Definitions
- the invention relates to a corner connector for insulating glazing, a glazing with such a corner connector, a method for its preparation and its use.
- Insulating glazings are made of at least two panes, which are connected to each other via at least one circumferential spacer.
- these spacers are designed as hollow body profiles, the side surfaces of which abut the discs, while the inner sides of the spacer point in the direction of the disc space.
- This is referred to as glazing interior space between the panes is filled with air or gas, but in any case free of moisture. Too high a content of moisture in the glazing gap leads to the condensation of water droplets in the space between the panes, especially at cold outside temperatures, which must be avoided at all costs.
- hollow body spacers filled with a desiccant may be used, for example.
- WO 2013/104507 A1 describes a polymeric hollow-body spacer with improved tightness and insulation effect.
- hollow body spacers When mounting a glazing unit hollow body spacers are used in the form of individual profiles, whose length varies according to the length of the manufactured glazing. These are assembled in the subsequent assembly step by means of connectors to form a hollow profile frame.
- Connectors can be used in the form of straight connectors on the glazing edges as well as corner connectors. At such connectors are diverse requirements in terms of stability of the connector and in the sense of a rapid production process. On the one hand, it must be ensured that the connectors are easy to apply in the production process, on the other hand, it must be ensured during further handling of the profile frames that the connectors remain under force in the hollow profile and do not slip out.
- DE 19850491 A1 discloses a metal connector for spacers which has locking elements which prevent the connector from slipping out of the spacer profile.
- Recent developments in the field of connectors are rather directed to polymeric connectors that are easy and inexpensive to produce by injection molding.
- EP 2281994 A2, EP 2066861 B1 and DE 202012103899 U1 be mentioned.
- a variety of technical advances in this area mainly concerns the secure locking of the connector in the spacer by various retaining elements and the compensation of manufacturing tolerances of the spacer through the connector.
- DE 38221 17 A1 discloses a corner connector for connecting hollow profile spacers of insulating glazings, which has an improved tightness.
- WO 2012/139908 A1 discloses a corner bracket for hollow profile spacers of insulating glazings, wherein the corner angle has two legs with on the inside of the leg each an inner region with anchoring ribs and an outer region with sealing ribs. The inner area is adjacent to the corner of the corner angle.
- the height of the anchoring ribs within the inner region is constant, while the height of the sealing ribs within the outer region is also constant and the sealing ribs have a greater height than the anchoring ribs.
- a frame made up of a plurality of spacers and connectors is first preassembled, to which a plurality of disks are applied in the further process. If a rectangular shape of the subsequent glazing is desired, which is by far the most common geometry shape, four spacer profiles with four corner connectors are assembled into a frame. In the further process steps must be ensured by a corresponding design of the corner connector that this remains even when transporting the frame in the spacer and does not slip out. Even with a sufficient lock However, the corner connector may cause damage to the spacer by transport. With manual handling of the frame, it is grabbed by a production worker at two opposite edges and placed in the appropriate place in the production line.
- the object of the invention is to provide a corner connector for hollow profile spacers of insulating glazings, which prevents damage to the spacer during transport of a preassembled spacer profile frame, an insulating glazing with such a corner connector, and to provide a method for their preparation.
- the corner connector comprises at least a first leg and a second leg, which are connected via a corner region, wherein the corner connector can be inserted by means of the legs in a hollow profile spacers of insulating glazings.
- the first and the second leg of the corner connector each comprise at least one leg inner side, which after mounting the corner connector in an insulating glazing in the direction of the profile bottom of the spacer and the glazing interior and at least one leg outside, in the mounted state to the profile roof of the spacer and the outer pane space point.

- the outer region can either also have a slope or run parallel to the outer side of the leg.
- the inner region of the corner connector starting from the corner region has a positive slope in the direction of the end face of the associated leg and the support surface thus increases in this inner region of the inner leg side of the corner region in the direction of the outer region and the front side, is one plugged onto the corner connector Hollow profile spacers in the inner region of the corner connector not directly to this.

- Each limb (2.1, 2.2) has in each case a limb outer side (4), in each case a limb inside (3), in each case one end face (5) and in each case two side surfaces (6).
- the leg inner sides (3) have a length of 25 mm measured between the corner region (9) and end face (5) and a width of 8 mm.
- the leg inner sides (3) are divided into an inner region (1 1) adjacent to the corner region and an outer region (12) which extends between the inner region (1 1) and end face (5) is located.
- the inner region (1 1) has a length of 9 mm and the outer region (12) has a length of 16 mm.
- the leg outer sides (4) and the leg inner sides (3) have no retaining elements. Only at the four side surfaces (6) of the corner connector in each case a retaining element (7) is attached in the form of a wire.
- the wire has a diameter of 0.5 mm and protrudes by 1 mm beyond the associated side surface (6). Since wire-shaped retaining elements cause a very good locking of the corner connector in the plugged spacer further retaining elements are not necessary.
- the legs (2.1, 2.2) are formed of a monolithic material and each have a taper (8) adjacent to the corner area.
- the inner bearing surfaces (10) in this embodiment correspond directly to the leg inner sides (3).
- the monolithic shape contributes to the stability and ease of manufacture of the corner connector.
- the taper (8) forms a rising from the corner region (9) in the direction of the end faces ramp.
- the inventive profile of the inner bearing surface (1 1) causes when mounting a profile frame comprising the corner connector according to the invention according to Figure 5 surprisingly no load fracture of the tread occurs.
- FIG. 6 shows a perspective view of a further corner connector according to the second preferred embodiment of the corner connector according to the invention.
- the construction corresponds essentially to that described in FIG. 5, wherein the outer side of the leg (4) also has a taper (8) in the inner region (11).
- the inner side of the leg (3) and the outer side of the leg (4) run symmetrically with respect to one another.
- equivalent protection is provided even in the case of the profiled roof.
- Figure 7 shows a profile frame of four corner connectors according to Figure 5 and four Hohlprofilabstandshaltern in cross section.
- the legs (2.1, 2.2) of the corner connector (1) are inserted at the open edges (15) of the hollow profile spacer (17) in the cavity (21), resulting in a rectangular profile frame (22).
- the corner region (9) of the corner connector (1) now forms the corner region of the profile frame (22), whereas the legs (2.1, 2.2) are completely inserted into the spacer and are no longer visible from the outside.
- the profile roof (20) of the hollow profile spacer (17) forms the outer periphery of the rectangle, while the profile bottom (19) defines the inner periphery of the rectangle.
- the cavity of the hollow profile spacers (17) is filled with desiccant (27).
- FIG. 8 shows a cross-section of an insulating glazing (16) comprising a profile frame (22) according to FIG. 7.
- the hollow profile spacer (17) is bonded by means of a primary sealing means (28) between two glass panes (23).
- the primary sealant (28) is applied to the side walls (18) of the hollow profile spacer (17).
- the discs (23) and the profile bottom (19) of the hollow profile spacer (17) define an inner space between the panes (26) of the insulating glazing (16).
- the discs (23) and the profile roof (20) form an outer disc space (25) which is filled with a secondary sealing means (29).
- the hollow profile spacer (17) comprises a glass fiber reinforced polymeric body containing styrene-acrylonitrile (SAN) and about 35% by weight glass fiber.
- SAN styrene-acrylonitrile
- the spacer has a cavity (21). Within the cavity (21) a desiccant (27), for example molecular sieve, is arranged. This Desiccant (27) may be filled into the cavity (21) of the spacer prior to assembly of the glazing.
- the profile bottom (19) comprises smaller openings (24) or pores, which allow a gas exchange with the inner space between the panes (26).
- the wall thickness of the hollow profile spacer (17) is 1 mm, while the height of the hollow profile spacer (17) is 6.5 mm.
- the width along the profile bottom (19) defines the distance of the discs (23) and is 12 mm.
- the insulating glazing (16) During the assembly process of the insulating glazing (16), damage to the profiled floor (19) in the corner region of the profiled frame is avoided by using the corner connectors according to the invention.
- the resulting insulating glazing (16) thus also has a perfectly intact spacer in the corner region, so that a better sealing of the glazing is achieved.
