Foldable tent frame

Abstract

The present invention relates to a foldable tent frame in which a connection frame connected to a column is minimized, and a fabrication is simple and easy, and a fabrication cost is largely decreased, and an economical fabrication is achieved, and a cut-away groove is formed in an engaging part of one side of the top connection part. A rotation protrusion of a rotation part is engaged to the cut-away groove for thereby achieving an easier installation of the rotation part. The rotation protrusion of the rotation part is rotated along the surface of the cut-away groove based on a stable and free rotation, so that it is possible to achieve an easier folding operation of the tent.

What is claimed is:  
     
         1 . In an assembling type tent frame, a foldable tent frame, comprising: 
 a slide connection part  20  engaged to a top connection part  10  engaged to the upper ends of four columns slidably at its lower side;    lateral upper and lower connection parts  25   a  and  25   b  engaged in such a manner that a lateral connection frame  70  engaged in a shape of scissors is folded with respect to the top connection part  10  and the slide connection part  20 ;    an upper connection part  30   a  in which a main connection frame  80  is engaged, and an end portion of the same is engaged thereto in such a manner that the slide connection part  20  and the lateral lower connection part  25   b  are symmetrical from each other;    a support frame  40  fixedly installed to support the main connection frame  80  based on the top connection part  10  and the lateral upper connection part  25   a;      a connection frame  50  installed at one surface of the support frame  40 ; and    an assistant frame  60  of which one end is engaged to the connection frame  50 , and the other end is engaged to a lower connection part  30   b.      
     
     
         2 . The frame of  claim 1 , wherein said top connection part  10  includes: 
 an engaging piece  12  having one side engaging piece  12   a  having a semi-circular cut-away groove  11  in one surface of the same, and other side engaging piece  12   b  having a screw engaging hole  13  at the other side surface of the same; and  
 a rotation part  16  in which a circular rotation protrusion  16   b  engaged to the cut-away groove  11  of the one side engaging piece  12   a  is formed at one side of the same, and a screw engaging hole  15  is provided at the center of the rotation protrusion  16   b , wherein a screw  17  is engaged to the screw engaging hole  15  of the rotation part  16  for thereby being engaged to the other side engaging piece  12   b.    
 
     
     
         3 . The frame of  claim 2 , wherein a groove  13   a  is formed at the center of the other side engaging piece  12   b  of the engaging piece  12 , and a rotation protrusion  16   c  engaged to the groove  13   a  is formed at the other side of the rotation part  16 .
