Definitions

  • the invention relates to a lifting stand for a trampoline.
  • the lifting roller stand consists essentially of a stator part, comprising a first, extending in the horizontal direction metallic support, at the longitudinal ends of each a roller is mounted and a fixed to the upper side, extending in the vertical direction second metallic tubular support.
  • a lever is attached by means of a hinge, wherein the joint divides the lever into two lever arms.
  • a handle for actuating the lever is provided by an operator.
  • an adapter for attaching the lever to the trampoline is in the form of a cylindrical tube piece which can be inserted into a hollow cylindrical receptacle on the trampoline.
  • the trampoline can be raised or lowered by pivoting the lever. In a lower and upper limit position while the lever can be secured in position by a securing bolt on the vertical support.
  • An advantage of this Heberollschreibr is that this has a very robust design and its operation is easy to carry out even by unskilled personnel.
  • the disadvantage is that for the operator, the actuation of the lever when lifting the trampoline with an undesirably high amount of force is connected, since the pressing takes place against the entire weight of the trampoline.
  • a lowering of the trampoline by means of the lever is associated with dangers, since then the entire weight of the trampoline rests on the lever.
  • the invention has for its object to provide a lifting jack stand of the type mentioned for trampolines, which can be operated with high safety standard easy and with little effort.
  • the lifting stand for a trampoline comprises a stand part mounted on rollers with a guide.
  • a fixable on the trampoline guide element is arranged height adjustable.
  • the guide has an adapter for fixing on the trampoline and an actuating element for height adjustment of the guide element.
  • a hydraulic unit is provided as a means for height adjustment.
  • the actuator for actuating the hydraulic unit is a pedal.
  • a significant advantage of the lifting roller stand according to the invention consists in the fact that the infeed and extension of the guide element in the guide and thus the implementation of the height adjustment of the lifting roller stand can also be performed easily and quickly by inexperienced persons and even children. It is particularly advantageous that there is no security risk in the foot operation of the foot lever. In particular, there is no risk of pinching the limbs of the respective operator in the operation of the foot pedal. Since thus risk of injury to the operator can be excluded with high security in the operation of the pedal, the lifting tool according to the invention meets a very high safety standard. Another significant advantage of the invention is that lifting and lowering of a trampoline can be performed with little effort by the built-in Heberollschreibr hydraulic unit.
  • Another advantage of the hydraulic unit used is that with this not only a simple retraction and extension of the guide element in the guide for carrying out the height adjustment is guaranteed. Rather, it is achieved alone with the hydraulic unit, without the use of further mechanical latching means that a set height position of the guide element is securely held in the guide.
  • the hydraulic unit has damping properties.
  • a trampoline To store a trampoline, two lifting racks are required, which are attached to opposite sides of the trampoline.
  • the lifting stand is designed in such a way that it can be optionally attached to one of the sides of the trampoline. Thus, only one design of the lifting roller stand for the storage of a trampoline is needed. Due to the height adjustability of the lifting roller stand, the trampoline can be stored at different heights on the lifting roller stands.
  • a lower sole position is dimensioned so that the total height of the trampoline mounted on the height of the lifting columns is smaller than the heights of doors in buildings, so that the trampoline can be pushed past the height of the lifting columns through such door openings.
