Abstract

PURPOSE:To ease transportation or storage and to improve maneuverability of a catamaran in which a pair of float body are connected together by beams, by forming each float body with a bag body capable of being folded and by attaching a metal plate to the aft end surface of each float body for holding a rudder. CONSTITUTION:A pair of float body 1 consist of bag bodies, made of waterproof material like rubber, whose insides are filled with compressed air to maintain the shape. Each float body 1 is connected with each other by making the ends of each beam 2 and 3 to penetrate locking pieces 13 provided at both fore & aft and outer & inner sides of each float body 1, so as to have each fload body 1 connected with each other. Sleeves 41 provided at both ends of a connecting rod 42 are made to penetrate beams 2 and 3 which are connected together through a connecting member 4. At the crossing point between the forward sleeve 41 and a connecting rod 42, a mast holder 43, into which a mast 6 is inserted, is fixed. At the aft end of each float body 1, a metal plate 8 is fixed by means of adhesive cloth 81 so that the metal plate 8 holds a rudder plate 9 that is operated by an operating rod 93 via a connecting rod 92.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved IQ for small sailing catamarans.

In the small sailing Kakumaran, where a pair of hulls are connected to each other by a beam, conventionally the beam was attached to the hull and completely fixed, making it easy to install (11). However, there is a problem that it becomes bulky and long when stored during off-season storage.Also, it has been proposed that the beam and the hull be made into a structure that can be disassembled, but apart from this, the hull itself Since the size remains the same, there was a limit to the reduction in bulk.

This invention was made to solve these conventional problems, and it has made the hull of the boat smaller and has TIJ function, making it very convenient for transportation and storage, and also making it possible to control the rudder. 11
It is designed to have 11 functions. That is, in this invention, a pair of hulls are connected to each other by beams at two locations in the front and back, and the beams are connected to each other at the connecting portion side, and each hull is constructed of a bag filled with air to maintain its shape. The mast of the sail is supported on the beam or its connecting member, and the rear end surface of each girder forms a nearly vertical flat surface, and a metal plate is attached to cover the entire surface of the flat surface. (J5 is retained.

An embodiment of the present invention will now be described with reference to FIG. 1.

In FIG. 1, a pair of hulls 1 (connected to each other by beams 2.6 after i i'iFi) are shown.
is made of rubber, plastic, or other waterproof fabric (-6) into a bag body, and is held in a certain shape by filling the inside with air.
1 and the locking pieces 16 on both sides of the beam 2.
．． The end of the filter is passed through the locking piece 1 and the supporting member 1 is inserted.
1 and the support member 11 is placed on the beam 2.1 by the expanding force of the hull 1. Beam 2. The rotor is connected to the hull 1.

The connecting member 4 has a sleeve 41 fixed to both ends of a connecting rod 42, and the beam 2 and the filter pass through the sleeve 41. Also, a mast holder 4 made of pipe material is fixed to the intersection of the sleeve 41 and the connecting rod 42 on the front side, and a mast 6 for the sail 5 is attached to this mast holder 43 from one side.
The lower end of is inserted. Further, a rib 90 is formed to protrude from the lower side thereof, and the center board 10 is held by this. 40 is a rope for adjusting the angle of the center board 10. The centerboard 10 may be attached to the hull 1. A campus 14 is arranged between the hulls 1, and its peripheral edge is connected to the hull 1, beams 2, 3, and connecting member 4 by appropriate means.
4 is shown with a portion cut away.

As shown in FIG. 2, the rear end of the hull 1)
A metal plate 8 made of aluminum or the like is stacked so as to cover the entire surface of the end member 80, and an adhesive cloth 81 (fixed thereon) is attached to the outer periphery of the end member 80. Attach the U-shaped locking piece 95 to the plate 8 with the screw 9.
The rudder plate 9 is rotatably attached around a pin 97 by a locking piece 95 with a locking piece 95. Operating rods 91 are attached to the upper ends of the steering plate 9, and both ends of the operating rods 91 are connected by a connecting rod 92, and an operating rod 9 is connected to the center of the connecting rod 92.

In the above configuration, even though the hull 1 is a bag body, the transom at the rear end is made of a metal plate, so it is possible to attach a rudder plate, and this metal plate Since the rear end surface P is configured to cover the entire surface, it can sufficiently withstand various forces applied from the steering plate.
The rudder plate can be held stably. Also, the overall structure consists of a pair of hulls 1 or beams 2. Since it is firmly connected by the filter and the connecting member 4, it is stably maintained in the state shown in FIG. 1 during use. Bin 97 when not in use
It can be removed by pulling the integrated rudder plate upward, and the other parts can be made into independent parts.Furthermore, the hull 1 has a very compact structure by letting out the air inside. It can be folded into.

As explained above, the present invention provides a catamaran in which a pair of hulls are connected by a beam, in which each hull is configured as a bag body to make it foldable, and the transom of the hull is constructed to be strong so that the rudder can be controlled. It is designed so that the base of the rudder does not touch (it does not affect the driving performance), and is very convenient for transportation, storage, and handling.
