Structural assemblies using integrally molded, and welded mechanically locking z-pins

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 first lateral edge has a locking member coupled to a spring so that an inner position exerts a restoring force on the locking member in the direction of the outer position. The second lateral edge has a locking element that cooperates with the locking member. The locking member and locking element each have a locking face. To withstand higher vertical extraction forces, the first and second lateral edges are designed to connect by a movement directed from top to bottom of the second lateral edge, and the locking faces, when connected, lock the second lateral edge against upward lifting, while the locking member is supported with respect to the panel.

Fixing device

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.
