Description
J
LIGHT BULB FITTING
This invention relates to an electrical light bulb fitting for use particularly, but not exclusively, with light bulbs with a bayonet fitting.
Light bulbs are connected to an electrical fitting for use with either a screw thread, or a spring loaded bayonet fitting. Both types of fitting are easy to use when they are readily accessible, for example on a table lamp.
However, some light bulb fittings are difficult to access, for example those on a ceiling or wall. Often a step ladder is required, and it is sometimes necessary to remove or fit a light bulb with one's arms outstretched above one's head. This may be awkward and can be dangerous.
The present Invention is intended to overcome some of the above problems.
Therefore, according to the present invention a light bulb fitting comprises a base connected In use to an electricity supply, light bulb attachment means and electricity conducting means, in which in use the light bulb attachment means serves to attach a light bulb to the base by means of a magnet, and in which when a ilght bulb is attached to the base in use, the electricity conducting means conducts electricity from said electricity supply to said light bulb.
The light bulb attachment means can comprise a magnet, adapted to attach to a piece of magnetic metal provided on a light bulb with which the fitting is used.
Alternatively the light bulb attachment means can comprise a piece of magnetic metal, adapted to attach to a magnet provided on a light bulb with which the fitting is used.
However, as known light bulbs do not commonly carry either a magnet or any magnetic metal, it will be appreciated that a new light bulb would need to be created to co-operate with the light bulb fitting as described in the Statement of Invention.
Therefore In a preferred construction the light bulb attachment means can comprise a connector, and said connector can have secondary light bulb attachment means at a first end, and said connector can be attached to the base by means of a magnet. The electricity conducting means can extend from the base, through the connector to said bulb, and can supply electricity from said electricity supply to said light bulb.
It will be appreciated that the secondary light bulb attachment means can be any known type of light bulb attachment means, but in a preferred construction it can comprise a spring-loaded bayonet fitting.
Preferably the base can comprise a known type of mains electricity connection means, a cover portion to cover the mains electricity connection means, a pair of base contact terminals, a socket and either a magnet, or a piece of magnetic metal at the base of the socket.
The connector can be provided with either a magnet or a piece of magnetic metal at a second end, which ever is required to co-operate with the base. In a preferred construction the connector is provided with a magnet, and the base is provided with a piece of magnetic metal.
The connector can be provided with a pair of conducting rods, which each have a first contact terminal at a first end, and a second contact terminal at a second end. In use the first contact terminals can contact the base contact terminals, and the second contact terminals can contact the light bulb. Therefore, the electricity conduchng means can comprise the base contact terminals and the conducting rods. l
The conductng rods can be spring loaded as part of the spring-loaded bayonet fitting mechanism. In a preferred construction each conducting rod can be provided with a flange at a mid point along its length, and a coil spring can be mounted In compression against the flange.
Each rod and coil spring can be disposed inside an annular passage running through the connector. Each annular passage can be provided with a stop ring at one end, which prevents the flange passing, and the rods being pushed out by the coil springs.
The rods and coil springs are adapted such that when a light bulb is connected to the bayonet fitting in use, and the conducting rods are held in compression against the light bulb, the first contact terminals are substantially level with the second end of the connector, such that when the connector is connected to the base, the first contact terminals are in electrical contact with the base contact terminals.
The socket can be annular in shape, and can surround the base contact terminals. The piece of magnetic metal can also be annular, and can be disposed within the socket, but around the base contact terminals.
The second end of the connector can be annular, and can be substantially similar in diameter to the inner dimensions of the socket, such that it can be placed therein In use. The magnet on the connector can also be annular in shape, so as to co-operate with the piece of magnetic metal in use.
The socket can be provided with guide ribs, and the second end of the connector can be provided with co-operating guide slots. Preferably there can be two guide ribs and two guide slots, which are arranged 180 degrees apart on the annular shape of the socket and the second end of the connector. With this arrangement the connector can only enter the socket at one of two rotational positions, which correspond to the two positions in which the base contact terminals and the first contact terminals are aligned.
As described above, the invention does include a version of the fitting in which there is no connector, and a magnet Is be disposed directly on one of the base or the light bulb, and a piece of magnetic metal is disposed on the other of the base or the light bulb. With such a version a new form a light bulb is required which carries either a magnet or a piece of magnetic metal.
Therefore, according to a second aspect of the present invention a light bulb is provided with means to attach to a light bulb fitting with which it is to be used, by means of a magnet.
In one construction the means to attach to a light bulb fitting can comprise a piece of magnetic metal, adapted to attach to a magnet provided on a light bulb fitting with which the light bulb is to be used.
In an alternative construction the means to attach to a light bulb fitting can comprise a magnet, adapted to attach to a piece of magnetic metal provided on a light bulb fitting with which the light bulb is to be used.
The invention can be preformed in various ways, but one embodiment will now be described by way of example and with reference to the accompanying drawings, in which: Figure 1 Is a cross-sectonal side view of a light bulb fitting according to the present invention; and, Figure 2 is a crosssectional side view of the light bulb fitting as shown in Figure 1 in use.
As shown n the Figures a lght bulb fitting 1 comprises a base 2 connected n use to an electricity supply, light bulb attachment means, (in the form of connector 3, spring-loaded bayonet fitting 4, magnet 6 and piece of magnetic metal 12,) and electricity conducting means, (in the form of base contact terminals 9 and 10 and conducting rods 15 and 16), in which in use a light bulb 7 is attached to the light bulb attachment means (4 and 12) by means of a magnet (6), and in which when said light bulb 7 is attached to the light bulb attachment means (4 and 12) in use, the electricity conducting means (9, 10 15 and 16) supplies electricity from said electricity supply to said light bulb 7.
The light bulb fitting 1 comprises base 2 and a connector 3. The connector 3 is provided with secondary light bulb attachment means, in the form of spring-loaded bayonet fitting 4 at a first end 5. The base 2 and the connector 3 are connectable by means of magnet 6, which is provided at a second end 14 of the connector 3.
The base 2 comprises a known type of mains electricity connection means which is not further described here, a cover portion 8 which covers the mains electricity connection means, a pair of base contact terminals 9 and 10, a socket 11, and an annular piece of magnetic metal 12 at the base 13 of the socket 11. The base 2 is connected to a ceiling 40.
The connector 3 further comprises a pair of conducting rods 15 and 16, which each have a first contact terminal 17 and 18 at a first end 19 and 20, and a second contact terminal 21 and 22 at a second end 23 and 24.
Therefore, electricity conducting means extends from said electricity supply to the light bulb 7 when it is attached to the connector 3 and the connector 3 is connected to the base 2.
The conducting rods 15 and 16 are spring loaded as part of the springloaded bayonet fitting mechanism 4. Each conducting rod 15 and 16 is provided with a flange 25 and 26, and coil springs 27 and 28 are mounted n compression against the flanges 25 and 26. The conducting rods 15 and 16 and their associated coil springs 27 and 28 are disposed inside annular passages 29 and 30 running through the connector 3. The annular passages 29 and 30 are provided with stop rings 31 and 32 at one end, which prevent the flanges 25 and 26 passing, and the conducting rods 15 and 16 being pushed out by the coil springs 27 and 28.
The socket 11 is annular in shape, and surrounds the base contact terminals 9 and 10. The piece of magnetic metal 12 is also annular, and is disposed within the socket 11 and around the base contact terminals 9 and 10.
The second end 14 of the connector 3 is also annular, and has a substantially similar diameter to the inner dimensions of the socket 11, such that it can be placed therein in use (as shown in Figure 2 and described below). The magnet 6 on the connector is also annular in shape, so as to co-operate with the piece of magnetic material 12 in use.
The socket 11 is provided with guide ribs 33 and 34, and the second end 14 of the connector 3 is provided with co-operating guide slots 35 and 36. The guide ribs 33 and 34 and the guide slots 35 and 36 are arranged 180 degrees apart on the annular shape of the socket 11 and the second end 14 of the connector 3. With this arrangement the connector 3 can only enter the socket 11 at one of two rotational positions, which correspond to the two positions in which the base contact terminals 9 and 10 and the first contact terminals 17 and 18 are aligned (as shown in Figure 2 and described below).
In use the connector is connected to a light bulb 7 by means of the spring- loaded bayonet fitting 4. The light bulb 7 is pushed into the fitting 4 and against the conducting rods 15 and 16, which act against it by virtue of the force applied to the flanges 25 and 26 by the coil springs 27 and 28. The light bulb is then rotated until its bayonet fitting pins (not shown) are disposed at the ends of the bayonet slots 37 (only one of which is visible n Figure 1). In this position the light bulb contact terminals 38 and 39 are in spring loaded contact with the second contact terminals 21 and 22.
As a result of this connection between the light bulb 7 and the connector 3, the conducting rods are pushed down the passages 29 and 30, to the position as shown in Figure 2. In this position, the first contact terminals 17 and 18 protrude from the second end 14 of the connector 3, and are flush with the magnet 6.
Once the light bulb 7 has been readily fitted to the connector, it can be easily slotted into the base 2 for use.
The connector 3 is offered up to the base 2, and the magnet 6 is attracted to the piece of metal 12. Once the magnet 6 is close enough to the piece of metal 12, the connector is drawn into the socket 11, until it contacts it, as shown in Figure 2.
When the connector 3 is fitted to the base 2 as shown in Figure 2, the first contact terminals 17 and 18 are in contact with the base terminals 9 and 10, and the light bulb can be operated by an electricity supply provided to the base 2.
To replace the light bulb 7 it is simply pulled free and the connector 3 attached to a replacement light bulb 7 and fitted as described above.
The embodiment can be altered without departing from the spirit of the invention. For example, in one alternative embodiment (not shown) the bayonet fitting is replaced with a screw thread fitting. In that case the spring loaded conducting rods are replaced with the known screw thread arrangement where one terminal is located at the bottom of the fitting, and the other terminal is formed by the screw thread contact itself.
ln a further alternative embodiment (not shown) the first contact terminals and the second contact terminals are both spring loaded. In this arrangement each of the conducting rods 15 and 16 of the light bulb fitting 1 are replaced with two conducting rods with a cold spring mounted in compression between them, such that they act against each other. In this embodiment when the connector is connected to the base, the first contact terminals are in spring-loaded connection with the base contact terminals.
In one other alternative embodiment (not shown) falling within the scope of the invention, the connector 3 is not used, and the fitting connects directly to a light bulb by means of a magnet. The magnet is disposed on one of the base or the light bulb, and a piece of magnetic metal is disposed on the other of the base or the light bulb. Therefore, a light bulb according to the second aspect of the present invention is used in this embodiment.
Thus a light bulb fitting is provided which allows very easy fitting and removal of light bulbs in awkward to reach fitting points.
