The specific embodiment

For example the utility model is done description in more detail below in conjunction with accompanying drawing:

In conjunction with Fig. 1～3, the hanging and tracting type staircase mainly comprises the seat hitch and drives the trailer coupling two large divisions that it is mainly formed has: Collapsible seat 1, following movable V-arrangement wheel 2, seat suspension plate 3; Rhombus track 4, on support V-arrangement wheel 6, V-arrangement wheel gusset piece 7, joint coupling 8, on draw V-arrangement wheel 9; Rail supported plate 10, traction gusset piece 11, driver gear 12, guiding tooth bar 13; Drive motor 14, following traction V-arrangement wheel 15, movable stay bearing plate 16, regulating spring 17.Described seat hitch mainly comprises: Collapsible seat 1, seat suspension plate 3, on support V-arrangement wheel 6, following movable V-arrangement is taken turns 2 primary members such as grade.Wherein going up support V-arrangement wheel 6 rolls on rhombus track 4 through the driving action of trailer coupling; The guiding and the positioning action that cooperate with rhombus track 4 through V-shaped groove; Drive Collapsible seat 1 motion; The down movable V-arrangement wheel 2 main regulating actions of being responsible for make no matter Collapsible seat 1 is in the process of going upstairs, and the horizontal motion after still turning round all can make Collapsible seat 1 keep straight down; Described driving trailer coupling mainly comprises: on draw V-arrangement wheel 9, following traction V-arrangement takes turns 15, the tooth bar 13 that leads, driver gear 12, main portions such as drive motor 14.Under the effect of drive motor 14; Through the engagement of driver gear 12 with guiding tooth bar 13, drive whole trailer coupling motion, upper and lower V-arrangement wheel 9,15 is responsible for clamping rhombus track 4; Make whole trailer coupling relative pose with rhombus track 4 in motion process constant; Through coupling mechanism, just can drive the motion of seat suspended portion, realize function upstairs.

Whole hanging and tracting type seat is realized installing through rail supported plate 10 and staircase boards 5; And be configured in a side near banister; So that in the process of going upstairs, do not influence other residents' normal discrepancy, and the collapsible design of seat 1 employing, under obsolete situation; Can its folding placement be reduced taking of space.Rhombus track 4 is installed on the stay bearing plate, and all the other basic structures all are that carrier is installed with the track, and in operational process with track generation relative motion; Its main operational process is: when control signal excites drive motor 14 work; Gear 12 promptly begins and guiding tooth bar 13 engaged transmission, drives trailer coupling and brings into operation, under the combined action of V-arrangement wheel gusset piece 7 and jointed coupling 8; Trailer coupling is promptly realized traction function; Drag the operation of seat hitch, the support V-arrangement wheel 6 of going up of seat hitch cooperatively interacts with rhombus track 4, guarantees guiding and the location of staircase in operational process.

In conjunction with Fig. 1, Fig. 2 does specific descriptions to the characteristics of the utility model two kinds of different running statees during last going downstairs.Running state for going upstairs under the staircase shown in Figure 1 can clearly be observed from figure, and in the last operational process of going downstairs, track is in heeling condition in the space, but seat 1 requirement must be in vertical state.Used the elastic damping technology in order to overcome this technical barrier at this; I.e. flexible adjustment effect through down movable V-arrangement wheel realizes that seat suspension plate 3 is in vertical state constantly; Concrete control process is following: if seat suspension plate 3 with respect to the deflection of vertical state generation certain angle, then will certainly produce gravitational moment under the common action of gravity of seat suspension plate 3 and seat 1; Make it that trend that returns to vertical state arranged; Therefore designed movable V-arrangement wheel 2 and adapted to mechanism with the adjustable supports plate 16 common gravity of forming, promptly under the effect of gravity countermoment, movable V-arrangement wheel 2 can be along with seat suspension plate 3 deflects; It is that relative V track 4 inclined degrees take place to slide and move down that movable V-arrangement is taken turns; Along with movable stay bearing plate 16 common compression springs, realize the vertical deflection of seat suspension plate 3, make it return to vertical state and keep the level of seat.After turning,, still require the seat will the maintenance level along with rhombus track 4 gets into the level run states; This control process is basic identical with above-mentioned control process; Do in the whole service process of staircase, seat suspension plate 3 always is in straight down with the gravity direction of seat 1, therefore; Still regulate after getting into horizontality according to above-mentioned principle, and the level of assurance seat.

The hanging and tracting type staircase gets into the level run state by tilting to go up downstairs movement state; Owing to will turn over the right angle in a space; The tractive force direction variation of staircase in the state transformation process just also is a space right-angle, in order to overcome the technical barrier that turns over space right-angle, the degree of freedom of two spatial rotational of traction coupling mechanism of this patent; Form with jointed coupling 8 by V-arrangement wheel gusset piece 7, in the turning process, can well adapt to the variation of space right-angle.

The key model of hanging and tracting type staircase is with the mountain cable car is similar excessively; Because the action of gravity of suspended portion; Will certainly in the vertical direction and the strong point of last support V-arrangement wheel 6 produce moment, in order well to overcome this moment, in this patent design, the people is sitting in as far as possible on the seat center-of-gravity position with on support V-arrangement wheel 6 fulcrum be on the same straight line; The capsizing moment of gravity generation just greatly reduces like this, realizes the better more stable manned function of upward going downstairs.

Go up resident downstairs and call out staircase through the elevator control button, staircase can arrive automatically and call out the position, and the resident takes after the seat; Select the floor that to arrive through the controller on the seat; Control signal drives the motor of trailer coupling, and trailer coupling promptly can affect the operation of seat hitch, and the movable V-arrangement through hitch in operational process is taken turns the automatically regulating that can realize seat; Be in the attitude of stair activity stage or level run stage power seat according to elevator; The horizontality that always keeps seat is unlikely in operational process, the people to be dropped, and makes operation more stable.
