Description

The subject of the present furnace is a profile strip with corner connection, which is characterized in that the profile strips have grooves through at least an elbow seated in these grooves are connected.

In building construction, especially in the manufacture of doors and windows, metal profiles are often used, whereby so far their connection mainly through verso: sen, by screwing or riveting «, When using profiles made of aluminum, these are for reasons of corrosion protection and also for visual reasons anodized «

A subsequent processing of the profiles is, however, after Hardly or not at all possible without anodizing Damage the anodized layer. The consequence of this is

the disadvantage that the size of the metal profiles depends on the size of the anodized baths available. the Anodized parts also have to be "very carefully packaged for transport because of damage to the anodized layer makes the whole part unusable.

Processes and possibilities are known in the state of the art to connect anodized profiles together. Mostly screws or rivets are used for this. Another kind and way to connect metal profiles with each other consists in the use of so-called corner angles, which are at their ends Have round extensions, and are pressed into corresponding holes in the profiles.

In contrast, according to the present firing system, it is proposed to connect miter-cut profiles that preferably made of metal or plastic, simple elbows to be used in "the grooves of the various Profiles are pressed in. These elbows can easily be made from appropriate material and are on their formed toothed vertical outer sides, this toothing, in addition to which possibly also thickened areas can be, dig into the groove walls. These teeth can be on one or both sides of the Be arranged elbows. The number of teeth can be different, likewise the tooth size and the plank angle of the teeth.

According to a preferred embodiment, the teeth can be a have a slight inclination so that when the angle pieces are punched into the grooves, tensile stress is exerted on the connecting rod arises. .

According to a further preferred embodiment, the elbows are Slightly conical in shape when viewed from top to bottom.

To ensure that the teeth of the contra-angle handpieces are properly buried in The angle pieces should be made to ensure that the walls of the projections consist of a slightly harder material than the profile parts to be connected.

A major technical advantage of the profile strip according to the innovation with a corner connecting device is still that no more drilling work in the profile is necessary, and as a result, time is saved.

Disadvantageously, the connection holes were previously also used for drilling very precise devices or machines are always required, which are usually not used for assembly on the construction site were available.

According to the present innovation, the aluminum profiles can now be anodized in a strand with a normal hacksaw Miter cut and then, without the need for a device, simply by inserting the angle pieces associate.

The innovation according to the profile strip with corner connection device can be used to build two- as well as three-dimensional ■ nal bodies are used, for example in construction from windows and yours, as well as from aquariums, aviaries, showcases and containers is important. Another advantage of the new-provision Profile strip with corner connection device is that differences in the profile grooves or in the Elbows are evened out by the teeth.

With the previously known connection types of profile lists disadvantageously, the accuracy and stability of the 'connection was dependent, among other things, on the dimensional accuracy of the profile grooves and the connection angle itself.

In contrast, it is with the profile strip according to the innovation Corner connection device also possible, in normal angle profiles, the example

wisely are available in stores after cutting to length and making the miter cut, mill hats and the serrated Simply insert the contra-angle handpieces with an appropriate tool.

It can therefore, according to the present innovation, also with the Installation Make dimensional changes that were not possible with the previously known connections, especially not when once holes were made.

With a slight bevel on the elbows, the Facilitate assembly because the angle pieces are then automatically centered in the grooves.

The essence of the present innovation will now be further explained with reference to the accompanying FIGS.

Figure 1 shows a plan view of "the innovation according to the profile.

Profile strip rotated by 90 ° with corner connection device; Figure 3 shows a plan view of the toothed elbow; Figure 4 shows a side view of the toothed elbow and FIG. 5 shows a section on the line III-1II in FIG. 3.

With 1 and 2 the two are mitred and accordingly denotes associated profile strip ends, which have the grooves 1a and 1b and 2a and 2b; in these The toothed angle pieces 3 and 4 are now inserted in the grooves, preferably struck.
