AT392326B - HOLLOW PROFILE FOR WINDOW AND / OR DOOR FRAME OD. DGL. WITH DRAINAGE OPENINGS - Google Patents

Description

AT 392 326 B

The finding relates to a hollow profile for window and / or door frames or the like and the upper side above and the side flanks lie laterally of the drainage opening to be covered and latching arms extend from the inside of the front transverse part of the cover, which protrude through openings provided on the hollow profile, in particular through the drainage openings, and engage behind these in a force-fitting and / or form-fitting manner.

Hollow profiles with drainage openings covered by covers of this type are known (AT-PS 373 357). Although these have proven their worth, their disadvantage is that covers with different length locking arms are necessary for hollow profiles of different wall thicknesses. This makes the manufacture of such covers more expensive, complicates their storage and requires increased attention during assembly.

In order to counter this disadvantage, it has already been proposed (DGM 81 20 338) to equip the locking arms at the fastening end with a resilient tongue which extends at an acute angle and has a row of locking teeth at its free end. A disadvantage of this embodiment, however, is that, depending on the wall thickness of the hollow profiles, there is a different angular width for the tongue and the secure and firm hold of the cover can thereby be impaired.

The invention is therefore based on the object of designing the cover so that the cover is always kept stable and secure regardless of the wall thickness of the hollow profiles. This object is achieved in that at least the side flanks of the cover are resilient.

Due to the elastic spreading possibility of the side flanks, a rear hooking is always achieved with the same hooking dimension. Preferably, the side flanks of the cover are tapered towards their end. In order to prevent water from penetrating into the drainage openings under the influence of the wind, the cover according to a preferred embodiment of the invention has an elastic, horizontally extending tongue, the end of which lies below the drainage opening on the frame profile The tongue preferably extends at least between the locking arms. The cover on the frame profile is fastened in an advantageous manner in that the latching arms engage behind in the drainage opening. According to an alternative embodiment, the ratchet can also engage in holes that are separate from the drainage openings.

The invention is explained in more detail using an exemplary embodiment.

Fig. 1 is a vertical section through a frame profile with a cover for drainage openings

Fixed glazing;

2 shows a vertical section through a cover on an enlarged scale;

Fig. 3 is a view of the cover from below with two different wall thicknesses of the hollow profiles, partially torn, and

Fig. 4 is a front view of the cover, also with two different profile wall thicknesses.

The guide metal frame profile (1) has a series of drainage openings (2) of length (L) (see FIG. 3) designed as slots for the condensation water forming in the rebate base. The drainage openings (2) are each covered by hood-shaped covers (3) which are designed as small plastic pieces. Each cover (3) has an upper side (4), a front transverse part and an elastically resilient side flank (5). The covers (3) are open to the frame profile (1) and downwards, so that the water can drain downwards. The covers (3) are each attached to the frame profile (1) with locking arms (6). 1) set. In the present exemplary embodiment, the latching arms (6) engage in the drainage opening (2), the profile wall (7) being hooked behind by the latching projections (6 ') of the latching arms (6). However, the locking arms (6) can also engage in bores which are separate from the drainage opening (2).

In Fig. 3 it is shown that regardless of the thickness of the profile wall (7) (the strengths (Dj) and (D2) are shown), the same interlocking dimension (H) results. The interlocking dimension (H) is the dimension with which the latching projection (6 ') of the latching arm (6) engages behind the profile wall (7). At the same time, the position of the resilient side flanks (5) is the thickness (Dj) and (D2) Profile wall (7) shown For the thickness (D2), the position of the side flanks (5) is shown in dashed lines. In this case, the side flanks (5) are spread outward

Li Fig. 3 is also clearly visible that the side flanks (5) are tapered towards their end.

In order to reduce the influence of the wind on the drainage opening (2), the cover (3) has an elastically designed, horizontally extending tongue (8), the end (8 ') of which lies against the frame profile (1) below the drainage opening (2) According to FIGS. 3 and 4, the tongue (8) extends between the two ratchets (6). This tongue (8) automatically adapts to the thickness of the profile wall (7). 4 finally shows a front view of the cover (3), the position of the side flanks (5) with a greater thickness (D2) of the profile wall (7) again being shown in dashed lines -2-
