Definitions
- This invention relates to apparatus facilitating the use of a battery, and to a method of using the battery, for example in electrical equipment with a battery compartment for one or more batteries of particular sizes.
- Battery-operated electrical devices and appliances usually accommodate one or more batteries in a compartment, and the compartment is designed to accommodate and retain batteries only of one specific standard size.
- These standard sizes are known commercially as AAA, AA, C and D cells, in particular, and the approximate outer diameters and lengths of these batteries are as follows:
- Examples of battery-operated equipment include remote controllers, personal audio players, pocket memos, radios, televisions, camcorders, torches and toothbrushes. Some of these take just one battery, but many take two or more batteries, usually of the same size.
- the present invention is intended to solve this problem in certain situations.
- the invention has arisen from this observation, and provides a battery adaptor consisting of a hollow tube whose inner and outer diameters match two standard commercial battery outer diameters respectively and whose length matches the length of at least one of those standard commercial batteries.
- the battery adaptor can therefore effectively enlarge the diameter of a smaller battery to enable it fit a compartment intended for a larger battery.
- the battery adaptor may comprise a closed end with an electrically conductive end, such as a plate, connected to an axially resiliently deformable internal connector.
- the overall length to the end matches the length of one standard commercial battery and the inner length to the connector matches the length of another, smaller, standard commercial battery.
- the battery adaptors will be sold in sets, in some cases the members of the set all being the same size, but in other cases the members of the set including adaptors of different sizes so that they can nest within each other. Appropriate sets of adaptors would therefore be devised to meet the potential need for a plurality of equally sized batteries, or a number of differently sized batteries, or a mixture.
- the adaptors would typically be sold together with batteries of standard commercial size, and/or with electrical appliances such as torches.
- the tube or tubes are preferably of plastics.
- the invention provides a corresponding method of accommodating and retaining a battery in a compartment intended for a larger battery, comprising inserting the battery lengthwise into an adaptor according to the invention as defined above such that there is a snug fit, the adaptor matching the size of the intended larger battery, and inserting the adaptor in the compartment.
- Figure 1 is an axial section across the diameter of a battery adaptor embodying the invention
- Figure 2 is a side view of a standard commercial battery which fits snugly within the adaptor of figure 1 so that it can be. used in place of the standard commercial battery on figure 4;
- Figure 3 is a view corresponding to figure 1 , but of a larger battery adaptor, intended to accommodate snugly the battery of figure 4 so that it can be used in place of the battery of figure 6;
- Figure 4 is a view corresponding to figure 2, of a standard commercial battery
- Figure 5 is a view corresponding to that of figures 1 and 3, of a still larger battery adaptor embodying the invention, and intended to accommodate the battery of figure 6;
- Figure 6 is a view corresponding to figures 2 and 4, of a larger standard commercial battery.
- a nesting set of three adaptors embodying the invention is intended to be used selectively to adapt a AAA cell for use as a AA cell and/or a AA cell to be used as a C cell and/or a C cell to be used as a D cell.
- the standard commercial AAA cell is shown in figure 2, and it is intended to fit snugly into the tubular plastics adaptor of figure 1 , which is about 5 mm longer and whose inner diameter matches the outer diameter of the cell.
- the open end of the tube exposes the positive end terminal of the cell for normal connection in use.
- the other end is closed by an electrically conductive cap or plate 11 to which is bonded a cylindrical compression spring 10 for establishing a good contact with the negative battery terminal when fully inserted.
- the standard AA cell is shown in figure 4, and is intended to fit snugly, in a similar way, into the tubular adaptor of figure 3, whose outer diameter matches that of a C cell, as shown in figure 6.
- the adaptor of figure 3 is open-ended at both ends, because AA and C cells have the same length so no length adaptation is required.
- Standard C and D cells have different lengths, and in order to adapt a C cell, as shown in figure 6, for use as a D cell, the adaptor of figure 5 has a closed end with an electrically conductive end plate 1 connected electrically to an axially resiliently deformable internal connector, in the form of a spiral spring 2. When inserted into the adaptor of figure 5, the cell of figure 6 deforms the spring 2, to establish a good electrical connection.
- two or more of the adaptors of figures 1 , 3 and 5 may be used in the nested configuration, to provide a further level of adaptation.
- the AAA cell of figure 2 could be used as though it were a standard commercial D cell, by inserting it into all three nested adaptors.
- the tubes are preferably of plastics material, such as PTFE, but any appropriate material could be used, conductive or non-conductive. A degree of resilient deformability is desirable, in order to provide a snug friction fit between the battery and the adaptor, and between the adaptor and any nested adaptors. Whilst the tubes may be of solid construction as illustrated, this is not essential, and they could have an open construction, for example using radial walls dividing the space into cells, or using a material which has an open structure such as expanded polystyrene.
- the adaptor or sets of adaptors would typically be sold adjacent to batteries, or as a kit with batteries or with torches or other appliances. . In this sense, they are regarded as complementary accessories.
