In general, dwelling house stair 1 are connecting wall 5 in the one side, and its opposite side is provided with a guardrail 2.According to architectural design standard, the structural strength of guardrail should be enough to grantee or crowd's the pressure of pushing.As shown in Figure 1, the dwelling house stair generally are Zigzag type stair 1, promptly roughly be provided with a belly board 3 between the aspect platform 4 of contiguous floors at the intermediate altitude place, stair lead to this belly board 3 from an aspect platform 4, and then turn back and get back to adjacent aspect platform.Like this, can reduce occupied space of stair and steepness thereof.

According to the present invention, on a flight of stairs 1, can assemble a walker 10, the latter has a cover idler wheel mechanism 14, referring to shown in Figure 2.Trend along stair 1 is provided with a trapped orbit 15, and the latter is fixed on stair 1 or its guardrail 2, and certainly, guardrail itself also can doublely be done track and use.

Walker 10 forms to roll with trapped orbit 15 by idler wheel mechanism 14 and engages, and can roll along trapped orbit under the effect of a tractive force and walk.For this reason, those of ordinary skill in the art can dream up various idler wheel mechanisms, as long as can the safe bearing load walker and on normal load.

And carrier 10 has one and stretches to the horizontal bearing frame 11 of stair top perpendicular to trapped orbit or guardrail, and its extension elongation is enough carried next adult and get final product, and its terrace height from stair 1 can be chosen to be according to design and be used for standing people or seat people.

Be, carrier 11 is foldable to the parallel position of pressing close to guardrail 2, does not influence the large scale goods so that when not using it is collapsed or a great number of people am current.Those of ordinary skill in the art can be between walker 10 and carrier 11 the various folding of design and installation mechanism, as long as can be durable flexibly.

A motor reducer mechanism 30 is linked up with walker 10 and apply tractive force by a cable means to the latter.In preferred embodiment shown in Figure 2, motor reducer mechanism 30 almost fixed and are fixed two isodiametric elevator rollers 31 and 32 on its output shaft (not shown) near the turning of Zigzag type stair 1.For the Zigzag type stair, an end of elevator cable 21 is linking one of them elevator roller 31, and its other end strides across a dead sheave 22 and extends to the walker 10 on the left side and be fixed thereon, promptly attachment point 21 '.Article one, interlock cable 23 extends through trapped orbit 15 near motor reducer mechanism 30 end far away and through a bend pipe 22 ' detour 180 ° from the point of contact of this walker, interlock cable 23 near the near-end of trapped orbit, extend again thus and at this through another bend pipe 22 ' rotate 180 °, stretch to the right walker 10 thus again and fix on it.One end of another elevator cable 21 is fixed to attachment point 21 on this walker 10 ' locate, its other end then stretches near the far-end of trapped orbit 15 and at this and rotates about 180 ° through a pulley 22, stretches to another elevator roller 32 of installing in the motor reducer mechanism 30 thus again and reels on it.In order to make this another elevator cable 21 aim at elevator roller 32 better, can on its walking path, set up two displacement pulleys 22 ".

In fact, above-mentioned bend pipe 22 ' can be substituted by pulley is realized thus walking cable more smoothly, and is alleviated the wearing and tearing to cable, and saves electric energy.

In cable means shown in Figure 2, the lead of elevator roller 31 and 32 pairs of elevator cables 21 is just in time opposite, thereby makes two walkers 10 move toward one another and have equal stroke always.This is particularly suitable for being divided into equal two sections Zigzag type stair.That is, when the passenger-in-elevator arrived belly board 3, the walker on the adjacent segment stair was just in time in place at this, and when passenger-in-elevator's arrival floor platform, two walkers all arrive at the contiguous floors platform simultaneously, can use for next passenger-in-elevator is convenient.

Obviously, if be under the situation of straight movement type stair rather than Zigzag type stair between the contiguous floors, a walker can only be installed, then cable means is provided with to such an extent that meeting is simpler.

Two segment length in the Zigzag type stair not simultaneously, then cable means is provided with can slightly more complicated a bit.For example, each walker can set up a cable loop respectively, and is drawn by the elevator roller of different-diameter respectively.

The above-mentioned cable layout of walking about cable only is a schematic example, and in fact, those of ordinary skill in the art can design the various cable loops of walking.

To those skilled in the art, it is evident that this motor reducer mechanism is provided with an automatic stopping device when outage, this automatic locking function also can be himself inner structure characteristics generation, as turbine and worm decelerator.

In addition, single person elevator of the present invention also should comprise a controller 40, by it controlling motor reducer mechanism 30 normal startup, stop and rotating and emergency braking.Walker 10 is provided with some hand switches or push button pad 41, and the latter and controller 40 are set up to write to each other it is implemented control.

Best, from walker 10, stretch out an arm-rest frame 12 straight up, it is hand steered that its shape is convenient to the passenger-in-elevator.Preferably previous manual switch or push button pad 41 are installed on the arm-rest frame 12, so that the passenger-in-elevator goes operation after holding up the jail consciously.

In the embodiment shown in fig. 1, handrail 12 and carrying platform 11 both sides of guardrail 2 that are placed in.They also can all be arranged on the side of guardrail towards stair certainly.

Best, corresponding to two end point of travel of walker 10 on trapped orbit, two travel switch (not shown)s can be set respectively, or block and the travel switch (not shown) is set on walker.The signal that travel switch produced delivered to stop motor reducer mechanism 30 in the controller 40.

Be the elevator roller of another embodiment of the present invention as shown in Figure 3.But elevator roller 3 direct connections and are used for elevator cable 21 on the output shaft of aforesaid motor reducer 30.Concrete going up says that elevator roller 3 has a longitudinal axis, a face of cylinder 3 " and the conical surface 3 that continues at two ends, the described face of cylinder along this axis ' with 3 , the latter outwards is tapered along described axis.

Along described axis the described conical surface 3 ' and 3 and the face of cylinder 3 " on make substantially continuous zigzag shape flange 33 and/or groove 34.At elevator roller 3 along A to when rotation, along groove 34 walkings, promptly cable is received rope along B and C direction to cable simultaneously under the guiding of spiral fashion flange 33, promptly this elevator roller 3 has the effect of fall line and reason rope concurrently.

What is more important, when motor reducer and walker start since cable from the conical surface 3 ' thin footpath end to wide diameter end and face of cylinder elevator, thereby walker is from the low speed gentle acceleration.Arrive and be wound on the face of cylinder 3 at cable " time, walker is smooth running at a relatively high speed then.Cable from the wide diameter end of the conical surface 3 when thin footpath end is reeled, then walker slows down gradually until stopping at last.Thereby walker and on passenger and motor reducer starting and stop phase is subjected to inertia impact and greatly reduces.Make to drive more comfortablely, and prolonged service life of elevator.

Be the elevator trapped orbit of further embodiment of this invention as shown in Figure 4, wherein, be parallel to trapped orbit 15 and also further be provided with a movable rail 16, walker is rolled be connected on the movable rail 16 also being provided with another idler wheel mechanism (not shown) on the walker 11.Be in operation, movable rail 16 is placed on the stair terrace, with trapped orbit 15 common rolling bearings walker and on load, thereby it is more steady that walker is advanced.So just needn't come the supporting walking frame by guardrail.Thus, the walker operation is safer.

And, vertically stretching out two swivel arms 17 respectively from the two ends of movable rail 16 to trapped orbit 15, the latter is connecting trapped orbit 15 with revolute pair 18 or other articulated forms.When not using walker 11, movable rail 16, swivel arm 17 and walker 11 can be rotated about 90 ° and be fitted near the guardrail around trapped orbit 15.Just do not influence the normal current of stair this moment substantially.

Because trapped orbit and movable rail all are directly to paste to be placed on the stair terrace, thus not high to its strength and stiffness requirement, so the single person elevator system can be done light compactness.

Best, trapped orbit and movable rail all adopt metal tube to make.Be convenient to the assembling of single person elevator system on the one hand, on the other hand, can prevent the pedestrian that damages again.

Be the induction installation that stops of yet another embodiment of the invention as shown in Figure 5, wherein do the sliding bearing face of two guide holes 12 and so at its direction of travel of walker 11 upper edges, two guide rods 13 are passed in guiding therein, fix two cross bars 14 respectively in the latter's opposite end, thereby constitute a rectangular frame.This rectangle rack is connecting the contact (not shown) of a switching device.When rectangle rack runs into a predetermined barrier force, just make this contact action, stop motor reducer mechanism by aforesaid controller again.Thereby just can prevent that walker from crushing pedestrian or passenger.

Certainly, between this rectangle rack and traveling gear, also should be provided with a retracing spring (not shown).After obstacle or barrier force eliminating, this retracing spring automatically resets with regard to making rectangle rack and coupled contact.After this just can restart walker continues to rise or descend.

Be the residual breaking mechanism of anti-cable that the present invention also has an embodiment as shown in Figure 6.On walker 11 by a hinge a 28 ' lever 25 is rotatably mounted on the walker.Is set cable 21 at lever 25 away from an end of guardrail, and between this lever and walker 11, " be connected a spring 26; lever is pivoted to a direction, and the application force of spring makes lever pivot to another opposite sense under the effect of cable traction power F by another hinge 28.

Concrete going up say, and be residual when disconnected at cable, and lever 25 just rotates counterclockwise the orientation that is approximately perpendicular to the walker service direction under the effect of the bias force of spring 26, and lever 25 stretches out maximum and inserts between the railing 24 of guardrail to guardrail from the near-end of guardrail.Lever 25, hinge 28 ' and be fixed on the fulcrum 27 of walker ' and the guardrail synergy under, just prevented that walker 11 is with respect to the sliding of guardrail and stair, shown in the solid line among the figure downwards.Guarantee personal device security thus.

And under cable 21 normal tractive force effects, 25 on lever overcomes the bias force of spring 26 and cw pivots, making the near-end of lever 25 be separated from the interference of guardrail railing and apical grafting another and is fixed on fulcrum 27 on the walker 11 "; thus upwards operation of walker drawn, shown in the dotted line among the figure.

Also have, comprise control circuit even programmable processor of a complexity in the foregoing controller 40.But this can be manufactured out by those of ordinary skill in the art, moves needed controllable function thereby reach elevator.

Obviously, replacing a cable or a part wherein with chain also is a kind of feasible embodiment.

Be to be noted that modification or modification that those of ordinary skill in the art carries out on the basis of the foregoing description at last, all within the protection domain of present patent application.
