Description
[Technical field]
[0001] The present invention relates to a pelvic belt. [Background technology]
[0002] Conventionally, there are pelvic belts with a restraining function. However, when fastened around the waist and abdomen, conventional pelvic belts only generate a certain amount of circumferential abdominal pressure around the waist and abdomen, and the range of support and restraint of the waist is limited. Therefore, conventional pelvic belts only have a restraining function, and are prone to slippage in the circumferential direction, resulting in insufficient support for the waist and abdomen. In addition, because elastic cords, zippers, buckles, etc. are used to fasten them, there is no stretch adjustment function, and they are less comfortable.

[0016] A description will be given of a recommended embodiment of the present invention. The present invention is not limited to the embodiment, and appropriate modifications can be made without going beyond the scope of the gist of the present invention. Although there are structures not explained or described in the embodiment, it goes without saying that known or well-known technologies can be appropriately applied to the omitted technical contents within the scope of the embodiment without causing any contradiction. In addition, although the present invention defines "left", "right", "upper", "lower", "inner" and "outer" in the drawings, these directions are uniformly based on the state in which a person wears the pelvic belt. That is, "left", "right", "upper", and "lower" are the directions felt when the user wraps the pelvic belt, and "inner" is the direction in which the pelvic belt faces the user when worn, and the opposite side is "outer". The directions limited to "upper" and "lower" are "vertical directions", and the directions limited to "left" and "right" are "horizontal directions", and the direction wrapped around the waist is the circumferential direction as shown in FIG. 13. The above definitions of the directions are intended to show the intention, and can be adjusted as necessary.
[0017] Hereinafter, a specific method for carrying out the present invention will be described. EXAMPLES
[0018] The embodiment will be described with reference to FIGS. <Pelvic belt> Fig. 1 is a rear view showing a pelvic belt 100 in the first embodiment of the present invention. Fig. 2 is a front view showing the pelvic belt 100 in the first embodiment of the present invention (back support part 7 is not shown). As shown in Figs. 1 and 2, the pelvic belt 100 of this embodiment is used to fasten the waist and abdomen of the human body, and mainly includes a connection belt 1, a pulley system 4, and a back support part 7.
[0019] <Connection Belt> As shown in FIG. 1, the connection belt 1 includes a left connection belt 102 and a right connection belt 101, and is used to wrap around and fix the waist of a user, and is composed of an inner side facing the waist and an outer side facing the waist. The left connection belt 102 and the right connection belt 101 each have a large end and a small end, and at the large end, a part of a pulley system 4 described later is installed on the outside of the left connection belt 102 and the right connection belt 101, respectively, and the distance between them is adjusted through the pulley system 4, and the inside is connected to both ends of the backrest part 7. At the small end, at both ends in the direction away from each other, the left connection belt 102 and the right connection belt 101 each have a long and thin belt shape. The long and thin belt is designed to have a shape and size that can be passed through a belt loop of a normal pair of pants, and the small end is fixed through the belt loop to ensure that the pelvic belt 100 does not deviate from the vertical design position.
[0020] As shown in FIG. 13, the left connection belt 102 is wrapped around and fixed to the left side of the waist and abdomen of the human body, and the right connection belt 101 is wrapped around and fixed to the left side of the waist and abdomen of the human body. The left connection belt 102 and the right connection belt 101 each have an inner side facing the waist and abdomen and an outer side facing the waist and abdomen. In addition, as a connection structure between the left connection belt 102 and the right connection belt 101, a loop surface of a hook fastener is designed uniformly on the outer side of the small end, and a hook surface 11 is designed on the inner side. In this embodiment, a hook surface of a hook fastener is provided on the inner side of the small end of the right connection belt, so that when fastening the pelvic belt, the user can easily bond the inner hook surface 11 of the small end of the right connection belt 101 to the outer loop surface of the left connection belt 102 to realize the fastening function. Of course, the connection structure between the left connection belt 102 and the right connection belt 101 includes, but is not limited to, the hook and loop fastener connection structure, and the connection structure can also be designed with hooks, strings, etc.
[0021] <Pulley system> 2 and 3, the pulley system 4 uses a pulley structure and includes a first pulley set A (not shown) installed on the outside of a large end of the right connection belt 101 and a second pulley set B (not shown) installed on the outside of a large end of the left connection belt 102. The first pulley set A is installed on a first tying plate 31 on the outside of a large end of the right connection belt 101, and the second pulley set B is installed on a second tying plate 32 on the outside of a large end of the left connection belt 102. The first pulley set A and the second pulley set B are connected by a string 5, and the distance between the left connection belt 102 and the right connection belt 101 can be adjusted by moving the first pulley set A and the second pulley set B through the string 5.
[0022] The first pulley group A and the second pulley group B each have two or more pulleys arranged along the vertical direction, and in this embodiment, the first pulley group A includes five pulleys 403, 405, 401, 502, 504, and the second pulley group B includes the same number of pulleys as the first pulley group, five pulleys 404, 402, 501, 505, 503. Also, as shown in Fig. 3, in the first pulley group A and the second pulley group B, the five pulleys 401, 402, 403, 404, 405 at the top of each group are the third pulley group, and the five pulleys 501, 502, 503, 504, 505 at the bottom of each group are the fourth pulley group. The five pulleys 401, 402, 403, 404, and 405 of the third pulley group are connected by a first string 501 (string 5 shown by dotted lines), and the five pulleys 501, 502, 503, 504, and 505 of the fourth pulley group are connected by a second pulley group 502 (string 5 shown by solid lines). The first pulley group A and the second pulley group B each have two holes in the horizontal direction, allowing the string 5 to pass through the first passage 451 and the second passage 45 in both directions. The first passage 451 is installed between the pulleys 401 and 502 of the first pulley group A, and corresponds to the pulley 501 of the second pulley group B in the horizontal direction. A pair of first guides 441 and 431 arranged vertically and passing horizontally are provided in a position along the horizontal direction from the right side of the first passage 451, and the second string 502 passing through the fourth pulley set is connected to the first band 201 through the pair of first guides 441 and 431. The second passage 45 is provided between the pulley 402 and pulley 501 of the second pulley set B, and corresponds horizontally to the pulley 401 of the first pulley set A. Another pair of second guides 44 and 43 arranged vertically and passing horizontally are provided in a position along the horizontal direction from the left side of the second passage 45, and the first string 501 passing through the third pulley set is connected to the second band 202 through the pair of second guides 44 and 33.
[0023] The first pulley group A uses the same number of pulleys as the second pulley group B, and the third pulley group uses the same number of pulleys as the fourth pulley group. As shown in FIG. 3, the third pulley group, the fourth pulley group, the first passage 451, and the second passage 45 are arranged so that the first pulley group A and the second pulley group B are generally symmetrical in the left-right direction, and the third pulley group and the fourth pulley group are generally symmetrical in the up-down direction. Therefore, when tightening with the string 5 (the first string 501 and the second string 502), it is ensured that the upper and lower parts of the large ends of the left connection belt 102 and the right connection belt 101 are subjected to uniform force. In addition, since the first pulley group A and the second pulley group B are arranged as an even number group that divides two groups in parallel in the vertical direction, the force is concentrated at one place and dispersed when tightening, and the upper and lower pulleys are simultaneously contracted, which effectively prevents circumferential deviation, resulting in a safer and more stable effect. In addition, the bands 201 and 202 on both sides control the upper and lower pulley sets and can be adjusted in sections to accommodate a variety of body types.
[0024] The hook surface of the hook-and-loop fastener is provided on each side of the first band 201 and the second band 202, and is used to move and connect the outer loop surface of the right connection belt and the left connection belt as desired. After the pelvic belt 100 is wrapped around the waist and abdomen, the first band 201 and the second band 202 are fixed to the right connection belt 101 and the left connection belt 102 through hook-and-loop fasteners having hook and loop surfaces, respectively. Since there is a gap between the left connection belt 102 and the right connection belt 101, the stretch of the pelvic belt 100 can be freely adjusted by manipulating the bands 201 and 202 on both sides, and the user can be provided with the most comfortable tightening effect while being fixed to the waist and abdomen. According to the present invention, when the pelvic belt 100 is further tightened, it is realized by simply manipulating the bands 201 and 202 on both sides, and the right connection belt 101 and the left connection belt 102 do not need to be peeled off, thereby improving operability.
[0025] The method of tying the string 5 will be described. The string 5 is made of a material such as nylon that has high tensile strength, excellent abrasion resistance, and is not easily deteriorated. In this embodiment, two strings 5 are used, one is a first string 501 used for the third pulley group, and the other is a second string 502 used for the fourth pulley group. In the third pulley group, one end of the first string 501 passes through the second guide 44 and the second passage 45 in order along the solid line direction indicated by the arrow in FIG. 3, turns around the pulley 401, the pulley 402, the pulley 403, the pool 404, and the pulley 405 alternately, and passes through the second passage 45 and the second guide 43 in order, and finally, both ends of the first string 501 are restrained or simultaneously connected to the second band 202 to form a closed loop.
[0026] In the fourth pulley set, one end of the second string 502 passes through the first guide 441 and the first passage 451 in sequence along the direction of the dotted line in FIG. 3, turns around pulley 501, pulley 502, pulley 503, pulley 504 and pulley 505 alternately, and passes through the second passage 451 and the second guide 431 in sequence, and finally, both ends of the first string 502 are restrained or simultaneously connected to the second band 201 to form a closed loop.
[0027] In this embodiment, it has been described that the pulley groups such as the third pulley group and the fourth pulley group are divided into two groups in the vertical direction, and each pulley group is tied with an independent string 5. There is no fixed number of groups in the vertical direction, and they can be divided into three or more groups, or the first pulley group A and the second pulley group B can be regarded as one group as a whole. That is, a single string can be wound between each pulley in the first pulley group A and the second pulley group B in order, and both ends of the string can be connected on either the left or right side, thus functioning as a band. Compared with the single-pulling method, the double-pulling method is useful for reducing the tension of one hand, and by installing multiple pulley groups in the upper and lower directions, the tension at different positions of the waist can be flexibly adjusted. Therefore, by using an even number of groups and arranging them symmetrically above and below, the above technical effect is further enhanced. Through the above-mentioned tying method, the labor-saving function of the pulley is realized, and when the user tightens it, the operation is made easier, and the stability is improved at the same time as labor is saved.
[0028] <Pulley> FIG. 4 is a perspective view showing the pulley chamber 32 of the pulley system 4 of this embodiment. FIG. 5 is a cross-sectional view taken along the axis of the pulley column 35 of the pulley system 4 of this embodiment. FIG. 6 is a perspective view showing the pulley lock tab 33 of the pulley system 4 of this embodiment. FIG. 7 is a cross-sectional view taken along the axis of the pulley body 34 of the pulley system 4 of this embodiment. FIG. 8 is a perspective view showing the assembly of the pulleys of the pulley system 5 of this embodiment. As shown in FIGS. 4 to 8, the pulleys 401, 402, 403, 404, and 405 and the pulleys 501, 502, 503, 504, and 505 are composed of the pulley chamber 32, the pulley lock tab 33, the pulley column 35, and the pulley body 34.
[0029] As shown in FIG. 4, the pulley chamber 32, the pulley column 35 and the string plate 3 are integrally configured. Among them, the pulley chamber 32 protrudes outward from the string plate 3 and is formed as a nearly cylindrical chamber with a bottom that opens inward. The first pulley set A has two openings parallel to each other along the vertical direction on the side where the pulleys 403, 405, 401, 502, 504 face the second pulley set B, which serve as the inlet 41 and the outlet 52 for the string 5. Similarly, the second pulley set B has two openings parallel to each other along the vertical direction on the side where the pulleys 404, 402, 501, 505, 503 face the first pulley set A, which serve as the inlet 51 and the outlet 52 for the string 5.
[0030] As shown in Fig. 4 and Fig. 5, the pulley column 35 is a hollow cylinder, and one end of the pulley column 35 is integrated with the pulley chamber 32 at the center of the bottom of the pulley chamber 32. Also, as shown in Fig. 5, the pulley body 34 and the pulley lock tab 33 described later are attached to the other end of the pulley column 35 in this embodiment, and the edge warping is integrated by hot riveting, so that the positions of the pulley body 34 and the pulley lock tab 33 described later can be fixed. It is to be noted here that the other end of the pulley column 35 is not the only way to warp the edge outward with hot rivets to fix the positions of the pulley body 34 and the pulley lock tab 33 described later, and it is also possible to fix the positions by changing the structure of the pulley column 35 and the pulley lock tab 33 in the third embodiment described later. It is also to be noted that the pulley column 35 can be a solid cylinder.
[0031] As shown in FIG. 4, a pulley holding part 351 having a diameter larger than that of the pulley column 35 and sharing an axis with the pulley column 35 is integrally formed at the bottom of the pulley chamber 32. There may or may not be a gap between the pulley holding part 351 and the pulley column 35. The height of the pulley holding part 351 is as low as that of the pulley column 35, and the height is designed so that the pulley lock tab 34 can be inserted even if the edge is bent outwardly by hot riveting at the other end of the pulley column 35. It is also possible to omit the pulley holding part 351, that is, the diameter of the hole in the center of the pulley body 34 described later matches the diameter of the pulley column 35, and a gap is provided between the pulley body 34 and the pulley lock tab 33 to prevent large friction when the edge is bent outwardly by hot riveting at the other end of the pulley column 35 when assembling the pulley.
[0032] As shown in Fig. 6, the pulley lock tab 33 is formed in an approximately cylindrical shape, and a hole is provided in the center that matches the diameter of the pulley holding part 351 (or the pulley column 35 when the pulley holding part 351 is omitted), and radially protruding ears are provided at positions corresponding to the two openings of the pulley chamber 32 as the entrance 51 and exit 52 of the string 5 to cover the inner gaps of the entrance 51 and exit 52 of the string 5. Since the inner gaps of the entrance 51 and exit 52 of the string 5 are produced by molding, the size of the ears is also small, and the pulley lock tab 33 does not affect the position of the pulley body 34 and the string 5, so it is possible to not provide ears on the pulley lock tab 33. 7, the cross section of the pulley body 34 taken along the axis is roughly rectangular, with a V-shaped groove formed on the short side of the rectangle to store the string 5, and a hole aligned with the diameter of the pulley holding part 351 (or the pulley column 35 when the pulley holding part 351 is omitted) formed in the center of the rectangle. It is illustrative to say that forming a V-shaped groove on the short side of the rectangle is not the only option, and it is also possible to form a curved or concave groove to store the string 5.
[0033] The assembly of the pulley will be described. First, the pulley body 34 is inserted into the pulley holding part 351 integrated with the pulley chamber 32, then the lugs of the pulley lock tab 33 are inserted into the pulley column 35 in the direction corresponding to the inlet 51 and outlet 52 of the string 5, and finally, the pulley lock tab 33 is connected to the end of the pulley holding part 351 by bending the other end edge of the pulley column 35 by a hot riveting method, thus fixing the positions of the pulley body and the pulley lock tab 33. Therefore, as shown in FIG. 8, the cylindrical side wall of the pulley chamber 32 and the V-shaped concave wall of the cylinder of the pulley body 34 are formed as a passage for the string 5, and a small gap is opened between the cylindrical side wall of the pulley chamber 32 and the maximum outer wall of the cylinder of the pulley body 34. In addition, when the pulley lock tab 33 is connected to the end of the pulley holding part 351 by bending the other end edge of the pulley column 35 by hot riveting, the size from the bottom wall of the pulley chamber 32 to the pulley lock tab 33 is slightly larger than the thickness of the pulley body 34 (in other words, the height of the pulley holding part 351 is slightly larger than the thickness of the pulley body 34), the diameter of the inner wall of the hole of the pulley body 34 is slightly larger than the diameter of the outer wall of the pulley holding part 351, and both end faces in the thickness direction of the pulley body 34 are parallel to the bottom wall of the pulley chamber 32 and the pulley lock tab 33, respectively. By designing the above gap and size, the friction of the pulley body 34 in the pulley chamber 32 can be reduced.
[0034] In this way, when assembling the pulley system 4, the strings 5 are inserted into the entrance 51 and the exit 52, respectively, so that the pulleys 401, 402, 403, 404, 405 and the pulleys 501, 502, 503, 504, 505, as well as the first string 501 and the second string 502 are stored in the pulley chamber 32, and are fixed in the pulley chamber 32 by the pulley lock tab 33 installed at the top of the pulley chamber 32 and the pulley column 35 installed to penetrate the pulley main body 34 and the pulley lock tab 33. This prevents the pulleys 401, 402, 403, 404, 405 and the pulleys 501, 502, 503, 504, 505, as well as the first string 501 and the second string 502 from coming off, and ensures the normalization of the adjustment function.
[0035] In this embodiment, the pelvic belt includes the structure of the backrest 7, but the pulley structure described above can be applied to various pelvic belts that use a pulley system. In other words, even if the pelvic belt does not include the traditional structure of the backrest 7, it is protected by the claims of the present invention by simply adopting the pulley structure of this embodiment.
[0036] <Backrest> As shown in FIG. 1, the pelvic belt is installed inside the connection belts 1 (left connection belt 102 and right connection belt 101) so as to face the pulley system 4, with the connection belts 1 being separated. In addition, both ends of the backrest part 7 are connected to the left connection belt 102 and the right connection belt 101 through the connection structures described below, respectively, so that the backrest part 7 can move horizontally relative to the left connection belt 102 and the right connection belt 101. As shown in FIG. 9 and FIG. 13, the backrest part 7 has a protrusion 72 in the center and connection parts 71 on the outsides of both ends. Among them, the pelvic belt has a protrusion 72 installed between the left connection belt 102 and the right connection belt 101, and the connection parts 71 are connected to the left connection belt 102 and the right connection belt 101 on the inside, respectively.
[0037] As shown in Fig. 9 and Fig. 13, the backrest 7 is composed of a base plate 74, a pad 76, and a backrest bag 75, and the base plate 74, the pad 76, and the backrest 75 are arranged in order along the inner side. That is, the pad 76 and the backrest bag 75 are arranged in order along the inner side on the protrusion 72. A part of the edge of the backrest bag 75 is sewn to the inner surface of the base plate 74 corresponding to the protrusion 72 to form an opening, through which the pad 76 can be inserted or removed. Preferably, a part of the edge of the backrest bag 75 is sewn to the inner surface of the base plate 74 corresponding to the protrusion 72 to form two openings along the horizontal direction, so that the shuttle-shaped pad 76 described below can be conveniently inserted or removed.
[0038] The pad 76 is made of an elastic material with a uniform thickness, and can alleviate discomfort caused by the hard back support portion 7, and can adjust the angle of the pad 76 to the lumbar vertebrae to maintain stability of the trunk. Preferably, the pad 76 is formed so that the cross section along the horizontal and vertical directions corresponding to the back support bag 75 is shuttle-shaped. More preferably, the pad 76 is formed convex. The back support portion 7 can be smoothly overstretched upwards and / or downwards along the vertical direction, and is formed roughly shuttle-shaped, so that the pelvic belt 100 of the present invention can increase the coverage rate of the lumbar vertebrae in the vertical direction, and reduce pressure on both sides of the lumbar vertebrae along the horizontal direction, especially the ribs and lumbar bones, improving comfort.
[0039] The protrusion 72 of the backrest 7 will be described. The protrusion 72 includes a backrest bag 75 and a pad 76. The pad 76 is structured to protrude slightly inward, so that when the pad 76 is inserted into the backrest bag 75, the protrusion 72 protrudes inward from the base plate 74. Usually, a number of pads 76 with different protrusion sizes can be prepared, so that the total height of the backrest 7 can be adjusted to suit different people, and the range of application of the pelvic belt 100 according to the utility model can be expanded. In addition, the pad 76 constituting the protrusion 72 can be replaced with an inflatable airbag (not shown). An uninflated airbag is first loaded into the backrest bag 75, and then inflated to make the protrusion 72 protrude inward from the base plate 74. Therefore, the user can freely grasp the degree of inflation of the airbag, flexibly adjust the hardness of the airbag, and improve comfort.
[0040] As shown in Fig. 10, the base plate 74 of the backrest 7 can be integrally formed with the protrusion 72, of which the protrusion 72 is obviously thicker than the connection part 71 and protrudes inward to form a circle. Although not shown in the figure, the thickness of the protrusion 72 can be made the same as that of the connection part 71, forming an arch bridge shape, with the arch part protruding inward to form a circle, and such a structure can reduce the weight and prevent the user from feeling the weight. At the same time, the circular protrusion 72 with a uniform thickness has a certain elasticity, improving the comfort of use.
[0041] Therefore, the backrest 7 having the protrusion 72 enhances the support force for the abdomen and lumbar region. In addition, when the pelvic belt 100 is fastened, the backrest 7 automatically simulates the shape of the body, enhancing the support effect adapted to the lumbar region and the abdomen. In addition, the backrest 7 is installed at the center of the large end of the left connection belt 102 and the large end of the right connection belt 101 to support the lumbar region, and the pad 76 generates pressure in the lumbar direction as the large end of the left connection belt 102 and the large end of the left connection belt 101 contract and pull, thereby maintaining the lumbar vertebrae at an appropriate angle, stabilizing the trunk, and adjusting the posture of the body. In addition, a loop surface of a hook-and-loop fastener is installed on the inner surface of the protrusion 72 facing the backrest bag 75, and at least one elongated hook-and-loop fastener is provided, one end of which is fixed to the backrest bag 75 and the other end of which has a hook-and-loop fastener hook surface extending horizontally. Of these, the elongated hook-and-loop fastener is designed to be wide enough to pass through the belt loop of normal trousers, and by passing the elongated hook-and-loop fastener through the belt loop of normal trousers and adhering it to the hook surface of the hook-and-loop fastener on the backrest bag 75, the backrest portion 7 with the protrusion 72 is ensured not to move out of its designed vertical position.
[0042] <Connection structure between the backrest and the connection belt> The connection structure between the backrest 7 and the connection belt 1 includes guides 711 installed on the outside of both ends of the backrest 7, and rod-shaped elastic cord buckles 6 installed horizontally on the inside of the overlapping parts of the left connection belt 102 and the right connection belt 101, as shown in FIG. 11. As shown in FIG. 12, the elastic cord buckles 6 can move relatively along the horizontal direction in the guides 711. This connection structure ensures that the left connection belt 102 and the right connection belt 101 are connected to the backrest 7 and that the relative change in the relative distance between the left connection belt 102 and the right connection belt 101 can be guaranteed, so that the tightness of the pelvic belt 100 in the present invention can be adjusted when the backrest 7 is stationary. It is to be noted that the above connection structure including the elastic cord buckles 6 and the guides 711 is not unique, and it is also possible to connect using a T-shaped tank or an H-shaped tank.
[0043] For example, it may be constructed by taping (not shown) installed on both ends of the backrest portion 7, and the length of the taping can be adjusted by connecting the taping to length adjustment structures (not shown) such as a square or eye shape on the left connection belt 102 and the right connection belt 101, respectively, thereby adjusting the relative positions of the backrest portion 7, the left connection belt 102, and the right connection belt 101.
[0044] <Tightening the pelvic belt> The tightening operation of the pelvic belt 100 will be described. As shown in Fig. 13, the pelvic belt 100 including the projection 72 and the back support 7 of the present invention is placed on the waist and abdomen so that the projection 72 corresponds to the lumbar vertebrae, and the left connection belt 102 and the right connection belt 101 are moved inward along the circumferential direction on both the left and right sides of the waist and abdomen until the pelvic belt 100 is basically in close contact with the abdomen and waist, and immediately after that, the inner hook surface 11 of the small end of the right connection belt 101 is attached to the outer loop surface of the left connection belt 102. Next, the user operates the band 2 inward along the circumferential direction from both the left and right sides of the waist and abdomen to tighten the belt. At the same time, the large ends of the left connection belt 102 and the right connection belt 101 are contracted to the protrusion 72 at the horizontal center of the backrest 7 until the pressure on the lumbar vertebrae is adjusted, and immediately thereafter, the hook surfaces of the hook-and-loop fasteners of the two left and right bands 2 (first band 202 and first band 201) are attached to the outer loop surfaces of the left connection belt 102 and the right connection belt 101, respectively, to tighten them. During tightening, the pad 76 in the protrusion 72 installed on the backrest 7 applies pressure to the lower back and abdomen, contributing to an increase in intraperitoneal pressure, thereby maintaining an appropriate angle for the lumbar vertebrae and sacrum, preventing localized areas of the lumbar vertebrae from being unsupported and damaged, adjusting the body posture to stabilize the trunk, and reducing the sense of weakness in the lower back. EXAMPLES
[0045] The second embodiment will be described with reference to FIG. 14. FIG. 14 is a front view showing a lacing method of the pulley system 41 according to the second embodiment of the present invention. The second embodiment is different from the first embodiment in the pulley system, and the same parts as the first embodiment are shown in the same figure. The specific implementation method is omitted. As shown in FIG. 14, the pulley system 41 adopts a fixed pulley structure and includes a first pulley set A1 (not shown) on the outside of the big end of the right connection belt 101 and a second pulley set B1 (not shown) on the outside of the big end of the left connection belt 102. The first pulley set A1 is installed on the first lacing plate 31, one end of which is fixed to the outside of the big end of the right connection belt 101, and the second pulley set B1 is installed on the second lacing plate 32, one end of which is fixed to the outside of the big end of the left connection belt 102. The first pulley group A1 and the second pulley group B1 are connected by a string 5 (first string 50 and second string 51), and the distance between the left connection belt 102 and the right connection belt 101 can be adjusted through relative movement between the string 5 (first string 50 and second string 51) and the first pulley group A1 and the second pulley group B1.
[0046] The first pulley group A1 and the second pulley group B1 each consist of two or more fixed pulleys arranged along the vertical direction. In this embodiment, the first pulley group A1 includes four fixed pulleys 4021, and the second pulley group B1 also includes four pulleys 4011. In addition, the four fixed pulleys 4011 and 4021 at the upper part of each of the first pulley group A1 and the second pulley group B1 constitute a third pulley group, and the four fixed pulleys 4011 and 4021 at the lower part of each of the first pulley group A1 and the second pulley group B1 constitute a fourth pulley group. The third pulley group and the fourth pulley group are connected by an independent first string 50 (string 5 in solid line) and a second string 51 (string 5 in dotted line), respectively. At the same time, the first pulley group A1 and the second pulley group B1 each have a hole penetrating in the horizontal direction, so that the string 5 can pass through the passage 4511 in one direction. The passage 4511 on the first pulley group A1 side is provided on the fourth pulley group side, and the passage 4511 on the second pulley group B1 side is provided on the third pulley group side. A string 3011 is provided on the upper end of the first string plate 31 corresponding to the first pulley group A1, and a string 3021 is provided on the lower end of the second string plate 32 corresponding to the second pulley group B1.
[0047] A method of tying the string 5 (first string 50 and second string 51) will be described. For the third pulley group, one end of the first string 50 is fixed to the buckle 3011 of the first string plate 31, and the other end crosses and turns around two fixed pulleys 4011 and two fixed pulleys 4021 of the third pulley group, and passes through the passage 4511 and the second guide 43 of the second string plate 32 to be fixed to the second band 202. Similarly, for the fourth pulley group, one end of the second string 50 is fixed to the buckle 3021 of the second string plate 32, and the other end crosses and turns around two fixed pulleys 4011 and two fixed pulleys 4021 of the fourth pulley group, and passes through the passage 4511 and the first guide 431 of the first string plate 32 to be fixed to the first band 201. In this way, the first string 50 and the second string 51 are operated simultaneously to adjust the first string plate 31 and the second string plate 32, i.e., the left connection belt 102 and the large end of the left connection belt 102 are contracted to the protrusion 72 located at the horizontal center of the backrest 7. Although force is required to operate the fixed pulley, the direction of the force can be changed. At the same time, the adjustment accuracy of the strings 5 (the first string 50 and the second string 51) is improved by repeatedly changing the direction of the fixed pulley. The above is an explanation of the string tying method of the pulley system 41 in this embodiment. EXAMPLES
[0048] The third embodiment will be described with reference to Figs. 15 and 17. Fig. 15 is a perspective view showing the pulley chamber 32 of the pulley system 4 in the third embodiment of the present invention. Fig. 16 is a perspective view showing the pulley lock tab 33 of the pulley system 4 in the third embodiment of the present invention. Fig. 17 is a cross-sectional view taken along line A-A in Fig. 16 during assembly of the pulley system 4 in the third embodiment of the present invention. This embodiment differs from the first and second embodiments in the structure of the pulley, and the same parts as those in the first and second embodiments are shown in the same figures. A specific implementation method is omitted. In addition, if there is no contradiction in the technical means, the first to third embodiments can be combined with each other.
[0049] As shown in FIG. 15, the pulley chamber 32 retains the pulley holding part 351 by removing the pulley column 35, or retains the pulley holding part 351 by removing the pulley holding part 351. At the same time, the pulley holding part 351 or the pulley column 35 has lock holes 36 that are symmetrically arranged on the left and right sides of the circumference. Also, as shown in FIG. 16, the central hole of the pulley lock tab 33 has a bolt 37. The bolt 37 is configured to extend radially in the axial direction by a certain amount from the inner wall of the central through hole of the pulley lock tab 33 at a position corresponding to the lock hole 36, and forms a substantially H-shaped through hole. Therefore, the pulley body 34 and the pulley lock tab 33 are fixed by inserting the bolt 37 into the fixed lock of the lock hole 36.
[0050] The structure of the pulley in this embodiment will be described. As shown in Fig. 17, first, the pulley body 34 is inserted into the pulley holding part 351 integrated with the pulley chamber 32 or the pulley column 35, and then the bolt 37 of the pulley lock tab 33 is fixed into the lock hole 36 of the pulley holding part 351 or the pulley column 35, thereby fixing the pulley body 34 and the pulley lock tab 33. This concludes the description of the pulley in this embodiment.
[0051] The above-mentioned embodiments are used to explain the technical idea of the present invention, and are not used for the purpose of limitation. Although the embodiments explain the present invention in detail, those skilled in the art can understand it. They can still replace some or all of the technical features of the embodiments. Such modifications and replacements do not deviate from the essence of the relevant technical idea and the technical proposal of the embodiments of the present invention. [Explanation of symbols]
