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 intended 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 two longitudinally extending sealing members that are integrally associated with an essentially planar base section, each of said sealing member comprising a curved wall portion defining a hollow cross-section, and having mutually similar shapes and dimensions, said sealing members being symmetrically dis- posed, in relation to a symmetry axis perpendicular to said planar base section, over the base section.
  • 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 "P" is presently used as draught or wind excluders for win- dows and doors.
  • the straight portion of the P profile serves to anchor the sealing strip to the wing or the frame, while the curved portion provides the main part of the actual sealing.
  • the problem to be solved by the present invention is to provide such an elongate elastomeric sealing strip.
  • 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 two longitudinally extending sealing members that are integrally associated with an es- sentially planar base section, each of said sealing member comprising a curved wall portion defining a hollow cross-section, and having mutually similar shapes and dimensions, said sealing members being symmetrically disposed, in relation to a symmetry axis perpendicular to said planar base section, over the base section, where the two curved wall portions are unified between the hollow cross-sections into a single common wall portion.
  • each of the sealing members comprises an integrally associated flange that is thinner than said wall portions, which flanges protrude outwards from each respective curved wall portion at an angle that diverges upwards from said symmetry axis; and said flanges extend, when the sealing strip is in an unladened state, beyond an upper tangential line to the sealing members, which upper tangential line is parallel to said planar base section.
  • the wall thickness of the flanges decreases in the protruding direction.
  • 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 sealing strip is made of EPDM.
  • the inventive sealing strip is preferably made of cellular rubber, such as expanded, foamed, or sponge rubber, preferably expanded rubber as the closed cellular 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.
  • each sealing member has a vertical dimension of from about 2 to 15 mm, preferably from about 2 to 8 mm, in particular from about 3 to 8 mm.
  • the wall thickness of the sealing members 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 2 to 25 mm, preferably from about 5 to 15 mm, in particular from about 8 to 10 mm.
  • the flanges may protrude outwards from each respective sealing member at an angle of from about 0 to 90 degrees, preferably from about 30 to 60 degrees, in relation to the bottom surface.
  • the sealing strip according to the present invention provides numerous advantages, in particular regarding sealing properties, but also regarding the produc- tion of the sealing strip.
  • the flanges 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. In addition, the relative small wall thickness of the flanges provides 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 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 vul- canizer. 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 invention 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;
  • FIGS. 3a to 3c illustrates how a sealing strip according to the invention could be adapted to be applied to a corner of a door or window frame
  • FIG. 4 shows an inventive sealing strip thus adapted when applied to a window frame.
  • sealing strip 10 has a base 25 that extends the full length of the sealing strip.
  • the width of base 25 is adapted to receive separately pro- vided adhesive strips for bonding sealing strip 10 to the first 80 of two confronting surfaces.
  • base 25 can be provided with means to be received within a mounting track of one of the confronting surfaces.
  • Sealing strip 10 has two deforming sealing member, designated generally as 15 and 20, which protrude outwardly from base 25 for sealing contact with the second of the confronting surfaces (90 in FIG. 2).
  • Sealing members 15 and 20 include walls 30 and 35. which are integrally formed with base 25, which walls define confined spaces 40 and 45. The walls 30 and 35 are unified between the confined spaces 40 and 45 into a common wall portion 60.
  • flanges 70 and 75 protrude outwards from sealing member 15 and 20, and extends along the entire length of the sealing strip 10. Flanges 70 and 75 protrude along lines between a symmetry axis 50 and the horizontal plane coinciding with base 25. As seen in Fig 1, flanges 70 and 75 protrude, when the sealing strip is in an unladened state, above the upper tangential line of sealing members 15 and 20.
  • flange 70 is deformed inwardly toward the first 80 of the confronting surfaces when the second confronting surface 90 is brought into contact with and pressed against sealing strip 10.
  • an air duct 100 is defined between flanges 70, 75 and the second confronting surface 80.
  • the air duct 100 provides thermal insulation in addition to that provided by the confined spaces 40 and 45, resulting in overall excellent sealing and insulation properties.
  • Fig. 3a to 3c shows how a sealing strip 10 according to the invention can be adapted to be applied to a corner of a door or window frame.
  • Fig. 3a shows the sealing strip 10 from above, i.e. looking at the tops of the sealing members 15 and 20.
  • a section has been cut out in one 20 of the sealing members, leaving a cut out section 110 in this sealing member.
  • the cut out section 110 goes right through the sealing member 20 and the base of the sealing strip.
  • the cut out section 110 defines an isosceles right triangle with the right angle vertex 120 falling into, or contiguously to, the common wall portion 60.
  • Fig. 3b the sealing strip 10 is been bent around the vertex 120, so as to eventually bringing the cut surfaces of section 110 into contiguous contact.
  • Fig. 3c the cut surfaces of section 110 are brought into contact with each other, thus essentially restoring the confined space within sealing member 20. Sealing member 15 is still in its original closed state.
  • Fig. 4 the sealing strip 10 adapted as illustrated in Figs. 3a-c is shown when finally applied in a window frame 130. Both air ducts, as confined within the sealing members 15 and 20, are present even in the corner 140 of the window frame.
