Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

Provided is an X-beam structure including: a plurality of beams extending in X-axis, Y-axis, and Z-axis directions and formed in a lattice pattern and a plurality of cross intersections at which an X-axis beam, a Y-axis beam, and a Z-axis beam meet one another, wherein in the X-beam structure in which a cross section of each beam has the geometry of a right-angled X, and the beam intersections are formed with one continuous beam and the two other joining beams are attached and welded onto the continuous beam.

The invention relates to an end piece (11) of a windshield wiper comprising at least one wiper blade (1). Said end piece (11) has a first part (12) and a second part (13) which are connected to each other by a removable attachment means, and a blocking means (28) for preventing the wiper blade (1) from moving relative to the end piece (11), said blocking means (28) comprising a securing device (33) and an actuating element (51). The securing device (33) is designed to pinch the wiper blade (1) and is subject to a force exerted by the actuating element (51). The end piece is for use in motor vehicles.

A photovoltaic (PV) module framing and coupling system enables the attachment of PV modules to a roof or other mounting surface without requiring the use of separate structural support members which attach directly to and span between multiple PV modules in a formed PV array. The apparatus provides a parallel coupling for securely interlocking the outside surfaces of parallel frame members together in a side to side arrangement to form an array with improved structural load distribution. The coupling may attach to a slot in the frame at substantially any position along the length of the frame thereby enabling the interconnection of adjacent PV modules along both an x and y axis. The apparatus may further provide a rotating portion and locking portion, mounting brackets for direct connection to a mounting surface, grounding teeth, and a twist-lock engagement means for interlocking and aligning PV modules in the array.

The rail skirt system includes a top rail, a skirt that hangs from the top rail, formed from rail bar members connected together at their inner ends by a middle connector tube connectable to a locking support leg, to provide support for the top rail on a side of a shelter. The outer ends of the rail bar members are connected to legs of the shelter by fixed corner connecting brackets.

A node for a solar frame including an elongate portion having a channel extending through it in which a structural element is disposed or a solid elongate portion on to which a structural element is disposed. The node comprises a fin extending radially outward from the elongate portion where at least 5% of the volume of the fin is replaced by at least a single void extending essentially in parallel with the channel or the extrusion direction of the solid elongate portion. An apparatus for transmitting torque in a solar frame having structural elements and a support. A system for solar mirrors. A node for a solar frame. A method for connecting a structural element with a strut having a strut end piece of a solar mirror support frame. A method for producing a node for solar mirror frame.

The invention relates to a locking device designed to lock objects to tubes or other elongated elements. The locking device generally comprises one or more lock plates and lock housings. In one exemplary embodiment, when assembling the locking device to a tube, two lock housings are put together with open sides against each other around a tube with a dimension corresponding to approximately half of a recess which is found on the lock housing's sides and are oriented in the tube's axial direction. The two lock housings form a closed geometry around the tube. Lock plates are used to connect the two lock housings together. By applying a screw in a threaded hole in one of the lock housings' cover, the through tube is pressed against an opposite lock housing at substantially the same time as the lock plates hold the lock housings together.
