Abstract
Description
[Technical Field]
[0001] The present invention relates to a chest attachment device that is attached to the chest. [Background technology]
[0002] There are known devices that are worn around the chest. For example, Patent Document 1 discloses a bust correction device that includes a bust correction plate made of a hard plate material that is held by a piece of cloth located under the armpits or in the vicinity thereof and presses against the skin, flesh, fat, etc. on the sides of the body, generating a correction force that narrows the distance between the breasts. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-241904 Summary of the Invention [Problem to be solved by the invention]
[0004] The inventors have studied wearing devices that are worn around the human rib cage and have come to the following realization. The device in Patent Document 1 uses a hard correction plate to generate a corrective force that narrows the distance between the breasts, correcting the breasts by expanding them overall from the base and by protruding them forward. In other words, this device appears to be a shape-fitting undergarment designed to improve the aesthetic appearance of the chest. When this device is worn, the hard member is pressed against the chest, and the wearer experiences an uncomfortable feeling from the hard member and a strong pressure sensation while wearing it, which increases discomfort over time.
[0005] Furthermore, since this type of accessory is frequently washed, the hard plate must be removed when washing and then reattached when using, which is time-consuming and cumbersome. Furthermore, when the hard plate is removed and reattached, the mounting position of the hard plate may shift from its intended position, preventing it from performing its intended function. In particular, the hard plate correction plate generates a corrective force that narrows the breast spacing, which increases the burden on breathing and makes breathing difficult.
[0006] SUMMARY OF THE INVENTION The object of the present invention is to solve the above problems and to provide a chest harness that can make breathing easier while avoiding the discomfort caused by hard boards. [Means for solving the problem]
[0007] In order to solve the above problems, one embodiment of the present invention provides a chest harness that is worn around the chest surrounding the rib cage and includes a front section having a pair of cup sections for covering the chest fullness, a pair of overlapping members that are made of a flexible fabric with less stretch than the front section and have enough stretch to abut the area from the side edges of the chest fullness to the vicinity of the mid-axillary line when worn and are attached and fixed to the front section, a rear section that includes a portion that is worn on the back, and a pair of stretch adjustment members that are provided between the overlapping members and the rear section and have higher stretchability than the front and rear sections. The overlapping members are generally L-shaped, with a first section that extends vertically along the side edges of the cup sections and a second section that projects from the first section to the lower edge of the cup sections. At the same time, it is made of a thicker material than the front part and is positioned anterior to the mid-axillary line. .
[0008] Any combination of the above components or mutual substitution of the components or expressions of the present invention between methods, devices, systems, etc. are also valid aspects of the present invention. [Effects of the Invention]
[0009] According to the present invention, it is possible to provide a chest harness that can make breathing easier while avoiding the discomfort caused by hard boards. [Brief explanation of the drawings]
[0010] [Figure 1] FIG. 2 is a diagram showing the chest attachment device of the embodiment as viewed from the inside. [Figure 2] FIG. 2 is a diagram showing the front part of FIG. 1. [Figure 3] 2 is a diagram showing an overlapping member and an expansion / contraction adjustment part of FIG. 1. FIG. [Figure 4] FIG. 2 is a view showing the rear part of FIG. [Figure 5] FIG. 2 is a diagram showing an outer fabric part of the chest harness of FIG. 1. [Figure 6] FIG. 2 is a diagram showing an inner fabric part of the chest harness of FIG. 1. [Figure 7] 2A and 2B are diagrams showing the outline of the thorax before and after wearing the chest wearing device of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION
[0011] The inventors have found that when wearing the bust correction device described in Patent Document 1 (hereinafter simply referred to as the "bust correction device"), breathing tends to become shallower than before wearing it. That is, when the bust correction device is worn around the chest, the hard correction plate applies a correction force (hereinafter simply referred to as the "correction force") that narrows the gap between the bulges of the chest (also called breasts), preventing the expansion of the thorax. In this case, the corrective force applied to the thorax places a burden on breathing, and it has been found that breathing becomes shallower unconsciously, even if it does not feel painful.
[0012] The inventors have found that for a chest harness that surrounds the thorax at the front and rear, by combining an overlapping member made of flexible fabric that is less stretchy than the front portion with an expansion / contraction adjustment section that is more stretchy than the front and rear portions, the discomfort caused by hard board materials can be avoided and breathing can be made easier.
[0013] The function of the present invention will be explained with reference to Figure 7. Figure 7 is a top view diagram showing the outline of the thorax before and after wearing the chest harness. In this diagram, the outline of the outline before wearing is shown by a dashed line, and the outline of the outline when wearing is shown by a solid line. In this diagram, a gap is drawn between the chest harness and the thorax for ease of understanding, but when wearing the chest harness, the thorax contacts the thorax. Before wearing the chest harness, the cross section of the thorax is a slightly oval that is wide from side to side. By suppressing lateral expansion with the overlapping member and facilitating front-to-back expansion with the expansion adjustment unit, the perimeter of the thorax decreases and the thorax expands front to back, changing from an oval to a more circular shape. As a result, the thorax becomes more cylindrical, increasing the volume of the lungs and reducing resistance in the airways and alveoli, which is thought to facilitate breathing.
[0014] Hereinafter, a chest harness of the present invention in which an expansion / contraction adjustment part is combined with an overlapping member will be described with reference to embodiments, but the present invention is not limited or restricted to the following examples.
[0015] The present invention will be described below based on preferred embodiments with reference to the drawings. In the embodiments and modifications, identical or equivalent components and members are designated by the same reference numerals, and redundant explanations will be omitted where appropriate. The dimensions of the members in the drawings are enlarged or reduced as appropriate to facilitate understanding. Some members that are not important for explaining the embodiments will be omitted from the drawings.
[0016] Furthermore, terms including ordinal numbers such as first and second are used to describe various components, but these terms are used only to distinguish one component from another and do not limit the components.
[0017] In the following explanation, "parallel" and "perpendicular" do not only mean perfectly parallel or perpendicular, but also include deviations from parallel or perpendicular within a margin of error. Also, "substantially" means roughly the same.
[0018] [Embodiment] The configuration of a chest attachment device 100 according to an embodiment of the present invention will be described below with reference to Figs. 1 to 4. Fig. 1 is a diagram showing the chest attachment device 100 as seen from the inside. Fig. 2 is a diagram showing the front part as seen from the inside. Fig. 3 is a diagram showing the overlapping member and the expansion / contraction adjustment part as seen from the inside. Fig. 4 is a diagram showing the rear part as seen from the inside. The chest attachment device 100 is attached around the chest, surrounding the rib cage. The chest attachment device 100 according to the embodiment is a attachment that can be worn on the chest by both men and women. The chest attachment device 100 may be worn directly on the body like underwear, or may be worn over underwear such as a bra or T-shirt.
[0019] Hereinafter, when the chest mounting device 100 is worn on an upright body, the direction corresponding to the body's height will be referred to as the up-down direction, the direction corresponding to the left and right of the body will be referred to as the left-right direction, the direction corresponding to the front and back of the body will be referred to as the front-back direction, and the circumferential direction surrounding the body will be referred to as the chest circumferential direction. Also, the side of the chest mounting device 100 facing the body will be referred to as the inside, and the opposite side will be referred to as the outside. Also, the side relatively closest to the body when worn will be referred to as the skin side. These directional notations do not limit the posture in which the chest mounting device 100 is used, and the chest mounting device 100 can be used in any posture as needed.
[0020] The chest harness 100 of the embodiment is a chest harness worn around the chest surrounding the thorax, and includes a front section 2, a pair of overlapping members 1, a pair of expansion and contraction adjustment sections 4, a rear section 5, a pair of shoulder strap sections 34, and a hook section 37. In the embodiment, the hook section 37 is a rear hook type in which the rear section 5 is provided with the hook section 37, but is not limited to this. The chest harness 100 may also be a front hook type or a hookless type.
[0021] The front section 2 has a pair of cups 32 for covering the bust. Soft padding may be incorporated into the cups 32. The cups 32 may be generally circular when viewed from the inside, bulging forward toward the center, or may be flat. The front section 2 has a generally rectangular band-shaped main body 24 that is longer from side to side than from top to bottom, and an arc-shaped protrusion 26 that protrudes upward from the portion of the band-shaped main body 24 that corresponds to the cups 32. The shoulder straps 34 extend upward from the arc-shaped protrusion 26 and are connected to the rear section 5. The front section 2 can be made of a fabric material with a predetermined stretchability.
[0022] The overlapping member 1 is made of a flexible fabric with lower stretchability than the front portion 2. The fabric may be woven or nonwoven. Stretchability is an index that relatively indicates the degree of stretch rate, which is the ratio of elastic deformation to tensile load. A relatively small stretch rate is considered low stretchability, and a relatively large stretch rate is considered high stretchability. In this specification, the stretchability of each member refers to the stretchability of the material of that member in the chest-around direction. For example, the stretch rate may be calculated by dividing the stretch width when a predetermined tensile load is applied by the sample width before stretching. The overlapping member 1 has enough stretchability to abut the area from the side edge of the chest fullness to the vicinity of the mid-axillary line M when worn. Therefore, the overlapping member 1 does not include a hard plate. In Figure 1, the straight line corresponding to the mid-axillary line M when worn is indicated by the symbol M.
[0023] In the embodiment, the superimposed member 1 is attached and fixed to the front section 2 without any seams. The superimposed member 1 may be partially sewn while attached to the front section 2. With this configuration, the stretchability of the area of the front section 2 to which the superimposed member 1 is attached is lower than when the superimposed member 1 is not present, and lower than the superimposed member 1 alone. The superimposed member 1 in the embodiment is formed from a material that is thicker than the front section 2. The ratio of the thickness of the superimposed member 1 to the thickness of the front section 2 is preferably 2 to 10 times, and more preferably 2 to 4 times.
[0024] The overlapping member 1 is generally L-shaped, with a first portion 11 extending vertically along the side edge of the cup portion 32 and a second portion 12 extending from the first portion 11 to the lower edge of the cup portion 32. The inner edge 14 of the overlapping member 1 on the cup portion 32 side is arc-shaped to fit the outer periphery of the cup portion 32. The first portion 11 reduces the stretchability of the portion of the front portion 2 immediately beside the bust, while the second portion 12 reduces the stretchability of the portion of the front portion 2 immediately below the bust.
[0025] In this embodiment, the vertical width L1 of the overlapping member 1 is greater than the horizontal width L2 of the overlapping member 1. The ratio of the vertical width L1 to the horizontal width L2 is preferably 1.1 to 5 times, and more preferably 1.5 to 3 times. The rear end of the overlapping member 1 may extend beyond the mid-axillary line M when worn, but the overlapping member 1 in this embodiment is positioned anterior to the mid-axillary line M without extending beyond the mid-axillary line M.
[0026] The rear portion 5 is a belt-shaped member including a portion that is attached to the back side. In this embodiment, the rear portion 5 is provided with a hook portion 37. The rear portion 5 can be connected to the left and right sides by the hook portion 37, or can be separated to the left and right sides. The rear portion 5 can be made of a cloth material with a predetermined stretchability. In this embodiment, the rear portion 5 is made of a material with the same stretchability as the front portion 2. The shoulder strap portions 34 extend upward from the rear portion 5 and are connected to the front portion 2.
[0027] The expansion adjustment part 4 is a strip-shaped member provided between the overlapping member 1 and the rear part 5. In this embodiment, the expansion adjustment part 4 connects the rear end of the front part 2 and the front end of the rear part 5. The expansion adjustment part 4 is made of a fabric material that is more stretchable (has a relatively high stretch rate) than the front part 2 and the rear part 5. In this embodiment, the vertical width L3 of the expansion adjustment part 4 is larger than the horizontal width L4 of the expansion adjustment part 4, and is preferably 2 to 4 times the horizontal width, and in this example is 2.6 times.
[0028] The layer structure of the chest harness 100 of this embodiment will be described with reference to Figures 5 and 6. The chest harness 100 of this embodiment has a layer structure in which an outer layer 6, an inner layer 7, and an overlapping member 1 are bonded together. Figure 5 is a diagram showing the outer layer 6 of the chest harness 100. Figure 6 is a diagram showing the inner layer 7 of the chest harness 100. The outer layer 6 includes an outer fabric portion 21 of the front section 2, an elasticity adjustment section 4, an outer fabric portion 51 of the rear section 5, and an outer fabric portion 35 of the shoulder straps 34. The inner layer 7 includes an inner fabric portion 22 of the front section 2, an inner fabric portion 52 of the rear section 5, and an outer fabric portion 36 of the shoulder straps 34. In other words, the front section 2 includes the outer fabric portion 21 and the inner fabric portion 22 bonded to the skin side of the outer fabric portion 21, and the overlapping member 1 is bonded to the skin side of the inner fabric portion 22. The rear portion 5 includes an outer fabric portion 51 and an inner fabric portion 52 .
[0029] The following describes the features of the chest harness 100 of this embodiment. The chest harness 100 is worn around the chest, surrounding the rib cage, and includes a front section 2 having a pair of cup sections 32 for covering the chest fullness, a pair of overlapping members 1 attached and fixed to the front section 2, and made of a flexible fabric with less stretch than the front section 2. The overlapping members 1 are stretchable enough to contact the region from the side edges of the chest fullness to the vicinity of the mid-axillary line M when worn, a rear section 5 including a portion worn on the back, and a pair of stretch adjustment members 4 provided between the overlapping members 1 and the rear section 5 and with greater stretchability than the front section 2 and rear section 5. The overlapping member 1 is generally L-shaped, with a first section 11 extending vertically along the side edges of the cup sections 32 and a second section 12 extending from the first section 11 to the lower edges of the cup sections 32.
[0030] With this configuration, the thoracic cage becomes more cylindrical by firmly supporting the periphery of the chest swelling with the less stretchy overlapping member 1 and suppressing left and right expansion, while the more stretchy expansion adjustment part 4 facilitates front and back expansion. As a result, the volume of the lungs increases, and resistance in the airways and alveoli decreases, making breathing easier.
[0031] Furthermore, with the chest harness 100, the hard members are not pressed against the chest when worn, eliminating the discomfort and oppressive feeling caused by the hard members. Furthermore, there is no need to take the time to remove the hard members when washing, making handling easier. Furthermore, the positional relationship between the overlapping member 1 and the expansion / contraction adjustment part 4 is stable, allowing the original functions to be fully exerted.
[0032] As an example, in the chest harness 100, the overlapping member 1 is formed of a material that is thicker than the front part 2. In this case, it is easy to reduce the stretchability of the overlapping member 1, and the desired stretchability can be easily achieved.
[0033] As an example, in the chest harness 100, the front part 2 includes an outer fabric part 21 and an inner fabric part 22 bonded to the skin side of the outer fabric part 21, with the overlapping member 1 bonded to the skin side of the inner fabric part 22. In this case, the chest harness 100 can be formed by bonding the layers together, which makes it easier to improve the positional accuracy of each part and also improves the connection strength compared to when connecting by sewing. Because the overlapping member 1 is layered on the skin side, the sense of support for the fullness of the chest can be improved.
[0034] As an example, in the chest harness 100, the expansion and contraction adjustment part 4 includes a part that extends in the front-to-rear direction when worn, and is formed integrally with the outer fabric part 21. In this case, the expansion and contraction adjustment part 4 and the outer fabric part 21 can be formed seamlessly and integrally, which reduces the effort required for connecting them and ensures sufficient strength. Furthermore, because the expansion and contraction adjustment part 4 extends in the front-to-rear direction, expansion and contraction in the front-to-rear direction is easy.
[0035] As an example, in the chest harness 100, the vertical width L1 of the overlapping member 1 is larger than the horizontal width L2 of the overlapping member 1. In this case, by increasing the vertical width L1, the expansion suppression range can be expanded in the vertical direction.
[0036] As an example, in the chest harness 100, the overlapping member 1 is disposed in front of the mid-axillary line M. In this case, the expansion and contraction adjustment unit 4 can be configured to straddle the mid-axillary line M, making it easy for the expansion and contraction adjustment unit 4 to expand and contract in the front-to-rear direction.
[0037] As an example, in the chest harness 100, the overlapping member 1 and the expansion / contraction adjustment unit 4 are configured so that the shape ratio of the front-to-back length of the thorax to the left-to-right length of the thorax (= front-to-back length / left-to-right length) when worn is larger than the shape ratio before wearing. In this case, the thorax becomes closer to a cylindrical shape, which reduces resistance in the airways and alveoli and makes breathing easier.
[0038] The present invention has been described above based on several embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications and changes are possible within the scope of the claims of the present invention, and that such modifications and changes also fall within the scope of the claims of the present invention.
