Definitions

  • the invention relates to an air outlet from a housing with a lower and an upper, each cylindrical housing section.
  • the lower housing section is provided with an inflow opening
  • the upper housing section which is larger in diameter, is provided with outlet flow openings arranged in a uniform distribution over the edge region of a cover.
  • Such an air outlet which is particularly suitable for installation in a cavity floor, is known, for example, from DE-OS 34 17 002.
  • This air outlet has a cylindrical upper housing section, referred to as an air distribution head, below which a lower housing section, referred to as an air inlet pot, is rotatably arranged.
  • a radial connecting piece for connecting an air hose protrudes from the air inlet pot. This makes it possible to always bring the air hose in the floor cavity straight to the air outlet, regardless of the arrangement of feet.
  • the known air outlet has a height-adjustable perforated disc, which serves to change the flow resistance of the air outlet, the change being brought about by rotating the cover.
  • the invention has for its object to provide an air outlet of the type described in such a way that it can be effectively closed and opened in a simple manner without disassembly and reassembly.
  • an overflow cross section from the lower housing section to the upper housing section can be shut off or released in the simplest manner.
  • the closure disk is seated on a pin with its free end pointing downward, which is guided in a sleeve extending from the bottom of the lower housing section, a cylindrical spring being arranged around the pin, with which the disk is directed towards the underside of the Lid is pressable.
  • the closure disk can be held at a distance above the overflow cross section connecting the housing sections, as a result of which the air outlet is activated.
  • a sleeve sits concentrically in the cover, through which the actuating pin can be inserted, by means of which the locking disk can be displaced and locked and unlocked from the top against the action of the cylinder spring, and thus can be displaced from the bottom to the top.
  • the closure disk can optionally be transferred from its upper position, which releases the air outlet, to its lower position, which blocks the air outlet.
  • an embodiment of the invention provides that the disk can be fixed in its lower shut-off position by a grid locking of the pin which is known per se.
  • Such grid locks are used, for example, in ballpoint pens, the ballpoint pen refill being axially displaceable between two end positions and being alternately fixable in one or the other position by a simple push-button operation.
  • the air outlet consists essentially of a lower housing section 1 and an upper housing section 2, which are arranged coaxially to one another, the upper housing section 2 being larger in diameter than the lower housing section 1.
  • the lower housing section 1 is provided with an inflow opening, not shown, through which supply air can flow in from a floor cavity into the air outlet.
  • the upper housing section 2 is closed by a cover 3, in the edge region of which slot-shaped outlet openings 4 are arranged in a uniform distribution.
  • the lower housing section 1 is provided with a concentric sleeve 6 starting from a web 5, in which a pin 7 is guided, which is on the sleeve 6 thereof Pioneering end carries a closure disc 8, which can be shifted from the extended position in FIG. 2 to the position shown in broken lines by means of a coil spring 9 arranged around the pin 7.
  • a sleeve 10 is provided concentrically, through the opening of which an actuating pin (not shown) can be inserted, the shape of which, moreover, no requirements are imposed. If the actuating pin inserted through the sleeve 10 exerts pressure on a raster pin 11 projecting above the locking disk 8 and stored in the pin 7, the locking of the pin 9 is released and the locking disk 8 with the pin 9 is drawn from the drawn into the dot-dash line transferred position shown, whereby the overflow cross section between the lower housing section 1 and the upper housing section 2 is released. By renewed pressure loading of the raster pin 11, the closure disk 8 can be transferred just as easily from the dash-dotted line to the extended position in FIG. 2, so that the overflow cross section between the two housing sections 1 and 2 is blocked and the air outlet thus remains inactive until a renewed displacement of the closure disk 8 is brought about.
