Description

DEVICE FOR MANUFACTURING OF GAS-INSULATED WINDOWS
TECHNICAL FIELD
The present invention concerns a device for a later improvement of the insulating property at a window by providing the same with an extra pane inside an exis¬ ting window pane and making tight joints between these window panes and to fill the space between these panes with an insulating gas. BACKGROUND ART
From the Swedish patent publication SE-C-339 990 it is earlier known a method for an eventual later im¬ provement of the insulating property at a window by pro¬ viding the same with an extra window pane inside the existing window pane. In order to achive tight joints between these window panes a garter strap is placed in¬ side the existing window pane and this garter strap is brought to run along the window frame around the complete pane. In a corner of the window frame the two end por- tions of the garter strap are led out from the window.
After that a corner of the extra pane is cut off and the latter is places in that way that the ends of the garter strap can pass from the window by the opening from the cut off corner in the extra pane. At last a resistance wire in the garter strap is connected to an electrical source and in that a' voltage is fed to the resistance wire the garter strap is heated in several turns, that is two times in order to heat the garter strap to make it soft and one time to harden the same. From the British patent publication GB-A-1 506
282 it is earlier known to manufacture insulated windows at which a frame of a current-conducting material is placed between two panes and to heat the frame by connec¬ ting two contact means from a current source to the same. By this heating of the frame the jointing masses between the frame and the panes is heated and caused to melt.
From the Swedish patent publication SE-C-455 620 it is also known a method permitting a fast mounting of extra panes and resulting in a window with a considerably improved insulating property but what was present at the window before the completion with the extra pane. By pla- cing the used frame and the extra window pane on blocks in this method a gap is achieved at which contact means from a current source are brought into the space between the extra frame and the window frame to be connected to the extra frame. This gives the advantage that the extra frame easily can be reached by the contact means and these easily can be fastened between the extra frame and the window frame. Further the contact means can be brought into the space at different locations along the extra frame, which is to prefer if a partial heating of a part of the extra frame is demanded. The extra frame also gives large contact surfaces for the jointing masses and also a distance means between the panes, by which the latter easily can be brought in parallel. At last the gap between the extra frame and the window frame is provided with a jointing mass, by which is ensured a very effec¬ tive insulating also around the complete extra frame and also between the extra frame and the panes. DESCRIPTION OF THE INVENTION
The purpose with the present invention is a fur- ther improvement of the method for manufacturing of win¬ dows with insulating pane which is described in SE-C-455 620. The purpose has been achieved with a device accor¬ ding to the present invention to improve the insulating property of a window afterwards by providing the same with an extra window pane inside an existing window pane and to achieve tight joints between these window panes. A current-conducting frame with' an inner and an outer strip of a jointing mass is placed between the window panes, the extra frame and the extra window pane are placed on blocks below, which are placed on an existing window frame in the window. The contact means from a current source are brought into a gap between the window frame and the extra window pane placed in the window pane by a gap running around the extra window pane. The contact means are brought into contact with the extra frame for heating of the same and of the jointing masses. The de- vice is characterized in that an insulating gas after that is brought into the space between the window panes by at least one gas-supplying means until the gas pene¬ trates from at least one venting means, after which the gas-supplying means and the venting means are closed, and that a jointing mass is injected between the extra frame and the window frame after that the contact means and " eventual another supply means for insulating gas and venting means are removed. More characterizing features will be clear from the claims. DESCRIPTION TO DRAWINGS
The invention is described below by examples regarding to the enclosed drawings.

Figure 7 illustrates the same section after heating and completed filling with jointing mass in the- gap between the extra frame and the window frame* Figure 8 illustrates in a perspective view a window with an inlet for filling of gas and an outlet for air.
Figure 9-11 shows filling devices for gas brought into the extra f ame.
In figure 1 is illustrated a window 1 consisting of a window framing 2, an outer window frame 3 with an outer window pane 4 and an inner window frame 5 with an inner window pane 6. The insulating property of the win- dow 1 is afterwards improved by providing the same with an extra window pane 7, a so called insulating pane, • which is located inside an extra frame 8 which in its turn is placed inside the inner window pane 6 seen from the inside of a room. The extra frame 8 is consisting of four parts which are assembled by means of corner pieces 9, and each part of the frame shows hollow sections with openings 10, which are intended to give a connection bet¬ ween the space between the inner window pane 6 and the extra window pane 7 and a drying agent 11 , located inside the extra frame 8. The extra frame 8 shows an inner strip of jointing mass 12 constituting a joint 13 between the extra frame 8 and the inner window pane 6, and the extra frame 8 also shows an outer strip of jointning mass 14, constituting a joint 15 between the extra frame 8 and the extra window pane 7. Between the extra frame 8 and the inner window frame 5 blocks 16 are placed and the gap between the extra frame 8 and the inner window frame 5 is filled with a jointing mass 17. At last an ornamental moulding is arranged to cover the gap between the extra window pane 7 and the inner window frame 5.
In order to quickly and effectively achieve the air-tight joints 13, 15 an extra frame 8 of electrically conducting material is used, i.e. the extended parts of the extra frame 8 as well as the corner pieces 9 are made of an electrically conducting material in the way that a current can. be conducted arround the extra frame 8 as a whole and heat the same by its inner resistance. In this case the jointing mass 12 and 14 is constituted by a mass traded under the name BUTYL. This jointing mass 12 and 14 is brought on the extra frame 8 before delivery and this suitably is made by means of nozzles (not shown), the BUTYL-mass is heated to 110 - 190 °C + 10 °C, i.e. to a temperature below the melting point of the BUTYL-mass, which melting point is 220 ° - 280 °C. At delivery the jointing masses 12,
14 are protected by protective strips 19, 20. At delivery the openings 10 of the extra frame 8 are covered by a protective strip 21 to prevent the drying agent 11 to penetrate.
After removing of the protective strips 19, 20,
21 the extra frame 8 is pressed against the inner window pane 6 (see the dotted position in figure 3), after which the extra window pane 7 is placed on the same blocks 16 below, carrying the extra frame 8 below (see figure 4).
By the adhesion force of the jointing masses 12, 14 the extra frame 8 will stick upon the inner window pane 6 and the extra window pane 7 will stick upon the extra frame 8 without any extra steps.
In order to achieve completely tight joints 13,
15 between the extra frame 8 and the inner window pane 6 and the extra frame 8 and the extra window pane 7 two contact means 22 are brought through the gap 24 between the extra window pane 7 and the inner window frame 5 in a space 25 between the extra frame 8 and the inner window frame 5. The contact means 22 preferably are placed at diagonally opposite corners to have the current to pass the complete extra frame 8, but can also be placed about at the centre of the lower part of the extra frame 8 and about at the centre of the upper part of the frame or about at the centre of the one vertical portion and about at the centre of the other vertical portion of the extra frame 8.
After that the extra frame 8 and the extra win¬ dow pane 7 are arranged and heated firmly upon the original inner window pane 6 the space between these two window panes is filled up by a heat-insulating gas as e.g. argon. For this purpose the extra frame 8 is provi¬ ded with two mainly diagonally arranged gas hoses 29, 30 of which the lower gas hose 29 is used for providing in¬ sulating gas and the upper gas hose 30 is used to lead away the air which is forced away of the insulating gas as this is brought into the space between the window panes 6, 7. The insulating gas is provided to the lower gas hose 29 from a gas holder 31 by a hose connection 32. The lower gas hose 29 extends through the tight casing of the extra frame 8 and into its space containing the po¬ rous moisture absorbing drying agent 11. By means of a gas indicator 33 is indicated when the space between the window panes 6, 7 is completely filled up whith insula¬ ting gas and this gas starts escaping through the upper gas hose 30 and activates the gas indicator 33- In order to speed up the gas-filling of the space between the win¬ dow panes 6, 7 further the upper gas hose 30 can be con- nected to a vacuum device, which preferably is connected' after the gas indicator 33- The supply of insulating gas is carried out whith a pressure just above the atmosphere pressure in order not to expose the extra window pane 7 for forces which can cause leakage in the strips of join- ting mass 12, 14 or cracks in the glass. As the space between the window panes 6, 7 is completely filled up with gas the supplying of gas is cut off. The gas indica¬ tor 33 is removed and the upper gas hose 30 is closed e.g. by heat welding or filling with a jointing mass as e.g. a silicon mass. After that the hose connection 32 to the gas holder 31 is removed after which also the lower gas hose 29 is closed in the same way.
In an alternative embodiment of the invention the gas hoses 29, 30 can be replaced by tubular gas-con- ducting means 26, 27 made of plastic, as shown in figure 8 and 9, for the supply of gas respectively venting through the gas-tight casing of the extra frame 8. Each gas-conducting means 26, 27 shows a nozzle 28 which is brought into a hole in the extra frame 8. In the case when the extra frame 8 shows inner gas-tight sections e.g. at the corners of the extra frame 8 the nozzle 28 only can be brought through the outer rim and end inside the extra frame 8 as shown in figure 9. The insulating gas can not pass the gas-tight sections but be forced to penetrate the openings 10 in the inner rim of the extra frame 8. In the case the extra frame does not show inner gas-tight sections as e.g. as the inner frame 8 is manu¬ factured by bending from one and the same section the nozzle 28 can be brought across the extra frame 8 as shown in figure 10. By placing gas-tight sections at de¬ sired places in the extra frame 8 also the gas-conduc- ting means 26, 27 (also the gas hoses 29, 30) can be brought into the extra frame 8 optionally. In order to arrange the extra frame 8 as close to the window frame 5 as possible the gas-conducting means 26, 27 are made with the lowest possible overall height in the gap 24 between the extra window pane 7 and the window frame 5. The tubu¬ lar gas-conducting means 26, 27 by that preferably are arranged in each hole in the extra frame 8 before this is mounted on the excisting window pane and turned out per¬ pendicular from the extra frame 8. After the gas-filling the gas-conducting means 26, 27 are cut off in the same way as the gas hoses 29, 30 and sealed.
In an alternative embodiment of the invention the supply of gas can be done by a gas supply nozzle 34, as shown in figure 9, and the venting is done by e.g. a gas hose 30 and a gas indicator 33. The gas supply nozzle 34 preferably shows a conical seat which is brought into a lower hole in the extra frame 8 and kept in the gap 24 between the extra window pane 7 and the inner window frame 5 by means of a tightening device 35 showing spring-loaded, away from each other acting shanks 36, 37. A one shank 36 is tubular and carries the gas supply nozzle 34 and is also connected by a hose connection 32 to the gas holder 31. The hole in the extra frame 8 can be provided with an automatically closing nonreturn valve, not shown in the figures.
The openings 10, mentioned before, on the side of the extra frame facing the gas-filled space preferably can be replaced by a longitudinal gap between the two facing plate edges in the extra frame 8 after its bending to a desired cross section. This gap is a natural opening for gas penetrating the lower gas hose 29 or the corre- sponding nonreturn valve at filling, or for the eventual moisture which is to be absorbed of the drying agent 11 during the life-time of the window. In order to facili¬ tate the gas filling the drying agent 11 preferably can be excluded in the lower respectively the upper portion of the extra frame 8 and only the vertical side portions filled with the drying agent 11. The gap or the corre¬ sponding openings 10 in the lower respectively the upper portion of the extra frame 8 thus can be made wider as no drying agent 11 is present which can penetrate. After finished jointing and gas-filling a join¬ ting mass 17 (e.g. a silicon mass traded under the name SILPRUF 584,585) is injected in the space 25 and the gap 24 until these are completely filled up (see figure 7). At last the ornamental moulding 18 is mounted and this can e.g. be kept in place by the adhesion ability of the silicon material.
The extra frame 8 can be constituted of any kind of material, e.g. steel, with an electrical conducting ability or the portions of the extra frame, constituting a base for the jointing masses, can be of an electrical conducing material, whilst other portions of the extra frame can show bad or have no electrical conducting abi¬ lity. The extra frame 8 alternatively can have •another section but that described above. The joining masses 12, 14 can be of any kind of suitable jointing material but
BUTYL or made of another kind of BUTYL but that described above. The jointing mass 17 can be another but silicon.
