Abstract

An installation system to fabricate the multiple glazing units at the installation site is provided. The installation system includes a primary glazing unit, a secondary glazing unit, a spacer element, a primary sealant, a fixture, a secondary sealant and a dispenser. The installation system includes a fixture to apply the primary sealant on the spacer element. The installation system also includes a dispenser to apply the secondary sealant to a clearance between the primary glazing unit and the secondary glazing unit.

First claim

What is claimed is:

1. An installation system for fabricating multiple glazing units at an installation site, the installation system comprising:
at least a primary glazing unit;
at least a secondary glazing unit;
a spacer element aligned there between at the periphery of the primary and secondary glazing unit, wherein the spacer element comprising a first surface and a second surface, the second surface is opposite to the first surface, the first surface is configured to be attached to the primary glazing unit and the second surface is configured to be attached to the secondary glazing unit;
a primary sealant;
a fixture to apply the primary sealant simultaneously on the first surface and the second surface of the spacer element, the fixture comprising:
an upper surface and a lower surface opposite to the upper surface, wherein the upper surface is coated with a hydrophobic material and the lower surface is flat and wherein the upper surface defines a cavity channel to receive and maintain the spacer element in a desired position for application of the primary sealant;

a secondary sealant; and
a dispenser for applying the secondary sealant in a clearance between the primary glazing unit and the secondary glazing unit, the dispenser comprising:
a hollow tubular member having a proximal end and a distal end opposite the proximal end, the proximal end defining a first hole and an attachment member and the distal end defining a second hole and a pair of wings, wherein the attachment member is configured to attach to a nozzle of the sealant containing cartridge and wherein the first hole receives the secondary sealant and the second hole dispenses the secondary sealant to adjoin the primary and the secondary glazing unit, and the pair of wings finishes and smoothens the secondary sealant in the clearance between the primary glazing unit and the secondary glazing unit.

2. The installation system as claimed in claim 1 , wherein the hydrophobic material includes one of silicon oil, grease, wax or machine oil.

3. The installation system as claimed in claim 1 , wherein the cavity channel of the fixture has a depth not greater than the width of the spacer element.

4. The installation system as claimed in claim 1 , wherein the hollow tubular member of the dispenser defines an internal passageway which is in a fluid communication with the first hole and the second hole.

5. The installation system as claimed in claim 1 , wherein the hollow tubular member of the dispenser gradually tapers from a relatively large volume at the proximal end to a small volume at the distal end.

6. The installation system as claimed in claim 1 , wherein the hollow tubular member of the dispenser has a defined length with a cross-section that increases in cross-sectional area going away from the proximal end to the distal end.

7. The installation system as claimed in claim 6 , wherein the cross-section of the hollow tubular member of the dispenser varies from a circular cross-section at the proximal end to a rectangular cross-section at the distal end 6 .

8. The installation system as claimed in claim 1 , wherein the attachment member of the dispenser at the proximal end can be threaded or snap fit.

9. The installation system as claimed in claim 1 , wherein the attachment member of the dispenser is configured to mate with the nozzle of the sealant containing cartridge.

10. The installation system as claimed in claim 1 , wherein the distal end of the dispenser is nonplanar with the proximal end 304 and are configured to be at an angle 10° to 50° from the proximal end.

11. The installation system as claimed in claim 1 , wherein each of the pair of wings at the distal end of the dispenser extend laterally from the second hole.

12. The installation system as claimed in claim 1 , wherein the second hole of the dispenser is defined by a pair of parallel long edges and a pair of parallel short edges.

13. The installation system as claimed in claim 1 , wherein the pair of wings of the dispenser are disposed in a plane parallel to the pair of short edges.

14. The installation system as claimed in claim 1 , optionally comprises a tool for supplying the secondary sealant to the first hole of the dispenser.

15. The installation system as claimed in claim 1 , wherein the spacer element is made of one of an aluminum or a poly-carbonate based material.

16. The installation system as claimed in claim 15 , wherein the tool is an electrically pressurized tool or a pneumatically pressurized tool.

17. The installation system as claimed in claim 1 , wherein the spacer element optionally consists of a moisture barrier disposed thereon and a hygroscopic material contained therein.

18. The installation system as claimed in claim 17 , wherein the moisture barrier is an aluminum foil.

19. The installation system as claimed in claim 1 , wherein the primary sealant includes one of an acrylic foam, a butyl coated poly-vinyl chloride or a poly-isobutyl.

20. The installation system as claimed in claim 1 , wherein the secondary sealant includes a silicon based material.

21. The installation system as claimed in claim 1 , wherein the multiple glazing unit exhibits improved acoustic property.

22. A method to fabricate multiple glazing units at the installation site, the method comprising:
providing at least a primary glazing unit, at least a secondary glazing unit, and a spacer element, wherein the spacer element has a first surface and a second surface opposite to the first surface;
applying a primary sealant simultaneously on the first surface and the second surface of the spacer element using a fixture;
attaching the first surface of the spacer element to the primary glazing unit;
attaching the second surface of the spacer element to the secondary glazing unit;
aligning the primary glazing unit in a substantially parallel relationship to the secondary glazing unit with the spacer element disposed there between at the periphery of the primary and the secondary glazing units; and
filling a secondary sealant in a clearance between the primary glazing unit and the secondary glazing unit to adjoin the secondary glazing unit and the primary glazing unit using a dispenser.
