Abstract
The utility model relates to a single-ladder-armrest ladder. According to the single-ladder-armrest ladder, a single ladder armrest is designed; two ends of each step are bent upwards, and the steps are fixedly arranged on the ladder armrest at equal intervals and are vertical to the ladder armrest; a ladder foot is fixedly arranged at the lower end of the ladder armrest; the open distance between two feet of the ladder foot is greater than the length of each step to increase the stability of the ladder; and a ladder leaning part is fixedly arranged at the upper end of the ladder armrest. When the ladder leans against a wall, people can carry out climbing operation by stepping on the steps; and the single ladder armrest is used by the ladder, the length of the steps can be shortened, so that the aims of material conservation, small size, light weight and easiness in moving are achieved.
Description
Technical field
The utility model relates to a kind of ascending tool, and is especially simple, economize that material, volume are little, terraced staircase of lightweight list.
Background technology
At present, known ladder is held up with step by the double joint ladder and is consisted of, and ladder provides convenience for people's ascend operation.But ladder commonly used now is owing to being that the double joint ladder is held up, result be many with material, volume large, Heavy Weight and cause and be difficult for moving, and institute takes up space large when idle.
The utility model content
Hold up because of the double joint ladder and cause, Heavy Weight many with material, the large deficiency that takes up space in order to overcome now ladder, the utility model provides a kind of list terraced staircase, this ladder not only economize material, volume little, lightweight, easily move, and institute takes up space little when idle.
The technical scheme that its technical problem that solves the utility model adopts is: whole by ladder hold up, step, foot of ladder and ladder be by consisting of.Ladder hold up be designed to single, be arranged on the centre position, step two ends upwards bend up, and the equidistant ladder that is fixedly mounted on is held up, and hold up vertical with ladder, step is held up the equal in length of both sides at ladder, and foot of ladder is designed to down " Y " font, is fixedly mounted on the lower end that ladder is held up, the distance that two pin of foot of ladder open is greater than the length of step, to increase stability, ladder is fixedly mounted on by being designed to " Y " font the upper end that ladder is held up.Should the ladder rested against the wall, people just can step on the step ascend operation, hold up because this ladder has only used single ladder, and step length can shorten, and therefore, has reached and has economized the purpose that material, volume are little, lightweight, easily move.
The beneficial effects of the utility model are, economize material, volume is little, lightweight, only ladder is held up be designed to single, simple in structure.
