Elongated profile provided with at least one insertion space

Abstract: The invention provides a universally applicable profile (2), provided with at least one insertion space (19a,19b) for fitting a sealing element, intended to be mounted on the closing side of a building element which co-operates, with a second building element, for example a panel, movable at least with respect to this profile. This profile (2) is made up of an elongated web (4) on either side of which is a chamber (19a,19b) defined by upright ribs (8a,16a,18b,16b) perpendicular to the web (4). The end walls of each chamber continue on into edges (18a,12a,18b,12b) terminating at a distance from and directed toward each other, while further there are supporting ribs (14a,6a,6b,14b), perpendicular to the web, directed away from the chambers and supporting the profile. This profile can be fastened to the building element by means of suitable fasteners.

Description: The invention relates to a sealing assembly according to the preamble of claim 1 and known from NL-A-7608393, Fig. 2. This known sealing assembly comprises two chambers, of which each chamber accommodates one end of a single, flexible, arch-shaped sealing element and is intended to be used in combination with swinging doors. The possibilities of use thereof are restricted. In practice there is a need for a universal sealing assembly which can be used for a variety of purposes, which also can accommodate different sealing elements and provides an excellent sealing. Up till now it has been necessary to design for each particular application a separate profile which is, of course, not very cost-effective. The invention aims to provide such an assembly and according to the invention this is achieved by the measure as described in the characterizing clause of claim 1. With only one standard profile a variety of sealing elements can be accommodated; the combination of two elements within one profile results into a more effective sealing. Preferred embodiments of the assembly are described in the subclaims. It is observed that US-A-3 141 204 describes a sealing assembly to be used in a door frame construction, particularly for accommodation a swinging door, comprising an elongate outer box-like first chamber which constitutes the door frame with therein a second, smaller chamber which slidingly accommodates in its open front edge a spring-biased pressure plate movable to, and away from the door edge. The central part of this pressure plate is provided with two longitudinal cut-outs at a distance of each other, each defining a chamber which accommodates one end edge of a single flexible arch-shaped sealing element of which the outer surface sealingly co-operates with the door edge. At both upright edges of the pressure plate the end edges of the outer- and inner box structure define a chamber and each chamber accommodates a flexible sealing element which co-operates with an end edge of the pressure plate. The invention is elucidated on the hand of the drawing, in which: Figure 1a is a cross-section of the basic profile according to the invention. Figure 1b is a cross-section of this profile in which the chambers have been provided with a seal in the form of a brush. Figure 1c is a cross-section of an embodiment as shown in 1b, in which a strip of foam producing fire-resistant material is fitted in each of the chambers. Figure 1d is a cross-section as shown in figure 1c combined with a strip of foam-producing material in the space between the two chambers. Figure 1e is a cross-section similar to figure 1d, provided with a second strip of foam-producing material. Figure 2 shows a cross-section of the embodiment as shown in figure 1c fitted in a recess in a building component. Figure 3 shows a cross-section of the embodiment as shown in figure 1c in which the profiles are mounted on the butt ends of a building component. Figure 4 shows an embodiment similar to figure 3 in which the profiles are combined with extra protective profiles. Figure 5 shows an embodiment as shown in figure 4 in which the main body of the protective profiles is interrupted. Figure 6 shows an embodiment in which each of the profiles according to the invention is incorporated in a profile for a swing door. Figure 7 shows an embodiment as shown in figure 6 in which an extra insertion space for foam-producing material has been made in each building component. Figure 8 shows an embodiment in which a profile as shown in figure 1d is incorporated in a recess in an building element and co-operates with the butt end of a panel which is moveable with respect to the recess. Figure 9 shows an embodiment similar to figure 8 in which the butt end of the panel is finished in a curved form. Figure 10 shows an embodiment in which a profile according to the invention is mounted on a frame part. Corresponding parts in the figures are indicated by the same reference numbers and will not be further elucidated. The basic form of the profile according to the invention is shown in the cross-section in figure 1a; in the figure the profile is indicated in its entirety by reference numeral 2. The profile is manufactured in great lengths by extrusion and its length dimension is thus perpendicular to the plane of the drawing. The profile 2 consists of a web 4 on either side of which are the upright ribs 6a and 6b respectively; the cross ribs 10a and 10b respectively emanate from ribs 6a and 6b while the ribs 8a and 8b terminate in the end edges 12a and 12b diagonal to them. Diagonal to ribs 10a and 10b are ribs 14a and 14b and in their continuation ribs 16a and 16b. Ribs 16a and 16b terminate in the end edges 18a and 18b diagonal to them, which, while leaving an intermediate space 19a and 19b respectively, align with ribs 12a and 12b. Ribs 6a, 6b, 14a and 14b bear on surface 20 of the schematically indicated building element 22 to which the profile is fastened by means of fasteners - not shown - such as screws. As shown in the drawing ribs 16a, 8a and the end edges 18a, 12a define a chamber 24, while ribs 16b, 8b and the end edges 12b and 18b define a second chamber 26; furthermore, ribs 6a, 6b, web 4 and surface 20 of the building element 22 define a chamber 28. Finally, there is an open chamber 40, facing the exterior, which is bounded by the external wall of web 4 and the external walls of ribs 8a and 8b. As will be clear from the following, this profile proposed according to the invention offers an up to now unprecedented multitude of possible applications. Figure 1b shows a situation in which brush strips 30 and 32 respectively are present in chambers 24 and 26 respectively. In combination with an adjacent surface, not shown in these figures, these provide for a seal against smoke and draught. Figure 1c shows how strips 34 and 36 respectively, known in themselves, which produce foam on being heated are incorporated in chambers 24 and 26 respectively, supplementing the brush strips 30 and 32 respectively. Figure 1d shows how in addition to the embodiment in figure 1c a foam-producing strip 38 is present in chamber 28. Finally, figure 1e shows how in addition to the embodiment in figure 1d a foam producing strip 40a - when heated - is placed in the open chamber 40 on the front side. Figure 2 shows an embodiment with two profiles 2a and 2b respectively placed opposite each other and made-up as shown in figure 1c (and therefore not further explained), inserted here in recesses 42 and 44 respectively which are formed in the butt ends 46 and 48 respectively of two panels 50 and 52 respectively; one of the panels may be moveable with respect to the other, whereby both panels may be moveable, or one panel may be fixed and the other moveable. The profiles 2a and 2b respectively can be fastened in any suitable manner to the panels 50 and 52 respectively by, for example, screws which are not shown on the drawing. Figure 3 shows an embodiment in which the profiles 2a and 2b respectively, having the configuration as shown in figure 1c, are fastened by means of fasteners not shown in the drawing, for example, screws, to the flat butt ends 54 and 56 respectively of the panels 58 and 60 respectively. Figure 4 shows the cross-section of an embodiment in which the profiles 2a and 2b respectively, having the configuration as shown in figure 1c, are inserted in two auxiliary profiles 62a and 62b, each having a main body 64a and 64b, which continues into the upright edges 66a, 66b, 66c and 66d respectively closing about profiles 2a and 2b respectively; the edges continue further forming the terminal edges 70a, 70b and 70c, 70d respectively which close about the panels 68a and 68b. With these auxiliary profiles 62a and 62b, excellent protection of the panels 2a and 2b is realized. Figure 5 shows a cross-section similar to figure 4 in which identical parts are indicated by the same reference numbers; the difference with the embodiment as shown in figure 4 lies in the fact that the main bodies 64a and 64b of the auxiliary profiles 62a and 62b are interrupted resulting in a break 72a and 72b respectively running in a longitudinal direction; furthermore, at that spot an elongated chamber 74a and 74b respectively is formed in the building elements 68a and 68b and a strip 76a and 76b respectively which produces foam on being heated is placed in chamber 28 in the way as shown in figure 1d. In this way a dual goal is achieved: in the first place, the auxiliary profiles 62a and 62b are now split into two parts which are thermally isolated with respect to each other and, moreover, in the event of a fire the chambers 74a and 74b and the spaces 72a and 72b between the main bodies of the auxiliary profiles will entirely be filled with fire-resisting foam. Figure 6 shows an example of an embodiment in which the profiles 2a and 2b respectively, having the configuration as shown in figure 1c, are incorporated in a profile of the kind as used for swing doors; both swing door profiles 80a and 80b respectively consist each of a main body 84a and 84b respectively to be fastened to the butt end 82a and 82b respectively of two swing doors and which, perpendicular to it, has a cover strip 86a and 86b respectively reaching to the other panel. Figure 7 shows a cross-section of an embodiment which basically corresponds with the one shown in figure 6 and in which identical parts are indicated by corresponding reference numerals; the difference with the embodiment as shown in figure 6 is that the main bodies 84a and 84b, in the manner already explained with regard to figure 5, are interrupted by a break 88a and 88b respectively and that at that place, as in the embodiment mentioned above, elongated chambers 92a and 92b are formed in the panels 90a and 90b. As in the embodiment which has already been discussed, fire-resisting strips 94a and 94b which produce foam are placed at the spot where these breaks are located. Because of this, as in the embodiment shown in figure 5, a thermal break is created which in combination with the foam barrier from the foam strips 94a and 94b offers excellent protection in the event of a fire. Figure 8 shows an embodiment of a combination of a profile 100 of the type as shown in the cross-section in figure 1c, now inserted in a recess 102 of a fixed building component 104 and co-operating with the butt end 106 of an opposite panel 108. Figure 9 shows a similar situation, but here profile 100, inserted in recess 102 of building component 104, co-operates with the rounded butt end 106 of a swing door 108. Finally, figure 10 shows how a profile 110, having the configuration as shown in figure 1c - and therefore not elucidated further - is incorporated in a frame corner 112 and co-operates with the strike surface 114 of a door 116. From the foregoing it is evident that the application possibilities of the profile according to the invention are practically unlimited. In addition, it should be noted that the profile has extremely favourable fire-resisting properties, especially when strips which produce foam on being heated are fitted in its chambers. Tests have shown that when there is an increase in temperature to approximately 120 °C the brushes will have already been consumed, but at that temperature, a vigorous foaming develops; the created foam forms a very effective barrier to fire and prevents effectively for a long time fire from breaking through.
