Definitions

  • This invention relates to weather stripping that is particularly suited for sealing the spaces or joints that exist between doors, windows and other closures or the like and the frames or structural supports therefor.
  • Pile weather strip is well known and has been commercially available for many years. It consists of a backing to which is secured a pile strip of resilient fibers. Typical of a pile weather strip is that shown in U.S. Patent No. 3,175,256, issued March 30, 1965, R.C. Horton. The pile weather strip shown in that patent is sold under the trade mark Fin-Seal and is characterized by a barrier strip of impervious, flexible, sheet material fixed to the backing and located within the pile strip. In its more elementary form conventional pile weather strip omits the aforementioned barrier strip.
  • Pile weather strip commonly is supported in what is known as a T-slot.
  • the T-slot may be in the closure element, e.g., door or window, or in the frame or support therefore.
  • it is a T-shaped slot having a longitudinally extending groove (the crossbar of the T) and a longitudinally extending opening (the upright of the T) communicating with the groove and of lesser width than the width of the groove.
  • the pile weather strip is inserted into the T-slot from an open end thereof and is slid longitudinally into location in the T-slot.
  • this mode of installation does become more difficult as the length of the T-slot increases.
  • Pile weather strip does wear out, of course, and it may be necessary to replace it from time-to- time in the field. In the field it may not be possible to gain access to an open end of the T-slot, at least without substantial disassembly of the closure, frame or other support, which is time-consuming and costly. Therefore, what is required is some technique that will permit pile weather stripping to be readily retrofitted in the field when access to the open end of the T-slot is not possible or difficult.
  • a weatherstrip comprising a backing having a front surface, a bottom surface opposite to said front surface and first and second side edges, a resilient sealing body upstanding from said front surface, secured to said backing and extending longitudinally of said backing at a location spaced inwardly from said first and second side edges, whereby said backing on either side of said sealing body and between said first and second side edges constitutes flanges, said weatherstrip being adapted to be inserted into a T-slot comprising a longitudinally extending groove having a longitudinally extending opening of lesser width than the width of said groove which opening communicates with said groove when said weatherstrip is so inserted into said T-slot said backing being located in said groove and said sealing body protruding through said opening, the width of said backing between said side edges thereof being greater than the width of said opening, characterised by the provision in said backing of a line of weakness extending longitudinally of said backing at a location between said sealing body and one of said edges of said backing and thus in one of said said opening
  • the present invention also provides a method for inserting a weatherstrip of the type set out in the preceding paragraph into a T-slot of the type set out in the preceding paragraph which comprises inserting a first portion of said backing between said line of weakness and one side edge of said backing through said opening into said groove, pushing said weatherstrip towards said T-slot while bending a second portion of said backing between said line of weakness and the other edge of the backing to a sufficient extent to permit the remainder of said backing to pass through said opening into said groove, and permitting said second portion of said backing between said line of weakness and said other edge of said backing to spring into said groove after said second portion has passed through said opening.
  • the invention also resides in the combination of the aforesaid weatherstrip and T-slot, the weatherstrip being located in said T-slot with said backing in said groove and said sealing body extending through said opening.
  • a pile weather strip of the instant invention includes a backing 10 having a front surface 11, a bottom surface 12 opposite to the front surface and side edges 13 and 14. Also included is a pile strip 15 of resilient fibers upstanding from front surface 11.
  • the pile strip is secured to backing 10 in known manner, e.g., by being woven into the backing and/or adhered thereto and extends longitudinally of the backing at a location spaced inwardly from side edges 13 and 14.
  • Included within or immediately adjacent to pile strip 15 may be a barrier strip of the type disclosed in aforementioned U.S. Patent No. 3,175,256, but this is entirely optional.
  • the portions of backing 10 on either side of pile strip 15 and between side edges 13 and 14 constitute flanges 16 and 17 that are devoid of pile material.
  • T-slot 18 The weather strip is adapted to be inserted into a T-slot 18 formed in a window, door or other closure or in the frame or support therefor, this component being designated 19 and having an edge 20.
  • T-slot 18 includes a longitudinally extending groove 21 having a groove width A and a longitudinally extending opening 22 having a width B that is less than width A of groove 21. Opening 22 communicates with groove 21 and, in fact, extends between groove 21 and edge 20.
  • the weather strip and T-slot are so constructed and proportioned relative to each other that when the weather strip is inserted into the T-slot, backing 10 is located in groove 21, and pile strip 15 protrudes through opening 22 and beyond edge 20. Since the width of backing 10 is greater than that of opening 22, the weather strip necessarily is retained in the T-slot as a result of flanges 16 and 17 being located beneath flanges 23 and 24 of component 19.
  • Component 19 usually is fabricated of metal particularly aluminum, but it may be of plastics or any other suitable material depending on the nature of the application.
  • the weather strip itself may be made of known materials.
  • the pile strip 15 usually is made of filament polypropylene yarns that have been siliconed and ultraviolet stabilized, but other materials may be employed.
  • the fibers of the pile should be resilient and durable, however.
  • Backing 10 may be and preferably is of two part construction, the upper part 25 being a woven layer of, for example, polypropylene yarns, and the lower part 27 being a continuous layer of compatible plastics material, e.g., polypropylene extruded onto and laminated to the underside of woven layer 25.
  • Pile strip 15 may be woven into backing 10, and the extruded layer 27 of plastics material serves to assist in holding pile strip 15 in place.
  • a pile weather strip embodying the instant invention is capable of being installed in a T-slot in the normal way, i.e., by being slid longitudinally into the slot via an open end thereof.
  • the weather strip also is capable of being inserted into the T-slot by passage of backing 10 through opening 22 into groove 21.
  • a line of weakness 26 is provided in backing 10 extending longitudinally of the backing and at a location between pile strip 15 and one of the side edges, namely, in the embodiment shown, side edge 14.
  • the line of weakness 26 is provided in flange 17. Line of weakness 26 extends inwardly from bottom surface 12 toward front surface 11 but only part way through backing 10.
  • line of weakness 26 is a score line or a so-called "kiss cut". Also in a preferred embodiment its depth is only 15% to 30% of the depth of backing 10 and, in the case where the backing is composed of an upper woven layer 25 and a continuous lower layer 27 of plastics material, in which case both layers normally are of about equal depth, the depth of line of weakness 26 is only about 30% to 60% of the depth of layer 27. In a preferred embodiment of the invention line of weakness 26 is located inwardly from edge 14 at a point 60% to 80% of the width of flange 17.
  • a line of weakness 26 is provided in each flange 16 and 17 so that the weather strip is not handed but can be installed by inserting either flange into the T-slot.
  • flange 16 To insert the pile weather strip into the T-slot, flange 16 first is inserted through opening 22 into the part of groove 21 below flange 23. The remaining part of the weather strip then may be inserted into the T-slot by pushing the weather strip towards the T-slot and running one's finger or a tool along the upper surface of flange 17 opposite line of weakness 26 causing a hinging action of flange 17 about the line of weakness 26. This effectively reduces the width of backing 10 so that it can pass through opening 22. Once this has been accomplished, flange 17 will, as a result of what has been termed a "living hinge action", spring into the part of groove 21 beneath flange 24. Since line of weakness 26 resists any tendency for flange 17 to bend downwardly, the pile weather strip cannot be readily removed from the T-slot, although it can be removed forcefully when it is worn out or damaged.
  • pile weather strip embodying in the instant invention is particularly useful for retrofit, it also is useful in O.E.M. procedures where long lengths of weather strip have to be inserted in T-slots and frictional resistance may be met.
