Definitions

• the invention relates to a connector for
• Such a connector is known from EP-0 283 689 AI. It has one or more retaining elements on its bottom or middle bar and on the side walls, which are clawed into the wall of the pushed-on hollow profiles and secure the connector against unintentional removal.
• the connector comes with its
• the frame inserted into the hollow profiles.
• the latter generally have one or more rows of perforations on their wall on the inside of the frame, which allow the air in the window interior to access the drying agent contained in the spacer frame.
• the previously known plug connector lies on these perforations with its central web or engages with the retaining elements between the perforations.
• the retaining elements are supported on the smooth inner walls of the profile.
• the invention solves this problem with the features in the main claim.
• one or more spring tabs are arranged in the area of the perforations, which engage the perforations or rows of holes.
• Perforations are usually punched or pressed from the outside into the hollow profile wall and form on the inside of the wall raised press beads or the like other supernatants.
• the spring lugs can catch on these positively and thus offer greater retention and pull-out resistance than when attacking a smooth inner wall of the profile. Spring lugs offer particularly good support, which cannot be achieved in the same way with rigid retaining elements.
• the spring lugs are preferably cut out of the wall of the connector or punched out and bent out. As a result, there are wall openings in their area, which also allow access to the interior of the pane to the drying agent in the connector area. For this it is further advantageous if the connector has open end faces and absorbs drying agent in its interior.
• the spring lugs are preferably arranged in a recess. This increases the spring length and gives the spring lugs more elasticity. It is sufficient if the feather lugs extend with their edges approximately to the level of the recess edges.
• the spring noses are accordingly arranged side by side when arranging several parallel rows of perforations. They are at about the same height and are deliberately offset axially from each other. This has advantages with regard to the frequently occurring axial misalignment of adjacent rows of perforations.
• the spring nose offset ensures that at least one or some spring nose (s) meet and engage behind the perforation bosses.
• the spring noses should reach into the valleys between the perforation bosses as far as possible.
• the connector preferably has a cover plate which is raised in relation to the depressions and which lies against the inner wall of the hollow profiles and sealingly engages and covers the connection or joint of the hollow profiles.
• FIG. 1 a connector with spring tabs for the profile perforation in plan view
• FIG. 2 shows a section through the connector according to section line II-II from FIG. 1,
• Figure 3 a variant of the connector of
• Figure 4 a cross section through the connector according to section line IV-IV of Figure 3 in the installation situation in a hollow profile.
• Figures 1 to 4 show a connector (1) for hollow profiles (2). This is preferably a straight connector.
• the connector (1) can also be a corner bracket.
• the hollow profiles (2) are pushed onto the connector (1) on both sides.
• the hollow profiles (2) preferably form one
• Spacer frame for an insulating glass pane can consist of any suitable material, for example a light metal alloy.
• the thin profile walls tend to deform and dodge when the retaining elements of the connector (1) are clawed into place. With such profiles, the holding forces can therefore only be transmitted and absorbed to a limited extent.
• the hollow profiles (2) have one or more row or line perforations (3, 4) running in the axial direction on their wall facing the inside of the frame (15) or the inside of the pane.
• the connector (1) has one or more elastic spring lugs (9, 10) in the area of the perforation (s) (3, 4).
• the spring lugs (9, 10) are narrow and preferably have a width which essentially corresponds to that of the perforation (3, 4).
• the spring lugs (9, 10) are arranged on the bottom (5) of the plug connector (1) which faces the inside of the frame (15). They are arranged on both sides of the center line (17) of the plug connector (1) and are directed opposite to this center line (17).
• the spring lugs (9, 10) claw at the perforations (3, 4) when the hollow profiles (2) are attached and, if possible, lie behind the humps or craters or reach into the spaces between them. As a result, the spring lugs (9, 10) spread elastically against the hollow profiles (2) and offer good support that prevents the hollow profiles (2) from being unintentionally removed from the plug connector (1).
• the spring lugs (9, 10) have particular advantages for the preferred thin-walled and relatively unstable hollow profiles (2).
• the wall deformations formed by the humps or craters offer increased stability of the hollow profile wall and improved resistance to deformation.
• the spring noses (9,10) holding forces are absorbed and removed without wall deformation.
• Figures 1 and 3 show different embodiments for the number and arrangement of the spring lugs (9,10).
• the spring lugs (9,10) are arranged side by side in pairs. They are at approximately the same height and are axially offset from each other by a small amount. If several spring lugs (9, 10) are arranged one behind the other on each connector half, these have the same distance from one another in the axial direction, so that there is approximately the same axial offset in all spring lug pairs. In the longitudinal direction, however, the distances between the spring lugs (9) and (10) can also vary.
• the axial offset of the spring lugs (9, 10) lying next to one another is preferably a few tenths of a millimeter in size.
• the axial offset of the spring lugs (9, 10) takes into account the axial displacements of the perforations in the perforation rows (3, 4) that are common in practice.
• the spring nose offset can e.g. make up about a quarter or half of the hole spacing of the perforations (3, 4).
• each recess (11) has two pairs of spring lugs (9, 10).
• the bottom (5) in the central region (17) has a raised cover plate (12) which, in the installed position, lies tightly against the hollow profile wall facing the inside of the frame (15) and the one located there Connection point of the hollow profiles (2) covers and seals. At the outer edges of the connector (1) further raised areas can connect to the recesses (11).
• the spring lugs (9, 10) have a length which is approximately matched to the height of the depressions (11). They extend approximately to the level of the upper recess edges or at the level of the cover plate (12).
• the spring lugs (9, 10) are cut out of the base (5) and bent out. This creates openings in the floor.
• the free cuts are tight and the openings are relatively small.
• the free cuts (14) are larger.
• the resulting nostrils in the base (5) are larger.
• this allows the spring lugs (9, 10) to deform more easily under the influence of the perforation bosses.
• the larger openings in the inner pane air give more access to the granulated drying agent, which is preferably collected in the connector (1).
• the bottom (5) can have one or more channels (13) in the raised areas (12) along the perforations (3, 4). As shown in FIG. 4, these channels (13) take up the perforation bosses and cover them.
• the channels (13) can also have small openings for air access, at least in the outer regions. In Figure 4, the installation position is for the better
• the connector (1) has one or more center stops (7) in the center area (17).
• the center stops (7) are arranged on the side walls (6) of the U-shaped or box-shaped connector (1) in cross-section and are designed as oppositely directed and laterally flared spring tabs.
• the connector (1) has several retention elements (8) of any design, e.g. issued retention lugs on the side walls (6). Apart from the spring lugs (9, 10), the connector (1) can otherwise have the same design as the connector from EP 0 283 689 AI.
• the connector (1) is preferably open at the end faces, so that the granulated drying agent located in the spacer frame or in the hollow profiles (2) can flow over the joint of the hollow profiles (2) and the connector (1).
• the connector (1) can consist of any suitable material or of composite materials. In the preferred embodiment, it is a stamped and bent part made of a metal sheet, e.g. Sheet steel. The shape is achieved by punching and bending. In the embodiment shown, the plug connector (1) is U-shaped in cross section, the central web forming the bottom (5) and pointing to the inside of the frame (15). The connector (1) is open to the outside of the frame (16).
• the arrangement of the spring lugs (9, 10) vary.
• the axial offset can be greater or, alternatively, also fall away.
• the connector (1) has the same number of rows of spring tabs as there are perforations. This assignment can also be different. Otherwise, any configurations and modifications of the other parts of the connector are possible.
