Abstract

This utility model relates to a stair step (A) located horizontally between two vertical profiles of metal stairs in different numbers, allowing the user to move vertically up and down in the vertical direction by stepping on it. In particular, a utility model relates to a structure that improves the strength of said stair step (A) with respect to vertical loads (FIG. 1).

Description

This utility model relates to a staircase located horizontally between two vertical profiles of metal stairs in different numbers, allowing the user to move vertically up and down in the vertical direction by stepping on it.

In particular, a utility model relates to a structure that improves the strength of said staircase with respect to vertical loads.

The prior art.

Today, staircases made of metal are known for use in enclosed spaces and open spaces. Said staircases consist of two vertical profiles and staircases located horizontally between two vertical profiles at certain intervals in different numbers depending on the length of the stairs, allowing the user to move vertically up and down in the vertical direction by stepping on them. When using ladders, the entire weight of the user falls on the horizontally located ladder step, on which the user steps.

One of the most important issues associated with metal stairs is the higher requirement for bearing capacity / crushing strength of the stairs. This issue is important both for the safety of the user and for the long life of the ladder.

In stairs manufactured in accordance with the prior art, steps are attached directly to the vertical load-bearing profiles with the edges of a portion of the main part, usually by welding, without any mounting protrusions / eyes. Moreover, in order to increase the strength on the side surfaces along the width of the steps, vertical ribs are formed.

In the staircases, in accordance with the prior art, as mentioned above, because of the lack of strength of the step and because of the load applied to it, deflections occur and the staircase becomes unusable over time. In order to eliminate these shortcomings and meet the need for a high-strength stair step, it became necessary to carry out development in the field of technology related to stair steps.

The purpose of this utility model.

The main objective of this utility model is to provide a structure that increases the strength with respect to the vertical loads of the stair step, located horizontally between two vertical profiles of metal stairs in different numbers, allowing the user to move vertically up and down in the vertical direction by stepping on it.

The purpose of this utility model is to enable the ladder steps to be attached to vertical supporting profiles by means of fixing eyes formed at the edges of the main part and located above the main part. Thus, the forces caused by horizontal loads falling on the main part of the step are distributed evenly over the step and vertical profile, while deflection is prevented.

Another objective of this utility model is to minimize deflection of the side surface of the staircase by forming horizontal ribs above and below the vertical edges (both edges) along the step on the side surfaces of the staircases. The specified structure is preferably formed in front of the steps (on the side on which the user climbs the stairs).

The structural and characteristic differences and all the advantages of this utility model will become clearer from the following detailed description with reference to the accompanying graphic materials and, therefore, the conclusion should be made, taking into account these figures and a detailed description.

Detailed description of the utility model.

In this detailed description, preferred embodiments of the stair step (A) according to the present utility model are described so as to provide a better understanding of the subject, and do not have a limiting effect.

The staircase step (A) according to the present utility model is first cut from a metal material in the form of a sheet of a certain thickness and then the staircase is shaped as a result of passing through the required processes. The specified stair step (A) also contains the main part (1), on which the user steps. At least one fixing eye (1.1) is formed on the upper edge sections of said main part (1) for fastening on vertical profiles forming a ladder. At least one fixing hole (1.4) is also formed at the bottom of said main part (1) for fastening on vertical profiles forming a ladder. The ladder step (A) according to the present utility model is attached to vertical supporting profiles by means of at least one fixing eye (1.1) from the upper part and at least one fixing hole (1.4) from the lower part (Fig. 1).

In the staircase step (A) according to the present utility model, at least one vertical rib (1.3) is formed with defined gaps on the side surface of the front of the staircase (on the side on which the user climbs the staircase). Along the width of the step, at least two horizontal ribs (1.2) are formed on the upper and lower parts of the vertical rib (1.3) so as to hold the specified vertical rib (1.3) between them in order to minimize the deflection of the side of the stair step (A). A number of horizontal ribs (1.2), preferably one (Fig. 1 and Fig. 2), are formed on the rear side of said staircase step (A).

Claims (3)

A stair step (A) located horizontally between two vertical profiles of metal stairs in different numbers according to the length of the stairs, allowing the user to move vertically up and down in the vertical direction by stepping on it and containing the main part (1), which the user steps on at least at least one mounting hole (1.4) at the bottom of the specified main part (1), formed for fastening on at least one vertical rib (1. 3) formed at certain intervals on the side surface of the front side of the stairs (on the side on which the user climbs the stairs), characterized in that the stair step (A) contains: at least two horizontal ribs (1.2) formed along the width of the main part (1) so that they are on the lower and upper sections of the specified vertical ribs (1.3); at least one fixing eye (1.1) formed to fasten the upper edge of the main part (1) to the vertical profile forming the ladder.
