Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a generic device for unfolding a pontoon unit to form a floating bridge in which two inner and two outer pontoons are connected with joints so that they can be unfolded in a w-shape, the two in the folded state
  • Inner pontoons connected to an upper central joint and the two outer pontoons are connected to the adjacent inner pontons by a lower joint each.
  • the joint below is formed from two pegs that are arranged in the adjacent corners of the inner and outer pontoon.
  • the pins are rotatably connected by a cantilevered lever, the cantilevered ends of the lever being limited in their freedom of movement by stops.
  • the end of the lever facing the outer pontoon is connected to a tension spring.
  • the outer pontoons of the w-shaped foldable pontoon unit are unfolded by the tension springs against the buoyancy force acting on them, which is why no special help is required to unfold them.
  • the folding of the pontoon unit can be accomplished without the aid of additional equipment in the form of push boats or the like and without excessive effort, in such a way that one in its between a free end of the tension spring and a connection point on the outer pontoon Length variable connector is turned on.
  • the connector can be designed as a hydraulic piston-cylinder unit in which the piston or the cylinder is connected to the free end of the spring and the cylinder or the piston is connected to the outer pontoon.
  • the object of the invention is to improve a generic device so that the length of the space under the pontoon deck of the outer pontoon can be dimensioned as short as possible in order to limit a weakening of the deck structure to a minimum without other construction parameters
  • Known construction, such as maximum tension spring dimension and pontoon deck protrusion to change, in addition, a lower tension spring force and thus lighter design of the device is sought.
  • the lever therefore has only a short projecting part on the outer pontoon side.
  • the free space under the pontoon deck can therefore be dimensioned shorter than in the known device.
  • this free space is only slightly longer than the overhanging part of the lever.
  • the "extension" of the overhanging part, namely the rocker arm, is then angled away from the lever outside the free space.
  • the device thus makes it possible to make the length of the free space under the pontoon deck smaller, which makes it possible to better stiffen the overhanging construction of the pontoon deck, so that larger loads can be absorbed by the projecting pontoon deck.
  • the pivotable rocker arm arranged at the end of the lever, at the end of which the known tension spring engages, has a milled stop, with which the rocker arm rests on the projecting part of the lever in the folded state of the pontoon unit and thereby a longer lever arm forms.
  • the tension spring force now acts on this longer lever arm.
  • the longer lever arm on the outer pontoon side also offers the possibility of arranging the end stop for the lever on the pontoon side wall further from the pivot point of the lever, as a result of which the contact force is reduced.
  • FIG. 1 shows sections of an inner pontoon 1 and an outer pontoon 2 hinged to it, of a pontoon unit for one consisting of two inner and two outer pontoons Floating bridge in the folded state. As mentioned above, the entire pontoons have not been shown. It should only be mentioned that a central joint is arranged at the (not shown) upper end of the inner pontons that connects the inner pontons of a pontoon unit.
  • the projecting part 3b of the lever 3 has at its end a pivotable rocker arm 7, which in the folded state of the pontoon unit (according to FIG. 1) strikes with its stop 8 at the end of the projecting part 3b of the lever 3 and thus forms an extended lever arm.
  • the tension spring 9 arranged on the rocker arm 7 is tensioned.
  • Fig. 2 shows sections of the inner pontoon 1 and outer pontoon 2 in the unfolded state of the pontoon unit.
  • the lever 3 with its overhanging parts 3a, 3b is located within the free spaces 10, 11 under the pontoon decks 13.
  • the relatively short overhanging part 3b can be seen in the correspondingly short free space 11.
  • the sum of the lengths of the free spaces 10, 11 is otherwise only slightly larger than the total length of the lever 3, ie based on the known construction, the length of the free space 11 of the outer pontoon 2 is significantly shorter.
  • the rocker arm 7 is angled from the overhanging part 3b of the lever 3 at the boundary 12 of the free space 11.
  • the tension spring 9 arranged on the rocker arm 7 is relaxed.
