Building panels provided with a mechanical locking system

摘要

Building panels, such as floorboards, provided with a mechanical locking system. The mechanical locking system includes a displacement groove at a first edge of a first floorboard and a tongue groove at a second edge of a second floorboard A tongue is arranged in the displacement groove and is configured to cooperate, in a second position, with the tongue groove for vertical locking of the first and the second edge. The tongue includes, in a first position, an inner element and an outer element. The inner element is removable along the displacement groove, and is configured to cooperate with the outer element to obtain a displacement of the outer element towards the tongue groove and thereby obtain the second position. Said inner element and said outer element vertically overlap each other.

1. Panels including at least a first floorboard and a second floorboard provided with a mechanical locking system comprising:
a displacement groove at a first edge of the first floorboard and a tongue groove at a second edge of the second floorboard, a tongue arranged in the displacement groove and configured to cooperate, in a second position, with the tongue groove for vertical locking of the first edge and the second edge, the tongue comprises, in a first position, an inner element and an outer element, the inner element being removable along the displacement groove and configured to cooperate with the outer element to obtain a displacement of the outer element towards the tongue groove and thereby obtain the second position, wherein the displacement groove comprises an opening, an upper wall, a lower wall, a bottom wall connecting the upper wall and the lower wall, and a recess in a first surface adjacent the opening in one of the upper wall and the lower wall, the recess configured to restrain the outer element from being displaced back into the displacement groove after the outer element is pushed into the tongue groove by the inner element, the first surface being angled relative to a second surface adjacent the bottom wall of the one of the upper wall and the lower wall having the recess.
