Heat insulating storage, voyage data recording unit and voyage data recording apparatus

Abstract

This disclosure provides a heat insulating storage, which includes a first heat insulating member arranged outside an accommodating space and having a heat contraction property and a second heat insulating member for protecting the first heat insulating member from a heat and having a heat expansion property.

1 . A heat insulating storage, comprising:
 a first heat insulating member arranged outside an accommodating space and having a heat contraction property; and   a second heat insulating member for protecting the first heat insulating member from a heat and having a heat expansion property.   
     
     
         2 . The heat insulating storage of  claim 1 , further comprising an accommodating container formed with the accommodating space therein. 
     
     
         3 . The heat insulating storage of any one of  claim 1  or  2 , wherein a temperature of the second heat insulating member when it starts to expand is below or substantially the same as a temperature of the first heat insulating member when it starts to contract. 
     
     
         4 . The heat insulating storage of  claim 1 , wherein the second heat insulating member has a heat resistant property in addition to the heat insulating property. 
     
     
         5 . The heat insulating storage of  claim 1 , wherein the first heat insulating member includes a plurality of first heat insulating sub members. 
     
     
         6 . The heat insulating storage of  claim 5 , wherein one or more of the first heat insulating sub members are arranged to be adjacent on the outside to the rest of the one or more first heat insulating sub members. 
     
     
         7 . The heat insulating storage of  claim 6 , wherein the second heat insulating member is arranged outside the first heat insulating member. 
     
     
         8 . The heat insulating storage of  claim 7 , wherein a hollow space is formed in the first heat insulating sub member and at least a part of the hollow space serves as the accommodating space. 
     
     
         9 . The heat insulating storage of  claim 7  or  8 , wherein in the first heat insulating member, the first heat insulating sub members are stacked on top of another, and one or more parts joining the adjacently stacked first heat insulating sub members on the outside do not overlap with one or more parts joining the adjacently stacked first heat insulating sub members on the inner side. 
     
     
         10 . A voyage data recording unit, comprising:
 the heat insulating storage of  claim 1 ; and   a storing device for storing voyage data, the storing device being accommodated within the accommodating space.   
     
     
         11 . A voyage data recording apparatus, comprising:
 the voyage data recording unit of  claim 10 ; and   a voyage data collecting unit for receiving voyage data from a ship instrument and transmitting the voyage data to the voyage data recording unit.   
     
     
         12 . A heat insulating storage, comprising:
 a first heat insulating member having a heat contraction property; and   a second heat insulating member arranged at a position that is outside an accommodating space and on an inner side of the first heat insulating member, and having a heat expansion property.   
     
     
         13 . The heat insulating storage of  claim 12 , wherein a temperature of the second heat insulating member when it starts to expand is below or substantially the same as a temperature of the first heat insulating member when it starts to contract.
