A panel assembly for installation onto a track beam including a beam flange having a non-linear edge is disclosed. The panel assembly includes a panel and a lockable catch moveably connected to the panel. The lockable catch includes a lockable mating edge configured to selectively mate with the non-linear edge of the beam flange of the track beam. The lockable catch also includes a lockable catch edge extending beyond the lockable mating edge. The lockable catch is moveable on a lower surface of the panel between an unlocked position and a locked position. In the unlocked position the lockable catch edge is retracted. In the locked position, the lockable mating edge mates with the non-linear edge of the beam flange and the lockable catch edge retains the panel on the track beam.

A flexible shoulder pin module includes a barrel having an annular head portion, a cylindrical body portion, and a through-hole extending from a top surface of the body portion to a bottom end of the head portion; and a shoulder pin having a shaft portion and a shoulder portion formed thereon. The through-hole includes a first portion adjacent to the top surface of the body portion, and a second portion having a greater diameter than the first portion. The shaft portion is insertable through the first portion into the second portion. The shoulder portion is configured to adjustably extend above the top surface of the body portion to clamp a panel thereto. A compressible device is configured to be disposed around the shaft portion and secured by a stopper panel, which is coupled to the shaft portion and placed adjacent to the head portion within the second portion.

A first unit (100) including a first member (110) of a releasable fastening arrangement (300) is presented. The releasable fastening arrangement (300) is arranged to provide a mechanical connection of the first unit (100) to a second unit (200), and an electrical connection of a first electrical circuit (120) included in the first unit (100) to a second electrical circuit (220) included in the second unit (200), when a male profile (115) of the first member (110) is inserted into a corresponding female profile (215) included in a second member (210) of the second unit (200). The mechanical connection is provided based one or more at least partially resilient latching arm members (117) of the male profile (115) engaging with one or more corresponding slots (217) of the corresponding female profile (215). The electrical connection is provided by contact between one or more first flexible conductors (124) arranged on a first flexible and electrically insulating layer (126) of the first electrical circuit (120) and one or more second flexible conductors (224) arranged on a second flexible and electrically insulating layer (226) of the second electrical circuit (220).

A PV module alignment or attachment system and method that contains multi-connectors that interact with the modules along rows or columns of an array of the modules. In some versions, the multi-connectors connect to frames of the modules in a row or column and maintain the module-to-module height between modules. The multi-connectors connect to flanges on the frames, which flanges are molded into the frames or bolted to the frames.

In an example, a clamp assembly for a glass on glass solar module for a tracker is included. The assembly has a lower clamp structure characterized by a top-hat shaped rail structure having a length extending from a first end to a second end. In an example, the assembly has an upper clamp structure configured to sandwich a pair of edges of a pair of solar modules with a portion of the lower clamp structure. In an example, the assembly has a locking spacer configured to the pair of edges of the pair of solar modules. In an example, the pair of edges comprises substantially glass material. In an example, the assembly has a pair of key structures configured with the locking spacer. Each of the key structures is affixed to each of the solar modules to physically lock each of the solar modules to the upper clamp structure.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more board engagement elements extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a groove of the board, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.

A grill cover is configured to be utilized with a grill having a metallic component, the grill cover includes a cover body, a magnetic fastener, and a secondary fastener. The cover body presents an outer edge disposed along a bottom side and a cover void therein configured to receive the grill therein. The magnetic fastener and the secondary fastener are each secured to the cover body. The magnetic fastener is configured to provide a magnetic force to keep the magnetic fastener selectively secured to the metallic component of the grill so as to keep the cover body in place around the grill therein. The secondary fastener is configured to reduce a cross-sectional area of the cover void so as to prevent the grill cover from being removed from the grill while the secondary fastener is emplaced.

A fastening system for fastening in a receptacle of a carrier component includes a fastening element with a guide portion insertable into the receptacle along a direction of insertion, and a clip element which is plugged onto the guide portion and which, to hold the fastening element and clip element in the receptacle, has retaining edges which interact with an inner surface of the receptacle, wherein the guide portion and clip element have interacting latching portions formed in such a way that an axial pulling force to release the fastening element and clip element from the receptacle produces a radially outwardly acting force on the retaining edges of the clip element, wherein the fastening element and the clip element further have interacting stop portions which counteract release of the clip element from the fastening element.

Connectors, systems with connectors and processes with connectors are described. These include how connectors can actively hold external portions of two frames or other components together during transport and before final installation, as well as, how the connectors can be repositionable on the frame or other component so as to provide a mechanical connection in one position and not to provide a mechanical connection when moved into a second position. The connectors can also function to provide spacing or alignment or both between frames or other components grouped together using the connectors.
