Description

[Detailed explanation of the idea] [Technical field of invention] This invention relates to a mounting device for an outboard motor.

[Technical background of the invention and its problems]

In the conventional clamp mechanism for attaching an outboard motor to a transom, as shown in FIG. A handle 5 is attached to the outer end of the U 4, and a presser plate 6 is attached to the other end.To attach the transom 7 of the hull, hook the clamp bracket 3 onto the transom 7 as shown in the figure, and tighten the clamp. Rotate the handle 5 of the screw 4, screw it in, and press the presser plate 6.
is pressed against the transom 7 and fixed.

However, if only the clamp screw 4 is used, it may become loose due to vibrations of the outboard motor 1 and the outboard motor 1 may fall off the transom 7. 8 to ensure that both are fixed.

However, in the conventional structure described above, a tightening bolt 8 is used in addition to the clamp screw 4, so in order to tighten the tightening bolt 8, the head 8a of the bolt 8 and the nut 8b are simultaneously tightened. The tightening operation must be performed using a type of tool,
The drawback was that the tightening work was not easy.

Therefore, as shown in FIG. 3, the tip of the clamp screw 4 is extended and a thread is formed on its outer periphery, and this extended portion 4a is inserted through the transom 7 and the clamp bracket 3, and a nut is inserted into the protruding end. 9 to attach the outboard motor 1 to the transom 7.
The applicant has proposed a system in which the outboard motor 1 is fixed to the transom 7, but when the outboard motor 1 is removed from the transom 7, the clamp screw 4 must be completely removed from the transom 7, which is time-consuming. There was a problem with it hanging.

[Purpose of invention]

This invention focuses on the above-mentioned shortcomings of the conventional technology and aims to improve them.The outboard motor can be attached and detached from the transom using a single general-purpose tool, and the transom bolts are not attached. However, the present invention provides an outboard motor mounting device that can be mounted by simply screwing in a clamp screw in the same manner as before.

[Summary of the idea]

In order to achieve the above object, this invention has been developed in a clamp mechanism that attaches an outboard motor to the transom of a hull using a clamp screw that is screwed into the clamp bracket. A transom bolt, which is inserted into the transom from the rear side, is screwed into the screw hole of the clamp screw.

[Example of idea]

An embodiment of this invention will be described below with reference to FIG. 1, using the same reference numerals for parts common to those in FIGS. 2 and 3.

A screw hole 10 is formed in the axial direction from the tip of the clamp screw 4 which is screwed into the front part 3a of the clamp bracket 3, and a transom bolt 11 is screwed into the screw hole 10. The transom bolt 11 is inserted through a through hole 12 formed in the rear part 3b of the clamp bracket 3 on the same axis as the clamp screw 4 and a through hole 13 formed in the transom 7, and then inserted into the clamp screw 4. It is adapted to be screwed into the screw hole 10 of the.

A handle 5 for rotational operation is attached to the outer end of the clamp screw 4 by a pin 14 so that it can be raised and lowered freely, and a presser plate 6 that presses against the transom 7 is attached to the inner end of the clamp screw 4. There is.

Therefore, in order to attach the outboard motor 1 to the hull,
The outboard motor 1 can be mounted using only the clamp screw 4 by fitting the clamp bracket 3 onto the transom 7, screwing in the clamp screw 4, and crimping the holding plate 6 onto the transom 7.

To securely attach the outboard motor 1 with transom bolts 11 to prevent it from falling off, insert the transom bolts 11 from the rear into the through holes 12 of the rear part 3b of the clamp bracket 3, and then insert the transom bolts 11 through the through holes 13 of the transom 7. Clamp screw 4 screw hole 1
0 and head 1 of this transom bolt 11.
By fitting and tightening a tool into 1a, the clamp screw 4 is in a fixed state without loosening.

When removing outboard motor 1, remove transom bolt 1.
It can be removed by loosening 1 and pulling it out, and then loosening the clamp screw 4.
In this case, clamp screw 4 is
Since it is press-fitted and fixed, it can be worked with a single tool such as a spanner.

(Effect of the invention) As described above, this invention provides a screw hole in the axial direction from the tip of the clamp screw in the clamp mechanism that attaches the outboard motor to the transom of the hull using the clamp screw screwed into the clamp bracket. Since the transom bolt, which is inserted into the clamp bracket and the transom from the rear side, is screwed into the screw hole of the clamp screw, the transom bolt and the clamp screw are tightened in the direction in which they attract each other, and the transom is clamped. This significantly increases the mounting strength of the outboard motor, and when tightening or removing the transom bolt, you only need to fit the tool into the head of the transom bolt and rotate it, so you can do it with just one tool. It has various excellent effects, such as making it easy to attach and detach the outboard motor, and when installing using only the clamp screw, it is only necessary to tighten the clamp screw as in the conventional method.
