Description

Die Erfindung betrifft eine Schutzhülle für elektrisch betriebene Taschengeräte mit einem auf der Vorderseite des Taschengeräts angeordneten Anzeige- und/oder Bedienungsfeld, insbesondere für Taschenrechner, wobei die Schutzhülle der äußeren Form des Taschengerätes angepaßt ist und die wahlweise eine Offenlegung oder Abdeckung des Bedienungs-und ggfs. Anzeigefeldes ermöglicht.The invention relates to a protective cover for electrically operated handheld devices with a display and / or control panel arranged on the front of the handheld device, in particular for pocket calculators, the protective cover being adapted to the external shape of the handheld device and optionally having a disclosure or cover for the operating and possibly Display field enables.

Es sind Schutzhüllen für Taschengeräte der in Frage stehenden Art bekannt, die das Taschengerät auf fünf Seitenflächen vollständig umhüllen. Derartige Schutzhüllen sind also einseitig offen und werden als Stecketuis bezeichnet. Zur Benutzung des Taschengeräts ist es notwendig, dieses aus dem Stecketui vollständig herauszuziehen und dann das leere Stecketui gesondert aufzubewahren bzw. vom Gerät getrennt abzulegen.Protective covers for pocket devices of the type in question are known which completely encase the pocket device on five side surfaces. Such protective covers are therefore open on one side and are called plug cases. To use the pocket device, it is necessary to pull it completely out of the plug-in case and then to store the empty plug-in case separately or to store it separately from the device.

Aus der DE-A-20 19 851 ist eine Schutzhaube für elektrische Rasierapparate bekannt, die aus zwei gleichen, das Gerät überdeckenden, durch Längsteilung der Schutzhaube erhaltenen, miteinander verbundenen Halbschalen aus elastischem Material mit jeweils einer offenen Stirnseite besteht. Die Halbschalen sind mit jeweils einem, von ihren Stoßkanten nach außen abgebogenen umlaufenden Flansch versehen, wobei die Halbschalen an diesen Flanschen miteinander verschweißt sind. Eine solche Schutzhaube eignet sich hervorragend zur Aufbewahrung eines Rasierapparats, also eines Geräts, welches zu seiner Bedienung vollständig von der Schutzhaube getrennt werden muß. Für elektrisch betriebene Geräte, bei denen für die Benutzung lediglich ein Teil des Geräts frei zugänglich sein muß, wie dies beispielsweise bei einem Taschenrechner der Fall ist, sind Etuis dieser Art wenig geeignet.From DE-A-20 19 851 a protective hood for electric shavers is known, which consists of two identical, covering the device, obtained by longitudinal division of the protective hood, interconnected half-shells made of elastic material, each with an open end face. The half-shells are each provided with a circumferential flange which is bent outwards from their abutting edges, the half-shells being welded to one another on these flanges. Such a protective hood is ideally suited for storing a shaving apparatus, that is to say a device which must be completely separated from the protective hood in order to operate it. Cases of this type are not very suitable for electrically operated devices in which only part of the device has to be freely accessible for use, as is the case, for example, with a pocket calculator.

Aus der GB-A-1 444 251 ist eine Schutzhülle aus flexiblem PVC-Material, insbesondere für einen Taschenrechner bekannt, die auf der Vorderseite eine zentrale Öffnung für das Bedienungsfeld des Taschenrechners und mindestens drei mit der Vorderseite verbundene Seitenteile aufweist. An den beiden längeren Seitenteilen sind zwei Laschen angebracht, während an einem kürzeren Seitenteil eine längere Lasche befestigt ist, die die Rückseite des Taschenrechners abdeckt. Diese längere Lasche weist einen ebenfalls laschenförmigen Endabschnitt mit einem darauf befestigten Druckknopf auf, der mit dem Druckknopf einer am anderen kürzeren Seitenteil angebrachten Lasche verbindbar ist. Schließlich its am einen kürzeren Seitenteil eine Lasche zur Abdeckung der Offnung, d.h. des Bedienungsfeldes des Taschenrechners vorgesehen, die mittels eines Druckknopfes, der mit einem entsprechenden Gegen-Drukknopf am Rande der zentralen Öffnung zusammenwirkt, verschlossen werden kann.GB-A-1 444 251 discloses a protective cover made of flexible PVC material, in particular for a calculator, which has a central opening on the front for the control panel of the calculator and at least three side parts connected to the front. Two straps are attached to the two longer side parts, while a longer side is attached to a shorter side part, which covers the back of the calculator. This longer flap has a likewise flap-shaped end section with a push button fastened thereon, which can be connected to the push button of a flap attached to the other shorter side part. Finally, there is a tab on a shorter side part to cover the opening, i.e. the control panel of the calculator is provided, which can be closed by means of a push button which interacts with a corresponding counter push button on the edge of the central opening.

Aus der US-A-3 622 720 ist ein elektrischer Taschenrechner mit einer mit dem Taschenrechner fest verbundenen Abdeckung des Tasten- und des Anzeigefeldes bekannt. Mit dem Freilegen des Tastenfeldes durch Verschieben einer Abdeckplatte in Richtung des Anzeigefeldes wird gleichzeitig das im abgedeckten Zustand versenkte Anzeigefeld ausgefahren und der Geräteschalter mittels einer Hebelübertragung in den EIN-Zustand gebracht. Wird die Abdeckplatte wieder über das Tastenfeld geschoben, so wird zwangsläufig das Anzeigefeld versenkt und der Geräteschalter in den AUS-Zustand gebracht.From US-A-3 622 720 an electrical pocket calculator with a cover of the key and display field which is firmly connected to the pocket calculator is known. When the keypad is exposed by moving a cover plate in the direction of the display panel, the display panel, which is recessed in the covered state, is simultaneously extended and the device switch is brought into the ON state by means of a lever transmission. If the cover plate is pushed over the keypad again, the display panel is inevitably lowered and the device switch is switched to the OFF state.

Aufgabe der vorliegenden Erfindung ist es, eine Schutzhülle für elektrisch betriebene Taschengeräte, insbesondere für Taschenrechner, zu schaffen, die in möglichst wenigen Arbeitsgängen und damit preiswert herstellbar ist, die ein sehr geringes Gewicht aufweist, die vom Taschengerät selbst während der Benutzung des Taschengerätes nicht getrennt aufbewahrt zu werden braucht und die eine unkomplizierte Handhabung von Schutzhülle und Taschengerät gewährleistet.The object of the present invention is to provide a protective cover for electrically operated handheld devices, in particular for pocket calculators, which can be produced in as few operations and therefore inexpensively as possible, and which has a very low weight, which is not separated from the handheld device itself during use of the handheld device needs to be stored and which ensures uncomplicated handling of the protective cover and pocket device.

Diese Aufgabe wird nach der Erfindung durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention by the features of claim 1.

Das Zusammenwirken von Schutzhülle und Taschengerät nach der Erfindung ist besonders vorteilhaft. Die Schutzhülle ist in wenigen Arbeitsgängen und damit preiswert herstellbar, sie weist ein sehr geringes Gewicht auf und kann sowohl bei der Benutzung des Gerätes am Taschengerät verbleiben als auch bei Nichtbenutzung zur Abdeckung sowohl des Bedienungs- als auch des Anzeigefeldes und der verschiedenen, am Taschengerät angebrachten Schalter dienen. Daraus ergibt sich eine besonders einfache und unkomplizierte Handhabung des Taschengerätes zusammen mit der Schutzhülle.The interaction of protective cover and pocket device according to the invention is particularly advantageous. The protective cover can be produced in a few work steps and is therefore inexpensive, it has a very low weight and can remain on the handheld device when the device is in use, as well as when not in use to cover both the control panel and the display panel and the various devices attached to the handheld device Serve switches. This results in a particularly simple and uncomplicated handling of the pocket device together with the protective cover.

In den Figuren 1 bis 6 ist eine Schutzhülle 10 dergestellt, die aus einer Rückwand 11, zwei Längsseitenwänden 12 und 13 und einer Stirnwand 14 besteht. Die Stirnseite 15 ist offen. Von den Längsseitenwänden 12, 13 und der Stirnwand 14 verlaufen in einer Ebene parallel zur Rückwand 11 Führungsleisten 16, 17 und eine Endleiste 18. Diese Leisten erstrecken sich nur um ein geringes Maß nach innen. Die Rückseite 11, die Längsseitenwände 12, 13, die Stirnwand 14 und die umlaufenden Leisten 16, 17, 18 sind aus einem steifelastischen Werkstoff, beispielsweise einem Kunststoff, einteilig hergestellt.In Figures 1 to 6, a protective cover 10 is shown, which consists of a rear wall 11, two longitudinal side walls 12 and 13 and an end wall 14. The end face 15 is open. Guide strips 16, 17 and an end strip 18 run in a plane parallel to the rear wall 11 from the longitudinal side walls 12, 13 and the end wall 14. These strips extend only a small amount inwards. The back 11, the longitudinal side walls 12, 13, the end wall 14 and the circumferential strips 16, 17, 18 are made in one piece from a rigid plastic material, for example a plastic.

Wie die Figuren 1 bis 9 zeigen, läßt sich die Schutzhülle 10 vom Taschengerät 1, im dargestellten Falle einem Taschenrechner, in Pfeilrichtung A, d.h. in ihrer Längsrichtung abziehen und anschließend in entgegengesetzter Richtung in Pfeilrichtung B (Figur 3) wieder auf das Gerät aufschieben, wozu die Schutzhülle vorher in Richtung ihrer Längsachse um 180° gedreht wurde. Bei in dieser Weise aufgeschobener Schutzhülle bleibt, wie in Fig. 4 dargestellt, das Bedienungsfeld 110 des Taschengeräts 1 weitgehend frei, so daß die Tasten auf dem Bedienungsfeld 110 ohne weiteres bedienbar sind. In dieser, in Fig. 4 dargestellten Position greifen lediglich die umlaufenden Leisten 16, 17, 18 in Längs- bzw. Quernuten 101 bzw. 102 am Taschengerät 1 ein und verhindern so, daß die Schutzhülle 10 in Pfeilrichtung C vom Taschengerät 1 abrutscht. Voraussetzung für eine gute Verbindung zwischen Schutzhülle 10 und Taschengerät 1 ist, daß die lichte Weite a und die lichte Höhe b der Schutzhülle den entsprechenden Außenmaßen, d.h. der Breite und der Dicke des Taschengeräts, 1, angepaßt sind.As FIGS. 1 to 9 show, the protective cover 10 can be removed from the pocket device 1, in the case shown a pocket calculator, in the direction of arrow A, i.e. Pull it off in its longitudinal direction and then push it back on the device in the opposite direction in the direction of arrow B (FIG. 3), for which purpose the protective cover was previously rotated by 180 ° in the direction of its longitudinal axis. When the protective cover is pushed on in this way, the control panel 110 of the pocket device 1 remains largely free, as shown in FIG. 4, so that the buttons on the control panel 110 can be operated without further ado. In this position, shown in FIG. 4, only the circumferential strips 16, 17, 18 engage in longitudinal or transverse grooves 101 or 102 on the pocket device 1 and thus prevent the protective cover 10 from sliding off the pocket device 1 in the direction of arrow C. A prerequisite for a good connection between protective cover 10 and pocket device 1 is that the clear width a and the clear height b of the protective cover have the corresponding external dimensions, i.e. the width and thickness of the pocket device, 1, are adapted.

Ein besonderer Vorteil der beschriebenen Schutzhülle 11 besteht darin, daß diese einerseits-wie in Fig. 1 dargestellt-das Bedienungsfeld 110 und das empfindliche Anzeigefeld 120 vor Stößen, vor Verkratzen und vor Verschmutzung schützt, daß jedoch andererseits die Schutzhülle 10 so mit dem Taschengerät 1 verbunden werden kann (Figuren 3 und 4), daß die Schutzhülle 10 die ungehinderte Bedienung des Taschengeräts 1 erlaubt, gleichzeitig aber daran arretiert bleibt, so daß die das Taschengerät 1 benutzende Person keinen besonderen Aufbewahrungsort für die Schutzhülle 10 während einer Rechen-oder Meßoperation benötigt.A particular advantage of the protective cover 11 described is that it protects the control panel 110 and the sensitive display panel 120 from bumps, scratches and contamination, as shown in FIG. 1, but that the protective cover 10 is so attached to the pocket device 1 can be connected (Figures 3 and 4) that the protective cover 10 allows the unhindered operation of the pocket device 1, but remains locked at the same time, so that the person using the pocket device 1 does not need a special storage location for the protective cover 10 during a computing or measuring operation .

Bei den in den Figuren 10, 11 bzw. 11, 12 dargestellten Ausführungsbeispielen sind die Geräte 2 bzw. 3 jeweils mit Führungsleisten 201 bzw. 301 versehen, die in Längsnuten 27 bzw. 37 der Schutzhüllen 20 bzw. 30 eingreifen, wobei die Führungsflächen 25, 26 bzw. 35, 36 mit den entsprechenden Flächen der Führungsleisten 201 bzw. 301 zusammenwirken.In the exemplary embodiments shown in FIGS. 10, 11 and 11, 12, the devices 2 and 3 are each provided with guide strips 201 and 301, which engage in longitudinal grooves 27 and 37 of the protective sleeves 20 and 30, the guide surfaces 25 , 26 or 35, 36 cooperate with the corresponding surfaces of the guide strips 201 or 301.

In Figur 14 ist in einer weiteren Ausführungsform das Taschengerät 4 an seinen Seitenflächen 405 mit einer seitlichen Nut 406 ausgestattet, die in einem spitzen Winkel a zur Bodenfläche 401 verlauft. Die beidseitigen Nuten 406 sind in einem solchen Abstand von der Fußseite 402 des Taschengeräts 4 angeordnet, daß in sie die Schutzhülle 40 in Pfeilrichtung mit den seitlichen Führungsleisten 44 einschiebbar ist. Wie die Abbildung zeigt, hält die Schutzhülle 40, auf eine Tischplatte aufgelegt, das Taschengerät 4 so in einer Schräglage, daß das Bedienungsfeld 403 und das Anzeigefeld 404 von oben her liecht bedienbar bzw. ablesbar sind.In a further embodiment in FIG. 14, the pocket device 4 is provided on its side surfaces 405 with a lateral groove 406 which extends at an acute angle a to the bottom surface 401. The grooves 406 on both sides are arranged at such a distance from the foot side 402 of the pocket device 4 that the protective cover 40 can be inserted into them in the direction of the arrow with the lateral guide strips 44. As the illustration shows, the protective cover 40, placed on a table top, holds the pocket device 4 in an inclined position in such a way that the control panel 403 and the display panel 404 can be easily operated or read from above.

Wie die Figuren 15 und 16 zeigen, können die an den Langs-Seitenwänder 52 angeformten Führungsleisten 53 der Schutzhülle 50 mit Anschlägen 56, 57 ausgestattet sein, so daß das Gerät 5 mit einer sich im Abstand von seiner Kopfseite 504 quererstreckenden Nut 505 in Pfeilrichtung D bis zu den Anschlägen 56, 57 einschiebbar ist, wobei das Taschengerät 5 und die Schutzhülle 50 in einem etwa rechten Winkel zueinander fixiert sind. Der Abstand der Nuten 505 von der Kopfseite 504 muß dabei gleich oder kleiner sein als der Abstand der Führungsleisten 53 zur Innenseite der Hüllenrückwand 51. Das Bedienungsfeld 501 bzw. das Anzeigefeld 502 des Taschengeräts 5 läßt sich, wenn das Taschengerät 5 und die Schutzhülle 50 z.B. auf einer Tischplatte abgestützt sind, so besonders leicht bedienen bzw. ablesen.As FIGS. 15 and 16 show, the guide strips 53 of the protective cover 50 formed on the longitudinal side walls 52 can be equipped with stops 56, 57, so that the device 5 has a groove 505 extending transversely from its head side 504 in the direction of arrow D can be inserted up to the stops 56, 57, the pocket device 5 and the protective cover 50 being fixed at an approximately right angle to one another. The distance of the grooves 505 from the head side 504 must be equal to or less than the distance of the guide strips 53 from the inside of the case rear wall 51. The control panel 501 or the display field 502 of the pocket device 5 can be used if the pocket device 5 and the protective cover 50 e.g. are supported on a table top, so it is particularly easy to use and read.

In Figur 17 ist gezeigt, daß die Schutzhülle 60 auch mit einer Stützlasche 62 versehen sein kann, die am Ende des Rückenteils 61 der Schutzhülle 60 angelenkt ist und in Pfeilrichtung E als Stütze abklappbar ist.In Figure 17 it is shown that the protective cover 60 can also be provided with a support tab 62 can, which is articulated at the end of the back part 61 of the protective cover 60 and can be folded down in the direction of the arrow E as a support.

In Fig. 18 ist in einem Ausschnitt eine weitere Ausführungsform einer Schutzhülle 70 bzw. eines Taschengeräts 7 dargestellt, bei der die an den Längs-Seitenwänden 72 angeformten Führungsleisten 73, 74 die Seitenwände 701 des Taschengeräts 7 vollständig übergreifen, so daß sich das Anbringen einer besonderen Nut oder von Führungsleisten an den Seitenwänden des Taschengeräts 7 erübrigt.In Fig. 18, a further embodiment of a protective cover 70 or a pocket device 7 is shown in a detail, in which the guide strips 73, 74 formed on the longitudinal side walls 72 completely overlap the side walls 701 of the pocket device 7, so that the attachment of a special groove or of guide rails on the side walls of the pocket device 7 unnecessary.
