Rectangular PV modules (6) are mounted on a building roof (4) by mounting stands that are distributed in rows and columns. Each stand comprises a base plate (10) that rests on the building roof (4) and first and second brackets (12, 14) of different height attached to opposite ends of the base plate (10). Each bracket (12, 14) has dual members for supporting two different PV modules (6), and each PV module (6) has a mounting pin (84) adjacent to each of its four corners. Each module (6) is supported by attachment of two of its mounting pins (84) to different first brackets (12), whereby the modules (6) and their supporting stands are able to resist uplift forces resulting from high velocity winds without the base plates (10) being physically attached to the supporting roof structure (4). Preferably the second brackets (14) have a telescoping construction that permits their effective height to vary from less than to substantially the same as that of the first brackets (12).

A vehicle is disclosed having a mast assembly mounted to a sidewall of the vehicle. The mast is pivotally mounted and can be held in a first stowed position by way of a first clamp member. The mast is pivotal relative to the sidewall, to an essentially vertical and erect position, and held in the second position by way of a second clamp.

The present invention provides a method of laying and mechanically joining panels, especially floor panels. In a first step a first panel is already located in a first row. A second panel is positioned in a second row in a first position in relation to the first panel. A third panel is now brought into the second row and into the first position in relation to the first panel. In this position, there is a mutual distance between the adjacent edges of the second and third panel. In a second step the second and third panel are angled into the third mutual position in relation to the first panel. Thereby, the second and third panel each achieve the possibility of easy displacement in the third direction in relation to the first panel. In a third step one or both of the second and third panel are moved in relation to the first panel. By this displacement the second and third panel get in a second position in relation to each other. An additional intermediate step may be employed between the first and the second step. In this intermediate step the second and third panel are angled down into the second mutual position in relation to the first panel.

A method of assembling resilient floorboards is disclosed that includes the step of bending an edge of a floorboard during the assembling. The bending reduces the force required for connection of the edge to another edge of a juxtaposed floorboard.

A process is proposed for laying and mechanically jointing floorboards provided with tongue and groove engagements on all sides for horizontal attachment. The process involves a) jointing of a number of boards and making them engage on their transverse sides n order to lay a first row on the floor of a room, b) jointing of a first board for a second row and making it engage with one or two boards in the first row using the tongue and groove joint on the longitudinal side for the purpose of starting a second row, c) pushing the tongue (or groove) of a second board into the groove (or tongue) on the transverse side of the first board in the second row, with movement from the longitudinal side towards the boards in the first row, and d) making the second board engage with one or two boards in the first row.

Floor panels are shown, which are provided with a mechanical locking system having tongue of magnetic material that could be locked vertically by a magnetic field.
