Abstract
The invention relates to flat and/or elongated building components (1, 2), preferably wooden, and a structure connecting these components (1, 2) in accordance with the groove and tongue principle. Two legs (3, 4) forming a groove (5) branch off from a front face of one of the components (1), and a tongue (6) branching off from a front face of the other component (2) can be inserted into the groove (5). Locking elements (7, 8) hold the components (1, 2) in an assembled position. In accordance with the invention, the locking elements are configured as triangular projections (7) and cavities (8) in facing or adjacent surfaces of the groove and/or tongue.
Claims23
An arrangement of panel shaped or strip shaped building members made of wood, wood material or wood based material, comprising:
- first and second components each having a top surface, a bottom surface and at least one edge face,
- a groove defining an opening through at least one edge face of the first component,
- the groove having first and second walls extending from the opening in the component and inwardly converging at first oblique angles toward a groove bottom with the first and second walls each having an outer portion of a selected extent and an inner portion;
- first and second contact surfaces disposed at the outer portion of the first and second walls, the first and second contact surfaces converging at oblique angles from the outer portions of the walls with respect to planes defined by the top and bottom surfaces of the first component, the contact surfaces having extents less than and oblique angles steeper than the outer portions of the walls;
- a tongue projecting from the at least one edge of the second component for receipt through the opening when the edges of the components are in abutment;
- the tongue having first and second opposed surfaces for abutting the first and second walls of the groove when inserted into the groove, the first and second surfaces having at least inner portions abutting and complementing the outer portions of the first and second walls, and shoulders abutting and complementing the contact surfaces on the outer portions of first and second walls to positively retain the tongue in the groove.
An arrangement of floor panels made of wood, wood material or wood based material, comprising:
- first and second components each having a top surface, a bottom surface and at least one edge face;
- a groove defining an opening through the at least one edge face of the first component, the groove having upper and lower walls when the top and bottom surfaces of the first component extend horizontally, the upper and lower walls of the groove extending from the opening in the edge of the first component inwardly toward a bottom wall within the groove, at least the lower wall of the groove converging toward the upper wall and the lower wall of the groove having an outer portion of selected extent and a flat inner portion extending from the bottom wall toward the outer portion with the outer portion converging at a steeper angle than the inner portion;
- a contact surface on the outer portion of the lower wall disposed proximate the opening of the groove and extending obliquely from the lower wall with respect to the top and the bottom surfaces of the first component in a convergent direction with respect to the opening of the groove, the contact surface having an extent less than the outer portion of the lower wall, and
- and a tongue projecting from the at least one edge of the second component for receipt through the opening when the edges of the components are in abutment, the tongue having a top surface for abutting the upper wall of the groove when inserted into the groove, a bottom surface having at least an inner portion abutting and complementing the outer portion of the lower wall and a shoulder abutting and complementing the contact surface to positively retain the tongue in the groove.
