Locking arrangement and panel system

A panel system, wherein the panel system comprises:

• a lower guide and an upper guide which are essentially parallel;
• at least one panel, which is movable and located between the lower guide and the upper guide and connected to the lower guide and the upper guide for moving the panel on the lower guide;
• a hinge element which is fixed to the panel, located inside the upper guide and allows opening the panel to be opened by turning the panel around a rotation axis;
• at least two locking housings which are in the upper guide and located successively in a longitudinal direction of the upper guide, each of the locking housings comprising two opposite locking recesses, the shapes of which together define a circle with a radius R3, and between which remains a passage having a width P2, the passage being parallel with the longitudinal direction of the upper guide and through which the hinge element can travel from one locking housing to another, wherein a distance between midpoints of the locking housings from one another in the longitudinal direction of the upper guide is a distance P1, which is configured to be less than two times the radius R3,
• wherein the hinge element comprises two locking cams extending in opposite directions, the locking cams rotating with the hinge element around the rotation axis and being configured to extend parallel with the upper guide when the panel is parallel with the upper guide, the locking cams comprising end surfaces, the shapes of the end surfaces defining a circle with a radius R1, the radius R1 corresponding to the radius R3, and the width P2 being less than two times the radius R1, and
• wherein the hinge element comprises a guiding edge remaining between the two locking cams, the guiding edge rotating with the hinge element around the rotation axis and the shape of the guiding edge defining a circle with a radius R2 such that the radius R2 is less than the radius R1, and the radius R2 and the radius R1 together are less than the distance P1.
