Description

Technical Field

[0001] The invention belongs to the field of rehabilitation wear, and in particular relates to a waist and hip support belt. Background Art

[0002] By standing upright, humans have freed their hands and expanded their horizons, giving them a significant advantage in the competition for survival and in moving toward a higher stage of evolution. However, standing upright makes the human spine upright in an "S" shape. Therefore, in order to prevent it from shifting in the four directions, the human body mainly provides support for the spine through the quadratus lumborum, iliacus lumborum, and erector spinae muscles.

[0003] However, due to certain groups of people (such as porters, office workers and other people who frequently bend over or sit for a long time), the above muscles are frequently subjected to unbalanced stress on the spine. For example, when porters are working, the lumbar iliac muscles and erector spinae muscles are always tense on one side, while the sacroiliac flexion of office workers is subjected to great stress. All of the above lead to the occurrence of lumbar muscle strain, which accelerates the damage of the spine, and seriously reduces the quality of life of porters, office workers and other groups.

[0004] At present, in order to alleviate this situation, rehabilitation wearables such as waist belts or hip protectors have appeared on the market, but these rehabilitation wearables only provide support for the four sides of the waist, that is, they only provide support around the waist, so that the protection and rehabilitation functions of these rehabilitation wearables are very limited. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a waist and hip support belt, which, in addition to supporting the waist, also provides support and exercise for related muscles or structures, forming a more three-dimensional support for the waist and hips, thereby greatly improving the protection and rehabilitation functions of the waist and hips.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A waist and hip support belt, comprising a front covering surface and a rear covering surface which are continuous along the waist, as well as a waist opening and a leg opening extending out of the thigh, wherein the direction in which the waist opening points toward the leg opening is used as the wearing direction, and is characterized in that: wherein, a crotch joint portion is formed in the middle portion of the rear covering surface extending along the wearing direction, and the crotch joint portion is connected to the surface of the front covering surface through the crotch supporting portion, thereby forming a pair of leg outlets in the leg opening portion, wherein a pair of leg outlets extend along the edge of the iliac crest in the contour section of the front covering surface, and a pair of leg outlets are directed toward the ischial tuberosity in the contour section of the rear covering surface.

[0008] Preferably, the rear covering surface also has a buttocks-exposed opening corresponding to the gluteus maximus, and the buttocks-exposed opening is close to the crotch joint along the wearing direction, and the rear covering surface between the buttocks-exposed opening and the waist opening is used as a rear supporting part, and the ratio of the rear supporting part to the buttocks-exposed opening along the wearing direction ranges from 2:1 to 2.5:1.

[0009] Furthermore, on the rear covering surface, the solid part between the buttocks-exposed opening and the crotch joint is used as a buttocks binder, and a damping enhancement layer is provided on the buttocks binder to enhance the friction between the buttocks binder and the buttocks.

[0010] Preferably, the rear covering surface further has a first supporting bag corresponding to the sacroiliac region, and the first supporting bag detachably accommodates a sacroiliac supporting entity for supporting the sacroiliac region.

[0011] Furthermore, the sacroiliac support entity is an isosceles trapezoid along the wearing direction, and the upper bottom is closer to the crotch junction than the lower bottom.

[0012] Preferably, the rear covering surface further has a second supporting bag corresponding to the erector spinae muscles, and the second supporting bag detachably accommodates an erector spinae muscle supporting entity for supporting the erector spinae muscles.

[0013] Furthermore, the number of the second supporting bags is three and they are all parallel, and the erector spinae supporting entity is a rectangular body along the wearing direction.

[0014] Furthermore, the erector spinae support entity has two specifications, one specification of the erector spinae support entity has a higher support strength, and the other specification of the erector spinae support entity has a lower support strength.

[0015] Preferably, the direction perpendicular to the wearing direction is taken as the waist direction, there are two front covering surfaces, the two front covering surfaces respectively extend on the opposite sides of the rear covering surface in the waist direction, and the free ends of the two front covering surfaces are provided with Velcro that cooperate with each other, so that the two front covering surfaces enclose a waist opening and a leg opening.

[0016] Preferably, the two side edges of the waist opening corresponding to the quadratus lumborum muscle are 1 cm to 2 cm higher than the rest of the waist opening.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Because the waist and hip support belt of the present invention has a crotch joint portion extending in the middle of the rear covering surface along the wearing direction, and the crotch joint portion is connected to the surface of the front covering surface through the crotch support portion, so that the leg opening forms a pair of leg outlets, the pair of leg outlets extend along the edge of the iliac crest in the contour section of the front covering surface, and the pair of leg outlets are toward the ischial tuberosity in the contour section of the rear covering surface, so that the waist opening provides circumferential support to the spine while forming a bottom support for the base column at the ischial tuberosity, and because the pair of leg outlets extend along the edge of the iliac crest in the contour section of the front covering surface, when the waist moves, most of the force generated by the waist muscles will be transferred to the core muscles of the abdomen through support, and the combination of the crotch joint portion and the front covering surface generates a tightening force between the waist opening and the leg opening, which further strengthens the support for the quadratus lumborum muscle. Therefore, in addition to supporting the waist, the present invention also assists the force training of the core muscles, thereby greatly improving the protection and rehabilitation functions of the waist and hips.

[0019] 2. Because the rear covering surface of the present invention also has a buttocks-exposed opening corresponding to the gluteus maximus, and the buttocks-exposed opening is close to the crotch joint along the wearing direction, the rear covering surface between the buttocks-exposed opening and the waist opening is used as a rear supporting portion, and the ratio of the rear supporting portion to the buttocks-exposed opening along the wearing direction ranges from 2:1 to 2.5:1. On the one hand, the buttocks-exposed opening avoids the physical part of the rear covering surface from directly compressing the ischial tuberosity and the nerves and blood vessels near the ischial tuberosity, including the sciatic nerve and the surrounding arteries and veins, thereby prolonging the effective action time of the waist belt. In addition, the physical part of the rear covering surface under the buttocks-exposed opening disperses the spinal support force transmitted from the buttocks along the circumference of the thigh root, thereby further reducing the pressure exerted by the spinal support force on the nerves and blood vessels near the ischial tuberosity. Therefore, the present invention can significantly reduce the pressure exerted by the spinal support force on the nerves and blood vessels near the ischial tuberosity.

[0020] 3. Because the covering surface of the present invention also has a first support bag corresponding to the sacroiliac, and the first support bag detachably accommodates a sacroiliac support entity for supporting the sacroiliac, the sacroiliac support entity of the present invention can significantly strengthen the support for the stress concentration position of the sacroiliac at the terminal curvature of the spine.

[0021] 4. Because the sacroiliac support entity of the present invention is an isosceles trapezoid along the wearing direction, and the upper bottom is closer to the crotch junction than the lower bottom, the present invention divides the spinal support force gathered in the sacroiliac into three directions through the sacroiliac support entity. One direction is transmitted to the buttocks through the upper bottom of the isosceles trapezoid and finally dispersed again through the downward pressure of the exposed buttocks. The forces in the other two directions are equal and are transmitted obliquely to the sacrotuberous ligament and the fat tissue respectively.

[0022] 5. Because the rear covering surface of the present invention also has a second support bag corresponding to the erector spinae muscles, the second support bag detachably accommodates the erector spinae muscle support entity for supporting the erector spinae muscles. Therefore, the present invention strengthens the support for the erector spinae muscles through the erector spinae muscle support entity, thereby preventing scoliosis caused by uneven lateral force on the spine.

[0023] 6. Because the erector spinae support entity of the present invention has two specifications, one specification of the erector spinae support entity has a higher support strength, and the other specification of the erector spinae support entity has a lower support strength. Therefore, the present invention is suitable for scenarios with different degrees of lateral force on the spine through two specifications.

[0024] 7. Because the two side edges of the waist opening corresponding to the quadratus lumborum muscle of the present invention are 1 cm to 2 cm higher than the other waist openings, the present invention reduces the pressure of the waist opening on the waist, abdomen and back on related movements while providing a larger support surface for the quadratus lumborum muscle on both sides, thereby making waist movements more comfortable.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and drawings are used to specifically illustrate the waist and hip support belt of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0037] like Figures 1 to 3 As shown, the waist and hip support belt 100 in this embodiment has a front covering surface 20 and a rear covering surface 10 continuous along the waist, as well as a waist opening 30 and a leg opening 40 extending out of the thigh. The direction of the waist opening 30 pointing to the leg opening 40 is taken as the wearing direction D1, and the direction perpendicular to the wearing direction D1 is taken as the waist extension direction D2. Specifically, the waist and hip support belt 100 is worn on the hip joint of a person. Therefore, the wearing reference of this embodiment is the continuous part from the lower abdomen to the thigh of a person. The human body enters the legs from the waist opening 30 along the wearing direction D1 and extends from the leg opening 40. At this time, the waist opening 30 corresponds to the waist of the human body, that is, the position of the quadratus lumborum muscle. The material of the waist and hip support belt 100 is elastic, and the elastic restoring force is used to cover the human body part to achieve support for the relevant muscle groups. In this embodiment, the waist and hip support belt 100 is made of three-layer composite fabric, the inner layer is 100% polyester, the outer layer is black 95% nylon 5% spandex, and the middle layer is rubber.

[0038] like Figure 4 and Figure 5 As shown, there are two front covering surfaces 20, which extend on opposite sides of the rear covering surface 10 in the waist span direction D2 respectively, and the free ends of the two front covering surfaces 20 are provided with Velcro 20A that cooperate with each other, so that the upper and lower edges of the two front covering surfaces 20 and the rear covering surface 10 are continuously enclosed to form a waist opening 30 and a leg opening 40.

[0039] The two side edges of the waist opening 30 corresponding to the quadratus lumborum muscle are 1 cm to 2 cm higher than the other waist openings 30. Specifically, the waist opening 30 is concave corresponding to the contours of the abdomen and back of the human body. Therefore, on the one hand, the waist opening 30 provides greater covering support for the quadratus lumborum muscle to provide stronger lateral support to the spine, that is, stabilizes the spine; on the other hand, the concave contours of the abdomen and back allow the waist opening 30 to move forward and backward appropriately, reducing pressure on the abdomen, avoiding affecting breathing or causing discomfort, and at the same time, the pressure on the back is more concentrated, and the supporting effect of the back is better.

[0040] A crotch joint portion 50 is formed in the middle portion of the rear covering surface 10 extending along the wearing direction D1. The crotch joint portion 50 supports the crotch of the human body and is connected to the surface of the front covering surface 20, so that the leg opening portion 40 forms a pair of leg outlets 50A. Specifically, the crotch joint portion 50 includes a continuous crotch section 51 and a joint section 52. The crotch section 51 is narrower than the joint section 52. The crotch section 51 corresponds to the crotch of the human body to ensure the comfort of the crotch while providing good wrapping. The inner surface of the crotch section 51 has an anti-slip layer, so as to provide an anti-slip effect in a specific direction.

[0041] Specifically, due to the human body's movements when wearing the waist support belt, including sitting, standing up, walking, etc., as well as the waist support belt's own contractility, there may be relative movements up and down or left and right between the human body and the waist support belt. Therefore, the anti-slip strip is arranged along the vertical direction of the waist support edge and at the same time spreads out in a fan shape to fit the shape of the buttocks, so as to avoid displacement during wearing, which may cause the displacement of the supporting force position and loss of wearing comfort.

[0042] A pair of leg outlets 50A extend along the edge of the iliac crest in the contour section of the front covering surface 20, and a pair of leg outlets 50A extend toward the ischial tuberosity in the contour section of the rear covering surface 10. Specifically, the ischial tuberosity is the movable connection position between the waist and hip structure and the thigh structure of the human body, and the leg outlets 50A will not restrict the movement of the thigh.

[0043] Specifically, the connecting section 52 is connected to the front covering surface 20 by means of Velcro (not shown in the drawings) arranged on the surface, so that the two front covering surfaces 20 are unfolded without being matched, and when the crotch connecting portion 50 and the front covering surface 20 are unfolded without being matched, the waist and hip support belt is in a "T" shape.

[0044] The rear covering surface 10 also has a buttocks-exposing opening 12 corresponding to the gluteus maximus, and the buttocks-exposing opening 12 is close to the crotch joint 50 along the wearing direction D1, and the rear covering surface 10 between the buttocks-exposing opening 12 and the waist opening 30 is used as the rear supporting portion 11, and the solid part between the buttocks-exposing opening 12 and the crotch joint 50 is used as the buttocks binding 13. The ratio of the rear supporting portion 11 to the buttocks-exposing opening 12 along the wearing direction D2 is in the range of 2:1 to 2.5:1, and a damping enhancement layer (not shown in the drawings) is provided on the buttocks binding 13, and the damping enhancement layer is used to enhance the friction between the buttocks binding 13 and the buttocks. Specifically, the buttocks binding 13 is in a semi-annular shape surrounding the lower part of the buttocks-exposing opening 12, as shown in FIG. Fig. 9 As shown, the hip binding 13 extends along the waist extension direction D2 on the waist side of the human body, and has an angle range of α with the front covering surface 20, and α=130-150°.

[0045] Specifically, the center points of the shapes on both sides of the buttocks-exposed opening 12 correspond to the ischial tuberosities on both sides of the lower end of the hip bones. The buttocks-exposed opening 12 avoids direct compression on the ischial tuberosities and the nerves and blood vessels nearby, including the sciatic nerve and the surrounding arteries and veins, thereby extending the effective wearing time of the waist and hip support belt 100, providing a larger activity space for daily movements and ensuring that the protection area of ​​the waist and hip support belt 100 is correct.

[0046] like Figure 6 As shown, the inner side of the rear covering surface 10 also has a first supporting bag (not shown in the drawings) corresponding to the sacroiliac region, and the first supporting bag detachably accommodates a sacroiliac supporting entity 60 for supporting the sacroiliac region.

[0047] The sacroiliac support entity 60 is an isosceles trapezoidal body along the wearing direction D1, and the upper bottom is closer to the crotch joint 50 than the lower bottom. In this embodiment, Figure 8 As shown, the sacroiliac support entity 60 is two symmetrical right-angled trapezoidal sub-entities, which support the sacroiliac from both sides of the sacroiliac respectively, and the surface facing the body surface is a silicone layer that matches the curvature of the body surface, and the rest is a hard plastic or carbon fiber that serves as a strength support structure. In addition to supporting the sacroiliac at the end of the spine, the support from both sides can also independently support the lateral bending trends of the left and right sides of the sacroiliac, thereby compensating for the differences caused by uneven structural force as a whole. For example, when walking, the left and right gluteal muscles contract alternately, and the block support can dynamically adjust the pressure distribution with muscle activity to reduce local compression.

[0048] The inner side of the rear covering surface 10 also has a second support bag (not shown in the drawings) corresponding to the erector spinae muscles and located near the first support bag. The second support bag detachably accommodates the erector spinae muscle support entity 70 for supporting the erector spinae muscles. There are three second support bags and they are all parallel. The erector spinae muscle support entity 70 is a rectangular body along the wearing direction.

[0049] The erector spinae supporting entity 70 has two specifications. One specification of the erector spinae supporting entity 70 has a higher supporting strength, and the other specification of the erector spinae supporting entity 70 has a lower supporting strength.

[0050] Specifically, the erector spinae support entity 70 is used to support the erector spinae muscle group, and the corresponding support body is inserted according to the support requirements. For example, the general population who feel sore waist and weak waist muscles when sitting for a long time need a certain support and have high requirements for comfort, and hope that the pressure is not too strong, so a hard cotton sheet material can be inserted; patients with lumbar spine diseases, lumbar disc herniation, lumbar spondylolisthesis, etc. need to have strong support that can effectively disperse the stress on the waist, provide better support and protection for the lumbar spine, and prevent the symptoms from worsening, or when performing actions that put a heavy load on the waist and hip muscles, a hard plastic support bar or a metal support bar such as a steel plate, an aluminum bar, etc. can be inserted.

[0051] Specifically, Figure 7 As shown, the erector spinae support entity 70 provides a supporting force F1 to the spine while transmitting the force transmitted from the spine to the waist and hip part through the sacroiliac support entity 60. A pair of side waist edges of the sacroiliac support entity 60 decompose the force into F3 for transmission toward the sacrotuberous ligament and adipose tissue, and the upper bottom of the sacroiliac support entity 60 decomposes the force for transmission toward the buttock opening 12.

[0052] The following is an analysis of the mechanical state of the waist and hip support belt 100 worn by a human body in combination with the embodiments:

[0053] like Fig.10 As shown, the waist and hip support belt 100 contracts the waist opening 30 through the elastic material, so that the quadratus lumborum muscle of the human body is bound to provide support force (S1, S2) on both sides of the spine, and when the crotch joint 50 is combined with the front covering surface 20 through the combination section 52, the crotch joint 50 causes the buttocks 13 to generate tension R around the outer side of the thigh, and the tension R causes the waist opening 30 to have a contraction tendency toward the leg opening 40, thereby further strengthening the support force of the quadratus lumborum muscle on both sides of the spine (S1, S2), and also allowing the core muscles of the human body to receive more force, thereby greatly improving the protection and rehabilitation functions of the waist and hips.

[0054] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the protection scope of this patent.
