Description

Technical Field

[0001] This application relates to the technical field of daily necessities, and particularly relates to a untied rope knob. Background Art

[0002] Shoes are necessities in people's daily lives. Many shoes have shoelaces, and by adjusting the tightness of the shoelaces, the shoes can be put on and taken off.

[0003] In order to tie or loosen the shoelaces, people often squat down and use both hands to tie or loosen them. This is very inconvenient. Moreover, when the shoelaces are tied by hand knotting, it is easy to have problems such as loosening and fading. Also, it takes a long time to tie or loosen the shoelaces, and it cannot be operated with one hand, making it difficult for disabled people or children to operate.

[0004] In view of this, how to conveniently and reliably tighten a rope such as a shoelace is a technical problem that those skilled in the art need to consider. Summary of the Invention

[0005] The purpose of this application is to provide a untied rope knob that can conveniently and reliably tighten a rope such as a shoelace.

[0007] A driving rotary cover;

[0008] A storage turntable, connected to the driving rotary cover. The side wall of the storage turntable is provided with an elastic ratchet. The storage turntable has an extension end in the direction away from the driving rotary cover, and the extension end is used to fix and wind the rope.

[0009] A gear ring, provided with annular ratchet teeth. The gear ring can move in the directions facing and away from the driving rotary cover. When the ratchet teeth move to the outside of the elastic ratchet, the elastic ratchet and the ratchet teeth cooperate, and the elastic ratchet can rotate unidirectionally relative to the ratchet teeth.

[0010] A dial, arranged on the end face of the gear ring away from the driving rotary cover. The end face of the dial facing the gear ring is provided with a top block.

[0011] A base, located below the driving rotary cover and forming a receiving space with the driving rotary cover. The storage turntable, the gear ring, and the dial are located in the receiving space. The base is provided with a through hole for the rope to pass through.

[0012] By rotating the dial, the top block jacks up the gear ring, and the elastic ratchet and the ratchet teeth are in a cooperating or disengaged state. When the elastic ratchet and the ratchet teeth cooperate, rotate the driving rotary cover, and the storage turntable rotates relative to the gear ring to wind the rope by the extension end. When the elastic ratchet and the ratchet teeth are disengaged, the rope is released from the extension end outside the base, and at the same time, the driving rotary cover and the storage turntable are driven to rotate.

[0013] Optionally, an elastic arm is provided on the end surface of the gear ring facing the driving rotary cover, and the elastic arm and the driving rotary cover abut against each other. When the top block lifts the gear ring, the elastic arm is compressed. When the top block does not lift the gear ring, the elastic potential energy of the elastic arm is released to push the ratchet away from the driving rotary cover.

[0014] Optionally, a matching block is further provided on the end surface of the gear ring facing the dial, and when the dial is rotated to a preset angle, the top block contacts the matching block to lift the gear ring.

[0015] Optionally, opposite ends of the top block and the matching block are inclined.

[0016] Optionally, a notch is further provided on the outer edge of the dial, and the notch is used to avoid the matching block.

[0017] Optionally, the dial is provided with a toggle body, the toggle body extends out of the base, the base is provided with a slide groove, the toggle body can slide in the slide groove, and when the toggle body slides to one end of the slide groove, the top block lifts the gear ring.

[0018] Optionally, the outer side wall of the base is further provided with a stop point, and when the toggle body slides to the end of the slide groove, the toggle body is embedded and fixed at the stop point.

[0019] Optionally, a limit strip is further provided on the inner side wall of the base, and a slider is further provided on the end face of the dial away from the driving rotary cover. The slider and the end face of the dial away from the driving rotary cover form a boss structure, which overlaps the limit strip, and the outer side wall of the slider is slidably matched with the limit strip.

[0020] Optionally, a limit block is further provided on the inner side wall of the base, and a limit groove is further provided on the outer edge of the gear ring, wherein the limit block is accommodated in the limit groove to prevent the gear ring from rotating relative to the base.

[0021] Optionally, a locking ring is provided at the bottom of the base, and the storage turntable is also provided with a rope stopper plate, which is provided at the extension end. A locking column is provided at the end of the extension end, and the locking column is used to be rotatably connected to the locking ring. The extension end is provided with a rope winding hole distributed along its axial direction, and the rope winding hole is located between the locking column and the rope stopper plate. The two rope bodies are wound between the locking column and the rope stopper plate through the rope winding hole.

[0022] Compared with the above background art, the untethered knob provided by the present application includes: a driving rotary cover, a storage turntable, a toothed ring, a dial and a base. The driving rotary cover is connected to the storage turntable and can rotate synchronously. The driving rotary cover and the base form an accommodation space, and the storage turntable, the toothed ring and the dial are accommodated in the accommodation space. The extending end of the storage turntable is used for fixing and winding the rope body; an elastic pawl is provided on the side wall of the storage turntable, and an annular ratchet tooth is provided on the toothed ring. The toothed ring can move relative to the storage turntable. When the ratchet tooth moves to the outside of the elastic pawl, the elastic pawl and the ratchet tooth cooperate, and the elastic pawl can rotate unidirectionally relative to the ratchet tooth; the dial is provided with a top block. By rotating the dial, the top block can lift the toothed ring, and the elastic pawl and the ratchet tooth are in a cooperating or disengaged state; when the elastic pawl and the ratchet tooth cooperate, by rotating the driving rotary cover, the storage turntable rotates relative to the toothed ring to wind the rope body at the extending end; when the elastic pawl and the ratchet tooth are disengaged, the rope body is released from the extending end outside the base, and the driving rotary cover and the storage turntable are rotated synchronously.

[0023] For the untethered knob arranged in this way, when it is necessary to tighten the rope body, first rotate the dial to make the elastic pawl and the ratchet tooth cooperate and connect, and then rotate the driving rotary cover, and the rope body can be stored in the accommodation space. When it is necessary to loosen the rope body, rotate the dial to disconnect the elastic pawl and the ratchet tooth. At this time, the rope body in the tensioned state is released from the accommodation space, so that the purpose of loosening the rope body can be achieved. The operation of the above untethered knob is simple and convenient, and it can easily realize the tightening and loosening of, for example, shoelaces; at the same time, the internal layout of the accommodation space is reasonable, and there are no complicated components, so that the space for accommodating the rope body is large. It can not only store more steel shoelaces, but also store ordinary nylon shoelaces with larger volumes, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0065] The tether-free knob provided in the embodiment of the present application is shown in the attached manual. Figure 1 To Attachment Figure 22 The rope-free knob includes: a driving cover 1, a storage turntable 2, a gear ring 3, a dial 4 and a base 5. The base 5 can be regarded as the installation reference of the other components, and can be set to a barrel shape. The base 5 is provided with a receiving cavity, the driving cover 1 is located above the base 5, and the driving cover 1 and the base 5 form a receiving space, and the storage turntable 2, the gear ring 3 and the dial 4 are placed inside the receiving space.

[0066] The driving cover 1 and the receiving turntable 2 can be fixedly connected. In some embodiments, as shown in the attached Figure 3 and attached Figure 4 As shown, a hook 11 is provided on the end surface of the driving rotary cover 1 facing the storage turntable 2, and the storage turntable 2 is provided with a mounting hole 26, in which the hook 11 is embedded, so as to realize a fixed connection between the driving rotary cover 1 and the storage turntable 2.

[0067] Please refer to the attached Figure 5, the side wall of the storage turntable 2 is provided with an elastic pawl 21, and spaces for its deformation are left on both sides of the elastic pawl 21. The storage turntable 2 is provided with an extension end 22 in the direction away from the driving rotary cap 1, and the extension end 22 is used to fix and wind the rope body.

[0068] In some embodiments, the storage turntable 2 is further provided with a rope blocking plate 23. The rope blocking plate 23 is arranged on the extension end 22. A clamping post 24 is arranged at the end of the extension end 22. The extension end 22 is provided with a winding hole 25 distributed along its axial direction. The winding hole 25 is located between the clamping post 24 and the rope blocking plate 23. Two rope bodies are wound between the clamping post 24 and the rope blocking plate 23 through the winding hole 25.

[0069] When winding the rope body on the extension end 22, the rope blocking plate 23 can prevent the rope body from approaching the elastic pawl 21, so as to ensure that the winding operation and the elastic deformation of the elastic pawl 21 do not interfere with each other, thereby improving the use reliability.

[0070] Please refer to the appendix Figure 6 and the appendix Figure 7 , the toothed ring 3 is provided with annular ratchet teeth 31. The toothed ring 3 can move in the directions facing and away from the driving rotary cap 1. When the ratchet teeth 31 move to the outside of the elastic pawl 21, the elastic pawl 21 and the ratchet teeth 31 cooperate, and the elastic pawl 21 can rotate unidirectionally relative to the ratchet teeth 31.

[0071] That is to say, when the toothed ring 3 is moved so that the toothed ring 3 is sleeved on the outer periphery of the elastic pawl 21, then the ratchet teeth 31 of the toothed ring 3 and the elastic pawl 21 can perform unidirectional rotation.

[0072] The inside of the toothed ring 3 is provided with ratchet teeth 31 inclined counterclockwise or clockwise (matched according to whether it is used for left-foot shoes or right-foot shoes). The diameter of the storage turntable 2 matches the inner diameter of the toothed ring 3. When the storage turntable 2 and the toothed ring 3 are assembled and combined, according to the inclination direction of the ratchet teeth 31, a suitable storage turntable 2 is selected. The opening of the elastic pawl 21 of the storage turntable 2 always faces the reverse direction of the ratchet teeth 31. In this way, it can be ensured that when the storage turntable 2 rotates, the elastic pawl 21 undergoes compressive deformation under the extrusion of the ratchet teeth 31. When the storage turntable 2 rotates against the ratchet teeth 31, the elastic pawl 21 will be blocked by the ratchet teeth 31 and cannot rotate reversely. Its principle is similar to that of a ratchet and pawl.

[0073] Please refer to the appendix Figure 8 , the ratchet teeth 31 have a certain inclination angle and are inclined in the clockwise direction. The storage turntable 2 can only rotate in the clockwise direction. At this time, the storage turntable 2 and the toothed ring 3 can be used to fasten the shoelaces of the right shoe. Similarly, please refer to the appendix Figure 9 , the ratchet teeth 31 have a certain inclination angle and are inclined in the counterclockwise direction. The storage turntable 2 can only rotate in the counterclockwise direction. At this time, the storage turntable 2 and the toothed ring 3 can be used to fasten the shoelaces of the left shoe.

[0074] Please refer to the attached Figure 10 and the attached Figure 11 , the dial 4 is provided on the end face of the gear ring 3 facing away from the driving rotary cover 1. A top block 41 is provided on the end face of the dial 4 facing the gear ring 3. By rotating the dial 4, the top block 41 jacks up the gear ring 3, so that the elastic ratchet 21 and the ratchet teeth 31 are in a mating or disengaged state.

[0075] Please also refer to the attached Figure 6 and the attached Figure 7 , a mating block 33 is further provided on the end face of the gear ring 3 facing the dial 4. When the dial 4 is rotated to a preset angle, the top block 41 and the mating block 33 come into contact, so that the gear ring 3 is jacked up, as shown in the attached Figure 12 to the attached Figure 14 shown.

[0076] Looking further, the opposite ends of the top block 41 and the mating block 33 are inclined. That is, the top block 41 and the mating block 33 are in contact with each other, and the top block 41 provides a certain height, so that the gear ring 3 and the dial 4 are in contact. The top block 41 and the mating block 33 have a slope, and the slopes of the top block 41 and the mating block 33 are mirror images of each other. In this way, it can be ensured that the forces on the top block 41 and the mating block 33 are balanced when they are in contact, and the gear ring 3 is jacked up and lowered smoothly, avoiding large impacts on the gear ring 3.

[0077] A notch 44 is further provided on the outer edge of the dial 4. The notch 44 is used to avoid the mating block 33. When the dial 4 is rotated, the top block 41 and the mating block 33 are separated, and the notch 44 can provide space for the gear ring 3 to descend more. When the dial 4 is rotated again, the slopes of the top block 41 and the mating block 33 enable the gear ring 3 to be jacked up smoothly when they come into contact again.

[0078] Please refer to the attached Figure 15 and the attached Figure 16 , the base 5 is provided with a through hole 51 for the rope body to pass through. A clamping ring 57 may be provided at the bottom of the base 5. The clamping column 24 of the storage turntable 2 is rotatably connected to the clamping ring 57, so that the storage turntable 2 can rotate relative to the base 5.

[0079] In addition, a fastening member 12 may be provided at the bottom of the inner side wall of the driving rotary cover 1. A fastening edge 56 is provided on the outer side wall of the base 5. The fastening member 12 and the fastening edge 56 can be rotatably matched, so that the driving rotary cover 1 rotates relative to the base 5. At the same time, under the action of the fastening member 12 and the fastening edge 56, the rotation of the driving rotary cover 1 is stable, ensuring the reliability of use.

[0080] By rotating the dial 4 to make the top block 41 lift the gear ring 3, the elastic pawl 21 and the ratchet tooth 31 are in a mating or disengaged state; when the elastic pawl 21 and the ratchet tooth 31 are mated, rotate the driving cap 1, and the storage turntable 2 rotates relative to the gear ring 3 to make the extension end 22 store the cord; when the elastic pawl 21 and the ratchet tooth 31 are disengaged, the cord is released from the extension end 22 to outside the base 5, and the driving cap 1 and the storage turntable 2 are driven to rotate synchronously.

[0081] Here, there can be two different setting methods. In the first method, when the mating block 33 of the gear ring 3 contacts the top block 41 of the dial 4 and the gear ring 3 is lifted, the ratchet tooth 31 of the gear ring 3 mates with the elastic pawl 21 of the storage turntable 2. At this time, the cord can be tightened by rotating the driving cap 1; correspondingly, when the mating block 33 of the gear ring 3 and the top block 41 of the dial 4 do not contact and the gear ring 3 is not lifted, the ratchet tooth 31 of the gear ring 3 and the elastic pawl 21 of the storage turntable 2 are disengaged, and the cord is relaxed at this time.

[0082] In the second method, when the mating block 33 of the gear ring 3 and the top block 41 of the dial 4 do not contact and the gear ring 3 is lifted, the ratchet tooth 31 of the gear ring 3 mates with the elastic pawl 21 of the storage turntable 2. At this time, the cord can be tightened by rotating the driving cap 1; correspondingly, when the mating block 33 of the gear ring 3 and the top block 41 of the dial 4 contact and the gear ring 3 is not lifted, the ratchet tooth 31 of the gear ring 3 and the elastic pawl 21 of the storage turntable 2 are disengaged, and the cord is relaxed at this time.

[0083] This application is described by taking the first method as an example. As shown in the attached Figure 6 and the attached Figure 7 as shown, an elastic arm 32 is provided on the end face of the gear ring 3 facing the driving cap 1, and the elastic arm 32 abuts against the driving cap 1. When the top block 41 lifts the gear ring 3, the elastic arm 32 is compressed. When the top block 41 does not lift the gear ring 3, the elastic potential energy of the elastic arm 32 is released, pushing the ratchet tooth 31 away from the driving cap 1.

[0084] It can be seen that when the cord needs to be tightened, the mating block 33 and the top block 41 are in contact with each other. At this time, the elastic arm 32 is compressed in the height direction. By rotating the driving cap 1, the elastic pawl 21 of the storage turntable 2 and the ratchet tooth 31 of the gear ring 3 rotate unidirectionally, and the elastic pawl 21 can be fixed in the current position in real time, and the cord remains in a tightened state; when the cord needs to be relaxed, by rotating the dial 4, the mating block 33 and the top block 41 are separated from contact, the elastic potential energy of the elastic arm 32 is released, the gear ring 3 moves away from the driving cap 1, and at this time the storage turntable 2 and the gear ring 3 are separated from contact, and the cord in a taut state is relaxed, driving the storage turntable 2 and the driving cap 1 to rotate in the reverse direction.

[0085] In some embodiments, the dial 4 is provided with a toggle body 42, which extends beyond the base 5. The base 5 is provided with a slide groove 52, in which the toggle body 42 can slide. When the toggle body 42 slides to one end of the slide groove 52, the top block 41 lifts the gear ring 3.

[0086] The outer wall of the base 5 is also provided with a stop point 53. When the toggle body 42 slides to the end of the slide groove 52, the toggle body 42 is fixedly engaged with the stop point 53. Figure 31 The stop point 53 can effectively limit the random movement of the toggle body 42. The toggle body 42 can be toggled only when a certain force is applied, thereby preventing the shoelaces from loosening due to the movement of the toggle body 42 during exercise.

[0087] Please refer to the attached Figure 11 , Attachment Figure 15 To Attachment Figure 19 The inner side wall of the base 5 is also provided with a limit strip 54, and the end face of the dial 4 away from the driving cover 1 is also provided with a slider 43. The slider 43 and the end face of the dial 4 away from the driving cover 1 form a boss structure, which is overlapped with the limit strip 54, and the outer side wall of the slider 43 and the limit strip 54 are slidably matched. Figure 19 and attached Figure 22 As shown, the limit bar 54 on the base 5 limits the dial 4 from falling down, and the inner diameter of the limit bar 54 is consistent with the outer diameter of the slider 43 of the dial 4; when the dial 4 rotates, under the joint restriction of the slider 43 and the limit bar 54, the dial 4 can only rotate and will not shake left and right.

[0088] The inner wall of the base 5 is also provided with a limit block 55, and the outer edge of the ring gear 3 is also provided with a limit groove 34. The limit block 55 is accommodated in the limit groove 34 to prevent the ring gear 3 from rotating relative to the base 5. This ensures that the ring gear 3 only moves in the vertical direction and does not rotate, thereby improving the reliability of use.

[0089] During installation, the outer diameter of the dial 4 is consistent with the inner diameter of the base 5. When the dial 4 is placed in the base 5, the notch 44 on the dial 4 needs to be aligned with the limit block 55 on the base 5, and the moving body 42 on the dial 4 must also be close to the slide groove 52 of the base 5 for smooth assembly. Figure 18 As shown, when the dial 4 is placed in the base 5, due to the limitation of the slide slot 52, the dial 4 can only rotate a corresponding degree, and therefore will no longer contact the limit block 55. Figure 19 FIG. 4 shows a situation where the moving body 42 of the dial 4 is restricted to slide in the slide groove 52 of the base 5. Figure 20 and attached Figure 21As shown, by rotating the dial 4, the matching block 33 of the gear ring 3 and the top block 41 of the dial 4 are separated from each other, and the gear ring 3 can only move downward along the axial direction under the push of the elastic arm 32 and the restriction of the limit block 55 of the base 5. After the gear ring 3 moves downward, it is separated from the storage turntable 2 and does not contact each other. At this time, the storage turntable 2 can rotate freely without the restriction of the ratchet 31. As shown in the attached figure Figure 22 As shown, when the top block 41 of the dial 4 and the matching block 33 of the gear ring 3 are separated, the gap between two adjacent limiting strips 54 provides space for the matching block 33, so that the matching block 33 can be lowered to a sufficient position to be separated from the storage turntable 2.

[0090] When assembling, please refer to the attached Figure 23 To Attachment Figure 28 First, attach Figure 23 It shows that the shoelaces and other ropes are inserted through the through hole 51 of the base 5; secondly, the attached Figure 24 The dial 4 is shown to be placed into the base 5 along the stopper 55 of the base 5; then, Figure 25 The gear ring 3 is shown to be placed into the base 5 along the limit block 55 of the base 5; Figure 3 and attached Figure 4 , insert the hook 11 of the driving rotary cover 1 into the mounting hole 26 of the storage turntable 2 and snap it together; the next step, as shown in the attached Figure 26 As shown, the shoelaces or other ropes are passed through the rope winding hole 25 of the storage turntable 2, wound and knotted; in the next step, the assembly of the driving cover 1 and the storage turntable 2 is inserted into the base 5, as shown in the attached Figure 28 As shown, the buckling piece 12 on the driving rotary cover 1 and the buckling edge 56 on the base 5 are buckled with each other, and the buckling column 24 of the storage turntable 2 and the buckling ring 57 of the base 5 are buckled with each other, completing the entire assembly process of the rope-free knob.

[0091] Please refer to the attached Figure 29 To Attachment Figure 32 , when using, if attached Figure 29 As shown in the figure, turn the driving cover 1 counterclockwise (counterclockwise or clockwise depending on whether it is placed on the left foot or the right foot) to tighten the shoelaces; Figure 30 As shown in FIG. 1 , the toggle body 42 of the dial 4 is toggled clockwise. Due to the tension of the tight shoelaces, the driving cover 1 and the storage turntable 2 rotate in opposite directions, thereby quickly loosening the shoelaces. Figure 31 As shown, the stop point 53 of the base 5 serves to limit the random movement of the toggle body 42. The toggle body 42 can be toggled only by applying a certain force, thereby preventing the shoelaces from loosening suddenly during exercise. Figure 32 As shown, the toggle body 42 is toggled counterclockwise to reset, and only after resetting can the driving rotary cover 1 be rotated to tighten the shoelaces.
