When deform stair be in normal condition when, when scroll spring be in uncompressed deformation state, slide long block and accordingly
Block be in contact.
For deforming first step mechanism, second step mechanism, third step mechanisms and end step mechanisms in stair,
Four workflow is identical.
When deformation stair are not deformed, by taking first step mechanism as an example：When scroll bar does not drive turbine to rotate, worm screw and whirlpool
Wheel is in self-locking state, and then supporting rod not will produce rotation, ensure that pedal when the pedal on supporting rod is in horizontality
It will not shake, ensure that the safety after people set foot on pedal.
Deform stair it is not deformed when, have between the pedal in pedal and second step mechanism in first step mechanism every
Plate when just the person of going upstairs being prevented to go upstairs in this way, accidentally clips to foot in the gap between two pedals as barrier, protects
The person of going upstairs is protected.
When wheelchair needs to push to table top from ground using deformation stair, stair modified flow is deformed：User is by making
Make first step mechanism, second step mechanism, third step mechanisms and the action of end step mechanisms with handle panel.Handle panel exists
Outer force effect backspin turns that shaft is made to rotate, and shaft drives worm screw to rotate through driving bevel gear, transmission bevel gear.Worm screw energy while band
Turbine in dynamic first step mechanism, the turbine in second step mechanism, the turbine in third step mechanisms, end step mechanisms
In turbine synchronous rotary, then first step mechanism, second step mechanism, third step mechanisms, end step mechanisms can be same
Step operation.
By taking first step mechanism as an example：Worm screw drives supporting rod to rotate clockwise through turbine, and supporting rod is through on supporting rod
Support ring set and third support plate that pedal is driven to be rotated around supporting rod axis both clockwise.
The pedal in pedal and second step mechanism in first step mechanism rotates clockwise inclination from horizontality
During, for first step mechanism：Pedal drives hinged block to be rotated around the axis both clockwise of supporting rod through U-shaped board；It is right
In second step mechanism：Pedal drives block to be rotated around the axis both clockwise of supporting rod, and block is stirred in first step mechanism
Sliding long block.
For the sliding long block in first step mechanism：Hinged block in first step mechanism surrounds the axis of supporting rod
In the effect rotated clockwise and second step mechanism under the toggle action of block, sliding long block drive side's fixed plate is to hingedly
Block direction moves, and hinged block spring is compressed, while sliding the axis that long block drives the hinged block in first step mechanism to surround pin
The rotation of line, scroll spring are compressed；Pedal in this way in first step mechanism rotates clockwise inclination and second step machine
Under the action of pedal in structure rotates clockwise inclination, pedal in first step mechanism and the pedal in second step mechanism it
Between distance it is shorter and shorter, then sliding long block can carry out automatically sliding in hinged block under the extruding of two pedals,
And slide long block and rotated counterclockwise around the center of hinged block, sliding long block is through connecting plate band dynamic dividing plate counter-clockwise swing, finally
Ensure the whole service of swing mechanism in first step mechanism.Block in second step mechanism is stirred in first step mechanism
Sliding long block during, sliding long block rotates counterclockwise around the center of hinged block, and in the rotation counterclockwise of sliding long block
During turning, along the sliding of the side of sliding long block, block enters through corner block and rebound in accommodating groove block；This
When, the pedal in pedal and second step mechanism in first step mechanism, which rotates, to be tilted a certain angle, first step machine
Sliding long block in structure is bonded substantially with the pedal in second step mechanism, then the partition board in first step mechanism and second
Pedal in rank mechanism is also bonded substantially.
In conclusion when first step mechanism, second step mechanism, third step mechanisms and end step mechanisms are completed
After rotation tilts, one end of the pedal in first step mechanism with into the deck contact at doorway form a small slope, the
Pedal in one step mechanisms matches transition by the partition board in first step mechanism with the pedal in second step mechanism, the
Pedal in two step mechanisms matches transition by the partition board in second step mechanism with the pedal in third step mechanisms, the
Pedal in three step mechanisms matches transition by the partition board in third step mechanisms with the pedal in the step mechanisms of end, end
One end of pedal in tail step mechanisms forms a small slope after being contacted with ground；Finally, after the deformation of whole deformation stair, just
A complete stair slope is constituted, such wheelchair is easy to shift the platform into from doorway onto through complete stair slope from ground
On face, when being designed without slope small for wheelchair for disabled of some residential buildings is avoided, wheelchair needs more people's resultant forces to lift
To the convenience for into the trouble on the table top at doorway, also considerably increasing disabled person's disengaging residential building.Meanwhile the design of structure
It also ensures that the pedal in heeling condition not will produce shaking, ensure that wheelchair can be smoothly from ground to table top.
When deformation stair need to be restored to normal condition, handle panel reversely rotates, and shaft is bored through driving bevel gear, transmission
Gear drive worm screw reversely rotate, worm screw can drive simultaneously the turbine in first step mechanism, the turbine in second step mechanism,
Turbine in turbine, end step mechanisms in third step mechanisms reversely rotates, then first step mechanism, second step machine
The supporting rod of structure, third step mechanisms and end step mechanisms reversely rotates so that pedal is restored to horizontal from heeling condition
State.During pedal is rotated to horizontal state, under the reset force of scroll spring, hinged block drives sliding long block to swing
To home position.
By taking the block in second step mechanism resets as an example：When pedal swings to from heeling condition the process of horizontality
In, pedal drives block from being detached from the accommodating groove of hinged block in first step mechanism, relatively can be along first with backstop
Rebound, corner block and the side sliding for sliding long block in step mechanisms；Behind pedal swinging horizontal position, block stops fortune
It is dynamic.
Relative to traditional stairway art, the effect that deformation stair of the invention are transmitted using worm screw, first step mechanism,
Second step mechanism, third step mechanisms and end step mechanisms can realize synchronization action；For swing mechanism, it is in pedal
When horizontality, partition board can play the role of the gap barrier between two adjacent pedals to protect the person of going upstairs；Sliding
Long block can carry out automatically sliding in hinged block in the case where being extruded, and avoid two adjacent pedals and can not rotate simultaneously and incline
Oblique phenomenon ensure that the whole service of swing mechanism.When first step mechanism, second step mechanism, third step mechanisms and
End step mechanisms are completed after rotation tilts, one end of the pedal in first step mechanism with into the deck contact shape at doorway
At a small slope, the pedal in first step mechanism passes through in the partition board and second step mechanism in first step mechanism
Pedal matches transition, and the pedal in second step mechanism passes through in the partition board and third step mechanisms in second step mechanism
Pedal matches transition, and the pedal in third step mechanisms passes through in the partition board and end step mechanisms in third step mechanisms
Pedal matches transition, and one end of the pedal in the step mechanisms of end forms a small slope after being contacted with ground；Finally, entirely
After deforming stair deformation, a complete stair slope is just constituted, such wheelchair is easy to oblique through complete stair from ground
Slope is shifted onto on the table top at doorway, avoids wheelchair and more people's resultant forces is needed to carry on the trouble carried off from stair.Knot of the present invention
