When (13) is interrupted and the switch position is changed left and right in the center of the switch, the electric pole of the rising wire of the DC battery (9)

(24) and

(25) When the poles are crossed at the same time and the DC reduction motor 4 rotates clockwise, the foot plate 21 is supported by the floating rod and rises upward.
When the DC reduction motor 9 rotates counterclockwise, the foot plate 21 is supported by the floating rod and goes down to the lower side.
By the operation of the 6-line three-way change switch 26, the footrest 21 of the fully automatic elevating cane 2 of the present invention is formed so as to move upward and downward.
It is coupled with the DC battery while interlocking with the power lines of the DC reduction motor (4) and the upper 6-line 3-way change switch (26).
The operation of the 6-line 3-way change switch in which the power energy of the DC battery is interlocked rotates the first worm gear of the DC reduction motor rotating shaft in which the pole of the DC battery current is changed and repeated and extended clockwise and counterclockwise.
As the power energy of the DC battery 9 interlocks with the DC reduction motor 4, the installed first worm gear 5 and the second worm gear 6 facing the
Upon receiving the rotational motion of the first worm gear 5, the second worm gear 6 changes to a linear motion upward and downward, and the interlocking flow 3 and the second worm gear can move.
[Above] One end of the first worm gear 5 is installed on the rotating shaft of the DC reduction motor 4 and is attached by a hexagonal bolt 7, while meshing with the gear teeth of the second worm gear 6 at the opposite end, DC reduction According to the direction of the axis of rotation of the first worm gear 5 of the motor 4, the second worm gear 6 moves in the upper and lower directions, and the foot plate 21 installed on the connecting rod 2 moves in conjunction.
[Above] The second worm gear 6 is formed by welding protruding from the outer peripheral surface of the upper end of the flow rod 3 in the longitudinal direction.
[Above] In the longitudinal direction of the connecting rod (2), the second worm gear moving through hole (34) is formed to protrude between the grooves, and the gear teeth of the second worm gear (6) of the moving rod (3) are formed.
[Above] The first worm gear (5) installed on the DC reduction motor (4) of the connecting rod (2) and the gear teeth mesh
[Above] Between the grooves of the second worm gear moving through hole 34 installed in the connecting rod, the second worm gear 6 installed in the floating rod can move upward and downward repeatedly.
The second worm gear interlocked with the first worm gear moves, and when the first worm gear rotates clockwise, the foot of the connecting rod rises and rises upward by the support of the floating rod. When the first worm gear rotates counterclockwise, the foot of the connecting rod rises. It is composed of the power of a mechanical gear that goes down by the support of the floating rod, and generates mechanical power to the passive cane, and assists the person to move up and down on the stairs by relying on the footrest installed on the cane.
The safety rubber packing 35, which is seated on the lower end of the flow rod 3, has a circular groove formed as an inner surface and an upper portion of a circular shape, and is seated on the outer surface of the lower end of the flow rod.
A wheel 38 positioned in the longitudinal direction to the lower end of the flow rod 3 and
The movable rod (3) is installed in a pair on the upper side in the horizontal direction and the lower side in the horizontal direction in the vertical direction at the lower side, and two fixed plates 43 are formed.
A pair of through-holes are passed through the center of the two attached fixing plates 43 in the horizontal (horizontal) direction, and in the space between the pair of through-holes
The expansion spring 39 is located in the upper position, and the expansion spring re-barking 40 is located in the lower side,
The screw thread 42 of the center rod on which the wheel 38 is installed penetrates from the lower side of the two fixing plates 43 to the upper side and is fastened with a nut 41 to the thread 42 protruding outward from the upper side of the two fixing plates 43, and The expansion spring control barking 40 is positioned and fixed while
The fixed extension spring control barking 40 is supported with the wheel 38 extending from the lower end of the screw thread 42 to the lower end of the upper extension spring 39 from the lower end of the central bar extending to the lower thread 42 and supporting and pushing the lower end. The upper side of the expansion spring acts as a lifting force that supports and pushes up the fully automatic elevating staff 2 and the user from the ground.
The expansion spring 39 absorbs the weight of the upper part while contracting with the weight of the upper part,
The expansion spring 39 acts to discharge the absorbed weight of the upper part as it expands.
When the fully automatic elevating wand 2 is in a vertical state, the expansion spring 39 is pressed and contracted by the weight of the upper part, and the wheel 38 is changed to an upward position rather than a rubber packing position, so that the wheel 38 action is extinguished and the wheel Instead, the safety rubber packing can be seated vertically while contacting the ground.
If the fully automatic elevating wand 2 moves out of the vertical state and the user drags it or reduces the weight of the fully automatic elevating wand 2 without weight on the footrest (if tilted to the side), the wheel 38 descends with the extension spring's extension force and connects with the ground The fully automatic elevating wand 2 end rubber packing is lifted from the ground and can be moved by wheels, so the wheels roll to prevent damage to the rubber packing, making it convenient to use the fully automatic elevating wand 2.
For the cane user to climb the stairs, the footrest is located preferentially to the lower position of the landing surface in the reverse position, and the weight and feet are lifted and subsequently raised to the upper stair position. It will be reduced by the force of the movement process.
The user of the fully automatic elevating cane 2 of the present invention rises from the position of the lower stairway in the forward direction going down the stairs and raises the foot in the forward direction first on the footrest 21 that is level with the stairs and moves the weight to the foot in the forward direction while moving the footrest After descending (21), land on the lower stair, gather the two feet in the rear car, separate the footrest 21 from the stair surface, and repeatedly raise the footrest 21 at the lower lower stair position by one space in the forward direction to level with the position of the stairway. The power of the gear, which is a machine, constitutes by going down the stairs while repeating to achieve
While going down the stairs, the strength of the foot supporting the weight from the air to the descent is reduced and the use of the leg joints is also reduced. descent wand 2
