Description

Die Erfindung betrifft eine Schutzhülle für elektrisch betriebene Geräte mit einem auf einer Seitenfläche des Geräts angeordnetem Anzeigefeld und/oder Bedienungsfeld, insbesondere für Taschenrechner.The invention relates to a protective cover for electrically operated devices with a display panel and / or control panel arranged on a side surface of the device, in particular for pocket calculators.

Es sind Schutzhüllen für Geräte der in Frage stehenden Art bekannt, die das Gerät auf fünf Seitenflächen vollständig umhüllen. Derartige Schutzhüllen sind also einseitig offen und werden als Stecketuis bezeichnet. Zur Benutzung des Geräts ist es notwendig, dieses aus dem Stecketui vollständig herauszuziehen und dann das leere Stecketui gesondert aufzubewahren bzw. vom Gerät getrennt abzulegen.Protective covers for devices of the type in question are known which completely encase the device on five side surfaces. Such protective covers are therefore open on one side and are called plug cases. To use the 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.

So ist beispielsweise eine Schutzhaube für elektrische Rasierapparate bekannt (DAS 20 19 851), 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 mnß. 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.For example, a protective hood for electric shavers is known (DAS 20 19 851), which consists of two identical half-shells, which cover the device and are obtained by longitudinal division of the protective hood, and are 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.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schutzhülle für elektrisch betriebene Geräte, insbesondere für Taschenrechner, zu schaffen, welche in mögliehst wenigen Arbeitsgängen und damit preiswert herstellbar ist, die ein sehr geringes Gewicht aufweist, und die vom Gerät selbst während der Benutzung des Geräts nicht getrennt aufbewahrt zu werden braucht. Schließlich soll die Handhabung von Schutzhülle und Gerät völlig unkompliziert sein.The present invention has for its object to provide a protective cover for electrically operated devices, in particular for pocket calculators, which can be produced in as few steps and therefore inexpensively as possible, which has a very low weight, and which is used by the device itself while the device is being used Not needs to be kept separate. After all, handling the protective cover and device should be completely uncomplicated.

Erfindungsgemäß wird dies dadurch erreicht, daß die der äußeren Form des Geräts angepaßte Schutzhülle zumindest vier Außenflächen des Geräts einhüllt, wobei zwei kongruente Seitenteile der Schutzhülle, die in einander parallelen Ebenen angeordnet sind, einander parallele Führungsleisten oder Führungsnuten aufweisen, die mit entsprechenden Führungsflächen am Gerät zusammenwirken.According to the invention, this is achieved in that the protective cover adapted to the outer shape of the device envelops at least four outer surfaces of the device, two congruent side parts of the protective cover, which are arranged in mutually parallel planes, having mutually parallel guide strips or guide grooves, which have corresponding guide surfaces on the device work together.

Mit Vorteil ist die zwei Längsseitenteile, ein Bodenteil und ein Rückenteil aufweisende Schutzhülle einstückig und aus einem flexiblen Werkstoff, beispielsweise einer Kunststoffolie, ausgebildet.The protective cover which has two longitudinal side parts, a base part and a back part, is advantageously formed in one piece and made of a flexible material, for example a plastic film.

Die einander parallelen Führungsleisten oder Führungsnuten sind bevorzugt an den inneren Seitenwänden kongruenter, in parallelen Ebenen angeordneter Seitenteile der Schutzhülle vorgesehen und wirken mit Flächen zusammen, die an zwei einander parallelen Seitenflächen des Geräts angeordnet sind.The mutually parallel guide strips or guide grooves are preferably provided on the inner side walls of congruent side parts of the protective cover arranged in parallel planes and interact with surfaces which are arranged on two mutually parallel side surfaces of the device.

In einer bevorzugten Ausführungsform ist auch die Innenseite des Bodenteils der Schutzhülle mit Leisten oder Nuten ausgestattet, die mit korrespondierenden Führungselementen am Gerät zusammenwirken.In a preferred embodiment, the inside of the bottom part of the protective cover is also provided with strips or grooves which interact with corresponding guide elements on the device.

Die Schutzhülle weist in einer vereinfachten Ausführungsform die Form eines Schubers oder eines Stecketuis auf, wobei zumindest ein Teil, beispielsweise das Rückenteil, mit einer fensterartigen Ausnehmung ausgestattet ist, die die Bedienung des Geräts gestattet.In a simplified embodiment, the protective cover has the shape of a slide or a plug case, at least one part, for example the back part, being equipped with a window-like recess which allows the device to be operated.

Die Erfindung läßt die verschiedensten Ausführungsnöglichkeiten zu. Einige davon sind in den Figuren der Zeichnungen schematisch wiedergegeben, und zwar zeigen:

  • Figuren 1 bis 6 ein Gerät und eine Schutzhülle, deren Seitenteile Führungsleisten aufweisen, die mit entsprechenden Führungsflächen am Gerät zusammenwirken, von verschiedenen Seiten gesehen.
  • Figur 7 eine Teildarstellung eines Geräts mit Schutzhülle in der Seitenansicht.
  • Figuren 8 und 9 Teilschnitte nach den Linien VIII bis VIII durch die Schutzhülle gemäß Figur 7, bei der Führungsleisten an den Seitenteilen der Schutzhülle angeordnet sind, die mit Nuten in den Seitenflächen des Geräts zusammenwirken.
  • Figuren 10 bis 13 zeigen Schutzhüllen, deren Seitenteile mit Nuten versehen sind, in die Führungsleisten eingreifen, die am Gerät angeordnet sind.
  • Figuren 14 und 15 zeigen einen Taschenrechner mit Schutzhülle, wobei die Seitenflächen des Taschenrechners Nuten ausweisen, die nicht parallel zu den Kanten des Taschenrechners angeordnet sind.
  • Figur 18 zeigt den Schnitt durch eine Hülle, die mit einer umlaufenden Kante das Gerät umgreift, so daß zusätzlich Führungsmittel am Gerät nicht erforderlich sind.
  • Figur 16 zeigt die Draufsicht nach VXI auf die Schutzhülle gemäß Figur 15.
The invention allows for a wide variety of design options. Some of these are shown schematically in the figures of the drawings, which show:
  • Figures 1 to 6 a device and a protective cover, the side parts of which have guide strips which interact with corresponding guide surfaces on the device, seen from different sides.
  • Figure 7 is a partial view of a device with protective cover in side view.
  • Figures 8 and 9 partial sections along the lines VIII to VIII through the protective cover according to Figure 7, in which guide strips are arranged on the side parts of the protective cover, which cooperate with grooves in the side surfaces of the device.
  • Figures 10 to 13 show protective sleeves, the side parts of which are provided with grooves which engage in the guide strips which are arranged on the device.
  • FIGS. 14 and 15 show a calculator with a protective cover, the side surfaces of the calculator having grooves which are not arranged parallel to the edges of the calculator.
  • Figure 18 shows the section through a sleeve which surrounds the device with a peripheral edge, so that additional guide means on the device are not required.
  • FIG. 16 shows the top view according to VXI on the protective cover according to FIG. 15.

Die Schutzhülle 11 weist in etwa die Form eines Parallelflachs auf und besteht aus einem Rückenteil 1, den beiden Längsseitenteilen 2, 3, einem Fußteil 4 und der umlaufenden Leiste 5, die sich von den Längsseitenteilen 2, 3 und dem Fußteil 4 aus in einer Ebene-parallel zum Rückenteil 1 um ein geringes Maß nach innen zu erstreckt. Rückenteil 1, die Längsseitenteile 2, 3, das Fußteil 4 und die umlaufende Kante 5 sind aus einem steif/elastischem Werkstoff, beispielsweise einem Kunststoff, einteilig ausgebildet.The protective cover 11 has approximately the shape of a parallel flat and consists of a back part 1, the two long side parts 2, 3, a foot part 4 and the circumferential strip 5, which are in one plane from the long side parts 2, 3 and the foot part 4 parallel to the back part 1 to a small extent to the inside. Back part 1, the long side parts 2, 3, the foot part 4 and the peripheral edge 5 are made in one piece from a rigid / elastic material, for example a plastic.

Wie die Figuren 1 bis 3 zeigen, läßt sich die Schutzhülle 11 vom Gerät 7, 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 (wozu die Schutzfülle vorher um ihre Längsachse um 180° gedreht wird) aufschieben. Bei in dieser Weise aufgeschobener Schutzhülle bleibt (wie Figur 4 zeigt) das Tastenfeld 6 des Geräts 7 weitgehend frei, so daß die Tasten auf dem Tastenfeld 6 ohne weiteres bedienbar sind. In dieser (in Figur 4 dargestellten) Position greift lediglich die umlaufende Leiste 5 über eine Führungskante 10 am Gerät 7 und verhindert so, daß die Schutzhülle in Pfeilrichtung C vom Gerät 7 abrutscht. Voraussetzung für eine gute Verbindung zwischen Schutzhülle und Gerät 7 ist, daß die lichte Weite a bzw. die lichte Höhe b der Schutzhülle den Außenmaßen, d. h. der Breite und der Dicke des Geräts 7, entsprechen.As FIGS. 1 to 3 show, the protective cover 11 can be removed from the device 7, in the illustrated case a pocket calculator, in the direction of the arrow A, d, h. Pull it off in its longitudinal direction and then push it back onto the device in the opposite direction in the direction of arrow B (FIG. 3) (for which purpose the protective filling is first rotated by 180 ° about its longitudinal axis). When the protective cover is pushed on in this way (as shown in FIG. 4), the keypad 6 of the device 7 remains largely free, so that the keys on the keypad 6 can be operated without further ado. In this position (shown in FIG. 4), only the circumferential bar 5 engages over a guide edge 10 on the device 7 and thus prevents the protective cover from slipping off the device 7 in the direction of arrow C. A prerequisite for a good connection between the protective cover and the device 7 is that the clear width a or the clear height b of the protective cover has the external dimensions, ie. H. the width and thickness of the device 7, correspond.

Ein besonderer Vorteil der beschriebenen Schutzhülle besteht darin, daß diese'einerseits (wie in Figur 1 dargestellt) das Tastenfeld 6 und das empfindliche Anzeigefeld 8 vor Stößen, vor Verkratzen und vor Verschmutzung bewahrt, daß jedoch andererseits die Schutzhülle so mit dem Gerät 7 verbunden werden kann (Figuren 3 und 4), daß die Schutzhülle die ungehinderte Bedienung des Geräts 7 erlaubt, gleichzeitig aber am Gerät arretiert bleibt, so daß die das Gerät benutzende Person keinen besonderen Aufbewahrungsort für die Schutzhülle während einer Rechen- oder Meßoperation benötigt.A particular advantage of the protective cover described is that it protects the keypad 6 and the sensitive display field 8 from bumps, scratches and contamination (as shown in FIG. 1), but that the protective cover is connected to the device 7 on the other hand can (Figures 3 and 4) that the protective cover allows the unhindered operation of the device 7, but at the same time remains locked on the device, so that the person using the device does not need a special storage location for the protective cover during a computing or measuring operation.

In einer anderen, nicht näher dargestellten Ausführungsform der Schutzhülle ist die Schutzhülle 26 so ausgebildet und bemessen, daß ihre Seitenwandungen 25 bzw. die umlaufende Leiste 28 die Seitenwände 22 des Geräts 27 vollständig übergreifen (wie dies Figur 18 zeigt), so daß sich eine besondere Nut an den Seitenwänden des Geräts 27 erübrigt.In another, not shown embodiment of the protective cover, the protective cover 26 is designed and dimensioned such that its side walls 25 or the circumferential strip 28 completely overlap the side walls 22 of the device 27 (as shown in FIG. 18), so that a special one Groove on the side walls of the device 27 is unnecessary.

Anstelle einer Führungskante 10 am Gerät (wie dies die Ausführung gemäß Figur 2 zeigt), die mit der umlaufenden Leiste 5 korrespondiert, sind bei den Ausführungsformen gemäß den Figuren 7 bis 13 die Seitenwände der Geräte 37, 47, 57 mit Nuten 38 oder Leisten 48 ausgestattet, die in korrespondierende Rippen 39 oder Nuten 49, 59 in den Schutzhüllen 40 bzw. 50 oder 60 eingreifen.Instead of a leading edge 10 on the device (as shown in the embodiment according to FIG. 2), which corresponds to the surrounding bar 5, in the embodiments according to FIGS. 7 to 13 the side walls of the devices 37, 47, 57 are provided with grooves 38 or bars 48 equipped, which engage in corresponding ribs 39 or grooves 49, 59 in the protective sleeves 40 or 50 or 60.

Wie Figuren 15 und 16 zeigen, kann die umlaufende Kante 69 der Schutzhülle 70 mit einer Stufe 71 ausgestattet sein, so daß das Gerät 77 mit seiner sich quererstreckenden Nut 78 in Pfeilrichtung D bis zur Stufe 71 einschiebbar ist, wobei das Gerät 77 und die Schutzhülle 70 in einem etwa rechten Winkel zueinander fixiert sind. Das Tastenfeld 79 des Geräts 77 läßt sich, wenn Gerät 77 und Schutzhülle 70 auf der Tischplatte 100 abgestützt sind, so besonders leicht ablesen.As FIGS. 15 and 16 show, the peripheral edge 69 of the protective cover 70 can be equipped with a step 71, so that the device 77 with its transverse groove 78 can be inserted in the direction of arrow D up to step 71, the device 77 and the protective cover 70 are fixed at an approximately right angle to each other. The keypad 79 of the device 77 can be read particularly easily when the device 77 and the protective cover 70 are supported on the table top 100.

Die Schutzhülle 87 (Figur 17) kann auch mit einer Lasche 89 versehen sein, die am Ende des Rückenteils 101 der Schutzhülle 87 angelenkt ist und in Pfeilrichtung E als-Stütze abklappbar ist.The protective cover 87 (FIG. 17) can also be provided with a tab 89 which is articulated at the end of the back part 101 of the protective cover 87 and can be folded down in the direction of the arrow E as a support.

Anstelle einer quer zum Gerät 77 verlaufenden Nut 78, in die die Schutzhülle 70 einschiebbar ist, ist in einer weiteren Ausführungsform (gemäß Figur 14) das Gerät 90 mit einer seitlichen Nut 98 ausgestattet, die in einem spitzen Winkel zur Rückwand 97 verläuft. In diese Nut 98 am Gerät 90 ist die Schutzhülle 99 in Pfeilrichtung G mit ihrer umlaufenden Kante 96 einschiebbar. Wie die Abbildung zeigt, hält die Schutzhülle 99, auf die Tischplatte 100 aufgelegt, das Gerät 90 so, daß das Tastenfeld 95 von oben her leicht bedienbar ist.Instead of a groove 78 running transversely to the device 77, into which the protective cover 70 can be inserted, in a further embodiment (according to FIG. 14) the device 90 is equipped with a lateral groove 98 which runs at an acute angle to the rear wall 97. The protective sheath 99 with its peripheral edge 96 can be inserted into this groove 98 on the device 90 in the direction of arrow G. As the illustration shows, the protective cover 99 holds onto the table plate 100 placed, the device 90 so that the keypad 95 is easy to operate from above.
