Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove, which during a horizontal motion is displaced vertically.

A device for locking two building boards comprises a tongue element inserted into a groove a first building board. The tongue element comprises a spring having a plurality of wave arches. A groove is provided in a core of a second building board and corresponds to the groove of the first building board, such that when the groove of the first and second building boards overlap during a connection of the first and second building boards, by a vertical lowering movement, the first and second building boards are locked in a direction parallel to the visible side by the tongue element.

The present invention relates to an adjustable spacer. The spacer includes an elongate member. The spacer includes a sleeve extendable around the elongate member. The elongate member is moveable relative to the sleeve. The sleeve has a locking member. The spacer includes an engaging member configured to selectively engage the locking member for inhibiting movement of the sleeve relative to the elongate member when a desired spacing of the elongate member relative to the sleeve is determined.

A method for joining bodies by melting down a joining element. The joining element acts on a surface of one of the bodies and penetrates the surface as a result of a directed force. Once in a penetrated condition, a mechanical excitation is generated such that during further penetration of the joining element into the one body, the advance is maintained through the directed force and the melting down is maintained through the mechanical excitation. Molten or melted material is hydraulically displaced into the bodies.

A locking system for mechanically joining a plurality of panels or components of an article of construction without the need for glue or other adhesive is provided. The panels are preferably solid hardwood flooring panels. Each panel includes first and second locking members spaced beneath its outer surface. The first locking member is at one side edge of the panel and has two spaced-apart flexible arm portions, at least one arm portion including a first latching member. Preferably, the first latching member is a rib extending outward from the arm portion. The second locking member is at another side edge and includes a channel recessed within the side edge. The channel is sized to receive the arm portions without them having to contact the channel unless deflected within the channel. The second locking member also includes a second latching member positioned and adapted to engage the first latching member. The second latching member is preferably a slot abutting the channel. At least one of the locking members is provided with a positioning member so that upon inserting the first locking member on one panel into the second locking member on another panel for joining them together, the positioning member deflects an arm portion to securely engage the first latching member with the second latching member. The positioning member is preferably a wedge mounted to the back wall of the channel.

A lighting apparatus having a pivotable light cartridge for positioning and directing the light output of a plurality of light sources, the light cartridge including an elongated base oriented along the longitudinal axis, a pivot at the opposed first and second ends of the light cartridge along the longitudinal axis, a plurality of light sources, and an longitudinal wall extending from the lateral edge of the base, the wall including a plurality of spaced-apart, radially-extending ribs, each having a distal edge. A rotatable worm gear having a helical thread is positioned in mechanical engagement with a portion of the distal edges of the plurality of ribs, so that rotation of the worm gear with a hand tool effects pivoting of the light cartridge along the longitudinal axis.
