Description
Technical field
The invention belongs to technical field of furniture, more particularly, to a kind of assembly type chair ladder.
Background technology
Ladder is widely used as the instrument ascended a height.In family, in order to change light fixture etc., in the feelings without ladder
Under condition, the mode that can only be superimposed with multiple stooles is so abnormally dangerous.
The content of the invention
In order to solve the above problems, the purpose of the present invention is to disclose a kind of assembly type chair ladder, and it can both realize stool
Function, can be used as stool ladder high again, and it is realized using following technical scheme.
A kind of assembly type chair ladder, it include the first chair leg, the second chair leg, the 3rd chair leg, the 4th chair leg, the first cross bar,
Second cross bar, chair plate, backrest, the first chair leg, the second chair leg, the 3rd chair leg, the 4th chair leg is parallel and is separated from each other setting, and first
Cross bar is arranged between the first chair leg and the 3rd chair leg, and the second cross bar is arranged between the second chair leg and the 4th chair leg, the first chair
Leg is located at rear end left side, and the second chair leg is located at rear end right side, and the 3rd chair leg is located at front end left side, and it is right that the 4th chair leg is located at front end
Side；Backrest can be arranged on the front side on the first chair leg and the second chair leg top；It is characterized in that first chair leg and the second chair leg
All it is made up of backrest section and chair leg part, backrest section front side forms after slightly being contracted than chair leg part front side and holds chair plate plane, chair
Plate can be placed in upper surface, the upper surface of the 4th chair leg, the appearance chair plate plane of the first chair leg, the appearance of the second chair leg of the 3rd chair leg
In chair plate plane；The upper surface of the 3rd chair leg, the upper surface of the 4th chair leg, the first chair leg hold chair plate plane, the second chair leg
Hold chair plate plane to be in same plane；The first terraced leg, the 3rd terraced leg are sequentially installed with to the right from the upper end right side of the 3rd chair leg,
First terraced leg, the 3rd terraced leg are movably connected in the upper end right side of the 3rd chair leg by the first active connection, and the first terraced leg can phase
Make forward and backward rotation for the 3rd chair leg, the 3rd terraced leg can make forward and backward rotation relative to the 3rd chair leg；From the upper end of the 4th chair leg
Left side is sequentially installed with the second terraced leg, the 4th terraced leg to the left, and the second terraced leg, the 4th terraced leg pass through the activity of the second active connection even
It is connected on the upper end left side of the 4th chair leg, the second terraced leg can make forward and backward rotation relative to the 4th chair leg, the 4th terraced leg can be relative to the
Four chair legs make forward and backward rotation；It is installed with gangboard between first terraced leg, the second terraced leg, upper gangboard is from the first terraced leg, second
Terraced leg starts to extend to the first chair leg, the second chair leg direction；Lower gangboard is installed between 3rd terraced leg, the 4th terraced leg, under
Gangboard extends since the 3rd terraced leg, the 4th terraced leg to the 3rd chair leg, the 4th chair leg direction；First terraced leg is connected with the 3rd chair leg
The upper surface at place is plane, and with the upper surface of the 3rd chair leg in the same plane, the other end of the first terraced leg is inclined plane；The
Two terraced legs are planes with the upper surface of the 4th chair leg junction, and with the upper surface of the 4th chair leg in the same plane, the 4th is terraced
The other end of leg is inclined plane；3rd terraced leg is plane with the upper surface of the first terraced leg junction, and with the upper table of the first ladder leg
In the same plane, the other end of the 3rd terraced leg is inclined plane in face；4th terraced leg is flat with the upper surface of the second terraced leg junction
Face, and with the upper surface of the second terraced leg in the same plane, the other end of the 4th terraced leg is inclined plane；The other end of the first terraced leg
Inclined plane, the inclined plane of the other end of the second terraced leg incline direction it is consistent；Inclined plane, the 4th of the other end of the 3rd terraced leg
The incline direction of the inclined plane of the other end of terraced leg is consistent；The incline direction of the first terraced leg other end and the 3rd ladder leg other end
Incline direction is opposite.
Principle of the invention is such：When being used as chair, the first terraced leg, the second terraced leg, the 3rd terraced leg, the 4th
Terraced leg, upper gangboard, lower gangboard are all located at chair plate lower section and without departing from four lines of chair leg bottom outer most edge；Chair plate is placed
The upper surface of the 3rd chair leg, the upper surface of the 4th chair leg, the appearance chair plate plane of the first chair leg, the appearance chair plate planar shaped of the second chair leg
Into plane top；By backrest against the first chair leg, the front side of the second chair leg and most patch chair plate upper surface, you can with as normal
Chair use.
When being used as ladder, chair plate and backrest are removed, by the first terraced leg, the first terraced leg to the first chair leg, the second chair
The upper extreme direction of leg rotates through the first chair leg, the front side surface of the second chair leg, after chair plate is put, then backrest is placed on chair plate
And it is close to the first chair leg, the front side surface of the second chair leg, the first terraced leg, the first terraced leg are leaned against and the upper of ladder is completed on backrest
Part frame；The 3rd terraced leg, the 4th terraced leg are rotated through into the 3rd chair leg, the to the lower extreme direction of the 3rd chair leg, the 4th chair leg again
The front side surface of four chair legs simultaneously supports the lower part frame for completing ladder, so far completes the framework of ladder, therefore, this
Assembly type chair ladder in application can both be used as chair, it is also possible to used as ladder, saved input funds, expanded
Purposes, using more convenient, safer.
Certainly, in order to preferably implement, upper gangboard can be also fixedly mounted between the first terraced leg, the second terraced leg, upper gangboard
Extend to the 3rd chair leg, the 4th chair leg direction since the first terraced leg, the second terraced leg.
Certainly, in order to preferably implement, upper gangboard can be also fixedly mounted between the first terraced leg, the second terraced leg, upper gangboard
Can also be since the first terraced leg, the second terraced leg to the 3rd chair leg, the 4th chair leg direction and the first chair leg, the second chair leg direction both sides
Extend.
Certainly, in order to preferably implement, lower gangboard can be also fixedly mounted between the 3rd terraced leg, the 4th terraced leg, lower gangboard
Extend to the first chair leg, the second chair leg direction since the 3rd terraced leg, the 4th terraced leg；
Certainly, in order to preferably implement, lower gangboard can be also fixedly mounted between the 3rd terraced leg, the 4th terraced leg, lower gangboard
Extend to the first chair leg, the second chair leg direction since the 3rd terraced leg, the 4th terraced leg and since the 3rd terraced leg, the 4th terraced leg to
3rd chair leg, the 4th chair leg direction extend simultaneously.
As long as the setting of upper and lower gangboard can not rotated when can meet rotation because of collision.
Certainly, upper and lower gangboard can also be a lath, that is, go up gangboard and be arranged between the first chair leg, the second chair leg；Under
Gangboard is arranged between the 3rd chair leg, the 4th chair leg.
Certainly, a kind of assembly type chair ladder described above, it is characterised in that the front end of the chair plate can be that centre has
Breach, i.e., the fore-end of chair plate can only cover the upper end of the 3rd chair leg and the 4th chair leg, so be more easy to implement.
Certainly, a kind of assembly type chair ladder described above, it is characterised in that each building block is all timber or plastics
Or steel or alloy or its combination.
Therefore, can be used as chair since the present invention has, can be used as ladder again, save input funds,
Purposes is wide, uses the main beneficial effect such as more convenient, safer.
