Definitions

  • the present invention discloses a compact step body in Die-cast aluminum with tread, step front and side struts with guide rollers, the special requirements for a higher Breaking load limit met.
  • Step body is made of longitudinal and cross members, front plate and Footplate assembled. Guide and idlers are included screwed their pedestals to the side members.
  • JP 01197298 discloses a step body with longitudinal and Cross beams on the lightweight beams for reinforcement purposes made of aluminum below the step plate and inside the Front panel to be attached.
  • For attaching these carriers has the step body from the footprint of tread and Front plate protruding counterparts with threaded holes, which counterparts or threads already during the manufacture of the Step carrier attached or cut.
  • the invention is characterized inter alia by characterized in that as The starting product is an existing compact stage in unchanged form is used, at which points Reinforcement elements for additional longitudinal and transverse reinforcement be attached.
  • the reinforcement elements per step are a bevel profile and each a side plate with a surrounding edge, which on the Compact stage to be screwed on at points to be reinforced.
  • the reinforcing elements are non-positively on surfaces of screwed existing ribs and webs of the compact step.
  • Step body 1 denotes a step body, which in the Today's usual way is made in die-cast aluminum. With 2nd are the idlers and 3 the driver bearings. The Carrier rollers 2 are fastened to kingpin 21. The behind the driver bearings 3, the step body 1 in this view laterally protruding parts are sliding guide shoes 18.
  • the Step body 1 also has an underside 16 with a middle, longitudinal reinforcing rib 5.2 and on both Sides of the reinforcing rib 5.2 each with a certain distance further, parallel reinforcing rib 5.1.
  • a rear transverse rib 4 extends over the entire underside 16, is greatly increased in the middle part and flows into the on both sides Basis of the driver bearings 3. Adjacent to the transverse rib 4 and the bottom 16 is a stiffening profile 6 inserted and the Side struts are enclosed with side plates 7 and 8. At 12 is the tread visible in this figure only as an edge designated.
  • Fig.2 is essentially the type of attachment Reinforcing elements can be seen.
  • the one Side strut 15 enclosing side plate 8 is with the Side strut 15 firmly connected with through screws 14 and an edge of its side surface also lies on the underside 16 of the Step body 1.
  • the stiffening profile 6 is with screws 13 attached to the transverse rib 4 and lies on the transverse rib 4 with a bent back and on the bottom with his Footprint full.
  • the rear of the stiffening profile 6 points to increase the section modulus at its upper edge another bend inwards.
  • the stiffening profile 6 also has a second curved wall on the front side so that its cross-section is roughly a U-profile represents asymmetrical cross section. So before fixing of the stiffening profile 6 no milling work on the step body 1 must be made points the bottom of the Stiffening profile 6 in those places where above Casting spigot 10 on the underside 16 of the step body 1 is present are corresponding recesses 19 on. Continuous recesses 9 on the stiffening profile 6 also bridge the longitudinal ones Reinforcing ribs 5.1 and 5.2, so that their shape and Function can be left. With this arrangement and Execution of the stiffening profile 6 increases the desired Resilience of the step body 1 at its rear part of the Tread surface 12 reached.
  • Figure 3 is the contour of the side plates, here the Side plate 7, can be seen. It lies with its front edge the rear 17 of the step front 11 and with its upper edge the underside 16 of the step body 1. A three-sided Enclosure of the side strut 15 and the inside of the Step body 1 adjacent edges of the side plate 7 result in the desired reinforcement of the side part of the step body 1.
  • Figure 4 shows another important one in the previous ones Figures invisible structural detail of the side panels 7 and 8 using the example of the side plate 8.
  • the assembly of the reinforcing elements 6, 7 and 8 is so far easy than all the holes for screwing with the Step body 1 pre-punched in the reinforcing elements 6, 7 and 8 are.
  • the reinforcing elements 6, 7 and 8 serve as Drilling gauges when drilling the through and threaded holes in the Step body 1.
  • the stiffening profile 6 only has to be inserted and drilled with the cross rib 4.
  • the side plates 7 and 8 are with the welded metal ring 20 on the respective Knuckle 21 placed and then screwed in until it the bottom 16 of the tread 12 and on the rear 17 of the Step front 11 are present. This is followed by drilling the Side plates 7 and 8 with the side strut 15 and screwing or riveting with the same.
  • the screw connections can be made by using joint filling adhesive between the contact surfaces get supported.
  • the stiffening profile 6 With further folding shapes and material thicknesses of the stiffening profile 6, its section modulus can be varied within wide limits.
  • the folding geometry and the contour of the side surface are given by the type of use.
  • a variation of the load capacity can be achieved within certain limits with the choice of the material and its thickness.
