Description
[0001] Bra guide element
[0002] The invention relates to a bra with cups and a breast band as well as a guide element which is suitable and intended to receive a tube, preferably of a breast feeding set.
[0003] State of the art
[0004] Nursing bras are well known. These bras typically feature a fold-out cup that allows an infant to easily reach the nipple of the wearer. At the same time, the wearer's breast is held in place. A breast feeding set can be used to supplement the infant's nutrition during breastfeeding. A feeding container is attached to the breast, and a tube is attached to it, positioned in close proximity to the nipple. In the simplest case, the tube is attached to the breast skin using an adhesive bandage.
[0005] Publication EP 2 877 047 B1 discloses a nursing bra with a breast band and foldable cups. The front part comprises a first flexible tube and a second flexible tube, which serve to support the breast. The first tube extends along a portion of the underside edge of the first cup, and the second tube extends along at least a portion of the underside edge of the second cup. The tubes are sewn to the breast band.
[0006] This bra has the disadvantage that it lacks elements for guiding a tube for supplementary feeding. Therefore, the object of the present invention is to provide a bra that overcomes these disadvantages.
[0007] The object is achieved by means of the bra with cups and a breast band according to claim 1. Further advantageous embodiments are described in the subclaims.
[0008] The bra according to the invention has a cup and a breast band. According to the invention, the bra has a guide element that is intended and suitable for receiving a tube. By means of the guide element, the tube of a breast feeding set is received, secured, and guided such that one end of the tube is arranged directly on or in the immediate vicinity of the nipple. Manual guidance and securing of the tube is therefore no longer necessary. The wearer of the bra according to the invention can use both hands to hold the infant being breastfed. The use of adhesive strips on the skin of the female breast, which is often problematic for the skin, is also eliminated. The guide element is advantageously designed in such a way that it is skin-friendly and not visible from the outside.
[0009] A guide element within the meaning of this patent specification is an element designed and suitable for inserting and removing a hose from the guide element. Preferably, the guide element has two openings, with the hose being insertable into the first opening and removable from the second. The guide element can be designed as an eyelet or a loop. The guide element can also be designed as a clamping device for securing the hose. Other designs are possible.
[0010] The tubes for supplementary feeding of infants have a diameter of less than 5 mm, often approximately 1 mm. The tube end must be positioned near the nipple for supplementary feeding. The guide element is suitable for receiving, holding, and / or positioning tubes with a diameter of less than 5 mm, preferably less than 3 mm, and particularly preferably less than 2 mm. Preferably, the holder can accommodate tubes with a maximum diameter of 2 cm, preferably a maximum diameter of 1 cm, and particularly preferably a maximum diameter of 0.3 cm. In a particular embodiment, the holder can suitably accommodate tubes with a maximum diameter of 1 mm.
[0011] In a further development of the invention, the guide element is firmly connected to the bra. In an optional embodiment, for example, loops are sewn to the bra. In another embodiment, the guide element is designed as a yarn that is sewn to the bra on two sides. In this embodiment, the tube is guided underneath the yarn.
[0012] In a further development of the invention, the guide element according to the invention is arranged on the inside of the cup. This ensures that the end of the tube held by the guide element can be arranged on the inside of the cup in close proximity to the nipple.
[0013] In a further development of the invention, the guide element has an opening which is suitable and intended for removing a tube arranged in the guide element of the bra through an opening of the guide element.
[0014] In a further development of the invention, a guide element is arranged on the side panel, the upper breast band, and / or the lower breast band of the bra. The guide element is preferably arranged on the reinforced borders. This ensures that the tube of a breast feeding set is received and guided in such a way that the end of the tube can be positioned directly on or in the immediate vicinity of the nipple.
[0015] In a further embodiment of the invention, several guide elements are arranged on the side panel, on the upper and / or lower breast band of the bra. Preferably, a plurality of guide elements are arranged on the reinforced borders of the bra according to the invention. The tube of the breast feeding set can therefore be arranged, secured, and guided by means of a plurality of guide elements. The tube and the breast feeding set can therefore be individually adjusted.
[0016] In an advantageous embodiment of the invention, the guide elements are arranged on the side panel and the upper breast band, on the side panel and the lower breast band, or on the lower and upper breast band. This multiple arrangement of the guide elements allows the tube of the breast feeding set to be guided in different ways such that one end of the tube is positioned at or in the immediate vicinity of the nipple, thus enabling supplementary feeding of the infant.
[0017] In a further embodiment of the invention, the cup has an opening for the nipple. This opening exposes the nipple of the female breast in such a way that a nursing infant can reach the nipple. The bra according to the invention can therefore also be used as a conventional nursing bra, as is known from the prior art.
[0018] In a further development of the invention, the cup opening can be opened and / or closed with a folding nursing access panel. The nursing access panel is designed as a fabric cover and exposes the nipple opening of the female breast for a nursing infant or closes the opening when not in use. The bra according to the invention can therefore be used like a conventional nursing bra.
[0019] In a further embodiment of the invention, the nursing access for opening the bra can be attached and / or detached from the strap by a fastening element. The fastening element is, for example, a clip connection, a clamp connection, a Velcro connection, or a clip connection comprising a hook and eye. The fastening element is so easy to operate that the wearer of the bra according to the invention can comfortably open and close the nursing access with one hand. The bra fastening elements corresponding to the strap fastening element are arranged on the upper, side, and / or lower breast band.
[0020] In a further advantageous embodiment of the invention, the closure element comprises a first closure element on the strap and a second closure element corresponding to the first closure element on the fabric cover of the nursing access of the bra. The closure elements, e.g., a clip connection with a hook and eyelet, function according to the lock-and-key principle, with the corresponding closure elements being arranged on the strap of the bra and on the fabric cover of the nursing access.
[0021] In an advantageous embodiment of the invention, the guide element is formed from loops or clips or a clamping device that is attached to the bra. The loops or clips or a clamping device are dimensioned such that a tube of a breast feeding set can be arranged in the loops or clips or a clamping device. The loops or clips or a clamping device are spaced apart from one another such that the tube is both arranged on the bra and guided such that one end of the tube is positioned directly on or in the immediate vicinity of the nipple.
[0022] In a further development of the invention, the loop is integrated into a seam of the bra. The seam is located, in particular, at the edge of a breast band of the bra. The seam reinforces the edge of the breast band or forms a hem at the edge of the breast band.
[0023] In a further embodiment of the invention, a tube is guided through the loops. The loops are sized such that a tube of a breast feeding set can be arranged in the loops. The loops are arranged at such a distance from one another that the tube is both arranged on the bra and guided such that one end of the tube is arranged directly on or in the immediate vicinity of the nipple. In an advantageous embodiment of the invention, the guide element is formed by a belt system. The belt system can be detachably fastened to the bra according to the invention and has the guide element with which a tube of a breast feeding set is guided such that one end of the tube is arranged directly on or in the immediate vicinity of the nipple. Manual guidance and / or fixation of the tube is therefore not necessary.The wearer of the bra according to the invention can use both hands to hold the infant she is breastfeeding. It also eliminates the need for the often problematic use of adhesive strips on the skin of the female breast.
[0024] In a further embodiment of the invention, a strap of the harness system has an adjustment element suitable for adjusting the length of the strap. The strap, and thus the entire harness system, can be flexibly adjusted to the individual breast size of the wearer of the harness system using the adjustment element.
[0025] In a further embodiment of the invention, the belt system comprises several belts. The guide element is arranged on the belt system's straps, with which a tube of a breast feeding set is guided such that one end of the tube is positioned directly at or in the immediate vicinity of the nipple. The tube of the breast feeding set can be positioned, secured, and guided using a plurality of guide elements. The tube and the breast feeding set can therefore be individually adjusted and stored.
[0026] In a further development of the invention, a first belt of the belt system is connected to a second belt of the belt system.
[0027] In a further embodiment of the invention, the first strap of the harness system is guided through a loop formed by the second strap of the harness system. The first strap is thus movably guided in the loop of the second strap. The harness system can therefore be flexibly adjusted to the chest of the wearer.
[0028] In a further embodiment of the invention, a belt connecting element is arranged at one end of a strap of the belt system, which is intended and suitable for attaching the belt system to a bra. In particular, the belt system can be releasably attached to a bra by means of the belt connecting element. When not in use, the belt system can therefore be removed from the bra, allowing the bra according to the invention to be worn like a conventional bra.
[0029] In a further embodiment of the invention, a bra connecting element corresponding to the strap connecting element is arranged on the bra. The strap connecting element and the bra connecting element, e.g., a clip connection with a hook and eye, function according to the lock-and-key principle, with the corresponding connecting elements being arranged on the bra and the strap system, respectively.
[0030] In a further development of the invention, the strap connecting element is designed as a clip. A clip connection is easy to manually establish and release and simultaneously ensures a secure connection between the bra and the strap system.
[0031] In a further embodiment of the invention, the belt system has a guide element that is intended and suitable for receiving a tube. By means of the guide element, the tube of a breast feeding set is received, secured, and guided such that one end of the tube is arranged directly on or in the immediate vicinity of the nipple. Manual guidance and / or securing of the tube is therefore not necessary; the wearer of the bra according to the invention can use both hands to hold the infant being breastfed. Likewise, the use of adhesive strips on the skin of the female breast, which is often problematic for the skin, is eliminated. This object is achieved by means of a bra with cups and a breast band according to claim 1. Further advantageous embodiments are described in the subclaims.
[0032] In a further development of the invention, the guide element is formed by one or more straps of the harness system itself. The tube is secured in position between the strap and the breast, thus guiding the end of the tube near the nipple.
