Definitions
- the present invention includes a holder for keys of a keyboard of electrical devices, which are guided and held against spring force.
- keyboards are e.g. B. in telephones as a separate component, the individual keys are held on their outer contours in separate guides of the keyboard.
- Brackets for keys in telephone sets are also known, in which the individual keys are guided and held in recesses in the upper part of the telephone on their outer contours.
- both embodiments have the disadvantage that there is a relatively large space between the individual keys.
- the present invention is therefore based on the object of demonstrating a holder for keys on a keyboard, which enables a compact arrangement of the keys with very little space.
- this object is achieved in that in the interior of the individual keys arranged and integrally connected with them are provided approaches that are arranged in the keyboard arranged and corresponding openings of the device housing, with at least two stroke limiters on the keys and securing the keys forming retaining elements are arranged, which engage in the area of the openings provided recordings.
- a further anti-twist protection of the keys can be achieved by choosing a rectangular cross-section for the approaches on the keys and the openings serving as guides within the device.
- the holding elements themselves can be designed in the form of a latching hook and have hook-shaped approaches at their free ends. As a result, the assembly of the individual keys is made easier by snapping into the recesses and, on the other hand, additional key guidance is achieved. For reasons of injection molding and assembly technology, it has proven advantageous to arrange these holding elements offset in the area of the outer contours of the keys.
- the keys 1 shown in the figures of a keyboard for a telephone station act via lifting bellows 2 of a rubber mat 3 made of elastic material on contacts of a circuit board 1 (not shown here).
- the individual keys 1 each have a cylindrical inside in the direction of the lifting bellows 2 Approach 4, which is guided in a round cross section of the telephone housing 12 which corresponds to it in shape and is arranged inside the telephone station 5.
- the slightly recessed interior of the cylindrical extension 4 causes the bellows 2 to deform, which in turn causes the button to return to the starting position when the button is not actuated.
- the keys 1 furthermore have four holding elements 7 arranged offset on their outer contours, integrally connected to them and forming a stroke limitation for the key, the free ends of which have a hook-shaped extension 8. These holding elements engage in the receptacles 9 arranged in the area of the openings 5 and thus, in addition to the stroke limitation of the keys, additionally guide and secure the keys against undesired falling out.
- the game ie. H. the clear width between the respective opening 5 and the cylindrical extension 4 of the key can be kept somewhat larger.
- the keys support each other to prevent rotation. For this reason, the gap 10 between the actuating surfaces 11 of the individual keys also narrows in the actuating direction.
