Abstract
The invention discloses a herringbone ladder. The herringbone ladder comprises a main ladder and a supporting ladder, wherein one end of the main ladder is hinged to one end of the supporting ladder; the main ladder comprises two parallel vertical side plates and a plurality of steps connected between the side plates; the supporting ladder comprises two parallel vertical side plates, a top step and a first step; and the top step and the first step are respectively arranged at the upper ends and the lower ends of the side plates. The herringbone ladder is characterized in that a piece of rectangular wear-resistant cloth is arranged between the side plates of the supporting ladder; and the upper end and the lower end of the wear-resistant cloth are respectively fixed on the top step and the first step. Compared with the prior art, the herringbone ladder disclosed by the invention can be used for high-altitude operation, a worker can sit or lie on the herringbone ladder to have a rest in leisure time, the angle of the herringbone ladder can be adjusted until the worker feels comfortable when having a rest, and the herringbone ladder is simple and practical.
Description
Technical field
The present invention relates to five metals and manufacture field, particularly relate to a kind of double ladder.
Background technology
In the life of daily house or outdoor study, the take object of eminence of people all needs to use double ladder, conventional double ladder is by two width one end hinges ladder together and be connected to can the strut of doubling form between two width ladders, and the length of this strut determines the maximum angle that can open of double ladder.Conventional double ladder is general only for high-rise working, and function ratio is more single.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art with not enough, a kind of simple and practical double ladder is provided.
The present invention is achieved by the following technical solutions: a kind of aluminium double ladder, comprise one end hinge main ladder of a width together and a width supporting ladder, described main ladder comprises the side plate of two pieces of erected parallel and the multiple step be connected between the side plates, described supporting ladder comprises the side plate of two pieces of erected parallel and is separately positioned on top pedal and the first order pedal at the upper and lower two ends of side plate, it is characterized in that: the canvas or other the wear-resistant fabric that are provided with one piece of rectangle between the side plate of described supporting ladder, the two ends up and down of described wear-resistant fabric are separately fixed on described top pedal and first order pedal, this wear-resistant fabric can be seated for operating personnel's idle or recumbency is had a rest.
Further, between described main ladder and the side plate of described supporting ladder, be connected with spacing band, be provided with buckle in the middle of described spacing band and make this spacing strip length adjustable, the maximum opening angle of this spacing band described main ladder of restriction and supporting ladder.
Further, the side plate bottom of described main ladder and described supporting ladder is equipped with non-slipping block, to strengthen the frictional force of ladder and ground.
In order to the present invention can be understood more clearly, illustrate below with reference to accompanying drawing and set forth preferably embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the stereogram of double ladder of the present invention.
Fig. 2 is the structural representation of spacing band in Fig. 1.
Detailed description of the invention
Please refer to the stereogram that Fig. 1 and Fig. 2, Fig. 1 are double ladders of the present invention, Fig. 2 is the structural representation of spacing band in Fig. 1.The double ladder of this aluminium comprises one end hinge width main terraced 10 together and a width supporting ladder 20.Described main terraced 10 comprise the side plate of two pieces of erected parallel and the multiple step be connected between the side plates.Described supporting ladder 20 comprises the side plate of two pieces of erected parallel and is separately positioned on top pedal 22 and the first order pedal 24 at the upper and lower two ends of side plate.Be connected with spacing band 30 between described main terraced 10 and the side plate of described supporting ladder 20, be provided with buckle in the middle of described spacing band 30 and make this spacing band 30 adjustable length, described main terraced 10 and the side plate bottom of described supporting ladder 20 be equipped with non-slipping block 40.
Be provided with the wear-resistant fabric 29 of one piece of rectangle between the side plate of described supporting ladder 20, the two ends up and down of described wear-resistant fabric 29 are separately fixed on described top pedal 22 and first order pedal 24.In the present embodiment, described wear-resistant fabric 29 is canvas.
Compared to prior art, double ladder of the present invention both can be used for high-rise working, can be seated again or recumbency is had a rest for operating personnel's idle, and the length that only need adjust spacing band 30 just can by stance adjustment during people's rest to comfortable angle, simple and practical.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
