Claims

1. A linear guide device, comprising a guide rail system with at least one guide rail; a guide carriage guided on said guide rail system in a guidance direction and including a base unit and legs which partially enclose said guide rail system, said guide carriage being provided with at least one preload-adjustment device via which a preload of said legs of guide carriage against said guide rail system is adjustable, said preload-adjustment device including at least one rod having one end hingedly mounted on one of said legs of said guide carriage and the other end displaceable in a displacement direction; and a displacement device for displacing said other end of said preload-adjustment device in the displacement direction.

2. A linear guide device as defined in claim 1, wherein said rod extends at an angle of substantially from 0° to 45° relative to a transverse direction of said guide rail system orthogonally to said guidance direction.

3. A linear guide device as defined in claim 1, wherein said adjustment device includes an engagement part on which said other end of said rod is hingedly mounted.

4. A linear guide device as defined in claim 1, wherein said displacement device includes a screw which bears against an element selected from the group consisting of said base unit of said guide carriage and an engagement part, and engages in a thread formed in an element selected from the group consisting of said engagement part and said base unit of said guide carriage.

5. A linear guide device as defined in claim 4; and further comprising a second rod provided between said engagement part and said base unit and forming a knee joint together with said first mentioned rod and said engagement part.

6. A linear guide device as defined in claim 5, wherein at least one element selected from the group consisting of said first mentioned rod, said second rod, said engagement part and a combination thereof, is formed integral with said guide carriage.

7. A linear guide device as defined in claim 1; and further comprising joint means including hinge joints provided between two elements selected from the group consisting of an engagement part and said at least one rod, and said at leat one rod and said leg or said base unit of said guide carriage, and formed via material reduction.

8. A linear guide device as defined in claim 1, wherein said guide rail system includes a second guide rail so that said guide rail system has two guide rails.

9. A linear guide device as defined in claim 8, wherein said at least one preload-adjustment device is assigned to only one of said guide rails.

10. A linear guide device as defined in claim 1; and further comprising another preload-adjustment device, so that at least two preload-adjustment device are provided and separated in a longitudinal direction of said guide rail system and assigned to a same leg of said guide carriage.

11. A linear guide device as defined in claim 1; and further comprising at least one rolling element circuit through which said legs are engaged with said guide rail system.
