Definitions
- the invention relates to a working platform, which has a scissors mechanism with a lower pair of scissor arms, which with at least one upper arranged above Pair of scissor arms is connected, retractable and extendable.
- Such work platforms are known, for example from FR 2 197 397 A. They are in the Usually arranged on a chassis and can be extended hydraulically on site persons or objects on the platform to the desired level Height to convey.
- the object of the invention is thus to provide a working platform, wherein the transport height is minimal, without sacrificing stability and load bearing capacity Need to become.
- a working platform which has a Scissors mechanism with a lower pair of scissor arms, which with at least connected to an upper pair of scissor arms disposed thereon, on and can be extended, solved by the fact that the cross section of the scissor arms decreases towards the top and that the upper pair or the upper pairs of scissor arms on the insides to their the upper end has an outwardly directed bevel, or by having an obliquely attached upper end of the scissor arms is formed.
- the length of the chamfered upper end of the scissor arms relative to the total length of the scissor arms of a pair of scissor arms the overlying pair of scissor arms increases.
- the work platform according to the invention on several superimposed arranged pairs of scissor arms 1, which has a in the range of lower pair of scissor arms I arranged and attacking at this Hydraulic drive 2 is extendable and collapsible.
- the pairs of scissor arms are 1 each pivotable about a central axis 3 and at its upper end 4 with the lower ends 5 of the overlying pair of scissor arms 1 connected.
- the upper pairs (II, III, IV and V) of scissor arms 1 at its upper inner sides 6 to the upper end 4 towards the outside 7 directed Bevel 8 have.
- This bevel 8 allows the folding of the Scissor arms 1 (Fig. 2), without that between the superimposed scissor arms 1 a Gap remains free.
- this can Be made chamfer 8 without loss of stability.
- For the same reason can also be reduced in cross-section of the scissor arms 1 from bottom to top, resulting in a further weight and transport height reduction leads.
- Fig. 3 shows the formation of the scissor arms 1 from the lower pair (I) to the uppermost Couple (V). It can be seen that the lower pair (1) one over the entire course having constant cross-section.
- the overlying pair (II) is connected to the upper inner sides 6 to the upper end 4 toward an outside 7 directed Bevel 8 is provided, i. on the upper inside 6 material was removed or reduced the cross section. The outside 7, however, remains unchanged.
- the bevel achieved in that the upper end 4 of the scissor arm 1 obliquely to the outside 7 of Scherenarmes 1 directed to the remaining part of the scissor arm 1 is attached.
- the attached upper end 4 have a smaller cross-section than the remaining part of the Scissor arm 1.
- the bevel 8 expediently takes place (i.e., the angle between the remainder of the scissor arm 1 and the bevelled one upper end 4) towards the top, as well as the length of the chamfered upper end 4 of the scissor arm 1 in relation to the total length of the scissor arm 1 upwards increases.
