| 454270000 | Sleeved vent for ceiling, wall, or floor (e.g., thimble) | 7 |
| 20100227543 | VENT STRUCTURE AND METHOD OF MANUFACTURING THE SAME - A vent structure includes: a first housing component having an opening portion for ventilation; a gas-permeable membrane that is attached to the first housing component to close the opening portion; and a laser welding portion that joins the first housing component with the gas-permeable membrane. The gas-permeable membrane includes a main body including a fluororesin film and a porous resin sheet that is laid on the main body. The porous resin sheet is located on the surface side of the vent structure. Both of the main body and the outer peripheral portion of the porous resin sheet that projects outwardly from the main body are fixed to the first housing component by the laser welding portion. | 09-09-2010 |
| 20120115409 | SMOKING ROOM WITH THE AIR RENEWED BY A LAMINAR FLOW - A relaxation space, particularly a smoking room, of the type including elements for renewing the air which elements are provided with supply elements ( | 05-10-2012 |
| 454271000 | Wall type | 5 |
| 20090017748 | LOUVER MODULE - A louver module includes a louver module body that extends in a length-wise direction, a width-wise direction and a height-wise direction such that the length-wise direction, the width wise-direction and the height wise direction are oriented perpendicularly relative to one another. The louver module body has a plurality of air passageways extending through the louver module body generally in the width-wise direction. Each one of the plurality of air passageways has a serpentine configuration. | 01-15-2009 |
| 20090233538 | Foundation Door-Vent with Insulation - InsulVent, the insulated foundation vent, is a crawl-space foundation vent that is designed to open from the exterior as a door. This allows the homeowner to easily open the vent to install insulation during cold weather and remove it during warm weather. The vent is unique because no other foundation vent is designed to open and close from the outside as a door. In addition to a removeable insulation block, the varmint screen is also removeable and replaceable. The door is designed to operate without hinges; however, a hinged version can easily be adapted. | 09-17-2009 |
| 20090239462 | Replaceable foundation vent - The replaceable foundation vent has a mounting frame and a plurality of vent components, including a screen, ventilation plate, and a slider. The ventilation components are removably attachable to the mounting frame using fasteners. The mounting frame has a built in lintel, the entire frame being adapted for permanent mounting in an opening in a block, brick or frame foundation wall. Overhanging portions of the frame lintel rest atop foundation wall members laterally disposed on either side of the frame. Additional foundation wall members can be disposed on top of the lintel to seal off the initial top opening. By releasing/removing the fasteners, the vent components can easily be removed from the mounting frame for repairs to the vent when necessary. | 09-24-2009 |
| 20100112928 | ADAPTABLE EXHAUST BOX - An air exhaust box, for mounting in an exterior building wall and connecting to at least one exhaust duct, includes: a housing having side walls, a rear wall and a front exhaust opening; the front opening having a mounting flange surrounding a periphery of the opening and extending outwardly from the side walls; the rear wall having an inlet opening greater than a predetermined maximum dimension; each of the side walls being joined to the rear wall at an angle less than 90 degrees; and a duct adapter having a cover removably mountable to the rear wall with removable fasteners, the cover having an outer dimension larger than said maximum dimension of the inlet opening and a rearwardly projecting duct sleeve with an inner opening of size between said maximum dimension and a minimum dimension. | 05-06-2010 |
| 20100120352 | Wall Vent - The present invention is concerned with a wall vent for particular use in a cavity wall of a timber frame building, the vent comprising a tubular body having a circumferential flange at one end and a vented or meshed cover across said end, the flange being disposed at an angle to the body such that when the flange is seated flush against the outer surface of the cavity wall the tubular body slopes upwardly into the cavity to prevent the migration of rain or the like through the vent into the cavity. | 05-13-2010 |
