Abstract
The utility model discloses a dual-purpose staircase which comprises a main body. Step structures are uniformly distributed on the main body. The dual-purpose staircase is characterized in that: the main body is divided into a fixing part and a turning part along the extending direction; a baffle is arranged at the outer side of the turning part, a rotating shaft which is vertical to the baffle is respectively arranged at the center position in an inclined plane at the bottom part of each step structure on the turning part, one end of each rotating shaft near the baffle is connected with a chain wheel transmission mechanism after running through the baffle, and sliding way parts are covered on the inclined planes at the bottom parts of the step structures; a positioning structure is respectively arranged between the side face of each step structure and the baffle, so as to form the conversion positioning of obverse and reverse working faces of the turning part. The main body of the dual-purpose staircase is composed of the fixing part and the turning part, and the chain wheel transmission mechanisms drive the rotating shafts in the turning part to rotate, so that the turning part can be turned to form a sliding way, steps and the sliding way can exist at the same time, the walking up and down is safer, and the utilization is more convenient as well as flexible.
Description
Technical field
The utility model relates to a kind of stair, is specifically related to a kind ofly can make the dual-purpose stair that stair also can be made slide.
Background technology
Stair are indispensable facilities in the multi-storey building building, stair mainly contain cement step stair at present, wooden step stair, or metal step stair or the like, but no matter the sort of stair, all be that ladder type is step-like, because the limitation of the existence of its structure itself, on, when going downstairs, the pedestrian can only get on or get off step by step, this is fully passable for the normal people of health, but for the action inconvenient people of lower limb, they use wheelchair to ride instead of walk, so just can't going up or down stairway, even the normal person, when they in tow during the article of luggage truck or case and bag and so on, also effort comparatively up and down on the stair of this step.
At above-mentioned deficiency, some improvement have appearred.Modal is the slideway that inclination is set in a side of stair, the gradient of slideway is identical with stair, and wheelchair can pass through from slideway like this, and stair activity becomes possibility, carry the pedestrian of luggage truck or case and bag, also can compare the labour-saving stair activity by this slideway.The stair of this class formation are in some public arenas; more as railway terminal, subway station etc.; but; side at stair is provided with slideway structure; usually the width of slideway must reach and can hold wheelchair width up and down; need the occupation space area just to become bigger like this; and the probability that slideway uses is compared much lower with step; in the bigger place of visitors flowrate,, cause stream of people's speed of travel slow easily if only current from step; thereby it is current from slideway to have the pedestrian; crowding mutually between the crowd very easily causes the accident, and has potential safety hazard.
Summary of the invention
The utility model purpose provides a kind of dual-purpose stair, by the improvement to structure, ladder and slideway are existed simultaneously, and it is safer to walk up and down, and uses more convenient, flexible.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dual-purpose stair, comprise a body, be evenly equipped with ledge structure on the described body, described body is along being divided into fixed part and upset portion on the bearing of trend, the outside of turning part is provided with baffle plate, center, inclined-plane, in the upset portion each described ledge structure bottom is provided with an axis of rotation perpendicular to baffle plate, the nearly baffle plate end of each described axis of rotation runs through baffle plate and is connected with a chain wheel driving mechanism, and described ledge structure bottom is coated with slideway portion on the inclined-plane; Set bit architecture between each described ledge structure side and described baffle plate, form the conversion location of positive and negative two work planes in turning part.
Above, be divided into fixed part and upset portion on the body, the outside of upset portion is provided with baffle plate, center, inclined-plane, in the upset portion each described ledge structure bottom is provided with an axis of rotation perpendicular to baffle plate, the nearly baffle plate end of each described axis of rotation runs through baffle plate, be connected with the chain wheel driving mechanism in the baffle plate, described chain wheel driving mechanism can adopt prior art, comprise driving chain, sprocket wheel and motor, drive driving chain by motor and drive sprocket rotation, the rotation forward or backwards of motor makes upset portion along with rotation, realizes positive and negative two work planes (step state and slideway state).Under the step state, the ledge structure of upset portion is positioned at the outside, and is consistent with fixed part, forms stair step by step; Upset portion is the slideway state after rotating 180 degree, and the slideway portion under this state is positioned at the outside, and each slideway portion is connected level and smooth inclined-plane of formation mutually, and is current for wheelchair or go-cart etc.The location of two duties is realized that by location structure this location structure can be provided with the latch that cooperates with locating hole and finish by in the ledge structure side locating hole being set on described baffle plate.
In the technique scheme, described location structure is, has a locating hole on each described ledge structure, is that symmetrical centre is arranged with a pair of spacing latch that cooperates with this locating hole with described axis of rotation on the described baffle plate.In the axis of rotation both sides spacing latch is set, two duties of the corresponding upset of difference portion, when upset portion rotates, spacing latch is for extracting state, after turning over turnback, the spacing latch of corresponding locating hole position inserts in the locating hole, realizes the location between upset portion and the baffle plate, steady-working state.
Another kind of technical scheme is, the cross section of described ledge structure is an isosceles right triangle, the height and the width that are ledge structure equate, under this structure described location structure can for, each described ledge structure is positioned at place, inclined-plane, described bottom, be that symmetrical centre is provided with a pair of locating hole with described axis of rotation, the baffle plate at corresponding locating hole place is provided with a pair of spacing latch.Since locating hole with the same hypotenuse of axis of rotation on and be the symmetrical centre setting with the axis of rotation, rotate just in time switch of both sides, 180 degree back locating hole, again by the insertion of a pair of spacing latch, lock the duty of upset portion.
Further technical scheme, described spacing latch is spacing latch of electromagnetism or the spacing latch of spring.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the body owing to the utility model stair is made of fixed part and upset portion, the intracardiac axis of rotation that is provided with in the inclined-plane, ledge structure bottom in the upset portion, axis of rotation runs through baffle plate and is connected with a chain wheel driving mechanism, make that upset portion can be that turnback is turned in rotating shaft with the axis of rotation, form respectively with the step state of fixed part unanimity and with fixed part different slideway state, make ladder and slideway to exist simultaneously, and do not take greater room, the conversion work state improves utilization of space when needed;
2, ladder and slideway can exist simultaneously in the utility model, make to walk up and down safelyr, use also more convenient, flexible;
3, the utility model is simple in structure, and is easy to operate, is fit to promote the use of.
