Abstract

A roof air-vent pipe (D) has a projecting dome (9) on the top side of a metallic roof-covering plate (1) and a vent pipe (7) carried by the dome over a cap (19). In order to obain a roof ventilator which is particularly efficient in use, the plastic dome which carries a plastic vent pipe (7) is set on the marginal area (8) of a hole (2) cut out in a roof-covering plate (1).

Description

00001 roof vent

00002

00003 The invention relates to roof ventilators with over

00004 the top of a metal roofing sheet

00005 protruding dome and carried by this over a cap

00006 a ventilation pipe. 00007

00008 roof vent of this type are, for example, by the

00009 DE-PS 260 915 and 284 185 known. In the latter scripture

00010 is expressly on sheet metal as a manufacturing material

00011 pointed out in general in the other reference

00012 a solderability. 00013

00014 roof vent, even the tilt adjustable type, whole

00015 made of plastic, especially hard PVC, is

00016 through prospectus KLÖBER, edition 1970, (Studio booth K 202

00017 70), also by DE-Gm 82 27 425. Last

Lere literature reference shows the connection of a

00019 flexible PVC hose reaching under the roof skin

00020 the end of the ventilation pipe. 00021

00022 In roof skins consisting of sheet metal, in particular copper

00023 remote roofing, make metal roof vent

00024 represents a significant cold or heat bridge. The high one

00025 temperature range undergoing changes affects in

00026 generally disadvantageous on the subsequent hose line

00027 tung from; the aging capacity of the junction of the

00028 hose line is significantly affected, quite

00029 apart from the exchange effect of such metal

00030 roof vent on it. The seal security at

00031 hose is lost; in the worst case, the

00032 hose even slip off. 00033

Knowing these disadvantages, the present has

00035 invention set the task of a roof vent 00036 create a greater security in the connection

00037 for connection on the housing side, especially downpipe

00038 concludes. 00039

00040 This problem is solved by the in claim 1

Bene invention. 00042

The subclaims are advantageous developments of the

00044 roof vent according to the invention.

00045

According to such an embodiment is a generic

00047 roof vent high allocation security achieved. In

00048 with regard to the metal roof covering results in a

00049 optically trouble-free continuation even in the implementation

00050 area; the roof covering plate fits stylishly

00051 a. In addition to this optical side is at the same time

00052 solved the temperature related problem. The metals too

00053 own high conductivity no longer settles in

00054 continue the connection of the line or the hose. Con-

To do this, 00055 kret is such that the plastic

00056 existing and a plastic ventilation pipe storage dome

00057 to the edge area of a in a roofing slab

00058 incised hole is attached. With such a

00059 Chen Dom is the more advantageous, modern connection technology

00060 takeover, be it with regard to the so-called Nei-

00061 adjustment of the ventilation pipe, the tightness

00062 or be it the much cheaper cost of ownership

00063 most. The attachment also brings a resilient

00064 transitional area between the two different

00065 materials. The stability is significantly increased

00066 sets. In adaptation to the existing or through

00067 Weathering staining of the roofing slab

00068, the cathedral etc. can also be colored accordingly.

00069 A not only durable, but also dense 00070 assignment between the dome and roofing slab results 00071 by spraying the cathedral. That doesn't require any

00072 special processing of the incised hole. The

00073 appropriately dispensable finish also has an effect

00074 on the cost-effective training of the roof vent

00075. Specifically, the attachment point continues to look like this

00076 the cathedral with an outward facing collar with a

00077 fork opening takes up the edge area. The corresponding

00078 circumferential attachment appearing in cross section as a fork

00079 position is created by overlapping and undergripping the edge

00080 realm of the incised hole. This is optimized

00081 achieved definition in that the edge area holes

00082, which extends from between the forks

00083 bridges are penetrated. Such a marginal perfo-

00084 ration on the one hand does not weaken the marginal

00085 of the covering plate and prevents other

00086 a gaping of the fork tines, especially with large

00087 overlap length. The tilt angle already indicated

00088 adjustability of the ventilation pipe can be pointed

Technically simply take into account right away, namely

00090 in that at the level of the edge or the edge area

00091 des Domes storage bags for hinge pins of the ventilation

00092 tubes are molded into the plastic. Such storage

00093 see are open to the roof and allow that from

00094 below insertion of the hinge pin under

00095 composition of the hinge point. With a pure one

00096 copper roofing is an advantageous approximation of

00097 domes etc. to the copper roofing

00098 te made possible by a powdery copper portion

00099 as interference in the plastic molding compound of the cathedral.

00100 The copper portion is also superficially exposed

00101 This means weatherability with the advantage of

00102 Formation of precious rust, i.e. verdigris. The exposed

00103 Dom receives a roofing corresponding

00104 appearance. Moreover, it is finally from

00105 advantage that the ventilation pipe and the cap a 00106 powder and / or platelike copper interference

00107 have, so that the said effect also on this

00108 extends. Such metallic admixtures have

00109 equal the advantage that, for example, from darker

00110 plastic existing parts of the roof vent no such

00111 bring large heat so that these parts

Do not discard 00112 either. The attachment point is optimized

00113 between the cathedral and the edge area in that the cathedral

00114 an upward bend of the edge of the hole is molded.

00115 The edge of the hole thus forms a highly stable

00116 standing collar. This also increases the area

00117 Stability of the roofing sheet itself. Also

00118 does not form this stand-up collar from the running water

00119 overflow dam, so that even if damaged

00120 of the attached dome collar no water can penetrate.

00121 A further characteristic consists in ^'dεß the holes

00122 in the upturned hole edge from the circular shape

00123 are distorted. If the condition is not yet folded, U0124 is perpendicular to the plane of the roof covering

00125 flat drill access. The next one

00126 Edging of the edge resulting distortion of the holes

00127 elongated holes brings a widened hole edge support

00128 for the bridges connecting the fork tines. Self

00129 certain traces of deformation do not require a finish. she

00130 are visible from the fork-shaped edge of the cathedral

00131 withdrawn covered. An advantageous training for

00132 Creation of stable storage pockets then consists in

00133 that the upwardly bent edge of the hole in the area of

00134 storage bags exposed to the inside and with this

00135 exposed area sliding surfaces for inserting the

00136 forms the hinge pin of the ventilation pipe. The bags

00137 are at least partially lined with metal?

00138 especially the entrance area of the storage pockets

00139 a stabilization simply generated using the upward-bent 00140 hole edge. The storage bags 00141 can even be bent over the front edge of the

00142 teten edge of the hole. With the usual vertical

00143 length of the hinge pins there is still a

00144 rich against the metallic section of the storage pocket

00145. Finally, there is a suggestion that on the outside of the storage pockets there is a double offset of the 00147 lateral surface of the cathedral, on the one hand that of the

00148 disengagement of the wall to create the storage pocket and

00149 on the other hand due to the metallic reinforcement

00150 the folded up. Hole edge. 00151

Cie be¬ 00205 is made of metal, preferably copper. The corresponding 00206 copper sheet is angled upwards at its 00207, that is, the sloping edge edges running in the roof slope. 00208 The angle leg has the reference number 2. 00209 00210 An upward angled leg 3

00211 also shows the neighboring, usual roof

00212 kungsplatte 4 on. It also consists of copper sheet. 00213

00218 kel 2, 3, directed downwards. 00219

00220 Instead of a separate cover strip 5 there is of course

00221 also the possibility of using the angle leg 2 as a cover

00222 ste 5 continue to run in such a U-shaped extension

00223 so that in this way the neighboring angular

00224 leg 3 is also overlapped sealingly (cf.

00236 The roof vent D is the top of the

00237 metal roofing sheet 1 outstanding ventilation

00238 tube 7 equipped. Said ventilation pipe 7 is exposed

00239 two parts together, namely an upper tube part ^~ '

00240 and a lower pipe part 7 ^'' - both parts are

00241 screwed together. This screw connection is counter

00247 That with its lower tube part 7 '' inside

00248 of the roof space reaching ventilation pipe 7 penetrates

00249 cut into the roofing sheet 1, in

00250 essential oval hole L. Taking into account the

00251 aspired adjustment of the ventilation pipe 7 to

00252 Allow vertical alignment of the same

00253 despite different angles of inclination in practice

00254 roof surfaces are in relation to the hole L.

00255 an elongated hole with greater length in the inclination plane. 00256

00257 A dome 9 extends from the edge region 8 of the hole L. The

00258 Dom 9 there has an upward going

00259 dome-shaped curvature. The curve line runs in the

00260 Inclination direction of the roofing plate 1 seen to

00261 a radius point P. The radius point P is small

00262 Distance above the top of the roof covering plate

00263 1, intersects the longitudinal central axis x-x of the ventilation pipe

00264 7 and forms a fulcrum. 00265

00266 The dome 9 is made of plastic, especially hard PVC.

00267 He is molded on the covering plate 1. The corresponding

00268 appropriate injection bead goes clearly from the sectional view

00269 position shown in Figure 2 and 6 respectively. It emulates one

00270 outward collar 10. The extrusion material

00271 is on the top and bottom of the roof covering plate 1

00272 equally distributed in thickness. The collar 10 forms so

00273 table one at the foot of the cathedral? uninterrupted circulation

00274 fende fork opening 11 which receives the edge region 8

00275 and seals. The bottom of the fork closes

00276 ßend against the inward edge of the edge

00277 reichs 8. Such "embedding" makes it unnecessary

00278 to give the edge area a special finish. Given 00279 if necessary, an adhesion promoter for the spraying process

00280 added. 00281

00282 To optimize the desired • injection molding

00283 fertilizer of the dome 9, the edge area 8 is broken. It

00284 is a perforation, which is nearby

00285 extends the edge of the edge area. In the execution

00286 example, this is achieved through holes 12. The perforated

00287 he is particularly clear from Figure 5. 00288

00289 Over such holes 12 bridges 13 arise, so that

00290 material of the socket to be designated as fork tines 14

00291 lip is in a homogeneous composite. The lips respectively

00292 Forks 14 cannot gap. You are under

00293 Crossing the fork opening 11 anchored to each other. 00294

00295 At the level of the edge of hole L, i.e. the edge

00296 reichs 8, the dome 9 bearing pockets 15 are formed. she

00297 are open towards the attic and take each

00298 a hinge pin 16. Such hinge pins

00299 go on αiametrically opposite sides,

00300, namely in a common cross-sectional plane,

00301 from the jacket wall of the ventilation pipe 7. they are

00302 molded. 00303

00304 The ventilation pipe 7 is also made of plastic, preferably

00305 white hard PVC. 00306

00307 With regard to the hinge pin 16 it is

00308 around the longitudinal axis of the pipe,

00309 circular convex rounded strips. The top end

00310 is supported on the ceiling 17 of the storage pocket 15

00311 1 it can be seen that the flanks of the pocket are

00312 diverge so that the pivoting requirement of the ventilation 00313 tube 7 taken into account for the inclination adjustment

00314 is. 00315

00316 extends in the center of the top curve of the end

00317 the radius point P. 00318

00319 Although the Dom 9 could be semi-spherical,

00320 it is spatially parallel to the longitudinal edges of the

00321 roofing plate 1 retracted, essentially

00322 up to the dimension of the outside diameter of the ventilation pipe

00323 7, so that two domes forming an elongated shaft

00324 ten walls 18 on the outer wall of the cross section

00325 nestle circular ventilation pipe 7. The so created

00326 fene elongated shaft goes in on the eaves and ridge sides

00327 a narrower, preferably the pipe cross-section curvature

00328 adapted contour over. 00329

00330 The dome-shaped top of the dome 9 is overlapped

00331 from a ventilation pipe 7 also penetrated

00332 hood part in the form of a cap 19. Based on the latter

00333 the ventilation pipe 7 from. At least the one on the top

00334 side of the dome 9 guided inside of the

00335 cap 19 is designed to fit the shape. The cap can be

00336 guided in the inclination plane, practically

00337 and thus the angle of inclination of the ventilation

00338 pipe 7 to the roofing slab level

00339, according to the length of the long

00340 hole L or the extent of the above

00341 written shaft in the ceiling of the cathedral 9- 00342

00343 The ridge side is the level of the roofing slab 1 in

00344 moved in the direction of the roof space. The corresponding

00345 Confiscation has the reference number 20. It is al?

00346 channel around the correspondingly lowered foot of the

00347 Domes 9. The said gutter circumscribing the foot 00348 leaves the adjustment-related immersion of the cap 19 with 00349 its cap edge 21 there. The dome 9, respectively

00350 section of the cathedral side walls 18, and the subsequent

00351 eats the transverse rounding of the end of the dome there

00352 directly in the peripheral injection bead or collar

00353 10 over, but only after the formation of the

00354 gutter-like confiscation 20. By confiscation 20

00355 also creates a certain polydirectionality of

00356 wall sections, resulting in an extremely effective

00357 stiffening of the first half of the cathedral contributes

00358 and also the connection to the roof covering

00359 plate stabilized even further. 00360

00361 The two pipe parts 7 ', 7' 'are, as already indicated,

00362 screwed together. The relevant coupling

00363 position has the reference character K. It is short

00364 above the collar 19, which is still upwards

00365 continues in a cuff 22. At the end face 23

00366 supports a horizontally circumferential shoulder 24 of one

00367 federal 25 of the upper tube part 7 '. The latter (25) is

00368 integrally formed on the jacket wall of the upper tube part 7 '. On-

00369 offset to the front closes an external thread

00370 section 26 of the upper pipe part 7 ', which outer

00371 winch section 26 with a suitable internal thread section

00372 cut 27 of the lower pipe part 7 '' interacts. The

00373 usable thread engagement length is shorter than the supporting

00374 active projection of the end face 23, so that over the

00375 coupling point K in connection with the support of the coulter

00376 kidney pin 16 on the ceiling 17 of the fork tines 14 a

00377 adjusting and locking device is present, that is the

00378 set orientation of the ventilation pipe ^~ ruiπ Dom

00379 releasably fixed. 00380

00381 Around the dome of the roof covering plate 1

00382 9 to give the same appearance in color, contains 00383 the molding compound forming the dome is an interference of a

00384 powdered copper portion. This conveys

00385 borrowed the typical copper red color and does the rest

00386 also the formation of rust. Both parts take with the

00387 Color a verdigris-like color. In Figure 7 is a

00388 wall section of the dome 9, more precisely its side walls

00389 de 18. The interference results from one

00390 point-like entry. They embody the copper part

00391 28, which can be weathered not only from the outer surface 29

00392 protrudes, but also further down

00393 is embedded homogeneously distributed. Preferably, the

00394 entire cross section with copper portion 28 added, like

00395 that its symbolic dots

00396 tung finds. 00397

00398 The gradual breakdown of the binder of the wall-forming

00399 plastic molding compound gradually sets at the same time

00400 always releases the powdery copper particles. The

00401 has a long service life. 00402

00403 The weathering of the same color is not

00404 limited to the cathedral 9 alone, but also for the

00405 other parts created by spraying,

00406 so that the ventilation pipe 7 and the cap 19

00407 finally cuff 22 a powder and / or platelet

Have or contain 00408 mige copper interference. 00409

00410 The copper content 28 is between 5 and 30%. The plat

00411 size is about 50 my, that of the copper powder

00412 at 1 to 5 My- 00413

00414 The injection of the cathedral appears self-explanatory,

00415 which is why a representation of the spraying device

00416 is pulling. 00417 00418 The dome 9 could also be attached by gluing. 00419

00420 Now what the roof vent D according to the second

00421 example (Fig. 8 to 11) relates, so here too

00422 the edge area 8 with the collar 10 of the dome 9

00423 technically connected, but with the structural sub-

00424 decided that the cathedral 9 is now on an upward bend of the

00425 hole edge is molded. The edge area 8 respectively

00426 hole edge itself is the upward bend.

00427 fern are used accordingly. The upward fold

00428 of the edge 8 of the hole is clearly shown in FIG. The

00429 corresponding fold line is called 30. It runs

00430 equally spaced from the edge to hole L and is as

00431 dash-dot line executed. The holes 12 extend

00432 is closer to the edge of the hole than to said

00433 line 30. They (12) are all drilled or punched perpendicular to plane 00434 of the roofing plate 1. In around

00435 90 ^" position on the outside of the roof runs the

00436 hole or punch axis then parallel to the 00437 plane of the roof covering plate.

00438

00439 Since the area of the edge of the hole that is folded upwards to the

00440 interior towards the longitudinal expansion in the oval

00441 exposed to the direction of rotation, the holes 12 in

00442 upward folded state of the edge area 8 a

00443 longitudinal distortion, i. H. which the explanatory

00444 th bridges 13 forming material sections can be found in

00445 the general direction of load of the dome 9 and thus

00446 connected components a widened support surface on

00447 hole edge in front. The hole L

00448 circumscribing edge has namely in folded up

00449 state of the edge area corresponding to the folding line 30

00450 edge length. The folding line 30 remains in the

00451 so-called neutral fiber, the edge of the hole has the

00452 maximum stretch length. Any resulting from the fold- 00453 en Factory traces disappear in the collar 10 of the spray

00454 niche assigned domes 9. No special one is required

00455 Reworking the edge area 8. 00456

00457 In the zone in which the storage

00458 see 15 is formed, the edge region 8 is hole-free

00459 held. The interruption of the practically equally spaced

00460 there were holes 12 in this zone is shown in FIG.

00461 loaned. In the zone forming the storage pocket 15 is also

00462 the inner fork tine 14 of the molded collar 11

00463 omitted, and this in terms of level so that the

00464 would be edged hole edge 8 in the area of its two

00465 bearing pockets 15 exposed to the inside of the bearing pockets 15 00466. The side of the bevel facing the hole L

00467 ten hole edge 8 forms sliding surfaces 31.

00468 see 15 are so partially lined and special

00469 friction and support stable with regard to insertion and

00470 bearing the hinge pin 16 of the ventilation pipe 7. Die

00471 Support takes place over the outward, i.e. from

00472 other pioneering faces of the vertically long oval

00473 hinge pin 16. The shaft entrance in particular is like this

00474 well armored. There is no take off or even

00475 a distortion of the collar 10 instead. The tightness is

00476 optimally achieved, especially since the perforated

00477 edge 8 as stand-up collar over the top of the roof

00478 kungsplatte 1 protrudes. Also im not used by the

00479 sliding surface 31 covered base of the storage pocket 15,

00480 more precisely in the blanket 17 closer to its ceiling

00481 cut, does not subject to mechanical stress

00482 insofar as the storage pockets 15 to overlap

00483 top end edge 32 of the upward folded

00484 hole edge 8 continues on the same level - 00485

00486 On the other hand, however, in the area of the hinge

Place 00487 between the dome 9 and the inclinable tube 7 00488 no material weakening or reduction of

00489 cathedral side walls 18, since the one forming the storage pocket 15

00490 area is formed by material offset, i.e.

00491 pung a side wall portion. That goes clearly

00492 borrowed from FIGS. 2 and 10. Thanks to the

00493 pung arises on the outside of the storage pockets 15 a two-

00494 times stepped offset of the lateral surface resp. 00495 ve side walls 18 of the dome 9. The first, overhead

00496 gradation is designated 33 and gives the outer contour

00497 the storage bag again, the second one below

00498 gradation 34 forms the part of the wall offset,

00499 which due to the thickness of the relatively thin sheet of the roof

00500 cover plate 31 is formed. This stage can

00501 also continue around the foot of the cathedral 9. 00502

00503 With regard to the color adjustment of the cathedral and

00504 of the tube here the means mentioned above. At the

00505 second embodiment is the adjustment range
