Press-type rotary cord fastener

Abstract

The press-type rotary lace fastener includes a fixed base (10) installed on the upper, tongue, heel, clothing and hat, or bag, on the fixed base (10), on which a winding base (20) is installed, and on which a winding reel (30) is installed in a lace storage chamber (21) within the winding base (20), on which a return spring (40), a drive wheel (50), and a rotating cover (60) are sequentially installed, on which the rotating cover (60) drives the winding reel (30) to rotate within the winding base (20) via the drive wheel (50), and a button (70) is installed on the rotating cover (60), and when the button (70) is pressed, it acts on the drive wheel (50) and compresses the return spring (40), thereby separating or returning the rotating cover (60) and the drive wheel (50). The rotating lid (60) is driven by the drive wheel (50) to rotate the winding reel (30) within the winding base (20). When the button (70) is pressed, it acts on the drive wheel (50) and compresses the return spring (40), thereby separating or returning the drive connection between the rotating lid (60) and the winding reel (30). This allows the winding lock state of the cord stopper to be switched on or off using only the button (70). Consequently, the button (70) can be pressed in cooperation with both feet or other ground objects, freeing up both hands and eliminating the need to bend at the waist, thus improving the user experience.

Description

Technical Field

[0001] The present disclosure relates to the technical field of string fasteners, specifically a pressing and rotating type string fastener.

Background Art

[0002] String fasteners are mainly used in shoes, clothing, backpacks, rehabilitation products, etc., and are used to tighten or loosen strings. String fasteners are widely used. These products provide a portable experience for many users, but there are still some problems with existing manual tension adjustment buttons during use.

[0003] For example, the Chinese patent with publication number CN108791997A provides a string fastener device including a rotor and a stator. The stator includes a sleeve, the rotor includes an upper cover and a string winding groove installed in order from top to bottom. Claws are installed on the sleeve, and teeth are correspondingly installed on the upper cover. Gear structures are installed on both the rotor and the stator, and through the gear structure, the meshing or separation connection between the claws and the teeth is realized. Since the gear structure is adopted, when the upper cover is pushed, the upper cover fits and is connected to the string winding groove, and the teeth of the upper cover mesh with the claws of the sleeve. At this time, the string fastener system is in the first gear state. When the rotor is rotated in the forward direction, the string is wound into the string winding groove in the tightening direction. In this gear state, the rotor cannot reverse, so the function of tightening the string is realized. When the upper cover is removed, the claws and the teeth are disengaged, so that the rotor is no longer restricted in one direction, and the connection between the upper cover of the rotor and the string winding groove is disengaged. At this time, both the upper cover and the string winding groove can rotate freely in both forward and reverse directions, thereby realizing automatically loosening the string. Also, for example, the Chinese patent with publication number CN218635442U provides a string fastener. When loosening the shoelace, first pull the cover up and then rotate the cover to loosen the shoelace. After pressing the cover, the claw wheel piece and the one-way tooth mesh. When the user rotates the cover, the cover can only be rotated in one direction, so as to wind and tighten the shoelace on the surface of the winding reel.

[0004] The above-mentioned cord fasteners typically employ a radially toggleable cover, and achieving gear switching between loosening and tightening the cord fastener requires the user to bend over and operate it manually, regardless of whether they are loosening or reeling in the cord. Furthermore, the use of a clutch mechanism tends to make the structure complex and prone to breakage with repeated pulling. [Overview of the Initiative]

[0005] The purpose of this disclosure is to provide a press-and-rotate type cord fastener that solves the inconvenience of existing cord fasteners, which require the user to bend over and manually operate the device to loosen or tighten the cord.

[0006] To achieve the above objectives, this disclosure provides the following technical solutions.

[0007] The press-and-rotate lace fastener includes a fixed base installed on the upper, tongue, heel, clothing and hat, or bag, the fixed base having a winding base installed on it, a winding reel installed in the lace storage chamber within the winding base, the winding reel having a return spring, a drive wheel and a rotating cover installed sequentially on it, the rotating cover driving the winding reel to rotate within the winding base by the drive wheel, the rotating cover having a button installed on it, the button acting on the drive wheel to compress the return spring and thereby disengage or restore the drive connection between the rotating cover and the winding reel.

[0008] Furthermore, a one-way braking member is installed between the rotating lid and the winding base to drive the winding reel so that the rotating lid rotates in one direction along the winding direction and locks the direction.

[0009] Furthermore, the fixed base includes a connecting piece, and a mounting groove is provided on the upper surface of the connecting piece. The winding base is installed in the mounting groove, and a string winding space is formed between the mounting groove and the winding cavity. A central column is installed in the center of the mounting groove, and the central column passes through the string winding central hole of the winding reel and the transmission central hole of the transmission wheel in sequence, with its upper end corresponding to the fitting central hole of the button. The return spring is fitted onto the central column and is located between the winding reel and the transmission wheel.

[0010] Specifically, the winding reel is installed in the string storage chamber via a rotating ring portion, a winding column is installed below the rotating ring portion, the winding column is rotatably fitted onto the central column via a winding central hole, the rotating ring portion and the winding rotation limiting block in the string storage chamber work together to form a string winding space between the mounting groove, the rotating ring portion and the winding column.

[0011] Furthermore, the one-way braking member includes a plurality of claw arms, each claw arm having a claw portion at one end and a braking connection base at the other end, and the braking connection bases are sequentially attached to the braking connection holes at the upper edge of the winding base, so that the claw portions are distributed along the winding direction and engage with each other with the one-way claw wheel portion on the inner wall of the rotating cover. This structure ensures a stable fitting assembly during use, forms a restrictive engagement to prevent rotation, and facilitates winding of the cord.

[0012] Furthermore, the transmission wheel is fitted onto the central column via the transmission center hole, a first drive tooth portion is installed on the upper part of the transmission wheel, and a second drive tooth portion is installed around the pressing hole on the rotating cover corresponding to the first drive tooth portion, and the return spring presses against the first drive tooth portion and the second drive tooth portion to engage.

[0013] Specifically, the first drive tooth portion includes a horizontal clutch tooth surface inclined around the central column, the lower part of the horizontal clutch tooth surface is a limiting clutch tooth base, the second drive tooth portion is provided with clutch teeth that engage with each other corresponding to the horizontal clutch tooth surface, a plurality of pressure limiting grooves are uniformly provided on the side wall of the pressing hole, the limiting clutch tooth base and the pressure limiting grooves are uniformly fitted radially around the central column, a transitional inclined surface is provided between the clutch tooth portion and the pressure limiting groove, a sawtooth portion is provided at the lower end of the button corresponding to the horizontal clutch tooth surface, the top of the sawtooth portion acts on the surface of the horizontal clutch tooth surface, causing the drive wheel to rotate around the central column together with the teeth of the sawtooth portion, and the drive wheel switches between a meshing state between the clutch tooth portion and the horizontal clutch tooth surface and a fitted state between the limiting clutch tooth base and the pressure limiting groove.

[0014] Specifically, the first drive tooth portion is an axially distributed triangular tooth portion, and the second drive tooth portion is a radially distributed triangular gear portion. The axial triangular tooth portion is pressed and fitted into the radially distributed triangular gear portion by the return spring, and the button acts on the transmission wheel to switch between separating and returning the axial triangular tooth portion and the radially distributed triangular gear portion.

[0015] Optionally, a first axial guide tapered tooth portion is installed at the upper end of the axial triangular tooth portion, and a second axial guide tapered tooth portion is installed at the lower part of the radial triangular gear portion, and the first axial guide tapered tooth portion and the second axial guide tapered tooth portion are guided in the axial direction by the action of the return spring, so that the axial triangular tooth portion and the radial triangular gear portion mesh with each other.

[0016] Furthermore, a second transmission tooth section is installed at the lower part of the transmission wheel, and a first transmission tooth section is installed correspondingly at the upper part of the winding reel, or a plurality of transmission pin holes are installed at the lower part of the transmission wheel, and a plurality of transmission pins are installed correspondingly at the upper part of the winding reel. With the above structure, it is easy to use as it is elastically pushed up during use, and cooperative rotation is formed in accordance with the meshing structure.

[0017] Furthermore, multiple pressure-restricting grooves are uniformly installed on the side wall of the pressure hole, and a restriction block is installed on the outer circumferential wall of the button corresponding to the pressure-restricting grooves. The restriction block restricts the pressure on the pressure hole so that the button does not come off.

[0018] Compared to conventional technology, the beneficial effects of this disclosure are as follows:

[0019] The press-and-rotate cord fastener provided in the embodiments of this disclosure incorporates a return spring, a drive wheel, a rotating cover, and a button. The rotating cover is driven by the drive wheel to rotate the winding reel within the winding base. When the button is pressed, it acts on the drive wheel, compressing the return spring, thereby separating or restoring the drive connection between the rotating cover and the winding reel. This allows the winding lock state of the cord fastener to be switched on or off using only the button. Consequently, the button can be pressed in cooperation with both feet or other ground objects, freeing both hands and eliminating the need to bend at the waist, thereby improving the user experience.

[0020] Furthermore, by installing a unidirectional braking member with an elastic structure, the rotating lid must perform unidirectional rotation with a constant force, preventing free return rotation. The structure is simple and the locked state is stable, achieved through methods such as pawl meshing, tooth meshing, and pin fitting. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0022] The technical solutions in the embodiments of this disclosure are described below clearly and completely with reference to the accompanying drawings of the embodiments of this disclosure. Obviously, the embodiments described are only a selection of the embodiments of this disclosure, not all of them. All other embodiments that can be obtained by those skilled in the art without creative work based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0023] (Example 1) As shown in Figures 1 to 5, the press-rotate type lace fastener according to an embodiment of the present disclosure includes a fixed base 10 installed on the upper, tongue, heel, clothing and hat, or bag, the fixed base 10 having a winding base 20 installed on it, a lace storage chamber 21 in the winding base 20 having a winding reel 30 installed in it, the winding reel 30 having a return spring 40, a drive wheel 50 and a rotating cover 60 installed on it in sequence, the rotating cover 60 drives the winding reel 30 to rotate within the winding base 20 by the drive wheel 50, the rotating cover 60 has a button 70 installed on it, and when the button 70 is pressed it acts on the drive wheel 50 and compresses the return spring 40, thereby separating or returning the drive connection between the rotating cover 70 and the winding reel 30.

[0024] As shown in Figures 3 to 5, a one-way braking member 80 is installed between the rotating cover 70 and the winding base 20, which drives the winding reel 30 to rotate in one direction along the winding direction and locks the direction.

[0025] As shown in Figures 4 and 5, the fixed base 10 includes a connecting piece 11, and a mounting groove 12 is provided on the upper surface of the connecting piece 11. The winding base 20 is installed in the mounting groove 12, forming a winding space between the mounting groove 12 and the winding chamber 21. Specifically, the bottom of the winding base 20 engages with the locking holes 16 and positioning holes 17 in the mounting groove 12 by a plurality of locking parts 25 and a plurality of positioning guide columns 26.

[0026] Optionally, the connecting piece 11 can be attached to the upper, tongue, heel, clothing and hat, or bag via fixing holes 18 at the edge, or the connecting piece 11 can be fixed by means of adhesive or other means.

[0027] As shown in Figures 3 to 5, a central column 13 is installed in the center of the mounting groove 12, and the central column 13 passes through the winding central hole 33 of the winding reel 30 and the transmission central hole 51 of the transmission wheel 50 in sequence, with its upper end corresponding to the fitting central hole 71 of the button 70, and the return spring 40 is fitted onto the central column 13 between the winding reel 30 and the transmission wheel 50.

[0028] Specifically, the winding reel 30 is installed in the string storage chamber 21 via a rotating ring portion 31, a winding column 32 is installed below the rotating ring portion 31, and the winding column 32 is rotatably fitted onto the central column 13 via a winding central hole 33. The rotating ring portion 31 and the winding rotation limiting block 33 in the string storage chamber 21 work together to form a string winding space between the mounting groove 12, the rotating ring portion 31, and the winding column 32. Compared to conventional winding reels that use an "I" shaped structure to form a bobbin, when a bobbin is formed using a mounting groove, the rotating ring portion of the winding reel, and a winding column, the thickness dimension of the press-rotate string stopper can be reduced, making it possible to make it thinner.

[0029] Specifically, a first string hole 23 and a second string hole 24 are provided on the radially positioned side of the winding base 20 within the string storage chamber 21, and a first string groove 14 and a second string groove 15 are provided on the fixing base 10 corresponding to the first string hole 23 and the second string hole 24. At the same time, a first string threading hole 34 and a second string threading hole 35 are provided within the winding column 32 so as to surround the winding center hole 33, and the first string threading hole 34 and the second string threading hole 35 correspond to the first string hole 23 and the second string hole 24.

[0030] Selectively, a string-feeding hole 27 is provided at the entrances of the first string hole section 23, the first string-threading hole 34, and the second string-threading hole 35 of the second string hole section 24, and at the exits of the winding base 20 corresponding to the first string-threading hole 23 and the second string-threading hole 24.

[0031] As shown in Figures 4 and 5, the one-way braking member 80 includes a plurality of claw arms 81, with a claw portion 82 installed at one end of each claw arm 81 and a braking connecting base 83 installed at the other end. The braking connecting base 83 is sequentially installed in the braking connecting holes 28 on the upper edge of the winding base 20, so that the claw portions 82 are distributed along the winding direction and engage with the one-way claw wheel portion 65 on the inner wall of the rotating cover 60. This structure ensures a stable fitting assembly during use, forms a restrictive engagement to prevent rotation, and facilitates winding of the cord.

[0032] As shown in Figures 3 to 5, the transmission wheel 50 is fitted onto the central column 13 via the transmission center hole 51, a first drive tooth portion 53 is installed on the upper part of the transmission wheel 50, and a second drive tooth portion 62 is installed on the rotating cover 60 around the pressing hole 61 corresponding to the first drive tooth portion 53. The return spring 40 presses the first drive tooth portion 53 and the second drive tooth portion 62 to engage. As shown in Figures 3 to 5, a second transmission tooth portion 52a is installed on the lower part of the transmission wheel 50, and a first transmission tooth portion 36a is installed on the upper part of the winding reel 30 accordingly. With the above structure, it is elastically pushed up during use for ease of use and works in cooperation with the meshing structure to form an interlocking rotation setting.

[0033] Specifically, a plurality of pressure limiting grooves 63 are uniformly installed on the side wall of the pressure hole 61, and a limiting block 72 is installed on the outer circumferential wall of the button 70 corresponding to the pressure limiting grooves 63. The limiting block 72 restricts the button 70 to the pressure hole 61 so that it does not come off. Selectively, a through-pressure guide groove 64 is further installed on the side wall of the pressure hole 61, and a guide block 73 is installed on the outer circumferential wall of the button 70 corresponding to the pressure guide groove 64.

[0034] Specifically, the one-way ratchet portion 65 is installed around the second drive tooth portion 62, and a rotating cover locking ring member 66 is installed at the lower end of the rotating cover 60. The rotating cover locking ring member 66 corresponds to the locking ring fitting portion 210 on the outer peripheral wall of the winding base 20. In this embodiment, the press-type rotary cord stopper is configured such that a return spring, a transmission wheel, a rotating cover, and a button are installed, and the return spring, transmission wheel, rotating cover, and button form a structure similar to a press-type ballpoint pen. The button acts on the transmission wheel, converting linear motion into rotational motion of the transmission wheel, thereby changing the engagement state between the rotating cover and the transmission wheel, and causing the first transmission tooth portion and the second transmission tooth portion between the transmission wheel and the winding reel to mesh with each other. Thus, the winding lock state of the cord stopper can be switched using only the button. The specific operating principle of the return spring, transmission wheel, rotating cover, and button will be explained in Embodiment 2.

[0035] (Example 2) As shown in Figures 6 to 10, compared to Example 1, the other press-rotate cord fastener provided in Example 2 has a different shape of the rotating lid 60, eliminating the screw structure of the rotating lid in Example 1 and adopting a polyhedral structure to achieve an anti-slip function.

[0036] Furthermore, as shown in Figures 9 and 10, the one-way braking member 80 further includes a braking connecting ring 84, and each of the braking connecting bases 83 is fixed to the braking connecting ring 84. The braking connecting ring 84 engages with the braking support base 29 in the winding base 20. Installing the one-way braking member 80 integrally is advantageous for production assembly.

[0037] Next, in Embodiment 2, the guide block was eliminated in the button, and the corresponding pressure guide groove was eliminated in the rotating cover 60. By positioning the limiting block 72 at the protruding position at the bottom of the button 70, it is made to better match the pressure limiting groove 63 of the button 70, eliminating the need for a through-pressure guide groove in the button, allowing the limiting block to be hidden, making the button thinner, allowing the limiting to be lower, and making the overall design thinner.

[0038] As shown in Figures 9 to 11, the first drive tooth portion 53 includes a horizontal clutch tooth surface 53a inclined around the central column, the lower part of the horizontal clutch tooth surface 53a is a limiting clutch tooth base 53b, and corresponding to the horizontal clutch tooth surface 53a, the second drive tooth portion 62a is provided with a clutch tooth portion 62a that fits with it. Multiple pressure limiting grooves 63 are uniformly provided on the side wall of the pressing hole 61, and the limiting clutch tooth base 62a and the pressure limiting grooves 63 fit uniformly in the radial direction around the central column 13. A transitional inclined surface 62b is provided between the clutch tooth portion 62a and the pressure limiting grooves 63. Corresponding to the horizontal clutch tooth surface 53a, a sawtooth portion 74 is installed at the lower end of the button 70, and as the top of the sawtooth portion 74 acts on the surface of the horizontal clutch tooth surface 53a, the transmission wheel 50 rotates around the central column 13 together with the teeth of the sawtooth portion 74, and the transmission wheel 50 switches between a state in which the clutch tooth portion 62a and the horizontal clutch tooth surface 53a are engaged and a state in which the limiting clutch tooth base portion 53b and the pressing limiting groove 63 are engaged.

[0039] As shown in Figures 12 and 15, the press-type rotating cord fastener is in its initial state, in which case the return spring 40 is in an extended state, and the return spring 40 presses the transmission wheel 50, causing the first drive teeth 53 on the transmission wheel 50 to engage with the second drive teeth 62 on the rotating cover 60, specifically the horizontal clutch tooth surface 53a and the clutch teeth 62a to engage with each other, and the lower second transmission teeth 52a on the transmission wheel 50 to engage with the first transmission teeth 36a on the winding reel 30. In this case, the rotating cover 60 is rotated along the limiting direction of the ratchet wheel, and the transmission wheel 50 acts on the winding reel 50 so that the winding reel 50 is rotated within the winding base 20, thereby winding the cord from the first cord hole 23 and the second cord hole 24 of the winding base 20 onto the winding column 32 of the winding reel 30, performing winding and effectively tightening the gloves, shoes, etc. used.

[0040] As shown in Figures 13 and 16, after the first press of the button 70, it is restricted by the limiting block 72 and the pressing limiting groove 63 of the rotating cover 60, and moves downward along the axial direction of the central column 13 within the pressing hole 61, acting on the drive wheel 50 and compressing the return spring 40. The sawtooth portion 74 at the lower end of the button 70, with its top acting on the surface of the horizontal clutch tooth surface 53a of the first drive tooth portion 53, moves the drive wheel 50 downward along the axial direction, and rotates around the central column 13 together with the teeth of the sawtooth portion 74 until the first drive tooth portion 36a and the second drive tooth portion 52a reach their meshing limit.

[0041] As shown in Figures 14 and 17, after the button 70 is released, the return spring 40 biases the drive wheel 50 to return to its original upward axial position. Since the drive wheel 50 rotated when the button 70 was pressed for the first time, the first drive teeth 53 on the drive wheel 50 are not engaged with the second drive teeth 62 on the rotating cover 60 after it has returned to its original position. Specifically, the horizontal clutch tooth surface 53a interacts with the transition inclined surface 62b, and due to the action of the return spring 40, the horizontal clutch tooth surface 53a of the first drive tooth surface 53 slides upward along the transition inclined surface 62b.

[0042] As shown in Figures 15 and 18, under the action of the return spring 40, the horizontal clutch tooth surface 53a of the first drive tooth portion 53 slides upward along the transition inclined surface 62b, causing the transmission wheel 50 to rotate and move upward, so that the limiting clutch tooth base 53b of the first drive tooth portion 53 enters the pressing limiting groove 63, and both the limiting clutch tooth base 53b and the limiting block 72 of the button 70 are positioned within the pressing limiting groove 63. At this time, the transmission wheel 50 presses the return spring 40 to the highest point of the central column 13, so that the first transmission tooth portion 36a and the second transmission tooth portion 52a separate from each other, that is, the winding reel 30 can be disengaged, and it can be unfolded and used in gloves, shoes, etc., and the user's hands can be freed when using it. For example, when applied to shoes, if a user wants to take off their shoes, they can simply press the button on the right shoelace fastener with their left foot, allowing them to remove the shoe from the right foot first, effectively freeing both hands and eliminating the need to bend over. Furthermore, it resolves the industry's inherent conflict between product pull-out strength and product durability, improving stability during use.

[0043] As shown in Figures 16 and 19, when the button 70 is pressed again, the transmission wheel 50 moves downward in the axial direction, causing the limiting clutch tooth root 53b of the first drive tooth 53 to separate from the pressure limiting groove 63, and the top of the sawtooth portion 74 to act again on the surface of the horizontal clutch tooth surface 53a of the first drive tooth 53. As a result, the transmission wheel 50 moves downward in the axial direction, and the first transmission tooth 36a and the second transmission tooth 52a rotate together with the sawtooth portion 74 around the central column 13 until they reach the engagement limit release button 70 again. After the button 70 is released, the return spring 40 moves to push the transmission wheel 50 upward in the axial direction to return it to its original position. When the button 70 is pressed for the second time, the transmission wheel 50 has rotated, so the limiting clutch tooth root 53b of the first drive tooth 53 on the transmission wheel 50 after it has returned no longer corresponds to the pressure limiting groove 63. Specifically, the horizontal clutch tooth surface 53a interacts with the clutch tooth 62a, and due to the action of the return spring 40, the horizontal clutch tooth surface 53a of the first drive tooth 53 slides upward at an angle along the clutch tooth portion 62a until it engages with the clutch tooth, and at this time the press-rotate type cord stopper is maintained in its initial state.

[0044] (Example 3) As shown in Figures 20 to 25, compared to Examples 1 and 2, in Example 3, multiple transmission pin holes 52b are installed at the bottom of the transmission wheel 50 of the press-rotate cord fastener, and correspondingly, a large number of transmission pins 36b are installed at the top of the winding reel 30. The transmission pin holes 52b engage with the transmission pins 36b.

[0045] As shown in Figures 23 to 25, the first drive tooth portion 53 is an axially distributed triangular tooth portion 53c, and the second drive tooth portion 62 is an axially distributed triangular gear portion 62c. The axial triangular tooth portion 53c is pressed and fitted into the radially distributed triangular gear portion 62c by the return spring 40, and the button 70 acts on the transmission wheel 50 to switch between the separation and return of the axial triangular tooth portion 53c and the radially distributed triangular gear portion 62c. Selectively, a first axial guide tapered tooth portion 53d is installed at the upper end of the axial triangular tooth portion 53c, and a second axial guide tapered tooth portion 62d is installed at the lower part of the radially distributed triangular gear portion 62c. The first axial guide tapered tooth portion 53d and the second axial guide tapered tooth portion 62d are guided axially by the action of the return spring 40, causing the axial triangular tooth portion 53c and the radial triangular gear portion 62c to mesh with each other. The first axial guide tapered tooth portion 53d and the second axial guide tapered tooth portion 62d can achieve rapid corresponding engagement of the axial triangular tooth portion 53c and the radial triangular gear portion 62c by the action of the return spring 40.

[0046] When in use, the press-type rotary cord fastener is in its initial state, and at this time the return spring is extended, which presses against the drive wheel, causing the drive pin hole at the bottom of the drive wheel and the drive pin installed at the top of the winding reel to engage with each other, and the first drive tooth portion and the second drive tooth portion to mesh with each other. Specifically, the axial triangular tooth portion is pressed against and engages with the radial triangular gear portion by the return spring. At this time, the rotating cover rotates along the limiting direction of the ratchet wheel, and the winding reel rotates within the winding base due to the action of the drive wheel, winding the cord from the first cord hole portion and the second cord hole portion of the winding base onto the winding column of the winding reel, winding the cord and effectively tightening the gloves, shoes, etc. being used.

[0047] Next, after pressing the button, the button moves downward along the axial direction of the central column within the pressing hole, under the restriction of the pressing restriction groove of the rotating cover by the limiting block, acting on the transmission wheel, compressing the return spring, and separating the first and second drive teeth from each other, thereby releasing the winding reel from the engagement restriction. It can be deployed and used in gloves, shoes, etc., and frees the user's hands when in use. For example, when applied to shoes, if a user wants to take off their shoes, they can simply press the button on the right shoelace fastener with their left foot, and the shoe will come off from the right foot, effectively freeing both hands and eliminating the need to bend over. After the button is released, the return spring biases the transmission wheel to return to its original upward axial direction. The axial triangular teeth are pressed and engaged with the radial triangular gear by the return spring, and at this time the press-rotating lace fastener is in its initial state.

[0048] The press-and-rotate cord fastener provided in the embodiments of this disclosure incorporates a return spring, a drive wheel, a rotating cover, and a button. The rotating cover is driven by the drive wheel to rotate the winding reel within the winding base. When the button is pressed, it acts on the drive wheel, compressing the return spring, thereby separating or restoring the drive connection between the rotating cover and the winding reel. This allows the winding lock state of the cord fastener to be switched on or off using only the button. Consequently, the button can be pressed in cooperation with both feet or other ground objects, freeing both hands and eliminating the need to bend at the waist, thereby improving the user experience.

[0049] Furthermore, by installing a unidirectional braking member with an elastic structure, the rotating lid must perform unidirectional rotation with a constant force, preventing free return rotation. The structure is simple and the locked state is stable, achieved through methods such as pawl meshing, tooth meshing, and pin fitting.

[0050] Anything not described in detail herein is the prior art well known to those skilled in the art.

[0051] Although embodiments of this disclosure have been described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this disclosure.
