(Embodiment)
Hereinafter, a motion assist device 1 according to this embodiment will be described with reference to FIGS. 1 to 7. FIG.

(1) Overview In this embodiment, the left-right direction and the up-down direction are defined for the motion-assist device 1 as shown in FIG. 1 . For example, in FIG. 1 , the direction in which a first support 11 and a second support 12 (described later) provided in the motion-assist device 1 are aligned is defined as the left-right direction, and the direction in which the first support 11 and the second support 12 extend is defined as the up-down direction. The direction intersecting (perpendicular to) both the left-right direction and the front-back direction is defined as the front-back direction. Although arrows representing these directions (up, down, left, right, front, and back) are shown in FIGS. 1 to 4 and 8 , these arrows are merely for the purpose of assisting the description and do not have any physical substance. Furthermore, the definition of the above directions is not intended to limit the manner in which the motion-assist device 1 of this embodiment is used.

As shown in FIG. 1, the motion-assist device 1 according to this embodiment includes a base 10, at least one support 2 (first support 11 and second support 12 in the illustrated example), and a handrail 13. The support 2 (first support 11 and second support 12) protrudes upward from the base 10. The handrail 13 connects to the support 2 at the top of the support 2. One side of the base 10 is provided with a connecting portion 104 (see FIG. 2) for connecting to another base 10.

With this configuration, one side of the base 10 can be connected to another base 10, so that the base 10 can be placed adjacent to another base 10 to assist a person's movements.

As shown in FIG. 1, the motion-assist device 1 according to this embodiment includes a base 10, at least one support 2 (first support 11 and second support 12 in the illustrated example), and a handrail 13. The support 2 (first support 11 and second support 12) protrudes upward from the base 10. The handrail 13 connects to the support 2 at the top of the support 2. The base 10 is provided with an attachment site for attaching the support 2. The attachment site has a handle 15.

With this configuration, the handle 15 allows the installer to easily lift the installed base 10.

The base 10 according to this embodiment is a base provided in the assist device 1. This allows the base 10 to assist a person's movements when placed adjacent to other bases 10. Furthermore, the installer can easily lift the installed base 10.

1 , the motion-assist device 1 according to this embodiment includes a base 10, at least one support 2 (two in the illustrated example), and a handrail 13. In this embodiment, the motion-assist device 1 includes two support columns 2, namely, a first support column 11 and a second support column 12.

The base 10 is formed in the shape of a rectangular plate, for example, measuring 500 mm x 750 mm. In this embodiment, the longitudinal direction of the base 10 is the left-right direction, and the lateral direction of the base 10 is the front-rear direction. Note that these numerical values are merely examples and are not intended to be limiting. The size of the base 10 may be large enough so that both feet of an adult can fit on the base 10 when walking. For example, the base 10 may be 500 mm x 500 mm. Because both feet rest on the base 10, the user can feel stable when walking.

The base 10 has a plate-shaped first plate 101, a plate-shaped second plate 102, and an edge portion 103 provided on the periphery of the second plate 102.

The second plate 102 is formed in a rectangular plate shape. The second plate 102 has an edge portion 103 on the periphery thereof.

The edge portion 103 is made of rubber. The edge portion 103 is attached to the peripheral edge of the second plate 102 by sandwiching the peripheral edge of the second plate 102.

The first plate 101 is formed in a rectangular plate shape. The first plate 101 is fitted into the edge portion 103 to fill the gap between the second plate 102 and the edge portion 103.

When the base 10 is installed in the installation location, the tip of the edge 103 is in contact with the installation surface (e.g., the floor). When the base 10 is installed, the upper surface of the edge 103 is formed to have a gentle slope.

As shown in FIG. 2, one side of the base 10 has a connecting portion 104 that connects to another base 10. In this embodiment, the base 10 has a number of connecting portions 104 corresponding to the number of support posts 2. That is, in this embodiment, the base 10 has two connecting portions 104. When it is necessary to distinguish between the two connecting portions 104, they will be referred to as a first connecting portion 104a and a second connecting portion 104b.

Each of the connecting portions 104 has a handle portion 15 (see Figure 2). Each of the connecting portions 104 has a recess 105 recessed toward the center of the base 10. The recess 105 is formed by cutting out a rectangular shape in the first plate 101 and the second plate 102. Each of the connecting portions 104 has a raised portion 106 as a handle portion 15 on the edge forming the recess 105. Specifically, the raised portion 106 is provided on the cut-out edge of the second plate 102. In other words, the base 10 has two raised portions 106. Each of the raised portions 106 is provided on the edge forming the bottom of the recess 105, among the edges forming the recess 105. In this embodiment, the edge forming the bottom of the recess 105 is a side along a direction that intersects (is perpendicular to) the direction in which the base 10 and another base 10 are aligned when connecting to another base 10. In other words, the raised portion 106 is provided on the edge of the rectangular cutout in the second plate 102, along a direction that intersects (is perpendicular to) the direction in which the base 10 and another base 10 are lined up when connecting to another base 10.

The rising portion 106 is formed in an L-shape when the action-assist device 1 is viewed from the front to back. That is, the rising portion 106 has a first member 107 extending upward and a second member 108 extending from the upper end of the first member 107 in a direction away from the center of the base.

When the base 10 is installed, the tip of the edge 103 of the base 10 comes into contact with the installation surface. Furthermore, the upper surface of the edge 103 is gently inclined. As a result, the edge 103 does not have a location on which to hook fingers or other objects, making it difficult to lift the base 10. Therefore, by having the rising portion 106 include the first member 107 and the second member 108, the installer installing the motion-assist device 1 can hook their fingers on the rising portion 106, making it easy to lift the installed base 10. Furthermore, the installer can easily carry the base 10.

The first connecting portion 104a and the second connecting portion 104b are provided at both ends of the base 10 along a predetermined direction. In this embodiment, the first connecting portion 104a and the second connecting portion 104b are provided at both ends of the base 10 along the left-right direction (the longitudinal direction of the base 10).

Furthermore, the base 10 has four screw holes 109 in each of the first connecting portion 104a and the second connecting portion 104b, i.e., a total of eight screw holes 109, in order to screw the support 2 (first support 11, second support 12) to the base 10 (see Figure 7). Specifically, each screw hole 109 is provided in the second plate 102 at a location where the connecting portion 104 is located.

In this embodiment, both the first support pillar 11 and the second support pillar 12 are attached to a single base 10. That is, both the first support pillar 11 and the second support pillar 12 protrude upward from the base 10.

The first support pillar 11 extends in the vertical direction. As shown in FIG. 2, the first support pillar 11 includes a first support bracket 113 (support bracket) at its lower end for fixing the first support pillar 11 to the base 10. As shown in FIG. 1, the first support pillar 11 has a first upper support pillar 111 and a first lower support pillar 112. The first upper support pillar 111 and the first lower support pillar 112 are cylindrical. The first upper support pillar 111 is inserted into the upper part of the first lower support pillar 112. The vertical length of the first support pillar 11 can be adjusted by adjusting the amount by which the first upper support pillar 111 is inserted into the first lower support pillar 112 relative to the first lower support pillar 112. The first lower support pillar 112 is provided with a first support bracket 113 at its lower end. The first support bracket 113 is attached to the first connecting portion 104a. Specifically, the first support bracket 113 is fitted into the recess 105 of the first connecting portion 104a. When the first support bracket 113 is fitted into the recess 105 of the first connecting portion 104a, the first support bracket 113 comes into contact with the first member 107 of the rising portion 106. In other words, the first member 107 of the rising portion 106 of the first connecting portion 104a also functions to position the first support bracket 113.

Since the first support bracket 113 is attached to the first connecting portion 104a, the first connecting portion 104a can also be said to be the attachment portion of the first support bracket 113.

As shown in FIG. 2, the first support bracket 113 is formed in the shape of a rectangular plate. The first support bracket 113 has four first screw holes 114 at its four corners. Note that three first screw holes 114 are shown in FIG. 6. The four first screw holes 114 correspond one-to-one to the four screw holes 109 in the first connecting portion 104a of the base 10. Furthermore, the first support bracket 113 has two second screw holes 115. The two second screw holes 115 are arranged along the front-to-rear direction. Note that one second screw hole 115 is shown in FIG. 6. When fixing the first support bracket 113 to the base 10, a screw is inserted into each of the four first screw holes 114 and screwed into the corresponding screw holes 109 of the base 10. When the first support bracket 113 is attached to the first connecting portion 104a, the two second screw holes 115 are located on the opposite side of the first lower support 112 from the rising portion 106 of the first connecting portion 104a.

The second support pillar 12 extends in the vertical direction. As shown in FIG. 2, the second support pillar 12 includes a second support bracket 123 (support bracket) at the lower end of the second support pillar 12 for fixing the second support pillar 12 to the base 10. As shown in FIG. 1, the second support pillar 12 has a second upper support pillar 121 and a second lower support pillar 122. The second upper support pillar 121 and the second lower support pillar 122 are cylindrical. The second upper support pillar 121 is inserted into the upper part of the second lower support pillar 122. The vertical length of the second support pillar 12 can be adjusted by adjusting the amount by which the second upper support pillar 121 is inserted into the second lower support pillar 122 relative to the second lower support pillar 122. The second lower support pillar 122 is provided with a second support bracket 123 at the lower end of the second lower support pillar 122. The second support bracket 123 is attached to the second connecting portion 104b. Specifically, the second support bracket 123 is fitted into the recess 105 of the second connecting portion 104b. When the second support bracket 123 is fitted into the recess 105 of the second connecting portion 104b, the second support bracket 123 comes into contact with the first member 107 of the rising portion 106. In other words, the first member 107 of the rising portion 106 of the second connecting portion 104b also functions to position the second support bracket 123.

Since the second support bracket 123 is attached to the second connecting portion 104b, the second connecting portion 104b can also be said to be the attachment portion of the second support bracket 123.

As shown in FIG. 2, the second support bracket 123 is formed in the shape of a rectangular plate. The second support bracket 123 has four first screw holes 124 at its four corners. Note that three first screw holes 124 are shown in FIG. 6. The four first screw holes 124 correspond one-to-one to the four screw holes 109 in the second connecting portion 104b of the base 10. Furthermore, as shown in FIG. 6, the second support bracket 123 has two second screw holes 125. The two second screw holes 125 are arranged along the front-to-rear direction. When fixing the second support bracket 123 to the base 10, a screw is inserted into each of the four first screw holes 124 and screwed into the corresponding screw holes 109 in the base 10. When the second support bracket 123 is attached to the second connecting portion 104b, the two second screw holes 125 are provided on the opposite side of the second lower support 122 from the rising portion 106 of the second connecting portion 104b.

The handrail 13 connects to the support pillar 2 at the top of the support pillar 2. That is, the handrail 13 connects to the first support pillar 11 and the second support pillar 12 at the top of the first support pillar 11 and the second support pillar 12. More specifically, the handrail 13 connects to the first upper support pillar 111 and the second upper support pillar 121 at the upper ends of the first upper support pillar 111 and the second upper support pillar 121. The handrail 13 has a first handrail 131 and a second handrail 132.

The handrails 13 include a pair of first handrails 13 extending in the same direction (vertical direction) as the support posts 2 (first support post 11 and second support post 12). In this embodiment, the pair of first handrails 131 are arranged in the left-right direction. When it is necessary to distinguish between the pair of first handrails 131, they will be referred to as first handrail 131a and first handrail 131b.

The first handrail 131 is positioned outward relative to the support post 2. That is, the first handrail 131a is positioned outward relative to the first support post 11. The first handrail 131b is positioned outward relative to the second support post 12.

When the base 10 is viewed from above, of the two ends of the first handrail 131 in the direction from the support 2 toward the first handrail 131, the end farthest from the support 2 overlaps with the edge of the base 10. In other words, when the base 10 is viewed from above, of the two ends of the first handrail 131a in the direction from the first support 11 toward the first handrail 131a (left-right direction), the end farthest from the first support 11 overlaps with the edge of the base 10. When the base 10 is viewed from above, of the two ends of the first handrail 131b in the direction from the second support 12 toward the first handrail 131b (left-right direction), the end farthest from the second support 12 overlaps with the edge of the base 10. That is, when the base 10 of the action-assist device 1 is connected to the base 10 of another action-assist device 1 (another base 10), no excessive gap is created between the first handrail 131 of the action-assist device 1 and the first handrail 131 of the other action-assist device 1 (another first handrail 131) that would allow a person (pedestrian) to become pinched between the first handrail 131 and the other first handrail 131. In other words, when the base 10 is connected to the other base 10, the first handrail 131 and the other first handrail 131 come into contact with each other.

Here, "when the base 10 is viewed from above, the end of the first handrail 131 overlaps with the edge of the base 10" means not only that the end of the first handrail 131 actually overlaps with the edge of the base 10, but also that the end of the first handrail 131 overlaps with part of the imaginary line L1 connecting the edges of the base 10 at the recess 105 of the base 10 (see Figure 3).

The second handrail 132 extends in a direction intersecting the first handrail 131. Specifically, the second handrail 132 extends in the left-right direction. The second handrail 132 includes an upper handrail 133 and a lower handrail 134 provided below the upper handrail 133.

The outer shape of the joint between the first handrail 131 and the upper handrail 133 is curved. The curve radius of the joint is large enough to prevent a person from being pinched when the first handrail 131 comes into contact with another first handrail 131. For example, the curve radius of the joint is smaller than the radius of curvature of a person's neck.

Furthermore, the action-assist device 1 includes at least one cover 14. In this embodiment, the action-assist device 1 includes covers 14 in a number corresponding to the number of support columns 2. That is, in this embodiment, the action-assist device 1 includes two covers 14. The two covers 14 correspond one-to-one to the first support columns 11 and the second support columns 12. The covers 14 are temporarily placed on the support columns 2 (first support column 11, second support column 12) before they are attached to the base 10 (see FIG. 2). For example, for the first support column 11, the cover 14 is temporarily placed on the first lower support column 112, and for the second support column 12, the cover 14 is temporarily placed on the second lower support column 122. When the support columns 2 (first support column 11, second support column 12) are fixed (screw-fixed) to the base 10, the covers 14 temporarily attached to the support columns 2 are moved downward until they contact the base 10. As a result, the cover 14 is provided to cover the recessed portion 105 and raised portion 106 of the connecting portion 104. In other words, the cover 14 is provided to cover the recessed portion 105 and raised portion 106 of the connecting portion 104 to which the corresponding support 2 is attached. This prevents a pedestrian using the movement-assist device 1 from tripping over the recessed portion 105 and raised portion 106. Note that the cover 14 is omitted from Figure 6.

The motion-assist device 1 is configured to be connectable to other motion-assist devices 1. That is, the base 10 is configured to be connectable to another base 10. For example, as shown in FIG. 4, the base 10a of the motion-assist device 1a and the base 10b of the motion-assist device 1b are configured to be connectable.

As shown in FIG. 5, the motion-assist device 1 further includes an interconnecting member 16. The interconnecting member 16 connects the first support bracket 113 (or the second support bracket 123) attached to the base 10 of the motion-assist device 1 with the second support bracket 123 (or the first support bracket 113) attached to the base 10 (other base 10) of another motion-assist device 1. Specifically, the interconnecting member 16 is formed in the shape of a rectangular plate, and has four screw holes 161 to 164 at its four corners (see FIG. 7). The screw holes 161 and 162 are arranged side by side in the front-to-rear direction. The screw holes 163 and 164 are arranged side by side in the front-to-rear direction.

When connecting a base 10 to another base 10, for example, of the four screw holes 161-164, screw holes 161 and 162 aligned in the front-to-rear direction correspond to the two second screw holes 125 of a second support bracket 123 attached to the base 10. Screws are inserted into screw hole 161 and one of the two second screw holes 125, and into screw hole 162 and the other of the two second screw holes 125, respectively, and the second support bracket 123 is fixed to the interconnecting member 16 by being screwed in place. Furthermore, of the four screw holes 161-164, screw holes 163 and 164 aligned in the front-to-rear direction correspond to the two second screw holes 115 of a first support bracket 113 attached to the other base 10. Screws are inserted through screw hole 163 and one of the two second screw holes 115, and through screw hole 164 and the other of the two second screw holes 115, and the screws are fastened to secure the first support bracket 113 to the interconnecting member 16.

(3) Effects As described above, the motion-assist device 1 of this embodiment includes the base 10, at least one support 2 (first support 11, second support 12) protruding upward from the base 10, and the handrail 13 connected to the support 2 at an upper portion of the support 2. One side of the base 10 is provided with a connecting portion 104 that connects to another base 10.

With this configuration, one side of the base 10 can be connected to another base 10, so that the base 10 can be placed adjacent to another base 10 to assist a person's movements.

The movement-assist device 1 of this embodiment also includes a base 10, at least one support 2 (first support 11, second support 12) protruding upward from the base 10, and a handrail 13 connected to the support 2 at its upper portion. The base 10 is provided with an attachment portion for attaching the support 2. The attachment portion has a handle portion 15.

The base of a conventional motion-assist device (hereinafter referred to as the comparative motion-assist device) is quite heavy to prevent the comparative motion-assist device from easily shifting from its installed location. This makes it difficult for the installer to lift the installed base when moving it.

In this embodiment, the installer can easily lift the installed base 10 by using the handle portion 15.

(4) Modifications Modifications will be described below. The modifications described below can be applied in appropriate combination with the above embodiment.

(4.1) Modification 1
The second handrail 132 of the handrail 13 described above has a configuration including an upper handrail 133 and a lower handrail 134. However, this configuration is not limited to this. The second handrail 132 may have only an upper handrail.

In other words, the second handrail 132 does not necessarily have to have two handrails extending in the left-right direction in the up-down direction; it may have only one handrail extending in the left-right direction.

(4.2) Modification 2
When the bases 10a and 10b are connected to each other, the support columns 2 are attached to the connecting portions 104 of the bases 10a and 10b, which are connected by the interconnecting members 16 (see FIG. 4). However, the present invention is not limited to this configuration.

When connecting base 10a and base 10b, one support 2 may be attached to the two connecting portions 104 to be connected. For example, when connecting base 10a and base 10b, one support 11a is attached to the second connecting portion 104b of base 10a and the first connecting portion 104a of base 10b to be connected (see Figure 8).

Since support pillar 11a has the same configuration as the first support pillar 11 and second support pillar 12 described above, its description will be omitted here.

The support bracket attached to the lower end of the support post 11a is fitted into the second connecting portion 104b of the connected base 10a and the first connecting portion 104a of the base 10b. At this time, one of the two left-right ends of the support bracket of the support post 11a contacts the first member 107 of the rising portion 106 of the second connecting portion 104b of the base 10a. Furthermore, the other left-right end of the support bracket of the support post 11a contacts the first member 107 of the rising portion 106 of the first connecting portion 104a of the base 10b.

In variant 2, a cover 14a is provided to cover two connecting portions 104, namely the second connecting portion 104b of base 10a and the first connecting portion 104a of base 10b.

In addition, in variant 2, handrails 13a are provided at the top of the supports 2 (the first support 11 of base 10a and the second support 12 of base 10b) provided at both ends in the direction in which base 10a and base 10b are aligned (here, the left-right direction) and connect to the supports 2.

The handrail 13a has a pair of first handrails 135 that extend in the direction in which the support posts 2 extend (vertical direction), and a second handrail 136 that extends in a direction intersecting the first handrails 135. The second handrail 136 is composed of a single handrail that extends in the horizontal direction. When distinguishing between the pair of first handrails 135, they are referred to as the first handrail 135a and the second handrail 135b.

The first handrail 135 is positioned outward from the support posts 2 (the first support post 11 of base 10a and the second support post 12 of base 10b) provided at both ends in the direction in which base 10a and base 10b are aligned. When base 10a is viewed from above, of the two ends of first handrail 135a in the direction from the first support post 11 of base 10a toward first handrail 135a, the end farthest from the first support post 11 of base 10a overlaps with the edge of base 10a. When base 10b is viewed from above, of the two ends of first handrail 135b in the direction from the second support post 12 of base 10b toward first handrail 135b, the end farthest from the second support post 12 of base 10b overlaps with the edge of base 10b.

The upper part of the support 11a, which is attached to the second connecting portion 104b of the base 10a and the first connecting portion 104a of the base 10b, is connected to the connecting portion 137 provided on the handrail 13a.

(4.3) Modification 3
The base 10 of the action-assist device 1 has a configuration including the raised portion 106 as the handle portion 15, but is not limited to this configuration.

As shown in Figure 9, the base 10 of the action-assist device 1 may be provided with a hinge 200 as the handle 15 instead of the raised portion 106.

(4.4) Modification 4
Although the interconnecting member 16 is used to connect the two bases 10, the present invention is not limited to this configuration. To connect the two bases 10, the two bases 10 may be tenoned.

(4.5) Modification 5
The handle 15 is configured to be provided on the edge that forms the bottom of the recess 105. However, the present invention is not limited to this configuration.

The handle portion 15 may be provided on an edge along the direction in which the base 10 and another base 10 are aligned when connecting to another base 10.

(4.6) Modification 6
The handle portion 15 is configured to be provided on both of the two connecting portions 104 of the base 10. However, this configuration is not limited to this. The handle portion 15 may be provided on one of the two connecting portions 104 of the base 10.

The base 10 can be easily lifted even with only one handle 15. Furthermore, the base 10 with two handles 15 is more suitable for carrying than the base with one handle 15, as it can be held with both hands.

(4.7) Modification 7
The first connecting portion 104a and the second connecting portion 104b are configured to be provided at both ends along the longitudinal direction of the base 10. However, the present invention is not limited to this configuration.

The first connecting portion 104a and the second connecting portion 104b may be provided at both ends of the base 10 along the short side.

(4.8) Modification 8
The handle 15 is configured to be applied to the action-assist device 1 on the premise that the first support bracket 113 and the second support bracket 123 each have a second screw hole (second screw hole 115, second screw hole 125). That is, the handle 15 is configured to be provided to the action-assist device 1 on the premise that the support 2 can be connected at both ends in the direction in which the support 2 are arranged. However, the present invention is not limited to this configuration.

The handle 15 may be applied to a motion-assist device in which at least one of the first support bracket 113 and the second support bracket 123 does not have a second screw hole. In other words, the handle 15 may be applied to a motion-assist device that can be connected at only one end of the direction in which the support posts 2 are aligned, or to a motion-assist device that cannot be connected at all.

(summary)
As described above, the motion-assist device (1) of the first aspect includes a base (10), at least one support (2) protruding upward from the base (10), and a handrail (13) connected to the support (2) at an upper portion of the support (2). One side of the base (10) is provided with a connecting portion (104) for connecting to another base (10).

With this configuration, one side of the base (10) can be connected to another base (10), so that the base (10) can be placed adjacent to another base (10) to assist a person's movements.

In the second aspect of the motion-assist device (1), in the first aspect, the support (2) includes support brackets (e.g., first support bracket 113, second support bracket 123) for fixing the support (2) to the base (10). The support brackets are attached to the connecting portion (104).

With this configuration, when the bases (10) are connected, the support brackets are also adjacent, so the support posts (2) attached to one base (10) are adjacent to the support posts (2) attached to another base (10). As a result, handrails can be installed continuously, allowing for continuous assistance to the user's movements.

The motion-assist device (1) of the third aspect is the same as the second aspect, but further includes an interconnecting member (16). The interconnecting member (16) connects a support bracket (e.g., the first support bracket 113 or the second support bracket 123) to another support bracket (e.g., the second support bracket 123 or the first support bracket 113) attached to another base (10).

With this configuration, the interconnecting member (16) can be used to more securely connect the base (10) to other bases (10).

In the fourth aspect of the motion-assist device (1), in any of the first to third aspects, the connecting portion (104) has a handle portion (15).

This configuration allows the base (10) to be easily lifted.

In the fifth aspect of the motion-assist device (1), the fourth aspect has a connecting portion (104) that has a recess (105) recessed toward the center of the base (10). The connecting portion (104) has a raised portion (106) serving as a handle (15) on the edge that forms the recess (105).

This configuration allows the base (10) to be easily lifted.

In the sixth aspect of the motion-assist device (1), in the fifth aspect, the raised portion (106) is provided on the edge that forms the bottom of the recess (105) among the edges that form the recess (105).

With this configuration, the raised portion (106) can function not only as a handle (15) but also as a positioning device when attaching the support (2).

In the seventh aspect of the motion-assist device (1) of any of the first to sixth aspects, the connecting portions (104) are provided at both ends of the base (10) along a predetermined direction (e.g., the left-right direction).

This configuration allows other bases (10) to be connected to both ends of the base (10) in a specified direction.

In the eighth aspect of the motion-assist device (1), in any of the first to seventh aspects, the handrail (13) has a first handrail (131) extending in the direction in which the support (2) extends, and a second handrail (132) extending in a direction intersecting the first handrail (131). The first handrail (131) is positioned outward from the support (2). When the base (10) is viewed from above, the end of the first handrail (131) farthest from the support (2) in the direction from the support (2) toward the first handrail (131) (e.g., left-right direction) overlaps with the edge of the base (10).

With this configuration, when the base (10) is connected to another base (10), the posts (2) can be placed adjacent to each other without any gaps. This reduces the possibility of a person being trapped between two adjacent posts (2).

In the ninth aspect of the motion-assist device (1), in the eighth aspect, the second handrail (132) includes an upper handrail (133) and a lower handrail (134) provided below the upper handrail (133).

With this configuration, the provision of an upper handrail (133) and a lower handrail (134) can assist the user in standing up.

The base (10) of the tenth aspect is a base provided in the motion-assist device (1) of any of the first to ninth aspects.

This configuration allows the base (10) to be placed adjacent to other bases (10) and assist a person's movements.

The movement-assist device (1) of the eleventh aspect comprises a base (10), at least one support (2) protruding upward from the base (10), and a handrail (13) connected to the support (2) at the upper part of the support (2). The base (10) is provided with an attachment portion for attaching the support (2). The attachment portion has a handle portion (15).

With this configuration, the installer can easily lift the installed base (10) by using the handle (15).

In the twelfth aspect of the motion-assist device (1) of the eleventh aspect, the attachment portion has a recess (105) recessed toward the center of the base (10). The attachment portion has a raised portion (106) serving as a handle portion (15) on the edge forming the recess (105).

With this configuration, the raised portion (106) can be used as a handle (15) to easily lift the installed base (10).

In the thirteenth aspect of the motion-assist device (1), in the twelfth aspect, the raised portion (106) is provided on the edge that forms the bottom of the recess (105) among the edges that form the recess (105).

With this configuration, the raised portion (106) can function not only as a handle (15) but also as a positioning device when attaching the support (2).

In the fourteenth aspect of the motion-assist device (1), in any of the eleventh to twelfth aspects, the handles (15) are provided at both ends of the base (10) along a predetermined direction (e.g., the left-right direction).

With this configuration, the two handles (15) allow it to be held with both hands, making it suitable not only for lifting the base (10) but also for carrying it around.
