Definitions

  • the present invention relates to a cage nut.
  • Cage nuts such as are known for example from US publications US 2004/0136804 Al, US 2004/0091333 Al, US 2004/0013492 Al or US 2004/0228700 Al, each comprising a nut having a cylindrical nut body with a coaxial bore with a Internal thread on which a plate is fixed with rectangular end pieces, which is mounted by means of these rectangular end pieces floating in a cage.
  • the rectangular end pieces are usually formed so large that they almost completely surround the nut body, so that the impression of a mother with a rectangular body and with only a small cylindrical approach.
  • the associated cages are formed from a multiply bent plate, which surrounds the nut almost completely in such a way that only two side surfaces and above and below a circular opening remain open.
  • the cage consists only of a bent in the form of a very flat U sheet whose bottom surface has a large circular opening, while the flat legs of the U are provided with horizontal slot-shaped openings in which the rectangular end pieces of the nut are added.
  • the rectangular end pieces which are attached to the nut bodies, here do not extend along the channel formed by the U-shaped folded sheet, but they are inserted through slots in the legs of the U-shaped cage.
  • the cage is sufficient in the form of a flat U, which already significantly material is saved and the risk of sticking nut and cage during the painting process is significantly reduced.
  • the size of the rectangular end pieces can be significantly reduced, whereby further savings in material and weight are possible.
  • the plate, which must be fastened to the nut bodies, according to the invention can also be made substantially thinner than in the prior art. This also further material and weight savings are possible.
  • the slot-shaped openings are provided on their longitudinal sides with elevations.
  • the electrical contact between the cage and the nut is reduced, which results in an electrophoretic paint finish in that the nut, and in particular the thread borne by the nut, attracts considerably less paint.
  • the elevations as triangular teeth. This maximizes electrical resistance between the cage and the nut.
  • the slot-shaped openings with elevations only on their upper sides and to provide further elevations on the bottom surface of the cage.
  • the slot-shaped openings can then be designed such that in the region of the openings the bottom surface remains flat and does not have to be bent at all, which further facilitates the production of the cage.
  • the elevations on the slot-shaped openings are triangular teeth.
  • Figure 1 is a three-dimensional view of a cage nut according to the invention.
  • Figure 2 is a three-dimensional view of the cage of Figure 1 alone.
  • Figure 1 shows a cage nut 10 according to the invention, comprising a cylindrical nut body 12 with a coaxial bore 14 with an internal thread, to which a plate 16 with rectangular end pieces 18, 20 is attached.
  • the plate 16 can be made considerably thinner than in the prior art and also the rectangular end pieces 18, 20 can be made much narrower.
  • the connection between the nut body 12 and the plate 16 can be made arbitrarily, for example by clinching, welding or a deformation process.
  • the cage nut With the rectangular end pieces 18, 20, the cage nut is received in the cage 30 and stored floating therein.
  • the cage 30 consists of a very thin, in the form of a very wide and very flat U bent sheet, the very short legs 32, 34 of the U are bent upwards and therebetween a bottom surface 36 is arranged. In the center of the bottom surface 36, a circular opening 38 is provided through which later of the cage nut 10 male external thread carrier can occur.
  • the opening 38 is surrounded by two elevations 40, 42 which surround the opening 38 like niksektorenförtnige braces concentric, these elevations 40, 42 are arranged only in the vicinity of the legs 32, 34 of the U-shaped plate.
  • nubs 44 may be provided with approximately the same diameter when the corresponding cage nut according to the invention for riveting to a workpiece (instead of welding) is provided.
  • slots 46, 48 are provided in the legs 32, 34 of the cage. These slots 46, 48 are made by punching before the bending of the legs 32, 34 of the U-shaped cage 30. The bottom 36 of the cage 30 therefore extends somewhat further outward in the region of the slots 46, 48.
  • the slot 46 facing the viewer in the present illustration is shorter in the longitudinal direction than the slot 48 facing away from the observer.
  • Both slots 46, 48 are provided with 3 triangular teeth 50 at their upper edge. These serve, as well as the projections 40, 42 to, on the one hand to prevent sticking of the nut in the cage 30 after painting and on the other hand, in the case of Electrophoresis paint to form a high electrical resistance between the cage 30 and the mother so that as little paint in the internal thread in the bore 14 is deposited.
  • circular sector-shaped elevations 40, 42 may also be provided at the lower edge of the slots 46, 48 corresponding, for example, triangular teeth as spacers and to increase the electrical resistance between the cage and nut.
  • the present invention is very advantageous over the prior art because it can be made using standardized components with components that are very easy to manufacture (inherently inexpensive). Nevertheless, the cage nut according to the invention meets all the requirements that are placed on the previously known in the art cage nuts. It allows a minimal contact surface between cage and nut, whereby a bonding of cage and nut during painting, especially in Elektrophoreselacktechnik is ensured. Due to the high electrical resistance, which is formed by the elevations 40, 42 and 50 between cage and nut body, only the cage 30 is charged in the electrophoresis, but not the mother itself. This avoids that the internal thread of the bore 14 is clogged with paint.
  • the nut according to the invention is also easily replaceable in case of later repair work.
  • different cage nuts of the invention can be made of standard parts and very simple parts.
  • the for the cage nut according to the invention The required manufacturing process involves only assembly, whereas in the prior art, assembly and deformation (cage) operations must cooperate to produce a prior art retainer nut.
  • the cage nut according to the invention can be produced with very little investment, at the same time, the cage nut according to the invention can be produced with significantly greater productivity. In this way, the cage nut according to the invention is considerably less expensive than the products according to the prior art.
  • the cage nut according to the invention can be made of a standard nut, which is connected to a metal plate by clinching, welding or other method, wherein the metal plate is then received in a cage made of very thin material.
  • the nut and plate 16 are designed so that they absorb all the structural forces of the compound, while the cage 30 holds only the nut and the plate 16 in position before a corresponding external thread carrier, such as a screw is installed.
  • a corresponding external thread carrier such as a screw is installed.
  • the cage 30 itself can be made of extremely thin sheet metal material, it is possible to simply press through the metal strips of the legs 32, 34 above the slots 46, 48 by means of a pair of pliers. Nut 12 and plate 16 can then be removed and replaced, after which the sheet metal strip above the slots 46, 48 can be bent back to its original position, so that the new nut 12 with the new plate 16 is again held floating by the restored cage 30 , In this way, repair of a vehicle manufactured using the cage nut according to the invention is considerably easier than in the case in which cage nuts according to the prior art are used. With the described method, the nut can be replaced, wherein the cage 30 can be obtained, and also fulfills its function after bending back the researcher strip in its entirety.
  • the elevations 40, 42 and 50 according to the invention are formed exclusively by the cage 30.
  • such elevations must be provided in special places of both the cage and the nut. These digits also depend on the respective customer-specific application.
  • the number and position of the effective protuberances, which serve as spacers between nut and cage depends on the random position between nut and cage at the time of painting.
  • the elevations acting as spacers are all on the cage. The Bumps never change, and this ensures that the nut 12 and the plate 16 always have the least possible contact with the cage 30, regardless of the respective position of the nut in the cage 30th
  • the cage nut according to the invention for the first time the method described above for replacing mother and plate 16 available in the mother and plate 16 can be changed and then the original cage 30 can be used without much effort and continue to fulfill its function.
  • a cage nut which can be manufactured with considerably less material and labor, has a lower weight and offers significant advantages in the electrophoretic paint and required repairs against the cage nuts of the prior art.
