DETAILED DESCRIPTION OF THE INVENTION
[0012] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than the following embodiments and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure.
[0013] (Embodiment) Hereinafter, the handrail device, base, handrail and support post according to this embodiment will be described with reference to FIGS.
[0014] (1) Overview A handrail device 1 according to this embodiment assists, for example, a user's walking motion. As shown in Fig. 1, the handrail device 1 includes a base 11, a support 12 protruding upward from the base 11, and a handrail 13 supported by the single support 12. The base 11 includes a plate 101 and an edge 102 provided on at least a portion of a peripheral edge 111 of the plate 101. When the base 11 is installed, an upper surface 121 of the edge 102 is gently inclined.
[0015] The gently sloping upper surface 121 of edge portion 102 reduces the possibility that the user will trip over peripheral edge portion 111 of base 11 when walking.
[0016] Furthermore, in the handrail device 1 according to this embodiment, the handrail 13 is configured to be connectable to an assisting device that assists the user's movements. The assisting device will be described later.
[0017] The handrail device 1 is configured to be connectable to an assisting device, and therefore, by connecting it to an existing assisting device, for example, it is possible to smoothly assist the user's successive movements.
[0018] (2) Composition As shown in Fig. 1, the handrail device 1 according to this embodiment includes a base 11, one or more (two in the illustrated example) support posts 12 protruding upward from the base 11, and one or more (two in the illustrated example) handrails 13. Each of the two handrails 13 in Fig. 1 is configured to be connectable to a connecting portion 14. The handrail device 1 is a device that assists a user in walking, and is installed, for example, in a hallway in a house.
[0019] The base 11 has a plate-like plate 101 and an edge portion 102. The base 11 is formed to have a size of, for example, 60 cm x 90 cm. Note that these numerical values are merely examples and are not intended to be limiting. The size of the base may be large enough that both feet of an adult can fit on the base 11 when walking. Since both feet rest on the base 11, the user can feel stable when walking.
[0020] The plate 101 is formed in a rectangular plate shape. The plate 101 has an edge portion 102 provided on at least a part of a peripheral edge portion 111 of the plate 101. In this embodiment, the edge portion 102 is provided around the entire periphery of the peripheral edge portion 111 (see FIG. 1). The plate 101 has a plurality of mounting portions 103 for mounting the support posts 12. The support post 12 is mounted to one selected mounting portion 103 from the plurality of mounting portions 103.
[0021] The edge portion 102 is made of rubber. The edge portion 102 has a first portion 123 and a second portion 124 that sandwich the plate 101 (see FIGS. 2A and 2B). The edge portion 102 further has a third portion 125 that connects the first portion 123 and the second portion 124. The first portion 123 is in contact with a portion of the upper surface 112 of the plate 101. The second portion 124 is in contact with a portion of the lower surface 113 of the plate 101. In this embodiment, the first portion 123 is bonded to the upper surface 112 of the plate 101, and the second portion 124 is bonded to the lower surface 113 of the plate 101. The third portion 125 has a recessed portion 126 along a direction D1 from the lower surface 113 of the plate 101 toward the upper surface 112 of the plate 101 (thickness direction). When the base 11 is not installed, the maximum length L1 of the recess 126 in the thickness direction D1 is longer than the length L2 of the second portion 124 in the thickness direction D1. Note that the edge portion 102 is not limited to being made of rubber and may be made of an elastic material.
[0022] In addition, the edge portion 102 is configured to be detachable from the plate 101. By making the edge portion 102 detachable from the plate 101, for example, if the edge portion 102 changes, becomes dirty, or loses softness and hardens while the handrail device 1 is in use, it can be replaced with a new edge portion 102 to restore the ability to prevent tripping.
[0023] When the base 11 is not installed in the installation location, the tip 127 of the third part 125 is located at a position lower than the lower surface of the second part 124 (see FIG. 2A).
[0024] When the base 11 is installed at the installation location, the tip 127 of the third part 125 is located at the same position as the lower surface of the second part 124 (see FIG. 2B). Here, the concept of "identical" includes not only perfect agreement but also an allowable range of error.
[0025] By deforming the third portion 125 so that the tip portion 127 is located lower than the second portion 124 when the base 11 is not installed at the installation location, and so that the tip portion 127 is located at the same position as the second portion 124 when the base 11 is installed at the installation location, the upper surface 121 of the edge portion 102 can be made to have a gentle slope. Furthermore, by providing a recess 126 in the edge portion 102, the tip portion 127 can be made to fit more easily into the installation location when the base 11 is installed at the installation location. In other words, the radius of curvature of the upper surface 121 of the edge portion 102 can be increased, and therefore the upper surface 121 of the edge portion 102 can be made to have a more gentle slope. In other words, the slope of the upper surface 121 of the edge portion 102 is formed to be gentle when the base 11 is installed.
[0026] Here, "gentle slope" includes cases where the slope angle with respect to the ground is 30 degrees or less. Preferably, "gentle slope" includes cases where the slope angle is 8 degrees to 12 degrees. More preferably, "gentle slope" includes cases where the slope angle is 10 degrees. Here, each numerical value is an example, and it is not intended to be limited to these numerical values. Furthermore, the slope angle does not necessarily have to exactly match the above numerical values, but also includes an allowable error.
[0027] Furthermore, if no recess is provided in the edge portion, the adhesion between the underside of the plate and the second portion may come off when the third portion 125 is deformed when the base is installed in the installation location. Therefore, in this embodiment, by providing recess 126 in edge portion 102, it is possible to reduce the possibility that the adhesion between underside 113 of plate 101 and second portion 124 will come off when the third portion 125 is deformed when the base 11 is installed in the installation location.
[0028] One or more posts 12 are associated with one or more handrails 13 in a one-to-one relationship. Each post 12 connects to its corresponding handrail 13 by itself. That is, the handrail device 1 is configured so that each of the one or more handrails 13 is supported by only one corresponding post 12. Each post 12 has a first post 12a and a second post 12b (see FIG. 1). The second post 12b of the post 12 is connected to the corresponding handrail 13.
[0029] The support 12 is attached to one selected mounting portion 103 from among the multiple mounting portions 103. For example, the first support 12a of the support 12 is fixed to the selected mounting portion 103 with a screw or the like. The support 12 is configured so that its height can be adjusted in the vertical direction (thickness direction D1). The upper end of the support 12, i.e., the upper end of the second support 12b, is connected to the handrail 13.
[0030] Each of the one or more handrails 13 is supported by a corresponding one of the support posts 12. When viewed from direction D2, the handrail 13 is formed in the shape of a curved rod. One end of the curved rod is connected to the support post 12, and the other end is connected to the connecting portion 14. Here, the radius of curvature of the curved rod is, for example, 80 mm (R80). Note that this value is an example and is not intended to be limiting. By increasing the radius of curvature, it becomes easier for the user to grasp the handrail 13 from end to end. In other words, by increasing the radius of curvature, the handrail 13 has a shape that is user-friendly.
[0031] The connecting unit 14 connects one handrail 13 to another handrail 13. The connecting unit 14 assists the user's walking between the two connected handrails 13. For example, the connecting unit 14 connects two handrails 13 provided on the same handrail device 1, or connects one handrail 13 provided on the handrail device 1 to a handrail 13 provided on an assisting device that assists the user's movements. In other words, the handrail device 1 is configured to be able to connect the handrail 13 to another handrail 13 on the same handrail device 1, or to a handrail 13 on an assisting device.
[0032] The handrail device 1 is connected to the handrail 13 of the assist device via the connecting portion 14, allowing the user to smoothly transition between successive movements. In other words, the connecting portion 14 is used as a handrail that assists the user's walking.
[0033] For example, if the assist device is a device that assists the user in standing up and standing down, by connecting the handrail device 1 and the assist device, the user can smoothly transition from a sitting position to a standing up position and then to a walking position. Also, the user can smoothly transition from a walking position to a sitting position.
[0034] Alternatively, if the assist device is a device that assists the user in walking over a step, by connecting the handrail device 1 and the assist device, when moving from a place with a step (for example, a hallway) to a flat place (corridor), the user can smoothly transition from walking up the step to walking on the flat. Also, when moving from a flat place to a place with a step, the user can smoothly transition from walking on the flat to walking down the step.
[0035] (3) Specific examples There are various care products (the handrail device 1, the assist device) to assist users who require care in their daily lives at home. For example, the care product in FIG. 3A shows a walking assist device 1000 as an example of the handrail device 1. The care product in FIG. 3B shows an example of a first assist device 1001. The care product in FIG. 3C shows an example of a second assist device 1002. The care product in FIG. 3D shows an example of a third assist device 1003. The care product in FIG. 3E shows an example of a fourth assist device 1004. Note that when there are multiple walking assist devices 1000 as the handrail device 1 shown in FIG. 3A, the multiple handrail devices 1 may include assist devices in addition to the handrail device 1.
[0036] The walking assist device 1000 shown in FIG. 3A as the handrail device 1 assists a user's walking at the entrance of a house or in a hallway within the house. A first assist device 1001 shown in FIG. 3B assists a user in going up and down an interior entranceway with a step. A second assist device 1002 shown in FIG. 3C, a third assist device 1003 shown in FIG. 3D, and a fourth assist device 1004 shown in FIG. 3E assist a user in getting up and standing in a living room, bedroom, entranceway, or other place within the house. For example, the second assist device 1002 assists a user in standing up from a sitting position in a living room or other place within the house. The third assist device 1003 and the fourth assist device 1004 assist a user in getting up or standing up from a lying position in a bedroom or other place within the house.
[0037] A user may perform multiple actions consecutively in daily life. For example, when a user moves from the entrance to a hallway, the user stands up from a state of taking off their shoes (i.e., sitting), and starts walking. That is, the user performs a standing up action and a walking action consecutively. Therefore, as shown in FIGS. 4 and 5 , by connecting the walking aid device 1000 to the second aid device 1002 or the third aid device 1003, the transition from the standing up action to the walking action can be made smooth. For example, by connecting the walking aid device 1000 to the second aid device 1002 or the third aid device 1003, a user who sits on a step at the entrance and takes off their shoes can stand up using the second aid device 1002 or the third aid device 1003, and then start walking using the walking aid device 1000.
[0038] Furthermore, when moving from the entrance to the hallway, by connecting the walking aid device 1000 to the first aid device 1001, the user can smoothly transition from walking up to the hallway at the inner entrance, which has a large step, to walking.
[0039] 6 to 9, it is also possible to connect a plurality of walking assistance devices 1000. By connecting a plurality of walking assistance devices 1000, it is possible to assist walking over a long distance.
[0040] FIG. 6 shows an example of a combination of walking aid devices 1000 for assisting movement from an entrance to a corridor. By making the length of the support pole 12 of the walking aid device 1000 (walking aid device 1010 in the figure) installed at the entrance shorter than the length of the support pole 12 of the walking aid device 1000 (walking aid device 1011 in the figure) connected to the walking aid device 1010, the walking aid device 1010 can be adapted to steps at the entrance. Also, there are cases where the connecting unit 14 crosses a door 2000 that serves as an entrance to a room. In this case, the connecting unit 14 connects two walking aid devices 1000 (walking aid devices 1011 and 1012 in the figure) so that the walking aid device 1000 can rotate around one of the ends of the connecting unit 14 as a rotation axis.
[0041] FIG. 7 shows an application example in which assistance is provided for moving from a hallway to a room. Moving from the hallway to the room requires a 90-degree turn. Therefore, an L-shaped connector 14 (connector 1400 in the figure) is used at the boundary between the hallway and the room. Furthermore, if there is a step (threshold step) at the boundary between the hallway and the room, the walking aid device 1000 can be installed on a ramp 2010. In this case, the attachment portion between the support 12 and the base 11 of the walking aid device 100 placed on the ramp 2010 is rotatable. This allows the walking aid device 1000 to be installed according to the inclination angle of the ramp 2010. By walking on this ramp 2010, the user can walk smoothly even when there is a threshold step.
[0042] Furthermore, by changing the shape of the connecting handrail corresponding to the connecting portion 14 according to the walking course, it is possible to assist walking along corners. In this case, the user can smoothly change the direction of travel of the user by connecting two walking aid devices 1000 with the connecting portion 14 (L-shaped connecting portion 1400) along the corner (see FIG. 8).
[0043] The walking aid device 1000 can also be used at an outer entrance with a step (see FIG. 9). For example, by connecting two walking aid devices 1000 and making the support pole 12 of one of the two walking aid devices 1000 (walking aid device 1020 in the figure) shorter than the support pole 12 of the other walking aid device 1000 (walking aid device 1021 in the figure), it is possible to accommodate steps at an entrance. This makes it possible to assist the user's walking motion when going up and down steps at an entrance with a step.
[0044] Conventionally, when installing a handrail to assist walking over a long distance, it is necessary to install a pole (support unit) between the floor and the ceiling. In this case, the pole is fixed by abutting one end against the floor and the other end against the ceiling (see JP 2013-92034 A). By installing handrails (horizontal handrail units) between multiple fixed poles, the user's walking motion over long distances is assisted.
[0045] On the other hand, the handrail device 1 of the present application (for example, the walking aid device 1000 shown in FIG. 3A) has a plate-shaped base 11, which makes it possible to stabilize the center of gravity of the handrail device 1. Therefore, there is no need to fix the support poles 12 to the floor and ceiling (see FIGS. 10 to 15). This makes it easy to install the handrail device 1. Also, because there is no need to fix the support poles 12 to the floor and ceiling, the length of the support poles can be shorter than conventional poles. Therefore, when the handrail device 1 is installed, it looks better than before.
[0046] 10 shows an application example of the walking aid device 1000 as a handrail device 1 when assisting movement from a bedroom to another place. By using various connecting parts 14 (such as a straight-line connecting part 1410, a V-shaped connecting part 1411, an L-shaped connecting part 1412, etc.), multiple walking aid devices 1000 can be installed along the user's walking route.
[0047] 11 shows an example of application of the walking assist device 1000 to assist movement in a hallway. In this case, a support post 12 is provided near a wall. A user walks on a base 11 by holding onto a handrail 13 provided on the support post or a connector 14 connected to the handrail 13. The size of the base 11 is such that both feet of an adult can fit on the base 11 when walking, allowing the user to walk on the base 11 in a stable manner.
[0048] 12 and 13 show an application example in which multiple walking aid devices 1000 are combined to assist movement down a corridor. The attachment locations of the support posts 12 on the base 11 can be changed according to the user's walking route. In addition, the shape of the connecting handrails, which correspond to the connecting portions 14 provided on the remaining walking aid devices 1000 other than the walking aid devices 1000 at both ends, can be changed according to the user's walking route.
[0049] 14 shows an application example of the walking aid device 1000 when assisting movement within a room. In this case, multiple walking aid devices 1000 are connected via the connecting unit 14. At this time, the connecting unit 14 (connecting unit 1430 in the figure) may cross in front of a closet 2020. In this case, the connecting unit 1430 connects two walking aid devices 1000 so that they can rotate around one of the ends of the connecting unit 1430 as a rotation axis.
[0050] 15 shows an application example of the walking assist device 1000 when standing up from a bed 2030 and walking. In this case, by placing the handrail 13 beside the bed 2030, the user can step down from the bed 2030 and then walk continuously.
[0051] Furthermore, in conventional handrail devices, the slope of the top surface of the edge is not smooth. For example, the slope of the conventional edge is about 35 degrees. With this slope, the user feels their toes hitting the conventional edge.
[0052] On the other hand, in this embodiment, when the base 11 is installed, the upper surface 121 (see FIGS. 2A and 2B) of the edge portion 102 is gently inclined. Therefore, compared to conventional devices, the user does not feel that their toes are hitting the edge portion 102. This allows the user to walk on the edge portion 102 with a shuffling step. As a result, the possibility of tripping on the edge portion 102 can be reduced.
[0053] (4) Variations Modifications will be described below. The modifications described below can be applied in appropriate combination with the above embodiment.
[0054] (4.1) Variation 1 In the embodiment, each of the two handrails 13 is configured to be connectable to the connecting portion 14, but the present invention is not limited to this configuration.
[0055] One of the two handrails 13 and the connecting portion 14 may be formed integrally.
[0056] As shown in Figures 16 and 17, the handrail device 1A of variant 1 comprises a base 11, one or more (two in the illustrated example) posts 12 protruding upward from the base 11, a handrail 13 (referred to as a first handrail 13 in the variant), and a second handrail 13a. The second handrail 13a includes a first handrail portion 15a and a second handrail portion 14a. The first handrail portion 15a corresponds to the handrail 13. The second handrail portion 14a corresponds to the connecting portion 14. In other words, the second handrail 13a is a component in which the handrail 13 and the connecting portion 14 are integrally formed.
[0057] The first handrail portion 15a and the second handrail portion 14a are connected to each other, that is, the first handrail portion 15a extends from one of both ends of the second handrail portion 14a.
[0058] The handrail device 1A is configured to be disassembled into a base 11, a first part 16a including the support post 12 and the first handrail 13, and a second part 17a including the support post 12 and the second handrail 13a. In other words, the handrail device 1A can be assembled from the base 11, the first part 16a, and the second part 17a. In the following description, the first part 16a will be simply referred to as the support post 16a. Furthermore, the second part 17a will be referred to as the handrail-function-equipped support post 17a. The support post 16a and the handrail-function-equipped support post 17a are included in the concept of a support post in this disclosure.
[0059] When assembling the handrail device 1A, the end (end 131a) of the second handrail portion 14a included in the handrail function-equipped support 17a, to which the first handrail portion 15a does not extend, is connected to the end 131 of the first handrail 13 included in the support 16a. Then, each of the two supports 12 is attached to a corresponding one of the multiple attachment portions 103.
[0060] The following describes the connection between the second handrail 14a and the first handrail 13. The end 131 of the first handrail 13 has a through-hole 132 (see FIG. 18). Furthermore, the tip of the end 131 of the first handrail 13 is formed in an R-shape 133 (see FIG. 18).
[0061] The end 131a of the second handrail 13a has a through-hole 132a (see FIG. 18). Furthermore, the end 131a of the second handrail 13a has a groove 133a along the R-shape 133 (see FIG. 18). When connecting the second handrail 14a and the first handrail 13, the R-shape 133 of the first handrail is fitted into the groove 133a of the second handrail 13a so that the through-hole 132a and the through-hole 132 overlap. Then, the first handrail 13 (post 16a) is connected to the second handrail 13a (handrail-function-equipped post 17a) with a bolt and a nut. Specifically, a bolt is inserted into the through-hole 132 and the through-hole 132a, and the post 16a and the handrail-function-equipped post 17a are connected with the bolt and the nut. This allows the post 16a to rotate around the bolt as the center of rotation. In other words, the part fixed by the bolt and nut can also be called a hinge part.
[0062] As explained above, the handrail device 1A is configured to be assembled from a plurality of parts. The handrail device 1A is configured from the base 11, the support post 16a, and the handrail function-equipped support post 17a. The handrail device 1A is assembled from the base 11, the support post 16a, and the handrail function-equipped support post 17a.
[0063] (4.2) Variation 2 In the first modification, in assembling the handrail device 1A, a connecting support 18, which is a part for connecting to another handrail device, may be used instead of the support 16a.
[0064] As shown in FIG. 19, the connecting support 18 has a support 181 and a connecting portion 182.
[0065] The connecting portion 182 is provided at one end (tip) of the support column 181. The other end of the support column 181 is attached to the base 11 (see FIG. 21).
[0066] 20, the connecting portion 182 has a first connecting portion 183 and a second connecting portion 184. The first connecting portion 183 has a first circular plate portion 183a and a second circular plate portion 183b that face each other in the direction along the support 181. Furthermore, the first connecting portion 183 has a cylindrical shaft portion 183c that connects the first circular plate portion 183a and the second circular plate portion 183b. The diameter of the shaft portion 183c is smaller than both the diameter of the first circular plate portion 183a and the diameter of the second circular plate portion 183b.
[0067] The second connecting portion 184 has a first connecting member 184a and a second connecting member 184b configured to be connectable to the first connecting member 184a. When the first connecting member 184a and the second connecting member 184b are connected, the tip of the second connecting portion 184 forms an annular shape that opens along the axial direction of the shaft 183c. The inner diameter of the annular shape is approximately the same as the diameter of the shaft portion 183c.
[0068] When connecting second connecting portion 184 to first connecting portion 183, first connecting member 184a and second connecting member 184b are connected so as to sandwich shaft portion 183c. This makes second connecting portion 184 rotatable around shaft portion 183c as the center of rotation. In other words, shaft portion 183c and first connecting member 184a and second connecting member 184b can also be said to be hinge portions.
[0069] When connecting the first connecting part 183 to another handrail device, for example, the tip 183d of the first connecting part 183 and the end 131a of the handrail function-equipped support 17a are joined with a bolt and a nut (see FIG. 21). When connecting the second connecting part 184 to another handrail device, for example, the tip 184c of the second connecting part 184 and the tip of the handrail 200 connected to the support 16a are joined with a bolt and a nut (see FIG. 21).
[0070] By using the connecting support 18, the handrail device 1A can be connected to other handrail devices. Note that the connection with the first connecting portion 183 is not limited to the handrail-functioning support 17a. The first connecting portion 183 may be any component that can be connected to the tip end 183d of the first connecting portion 183 with a bolt and nut and is used for a handrail, etc. Furthermore, the connection with the second connecting portion 184 is not limited to the handrail 200 connected to the support 16a. The second connecting portion 184 may be any component that can be connected to the tip end 184c of the second connecting portion 184 with a bolt and nut and is used for a handrail, etc.
[0071] As shown in FIG. 21, when a connecting post 18 is used instead of the support post 16a in the handrail device 1A, the support post 16a can be used as the end portion when connected. In other words, by providing the connecting post 18 between the support post 16a and the handrail function-equipped support post 17a, the handrail can be extended. Note that the number of connecting posts 18 provided between the support post 16a and the handrail function-equipped support post 17a is not limited to one. Multiple connecting posts 18 may be provided between the support post 16a and the handrail function-equipped support post 17a. Alternatively, the connecting post 18 may be used when connecting multiple walking aid devices.
[0072] In addition, the second connecting portion 184 may be configured such that one end of the first connecting member 184a and one end of the second connecting member 184b are joined together in advance by a hinge.
[0073] As described above, the connecting support pillar 18 of Modification 2 has a support pillar 181 and a connecting portion 182 provided at one end (tip) of the support pillar 181. The connecting portion 182 has a first connecting portion 183 and a second connecting portion 184. The second connecting portion 184 is connected to the first connecting portion 183 so as to be rotatable relative to the first connecting portion 183, with the direction along the support pillar 181 as the rotation axis.
[0074] More specifically, first connecting portion 183 has first and second circular disk portions 183a and 183b that face each other in the direction along support pillar 181, and a cylindrical shaft portion 183c that connects first and second circular disk portions 183a and 183b. Second connecting portion 184 is connected to shaft portion 183c so as to be rotatable relative to first connecting portion 183, with the direction along support pillar 181 as the axis of rotation.
[0075] (4.3) Variation 3 Here, modified examples of the connecting support pole 18 will be described with reference to FIGS.
[0076] As shown in FIG. 22, the connecting pillar 19 of the third modification includes a pillar 191 and a connecting portion 192. As shown in FIG.
[0077] The connecting portion 192 is provided at one end (tip) of the support column 191. The other end of the support column 191 is attached to the base 11 (see FIG. 24).
[0078] As shown in FIG. 23, the connecting portion 192 has a first connecting portion 193 and a second connecting portion 194.
[0079] As shown in Fig. 23, the first connecting portion 193 has a shaft portion 193a, a restricting portion 193b, and a flange portion 193c. The shaft portion 193a is cylindrical and is provided at the tip of the support column 191. The restricting portion 193b is connected to the shaft portion 193a on the opposite side of the support column 191 with respect to the shaft portion 193a in the direction along the support column 191 (first direction). The restricting portion 193b has an R-shape with a diameter in a direction perpendicular to the first direction. The diameter of the R-shape is longer than the diameter of the shaft portion 193a. The flange portion 193c is provided along the circumference of the shaft portion 193a on the opposite side of the restricting portion 193b with respect to the shaft portion 193a in the first direction.
[0080] As shown in FIG. 23, the second connecting portion 194 has a first part 194a, a second part 194b, and a third part 194c.
[0081] The first part 194a has a cylindrical shape extending in a direction (second direction) perpendicular to the first direction. The second part 194b is provided along the first direction from an end 194d, which is one of both ends of the first part 194a in the second direction. The end 194d faces the restricting part 193b when the first connecting part 193 and the second connecting part 194 are connected. The surface of the end 194d facing the restricting part 193b has a groove 194e that follows the R-shape 133.
[0082] The second part 194b is cylindrical and extends from the end 194d in the first direction. The third part 194c is located on the second part 194b on the opposite side of the first part 194a in the second direction. The third part 194c has a circular through-hole whose diameter is approximately the same as the diameter of the shaft part 193a.
[0083] When connecting second connecting portion 194 to first connecting portion 193, shaft portion 193a is inserted into the through-hole of third component 194c. This allows second connecting portion 194 to rotate around shaft portion 193a as the center of rotation. In other words, shaft portion 193a and third component 194c can also be considered a hinge portion. Note that third component 194c may be configured to be separable into two in the second direction. If third component 194c is configured to be separable into two, the two separated components are joined together so as to sandwich shaft portion 193a.
[0084] When connecting the first connecting part 193 to another handrail device, for example, the restricting part 193b of the first connecting part 193 and the end part 131a of the handrail function-equipped support 17a are connected with a bolt and a nut (see FIG. 24). When connecting the second connecting part 194 to another handrail device, for example, the second connecting part 194 and the tip of the handrail 200 connected to the support 16a are connected with a bolt and a nut (see FIG. 24).
[0085] By using the connecting support 19, the handrail device 1A can be connected to other handrail devices. Note that the connection with the first connecting portion 193 is not limited to the handrail-functioning support 17a. The first connecting portion 193 may be any component that can be connected to the first connecting portion 193 with a bolt and nut and is used for a handrail, etc. Furthermore, the connection with the second connecting portion 194 is not limited to the handrail 200 connected to the support 16a. The second connecting portion 194 may be any component that can be connected to the second connecting portion 194 with a bolt and nut and is used for a handrail, etc.
[0086] As shown in FIG. 24, when a connecting support 19 is used instead of the support 16a in the handrail device 1A, the support 16a can be used as the end portion when connected. In other words, by providing the connecting support 19 between the support 16a and the handrail function-equipped support 17a, the handrail can be extended. Note that the number of connecting support 19 provided between the support 16a and the handrail function-equipped support 17a is not limited to one. Multiple connecting support 19 may be provided between the support 16a and the handrail function-equipped support 17a. Alternatively, the connecting support 18 may be used when connecting multiple walking aid devices.
[0087] Furthermore, when the third component 194c is configured to be separable into two in the second direction, one end of each of the two separated components may be joined in advance by a hinge.
[0088] As described above, the connecting support 19 of Modification 3 has a support 191 and a connecting portion 192 provided at one end (tip) of the support 191. The connecting portion 192 has a first connecting portion 193 and a second connecting portion 194. The second connecting portion 194 is connected to the first connecting portion 193 so as to be rotatable relative to the first connecting portion 193, with the direction along the support 181 (first direction) as the rotation axis.
[0089] More specifically, first connecting portion 193 has a shaft portion 193a, a restricting portion 193b, and a flange portion 193c. Shaft portion 193a is provided at the tip of support pillar 191. Restricting portion 193b is connected to shaft portion 193a on the opposite side of shaft portion 193a from support pillar 191 in the first direction. Flange portion 193c is provided along the circumference of shaft portion 193a on the opposite side of shaft portion 193a from restricting portion 193b in the first direction. Second connecting portion 194 is connected to shaft portion 193a so as to be rotatable relative to first connecting portion 193.
[0090] The support 191 and the shaft 193a may be integral with each other.
[0091] (4.4) Variation 4 A handrail device 1B according to Modification 4 will be described using Figures 25 to 26. The following describes the handrail device 1B according to Modification 4, focusing on the differences from the above embodiment. Note that the same components as those in the above embodiment are given the same reference numerals, and descriptions thereof will be omitted where appropriate.
[0092] A handrail device 1B of the fourth modification includes a base 11, one support post 12, and one handrail 13, as shown in FIG.
[0093] The support post 12 is fixed with a screw or the like to one of a plurality of mounting portions 103 on a plate 101 of the base 11 (hereinafter referred to as "base plate 101"), the mounting portion 103 being located in the center of the base plate 101. The support post 12 supports a handrail 13. In other words, the support post 12 is connected to the handrail 13.
[0094] The handrail device 1B further includes a plate 201. The plate 201 is generally quadrangular, more specifically generally rectangular, and is made of, for example, polypropylene resin, with a thickness of, for example, 0.75 mm. The plate 201 is attached to the end 131 of the handrail 13. The plate 201 has a protruding portion 201a that protrudes from one of the two long sides. The protruding portion 201a has a through-hole 201b (see FIG. 26). The plate 201 may also be made of other resins, metals, etc. The thickness of the plate 201 is an example and is not limited to this value.
[0095] As shown in Fig. 26, the plate 201 is attached to the end 131 of the handrail 13 using a cap 202, a washer 203, a screw 204, a screw cap 205, and a nut 206. More specifically, the plate 201 is positioned so that the through-hole 132 of the handrail 13 and the through-hole 201b of the plate 201 are aligned, and then the cap 202 is fitted onto the end 131 of the handrail 13 so that the through-hole 202a of the cap 202 is aligned with the through-hole 132 and the through-hole 201b. The handrail 13, the plate 201, and the cap 202 are then joined together using the washer 203, the screw 204, and the nut 206. After joining, the screw cap 205 is attached to the through-hole 202a of the cap 202 to close the through-hole 202a.
[0096] With this configuration, the handrail 13 can function as a handrail by itself, without connecting it to another handrail or a connecting support (for example, connecting support 18). Furthermore, by providing plate 201 at end 131 of handrail 13, it is possible to prevent end 131 of handrail 13 from getting caught in the sleeve of a pedestrian. As a result, it is possible to prevent the pedestrian from falling over due to end 131 of handrail 13 getting caught in the sleeve.
[0097] (4.5) Variation 5 In Modification 4, the plate 201 is provided on the handrail 13, but the present invention is not limited to this configuration. The plate 201 may also be provided on the connecting support 18 shown in Modification 2. Below, the handrail device 1C according to Modification 5 will be described, focusing on the differences from the above embodiment and Modifications 2 to 4. Note that the same components as those in the above embodiment and Modifications 2 and 4 will be assigned the same reference numerals and descriptions thereof will be omitted where appropriate.
[0098] As shown in FIG. 27, a handrail device 1C of the fifth modification includes a base 11 and one connecting support pole 18.
[0099] Similar to the second modification, the connecting support 18 has a support 181 and a connecting portion 182 (see FIG. 27). In the fifth modification, the connecting portion 182 functions as a handrail. That is, the connecting portion 182 corresponds to the handrail of the present disclosure. The connecting support 18 is fixed with a screw or the like to one of a plurality of mounting portions 103 of the plate 101 of the base 11 (hereinafter referred to as the "base plate 101"), which is located in the center of the base plate 101.
[0100] The connecting portion 182 is provided at one end (tip) of the support column 181. The other end of the support column 181 is attached to the base 11. That is, the other end of the support column 181 is fixed to one of the multiple attachment portions 103 that is located in the center of the base plate 101 with a screw or the like.
[0101] The connecting portion 182 is T-shaped, and has a first connecting portion 183 and a second connecting portion 184, similar to the second modification (see FIG. 27).
[0102] The handrail device 1C further includes two plates 201. Each plate 201 is generally quadrangular, more specifically, generally rectangular, and is made of, for example, polypropylene resin, with a thickness of, for example, 0.75 mm. As in the fourth modification, each plate 201 has a protruding portion 201a protruding from one of its two long sides. The protruding portion 201a has a through-hole 201b (see FIG. 26). The plate 201 may also be made of other resins, metals, etc. The thickness of the plate 201 is an example and is not limited to this value.
[0103] One of the two plates 201 is provided at the tip of the first connecting part 183. As in the fourth modification, the one plate 201 is attached to the first connecting part 183 using a cap 202, a washer 203, a screw 204, a screw cap 205, and a nut 206 shown in FIG.
[0104] The other of the two plates 201 is provided at the tip of the second connecting part 184. As in the fourth modification, the other plate 201 is attached to the second connecting part 184 using a cap 202, a washer 203, a screw 204, a screw cap 205, and a nut 206 shown in FIG.
[0105] The method of attaching each plate 201 is the same as in the fourth modification, so a description thereof will be omitted here.
[0106] With this configuration, connecting support pole 18 does not need to be connected to another handrail, etc., and handrail device 1C can function as a handrail by itself. Furthermore, by providing plates 201 on each of first connecting portion 183 and second connecting portion 184 of connecting support pole 18, it is possible to prevent first connecting portion 183 and second connecting portion 184 from getting caught in the sleeve of a pedestrian. As a result, it is possible to prevent the pedestrian from falling over due to first connecting portion 183 and second connecting portion 184 getting caught in the sleeve.
[0107] Furthermore, in Modification 5, the connecting support 19 (see FIGS. 23 and 24) described in Modification 3 may be applied instead of the connecting support 18. In this case, one of the two plates 201 is provided on the restricting portion 193b (see FIG. 24) of the first connecting portion 193 of the connecting support 19. The other of the two plates 201 is provided on the first part 194a of the second connecting portion 194. Even when the connecting support 19 (see FIGS. 23 and 24) is applied, it is possible to prevent a pedestrian from falling over due to the first connecting portion 193 and the second connecting portion 194 getting caught in the sleeve.
[0108] (4.6) Variation 6 The second handrail 13a (hereinafter referred to as "handrail 13a") of the first modification and the connecting support 18 shown in the second modification may be combined.
[0109] The following describes a handrail device 1D according to Modification 6, focusing on the differences from the above-described embodiment and Modifications 1, 2, 4, and 5. Note that the same components as those in the above-described embodiment and Modifications 1, 2, 4, and 5 are given the same reference numerals, and descriptions thereof will be omitted as appropriate.
[0110] As shown in Fig. 28, the handrail device 1D of the sixth modification includes a base 11, a support post 12, a handrail 13a, and a connecting support post 18. Similar to the first modification, the handrail 13a includes a first handrail portion 15a and a second handrail portion 14a (see Fig. 17).
[0111] An end 131a (see FIG. 17) of the second handrail portion 14a is connected to a second connecting portion 184 of the connecting support pole 18. The connection between the end 131a of the second handrail portion 14a and the second connecting portion 184 is achieved in the same manner as the connection between the handrail function-equipped support pole 17a (see FIG. 21) including the second handrail portion 14a and the connecting support pole 18 (see FIG. 21) described in Modification Example 2. Therefore, the method for connecting the end 131a of the second handrail portion 14a and the second connecting portion 184 will not be described here.
[0112] The handrail device 1D further includes a plate 201. The plate 201 is generally quadrangular, more specifically, generally rectangular, and is made of, for example, polypropylene resin, with a thickness of, for example, 0.75 mm. The plate 201 is provided to the first connecting portion 183 of the connecting support 18. As in Modification 4, the plate 201 is attached to the second connecting portion 194 using a cap 202, a washer 203, a screw 204, a screw cap 205, and a nut 206 shown in FIG. 26. Note that the method of attaching each plate 201 is the same as in Modification 4, and therefore a description thereof will be omitted here. Note that the plate 201 may be made of other resins, metals, etc. The thickness of the plate 201 is merely an example and is not limited to this value.
[0113] This configuration allows the handrail device 1D to function as a handrail. Furthermore, by providing the plate 201 to the first connecting portion 183 of the connecting support 18, it is possible to prevent the first connecting portion 183 from getting caught in the sleeve of a pedestrian. As a result, it is possible to prevent the pedestrian from falling over due to the first connecting portion 183 getting caught in the sleeve.
[0114] Furthermore, in Modification 6, the end 131a (see FIG. 17) of the second handrail portion 14a is configured to connect to the second connecting portion 184 of the connecting support pole 18, but this configuration is not limited to this. The end 131a (see FIG. 17) of the second handrail portion 14a may also be connected to the first connecting portion 183 of the connecting support pole 18. In this case, the plate 201 is provided on the second connecting portion 184. This configuration can prevent a pedestrian from falling over due to the second connecting portion 184 getting caught in the sleeve.
[0115] Furthermore, in Modification 6, the connecting support 19 (see FIGS. 23 and 24) described in Modification 3 may be applied instead of the connecting support 18. In this case, the end 131a (see FIG. 17) of the second handrail region 14a is connected to the first connecting portion 193 of the connecting support 19, and the plate 201 is provided on the first part 194a (see FIG. 23) of the second connecting portion 194 of the connecting support 19. Alternatively, the end 131a (see FIG. 17) of the second handrail region 14a may be connected to the first part 194a (see FIG. 23) of the second connecting portion 194 (see FIGS. 23 and 24) of the connecting support 19, and the plate 201 may be provided on the first connecting portion 193. Even when the connecting support 19 (see FIGS. 23 and 24) is applied, it is possible to prevent a pedestrian from falling over due to the first connecting portion 193 or the second connecting portion 194 getting caught in the sleeve.
[0116] (4.7) Variation 7 The second auxiliary device 1002 described in the first embodiment (hereinafter referred to as the auxiliary device 300 in the seventh modification) may be configured to be connected to the handrail device 1E.
[0117] The handrail device 1E includes the support post 16a described in Variation 3. The handrail device 1E is connected to the auxiliary device 300 of Variation 7 via the handrail 200 shown in Variations 2 and 3 and the second connecting portion 184 shown in Variation 2 (hereinafter, in Variation 7, simply referred to as the "connecting portion 184"). A first end of the handrail 200 in the longitudinal direction is connected to the support post 16a of the handrail device 1E. A second end of the handrail 200 in the longitudinal direction is connected to the connecting portion 184 (see Figure 30). The connecting portion 184 is connected to the auxiliary device 300 (see Figure 30).
[0118] The method of connecting the connecting portion 184 and the handrail 200 has been explained in Modification 2, so the explanation will be omitted here.
[0119] As described in Modification 2, the connecting portion 184 has a first connecting member 184a and a second connecting member 184b configured to be connectable to the first connecting member 184a (see FIG. 30). When the first connecting member 184a and the second connecting member 184b are connected, the tip of the second connecting portion 184 becomes annular in shape with an opening along a direction perpendicular to the connecting direction of the first connecting member 184a and the second connecting member 184b.
[0120] 29 to 32, the assist device 300 includes a base 11, one or more (two in the illustrated example) first support posts 312 protruding upward from the base 11, one or more (two in the illustrated example) second support posts 313, and a handrail 310. Each of the two second support posts 313 in FIG. 29 is configured to be connectable to the handrail 310.
[0121] In the auxiliary device 300, when viewed from the direction in which the two second supports 313 are aligned, the two second supports 313 and the two first supports 312 are provided along a direction intersecting (orthogonal to) the base 11. In other words, when viewed from the direction in which the two second supports 313 are aligned, the two second supports 313 and the two first supports 312 do not have any parts that protrude from a plane that includes the two second supports 313 and the two first supports 312.
[0122] The handrail 310 has one or more (two in the illustrated example) connecting portions 311a, 311b. A first circular plate portion 321 and a second circular plate portion 322 facing each other are provided at both ends of the connecting portion 311a. Furthermore, a cylindrical shaft portion that connects the first circular plate portion 321 and the second circular plate portion 322 is provided at both ends of the connecting portion 311a. The first circular plate portion 321 corresponds to the first circular plate portion 183a shown in Modification 2, and the second circular plate portion 322 corresponds to the second circular plate portion 183b shown in Modification 2. Furthermore, the shaft portion that connects the first circular plate portion 321 and the second circular plate portion 322 corresponds to the shaft portion 183c shown in Modification 2.
[0123] The handrail 310 has one or more handrail portions 311c (two in the illustrated example), which correspond to the handrail 13 described in the embodiment. The two handrail portions 311c correspond one-to-one to the two second support posts 313. The two handrail portions 311c are supported by the corresponding second support posts 313. The handrail portion 311c is formed in a curved rod shape when viewed from a direction perpendicular to a plane including the two second support posts 313. One end of the curved rod is connected to the second support post 313, and the other end is connected to the connecting portion 311a. Here, the radius of curvature of the curved rod is, for example, 80 mm (R80). Note that this value is an example and is not intended to be limiting. By increasing the radius of curvature, the user can easily grasp the handrail portion 311c from end to end. In other words, by increasing the radius of curvature, the handrail portion 311c has a user-friendly shape.
[0124] When the auxiliary device 300 is not connected to the handrail device 1E, a separable annular part 320 is attached to the shaft connecting the first circular plate portion 321 and the second circular plate portion 322 (see Figures 29, 30, etc.).
[0125] When connecting the auxiliary device 300 to the handrail device 1E, the connecting part 184 is connected to the shaft part that connects the first circular plate part 321 and the second circular plate part 322. The connecting method is the same as the method for connecting the second connecting part 184 to the first connecting part 183, so a description thereof will be omitted here.
[0126] By connecting the connecting portion 184 to the shaft portion that connects the first circular plate portion 321 and the second circular plate portion 322, the shaft portion can be rotated around the center of the rotation axis. In other words, the shaft portion that connects the first circular plate portion 321 and the second circular plate portion 322 and the first connecting member 184a and the second connecting member 184b can also be said to be a hinge portion.
[0127] Furthermore, the auxiliary device 300 is provided with an openable and detachable face handrail portion 301 that can be attached to and detached from the two second support poles 313.
[0128] As shown in FIGS. 29 and 30 , the face handrail portion 301 has a flat plate 330 and a stop plate portion 331. A main surface 330a of the flat plate 330 is substantially rectangular. The stop plate portion 331 is provided along the main surface 330a of the flat plate 330 so as to protrude from the main surface 330a of the flat plate 330. The stop plate portion 331 includes a main surface 331a. When the flat plate 330 is in an open state, a normal to the main surface 331a of the stop plate portion 331 intersects with a plane including the two second support posts 313 and the two first support posts 312. When the flat plate 330 is in a closed state, a plane including the main surface 331a of the stop plate portion 331 intersects with a plane including the two second support posts 313 and the two first support posts 312. The stop plate portion 331 has a pair of protrusions 331b on a main surface 331a thereof, which protrude in a direction away from the flat plate 330 from both ends along the longitudinal direction of the flat plate 330.
[0129] Furthermore, one or more (two in the illustrated example) rotation stop fittings 332 are provided on a main surface 331a of the stopping plate portion 331. Each rotation stop fitting 332 is substantially U-shaped. That is, each rotation stop fitting 332 has two member pieces 332a, 332b that face each other along the alignment direction of the two second support posts 313 (see FIG. 31). The width between the tips of the two member pieces 332a, 332b of the rotation stop fitting 332 is wider than the diameter of a second locking portion 342 (see FIGS. 31, 32, etc.) described later. The width between the two member pieces 332a, 332b gradually narrows from the tip of each member piece 332a, 332b to a predetermined position toward the main surface 331a of the retaining plate portion 331, and the width between the two member pieces 332a, 332b gradually widens from the predetermined position toward the main surface 331a of the retaining plate portion 331. Here, the width between the member pieces 332a, 332b at the predetermined position of each member piece 332a, 332b is narrower than the diameter of the second locking portion 342.
[0130] Furthermore, as shown in Figures 31 and 32, the surface handrail portion 301 has a rotating shaft portion 340, one or more (two in the illustrated example) first locking portions 341, one or more (two in the illustrated example) second locking portions 342, and two fixing portions 343.
[0131] The two fixing portions 343 are provided at both ends of the rotating shaft portion 340 in the axial direction, and correspond one-to-one to the two second support posts 313. When the surface handrail portion 301 is attached (mounted) to the two second support posts 313, each of the two fixing portions 343 abuts against the corresponding second support post 313. Furthermore, each fixing portion 343 has one or more protrusions that protrude in the axial direction, and when abutting against the corresponding second support post 313, the one or more protrusions are fitted into one or more holes provided in the second support post 313.
[0132] The rotating shaft 340 has a turnbuckle mechanism. When attaching (mounting) the face handrail section 301 to the two second supports 313, the turnbuckle mechanism is operated so that each fixing section 343 presses against the corresponding second support 313. When detaching the face handrail section 301 from the two second supports 313, the turnbuckle mechanism is operated so that each fixing section 343 is released from pressing against the corresponding second support 313.
[0133] Since the rotating shaft 340 has a turnbuckle mechanism, the height of the face handrail part 301, i.e., the height of the flat plate 330, can be adjusted independently of the adjustment of the height of the second support pole 313. In other words, the height of the second support pole 313 and the height of the face handrail part 301 can be adjusted separately.
[0134] Furthermore, a pair of protrusions 331b of the stop plate portion 331 is fitted into the rotating shaft portion 340. This allows the flat plate 330 to rotate around the rotating shaft portion 340 as a rotation axis. Furthermore, because the pair of protrusions 331b of the stop plate portion 331 is fitted into the rotating shaft portion 340, the flat plate 330 is not included in a plane that includes the two second support columns 313 and the two first support columns 312. In other words, when viewed from the direction in which the two second support columns 313 are arranged, the two second support columns 313 and the two first support columns 312 are arranged side by side with the flat plate 330. In other words, when viewed from the direction in which the two second support columns 313 are arranged, the flat plate 330 is arranged forward of the two second support columns 313 and the two first support columns 312. Here, the term "forward" refers to the side opposite the wall with respect to the two second support columns 313 and the two first support columns 312 when the auxiliary device 300 is placed against the wall.
[0135] Each first locking portion 341 has a flat plate shape and is provided on the rotating shaft portion 340 so as to protrude downward from the rotating shaft portion 340, i.e., in a direction toward the base 11 (see FIGS. 31 and 32). Each first locking portion 341 is provided so that the rotation of the flat plate 330 stops at a predetermined position when the (flat plate 330 of) the face handrail portion 301 changes from a closed state (see FIG. 32) to an open state (see FIG. 31). Specifically, when the (flat plate 330 of) the face handrail portion 301 changes from a closed state (see FIG. 32) to an open state (see FIG. 31), each first locking portion 341 abuts against the main surface 331a of the stop plate portion 331. When each first locking portion 341 abuts against the main surface 331a of the stop plate portion 331, the rotation of the flat plate 330 stops, and the state (open state) of the flat plate 330 is fixed.
[0136] The one or more second locking portions 342 are cylindrical and correspond one-to-one to the one or more rotation stop fittings 332. Each second locking portion 342 is provided on the rotating shaft portion 340 on the opposite side to the one or more first locking portions 341. Each second locking portion 342 is provided on the rotating shaft portion 340 so as to protrude on the opposite side of the flat plate 330 from the rotating shaft portion 340 in a direction intersecting a plane including the two second support posts 313 and the two first support posts 312 (see FIGS. 31 and 32). Each second locking portion 342 is provided so that the rotation of the flat plate 330 stops at a predetermined position when the state of (the flat plate 330 of) the surface handrail portion 301 is changed from the open state (see FIG. 31) to the closed state (see FIG. 32). Specifically, when the face handrail part 301 (flat plate 330 thereof) is changed from the open state (see FIG. 31) to the closed state (see FIG. 32), each second locking part 342 is fitted into the rotation stopper 332 provided on the main surface 331a of the stop plate part 331. As described above, the two member pieces 332a, 332b of the rotation stopper 332 have a portion where the width between the two member pieces 332a, 332b is narrower than the diameter of the second locking part 342. Therefore, when the state of the flat plate 330 is changed from the open state to the closed state, the second locking part 342 abuts at the portion where the distance between the two member pieces 332a, 332b of the rotation stopper 332 is narrowest. By further rotating the flat plate 330 to the closed state, a clicking sensation can be given to the operator.
[0137] When the flat plate 330 is in the closed state, each second locking portion 342 abuts against a portion of the corresponding rotation stop fitting 332 that is in contact with the main surface 331a of the stop plate portion 331, thereby stopping the rotation of the flat plate 330 and fixing the state (closed state) of the flat plate 330. In addition, when changing the state of the flat plate 330 from the open state to the closed state, the operator can feel a click, so that the flat plate 330 can be reliably put into the closed state.
[0138] Furthermore, as described above, the face handrail section 301 is detachable from the two second supports 313. Therefore, when the face handrail section 301 is detached from the two second supports 313 in the auxiliary device 300, it can be used in the same manner as the usage shown in Fig. 21. Alternatively, by detaching the face handrail section 301 from the two second supports 313 in the auxiliary device 300 and providing a rod-shaped connecting section instead of the rotating shaft section 340, the auxiliary device 300 can be used in the same manner as the third auxiliary device 1003 shown in Fig. 3D.
[0139] When viewed from the direction in which the two second supports 313 are arranged, the two second supports 313 and the two first supports 312 do not have any parts that protrude from a plane that includes the two second supports 313 and the two first supports 312. Therefore, when the auxiliary device 300 is placed in a hallway or the like, the auxiliary device 300 can be placed closer to the wall. In other words, the auxiliary device 300 can occupy a larger space. In other words, the installation location of the auxiliary device 300 can be made more space-saving.
[0140] Furthermore, when viewed from the direction in which the two second supports 313 are arranged, the flat plate 330 is positioned in front of the two second supports 313 and the two first supports 312, so the user can open and close the flat plate 330 in front of the two second supports 313 and the two first supports 312.
[0141] Furthermore, the user can use the second support 313 and the handrail 310 as a handrail when walking. That is, the assist device 300 can be used as a handrail device of the present disclosure.
[0142] (4.8) Variation 8 In the above embodiment and modified examples 1 to 7, the connecting parts of the handrail device (for example, connecting parts 311a and 311b in modified example 7) are configured to have a linear shape, but are not limited to this configuration. The connecting parts may also have a curved shape (bent shape).
[0143] A handrail device 400 according to Modification 8 will be described below with reference to FIGS.
[0144] 33, the handrail device 400 includes a base 11, one or more (two in the illustrated example) first support posts 412 protruding upward from the base 11, one or more (two in the illustrated example) second support posts 413, a first handrail 410, and a second handrail 420. Each of the two second support posts 413 in FIG. 33 is configured to be connectable to the first handrail 410 and the second handrail 420.
[0145] In the handrail device 400, when viewed from the direction in which the two second supports 413 are aligned, the two second supports 413 and the two first supports 412 are provided along a direction that intersects (is perpendicular to) the base 11. In other words, when viewed from the direction in which the two second supports 413 are aligned, the two second supports 413 and the two first supports 412 do not have any parts that protrude beyond a plane that includes the two second supports 413 and the two first supports 412.
[0146] As shown in FIGS. 33 and 34, the first handrail 410 has a connecting portion 410a. The connecting portion 410a of the first handrail 410 is formed in a curved shape. Specifically, when viewed from a direction perpendicular to a plane including the two second posts 413, the connecting portion 410a of the first handrail 410 is formed in a curved shape (see FIGS. 33 and 34). More specifically, the connecting portion 410a of the first handrail 410 is formed so that the height from the base 11 to the center of the connecting portion 410a of the first handrail 410 is the greatest, and the height from the base 11 decreases as it approaches the end. A first circular plate portion 421 and a second circular plate portion 422 facing each other are provided at both ends of the connecting portion 410a of the first handrail 410. Furthermore, both ends of connecting portion 410a of first handrail 410 have cylindrical shaft portions that connect first circular plate portion 321 and second circular plate portion 422. First circular plate portion 421 corresponds to first circular plate portion 183a shown in Modification 2, and second circular plate portion 422 corresponds to second circular plate portion 183b shown in Modification 2. Furthermore, the shaft portion that connects first circular plate portion 421 and second circular plate portion 422 corresponds to shaft portion 183c shown in Modification 2.
[0147] Furthermore, as shown in FIGS. 33 and 34 , the first handrail 410 has one or more (two in the illustrated example) handrail portions 410b, which correspond to the handrail 13 described in the embodiment. The two handrail portions 410b correspond one-to-one to the two second support posts 413. The two handrail portions 410b are supported by the corresponding second support posts 413. The handrail portion 410b is formed in a curved rod shape when viewed from a direction perpendicular to a plane including the two second support posts 413. One end of the curved rod is connected to the second support post 413, and the other end is connected to the connecting portion 410a. Here, the radius of curvature of the curved rod is, for example, 80 mm (R80). Note that this value is an example and is not intended to be limiting. By increasing the radius of curvature, it is easier for the user to grasp the handrail portion 410b from end to end. That is, the handrail portion 410b has a large radius of curvature, making it user-friendly.
[0148] 33 and 34, the second handrail 411 has a connecting portion 411a. The connecting portion 411a of the second handrail 411 is formed in a curved shape. Specifically, the connecting portion 411a of the second handrail 411 is formed so that the height from the base 11 to the center of the connecting portion 411a of the second handrail 411 is the greatest, and the height from the base 11 decreases as it approaches the end.
[0149] 33 and 34, the second handrail 411 has one or more (two in the illustrated example) portions 411b. The two portions 411b of the second handrail 411 correspond one-to-one to the two second support posts 413. The two portions 411b are supported by the corresponding second support posts 413.
[0150] The handrail device 400 is configured to be connectable to other handrail devices. For example, the handrail device 400 is connected to the handrail device 1E shown in Fig. 29. The handrail device 400 is connected to the handrail device 1E via the handrail 200 and the connecting portion 184 shown in Modification 7.
[0151] When connecting the handrail device 400 to another handrail device (for example, the handrail device 1E shown in FIG. 29), the connecting portion 184 is connected to the shaft portion that connects the first circular plate portion 421 and the second circular plate portion 422 (see FIG. 35). The connecting method is the same as the method for connecting the second connecting portion 184 to the first connecting portion 183, so a description thereof will be omitted here.
[0152] By connecting the connecting portion 184 to the shaft portion that connects the first circular plate portion 421 and the second circular plate portion 422, the shaft portion can be rotated as the center of the rotation axis. In other words, the shaft portion that connects the first circular plate portion 421 and the second circular plate portion 422 and the connecting portion 184 can also be said to be a hinge portion.
[0153] When the handrail device 400 is not to be connected to another handrail device, a separable annular part 420 is attached to the shaft portion connecting the first circular plate portion 421 and the second circular plate portion 422 (see FIG. 33, etc.).
[0154] Furthermore, the handrail device 400 is configured to be usable as the above-mentioned second auxiliary device 1002 by attaching an openable and closable face handrail section 450. The face handrail section 450 is configured to be detachable from the two second posts 313.
[0155] 36 to 39, the surface handrail part 450 has a flat plate 451, a handle part 452, a rotating shaft part 453, and a pair of mounting parts 454, 455. The main surface 451a of the flat plate 451 is substantially rectangular. The handle part 452 is provided in an inverted U shape so as to protrude from the main surface 451a of the flat plate 451 and along the arrangement direction of the two second posts 413 when the surface handrail part 450 is attached to the handrail device 400.
[0156] The rotation shaft 453 controls the rotation of the flat plate 451. The rotation shaft 453 is provided on the opposite side of the main surface 451a of the flat plate 451 in the thickness direction of the flat plate 451, along the arrangement direction of the two second posts 413 when the surface handrail part 450 is attached to the handrail device 400. The rotation shaft 453 is configured to rotate the flat plate 451 from a closed state (see FIGS. 38 and 39) to a position (see FIGS. 36 and 37) where the flat plate 451 is in an open state (for example, approximately 90 degrees).
[0157] A pair of mounting portions 454, 455 are attached to both ends of the rotating shaft portion 453 in a one-to-one relationship. The pair of mounting portions 454, 455 correspond one-to-one to the two second support posts 413. Each of the mounting portions 454, 455 has a first portion 460, a second portion 461, and a third portion 462. The first portion 460 is attached to the rotating shaft portion 453. The third portion 462 has a through hole. The second portion 461 connects the first portion 460 and the third portion 462. At least one of the mounting portions 454, 455 has a thumbscrew 463. In Modification 8, the mounting portion 454 has the thumbscrew 463. The thumbscrew 463 is tightened to fix the surface handrail portion 450 to the handrail device 400.
[0158] When attaching the surface handrail section 450 to the handrail device 400, first, both the first handrail 410 and the second handrail 411 are removed from the second support pole 413. Then, the second support pole 413 is inserted through the through-holes in the third parts 462 of the mounting sections 454, 455, thereby attaching the surface handrail section 450 to the handrail device 400. Finally, the first handrail 410 is attached to the second support pole 413. The user secures the surface handrail section 450 to the handrail device 400 by tightening the thumb screws 463.
[0159] Furthermore, the handrail device 400 equipped with the surface handrail portion 450 is configured to be connectable to other handrail devices. For example, the handrail device 400 is connected to the handrail device 1E. The handrail device 400 equipped with the surface handrail portion 450 is connected to the handrail device 1E via the handrail 200 and the connecting portion 184 shown in Modification 7 (see FIG. 40).
[0160] When connecting the handrail device 400 equipped with the surface handrail portion 450 to another handrail device (for example, the handrail device 1E shown in FIG. 29), the connecting portion 184 is connected (see FIG. 35) to the shaft portion connecting the first circular plate portion 421 (see FIG. 33) and the second circular plate portion 422 (see FIG. 33). The connecting method is the same as the method for connecting the second connecting portion 184 to the first connecting portion 183 described in Modification 2, so a description thereof will be omitted here.
[0161] In the eighth modification, the face handrail section 450 is detachable from the two second supports 413. Therefore, when the face handrail section 450 is detached from the two second supports 313 in the handrail device 400, it can be used in the same manner as the usage shown in Fig. 21. Furthermore, when the face handrail section 450 is attached to the handrail device 400, it can be used in the same manner as the second auxiliary device 1002.
[0162] When viewed from the direction in which the two second supports 413 are arranged, the two second supports 413 and the two first supports 412 do not have any parts that protrude from a plane that includes the two second supports 413 and the two first supports 412. Therefore, when the handrail device 400 is placed in a hallway or the like, the handrail device 400 can be placed closer to the wall. In other words, the handrail device 400 can be placed in a larger space. In other words, the installation location of the handrail device 400 can be made more space-saving.
[0163] Furthermore, when viewed from the direction in which the two second supports 413 are arranged, the flat plate 451 is positioned in front of the two second supports 413 and the two first supports 412, so the user can open and close the flat plate 330 in front of the two second supports 413 and the two first supports 412.
[0164] Furthermore, connecting portion 410a of first handrail 410 and connecting portion 411a of second handrail 411 are formed in a curved shape. Therefore, connecting portion 410a of first handrail 410 or connecting portion 411a of second handrail 411 are structured to be easy to grip for users of handrail device 400. In particular, connecting portion 410a of first handrail 410 and connecting portion 411a of second handrail 411 are formed in a curved shape, which fits the angle of the arms when held with both hands.
[0165] Furthermore, by forming the connecting portion 410a of the first handrail 410 and the connecting portion 411a of the second handrail 411 in a curved shape, the connecting portions 410a, 411a are rounded, which makes them look better than if the connecting portions were formed in a straight line.
[0166] (4.9) Variation 9 Devices such as the second auxiliary device 1002 that assist a user in standing up from a sitting position may not have components (first circular plate portion 421, second circular plate portion 422, and shaft portion connecting the first circular plate portion 421 and the second circular plate portion 422) for connecting to other devices (for example, the handrail device 1E shown in Figure 29) as shown in variants 7 and 8.
[0167] 41A and 41B to the second auxiliary device 1002 that cannot be connected to other devices, it becomes possible to connect the second auxiliary device 1002 that could not be connected to other devices to the other device. For example, the pad member 500 is attached to at least one portion 550 of a pair of portions 550 that are formed by bending a member according to the connection mode.
[0168] As shown in Fig. 41B, the pad member 500 has a first circular plate portion 511, a second circular plate portion 522, and a shaft portion that connects the first circular plate portion 511 and the second circular plate portion 512. When connecting the second auxiliary device 1002 to another handrail device, the connecting portion 184 is connected to the shaft portion that connects the first circular plate portion 511 and the second circular plate portion 512 (see Figs. 41A and 41B). The connecting method is the same as the method of connecting the second connecting portion 184 to the first connecting portion 183 described in Modification 2, so a description thereof will be omitted here.
[0169] By attaching the pad member 500 to the second auxiliary device 1002, which does not have a member for connecting to another device, it becomes possible to connect the second auxiliary device 1002 to another device (e.g., handrail device 1E) via the connecting portion 184 and handrail 200 shown in variant example 7, as shown in FIG. 41A.
[0170] (4.10) Variation 10 In the connecting support 18 shown in Modification 2 (see, for example, FIG. 19), the shaft 183c of the connecting support 18 and the first and second connecting members 184a and 184b function as hinges. Therefore, the connecting support 18 shown in Modification 2 may be installed in a location where a user walking using the handrail device 1 turns, that is, may be applied to a corner-mounted handrail device. For example, FIG. 42 shows an example in which the handrail device 400 shown in Modification 8 and another device (for example, handrail device 1E) are connected via a corner-mounted handrail device having the connecting support 18.
[0171] Furthermore, the connecting support 19 shown in Modification 3 may also be applied to a corner-mounted handrail device, since the shaft 193a and the third part 194c of the connecting support 19 function as a hinge.
[0172] (4.11) Variation 11 Modifications are listed below. The modifications described below can be applied in appropriate combination with the above-described embodiment.
[0173] In the above embodiment, the edge portion 102 has a configuration including the recessed portion 126, but is not limited to this configuration. The edge portion 102 does not have to have the recessed portion 126. In other words, it is sufficient that the upper surface 121 of the edge portion 102 is formed smoothly when the base 11 is installed.
[0174] In the above embodiment, the edge portion 102 is configured to be provided around the entire periphery of the peripheral portion 111 of the plate 101, but is not limited to this configuration. The edge portion 102 may be provided on a part of the peripheral portion 111 of the plate 101.
[0175] In the above embodiment, the handrail device 1 does not necessarily have to include the edge 102 of the base 11. That is, the handrail device 1 may include at least the plate 101, the support 12, and the handrail 13, and may be configured to be connectable to an auxiliary device. In this case, the handrail device 1 can be easily installed. In addition, the handrail device 1 looks good when installed.
[0176] In the above embodiment, when the base 11 is not installed, the maximum length L1 of the recessed portion 126 along the thickness direction D1 is longer than the length L2 of the second portion 124 along the thickness direction D1. However, this configuration is not limited to this. When the base 11 is not installed, the maximum length L1 of the recessed portion 126 along the thickness direction D1 may be shorter than the length L2 of the second portion 124 along the thickness direction D1. Even when the maximum length L1 is shorter than the length L2, the upper surface 121 of the edge portion 102 can be made to have a more gentle slope when the base 11 is installed. This reduces the possibility of the adhesion between the lower surface 113 of the plate 101 and the second portion 124 peeling off when the third portion 125 is deformed when the base 11 is installed in an installation location.
[0177] (summary) As described above, the handrail device (1; 1A; 1B; 1C; 1D; 400) of the first aspect comprises a base (11), a support post (12) protruding upward from the base (11), and a handrail (13) supported by the single support post (12). The base (11) has a plate-like plate (101) and an edge portion (102) provided on at least a portion of the peripheral edge portion (111) of the plate (101). The edge portion (102) is formed so that the upper surface (121) of the edge portion (102) has a gentle slope when the base (11) is installed.
[0178] According to this configuration, the edge portion (102) is formed so that the upper surface (121) of the edge portion (102) has a gentle slope when the base (11) is installed, thereby reducing the possibility of the user tripping over the peripheral edge portion (111) of the base (11).
[0179] In the handrail device (1; 1A; 1B; 1C; 1D; 400) of the second aspect, in the first aspect, the edge portion (102) has a first portion (123) and a second portion (124) that sandwich the plate (101), and a third portion (125) that connects the first portion (123) and the second portion (124). The first portion (123) is in contact with a portion of the upper surface (112) of the plate (101). The second portion (124) is in contact with a portion of the lower surface (113) of the plate (101). The third portion (125) has a recessed portion (126) along the thickness direction (D1) from the lower surface (113) of the plate (101) toward the upper surface (112) of the plate (101). When the base is not installed, the maximum length (L1) of the recessed portion (126) along the thickness direction (D1) is longer than the length (L2) of the second portion (124) in the thickness direction (D1).
[0180] According to this configuration, when the plate (101) is installed, the radius of curvature of the upper surface (121) of the edge portion (102) can be increased, so that the upper surface (121) of the edge portion (102) can have a more gentle slope.
[0181] In the third embodiment of the handrail device (1; 1A; 1B; 1C; 1D; 400), in the second embodiment, when the base (11) is not installed, the tip (127) of the third portion (125) is located at a lower position than the second portion (124).
[0182] With this configuration, the third portion (125) can be deformed so that the tip portion (127) is located lower than the second portion (124) when the base (11) is not installed at the installation location, and the tip portion (127) is located at the same position as the second portion (124) when the base (11) is installed at the installation location. This allows the upper surface (121) of the edge portion (102) to have a gentle slope.
[0183] In the handrail device (1; 1A; 1B; 1C; 1D; 400) of the fourth aspect, in any one of the first to third aspects, the edge portion (102) is provided around the entire periphery of the peripheral portion (111) of the plate (101).
[0184] This configuration can further reduce the possibility of the user tripping over the peripheral edge (111) of the base (11).
[0185] In the handrail device (1; 1C; 1D; 400) of the fifth aspect, in any one of the first to fourth aspects, the handrail (13) is configured to be connectable to an assisting device that assists the user's movements.
[0186] This configuration allows the user to perform successive movements smoothly. Also, since the support posts (12) do not need to be fixed to the floor and ceiling, the length of the support posts can be shorter than in the past. Therefore, when the handrail device (1) is installed, the appearance can be improved.
[0187] In the handrail device (1; 1C; 1D; 400) of the sixth embodiment, in the fifth embodiment, the handrail (13) is connected to the assist device via a connecting part (14) that is used as a handrail when walking.
[0188] This configuration allows for a longer distance for walking assistance.
[0189] In the seventh aspect of the handrail device (1; 1C; 1D; 400), in the fifth or sixth aspect, the assisting device includes at least one of a device that assists the user in walking when walking over a step and a device that assists the user in standing up.
[0190] According to this configuration, when at least one of the movement at the step and the standing-up movement is consecutively performed with the walking movement, the user can smoothly perform the consecutive movements.
[0191] In the handrail device (1; 1A; 1B; 1C; 1D; 400) of the eighth aspect, in any one of the first to seventh aspects, the plate (101) has a plurality of mounting portions (103) for mounting the support poles (12). The support poles (12) are mounted to one selected mounting portion (103) from the plurality of mounting portions (103).
[0192] With this configuration, the mounting location of the support pole (12) can be changed depending on the purpose of use.
[0193] In the handrail device (1; 1A; 1B; 1D; 400) of the ninth aspect, in any one of the first to eighth aspects, the handrail (13) is configured to have a gentle slope.
[0194] This configuration makes it easier for the user to hold on to the handrail (13).
[0195] The base (11) of the tenth aspect is used in the handrail device (1; 1A; 1B; 1C; 1D) of any one of the first to ninth aspects.
[0196] This configuration reduces the possibility of the user tripping over the peripheral edge (111) of the base (11).
[0197] The handrail (13) of the eleventh aspect is used in the handrail device (1; 1A; 1B; 1C; 1D) of any one of the first to ninth aspects.
[0198] This configuration reduces the possibility of the user tripping over the peripheral edge (111) of the base (11).
[0199] The support (12) of the twelfth aspect is used in the handrail device (1; 1A; 1B; 1D) of any one of the first to ninth aspects.
