Abstract

PURPOSE:To remove an apron easily by engagingly locking a rear side apron vertically to a bottom cowl through an engagingly locking means and moving the rear side apron in a specified direction against the bottom cowl through the engagingly locking means, thereby releasing the engagingly locked state. CONSTITUTION:Fitting bolts 44 are removed to take a front side apron 40 out of a propulsion unit so as to expose a fitting bolt 46. This fitting bolt 46 is removed, and a rear side apron 42 is pulled horizontally backward. Accordingly, elastic dampers 60 so far engagingly locked at the small diameter parts 52A of fitting holes 52 are moved to the large diameter parts of the fitting holes 52. As the head parts of the elastic dampers 60 are smaller in diameter than the large diameter parts 52B, the whole engagingly locking means slips out downward, and thus the apron 42 can be removed. As a result, a cutout 64 is exposed at the rear part of a bottom cowl 22, and the engagingly locked state against the hook of a disengaging mechanism is released through the cutout 64 so as to remove a top cowl.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cowling for an outboard motor, and more particularly to the structure of an apron extending from the lower end of a bottom cowl to the outer wall of a propulsion unit.

[Prior Art] Conventionally, a locking mechanism for locking and locking a bottom cowl and a top cowl is disposed in the front and rear, and a clamp lever for releasing the locking mechanism protrudes from the bottom cowl and has two locking mechanisms in the front and rear.
One was provided. Here, as an outboard motor cowling,
In recent years, a design with no unevenness on the outside has become preferred, and in order to eliminate unevenness, a clamp lever is provided only at the front of the cowling, and the rear engagement/disengagement mechanism is linked to the front clamp lever via wire etc. It is considered to be configured as follows. However, interlocking wires may be damaged due to R eclipse or other force majeure.
In this case, it is impossible to remove the top cowl from the bottom cowl even if the front clamp lever is operated.

[Problems to be Solved by the Invention] Therefore, a hole is provided in the rear of the cowling close to the rear side engagement/disengagement mechanism, and this hole is used to release the rear side in the event of an abnormal situation such as breakage of the above-mentioned wire. Although it is conceivable to release the locking/disengaging mechanism, forming a hole in the cowling is undesirable from a design point of view, and normally, even if the hole is closed, it is not suitable because unevenness will occur.

Therefore, we removed the apron that is attached from the bottom end of the bottom cowl to the outer wall of the propulsion unit, and used the hole between the top end of the propulsion unit and the rear bottom surface of the bottom cowl to open the rear engagement mechanism. It is possible to release it using a screwdriver, etc. However, in order to attach the apron to the bottom cowl, a locking means such as a bolt is required, but in order to remove the apron, this locking means must be released from the outside, and a counterbore or locking means is required to remove the apron. The bolt heads of the locking means are visible on the outer surface, which is also not desirable in terms of design.

The present invention has been made in view of the above points, and an object of the present invention is to prevent the outer surface of the apron from having any unevenness or the like, which is preferable in terms of design, when removing the apron that is vertically connected to the bottom cowl. To provide a cowling for an outboard motor from which the apron can be easily removed without leaving any parts missing.

[Means for Solving the Problems] In order to achieve the above object, the present invention covers the engine located at the upper part of the propulsion unit by attaching the top cowl to the bottom cowl, and also covers the engine located at the top of the propulsion unit. In a cowling of an outboard motor, an apron extending from the lower end of the bottom cowl to the outer wall of the propulsion unit is attached.

The apron can be divided into a front apron that covers the front part of the propulsion unit and a rear apron that covers the rear part, and the rear apron is vertically locked to the bottom cowl via a locking means, and The locking means is configured to release the locked state by moving the rear apron in a fixed direction relative to the bottom cowl.

[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, thereby allowing the rear apron to be removed from the bottom cowl.

Therefore, if the front and rear locking/unlocking mechanisms fail to function, remove the apron, use the hole on the rear side of the bottom cowl, and use a screwdriver or hand to open the rear locking/unlocking mechanism. It can be released, allowing you to deal with abnormal situations without destroying the cowling or the like.

[¥Example] The present invention will be explained below based on embodiments shown in the drawings.

In FIG. 1, the reference numeral 10 indicates an outboard motor, and its propulsion unit 12 is connected to the stern plate 14 of the hull via a clamp bracket 16 and a swivel bracket 18, so that the engine can be moved up and down.
It is mounted so that it can rotate left and right. 13 is a tilt pin that supports the swivel bracket 18 so as to be vertically rotatable 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 surrounded by a bottom cowl 22 and a top cowl 26 installed on the bottom cowl 22 via a seal member 24. In this embodiment, in order to achieve a cowling with no unevenness, a clamp lever 30 is provided in a recess 28 in the front position of the bottom cowl 22, which is operated when releasing the engagement/disengagement mechanism between the bottom cowl 22 and the top cowl 26. It is located.

Reference numeral 32 denotes a so-called latch-and-strike locking and disengaging mechanism provided at the front and rear portions of the cowling, respectively. Simply attach the top cowl 26 to the bottom cowl 22 and press the front and rear portions of the top surface of the top cowl 26 with your hands. An abbreviated hook 34 hanging from the top cowl 26 is locked to a latch-type locking member on the bottom cowl 22 side,
When releasing this locking, the locking member elastically moves the hook 34 by rotating the clamp lever 30.
It is something that liberates people. The front and rear locking mechanisms are connected to each other via a wire 36 so that the rear locking mechanism 32 is operated to release the hook 34 by operating the clamp lever 30.

Referring also to FIGS. 2 and 3, reference numeral 38 denotes an apron extending from the lower end of the bottom cowl 22 to the substantially central outer wall of the propulsion unit 12. This 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. They are connected to each other by bolts 44. Although the head of this mounting bolt 44 is exposed to the outside, it is not visible from the outside due to the presence of the swivel bracket 18, etc., and does not cause any major hindrance to the design. It is connected to a mounting boss 48 of the bottom cowl 22 by a pair of mounting bolts 46, and the mounting bolts 46 are 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 thereof. This locking means 50 connects a mounting bolt 54 to a boss portion 56 of the rear apron 42 from above through a substantially pot-shaped mounting hole 52 formed in the bottom cowl 22!
! ! It is constructed by being worn. Note that 58 is a collar, 60 is a rubber damper, and 62 is a washer. The body portion 80A having approximately the same diameter is fitted into the small diameter portion 52A of the potbell-shaped attachment hole 52 and fixed. rubber damper 6
By making the head portion 80B of the head 80B have a slightly smaller diameter than the large diameter portion 52B of the mounting hole 52, the locking means 50 is moved rearward in FIG. 2 along with the backup apron 42 itself. The vertical locking between the rear apron 42 and the bottom cowl 22 by the locking means 50 is released, and the locking means 50
At the same time, the backup apron 42 can be removed downward from the bottom cowl 22.

In addition, the bottom cowl 22 has a large notch 64 in the rear central part of the bottom surface, as shown in FIG.
Therefore, by removing the backup apron 42, a notch 64 is opened between the rear wall of the propulsion unit 12 and the bottom cowl 22. Therefore, a space is formed in which hands can reach the engagement/disengagement mechanism 32 on the rear side through the notch 64.

Note that reference numeral 66 is an exhaust guide interposed between the bottom cowl 22 and the rear apron 42.

With this configuration, if the wire 36 or the like is damaged and the rear locking/disengaging mechanism 32 does not operate even if the clamp lever 30 is operated, first remove the mounting bolts 44 to move the front apron 40 of the apron 38 to the propulsion unit 12. This exposes the mounting bolt 46 to the outside, so remove this mounting bolt 46 first and then remove it from the backup apron 4.
Pull 2 horizontally backward. As a result, the rubber damper 60, which has been locked to the small diameter portion 52A of the mounting hole 52,
moves to the large diameter portion 52B of the mounting hole 52.

Since the head SOB of the rubber damper 60 has a smaller diameter than the large diameter portion 52B, the entire locking means 50 can be pulled out downward, thereby allowing the rear apron 42 to be removed. As a result, a notch 64 is exposed at the rear of the bottom cowl 22, and the top cowl 26 can be removed by using a screwdriver or hand to release the locking state of the locking mechanism 32 to the hook 34 through the notch 64. .

Note that it is conceivable that the front locking/disengaging mechanism 32 cannot be released by operating the clamp lever 30, but even in this case, the rear apron 42 of the apron 38 is removed and the rear locking/disengaging mechanism 32 is released. It becomes possible to push open the top cowl 26 from the rear and release the engagement mechanism 32 on the front side using a long tool or the like.

[Effects] As explained above, according to the present invention, even if a problem occurs in the engagement and disengagement mechanism between the bottom cowl and the top cowl, one cowl will not be destroyed, and there will be no unevenness or holes in the cowl itself. It is now possible to manually operate the engagement and disengagement mechanisms for both the cowls provided at the front and rear without the need to provide them, and there is an excellent effect that an emergency situation of the engagement and disengagement mechanisms can be dealt with.
