Description

Technical Field

[0001] The invention relates to the field of made-to-measure bras, in particular to a bra. Background Art

[0002] The function of women's underwear is to cover and support the breasts. In daily life or during pregnancy, women's breasts will become larger to a great extent. Generally, they need to change to underwear with a larger cup size, and the original size underwear may no longer be wearable, resulting in waste. Existing women's underwear does not solve the problem of women's breast enlargement very well.

[0003] A Chinese patent application with application number 201410334196.8 published on December 24, 2014 discloses a women's bra with adjustable cup size, including two cups, wherein the two cups include a support component and a cover cloth for holding the breasts, wherein the support component is a length-adjustable structure, and the cover cloth is an area-adjustable structure for accommodating breasts of different sizes.

[0004] The above-mentioned underwear has a relatively small adjustment range and a relatively small application range. How to provide an underwear with a simple structure and adaptable to different cup sizes is a technical problem that needs to be solved. Summary of the invention

[0005] The technical task of the present invention is to provide a bra to solve the problem of how to provide a bra with a simple structure and adaptable to different cup sizes.

[0006] The present invention provides a bra, comprising a bra body mainly composed of a cup, a lower part, a back and shoulder straps, characterized in that the lower part comprises a front middle lower part, a lower part and a front side lower part connected in sequence, the front middle lower part and the front side lower part are both fixed-length and inelastic fixed parts, the lower part is an elastic deformation part, and the front lower part has lateral elasticity;

[0007] The cup includes a bra support, a cover body and a bowl binding line. The bra support is an elastic bra support consisting of a large bra support and a small bra support embedded in the large bra support. The small edges of the large bra support and the small bra support overlap, and the upper edge of the small bra support is lower than the upper edge of the large bra support. There are two bra supports in total. The cover body is an elastic cover body and is wrapped around the outside of the two bra supports. The bowl binding line has deformation but no length variable. There are two of them, namely a front middle bowl binding line and a front side bowl binding line. The front middle bowl binding line is sewn on the front middle lower part, and the front side bowl binding line is sewn on the front lower part.

[0008] In the above-mentioned embodiment, through the cooperation of large and small chest supports, the size of the large chest support is used as the design reference of the bra. For bras smaller than this standard, the small chest support can play a supporting role. As a part of the cover body, the large chest support can play a supporting role for bras larger than this standard, and the small chest support supports the chest at the lowest edge of the chest; the cover body elastically wraps the above-mentioned two chest supports, thereby forming a cup with adjustable cover body size, which can adapt to chests of different sizes; the bowl binding line replaces the steel ring of the traditional bra, the bowl binding line is soft, has no length variable but has a certain deformation, can fit with the edge of the chest, and plays a role in fixing the chest shape; in the lower lying position, the front middle lower lying and the front side lower lying are fixed-length and inelastic shaping lyings, and the lower lying has a certain amount of expansion and contraction. The lower lying position composed of these three sections ensures the length and width of the bowl binding changes, and can support the corresponding cup opening size to change when the size of the lower edge of the cup changes, so that the cup in the bra body is a universal cup, supporting A, B, C, D cups and other sizes.

[0009] Preferably, the front middle lower part and the front side lower part are both shaped yarns;

[0010] The cover body is an elastic structure composed of two layers of elastic cover cloth;

[0011] The large chest support and the small chest support are both elastic chest supports made of sandwich fabrics.

[0012] Sandwich fabrics are composed of three surfaces: upper, middle and lower. The surface is usually designed with mesh. The middle layer is MOLO yarn connecting the surface and the bottom. The bottom is usually a densely woven flat surface, commonly known as "sandwich". There is a layer of dense mesh under the fabric, so that the surface mesh will not deform too much, which enhances the fastness and color of the fabric. The mesh effect makes the fabric more modern and sporty. It is made of high-molecular synthetic fiber woven by precision machines at one time. It is durable and belongs to the fine products among warp knitted fabrics. The mesh structure of the sandwich fabric has been high-temperature finalized in the production process. When subjected to external force, it can extend in the direction of the force. When the tension is reduced and withdrawn, the mesh can return to its original shape. The material can maintain a certain elongation in the horizontal and vertical directions without loosening and deformation.

[0045] The limiting ring is used to limit the ribbon on the bra body by a detachable connection, including but not limited to: the limiting ring is detachably connected to the bra body by a Velcro fastener, or is detachably connected to the bra body by sewing.

[0046] A bra of the present invention has the following advantages:

[0047] 1. The bra is composed of a large bra and a small bra embedded in the large bra, and both are elastic. The bra body is wrapped around the outside of the two bras. The size of the cup is adjustable, and the lying position has lateral elasticity. The bra body can achieve AD cup measurement and has a wide range of applications.

[0048] 2. The material of the chest support is sandwich material, which realizes the elasticity of the chest support and supports breasts of different sizes;

[0049] 3. The bra cup wire replaces the steel ring of the traditional bra. The bra cup wire is soft and has no length variation but has a certain deformation. It can fit the edge of the chest and play the role of fixing the chest shape.

[0050] 4. A pull-wire measuring tool is provided on the bra body, which can measure the bust circumference in time;

[0051] 5. The roller, coil spring and inelastic pull wire form an automatically retractable winding mechanism. The external force drives the roller to rotate through the pull wire and pulls out the pull wire. The magnetic ring is coaxially linked with the roller. The magnetic ring rotates synchronously during the rotation of the roller. The NS magnetic pole signal of the outer diameter of the magnetic ring is obtained through the data acquisition module. The above NS stimulation signal is sent to the calculation end. The calculation end calculates the number of rotations of the magnetic ring according to the change of the NS magnetic pole signal, thereby calculating the number of rotations of the roller, and further knowing the length of the pull wire, thereby realizing measurement;

[0052] 6. A coaxial sleeve is formed on the lower end surface of the roller, and the magnetic ring is fastened on the sleeve and fixed relatively to the roller. The roller and the sleeve are sleeved on the same fixed shaft, and the roller and the magnetic ring can rotate synchronously. The above structure is simple and easy to assemble;

[0053] 7. A limiting convex edge is formed on the upper end surface of the roller, and the limiting convex edge surrounds the outer end of the roller to form a receiving groove with an opening upward, a first clamping interface is formed on the limiting convex edge, and a second clamping interface is formed on the top of the fixed shaft. The coil spring is wound in the receiving groove in the form of a plane spiral spring, and the outer end of the coil spring is in a barb shape and is snap-connected with the first clamping interface, and the inner end of the coil spring is in a barb shape and is snap-connected with the second clamping interface, so that the coaxial linkage connection between the coil spring and the roller is realized, and the coil spring is detachably fixed between the fixed shaft and the roller, and the steering of the roller can be adjusted by the cooperation of the coil spring and the pull wire, thereby realizing the automatic rewinding of the pull wire;

[0054] 8. When the data acquisition module and the control module are both assembled in the control box to form a wire gauge, the wire gauge can be used to measure a single value at a single location;

[0055] 9. The control module is assembled in a separately set control box body as a data transmitter, and the data acquisition module is assembled together with the winding mechanism, the magnetic ring, and the control box body to form a length collector. The above data transmitter and length collector form a wire drawing measuring tool, wherein there are two length collectors. When measuring the chest circumference, it is necessary to measure the upper chest circumference and the lower chest circumference. The two length collectors and a data transmitter can be combined for measurement, wherein one length collector is set at the upper chest circumference and the other length collector is set at the lower chest circumference. Both length collectors are connected to the control module, so that the upper chest circumference and the lower chest circumference can be calculated at one time;

[0056] 10. The first interfaces can be electrically connected through cables, that is, the data acquisition modules can be electrically connected to each other through their first interfaces. For a wire-drawing measuring tool composed of a length collector and a data transmitter, when there are too many length collectors, the relevant multiple length collectors are connected in pairs through their first interfaces in turn, and then the length collector at the transmission end is electrically connected to the control module, thereby avoiding that each length collector is directly electrically connected to the control module, reducing the need for too many second interfaces in the control module, and saving PCB board space;

[0057] 11. The ribbon is inelastic and connected to the drawstring, and the length of the ribbon is shorter than the length of the part to be measured. When measuring the body with the drawstring measuring tool, the ribbon and the drawstring are used as a whole to measure the chest circumference. The width of the ribbon is wider to avoid tightening the human body when measuring, which increases comfort and data accuracy.

[0058] 12. The ribbon is provided with a plurality of limiting rings, through which the ribbon is limited to the part to be measured on the human body or the corresponding clothing, and the ribbon is stretched along the line of the part to be measured, thereby avoiding the bending of the ribbon during the measurement process to affect the measurement accuracy.

[0076] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments may be combined with each other.

[0077] In the embodiments of the present invention, terms such as "fixed connection", "connected", "connection", etc. should be understood in a broad sense, indicating that it can be fixedly connected, integrally connected or detachably connected; it can be directly connected or indirectly connected through an intermediate medium. Relevant scientific research or technical personnel in this field can determine the specific meanings of the above terms in the present invention according to specific circumstances, and they should not be understood as limitations on the present invention.

[0078] In the embodiment of the present invention, the term "electrical connection" means that the electrical connection refers to a circuit connection or a signal connection with physical contact, and the connection is made through a physical line such as PCB copper foil or a wire or cable that can transmit an electrical signal.

[0079] The embodiment of the present invention provides a bra, which is used to solve the technical problem of how to provide an underwear with a simple structure and adaptable to different cup sizes.

[0080] Embodiment 1:

[0081] Figure 1-3 As shown, a bra of the present invention comprises a bra body mainly composed of a cup, a lower part, a back and shoulder straps, and the bra body is a front zipper bra. The lower part comprises a front middle lower part, a lower part and a front side lower part connected in sequence, the front middle lower part and the front side lower part are both fixed length and inelastic fixed parts, the lower part is an elastic deformation part, and the front lower part has lateral elasticity; the cup comprises a chest support, a cover body and a bowl binding line, the chest support is an elastic chest support composed of a large chest support and a small chest support embedded in the large chest support, the small edges of the large chest support and the small chest support overlap, and the upper edge of the small chest support is lower than the upper edge of the large chest support, there are two of the above chest supports, the cover body is an elastic cover body and is wrapped around the outside of the above two chest supports, the bowl binding line has deformation but no length variable, and there are two of them, namely the front middle bowl binding line and the front side bowl binding line, the front middle bowl binding line is sewn on the front middle lower part, and the front side bowl binding line is sewn on the front side lower part.

[0082] In this embodiment, both the large chest support and the small chest support are elastic chest supports made of sandwich fabrics. The sandwich fabrics are composed of three surfaces: upper, middle and lower. The surface is usually designed with meshes. The middle layer is MOLO yarn connecting the surface and the bottom surface. The bottom surface is usually a densely woven flat surface, commonly known as a "sandwich". There is a layer of dense mesh under the fabric, so that the surface mesh will not be deformed too much, thereby enhancing the fastness and color of the fabric. The mesh effect makes the fabric more modern and sporty. It is made of polymer synthetic fibers woven in one go by a precision machine. It is durable and belongs to the finest warp knitted fabrics. The mesh structure of the sandwich fabric has been subjected to high-temperature shaping in the production process. When subjected to external force, it can extend in the direction of the force. When the pulling force is reduced and withdrawn, the mesh can return to its original shape. The material can maintain a certain elongation in the horizontal and vertical directions without loosening and deforming.

[0083] The lower edge of the small bra support is sewn together with the lower edge of the large bra support in an overlapping manner. Using the unique elasticity of the sandwich, the height of the small bra support is lower than that of the large bra support. By matching the large and small bra supports, the size of the large bra support is used as the design basis of the bra. For bras smaller than this standard size, the small bra support can play a supporting role, and the large bra support becomes part of the cover cloth. For bras larger than the standard size, the large bra support can play a supporting role, and the small bra support runs to the bottom edge of the chest to support the chest. The cover body is a two-layer elastic cover cloth, which is wrapped around the outside of the above two cups.

[0084] The front middle lower part and the front side lower part are both shaping yarns, which have shaping effects. In this embodiment, the lengths of the front middle lower part and the front side lower part are fixed and have no change in the amount of expansion and contraction. The front middle lower part is made of an elastic material with strong resilience and has a certain amount of expansion and contraction. These three sections of the lower part can change the size of the lower edge of the cup, and the corresponding cup opening size also changes at the same time, so that the cup can meet the needs of A, B, C, and D cups.

[0085] At the same time, the bra bra wire replaces the steel ring of the traditional bra. The bra wire is soft and has no length variation but has a certain deformation. It can fit the edge of the chest and play a role in fixing the chest shape. The bra wire is sewn on the front middle lower part and the front side lower part, and there is no bra wire on the lower part.

[0086] In the bra body, the front middle lower part, the front side lower part and the deformable lower part ensure the length and width of the bowl can be changed, and the chest support made of sandwich material of different sizes can support the breasts of different sizes.

[0087] Embodiment 2:

[0088] The custom-made bra is a wearable bra with a front chest zipper, and a zipper is provided between two chest supports.

[0089] like Figure 4-7 As shown, a bra of the present invention is an improvement on Example 1, in which a wire measuring tool is added to realize the function of measuring chest circumference.

[0090] The wire-pulling measuring tool comprises a wire-pulling box body, a winding mechanism, a magnetic ring and a data acquisition module, wherein a accommodating space is formed in the wire-pulling box body; the winding mechanism comprises a roller, a coil spring and an inelastic wire, wherein the roller is rotatably arranged in the wire-pulling box body, the wire is wound around the roller and the free end of the wire passes through the wire-pulling box body, at least one of the two ends of the wire is a free end, the coil spring is coaxially linked to the roller in the form of a planar spiral spring, and is located between the roller and the wire-pulling box body, and is used to drive the roller to rotate so as to drive the wire to be wound around the roller through the rotating roller; the outer diameter side elevation of the magnetic ring is uniformly alternating NS magnetic poles with equal spacing, the magnetic ring is coaxially linked to the roller and rotates synchronously with the roller; the data acquisition module is located in the wire-pulling box body and is arranged at the magnetic ring, and is used to collect and output the magnetic pole change signal of the outer diameter side elevation of the magnetic ring; the wire-pulling box body, the winding mechanism, the magnetic ring and the data acquisition module cooperate to form a length collector, and the length collector is used to measure chest circumference.

[0091] In this embodiment, the wire pulling box body includes an upper shell and a lower shell, and snap-fitting slots are formed on the inner walls of the upper shell and the lower shell, and the upper shell and the lower shell are relatively snapped together through the snap-fitting slots to form a receiving space. A vertical fixed shaft is fixed inside the above-mentioned wire pulling box body, and the bottom end of the fixed shaft is fixedly connected to the inner wall of the lower shell, and the top end of the fixed shaft is located between the upper shell and the lower shell.

[0092] A shaft sleeve coaxial with the roller is formed on the lower end surface of the roller. The roller and the shaft sleeve are rotatably sleeved on the fixed shaft from top to bottom, and the magnetic ring is fixedly sleeved on the shaft sleeve, so that the roller and the magnetic ring rotate synchronously.

[0093] The coil spring is located on the upper end surface of the roller. In order to facilitate the winding of the coil spring on the upper end surface of the roller, an upward-opening receiving groove is formed on the upper end surface of the roller. The receiving groove is connected to the axial hole of the roller, the outer end of the coil spring is connected to the roller, and the inner end of the coil spring is connected to the fixed shaft.

[0094] Specifically, an upwardly protruding limiting convex edge is formed on the upper end surface of the roller, and the limiting convex edge surrounds the outer end portion of the roller in a circle to form an upwardly opening accommodating groove, a threading hole and a first card interface are formed on the limiting convex edge, and a second card interface is formed on the top of the fixed shaft, and the outer end and the inner end of the coil spring are bent into a hook shape, the outer end of the coil spring is snap-fitted with the first card interface, and the inner end of the coil spring is snap-fitted with the second card interface, the pull wire passes through the threading hole and is tightly connected to the roller, and is wound in a wire groove opened on the outer side wall of the roller. In this embodiment, two adjacent notches are provided on the limiting convex edge, and the two notches and the limiting convex edge between the notches constitute a first clamping interface, and the outer end of the coil spring is buckled and connected with the above-mentioned first clamping interface, thereby realizing a detachable fixed connection between the coil spring and the roller; the fixed shaft is hollow, and two opposite notches are provided on the top of the fixed shaft, and the two notches constitute a second clamping interface, and the inner end of the coil spring is buckled and connected with the above-mentioned second clamping interface, thereby realizing a detachable fixed connection between the coil spring and the fixed shaft and the wire pull box body.

[0095] The data acquisition module is arranged in the wire drawing box body, and is used to collect the NS magnetic pole transformation on the side elevation of the outer diameter of the magnetic ring, and output the acquired data to the calculation end, where the calculation end calculates the change in the wire drawing length according to the NS magnetic pole transformation, thereby realizing the measurement.

[0096] The data acquisition module includes a first PCB board, a Hall sensor, a first controller and a first interface. The first PCB board is located in the wire pulling box. There are two Hall sensors in total. The two Hall sensors are arranged on the first PCB board and located at the magnetic ring, and are used to collect the magnetic pole change signal of the outer diameter side elevation of the magnetic ring; the first controller is arranged on the first PCB board and is electrically connected to the Hall sensor; there is at least one first interface, and the at least one first interface is arranged on the first PCB board and is electrically connected to the first controller. The first interfaces of different data acquisition modules can be electrically connected through cables, and the cables include power supply lines and signal lines. An axial hole is opened in the middle of the first PCB board, and the axial hole is passed through the fixed shaft and is located below the roller. When installing, ensure that the two Hall sensors are located near the magnetic ring.

[0097] The data acquisition module is electrically connected to the computing end of the peripheral device through the first interface to obtain power, and at the same time sends the collected data to the computing end, where the computing end calculates the change in length of the pull wire relative to the roller winding based on the acquired data, and outputs the change in length of the pull wire.

[0098] For the front zipper bra body, there are two length collectors, namely the upper collector and the lower collector, which are arranged opposite to each other. If both ends of the pull line are free ends, two pull line boxes are arranged up and down at the middle of the back of the bra, and the two free ends of each pull line are respectively connected to one side of the corresponding zipper; if only one end of the two ends of the pull line is a free end, two pull line boxes are arranged up and down at one side of the zipper, and the free end of each pull line is connected to the other side of the zipper.

[0099] In view of the fact that the pull line required to be pulled out is long and thin for a longer chest circumference, the body feeling is not good, so a ribbon is arranged on the pull line. The ribbon is inelastic and corresponds to the data acquisition module one by one, and the length of the ribbon is less than the length of the part to be measured.

[0100] When only one of the two ends of the pull wire is a free end passing through the pull wire box, one end of the ribbon is connected to the free end of the pull wire, and the other end of the ribbon is connected to the pull wire box; when both ends of the pull wire are free ends passing through the pull wire box, the two ends of the ribbon correspond to and are connected to the two free ends of the pull wire one by one.

[0101] At the same time, there are multiple limiting rings on the ribbon, which limit the ribbon on the bra body by a detachable connection and limit the ribbon to stretch along the line of the upper bust or lower bust; the limiting ring is used to limit the ribbon on the bra body by a detachable connection, including but not limited to: the limiting ring is detachably connected to the bra body by Velcro, or is detachably connected to the bra body by sewing.

[0102] In this embodiment, a row of limiting rings made of cloth strips are sewn on the upper and lower edges of the bra body. Taking the example of a case where both ends of the pull wire are free ends, two pull wire boxes are arranged opposite to each other on the middle end of the back of the bra body. The ribbon in the upper pull wire box extends along the upper edge of the bra to the zipper through the limiting ring, and the two free ends of the pull wire are respectively detachably fixed at the two side edges of the zipper; the two pull heads of the pull wire in the lower pull wire box pass through the corresponding box bodies and are respectively detachably fixed at the two side edges of the zipper, and the ribbon extends along the lower edge of the bra to the zipper through the limiting ring.

[0103] Taking the zipper-type bra as an example, the method of using the intelligent made-to-measure bra of the present invention is as follows: put on the made-to-measure bra and zip up the zipper, the pull wire drives the roller to rotate and drives the magnetic ring to rotate under the action of the zipper, the data acquisition module in the pull wire measuring tool collects the number of revolutions of the magnetic ring and sends the number of revolutions of the magnetic ring to the calculation end, the calculation end calculates the change in the pull wire length according to the number of revolutions of the magnetic ring, combines the length of the ribbon and the change in the pull wire length to obtain the chest circumference, and sends the chest circumference length to the user electronic terminal through the data communication module, so that the chest circumference can be obtained in time through the user electronic terminal.

[0104] As an improvement, the above-mentioned wire pulling measuring tool also includes a control module, which is electrically connected to the data acquisition module, for supplying power to the data acquisition module, and for acquiring and outputting data collected by the data acquisition module; the control module and the data acquisition module correspond one-to-one and are located in the corresponding wire pulling box body; or, there is only one control module, which is located in a separately provided control box body to form a data transmitter.

The second interface is connected to the first interface through a cable, and the cable includes a power supply line and a signal line; the second controller is arranged on the second PCB board and is electrically connected to the battery and the second interface, and is used to obtain data from the data acquisition module and the collected data; the wireless communication unit is electrically connected to the second controller, and is used to wirelessly connect to the user terminal to output the changed length of the wire pulling line; the control unit includes a switch or a switch and an indicator light, the switch is arranged on the second PCB board, and is used to adjust the on and off of the power supply, and the indicator light is arranged on the second PCB board, and is used to indicate the on and off of the power supply.

[0106] The battery is a lithium battery, and the cable includes four wires, two power wires and two signal wires. One of the signal wires is used to transmit the data collected by the Hall sensor.

[0107] The second controller sends the data acquired by the data acquisition module to the computing end.

[0108] The number of the first interface and the second interface is set according to the demand. When the control module is located in the wire draw box, in order to save space, the first PCB board and the second PCB board can be the same PCB board, and the first interface and the second interface can be set to be one, and the first interface and the second interface are electrically connected through a cable.

[0109] The wireless communication unit may use a module supporting wireless communication such as Bluetooth, or a 3G / 4G wireless communication module, or a 5G wireless communication module. In this embodiment, a Bluetooth module is used.

[0114] If the control module is located in the wire drawing box, two sets of wire drawing gauges are required, namely, the upper wire drawing gauge and the lower wire drawing gauge, which are arranged on the bra body in a relative manner. The Hall sensor of the data acquisition module in each wire drawing gauge collects the NS magnetic pole signal change of the outer diameter elevation of the magnetic ring, and transmits the above data to the calculation end through the control module. At the calculation end, the corresponding chest circumference dimension is calculated according to the changes in the NS magnetic pole information obtained and the length of the ribbon.

[0115] If no ribbon is set in the pull wire measuring tool, the pull wire box body is set on the bra body. For the pull wire with free ends at both ends, the two free ends are respectively connected to the two sides of the zipper. For the pull wire with one free end, the free end of the pull wire is connected to one side of the zipper, and the pull wire box body is connected to the other side of the zipper.
