By taking the first executing agency as an example：Worm screw is meshed with turbine, then when scroll bar no longer drives turbine to rotate, worm screw
It will be in self-locking state with turbine, and then support rod will not generate rotation, ensure that the pedal on support rod is in horizontality
Or can well securely when heeling condition, the pedal in horizontality avoids after the person of going upstairs sets foot on pedal and generates rolling
It is dynamic, protect the person of going upstairs；Pedal in heeling condition avoids wheelchair pedal when moving on pedal and generates shaking, guarantees
The pedal of wheelchair energy safety heeling condition.
In the present invention, support rod through on support rod support ring set and third support plate drive pedal around support rod axis
Rotation.
For swing mechanism：The two sides of hinged block pass through pin and are mounted on two side plates of U-shaped board, then hinged block can
Around the rotation of the axis of pin.For scroll spring, during hinged block rotates counterclockwise around the axis of pin, scrollwork
Spring is compressed；Under the reset force of scroll spring, hinged block surrounds the axis both clockwise spinning reduction of pin.Sliding long block passes through

Compression, in this way sliding long block can carry out sliding in hinged block automatically under being extruded, and guarantee the whole service of swing mechanism.Gear
The effect that block is matched with corner block, transition plates with accommodating groove respectively is：First, under the stirring of block, sliding long block is surrounded
The center of hinged block rotates counterclockwise, and during sliding the rotation counterclockwise of long block, block is along the side for sliding long block
The sliding in face, block enter in accommodating groove through corner block and transition plates, and sliding long block at this time is pasted substantially with corresponding pedal
It closes, is thus avoided that block will slide long block branch, making to slide can not be preferably bonded between long block and corresponding pedal.
Second, during pedal swings to horizontality from heeling condition, pedal drives block to be detached from from accommodating groove, then exists
Under the reset force of scroll spring, hinged block drives sliding long block to rotate clockwise around the center of hinged block, and block relatively can
To sliding long block there is one end of fillet to slide through transition plates and corner block, behind pedal swinging horizontal position, block stops
Movement.Partition is mounted between two sliding long blocks by two connecting plates, then two sliding long blocks can be through connecting plate band
Dynamic dividing plate is swung.The two sides of accommodating groove have fillet, drive block to be detached from from accommodating groove convenient for pedal.
Deform stair in normal state, all pedals are in horizontality, only are needing to deform in use, stepping on
Plate can just be deformed into heeling condition.Assembly for deformation stair of the invention：The residential building table top at mouth of entering is generally all high
In ground, the side hole that one is placed deformation stair is needed on the ground and is deformed in stair after deformation stair are placed into
Pedal in the step mechanisms of end can be above the ground level certain distance, after being in heeling condition so as to the pedal in the step mechanisms of end
With after ground face contact formed a small slope, convenient for wheelchair is pushed to；First step mechanism in deformation stair is close to entering
Table top at mouthful, and the pedal in first step mechanism can be lower than table top certain distance, so as to the pedal in first step mechanism
A small slope is formed with deck contact after heeling condition, convenient for pushing to wheelchair.
When deform stair be in normal condition when, when scroll spring be in uncompressed deformation state, sliding long block with 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 undeformed, 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 support rod will not generate rotation, ensure that the pedal pedal when in a horizontal state on support rod
It will not shake, ensure that the safety after people set foot on pedal.
Deform stair it is undeformed 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 movement of end step mechanisms with handle panel.Handle panel exists
Rotation rotates shaft under external force, and shaft drives worm screw to rotate through driving bevel gear, transmitting bevel gear.Worm screw energy while band
Turbine, the turbine in second step mechanism, the turbine in third step mechanisms, end step mechanisms in dynamic first step mechanism
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 support rod to rotate clockwise through turbine, and support rod is through on support rod
Support ring set and third support plate that pedal is driven to rotate around support rod axis both clockwise.
Pedal in the pedal and second step mechanism in first step mechanism rotates clockwise inclination from horizontality
During, for first step mechanism：Pedal drives hinged block to rotate around the axis both clockwise of support rod through U-shaped board；It is right
In second step mechanism：Pedal drives block to rotate around the axis both clockwise of support 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 support rod
In the effect and second step mechanism rotated clockwise under the toggle action of block, sliding long block drive side fixed plate is to hinged
Block direction is mobile, 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
Guarantee the whole service of swing mechanism in first step mechanism.It is stirred in first step mechanism in the block in second 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 in accommodating groove block through corner block and transition plates；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 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 inclination, one end of the pedal in first step mechanism forms a small slope with the deck contact at mouth of entering, the
Pedal in one step mechanisms matches transition with the pedal in second step mechanism by the partition in first step mechanism, the
Pedal in two step mechanisms matches transition with the pedal in third step mechanisms by the partition in second step mechanism, the
Pedal in three step mechanisms matches transition with the pedal in the step mechanisms of end by the partition in third step mechanisms, end
A small slope is formed after one end of pedal in tail step mechanisms and ground face contact；Finally, after the deformation of whole deformation stair, just
A complete stair slope is constituted, such wheelchair is easy to shift the platform from mouth of entering onto through complete stair slope from ground
On face, when avoiding the designs of some residential buildings and not supplying the small slope of wheelchair for disabled, wheelchair needs more people's resultant forces to lift
The trouble on table top at mouth of entering also considerably increases the convenience that disabled person passes in and out residential building.Meanwhile the design of structure
It also ensures that the pedal in heeling condition will not generate shaking, ensure that wheelchair can be smoothly from ground to table top.
When deformation stair need to be restored to normal condition, handle panel is reversely rotated, and shaft is bored through driving bevel gear, transmitting
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 support rod of structure, third step mechanisms and end step mechanisms reversely rotates so that pedal be restored to from heeling condition it is horizontal
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
Transition plates, 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 utilize worm screw to transmit, first step mechanism,
Second step mechanism, third step mechanisms and end step mechanisms are able to achieve synchronization action；For swing mechanism, it is in pedal
When horizontality, partition 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
After end step mechanisms complete rotation inclination, one end of the pedal in first step mechanism and the deck contact shape at mouth of entering
At a small slope, the pedal in first step mechanism passes through in the partition and second step mechanism in first step mechanism
Pedal matches transition, and the pedal in second step mechanism passes through in the partition and third step mechanisms in second step mechanism
Pedal matches transition, and the pedal in third step mechanisms passes through in the partition and end step mechanisms in third step mechanisms
Pedal matches transition, forms a small slope after one end of the pedal in the step mechanisms of end and ground face contact；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 on the table top at mouth of entering, and avoids wheelchair and more people's resultant forces is needed to carry on the trouble carried off from stair.Knot of the present invention
