Definitions

  • the invention relates to a crank rod, an eyelet and a crank drive for awnings.
  • Crank rods are e.g. described in US-A-2 143 348 or DE-A-36 23 612 and are used to actuate eyelets in awnings.
  • the conventional eyelet usually has an oval shape, which on the one hand results in an uneven transmission of the torque from the crank rod to the eyelet and on the other hand the wear of certain parts of the eyelet.
  • the non-uniform transmission of the torque also has the consequence that the crank rod has dead center positions during its operation, which is also undesirable.
  • the invention has for its object to remedy this situation and to further develop the crank rod without undue design effort so that proper drive of the eyelet is possible even when it is
  • the axis of rotation does not coincide with the longitudinal central axis of the crank rod, but encloses an angle of up to 60 °.
  • Another object of the invention is to propose a corresponding eyelet and a corresponding crank drive for awnings.
  • crank rod is designed according to the features of claim 1, so that it can be supported on the inner circumference of the eyelet at at least two opposite points, even if the angle that the Axis of the crank rod with the axis of rotation of the eyelet is defined up to 60 °.
  • This is essentially achieved in that the section of the hook extending transversely to the longitudinal axis of the crank rod is so large that the above requirement is practically always fulfilled.
  • the eyelet provided for a crank rod has the special feature that it has two approximately frusto-conical, coaxially arranged and with its tapered ends opening into the common opening with mating surfaces with working parts which can be brought into operative connection with the section of the hook crossing the opening .
  • a particularly useful embodiment provides that the length of the section corresponds approximately to the maximum outer diameter of the eyelet.
  • the eyelet is, so to speak, independent of the inner dimensions of the eyelet, which is regularly oval, but can also have a circular inner contour.
  • an expedient embodiment of the invention provides that the free end of the section has an angled portion, a thickened portion or an enlarged diameter.
  • the crank bar can only be released from the eyelet if it is lifted and threaded out of the eyelet.
  • an expedient embodiment of the invention provides that the free end of the section can be inserted through the eyelet.
  • a further expedient embodiment of the invention provides that the section is connected to the crank rod via a straight or curved section.
  • the length of the straight or arcuate section can be greater than the thickness of the ring-like eyelet.
  • FIG. 5 reveals an eye 10 for awnings that cooperates operationally with a hook 30 and has a crank rod 32 that can be rotated about an axis 8 and has a through opening 20.
  • This eyelet (cf. also FIGS. 1, 2 and 3) has two surfaces 24 with working parts 26 and 26 'which are approximately frustoconical, coaxially arranged and with their tapered ends opening into the common opening.
  • the working sections 26 and 26 ' are the opening 20 traversing linear portion 38 of the hook 30 can be brought into operative connection.
  • the hook 30 of the crank rod 32 has a total of 4 sections 34, 36, 38 and 40, of which the section 38 is approximately perpendicular to the axis of the crank rod and is circular in cross-section, while the section 40 serves for the hook 30 in the eyelet 10 hangs when the crank rod 38 is not operated.
  • the length a of the section 38 is greater than the maximum inner diameter d1 of the eyelet 10 with the opening 20.
  • the cross section of the crank rod is circular and has an outer diameter d2.
  • the opening 20 is a circular opening, but generally also oval could.
  • the figures also show that the opening 20 is circular and that the section 38 runs approximately parallel to the surfaces 26 and 26 'which are operatively connected to it (see FIG. 5).
  • the section 38 has a circular cross section and protrudes from the two sides of the eyelet 10, so that it is in operative connection with the eyelet 10 even when the axis 6 encloses an angle of up to 60 ° with the axis 8.
  • the base body 14 of the eyelet is essentially cylindrical, has frustoconical recesses with surfaces 24 and is provided with a pin 12 with a blind hole 16 and a transverse hole 18.
  • a driven part of a transmission (not shown) of an awning can be inserted into the blind hole 16 and connected in a rotationally fixed manner.
  • the section 36, which runs approximately parallel to the axis 6, and the section 34 are selected such that they do not come into contact with the eyelet and thus an unimpeded driving of the eyelet 10 is ensured.
  • the advantages achieved by the invention are, in particular, that no indifferent force transmissions occur when the crank rod is actuated, even if the longitudinal central axis of the crank rod 32 defines a relatively large angle with the axis of rotation 8 of the eyelet.
  • the wear on the eyelet, which results from the existing friction, is even and the operation of the crank rod is much easier.
