The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a folding canoe that can be easily and quickly assembled and disassembled.

[Means to solve the problem]

The present invention provides a foldable canoe in which a hull frame made up of pipes is covered with a skin. Left and right pin fitting recesses provided on the plate and opening toward the left and right sides of the hull, respectively, left and right sleeve fitting parts provided on the coupling plate, and a side pipe extending along the side surface of the hull. , slots provided at the bow and stern ends of the side vibrator, and bins radially attached to the bow and stern ends of the side vibe at positions perpendicular to the cuts, respectively. ,
A locking member is housed in the vicinity of the bow and stern ends of the side vibe so as to be movable in the radial direction of the pipe so as to be able to protrude outside the pipe or retract into the pipe; A spring that urges the retaining material outward is slidably covered in the axial direction near the bow and stern ends of the side vibrator, and the pin fitting recess can be fitted to the inner circumferential side. and a sleeve, and the pin is in a state where the sleeve covers the locking material and the locking material is pushed into the side pipe, while inserting the coupling plate into the slit, The sleeve is fitted into the pin fitting recess of the coupling plate from the side, and after the pin is fitted into the pin fitting part, the sleeve is slid to a position where it is fitted into the sleeve fitting part. Then, a part of the coupling plate prevents further sliding, and at that time, the locking material is released from the sleeve and protrudes out of the side pipe, toward the locking material side of the sleeve. It is designed to prevent the regression of

[Effect]

In the present invention, when assembling the hull frame,
In a state where the sleeve covers the locking material and the locking material is pushed into the side vibrator, the pin is fitted into the pin fitting recess of the joint plate from the side while inserting the connecting plate into the cut. As a result, the side vibrator becomes unable to move in the axial direction with respect to the keel vibrator.

Next, when the sleeve is slid to a position where it fits into the sleeve fitting portion of the coupling plate, the sleeve becomes immobile in the lateral direction and is prevented from further sliding by a portion of the coupling plate. At that time, the locking member is released from the sleeve and protrudes outside the side pipe, thereby preventing the sleeve from retreating. Therefore, the sleeve is also locked in the axial direction, and as a result, the side vibrator cannot move laterally with respect to the keel pipe. As a result, the side vibe is fixed to the keel pipe in all directions.

On the other hand, when dismantling the hull frame, if you push the locking material by hand and slide the sleeve toward the locking material, the sleeve will cover the locking material, and the locking material will prevent the sleeve from sliding. Therefore, the sleeve and the sleeve fitting portion of the coupling plate can be disengaged and the side vibrator can be removed from the keel vibrator.
