Description
Technical field
The present invention relates to stair climbing wheelchair manufacturing technology field.
Background technology
In stair climbing wheelchair manufacturing technology field, divide by stair climbing principle, there is star wheel type, crawler type, vertical liter at present
Drop formula.Star wheel type stair climbing wheelchair wants demanded driving force big, it is necessary to driven by power, operation is not steady enough, and wheelchair is from great, it is difficult to
Carry, steering is dumb in stair, and storage space-consuming is big, is difficult to realize and is delivered in automobile trunk.Crawler type stair climbing wheel
Chair needs driven by power, damages stair, and cost is high.Vertical lift type stair climbing wheelchair needs driven by power, complex operation, wheelchair
It is big from great, difficult, storage space-consuming, it is also difficult to realize and delivered in automobile trunk.
For the old man of the upper inconvenience downstairs stayed in building there is an urgent need to a kind of simple in construction, action is simple, cheap, light
Easily carry, with vehicle carrying, can stair climbing, and can is in the up wheeled chair in level land.The old man of upper inconvenience downstairs is seated under wheelchair
Building, in front of the car, old man goes on a long journey in sitting enter car, and wheelchair is mounted in automobile trunk, after reaching purpose, then from boot
Taking-up wheelchair, can be sitting on wheelchair and stroll in the park, market, lift living space and the quality of life of handicapped old man.
Utility model content
To solve the above problems, it is an object of the invention to provide a kind of stair climbing for cutting brace type lifting, slide rail type translation
Wheelchair, operate steadily, it is simple to operate, can be run on level land, can disassembled simply, light portable wheelchair can be common
Family-sized car boot carries, and is easy to deposit, cheap, can greatly lift the downstairs living space of inconvenient old man and life
Bioplasm amount.
In order to realize foregoing invention target, cut support lifting sliding rail present inventors have proposed one kind and translate detachable stair climbing

Embodiment
With reference to accompanying drawing 5-13, illustrate implementation steps of the invention below.
Plane origin position, see accompanying drawing 5：The housing car is in ground level position, each 1 front-wheel in left and right（11）, or so
Each 1 trailing wheel（14）Contacted with ground, each 1 housing folding supporting legs in left and right（25）In folded state, 1 each with left and right outer
Frame supporting leg（24）With respect to 0 degree, each 1 housing supporting leg in left and right（24）Lower surface is higher by 70mm or so than ground;Described cuts
Brace type elevating mechanism is in closure state, and upper ledge (1) and lower frame (2) relative distance are zero, crank handle（15）With rocking arm（16）Into
During straight line, hand handle arm is put into（27）On, limit crank handle（15）Rotation, while limit ball-screw（8）Rotation, plays liter
Brake effect is dropped;The folding supporting legs slide rail type translation mechanism is in uppermost position, each 1 front support leg in left and right（9）, it is left
Right each 1 rear support leg（19）Apart from ground level 70mm or so, middle part folding supporting legs behind each 1 of left and right（20）In rugosity
State, 1 rear support leg each with left and right（19）Relative angle be 0 degree, in this plane origin position, whole wheelchair can with it is common
Wheelchair is the same, freely walks in the plane.
Housing vehicle seats rise, and see accompanying drawing 6：Crank handle (15) is folded to rocking arm (16) along jointed shaft, with rocking arm (16) into 90
Spend angle, crank handle (15) rotate counterclockwise, by cutting brace type elevating mechanism internal structure operation principle, behind each 1 of left and right
Supporting leg（19）1 front support leg each with left and right（9）4 points first move down 70mm contacts ground, form support, then upper ledge（1）Phase
To lower frame（2）The distance of a mobile shoulder height, housing car, seat is driven to rise the distance of a shoulder height, left and right each 1
Individual front-wheel（11）, each 1 trailing wheel in left and right（14）Reach the height with one step distance of ground distance.
Housing vehicle seats translate, and see accompanying drawing 7:Hold each 1 hand handle arm in left and right（27）Housing car and seat are promoted, by flat
Telephone-moving structure, make the distance of housing car and seat relatively 1 step width of plane origin position translation, each 1 front-wheel in left and right
（11）Move on to the innermost end of step 1;Each 1 housing supporting leg in left and right（24）Now there is 1 step plus 70mm's apart from ground
Distance, each 1 housing folding supporting legs in left and right（25）1 housing supporting leg each with respect to left and right（24）Do 180 degree expansion and become one
Bar straight line, to be adapted to the difference in height between two stairway steps, pass through each 1 housing adjustable support foot in left and right（29）Fine setting, with suitable
Different stairway step height are closed, each 1 front-wheel of or so is contacted with ground（11）On step 1 and each 1 housing in left and right is adjustable
Support feet（29）Four-point supporting is formed to housing car and seat on the ground, it is ensured that housing car and seat are remained and put down with ground
OK.
Translation mechanism rises, and sees accompanying drawing 8:Crank handle (15) is clockwise into 90 degree of angles, crank handle (15) with rocking arm (16)
Rotation, passes through elevating mechanism internal structure operation principle, lower frame（2）With respect to upper ledge（1）The distance of mobile 1 shoulder height, band
Dynamic translation mechanism rises the distance of a shoulder height, each 1 rear support leg in left and right（19）Now apart from the height of 1 step in ground
Spend, middle part folding supporting legs behind each 1 of left and right（20）Expansion, 1 rear support leg each with left and right（19）Relative angle is 180 degree,
Straight line is formed, adjusts middle part adjustable support foot behind each 1 of left and right（22）, to be adapted to different stairway step height, with ground
Contact, each 1 front support leg in left and right（9）Apart from the height of 1 step in ground.
Translation mechanism translates, and sees accompanying drawing 9：Promote translation mechanism to translate the distance of a step width, propped up before each 1 of left and right
Support leg（9）Move on to the innermost end of step 1, middle part adjustable support foot behind each 1 of left and right（22）Prop up on the ground before 1 each with left and right
Support leg（9）The four-point supporting on step 1, it is ensured that translation mechanism remains parallel with ground.
Housing vehicle seats rise, and see accompanying drawing 10:Crank handle (15) is folded to rocking arm (16) along jointed shaft, with rocking arm (16) into 90
Angle is spent, crank handle (15) rotate counterclockwise, passes through elevating mechanism internal structure operation principle, upper ledge（1）With respect to lower frame（2）Move
The distance of a shoulder height is moved, drives housing car, seat to rise the distance of a shoulder height, each 1 front-wheel in left and right（11）
Reach the position for being higher by step 2, each 1 housing folding supporting foot in left and right（29）Reach the position for being higher by step 1.
Housing vehicle seats translate, and see accompanying drawing 11:Hold each 1 hand handle arm in left and right（27）Housing car and seat are promoted, is passed through
Translation mechanism, housing car and seat is set to translate the distance of a step width, each 1 front-wheel in left and right（11）Move on to step 2 most
Inner end;Each 1 housing folding supporting foot in left and right（29）Move on to the outer end of step 1, each 1 front-wheel in left and right（11）On step 2 and
