Description

[Technical Field]

[0001] The present invention relates to a posture correction device that is worn on the upper body. [Background technology]

[0002] Posture-correcting belts are known for improving poor upper body posture, such as hunched backs and rounded shoulders, and for maintaining correct posture (see, for example, Patent Documents 1 and 2). These posture-correcting belts include a back support that contacts the back when worn, left and right shoulder belts whose base ends are sewn to the back support and that are worn around the shoulders while being pulled forward, and a chest belt that is fixed to the lower end of the back support and wrapped around the chest or abdomen. The shoulder belts are uniformly stretchable in the direction of extension, applying elastic pulling force to the shoulders to correct posture. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-62245 [Patent Document 2] Japanese Patent Application Publication No. 2019-129997 Summary of the Invention [Problem to be solved by the invention]

[0004] This type of posture correction belt has a corrective principle: when worn, the shoulder belt stretches as it is placed over the shoulders from the back, and the force of this stretch corrects posture. Therefore, if the corrective force is difficult to feel, pulling the shoulder belt to increase the stretching force will result in a force that pulls the shoulders forward (i.e., in the direction of poor posture). In other words, although a certain degree of corrective force can be felt as the stretching returns to its original state after wearing, the force acting in the opposite direction to the correction during the wearing process can easily cause discomfort to the user, leaving room for improvement.

[0005] The present invention has been made in view of the above-mentioned problems, and one of its objects is to provide a posture correcting device that can effectively exert a corrective force. [Means for solving the problem]

[0006] A posture correction device according to one embodiment of the present invention comprises a waist belt that is worn around the torso of the subject, a first shoulder belt that has a fixed end on the waist belt and is pulled from the front of the subject across the left shoulder and back to the front when worn, and a second shoulder belt that has a fixed end on the waist belt and is pulled from the front of the subject across the right shoulder and back to the front when worn.

[0007] Another embodiment of the posture correction device of the present invention comprises a back support portion that contacts the back of the subject when worn, a first shoulder belt that has a fixed end on the back support portion and extends from below to above when worn and is pulled from the front side of the subject across the left shoulder and back to the front, and a second shoulder belt that has a fixed end on the back support portion and extends from below to above when worn and is pulled from the front side of the subject across the right shoulder and back to the front.

[0008] Another aspect of the present invention is a posture correction device that includes left and right shoulder belts for correcting the posture of a subject. Each shoulder belt has a configuration that applies a force that pulls the shoulder backward when the tip of the shoulder belt is pulled while wearing the device, and an elastic structure that includes regions with different elasticity along the extension direction. [Effects of the Invention]

[0009] According to the present invention, a posture correcting device that can effectively exert corrective force can be provided. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following embodiments and their modifications, substantially the same components are designated by the same reference numerals, and their description will be omitted as appropriate.

[0012] The posture correction device of this embodiment (hereinafter simply referred to as "the posture correction device") is worn on the upper body of a subject (user) to improve poor posture such as hunched back and rounded shoulders. The shoulder belts are designed and positioned so that the pulling force applied when wearing the posture correction device acts toward the rear of the shoulders, so as not to cause discomfort that could lead to poor posture when wearing the posture correction device. The shoulder belts are also positioned so as not to compress the armpits and cause discomfort when wearing the posture correction device. Details of this will be explained below.

[0013] Fig. 1 shows how a corrective brace according to an embodiment is worn. Fig. 1(A) is a view from the diagonal front, and Fig. 1(B) is a view from the diagonal rear. In the following explanation, the vertical, horizontal, and front-to-back positional relationships are expressed based on the direction seen from the perspective of the person wearing the corrective brace.

[0014] The corrective orthosis 1 includes a back support portion 10 that contacts the back (dorsal region) of the subject M, a pair of shoulder belts (left shoulder belt 12L, right shoulder belt 12R) that are hung on the left and right shoulders, and a waist belt 14 that is wrapped around the torso region (chest or abdomen). The left shoulder belt 12L corresponds to the "first shoulder belt," and the right shoulder belt 12R corresponds to the "second shoulder belt." In the following, when there is no particular distinction between the two, they will be collectively referred to as the "shoulder belt 12."

[0015] The left shoulder belt 12L has a fixed end 12Lb at the rear of the left side of the waist belt 14, and is pulled from the front side of the subject M, passing through the left shoulder, back, and right side, to the front. The right shoulder belt 12R has a fixed end 12Rb at the rear of the right side of the waist belt, and is pulled from the front side of the subject M, passing through the right shoulder, back, and left side, to the front. That is, the left and right shoulder belts 12 are hooked onto the left and right shoulders of the subject M, respectively, cross at the back support part 10, and are pulled individually forward. Then, the free ends of both shoulder belts are connected by hook-and-loop fasteners on the front side of the torso, so that the corrective orthosis 1 is stably attached to the upper body of the subject M.

[0016] Fig. 2 is a diagram showing the configuration of the orthotic device 1. Fig. 2(A) shows the inner surface, and Fig. 2(B) shows the outer surface. The orthotic device 1 has a structure that is roughly symmetrical with respect to its center line L. The waist belt 14 has a long belt body 16 that extends laterally. The belt body 16 is made of a flexible material (fabric) overall so that it fits the body when worn around the waist. A hook surface 18a of a hook-and-loop fastener 18 is provided on the inner surface of one end of the belt body 16, and a loop surface 18b of the hook-and-loop fastener 18 is provided on the outer surface of the other end. The waist belt 14 can be easily attached to and detached from the waist of the subject using the hook-and-loop fastener 18.

[0017] The back support portion 10 is provided integrally with the waist belt 14. The back support portion 10 is located between the left and right shoulder blades to form the back body, and has a shape that widens downward. The lower edge of the back support portion 10 is sewn along the upper edge of the waist belt 14. The back support portion 10 is made of a mesh material (fabric) that is flexible and highly breathable so that it fits the body when worn on the back. The upper part of the back support portion 10 is provided with a belt insertion portion 20 made of non-stretchable fabric.

[0018] The belt insertion section 20 is formed by sewing the top, bottom, left, and right four sides of a roughly octagonal patch to the back support section 10, with the remaining four sides opening diagonally. With this configuration, the belt insertion section 20 can support the shoulder belt 12 while inserting it diagonally. The belt insertion section 20 guides the extension direction of the shoulder belt 12 in the orthotic device 1 and also functions as a guide section for roughly positioning the shoulder belt 12.

[0019] The shoulder belt 12 is a long strap that includes sections with different stretchability along its extension direction. The left shoulder belt 12L has a base end sewn to the waist belt 14 as a fixed end 12Lb, and a tip end as a free end 12Lf. The fixed end 12Lb is located slightly toward the center of the left side region of the waist belt 14.

[0020] The left shoulder belt 12L has a shoulder contact portion 22 that contacts the shoulder and a back support corresponding portion 24 that contacts the back. The left shoulder belt 12L extends upward from the fixed end 12Lb, folds back downward at the shoulder contact portion 22, and is inserted obliquely into the belt insertion portion 20. The left shoulder belt 12L passes through the belt insertion portion 20 from the upper left to the lower right, and extends to the area to the right of the center line L.

[0021] On the other hand, the right shoulder belt 12R has a base end sewn to the waist belt 14 to form a fixed end 12Rb, and a tip end which forms a free end 12Rf. The fixed end 12Rb is located slightly toward the center of the right side region of the waist belt 14.

[0022] The right shoulder belt 12R has a shoulder contact portion 22 that contacts the shoulder and a back-support corresponding portion 24 that contacts the back. The back-support corresponding portion 24 is the portion that is inserted into the back support portion 10. The right shoulder belt 12R extends upward from the fixed end 12Rb, folds back at the shoulder contact portion 22, and is inserted diagonally into the belt insertion portion 20. The right shoulder belt 12R passes through the belt insertion portion 20 from the upper right to the lower left, and extends to the left side of the center line L. The left shoulder belt 12L and the right shoulder belt 12R intersect at the belt insertion portion 20. That is, as both shoulder belts 12 pass through the back support portion 10, they are closest to each other at the point of intersection.

[0023] A belt insertion portion 26L made of a patch is provided near the fixed end 12Lb of the left shoulder belt 12L. The belt insertion portion 26L is formed by sewing a rectangular, non-stretchable patch to the left shoulder belt 12L, and supports the right shoulder belt 12R by inserting it into the left shoulder belt 12L at a position near the tip of the right shoulder belt 12R. The belt insertion portion 26L functions as a "first insertion portion."

[0024] Meanwhile, a belt insertion portion 26R made of a patch cloth is provided near the fixed end 12Rb of the right shoulder belt 12R. The belt insertion portion 26R is formed by sewing a rectangular, non-stretchable patch cloth to the right shoulder belt 12R, and supports the left shoulder belt 12L by inserting it into the belt insertion portion 26R at a position near the tip of the left shoulder belt 12L. The belt insertion portion 26R functions as a "second insertion portion."

[0025] In this way, by providing the corrective brace 1 with a plurality of belt insertion portions 20, 26L, 26R, the long shoulder belt 12 does not come apart, and the corrective brace 1 can maintain its general shape. In other words, the subject M can wear the corrective brace 1 without hesitation.

[0026] In the left shoulder belt 12L, the shoulder contact portion 22 and the backrest corresponding portion 24 are non-stretchable portions 30 (see the non-colored portion in the figure), and non-stretchable material is used. Between the fixed end 12Lb and the shoulder contact portion 22 is a stretchable portion 32 (see the colored portion in the figure) made of a stretchable material. The stretchable portion 32 has superior stretchability (flexibility) than the non-stretchable portion 30. In this embodiment, the non-stretchable portion 30 facing the back is relatively large, and as shown in the figure, is set in a range from slightly above the backrest 10 to slightly below the belt insertion portion 26R.

[0027] Similarly, in the right shoulder belt 12R, the shoulder contact portion 22 and the backrest corresponding portion 24 are formed as a non-elastic portion 30. An elastic portion 32 is included between the fixed end 12Rb and the shoulder contact portion 22. The non-elastic portion 30 facing the back is relatively large, and is set in a range from slightly above the backrest 10 to slightly below the belt insertion portion 26L. The effects that the non-elastic portion 30 and elastic portion 32 have on the human body will be described later.

[0028] An elastic part 32 is provided at the tip of the left shoulder belt 12L, and on its inner surface is provided a hook surface 34a of a hook-and-loop fastener 34. Meanwhile, an elastic part 32 is also provided at the tip of the right shoulder belt 12R, and on its outer surface is provided a loop surface 34b of the hook-and-loop fastener 34. This hook-and-loop fastener 34 allows the left shoulder belt 12L and right shoulder belt 12R to be attached and detached at the front side of the torso.

[0029] Fig. 3 is a diagram showing a method for wearing the corrective appliance 1. Fig. 3(A) to Fig. 3(C) show the wearing process. When wearing the corrective orthosis 1, first, all hook-and-loop fasteners are removed, and both shoulders of the subject M are passed through the left and right shoulder belts 12. Then, with the back support portion 10 and the inner surfaces of the waist belt 14 against the back, the waist belt 14 is pulled around to the front (FIG. 3(A)). Then, both ends of the waist belt 14 are connected with the hook-and-loop fasteners 18. At this time, the waist belt 14 is positioned approximately at the height of the subject M's navel.

[0030] Next, with the back straight, the left and right shoulder belts 12 are pulled forward (Figure 3(B)). At this time, the left and right shoulder belts 12 extend and urge both shoulders backward (details will be described later). The back support portion 10 presses against the back, while the left and right shoulder belts 12 pull both shoulders backward with an appropriate elastic force, so that a force in the direction of correcting the posture of the subject M acts from the process of putting on the corrective brace 1. Then, the tip ends (free ends) of the left and right shoulder belts 12 are connected with hook-and-loop fasteners 34 (Figure 3(C)). This makes it possible to maintain the corrective force of the corrective brace 1.

[0031] 4A and 4B are diagrams showing a state in which the corrective brace 1 is worn, with Fig. 4(A) being a side view and Fig. 4(B) being a rear view. When the subject M is wearing the corrective brace 1, the non-elastic portion 30 of the shoulder belt 12 is located on the upper surface of the shoulder and at the center of the back (the position where they intersect at the top of the back support portion 10). The fixed ends (12Lb, 12Rb) of the shoulder belt 12 are located slightly behind the center Ls of the side of the subject M, and are hung from the front side to the shoulder, passed over the back, and routed to the front side.

[0032] More specifically, the fixed end 12Lb of the left shoulder belt 12L is disposed between the left side center Lf and the back center Lb of the waist belt 14. The left shoulder belt 12L is routed from the fixed end 12Lb to the front of the subject M, passing through the left shoulder, back, and right side of the subject M. On the other hand, the fixed end 12Rb of the right shoulder belt 12R is disposed between the right side center Lr and the back center Lb of the waist belt 14. The right shoulder belt 12R is routed from the fixed end 12Rb to the front of the subject M, passing through the right shoulder, back, and left side of the subject M.

[0033] The relationship between the upper body of the subject M and the elasticity of the shoulder belt 12 is as follows: That is, a non-elastic portion 30 is arranged from the front of the glenohumeral joint to near the upper edge of the scapula. This allows the corrective brace 1 to apply a compressive force at the contact surface with the subject M, exerting a sufficient force to pull the shoulder backward. In addition, an elastic portion 32 is arranged from near the upper edge of the scapula to near the medial edge of the scapula. This makes it easier for the corrective brace 1 to follow the movement of the subject's scapula.

[0034] In addition, non-elastic areas 30 are arranged from the vicinity of the medial edge of the scapula to the side of the body. This applies a compressive force at the contact surface, and a force that improves the curvature of the back is applied. When the shoulder belt 12 is pulled, the pulling force is prevented from escaping. Furthermore, elastic areas 32 are arranged from the side of the body to the tip of the belt (front of the body). This makes it easier for the corrective brace 1 to follow the movement of the chest or abdomen of the subject M.

[0035] 5 and 6 are diagrams schematically showing the effect of wearing the corrective brace 1. Fig. 5 corresponds to the configuration of this embodiment, Fig. 5(A) is a side view, and Fig. 5(B) is a plan view. Figs. 6(A) to (C) are side views corresponding to Comparative Examples 1 to 3. In the corrective brace 1 of this embodiment, the fixed ends 12b of the shoulder belts 12 are located between the side center Ls and the back center Lb of the subject M (FIG. 5(A)). More specifically, the fixed ends 12b of the left and right shoulder belts 12 are located posterior to the center P of the humeral head and anterior to the back center Lb of the waist belt 14. Therefore, when the free ends 12f of the left and right shoulder belts 12 are pulled, a sufficient force can be secured to pull the shoulders backward (see white arrows).

[0036] At the same time, a force pressing the back forward acts at the intersection point Px (the position where the left and right shoulder belts 12 are closest to each other) of the left and right shoulder belts 12 (see black arrow). In particular, because the intersection point Px is located below the center P of the humeral head, that is, because the heights of the two points are different, a rotational moment is generated by the force pulling the shoulders backward and the force pressing the back forward (see dotted arrow), which can more effectively improve poor posture (Figures 5(A) and (B)).

[0037] Furthermore, the waist belt 14 is positioned below the solar plexus (the lower end of the waist belt 14 is at approximately the same height as the navel). The fixed ends 12b of the left and right shoulder belts 12 are positioned below the position where the shoulder belts 12 are closest to each other on the back support 10 (the position where they intersect in this embodiment) (see Figs. 2(A) and 4(B)). The fixed ends 12b are positioned below the solar plexus. This also prevents or reduces pressure on the armpits.

[0038] In contrast, in Comparative Example 1, the fixed ends 12b (12Lb, 12Rb) of the shoulder belt 12 are positioned on opposite sides of the subject M's back beyond the center of the back (FIG. 6(A)). This makes it easy to compress the armpits. On the other hand, in Comparative Example 2, the fixed ends 12b of the shoulder belt 12 are positioned forward of the center of the side of the subject M (FIG. 6(B)). Specifically, the fixed ends 12b are positioned forward of the center P of the humeral head. This makes it difficult to obtain a sufficient corrective effect because the force pulling the shoulder backward is small. In Comparative Example 3, the fixed ends 12b of the shoulder belt 12 are positioned higher than the epigastrium of the subject M (FIG. 6(C)). This makes it easy to compress the armpits. In other words, by adopting the configuration of this embodiment, the corrective force of the corrective device 1 can be exerted well and without discomfort from the time of wearing it.

[0039] As described above, the corrective brace 1 of this embodiment can ensure both corrective force for improving posture and the ability to follow body movements. In this embodiment, rather than relying solely on the conventional principle of correcting posture by the return force of the shoulder belt, the position and extension direction (belt line) of the fixed end of the shoulder belt are devised to generate a force that pulls the shoulder backward from the process of putting on the corrective brace. Furthermore, by positioning the fixed end 12b of the shoulder belt 12 posterior to the center of the humeral head of the shoulder and anterior to the center of the back, compression of the axilla can be prevented or suppressed. As a result, the corrective force of the corrective brace 1 can be effectively exerted from the time of putting it on, without causing discomfort induced by poor posture or discomfort due to compression of the axilla.

[0040] Although the preferred embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this specific embodiment, and various modifications are possible within the scope of the technical concept of the present invention.

[0041] [Variations] FIG. 7 is a diagram showing the configuration (outer surface) of a corrective device according to a modified example. The corrective brace 101 includes a back support portion 110, a pair of shoulder belts 112 (a left shoulder belt 112L and a right shoulder belt 112R), and a waist belt 14. The corrective brace 101 has a configuration in which the left shoulder belt 112L and the right shoulder belt 112R do not cross each other.

[0042] The left and right shoulder belts 112 have the same configuration as the shoulder belt 12 of the above embodiment, except that the left shoulder belt 112L is provided with the loop surface 34b of the hook-and-loop fastener 34, and the right shoulder belt 112R is provided with the hook surface 34a. The positions of the fixed ends of the left and right shoulder belts 112 are the same as those of the above embodiment.

[0043] The back support portion 110 is provided with a pair of hooks 115 (115L, 115R) on the left and right sides of its upper end portion. The left and right shoulder belts 112 are folded back to the same side at the hooks 115. That is, the left shoulder belt 112L is inserted through the hook 115L and folded back to the left, and the right shoulder belt 112R is inserted through the hook 115R and folded back to the right. That is, as both shoulder belts 112 pass through the back support portion 110, they are closest to each other at the height positions where they are folded back.

[0044] FIG. 8 is a view of the orthodontic appliance 101 being worn, seen from diagonally behind. When the corrective orthosis 101 is worn, the left shoulder belt 112L is pulled from its fixed end to the front of the subject, passing through the subject's left shoulder, back, and left side. On the other hand, the right shoulder belt 112R is pulled from its fixed end to the front of the subject, passing through the subject's right shoulder, back, and right side.

[0045] The fixed end of each shoulder belt 112 is located below the position where both shoulder belts 112 are closest to each other and below the level of the solar plexus. When worn, each fixed end is located behind the center of the humeral head of the shoulder and in front of the center of the back of the waist belt 14. With this configuration, the same effects as those of the above embodiment can be obtained.

[0046] In this modified example, a pair of left and right hooks 115 are provided, and the left and right shoulder belts 112 are folded back, respectively, but it is also possible to fold back both the left and right shoulder belts using a single hook. That is, in another modified example, a single hook may be placed on the back of the subject, and the left shoulder belt may be hooked onto the left part of the hook, and the right shoulder belt may be hooked onto the right part of the hook.

[0047] In the above embodiment, the shoulder belt 12 includes a non-stretchable portion 30 and a stretchable portion 32 along its extension direction, and a material that has virtually no stretch (non-stretchable material) is used for the non-stretchable portion 30. In a modified example, a material with little stretchability (low-stretchable material) may be used for the non-stretchable portion 30. In other words, the non-stretchable portion 30 may be configured to have lower stretchability than the stretchable portion 32.

[0048] In the above embodiment, the orthotic brace has a back support portion separate from the shoulder belts. In other variations, the brace may have a configuration without an independent back support portion. For example, the left and right shoulder belts may be configured to cross at the back, with the crossing portion functioning as a back support. Alternatively, the left and right shoulder belts may not cross at the back, but the left shoulder belt may simply be routed to the front via the back and left side, and the right shoulder belt may be routed to the front via the back and right side. In this case, a connecting portion such as a strap may be provided at the back to pull the left and right shoulder belts together.

[0049] In the above embodiment, a supporter form is exemplified as the corrective brace 1. In a modified example, the corrective brace may be in the form of clothing, an adjustable belt, or other forms having the same function.

[0050] In the above embodiment, the fixed end 12b of the shoulder belt 12 is fixed to the waist belt 14 by sewing, but it may also be fixed by a button, fastener, hook, clip or other fixing means.

[0051] In the above embodiment, an example was shown in which the back support portion 10 is relatively large and flared downward. In a modified example, the lower half of the back support portion 10 may be configured to have a large opening. The back support portion and the waist belt may be connected vertically by a strap.

[0052] In the above embodiment, a configuration in which the waist belt 14 is provided in addition to the shoulder belts 12 has been exemplified. In a modified example, the left and right shoulder belts may be connected at the front side after passing through the back support portion from the front side of the subject, thereby also functioning as a "waist belt." In this way, the waist belt may be omitted.

[0053] The present invention is not limited to the above-described embodiments and modifications, and the components can be modified without departing from the spirit of the invention. Various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiments and modifications. Furthermore, some components may be omitted from all the components shown in the above-described embodiments and modifications. [Explanation of symbols]
