[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. The present invention can be implemented in various embodiments, and is not limited to the embodiments described below.

[0011] <Structure of the spine of the assist suit> Fig. 1 is a diagram showing an example of the configuration of the spine member of an assist suit. The spine member 20 of the assist suit in Fig. 1 has a vertically long shape extending from the back to the buttocks of the wearer, curves along the wearer's back, and is made of a material that has elasticity in the bending direction. The spine member 20 has a first slit 21 that slidably holds the shoulder belt 11 and a second slit 22 that slidably holds the waist belt 12.

[0012] The left and right shoulder belts 11 for fixing the spine member to the back of the wearer are held by the spine member 20 through the first slits 21 and connected to the spine member 20 via the front of the wearer. By adjusting the length of the left and right shoulder belts 11, the spine member 20 can be fitted closely to the back of the wearer. The waist belt 12 is held by the spine member 20 through the second slits 22 and connected to the waist attachment part in the front of the wearer, so that the spine member 20 can be fitted closely to the waist of the wearer. The waist belt 12 may be configured so that the length can be adjusted according to the body shape of the wearer, or waist belts of different lengths may be replaced.

[0013] The first slit 21 of the spine member 20 slidably holds the shoulder belt 11 and has a length that allows the position at which the shoulder belt 11 is held to be changed, thereby allowing the position at which the shoulder belt 11 is worn to be changed to suit the wearer's body shape. Similarly, the second slit 22 of the spine member 20 slidably holds the waist belt 12 and has a length that allows the position at which the waist belt 12 is held to be changed, thereby allowing the position at which the waist belt 12 is worn to be changed to suit the wearer's body shape.

[0014] By using the spine member 20, shoulder belts 11, and waist belt 12 configured as described above, the spine member 20 can be fitted closely to the back and waist of the wearer to suit wearers of various body shapes. By fitting the spine member 20 closely to the back and waist of the wearer, the back and waist of the wearer and the spine member 20 become one, correcting the posture of the wearer and assisting the wearer in bending forward by the elastic force of the spine member 20. In this configuration example, the shoulder belts 11 and waist belt 12 for fitting closely to the back and waist of the wearer are directly connected to the spine member 20, so that it is possible to provide an assist suit that is comfortable to wear and does not interfere with the wearer's work, even when working in a place with high temperatures in summer or for a long time.

[0015] The spine member 20 in this configuration example has a vertically long shape extending from the back to the buttocks of the wearer, curves along the back of the wearer, and is made of a material having elasticity in the bending direction. The material constituting the spine member 20 can be made of a material such as a metal material or a resin material having elasticity in the bending direction, but is not limited to these materials. The length and material of the spine member may be changed appropriately according to the body shape and physical strength of the wearer.

[0016] 1, the width of a portion above the longitudinal center of the spine member 20, for example, a portion near the shoulder blades of the wearer's back, is configured to be relatively narrower than other portions. With this configuration, the spine member can be configured so as to maintain the elasticity of the spine member while minimizing the inhibition of the twisting motion of the wearer's upper body.

[0017] <Configuration of the assist suit's waist attachment part> 2 is a diagram showing a configuration example of the waist attachment part of the assist suit. The waist attachment part 40 is attached to the waist of the wearer and includes a first connecting part 41 for connecting to the spine member 20, and optionally includes a second connecting part 42 for connecting to the foot attachment part.

[0018] The waist attachment section 40 is connected to the spine member 20 by a first connecting section 41, and by tightening the waist of the wearer when worn, the spine member 20 can be fixed to the waist of the wearer. By fixing the spine member 20 to the waist of the wearer, it is possible to prevent the spine member 20 from shifting in the vertical direction when the wearer of the assist suit bends forward, and therefore it is possible to further enhance the effect of assisting the wearer's bending forward motion compared to the case of only the spine member 20.

[0019] When the assist suit includes a foot attachment part, the waist attachment part 40 includes a second connecting part 42 for connecting with the foot attachment part. The first connecting part connecting the spine member 20 may be configured to include a third slit 43 for slidably holding the foot belt 31 of the foot attachment part. The foot attachment part can be directly connected to the spine member 20 via the third slit 43.

[0020] <Configuration of the assist suit's foot attachment section> Fig. 3 is a diagram showing a configuration example of the foot attachment part of the assist suit. The assist suit equipped with the spine member 20 of Fig. 1 and the waist attachment part 40 of Fig. 2 can correct the posture of the wearer and assist the wearer in bending forward, but by providing foot attachment parts 30 to be attached to the wearer's feet in addition to the spine member 20 and the waist attachment part 40, it is possible to further enhance the effect of assisting the wearer in bending forward.

[0021] The foot attachment part 30 of the assist suit in Figure 3 is equipped with a fixing member 32 for fixing to the wearer's knees, and a foot belt 31 made of an elastic member and connected to the fixing member 32, and the foot attachment part 30 can be connected to the waist attachment part 40 by connecting the foot belt 31 to a second connecting part 42 of the waist attachment part 40.

[0022] The fixing members 32 are cylindrical members for fixing to the left and right knees of the wearer, and are fixed to the knees of the wearer by tightening them from the periphery. The fixing members 32 may be cylindrical belts with holes for fixing to the knees, as shown in the cross-sectional view of Fig. 3, or may be belt-shaped members with engaging means such as hook-and-loop fasteners that engage above and below the knees.

[0023] The foot belt 31 is made of an elastic material. The foot belt 31 made of an elastic material is connected to the waist attachment part 40 and connected to the fixing member 32 fixed to the knee part of the wearer. Therefore, when the wearer bends forward, the foot belt 31 stretches and contracts, and a force that assists the wearer's bending forward can be applied to the waist attachment part 40 and the spine member 20 connected to the waist attachment part 40.

[0024] In addition, the first connecting part 41 of the waist attachment part 40 has a third slit 43 that slidably holds the foot belt 31, and by connecting the foot belt 31 to the first connecting part 41 via the third slit 43, the foot attachment part 30 is directly connected to the spine member 20 via the first connecting part 41, thereby further enhancing the effect of assisting the wearer's forward bending motion.

[0025] The foot attachment part 30 is detachably connected to the waist attachment part 40, so that the wearer can attach and detach the foot attachment part 30 to change the configuration of the assist suit according to the type of work to be performed, and adjust the degree of the assist effect. The configurations of the foot belts 31 and fixing members 32 of the foot attachment part can also be appropriately changed according to the body shape and physical strength of the wearer.

[0026] <Assist Suit Configuration> An example of the configuration of the assist suit 10 according to the embodiment of the present invention will be described with reference to Figures 4 and 5. The example of the configuration in Figure 4 is obtained by connecting the spine member 20 in Figure 1 and the waist attachment part 40 in Figure 2, and the example of the configuration in Figure 5 is obtained by further connecting the foot attachment part 30 in Figure 3 to the configuration in Figure 4.

[0027] As shown in FIG. 4, by connecting the spine member 20 and the waist attachment part 40 and bringing the spine member 20 into close contact with the wearer's back and waist with shoulder belts 11 and waist belt 12, and further fixing the waist attachment part 40 connected to the spine member 20 to the wearer's waist, it is possible to correct the wearer's posture and assist the wearer in bending forward.

[0028] In the configuration example of Fig. 5, the foot attachment part 30 of Fig. 3 is further connected to the configuration of Fig. 4. As shown in Fig. 5, in addition to the spine member 20 and the waist attachment part 40, the foot attachment part 30 including the elastic foot belt 31 and the fixing member 32 is fixed to the knee part of the wearer and connected to the waist attachment part 40 by the second connecting part 42, which further enhances the effect of assisting the wearer's forward bending motion.

[0029] Furthermore, as shown in FIG. 5, by connecting the foot belt 31 of the foot attachment part 30 to the first connecting part 41 via a third slit 43 provided in the first connecting part 41 for connecting the spine member 20 of the waist attachment part 40, the foot attachment part 30 is directly connected to the spine member 20 via the first connecting part 41, thereby further enhancing the effect of assisting the wearer's forward bending motion.

[0030] <Example of the configuration of the assist suit> Fig. 6 is a diagram showing a configuration example of an assist suit being worn. Fig. 6 shows the assist suit 10, which is equipped with the spine member 20 and waist attachment part 40 described in Fig. 4, worn by the wearer 1. In the side view of Fig. 6, for convenience of explanation, the spine member 20 is shown separated from the wearer 1, but in the present invention, the spine member 20 is as closely attached to the back and waist of the wearer 1 as possible, and the wearer 1 and the spine member 20 are configured to operate as a unit. The same applies to the other figures.

[0031] 6, the spine member 20 of the assist suit 10 has a vertically long shape extending from the back to the buttocks of the wearer 1, curves along the back of the wearer 1, and is made of a material that has elasticity in the bending direction. The spine member 20 has a first slit 21 that slidably holds the shoulder belt 11 and a second slit 22 that slidably holds the waist belt 12.

[0032] The left and right shoulder belts 11 for fixing the spine member 20 to the back of the wearer 1 are connected to the spine member 20 via first slits 21, and are connected to the spine member 20 via the front of the wearer 1. By adjusting the length of the left and right shoulder belts 11, the spine member 20 can be fitted closely to the back of the wearer 1. The waist belt 12 is held by the spine member 20 via a second slit 22, and is connected to the waist attachment part 40 on the front of the wearer 1, so that the spine member 20 can be fitted closely to the waist of the wearer 1. The waist belt 12 can be connected to the waist attachment part by an engagement means such as a hook-and-loop fastener, and the connection position can be appropriately changed according to the body shape of the wearer.

[0033] The waist attachment portion 40 has a first connecting portion 41 for connecting to the spine member 20, and is connected to the spine member 20 by the first connecting portion 41. When worn, the spine member 20 can be fixed to the waist of the wearer 1 by tightening the waist of the wearer 1.

[0034] The first slit 21 of the spine member 20 slidably holds the shoulder belt 11 and has a length that allows the position at which the shoulder belt 11 is held to be changed, so that the wearing position of the shoulder belt 11 can be changed to suit the body shape of the wearer 1. The second slit 22 of the spine member 20 similarly holds the waist belt 12 slidably and has a length that allows the position at which the waist belt 12 is held to be changed, so that the wearing position of the waist belt 12 can be changed to suit the body shape of the wearer 1.

[0035] By using the spine member 20, shoulder belt 11, waist belt 12, and waist attachment part 40 configured as described above, the spine member 20 can be fitted closely to the back and waist of the wearer 1 according to various body shapes of the wearer. By fitting the spine member 20 closely to the back of the wearer 1, the back and waist of the wearer 1 and the spine member 20 become one, correcting the posture of the wearer 1 and assisting the forward bending motion of the wearer 1. By fixing the waist attachment part 40 connected to the spine member 20 to the waist of the wearer 1, it is possible to prevent the spine member 20 from shifting in the up and down direction when the wearer 1 bends forward, and therefore it is possible to further enhance the effect of assisting the wearer's forward bending motion.

[0036] Furthermore, in the present invention, the shoulder belts 11 and waist belts 12 for fitting the spine member 20 closely to the back of the wearer 1 are directly connected, making it possible to provide an assist suit 10 that is comfortable to wear and does not interfere with the work of the wearer 1, even when working in hot places in summer or for long periods of time.

[0037] <Other configuration examples of the worn assist suit> Fig. 7 is a diagram showing another example of the configuration of the worn assist suit. Fig. 7 shows the assist suit 10, which includes the spine member 20, the waist attachment unit 40, and the foot attachment unit 30 described in Fig. 5, worn by the wearer 1. In the configuration example of Fig. 7, by further including the foot attachment unit 30 in addition to the spine member 20 and the waist attachment unit 40, it is possible to further enhance the effect of assisting the forward bending motion of the wearer 1.

[0038] The foot attachment part 30 of the assist suit 10 in Figure 7 is equipped with a fixing member 32 for fixing to the knee of the wearer 1, and a foot belt 31 made of an elastic member and connected to the fixing member 32, and the foot attachment part 30 can be connected to the waist attachment part 40 by connecting the foot belt 31 to a second connecting part 42 of the waist attachment part 40.

[0039] The fixing members 32 are cylindrical members for fixing to the left and right knees of the wearer 1, and are fixed to the knees of the wearer 1 by tightening them from the periphery. The fixing members 32 may be configured as cylindrical belts with holes for fixing to the knees, or may be configured as belt-like members with engaging means such as hook-and-loop fasteners that engage above and below the knees.

[0040] The foot belt 31 is made of an elastic material. The foot belt 31 made of an elastic material is connected to the waist attachment part 40 and connected to the fixing member 32 fixed to the knee part of the wearer 1. Therefore, when the wearer 1 bends forward, the foot belt 31 stretches and contracts to apply a force to assist the forward bending motion to the waist attachment part 40 and the spine member 20 connected to the waist attachment part 40. This makes it possible to further enhance the effect of assisting the forward bending motion of the wearer 1 compared to the case where there is no foot attachment part as shown in FIG. 6.

[0041] In addition, the first connecting part 41 of the waist attachment part 40 has a third slit 43 that slidably holds the foot belt 31, and by connecting the foot belt 31 to the first connecting part 41 via the third slit 43, the foot attachment part 30 is directly connected to the spine member 20 via the first connecting part 41, thereby further enhancing the effect of assisting the wearer 1 in bending forward.

[0042] <Assist Suit Operation> Fig. 8 is a diagram showing an example of the motion of the assist suit when the wearer bends forward. Fig. 8 shows an example of the motion of the wearer 1 bending forward while wearing the assist suit 10 having the spine member 20 and the waist attachment part 40 as described in Fig. 6.

[0043] The shoulder belts 11 held by the spine member 20 are connected to the spine member 20 via the front of the wearer 1, and by adjusting the length of the shoulder belts 11, the spine member 20 is brought into close contact with the back of the wearer 1, and the waist belt 12 is connected to the waist attachment part 40 on the front of the wearer 1, thereby bringing the spine member 20 into close contact with the waist of the wearer 1. The waist attachment part 40 is connected to the spine member 20 by a first connecting part 41, and fastens the waist of the wearer 1 when worn, thereby fixing the spine member 20 to the waist of the wearer 1.

[0044] As shown in FIG. 8, when the spine member 20 is in close contact with the back of the wearer 1 and the wearer 1 bends forward, the spine member 20 moves integrally with the back of the wearer 1, and therefore, due to the elastic force of the spine member 20 in the bending direction, a force acts in the direction of raising the back of the wearer 1, assisting the rising motion of the upper body of the wearer 1.

[0045] Fig. 9 shows an example of a motion in which a wearer 1 wearing an assist suit 10 equipped with a spine member 20, a waist attachment unit 40, and a foot attachment unit 30 bends forward as described in Fig. 7. By providing the foot attachment unit 30 in addition to the spine member 20 and the waist attachment unit 40, it is possible to further enhance the effect of assisting the wearer 1 in bending forward.

[0046] The assistance of the rising motion of the upper body of the wearer 1 by the spine member 20 and the waist mounting unit 40 in Fig. 9 is the same as that in Fig. 8, so a description thereof will be omitted. In Fig. 9, the foot belt 31 of the foot mounting unit 30 is connected to the waist mounting unit 40 and connected to the fixing member 32 of the knee of the wearer 1. In this state, when the wearer 1 bends forward, the foot belt 31 is stretched with the fixing member 32 as the starting point. When the foot belt 31 is stretched, a force that causes the foot belt 31 to contract with the fixing member 32 as the starting point acts on the connected waist mounting unit 40, so that a force that assists the rising motion of the wearer 1, who is bending forward with respect to the waist mounting unit 40, acts due to the stretching force of the foot belt 31 with the fixing member 32 as the starting point.

[0047] Furthermore, by connecting the foot belt 31 of the foot attachment part 30 to the first connecting part 41 via a third slit 43 provided in the first connecting part 41 for connecting the spine member 20 of the waist attachment part 40, the foot attachment part 30 is directly connected to the spine member 20 via the first connecting part 41, thereby further enhancing the effect of assisting the forward bending movement of the wearer 1.

[0048] 9 is made of a cylindrical member having elasticity for fixing to the left and right knees of the wearer 1, and is configured to tighten the upper and lower periphery of the wearer's knees. With this configuration, when the wearer bends forward and the foot belt 31 is stretched, the fixing member 32 is less likely to slip upward, and the effect of assisting the forward bending can be improved.

[0049] As described above, in the embodiment of the present invention, the spine member 20, which fits closely from the back to the buttocks of the wearer 1, achieves both posture correction for the wearer 1 and assists in bending forward. Furthermore, the shoulder belts 11 and waist belt 12 for fitting closely to the back of the wearer 1 are directly connected, so that it is possible to provide an assist suit 10 that is comfortable to wear and does not interfere with the work of the wearer, even when working in hot places in summer or for long periods of time.

[0050] Furthermore, if the assist suit 10 is configured to include, in addition to the spine member 20 and the waist attachment part 40, a foot attachment part 30 connected to the spine member 20 and the waist attachment part 40, it is possible to provide an assist suit 10 with an even higher assist effect.

[0051] <Example of the waist mounting section configuration> Another configuration example of the waist attachment part 40 will be described with reference to Figures 10 and 11. Figures 10 and 11 are diagrams showing a configuration example of the waist attachment part 40 including a tightening mechanism 50.

[0052] The waist attachment unit 40 in Fig. 10 includes a tightening mechanism 50 including a spool portion 51 arranged at a predetermined position on the waist attachment unit 40, a wire guide portion 52 arranged at a position facing the spool portion 51, and a wire portion 53 connecting the spool portion 51 and the wire guide portion 52. The tightening mechanism 50 is configured to tighten the waist of the wearer by winding up the wire portion 53 guided by the wire guide portion 52 with the waist attachment unit 40 attached to the wearer. By including such a tightening mechanism 50, the waist attachment unit 40 can be brought into closer contact with the wearer, thereby further enhancing the effect of assisting the wearer in bending forward.

[0053] As shown in Fig. 10, the spool portion 51 and the wire guide portion 52 may be disposed in opposing positions across the band portion 44 made of a material with higher flexibility than the other portions. With this configuration, the waist attachment portion 40 can be fitted more closely to the waist of the wearer according to the wearer's body shape. Also, as shown in Fig. 11, the wire guide portion 52 of the tightening mechanism 50 in Fig. 10 may be configured to include two wire guide portions (first wire guide portion, second wire guide portion) (52-1, 52-2), and another wire guide portion (third wire guide portion) (52-3) may be provided on the spool portion 51 side, so that the two wire guide portions (52-1, 52-2) are disposed in opposing positions to the spool portion 51 and the wire guide portion (52-3).
