Description

Field of the invention

The invention relates to a mounting cap for use in the assembly of hollow profile frame, such a mounting method and a unit of a mounting cap and a hollow profile corner connector.

State of the art

In the production of insulating glass composite windows so-called spacer frames are used to keep the individual disks of the composite against each other at a distance. Such spacer frames are typically made of hollow profile sections, which are interconnected to form the frame corners by means of so-called corner connectors. Such a corner connector typically consists of two legs which are arranged at an angle to one another and which are connected to one another in a thickened end region (opposite to the legs). The outer dimensions of the connector legs are adapted to the inner dimensions of the hollow profile sections, that the former can be inserted non-positively in the latter. Usually, the connector legs to improve the frictional elastic structures, such as herringbone arranged fins. The insertion of the connector legs in the hollow profile sections usually takes place until the end face of the hollow profile section abuts the thickened corner region of the corner connector. In this way, dimensionally accurate spacer frame can be manufactured. Normally, the hollow profile sections (incomplete) filled with a called molecular sieve, hygroscopic granules to absorb moisture in the space between the panes and to prevent fogging of the discs can. In order to prevent said molecular sieve from emerging in the region of the corner connector from the hollow profile and enters the space between the panes, it is known to seal the joint between the hollow profile end faces and the corner region of the corner connector with a pasty sealing compound, in particular butyl. For this purpose, the transitions between the connector legs and the corner of the corner connector are covered with said pasty sealant before mounting. When inserting the connector legs in the hollow profile sections, the pasty mass is squeezed in the joint area and seals the critical points.

Corner connectors of the type in question are typically stored and transported as bulk material. However, if they are, as described, covered in the transition regions between connector legs and corner with said pasty sealant, this easily leads to contamination of the entire corner connector and during assembly possibly also to contamination of the hollow profile sections at undesirable locations. It is therefore known to over-coat the region of the corner connectors occupied by sealing compound with a film adhering to the sealing compound. This film must then be removed immediately prior to frame assembly. This leads to a considerable disposal problem of contaminated with sealant films and solves the problem of contamination during assembly only insufficient, since the film can be difficult to peel and thereby takes parts of the sealant. In addition, the assembly process is complicated and thereby delayed and more expensive.

task

It is the object of the present invention to provide an advantageous alternative to the aforementioned film cover, which leads in particular to a simple, pollution-proof and environmentally friendly assembly process.

Such units are then the basis of a mounting method according to claim 10, ie a method for mounting a hollow profile frame, comprising the steps:

• Providing an assembly according to the invention made of corner connector and mounting protective cap,
• Providing two hollow profile sections,
• - Non-positive insertion of the connector legs in the profile interior of a respective hollow profile section to the stop of the corner region of the corner connector of the assembly at the end faces of the hollow profile sections.

Preferred embodiments of the invention are the subject of the dependent claims.

The invention provides to use instead of the known film cover mounting protective caps, which can be positively and / or positively placed on corner connectors and thereby form a distance from the optionally applied sealant protective housing. As a result, on the one hand - as in the known film cover - when storing bulk material a sealing compound contact with other corner joints and therefore their contamination avoided. Unlike the known film cover, however, a contamination of the protective element itself is largely avoided with sealant. In addition, a protective cap according to the invention forms a substantially rigid and therefore easy to handle element, which can be easily placed on the corner connector or removed after assembly of these. The mounting protective caps according to the invention are also easy to collect as bulk and then reusable.

A particular advantage of the mounting protective caps according to the invention is that the actual frame mounting, i. the sliding of the hollow profile sections on the connector legs, can be done with attached mounting protection cap. That During the entire assembly process, the contamination-critical area is surrounded by the protective cap housing. This is especially true for the particularly pollution-critical moment of Dichtmassenquetschung when attacking the hollow profile end faces on thickening corner region of the corner connector.

The protective caps according to the invention may also initially remain on the ready-assembled spacer frame in order to avoid soiling even when it is being stored and transported. In particular, it is possible to remove the assembly protective caps according to the invention until immediately prior to the use of the spacer frame to construct an insulating glass composite.

Thus, the installation method for spacer frame is significantly simplified by the mounting caps according to the invention, the risk of contamination during the entire storage, transport and assembly process is dramatically reduced and due to the reusability of the invention mounting caps the existing in the known film cover disposal problem is solved.

The operating principle of the assembly protection cap according to the invention is that an adapted to the dimensions of the corner connector, angled channel is provided in a housing. The top of this channel is open, so that the corner connector inserted perpendicular to the channel plane or the mounting protective cap can be pushed perpendicular to the channel plane on the corner connector. The bottom of the channel, however, is partially closed. The corresponding bottom wall, which constitutes a stop for the insertion of the corner connector, is elastically flexible. This results in an elastic pivotability of the channel side walls to each other, which can be used to generate a force and / or positive connection between the channel and the corner connector inserted into it.

The free ends of the channel are open, so that the connector legs of the inserted into the channel corner connector protrude from the housing of the mounting end cap according to the invention. This makes it possible to insert the protruding ends in the assembly of the spacer frame in the usual manner in the hollow profile sections. In this case, the hollow profile sections - possibly with elastic expansion of the corresponding channel leg - pushed up to the stop in the channel. Has before mounting this mounting cap according to the invention only embraced the insulated corner connector, it surrounds after mounting both the corner connector and the plugged him on end portions of the hollow profile sections.

The preferred embodiment of the invention is characterized by at least one grid elevation, which extends from the upper edge of a channel side wall parallel to the channel plane. This is therefore a local reduction of the channel width in the region of its upper edge. When inserting the corner connector in the channel, this constriction leads to a through the elastic bottom wall made possible, slight, widening Pivoting of the channel side walls to each other. Once the corner connector is inserted in its entire height in the channel and said grid elevation has happened, the mutually pivoted channel side walls elastically back to their original position, said grid elevation forms a stop against falling out of the corner connector from the channel. With appropriate effort, however, a removal of the mounting protective cap against this locking connection readily possible. In this way, the corner connector can be fixed purely positive and reversible in the channel.

In a preferred embodiment of this embodiment it is provided that a plurality of such locking connections spaced from each other are arranged on both sides of the bending region of the channel. In other words, each channel leg is assigned one or more such grid elevations. As a result, tilting of the mounting protection cap on the corner connector is avoided.

Each grid elevation preferably has run-on slopes acting on both sides perpendicular to the channel plane. Such chamfers reduce the force required for both the postponement of the mounting end cap on the corner connector as well as for the removal after installation.

In order to alternatively or in addition to the described positive connection to create a frictional connection between the mounting end cap and the corner connector or the deferred hollow profile, can be provided in a development of the invention that the channel legs each having a distance from the kinked area constriction. As explained above, the channel side walls should be spaced apart from the connector legs and in particular the sealing compound placed here in the bending region. However, at some distance from the corner, the connector legs are typically not covered with sealant. Here, the channel width can readily be narrowed so far that they contact the connector legs and / or after mounting the outer wall of the hollow profile sections directly, so as to effect a (possibly) non-positive fixation in the channel. In a particularly preferred embodiment of the invention, in which a positive and non-positive fixation is realized, the grid surveys described above are located approximately in the region of the narrowing areas last described.

As mentioned, the channel legs are open at their ends. Preferably, they are widened like a funnel at their open ends. These widenings serve as run-on slopes for the end faces of the hollow profile sections and therefore facilitate their sliding onto the connector legs when the installation end cap is attached.

With regard to the shape of the housing, which is penetrated by the channel, the expert has a wide range of possible variations available. In terms of weight and material minimization, it has proved to be particularly advantageous if the housing consists of two substantially mutually parallel, each pointed roof-like shaped, the channel side walls forming housing walls which are elastically pivotally connected to each other via the bottom wall. As a result, the housing is practically reduced to a few, thin walls, which form the channel side walls and the bottom wall.

Further features and advantages of the invention will become apparent from the following specific description and the drawings.

Description of preferred embodiments

Like reference numerals in the figures indicate like or analogous elements.

The 1 to 4 , which will be discussed below essentially together, show a particularly preferred embodiment of a mounting protective cap according to the invention 10 in different stages of a mounting method according to the invention for hollow profile frame.

The mounting protection cap 10 consists essentially of three housing walls. These are a channel outer wall 12 , a canal inner wall 14 as well as a bottom wall 16 , The canal exterior wall 12 and the canal inner wall 14 are also addressed together as channel side walls. The channel side walls 12 . 14 as well as the bottom wall 16 together form an angled channel 18 in the illustrated embodiment two channel legs arranged at right angles to each other 181 . 182 is composed. The channel legs 181 . 182 are in the kink area 183 of the channel consistently connected. The above designations duct outer wall 12 and channel inner wall 14 refer to the external or internal angle of the bending area with regard to the position information "outside" and "inside" 183 ,

In the illustrated embodiment, the bottom wall 16 on a gimble-shaped surface in the kink area 183 limited. Also conceivable are embodiments in which the bottom wall 16 extends over a larger area of the channel bottom. Likewise, embodiments are conceivable in which the bottom wall 16 is reduced to one or more, the channel underside spanning webs.

The channel top is completely open in any case. This allows insertion of a corner connector 30 from above, ie perpendicular to the paper plane in 1 , in the channel 18 the mounting protection cap 10 , An assembly from a mounting protection cap 10 and an inserted corner connector 30 is in 3 shown.

The corner connector 30 includes two connector legs 301 . 302 , which are arranged at right angles to each other and over a corner area 303 connected to each other. The corner area 303 is compared to the connector legs 301 . 302 thickened to a stop for the aufzuschiebenden hollow profile sections 40 to form, as in 4 shown. The transition areas between the connector legs 301 . 302 to the corner area 303 are with a pasty sealant 50 , especially butyl.

At the upper edge of the channel inner wall 14 are in the range of each channel leg 181 . 182 spaced from the kink area 183 Rest surveys 20 arranged. These serve for the positive fixing of the corner connector 30 in the canal 18 in the manner of a locking connection.

To additionally realize a frictional fixation, which is effective at least in the final assembly state, has the channel outer wall 12 in the area of each channel leg 181 . 182 spaced from the kink area 183 one constriction area each 22 on. In the illustrated embodiment are the constriction areas 22 not in direct, elastic contact with the inserted corner connector 30 , This is therefore purely positive fit in the channel 18 fixed. After postponing the hollow profile sections 40 (see. 4 ) are the constriction areas 22 but in immediate, elastic contact whose outer surfaces. The unit made of corner connectors 30 and hollow profile sections 40 is therefore additionally frictionally in the channel 18 fixed. In other embodiments, a non-positive fixation of the bare corner connector would already be 30 in the canal 18 possible.

The open ends of the channel legs 181 . 182 are widened like a funnel in the embodiment shown. This allows easy sliding of hollow profile sections 40 on the connector legs 301 . 302 one in the channel 18 a mounting cap according to the invention 10 inserted corner connector 30 , When pushing the hollow profile section 40 this is in the respective channel leg 181 . 182 inserted and expands this elastic, especially at passage of the constriction area 22 ,

In the illustrated embodiment, the width of the channel 18 in the kink area 183 chosen so large that an immediate contact between the corner area 303 of the corner connector 30 and the channel side walls 12 . 14 is avoided. In this way, contamination of the channel side walls can be avoided with the sealant.

Of course, the embodiments discussed in the specific description and shown in the figures represent only illustrative embodiments of the present invention. A broad range of possible variations will be apparent to those skilled in the art in light of the disclosure herein. Especially with regard to the special design of the channel 18 Surrounding housing, the expert has largely free choice. The embodiment shown in the figures has proven itself in terms of weight and material minimization. If, on the other hand, a stronger mechanical protective effect is to be achieved and / or the assembly protective caps according to the invention 10 an additional function, such as feet for pre-assembled profile frame meet, can also find voluminous forms use. The mounting protective caps according to the invention are preferred 12 made of plastic, especially in plastic injection molding. It is also conceivable, however, a different choice of material, for example made of metal.
