  • Patent number: 6568823
    Abstract: The invention relates to a remote access system designed to make the task of positioning, manipulation and/or maintenance of devices, which are difficult to access or in hostile environments, a much easier operation. The system comprises remote manipulation whereby a device (420), such as a bulb, may be moved from a remote access position (200) along a guide (300) to an enclosure position (100). The enclosure position may, for instance, comprise an area formed in the side wall of a swimming pool, such that, a lens (120) of the enclosure sure (100) is arranged, in use, to have the device (420) to one side of it, and, sealed from the device on the other side of the lens (120), there may be water. By providing an arrangement whereby the device (420) can be remotely positioned, the need for draining a swimming pool for the simple replacement of blown bulbs etc. is avoided.
