German Utility Model No. 2015103624

In the above-mentioned fastener, in the state of use shown in FIG. 9A, when a large external force is applied in the direction away from the back of the backpack via the band, the hook portion buckles or the upper and lower end mounting portions are sewn. Was in danger of being damaged. As a countermeasure, if the overall wall thickness is increased in order to increase the rigidity, the band detachability will deteriorate and the design will be impaired.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to maintain a simple shape of a substantially flake shape, and to move away from the attached surface of the mating article in a used state in which the article is hooked. It is an object of the present invention to provide a fastener and a mounting structure thereof, which are not easily damaged by a large external force and can improve the design. Other purposes will be clarified in the following description.

In order to achieve the above object, the invention of claim 1 is a fastener having a mounting portion for locking to a counterpart article and a hook portion for hanging or hooking small items via a band or a string. It forms a substantially piece shape that is long in the vertical direction, has a rigid body portion that is extended in the longitudinal direction of the fragment shape and is thicker than the mounting portion, and has the mounting portion and the mounting portion on the left and right sides of the rigid body portion. Each of the different hook portions is formed, and when the hook portion receives an external force in the direction away from the mating article in a mounted state in which the mounting portion is locked to the mating article in the longitudinal direction, the whole is formed. Is characterized in that it can absorb an external force by rotating or swinging in the width direction with the locked portion of the mounting portion as a fulcrum.

It is more preferable that the above invention is embodied as in claims 2 to 7. That is,
(A) The rigid body portion is longer than the mounting portion and the hook portion, and the mounting portion is thinner than the rigid body portion and the hook portion (claim 2).
(A) The hook portion has a configuration in which a hooking groove is partitioned between the hook portion and the rigid body portion (claim 3).

(C) The fastener mounting structure according to any one of claims 1 to 3, wherein the fastener is positioned on the mounted portion of the skin material that partitions the outer surface portion of the mating article. The mounting portion is linearly locked to the mounted portion along the longitudinal direction of the piece (claim 4).
(D) The attachment portion of the skin material is configured to sandwich the attachment portion between the first skin portion and the second skin portion arranged in a polymerized state with respect to the first skin portion (d) . Claim 5).

(E) In claim 5, the second skin portion has a folded portion that is bent inward, and the mounting portion is sandwiched between the first skin portion and the folded portion (claim). Item 6).
(F) In claims 4 to 6, the skin material is made of a cloth-based material (including woven fabric, knitting, lace, felt, non-woven fabric, etc.), and the attached portion is locked to the attached portion by sewing. (Claim 7).

The invention of claim 1 is excellent in the following points as a fastener in the form of a substantially piece.
First, in the present invention, as compared with the configuration in which the mounting portion is a piece-shaped upper and lower end portion as in Patent Document 1, the hook portion is separated from the mating article in the mounted state in which the mounting portion is locked to the mating article. When it receives an external force, it can rotate or swing around the portion locked in the longitudinal direction of the mounting portion as a fulcrum to absorb the external force, thereby alleviating or eliminating the risk of damage. In addition, the length of the piece can be shortened as compared with the configuration of the upper and lower ends because the mounting portion extends in the longitudinal direction of the piece, and the degree of freedom in design can be expanded.
Secondly, in the fastener of Patent Document 1, since the mounting portion is a piece-shaped upper and lower end portion, dust or the like accumulates in the gap formed between the intermediate portion between the upper and lower end portions and the article on the other side, for example. When it was crowded on the train, there was a risk that someone else's string, button, etc. would be inadvertently caught in the gap. On the other hand, in the present invention, since the mounting portion is locked to the mating article along the longitudinal direction of the flank, such a defect can be eliminated and the cleanliness and safety can be improved.

In the invention of claim 2, as inferred from each (a) of FIGS. 1 and 5, the first skin portion is formed by a rigid body portion that is long in the longitudinal direction and thicker than the attachment portion in a state where the fastener is attached to the mating article. It is expected to have a function that makes it difficult to see between the second epidermis and the second skin, and demonstrates the appearance and novelty of the design. Further, since the mounting portion is formed thinner than the rigid body portion and the hook portion, it is easy to mount by sewing as shown in FIGS. 4 and 5, and the mounting portion is the attached portion (first skin portion) of the skin material. (2) Even if it is sandwiched between the epidermis, it functions so that it does not become too thick and spoil the appearance.

In the invention of claim 3, since the hook portion forms a hooking groove between the hook portion and the rigid body portion, high strength can be imparted and a sense of stability can be imparted.

In the invention of claim 4, since the attachment portion is linearly locked to the attachment portion of the skin material that partitions the outer surface of the mating article along the longitudinal direction of the piece by sewing or the like, Patent Document 1 It is superior in mounting operability as compared with the configuration in which the upper side and the lower side of the piece are sewn.

In the invention of claim 5, as shown in FIG. 1A, the mounting portion is sandwiched between the first skin portion and the second skin portion and is locked by sewing or the like, so that one side of the fastener is locked. About half of it disappears and a novel design can be obtained.

In the invention of claim 6, since the second skin portion has a folded portion bent inward and the mounting portion is sandwiched between the first skin portion and the folded portion, sewing is performed as shown in FIG. 4 (a). The mounting line such as is also invisible, and the design can be further improved.

In the invention of claim 7, the skin material is made of a flexible cloth-based material, and the mounting portion can be efficiently locked to the mounted portion by straight stitching. When the fastener is attached, it has a novel appearance, which makes it suitable for personal items such as backpacks and shoulder bags.

Hereinafter, the optimum embodiment of the present invention will be described with reference to the drawings. In this description, the fastener structure, the attachment structure to the mating article, the usage example, and the modification will be described in detail in this order.

(Fastener structure) As shown in the drawing, the fastener 10 of the morphological example is made of a resin injection-molded body having a substantially fragmented shape as a whole. Further, the fastener 10 includes a rigid body portion 12 extending in the longitudinal direction, a mounting portion 11 integrated on the left side or the right side of the rigid body portion 12, and a hook portion 13 integrated on the right side or the left side of the rigid body portion 12. And form. In other words, the fastener 10 is divided into the left side and the right side of the rigid body portion 12 in which the mounting portion 11 and the hook portion 13 extend in the longitudinal direction, and the upper end surface 14a and the lower end surface 14b are safety and From the point of view of appearance, both have a rounded arc shape.

Here, the mounting portion 11 has a thin flat plate shape joined to the rigid body portion 12 with a step 16. The step 16 is located substantially in the middle of the plate width and extends linearly from the upper end surface 14a to the lower end surface 14b in the longitudinal direction. Further, the plate thickness setting of the mounting portion 11 is such that the fastener 10 is mounted on a mating article such as a backpack, and is easily mounted by sewing without giving a feeling of foreign matter. On the other hand, the rigid body portion 12 is provided with a long groove 15 in the vertical direction downward from the upper side surface to partition the hook portion 13 for hooking.

Further, the hook portion 13 has a shape that allows the band 6 and strings to be easily hooked, and extends straight upward from the base portion 13a, which is a portion close to the lower end surface 14b connected to the rigid body portion 12, and the base portion 13a. It has an arm portion 13b and a small protrusion 13c protruding inside the tip of the arm portion 13b.

The long groove 15 has a widest groove width so that the inlet 15a can easily insert a band or a string, and the portion following the inlet 15a is a non-straight meandering groove 15b so that the band or the like cannot be easily pulled out. The lower side following the meandering groove 15b is formed in the vertical groove 15c so that a band, a string, or the like can be stably inserted. Of these, the meandering portion 15b is non-linear due to the presence of the small protrusion 13c at the inner tip of the arm portion and the small protrusion 12a provided on the end surface of the rigid body portion 12 and protruding slightly below the small protrusion 13c. It has become.

The wall thickness T1 of the mounting portion 11 is smaller than the wall thickness T2 of the rigid body portion 12 and the wall thickness T3 of the hook portion 13 (see FIG. 2C). The wall thickness T1 is as thin as possible so as to secure the strength of the sewn portion with respect to the first skin portion 2 and the second skin portion 3, which will be described later, and the hook portion 13 or the whole is elastic enough to rotate around the sewing line 4 as a fulcrum. Is set to provide. By making the mounting portion 11 thin, the unevenness of the portion to which the fastener 10 is mounted is reduced to improve the appearance and reduce the weight.

On the other hand, the wall thickness T2 of the rigid body portion 12 is a thick portion larger than the wall thickness T1 of the mounting portion 11, and when an article such as a helmet is locked to the hook portion 13, it can withstand the load and does not buckle. It has rigidity. The upper and lower end portions of the rigid body portion 12 substantially partition the upper end surface 14a and the lower end surface 14b of the fastener 10. Further, the length of the fastener 10 is usually set to 10 cm or less, but it may be longer than 10 cm.

(Mounting structure) The above fasteners 10 are attached to the left and right sides of the backpack, which is the other party's article, as in Patent Document 1, for example. 1 (a) shows a state in which two fasteners 10 are symmetrically attached to an attached portion 2 of a mating article such as a backpack 1, and FIGS. 4 to 6 show an attached portion to which the fastener 10 is attached. The relationship between the first skin portion 2 which is the attached portion, the second skin portion 3 overlapped with the first skin portion 2, and the fastener 10 among the skin materials partitioning the 7 is shown.

That is, the above fastener 10 is positioned with the mounting portion 11 sandwiched between the first skin portion 2 and the second skin portion 3, and is positioned with respect to each of the skin portions 2 and 3, for example, from the skin portion 3 side. It is locked in a straight line by sewing along the longitudinal direction of the taking portion 11. Further, in this configuration, as inferred from the drawing, the second skin portion 3 has a folded portion 3a bent inward, and the mounting portion 11 is sandwiched between the first skin portion 2 and the folded portion 3a. It is sewn in a state of being sewn.

In such a mounting structure, when the back pad 1 which is the other party's article to which the fastener 10 is attached is only viewed from the outside, not only the mounting portion 11, but also the sewing line 4 and the seam 4a are not visible at all, so that the appearance looks good. It will be good. Specifically, since the rigid body portion 12 is longer in the longitudinal direction and thicker than the mounting portion 3 with the fastener 10 attached to the mating article, the space between the first skin portion 2 and the second skin portion 3 is reached. It is hard to see and gives a novel appearance and design.

Further, in this structure, since the mounting portion 11 is formed thinner than the rigid body portion 12 and the hook portion 13, it is easy to mount by sewing as shown in FIGS. 4 and 5, and the mounting portion 11 is mounted on the skin material. Even if it is sandwiched between the (first skin portion) 2 and the second skin portion 3, there is no possibility that the appearance will be spoiled due to the excessive thickness.

(Usage example) FIG. 1A shows a use in which a helmet (not shown) hooks a band 8 on the helmet side to a hook portion 13 with respect to two fasteners 10 attached to a backpack 1 which is an article on the other side. The state is schematically shown. In this hooking operation, the pair of bands 8 are inserted into the long groove 15 of the fastener 10 on the corresponding side so as to be hooked to the hook portion 13. It is preferable that each band 8 is pulled out from the back surface side to the front surface side of the fastener 10 with respect to the long groove 15. Further, the small items to be hooked on the hook portion 13 are not limited to the helmet, and may be, for example, a band for putting ped bottles, writing tools, lunch boxes, various tools, etc., a storage bag with a string, or similar small items.

In the used state where a small item such as a helmet is hooked on the fastener 10 as described above, the hook portion 13 receives an external force in a direction of widening the width of the long groove 15 or a direction away from the article on the other side via the band 8 on the helmet side. In such a case, as illustrated in FIG. 6B, the entire body can be rotated or swung around the sewing line 4 locked in the longitudinal direction of the mounting portion 11 as a fulcrum to absorb the external force. Thereby, the fastener 10 can alleviate or eliminate the risk of breakage as compared with the configuration of Patent Document 1. Further, since the attachment portion 11 extends in the longitudinal direction of the fragment shape, the length of the piece shape can be shortened as compared with the configuration in which the upper and lower end portions are locked as in Document 1, and the degree of freedom in design can be expanded.

In addition, in this fastener 10, since the attachment portion 11 is locked to the attached portion 2 of the mating article by sewing or the like along the longitudinal direction of the piece, the attachment portion is one piece like the fastener in Document 1. If it is the upper and lower ends of the shape, there is a risk that dust etc. will collect in the gap created between the middle part between the upper and lower ends and the article on the other side, or that another person's string or button will be inadvertently caught in the gap. Can be eliminated and cleanliness and safety can be improved. Further, as shown in FIG. 1A, the mounting portion 11 is locked by sewing or the like while being sandwiched between the first skin portion 2 and the second skin portion 3, so that the fastener 10 is engaged in the longitudinal direction. A novel design can be obtained by making almost half of the one side invisible.

(Modification 1) FIG. 7A is a perspective view showing a modification of the fastener 10 described above, and FIG. 7B schematically shows the mounting structure thereof. In this description, the same reference numerals are given to the parts that are the same as or similar to the above-mentioned embodiment, and duplicated descriptions are omitted as much as possible.

The fastener 10 has a plurality of mounting holes 11a provided in the mounting portion 11. Each mounting hole 11a is provided on a straight line, and has a hole diameter corresponding to caulking or hooking, that is, a shaft-shaped fixing member 9A as a mounting means. In this mounting structure, the fastener 10 holds the mounting portion 11 between the mounted portion (first skin portion) 7 set as the skin material of the mating article and the second skin portion 8. It is locked by the shaft-shaped fastener 9A. In this case, it is preferable to provide through holes in the skin portions 7 and 8. Such a configuration is a preferable example as a material of at least the attached portion (first skin portion) 7 of the skin material constituting the mating side article, for example, made of leather or a relatively hard material similar thereto.

(Modification 2) FIG. 8A is a perspective view showing a second modification of the fastener 10 described above, and FIG. 8B schematically shows the mounting structure thereof. Also in this explanation, the same reference numerals are given to the parts that are the same as or similar to the above-mentioned morphological examples, and the changed points are clarified.

The fastener 10 has an elongated hole 11b provided in the mounting portion 11. The elongated hole 11b has a straight groove shape, and the hole width is set to about 1/3 of the plate width of the mounting portion 11 in consideration of the rigidity of the mounting portion. In this mounting structure, the fastener 10 holds the mounting portion 11 between the mounted portion (first skin portion) 7 set as the skin material of the mating article and the second skin portion 8. Locked by a single or multiple staples 9B.

In the locked state, the corresponding portions of the skin portions 7 and 8 are slightly pushed into the elongated holes 11b so that the stapler 9B is inconspicuous. Such a configuration is also another example suitable when the material of the attached portion (first skin portion) 7 of the skin material constituting the mating article is similar to that of thick cloth or non-woven fabric.

As described above, the present invention may have the configuration specified in the claims, and the details can be variously changed as needed as in Modifications 1 and 2. Further, the use of the fastener is not limited to the backpack, and is suitable for, for example, a school bag, a shoulder bag, a Boston bag, or a bag similar to them as bags.
