Figure 13 is a perspective view of the second embodiment in use.
In the first embodiment, the device 10 comprises connection means 11 spaced from power point means 12 by spacer means 13.
The power point means is in the form of a standard mains electricity power point and includes bores 14 in the rear side of the housing thereof for receiving, for example, screws, for securing the power point means 12 to a wall.
The bores 14 are countersunk.
The power point means 12 includes an aperture 15 in the lower side of its housing through which wires (not shown) from the connection means 11 extend. The wires constitute the aforesaid electrical connection. The wires (not shown) are house within a rectangular sleeve which constitutes the spacer means 13. The lower end of the sleeve 13 is of increased depth with respect to the remainder of the sleeve 13. The front of the sleeve 13 is removable and forms upper and lower covers 16, 17. The lower cover 17 covers the lower part of the sleeve 13 which is of increased depth.The upper cover 16 includes three pairs of projections 18 extending inwardly therefrom. -Each projection 18 includes a screw threaded bore 19 and corresponding apertures 20 are provided in the rear side of the sleeve 13 such that the upper cover 16 can be secured to the remainder of the sleeve 13 by means of screws (not shown). The lower cover 17 also includes a pair of projections 18 including bores 19 arranged to receive screws (not shown) extending through apertures 20 in the rear side of the sleeve 13. The apertures 20 are countersunk. As the screws (not shown) securing the upper and lower covers 16, 17 to the remainder of the sleeve 13 are provided on the rear side of the sleeve 13, the screws are not accessible in use.
The connection means 11 comprises a generally rectangular housing 21 within which are mounted the compqnents of a standard U.K. three pin plug. The pins 22 extend substantially perpendicularly to one side of the housing 21. The connection means is fused for safety. The housing 21 is elongate so as to extend beyond the edge of a standard mains electricity power point in use. The housing 21 defines within its upper side an aperture 23 which is bounded by two outwardly turned jaws 24. The opening at the lower end of the sleeve 13 is wide enough at its outer end to receive the jaws 24 but then is narrowed towards its inner end by inwards projections 25 from either wall.Thus, the jaws 24 of the connection means housing 21 can be inserted into the lower opening of the sleeve 13 at its outer end but sliding between the connection means housing 21 and the sleeve 13 will connect the two parts. The jaws 24 and the projections 25 are arranged to allow sliding perpendicular to the axis of the sleeve 13.
In use, on a standard mains electricity point socket in a house the pins 22 of the connection means 11 are first inserted into the socket 26. The sleeve 13 is then slid with respect to the connection means 11 so as to lie with its rear side adjacent the wall 27. Bores are then created in positions corresponding to the bores 14 in the power point means 12 and the power point means 12 is secured to the wall 27 by means of screws through the bores 14 and extending into the bores in the wall 27.
The power point means cover 28 is then attached to the remainder of the power point means 12 and the socket 26 may then be switched on so that the power point means 12 may be used.
Thus as shown in Figure 4, the device 10 may be used to enable a person to plug in an appliance at a higher level than the socket provided.
In the second embodiment, the same reference numerals will be used to describe the equivalent features.
The power point means 12 is in the form of a standard mains electricity power point having two sockets for standard three-pin plugs. Three downwardly extending pins 30 are provided in a recess in the lower face of the power point means 12. The pins 30 do not extend out of the recess 31.
The spacer means 13 of the embodiment comprises three lengths of rod 32 joined by two connectors 33, 34. Each rod 32 is solid and made from e.g. plastics material, and includes embedded therein three hollow tubes 38 of
conductive material running through it in positions corresponding to the pins 30. The tubes 38 may be made from e.g. copper. The rod 32 is uniform so that it may be cut transverselly anywhere along its length to expose the same cross-section. The connectors 33, 34 each include two recesses 36 and three pins 35 extend outwardly in each recess 36. The connector 34 is straight and the recesses 36 are oppositely disposed.
The connector 33 is turned through a right angle so that its recesses 36 are disposed perpendicularly to one another. The recesses 36 of the connectors 33, 34 and the recess 31 of the power point means 12 are dimensioned to receive an end of one of the rods 32 and the pins 30, 35 are disposed so as to engage in the sockets 37 provided by the ends of the conductive tubes 38.
The connection means 11 comprises a generally rectangular housing 39 within which is mounted the components of a standard UK three-pin plug. The pins 40 extend substantially perpendicularly to one side of the housing 39. As before, the connection means is fused for safety.
The housing 39 is elongate but in this embodiment is elongate downwardly so as to extend beyond the edge of a standard mains electricity power point in use. Outwardly turned jaws 24 are provided on the lower face of the housing 39 and are received in an opening in an adaptor 41 which corresponds to the opening at the lower end of the sleeve 13 in the first embodiment so that the adaptor is slidably mounted with respect to the housing 39. The adaptor 41 includes two oppositely disposed recesses 42 extending transversely with respect to the cqnnection means 11. Three pins 43 are mounted within each recess 42 and extend outwardly. Again, the recesses 42 are dimensioned to receive an end of a rod 32 and the pins 43 are disposed to engage with the sockets 38 defined by the tubes 37 of a rod 32.
Caps 44 are provided to cover the pins 30, 35, 43 prior to use.
In use, the connection means 11 is plugged into a standard UK mains socket and the adaptor 41 is slid with respect to the housing 39 to lie adjacent a wall 27. A short rod 32 is then inserted into one of the recesses 42. The right angle connector 33 is then placed over the other end of the short rod 32 so that its other recess points upwardly. A further rod 32 is then inserted into the upwardly facing recess of the right angle connector 33, the opposite end of the rod 32 being connected to another rod 32 through the straight connector 34. The upper end of the second rod 32 is inserted into the socket 31 of the power point means 12 which is then attached to the wall 27 as described in relation to the first embodiment.
If desired, a further power point means 12 may be connected to the connection means 11 through rods 32 inserted into the other recess 42 of the adaptor 41.
The rods 32 or connectors 33, 34 may be secured to a wall in use in any suitable manner if desired.
The sleeve 13, rods 32, power point means housing and connection means housing may each be made from any suitable material and they may be made from formaldehyde, or high impact plastic.
The power point means 12 need not be securable to a wall as described but may be securable in any suitable manner and need not be securable, if desired.
The connection means 11 and power point 12 need not correspond to a standard U.K. mains electricity plug and socket respectively, as shown, but may take any appropriate form, and may, for example, correspond to a standard U.S.A. mains electricity plug and socket, respectively.
The connection means 11 and the sleeve 13 need not be slidably connected in the manner shown, but may be slidably connected in any suitable manner or may not be slidably connected as desired.
