Description
ical Socket tus
This invention s to electrical socket apparatus.
As is well known, electrical socket boxes are employed to enable electrical
appliances to be connected to mains wiring of a house or other building. Socket
boxes are open-sided to receive terminals located on the rear face of electric
es, and are generally located, in use, in suitably sized openings formed in
a wall or other surface. On many occasions, the terminal-bearing rear face of the
switch is sufficiently large to cover entirely the wall opening leaving no gaps
between the switch and the wall opening. On some occasions, r, the
opening is not entirely covered by the rear face of the switch leaving gaps
n the switch and the perimeter of the opening. This is both dangerous
and unsightly. Such gaps may well be present when fitting a square or
rectangular switch to a round or circular socket box.
Circular section socket boxes have the age of being easier to install than
those of square or rectangular socket boxes and have the additional advantage
of being able to rotate within a wall opening of the same shape for ease of
connection of the individual mains wire to the appropriate terminals of the switch.
However, on many occasions the diameter of a circular section socket box is
larger than the height of the switch thereby leaving gaps between the switch
boundary and the open side of the socket box.
One objective of this invention is to provide a socket box apparatus which does
not suffer from this disadvantage. While this applies to preferred embodiments, it
should be understood that the object of the invention per se is simply to provide
the public with a useful choice. Therefore any objects applicable to preferred
embodiments should not be taken as a limitation on the scope of the monopoly
claimed.
In broad terms in one aspect the invention comprises electrical socket apparatus
comprising an open-sided socket box of rounded or circular cross section for
on within a similarly shaped opening set in a wall or other surface, the
socket box including at its open end an inwardly projecting annular lip formed
with a plurality of fixing elements, an electrical switch socket connectable to the
socket box and ing a rectangular front face including s for receiving
pins of an electric plug of an electrical nce and a rear face from which
protrude terminals for connection to mains wiring to be ed within the socket
box, and a frame-shaped rectangular front plate whose length and height are
greater than the length and height of the front face of the switch socket and which
includes fixing elements complementary to those of the r lip of the socket
box, the front plate, in use of the apparatus, being positioned between the switch
socket and the wall or other surface into which the socket box is mounted with
the boundaries of the open end of the socket box and the wall or other surface
opening in which the socket box is located entirely covered by the front plate, the
tus being characterised in that either:
(a) the fixing elements of the annular lip of the socket box comprise
recesses or openings formed in the lip, and those of the front plate comprise clips
or projections which respectively locate over and behind the recesses, or
protrude into the gs, or
(b) the fixing elements of the annular lip of the socket box comprise
clips or projections and those of the front plate comprise recesses or openings
respectively.
The front plate and switch may be square and the socket box may be circular.
The fixing elements of the annular lip of the socket box may comprise recesses
or openings formed in the lip, and those of the front plate may comprise clips or
projections which
tively locate over and behind' the recesses, or
projections which protrude into the
openings.
Alternatively, the fixing elements of the r lip may
comprise clips or tions and those of the front plate may
comprise recesses or openings.
In another aspect, ‘the invention provides electrical socket
apparatus comprising a frame-shaped rectangular front plate
and a socket box which, in use, is set in an opening formed in
the wall or other e, the front plate including fixing
elements positioned to engage complementary fixing elements
present on or in an inwardly extending lip around the
periphery of the open end of the socket box, the front plate
being dimensioned to cover, in use, the entire periphery of
the open end of the socket box.
The socket box may be circular in
cross section.
The invention will now be described with reference to the
accompanying mmatic drawings in which:—
Figure l is an exploded View in perspective of socket box
apparatus in accordance with the invention;
Figure 2 is a perspective View of the apparatus illustrated in
Figure 1 partially installed in a wall surface;
Figure 3 shows the apparatus when fully installed in a wall
surface;
Figure 4 is a plan view of a backing plate of the illustrated
apparatus;
Figure 5 is a section taken along line C~C of Figure 4; and
Figure 6 is a detailed View of the circled area of Figure 5.
The socket bOX apparatus illustrated in the drawings includes
‘a conventional switch 1 for ting an ical appliance
to the mains circuit of a building. As is conventional, the
switch is square shaped in plan. The rear face of the switch
carries terminals for connection to mains wiring drawn into a
socket box 2 from the ring main of the building. As shown,
the socket box is ar in cross section.
As shown in Figure 2, the socket box 2 is located in a
rly shaped opening 3 formed in a wall surface 4. The
socket box conventionally includes fixing sleeves 5 for
receiving screws 6 of the switch 1. Positioned between the
rear face of the switch 1 and the socket box 2 is a frame»
shaped front plate 7 formed with a central square shaped
opening 8.
As will be seen from Figure 3, the overall length and width of
the front plate 7 are each larger than the length and width of
the switch 1. It will also be seen from Figure 3 that the
front plate dimensions are larger than the maximum dimension
of the opening 3. ,
The width and length of the plate opening 8 are each less
than the width and length of the switch so that, as will again
be seen from Figure 3, the rear face of the switch is bordered
by the plate 7.
The widths of the sides of the front plate 7 are sufficient to
cover entirely the perimeter of the socket box 2 and the wall
opening 3 without impeding access to the interior of the
socket box when fitted.
As will be seen from Figures 1 and 2, the socket box 2 has at
-its open end an r lip 9 formed with four es which
define ledges 10. The ledges 10 define fixings which, as
described below, enable the front plate 7 to be connected to
the socket box 1.
As will be seen more clearly from Figures 4 and 5, the front
plate 7 includes four projections 11 each having a sideways
ing lip 12. The ledges 10 and the lips 12 define fixings
complementary to those of the socket box. That is to say, the
lips can locate below the ledges and within the confines of
the lip 9 to connect the front plate 7 to the socket box 2.
On assembly of the rated apparatus, the socket box 1 is
installed in the wall opening 3. Mains wiring drawn into the
socket box is then connected to the switch terminals with the
front plate positioned between the switch and the socket box.
Once connected, the front plate is positioned over the wall
opening 3 with the fixings of the front plate located inrthe
recesses and behind the ledges 10. The switch is then secured
to the socket box by means of the screws 6.
It will be iated that the ing is exemplary of
apparatus in accordance with the invention and that
modifications can readily be made thereto without departing
from the true scope of the invention as set out in the
appended claims.
