Description

Technical Field

[0001] This disclosure relates to a fastener, and more particularly to a fastener that is automatically locking and steplessly adjustable. Background Technology

[0002] Please see Figure 1 A conventional buckle 1000 (e.g., a belt) includes a loop 1001 and a pin 1002. The loop 1001 is, for example, a metal ring, and one end of the pin 1002 is pivotally connected to the loop 1001. A rope 1003 has a plurality of spaced-apart holes 1005. A rope 1004 can be fixed to the loop 1001 and connected to the rope 1003. After the rope 1003 passes through the loop 1001, the position of the holes 1005 through which the pin 1002 passes can be determined according to the size of the item encircled by the rope 1003 and 1004. Because the pin 1002 can only pass through the holes 1005 and cannot pass through the rope 1003, and the holes 1005 have a fixed spacing, the user is limited in adjusting the length of the rope 1003 and cannot make fine length adjustments. Summary of the Invention

[0003] The purpose of this disclosure is to provide a fastener to solve at least one of the aforementioned problems.

[0004] This disclosure provides a fastener, comprising: a first fastener, including a first locking portion, two side rod portions, two sliding grooves, and a rope threading space, wherein the side rod portions are spaced apart from each other along a first direction, the first locking portion is connected to one end of the side rod portions along a second direction perpendicular to the first direction, the sliding grooves are respectively recessed into the side rod portions and correspond to each other, and the rope threading space is defined by the first locking portion and the side rod portions; and a second fastener, which is assembled with the first fastener and slides in the sliding grooves along the first direction, and includes a second locking portion, which is disposed along the second direction and located between the side rod portions, and is accommodated in the rope threading space; wherein the second fastener is capable of switching between a locked state and an unlocked state relative to the first fastener, wherein in the locked state, the second locking portion is adjacent to the first locking portion, and in the unlocked state, the second locking portion is away from the first locking portion.

[0005] As described above, the fastener allows a rope to be threaded through it. The rope has a first rope segment, which is threaded through the rope threading space. In the unlocked state, the first rope segment is not clamped by the first locking part and the second locking part. In the locked state, the first rope segment is clamped by the first locking part and the second locking part.

[0006] As described above, the second fastener also includes an operating part and a through hole. The operating part extends outward from the second locking part along the first direction and corresponds to the first locking part. The through hole is defined by the operating part and the second locking part, so that the through hole is located between the operating part and the second locking part and allows the first rope segment to pass through.

[0007] In the aforementioned fastener, the portion of the through hole covered by the first locking part in the locked state is larger than the portion of the through hole covered by the first locking part in the unlocked state.

[0008] As described above, the rope body also defines a bent section and a second rope section. The two ends of the bent section are respectively connected to the first rope section and the second rope section and can abut against the operating part. The second rope section extends out of the buckle.

[0009] In the aforementioned fastener, in the unlocked state, the second rope segment is pulled by a tension applied along the first direction, causing a frictional force between the bent segment and the operating part, thereby driving the second fastener to move, and thus changing from the unlocked state to the locked state.

[0010] As described above, the first fastener further includes at least one fixing part, which is connected to the side rod part along the second direction and spaced apart from the first locking part.

[0011] As described above, the first fastener also includes an outer rod and a through hole. The outer rod is connected to the other end of the side rod along the second direction and is spaced apart from the fixing part. The through hole is defined by the outer rod and the fixing part. After the first rope segment passes through the rope-passing space, it can pass through the through hole, so that the first rope segment abuts against the second locking part and is limited by the outer rod.

[0012] As described above, the first fastener also includes two grooves, which are recessed into the side rod portion and correspond to each other, and are respectively connected to the slide groove. The second fastener also includes two latching portions, which extend outward from opposite sides of the second locking portion and are respectively slidably disposed in the grooves.

[0013] In the aforementioned fastener, in the locked state, the buckle portion abuts against one end of the groove and is limited by the groove, preventing the second fastener from disengaging from the first fastener.

[0014] As described above, each of the side rods has a stop surface, which is located at one end of the slide groove. In the unlocked state, the buckle abuts against the stop surface.

[0015] As described above, the first fastener also includes a horizontal bar portion, which is connected to the side bar portion along the second direction and spaced apart from the first locking portion, and together with the first locking portion and the side bar portion, defines the rope threading space.

[0016] As described above, the first fastener also includes a guide groove, which is recessed in the crossbar portion along the first direction. The second fastener also includes a guide member, which extends outward from the second locking portion and is accommodated in the guide groove, so that the second locking portion can move relative to the crossbar portion along the first direction.

[0017] In the aforementioned fastener, the first locking part and the crossbar part have a gap distance in a third direction perpendicular to the first direction and the second direction, and the second locking part has a thickness in the third direction, the thickness being equal to or less than the gap distance.

[0018] In summary, the present invention utilizes the shearing force generated by the relative movement of the first locking part and the second locking part to automatically lock the rope, allowing for precise length adjustment of the rope and achieving stepless rope adjustment. Furthermore, by using the frictional force generated on the operating part by pulling the rope to move the second fastener, the present invention eliminates the need for a spring, effectively reducing costs.

[0072] Please see Figure 2 , Figure 3 and Figure 4 In the first embodiment, the fastener 100 of this disclosure includes a first fastener 1 and a second fastener 2, which can be assembled with each other. The structure of each component and the connection relationship between them will be described in detail below, wherein some of the drawings show a first direction X, a second direction Y and a third direction Z that are perpendicular to each other.

[0073] The first fastener 1 includes two sliding grooves 10, a first locking part 11, two side rod parts 12, a crossbar part 13, a rope threading space 14, and two grooves 15 (e.g., Figure 5 (As shown) and a fixing part 17. Two grooves 10 are respectively recessed into two side rod parts 12 and correspond to each other. The two side rod parts 12 are spaced apart from each other along a first direction X and each has a stop surface 121, each stop surface 121 being located at one end of each groove 10. A first locking part 11 is generally an elongated plate and is connected to one end of the two side rod parts 12 along a second direction Y, and is adjacent to the top side of the side rod parts 12. A crossbar part 13 is generally an elongated plate and is connected to the two side rod parts 12 along the second direction Y and is spaced apart from the first locking part 11, and is adjacent to the bottom side of the side rod parts 12. Specifically, as Figure 6 As shown, the crossbar portion 13 and the first locking portion 11 are not aligned with each other in the first direction X and the third direction Z, but are misaligned, such that the first locking portion 11 and the crossbar portion 13 have a gap distance D1 in the third direction Z and a gap distance D2 in the first direction X. The crossbar portion 13 is adjacent to the stop surface 121 where it connects to the two side bar portions 12. The rope threading space 14 is defined by the first locking portion 11, the two side bar portions 12 and the crossbar portion 13.

[0074] Please refer to the following: Figure 5 and Figure 6 Two grooves 15 are recessed into the inner sides of the two side rod portions 12 and correspond to each other, and are respectively connected to the sliding grooves 10. A guide groove 16 is recessed into the crossbar portion 13 along the first direction X and faces the rope threading space 14. A fixing portion 17 is connected to the other end of the side rod portion 12 along the second direction Y and is spaced apart from the crossbar portion 13, so that the crossbar portion 13 is located between the fixing portion 17 and the first locking portion 11, and the fixing portion 17 is adjacent to the bottom side of the side rod portion 12.

[0075] The second fastener 2 includes a second locking part 21, an operating part 22, a through hole 23, two latching parts 24, and a guide member 25. The second locking part 21 is generally an elongated plate, disposed along the second direction Y, and has a thickness H in the third direction Z, the thickness H being equal to or less than the spacing distance D1. The operating part 22 extends outward from the second locking part 21 along the first direction X. The through hole 23 is defined by the operating part 22 and the second locking part 21, and is located between the operating part 22 and the second locking part 21, making the operating part 22 generally U-shaped. The two latching parts 24 extend outward from opposite sides of the second locking part 21, protruding from opposite sides of the operating part 22, with one end of the latching part 24 connected to the second locking part 21 and the other end spaced apart from the second locking part 21, such that there is a gap S between the latching part 24 and the second locking part 21. The guide member 25 extends outward from the second locking part 21 and extends along the first direction X.

[0076] The second fastener 2 can be pressed into the gap S by pressing the two latching parts 24 into the gap S, so that the two latching parts 24 are roughly flush with the opposite sides of the operating part 22. At this time, the second fastener 2 can be combined into the first fastener 1 via the sliding groove 10 and along the first direction X, so that the second locking part 21 of the second fastener 2 is accommodated in the rope threading space 14, the guide 25 is accommodated in the guide groove 16, the operating part 22 corresponds to the first locking part 11, and the second locking part 21 is located between the side rod parts 12, until the two latching parts 24 are respectively slid into the two grooves 15. When the two latching parts 24 correspond to the two grooves 15 respectively, the two latching parts 24 will spring back and have a gap S between them and the second locking part 21 again. At this time, a part of the two latching parts 24 slides in the two grooves 15, and the other part of the two latching parts 24 slides together with the two sides of the operating part 22 in the slide groove 10. The two latching parts 24 will be limited by the two grooves 15, so that the second fastener 2 cannot be disengaged from the first fastener 1.

[0077] The following describes the operation of the second fastener 2 relative to the first fastener 1. The present invention's fastener 100, by means of the second fastener 2 sliding in the slide groove 10, two latching portions 24 sliding in the two recesses 15, and a guide member 25 accommodated in the guide groove 16, allows the second fastener 2 to move relative to the first fastener 1 along a first direction X, and can switch between a locked state and an unlocked state. In the locked state, the second locking portion 21 is adjacent to the first locking portion 11, the through hole 23 is approximately covered by the first locking portion 11, and the two latching portions 24 respectively abut against one end of the two recesses 15.

[0078] Please refer to the following: Figure 7 , Figure 8 and Figure 9 A pushing force F2 is applied to the second fastener 2 along the first direction X, causing the second fastener 2 to retract into the first fastener 1 via the slide groove 10. The second locking part 21 can move relative to the crossbar part 13 along the first direction X, and the operating part 22 can move relative to the first locking part 11 along the first direction X until the two latching parts 24 respectively abut against the stop surface 121, and change to the unlocked state. At this time, the second locking part 21 is away from the first locking part 11, and the through hole 23 is not covered by the first locking part 11. That is, the part of the through hole 23 covered by the first locking part 11 in the locked state is larger than the part of the through hole 23 covered by the first locking part 11 in the unlocked state.

[0079] The following describes the use of the buckle 100 in conjunction with ropes 200 and 300. Rope 300 is connected to the fixing part 17. Rope 200 defines a first rope segment 201, a bent segment 202, and a second rope segment 203, with the two ends of the bent segment 202 connected to the first rope segment 201 and the second rope segment 203, respectively. Figure 9As shown, the first rope segment 201 can be sequentially threaded through the through hole 23 and the rope threading space 14 in the unlocked state. At this time, the first rope segment 201 is not yet clamped by the first locking part 11 and the second locking part 21, and can move freely in the through hole 23 and the rope threading space 14. The bent segment 202 abuts against a corner of the operating part 22, and the second rope segment 203 can extend along the bottom surface of the operating part 22 to form a buckle 100.

[0080] In one embodiment, ropes 200 and 300 may be the same rope or different ropes to facilitate use on different items (e.g., clothes, shoes, backpacks, etc.), and this disclosure is not limited thereto. When ropes 200 and 300 are the same rope, the second rope segment 203 extends out of the buckle 100 and wraps around an item before being connected to the fixing part 17.

[0081] Users can be in the unlocked state ( Figure 9 When a pulling force F1 is applied along the first direction X to pull the second rope segment 203, a frictional force is generated between the bent segment 202 and the operating part 22, so that the pulling force F1 can drive the second fastener 2 to move, and can be released from the unlocked state. Figure 9 ) Change to locked state ( Figure 6 ).like Figure 6 As shown, in the locked state, since the thickness H of the second locking part 21 is equal to or less than the distance D1 between the first locking part 11 and the crossbar part 13, the first rope segment 201 can be clamped by the relative corners of the first locking part 11 and the second locking part 21, and the first rope segment 201 is simultaneously adjacent to the bottom surface of the first locking part 11 and the top surface of the second locking part 21. That is, the relative movement of the first locking part 11 and the second locking part 21 will generate a shearing force F3 to automatically lock the first rope segment 201. If the rope 200 needs to be readjusted, simply apply a pushing force F2 to move it from the locked state ( Figure 6 Switch to unlocked state. Figure 9 This releases the shear force F3, allowing the first rope segment 201 to move freely within the through hole 23 and the rope threading space 14, making it easy to adjust the length of the rope 200.

[0082] The above Figure 8 and Figure 9 The unlocked state is shown with the two latches 24 abutting against the stop surface 121, but this disclosure is not limited to this. As long as the first rope segment 201 is not clamped by the first locking part 11 and the second locking part 21, it is in the unlocked state; similarly, the above... Figure 5 and Figure 6The locked state is depicted with the two latches 24 abutting against one end of the two grooves 15, but this disclosure is not limited to this. The first rope segment 201 is in a locked state whenever it is clamped by the first locking part 11 and the second locking part 21. In other words, depending on the size of the rope 200, it may be in a locked or unlocked state when the two latches 24 cannot abut against the stop surface 121 or one end of the two grooves 15.

[0083] Please see Figure 10 , Figure 11 and Figure 12 In the second embodiment, the fastener 100 of this disclosure includes a first fastener 1 and a second fastener 2, which can be assembled with each other. The structure of each component and the connection relationship between them will be described in detail below, wherein some of the drawings show a first direction X, a second direction Y and a third direction Z that are perpendicular to each other.

[0084] The first fastener 1 includes two sliding grooves 10, a first locking part 11, two side rods 12, a crossbar 13, a rope threading space 14, two grooves 15, two fixing parts 17, an outer rod 18, and a through hole 19. The two sliding grooves 10 are respectively recessed into the two side rods 12 and correspond to each other. The two side rods 12 are spaced apart along a first direction X and each has a stop surface 121, with each stop surface 121 corresponding to one end of each sliding groove 10. The first locking part 11 is generally an elongated plate and is connected to one end of the two side rods 12 along a second direction Y, adjacent to the top side of the side rods 12. The crossbar 13 is generally an elongated plate and is connected to the two side rods 12 along the second direction Y, spaced apart from the first locking part 11, and adjacent to the bottom side of the side rods 12. Specifically, as... Figure 14 As shown, the crossbar portion 13 and the first locking portion 11 are not aligned with each other in the first direction X and the third direction Z, but are misaligned, such that the first locking portion 11 and the crossbar portion 13 have a gap distance D1 in the third direction Z and a gap distance D2 in the first direction X. The crossbar portion 13 is adjacent to the stop surface 121 where it connects to the two side bar portions 12. The rope threading space is defined by the first locking portion 11, the two side bar portions 12 and the crossbar portion 13.

[0085] Please refer to the following: Figure 13 and Figure 14Two recesses 15 are respectively recessed into the inner sides of the two side rod portions 12 and correspond to each other, and are respectively connected to the sliding grooves 10. A guide groove 16 is recessed into the crossbar portion 13 along the first direction X and faces the rope threading space 14. Two fixing portions 17 are connected to the other end of the side rod portion 12 at intervals along the second direction Y, and are spaced apart from the crossbar portion 13, such that the crossbar portion 13 is located between one of the fixing portions 17 and the first locking portion 11, and the two fixing portions 17 are adjacent to the bottom side of the side rod portion 12. An outer rod portion 18 is connected to the other end of the side rod portion 12 along the second direction Y, is adjacent to the top side of the side rod portion 12, and is spaced apart from the fixing portion 17. A through hole 19 is defined by the outer rod portion 18 and the fixing portion 17.

[0086] The second fastener 2 includes a second locking part 21, an operating part 22, a through hole 23, two latching parts 24, and a guide member 25. The second locking part 21 is generally an elongated plate, disposed along the second direction Y, and has a thickness H in the third direction Z, the thickness H being equal to or less than the spacing distance D1. The operating part 22 extends outward from the second locking part 21 along the first direction X. The through hole 23 is defined by the operating part 22 and the second locking part 21, and is located between the operating part 22 and the second locking part 21, making the operating part 22 generally U-shaped. The two latching parts 24 extend outward from opposite sides of the second locking part 21, protruding from opposite sides of the operating part 22, with one end of the latching part 24 connected to the second locking part 21 and the other end spaced apart from the second locking part 21, such that there is a gap S between the latching part 24 and the second locking part 21. The guide member 25 extends outward from the second locking part 21 and extends along the first direction X.

[0087] The second fastener 2 can be pressed into the gap S by pressing the two latching parts 24 into the gap S, so that the two latching parts 24 are roughly flush with the opposite sides of the operating part 22. At this time, the second fastener 2 can be combined into the first fastener 1 via the sliding groove 10 and along the first direction X, so that the second locking part 21 of the second fastener 2 is accommodated in the rope threading space 14, the guide 25 is accommodated in the guide groove 16, the operating part 22 corresponds to the first locking part 11, and the second locking part 21 is located between the side rod parts 12, until the two latching parts 24 are respectively slid into the two grooves 15. When the two latching parts 24 correspond to the two grooves 15 respectively, the two latching parts 24 will spring back and have a gap S between them and the second locking part 21 again. At this time, a part of the two latching parts 24 slides in the two grooves 15, and the other part of the two latching parts 24 slides together with the two sides of the operating part 22 in the slide groove 10. The two latching parts 24 will be limited by the two grooves 15, so that the second fastener 2 cannot be disengaged from the first fastener 1.

[0088] The following describes the operation of the second fastener 2 relative to the first fastener 1. The present invention's fastener 100, by means of the second fastener 2 sliding in the slide groove 10, two latching portions 24 sliding in the two recesses 15, and a guide member 25 accommodated in the guide groove 16, allows the second fastener 2 to move relative to the first fastener 1 along a first direction X, and can switch between a locked state and an unlocked state. In the locked state, the second locking portion 21 is adjacent to the first locking portion 11, the through hole 23 is approximately covered by the first locking portion 11, and the two latching portions 24 respectively abut against one end of the two recesses 15.

[0089] Please refer to the following: Figure 16 , Figure 17 and Figure 18 A pushing force F2 is applied to the second fastener 2 along the first direction X, causing the second fastener 2 to retract into the first fastener 1 via the slide groove 10. The second locking part 21 can move relative to the crossbar part 13 along the first direction X, and the operating part 22 can move relative to the first locking part 11 along the first direction X until the two latching parts 24 respectively abut against the stop surface 121, and change to the unlocked state. At this time, the second locking part 21 is away from the first locking part 11, and the through hole 23 is not covered by the first locking part 11. That is, the part of the through hole 23 covered by the first locking part 11 in the locked state is larger than the part of the through hole 23 covered by the first locking part 11 in the unlocked state.

[0090] The following describes the use of the buckle 100 in conjunction with ropes 200 and 300. Rope 300 is connected to one of the two fixing parts 17 and can be limited by the other fixing part 17. Rope 200 defines a first rope segment 201, a bent segment 202, and a second rope segment 203, with the two ends of the bent segment 202 connected to the first rope segment 201 and the second rope segment 203, respectively. Figure 18 As shown, the first rope segment 201 can be sequentially threaded through the through hole 23 and the rope threading space 14 in the unlocked state. At this time, the first rope segment 201 is not yet clamped by the first locking part 11 and the second locking part 21, and can move freely in the through hole 23 and the rope threading space 14. The bent segment 202 abuts against a corner of the operating part 22, and the second rope segment 203 can extend along the bottom surface of the operating part 22 to form a buckle 100.

[0091] In one embodiment, ropes 200 and 300 may be the same rope or different ropes to facilitate use on different items (e.g., clothes, shoes, backpacks, etc.), and this disclosure is not limited thereto. When ropes 200 and 300 are the same rope, the second rope segment 203 extends out of the buckle 100 and wraps around an item before being connected to the fixing part 17.

[0092] Users can be in the unlocked state ( Figure 18When a pulling force F1 is applied along the first direction X to pull the second rope segment 203, a frictional force is generated between the bent segment 202 and the operating part 22, so that the pulling force F1 can drive the second fastener 2 to move, and can be released from the unlocked state. Figure 18 ) Change to locked state ( Figure 14 ).like Figure 14 As shown, in the locked state, since the thickness H of the second locking part 21 is equal to or less than the distance D1 between the first locking part 11 and the crossbar part 13, the first rope segment 201 can be clamped by the relative corners of the first locking part 11 and the second locking part 21, and the first rope segment 201 is simultaneously adjacent to the bottom surface of the first locking part 11 and the top surface of the second locking part 21. That is, the relative movement of the first locking part 11 and the second locking part 21 will generate a shearing force F3 to automatically lock the first rope segment 201. If the rope 200 needs to be readjusted, simply apply a pushing force F2 to move it from the locked state ( Figure 14 Switch to unlocked state. Figure 18 This releases the shear force F3, allowing the first rope segment 201 to move freely within the through hole 23 and the rope threading space 14, making it easy to adjust the length of the rope 200.

[0093] In the locked state, such as Figure 15 As shown, after passing through the rope-threading space 14, the first rope segment 201 can be threaded through the through hole 19, so that the first rope segment 201 abuts against the top surface of the second locking part 21 and is limited by the outer rod part 18, thereby effectively storing the first rope segment 201.

[0094] The above Figure 17 and Figure 18 The unlocked state is shown with the two latches 24 abutting against the stop surface 121, but this disclosure is not limited to this. As long as the first rope segment 201 is not clamped by the first locking part 11 and the second locking part 21, it is in the unlocked state; similarly, the above... Figure 13 and Figure 14 The locked state is depicted with the two latches 24 abutting against one end of the two grooves 15, but this disclosure is not limited to this. The first rope segment 201 is in a locked state whenever it is clamped by the first locking part 11 and the second locking part 21. In other words, depending on the size of the rope 200, it may be in a locked or unlocked state when the two latches 24 cannot abut against the stop surface 121 or one end of the two grooves 15.

[0095] In one embodiment, the first fastener 1 and the second fastener 2 may be integrally formed and elastic plastic parts, but this disclosure is not limited thereto.

[0096] In summary, the present invention utilizes the shearing force generated by the relative movement of the first locking part and the second locking part to automatically lock the rope, allowing for precise length adjustment of the rope and achieving stepless rope adjustment. Furthermore, by using the frictional force generated on the operating part by pulling the rope to move the second fastener, the present invention eliminates the need for a spring, effectively reducing costs.
