Definitions

  • the present invention relates to a modular composable element for making stepladders in general.
  • the mentioned shelf-shaped central portion is provided,at one end whereof, with an upright portion or pin to be coupled to a sleeve portion provided at the other end of the shelf shaped central portion of a lower modular element.
  • the task of the present invention is that of overcoming the above mentioned drawbacks by providing such a modular composable element,for making stepladders in general,which affords the possibility of changing,depending on the contingent requirements, the pitch,mutual slanting of the steps, as well as the useful width of said steps.
  • Another object of the present invention is to provide such a modular composable element for making stepladders in general which,owing to its constructional features,is able of providing a great reliability and safety of use.
  • Yet another object of the present invention is to provide such a modular composable element for making stepladders in general which may be easily made starting from easily available elements and materials and which,moreover,is of a comparatively reduced cost.
  • a modular composable element for making stepladders in general,comprising an elongated body,supporting a plate-like element and provided with a central portion to be coupled,at one end whereof, with an upright portion,engageable with an adjoining lower modular element and defining,at the other end whereof,a sleeve element to be engaged with the upright portion of an adjoining upper modular element, characterized in that it comprises moreover means for locating said upright portion, with respect to the central portion,which may be displaced perpendicularly to the upright portion and may be movably locked in position,in order to vary the width of the step.
  • the modular composable element for making stepladders in general comprises an elongated body, indicated overally by the reference number l,which consists of a central portion 2 defining,at one end whereof,a sleeve element 3.
  • the mentioned elongated body 2 is practically made starting from a U-bent sheet metal portion, provided with an edge portion pair 4 defining said central portion 2 and a portion circumpherentially extending and defining the sleeve element 3.
  • the mentioned central portion engages with an upright portion 7,downwardly extending.
  • the edge portions 4 of the central portion 2 are provided at the top with wings 10, advantageously of triangular shape,which lie in a substantially horizontal plane and which act as a supporting element for a plate-like element 11.
  • a main feature of the invention is that the mentioned central portion 2 is coupled with the upright portion 7,downwardly extending,with a possibility of being displaced along a substantially perpendicular direction to the upright portion 7 itself.
  • locating means in order to obtain the mentioned coupling, there are provided locating means,advantageously consisting of a slot pair 12,longitudinally extending on the central portion 2.
  • annular recesses 30 arranged at the holes 14.
  • the slots 12 will have their edges 12a inwardly bent with a shape fitting the shape of the annular recesses 30.
  • fixing brackets indicated at 20 which are provided with a fixing wing 21 and a coupling wing 22,engageable with the mentioned upright portion 7.
  • the above disclosed modular composable element affords the possibility of changing,between a step and the other,both the mutual slanting and the pitch or elevation, as in the conventional steps,and moreover it affords the possibility of varying the useful width, since the upright portions can be fixed at different positions with respect to the central portion 2.
  • a modular composable element for making stepladders in general which is construction-wise very simple and,being of U-shape,it provides,by its edge portions 4, a clamping means engaging firmly with the upright elements, both at the bottom and at the top,thereby providing the stepladder with a great stability.
