Abstract

PURPOSE:To constantly enable smooth turning of a clamp lever by disposing a clamp lever supporting part above the window opened on a bottom cowling and closing the window with a sealing member, with the crank lever clamped. CONSTITUTION:At one side of a cowling 20, a hook 22 is fixed to the inner face of a top cowling 20b with a sealing member 26 therebetween and engaged in the recess 24 formed on the inner face of a bottom cowling 20a. At the other side of the cowling 20, another hook 32 is fixed to the inner face of a top cowling 20b and a clamp device 30 wherein a crank lever 42 is pivotally supported with a bolt 44 is attached from the inside to the window 34 of the bottom cowling 20a with a sealing member 36 disposed therebetween. And the device 30 is made into engagement with the hook 32 by turning the crank lever 42 on the outside of the cowling. The sealing member 36 has a slit 36a through which the lever 42 passes, whereby preventing entry of sea water and handling the lever 42 smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a clamping device for an engine cowling of an outboard motor.

(Prior Art) An outboard engine is usually entirely covered with a bottom cowling and a top cowling, and the top cowling can be attached to the bottom. In conventional cowlings, a hook is fixed to the inner wall of one of the bottom and top cowlings, a clamp lever is fixed to the inner end of a support shaft that penetrates the other wall almost horizontally, and a lever is fixed to the outer end of this support shaft. The spindle and the clamp lever are rotated by the lever, and the clamp lever is engaged with and disengaged from the hook. This is because in conventional devices, the support shaft protrudes into the outer wall of the cowling.

Seawater easily enters the bearing portion of this support shaft, and the clamp lever may not rotate smoothly due to rust or the like.

(Objective of the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cowling clamp device for an outboard motor, in which the bearing portion of the clamp lever is not exposed outside the cowling and smooth operation is always obtained. With the goal.

(Structure of the Invention) In order to achieve this object, the present invention arranges the bearing portion of the clamp bracket inside the cowling to prevent it from being exposed to seawater or the like. Namely, a hook fixed to the inner surface of the top cowling, a window formed in the bottom cowling so as to be located below the hook, a support part facing near the upper part of this window, and a rotatably supported part on the support part. The clamp lever is provided with a clamp lever that penetrates the window, and a seal member that closes the window when the clamp lever is engaged with the hook, and the support portion is located inside the cowling. The present invention will be described in detail below based on the illustrated embodiments.

(Example) The first factor is a side view of the outboard motor according to the present invention, FIG. 2 is an enlarged sectional view of the recess, and FIG.
The enlarged cross-sectional view of the recess in the figure, and FIGS. 4 and 5 are the flat surface view and the cross-sectional thickness near the line ■-V in FIG. 3.

In FIG. 1, the reference numeral 10 is a propulsion unit, and the attachment 12. Lower casing 14. Propulsion propeller 16. Upper casing 12 Ueda Maro I also visited engine 1
Equipped with 8th grade. The engine 18 is covered by a cowling 20, and the cowling 20 includes a bottom cowling 20a that is fixed to the upper casing 12 and covers a lower part of the engine 18.

A top cowling 201 is detachably attached to the bottom cowling 20a and covers two parts of the engine 18.

The front part of the bottom and one-tube cowlings 20a and 20b shown in FIG. 1 is as shown in FIG.

The lower ends of the hooks 22 fixed to the inner surface of the top cowling 20b are engaged with the recesses 24 formed in the inner surface of the bottom cowling 20a. 26 is the bottom and top cowling 20a.

This is a sealing member which is held between the parts 20b and 20b and seals the joint part watertightly.

The rear portions of the bottom and top cowlings 20a, 20b shown in FIG. 1 are joined together by a clamp device 30 shown in FIGS. In FIG. 3, 32 is a hook fixed to the inner surface of the top cowling 20b. Bottom cowling 20a
A window 34 is formed below the hook 32.

A rubber seal member 36 is attached to the window 34 from inside the cowling 20 to close the window 34.

The periphery of the upper surface of this seal member 36 is the bottom placket) 20
An annular member 38 fixed to a (pressed from two sides) is integrally formed with the fixing member 38. A supporting RFI 14o facing near the center of the sealing member 36, that is, above the window 34 is integrally formed. 42 is a clamp lever. -, it passes through the window 34 up and down through the slit 3fia provided in the sealing member 36, and is rotatably housed in the support portion 40.

44 is a bolt for tightening this clamp V bar 4 i f. The clamp lever 42 is in the actual position (clamp position) in Fig. 5, and its second part is in the 7th position (clamp position) as shown in Fig. 3.
, and comes off from the hook 32 at the imaginary line position (released position). Note that the sealing member 36 (36a) is as follows.

As shown in FIG.
The other parts are made to close, and when the clamp lever 42 is rotated to the release position, the clamp lever 42 opens the slit 3.
Push open the closed part of 6a.

When removing the top cowling 20b, rotate the clamp lever 42 to the imaginary line position in FIG.

The crank lever 42 is removed from the hook 32. Therefore, it is sufficient to lift the rear part of the top cowling 20b and pull out the hook 22 at the exposed front end from the recess 24. When attaching the top cowling 20b, the hook 22 is engaged in the recess 24 in the opposite manner to the above, and the rear portion is pushed down to rotate the clamp lever 42 from the imaginary line position to the solid line position.

Further, the supporting portion of the clamp lever 42 is located above the sealing member 36, that is, inside the cowling 20 (with knee).
Further, in the clamped state in which the top cowling 20b is fixed, the seal member 36 closes the window 34.

The clamp lever 42 always rotates smoothly so that seawater does not hit the supporting portion and rust occurs.

FIGS. 6 and 7 are a plan sectional view and a sectional view taken at a position corresponding to line 2--2, respectively, showing a second embodiment of the clamping device. In the clamp device 30A of this embodiment, a seal member 36A and a press plate 50 are fixed to a clamp lever 42A, and when the clamp lever 42A is in the clamp position (solid line position in Figure S57), the press plate 50 holds the seal member 36A and the press plate 50 is attached to the window 34A. It is designed to be pressed against the periphery. In this case, the seal member 36A
The end 36Aa on the bolt 44 side is the upright edge 34 of the window 34A.
Pressed perpendicular to Aa. 4. FIGS. 8 and 9 are a plan sectional view and a sectional view taken at a position corresponding to the line ■-■, showing the third embodiment of the clamping device. In the clamping device 30B of this embodiment, the support portion 40B is slightly deviated to the side near the upper part of the window 34B, so that the entire lower surface of the periphery of the sealing member 36B rests on the stepped periphery 34Ba of y 34B. It is something. As a result, the water quality is improved compared to those shown in FIGS. 6 and 7. 50B is the seal member 36B
This is a presser plate fixed to the clamp lever 42B so as to press it against the circumference 134Ba.

Note that in FIGS. 6 to 9, parts corresponding to those in FIGS. 4 and 5 are given the same reference numerals, so the description thereof will not be repeated.

(Effects of the Invention) As described above, in the present invention, the support part of the clamp lever is provided near the upper part of the window, and the sealing member closes the window when the clamp lever is in the clamped state, so that seawater does not hit the support part of the clamp lever. To prevent rust from occurring, clamp lever
will always rotate smoothly.
