The profiles are connected by plug-in connectors 1 comprising first limbs 5 and second limbs 5a for insertion into the ends of two profiles, preferably at a corner, wherein each limb comprises a series of engaging means 10, 10a, 11, 11a, preferably in the form of parallel ridges (figure 2) and of a saw-tooth shape, arranged to co-operate with the protuberances 36, 37 of the profiles 30 to releasably connect them. The spacing between adjacent engaging means is less than the spacing between adjacent protuberances.
Description
Window or Door Spacer Frame
The present invention relates to a spacer frame for a window or door.
A spacer frame is used to space apart the glass sheets of a double or triple glazed window or door and is formed from two or more hollow spacer bar sections, hereinafter referred to as profiles. The profiles are perforated on the face exposed to the window cavity in order to allow moisture to pass freely from the window cavity into the profile.
A desiccant is often contained in the profile to absorb the moisture.
For most glazing applications, four profiles are required to fabricate a rectangular unit. In this case, four corner-key connectors are used to connect the respective ends of the profiles. If the corner joints are integrally formed in the profile, then a linear-key connector may be used.
Commercially available connectors tend to be of the plug-in variety and these are designed to be inserted into the profiles with the minimum of force, whilst still providing secure retention. This is necessary in order to maintain integrity of the frame during handling prior to assembly. It is, of course, also important that the spacer frame can accommodate dimensional tolerance variations, particularly of the profile housing.
GB-B-2 269 845 describes a spacer frame comprising a connector which has an interference action fit with the side-walls of the profile. The connector preferably has a U-shaped section. The internal space of the connector is optimised to provide a large through-passage for desiccant during filling.
WO 92/2702 and EP-B-0 283 689 also describe connectors having a U-shaped section. These have sharp projections pressed out of the limbs and the cross-web of the U to engage the side-walls of the profiles.
We have now developed an improved and particularly positive retention system which relies on the structural form of the profile once it has been perforated. The perforations are typically partpierced or punched in a fashion that leaves dimples in the external face of the profile with corresponding protuberances on the internal face. We have found that the protuberances on the internal face are ideal for co-operating with a plug-in connector.
Accordingly, in a first aspect the present invention provides a spacer frame for a window or door including two sheets of glass spaced apart to define a window cavity therebetween, the spacer frame comprising a hollow profile having two ends to be connected and a series of perforated protuberances on the inner surface of a wall thereof, which wall is exposed to the window cavity in use, and a plug-in connector comprising first and second limbs for insertion into the ends of the profile, wherein each limb comprises a series of engaging means arranged to co-operate with one or more of the protuberances adjacent to the said ends thereby to releasably connect them, and wherein the spacing between adjacent engaging means is less than the spacing between adjacent protuberances. In this aspect of the invention, one hollow profile may be used which can be formed to the shape of the window or door and the ends connected. For most applications, however, there will be at least two hollow profiles to be connected and, accordingly, in a second aspect, the present invention provides a spacer frame for a window or door having at least two sheets of glass spaced apart to define a window cavity therebetween, the spacer frame comprising two or more hollow profiles to be connected, each profile having a series of perforated protuberances on the inner surface of a wall thereof, which wall is exposed to the window cavity in use, and two or more plug-in connectors, each connector comprising first and second limbs for insertion into respective ends of the profiles to be connected, wherein each limb comprises a series of engaging means arranged to co-operate with one or more of the protuberances adjacent to the said ends thereby to releasably connect the profiles, and wherein the spacing between adjacent engaging means is less than the spacing between adjacent protuberances.
The feature concerning the spacing between adjacent engaging means is an important feature, since if the spacing is equal to or greater that the spacing between adjacent protuberances, then co-operation between the various features can be insufficient to reliably secure the plug-in connector(s) in the ends of the profile(s). When the spacing between adjacent engaging means is less than the spacing between adjacent protuberances, the likelihood of co-operation between a protuberance and a complimentary engaging means is increased and hence a reliable and secure connection is achieved.
For the avoidance of doubt, by the term series of perforated protuberances is meant two or more perforated protuberances; and by the term a series of engaging means is meant two or more engaging means.
The engaging means of the first and second limbs may comprise raised portions on a surface thereof, recesses in a surface thereof or a combination thereof. Advantageously, the raised portions comprise a series of substantially parallel ridges which extend in length in a direction substantially perpendicular to the direction of insertion. To facilitate insertion, one or more of the ridges is/are preferably ramped away from the free ends of the limbs. If the engaging means include recessed portions these may comprise a line of dimples extending in a direction substantially parallel to the direction of insertion.
A profile typically comprises two rows of parallel side-by-side, i.e. aligned, perforations. In this case, the first and second limbs advantageously comprise first and second rows of engaging means, wherein the second row extends substantially parallel to the first row and is displaced relative thereto in the direction of insertion to provide a degree of misalignment between neighbouring engaging means of the first and second rows.
The protuberances in a profile are typically substantially equally spaced and, consequently, the engaging means of each of the two limbs of the connector may also be substantially equally spaced.
However, in the case where the first and second limbs comprise first and second rows of engaging means, the spacing between adjacent engaging means in the second row may differ from that in the first row.
The ratio of the spacing between adjacent protuberances to the spacing between adjacent engaging means is preferably in the range of from about 2:3 to about 2:5, more preferably about 5:8. A typical protuberance spacing is about 4 mm.
For applications requiring a corner-key plug-in connector, the first and second limbs will be substantially perpendicular to one another. In this case, the spacer frame will comprise four hollow profiles and four plug-in connectors. On the other hand, if the corner joints are integrally formed in the profile, then the first and second limbs of the plug-in connector will be substantially axially aligned. It will be appreciated that a combination of corner-key connectors and axially aligned connectors may be used depending upon the application.
To further improve retention of the plug-in connector in the ends of the profile, the plug-in connector may be sized for frictional engagement with one or more of the inner surfaces of the profiles.
Advantageously, each limb of the plug-in connector further comprises a plurality of supporting ribs which frictionally engage one or more of the non-perforated walls of the profile(s).
The profiles are typically formed from aluminium or an alloy thereof and the plug-in connector is preferably formed from a resilient plastics material.
The plug-in connector may be injection moulded from, for example, a polyamide, ABS, polypropylene or polyester.
It will be appreciated that a desiccant material can be provided in the hollow profiles to absorb moisture.
The present invention also provides a double or triple glazed window or door including a spacer frame as herein described.
The present invention also provides a plug-in connector for releasably connecting hollow profiles in a spacer frame for a window or door in which each profile has a series of protuberances on the inner surface of a wall thereof, the plug-in connector comprising first and second limbs for insertion into respective ends of the profiles to be connected, wherein each limb comprises a series of engaging means arranged to co-operate, in use, with one or more of the protuberances adjacent the said ends, and wherein the spacing between adjacent engaging means is less than the spacing between adjacent protuberances.
The present invention will now be described further, by way of example, with reference to the accompanying drawings in which:
Figure 1 is a side-view illustration of a plug-in connector for use in the spacer frame according to present invention;
Figure 2 is a plan-view of the plug-in connector illustrated in Figure 1;
Figure 3 is a plan-view of a profile for use in the spacer frame according to the present invention;
Figure 4 is a horizontal cross-section through the line AA' of the profile illustrated in Figure 3; and
Figure 5 is a vertical cross-section through one of the punched perforations in the profile of Figure 3.
In Figure 1, a plug-in connector 1 of the cornerkey variety is shown having first 5 and second 5a limbs which are perpendicular to one another. A series of engagement means comprising a plurality of ridges, such as those shown at 10 and 11, are provided on surface 12 of the first limb 5. Similarly, ridges such as those shown at 10a and lla are provided on surface 12a of the second limb. The ridges 10, 11 and 10a, lla are ramped away from the free ends 20 and 20a, respectively, of the first 5 and second Sa limbs.
The upper surfaces of ridges 10, 11 and 10a, lla are flat and the ridges accordingly describe a blunted saw-tooth profile. The ramped surface and upper flat surface of ridge 10 are shown at 14 and 15 respectively. With reference to Figure 2, it can be seen that the engagement means on surface 12 of the first limb 5 comprises two parallel rows of ridges.
The rows are displaced relative to one another so that ridge 10, for example, in the first row is misaligned with respect to neighbouring ridge 13 in the second row. The ridges in each row are substantially equally spaced and the gap between adjacent ridges 10 and 11 in the first row is shown at 18. Advantageously, the ridges in the second row are misaligned with respect to ridges in the first row to the extent that they are substantially out of phase, i.e. they are substantially aligned with the gaps between the ridges in the first row.
To facilitate insertion into the ends of a profile, the regions in the vicinity of the free ends 20 and 20a are tapered, having inclined surfaces 21 and 21a respectively, and mutually converging walls 22 and 23 (as shown for limb 5 in Figure 2).
Angled supporting ribs such as those shown at 24 and 24a extend outwardly from the surfaces opposing surfaces 12 and 12a, respectively. The supporting ribs 24 and 24a are inclined away from the free ends 20 and 20a (apart from the supporting ribs furthest away from the free ends) to facilitate insertion. A generally square abutment ridge 25 is provided at the intersection of the first 5 and second Sa limbs.
A conventional spacer bar section or profile is illustrated in Figures 3, 4 and 5. The hollow profile 30 is of generally rectangular crosssection with a pair of opposed inclined shoulders 31 and 32. Two parallel rows of substantially equally spaced punched perforations, such as those shown at 36, 37 and 38, are provided in the wall 33 (which faces the window cavity in use). The gap between adjacent perforations 37 and 38 in one of the rows is shown at 39. Gap 39 is greater than gap 18 (the gap between adjacent ridges 10 and 11 in the first row of ridges on the first limb 5).
The perforations are shown in greater detail with reference to Figures 4 and 5, where it can be seen that the mechanical punching operation has resulted in a dimple 40 in the outer surface 34 and a corresponding protuberance 41 on the inner surface 35 of the wall 33.
In use, the limbs 5 and 5a of the plug-in connector 1 are inserted into the respective ends (not shown) of two profiles to be connected. Ridge 25 abuts with the edges of the ends of the profiles and prevents the plug-in connector 1 being inserted any further. The size of the plug-in connector 1 and the arrangement of ridges 10, 11 and 10a, lla are chosen such that one or more the ridges co-operate with one or more of the protuberances adjacent the end of each of the profiles, thereby releasably connecting the profiles. It will be appreciated that the protuberance 41, for example, may engage one or both of surfaces 14 and 15 of the ridge 10 and/or the adjacent portion of surface 12 in gap 18.
Since gap 18 is less than gap 39, the likelihood of co-operation between a protuberance 41 and a complimentary engaging ridge 10, 11 and 10a, lia is increased and hence a reliable and secure connection is achieved. The misalignment between the two rows of ridges further improves the likelihood of co-operation between complimentary features.
To further improve retention of the plug-in connector 1, the supporting ribs 24 and 24a are shaped and sized so that they frictionally engage with one or more of the non-perforated walls of the profile 30.
The present invention provides an improved and particularly positive retention system which relies on the structural form of the profile once it has been perforated. Reliance on the protuberances on the internal face of the profile provides for an elegant and simple connection. By limiting the spacing between adjacent engaging means, the likelihood of cooperation between a protuberances and a complimentary engaging means is increased and hence a reliable and secure connection is achieved, particularly if two misaligned rows of engaging means are used.
