Definitions

  • the invention relates to a support arm for movable structures according to the preamble of the claim.
  • the invention has for its object to provide such support arms in which an automatic display takes place; when the stability of the construction is reduced to a predetermined value.
  • the movement mechanism has a movement space between a position in which the foot is raised and another position in which it is lowered, and in that a spring pushes the movement mechanism into the position in which the foot is raised, an alarm switch being actuated.
  • a reduced load triggers the actuation of an alarm switch when it has reached a point in which the movable construction no longer rests on the support arm in the desired manner.
  • the permissible extent of the load reduction before triggering can be adjusted via the spring force.
  • FIG. 1 shows, partly in section, part of a movable structure with a support arm according to the invention.
  • a support arm is suspended from the construction to be supported in such a way that a foot 1 provided at the free end of the arm can be raised and lowered in relation to the contact surface.
  • the foot 1 is thus pivotably suspended in the supporting arm to allow the contact surface of the foot rests irrespective of the inclination of the support surface and / or of the supporting arm against the support surface.
  • the support arm is suspended in a part 2 of the movable structure in such a way that it can be pivoted up and down by means of a movement mechanism 3 which engages between the structure and the support arm until the foot 1 presses against the bearing surface.
  • the movement mechanism 3 shown in the present case as a cylinder-piston mechanism, has a movement space at one of its engagement points - in the embodiment shown in the engagement point on the support arm - the end 5 of the piston rod being axially along a slot formed in a projection provided on the support arm 4 is displaceable.
  • the end 5 of the piston rod bears against a contact arm 6 which is biased by a spring.
  • a spring 8 - in the present case a number of disc springs - is compressed between a sleeve provided on the contact arm and a stop 7 in the projection of the support arm such that the contact arm 6 is pressed against the piston rod.
  • the spring 8 then strives to hold the end of the piston rod 5 at the end of the slot 4, as shown in the figure.
  • the pressure exerted by the support arm against the bearing surface has a given value for all support arms of the structure. If this pressure changes with a or several support arms reduced, this is a sign that the movable structure is no longer stable.
  • the spring 8 When the holding pressure for the support arm shown drops to a set value determined by the spring 8, the spring 8 tries to push the foot further down against the bearing surface, causing the projection of the support arm with the slot 4 to be in proportion to move the end 5 of the piston rod so that the contact arm 6 no longer presses against the electrical switch 9.
  • the switch 9 therefore emits a signal which warns the operator of the movable structure and / or possibly prevents further movement of the structure.
  • the arrangement of the alarm contact shown can of course be changed.
  • the contact arm can e.g. instead of the axially displaceable piston rod shown, a rocker arm.
  • the essential feature of the invention is that the movement mechanism 3 has a movement space in the lowering direction of the foot against a corresponding spring force, and that the displacements of the movement mechanism in this movement space are controlled in a suitable manner.
