The following embodiments will further detail the related technical content of the present invention, but the disclosed content is not used to limit the protection scope of the present invention.

[0028] It should be understood that although terms such as "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another, or one signal from another. Additionally, the term "or" used herein should, depending on the actual situation, possibly include any one or a combination of more of the associated listed items.

[0029] Please refer to Figures 1 to 10As shown, this is an embodiment of the present invention. This embodiment discloses a detachable cord system 100, which can more easily fix / detach a wearable 200 to fix / regulate the wearable 200 to a predetermined position. The detachable cord system 100 can be applied to backpack cords or other wearable objects, etc., and the present invention does not limit this here.

[0030] As Figure 2 and Figure 3 As shown, the detachable cord system 100 includes: a fixed-end fastener 1, a cord 2, a release-end fastener 3, and an open fastener 4. Specifically, in this embodiment, the detachable cord system 100 folds the cord 2, places it in the fixed-end fastener 1, then passes both ends of the cord 2 through the release-end fastener 3, and finally fits and fixes the two tails of the cord 2 in the open fastener 4. The features of each component and the connection relationship between each component will be described in detail below in sequence.

[0031] As Figure 3 and Figure 4 As shown, the fixed-end fastener 1 in this embodiment includes a base 11, a stop rib 12 connected to the base 11, and two limit ribs 13 connected to the base 11, but not limited thereto. For example, in other embodiments not shown in the present invention, the fixed-end fastener 1 may not include the two limit ribs 13.

[0032] Wherein, the base 11 has an annular frame 111 and a partition rib 112 located inside the annular frame 111. The two ends of the partition rib 112 are (vertically) connected to the inner edge of the annular frame 111 to jointly form two cord holes 113.

[0033] Furthermore, in this embodiment, the annular frame 111 is further defined as a rectangular frame, and the partition rib 112 is approximately located at the center of the annular frame 111, so that the shapes of the two cord holes 113 are approximately the same and each is a rectangular perforation. However, the shape of the base 11 can be adjusted and changed according to design requirements, and the present invention does not limit this here.

[0034] The stop rib 12 is connected to the outer edge of the annular frame 111 of the base 11, and the stop rib 12 and the partition rib 112 are arranged in a row along a height direction H. That is to say, the stop rib 12 is vertically connected to the center of the top edge of the annular frame 111 and is spaced from the two limit ribs 13 respectively.

[0035] In this embodiment, the two limiting ribs 13 are respectively and vertically connected to two ends of the top edge of the annular frame 111, and two limiting spaces S can be defined between the stop rib 12 and the two limiting ribs 13. The two limiting spaces S respectively correspond to the two rope passing holes 113 along the height direction H. Further, the two limiting ribs 13 are respectively located on opposite sides of the stop rib 12 at intervals, so that one of the limiting spaces S is jointly defined between each limiting rib 13 and the stop rib 12.

[0036] More specifically, the stop rib 12 is recessed with a rope receiving groove 121, so that the shape of the stop rib 12 presents a hook shape in this embodiment. Further, a height D1 of the rope receiving groove 121 in the height direction H is approximately equal to an outer diameter of the rope belt 2. In addition, a distance D2 less than the outer diameter of the rope belt 2 is separated between the end of each limiting rib 13 and the end of the stop rib 12. According to the above, further defining the height D1 and the distance D2 in this embodiment can make the rope belt 2 more stably placed in the fixed end fastener 1.

[0037] As Figure 2 and Figure 3 shown, the rope belt 2 is an elastic rope belt in this embodiment and has the characteristics of being compressible and expandable, so that it can be more easily placed into the fixed end fastener 1, but it can be adjusted and changed according to design requirements, and the present invention does not limit this here. For example, in other embodiments not shown in the present invention, the rope belt 2 may not have elasticity according to design requirements.

[0038] The rope belt 2 includes two adjusting sections 21, two rope tail sections 22 respectively connected to the two adjusting sections 21, and a folding section 23 connecting the two adjusting sections 21. It should be additionally noted that the rope belt 2 is divided into the above-mentioned multiple sections according to its relative positions with respect to the fixed end fastener 1, the release end fastener 3, and the open fastener 4, but the present invention is not limited thereto.

[0039] Further, the two adjusting sections 21 are connected by the folding section 23, and two ends of the folding section 23 are respectively connected to the two adjusting sections 21. In addition, the two rope tail sections 22 are respectively connected to one end of the two adjusting sections 21, and a knot 24 is formed at each rope tail section 22 away from the corresponding adjusting section 21.

[0040] Specifically, as Figure 5 and Figure 6As shown, between the cord 2 and the fixed-end fastener 1, the folded section 23 passes through the two cord-passing holes 113 of the fixed-end fastener 1 respectively. Thus, when the folded section 23 passes through the two cord-passing holes 113 respectively, the folded section 23 and the fixed-end fastener 1 together form a buckle structure.

[0041] Furthermore, the buckle structure is sleeved on the stop rib 12 through the folded section 23 so that the wearable 200 can be fixed; or, the buckle structure can also be separated from the stop rib 12 through the folded section 23 so that the wearable 200 can be adjusted. More specifically, after passing through the two cord-passing holes 113, the folded section 23 can make the cord 2 form a 180-degree turn through the inner wall of the annular frame 111 of the fixed-end fastener 1, and then the folded section 23 is sleeved on the stop rib 12.

[0042] For example, when the folded section 23 is not sleeved on the stop rib 12 (that is, when the folded section 23 is separated from the stop rib 12), the buckle structure will be in an installation position P1. In addition, when the buckle structure is in the installation position P1, the folded section 23 is used to pass through a first installation ring 200a of the wearable 200.

[0043] After the buckle structure is in the installation position P1, the first installation ring 200a can further be sleeved on the stop rib 12 through the folded section 23 of the buckle structure, so that the buckle structure and the first installation ring 200a are looped and fixed to each other, and the buckle structure is in a fixed position P2.

[0044] Furthermore, when the buckle structure is in the fixed position P2, the folded section 23 is sleeved on the stop rib 12 and located within the two limiting spaces S, and the folded section 23 is sleeved on the stop rib 12 and partially embedded in the cord-containing groove 121 recessed in the stop rib 12. That is to say, the cord-containing groove 121 recessed in the stop rib 12 is located on the side away from the first installation ring 200a.

[0045] As Figure 2 、 Figure 3 and Figure 7 shown, after the cord 2 extends out of the cord-passing hole 113 from the folded section 23, the cord 2 will continue to enter the release-end fastener 3. Among them, the cord 2 passes through the release-end fastener 3 through the two adjustment sections 21 it contains.

[0046] The release end fastener 3 is formed with an adjusting portion 31 and a fastening portion 32 connected to the adjusting portion 31. Wherein, the fastening portion 32 is used to detachably fasten to a second mounting ring 200b of the wearable member 200.

[0047] The cord 2 passes through the adjusting portion 31 through the two adjusting sections 21. Wherein, the adjusting portion 31 has two turning channels 311, and after the two adjusting sections 21 respectively pass through the two turning channels 311, the cord 2 will finally enter the open fastener 4 with the cord tail section 22. Further, the two turning channels 311 make the open fastener 4 located between the release end fastener 3 and the fixed end fastener 1, and the open fastener 4 is adjacent to the adjusting portion 31 of the release end fastener 3.

[0048] In this embodiment, as Figures 8 to 10 shown, the open fastener 4 generally presents a rectangular structure, and the open fastener 4 is a one-piece structure formed integrally, but its shape can be adjusted and changed according to design requirements, and the present invention does not limit this here. Wherein, the open fastener 4 includes two cord passing channels 41 and at least two through holes 42 respectively communicating with the two cord passing channels 41.

[0049] In this embodiment, each of the cord passing channels 41 generally presents a circular channel, but its shape can be adjusted and changed according to design requirements, and the present invention does not limit this here. Further, both of the two cord passing channels 41 have a first opening 411 and a second opening 412 located on the opposite side of the first opening 411. That is to say, the first opening 411 and the second opening 412 are respectively located at opposite ends of the open fastener 4 (or the corresponding cord passing channel 41).

[0050] Wherein, the first openings 411 of the two cord passing channels 41 communicate with each other, while the second openings 412 of the two cord passing channels 41 are separated from each other.

[0051] Further, in this embodiment, the open fastener 4 is further formed with a partition wall 43 separating the two cord passing channels 41, and the partition wall 43 is formed with a notch 431 communicating with the two first openings 411, and the two cord passing channels 41 communicate with each other through the notch 431.

[0052] In this embodiment, the detachable cord system 100 further includes a cover 5, and the notch 431 can be used to accommodate the cover 5. That is to say, the cover 5 is detachably inserted and fixed in the notch 431 of the open fastener 4, and the cover 5 can completely cover the two first openings 411 of the two cord channels 41. In other words, the cover 5 can be generally fixed within the notch 431 and the two first openings 411.

[0053] In addition, each cord channel 41 of the open fastener 4 communicates with at least one through hole 42. Further, in each cord channel 41, at least one through hole 42 is located between the first opening 411 and the second opening 412.

[0054] In this embodiment, each through hole 42 is a rectangular through hole. The number of at least two through holes 42 of the open fastener 4 is further limited to four, and each cord channel 41 communicates with two through holes 42 on its opposite sides respectively. More specifically, the hole walls of the two through holes 42 communicating with each cord channel 41 are aligned with each other along a thickness direction T, but it can be adjusted and changed according to actual needs, and the present invention does not limit this here.

[0055] For example, in other embodiments not shown in the present invention, each cord channel 41 may also only communicate with one through hole 42 respectively. Among them, the two through holes 42 communicating with the two cord channels 41 may be arranged adjacent to each other and on the same side of the open fastener 4, and no holes are formed on the other side of the open fastener 4. The two through holes 42 of the open fastener 4 may also be located on opposite sides and be arranged in a staggered configuration.

[0056] To prevent each cord tail section 22 from easily detaching from the open fastener 4 due to extrusion, the following will continue to describe how to more stably fix each cord tail section 22 in the open fastener 4.

[0057] The two cord tail sections 22 included in the cord 2 are respectively accommodated and limited within the two cord channels 41, and any one cord tail section 22 can move between the two first openings 411, but cannot move between the two second openings 412.

[0058] It should be noted that the structural configurations between the two rope tail segments 22 and the two rope threading channels 41 are substantially the same, so for ease of description, the following description only introduces the connection relationship between one of the rope tail segments 22 and the corresponding rope threading channel 41, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the connection relationship between any one of the rope tail segments 22 and the corresponding rope threading channel 41 may be slightly different from the connection relationship between the other rope tail segment 22 and the corresponding rope threading channel 41.

[0059] Specifically, in this embodiment, the rope tail section 22 is pulled into the rope threading channel 41 of the open buckle 4 from the first opening 411 of the open buckle 4, and each rope tail section 22 is arranged in the corresponding rope threading channel 41 with the rope knot 24. The rope knot 24 has the characteristics of being compressible and expandable, so that the rope tail section 22 including the rope knot 24 can be pulled into the open buckle 4 more easily.

[0060] In addition, a portion of the knot 24 is placed in at least one of the through holes 42 of the rope passage 41. That is, in this embodiment, the knot 24 of each rope tail section 22 is placed in the corresponding rope passage 41 and embedded and fixed in the corresponding two through holes 42, but it can be adjusted and changed according to design requirements, and the present invention is not limited here.

[0061] Furthermore, the outer diameter of the knot 24 is larger than the inner diameter of the first opening 411 of the rope passage 41 , so that after the knot 24 is pulled into the open fastener 4 , it is not easy to escape from the open fastener 4 through the first opening 411 .

[0062] In addition, the outer diameter of the knot 24 is larger than the inner diameter of the corresponding rope passage 41 and also larger than the inner diameter of the corresponding second opening 412 , so that the knot 24 is not easily separated from the open buckle 4 from the second opening 412 .

[0063] [Technical Effects of Embodiments of the Invention]

[0064] To summarize, the detachable strap system and the strap assembly disclosed in the embodiment of the present invention can, through the mutual cooperation of the fixed end buckle and the strap (the folding section is sleeved and engaged in the rope receiving groove of the stop rib / separated from the rope receiving groove of the stop rib), be fixed to the fixed end buckle / separated from the fixed end buckle by simply loading and unloading the strap when the position of the wearable item needs to be adjusted, so as to solve the problem that the strap was fixed by knotting in the past, and it was difficult to disassemble the strap when adjusting the position of the wearable item.
