Description

The invention relates to an attachment base, in particular for roof openings, z. B. for smoke and heat exhaust systems, with the features of the preamble of claim 1.

Due to the conical shape of the foot-side opening to the top opening for flows of gas, smoke or the like running in this direction, conical attachment bases designed in this way are particularly streamlined and highly effective with very good characteristic values.

From the DE 71 18 656 U is an attachment base of the type mentioned above, with the vertical slightly inclined side walls having an upper and lower flange, wherein the upper flange has a downwardly folded bar. The adjacent abutting edges of the side walls may be folded and in this area by screws, rivets, bolts u. Like. Be connected. Instead, the impact edges can also be connected by an elbow and in that screws in holes in the edges of the Sidewalls and be stuck in the elbow. The accuracy of the position of the side walls to each other is achieved by Paßnieten or dowel pins in the upper and lower flanges. First, screws are inserted in the corner areas and tightened so far that an alignment of the side walls against each other is still possible. The alignment is done so that there is a right angle between the adjacent side walls. Thereafter, bored through a bore of the upper flange and a bore of the lower flange through respective holes on the other upper and lower flange of the other side wall and inserted a Paßniet or a dowel pin in the holes, which ensure that the angular accuracy of the interconnected side walls maintained. Thereafter, then takes the final tightening of the screws in the side edges of the side walls and in the elbows.

A funnel-shaped attachment base of this known type is complicated and requires a complicated assembly at the application. There are screws for corner fixing screw between the elbows and the side walls necessary and other tools for the screw. Furthermore, alignment work for producing a right angle of the side walls to each other are necessary and the introduction of holes and Paßnieten or dowels.

From the US 5,465,533 A rectangular top boxes are each known with vertically directed side walls, in which the side walls are connected in the region of the abutting corners by means of corner joints. The corner connectors consist of rectilinear angle pieces with vertically aligned tongues, which can engage behind holders made of the material of the side walls. Due to the vertically extending side walls does not arise in oblique side walls problem of connection in the corner areas. From the US 6 041 557 A Rectangular boxes with vertically directed side walls are known, which are also connected in the corner areas with corner connectors, in which case the corner connectors vertical directed have tongues and have the side walls of these notched latch, which are engaged by the tongues of the corner connector.

From the DE 20 2005 016 555 U1 For example, a curb construction with sloping sidewalls is known in which each side wall has tabs on one side edge and slots on the other side edge for inserting tabs of another side wall. In the head area, a rivet connects the stepped sheets and in the foot area, these are connected by two rivets. From the DE 20 2006 000 881 U1 funnel-shaped attachment base with oblique side walls are known which have at one longitudinal edge protruding tabs and at the other longitudinal edge slots for receiving such tabs. In the area of the corners of the top and bottom flanges are fasteners that are riveted, bolted and / or glued.

From the DE 201 17 790 U1 Supplementary pedestal are known with vertically directed side walls, in which the side walls have at one edge in the corner region projecting, downwardly directed hooks and associated, provided in this corner area so to side walls at the level of the hooks with slots for the engagement of the hooks are provided.

There are also such plastic top or plastic in particular known in which the side walls are connected in the corner regions in particular by welding and the base frame thus represents a finished frame structure. These are complicated and expensive to manufacture. They have the great disadvantage that these finished top pedestals have a large footprint due to their dimensions, be it in terms of stock availability or in terms of transport from the delivery site to the site.

The invention has for its object to provide a conical attachment socket of the type mentioned, which is inexpensive to produce, easy to assemble and can be stored and transported in a small footprint.

In Fig. 1 a fully assembled top 10 is shown, in particular for roof openings, for. B. for smoke and heat exhaust systems, is suitable and intended. Such top pedestal 10 are formed as an approximately square to rectangular peripheral base frame 11 having a top opening 12 and a foot-side opening 13. In the base frame 11 of interest design here, the top opening 12 is smaller than the foot-side opening 13. In this case, the base frame 11 of the foot-side opening 13, starting from the top opening 12 towards conical obliquely facing wall surfaces 14 to 17. Such designed conical attachment base 10 are due to the conical shape of the foot-side opening 13 to the top opening 12 for extending in this direction streams of gas, smoke od. Like Particularly streamlined and highly effective with very good in this regard characteristics. Known attachment base 10 of this type made of plastic or in particular of metal, in which the side walls are connected in the corner regions in particular by welding and the base frame 11 thus represents a finished frame structure, are expensive and expensive in the production. They also have the disadvantage that these finished attachment base 10 due to their dimensions have a large footprint, be it in terms of availability in stock or in terms of transport from the delivery site to the site.

These disadvantages are eliminated in that the attachment base 10 is kept ready as a kit with individual components that can be assembled together only in the region of the mounting location for forming the attachment base 10.

Such a square to rectangular encircling base frame 11 has as a kit for forming the four side walls individual rectilinear longitudinal profiles 18 to 21 square to rectangular contour, with two longitudinal profiles 18, 20 on the one hand and two longitudinal profiles 19, 21 on the other hand are designed the same. The two longitudinal profiles 18, 20, which face each other in the base frame 11, are identical and of equal length and longer than the two other longitudinal profiles 19, 21 which are approximately perpendicular to the longitudinal profiles 18, 20. These short longitudinal profiles 19, 21 are also identical and the same length and designed as short parts. Out Fig. 1 and 2 recognizes that on two sides of the base frame 11 formed as a short part longitudinal profile 19, 21 between two formed as a long part longitudinal profiles 18, 20 is added. It is understood that the conditions can also be reversed in such a way that instead a long part is accommodated between two short parts.

The kit comprising the longitudinal profiles 18 to 21 for the base frame 11 furthermore has a total of four corner connectors 40 to 43, by means of which the four longitudinal profiles 18 to 21 can be detachably connected to each other in particular by respective plug connections.

As in particular from Fig. 3 to 6 it can be seen, the individual longitudinal profiles 18 to 21 are each formed of quadrangular plates and have an angled upper side, preferably angular in cross-section collar 22 to 25, which runs around in the assembled state of the top 10. On the underside and in the region of the foot-side opening 13, the individual longitudinal profiles 18 to 21 are provided with an angled lower contact flange 26 to 29, wherein all the contact flanges 26 to 29 extend within a common, in the installation, in particular horizontal plane. Between the upper-side collar 22 to 25 and foot-side contact flanges 26 to 29 extend the inclined wall surfaces 14 to 17. In between, the latter and the respective upper-side collar 22 to 25, may still be provided a non-oblique interface 30 to 33.

It can be seen that only two pieces of such longitudinal profiles 18, 20 are necessary for the attachment base 10 in the form of the base frame 11, which are formed as a long part and designed identically. Similarly, only two longitudinal profiles 19, 21, which are designed as short parts and are also identical, are required. This means that for the longitudinal profiles 18 to 21, only one type serving as a long part and one serving as a short part type are to be produced and kept ready. This reduces the number of different components and leads to a significant reduction in manufacturing costs and space requirements.

Starting from the in Fig. 4 and 6 shown, not yet folded square plates to form a long part according to Fig. 3 or a short part according to Fig. 5 become the square plates according to Fig. 4 respectively. Fig. 6 on the visible lines folded so that in each long part according to Fig. 4 and 3 the approximately angular in cross-section collar 22, 24, the inclined wall surface 14, 16 and the lower Aufstandsflansch 26, 28 and between the collar 22, 24 and the inclined wall surface 14, 16, the non-inclined intermediate surface 30, 32 result. The finished beveled, a long part forming Longitudinal profile 18, 20 results Fig. 3 and is for assembly to the base frame 11 in Fig. 1 placed either on the left or on the top right or on the display according to Fig. 2 left and right.

The from the fold of the plate according to Fig. 6 obtained, a short part representing longitudinal profile 19, 21 results from Fig. 5 and is in accordance with the assembly Fig. 1 each between two long part forming longitudinal profiles 18, 20 added. The composite longitudinal profiles 18 to 21 of the base frame 11 in the corner areas with the non-oblique intermediate surfaces 30 to 33 and / or the respective upper-side collar 22 to 25 to each other, where there are respective corner joints.

For the formation of the base frame 11 two different types of corner connectors 40 and 42 are provided in the region of the corners, wherein the corner connector 40 in place of the corner connector 43 in Fig. 1 as the same type can occur. The same applies to the corner connector 42, which is used as the same component as a corner connector 41. In that regard, only two types are required for these corner connectors, whereby the effort is further reduced. These two types are in Fig. 7 to 9 shown. The corner connectors 40 to 43, in particular one type 40, 43 and likewise the other type 42, 41, are each formed from two folding parts folded to form an angle part in the form of approximately right-angled triangles, which are integrally connected in the region of the triangular hypotenuse. In FIGS. 7 and 8 is for the local corner connector 42 shown that this is integrally formed from two similar folding parts 42 a and 42 b, which are integrally connected in the region of the triangular hypotenuse and forming an angle according to Fig. 8 worked out. In Fig. 9 For the other type of corner connector 40, it is also shown that this too is formed of two folding parts 44a and 44b, which are likewise integrally connected in the area of the triangular hypotenuse and folded to an angle.

The corner connectors 40 to 43 have edge z. B. two spaced apart in the longitudinal direction at the edge hook, of which in Eckverbindertyp 42 according to FIGS. 7 and 8 the hooks at the edge of the folding part 42a 42c and the folding part 42b are designated 42d. It can be seen that the hooks 42c in FIGS. 7 and 8 directed downwards, wherein between the hook 42c and the edge of the flap part 42a, a slot-like gap is formed. The hooks 42d on the outer edge of the other flap part 42b are directed in the drawing upwards, wherein also between the hook 42d and the edge of the flap part 42b, a slot-shaped gap is formed.

The other Eckverbindertypus 40, 43 are also respective hooks 44 c and 44 d are provided, these hooks are oriented in opposite directions, such that the hooks 44 c at the edge of in Fig. 9 left flap portion 44a are directed downward, while the hooks 44d at the edge of the other flap portion 44b are directed upward, each leaving a gap between the respective hook and the edge of the flap portion 44a and 44b, as in FIGS. 7 and 8 the case is. It can be seen that in the two corner connector types 42 according to FIGS. 7 and 8 on the one hand and 40 in accordance with Fig. 9 On the other hand, the hooks are only provided laterally reversed. This means that as a blank for the formation of the corner connectors 40 to 43 only one copy is necessary, analogous to the representation in FIG Fig. 7 , Wherein a total of four pieces are required for the base frame 11 of this component. Two pieces are taken along the triangular hypotenuse in one direction, e.g. B. on the left, while two other identical types are folded in opposite directions along the same line on the right, resulting in the two different types according to Fig. 8 and 9 result. The hooks 42c, 42d and 44c, 44d are bent approximately at right angles. This makes it clear that a considerable saving in manufacturing and material costs is achieved even with regard to the corner connectors 40 to 43.

With regard to the corner connectors 40 to 43, it should be noted that the in Fig. 8 and 9 shown types 42, 40 of a blank according to Fig. 7 by folding in are formed in one direction or in the other direction. The protruding at the edges hooks 42c, 42d, 44c and 44d are each arranged at the edge of the corner connector, which forms the counter-catheter of the triangle in the right triangle. Per edge, the hooks are approximately parallel to the edge line.

The individual longitudinal profiles 18 to 21 have at the edge regions of the obliquely directed wall surfaces 14 to 17, with which these rest against the corner connectors 40 to 43, recesses in the form of z. B. of slots for hooking the hook 42c, 42d, 44c, 44d. The designed as a short part longitudinal profile 19, 21 has on in Fig. 6 right edge area z. B. two spaced recesses 34 and equally two recesses 35 on the left edge. In an analogous manner, the longitudinal profiles 18, 20, designed as long parts, are in the Fig. 4 right edge region recesses 36 in the form of slots and on the left edge region just such recesses 37. If you compare Fig. 6 and Fig. 4 with each other or Fig. 5 With Fig. 3 , it can be seen that the distance between the recesses 34 from the transverse edge of the longitudinal profile 21, 19 is less than the distance that the recesses 36 have from the transverse edge of the longitudinal profile 18, 20 designed as a long part. Since the respective plates are designed to be symmetrical in folding to form the longitudinal profiles, the same applies to the spacing of the recesses 35 from the transverse edge of the longitudinal profiles 21, 19 designed as short parts and equally also to the spacing of the recesses 37 from the transverse edge of the longitudinal profiles 18, 20 designed as long parts ,

In particular from Fig. 4 and 6 recognizes that in a row with the recesses 34 to 37 per edge region another approximately slot-shaped recess 38 and 39 in the longitudinal profile 21, 19 and in the same way a slot-shaped recess 88, 89 in the longitudinal profile 18, 20 is provided, in each case in the transition region between the collar 25, 23 or 22, 24 and the intermediate surface 33, 31 and 30, 32nd

The composite longitudinal profiles 18 to 21 of the base frame 11 close to each other in the corner areas with the non-oblique intermediate surfaces 30 to 33 and the respective upper-side collar 22 to 25, wherein in the region of the collar 22 to 25 at the corners in Fig. 1 and 2 such as Fig. 12 indicated corner brackets 53 are provided which each connect two abutting collar positively with each other. The corner brackets 53 each have an angle piece 54, which may abut in the region of the corners and abutting collar 22 to 25, preferably on the inside thereof. On both sides of the angle 54, projections 55 and 56 close, which have the shape of tongues and approximately parallel to the longitudinal extent of the angle piece 54, wherein over a portion of the course length, a slot 57 and 58 is provided.

For the assembly of the base frame 11 to form the attachment base 10, the order of mounting is basically arbitrary. For example, it is possible to initially provide each longitudinal profile 18 and 20, which is designed as a long part, with corresponding corner connectors 40, 41 or 42, 43. For this purpose, z. B. a corner joint 40 with the flap portion 44a applied from the inside to the inclined wall surface 14 of the longitudinal profile 18, wherein the downwardly directed, approximately rectangular hooks 44c engage through the recesses 37 and thereby the corner connector 40 is suspended from the longitudinal profile 18. In the same way, on the opposite, also formed as a long part longitudinal profile 20, z. B. forward, a corner connector 42 according to Fig. 8 are applied from the inside to the inclined wall surface 16 with the flap part 42a, wherein here also the downwardly directed, rectangular curved hooks 42c engage through the slot-shaped recesses 36 and thereby the corner connector 42 is mounted. Both corner connectors 40, 42 are suspended from the longitudinal profile 18 and 20 and thus ready for mounting a longitudinal profile formed as a short part 19, which can be placed between the longitudinal profiles 18 and 20. In this case, put the folding parts 44b and 42b of the corner connectors 40 and 42 back to the inclined wall portion 15 of Longitudinal profile 19, wherein the approximately right-angled hooks 44d and 42d engage through the slot-shaped recesses 34, 35 and thereby the longitudinal profile 19 is held down securely hanging on the corner connectors 40, 42. The attachment base 11 is prepared in particular by the hooks 42c, 42d, 44c, 44d of the corner connectors 40 to 43 oriented in opposite directions and approximately at right angles and the additional corner clamps 53 for mounting on the roof opening.

In an analogous manner for the assembly of the base frame 11 at the rear ends of the two formed as long parts longitudinal profiles 18, 20 corresponding corner connectors 41, 43 are attached, wherein the attachment of the corner connector 41 in the same manner as that of the corner connector 40 happens and wherein the attachment of the other corner connector 43 in the same manner as that of the corner connector 42 happens. Thereafter, the two corner connectors 41 and 43 at the other end of the two designed as long parts longitudinal profiles 18, 20 are suspended. Then can be placed between the longitudinal profiles 18, 20 designed as a short part longitudinal profile 21, which is analogous to the longitudinal profile 19 attached to the hooks of the corner connectors 41, 43 and suspended.

To ensure the dimensional stability of the corner brackets 53 can be inserted from above into the respective recesses 38, 39 and 88, 89 such that their projections 55, 56 in the form of tongues through these recesses 38, 39 and 88, 89 reach through and are received in a form-fitting manner, wherein the angle piece 54 can be found on the inside of each corner conditioning.

It can be seen in the finished assembled base frame 11, that while the two formed as short parts longitudinal profiles 19, 21 are applied with their double edge areas from the outside to a respective folding part 44b, 42b of a corner connector 40, 42 and 41, 43 and its upward Hook 44d, 42d engage in the associated recesses 34, 35, in particular slots, such that the longitudinal profiles 19, 21 formed as short parts are held suspended from the corner parts.

The longitudinal profiles 18 to 21 are formed as sheet metal profiles. The corner connectors 40 to 43 are also made of sheet metal, as well as the corner brackets 53. These components that make up the kit, can be easily and inexpensively. They are simple and allow for the extremely small footprint storage and transportation to the assembly site with very little space. The individual components for forming the base frame 11 can be cut in a cost-saving manner as sheet metal parts. They are easy to handle and enable simple and quick installation without the need for auxiliary tools, which requires no special knowledge. An attachment base 10 of the type described in the design as a conical base is therefore extremely cost-effective overall.
