Abstract

The invention concerns a roofing panel (1) with a roof duct (D) in the form of a pipe (2) which extends from the underside of the roofing panel (1) to above the latter, the inclination of the duct (D) being adjustable. The invention is characterized in that the appropriately dimensioned passage hole (3) in the crown region of a dome (4) has a domed top, and a suitably shaped hood section (5) is associated with the pipe (2). The superimposition of the hood section (5) on the dome (4) is ensured in that the pipe (2) is linked to the roofing panel (1) in the region of the underside (10). The hood section (5) is displaceable on the pipe (2) and loaded by a threaded ring (12). In order to attain a structurally simple, easily fitted assembly, the threaded ring (12) takes the form of a nut through which the pipe (2) passes.

Description

00001 Roof covering plate with roof passage

00002

00003 The invention relates to a roof covering

00004 te with roof duct in the form of a

00005 te of the roofing sheet to above it

00006 reaching, inclinable tube in that

00007 the appropriately dimensioned passage hole in the apex

00013 see support of the pipe towards the roof covering plate 00014, and the hood part is displaceable on the pipe and is loaded by a screw ring. 00016

A roof covering plate of this type is through the

00018 DE-OS 36 43 319 known. It is a two-part

00019 structure of the tube. The two pipe parts are

00020 screwed together. The shortening that occurs

00021 pull is used to brace the stack of

00022 hood part and cathedral used. Here one enters through

00023 shoulder offset against the underlying

00024 end hood part. The upper tube part serves as a screw

00025 ring. The above-mentioned support takes place via the holding ribs defining the tilting joint of the pipe.

The object of the present invention is to achieve the

To get 00031 te plumb right alignment fully effective with simple means even with one-piece tube formation. 00033

00034 This problem is solved by the in claim 1

00035 bene invention. 00036 subsequent features give advantageous further

00037 educations. 00038

00039 As a result of such an embodiment,

00040 adhesive, structurally simple alignment and definition

Achieved a roof duct, be it in the form of a

00042 breather, an antenna tube or the like. The

00043 multi-part is to achieve a corresponding

00044 tension no longer required. The usual,

00045 can bring a shoulder wall offset on the tube

00046 omitted. To apply even higher clamping forces,

It turns out to be advantageous that the

00048 screw ring designed as a nut penetrated by the tube

Is 00049. The generally polygonal mother allowed

00050 also the attachment of a screwing aid. Will continue like this

Proceeded that the screw ring counter thread also in

00052 upper end portion of the tube is formed, can

00054 here the additives on which the respective application is based

Grasp 00055 on, for example by assigning a cap,

00056 a mesh basket, reducer or other construction

00057 parts. A good distribution of the clamping forces results

00058 when the load is directed towards an upward

00059 th collar of the hood part goes. There is also one

00060 design of even independent importance in

00061 that the screw ring from the top of the collar of the

Part of the hood is formed and, from the bottom of the

00063 screw ring starting, the hood wall elastic

00064 is designed evasively. As a result, the remains

00065 screw ring forming part rotatable, the elastic

00066 material of the hood wall which is out of round during rotation

00067 Area of the dome, which is generally flattened on the side

00068 follows. The corresponding elasticity also has that

00069 Advantage of a good, tight fit. The cap

00070 shape of the hood part favors the provision plus 00071 nestling of the softer material against the upper

00072 te of the cathedral. In order to simplify

00073 solutions using a

00074 en to get water tightness brings

00075 further developing the invention in proposal to seal a ring

To provide device between the collar end and pipe wall. So

00077 it is used despite the relocatability

00078 the ring joint between the pipe wall and the inside of the

00079 genendes excluded that water penetrates there. To achieve 00080 the desired 00081 tightness even with unfavorable tolerance pairings and to justify a long-term effect 00082 with simple means,

00083 hit that the collar in one of the screw ring loaded

00084 constant lip leaking out on the ring of the seal

00085 touches down under radially inward pressure. Except-

00086 the lip is in direct contact with

Avoided the ring seal, so that the screwing movement

00088 does not act as a frictional force on the ring and

00089 possibly dragged and messed with them. It is coming

Rather, a smooth rotation with according to the

00091 thread pitch increasing compression of the sealing body

00092 pers. In order to provide a preferred component in this regard, the constructional procedure was as follows: the lip

00094 at an acute angle obliquely upwards to the longitudinal axis of the pipe

00095 stands and the screw ring a suitably sloping

00096 has printing area. Finally it is suggested

00097 that the ring seal is designed as a sealing O-ring

00098 and lies in a casing wall groove of the tube. The

00099 seal O-ring thereby finds its secure

00100 right axial support. Add to that the ring seal

00101 acts as a clamping buffer, so that the support

00102 of the pipe to the roof covering plate not over

00103 charge goes beyond charges. 00104

00105 The object of the invention is shown below

00131 plate 1 is in the purpose of optically good adjustment

00132 surface image of a roof in its basic structure like that

00133 other roofing tiles (roof tiles) designed. 00134

00135 A pipe 2 used, for example, for ventilation

00136 crosses a through hole 3 of the roof covering plate

00137 1. The latter is in the apex area one for

00138 roof top domed 4. The passage

00139 sloch 3 is realized as an elongated hole. The longer one

00140 extension lies in the inclination direction of the roof. 00141 The dome 4 is domed on its top.

00142 The curvature line runs in the direction of inclination

00143 tion of the roofing plate 1 seen as a circular

00144 never around a radius point P. The radius point P is in

00145 a short distance above the top of the roof

00146 kungsplatte 1 and intersects the longitudinal central axis x-x

00147 of the tube 2. Said radius point P can, however, also lie 00148 in the plane of the roofing plate 1 or 00149 but even slightly below it, in which case

00150 then a fork-shaped bearing would be designed

00151 itself run essentially parallel. 00152

00153 Although the Dom 4 is semi-spherical

00154 could be, since it is spatially parallel to the longitudinal edge

00155 edged l ^{1 of} the covering plate 1, namely

00156 essentially to the extent of the outer diameter

00157 of the tube 2, so that the one elongated shaft

00159 cross-section of circular tube 2 supporting and leading

00160 nestle. The shaft ends with the crown area

00161 merge into the dome side walls 4 'in a narrow curvature,

00162 which are themselves essentially parallel to one another

00165 The dome-shaped top of the dome 4 is overlapped

00166 fen from a hood also penetrated by tube 2

00167 part 5. At least that on the dome-shaped upper part

00168 te on the inside is designed to fit.

00169 The hood part 5 can be guided in the inclination

00170 level practically ball-jointed directional

00171 shift and thus the angle of inclination of the tube 2nd

00172 towards the roof covering plate 1, according to

00173 according to the length of the passage hole 3. Here

00174 gen, enriched by turning, based adjustment ranges 00175 en, which enables the vertical alignment of the tube 2

00176 chen. 00177

00178 For example, for the narrowest possible guidance system

00179 of the tube 2, the hood part 5 sits roof-mounted 00180 in a cross-section of the tube 2 adapted

00181 collar 6 on. Its free front edge is cut flat

00182 ten, i.e. it runs perpendicular to the longitudinal central axis

00183 x-x of the tube 2. The flat end face is appropriate

00184 stepped rotationally symmetrical. The higher level is

00185 inside. With a correspondingly opposite configuration

00186 of a connector is water entry through this

00187 S-joint avoided. 00188

00189 The superposition of the hood part 5 on the dome 4 is

00199 directed end decaying on the jacket wall

00200 or wedging ramp 8 from (see FIG. 3).

00201 The other end of the retaining ribs pointing outwards

00202 7 forms one in the pivoting plane of the tube 2

00203 extending, i.e. correspondingly concentric to the radius

00204 point P, rounded end face 9. 00205

00206 The end faces 9 of the retaining ribs 7 are on the

00207 underside 10 of the roofing plate 1, namely

00208 in the area of the vertical guide shaft

00209 the cathedral side walls 4 '. In the middle, tangent 00210 zone, these roof side walls 4 'form a

00211 running direction downwardly open storage trough 11. Die

00212 bearing trough 11 has a circular curvature of the front

00213 area 9 corresponding trough bottom, but according to

00214 diverging course of the subsequent trough flanges

00216 whose opening angle the inclination adjustment range or

00217 movement space requirement of tube 2 taken into account. To at

00218 of the relatively small wall thickness,

00219 can the bearing trough 11 by peripheral wall offset

00225 The curved end face 9 runs transversely to the longitudinal center

00226 telaxis x-x of tube 2; the flanks run the same way

00227 of the storage trough 11. In this way,

00228 te the roof covering plate 1 practically a hook-like

00229 ge support of the tube 2 by the exposed holding

00230 ribs 7 reached. 00231

00232 As can be seen in the drawings, the pipe 2 runs

00233 uninterrupted from the top of the roof

00234 to. Underside of roof. 00235

00236 The hood part 5 is on the outer surface of the tube 2,

00237 passed through the collar 6, freely movable. 00238

00239 The hood part 5 is against a screw ring 12

00240 braced the dome-shaped top of the dome 4.

00241 Turning the screw ring 12 accordingly

00242 the pipe 2 upwards, i.e. towards the arrow

00243 les y pulled this until it is

00244 tongue of the holding ribs 7 in the bearing trough 11 comes. The 00245 internal thread 13 of the screw ring 12 is in the range

00246 self-locking. An additional screwed on

00247 screw ring 12 would the position-securing counter-

00248 NEN. 00249

00250 As can be seen in the drawings, the screw ring 12

00251 designed as a nut penetrated by tube 2. As

00252 nut assigned to the nut has attack surfaces, so that an auxiliary tool can be attached

00254 (wrench). In general, however, that of

00255 Hand-applied torque.

00256

00257 The interacting with the internal thread 13, as an external

00258 thread realized counter thread 14 needs of course

00259 only above the dome 4 on the jacket wall of the tube

00260 2 to begin. It stretches a good distance from there

00261 to over the collar molded onto the hood part 5

00262 6. It is relatively short. So there is no double

00263 tube roof duct. 00264

00265 The counter thread 14 is expediently located

00266 also in the upper end region 2 ^{1 of} the quite long pipe 2.

00267 Here it can (14) independently of the screw ring 12

00268 screwing assignment of an additional part,

00269 for example for assigning a roof hood, one

00270 mesh basket or the like end piece. Is shown

00271 a mesh basket 15 to prevent the entry of

00272 foreign bodies in the tube 2. 00273

00274 Of course, the screw ring counter thread

00276 stand length of the tube 2 up to the end region 2 '

00277 extend. One is at the same time with regard to the

00278 length of the collar 6 independently.

00279 00280 Coming back to the stepped shape of the collar 6,

00281 the lower end face transmitting the clamping pressure

00282 before the screw ring 12 has the appropriate counter stage

00283 zen (see drawing, Figure 2). 00284

00285 While the load in the solution according to FIG. 1

00286 axially on the upwardly directed collar 6 of the hood

00287 partly goes, the variant according to FIG.

00288 det that the collar 6 itself the bracket and

00289 applies clamping force securing the inclination. He

00290 itself is made of hard PVC. Here is the screw ring

00291 12 from the upper region of the collar 6 of the hood part 5

00292 formed. Its thread is also designated 13.

00293 The lower area of the collar 6 and the actual

00294 before hood-forming hood wall W consist of

00295 elastically evasive material. It is a matter of

00296 soft PVC. The latter (W) is like a flexible apron

00297 designed, which the rotationally asymmetrical mountain

00298 and descent due to the flattening of Dom 4 and

00299 hood part 5 does the best and finally into the

00300 desired cuddly, sealing end position

00301 occurs in which the overall element hood part / collar

00302 5/6 is stretched against the top of the dome 4. The 00303 cap shape of the hood part 5 surprisingly favors the resetting of the hood wall W. 00305

00306 Such an overall element 5/6 can be injection molded

Master 00307 perfectly. It is the so-called

00308 Two-component syringes. 00309

00310 At the lower end 2 '' of tube 2 is a harmonic

00311 as a connecting hose 16 to a further one

00312 pipeline or the like connected, held

00313 by a clamp 17. 00314 00315 Figures 4 and 5 give a further development in the

00316 Figures 1 and 2 shown basic shape of the roof passage

00317 leadership D, namely training with regard to

00318 the avoidance of water entry. The clamping technology

00319 means are retained in their basic system, the reference numbers 00320, partly without repeated text, 00321 applied accordingly.

00322

00323 The core of the training is the arrangement

00324 a ring seal RD between the top of the

00325 collar 6 and the jacket wall of the tube 2, designated

00326 as pipe wall 18. The ring seal RD sits in one of the 00327 joints F between the said collar end and the pipe

00328 wall 18 upstream shell wall groove 19 des

00329 Rohres 2. It is an annular groove with a

00330 lower shoulder 20. The latter stands essentially

00331 perpendicular to the longitudinal central axis x-x of the tube 2

00332 and serves as a support and for the roof-side axial

00333 Support of a sealing element that forms the ring seal RD

00334 tion O-ring 21. The latter is made of rubber or

00335 rubber-like material and has in the usual way

00336 functional flexibility or elasticity. 00337

00338 The inherently circular cross-section of the sealing

00339 O-ring 21 is supported except on said shoulder

00340 20 also directed radially inwards on the essentially

00341 chen cylindrical groove base 22 of the wall wall

00342 from 19. The latter is formed by an inward

00343 offset, cylindrical section of the tube wall 18. 00344

00345 The sealing counter surface is resp.

00346 tive of the mother. The latter loads the ring 21

00347 in the sense of sealing against its restoring force

00348 deforming. 00349 00350 In the exemplary embodiment shown, the

00351 speaking load indirectly in the seal O-ring

00352 21 a. For this purpose, the collar 6 sits in one of the

00353 screw ring 12 loaded, the collar 6 free-standing

00354 molded lip 23 continued. The uninterrupted circular

00355 shaped circumferential lip 23 becomes radial under one

00356 inward pressure component against the ring 21

00357 the ring seal RD pressed. That seals the upper one

00358 entrance of the joint F from. Circularly at home

00359 cross section of the ring 21 arise in the transverse

00360 seen cut, three sealing points distributed over the circumference

00361 denoted by a, b and c. The first (a) is

00362 directed essentially radially inwards, at the groove base

00363 22, the second (b) in the axial direction on the horizontal shoulder 20 and the third (c) peripherally on the 00365 inside of the lip 23 which transmits the tension force. 00366 The latter sealing point c lies essentially in the

00367 bisectors between the approx. 90 °

00368 the first two sealing points a and b. 00369

00370 This seal-promoting variety of sealing points

00371 a, b, c depends not insignificantly on the special

00372 direction of the lip 23 together. Like especially from figure

00373 5 can be seen, the procedure is such that the lip

00374 23 at an acute angle to the longitudinal central axis x-x of the tube 2

00375 is aligned. The rotationally symmetrical

00376 lip 23 extends obliquely upwards and

00377 directed inside. The helix angle is alpha

00378 draws and encloses approx. 30 °. The lip 23 forms

00379 an exposed cone. 00380

00381 The free end of lip 23 protrudes at least into

00382 lung (Figures 4 and 5), partially into the jacket wall groove 00383 19 of the tube 2. The inner edge of the free end 00384 of the lip 23 takes a distance z from the groove base 00385 22 a, which is significantly smaller than that from home

00386 circular diameter of the seal O-ring 21.

00387 this distance z is moderate even in the unloaded state

Given 00388, so that the ring 21 is not yet in

00389 Tensioned position of the captive nut on the

00390 roof duct is held. The lip 23 acts

00391 as a friction protection against the rotationally secured

00392 insert seal O-ring 21. 00393

00394 The upper horizontal end face 24 of the collar 6 ends

00395 level even in the tensioned state still clear

00396 below that due to the horizontal

00397 ter 20 level. Tube wall 18, d. H. the mantle

00398 wall and the tip plane of the counter thread 14 of the raw

00399 res 2 run essentially level with the cylinder

00400 drisch. Those in a peripheral zone of the forehead 24

00401 rooting lip 23 is over a flock-forming material

00402 tial bridge connected, the somewhat smaller in cross section

00403 is defined as the thickness of the

00404 ten Lippe 23. The corresponding hinge point bears

00405 the reference number 25. In the unloaded basic position

00406 the angle alpha of the lip 23 can be somewhat smaller

00407 are therefore below 30 °. 00408

00409 To exercise a full support system between the

00410 back of the lip 23 and that formed by the screw ring 12

00411 th nut, the screw ring 12 has a suitably inclined

00412 standing printing surface 26. It is about a

00413 funnel-like recess or chamfer in the area of

00414 lower inner edge of the screw ring 12. The corresponding

00415 chilling chamfer sets at the foot of the internal thread 13 of the

00416 screw ring 12 and goes over a third of the

00417 lower ring end face of the mother. 00418 00419 Compared to the tensioning effect of the screw ring

00420 12, the ring seal RD acts as a damping element,

00421 so that in the direction of arrow y going tension

00422 increasingly a counterforce protecting the retaining ribs 7

00423 effect occurs. The lip 23 presses against via ring 21

00424 the shoulder 20. 00425

00426 There is also an independent readjustment

00427 Effect via the restoring force of the seal O-ring

00428 21. 00429

00430 You can see the ring seal RD by the thread

00431 en 13/14 entering moisture at an entry into the

00432 joint F prevented. A corresponding water entry is

00433 due to the load-bearing flank of the thread

00434 13/14 about the one leaving a spiral gear, not

00435 bearing flank area is possible in principle, if

00436 non-joint sealing materials (paste, tow

00437 or the like) block this path. In any case 00438 the water is stopped at the level of the ring seal RD. 00439
