Definitions

  • the present invention relates to a spacer for insulating glazing and to an insulating glazing comprising a spacer frame formed by assembling several spacers.
  • the invention also relates to a method of manufacturing a spacer for insulating glazing.
  • insulating glazing can be obtained by joining a rigid spacer frame to the periphery of two sheets of glass using sealing cords and by applying an external sealing barrier around the entire outer circumference of the spacer frame between the two glass sheets, so as to maintain the glass sheets between them and on the spacer frame.
  • the spacer frame comprises a desiccant material in its interior volume, in order to ensure dehydration of the or each cavity formed between the sheets of glass of the insulating glazing.
  • the spacer frame is conventionally manufactured either by successive bending of a straight section of ductile material such as aluminum, or by angular assembly at their ends of four straight sections, so as to obtain a rectangular frame.
  • the filling of the spacer frame with the desiccant material is generally carried out just before the closing of the frame, in particular at the level of a last open corner of the frame, in order to prevent any leakage of the desiccant material.
  • the assembly of the spacer frame is not carried out directly on the insulating glazing manufacturing line, but on an independent island. Filling with desiccant material when it takes place at the time of closing the spacer frame cannot therefore be integrated in line.
  • filling with desiccant material when the spacer frame is closed is not suitable when the spacer frame is assembled around at least one central sheet of glass, as is the case for glazing multiple with spacers as described in US 2012/0141699 A1 . Indeed, there is then a risk of damage to the central sheet of glass by the filling device with desiccant material.
  • the filling of the cavity of an insulating glazing with gas is conventionally done through a through orifice formed in the spacer frame.
  • the installation of such a through hole in the spacer frame generates a risk of leakage of desiccant material and pollution of the insulating glazing with the desiccant material when filling the cavity of the insulating glazing with gas through the orifice crossing.
  • US 4,407,105A discloses another spacer frame for insulating glass.
  • the invention more particularly intends to remedy by proposing a spacer for insulating glazing, the manufacture of which, including the filling with desiccant material, can be carried out in line, this spacer being compatible with an assembly of the spacer frame around at least one central sheet of glass and making it possible to simplify the method of filling the cavity of an insulating glazing unit with gas comprising the spacer, without the risk of leakage of desiccant material or of pollution of the insulating glazing unit with the desiccant material .
  • the subject of the invention is a spacer for insulating glazing, comprising a profile which comprises at least one tubular part defining a housing for receiving desiccant material, where the housing opens out at two ends of the tubular part, the housing being closed near each end of the tubular part by means of a plug and comprising a desiccant material between the two plugs, at least one of the plugs being offset longitudinally inside the housing with respect to the corresponding end of the tubular part, where the tubular part comprises a through hole, intended for the passage of gas between a cavity of the insulating glazing and the exterior of the insulating glazing for filling and/or evacuating gas from the cavity, which is provided in a section of the tubular part between an offset plug and the corresponding end of the tubular part, where the through orifice opens into two walls of the part tubular intended to extend transversely relative to the glass sheets of the insulating glazing, with a wall intended to be directed towards the cavity of the insulating glazing and a wall intended to

  • the invention is concerned with straight rigid spacers, intended to be assembled angularly at their ends with other similar spacers to form an insulating glazing spacer frame, as opposed in particular to flexible spacer cords which can be extruded directly onto a glass sheet of insulating glazing with a change in direction of the extrusion head in the corners.
  • the invention takes advantage of the fact that the section between an offset stopper and the corresponding end of the tubular part is empty, without desiccant material in its interior volume, in order to provide there a through orifice for filling and/or evacuation of gas from a cavity of the insulating glazing.
  • the arrangement of the through hole in a section between an offset plug and the corresponding end of the tubular part makes it possible, when drilling the profile of the spacer, to avoid any risk of leakage of the desiccant material through the through hole.
  • this arrangement allows the cavity of the insulating glazing to be filled with gas through the through-hole without the risk of pollution of the insulating glazing with the desiccant material, since the desiccant material is confined to the rear of the cap delimiting the section. This results in a simplification of the process for filling the cavity of the insulating glazing with gas comprising a spacer according to the invention, and therefore a reduction in manufacturing costs.
  • each cavity of the insulating glass between the sheets of glass can be filled with air.
  • each cavity of the insulating glazing comprises a layer of insulating gas, which replaces the air between the sheets of glass.
  • gases used to form the layer of insulating gas in each cavity of the insulating glazing include, in particular, argon (Ar), krypton (Kr), xenon (Xe).
  • the layer of insulating gas in each cavity of the insulating glazing comprises at least 85% of a gas having a lower thermal conductivity than that of air. Suitable gases are preferably colorless, non-toxic, non-corrosive, non-flammable, insensitive to exposure to ultraviolet radiation.
  • the steps for manufacturing the spacer can be carried out in line, on an insulating glazing production line.
  • a spacer according to the invention which is filled with desiccant material prior to its assembly with other similar spacers, can be easily manipulated by an operator or a robot to form a spacer frame, without risk of the material leaking. desiccant since it is confined between two plugs inside each tubular part.
  • the fact that the spacer is pre-filled with desiccant material also allows its use for assembling a spacer frame around at least one central sheet of glass, as may be required for the manufacture of multiple glazings having at least at least three sheets of glass, avoiding the need to fill the frame with desiccant material after its assembly around the central sheet of glass.
  • the spacer pre-filled with desiccant material according to the invention can advantageously be manufactured just before its implementation in insulating glazing, which limits the prior absorption of humidity by the desiccant material and improves the quality of the insulating glazing.

  • the housing for receiving desiccant material is delimited by the side and transverse walls.
  • the transverse wall which is directed towards the cavity of the insulating glazing is provided with a plurality of perforations on its part between the two closing plugs of the housing, so as to put in communicating the desiccant material with the air or gas inside the cavity.
  • the desiccant material can thus absorb the humidity contained in the cavity and prevent the formation of mist between the glass sheets of the insulating glazing.
  • the through hole is provided with a shutter allowing the injection of gas into the cavity of the insulating glazing from the outside, using a gas injection element which passes through the shutter from the outside, such as a nozzle or a syringe, the obturator being moreover designed to prevent the exit of the gas from the cavity once the cavity is filled.

  • the member among the valve or the seat which is deformed when the gas injection element is introduced into the shutter can in particular be made of a shape memory material. Examples of shape-memory materials include in particular shape-memory alloys such as nickel-titanium alloys, or shape-memory polymers such as polyurethanes.
  • such a shutter forming a gas filling valve can comprise at least one part based on a self-healing material, which allows the passage of the gas injection element through the shutter for the gas filling of the cavity of the insulating glazing from the outside, and which heals when the gas injection element is removed, which prevents the exit of the gas from the cavity of the insulating glazing once the cavity is filled.
  • self-healing material is meant a material capable of self-repairing after having been damaged by perforation, in particular by regaining all of its gas-tightness properties.
  • a self-healing material regains its original configuration identically before drilling, through a physico-chemical process guaranteeing tightness even under high pressure differences.

  • the self-healing material can in particular be chosen from multifunctional fatty acids, monomers or acrylic polymers, polyurethanes and copolymers based on polyethers, preferably di-block polymers based on polyethers for which the mobility of the polymer chains allows rapid self-healing even at low temperatures.
  • the shutter of each through hole of the spacer is chosen with a color of its visible parts on the surface of the spacer which is substantially identical to the color of the profile of the spacer, so as to give the spacer the most aesthetic visual aspect possible.
  • the or each section of the tubular part between an offset stopper and the corresponding end of the tubular part has a length of the order of 2 cm to 5 cm.
  • a length of the order of 2 cm to 5 cm is available.
