Structure for Sport Board

Abstract

An improved structure for a sport board comprises: a first layer, which is a low density foam layer and has a first surface and a second surface; a second layer, which is a hardened layer, a first surface of the second layer being joined the second surface of the first layer; a third layer, which is a low density foam layer, a first surface of the third layer being joined a second surface of the second layer; and a cover layer, which is a waterproof layer, a first surface of the cover layer being completely joined the first surface of the first layer and a second surface of the third layer.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention generally relates to an improved structure for a sport board, more particularly to a sport board structure which is assembled by a hardened layer and a special assembling method.2. Description of the Prior ArtWater sports are always attractive, especially the earth temperature is increasing gradually. Taiwan in the subtropical zone is now approaching 37-38° C. in summer in the recent years, and Europe and North America are sometimes more than 40° C. So that, water sports are more popular than ever, more particularly to the sea sports.Although the sea sports in summer are more year and year, surfing in either Europe or North America is popular all the year as well, therefore the sea sports may not be disappeared due to cold weather. Additionally, following the conditions of water sports in inland lakes and sea activities being increased, the safety to water sport devices or lifesaving devices is relatively prom...

AI Technical Summary

Benefits of technology

The primary objective of the present invention is to provide an improved structure for a sport board so as to figure out the shortcomings of lower production, higher cost, hard quality control, etc. in prior arts.

The secondary objective of the present invention is to provide the improved structure for the sport board so as to figure out the problems of damaging the inside structure of the sport board due to water leaking in prior arts and enhance the strength and stress of the sport board.

Problems solved by technology

As a conclusion based on aforesaid method, there are three shortcomings listed below:(1) The steps of pressing and gluing by hands and keeping pressing for a period of time are obviously increasing manufacturing cost, and the effect of gluing may not be good as well.(2) Machining and grinding may cost a lot.(3) The waterproof rims may be easily leaking water so as to cause low durability and liability.

Another point, when leaking is happening, the whole structure will be collapsed due to that of a foam material.

Therefore, how to figure out such shortcomings is an important issue to the people who are skilled in the art.
