Definitions

  • the invention relates to a jack according to the preamble of claim 1.
  • Load-bearing parts of jacks are pivotally connected to one another by joints.
  • the load-bearing parts of the jack are usually designed as cross-sectionally U-shaped profiles with lateral profile legs.
  • Other load-bearing parts such as the jack head or jack foot, are designed with sheet metal tabs that protrude laterally.
  • the connection of these load-bearing parts takes place in such a way that the profile legs or the laterally protruding flaps overlap in the area of the joints and are provided with bores; they are then connected by means of axes arranged in the bores.
  • DE-OS 2 231 526 shows such joints in which bolts are used as axes. In the design according to EP 0 332 565 A1, the axes are formed by neckings.
  • the profile legs or the sheet metal tabs must be very strong, especially at their ends, that is to say in the area of the joints, since there is a risk, particularly in the case of bending stress, that these corners are bent, which affects the stability of the entire jack. This leads to a corresponding increase in weight.
  • the invention has for its object to reduce the weight of known jacks, but also the risk of kinking the profile legs.
  • the design of a jack according to the invention means that the weight of the jack can not only be reduced with the same load-bearing capacity, although the stability is increased. Also the stability of the load bearing provided with beads
  • Parts of the jack are also increased.
  • FIG. 3 is a 90 ° offset section to FIG. 2,
  • FIG. 5 is a 90 ° offset section to FIG. 4,
  • FIG. 6 is an enlarged view of the formation of the joint between the jack foot and the support leg, the joint being designed as neckings of the jack foot that engage in holes in the support leg,
  • FIG. 7 is a 90 ° offset section to FIG. 6.
  • jacks have articulated support parts that connect the jack foot and the support element to one another in a manner that allows them to move in height.
  • the supporting parts which are connected to one another in an articulated manner, must be able to support the vehicle weight. It is therefore essential that these joints function safely and consistently.
  • the articulated jack shown in Fig. 1 represents only one type. However, the invention is also suitable for all other types of jack that have the prerequisite according to the preamble of claim 1.
  • Articulated jacks according to FIG. 1 have jack feet 1, supporting leg 2, support arm 3 and support plate 4 as supporting parts. All of these load-bearing parts are articulated to one another via joints 5, 6, 7.
  • a threaded spindle 10 is connected to the support leg 2 and the support arm 3, which enables the support arm 3 to be pivoted upwards relative to the support leg 2 via a threaded nut, which leads to the lifting of the support plate 4 relative to the jack foot 1.
  • the threaded spindle 10 is driven via a hand crank 11.
  • the jack foot 1 has a base 12 with a base 12 with sheet metal tabs 13 standing up laterally.
  • the support leg 2 is designed as a U-shaped profile formed, which also has a bottom 14 and side profile legs 15. The same applies to the support arm 3 with its base 16 and the profile legs 17.
  • the joint according to the invention is suitable for connecting the support arm 3 to the support leg 2 or the support leg 2 to the jack foot 1.
  • connection of the jack foot 1 to the supporting leg 2 is shown enlarged.
  • 2 to 5 is used to form the joint 5 on both sides riveted bolt 18, which penetrates holes in the upstanding tabs 13 of the jack foot 1 and in the profile legs 15 of the supporting leg 2.
  • beads 19 punched out on both sides are directed inwards from the floor 12 of the jack foot 1. These beads are arranged within the profile leg 15 of the supporting leg 2 close to them. Between sheet metal tab 13 of the jack foot 1, profile leg 15 of the supporting leg 2 and beads 19 there is only a game required for the pivoting movement. Good guidance of the ends 20 of the profile legs 15 is thereby achieved. The beads 19 extend underneath the pin 18. The pin 18 can thus be supported on the beads 19, if necessary.
  • FIGS. 4 and 5 corresponds approximately to the formation according to FIGS. 2 and 3.
  • the beads 21 formed out of the bottom 12 of the jack foot 1 are separated from the bottom 12 on only one side. On the other hand, they are firmly connected to it.
  • the hinge 5 is formed by the fact that inward protrusions 22 from the upstanding sheet lugs 13 of the jack foot 1 engage in bores 23 of the profile legs 15 of the supporting leg 2.
  • the position fixing of the ends 20 of the profile legs 15 is formed by inwardly projecting tabs 24. These tabs 24, like the beads 19, 21, are punched out of the base 12 of the jack foot 1 and then bent up.

Abstract

L'invention concerne un cric comportant des parties portantes se présentant sous forme de profilés de section transversale en U à branches latérales (15,17) ou d'éléments à languettes en tôle (13) surélevées latéralement et interconnectées de manière à pivoter par l'intermédiaire de joints articulés, de sorte que les branches latérales profilées (15,17) et/ou les languettes en tôle (13) surélevées se chevauchent dans la zone des joints articulés (5,6) et que des pivots traversent des alésages dans les branches latérales profilées (15,17) ou dans les languettes en tôle (13) surélevées. L'invention vise à réduire le poids des branches profilées (15,17), ainsi que le risque qu'elles ne se rompent en pliant. A cet effet, le fond du profilé en U ou de l'élément, qui enserre l'autre profilé ou élément par ses branches profilées (15) ou ses languettes en tôle (13), est muni de collets (19,21) ou de languettes (24) faisant saillie vers l'intérieur, qui se trouvent à l'intérieur, mais à proximité des branches profilées (15,17) ou des languettes en tôle de l'autre profilé ou élément.
