Definitions

  • the locking body spring-loaded parallel to the axis of the joint is stored. This opens up the possibility that To select the actuation direction parallel to the axis instead of radial, so that the operating handle, like a knob, a handle or the like, are located directly in the area of the joint can and not in the direction of the spar or even sideways must extend.
  • This surprisingly simple measure represents a significant one Improvement that allows it to be a particularly simple one and also extremely reliable and torque-resistant To reach the design of the joint.
  • the direction of actuation can be configured accordingly Moldings realize a large number of blocking surfaces, each with tight tolerances with corresponding molded body recesses or angular position recesses interact can.
  • the molded body can preferably be subjected to pressure be, in its main direction of extension is practically under shear stress, which he is extremely good can take up after the molded body recess and the angular position recess can be performed adjacent to each other.
  • This constructive solution enables it to be compared low material thicknesses, so that the invention Joint can build compact and despite its Stiffness and operational safety is comparatively easy.
  • a compression spring is used as the spring element can be used. This allows the actuation path for the molded body and the locking member by plant limit the spring turns to each other.
  • a handle can both a pull knob and a corresponding handle are used are, for reasons of operational security the Use of a tension element is preferred.
  • the is preferred Actuation knob then about 180 ° or for example by one full rotation rotated from the release position to the Locked position in the spring-loaded state of the spring-loaded Arresting member.
  • the pitch of the corresponding thread can be chosen so that the spring force automatically sets the rebound condition.
  • the joint according to the invention is self-locking to a certain extent.
  • the provided thread run flat for this. If the Actuation knob there, i.e. in the flat section of the thread, supported, automatic rebound is prevented, so that the ladder can pivot freely around the joint is.
  • the illustrated conductor 10 has three joints on each side of the spar on, of which the joints 12, 14 and 16 are clearly visible.
  • Spar sections 18, 20 extend at the end of the joints, 22 and 24.
  • Each joint has two joint parts 26 and 28, which end in connecting pieces that extend into the flat cross-tubular Spar sections 18 to 24 extend into it.
  • the connecting pieces extend in a manner known per se up to rungs 30, optionally in addition to further stiffening fingers of the connecting piece the rungs reach over to the side.
  • Each joint part 26 and 28 is in the manner of a circular disk formed with connecting piece, for which purpose, for example, on Fig. 2 and 3 is to be referred.
  • Each joint 12 to 16 has one Knob 34 on the side, so next to the spar extends outside and in the illustrated embodiment is designed as a pull or screw knob.
  • the joint is Can be actuated about a hinge axis 36, two hinge parts 26 and 28 each have spar connecting pieces 38 and 40 and in Are essentially circular disk-shaped.
  • the hinge parts 26 and 28 are hinged together.
  • a molded body extends around the bearing journal 44, with which the joint parts 26 and 28 can be fixed to one another are, in each of the selected locking positions.
  • In the embodiments according to Figures 2 and 3 are eight locking positions provided that are evenly distributed so that each Rest position extends at an angle of 45 ° to the neighboring.
  • Both joint parts 26 and 28 can also be used as ends of the spar are considered after they are connected to their connecting pieces, for example by rivets 46, fixed to the associated spar section are connected.
  • the molded body 44 is movable in the direction of the hinge axis guided. In the illustrated embodiment, it has the form of a flat cuboid with a square plan and extends symmetrical to the journal 42. Between the is the upper end of the journal 42 and the guide body a compression spring 46 is added, which follows the molded body 44 presses down into the locked position. Between the compression spring 46 and the molded body or the knob 34 extends a sleeve 48. These elements together form the locking member 50, which allows between the release position and the to switch the locked position of the molded body 44.
  • the angular position recess 54 can be formed.
  • it is shaped like an 8-pointed star, so that the molded body 44 is spaced 45 ° apart Can bring angular positions there.
  • any other configurations of molded body 44, angular position recess 54 and molded body recess 52 possible are without leaving the scope of the invention.
  • the shaped body 44 can be essentially rod-shaped and the angular position recess 54 can then have a plurality of recesses matching this rod, that overlap each other and each in the desired Extend angles to each other.
  • FIG. 6a shows the shaped body 44 in a top view.
  • the comparison with FIG. 6b shows that it is in a total of eight different angular positions in the one there Angle position recess 54 fits. It is from the molded body recess 52 of the joint part 28 carried along according to FIG. 6c.
