Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of underwear, more particularly to a flat flexible support ring, a setting mold thereof and a corset. BACKGROUND

[0002] With the increasing of material life level, the modern women who love beauty prevent breast ptosis, ensure the plumpness of chest or show perfect chest type, and the requirements for brassieres are higher and higher. The existing brassieres, body shaping clothes and other female underwear are mainly made of cloth, and the cloth is comfortable to wear, and in order to better improve the support of the underwear to the breast, an arc-shaped steel ring is arranged on the underwire of the brassiere. There is a difficult contradiction in the rigidity (hardness) of the arc-shaped steel ring: if a steel ring with high rigidity is used, although it has higher supporting force and better shaping effect, its softness is poor, and when the underwear is worn, the steel ring will form a steel ring indentation around the breast, reducing the comfort of the user; if a steel ring with low rigidity is used, although the steel ring is softer and more comfortable to wear, the steel ring is prone to deformation and distortion after long-term use, thereby making the underwear not fit the body and reducing the wearing comfort. Especially during the washing process, the steel ring is prone to deformation. In the prior art, the arc-shaped steel ring often uses a single steel ring structure, and various cross-section designs are used to balance the support and softness, but the effect varies from person to person. In addition, although the existing arc-shaped steel ring is covered with cloth tubes or velvet, the two ends of the steel ring are easily pierced through the cloth tubes or velvet and injure the user when worn, and the use is not safe. SUMMARY

[0003] The utility model aims at overcoming the deficiency of at least one of the prior art, providing a flat flexible support ring, a setting mold thereof and a corset, which are used to solve the problem of balancing the support and softness of the corset support ring and piercing the corset, and achieve the effects of comfortable wearing, good shaping, safe use and less deformation.

[0004] The utility model takes the technical scheme that provides a flat flexible support ring, which comprises an arc-shaped support ring body, the support ring body comprises a first sub-steel wire and a second sub-steel wire which are spaced and nested, the first sub-steel wire and the second sub-steel wire are spiral and comprise a plurality of rotating units, the outer side of the support ring body is formed by the inclined addition of the rotating units of the first sub-steel wire, and the inner side of the support ring body is formed by the inclined addition of the rotating units of the second sub-steel wire.

[0005] The flat flexible support ring provided by the scheme realizes a major breakthrough in the material performance of the steel ring. On the one hand, the rigidity is enhanced by the interval nesting of the two sub-steel wires, and on the other hand, the flexibility is increased by the inclination superposition of the rotating units in the sub-steel wires, so that the flat flexible support ring has high modulus rigidity and low modulus flexibility, and the support demand and comfort demand of the bra are considered. Compared with the traditional steel ring, the flat flexible support ring is flexible and not easy to break, the pressure on the body after wearing is smaller, there is no feeling of being bound, and the angle can be adjusted at will according to the demand, which is suitable for various changes of the chest type and can keep the shaping effect by following the body movement. What is particularly important is that the unique structure design of the flat flexible support ring allows it to produce elastic bending in all directions or even 360-degree winding without deformation, ensuring that the product is durable.

[0006] Further, the number of rotating units of the first sub-steel wire and the second sub-steel wire is 60-200, and the interval between adjacent rotating units is the diameter of the rotating unit. Increasing the number of rotating units enhances the flexibility of the flat flexible support ring; limiting the interval between adjacent rotating units to the diameter of the rotating unit can reduce the gap and increase the mechanical strength.

[0007] Further, the diameter of the first sub-steel wire and the second sub-steel wire is 0.6-1.2 mm, and the width of the support ring body is 3-6 mm and the thickness is 1.0-2.0 mm. Limiting the diameter of the sub-steel wire and the overall size of the support ring body is conducive to the flat flexible support ring to achieve appropriate modulus and volume, and to consider the support strength and flexible comfort characteristics.

[0008] Further, the support ring body is provided with through holes. Since the first sub-steel wire and the second sub-steel wire are nested at intervals, a plurality of through holes are formed therebetween, which can enhance the ventilation and heat dissipation function of the flat flexible support ring.

[0009] Further, the material of the support ring body is metal, plastic and / or other materials suitable for underwear.

[0010] Further, the flat flexible support ring further comprises an end sleeve, and the end sleeve is wrapped on both ends of the support ring body. The end sleeve can provide protection to prevent the flat flexible support ring from piercing the bra at both ends, ensuring safety in use.

[0011] Further, the flat flexible support ring further comprises a coating layer, and the coating layer is wrapped on the surface of the support ring body. The coating layer provides further safety protection while enhancing the flexibility and comfort of the flat flexible support ring.

[0012] Further, the central angle of the arc of the support ring body is less than 180°, and the included angle of the tangent lines of the two end points is 30°-60°. The central angle of the arc is less than 180°, i.e. the two ends of the arc are open outward.

[0013] Further, the distance between the two end points of the support ring body is 110-220 mm. The above-mentioned angle and size restrictions make the flat flexible support ring more fit the female breast curve, further improving the comfort.

[0014] Another purpose of the utility model lies in providing a bra, which comprises a bra body and the above-mentioned flat flexible support ring.

[0015] Another purpose of the utility model lies in providing a sizing mold for manufacturing the flat flexible support ring, which comprises:

[0016] a bottom plate;

[0017] a sizing plate, which is erected and fixed on the bottom plate and has an arc-shaped cross section, the sizing plate comprising a first edge, an arc-shaped part and a second edge, the first edge being inwardly rolled to form a first positioning groove, and the second edge being provided with a second positioning groove; and

[0018] an arc-shaped pressing plate, which is in close contact with the arc-shaped part of the sizing plate and is placed in the first positioning groove and the second positioning groove at two ends respectively;

[0019] the bottom plate, the sizing plate and the arc-shaped pressing plate jointly form a positioning space, and the positioning space has a certain height.

[0020] During the manufacturing process, the support ring body is placed in the positioning space of the above-mentioned sizing mold, so that it is bent and tightly contacts the arc-shaped part of the sizing plate, and is pressed tightly by the arc-shaped pressing plate, and then is heated for a certain time and cooled. The support ring body after sizing is allowed to be elastically bent in various directions or even 360-degree rolled without deformation, and is durable. The positioning space has a certain height, which facilitates the stacking of multiple support ring bodies on the curved surface for batch heating and sizing, improving the efficiency of sizing processing.

[0021] Further, the second edge is inwardly rolled to form the second positioning groove.

[0022] Further, the sizing mold further comprises an outwardly bent part and an L-shaped plate, the outwardly bent part being connected to the second edge and being outwardly bent, and the L-shaped plate being erected on the bottom plate and having an L-shaped cross section, a first wing of the L-shaped plate being in close contact with the outwardly bent part of the sizing plate and being connected by a fixing member, and a second wing of the L-shaped plate and the arc-shaped part of the sizing plate jointly forming the second positioning groove. The above-mentioned structure makes the L-shaped plate detachable, and when used, the distance between the L-shaped plate and the sizing plate is adjusted, which facilitates the placing and taking out of the support ring body from the sizing mold and the adjustment of the degree of compression of the support ring body.

[0023] Further, the shaping mold further comprises a pressing block or a second pressing plate, the pressing block or the second pressing plate is provided with a through hole, the upper bottom surface of the shaping plate is provided with a screw hole corresponding to the position of the through hole, and the pressing block or the second pressing plate is connected with the shaping plate through a screw. The pressing block or the second pressing plate is used for fixing the arc-shaped pressing plate in the positioning space together with the shaping plate, so that the arc-shaped pressing plate can further press the support ring body, and the heating and shaping in the mold are completed.

[0024] Further, the center angle of the cross section of the positioning space is greater than 180 degrees, and the included angle of the tangent lines of the two end points of the shaping plate is 60-90 degrees. The center angle of the arc is greater than 180 degrees, that is, the opening at the two ends of the arc is inwardly recessed. Due to the rebounding property of the support ring body after bending, the bending angle during shaping, that is, the curvature of the arc-shaped part of the shaping plate, should be greater than the target curvature; after the shaping is completed, the support ring body rebounds, and the target curvature can be achieved.

[0025] Compared with the prior art, the utility model has the advantages that:

[0026] The flat flexible support ring provided by the utility model is formed by two sub steel wires which are spaced and nested, high modulus rigidity and low modulus flexibility are combined, and the breast support ring is comfortable, has good shaping effect and is safe in use.

The utility model takes into account the support and comfort of the breast support ring, is safe, durable, not easy to deform and has high application and promotion value.

DETAILED DESCRIPTION

[0035] The drawings of the utility model are only used for example explanation and cannot be understood as the limitation of the utility model. In order to better explain the following examples, some components of the drawings can be omitted, enlarged or reduced, and the size of the actual product is not represented; for the person skilled in the art, it is understandable that some known structures and their description in the drawings can be omitted.

[0036] Example 1

[0037] The embodiment provides a chest garment, which comprises a chest garment body and a flat flexible support ring.

[0038] As shown in Figure 1 and Figure 2 The flat flexible support ring comprises an arc-shaped support ring body 100, the support ring body 100 comprises a first sub steel wire 110 and a second sub steel wire 120 which are nested and spaced, the first sub steel wire 110 and the second sub steel wire 120 are both spiral and comprise a plurality of rotating units, the outer side of the support ring body is formed by the inclined superposition of the rotating units of the first sub steel wire, and the inner side of the support ring body is formed by the inclined superposition of the rotating units of the second sub steel wire.

[0039] The flat flexible support ring provided in this embodiment represents a significant breakthrough in the performance of support ring materials. On one hand, it enhances rigidity through the interlocking of two sub-steel wires; on the other hand, it increases flexibility through the tilted superposition of rotating units within the sub-steel wires. This allows the flat flexible support ring to possess both high modulus rigidity and low modulus flexibility, balancing the support and comfort requirements of a bra. Compared to traditional support rings, the flat flexible support ring is highly deformable and less prone to breakage. Its angle can be adjusted freely to adapt to various breast shapes, providing a comfortable, unrestricted feel. Most importantly, the unique structural design of the flat flexible support ring allows it to elastically bend in all directions and even roll up 360 degrees without deformation, ensuring product durability.

[0040] The first sub-wire 110 and the second sub-wire 120 each have 60 to 200 rotating units, and the spacing between adjacent rotating units is equal to the diameter of the sub-wire itself. Increasing the number of rotating units enhances the flexibility of the flat flexible support ring; limiting the spacing between adjacent rotating units to the diameter of the sub-wire reduces gaps and increases mechanical strength.

[0041] The diameters of the first sub-wire 110 and the second sub-wire 120 are both 0.6~1.2 mm, and the width of the support ring body 100 is 3~6 mm, and the thickness is 1.0~2.0 mm. These restrictions on the diameter of the sub-wires and the overall dimensions of the support ring body help the flat, flexible support ring achieve a suitable modulus and volume, balancing support strength with flexibility and comfort.

[0042] The support ring body 100 is provided with through holes. Since the first sub-steel wire 110 and the second sub-steel wire 120 are nested at intervals, multiple through holes are formed between them, which can enhance the ventilation and heat dissipation function of the flat flexible support ring.

[0043] To ensure safety during use, the flat flexible support ring also includes an end sleeve 200, which can prevent the two ends of the flat flexible support ring from puncturing the bra, thus ensuring safety during use.

[0044] To further improve comfort, such as Figure 3 As shown, the central angle of the arc of the support ring body 100 is less than 180°, and the included angle α between the tangents at the two endpoints is 30°~60°. The central angle of the arc is less than 180°, meaning the two ends of the arc open outwards. The distance between the two endpoints of the support ring body 100 is 110~220 mm. These angle and size limitations make the flat, flexible support ring fit the curve of a woman's breasts better, further improving comfort.

[0045] This embodiment also provides a method for manufacturing the flat flexible support ring, including the following steps:

[0046] S1, take two springs with the same size and opposite rotation directions, and then embed them in a staggered manner, and then press them to be flat to generate permanent deformation, and then cut off the parts not embedded at both ends to obtain nested springs;

[0047] S2, the nested springs obtained in step S1 are placed on a curved surface to be bent and shaped.

[0048] When the target curvature of the flat flexible support ring is smaller than the curvature of the curved surface, the manufacturing method further comprises the following step: S3, after shaping, the support ring body is released to form, and the curvature becomes smaller to reach the target curvature. Due to the nature of the support ring body after bending, the bending angle when shaping, i.e. the curvature of the curved surface, should be greater than the target curvature; after shaping is completed, it is taken out, and the support ring body rebounds, i.e. the target curvature is reached.

[0049] As shown in Figure 4 , when the support ring body 100 is bent and shaped on the curved surface, the central angle of the arc of the support ring body 100 is greater than 180°, and the included angle β of the tangent lines of the two end points of the curved surface is 60°-90°. The central angle of the arc is greater than 180°, i.e. the opening of the arc at both ends is inward.

[0050] The shaping method of step S2 is to cool and shape after heating the support ring body 100, the heating temperature is 450℃, and the time length is 30 min. By heating and tempering, the support ring body 100 after shaping allows 360-degree free winding without deformation. Suitable temperature and time length are beneficial to enhance the shaping effect. After heating, an oxide layer is formed on the surface of the support ring body 100, which is beneficial to protect the surface of the support ring body 100 from erosion and oxidation, and significantly prolong the service life.

[0051] In step S2, a plurality of support ring bodies 100 are stacked on the curved surface to be bent and shaped. It is convenient for batch shaping, and improves the efficiency of shaping treatment.

[0052] Example 2

[0053] The difference between this embodiment and example 1 is that the end sleeve 200 is replaced by a cladding layer 300, as shown in Figure 3 . The cladding layer 300 provides further safety protection, while enhancing the flexibility and comfort of the flat flexible support ring.

[0054] Example 3

[0055] As shown in Figure 5 , this embodiment provides a shaping mold for manufacturing a flat flexible support ring as described in example 1, comprising:

[0056] a bottom plate 400;

[0057] The shaping plate 500 is erected and fixed on the bottom plate 400, and has an arc cross section, and comprises a first edge 510, an arc portion 520, and a second edge 530, wherein the first edge 510 is inwardly rolled to form a first positioning groove, and the second edge 530 is inwardly rolled to form a second positioning groove;

[0058] The arc-shaped pressing plate 600 is fitted with the arc portion 520 of the shaping plate 500, and is arranged in the first positioning groove and the second positioning groove at two ends, respectively; and

[0059] The second pressing plate 700 is provided with a through hole, the upper bottom surface of the shaping plate 500 is provided with a screw hole 521 corresponding to the position of the through hole, and the second pressing plate 700 is connected with the shaping plate 500 through a screw passing through the through hole;

[0060] The bottom plate 400, the shaping plate 500, and the arc-shaped pressing plate 600 enclose a positioning space, and the positioning space has a certain height.

[0061] The central angle of the cross section of the positioning space is greater than 180°, and the included angle β between the tangent lines of the two end points of the shaping plate 500 is 60°-80°, and the bending angle of the support ring body 100 when being shaped in the positioning space is as shown in the figure. Figure 4 The central angle of the arc is greater than 180°, that is, the opening of the two ends of the arc is inwardly recessed. The positioning space has a certain height, which facilitates the stacking of a plurality of support ring bodies 100 on the curved surface for batch heating and shaping, and improves the efficiency of the shaping process.

[0062] The bottom plate 400 is provided with a bottom hole 410, which facilitates the placement of the mold into the well furnace and the hooking out of the furnace through a hooking tool.

[0063] The shaping process of the flat flexible support ring: the support ring body 100 is arranged side by side in the positioning space of the above-mentioned shaping mold, and is bent to tightly adhere to the arc portion 520 of the shaping plate 500, the support ring body 100 is pressed by the arc-shaped pressing plate 600, the arc-shaped pressing plate 600 is pressed by the second pressing plate 700, and then heating for a certain time and cooling are performed. The shaped support ring body 100 allows 360-degree free winding without deformation, and is durable. Due to the rebounding property of the support ring body 100 after bending, the bending angle during shaping, that is, the curvature of the arc portion 520 of the shaping plate 500, should be greater than the target curvature; after the shaping is completed, the support ring body 100 rebounds, and the target curvature is achieved.

[0064] Example 4

[0065] The difference between this embodiment and example 3 is that the second positioning groove is formed in a different way.

[0066] As Figure 6 and Figure 7As shown, the shaping mold further comprises an outer bending part 540 connected with the second edge 530 and bent outward, and an L-shaped plate 550 erected on the bottom plate 400 and having an L-shaped cross section, a first wing 551 of the L-shaped plate 550 being matched with the outer bending part 540 of the shaping plate 500 and connected through a fixing member, and a second wing 552 of the L-shaped plate 550 and the arc-shaped part 520 of the shaping plate 500 forming a second positioning groove. The above structure makes the L-shaped plate 550 detachable, and in use, the distance between the L-shaped plate 550 and the shaping plate 500 is adjusted to facilitate the putting and taking of the support ring body 100 into and out of the shaping mold, and the degree of compression of the support ring body 100 is adjusted.

[0067] Embodiment 5

[0068] The difference between the present embodiment and Embodiment 3 is that the second pressing plate 700 is replaced by a pressing block (not shown in the figure).

[0069] The pressing block is provided with a through hole, and the upper bottom surface of the shaping plate 500 is provided with a screw hole 521 corresponding to the position of the through hole, and the pressing block is connected with the shaping plate 500 through a screw passing through the through hole. The function of the pressing block is to fix the arc-shaped pressing plate 600 in the positioning space together with the shaping plate 500, so that the arc-shaped pressing plate 600 can further compress the support ring body 100, thereby completing the heating and shaping in the mold.

[0070] Obviously, the above embodiments of the present application are only examples for clearly illustrating the technical scheme of the present application, and are not intended to limit the specific embodiments of the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
