Definitions

  • the invention relates to a ladder standing aid for a ladder, which two, by one Has numerous rungs connected spars, and on flat wall surfaces, as well is freely adjustable on inside corners, outside corners and on columns.
  • Freely adjustable ladders are used in practice with an optimal angle of attack of approx. 70 ° based on the walls of buildings.
  • the Spars of ladders are usually built slightly resilient, so small Bumps, or if floor and wall are not exactly two right-angled ones Form areas to be rebounded by ladder torsion. In practice, are desired
  • ideal conditions for hiring ladders are not always given. The user often makes dangerous compromises. He also climbs the ladder, for example, if only the more or less hard punctual engagement of a spar on the The wall.
  • EP-PS 0 598 874 and the corresponding WO94 / 29561 made in essential to increase the safety for ladder users appropriate accidents can be avoided as far as possible, furthermore the safe ones Extending the use of step ladders without having to work on ladders or complicate the use of ladders.
  • the mentioned publication proposes to improve the security of ladders by making them different directed, fixed contact surfaces can be arranged in a targeted manner.
  • the two spar ends with forward-facing contact surfaces for flat wall surfaces inside facing surfaces for outside corners and pillars facing outside Contact surfaces equipped for inside corners.
  • the contact surfaces are known per se Rubber buffers, e.g. formed for door hinges.
  • the second case geometrically due to an impeller only one punctiform or at most one linear Contact point.
  • the two proposed solutions are based on a common one Basic concept, namely the use of the top bar end for the Add a ladder head.
  • a so-called adapter is screwed on for each end of the spar.
  • the adapter is by itself by attaching rubber pins with appropriate contact surfaces already a ladder standing aid for straight wall surfaces.
  • the new invention was based on the task, a generic To improve ladder standing aid so that both a cost and a Weight saving is possible and that an appropriately equipped ladder as many situations as possible can be used with increased security.
  • the ladder standing aid according to the invention is characterized in that the Ladder standing aid can be quickly installed and mounted directly on a selectable rung removable clamping device and two spacers with peripheral Contact points from an outside corner area to an inside corner area of less than 90 ° each, so that there are two for any situation Appropriate investment sites can be used.
  • the new invention is based on two findings. On the one hand, it is logical a conductor head according to the cited prior art at the upper ends of the Attach ladder stiles, as this means the greatest possible force from the stiles direct, e.g. on a house facade. In contrast, it is one The fact that the maximum forces to be transmitted through the conductor head are only one Make up a fraction of the weight of a person climbing the ladder. The Rungs are sufficiently strong for the weight load by the person dimensioned so that the far lower forces of a rung attached ladder support are harmless. The vast majority inside and outside corners in buildings are 90 °. Compared to industrial Manufactured products, however, have a much greater tolerance or much more larger deviations.
  • the 90 ° mentioned are more of a theoretical quantity and can be remarkable on two systems chosen at random for the ladder placement differ.
  • a more selective investment site adapts much sooner than two Contact surfaces. This is even more true when the peripheral investment agencies both Cover an outside angle of less than 90 ° as for inside angles.
  • the new Solution thus enables in a substantially larger part of the practical given a situation, especially in inner or outer corners and even at acute angles.
  • the ladder standing aid can consist of two individual, opposite spacing brackets, which each have their own clamping device and two complementary Contact points.
  • the ladder standing aid preferably has only one yoke-shaped double bracket and only a single clamping device for the double bracket.
  • the second solution is currently preferred because both the manufacturing effort and the time required for Assembly / disassembly can be surprisingly reduced.
  • the ladder standing aid is Can be screwed to a rung within a few seconds and again when not needed removably.
  • One clamping device is in the middle of a rung arranged attacking and advantageously via a clamping rail with the Spacer bracket is fixed or detachably connected.
  • the one attacking in the middle of the rung Clamping device forms together with the clamping rail on the corresponding outer ends with respect to the rung a multi-point clamping. See you in practice, then it can be quickly established that almost all of them without exception Ladder brands a rung length or a free distance between the two Have spars of at least about 30 cm. In some countries there is one minimum rung length even prescribed. If the total length of the Clamping rail with the smallest possible distance between the two bars can be installed, the new ladder support can also be used with all wider ladders be used. Thus, the new ladder standing aid is just as universal for new ladders as well as for retrofitting according to the solution described at the beginning the state of the art. The new solution fits even more optimally correspondingly greater stability to concrete situations.
  • the clamping device has a clamping head.
  • the clamping head is in Use position thanks to an upside-down U-shape and the clamp angle connected or connectable to the spacer bracket. He is clamped with a rung by means of a clamping tongue.
  • Advantageously points the clamping device a slightly rotatably mounted clamping tongue with a lower area of the curved tip of the tongue and a clamping screw, such that in the assembled or tensioned state, the tip of the tongue slightly rungs engages below.
  • the clamping device also has an angular clamping rail rubber-elastic berths, which are intended to lie on the The top of the rung is on the side of the rung, and another means the clamping tongue graspable clamping point in the opposite corner of the Rung profile, so that the ladder standing aid when tightening the clamping screw is fixed to a rung.
  • the angular clamping rail extends over the essential part of the rung length, and the two angular berths The two ends of the clamping rail are for fixation, both in the plane of the Holmen determined as well as in the level of the ladder standing aid.
  • the described Refinements give the ladder standing aid a very stable bracket, which only with a force on the clamping screw can be released.
  • the after Clamping head designed below as an open component points with respect to a virtual one Clamping center line on one end side the screwing point and on the other end side the Clamping point, the joint for the clamping tongue approximately on the virtual Clamping center line is arranged between the clamping point and the screwing point.
  • the spacers are in the Area of the peripheral contact points in the manner of a tire spherical or convex trained to secure opposite point contacts for each usable attachment point.
  • the big advantage of this design is that the "real existing" investment situations or their specific ones Surface textures the spherical or convex shape is optimal in terms of to a stable contact point and thus a precisely definable position is selectable. It is common practice to carefully attach a ladder to the desired one Place with an optimal incline. However, before the person heads the ladder climbs, the ladder becomes perfect with a slight shaking motion Concern. According to the new solution, it doesn't matter whether the wall is uneven, e.g.
  • the still usable angular range of an outside corner preferably comprises also the range from 80 ° to 90 ° or at least 85 ° to 90 °. It follows thereby a total angular range between an acute-angled outside corner as well an acute-angled inner corner of approx. 250 ° to 270 °.
  • the inside of the two Spacer bracket is slightly concave to form opposing contact points for columns or posts. This makes it possible, even with relatively thin posts about 10 cm in diameter to use the ladder aid.
  • tie-up protection as close as possible to the ladder standing aid, e.g. in the form of a Straps to attach.
  • the entire range of usable investment locations is preferred a highly adhesive rubber covering.
  • FIGS. 1a and 1b show a preferred example of a ladder standing aid 1 with a view from above, fixed to a ladder 2, consisting of two bars 3 and rungs 4.
  • the ladder standing aid is mounted on the rung 4 by means of a clamping head 5 and towers over the ladder with a double bracket 6 in the direction of the setting side.
  • the Double bracket 6 has two opposite single bracket 7 with corresponding peripheral 8, marked with a thick black line. They are schematic three basic situations, a flat wall surface 9 (dash-dotted with two points), a 90 ° outer corner 10 (as a solid thick line) and an inner corner 11 (thick, dash-dotted line).
  • FIG. 2a shows the use of the ladder standing aid for columns or posts 20 or 21.
  • Each of the two single stirrups has a section W on the inside, with an over the entire length of concave contour 22.
  • the concave contour 22 allows formation from contact points 23 and 24, which have a very large area of application for columns and posts up to extremely small diameters.
  • With line 25 is a bandage protection indicated, which from the ladder standing aid around the pillar or the post can be stretched around and with a ladder for appropriate Working there is a hundred percent reliability.
  • W is the area for columns or Posts, X for outside corners, Y for straight wall surfaces and Z for inside corners.
  • Figure 3 shows a section III of Figures 1a and 1b and 2 through the Klemmkof 5.
  • the Klemmkof 5 itself can be designed in the same way for all solutions shown be and consists essentially of a clamping head part 30, which one after below, in the manner of an upside down, expanded "U”.
  • the Klemmkof 5 has a vise-like attachment 31 in the upper part and lower part a rung clamping part 32.
  • the clamping device settles together from the moving components, a clamping screw at head 33, a clamping thread 34, which has a nut 35 in the clamping head part 30 is anchored, also a clamping tongue 36.
  • the clamping thread 34 is rotatable mounted in the upper part of the clamping tongue 36 such that the thread adjustment transfers directly to the tongue 36 according to arrow 37.
  • the tongue moves depending on the current direction of rotation, on the clamping screw head 33 in Clockwise or counterclockwise around an axis 38 which is in the attachment 31 is firmly attached.
  • the clamping tongue 36 is in the lower clamping section 39 bent like a hook, so that the clamping section 39 any type of rung profile engages below.
  • Three positions of the clamping tongue 36 and three are shown different rung profiles. It can be clearly seen from FIG. 3 that the Clamping is optimal for every possible rung profile.
  • the clamping force generated is directed approximately in the direction of line 40 and presses the rung clamping part 32 to the Rung 4.
  • a clean clamping Clamping rail 45 with an upper pressing surface 42 and a lateral one Pressing surface 43, which each on a corresponding rung surface part 44 or come to rest on rungs side surface parts.
