Definitions

  • the invention refers to a rung for a swimming pool ladder.
  • rungs for this application which basically consist of a metal plate with a general section of an inverted U which is fixed at each end to the ladder beams through the two headpieces which are attached, on one of their sides, to the corresponding plate ends and which, on the opposite side, are attached to the profile of the respective ladder beams.
  • the applicant firm is titleholder of the Utility Model ES 288.641 which refers to a rung of this class in which the attachment between the metal plate, headpiece and ladder beam by means of nut and bolt is carried out by a fin at the end of the metal plate with a die-cut slot, this fin being bent towards the inside of the rung is applied against the inner side of the headpiece, the bolt being threaded through orifices in the tubular beam, through a bore hole in the headpiece and through the orifice in said fin, against which the nut is screwed down to the bolt.
  • the objective of this invention is to improve these methods of attachment by carrying out the aforementioned die cut-outs in smaller sizes to avoid weakening the end sections of the rung composition, and to include a sturdy linking element to reinforce this attachment.
  • a block has been designed as a basic linking element between the metal plate, the end headpiece, and the corresponding ladder beam, which is inserted in each of the slots at the end of the metal plate and which has a head which rests on the rim of said slots.
  • This block presents an orifice which when attaching the block to the metal plate is aligned with the orifices in the headpiece and corresponding ladder beam, the block, headpiece and beam being fixed in position with the nut and bolt.
  • the slots at each end of the metal plate are obtained by means of a partial die cut-out which leaves a small flange, which is bent 90° towards the inner section of the rung and is thus positioned between the aforementioned block and the inner side of the corresponding ladder beam.
  • the rung includes a metal plate 1 in a flattened and inverted U section, forming an upper surface 2 with a slight crosswise arch and lengthwise fins 3 with the edge formed by a curved recessed fold 4.
  • the two headpieces 5 are attached to the ends of this plate, these headpieces being formed of moulded one-piece sections which are fitted with a step 6 along the middle which determines the limit abutment of said attachment, the opposite side of said headpieces presenting a circular recess 7 for attachment to the corresponding metal and tubular ladder beams M.
  • This block presents an orifice 12 which coincides with the orifice 13 of the headpiece and with the orifices 14 of the ladder beam, through which orifices a bolt 15 is inserted, whose head 16 butts against the outer side of the ladder beam M, this bolt protruding through the block 9 where it is coupled to a spring washer 17 and the corresponding nut 18.
  • the slots 8 are obtained by partial die cut-outs leaving a flange 19 which is bent at 90o towards the interior of the rung and which contributes towards reinforcing the attachment being positioned between the block 9 and the inner side of the corresponding headpiece 5.
  • the contour of slots 8 present peripheral inset recesses 20 in which the aforementioned head is embedded.
  • the top surface 2 of the metal plate presents slightly protruding embossed ribs for slip-proof purposes.
