Definitions

  • the invention relates to the extra step board for the ladder with the task of relieving pain in the legs, to ensure safety in the workplace and the reduction of injury.
  • the invention belongs to the E-range, that is to construction, subclass E 06C ladder, to the group E 06 C 7 / 00- assemblable parts or tools and to the subgroup E 06 C 7/08 - running boards.
  • rung ladders horizontal rungs between the bars.
  • step ladder horizontal rungs
  • the legs tire when climbing and standing slower.
  • the sprouts point upwards with the narrow side, then the soles of the feet lean against a narrower part. This creates the problem of standing safely on the ladder. In this area of the sole of the foot, you feel greater pain, with the leg joints and leg muscles tiring faster. In this case, the burden on the spine becomes even stronger and thus the probability of injury larger.
  • the technical problem solved by this invention relates to the ease of climbing and standing on the ladder with the rungs facing upwards (rung ladders). It shows how to increase the area of the rungs in such a case so that the foot can stand safely and on a larger surface.
  • the gist of the invention is the additional footboard for the ladder which is attached to the rungs.
  • the extra step board includes: a platform, two sliders with the gripping jaw and two screws to attach the footboard to the bars.
  • the platform has a square tube shape.
  • the gliders are inserted into the platform opening. This has on the side surfaces, the openings with the locks to control the extraction of the sliders and determine.
  • the platform surface can have different designs. It can either have elongated or transverse elevations against slipping. You can also apply a different layer of material against slipping.
  • the gliders have a body and a gripping jaw.
  • the gliders are pulled into the platform with the body, with the gripping pines they are attached to the spars of the ladder.
  • a channel for the movement of the locks was executed.
  • Through the jaw leads an opening with the thread for the screw.
  • the gripping jaw is attached to the ladder spar.
  • the gliders are retracted into the platform, as long as the gripping jaws do not frame the spars and are not fastened with the screws to the spars.
  • the relievebrett according to this invention has a much wider area to stand, than the surface of the rungs.
  • the ladder accessory treadboard includes: a platform A, slider B, and screws C.
  • the platform A figs. 1, 2, 3, and 4 has a body 1.
  • the body has a square tube shape with an internal opening 3 in which the gliders go in. Through the side surface, threaded openings have been made through which go through the screws 4 to limit the extraction of the slider from the platform.
  • the platform surface may be smooth or rough against slipping. It can be done in three ways: with elongated grooves; with elongated transverse grooves or with a layer of material that has a good frictional resistance.
  • Figures 5 and 6 show an example of platform A with elongated grooves 2 against slipping-from above and from the perspective.
  • the glider B The glider B
  • the slider B, pictures 7, 8, 9, 10 and 11 consists of a body 5 and the gripping jaw 6. Between the gripping jaw is a passage 7 for the ladder stiles.
  • the Greifkieferinnencons 8 are parallel oblique to better adhere to the ladder stile.
  • a gripping jaw side extends an opening 9 with the thread for the screw, with which the slider is attached to the ladder rung.
  • an elongated channel 10 was incorporated on one side surface of the slider. Through this channel, the screw 4 moves as a barrier against the withdrawal of the slider from the platform.
  • the screw C, pictures 16 and 17, serves to fix the additional step board to the bars 15 of the ladder D.
  • the screw head has a larger circumference to facilitate turning when tightened.
  • a loose, straight plate 13 was attached, which has a slightly larger circumference than the screw body. Thus, one allows one better leaning against the spars. It also prevents the spars are damaged, Figure 16.
  • the screw is tightened through the opening 9 of the gripping jaw 6 of the slider B.
  • the additional footboard with the gliders B in the platform A is shown -from the top and from the front, in partial cross-section.
  • the additional footboard, pictures 16 and 17, is assembled before use: the screws 4 on the platform A are turned up so far; that you can push the slider B in the openings 3 from the two sides into the platform. On the sliders, the screws C are already pre-assembled for tightening. Thereafter, the screws 4 are tightened again until they go into the elongated channel 10 on the body of the slider 5. Thus, you can easily pull out the sliders. Before attaching the additional step board, the sliders are pulled out until the spars 15 fit exactly into the openings 7 of the gripping jaw 6. Then the gliders are fastened to the spars with the screws.
  • the additional footboard is ready, the feet can stand stable on it. If you want to transfer the additional footboard to another rung or another ladder, all you have to do is loosen the screws C and pull the sliders into the platform.
  • the additional footboard is suitable for wood, plastic and metal ladders, which can be used in industry, construction and private purposes. However, the prerequisite is that the sprouts point upwards with their narrow side on which they are standing.
  • the running boards can be made of different materials, especially light metal or hard plastic.
