Definitions

  • the invention relates to an electrical outlet system comprising an elongated housing extending along a centre axis, a plurality of electrical outlet plug sockets; and means for connecting said system to a mains supply.
  • Power strips are used extensively in the modern household particularly to provide a mains supply to computer systems with peripheral components and AV-devices clustered in a home entertainment center.
  • Power strips are available in number of sizes depending on the desirable number of sockets. From the users point of view as many sockets as possible should be available. However, this presents the drawback that power strips grows in size and it become increasingly difficult to place out of sight.
  • the need for additional sockets particularly arises when devices, such as chargers for portable electronic equipment, are provided with external AC/DC-adapters integrated with their plug. These have a tendency to interfere with the adjacent socket(s) rendering these unusable.
  • a similar problem may occur when the cord going to the plug is perpendicular to the pins of the plug, as this configuration also has a tendency to interfere with neighboring sockets.
  • US 5,232,381 discloses a double-sided power strip wherein the two sides share a common set of electrode bars. This principle is elaborated in US 5,971 ,808 wherein all sockets are rotated 90° and on one side the spacing between sockets has been increased to accommodate odd sized AC/DC adapters. However, this also means that the design does not utilize the length to provide more sockets.
  • plugs in particular AC/DC adapter plugs
  • the invention provides an electrical outlet system comprising an elongated housing extending along a centre axis, a plurality of electrical outlet sockets; and means for connecting said system to a mains supply, characterised in that said plurality of electrical outlet sockets each are provided with a permanently angular displacement relative to the center axis of the housing provided at two or more different angular displacements.
  • the angle of the angular displacement referred to above is defined as the complement angle to the angle measured from a line intersecting the two current carrying pin receptacles (i.e. commonly neutral and live) of the socket, referred to as the socket line, and the center line (see Figure 3).
  • said power strip housing comprises sockets located on multiple sides, such as on two sides.
  • the power strip comprises sockets located on two sides, i.e. the power strip is double sided. Furthermore, it is preferred that the said two sides are opposite facilitating easy design of a common set of electrode bars. However, sockets may be placed on more than two sides, such a three side, such as four sides, such as five sides, such as six sides.
  • sockets of the invention as discussed above are fixed, to provide simplified production, a preferred embodiment of the invention comprise one or more rotatable sockets for added flexibility.
  • sharing of the electrode bars between sockets on two opposite sides is implemented by placing socket so that one or more sockets on two opposite sides are shifted half a module along the center axis of the power strip.
  • sockets on opposite sides may be placed so that the socket lines of these two sockets intersect. Accordingly, it is preferable to position one or more sockets with an angle less than 0° opposite a socket with an angle more than 0°. Preferably, these two socket share a common center. It is understood that the angle of the permanent angular displacement ( ⁇ ) is to be measured from the same side although reference is made to sockets from opposite sides.
  • a preferred alternate positioning of opposite sockets is placing one or more sockets with an angle less than 0° next to a socket with an angle of less than 0° on the opposite side. This allows the pin receptacles of the sockets to be placed relatively close.
  • one or more sockets with angle ( ⁇ i) of less than 0° is next to a socket with an angle ( ⁇ 2 ) of more than 0° on the opposite side.
  • This configuration was applied for sockets 3 to 6 in Figures 1 and 2.
  • a socket with an angle ⁇ >45° is next to a socket with an angle ⁇ 45° accessible from the opposite side.
  • Placement of sockets with 0° and/or 90° at the ends of the power strip is preferable since is may allow elongated AC/DC adapters to extend either across or along the center axis; which ever is preferable to the user.
  • the sockets of the power strip are supplied with electrical power by two electrode bars.
  • at least one additional electrode bar is used to at supply at least one additional socket.
  • said additional socket(s) is "all ways on” meaning that power is supplied to these sockets as long as the strip is connected to the mains feed.
  • said additional socket(s) is switchable independently of the remaining sockets.
  • the power strip of the preferred embodiment preferably comprises at least one base and said base is preferably mounted on the end of the power strip.
  • Said base preferably further comprises means for managing one or more cord(s) connecting the device(s) and/or the cord connecting the power strip to mains power.
  • the base preferably has two layers and a slit for allowing the cord access the power strip and the center between the two layers holding these layers together may serve as an anchoring point for the cord coming in horizontally. In this way, the cord(s) is only visible entering the power strip at the base, as the distribution to the socket, the sockets and plugs including any AC/DC adapters as well as any excess cord may be hidden by the preferred at least one cover.
  • Preferably two covers are applied for easy access to the sockets.
  • the outlet system further comprises a top.

Abstract

La présente invention concerne un système de prise électrique comprenant un boîtier allongé s'étendant le long d'un axe central, une pluralité de fiches de prise électrique, et des moyens de connexion dudit système à une alimentation de secteur, les multiples fiches de prise électrique étant chacune conçue avec un déplacement angulaire permanent par rapport à l'axe central du boîtier, au niveau d'au moins deux déplacements angulaires différents. Le fait que les fiches aient un déplacement angulaire permanent permet de pouvoir connecter ces dernières par l'intermédiaire de barres d'électrode fabriquées, de préférence, en une seule pièce. Le système de prise électrique conformément à l'invention nécessite par conséquent un assemblage minimal conduisant à une production simplifiée et à une réduction du coût.
