Description

  The present invention relates to a monocoque type assembling canoe that can be disassembled and assembled in a shorter time than a conventional product because it is lightweight, compact and easy to carry and has a small number of parts.

Conventionally, an assembly type canoe in which a pipe is assembled in a hull shape and the outside is covered with a sheet or cloth is known (see Patent Documents 1 to 4). Further, a boat is known in which each of the trunk portions obtained by dividing the hull into a ring shape is joined with a packing interposed therebetween (see Patent Documents 5 and 6). However, with the former pipe, the pipe part protrudes and the side surface and the bottom of the ship become convex, and this part is rubbed against rocks and the like, and the sheet is easily cut off, which is dangerous. In addition, the latter method of connecting the body parts that are divided into ring-shaped parts is weak when there are many parts to be divided, and there is a difficulty in preventing the ingress of water. There was a problem in terms of bulky conveyance of parts.

A canoe is preferred (claim 2).

  Since the monocoque type assembling canoe of the present invention has the joining structure as described above, the number of parts can be reduced and disassembly and assembly can be easily performed. Further, by making the joint part into a thin plate shape, an effective space in the ship is obtained. The storage capacity of the disassembled shell piece is compact and light in weight and convenient for transport.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention (hereinafter abbreviated as an embodiment) will be described below in detail with reference to the drawings. A monocoque type assembling canoe 1 according to the present invention includes a tension shell 3 formed by joining a flexible synthetic resin plate-shaped tension shell as shown in FIGS. And a support member 4 attached to the side plate portion of the tension shell body, and the outer side of the tension shell body 3 is covered with a waterproof hull bag 5 in a detachable and tensioned state. The material constituting the shell 3 is not particularly limited, and is an epoxy resin or unsaturated polyester resin and carbon fiber reinforced plastic (CFRP) mainly composed of carbon fiber, epoxy resin or unsaturated polyester resin, and the like. Glass fiber reinforced plastic (FRP) mainly composed of glass fiber is preferred.

  In addition, in order to reduce weight, improve strength and rigidity, a material obtained by laminating any one of the CFRP sheet or FRP sheet in a sandwich shape on both surfaces of a foam sheet in which a microballoon is held in a honeycomb shape on a nonwoven fabric substrate Is preferred. In addition to the foam sheet in which the microballoons are held in a honeycomb shape, the foamed resin such as azodicarbonamide or the like, and the foamed resin by a gas generated by the thermal decomposition of the foaming agent or the liquid resin composition were foamed by stirring. It may be a thing.

The shell piece 2 according to the present embodiment is composed of a plurality of cut pieces obtained by cutting a ship monocoque substantially perpendicular to the longitudinal direction. Then, as shown in FIG. 3, concave and convex portions 61a and 61b and corrugated portions 61'a and 61'b are formed on the joints 6 of the adjacent shell pieces 2a and 2b in plan view, respectively. In addition, joints 62a and 62b cut out at right angles are formed at the abutting portions of the side surfaces of the adjacent tension shell pieces, and the tension shell body is formed by joining the joints and the joints together. 3 is configured. There are no particular restrictions on how many of the shell monocoques 2 comprise the ship monocoque, but it can be set in consideration of the size and strength of the ship monocoque and the size of the shell monoke 2 when disassembled. In general, it is preferably composed of about 5 to 10 pieces.

  If the concavo-convex joint 61 provided in the joint portion 6 of the tension shell piece is formed into an undercut shape or a wave shape having a wide tip portion and a narrow base portion, a tensile force perpendicular to the joint surface is formed. It becomes difficult to come out with respect to force or torsional force in an oblique direction. In the present embodiment, the bottom plate portion is formed in a wave shape, and the side plate portion is formed in an uneven shape. For example, as shown in FIG. 5, joints 62 a and 62 b each having a L-shaped or inverted L-shaped longitudinal section are formed on the butted portion of the head portion of the tension shell piece joint. By combining the joints, the two shell pieces 2a and 2b can be joined in a substantially flat shape. Thus, as shown in FIG. 5 (c), the same direction perpendicular to the plane of each of the two shell pieces 2a and 2b with the joint 6 of the two adjacent shell pieces 2a and 2b as a fulcrum, as shown in FIG. The resistance force F against the external forces Fa and Fb is increased, and bending at the joint 6 of the stretched shell 3 can be prevented. By combining the assembling hand 61 and the joint 62 as described above, the ship monocoque can prevent disassembly of the shell piece due to the detachment of the joint portion with respect to the external force applied to the joint portion. Moreover, you may make it prevent the launch to the inside to the minimum by sealing the junction part 6 with an adhesive tape etc.

  Next, the support member etc. which support the tension shell 3 are demonstrated. The support member 4 is made of a relatively strong material, and a plurality of horizontal frames 41 bridged in a direction perpendicular to the longitudinal direction of the shell 3 and the plurality of horizontal frames 41 are respectively connected in the vertical direction. And a vertical frame 42. As shown in FIG. 6, the horizontal frame 41 includes a mountain-shaped upper arm portion 411 and both side arm portions 412 that are continuous with the upper arm portion, and the side facing the stretched shell side plate portion 31 of the both side arm portions and the stretched shell body bottom plate portion 32. Protrusion 413 is provided at the tip portion facing the surface, and a locking hole 63 is provided at a position facing the protrusion at the joint portion of the adjacent shell piece, so that the protrusion 413 is fitted into the locking hole 63. The locking hole made of the through hole is preferably configured such that the protrusion 413 passes through the locking hole 63 and is held substantially flush with the outer surface of the tension shell.

  On the other hand, as shown in FIG. 6, the connecting plate 65 for connecting the two shell pieces is fixed to one of the two shell pieces, and the other shell piece and the connecting plate are connected to each other. The penetrating locking grooves 64 a and 64 b are formed, the protruding end 414 of the upper arm portion 411 of the horizontal frame is passed through the locking groove 64, and the tip portion is fixed by the locking tool 415. A bolt may be attached to the protruding end portion of the upper arm portion and fixed with a nut from the outside of the side plate portion (not shown). As described above, the number of parts can be reduced because it is only necessary to fix the two side frames to the opposing side plate portions of the tension shell at two locations. The protrusions 413 passed through the locking holes 63 provided in the joint portions of the adjacent shell pieces serve as a hook, and can be prevented from being disconnected due to a force applied at a right angle to the joint surface. Then, the vertical frame 42 is connected and fixed to the apex portion of the upper arm portion 411 of the horizontal frame 41.

  As shown in FIG. 1, a circular or elliptical cockpit frame 7 is fixed in a suspended state so as to be held at a height approximately the same as a horizontal frame or a vertical frame, slightly rearward of the center of the shell. A seat 8 is provided inside the cockpit frame 7. Further, the whole shell member and the supporting member except for the inside of the cockpit frame 7 are covered with the waterproof hull bag 5 from the outside in a detachable and tensioned state so as to maintain a spindle-shaped boat shape. . The waterproof hull bag 5 is preferably made of a material obtained by bonding a cloth to a flexible synthetic resin film.

  In addition, an elongated air tube 51 is attached to the inside of the waterproof hull bag 5 along the upper longitudinal direction of the stretched shell body side plate portion. By press-fitting the air, the entire hull bag can be maintained in a tensioned state, and the stability of the ship is increased and the effect of preventing rollover is achieved. In addition, by attaching a thin air tube 52 to the center of the bottom of the hull bag 5 and at both side ends and press-fitting air, elasticity is maintained, and wear of the hull bag due to contact with stones etc. at the bottom of the river can be prevented during use. it can.

  Further, a pulley 10 is provided at the tip of the assembly type canoe, a string 11 is rotatably passed through the pulley, a load 12 is connected to one end of the string, and the other end of the string is pulled to pull the load. The baggage can be easily transferred to a storage unit provided on the front side in the boat, and the baggage can be transferred to the cockpit side by pulling a string connected to the baggage on the side opposite to the pulley. In addition to directly connecting the string to the luggage as described above, the luggage may be transferred by connecting the string to the transfer table, placing the package on the transfer table, and reciprocating the transfer table ( Not shown).

  Next, an example of a method for assembling the monocoque type assembling canoe 1 according to the embodiment will be described. First, after the tension shell pieces constituting the front part and the rear part of the tension shell 3 are assembled separately, each is inserted into the hull bag 5 and joined together. In order to join the adjacent shell pieces, as shown in FIG. 5, first, the adjacent shell pieces are combined in a mountain fold shape at the bottom plate portion 32, and then both the shell pieces 2a, 2b are combined. Is stretched and flattened, the joints and joints of the joint 6 are combined and joined together, and thereafter the joints and joints in the side plate 31 are inserted into each other and joined. Next, the horizontal frame 41, the vertical frame 42, the cockpit frame 7 and the seat portion 8 are respectively attached, and finally, air is press-fitted into the air tubes 51 and 52 attached in the hull bag by a pump, so that the hull form has a predetermined spindle shape. After being held in a shape, a pulley and a string for transferring goods are attached to the tip of the ship, and the loaded items are connected by the string to complete the assembly.

  Next, although an Example is described, this invention is not limited to this Example. The monocoque type assembling canoe 1 according to the embodiment has the CFRP sheet on both sides of a foam sheet in which a microballoon is held in a honeycomb shape on a nonwoven fabric base having a thickness of about 5 mm and a length of about 0.5 m. A stretched shell 3 having a total length of about 4 m, which is a combination of 8 stretched shell pieces 2 made of sandwiched material, a support member 4 made of FRP for supporting the stretched shell, a plastic provided in the cockpit frame 7 and the cockpit frame A tarpaulin waterproof hull bag 5 in which a fabric made of a plain weave structure using polyester filament yarn covering the canoe body and a flexible vinyl chloride resin film are laminated together, and the tip of the shell body And a string 11 connected to the pulley, and is configured substantially in the same manner as in the above embodiment. The volume of the assembled canoe after being disassembled and packed was about 70 liters. On the other hand, the volume in the case of the conventional assembly type canoe is about 100 to 110 liters, and the volume reduction rate is actually about 30% or more. In addition, since the number of parts and the number of joints are small and a strong force is not required for fitting between parts, it has been proved that the time for disassembly and assembly is greatly reduced.
