Abstract

The assembly comprises a first fixed frame (1) and a second, movable frame (4) respective spaced strips of heat-swellable material (9, 10) are mounted at the facing end faces (7, 8) of the frames such that the material swells to fill the gap (15) when heated. <IMAGE>

Description

SPECIFICATION Fire protection door or window assembly The present invention relates to a fire protection door or window assembly.
A fire-resistant door construction, in which a material swelling up under the influence of heat is provided inter alia in the peripheral region of the narrow sides of a door wing and door mount, is described in DE-OS 29 42 559. This construction relates to the particular problem of the combination of a fire-resistant door construction with a door mount. The swellable material, for example the material known undertheTrade Mark"Palusol", is disposed in part in the end regions of the side faces and in part at the end faces of the door.
In addition, a one to two millimetres thick layer of a combustible material, for example rubber or expanded polyethylene, is provided on the upper side of the swellable material to accelerate swellingup of the material. It can, however, be counterproductive to equip a fire protection door with a material known to be combustible.
There remains a need for a fire protection door or window assembly in which, in simple manner and without unduly thick swellable material or use of a combustible material, the heat resulting from a fire will ensure sufficient sealing of a gap to be filled by the swellable material.
According to the present invention there is provided a fire protection door or window assemby comprising a first frame fixable to a structure and a second frame movable to the first frame into and out of a closed position in which it adjoins the first frame and in which at least one edge face of the first frame faces a respective edge face of the second frame and is disposed at a spacing therefrom, a respective mass of heat-swellable material being provided on each of said at least one edge face of the first frame and respective edge face of the second frame and the two masses being arranged at such a spacing from each other in the closed position of the second frame and so dimensioned that the gap between the spaced masses is fillable by the material when swollen through heating.
Preferably, each of the edge faces is provided with openings, for example slots. This offers the advantage of a substantial reduction in the passage of heat after the swelling-up of the swellable material.
An embodiment of the present invention will now be more particularly described by way of example with reference to the accompanying drawings, in which: Fig. 1 is a front elevation of a door embodying the invention; and Fig. 2 is a cross-section, to a scale enlarged compared with Fig. 1, along the line Il-Il in Fig. 1.
Referring now to the drawings there is shown a glazed door assembly comprising two wings or glazed frames 2 and 3 mounted within a frame 1 fixed to a building structure. As Fig. 2 shows in detail, swellable material is provided between door frame members 4 and the fixed frame 1 and optionally also between mutually oppositely disposed door frame members 4' abutting each other.
The door wing 3 is articulatedly connected at 5 with the fixed frame 1 and can thus be pivoted in direction of the double arrow 6. Fig. 2 shows the closed position.
A respective swellable material part 9 and 10 is fastened at each of the mutually oppositely disposed surfaces 7 and 8 of the movable frame member 4 and assqciated member of the fixed frame 1. The parts 9 and 10 are preferably in the form of elongate strips extending over the length of the end faces 7 and 8. The swellable material is fastened, preferably glued, on the end faces 7 and 8 and preferably comprises a vermicular graphite as effective substance with a special binding agent system. Such a swellable material is known in the trade under the Trade Mark "Intumex L". The swellable material is so dimensioned that, under the influence of heat, it fills out a gap 15 of the width a between the strips 9 and 10 and thereby prevents the passage of smoke and flame.
The same arrangement can be provided between both the afore-mentioned frame members 4', i.e. in the region 11 in Fig. 2. In that case, however, the swellable material must be recessed at the place for the passage of a locking bar 12.
Openings 13 and 14, such as slots, can be provided in a row one above the other in each of the end faces 7 and 8 and separated by webs of the material of the respective frame members.
An assembly embodying the invention as hereinbefore described takes account of the fact that the swellable material cannot just be made correspondingly thicker in order to be able to fill a gap of certain width, especially a width which for constructional reasons has to be present between door or window on the one hand and a frame fixed to a building on the other hand, since material of increased thickness may not swell sufficiently to fill the gap. By contrast, separation of the swellable material into two parts entails a relatively greater degree of swelling (referred to the original, unswollen mass) of the material. The two swellable material parts swell into the gap and can meet in about the middle.
1. A fire protection door or window assembly comprising a first frame fixable to a structure and a second frame movable relative to the first frame into and out of a closed position in which it adjoins the first frame and in which at least one edge face of the first frame faces a respective edge face of the second frame and is disposed at a spacing therefrom, a respective mass of heat-swellable material being provided on each of said at least one edge face of the first frame and respective edge face of the second frame and the two masses being arranged at such a spacing from each other in the closed position of the second frame and so dimensioned that the gap between the spaced masses is fillable by the material when swollen through heating.
2. An assembly as claimed in claim 1, wherein the
