Definitions

  • This invention relates generally to protective covering devices for use in connection with arrays of key-operated switches. Arrays of this type are ex ⁇ emplified by the push-buttons on a conventional push ⁇ button type telephone set.
  • this telephone set which is usually con ⁇ veniently placed with respect to a work station, is subject to damage from environmental hazards, includ ⁇ ing especially to spillage of liquids, which can readily seep through the openings surrounding the individual push-button keys and cause damage,, in some cases irreparable damage, to the underlying switching mechanisms.
  • many telephone sets include one or more rows of further push-buttons beneath the dialing array, which buttons are used for signaling,
  • I provide a protective cover for a telephone set with an array of key-actuated switches, which generally comprises a flexible elastomeric sheet, having one or more pockets therein, which are adapted to receive and overlie the push-buttons in the array of push-buttons on the tele ⁇ phone set.
  • each of the push-buttons in the array fit into pockets of the cover, so that when the cover is emplaced over the set, all of the push-buttons are covered and the buttons may be operated by depressing the outwardly projecting pockets.
  • the pocket, or pockets may be provided with suitable indicia corresponding to those on the keys, enabling indentification of the keys with the cover placed thereover.
  • the protective cover is further provided with a skirt or border portion, which extends beyond the push—button covering pockets and the sheet is continuous between the lateral edges of same.
  • the gasket is adapted to extend completely around the periphery of the sheet in overlying relation to the border portion.
  • the gasket is flexible and ad ⁇ herent to the border portion of the sheet and to the planar surface of the equipment.
  • the gasket prior to use may have covers on its opposite sides which are removable for attachment of the gasket by the applica ⁇ tion of pressure to the sheet and to the planar surface of the equipment.
