Definitions

  • the invention relates to a push button for touch shadows according to the preamble of claim 1.
  • a push button switch is known, the push button behind which is formed by means of two molded, resilient locking hooks; on a mounting plate oppositely directed hook can be locked. In the locked state, the rest position of the key is also defined, into which it is brought by the return spring.
  • the invention has for its object to provide a push button according to the preamble of claim 1 for commercially available pushbutton switches, which makes it possible to vary the restoring force of the pushbutton counteracting the pushing force without having to remove the pushbutton or pushbutton.
  • the object is achieved by the features specified in the characterizing part of claim 1.
  • Advantageous further developments can be found in the subclaims.
  • the construction according to the invention makes it possible, if necessary, to replace an additional compression spring by releasing an insert in the push button, the force of which is added to that of the energy accumulator already present in the pushbutton switch, for a compression spring with other characteristic values.
  • the release and reinsertion of the insert can be done in a simple manner, e.g. B.
  • the invention is particularly advantageous when it comes to adapting the restoring force of pushbutton switches to the needs of more or less severely disabled people.
  • the need exists in particular in clinics in which the restoring forces in call and dial button arrangements are to be changed frequently over a relatively short period of time.
  • the push button 1 shown in FIGS. 1 and 2 has a substantially cuboid shape.
  • two or three locking lugs 16 are molded onto the push button, which is expediently made of plastic.
  • these locking lugs 16 snap behind the opposite locking lugs 15 on resilient locking hooks 14, which are placed upright on the mounting plate 18 in which the pushbutton switch 13 is also fastened.
  • the entire arrangement is expediently covered by a cover plate 19 with a corresponding opening 20 through which the push button 1 protrudes.
  • the push button 1 is open and essentially hollow on the inside, but has a round opening 24 in the upper wall 23, which is followed by a tubular extension 21.
  • a cylindrical insert 2 can be inserted into this opening 24 or extension 21 from above, which can be connected to the push button 1 by means of a restriction.
  • corresponding extensions 22 are provided on the opening 24 of the push button, which allow insertion.
  • the Einrenknasen 4 can be undercut (Fig. 1) to improve centering and friction.
  • 2 latching cams 5 can be attached to the circumference of the insert, which snap in when the insert 2 is rotated in the direction of the arrow (FIG. 2) behind resilient tabs 6 of the push-button that are cut free. This reliably prevents automatic loosening.
  • a segment-shaped slot 7 is provided on the top of the insert 2 for attaching a coin as a tool.
  • the insert 2 is a hollow cylinder closed at the top, in which a tubular extension 8 formed on the end wall is contained.
  • This approach has two functions: on the inside it receives the plunger 9 of the pushbutton switch 13, while a helical compression spring 3 can be pushed over its outer surface.
  • This spring 3 which is dimensioned according to the required values, supports that of the energy accumulator 17, which is already installed in the commercially available pushbutton switch 13.
  • the push button 1 On its top, the push button 1, the cover 10 is placed, which gives it an appropriate conclusion. If it is made of opaque material, it is not immediately obvious to unauthorized persons which options are inherent in the push button. If it is made of transparent molding material, a label 12 can be inserted on which symbols or characters are attached.
  • the push button is slightly recessed on the top, the correspondingly graduated cover 10 fits into the peripheral edge 25 so that it is flush on the outside. In order to be able to easily release the cover 10, which for example snaps into place with a flat bead, there is a small one at one point on the upper edge of the push button 1 Recess 11 provided in the z. B. a fingernail can be attached.
  • Fig. 3 shows another version of the push button, in which two additional helical compression springs are used.
  • the outer structure is similar to the push button 1 previously described with reference to FIGS. 1 and 2, which is why the same reference numerals are used in part.
  • the locking lugs 36 are here, however, a component of resilient locking hooks 37 which protrude on the lower edge of the push button 31 in the extension of its side walls to such an extent that they snap behind the mounting plate 38.
  • the latter is provided with corresponding openings 39 for the passage of the locking hook 37.
  • the molded snap hooks 14 (FIG. 1) have been eliminated. Inside the push button 31 lacks the central insert.
  • tubular projections 35 are formed on the end wall of the push button 31 symmetrically to the center with a through-bore, which serve to receive a helical compression spring 33 each.
  • the bores for the springs 33 are somewhat expanded and closed by suitable inserts 32, which are engaged or engaged. To operate them, they are provided with a slot 34.
  • the push buttons 1 and 31 can also have a round floor plan.
  • the locking hooks 14 and 37 are then either diagonally or, if ⁇ s are more than two, distributed according to the circumstances around the circumference.
  • the compression springs 3 and 33 are used on site or exchanged according to requirements. For example, they are made available to the therapist of a clinic, who uses them in the care of disabled people with impaired movement coordination in devices that can be operated by them, such as telephone sets, control devices for windows, shutters, etc. These handicapped people cannot operate normal control buttons (operating force approx. 50 to 100 cN) without error, since positioning the finger on the push button is already a problem and triggering wiping contact operations. By using appropriate additional springs 3 and 33, the operating force can be increased to such an extent (up to a maximum of about 20 N) that incorrect operations can largely be ruled out.
