A bottom door of a carriage includes a telescoping cylinder and at least two sets of door bodies, each set of the door body is provided with one set of driving mechanisms, each of the driving mechanisms includes a rotating shaft and a driving rod, and the rotating shaft is connected with the respective door body by the driving rod, to allow the door body to be driven to rotate when the rotating shaft rotates; each of the rotating shaft is driven to rotate by the telescoping cylinder, and at least two of the rotating shafts are configured to be driven to rotate successively by the telescoping cylinder.

A louvre assembly is described for fitment to doors and/or housing structures for the purposes of allowing air spaces either side of doors and/or internally and externally of such housing structures to intermix. The louvre assembly includes a louvre housing having a continuous louvre housing perimeter wall; a louvre housing cavity surroundingly defined and formed by the louvre housing perimeter wall so as to have first and second laterally spaced open faces; and a louvre formation comprising a plural array of louvre slats removably mountable within the louvre housing cavity. The louvre assembly additionally or alternatively further includes a baffle formation removably mountable over said first open face and comprising: an apertured first closure plate associatively engageable with the louvre housing to seat over said first open face; an unapertured baffle box back plate; a baffle box perimeter formation extending between and laterally spacing apart the first closure plate and the baffle box back plate and forming thereby a baffle cavity; the baffle box perimeter formation having at least one apertured portion communicating with the said baffle cavity. Doors and/or housing structures incorporating such louvre assemblies are also described.

A wooden veneer-faced window shutter, comprising a variety of shutter components, wherein the components comprise a blade, a stile, a rail and a frame, wherein the blade, the stile, the rail and the frame comprise a poplar (or other inexpensive soft wood species) FJL/LVL base and a layer of wood veneer face. The said base and veneer face are with E0 glue. This invention is simple in structure. By combing the cheap FJL/LVL base with the relatively expensive veneer face, this invention has the following advantages: first, it reduces the cost of making wood shutters; secondly, it meets the customer's need for window shutters made of expensive wood species; thirdly, it helps solve the shortage of some rare wood species.

A louvered separator for separating water from an air flow is provided which includes a number of vertical slat structures having a constant profile, horizontally spaced from each other so as to form horizontally tortuous separating channels in the spaces between the slats. The slat structures include water-collecting troughs and two separate slats having differing constant profiles; in the air flow direction a foremost front slat and a following back slat. The front slat includes, in the flow direction, a leading edge, a middle area and a trailing edge, and the back slat includes, in the flow direction, a leading edge, a middle area and a trailing edge. The water-collecting trough is limited to the area of the trailing edge of the back slat, so that the front slat entirely, and the back slat for more than a half of its length from the leading edge towards the trailing edge, form only even surfaces to guide the flow.

A slat of a window covering is disclosed, wherein the slat includes a core material and a covering layer covering thereon. The core material is substantially long, and a surface thereof could be divided into two side surfaces and a continuous surface, wherein one of the side surfaces is on one side of the core material in a longitudinal direction, and the other one of the side surfaces is on the other side of the core material in the longitudinal direction. The continuous surface connects the peripheries of the side surfaces. The continuous surface has at least one flat segment provided in the longitudinal direction. The covering layer covers the continuous surface, wherein the covering layer has a greater thickness on the at least one flat segment than on any other parts of the continuous surface.

A slat device (1) comprising a plurality of slats (2) arranged parallel to one another, displacement means (9, 10) for displacing the slats (2) between and in a stacking zone and a sliding, and a guide profile (3), which is arranged on a lateral side of the slats (2), wherein a slat (2), on the said lateral side, is provided with a guide element (5), corresponding with the guide profile (3), for guiding the respective slat (2) relative to the corresponding guide profile (3, 6) during its displacement motion between and in the stacking zone and the sliding zone, such that the guide element (5) is rotatable over a certain angle relative to the guide profile (3) about an axis according to the longitudinal direction of the guide profile (3).

Implementations of a portable soundproofing enclosure may include: four side panels coupled together, a top panel coupled to each of the four side panels, the four side panels and the top panel, the top panel including a fan. The panels may form a cavity sized to fully enclose a portable generator. At least two of the four side panels may include an air dam. At least one of the side panels may have a plurality of louvers configured to allow air to be drawn through the panel. The bottom edges of the sides may be configured to rest on a mat.

A rain-hat system for use on a vehicle that includes a cowling having a fresh air inlet, a rain-hat assembly that includes a body, and a plurality of louvers is disclosed. The body has a back side for attachment to the fresh air inlet. The body also has front side to which the plurality of louvers is attached. The rain-hat assembly also includes a front, a back, a first side, and a second side. At least some of the louvers slope downwardly from the front to the back and at least some of the louvers slope downwardly from the first side to the second side. In addition, at least some of the louvers include a downwardly sloping flange attached at the first side and a downwardly sloping flange attached at the second side. Preferably the uppermost louver has a gutter defined by an upwardly angled lip.
