[0003] [Patent Document 1] Patent No. 6503115 Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure discloses an example of an assist suit that can effectively assist the wearer. [Means for solving the problem]

[0005] An assist suit for reducing the workload of the wearer desirably has at least one of the following constituent features, for example:

[0006] That is, the constituent elements preferably include a waist belt (9) that is wrapped around the waist of the wearer and attached to the waist, elastic members (6, 7) one end of which is connected to the back side of the waist belt (9) and the other end of which extends towards the shoulders of the wearer, and a buttocks belt (10) that is wrapped around the gluteal groove of the wearer and attached to the buttocks, and which is connected to the back side of the waist belt (9).This increases the adhesion between the lower ends of the elastic members (6, 7), i.e., the elastic members (6, 7) and the waist belt (9), and the body, so that the assist suit can effectively assist the wearer.

[0007] The elastic bodies (6, 7) and the buttocks belt (10) of the assist suit are preferably connected to a resin back plate (9D) provided on the back side of the waist belt (9). This ensures increased adhesion, making it possible to effectively assist the wearer.

[0008] Another assist suit is provided with a waist belt (9) that is wrapped around the waist of the wearer and attached to the waist, a first elastic body (6) in the form of a strip spring, one end of which is connected to the back side of the waist belt (9) and the other end of which extends towards the shoulders of the wearer, and a second elastic body (7) in the form of a strip spring, one end of which is connected to the back side of the waist belt (9) and the other end of which extends towards the shoulders of the wearer, and the second elastic body (7) passes through the center of the back side of the waist belt (9) and is attached to the waist belt (9). When an imaginary line perpendicular to the longitudinal direction is defined as the center line (Lo), the connection between the first elastic body (6) and the waist belt (9) is defined as the first waist connection part (J1), and the connection between the second elastic body (7) and the waist belt (9) is defined as the second waist connection part (J2), the first waist connection part (J1) is located on the opposite side of the center line (Lo) from the second waist connection part (J2), and further, the first elastic body (6) and the second elastic body (7) intersect at a position on the other end side of the waist belt (9), extend toward the wearer's shoulders, and are arranged in a roughly X-shape.

[0009] In this assist suit, the two elastic bodies (6, 7) cross at a position on the other end side of the waist belt (9) and extend toward the shoulders of the wearer, forming a roughly X-shape, so that the suit can effectively assist the wearer even when the wearer twists when returning to a standing position from a bent-over or seated position.

[0010] Furthermore, it is desirable that the assist suit be connected at the intersection of the first elastic body (6) and the second elastic body (7), which allows the assist suit to provide a large assist force to the wearer.

[0011] Furthermore, it is desirable that the dimension (L11) from the other end of the first elastic body (6) to the intersection is greater than the dimension (L21) from one end of the first elastic body (6) to the intersection, and that the dimension (L12) from the other end of the second elastic body (7) to the intersection is greater than the dimension (L22) from one end of the second elastic body (7) to the intersection. The intersection refers to the area where the first elastic body (6) and the second elastic body (7) intersect.

[0012] This allows the assist suit to provide a large assist force to the wearer.

[0013] In addition, in other assist suits, it is desirable to have a waist belt (9) that is wrapped around the waist of the wearer and attached to the waist, elastic members (6, 7) one end of which is connected to the back side of the waist belt (9) and the other end of which extends toward the shoulders of the wearer, and a regulation belt (8) that is provided at a position on the other end side of the waist belt (9) and crosses the back side of the wearer, and that regulates the elastic members (6, 7) from moving away from the back of the wearer. This increases the adhesion between the elastic members (6, 7) and the wearer, so that the assist suit can effectively assist the wearer.

[0014] The assist suit is preferably provided with shoulder belts (4, 5) directly or indirectly connected to the other ends of the elastic bodies (6, 7), and the shoulder belts (4, 5) are preferably connectable to a restraining belt (8) on the chest side of the wearer, thereby enabling more effective support for the wearer.

[0015] It is also desirable to provide a connecting portion (J4) that connects the regulating belt (8) and the elastic bodies (6, 7) on the back side of the wearer, which increases the adhesion between the elastic bodies (6, 7) and the wearer, allowing the assist suit to effectively assist the wearer.

[0018] The following "embodiments of the invention" are examples of embodiments that fall within the technical scope of the present disclosure. In other words, the invention-specific matters described in the claims are not limited to the specific configurations and structures shown in the following embodiments.

[0019] Note that arrows and diagonal lines indicating directions in each figure are provided to facilitate understanding of the relationship between the figures and the shapes of each component or part. Therefore, the invention disclosed in this disclosure is not limited to the directions indicated in each figure. Diagonal lines do not necessarily indicate cross-sectional views.

[0020] At least one of each member or part that is described with a symbol is provided, unless otherwise specified, such as "one." In other words, unless otherwise specified, such as "one," two or more members may be provided. The assist suit disclosed in this disclosure includes at least the components, such as the members or parts, that are described with a symbol, as well as the structural parts shown in the drawings.

[0021] (First embodiment) <1. Overview of the assist suit> In this embodiment, an example of the present disclosure is applied to an assist suit in the shape of a vest (also called a "waistcoat," "gilet," or "waistcoat," etc.). FIG. 1 is a front view of the assist suit 1 according to this embodiment. FIG. 2 is a back view of the assist suit 1.

[0022] <1.1 Components of the Assist Suit> As shown in Figures 1 and 2, the assist suit 1 comprises at least a front body 2, a back body 3, a right shoulder belt 4, a left shoulder belt 5, a first elastic body 6, a second elastic body 7, a regulating belt 8, a waist belt 9, a buttocks belt 10, and a back pad 11.

[0023] <1.2 Clothing section> The garment part 12 is a vest-like garment and is made up of a front body part 2 and a back body part 3. In other words, the front body part 2 and the back body part 3 are the fabrics that make up the garment part 12.

[0024] Specifically, the front body 2 is a fabric that covers the shoulders, chest, and underarms of the wearer. The front body 2 is composed of a front body 2 on the right shoulder side and a front body 2 on the left shoulder side. The back body 3 is a fabric that covers the back of the wearer, that is, the back area from the shoulders to the waist. The front body 2 on the right shoulder side and the front body 2 on the left shoulder side can be connected by a connecting strap 2E.

[0025] <1.3 Waist belt> The waist belt 9 is a part that is wrapped around the waist of the wearer and attached to the waist (see FIG. 5). The waist belt 9 has a first waist belt 9A and a second waist belt 9B. The second waist belt 9B is a belt that is wrapped around the outer circumference of the first waist belt 9A.

[0026] As shown in Fig. 3, the first waist belt 9A is made of a single piece of fabric together with the back body 3. The portion of the first waist belt 9A that corresponds to the waist (the shaded area in Fig. 3) is made of fabric that has a high coefficient of friction and is not slippery (so-called grip fabric).

[0027] The first waist belt 9A is provided with a surface fastener (not shown) at one end and the other end in the extension direction (the right end and the left end of the first waist belt 9A in FIG. 3). As shown in FIG. 4, a tunnel portion 9C is provided on the back surface of the first waist belt 9A.

[0028] The tunnel portion 9C is a flat through-hole extending in the left-right direction through which the second waist belt 9B is inserted. The second waist belt 9B is a flat belt that is wound around the first waist belt 9A from the outside so as to overlap it.

[0029] The second waist belt 9B is a belt that is narrower than the first waist belt 9A. The first waist belt 9A is a belt that is intended to be worn so as to cover the entire waist and lower abdomen. The second waist belt 9B is a belt that is intended to be worn below the iliac crest.

[0030] <1.4 First elastic body, second elastic body> 4, the first elastic body 6 and the second elastic body 7 are strip-shaped springs having one end connected to the back side of the waist belt 9 and the other end extending toward the shoulders of the wearer. Incidentally, the first elastic body 6 and the second elastic body 7 according to this embodiment are made of carbon fiber reinforced plastic.

[0031] One end side (lower end side in FIG. 4) of the first elastic body 6 and the second elastic body 7 is connected and fixed to the waist belt 9 together with a resin back plate 9D. The back plate 9D is a member with higher rigidity than the waist belt 9, and is a plate located approximately in the center of the back side of the waist belt 9 (in this embodiment, the first waist belt 9A).

[0032] Specifically, the first waist belt 9A is provided with a bag portion (not shown) into which a back plate 9D is inserted. The lower ends of the first elastic body 6 and the second elastic body 7, together with the back plate 9D, are connected and fixed to the first waist belt 9A by a connecting device C. The connecting device C is, for example, an eyelet or a bolt.

[0033] When the imaginary line that passes through the center of the back side of the waist belt 9 and is perpendicular to the longitudinal direction of the waist belt 9 is defined as the center line Lo, as shown in Figure 4, the first waist connector J1 is located on the opposite side of the center line Lo from the second waist connector J2.

[0034] Specifically, the first waist connector J1 is located on the left side of the center line Lo, and the second waist connector J2 is located on the right side of the center line Lo. The first waist connector J1 refers to the connector between the first elastic body 6 and the waist belt 9. The second waist connector J2 refers to the connector between the second elastic body 7 and the waist belt 9.

[0035] Furthermore, the first elastic body 6 and the second elastic body 7 intersect at a position on the other end side of the waist belt 9 (above the waist belt 9 in FIG. 4) and extend toward the shoulders of the wearer, forming a generally X-shaped configuration. Specifically, the first elastic body 6 is inclined upward to the right, and the second elastic body 7 is inclined upward to the left.

[0036] The upper end of the first elastic body 6 is connected to the back body 3 near the right shoulder by a connector C. Similarly, the upper end of the second elastic body 7 is connected to the back body 3 near the left shoulder by a connector C.

[0037] A connecting portion J3 is provided at the location where the first elastic body 6 and the second elastic body 7 intersect. The connecting portion J3 is the location where the first elastic body 6 and the second elastic body 7 are connected by a connector C. The first elastic body 6 and the second elastic body 7 are housed in a pouch portion 3A provided in the back body 3.

[0038] Furthermore, when the location where the first elastic body 6 and the second elastic body 7 intersect is defined as the intersection, as shown in FIG. 2, the dimension L11 from the upper end of the first elastic body 6 to the intersection is greater than the dimension L21 from the lower end of the first elastic body 6 to the intersection.

[0039] Similarly, the dimension L12 from the upper end of the second elastic body 7 to the intersection is greater than the dimension L22 from the lower end of the second elastic body 7 to the intersection. The position of the intersection is the point where the center line of the first elastic body 6 and the center line of the second elastic body 7 intersect.

[0040] <1.5 Shoulder belts, restraint belts> As shown in Fig. 1, the shoulder belts 4, 5 are belts directly or indirectly connected to the upper ends of the two elastic bodies 6, 7. Specifically, as shown in Fig. 2, the right shoulder belt 4 is connected to the back body 3 at the upper end of the first elastic body 6 by a connector C.

[0041] The left shoulder belt 5 is connected to the back body 3 at the upper end side of the second elastic body 7 by a connector C. The positions of the shoulder belts 4, 5 are maintained by loops 2A to 2D (see Figs. 1 and 2). The loops 2A to 2D cooperate with the front body 2 to form flat rings through which the shoulder belts 4, 5 pass.

[0042] As shown in Figure 2, the regulation belt 8 is located above the waist belt 9 and is a belt that crosses the back side of the wearer, and is a belt that regulates the two elastic bodies 6 and 7 from moving away from the back of the wearer.

[0043] Specifically, the regulating belt 8 is positioned so as to cross the back side of the wearer at a position on the back corresponding to the armpits or the chest, and is connected to two elastic bodies 6 and 7 at that position.

[0044] That is, the regulation belt 8 is connected to the two elastic bodies 6, 7 together with the back piece 3 at the connecting portion J4. Specifically, the regulation belt 8, the back piece 3, and the two elastic bodies 6, 7 are connected by a connector C at the connecting portion J4.

[0045] As shown in Fig. 1, one longitudinal end (right end) 8A of the regulation belt 8 wraps around the chest. Similarly, the other longitudinal end (left end) 8B of the regulation belt 8 wraps around the chest. The right shoulder belt 4 can be connected to the right end 8A of the regulation belt 8 on the chest side of the wearer. The left shoulder belt 5 can be connected to the left end 8B of the regulation belt 8 on the chest side of the wearer.

[0046] <1.6 Buttocks Belt> The hip belt 10 is a belt that is wrapped around the gluteal crease of the wearer and worn on the buttocks, as shown in Figures 5 to 8. The hip belt 10 is connected to the back side of the waist belt 9, as shown in Figure 2.

[0047] Specifically, the buttocks belt 10 is connected to the back plate 9D via a connecting belt 10A. The connecting belt 10A is a flat belt inserted into a through-hole (not shown) provided in the back plate 9D.

[0048] At least one (two in this embodiment) hanging ring 10B is provided on the waist belt 9. The two hanging rings 10B have loop portions 10C into which the hip belt 10 can be inserted. The hanging rings 10B are provided at positions symmetrical to the left and right of the connecting belt 10A.

[0049] <1.7 Back Pad> The back pad 11 is intended to fill the gap that occurs between the back body 3 and the back of the wearer, as shown in Fig. 9. The back pad 11 is fixed to a pad belt 11A, as shown in Fig. 1.

[0050] The pad belt 11A can be wrapped around the back body 3. Therefore, the wearer can move the pad belt 11A relative to the back body 3 so that the back pad 11 is in an appropriate position.

[0051] Incidentally, the human spine is curved in an S-shape. In contrast, the first elastic body 6 and the second elastic body 7 are not curved in an S-shape. Incidentally, the first elastic body 6 and the second elastic body 7 according to this embodiment are in the shape of a substantially straight strip when not deformed.

[0052] For this reason, when the wearer is wearing the assist suit, a large gap occurs between the back body 3 and the back of the wearer (see Figure 9). The back pad 11 is a pad designed to fill this gap.

[0053] <2. How to use the assist suit according to this embodiment> After putting on the garment part 12, the wearer adjusts the shoulder belts 4, 5, waist belt 9, regulation belt 8, and hip belt 10 so that they are in close contact with the body. At this time, it is desirable that the regulation belt 8 and the shoulder belts 4, 5 are connected so that the regulation belt 8 is positioned under the armpits (see Figure 10).

[0054] The buttocks belt 10 is preferably worn so as to be positioned between the gluteal crease and the crotch of the wearer (see Figs. 5 to 7). The position of the pad belt 11A of the back pad 11 is preferably adjusted so that it is positioned in the gap between the back body 3 and the back of the wearer (see Fig. 9).

[0055] <3. Features of the assist suit according to this embodiment> In the assist suit 1 of this embodiment, the two elastic bodies 6, 7 cross at a position above the waist belt 9 and extend toward the shoulders of the wearer, arranging them in an approximately X-shape, so that the suit can effectively assist the wearer even when the wearer twists when recovering from a bent-over or seated position to a standing position.

[0056] The assist suit 1 is connected at the intersection of the first elastic body 6 and the second elastic body 7. This makes it possible for the assist suit 1 to provide a large assist force to the wearer.

[0057] The dimension L11 from the upper end of the first elastic body 6 to the intersection is larger than the dimension L21 from the lower end of the first elastic body 6 to the intersection, and the dimension L12 from the upper end of the second elastic body 7 to the intersection is larger than the dimension L22 from the lower end of the second elastic body 7 to the intersection. This makes it possible for the assist suit 1 to provide a large assist force to the wearer.

[0058] The assist suit 1 is equipped with a restriction belt 8 that restricts the two elastic bodies 6, 7 from moving away from the back of the wearer. This increases the adhesion between the two elastic bodies 6, 7 and the wearer, allowing the assist suit 1 to effectively assist the wearer.

[0059] The assist suit 1 is equipped with shoulder belts 4, 5 connected directly or indirectly to the upper ends of two elastic bodies 6, 7, and the shoulder belts 4, 5 can be connected to a regulation belt 8 on the chest side of the wearer. This makes it possible to more effectively assist the wearer.

[0060] The regulation belt 8 is connected to the two elastic bodies 6, 7 on the back side of the wearer. This increases the adhesion between the two elastic bodies 6, 7 and the wearer, allowing the assist suit 1 to effectively assist the wearer.

[0061] The assist suit 1 is also equipped with a buttocks belt 10 that is wrapped around the gluteal crease of the wearer and attached to the buttocks, and is connected to the back side of the waist belt 9. This increases the adhesion between the lower ends of the two elastic bodies 6, 7, i.e., the elastic bodies 6, 7 and the waist belt 9, and the body, allowing the assist suit 1 to effectively assist the wearer.

[0062] The two elastic bodies 6, 7 and the buttocks belt 10 are connected to a resin back plate 9D provided on the back side of the waist belt 9. This ensures increased adhesion, making it possible to effectively support the wearer.

[0063] (Other embodiments) In the above-described embodiment, the two elastic bodies 6 and 7 are arranged in an X-shape. However, the present disclosure is not limited to this. That is, the present disclosure may be, for example, a configuration in which the two elastic bodies 6 and 7 are arranged parallel to each other or in a V-shape, or a configuration in which one strip-shaped elastic body is arranged along the spine (imaginary line Lo).

[0064] In the above-described embodiment, the first elastic body 6 and the second elastic body 7 are connected at an intersection. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that the first elastic body 6 and the second elastic body 7 are not connected at an intersection.

[0065] In the above-described embodiment, the dimension L11 is greater than the dimension L21 and the dimension L12 is greater than the dimension L22. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that, for example, the dimension L11 = the dimension L21 and the dimension L12 = the dimension L22.

[0066] In the above-described embodiment, the regulating belt 8, the buttocks belt 10, and the back pad 11 are provided. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that at least one of the regulating belt 8, the buttocks belt 10, and the back pad 11 is eliminated, for example.

[0067] Furthermore, the present disclosure is not limited to the above-described embodiments as long as it conforms to the spirit of the disclosure described in the above-described embodiments. Therefore, the present disclosure may be a configuration in which at least two of the above-described embodiments are combined, or a configuration in which any of the components illustrated or described with reference numerals in the above-described embodiments is eliminated.
