Definitions

  • the invention relates to a crank knob, in particular for window cranks of vehicles, which can be rotatably arranged on the crank pin of a crank arm and has a trigger lock which can be snapped into a breakthrough of the crank pin and which has spring arms formed at one end with latching cams and at the other end integrally with a flange.
  • the German utility model 74 28 675 describes a crank with a crank knob which is mounted on the crank pin in such a way that the points at risk of wear are secured against twisting, thus preventing material abrasion which impairs the functionality of the crank knob.
  • the crank knob has an open design and is partially covered by the trigger lock, which is secured against twisting.
  • the invention has for its object to provide a crank knob in a closed design, which is equipped with a particularly advantageous trigger lock according to the aforementioned utility model and its structure fully meets the standard for the design requirements of objects in motor vehicles (ECE standard 21) becomes.
  • the invention provides that the crank knob from a plug-on to the crank pin, at one end overlapped by the flange of the trigger lock socket, a cross-over the flange and concentrically enclosing the socket and a cap anchored to the socket, the cap embedding crank button jacket, which is made of a much softer material than the other crank button parts and has a hardness of max. 5o Shore A.
  • a crank knob designed in this way according to the invention fully meets the ECE regulations in that it has a relatively soft jacket and an inner core which can be designed with soft radii.
  • crank button jacket to the inner sleeve can be done by unbuttoning, but preferably in that the crank button jacket is anchored to the sleeve and the cap by extrusion coating.
  • the rotatability of the crank button casing with bushing on the crank pin is fully preserved by the attached cap; because the trigger lock is protected against over-splashing by the cap.
  • the bushing has on its outer lateral surface in an annular arrangement radially outwardly directed webs which are completely embedded in the spherical button jacket.
  • the webs create a clawing of the jacket material with the socket.
  • the webs can serve as a stop for the cap that is plugged onto the socket, in that the open end of the cap is supported against the webs.
  • the crank button is made exclusively of plastic.
  • the bushing and the cap can preferably be made of PPN, the trigger lock preferably made of POM and the crank button jacket made of PVC 50 -5 Shore A.
  • the crank knob according to the invention has a four-part structure, the three-part core can be preassembled quickly and simply by simply plugging it together and the jacket can be formed inexpensively by extrusion coating with a good surface finish. It is also quick and easy to assemble by means of plug-in assembly, has a permanently functional trigger lock and is exposed to only negligible wear due to the radial locking of the trigger lock. The crank knob thus optimally fulfills the ECE regulations.
  • the crank knob consists of a bushing 1, a trigger lock 2, a cap 3 and a crank knob jacket 4.
  • the bushing opening 5 is designed in diameter to receive a crank pin. It has integrally formed webs 6 on its outer jacket in an annular arrangement, which have a hook-shaped design and serve once for clawing in the crank button jacket 4 and once as a stop for the open front end of the cap 3.
  • the trigger lock 2 has a flange 9 which is supported on the upper end face of the bushing 1 and on the underside of which spring arms 7 are formed, the free ends of which have locking cams 8.
  • the crank button is secured to a crank pin against pulling out.
  • the opening provided in the crank pin, not shown, which interacts with the spring arms 7, is expediently square and the spring arms 7 are adapted to this design.
  • the spring arms 7 also secure the trigger lock 2 against rotation. This means that when the crank knob is installed, only parts 1, 3 and 4 can rotate around the crank pin, while the trigger lock 2 cannot rotate. Abrasion wear is largely avoided.
  • the flange 9 of the trigger lock 2 has on the outside a centrally formed conical cam 10 which is supported on the bottom of the cap 3.
  • the bottom 3 can have a concave indentation in which the cam 10 engages for perfect centering.
  • the crank knob has a four-part structure as can be seen from the drawing, the three-part core being joined by plugging, after which the crank knob jacket 4 is formed by extrusion-coating the three-part core with a relatively soft plastic material.
