Description

Push-and-turn lace-up buckle Technical Field

[0001] The utility model relates to the technical field of lace buckles, in particular to a push-to-rotate lace buckle. Background Art

[0002] Lace buckles are mainly used to tighten or loosen straps on shoes, clothing, backpacks, and rehabilitation equipment. Lace buckles are being widely used. This type of product provides a portable experience for the majority of users, but there are still some problems with the existing manual tensioning buttons when using them.

[0003] For example, Chinese invention patent publication number CN108791997A provides a lacing device comprising a rotor and a stator, the stator comprising a sleeve, the rotor comprising an upper cover and a winding groove arranged sequentially from top to bottom, the sleeve being provided with a pawl, and the upper cover correspondingly provided with teeth; both the rotor and the stator being provided with a gear structure, the pawl and the teeth being engaged or disengaged by the gear structure; due to the gear structure, when the upper cover is pressed, the upper cover engages with the winding groove, and the teeth of the upper cover engage with the pawls of the sleeve, at which point the lacing system is in a first gear state; when the rotor is rotated forward, the lacing is wound around the winding groove in a tightening direction; in this gear state, the rotor cannot be reversed, thereby achieving the function of tightening the lacing. When the upper cover is pulled up, the pawl disengages from the teeth, the rotor is no longer subject to a one-way constraint, and the rotor upper cover is disconnected from the winding groove. At this time, the upper cover and the winding groove can rotate freely forward and backward, thereby achieving the function of automatically loosening the lacing. For example, announcement number: CN218635442U provides a lace buckle. When loosening the shoelaces, the cover body is first pulled upward and then rotated to loosen the shoelaces. After the cover body is pressed, the ratchet piece engages with the one-way teeth. When the user rotates the cover body, the cover body can only rotate in one direction, so that the shoelaces are wound around the surface of the winding disk, tightening the shoelaces.

[0004] The above-mentioned lace buckle usually adopts a radially movable cover to switch the lace buckle between loosening and tightening the belt, which means that the user needs to bend down and operate manually whether loosening or tightening the belt. In addition, due to the use of a clutch structure, the structure is usually more complicated, and repeated pulling and pulling can easily cause damage. Utility Model Content

[0054] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0055] As shown in Figures 1-5, an embodiment of the present invention provides a press-and-rotate lace buckle, including a fixed base 10 arranged on a shoe upper, a shoe tongue, a shoe heel, a coat or a bag, a winding seat 20 is provided on the fixed base 10, and a winding wheel 30 is provided in a winding cavity 21 in the winding seat 20; a reset spring 40, a transmission wheel 50 and a rotary cover 60 are sequentially provided on the winding wheel 30, and the rotary cover 60 drives the winding wheel 30 to rotate in the winding seat 20 through the transmission wheel 50, and a button 70 is provided on the rotary cover 60. When the button 70 is pressed, it acts on the transmission wheel 50 and compresses the reset spring 40, so that the drive connection state between the rotary cover 70 and the winding wheel 30 is separated and reset.

[0056] As shown in FIG3-5 , a one-way brake 80 is provided between the rotary cover 70 and the winding seat 20 . The one-way brake 80 enables the rotary cover 70 to drive the winding wheel 30 to rotate unidirectionally along the winding direction and lock the direction.

[0057] 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 seat 20 is disposed in the mounting groove 12, and a cord winding space is formed between the mounting groove 12 and the cord winding cavity 21. Specifically, the bottom of the winding seat 20 cooperates with the locking hole 16 and positioning hole 17 in the mounting groove 12 via a plurality of snap portions 25 and a plurality of positioning guide posts 26.

[0058] Optionally, the connecting piece 11 is mounted on a shoe upper, a shoe tongue, a shoe heel, a garment or a bag through the fixing holes 18 at the edge, or the connecting piece 11 is fixed by bonding or other methods.

[0059] As shown in Figures 3-5, a center column 13 is provided in the middle of the mounting groove 12. The center column 13 passes through the winding center hole 33 of the winding wheel 30 and the transmission center hole 51 of the transmission wheel 50 in sequence and corresponds to the matching center hole 71 of the button 70 at the upper end. The reset spring 40 is sleeved on the center column 13 and is located between the winding wheel 30 and the transmission wheel 50.

[0060] Specifically, the winding wheel 30 is disposed within the wire-receiving cavity 21 via a rotating ring portion 31. A winding post 32 is disposed below the rotating ring portion 31. The winding post 32 is rotatably sleeved on the center post 13 via a winding center hole 33. The rotating ring portion 31 cooperates with a winding rotation limit block 33 within the wire-receiving cavity 21 to form a wire-receiving space between the mounting groove 12, the rotating ring portion 31, and the winding post 32. Compared to existing winding wheels that use an I-shaped structure as a wire bin, the use of a mounting groove, the rotating ring portion of the winding wheel, and the winding post to form a wire bin can reduce the thickness of the push-to-turn lace buckle, making it thinner.

[0061] Specifically, the wire take-up cavity 21 is provided with a first wire hole portion 23 and a second wire hole portion 24 on the radial side of the winding seat 20, and a first wire groove 14 and a second wire groove 15 are provided on the fixed base 10 corresponding to the first wire hole portion 23 and the second wire hole portion 24. At the same time, a first wire threading hole 34 and a second wire threading hole 35 are provided in the winding post 32 around the winding center hole 33, and the first wire threading hole 34 and the second wire threading hole 35 correspond to the first wire hole portion 23 and the second wire hole portion 24.

[0062] Optionally, the first wire hole portion 23 and the second wire hole portion 24 correspond to the entrances of the first wire hole 34 and the second wire hole 35 , and the winding seat 20 is provided with a wire outlet hole 27 corresponding to the outlets of the first wire hole 23 and the second wire hole 24 .

[0063] As shown in Figures 4 and 5, the one-way brake member 80 includes a plurality of ratchet arms 81, each of which has a ratchet portion 82 at one end and a brake connection seat 83 at the other end. The ratchet arms 81 are sequentially mounted within the brake connection holes 28 on the upper edge of the winding seat 20 via the brake connection seats 83. The ratchet portions 81 are distributed along the winding direction and engage with the one-way ratchet portion 65 on the inner wall of the rotary cover 60. This structure allows for stable nested assembly during use, forms a limited engagement, prevents rotation, and facilitates winding of the cord.

[0064] As shown in Figures 3-5 , the transmission wheel 50 is sleeved onto the center column 13 through the transmission center hole 51. A first drive tooth portion 53 is provided on the upper portion of the transmission wheel 50. Corresponding to the first drive tooth portion 53, a second drive tooth portion 62 is provided on the rotary cover 60, surrounding the pressing hole 61. The return spring 40 forces the first drive tooth portion 53 and the second drive tooth portion 62 into a tight engagement. As shown in Figures 3-5 , a second drive tooth portion 52a is provided on the lower portion of the transmission wheel 50, corresponding to the first drive tooth portion 36a provided on the upper portion of the winding wheel 30. This structure facilitates elastic lifting during use and, in conjunction with the meshing structure, forms a linked rotation arrangement.

[0065] Specifically, the sidewall of the press hole 61 is evenly provided with a plurality of press-limiting grooves 63, and corresponding press-limiting blocks 72 are provided on the outer peripheral wall of the button 70. The limit blocks 72 restrain the button 70 in the press hole 61 and prevent it from falling out. Optionally, the sidewall of the press hole 61 is further provided with a continuous press guide groove 64, and corresponding press guide grooves 64 are provided on the outer peripheral wall of the button 70.

[0066] Specifically, the one-way ratchet portion 65 is arranged around the second drive tooth portion 62, and a rotary cover snap ring 66 is provided at the lower end of the rotary cover 60. The rotary cover snap ring 66 corresponds to the snap ring mating portion 210 on the outer peripheral wall of the winding seat 20. The push-to-rotate lace buckle of this embodiment is provided with a reset spring, a transmission wheel, a rotary cover, and a button. The reset spring, transmission wheel, rotary cover, and button form a structure similar to a push-type ballpoint pen. The button acts on the transmission wheel, converting linear motion into rotation of the transmission wheel, thereby changing the mating state between the rotary cover and the transmission wheel, thereby causing the first transmission tooth portion and the second transmission tooth portion between the transmission wheel and the winding wheel to engage and disengage with each other. Therefore, the winding and locking state of the lace buckle can be switched simply by pressing the button. The specific working principles of the reset spring, transmission wheel, rotary cover, and button are described in Example 2. Example 2

[0067] As shown in Figures 6-10, compared with Example 1, Example 2 provides another push-to-rotate lace buckle, in which the shape of the rotary cover 60 is different. The screw thread structure of the rotary cover in Example 1 is eliminated, and a polyhedron structure is used to achieve the anti-slip function.

[0068] 9 and 10 , the one-way brake member 80 further includes a brake connecting ring 84. Each of the brake connecting seats 83 is fixed to the brake connecting ring 84. The brake connecting ring 84 cooperates with the brake receiving platform 29 in the winding seat 20. The one-way brake member 80 is integrated, which is more convenient for production and assembly.

[0069] Secondly, the button of Example 2 eliminates the guide block and the corresponding press guide groove on the rotary cover 60. The limit block 72 is set at the protruding position at the bottom of the button 70, so that it is more consistent with the press limit groove 63 of the button 70, so that the button does not need to have a through press guide groove. The limit block can be hidden and the button can be thinner, so that the limit is lower and the overall body is thinner.

[0070] As shown in Figures 9-11, the first driving tooth portion 53 includes a horizontal clutch tooth surface 53a inclined around the central column 13, and the lower part of the horizontal clutch tooth surface 53a is a limiting clutch tooth root portion 53b. Corresponding to the horizontal clutch tooth surface 53a, a clutch tooth portion 62a that cooperates with each other is provided on the second driving tooth portion 62; a plurality of pressing limiting grooves 63 are evenly provided on the side wall of the pressing hole 61, and the limiting clutch tooth root portion 53b and the pressing limiting groove 63 are evenly matched with each other radially around the central column 13; the clutch tooth portion 62 A transition inclined surface 62b is provided between a and the press limit groove 63; a serrated portion 74 is provided at the lower end of the button 70 corresponding to the horizontal clutch tooth surface 53a, and the top of the serrated portion 74 acts on the surface of the horizontal clutch tooth surface 53a so that the transmission wheel 50 rotates around the center column 13 along with the teeth of the serrated portion 74, and the rotating wheel 50 switches between the meshing state of the clutch tooth portion 62a and the horizontal clutch tooth surface 53a and the cooperation state of the limiting clutch tooth root portion 53b and the press limit groove 63.

[0071] As shown in Figures 12 and 15, the push-to-rotate lace buckle is in an initial state, at which time the return spring 40 is in an extended state, the return spring 40 squeezes the transmission wheel 50, and the first drive tooth portion 53 on the transmission wheel 50 is engaged with the second drive tooth portion 62 of the rotary cover 60. Specifically, the horizontal clutch tooth surface 53a is engaged with the clutch tooth portion 62a, and the second transmission tooth portion 52a on the lower side of the transmission wheel 50 is engaged with the first transmission tooth portion 36a of the winding wheel 30; at this time, the rotary cover 60 is rotated along the direction specified by the ratchet, and the winding wheel 50 is rotated in the winding seat 20 through the action of the transmission wheel 50, and the rope is wound from the first wire hole portion 23 and the second wire hole portion 24 of the winding seat 20 into the winding post 32 of the winding wheel 30 and wound, thereby effectively tightening the gloves, shoes, etc. used.

[0072] As shown in Figures 13 and 16, after the button 70 is pressed for the first time, the button 70 is restricted by the pressing limit groove 63 of the rotary cover 60 through the limit block 72, and moves axially downward along the center column 13 in the pressing hole 61, acting on the transmission wheel 50 and compressing the reset spring 40. The serrated portion 74 at the lower end of the button 70, and the top of the serrated portion 74 acts on the surface of the horizontal clutch tooth surface 53a of the first drive tooth portion 53, so that the transmission wheel 50 moves axially downward and rotates around the center column 13 along the teeth of the serrated portion 74 until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the engagement limit.

[0073] As shown in Figures 14 and 17, after the button 70 is released, the reset spring 40 pushes the transmission wheel 50 to reset axially upward. Since the transmission wheel 50 rotates when the button 70 is pressed for the first time, the first drive tooth portion 53 on the transmission wheel 50 after the reset is no longer engaged with the second drive tooth portion 62 on the rotary cover 60. Specifically, the horizontal clutch tooth surface 53a interacts with the transition inclined surface 62b. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first drive tooth portion 53 will slide obliquely upward along the transition inclined surface 62b.

[0074] 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 will slide obliquely upward along the transition inclined surface 62b, causing the transmission wheel 50 to rotate and move upward, so that the limiting clutch tooth root portion 53b of the first drive tooth portion 53 enters the pressing limit groove 63, so that the limiting clutch tooth root portion 53b and the limiting block 72 of the button 70 are both in the pressing limit groove 63. At this time, the transmission wheel 50 is squeezed at the highest point of the center column 13 by the return spring 40, so that the first transmission tooth portion 36a and the second transmission tooth portion 52a are separated from each other, and the winding wheel 30 can be released from the engagement limit, which can be used for unfolding gloves, shoes, etc. and freeing the user's hands when using them. For example, if used on shoes, if the user wants to take off the shoes, he only needs to press the button of the right foot buckle with his left foot to take off the right shoe, effectively freeing his hands without having to bend over, and solving the contradiction between the pulling force and product firmness of current industry products, thereby improving the stability of use.

[0075] As shown in Figures 16 and 19, when the button 70 is pressed again, as the transmission wheel 50 moves axially downward, the limiting clutch tooth root 53b of the first drive tooth portion 53 leaves the pressing limit groove 63, and the top of the serration 74 acts on the surface of the horizontal clutch tooth surface 53a of the first drive tooth portion 53 again, causing the transmission wheel 50 to move axially downward while rotating around the center column 13 along with the teeth of the serration 74 until the first transmission tooth portion 36a and the second transmission tooth portion 52a reach the meshing limit again; after releasing the button 70, the reset spring 4 0 pushes the transmission wheel 50 to reset axially upward. Since the transmission wheel 50 rotates when the button 70 is pressed for the second time, the limiting clutch tooth root 53b of the first driving tooth portion 53 on the transmission wheel 50 after reset no longer corresponds to the pressing limiting groove 63. Specifically, the horizontal clutch tooth surface 53a interacts with the clutch tooth portion 62a. Under the action of the reset spring 40, the horizontal clutch tooth surface 53a of the first driving tooth portion 53 will slide obliquely upward along the clutch tooth portion 62a until they engage with each other. At this time, the pressing and rotating lace buckle is in the initial state again. Example 3

[0076] As shown in Figures 20-25, compared with Examples 1 and 2, the push-to-rotate buckle of Example 3 has a plurality of transmission pin holes 52b disposed on the lower portion of the transmission wheel 50, corresponding to a plurality of transmission pins 36b disposed on the upper portion of the winding wheel 30. The transmission pin holes 52b are engaged with the transmission pins 36b for transmission.

[0077] As shown in Figures 23-25, the first drive tooth portion 53 is a radially distributed axial triangular tooth portion 53c, and the second drive tooth portion 62 is an axially distributed radial triangular gear portion 62c. The axial triangular tooth portion 53c is pressed and fitted with the radial triangular gear portion 62c by the reset spring 40. The drive wheel 50 switches the axial triangular tooth portion 53c and the radial triangular gear portion 62c between separation and reset by the action of the button 70. Optionally, a first axial guide bevel tooth portion 53d is provided at the upper end of the axial triangular tooth portion 53c, and a second axial guide bevel tooth portion 62d is provided at the lower end of the radial triangular gear portion 62c. The first axial guide bevel tooth portion 53d and the second axial guide bevel tooth portion 62d are axially guided by the reset spring 40 so that the axial triangular tooth portion 53c and the radial triangular gear portion 62c engage with each other. Under the action of the return spring 40 , the first axial guide bevel tooth portion 53 d and the second axial guide bevel tooth portion 62 d can achieve rapid corresponding fit between the axial triangular tooth portion 53 c and the radial triangular gear portion 62 c .

[0078] When in use, the press-and-rotate lace buckle is in the initial state, at which time the reset spring is in the extended state, the reset spring squeezes the transmission wheel, the transmission pin hole at the lower part of the transmission wheel cooperates with the transmission pin provided on the upper part of the winding wheel, the first drive tooth portion and the second drive tooth portion are meshed with each other, specifically, the axial triangular tooth portion is pressed and fitted with the radial triangular gear portion through the reset spring; at this time, the rotary cover is rotated along the direction limited by the ratchet, and the winding wheel is rotated in the winding seat through the action of the transmission wheel, and the rope is wound from the first wire hole portion and the second wire hole portion of the winding seat into the winding post of the winding wheel and wound, effectively tightening the gloves, shoes, etc. used.

[0079] Afterwards, after pressing the button, the button is restricted by the pressing limit groove of the rotary cover through the limit block, and moves axially downward along the center column in the pressing hole, acting on the transmission wheel and compressing the reset spring. The first drive tooth portion and the second drive tooth portion are separated from each other, and the winding wheel can be disengaged from the engagement limit, which can be unfolded and used for gloves, shoes, etc., and the user's hands can be freed when in use. For example, if used on shoes, if the user wants to take off the shoes, he only needs to press the button of the right foot buckle with his left foot to take off the right shoe, effectively freeing his hands without having to bend over; after releasing the button, the reset spring pushes the transmission wheel to reset axially upward, and the axial triangular tooth portion is pressed tightly with the radial triangular gear portion through the reset spring. At this time, the pressing and rotating lace buckle is in the initial state again.

[0080] The push-to-rotate lace buckle provided by the embodiment of the present invention is equipped with a reset spring, a transmission wheel, a rotary cover and a button. The rotary cover drives the winding wheel to rotate in the winding seat through the transmission wheel. When the button is pressed, it acts on the transmission wheel and compresses the reset spring, so that the drive connection state between the rotary cover and the winding wheel is separated and reset. Therefore, the winding and locking state of the lace buckle can be switched or released only by pressing the button. The button can even be pressed with both feet or with the help of other ground objects, freeing up hands and bending over to operate, thereby improving user experience.

[0081] In addition, by setting a one-way brake with an elastic structure, the rotary cover needs to be retracted and rotated in one direction under a certain force to prevent free rotation. Through ratchet engagement, tooth engagement, pin matching and other methods, the structure is simple and the locking state is stable.
