Abstract

The sealing strip is extruded in one process using an elastic material for the main support and a foam material for the seal. The strip has a backing (120) of elastic material and with shaped grip lips (11,12) at the bottom. The top section holds the hollow profile foam strip which is clad in an outer coating of elastic material. The foam and the hollow space have a large compression facility to cover the sealing gaps. The lower part of the foam is attached to the support strip by a section (25) which thickens towards the support strip. The support strip has a bump strop strip (221) on the inside of the hollow space. Both materials are extruded together.

Description

The invention relates to a strand seal for building windows, building doors or like.

In the case of string seals, which are used, for example, to seal a window sash against a window frame or to seal a door leaf against a door frame have always been a major problem in that such string seals over time certain appearances of Are subject to material fatigue. Depending on the chosen areas of application such string seals can cause significant climatic fluctuations, such as large temperature differences are subject to what has so far led to that for the strand seals used material tired over time and hence the properties required for proper sealing function. this highly unpleasant phenomena were also encountered under normal ones Operating conditions, for example when using the strand seals inside of a constantly heated building.

Regardless of the material fatigue issue discussed above, the in Solid materials used in the past for strand seals are also considered some on the function of the thermal insulation as well as on the function of the sound insulation to be desired. One of the reasons for this was that the reset or Torsional properties of the solid materials used were not so good that always in was fully guaranteed that the strand seal even after intensive and / or sudden stress, for example as a result of increased closing pressure subsequent relaxation completely returned to its original shape. Consistency and stability of the functioning of the strand seal according to the state the technology was therefore at risk.

As a result, especially when the solid material of the strand seal has aged which are extremely relevant for the proper sealing function of the strand seal Resetting or torsion properties all in all unsatisfactory For example, could result in a reliable and dimensionally stable Attachment of the strand seal was no longer guaranteed. This often had one Removing the strand seal from a retaining groove in sections, so that the String seal could no longer fulfill its sealing or protective function and it to the undesired entry of wind, dirt, water or the like.

It also proved to be the case with those known from the prior art String seals as extremely disadvantageous that evenly thin walls could not be realized in practice. This is a very important aspect increased efforts in terms of material savings of significant Importance. In this context it should also be borne in mind that the Range of applications for strand seals increasingly selective and becomes more diverse, so that the aspect of the choice of wall thickness is one plays an increasingly important role.

The above-mentioned disadvantages and problems were also due to the rebate sealing profile for window sashes according to DE 296 07 982 U1, soft Rebate sealing profile with a sealing back made of hard rubber material trained groove cover lip and foot prongs as well as a closed sealing head made of soft rubber material with closed pores.

DE 89 07 191 U1 discloses an elastic strand seal for windows and doors or the like, which has a profile body with protective film, the Profile body and the protective film each made of a thermoplastic elastomer exist, the elastomer parts of which are fully cross-linked, by the However, elastomer parts of the other thermoplastic elastomer are separated are, wherein the two thermoplastic elastomers are different from each other are.

Regarding the relevant prior art for the present invention still on DE 43 24 645 A1 (see in particular column 5, lines 17 to 27) and to DE 295 09 733 U1 (cf. in particular page 12, line 34 to page 13, line 13) pointed out.

With regard to the production of foamed elastomers after the The preamble of claim 1 is also referred to US-A-5 089 193.

Based on the aforementioned shortcomings, the present invention has the object to provide a string seal that can be used both under normal operating conditions and optimal restoring or torsion properties even with increased stress due to increased closing pressure disclosed.

In this context, the properties of the present invention are additionally sought the strand seal both in terms of the function of the thermal insulation and in To improve the function of sound insulation.

Furthermore, the present invention aims to provide strand seals, their materials No signs of fatigue if possible, even with long-term use subject. This is also for use under extreme climatic conditions, such as large temperature differences.

The present invention is also based on the object of providing an extruded seal, that can be manufactured and processed continuously, inexpensively and in a way that conserves resources.

Finally, the present invention continues to increase in importance in the field of environmental protection in this context also a strand seal which is easy and fully recyclable, the latter aspect especially with regard to the inevitable production waste is to be fed into a solution.

These tasks are solved by a strand seal according to the preamble of claim 1, the elastomer both soft elastic segments high elasticity as well as hard, crystallizable segments less Has elasticity.

The strand seal according to the present invention discloses both under normal conditions of use optimal reset as well as with increased stress due to increased closing pressure or torsional properties.

Here, both in terms of the function of the thermal insulation and in terms of the function of sound insulation by the strand seal described above an optimization achieved.

Furthermore, the present invention provides an extrusion seal that self-seals practically no material fatigue occurs over many years of use. Should it go against expectations for example with significant climatic fluctuations, such as large temperature differences, But if there is a material murder, then this applies to the strand seal of the present invention within such narrow limits that the proper sealing and Protective function of the strand seal due to its always excellent elastic properties is practically not affected.

The fact that with regard to the process ecology is also particularly advantageous in the manufacture of string seals according to the present invention environmentally harmful by-products are produced, apart from one in the technical Practice inevitable minimum pollutant emissions practically not to air pollution comes.

In connection with these increasingly important efforts in the field of environmental protection it is therefore extremely worthy of appreciation that the strand seal according to of the present invention is easily and completely recyclable. This applies in particular to the waste that is inevitably produced during production and further processing, which is of course also has a positive impact on the costs of materials and disposal.

Furthermore, the present invention allows not only a continuous manufacturing process and a similar processing of the strand seal in particularly cost-effective and resource-saving way; rather it has turned out to be a particularly surprising and for those familiar with the prior art In no way predictable feature of the present invention emphasized that the material properties of the String seal can be controlled and selectively adjusted in an excellent manner can. Examples are the setting of such important material parameters such as density and / or hardness. The process parameters are Interestingly, this is aimed only at foaming, not at the Vulcanization.

Finally, those skilled in the art will appreciate the present invention know that the profile design of the strand seals according to the present invention if necessary, optimized using data processing technology can be ensured, which ensures high flexibility in production.

It goes without saying that all of the aforementioned aspects of both the Manufacturing depth as well as the width of the product range of strand seals according to benefit the present invention, especially since the technique of Foaming allows a much larger selection of usable materials. in the In connection with this, it is also recognized by the person skilled in the art, for example be that in the present invention also a thermoplastic corner gating is possible; it was precisely the aspect of corner gating that presented the specialist in connection with string seals in the past, sometimes only very much difficult to solve problems.

In an advantageous embodiment, the strand seal is a sash rebate / roll-over seal with the features of the invention set out below, which can be implemented independently of one another and / or in combination with one another. According to a preferred embodiment, the sash rebate / rollover seal accordingly has in particular:

a) a foot-side holding section with at least one holding lip for anchoring the sash rebate / rollover seal in a holding groove and

b) a head-side sealing section, which connects to the holding section via a profile back, and a contact wall opposite the profile back, a head-side connecting wall located on the side of the sealing section facing away from the holding section, connecting the profile back and the contact wall, and a connection side facing the holding section of the sealing section, which connects the profile back and the contact wall, has a foot-side connecting wall, at least one closed hollow profile being delimited by a section of the profile back, by the head-side connecting wall, by the contact wall and by the foot-side connecting wall, the profile back consisting of solid material and with the sealing section consisting of foamed material is co-extruded.

The sash rebate / overlap seal according to the present invention is disclosed both under normal conditions of use and under increased stress optimal reset or torsion properties due to increased closing pressure.

Here, both in terms of the function of the thermal insulation and With regard to the function of sound insulation by the above Sash rebate / rollover seal achieved an optimization.

The present invention further provides a sash rebate / overlap seal ready, with almost no wear even with long-term use Material fatigue. Contrary to expectations, it should be considerable climatic fluctuations, such as large temperature differences, yes If material fatigue occurs once, it will stick to the sash rebate / rollover seal according to the present invention within such narrow limits that the proper sealing and protective function of the sash rebate / roll-over seal practically not due to their always excellent elastic properties is affected.

The fact that with regard to the process ecology in the manufacture of sash rebate / overlap seals produced no environmentally harmful by-products according to the present invention apart from one that is inevitable in technical practice Minimal pollutant emissions practically do not result in air pollution.

In connection with these increasingly important efforts on the In the field of environmental protection, it is therefore to be assessed as extremely that the sash rebate / rollover seal according to the present invention is simple and is completely recyclable. This is especially true for those in manufacturing and Processing inevitable waste, which is natural also makes a positive impact on the cost of materials and disposal.

Furthermore, the present invention does not only allow continuous Manufacturing process and a further processing of the sash rebate / rollover seal in a particularly resource-saving manner; rather it has as a particularly advantageous feature of the present invention, that the material properties of the sash rebate / rollover seal through the extrusion process controlled and selectively adjusted in an excellent manner can. Examples are the setting of such important material parameters such as density and / or hardness. The process parameters are Interestingly, this is aimed only at foaming, not at the Vulcanization.

Finally, those skilled in the art will appreciate the present invention know that the profile design of the sash rebate / overlap seals according to the present invention optionally using data processing technology means can be optimized, resulting in a high Production flexibility is guaranteed.

It goes without saying that all of the aforementioned aspects of both the Manufacturing depth as well as the width of the product range of sash rebate / overlap seals according to the present invention, especially since Technology of foaming a much larger selection of usable Allows materials. In connection with this, it is used by the expert For example, it can also be recognized that in the present invention, about one thermoplastic corner gating is possible; just the aspect of corner gating provided the specialist in connection with sash rebate / overlap seals in the past it was sometimes very difficult to solve Problems.

Should the sash rebate / rollover seal according to the present invention in are particularly inventive, is one embodiment preferred, in which the wall thickness of the foot-side connecting wall towards Profile back increases. This can prevent dirt, water or the like between the edge of the holding groove at which the free end of the holding lip (s) is present, and the sealing section of the sash rebate / rollover seal reliably should be avoided, whereby it should be noted that the holding groove is generally of Contamination of any kind is to be kept in order to function properly to ensure the sash rebate / overlap seal.

This is the case with the sash rebate / rollover seals known from the prior art in addition to the at least one retaining lip, not seldom another additional lip provided that the transition area of the Haltutrandes covers. In this context, however, problems arise insofar as straight this cover lip for frequent and / or heavy use of the sash rebate / overlap seal, for example with increased closing pressure, no longer in their intended position to cover the Haltutrandes remains, but is deformed so that it can no longer develop its effect, which in In extreme cases, the sash rebate / rollover seal only has a limited function leads. Unwanted faults or a detachment of the The holding section from the holding groove can then often no longer be avoided.

The preferred technical measure that the wall thickness of the foot Connecting wall increases towards the profile back, becomes effective Way ensures that the foot-side connecting wall in any case in their Transition area to the profile back or in its transition area to System wall when the sash rebate / overlap seal is anchored in the retaining groove and keeps the transition area of the retaining edge stable in shape.

In this context, the person skilled in the art will consider it an option essential to the invention appreciate that the sealing section of the sash rebate / overlap seal further than the sash rebate / rollover seals known from the prior art can extend in the direction of the holding section, so that also in combination with the increasing wall thickness a full and full surface The connection wall on the foot side at the stop edge is assured.

For this purpose, the connecting wall on the foot side points straight in the holding section facing transition area to the profile back one compared to the other Wall thickness on significant thickening, which is the anchoring of the holding section in the Holding groove gives high strength and stability as well as a snug fit of the Sash rebate / overlap seal with optimal sealing effect guaranteed.

Although a convincing function of the object according to the present Invention through the design of the sash rebate / roll-over seal and / or is guaranteed by the selected material, it proves itself in the Manufacturing and processing as advantageous, although the holding section with the at least one retaining lip consists of solid material.

This solid material is preferably elastic and practical not foamed at least in sections and / or at least in places. in this connection Shore hardnesses are used for the solid material in operational practice range from about Shore-A-60 to about Shore-A-80 and preferably on the order of about Shore-A-70.

If you also want the present sash rebate / rollover seal in particular educate inventive way, it is recommended that the head Connecting wall, the system wall and / or the foot-side connecting wall to form foamed material.

The use of foamed material for the head-side connecting wall, for the contact wall and / or for the foot-side connecting wall offers both under normal conditions of use as well as with increased stress as a result increased closing pressure, optimal reset or torsion properties. Of further is both in terms of the function of the thermal insulation and in With regard to the function of sound insulation through the use of foamed Optimized material.

To the foamed material with effective protection against contamination to provide any type, according to a particularly essential to the invention Development of the present invention, the head-side connecting wall Contact wall and / or the foot-side connecting wall at least in sections and / or at least in places on an outer wall made of solid material type described above. This outer wall is what its thickness and its As far as application is concerned, at least in sections and / or at least in places in Formed an outer skin and can depend on the intended application be interrupted at least in sections and / or at least in places.

In particular in the corner and / or in the edge areas, the outer wall can according to an advantageous embodiment of the present invention at least in sections and / or at least in places in the form of a reinforcement, preferably in the form of a reinforcement wall and / or in the form of a Reinforcement strand, be formed.

With regard to the material used, a practical embodiment will turn out to be prove advantageous in which the solid material at least in sections and / or is at least in places considerably harder than the foamed material. Here are according to a particularly inventive development, the existing solid material Parts of the sash rebate / roll-over seal with those made of foamed material existing parts of the sash rebate / rollover seal connected by coextrusion.

To better, more permanent and more stable anchoring of the holding section in the To ensure a retaining groove, the retaining lip is in accordance with a preferred one Embodiment of the present invention towards its free end Sealing section inclined. As a result, the retaining lip can be seen in the Claw the walls of the holding groove.

Here are in the practical execution of the sash rebate / rollover seal according to the present invention advantageously two retaining lips are provided, which increases the likelihood of the holding portion coming out of the Retaining groove is significantly reduced because even in the practically non-occurring In the event of failure of the holding action of one of the holding lips, the other still holds Effect.

An unexpectedly strong anchoring of the sash rebate / overlap seal according to the present invention in the retaining groove can be achieved in that the two Retaining lips have a different length. In this way, on the one hand Bumps and unevenness, for example, in terms of width and the same holding groove can be compensated for, on the other hand, this means flexibility in relation to the possible uses of the sash rebate / rollover seal increased than these designed for holding grooves of different widths and shapes and can be used.

Here, an embodiment has proven itself in which the sealing section continues remotely located retaining lip shorter than that closer to the sealing portion Holding lip is, the length difference advantageously in one Order of magnitude, in which one of the retaining lips by about 0.1 millimeters to about 0.3 millimeters, preferably about 0.2 millimeters, is shorter than the other one Retaining lips.

According to a particularly advantageous embodiment of the present invention the profile back extends approximately straight from the foot side Holding section over the head-side sealing section, so that a full and full area Correction of the profile back on the respective part to be sealed is guaranteed.

To have a special stabilizing effect with regard to the anchoring of the To achieve holding section in the holding groove, the profile back has in the area of Holding section preferably a greater thickness than in the region of the sealing section on.

In this context or independently of this, a Embodiment prove to be useful in which the profile back in Transition area from the holding section to the sealing section towards a tapering Form that has to a certain extent the widening of the foot Can pick up and compensate the connecting wall to the profile back.

According to a preferred development of the present invention, at least a hollow profile in its interior at least one damping element that especially in the event of a violent closing pressure, i.e. a large one Force on the system wall and therefore also on the head side Connecting wall as well as striking the connecting wall on the foot side Contact wall on the back of the profile insofar as it prevents the movement of the contact wall dampens or cushions. This will result in excessive mechanical stress the components of the sealing portion prevented in a reliable manner, whereby it to meet the above-mentioned damping or cushioning effect as appropriate proves to arrange the damping element on the profile back.

In addition to the damping element, the elements required to fulfill the above-mentioned damping or cushioning effect to give desirable mechanical strength the damping element advantageously made of non-foamed solid material.

Regardless of whether a rather weak or a strong closing pressure on the Sealing section of the sash rebate / rollover seal is proven "as Starting position "for the sealing section an arrangement as recommended, in which the profile back and the wall in the relaxed state slightly inclined to each other stand. This allows different types of stress constellations in be compensated in an elegant and flexible manner.

This also applies to a preferred embodiment of the present invention, in which the head-side connecting wall is V-shaped, the tip of the V-shape the head-side connecting wall expediently into the interior of the hollow profile has. This will result in the compression of the sealing portion due to If there is a closing pressure, a concertina effect, so to speak caused, whereby the force introduced is adequately absorbed can be. Furthermore, it is also used to absorb the force introduced Available path enlarged.

As already stated at the outset, the present invention relates to their flexibility is characterized, among other things, by the fact that they have one or more hollow profiles having. According to a preferred embodiment, a hollow profile is in the Provided frame of the sealing section, so the system wall can be relaxed Condition in the transition area to the head-side connecting wall slightly outwards be arched.

The damping element is then independent of this or in connection with it advantageously arranged approximately in the middle of the profile back, which ensures optimal Damping or cushioning even with extreme stress on the sealing section is ensured.

According to a preferred embodiment, two hollow profiles are now in the frame provided the sealing section, so the contact wall in the relaxed state easily be arched inwards.

To divide the sealing section into the two hollow profiles runs according to one particularly inventive training between the profile back and the Contact wall a web through which the sealing section also provides excellent stability very heavy use is given. Such an increase in stability plays a role as an option essential to the invention, especially if the Sealing section of the sash rebate / rollover seal in the context of the solution according to the present invention extends relatively far in the direction of the holding portion, so that also in combination with the increasing wall thickness a rich and full-surface contact of the foot-side connecting wall at the retaining edge guaranteed is.

Here, the web can develop its stabilizing effect in particular when he connects the back of the profile with the contact wall approximately in the center, because then a particularly uniform application of force and distribution of force can be achieved. To For this purpose, an embodiment can also be preferred in which the web is below an inclination runs from the profile back to the contact wall, the web then from Profile back to the contact wall advantageously runs in a direction that is inclined away from the holding section.

The manufacture of the has proven to be particularly free of complications Sash rebate / overlap seal according to the present invention when the The web expediently has a thickness which is approximately the thickness of the head-side Connecting wall or approximately corresponds to the thickness of the contact wall, and / or if the bridge is made of foamed material.

Finally, in relation to the embodiment with two hollow profiles on one advantageous embodiment pointed out, in which the holding section closer located hollow profile smaller than that located further away from the holding section Is hollow profile. Regardless of this or in addition to this, this can Damping element inside that further away from the holding section Be arranged hollow profile.

The features of the invention set out above, which are independent can be realized from one another and / or in combination with one another on the advantageous embodiment, which is a strand seal Sash rebate / roll-over seal deals.

In the figure 2 strand seal shown here is a sash seal, the a foot-side holding section 210 with a foot web 2101, the two holding lips 2102, 2103 for anchoring the strand seal in a retaining groove, and a head-side sealing section 220 with a closed hollow profile 2201, the has a profile back 2202.

As can be seen from the illustration in FIG. 1, this is in the installed state closed hollow profile 2201 with its profile back 2202 permanently on one of the parts to be sealed against each other and with its profile back 2202 opposite wall 2203 only temporarily on the other of the parts to be sealed against each other.

FIG. 2 also shows that the closed hollow profile 2201 in its inside is a semi-circular support part filled with material 2204. This shape ensures high restoring forces at an excessive extensive closing movement and thus securely fixes the door leaf, for example or the window sash in a precisely defined position, so that a rattling for example, the door leaf or the window sash due to wind is avoided.

The support part 2204 is significantly smaller than the closed hollow profile 2201 and is arranged on the inside of the profile back 2202 approximately in the middle, so that the support part 2204 has an outer surface with the closed hollow profile 2201 has in common what is particularly cheap in terms of manufacturing technology.

The support part 2204 points in the direction of the distance line between the Profile back 2202 and the wall 2203 a dimension of about half the Distance between the profile back 2202 and the contact wall 2203 in the unloaded Condition on. This causes a particularly favorable spring action of the support part 2204, since the closed hollow profile 2201 about half of its size can be compressed without the support member 2204 a corresponding Undergoes compression. Only if the closing movement is too violent or if If an excessive closing force occurs in wind power, the support part 2204 additionally deformed to allow the spring force to increase rapidly and a hard one Avoid hitting the parts.

On the inside of the wall opposite the support part 2204 is a receptacle 2205 arranged, which partially encloses the support member 2204 under closing pressure. The receptacle 2205 is here in FIG. 2 approximately in the middle of the contact wall 2203 is arranged and takes a U-shaped shape, the maximum height of the two legs 2205a, 2205b of the U-shaped receptacle 2205 in the direction of Distance straight line between the profile back 2202 and the contact wall 2203 a Dimension of about a fifth of the distance between the profile back 2202 and the system wall 2203 has in the unloaded state.

From Figure 2 it can be seen that the footbridge 2101 has a greater thickness than that Has profile back 2202, the thickness of the foot bridge 2101 in the transition region to the profile back 2202 is largest. It is worth mentioning in this context nor that the profile back 2202 is approximately straight from the holding section 210 extends over the sealing portion 220.

The profile back 2202 and the contact wall 2203 are in a relaxed state slightly inclined to one another, the contact wall 2203 being curved slightly inwards, so that the closed hollow profile 2201 in a relaxed state in its rough outline in has approximately the shape of a trapezoid, the profile back 2202 and the System wall 2203 the longer sides of the trapezoid and two to the profile back 2202 and to the contact wall 2203 transverse walls 2206, 2207 the shorter sides of the trapeze.

In the transition area between the holding section 210 and the sealing section 220 the footbridge 2101 has a cover lip 2104, which is on the Holding section 210 facing wall 2207 at a height of about one third, based on the total length of the lip 2104 and measured from end of the cover lip 2104 attached to the profile back 2202, with the cover lip 2104 is connected. Here, it faces the holding section 210 facing wall 2207 in the area in which they in the Cover lip 2104 opens, a curvature on that of the curvature of the curve 2208 in the transition area between the system wall 2203 and the on the Holding section 210 facing wall 2207 is opposite, so that wall 2207 takes the form of an S curve.

The one of the two on the side facing away from the holding section 210 for Profile back 2202 and walls 2206, 2207 which run transversely to the contact wall 2203 is V-shaped in Figure 2, with the tip of the V-shape inside the closed Has hollow profile 2201. Here it can be seen from Figure 2 that on the Holding section 210 facing away from wall 2206 longer than that on is the wall 2207 located on the side facing the holding section 210.

FIG. 2 further shows how those facing away from the holding section 210 Side located wall 2206 at the end facing the contact wall 2203 in a Sealing lip 2209, 2210 passes over. This sealing lip 2209, 2210 is relaxed Condition at an approximately right or slightly larger angle to the end of the on the wall 2206 located on the side facing away from the holding section 210 and corresponds in length and width roughly the corresponding dimensions of one of the two Halves of the wall located on the side facing away from the holding section 210 2206th

The figure 2 can also be seen that the inside of the on the Holding section 210 facing away wall 2206 in the transition area to the sealing lip 2209, 2210 has a notch 2211, which acts as a predetermined kink acts. Here, the side facing the closed hollow profile 2201 is the Sealing lip 2209, 2210 at a distance of about a third, based on the Total length of the sealing lip 2209, 2210 and measured from the free, unsecured end the sealing lip 2209, 2210, connected to the contact wall 2203, the outer transition area between the contact wall 2203 and the sealing lip 2209, 2210 has a notch 2212, which acts as a predetermined kink and larger than that Notch 2211 in the inner transition area between which on the Holding section 210 facing away from wall 2206 and the sealing lip 2209, 2210.

While the first exemplary embodiment, shown schematically in FIG Strand seal according to the present invention from any outer wall Has solid material, shows schematically in the figures 2b and 2c illustrated embodiments of a strand seal according to the present Invention the side of the profile back facing away from the closed hollow profile 2201 2202 sections of an outer wall 2301 made of solid material.

The outer wall 2301 in FIG. 2b has a Shore hardness that is less than is about Shore-A-80. In contrast, the outer wall 2301 in FIG. 2c has one Shore hardness greater than about Shore-A-80 so that the outer wall 2301 in 2c as reinforcement of the strand seal in the area of the profile back 2202 is trained. This reinforcement causes the strand seal to be largely hers Keeps shape so that a tight fit on the sash rebate is guaranteed. Through the Guaranteed dimensional stability of the strand seal is also ensured that a The passage of air or moisture is practically avoided.

The outer wall 2301 extends here both in FIG. 2b and in FIG. 2c to the foot end of the holding section 210 and ends at a certain distance to the head end of the profile back 2202.

It can also be seen from FIGS. 2b and 2c that the head end of the Profile back 2202 has an outer wall 2302 made of solid material.

The outer wall 2302 in FIG. 2b has a Shore hardness that is less than is about Shore-A-80. In contrast, the outer wall 2302 in FIG. 2c has one Shore hardness that is greater than about Shore-A-80, so that the outer wall 2302 in Figure 2c as a reinforcing strand at the head end of the profile back 2202 is trained. This reinforcement causes the strand seal to be largely hers Keeps shape so that a tight fit on the sash rebate is guaranteed. Through the Guaranteed dimensional stability of the strand seal is also ensured that a The passage of air or moisture is practically avoided.

Both in FIG. 2b and in FIG. 2c there is between the outer wall 2301 and the outer wall 2302 material that is much softer than the material of the Outer wall 2301 and than the material of the outer wall is 2302.

In FIG. 2b the side facing away from the closed hollow profile 2201 also has the Contact wall 2203 an outer wall 2303 made of solid material. The outer wall 2303 ends here at a certain distance from the head end of the contact wall 2203.

As already indicated above, the closed hollow profile 2201 in relaxed state in the transition area between the system wall 2203 and the there is a wall 2207 on the side facing the holding section 210 outward curve 2208, which in Figure 2b an outer wall 2304 Has full material.

Also the side facing away from the closed hollow profile 2201, which is on the Wall section 2206 facing away from the holding section 210 has an outer wall 2305 made of solid material.

The outside of the sealing lip 2209, 2210 also has an outer wall 2308 Full material on.

While the exemplary embodiments shown schematically in FIGS. 2b and 2c a strand seal according to the present invention only partially an outer wall 2301, 2302, 2303, 2304, 2305, 2308 made of solid material, has in the in Figures 2d and 2e schematically illustrated embodiments of a Strand seal according to the present invention the entire outside of the String seal an outer wall 2301, 2302, 2303, 2304, 2305, 2306, 2307, 2308 made of solid material when you move from a small area between the Outer wall 2301 and the outer wall 2302, in which there is material that much softer than the material of the outer wall 2301 and than the material of the Outer wall 2302.

The outer walls 2301 and 2302 in FIG. 2d have a Shore hardness that is smaller than about Shore-A-80, whereas the outer walls 2301 and 2302 in Figure 2e have a Shore hardness greater than about Shore-A-80, so that in Figure 2e the outer wall 2301 as a reinforcement of the strand seal in the area of Profile back 2202 and so that in Figure 2e the outer wall 2302 as Reinforcement strand is formed at the head end of the profile back 2202. These reinforcements ensure that the strand seal largely retains its shape, so that a tight fit on the sash rebate is guaranteed. Guaranteed by the Dimensional stability of the strand seal is also ensured that air or air can pass through Moisture is practically avoided.

In any case, such a smooth outer wall 2301, 2302, 2303, 2304, 2305, 2306, 2307, 2308 the foamed material completed what on the one hand offers excellent protection against contamination and on the other hand a level, full and full surface contact of the strand seal on counter surfaces causes.

The strand seal shown in FIG. 2 is one for the two wings, for example double-leaf window without set timber and is preferably as follows processed:

The strand seal is in the holding groove of the window sash, starting for example inserted in the middle of the upper horizontal part of the casement. there brace the two retaining lips 2102, 2103 in the groove, and the groove is covered by the cover lip 2104. The strand seal is thus in the groove used that the system wall 2203 faces the weather side when the window is closed and rests on the window frame. The profile back 2202 lies flat on Sash rebate.

As soon as a corner of the casement is reached, the strand seal is sealed with a V-shaped rectangular miter cut, which is placed so that the tip of the V-shaped section near the one on the holding section 210 opposite wall 2206 is located. Then the strand seal can be cornered.

After this has been done at all four corners of the casement, the end will be cut accordingly, so that there is a total of a rectangular sealing frame results. So since the same strand sealing profile for all four sides of the window sash can be used is both quick processing and complete Sealing is guaranteed especially at the mitred corners.

As a result of that, for example, in the form of a reinforcement Outer wall 2301 (cf. FIGS. 2b, 2c, 2d and 2e) and through the example in FIG Form of a reinforcement strand formed outer wall 2302 (see FIGS. 2b, 2c, 2d and 2e) achieved reinforcement of the strand seal in the area of the profile back 2202, the strand seal also largely retains its shape in the area of the mitred corners Form, so that a tight fit on the wing rebate is guaranteed. Through the Guaranteed dimensional stability of the strand seal is also ensured that in the Miter corners the individual sections of the strand seal even without welding so close to each other that air or moisture penetration is practical is avoided.

The passive leaf of the double-leaf window becomes similar to the rope seal provided, with the exception that the vertical middle frame part against which the Active leaf strikes, is not equipped with the rope seal. The over three The strand seal running on the side of the passive leaf thus ends at the top and bottom vertical part of the passive leaf. While the strand seal of the vertical The middle area of the active leaf is full and sealing on the sash rebate of the vertical the corner areas do not find the middle frame part of the passive leaf Abutment, so that problems with strand seals according to the prior art have resulted.

In this context it is certainly worth mentioning, that the system wall 2203 with the inactive leaf against the frame of the Window is pressed. The window frame largely covers the contact wall 2203 and extends from the top of the strand seal to the rounding 2208 in Transitional area between the system wall 2203 and which is on the Holding portion 210 facing side wall 2207.

By pressing against the frame, the system wall 2203 becomes approximately parallel in the direction of the profile back 2202, which is on the Holding section 210 facing away from wall 2206 accordion-shaped merges and rounding 2208 in the transition area between the Contact wall 2203 and on the side facing the holding section 210 located wall 2207 inside out, so that they fill up as a sealing bead the edge of the frame sets.

The system wall 2203 is large and full, so that even a small one Closing pressure is sufficient to ensure a secure seal against drafts and water guarantee. With a further compression of the closed hollow profile The wall 2203 comes in 2201 by means of the U-shaped receptacle 2205 System to the support member 2204, so that the spring force of the entire strand seal abruptly increased and a complete compression of the strand seal is prevented. On the other hand, the support part 2204 is still soft enough to to avoid hard opening of the wing.

In this way, a precise positioning of the window sash is possible, because that Support part 2204 in cooperation with the U-shaped receptacle 2205 one counteracts further compression of the closed hollow profile 2201. Thereby it is surely avoided that the window rattles when there is a wind load.

Figure 3 shows a (greatly enlarged) cross-sectional view of a second Embodiment of a strand seal according to the present invention in relaxed state, the installation situation of which is shown in FIG. 1. In the figure 3 strand seal shown is a rollover seal that a foot-side holding section 310, which holds at least one holding lip 3101 Anchoring the strand seal in a retaining groove, a footbridge 320, the has a ridge 3201, and a head-side central section 330, of which an extension 3301 extends.

As can be seen from the illustration in FIG. 1, in the installed state Bridge 3201 permanently on one of the parts to be sealed against each other and that free end of extension 3301 only temporarily on the other of the against each other parts to be sealed, wherein at the free end of the holding lip 3101 Reinforcement strand 3102 is arranged.

It can be seen from FIG. 3 that the central section 330 essentially extends perpendicular to the footbridge 320, the central section 330 at least has a cover tab 3302 on the side facing the holding section 310 is arranged.

The curvature of the essentially U-shaped extension 3301 is designed that the free end of the extension 3301 in the opposite of the holding portion 310 Direction shows.

The third embodiment of a strand seal shown in FIG The present invention partially has an outer wall 4301 made of solid material. in the The sealing nose 4201, the cover lip 4202 and the free one are special in FIG End wall of the sealing section 420 provided with the outer wall 4301.

Figure 5 shows a (greatly enlarged) cross-sectional view of a fourth Embodiment of a strand seal according to the present invention in relaxed state. The strand seal shown in FIG. 5 has a head part 510 and a band-shaped foot 520 with two parallel outer surfaces, one of which one is provided as a fastening surface 5201. The foot part 520 is in this case a much harder material than the head part 510.

At the foot part 520 there is a lip 5202 in the immediate vicinity of the head part 510 formed, which extends approximately perpendicular to the plane of the foot part 520 and over the mounting surface 5201 protrudes.

The head part 510 which is circular in cross section in FIG. 5 is connected to the Foot part 520 connected via a connecting neck 530, which is inclined to the plane of the Foot part 520 extends so that the head part 510 is offset in cross section to the plane of the Foot part 520 in the direction away from the mounting surface 5201. The headboard 510 thus protrudes towards the counter-sealing part, so that the head part 510 is already in one relative comes into contact with the counter-sealing part at an early stage of the closing process. On this allows tolerances of the parts to be sealed against each other easily be balanced, which means that even with deviations from the standard size tight closure of the two parts to be sealed is guaranteed.

The fourth embodiment of a strand seal shown in FIG The present invention partially has an outer wall 540 made of solid material. in the In particular, the head part 510 is provided with the outer wall 540 in FIG. Of the connecting neck 530 further consists of the solid material of the outer wall 540.

If the protective paper is from this layer of pressure sensitive adhesive or from this double-sided adhesive tape 5203 is removed, the strand seal can be continuously on the desired edge a window frame or a casement can be attached where they alone finds a secure hold due to the pressure-sensitive adhesive property.

Figure 6 shows a (greatly enlarged) cross-sectional view of a fifth Embodiment of a strand seal according to the present invention in relaxed state. The strand seal shown in FIG. 6 has two band-shaped, over a predetermined breaking point. 650 interconnected foot parts 620, 670, each having two parallel outer surfaces, one of which is as Mounting surface 6201, 6701 is provided, and two at the two free ends of the foot parts 620, 670 arranged head parts 610, 660. The foot parts 620, 670 are made of a much harder material than the head parts 610, 660 manufactured.

The fifth exemplary embodiment of an extruded seal shown in FIG The present invention brings enormous advantages especially when it comes to Use of string seals for windows, doors or the like applies two Cut the sealing strips to exactly the same length, for example for the upper one Frame part and for the lower frame part of a casement. By the two Foot parts 620, 670 are connected to one another via a predetermined tear point 650, the cutting of a sealing strip does not require a separate work step; rather, the double strand is simply created with the help of the predetermined crack 650 Cut to length into two individual sealing strands.

On the foot parts 620, 670 is in the immediate vicinity of the head parts 610, 660, respectively a lip 6202, 6702 is formed, which is approximately perpendicular to the plane of the foot parts 620, 670 extends and protrudes over the mounting surfaces 6201, 6701.

The head parts 610, 660 which are circular in cross section in FIG. 6 are included the foot parts 620, 670 connected via a connecting neck 630, 680, which extends obliquely to the level of the foot parts 620, 670, so that the head parts 610, 660 in cross section offset to the plane of the foot parts 620, 670 in the direction away from the Fastening surfaces 6201, 6701. The head parts 610, 660 thus protrude opposite counter part, so that the head parts 610, 660 already in one relatively early stage of the closing process with the respective counter sealing part in Come into contact. In this way, tolerances of each other sealed parts can be easily compensated, which means that also at Deviations from the standard dimension a tight closing of the two parts to be sealed is guaranteed.

The fifth embodiment of a strand seal shown in FIG The present invention partially has an outer wall 640, 690 made of solid material. In particular, the head parts 610, 660 with the outer wall 640, 690 are in FIG Mistake. Furthermore, the respective connection neck 630, 680 consists of the Solid material of the outer wall 640, 690.

It should be mentioned in connection with the fifth shown in FIG Embodiment of a string seal according to the present invention still that the attachment surfaces 6201, 6701 each have a layer of pressure-sensitive adhesive or one Double-sided adhesive tape 6203, 6703 is provided, which enables the assembly of the strand seal is further facilitated. If the protective paper is from this layer of pressure sensitive adhesive or from this double-sided adhesive tape 6203, 6703 is removed, the strand seal continuously on the desired edge of a window frame or a casement be attached where they are safe due to the pressure-sensitive adhesive properties alone Stops.

The fourth and fifth embodiment of a shown in FIGS. 5 and 6 Strand seal according to the present invention provides not only in the case extremely satisfactory results when viewed over their entire area is completely enclosed between two flat stop surfaces to be sealed, but also when the string seal is attached to the edge of a support member should be such that the head part 510 or the head parts 610, 660 over protrude the edge of the support part, as is often the case, for example Sash rebate seals are the case.

In the fourth and fifth embodiment shown in FIGS. 5 and 6, one Strand sealing according to the present invention, however, will result in a retreat of the Head part 510 or the head parts 610, 660 from the counter-sealing surface as a result of missing back support and as a result of buckling prevents the lip 5202 or lips 6202, 6702 are formed, which are approximately perpendicular to Extend the level of the foot part 520 or the foot parts 620, 670 and over the Attachment surface 5201 or attachment surfaces 6201, 6701 protrude.

In this way, the head part 510 or the head parts 610, 660 bring the one proper sealing sufficient back pressure. The headboard 510 or the Headboards 610, 660 are therefore reliably supported even when the strand seal is mounted in the area of the edge of a support part. The assembly is accordingly by the fourth and fifth shown in Figures 5 and 6 Embodiment of a string seal according to the present invention facilitated because lip 5202 or lips 6202, 6702 form with the fastening surface 5201 or with the fastening surfaces 6201, 6701 an approximately rectangular receptacle, the edge of the support member, such as the edge of a casement, encloses.

As a result, the position of the strand seal is precise when it is attached to the support part defined, which not only facilitates the assembly of the strand seal, but the head part 510 or the head parts 610, 660 also provide uniform support Experienced. This prevents the head part 510 or the head parts 610, 660 can be caused to buckle by the system pressure of the counter-sealing part can, which could happen particularly easily if the strand seal over the Edge of the support part protrudes too far and thus too large a lever for the attacking investment staff.

Figure 7 shows a (greatly enlarged) cross-sectional view of a sixth Embodiment of a strand seal according to the present invention in relaxed state. The strand seal shown in FIG. 7 is in this case a door seal which has a holding section 710 on the foot side with a Footbridge 7101, the four retaining ribs 7102, 7103, 7104, 7105 for anchoring the Has string seal in a retaining groove, and a head-side sealing section 720 with a closed, with respect to the center line of the footbridge 7101 approximately symmetrically arranged hollow profile 7201, the one transverse to the footbridge 7101 base wall 7202 extending to both sides, two to base wall 7202 subsequent side walls 7203, 7204 and one of the side walls 7203, 7204 connecting connecting wall 7205, 7206, 7207.

It can be seen from FIG. 7 that the base wall 7202 consists of two parts that differ from one another Middle outwardly extending legs 7202a, 7202b, which is slightly in the Are angled against each other so that they are to the longitudinal direction of the foot bridge 7101st take an angle of slightly less than 90 degrees. If one this way designed strand seal is inserted into the retaining groove, the two will be different the middle outwardly extending legs 7202a, 7202b of the base wall 7202 elastically deformed so that they form a straight line. As a result of the elastic deformation are the two legs 7202a, 7202b of the base wall 7202 under pressure on the both edges of the retaining groove, so that there is a tight fit there Ingress of dirt or the like is reliably prevented.

The sixth embodiment of a strand seal shown in FIG The present invention partially has an outer wall 730 made of solid material. in the The side walls 7203, 7204 and the connecting wall are special in FIG 7205, 7206, 7207 provided with the outer wall 730.

FIG. 7 shows that two pairs of holding ribs 7102, 7103, 7104, 7105 are provided, the holding ribs 7102, 7103, 7104, 7105 to both sides of the footbridge 7101. By adding two pairs of Holding ribs 7102, 7103, 7104, 7105 are provided, which are arranged in an arrow shape are so that they cling to the type of barbs in the holding groove, the Seat of the strand seal further increased.

The connecting wall 7205, 7206, 7207 is less thick than the base wall 7202 and as the sidewalls 7203, 7204 and has three inclined ones Wall sections 7205, 7206, 7207, which in a relaxed state under a Angles of about 150 degrees to each other are made.

If in addition the middle wall section 7206 between the two roof-like wall sections 7205, 7207 towards the inside of the closed hollow profile 7201 is arched between the two Sealing levels not only included an air space that is excellent Soundproofing function fulfilled, since sound waves in this air volume are special be effectively damped, but it also makes it a particularly safe one Sealing function achieved with relatively large installation tolerances:

This configuration results in two on the head-side sealing section 720 Sealing surfaces, namely in the respective transition area between the roof-like Wall section 7205 or 7207 and the roof-like wall section 7205 on this or 7207 connecting middle wall section 7206.

If, for example, the sixth exemplary embodiment shown in FIG String seal according to the present invention is used for a door who has shifted the position of the door leaf over time, this ensures that at least one sealing surface comes into contact with the door leaf and the Performs the sealing function. If the door leaf is correctly positioned, however, the Seal in two levels on the door leaf, so that the intended, especially effective sealing is given.

FIG. 7 also shows that the wall sections 7205 and 7207, the are connected to the side walls 7203 and 7204 in a relaxed state with sidewalls 7203 and 7204 form an angle of approximately 120 degrees. Here, the two side walls 7203, 7204 run in the direction of the holding section 710 opposite end of the string seal at an angle of 1 degree to 10 Degrees towards each other. This has the advantage that the strand seal shown in Figure 7 the side walls do not bulge in this area when loaded.

Figure 7 shows that the transition area between the sidewalls 7203, 7204 and the connecting wall 7205, 7206, 7207 on the closed hollow profile 7201 facing side each has a notch 7208, 7209, which as Target kink acts.

FIG. 7 further shows that the transition area between the wall sections of the Connecting wall 7205, 7206, 7207 on the closed hollow profile 7201 facing side has two notches 7210, 7211, which serve as predetermined breaking points act and are of the same size.

The aforementioned notches 7208, 7209 and 7210, 7211 are in the areas arranged the string seal, in which a pressure build-up of the material takes place. Due to this arrangement of the predetermined kinks, the pressure build-up lies String seal in the loaded state in the optimal range, so that for example, the door closes easily.

Inside the closed hollow profile 7201 is on the inside of the base wall 7202 an approximately semicircular support part 7212 is arranged approximately in the middle thereof, which is much smaller than the closed hollow profile 7201, with an outer surface the closed hollow profile 7201 has in common and in the direction of Distance line between base wall 7202 and connecting wall 7205, 7206, 7207 a dimension of about half the distance between base wall 7202 and Connecting wall 7205, 7206, 7207 in the unloaded state. With this Support part 7212 in FIG. 7 is a closed cross section Pressure chamber.

The arrangement of such a support member 7212 is in response to the Strand seals are a common disadvantage to see strand seals either require a very high closing pressure or the sealing effect does not is completely satisfactory. If the string seal is made "too hard", it requires a high closing pressure. However, if the string seal becomes "too soft" executed, it can happen that when the door is closed carelessly or the closed hollow profile 7201 is completely squeezed together during wind loads is so that there is a hard impact of the door leaf on the door frame.

For this reason, there is one in the sixth exemplary embodiment shown in FIG String seal according to the present invention within the closed Hollow profile 7201 arranged a closed pressure chamber 7212 in cross section. Through this pressure chamber 7212, the closing pressure is as low as possible maximum sealing function guaranteed; nevertheless it becomes a perfect one Compression of the string seal and a correspondingly hard stop reliably avoided.

When a component is closed, for example a door, the Door leaf on the door frame first compresses the closed hollow profile 7201, which tired in the space between the two mutually movable parts invests.

If the two parts to be sealed against each other with further compression of the closed hollow profile 7201 over and above a certain setpoint are moved, the pressure chamber 7212 is compressed. The pressure chamber 7212 must be deformed. Because the pressure chamber 7212 is smaller than that closed hollow profile 7201, much greater forces are required for this, so that with a disproportionately high compression of the strand seal Spring force increases more quickly than with only slight compression. Thus the Blocking movement blocked without the parts hitting each other hard.

By making the pressure chamber 7212 much smaller than the closed hollow profile 7201, it is achieved that only in the last section of the closing movement Pressure chamber 7212 comes into operation, but then enters through pressure chamber 7212 the spring force increases very rapidly.

In addition, it should also be mentioned in this connection that the holding section 710 has at its free end a V-shaped notch 7106, the tip of which Sealing portion 720 has, with a pair of the holding ribs 7104, 7105 at the free End of the holding portion 710 is arranged so that the depth of the notch 7106 extends approximately over the thickness of the holding ribs 7104, 7105. It has shown that such a training has a particularly effective spring effect between the opposite holding ribs 7104, 7105 results in what - how explained below - has the consequence that the strand seal comfortably in a holding groove can be inserted.

When processing the sixth embodiment shown in FIG String seal according to the present invention, this with the holding portion 710 is pressed into a holding groove, the holding ribs 7102, 7103, 7104, 7105 deform elastically and the V-shaped notch 7106 is narrowed so that the holding ribs 7102, 7103, 7104, 7105 relatively easy in the Have the groove pressed in. The base wall 7202 lies on the two edges of the Keep the groove open and become more elastic towards the head end of the strand seal Deformation shifted so that the edition with a predetermined contact pressure he follows.

Since the sixth embodiment of a strand seal shown in FIG present invention is completely symmetrical, it can be in any of the two possible layers can be installed.
