Definitions

  • the present invention relates to a device for wedging the legs of scaffolds of building construction and especially scaffolding during various works on walls.
  • the device can also be used for scale jobs.
  • the assembly of these scaffolding is traditionally carried out on irregular bearing soils, presenting either slopes, or projections between street and sidewalk for example.
  • Scaffold leg rigging is currently done with various means, usually wooden planks in order to make up for the horizontality of the ground. This brings a vertical wedging of scaffolding without any mechanical connection between the legs of scaffolding, wooden wedges and soil.
  • the support feet automatically adapt to the terrain configuration.
  • This tripod can be used too on flat ground to fit the feet of a ladder in its tube. We will have an inclination wanted between the tube and the ground to press the ladder to the wall in its upper part.
  • the rigid links (6a) and (6b) can be replaced by cables of equal or different length for simplification of manufacture.
  • a rising cable will cross for example two parallel cables descending or conversely thus ensuring perfectly their crossing. These cables will be protected by protective guides to their cross.
  • the outer ring (22) of adequate section will be designed with fasteners (12a) (12b) and (12c) at 120 ° on its periphery to support the support feet (5a), (5b), and (5c) by the intermediate axes (14a), (14b) and (14c) allowing the mobility of the support feet (5a), (5b) and (5c).
  • the bearing feet (5a), (5b) and (5c) have soles (7a) at their lower end, (7b) and (7c) in contact with the ground, mounted on axes allowing a few degrees of travel.
  • the soles (7a), (7b) and (7c) will be of different surfaces depending on the nature of the ground. On hard ground we will have soles with a non-slip rubberized protection fused from below. On soft ground, the soles surface will be larger with grip cleats for example.
  • the device FIG. 3 comprises a tube (10) having in its part superior three same fasteners positioned at 120 ° between them on the circumference of the tube (10) one of which (9a) FIG. 3 allows the articulation of the rod (6a).
  • the tube (10) has in its lower part three same fastening fasteners positioned at 120 ° between them on the circumference of the tube (10) of which one (9b) Fig.2 allows the articulation of the link (6b).
  • a first inner ring (21) is maintained at this last by two axes (1a) and (2b) which intersect at 90 ° in the same plane.
  • the axis (1a) goes to through two diametrically opposed holes (3) in the tube (10) and is free to rotate in these same holes.
  • the axis (2b) can be in three parts: two bolts - axes (4a) and (4b) are screwed symmetrically on a central part (4). 7, breakthrough at its center for allow the sliding and rotation of the axis (1a).
  • the axis (2b) 2 is not in solidarity with tube (10). It passes through two vertical slots (1) and diametrically opposed by relative to the axis of the tube (10).
  • the inner ring (21) serves to guide and reinforce the axis (2b).
  • a second outer ring (22) Fig. 2 lies around the first crown internal (21) and in the same plane.
  • the outer ring (22) is of greater diameter and is secured to the inner ring (21) via the axis (2b).
  • a free space is arranged between the rings (21) and (22). 3, to allow the crossing of the links (6a) and (6b).
  • This universal joint assembly allows the outer ring (22) Fig.2 its free displacement relative to the tube (10). We obtain an oscillatory movement of the crown external (22) relative to the tube (10).
  • the outer ring (22) Fig.2 has three pairs of fasteners (12a), (12b) and (12c) 120 ° on its circumference to maintain the three support feet (5a), (5b) and (5c). by via axes of rotation (14a), (14b) and (14c) allowing vertical deflection bearing feet (5a), (5b) and (5c) relative to the outer ring (22).
  • a half-moon (8) whose ends have two fasteners (8a) and (8b) to hold the links (6a) and (6b).
  • Each pair of links (6a) and (6b) is associated with a single foot support (5b).
  • the link (6a) is held at the upper attachment (9a) on the tube (10) and at its another end to the lower fastening (8a) of the half-moon (8) of the support foot (5b).
  • the link (6b) Fig.4 is held at the lower attachment (9b) on the tube (10) and at its other end to the high fixation (8b) of the half-moon (8) of the support foot (5b).
  • the drawing Fig.6 explains the operation of the tripod device
  • the tube (10) When placing the tripod on uneven ground with a slope or sidewalk, the tube (10) is found perpendicular to the direction of the slope. It will be enough to straighten vertically the tube (10) Fig.6 which performs a rocker around its center R Fig.6 and by the crossed play of the links (6a) and (6b) will constrain the triangle materialized by the axis (14a) Fig.6 and the two fixing pins (8a) and (8b) on the half-moon (8) to rotate in the vertical plane.
  • the mobility of the outer ring (22) by universal joint around the tube (10) allows the shaft (14a) to lift.
  • the support foot (5a) being integral with the three points fastening in rotation (8a) (8b) and (14a) forming a triangle, rises upstream of the slope. By symmetry is the other support foot (5a ') which is lowered downstream of the slope.
  • the outer ring (22) tends to follow in parallel the direction of the slope of the ground on which the device is placed when the tube (10) is vertical.
  • the central tube (10) directs automatically the inclination of the support feet (5a) and (5a '). If we maintain vertically the tube (10) thanks to the scaffolding leg fitted in the latter vertically, we have, by reaction of the ground on the support feet (5a) and (5a ') the device which comes to rest in adapting to uneven ground.
  • the device makes it possible to support the scaffolding without the contribution of various wooden wedges to create a stable and secure seat.
  • This tripod can be about thirty centimeters high on a diameter of forty centimeters at the soles. It is particularly useful for straight legs scaffolding but it can be used for ladders, trestles, etc ...
