Folding frame for a case

Abstract

A folding frame structure, wherein a folding structure includes two movable binded members and a fixing clasp member. Two ends of the two movable binded members are respectively affixed to edges of a fixed supporting board and a movable supporting board, and two fastening members are respectively affixed to movable ends of two of the movable supporting boards. After joining together the two fastening members by a mutually embedding method, a fastening catch then securely clasps together the two fastening members. The present invention not only increases convenience when assembling the case, moreover, it effectively reduces the dimensions of the case after folding to facilitate storing away.

1 . A folding frame structure, comprising a plurality of fixed supporting boards, movable supporting boards, folding structures and fastening members, and characterized in that: 
 two ends of the folding structure are respectively attached to ends of the fixed supporting board and the movable supporting board, the folding structure comprises two movable binded members and a fixing clasp member, wherein side edges of the two movable binded members are provided with reciprocal pairing serrated block members, which after reciprocally inter-inserting defines a pivot connection therebetween, another side edge of one of the movable binded members is provided with an inverted U-shaped clip portion and a plurality of through holes, two protruding pieces respectively inwardly protrude from inner sides of the clip portion, which respectively clip within corresponding grooves of the fixing clasp member and move therewithin, the through holes are used for insert pieces that protrude from the fixing clasp member to insert therein;    a side edge of one of the fastening members is provided with a protruding mounting slot and a plurality of insert slots, an opening is defined center of the mounting slot, and outer edges of the mounting slot are provided with a plurality of locating clasps, and a fastening catch is disposed within the mounting slot; an embedding groove is defined center of an edge of the other fastening member corresponding to position of the mounting slot of the other fastening member, and peripheral edges of the embedding groove are provided with locating holes and fastening holes corresponding to the locating clasps and catches of the fastening catch respectively; upper and lower sides of the embedding groove are respectively provided with insert pieces.    
   
   
       2 . The folding frame structure according to  claim 1 , wherein catches configured on a front end of the fastening catch protrude out from the mounting slot when inserted therein, and a rear end of the fastening catch is provided with an elastic member, moreover, a circular hole is defined center of the fastening catch, an inner side edge of which is provided with a clasp member that protrudes from the plane of the fastening catch, which is used to securely clip the fastening catch within the opening of the mounting slot.  
   
   
       3 . The folding frame structure according to  claim 1 , wherein the fastening members are respectively affixed to movable ends of the movable supporting boards by means of an integrated method.  
   
   
       4 . The folding frame structure according to  claim 1 , wherein the fastening members are respectively affixed to movable ends of the movable supporting boards by means of an insert fixing method.
