Definitions
- the invention relates to a pear and multi-button with at least one function button arranged on a button housing and one from an outlet opening of the connecting line leading out of the button housing.
- Buttons of this type are known (cf. DIN 41050 Part 1, terms relating to nurse call technology). They are mostly used in the medical and nursing sector, where they allow a bedridden patient, e.g. from the bed to call the nursing staff. In order to have the button clearly visible in the patient's grip area, the button is usually operated using a holding element attached to its housing, e.g. hung from a hook or loop above the bed (see e.g. DE-U-9 204 051). However, such a holding element is generally not adjustable in length, so that the push button is often knotted with its connecting cable to a handle hanging above the bed as an erection aid.
- the object of the invention is therefore to provide a button that can be hung length-adjustable on its connecting cable.
- the object is achieved in a pear and multiple button according to the preamble of claim 1 in that the button housing is provided with a clamp holder for receiving a portion of the connecting line laid to a loop extending from the outlet opening to the holder.
- a loop can thus be formed from the connecting line, which e.g. is guided around the handle of a hospital bed to the push button housing and is clamped there in the clamping bracket, so that the push button hangs on the handle by means of the loop.
- the design of a button according to the invention allows a continuously adjustable hanging of the button with the connecting line without an additional device for hanging, such as. a hook is needed.
- the clamp bracket is designed such that it releases the connecting cable when it is pulled.
- the button can thus be suspended by means of a loop formed by inserting a section of the connecting line into the clamp holder of the button housing without the risk that the connecting line loop slips out of the holder.
- the clamp holder of the recess releases the connecting line, which prevents damage to the connecting line due to excessive tensile stress.
- the clamping bracket is sunk in an outer surface of the push button housing.
- the clamp holder is a groove-like depression which is introduced into the surface of the push button housing, the cross section of the depression substantially corresponding in shape and size to the cross section of the connecting line, so that it can be inserted into the recess comfortably, but without play.
- the depression also has a holding device, which holds the connecting line inserted in sections in the depression in the depression and releases it when the connection line is pulled.
- the groove-like recess has a U-shape, the ends of the legs of the U-shape adjoining an end face of the push button housing, in particular the end face provided with the outlet opening of the connecting line.
- molded lugs are provided as a holding device on the recess.
- a holding clip is arranged as a holding device, in particular in the region of curvature of the U-shaped recess.
- a button (1) according to the invention is described below with reference to FIGS. 1 and 2.
- the button (1) comprises a button housing (2) with a connecting line (3) opening into the housing (2).
- the button housing (2) has a flat, elongated, essentially rectangular shape and is about the size of a palm.
- Function keys (61, 62) are arranged on an upper side (21) of the push button housing (2), with the aid of which room lighting (function key 61) and reading light (function key 62) can be switched on and off.
- the corner (8) of the push button housing (2) located at the bottom right in the illustration in FIG. 1 is greatly rounded. If the button (1) is gripped in the position shown with the right hand in order to press one of the function buttons (61, 62) with its thumb, the ergonomically advantageous rounding (8) comes to rest in the ball of the hand, so that the rounding off (8) the handiness of the button (1) is improved.
- an approximately circular nail-shaped, substantially circular arc-shaped recess (23) is formed, which passes through to the underside (22) of the push button housing (2).
- a call button (5) is arranged in this recess (23). The outer edge of the call button (5) continues the contour of the rounding (8).
- the call button (5) is pressed by a non-radial button, for example in the sense of Arrow (P1).
- the button (1) In order to be able to operate the call button (5) comfortably with one hand, preferably the right hand, the button (1) must be moved from the position shown in FIG.
- Fig. 4 illustrates the arrangement and design of the recess (23) and the call button (5) arranged therein in a transverse side view according to the arrow (IV) of Fig. 2.
- the continuous recess (23) extends from the top (21) to Bottom (22) of the push button housing (2).
- the call button (5) has essentially the shape of a disc with rounded edges. It is visible both from the top (21), the bottom (22) and the short transverse side (28).
- the connecting line (3) opens at the end face (21) through the opening (29) into the push button housing (2) (cf. FIG. 2).
- the button housing (2) has an essentially U-shaped recess (24) on its underside (22).
- the cross-section of the recess (24) is shaped such that the connecting line (3) can be inserted in sections in it. It is arranged in such a way that the legs of its U-shape are perpendicular to the end face (27) of the push button housing (2).
- the connecting cable (3) e.g. a loop (30) is formed around the handle of a hospital bed, which is closed by inserting the connecting line (3) into the recess (24).
- the recess (24) has outlet openings (26) with a widened cross section and retaining lugs (25).
- the connecting line (3) can accordingly be inserted through the openings (26) into the recess (24), where it is held by the protruding retaining lugs (25).
- FIG. 3 A view of the end face (27) of the push button housing (2) according to the arrow (III) is shown in FIG. 3.
- the recess (24) on the underside (22) of the push button housing (2) borders with its cross-sectional openings (26) on the end face (27).
- flush retaining lugs (25) are formed at the outer end of the openings (26) with the underside (22) of the housing (2).
- the distance between a holding nose tip protruding into the opening (26) and the opposite edge of the widened opening (26) is so large that the cross section of the connecting line (3) can be carried out.
- the depth of the recess (24) is selected so that the completely inserted connecting line slides with its cross section under the retaining lugs (25), and is thus held by the latter in the recess (24).
- the underside of the retaining lugs (25) acting on the connecting line (3) is rounded, so that when the connecting line (3) is pulled, it can slide obliquely upwards along the underside of the retaining lugs (25) and is easily released. This can be supported by the fact that the walls of the recess (24) are slightly beveled towards the inside of the U-shape.
- FIG. 5 shows a section of the bottom of the button housing (22) according to the section (V) of FIG. 2 in an enlarged view.
- the depression in FIG. 5 has a retaining clip (7) which covers and clamps the connecting line (3) inserted into the depression (24) in the region of the curvature of the U-shape.
- the retaining clip (7) consists of two clamping surfaces, of which the clamping surface (7a) lying on the underside (22) of the push button housing (2) is shown in the illustration in FIG. 5, and an elastic element connecting these two clamping surfaces, e.g. a coil spring.
- the retaining clip (7) is so integrated in the push button housing (2) that the outer clamping surface (7a) is flush with the surface of the housing underside (22) and the other, not shown clamping surface parallel to the first clamping surface (7a) on the The interior of the housing facing deep end of the recess (24).
- the two clamping surfaces advantageously protrude with clamping elements, e.g. Clamping lugs into the cross section of the recess (24).
- the connecting line (3) If the connecting line (3) is pushed into the recess (24), it meets the clamping lugs of the clamping surfaces, as a result of which the clamping surfaces are pressed apart. Due to the pre-tension exerted by the elastic element Clamping lugs of the retaining clip (7) connect the connecting line in the U-shaped area of curvature and clamp it.
- the bias of the elastic element is selected so that the connecting line (3) is held on the one hand in the recess (24), but on the other hand is easily released by the retaining clip (7) when the cable acts on the connecting line.
- the recess (24) in the push button housing (2) and the holding device holding the connecting line (3) can of course also be designed in such a way that the connecting line is not completely released when the train acts and slips out of the recess (24), but rather with less Friction can be pulled through the recess (24) in the longitudinal direction. Pulling on the button or on the connecting line of the button thus yields and lengthens the loop without the connecting line being subjected to wear and tear.
Abstract
Description
Die Erfindung betrifft einen Birn- und Mehrfachtaster mit wenigstens einer an einem Tastergehäuse angeordneten Funktionstaste und einer aus einer Austrittsöffnung des von dem Tastergehäuses hinausgeführten Anschlußleitung.The invention relates to a pear and multi-button with at least one function button arranged on a button housing and one from an outlet opening of the connecting line leading out of the button housing.
Taster dieser Art sind bekannt (vgl. DIN 41050 Teil 1, Begriffe zur Lichtruftechnik). Sie finden zumeist im Kranken- und Pflegebereich Verwendung, wo sie einem bettlägrigen Patienten erlauben, vom Bett aus z.B. das Pflegepersonal zu rufen. Um den Taster gut sichtbar im Griffbereich des Patienten zu haben, wird der Taster gewöhnlicherweise mittels einem an seinem Gehäuse angebrachten Halteelement, z.B. einem Haken oder einer Schlaufe über dem Krankenbett aufgehängt (siehe z.B. DE-U-9 204 051). Ein solches Halteelement ist in der Regel jedoch nicht längenverstellbar, so daß der Taster oft mit seinem Anschlußkabel an einem als Aufrichthilfe über dem Bett hängenden Haltegriff angeknotet wird.Buttons of this type are known (cf. DIN 41050 Part 1, terms relating to nurse call technology). They are mostly used in the medical and nursing sector, where they allow a bedridden patient, e.g. from the bed to call the nursing staff. In order to have the button clearly visible in the patient's grip area, the button is usually operated using a holding element attached to its housing, e.g. hung from a hook or loop above the bed (see e.g. DE-U-9 204 051). However, such a holding element is generally not adjustable in length, so that the push button is often knotted with its connecting cable to a handle hanging above the bed as an erection aid.
Aufgabe der Erfindung ist es daher, einen Taster zu schaffen, der längenverstellbar an seinem Anschlußkabel aufgehängt werden kann.The object of the invention is therefore to provide a button that can be hung length-adjustable on its connecting cable.
Die Aufgabe wird in einem Birn- und Mehrfachtaster gemäß dem Oberbegriff des Anspruchs 1 dadurch gelöst, daß das Tastergehäuse mit einer Klemmhalterung zum Aufnehmen eines Abschnittes der zu einer sich von der Austrittsöffnung bis zur Halterung erstreckenden Schlaufe gelegten Anschlußleitung versehen ist.The object is achieved in a pear and multiple button according to the preamble of claim 1 in that the button housing is provided with a clamp holder for receiving a portion of the connecting line laid to a loop extending from the outlet opening to the holder.
Aus der Anschlußleitung kann somit eine Schlaufe gebildet werden, welche z.B. um den Haltegriff eines Krankenbetts herum zum Tastergehäuse geführt und dort in die Klemmhalterung eingeklemmt wird, so daß der Taster mittels der Schlaufe an dem Haltegriff hängt. Die erfindungsgemäße Ausführung eines Tasters gestattet ein stufenlos einstellbares Aufhängen des Tasters mit der Anschlußleitung, ohne daß eine zusätzliche Einrichtung zum Aufhängen, wie z.B. ein Haken benötigt wird.A loop can thus be formed from the connecting line, which e.g. is guided around the handle of a hospital bed to the push button housing and is clamped there in the clamping bracket, so that the push button hangs on the handle by means of the loop. The design of a button according to the invention allows a continuously adjustable hanging of the button with the connecting line without an additional device for hanging, such as. a hook is needed.
In vorteilhafter Ausgestaltung der Erfindung ist die Klemmhalterung derart ausgeführt, daß sie bei Zug auf die Anschlußleitung diese freigibt. Der Taster kann somit mittels einer durch Einlegen eines Abschnitts der Anschlußleitung in die Klemmhalterung des Tastergehäuses gebildeten Schlaufe aufgehängt werden, ohne daß die Gefahr besteht, daß die Anschlußleitungsschlaufe aus der Halterung herausrutscht. Sobald an dem Taster jedoch gezogen wird, gibt die Klemmhalterung der Vertiefung die Anschlußleitung frei, wodurch eine Beschädigung der Anschlußleitung aufgrund übermäßiger Zugbeanspruchung vermieden wird.In an advantageous embodiment of the invention, the clamp bracket is designed such that it releases the connecting cable when it is pulled. The button can thus be suspended by means of a loop formed by inserting a section of the connecting line into the clamp holder of the button housing without the risk that the connecting line loop slips out of the holder. However, as soon as the button is pulled, the clamp holder of the recess releases the connecting line, which prevents damage to the connecting line due to excessive tensile stress.
In weiterer Ausgestaltung der Erfindung ist die Klemmhalterung versenkt in einer Außenfläche des Tastergehäuses angeordnet. Eine solche versenkte Anordnung der Klemmhalterung ohne über das Tastergehäuse hinausragende Teile wirkt sich vorteilhaft auf die Handhabung des Tasters aus.In a further embodiment of the invention, the clamping bracket is sunk in an outer surface of the push button housing. Such a recessed arrangement of the clamp holder without parts projecting beyond the push button housing has an advantageous effect on the handling of the push button.
In vorteilhafter Ausführung ist die Klemmhalterung eine in die Oberfläche des Tastergehäuses eingebrachte nutartige Vertiefung, wobei der Querschnitt der Vertiefung in Form und Größe im wesentlichen dem Querschnitt der Anschlußleitung entspricht, so daß diese bequem, aber ohne Spiel in die Vertiefung eingelegt werden kann. Die Vertiefung verfügt weiter über eine Halteeinrichtung, welche die abschnittsweise in die Vertiefung eingelegte Anschlußleitung in der Vertiefung hilt und bei Zug auf die Anschlußleitung freigibt.In an advantageous embodiment, the clamp holder is a groove-like depression which is introduced into the surface of the push button housing, the cross section of the depression substantially corresponding in shape and size to the cross section of the connecting line, so that it can be inserted into the recess comfortably, but without play. The depression also has a holding device, which holds the connecting line inserted in sections in the depression in the depression and releases it when the connection line is pulled.
In vorteilhafter Ausführung der Erfindung verfügt die nutartige Vertiefung über eine U-Form, wobei die Schenkel der U-Form mit ihren Enden an einer Stirnseite des Tastergehäuses, insbesondere an der mit der Austrittsöffnung der Anschlußleitung versehenen Stirnseite angrenzen.In an advantageous embodiment of the invention, the groove-like recess has a U-shape, the ends of the legs of the U-shape adjoining an end face of the push button housing, in particular the end face provided with the outlet opening of the connecting line.
In Ausgestaltung der Erfindung sind als Halteeinrichtung an der Vertiefung angeformte Haltenasen vorgesehen.In an embodiment of the invention, molded lugs are provided as a holding device on the recess.
In einer anderen Ausgestaltung der Erfindung ist als Halteeinrichtung eine Halteklammer, insbesondere im Krümmungsbereich der U-förmigen Vertiefung angeordnet.In another embodiment of the invention, a holding clip is arranged as a holding device, in particular in the region of curvature of the U-shaped recess.

Ein erfindungsgemäßer Taster (1) wird im folgenden unter Bezugnahme auf die Fig. 1 und 2 beschrieben. Der Taster (1) umfaßt ein Tastergehäuse (2) mit einer in das Gehäuse (2) mündenden Anschlußleitung (3). Das Tastergehäuse (2) besitzt eine flache, längliche, im wesentlichen rechteckige Form und ist etwa handtellergroß. Auf einer Oberseite (21) des Tastergehäuses (2) sind Funktionstasten (61, 62) angeordnet, mit deren Hilfe eine Zimmerbeleuchtung (Funktionstaste 61) und Leseleuchte (Funktionstaste 62) ein- und ausgeschaltet werden können.A button (1) according to the invention is described below with reference to FIGS. 1 and 2. The button (1) comprises a button housing (2) with a connecting line (3) opening into the housing (2). The button housing (2) has a flat, elongated, essentially rectangular shape and is about the size of a palm. Function keys (61, 62) are arranged on an upper side (21) of the push button housing (2), with the aid of which room lighting (function key 61) and reading light (function key 62) can be switched on and off.
Die in der Darstellung der Fig. 1 rechts unten liegende Ecke (8) des Tastergehäuses (2) ist stark abgerundet. Wird der Taster (1) in der gezeigten Position mit der rechten Hand gegriffen, um mit deren Daumen eine der Funktionstasten (61, 62) zu betätigen, kommt im Handballen somit die ergonomisch vorteilhafte Abrundung (8) zu liegen, so daß durch die Abrundung (8) die Handlichkeit des Tasters (1) verbessert wird.The corner (8) of the push button housing (2) located at the bottom right in the illustration in FIG. 1 is greatly rounded. If the button (1) is gripped in the position shown with the right hand in order to press one of the function buttons (61, 62) with its thumb, the ergonomically advantageous rounding (8) comes to rest in the ball of the hand, so that the rounding off (8) the handiness of the button (1) is improved.
In der Abrundung (8) ist eine etwa daumennagelgroße, im wesentlichen kreisbogenförmige Ausnehmung (23) ausgeformt, welche zur Unterseite (22) des Tastergehäuses (2) durchreicht. In dieser Ausnehmung (23) ist eine Ruftaste (5) angeordnet. Die Ruftaste (5) führt mit ihrer außenliegenden Kante die Kontur der Abrundung (8) fort. Um ein nicht-beabsichtigtes Betätigen der Ruftaste (5) zu verhindern, insbesondere wenn diese in der in der Fig. 1 dargestellten Position am Handballen der Bedienerhand zu liegen kommt, ist die Ruftaste (5) durch nicht-radiales Drücken, z.B. im Sinne des Pfeiles (P1), zu betätigen. Um die Ruftaste (5) daher bequem mit einer Hand, vorzugsweise der rechten Hand, bedienen zu können, muß der Taster (1) von der in der Fig. 1 dargestellten Position in die in der Fig. 2 dargestellten Position gebracht werden. Dies erfolgt vorteilhafterweise durch ein Schwenken des Tastergehäuses (2) um dessen Stirnseite (27). In der in der Fig. 2 dargestellten Position kann das Tastergehäuse (2) dann bequem mit der rechten Hand gegriffen werden, wobei der Daumen die Ruftaste (5) beaufschlägt. Auch in dieser Griffposition wirkt sich die Abrundung (8) des Gehäuses (2) ergonomisch vorteilhaft aus, da sie im wesentlichen der Krümmung des entspannten Daumens entspricht. Durch Einwärtsbewegen des Daumens wird dann die Ruftaste (5) im Sinne des Pfeiles (P1) betätigt. Um die Ruftaste (5) auch bei Dunkelheit einfach finden zu können, ist diese dauerglimmend oder fluoreszierend ausgeführt. Sobald sie erfolgreich betätigt wurde, leuchtet sie zur Rufbestätigung hell auf.In the rounding (8), an approximately circular nail-shaped, substantially circular arc-shaped recess (23) is formed, which passes through to the underside (22) of the push button housing (2). A call button (5) is arranged in this recess (23). The outer edge of the call button (5) continues the contour of the rounding (8). In order to prevent unintentional actuation of the call button (5), in particular if it comes to rest on the palm of the operator's hand in the position shown in FIG. 1, the call button (5) is pressed by a non-radial button, for example in the sense of Arrow (P1). In order to be able to operate the call button (5) comfortably with one hand, preferably the right hand, the button (1) must be moved from the position shown in FIG. 1 to the position shown in FIG. 2. This is advantageously done by pivoting the push button housing (2) around its end face (27). In the position shown in FIG. 2, the push button housing (2) can then be comfortably gripped with the right hand, with the thumb pressing the call button (5). Also in this grip position, the rounding (8) of the housing (2) has an ergonomically advantageous effect, since it essentially corresponds to the curvature of the relaxed thumb. The call button (5) is then actuated in the direction of the arrow (P1) by moving the thumb inwards. In order to be able to find the call button (5) easily even in the dark, it is designed to be permanently glowing or fluorescent. As soon as it has been operated successfully, it lights up brightly to confirm the call.
Fig. 4 veranschaulicht Anordnung und Ausgestaltung der Ausnehmung (23) und der in dieser angeordneten Ruftaste (5) in einer Querseitenansicht gemäß dem Pfeil (IV) der Fig. 2. Die durchgehende Ausnehmung (23) reicht von der Oberseite (21) bis zur Unterseite (22) des Tastergehäuses (2). Die Ruftaste (5) besitzt im wesentlichen die Form einer Scheibe mit abgerundeten Kanten. Sie ist sowohl von der Oberseite (21), der Unterseite (22) als auch von der kurzen Querseite (28) her sichtbar.Fig. 4 illustrates the arrangement and design of the recess (23) and the call button (5) arranged therein in a transverse side view according to the arrow (IV) of Fig. 2. The continuous recess (23) extends from the top (21) to Bottom (22) of the push button housing (2). The call button (5) has essentially the shape of a disc with rounded edges. It is visible both from the top (21), the bottom (22) and the short transverse side (28).
Die Anschlußleitung (3) mündet an der Stirnseite (21) durch die Öffnung (29) in das Tastergehäuse (2) (vgl. Fig. 2). Das Tastergehäuse (2) weist an seiner Unterseite (22) eine im wesentlichen U-förmige Vertiefung (24) auf. Die Vertiefung (24) ist dabei in ihrem Querschnitt derart ausgeformt, daß die Anschlußleitung (3) abschnittsweise darin eingeführt werden kann. Sie ist so angeordnet, daß die Schenkel ihrer U-Form senkrecht an der Stirnseite (27) des Tastergehäuses (2) angrenzen. Mit der Anschlußleitung (3) kann somit z.B. um den Haltegriff eines Krankenbetts eine Schlaufe (30) geformt werden, die durch Einführen der Anschlußleitung (3) in die Vertiefung (24) geschlossen wird. An ihrem stirnseitigen Ende verfügt die Vertiefung (24) über Austrittsöffnungen (26) verbreiterten Querschnitts sowie über Haltenasen (25). Die Anschlußleitung (3) kann demgemäß durch die Öffnungen (26) in die Vertiefung (24) eingesetzt werden, wo sie durch die überstehenden Haltenasen (25) gehalten wird.The connecting line (3) opens at the end face (21) through the opening (29) into the push button housing (2) (cf. FIG. 2). The button housing (2) has an essentially U-shaped recess (24) on its underside (22). The cross-section of the recess (24) is shaped such that the connecting line (3) can be inserted in sections in it. It is arranged in such a way that the legs of its U-shape are perpendicular to the end face (27) of the push button housing (2). With the connecting cable (3), e.g. a loop (30) is formed around the handle of a hospital bed, which is closed by inserting the connecting line (3) into the recess (24). At its front end, the recess (24) has outlet openings (26) with a widened cross section and retaining lugs (25). The connecting line (3) can accordingly be inserted through the openings (26) into the recess (24), where it is held by the protruding retaining lugs (25).
Eine Sicht auf die Stirnseite (27) des Tastergehäuses (2) gemäß dem Pfeil (III) ist in der Fig. 3 dargestellt. Die Vertiefung (24) auf der Unterseite (22) des Tastergehäuses (2) grenzt mit ihren querschnittsverbreiterten Öffnungen (26) an die Stirnseite (27). An dem äußeren Ende der Öffnungen (26) sind mit der Unterseite (22) des Gehäuses (2) bündige Haltenasen (25) angeformt. Der Abstand zwischen einer in die Öffnung (26) hineinragenden Haltenasenspitze zu der ihr gegenüberliegenden Kante der verbreiterten Öffnung (26) ist jeweils so groß, daß der Querschnitt der Anschlußleitung (3) durchgeführt werden kann.A view of the end face (27) of the push button housing (2) according to the arrow (III) is shown in FIG. 3. The recess (24) on the underside (22) of the push button housing (2) borders with its cross-sectional openings (26) on the end face (27). At the outer end of the openings (26) with the underside (22) of the housing (2) flush retaining lugs (25) are formed. The distance between a holding nose tip protruding into the opening (26) and the opposite edge of the widened opening (26) is so large that the cross section of the connecting line (3) can be carried out.
Die Tiefe der Vertiefung (24) ist so gewählt, daß die ganz eingeführte Anschlußleitung mit ihrem Querschnitt unter die Haltenasen (25) rutscht, und somit von diesen in der Vertiefung (24) gehalten wird. Die die Anschlußleitung (3) beaufschlagende Unterseite der Haltenasen (25) ist abgerundet, so daß bei Zug auf die Anschlußleitung (3) diese entlang der Unterseite der Haltenasen (25) schräg nach oben rutschen kann und leicht freigegeben wird. Dies kann noch dadurch unterstützt werden, daß die Wände der Vertiefung (24) zum Innern der U-Form hin leicht abgeschrägt sind.The depth of the recess (24) is selected so that the completely inserted connecting line slides with its cross section under the retaining lugs (25), and is thus held by the latter in the recess (24). The underside of the retaining lugs (25) acting on the connecting line (3) is rounded, so that when the connecting line (3) is pulled, it can slide obliquely upwards along the underside of the retaining lugs (25) and is easily released. This can be supported by the fact that the walls of the recess (24) are slightly beveled towards the inside of the U-shape.
Eine vorteilhafte Ausgestaltung der Vertiefung (24) ist in Fig. 5 dargestellt. Fig. 5 zeigt dazu einen Ausschnitt der Tastergehäuse-Unterseite (22) gemäß dem Ausschnitt (V) der Fig. 2 in Vergrößerung. Im Unterschied zu der Vertiefung in Fig. 2 weist die Vertiefung der Fig. 5 eine Halteklammer (7) auf, welche die in die Vertiefung (24) eingelegte Anschlußleitung (3) im Bereich der Krümmung der U-Form bedeckt und festklemmt.An advantageous embodiment of the recess (24) is shown in FIG. 5. 5 shows a section of the bottom of the button housing (22) according to the section (V) of FIG. 2 in an enlarged view. In contrast to the depression in FIG. 2, the depression in FIG. 5 has a retaining clip (7) which covers and clamps the connecting line (3) inserted into the depression (24) in the region of the curvature of the U-shape.
Die Halteklammer (7) besteht aus zwei Klemmflächen, von denen in der Darstellung der Fig. 5 die auf der Unterseite (22) des Tastergehäuses (2) liegende Klemmfläche (7a) gezeigt ist, und einem diese beiden Klemmflächen miteinander verbindenden elastischen Element, z.B. einer Spiralfeder. Die Halteklammer (7) ist dabei so in das Tastergehäuse (2) integriert, daß die außenliegende Klemmfläche (7a) bündig mit der Fläche der Gehäuseunterseite (22) abschließt und die andere, nicht dargestellte Klemmfläche parallel zur ersten Klemmfläche (7a) an dem zum Gehäuseinneren weisenden tiefen Ende der Vertiefung (24) anliegt. Vorteilhafterweise ragen die beiden Klemmflächen dabei mit Klemmelementen, z.B. Klemmnasen in den Querschnitt der Vertiefung (24) hinein.The retaining clip (7) consists of two clamping surfaces, of which the clamping surface (7a) lying on the underside (22) of the push button housing (2) is shown in the illustration in FIG. 5, and an elastic element connecting these two clamping surfaces, e.g. a coil spring. The retaining clip (7) is so integrated in the push button housing (2) that the outer clamping surface (7a) is flush with the surface of the housing underside (22) and the other, not shown clamping surface parallel to the first clamping surface (7a) on the The interior of the housing facing deep end of the recess (24). The two clamping surfaces advantageously protrude with clamping elements, e.g. Clamping lugs into the cross section of the recess (24).
Wird die Anschlußleitung (3) in die Vertiefung (24) eingeschoben, so trifft sie auf die Klemmnasen der Klemmflächen, wodurch die Klemmflächen auseinandergedrückt werden. Durch die von dem elastischen Element ausgeübte Vorspannung beaufschlagen die Klemmnasen der Halteklammer (7) die Anschlußleitung in dem U-förmigen Krümmungsbereich und klemmen diese fest. Die Vorspannung des elastischen Elements ist dabei so gewählt, daß die Anschlußleitung (3) einerseits in der Vertiefung (24) festgehalten wird, aber andererseits bei auf die Anschlußleitung einwirkendem Zug leicht von der Halteklammer (7) freigegeben wird.If the connecting line (3) is pushed into the recess (24), it meets the clamping lugs of the clamping surfaces, as a result of which the clamping surfaces are pressed apart. Due to the pre-tension exerted by the elastic element Clamping lugs of the retaining clip (7) connect the connecting line in the U-shaped area of curvature and clamp it. The bias of the elastic element is selected so that the connecting line (3) is held on the one hand in the recess (24), but on the other hand is easily released by the retaining clip (7) when the cable acts on the connecting line.
Die Vertiefung (24) im Tastergehäuse (2) und die die Anschlußleitung (3) festhaltende Halteeinrichtung können selbstverständlich auch so ausgeführt werden, daß die Anschlußleitung bei einwirkendem Zug nicht gänzlich freigegeben wird und aus der Vertiefung (24) herausrutscht, sondern daß sie mit geringer Reibung durch die Vertiefung (24) in Längsrichtung hindurchgezogen werden kann. Ein Ziehen am Taster bzw. an der Anschlußleitung des Tasters bewirkt somit ein Nachgeben und eine Verlängerung der Schlaufe, ohne daß die Anschlußleitung verschleißgefährdend belastet wird.The recess (24) in the push button housing (2) and the holding device holding the connecting line (3) can of course also be designed in such a way that the connecting line is not completely released when the train acts and slips out of the recess (24), but rather with less Friction can be pulled through the recess (24) in the longitudinal direction. Pulling on the button or on the connecting line of the button thus yields and lengthens the loop without the connecting line being subjected to wear and tear.
