    [001] The present invention relates to a key module for a key on a keyboard and a process for producing a key module for a key on a keyboard.
    [002] Of a total number of keyboards produced annually, a considerable part is required for the so-called "GamingSegment" (gaming segment). In order to be able to operate computer applications well, even in dark environments, some keyboards already have backlit key heads. When playing computer games, for example, however, in addition to the possibility of identifying keys regardless of brightness, a tactile perception when activating the keys is also important. In particular, the player, when activating the keys, should feel sufficient resistance with a sufficiently traveled path to be able to guarantee a clear separation of different feeding orders in complex and fast games.
    [003] US 7,172,303 B2 describes an illuminated keyboard with a transparent, lacquered key button, the symbol of which is illuminated by a light source. A symbol applied to the surface with a laser is then illuminated by a light-conducting channel. The light source is then located outside of a key button region.
    [004] To adjust different colors of a keyboard backlight, until now, in general, several LEDs (light-emitting diodes or light-emitting diodes; ing. "Light-Emitting Diodes") are generally used. For the illumination of the key symbols, for example, possibly, light channels or channels as light conductors are required. For example, it is not always guaranteed that the key symbols are evenly illuminated. Keyboards with a rubber "Domschalt" mat can also be used.
    [005] In view of this, the present invention provides an improved key module for a key on a keyboard and an improved process for producing a key module for a key on a keyboard.
    [006] According to embodiments of the present invention, an advantageous key module is available, especially for a backlit key on a keyboard. It can then be, in particular, a key module with a break in the module base for housing a light source, for example, an RGB lighting diode, and with a special module cover, configured for light distribution. Expressed in another way, the module base and / or the module cover of the key module has a segment for housing the light source and / or a segment for conducting radiated light through the light source.
    [007] Advantageously, according to the embodiments of the present invention, a uniform backlighting of a key symbol can be obtained. It is then possible to use an existing module model with slight modifications. Thus, thanks to small changes in details of the key module, or none at all, or only small changes, when a module is produced, a clear, uniform backlighting of the key symbol can be obtained, for example, even without the use of a key. additional components, especially a light conductor or additional light conducting channel. As a result, there can be a standardized module assembly, especially a standard MX module assembly, for example, a conductive plate assembly or frame assembly. Only one light source per key module is required. So, for example, there is no additional request for manufacturing facilities or manufacturing automatics.
    [008] A key module especially advantageous for a keyboard type, the key module having a module base, a module cover attachable with a module base, and a key tucho for coupling a key button translucent, at least in one symbol segment, is characterized by the fact that the module base has at least one opening between a bottom segment of the key module and the module cover, and that the module cover features a translucent segment for light from a light source, especially a variable color light source for backlighting the symbol segment of the key button that, in a state of the module cover attached to the module base, is aligned with, at least one opening of passage. Preferably, the translucent segment and the passage opening are aligned along a straight line, still preferably along a straight line parallel to an axis of longitudinal extension of the key tappet. By aligned, then, it is understood, in the sense of the present invention, such an arrangement in which the light from a light source, especially from the light source of variable color, can radiate from the direction of the passage opening or the passage opening to and through from the translucent segment to the backlight of the symbol segment of the key button.
    [009] A keyboard can have at least one key, in which a key module is provided per key. A key can have the key module or be formed by the key module. As for the key module, it can be, for example, a so-called MX module or similar. By using or mounting a key module on a keyboard, backlighting the keyboard key can be implemented. The module base and the module cover of the key module can represent, in a mutually coupled state, a key module base body. In an assembled state of the key module, the key tuple can be partially housed in a key module base body formed by the module base and the module cover of the movable key module, along a longitudinal extension axis of the key tucho. The key tappet can then extend through an opening in the module cover. Thus, the key tappet may have a segment protruding from the module cover, depending on its movement or activation. The bottom segment of the key module may have a partial segment of the module base. In the bottom segment, the key module can be applied to a support element. In a joined or assembled state of the key module, the module cover can be arranged between the module base and a key button or key button coupled to the key tappet.
    [0010] According to an embodiment, the key module may have the light source, preferably a light source of variable color. The light source can then be arranged close to the bottom segment of the key module or on the module cover. As for the light source, it can be a lighting diode (LED, "Light Emitting Diode"). As for the variable light source in color, it can preferably be an RGB or RGB-LED light diode or red-green-blue light diode. As for the light source, it can also be a surface-mounted light source or SMD light source ("surface-mounted device"). The light source can be designed to radiate light through the translucent segment of the module cover to a coupled key head, or a dockable button button mounting location. Alternatively, the light source can be performed to radiate light through the through opening of the module base and the translucent segment of the module cover to a coupled key button or a dockable key button mounting location. This form of execution provides the advantage that light or any color selection of the light radiated by the light source is made possible for backlighting the key button or key button by means of only one light source. There may also be a standardized surface fixation or SMD mounting of the light source, especially RGB-LED.
    [0011] Especially, an axis of longitudinal extension can be arranged at a distance from the installation location of the light source. Also, with respect to an observation direction along the longitudinal extension axis, a light source mounting region may be distanced from a keyhole mounting region. The longitudinal extension axis of the key tappet can then extend through a central point or region of the central point of the key module. This form of execution provides the advantage that the keyhole does not impair the illumination of the key button, as the light source can be arranged or is arranged at a distance from the keyhole.
    [0012] Also, the key module can present the translucent key button, at least in a symbol segment that is coupled to the key tappet. The key button may then have, on one side facing the module cover in the coupled state, a light diffuser device for diffusing light from the light source to at least one region of the key button comprising the segment symbol. The key button may represent a part of the key module visible to an operator and operable by compression. As for the installation of light diffusion, it can be a diffuser plate, diffuser area or similar. This form of execution provides the advantage that by means of this key button with a light diffusing device, thus, the light from the light source can be distributed evenly across the symbol segment.
    [0013] In addition, the key tapp can be made translucent to the light of the light source. This form of execution offers the advantage that uniform illumination or backlighting of the key button can be improved, as this key tappet does not represent a relevant obstacle to the light of the light source.
    [0014] The module base or alternatively, the module cover or, alternatively, the module base and module cover may have a segment executed translucent, at least partially, to the light from the light source. Advantageously, the module base and / or the module cover comprise a translucent region in a wall segment, leading to the key tappet. The translucent region can be made of translucent material from a passage or opening, leading to the key tappet. Preferably still, only the wall segments visible from outside the module base, or from the module cover up to the wall segment of the module cover leading to the key button, are made translucent, the interior wall segments being covered by these translucent configured wall segments. The module base or module cover can then be made of a combination of a non-translucent material and a translucent material. Alternatively, the module base or module cover can be configured to reduce production costs entirely from a translucent material, with the non-translucent regions of the module base or the module cover provided with a non-translucent cover. In addition, alternatively, the module base or module cover can be configured entirely of a non-translucent material, the translucent segment of the module base or module cover being formed by at least one passage or opening.
    [0015] Depending on the preferred form of execution, a more homogeneous illumination of the symbol segment of the key button can be obtained. In other words, a flatter or more uniform key button illumination is achieved. Furthermore, light scattering for a neighboring key module or key pad can be largely or approximately completely avoided.
    [0016] According to the present invention, the passage opening is provided to allow the passage of light from the light source and / or performed to absorb at least a partial segment of the light source. The through opening can then have an opening profile with an area that corresponds at least to a base area of the light source. With this, the light source can project, at least partially, into the passage opening, or the light from the light source can pass through the passage opening. This form of execution provides the advantage that the light source can then be arranged close to the bottom segment of the key module or on a support element for support of the key module, which allows an easy assembly of the key module. key.
    [0017] The translucent segment of the module cover may then have an irradiating aperture of irradiating light from the light source or a light diffusing device. The light diffusing device can be configured as a diffusing plate or diffusing area. The diffuser area can preferably be made in the form of a lens or in the form of a prism for backlighting the symbol segment of the key button. Alternatively, the diffusing area can advantageously configure other forms suitable for the backlighting of the symbol segment, such as, for example, a spherical segment area. The light diffuser device can then be arranged in an area of the module cover facing the module base or the key button in the assembled state of the key module. The module cover thus has, at least in the region of the light diffusing device, a translucent or transparent material for light from the light source. This form of execution provides the advantage that, thus, the light from the light source can be uniformly diffused for illumination or backlighting of the key button. In the case of the irradiation opening, the illumination of the module cover is lighter compared to the light diffusing device, in the region of the key button opposite the irradiation opening.
    [0018] According to another embodiment, a light-conducting device for guiding light from the light source may be provided. The light-conducting device can then be arranged extending at least from the passage opening of the module base to a light-conducting opening executed by the translucent segment of the module cover. The light-conducting device may then have a light-conducting channel or light-conducting channel. At one end of the light-conducting device facing the coupled key button, a light-diffusing device, especially a diffusing plate or a diffusing area, described above, may be arranged. The light diffusing device can then be provided in the vicinity of the key button. Preferably, a surface side of the light diffusing device facing the key button may be disposed between a surface side of the nearest module cover, facing the key button, and located on top of the key button. The arrangement of the light diffuser device is then preferably selected in such a way, and the key button can be activated unimpeded. Even more preferably, the light diffusing device can form an activation stop for the key button. In other words, a maximum activation path for the key button and / or key tappet corresponds to a direct distance from the bottom side of the key button to the surface side of the light diffusing device opposite that bottom side. Alternatively or even preferably, the surface side of the light diffusing device facing the key button and the surface side of the nearest module cover facing the key button are in a plane. In addition, alternatively, the surface side of the light diffuser device can be arranged between the surface side of the nearest module cover, facing the key button and the passage opening of the module base. The preferred embodiment provides the advantage that the light source can be arranged in the bottom segment of the key module, but a light conduction for the attached key button can be improved by the light-conducting device, the light-conducting device being able to light is reachable as close as possible to the key button for better lighting.
    [0019] According to another preferred embodiment, the light-conducting device can be a separate component, which can be applied to a key module and, even more preferably, releasably applied. For this purpose, preferably, at least the light-conducting device has fixing means for applying the light-conducting device to the key module. Such fastening means can, for example, be usual quick-connect means such as quick-connect hooks or quick-connect pins, which are provided to cooperate with the through opening of the module base. The quick-fit hook can, for example, be provided for quick-fit in the through opening of the module base, or in the trans-lucid segment of the module cover, or for the rear engagement of a through opening or the edge, limiting or by setting the translucent segment. The quick-fit pin can, for example, be made as a plug-in pin, which preferably also has a thickness of the cross-section required for a compression adaptation, corresponding to the thickness of the cross-section, at least, with an opening width of the passage opening or translucent segment. Even more preferably, the quick-fit pin can be formed by tapering towards the passage opening housing or the translucent segment, to facilitate assembly. Alternatively, the key module and the light-conducting device may have corresponding quick-connect means, with both the light-conducting device and the key module, quick-fit projections, such as quick-fit hooks and the other quick-fit notches, or quick-connect projections correspondingly associated with these components for housing the quick-fit means. Even more preferably, the module cover and / or the module base may have corresponding quick-fit means. Using a separately applicable light-conducting device, depending on demand, a keyboard that can be equipped with key modules can be equipped, with which production costs can be reduced.
    [0020] A particularly advantageous process for producing a key module for a key on a keyboard has the following steps:
    [0021] providing a variant of a previously mentioned key module, as well as a support element for supporting the key module;
    [0022] joining a light source, especially a light source of variable color conducting and mechanically with the support element; and
    [0023] application of the key module to the support element, so that the light source is aligned with at least one passage opening of the module base and the translucent segment of the module cover.
    [0024] The process can be advantageously carried out with a variant of the previously described key module. By executing the process, a variant of the previously described key module can be advantageously implemented.
    [0025] According to an execution method, in the availability stage, a first version of the key module can be made available. In addition, at the joining step, the light source can be arranged on the support element. For example, the support element may have a conductive plate. The light source, at the joining stage, can be arranged by means of surface fixation on the conductive plate. The first version of the key module comprises a key module for a key on a keyboard, the key module having a module base, a module cover attachable to the module base and a key tucho for coupling a translucent key, at least on a symbol segment, characterized by the fact that the module base has at least one opening opening between a bottom segment of the key module and the module cover, and the module cover has a translucent segment for light from a light source, especially a variable color light source, for backlighting the symbol segment of the key button, which, in a state of the module cover coupled to the module base, is aligned with at least one opening opening. In addition, the key module can optionally display the light source, especially the variable color light source; a longitudinal extension axis of the keyhole may be arranged at a distance from a light source mounting location, the key module may have the translucent key button, at least in a symbol segment, which is coupled to the keyhole , the key button being able to present, on one side facing the module cover, in the coupled state, a light diffusing device for diffusing light from the light source through the symbol segment; the key tucho can be made translucent to light from the light source; the module base may have a through opening, which is permeable to the light of the light source and / or made to accommodate at least a partial segment of the light source, and / or the translucent segment of the module cover may have an irradiating aperture of irradiating light from the light source or a light-scattering device.
    [0026] According to another form of execution, in the availability stage, a second version of the key module can be made available. In addition, at the joining step, the light source can be arranged on the support element. Thus, the process may have a step in the arrangement of the light-conducting device for conducting light from the light source, so that the light-diffusing device extends at least from the through opening of the module base to the opening of the light source. light conduction from the module cover. The third version of the key module comprises a key module for a key on a keyboard, the key module having a module base, a module cover attachable to the module base and a key tucho for coupling a translucent key on at least one symbol segment, characterized by the fact that the module base has at least one opening opening between a bottom segment of the key module and the module cover, and the module cover features a translucent segment for light from a variable color light source for backlighting the button segment symbol segment, which is aligned in a state of the module cover coupled with the module base with at least one through opening . Depending on the third version of the key module, the module base may have a through opening, and the translucent segment of the module cover may have a light-conducting opening, and, in addition, a conductive device may be provided. of light for conducting light from the light source, the light conducting device being able to extend at least from the passage opening of the module base to the light conducting opening of the module cover.
    [0027] The invention will be explained in detail as an example based on the attached drawings. Show:
    [0028] Figures 1A to 9C - key modules, according to examples of execution of the present invention; and
    [0029] Fig. 10 - a flow diagram of a process, according to an example of execution of the present invention.
    [0030] In the following description of preferred embodiments of the present invention, for the elements represented in the various figures and of similar action, the same or similar references are used, dispensing with a repeated description of these elements.
    [0031] Figure 1A shows a perspective view of a partially mounted key module 100, according to an example of the present invention, in a support element 110. The key module 100 is thus represented in figure 1A in a partially incomplete assembly status. As for the key module 100, it is a key module for a key on a keyboard. From the key module 100, a light source 120, a module base 130 with a through opening 135, and a key tuple 140 are shown in figure 1A. The light source 120 and the module base 130 are arranged. on the support element 110. The support element 110 has, for example, a conductive plate. The key tappet 140 is arranged on the module base 130.
    [0032] The light source 120 of the key module 100 has, for example, an RGB or RGB-LED light diode (RGB = red-green-blue; LED = light diode, English "Light-Emitting Diode" ). Light source 120 is executed as light source 120 of variable color. The light source 120 is connected with the support element 110, for example, by means of surface mounting, in an electrically and mechanically conductive manner.
    [0033] The module base 130 of the key module 100 has the through opening 135. The through opening 135 is performed to house the light source 120, or to allow the light source 120 to pass through the through opening 135. The module base 130 is arranged on the support element 110. One side of the module base 130 facing the support element 110 then represents a bottom segment of the key module 100. In other words, the module base 130 it is so arranged in the support element 110 that the light source 120 extends, at least partially, through the through opening 135. The through opening 135 is shaped in an edge region of a base area of the module base 130. The module base 130 also has a housing segment for the key tucho 140. The housing segment of the module base 130 is formed in a central region of the base area of the module base 130.
    [0034] The module base 130 shows, in the view from the top represented in figure 1A, an approximately rectangular contour. A base body of the keyhole 140 has, in the top view shown in Figure 1A, also an approximately rectangular contour. The base body of the key base 140 is arranged approximately in the center, on the module base 130. The key tuple 140 has a cross-shaped elevation, which rises over a surface of the basic body of the key tuple 140. The elevation can, for example, be formed by two intersecting threads. The elevation may be arranged centrally on the surface of the base body of the keyhole 140. Segments of the module base 130, located externally, form a continuous edge around the base body of the keyhole 140. The opening passage 135 is arranged close to the key tappet 140 on the continuous edge of the module base 130. The through opening 135 extends along a side wall of the key tap base body. The passage opening 135 has a rectangular opening cross section. The opening cross section can have a length that is at least twice the width of the opening cross section. The opening cross section can have a length that corresponds at least to a length of the side wall of the key tappet 140 facing the through opening 135. The through opening 135 can extend the entire length of the side wall of the key tucho 140. The through opening 135 and the key tucho 140 can be separated from each other by a narrow thread, which is formed by a segment of the continuous edge of the module base 130.
    [0035] The key tuple 140 of the key module 100 is partially arranged in the housing segment of the module base 130. The key tuple 140 is located away from the module base 130 and the support element 110. In other words, a the first end of the key tuple 140, for example, at least a part of said base body of the key tuple is housed in the key module 100 and a second end of the key tuple 140, which is formed by at least one part of the aforementioned elevation of the key tucho 140, is shaped as a coupling segment for coupling a key head or key button.
    [0036] Expressed in another way, in figure 1A, for example, a so-called MX module is shown as the key module 100 with an RGB lighting diode housing device in the form of the passage opening 135. In the figure 1A, the key module 100 with the opening 135 is represented as a housing for the light source 120 or RGB light diode. The passage opening 135 can be carried out as a break in the module base 130 or bottom segment, in which the light source is immersed. Thus, for example, a standard MX module fund with a small modification can be used. With such a disposition or positioning of the light source, a translucent configuration of the key tucho 140 can be dispensed with, because by light of the light source 120, a symbol executed on a coupled key button is directly illuminable. Optionally, it is possible to configure the key tucho 140 of translucent or transparent material, to increase a retro-illuminable area in a key button. Then, a further opening can be provided in the side wall of the module base 130 and / or of the module cover 150 facing the key tucho 140 to pass the light emitted by the light source 120. With this, it can be more uniform illumination of a key button is achieved.
    [0037] According to an example of execution not shown, the module base 130 can have one or more other openings for one or more other light sources. For example, another through opening may be arranged on one side of the key tappet 140 opposite the through opening 135.
    [0038] Figure 1B shows the key module 100 of figure 1A from a rotated perspective with respect to figure 1A, the key module 100 being shown in a more advanced assembly state compared to figure 1A. The representation in figure 1B corresponds to the representation in figure 1A, regardless of the modified perspective, except for the fact that the key module 100 additionally shows a module cover 150 and, conditioned by the representation, the light source, as well as the passage opening, are covered in view. Thus, in figure 1B, the key module 100, the support element 110, the module base 130, the key tuple 140 and the module cover 150 are shown.
    [0039] The module cover 150 is coupled with the module base 130. The key tuple 140 extends through an opening in the module cover 150. The second end or the coupling segment of the key tuple 140 protrudes, then, of the module cover 150. The module cover 150, according to the exemplary embodiment of the present invention, shown here, is formed of a translucent and / or transparent material.
    [0040] Expressed in another way, in figure 1B, a translucent module cover 150 or MS cover of the key module 100 is additionally shown. The module cover 150 is made of transparent material and functions as a light conductor between the source light and the dockable key button. The module cover 150 may have a light diffusing device not explicitly shown in figure 1B. By a specific configuration of the light diffusing device or light diffusing area, an illuminable area can be additionally increased on the key button.
    [0041] Figure 1C shows the key module 100 of figure 1B from a rotated perspective with respect to figure 1B, the key module 100 being shown in a different mounting state with respect to figure 1B. The representation in figure 1C corresponds to the representation in figure 1B, regardless of the modified perspective, except that from the key module 100, in addition, a key button 160 is shown with a symbol segment 165, the key module 100 is shown in a separate state from the support element 110 and, conditioned by the representation, the key tappet, the light source and the passage opening are concealed in view. Thus, in figure 1C, the key module 100, the support element 110, the module base 130, the module cover 150, the key button 160 and the symbol segment 165 are shown.
    [0042] The key button 160 is coupled with the key tappet, although this is not shown in figure 1C, due to the representation. More precisely said, the key button 160 is coupled to the coupling segment or to the second end of the key tappet. The key button 160 then traverses, for example, the module cover 150 and the module base 130. The key button 160 has the symbol segment 165. The symbol segment 165 comprises, according to the example of execution of the present invention described here, for example, "AAA" as a key symbol or symbol or sign. The key button 160 is then made translucent on the symbol segment 165. When the key button 160 is illuminated by means of the light source, the symbol segment 165 is then backlit. As for the key button 160, it is a part of the key module 100 visible and manipulable to a user. When being manipulated, the key module 100, by a user, the key button 160 is movable together with the key tappet relative to the module base 130, the module cover 150 and the light source, as well as in relation to , to the support element 110.
    [0043] Expressed in another way, in figure 1C, a complete key module 100 is shown. The key button 160 is executed, for example, as a transparent key button, which is coated or lacquered impermeable to light with a layer of lacquer. In the symbol segment 165, the lacquer layer is removed, for example, by means of a laser. A symbol contained in the symbol segment 150 is backlit by the light source in the form of an RGB light diode in different colors. A selection of an irradiated color by means of the light source for software or hardware illumination is adjustable by an individual user, with the desired frequency and at any time.
    [0044] Figure 1D shows the key module 100 of figure 1C from a modified perspective with respect to figure 1C, the key module 100 being shown in a different mounting state with respect to figure 1C. The representation in figure 1D corresponds to the representation in figure 1C, regardless of the modified perspective, except that the key module 100 is shown in a state applied to the support element 110 and, due to the representation, the key tuple, the module cover, light source and through opening are hidden in view. Thus, figure 1D shows the key module 100, the support element 110, the module base 130, the key button 160 and the symbol segment 165.
    [0045] With reference to figures 1A to 1D, attention is drawn to the fact that, when the key module 100 is produced, the 120 or RGB-SMD-LED light source is welded on the support element 110 or the conductive plate. A fitting of the key module 100 on the support element 110 can, thanks to standardized component elements, be done by a standard process on the support element 110. An RGB-LED as a light source 120 has, with four connections or connection pins or so-called "pins", two connections more than a standard LED.
    [0046] Figure 2 shows a top view of a key module 100 for a key on a keyboard, according to another example of execution of the present invention.
