Linear guide device

A linear guide device comprising:

• a guide carriage featuring a carriage base body which has two guide units arranged in succession in a carriage longitudinal direction, each guide unit having a first guide module arranged on the carriage base body and a second guide module arranged on the carriage base body at a distance opposite to the first guide module in a carriage transverse direction orthogonal to the carriage longitudinal direction,
• wherein the guide carriage, in its operating position, is supported linearly movably on a base structure in the carriage longitudinal direction, wherein the two first guide modules bear against a first guide surface and the two second guide modules bear against a second guide surface of the base structure so as to be movable with respect thereto,
• wherein one of the two guide modules of each guide unit is an adjustable guide module, and each of the two guide units is provided with an adjustment unit, the adjustment units being arranged in succession in the carriage longitudinal direction, by means of which the associated adjustable guide module is adjustable by an adjusting force to cause a movement oriented in the carriage transverse direction, relative to the carriage base body,
• whereby a pretension is adjustable by adjusting the guide modules with the adjusting force with which the two guide modules of the guide unit are pressed against the respectively associated first or second guide surface of the base structure in the operating position of the guide carriage, and
• wherein the guide carriage features a central actuating device drivingly coupled to the adjustment units of both guide units, through the actuation of which synchronous adjusting forces can be exerted on the two adjustable guide modules.
