Definitions
- the anti-slip device can be 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 new anti-slip device can be folded in completely parallel to the outside of the ladder rail.
- split axles are guided through the rung cavities from the opposite sides to fasten the anti-slip device and screwed together within the rung. Centering cones on the outside of the split axles enable tight, play-free clamping on all shapes and sizes of ladder rungs.
- the new anti-slip device can be securely attached to all metal ladders regardless of make, ladder width, rung shape or rung size.
- the feet are equipped with profiled rubbers or earth tips.
- the new invention completely prevents the ladder feet from slipping, even in very critical contact situations, because the articulated, curved in length on the outside of the ladder rail in the lower ladder area, which can be folded in and folded out parallel to the outside of the ladder rail supports which can be extended in both directions and are adjustable in angle (6), FIG. 1, FIG. 6, FIG. 7 are mounted with articulated tie rods (3), FIG. 1, FIG. 6, Fig. 7 are connected, the opposite side of the tie rods (3) articulated with sleeves
- the hinged supports which can be pushed out and bent in both directions (6) Fig. 6, Fig. 7 in connection with the articulated pull and push rods (3) and with the movable and lockable Sleeves (5) the new anti-slip device is designed pivotable, so that only by pivoting z. B. the contact side to the rising side of the ladder, a wall support or a roof support or roof support is formed and the tie rod (3) Fig. 6, Fig. 7 are not extended by the advantageous curvature of the support (6) Fig. 6, Fig.
- a load distribution bar (11) Fig. 9 can be articulated, which adapts to all roof slopes.
- the load distribution bar (11) Fig. 9 is curved in length and angled at the ends (12) Fig. 9.
- the curvature provides bridges in the central region of the load distribution bar (11) Fig. 9 of abutting edges, humps, etc. of the roof surface.
- the angled ends enable the load distribution bar (11), which is folded in on the support (6) and held in position by spring tension (10), Fig. 8 and Fig. 9, when folded onto a roof. With the castors on the underside, easy shifting in the longitudinal direction is guaranteed.
- the load distribution bar (9), (11), Fig. 8 and Fig. 9 is connected in the region of the articulated attachment with the bent support thrust piece (6) on the inside of the curve with a tension spring (1), so that to When the supports (6) are folded in parallel to the outside of the ladder rail, the load distribution bars (9), (11) are parallel to the ladder rails with the help of the tension springs (10) and do not fold out and in uncontrollably.
- the curvature of the extendable supports (6) Fig. 8 allow the folded load distribution bar (9), (11) enough space so that the load distribution bar (9), (11) do not protrude from the underside of the spar.
- This advantage is a condition to the ladder with folded and equipped with load distribution bar anti-slip without snag z.
- Another novelty is the way the anti-slip device is attached to ladders, the rungs of which are led through the ladder stiles and are open on the end faces.
- the curved supports (6) FIGS. 6, 7 have a branching projection (7) FIG. 1 in the upper region.
- the branching jump (7) Fig. 1 is used to attach the support (6) on the outside of the conductor.
- the curved or even straight support (6) FIGS. 1, 3, 6, 7 remains fully extendable or telescopic in both directions.
- the supports (6) Fig. 1 can be articulated with the aid of split axes which pass through a ladder rung and are screwed inside the ladder.
- FIGS. 1, 2 are particularly advantageous.
- the conical centering stops (1) and (2) allow the split axes to be braced within the ladder rungs regardless of shape and The diameter of the ladder rungs and center themselves when the axes are screwed together.
- the supports (6) or the tie rods (3) are screwed to the thread ends protruding on both sides.
- the divided axes allow the anti-slip device to be attached to different conductor widths.
- the supports (6) Fig. 1, Fig. 6 and Fig. 7 consist of hollow profiles and are bent along their length. In the upper area there is a branching projection (7) on each support (6), FIG. 1, which is welded at least deeper by the hollow profile dimension from the continuous support profile end (6) FIG. 1.
- the branching jump (7) Fig. 1 is articulated with the ladder. Since the continuous hollow profile of the support (6) is not directly attached to the ladder, a telescopic, curved thrust piece can be pushed in and out unhindered in both longitudinal directions. Fig. L.
- the branching projection (7) Fig. 1 of the support (6) Fig. 1 also allows a distance to the ladder bar and thus a space to fold the tie rod (3) parallel to the ladder bar and also unobstructed behind the folded support.
- the opposite end of the pull rod (3) is attached to the ladder in an articulated manner, preferably below the support attachment, FIG. 1.
- the following type of fastening is available for ladders whose rungs are led through the ladder stiles and therefore have cavity openings accessible on the front.
- a threaded sleeve In one side of the ladder rung opening is a threaded sleeve, 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.
- the length of the threaded sleeve corresponds approximately to half the largest common conductor width.
- At the outer end of the centering cone (2) Fig. 2 there is a threaded bolt to which the tie rod (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 (2).
- the threaded rod can always be screwed in so that it only protrudes the necessary thread length for fastening the pull rod (3) or the branching branch (7) Fig. 1.
- a separate centering cone or cone (1) Fig. 2 is drilled longitudinally in the middle and is pushed over the protruding thread end up to the stop in the ladder rung.
- both centering cones (1) and (2) are centered on the edge of the ladder rung openings and braced independently of any rung shape or rung dimension.
- the type of attachment described is particularly suitable for retrofitting individual supports, etc. on ladders of different makes, ladder widths, rung dimensions and different rung shapes.
- load distribution beams (11) FIG. 9 are articulated.
- the ends of the load distribution beams 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 (11) has a curvature over the entire length.
- the load distribution bar (11) is fastened in an articulated manner to the curved telescopic support (6), FIGS. 8 and 9, with the top or outside of the curve.
- a tension spring (10) Fig. 9 is connected to the inside of the curved thrust piece of the support (6) and the outside of the curve of the load distribution beam (11) in the articulated area.
- Fig. 1 Slip protection mounted and folded in on both sides of the lower conductor area.
- Fig. 2 divided axes in the screwed state, with a slidable separate centering cone (1) and a threaded sleeve with a fixed centering cone (2).
- Fig. 3 leaning ladder placed on a lintel with a conventional wall support, standing on a step and secured with a straight anti-slip device to prevent the ladder feet from slipping.
- Fig. 4 leaning ladder with a conventional wall support placed on a wall and secured with a straight trained anti-slip device.
- Fig. 5 single ladder with a conventional wall support applied to a wall.
- the anti-slip device is folded in parallel to the spar.
- Fig. 6 leaning ladder with the help of a pivoted curved anti-slip device in the function as a wall support, placed on a lintel, on one
- Fig. 7 single ladder with the help of a curved anti-slip device and a load distribution bar placed on a gable roof and supported.
- the dashed drawing shows the advantage of the pivotable and pushable in the opposite direction bent thrust piece of the bent support.
- the length of the tie rod (3) remains unchanged.
- Fig. 8 on a leaning ladder folded parallel to the ladder bar curved anti-slip, the further advantage of the curvature of the support (6) can be seen.
- the folded load distribution bar (9) is due to the space gained in the area of the inside of the curve
- Fig. 9 at the ends angled (12) and in the length bent load distribution bar (11) of the support rollers.
