Abstract

PURPOSE:To ensure the longitudinal strength of a hull while assembling constitutionally firmly a plurality of separated parts into a single hull by winding and fastening both broadsides from bow to stern and piercing grooves on the bottom by means of a strong wire to envelope the hull. CONSTITUTION:The central portion 1, stern portion 2 and bow portion 3 of a hull are forced to butt each other on the mutual connecting surfaces 5 through engaging dowels 4 to be fixed laterally. Further, angular ribs 6 provided on both sides of the longitudinal center line of the bottom in each section of the hull are respectively provided with grooves 7 extending longitudinally through the bottom surface of bottom side, and grooves 9 are provided under both broadside ends 8 at bow, central and stern section of the hull. And two wires 10 are respectively stretched fore-and aft in the grooves on both sides of the bottom surface and both broadside ends to be tightened by the use of a turn- buckle 11. Thus, the hull is extremely firmly fixed while being stuck longitudinally to have a longitudinally strong deflection resisting force.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small and convenient boat. Ships, which are originally on the water and carry people for transportation, cannot be scaled down to the necessary size.

However, in recent years, there have been many portable and lightweight boats, such as rubber boats, and there are also boats whose hulls are cut into two halves, with grooves around the entire circumference, and which are fitted together and tightened with bolts; the former are made of cloth-lined rubber. Therefore, the durability is poor, and it is troublesome to prepare a pump to supply air. In the latter case, in order to maintain watertightness and strength at the joints, the structure becomes complicated and the weight increases.
There has long been a need for a structure that is strong and easy to assemble by dividing it into nine parts in order to meet the purpose of carrying.

Here, the inventor has provided a portable assembly type boat of the required small size, which is characterized by strong wires on both sides from the bow to the stern and through grooves on the bottom, so as to wrap around the hull. The purpose is to secure the vertical strength of the hull by tightening the hoop around the tub, and to firmly assemble and configure the multiple parts that can be divided at the same time as one hull.

The structure will be explained according to the drawings. FIG. 1 is an overall perspective assembly view, and FIG. 2 shows the central portion taken along the line A-λ. As shown in both figures, the center part 1, stern part 2, and bow part 6 are as follows.
The mating dowels 4 are used to butt each other at the joint surfaces 5, and the lateral direction is fixed.

Furthermore, there are chevron-shaped ribs 6 provided on both sides of the vertical center of the bottom of each part of the hull.
A groove 7 is passed through the bottom of the ship from the bottom side forward and backward, and grooves 9 are made under both sides 8 of the bow, the center of the hull, and the stern.

For such a hull configuration, if two wires 10 are passed through the grooves on both sides of the bottom and on both sides from the front and back, and the tongue buckles 11 are used to tighten the hull, the hull will be extremely firmly fixed, and at the same time the front and rear This creates a strong vertical drag force, which overcomes the weaknesses common to ships of this type. FIG. 6 shows the state of the wires passed to the hull, with the stern 2 and bow 6 shown in dotted lines at the front and back of the hull center 10, and the wires 10 are attached via tongue buckles 11.

In this configuration, when the wire is loosened and removed, the hull is immediately divided, and as shown in Figure 4, the stern section is stacked inside the center of the hull, and the bow section is stacked inside it like a box. As shown in Fig. 5, only the gunboard ends are exposed and overlapped to form a single unit, making it extremely easy to carry and can be loaded into the rear trunk or loading platform of a relatively small car.

As a result, the conventional methods of mounting these on the roof of a car or towing them with a trailer become unnecessary.

Furthermore, a special watertight structure is provided at the joints of the hull, or the joints are filled with rubber backing and bolted. Fitting type eliminates the need for thick and sturdy walls.

It is extremely easy to match the dowel with the other flat surface.

The hull is strongly held together by two wires, which has a synergistic effect, making it a convenient prefabricated boat that can be used as a fishing boat in fJJ marshes, rivers, shallow waters, emergency rescue boats, etc.

Claims (1)

[Claims] Divide the hull into multiple parts at right angles to the axis, create a groove that penetrates the bottom of each part vertically, make grooves for the same purpose in this part and on both port and starboard sides, and secure them by stringing wire from the bow to the stern. A prefabricated boat.
