Abstract

This is an adjustable stairs. The main principle of design is: The stair steps are connected by special joint, this joint is composed with inner sheath joint and inner sheath joint and outer sheath join. Between them there are inner screw thread and outer screw thread. They can adjust the horizontal distance between two stair steps; they are fixed by screw bolt. At the same time, they can make the stair steps to form fan structure, to satisfy the demand of returning stair. Between the upper base plate and lower base plate there are screw rod and inner outer sheath and their screw thread, they can adjust the vertical distance between two stair steps.

Description

Adjustable stair

Technical field

The present invention relates to the architectural decoration field, is a kind of adjustable stair.

Background technology

At present, the ZL patent No. 01270415.6 of notice of authorization, disclosed " improving the stair tread of structure and the combination of handrail " to society, the advantage of this combined structure is easy to assembly, be easy to produce in batches, its weak point be the platform layer with the level interval of platform layer vertical height, adjacent stations layer from being difficult for adjusting.After stair assembling typing, the easy people of resident family, the difference of health status, the execution of but can not achieving one's goal of height, the mutual width of intending changing the ladder layer.

Summary of the invention

The present invention is directed to above-mentioned deficiency, will provide a kind of adjustable stair, to solve stair platform layer and platform layer vertical height, adjacent stations layer level interval from nonadjustable problem to this area.And the problem that need carry out the rotation of certain limit angle because of the difference of building structure.Now in conjunction with the accompanying drawings, its feature is described as follows: a kind of adjustable stair, these stair are made of handrail, vertical rod, cross bar, floor, adapter sleeve, gangboard, upper substrate, screw rod, infrabasal plate etc., it is characterized in that:

A) cover 8-1 and is connected overcoat 8-2 in the adapter sleeve 8 that connected of floor 4 is provided with and connects, the external screw thread of cover is connected with the internal thread that is connected overcoat in promptly connecting, and is located by the set bolt 6 of connection overcoat; When loosening circle decide bolt, turn connection overcoat will move as horizontal direction between upper substrate 10 and the adjacent upper substrate.

B) be connected with swivel nut at the middle part of infrabasal plate 12, be connected with screw rod 11 at the middle part of upper substrate 10, screw rod is threaded among the swivel nut 12-1;

C) overcoat 7 of upper substrate 12 connections is provided with internal thread, and the interior cover 5 that infrabasal plate 12 connects is provided with external screw thread, and regulates fixing by screw rod 11.When loosening screw rod 11, turn overcoat, will move as vertical direction between upper substrate 10 and the infrabasal plate 12.

Handrail 1 is double end circular arc column, and the surface is provided with annular lines or does not establish toroid, is connected with ball 14 around the corner, and their middle part is installed with round steel 13, in the two ends of round steel screw thread is arranged, and pieces together tight by nut 15.This handrail integral body is S-shaped, and the turning must be established more when floor is higher, is then finished the variation of its connection angle by ball.

The ball that is connected between handrail will be made as bead shape.

Long stair will be set up support column 16 in the middle, to strengthen the bearing strength of stair.

Be provided with inner prop 17, check lock lever 18, latch segment 19 in the support column 16, the inner prop external diameter is close to the internal diameter of column jacket 16-1, and the check lock lever 18 that latch segment 19 middle parts connect extends to column jacket, and latch segment 19 is cone-shaped, is provided with stupefied 20 on cone.When the check lock lever that extends to column jacket upwards pulled out, the diametric plane of cone promptly blocked the internal diameter port of inner prop, made column jacket and inner prop be in arrested state, stupefied in addition the anti-effect that radially slides.The locking rod end locking of extending the most at last, support bar has just been located, and this structure is regulated the check lock lever of front-wheel just as the handle-bar middle part.

The shape of gangboard 9 is made as:

A) the concave-convex gangboard 21;

B) the swallow-tail form gangboard 24;

C) bent arc gangboard 25;

D) the zigzag gangboard 26;

E) length splicing gangboard 27;

F) anti-slide board 28;

G) the strip sketch plate 29.

To set up upholstery border or not adorn upholstery border in the end of above-mentioned seven kinds of gangboards, select one with the difference hobby custom that adapts to the client.

Handrail 1 is connected by curved handrail 31 in the corner, and the external diameter that is provided with widely-pitched at middle screw rod 34 is connected with nut 33 with the internal thread that is provided with narrow pitch and is connected with small screw 32; Twist when widely-pitched and still to have small gap when motionless, then tighten and fill up small gap, to increase good looking appearance by small screw.Being threaded between handrail 1 and handrail 1 by the joint 30 that is provided with internal thread and round steel 13 terminations.

It is clamping cross bar in two selected stainless steel strips of vertical rod that vertical rod 2 is connected with cross bar 3, and in these stove bolt of being set up between the two 37 middle punches 36, is screwed by primary nut 38.

This adjustable stair are easy to large batch of specialized production, can stair be combined into spiral stairs at any angle according to the different structure in house.With hobby, the custom that adapts to different crowd, be convenient to regulate the distance of platform layer height and adjacent stations interlayer, be provided with anti-gliding style floor again.A gangboard structure great variety of models has been enriched the buyer's market in this field, promise well.
