Definitions

  • the invention relates to a jack with a support element on which a vertical Foldable plug-in mandrel is attached, according to the preamble of claim 1.
  • Jacks with spikes are used to lift vehicles, the preferably cylindrical receiving openings in the area of the sill or under the floor exhibit.
  • an insertion mandrel arranged on the support element is inserted into the insertion opening pushed on the vehicle. This is a non-positive and positive connection made between jack and vehicle.
  • the formation of the attacks on Insert mandrel is realized in different ways.
  • the thickened end of the insertion mandrel serves as a stop.
  • a Insert mandrel according to DE 38 16 054 C2 serves as a receiving part for the insert mandrel as a stop.
  • This training is also associated with a high manufacturing cost and an increased weight.
  • a deferred serves Socket as a stop to achieve the desired insertion depth of the Insert pin. The disadvantage of this is that this socket is easily lost can. If this is to be excluded, there is an additional step and additional material for connecting the pushed-on socket with the plug-in mandrel required.
  • the invention has for its object in a generic jack to provide a stop on the plug-in mandrel that is light in weight and is fixed securely and reliably in a simple manner.
  • the Insertion depth of the insertion pin limiting stop is not only easy and simple and is securely connected to the spike, but that it is through its Training as an intermediate layer between the mandrel and support element also advantageous the task takes on a permanent smooth movement of the folding movement between Insert mandrel and support element to ensure wear and tear between the insertion mandrel and the support element.
  • a Articulated jack described and shown in Fig. 1.
  • the subject of the invention can be used in the same way for other types of jacks.
  • the articulated jack shown in Fig. 1 has a leg 1 and a support arm 2, which are pivotally connected to one another by means of a joint 3 are.
  • a threaded spindle 4 at the end of which a hand crank 5 is arranged, connects support leg 1 and support arm 2 via further joints 6, 7.
  • the support arm 2 arranged hinge 6 is connected to a pivot bearing. That at the top of the Main leg 1 arranged joint 7 includes a threaded spindle 4 receiving Motion nut.
  • Another joint 8 is rotatable at the lower end of the supporting leg 1 Mounted foot 9, which ultimately stands on the floor 10.
  • Movement between the support arm 2 and Mainstay 1 leads to the front end of the support arm 2 relative to the Floor 10 raises or lowers.
  • One arranged at this front end of the support arm 2 Support element that in a predetermined manner with the vehicle to be lifted is connected or carries this vehicle in a suitable manner, then leads to Raising or lowering the vehicle against the ground 10.
  • a vertically foldable insertion pin 11 In the generic jack is as a support element at the front end of the Support arm 2 arranged a vertically foldable insertion pin 11. That spike 11 is inserted into a corresponding opening, not shown, of the vehicle. This ensures that the jack with a positive fit in the stroke direction connected to the vehicle.
  • the vertical foldability of the insertion pin 11 is via a further horizontally arranged joint 12 designed as a hollow axis manufactured.
  • the insertion pin 11 is designed as a hollow pin in the front region and is made by rolling a sheet. This sheet is in the rear area not rolled up into a hollow mandrel, but forms fastening tabs 13. Bores arranged in these fastening tabs 13 become the joint 12 forming hollow rivet 14 out. Stops 15 on the mounting tab 13 serve in cooperation with one attached to the front end of the support arm 2 Transverse wall 16 to limit the upward pivoting movement of the insertion pin 11 is.
  • a stop 17 is provided on the insertion pin 11. That attack 17 is annular in its front region as the insertion pin 11 Sleeve 18 formed and goes over a back part 19 in two laterally arranged Rag 20 over.
  • These tabs 20 are like the mounting tabs 13 of the Insert pin 11, provided with holes through which the hollow rivet 14 of the joint 12 extends. The tabs 20 thus lie between the fastening tabs 13 of the insertion pin 11 and the side walls 21 of the support arm 2. After a lateral Crimping the hollow rivet 14 on the outer sides of the side walls 21 of the Support arm 2, the joint 12 is completed.
  • a label or marking can be applied on the back part 19 of the stop 17, as shown in Fig. 2, as shown in Fig. 2, a label or marking can be applied.
  • Fig. 2 is an arrow on this Back part 19 attached, which should give the indication that the insertion pin 11 is complete up to the stop 17 in the receiving opening of the vehicle to be lifted is to be inserted.
  • the stop 17, consisting of sleeve 18, back part 19 and tab 20, is in the Embodiment made in one piece from a suitable plastic.
