Definitions

  • the invention relates to a spacer and a connector for insulating glass with the features in the preamble of the main claim.
  • a straight connector for spacers of insulating glass is known, which is formed as a stamped and bent part of sheet steel with a U-shaped cross-section.
  • the side bars have at the lower edge in the region of the junction on triangular wide stops for the hollow sections.
  • the stops have flanks on both sides with a large flank angle of significantly more than 90 °.
  • the flanks serve as run-on slopes to which the plugged hollow sections should start without digging. Due to the wedging action of the run-up slopes, the plugged-in-height plug connector in the hollow profiles is pressed up against the restoring force of spring tongues. The spring tension presses the attacks back into the joint, whereby the hollow sections can be driven apart.
  • the hollow profiles have prepared lateral grooves for receiving the stops. This arrangement requires a processing of the hollow sections, which is costly and time consuming and incompatible with an automated production of spacers.
  • the invention solves this problem with the features of the two independent claims.
  • the invention has the advantage that a completely tight connection of the profile end walls can be achieved by the complete digging of the small stops on the profile end walls without otherwise negative effects must be taken into account.
  • a height-free guide of the connector in the hollow sections which preferably fixes the connector side walls, has the advantage that the attacks can be very small and yet come safely in contact with the profile end walls. They can not be pushed over when attaching the hollow profiles.
  • the attacks must not compensate for the height tolerances of the connector in the hollow sections. Rather, the connector via a separate tolerance compensation on side walls can be performed without clearance. This also prevents the formation of unfavorable restoring forces on the connection point.
  • the connector is securely and firmly guided in the hollow sections.
  • connection point Due to its solid side walls in the region of the connection point, it is particularly resistant to bending and deformation at this heavily loaded point.
  • the tolerance compensation can also improve the inherent stability of the connector. Notch effects in this area are largely avoided.
  • the high structural strength and flexural strength allow the wall thickness of the connector to be reduced and cost savings.
  • the stops the more important is the dimensional accuracy of the connector.
  • the connector in a metallic embodiment, it is advantageous to produce the connector from a pre-refined material that requires no later post-treatment. This ensures that the tiny stops retain their shape and do not break off during a post-treatment or otherwise deformed.
  • the metal in particular a so-called cold rolled steel strip, is preferably made of stainless steel. This can be done by galvanizing and / or chromating before punching and bending the material. A subsequent quenching or other post-treatment of the connector is eliminated. This reduces the tolerance problems and the number of control measures, which ultimately also results in a more cost-effective production.
  • Figures 1 to 4 show a straight connector (1) for use in the spacers (2) shown in Figure 5 and 6 for insulating glass panes.
  • the spacer (2) consists of one or more curved and / or straight hollow profiles (3,4), which are stumped at the junction (5) and held together by the straight connector (1) used there.
  • the connector (1) is preferably made as a stamped and bent part made of metal, in particular made of sheet steel. It has a substantially U-shaped in cross-section and is preferably open at the end faces (21). As a result, the granulated drying agent in the hollow profiles (3, 4) can flow through the inner cavity (22) of the connector (1) via the connection point (5).
  • the connector (1) preferably has in the middle two at the same height lying, rigid and double-acting stops (12).
  • the stops (12) are arranged on the edges (11) of the side walls (10) of the connector (1) and protrude beyond this.
  • the stops (12) are in the wall plane and have the small wall thickness of the side walls (10), which is smaller than 1 mm and in the preferred embodiment is about 0.5 mm.
  • the stops (12) have a substantially triangular shape with oblique edges (13) having between them an acute flank angle ⁇ of less than 90 °, preferably about 45 °. At the tips of the stops (12) may be rounded.
  • flanks (13) may also be formed straight and parallel. They are then at right angles to the connector longitudinal axis (20). In this case, the flank angle ⁇ is 0 °.
  • the rigid stops (12) are very small. They have at the height of the side wall edges (11) has a width (b) of less than 0.5 mm, preferably about 0.3 to 0.15 mm. Its height (h) is also less than 0.5 mm, preferably 0.3 mm or smaller.
  • the edges (11) of the side walls (10) on both sides of the stops (12) free cuts or recesses (14), in which the flanks (13) terminate with a kerb facilitatoren rounding.
  • the stop height (h) can be calculated from the bottom of the free cuts (14).
  • the cutouts (14) jump back approximately 0.15 mm from the side wall edges (11).
  • the stops (12) project with their tips at a stop height (h) of 0.3 mm by 0.15 mm beyond the edges (11). This supernatant can be approximately in the order of the tolerance range of the hollow profile dimensions.
  • the connector (1) has at the connection point (5) the stops (12) opposite a tolerance compensation (16). It serves the exact and height-play-free guidance of the connector (1) in the hollow sections (3,4) at least in the region of the connection point (5).
  • the guide preferably acts on the side walls (10). This ensures that the edges (11) of the side walls (10) against the facing hollow profile inner wall (8) and the tiny stops (12) securely in contact with the end walls (6) of the hollow sections (3,4) and not overshoot can be.
  • the tolerance compensation (16) can be formed in any suitable manner, for example as a cut and bent spring nose (s) on the middle wall (9).
  • the tolerance compensation (16) consist of bump-like two-sided run-on slopes (16) which are formed as a bulge or bulge on the middle wall (9) and / or on the adjacent edges or edge beads (18) of the side walls (10).
  • the curved run-off slopes (16) also cause them to solidify the connector (1) and stabilize by increasing the bending cross-section.
  • the bends also have the advantage that at the junction (5) no cuts on the middle or side walls (10,9) and thus no wall weakening or notch effects are present.
  • the vertex is at the joint (5), the width of the run-up slopes (16) being several millimeters, e.g. about 10 mm, can be.
  • the hollow profiles (3,4) slide on.
  • the rete.g. 0.15 mm The height of the tolerance compensation or the starting bevels (16) is a few tenths of a millimeter, e.g. 0.15 mm.
  • the stops (12) serve to limit the immersion depth of the connector (1) in the hollow sections (3,4) when plugging and for centering in the hollow sections (3,4). As shown in FIGS. 5 and 6, the hollow sections (3, 4) are pushed simultaneously or successively from the end faces (21) onto the plug connector (1) and meet at the connection point (5) in the connector center.
  • the rigid stops (12) dig into the end walls (6) of the hollow sections (3, 4), which is promoted by the minuteness and thinness of the stops (12) and the steep flank shape. Slipping is preferably prevented in favor of burial.
  • the stop height (h) is smaller than the wall thickness of the hollow sections, which also supports digging. The stops (12) dive completely into the end walls (6). This has the consequence that the hollow profiles (3,4) and the end walls (6) at the connection point (5) can close together.
  • the height-play-free and precise guidance of the connector (1) is advantageous in order to prevent run-on and sliding over of the stops (12).
  • the connector (1) can otherwise be designed in any way.
  • the center wall (9) is substantially solid and has no wall openings.
  • it may have planar projections (17) with a substantially cuboidal shape.
  • three uniformly distributed over the length projections (17) are present, of which the middle at the connection point (5) is arranged and can be formed as a run-on slope (16).
  • the connector (1) designed as a stamped and bent part does not have a centering device (23) for exact bending of the U-shape.
  • the centering device (23) can be designed in any suitable manner. In the exemplary embodiment shown, there are two center-punched centering bores (23) on the connector ends, through which search pins grip during bending and guide the board centering and in a form-fitting manner relative to the bending tool.
  • the centering holes (23) are preferably located on projections (17).
  • the retention of the connector (1) in the hollow sections (3,4) can be secured in various ways.
  • In the preferred embodiment are on both sides and at a distance from the connection point (5) retaining elements (15) on the side walls (10). This may be, for example, free-cutting and obliquely downward and externally issued spring lugs.
  • the retaining elements (15) can also be designed completely differently, e.g. It is also possible to make the position assurance by Wandverstemmung in which the hollow profile walls are deformed from the outside into corresponding recesses on the middle wall (9) and / or the side walls (10) , This creates a positive engagement.
  • the connector (1) is adapted in its cross-sectional configuration and its dimensions to the interior of the hollow profiles (3,4). As Figure 6 illustrates, it is preferably installed in a position in which its middle wall (9) rests on the profile bottom (7).
  • the profile bottom (7) is located on the inner wall of the spacer (2) and faces the interior space between the insulating glass panes (not shown).
  • the side walls (10) face the profile roof (8) and may be slightly oblique, to thereby resiliently press against the profile side walls.
  • the connector (1) consists of a pretreated or precoated material.
  • the pretreatment can, for example, serve for corrosion protection, in particular rust protection, and consist of galvanizing and / or chromating.
  • As the base material low-carbon steels, e.g. STK2.
  • the so-pretreated so-called. Cold strip is then punched in the connector production and bent into the required shape.
  • Pretreatment eliminates reworking and post-treatment of the connector (1). This can be dispensed with a subsequent tempering or the like.
  • the connector (1) is ready for use after punching and bending. This benefits above all the small and sensitive attacks (12).
  • the connector (1) may also have a completely or partially closed box shape.
  • the stops (12) can also sit elsewhere. Furthermore, their number may vary.
  • the tolerance compensation (16) can be realized or eliminated in other ways.
