A structure is provided which includes first and second layers. The first and second layers are attached to each other by embedding or otherwise attaching at least one mechanically locking z pin to the first layer and then subsequently joining the protruding portion of the z pin to the second layer prior to the second layer being processed to a fully cured state. Alternatively, the z pin material is injected into a cavity formed in the first and second layer and then brought to a fully cured state. The z pin may have physical characteristics such as orientation, melting point and hardness as a function of the physical characteristics of the first and second layer and the forces subjected upon the first and second layers. For example, the z pin may define a longitudinal axis and be embedded within the first and second layers in alignment with an applied force subjected on the first and second layers. This ensures that the z-pin is subjected primarily to tensile forces which allows designs to better control the failure mode of the attached first and second layers.

The invention concerns a system comprising at least two panels, particularly floor panels for forming a covering. The panels have first and second lateral edges, which can be connected by a movement substantially perpendicular to the covering.

The present invention provides a fastener capable of preventing refuse and moisture from entering, raising an extraction force for a pin, and reducing insertion resistance in inserting the pin. Since a base 26 of a grommet 16 is formed in a bag shape, refuse and moisture do not enter into the base 26. Accordingly, water content does not ooze from the base 26 to a floor carpet 14 through an insertion hole 22 of the grommet 16. Also, a through hole 24 is formed in a flange 20 along a direction crossingly perpendicular to the axial direction of the grommet 16, and the flange 20 is divided into an upper part 20A and a lower part 20B. Accordingly, a locking claw 38 or a locking claw 40 can be locked to the upper part 20A. Since the upper part 20A of the flange 20 is recessed along a direction perpendicularly crossing the axial direction of the grommet 16, an extraction force can be increased more than in the case that the upper part 20A is formed in a tilted state relative to the axial direction of the grommet 16 despite the fact that the insertion resistance for the pin 18 is approximately the same.
