Description

The innovation relates to a step ladder according to the preamble of claim 1. Step ladders of this type are known in a wide variety of designs. These ladders are used to perform work at heights. For safety reasons, the aim is generally to make the steps as large as possible. However, the design of existing step ladders limits this aim, which has led to the development of step-enlarging devices that, as separate components, can be optionally and subsequently attached to the steps. For example, in the brochure of the company Munk, Günzburger Steigtechnik, one finds such devices as the "MaxxStep step module," which can be placed on the rungs of ladders. The brochure also mentions the "clip-step relax" step pad, which is equipped with padding, and the "clip-step R13" step pad, which has slip-resistant properties. Furthermore, the brochure mentions the "R13 hook-on platform" and the "R13 hook-on step," which can be attached to the steps. The step module and the tread pads only slightly increase the tread surface of the steps, while the hook-in platform and the hook-in step guarantee large tread surfaces, but are only intended for a single step of a step ladder and must be removed when folding the step ladders. Hailo is known for a step ladder that also consists of a ladder section and a ladder support section. To meet safety requirements, the steps of this step ladder are particularly large. This is made possible because each step is mounted on the ladder section and can move around its own horizontal axis, and a sliding joint mechanism is used to which each step is connected. When this step ladder is folded, the steps pivot upwards around their respective horizontal axes using the sliding joint. When the step ladder is unfolded, the steps pivot back into their working position together. Based on the described state of the art, the task of the innovation is to further develop a step ladder of the type mentioned at the beginning in such a way that the tread surface of all steps belonging to a step ladder can be enlarged even more than is currently possible with the state of the art. The solution to the problem is described in the characterizing part of claim 1. The decisive advantage of the proposed solution lies in the fact that when the stepladder is folded into its non-use position, a portion of each step is accommodated by the previously unused space between the second set of stiles. This, in turn, significantly increases the surface area of each step. Larger treads not only provide the user with greater stability while working, but also reduce stress on the knees and ankles, thus preventing joint damage, which can be particularly noticeable with age. The previously unavoidable need to constantly adjust the body's position on the relatively narrow steps to achieve sufficient stability is reduced. The proposed solution allows the steps to be extended considerably towards the ladder's support element, resulting in a significant increase in the surface area of each step. The front section of each step can either be tapered towards the opposite ladder support element, i.e., becoming progressively narrower, or the front section of each step can be narrower than the rest of the step. The innovation is explained in more detail using two examples. It shows 1 Side view of an unfolded stepladder in its working position; 2 in top view and section the folded step ladder according to 1 in non-use position as well as 3 also shown in top view is another contour of the front section of a step. 1 Figure 1 shows a side view of an unfolded stepladder 1, which is thus in its operating position. The stepladder 1 comprises a ladder element 2 and a ladder support element 6. The ladder support element 6 is movably connected to the ladder element 2 about a horizontal axis 10 by means of two bearings 9. The ladder element 2 has two first stiles 3, which are fixedly connected to each other by steps 4. The ladder support element 6 has two second stiles 7, which are also fixedly connected to each other by at least two connecting means 8. At least one locking means is provided, which ensures that the stepladder 1 can only be opened to a predetermined angle. The step ladder 1 can be folded out at a limited angle to assume its operating position. Each step 4 has a front section 5, and each front section 5 faces the opposite ladder support element 6. In the operating position of the step ladder 1, each step 4 is arranged horizontally. Steps 4 are known in a wide variety of embodiments. They can also be combined with known rungs that connect the stiles 3. The step ladder 1 described so far is representative of all other and differently designed step ladders 1 and corresponds to the prior art. 2 shows in a top view and in sectional view the in 1 The step ladder 1 is described. The step ladder 1 is folded and thus in its unused position. The first two stiles 3 of the ladder element 2 are shown. Between the first two stiles 3 is a step 4, which
