Description

  The present invention relates to a walking support device that can be easily installed on a handrail or a wall surface and functions as a walking aid.

As conventional techniques, Patent Documents 1 and 2 below disclose a free handrail and a stair lift support device, respectively.
JP 2004-244823 A JP-A-5-137760

  The handrail according to Patent Document 1 is configured such that a person who wants to climb a stairs, for example, grips a handrail that is pivotally connected to an attachment portion that can be attached to a wall surface. For this reason. If the weight of the person who wants to climb the stairs is added to the handrail as a torque, this reaction force must be received by the wall surface, so when installing the universal handrail in a house, etc. Physical strength is required.

  In addition, the stair lift support device according to Patent Document 2 has a handle attached to a route member installed along the slope of the staircase, and the handle extends along the route member in a state where the end of the handle is lifted from the route member. When a person who can move and wants to climb the stairs presses the end of the handle against the path member while holding the handle, the handle is fixed to the path member. In this state, a person who wants to climb the stairs can move forward while supporting the handle. If the end of the handle is lifted from the path member again, the handle can be moved to the front of the person who is going up the stairs. By repeating this operation, anyone who wants to climb the stairs can move with the handle.

  However, when a plurality of persons use the stair lift support device sequentially, the handle also moves together with the person who uses the stair lift support device in advance. I will go far away. For this reason, it is difficult for another person to use immediately after the preceding person.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a walking support device that takes into consideration the ease of use by a large number of people without selecting the conditions of the installation location.

  The walking support device according to the present invention is such that a main body that can be attached to a wall surface or a handrail installed on the wall surface, and a handle portion provided at a tip can approach the wall surface, or the handle portion can turn in a direction away from the wall surface. A movable arm supported by the main body, biasing means for biasing the movable arm in a direction in which the handle portion approaches the wall surface, and the movable arm in a posture in which the handle portion is separated from the wall surface. And a stopper capable of positioning.

  The walking support device according to the present invention is attached to a wall surface or a handrail installed on the wall surface, and a plurality of main bodies that are separated from each other in a direction along the wall surface or the handrail, and a handle portion provided at a tip approach the wall surface. Or a plurality of movable arms supported by each of the main bodies and a plurality of the movable arms so as to be pivotable in a direction away from the wall surface, and urging the grip portions in a direction in which the handle portions approach the wall surface. An urging means and a stopper capable of positioning each of the movable arms in a posture in which each of the grip portions is separated from the wall surface are provided.

  Furthermore, the walking support apparatus according to the present invention is characterized in that the main body is provided with guide means for supporting the movable arm so as to be slidable in a direction along the wall surface or the handrail.

  Further, the urging means includes an elastic body having one end and the other end, and a traction portion for connecting one end of the elastic body is provided at a position eccentric from the turning center of the movable arm. A fixing member for fixing the other end of the body is provided.

  According to the walking support apparatus according to the present invention, the main body can be attached to at least one of the wall surface or the handrail, so that it can be installed in almost all houses and is not accompanied by a large-scale remodeling work. There are advantages. In particular, when the main body of the walking support device is attached to both the wall surface and the handrail, the main body of the walking support device also serves as a reinforcing material that suppresses bending of the handrail. Further, since the movable arm is urged by the urging means in a direction in which the handle portion approaches the wall surface or the handrail, the movable arm protrudes unnecessarily from the handrail or the wall surface when no one uses the walking support device. There is an advantage that the movable arm does not interfere with walking.

  A person who uses the walking support device (hereinafter referred to as “user”) pulls the movable arm in front of the user while holding the movable arm by hand. As a result, the movable arm turns against the urging force of the urging means, and the movable arm is positioned by the stopper when the handle portion is separated from the handrail. In this state, even if the weight of the user is applied as a torque to the movable arm, the movable arm does not further turn.

  Therefore, even if the user pulls the handle part of the movable arm in front of himself / herself in the process of climbing the stairs etc., the movable arm can maintain its posture away from the wall surface. The grip portion of the handrail does not face the other side in the longitudinal direction of the handrail. Moreover, since a wall surface, a handrail, or both of them can be selected as a support for receiving the above torque, various mounting structures can be realized without depending only on the strength of the wall surface as in the past. it can.

  Moreover, according to the walking support device, the reaction force generated in the biasing means pushes up the user's hand through the movable arm in the process of the user climbing the stairs etc., so that the user can move up the stairs etc. Can be subsidized.

  Moreover, when the said walk assistance apparatus is provided with the guide means which supports a movable arm to a main body so that sliding is possible, in addition to said turning operation | movement, a movable arm can also be slid in the direction along a wall surface or a handrail. As a result, a force that pushes up the user's hand as a reaction force is generated on the movable arm that slides against the biasing force of the biasing means. Continue to subsidize the movement of climbing etc.

  Two or more walking support devices may be attached to one handrail 3. Alternatively, two or more walking support devices may be mounted side by side on the wall surface. In this case, if the plurality of main bodies are arranged so as to be separated from each other in the direction along the wall surface or the handrail, the individual walking support devices will not move. When the user who completes the use of the walking support device, the movable arm returns to the state in which the handle portion approaches the wall surface or the handrail. Subsequent users can immediately grip the handle of the movable arm with their hands, so immediately after the preceding user uses the walking support device, the subsequent user can use the same walking support device without waiting for the same. can do.

  In addition, when a traction part that connects one end of the elastic body is provided at a position that is eccentric from the turning center of the movable arm, a fixing member that fixes the other end of the elastic body is provided in the main body of the walking support device. When a person begins to pull the movable arm toward him, the elastic body extends relatively slowly, but as the movable arm turns and the handle part moves away from the handrail, the pulling part stretches the elastic body relatively large. . For this reason, the movable arm can be easily moved by a light operation of the user. However, when the weight of the user is applied as a torque to the movable arm, the reaction force generated in the urging means is applied to the user's hand via the movable arm. Is strongly pushed up, so that the user can subsidize the operation of climbing stairs.

  A walking support apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the following, elements that are essential to the present invention and “attachment” or “fixation” between members constituting the present invention will be firmly formed using bolts unless otherwise specified, and description thereof will be omitted. .

  Based on FIG. 1 to FIG. 3, the principle of the walking support device 1 which is the best embodiment will be described. As shown in FIGS. 1 and 2, the walking support device 1 is supported by the main body 4 so that the main body 4 attached to the wall surface 2 and the handle portion 5 at the tip can freely turn in the direction indicated by the arrows Ra and Rb. The movable arm 6, a pair of urging means 7 for urging the movable arm 6 in the direction indicated by the arrow Ra or the arrow La, a pair of stoppers 8, which will be described later, and the handle portion 5 are movable in a posture away from the wall surface 2. And a pair of guide means 9 for slidably guiding the arm 6 in the direction indicated by the arrows La and Lb.

  Hereinafter, for example, a slope, a stepped portion, or a staircase is collectively referred to as a “staircase etc.”, and a usage example of the walking support device 1 when the user climbs the staircase etc. from the other 21 side of the wall surface 2 toward the one 20 side. Is described. Further, when attaching the main body 4 to the wall surface 2, the main body 4 is illustrated so that one end portion of the main body 4 directed to one side 20 of the wall surface 2 is higher than the other end portion of the main body 4 directed to the other side 21 of the wall surface 2. It is preferable to adopt an inclined posture as shown in FIG.

  The movable arm 6 has a gate-like shape as a whole, and its tip (head) serves as a handle portion 5 and a reinforcing member 60 is bridged between both leg portions. Furthermore, the extension part 61 is provided in both the leg parts of the movable arm 6, respectively. Each guide means 9 is rotatably supported by the shaft support member 11 attached to the outer surface of the extending portion 61 on one side of the movable arm 6 and the shaft support member 11 as shown in FIGS. Two rollers 94, 95 are provided, and one end portion 91 is bent at a right angle to the wall surface 2, and the other end portion 92 is provided with a substantially L-shaped guide groove rail 93 extending along the wall surface 2. The two rollers 94 and 95 are inserted into the groove of the guide groove rail 93 and can freely roll along the one end 91 or the other end 92.

  As shown in FIGS. 1 and 2, each urging means 7 includes a flexible checker 71 having a distal end 70 connected to the extending portion 61 or the shaft support member 11, and a main body 4 via a bracket 72. The core material 73 is energized by a spring not shown in the figure so that the core material 73 is wound around the attached core material 73 and rotates in the direction in which the flexible core 71 is wound up. The pair of stoppers 8 are respectively fixed to the terminal ends of the other end 92 of the guide groove rail 93. Further, the pair of stoppers 8 may be fixed to the wall surface 2 via the stays 80, respectively.

  When no one uses the walking support device 1, the movable arm 6 is urged by the elastic force of the urging means 7, and as shown by the solid line in FIG. maintain. For this reason, the movable arm 6 does not protrude from the wall surface 2 unnecessarily, and the movable arm 6 does not interfere with walking. In this state, if the movable arm 6 is pulled in front of the user (in the direction of the arrow Rb) while the user grips the handle portion 5 facing the one side 20 of the wall surface 2 with the hand, the movable arm 6 is attached. It turns against the elastic force of the biasing means 7. In this process, the two rollers 94 and 95 roll as follows.

  That is, when the movable arm 6 takes a posture in which the handle portion 5 approaches the wall surface 2, the two rollers 94 and 95 are accommodated in one end portion 91 of the guide groove rail 93, as shown by a solid line in FIG. One roller 94 is located at the corner between one end 91 and the other end 92. In this state, when the movable arm 6 starts to turn in the direction of the arrow Rb with the vicinity of the extension portion 61 as a fulcrum, one roller 94 first rolls in the direction of the arrow Lb along the other end portion 92, and at the same time, the other The roller 95 rolls along the one end portion 91 in a direction away from the wall surface 2. The two rollers 94 and 95 in this process are represented by dots in FIG.

  Then, as shown in FIG. 2, when the other roller 95 reaches the corner of one end 91 and the other end 92 (position overlapping one roller 94 shown), the movable arm 6 As shown by the phantom line, the grip portion 5 is in a posture away from the wall surface 2, and the grip portion 5 is protruded from the wall surface 2 in a right angle direction. Further, when the user puts weight on the hand holding the handle portion 5 while climbing the stairs or the like, the two rollers 94 and 95 further roll in the direction of the arrow Lb along the other end portion 92 of the guide groove rail 93. Since the movable arm 6 moves, the movable arm 6 slides in the direction of the arrow Lb while keeping the grip portion 5 away from the wall surface 2. Finally, when one roller 94 hits the stopper 8, the movable arm 6 is positioned.

  In this way, the range in which the movable arm 6 can slide in the direction of the arrow Lb is limited by the stopper 8, and the movable arm 6 can be stopped at a desired position. Therefore, when the user pulls the handle portion 5 toward himself / herself In addition, even if the weight of the user is added to the movable arm 6, the movable arm 6 does not move carelessly. Therefore, the user can climb the stairs while relying on the movable arm 6 as a support. Moreover, in the process in which the user climbs the stairs etc., the urging means 7 plays the role of pushing up the user's hand to one side 20 of the wall surface 2 via the movable arm 6, so that the user climbs the stairs etc. Can be subsidized.

  In the above description, an example in which one walking support device 1 is attached to the wall surface 2 has been described, but two or more walking support devices 1 may be attached to the wall surface 2. In this case, if the plurality of main bodies 4 are arranged on the wall surface 2 so as to be separated from each other in the direction along the inclination of a staircase or the like, the following advantages are obtained. That is, since each walking support apparatus 1 does not move with respect to the wall surface 2, when a plurality of users sequentially climb stairs or the like, when the preceding user finishes using the walking support apparatus 1 Thus, the movable arm 6 returns to the state shown by the solid line in FIG. Subsequent users can immediately grasp the grip portion 5 of the movable arm 6 with their hands, so immediately after the preceding user uses the walking support device 1, the subsequent user also waits for the same walking support device 1. Can be used without

  Based on FIGS. 4-6, the walk assistance apparatus 10 which is other embodiment is demonstrated. In the following, elements common to the first embodiment are denoted by the same reference numerals, and description or illustration thereof is omitted.

  As shown in FIG. 4, the walking assist device 10 includes a main body 4 attached to the wall surface 2 and a movable arm 6 that can freely turn in a direction in which a handle portion 5 at the tip is pointed by a bearing portion 90 with arrows Ra and Rb. And a pair of urging means 17 for urging the movable arm 6 in the direction indicated by the arrow Ra, and a pair of stoppers for positioning the movable arm 6 in a posture away from the handrail 3 as shown in FIG. 8.

  As shown in FIG. 6, the handrail 3 is attached to the wall surface 2 by a metal fitting 32 in an inclined posture in which one side 30 in the longitudinal direction is raised from the other side 31. An example of use when climbing stairs or the like from the other 31 side of the handrail 3 toward the one 30 will be described.

  A handrail joining member 43 is attached to the main body 4 via two connecting members 41 and 42. One connecting member 41 overlaps the inside of the other connecting member 42, and is coupled to the other connecting member 42 by a bolt 45 that passes through the long hole 44 of the one connecting member 41. If the bolt 45 is loosened, the connecting members 41 and 42 can be relatively moved in the longitudinal direction of the long hole 44. Therefore, the dimension from the main body 4 to the handrail joining member 43 can be adjusted according to the distance from the wall surface 2 to the handrail 3. The handrail joining member 43 is fixed to the handrail 3 by holding the handrail 3 inside the two U bolts 46.

  According to the walking support device 10, the main body 4 may be attached to the wall surface 2, the main body 4 may be attached to the handrail 3 via the handrail joining member 43, or the main body 4 is attached to the wall surface 2 and the handrail joining member 43. May be fixed to the handrail 3. Thus, since the main body 4 can be attached to at least one of the wall surface 2 or the handrail 3, the walking support device 10 is installed on the stairs of most buildings regardless of whether the wall surface 2 or the handrail 3 is present. In addition, the installation does not involve any major remodeling work. In particular, when the main body 4 is attached to both the wall surface 2 and the handrail 3, the main body 4 also serves as a reinforcing material that suppresses bending of the handrail 3.

  As shown in FIGS. 4 and 6, the movable arm 6 spans a shaft body 62 between its both leg portions. The bearing portion 90 is configured such that the shaft body 62 of the movable arm 6 is rotatably inserted into the cylindrical body 12 fixed to the handrail joining member 43 with two U bolts 91. In addition to a long coil spring having one end 171 and the other end 172, any linear elastic body such as rubber can be applied to each urging means 17. Furthermore, a traction portion 63 connected to one end 171 of the urging means 17 is provided on each leg portion of the movable arm 6 at a position eccentric from the bearing portion (turning center) 90. A fixing member 173 for fixing the other end 172 of the biasing means 17 is attached to the main body 4.

  The fixing member 173 hooks the other end 172 of the urging means 17 to the tip of an L-shaped bolt that is screwed into the main body 4. When the lock nut 174 is loosened and the fixing member 173 is rotated with respect to the main body 4, the dimension at which the tip of the fixing member 173 protrudes from the main body 4 can be adjusted. Thereby, the tension generated in the biasing means 17 can be appropriately increased or decreased. The individual stoppers 8 are metal fittings arranged on both sides of the main body 4.

  When no one uses the walking support device 10, the movable arm 6 is urged by the elastic force of the urging means 17 in the direction in which the handle portion 5 approaches the handrail 3, as shown in FIG. 6 does not protrude from the handrail 3 unnecessarily, and the movable arm 6 does not interfere with walking. In this state, when the user pulls the movable arm 6 in front of the user while holding the handle 5 of the movable arm 6 by hand, the movable arm 6 resists the elastic force of the biasing means 17. Turn.

  Then, as shown in FIG. 5, when the handle portion 5 is separated from the handrail 3, the pulling portion 63 of the movable arm 6 hits the stopper 8 and the movable arm 6 is positioned. In this state, when the user pulls the handle portion 5 of the movable arm 6 in front of himself / herself, even if the weight of the user is applied to the movable arm 6 as torque in the direction indicated by the arrow Rb, the movable arm 6 Will not turn further from the state of FIG. Therefore, the user can climb the stairs while relying on the movable arm 6 as a support. In addition, if the movable arm 6 is in the state shown in FIG. 5 while the user climbs the stairs or the like, the biasing means 17 moves the user's hand to the one 30 in the longitudinal direction of the handrail 3 via the movable arm 6. Since it keeps pushing up, the user can subsidize the operation of climbing stairs.

  Further, immediately after the user pulls the movable arm 6 toward himself / herself, the traction portion 63 is gradually displaced from the position shown in FIG. 4 in the direction of the arrow Lb. In accordance with this, the biasing means 17 starts to expand relatively slowly. Therefore, the user can easily turn the movable arm 6 with a light operation. Further, while the weight of the user is applied to the movable arm 6 as torque and the movable arm 6 reaches the state shown in FIG. Since the displacement is relatively fast in the direction of the arrow Lb, the urging means 17 is rapidly expanded to the length shown in FIG. In this state, the urging means 17 strongly pushes up the user's hand to the longitudinal one 30 of the handrail 3 via the movable arm 6, so that the user assists the operation of climbing the stairs as described above. be able to.

  Further, the movable arm 6 shown in FIG. 4 has a posture in which the handle portion 5 is slightly separated from the handrail 3. This is because tension is generated in the biasing means 17 even in the state shown in FIG. Therefore, in addition to the above coil spring as the urging means 17, as shown in FIG. 5, a torsion spring 177 for connecting one end 175 to an appropriate position of the movable arm 6 and pressing the other end 176 against the main body 4 is provided. You may provide in the bearing part 90. FIG. Accordingly, if the movable arm 6 in the state of FIG. 4 is further turned in the direction indicated by the arrow Ra, the handle portion 5 can always be brought into contact with the handrail 3 when no one is using the walking support device 10. . Alternatively, the coil spring may be omitted, and only the torsion spring 177 may be applied as the biasing means 17.

  In the above description, an example in which one walking support device 10 is attached to one handrail 3 has been described, but two or more walking support devices 10 may be attached to one handrail 3. In this case, if the plurality of main bodies 4 are arranged on one handrail 3 so as to be separated from each other in the longitudinal direction of the handrail 3, the following advantages are obtained. That is, since each walking support device 10 does not move with respect to the handrail 3, when a plurality of users sequentially climb stairs or the like, when a preceding user finishes using the walking support device 10 Thus, the movable arm 6 returns to the state shown in FIG. Subsequent users can immediately grip the grip portion 5 of the movable arm 6 with their hands, so immediately after the preceding user uses the walking support device 1, the subsequent user also waits for the same walking support device 10. Can be used without

  Moreover, you may make it the some movable arm 6 interlock | cooperate mutually by connecting each movable arm 6 of the some walk assistance apparatus 10 with a connecting rod. In this case, the stopper 8 or the urging means 17 do not need to be provided in all of the plurality of walking support devices 10, and may be provided in any one or more walking support devices 10.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the movable arm 6 does not need to have a gate shape, and the handle portion 5 may have a ring shape. Further, the handrail joining member 43 of the walking support device 10 may be omitted, and the main body 4 may be exclusively attached to the wall surface 2 as shown in FIG.

  The walking support device according to the present invention can be installed in a house, a hospital, a nursing facility, a nursing home, or the like.
