Definitions
- the invention relates to ladders with two uprights connected by rungs, which form a foot end and an opposite upper end of the line and can be adjusted on wall surfaces.
- Ladders are probably the oldest tools for craftsmen; more and more also for household and leisure time, in order to quickly carry out small work processes at heights that are not accessible to humans.
- a very large variety of ladder models are produced: from, for example, the simplest wooden ladders, aluminum ladders, fixed ladders to complicated, for example combined pull-out and fixed ladders.
- Simple step ladders have the advantage that a certain distance between the user and the wall is created by inclining them against the wall, so that furniture, or any room body, or for example garden strips in the lower corner area are bridged from the floor to the wall in accordance with the length of the ladder and don't bother.
- step ladders there is an optimal angle of attack of around 70 °, which corresponds to safety-related standards and regulations.
- the bars of ladders are usually of a slightly springy construction, so that small bumps, or if the floor and wall do not form exactly two right-angled surfaces, are rebounded by ladder torsion. In many cases, however, it is not possible to completely eliminate larger deviations. In practice, therefore, the desired ideal conditions for employing ladders are unfortunately often not given, so that the user often makes dangerous compromises. He climbs the ladder, for example, if only the more or less hard point of a spar lies on the wall. The other employee is then brought up by the twisting of the ladder slightly, but uncertainly. Especially if the user does not have a good basic technical feeling, an unstable situation arises because the force effect of the user interacts with the inner tension of the conductor, with only limited contact pressure. In addition, in the case of such stresses, the two foot ends also receive destabilizing unfavorable forces, which result in dangerous accident situations.
- a further source of danger is that employing conductors in specific spatial conditions such as outside wall corners and / or inside wall corners is unfavorable - or not feasible, which is often disregarded by the conductor user. Even on posts / columns less than 40cm in diameter, a normal ladder may not be used without additional security. Leaflets are supplied by many accident prevention authorities and ladder manufacturers, on which reference is made to the fact that such risky applications are prohibited for avoiding corresponding major accident risks.
- the invention was based on the object, in particular to increase the safety for ladder users so that corresponding accidents can be avoided as much as possible, to greatly expand the safe use of ladders and also to avoid damage to buildings without the work on ladders or complicating the use of ladders. Furthermore, the invention was based on the further subtask of making existing ladders of various types / origins easy and safe to retrofit according to the invention and exchanging application-specific different ladder adjustment systems within seconds as part of a modular system.
- the solution according to the invention is characterized in that the two upper positions have support surfaces which can be brought into two spatial directions, or which are effective and arranged in pairs.
- the inventor has recognized that the problem of the ladder has so far only been seen on one or two levels for the manufacturer.
- a ladder In normal use, a ladder is placed on the floor and placed on the wall at a 70 angle.
- the conductor is dimensioned in accordance with the specified loads. The rest is up to the user.
- the contact surfaces are very particularly preferably arranged such that they contact the entire surface of the wall and are designed, for example, as interchangeable, adhesive pins with circular contact surfaces.
- the individual contact surfaces be paired / mirrored to a flat wall surface and / or to be arranged to the two surfaces of an inner and / or outer corner, the support surfaces being very particularly preferably designed as adhesive elements whose direction of action lie in a common effective plane - for multifunctional use for flat wall surfaces as well as for inner and outer corners.
- the common effective plane of the support surfaces is advantageously arranged transversely to the two spars, or this can be brought into a transverse plane which preferably makes an angle of approximately 110 to the spars.
- the line ends can be designed as an angled, fixed continuation of both spars and the support surfaces can be arranged on the line ends.
- the invention further relates to a ladder with two spars, which form a foot end and an upper end of the line, and is characterized in that both spars have an articulation point for an articulation axis in the area of the upper line of ends.
- the end of the line is designed as a stand that can be connected to the spars via the articulation points, the articulation points preferably forming an axis of rotation parallel to the rungs of the conductors.
- the parking support is angled approximately 110 to the spars and is limited in both directions of rotation by stops in such a way that it can be easily raised and lowered about the axis of rotation.
- the tests have shown that the vertical spring moment of an adjusting ladder, which is dependent on the user, is compensated by an articulated connection and instead of an adhesion-reducing slipping of the contact surfaces, an adhesion-intensive, permanent pressing of the contact surfaces is ensured. This reduces or eliminates the risk of accidents and damage to the wall surface.
- the contact surfaces are formed from individual, preferably interchangeable rubber or plastic-like adhesive elements, for example as rubber pins.
- the support surfaces can be designed as round or multi-surface shaped bodies, the support surfaces consisting of individual surface elements oriented in different spatial directions.
- the hiring ends are designed as a continuation of the two spars, which can be adjusted into a position angled to the spars via hinge-like joints, with both hiring ends preferably forming a rotating unit as prop supports.
- the invention further relates to a kit for a ladder with two bars, which a foot end and a The upper end of the line forms and is characterized in that the kit consists of at least two transition pieces which can be connected to the two spars in the region of the line of end and preferably have articulated points.
- Each transition piece can be formed in two parts; one articulated head part which can be plugged onto or connected to the bar end and a second clamping part which can be connected to it and which can be clamped along the bars, preferably with respect to a rung.
- the kit has protective caps in pairs, preferably made of rubber or plastic-like material, which can be connected to the transition pieces and thus the adjustment lead at the articulation points by means of quick-release fasteners.
- an adjustment support for a multifunctionally expanded range of conductor inserts which can be connected to the transition pieces via the articulation points and is designed as an inside and outside corner adjusting element, and as an adjusting element for normal walls.
- a securing element preferably a quick-action clamping element, is used for quick assembly or disassembly and / or replacement of various positioning supports or protective caps.
- the interchangeable, modular, multifunctional jack supports usually have articulated axes with excess lengths for both spars, for mounting on conductors of different widths.
- this is characterized as an adjustment support in that it has a plurality of elastic support surfaces which are arranged in pairs on two support arms. At least three elastic contact surfaces are preferably arranged on each support arm, the effective direction of which assume an angle, preferably of 45 ° twice, which are designed as a 3-function head. It has been shown that a step-up ladder with a stand-up support not only results in greater safety for the user, but also as a very special advantage in the case of greater safety due to the greater / optimal distance between the step-up ladder and the wall in the uppermost area.
- the positioning support has or have one or two hinge axes which are or are attached to the opposite side of the support surfaces and are preferably in a common plane with the support surfaces.
- the support surfaces are designed as exchangeable adhesive elements in one piece with differently oriented support surfaces, or as individual pins with an annular support surface.
- the positioning support which is movably attached to a central hinge axis, has four articulated support arms.
- the four support arms can each be brought into three different positions by means of 90 grids integral with the joint axis and used five times in a functional manner by 45 angled support pins.
- the preferably soft individual support pins are made of rubber and / or soft plastic, so that together with up to 8 times the contact surfaces only optimally reduced - and gentle contact forces on highly sensitive substrates, such as glass, are given.
- the support arms are very particularly preferably pivotably arranged for multifunctional use on flat surfaces and / or inside wall corners and outside wall corners.
