[0010] ===This Embodiment=== <Configuration> FIG. 1 is a view of the assist suit 100 in a deployed state as seen from the outside. FIG. 2 is an explanatory view of a wearer wearing the assist suit 100 performing a pulling operation.

[0011] The assist suit 100 is a wearable device (assist suit for pulling operation) that assists in a pulling operation. The object of the pulling operation is, for example, a long object such as a rope, string, or chain. However, the object of the pulling operation is not limited to long objects and may also be a box, bag, etc. The assist suit 100 includes a waist belt 1 and a slide member 3. In addition, in the assist suit 100 of the present embodiment, an insertion member 20 having an insertion portion 2 is detachably provided on the waist belt 1.

[0012] In the following description, each part of the assist suit 100 may be described along the directions shown in FIGS. 1 and 2. As shown in FIG. 1, the right side of the wearer wearing the assist suit 100 is defined as "right", and the left side of the wearer is defined as "left", thereby defining the "left-right direction". In addition, the outside in the left-right direction may be referred to as the "outside in the left-right direction", and the inside in the left-right direction may be referred to as the "inside in the left-right direction". As shown in FIGS. 1 and 2, the upper side of the wearer wearing the assist suit 100 is defined as "up", and the opposite side is defined as "down", thereby defining the "up-down direction". Also, the direction perpendicular to the left-right direction and the up-down direction (the direction perpendicular to the paper surface of FIG. 1) is defined as the "thickness direction". When worn, the side close to the wearer's skin may be referred to as the "skin side" or "inside", and the opposite side may be referred to as the "non-skin side" or "outside". Also, the surface of the skin side (inside) may be referred to as the "skin side surface" or "inner surface", and the surface of the non-skin side (outside) may be referred to as the "non-skin side surface" or "outer surface". Further, as shown in FIG. 2, the front side of the wearer is defined as "front", and the opposite side is defined as "rear", thereby defining the "front-rear direction".

[0013] FIGS. 3A and 3B are views of the unfolded waist belt 1. FIG. 3A is a view of the waist belt 1 seen from the outside (non-skin side), and FIG. 3B is a view of the waist belt 1 seen from the inside (skin side). FIG. 4A is an explanatory diagram of the waist belt 1 during temporary fastening. FIG. 4B is an explanatory diagram of the waist belt 1 during final fastening. In FIGS. 3A and 3B and FIGS. 4A and 4B, the slide member 3 (and the insertion member 20) are not shown.

[0014] The waist belt 1 is a member that wraps around the waist. The waist belt 1 includes a main body belt 10 and a pair of auxiliary belts 18 (right auxiliary belt 18R and left auxiliary belt 18L). Note that the waist belt 1 may be composed of only the main body belt 10, and the waist belt 1 may not be provided with the auxiliary belt 18.

[0015] The main body belt 10 is a member that constitutes the main body of the waist belt 1. The main body belt 10 is a belt-shaped (band-shaped) member that wraps around the waist. The main body belt 10 may also be called the first belt. The main body belt 10 is configured in a substantially bilaterally symmetric shape. The main body belt 10 is composed of a central portion 11, a pair of intermediate portions 12 (right intermediate portion 12R and left intermediate portion 12L), and a pair of end portions 13 (right end portion 13R and left end portion 13L).

[0016] The central portion 11 is a portion that is worn around the waist. When the wearer wears the waist belt 1, the central portion 11 will be arranged on the back side of the wearer. The central portion 11 is arranged at the center in the left-right direction of the main body belt 10. As shown in FIG. 1, an insertion portion 2 is provided in the central portion 11. A hook-and-loop fastener 11A is provided on the outer surface (non-skin side surface) of the central portion 11. The hook-and-loop fastener 11A is a member that removably fixes an insertion member 20 having the insertion portion 2. The central portion 11 is composed of a non-elastic member. The central portion 11 is configured to be wider than the end portions 13 (right end portion 13R and left end portion 13L).

[0017] The intermediate portion 12 is a portion that is arranged outside the central portion 11 in the left-right direction. The right intermediate portion 12R is provided on the right side of the central portion 11, and the left intermediate portion 12L is provided on the left side of the central portion 11. The intermediate portion 12 is arranged between the central portion 11 and the end portion 13. The intermediate portion 12 is composed of an elastic member. However, the intermediate portion 12 may be composed of a non-elastic member. By configuring the intermediate portion 12 as an elastic member, it becomes easier to wear the main body belt 10 around the waist.

[0018] The upper edge of the middle part 12 is configured to be substantially parallel to the left - right direction, while the lower edge of the middle part 12 is inclined so as to be higher toward the outer side in the left - right direction. For this reason, the middle part 12 is configured such that the width (dimension in the up - down direction) is thicker the closer it is to the central part 11 and narrower the closer it is to the end part 13.

[0019] A first connecting part 15 is provided between the central part 11 and the middle part 12. The first connecting part 15 is a part (connecting part) that connects the central part 11 and the middle part 12. Also, the first connecting part 15 has a function of connecting the end of the auxiliary belt 18 to the main body belt 10. The first connecting part 15 is arranged adjacent to the right - left outer side of the hook - and - loop fastener 11A of the central part 11.

[0020] The end part 13 is a part arranged more on the outer side in the left - right direction than the middle part 12. A right end part 13R is provided at the right end of the main body belt 10, and a left end part 13L is provided at the left end of the main body belt 10. A right end part 13R is provided on the right side of the right middle part 12R, and a left end part 13L is provided on the left side of the left middle part 12L. The end part 13 (right end part 13R and left end part 13L) is configured in a strip shape that is narrower than the central part 11. The end part 13 (right end part 13R and left end part 13L) is composed of a non - stretchable member.

[0021] A male - side hook - and - loop fastener 14A is provided on the inner surface (skin - side surface) of the right end part 13R, and a female - side hook - and - loop fastener 14B is provided on the outer surface (non - skin - side surface) of the left end part 13L. By engaging the hook - and - loop fastener 14A (male) of the right end part 13R and the hook - and - loop fastener 14B (female) of the left end part 13L, as shown in Fig. 4A, the main body belt 10 can be worn around the waist. Note that a female - side surface fastener 14B is also provided on the outer surface (non - muscle side surface) of the right end portion 13R. The surface fastener 14B on the outer surface of the end portion 13 (right end portion 13R and left end portion 13L) has a function of fixing the surface fastener 19 provided at the end of the auxiliary belt 18. The surface fastener 14B of the left end portion 13L has a function of fixing the surface fastener 14A provided inside the right end portion 13R and a function of fixing the surface fastener 19 provided at the end of the auxiliary belt 18 (left auxiliary belt 18L).

[0022] The end portion 13 is configured to be inclined such that it is higher on the outer side in the left - right direction. For this reason, the tips of the end portion 13 (the right end of the right end portion 13R and the left end of the left end portion 13L) are provided above the central portion 11. By configuring the end portion 13 to be inclined, the main body belt 10 is configured to conform to the shape of the wearer's waist constriction (to conform to the shape of the human body above the pelvis), and a structure that allows the main body belt 10 to be easily adhered to the wearer's body can be achieved.

[0023] A second connecting portion 16 is provided between the intermediate portion 12 and the end portion 13. The second connecting portion 16 is a portion (connecting portion) that connects the intermediate portion 12 and the end portion 13.

[0024] The auxiliary belts 18 (right auxiliary belt 18R and left auxiliary belt 18L) are members that assist in wearing the main body belt 10 around the waist. The auxiliary belt 18 is a belt-shaped (band-shaped) member provided on the outer side (non-skin side) of the main body belt 10 and has a function of tightening the main body belt 10 around the waist. The auxiliary belt 18 may also be called the second belt. The right auxiliary belt 18R is provided on the right side of the main body belt 10, and the left auxiliary belt 18L is provided on the left side of the main body belt 10. One end (base end; the end on the inner side in the left-right direction) of the auxiliary belt 18 is connected to the first connecting portion 15. A hook-and-loop fastener 19 is provided on the inner surface (skin side surface) of the other end (free end; the end on the outer side in the left-right direction) of the auxiliary belt 18. As shown in FIG. 4B, the free end of the auxiliary belt 18 can be detachably fixed to the hook-and-loop fastener 14B on the outer surface (non-skin side surface) of the end portion 13 (right end portion 13R and left end portion 13L) of the main body belt 10. The hook-and-loop fastener 19 of the right auxiliary belt 18R is fixed to the hook-and-loop fastener 14B outside the right end portion 13R, and the hook-and-loop fastener 19 of the left auxiliary belt 18L is fixed to the hook-and-loop fastener 14B outside the left end portion 13L. Note that the auxiliary belt 18 may not be provided on the waist belt 1.

[0025] The auxiliary belt 18 is configured to be inclined such that the outer side in the left-right direction is higher. As already described, since the end portion is configured to be inclined such that the outer side in the left-right direction is higher, by configuring the auxiliary belt 18 to be inclined such that the outer side in the left-right direction is higher, the structure becomes such that it is easy to fix the hook-and-loop fastener 19 of the auxiliary belt 18 to the hook-and-loop fastener 14B of the end portion 13.

[0026] As shown in FIG. 1, the waist belt 1 has an insertion portion 2. The insertion portion 2 is a portion through which the arm belt 40 is inserted. The insertion portion 2 is configured in a ring shape. The insertion portion 2 is provided at the central portion 11 of the waist belt 1. In other words, the insertion portion 2 is provided at the center in the left - right direction of the waist belt 1. When the wearer wears the waist belt 1, the insertion portion 2 will be disposed on the back side of the wearer. Thereby, it becomes possible to apply a pulling force to the waist (pelvis) during the pulling operation. Also, the insertion portion 2 slidably holds the arm belt 40 with respect to the waist belt 1. Thereby, it becomes possible to extend forward the hand of the wearer's preference, either the right hand or the left hand. Also, it becomes possible to alternately extend the left and right hands forward, and it becomes possible to perform an operation of winding a long object (winding operation). In the present embodiment, the insertion portion 2 is provided on the insertion member 20. The insertion member 20 will be described later.

[0027] FIG. 5 is an explanatory view of the slide member 3 and the insertion member 20.

[0028] The slide member 3 is a member that can slide in the left - right direction with respect to the waist belt 1. The slide member 3 has a pair of mounting portions 30 (right mounting portion 30R and left mounting portion 30L) and the arm belt 40.

[0029] The mounting portion 30 is a member to be mounted on the hand. The right mounting portion 30R is provided on the right side of the slide member 3, and the left mounting portion 30L is provided on the left side of the slide member 3. The right mounting portion 30R is mounted on the right hand, and the left mounting portion 30L is mounted on the left hand. The pair of mounting portions 30 (right mounting portion 30R and left mounting portion 30L) are provided at both ends of the arm belt 40.

[0030] FIGS. 6A and 6B are explanatory views of the mounting portion 30 (right mounting portion 30R). FIG. 6A is an explanatory view of the mounting portion 30 as seen from the back of the hand side. FIG. 6B is an explanatory view of the mounting portion 30 as seen from the palm side of the hand.

[0031] The wearing part 30 is composed of a glove. By configuring the wearing part 30 with a glove, it becomes easier for the wearer to grasp an object (e.g., a rope), and it is possible to suppress the object from slipping. The wearing part 30 in the figure is composed of a fingerless type glove (open finger glove). However, the wearing part 30 does not have to be a fingerless type glove, and it may be a full finger type glove. Also, the wearing part 30 does not have to be a glove, and it may be an annular member that can be hooked between the thumb and the index finger.

[0032] The wearing part 30 has a fastener 31. By providing the fastener 31 on the wearing part 30, the wearing comfort can be improved, and it is possible to suppress the wearing part 30 from coming off the hand during a pulling operation. However, the wearing part 30 does not have to be provided with the fastener 31.

[0033] The wearing part 30 has an attachment part 32 for attaching the arm belt 40. Here, the attachment part 32 is composed of a fabric to which a fastener 41 (buckle; see Fig. 5) is attached. The attachment part 32 is provided on the palm side of the wearing part 30. Specifically, the fabric constituting the attachment part 32 is sewn to the fabric on the palm side of the wearing part 30. As a result, a structure is formed in which the arm belt 40 is connected to the fabric on the palm side of the wearing part 30. By providing the attachment part 32 on the palm side, the tension from the arm belt 40 is transmitted to the fabric on the palm side of the wearing part 30, so that it is easier to grasp an object (e.g., a rope) during a pulling operation than when the attachment part 32 is provided on the back side of the hand.

[0034] It is desirable that the fabric on the palm side of the wearing part 30 is provided with an anti-slip treatment. Thereby, it is possible to suppress the object from slipping during a pulling operation.

[0035] The arm belt 40 is a belt-like member that connects a pair of wearing parts 30 (see Fig. 5). The wearing parts 30 are provided at both ends of the arm belt 40. The arm belt 40 is composed of a non-stretchable member. The arm belt 40 is provided so as to be slidable in the left-right direction with respect to the main body belt 10.

[0036] The wrist belt 40 is provided with a fastener 41. The wrist belt 40 and the mounting part 30 are detachably connected via the fastener 41. By providing the fastener 41 between the wrist belt 40 and the mounting part 30, the mounting part 30 can be attached to and detached from the wrist belt 40, making it easier to wear the mounting part 30 by hand. However, the wrist belt 40 and the mounting part 30 may be directly connected. For example, the end of the wrist belt 40 may be directly sewn to the mounting part 32 of the mounting part 30. As already described, the fastener 41 is attached to the mounting part 32 on the palm side of the mounting part 30. Thereby, since the tension from the wrist belt 40 is transmitted to the fabric on the palm side of the mounting part 30, it becomes a structure that is easy to grip an object (for example, a rope) during the pulling operation.

[0037] The wrist belt 40 has an adjustment part 42. The adjustment part 42 is a member for adjusting the length of the wrist belt 40. By means of the adjustment part 42, the wrist belt 40 can be set to a length suitable for the build of the wearer. Here, the wrist belt 40 is provided with a pair of adjustment parts 42. One adjustment part 42 is provided on the right side of the wrist belt 40, and the other adjustment part 42 is provided on the left side of the wrist belt 40. In this way, by providing the adjustment parts 42 on the left and right sides of the wrist belt 40 respectively, it becomes a structure that makes it easy to adjust the length of the wrist belt 40 according to each of the left and right arms. However, there may be one adjustment part 42 provided on the wrist belt 40. Even in the case where there is one adjustment part 42, by sliding the wrist belt 40 in the left - right direction, it is possible to adjust the length of the wrist belt 40 according to each of the left and right arms.

[0038] The wrist belt 40 is inserted into the insertion part 2 provided on the waist belt 1. By being inserted into the insertion part 2, the wrist belt 40 is held slidably in the left - right direction with respect to the waist belt 1. When the wrist belt 40 is inserted into the insertion part 2 of the waist belt 1, the wrist belt 40 will be arranged around the wearer's back waist when the assist suit 100 is worn (see Fig. 2). Thus, during the pulling operation, a force is applied to the waist (pelvis) by the wrist belt 40, and the wearer's waist can function like a pulley. The insertion part 2 is provided on an insertion member 20 that is detachable from the waist belt 1.

[0039] The insertion member 20 is a member provided with the insertion part 2. A hook - and - loop fastener (not shown) is provided on the inner surface of the insertion member 20 (the surface on the waist - belt 1 side; the skin - side surface). The hook - and - loop fastener of the insertion member 20 is a member that can be detachably fixed to the hook - and - loop fastener 11A at the central part 11 of the waist belt 1. That is, the insertion member 20 is configured to be detachable from the waist belt 1. Thereby, the vertical position of the insertion member 20 with respect to the waist belt 1 can be changed.

[0040] Figs. 7A and 7B are explanatory diagrams of the change in the arrangement of the insertion member 20.

[0041] By changing the vertical position of the insertion member 20 with respect to the waist belt 1, the vertical position of the insertion part 2 can be changed. Since the insertion part 2 is the position where a force is applied to the waist during the pulling operation, by changing the vertical position of the insertion member 20, the position where the force is applied during the pulling operation can be adjusted. Note that, in order to have a structure in which the vertical position of the insertion member 20 with respect to the waist belt 1 can be changed, the vertical dimension of the insertion member 20 is shorter than the vertical dimension of the hook - and - loop fastener 11A at the central part 11 of the waist belt 1.

[0042] Note that the insertion part 2 may not be provided on the insertion member 20. For example, the insertion part 2 may be directly provided at the central part 11 of the waist belt 1. When the insertion part 2 is directly provided on the waist belt 1, the assist suit 100 may not include the insertion member 20. However, in this case, the structure cannot adjust the position where the force is applied during the pulling operation.

[0043] <Regarding the use of the assist suit 100> ·Wearing the assist suit 100 When wearing the assist suit 100, as shown in Fig. 4A, the wearer wraps the main body belt 10 around the waist while pressing the central part 11 of the main body belt 10 against the waist, and engages the hook-and-loop fastener 14A (male) on the right end part 13R and the hook-and-loop fastener 14B (female) on the left end part 13L to wear the main body belt 10 around the waist (temporarily fasten). After wearing the main body belt 10 around the waist, as shown in Fig. 4B, the wearer fixes the hook-and-loop fastener 19 of the auxiliary belt 18 to the hook-and-loop fastener 14B of the main body belt 10 and tightens the main body belt 10 around the waist (finally fasten). By tightening the main body belt 10 around the waist using the auxiliary belt 18, the wearing comfort of the waist belt 1 can be improved.

[0044] Also, the wearer wears the wearing part 30 on both hands. In the case of a structure where the wearing part 30 and the arm belt 40 are connected by the fastener 41, after wearing the wearing part 30 in the state of being detached from the arm belt 40 on the hand, the wearing part 30 and the arm belt 40 can be connected by the fastener 41, so it is easier to wear the wearing part 30 on the hand. However, the wearing part 30 in the state of being connected to the arm belt 40 may also be worn on the hand.

[0045] The wearer may adjust the vertical position of the insertion part 2. When the position of the insertion part 2 is too high or too low, the wearer temporarily removes the insertion member 20 from the waist belt 1 and adjusts the vertical position of the insertion member 20 relative to the waist belt 1. Note that the adjustment of the position of the insertion part 2 may be performed before or after wearing the waist belt 1 or the wearing part 30.

[0046] The wearer may adjust the length of the arm belt 40. If the arm belt 40 is too long, it becomes difficult for tension to act on the arm belt 40 during the pulling operation, making it difficult to assist the pulling operation. On the other hand, if the arm belt 40 is too short, it becomes difficult for the wearer to operate the object (e.g., a rope). Therefore, it is desirable for the wearer to use the adjustment unit 42 to adjust the length of the arm belt 40 to a length suitable for the pulling operation. The adjustment of the length of the arm belt 40 may be performed before or after wearing the waist belt 1 or the wearing part 30.

[0047] ·Pulling operation As shown in FIG. 2, the wearer wearing the assist suit 100 will pull an object such as a rope. When the assist suit 100 is worn, the insertion part 2 is arranged on the back side of the wearer, and the arm belt 40 is arranged around the waist on the back side of the wearer. As a result, during the pulling operation, force is applied to the waist (pelvis) by the arm belt 40, and the wearer's waist can function like a pulley. In FIG. 2, the wearer is performing a pulling operation with the right hand forward. However, since the arm belt 40 is configured to be slidable relative to the waist belt 1, it is also possible to perform a pulling operation with the left hand forward.

[0048] FIG. 8A is an explanatory diagram of the body load during the pulling operation when the assist suit 100 is used. FIG. 8B is an explanatory diagram of the body load during the pulling operation when the assist suit 100 is not used.

[0049] In FIG. 8B, Wub is the mass of the upper body (above the waist). Wul is the mass of the arm (upper limb; from the shoulder to the tip). L1 is the horizontal distance from the waist rotation center to the center of gravity of the upper body. L2 is the vertical distance from the waist rotation center to the handle. L3 is the horizontal distance from the shoulder rotation center to the center of gravity of the arm. Lul is the length of the arm (the distance from the shoulder rotation center to the handle). θ is the angle formed by the vertical line and the arm. F is the frictional force (pulling force) received by the hand from the rope. Ml is the joint moment due to the muscle strength around the waist during the pulling operation. Ms is the joint moment due to the muscle strength around the shoulder during the pulling operation.

[0050] As shown in FIG. 8B, the waist joint moment Ml and the shoulder joint moment Ms can be expressed as follows (where g in the following formula is the gravitational acceleration). Ml = Wub × g × L1 + F × L2 Ms = F × Lul × cosθ - Wul × g × L3

[0051] As shown in FIG. 8A, when the assist suit 100 is used, the force F (tensile force) received from the rope by the arm belt 40 is applied to the waist (pelvis). Therefore, the waist joint moment Ml is only the force (Wub × g × L1) generated by the mass Wub of the upper body. Note that when the assist suit 100 is not used as shown in FIG. 8B, the state is to pull the rope with the "arm", whereas when the assist suit 100 is used as shown in FIG. 8A, the state is to pull the rope with the "waist", and the rope can be pulled by tilting the whole body backward. Thus, by using the assist suit 100, the load on the waist during the pulling operation can be reduced as compared with the case where the assist suit 100 is not used.

[0052] L1 Also, as shown in FIG. 8A, since the arm belt 40 fixes the waist and the hand, the part from the waist to the hand can be regarded as a substantially rigid body. Therefore, by using the assist suit 100, the shoulder joint moment Ms can be suppressed, and the load on the shoulder during the pulling operation can be reduced.

[0053] · Hand reeling operation FIGS. 9A and 9B are explanatory diagrams of the state where the arm belt 40 slides. FIG. 9A is an explanatory diagram of the state where the left hand is extended in front of the right hand. FIG. 9B is an explanatory diagram of the state where the right hand is extended in front of the left hand.

[0054] When pulling a long object like a rope, it is sometimes necessary to stretch the long object before the pulling operation, so the long object may be wound by hand. In the assist suit 100 of the present embodiment, since the arm belt 40 is configured to be slidable with respect to the waist belt 1, it is possible to alternately extend the left and right hands forward, and it is possible to perform an operation of winding the long object (winding operation). In addition, even when one hand is extended to grasp or pick up an object before the pulling operation, since the arm belt 40 is configured to be slidable with respect to the waist belt 1, the work becomes easier.

[0055] <Parentheses> The assist suit 100 for the pulling operation described above includes a waist belt 1 wound around the waist, a pair of mounting parts 30 worn on the hands, and an arm belt 40 connecting the pair of mounting parts 30. The waist belt 1 has an insertion part 2, and the arm belt 40 is inserted into the insertion part 2. Since the arm belt 40 extends left and right from the insertion part 2 of the waist belt 1, as shown in FIGS. 2 and 8A, when performing a pulling operation, the pulling force is applied to the waist (pelvis) by the arm belt 40, so that the load on the wearer can be reduced and the pulling operation can be assisted. In addition, since the arm belt 40 is inserted into the insertion part 2, it is possible to perform a pulling operation with the hand preferred by the wearer of the right hand or the left hand facing forward. In addition, since the arm belt 40 is inserted into the insertion part 2, as shown in FIGS. 9A and 9B, the arm belt 40 can be configured to be slidable with respect to the waist belt 1, and the winding operation becomes easier.

[0056] As shown in FIGS. 7A and 7B, the insertion part 2 is configured to be able to adjust the vertical position. Thereby, the position of the force applied to the waist (pelvis) during the pulling operation can be adjusted.

[0057] Also, as shown in FIGS. 7A and 7B, the waist belt 1 has a hook-and-loop fastener 11A, and the insertion part 2 is provided on an insertion member 20 that can be attached to and detached from the hook-and-loop fastener 11A of the waist belt 1. Thereby, the insertion part 2 can be configured to be position-adjustable.
