Bamboo zephyr board

Abstract

Two types of synthetic resin are used with zephyrs 2 made from a wide range of bamboo canes from undried to dried. An appropriate amount of special thread 4 comprising a core thread 5 having a high melting point and a core-thread covering skin 6 having a low melting point are added to the zephyrs and kneaded together. When molding the kneaded material, it is heated to the temperature at which the skin starts to melt and pressed. Then the skin works as a binder that binds the zephyrs and the core thread. The core thread supplements the strength and the flexibility of the bamboo zephyr board.

1 . A bamboo zephyr board comprising zephyrs taken from a range of undried to near undried bamboo canes of an appropriate length, 
 said zephyrs being kneaded and pressed while being heated at a temperature at which vascular bundle ingredients contained in bamboo ooze out to the surface,    said extract of the bamboo being used as a binder that binds the zephyrs,    thereby said zephyrs are formed into a board of a certain shape equipped with an infinite number of gaps inside.    
     
     
         2 . A bamboo zephyr board comprising zephyrs taken from a range of undried to dried bamboo canes of an appropriate length, 
 said zephyrs being kneaded after being added with an appropriate amount of synthetic resin fiber thread that melts at a desired heating temperature,    said molten thread being used as a binder that binds the zephyrs,    thereby said zephyrs and molten thread are pressed and formed into a board of a certain shape equipped with an infinite number of gaps inside.    
     
     
         3 . A bamboo zephyr board according to    claim 2   , wherein the synthetic resin fiber thread that melts at a desired temperature is a special thread comprising a core thread made of synthetic resin of a high melting point and an external skin, which covers the periphery of the core thread, made of synthetic resin of a low melting point, and when the synthetic resin fiber thread is heated to a temperature at which the skin melts, the molten skin works as a binder that glues the zephyrs and the core thread work as a supplemental material that provides strength and flexibility to the bamboo zephyr board.  
     
     
         4 . A bamboo zephyr board comprising zephyrs and chips taken from a range of undried to near undried bamboo, 
 said zephyrs and chips being kneaded together with an adhesive and pressed while being heated,    said zephyrs, chips and adhesive are formed into a board of a certain shape equipped with an infinite number of gaps inside.    
     
     
         5 . A bamboo zephyr board according to    claim 4   , therein the chips are taken from crushed bamboo leaves and branches.  
     
     
         6 . A bamboo zephyr board according to    claim 1   , wherein a water-holding powder is added.  
     
     
         7 . A bamboo zephyr board according to    claim 1   , wherein when the zephyrs are formed into a board of a certain shape, a multitude of dimples or through holes are formed simultaneously on the up side and down side of the zephyr board.  
     
     
         8 . A bamboo zephyr board according to    claim 1   , wherein diatomaceous earth is applied to the surface thereof.  
     
     
         9 . A bamboo zephyr board according to    claim 1   , wherein shell powder is applied to the surface thereof.
