Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
