Definitions
- the invention relates to a straight connection piece for partial, preferably approximately half, engagement in hollow profiles to be connected to one another on the end face, which serve to form a spacer frame or as a spacer for insulating glass panes, the cross section of the straight connection piece fitting into the inner hollow cross section of the hollow profile and at least in some areas corresponds approximately to and on its back facing the outer transverse web of the hollow profile in the central region has a recess into which the mutually facing ends of the outer transverse web of the hollow profile can be deformed.
- Such a straight connector is known from EP 0 133 655 B2 and from EP 0 330 906 B1 and has proven itself in particular with regard to the mutually aligned alignment of the hollow profiles or hollow profile parts to be connected.
- the recess on the back of these known straight connecting pieces has a shallow depth and is delimited at the lateral edges by a raised area. Furthermore, a flat spacer is arranged protruding within the depression, so that the depth of the depression is further reduced at this point. Thus, this recess allows only a slight pressing with the outer crossbar of the hollow profiles to be connected.
- the known straight connecting pieces In order to nevertheless form a tight joint of the hollow profiles at the connection point, the known straight connecting pieces have stop projections which keep the end faces of the hollow profiles to be connected at a distance.
- transverse webs are arranged within the U-cross section, which are spaced from one another in the central region of the straight connecting piece, so that the outer transverse web of the hollow profile can be bent somewhat into the interior of the straight connecting piece, insofar as this permits the side webs of the hollow profile in this area.
- the outer crossbar of the hollow profile can only be pressed slightly inwards, as a result of which a narrow opening is formed between the outer end faces of the crossbars of these hollow profiles in order to allow sealing compound to enter.
- this straight connection piece On the side facing the internal cross section, this straight connection piece also has a spacer in order to produce a joint running around the joint between the hollow profiles to be connected.
- the depression at the back of the straight connector extends over its entire width and is open to the transverse web of the hollow profile arranged on the outside in the use position, in that this depression is narrow and from steeply sloping end faces of webs or steeply sloping walls leading to it or transversely running edge edges of an opening and that the mutually facing ends of the outer transverse webs of the hollow profiles to be connected are bent after being deformed into the recess and are plastically elongated or deep-drawn.
- the gap formed by deep drawing on the outer crosspieces of the hollow profiles can be filled beforehand or subsequently with sealing compound, the extension over the entire width of the straight connecting piece leading to a correspondingly complete filling with sealing compound which extends to the side webs and thus to a good one Sealing leads.
- a special embodiment of the straight connection piece according to the invention can consist in that parallel back walls are provided on its back up to the in particular central depression, which delimit recesses located on the back on both sides of the depression.
- the recesses continue into the recess and form a continuous channel in the position of use which is closed by the hollow profile at the back of the straight connection piece, and that the recesses and the recess have a greater depth than the engagement of the deformed crosspieces corresponds to the end faces of the hollow profile.
- the sharp-edged bending and deep-drawing of the crossbars only occurs on the in Parallel side webs extending in the longitudinal direction, but this is sufficient to bring about the effects of a contraction of the two hollow profiles to be connected, which have already been explained.
- a channel remains inside the straight connector, which can be filled with desiccant or, when adding desiccant, also allows it to pass through the connection point.
- hollow profiles can be connected to the straight connecting piece before the bending to a frame begins and before a last connection point on such a frame to be bent is closed with a straight connecting piece. So practically endless hollow profiles can be produced with the straight connector in order to be able to subsequently bend spacer frames of different sizes.
- the edge at the entry into the depression of the straight connector can be approximately rectangular or possibly acute-angled and the mutually facing boundaries of the depression can in particular run parallel to one another and approximately at right angles to the longitudinal direction of the straight connector.
- the walls running up to the depression and forming them over part of the slurries or walls running over the entire width or a depression made in the back of the straight connection piece therefore have a steep, approximately rectangular edge, on which the outer transverse webs of the, despite a relatively narrow depression hollow profiles to be connected can be bent and deep-drawn accordingly.
- connection between the straight connecting piece according to the invention and the hollow profiles is ended by the aforementioned deep-drawing of the outer transverse webs of the hollow profiles on the sharp edges of the recess, sealing compound can already be inserted from outside into the resulting slot-like opening between the panes of insulating glazing introduced and a good seal and seal prepared. Especially after the application of the individual panes on the outside or the back of the hollow profiles, sealing can take place and the sealing compound penetrate into the resulting slot-like opening at the connection point of the hollow profiles and bring about a good seal.
- the straight connecting piece can be adapted with its cross-section to a hollow profile with parallel side webs and two spaced-apart cross webs, in which in the use position between the outside cross web and the side webs in each case somewhat oblique or convex or concave cross-sectional webs are provided, the depth of the depression being approximately corresponds to the cross-sectional depth of the hollow profile bridged by the transition webs or - in particular slightly - exceeds them.
- the transition webs can thus also be bent and deformed somewhat inward, so that this deformation process at the back of the straight connecting piece does not lead to reaction forces on the side webs of the hollow profile in the sense that they deflect outwards and are bulged.
- the outer surfaces on these side webs thus remain parallel and thus retain their dimensional accuracy, which is of great importance for the tight contact of the panes of the insulating glazing with these webs.
- the extent of the inward or deep-drawn parts of the outer transverse webs of the hollow profiles depends on the width of the depression extending in the longitudinal direction of the straight connector. So that they have a sufficiently large dimension to enable a correspondingly good effect when deep-drawing and when connecting and sealing, it is advantageous if the width of the depression in the longitudinal direction of the straight connector is approximately twice as large as its depth. If necessary, the width versus the depth also be more than double, so that the parts of the outer transverse webs of the hollow profile which are to be bent inward also find sufficient space.
- the deep drawing on the steep and expediently sharp-edged boundaries of the depression prevents the side webs from bulging or bulging because the waste into the depression and its sufficient depth exerts a strong pull on the material and even leads to a cold flow can lead.
- the material of the hollow profiles is thus drawn into the recess, which also continues on the transition webs, so that bulging to the sides is avoided.
- An embodiment of the straight connector according to the invention for further improving the mutual alignment of the hollow profiles can consist in that on the underside facing away from the recess up to a central notch run-up bevels are provided and that the underside notch has a cutting degree present on the end faces of the hollow profiles to be connected in the use position receives.
- a degree of cutting directed into the interior of the hollow profile especially at the crossbar facing the interior of the insulating glass pane in the position of use.
- run-on bevels on the top and / or on the bottom of the straight connection piece which rise in each case directed towards one another, can each be offset laterally relative to one another with respect to the longitudinal center of the straight connection piece.
- the run-up slopes are arranged asymmetrically with respect to the longitudinal center, so that one run-up slope on one side can form a stop for the hollow profile pushed on from the other side.
- This can be provided on the outside or top as well as on the bottom or the inside of the straight connector, so that the center finding for the hollow profiles can be further improved.
- At least the depression is at least partially filled with a sealing compound, into which the mutually facing edges of the outer transverse webs of the hollow profiles to be connected can be pressed during their deep-drawing.
- the deep-drawing of the crosspieces can thus be used to pressurize a sealing compound previously provided on the straight connector so that it creeps into cavities and under the deformed web parts of the hollow profile and causes the free cross-sectional areas to be filled with sealing compound as best as possible.
- the deep-drawing process for pulling together the ends of the hollow profiles to be connected and for firmly connecting them to the straight connecting piece can thus also be used in this case to press sealant into intermediate and hollow spaces and to achieve the best possible distribution of this sealant.
- An embodiment of the straight connecting piece in particular one which previously contains a filling of plastically elastic sealing compound in the region of its depression, can consist in that the depression on the narrow sides of the straight connecting piece has a flat continuation, into which sealing compound at least when the hollow profiles are pressed is movable from the central recess into the area of the side webs.
- the process of pressing and deep-drawing the outer transverse webs can be used to distribute sealing compound previously applied to the straight connecting piece. Due to the flat continuations mentioned on the narrow sides of the straight connecting piece, sealing compound can thus be pressed specifically into this area of the side webs, so that these areas are also well sealed, this sealing process being associated with the pressing, deep-drawing and connecting, and therefore does not require a separate process step.
- At least one channel leading to the underside and in particular a flat depression into which the channel opens can be provided in the bottom of the depression.
- At least one channel leading to a depression on the underside is provided at the foot of the walls delimiting the depression.
- the sealing compound which is also pressurized during deep drawing along the walls delimiting the depression, is pressed into corresponding channels and moved to the depression on the underside.
- the straight connector can be made of metal or die-cast or hard plastic or from a stamped and bent sheet metal part. All these materials and types of manufacture enable the recess according to the invention to be provided on the back of this straight connecting piece, into which the transverse webs in the use position, which form a spacer or spacer frame for insulating glass panes, can be deformed and deep-drawn.
- a straight connection piece designed as a sheet metal part can have an approximately U-shaped cross section, which is adapted to the inner cross section of the hollow profile, and the U transverse web of the sheet metal part can have the depression, which is in particular punched out.
- a very simple straight connection piece made of sheet metal can be bent, in which the recess is provided by a stamping or other shape, which at the same time can have the sharp-edged edge already mentioned.
- the U cross-section can be on the side facing away from the depression between its U legs, at least in an area projecting beyond the depression on both sides, by means of a seal, for example an inserted foam seal and in particular one arranged between the U crosspiece and its depression and this seal plastic-elastic sealant must be filled.
- a seal for example an inserted foam seal and in particular one arranged between the U crosspiece and its depression and this seal plastic-elastic sealant must be filled.
- An advantage that applies to practically all of the exemplary embodiments can also be seen in the fact that a depression is formed in the areas of the outer transverse webs of the hollow profiles to be connected, which are close by deep-drawing the butt joints, which are well filled with sealing compound or when sealing an insulating glass pane with sealing compound can and then provides a correspondingly larger cross-sectional thickness of the sealing compound in this area of the joint.
- connection of the two hollow profiles at their end faces can be done very easily by inserting a part of the straight connecting piece into each of the two hollow profiles or by pushing the hollow profiles over the straight connecting piece, so that they both extend to the depression located in the middle. Then, for example, a pressure stamp on the outside of the joint can be deep-drawn in the manner described, which pulls the two hollow profiles even better together due to the material flow and the tensile forces exerted on the material and prevents bulging in the side areas.
- the transverse webs to be deformed can each be bent and deep-drawn in their edge region around the walls, which laterally delimit a channel running on the outside or the back of the straight connector.
- sealing compound located in such a channel forming a depression can be pressed and squeezed into cavities from which the air located there can be displaced at the same time.
- the one at the The outside of the straight connector in its longitudinal direction can also be designed so that it also extends over the area of the recess, so that when filling desiccant this can pass through the straight connector even after the deep-drawing process.
- the mutually facing edges of the outer transverse webs of the hollow profiles to be connected can be bent and deep-drawn by stamped depressions around the recess of the straight connector, which delimits both sides and in particular extends over the entire width of the straight connector.
- Sealing compound can therefore either be provided beforehand on the straight connecting piece, or it can be injected subsequently after the connection and in particular the attachment of the panes of an insulating glass pane.
- a sealing process can be carried out after the connection, in which the sealing compound can expediently penetrate through the opening formed on the outside in the region of the colliding crossbars by deep-drawing and can seal any remaining cavities.
- the sealing compound can expediently penetrate through the opening formed on the outside in the region of the colliding crossbars by deep-drawing and can seal any remaining cavities.
- an increased thickness of the sealing compound is achieved in this area, so that a such a spacer frame allows a smaller thickness of the sealing compound and yet a required minimum thickness is achieved in the joint area.
- the ends of the crosspieces - when connected to the straight connector - can be deep-drawn so that the distance and / or remaining distance between them is small and in particular smaller than the dimensions of filled or to be filled desiccant bodies.
- this enables sufficient compression and connection of the hollow profiles with the straight connection piece to be achieved and, on the other hand, that sealing and / or sealing compound penetrate into the hollow profiles and into the straight connection piece, but desiccant bodies or grains present there cannot escape.

- the recess 4 is delimited by steeply sloping walls 8 which have relatively sharp edges on the mutually facing sides and which extend over the entire width of the straight connection piece 1 and thus a stable and rigid arrangement in the region of the recess 4 result.
- the corresponding bending and deformation of the transverse webs 3 takes place practically over their entire width and also includes the transition webs 6, because the walls 8 mentioned - as already mentioned - adapt to the cross-sectional profile of the hollow profiles 2, for example according to FIG Have corresponding bevels 8a at the ends.
- Spacer frames, in which such a straight connector 1 is used must either contain a desiccant before they are plugged into the straight connector 1 or be filled from one or both sides up to the straight connector 1 with desiccant.
- the recess 4 is delimited by steeply falling end faces 9 of webs 10 leading to it, in which case the webs 10 running in the longitudinal direction of extension of the straight connection piece 1 are formed in that they form the U-legs of one Straight connecting piece 1 with a U-cross section, which can be bent and folded, for example, from sheet metal, as is particularly clear from FIGS. 34 and 36 together.
- FIGS. 39 to 43 The same applies to the embodiment according to FIGS. 39 to 43.
- FIGS. 44 to 48 Another way to form the recess 4 and with Providing relatively sharp edges and steeply sloping boundaries is realized in the exemplary embodiment according to FIGS. 44 to 48 in that the recess 4 is delimited by transverse edge edges 11 of an opening 12, which in this case are in a U-crosspiece 13 of a straight connecting piece 1 are arranged, the U-transverse web 13 forms the back, as can be clearly seen in Figures 44 to 48, the U-transverse web 13 analogous to the transition webs 6 of the hollow profiles 2 also via transitions 14 with the down or with a finished insulating glass pane inwardly facing U-legs 15 is connected.
- an opening 12 extending over its entire cross-sectional extent can be provided in this U-crosspiece 13, which also also detects or passes through the transitions 14, in order in this case also to the outer crosspieces 3 of the hollow profiles 2 according to FIGS. 47 and 48 to be able to bend the aforementioned edge edges 11 inward and deep-draw.
- a tensile force can be exerted on the recess 4 of the straight connection piece 1 by the aforementioned deformation and deep-drawing process on the hollow profiles 2 to be connected, by means of which the end profiles of the hollow profiles are firmly pulled towards one another and fixed, so that together with in this area - Sealant to be brought a sealed joint of the two hollow sections 2 can be created, which also has a high strength.
- the embodiments according to FIGS. 1 to 24 and 25 to 33 are straight connection pieces 1, which can expediently be made of plastic or metal by injection molding or die casting.
- the other embodiments on the other hand, can expediently be bent from sheet metal, but could also be molded parts.
- parallel side walls 16 extending up to the middle depression 4 in particular Fig. 1 ff.
- FIGS. 13 and 14 can lead to a further reinforcement of the positive connection between the hollow profiles 2 and the straight connector 1. If such end closures 18 and also continuous walls 8 are not present in the region of the depression 4 as in the exemplary embodiments according to FIGS. 25 ff., The side walls 16 mentioned can be formed or replaced by the webs 10 running in the longitudinal direction.
- the recesses 17 continue into the recess 4 and form a continuous channel, closed in the use position by the hollow profile 2, in particular on the back of the respective straight connection piece 1, but this also applies if according to the 44 to 48, the corresponding recess 17 arranged between the side walls 16 or the U-legs 15 forming these side walls is arranged and opened on the side of the straight connector 1 facing away from the back.
- This closed channel thus leaves a passage and passage for drying agent granules 19, as is indicated in FIGS. 31 to 33 and 35 to 38.
- one of several hollow profiles 2 with the help of such Straight connector 1 composite hollow profile before or after it is bent to a spacer frame with desiccant bodies 19, which then get into all sections of such a hollow profile despite the straight connector 1.
- the straight connection piece with its cross section is adapted to a hollow profile 2 with parallel side webs 20 and two spaced cross webs, namely the outer cross web 3 and an inner cross web 21, in which in the position of use between the outside cross piece 3 and the side pieces 20, the already mentioned, something oblique or convex or concave transition webs 6 are provided.
- the depth of the recess 4 corresponds approximately to or exceeds the cross-sectional depth of the hollow profile 2 bridged by the transition webs 6.
- the transition webs 6 in the area of the joint can be deformed and drawn in a little inward and downward during deep drawing.
- side webs 20 can protrude beyond the inner crossbars 21 through extension webs 22 (FIGS. 10 to 24) in order to form a correspondingly wide side contact for the panes of insulating glazing to be kept and sealed at a distance.
- the width of the recess i.e. its dimension in the longitudinal direction of the straight connector 1, is about twice as large as its depth or slightly larger, so that the bent and deep-drawn parts of the outer crossbar 3 find enough space and with their ends possibly a little above of the bottom 4a of the recess 4 come to rest.
- the straight connection piece on its underside facing away from the recess 4 has run-up bevels 25 extending to a central notch 24, the underside notch 24 having one on the end faces to be connected the hollow sections 2 can accommodate the existing cutting burr in the position of use, which even forms a catch with this notch 24.
- the ramp slopes 23 on the top and ramp slopes 25 on the bottom of the straight connector are each offset laterally from each other relative to the longitudinal center of the straight connector 1. This helps to align the hollow profiles 2 to be connected and to adapt them to one another with their cross sections.
- Walls 8 in their upper edge area at least one, in
- Sealant is displaced or filled later. It can then be avoided by these grooves 26 that air nests remain within the sealant, which can lead to leaks over time.
- At least the depression 4 is at least partially filled with a sealing compound 27 , before the straight connector and the hollow profiles 2 are put together.
- the mutually facing edges of the outer transverse webs 3 of the hollow profiles 2 to be connected can be pressed into this sealing compound 27 during deep drawing, which leads to a corresponding displacement of the sealing compound 27, which is shown particularly clearly in FIG. 23.
- Fig. 22 and 23 it is shown that in the bottom 4a of the recess 4 at least one channel 29 leading to the underside and on the underside a flat depression 30 are provided, into which the channel 29 opens, so that when the sealant 27 is displaced it also passes through the channel or channels 29 into this depression 30 on the underside and there the seal between the straight connector 1 and the hollow profiles 2 is further improved on the inside, that is to say leads to a secure seal especially at the joint of the hollow profiles 2.
- This depression 30 extends over the entire width of the straight connector 1 and can optionally extend to the sealant which is pressed into the flat lateral extensions 21.
- the straight connection piece 1 allows different manufacturing methods, which nevertheless results in a straight connection piece 1, on which advantageously ter way, the mutually facing ends of the outer crosspieces 3 deformed inward and can be deep-drawn in order to pull the two hollow profiles 2 to be connected to each other and thereby more firmly.
- the straight connector 1 can consist of metal or die-cast or of hard plastic, insofar as it relates to the exemplary embodiments according to FIGS. 1 to 33.
- it can also consist of a bent sheet metal part, as shown in FIGS. 34 to 48 and which will be explained in more detail below.
- the straight connecting piece 1 designed as a sheet metal part has an approximately U-shaped cross-section, which in turn is adapted to the inner cross-section of the hollow pure profile 2, and therefore also takes into account the transition webs 6.
- the U-legs have at their ends adapted to the transition webs 6 the recess 4, so that this straight connector 1 also allows the passage of desiccant 19.
- the area of the depression 4 according to FIGS. 39 to 43 can in turn be filled with sealing compound 27 which, when the mutually facing ends of the transverse webs 3 of the hollow profiles 2 are deformed, into the depression 4 (FIGS. 42 and 43) something is displaced and the seal improves.
- desiccant must be filled in from the sides or be present from the start in the hollow profiles 2, into which this straight connector 1 is then inserted at the end.
- the straight connecting piece 1 which is designed as a sheet metal part, also has a U-shaped cross section, which is also adapted to the inner cross section of the hollow profile 2 and also its transition webs 6, as has already been mentioned, the U- Transverse web 13 has the recess 4, which is punched out, for example.
- the U cross-section between its U-legs 15 in a region projecting beyond the recess 4 on both sides in the longitudinal direction by a seal 31, for example a foam seal, and one between the U-crosspiece 13 and this seal 31 arranged plastic-elastic sealing compound 27 filled, which in turn is displaced into the recess 4 when the ends of the outer transverse webs 3 of the hollow profiles 2 are deformed and the tightness is improved. It can be seen how desiccants can be filled in from both sides up to this sealed area of the recess 4 from both sides.
- a seal 31 for example a foam seal
- the method for connecting the end faces of two hollow profiles 2 with the aid of one of the straight connecting pieces 1 described above, which can be inserted or inserted approximately halfway into the end faces of the hollow profiles to be connected, is largely similar in all cases. After pushing the hollow profiles 2 onto the straight connection piece 1 or vice versa after inserting the hollow profile 1 into the end faces of the hollow profiles 2 to be connected, these are deformed on their outside and pressed in such a way that a form fit is created with the straight connection piece 1.
- transverse webs 3, which form the outer sides of the hollow profile 2, of the mutually facing end faces of the hollow profiles are simultaneously deformed and pressed into a depression 4 extending over the entire width of the straight connector 1, and also somewhat in their deformation region lengthened or deep drawn. It is therefore not only a slight indentation, but rather a considerable deformation, through which at least transition regions or transition webs 6 are also somewhat deformed due to the depression extending over the entire width, so that bulging on the side surfaces is avoided. Accordingly good the glass panes to be placed on the side webs 21 - with extension webs 22 - can be sealed.
- the mutually facing edges or ends of the transverse webs 3 of the hollow profiles 2 to be connected are bent around sharp edges on the edge of the recess 4 and thereby deep-drawn.
- the areas of the crossbars 3 to be deformed are each bent and deep-drawn in their edge area around the walls 8 or end faces 9 of webs 10 leading to the depressions 4, i.e. around those parts or areas which extend on the outside of the straight connector 1 Limit recess 4 forming the channel to the side.
- the mutually facing ends of the outer transverse webs 3 can be pressed during deep drawing into a sealing compound 27 located in the recess 4 and the sealing compound 27 can thus be behind the bent regions of the transverse webs 3 and / or between the straight connecting piece 1 and the side webs 20 or that of the deformation facing away inner crossbar 21 of the hollow profile 2 are displaced.
- drying agent granules 19 can also be filled in through the connection area, i.e. which can pass through the correspondingly designed straight connecting piece 1, for example according to FIGS. 25 to 27, the ends of the transverse webs 3 can be deep-drawn so that the between arising and / or remaining distance is small and in particular smaller than the dimension of filled or to be filled desiccant bodies 19, so that they cannot emerge from the opening created by deep drawing between the crossbars of the hollow profiles 2 to be connected.
- a sealing layer 32 can be applied to the outside of the hollow profiles 2 after pressing with the straight connector 1, before or after the application of a sealing compound, which layer partially extends into the opening formed between the deep-drawn parts of the crosspieces 3 penetrates and then receives a correspondingly large layer thickness at this particularly well-sealed point, so that the thickness of this sealing layer 32 can be kept smaller in the remaining areas.
- an inward depression is formed by deep-drawing the mutually facing ends of the transverse webs 3 of the hollow profiles 2 to be connected on the outside of a spacer or spacer frame produced in this way, because then the sealing compound 32 is at this point receives a correspondingly large thickness through which air or moisture can no longer get through.
- This sealing layer 32 can either penetrate directly into the corresponding opening and also into the recess 4 of the straight connector 1, as is shown in FIG. 16. However, it can also interact with a sealing compound 27 already provided there, as shown, for example, in FIG. 24 or also FIG.
- the straight connector 1 is used for partial, preferably approximately half engagement in the end faces to be connected to each other and open on these end faces hollow sections 2, which serve to form a spacer frame or as a spacer for insulating glass panes.
- the cross section of the straight connection piece 1 fits into the inner hollow cross section of the hollow profile 2 and is at least partially designed and contoured accordingly in order to partially support and stiffen the hollow profile 2 in the area of the joint.
- the straight connector 1 On its back facing the outer crosspiece 3 of the hollow profile 2 in the position of use, the straight connector 1 has in its central region a depression 4 which extends over both sides of the joint of the hollow profiles 2 and into which the mutually facing ends of the outer crosspiece 3 of the hollow profile 2 can be deformed.
