Abstract
A pile weatherstrip has a pile of yarn ultrasonically welded to a backing strip inside a channel defined by flanges, called pile directors, which direct the pile perpendicularly with respect to the backing. A film provides a covering for the pile and is releasably attached to the flanges on the outside thereof. The covering film may have perforations therein which are located adjacent to the flanges near the upper ends of the flanges. Alternatively, a weak ultrasonic weld of the covering to the flanges, such as made at much lower energy than used to weld the pile and the backing together, provides a releasable attachment for the covering. The covering protects the pile, for example during installation in a frame which may be painted after the weatherstrip is installed. The covering can be released by being pulled off the pile director flanges after installation and painting.
Description
WEATHERSTRIP WITH RELEASABLE PROTECTIVE COVERING
Description The present invention relates to weatherstripping and improves such weatherstripping by facilitating protection of the sealing member thereof during installation, especially when the frame of the fenestration product (window, door, etc.) in which the weatherstrip is installed is painted in the area of the weatherstripping.
The invention is especially adapted for protection of the pile providing the sealing member of weatherstrip in which the pile is attached to a backing strip having a channel on the inside of flanges constituting walls of the channel; such flanges sometimes being called pile directors. Such weatherstrips are described in the following patents: Horton, U.S. Patent Nos. 3,175,256 and 4,148,953 and Johnson, U.S. Patent Nos.
5,338,382, 5,807,451, and 5,817,390.
In accordance with the invention, the weatherstrips have a thin flexible film covering the pile wherein the film is releasably attached to the outside of the pile directors. The releasable attachment may be via perforations in and along the film immediately above the upper ends of the pile directors, or with weak, ultrasonic welds which are made with much lower energy (and heating) than the welds attaching the pile to the backing. When installed as in a T-Slot of a frame, the covering of the pile provided by the film is readily released and removed after installation or painting.
Protective covering or masks, such as of adhesively backed material have been used to protect carpets, thresholds, floorboards, gaskets and the like, especially during painting operations. See Elliott, U.S. Patent No. 6,210,466, 4/01; Headrick et al., 5,611,173, 3/97; Nauman, 5,489,459, 2/96; Cox et al., 5,421,936, 6/95;

In accordance with the presently preferred embodiment of the invention, a pile weatherstrip has a pile of yarn ultrasonically welded to a backing strip inside a channel defined by flanges, called pile directors, which direct the pile perpendicularly with respect to the backing. A film covers the pile and is releasably attached to the flanges on the outside thereof. The film attachment may have perforations located along the outsides of the flanges adjacent the upper edges thereof. Alternatively, the film may be attached to the flanges by a weak ultrasonic weld made at much lower energy than used to weld the pile and the backing together. The cover protects the pile, for example during installation in a frame which may be painted after the weatherstrip is installed, and the cover can be released or removed by being pulled off the pile directors after installation and painting.
The foregoing and other features and advantages of the invention will become more apparent from the following description and drawings, in which:
FIG. 1 is a perspective view showing an improved weatherstrip provided by the invention installed in a frame of a window or door;
FIG. 2 is a perspective view illustrating two embodiments of the weatherstrip provided by the invention; and FIG. 3 is a perspective view illustrating the covering of a weatherstrip provided by the invention in the process of being released from the weatherstrip.
The drawings show a pile weatherseal which may be made in accordance with the above referenced Horton and Johnson patents with a protective covering 12 over the pile 16. The weatherseal is referred to as an ULTRA MASKTM weatherseal. The covering 12, as shown in FIG. 3, is a film or sheet of thin plastic material, similar to that used in providing fins inside or outside the pile in the above referenced Horton or Johnson patents, is ultrasonically welded to the outside of the pile directors (flanges) 14. The film -is looped over and covers the pile 16 to provide the releasable covering on cladding 12.
After the covering or cladding 12 is looped around the pile sealing member 16 and ultrasonically welded to the outsides of the pile directors 14 around the pile sealing member 16, it can be perforated to provide lines of spaced perforations 18 in the area of pile directors just above the upper edges of pile directors 14 (see FIG. 2).
The completed weatherstrip with its releasable covering 12 may be wound on a packing reel for storage or shipment.
Alternatively to the use of the perforations 18, a low energy weld 20 of the film to the outsides of the pile directors 14 may be provided to make the releasable attachment thereby eliminating the need for the perforation.
The weatherseal 10 may be installed in fenestration products (e.g., windows, doors, etc.) in a T-Slot 22 of frame 24, as shown in FIG. 1, by hand, or with an automated insertion device, or online in a vinyl profile extruder used to make the frame. The covering or cladding 12 protects the sealing member 16 during fabrication processes. A
primary application for the invention is to protect against is what is the latest trend in vinyl windows which to paint the profiles on certain surfaces to provide the consumer with more color options at a cost effective price. This process is lower cost compared to use of colored vinyl material itself.
Painting of fenestration products wherein pile weatherstripping was installed required the installer to mask off the weatherstripping with special tape before painting.
This was very labor intensive and time consuming. Sometimes the fabricator just sprayed paint over the weatherstripping which filled the pile with paint thereby losing its sealing properties.
Another problem fabricators faced is that the high air pressure used to propel the paint particles onto the surface of the fenestration product can actually loosen fibers in the pile and create a situation in which the fibers contaminate the painted surface. These problems in prior, conventional installations and painting are solved by this invention.
The covering 12 such as solid, felted or spun polyolefin, like polypropylene, may be, as discussed above, for example, a film or sheet of plastic which may be 6 mil thick, perforated just above the pile directors 14. A low energy weld 10 in the area of the pile director may be alternatively used. In either embodiment, covering 12 is easily removed as by being torn away, after being installed in a typical T-Slot retention groove 22, which is used in most vinyl or even aluminum extrusions.
The cladding or covering 12, is preferably ultrasonically welded, but could also be adhered by using conventional adhesives. More specifically, a polyolefin based sheet or film 12 ranging from .5 mil to 10 mil in thickness may be used for the covering, but other types of plastic or textile film could be used. Color of the film 12 is not critical to the actual manufacturing process, but a clear covering may be preferred by the end user so that the color of the underlying sealing members can be seen after installation.
In accordance with the presently preferred embodiment of the invention, a pile weatherstrip has a pile of yarn ultrasonically welded to a backing strip inside a channel defined by flanges, called pile directors, which direct the pile perpendicularly with respect to the backing. A film covers the pile and is releasably attached to the flanges on the outside thereof. The film attachment may have perforations located along the outsides of the flanges adjacent the upper edges thereof. Alternatively, the film may be attached to the flanges by a weak ultrasonic weld made at much lower energy than used to weld the pile and the backing together. The cover protects the pile, for example during installation in a frame which may be painted after the weatherstrip is installed, and the cover can be released or removed by being pulled off the pile directors after installation and painting.
The foregoing and other features and advantages of the invention will become more apparent from the following description and drawings, in which:
FIG. 1 is a perspective view showing an improved weatherstrip provided by the invention installed in a frame of a window or door;
FIG. 2 is a perspective view illustrating two embodiments of the weatherstrip provided by the invention; and FIG. 3 is a perspective view illustrating the covering of a weatherstrip provided by the invention in the process of being released from the weatherstrip.
The drawings show a pile weatherseal which may be made in accordance with the above referenced Horton and Johnson patents with a protective covering 12 over the pile 16.

The covering 12, as shown in FIG. 3, is a film or sheet of thin plastic material, similar to that used in providing fins inside or outside the pile in the above referenced Horton or Johnson patents, is ultrasonically welded to the outside of the pile directors (flanges) 14. The film -is looped over and covers the pile 16 to provide the releasable covering on cladding 12.
After the covering or cladding 12 is looped around the pile sealing member 16 and ultrasonically welded to the outsides of the pile directors 14 around the pile sealing member 16, it can be perforated to provide lines of spaced perforations 18 in the area of pile directors just above the upper edges of pile directors 14 (see FIG. 2).
The completed weatherstrip with its releasable covering 12 may be wound on a packing reel for storage or shipment.
Alternatively to the use of the perforations 18, a low energy weld 20 of the film to the outsides of the pile directors 14 may be provided to make the releasable attachment thereby eliminating the need for the perforation.
The weatherseal 10 may be installed in fenestration products (e.g., windows, doors, etc.) in a T-Slot 22 of frame 24, as shown in FIG. 1, by hand, or with an automated insertion device, or online in a vinyl profile extruder used to make the frame.
