JPH0810546Y2 - Air cushion boat skirt - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a skirt detachably attached to an air cushion boat.

<Prior Art and its Problems> Conventionally, this kind of material has been formed from a rubber-coated cloth on one side or a single resin-based material.

However, this type of skirt has severe ground wear and poor durability, and it is monochromatic and has no decorative effect, and although it is required to have slipperiness, it has poor slippage during running, The speed was hard.

<Means for Solving the Problem> The present invention has been made in view of such circumstances, and the means is to construct the skirt body by separate rubberized cloths for the ground side and the hull side, and the ground side has both sides. The hull side is a rubber-lined cloth, and the hull side is formed with a single-sided rubber-lined cloth, and a surface treatment layer made of a mixed solution of urethane and silicone is applied to the grounding surface to form a surface coating layer.

<Operation> The grounding side and the hull side can be colored differently, and the wearability on the grounding side is improved, and the treatment with the surface treatment agent imparts lubricity and wearability.

<Embodiment> An example of the embodiment of the present invention will be described with reference to the drawings for a bag type, but it is not limited to this, and it goes without saying that a finger type is also applicable.

The air cushion boat main body A has a form and structure well known in the technical field of this kind, and a propeller is rotated by an engine mounted on the rear portion of the boat body a to generate wind, and a part of the air cushion boat body A is placed under the boat body a. From the inside to the inside of the skirt body b, and is blown to the surface of the skirt body or the surface of the water to float, and the remaining wind is sent backward to travel as a propulsive force.

The skirt body b has a grounding side 1 and a hull side 2 made of different rubberized cloths, and chloroprene rubber (CR) or chlorosulfonated polyethylene (CSM) on one or both sides of a nylon base cloth.
It is made of so-called rubberized cloth coated or topped with synthetic rubber such as, and has a well-known shape according to the size and shape of the hull, with the base cloth side or the rubber side as the surface on the outer peripheral edge of the lower surface of the hull a. The fastener 3 is detachably attached, and has a well-known form in which a large number of blowing holes (not shown) are formed on the inner peripheral surface and a drainage port (not shown) is opened on the bottom surface. The surface coating layer 4 is provided by applying a surface treatment agent on the surface.

The ground-side rubberized cloth 1 has both front and back sides of the base cloth having rubber surfaces, and chlorosulfonated polyethylene is used from the viewpoint of maintaining durability, a rubber sheet is attached to the front side and a paste-like side is attached to the back side. It is a coated material, and a reinforcement cloth is attached around the blowout hole. In order to reduce the weight of the hull side 2, only one side of the base cloth has a chloroprene rubber surface. The grounding side 1 and the hull side 2 are joined together with an adhesive, sewing or both.

The surface treatment agent is composed of a urethane-silicone copolymer resin liquid in which urethane and silicone are mixed, and when applying to the skirt body b, a surface treatment agent is applied to the ground side surface, A liquid prepared by mixing about 5% of a curing agent is applied to the mixed liquid and baked at a temperature of 70 to 100 ° C. for 30 to 60 minutes to form a surface coating layer 4. Although the surface coating layer 4 is formed on the entire outer surface of the skirt body b on the grounding side 1 in the drawing, it may be applied on a portion of a predetermined width to be grounded, or even if the entire surface is partially coated according to the grounding width. , The lower half can also be arbitrarily selected.

<Effect> In the present invention, the skirt body is composed of separate rubberized cloths for the grounding side and the hull side, and the grounding side is formed with a double-sided rubberized cloth and the hull side is formed with a single-sided rubberized cloth, and Since a surface coating layer is formed by applying a mixed solution of urethane, silicone and silicone, wear resistance on the ground side is improved and durability is achieved, and the ground side and the hull side have different colors. By providing the above, it is possible to provide a product that has a decorative effect and that the slipperiness of the ground contact portion is increased, and that the running performance is good and the speed can be increased.

[Brief description of drawings]

The drawings show an example of a skirt of the air cushion boat of the present invention. Fig. 1 is a perspective view of the skirt mounted on the hull, Fig. 2 is a partially cutaway sectional view, and Fig. 3 is an enlarged view of essential parts. It is a sectional view, in which b is the skirt body, 1 is the ground side rubberized cloth,
2 is a rubber-coated cloth on the hull side.
