Description

Fine-adjustable rope and cord retraction device and items Technical Field

[0001] The present application relates to the technical field of rope and line retracting and releasing devices, and in particular to a fine-tunable rope and line retracting and releasing device and an article. Background Art

[0002] In order to make some daily necessities suitable for different users, many daily necessities are designed with drawstrings, such as sneakers, hats, sports shirts, gloves, etc. The tightness of the items can be adjusted by tying the drawstrings. However, in daily life, the knotted drawstrings are sometimes easy to loosen and detach, such as loose shoelaces, which can easily cause dirt and tripping. In particular, young children cannot tie the drawstrings by themselves, and the elderly are weak, so bending over to tie the drawstrings is also very inconvenient and easy to cause danger.

[0003] Therefore, a rope retracting and releasing device has appeared on the market, which is used to retract and release the rope. The rope can be tightened by rotating the knob. However, when releasing the rope, this type of rope retracting and releasing device can only release the rope all at once, otherwise the rope will be stuck inside the product. Therefore, it is impossible to control the length of the tightened and released rope during use, which makes it inconvenient to use when precise control of the rope is required.

[0004] While some other cord retracting and releasing devices can fine-tune the tightening and releasing of the cord, they cannot control the total length of the tightened and released cord, causing the cord to become stuck or squeezed inside the product, resulting in product malfunction and unusability.

[0005] At the same time, there are a small number of products that use a rope to control the total length of the rope, but their structure is complex and difficult to produce and assemble, resulting in low production efficiency, high product costs, and prone to failures during operation, such as rope jamming or breaking. The product has poor operating stability, which greatly limits the use of such products.

[0006] Summary of the Invention

[0007] In view of this, it is necessary to provide a fine-tunable rope retracting and releasing device which can control the total length of rope retraction and release, has a simpler structural design and is easy to produce and assemble.

[0008] In the first aspect, the present application provides a fine-tunable rope retracting and releasing device, comprising:

[0013] A control member is provided between the winding wheel and the base, and the winding wheel is rotatably connected to the base through the control member; when the knob is rotated along a preset direction, the control member can move between the bottom plate and the top plate along the bottom plate toward the top plate or the top plate toward the bottom plate to limit the rotation distance of the winding wheel, thereby controlling the total length of the stored or released rope.

[0014] Compared with the prior art, the fine-tunable rope retracting and releasing device provided in the present application drives the winding wheel to rotate relative to the base by turning the knob, so as to store the rope in the winding area or release it from the winding area; the pawl arm and the ratchet part are arranged to abut against each other, so that the rotation distance of the winding wheel can be limited by the ratchet part when rotating, thereby accurately controlling the length of the rope stored or released by the winding wheel, that is, each time the knob is turned once, the winding wheel can store or release a certain length of rope, and when the knob is turned continuously When the winding wheel is in the rotational direction of the winding wheel, the rope can be continuously stored or released; in addition, the control member is arranged between the winding wheel and the base, and the total moving distance of the control member is limited by the bottom plate and the top plate, so as to realize the control of the total distance of the rotation of the winding wheel relative to the base, and then the total length of the rope when stored or released is controlled, so as to avoid the rope from being stuck or squeezed when it is wound in the winding area of ​​the winding wheel, so as to ensure that the product can run smoothly each time a certain distance of rope is stored or released.

[0015] Furthermore, in some embodiments, a fixing column is provided on the side of the base plate facing the first accommodating cavity, and a flange is provided on the fixing column; the control component is provided with a first mounting hole and a limiting groove connected to the first mounting hole, and when the first mounting hole is sleeved on the fixing column, the flange is located in the limiting groove; the control component is also provided with an external thread, and the winding wheel includes a main body, and a second mounting hole with an internal thread is provided on the main body, and the second mounting hole is threadedly connected to the control component; when the knob drives the winding wheel to rotate relative to the base, the winding wheel can drive the control component to move along the axial direction of the fixing column. The control member is connected to the fixed column by the limit groove and the flange, thereby limiting the rotation of the control member around the fixed column; at the same time, since the control member is threadedly connected to the winding wheel, when the winding wheel rotates around the fixed column, the control member can only move along the axial direction of the fixed column, and when the control member moves to the top plate or the bottom plate and cannot move, the winding wheel will also be unable to rotate around the fixed column, and at this time it will be impossible to receive or release the rope, thereby achieving accurate control of the total length of the received or released rope; in addition, the control member adopts this structure, which is simple in structure and has high operational stability, a simple way to control the total length of the rope, and a simple production process, especially rapid assembly, which effectively reduces production costs and improves product competitiveness.

[0016] Furthermore, in some embodiments, the winding reel further includes a first substrate provided on the main body and a second substrate spaced apart from the first substrate, the first substrate, the second substrate, and the main body forming the winding area; a third threading hole for fixing one end of a rope is provided on the main body located in the winding area, the first threading hole fixes the other end of the rope, and the rope is received in the winding area or released from the winding area through the second threading hole. Providing the first and second substrates to form the winding area allows the rope to be controlled in the receiving area of ​​the winding reel; and providing the third threading hole for fixing the rope in the winding area allows the rope to be directly received in the winding area when received.

[0017] Further, in some embodiments, the second substrate is located on the main body between the first substrate and the bottom plate, and the third threading hole passes through the main body of the winding area and the first substrate; a second driving member is provided on the side of the first substrate away from the second substrate, the first driving member is located on the side of the second driving member and abuts the first substrate, and the pawl arm is located on the side of the first driving member away from the second driving member and abuts the first substrate; the preset direction includes a first direction and a second direction, when the knob is rotated along the first direction, the first driving member abuts and drives the second driving member to drive the winding wheel to rotate around the fixed column to receive the rope; when the knob is rotated along the second direction, the first driving member abuts and drives the pawl arm to drive the winding wheel to rotate in the opposite direction around the fixed column to release the rope; when the knob stops rotating, the pawl arm abuts the ratchet portion to limit the rotation of the winding wheel. The third threading hole passes through the winding area and the first substrate, so that the knot tied when fixing the rope can be set on the first substrate, effectively utilizing the space; the second driving member is set up, which can make the first driving member more convenient and quick when driving the winding wheel, and the winding wheel can be driven by turning the knob.

[0018] Furthermore, in some embodiments, a third driving member is further provided on a side of the first substrate away from the second substrate, and the third driving member is provided on a side of the pawl arm away from the first driving member; when the knob is rotated in the second direction, the first driving member abuts against and drives the pawl arm, the pawl arm disengages from the ratchet portion, abuts against and drives the third driving member, and drives the winding wheel to rotate in the opposite direction around the fixed column to release the line. The provision of the third driving member allows the first driving member to indirectly drive the third driving portion by driving the pawl arm when the knob is rotated in the second direction, thereby driving the winding wheel to rotate in the second direction to release the line, thereby avoiding damage to the pawl arm when rotating in the second direction, thereby extending the service life of the product.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] First, please refer to Figure 1, which is a perspective view of a fine-tunable cord retracting and releasing device 1 shown in an embodiment of the present application. The fine-tunable cord retracting and releasing device 1 provided in the present application can be used for shoes, hats, gloves, helmets, medical protective gear, storage devices, ski protective gear, etc., and can be tightened and loosened with a cord. It is simple and convenient to use, especially for the elderly, children, patients, or in special scenarios.

[0050] Please refer to Figures 2 and 3. The fine-adjustable rope retracting device 1 in the embodiment of the present application includes a base 10, a winding wheel 20, a pawl disk 30, a knob 40 and a control member 50.

[0051] Please refer to Figures 4 and 5, in which the base 10 includes a bottom plate 11 and a first side plate 12 arranged on one side of the bottom plate 11. The bottom plate 11 and the first side plate 12 enclose a first accommodating cavity 13; a ratchet portion 121 is provided at one end of the first side plate 12 away from the bottom plate 11, and the ratchet portion 121 is ringed on the first side plate 12 and located in the first accommodating cavity 13; a first threading hole 14 and a second threading hole 15 for threading a rope are provided on the first side plate 12, and the second threading hole 15 is connected to the first accommodating cavity 13.

[0052] The reel 20 has a winding area 21 for receiving a line. The reel 20 is located within the first accommodating cavity 13 and is rotatably connected to the base 10. A ratchet plate 30 is located within the first accommodating cavity 13 and is connected to the reel 20. The ratchet plate 30 includes a ratchet arm 31 that moves along a ratchet portion 121 to control the length of the line received and released. When the ratchet arm 31 abuts the ratchet portion 121, the ratchet plate 30 and the reel 20 remain stationary relative to the base 10. When the ratchet arm 31 disengages the ratchet portion 121, the ratchet plate 30 and the reel 20 can rotate relative to the base 10. The knob 40 is disposed on a side of the base 10 facing the first accommodating chamber 13 and is rotatably connected to the base 10 and can rotate in a preset direction. The knob 40 includes a top plate 41 and a first driving member 42 disposed on the side of the top plate 41 facing the base 10. The first driving member 42 can drive the pawl arm 31 to disengage the ratchet portion 121 and drive the winding wheel 20 to rotate relative to the base 10 to store the line in the winding area 21 or release it from the winding area 21. The control member 50 is disposed between the winding wheel 20 and the base 10 and is rotatably connected to the base 10 via the control member 50. When the knob 40 is rotated in a preset direction, the control member 50 can move between the bottom plate 11 and the top plate 41 in a direction from the bottom plate 11 toward the top plate 41 or from the top plate 41 toward the bottom plate 11, thereby limiting the rotation distance of the winding wheel 20 and controlling the total length of the line stored or released.

[0053] Specifically, in this embodiment, the first threading hole 14 is used to fix one end of the rope, and the middle part of the rope passes through the second threading hole 15 to fix the other end of the rope on the reel 20. The end of the rope fixed to the first threading hole 14 needs to be knotted or sintered to prevent the rope from escaping from the first threading hole 14. Therefore, in this embodiment, a cavity for accommodating the knotted or sintered part of the rope is further provided on one side of the first threading hole 14. Of course, in other embodiments, the first threading hole 14 can also be other structures that can fix one end of the rope, such as a fixing ring or a fixing hook or a column or nail with a groove, etc., as long as it can fix one end of the rope.

[0054] Compared with the prior art, the fine-tunable rope retracting and releasing device 1 provided in the present application drives the winding wheel 20 to rotate relative to the base 10 by turning the knob 40, so as to store the rope in the winding area 21 or release it from the winding area 21; the pawl arm 31 and the ratchet portion 121 are arranged to abut against each other, so that the rotation distance of the winding wheel 20 can be limited by the ratchet portion 121 when rotating, thereby accurately controlling the length of the rope stored or released by the winding wheel 20, that is, each time the knob 40 is turned, the winding wheel 20 can store or release a certain length of rope, and when it is rotated continuously, the rope can be stored in or released by the winding wheel 20. When the knob 40 is turned, the winding wheel 20 can continuously store or release the rope; in addition, a control member 50 is set between the winding wheel 20 and the base 10, and the total moving distance of the control member 50 is limited by the bottom plate 11 and the top plate 41, thereby controlling the total distance of rotation of the winding wheel 20 relative to the base 10, and further controlling the total length of the rope when storing or releasing, thereby preventing the rope from getting stuck or squeezed when it is wound in the winding area 21 in the winding wheel 20, thereby ensuring that the product can run smoothly each time a certain distance of rope is stored or released.

[0055] Continuing to refer to Figures 2 to 5, a fixing column 16 is provided on the side of the bottom plate 11 facing the first accommodating cavity 13, and a flange 161 is provided on the fixing column 16. Specifically, the flange 161 is a convex strip protruding from the fixing column 16, and the convex strip extends axially along the outer periphery of the fixing column 16. In this embodiment, the control member 50 is a screw sleeve. The control member 50 is provided with a first mounting hole 51 and a limiting groove 52 connected to the first mounting hole 51. When the first mounting hole 51 is sleeved on the fixing column 16, the flange 161 is located in the limiting groove 52; the control member 50 is also provided with an external thread, and the winding wheel 20 includes a main body 22, and the main body 22 is provided with a second mounting hole 221 with an internal thread. The second mounting hole 221 is screwed to the control member 50; when the knob 40 drives the winding wheel 20 to rotate relative to the base 10, the winding wheel 20 can drive the control member 50 to move along the axial direction of the fixing column 16. The control member 50 is connected to the fixed column 16 through the limit groove 52 and the flange 161, thereby limiting the rotation of the control member 50 around the fixed column 16; at the same time, since the control member 50 is screwed to the winding wheel 20, when the winding wheel 20 rotates around the fixed column 16, the control member 50 can only move along the axial direction of the fixed column 16, and when the control member 50 moves to the top plate 41 or the bottom plate 11 and cannot move, the winding wheel 20 will also be unable to rotate around the fixed column 16, and at this time it will be impossible to receive or release the rope, thereby achieving accurate control of the total length of the received or released rope; in addition, the control member 50 adopting this structure has a simple structure and high operational stability, a simple method for controlling the total length of the rope, and a simple production process, especially rapid assembly, which effectively reduces production costs and improves product competitiveness.

[0056] For ease of understanding, the fine-tunable rope retracting and releasing device 1 provided in the embodiment of the present application has a preset direction including a first direction and a second direction. Specifically, the first direction and the second direction are two opposite directions. Based on the direction of the knob 40, the first direction is set to be clockwise and the second direction is set to be counterclockwise in this embodiment. When the knob 40 is turned clockwise, the reel 20 will retract the rope into the winding area 21; when the knob 40 is turned counterclockwise, the reel 20 will release the rope. During this process, the control member 50 will move between the bottom plate 11 and the top plate 41 along the axial direction of the fixed column 16. Take the case where the control member 50 abuts against the bottom plate 11, indicating that the rope is released and not retracted into the reel 20, as an example. Please refer to Figure 6, which is a cross-sectional view of the fine-tunable rope retracting device 1 shown in Figure 1 when it is retracted. When the knob 40 is rotated clockwise until the rope is completely retracted into the winding wheel 20, the control member 50 reaches the end of the fixed column 16 away from the bottom plate 11; when the rope needs to be released, the knob 40 is rotated counterclockwise, and the rope is released. Keep rotating the knob 40 counterclockwise until the rope is completely released. Please refer to Figure 7, which is a cross-sectional view of the fine-tunable rope retracting device 1 shown in Figure 1 when it is released. At this time, the control member 50 abuts the bottom plate 11, and the rope is completely released. The fine-tunable rope and wire retracting device 1 in the embodiment of the present application is provided with a control member 50, which can determine the total length of the rope that the winding wheel 20 can accommodate when the rope is fully retracted or released according to the distance that the winding wheel 20 rotates when the control member 50 moves axially along the fixed column 16. Therefore, the total length of the rope that the winding area 21 can accommodate during design is greater than or equal to the total length of the rope that can be retracted or released, so that when the product is in use, the rope is in a controllable state regardless of whether it is being retracted into the winding wheel 20 or released from the winding wheel 20, so that the rope can avoid being stuck or squeezed on the winding wheel 20 inside the product when being precisely tightened or released, thereby reducing the failure rate of the product and ensuring the quality of the product.

[0057] Please refer to Figures 8 and 9. The winding reel 20 also includes a first substrate 23 provided on the main body 22 and a second substrate 24 spaced apart from the first substrate 23. The first substrate 23, the second substrate 24 and the main body 22 form a winding area 21. A third threading hole 222 for fixing one end of the rope is provided on the main body 22 located in the winding area 21. The first threading hole 14 fixes the other end of the rope, and the rope is received in the winding area 21 or released from the winding area 21 through the second threading hole 15. It can be understood that the third threading hole 222 can also be other structures for fixing one end of the rope. This application uses a hole as an example. The first substrate 23 and the second substrate 24 are provided to form the winding area 21, so that the rope can be controlled in the storage area of ​​the winding reel 20. At the same time, the third threading hole 222 for fixing the rope is provided in the winding area 21, so that the rope can be directly received in the winding area 21 when it is received.

[0058] Specifically, the second substrate 24 is located on the main body 22 between the first substrate 23 and the bottom plate 11, and the third threading hole 222 passes through the main body 22 of the winding area 21 and the first substrate 23. In this embodiment, the third threading hole 222 passes through the main body 22 of the winding area 21 and the first substrate 23 to facilitate the installation of the rope on the winding reel 20. At the same time, a cavity is provided on the side of the first substrate 23 away from the second substrate 24 to facilitate the accommodation of the rope end in the knotting or sintering part, while also making full use of the space inside the product.

[0059] Please refer to Figure 10, which shows a schematic diagram of the line being released when the product is discharged. Please refer to Figures 11 and 12 together. When the knob 40 is rotated in the first direction, the first drive member 42 abuts and drives the second drive member 25 to drive the winding wheel 20 to rotate around the fixed column 16 to store the line. When the knob 40 is rotated in the second direction, the first drive member 42 abuts and drives the pawl arm 31 to drive the winding wheel 20 to rotate in the opposite direction around the fixed column 16 to release the line. When the knob 40 stops turning, the pawl arm 31 abuts the ratchet portion 121 to limit the rotation of the winding wheel 20. The third threading hole 222 passes through the winding area 21 and the first base plate 23, so that the knotting part when fixing the line can be set on the first base plate 23, effectively utilizing space. The provision of the second drive member 25 can make it more convenient and quick for the first drive member 42 to drive the winding wheel 20, so that the winding wheel 20 can be driven by turning the knob 40.

[0060] In order to enable the knob 40 to better drive the reel 20, a third driving member 26 is further provided on the side of the first substrate 23 away from the second substrate 24. The third driving member 26 is provided on the side of the pawl arm 31 away from the first driving member 42. When the knob 40 is rotated in the second direction, the first driving member 42 abuts and drives the pawl arm 31. The pawl arm 31 disengages from the ratchet portion 121, abuts and drives the third driving member 26, causing the reel 20 to rotate in the opposite direction around the fixed column 16 to release the string. The provision of the third driving member 26 allows the first driving member 42 to indirectly drive the third driving member 26 by driving the pawl arm 31 when the knob 40 is rotated in the second direction, thereby driving the reel 20 to rotate in the second direction to release the string. This can avoid damage to the pawl arm 31 during rotation in the second direction, thereby extending the service life of the product.
