Definitions

  • This invention relates to a security guard for an electric plug and socket.
  • a guard adapted to be used with an electrical outlet socket which comprises a first framework adapted to fit behind the faceplate of the socket and be retained thereby, and, hingedly attached thereto, a cover adapted, in use, to swing over and retain a plug in the socket, there being means for securing the cover in the retaining position.
  • the device of the invention comprises a generally square or rectangular framework having inturned peripheral edge portions pieces which enable it to be retained behind the faceplate of a domestic electrical outlet socket.
  • This is simply attained in practice by loosening the screws on the faceplate, inserting the frame and re-tightening the faceplate screws.
  • Pivoted to one side of the frame is the cover which cover in the swung back or open position, allows free access of a plug or plugs to the electrical socket.
  • the cover is swung over to the retaining position where it is held by the securing means.
  • the latter may be a simple catch or may be adapted to receive a padlock or may indeed incorporate a lock mechanism.
  • the device of the invention may be made of any suitable material such as metal or plastics material, but is preferably a plastics covered metal.
  • the device may be made in any suitable colour or combination of colours so as to fit in with a room's decor or form an attractive contrast.
  • Figure 1 is a diagramatic view of a device in accordance with the invention.
  • Figure 2 is a diagramatic view of the device in the retaining position on an electrical socket.
  • the device generally designated 10 comprises, in the example shown which is adapted for use with a twin electrical outlet socket, a generally rectangular framework 12.
  • the framework 12 has inturned edge portions 14 which will be retained behind a faceplate 16 on a double electrical outlet socket generally indicated at 18.
  • the socket 18 has two sets of plug receiving holes (not shown in drawings) and two associated switches 20.
  • Hingedly attached to the frame 12 aL 22 is a cover 24.
  • the cover 24 has a pair of bent- over portions 26 which, in use, each overlie and obscure the top of an electrical plug (not shown in the drawings) .
  • the lower edge 28 of the cover 24 may be bent outwardly so as not to present a sharp edge to the electrical cable or cables leading from the plug or plugs.
  • Securing means 30 in the form of a catch are provided with one member 32 being fixed to the framework 12 and a corresponding slot 34 being formed in the cover 24 .
  • Locking means 36 may also be provided.
  • the faceplate 16 of the socket 18 is removed by loosening retaining screws.
  • the framework is positioned behind the faceplate and the latter re-affixed in position by means of the screws.
  • the framework 12 does not come anywhere near the electrical connections within the socket 18 and may therefore be made of a conducting material although it will usually be preferred for it to be at least coated with a non-conductor such as a plastics material.
  • the cover 24 With the framework 12 secured in place the cover 24 can be pivoted from the position shown in figure 1 (the "open” position) to the position shown in figure 2 (the “retaining” position). In the open position plugs may be freely put into and taken out from either of the receiving areas of the socket 18. If, however, it is desired to retain a plug in position once it has been inserted, then the cover 24 will be swung across to the position shown in figure 2 when the member 32 will co-act with the corresponding slot 34 which are arranged to be a snug fit with one another thereby acting as a catch to secure the device. This will usually be sufficient to prevent a young child from being able to swing back the cover and thereby gain access to the plug.
  • a padlock can be inserted through the members 32 and 34 thereby locking the device against any unauthorised opening or a locking arrangement 36 employed.
  • the latter may be appropriate in, for example, an office environment where it is desired to keep a computer installation running twenty-four hours a day and there is a danger that cleaners or the like will remove the plug from the socket inadvertently or to use cleaning equipment.
  • the cover may be designed, as shown, to allow adult access to the switches 20 to switch on and off the electrical equipment plugged in. However, the restricted access and lack of leverage that this ensures prevents a young child from being able to operate the switches.
  • the guards 26 may be extended so as to cover the switches 20 also.
  • the device of the invention provides a simple and inexpensive means of securing electrical plugs against inadvertent or unauthorised removal.

Abstract

L'invention concerne un boîtier de protection (10) conçu pour être utilisé avec une prise de courant électrique. La protection comprend un premier cadre (12) s'adaptant derrière la face de la prise et servant à retenir ce dernier. Un cache (24) est fixé pivotant au cadre (12); il sert, lorsqu'on l'utilise, à se rabattre sur une fiche située dans la prise (18) et à la protéger. Un système de fixation (30) se présentant sous forme de cliquet est prévu, dont un des éléments est fixé au cadre (12) et une fente associée (34) est formée dans le cache (24). Le boîtier de protection de cette invention permet d'éviter le retrait accidentel ou non autorisé de la fiche électrique de la prise dans laquelle elle se trouve.
