Panel e.g. floor panel, has lower slot bevel corresponding to inclination angle of upper side of front side rounded spring that is relegated with respect to longitudinal side of slot

摘要

The panel (1) has a slot (9) hollow at an upper circumferential region (10) that is adjacent to a panel upper side (5). The slot is opened in a longitudinal side over a rounded bulge (12) pointing to a panel lower side (6) at an upper spring (7). Another spring (19) has an upper convex surface section (20) adapted to the region, and a lower slot bevel at a lower front section (25) that forms an upper side of another slot (27). The bevel corresponds to an inclination angle of an upper side (14) of a front side rounded spring (8) that is relegated with respect to the longitudinal side.
