The invention takes the stair handrail as the track, the walking aid is arranged on each stair handrail, and people can walk up and down stairs by holding the walking aid, and take a step independently but carry most of the weight of the people by the walking aid; the energy accumulator provides power for the running of the walking aid, the walking aid is propped against the walking aid when the walking aid goes downstairs, and the running power energy in the downstairs process is stored in the energy accumulator. When going upstairs, the walking aid is also supported by the walking aid, and the upward power of the walking aid is provided by the energy accumulator.

Description

Energy storage type walking aid mechanism for step ladder
Technical Field
The invention relates to a walking stair additionally provided with an elevator.
Background
At present, buildings with six floors or below are not provided with elevators, so that the buildings are inconvenient to live in, and the positions for installing the elevators are difficult to vacate when the elevators are additionally installed. Walking upstairs is very tiring, and it is equivalent to carry oneself upstairs. Going downstairs seems to be easier, but one step each puts the knee and lumbar spine under a load exceeding the body weight. Easily causing damage to the knee joint and the lumbar.
Disclosure of Invention
The invention takes the stair handrail as the track, the walking aid is arranged on each stair handrail, a person can walk up and down the stairs by being supported by the walking aid, and the walking aid can take a step independently but bear most of the weight of the person, so that the knee joint and the lumbar only need to bear the load far less than the weight; the energy accumulator provides power for the running of the walking aid, the walking aid is propped against the walking aid when the walking aid goes downstairs, and the running power energy in the downstairs process is stored in the energy accumulator. When going upstairs, the walking aid is also supported by the walking aid, and the upward power of the walking aid is provided by the energy accumulator. The running power of the energy accumulator is adjusted by adjusting the pretightening force of the energy accumulator volute spring through the tension pulley.

The specific implementation mode is as follows:
the walking aid is characterized in that rollers (7) are arranged on the upper surface and two sides of a stair handrail (5) in a shell (8) of the walking aid (3) so that the walking aid (3) can roll on the stair handrail (5) and can bear certain lateral force, a brake block (11) is tightly propped against the lower plane of the stair handrail (5), a brake spring (13) is arranged below the brake block (11) and propped against the brake block, the jacking force of the brake spring (13) can be controlled smoothly and finely to control the braking force of the brake block (11), so that the running speed of the walking aid (3) can be controlled smoothly and finely, the brake block (11) is in a normal state when the braking force is maximum, and the walking aid (3) can be stopped on the stair handrail (5) when not used.
The two leaning rods (9) are L-shaped iron pipes, L-shaped vertical arms for going upstairs are arranged below the upper cross arm, L-shaped vertical arms for going downstairs are arranged above the lower cross arm, and the two leaning rods are arranged through hinges (10) and can be folded and unfolded; the leaning rod (9) can also be replaced by a leaning plate (22), and when a person goes up and down stairs, the elbow of the person is pressed against the leaning plate (22) to obtain the walking aid of the walking aid.
The energy accumulator (4) consists of a shell (23), a middle shaft (25), a volute spiral spring (24) and a tension belt (2), wherein the inner end of the volute spiral spring (24) is fixed on the middle shaft (25), and the outer end of the volute spiral spring is connected with the tension belt (2); the spring steel strip for manufacturing the scroll spring (24) is gradually widened from the inner end to the outer end, and the design has the functions that: along with the increase of the winding number of turns of the scroll spring (24), the elastic force of the scroll spring can be increased rapidly, so that the pre-tightening force of the scroll spring (24) can be adjusted only by winding the tension belt (2) on the tension wheel (27), and the running power of the energy accumulator (4) can be adjusted.
For the installation of the energy accumulator, the invention designs two installation modes:
the first installation mode:
the energy accumulator (4) is arranged on a railing (6) below the upper end of each folding stair handrail (5), a fixed pulley (1) is arranged on each stair handrail (5), and a tension belt (2) is connected with a tension wheel (27) in the walking aid shell (8) by bypassing the fixed pulley (1).
The second installation mode is as follows:
the energy accumulator (4) and the walking aid (3) are connected into a whole and arranged at the lower half part of the walking aid (3) to let the brake block (11) be opened, the fixed pulley (1) is arranged at the upper end of the walking aid (3), and the tension belt (2) is connected with a tension wheel (27) fixed at the upper end of the stair handrail (5) after bypassing the fixed pulley (1).
In order to stop the walking aid (3) in situ when the walking aid is not used by people, the running speed of the walking aid can be controlled when the walking aid is used. The invention designs two ways of controlling the running speed and the running force:
the first way to control the operating speed and force:
the leaning rod (9) or the leaning plate (22) is directly arranged on the shell (8) of the walking aid, the floating end of the swinging plate (14) is arranged below the brake spring (13), the lower part of the floating end is propped against by the cam (15), the other end of the swinging plate (14) is hinged with the shell (8) through the small shaft (17), the cam (15) can be operated by the operating lever (12), the operating lever (12) is provided with the torsion spring (16), and the torsion spring (16) has the function of keeping the normal state of the cam (15) at the position of propping against the brake spring (13) so that the walking aid (3) is kept in a stop state when not used.
When going upstairs or downstairs, a cross arm of the leaning rod (9) is unfolded, a person leans against the leaning rod (9) and the shell (8), the operating rod (12) is shifted to enable the cam (15) to reduce the pushing force on the brake spring (13), namely the braking force of the brake block (11) is reduced, the walking aid (3) provides certain upward force to the leaning human body under the action of the pulling force provided by the energy accumulator (4) through the pulling force belt (2), the person can easily walk up and down stairs by virtue of the force, the operation speed and the operation force provided by the walking aid (3) can be operated through the operating rod (12), and the operation amplitude of the operating rod (12) can be widened by the brake spring (13), so that the operation becomes easy.
The second way to control the operating speed and force:
a pressure-bearing spring (19) is arranged in the shell (8), the elasticity of the pressure-bearing spring is larger than that of the brake spring (13), a movable plate (20) is arranged on the side face of the shell, a supporting rod (9) or a supporting plate (22) is arranged on the movable plate (20), a pressure plate (26) is arranged at the upper end of the movable plate (20) and extends into the shell (8) from a pressure plate hole (18) to be pressed on the pressure-bearing spring (19), a supporting plate (21) is arranged at the lower end of the movable plate (20), and the supporting plate (21) is pressed below the brake spring (13) to enable the walking aid (.
When going upstairs or downstairs, the cross arm of the leaning rod (9) is unfolded to be perpendicular to the shell (8), a person can lean on the leaning rod (9) and the leaning plate (20) to walk up and down stairs easily by virtue of force, the running force provided by the walking aid is dependent on the pressure of the person leaning on the leaning rod (9) or the leaning plate (22) and the movable plate (20), the pressure is high, the pressure bearing spring (19) is pressed to be low, the position of the supporting plate (21) integrated with the movable plate (20) is low, the braking force applied to the brake block (11) by the supporting plate (21) through pressing the brake spring (13) is low, the running force provided by the walking aid (3) is high, and otherwise, the running force provided by the walking aid (3) is low.
