Definitions

  • 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.
  • 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.
  • a protective hood for electric shavers 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a protective cover 10 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.
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
