Abstract

A roof ventilating device (D) has a roofing slab (1) with a dome (2) provided with a top opening for a ventilating pipe (5) whose diameter approximately corresponds to the width of the dome (2) and is smaller than its length. A cap (6) that covers the dome (2) has a vent. In order to optimise the operation and the construction of the device, the vent in the cap (6) comprises a ventilation grid (9/Ö) that extends beyond the opening of the ventilating pipe. The larger, longitudinal diameter of the ventilation grid (9/Ö) runs into the circular cross-section of the ventilating pipe (5) through funnel-shaped (funnel T) sliding surfaces (13, 14).

Description

00001 roof vent 00002

00003 The invention relates to a roof covering

00004 plate designed roof vent with a medium-sized

00005 gen, dome-shaped cathedral, which is taller in height

00006 as its width and less than its length,

00007 and the top has an opening for passage

00008 of a ventilation connection pipe, the diameter of which is approximately

00009 corresponds to the width of the cathedral and is smaller than

00010 its length, and which one the top of the cathedral

00011 overlaying cap, which in the apex area

Has 00012 air passage hole and covering the

00013 extends the distance that the ventilation connection pipe

Leaves the length of the cathedral towards the cathedral edge, whereby

00015 the hole of the cap than itself up over the clearance area

00016 extending ventilation grille opening is designed and

00017 the larger, longitudinal diameter of the ventilation grille

00018 ter opening via a funnel-shaped sliding surface in the

00019 circular cross section of the ventilation connection pipe

00020 is running. 00021

00022 A roof vent of this type is through the European

00023 patent application 0 454 900 known. Such one

00024 inclination adjustment matched roof

00025 cover plates form both technically and

00026 functionally the basic type of a variable roof accessory

00027 hearing (e.g. breather, antenna carrier feedthrough). There

With such roofing slabs, an elongated hole in the cathedral

00029 is required, the inexpensive basic

00030 condition before, the cross section of the circular ventilation

00031 connecting pipe in the area of the opening of the dome

To train 00032 cut larger. Such a cross-sectional

00033 increase falls in its ventilation effectiveness itself

00034 then still significant if an inclination adjustment

00035 is aimed, so the usual cap the elongated hole 00036 dimension bridged movable, compare Figure 9 of the

00037 th EP-OS. A solution can also be found from the same,

00038 integrally molded after the dome and ventilation connection pipe

Are 00039. The desired low fan is in both cases

00040 before, which can optionally be covered with a cover cap

00041 can be. But because of the se i-spherical

00042 creates the opening from the apex in the two end

00043 range more or less towards the foot

00044 of the cathedral falls, is

00045 cover plates, which have a strongly relief-like profile

00046 have something in the case of low fans that require covering

00047 greater clearance or overhang of the cathedral desired. 00048

The object of the invention is to provide a generic

00050 roof vent while maintaining the advantageous basic

00051 condition in such a way that with structural, i.e. also

00052 technically simple means a larger projection

00053 is reached. 00054

00055 This object is achieved by the

00056 bene invention. 00057

In the further claims, preferred configurations follow.

00059 operations. 00060

According to such design is using the

00062 slot as an optimal ventilation cross section

00063 longer overhang length achieved by between

00064 elliptical perforated edge and ventilation grille level this one

00065 connecting upward facing collar

00066 stretches. The basic shape of the cathedral remains; he is from

00067 hole edge extended starting. Still as a low fan

To classify 00068, is now a larger one with extreme flow

00069 does not overflow supernatant. These outcomes

00070 design can be mastered well in terms of molding technology 00071 see when the ventilation grille level from the funnel

00072 area is relocated. So there are no background

00073 more cuts, which, for example, cross slide

00074 required. This is even optimized

00075 technically favorable measure by a centric

00076 to the connecting tube axis arranged receptacle for the

00077 locking pin of a cover cap that a downward

Has 00078 te wall, which parallel to the wall of the

00079 collar runs. To this extent, the cover cap is

00080 demoldable. It is also proposed that the

00081 bars of the ventilation grille in the shorter ellipse

00082 axis run. The longer ones over this material bridge

To connect wall sections of the ellipse leads to

An extremely stable design of the cover cap

00085 bearing ventilation grille level of the collar. Advantageous

It is 00086 when the plug-in receptacle between the grid

00087 rods of the ventilation grille sits. That way

00088 another material bridge between these ventilation grille

00089 rods formed. These elements can also be used

Assign 00090 technically so that an undercut

00091 smooth transition between the front edge of the ventilation

00092 connecting tube and the inner wall of the collar is present.

00093 It also proves to be advantageous for the cover cap

00094 in addition to the central locking pin support finger

00095 of different lengths that are on the upper forehead

Support the edge of the collar. The cover cap can be one

00097 incline position approximately according to the roof pitch

00098 men. The support fingers are useful around the central

00099 grouped locking pins; one grows from this

00100 balanced support. It is also proposed that

00101 the upper front edge of the collar in the direction of the roof pitch

00102 is cut obliquely. This yields one

00103 effective rotation lock the expediently the elliptical

00104 plan of the collar adapted cap. It requires

00105 none protruding the support fingers on the support side 00106 jumps. The invention further proposes that

00107 the cross section of the support fingers has a flat shape and

00108 this is at an acute angle to the course of the front edge of the collar

00109 lies. The latter produces a larger area

00110 cross-section as the shortest way the front edge

00111 crossing support fingers. There is also another

00112 advantageous embodiment through an index lead

00113 on the jacket wall of the ventilation connection pipe, which

00114 an index opening is assigned to the cathedral, in which the

00115 Index lead to fit the assembly end position of the

00116 ventilation connection pipe enters. That way

00117 ensures that only one another is technically

00118 agreed parts to be assembled on the building, which is also in

00119 is important with regard to product liability. Except-

00120 which is also proposed that the collar and the

00121 overlap to the jacket wall of the collar on the ridge side on

00122 is largest. This results in an effective baffle for

00123 running water. The assignment individual is optimized

00124 lization of the main parts forming the roof vent,

00125 if it is done so that the index lead as

00126 beyond the dimension of a wall thickness of the dome

00127 wall protuberance is formed and the

00128 index opening as a form-fitting holder on the cap

00129 pe. One the corresponding "keyhole", i.e. opening

00130 take, not having cap can not operational

00131 right, i.e. be fed up on the cathedral

00132 unless you remove the index lead. This

00133 would have created a leak

00134 gap results. The formation of a protuberance is

00135 easy to manufacture and without much effort

00136 realizable. So it is also an advantage if the

00137 would take the form of a wall protrusion of the cap

00138 is. The corresponding wall protrusion of the cap

00139 follows the outer contour of the wall protuberance of the

00140 mes. Especially with roofing slabs with inclined 00141 adjustable roof vent it proves to be advantageous

00142 liable that the index projection and the index opening as in

00143 of the roof pitch direction, over the whole

00144 back of the cathedral or the height of the cap going ribs

00145 are designed. It also turns out to be cheap if

00146 the ribs are undercut. So it comes to one

00147 good cohesion of dome and cap. The undercut

Flank 00148 should be selected so that it is practically possible to clip both parts together. Closing

00150 there is still a suggestion that the

00151 undercut is formed by a K-profile. The outward

00152 the grip takes place in the back of the divergent K-legs

00153 kel, in the space between the K-web. Finally

00154 it proves to be favorable that the index opening in

00155 area of a groove near the cap edge a over target

00156 break line held striker is assigned. So

00157 the cap can also be used on such roof ventilators

00158 find that have no index lead. The closing

00159 pieces blocks the index opening, so that e.g. an ancillary

00160 flow is avoided. 00161

00220

00221 The roof vent D is designed as a low vent

00222 assignable to a roof covering plate 1 (roof tile).

00223 The latter has an essentially rectangular plan

00224 on. It is the shape or the type of it

00225 surrounding covering panels of the roof skin accordingly

00226 designed. 00227

00228 From the profiled also in the manner of roof tiles

00229 roofing plate 1 goes an upward-facing dome 2

00230. The roof covering plate 1 is the same

00231 shapes and extends in the central area of the same. He

00232 (2) is also the roof

00233 kungsplatte 1 formed longer than its width

00234 carries. The height of the dome 2 is greater than that

00235 width and less than the length of the cathedral. It deals

00236 is a double-curved projection, the im

00237 essentially parallel parts of the cathedral 2

00238 in the foot or base area of the same flat, vertical

00239 form kale side walls 3, which in the upper area

00240 tapered. In the longitudinal direction there is a

00241 radius curve greater curvature than in the transverse direction

00242 tung. The one that determines the curvature of the longitudinal curvature

00243 radius R is based approximately at the intersection of the diagonals of the

00244 Basic rectangular roofing tile. This radius 00245 point is marked with x and lies approximately at the level of

00246 underside of 1. The radius point of the transverse arch carries

00247 the reference symbol x '. The transition of the side walls 3 in

00248 the transverse curvature also lies on a circular

00249 gen curved path B around the radius point x. The radius

00250 point x 'outgoing radius R' is approximately half the length

00251 of the radius' R. 00252 starting from the radius point x

00253 As can be seen in FIGS. 1 and 10, the apex

00254 empire of the cathedral 2 cut open. He describes an im

00255 essential oval slot 4. That from the start

00256 the inclination adjustability of a penetrating

00257 ventilation connection pipe 5 parked slot 4 is from

00258 Overlay material of roof vent D to close.

00259 It is a cap 6. The latter is the

00260 Ventilation connection pipe 5 molded on the same. The cap 6

00261 takes at least one of the outer surfaces of the

00262 Domes 2 correspondingly adapted shape, supports

00263 so full and sealing in the crown area of the cathedral

00264 2 from. The course corresponding to the contour is partially

00265 the figures 1 and 10. 00266

00267 Although the elongated hole 4 has the required

00268 before width for a tilt adjustment of the ventilation connection

00269 has tube 5, is with respect to FIG

00270 tipping shift by formation of appropriate locking

00271 tel waived. 00272

00273 The cap 6 sitting on the dome 2 then goes

00274 to an upper oval, approximately the contour of the elongated hole 4

00275 corresponding or elliptical connecting edge 7 in one

00276 essentially vertical collar 8 over. That brings

00277 a chimney-shaped cantilever that practically otherwise

00278 the coupling of the cap 6 forming the ventilation level,

00279 in which a ventilation grille 9 is formed. 00280 The ventilation grille 9 here consists of two central

00281 rich of the roof vent D crossing bars 10.

00282 These are placed just below the upper edge of the forehead 11

00283 of the cross-sectionally elliptical collar 8. It is in

00284 Cross-section of rectangular bars with the longer one

00285 face down. As can be seen in FIG. 3,

00286 ken the bars 10 of the ventilation grille 9 in

00287 area of the shorter elliptical axis of the collar 8. Sie

00288 connect the longer, flatter curved sections

00289 te a of the collar 8 and thus convey a high inner

00290 stability. 00291

00292 Because it also has an undercut-free transition

00293 between an upper end edge 12 of the ventilation connection

00294 take tube 5 and the inner wall of the collar 8,

00295 is a cross slide free demoldability. In the

00296 shorter elliptical axis of the collar 8 run namely

00297 the respective inner part of the collar 8 and the cylindrical

00298 see ventilation connection pipe 5 completely level. The

00299 can be clearly seen from FIGS. 1 and 10. 00300

00301 The upper end edge 12 of the ventilation connection pipe 5

00302 sets in via an upwardly opening funnel T in

00303 the inner wall of the collar 8; its (T) edge is rooted

00304 in it. In this way, in the longer ellipse axis,

00305 send, two crescent-shaped sliding surfaces 13 and 14. This

00306 collar clearly above the circular cross section of the

00307 ventilation connection pipe 5 and go from their maximum

00308 most extreme point in the manner of a penetration line

00309 back to the height of the upper front edge 12. The-

00310 this wedge area runs in the area of the shorter

00311 ellipse axis to zero (compare FIGS. 1 and 10),

00312 so that there is the same level of the inner surface of the

00313 ventilation connection pipe 5 and inner wall of the collar 8

00314 becomes recognizable. The pitch angle of the two sliding surfaces 00315 chen 13.14 is 30, measured to a horizontal

00316 len. 00317

00318 The sliding surfaces 13, 14 conduct with the ventilation

00319 grid 9, for example, rain in the ventilation

00320 end pipe 5. In return, for the rising

00321 the steam etc. a relaxation zone with the effect

00322 increased ventilation efficiency. The tube 5 ends in

00323 a kind of bowl. 00324

00325 The upward collar 8 is on its top

00326 cut at an angle. The bevel cut is 15

00327 a horontontal. The front edge 11 takes in the direction

00328 of the ridge a greater height to the elliptical edge of the hole

00329 15 of the collar 8 as the eaves side. The relationship

00330 is about 7: 1. There is almost a parallel

00331 lity to the slope of the roofing slab

00332 (see Figures 1 and 10). 00333

00334 Starting from the upper edge of the hole 15, the collar 8 sits down

Say 00335 as a section of equal height in the attachment point

00336 connecting edge 7 of the cap 6 continues. The amount of this

00337 section corresponds approximately to the height of the ridge side

00338 section of the collar 8. In this respect, the funnel T

00339 about halfway up the collar, but that

00340 funnel-side end through the bevel cut of the forehead

00341 edge 11 increasingly wedges. In the direction of the flowing water

00342 there is a sequence with regard to the collar 8

00343 significant cant that the floating of flowing

00344 avoids water. Rather, it brings closer

00345 curved section b of the elliptical wall

00346 fertilizer of the collar 8 a kind of flow divider for the

00347 case that the running water should go higher than that

00348 there, ie ridge-side, lower-drawn cap 6. 00349 00350 The cap 6 is even strikingly deeper on the ridge side.

00351 gen. Your first-sided edge portion 16 is except for the

00352 bottom of a recess 17 of the roofing plate

00353 extended. On the bottom of the recess 17 is supported

00354 the edge section 16. Swiveling the cap 6

00355 and thus the ventilation connection pipe 5 about the axis x

00356 is therefore not possible on the ridge side. In the opposite direction

00357 there is also a tilting of the same under

00358 binding support. The latter is that the

00359 edge edge section of the elongated hole 4 on the eaves side

00360 in the throat between the underside of the sliding surface 14

00361 and the jacket wall of the ventilation connection pipe 5

00362 supports. 00363

00364 The third support that prevents tipping

00365 point of the three-point bond created in this way is from

00366 a bar 18 formed. The pairs on the coat

00367 wall of the ventilation connection pipe 5, in the area

00368 of the horizontal axis labeled x. Said

00369 strips 18 extend in the diametral of the tube

00370 5, in the plane of the shorter axis of the ellipse.

00371 You sit in one of the storage trough 19 of the parallel

00372 side walls 3 of the dome 2. Figure 4 illustrates an am

00373 lower end of the bar 19 realized bevel

00374 20 which is the receiving hole of the roof covering plate

00375 slightly widened during clip assembly, i.e. so the side

00376 walls 3 of the cathedral 2 spreads slightly, which then, under

00377 the effect of the restoring force of the material again

00378 approach each other until they touch the jacket wall of the ventilation

00379 tangent end tube 5 again. 00380

00381 To ensure that only type-matched roof ventilation

00382 ter D assigned to the corresponding roofing plate 1

00383 net is a kind of tamper-evident

00384 adorns. The latter results from an index lead 21 00385 on the jacket wall of the ventilation connection pipe 5, which

00386 index projection 21 assigned an index opening 22 on the dome 2

00387 net. The index protrudes into this index opening 22.

00388 jump 21 to fit in the final assembly position of the ventilation

00389 tungsansehlußrohres 5 a. If you use a roof

00390 kungsplatte, which does not have the index opening 22, so

00391 is not supported and therefore not sealing

00392 support of the cap 6 against the top of the dome 2

00393 ben. 00394

00395 The opening Ö of the chimney-like collar 8

00396 views a precaution for assigning a cover

00397 cap 23. This provision exists on the roof vent side

00398 in a center to the ventilation connection pipe axis y-y

00399 arranged receptacle 24. In this can be

00400 insert a locking pin 25 above. It starts from the

00401 inside of the ceiling 26 of the cap 23. The

00402 locking pin 25 is also molded as a hollow pin

00403 and runs parallel to a downward man-

00404 telwand 27 of the cap 23. The jacket wall 27 surrounds

00405 in an overlapping assignment the collar 8, with

00406 good ventilation, i.e. as possible pressure loss

00407 me flow bringing radial and vertical section

00408 to the collar wall. Figures 1 and 10 make it clear

00409 that the collar 8 and the overlap to the outer wall of the

00410 collar are largest on the ridge side. The first-sided

00411 end of the jacket wall 27 of the cap 23 forms one

00412 effective splash water baffle. 00413

00414 The parallel rectification of the central locking pin

00415 fen 25 and the jacket wall 27 enables a cross slide

00416 free demolding. Cover cap 23. The cover 26 of the cover

00417 cap 23 is in the descending direction of the ridge / eaves

00418 as well as slightly convex seen in parallel from above

00419 arched. The ceiling 26 runs in its basic orientation 00420 at an acute angle to a horizontal. This angle is

00421 at approx. 10 ° to the horizontal. 00422

00423 The plug-in active points to the captive assignment

00424 section of the locking pin 25 a cross recess.

00425 This creates four locking hooks 28 with outward

00426 directional locking lug 29. It engages under the lower one

00427 front edge of a sleeve 30 forming the plug receptacle 24.

00428 The sleeve 30 is between the pair and parallel

00429 running bars 10 lying, molded onto this.

00430 So it essentially forms one in the center

00431 longer ellipse axis oriented, approximately double

00432 gene-shaped material bridge between the two bars

00433 10. 00434

00435 In addition to the central locking pin 25, the cover

00436 cap 23 four support fingers 31 formed. Hold the latter

00437 the cap 23 at a vertical distance from the front edge

00438 11 of the collar 8. They leaned on this edge of the forehead

00439 11 from. It is about the support fingers

00440 free-standing formations below the ceiling 26. How

00441 Figure 5 illustrates, there is a sufficient edge distance

00442, which is preferably the same all around

00443 spaced vent gap 32 leaves. The cross

00444 cut the support finger 31 is long rectangular. The

00445 corresponding flat shape emerges from the above figure 00446. The support fingers 31 are in the narrower curvature

00447 areas of the also elliptical in outline

00448 cover cap 23 realized. They point with their longer ones

00449 Extension edge in the direction of the central locking pin

00450 25. As a result, they lie at an acute angle to the course of the

00451 front edge 11 of the collar 8. So there is a flat

00452 larger support cross section than a strictly

00453 transverse alignment to the front edge 11. 00454 00455 Towards the free ends there is an easy demolding

00456 tapering the support fingers 31 before. 00457

00458 As can be seen from FIGS. 1, 6 and 10, these are

00459 support fingers 31 of different lengths. The first-side

00460 gen are shorter, the eaves side of about double

00461 length. This brings the closeness of the ridge closer

00462 upper front edge 11 to the ceiling 26. For example,

00463 splashing water is not easily in the

00464 position to get into the opening Ö. On the other hand

00465 almost twice the distance between the

00466 gen area of the front edge 11 and the ceiling 26 before.

00467 Any splash water reaching the ceiling 26 or

00468 consensus flows according to the concave seen from the inside

00469 curvature of the ceiling 26 in the area of the inside of the

00470 jacket wall 27 of the cap 23. It is far there

00471 spaced away from the collar 8. 00472

00473 Overall, there is a ventilation-optimized roof vent

00474 D, which is also easy to spray and cross

00475 can be generated without a slide, even with a

00476 intersection-free transition from ventilation connection pipe 5

00477 and inner wall of the collar 8, with additionally in the rear

00478 view of the water drainage an advantageously usable

00479 supernatant is present. 00480

00481 The lower edge 6 'of the cap 6 has a protective helical shape.

00482 wanders, favored by the corresponding neck

00483 ge first-side lowering of its edge

00484 Section 16. Such a curly, practically space-saving

00485 allel-extending lower edge also shows the hole overlay

00486 covering cap 23, i.e. the lower front edge 27 '

00487 of her jacket wall 27. 00488 00489 By the curvature of the relatively thin-walled ceiling 26 of the

00490 cover cap 23 can be a little shorter

00491 25 pin a tensioning element lying in the ceiling vault

00492 kung can be used. The pulls the support fingers 31 against

00493 the front edge 11. Oblique course of the front end 11

00494 and / or different length of the supporting fingers 31 ma

00495 Chen any special rotation lock of the cover cap 23rd

00496 unnecessary compared to the collar 8. It results. 00497

00498 The gap distance can go to zero on the ridge side. 00499

00500 Further training in tamper-evident

00501 hand of Figures 10 to 18 are explained. The reference

00502 digits are, sometimes without repeated text,

00503 applied accordingly. The index lead 21 is now

00504 no longer on the jacket wall of the ventilation connection pipe

00505 5, but at the cathedral 2. Specifically, the procedure was

00506 that the index projection 21 as a wall protrusion of the

00507 Domes 2 is realized. The corresponding protuberance

00508 goes beyond the dimension of the wall thickness shown

00509 Domes 2 beyond. 00510

00511 The matching index opening 22 is the inside of the

00512 molded cap 6. The index opening 22 as a form fit

00513 en receptacle for the index projection 21 on the cap 6

00514 generated in the form of a wall protuberance. 00515

00516 Both the index projection 21 and the index opening

00517 22 are designed in the form of ribs. The index index

00518 jump 21 forming rib extends in roof pitch

00519 direction in the plane E-E (Fig. 13), namely

00520 lying on the eaves side. It goes all over the back of the

00521 Domes 2, that is, starting at the edge of slot 4 and

00522 ending at the foot of the cathedral 2, formed from the top

00523 of the covering plate 1. The corresponding individual 00524 agent works in this way even with a

00525 adjustable roof vent, because the ribs in the nei-

00526 direction of the cap 6 tiltable by x and the corresponding

00527 tilting ventilation connection pipe 5. 00528

00529 On the ridge side a similar individualization

00530 means can be provided. 00531

00532 If one is now not exactly matched to the construction principle

00533 assigned cap, which means no or no suitable

00534 has index opening 22, so there is a well supported

00535 and tight cap position towards cathedral 2 only if the index

00536 projection 21 disappears. According to a corresponding

00537 Detaching the index tab 21 would be a foreign cap

00538 6 can be assigned. Such manipulation

00539, however, brings a breakthrough that

00540 chung 34, as it results from Figure 15. That takes

00541 the Dom 2 the otherwise high shape due to its shape. Self

00542 if only the area covered by a foreign cap 6

00543 of the index projection 21 would be cut away, so would

00544 a gap Sp remains at the lower edge of the cap 6

00545 ben. This gap Sp can wobble on the ventilation

00546 also enlarge connection pipe 5. In any case, one

00547 such cap assignment does not meet the requirements of a specialist

00548 male assignment. 00549

00550 In the same way extends over the entire height of the

00551 cap 6 the corresponding index opening 22, namely the

00552 following the dome curvature. 00553

00554 On the other hand, if there is a roof covering plate, which

00555 not the comb or rib-like index index

00556 jump, but on the other hand an index opening 22nd

00557 of the type described is realized on the cap, so

00558 lies due to the wall protrusion 00559 Channel only a tunnel-like path between the outside

00560 of roof vent D and the jacket wall of the ventilation

00561 end tube 5 before. However, this path can be closed

00562 can be kept, as can be seen from Figure 12. There

00563 is the index opening 22 in the area of a near the cap edge

00564 slot mouth 35 held shut by a striker 36.

00565 As required, this can also be molded on

00566 Slightly loosen striker 36. It is about one

00567 predetermined breaking line 37 held at or in the index opening 22

00568 ten. Such a predetermined breaking line is indicated by clear

00569 cross-section reduction of the material achieved so that

00570, for example, only a cuticle as a connecting bridge

00571 for the wall extension forming the groove-like index opening 22

00572 slip remains. 00573

00574 While with respect to the variant according to FIG. 14 the index

00575 projection 21 and the index opening 22, i.e. their respective

00576 in the same direction wall protrusion or ribs in

00577 cross-section are designed essentially trapezoidal

00578 with the base facing the inside of the dome, are the corresponding

00579 undercutting ribs according to Figures 16 and 18.

00580 The undercut flanks of the index projection 21

00581 are designated 21 'and the undercut flanks

00582 of the wall protuberance forming the index opening 22

00583 with 22 '. This is the basis of the trapezoidal

00584 cross-section but the cathedral 2

00585 turns. 00586

00587 According to variant FIG. 17, there is a roof-shaped respect

00588 ve triangular wall protuberance with regard to the index

00589 projection 21 and the index opening 22. It deals

00590 is practically an equilateral triangle, the

00591 one side is flush with the wall of the dome 2. 00592 00593 The variant according to FIG. 18 is based on the same basic

00594 principle like that of Figure 17, except that the triangular

00595 tip a strip-like, which forms the index projection 21

00596 tiger bridge 38 attaches, from the dome-side transverse center

00597 the roof-shaped profile 39,

00598 which towards the dome 2 including an angle of

00599 diverge approx. 90 °. Place webs 38 and legs 39

00600 represents a clear K profile, with the free ends of the

00601 Leg into the shape of the dome 2. The K-typi-

00602 see gusset spaces 40 form locking recesses for locking

00603 projections 41 on the edge of the groove-shaped index opening 22.

00604 The locking projections are emphasized on the free

00605 ends of the web 38 can be pressed. In certain cases

00606 but also end-face threading of the components 2

00607 and 6 grab. 00608

00609 The K can be recognized as a symbol of an indication of origin

00610 as an initial for "Klöber". 00611

00612 on the cap 6 only require the locking hooks 28 and

00613 ventilation connection pipe 5 of the roof vent D sliding element

00614 moments. The other article contours of the roof vent

00615 D are designed so that no slides, i.e. Cross

00616 are required. 00617
