Description

Technical Field

[0001] This disclosure provides a buckle, and more particularly relates to a buckle adjustable for four rope ends. Background Technology

[0002] Existing rope buckles, such as those disclosed in CN217390120U, are mostly two-piece structures, including male and female buckles that are assembled together. The male and female buckles can clamp and fix the rope through the rebound force of the elastic section.

[0003] However, existing rope buckles can only adjust two rope ends. If more than two rope ends (such as four rope ends) need to be adjusted, the number of rope buckles must be increased, which not only takes up space but is also inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a fastener to solve at least one of the above-mentioned problems.

[0005] This disclosure provides a fastener for threading two first rope tails and two second rope tails. The fastener includes: a first fastener comprising two first outer channels and a first inner channel, the first inner channel being located between the first outer channels; and a second fastener, which is assembled with the first fastener and comprises two second outer channels and two second inner channels, the second outer channels being spaced apart from each other and respectively connected to the first outer channels, the second inner channels being spaced apart from each other and connected to the first inner channels, and the second inner channels being located between the second outer channels; wherein the first rope tails are threaded through the first inner channels and the second inner channels, and the second rope tails are threaded through the first outer channels and the second outer channels.

[0006] As described above, the first fastener further includes two plates, two first inner connectors, and two first outer connectors. The plates are arranged in parallel with each other at intervals. The first inner connectors are disposed between the plates and together with the plates define the first inner channel. The first outer connectors are disposed between the plates and together with the plates and the first inner connectors define the first outer channel. The first inner connectors are located between the first outer connectors.

[0007] As described above, the second fastener also includes a base and two wings, with the second inner channel extending through the base, the wings extending outward from opposite sides of the base, and the second outer channel extending through the wings.

[0008] As described above, each of the first inner connecting bodies has a first inner tooth portion facing the first inner channel and corresponding to each other, each of the first outer connecting bodies has a first outer tooth portion facing the first outer channel, and the seat has two second outer tooth portions facing the first outer tooth portion.

[0009] As described above, the second fastener also includes two spring pieces and a gear. The spring pieces extend outward from the base body at intervals and are located corresponding to the first inner channel. The gear is movably disposed between the spring pieces and is located corresponding to the first inner tooth portion.

[0010] As described above, each of the spring pieces has a cylinder, and the gear has opposing recesses, with the cylinders respectively disposed in the recesses, and the cross-sectional area of ​​the recesses being greater than the cross-sectional area of ​​the cylinders.

[0011] As described above, the second fastener can switch between a released state and a locked state relative to the first fastener. In the locked state, the gear is adjacent to the first inner tooth portion, the second outer tooth portion is adjacent to the first outer tooth portion, the first rope tail is clamped by the gear and the first inner tooth portion, and the second rope tail is clamped by the first outer tooth portion and the second outer tooth portion. In the released state, the gear moves away from the first inner tooth portion, allowing the first rope tail to move in the first inner channel and the second inner channel, and the second outer tooth portion moves away from the first outer tooth portion, allowing the second rope tail to move in the first outer channel and the second outer channel.

[0012] As described above, when the buckle is in the locked state, an external force is applied to pull the first rope tail, causing the first rope tail to move from the first inner channel to the second inner channel, while simultaneously driving the gear closer to the seat. At this time, the first rope tail accumulates a tight force. When the external force is removed, the tight force causes the first rope tail to drive the gear away from the seat and close to the first inner tooth, so that the first rope tail is clamped by the gear and the first inner tooth.

[0013] The aforementioned fastener also includes a third fastener and an elastic member. The third fastener is fixed to the first fastener, and the elastic member is disposed between the third fastener and the second fastener, and constantly provides an elastic force that tends to keep the second fastener in the locked state.

[0014] As described above, the first fastener also includes a plurality of slide rails formed on the plate, and the second fastener also includes a plurality of slide channels recessed in the base and the wing, for the slide rails to slide therein.

[0015] As described above, the first fastener also includes two limiting grooves, which are respectively recessed into the plate and used to limit the second fastener.

[0016] In summary, the buckle disclosed herein allows for segmented adjustment of the tension of the inner and outer rope ends without interference between them. Furthermore, the buckle can be operated with one hand, offering ease of use. Attached Figure Description

[0059] Please see Figures 1 to 5 The fastener 100 disclosed herein includes a first fastener 1, a second fastener 2, a third fastener 3, and an elastic element 4. The first fastener 1 and the second fastener 2 can be assembled with each other, the third fastener 3 is fixedly connected to the first fastener 1, and the elastic element 4 is disposed between the second fastener 2 and the third fastener 3. The structure of each component and the connection relationship between them will be described in detail below.

[0060] In this embodiment, the buckle 100 can be installed on an item, such as a shoe with double laces, but this disclosure is not limited thereto. The item can also be clothing fabric, cuffs, coat hoods, leather goods, plastic shells, protective gear, backpacks, handbags, helmets, raincoats, etc.

[0061] The first fastener 1 includes two plates 11, two first inner connecting bodies 12, two first outer connecting bodies 13, two first outer channels 14, one first inner channel 15, multiple slide rails 16 and 17, two limiting grooves 18, and two snap-fit ​​holes 19.

[0062] The sheet bodies 11 are generally square plates, arranged parallel to each other at intervals. The first inner connectors 12 are disposed at intervals between the sheet bodies 11, and together with the sheet bodies 11, they surround and define the first inner channel 15. The first outer connectors 13 are disposed at intervals between the sheet bodies 11, and are located outside the first inner connectors 12, that is, the first inner connectors 12 are located between the first outer connectors 13, so that the first outer connectors 13, the sheet bodies 11, and the first inner connectors 12 together surround and define the first outer channel 14, so that the first inner channel 15 is located between the first outer channels 14.

[0063] Each first inner connector 12 has a first inner tooth 121, which faces the first inner channel 15 and corresponds to each other. Each first outer connector 13 has a first outer tooth 131, which faces the first outer channel 14. The slide rails 16 are formed at intervals on the inner side of the sheet 11, for example, two slide rails 16 are formed on the inner side of each sheet 11. The slide rails 17 are provided on the side of the sheet 11 and adjacent to the first outer connectors 13, for example, one slide rail 17 is formed on each opposite side of each sheet 11. The limiting grooves 18 are respectively recessed on the inner side of the sheet 11 and correspond to the first inner channel 15. The snap-fit ​​holes 19 are respectively formed through the sheet 11 and located between the slide rails 16.

[0064] The second fastener 2 includes a body 21, two wings 22, two second outer channels 23, two second inner channels 24, a receiving space 25, two spring clips 26, a gear 27, and multiple slides 28 and 29.

[0065] The seat 21 is generally U-shaped and is located between the plates 11. It has a recess 211 and two second external teeth 212, which are located on opposite sides of the seat 21 and face the first external teeth 131. The wing 22 is generally L-shaped and extends outward from opposite sides of the seat 21 to correspond to the second external teeth 212 and cover opposite sides of the first fastener 1. The outer surface of the wing 22 may have multiple ribs for the user to grip and move the second fastener 2. The second outer channels 23 are formed through the wing 22 and connect to the first outer channels 14. The second inner channels 24 are formed through the seat 21 and spaced apart from each other, and connect to the first inner channels 15. The second outer channels 23 and the second inner channels 24 are not connected to each other, and the second inner channels 24 are located between the second outer channels 23. The accommodating space 25 is defined by the seat 21 and communicates with the recess 211, and is located between and not communicated with the second inner channel 24.

[0066] The spring pieces 26 are roughly U-shaped pieces, extending outward from the base 21 at intervals, and each has a cylinder 261. The spring pieces 26 are located within the limiting grooves 18 and are limited by the limiting grooves 18. The gear 27 has a recess 271 on each of its two opposite surfaces, and a plurality of protrusions are arranged around its periphery. The cylinders 261 are respectively disposed in the recesses 271, and the cross-sectional area of ​​the recesses 271 is larger than the cross-sectional area of ​​the cylinders 261, so that the gear 27 is movably disposed between the spring pieces 26 and will not detach from the spring pieces 26, and is located between the first internal teeth 121. Under the limitation of the cylinders 261, the gear 27 can move in any direction relative to the spring pieces 26 and has a certain degree of movable space. The slide rails 28 are recessed at intervals on opposite surfaces of the base 21 and adjacent to the second external tooth 212. For example, two slide rails 28 are formed on one surface, and slide rails 16 are slidably disposed therein. The slide rails 29 are recessed at intervals on the wing 22. For example, two slide rails 29 are formed on one wing 22, and slide rails 17 are slidably disposed therein.

[0067] The third fastener 3 is fixed to the first fastener 1 and located in the receiving space 25 of the second fastener 2. The third fastener 3 has two snap-fit ​​portions 31 and a receiving hole 32. The snap-fit ​​portions 31 are respectively snapped into the snap-fit ​​holes 19, and the receiving hole 32 faces the receiving space 25. The elastic member 4 is disposed between the third fastener 3 and the second fastener 2 and is located in the receiving space 25. Its two ends are respectively received in the receiving hole 32 and the recess 211. The elastic member 4 is used to constantly provide an elastic force that tends to keep the second fastener 2 in a locked state. Figure 6 In one embodiment, the elastic element 4 may be a compression spring.

[0068] Please see Figure 6 and Figure 8 The mutual combination of the slide rails 16 and 17 and the slide channels 28 and 29 allows the second fastener 2 to slide relative to the first fastener 1, so that the second fastener 2 can be in a locked state relative to the first fastener 1. Figure 6 ) and a released state ( Figure 8 The buckle 100 can accommodate two first rope tails 5 and two second rope tails 6. The two first rope tails 5 are passed through the first inner channel 15 and then through the second inner channel 24. The two second rope tails 6 are passed through the first outer channel 14 and then through the second outer channel 23. In one embodiment, the two first rope tails 5 can be the same rope or different ropes; similarly, the two second rope tails 6 can be the same rope or different ropes. Taking a shoe with double laces as an example, the first rope tail 5 is one layer of laces, and the second rope tail 6 is the other layer of laces.

[0069] like Figure 6 As shown, in the locked state, gear 27 is adjacent to the first internal tooth portion 121 and away from the seat body 21 (the cylinder 261 abuts against one end of the recess 271 adjacent to the seat body 21), so that the first rope tail 5 is clamped by gear 27 and the first internal tooth portion 121, that is, two first rope tails 5 are clamped by the first internal tooth portion 121 on both sides of gear 27. The second external tooth portion 212 is adjacent to the first external tooth portion 131, so that the second rope tail 6 is clamped by the first external tooth portion 131 and the second external tooth portion 212.

[0070] Please see Figure 7 When locked, an external force F2 can be applied to pull the first rope tail 5, causing it to abut against the first inner connecting body 12 and move from the first inner channel 15 to the second inner channel 24. Simultaneously, this drives the gear 27 closer to the seat 21 (the cylinder 261 abuts against the end of the recess 271 away from the seat 21). This means the first rope tail 5 is not completely clamped by the gear 27 and the first inner tooth 121 (the orientation of the first inner tooth 121 facilitates the external force F2 pulling the first rope tail 5). At this time, the buckle 100 approaches the object, and the first rope tail 5 accumulates a pressing force T. When the external force F2 is removed, the pressing force T causes the first rope tail 5 to move the gear 27 away from the seat 21 and closer to the first inner tooth 121 (returning to...). Figure 6In the locked state, the first rope tail 5 is clamped by the gear 27 and the first internal tooth 121. Similarly, when in the locked state, an external force F1 can be applied to pull the second rope tail 6, causing the second rope tail 6 to abut against the first external connector 13 and move from the first external channel 14 to the second external channel 23. The second rope tail 6 will not be clamped by the first external tooth 131 and the second external tooth 212 (the orientation of the first external tooth 131 and the second external tooth 212 facilitates the external force F1 to pull the second rope tail 6). In other words, the first rope tail 5 and the second rope tail 6 can be adjusted in tightness respectively. For example, when the second rope tail 6 is tightened, the seat body 21 and the wing body 22 are stationary relative to the first fastener 1, and the first rope tail 5 can still be adjusted in tightness through the movable gear 27. For example, when the first rope tail 5 is tightened, the gear 27 is stationary relative to the first fastener 1, while the seat body 21 and the wing body 22 can still move relative to the gear 27. Therefore, the second rope tail 6 can still be adjusted in tightness through the movable seat body 21 and the wing body 22.

[0071] Please see Figure 8 To release the locking state, a pulling force F3 can be applied to the second fastener 2, causing it to move away from the first fastener 1 and switch to the released state. In the released state, the elastic element 4 is compressed by the second fastener 2 and the third fastener 3. The gear 27, driven by the cylinder 261, moves away from the first internal tooth portion 121, allowing the first rope tail 5 to move freely within the first inner channel 15 and the second inner channel 24, free from the clamping of the gear 27 and the first internal tooth portion 121. The second external tooth portion 212 moves away from the first external tooth portion 131, allowing the second rope tail 6 to move freely within the first outer channel 14 and the second outer channel 23, free from the clamping of the first external tooth portion 131 and the second external tooth portion 212. When the pulling force F3 is removed, the second fastener 2, through the rebound of the elastic element 4, changes from the released state to the locked state, and clamps the first rope tail 5 and the second rope tail 6 again.

[0072] In summary, the buckle disclosed herein allows for segmented adjustment of the tension of the inner and outer rope ends without interference between them. Furthermore, the buckle can be operated with one hand, offering ease of use.
