Definitions

  • the invention relates to a connecting device for the sprung connection of a drawbar or a guide bracket to the upper mass of a hand-held vibrating plate in such a way that the drawbar or the guide bracket can be pivoted with respect to the vibrating plate about a substantially horizontal pivot axis perpendicular to the direction of movement of the vibrating plate.
  • the invention is based on the object of providing a connecting device which excellently fulfills the aforementioned functional properties with a simple design which is not susceptible to faults.
  • the connecting device two pairs arranged in the direction of the pivot axis at a fixed mutual distance, each consisting of a first connecting element in the form of a rubber buffer and a second connecting element in the form of a rubber buffer which can be slid coaxially to the pivot axis and essentially has a ring which is free from play, the one connecting element of each pair being attached to the upper mass and the other connecting element the drawbar or the guide bracket is attached.
  • the guide bracket or the drawbar can be pivoted effortlessly up and down, the ring rotating around the rubber buffer and vibrations occurring in a straight line being accompanied by slight deformations of the elastic material of the rubber buffer, to which the rubber buffer does not offer any hard resistance that good soft cushioning is guaranteed.
  • the rings exert considerable forces acting on the rubber buffers at the spaced-apart fastening points of the pairs in opposite directions, to which these resist a relatively hard resistance, so that the steering force is very effective on the Upper mass and thus transferred to the vibrating plate.
  • subclaims 4 and 5 are particularly advantageous as preferred configurations, since they particularly favor the desired soft suspension in the straight running of the vibration plate and the onset of hard resistance to lateral steering movements even with a small deflection.
  • FIG. 1 is a schematic view of a vibration plate provided with the connecting device according to the invention, seen from the side,
  • Fig. 2 shows the connecting device in cross section along the Section line II-II in Fig. 1, and
  • FIG. 3 the bracket used in the connection device according to FIGS. 1 and 2 in a side view for the viewer of FIG. 3 seen from the right.
  • the vibrating plate 1 shown in side view in FIG. 1 can be guided with a U-shaped guide bracket 3 which is attached to the upper mass 1 a of the vibrating plate 1 in the manner described below.
  • a support plate 7 is rigidly attached to the upper mass 1 a at the rear end lying in the forward direction of travel, onto which a U-shaped holder 6 is fastened by means of screws 7 a in such a position that in the - In each case in a plane parallel to the direction of movement and perpendicular to the plane of the ground contact plate lb - free legs of the holder, slots 6a provided at their inward ends define a perpendicular to the normal linear direction of movement and parallel to the contact plane of the ground contact plate lb pivot axis 8 for the guide bracket 3.
  • each of the two mounting plates 10 carries one - e.g. vulcanized - to the pivot axis 8 rotationally symmetrical rubber buffer 5, which has at its free end remote from the bracket 6 a portion 9 of slightly larger diameter than its remaining length.
  • the diameter ratio is exaggerated in FIG. 2.
  • Each rubber buffer 5 is provided with a recess 5a which is essentially coaxial with its axis of symmetry and which extends inwards from the free end face adjacent to the section 9 with an enlarged diameter over part of the length of the rubber buffer 5 extends and whose diameter decreases inward from the free end face, as a result of which the rubber buffer in the area of its section 9 of larger diameter receives a particularly large degree of flexibility in the radial direction, which is considerably greater than the flexibility of the rubber buffer immediately following the metallic fastening plate 10.
  • the rubber buffers 5 are each surrounded essentially free of play by a ring 4a coaxial with the pivot axis 8, and one or the other free end of the bracket 3 is attached to the rings 4a on the circumference, e.g. welded on.
  • they each consist of the outer surface of a cup-shaped body 4.
  • the distance between the end faces of the cup-shaped body 4 is essentially determined by the fixed distance 3 of the free legs of the guide bracket 3 and the length of the rubber buffer 5 and the depth of the cup-shaped body 4 are coordinated so that at least when driving straight, the facing end edges of the cup-shaped body 4 have some distance from the vertical webs of the U-shaped bracket 6.
  • the slots 6a are necessary in order to be able to mount the rubber buffers inserted into the pot-shaped bodies 4 on the holder 6. 3, they are aligned essentially horizontally, in such a way that they extend outward in the respective vertical leg of the holder 6 from the slot base in the direction of forward travel.
  • This particular alignment of the slots 6a is due to the fact that vibration plates of the type depicted in FIG. 1 have an automatic advance caused by the vibration exciter, that is to say they only have to be moved and pulled in the opposite direction by means of the guide bracket 3, and that vibration plates frequently, e.g. B.
