Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a canoe that can be inflated and deflated by introducing and discharging air, and the seating part has been devised.

[Conventional technology]

Conventionally, a board made of a soft synthetic resin sheet and equipped with a hollow backrest and a seat made of the same material has been installed on the inner periphery of a hull made of synthetic resin such as vinyl, which has the same effect as the hull. A hollow frame body made of the material is provided, a hollow tube-like bottom body made of the above-mentioned material is stretched at the bottom of the hollow frame body, and a hollow partition body made of the above-mentioned material is installed horizontally at an appropriate position of the hollow frame body. A cutout of the required size is bored in the top plate of the hull at the front and back of the hollow partition, and a seat body into which air can be freely blown is inserted into the hull through the cutout. A hollow board with a seat attached to the seat is known from Japanese Utility Model Publication No. 36-1164.

[Problem that the invention attempts to solve]

However, although this type of structure has the advantage of being able to change the seat body forward or backward, the seat body can only be installed in the hull through a cutout protruding from the seat body and the top plate of the hull. This is done by simply placing the backrest on the bottom plate and touching the cutting edge of the cutout, but if the holding is extremely unstable and the ship is traveling at high speed, the seat body There were problems with it, such as it sliding around and being dangerous.

[Means for solving problems]

The present invention uses expandable and contractible hollow bodies made of thermoplastic soft synthetic resin sheets to form bottom wall 1, left wall 2, and right wall 3.
In the canoe 4, the left and right attachment parts, which are detachably attached to the upper edge of the left wall 2 and the upper edge of the right wall 3, are made of thermoplastic soft synthetic resin sheets that can be exchanged with each other. Expandable hollow crosspiece member 5
In addition, the portion on the parallel horizontal line extending vertically from the front edge 5' of the crosspiece member 5 is configured to be bendable, and by alternating the mounting position of the crosspiece member from left to right, it can be oriented forward or backward. a hollow backrest portion 6;
The backrest part 6 is provided with a hollow seat part 7 made of the same material and having a bendable portion on a parallel horizontal line extending from the lower edge of the backrest part 6, and the seat part 7 is placed on the bottom wall 1. The present invention attempts to solve the above-mentioned problems by providing a canoe characterized by the following, and by making the front and rear directions of the seat body freely changeable and increasing its safety.

〔Example〕

The embodiment shown in the figure shows the bow and stern portions of a canoe main body 4, in which a bottom wall 1, a left wall 2, and a right wall 3 are formed by consecutively expanding and contracting hollow bodies 9 made of a thermoplastic soft synthetic resin sheet. A triangular lid member 11, 11' made of a thermoplastic soft synthetic resin sheet that maintains its shape due to the existence of a bone portion 10 that hardens when air is introduced is arranged on the upper surface of the portion, and these lid members 11, 11' A hollow backrest part 13 is detachably fixed to the canoe body 4 by a string material 12, and is bendable at a point on a horizontal line parallel to the front edge of the lid member 11' on the stern side.
Further, a hollow seat part 14 having a bendable structure at a point on a horizontal line parallel to the lower edge of this backrest part 13 is integrally extended, and the seat part 14 is placed on the bottom wall 1. Separately from this, a hollow crosspiece member 5 which can be expanded and contracted is made of a thermoplastic soft synthetic resin sheet, and a portion of the crosspiece member 5 on a parallel horizontal line extending from the front edge 5' is bendable. The hollow backrest part 6 is vertically arranged, and the part on the horizontal line parallel to the lower edge of the backrest part 6 is bendable, and the mounting position of the crosspiece member 5 is also changed from left to right, so that it faces forward. A hollow seat part 7 that faces upward and backward is extended, and the crossbar member 5 is passed between the middle part of the upper edge of the left wall 2 and the middle part of the upper edge of the right wall 3, and both ends of the crossbar member 5 are extended. The parts are mounted on the port and starboard sides and are removably fixed with string material 15, and this fixing allows the seat part 7 to be attached to the bottom wall 1.
It is placed on top of the .

In addition, 17 in the figure indicates a supply/exhaust plug.

[Function] and [Effect of the invention] Since the present invention has the above-mentioned configuration, the backrest and the seat can be moved forward by alternating the left and right crossbar members and attaching them to the left and right walls of the canoe body. Of course, it is convenient to be able to change it to face backwards, but the backrest and the seat are integral with each other, and at the same time, the backrest extends integrally from the crossbar member, and the crossbar has both ends. Since the backrest and the seat are fixed to both the left and right walls of the canoe body, the backrest and the seat are securely held in the canoe. This has the effect of sufficiently solving the above problems.
