Description

  The present invention relates to a soft bag such as a sports bag or a commuter bag having flexibility.

  Conventionally, sports bags and the like are made of a soft material having flexibility, but recently, commuter bags are also made of soft materials on the market.

  However, since the soft type bag (bag) only secures the shape retention by the tension of the flexible fabric, there is a problem that it is easy to lose shape and does not look good.

  As a means to solve the above problem, a three-layer laminated fabric is formed by pressing and heat-molding a three-layer laminated fabric with a synthetic fiber woven fabric on the front, a synthetic tricot fabric on the back, and a urethane foam layer on the middle layer. (For example, Patent Document 1).

  However, there is a problem that when a bag is manufactured by the one means, there is a very high possibility that the cost will be high.

Therefore, the industry that handles bags is looking forward to the development of soft bags that are low in cost and hard to lose shape.
Japanese Patent Laid-Open No. 9-135717 (see FIG. 4)

  Accordingly, an object of the present invention is to provide a soft bag that is low in cost and hardly loses its shape.

(Invention of Claim 1)
In the soft bag of the present invention, a metal wire having elasticity is accommodated in a pie pin sewn at a joint portion between fabrics constituting the bag main body.

(Invention of Claim 2)
The soft bag of the present invention relates to the invention described in claim 1 above, wherein a bag-like portion is formed in the upper region of the fabric of the front and rear surfaces constituting the periphery of the opening of the bag body, and the bag-like portion is elastic A thin plate-like metal plate having the shape is accommodated.

(Invention of Claim 3)
The soft bag according to the present invention relates to the invention according to claim 1 or 2, wherein the metal wire is a coil spring.

(Invention of Claim 4)
The soft bag of the present invention relates to the invention described in claim 2 above, and the bag-like portion is arranged in the upper region of the cloth on the front and rear surfaces.

  The soft bag of the present invention is low in cost and hardly loses its shape.

  Embodiments as the best mode for carrying out the soft bag of the present invention will be described in detail below.

  1 is an external perspective view of a soft bag SB according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view of the soft bag SB, and FIG. 3 is elastic in a pie pin sewn at a joint portion between fabrics. Sectional drawing of the state which has accommodated the metal wire which has is shown.

(About the configuration of this soft bag SB)
As shown in FIG. 1 and FIG. 2, this soft bag SB is of the type used during commuting, and is provided on the bag body B having a lid part b that opens and closes the upper end opening part, and the bag body B. It consists of two handles H, H.

  As shown in FIGS. 1 and 2, the heel body B includes a first fabric 1 comprising a front surface portion 10, a rear surface portion 11 and a bottom surface portion 12, a second fabric 2 forming a left gusset portion, and a right gusset portion. And a third fabric 3 to be formed. As shown in FIG. 1, the left edge of the first fabric 1 and the second fabric 2 are connected to each other, and the right edge of the first fabric 1 and the third fabric 3 are connected to each other. These are attached via so-called pie pins 4.

  Here, as shown in FIG. 2, the entire upper end portion of the front surface portion 10 and the rear surface portion 11 has bag-shaped portions 13 and 14 that are sewn after being bent inward, and the bag-shaped portion. Each of 13 and 14 accommodates a thin metal plate MP (for example, a leaf spring) having elasticity.

  Further, as shown in FIG. 2, fabrics 50 and 51 are arranged on the inner surface side of the front surface portion 10 and the rear surface portion 11, and the front surface portion 10 and the fabric 50, and the front surface portion 11 and the fabric surface 51. The inner pocket IP that can be opened and closed by the fastener F is formed.

  Further, as shown in FIG. 2, the lid portion b is sewn to the upper end portion of the fabric 51, and the free end side of the lid portion b is fastened to the fabric 50 side via a hook 52. By doing so, the upper end opening part of the bag main body B can be closed.

  As shown in FIG. 3, the pie pin 4 is composed of a circular tube portion 40 and pieces 41 and 41 extending from the end edges thereof. Specifically, one piece 41 is a first fabric. 1, the other piece 41 is sewn to the second fabric 2 or the third fabric 3. Here, in this soft bag SB, as shown in FIG. 3, an elastic metal wire S (for example, a small-diameter coil spring) is accommodated in the entire region of the circular tube portion 40 in the pie pin 4.

  In the first embodiment, as shown in FIG. 1, the front surface portion 10 is divided into two horizontally, the two are connected by the pie pins 4, and the metal wire S is accommodated in the missing circular tube portion 40 of the pie pins 4. is there.

(About the excellent action and effect of this soft bag SB)
The soft bag SB can be prevented from being deformed by the elastic return force of the metal wire S in the pie pin 4 and the metal plate MP in the bag-like portions 13 and 14. Specifically, the vertical folding of the heel body B is prevented by the metal wire S, and the lateral folding of the heel body B is prevented by the metal plate MP.

  Moreover, since the metal wire S is accommodated in the pie pin 4 which originally existed or the metal plate MP is only accommodated in the bag-like portions 13 and 14 that can be easily formed, the cost is not increased.

  Therefore, the soft bag SB is very convenient because it is low in cost and hardly loses its shape.

  FIG. 4 is an external perspective view of a sports bag (soft bag) that accommodates a uniform and a tool used for exercise.

  The overall shape of this sports bag is different from that of Example 1, but the basic form as a bag is exactly the same.

  However, in this sports bag, as shown in FIG. 4, the first fabric 1 including the front surface portion 10, the rear surface portion 11, and the bottom surface portion 12, the left and right gusset portions, and the upper surface portion (having the fastener F) are integrated. As shown in the figure, the first fabric 1 and the fabric 6 are sewn through the pie pins 4 in a one-stroke writing state. Note that an elastic metal wire S is accommodated in the cut-off tube portion 40 of the pie pin 4.

  In this sports bag, lateral folding is prevented by the metal wire S extending in the lateral direction in the pie pin 4, and vertical folding is prevented by the metal wire S extending in the longitudinal direction in the pie pin 4.

  Moreover, since the metal wire S is only accommodated in the pie pin 4 that originally existed, the cost does not increase.

  Therefore, this sports bag is low in cost and difficult to lose its shape, which is very convenient.

(Other)
FIG. 5 shows an external perspective view of a soft type travel bag.

  In this travel bag, the pie pin 4 in which the frame portion W formed by the upper surface portion 15, the bottom surface portion 12 and the upper and lower gusset portions 2, 3, and the front surface portion 10 and the rear surface portion 11 accommodate the metal wire S. It is sewn through. Note that an elastic metal wire S is accommodated in the cut-off tube portion 40 of the pie pin 4.

  It is clear that this travel bag has the same effects and advantages as those of Examples 1 and 2.

  In addition, the position which provides the bag-shaped parts 13 and 14 for accommodating the said metal plate MP can be changed suitably.
