Description

SPECIFICATION Seals for doors, windows and the like The present invention relates to seals for doors, windows and the like.
The invention aims at providing a seal for a door, window or the like, which seal would function both to provide draught sealing under ordinary conditions and, when subjected to elevated temperature, as under fire conditions, would function to provide sealing against hot smoke and hot combustion gases and also would protect the draught-sealing function against damage by elevated temperature.
In accordance with the present invention, there is provided a seal for a door, window or the like, comprising an elongate holder having a first longitudinal channel containing intumescent material and a second longitudinal channel retaining or adapted to assist in retaining a draught-sealing member, the intumescent material in the first channel intumescing from the channel through an opening thereof when subjected to elevated temperature, as under fire conditions, to provide sealing against hot smoke and hot combustion gases, the draught-sealing member protruding from the holder and having a resilient part external to the holder for providing draught-sealing, the opening of the first channel being positioned relative to the resilient external part of the draught-sealing member, such that in the event of a fire on the same side of the draughtsealing member as the intumescent material, the material which intumesces from the first channel protects the part of the draught-sealing member external to the holder from the direct heat of the fire.
It will be understood that the seal of the invention, in providing draught-sealing also provides sealing against smoke and fumes of a temperature insufficiently high to cause the intumescent material to intumesce.
The resilient external part of the draughtsealing member may be tubular or may be in the form of a blade.
Preferably the opening of the first channel is directed towards the resilient external part of the draught-sealing member, which thereby acts as a guard or shield to protect the intumescent material against tampering.
Alternatively the opening of the first channel may be directed substantially parallel to the direction in which the draught-sealing member protrudes from the holder.
In one aspect of the invention, the seal may be designed as a stop seal, i.e. for attachment to a stop of a door frame.
In another aspect of the invention, the seal may be designed as a threshold seal for attachment to a door, the resilient part of the draught-sealing member also acting to provide sealing against penetration of water and moisture, e.g. rainwater, beneath the door.
In a further aspect of the invention, the seal may be designed for use either as a stop seal or a threshold seal according to choice.
The invention is further described below by way of example with reference to the accompanying drawings, wherein: Figure 1 A is a transverse section of a stop seal according to the invention; Figure 1 B is a horizontal section through part of a door and a door frame fitted with the stop seal of Figure 1 A; Figure 2 is a vertical section through part of a door fitted with a threshold seal according to the invention and the threshold of the door, the threshold seal being shown in transverse section; and Figure 3 is a vertical section through part of a door fitted with a further seal according to the invention, the seal being in this case used as a threshold seal, and the threshold of the door, the seal being shown in transverse section.
In the drawings, like reference numerals indicate like parts.
Referring to Figure 1 A, a stop seal 1 comprises a rigid elongate holder 2 of uniform section. The holder 2 defines a first longitudinal channel 3 having an opening 4 and a second longitudinal channel 5 having an opening 6. The first longitudinal channel 3 is filled with a solid coherent mass of intumescent material 7. The second longitudinal channel 5 holds a draughtsealing member 8 made of resilient material. A bead part 9 of the member 8 is retained in the channel 5, an intermediate web part 10 of the resilient member 8 extends through the opening 6 of the channel 5 and a tubular part 11 of the resilient member is external to the holder 2 and covers the opening 4 of the first channel 3. The ends of the tubular part 11 are preferably sealed off for the reason given below.
The holder 2 comprises a flange 12 for use in attaching the seal 1 to a stop 13 of a door frame 14, as shown in Figure 1 B.
The flange 12 may be fastened to the stop by nails or screws (not shown). A door 14 is hingedly mounted in the door frame, the direction of opening movement of the door being indicated by arrow A. When the door 15 is closed it abuts against the stop 13 and the tubular part 1 1 of the draught-sealing member engages one face of the door (and is partly deformed by the door) thereby providing draught-sealing between the door and the door-frame. As mentioned above, by draughtsealing, we mean sealing not only against draughts, but also against smoke and fumes of a temperature insufficiently high to cause the intumescent material to intumesce.
A baffle 20 may be provided within the channel 3, adjacent the opening 4 of the channel, for a purpose referred to below.
The tubular part 11 of the member 8, since it covers the opening 4 of the channel 3, acts as a shield or guard for the intumescent material 7. The tubular part 1 1 shields the opening 4 from view and physically prevents or at least makes difficult the insertion of a probe through the opening 4 into the intumescent material. Thus the tubular part 1 1, acting as a shield or guard, inhibits a mischievous or malicious person, tempering with the seal, from inserting a probe through the opening 4 and thereby effecting loosening or removal of at least some of the intumescent material 7. Further tamper-proofing is provided by the baffle 20 (if present) as described in our British patent no. 1529733.
In the event of a fire when the holder and the intumescent material intumesces, that is it expands through the opening 4 of the first channel 3 forming a voluminous heat-resistant coherent mass 16, indicated by dashed lines in Figure 1 B, which seals any gap between the door 15 and the door frame 14 (even if the part 1 1 of the draughtsealing member 8 is damaged or destroyed by the heat of the fire), thereby preventing smoke and combustion gases passing between the door and the door frame for a prolonged period. If the fire is on the same side of the door as the seal (i.e. if the opening of the channel 3 containing intumescent material is on the same side of the draught-sealing member as the fire) the intumescent material protects at least the part 11 of the draught-sealing member 8 from the direct heat of the fire.It is desirable that the ends of the tubular part 11 are closed to prevent the intumescing material entering the tubular part.
Referring to Figure 2, a threshold seal 1 comprises a rigid elongate holder 2 of uniform section. The holder 2 defines a first longitudinal channel 3 having an opening 4 and a second longitudinal channel 5. The channel 3 contains a solid coherent mass of intumescent material 7.
The holder 2 further comprises a flange 12 for use in attaching the seal to a face of a door 15, adjacent the bottom of the door, as shown. The flange 12 may be fastened to the door by nails or screws, not shown. The holder defines, together with with the door 13, an opening 6 to the channel 5.
The channel 5 holds, between the holder 2 and the door 15. a member 8 of resilient material. The member 8 has a part 9 retained in the channel 5 and a blade 1 1 which protrudes from the channel 5 through the opening 6 and extends below the bottom of the door.
The holder is shaped to act as a weatherboard.
A baffle 20 may be provided in the channel 3.
The opening 4 of the channel 3 containing the intumescent material 7 is directed towards the blade 1 1, which acts as a guard or shield for the opening 4, protecting the intumescent material 3 both by shielding the opening 4 from view and by physically preventing or at least making difficult the insertion of a probe through the opening 4 into the intumescent material, for the reason discussed above with reference to Figures 1 A and 1 B.
The door is conventionally mounted in a door frame, by hinges or by pivots in the floor and in the head of the door frame. The direction of the opening movement of the door is indicated by arrow A. When the door is closed it abuts against stops of the door frame in conventional manner and the blade 11 sealingly engages against a water bar 17 provided fixed at the threshold of the door. The blade 11 thus seals against draughts and water at the threshold.
In the event of a fire, when the holder 2 and the intumescent material are subjected to elevated temperature, the intumescent material intumesces through the opening 4 forming a heat-resistant coherent mass 16, as indicated by dashed lines, which seals the threshold of the door against passage of smoke and combustion gases, even if the blade 11 is damaged or destroyed by the heat of the fire-and, if the fire is on the same side the door as the seal 1, protects the blade 1 1 from the direct heat of the fire.
The seal shown in Figure 3 is similar to the seals shown in Figures 1 A, 1 B and 2 except as described below.
The holder of the seal of Figure 3 is of generally rectangular section and the resilient member 8 has a part (not referenced) retained in the channel 5 of the holder and a blade 8 which engages a water bar 17 when the door is closed. The opening 4 is disposed adjacent the channel 5 and the blade 6 and is directed parallel to the blade 6.
The presence of the baffle 20 is optional. The seal of Figure 3, can be used, instead of a threshold seal as shown, as a stop seal i.e. mounted on a stop of a door frame to seal against the door when the door is closed.
In the embodiment described above, the holder 2 is preferably of material of high thermal conductivity in order to assist in conduction of heat to the intumescent material. For example, the holder 2 may be of aluminium or aluminium alloy.
Alternatively, the holder may be of plastics material.
The resilient material of which the member 8 is made may be, for example, heat-resistant and fireresisting or fire-retardant Neoprene.
It will be appreciated that the seals of the embodiment described can be fitted to the door stop or the door, as the case may be, without a groove or rebate needing to be prepared in the door stop or the door.
In manufacturing the seals, the channel 3 of the holder may be filled with intumescent material by filling the channel with a slurry or paste of material which hardens or is caused to harden to form the intumescent material such material is described in our patent no. 1 601131. Alternatively, a preformed strip of intumescent material may be inserted into the channel.
The opening 4 of the channel 3 may be present before filling the channel with the intumescent material or may be cut after filling the channel 3 with the intumescent material. The opening 4 may be an incipient opening, that is the holder 2 may be provided with a membrane or diaphragm which ruptures when the intumescent material 7 intumesces or melts when the holder is subjected to elevated temperature in the event of a fire so as to allow the intumescing material to expand out of the holder.
The exposed surfaces of the holder may be ribbed or fluted so as to prevent a larger conductive area to the heat of a fire.
The water bar 17 of Figures 2 and 3 may be replaced by a threshold bar or trough.
