Description

[Detailed description of the invention] Industrial application field: This invention is extremely easy to transport on-vehicle.
Moreover, it is convenient for boats that exhibit excellent handling stability.
This invention relates to a portable catamaran boat that can be assembled quickly.

Prior art: Boats used in still waters for communication, small transportation, etc., or recreational purposes such as fishing, sports, etc., and many of them are disassembled and reassembled to facilitate transportation on land. Among these prefabricated boats, as is well known from many publications (Japanese Patent Office bulletins, magazines, manufacturer's catalogs, etc.), the ones that are made from ordinary ship materials are the bow and stern of ordinary boats. , or divided into a bow section, a stern section, and a midsection. Various measures are taken to ensure that these two or three pieces fit together to form a minimum volume convenient for transportation. Inflatable types are folded for ease of handling, and rubber boats are commonly used that are inflated by supplying gas from a bellows or cylinder when in use.

However, in conventional prefabricated boats that are joined and separated in the width direction of the hull, when securing the joints for stable assembly, it is necessary to attach the necessary metal fittings below the waterline or to place the metal fittings through each other. Watertight means became necessary, making it difficult to balance safety and convenience. Also,
The joints became bulkhead-like or bulkhead-like obstacles, reducing the functionality of the boat. Furthermore, due to structural limitations, it had poor wave performance and maneuverability, and lacked stability.

Problem of the invention: The present invention was made in order to solve the above-mentioned problems.The purpose of this invention is to provide a portable catamaran boat that maintains the functions of the boat with excellent stability and has a folding mechanism that is easy to operate. It is an object.

Structure of the invention: The portable catamaran boat of the invention will be explained below. In the present invention, a twin hull is formed by two symmetrical hulls, and these two hulls are fixed at the freeboard. When used as a boat, a bench board extending to each outer side of both hulls is hung, and then the bench board and both hulls are detachably fixed. When not being used as a boat, the upper edges of both symmetrical hulls are butted against each other with the anchoring section as the rotation axis to form a foldable container body, and a bench board, oars, outboard motor, etc. are placed inside this container body. The structure is such that it can store tools and other necessary items, or be transported by vehicle.

Next, one embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 to 3, two symmetrical hulls 2 are placed side by side, and both hulls 2 are fixed together by a hinge 6 provided on the flange 3 of the upper edge of the freeboard. Next, a pliers board 4 extending to each outer side is hung over both hulls 2 forming a twin hull, and fixed to both hulls with fixing bolts 5. In this case, nut seats are glued to the back surface of the flange 3 at required locations on the outer and inner sides of the flange 3 of the hull 2 (for example, locations as shown in FIG. 1), and the fixing bolts 5
By hinge-fitting, the bench board 4 and both hulls can be removably fixed.

A catamaran boat 1 is formed by mounting an oar receiver 7, an outboard motor mounting seat 8, or both together on each hull 2. The catamaran boat 1 of the present invention includes a hinge 6 fixed to both hulls 2, a nut seat for a fixing bolt 5, an oar receiver 7, an outboard motor mounting seat 8, etc., or the hull 2 thereof.
All attachment points to the boat are located above the water line 9, and unlike conventional prefabricated boats, no special precautions are required for watertightness.

Effect of the invention: As described above, when the catamaran boat 1 is formed, the crew members can sit on the bench board and row with the oars, or move to any desired location by sailing with the outboard motor, or You can stop the ship and accomplish the desired objective.

Next, in order to fold the catamaran boat 1 of the present invention, the bench board 4 is removed and bent from the hinge 6 to include both hulls 2, 2 to form a container body as shown in FIG. A packing 11 is attached to the upper surface of the flange 3 of the hull. In the embodiment shown in FIG. 1, only one of the hulls has the packing 11, but it goes without saying that the packing 11 may be attached to both bodies. Then, when both hulls are put together, a box 12 can be formed by applying the clamp 10. This box 12
The bench board 4, as well as tools such as oars or outboard motors, as well as fishing tools, camping tools, etc. can be stored inside, and can be used as a carrier box while protecting them from the rain and wind.

Although the catamaran boat 1 of the present invention connects the two hulls with a hinge, it is also possible to connect the two hulls without coming alongside by using a connecting rod as another embodiment. It is.

Effects of the invention: As explained above, the portable catamaran boat of the invention has sufficient stability when used as a boat by adopting a twin hull, and has a box that can be closed when folded. It can be done. Therefore, efficient functions have been discovered for both boats and boxes, and they have great industrial applicability.
