Description

[Technical field]

[0001] The present invention relates to a strap for hanging a carry-on item. [Background technology]

[0002] Conventionally, there is known a strap for hanging carry-on items that has a string to be worn around the neck or shoulder, and that has a connector that is disposed between adjacent first and second string portions of the string to connect the first and second string portions and that disconnects the first and second string portions when an overload is applied, thereby separating the string into two portions (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-12073 A Summary of the Invention [Problem to be solved by the invention]

[0004] With this strap for hanging carry-on items, when the strap is hung around the neck or shoulder and gets caught on an external structure, a pulling force is applied to the strap, releasing the connection with the connector, causing the strap to break into two and come off from the neck or shoulder. By the way, there are straps for hanging carry-on items that have a structure in which the length of the hanging string can be adjusted by moving the feed can. In this case, even if the above-mentioned connector is provided, there is a risk that the loop formed by the part of the string that is doubled in the feed can may be accidentally hung around the neck or shoulder. In this case, the loop will expand to a certain extent, but the loop itself will not break, so the neck or shoulder will be pulled. The present invention has been made in consideration of the above circumstances, and aims to provide a strap for hanging carry-on items that can break a loop formed from a string portion doubled over by a feed can when an overload acts on the loop. [Means for solving the problem]

[0005] The first method is A strap for hanging a carry-on item is provided with a string for hanging around the neck or shoulder, and the string has a loop formed by doubling the length of the string by providing a feed ring for adjusting the length of the string, A first connector that connects adjacent cord portions of the hanging cord and releases the connection to break the hanging cord when an overload is applied; and a second connector that connects adjacent string portions in the loop and releases the connection to break the loop when an overload is applied. The strap for hanging carry-on items is characterized by the above.

[0006] The second means is the first means, characterized in that the second connector is provided between one end of a first string portion passed through the feed can and a second string portion having one end engaged with the feed can, and is movable relative to the second string portion as the feed can moves.

[0007] The third means is the first means, characterized in that the second connector is attached to a string portion having one end engaged with the feeder can, folded back at a point other than the feeder can, and passed through the feeder can.

[0008] The fourth measure is A strap for hanging a carry-on item is provided with a string for hanging around the neck or shoulder, and the string has a loop formed by doubling the length of the string by providing a feed ring for adjusting the length of the string, The two ends of the hanging strap are configured to be individually connected to carry-on items, a first connector that connects at least one end of the hanging cord to the carried item and that disconnects at least one end of the hanging cord from the carried item when an overload is applied; and and a second connector that connects adjacent string portions in the loop and releases the connection to break the loop when an overload is applied. The strap for hanging carry-on items is characterized by the above.

[0009] The fifth means is the first, third or fourth means, characterized in that the second connector is provided on a string portion located on the inside of the loop.

[0010] The sixth means is the fifth means, characterized in that the hanging strap is provided with a carrying item attachment for attaching carrying items. Effect of the Invention

[0011] According to the first to third means, if excessive pulling force is applied to the hanging cord when it is properly hung around the neck or shoulder, the first connector becomes overloaded, the connection between the cord portions is released, the hanging cord is severed, and the hanging cord comes off from the neck or shoulder. Furthermore, if excessive pulling force is applied to the loop when it is hung around the neck or shoulder, for example, after the loop expands, the second connector becomes overloaded, the connection between the string portions is released, the loop breaks, and finally the hanging string comes off from the neck or shoulder. In this case, in the first and third means, the hanging string is released from the neck or shoulders by, for example, two-stage separation of the loop and the hanging string, whereas in the second means, the hanging string is released from the neck or shoulders at the same time that the loop is separated.

[0012] According to the fourth means, when the strap is properly hung around the neck or shoulder, if an excessive pulling force is applied to the strap, the connection between the strap and the carried item is released, causing the strap to be separated from the carried item and the strap to come off from the neck or shoulder. Furthermore, if excessive pulling force is applied to the loop when it is hung around the neck or shoulder, for example, after the loop expands, the second connector becomes overloaded, the connection between the string portions is released, the loop breaks, and finally the hanging string comes off from the neck or shoulder.

[0013] According to the fifth means, the second connector is provided on the part of the string that is located on the inside of the loop created by the provision of a feed can, so that when the hanging string is properly attached, the second connector is difficult to see from the outside, making it possible to realize an attractive-looking strap for hanging carry-on items.

[0014] According to the sixth aspect, the carry-on item can be easily attached via the carry-on item attachment tool. [Brief description of the drawings]

[0016] The following describes a strap for hanging carry-on items according to an embodiment of the present invention.

[0017] [First embodiment] FIG. 1 is a perspective view showing a strap 100 for hanging a portable item according to the first embodiment. The strap 100 for hanging a carry-on item includes a hanging cord 10 that can be hung around the neck or shoulder. The hanging cord 10 has a first connector 20, a second connector 30, a feed ring 40, a D-ring 50, and a strap part 60 attached thereto. "10 Hanging Cords" The hanging string 10 is configured to include string portions 11, 12, and 13 which are flat strings. One end 11a of the string portion 11 is locked to the feed can 40, and the other end 11b is locked to the second connector 30. The locking structure of the feed can 40 and the locking structure of the second connector 30 will be described later. One end 12a of string portion 12 is secured to second connector 30, folded back at first connector 20 and passed through feed can 40, and the other end 12b is secured to D-can 50. The securing structure of second connector 30, the folded back structure of first connector 20, the passing structure of feed can 40, and the securing structure of D-can 50 will be described later. Furthermore, one end 13a of string portion 13 is locked to D-ring 50, and the other end 13b is locked to first connector 20. The locking structure of D-ring 50 and the locking structure of first connector 20 will be described later. The string portion between the feed can 40 and the first connector 20 is doubled to form a length-adjustable string portion.

[0018] 《1st connector 20》 FIG. 2 is a perspective view showing the male member 21 and the female member 22 of the first coupler 20, and FIG. 3 is a diagram showing the engagement relationship between the male member 21 and the female member 22 of the first coupler 20 and the string portion. The first connector 20 is made of plastic and is composed of a male device (connecting piece) 21 and a female device (connecting piece) 22. This first connector 20 is for connecting the folded-back portion of the string portion 12 and the other end 13b of the string portion 13, and releases the connection when an overload is applied.

[0019] <Male tool 21> A knob 21a is provided on the male component 21. An insertion piece 21b is formed to protrude from one side of the knob 21a. Furthermore, semi-spherical fitting protrusions 21c are formed on both sides of the insertion piece 21b. A string-passing hole 21d is formed on the other end side of the knob portion 21a. The string portion 12, one end portion 12a of which is engaged with the male device 31 (FIG. 4) of the second connector 30, is passed through the string-passing hole 21d from the back side and folded back toward the feed can 40. In other words, the string portion 12 passed through the string-passing hole 21d forms a folded back portion.

[0020] <Female Tool 22> The female device 22 is provided with a knob 22a. An insertion hole 22b into which the insertion piece 21b of the male device 21 is inserted is formed at one end of the knob 22a. The knob 22a also has a fitting hole 22c that fits onto the fitting protrusion 21c when the insertion piece 21b of the male device 21 is inserted into the insertion hole 22b. The wall constituting the knob portion 22a of the female device 22 has elasticity, and when the insertion piece 21b of the male device 21 is inserted into the insertion hole 22b, it is elastically deformed by the sliding contact of the fitting protrusion 21c, and when the fitting protrusion 21c reaches the fitting hole 22c, the elastic force causes the fitting protrusion 21c to fit into the fitting hole 22c. On the other hand, when a strong force acts to separate the male device 21 and the female device 22, the wall constituting the knob portion 22a is elastically deformed by the sliding contact of the fitting protrusion 21c, and the fitting protrusion 21c comes out of the fitting hole 22c, and the engagement between the fitting protrusion 21c and the fitting hole 22c is released.

[0021] A string hole 22d is formed on the other end side of the tab 22a. The other end 13b of the string portion 13, one end 13a of which is engaged with the D-ring 50, is passed through the string hole 22d from the front side, folded back, and immediately thereafter sewn to the back side of the string portion 13.

[0022] 《Second connector 30》 FIG. 4 is a perspective view showing the male member 31 and the female member 32 of the second connector 30, and FIG. 5 is a diagram showing the engagement relationship between the male member 31 and the female member 32 of the second connector 30 and the string portion. The second connector 30 is made of plastic and is composed of a male connector (connecting piece) 31 and a female connector (connecting piece) 32. This second connector 30 is for connecting the other end 11b of the string portion 11 and one end 12a of the string portion 12, and releases the connection when an overload is applied.

[0023] <Male tool 31> A knob 31a is provided on the male component 31. An insertion piece 31b is formed to protrude from one side of the knob 31a. Moreover, semi-spherical fitting protrusions 31c are formed on both sides of the insertion piece 31b.

[0024] On the other end side of the gripping portion 31a, a string through-hole 31d is formed. One end portion 12a of the string portion 12 is passed through the string through-hole 31d from the front side, folded back, and then sewn to the back side of the string portion 12 immediately after that.

[0025] 〈Female tool 32〉 The female tool 32 is provided with a gripping portion 32a. At one end of this gripping portion 32a, an insertion hole 32b into which the insertion piece 31b of the male tool 31 is inserted is formed. Also, in the gripping portion 32a, when the insertion piece 31b of the male tool 31 is inserted into the insertion hole 32b, a fitting hole 32c that fits into the fitting protrusion 31c is formed. The wall constituting the gripping portion 32a of this female tool 32 has elasticity. When the insertion piece 31b of the male tool 31 is inserted into the insertion hole 32b, it elastically deforms due to the sliding contact of the fitting protrusion 31c, and when the fitting protrusion 31c reaches the fitting hole 32c, the fitting protrusion 31c fits into the fitting hole 32c by the elastic force. On the other hand, when a strong force acts to separate the male tool 31 and the female tool 32, the wall constituting the gripping portion 32a elastically deforms due to the sliding contact of the fitting protrusion 31c, and the fitting protrusion 31c comes out of the fitting hole 32c, releasing the fitting between the fitting protrusion 31c and the fitting hole 32c.

[0026] On the other end side of the gripping portion 32a, a string through-hole 32d is formed. The other end portion 11b of the string portion 11 is passed through the string through-hole 32d from the front side, folded back, and then sewn to the back side of the string portion 11 immediately after that.

[0027] 《Feed can 40》 FIG. 6 is a perspective view showing the feed can 40, and FIG. 7 is a view showing the engagement relationship between the feed can 40 and the string portion. The feed can 40 is for adjusting the length of the hanging string 10 by changing the length of the string portion for adjusting the length of the hanging string 10. The feed can 40 is made of plastic and is formed in a shape like the Chinese character 'Ri' in plan view. Specifically, the feed can 40 is integrally molded with plastic, and in plan view, it is rectangular, and two string through-holes 41b and 41c are formed with the central horizontal bar 41a in between.

[0028] One end 11a of the string portion 11 is engaged with the horizontal bar 41a of the feed can 40. In other words, one end 11a of the string portion 11 is passed through the string hole 41b from the back side to the front side of the feed can 40, and then through the string hole 41c from the front side to the back side, and is folded back so as to enclose the horizontal bar 41a, and the folded back portion is sewn to the back side of the string portion 11 immediately after being folded back.

[0029] In addition, the string portion 12 folded back by the male device 21 of the first connector 20 is passed through the string hole 41b of the feed can 40 from the back side to the front side, and further, the string portion 12 is passed through the through hole 41c from the front side to the back side.

[0030] "D-ring 50" FIG. 8 is a diagram showing the engagement relationship between the D-ring 50 and the string portion. D-ring 50 is made of metal, although not limited thereto, and is provided for attaching strap part 60 (see FIG. 1). Other end 12b of string portion 12 and one end 13a of string portion 13 are engaged with D-ring 50. D-ring 50 has straight rod portion 50a and arc-shaped portion 50b. One end 13a of string portion 13 is passed through the space formed by straight rod portion 50a and arc-shaped portion 50b and is folded back so as to enclose straight rod portion 50a, and the folded back portion is sewn to the back side of string portion 13 immediately after folding. At that time, the other end 12b of string portion 12 is sandwiched between the folded back portion and string portion 13, and is simultaneously sewn to the back side of string portion 13.

[0031] "Strap parts 60" The strap part 60 is provided for hanging carry-on items.

[0032] 《How to use》 The strap 100 for hanging a portable item is used by hanging a portable item from the strap part 60 and hanging the hanging string 10 around the neck or shoulder in the correct way. Here, the correct way means treating the string part 12 that is folded back and doubled by the first connector 20, i.e., the length adjustment string part, as if it were a single string part, and hanging it around the neck or shoulder (Fig. 9).

[0033] Effects of the First Embodiment When the strap 100 for hanging a portable item is hung around the neck or shoulder in the correct way (FIG. 9), if the strap 100 for hanging a portable item gets caught on an external object or person for some reason, an excessive pulling force is applied to the hanging cord 10. In this case, a large force acts between the male part 21 and the female part 22 of the first connector 20, which separates them. As a result, the engagement between the male part 21 and the female part 22 of the first connector 20 is released, the hanging cord 10 is cut into two, and the hanging cord 10 comes off from the neck or shoulder.

[0034] Also, when the strap 100 for hanging a carry-on item is hung around the neck or shoulder in an irregular manner, that is, when the loop consisting of the doubled string portion 12 for length adjustment is hung around the neck or shoulder (FIG. 10), if the strap 100 for hanging a carry-on item is caught by an external object or person for some reason, an excessive pulling force is applied to the loop. In this case, the feed can 40 moves along the hanging string 10 and the loop expands. When it reaches its limit, a large force acts between the male member 31 and the female member 32 of the second connecting device 30 so as to separate them. As a result, the engagement between the male member 31 and the female member 32 of the second connecting device 30 is released, and the loop of the length adjustment string portion is broken. At this stage, the string portion 12 becomes single-layered, but the hanging string 10 does not come off the neck or shoulder yet. In this state, if excessive pulling force is applied to the hanging cord 10, the male member 21 and female member 22 of the first connector 20 will eventually disengage, the single-layered hanging cord 10 will be cut into two, and the hanging cord 10 will come off from the neck or shoulders. In this case, depending on the load, the release of the connection by the second connector 30 may be slower than the release of the connection by the first connector 20.

[0035] In this way, the hanging cord 10 breaks not only when it is hung around the neck or shoulder in a proper way, but also when it is hung around the neck or shoulder in an improper way. Therefore, a strap 100 for hanging a portable item with higher safety can be realized.

[0036] [Second embodiment] FIG. 11 is a perspective view showing a strap 200 for hanging a carried item according to the second embodiment. The strap 200 for hanging a carry-on item includes a string 15 that can be hung around the neck or shoulder. The string 15 has a first connector 25, a second connector 35, a feed ring 45, a D-ring 55, and a strap part 65 attached thereto. "Hanging Cord 15" The hanging string 15 is configured to include string portions 16, 17, and 18 which are flat strings. One end 16a of the string portion 16 is engaged with the feed can 45, passed through the second connector 35, and the other end 16b is engaged with the first connector 25. The engagement structure of the feed can 45, the passage structure of the second connector 35, and the engagement structure of the first connector 35 will be described later. One end 17a of string portion 17 is fastened to first connector 25, and the other end 17b is fastened to D-ring 55. The fastening structure of first connector 25 and the fastening structure of D-ring 55 will be described later. Furthermore, one end 18a of string portion 18 is engaged with D-can 55 and passed through feed can 45, and the other end 18b is engaged with second connector 35. The engagement structure of D-can 55, the passage structure of feed can 45, and the engagement structure of second connector 35 will be described later.

[0037] 《1st connector 25》 FIG. 12 is a perspective view showing the male member 26 and the female member 27 of the first connector 25, and FIG. 13 is a diagram showing the engagement relationship between the male member 26 and the female member 27 of the first connector 25 and the string portion. The first connector 25 is made of plastic and is composed of a male device (connecting piece) 26 and a female device (connecting piece) 27. This first connector 25 is for connecting the other end 16b of the string portion 16 and one end 17a of the string portion 17, and releases the connection when an overload is applied.

[0038] <male tool 26> A knob 26a is provided on the male component 26. An insertion piece 26b is formed to protrude from one side of the knob 26a.

One end 17a of the string portion 17 is passed through the string hole 26d from the back side to the front side, folded back, and immediately thereafter sewn to the back side of the string portion 17.

[0039] <Female Tool 27> A knob 27a is provided on the female device 27. An insertion hole 27b into which the insertion piece 26b of the male device 26 is inserted is formed at one end of the knob 27a. A fitting hole 27c is also formed in the knob 27a, into which the fitting protrusion 26c fits when the insertion piece 26b of the male device 26 is inserted into the insertion hole 27b. The wall constituting the knob portion 27a of the female device 27 has elasticity, and when the insertion piece 26b of the male device 26 is inserted into the insertion hole 27b, it is elastically deformed by the sliding contact of the fitting protrusion 26c, and when the fitting protrusion 26c reaches the fitting hole 27c, the elastic force causes the fitting protrusion 26c to fit into the fitting hole 27c. On the other hand, when a strong force acts to separate the male device 26 and the female device 27, the wall constituting the knob portion 27a is elastically deformed by the sliding contact of the fitting protrusion 26c, and the fitting protrusion 26c comes out of the fitting hole 27c, and the engagement between the fitting protrusion 26c and the fitting hole 27c is released.

[0040] A string hole 27d is formed on the other end side of the tab 27a. The other end 16b of the string portion 16 is passed through the string hole 27d from the back side to the front side, folded back, and immediately sewn to the back side of the string portion 16.

[0041] 《Second connector 35》 FIG. 14 is a perspective view showing the male member 36 and the female member 37 of the second connector 35, and FIG. 15 is a diagram showing the engagement relationship between the male member 36 and the female member 37 of the second connector 35 and the string portion. The second connector 35 is made of plastic and is composed of a male connector (connecting piece) 36 and a female connector (connecting piece) 37. This second connector 35 is for connecting the other end 18b of the string portion 18 and the middle portion of the string portion 16, and releases the connection when an overload is applied.

[0042] <male tool 36> A knob 36a is provided on the male component 36. An insertion piece 36b is formed to protrude from one side of the knob 36a. Moreover, semi-spherical fitting protrusions 36c are formed on both sides of the insertion piece 36b.

[0044] <Female Tool 37> The female device 37 is provided with a knob 37a. An insertion hole 37b into which the insertion piece 36b of the male device 36 is inserted is formed at one end of the knob 37a. The knob 37a also has a fitting hole 37c that fits onto the fitting protrusion 36c when the insertion piece 36b of the male device 36 is inserted into the insertion hole 37b. The wall constituting the knob portion 37a of the female device 37 has elasticity, and when the insertion piece 36b of the male device 36 is inserted into the insertion hole 37b, it is elastically deformed by the sliding contact of the fitting protrusion 36c, and when the fitting protrusion 36c reaches the fitting hole 37c, the elastic force causes the fitting protrusion 36c to fit into the fitting hole 37c. On the other hand, when a strong force acts to separate the male device 36 and the female device 37, the wall constituting the knob portion 37a is elastically deformed by the sliding contact of the fitting protrusion 36c, and the fitting protrusion 36c comes out of the fitting hole 37c, and the engagement between the fitting protrusion 36c and the fitting hole 37c is released.

[0045] A string hole 37d is formed on the other end side of the knob 37a. The string 16, one end 16a of which is engaged with the feed can 45, is passed through the string hole 37d from the back side to the front side and pulled out to the first connector 25 side.

[0046] "Send Can 45" FIG. 16 is a perspective view showing the feed can 45, and FIG. 17 is a diagram showing the engagement relationship between the feed can 45 and the string portion. The feed can 45 is adapted to adjust the length of the hanging cord 15 by moving it. The feed can 45 is made of plastic and is formed in a "day" shape in plan view. Specifically, the feed can 45 is integrally molded of plastic, is rectangular in plan view, and has two string-through holes 45b and 45c formed with a central horizontal bar 45a in between.

[0047] One end 16a of the string portion 16 is locked to the horizontal bar 45a of the feed can 45. That is, one end 16a of the string portion 16 is passed through the string-through hole 45b from the back side to the front side of the feed can 45, and further passed through the string-through hole 45c from the front side to the back side and folded back so as to wrap around the horizontal bar 45a, and is sewn to the back side of the string portion 16 immediately after the folding back.

At that time, the other end 17b of the string portion 17 is sandwiched between the folded-back portion and the string portion 18 and is simultaneously sewn to the back side of the string portion 18.

[0050] 《Strap part 65》 The strap part 65 is provided for suspending the carried item.

[0051] 《Usage method》 The strap 200 for hanging a carry-on item is used by hanging a carry-on item from the strap part 65 and hanging the hanging string 15 around the neck or shoulder in the correct way. Here, the correct way means treating the string portion 16 doubled by the feed can 45 in the same way as a single string portion and hanging it around the neck or shoulder (FIG. 19).

[0052] Effects of the Second Embodiment When the strap 200 for hanging a carry-on item is hung around the neck or shoulder in the correct way (FIG. 19), if the strap 200 for hanging a carry-on item gets caught on an external object or person for some reason, an excessive pulling force is applied to the hanging cord 15. In this case, a large force is applied between the male part 26 and the female part 27 of the first connector 25 such that they are separated from each other. As a result, the engagement between the male part 26 and the female part 27 of the first connector 25 is released, the hanging cord 15 is cut into two, and the hanging cord 15 comes off from the neck or shoulder.

[0053] Also, when the strap 200 for hanging a carry-on item is hung around the neck or shoulder in an irregular manner, that is, when the loop formed by the string portion 16 doubled by the feed can 45 is hung around the neck or shoulder (FIG. 20), if the strap 200 is caught on an external object or person for some reason, an excessive pulling force is applied to the loop. In this case, the feed can 45 moves along the hanging string 15, and the loop expands. When it reaches its limit, a large force is applied between the male member 36 and the female member 37 of the second connector 35, which separates them. As a result, the engagement between the male member 36 and the female member 37 of the second connector 35 is released, the loop is divided into two, and the hanging string 15 comes off from the neck or shoulder.

[0054] In this way, the hanging cord 15 breaks not only when the strap is hung around the neck or shoulder in a proper manner, but also when the strap is hung around the neck or shoulder in an improper manner, thereby realizing a strap 200 for hanging a portable item with higher safety.

[0055] <<Variation>> Although an embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to such an embodiment, and various modifications are possible without departing from the spirit and scope of the present invention.

[0056] For example, in the above embodiment, the first connectors 20, 25 are configured as male and female devices, and the second connectors 30, 35 are configured as male and female devices, but instead of the male and female devices, they may be a pair of connecting pieces that are connected to each other by magnetic force.

[0057] In the above embodiment, the hanging cords 10, 15 are looped and the carry-on item is hung via the D-rings 50, 55 and the strap parts 60, 65 (carry-on item attachment devices), but the carry-on item may be hung via a C-ring, D-ring, round ring, snap hook, string, or other carry-on item attachment device without providing the strap parts 60, 65. The carry-on item may also be hung using a carry-on item attachment device that combines a C-ring or round ring, etc., instead of the D-rings 60, 65, with the strap part 60. Furthermore, one carry-on item (such as a bag) may be hung at both ends of the hanging cord via a carry-on item attachment device such as a D-ring or snap hook.

[0058] In addition, when hanging a carried item (such as a bag) from both ends of the hanging cord, one of the connecting pieces of the first connector may be attached to the carried item without passing through the cord portion of the hanging cord, and the other connecting piece may be attached to at least one end of the hanging cord, so that the first connector connects the hanging cord to the carried item, and when an overload is applied to the first connector, the connection between the hanging cord and the carried item may be severed.
