Definitions

  • the invention relates to a scaffold with lifting and Lowerable boom according to the preamble of claim 1 or 6 or 7. It is known here, on work scaffolding and Work platforms boom to attach, the pivoting are formed, so they in different pivotal positions with an attached at the free end of the boom strut Stand on the ground and sit against the scaffold Secure tilting.
  • the boom essentially from an upper, longer-trained boom strut form, to which attaches a shorter, lower support strut. It is otherwise known, the boom strut and the Support strut with associated clamp couplings on the Frame profile of the work scaffold or the work platform too attach, with pivot points for the boom strut and the support strut are defined.
  • US-5,267,631A is a stabilizing apparatus for a Scaffolding became known on both sides of the scaffolding is arranged and one lower, one horizontal sliding support strut and a vertical, oblique extendible cantilever brace supported on the ground includes.
  • the boom stay is with one, at the upper part connected to the scaffold hinged and hinged in this swivelable and obliquely exposed to the scaffold.
  • the lower strut is with one end with a slidable retaining sleeve of the boom strut hinged pivotally connected, and with its other end in one horizontal guide tube horizontally displaceable added. Two of these horizontal guide tubes are for Stabilization via connecting pins coupled together.
  • the entire stabilizing apparatus has no or only decreased support function as the shift of Support strut on the boom strut virtually limitless and is unlimited, because the sliding holding sleeve a unlimited displacement allowed on the boom strut.
  • FR-1 147 627A shows only a foldable support strut, which is arranged on a boom strut. This is the Linkage of the support strut to the cantilever strut in such a way changeable, that the effective length of the support strut can be influenced.
  • this Support strut in one connected to the boom strut Holder arranged, but this holder is not fixed to the Boom stay connected.
  • the pivot point within this Holder is not movable or repositionable, but he is trained only swivel, because a bendable support strut is shown, which is especially true at Photo tripod is used.
  • the cantilever strut is not height adjustable, because it can only to a certain height be set.
  • the height is determined by the application of the ring at the central center mast, which is no Height adjustment of the boom strut according to the present Invention represents.
  • the invention is therefore the object of a Mobile scaffold or a working platform or a portable To develop the frame so that the boom without loosening the Attachment points of the struts of the boom or moving arranged on the frame profile of the mobile scaffold Clamps, from his driving position in his Support position and can be brought back.
  • An essential feature of the invention is that the linkage the support strut either on the frame profile of the mobile scaffold or on the boom strut is changeable by a distance, which changes the effective length of this strut.
  • An essential feature of the invention is therefore that the effective length of the support strut compared to the fixed length of the boom strut changeable is trained.
  • the pivot point of the support strut on the Boom strut is formed in a holder and that this pivot point in a certain way displaced or is formed pivotable or repositionable, namely such that in the one pan, shift or Plug position of this pivot point the effective length of Support strut is short, so that the boom a gets downslope situation, which ensures that the am free end of the jib arranged stand on the ground rests.
  • the articulation point is displaced, reconnected or is pivoted, then raises the boom strut with her free outer end from the ground and the boom is thus free, leaving the mobile scaffold or the work platform free is movable.
  • this Anschddling is slidably guided in a backdrop, wherein the backdrop is oriented so that the invention provided effective change in the length of the support strut is reached.
  • the displacement is a transposition of the articulation point, wherein a transfer, e.g. by means of screws and associated Nuts can be done.
  • Umstecksent that e.g. the point of articulation from a lower position to an upper one Position can be transferred to an associated holder.
  • this articulation point in the range of Lever arm is arranged so that with the pivoting of a hand lever, the entire lever arm from a position in another one can be pivoted, thus creating the free end This lever of the previously described pivot point of Support strut is arranged.
  • the displacement of the articulation point in this bayonet-type Kulisse can here via a rotary sleeve or over a Sliding sleeve take place, which ensures that the Link point from one stop position to the other Stop position of the backdrop is moved and hereby also the effective length of the support strut is changed.
  • the subject of the present invention provides not only from the subject of the individual Claims, but also from the combination of individual claims among themselves.
  • FIG. 1 the part of a rolling tower 1 is shown, wherein it can be seen that on the frame section 2 of the rolling tower 1, a boom 3 is arranged.
  • the boom 3 consists of an upper boom strut 4 with arranged at its free, front end stand 8, which rests on the floor 9 and a shorter support strut 5, which engages in the manner of a simple lever arm in a holder 10 on the boom strut 4 on the one hand and on the other hand is pivotally mounted via a clamping coupling 7 on the frame profile 2.
  • the boom strut 4 is pivotally attached to the frame profile 2 in an upper clamping coupling 6, wherein a pivot point 11 is defined.
  • a pivot point 12 for the support strut 5 is formed in the lower clamping coupling 7.
  • the support strut 5 forms in its point of articulation 15 also a pivot point 13 in the holder 10th
  • FIG. 2 shows that the displacement of the articulation point 15 takes place in a backdrop 16, wherein the pivot point 15 in lower stop 20 of the gate 16 is located. This is the effective length of the support strut formed short and thus is also the stand 8 on the floor 9.
  • the shape of the backdrop 16 is chosen so that the plant the pivot point 15 in the two stops 19,20 is advantageously self-locking, i. she can do not change alone.
  • FIG. 4 shows this case, where it can be seen that the Anschtician 15 is in the upper stop 19 of the gate 16 located.
  • the holder 10 is otherwise made of a U-shaped Metal part with two mutually approximately parallel Side cheeks 23,24, at their front, free ends of the opposite slot-shaped scenes 16 have, which are parallel to each other and each other aligned.
  • the two scenes 16 are penetrated by the bolt 34, which has a screw head 25 on its one side, which rests against the outside of the side wall 23.
  • a nut 26 is screwed onto the bolt, which is connected to a handle 27.
  • FIG. 4 shows that the base 8 only has a small amount Measure from the ground 9 lifts. This has the advantage that even if the change in the effective length of the strut from the Travel position of the boom to the support position of the boom was forgotten, but a certain tip over security for the Mobile scaffolding during the procedure and also during the unauthorized use in driving position is secured.
  • FIG. 7 shows, as a further exemplary embodiment, that the effective length of the support strut 5 also by a change the length of the support strut itself can be achieved.
  • the support strut 5 consists of two nested telescopic part tubes 29,30, in the area of a backdrop 31 is arranged.
  • the one sub-pipe 29 is connected to a bolt 32 which is displaceable and fixable in the other part of the pipe 30 arranged in the gate 31 between the two stops 19,20.
  • the effective length of the two partial tubes can then be lengthened or shortened by the dimension 35.
  • FIG. 8 shows, as a further exemplary embodiment Possibility that the effective length of the support strut through Pivoting the articulation point 15 can be changed.
  • a holder 36 is arranged on the boom strut 4, in which in a pivot point 37, a lever 38 pivotally is stored, the at its front, free end of the Anlenk Vietnamese 15 carries, which is rotatable with the end of Support strut 5 is connected.
  • the lever is in its upper Pivoting position (as in Figure 8 in solid lines drawn), then the effective length of the Support strut long and thus raises the stand 8 of the boom off the ground. If, however, the lever 38 in the direction of arrow 39th swung down to get into position 38 ', then the effective length of the support strut 5 is shortened and the boom sets with his stand 8 on the floor. 9 on.
