Description

The present invention relates to agriculture and, in particular, can be used in horticulture, in garden and summer cottages, as well as during emergency work near poles of electric and telephone communications.
The problem of falling and severely injuring fruit pickers from trees when using traditional stairs with transverse bars is known.
A well-known ladder designed to collect fruit from tall trees, containing three racks made with through holes connected in the upper part by a hinge assembly, and the flexible rungs missing in the holes of the racks and fixed in the nodes by the nodes, pairwise connecting the racks around the perimeter. The hinge assembly is made in the form of an axis on which two stands are mounted rotatably in parallel planes, and an earring rigidly connected to the end of the axis of the earring, to which the third rack is pivotally connected with the possibility of rotation in a plane perpendicular to the rotation planes of the remaining racks. In this case, the first and second racks are made with elongated sections in the upper part, see RU 2247209, Е06С 1/383.
A staircase is also known, which contains two parallel racks, to which they are attached at an angle of ninety degrees, equally spaced and parallel steps, on the lower side of which a safety element is fixed, for example a synthetic cord, cable or chain, see RU 2592272, E04F 11/00 from 16.06. 2015.
However, the known staircase does not provide a stable position when collecting fruits from trees. Since the upper step of the ladder leans against the trunk of the tree and comes into contact with it at only one point. In this case, the user, at the slightest deviation to the side, creates a sliding step of the stairs along the tree trunk, which leads to the fall of the stairs and injuring the user.
The aim of the creation of the present invention is to achieve a technical result to ensure the safety of the user when operating the stairs when collecting fruits from trees.
The specified technical result is achieved by the fact that in the known staircase containing the crossbars located at an angle of 90 ° to the support posts, which in the upper part are carried out reduced to each other by a distance equal to the diameter of the fruit tree trunk, while the two upper crossbars are made in the form of ribbons made of velcro fabric, and the lower ends of the support posts are made pointed.
The specified technical result is illustrated by graphic materials. In FIG. 1 is an image of a staircase.
The ladder for collecting fruit from trees includes:
1. support racks;
2. steps;
3. ribbons made of velcro fabric;
4. The pointed lower ends of the support legs.
The staircase consists of steps 2 located at an angle of 90 ° to the support posts 1, which are made pointed at the lower ends 4, inclined to the upper ends and in the upper part brought to each other by a distance equal to the diameter of the fruit tree trunk. The two upper supporting steps 2 are made in the form of ribbons 3 made of velcro fabric.
With the stairs, work as follows.
The user near the fruit tree sticks the ladder with the sharp lower ends of the support posts 1 into the ground and leans against its trunk its upper ends so that the two upper ribbons made of velcro fabric 3 cover the tree trunk. The upper tape 3 covers the barrel at an angle of more than 180 °, and the lower tape 3 - at an angle of about 90 °. The roughness of the velcro fabric and tree trunk provides a strong grip of the ladder with the trunk. In case of a dangerous movement of the user to the side, reaching for the fruit at a dangerous distance, the ladder will not shift to the side, but only turn around the trunk by 3-4 cm. This will be a signal for the user to return to their previous position.
Thus, the claimed invention ensures the achievement of the technical result - the safety of the user during operation of the stairs.
The claimed design of the stairs can be used with poles of electric and telephone communications during urgent emergency and restoration work.
The claimed invention is new, previously unknown, which indicates its compliance with the patentability criterion - novelty.
The staircase can be executed in the conditions of a carpentry workshop, which indicates its compliance with the patentability criterion - industrial applicability.
