Installation position pointer system

An installation position pointer system to indicate a position in a building where an attachment is to be installed, the installation position pointer system comprises:

• a mounting platform;
• a stand to support the mounting platform;
• a laser source, mounted on the mounting platform to project a colored laser beam at least in one direction, wherein the laser source consists of a single laser source;
• a driving device mounted on the mounting platform and coupled with the laser source, to drive the laser source in a planar direction and a tilt direction in order to align the laser beam emitted by the laser source to a computed direction;
• a memory device for storing a code number and an installation position data (IPD) of each of a plurality of attachments, wherein the IPD relates to spatial configurations of a floor unit of a building;
• and
• a control device coupled with the driving device, to obtain the IPD of one attachment at a time from the memory device according to the code number of the attachment, and to control the driving device to drive the laser source to project a laser beam at the installation position according to the position data and a reference position associated with the attachment;
• wherein the mounting platform comprises a baffle to abut against a corner of two partition walls of the floor unit and to define a direction of extension of the two partition walls, so to provide the reference position information to the control device;
• whereby, by positioning the installation position pointer system at the corner of the two partition walls of the floor unit, with the baffle of the mounting platform abutting against the corner of the two partition walls, followed by providing a code number of an attachment to the control device, the control device controls the driving device to drive the single laser source to project a laser beam at the installation position of the attachment, wherein the position in the building where the attachment is to be installed is indicated by the single laser source.
