Definitions

  • the invention relates to a step attachment attachment for step or ladder and in particular a step attachment tip adapted for attachment to circular or round section posts.
  • FR 1 530 108 discloses a terminal claw for fixing degrees to the two uprights of a household ladder.
  • the claw is attached to the upright by a cylindrical depression in which a peg is formed cooperating with a hole formed in the upright, and by a cylindrical protruding portion also and having a hole cooperating with a rivet for fixing the claw to the tubular body of the amount, and its lower side has a hole for the passage of a fixing screw of the wooden degree with the claw.
  • La fixing the claw to the amount is made according to two attachment points, one on a projecting portion and this fixation is relatively complex.
  • FR 1 530 108 discloses a scale according to the preamble of the claim of claim 1.
  • FR 2 100 520 Also known from FR 2 100 520 a metal ladder whose steps are fixed to the uprights by means of end caps nested in the steps and fixed to the uprights each according to at least two attachment points, rivet or lugs conferring the transverse rigidity of the link.
  • the invention aims to simplify this tip and in particular its attachment to the stud without protruding part or several attachment points and proposes a step fixing attachment for step or ladder according to claim 1.
  • the rod can be tightened crimped on the upright or tightened by means of a nut (threaded rod).
  • the step generally comes from extrusion, profiled at great length and cut to length, it can receive the tip without further processing, deburring for example, as is necessary in the current technique.
  • the maintenance of walking by the tip on its periphery and likewise the tip on the surface, the inner side of the upright provide a large range of the elements relative to each other and thus a high-strength connection of walking on the amount.
  • a left endpiece and a straight endpiece will be symmetrical to each other with respect to a vertical median plane of the steps of the step or ladder, these ends anchoring at each end of the fixed step and applying on each of the amounts of the step plan.
  • the inner cutout of the tip is semicircular and extends over half of the support post of circular section. In this way, there is continuity of material between the cutting edge and the corresponding amount without risk of snagging clothes of the user.
  • a collar piece may possibly be mounted in connection with the cutting edges of the endpiece around the upright, the stud connecting rod amounts can then be removed, replaced by a direct connection by screw or other to the end of the walk.
  • the cutout must correspond to meet the service inclination of the step plan, generally from 20 to 25 °, to a portion of cylinder inclined at this angle relative to the plane of the endpiece, which should normally be horizontal in use. .
  • the invention also relates to a step or a ladder comprising at least one upright equipped with step fixing ends according to the invention.
  • Figure 1 Due to the general symmetry of the steps or steps of a step or ladder relative to a median vertical plane of the step or ladder, and the analogy of the fixing of the steps of the to one another, there is shown in Figure 1 a single setting of a step to the amount of steps of a step.
  • FIG. 1 shows a left-hand fixation, the right-hand fixation being obtained by symmetry by relative to the median vertical plane of the foot market (not shown) and the same for the other steps.
  • This walking plan 1 of the step comprises two identical amounts 3 of circular section and steps 5 fixed regularly on these amounts.
  • the steps are connected to the uprights by means of an intermediate piece, namely the step-fixing end-piece 7 according to the invention, arranged between the step, its end, and the corresponding amount.
  • This part is preferably made from a casting of light metal alloy, for example aluminum. It has a generally flattened body 9 of flattened sleeve, of rectangular cross-section, adapted to the profile of the received step 5. The body is thus open towards the rear thus allowing the introduction of the step by its end, which is complementary rectangular section with low clearance of the inner section of the sleeve.
  • a cylindrical cutout 11 is formed in a centered position on the front face of the body.
  • This cut is in fact that of a half-cylinder of circular cross section whose axis is inclined relative to the plane of the sleeve.
  • the angle of inclination is approximately 20 to 25 °, corresponding to the inclination of the step plane in the operating position of the step, the steps as the plane of the tip then being in substantially horizontal position.
  • This cutout 11 is in fact complementary to the upright according to a half portion thereof as shown in Figures 1 and 3, so that the amount can be received in this cutout, on this half portion, very low peripheral clearance.
  • a drilling hole 13 provided for the passage of the rod 15 connecting the step to the amount.
  • This rod 15 besides it serves as a support for walking by a suitable longitudinal cradle housing, allows to rigidly connect the two opposite amounts of the step plan to walk.
  • the edge 17 of the lateral faces of the body is chamfered and slightly rounded at the front corners.
  • the inner section of the sleeve is preferably slightly dimmed inside (slightly conical) so that the end of the step can be stuck without play inside the sleeve.
  • step 5 after extrusion, profiled lightweight metal alloy, aluminum in particular, is cut to the desired length of center distance between the uprights with a straight edge 19 without further treatment, including deburring and chamfering as for conventional connections by welding steps on rectangular section uprights.
  • the two end pieces 7 are then each slid on each of the ends of the fixed step and pressed back into the press until a length of about 10 mm abutting the cut.
  • the rod 15 is threaded into the set of steps and end caps, protruding on each side a little more than the diameter of the uprights.
