Description
REVOLVABLE PLUG AND SOCKET
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to the support of light electric appliances such as light fittings and small fans.
More particularly, the invention provides a plug and socket combination powering and supporting an appliance in a manner allowing the user to change its orientation. The combination is particularly useful where there is a frequent need to move light appliances from one location to another.
In a previous disclosure, Israel Patent no. 126246, the present inventors described a socket and plug combination for conducting electric power and for mechanically supporting a light-weight appliance by means of said plug. Such appliance can be a light, camera, small TV receiver, TV
camera, a small fan or the like.
In our earlier patent the socket has prong-receiving receptacles similar to those found on conventional sockets. Consequently, after the appliance was plugged into the socket, which itself was rigidly attached to a wall or ceiling, the orientation of the appliance attached to the plug could no longer be changed. Where the item being installed is substantially symmetrical, for example a common incandescent filament lamp mounted in a cylindrical lamp socket, such restriction is meaningless. There are however many lighting fixtures with reflectors which need to be oriented in a certain direction, or may be expected to serve a user in two proximate but different locations. With regard to a non-oscillating fan, or a small television camera or receiver, directional orientation is most important for effective use thereof.
In US Patent no. 4,753,600 Williams discloses an electrical connector for io use with hand tools joined to drop cords. The connector is placed in the cord and allows unlimited rotation without twisting the cable. The connector is not attachable to a building surface and can not support any load.
The rotatable electric connector proposed by Salzberg in US Patent no.
6,068,490 is arranged to be plugged into a wall socket but not to support any load therefrom apart for its own weight. A revolvable portion carries a cable terminated by an electric socket.
OBJECTS OF THE INVENTION
It is therefore one of the objects of the present invention to obviate the limitations of prior art electrical plugs and sockets and to provide an assembly which is configured to both support and power a revolvable load, i.e. an electric appliance.
It is a further object of the present invention to reduce cost by providing an embodiment for single phase supply line requiring only two slip rings in place of the three slip rings in prior-art revolvable plugs.

6 PCT/1L01/01078 DETAILED DESCRIPTION OF THE PRESENT INVENTION
There is seen in FIGS. 1, 2 and 4 a combination of a fixable socket 10 and a plug 12. The plug 12 is revolvable in the socket 10, and receives electric power therefrom. The combination 10 + 12 serves also for mechanically supporting in a io desired orientation a light appliance 14, in the present example a miniature television receiver, receiving said power.
The socket 10 is shown in the present figure attached to a wall 16, seen in FIG. 2. The socket 10 has a flat base 18 and apertures 20 to allow the passage of screws 22. The socket 10 has a non-conductive body made of a plastic. Three spaced-apart hollow arcuate conducting receptacles 24, 26, 28, seen most clearly in FIG. 4, are insulated from each other and have a common center of curvature 36. All three receptacles 24, 26, 28 comprise molded recesses containing conductive inserts 30, one of which is seen in FIG. 2, which can be permanently connected by wires 32 to an electric power supply.
The socket 10 rigidly supports a first structural element 34, comprising a cylindrical aperture, of a mechanical connection located at the center of the radius of curvature 36 of the conducting receptacles 24, 26, 28.
A plug 12 also made of a plastic is configured to match the socket 10. The plug body is made of a plastic, and is somewhat larger than conventional plugs to enable the plug to rigidly support an appliance from a first face 38. The plug 10 has a second face 40 for mechanically supporting the conductive prong rings 43 a,b,c.
The appliance 14 weight is about 0.5 to 5 kg, depending on the support configuration in the case of wall attachment. The shorter the distance between the wall 16 and the appliance center of gravity 42, the higher the load which can be supported.
Three projecting conducting prong rings insulated from each other are positioned to be engagable with the three arcuate receptacles 24, 26, 28 of the socket 10, respectively. The prong rings are connected to conductors 62 for feeding electric power to the appliance 14.
The plug 12 also supports a second structural element 44, engagable to the first structural element 34 of the mechanical connection and allowing the plug 12 to revolve at least part of a revolution about the center of curvature 36.
Preferably and as seen in the figure, the first structural element 34 comprises an aperture and the second structural element 44 comprises a post-like male member engagable with the aperture 34. The reverse order, that is where the socket 10 carries the male member, is also feasible.
Releasable latching means 46 retain the plug 12 in the socket 10, by providing a retention force between the socket and the plug to prevent disengagement and to support the appliance. In the present embodiment latching means 46 comprises a split expandable post end 48 with a shoulder 50. An internal shouldered push rod 52 is axially moved to expand the split end 48, enabling the shoulder 50 to abut the aperture of the first structural element 44.
There is seen in FIGS. 1, 2 and 4 a combination of a fixable socket 10 and a plug 12. The plug 12 is revolvable in the socket 10, and receives electric power therefrom. The combination 10 + 12 serves also for mechanically supporting in a io desired orientation a light appliance 14, in the present example a miniature television receiver, receiving said power.
The socket 10 is shown in the present figure attached to a wall 16, seen in FIG. 2. The socket 10 has a flat base 18 and apertures 20 to allow the passage of screws 22. The socket 10 has a non-conductive body made of a plastic. Three spaced-apart hollow arcuate conducting receptacles 24, 26, 28, seen most clearly in FIG. 4, are insulated from each other and have a common center of curvature 36. All three receptacles 24, 26, 28 comprise molded recesses containing conductive inserts 30, one of which is seen in FIG. 2, which can be permanently connected by wires 32 to an electric power supply.
The socket 10 rigidly supports a first structural element 34, comprising a cylindrical aperture, of a mechanical connection located at the center of the radius of curvature 36 of the conducting receptacles 24, 26, 28.
A plug 12 also made of a plastic is configured to match the socket 10. The plug body is made of a plastic, and is somewhat larger than conventional plugs to enable the plug to rigidly support an appliance from a first face 38. The plug 10 has a second face 40 for mechanically supporting the conductive prong rings 43 a,b,c.
The appliance 14 weight is about 0.5 to 5 kg, depending on the support configuration in the case of wall attachment. The shorter the distance between the wall 16 and the appliance center of gravity 42, the higher the load which can be supported.
Three projecting conducting prong rings insulated from each other are positioned to be engagable with the three arcuate receptacles 24, 26, 28 of the socket 10, respectively. The prong rings are connected to conductors 62 for feeding electric power to the appliance 14.
The plug 12 also supports a second structural element 44, engagable to the first structural element 34 of the mechanical connection and allowing the plug 12 to revolve at least part of a revolution about the center of curvature 36.
Preferably and as seen in the figure, the first structural element 34 comprises an aperture and the second structural element 44 comprises a post-like male member engagable with the aperture 34. The reverse order, that is where the socket 10 carries the male member, is also feasible.
Releasable latching means 46 retain the plug 12 in the socket 10, by providing a retention force between the socket and the plug to prevent disengagement and to support the appliance. In the present embodiment latching means 46 comprises a split expandable post end 48 with a shoulder 50. An internal shouldered push rod 52 is axially moved to expand the split end 48, enabling the shoulder 50 to abut the aperture of the first structural element 44.
7 s Latching means 48 are sized to engage the first structural element 44 with sufficient retention force to support a two kg appliance 14 in a ceiling socket during an earthquake of a severity not causing structural damage to the building in which the combination is installed. Users will not expect an appliance to continue to be supported following a severe earthquake, which damages the building structure io itself.
With reference to the rest of the figures, similar reference numerals have been used to identify similar parts.
FIG. 3 shows an embodiment of an interconnected socket 10 and plug 54.
The socket 10 is seen attached to a ceiling 56. The plug 54 supports a fan 58, 15 which can be directed to face any desired direction by revolving the plug 54 in its socket 10. The bowl-shaped cover 60 is added to improve appearance and to prevent users making contact with electric wires 32, 62. The inner assembly is similar to the plug 12 and socket 10 shown not yet interconnected in FIG. 2.
Referring now to FIG. 5, there is depicted a detail of a socket 64 and plug 20 66 combination wherein both parts 68, 70 of the mechanical connection are conductive and are arranged to be wired for use as an earth connection. It will be appreciated that the earth plug prong ring, 43b in FIG. 2, is eliminated from the plug, an arcuate recess 26 in FIG. 2 is eliminated from the socket, and both plug and socket can be made smaller.
25 The socket 64 rigidly supports a first structural element 68 of a mechanical connection is located at the radius of curvature 36. Element 68 is a female metal

25 The socket 64 rigidly supports a first structural element 68 of a mechanical connection is located at the radius of curvature 36. Element 68 is a female metal
8 component molded into the plastic body 66. Due to the high stress on element 68, a metal construction is in any case an advantage, thus opening the option of utilizing the mechanical connection as an earth connector.
The retention mechanism in the present embodiment comprises a plurality of hard captive balls 72 which are shown in the figure at their outer position. The balls 72 retain the plug 66 in the socket 64, as the post 70 can not be withdrawn through the element 68 while the balls 72 project outwards. Pushing the rod 74 inwards, against the compression spring 76 allows the balls 72 to retract into a recess 78 to allow withdrawal of the plug 66.
FIG. 6 shows a socket 80 and plug 82 combination similar to that seen in FIG. 1. The appliance being powered and supported is an electric light fitting 84.
The hollow support arm 86 carrying cables 88 is attached to the side of the plug 82. The light fitting 84 can be quickly installed, adjusted to radiate in a desired direction, and quickly removed when not needed - without the aid of tools.
The scope of the described invention is intended to include all embodiments coming within the meaning of the following claims. The foregoing examples illustrate useful forms of the invention, but are not to be considered as limiting its scope, as those skilled in the art will readily be aware that additional variants and modifications of the invention can be formulated without departing from the meaning of the following claims.
