Definitions

  • Keyboard with a cover over at least vain key in particular a text editing and / or photo typesetting device
  • the invention relates to a keyboard with a cover over at least one key, in particular a text editing and / or photo typesetting device, which may have a character or a symbol on its top.
  • This plastic film is provided with printed symbols or characters at the points that come to lie above the keys, which correspond to the assignments for which the overlay is intended.
  • This cover sheet made of a plastic film is, if at all, only attached in its entirety over part of the keyboard or the entire keyboard, ie the cover sheet covers several keys. To operate this. To make buttons as difficult as possible, the plastic film can have incisions between the points that come into contact with the buttons. -
  • This overlayer consisting of a plastic film can often be regarded as temporary, which is of high quality. Character, especially of text editing and / or eeto typesetting devices, is hardly appropriate.
  • this overlayer can slip in its entirety, so that the characters or symbols printed on it are incorrectly assigned to the individual keys Sm unfavorable case, despite a number of conceivable auxiliary measures, which also. are known, such as the mentioned cuts or a color marking of certain fields of the overlayer, must therefore be in the Use with a reduction in the otherwise comparable conditions, however, the tactile speed can be expected when the overlap is removed.
  • the present invention is therefore based on the object of providing a cover plate in connection with a keyboard, with which entire groups of keys are not necessarily covered, but rather can be individually assigned to the individual keys.
  • the overlayer should form a unit with each button, which ensures a fixed assignment of the overlay to the respective button. This means that the overlayer should not slip appreciably, even if it is handled improperly. On the other hand, the overlap should still be easy enough to release from the button if the assignment of this button is changed. After all, the overlay should give an aesthetically particularly satisfactory impression which should differ as little as possible from that of the original key.
  • the overlap els cap is formed with a ground frame which can be pushed onto the key body without having a fixed connection with the key body due to the fit.
  • the secure fit of the cap over the key body during normal operation is ensured by the means for forming a force-locking connection.
  • the cap can therefore only be used Remove this connection from the key body so that it can be replaced by another cap if necessary.
  • the caps bear on their top - like the keys - the characters and symbols that are used to indicate the respective assignment of the key.
  • the loose fit of the cap to the key body is chosen so that the cap body can at most turn slightly and move laterally, so that safe actuation of the key is not jeopardized, while inadvertently moving the cap into the area of a next key, so that an incorrect assignment is signaled, is excluded.
  • the cap can be produced with little effort using one of the known plastics processing methods.
  • the means for connecting the cap and the key body are designed and arranged particularly expediently. - This connection is particularly reliable, can only be released with a defined application of force and is wear-resistant.
  • the cover layer is expediently designed such that the cavity of the cap is open at the bottom. - As a result, the cap can be easily pushed onto the assigned key body from above and pulled off from above without being impeded by adjacent key bodies.
  • the cap expediently bears a character or a symbol on its upper side.
  • This character or symbol indicates the assignment of the associated Key as usual the character or symbol engraved in the key.
  • the overlayer has no character or symbol, but only has a neutral surface with which at least one character or symbol of the key body which is incorrect for the current assignment is covered.
  • the cap advantageously has side walls enclosing the cavity, which are so high that the cap is supported on an approximately horizontal shelf of the key body. The forces required to depress the key can thus be reliably transmitted from the cap to the key body.
  • the keyboard with overlap has the advantageous features that the first ferromagnetic body is fastened to the inside of the upper wall of the cavity in the cap and is dimensioned such that it does not rest on the top of the key body. This avoids that the cap can tip on the key body and also that the top of the key body, which shows a character or symbol, is scratched by the ferromagnetic body.
  • the first ferromagnetic body is expediently arranged within an enclosure formed from the inside of the cap. - This allows the position of the ferromagnetic body to be reliably achieved to achieve the desired connection effect with the associated key or the key body on which the cap is pushed.
  • the keyboard is equipped with at least one key, which has a hollow inside under an upper wall. has in particular for receiving an actuating plunger, so formed that the second ferromagnetic body is attached under the upper wall of the cap on the underside of this wall.
  • the cavity normally present under the upper wall is used to accommodate the ferromagnetic body, which sits only a little away from the first ferromagnetic body accommodated in the cap in order to achieve a comparatively large tensile force to the cap and nevertheless does not interfere with the outside Way is visible.
  • both ferromagnetic bodies are permanent magnets which are arranged approximately polarized in the direction of the vertical axis of the key body in the key body or the cap such that both permanent magnets attract each other.
  • both ferromagnetic bodies are permanent magnets which are arranged approximately polarized in the direction of the vertical axis of the key body in the key body or the cap such that both permanent magnets attract each other.
  • the magnetic field runs essentially directly between the magnets and only slightly spreads to the surrounding space, so that, for example, the function of Hall elements that are to be controlled by pressing the key is not disturbed.
  • the upper wall of the cap pushed onto the key body expediently runs approximately parallel to the upper side of the key body. - This means that the usual button actuation level is essentially retained, i.e. the keyboard can be operated practically without getting used to the operator.
  • the keyboard with overlap is particularly advantageous
  • the side walls of the cap are raised beyond the top wall and have an inwardly bent edge in the raised portion, such that a sign or symbol-bearing shield and a plexiglass window covering this shield over the top of the top wall of the cap can be pinched under the edge.
  • the signs with the characters or symbols that are assigned to the respective assignments of the button can be easily exchanged on the cap on the one hand, on the other hand, these signs are protected and nevertheless clearly recognizable from the outside during the normal function of the cap.

  • the inside of the button body has one below the top wall by webs 6, 7 limited cavity in which an actuating plunger 8 extends from below.

  • the permanent magnet 18 cooperates through the top wall 3 of the key body, which, like the rest of the key body and the rest of the cap, is made of non-ferromagnetic material, so that the magnets exert tensile forces on one another, whereby the cap 12 is pulled onto the key body.
  • the magnetic force between the permanent magnets 11 and 18 is only so great that the cap can still be easily removed from the key body if necessary to to be exchanged for another cap.
  • the permanent magnets should not be dimensioned unnecessarily so as not to allow stray fields to arise, by means of which, for example, the proper function of Hall elements which are controlled by the key can be disturbed.

Abstract

Au-dessus d'un clavier d'une machine de traitement de texte et/ou photocomposeuse presentant sur sa face superieure des caracteres ou symboles, on dispose un chapeau lorsque la fonction declenchee par le clavier doit etre modifiee. Lorsqu'il s'agit d'attribuer des chapeaux individuels a certaines touches auxquelles ils sont lies, chaque chapeau est constitue par un capuchon (12) en materiel rigide. Le capuchon est forme de facon a laisser un vide a l'interieur de ses parois (13, 14, 15) et peut etre fixe sur le corps (1) de la touche en recouvrant sa face superieure (4), mais en restant amovible. Le corps de la touche et le capuchon comportent des dispositifs permettant la transmission de l'effort entre le capuchon et la touche.
