Description

sports bra

[0001] The present invention relates to a sports bra, and more specifically, to a sports bra that provides comfort when worn and is adjustable to fit the body size.

[0002] Sports bras are worn on the chest to cover and protect the area, while using materials with higher elasticity than conventional bras to provide firm support, maintaining the position and shape of the breasts during various movements and assisting the wearer's actions.

[0003] However, the sizing system for sports bras does not exactly match that of regular bras, so even with the same cup size, the fit can vary depending on bust circumference or body shape. As a result, even if a specific size is selected, it often does not fit snugly, leading to discomfort during exercise.

[0004] Therefore, there is a problem in that selecting an inaccurate size can cause discomfort and potentially hinder freedom of movement.

[0005] In addition, since most sports bras are wire-free, they may not provide sufficient support for larger breasts, which can cause breast pain or fatigue. Furthermore, insufficient support can lead to excessive movement of the breasts during exercise, which can cause discomfort.

[0006] Some sports bras provide tight support to alleviate discomfort, which can irritate the skin; consequently, strong compression can restrict muscles and hinder blood circulation.

[0007] Therefore, to resolve discomfort during exercise, a sports bra that fits the individual's body condition is necessary.

[0008] The technology forming the background of the present invention is disclosed in Korean Registered Patent Publication 10-1827190 (February 1, 2018).

[0009] The above registered patent publication relates to an exercise bra and provides a bra comprising a front portion configured to cover the wearer's chest, a back portion connected to the front portion to surround the wearer's torso, and a torso band attached along the bottom edge of the front portion and the back portion.

[0010] Here, the bra comprises a supporting fabric layer disposed between an inner layer and an outer layer forming the front portion of the bra, and the supporting fabric layer is configured to include at least one first portion located at the upper part of the front portion and a pair of second portions disposed to correspond to the sides of the wearer's chest.

[0011] However, in the aforementioned registered patent publication, the front of the bra cannot be opened or closed, so it cannot respond sensitively to breast size, and furthermore, only a simple elastic band is installed around the torso.

[0012] Because this structure cannot accommodate various body sizes, it fails to respond to the movements of women exercising, inevitably causing discomfort.

[0013] The present invention aims to provide a sports bra that offers stable support and comfort for breasts that move during exercise, tailored to the user's different physical conditions. This technical objective includes a design for stable support of moving breasts, high breathability and elasticity, and prevention of shoulder strap slippage.

[0014] Meanwhile, the technical problem that the present invention aims to solve is not limited to the technical problem mentioned above, and various technical problems may be included within the scope obvious to a person skilled in the art from the contents described below.

[0015] A sports bra according to the present invention may include a sports bra made of an elastic material having a shape that wraps around the torso of a wearer, a front portion that wraps around the wearer's chest, a rear portion that extends from the front portion to the rear of the torso and has a shape that branches into an upper and lower portion based on the front portion, wherein the branched end is connected to the front portion so as to adjust the length, and a band portion that has a shape that wraps around the torso and is connected from the lower portion of the front portion to the lower portion of the rear portion.

[0016] In addition, the band portion is made of an elastic material and extends downward from the front portion and the rear portion, and both ends can be detachably connected at the rear portion of the body to wrap around the circumference of the body along the rear portion.

[0017] And the above rear portion connects the upper part of the band portion and the upper part of the front portion, and can be joined so as to be adjustable in length at the upper part of the front portion.

[0018] In addition, the rear portion includes a band-shaped length adjustment member having elasticity at the top, and the length adjustment member has one end connected to the rear portion and the other end connected to the upper part of the front portion and attached to the outer surface of the length adjustment member, thereby allowing the length between the rear portion and the front portion to be adjusted.

[0019] In addition, the front portion may include a pad member shaped to wrap around the chest on the inner side and an opening / closing member provided at the center of the front portion to adjust the spacing of the pad member so that the spacing becomes wider or narrower.

[0020] According to the present invention as described above, the effects described below can be obtained. However, the effects obtainable through the present invention are not limited thereto.

[0021] The present invention allows the length of the shoulder straps capable of supporting the chest to be adjusted on both sides, thereby enabling length adjustment to fit the wearer's body according to chest shape and size, and has the effect of stably supporting the body.

[0022] In addition, the present invention has the effect of providing comfort by allowing the lower band to be worn to fit the user's torso via Velcro.

[0023] In addition, the present invention is provided with an incision at the front end, which not only allows the degree of opening to be adjusted so as not to compress the chest, but also has the effect of preventing sweat from accumulating on the chest during exercise and allowing air to pass through.

[0024] In addition, it has the effect of improving support and breathability by using a fabric that combines a fiber structure with excellent elasticity and a material that does not easily deform due to its outstanding resilience in appropriate proportions.

[0025] In addition, it has the effect of providing consistent support by adapting to changes in breast size caused by body movements and hormonal changes during a woman's menstrual cycle.

[0026] In addition, the configuration of the opening / closing member and the pad member allows for independent support of both breasts by separating the cups, and has the effect of controlling vertical and horizontal movements in response to different sizes.

[0027] The technical problems to be solved by the present invention are not limited to the above technical problems, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0036] A preferred embodiment according to the present invention will be described in detail below with reference to the attached drawings.

[0037] The advantages and features of the present invention and the method for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0038] However, the present invention is not limited by the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0039] In addition, in describing the present invention, if it is determined that related known technologies, etc., may obscure the essence of the present invention, a detailed explanation thereof will be omitted.

[0040] FIG. 1 is a drawing showing the overall shape of a sports bra according to an embodiment of the present invention, FIG. 2 is a drawing for explaining the front part (100) of a sports bra according to an embodiment of the present invention, FIG. 3 is a drawing for explaining the rear part (300) of a sports bra according to an embodiment of the present invention, FIG. 4 is a drawing for explaining the side of a sports bra according to an embodiment of the present invention, and FIG. 5 is a drawing for explaining the first Velcro (350) of a sports bra according to an embodiment of the present invention.

[0041] As described above, the present invention is a sports bra designed to facilitate a woman's physical activity and can be formed from an elastic material having a shape that wraps around the wearer's torso.

[0042] The configuration for this may largely include a front part (100), a rear part (300), and a band part (500).

[0043] First, the front portion (100) is formed to wrap around the wearer's chest, and the rear portion (300) extends from the front portion (100) to the rear of the torso and may have a shape that branches into an upper and lower section based on the front portion (100).

[0044] And the rear portion (300) can be joined so that the branched end is connected to the front portion (100) in length.

[0045] The next band portion (500) is connected from the lower part of the front portion (100) to the lower part of the rear portion (300) and has a shape that wraps around the body.

[0046] Specifically, the band portion (500) is made of an elastic material and extends downward from the front portion (100) and the rear portion (300), and both ends can be detachably connected at the rear of the body to wrap around the circumference of the body along the rear portion (300).

[0047] In this way, both ends of the band (500) are detachable, allowing for independent support of both breasts, and enabling smooth support even if the sizes of the breasts are different.

[0048] The above band portion (500) can improve support and breathability by mixing nylon fibers with excellent elasticity and spandex fibers that do not easily deform in a predetermined ratio.

[0049] Specifically, the nylon and spandex blend reduces material roughness due to the inherent characteristics of the materials, and the combination of nylon and spandex provides high elasticity and strength simultaneously, thereby enhancing support performance.

[0050] In the present invention, the nylon and spandex materials can be applied not only to the band portion (500) but also to the pad member (120) inside the front portion (100), so they can be used in the part that comes into contact with the chest, and can prevent skin chafing even when the chest shakes.

[0051] The front part (100), the rear part (300), and the band part (500) of the sports bra of the present invention may be integrally formed by a fixing method such as sewing or welding.

[0052] The band portion (500) of the present invention will be described in detail.

[0053] The band portion (500) is formed long with a predetermined width and has elasticity, so it can be stretched in the length direction and width direction.

[0054] And the band portion (500) extends downward from the front portion (100), and can be formed to be long enough to extend in the width direction of the band portion (500) and wrap around the wearer's torso.

[0055] In addition, the band portion (500) has a structure in which the length is adjustable at the end, and since the band portion (500) is formed at the lower part of the front portion (100), the length of the front portion (100) can also be adjusted.

[0056] Here, the length adjustment of the band portion (500) may be a Velcro type, and this will be explained in detail through Fig. 6.

[0057] Meanwhile, the front portion (100) wraps around the wearer's chest, and a pair of pad members (120) that adhere to the chest are formed inside, and a center is formed between the pad members (120) so as to be cut, and an opening / closing member (140) is provided in the cut portion to adjust the gap between the pair of pad members (120).

[0058] The configuration of the pad member (120) and the opening / closing member (140) described above allows for independent support of the breasts by separating and wrapping both breasts with separate cups, and can respond to vertical and horizontal movements during exercise.

[0059] In addition, when the two breasts are different sizes, the band (500) can be adjusted so that they can be supported comfortably and independently.

[0060] An opening / closing member (140) according to one embodiment of the present invention may be provided in a zipper manner, and the opening / closing member (140) may be provided to be opened from the top.

[0061] In addition, the front portion (100) according to the present invention may have a zipper covering member (180) formed so as to cover the top and bottom of the opening / closing member (140).

[0062] The zipper cover member (180) is provided in a shape that wraps around the opening / closing member (140), so that it can at least cover the slider (illustrated but not labeled) of the opening / closing member (140).

[0063] This prevents the front part (100) from opening due to the slider being caught by an external object during active movement while wearing the sports bra of the present invention, and also prevents the slider from interfering with the wearer's movement because the front end is fixed to the two lines of the zipper and the rear end is a free end.

[0064] For example, when the wearer repeats a squat motion, the two hands may come together from the pelvis in front of the chest.

[0065] At this time, the rear end of the slider may come into contact with the wearer's hand by performing a sitting and standing motion. To prevent this, the front part (100) may include a zipper cover member (180).

[0066] Looking at the drawing, it can be seen that in FIG. 2, the zipper cover member (180) has a triangular shape and is formed to cover a part of the top and bottom of the opening / closing member (140).

[0067] At this time, the degree to which the zipper covering member (180) covers the opening / closing member (140) may be such that only at least a part of the slider is exposed or the whole is hidden, and specifically, the rear end of the slider may be fixed.

[0068] Meanwhile, the rear portion (300) can be formed in an X shape on the wearer's back to allow for smooth movement of the wearer's arm.

[0069] The rear portion (300) being X-shaped may be formed to be exposed so that the part corresponding to the scapula or shoulder blade can move freely.

[0070] Specifically, the rear portion (300) can be formed with a racerback design to avoid sensitive areas around the shoulder blade.

[0071] Therefore, the rear portion (300) may have a shape that branches into an upper and a lower section.

[0072] The rear portion (300) may be characterized by connecting the upper portion of the band portion (500) and the upper portion of the front portion (100), and being joined so that the length is adjustable at the upper portion of the front portion (100).

[0073] Specifically, the rear portion (300) may include a band-shaped length adjustment member (340) having elasticity at the top.

[0074] The length adjustment member (340) is formed long and has a length and width, and one end is connected to the rear portion (300), and the other end is connected to the upper part of the front portion (100) so that the length between the rear portion (300) and the front portion (100) can be adjusted by being attached to the outer surface of the length adjustment member (340).

[0075] In this embodiment, the length adjustment member (340) is formed to include a first Velcro (350) of the Velcro type, and the first Velcro (350) is formed on the same surface so that the end can be attached to the length adjustment member (340) by hooking a part of the front portion (100).

[0076] The length adjustment member (340) can adjust the size and pressure of the sports bra according to the present invention in response to minute changes in the breast size of the same user according to changes in the wearer's breasts, that is, hormonal changes such as menstruation.

[0077] Specifically, the first Velcro (350) has both a hook and a hook formed on the same surface, and either a hook or a hook is formed at the end, so that after the end is connected to the front part (100), it can be fixed in a form that is attached by folding toward the hook or hook formed at the end and the other.

[0078] To this end, a first ring (190) may be formed in the portion where the length adjustment member (340) is connected at the front portion (100).

[0079] The first ring (190) may have two holes formed therein, and one hole may be attached to the front part (100) by the inner and outer layers of the front part (100) wrapping around a part of the hole of the first ring (190), and the length adjustment member (340) may be connected to the front part (100) by being inserted into and wrapping around another hole of the first ring (190).

[0080] Here, the length adjustment member (340) may have a structure that folds upward so that the first Velcro (350) does not come into contact with the wearer's shoulder and is exposed to the outside.

[0081] This prevents the wearer from getting a cut on their skin by the first Velcro (350).

[0082] Next, let's take a closer look at the rear section (300) through Fig. 5.

[0083] As described above, the rear portion (300) is formed in an overall X shape and may include a central member (320) extending from the side of the front portion (100), a length adjustment member (340) formed on the upper part of the central member (320), and a lower connecting member (360) extending to the lower part of the central member (320).

[0084] As the length adjustment member (340) has been explained previously, the details regarding how the length adjustment member (340) is connected to the front part (100) will be omitted.

[0085] The lower part of the central member (320) can continue to branch downward on both sides along a virtual vertical line (not shown).

[0086] And the branched part may be a lower connecting member (360).

[0087] The lower connecting member (360) is formed integrally with both ends connected to the upper end of the band portion (500), and can be described as being between the side of the front portion (100) and the central member (320).

[0088] The rear portion (300) is made of a material that has elasticity, so it can be stretched in response to the wearer's movements, and the lower connecting member (360) is formed with a predetermined width to wrap around the wearer's side and back, and can be made of a material that absorbs sweat and evaporates moisture into the air.

[0089] Meanwhile, the band portion (500), which is formed integrally with the front portion (100) and the lower connecting member (360), has a second Velcro (520) and a second ring (510) formed along a portion along the longitudinal direction so that the total length of the band portion (500) can be adjusted.

[0090] The band portion (500) has its end inserted into the second ring (510) in the same way as the length adjustment member (340) described above, and the inserted end can be folded and adhered towards the center of the band portion (500).

[0091] This is illustrated in Fig. 6.

[0092] FIG. 6 is a drawing for explaining the rear portion (300) and the band portion (500) of a sports bra according to one embodiment of the present invention.

[0093] As shown in the illustration, the upper part of the band portion (500) is formed integrally with the front portion (100) and the lower connecting member (360), and a second Velcro (520) and a second ring (510) are formed at the bottom of the empty hole (illustrated but not having a reference numeral) between the branching ends of the lower connecting member (360).

[0094] The second ring (510) has two holes formed in the same way as the first ring (190), so that one end of the band portion (500) is inserted into and wrapped around one of the holes, and the second ring (510) is attached to the end of the band portion (500), and the other end of the band portion (500) is inserted into the other hole of the second ring (510) and can be folded toward the center of the band portion (500) to wrap around the second ring (510) and adhere.

[0095] The band portion (500) may also have a second Velcro (520) formed on the other side exposed to the outside, rather than on the side that comes into contact with the wearer's skin.

[0096] In this way, the distance between the shoulder and the front part (100) can be adjusted to minimize horizontal movement of the chest during high-intensity exercise through the band part (500) which can be adjusted in length using a Velcro method, and the pressure on the shoulder can be distributed in a way that wraps around the torso with the weight of the chest, thereby minimizing the burden during exercise.

[0097] In addition, the Velcro system allows for fine adjustments to the chest circumference, making it effective not only for maintaining stability during high-intensity exercise but also for immediately responding to weight gain or loss or changes in volume during workouts.

[0098] Meanwhile, a liner member (380) may be further included inside the central member (320) and the lower connecting member (360) in the rear portion (300).

[0099] I will explain by referring to the drawings.

[0100] FIG. 7 is a drawing for explaining a liner member (380) in a sports bra according to one embodiment of the present invention.

[0101] First, the liner member (380) is formed long from an elastic material and can be fixed to the inner edge of the central member (320) and the lower connecting member (360).

[0102] Here, the central member (320) and the lower connecting member (360) are composed of an inner layer and an outer layer, and the liner member (380) is placed between the inner layer and the outer layer to maintain the overall shape of the central member (320) and the lower connecting member (360). Since the area of ​​the central member (320) and the lower connecting member (360) is large, they may be formed with an inner layer, an outer layer, and a liner member (380) to prevent the fiber from tearing during the stretching process.

[0103] Meanwhile, the opening / closing member (140) described above may be provided in the form of a zipper and may further include a locking member (160) inside.

[0104] I will explain this in detail using drawings.

[0105] FIG. 8 is a drawing for explaining an opening / closing member (140) in a sports bra according to one embodiment of the present invention.

[0106] As described, when the opening / closing member (140) is open, the locking member (160) can prevent the front portion (100) from being fully opened.

[0107] The locking member (160) may be provided to prevent the front part (100) from being completely separated even when the opening / closing member (140) is fully open.

[0108] The locking member (160) for this purpose can be provided in the form of a hook (162) and a loop (164).

[0109] Therefore, even if the above slider is moved downward and the center of the front part (100), i.e., the pad member (120) is separated, a locking member (160) is provided to maintain a predetermined separation distance.

[0110] This allows the locking member (160) to prevent the full opening of the front part (100) even when the opening / closing member (140) is opened because the slider is unintentionally caught by the external environment, thereby preventing an accident.

[0111] Additionally, according to a modified embodiment of the present invention, an opening (not shown) is formed on the outer side of the front portion (100), and a Velcro-type entrance (not shown) that closes the opening is provided so that an implant (not shown) can be inserted into the front portion (100).

[0112] Alternatively, a towel or a simple object may be inserted into the opening.

[0113] In addition, the first Velcro (350) and the second Velcro (520) according to the present invention may include a fixing clip (not shown) that wraps around the side portion where the hook and the hook protrusion are attached in order to prevent the hook and the hook protrusion of the Velcro from becoming separated due to violent movements and external environmental factors.

[0114] The above fixing clip will be explained in detail.

[0115] First, let us describe the exposed surface (not shown in the drawing) on ​​which the hook or the hook projection is formed in the first Velcro (350) of the length adjustment member (340) or the second Velcro (520) of the band part (500), and the contact surface (not shown in the drawing) which is opposite to the exposed surface and comes into contact with the skin.

[0116] For example, in the case of the length adjustment member (340), the fixing clip is configured such that one end of two members is axially connected and the end extending away from the axis is open, allowing for fitting in the width direction of the length adjustment member (340).

[0117] Here, a lower member fixed to the contact surface of the length adjustment member (340) and one end of which is axially connected to the lower member, and the other end formed to be away from the lower member with respect to the axis, can be formed to wrap around the first Velcro (350) from the side.

[0118] In addition, a plurality of protrusions are formed on the upper surface of the lower member and a plurality of protrusions are formed on the lower surface of the upper member, wherein the protrusions of the lower member and the protrusions of the upper member are arranged to be offset from each other, and the other ends of the upper member and the lower member are configured to be snap-fitted so as to be joined with the first Velcro (350) in between.

[0119] This prevents the first Velcro (350) from being unintentionally separated due to external environmental factors.

[0120] Although specific embodiments of the sports bra according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0121] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.

[0122] That is, the aforementioned embodiments should be understood as exemplary in all respects and not limiting, and the scope of the invention is defined by the claims set forth below rather than by the detailed description, and all modifications or variations derived from the meaning and scope of the claims and equivalent concepts thereof should be interpreted as being included within the scope of the invention.
