Abstract
A kind of electric expansion stair of Armrest, comprise motor, winding belt wheel, wire rope, Compress Spring, broadstep, collapsible riser and handrail guardrail, described winding belt wheel is connected to the side of motor, described wire rope is connected between winding belt wheel and Compress Spring, described Compress Spring is arranged between broadstep and collapsible riser, described handrail guardrail is arranged on broadstep top, when flexible stair fold, tighten up wire rope by described motor, described handrail guardrail is in drawing shape in; During flexible stair folding and expanding, described motor reversal unclamps wire rope, and described broadstep and collapsible riser launch under Compress Spring effect, and described handrail guardrail is with broadstep synchronous expansion.The present invention, can by this stair folded concealed on loft top time no in the restricted situation of the interior space, can Automatic-expanding in the needs used time, facilitates personnel upper and lower.
Description
Technical field
The present invention relates to the field of stair, particularly relate to a kind of electric expansion stair of Armrest, be applicable to residential usage.
Background technology
Often can with loft in commercial and residential building top layer house, conveniently upper and lower loft, needs build fixing stair or adopt folding stair; fixing stair need to take certain residence space; folding stair sets up loft openings position in use, and used time carrying is not covered up, not too convenient.
A kind of loft of popular employing stretches stair gradually in recent years, this stair are a kind of collapsible stair, be fixedly mounted on loft openings position, folding storage is on loft platform at ordinary times, under collecting state, do not destroy room top structure and outward appearance, when needing to use, manually or automatically mode stretcher is located at permanent position, very convenient, therefore this kind of flexible stairway art is ripe and form series of products, there are many manufacturers produce customizations both at home and abroad, but due to the restriction in structure and space, this kind of flexible stair do not possess handrail function, therefore there is inconvenient and certain potential safety hazard during personnel's stair activity.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of electric expansion stair of Armrest, in the restricted situation of the interior space, can by this stair folded concealed on loft top time no, and can Automatic-expanding in the needs used time, facilitate personnel upper and lower.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the electric expansion stair providing a kind of Armrest, comprise motor, winding belt wheel, wire rope, Compress Spring, broadstep, collapsible riser and handrail guardrail, described winding belt wheel is connected to the side of motor, described wire rope is connected between winding belt wheel and Compress Spring, described Compress Spring is arranged between broadstep and collapsible riser, described handrail guardrail is arranged on broadstep top, when flexible stair fold, wire rope is tightened up by described motor, described handrail guardrail is in drawing shape in, during flexible stair folding and expanding, described motor reversal unclamps wire rope, and described broadstep and collapsible riser launch under Compress Spring effect, and described handrail guardrail is with broadstep synchronous expansion.
In a preferred embodiment of the present invention, described handrail guardrail comprises fence upright and rope form handrail, and described rope form handrail is connected to the top of fence upright.
In a preferred embodiment of the present invention, described fence upright is rigid posts.
In a preferred embodiment of the present invention, described rope form handrail is Free software state when shrinking stair and being folding.
In a preferred embodiment of the present invention, described rope form handrail is tensioned state when shrinking stair and launching.
The invention has the beneficial effects as follows: the electric expansion stair of Armrest of the present invention, in the restricted situation of the interior space, can by this stair folded concealed on loft top time no, can Automatic-expanding in the needs used time, facilitate personnel upper and lower, simultaneously, on the telescopic basis of stair, add the design of hand rail, both remained the collapsible hiding advantage of flexible stair, take into account again safety and convenient consideration.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Structural representation when Fig. 1 is the expansion of electric expansion stair one preferred embodiment of Armrest of the present invention;
Structural representation when Fig. 2 is the electric expansion stair of Armrest in Fig. 1 folding;
Being labeled as in accompanying drawing: 1, motor, 2, winding belt wheel, 3, wire rope, 4, Compress Spring, 5, broadstep, 6, collapsible riser, 7, handrail guardrail, 71, fence upright, 72, rope form handrail.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
A kind of electric expansion stair of Armrest, comprise motor 1, winding belt wheel 2, wire rope 3, Compress Spring 4, broadstep 5, collapsible riser 6 and handrail guardrail 7, described winding belt wheel 2 is connected to the side of motor 1, described wire rope 3 is connected between winding belt wheel 2 and Compress Spring 4, described Compress Spring 4 is arranged between broadstep 5 and collapsible riser 6, and described handrail guardrail 7 is arranged on broadstep 5 top.When flexible stair fold, tighten up wire rope 3 by described motor 1, described handrail guardrail 7 is in drawing shape in; During flexible stair folding and expanding, wire rope 3 is unclamped in described motor 1 reversion, and described broadstep 5 and collapsible riser 6 launch under Compress Spring 4 acts on, and described handrail guardrail 7 is with broadstep synchronous expansion.
Further, in order to stair activity safe ready, described handrail guardrail 7 comprises fence upright 71 and rope form handrail 72, and described fence upright 71 is rigid posts, and described rope form handrail 72 is connected to the top of fence upright 71.
Wherein, described rope form handrail is Free software state when shrinking stair and being folding, does not take up room; Described rope form handrail is tensioned state when shrinking stair and launching, and can bear certain pressure, the safety of protection stair activity personnel.
