Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, specifically to a cuff structure. Background Technology
[0002] Currently, most clothing (such as shirts, casual wear, etc.) has cuffs that include vents and buttons. In leisure or work situations, the cuffs are usually rolled up to avoid getting them dirty. When rolling up existing cuffs, the stiffer part of the cuff is usually used as the core, and the cuffs are repeatedly folded and rolled up. However, the folded cuffs are easy to fall apart or slip, which affects the wearer's movement and easily causes the cuffs to get dirty. Utility Model Content
[0003] In order to solve the technical problems in the related technologies, this utility model provides a cuff structure that makes the rolled-up cuff more stable and less likely to fall off or slip, so as to avoid the cuff getting dirty or affecting the wearer's activities.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A cuff structure includes a sleeve and an open sleeve vent. The open sleeve vent includes a connecting section and a sleeve vent body. The two ends of the connecting section are respectively connected to the sleeve and the sleeve vent body. A first vent is provided on the connecting section. A second vent communicating with the first vent is provided on the sleeve vent body. Corresponding buttons and buttonholes are provided on both sides of the sleeve vent body corresponding to the second vent. The cuff structure also includes an elastic cord and a snap fastener. The elastic cord passes through the connecting section, with one end of the elastic cord embedded in the connecting section. The other end of the elastic cord extends into the first vent and forms a snap fastener loop. The snap fastener loop is located inside the connecting section, and the snap fastener loop is configured to be detachably snapped onto the snap fastener loop.
[0006] Optionally, the snap rope end includes a connecting rope and a ball-shaped rope end, with both ends of the connecting rope connected to the inner side of the connecting section and the ball-shaped rope end, respectively, and the radial dimension of the connecting rope being smaller than the radial dimension of the ball-shaped rope end.
[0007] Optionally, the snap rope ends are provided in at least two, and the at least two snap rope ends are spaced apart on the connecting section along the extension direction of the elastic rope.
[0008] Optionally, the elastic cord is positioned at one end of the connecting section near the sleeve, and the buckle ring abuts against the two sides of the connecting section corresponding to the first slit when not fastened to the buckle cord end.
[0009] Optionally, the inner diameter L1 of the fastening ring satisfies: 0.5 cm ≤ L1 ≤ 1 cm.
[0010] Optionally, the elastic rope installed in the connecting section includes several first rope segments and several second rope segments, which are connected one-to-one at intervals. The radial dimension of the first rope segment is smaller than that of the second rope segment. Several fixing ropes are provided in the connecting section, and each end of each second rope segment is provided with two fixing ropes to limit the second rope segment. The fixing ropes are connected to the connecting section.
[0011] Optionally, the second rope, furthest from the fastening ring, is connected to the connecting segment.
[0012] Beneficial effects:
[0013] 1. Through the above technical solution, firstly, the cuff structure of this utility model can stably maintain the rolled-up sleeve state by relying on the snap rope head and snap ring, avoiding the problem of scattering or slipping, and thus effectively avoiding the problem of affecting the wearer's activities or the cuff getting dirty.
[0014] Secondly, compared with the existing cuff structure, this utility model has made minor modifications and added fewer structures. Compared with the existing related technical solutions, it has the advantages of simple structure, low processing difficulty, and low manufacturing cost.
[0015] Third, when worn normally, the structure inside the connecting section only has the end of the fastening cord, which will not cause discomfort or foreign body sensation to the wearer. Furthermore, when the sleeves are rolled up, the end of the fastening cord and the fastening ring are rolled up (hidden) inside the rolled-up sleeve structure, with no exposed structure. This will not cause problems such as entanglement or snagging with external objects, nor will it affect the overall design of the garment.
[0016] 2. Other beneficial effects or advantages of this utility model will be described in detail in conjunction with the specific structure in the specific embodiments. Attached Figure Description

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0029] In the description of this utility model, it should be noted that the terms used, such as "top surface" and "bottom surface," refer to the side of the cuff structure facing upwards in the use state as the top surface and the side facing downwards as the bottom surface; the terms used, such as "first" and "second," are only for distinguishing descriptions and do not indicate or imply a difference in importance or order; the terms used, such as "inner" and "outer," refer to the inner and outer contours of a specific outline. The use of the above terms is only for the purpose of clearly and simply describing the technical solution of this utility model and should not be construed as a limitation of this utility model.
[0030] To facilitate a clearer and more accurate understanding of the technical solution of this utility model by those skilled in the art, the following section will first provide a more detailed explanation of the existing related technologies and their technical problems.
[0031] Please see Figure 1 Taking a shirt as an example, the existing shirt cuff structure generally includes a sleeve and an open sleeve vent (the open sleeve vent includes a relatively stiff cuff and a transition connecting section connected to the sleeve, wherein the relatively stiff cuff is the sleeve vent body of this utility model, and the transition connecting section is the connecting section of this utility model, both of which have vents). When rolling up, the relatively stiff cuff is used as the folding center, and the cuff is rolled up layer by layer.
[0032] However, the cuffs are prone to coming undone or slipping after being folded up (i.e., partially coming undone, for example, the rolled-up part of the sleeve comes undone and slips down to the user's forearm), which will affect the user's movement and also make the cuffs dirty.
[0033] Regarding this problem, there are already targeted improvement solutions in the existing related technologies. For example, the announcement number CN21570636U (a loose casual shirt with convenient rolled-up sleeves) improves the button structure and adds elastic cords to make the rolled-up cuffs less likely to fall apart. At the same time, the structure of the adhesive strip, elastic strip, hook and loop fastener, hook and loop fastener, and fixing ring on the inside of the sleeve tube ensures that the length of each rolled-up sleeve is the same, increases the aesthetics, and fixes the rolled-up sleeve.
[0034] However, it has the following problem:
[0035] First, the change from a button structure to a four-button snap fastener (male and female) increases manufacturing costs and processing difficulty. Second, the actual securing effect of the elastic cord for the cuff is poor. This is because the elastic cord is placed in the relatively stiff cuff area, and it doesn't form a closed structure. The tension of the elastic cord is along its axis. For a rolled-up sleeve, this tension doesn't strengthen the fit of the sleeve over the user's arm; it only slightly improves the structural strength of the relatively stiff cuff. In other words, the elastic cord only slightly enhances the structural strength of the already structurally strong cuff, contributing very little to the stability of the rolled-up sleeve. Therefore, the actual securing effect of the elastic cord for the cuff is poor. (In fact, the elastic cord is equivalent to adding a structural reinforcing rib to the relatively stiff cuff.)
[0036] Secondly, the adhesive strips, elastic strips, hook and loop fasteners, and fixing rings on the inside of the sleeves, while effectively securing rolled-up sleeves, are complex and impractical. Furthermore, their placement on the inside of the sleeves can cause discomfort and a feeling of something in the arm when the sleeves are not rolled up, negatively impacting the wearing experience. In addition, when the sleeves are rolled up, these structures are exposed, making them prone to tangling and snagging with objects, and also affecting the overall design of the garment.
[0037] In view of this, the present invention provides a novel solution, namely the cuff structure of the present invention. The cuff structure provided by the present invention can not only effectively maintain the stability of the rolled-up sleeve state, but also has a simple structure, low processing difficulty, and low manufacturing cost. In addition, it can effectively ensure the comfort of the wearer in the normal wearing state, and there is no exposed structure in the rolled-up sleeve state.
[0038] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] like Figures 2 to 8As shown, this embodiment provides a cuff structure 100, including a sleeve tube 1 and an open sleeve slit 2. The open sleeve slit 2 includes a connecting section 21 and a sleeve slit body 22. The two ends of the connecting section 21 are connected to the sleeve tube 1 and the sleeve slit body 22, respectively. A first slit 211 is provided on the connecting section 21, and a second slit 221 communicating with the first slit 211 is provided on the sleeve slit body 22. The sleeve slit body 22 has two sides corresponding to the second slit 221. Each cuff structure 100 is provided with corresponding buttons 222 and buttonholes 223. The cuff structure 100 also includes an elastic cord 3 and a snap fastening cord head 4. The elastic cord 3 is inserted into the connecting section 21 and one end of the elastic cord 3 is embedded in the connecting section 21. The other end of the elastic cord 3 extends into the first slit 211 and forms a snap fastening ring 31. The snap fastening cord head 4 is located inside the connecting section 21. The snap fastening ring 31 is configured to be separably snapped onto the snap fastening cord head 4.
[0040] To facilitate understanding by those skilled in the art, the following description, in conjunction with the accompanying drawings, explains how the cuff structure 100 of this utility model achieves a stable sleeve rolling process.
[0041] First, in normal wearing condition (without rolling up the sleeves) as follows: Figure 2 As shown, if a sleeve roll-up operation is required, the sleeve slit body 22 can be rolled up outside the connecting section 21 first (e.g., Figure 5 (As shown), and then roll the connecting section 21 and the sleeve vent body 22 together over the sleeve tube 1 (as shown). Figure 6 As shown), at this time, the inner side of the connecting section 21 (the side closer to the wearer's skin) is turned outward, and correspondingly, the buckle head 4 set on the inner side of the connecting section 21 is exposed to the outside. At this time, the buckle ring 31 of the elastic cord 3 can be easily fastened to the buckle head 4. In this way, the elastic cord 3 and the buckle head 4 will make the radial dimension of the connecting section 21 smaller so that it can more reliably adhere to the user's arm. Subsequently, the rolled-up sleeve base with the relatively stiff sleeve body 22 as the core and the relatively soft connecting section 21 as the outer edge can be folded multiple times according to actual needs.
[0042] During this process, due to the fixing effect of the snap rope head 4 and the snap ring 31, the rolled-up sleeve base, which is based on the relatively rigid sleeve slit body 22 and has the relatively soft connecting section 21 as the outer edge, is not easy to fall apart. Based on this rolled-up sleeve base, the rolled-up sleeve state after multiple folds is also not easy to fall apart or slip apart. At the same time, since the snap rope head 4 and the snap ring 31 will be hidden inside the rolled-up sleeve after multiple folds, there is no exposed structure.
[0043] Through the above technical solution, firstly, the cuff structure 100 of this utility model can stably maintain the rolled-up sleeve state by relying on the snap rope head 4 and the snap ring 31, avoiding the problem of scattering or slipping, and thus effectively avoiding the problem of affecting the wearer's activities or the cuff getting dirty.
[0044] Secondly, compared with the existing cuff structure 100, the present invention has made minor modifications and added fewer structures. Compared with the existing related technical solutions, it has the advantages of simple structure, low processing difficulty, and low manufacturing cost.
[0045] Third, in the normal wearing state, the structure located inside the connecting section 21 is only the fastening cord end 4, which will not cause discomfort or foreign body sensation to the wearer. Furthermore, in the rolled-up sleeve state, the fastening cord end 4 and the fastening ring 31 are rolled up (hidden) inside the rolled-up sleeve structure, with no exposed structure. This will not cause problems such as entanglement or hooking with external objects, nor will it affect the overall design of the garment.
[0046] In this embodiment, it should be noted that, compared with the prior art (CN21570636U), the fixing mechanism of this utility model is as follows: when the user pulls out the buckle ring 31 at the end of the elastic cord 3 and fastens it onto the buckle head 4, the elastic cord 3, which was originally loosely threaded in the connecting section 21, is tightened. Because the elastic cord 3 is elastic, the resulting contraction force acts directly on the rolled-up sleeve 1 portion (i.e., the connecting section 21 and the sleeve 1 near it) wrapped around the user's forearm, rather than on the relatively rigid sleeve body 22 as in the prior art. Thus, the contraction force of this utility model can more tightly contract and fix the sleeve body 22 and the connecting section 21, thereby effectively resisting the tendency of the cuff to slip down due to gravity or movement. This overcomes the shortcomings of the prior art (CN21570636U), which places the elastic structure on a rigid cuff and has an unreasonable direction of fixing force, resulting in poor actual fixing effect.
[0047] Furthermore, in this embodiment, setting the point of application and operation of the contraction force on the connecting section 21, rather than on the relatively stiff sleeve slit body 22, is one of the core improvements of this invention. The connecting section 21 is the transition part between the sleeve tube 1 and the sleeve slit body 22, and is usually made of the same or similar fabric as the sleeve tube 1, making it more flexible and elastic. Applying a tightening force here can more closely wrap the arm, and the fixing effect is far better than applying a contraction force to the already relatively stiff sleeve slit body 22.
[0048] In this embodiment, it is understood that, firstly, the cuff structure 100 of this utility model can be applied to any garment with similar cuffs, such as shirts, casual wear, coats, etc., and this utility model does not make any specific limitation in this regard.
[0049] Secondly, the buckle head 4 can be made of the same material as the cuff, or it can be made of a single material (e.g., cotton, linen, wool, silk, polyester, nylon, viscose fiber, acetate fiber, etc.). This utility model does not make any specific limitation in this regard.
[0050] In one embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 6 As shown, the snap rope head 4 of this utility model may include a connecting rope 41 and a ball-shaped rope head 42. The two ends of the connecting rope 41 are respectively connected to the inner side of the connecting section 21 and the ball-shaped rope head 42. The radial dimension of the connecting rope 41 is smaller than the radial dimension of the ball-shaped rope head 42.
[0051] In this way, the connecting rope 41, with its specially designed configuration, firstly, makes the fastening and unfastening operations between the fastening ring 31 and the fastening rope head 4 more convenient, quick, and secure. Specifically, for fastening, the user simply needs to pass the fastening ring 31 through the ball-shaped rope head 42 and onto the connecting rope 41. The fastening ring 31 will then be securely fastened to the fastening rope head 4 under the combined action of the tension of the elastic rope 3 and the limiting effect of the ball-shaped rope head 42. For unfastening, the user simply needs to remove the fastening ring 31 from the ball-shaped rope head 42. This quick and easy fastening and unfastening operation is extremely convenient and efficient for the user.
[0052] Secondly, the ball-shaped rope end 42 is connected to the connecting section 21 via the connecting rope 41 (which is deformable and rotatable), giving it a certain degree of freedom of movement. This allows the ball-shaped rope end 42 to move within a certain range, making it easier for the user to find and grasp with their fingers when fastening or unfastening. After fastening, this flexible connection also better adapts to arm movements, reducing direct tension on the fixing point and making the overall structure more durable.
[0053] Third, the ball-shaped cord head 42 has a small overall volume and a smooth outer surface (without sharp edges), so the wearer will not experience any discomfort or foreign body sensation (or only a slight foreign body sensation) when wearing it, which can effectively ensure wearing comfort.
[0054] In one embodiment of this utility model, such as Figure 3 and Figure 6 As shown, the snap rope head 4 of this utility model is configured as at least two, and at least two snap rope heads 4 are spaced apart on the connecting section 21 along the extension direction of the elastic rope 3.
[0055] In this way, the at least two snap rope ends 4 can provide different tightness of the rolled-up sleeve. Users can choose to fasten the snap ring 31 to different snap rope ends 4 according to the thickness of their arms, their personal preference for tightness, or the different heights of the rolled-up sleeve. This can effectively ensure the universality and user applicability of the cuff structure 100.
[0056] In one embodiment of this utility model, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the elastic cord 3 of this utility model can be positioned at one end of the connecting section 21 near the sleeve 1, and the buckling ring 31 abuts against the two sides of the connecting section 21 corresponding to the first slit 211 when it is not buckled with the buckling cord head 4.
[0057] In this way, firstly, by setting the position of the elastic cord 3 at one end of the connecting section 21 close to the sleeve tube 1, the tightening force is directly applied to the root of the rolled-up sleeve tube 1 (that is, the lower part of the rolled-up sleeve base with the relatively rigid sleeve body 22 as the core and the relatively soft connecting section 21 as the outer edge), which can effectively make the contraction force of the elastic cord 3 resist the cuff from falling off or slipping.
[0058] Secondly, when the buckle ring 31 is not in use (not fastened to the buckle cord head 4), it is always located inside the first slit 211, and at the same time, it abuts against the connecting section 21 on both sides of the first slit 211. Firstly, this allows the buckle ring 31 to be located in a position that is easy to see and easy to grab with fingers. Secondly, it can prevent the buckle ring 31 from drooping, hanging, or shaking at will, and prevent it from being unnecessarily hooked or overly exposed to external objects, thus ensuring the neatness and cleanliness of the cuff area and maintaining the overall design sense or aesthetics of the cuff.
[0059] In one embodiment of this utility model, the inner diameter L1 of the buckle ring 31 satisfies: 0.5 cm ≤ L1 ≤ 1 cm.
[0060] In this way, the buckle ring 31 is designed to ensure that it generates just the right amount of friction and clamping force when fastened, guaranteeing a secure fastening while avoiding excessive stretching that could lead to loss of elasticity or difficulty in operation. Specifically, when its size is less than the lower limit (0.5 cm), the buckle ring 31 is too small, making the fastening operation very strenuous and difficult to complete with one hand. When its size is greater than the upper limit (1 cm), the buckle ring 31 is too large, resulting in a large gap between it and the buckle cord end 4 when fastened, which cannot generate sufficient friction and clamping force. Even slight external force or arm movement may cause the buckle ring 31 to accidentally slip off the cord end, causing the fastening function to fail and failing to solve the fundamental problem of the cuff coming undone.
[0061] In one embodiment of this utility model, such as Figure 7 and Figure 8 As shown, the elastic rope 3 installed in the connecting section 21 of this utility model includes several first rope sections 32 and several second rope sections 33. The several first rope sections 32 and several second rope sections 33 are connected one after another at intervals, and the radial dimension of the first rope section 32 is smaller than the radial dimension of the second rope section 33. Several fixing ropes 5 are provided in the connecting section 21. Each end of each second rope section 33 is provided with two fixing ropes 5 to limit the second rope section 33. The fixing ropes 5 are connected to the connecting section 21.
[0062] In this embodiment, firstly, by alternately setting ropes with different radial dimensions, the elastic rope 3 achieves different elastic moduli and contractile forces in different sections. Specifically, the first rope 32, with its smaller radial dimension, is more easily stretched during tension, generating relatively less recoil force. These sections primarily function to extend the elastic stroke, allowing the entire elastic rope 3 to adapt to a wider range of arm circumference variations. The second rope 33, with its larger radial dimension, is thicker and stronger, with greater stiffness, generating a stronger recoil force during tension. These sections serve as the main load-bearing and force-applying units, providing the core force required to tighten the cuff. Thus, this composite structure ensures that the tightening force ultimately acting on the user's arm is no longer uniform but is transmitted and distributed through a series of highly elastic points (the second rope 33) and flexible connection points (the first rope 32), resulting in a more comfortable and less oppressive tightening effect.
[0063] Secondly, the fixing rope 5 limiting system specifically designed for the second rope 33 effectively solves the problems of the elastic rope 3 sliding, twisting, and curling within the fabric channel. Specifically, several fixing ropes 5 form a multi-point anchoring structure, which can firmly and precisely fix both ends of each high-load load-bearing unit (i.e., the second rope 33) to specific positions on the fabric of the connecting section 21. This not only prevents stress concentration or large displacement deformation at a certain point in the elastic rope 3 during repeated stretching and retraction, but also ensures that the behavior of the entire elastic system is consistent and predictable in every operation. Furthermore, it ensures that each segment of the elastic rope 3 (the first rope 32 and the second rope 33) is always in its designed working position and state, thereby ensuring that its segmented tension control function can be reliably realized.
[0064] In one embodiment of this invention, the second rope 33, furthest from the fastening ring 31, is connected to the connecting section 21. This allows the elastic rope 3 to form a more stable composite structure with one end fixed and multiple points of restraint in the middle, ensuring that the contractile force of the elastic rope 3 can be efficiently and completely used to tighten the cuff.
[0065] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
