Definitions

  • the invention relates to a key module with a bell-shaped or dome-shaped key body made of elastic material, which has an edge delimiting its open side, and with a plastic housing part which at least partially accommodates the key body and into which the key body with its closed side can be used beforehand and with outward-facing approaches provided on the key body near its edge, which engage in recesses or pockets which are provided transversely to the axis of the key body in the plastic housing part.
  • Such a key block is already known from DE-GM 83 34 679.
  • the approaches which engage in recesses in the plastic housing part serve to hold the key body uncomplicatedly in the plastic housing part, so that an easy-to-use composite body consisting of the key body and plastic housing part is formed.
  • the object of the present invention is therefore to design a key module of the type mentioned at the outset in such a way that the key body can be inserted into the plastic housing part unhindered, that is to say without deforming it, and the key body, after insertion, together with the plastic housing part, can be handled easily Composite body forms.
  • this object is achieved in that on the open side of the key body, the approaches of the key body detecting boundary walls of the plastic housing part are formed only by swivel bodies which are integrally connected to the plastic housing part via film hinges.
  • the approaches of the key body are formed by a web which surrounds the key body in the vicinity of its edge and that the plastic housing part has an inner wall adapted to this web with a contact surface which, when the key body is inserted in the plastic housing part is effective as a stop.
  • the support surface forms a retaining edge for the key body, the inner wall automatically centering the key body in the plastic housing part, so that when the key body is inserted into the plastic housing part, no additional measures are required to align the key body and the plastic housing part with one another.
  • the pivoting bodies each movable in a plane parallel to the axis of the key body, have holding hooks which, in a locking position of the pivoting bodies, assume a parallel position to the contact surface of the inner wall and in this parallel position to the contact surface of the inner wall one of the Have the appropriate distance between the thickness of the key body bar.
  • the web of the key body is advantageously only gripped by the plastic housing part on opposite sides in the axial direction of the key body.
  • the function of the key body is in no way impaired by the mounting of the key body in the plastic housing part.
  • the swivel bodies have barbs which can be latched behind edges of the plastic housing part.
  • the key module has an essentially hollow cylindrical plastic housing part 1, which on the side facing a contact plate, not shown, merges into an approximately rectangular base 2. From this side, a bell-shaped or dome-shaped key body 3 made of elastic material is inserted into the plastic housing part 1, in such a way that the axes 4 of the plastic housing part 1 and key body 3 run coaxially with one another and the open side 5 of the Key body 3 facing the contact plate, not shown.
  • retaining pins 6 protruding from the base 2 of the plastic housing part 1 in the direction of the plate penetrate holes in the plate and thereby hold the button module on the plate.
  • the key body 3 is pressed with the aid of the plastic housing part 1 with an edge 7, which surrounds the open side 5 of the key body 3, against the plate, thereby forming a contact space which is closed off from the outside, in which contact surfaces are formed on the surface of the plate are located, which can be connected to each other by a movable contact 8, which is fixed concentrically to the axis 4 on the ceiling 9 of the key body 3.
  • a key button 11 which is guided and held by the plastic housing part 1
  • the key body 3 can be caused to break in, as a result of which the movable contact 8 lies against the surface of the plate (not shown). If the button 11 is released, the button body 3 automatically returns to its original shape and also resets the button 11.
  • keyboards it is desirable to be able to handle the key module consisting of key body 3 and plastic housing part 1 together as a composite body, although key body 3 and plastic housing part 1 are parts which are manufactured separately from one another.
  • the key body 3 is provided on its outside near its edge 7 with a circumferential web 12 which is integral with the key body 3 and projects from the key body 3 at right angles to the axis 4.
  • the plastic housing part 1 has in the area of its base 2 an inner wall 13 with a support surface 14 facing the plate, not shown.
  • pivot bodies 17 are provided on the base 2, in the middle of the side walls 15 of the base directed away from the axis 4, in one piece with the plastic housing part 1 via film hinges 16.
  • the swivel bodies 17 have projections 19 in the area of their holding hooks 18, which are barbed behind edges 20 of the base 2, which run parallel to the axis 4 when the swivel bodies 17 are in the locking position. From Fig. 2 it can also be seen that the holding hooks 18 on the open side 5 of the key body 3 form the only boundary walls for the webs 12 of the key body 3, so that the key body 3 on its open side 5 only by the holding hooks 18 of the Swivel body 17 is held in the plastic housing part 1.
  • FIGS. 3 to 5 how the pivoting bodies 17 are initially in a free state before the key body 3 is inserted into the plastic housing part 1, in which the holding hooks 18 hold the receiving space 21 of the plastic housing part 1 for the key body 3 release freely.
  • the key body 3 therefore falls automatically under the influence of gravity into the receiving space 21, it only being necessary to ensure that the closed side of the key body 3 is directed downward in this case.
  • the inner wall 13 of the base 2 automatically centers the key body 3 with respect to the plastic housing part 1 and forms with its support surface 14 a holding edge which acts as a stop for the key body 3 in the direction of insertion.
  • the swivel bodies 17 are brought into the locking position.
  • the holding hooks 18 of the swivel body 17 are located on the side of the web 12 facing away from the support surface 14.
  • the key body 3 is also on the plastic in the direction facing away from the support surface 14 - Housing part 1 fixed.
