Adjustment mechanism, tightening device, shoes and bags

[0001] This application claims priority to Chinese patent applications filed on January 22, 2025, with application numbers 202510106074.1 and 202520160010.5, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of daily necessities technology, specifically to an adjustment mechanism and its tightening device. Background Technology

[0003] Shoes, bras, chairs, bags, clothing, and other items often have drawstrings at their openings. To facilitate tightening or loosening the drawstrings, a drawstring reel is usually installed on the mounting surface of these items. A drawstring reel typically consists of a knob connected to a drive mechanism and a drum. One end of the rope is fixed to the drum. In use, rotating the knob drives the drum to rotate, applying tension to the rope and thus tightening it. Technical issues

[0004] In related technologies, the drum of the rope reel is generally made of rigid material. The drum is only suitable for mounting surfaces with specific shapes and angles. The relative positions and angles between different parts of the drum cannot be dynamically adjusted according to the real-time shape of the mounting surface. When the mounting surface changes shape under the action of external force, the drum and the mounting surface cannot fit well together. The drum is prone to pressing on the mounting surface, which affects the user experience. Technical solutions

[0005] This application provides a regulating mechanism, including:

[0006] Rope winder, used to rotate and wind ropes;

[0007] The driving component is used to drive the rope winding component to rotate.

[0008] The rope winding component includes multiple winding sections, with different winding sections used for winding different ropes or different parts of the same rope. The relative angle between at least two adjacent winding sections can be changed.

[0009] This application also provides a tightening device, including:

[0010] ropes and straps;

[0011] The adjustment mechanism described above is connected to the rope and tightens or loosens it.

[0012] This application also provides a shoe, comprising:

[0013] The main body and the rope, the rope being threaded through the main body; and,

[0014] The adjustment mechanism described above is located on the main body, and the winding component of the adjustment mechanism is used to wind the rope.

[0015] This application also provides a bag, including the adjustment mechanism described above. Beneficial effects

[0016] The adjustment mechanism provided in this application includes a rope winding component and a driving component. The rope winding component is used to rotate and wind the rope; the driving component is used to drive the rope winding component to rotate. When tightening the rope, the driving component drives the rope winding component to rotate, thereby causing the rope winding component to wind the rope, achieving the effect of tightening the rope. In this application, the rope winding component includes multiple winding sections, with different winding sections used to wind different ropes or different parts of the same rope. The relative angle between at least two adjacent winding sections can be changed. When the mounting surface for installing the adjustment mechanism changes shape under external force, the relative angle between at least two adjacent winding sections can change to dynamically adjust the relative position and angle between adjacent winding sections. This allows the rope winding component to adapt to mounting surfaces of different shapes, improving the fit between the rope winding component and the mounting surface, reducing the pressure caused by the rope winding component on the mounting surface, and improving the user experience.

[0027] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive distinction and have no special meaning.

[0028] This embodiment provides an adjustment mechanism 101. Please refer to Figures 1 to 5. The adjustment mechanism 101 includes a rope winding member 1 and a driving member 2. The rope winding member 1 is used to rotate and wind the rope 102, and the driving member 2 is used to drive the rope winding member 1 to rotate. The rope winding member 1 includes multiple winding portions 11. Different winding portions 11 are used to wind different ropes 102 or different parts of the same rope 102. The relative angle between at least two adjacent winding portions 11 can be changed.

[0029] In this embodiment, when tightening the rope 102, the drive member 2 drives the rope winding member 1 to rotate, thereby causing the rope winding member 1 to wind the rope 102 and achieve the effect of tightening the rope 102. In this application, the rope winding member 1 includes multiple winding portions 11. Different winding portions 11 are used to wind different ropes 102 or different parts of the same rope 102. The relative angle between at least two adjacent winding portions 11 can be changed. When the mounting surface for installing the adjustment mechanism 101 changes shape under the action of external force, the relative angle between at least two adjacent winding portions 11 can be changed to dynamically adjust the relative position and angle between adjacent winding portions 11, so that the rope winding member 1 can adapt to mounting surfaces of different shapes, improve the fit between the rope winding member 1 and the mounting surface, reduce the pressure caused by the rope winding member 1 on the mounting surface, and improve the user experience.

[0030] In this embodiment, the type of the driving component 2 is not limited. The driving component 2 can be a motor (not shown in the figure). The motor has an output shaft, one end of which is connected to the rope winding component 1. When the output shaft of the motor rotates, it can drive the rope winding component 1 to rotate synchronously around the central axis of the output shaft, so that the rope winding component 1 winds or unwinds the rope 102, achieving the effect of tightening or loosening the rope 102. For example, referring to Figure 6, the driving component 2 can be a knob assembly 21. The knob assembly 21 includes a knob cover 211 and a first gear component 212 that are connected in a transmission. The rope winding component 1 is provided with a winding part 11 and a second gear component 14 that are connected in a transmission. The first gear component 212 and the second gear component 14 are meshed together. When the knob cover 211 is rotated, the knob cover 211 can drive the first gear component 212 to rotate. When the first gear component 212 rotates, it drives the second gear component 14 and the winding part 11 to rotate, thereby causing the rope winding component 1 to wind or unwind the rope 102, achieving the effect of tightening or loosening the rope 102. For example, referring to Figure 7, the driving component 2 can be a pressure rod assembly 22, which includes a pull rod 221 and a drive shaft 222. The pull rod 221 is provided with a first transmission gear 2211, and the two ends of the drive shaft 222 are fixed with second transmission gears 2221 that mesh with the first transmission gear 2211. The middle part of the drive shaft 222 is also fixed with a third transmission gear 2222. The rope winding component 1 is provided with a winding part 11 and a fourth transmission gear 15 that are connected by transmission. When the pressure rod is pressed down or pulled up, the first transmission gear 2211 on the pull rod 221 can drive the second transmission gear 2221 to rotate. When the second transmission gear 2221 rotates, it can drive the drive shaft 222 and the third transmission gear 2222 to rotate. When the third transmission gear 2222 rotates, it drives the fourth transmission gear 15 and the winding part 11 on the rope winding component 1 to rotate, thereby causing the rope winding component 1 to wind or unwind the rope 102, achieving the effect of tightening or loosening the rope 102.

[0031] In this embodiment, the number of winding portions 11 is not limited; there can be two, three, or more winding portions 11. The shape of the winding portions 11 is also not limited; they can be cylindrical, spherical, conical, frustum-shaped, or other shapes. The material type of the winding portions 11 is not limited; they can be made of flexible or rigid materials. The size of the winding portions 11 is not limited; different winding portions 11 can have the same or different sizes, and can be set according to actual needs.

[0032] In one embodiment, at least part or all of the rope winding component 1 is made of flexible material or flexible structure. Using flexible material or flexible structure makes the rope winding component 1 easier to bend, allowing it to adapt to mounting surfaces of different shapes and improving the fit between the rope winding component 1 and the mounting surface. Simultaneously, the relatively softness of the flexible material or flexible structure reduces the pressure exerted by the rope winding component 1 on the mounting surface, improving the comfort of using the adjustment mechanism 101. In this embodiment, some of the rope winding components 1 are made of flexible material or flexible structure; alternatively, the entire rope winding component 1 may be made of flexible material, without limitation.

[0033] In one embodiment, referring to Figure 8, the rope winding member 1 further includes a flexible connector 12, and two adjacent winding portions 11 are connected by the flexible connector 12. In this embodiment, the flexible connector 12 has a certain degree of flexibility and elasticity. When the mounting surface used to install the adjustment mechanism 101 changes shape under the action of external force, the flexible connector 12 can absorb and disperse the pressure generated by the rope winding member 1 on the mounting surface, reducing the pressure of the rope winding member 1 on the mounting surface. In addition, the flexible connector 12 can bend or stretch with the change of the shape of the mounting surface to dynamically adjust the relative position and angle between adjacent winding portions 11, so that the rope winding member 1 can adapt to mounting surfaces of different shapes, improving the fit and flexibility between the rope winding member 1 and the mounting surface. Furthermore, since two adjacent winding portions 11 are connected by the flexible connector 12, under the drive of the drive member 2, multiple winding portions 11 can rotate synchronously to simultaneously tighten multiple ropes 102 or multiple parts of the same rope 102, improving the effect of the rope winding member 1 in tightening the rope 102.

[0034] In this embodiment, the type of flexible connector 12 is not limited; it can be a spring, rubber stud, rubber expansion joint, flexible sleeve, etc. The fixing method between the winding portion 11 and the flexible connector 12 is also not limited; they can be integrally formed or detachably connected.

[0035] In one embodiment, the arrangement of the driving member 2 and the winding portion 11 is not limited and can be flexibly set according to actual needs. For example, referring to Figures 1 and 3, multiple winding portions 11 can be arranged sequentially and located on the same side of the driving member 2. As another example, referring to Figures 2 and 4, the driving member 2 is disposed between two or more winding portions 11. In one embodiment, the diameter of the winding portion 11 is not limited and can be flexibly set according to actual needs.

[0036] In one embodiment, at least two winding portions 11 have different diameters. Generally, with the same number of rotations, a larger diameter of the winding portion 11 allows for a greater degree of winding of the rope 102. Having at least two winding portions 11 with different diameters can satisfy the tightening requirements of the rope 102 at different locations. For example, when the adjustment mechanism 101 is applied to a shoe, the diameter of the winding portion 11 near the toe can be smaller than the diameter of the winding portion 11 away from the toe, preventing the rope 102 near the toe from becoming overly tight and affecting the comfort of the shoe.

[0037] In one embodiment, the rope winding member 1 has a plurality of winding portions 11, each with the same diameter. In this embodiment, since each winding portion 11 has the same diameter, tightening the rope winding member 1 can make the tightness of the rope 102 in different parts the same or substantially the same, resulting in a better effect of uniformly tightening the rope 102.

[0038] In one embodiment, the adjusting mechanism 101 further includes a transmission component (not shown in the figure), which is tractively connected between the rope winding component 1 and the driving component 2. The transmission component can adjust the included angle between the rope winding component 1 and the driving component 2, so that the included angle between the rope winding component 1 and the driving component 2 can be arbitrarily adjusted. In this embodiment, on the one hand, the driving component 2 can drive the rope winding component 1 to rotate synchronously through the transmission component, thereby causing the rope winding component 1 to wind the rope 102 and achieve the effect of tightening the rope 102; on the other hand, the transmission component can adjust the included angle between the rope winding component 1 and the driving component 2 to dynamically adjust the relative position between the rope winding component 1 and the driving component 2, so that the adjusting mechanism 101 can adapt to mounting surfaces of different shapes, improving the fit and flexibility between the adjusting mechanism 101 and the mounting surface. In this embodiment, the type of transmission component is not limited, and the transmission component can be a universal joint, a spherical joint, a ball joint, etc. In this embodiment, the included angle between the rope winding component 1 and the driving component 2 is not limited. The included angle between the rope winding component 1 and the driving component 2 can be any one or any two of the following: 0°, 1°, 5°, 10°, 30°, 60°, 90°, 120°, 150°, 180°.

[0039] In another embodiment, the adjusting mechanism 101 further includes a transmission member (not shown in the figure), which is driveably connected between the rope winding member 1 and the driving member 2. The driving member 2 can drive the rope winding member 1 to rotate synchronously through the transmission member, and the included angle between the rope winding member 1 and the driving member 2 is not adjustable. For example, the transmission member is made of a rigid material and cannot be bent. The transmission member is rigidly connected to both the rope winding member 1 and the driving member 2, making the included angle between the rope winding member 1 and the driving member 2 non-adjustable.

[0040] In one embodiment, referring to FIG8, the rope winding member 1 is provided with a rope fixing part 13, which is used to fix the rope 102. In this embodiment, the number of rope fixing parts 13 is not limited; there may be one, two, or more rope fixing parts 13. The position of the rope fixing parts 13 is not limited; they may be provided on the winding part 11 of the rope winding member 1 or on the flexible connector 12 of the rope winding member 1. The number of rope fixing parts 13 on each winding part 11 is also not limited; each winding part 11 may have one or more rope fixing parts 13.

[0041] In one embodiment, there are multiple rope fixing parts 13, which are arranged at intervals along the axial direction of the rope winding member 1. In this embodiment, on the one hand, the multiple rope fixing parts 13 arranged at intervals along the axial direction of the rope winding member 1 can better distribute and fix the rope 102, ensuring that the rope 102 can be evenly arranged on the rope winding member 1 during the winding process, thereby improving the winding efficiency; on the other hand, the rope fixing parts 13 arranged at intervals along the axial direction of the rope winding member 1 can provide multiple support points for the rope 102, thereby enhancing the stability of the rope 102.

[0042] In one embodiment, the rope fixing part 13 is provided with a fixing hole, and the rope 102 can be fixed to the rope fixing part 13 through the fixing hole.

[0043] In one embodiment, the rope fixing part 13 is provided with a fixing buckle, and the rope 102 can be fixed to the rope fixing part 13 by the fixing buckle.

[0044] This application also provides a tightening device 100, as shown in Figures 1 to 5, which includes a cord 102 and an adjustment mechanism 101 as described above. The adjustment mechanism 101 is connected to the cord 102 and tightens or loosens the cord 102. The type of tightening device 100 is not limited, and the device can be a medical bandage, shoe, clothing, hat, bag, or other daily necessities.

[0045] In one embodiment, referring to Figures 1 to 4, the tightening device is a shoe, and the adjusting mechanism 101 is fixed to the shoe tongue to tighten the drawstring 102 on the shoe. The diameter of the winding portion 11 near the toe is smaller than the diameter of the winding portion 11 away from the toe, preventing the drawstring 102 near the toe from being overtightened and affecting the comfort of the shoe. In another embodiment, referring to Figure 5, the tightening device is clothing, and the adjusting mechanism 101 is fixed to the clothing to tighten the drawstring 102 on the clothing. The adjusting mechanism 101 has winding portions 11 of different diameters, allowing adjustment of the tightening degree on different parts of the clothing as needed.

[0046] In one embodiment, referring to Figures 1 to 5, the tightening device 100 further includes a body 103, a plurality of ropes 102 connected to the body 103, and a plurality of winding portions 11 arranged sequentially. Each winding portion 11 is connected to at least one rope 102. The winding portion 11 can rotate and wind or unwind the rope 102 to tighten or loosen the body 103. The body 103 is provided with a plurality of rope-passing portions 1031 through which the ropes 102 pass. The ropes 102 are passed through the corresponding rope-passing portions 1031 and fixed to the winding portion 11. When the winding portion 11 rotates, it can wind the rope 102 fixed to the winding portion 11 to tighten or loosen the body 103.

[0047] Traditional tightening devices typically include a rope that passes through different threading sections in sequence, with its end fixed to a winding member 1. When tightening the rope, the winding member applies tension to the end of the rope to tighten the main body. However, due to the rope's own elasticity and frictional contact with components such as the threading sections, the efficiency of tension transmission decreases with increasing distance. This results in better tightening of the rope near the winding member and poorer tightening of the rope further away, affecting the user experience. In this embodiment, multiple winding sections 11 are arranged sequentially, each corresponding to a different rope 102. When the winding member 1 rotates, it can simultaneously tighten or loosen the ropes 102 at different locations on the main body 103. The force applied by the winding member 1 to the ropes 102 is more uniform, resulting in a better tightening effect.

[0048] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
