Description

A DISABLING DEVICE FOR AN ELECTRICAL APPARATUS
The present invention relates to accessories for electrical apparatus.
It is sometimes desirable to prevent unauthorised use of electrical apparatus. Perhaps a computer may contain confidential information to which access must be restricted. Another reason may simply be that the owner ofthe apparatus wishes to prevent others from using the apparatus when he or she is absent, possibly to monitor use ofthe apparatus or to limit the consumption of electricity. Perhaps office managers may wish to restrict employees from using machines such as photocopiers outside office hours.
A known solution has been to design the apparatus to incorporate some form of dedicated disabling mechanism. As an example, personal computers have been provided with a mechanical mechanism which disables the computer and prevents it from booting up. Electrical apparatus have been known to incorporate disabling mechanisms as part ofthe software code. It is common for computerised apparatus to require the entering of a password before the apparatus may be used. The problem with both these earlier approaches is that a dedicated disabling device, designed specifically for one apparatus in particular, may only be used for that apparatus. Hence, such a dedicated disabling device cannot readily be used to disable a range of electrical apparatus.
An object ofthe present invention is to provide a disabling device and method that may be used for disabling a wide range of different electrical apparatus. According to the present invention, there is provided a disabling device for disabling an electrical apparatus that receives electricity via a power plug, said device comprising a lockable container adapted to receive a power plug therein, said container defining an enclosure and being provided with locking means such that when said plug is positioned and locked within said enclosure by means of said locking means, said electrical apparatus is disabled by virtue of its power plug being disabled from being inserted into an electrical power socket.
Preferably, the container is provided with a cover portion moveable between an opened and closed position, such that the cover portion in the opened position reveals on opening through which the power plug is insertable into the enclosure, and the cover portion in the closed position further defines the enclosure.
Preferably, the locking means is adapted to lock the cover portion in the closed position.
Preferably, the locking means is in the form of a cylindrical lock generally contained within a wall ofthe container.
Preferably, the locking means is in the form of a pair of complementary eyelets which are adapted for mutual locking engagement using a conventional lock which is able to pass through the eyelets.
Preferably, the container is provided with an aperture means through which an electric cable for the power plug is able to pass.
Preferably, the aperture means is in the form of an aperture which is partly defined by an indentation on an edge ofthe cover portion, and partly defined by another indentation on an edge ofthe container, such that the indentations define the aperture when the cover portion is in the closed position. Preferably, the enclosure is internally shaped to receive the plug in a snug fitting engagement.
Hence, the lockable container ofthe present invention is able to disable a wide range of electrical apparatus, because it is adapted to disable the component which is common to a wide range of electrical apparatus, namely the electrical power plug.
According to another aspect ofthe invention, there is provided a method of disabling an electrical apparatus that receives electricity via a power plug, comprising the steps of positioning the power plug within an enclosure of a disabling device which enclosure is defined by a lockable container, and locking the power plug within the enclosure by means of locking means provided on the container.
In order that the present invention might be more fully understood, embodiments ofthe invention will be described by way of example only, with reference to the accompanying drawings, in which:
Figure 1 illustrates a schematic diagram of a disabling device constructed in accordance with a first embodiment ofthe invention;
Figures 2A, 2B and 2C illustrate respectively the side view, front view and plan view of the disabling device illustrated in Figure 1. The internal surfaces are shown with dotted lines;
Figure 3 illustrates a schematic diagram of a disabling device constructed in accordance with a second embodiment ofthe invention; Figures 4A, 4B and 4C illustrate respectively the side view, front view and plan view of the disabling device illustrated in Figure 3. The internal surfaces are shown with dotted lines;
Referring to the drawings, Figure 1 illustrates a disabling device for disabling an electrical apparatus that receives electricity via a power plug. The disabling device, in the present embodiment, comprises a container in the form of a box 10. The box 10 is adapted to receive a power plug 20 therein. The power plug 20 is illustrated in Figure 1 only to describe the intended function ofthe invention. A power plug is therefore not an essential feature ofthe invention in its broadest aspect. The box 10 defines an internal enclosure 30. The power plug 20 is able to be positioned within the enclosure 30 ofthe box 10.
The box 10 is provided with a cover portion in the foπn of a cover 50. The cover 50 is connected to the box 10 by a hinge 70, and is able to be pivoted between an opened and closed position. The box 10 is illustrated in Figure 1 in the opened position. In Figures 2A, 2B and 2C, the box 10 is illustrated in the closed position. In its closed position, the cover 50 defines the upper boundary ofthe internal enclosure 30. When the cover 50 is in the opened position, the opening ofthe enclosure 30 is revealed. The plug 20 is able to inserted into the enclosure 30 through the opening.
The box 10 is provided with locking means in the form of a conventional cylinder lock mechanism 40. The locking mechanism of this embodiment is operable by rotation of a key (not shown) therein. However, a number of different locking means may be used, provided that the locking means adequately performs the function of locking the cover 50 in the closed position. Different locks, such as combination locks, may also be used to perform the same locking function. The locking means is generally positioned within a wall ofthe container. The actually location ofthe locking means in relation to the container wall is not critical to the invention in its broadest aspect, so long as the locking means is able to perform the foregoing function. The locking mechanism 40 enables the cover 50 to be locked in the closed position. In use, the power plug 20 is inserted into the enclosure 30, and then locked therein by locking the cover 50 in the closed position. By disabling the power plug in this manner, the apparatus (not shown), which relies on the electrical connection ofthe power plug 20 for its power supply, is thereby effectively disabled. The electrical apparatus is thereby prevented from connecting to an electrical power socket.
The advantage of the disabling device and method ofthe present invention is that by disabling an electrical apparatus at the point ofthe power plug, a range of apparatus may be disabled. The disabling device is therefore not restricted to being used with one particular electrical apparatus.
The box 10 is provided with an aperture means through which an electric cable 80 for the plug 20 is able to pass. The aperture means in the present embodiment is in the form of a pair of indentations, one on each edge ofthe container wall or cover 50. A portion of the aperture means ofthe present embodiment is defined by an indentation 60a on an edge of the container wall. Another portion ofthe aperture means is partly defined by another indentation 60b on an edge ofthe wall ofthe cover 50. When the cover 50 is in the closed position, as illustrated in Figure 2, the pair of indentations 60a, 60b are aligned so as to form an aperture through which the cable ofthe power plug may pass. The invention in its broadest aspect, of course, is not limited to having or using aperture means in this arrangement. It is important merely that the disabling device is provided with an opening that enables the cable ofthe power plug to pass through the wall ofthe container, when the cover portion is in the closed position.
In a second embodiment of the invention, illustrated in Figures 3, 4A, 4B and 4C, the locking means is in the form of a pair of complementary eyelets 100a, 100b which are adapted for mutual locking engagement. A conventional lock is able to pass through the eyelets 100a, 100b in order to lock the cover 50 in the closed position. In further embodiments of the invention, the enclosure 30 is internally shaped or moulded to receive the power plug in a snug fitting engagement. However, this feature is optional as it does not influence the prime function ofthe invention, which is to disable an electrical apparatus at the point ofthe power plug. However, the snug fit is advantageous because it minimises internal noise which may arise when the power plug rattles within the internal enclosure 30.
It is contemplated that a likely use ofthe disabling device ofthe present invention is for parents to disable the use of television sets. This device would enable parents to lock up the power plugs of television sets, to prevent children from unauthorised television viewing.
The embodiments have been advanced by way of example only, and modifications are possible within the scope ofthe appended claims.
