  Hereinafter, non-limiting embodiments and features according to the present disclosure will be described with reference to FIGS. 1 to 19. Those skilled in the art can combine each embodiment and / or each feature without excessive explanation, and can also understand the synergistic effect of this combination. The overlapping description between the embodiments is basically omitted. The reference drawings are mainly for the purpose of describing the invention, and may be simplified for convenience of drawing. Each feature is understood as a separate individual feature that does not require a combination with other features, or as a combination with one or more other individual features. Describing all combinations of individual features is redundant for those skilled in the art and is omitted. The individual features are understood, for example, as universal features that are not only valid for the clips disclosed in the drawings, but also apply to various other clips.

  FIG. 1 is a schematic diagram showing a non-limiting example of use of the clip 1. As shown in FIG. 1, the clip 1 of the present disclosure can be used to detachably attach a chest strap 2 to a shoulder strap 3, but the application of the clip 1 should not be limited to this. In another example, the clip 1 is connected to a male or female member of the buckle, which facilitates a simple (removable) attachment of the buckle to the band and / or strap. A form in which another part, for example, a hook part (a so-called ring) is used instead of the buckle is also envisioned. A form in which at least two clips are connected to form a chest strap that does not require a strap is also assumed. The clip 1 can also be used to bind a band, a string, or paper.

  In yet another example, the clip 1 is connected to an item such as a plastic whistle. This item can be (removably) attached to the backpack strap via its clip portion. Clip 1 is configured to facilitate easier removal of clip 1 from the strap. Accordingly, it is facilitated to remove the item from the strap in a shorter time in an emergency and to sound the horn more quickly.

  In yet another example, clip 1 is used to hang a desired item on a band and / or string, such as a trouser belt. An example of a desired item includes, but is not limited to, a smartphone or a bag containing a wallet. The items hung on the band and / or the string are not limited to lightweight ones, but may be heavy ones. The clip 1 is configured to promote a simpler attachment and / or removal of the clip 1 while suppressing a decrease in the holding performance (which may be referred to as a gripping ability or a holding ability) of the clip 1. Therefore, a form in which the clip 1 is used for the purpose of suspending an item (for example, a tool) having a certain weight on the belt is also assumed. Again, the use or use of the clip 1 described above is merely a non-limiting example, and does not limit the use or use of the clip 1 at all.

  FIG. 2 is a schematic perspective view of the clip 1. FIG. 3 is a schematic side view of the clip 1. FIG. 4 is a schematic top view of the clip 1. FIG. 5 is a schematic cross-sectional view of the clip 1 and shows a cross-section taken along a dashed-dotted line X5-X5 in FIG. FIG. 6 is a bottom view of the clip 1. FIG. 7 is a rear side view of the clip 1. FIG. 8 is a front side view of the clip 1. FIG. 9 is a schematic side view showing a state before the clip 1 is operated. FIG. 10 is a schematic side view of the clip 1, showing a state where the second extending portion is bent and the opening height of the insertion opening of the clip 1 is increased. FIG. 11 is a schematic view showing a process of attaching the clip 1 to the shoulder strap 3.

  The double arrow LR in FIG. 2 indicates the left-right direction, the double arrow FB indicates the front-back direction, and the double arrow UD indicates the up-down direction. As will be understood from the description below, the left-right direction corresponds to the extending direction of the band or the string material sandwiched between the first extending portion 10 and the second extending portion 20. The front-back direction corresponds to the extending direction of the first and second extending portions 10 and 20 extending toward or away from the coupling portion 30. The up-down direction is a direction orthogonal to the left-right direction and the front-back direction described here. The left-right, front-back, and up-down directions can be redefined in light of the following description of clip 1. Assuming that the clip 1 shown in FIG. 1 is attached, the left-right direction corresponds to the extending direction of the shoulder strap 3. The front-back direction corresponds to the direction in which the chest strap 2 extends. The vertical direction corresponds to a direction orthogonal to the extending direction of the shoulder strap 3 and the extending direction of the chest strap 2.

  The clip 1 has first and second extending portions 10 and 20 and a coupling portion 30 in which respective base ends of the first and second extending portions 10 and 20 are coupled. The first and second extension portions 10 and 20 extend so as to be separated from the coupling portion 30 (that is, backward), and a holding space (40) is formed therebetween. The distal end of the first extending portion 10 faces the second extending portion 20 (particularly, the intermediate portion 25), and an insertion port 41 into the holding space 40 is defined. In the holding space 40 between the first and second extending portions 10 and 20, a band material or a string material can be inserted and held through an insertion port 41. When the band or the string is held between the first and second extending portions 10 and 20, the band or the string is left and right in the holding space 40 between the first and second extending portions 10 and 20. It can be displaced in the direction, but is not necessarily limited to this. Note that the first extension portion 10 may be called an upper extension portion, and the second extension portion 20 may be called a lower extension portion.

  The first extending portion 10 has a proximal end 11 coupled to the coupling portion 30 and a distal end 12 opposite to the proximal end 11 (in the front-rear direction). The base end 11 of the first extension 10 may be called a front end, and the front end 12 may be called a rear end. The second extending portion 20 has a proximal end 21 coupled to the coupling portion 30 and an opposite end 22 opposite to the proximal end 21 in the front-rear direction. The base end 21 of the second extending portion 20 may be called a front end, and the opposite end 22 may be called a rear end.

  The second extending portion 20 has an intermediate portion 25 extending between the base end 21 and the opposite end 22. The opposite end 22 is provided with an insertion opening 27 for the chest strap 2, but is not limited to this. As described above, a mode in which the opposite end 22 is integrally connected to another part (for example, a male or female member of a buckle or another clip) by injection molding is also envisioned. The distal end portion 12 of the first extending portion 10 faces the second extending portion 20 (in the end, an intermediate portion 25 thereof) and enters the holding space 40 between the first and second extending portions 10, 20. Is defined. As an option, a projection 70 protruding toward the second extending portion 20 (or, more specifically, the intermediate portion 25) is provided on the distal end portion 12 of the first extending portion 10. The insertion opening 41 of the clip 1 is partially closed by the projection 70. Typically, the clip 1 is a plastic part and can be manufactured by injection molding of a molten resin.

  The first extension 10 can have, but is not necessarily limited to, one or more openings 19 formed between the proximal end 11 and the distal end 12. In some cases, the first extension 10 is a frame-like portion surrounding one opening 19. When the first extending portion 10 is a frame-like portion, the band or the string material sandwiched between the first extending portion 10 and the second extending portion 20 can be visually recognized. Further, a constricted portion 50 or an opening 60 of the second extending portion 20 described later can be visually recognized through the opening 60 of the first extending portion. In some cases, the left-right width W10 of the first extension portion 10 decreases toward the coupling portion 30, thereby facilitating the insertion of the clip 1, for example, into the gap between the shoulder harness 4 and the shoulder strap 3. Facilitates insertion.

  The second extending portion 20 has an intermediate portion 25 where the constricted portion 50 is formed (see FIG. 6). The constricted portion 50 is formed in the second extending portion 20 (in the end, an intermediate portion 25) at a position between the insertion opening 41 of the clip 1 and the coupling portion 30, and accordingly, the second extending portion 20 is formed. Are easily bent. When the second extension 20 bends, the second extension 20 may assume an arcuate shape. More specifically, the second extending portion 20 can have a shape in which the constricted portion 50 is warped toward the first extending portion 10. The second extension 20 may be relatively rigid, and thus its arcuate shape may have a very shallow depth.

  As an option, when the width of the second extending portion 20 (in short, the intermediate portion 25) near the coupling portion 30 is W1 and the minimum width of the constricted portion 50 is W2, (W2 / W1) ≦ 0. .8 is satisfied. Thereby, the ease of deformation of the second extending portion 20 is promoted. In addition, the width of the second extending portion 20 (in the end, the intermediate portion 25) in the vicinity of the connecting portion 30 is the maximum width in the portion closer to the connecting portion 30 than the minimum width of the constricted portion 50. It can be read as the maximum width of the first taper portion 51 described later.

  The second extending portion 20, or the intermediate portion 25 at the end thereof, may include a portion extending with a constant thickness from the coupling portion 30 toward the insertion opening 41. Thereby, the ease of deformation of the second extending portion 20 is promoted. In some cases, the entire middle section 25 is flat. One or more concave portions 26 are provided on the lower surface 24 of the second extending portion 20 (in short, an intermediate portion 25 thereof), so that the deformability of the second extending portion 20 can be further promoted. Since the concave portion 26 is not provided on the inner surface 23 of the second extending portion 20, the flatness of the inner surface 23 of the second extending portion 20 is also secured at the same time. Note that the intermediate portion 25 of the second extending portion 20 may include one or more frame portions that define the concave portion 26. Further, by forming the thickness of the second extending portion 20 to be smaller than the thickness of the first extending portion 10, it is possible to further promote the ease of deformation.

  Specific modes of the constricted portion 50 are various. In some cases, the constricted portion 50 is configured symmetrically with respect to an axis AX that is parallel to the insertion direction (front-back direction) into the holding space 40 through the insertion port 41. Additionally or alternatively, the constriction 50 is shaped by the first and second tapered portions 51, 52 of the second extension 20. Specifically, the second extending portion 20 includes first and second tapered portions 51 and 52 connected to form the constricted portion 50. The first taper portion 51 becomes narrower as it moves away from the coupling portion 30 (rearward), and the second taper portion 52 becomes wider as it moves away from the first taper portion 51 (rearward). The distance between the left and right inclined edges 51m and 51n of the first tapered portion 51 decreases as the distance from the coupling portion 30 (rearward) increases. The distance between the left and right inclined edges 52m and 52n of the second taper portion 52 increases as the distance from the first taper portion 51 (rearward) increases. It can be said that the left and right inclined edges 51m and 51n of the first tapered portion 51 are tapered, and the left and right inclined edges 52m and 52n of the second tapered portion 52 are inversely tapered. In addition, the protrusion 70 of the distal end portion 12 of the first extension portion 10 protrudes toward a portion near the wide end of the second tapered portion 52. The first taper portion 51 may be called a front taper portion, and the second taper portion 52 may be called a rear taper portion.

  A left concave portion 54m is formed by the left inclined edge 51m of the first tapered portion 51 and the left inclined edge 52m of the second tapered portion 52. A right concave portion 54n is formed by the right inclined edge 51n of the first tapered portion 51 and the right inclined edge 52n of the second tapered portion 52. A minimum width portion 53 of the constricted portion 50 is defined between the bottom of the left recess 54m and the bottom of the right recess 54n. Note that a form in which the bottoms of the left and right recesses 54m and 54n are offset from each other in the front-rear direction without being arranged on the same axis parallel to the left-right direction is also assumed. Even in such a case, the minimum width portion 53 of the constricted portion 50 is defined between the bottom of the left recess 54m and the bottom of the right recess 54n. A form in which a bar-shaped portion having a constant left and right width is provided between the first taper portion 51 and the second taper portion 52 is also conceivable.

  In some cases, the clip 1 is configured to be easily inserted into the gap with the coupling portion 30 as an insertion end. In the example of FIG. 1, the clip 1 is configured to be easily inserted into a gap between the shoulder harness 4 and the shoulder strap 3. In another example, the clip 1 is easily inserted into another gap. Note that the following description may be made on the assumption that the clip 1 is inserted into the gap between the shoulder harness 4 and the shoulder strap 3, but this is not intended to limit the invention.

The first and second extending portions 10 and 20 extend so that the distance between the first and second extending portions 10 and 20 (the vertical distance) gradually increases as the distance from the coupling portion 30 increases. Additionally or alternatively, the inner surface 17 of the first extension 10 is provided at an angle with respect to the inner surface 23 of the second extension 20. When either or both of these conditions are satisfied, the ease of insertion of the clip 1 is promoted. In addition, when the protrusion 70 is provided on the distal end portion 12 of the first extending portion 10, a decrease in the holding performance of the clip 1 (for example, the ability to keep holding the shoulder strap 3) is suppressed by the protrusion 70. The protrusion 70 protrudes toward the middle part 25 of the second extension part 20. In some cases, the protrusion height H70 of the protrusion 70 is larger than the minimum thickness TH _min 1 of the distal end portion 12 of the first extension portion 10. This feature means that both the ease of insertion of the clip 1 and the holding performance of the clip 1 are compatible. Note that the protrusion height H70 of the protrusion 70 is larger than the minimum distance between the protrusion 70 and the second extending portion 20.

  Note that the inner surface 17 of the first extension 10 may be referred to as the lower surface of the first extension 10. Similarly, the inner surface 23 of the second extension 20 can be referred to as the upper surface of the second extension 20. The inner surface 17 of the first extending portion 10 and the inner surface 23 of the second extending portion 20 are arranged at least partially facing each other. A holding space 40 is at least partially defined between the inner surface 17 of the first extension 10 and the inner surface 23 of the second extension 20.

  The first extension portion 10 of the clip 1 has an upper surface 16 that is inclined downward as it extends toward the coupling portion 30. Additionally or alternatively, the coupling portion 30 has an upper surface 31 that slopes down (toward the front end of the coupling portion 30) as the distance from the first extension 10 increases. Thanks to the downward slope of the upper surface 16 of the first extension 10 and / or the upper surface 31 of the coupling part 30, the clip 1 can smoothly enter the gap between the shoulder harness 4 and the shoulder strap 3. As an addition or alternative to the upper surface 16 of the first extension portion 10 and / or the upper surface 31 of the coupling portion 30, the lower surface 24 of the second extension portion 20 (the intermediate portion 25 or the constricted portion 50) of the clip 1 and the coupling portion 30 The lower surface 32 is flush. The clip 1 can smoothly slide toward the gap of the shoulder strap 3 on one surface of the shoulder harness 4. In the second extending portion 20, there is a step between the lower surface 24 of the intermediate portion 25 and the lower surface 22j of the opposite end portion 22, but there is no problem in smooth sliding of the clip 1.

  Optionally, coupling portion 30 has at least one guide projection 34 extending in a direction opposite to first and second extensions 10, 20. The guide protrusion 34 may have an upper surface 31 that slopes down toward the front end of the guide protrusion 34. The thickness of the guide projection 34 can be reduced toward the front. Thereby, smooth entry of the entire clip 1 is promoted. In some cases, the coupling portion 30 has a pair of left and right guide protrusions 34. The thickness in the front-rear direction of the connecting portion 30 is reduced by the space between the pair of left and right guide projections 34, and the connecting portion 30 is suppressed from being excessively hard.

  In some cases, the position P53 of the minimum width portion 53 of the constricted portion 50 is different from the leading end position (rear end position) P1 of the leading end portion 12 of the first extending portion 10 in the first and second extending portions 10. , 20 are positioned closer to the inner wall surface 33 of the connecting portion 30 that connects the inner surfaces 17 and 23 (see FIG. 3). Additionally or alternatively, the first interval between the position P53 of the minimum width portion 53 of the constricted portion 50 and the distal end position P1 of the distal end portion 12 of the first extending portion 10 is D1, and When the second distance between the position P53 and the position P33 of the inner wall surface 33 of the connecting portion 30 connecting the inner surfaces 17 and 23 of the first and second extending portions 10 and 20 is D2, 0.4 <(D2 /D1)<2.3 is satisfied. More preferably, 0.7 <(D2 / D1) <1.5 is satisfied. When either or both of the above conditions are satisfied, the ease of deformation of the second extending portion 20 is promoted.

  The distal end position P1 of the distal end portion 12 of the first extension portion 10 is such that when a plane perpendicular to the front-rear direction is advanced from the opposite end portion 22 of the second extension portion 20 toward the coupling portion 30, the plane is the first position. It may be the position that first intersects the tip 12 of the extension 10. The position P33 of the inner wall surface 33 of the connecting portion 30 is such that when a plane perpendicular to the front-rear direction is moved backward from the front position of the connecting portion 30 toward the opposite end 22 of the second extending portion 20, the plane is connected to the connecting portion. It may be the position that first intersects the inner wall surface 33 of the 30.

  In some cases, a projection 70 protruding toward the second extending portion 20 (endwise, an intermediate portion 25 thereof) is provided on the distal end portion 12 of the first extending portion 10. The position P53 of the minimum width portion 53 of the constricted portion 50 is different from the tip position (lower end position) P2 of the projection 70 of the connecting portion 30 connecting the inner surfaces 17 and 23 of the first and second extending portions 10 and 20. It can be positioned closer to the inner wall surface 33. In addition or as an alternative, the fifth interval between the position P53 of the minimum width portion 53 of the constricted portion 50 and the tip position P2 of the protrusion 70 is D5, and the position P53 of the minimum width portion 53 of the constricted portion 50 is the first and second. When the sixth interval between the positions P33 of the inner wall surface 33 of the connecting portion 30 connecting the inner surfaces 17 and 23 of the extending portions 10 and 20 is D6, 0.4 <(D6 / D5) <2.3 is satisfied. To be satisfied. More preferably, 0.7 <(D6 / D5) <1.5 is satisfied. When either or both of the above conditions are satisfied, the ease of deformation of the second extending portion 20 is promoted. The tip position (lower end position) P2 of the projection 70 is such that when a plane perpendicular to the front-rear direction is advanced from the opposite end 22 of the second extending part 20 toward the coupling part 30, the plane is It may be the position that first intersects the tip (lower end).

  Referring to FIG. 9, an axis L <b> 2 connecting the tip position P <b> 1 of the tip portion 12 of the first extension portion 10 and the position P <b> 53 of the minimum width portion 53 of the constricted portion 50 to a plane L <b> 1 where the second extension portion 20 exists. Is an arbitrary angle in the range of 23 ° to 45 °, but should not be limited to this. By appropriately positioning the minimum width portion 53 of the constricted portion 50, the ease of deformation of the second extending portion 20 is promoted.

  As can be seen from a comparison between FIGS. 9 and 10, when the clip 1 is operated so as to increase the opening height H <b> 41 of the insertion port 41, the second extending portion 20 bends more than the first extending portion 10. More specifically, when the clip 1 is operated so that the distal end portion 12 of the first extension portion 10 is separated from the second extension portion 20 (particularly, the intermediate portion 25), the first extension portion 10 The amount of bending is smaller than the amount of bending of the intermediate portion 25 of the second extending portion 20. For example, with the clip 1 attached to the shoulder strap 3, the tip 12 of the first extension portion 10 is pushed away from the shoulder harness 4 with the thumb of one hand. Since the second extending portion 20 is a cantilever extending from the joining portion 30, the second extending portion 20 starts to bend starting from the joining portion 30. Since the constricted portion 50 is formed in the intermediate portion 25 of the second extending portion 20, the portion closer to the coupling portion 30 than the constricted portion 50 (that is, the first tapered portion 51) is more connected than the constricted portion 50. The portion far from 30 (that is, the second tapered portion 52) is largely displaced. Therefore, the minimum width portion 53 of the constricted portion 50 warps toward the first extending portion 10. The opening height H41 of the insertion opening 41 of the clip 1 increases, and the clip 1 can be removed from the shoulder strap 3. When attaching the clip 1 to the shoulder strap 3, the projection 70 is pressed by the shoulder strap 3, and the first extension 10 is pushed away from the shoulder harness 4, and the second extension 10 is pressed in the same manner as described above. The part 20 bends.

  FIG. 11 is a schematic view showing a process of attaching the clip 1 to the shoulder strap 3. For convenience of illustration, the illustration of the shoulder harness 4 is omitted. First, as shown in FIGS. 11A and 11B, the clip 1 is inserted into a gap between the shoulder harness 4 and the shoulder strap 3. It may be advantageous to employ one or more of the features described above to enhance the ease of insertion of the clip 1. Next, as shown in FIGS. 11C and 11D, the clip 1 having passed through the gap between the shoulder harness 4 and the shoulder strap 3 is moved in the opposite direction, and the clip 1 is held through the insertion opening 41 of the clip 1. The shoulder strap 3 is inserted into the space 40. At this time, as described above, the distal end portion 12 of the first extension portion 10 is pushed away from the shoulder harness 4 by the shoulder strap 3, and the second extension portion 20 bends accordingly.

  As shown in FIGS. 12 to 19, as an alternative to the above-described constricted portion 50, an opening 60 may be provided in the intermediate portion 25 of the second extending portion 20. The features of the clip 1 described above also apply to the form in which the opening 60 is provided in the intermediate portion 25 of the second extending portion 20, and a repeated description will be omitted.

  As shown in FIGS. 15 and 19, the width of the second extending portion 20 (in the end, an intermediate portion 25) near the coupling portion 30 is W3, and the total width of a plurality of portions separated by the opening 60 is shown. Is W4, W4 / W3 ≦ 0.8 is satisfied. In the case shown in FIGS. 15 and 19, the total width W4 = W4a + W4b. Thereby, the ease of deformation of the second extending portion 20 is promoted. Optionally, the intermediate portion 25 includes a portion extending at a constant thickness from the coupling portion 30 toward the insertion opening 41 and / or one or more concave portions 26 on the lower surface 24 of the second extending portion 20 (intermediate portion 25). Is provided. The recess 26 can be formed on the outer periphery of the opening 60.

  Similar to D1, D2, D5, and D6 described for the constricted portion 50, a similar relationship can be established for the opening 60 formed in the second extending portion 20 (in short, the intermediate portion 25). Specifically, the third interval between the center position P60 of the opening 60 and the tip position P1 of the tip portion 12 of the first extension portion 10 is D3, and the center position P60 of the opening 60 and the first and second extensions When the fourth distance between the positions P33 of the inner wall surfaces 33 of the connecting portions 30 connecting the inner surfaces of the portions 10 and 20 is D4, 0.4 <(D4 / D3) <2.3 is satisfied. More preferably, 0.7 <(D4 / D3) <1.5 is satisfied. Additionally or alternatively, the seventh distance between the center position P60 of the opening 60 and the tip position P2 of the protrusion 70 is D7, and the center position P60 of the opening 60 is connected to the inner surfaces of the first and second extending portions 10 and 20. Assuming that an eighth interval between the positions P33 of the inner wall surfaces 33 of the connecting portion 30 is D8, 0.4 <(D8 / D7) <2.3 is satisfied. More preferably, 0.7 <(D8 / D7) <1.5 is satisfied.

  The specific mode of the opening 60 is various. In some cases, similarly to the constricted portion 50, the opening 60 is configured symmetrically with respect to an axis AX that is parallel to the insertion direction (front-back direction) into the holding space 40 through the insertion opening 41. In some cases including the configuration of FIG. 15, in order to achieve both easy insertion of the clip 1 and easy deformation of the second extending portion 20, the intermediate portion 25 of the second extending portion 20 in the direction away from the coupling portion 30. Right and left and right and left of the opening 60 increase synchronously. In short, the width increases as the intermediate portion 25 of the second extending portion 20 moves away from the coupling portion 30, and the width increases as the opening 60 moves away from the coupling portion 30. The right edge 28 of the second extension 20 and the right edge 61 of the opening 60 are parallel, and the left edge 29 of the second extension 20 and the left edge 62 of the opening 60 are parallel. As shown in FIG. 19, it is assumed that the second extending portion 20 extends in the front-rear direction with a constant left-right width, and the opening 60 also extends in the front-rear direction with a constant left-right width.

  In view of the above teachings, those skilled in the art can make various changes to each embodiment. Reference numerals in the claims are for reference only and should not be referred to for the purpose of limiting the claims.
