<p>#CMT# #/CMT# The device has structural panels (1, 2) with upper and lower sides and profiles (10, 11) provided at side edges. A locking element (3) with a locking projection (7) is provided in the profile (11). The element cooperates with a locking recess (4) provided in the profile (10) such that the panels are automatically locked in a vertical direction during a joining movement. The locking element is rigidly formed and the locking projection is brought into the recess by a rotary motion of the element that is made of metal or timber material-plastic mixture e.g. high or medium density fiber board. #CMT#USE : #/CMT# Device for connecting and sealing structural panels i.e. floor panels (claimed). #CMT#ADVANTAGE : #/CMT# The locking element is rigidly formed and the locking projection is brought into the locking recess by the rotary motion of the locking element, so that the two structural panels can be locked in a safe manner with a high extraction force and without the need for a spring unit. The locking element can be manufactured in an inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of two structural panels at a connecting point, with a locking element. 1, 2 : Structural panels 3 : Locking element 4 : Locking recess 7 : Locking projection 10, 11 : Profiles 16 : Groove 17 : Core.</p> |
