摘要： PROBLEM TO BE SOLVED: To reduce noise generated by engagement and to improve reliability by providing a shock absorbers on an outer periphery of a footstep chain roller, constituting the shock absorbers on a protruded part with an optional interval and arranging it so that height of the protruded part differs. SOLUTION: Shock absorbers 11a, 11b are provided on an outer periphery of a footstep chain roller 5. A plural number of the protruded parts 11a having step differences h2 are provided in the inside of width W of the footstep chain roller 5, and a plural number of the protruded parts 11b protruded by h1 from surface of the shock absorbers are provided against them. The height h1, h2 is to be dimensions in consideration of deformation quantity at the time when the extreme outside protruded part 11a collides against a tooth bottom surface 4a of a footstep sprocket 4. Width W1 of the protruded parts 11a is made to be roughly the same as width W2 of the protruded parts 11b or larger. Additionally, spring rigidity of the protruded parts 11a and the protruded parts 11b can be different from each other. Consequently, even when an engagement position of the footstep chain roller 5 and the footstep sprocket 4 is changed, it is possible to extensively reduce noise due to an engagement shock.

摘要： PROBLEM TO BE SOLVED: To absorb the impact force to be generated in the engagement, to keep the stable condition of a toothed rotary body side, and to synchronize the phase for excellent engagement by engaging a power transmission body with the toothed rotary body in the direction perpendicular to the advancing direction of the toothed rotary body. SOLUTION: Only a stepped guide rail 10 side which is rotatably and elastically supported is once pressed and detached from a guide roller 13. That means, a power transmission body 5 is once detached from a toothed rotary body 6. The guide roller 13 receives the reaction of an elastic body 12, and supported by a guide rail 10A which is fixed and supported, and the guide roller 13 is engaged with a free-moving rotary body 16, and rotated in a stable condition. When the guide roller 13 enters the section R, the stepped guide rail 10 gradually approaches the guide roller 13 along the inclined surface, and the power transmission body 5 gradually approaches the toothed rotary body 6 because the stepped guide rail is provided with the elastic body 12 on the back side.

摘要： PURPOSE: To simplify the structure and action of a tilt step tread by interlocking a mechanism keeping the tilt step tread horizontal and a mechanism inclining it. CONSTITUTION: Atilt step thread 17 can be inclined except for narrow step treads 18 on both sides in the width direction of a specific stairway and risers 18R continued to them. Step tread support rods 20 protruded or submerged toward an inner wall body 18W are provided on both sides in the width direction of the step tread 17 on the back face side to support the tilt step tread 17 at the same plane as that of the narrow step treads 18 during the normal operation. Tilt keeping arms 24 are interlocked with the step tread support rods 20 extruded by driving apparatuses 21 after the conveyance of a wheelchair is completed and block the surface of a riser 17R with their tips. The step tread support rods 20 can be protruded or submerged on the surface of the riser 17R by the power of the driving apparatuses 21, and the structure and action of the tilt step tread 17 can be simplified.

摘要： PURPOSE:To easily and accurately guide a footstep to the home position of a base bed and to always maintain it in a home position by providing a positioning guide device fixed at a moving footstep, a bracket fixed to the base bed, and a rotatable roller attached to the bracket. CONSTITUTION:When moving footsteps 4' and 5' to effect transformation to a wheelchair format or an ordinary format are induced by a front footstep, a positioning guide device 9 is induced by a bracket 11 fixed to a base bed 10 and a rotatable roller 13 attached to the bracket 11. Even when a backlash occurs to a fixed hook 18 and parallel links 6a and 6b, the deviation of the orbits in a longitudinal and the vertical direction of the moving footsteps 4' and 5' is corrected and guide along a regular orbit is easily effected. When the footsteps 4' and 5' are contained in the base bed 10, the moving footsteps 4' and 5' are accurately contained and fixed in the home position of the base bed 10 and can be always maintained in the home position of the base bed 10.
