Description
2~ 35 Prior Art Conventional electri.cal wall outlets have a box containing an electrical receptacle with two or more sockets, the receptacle being moun-ted by end lugs ln the box, and the socket portions of the receptacle protrude slightly through a face plate which is flush with the wall. With cer-tain new receptacles, the whole rectangular front of the receptacle containing two socket portions for plugs protrudes slightly from the face plate.
This conventional arrangement has several shortcomings:-(1) Wi-th or without plugs inserted into the receptacle, the arrangement is somewhat untidy and detracts from the appearance of a wall; -.
(2) The plugs project horizontally from the receptacles which are flush with the wall surface; to allow enough space for the cable to bend it is usually necessary for furniture to be spaced 3 or 4 i.nches from the wall. Pushing furniture against the plug can damage the receptacle or plug, or cause unsafe bending of the cable; and (3) The conventional arrangement provides little protection for children who can insert metal '' ~ .
z~ s objects into the live terminals of the rece2tacle, and who can freely remove æ]ugs when they are in place. Also, during cleaning operations, water may enter the live terminals of the receptacle.
Summary of the Invention In accordance with the invention, an electrical outlet for receiving at least one wall plug comprises a housing having an open front and being arranged for mounting within a wall cavity such that the front is substantially flush with the wal].. The housing has side walls extending rearward].y of the front and has an upper rear wall extending between the side walls and arranged to accommodate a receptacle for a plug or plugs, this upper .rear wall s].oping downwardly and rearwardly at an angle of between 25 and 50 relative to the plane of the front, the receptacle being held at an angle so that its front is parallel to the upper rear wal].. The arrangemen-t is such tha-t when a plug of typical length, say 4.5 cm or less, is inser-ted into the receptacle it is contained wholly within the housing, and the cord hangs from the cavity close to the wa]l. This avoids the problem of p]ugs projecting from the wall and provides a neat appearance for the cord.
Further in accordance wi-th the invention, one or more doors are provided which norrna]]y substan-tially close the front of the outlet, the doors lying in a plane just in front of the wa]1 surface. This greatly improves the appearance of -the out]et, and the doors can readily be painted or decora-ted to match the appearance of the wall.
The door or doors are provided with notches to allow the cables to pass from the outlet, close to the bottom thereof. The doors are not only aesthetically pleasing, but is readi]y provided with child proof closure means so that a chi]d cannot gain access to the sockets. The provision of doors also restricts entry of water into -the live parts of the outlet during c]eaning.

- Fig. 10 is a side view of the housing of the outlet shown in Fig. 8;
- Fig. 11 is a side view of a fourth form of the outlet; and - Fig. 12 is a front view of -the out]et of Fig. 11 with plugs removed and doors open.
Referring to Figs. 1-5, and particularly Fig. 4, -the electrical outlet is designed to fi-t within a metal outlet box 10, which is of generally conventional form although slightly deeper than the most usual type of outlet box. In the preferred embodiment, the depth of z~
the outlet box is about 3 inches or 76 mm, and is suitable for fitting within a standard wall W formed by 2 x 4 inch studs. Apart from the depth, the one special feature of the box is two receptacle mounting brackets 12 S each of which slopes downwardly and rearwardly at an angle of 45, from a top end which is about 2 cm behind the front face, to a bottom end which is about 1 cm in front of the rear of the box and slightly above the center. The ~wo mounting brackets are both close to the opposite si.de walls of the box and are coplanar. They provide screw holes for mounting the end lugs of a laterally extending receptacle 14, having two spaced sockets each for a three pin plug. The plugs of course will be spaced laterally rather than vertically as in the usual arrangement.
Instead of the usual face plate which fi.ts over a receptacle in conventional outlets, there is provided a~
housing 20 which is moulded of plastic material and which has:-- a peripheral, rectangular flange 22 arranged to fit against the open end of the box 10;
- two rearwardly extendi.ng, paral.lel side walls 24, which fit within the sides of the box lOi - rearwardly extending upper and lower horizontal , , ' , z~
wall portlons 26 and 27;
- an upper rear wall portion 28 which extends rearwardly downwardly from the rear end of wall portion 26, at an angle of 45 to the plane of the fronti and - a lower rear wall portion 29 which extends upwardly and rearwardly from the rear of the wall portion 27.
The wall portions 28 and 29 are connected at the rear of the housing by a narrow, vertical but horizontally extending wall portion 30. This wall portion 30 is provided with two screw hoIes, and allows the housing to be connected by screws 32 to tapped holes in the rear of the box 10. This holds the housing in place in the box.
As seen in Figs 3 and 5, the upper rear wall 28 has a rectangular, laterally extending aperture 34 designed to fit over the front of the receptacle 14 carried by the box. The housing provides an enclosed and insulated space while allowing access to the receptacle 14.
As shown in Figs. 1 and 5, the front flanges of the housing have extens1ons in the front which provide inwardly facing guide grooves for the flanges 40 of a vertically sliding door 42. The lower ends of the guides have stops 43 which act against lower ends of the door flanges to limit downwards movement. As shown in Fig. 1, the door has two s]ots 44 in-tended to accommodate the cables extending from the two 3-pin p]ugs P inserted in-to the receptac]e; the upper ends of the notches are angled as shown in Fig. 4 to minimize the distortion of the cable. At the bottom of the center of the door is a horizontal bore, and the lower flange of the housing has a threaded brass insert 45 which corresponds in portion to this bore when the door is in the c]osed position.
This threaded brass insert is intended to receive a thumb operated screw 46, indicated in Fig. l; this screw is preferab]y of the multi-start type which can be secured with less than a full rotation. This provides a child proof feature preventing easy access to the receptacle, and especially preventing chi]dren from inserting objects into the receptacle.
It will be noted from Fig. 1 that not only does this outlet give a neat appearance, but the manner in which the receptacle is angled has two advantages; firstly it allows the use of a plug somewhat longer than wha-t could be used within the same size of box 10, if used horizontally, and secondly it a]lows the cord to hang down at a small angle to the wa]l so there is very little restriction on placing furniture against the outlet. The outlet is designed so that plugs having a length of 4.5 cm or ]ess, when inserted into the receptac]e, can be contained wholly within the housing. Preferably, -the arrangemen-t is such that the cable passes out of the door a-t an ang:le of ]ess than 30 to the vertica].
In the variations shown in Figs. 6 and 7, the general nature of the outlet is simi]ar so only -the differences will be described.
Firstly, it will be noted that the angle of the upper rear wall 28' of the housing is set at 30 to the vertical, rather than 45 as in the first embodiment.
This different angling means that the outlet cable from a plug will pass out of the out]et close to its vertical center, rather than near to the bottom. Instead of a sliding door, upper and lower pivoted doors 50 and 51 are provided. For this purpose, the front flange of the housing provides pairs of horizontally aligned bores adjacent the top and bottom of the out]et, and the doors have horizontally extending pivot rods the ends of which are located to pivot in these bores. Each door has a pair of semi-circular notches positioned to receive the cables which, as indicated, ex-tend from around -the vertical mid point of the housing. Each door has a projecting lip 52 at its lower end allowing it to be g pulled open. At the vertical center of one side flange is a threaded insert 53 for receiving a child safe screw which also passes through an extension of one of the two doors.
Figs. 8 to 10 show a third embodiment which is similar to -the second embodiment in relation to the geometry of the housing, but which differs from both earlier embodiments in that:-(1) The receptacle, instead of being a conventional type of receptacle held by brackets in the box, is integrally moulded with the housing so as to extend rearward]y from the upper wa]l portion of 28" the housing. Accordingly, assembly of the unit is simpler than with the previously described arrangements; and (2) A pair of horizon-tally sliding doors 55 is provided. The guide means for these doors are provided by extensions 56 of the top and bottom flanges of the housing, these providing guide means in the form of facing grooves which receive projecting flange portions of the doors. Each door has a centrally located, horizontal notch 57 for accommodating the cables, the notches cut being cut at about 30 to accommodate such a 13~
slope of the cable. At the outer edges of each door there are provided child proof screws 58 which engage in threaded inserts 59 in the side f]anges of the housing.
In the fourth em~odimen-t of the invention, as shown in Figs. 11 and 12, again the housing and receptacle is an integrally moulded unit, although in this case two receptacle porti~ns are provided one above the other, the outer face of each receptac]e portion being set at an angle of about 30 to the plane of the fron-t of the outlet. As shown in Fig. 11, in this embodiment there is also provided a power surge reset switch 60, which is a commercially available item. The door arrangement of this embodiment is shown in Fig. 12, as including two side by side doors 61 each pivoted, by internal brackets, to the top and bottom wall portions 26' and 27' of the housing. At the top and bottom of each door is a ]ug 62, having a screw threaded bore, and one of each lug - carries a finger operated screw which can be engaged with the other lug when the two doors are closed, as a child safe feature. Another feature of this embodiment is that the notches 65 of the door, which accommodate the two cables, are provided with resilient linings which close tightly on to the cables leading to the plugs.
This conventional arrangement has several shortcomings:-(1) Wi-th or without plugs inserted into the receptacle, the arrangement is somewhat untidy and detracts from the appearance of a wall; -.
(2) The plugs project horizontally from the receptacles which are flush with the wall surface; to allow enough space for the cable to bend it is usually necessary for furniture to be spaced 3 or 4 i.nches from the wall. Pushing furniture against the plug can damage the receptacle or plug, or cause unsafe bending of the cable; and (3) The conventional arrangement provides little protection for children who can insert metal '' ~ .
z~ s objects into the live terminals of the rece2tacle, and who can freely remove æ]ugs when they are in place. Also, during cleaning operations, water may enter the live terminals of the receptacle.

Referring to Figs. 1-5, and particularly Fig. 4, -the electrical outlet is designed to fi-t within a metal outlet box 10, which is of generally conventional form although slightly deeper than the most usual type of outlet box. In the preferred embodiment, the depth of z~
the outlet box is about 3 inches or 76 mm, and is suitable for fitting within a standard wall W formed by 2 x 4 inch studs. Apart from the depth, the one special feature of the box is two receptacle mounting brackets 12 S each of which slopes downwardly and rearwardly at an angle of 45, from a top end which is about 2 cm behind the front face, to a bottom end which is about 1 cm in front of the rear of the box and slightly above the center. The ~wo mounting brackets are both close to the opposite si.de walls of the box and are coplanar. They provide screw holes for mounting the end lugs of a laterally extending receptacle 14, having two spaced sockets each for a three pin plug. The plugs of course will be spaced laterally rather than vertically as in the usual arrangement.
Instead of the usual face plate which fi.ts over a receptacle in conventional outlets, there is provided a~

- an upper rear wall portion 28 which extends rearwardly downwardly from the rear end of wall portion 26, at an angle of 45 to the plane of the fronti and - a lower rear wall portion 29 which extends upwardly and rearwardly from the rear of the wall portion 27.
The wall portions 28 and 29 are connected at the rear of the housing by a narrow, vertical but horizontally extending wall portion 30. This wall portion 30 is provided with two screw hoIes, and allows the housing to be connected by screws 32 to tapped holes in the rear of the box 10. This holds the housing in place in the box.
As seen in Figs 3 and 5, the upper rear wall 28 has a rectangular, laterally extending aperture 34 designed to fit over the front of the receptacle 14 carried by the box. The housing provides an enclosed and insulated space while allowing access to the receptacle 14.
As shown in Figs. 1 and 5, the front flanges of the housing have extens1ons in the front which provide inwardly facing guide grooves for the flanges 40 of a vertically sliding door 42. The lower ends of the guides have stops 43 which act against lower ends of the door flanges to limit downwards movement.
