Abstract
The utility model relates to a two-purpose stable folding ladder with a side ladder frame for a treading seat. The side of a main ladder frame is provided with a side stop shaft which is connected with the side ladder frame which is connected with the main ladder frame by a pull rope. The upper end of the main ladder frame is provided with a soft chair back, a treading seat board and a folding handle. When the utility model is stored, the side ladder frame is combined with the main ladder frame by the side stop shaft to cause the total width of the utility model to approximate to the total width of a common ladder. When the utility model is used, the main ladder frame is firstly unfolded, the side ladder frame automatically unfolds toward both sides of the main ladder frame by being pulled by the pull rope to enlarge the width of the utility model to obtain the goal of increasing the lateral stability of the utility model. When the utility model is unfolded, the treading seat board automatically places horizontally, working personnel can pull up the folding handle for standing and the working personnel can also back on the soft chair back and sit on the treading seat board to work.
Description
Affiliated technical field
The utility model relates to a kind of truck work device, especially can allow the safer ladder of work high above the ground.
Background technology
At present, known folded ladder is by the composition of proportions of height much larger than width.Be " people " font after ladder opened and place, the people can be pedaled from a side of " people " font ladder.But, because the height of these folded ladder make the stable higher of " people " font expansion direction, and its lateral stability is lower, causes difficulty to the user, occurs down terraced casualty accident easily much larger than width.
Summary of the invention
In order to overcome the deficiency of existing ladder medio-lateral instability, the utility model provides an a kind of dual-purpose stable folded ladder of stepping on the side ladder, and this folded ladder can not only make the ascending stair operation more firm, and can be used as high-altitude chair use easily.
The technical scheme that its technical problem that solves the utility model adopts is: in the main ladder support side side limit shaft is arranged, the latter connects the side ladder, and the side ladder links to each other with main ladder support by stay cord, and there is the soft chair back main ladder support upper end, steps on seat board and stow-away arm rest.When depositing, the side ladder merges by side limit shaft and main ladder support, makes the overall width of ladder close with common ladder.During use, launch main ladder support earlier, then launch side ladder both sides from the trend main ladder support under the pulling of stay cord, and the width of ladder is strengthened, and reaches the purpose that increases the ladder lateral stability.Ladder is stepped on seat board when launching and is set level automatically, and the staff can be with the stow-away arm rest pull-up for the use of standing, and also can lean against the flexible chair back and be sitting in to step on the seat board and work.
The beneficial effects of the utility model are, can stand easily or sitting work when increasing the ladder lateral stability, and are simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is main view principle figure of the present utility model.
Fig. 2 is a side-looking schematic diagram of the present utility model.
Fig. 3 is a D structure schematic diagram of the present utility model.
1. stow-away arm rests among the figure, the 2. flexible chair back, 3. main ladder support is 4. stepped on seat board, and 5. bar is 6. stepped in the stow-away arm rest position, 7. side limit shaft, 8. stay cord, 9. side ladder.
The specific embodiment
In main ladder support (3) side side limit shaft (7) is arranged, the latter connects side ladder (9), and side ladder (9) links to each other with main ladder support (3) by stay cord (8), and there is the soft chair back (2) main ladder support (3) upper end, steps on seat board (4) and stow-away arm rest (1).When depositing, side ladder (9) merges by side limit shaft (7) and main ladder support (3), and stow-away arm rest (1) is folded to main ladder support (3) and goes up folding position (5) and locate, and makes the overall width of ladder, height close with common ladder.During use, launch main ladder support (3) earlier, then launch side ladder (9) both sides from trend main ladder support (3) under the pulling of stay cord (8), qualification position to side limit shaft (7) stops, at this moment the lower end of the lower end of main ladder support (3) and side ladder (9) is on the plane, the width of ladder is strengthened, reach the purpose that increases the ladder lateral stability.Step on seat board (4) when ladder launches and set level automatically, it is bigger than common ladder to step on seat board (4) area, and the staff can also can lean against the flexible chair back (2) and be sitting in the upward work of seat board (4) of stepping on stow-away arm rest (1) pull-up for the use of standing.
Claims (2)
- One kind with the side ladder step on the seat a dual-purpose stable folded ladder, it is characterized in that: in the main ladder support side side limit shaft is arranged, the latter connects the side ladder, and the side ladder links to each other with main ladder support by stay cord.
- 2. band side ladder according to claim 1 step on the dual-purpose stable folded ladder of seat, it is characterized in that: there is the soft chair back main ladder support upper end, steps on seat board and stow-away arm rest.
