Erectable tent

Abstract

It is an object of the present invention to provide an inexpensive erectable tent having a simple structure in which the covering sheet can easily be removed from the structural framework assembly, and an airtight structure with respect to the surrounding atmosphere and ground surface can also easily be formed, in such a way that the air-tightness required for a hygienic gas treatment using a freshness-preserving gas or the like can easily be obtained. The present invention provides an erectable tent in which a structural framework assembly 3 used to form a chamber space is formed in such a way that structural framework members 1 can be assembled or disassembled via couplings 2, a bag-like inner lining sheet 9 is formed having a ceiling surface inner lining sheet 7 and peripheral surface inner lining sheets 8 that are applied as an inner lining to the inside surface of the structural framework assembly, this bag-like inner lining sheet is engageably and disengageably suspended via suspension fittings 10 from ceiling framework 4 of structural framework assembly 3, the lower open surface of the bottom framework 5 of the structural framework assembly 3 is covered by a ground surface covering sheet 13, the peripheral edge parts of this ground surface covering sheet 13 and the lower edge parts of peripheral surface inner lining sheets 8 are connected, and an entry/exit 14 that can be opened and closed is formed in [one of] peripheral surface inner lining sheets 8.

1 . An erectable tent characterized in that a structural framework assembly used to form a chamber space is formed in such a way that the structural framework can be assembled or disassembled via couplings; an inner lining sheet in the form of a bag is formed having a ceiling surface inner lining sheet and peripheral surface inner lining sheets, which are applied as an inner lining to an inside surface of the structural framework assembly; the bag-like inner lining sheet is suspended via engageable and disengageable suspension fittings from the ceiling framework of the structural framework assembly; a lower open surface of a bottom framework of the structural framework assembly is covered by a ground surface covering sheet; a peripheral edge part of the ground surface covering sheet and a lower edge part of the peripheral surface inner lining sheets are connected; and an entry/exit that can be opened and closed is formed in one of the peripheral surface inner lining sheets.  
   
   
       2 . The erectable tent according to  claim 1 , characterized in that the bag-like inner lining sheet is made of a transparent synthetic resin sheet.  
   
   
       3 . The erectable tent according to  claim 1 , characterized in that a peripheral edge of the ground covering sheet protrudes laterally outward from where the peripheral surface inner lining sheets are joined and forms a flange, the bottom framework of the structural framework assembly being carried on this flange.  
   
   
       4 . The erectable tent according to  claim 1 , characterized in that supporting means for supporting a hygienic gas generating device that is used to subject fresh fruits or fresh vegetables to a hygienic treatment is installed on the ceiling framework of the structural framework assembly.  
   
   
       5 . The erectable tent according to  claim 1 , characterized in that an opening is provided to one of the peripheral surface inner lining sheets that form the bag-like inner lining sheet; a door framework that is integrally fastened to the structural framework assembly is situated in the opening; edges of the opening of the peripheral surface inner lining sheet are caused to adhere tightly to the door framework; and the entry/exit is formed by installing a door that can be opened and closed, and that covers the open surface of the door framework.
