Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
An air outlet apparatus comprising an air compartment, a plate bounding said air compartment, said plate being provided with openings distributively arranged over its length, each of the openings in the plate possessing an essentially circular-shaped configuration and bounded by an edge means, each of said openings being sealingly occupied by a detachably secured nozzle block, each nozzle block containing a number of protruding nozzles, each nozzle block possessing a flange which engages over the plate and cam means which engage beneath the plate for detachably securing each nozzle block inserted into one of said openings at the plate, the cam means of each nozzle block being formed at the region of a substantially cylindrical portion of the nozzle block which is bounded in axial direction by the flange, and each of the edge means bounding the associated opening in the plate possess recesses which permit the throughpassage of the cam means.
Claim 2
Dependent Claim
152 words
An air outlet apparatus comprising an air compartment, a plate bounding said air compartment, said plate being provided with openings distributively arranged over its length, each of the openings in the plate possessing an essentially circular-shaped configuration and bounded by an edge means, each of said openings being sealingly occupied by a detachably secured nozzle block, each nozzle block containing a number of protruding nozzles, each nozzle block possessing a flange which engages over the plate and cam means which engage beneath the plate for detachably securing each nozzle block inserted into one of said openings at the plate, the cam means of each nozzle block being formed at the region of a substantially cylindrical portion of the nozzle block which is bounded in axial direction by the flange, and each of the edge means bounding the associated opening in the plate possess recesses which permit the throughpassage of the cam means.
Claim 3
Dependent Claim
50 words
The apparatus as defined in claim 1, wherein the cam means are rotatable about an axis of rotation extending substantially in the same direction as the direction of outflow of air through the protruding nozzles of each nozzle block for selectively connecting and disconnecting each nozzle block from the plate.
Claim 4
Dependent Claim
24 words
The apparatus as defined in claim 1, wherein said flange forms an elastically deformable sealing lip which bears with a pre-stress at the plate.
Claim 5
Dependent Claim
15 words
The apparatus as defined in claim 1, wherein said nozzle block is formed of plastic.
Claim 6
Dependent Claim
15 words
The apparatus as defined in claim 1, wherein the nozzle block is formed of metal.
