Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to, for example, small electronic equipment,
Regarding portable bags that can safely store equipment and parts that are easily damaged by impacts, such as cameras and their accessories, etc., especially those stored inside the bag. This invention relates to a portable bag that has excellent protection against external impacts and is easy to assemble.

0002

[Prior Art] When carrying equipment that is expensive and vulnerable to shock and vibration, such as small electronic devices, cameras, measurement equipment, etc., it is recommended to use a dedicated carrying bag, case, etc. with a protective structure. It is common. This type of bag generally has a box-shaped bag body such as a rectangular parallelepiped, and the inner walls are lined with cushioning material such as a sponge sheet with appropriate elasticity and rigidity, and the cushioning effect of the cushioning material Protects the protected equipment stored inside from external shocks.

[0003] By the way, it is inevitable that the manufacturing process for bags whose inner walls are lined with cushioning materials such as sponge sheets with sufficient thickness and elasticity will be complicated and require many man-hours. It is. That is, each inner wall is sewn with the sponge sheet sandwiched between the outer skin and the inner skin, but during sewing, a large load is placed on the sewing machine due to the thickness and strength of the sponge sheet, causing malfunction, and the peripheral edge of each inner wall The sewing condition of the parts may deteriorate, and the sewing line may not be in an accurate straight line, resulting in a loss of aesthetic appearance. Also, if you sew a sponge sheet with a thickness and strength that exceeds the load limit that can maintain normal operation of the sewing machine,
Twisting, distortion, wrinkles, etc. are formed on the wall, resulting in poor shape. Furthermore, in the process of interconnecting the inner walls containing the sponge sheets, it is necessary to sew the inner surfaces of the bag.
After sewing the key points on the inner wall with the bag turned inside out,
It will be necessary to put the front and back sides back together again during finishing work, but
At this time, due to the rigidity of the sponge sheet, it is difficult to return the front and back sides of the bag to their original positions. In this way, the conventional bag manufacturing process involves sewing a sponge sheet between the inner and outer skins, sewing the walls together with each wall turned inside out, and then turning the sewn bag on its front side. Since it involves a large number of complicated steps such as the step of returning the product to the original shape and final sewing, it inevitably requires a lot of labor and time, resulting in various problems such as increased manufacturing costs.

[0004] In addition, in the case of a conventional bag in which a sponge sheet is simply interposed between the outer skin and the inner skin as described above, even if a sponge sheet with sufficient hardness is selected, the completed If a large external impact is applied to the bag, it will easily deform, making it impossible to effectively protect the important equipment inside.

[0005] The reason why such a situation occurs is that the strength of the sponge sheet itself is not sufficient, but moreover, the reason why this situation occurs is that the strength of the sponge sheet itself is not sufficient. The main cause can be found to be that there is no special support member to reinforce them.

[0006]

[Purpose of the Invention] The present invention has been made to eliminate the above-mentioned drawbacks, and to improve the quality and productivity of the product by standardizing the parts that make up each part of the bag, and to improve the quality and productivity of the product. The purpose of the present invention is to provide a portable bag that has significantly increased strength and impact resistance, thereby improving the ability to protect protected items stored therein.

[0007]

A side outer skin to which a pocket, a leather strap, and a lid are attached, and a bottom outer skin forming the bottom of the bag are sewn together, and a side inner skin is sewn and connected to the upper end of the side outer skin, and between the inner side skin and the outer skin. A sponge sheet standardized according to the size of each side wall of the bag is sandwiched between molded support connecting members, and the completed side frame is inserted to form the side wall of the bag. There is a bottom plate and a cushion plate, and the inside of the bag is separated by a partition wall with Velcro attached.

[0008] The method for manufacturing a portable bag according to the present invention having such a structure is to first cut fabric to a certain standard to make members such as the inner and outer skins, and then attach Velcro tape to the side of the inner skin facing toward the inside of the bag. At the same time, attaching means such as auxiliary pockets, leather straps, etc. to the outer side skin, and then sewing and connecting the inner side and the upper end of the outer skin.
The body forming step involves joining the lower ends of the side skins and the edges of the bottom skin by sewing, and the assembly of the molded corner reinforcing supports and the side wall frames, in which a sponge sheet is inserted into the corner reinforcing supports to form a reinforcing side wall frame. a step of inserting the side wall frame between the inner and outer skins; a step of inserting a bottom plate to be crimped onto the bottom outer skin to bring together the edges of the side inner skin; and a step of inserting the side wall frame between the inner and outer skins; It consists of a step of installing a fixed bottom plate, an internal packing step of crimping a cushion cover onto the bottom plate and dividing the interior space of the bag with a partition wall, and a lid attaching step of attaching a lid to one side of the side skin. has been done.

Next, a method of manufacturing a portable bag having the above structure will be explained with reference to FIGS. 5 and 6.

First, bag fabric made of leather, resin, etc.
The bottom outer skin 1, side outer skin 2, side inner skin 3, etc. are formed by cutting into a predetermined shape. Next, Velcro tape 11' is attached to the side inner skin 3, and the auxiliary pocket 8 and the leather strap 10 are sewn to the front and side surfaces of the side outer skin 2, and then the bottom outer skin 1 and the side outer skin 2 are sewn vertically. Then, the upper edges of the side outer skin 2 and the side inner skin 3 are sewn together, and the side inner skin 3 is hung inside the side outer skin 2 (Fig. 5 (A)
, Figure 6(A)).

Next, the sponge sheet 5 is connected to the molded corner reinforcing support base 6 to form an annular side wall frame as shown in FIG. It is inserted between the endothelium 3 and the endothelium 3 (FIG. 6(B)).

Next, the bottom plate 13 is crimped so as to cover the lower edges of the outer skin 1 and the side inner skin 3 located inside the bag, and the bottom plate 13 is connected to the bottom outer skin 1 by the fixing means 14, or
Alternatively, after fixing by riveting and laying the cushion cover 15 on the bottom plate 13, the internal space is divided by the partition wall 12 (FIGS. 5(B), 6(C), and 6(C)).

Finally, a lid 9 is attached to the upper rear surface of the side skin 2.
The manufacturing process is completed by fixing the
D) and a portable bag having the structure and shape shown in FIGS. 6(A) to 6(C) is completed.

[0021] If necessary, the auxiliary pocket 8 can be attached to the front, both sides, or the rear of the outer skin 2 by sewing, and the interior of the bag can be partitioned in various ways with the easily removable partition wall 12. .

On the other hand, the shape and size of the bag can be varied, such as large or small, and the bag can also be deformed into a regular hexahedral shape, for example.

[0023] In the present invention, since there is no need to pierce and suture the cushion material such as a sponge sheet with a needle,
As the cushioning material, various materials with excellent strength can be selected. For example, it is possible to assemble a bag using a high-strength cushioning material that is difficult to sew with a conventional sewing machine. Moreover, the completed bag can be sufficiently protected from external forces such as impact due to the elasticity and rigidity of the cushioning material. The objects to be directly sewn are leather, resin, fibers, etc., and it is easy to suppress the occurrence of twists, distortions, wrinkles, etc. during sewing. As a result, deterioration of the appearance can be prevented. Further, since the operation of connecting the bottom outer skin 1, the side outer skin 2, and the side inner skin 3 to each other is performed before the reinforcing side wall is inserted, it is easy to turn the bottom side inside out or turn it back to its original state. The work of suturing the bottom outer skin 1, the bottom plate 13, and the side inner skin 3 can be carried out even after the sides are turned over.

Furthermore, the bag according to the present invention can be used not only for storing and carrying cameras, measuring equipment, etc. as in the above embodiments, but also as a bag for storing and carrying cosmetics, precious metals, etc.

Furthermore, since the portable bag according to the present invention is very easy to assemble, it is possible for the consumer to purchase the component parts individually and assemble the bag himself. For example, the side outer skin 2 and the side inner skin 3 to which the lid 9 is sewn and connected, and the sponge sheet 5
, partition walls 12, etc. are sold separately. Consumers who purchase the bag can also select the specifications and colors that suit their tastes and complete the bag themselves. In this case, costs can be reduced compared to purchasing a finished product.
