The configuration of the handrail 40 will be described with reference to FIGS.
As shown in FIG. 2, the handrail 40 includes a first handrail 50, a second handrail 60, and an intermediate handrail 70. The handrail 40 is connected in the order of the first handrail 50, the intermediate handrail 70, and the second handrail 60 from the heel S side to the soil G side, and constitutes one handrail 40.

  The first handrail 50 has a bar shape extending in the horizontal direction. As shown in FIG. 3, the cross-sectional shape of the first handrail 50 has a flat shape. The size in the width direction of the cross section of the first handrail 50 is larger than the size in the height direction. As shown in FIG. 2, the first handrail 50 is curved so that the end portion 51 on the side of the heel S is bent downward and is further wound inside the longitudinal direction of the handrail 40. The support surface 53, which is the surface of the first handrail 50 that supports the palm, is coated with elastomer resin on the surface, and the end portion 51 is not coated with elastomer resin. Thereby, the friction coefficient of the support surface 53 is set larger than the friction coefficient of the end portion 51. A slide groove 52 is formed on the lower surface of the first handrail 50.

  The second handrail 60 has a bar shape extending in the horizontal direction. The cross section of the second handrail 60 has a flat shape similar to the cross section of the first handrail 50 shown in FIG. The size in the width direction of the cross section of the second handrail 60 is larger than the size in the height direction. As shown in FIG. 2, the second handrail 60 is curved so that the end 61 on the side of the soil G bends downward and is further wound inside the handrail 40 in the longitudinal direction. The support surface 63 that is the surface of the second handrail 60 that supports the palm is coated with an elastomer resin on the surface, and the end portion 61 is not coated with the elastomer resin. Thereby, the friction coefficient of the support surface 63 is set larger than the friction coefficient of the end portion 61. A slide groove 62 is formed on the lower surface of the second handrail 60.

  The intermediate handrail 70 has a linear bar shape. As shown in FIG. 4, the cross-sectional shape of the intermediate handrail 70 has a perfect circular shape. The maximum diameter of the cross section of the intermediate handrail 70 is smaller than the size in the width direction of the first handrail 50 and the second handrail 60. An elastomer resin is applied to the outer peripheral surface 71 of the intermediate handrail 70.

  As shown in FIG. 5, the first handrail 50 and the intermediate handrail 70 are connected via a hinge 72. Specifically, a part of the hinge 72 that is rotatably fixed to the intermediate handrail 70 is inserted into an open portion on the intermediate handrail 70 side of the slide groove 52, and the intermediate handrail 70 and a bolt (illustrated). Abbreviated). In this way, the intermediate handrail 70 is rotatably connected to the first handrail 50.

  As shown in FIG. 2, the second handrail 60 and the intermediate handrail 70 are connected via a hinge 73 by the same connection structure as the first handrail 50 and the intermediate handrail 70. A part of the hinge 73 that is rotatably fixed to the intermediate handrail 70 is inserted into an opening portion of the slide groove 62 on the intermediate handrail 70 side, and is fixed by the intermediate handrail 70 and a bolt (not shown). The In this way, the intermediate handrail 70 is rotatably connected to the second handrail 60.

With reference to FIG. 2 and FIG. 5, the slide structure of the 1st handrail 50 and the 2nd handrail 60 and the support part 30 is demonstrated.
As shown in FIG. 5, a slide portion 31D is fixed to the upper end portion of the first top portion 31C. The slide portion 31D is fitted in the slide groove 52. For this reason, the first handrail 50 can slide in the longitudinal direction of the first handrail 50 with respect to the first top portion 31C. When the auxiliary instrument 10 is used, the first top portion 31C is fixed to the first handrail 50 by the bolt B.

  As shown in FIG. 2, a slide portion 32D is fixed to the upper end portion of the second top portion 32C. The slide portion 32D is fitted in the slide groove 62 in the same manner as the slide portion 31D of the first top portion 31C shown in FIG. For this reason, the second handrail 60 can slide in the longitudinal direction of the second handrail 60 with respect to the second top portion 32C. When the auxiliary instrument 10 is used, the second top portion 32C is fixed to the second handrail 60 with a bolt (not shown).

The height adjustment function of the handrail 40 of the assembly C will be described with reference to FIG.
When changing at least one of the upper stage height HX1 that is the height from the heel S of the first handrail 50 and the lower stage height HX2 that is the height from the base 20 of the second handrail 60, the hinge 72, 73 and the slide structure function.

  For example, when the height of the handrail 40 shown by the solid line in FIG. 6 is changed to the height of the handrail 40 shown by the two-dot chain line in FIG. 6, the slide portion 31D slides in the slide groove 52, and in the horizontal direction. The first handrail 50 moves inward in the longitudinal direction of the handrail 40. Further, the slide portion 32D slides in the slide groove 62, and the second handrail 60 moves inward in the longitudinal direction of the handrail 40 in the horizontal direction. Further, the intermediate handrail 70 rotates with respect to the first handrail 50 and the second handrail 60, and the posture of the intermediate handrail 70 changes so that the inclination angle becomes small. Thereby, the height of the 1st handrail 50 and the 2nd handrail 60 can be changed maintaining the state where the longitudinal direction of the 1st handrail 50 and the 2nd handrail 60 followed the horizontal direction.

  For example, when the height of the handrail 40 shown by the two-dot chain line in FIG. 6 is changed to the height of the handrail 40 shown by the solid line in FIG. 6, the slide portion 31D slides in the slide groove 52, and in the horizontal direction. The first handrail 50 moves to the outside of the handrail 40 in the longitudinal direction. In addition, the slide portion 32D slides in the slide groove 62, and the second handrail 60 moves outward in the longitudinal direction of the handrail 40 in the horizontal direction. Further, the intermediate handrail 70 rotates with respect to the first handrail 50 and the second handrail 60, and the posture of the intermediate handrail 70 changes so that the inclination angle becomes small. Thereby, the height of the 1st handrail 50 and the 2nd handrail 60 can be changed maintaining the state where the longitudinal direction of the 1st handrail 50 and the 2nd handrail 60 followed the horizontal direction.

  In addition, the handrail 40 shown by the dashed-two dotted line of FIG. 6 and the handrail 40 shown by the continuous line of FIG. 6 are changing the height of both the 1st handrail 50 and the 2nd handrail 60. FIG. Since the height of the first handrail 50 and the second handrail 60 can be changed independently, the first handrail 50 and the second handrail 60 are maintained in the state where the height of one of the first handrail 50 and the second handrail 60 is maintained. Only the other height of the handrail 50 and the second handrail 60 can be changed.

  With reference to FIGS. 7-12, the effect | action of the auxiliary tool 10 is demonstrated. 7 to 10 show a comparative auxiliary instrument 100 of a comparative example, and FIGS. 11 and 12 show the auxiliary instrument 10. 7 to 12 illustrate users having the same physique. Further, the steps HS which are the heights of the ridges S in FIGS. 7, 8 and 11 are equal to each other. 9, 10, and 12 are equal to each other, and are lower than the steps HS in FIGS. 7, 8, and 11. 9, 10, and 12 do not have the intermediate base 21 attached to the foundation 20 because the step HS is low. In addition, the auxiliary | assistant instrument 10 of FIG. 9 and FIG.

  As shown in FIG. 7, the comparative assisting device 100 includes a handrail 140 formed integrally, and a first support column 131 and a second support column 132 that support the handrail 140. The handrail 140 includes a first handrail 150 that is a portion of the handrail 140 on the heel S side, and a second handrail 160 that is a portion on the side of the soil G.

  The handrail 140 can be translated in the vertical direction. For this reason, the height of the handrail 140 can be changed according to the user's physique and the like. However, since the handrail 140 is integrally formed, the handrail level difference HA, which is the relative height between the first handrail 150 and the second handrail 160, cannot be changed. Therefore, one of the upper height HX1 and the lower height HX2 is appropriate for the user depending on the user's physique, and the other of the upper height HX1 and the lower height HX2 is the physique of the user. A state with an inappropriate height that does not fit may be formed. For this reason, there exists a possibility that a user's operation | movement may become unstable. The inappropriate height includes, for example, a height at which the user's hand does not reach the handrails 150 and 160, a height at which the hand is difficult to place on the handrails 150 and 160, and the like.

  Specifically, as shown in FIGS. 7 and 8, when the step HS, which is the step of the heel S, is larger than the handrail step HA, the upper step height HX1 becomes smaller than the lower step height HX2. For this reason, as shown by the solid line in FIG. 7, when the upper stage height HX1 is set to a height that matches the user's physique, the lower stage height HX2 may be excessively higher than the user's physique. For this reason, for example, when ascending the heel S, the elbow of the user who placed his hand on the second handrail 160 is compared with the appropriate lower height HX2 indicated by the two-dot chain line in FIG. It becomes difficult to put weight on the second handrail 160 due to an increase in bending or a warping of the upper body. For this reason, a user's posture tends to become unstable.

  In addition, when the lower height HX2 is set to the height of the user's physique as shown by the solid line in FIG. 8, the upper height HX1 may be excessively lower than the user's physique. For this reason, for example, when climbing the heel S, the waist of the user who put his hand on the first handrail 150 is higher than the appropriate upper height HX1 indicated by the two-dot chain line in FIG. It becomes difficult to put weight on the first handrail 150 due to bending or an increase in bending. For this reason, a user's posture tends to become unstable.

  As shown in FIGS. 9 and 10, when the step HS, which is the step of the heel S, is smaller than the handrail step HA, the upper step height HX1 becomes larger than the lower step height HX2. For this reason, as shown by the solid line in FIG. 9, when the upper stage height HX1 is set to a height that matches the user's physique, the lower stage height HX2 may be excessively lower than the user's physique. Therefore, for example, when climbing the heel S, the waist of the user who placed his hand on the second handrail 160 is bent as compared with the case of the appropriate lower height HX2 indicated by the two-dot chain line in FIG. It becomes difficult to put weight on the second handrail 160 due to, for example, an increase in bending. For this reason, a user's posture tends to become unstable.

  Further, as shown by the solid line in FIG. 10, when the lower height HX2 is set to a height that matches the user's physique, the upper height HX1 may be excessively higher than the user's physique. For this reason, for example, when climbing the heel S, the upper body of the user who placed his hand on the first handrail 150 is warped as compared with the appropriate upper stage height HX1 indicated by the two-dot chain line in FIG. Or it becomes difficult to put weight on the 1st handrail 150, for example, the elbow bend becomes large. For this reason, a user's posture tends to become unstable.

  As described above, the comparative auxiliary instrument 100 can translate the handrail 140 in the vertical direction by changing the heights of the first support column 131 and the second support column 132. However, when the height of one of the first handrail 150 and the second handrail 160 is changed to an appropriate position for the user, the other height of the first handrail 150 and the second handrail 160 is set to the user. There is a risk of inappropriate height.

  On the other hand, as FIG. 11 and FIG. 12 show, the auxiliary | assistant instrument 10 can change the upper stage height HX1 and the lower stage height HX2 independently. For this reason, both upper stage height HX1 and lower stage height HX2 can be adjusted to a suitable height for a user.

  Specifically, when the upper stage height HX1 and the lower stage height HX2 are different as shown by the two-dot chain line in FIG. 11, the lower stage height is shown as shown by the solid line in FIG. Only the upper height HX1 is changed while maintaining HX2. Thereby, upper stage height HX1 and lower stage height HX2 can be made to correspond, and upper stage height HX1 can be changed into a suitable height for a user. As described above, the auxiliary device 10 can adjust both the upper height HX1 and the lower height HX2 to an appropriate height according to the physique of the user. For this reason, a user's operation | movement can be stabilized.

  Also, as shown in FIG. 12, when the step HS, which is the step of the heel S, is smaller than the handrail step HA, as shown by the two-dot chain line in FIG. 12, the upper step height HX1 and the lower step height HX2 When a state different from is formed, only the upper height HX1 is changed while maintaining the lower height HX2 as shown by the solid line in FIG. Thereby, upper stage height HX1 and lower stage height HX2 can be made to correspond, and upper stage height HX1 can be changed into a suitable height for a user. Thus, both the upper stage height HX1 and the lower stage height HX2 can be adjusted to an appropriate height according to the height of the ridge S.

The operation of the handrail 40 will be described with reference to FIG.
In the auxiliary device 10, the first handrail 50 is parallel to the upper surface of the heel S, which is a high step portion, the second handrail 60 is parallel to the soil gap G, which is a low step portion, and the intermediate handrail 70 has a step. In addition, it is arranged over the ridge S and the soil G.

When the user moves from the soil gap G to the heel S, the user places his palm on the support surface 63 of the first second handrail 60 and moves the body toward a position with a high step, which is the front, with the palm as a fulcrum.
The second handrail 60 has a flat cross-sectional shape, and a support surface 63 is formed. For this reason, it is suitable for supporting the palm. For this reason, when the user places the palm on the second handrail 60, a wide range of the palm is firmly supported by the support surface 63. For this reason, when the user moves the body forward with the palm as a fulcrum, the operation of the user is unlikely to become unstable.

  When the user moves from the soil G to the heel S across the steps, the position of the center of gravity of the body changes greatly, so that the user's operation tends to be more unstable than when moving on a plane. For this reason, many users hold the intermediate handrail 70 strongly when stepping over a step.

  The handrail 70 in the middle of the auxiliary device 10 has a circular shape in cross section. Further, the maximum diameter of the cross section of the intermediate handrail 70 is smaller than the size in the width direction of the cross sections of the first handrail 50 and the second handrail 60. For this reason, it is easier to grip than the first handrail 50 and the second handrail 60. For this reason, the intermediate handrail 70 can be firmly held when the user crosses the step. For this reason, a possibility that a user's operation | movement will become unstable when stepping over a level | step difference is reduced.

  When the user moves across the step to the heel S, the user places his palm on the first handrail 50 and moves the body toward the end 51 of the first handrail 50 which is the front using the palm as a fulcrum. Since the first handrail 50 of the auxiliary device 10 has a shape suitable for supporting the palm, when the user places the palm on the first handrail 50, a wide range of the palm is more firmly attached to the support surface 53. Is supported. For this reason, when the user moves the body forward with the palm as a fulcrum, the operation of the user is unlikely to become unstable.

  In addition, although the effect obtained by the auxiliary instrument 10 is shown here as an example in the case where the user moves from the soil G to the heel S, the above also applies to the case where the user moves from the heel S to the soil G. Similar effects can be obtained.

The auxiliary device 10 has the following effects.
(1) When the assembly C is installed on the foundation 20, the auxiliary device 10 adjusts the height of the first handrail 50 and the height of the second handrail 60 according to the physique of the user. it can. For this reason, there exists a possibility that the auxiliary | assistant instrument 10 may be used, while the height of one of the 1st handrail 50 and the 2nd handrail 60 does not match a user's physique and environment (for example, level | step difference HS of the heel S). Lower. For this reason, it can contribute to stabilizing a user's operation | movement.

  (2) When the user uses the auxiliary device 10, the auxiliary device 10 touches one handrail 40 constituted by the first handrail 50, the second handrail 60, and the intermediate handrail 70, The auxiliary device 10 can move from one end to the other end. For this reason, for example, compared with the case where the 1st handrail 50 and the 2nd handrail 60 have a discontinuous relationship, it can contribute further to stabilizing a user's operation.

  (3) The auxiliary device 10 has a structure in which the first handrail 50 slides with respect to the support portion 30 and a structure in which the posture of the intermediate handrail 70 with respect to the first handrail 50 and the second handrail 60 changes. Due to the action, the height of the first handrail 50 changes independently from the height of the second handrail 60. Note that the height of the second handrail 60 also changes independently from the height of the first handrail 50 by the same operation as described above.

  Moreover, since the 1st handrail 50 and the 2nd handrail 60 slide with respect to the support part 30, the support part 30, the handrail 40, and the foundation 20 are attached, and the adjustment leg 31B has been arrange | positioned on the heel S The height of the first handrail 50 and the second handrail 60 can be changed. For this reason, compared with the structure which removes each component of the auxiliary instrument 10, and changes the height of the 1st handrail 50 and the 2nd handrail 60, the height of the 1st handrail 50 and the 2nd handrail 60 Can be easily adjusted.

  (4) The auxiliary instrument 10 changes the height of the first handrail 50 when the length of the first support 31 changes, and changes the length of the second support 32 when the length of the second support 32 changes. The height changes. As described above, since the correspondence between the handrails 50 and 60 and the operation part for changing the height is clearly distinguished, the user intuitively adjusts the height of the handrail. It can be carried out.

  (5) The auxiliary instrument 10 has a plate-shaped foundation 20. Moreover, the lower end of the adjustment leg 31B is arrange | positioned on the collar S, and is not fixed to the collar S. For this reason, by attaching the auxiliary tool 10, it is suppressed that the earth G and the ridge S deform | transform. Moreover, the installation place of the auxiliary instrument 10 can be easily changed compared with the structure fixed to the earth | gap G and the fence S with a volt | bolt etc.

  (6) The 1st handrail 50, the 2nd handrail 60, and the intermediate handrail 70 which were formed separately are mutually connected, and the one handrail 40 is comprised. According to this configuration, at least one of the handrails 50, 60, 70 is used for the user's physique, the feeling that the user feels, or the scene in which the auxiliary device 10 is used, and the environment (for example, 框 S Can be adjusted according to the level difference HS). For this reason, the versatility of the auxiliary instrument 10 is improved.

  The specific form that the auxiliary device can take is not limited to the form exemplified in the above embodiment. The auxiliary device can take various forms different from the above-described embodiments as long as the object of the present invention is achieved. The modification of the said embodiment shown below is an example of the various forms which this auxiliary device can take.

  Both the slide structure of the first top portion 31C and the first handrail 50 and the slide structure of the second top portion 32C and the second handrail 60 can be omitted. In this case, instead of the slide structure, for example, the following configurations (A) to (D) may be employed for the auxiliary instrument 10.

(A) The intermediate handrail 70 is omitted. In this case, the handrail 40 is configured discontinuously.
(B) The first top portion 31C is structured to be fixed at a plurality of positions in the longitudinal direction of the first handrail 50. Further, the second top portion 32 </ b> C is structured to be fixed at a plurality of positions in the longitudinal direction of the second handrail 60. When changing the height of the first handrail 50, after removing the first handrail 50 and the first top portion 31C and moving the first handrail 50 to the inside or outside of the handrail 40 in the longitudinal direction, The top 31C is fixed at an appropriate position of the first handrail 50. Further, when changing the height of the second handrail 60, after removing the second handrail 60 and the second top 32C and moving the second handrail 60 to the inside or outside in the longitudinal direction of the handrail 40, The second top portion 32 </ b> C is fixed to an appropriate position of the second handrail 60.

  (C) The length of the handrail 40 can be changed. For example, as shown in FIG. 13, an intermediate handrail 170 having an expansion / contraction mechanism is employed. The two-dot chain line in FIG. 13 shows the shape of the handrail 40 when the height of the first handrail 50 is changed from the state shown by the solid line in FIG. 13 while maintaining the height of the second handrail 60. ing. The intermediate handrail 170 has a cylindrical first portion 170A and a rod-shaped second portion 170B. The first portion 170 </ b> A is connected to the first handrail 50 via the hinge 72. The second portion 170 </ b> B is connected to the second handrail 60 through the hinge 73. The end of the second portion 170B on the first handrail 50 side is housed inside the first portion 170A. In the intermediate handrail 170, as the difference between the height of the first handrail 50 and the height of the second handrail 60 increases, the second portion 170B protrudes from the first portion 170A, and the intermediate handrail 170 becomes longer.

  (D) The length of the handrail 40 of the support portion 30 in the longitudinal direction can be changed. For example, as shown in FIG. 14, a lower beam 134 and an upper beam 135 having an extension / contraction mechanism are employed. The two-dot chain line in FIG. 14 shows the shape of the handrail 40 when the height of the first handrail 50 is changed from the state shown in the solid line in FIG. 14 while maintaining the height of the second handrail 60. ing. The lower rail 134 has a cylindrical first portion 134A and a rod-shaped second portion 134B. The first portion 134 </ b> A is fixed to the first support column 31. The second portion 134B is connected to the second support column 132. The end of the second portion 134B on the first handrail 50 side is housed inside the first portion 134A. The upper rail 135 has a cylindrical first portion 135A and a rod-shaped second portion 135B. The first portion 135A is fixed to the first support column 31. The second portion 134B is connected to the second support column 132. The end of the second portion 135B on the first handrail 50 side is housed inside the first portion 135A. As the difference between the height of the first handrail 50 and the height of the second handrail 60 increases, the lower part 134 and the upper part 135 protrude from the first parts 134A and 135A, and the lower part 134 And the upper cross 135 becomes long. In accordance with this, the position of the first support column 31 on the heel S and the position of at least one of the second support column 32 on the foundation 20 are changed.

  -The 1st top part 31C and the 1st handrail 50 can be fixed, and a slide structure can also be abbreviate | omitted. Alternatively, the second top portion 32C and the second handrail 60 can be fixed and the slide structure can be omitted. Also in this case, the function of one of the slide structures enables the height of the first handrail 50 and the height of the second handrail 60 to be changed independently.

  -The handrail 40 can also be integrated. In this case, for example, it can be changed to the auxiliary instrument 200 shown in FIG. The two-dot chain line in FIG. 15 indicates the posture of the handrail 240 when the height of the handrail 240 on the heel S side is increased from the posture of the handrail 240 shown in the solid line in FIG. Is shown.

  The auxiliary instrument 200 includes a foundation 220 installed in the soil gap G, a support part 230 supported by the foundation 220, and a handrail 240 supported by the support part so as to be inclined with respect to the support part 230.

The support unit 230 includes a first support column 31 and a second support column 32. The first support column 31 and the second support column 32 support different portions of the handrail 240 in the longitudinal direction.
The first support portion 231D, which is a connection portion between the handrail 240 and the first support column 31, is configured so that the handrail 240 and the first support column 31 can rotate relatively. As shown in FIG. 16, the second support portion 232D, which is a connection portion between the handrail 240 and the second support column 32, has a rotation shaft 232E extending in the width direction of the handrail 240 at the top of the second support portion 232D. . The rotating shaft 232E is fitted in a slide groove 241 formed on the end surface of the handrail 240 in the width direction. Thereby, the handrail 240 can rotate with respect to 2nd support part 232D because the rotating shaft 232E rotates in the inside of the slide groove | channel 241. FIG. Further, the second shaft 32 can slide with respect to the longitudinal direction of the handrail 240 by the rotation shaft 232 </ b> E moving in the slide groove 241.

  In the auxiliary device 10, the posture of the handrail 240 with respect to the soil G changes according to the relationship between the height of the first support portion 231 </ b> D with respect to the soil gap G and the height of the second support portion 232 </ b> D. When the height of the first support portion 231D and the height of the second support portion 232D are set to the same height, the handrail takes a posture substantially parallel to the soil gap G.

  In the state where the handrail 240 takes a parallel posture, for example, when the height of the first support portion 231D is increased according to the physique of the user, the first support column 31 is increased in length. One strut 31 is operated. By this operation, the posture of the handrail 240 is changed so that the inclination angle of the handrail with respect to the gap G is increased. For this reason, the height of the first support portion 231D is higher than the height of the second support portion 232D. At this time, since the height of the second support portion 232D does not change, the height of the first support portion 231D changes independently of the second support portion 232D.

  For example, when the height of the second support portion 232D is increased in a range lower than the first support portion 231D according to the physique of the user, the length of the second support column 32 is increased. The second support column 32 is operated. By this operation, the posture of the handrail 240 changes so that the inclination angle of the handrail 240 with respect to the gap G becomes small. For this reason, the height of the second support portion 232D is brought close to the height of the first support portion 231D. At this time, since the height of the first support portion 231D does not change, the height of the second support portion 232D changes independently of the first support portion 231D.

  As described above, the auxiliary device 10 has a structure in which the length of the first support column 31 and the length of the second support column 32 individually change, and the handrail 240 in the first support portion 231D and the second support portion 232D. Rotating structures cooperate. Thereby, the height of each support part 231D and 232D changes mutually independently. Further, when the length of the first support column 31 and the length of the second support column 32 change by the same length, the height of the handrail while maintaining the relative height relationship between the support portions 231D and 232D. Changes.

  For this reason, the height of 1st support part 231D and the height of 2nd support part 232D can be adjusted according to a user's physique etc., respectively. That is, the height of the first support portion 231D from the heel S and the height of the second support portion 232D from the soil G can be adjusted according to the physique and the like. For this reason, there is a low possibility that the auxiliary device 10 is used while the height of one of the first support portion 231D and the second support portion 232D does not match the physique of the user. For this reason, it can contribute to stabilizing a user's operation | movement.

The intermediate handrail 70 can be curved in the longitudinal direction.
-A 3rd handrail located above the 1st handrail 50 can also be added. In this case, a portion for supporting the third handrail can be provided on the support portion 30, and the first handrail 50 and the third handrail can be connected by an intermediate handrail similar to the intermediate handrail 70. Thereby, the height of the third handrail can be changed independently of the height of the first handrail 50 and the second handrail 60.

  The main body portion 31A of the first support column 31, the main body portion 32A of the second support column 32, the main body portion 33A of the intermediate support column 33, the lower beam 34, the upper beam 35, and the plate 36 can be integrally formed. In short, any configuration can be adopted as long as it is supported by the foundation 20 and can support the handrail 40.

-Only one assembly C can be provided.
-The foundation 20 can be omitted.
-Although the auxiliary instrument 10 was installed in the entrance wall S, it can be installed in any place as long as there is a step other than the entrance wall S.

  -Although the auxiliary instrument 10 was installed in the level | step difference in order to assist the movement of a level | step difference, in order to assist the operation | movement which a user stands up, it can also be installed in a plane. For example, it can be installed on a flat surface to assist in getting up from a futon and getting up from a toilet.
