Definitions

  • the invention relates to a vibration-damped handle according to the preamble of patent claim 1.
  • Handles on the drawbars of soil compacting devices hand-guided by means of the drawbar usually have two side parts which extend symmetrically from the drawbar to the side and towards the operator, between the ends of which the actual handle part extends, which is so wide that the operator can use both with the two parts Hands can be taken side by side.
  • the actual handle part is a tube, which is connected at its ends via a coaxial rubber element to one or the other side part of the handle and at its ends with radial play in one with the respective side part rigidly connected collar engages, which limits the possibility of movement of the handle bar in the radial direction with respect to the side parts.
  • the cushioning of a handle is more effective the larger the cushioned mass and the smaller the cushioning spring force.
  • the latter must not be too small to achieve sufficient managers, so that the largest possible cushioned mass is desirable.
  • the invention has for its object a vibration-damped To design the handle so that the sprung part has as large a mass as possible that parts necessary for the design of the handle are included in the sprung mass.
  • the side parts which are essential for this are included in the sprung mass, because the damping elements are inserted between the oscillating plates forming these side parts and the drawbar close to the latter.
  • the subclaims relate to preferred embodiments of the handle according to claim 1.
  • the drawing shows an embodiment of the handle according to the invention in a perspective view.
  • the handle consists of a connection part 1 and a handle part 6 which can be swiveled relative to it.
  • the connecting part 1 has two mutually parallel elongated connecting plates 2, which in the exemplary embodiment are rigidly connected to the shaft 3a on both sides of an actuating shaft 3a, which is rotatably mounted on the end of the drawbar 3 at the end of an actuating element (not shown in more detail) for the vibration exciter of the vibration device, which is also not shown in the drawing . If it is not important to use the handle for the drive control of the compactor at the same time, the connecting plates 2 can also be connected directly to the drawbar 3.
  • the handle part 6 has two oscillating plates 8, which are rigidly connected to one another via a handle 7 and between them accommodate the connecting plates 2 at a distance from them.
  • the oscillating plates 8 and the connecting plates 2 are with each pair of plates by means of two rubber elements 4 arranged at a mutual distance at the ends of the elongated plates 2, 8 and connected to one another so as to be oscillatable.
  • connection plates 2 and the rocking plates 8 parallel to each other also results in a slim handle with good functionality with regard to the operability of the device and a beautiful appearance.
