Description
- The present invention regards a corner element for double glazing systems and the like.
- More in detail, the present invention regards a corner element with high air-tightness for mutually connecting the spacer elements of double glazing systems and the like.
- In the industry for the production of double glazing systems and the like, a particularly felt problem regards the perfect sealing of the airtight chamber of the insulating glasses.
- Actually, as known in order to reduce the transmittance value of the insulating glass, the air present in the chamber is replaced, in the production step, with noble gases such as argon and krypton, which have a lower heat transfer coefficient.
- Clearly, in order to guarantee a good efficiency of the insulating glass product, the internal chamber must be perfectly sealed, for preventing the gas from leaking outside.
- Usually a glass insulating system comprises a frame consisting of spacer elements, which are mounted on the sides of the chamber defined between two glass panels, actually for keeping the latter spaced from each other and for preventing the leakage of the gases along the edges.
- The spacer elements, should they not be obtained with a single bent profile, are then connected to each other with suitable corner elements.
- The spacer elements normally have, along the inner surface thereof, micro-holes which allow the dehydration of the inner chamber through special salts contained within the spacer elements.
- Through such micro-holes the noble gases contained within the chamber could leak, thus the corner elements should guarantee the air-tightness of the double glazing system at the vertices, i.e. the joint areas of the spacer elements.
- Currently, manual filling operations with portions of butyl at the joint edges between the corner elements and the spacer elements are carried out in order to obtain the best sealing possible at the corner elements.
- The quality of such manual filling operations, and especially the uniformity and the repeatability of the quality level of the products, mainly depend on the ability of the operator and other several factors: hence optimal quality levels in terms of gas sealing within the chamber are often not obtained.
- For example consider the cases, quite frequent, wherein given certain climatic factors such as heat excursions and the like create an overpressure within the airtight chamber.
- When the work of filling the joints using butyl is carried out in an imprecise manner or however not optimal from a quality point of view, the overpressure within the chamber may determine the lifting or breaking the layers made of butyl, thus seriously jeopardising the sealing of the system.
- The technical task of the present invention is to improve the state of the art, by providing a corner element for double glazing systems and the like in which the permeability to the gases is reduced drastically, hence creating an optimal air-tightness of the glass.
- Within such technical task, an object of the present invention is to provide a corner element for double glazing systems and the like capable of allowing reducing the assembling times also eliminating all the typically very laborious, and poorly repeatable manual operations of closing the angles using butyl or other similar sealing materials.
- This task and these objects are attained by the corner element for double glazing systems and the like according to the attached
claim 1. - The corner element according to the invention comprises a first and a second arm adapted to be inserted in respective spacer elements and, at each of such arms, a respective abutment surface for the end edge of the respective spacer element.
- In proximity of the abutment surface there is provided a seat for a layer of sealing material - such as butyl or the like - adapted to guarantee the optimal sealing in the joint area between each arm and the respective spacer element.
