Definitions

• the present invention relates to a device in spacers intended for apply • ing between the edge part of a sealed insulating glass unit and the sur ⁇ rounding window frame or casement for carrying or steadying the unit in spaced relationship with the frame or casement.
• spacers are used between the edge part ' thereof and the frame or casement not only for carrying the unit,but for steady ⁇ ing it laterally in the case of side-hung windows.
• the task of the space is to distribute the gravity forces between the unit and frame or case ⁇ ment in a controlled manner so that all the panes included in the sealed insulating glass unit take up substantially equally as great compression forces.
• the spacers used so far usually comprise an elongate, strip-like part, the width of which somewhat exceeds the thickness of the unit.
• the spacers have pinning means for retaining the spacer in place after fitting a glazing strip, so that the spacer does not glid down along the rebate aid collect in the vicinity of the lower corner of the unit, there has been the problem that it has not been possible to fit sealing strips after fitting the glazing strip; Since they are ⁇ substantially uniformly thick in their longitudinal direction, the pin ⁇ ning means have then become bent and have caused gaps in the sealing strip, with consequential leakage. Since the pinning means are upwardly blunt, this fitting of sealing strips with movement parallel to the glass surface in a direction towards the frame has not been able to be carried out. In the cases where these uniformly thick pinning means have retained full height after fitting a sealing strip, they have forced away the sealing material at their tips and gaps have then been formed in the sealing strip with consequential damage to the window structure.
• the object of the present invention is to provide a device in spacers of the kind mentioned in the introduction, in which the drawbacks per ⁇ taining to present spacer means have been mitigated without resorting to gluing or other troublesome operations for keeping the spacers in place, while at the same time enabling later fitting of sealing strips after the glazing strips have been fitted.
• the inventive spacer is provided with tongue-like retaining means which have tapering or knife-like con ⁇ figuration at their free ends.
• sealing strips can be very readily pressed down into the gap between the unit and glazing strip, by the tips of the retaining tongues being press inwards towards the glass of the unit or the glazing strip so as not to prevent thrusting the sealing strip into the mentioned gap.
• the retaining tongues are strongest where the stresses are greatest, i.e. at the junction between tongue and spacer.
• the greatest thickness of the tongues can be allowed to provide spaced relationship between the unit and the position of the glazing strips.
• the compression of the sealing strip can be varied depending on how large a thickness of the lower part of the retaining tongue is .--.elected.
• Figure 1 is a perspective view of a spacer in accordance with a first embodiment of the present invention
• Figure 2 is an end view of the spacer illustrated in Figure 1 and Figure 3 is a cross section of a second embodiment of a spacer in accord ance with the invention, showing the spacer fitted in a frame.
• the spacer 1 includes a strip-like body, the width of which is in substantial agreement with the width of a sealed insulating glass unit.
• This body comprises two longitudinal, parallel ribs 2 and 3, which are connected to each other with the aid of a plurality of trans- " verse members 4 constituting a centrally situ ⁇ vted web part.
• the thick ⁇ ness of the central part 5 of the members 4 is less than the thickness of the ribs 2, 3, thus forming a draining channel 6 for removing mois ⁇ ture or condensation, which can otherwise destroy a window structure.
• the spacer has at least on one long side 7 at least one retaining tongue 8 for locating the spacer 1 in its position between a sealed insulating glass unit 9 and a frame 10 by clamping the tongue 8 between the unit 9 and a surrounding frame 10 or between the unit 9 and a glazing strip 11, depending on how the spacer 1 is fitted, or whether the tongues 8 are only along one long side 7 of the spacer 1.
• the tongue 8 has optional width in the longi ⁇ tudinal direction of the spacer 1, but a thickness which decreases to- wards its free end 12 to terminate in a knife-like configuration.
• the lower part 14 of the tongue 8 can be given optional thickness, thus en ⁇ abling determination beforehand of the spaced relationship between glaz ⁇ ing strip and unit or unit and surrounding frame 10.
• a sealing strip 13 can then be thrust between the glazing strip 11 and unit 9.
• the tongue 8 can be formed such that one side of it is flat while the other curves inwardly such that the tongue has a knife-edge configuration at its free end 12.
• the tongue can be angled in either direction just before the knl e-edge, depending on whether it ' shall come tightly agains the unit 9 or the glazing strip 11, and its tip can have a chisel-like configuration.
• the embodiment of the spacer 1 illustrated in Figure 3 has the tongue 8 with a knife-edge configuration leaning towards the unit 9.
• the glazing strip 11 is here formed with a recess 15 for coaction witii a bead 16 projecting from a sealing strip 13 which can be thrust down against the unit 9. How spaced relationship is achieved between the glazing strip 11 and unit 9 is also apparent from the thickness 17 of the tongue 8 at its lower part 14.
• the lower part 14 of the tongue 8 also serves here as a spacer between. the unit 9 and glazing strip 11. It is also possible for the tongue 8 to pierce the sealing material in the sealing strip 13 or enter a gap in the glazing strip 11, if so desired, but this was quite impossible with previously known structures.
• the retaining tongue 8 By the implementation of the retaining tongue 8, a movement in fitting the glazing strip obliquely or straight from above is permitted both when the glazing strip has integrally formed sealing strips and when it does not. This is the case, particularly in special section structures which are formed into window frames.
• the inventive concept for the im ⁇ plementation of the spacer 1 is thus that it is retained by the retain ⁇ ing tongues 8 through contact with a glazing strip and/or a sealing strip insertable from the glazing strip or between the strip and the unit 9, while the retaining tongue 8 is kept intact after fitting.
