Description

The present invention relates to a retractable kayak.

Conventionally, kayaks that can be compactly stored include inflatable kayaks that can be used as boats from the state where the kayak was stored by inflating the tube by sending air into the tubes that make up the hull, or split during storage. It is known to be a folding kayak that is used as a boat by joining the parts that have been used by joining it by operations such as fitting to form the skeleton of the kayak and covering it with a highly waterproof cover.

Patent Document 1 discloses an inflatable kayak. As mentioned above, the work of sending air is required. Therefore, in many cases, air is sent using an electric air blower. That is, a power source such as a battery is required for the device.

The primary purpose of the kayak described in US Pat. No. 6,037,037 was to compactly store the kayak, including the purpose of allowing the kayak to be carried by means other than a car. .. However, when an air supply device and a battery are needed, it is difficult to carry them by means other than a car.

The folding kayak as described in Patent Document 2 was also developed for the purpose of carrying the kayak by means other than the vehicle. However, the folding kayak has a problem that the size after the kayak is stored is large and the mass is large, and it is difficult to carry the kayak by means other than the vehicle. This is because the material of the skeleton that makes up the kayak is metal, so if the skeleton is disassembled too finely when it is split and stored, the number of parts will increase during assembly and the work will become complicated, This is because each part must have a certain size.

Further, both the inflatable kayak and the folding kayak as described above have a drawback that it takes a lot of time for an assembling work from a storage state to a usable state.

As shown in FIG. 1, the tubular member corresponds to the reference numerals 1, 2, 3 in FIG. As shown in FIG. 4, the tubular member forms a hull by drawing a curved line peculiar to a kayak, as the tip end becomes closer as it extends toward the bow and the ledge.

As shown in FIG. 1, a tubular member having a hollow structure that becomes narrower toward the tip is fitted with a plurality of tubular members whose diameters are reduced toward the tips of the front and rear members, and when the tube member is extended most, This is a member configured such that the inner tubular member is closely fixed to the outer tubular member and is not separated . The material used for the elastic member, glass fibers, carbon fibers, one from either boron fibers or their combinations material may be selected. In the present embodiment, carbon fibers are used, and there are 5 seams and the length when stretched is about 1500 mm, the length when shrunk is about 300 mm, and the maximum diameter is 14 mm. Is about 40 grams.

FIG. 2 is a perspective view of the connecting member, and is a member having a hollow structure for connecting the expandable member toward the both ends of the bow and the butt, as indicated by reference numeral 4 in FIG. In addition, the connecting member is provided with an angle of 160 to 180 degrees in accordance with the hull of the kayak which becomes curved and becomes thinner as it goes toward the bow or the bow, and the elastic member becomes easier as it goes toward the bow or the bow. To be able to approach. Note that the angle of the connecting member may be curved. The material used for the connecting member may be selected from any one of alloy steel obtained by adding chrome, nickel, molybdenum and the like to carbon steel, carbon steel, aluminum and stainless steel. The mass of the connecting member alone is, for example, about 70 grams when using aluminum having a hollow structure with a diameter of about 18 mm and a total length of about 200 mm.

FIG. 3 is a perspective view of the cockpit frame. At least two cockpit frames are arranged as indicated by reference numeral 5 in FIG. 4, and at least five elastic members connected by a connecting member are arranged in the cockpit frame in FIG. The elastic members connected to the connecting member have a structure that can be individually removed, and can be removed from the cockpit frame as shown in FIG. 8 when the entire kayak is stored. As the material used for the cockpit frame, one of carbon steel, alloy steel in which chromium, nickel, molybdenum, etc. are added, carbon steel, aluminum, and stainless can be selected. In addition, the total mass of the combined structure of the cockpit frame made of aluminum having a hollow structure with a total length of about 1000 mm, a diameter of about 24 mm and a thickness of about 2 mm and the connecting portion with the elastic member is about 250 g.
