Definitions
- the invention relates to a resting platform for ladders with a step surface which can be pivoted about a vertical axis running next to the ladder between a use position and a waiting position and can be locked in these positions.
- the tread In the use position, the tread is in front of the rungs of the ladder and in the waiting position, the tread is pivoted to the side.
- Resting platforms on ladders are used to rest a person in a standing or sitting position and as a standing surface when working at high heights.
- DE-GM 90 01869 is a resting platform of the type mentioned for crampons on buildings, for. B. chimneys or masts known.
- the tread of this resting platform is fastened to a swivel tube which is rotatably mounted on a hinge rod, the swivel tube being supported on a latching sleeve which is arranged on the hinge rod so as to be longitudinally displaceable.
- the step surface is locked in the use position and the waiting position by this locking sleeve. If the person who climbs the ladder has exceeded the resting platform in the waiting position, he can lift the footplate with his foot so that the swivel tube is released from the locking sleeve and pivot the footplate into the use position.
- the entire tread surface must be raised with your foot so that the hinge tube is released from the locking sleeve.
- the hinge rod and the swivel tube extend at least over two rung distances, which increases the weight to be lifted with the foot.
- the invention has for its object to provide a resting platform for ladders, which can be pivoted from the use position into the waiting position and back with relatively little effort.
- the locking device has an actuating device which can be actuated with a foot by a user standing above the step surface to release the locking.
- the resting platform according to the invention is particularly suitable for central spar or single spar ladders in which the spar is a square or C-profile with an opening pointing forward.
- the rungs penetrate the profile and the opening of the profile is used to guide climbing protection.
- the device for locking the tread surface in the use position preferably has an angle lever articulated on the tread surface with two lever arms, of which the free end of the first lever arm projects laterally beyond the tread surface , so that it can be reached at its free end by the user by foot, and a locking bolt is provided at the free end of the second lever arm, which engages in the rest position of the angle lever in the opening of the square or C-profile of the central spar and itself releases from this opening when the angle lever is pivoted out of its rest position by actuating the free end of the first lever arm.
- the angle lever is expediently arranged such that the free end of the first lever arm, e.g. must be lifted over a pedal plate attached there. This prevents accidental kicking on the pedal plate, i.e. by a downward movement of the free end of the first lever arm, the tread is released from its position of use.
- the locking device preferably has for Locking the tread in the waiting position on a pawl mechanism, the pawl mechanism containing a foot-operated pawl.
- the step extension In the use position, the step extension preferably lies on the ladder rung, so that the hinge does not have to bear the entire weight of the person standing on the resting platform, but this weight is derived by the step extension on the ladder rung.
- Fig. 1 the rest platform in the use position in plan view
- FIG. 3 shows the resting platform in a side view looking towards the rung and in FIG. 1 from the left;
- FIG. 4 shows a section according to A - B of FIG. 1;
- Fig. 5 shows the view G of Fig. 4
- a resting platform is attached to a central spar or single spar ladder with a climbing protection device, as is known from DE-PS 1961757 and EP-0129 241.
- the ladder 1 consists of a central spar 2 which carries rungs 3.
- the central spar 2 has a square or C-profile with an opening 8 extending along the front side. This opening serves for guiding the slide of DE-PS 1 961 757 and EP-A-0 129 249 known fall arrest system.
- the fall protection device is not shown in the drawing.
- the resting platform is screwed to the rear of the central spar 2 by means of a fastening bracket 4, two hinge brackets 9 of the fastening bracket 4 extending to the right beyond the rungs 3.
- a tread surface 10 is hinged to the mounting bracket 4 laterally next to the rung ends by means of a hinge 5, the hinge sleeve 6 holding the tread surface 10 via a connecting bracket 7.
- the tread surface 10 is stabilized by a diagonal bracing 13.
- Fig. 1 the tread surface 10 is shown in its use position.
- the tread can be pivoted counterclockwise into its waiting position.
- the tread surface 10 is locked both in the use position and in the waiting position.
- Two tread extensions 14 point forward from the tread surface 10, which in the use position rest on the rung 3 of the ladder 1 and thereby transfer a substantial part of the weight of a person standing on the tread surface 10 to this rung 3.
- the step extensions 14 rise slightly towards the front so that they slide onto the rung 3. As a result, the hinge 5 is less stressed and can be carried out more easily.
- This locking device for locking the step surface 10 in the use position.
- This locking device consists of an angle lever 15 which is articulated below the tread on a bearing plate 16 which projects downwards in the middle of the front of the frame 11.
- the angle lever 15 has a first, horizontally extending lever arm 17 and a substantially shorter, vertically standing lever arm 18.
- the angle lever 15 is articulated approximately at the intersection of the two lever arms 17, IS.
- At the free end of the shorter, vertical the lever arm 18 is a locking pin 19 is provided, which first widens step-like at its front end and then tapers again frustoconically.
- This widening 20 is one-sided, ie it only extends over an angle of approximately 180 °.
- the spreading 20 engages behind the edge of the opening 8 in the front of the central spar 2.
- the widening 20 is oriented so that the angle lever 15 is rotated in the locking direction by the gravitational torque of the horizontal lever 17.
- the horizontal lever arm 17 projects laterally beyond the boundary of the step surface 10 and a pedal plate 21 is attached to this projecting end.
- the pedal plate 21 By lifting the pedal plate 21, the locking pin 19 is brought out of engagement with the edge of the opening 8 and the lock is released.
- a person standing on the next rung 3 lying above the step surface 10 can easily lift the pedal plate 21 with his left foot and thereby release the locking of the step surface 10 and pivot the step surface 10 into the waiting position.
- the locking device of the waiting position has a pawl 22 which engages behind a locking bar 23 for locking.
- the locking bar 23 is screwed onto the mounting bracket 4 and passes behind the hinge 5.
- the pawl 22 protrudes horizontally from a square bar.
- Square rod 24 is guided in a vertical square tube 25 screwed to the connecting bracket 7, the pawl 22 being loaded by its own weight in the locking direction.
- the waiting position of the step surface 10 can be adjusted by a stop screw 26 so that there is only a minimal play between the pawl 22 and the locking bar 23.
- the stop screw 26 rotates in a thread cut into the locking bar 23 and is secured with a nut 28.
- the square rod 24 is extended upwards beyond the pawl 22 and is provided at its upper end with a guer extending handle 27 which is approximately parallel to the tread surface 10 in the waiting position the rungs 3 runs.
- a person can pull the handle 27 upwards a little with their right foot and thereby raise the pawl 22 until the step surface is locked 10 is solved.
- the tread surface 10 can then also be pivoted clockwise from FIG. 1 into the use position with the right foot, so that the tread surface 10 strikes the central spar 2, the locking bolt 19 engages behind the edge of the opening 8 and the two treads Extensions 14 rest on the rung 3.
- the swivel angle is approximately 105 °. After this process, the person can enter the step surface 10 and take a break there, for example.
- the locking device must be adapted accordingly for the position of use and a different locking device should be used instead of the locking pin 19, e.g. the ladder can snap into place with a rung.
- the mounting bracket 4 is to be adapted to the type of conductor used.
- the embodiment described above and shown in the drawing is the right-hand version, in which the hinge 5 is located to the right of the central spar. Of course, a left-hand version is also possible.
