Definitions
- the invention relates to a folding step according to the preamble of claim 1 Such folding step can be found in DE-U-83 34 841.7.
- the construction of the handlebars ("linkage") provided for connecting the two steps is such that the handlebars in necessary adaptation to them Attachment either on one side or on the other side of the steps - different must be carried out. This means correspondingly increased manufacturing costs.
- the guide slot runs in the handlebars as an abutment for the upper one Step serving rod with a certain, relatively small distance from the connecting line of the two articulation points of a handlebar on the side facing away from the riser of the folding step Side of this connecting line in the handlebars.
- This can be achieved that the articulation points between the upper step and the two handlebars in the space between them angled extension of the step and the side of the extension facing this extension Holmes of the support leg lie. This has the safety of use and a pleasing Advantages serving the exterior of the folding step.
- the present invention has for its object the manufacturing effort for the handlebars Reduce folding step; Furthermore, it should be achieved that the handlebars in the area of the articulation points no more unsightly grinding marks on the angled extensions of the steps as a result of opening and closing the folding step arise or are obvious.
- the invention is according to the characterizing part of claim 1 proposed.
- the handlebar construction according to the invention enables the handlebar - while maintaining it
- the advantages that come with the fact that the guide slot in the handlebar for the as an abutment for the upper step serving staff with a certain, relatively small distance from the Connection line of the two articulation points of the handlebar on the ascending leg of the folding step opposite side of this connecting line runs in the handlebar - both on one and on the other side of the steps can be applied, and also the problem of mentioned unsightly grinding marks is eliminated.
- handlebars of this type can also be used for three-stage or multi-stage folding steps or ladders.
- a folding step 1 which consists essentially of a riser 2, a on the riser 2 articulated support leg 3 and between the riser and support leg 2 or 3rd arranged steps 4 and 5 and Lenkem 6 there.
- the treads 4, 5 are on the articulation points 7-10 with the handlebars 6 (the drawing only shows one of the two links connecting the steps 4, 5) articulated, e.g. by means of rivet-like connecting means.
- the articulation points 7-10 form the corners of one Parallelogram.
- the upper step 4 is assigned an abutment in the form of a rod 11, which in the two Spars of the support leg 3 is attached and on which the guide slot 12 of the Handlebar 6 leads. - The step 4 is supported by a downward angled extension 4a off the rod 11.
- a further guide slot 14 is provided in the handlebar.
- the guide slot 14 additionally provided in the handlebar 6 in addition to the guide slot 12 allows the use of similar handlebars for both sides of steps 4, 5 of the Folding step 1, wherein the mentioned raised areas 15 and 16 on the respective one Extension 4a or 5a of step 4 or 5 are in contact. This way it becomes an inexpensive one Production of the handlebars reached.
- the links 6 are expediently made of flat material, e.g. made of sheet steel, the mentioned raised areas 15, 16 are formed by stamping or the like.
