Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cowling attachment / detachment device of a marine propulsion device for attaching / detaching a top cowling in a marine aircraft or the like.

2. Description of the Related Art In an outboard motor or the like, an engine mounted on an upper portion of a propulsion casing is covered with a bottom cowling and a top cowling so that the engine can be protected from seawater, rainwater, and the like. Locking devices for fixing the top cowling to the bottom cowling are provided before and after the cowling. At this time, the top cowling needs to be removable from the bottom cowling if necessary,
If each of the front and rear locking devices is provided with an unlocking device, it is difficult to unlock the rear side.

As shown in Japanese Utility Model Application Laid-Open No. 59-54400, there has been proposed a conventional outboard motor in which two front and rear locking devices are connected by a cable extending inside a cowling and the front and rear locking devices are interlocked. I have. In this prior art, an unlocking operation force applied to an operation member provided inside and outside the front side of a cowling is directly transmitted to a front-side lock device, and the above-described operation force is applied to a rear-side lock device. Communicate via cable and release the front and rear locking devices simultaneously.

[Problems to be Solved by the Invention] However, in the above-mentioned prior art in which the rear-side lock device can be remotely operated, the operation member and the rear-side lock device are connected to each other, and the remote-control device extending in the cowling is connected. When the connecting cable is stretched or cut, the rear locking device can no longer be unlocked, making it very difficult to remove the top cowling.

In the case of cable trouble as described above, if on land, use a turning tool on the rear side of the cowling,
It is also conceivable to perform an unlocking operation of the rear locking device. However, on the water, it is not possible to recommend the above-described unlocking operation which requires a complicated tool operation by leaning out of the boat greatly. As a result, there is a possibility that maintenance for repairing the engine trouble on the water may become impossible, which is extremely inappropriate.

The present invention relates to a cowling attachment / detachment device in which an operating member and a lock member are interlocked with a cable, and the lock member is remotely operated.When the cable is stretched or cut, the lock member is securely and easily unlocked. The purpose is to make the cowling removable.

Means for Solving the Problems The present invention provides an engaged member provided on one of a bottom cowling and a top cowling, and a lock position provided on the other of the bottom cowling and the top cowling for holding the engaged member. A lock member movable between a release position for releasing the engaged member and a cowling, an operation member provided over the inside and outside of the cowling, and an operation member for remotely operating the lock member; In a cowling attachment / detachment device for a marine propulsion device including a cable for transmitting an operation force applied to the operation member to a driving portion of the lock member and moving the lock member in a release direction, the operation is performed outside the cowling. The emergency operating part to be operated and the emergency engaging part located in the cowling are connected via an emergency cable, and the emergency engaging part is added to the emergency operating part. The lock member is configured to move from a non-engagement position with respect to the drive unit to an engagement position with respect to the drive unit by an operation force applied thereto, and to move the lock member in a release direction. An emergency engagement portion setting member that constantly biases toward the engagement position is provided.

[Operation] The present invention has the following operation.

At the time of normal release, the operation force applied to the operation member is transmitted to the drive unit of the lock member via the cable, and the lock member is moved in the release direction. As a result, the lock member can be unlocked by remote control.

At the time of the normal release, the emergency engagement portion is always held at the non-engagement position with respect to the drive portion of the lock member by the emergency engagement portion setting member. Therefore, when the lock member is moved by the operation member and the cable, the drive unit of the lock member idles with respect to the emergency engagement unit,
The presence of the emergency engagement portion does not impair the remote operability for the lock member.

When the operating member and the drive unit of the lock member are connected, and the cable for remote operation extending in the cowling is extended or cut, the lock is applied by an operation applied to the emergency operation unit outside the cowling. The member can be unlocked. That is, the operating force applied to the emergency operating portion causes the emergency engaging portion located in the cowling via the emergency cable to engage with the driving portion of the lock member, and as a result, moves the lock member in the release direction, The lock member can be unlocked.

According to the above, the operating member and the lock member are interlocked by a cable, and in a cowling detachment device for remotely operating the lock member, when the cable is stretched or cut, the lock member is securely and easily unlocked, and Cowling can be removed.

Therefore, in the case of a cable trouble as described above, even if the cable is on the water, the above-described unlocking operation can be easily performed, and maintenance for repairing an engine trouble on the water can be appropriately performed.
