## Background
FIELD OF THE INVENTION
The present invention relates to a cushioning material, and particularly to a cushioning material that forms a multilayer structure by a locking and fastening means.
BACKGROUND OF THE INVENTION
Along with the precision trend of technology products, in order to prevent damages caused by impacts during a transportation process of products, many manufacturers and industrialists adopt cushioning materials for preventing impacts during packaging and transportation processes. To further enhance the protection effect, many manufacturers and industrialists adopt cushioning materials that are in multilayer structures, and custom-make corresponding cushioning materials according to patterns of objects to be transported. However, as conventional cushioning materials are made by attaching a plurality of cushioning blocks, extremely precise alignment is required in the attaching process to ensure that the manufactured cushioning material is capable of reliably protecting the transported objects from impacts. As a result, the manufacturing process of the cushioning material is made too complicated.
In addition, after having been manufactured, a current cushioning material is a fixed pattern, which may result in storage difficulties and excessively occupy storage spaces. For example, the Taiwan Patent Publication No. 553185 discloses a design of box frame plates assembled by consecutively stacking hollow plates. The disclosed plate assembly is consisted of stacked frame plates and solid plates. The frame plate has hollow grooves or hollow holes, and holes, openings or grooves are provided at a periphery of the hollow groove or hollow hole. The solid plate is provided with holes, openings or grooves at corresponding positions. When the frame plate and the solid plate are stacked to form the plate assembly, the holes, openings or grooves form a symmetrical relationship for a detachable fastening element to bind, insert, screw or attach to become a box, a carton, a rack or a photo frame. In such method, a plurality of plates need to be individually folded to form the solid plate of a multilayer structure, and the detachable fastening element is then fastened. However, the fastening and alignment of the detachable fastening element may hinder the box frame plate from being readily and quickly assembled.

When the fastening member 2 is installed, the first fastening end 22 is locked and fastened in the first clamping portion 113, and the second fastening end 23 is locked and fastened in the second clamping portion 123. To securely fasten the fastening member 2, the widths of the first fastening end 22 and the second fastening end 23 of the fastening member 2 are greater than the width of the extension section 21, the width of the first clamping portion 113 is greater than the width of the first assembly portion 112 of the first assembly section 11, and the width of the second clamping portion 123 is greater than the second assembly portion 122 of the second assembly section 12. As such, the first fastening end 22 and the second fastening end 23 may be more securely locked and fastened in the first clamping portion 113 and the second clamping portion 123, respectively. Further, according to application requirements, the first groove 111 and the second groove 121 may be disposed at the sides of the first assembly section 11 and the second assembly section 12. Thus, when the first assembly section 11 and the second assembly section 12 are bent towards the connecting section 10, the first groove 111 and the second groove 121 jointly define the accommodating region 13 for accommodating an object.
Referring to FIG. 10, the first assembly section 11 and the second assembly section 12 are disposed at the same side of the connecting section 10. The connecting section 10 includes a fourth bending line 3. When the first assembly section 11 and the second assembly section 12 are respectively bent along the first bending line 16 and the second bending line 17 towards the connecting section 10, the connecting section 10 is further bent along the fourth bending line 3 to cause the first assembly section 11 and the second assembly section 12 to come into contact with each other. Thus, the first assembly portion 112 of the first assembly section 11 and the second assembly portion 122 of the second assembly section 12 jointly form the assembly region 14 for locking and fastening the fastening member 2.
Again referring to FIG. 6 to FIG. 9, the assembly process according to this embodiment is given in detail below. As shown in FIG. 6 and FIG. 7, at the beginning of the assembly process, the cushioning body 1 is in a flat pattern. The user may simultaneously bend the first assembly section 11 and the second assembly section 12, in a way that the first assembly section 11 is bent along the first bending line 16 towards the connecting section 10 to overlap the first assembly section 11 on the connecting section 10, and the second assembly section 12 is bent along the second bending line 17 towards the connecting section 10 to overlap the second assembly section 12 on the connecting section 10. Thus, the first assembly portion 112 and the second assembly portion 122 form the assembly region 14. The user may then lock and fasten the extension section 21 in the assembly region 14 to lock and fasten the first fastening end 22 in the first clamping portion 113 and to lock and fasten the second fastening end 23 in the second clamping portion 123, thereby forming the packaging cushioning material in a multilayer structure.
As shown in FIG. 8, the cushioning body 1 and the fastening member 2 are a formed integral. The cushioning body 1 includes a bridge section 19, which is extended from the connecting section 10 and connected to the fastening member 2. The first assembly section 11 includes a first locking portion 116 connected to the first assembly portion 112, and the second assembly section 12 includes a second locking portion 126 connected to the second assembly portion 122. When the first assembly section 11 and the second assembly section 12 are bent towards the connecting section 10, the fastening member 2 and the bridge section 19 are bent towards the connecting section 10, in a way that the bridge section 19 is locked in the first locking portion 116 and the second locking portion 126, and the fastening member 2 is locked in the assembly region 14, the first clamping portion 113 and the second clamping portion 123. At the beginning of the assembly process, the cushioning body 1 is in a flat pattern. The user may simultaneously bend the first assembly section 11 and the second assembly section 12, in a way that the first assembly section 11 is bent along the first bending line 16 towards the connecting section 10 to overlap the first assembly section 11 on the connecting section 10, and the second assembly section 12 is bent along the second bending line 17 towards the connecting section 10 to overlap the second assembly section 12 on the connecting section. Thus, the first assembly portion 112 and the second assembly portion 122 form the assembly region 14. The user may then bend the bridge section 19 and the fastening member 2 towards the connecting section 10 to lock and fasten the bridge section 19 in the first locking portion 116 and the second locking portion 126, and to lock and fasten the second fastening end 23 in the second clamping portion 123, thereby forming the packaging cushioning material in a multilayer structure.
As shown in FIG. 9, when the cushioning body 1 is being manufactured, a cutting device is placed on the connecting section 10 to cut out a contour of the fastening member 2, and one edge between the fastening member 2 and the connecting section 10 is designed as semi-detached to produce a third bending line 18. The fastening member 2 is allowed to bend along the third bending line 18 to overlap on the connecting section 10. Further, the connecting section 10 is formed at the position of the fastening member 2 to form a storage region 15, which may store the fastening member 2 when the fastening member 2 is not in use. At the beginning of the assembly process, the cushioning body 1 is in a flat pattern. The user may first bend the fastening member 2 along the third bending line 18 to overlap the fastening member 2 on the connecting section 10. The user may then simultaneously bend the first assembly section 11 and the second assembly section 12, in a way that the first assembly section 11 is bent along the first bending line 16 towards the connecting section 10 to overlap the first assembly section 11 on the connecting section 10, and the second assembly section 12 is bent along the second bending line 17 towards the connecting section 10 to overlap the second assembly section 12 on the connecting section 10. In the overlapping process, the user may eventually lock and fasten the first assembly portion 112, the first clamping portion 113, the second assembly portion 122 and the second clamping portion 123 in the fastening member 2, thereby forming the packaging cushioning material having a multilayer structure.
