Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a case having a configuration in which an edge frame is attached to the opening edges of a plurality of case portions that form a case body.

[0002]

[Prior art]

 A conventional case having a certain degree of impact resistance is of a type in which a main body processed by vacuum forming or thermoforming and a lid are opened and closed by a fastener.

In the case of manufacturing this type of case, conventionally, a fastener and a splicing cloth are sewn together, the thread is cut, a double-sided adhesive tape is attached to a molding (edge frame), a double-sided adhesive tape is attached to a main body and a lid, and a molding is used. A number of steps were required, such as attaching the main body and lid, and sewing the fastener and mole together. For this reason, one stitcher and several assistants had to be arranged, which resulted in a high cost.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and its problem is to enable the step of fitting the case constituent member and the molding, that is, the edge frame, and joining them in a temporarily fixed state. The aim is to significantly simplify man-hours and reduce product costs.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a case part by a molded product having a three-dimensional structure, and makes the edge of the part from which the edge is removed the opening edge, and the edge frame follows the opening edge of the case part. It is formed into a substantially L-shaped cross section composed of an outer portion and an inner portion that faces inward, and the opening edge of the case portion is applied to the outer portion, and by means of fastening means such as sewing. An edge frame is fixed to the case part, and a hinge member made separately is attached to the edge frame so that the hinge can be opened and closed, and the opening and closing can be locked by a locking means provided at a portion other than the hinge.

[0006]

[Embodiment of the invention]

 The lockable case according to the present invention has a configuration in which edge frames 15 and 16 are attached to the opening edges 13 and 14 of a plurality of case portions 11 and 12 that form the case 10.

The case parts 11 and 12 are molded products having a three-dimensional structure. As the material, for example, a cloth material, a laminated product, leather or the like can be used, which is processed and formed by means of vacuum forming, pressure forming, press working, hot drawing or the like. Unnecessary flange-shaped portions of the case portions 11 and 12 are cut, and the edges thereof become the opening edges 13 and 14. For the case portions 11 and 12, as in the example shown in detail in FIG. 2, a member formed by molding using a material in which the skin materials 18 and 19 are laminated on both surfaces of the elastic core material 17 may be used. However, by removing the extra edge 20 from the molded member, a removal processing portion 21 such as a cut end appears.

Edge frames 15 and 16 are attached to the opening edges 13 and 14 of the case portions 11 and 12, respectively. Each of the edge frames 15 and 16 is constituted by an outer portion 22 along the opening edges 13 and 14 and an inner portion 23 facing inwardly, and has a substantially L-shaped cross section. See FIG. The illustrated edge frames 15 and 16 are formed in the same shape as the shape of the opening edges 13 and 14, and the opening edges 13 and 14 of the case portions 11 and 12 are fitted into the L-shaped inner corner 24. Reference numeral 25 denotes a recess formed in the outer portion 22.

In order to connect the case portions 11 and 12 and the edge frames 15 and 16, the opening edges 13 and 14 are applied to the inner corner portions 24 of the edge frames 15 and 16, and both are fixed by a fastening means 26 such as sewing. Can be fixed. For fixing, appropriate means such as ultrasonic bonding, bonding with an adhesive, fitting and the like can be used in addition to the sewn bond as illustrated. In the case of sewing, it is convenient in terms of work to secure the contact portions between the case portions 11 and 12 and the edge frames 15 and 16 with a temporary fixing means such as a double-sided adhesive tape. The recess 25 is a portion into which a sewing thread is inserted when sewing.

A hinge member 27, which is manufactured separately, is attached to the edge frames 15 and 16 integrated in this way so that the case portions 11 and 12 can be hingedly opened and closed. The method of attachment is arbitrary, but in the example shown in the figure, a part 28 thereof is fitted into and fixed to the recess 25. The fixing can be performed by adhesion with an adhesive, ultrasonic adhesion, or suturing by sewing. When the case uses the inner case 30, it is easy to protect and arrange the stored items and improve the quality and function. At that time, a part 29 such as an edge of the inner case 30 can be fixed between the case parts 11 and 12 and the edge frames 15 and 16 by fitting or bonding.

The edge frames 15 and 16 have a lock means 31 at a portion other than the portion where the hinge 27 is attached, and can lock the hinge opening and closing of the case. The locking means 31 is composed of, for example, a hook 32 and a hooking portion 33, and is preformed on the edge frames 15 and 16.

[0012]

[Effect of the invention]

 Since the present invention is configured and operates as described above, it is possible to temporarily fix the case part by fitting the edge frame to the case part, and then to join the case part and the edge frame in that state. This has the effect of significantly simplifying and reducing the cost. Such a case of the present invention is suitable for cases of glasses, cameras, VTR cameras, mobile phones, glass products, precious metals, watches and other precision instruments.
