Definitions

  • the present invention relates to a push button assembly which has been specifically designed for controlling glass raising and lowering devices in motor vehicles.
  • motor vehicles provided with electric glass raising and lowering devices usually comprise a push button assembly, including several push buttons,which are operatively coupled to controlling switches,for switching on and off the mentioned devices.
  • powder particles,moisture and the like may frequently enter inside the push buttons so as to impair a proper electrical contact of the microswitches.
  • the document DE-A-2 914 954 which is considered to represent the most relevant state of the art, discloses an electric pushbutton assembly structure including a membrane which protects exclusively a single switch: the membrane shown by this document is not continuous, but it is provided, at the central portion thereof, with a hole which is used for firmly clamping the membrane to the body of the operating pushbutton.
  • Such a configuration will require to make the pushbutton body into two pieces which must be successively connected to one another in a very precise manner, so as to provide a sealing relationship with the menbrane.
  • the membrane of this prior document is not affixed to a printed board.
  • the task of the present invention is to overcome the above mentioned drawbacks, by providing a push button assembly structure in which all of the electrical component parts are tightly separated from the outside environment, thereby providing a very high reliability in operation, with a comparatively simple construction.
  • a mai object of the present invention is to provide such a push button assembly on the push buttons of which is possible to represent letters, patterns and the like while preventing powder and moisture particles from absolutely penetrating inside said assembly.
  • Another object of the present invention is to provide such a push button assembly structure which comprises a very reduced number of easily and quickly assemblable component parts.
  • Yet another object of the present invention is to provide such a push button assembly structure which may be easily made starting from easily commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a push button assembly structure specifically designed for controlling motor vehicle glass raising and lowering devices, having the features of the characterizing portion of the main claim.
  • the push button assembly according to the present invention which has been overally indicated at the reference number 1, essentially comprises a box-like casing 2, which preferably though not necessarily has a parallelepipedal shape, which may be coupled, at the top thereof, to an electric wiring board which has been indicated overally at the reference number 3 in figure 1.
  • said electrical wiring board or base comprises a supporting foldable small plate 4 therewith a flexible printed circuit 5 is associated which is housed inside said foldable small plate 4 as said plate is bent to its final shape.
  • coupling members 6 are provided adapted for receiving the pins of the microswitches 7 for controlling the motor vehicle glass raising and lowering devices, which switches will be directly coupled at the insertion time.
  • the microswitches 7 may be of the single stage type, that is which directly control the glass lowering and raising devices as they are operated, or of the double stage type that is which provide a first operation in which the electrical contact is held for the overall time the push buttons are pressed and a second operation which is obtained by exerting a greater pressure on the push buttons.
  • the push button assembly comprises a resilient membrane, indicated overally at the reference number 10, which may be superimposed on the electric wiring board or base 3 and is provided with shaped portions 11, at the zone thereat said microswitches are arranged.
  • the mentioned shaped portions 11 are provided with a base portion 12, encompassing the respective microswitch, thereon there is superimposed as essentially frustum of cone shaped portion 13 provided for resiliency purposes, as it will be disclosed in a more detailed way hereinafter, and thereon a stiffening cylindrical portion 14 is arranged.
  • the membrane 10 is firstly provided as a tightness element which practically separates from the outside environment the region thereat there are formed the electrical wirings.
  • the shaped portions 11 are specifically designed to operate as a resilient return element for the microswitch operating push buttons, which are overally indicated at the reference number 20.
  • the push buttons 20 comprise a substantially rigid intermediate body, indicated at 21, which is coupled by contact to the mentioned cylindrical portion 14, on said body there being arranged a cap 22 having at least a translucid or semitrasparent portion 23 provided for receiving patterns and the like.
  • the cap 22 is peripherically provided, at the edge portions thereof, with flanged rims 24 adapted for operating as stop elements for the displacement of the push buttons 20, which are guided by throughgoing holes 25 formed through the top face of the box-like casing 2.
  • the membrane 10 is advantageously made of a transparent or translucid material, so as to allow for the light of a display lamp 30 to pass through, said lamp being housed in a seat 31 defined by said membrane, preferably at the central region thereof.
  • the membrane 10 also acts as a resilient return element for the single push-buttons.
  • the shaped portions 11 are provided, at the tops thereof, with a frustum of cone shaped portions 13, which may be resiliently deformed as the push button 20 is pressed but which is able of recovering to its original shape thereby practically acting as a resilient return element.
  • Figure 5 illustrates a push button assembly which is conceptually analogous to the above disclosed push button assembly and which is provided, at the electrical wiring board or base, with a spacer element indicated at 30.
  • a push button assembly has been made in which the push buttons, which are accessible from the outside, are practically tightly separated from the outside environment and from the electrical wiring components, thereby preventing powder and moisture from absolutely entering the push button assembly casing.
  • the specific shape of the membrane provides the latter with a multioperation characteristic since, in addition to the tightness function proper, said membrane, which is made from a resilient material, also operates as a return element for the single push-buttons.
  • Another important feature of the invention is the shape of the push buttons, or the patterns formed thereon can be easily modified, since said push buttons are practically formed by a cap which may be easily and quickly changed, thereby changing said patterns.
  • buttons may also be made from a soft material.
