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.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a collapsible frame for a case, which is stored away using a multistage folding method. Moreover, a fastening structure that can be quickly clasped together for securing the frame structure increases convenience when assembling the case, and more effectively reduces the dimensions of the case after folding to facilitate storing away. [0003] (b) Description of the Prior Art [0004] Referring to FIG. 1, which shows a conventional case a as seen on the market, the majority of which have a frame structure a2 disposed within an outer casing a1. The frame structure a2 is used to support the outer casing a1, thereby forming a holding space a3 for a user to place articles therein. Although the conventional case a is extremely convenient, the inability to reduce the dimensions of the frame structure a2 when not in use is a cause for frustration in storing away the oversized case a.

AI Technical Summary

Benefits of technology

[0006] A primary object of the present invention is to provide a folding frame structure that can be used in a general case, which not only more effectively reduces dimensions of the case when storing away but also eliminates concern about weakness in the supporting strength when in use.

[0007] Another object of the present invention is to provide fastening members having simple structure and that facilitate convenient assembly of the folding frame structure.

[0009] According to the aforementioned structure, when using the folding structure, the block members of the movable binded members are first mutually clipped together to fix position of the folding structure, then the fixing clasp member is simultaneously rotated and translated to insert the insert pieces of the fixing clasp member into the through holes of the movable binded member. Furthermore, the two corresponding fastening members are mutually clasped together, and the catches at the front end of the fastening clasp clip within the fastening holes of the embedding groove, thereby rigidly joining together the folding structure and the fastening members to form an integrated body. Moreover, each linking portion has a clasp or clip fastening structure, thereby eliminating concern about weakness in the supporting strength when in use. When storing away the folding structure, the fastening catch is shifted away from its fastening within the embedding groove to separate the catches at the front end of the fastening catch from the fastening holes. The movable binded member and the fixing clasp member are then pulled open and the fixing clasp member rotated. The two movable binded members are also rotated, thereby moving the movable supporting board towards the fixed supporting board, thus realizing multistage folding of the folding structure, which effectively reduces dimensions of the case for storing away. Furthermore, after a fastening catch is inserted within an opening defined center of the mounting slot, a clasp member of the fastening catch is used to clasp within an inner side of the opening of the mounting slot, thereby securely clasping together the fastening structure. Moreover, a rear end of the fastening catch is configured with an elastic member, which apart from providing restoring elasticity when pressing the fastening catch disposed within the fastening member, also provides a force for clasping the clasp member within the opening of the mounting slot. According to the aforementioned configuration, simplicity of the folding frame structure of the present invention facilitates both convenient assembly and use.

Problems solved by technology

Although the conventional case a is extremely convenient, the inability to reduce the dimensions of the frame structure a2 when not in use is a cause for frustration in storing away the oversized case a. Referring to FIG. 2, which shows a foldaway case a that has appeared on the market because of the aforementioned shortcoming in the conventional case.

Although the frame structure a2 improves achieving targeted reduction in the dimensions of the case a, in practical use, the problem of the curved corners of the frame structure a2 having insufficient supporting strength is still present, moreover, assembly is inconvenient.
