Definitions

  • Stanchions used in construction work to support loads comprise two coupled telescoping tubes, so that one slides inside the other in order to adapt the length to the separation between the surfaces to be supported.
  • Spanish Utility Model 9501894 describes a stanchion with means providing a safety device to prevent the inner tube from exiting the outer tube, for which a tab is provided transversely housed in corresponding diametrically opposite orifices made in the inner tube itself, with the length of this tab slightly greater than the diameter of said tube, and aided by a ring externally placed on said inner tube and free to move on it, with the inner diameter of said ring smaller than the length of the tab, additionally provided with a pair of securing bolts transverse to the tab and placed near the ends of said tab, spaced so that they prevent an excessive displacement of the tab through the orifices of the inner tube where it is housed.
  • This safety system or device for preventing the exit of the inner tube from the outer one has structurally complex characteristics, without providing an effectiveness which compensates such complexity.
  • the stanchion disclosed includes a structurally simple and effective safety system.
  • the stanchion of the invention is of the type involving the telescoping coupling of two tubes, an inner tube and an outer tube, with the latter formed by two welded segments, a lower one with a base plate which rests on the floor and an upper one with an outer threaded fillet for the manual driving screw which, by its upwards or downwards motion causes the axial displacement in the corresponding sense of the inner tube with respect to the outer tube.
  • a further complementary novel characteristic of the stanchion is that the inner tube is provided near its lower end with a pair of diametrically opposite orifices in which is placed a pin with a diameter greater than that the tube and which when mounting the inner tube on the outer one passes through a widening made for such purpose in a corresponding orifice of the baseplate, such that the inner tube can be mounted on the outer one only in a certain position in which said pin of the inner tube meets the widening of the orifice provided on the baseplate of the outer tube.
  • a further novel characteristic of the stanchion is that the inner tube, once it is fully housed in the outer one, has its bottom end deformed with a suitable tool, so that it is widened, forming a stop which prevents said inner tube from exiting the orifice of the base plate of the outer tube.
  • the inner tube once mounted in this manner on the outer tube, is free to slide in it but limited in its motion by the lower end of the draw made in the union of the two segments of the outer tube and by the stop provided by the widening made in the bottom end of the inner tube.
  • the stanchion of the invention comprises, as conventionally, two tubes (1) and (2) coupled telescopically to each other, with tube (1) being the outer one and tube (2) the inner one.
  • Outer tube (1) as conventionally, comprises two joined segments (3) and (3'), joined by a weld seam (4), with segment (3') threaded in order to assemble on it the corresponding stanchion adjustment head, so that with the head mounted on the threaded segment (3') the inner tube (2) can be raised and lowered with respect to the inner tube (1), with the latter provided with the conventional groove (5) for passage of the height adjustment pins of the inner tube (2).
  • the outer tube (3) is provided on its bottom end with the conventional baseplate (6) which has an orifice (7) for insertion of the inner tube (2), which in turn has the conventional orifices (8), a perimeter and upper flange (9) and a pair of openings (10) with a preferably quadrangular shape, without prejudice of any other suitable configuration, placed diametrically opposite.
  • the assembly is performed by inserting the inner tube (2) through the top part of the outer tube (3'), until the bottom end of the former exits though the orifice (7) of the baseplate (6) of the outer tube (3), as shown in Figure 2, at which time is inserted a pin (11) through the orifices (10) of the inner tube (2), with said pin (11) having a greater diameter than tube (2) and extending beyond its sides.
  • the inner tube (2) moves upwards until fully inserting in the outer tube (1) for which the baseplate (6) of the outer tube (3) has an orifice (7) with a size similar to that of the inner tube (2) but having diametrically opposite expansions (13) which allow the passage of the pin (11) through the orifice (7).
  • the deformation (12) of the bottom part of the inner tube (2) forms a stop against the baseplate (6) of the outer tube (1), preventing the extraction of the tube (2) through the bottom part of the stanchion, while the pin (11) provided near the bottom end of the inner tube (2) is the upper stop against the edge (14) placed under the drawing (15), thereby preventing the extraction of the tube (2) through the top of the stanchion.
