The specific embodiment
To combine accompanying drawing and embodiment that this utility model is done further to specify below.
The present invention is the wheelchair of helping the disabled on a kind of machine of large-scale civil aircraft, and is as shown in Figure 1, comprises that backrest 2, handrail 11, seat surface 9, wheelchair support a3, wheelchair support b8, lower limb lean on 7, wheel 6 and seat belt.
The upper rear portion of backrest 2 is fixedly connected hand push 1, is used for wheelchair is carried out, and the side of backrest 2 is provided with handrail 11, and handrail 11 and backrest 2 are connected through adjustable bolt, when wheelchair is packed up, handrail 11 can with backrest 2 on same plane.Lean against and also be provided with seat belt on 2, fixedly the people on the wheelchair guarantees its safety.
As shown in Figure 2, the wheelchair support comprises wheelchair support a3 and wheelchair support b8, and wheelchair support a3, wheelchair support b8 are square structure; Two summits of wheelchair support a3 one end connect two wheels 6 respectively, and wheel 6 is connected with wheelchair support a3 through wheel cover 5, and two summits of wheelchair support b8 one end also connect two wheels 6 respectively; Wheel 6 is connected with wheelchair support b8 through wheel cover 5; And, between two wheels 6, be fixedly connected with lower limb and lean on 7, be used to support people's both feet.Two vertical limits of wheelchair support a3, wheelchair support b8 connect through turning cylinder 4, and together support seat surface 9 makes the wheelchair support of its composition moving axis 4 that can rotate rotate, and realizes packing up of wheelchair, and described wheel 6 can freely rotate.
The limit of the other end that wheelchair support b8 and wheel 6 are corresponding is folding and unfolding rotating shaft 10, and like Fig. 3 and shown in Figure 4, an end of backrest 2 is connected through folding and unfolding rotating shaft 10 with an end of seat surface 9; Backrest 2, seat surface 9 can rotate around folding and unfolding rotating shaft 10, and the limit with the corresponding other end of wheel 6 among the other end of seat surface 9 and the wheelchair support a3 is a buckle type, and seat surface 9 is as shown in Figure 5; One end is provided with snap close 12; During use, the snap close 12 of seat surface 9 one ends snaps on the wheelchair support a3, can normally use; When folding and unfolding stacked, seat surface 9 can be around packing up with backrest 2 shared folding and unfolding rotating shafts 10.State when packing up, as shown in Figure 6.
In this utility model, because wheelchair need not to lean on the occupant to move the diameter D=10mm of four wheels 6 voluntarily in the cabin.The said wheelchair overall dimension of this utility model is:
A) according to domestic 95% male's sitting posture height, add wheel 6 height, consider the backrest comfortableness simultaneously, with reference to first-class cabin chair back height, the wheelchair height overall of confirming to help the disabled on the machine is 1060mm.
B) confirm the wheelchair Breadth Maximum according to large-scale civil aircraft walkway clearance.The economy class width of common large-scale civil aircraft generally is not less than 17in, i.e. 431.8mm.But walkway clearance is stipulated that overhead less than 635mm, visiting number is more than or equal to 20 people's civil aircrafts according to CCAR25.815, its walkway clearance should be less than 380mm, and most of Large Civil Aircraft all belongs to this type of.In order to enlarge the suitability of the wheelchair of originally helping the disabled, confirm that the wheelchair beam overall is 375mm.
C), confirm that wheelchair uses length on the machine according to large-scale civil aircraft economy class array pitch.For satisfying the collapsible folding and unfolding requirement of wheelchair on the machine, it should be deposited between economy seats, or closes at below the seat.Because general large-scale civil aircraft economy seats array pitch is generally 32in, i.e. 812.8mm, wheelchair length is 815mm in confirming to use.
D) according to above requirement, wheelchair is of a size of 1060 * 375 * 815mm in confirming to use.
The wheelchair of helping the disabled on this novel machine uses on the Large Civil Aircraft specially, has taken into full account the minimum walkway clearance requirement of large-scale civil aircraft, considers convenience and folding and unfolding requirement simultaneously, confirms as the collapsible form of packing up.
E), confirm folding size of packing up wheelchair on the machine of back according to depositing convenience and the requirement that realizes mechanism kinematic.After packing up, the height of wheelchair should be less than the seat surface height of typical economy seats on the machine, and the seat surface height of economy class is 400-450mm usually, thus, confirms to pack up the back wheelchair and is of a size of 900 * 375 * 300mm.
F) two wheelchair supports are vertical each other in the use, and the backrest elevation angle is designed to 120 °.
Wheelchair operation instruction on the novel machine:
The occupant boards through ground wheelchair or wheel chair lift after arriving at the airport through other modes of transportation again, or can promptly use the wheelchair of helping the disabled on this novel machine in the boarding gate instead, and it is inner to get into passenger cabin by the hand push that connects firmly behind other people the hand steered backrest 1.
After getting into passenger cabin inside, carry out arriving the seating assignments of different cabins section, unclamp seat belt,, handrail 11 is upwards boosted for conveniently moving to passenger-seat by manpower, be placed on backrest 2 same planes in, and note avoiding damaging.
Before the use, should fasten wheelchair safety belt, seat belt is in the middle of the back of the body pad behind the backrest 2, buckles safe button.In addition, should also be noted that tightening handrail 11 is connected with the bolt of 2 on backrest, prevent that the occupant from not occupying stably and side is fallen.And note tightening wheel 6 and overlap 5 being connected with wheel, prevent wheel 6 free deflection in the moving process, knock seat or other passengers.
In the use, the occupant is put in lower limb with lower limb and leans on 7, and hands can be taken and be placed on above the handrail 11.
For preventing accident, the wheelchair of helping the disabled on this machine should used under the aircraft resting state.
The wheelchair folding and unfolding process of helping the disabled on the novel machine:
After the occupant arrives safe and sound seating assignments, can pack up wheelchair.Specifically the mode of packing up is: at first, two side handrails 11 are upwards boosted, remove the snap close 12 of seat surface 9 and wheelchair support a3, seat surface 9 is upwards started along folding and unfolding rotating shaft 10, till backrest 2 planes.At this moment, the wheelchair support is in free rotary state, can rotate around rack shaft 4.Then, backrest 2 and seat surface 9 are pushed to downwards to the wheelchair support along folding and unfolding rotating shaft 10, and compressed the wheelchair support downwards, till incompressible.At this moment, after the folding and unfolding, wheelchair is of a size of 900 * 375 * 300mm on the machine fully.
After fully folding and unfolding stacked, because volume is less, very little to parking space demand on the machine, wheelchair can be placed under the common economy seats seat on the machine, maybe can leave between storing special-purpose on the machine in.
During use, the process of opening wheelchair is the inverse process that folding and unfolding stacks process.Concrete unfolding mode is: at first backrest 2 and seat surface 9 are pushed to and wheelchair support a3 and the perpendicular position of wheelchair support b8 along folding and unfolding rotating shaft 10, and the wheelchair support is upwards erected to 45 along rotating shaft 4, tighten folding and unfolding rotating shaft 10 this moment.Then, with seat surface 9 along folding and unfolding rotating shaft 10 to transferring to level, the other end snaps on the wheelchair support 8, and locking snap close 12.At last, handrail 11 is pushed into downwards parallel with seat surface 9, and the bolt that is connected with backrest 2 of locking handrail 11, at this moment, wheelchair completion opening procedure can normally use on the machine.
