Abstract
Description
- The present disclosure relates to an insulated glazing system and an associated assembly method as defined in the preambles of
claims 1 and 10 respectively. - More in detail, the present disclosure concerns an insulated glazing system having a spacer element and/or screens and/or blinds or other similar elements, and the method of assembling the insulated glazing system.
- In the manufacture of insulated glazing systems, the need is strongly felt to reduce the time required to produce an insulated glazing system and to make assembly operations by the personnel less prone to errors.
- More in detail, the time required to set up an insulated glazing system must be minimized, provided that the basic requirements of the insulated glazing system are met, i.e.:
-
- minimizing emissions of gases in the insulated glazing unit to the atmosphere and
- providing a seal against penetration of moisture from the atmosphere into the insulated glazing unit.
- An insulated glazing system usually comprises a frame composed of one or more spacer elements, which are mounted to the sides of the chamber defined by two glass panes, to maintain the latter in spaced relationship and prevent gas leakage along the edges.
- The spacer elements are either connected by appropriate corner elements or formed as a single element folded into a closed frame.
- Spacer elements with low linear heat transfer coefficients, known as “Warm Edge” are already available and have the purpose of supporting the insulated glazing system and also of acting as supports for elements such as screens, blinds or the like, to be installed within the insulated glazing unit.
- For example, EP 2764191 discloses a spacer element that allows fixation of screens, blinds and the like within the insulated glazing unit.
- Nevertheless, while the insulated glazing system of EP 2764191 meets all design requirements for insulated glazing systems, the fixation of screens, blinds and the like within the insulated glazing unit still requires skilled personnel, as well as operations that might damage, in certain cases, the spacer element and/or the support element.
- Furthermore, the special movements that the personnel is required to perform to fix the screens, blinds and the like to the spacer element increase manufacturing times, which will reflect on higher costs for the manufacturer and, as a result, for the final user,
- The object of the present invention is to provide an insulated glazing system and an associated assembly method that allow quicker and more efficient fixation of screens, blinds and the like to the spacer element within the insulated glazing unit, with the same reliability as prior art insulated glazing systems.
- This object is fulfilled according to the invention by an insulated glazing system as defined in claim 1.
- The object is also fulfilled according to the invention by a method of assembling an insulated glazing system as defined in
claim 10. - In one embodiment, an insulated glazing system is provided, which can minimize emissions of the gases in the insulated glazing unit to the atmosphere and provide a seal against penetration of moisture into the insulated glazing unit.
- Also, the present invention provides a method of manufacturing an insulated glazing system that is quicker and more efficient than prior art methods, while ensuring compliance with the other design specifications.
- The characteristics and advantages of the present disclosure will appear from the following detailed description of a possible practical embodiment, illustrated as a non-limiting example in the set of drawings, in which:
-
FIG. 1 shows an axonometric view of the insulated glazing system during an assembly step, including a spacer element and with a glass pane removed; -
FIG. 2 shows an axonometric view of the insulated glazing system of FIG. 1 during another assembly step, including a box and two profiles; -
FIG. 3 shows an axonometric view of the insulated glazing system ofFIG. 2 during a further assembly step, including engagement means; -
FIGS. 4A, 4B and 4C show a cross sectional view of the next assembly steps of the insulated glazing system ofFIG. 3 ; -
FIG. 5 shows an axonometric view of the insulated glazing system ofFIG. 3 during a further assembly step, including the other glass pane; -
FIG. 6 shows an axonometric view of the insulated glazing system ofFIG. 5 during a further assembly step, including control means. - Referring to the accompanying figures, numeral 1 generally designates an insulated glazing system comprising a
first glass pane 2 and a second glass pane 3 (FIGS. 5 and 6 ), and aspacer element 4 to define a so-called insulated glazing unit. - As used herein, the term insulated glazing unit is intended to designate a substantially hermetically sealed volume, which is designed to contain:
-
- devices for driving the movement of the blind, screen or the like, including the mechanical, electrical, electronic elements required for driving the movement of the blind, screen or the like
- air or more preferably noble gases such as argon or krypton, which are characterized by lower heat transfer coefficients as compared with air, for significant enhancement of thermal insulation.
- The insulated glazing system 1 as shown in the accompanying figures is designed to be mounted to a frame which is in turn adapted to be placed in a wall of a building.
- As used hereinafter, the term “interior of insulated glazing unit” relates to the insulated glazing system 1 as installed, therefore the term “interior of the insulated glazing unit” shall be intended as the closed volume that is defined by the two glass panes at the sides, and by the spacer element above and below, with the terms above and below relating to the lying plane, i.e. the plane in which the insulated glazing system is installed.
- The
spacer element 4 comprises afirst surface 5 designed for coupling with thefirst glass pane 2 and asecond surface 6 designed for coupling with the second glass pane 3. - The
first surface 5 and thesecond surface 6 are parallel and preferably opposite to each other. - In a preferred aspect of the present disclosure, the
spacer element 4 is made of a low heat conductivity material, such as natural or synthetic rubber. - This will provide a
spacer element 4 characterized by a low linear heat transfer coefficient, which will reduce the emission of gas to the atmosphere at the peripheral frame, i.e. where thespacer 4 is mounted. - In other embodiments, the material of the
spacer element 4 may comprise silicone foam and/or the like, or any other commercially available material having similar properties. - The insulated glazing system 1 comprises support means, generally referenced 7, for supporting a blind 8, a screen or the like within the insulated glazing unit, as shown in
FIG. 2 . - The support means 7 consist of a blind assembly installed in the insulated glazing unit and comprise a support box 9 with the blind 8 associated therewith in a manner that is known in the art and will not be further described herein.
- It shall be noted that, for the purposes of the present disclosure, the box 9 of the blind 8 allows the blind to be fixed within the insulated glazing unit.
-
FIGS. 4A to 4C show that thespacer element 4 of the present embodiment comprises amultilayer barrier 18 as a gas and vapor barrier, which covers the outer surface of the spacer element. - The
multilayer barrier 18 is formed as is known in the art, and is made, for instance, of a metal material, such as aluminum, or a multilayer material. -
FIGS. 4A to 4C also show that thespacer element 4 of the present embodiment compriseslateral recesses 19 for receivingseals 20, typically made of butyl (isobutylene, isoprene, polyisobutylene) required in the assembly of the insulated glazing system 1. - It shall be noted that the
lateral recesses 19 are located proximate to thefirst surface 5 and thesecond surface 6 of the spacer element respectively. - Additional
adhesive elements 21 may be provided at the sides of thespacer element 4, i.e. at thefirst surface 5 and thesecond surface 6 of the spacer element. - The
spacer element 4 of the present embodiment comprises, as is known in the art, desiccants such as salts and the like, incorporated therein. - In one aspect of the present disclosure, also referring to
FIG. 2 , the insulated glazing system 1 comprises afirst profile 10 and engagement means 12 and, in a preferred embodiment thereof also asecond profile 11. - Such preferred embodiment of the present disclosure, i.e. the one with the
second profile 11, will be now described. - Particularly, also referring to
FIGS. 4A to 4C , thefirst profile 10 comprises afirst surface 13 designed for coupling with the support means 7 and asecond surface 14 designed for coupling withbottom surface 16 of thespacer element 4. - Particularly, the
second profile 11 comprises afirst surface 16 designed for coupling with atop surface 17 of thespacer element 4. - The
bottom surface 15 and thetop surface 17 of thespacer element 4 are parallel and preferably opposite to each other. - In one aspect, the
first surface 5 and thesecond surface 6 extend substantially perpendicular to thebottom surface 15 and thetop surface 17 of thespacer element 4. - Particularly, also referring to the cross-sectional views of
FIGS. 4A to 4C , it can be noted that thefirst profile 10 is external to the insulated glazing unit, and thesecond profile 11 is internal to the insulated glazing unit, such that they will be opposite to each other on each side of thespacer element 4. Particularly, the first profile is coupled to the bottom surface of thespacer element 4 and the second profile is coupled to the top surface of thespacer element 4. - In one aspect of the present disclosure, the
first profile 10, thesecond profile 11 and thespacer element 4 have each at least one throughhole - In the preferred embodiment, the
first profile 10 thesecond profile 11 and thespacer element 4 comprise each a plurality of through holes, which are shown in the accompanying figures as a series of three holes for each element. - Preferably, the
holes - These through
holes first profile 10, thesecond profile 11 and thespacer element 4 respectively are coaxially formed, which means that when saidfirst profile 10,second profile 11 andspacer element 4 are assembled, theholes - In one aspect, the engagement means 12 engage said through
holes spacer element 4 and thefirst profile 10 and thesecond profile 11. - Particularly, the coupling created by the engagement means 12 will provide both a firm mechanical coupling and an effective seal against gas leakage from the insulated glazing unit as well as against penetration of moisture from outside the insulated glazing unit between the
spacer element 4 and thefirst profile 10 and thesecond profile 11. - It shall be noted that the
first profile 10 comprises a substantially flatcentral portion 10A having twowings 10B extending therefrom. Particularly, the twowings 10B define acavity 10C, i.e. a volume, between the top end of the box 9 and the surface that is coupled to the support means 7. - In one aspect, each of the free tail ends of the two
wings 10B comprise a portion that is specially shaped to create a form-fit with the upper profile of the box 9 to ensure mechanical engagement between the free tail ends of the twowings 10B and the upper profile of the box 9. - It shall be further noted that the
first surface 16 of the second profile 11 (i.e. the surface designed for coupling with thetop surface 17 of the spacer element 4) is complementary to thesurface 17 of thespacer element 4. - In the embodiment as shown in the accompanying figures, the
surface 16 and thetop surface 17 of thespacer element 4 are substantially flat. - Conversely, the
second surface 24 of thesecond profile 11 has an open shape. Particularly, in the central area it extends substantially parallel to thefirst surface 16, whereas the end or peripheral areas are flared, i.e. extend in a direction transverse to the central area. - In one aspect, the
first profile 10 and thesecond profile 11 are made of a rigid material. For example, theseprofiles - Assuming that aluminum is used as a material for the first and
second profiles first profile 10 and thesecond profile 11 will be smaller than the distance between theirrespective glass panes 2 and 3. - Particularly, the width of the first and
second profile second glass panes 2 and 3, which means that thefirst profile 10 and thesecond profile 11 do not contact the twoglass panes 2 and 3. - Such smaller distance ensures that no thermal bridge will be created between the
glass panes 2 and 3 and theprofiles - The
first profile 10, as shown inFIG. 2 , in a preferred embodiment, extends along the entire linear and/or surface extent of the box 9 to overlap or cover its top surface. - Alternatively, the
first profile 10 may be composed of multiple profile sections or lengths. Here, each profile section or length would comprise at least one through hole. - The
second profile 11, as shown inFIG. 2 , in a preferred embodiment, extends along the entire linear and/or surface extent of thefourth surface 17 of thespacer element 4. - Advantageously, by extending along the entire linear extent of the
fourth surface 17 of thespacer element 4, thesecond profile 11 will be able to distribute the weight of the support means 7 and the blind 8, through the engagement means 12, over a larger support surface. - Referring to
FIGS. 4A to 4C , it will be noted that the engagement means 12 comprise sealing means 25 having afirst sealing ring 25A and a second sealing ring 25B, each being placed proximate to the through hole (or through holes) 22, to provide a seal between thespacer element 4 and thesecond profile 11. - In other words, the
first sealing ring 25A and the second sealing ring 25B are placed on thefirst surface 16 and thesecond surface 24 respectively of thesecond profile 11 proximate to the through hole/s 22. - According to one embodiment, the sealing
ring 25A or 25B is made of butylene (isobutylene, isopropene, polyisobutylene). - The sealing
ring 25A or 25B has a thickness ranging from 0.5 mm to 2 mm, preferably of 1 mm. - In one aspect the engagement means 12 comprise fastener means 12′ having a
head end 12A and atail end 12B which are interconnected by a shaft 12C. Preferably, thehead end 12A comprises a countersunk head and thebottom end 12B comprises ratchets that are configured to move from a deployed position to a retracted position. - As shown in
FIGS. 4A to 4C , thehead end 12A engages thesurface 24 at thesealing ring 25A, whereas the shaft 12C and thehead end 12B engage the sealing ring 25B. Particularly, as the shaft 12C and thehead end 12B fit into the throughholes holes - Furthermore, the
tail end 12B of the fastener means 12′ engages thesurface 13 of thefirst profile 10 to thereby create a seal and ensure mechanical engagement. - Alternatively, the fastener means 12′ may consist of screws, rivets or the like.
- The insulated glazing system 1 comprises control means 26 and an associated cord-
puller 26A to control the movement of the blind 8. - In one aspect, as shown in
FIG. 6 , the control means 26 are associated with the glass pane 3 and the box 9 in a manner that is known in the art and will not be further described herein. -
FIGS. 1 to 6 show various details and steps of the assembly of the insulated glazing system 1 having thespacer element 4 and theprofiles - Particularly,
FIG. 1 shows the insulated glazing system 1 without the second glass pane 3 and without the blind 8 and associated box 9, with theprofiles spacer element 4, but with the latter already adhesively bonded to theglass pane 2. - As is shown, screen-printing may be applied to the perimeter end of the
glass pane 2, as well as that of the glass pane 3, to block the perimeter light that might filtrate therethrough and allow the box 9 and theprofiles - On the other hand,
FIG. 5 shows the insulated glazing system 1 in its assembled form, with the blind 8 mounted to the box 9 therein and the second glass pane 3 lifted for clarity. -
FIG. 6 shows the insulated glazing system 1 in its assembled form, with the blind 8 mounted to the box 9 therein and thespacer element 4 adhesively bonded to the glass pane 3 and equipped with control means 26. - As is clearly shown in
FIG. 1 , the insulated glazing system 1 is preferably assembled using asingle spacer element 4 in the form of a closed frame. - Nevertheless, sections of appropriate lengths might also be used.
- In the preferred embodiment, the first profile is placed along the bottom side of the
spacer element 4, and thesecond profile 11 is placed along the top side. - These
profiles spacer element 4 through engagement means 12. Particularly, the fastener means 12′ extend through the throughholes - Alternatively, only the
first profile 10 may be possibly used, with the fastener means 12′ of the engagement means 12 extending through the through holes of thespacer element 4 and thefirst profile 10 only. - The insulated glazing system 1 with the
spacer element 4, the first andsecond profiles - In one step, the spacer element 1, which preferably already has
adhesive elements 21 and seals 20 on both of itssurfaces first glass pane 2 of the insulated glazing system 1, as shown inFIG. 1 , so that a closed frame is formed from a single length ofspacer element 4. - In a preferred aspect, before adhesion to the
glass 2 thespacer element 4 has been punched for a through hole (or the series of through holes) 23 to be formed therein. - Alternatively, the
spacer element 4 may be punched withsuch spacer element 4 already adhesively bonded to theglass pane 2. - Later, as shown in
FIG. 2 , thespacer element 4 is associated at its bottom side with thefirst profile 10, that has been coupled beforehand to the support means 7, and at its top side with thesecond profile 11. - In a preferred embodiment, the first and
second profiles - Preferably the first and
second profiles second profiles first profile 10 will have the same center-to-center spacing as that of the through holes formed in thesecond profile 11. - In one aspect of the assembly, the sealing means 25 are placed proximate to the through hole/s 22 of the
second profile 11 and the fastener means 12′ are fitted into these through holes. - Then the through
holes second profile 11. - Particularly, the
head 12B fits into thehole 22 of theprofile 11, extends through thehole 23 of thespacer element 4 and comes out of thehole 21 of theprofile 10, where it engages with thesurface 13 ofsuch profile 10 to fasten thefirst profile 10 and thesecond profile 11 to thespacer element 4. - Therefore, the fastener means 12′ act as guide elements when coupling the various components, to ensure that the through holes will be coaxial.
- The second glass pane 3 will be finally attached to the spacer element 1 by means of
adhesive elements 21 and seals 20. - The description clearly shows that the invention so conceived provides important technical advantages.
- First, the
spacer element 4 affords all the advantages that can be obtained with conventional “warm edge” systems, in terms of reduced emissions to the outside, i.e. power savings, as well as the possibility of simply, quickly, safely and cost-effectively mount any blind, screen or the like in the insulated glazing system. - Those skilled in the art will obviously appreciate that a number of changes and variants may be made to the above described insulated glazing system and associated assembly method, to fulfill particular requirements, without departure from the scope of the invention, as defined in the following claims.
