Definitions

  • the present invention relates generally the area of scaffolding, and it relates, more particularly to a rolling scaffold which is therefore mobile, suitable for work at low or medium height, at inside or outside buildings.
  • a commonly proposed replacement solution for work at relatively low height, consists in a stepladder with access from the outside.
  • a stepladder In order to closer to scaffolding, such a stepladder can be fitted with railings in its upper part.
  • stepladder is an unsuitable solution and dangerous, which should be outlawed.
  • the present invention aims to eliminate all disadvantages previously mentioned, by providing a rolling scaffolding type device, therefore stable and offering a large work surface, which further offers a simple, convenient and secure solution for accessing the work floor, even in the case of a work floor work located at a low height and preventing access from the inside.
  • the subject of the invention is a rolling scaffold, of the kind comprising a base provided stabilizers and wheels, two vertical frames opposite forming scales, and at least one floor of work hung by its two ends respectively opposite frames, protective guardrails being associated with or with each floor, characterized in that, to allow access to this floor from the outside of the scaffolding, it has two opposite frames forming scales of unequal heights, with a frame of lower height located on the side provided for access, and a larger frame located on the opposite side, the upper part of the tallest frame having a railing front element function, while two other side railing elements are provided, each equipped, at their two opposite ends, with attachment means adapted respectively to the frame of smaller height and larger frame.
  • the inventive idea is to make a asymmetrical rolling scaffolding, in particular as regards concerns the two ladder frames, which are present as two scales, one of which is higher than the other, and has more bars important.
  • the work floor is positioned at the top of the scaffolding, hanging from the last smallest frame bar and bar corresponding intermediary of the larger framework height, access to the floor becomes extremely easy, since the user climbs on the rungs of the ladder formed by the frame of smaller height, this by outside, and access directly to the floor, when it reaches the top of this ladder.
  • the invention by allowing high access from the outside and no longer by interior, removes hatches in floors and allows to realize these in a simpler and more economical, while improving safety (removal of risk of falling through a hatch that remains open).
  • the scaffolding which is the subject of the invention ensures the safety of the operator working on the floor, by providing the two railing elements side, complemented by the front railing element formed by the upper part of the larger frame height, which necessarily exceeds above the floor of work, at one end of the latter.
  • each of the two side railing elements also has an asymmetrical configuration, with at least two horizontal rails connected between they, at one end, by an additional vertical upright low height, designed to be hung on the frame more great height, especially at the top of this frame, and at the opposite end, by a vertical upright of greater height, extended down below the bottom rail and thus adapted to be hung on the smaller height frame.
  • the extreme amounts of the two side railing elements, thus shaped, are positioned laterally and outward, relative to the uprights of the two frames forming ladders.
  • the rolling scaffolding shown in Figure 1, includes a base 1 called "cross”, comprising four telescopic stabilizers 2 (shown here in retracted position) and four wheels 3.
  • Both opposite frames 4 and 5 are interconnected by at least a diagonal 10, located on a longitudinal side of the scaffolding.
  • the two opposite frames 4 and 5 are of unequal heights. We can thus distinguish a first frame 4 of smaller height h, having for example three bars 8, and a second frame 5 larger height H, for example having six bars 9, therefore clearly protruding above the first frame 4.
  • the scaffolding also has a work floor 11, rectangular, which is surrounded by a plinth 12 and has hooks at both ends 13 and 14 respectively with locking members.
  • the work floor 11 can thus be hung at height desired, between the two opposite frames 4 and 5, the hooks 13 and 14 cooperating respectively with a bar 8 of the frame 4 and a bar 9 of frame 5 located at the same height.
  • the floor 11 can be hung, on the one hand, to the bar 8 upper part of frame 4 of smaller height h, and other share, at the corresponding bar 9 (for example the third bar 9 from the bottom) of the larger frame 5 height h.
  • the upper part 15 of frame 5 of greater height protrudes above the work floor 11, at one end of the latter, and thus constitutes a front railing element.
  • the scaffolding has two more elements side rails 16 and 17, configuration asymmetrical.
  • Each side railing element 16 or 17 has an upper horizontal rail 18 and a lower horizontal rail 19, connected to one another end by a short vertical upright 20, and connected between them, at the opposite end, by an upright vertical long 21, which is extended downwards, below of the bottom rail 19.
  • the short upright 20 is provided hooks 22 for fixing to the upper part 15 of the frame 5 of greater height H.
  • the long upright 21 is provided, on its lower extension 21a, with hooks for fixing it to the smaller frame 4 height h.
  • the two side railing elements 16 and 17 can be mounted, each between the two opposite vertical frames 4 and 5, above the floor of work 11, the extreme amounts 20 and 21 of each railing element 16 or 17 taking place laterally and outwards, relative to the adjacent uprights 6 and 7 belonging to the two frames 4 and 5.
  • the long uprights 21 of the railing elements 16 and 17 extend, upwards, the uprights 6 of frame 4 by smallest height h.
  • a rolling scaffold is thus obtained, in which access to the work floor 11 is achievable from the outside, using the ladder formed by the frame 4 of smaller height h for direct access, without obstacle, on this floor 11.
  • the ladder formed by the frame 4 of smaller height h for direct access, without obstacle, on this floor 11.
  • the rolling scaffolding mounted on the Figure 1 is a relatively small scaffold height, including the two vertical frames 4 and 5, relatively short, both are made of in one piece.
  • the frame 4 of smaller height remains in one piece, and for example has six bars 8.
  • the other frame 5, of greater height is formed of two elements 23 and 24 in the form of scales, superimposed and nested.
  • the lower element 23 has for example six bars 8, while the upper element 24 has for example three bars.
  • the lower element 23 of the frame 5 greater height may be identical to frame 4 of smaller height, opposite which it is located.
  • this configuration is not changed for the remains, and it retains in particular the principle of access to work floor 11 from the outside of scaffolding, using the ladder formed by the frame 4 of smaller height.
  • the floor again can be hung on the level of the upper bar 8 of frame 4 of smaller height, or at a lower level, the side railing elements 16 and 17 being adjusted in height so corresponding.
