Real vehicle is the Car for travelling up steps or slope basis of (back claims this car), and the last period, the keystone configuration of real vehicle narrated in literal, describes this car now.

One, on the weight-loading rod (3) humanoid hole (13) is arranged, see Fig. 3, at humanoid hole (13) inside and outside last slice (14) (dotted line is illustrated in the back side) and a following sheet (15) arranged respectively, sheet (14) (15) all has bobbin (16) (17) and retracing spring (18) (19) and locating pin (20) (21) up and down.Have one can contact the pendulum (22) of sheet (14) and (15) up and down at the top of humanoid hole (13), have one (23) and one to put dead axle (24) on the pendulum (22).Hanging has one heavily to put (25) on the hanging axis (26) of sheet (22) outside, and the slotted hole (69) on the pendulum (25) is enclosed within on the pendulum dead axle (24).The function of this mechanism is: when weight-loading rod (3) when being the level of state, heavily pendulum (25) is sagging naturally, and is also sagging naturally by the pendulum (22) of its location, and at this moment, people's pin (5) of connection weight-loading rod (3) and car leg (1) (2) is in the top of hole (13).When weight-loading rod (3) began to lower swing, pin (5) then slided along the first half of humanoid hole (13), and the heavily pendulum (25) on the bar of bowing downwards (3) then tilts to the left side, and sheet (15) can not rotate under the pressure of pin (5) to make pendulum (22) limit down.And last slice (14) are free states, and nail (5) is passed through.When bar (3) when bowing downwards and be returned to level, nail (5) is in the top of hole (13) again.When bar (3) when upwards lifting, heavy pendulum (25) beat to the right, making pendulum (22) limit last slice (14) can not rotate, and makes the nail (5) can be along the lower part slip of humanoid hole (13).The curve design in humanoid hole (13) is: the moving direction of pin (5) in hole (13) be with hole (13) on the contact tangent.Mechanisms such as this humanoid hole, make bar (3) by pin (5) only be friction force, no longer produce cross component, and can exceed bar (3) upper part car leg to real vehicle and remove, the car leg is shortened.Fig. 1 Fig. 4 second has provided the vehicle with hinge (65), and this hinge (65) both can be contained in the two ends of vehicle body (11), can be contained in again in the middle of the vehicle body (11).When being contained in vehicle body (11) centre, its structure is the support (96) that is connected with two (97) with holes on weight-loading rod (3), by the axle connection chain (65) on frame (96) top, chain (65) is connected with vertical rod (10) with axle (09) by hole (97) again, claim Figure 1A type car, such purpose is to allow chain (65) with the same pulling force that all is subjected to of Fig. 4 second.Equally, the humanoid hole (13) of the chain of Fig. 1 (65) with Fig. 3, sheet (14) unit constructions such as (15) replaces up and down.The hole (13) of Fig. 3 is replaced hole (97), leg (2) is pointed on the top of hole (13), nail (5) the replacement axle (09) with Fig. 3 has constituted another vehicle, claims that it is Figure 1B type car.Can remove chain (65) again, allow the axle (09) of bar (10) load onto bearing (110), on the rolling plate (111) that allows bearing (110) be pressed in to be welded on the frame (96), claim that it is Fig. 1 C type car, Figure 19 is its positive side scheme drawing.Firmly comparing of A, B, three kinds of vehicles of C, C type fare power, A type car is more laborsaving, and the Type B car is the most laborsaving, but it is than complexity and cost height.Roll in hole (13) if the nail of Type B car (5) is loaded onto bearing (110), this will be a most desirable labour-saving vehicle.

Two, after the weight-loading rod (3) of real vehicle and vehicle body (11) replace up and down, see Fig. 4 the first and second, the car leg that is exposed at above the vehicle body is plain.Put a sleeve pipe with leg (1) (2) this moment again, sees Fig. 5.Vehicle body (11) is enclosed within on the outer tube (8), and pipe (8) is enclosed within on car leg (1) or (2), and pipe (8) lower end connects a retracing spring (70), and purpose is that pipe (8) is resetted downwards.All there is a lot of lockhole (9) (12) the same side at outer tube (8) and car leg (1) (2).If outer tube (8) and car leg (1) (2) are square tubes, its lockhole (9) and (12) do not have axial rotation in the same side.But axial rotation will take place when all being pipe in outer tube (8) and car leg (1) (2), make the lockhole dislocation.At this moment in car leg (1) (2), be provided with guide frame, see Fig. 5.Guided way (27) is fixed in the car leg, and the guide plate (28) that is fixed on the pipe (8) can slide up and down along guide rail (27), and lockhole on the assurance pipe (8) and the lockhole (9) (12) on the car leg are in same direction.The same with real vehicle, on vehicle body (11), a lockout mechanism is arranged, on the outer tube (8) of this car, lockout mechanism is housed also.Purpose is respectively vehicle body and outer tube, outer tube and car leg to be fixed.The structure of locking is provided by Fig. 6.Latch-up structure is existing the description in real vehicle, and the locking of this car slightly improves.It divides three kinds.Fig. 6 first: in have the wedge (30) of spring (31) to put within cover of wedge (29), pressing a nut (35) with a nut (33), female (35) one sides have a circle bowl (84).One jackscrew (34) is arranged at an end that draws bar (83), and the fixing heart yearn (36) in the brake cable (32).Being locked on the length of this texture ratio real vehicle reduced, and claims that it is the lock wedge.Fig. 6 second: by nut (33) spring (31) and wedge (30) are placed in the cover (29), it is external a support (85), and frame (85) is connected with depression bar (87) by axle (86), when bar (87) when pressing down, can make wedge (30) beat " opening ", claim that it is the pressure wedge.Fig. 6 third specializes in handlebar (7) and lifting (6) outer locking is used: fix a spring (31) and wedge (30) in overlapping (29) by nut, there are one sliding mouthful (93) lower end of wedge (30), there are little spring (89) two ends respectively to push up a globule (88) on the wedge (30), respectively there is a rill (90) in the vertical four directions of cover (29) inner face, and purpose is that pearl (88) is rested in the ditch (90).There is a homalocephalus wedge (30) upper end, can adorn sliding mouthful (93) direction of a knob controlling wedge (30).When as Fig. 6 the third, then can pull out the interior cover (92) of (6) (7) to right-hand lay, knob turn 90 degrees, and cover (92) then can not move in push-and-pull; When knob turn 90 degrees again, cover (92) can advance to the left hand direction.The sleeve pipe (8) on this car leg and the lockout mechanism of Fig. 6 first, along outer tube (8) when moving up and down, outer tube (8) then moves along the car leg at vehicle body (11), equal to have prolonged the car leg length, the lock wedge is stopped on any lockhole (12) (9), shortened the car leg, make this car outward appearance more good-looking.Its use is that the locking of two on vehicle body (11) and the outer tube (8) is wanted synchronously, uses a rim brake (64) control jointly.Figure 29 first and second is the another ways that shorten the upright leg of car.The length of upright leg (1) or (2) and vehicle body standpipe (11) of picking up the car is suitable.First figure is the vehicle body standpipe in upright leg outside, and weight-loading rod this moment (3) can connect on the leg frame (4) of being drawn by the horizontal leg of car, or is connected the leg frame (4) of being drawn by upright leg heel and goes up (see figure 1), is connected on the hole (66) by nail (5).Second figure be the vehicle body standpipe at upright leg inside, available nail (5) is connected in weight-loading rod (3) on the hole (66) of leg (1) or (2).On the upright leg or lower end and vehicle body standpipe on or the lower end ring set (173) and (175) up and down all are housed, ball (174) is arranged in the ring set, purpose is when allowing the vehicle body up-and-down movement, utilizes rolling, reduces resistance.

When three, Jian Che or real vehicle were gone upstairs, all having run into had grip or outstanding muscle (48) on step, and this has increased very large resistance for 10 centimetres of caster wheeles of about φ, and in order to overcome it, this car has adopted the Ramp bridge device.See Fig. 7: both sides are sloping wall (37), and the centre is the Ramp bridge of (39) at the bottom of the Ramp bridge, and sloping hole (38) is arranged on the wall (37), can make caster axle (80) movable in the hole.One end of slope wall (37) has a spring chamber (40), and spring (41) is put within it.One end of wall (37) has a trap (44), and with screw (45) according to need being fixed on the wall (37).There is a usefulness screw (42) to connect the plate washer (48) that can rotate under the plate (44).The packing ring (49) of one position adjustable is arranged on the caster axle (80), see Fig. 8, the fixing spring shelves (50) of an end are arranged on the circle (49).When using Ramp bridge, this car castor (52) is loaded onto Ramp bridge, trap (44) is fixed on the wall (37), and the other end of the spring (41) of chamber (40) is put into spring chamber (43) on the car leg (2) (1) with screw (45).Vacancy part under wall this moment (37) is put the top at the anti-skidding muscle (48) of stairway step.This car (39) at the bottom of the bridge is advanced, and make spring (41) compression, the shelves (50) on the caster axle (80) slide (38) lower edge along the hole, after wheel (52) goes along a bridge at the end (39), grade (50) have been entered in the hole tooth (47) on the hole (38).When wheel (52) halts or when just having begun to rise, shelves (50) can not move forward under the effect of spring (41) limiting Ramp bridge under the prevention of tooth (47).When castor (52) continue to raise about ten centimetres the time, Ramp bridge will rotate and make shelves (50) to leave tooth (47) under the prevention of spring fixed (51) under the influence of deadweight.At this moment under the effect of spring (41), Ramp bridge is forwards moved, be returned to initial condition, this is the situation upstairs the time.As the Ramp bridge device is strengthened, and to put on the road surface of a upward slope, (39) were level at the bottom of adjustment trap (44) made bridge, and plate (46) is rotated an angle of 90 degrees, made it not expose the lower edge of plate (44), and at this moment this car of Ramp bridge has been installed, and had become a grade climbing vehicle.Make original slope route, become the lifting of weight, the sawtooth slope route of translation.When this car only has four castors (52), during the desire climbing, can on four wheels (52), all load onto Ramp bridge.The Ramp bridge size is exceeded with leg before and after not influencing, or left and right sides car leg is made into not parallel shape, and promptly the front and back leg staggers, and avoids the shadow noon to Ramp bridge.If when transition wheel (54) being arranged or cardan wheel (112) is arranged as this car, add relatively difficulty of Ramp bridge at trailing wheel, can only on two front-wheels, adorn Ramp bridge.At this moment two front-wheels can march forward along Ramp bridge, and two trailing wheels only play fixed pedestal, prevent the lock that falls back so two trailing wheels will be equipped with.The anti-retrogression lock is provided by Figure 16, and it is the principle that Fig. 6 locks, and only is spring deflection, is become by normal " group of closing " attitude and often " opens " shape.The wedge (30) that has lock stifled (94) can be inserted between wheel (52) and the castor fork blocking up (94), prevents wheel (52) reversing.Cover of wedge (29) is fixed on the car leg (2) with a muscle (95).The rim brake of control stifled (94) can be placed on lifting on (6) or the handlebar (7).This lock uses when only playing a supportive role when climbing.

When four, real vehicle is gone downstairs on pushing away the people, can be laborsaving more than 60%.When weight is 200 jin, if laborsaving 60%, then to pay about 80 jin of power and just weight can be pushed to the building, this is that people are unacceptable.Because the power that people can pay usually only is 30 jin, pay 80 jin of power, and be that a hand is exerted oneself, be that ordinary person does not accomplish.In order to adapt to ordinary person's limit of power, this car will shorten front and back leg spacing, promptly reduce the weighing arm of lever.Wheel base after dwindling from, less than the half as much again step width, caused and climbed the building difficulty, so will add transition wheel.This car just can increase transition wheel (54) when bearing a heavy burden more than 100 jin, see Fig. 9, and it is to increase transiting rod (55) is arranged before this back wheels of vehicle, and bar has a slotted hole on (55), and will take turns (54) with screw and fix.It need be single arm(ed) lever or multi-arm bar that bar (55) can be complied with.Fig. 9 first is that the single arm(ed) lever (55) of two leg cars increases the scheme drawing that two transition wheels (54) are arranged, and Fig. 9 second is double armed lever (55) scheme drawing of a transition wheel (54).Four leg bassinet structures are identical, and it is to connect rod (55), tight pulley (54) again from leg (2).General run of thins is placed on rim brake (64) on (6) or (7), and when last going downstairs, when the trammer left car, rim brake (64) can cut out wedge (29), and the vehicle body locking is not fallen.The rim brake (64) that transition wheel (54) car is installed can be in a certain position that " ON state " is placed on car body, because use transition wheel (54) and the Area of bearing of two front truckles (52) when climbing the building littler than the bearing surface of four castors 52, when going up downstairs, the trammer can not leave car, otherwise car will skew, wait to climb the building process and finish, when not using lifting, close rim brake (64) again (6).

Five, in order to enlarge the field of application of real vehicle, on real vehicle, increase by two bull wheels and become the wheel Wheel-chair, make the rider not leave car and just can go up downstairs.Its structure is, sees Figure 10 (side of drawing), in vehicle body (11) both sides one guide plate (57) arranged respectively, and guide plate structure is seen the birds-eye view of Figure 11.Climb hole (60) on the guide plate (57), dress wheelchair wedge (59) in hole (60), guide plate (57) built-in has the centering block (56) of wheel shaft (58), and wheel shaft (58) can be placed bull wheel (113).The structure of wedge (59) is with Fig. 6 first.The rim brake (67) that to control wedge (59) during use can be according to being fixed on the wheelchair armrest or on (6) (7).When lock (67) is on wheelchair armrest, by the rider wedge (59) is beaten " opening ", centering block (56) is positioned on the wedge (59), bull wheel this moment (113) is liftoff can climb the building.If travel on the level land, assist by the trammer, centering block (56) is positioned under the wedge (59), bull wheel (113) is landed, the rider can oneself handle the translation of this car.Taking advantage of people's seat is to connect about vehicle body (11) and to make backrest and handrail, the people is seated in.

Six, in order to make this car platform of climbing, this car the junction of (6), in the junction of vehicle body (11) with handlebar (7), is designed to the mechanism that can back and forth control in weight-loading rod (3) and lifting, sees Figure 12.On bar (3) and vehicle body (11), be fixed with orifice plate (61), a centre hole and a plurality of circumferential apertures are arranged on the
