Description

  The present invention relates to a collapsible canoe that is small folded and portable.

  Conventionally, there has been a folding canoe in which a hull is formed by assembling a large number of frame members into a hull shape and inserting the hull into a hull cloth.

  However, since many pipe-shaped frames were passed from the bow to the stern during assembly, it was not possible to make a waterproof bulkhead separating the cockpit part, bow part and stern part. Therefore, although it cannot be folded, compared with a resin-integrated canoe having a waterproof partition wall before and after the cockpit portion, there was much water during overturning and there was a risk of sinking.

  Moreover, around the cockpit, it was necessary to attach a large number of parts such as frames, cockpit combing, seats, and foot braces, and the number of parts increased. In addition, it is cramped by the protrusion of the frame, there is a danger that the body will be caught when overturning escape, and there is a risk that when the canoe lays on the rock, the frame tends to bend in the center of the cockpit, making it impossible to escape There was a problem with safety.

  In addition, when carrying a canoe in a folded state, a large bag for storing a large number of parts is required separately from the canoe body. In reality, the weight of the canoe body is heavy. It is generally carried on a carrier. However, when using a canoe, there was no need for a storage bag or a carrier, so it was a big obstacle.

  The present invention solves the above-described problems, and aims to reduce the number of parts, increase safety, and make a storage bag and a wheeled carrier unnecessary.

  In order to overcome the above problems, the present invention uses a bag-shaped frame member having an opening in the cockpit portion as one member of the frame constituent member.

  The bag-shaped frame member is sized such that a person can sit with its legs extended inside, and can store other frame members and the hull fabric during storage.

  Protrusions are integrally formed on the keel and chine portions of the bag-shaped frame member, and holes for connecting the pipe-shaped keel frame, chine frame, and deck frame extending toward the bow and stern are opened.

  It is also possible to connect wheels and handles to these holes during storage.

  Furthermore, the part of the bag-shaped frame member on which the person sits is integrally formed in a sheet shape, and other cockpit combing and foot brace are also attached at appropriate positions in advance.

  The material of the bag-shaped frame member is not particularly limited, but a highly rigid material such as fiber reinforced plastic is desirable.

  Air tubes are built into the port and starboard portions of the hull, and the maximum width of the bag-shaped frame member can be made smaller than the width of the hull when the hull is inflated. The size is about the same as a conventional folding canoe.

  With the above structure, the cockpit area, which has conventionally been composed of a large number of parts, is integrated, and the number of parts can be greatly reduced.

  In case of overturning, only the inside of the bag-shaped frame member needs to be submerged, and there is no bulging by the frame around the cockpit that existed in the conventional folding canoe. The bag-shaped frame member can prevent the cockpit portion from being broken and improve safety.

  The bag-shaped frame member that forms part of the frame itself acts as a storage bag, eliminating the need for a storage bag that was obstructive when using a conventional folding canoe, further reducing weight and simplifying It became possible.

Hereinafter, the features of the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a perspective view of the frame structure of the present invention as seen from the port side.
FIG. 2 is a view of the frame structure and the air tube of the present invention as viewed from the deck side and the port side.
FIG. 3 is a cross-sectional view taken along 16a to 16b of FIG.
FIG. 4 is a view in which the hull cloth of the stern deck portion is opened with the folding canoe of the present invention assembled.

  The folding canoe of the present embodiment mainly comprises a hull fabric 10 provided with a frame shown in FIG. 1 and air tubes 11a to 11b shown in FIGS.

  As shown in FIG. 1, the frame includes a bag-shaped frame member 5 and keel frames 1e to 1h, deck frames 1a to 1d, chine frames 6a to 6d, and rib frames 2a to 2b.

  As shown in FIG. 2, cockpit combing 7, seat 8, and backrest 9 are attached in advance to the bag-shaped frame member 5, and as shown in FIG. 3, the air tubes 11 a to 11 b are arranged at appropriate positions. Thus, the port and starboard portions are molded into a shape with a depression. Further, the keel and chine portions are also formed in a protruding shape, and give appropriate tension to the hull fabric 10.

  Further, the bag-shaped frame member 5 is formed with a hole for inserting the keel frame 1f as shown in a sectional view along 17a-17b shown in FIG. Holes for inserting the frames 1b to 1c and the chine frames 6a to 6d are also formed.

  As shown in FIG. 2, the maximum width of the bag-shaped frame member 5 can be made smaller by the air tubes 11a to 11b than the completed canoe hull width, and the storage size is smaller than the canoe hull width.

  As shown in FIG. 5, the keel frames 1e to 1f, the deck frames 1a to 1b, and the rib frame 2a are all connected together by shock cords 3a to 3b and rivets 4a to 4b. The rib frame 2a is rotatable, and the keel frame 1f is inserted into the keel frame 1e to maintain the keel straight line. Similarly, the deck frame 1b is inserted into the deck frame 1a to maintain the straight line of the deck.

  Similarly to the above 23, the keel frames 1g to 1h, the deck frames 1c to 1d, and the rib frame 2b are all connected together and can be folded as shown in FIG.

  FIG. 7 shows the storage state of the folding canoe of the present invention.

  The keel frames 1e to 1h, the deck frames 1a to 1d, the rib frames 2a to 2b, the chines frames 6a to 6d, and the hull fabric 10 that are folded as shown in FIG. 5 can be stored inside the bag-shaped frame member 5, and the wheels. 13. If the handle 15 is attached, it can be transported without using force.

  The wheel 13 and the handle 15 can be made detachable, or can be folded while attached so that the protrusion becomes small.

  The folding canoe having the above structure is assembled from the stowed state of FIG. 7, a bow-side frame member connected together as shown in FIG. 5, a similar stern-side frame member, chine frames 6 a to 6 d, The hull fabric 10 is taken out, the bow-side and stern-side frame members are straightened and connected to the bag-shaped frame member 5, and the rib frames 2a to 2b are rotated 90 degrees. The chine frames 6a to 6d are also connected to the bag-shaped frame member 5 and further connected to the rib frames 2a to 2b to complete the frame.

  Then, as shown in FIG. 4, by inserting the completed frame from the stern part opening of the hull cloth 10, closing the fasteners 12a to 12b, tightening the cockpit outer periphery string 14, and press-fitting air into the air tubes 11a to 11b. The hull fabric 10 expands to form a rigid hull.

  It is the perspective view which looked at the frame structure of the folding canoe of the present invention from the port side.   It is the figure which looked at the frame structure and air tube of the folding canoe of this invention from the deck side and the port side.   It is sectional drawing cut | disconnected along 16a-16b of FIG.   It is the figure which opened the hull cloth of the stern deck part in the state which assembled the folding canoe of this invention.   It is a figure of the state which folded the frame member by the side of a bow.   FIG. 17 is a cross-sectional view taken along FIGS. 3 and 17a to 17b of a portion where the bow-side frame member is inserted into the bag-shaped frame member.   It is a figure of the state which accommodated the other handle | frame and hull cloth in the bag-shaped frame member, and attached the handle for carrying and a wheel.
