Description

  The present invention relates to a walking assistance device that assists walking of a physically handicapped person or an elderly person. More specifically, the present invention relates to a walking assistance device including a movable handrail that a pedestrian grips when walking.

  As a walking assist device in which a handrail that a handicapped person or an elderly person grips during walking is movable, there is a movement assist device disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-26254. For example, as shown in FIGS. 16 to 20, this movement assist device moves the handrail 104 along a traveling rail 103 fixed to a wall 102 (FIG. 16) or a ceiling 101 (FIG. 19). A slit 103 b is provided on the bottom surface 103 a of the traveling rail 103, and the connecting rod 105 is connected to the bottom surface of the slider 106 that moves in the traveling rail 103 through the slit 103 b. A large number of balls 107 are attached to the bottom and side surfaces of the slider 106 to enable the slider 106 to move within the traveling rail 103.

JP 2006-26254 A

  However, the above-described movement assist device has a structure in which the slider 106 moves in the traveling rail 103. In order to connect the connecting rod 105 to the slider 106, it is necessary to provide the traveling rail 103 with the slit 103. It was inferior in rigidity. For this reason, for example, when the handrail 104 is inclined and the slider 106 is inclined in the traveling rail 103, the bottom surface 103a of the traveling rail 103 provided with the slit 103b may be deformed.

  In addition, if the handrail has moved to a place away from the place where the person who is going to use it is located, there is no means for the person himself / herself to pull the handrail to the place where he / she is. It was difficult to use.

  An object of the present invention is to provide a walking assist device that can easily ensure the rigidity of a rail. Another object of the present invention is to provide a walking assistance device suitable for use by a plurality of persons.

  In order to achieve such an object, the walking assist device according to claim 1 includes a guide rail fixed to an upper part of a ceiling or a wall surface, a slider guided and moved by the guide rail, and a moving handrail suspended from the slider. The slider has a roller that rolls while sandwiching the outer peripheral surface of the guide rail.

  The guide rail is provided along the moving direction of the pedestrian. When the pedestrian moves while grasping the moving handrail, the roller sandwiching the outer peripheral surface of the guide rail rolls, and the slider moves while being guided by the guide rail. For this reason, the pedestrian can move together with the moving handrail while being held by the moving handrail within the range where the guide rail is provided. The roller of the slider has a structure that sandwiches the outer peripheral surface of the guide rail, and it is not necessary to provide a slit in the guide rail to reduce the rigidity, so that the rigidity of the guide rail can be increased. For this reason, even if the force which inclines to a slider acts, a guide rail is not deformed.

  According to a second aspect of the present invention, the walking assist device is provided at a location where the guide rail is interrupted in the fixed handrail facility, and is provided above the position where the ends of the interrupted fixed handrail facility are connected. For example, a fixed handrail facility is provided on a wall of a passage in a building, but the fixed handrail facility is also disconnected at a place where a wall is interrupted, such as a place where an entrance / exit is provided or a place where a passage intersects. A pedestrian who has traveled to the interrupted end through the fixed handrail facility can move to the end of the fixed handrail facility on the opposite side by moving while grabbing the moving handrail of the walking assist device.

  According to a third aspect of the present invention, there is provided a walking assistance device having a movement resistance adjusting means for increasing or decreasing the movement resistance force of the slider. Therefore, the force required to move the slider can be increased or decreased by adjusting the movement resistance adjusting means. As the movement resistance adjusting means, for example, means for increasing / decreasing the distance between the rollers that sandwich the outer peripheral surface of the guide rail, means for pressing the roller against the guide rail by the elastic force of the spring, and increasing / decreasing the elastic force of the spring, Means for attaching or decreasing the weight of the weight, means for inclining the guide rail, and the like are conceivable.

  According to a fourth aspect of the present invention, there is provided a walking assist device comprising a tilt preventing means for preventing the slider from tilting in the circumferential direction of the guide rail. The guide rail is fixed to a ceiling, a wall or the like by a fixture such as a stay. When the guide rail is long, it is necessary to fix the guide rail with a fixture. When the slider moves along the outer peripheral surface of the guide rail, if the slider is inclined in the circumferential direction of the guide rail, there is a possibility of interfering with a fixture on the way. By preventing the slider from tilting in the circumferential direction of the guide rail by the tilt prevention means, it is possible to prevent interference between the mounting tool in the middle of the guide rail and the slider. As the tilt preventing means, for example, it is conceivable to use a pipe or a square pipe having an elliptical cross section as a guide rail.

  According to a fifth aspect of the present invention, there is provided a walking assist device comprising height adjusting means for adjusting the height of the moving handrail. Therefore, the height of the moving handrail can be adjusted according to the pedestrian's physique and physical condition.

  According to a sixth aspect of the present invention, the walking assist device includes a linear member that is connected to the slider, extends along the guide rail, and hangs down from the vicinity of the end of the guide rail. When the walking assist device is continuously used in the same movement direction, the slider moves to the other end of the guide rail in the second use. In this case, when the pedestrian pulls the linear member, the slider can be drawn from the other end.

  According to a seventh aspect of the present invention, the walking assist device includes a weight provided at a hanging portion of the linear member. Therefore, it is possible to reduce the force required for the pedestrian to pull the slider. Further, since the linear member hangs down in a U-shape with the weight turned back, when the slider is moved by hand, the slider can be moved by half the moving amount of the slider.

  Further, the walking assist device according to claim 8 includes a return means for returning the slider to a specific end of the guide rail. Therefore, after the pedestrian grips the moving handrail and moves in the direction from the specific end of the guide rail toward the opposite end, when the hand is released from the moving handrail, the return means returns the slider to its original position (specific end). Automatically return to

  According to a ninth aspect of the present invention, in the walking assist device, the return means returns the slider to the lower end of the guide rail using gravity by inclining the guide rail. Therefore, after the pedestrian grips the moving handrail and moves from the lower end of the guide rail toward the higher end, when the hand is released from the moving handrail, the slider naturally moves to its original position (the lower one). Return to the end. Here, when the inclination angle of the guide rail is increased, the movement resistance force of the slider when used by a pedestrian increases. Moreover, if the inclination angle of the guide rail is reduced, the return of the slider becomes unstable. For this reason, the inclination angle of the guide rail is appropriately determined in consideration of the physical condition of the pedestrian to be used and the certainty of the return of the slider.

  According to a tenth aspect of the present invention, the restoring means includes an elastic member that is elastically deformed in accordance with the movement of the slider. Therefore, when the pedestrian grips the moving handrail and moves in a direction from a specific end of the guide rail toward the opposite end, the elastic member is elastically deformed and an elastic force is accumulated. Thereafter, when the pedestrian releases his hand from the moving handrail, the elastic force stored in the elastic member is released, and the slider is returned to the original position (specific end).

  The walking assist device according to claim 11 is provided with one slider on which one of the guide rails is suspended on one side half and the other side half of the guide rail and moves the two sliders. A connection mechanism is provided for connection so that the directions are reversed, and the connection mechanism is pulled by the movement of one slider and pulls the other slider in a direction opposite to the movement direction.

  Therefore, when one slider is moved from one end of the guide rail toward the center, the coupling mechanism moves the other slider from the other end of the guide rail toward the center. When one slider is returned from the center of the guide rail toward one end, the coupling mechanism moves the other slider from the center of the guide rail toward the other end. This movement is the same when the other slider is moved instead of moving one slider. That is, the two sliders move toward each other toward the center of the guide rail or away from each other toward both ends of the guide rail by the action of the coupling mechanism.

  For this reason, when the pedestrian moves from one end of the guide rail toward the center while grasping a moving handrail suspended on one slider (hereinafter referred to as one moving handrail), the other slider is suspended. A moving handrail (hereinafter referred to as the other moving handrail) moves from the other end of the guide rail toward the center. The pedestrian then replaces the moving handrail gripped at the center of the guide rail. Thereafter, the pedestrian moves toward the other end of the guide rail while being held by the other moving handrail. At the same time, one handrail is returned from the center of the guide rail toward one end.

  The walking assist device according to claim 12 includes two sets each having a guide rail, a slider, a moving handrail, and a return means, and one set of guide rails is arranged in a state where one end is low, and the other set The pair of guide rails are arranged with the other end being low, and the pair of guide rails are arranged in a radial direction as viewed from above.

  Therefore, in the standby state, one set of moving handrails is moved to one end of the guide rail, and the other set of moving handrails is moved to the other end of the guide rail. Now, when a pedestrian moves from one end of the guide rail toward the other end, the pedestrian moves while grasping one set of moving handrails. When the pedestrian moves to the other end of the guide rail and then releases the moving handrail, the slider moves toward one end of the guide rail by gravity, and the moving handrail can be naturally returned to the original position. Similarly, when a pedestrian moves from the other end of the guide rail toward one end, the pedestrian moves while being gripped by the other set of moving handrails. When the pedestrian moves to one end of the guide rail and then releases the moving handrail, the slider moves toward the other end of the guide rail by gravity, and the moving handrail can be naturally returned to the original position. Since the guide rails of each set are arranged so as to be displaced in the radial direction when viewed from above, the movements of the moving handrails of each set do not interfere with each other.

According to a thirteenth aspect of the present invention, in the walking assist device, two sliders, each having a suspended handrail, are provided on one guide rail, two return means are provided, and one return means is provided at one end of the guide rail. The slider provided is returned to one end of the guide rail, and the slider provided on the other end side of the guide rail is returned to the other end of the guide rail by the other return means.

  Accordingly, in the standby state, a slider disposed on one end side of the guide rail (hereinafter referred to as one end side slider) is disposed at one end of the guide rail, and a slider disposed on the other end side (hereinafter referred to as the other end side slider) is guided. It has moved to the other end of the rail. Now, when a pedestrian moves from one end of the guide rail toward the other end, the pedestrian moves while grasping a moving handrail suspended by the one end side slider. By this movement, the elastic member of the return means connected to the one end side slider is elastically deformed and the elastic force is stored. When the pedestrian moves to the other end of the guide rail and then releases the moving handrail, the elastic force stored in the elastic member is released and the one end side slider is returned to the original position (one end of the guide rail). Similarly, when the pedestrian moves from the other end of the guide rail toward one end, the pedestrian moves while grasping the moving handrail suspended from the other end side slider. Due to this movement, the elastic member of the return means connected to the slider on the other end side is elastically deformed to store the elastic force. When the pedestrian moves to one end of the guide rail and then releases the moving handrail, the elastic force stored in the elastic member is released, and the other end side slider is returned to the original position (the other end of the guide rail).

  The walking assist device according to claim 1, further comprising: a guide rail fixed to an upper portion of the ceiling or the wall surface; a slider that moves while being guided by the guide rail; and a moving handrail that is suspended by the slider. Since it has a roller that rolls while sandwiching the outer peripheral surface, the pedestrian can move while grasping the moving handrail within the range where the guide rail is provided. Since the slider roller sandwiches the outer peripheral surface of the guide rail, the rigidity of the guide rail can be increased. For this reason, even if the force which inclines to a slider acts, a guide rail is not deformed.

  Further, in the walking assist device according to claim 2, the guide rail is provided at a place where the fixed handrail facility is interrupted, and is provided above the position where the end of the interrupted fixed handrail facility is connected.

  Hereinafter, the configuration of the present invention will be described in detail based on the best mode shown in the drawings.

  1 to 4 show a first embodiment of the walking assistance device of the present invention. The walking assist device includes a guide rail 1 fixed to a ceiling or an upper part of a wall surface, a slider 2 that moves while being guided by the guide rail 1, and a handrail 3 that is suspended by the slider 2, and the slider 2 is a guide rail. 1 has a roller 4 that rolls while sandwiching the outer peripheral surface of 1. In the present embodiment, the guide rail 1 is fixed to the upper wall surface 42.

  The guide rail 1 is, for example, an elliptical pipe having an elliptical cross-sectional shape. For example, the guide rail 1 is used by connecting a plurality of pipes. That is, the required length of the guide rail 1 can be ensured by connecting a plurality of pipes. For example, the guide rail 1 is fixed to the upper portion 42 of the wall surface, that is, a portion of the wall surface having a height that does not obstruct pedestrian traffic by three attachment tools 5. Each fixture 5 is fixed to a position where there is a strength member 46 (see FIG. 6 and the like) such as a beam, a girder, and a stud on the upper surface 42 of the wall. The guide rail 1 is provided with a plurality of screw holes for attaching the fixture 5 at a predetermined interval, and the mounting position of the fixture 5 can be changed. For this reason, the attachment position of the fixture 5 can be suitably selected according to the position of the strength members 46 such as beams, girders, and studs. The guide rail 1 is provided along the moving direction of the pedestrian.

  The slider 2 includes a slider body 6, an upper roller box 7 to which the upper roller 4 is attached, a lower roller box 8 to which the lower roller 4 is attached, and an arm 9 that extends toward the upper wall surface 42. . For example, two upper rollers 4 are attached to the upper roller box 7. Further, for example, one lower roller 4 is attached to the lower roller box 8. The side plates 6 a and 6 a of the slider body 6 are provided with a notch 10 through which the guide rail 1 is passed. An upper roller box 7 is attached above the notch 10, and a lower roller box 8 is attached below the notch 10. It has been. Each roller box 7, 8 is attached to the slider body 6 by a screw 11.

  Here, the hole 7a that penetrates the screw 11 provided in the side plate of the upper roller box 7 is a round hole corresponding to the thickness of the screw 11, whereas it is provided in the side plate of the lower roller box 8. The hole 8a through which the screw 11 passes is an elongated hole elongated in the vertical direction. Therefore, the mounting position of the upper roller box 7 cannot be adjusted, but the mounting position of the lower roller box 8 can be adjusted. That is, the screw 11 for attaching the lower roller box 8 is loosened, and the position of the lower roller box 8 can be shifted in the vertical direction until the screw 11 hits the upper and lower edges of the long hole 8a. By shifting the lower roller box 8 upward, the distance between the upper and lower rollers 4 becomes narrower, so that the force for sandwiching the guide rails 1 of the upper and lower rollers 4 increases, and the movement resistance force of the slider 2, that is, the slider 2 is moved. Increases the power required to On the other hand, since the distance between the upper and lower rollers 4 is increased by shifting the lower roller box 8 downward, the force for sandwiching the guide rail 1 between the upper and lower rollers 4 is reduced, and the movement resistance force of the slider 2 is reduced. That is, in this embodiment, the movement resistance adjusting means for increasing or decreasing the movement resistance force of the slider 2 is configured by the screw 11 and the long hole 8a.

  The center of each roller 4 is recessed, so that the guide rail 1 can be firmly sandwiched. Further, since an elliptical pipe is used as the guide rail 1, the slider 2 is not easily inclined in the circumferential direction of the guide rail 1 as compared with the round pipe. That is, in the present embodiment, an inclination preventing means that makes it difficult for the slider 2 to incline in the circumferential direction of the guide rail 1 is configured by making the cross-sectional shape of the guide rail 1 an elliptical shape. In the present embodiment, a stopper 43 that contacts the guide rail 1 when a large load in the circumferential direction of the guide rail 1 is applied to the slider 2 is attached to the inside of the slider body 6. For this reason, even if a large load in the circumferential direction of the guide rail 1 is applied to the slider 2, the inclination is limited, and interference between the fixture 5 and the slider 2 in the middle of the guide rail 1 can be more reliably prevented. Is done.

  A belt mounting shaft 12 is fixed to the lower portion of the slider body 6.

  The moving handrail 3 is, for example, a bar material, and metal fittings 13 are attached to both ends thereof. The lower end of the belt 14 is connected to the metal fitting 13. The upper end of the belt 14 is connected to the shaft 12 of the slider body 6. A length-adjusting metal fitting 15 is provided in the middle of the belt 14, and the belt 14 is loosened with respect to the metal fitting 15 that frictionally engages the folded belt 14 to increase or decrease the length of the folded portion of the belt 14. Thus, the length of the belt 14 can be adjusted. By adjusting the length of the belt 14, the height of the moving handrail 3 can be adjusted. That is, in the present embodiment, the length-adjustable belt 14 is the height adjusting means of the moving handrail 3.

  In this walking assist device, the movable handrail 3 is suspended on the slider 2 by using the deformable belt 14, so that even if the movable handrail 3 is pulled obliquely, the connecting portion of the belt 14 and the slider 2 and the movement of the belt 14 are moved. No extra burden is applied to the connection part of the handrail 3 and the durability is excellent. Moreover, since the belt 14 deform | transforms according to a pedestrian's attitude | position, it is easy for a pedestrian to take the attitude | position which suits himself. Furthermore, it becomes easy for pedestrians to leave their bodies on the handrail 3 and it is possible to prevent picking up. Moreover, a pedestrian can move between the wall and the moving handrail 3. That is, for example, when the pedestrian moves while looking at the wall to the left, the moving handrail 3 can be grasped with the right hand.

  This walking assist device is provided with a linear member 16 connected to the slider 2 and extending along the guide rail 1 and hanging from the vicinity of the end of the guide rail 1. The linear member 16 is, for example, a wire. However, it is not limited to a wire, and may be a string or a rope. The linear member 16 is bridged between pulleys 17 at both ends of the guide rail 1, and both ends thereof are connected to metal fittings 18 attached to both ends of the guide rail 1. Since the linear member 16 is longer than the guide rail 1, it hangs outward from the pulley 17 to form a loop. A weight 19 is provided on the hanging portion (loop portion) 16a. Specifically, the linear member 16 is passed through the ring portion 19a of the weight 19, and the weight 19 is hung from the lowest part of the loop by its own weight. When the weight 19 pulls the linear member 16 downward, the linear member 16 is tightly stretched between the two pulleys 17, and the linear member 16 can be prevented from being detached from the pulley 17.

  The center of the linear member 16 is connected to the arm 9 of the slider 2. For this reason, the linear member 16 also moves with the movement of the slider 2, and the size of the loop of the left and right hanging portions 16a changes. That is, in FIG. 1, when the slider 2 moves to the left side, the loop of the left hanging part 16a becomes large and the weight 19 is lowered, and the loop of the right hanging part 16a becomes small and the weight 19 is raised. On the contrary, when the slider 2 moves to the right side, the loop of the right hanging part 16a becomes large and the weight 19 is lowered, and the loop of the left hanging part 16a becomes small and the weight 19 is raised. Further, the slider 2 can be moved by the pedestrian pulling the linear member 16.

  Note that the movement resistance force of the slider 2 can be increased or decreased by changing the weight of the weight 19. That is, when the weight 19 is made heavy, the force necessary to move the slider 2 increases, and when the weight 19 is lightened, the force necessary to move the slider 2 decreases. For this reason, the movement resistance adjusting means for increasing or decreasing the movement resistance force of the slider 2 can be configured by exchanging the weight 19.

  The walking assistance device of the present invention is installed for the purpose of supplementing the fixed handrail facility 20 installed on the wall surface of a building, for example. For this reason, the guide rail 1 is provided in the place where the fixed handrail facility 20 is interrupted, and is provided above the position connecting the ends of the interrupted fixed handrail facility 20. The place where the fixed handrail facility 20 is interrupted includes a place where an entrance / exit is provided in the middle of the wall, a place where a passage intersects, and the like. However, the installation location of the walking assistance device is not limited to the location where the fixed handrail facility 20 is interrupted, and may be provided, for example, in the upper space on the side of the bed, the upper space in the center of the passage, or the like.

  Next, the use of the walking assist device will be described.

  A fixed handrail facility 20 is provided on a wall of a passage in the building, and a pedestrian such as a disabled person or an elderly person moves while holding the fixed handrail facility 20. A pedestrian who has moved to the interrupted end while grasping the fixed handrail facility 20 can move to the end of the fixed handrail facility 20 on the opposite side by moving while grasping the moving handrail 3 of the walking assist device. That is, the pedestrian can cross the place where the fixed handrail facility 20 is interrupted.

When the pedestrian moves while grasping the moving handrail 3, the roller 4 sandwiching the outer peripheral surface of the guide rail 1 rolls, and the slider 2 is guided by the guide rail 1 and moved. For this reason, the pedestrian can move while grasping the moving handrail 3 in the range where the guide rail 1 is provided. Since the roller 4 of the slider 2 sandwiches the outer peripheral surface of the guide rail 1,
Unlike the case where the slider 2 is accommodated in the guide rail 1, it is not necessary to provide a slit in the guide rail 1, and the rigidity of the guide rail 1 can be increased. For this reason, even if the force which inclines to the slider 2 acts, the guide rail 1 is not deformed.

  When the walking assist device is continuously used in the same movement direction, the slider 2 is initially moved to the other end of the guide rail 1 in the second use. In such a case, the pedestrian can pull the linear member 16 and pull the slider 2 from the far side. For example, in the state of FIG. 1, when a pedestrian moves from the left side to the right side of the walking assistance device, the hanging part 16a on the left side in FIG. When the left hanging portion 16a is pulled, the linear member 16 moves to the left side in the figure, and the slider 2 can be moved to the left side in the figure. Thus, even if the slider 2 is moving to the other side of the walking assist device, the pedestrian can pull the linear member 16 and pull the slider 2 toward this side. The walking assistance device can also be used when moving in the same direction. For this reason, it is suitable for use by a plurality of persons, and is particularly suitable for installation in facilities used by many people such as hospitals, nursing homes, and government offices.

  Further, a weight 19 is provided on the hanging portion 16a of the linear member 16 pulled by the pedestrian, and the weight 19 is suspended by passing the linear member 16 through the ring portion 19a. The linear member 16 can be moved by grasping and pulling. For this reason, compared with the case where the linear member 16 is directly grabbed and pulled, it is easy to operate and the usability can be improved. Further, by providing the weight 19, it is possible to reduce the force required for the pedestrian to pull the slider 2 around. Further, when the pedestrian pulls the weight 19, the linear member 16 forms a loop, so that the slider 2 can be moved by half the amount of movement of the slider 2.

  Since the walking assist device of the present invention is provided with the tilt preventing means, the length of the guide rail 1 can be increased. That is, if the guide rail 1 is short, it is sufficient to fix only both ends thereof to the upper wall surface 42 with the fixture 5. However, when the guide rail 1 is lengthened, it is necessary to fix the middle portion thereof to the upper wall surface 42 with the fixture 5. There is. When the slider 2 moves along the outer peripheral surface of the guide rail 1, if the slider 2 is inclined in the circumferential direction of the guide rail 1, there is a possibility of interfering with the fixture 5 on the way. By preventing the slider 2 from tilting in the circumferential direction of the guide rail 1 by the tilt preventing means, interference between the fixture 5 and the slider 2 in the middle of the guide rail 1 can be prevented. For this reason, the guide rail 1 can be lengthened and a long distance movement can be enabled while being held by the handrail 3 of the pedestrian.

  In addition, since the walking assist device of the present invention is provided with the movement resistance adjusting means, the force (movement resistance force) required to move the slider 2 can be increased or decreased. For this reason, the movement resistance force of the slider 2 can be adjusted according to the degree of pedestrian obstacle or body weakness. For this reason, usability improves. Further, for example, by increasing the movement resistance force of the slider 2, it is possible to apply an appropriate load to the pedestrian, so that exercise function recovery training can also be performed.

  Furthermore, since the walking assistance device of the present invention is provided with the height adjusting means of the moving handrail 3, the height of the moving handrail 3 can be adjusted according to the physique and physical condition of the pedestrian. For this reason, the usability of the walking assist device can be improved. For example, it is conceivable to adjust the height of the handrail 3 according to the height of the pedestrian. Also, is it better to be held on the moving handrail 3 so that the weight is placed on the moving handrail 3 so that the weight is applied from above, or is it better to be held on the moving handrail 3 so as to hang on the moving handrail 3? It is conceivable to adjust the height of the handrail 3 according to the above.

  Next, a second embodiment of the walking assistance device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. The walking assist device shown in FIG. 5 is provided with one slider 2 with a movable handrail 3 suspended on one side half 1a and one side half 1b of one guide rail 1, and two sliders. The connecting mechanism 21 is connected to the slider 2 so that the moving direction is reversed. The connecting mechanism 21 is pulled by the movement of one slider 2 and pulls the other slider 2 in the direction opposite to the moving direction. In FIG. 5, the slider 2 shown on the left side is called a left slider 2L, and the slider 2 shown on the right side is called a right slider 2R.

  The connection mechanism 21 includes, for example, four pulleys 22, 22, 23, and 23 and two connection wires 24 and 24. Of the four pulleys, two are pulleys having one groove (hereinafter referred to as a single groove pulley) 22 around which the connecting wire 24 is wound, and the remaining two are pulleys having two grooves around which the connecting wire 24 is wound. (Hereinafter referred to as “two-groove pulley”) 23. Each pulley 22, 22, 23, 23 is rotatably attached to a fixture 5 that fixes the guide rail 1 to the upper wall surface 42. More specifically, one single groove pulley 22 is provided for each fixture 5 that fixes both ends of the guide rail 1, and two two-groove pulleys 23 are provided for one fixture 5 that fixes the center of the guide rail 1. Are attached to each. Each pulley 22, 22, 23, 23 is attached so that the rotation axis is vertical.

  One end of the connecting wire 24 connected to the left end of the left slider 2L is a single groove pulley 22 arranged at the left end of the guide rail 1 → the upper groove of the two groove pulley 23 arranged at the center left side → the center right side. After being wound around the lower groove of the arranged two-groove pulley 23, the other end is connected to the left end of the right slider 2R. Further, the connecting wire 24 whose one end is connected to the right end of the right slider 2R is a single groove pulley 22 arranged at the right end of the guide rail 1 → the upper groove of the two groove pulley 23 arranged at the center right side → the center. After being wound around the lower groove of the two-groove pulley 23 arranged on the left side, the other end is connected to the right end of the left slider 2L.

  Therefore, for example, when the left slider 2L is moved from the left end of the guide rail 1 toward the center, the coupling mechanism 21 moves the right slider 2R from the right end of the guide rail 1 toward the center (operation indicated by arrow A in FIG. 5). ). When the left slider 2L is returned from the center of the guide rail 1 toward the left end, the coupling mechanism 21 moves the right slider 2R from the center of the guide rail 1 toward the right end (operation indicated by arrow B in FIG. 5). This movement is the same when moving the right slider 2R instead of moving the left slider 2L. That is, the two sliders 2 move toward each other toward the center of the guide rail 1 or away from each other toward both ends of the guide rail 1 by the action of the connecting mechanism 21.

  For example, when the pedestrian moves from the left end of the guide rail 1 toward the center while being held by the moving handrail 3 suspended on the left slider 2L (hereinafter referred to as the left moving handrail 3L), the pedestrian is suspended on the right slider 2R. A moving handrail 3 (hereinafter, referred to as a right handrail 3R) moves from the right end of the guide rail 1 toward the center. Then, the pedestrian moves from the left handrail 3L to the right handrail 3R at the center of the guide rail 1. Thereafter, the pedestrian moves toward the right end of the guide rail 1 while being held by the right handrail 3R. At the same time, the left moving handrail 3L and the left slider 2L are returned from the center of the guide rail 1 toward the left end by the connecting mechanism 21.

  Thus, the two moving handrails 3L and 3R are always returned to both ends of the guide rail 1 by the movement of the pedestrian. For this reason, in the standby state, the moving handrails 3 are always arranged at both ends of the guide rail 1, and the next person who uses the walking assistance device can use it as it is, regardless of which direction the moving direction is. It can be used continuously as it is.

  Next, a third embodiment of the walking assistance device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. The walking assist device shown in FIG. 6 includes a return means 25 that returns the slider 2 to a specific end of the guide rail 1. In the present embodiment, the return means 25 is to return the slider 2 to the lower end of the guide rail 1 by using the gravity by inclining the guide rail 1. In FIG. 6, the left end of the guide rail 1 is the lower end (specific end).

  Therefore, after the pedestrian moves from the left side to the right side of the walking assist device while grasping the moving handrail 3, when the hand is released from the moving handrail 3, the slider 2 naturally returns to the original position (lower left end) by gravity. . For this reason, the moving handrail 3 can be automatically returned to the same side after using the walking assist device. Further, since it is sufficient to incline the guide rail 1, no special mechanism is required as the return means 25, and an increase in manufacturing cost can be suppressed. Here, if the inclination angle of the guide rail 1 is increased, the movement resistance force of the slider 2 when used by a pedestrian increases. Further, when the inclination angle of the guide rail 1 is reduced, the return of the slider 2 becomes unstable. For this reason, the inclination angle of the guide rail 1 is appropriately determined in consideration of the body condition of the pedestrian to be used and the certainty of the return of the slider 2.

  In addition, the linear member 16 and the weight 19 are provided in the walking assistance device of FIG. 6, and the pedestrian moves from the higher end of the guide rail 1 to the lower end (in FIG. 6, the right side to the left side of the walking assistance device). When moving toward, the handrail 3 may be moved around.

  Next, a fourth embodiment of the walking assist device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. The walking assist device shown in FIG. 7 includes two sets 26 each having a guide rail 1, a slider 2, a moving handrail 3, and a return means 25, and one set 26 of the guide rails 1 is arranged with one end being low. The guide rails 1 of the other set 26 are arranged with the other end being low, and the guide rails 1 of each set 26 are arranged so as to be shifted in the radial direction when viewed from above. In the present embodiment, the guide rail 1 arranged on the lower side is fixed to the upper wall surface 42 with a short-length fixture 5, and the guide rail 1 arranged on the upper side is fixed to the upper wall surface 42 with a long-length fixture 5. Thus, the two guide rails 1 are shifted in the radial direction in a state viewed from above while changing the distance from the wall surface upper part 42. The guide rail 1 disposed on the lower side has a lower left end, and the guide rail 1 disposed on the upper side has a lower right end.

  In the standby state, the moving handrail 3 of the lower set 26 is moved to the left end of the guide rail 1, and the moving handrail 3 of the upper set 26 is moved to the right end of the guide rail 1. Now, when a pedestrian moves from the left side to the right side of the walking assist device, the pedestrian moves while grasping the moving handrail 3 of the lower set 26. When the pedestrian moves to the right end of the guide rail 1 and then releases the moving handrail 3, the slider 2 moves toward the left end of the guide rail 1 by gravity, and the moving handrail 3 can be naturally returned to the original position. . Similarly, when a pedestrian moves from the right end of the guide rail 1 toward the left end, the pedestrian moves while grasping the moving handrail 3 of the upper set 26. When the pedestrian moves to the left end of the guide rail 1 and then releases the moving handrail 3, the slider 2 moves toward the right end of the guide rail 1 by gravity, and the moving handrail 3 can be naturally returned to the original position. .

  Thus, the moving handrail 3 can be automatically returned to the original position after using the walking assistance device. For this reason, the person (pedestrian) who uses the walking assistance device next can use it as it is, and can use it continuously as it is regardless of the direction of movement.

  Next, a fifth embodiment of the walking assist device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. In the walking assistance device shown in FIG. 8, two sliders 2 on which the handrail 3 is suspended are provided on one guide rail 1, and two return means 25 are provided. The slider 2 provided on one end side is returned to one end of the guide rail 1, and the slider 2 provided on the other end side of the guide rail 1 is returned to the other end of the guide rail 1 by the other return means 25. .

  The return means 25 includes an elastic member that is elastically deformed in accordance with the movement of the slider 2. The elastic member is, for example, a mainspring. The elastic member is connected to, for example, a roller (not shown) for winding the wire 30 and is accommodated in the case 31 together with this roller. When the wire 30 is pulled out from the case 31, the roller that has wound the wire 30 rotates and the elastic member is elastically deformed. For this reason, the elastic force which reverses a roller generate | occur | produces. And if the force which pulls out the wire 30 from the case 31 reduces, a roller will reversely and will wind up the wire 30. FIG.

  In FIG. 8, the return means 25 for returning the slider 2 provided on the left side (hereinafter referred to as the left slider 2L) to the left end of the guide rail 1 is fixed to the left end of the guide rail 1, and the tip of the wire 30 is the left slider. It is connected to the left end of 2L. The return means 25 for returning the slider 2 provided on the right side (hereinafter referred to as the right slider 2R) to the right end of the guide rail 1 is fixed to the right end of the guide rail 1, and the tip of the wire 30 is connected to the right slider 2R. It is connected to the right end.

  Therefore, in the standby state, the left slider 2L is pulled toward the left end of the guide rail 1, and the right slider 2R is pulled toward the right end of the guide rail 1. Consider a case where a pedestrian moves from the left side to the right side of the walking assist device. In this case, the left handrail 3 suspended from the left slider 2L is used. When a pedestrian moves in the direction from the left end of the guide rail 1 toward the opposite right end while grasping the left handrail 3, the wire 30 of the left return means 25 is pulled out from the case 31 and the elastic member is deformed. The elastic force to wind up 30 is stored.

  After the pedestrian moves to the right end of the guide rail 1, when the pedestrian releases his hand from the moving handrail 3, the elastic force stored in the elastic member reverses the roller and winds the wire 30. Thereby, the left slider 2L is pulled back from the right end of the guide rail 1 to the left end.

  Similarly, when the pedestrian moves from the right side to the left side of the walking assist device, the right handrail 3 suspended from the right slider 2R is used. By this movement, the wire 30 of the right return means 25 is pulled out from the case 31, and an elastic force for winding the wire 30 is stored. After the pedestrian moves to the left end of the guide rail 1, when the pedestrian releases his hand from the moving handrail 3, the wire 30 is wound up and the right slider 2R is returned from the left end of the guide rail 1 to the right end.

  In this way, the handrail 3 can be automatically returned to the same side after using the walking assistance device. Therefore, the next person who uses the walking assistance device can use it as it is, and can use it continuously as it is regardless of the direction of movement. In addition, since an elastic member is used as the return means 25, a driving source such as a motor is unnecessary. For this reason, a walking assistance apparatus can be installed in a place without a power supply, or a battery and battery replacement can be made unnecessary.

  Note that a brake mechanism that prevents the wire 30 from being taken up rapidly may be provided in the return means 25. By providing the brake mechanism, it is possible to prevent the wire 30 from being abruptly wound and the slider 2 to be returned vigorously.

  Next, a sixth embodiment of the walking assistance device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. The walking assist device shown in FIG. 9 does not include any of the linear member 16 that is a means for pulling the slider 2 and the return means 25 that returns the slider 2 to a specific end. That is, it is a type of walking assist device that cannot return the slider 2 moved to the opposite side to the original position without the movement of the pedestrian and does not consider using it continuously in the same direction. The walking assist device is installed, for example, in a place where an entrance is provided. When the walking assistance device is used alone by installing it in a private house, it is considered that the walking assistance device will not be used continuously in the same direction. 16 and the return means 25 for returning the slider 2 to a specific end can be omitted. In this case, the manufacturing cost of the walking assistance device can be reduced, and the walking assistance device can be provided at low cost.

  Next, a seventh embodiment of the walking assistance device of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member same as the above-mentioned member, and detailed description is abbreviate | omitted. The walking assistance device shown in FIG. 10 is installed at a place where the passages intersect. Since there is no wall up to the ceiling at the place where the passages intersect, the guide rail 1 is fixed to the ceiling 44. Each fixture 5 is fixed at a position where a strength member 46 such as a beam or a beam of the ceiling 44 is provided. When fixing the guide rail 1 to the ceiling 44, the guide rail 1 can be arranged at a desired height by adjusting the length of the fixture 5.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention.

  For example, although the above-described walking assistance device includes the movement resistance adjusting means, the movement resistance adjusting means may be omitted.

  Moreover, although the above-mentioned walking assistance apparatus was provided with the height adjustment means, you may abbreviate | omit a height adjustment means.

  In the above description, the belt 14 is used to suspend the movable handrail 3. However, a rod-shaped member may be used instead of the belt 14. An eighth embodiment using the rod-shaped member 32 is shown in FIG.

  In the above description, the height adjusting means for adjusting the height of the moving handrail 3 is configured by the belt 14 that can be adjusted in length. However, the height adjusting means is not necessarily limited to this configuration. For example, the belt 14 may be connected to the slider 2 and the moving handrail 3 by a one-touch detachable joint, and the height of the moving handrail 3 may be adjusted by replacing the belt 14 with a different length. Further, when the rod-shaped member 32 is used in place of the belt 14, for example, as shown in FIGS. 11 and 12, the height adjusting mechanism 33 of the rod-shaped member 32 constitutes the height adjusting means of the moving handrail 3. Also good. Furthermore, a means for adjusting the height of the moving handrail 3 by providing moving handrail attachment joints at a plurality of positions where the height of the belt 14 or the rod-shaped member 32 is different and replacing the moving handrail 3 at different height positions may be used. .

  11 and 12, for example, the rod-like member 32 is divided into an outer cylinder 32a and an inner cylinder 32b, and a convex portion 34 provided so as to be able to protrude and retract in the inner cylinder 32b is provided in the hole 35 of the outer cylinder 32a. By inserting the outer cylinder 32a, the outer cylinder 32a and the inner cylinder 32b are integrated, and the length as the rod-shaped member 32 is fixed. The outer cylinder 32a is provided with a plurality of holes 35, and the length of the rod-shaped member 32 can be changed by changing the hole 35 into which the convex portion 34 is inserted. A spring 36 is provided at the back of the convex portion 34, and the convex portion 34 can be pushed in while the spring 36 is compressed. Then, after adjusting the length by moving the outer cylinder 32 a relative to the inner cylinder 32 b, when the convex portion 34 faces the hole 35, the convex portion 34 is inserted into the hole 35 by the spring 36. A moving handrail 3 is provided at the lower end of the inner cylinder 32 b, and the upper end of the outer cylinder 32 a is swingably connected to the slider 2 by a shaft 45.

  In the above description, the movement resistance adjusting means is configured by the screw 11 and the long hole 8a. However, the movement resistance adjusting means is not necessarily limited to this configuration. For example, the roller 4 may be pressed against the guide rail 1 by the elastic force of a spring, and the elastic force of the spring may be increased or decreased to serve as a movement resistance adjusting means. Further, when the weight of the weight 19 changes, the force necessary to move the slider 2 also changes. Therefore, increasing or decreasing the weight of the weight 19 may be used as the movement resistance adjusting means. Further, when the guide rail 1 is tilted and its angle is changed, the force required to move the slider 2 also changes. Therefore, changing the tilt angle of the guide rail 1 may be used as the movement resistance adjusting means.

  FIG. 13 shows means for adjusting the movement resistance by pressing the roller 4 against the guide rail 1 by the elastic force of the spring and increasing or decreasing the elastic force of the spring. An elastic body (for example, a leaf spring) 37 is disposed between the lower roller box 8 and the slider body 6, and the lower roller box 8 is disposed on the slider body 6 while pressing the elastic body 37. At this time, an elastic force is stored in the pushed-in elastic body 37, and the guide rail 1 is sandwiched by the elastic force. By turning the adjusting screw 38 and moving the fulcrum of the elastic body 37 up and down, the elastic force can be increased or decreased.

  Further, when the movement resistance adjusting means is configured by increasing / decreasing the elastic force of the elastic body 37, a drive mechanism 36 for moving the elastic body 37 up and down may be provided. An example of the drive mechanism 36 is shown in FIGS. The drive mechanism 36 includes, for example, a cam 39 that pushes up the elastic body 37, a knob 40 that rotates the cam 39, and a shaft 42 that connects the knob 40 and the cam 39.

  When the knob 42 is operated to rotate the shaft 42, the cam 39 also rotates, and the base plate 37 a moves up and down according to the radius of the portion that contacts the base plate 37 a that supports the elastic body 37. That is, the fulcrum of the elastic body 37 connected to the base plate 37a moves up and down. A mark 40a is formed on the knob 40, and a guide display 41 is attached to the slider 2 corresponding to the mark 40a. As the guidance display 41, for example, characters “strong”, “medium”, and “weak” indicating the magnitude of the movement resistance force of the slider 2 are attached. When the mark 40a is set to “strong”, the maximum radius portion of the cam 39 contacts the base plate 37a. For this reason, the bending of the elastic body 37 is increased, the elastic force is increased, the force for sandwiching the guide rail 1 is increased, and the movement resistance force of the slider 2 is “strong”. Further, when the mark 40a is set to “medium”, the portion with the second largest radius of the cam 39 comes into contact with the base plate 37a. For this reason, the bending of the elastic body 37 is the second largest, the elastic force is also the second largest, the force sandwiching the guide rail 1 is the second largest, and the movement resistance force of the slider 2 is set to “medium”. On the other hand, when the mark 40a is set to “weak”, the minimum radius portion of the cam 39 contacts the base plate 37a. For this reason, the bending force and elastic force of the elastic body 37 are minimized, the force for sandwiching the guide rail 1 is reduced, and the movement resistance force of the slider 2 is “weak”.

  The movement resistance adjusting means provided with the drive mechanism 36 is very convenient because the movement resistance force can be easily adjusted by operating the knob 40. Further, since the mark 40a and the guide display 41 are provided, the movement resistance can be easily adjusted and the usability is very good.

  In the above description, the notch 10 is formed in the slider body 6 of the slider 2 so as not to surround the entire circumference of the guide rail 1 so as to avoid interference with the mounting tool 5 in the middle. When the guide rail 1 is short and it is not necessary to place the fixture 5 in the middle of the guide rail 1, the slider 2 surrounds the entire circumference of the guide rail 1 as shown in FIG. It may be.

  In the above description, the tilt preventing means is configured by making the cross-sectional shape of the guide rail 1 elliptical. However, the tilt is prevented by making the cross-sectional shape of the guide rail 1 a shape other than the elliptical shape. Means may be configured. That is, the inclination preventing means may be configured by making the cross-sectional shape of the guide rail 1 other than a circular shape. For example, as shown in FIG. 11, the inclination preventing means may be configured by making the cross-sectional shape of the guide rail 1 hexagonal. Further, the slider 2 may be prevented from being inclined by providing a groove along the longitudinal direction on the outer peripheral surface of the guide rail 1 and inserting a guide or the like formed on the slider 2 into the groove. In the inclination preventing means having such a configuration, the cross-sectional shape of the guide rail 1 can be made circular.

  Further, the guide rail 1 may be curved. By curving the guide rail 1, it is possible to cope with a curve such as a passage. That is, the use of the walking assist device is not limited to the case of performing a straight line movement, but can also be used for the case of a curved line movement.

  The walking assistance device of the present invention may be used for purposes other than the purpose of supplementing the fixed handrail facility 20. For example, since the movement resistance force of the slider 2 can be adjusted by the movement resistance adjusting means, it may be used for the purpose of performing exercise function recovery training.

  Furthermore, a walking assistance device may be used to get up from the bed. For example, the guide rail 1 is fixed to the ceiling 44 or the upper wall 42 on the side of the bed in parallel with the bed, and the moving handrail 3 is suspended at a position that can be reached by a person sleeping on the bed. When a person who is sleeping on the bed gets up, he gets out of his hand, grasps the moving handrail 3, and gets up while pulling the moving handrail 3 in a direction perpendicular to the longitudinal direction of the guide rail 1. By pulling the moving handrail 3 in a direction perpendicular to the longitudinal direction of the guide rail 1, the slider 2 does not move. And after waking up, it can move along the guide rail 1 while holding the moving handrail 3 as it is.
