Definitions

  • the present invention relates to a manual actuating element for releasable arrangement on a shaft according to the preamble of claim 1.
  • the manual control element is to be understood quite generally as a manually operable element for operating or actuating a shaft. It can be, for example, a handle with which the switching shaft of a power switch or the like is actuated.
  • a manual control element has already become known which can be plugged onto and removed from the control shaft, for example of a mains switch, with an elastically deformable clamping device.
  • the known manual control element has a sleeve-shaped element, on the inside of which a small metallic body is provided, which is prestressed by a compression spring and which is pressed aside when the manual control element is plugged onto the shaft, as a result of which the manual control element is ultimately attached to the shaft.
  • the manual control element is a mass-produced component, plastic is often used to manufacture it, so that the spring device described above must be used after the manufacture of the plastic part in a second operation. In addition to the fact that this procedure is costly, there is also the risk that the spring device subsequently used is lost, for example when the manual control element is removed from the shaft, and the manual control element must therefore be completely replaced.
  • US-A-3 880 536 shows a manual actuating element for releasable arrangement on a shaft by means of an elastically deformable clamping device provided on a sleeve-shaped extension, the clamping device being formed in one piece with the sleeve, the clamping device being provided on the inside of the sleeve and there in the axial longitudinal direction has extending web-shaped clamping element.
  • a clamping element is designed such that an elastic effect is achieved via a cavity.
  • the present invention has for its object to provide a manual actuating element which is provided with a clamping device which enables an elastic clamping effect without a cavity.
  • a manual actuating element which can be removably attached to the shaft by means of an elastically deformable clamping device provided on a sleeve-shaped extension, the clamping device being formed in one piece with the sleeve.
  • the manual control element according to the invention has a clamping device which can be produced together with the manual control element during manufacture and therefore no longer needs to be followed by a second work step after manufacture, with which then the spring device is used.
  • the clamping device is arranged on the inside of the sleeve.
  • the clamping device according to one embodiment according to the present invention can also be arranged on the outer circumference of the sleeve-shaped extension, so that a clamping effect is brought about by a radially inward elastic deformation of the clamping device.
  • the clamping device has at least one web-shaped clamping element running on the inside of the sleeve in the axial longitudinal direction. This means that the clamping element extends over substantially the entire axial length of the sleeve-shaped extension in the longitudinal direction of the extension and is elastically deformed when the manual control element is placed on the shaft, so that the manual control element is held securely. To remove the manual control element from the shaft, it is only necessary to pull the element off the shaft, as a result of which the elastically deformed clamping device returns to its original undeformed position and shape.
  • the clamping element is T-shaped and formed with its base on the inside of the sleeve largely at right angles thereto.
  • This is to be understood to mean that the narrow side of the T-shaped clamping element is integrally formed on the sleeve, so that the wider side, which has the contact surface for arrangement on the shaft, extends in the direction of the shaft.
  • the clamping element has a contact surface which is rounded in cross section at its broad end facing the shaft, that is to say it is designed to be complementary to the shaft.
  • the clamping element extends largely over the entire axial length of the sleeve-shaped extension and can be formed in one piece or also divided, that is to say also formed from a plurality of segments running in the longitudinal direction of the sleeve, which are arranged one behind the other.
  • a centering of the shaft on the manual control element and an increase in the clamping force between the manual control element and the shaft can be achieved in that the clamping device has at least one web-shaped support element running on the inside of the sleeve in the axial longitudinal direction, the central axis of which is below a Inclined at an angle to the inside of the sleeve.
  • This very special design ensures that the support element is resiliently deformed when the manual control element is placed on the shaft, thus increasing the clamping force on the one hand and centering the shaft on the manual control element on the other hand.
  • the support element is formed at an acute angle at its end facing the shaft. This configuration causes an increase in the deformation and thus an increase in the clamping force at the acute-angled end.
  • the material for producing the manual control element is preferably a filled plastic, in particular filled polyamide.
  • the manual control element can have a shaped element which serves as a stop for at least one direction of rotation when the manual control element rotates. During the rotary movement of the manual control element, it is guided through a surface running parallel to the radial plane of the sleeve, with which the manual control element is rotatably supported on another surface.
  • the manual actuation element 1 in the embodiment shown has a circular configuration in the view from below, with the closer to the center of the manual actuation element 1 2 visible sleeve-shaped extension 2 is located.
  • the manual control element 1 is provided on its upper side with a handle 3, which has a spherical segment shape that cannot be seen from the drawing.
  • the outer circumference 4 of the manual control element 1 forms a first contact surface with which the manual control element 1 can be arranged on a support (not shown), for example a front panel of a control cabinet, in which there is a power switch, on the control shaft of which the manual control element 1 is plugged.
  • a support for example a front panel of a control cabinet, in which there is a power switch, on the control shaft of which the manual control element 1 is plugged.
  • the second contact surface 5 performs a function similar to the first contact surface 4.
  • the already mentioned sleeve-shaped extension 2 in the middle of the manual actuating element 1 has a clamping device, generally designated 6, in the area of its inside.
  • the clamping device 6 has a total of five individual clamping elements or supporting elements. All of these elements are formed in one piece with the sleeve-shaped extension 2 and therefore cannot fall out of the extension 2.
  • the clamping device 6 has a T-shaped clamping element 7, the contact surface 8 of which is directed towards the shaft and is straight.
  • this clamping element 7 there are two further T-shaped clamping elements 9, the contact surfaces of which face the shaft are each rounded.
  • a support element 10 is arranged in each case with acute-angled ends facing the shaft.
  • the individual clamping elements or support elements are elastically deformed, so that the manual control element 1 is securely held on the shaft.
  • the individual clamping elements 7, 9 and support elements 10 return to their original undeformed position and shape.
  • Fig. 2 of the drawing makes it clear that the clamping elements 9 extend over the entire length of the sleeve-shaped extension 2, so in the embodiment shown along the rectilinear extension designated by the reference numeral 2, which at its end facing the handle 3 integrally in the Handle 3 passes over, so that a high clamping force can be achieved with the clamping element 9 extending into the closed end region 1 of the handle 3.
  • the further clamping elements 7, 9 and support elements 10 shown in FIG. 1 can similarly also extend into the closed end region of the handle 3, which contributes to the secure holding of the manual control element 1 on the shaft.
  • Fig. 1 of the drawing finally shows a shaped element 12 which can be used as a rotation limit stop.
  • one or more locking elements can also be provided to form predetermined rotational angle positions of the manual control element on the contact surface of the control cabinet or the like, for example.
