Description

The present invention relates to a cowling of an outboard motor, and more particularly to a structure of an apron extending from a lower end of a bottom cowl to an outer wall of a propulsion unit.

[Related Art] Conventionally, since a disengagement mechanism for disengaging and disengaging a bottom cowl and a top cowl is disposed in front and rear, two clamp levers for releasing this locking mechanism are provided forward and rearward from the bottom cowl. I was In recent years, as a cowling for an outboard motor, one having no irregularities on the outer surface has been favored in design.In order to eliminate irregularities, a clamp lever is provided only in front of the cowling, and a rear engaging and disengaging mechanism is provided by a front clamp. It is considered that the lever is configured to be linked with the lever via a wire or the like. However, there is a case where the wire for interlocking or the like is broken due to corrosion or other force majeure. In this case, it is impossible to remove the top cowl from the bottom cowl by operating the front clamp lever.

[Problems to be Solved by the Invention] Therefore, a hole is provided in the rear part of the cowling in the vicinity of the rear-side engaging / disengaging mechanism, and the rear side engaging mechanism is used by using the hole when an abnormal situation such as breakage of the wire occurs. Although it is conceivable to release the locking mechanism, it is not preferable to form a hole in the cowling in terms of design, and usually, even if the hole is closed, it is not preferable because unevenness occurs.

Therefore, remove the apron attached from the lower end of the bottom cowl to the outer wall of the propulsion unit, and use the hole existing between the upper end of the propulsion unit and the rear bottom surface of the bottom cowl to set the rear engagement / disengagement mechanism. It is conceivable to release it with a driver. However, locking means such as mounting bolts are required to attach the apron to the bottom cowl. To remove the apron, the locking means must be released from the outside, and the counterbore and locking The bolt head and the like of the means are visible on the outer surface, which is also undesirable in design.

The present invention has been made in view of such a point, and its object is to remove an apron which is vertically locked to a bottom cowl, and it is preferable in terms of design such as any irregularities on the outer surface of the apron. It is an object of the present invention to provide a cowling for an outboard motor in which the apron can be easily removed without any missing parts.

Means for Solving the Problems In order to achieve such an object, the present invention covers the engine located above the propulsion unit by mounting the top cowl on the bottom cowl, In a cowling of an outboard motor equipped with an apron extending from a lower end of a bottom cowl to an outer wall of the propulsion unit, the apron can be divided into a front apron covering a front part of the propulsion unit and a rear apron covering a rear part of the propulsion unit. The rear apron is vertically locked to the bottom cowl via locking means, and the locking means shifts the rear apron in a certain direction with respect to the bottom cowl to lock the rear cowl. It is configured to be released.

[Operation] With this configuration, the front apron is first removed, and the rear apron is moved in a certain direction to release the locking state of the locking means, whereby the rear apron can be removed from the bottom cowl. Therefore, when the interlocking of the front and rear disengagement mechanisms does not function, the apron is removed and the rear disengagement mechanism is utilized using a hole provided on the rear side of the bottom cowl lower surface using a driver or a hand. It can be canceled, and the occurrence of an abnormal situation can be dealt with without breaking the cowling or the like.

EXAMPLES The present invention will be described below based on examples shown in the drawings.

In FIG. 1, reference numeral 10 designates an outboard motor, the propulsion unit 12 of which is attached to a stern plate 14 of a hull by a clamp bracket.
It is mounted so as to be rotatable vertically and horizontally via a swivel bracket 16 and a swivel bracket 18. 13 is the swivel bracket 18
Is a tilt pin that supports the clamp bracket 16 so as to be rotatable up and down with respect to the clamp bracket 16, and 15 is a steering bracket.
An engine 20 is located above the propulsion unit 12, and the engine 20 is covered by a bottom cowl 22 and a top cowl 26 mounted on the bottom cowl 22 via a seal member 24. In this embodiment, in order to achieve a cowling with no irregularities, a clamp lever 30 operated when releasing the engagement / disengagement mechanism between the bottom cowl 22 and the top cowl 26 is provided in the recess 28 at the front position of the bottom cowl 22. Are located.

Reference numeral 32 denotes a so-called latch-and-strike type engagement / disengagement mechanism provided at the front and rear portions of the cowling, respectively. The top cowl 26 is attached to the bottom cowl 22 and the top cowl 26 is merely pressed by hand. A substantially L-shaped hook 34 hanging from the top cowl 26 is locked by a latch type locking member on the bottom cowl 22 side, and when releasing this locking, the clamp lever 30 must be rotated. As a result, the locking member resiliently releases the hook 34. Operation of the clamp lever 30 to engage and disengage the rear side
The engaging and disengaging mechanisms at the front and rear portions are connected to each other via a wire 36 in order to release the locking of the hook 34 by interlocking the 32.

2 and 3, reference numeral 38 denotes an apron extending from the lower end of the bottom cowl 22 to a substantially central outer wall of the propulsion unit 12. The apron 38 can be divided into a front apron 40 that covers the front part of the propulsion unit 12 and a rear apron 42 that covers the rear part, and a pair of mounting bolts are screwed from the front to the rear. Linked together by 44.
Although the head of the mounting bolt 44 is exposed to the outside, it is hardly noticeable from the outside due to the presence of the swivel bracket 18 and the like, and does not cause a great problem in design. Rear apron 42
Is connected to a mounting boss 48 of the bottom cowl 22 by a pair of mounting bolts 46 at the front upper end portion thereof.
46 is not visible from the outside.

Further, the rear apron 42 is vertically locked to the bottom cowl 22 by a pair of locking means 50 at the rear portion.
The locking means 50 is configured such that a mounting bolt 54 is screwed to a boss portion 56 of the rear apron 42 from above through a substantially bar-shaped mounting hole 52 formed in the bottom cowl 22. . 58 is color, 60 is rubber damper, 62
Is a washer, and the rubber damper 60 has a structure having a small-diameter body portion 60A at the center and a large-diameter head 60B at the upper and lower ends. Usually, the small-diameter portion 52 of the daruma-shaped mounting hole 52 is provided.
A body portion 60A having substantially the same diameter is fixed to A. Since the head 60B of the rubber damper 60 is slightly smaller in diameter than the large diameter portion 52B of the mounting hole 52, the locking means 50 is moved rearward in FIG. 2 together with the rear apron 42 itself.
The locking of the rear apron 42 and the bottom cowl 22 in the vertical direction by the locking means 50 is released, and the rear apron 42 together with the locking means 50 can be removed downward from the bottom cowl 22.

The bottom cowl 22 has a large notch 64 at the rear center of the bottom surface, as shown in FIG. 3, so that the propulsion unit can be removed by removing the rear apron 42.
A notch 64 opens between the rear wall 12 and the bottom cowl 22.
Accordingly, a space is formed such that a hand or the like can reach the rear engagement / disengagement mechanism 32 through the notch 64.

Reference numeral 66 denotes an exhaust guide interposed between the bottom cowl 22 and the rear apron 42.

With this configuration, when the rear engagement / disengagement mechanism 32 does not operate even when the clamp lever 30 is operated due to the breakage of the wire 36 or the like, the apron is removed by first removing the mounting bolt 44.
Remove the 38 front apron 40 from the propulsion unit 12. As a result, the mounting bolts 46 are exposed to the outside. Therefore, the mounting bolts 46 are removed, and then the rear apron 42 is pulled rearward in the horizontal direction. As a result, the rubber damper 60 that has been locked in the small diameter portion 52A of the mounting hole 52 moves to the large diameter portion 52B of the mounting hole 52, and the head 60B of the rubber damper 60 has a smaller diameter than the large diameter portion 52B. As a result, the entire locking means 50 can escape downward, whereby the rear apron 42 can be removed. As a result, the notch 64
Through the notch 64, the locking state of the engagement / disengagement mechanism 32 with respect to the hook 34 can be released by a driver or a hand, and the top cowl 26 can be removed.

It is conceivable that the front-side engaging / disengaging mechanism 32 cannot be released by the operation of the clamp lever 30, but in this case, the rear-side apron 42 of the apron 38 is removed to release the rear-side engaging / disengaging mechanism 32. The front cowl 26 can be pushed open from the rear and the front side engaging / disengaging mechanism 32 can be released using a long tool or the like.

[Effects] As described above, according to the present invention, even when the mechanism for engaging and disengaging the bottom cowl and the top cowl is disturbed, the cowls themselves are not provided with irregularities or holes without breaking both cowls. It is not necessary to manually operate the engaging and disengaging mechanism of both cowls provided at the front and rear portions, and there is an excellent effect that an emergency situation of the engaging and disengaging mechanism can be handled.
