Description

  The present invention relates to a school bag, and more particularly to a school bag that allows an arbitrary design to be drawn on a large gusset constituting a main body.

  As is well known, a shoulder bag 31 such as a school bag represented by a school bag generally has a bottom plate 32 and a large gusset 33 connected to both ends of the bottom plate 32 in the upward direction as shown in FIG. A back plate 35 is attached to the back side of the body portion 34, and a large partition plate 36 is attached to the front side of the body portion 34. A main body portion having a main storage portion having an upper portion as an opening is configured. In addition, a pair of shoulder belts 37 is attached to the back plate 35, and a lid 38 is attached to the main body portion so as to be able to open and close the opening of the main body portion, thereby constituting the whole.

  By the way, the body portion 34 in the school bag is generally formed by bending a flat plate material as shown in FIG. 5 so that the bottom plate 32 and the large gusset 33 are integrated as shown in FIG. However, the body portion 34 is configured by sewing a lining 39 and a surface material 40 having a shape and dimension substantially the same as the lining 39. When the sewing is performed, the core material 41 is used and an arbitrary thread is sewn. It is common practice to draw designs.

  For example, in the school bag 31 shown in FIG. 4, a ginkgo design is drawn on the large gusset 33, but when a ginkgo design is drawn on the large gusset 33 in this way, as shown in FIG. A core material 41 having the shape of a ginkgo is pasted together, and further, a surface material 40 is pasted to the lining 39 with the core material 41 interposed therebetween.

  Then, the outer fabric 40 and the lining 39 are stitched together along the outline of the core material 41 having the shape of the ginkgo, and as a result, as shown in FIG. It becomes possible to draw the design.

  Therefore, according to such a method, it is possible to draw various designs on the trunk by using a core material having a desired shape.

  However, in the method in which the core material having a desired shape is interposed between the outer material and the lining material and the core material is sewn along the contour of the core material, a core material having a desired shape has to be prepared in advance. It will be fixed. For this reason, in the conventional school bag, there are few kinds of designs drawn on the large gusset, and the choice range is narrow for the purchaser.

  Therefore, the present invention has an object to provide a school bag that allows a variety of designs to be drawn with an increased degree of freedom in design to draw on a large gusset.

The school bag of the present invention

  And the said trunk | drum is comprised by stitching together the lining, the core material piled up on this lining material, and the outer material piled up on this core material, and the shape of the outer material, the core material, and the lining material are substantially equivalent. The size is formed, and when sewing, an arbitrary design is drawn with a sewing thread.

  Here, a reinforcing material may be interposed between the lining and the core material, or between the core material and the outer material at both ends of the trunk portion, and thereby the upper portion of the large gusset can be reinforced.

  An embodiment of the school bag of the present embodiment will be described. FIG. 1 is a schematic perspective view of the school bag of the present embodiment. In the figure, 1 is the school bag of the present embodiment.

  And the school bag of a present Example has the bottomed box-shaped main-body part which opened the upper part like the school bag generally used, and has a textbook etc. inside this main-body part. It can be accommodated.

  That is, in FIG. 1, reference numeral 7 denotes a main body portion. The main body portion 7 includes a substantially rectangular flat plate-like bottom plate 2 and a pair of upper and lower ends that are continuous with each other in the longitudinal direction of the bottom plate 2. It has a body 4 composed of a large gusset 3. Further, a back plate 5 is attached to the back side of the body portion 4, and a large partition plate 6 is attached to the front side of the body portion 4, thereby constituting a main body portion 7.

  Further, a middle gusset portion 9 having a bottom portion is attached to the front side of the large partition plate 6, and a middle partition plate 10 is attached to the front side of the middle gusset portion 9, whereby the front side of the main body portion 7. Is provided with a front pocket portion 11 for accommodating small articles, and a small pocket portion 12 is attached to the front side of the front pocket 11.

  Next, one side portion of a lid 8 is attached to the upper portion of the back plate 5, and the lid 8 has a length dimension capable of covering at least the upper opening of the main body portion 7, Thereby, the upper opening of the main body 7 can be opened and closed by the lid 8.

Yes.

  Next, the trunk 4 constituting the main body 7 will be described. FIG. 2 is a diagram showing a plan view of the trunk 4. In this embodiment, the trunk 4 is similar to the conventional school bag described above. 2 is formed by bending a flat material as shown in FIG. 2 into a form in which large gussets 3 are connected to both ends of the bottom plate 2 (see FIG. 6).

  Here, the structure of the body portion 4 will be described. FIG. 3 is an exploded perspective view of the body portion 4 in the present embodiment. In the present embodiment, the body portion 4 includes a lining 401, a core material 403, The lining 401, the core material 403, and the outer surface 404 have substantially the same shape and dimensions.

  That is, in FIG. 3, a core material 403 having substantially the same shape and dimensions as the lining 401 is overlaid on the upper surface of the flat lining 401, and the lining 401 and the upper surface of the core 403 are overlapped with each other. A surface material 404 having substantially the same shape and dimensions is overlapped, and the body portion 4 is formed by sewing the laminated backing material 401, core material 402 and surface material 404 together by sewing.

  When the lining 401, the core material 403, and the outer material 404 are sewed, in this embodiment, as shown in FIG. 2, an arbitrary design is drawn with a sewing thread. .

  That is, when a design is drawn by sewing along the outline of the core material using a core material that has a shape that matches the design to be drawn like the conventional school bag described above, the design is limited by the core material. In other words, the design without the core material cannot be drawn, and thus the degree of freedom of design is lost. However, in this embodiment, the core material 403 has substantially the same shape and dimension as the lining 401. The sewing can be performed freely, and it is possible to sew while drawing an arbitrary design. Therefore, in the school bag of the present invention, it is possible to obtain large gussets with various designs.

The reinforcing material 402 is attached to both end portions of the upper surface of the lining 401, thereby reinforcing the upper end portion of the large gusset 3. However, the reinforcing material 402 is not necessarily required, and may not be provided. In the case where it is provided, the reinforcing material 402 may be disposed between the outer material 404 and the core material 403.

  In this embodiment, the lining 401 and the reinforcing material 402 are formed using a synthetic resin, the core material 403 is formed using a hard sponge, and the outer material 404 is formed using artificial leather. The material is not particularly limited.

  Next, the operation of the school bag of the present embodiment configured as described above will be described. The body portion 4 in the present embodiment has a shape and dimension substantially the same as those of the lining 401 or the outer surface 404 between the lining 401 and the outer surface 404. When the core material 403 is interposed and these are sewn by sewing, an arbitrary design is drawn with a sewing thread. Therefore, unlike the conventional body that uses a core material shaped to the design to draw and sew along the outline of this core material, it is possible to freely set the design to draw on the large gusset, It is possible to provide a large gusset of various designs, and it is also possible to widen the choice of preschool children and their relatives.

  In the above description, the design drawn on the large gusset is a combination of a plurality of semicircular shapes, but the present invention is characterized by the fact that various designs can be drawn on the large gusset. The design drawn on the large gusset is not limited to the pattern described above.

  The school bag of the present invention has a core material that makes up the torso and has the same shape and dimensions as the lining or outer material, so that it is possible to draw a free design when sewing, so the design can be drawn with sewing threads.
