Description

The The present invention relates to a housing having at least two housing longitudinal walls and two Housing transverse walls, for an inscribable push-button device, which, like a bell button, a receptacle for a label carrier, such as a nameplate, and a sensing device, wherein the housing at least has two housing chambers delimited from one another by a partition, of which a first housing chamber the label carrier and the other, second, housing chamber associated with the sensing device. Furthermore, the present invention relates Invention a Drucktastvorrichtung with such a housing.

Labelable pushbutton devices are widely used as a bell pushbutton. So is out of the DE 93 12 652 U1 a combined bell and shield button known. Keys of similar design are usually pivotally fixed to a bell housing and must be pressed or swiveled in order to actuate the bell, as a rule, the ping have a name tag, so that an easy finding of the desired bell is possible. The name tags are stuck on the outside of the button in simple models and arranged behind a viewing window for more sophisticated buttons. It has been shown that in such known buttons the replacement of the nameplate is not feasible without problems. Either the nameplate must be removed from the outside of the sign key or the viewing window must be removed from the shield key and the name badge must be inserted or exchanged for another one. In this lifting the viewing window from the frame of the shield button, it sometimes comes to breaking the viewing window, which must then be replaced by a new one. In addition, it has been shown that the nameplate often has to be inserted cumbersome at excavated viewing window behind this, where it is then between the viewing window and a retaining plate. To make the interchangeability of the nameplate easier, is in the DE 93 12 652 U1 provided that the holding plate in the frame can be fastened, in particular latched. This well-known combined bell and shield button is designed for a single bell.

The DE 31 03 449 A1 describes a known surface-mounted actuating mechanism for a bell. This comprises a cover cap with a circumferential side wall and a lower part, which together could also be referred to as a housing. The lower part has for mounting on a wall screw holes for mounting screws and fixed contacts of a push-button switch and optionally a festoon lamp for lighting a name badge. Further components are a cover cap which can be pushed onto the lower part and has a cutout and a pushbutton arranged in this cutout for actuating the switch against the force of a spring in the direction of the lower part, which push button is simultaneously designed as a support for the name tag. The push button is mounted so pivotable that it is on the one hand for actuating the switch in the direction of the lower part and on the other hand without disassembly of the top cap for inserting or replacing the nameplate by the recess of the top cap from the base away pivot. In this case, a force acting on the push button locking device is arranged on the lower part and / or on the top cap, which either releases the pivoting of the push button to the outside or limits the pivotability of the push button to the extent required for actuating the switch. The screw holes lie in a non-accessible even when swinging out the push button section of the base. This technical embodiment serves the purpose that on the one hand entitled the easy replacement of the nameplate and possibly provided for its lighting festoon lamp is on the other hand at the same time sufficient to protect the attachment mechanism from vandalism, theft or the like. The well-known surface-mounted actuating mechanism is designed in the described case for two bells, each bell are assigned in arranged on the lower part separate fixed contact and a separate contact spring.

A similar objective as the DE 31 03 449 A1 also pursues the DE 36 02 283 A1 , which describes under the name "name tag" a known inscribable push-button device having a housing of the type mentioned. In particular, this device refers to a nameplate with a usable in a rectangular breakthrough of a plate, provided in the region of its front with a peripheral edge housing frame in which the window frame formed by the housing receives a transparent plate holder in which a label held interchangeable and is covered towards the front of the housing frame out, the shield holder is mounted in pivot bearings and so by an edge of the window adjacent and parallel axis of rotation from the window to pivot from. The document states that large numbers of badges are needed for bell, letterbox and intercom systems, with the desire to be able to replace the shield without disassembling the entire device. For this purpose, it is further stated that in prior art devices, when a screw is provided, disadvantageously, the housing frame must be released from the plate to gain access to the clamped between the housing frame and the plate plate holder. If - as also previously known - a Verrastung or bonding of the housing frame with the plate selected, then it would be disadvantageous to solve this connection no further readily. The sign holder is therefore interchangeable only from the back of the plate ago, which makes even more disassembly than in the screw - namely the removal of the entire plate of the device - necessary. In view of this regardless of the type of mounting of the housing frame on the plate a simple, but only authorized executable exchange of the label from the front of the plate to allow without parts of the nameplate would have to be solved and removed from the plate, sees the DE 36 02 283 A1 a relatively complex complex of combined constructive features. This combination relates in particular to the storage of the shield holder in the pivot bearings and consists in detail in that the axis of rotation is parallel to a first narrow or transverse side of the window for receiving the shield holder, that the pivot bearing journals and slots in the facing longitudinal side walls of the Rack frame and the shield holder are formed, wherein the journals are perpendicular to the longitudinal sides of the shield holder and the slots are aligned with their large dimensions parallel to the front of the housing frame, so that the shield holder in the region of the pivot bearing parallel to the front of the housing frame limited adjustable and by means of springs is held in the second narrow or transverse side facing end position of the slots that locked in the pivoted into the window position of the shield holder with the associated second narrow side behind a locking shoulder of the housing frame and with the back supported on housing-fixed stops and that finally by means of an insertable into a receptacle of the housing frame key-like tool the shield holder in the latched second narrow side against the tension of the springs while canceling the detent position is parallel to the front of the housing frame slidably. The slot-like opening of the shield holder (receptacle) for insertion of the label (label carrier) is located in this known pressure sensing device on a side facing away from a sensing device. It is stated that the name tag described can be expanded by connecting to a narrow side of the window for receiving the shield holder in the housing frame a key holder, which can be provided depending on the application, that in the key holder either a key unit with open contacts or a Button unit can be used with moisture-tight encapsulated contact unit, preferably latched, is. Also this famous name tag is - like the combined bell and shield key according to the De 93 12 652 U1 - designed for a single bell.

Of the The present invention is based on the object, a housing of the initially mentioned type for an inscribable push-button device, in particular for a Bell button, to create that where nameplates in large numbers needed at a bell, letterbox and / or intercom, a simple assembly and disassembly allowed. Here are preferred additionally even with a simple change possibility the inscription, in particular a replaceability of a name tag, one possible simple structural design of the housing of the inscribable Drucktastvorrichtung and above In addition, opportunities should also be preferred given a secure protection against the intervention of unauthorized persons be.

According to the invention this is achieved in that the longitudinal side walls at least in the region of the sensing device associated with the second housing chamber breakthroughs for receiving a printed circuit board on which several similar switching contacts are located, each with a switching contact is switchable when operating the sensing device.

The Invention thus advantageously allows a plurality of housings in assembly technology easier Way on a circuit board with their long sides next to each other sort of sorting out.

So can in a Drucktastvorrichtung invention two or more shots for each a label carrier, two or more sensing devices and two or more housing provided are, with extending through the openings of the housing, the circuit board and associated with each sensing device in each case one switching contact of the printed circuit board is.

The provided according to the invention breakthroughs can If necessary, also in the area of the label carrier associated first housing chamber extend, which is particularly advantageous when on the PCB further contacts are located, which is the electrical connection one in the first housing chamber serve housed light source. If the breakthroughs too in the area of the first housing chamber extend, is a transverse wall opening between the two housing chambers to be provided in the partition wall between the chambers.

Furthermore, the invention also makes it possible to form the housing, the sensing device and the receptacle for the inscription carrier in such an advantageous manner that an exchange of the inscription carrier becomes possible without having to do so a disassembly of the pressure sensing device according to the invention is necessary. By simply pressing the sensing device from a rest position into a release position, an access to an opening for the introduction of the label carrier can be released, as will be described below. As a result, a protection against unauthorized manipulation is given with advantage, since the insertion opening for the chamber of the label carrier is not visible, because hidden by the located in the rest position sensing device.

in the With regard to the described prior art, there is a Another advantage of the housing according to the invention and the Drucktastvorrichtung invention in that the label holder for one Initial or new lettering not moved, for example, pivoted, needs to be, so that in the housing according to the invention no special, such Enable movements Drehlagerungsteile etc. must be provided and the constructive Structure can make accordingly easy.

Finally, can with advantage an increased protection against unauthorized manipulation be achieved in that the slot-like opening of the Recording for the label carrier is arranged next to the sensing device that the sensing device also in its active position the opening covering and that the taking of the release position of the sensing device can be blocked by means of a locking mechanism.

In The drawing figures are the same and corresponding parts always provided with the same reference numerals, so that they are in the Usually only be described once, but not for reasons of clarity for all Parts described in all figures, the respective reference numerals are indicated.

As first 1 and 2 show, a writable Drucktastvorrichtung invention, in particular a bell push button, a - to be explained in more detail in their individual parts - recording A for a label carrier 1 , in the case shown by a label 1a such as a nameplate made of paper, for example (see in particular 4 ), and a label holder 1b is formed. The receptacle A has a slot-like opening 2 for the introduction of the label carrier 1 on.

Furthermore, the inscribable push-button device according to the invention comprises a multi-part - also in its individual parts to be explained in more detail - - sensing device T, which by pressing from a rest position, the in 1 and 7 is shown in an active position in 2 is shown, is movable.

The sensing device T and the receptacle A for the label carrier 1 are arranged adjacent.

The slit-like opening 2 the receptacle A is arranged in such a way next to the sensing device T, that the sensing device T in its rest position - 1 - the opening 2 covers. This provides primary protection against unauthorized manipulation.

Also in its active position - 2 - The sensing device T covers the slot-like opening 2 from and gives only in a release position - 3 - an access to the opening 2 for the introduction of the label carrier 1 free. As a result, as mentioned above, increased secondary protection against unauthorized manipulation is achieved. In this case, the taking of the release position of the sensing device T preferably in both the rest, and active position by means of a sensing device T associated locking mechanism S can be blocked, which will be described in more detail below.

The exploded views in 4 and 5 show in a particularly vivid manner the individual parts of the device according to the invention. It is first clear that for the recording A and the sensing device T a common housing according to the invention 3 is provided. The housing according to the invention 3 initially has two in a known manner through a partition 4 separated housing chambers 3a . 3b on, of which a first housing chamber 3a the label carrier 1 and the other, second, housing chamber 3b the sensing device T is assigned.

The housing chambers 3a . 3b are formed in their basic shape cuboid or cuboid. Both chambers 3a . 3b are longitudinally through two common housing longitudinal walls 5 limited and are underside preferably by a common housing bottom 6 closed and thus have a compact and easy to mount shape. On the top are both chambers 3a . 3b open. In the transverse direction, the chambers 3a . 3b through the common partition 4 and in each case opposite to the partition wall 4 through a housing transverse wall 7a . 7b completed.

The upper edges of the longitudinal walls 5 as well as the partition 4 and the housing transverse wall 7a the first housing chamber 3a that the label holder 1 is assigned, make editions for the label carrier 1 , or it is in the range of these top edges of the housing 3 formed by additional webs, edges, heels or the like. Such requirements.

During initial assembly, the label carrier becomes 1 , but preferably only its label holder 1b , placed on these pads, thus covering the first housing chamber 3a from.

The housing chamber 3a itself can remain free or preferably also a - not shown - suitable light source, eg. As a light emitting diode, record, it being attached in the latter case that the label carrier 1 at least transparent, so translucent, is. Preferably, however, in particular for this case, at least the label holder 1b be transparent in the sense of a good illumination.

On the label carrier 1 becomes a transparent cover 8th , like the housing according to the invention 3 and the label holder 1b preferably made of plastic, laid and fixed there in a suitable manner. As materials for the cover 8th Glass or a plastic, such as polymethacrylic acid methyl ester (PMMA) or polyoxymethylene (POM), are particularly recommended.

It is thus clear that the receptacle A for the label carrier 1 underside through the top of the housing 3 especially through the edges of the walls 4 . 5 . 7a the first housing chamber 3a , and the top through the cover 8th is formed. On the side of the sensing device T, the receptacle A frontally open, there by the slot-like opening 2 for the introduction of the label carrier 1 is trained. On the opposite end face, the recess A through an upper wall piece 7c the housing transverse wall 7a the first chamber 3a locked.

In the 6 separately shown sensing device T, in the assembled state of its associated second housing chamber 3b is preferably made up of several parts, which are also in 4 and 5 as items and in 1 to 3 to be seen in the assembly.

• – ein aus Metall, vorzugsweise aus Edelstahl, oder aus Kunststoff bestehender Tastenknopf 10 mit einer Durchgrifföffnung 11 für ein Werkzeug, der bevorzugt einen rechteckigen oder – wie dargestellt – quadratischen Umriss aufweist;
• – eine optional vorhandene Dichtung 12, insbesondere ein elastomerer O-Ring;
• – ein erstes Sperrteil 13 des Sperrmechanismus S, mit dem die Einnahme der Freigabestellung der Tasteinrichtung T blockierbar ist, wobei das Teil 13 in seiner oberen Deckfläche eine – im dargestellten Fall sechskantige – Eingrifföffnung 14 für ein Werkzeug, wie einen Inbusschlüssel, und – optional – eine, insbesondere ringförmige, nicht näher bezeichnete Nut zur Einlage der Dichtung 12 aufweist;
• – eine Druckfeder 15 des Sperrmechanismus S;
• – ein zweites Sperrteil 16 des Sperrmechanismus S, mit dem die Einnahme der Freigabestellung der Tasteinrichtung T blockierbar ist;
• – ein Einsatzteil 17 und
• – eine Rückstellfeder 18 für den Tastenknopf 10, die dazu dient, die Tasteinrichtung T nach einer Bedienung, also nachdem die Tasteinrichtung T durch Drücken des Tastknopfes 10 aus ihrer Ruhestellung (1, 7) – z. B. zum Klingeln – in ihre Aktivstellung (2) gebracht wurde, wieder in die Ruhestellung (1, 7) zurückzubringen.

According to 6 are these, from top to bottom:

• - One made of metal, preferably made of stainless steel, or made of plastic key button 10 with a passage opening 11 for a tool, which preferably has a rectangular or - as shown - square outline;
• - an optional seal 12 , in particular an elastomeric O-ring;
• - A first locking part 13 the locking mechanism S, with the receipt of the release position of the sensing device T is blocked, the part 13 in its upper top surface a - in the case illustrated hexagonal - engagement opening 14 for a tool, such as an Allen key, and - optionally - a, in particular annular, unspecified groove for inserting the seal 12 having;
• - a compression spring 15 the locking mechanism S;
• - A second locking part 16 the locking mechanism S, with the receipt of the release position of the sensing device T is blocked;
• - an insert 17 and
• - a return spring 18 for the key button 10 , which serves the sensing device T after an operation, ie after the sensing device T by pressing the button 10 from their rest position ( 1 . 7 ) - z. B. to ring - in their active position ( 2 ) was brought back into the idle position ( 1 . 7 ) return.

Below the sensing device T is a printed circuit board 20 arranged on the switch contacts 21 when pressing the button 10 by acting as a switching plunger second locking part 16 be switched. The contacts 21 may be in the sense of a moisture-proof enclosure preferably by a - not visible - on the circuit board 20 Covered plastic film to be covered.

The key button 10 can preferably - what in 6 not shown, however 4 and 5 can be seen - with the insert 17 , in particular with a flange, to the outline of the key button 10 adjusted border 17a of the insert part 17 , preferably via a double-adhesive tape 22 to be glued.

The gluing of the button button 10 and the insert part 17 takes place with the interposition of the two locking parts 13 . 16 , between which in turn the compression spring 15 the locking mechanism S is chambered. The two locking parts 13 . 16 have for this purpose corresponding, centrally arranged spring holders 13a ( 1 to 3 . 5 ) 16a ( 1 to 4 . 6 ) on. The spring holder 13a of the first blocking part 13 is there as a pen, the spring holder 16a of the second blocking part 16 is designed as a recording.

In particular 4 to 6 show, the second, in the installed state in the insert part 17 lower blocking part 16 for correct positioning and positioning after positioning in a ring opening 17b of the insert part 17 outer guide grooves 16b on, those on the inner circumference of the ring opening 17b of the insert part 17 complementary inner guide projections 17c assigned. The outer guide grooves 16b of the second blocking part 16 are on the top side by a bridge 16c closed, leaving the second locking part 16 not down from the insert 17 can fall out.

The insert part 17 has a groove on the underside 17d for receiving the return spring 18 for the key button 10 on how this particular 1 . 2 and 5 clarify. The return spring 18 is also designed as a compression spring, for example as a helical spring, and is supported in the installed state, ie, when the insert part 17 in the case 3 , in particular in the associated housing chamber 3b , is used on the ground 6 or preferably but on the circuit board 20 off, like this 2 particularly clearly illustrated. Thus the insert part 17 if it is in his housing chamber 3b is used, can be placed in the correct position and against rotation, has the insert 17 on the outside outer guide projections 17e on top of those in the second housing chamber 3b the housing according to the invention 3 corresponding, ie positively cooperating, wall guides 30 are assigned as this particular from 1 . 2 and 4 evident. It can also be provided that the insert part 17 in the housing chamber 3b is locked, including in the housing according to the invention 3 corresponding - not designated - locking elements are present.

At rest ( 1 ) and in the active position ( 2 ) of the sensing device T is the locking mechanism S in a blocking position, in the release position ( 3 ) of the sensing device T is the locking mechanism S in an unlocked position. The blocking position and the unlocking position are in each case by the two locking parts 13 . 16 Are defined.

To make this possible, the two locking parts 13 . 16 designed according to the type of a dog clutch, ie both the first locking part 13 has at least one claw 13b , Preferably - as shown - three against each other by 120 ° offset, claws 13b , on, as well as the second blocking part 16 for which the claws with the reference numeral 16d are designated.

In the blocking position are each associated claws 13b . 16d at almost relaxed compression spring 15 on each other while in the unlocked position the claws 13b . 16d lie next to each other or, in particular form-fitting, interlock.

The locking mechanism S can thereby by a rotation of the first locking part 13 about its longitudinal axis - in the illustrated case by an angular amount of about 60 ° - are brought from the locked position to the unlocked position. So if the locking mechanism S is in its locked position ( 1 . 2 . 7 ), can through the access opening 11 in the key button 10 in the engagement opening 14 in the first blocking part 13 a tool, such as an Allen key, guided, by means of which the rotation is performed. The in the locked position on the claws 16d of the second blocking part 16 standing claws 13b of the first blocking part 13 be by the rotation of the claws 16d of the second blocking part 16 moved down so they are in between the claws 16d lying, unspecified, spaces can slide, as well as inversely with the claws 16d of the second blocking part 16 can happen. The two locking parts 13 . 16 are still through the pressure spring held between them 15 braced against each other, but can against the force of the compression spring 15 be compressed, so by pressing the button 10 the sensing device T in their in 3 shown release position can be brought in the key button 10 in the second housing chamber 3b below the slot-like opening 2 the receptacle A for the label carrier 1 to come to rest.

In this position you can press the button 10 the label carrier 1 can be provided with a first or a new label, or an existing label can be removed. For this purpose, the label carrier 1 in particular with the aid of a tool, such as a screwdriver, attached to a specially designed tool attachment 40 at the edge of the label holder 1b can attack, in its longitudinal direction from the receptacle A at least partially into the second housing chamber 3b , preferably, when the label carrier 1 is flexible, but also be completely pulled out of the receptacle A. Now, for example, in the label holder 1b a label 1a be inserted or an existing label 1a be removed or replaced. For better recording of the label 1a indicates the label holder 1b preferably a circumferential upstanding edge 41 on how this particular 4 shows.

After that, the label carrier 1 be reversed again in its recording A, the key button 10 after relief under the action of the springs 13 . 18 its position corresponding to the rest position of the sensing device T ( 1 ) again. The locking mechanism S must now still by reverse rotation of the first locking part 13 be returned by means of the tool in its locked position in which the claws 13b . 16d the two locking parts 13 . 16 stand on each other.

This problem-free - especially without over-rotation of the locking part 13 , So in the present case by more than 60 °, in its next unlocked position - succeed and thus the locking position is sufficiently secured against spontaneous cancellation by external influences, the jaws 13b . 16d the two locking parts 13 . 16 have a further special design. Thus, the plan view of the second locking part 16 in 6 that each in the surface of each claw 16d an arcuate guide groove 16e is introduced, which is open on one side and on the other side by a crosspiece 16f closed is. In this guide groove 16e grips a guide nose 13c the claw 13b of the first blocking part 13 a, that of a main body 13d the claw 13 in the axial direction - in 5 and 6 denoted by XX - protrudes. When turning back the first locking part 13 in the blocking position beats in the guide 16e guided guide nose 13d at the crossbar 16f on, causing the blocking part 13 is prevented from over-rotation and the locking position of the locking mechanism S advantageously undergoes an additional positive locking.

With regard to the second blocking part 16 is also to mention that as a spring holder 16a provided receptacle below as a ram part 16g to activate the contact 21 can be trained, like this 2 shows.

Especially the above-described embodiment of the sensing device T with the locking mechanism S represent technical measures by which the Professional the push-button device according to the invention can supplement with the housing according to the invention, without departing from the scope of the invention.

4 and 5 illustrate how tasks according to a simple assembly and disassembly of the pressure sensing device according to the invention with the housing according to the invention 3 where nameplates are required in large numbers on a bell, letterbox and / or intercom. For example, for several bell buttons a single circuit board 20 be applied, on the several, for example, a specific predetermined number, contacts 21 are arranged. This can - as in particular from 5 shows - be provided that the circuit board 20 end by an interface 50 is completed, which corresponds to the respective contacts number of connection pins 51 contains.

This flange edge 8a will be between the case 3 , in particular between the outer wall approach 64 , on the wall piece 7c is formed, that the receptacle A closes, and a front panel 70 jammed. The front panel 70 In this case, preferably encompasses the outside of the entire pressure sensing device according to the invention, preferably also several - as described above - juxtaposed Drucktastvorrichtungen invention, and preferably forms together with the cover plate 8th and the sensing device T a flat surface. On the side of the sensing device T is the front panel 70 while on the case 3 , in particular on the formed on this side outer wall approach 65 on the housing transverse wall 7b , on. It would of course also be possible for the cover plate 8th and / or the key button 10 the sensing device T, if desired, relative to the front panel 70 jump forward or backward. The front panel 70 into which, for example, in a door station further devices, such as microphones, speakers, video cameras or the like can be embedded, is - as shown - on its underside with fasteners 71 , as screw or locking bolts provided, by means of which they in turn can be mounted on a mounting base, not shown, in turn.

At the housing according to the invention 3 are additional - like 4 and 5 show - in the wall approaches 64 . 65 mounting holes 66 introduced, for example, for a screw connection of the housing 3 can be used on a base like this 8th shows. It is in particular a perspective view of an assembly example of a pressure sensing device according to the invention with a plurality of housings according to the invention 3 of which two are figuratively shown. The representation shows a not yet installed, but assembled state of the parts again.
