Definitions

  • the present invention relates to sealing strips intended to be arranged on wings, i.e. swingable, slidable or otherwise movable members such as doors or windows, for closing an opening, or parts co-operating with such wings.
  • the sealing strips are primarily intend for the purpose of sealing or insulating against cold, heat, draught, wind, airborne pollutants, vermin, but may also be used for vibration dampening or sound insulation.
  • the sealing strips are primarily intend to be used in connection with wings in buildings, such as doors or windows, it may also be used in vehicles, machines, white goods, fan installations etc.
  • the present invention relates to an elongate elastomeric sealing strip comprising an essentially planar base section, the cross-section width of which has a first and a second edge, three longitudinally extending sealing members that are integrally associated with said planar base section, a first and a second of which are positioned at said first and second edge, respectively, and the third of which is positioned at a point located equidistantly between said first and second edges, the cross-section of the sealing strip being symmetric around a perpendicular crossing the width of said base section at said point located equidistantly between the said edges.
  • Sealing strips of this general kind are previously known to quite some extent in the art. For instance, sealing strips with cross-sections or profiles generally resembling to a capital "E" is presently used as draught or wind excluders for windows and doors.
  • the straight portion of the E profile serves to anchor the sealing strip to the wing or the frame, while the three solid flanges provide the main part of the actual sealing by defining two insulating air ducts when in contact with the con- fronting surface.
  • an elongate elastomeric sealing strip one general embodiment of which is defined by appended claim 1. More particularly, this general embodiment comprises an elongate elastomeric sealing strip comprising an essentially planar base section, the cross-section width of which has a first and a second edge, three longitudinally extending sealing members that are integrally associ- ated with said planar base section, a first and a second of which are positioned at said first and second edge, respectively, and the third of which is positioned at a point located equidistantly between said first and second edges, the cross-section of the sealing strip being symmetric around a perpendicular crossing the width of said base section at said point located equidistantly between the said edges, which third sealing member has a hollow cross-section profile and a wall portion defined by an external boundary and an internal boundary, said boundaries being essentially parallel in relation to each other.
  • the present sealing strip When in use, i.e. when compressed between confronting surfaces in the clearance between a door/window and the corresponding frame, the present sealing strip provides three insulating air ducts.
  • said third sealing member extends beyond an upper tangential line to the first and the second sealing members, which upper tangential line is parallel to said planar base section, when the sealing strip is in an unladened state.
  • the hollow cross-section profile of said third sealing member is essentially circular.
  • said first and second sealing members flush with said first and second edges, respectively.
  • the inventive sealing strip is preferably made of EPDM (Ethylene- Propylene-diene terpolymer), EPM (Ethylene-Propylene Copolymer), SBR (Styrene- Butadiene Rubber), PVC (Polyvinyl chloride), EVA (Ethylene Vinyl acetate Copolymer), or thermoplastic elastomer.
  • EPDM Ethylene- Propylene-diene terpolymer
  • EPM Ethylene-Propylene Copolymer
  • SBR Styrene- Butadiene Rubber
  • PVC Polyvinyl chloride
  • EVA Ethylene Vinyl acetate Copolymer
  • thermoplastic elastomer thermoplastic elastomer
  • the inventive sealing strip is preferably made of cellular rubber, such as expanded, foamed, or sponge rubber, preferably expanded rubber as the closed cel- lular structure of expanded rubber makes it impervious to water.
  • the inventive sealing strips may be provided with a self-adhesive layer for mounting. They may also be tacked or glued into place by means of separately provided adhesive. Alternatively, they may also be stapled or pinned to the substrate surface.
  • the annular sealing member has an essentially circular cross- section, having a diameter of from about 3 to 25 mm, preferably from about 3.5 to 12 mm, in particular from about 4 to 9 mm.
  • the wall thickness of the sealing member may be from about 1 to 4 mm, preferably from about 1 to 2 mm, in particular from about 1 to 1.5 mm.
  • the planar base section may have a width of from about 4 to 25 mm, preferably from about 5 to 15 mm, in particular from about 8 to 10 mm.
  • the sealing strip according to the present invention provides numerous advantages, in particular regarding sealing properties, but also regarding the production of the sealing strip.
  • the hollow sealing member provide for improved flexibility of the sealing strip in relation to unevenness in the confronting surfaces between which it is applied. This means that the sealing properties of the present sealing strip in relation to varying clearances between confronting surfaces is improved in relation to prior art sealing strips.
  • the relative small wall thickness of the hollow sealing member provide for even more improved flexibility of the sealing strip in relation to such unevenness.
  • the sealing strip of the invention provides better sealing characteristics at lower compressions than do the prior art sealing strips, which facilitates closing.
  • the sealing properties are particularly improved for situations where the system of the sealing strip and the confronting surfaces is subjected to wind or draught, especially in situations where the confronting surfaces are put in motion in relation to each other.
  • the present sealing strip leaves little or no opportunities for error in application (i.e. the sealing strip is more or less what is occasionally referred to as "foolproof), due to the symmetric design, as will be appreciated by the artisan.
  • the sealing strip may be manufactured by extruding a continuous length of elastomeric material from a conventional extruder, which includes a die formed in the shape of the cross-section of the sealing strip. Uncured polymer is fed into the extruder, which forces the material out from the extruder in the desired configuration. The uncured, extruded sealing strip is drawn through a vulcanizer in a conventional manner. The sealing strip will cure due to the temperature of the vulcanizer. As the sealing strip proceeds from the vulcanizer, it will be cut into desired lengths and then processed as appropriate for each application.
  • Multiple sealing strips may be extruded simultaneously and in parallel through one die; this is because the width of the cross-section of the present sealing strip is well defined, without any parts protruding in lateral direction.
  • FIG. 1 is side elevational view of one embodiment of the sealing strip of the inven- tion mounted on a first surface and prior to contacting a second confronting surface;
  • FIG. 2 is a view similar to FIG. 1 showing the operative position in which the second confronting surface has contacted the sealing strip;
  • sealing strip 10 has a base 22 that extends the full length of the sealing strip.
  • the width of base 20 is adapted to receive separately provided adhesive strips for bonding sealing strip 10 to the first 130 of two confronting surfaces.
  • base 20 can be provided with means to be received within a mounting track of one of the confronting surfaces.
  • Sealing strip 10 has three sealing members, designated generally as 50, 60, and 70, which protrude outwardly from base 20 for sealing contact with the sec- ond of the confronting surfaces (140 in FIG. 2).
  • the central sealing member 70 include a wall 100, which is integrally formed with base 20, which wall defines a confined space 90.
  • hollow sealing member 70 protrudes, when the sealing strip is in an unladened state, above the upper tangential line of sealing members 50 and 60.
  • hollow sealing member 70 is deformed inwardly to- ward the first 130 of the confronting surfaces when the second confronting surface 140 is brought into contact with and pressed against sealing strip 10.
  • air ducts 150 and 160 are defined between sealing members 50, 60, and 70, and the second confronting surface 140. Air ducts 150 and 160 provide thermal insulation in addition to that provided by the confined space 90, resulting in overall excellent sealing and insulation properties.
