insertion hole 1b of the clamp bracket 1, and the clamp screw 6 is tightened by operating the handle 5, so that the clamp plate 8 is pressed against the transom board 3a. Further, at the lower end of the clamp bracket 1, a bolt 7 is inserted from the insertion hole 1c of the clamp bracket 1 into the insertion hole 3b of the transom board 3a, and a nut 7a is fastened to the bolt 7 to attach the clamp bracket 1 to the transom board. Fix it to 3a.

On the other hand, in order to remove the outboard motor 2 from the transom board 3a, first remove the nut 7a from the bolt 7, pull out the bolt 7 from the insertion hole 3b of the transom board 3a and the insertion hole 1c of the clamp bracket 1, and remove the bolt 7 from the clamp bracket 1. Unjoin the bottom edge of. Thereafter, operate the handle 5 to loosen the clamp screw 6 and remove the outboard motor 2.

Conventionally, the outboard motor 2 is attached and detached as described above.

However, in the past, when installing the outboard motor 2, the insertion hole 1 of the clamp bracket 1 was
It is difficult to match the insertion holes 1c and 3b of the transom board 3a, and in addition, it is necessary to fill the insertion holes 1c and 3b into which the bolts 7 are inserted with waterproof sealant. The installation workability of item 2 was poor.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide an outboard motor mounting structure that allows easy installation and removal of the outboard motor.

[Structure of the idea]

In order to achieve the above object, the present invention does not employ a bolt-and-nut connection in which a bolt is inserted between the transom board and the clamp bracket, but instead uses a guide for the clamp bracket on the outer wall surface of the transom board. The outboard motor is mounted on the hull by forming a groove and guiding the clamp bracket in the guide groove, and then inserting a pin between the transom board and the clamp bracket on the outer wall side of the transom board, thereby tightening the clamp. The lower part of the bracket is fixed to the transom board.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows the guide plate 11 used in the present invention, and FIG. 3 shows how the crank bracket 14 is assembled in an outboard motor.

In this embodiment, the guide plate 1 shown in FIG.
1 is attached in advance with bolts or the like. Two sets of holding plates 12 each having an L-shaped cross section are fixed to this guide plate 11, and a guide groove 13 is formed between them. Further, brackets 12a are provided upright at the bottom of each of these holding plates 12, and these brackets 12a
A is provided with an insertion hole 12b in a direction perpendicular to the direction in which the guide groove 13 is formed.

On the other hand, the clamp bracket 14 shown in FIG.
It consists of a clamp left bracket 15 and a clamp right bracket 16 that are formed in a substantially symmetrical shape, and these are connected together by a bolt 18 after a swivel bracket 17 is interposed therebetween. The lower portions of the clamp left bracket 15 and the clamp right bracket 16 have insertion holes 15a and 16a that correspond to the insertion holes 12b in the bracket 12a of the guide plate 11.
are formed respectively.

FIG. 4 shows an outboard motor installed according to the present invention. Below, Figure 2, Figure 3,
The mounting structure of the present invention will be explained with reference to FIG. The guide plate 11 is attached to the outer wall surface of the transom board 21a of the hull 21 with bolts 22. Transom board 21a with guide plate 11 installed in this way
To attach the outboard motor 23 to the motor, first lower the outboard motor from above and attach the overhanging portion 15b of the clamp left bracket 15 and the overhanging portion (not shown) of the clamp right bracket 16 of the outboard motor 23.
It is fitted onto the transom board 21a while being guided by the guide grooves 13, 13 of the guide plate 11.
Next, insert the clamp screws 24 and 25 into the insertion holes 15b and 16b of the clamp left bracket 15 and the clamp right bracket 16,
By operating the handles 26, 27, the clamp screws 24, 25 are tightened, and the clamp plates 28, 29 are pressed against the transom board 21a. Thereafter, the pin 30 is inserted into the insertion holes 15a and 16a of the clamp left bracket 15 and the clamp right bracket 16. As a result, the clamp bracket 14 is attached to the transom board 21a on the outer wall side of the transom board 21a.
1a is completely fixed. In FIG. 3, reference numerals 31 and 32 indicate pins for fixing the handles 26 and 27.

To remove the outboard motor 23 mounted in this manner from the transom board 21a, remove the pin 30 from the transom board 21a and the clamp bracket 14, operate the handles 26, 27, and remove the clamp screws 24, 25. relax,
After that, all you have to do is lift the outboard motor 23.

In this way, the present invention allows the outboard motor 23 to be easily installed without using sealants or tools such as spanners.
Installation and removal work can be carried out.

In the above embodiment, the guide groove 13 was formed in the guide plate 11 and the guide plate was attached to the transom board 21a, but the present invention is not limited to this embodiment. , it goes without saying that the guide groove 13 may be formed directly.

[Effect of idea]

As explained above, in the outboard motor mounting structure according to the present invention, the outboard motor is mounted by guiding the clamp bracket to the transom board of the hull provided with the guide groove. Since the outboard motor is fixed to the transom board by inserting a pin through the outboard motor and the transom board, the outboard motor can be easily attached and removed.
