Working platform

The invention relates to a suspendable work platform which is attached to a support device on the side of a workpiece can be hung.

Such work platforms can be used in the construction industry, for decoration s purposes or the like. They can be useful, for example, when the masonry of a house, a factory or factory chimney

should, with the need that the work platform can easily be put together to different lengths, so that a barrier-free walkway is created from which a worker can work with minimal effort. It is "the object of the present invention to provide such a suspended work platform.

The working platform according to the invention is characterized by the combination of at least one floor segment, at least two side segments and at least two suspension parts, each suspension part having two side parts with devices for attaching the side segments and an upper cross piece with devices for attaching suspension means for the work platform be provided here with a lower cross-piece that extends between the two side parts.

The working platform preferably has end segments through which the floor segment or floor segments and completed the walkway formed by the side segments so that a person working on the platform is effectively locked and cannot easily fall off.

It has turned out to be advantageous to combine at least two of the floor segments and their associated side segments with one another by means of an articulated connection, so that the floor segments can be pivoted relative to one another. For example, the two floor segments and their associated side segments can be connected to one another by a connecting segment through which the articulated connection '■

is established between the two floor segments, the connecting segment having a floor plate. The connecting segment advantageously has side plates and rails attached to them, by means of which the formation of a gap between adjacent side segments of adjacent floor segments is prevented. It has been shown that with a maximum inclination of a floor segment of 15 ° gegenül
safe working is possible.

Ground segment of 15 ° to the horizontal

Preferably the entire work platform is made of metal, although it is of course possible that one or several ropes also consist of a different material such as a rigid plastic product can. A particularly useful metal for making the aerial platform is an aluminum alloy, as one of them manufactured working platform is both stable and light. In addition, an aluminum alloy has a shiny clean appearance and is not easily corroded under normal Working conditions.

Each end of a floor segment can be designed so that it can be attached to the side segments or reaching over them or that there is one pointing downwards ündrand owns the over the lower cross piece of a hanging part grasps. If the floor segments grasp over the lower cross pieces of the hanging parts, they will be preferred additionally connected to the cross pieces of the suspension parts by suitable fasteners. When the walkway through one end segment is completed, the outermost segment can follow

downward-facing end edge of the last floor segment over the grab the lower cross member of such an end segment. if the walkway is not closed by an end segment, a hanging part is provided at the end of the walkway, to which the outermost end of the last floor segment and its side segments are attached.

In such cases in which two or more floor segments are connected to one another, it may often not be desirable to attach a suspension part to the connection point which serves as a support member for the floor segments and for the side segments. As a result, a connecting part can be used at such a junction between the floor segments.

The side segments of the work platform can be made of pipes be formed and preferably consist of welded tubes made of aluminum alloy, so that an open frame

. construction is present. In general, the side segments comprise an upper and lower one parallel to the

. Floor segment or the floor segments extending tube, the ends of which are flattened and for connection to the suspension parts to serve.

The suspension part preferably has a rectangular area, the upper cross piece having an A-shape. In the upper part of the upper cross piece, an opening is expediently made in which a rope or a hook is attached on which the work platform can be hung. The side parts of the hanging part are with receiving devices provided in which the flattened ends of the upper and lower tubes of the side segments can be attached. Preferably, the receiving devices and are flattened Ends of the upper and lower tubes are apertured so that the side segments are fastened with bolts or pins, for example with pins provided with snap lugs, with the

Suspension parts can be connected.

The end segments of the working platform can each have two side parts, preferably of rectangular cross-section and at least comprise a lower cross member. You can use side panels of the end segments have protruding U-shaped tabs that form the flattened ends of the upper and lower tubes of the side segments take up; The flaps are provided with openings, so that the end segments can be connected to the side segments via bolts or the like.

The working platform according to the invention can be suspended from a support device by means of ropes, cables, wires or the like and by means of winches that can be operated manually, electrically, pneumatically or hydraulically, for example and be lowered. For this purpose, winches that can be operated manually or by a power source, such as they in their own application ITr, submitted on the same day. are described on the working platform to be appropriate. At the Y- ^ w:, j dung by hand-operated Winches, these can be attached to one or two side parts of a hanging part, one being attached to the winch leading cable can first be guided around two rollers attached to the upper end of the suspension part. Palis may be desired the working platform can be attached to the wall of a building and moved up and down in relation to the attachment points will.

Because the working platform according to the invention can be assembled differently, it can also be used on round structures such as chimneys _for cooling towers, tanks and gasometers. In a form suitable for particularly high demands, the working platform has a ^: heated interior with facilities for power-operated tools, which means that outdoor work can only be carried out under conditions that are otherwise only possible inside buildings. In addition, the working platform can be assembled and ready for use in 1/10 of the time that is required to erect traditional construction equipment made of tubes.

The supporting beam shown in FIG. 4 is designed in such a way that it can be connected to upper cross pieces 14 by means of bolts or the like of suspension parts 10 can be connected.

The support member shown in Fig. 5 comprises a Cross member 50, over which the floor segments 2 grasp, and two side parts 52 and 54? on each of which a support 56 and 58 is attached «At the upper ends of the side parts 52 and 54 is one Flap 60 or 62 attached, via which the connection to the side segments 16 can be made.

The working platform shown in Fig. 6 has floor segments 2, suspension parts 10 and side segments 16, which correspond to those already described with reference to FIGS. There are two adjacent floor segments 2 separated from one another by a connecting segment 80; As As best seen in Figure 8, each of these connecting segments 80 has a bottom plate 82 upwardly directed side plates 84 and guide rails 86. The bottom plate 82 is in the assembled state of the Working platform arranged between two floor segments 2, while the guide rails 86 by the insertion a connecting segment 80 between two adjacent Side segments 16 span the resulting space. The side plates 84 are in the shape of a right triangle with the guide rails 86 on, respectively attached to the longest side of this triangle. In the embodiment according to FIG. 6, the intermediate A-A. Repeat the area on both sides.
