Description

  The present invention relates to a travel bag such as a suitcase or a carry bag, and particularly to a bag provided with a theft prevention function on a fastener that opens and closes a main body and a lid.

  In travel bags such as suitcases and carry bags, soft case bags are often used as the exterior as a surface fabric made of a flexible sheet material such as fabric or leather. This type of bag is composed of a substantially rectangular parallelepiped main body and a lid that covers an opening for loading and unloading provided on one surface of the bag, and fasteners are used to open and close the main body and the lid. This fastener is also called a slide fastener or zipper, and an element (service tooth) made of metal or plastic is attached to a tape such as cloth, and each element attached to two tapes is attached to a jig called a slider. Opening and closing is performed by meshing or disengaging.

  Opening and closing the lid with a fastener is easy and convenient, but even if the slider is moved to the closed end and the element is engaged, the slider is locked to the closed end and the heel is sealed, the element part will be closed. If you apply force by strongly pressing a sharp tool (such as a screwdriver or ballpoint pen), the elements will disengage, the fastener will be unsealed, the lid can be opened, and the stored luggage will be stolen There are disadvantages such as.

  In addition, to attach the fastener to the peripheral part of the main body or lid, it is attached by sewing together the ends of the fastener tape, the front fabric, and the back fabric, but generally this edge (sewing allowance) is trimmed. It is covered with tape, trimmed, and put together in style. However, as the opening and closing of the fastener is repeated, the slider and the edging tape come into contact with each other many times, and the edging tape eventually wears out.

  On the other hand, in order to prevent the meshing of the element, which is a drawback of the fastener, from being easily removed and entering the inside of the collar, an overhang is provided on one side of the fastener, and a groove is provided on the other side. As a structure in which the projecting portion and the groove portion engage when the fastener is closed, a hook (see Patent Document 1) that prevents the fastener from entering even if the fastener is pry open, or a hard member is provided in the vicinity of the fastener. A suitcase (see Patent Document 2) has been proposed. However, in the former case, when closing with a fastener, it is necessary to match the overhanging portion with the groove portion, which is troublesome and time-consuming to open and close. It is composed of a hard member, and it is necessary to devise the hinge for opening and closing, and the shape of the heel is limited. Even in the bag shown in the latter, the shape of the opening is limited by a hard member provided close to the fastener. Therefore, even if the hard member extends the edge of the shell constituting the ridge or is formed separately, there is no degree of freedom in the shape of the opening and the soft case type Not suitable for moths.

  Patent Document 3 has a structure in which left and right bulging portions are provided close to the left and right elements, and the left and right bulging portions are close to each other inside the fastener when the elements are engaged and the fastener is closed. Fasteners are shown. In this fastener, the opening and closing of the fastener can be smoothly performed due to the proximity of the bulging portion, and while maintaining the shape of the storage opening and providing waterproofness, it is possible to prevent the above-mentioned fastener from being forcibly opened. It will not be.

The thickness of each of the pair of strip-shaped piece portions is not particularly limited, but is preferably 0.15 to 1.0 mm in view of the balance between easy stitching work and durability against contact with the slider.

  2 and 3 are an external perspective view (upper left) of an embodiment applied to a carry bag and a sectional perspective explanatory view (lower right) of a fastener mounting structure taken along line AA of the perspective view. In the embodiment shown in FIG. 2, the carry bag 20 has an example in which a lid 21 that is slightly smaller than the surface of the main body 22 is attached to the carry bag 20. By doing so, the lid 21 can be opened and closed. In the embodiment shown in FIG. 3, the carry bag 23 shows an example in which a lid 21 having the same size as the surface is attached to one surface of the main body 22.

  The fastener mounting structure will be described with reference to a cross-sectional perspective view shown in the lower right of FIG. The fastener tape 6 on one side of the pair of fastener tapes 6, 7 holding the fastener element 8 is attached to the edge of the lid 21, and the fastener tape 7 on the other side is attached to the edge of the main body 22. . At the edge of the lid body 21, the front fabric (exterior material) 9, the back fabric (interior material) 10 and the edge of the fastener tape 6 of the lid body 21 are covered with the strip-shaped piece 3 of the edging member 1. The stitches are sewn together at the sewing portion 5. In this embodiment, the rim material 11 is also stitched together, and the seam is covered with the head 12 of the rim material 11 so that the appearance is pleasingly arranged. A shape-retaining core member 4 is inserted into the head portion 2 of the edging member 1. Then, at the edge of the main body 22, the front fabric (exterior material) 9 and the back fabric (interior material) 10 of the main body 22 and the edge of the fastener tape 7 are covered with the edge tape 14, and are sewn together at the sewing portion 5. ing. Then, as described above, the position is adjusted so that the element 8 does not approach the main body side beyond the head 2 of the edging member 1, and the edging member 1 is disposed immediately below the element 8.

  The fastener mounting structure shown in the cross-sectional perspective explanatory view shown in the lower right part of FIG. 3 is the same as that shown in FIG. At the edge of the main body 22, the fastener tape 7 is sandwiched between the front fabric (exterior material) 9 and the back fabric (interior material) 10 of the main body 22, and the seam is sewn together at the sewing portion 5. There is no particular limitation on the method of stitching together at the edge, and it is only necessary that the fastener tape 7 is firmly fixed. Further, similarly to FIG. 2, the element 8 passes over the head 2 of the edging member 1 and moves toward the main body. The position should just be adjusted so that it may not approach. Also in this example, when sewing the element 7 at the edge of the main body 22, a ball edge material or an edging tape can be used in combination.

  FIG. 4 illustrates an operation mechanism for preventing the element from being pry open in the scissors according to the present invention, which will be described below in comparison with a function mechanism in which the element is pry open in the conventional scissors of FIG. In the conventional fastener mounting structure shown in FIG. 5, the fastener tape 6 is covered with the edge tape 11 and stitched together at the end of the lid 21 of the collar. Then, the fastener tape 7 is covered with the rim tape 14 at the end portion of the main body 22 of the heel and stitched together. Further, a core material 15 such as a steel wire is usually inserted in the head of the ball edge material 11. As shown in (5a), when a force is applied by pressing a pointed tool 30 against the center of the element 8 held by the fastener tapes 6 and 7, as shown in (5b), the bag body 22 is shown. The fastener tapes 6 and 7 are supported by the head of the ball edge material 11 in which the core material 15 is inserted, and only the element 8 is pushed down, and a force that opens left and right with respect to the element 8 is generated. Then, the pointed tip of the tool 30 becomes a point for opening the element 8, and the element is pruned into the elements 8 ′ and 8 ″ as shown in (5c).

The position is adjusted so as not to get over the head 2 and approach the main body. In (4a), when a force is applied by pressing the pointed tool 30 against the element 8, the shape-maintaining core material 4 is made of a rigid material, so that the element 8 is supported without being deformed. There is no point that triggers the opening of the element, and the force to open the element to the left and right does not work, preventing the element from being opened. Further, when a core material such as a steel wire is not inserted into the head 12 of the rim material 11, the head 12 of the rim material 11 is pushed downward as shown in (4b). Even in this case, the head 2 of the edging member 1 on which the shape-maintaining core material 4 is inserted is not deformed, and the element 8 is inclined with the fulcrum serving as a fulcrum, and the tool 30 slides on the element 8 and opens. I can't make a trigger point, and I can't open the element. Further, when a core material such as a steel wire is inserted into the head portion 12 of the ball edge member 11, as shown in (4c), the head portion of the edging member 1 in which the shape maintaining core material 4 is inserted and equipped. 2 and the head 12 of the ball edge member 11 support the element 8, and even if the tool 30 is pressed, the element 8 cannot be disengaged in the same manner.

  As described above, the edging member for covering the seam allowance part in which the fastener tape and the fabric constituting the main body or the lid body are sewn together has been shown as an example of being attached to the edge of the lid body. It can be easily understood that the same effect can be obtained even if the member is attached to the edge of the main body.

  As the fastener used in the bag of the present invention, a commonly used fastener in which an element made of a usual metal material or plastic material is attached to a fabric fastener tape can be used, and there is no particular limitation.
