The plastic materials may be transparent and UV stable. Flat surfaces of the base may be secured to adjacent edges 2 of panels to connect them edge to edge with their plane surfaces 4 aligned. Each longitudinal edge of the base may have a pair of opposing fins for sealing against chamfers on the panels. The fins may be perpendicular to the base, or angled slightly towards each other. The base may be secured to the panels by tape 10. The strip may be formed by co-extrusion.
Description
SEALS AND CONNECTORS FOR GLASS PANELS
This invention relates to seals and connectors for glass panels and partition assemblies.
Using glass for partition, especially in offices, has become increasingly common in recent years. The appearance of such installations has also become more important, with the result that connectors and seals used are required to be optically (glass) clear and UV stable to provide a consistent seamless appearance. The connectors and seals need to combine an aesthetic appearance with appropriate sealing and acoustic properties. It is also an advantage if they are easy to install. However, glass panels typically have chamfered edges, pr manly for safety reasons, and the size and angle of the chamfers can vary considerably.
It is known to provide seals connecting adjacent glass panels by mastic or plastic strips. Mastic can provide a relatively neat appearance, but is time-consuming to apply, and tends not to be optically clear. Plastics strips are usually relatively; rigid, and in order to accommodate variation in the chamfers of the panel edges typically are H-shaped, with scaling flanges overlapping onto the plane surface of thc glass panels.
This provides a convex joint which detracts from the appearance of the assembly, even if the material is optically dear.
According to the present invention there is provided a strip for sealing the gap between a first glass panel and a second glass panel adjacent the first glass panel. the strip being formed from two plastic materials, and comprising a base portion of relatively rigid material adapted to be secured to both glass panels, and at least two fins of flexible material, each fin projecting from a longitudinal edge of the base portion, a first fin being adapted to seal against a chamfer on an edge of the first glass panel, and the second fin being adapted to seal against a chamfer on an edge of the second glass panel.
The relatively rigid base portion ensures that the strip can be securely engaged with the glass panels. As the fins engage and seal against the chamfers, the joint will be in the plane of the surface of the glass panel, or slightly concave, so that it presents a neat appearance. The flexible nature of the fins means that they can seal against chamfers formed at different angles. The strip is also quicker and easier to install than mastic.
Preferably both materials are optically (glass) clear and internal UV stable. This enhances the appearance of the join.
The first and second glass panels may be connected edge to edge, with their plane surfaces aligned. The base portion is then secured to the adjacent edges of the panels.
Each longitudinal edge of the base portion has a pair of opposing flexible fins. A first fin of each pair of fins may be adapted to seal against a chamfer on an edge of the first panel, and a second fin of each pair of fins may be adapted to seal against a chamfer on an edge of the second glass panel. The strip is therefore substantially I-shaped.
Preferably, the base portion has flat surfaces for securing to the panels.
The plane surfaces of the panels are aligned. Preferably, the base portion is flat, and perpendicular to the aligned planes of the panels, and the fins project substantially perpendicularly or angled towards each other by a few degrees.
The base portion may be provided with adhesive tapes, by which the strip can be secured to the glass panels. The tape is also optically glass clear and UV stable. It may be protected by a peel-off strip.
Conveniently the base portion is of a glass clear rigid polymer. The fins are of a glass clear flexible polymer. The strip is extruded from the plastics materials. The strip is preferably formed by co-extrusion of plastics materials.
An embodiment of the invention is illustrated, by way of example only, in the accompanying drawings, in which:-Figure 1 is a perspective view of a strip according to the invention; Figure 2 is a cross-section through the strip of Figure 1; Figure 3 is an end view of the strip attached to one glass panel; and Figure 4 is an end view of the strip attached to two adjacent glass panels.
The strip 1 shown in the drawings is designed to provide a mechanical join and a seal between the respective edges 2 of a pair of adjacent glass panels 3, which are stationary. The strip 1 is secured to both the panels 3, which as shown in Figures 3 and 4, are arranged with their plane surfaces 4 aligned. Each edge 2 of each panel 3 has a corner chamfer 5. Chamfers 5 can vary in size and angle because of differences between the manufacturers and manufacturing tolerances. The strip 1 is designed to seal a range of corner chamfers 5.
The strip 1 is co-extruded from two different plastics materials, each of which is optically (glass) clear and internal UV stable. One of the materials is a relatively rigid plastics polymer material and the other is a more flexible and resilient plastics polymer material. The plastics are different types of polyethylene terephthalate glycol-modified (PETG).
As best seen in Figure 2, the strip 1 comprises a flat base portion 6 of the rigid material, and four fins 7 of the flexible material projecting from the longitudinal edges 8, 9 of the base portion 6.
The width of the base portion 6 is chosen to be slightly less than the thickness of the glass panels 3. The base portion 6 has an adhesive tape 10 on each side II, 12, by which it is attached to a respective panel 3. The adhesive tape 10 is a high bond adhesive and is also optically (glass) clear and internal UV stable. The inner adhesive face 13 of each adhesive tape 10 is attached to the respective side I I, 12 of the base portion 6, and the outer adhesive face 14 is protected by a peel-off strip 15.
Each fin 7 is designed to seal with a corner chamfer 5 on a glass panel 3. A strip 16 of the flexible material extends across each longitudinal edge 8, 9 of the base portion 6. Each strip 16 forms a pair of fins 7 projecting in opposite directions from the base portion 6. The fins 7 project perpendicularly from the base portion 6. Each is designed so that the inner edge 17 of its free end 18 engages with and seals on a chamfer 5. Because of the flexibility of the fins 7, they can accommodate a range of corner chamfers 5.
The strip 1 is manufactured by co-extrusion of the rigid and flexible plastic polymer materials The tapes 10 are applied to the base portion 6 as part of the extrusion process. Although it would be possible for the base portion 6 to be formed from the flexible material, as it is not required to be rigid in use, in practice it is preferable to form it from the rigid material, so that it is easy to apply the adhesive tapes 10, and easier to handle for fitting.
For use, the strip 1 is cut to the appropriate length, joins in the strip 1 being avoided as these can detract from the appearance. The peel-off strip 15 is then removed from the tape 10 on the side 11 of the base portion 6, enabling the outer adhesive face 14 of that tape to be applied to the edge 2 of a first one of the panels 3, as shown in Figure 3. The fins 7 projecting from the side 11 engage with the corner chamfers 5 on that panel 3, with their inner edges 17 of the free ends 18 sealing with the respective chamfers 5. The peel-off strip 15 is then removed from the tape 10 on the side 12 of the base portion 6, so that the strip 1 can similarly be attached to the adjacent edge 2 of the second panel 3, with the fins 7 projecting from the side 12 engaging and sealing with the corner chamfers 5 on the second panel, as shown in Figure 4. The corner chamfers 5 on the second panel are different from those on the first panel, so that the fins 7 assume a slightly different configuration.
The strip 1 provides both a mechanical join and a seal between the adjacent edges 2 of the panels 3. It will be noted that the joint is substantially concave, so that it presents a neat appearance, even where the fins 7 have different configurations due to differences in the chamfers 5. The flexibility and resilience of the fins 7 ensures that they will always provide a neat appearance and a good seal with the glass panels 3.
