Definitions
- the invention relates to a slip protection for ladders according to the preamble of claim 1, as is known for example from US Pat. No. 5,165,501 and GB-1,260,476.
- the known anti-slip device has the disadvantage that a relatively large number of screws have to be loosened or a lot of manipulations are required to attach it to different places on a ladder and to adjust and fold the anti-slip device.
- the object of the invention is seen in improving a generic anti-slip device in such a way that it is easy to attach and detach both at the foot and at the head end of a ladder, which gives the ladder a secure footing in different situations and easily in the longitudinal direction of the ladder completely can be folded.
- the anti-slip device is also particularly suitable for stairs if the ladder feet e.g. stand only just at the edge of stairs because the ladder is placed against a wall parallel to the incline of the stairs.
- the anti-slip device can be easily mounted on the upper area of the ladder and can be used as a wall support or as a roof support equipped with load distribution beams.
- the anti-slip device can be folded in parallel to the outer side of the stile, regardless of the position of the supports.
- the column fillings 6 (FIGS. 1, 6 and 7) consist of hollow profiles and can be bent along their length. In the upper area there is a branching projection 7 (FIG. 1) on each support guide 6, which is welded at least deeper from the continuous support profile end by the hollow profile dimension.
- the branching projection 7 (Fig. 1) is articulated to the ladder. Since the continuous hollow profile of the support guide is not attached directly to the ladder, a telescopic, curved thrust piece or support can be pushed in and out unhindered in both longitudinal directions.
- the branching projection also allows a distance from the ladder bar and thus a space to fold a strut running parallel to the ladder bar and behind the folded support also unimpeded.
- a sleeve 5 (FIG. 1, FIG. 6, FIG. 7) which is designed in accordance with the radius of curvature and the profile and is designed to be displaceable and lockable.
- the strut 3 (Fig. 1, Fig. 6, Fig. 7) is articulated or rotatably mounted at one end. The opposite end of the strut is preferably articulated on the ladder below the support attachment (FIG. 1).
- the following type of fastening is suitable for ladders whose rungs are led through the ladder stiles and therefore have cavity openings accessible from the front.
- a threaded sleeve is inserted into one side of the ladder rung opening, the opposite end of which has a centering cone or cone 2 (FIG. 2), the largest outer diameter of which is larger than the largest inner dimension of any ladder rung. This corresponds to the length of the threaded sleeve is approximately half the largest common conductor width.
- a threaded bolt At the outer end of the centering cone (Fig. 2) there is a threaded bolt to which the strut 3 (Fig. 1) or the branching projection 7 (Fig. 1) can be screwed.
- a threaded rod is inserted into the opposite side of the ladder rung opening and screwed into the threaded sleeve with a fixed centering cone.
- the threaded rod can always be screwed in so that it only protrudes the necessary thread length for fastening the strut or the branching projection (Fig. 1).
- a separate centering cone or cone (Fig. 2) is drilled lengthways in the middle and is pushed over the protruding thread end up to the stop in the ladder rung.
- Load distribution beams 11 can be articulated on both telescopic supports of the curved support guides 6 (FIG. 7).
- the ends of the load distribution bars are angled 12 (Fig. 9) and provided with rollers at both outer ends and in the angular range.
- the central area of the load distribution bar has a curvature over the entire length.
- the load distribution bar is articulated to the curved telescopic support (FIGS. 9 and 9) with the top or outside of the curve.
- a tension spring 10 (FIG. 9) is connected to the inside of the curved support and the outside of the load distribution beam 11, preferably in the joint area.
- the anti-slip is designed pivotable, so that only by pivoting
- the landing side to the rising side of the ladder is a wall support or a roof support or roof support and the strut 3 (Fig. 6, 7) does not have to be extended by the advantageous curvature of the support guide 6 to the application point of the resulting wall support at right angles or horizontally vertical height of the attachment point of the extendable curved supports to hold the ladder. Due to the curvature of the column guides, sufficient lateral freedom remains despite the unchanged length of the struts 3.
- the curvature of the load distribution bar ensures bridging in the central area of the load distribution bar from abutting edges, humps, etc. on the roof surface.
- the angled ends enable the load distribution bar, which is folded in on the support and held in the folded position with a spring, to be unfolded when it is placed on a roof.
- the tension spring is connected in the area of the articulated attachment to the curved support on the inside of the curve, so that the load distribution bars are also located in addition to the supports folded in parallel to the outside of the ladder rail and do not fold out and in uncontrollably.
- the curvature of the extendable supports allow the folded-in load distribution bars enough space so that they do not protrude from the underside of the ladder rail. This is important so that the ladder with the anti-slip device folded in and provided with a load distribution bar without getting caught e.g. can be pushed onto a roof rack.
- the load distribution bar can be moved slightly in the longitudinal direction.
- the curved support guides 6 (Fig. 6. 7) have a branching projection 7 in the upper region, which serves to fasten the support guides on the outside of the conductor, the curved or straight supports remain fully extendable or telescopic in both directions.
