Description

SPECIFICATION Draught excluder, weather seal and/or smoke seal The present invention relates to a device suitable for use as a draught excluder, weather seal and/or smoke seal.
The device according to the invention is intended to prevent passage of draughts, water and/or smoke between two members which are relatively movable between open and closed conditions. Such members may be a door and its associated frame, a window and its associated frame, a door and the threshold of the door or two windows independently slidable in a common frame. The movable members may be pivotally movable with respect to each other, as e.g. a door hinged in a frame or may be translationally movable with respect to each other as e.g. a window slidably mounted in a frame.
Hereinafter for convenience, draught excluders, weather seals and/or smoke seals are referred to simply as draught excluders.
A known draught excluder for preventing or inhibiting draughts (and also a passage of water and smoke) between two relatively movable members comprises a rigid elongate holder and a resilient element retained by the holder. The holder defines a channel, the mouth of which is partially closed by inturned lips. The resilient element has a solid root portion accommodated in the channel and a sealing portion external to the channel, a linking portion extending through the mouth of the channel and interconnecting the root portion and the sealing portion, the lips of the holder retaining the root portion in the channel. In use of the draught excluder, the holder is secured to one of the two relatively movable members, the sealing portion of the resilient element sealingly engaging the other relatively movable member when the two relatively movable members are in their closed condition.The holder may be mounted on a stop or a frame of a door or window so that a face of the door or window when closed engages the sealing portion of the resilient element. It is also possible to mount the holder in a similar manner at the threshold of a door.
A disadvantage of the known draught excluder is that the resilient element may slightly laterally deform, becoming somewhat wavey along its length. This both looks unsightly and can diminish the efficiency of the sealing of the sealing portion against the member with which it engages.
The sealing portion of the resilient element may be a blade disposed at an acute angle to the plane in which the mouth of the channel lies.
Alternatively, the sealing portion may be tubular.
If the sealing portion is in the form of a blade, the resilient element is subjected to flexing when the relatively movable members open and close and this flexing tends to withdraw the first portion of the blade from the channel in the holder, particularly if there are protrusions or other irregularities in the member with which the blade engages, which cause relatively high forces to be applied locally to the blade.
Moreover, it is difficult to manufacture the resilient element to high tolerances. As a result, the root portion of the resilient element may be a loose fit in the holder and this may allow the resilient element to travel undesirably, when subjected to repeated flexing along the holder, may allow excessive lateral movement of the sealing portion, and may allow the resilient element to be unintentionally withdrawn from the holder. Alternatively, if the root portion is oversized, it may be very difficult to insert it into the holder.
The present invention aims to overcome or mitigate the above-described disadvantages of the known draught excluders.
The present invention provides a draught excluder comprising: a rigid elongate holder formed with a channel having a mouth defined by lips of the holder; and a resilient element having a root portion retained in the channel by said lips, a sealing portion external to the holder, and a linking portion interconnecting the root portion and the sealing portion, the linking portion being provided with at least one rib abutting an external face ,of the holder formed by said lips.
In use of the holder, the rib or ribs ensure that the sealing portion is maintained straight along its length.
The sealing portion may be an angled blade, i.e.
a blade at an acute angle to said external face of the holder, or may be tubular. Said acute angle is preferably in the range 30 to 600.
Preferably two of said ribs are provided on opposite sides of the mouth of the channel.
The invention is further described below by way of example with reference to the accompanying drawings, wherein: Figure 1 is a section through a first draught excluder according to the invention; Figure 2 is a cross section of the draught excluder secured to a door frame, an associated door also being shown; Figure 3 is similar to Figure 2 but shows the draught excluder secured to the door; Figure 4A is a section through a second draught excluder according to the present invention; Figure 4B is a section through the resilient element of Figure 4A; Figure 5 is a sectional view showing the second draught excluder mounted on a stop of a door; Figure 6 is a section through a third draught excluder according to the invention; Figure 7 is a perspective, partly cut-away, view of the third draught excluder secured to a door frame, an associated door also being shown;; Figure 8 is a perspective view of a fourth draught excluder according to the invention; Figure 9 is a perspective view of sash windows fitted with draught excluders as shown in Figure 8; and Figure 10 is a vertical sectional view through the sash windows.
Referring to Figures 1 and 2 of the drawings, a draught excluder 1 comprises an elongate rigid holder 2 and an elongate resilient element 3.
The holder 2 has lips 4 defining the mouth 5 of a channel 6 formed in the holder.
The resilient element 3 comprises a first or root portion 7 within the channel 6 of the holder, a linking bar portion 8 extending from the root portion through the mouth 5 of the holder, a blade 9 external to the holder and two ribs 10 on either side of the bar portion 8.
The root portion 7 is a loose fit in the channel 6 of the holder 2. Similarly, the linking portion 8 is a loose fit between the lips 4.
The blade 9 tapers slightly towards its free edge, the upper and lower surface of the blade, as viewed in Figure 1, being at angles of respectively 470 and 450 to an imaginary plane 11 containing the mouth 5 of the holder and the front face 12 of the holder. The root portion 7 is retained in the holder 2 by the lips 4. The ribs 10 abut against the face 12 of the holder. In Figure 1, the root portion 7 is shown for the sake of clarity of diminished size relative to the channel 6.
In use of the draught excluder 1, the holder 2 is secured to one of a pair of relatively movable members. E.g. as shown in Figure 2, the holder may be secured in a groove in a stop 15 fixed on part 13 of a door frame. As a door 14 is closed, free edge portion 9' of the blade 9 engages the door 14 and the blade 9 is flexed, the free edge portion 9' exerting pressure against the door to form a seal against the door and to prevent draughts between the door 14 and the part 13 of the door frame.
The ribs 10 assist in rigidifying the bar portion 8 and the root portion 7 of the resilient element 2 to hold the blade 9 straight and, by abutting against the holder, inhibit or prevent the flexing of the blade 9 causing movement of the root portion 7 wihin the holder even if the root portion is a loose fit within the holder. The root portion 7 thus remains substantially undisturbed within the holder and there is little, if any, tendency, for the root portion to be withdrawn from the holder by the repeated flexing of the blade 9 even where the free edge portion 9' of the blade engages protuberances or other irregularities on the door 14.
It will be understood that the root portion 7 can be easily slid into the channel of the holder from one end.
The holder 2 may be made of aluminium or aluminium alloy (or plastics or other suitable material) and the resilient element 3 may be made of rubber or a synthetic rubber such as Neoprene.
In an alternative arrangement as shown in Figure 3, the holder 2 is secured in a groove in the door 14 so that the free edge portion 9' of the blade 9 engages the stop 15 as the door is closed.
In the arrangement of Figure 3, the various parts of the draught excluder function similarly to as described above with reference to Figure 2.
Referring to Figures 4A and 4B, a draught excluder 1 is generally similar to that shown in Figures 1 and 2 comprises an elongate rigid holder 2 and an elongate resilient element 3.
The holder 2 defines a channel 6 having a mouth partially closed by inturned lips 4. A mounting flange 16 is coplanar with one wall of the channel 4. A first external face 12 of the holder is formed by the lips 4 and a second face 18 is formed by said one wall of the channel and the flange.
The resilient element 3 comprises a solid bulbous root portion 7, accommodated in the channel 6, a linking portion 8 extending through the mouth of the channel and a tubular sealing portion 19 external to the holder. The resilient element 3 also comprises a pair of ribs 10 and 10' disposed against the face 12 of the holder. As described above with reference to Figure 1, the root portion 7 and the linking portion 8 are a loose sliding fit in the holder.
The draught excluder 1 is shown only diagrammatically in Figure 5.
Referring to Figure 5, in use the holder 2 is mounted on a vertical or horizontal stop 15 of a door frame 1 3 by means of screws inserted in fixing holes 20 in the flange 6 of the holder. A door 14 mounted on the door frame opens and closes in the direction indicated by the doubleheaded arrow.
When the door is closed, it presses against the sealing portion 1 9 of the resilient element to effect sealing between the holder and the door. Also the sealing portion 1 9 is pressed against the stop 1 5 to effect additional sealing between the holder and the stop.
The ribs 10 and 10' serve to prevent lateral deformation of the resilient element 3 (i.e.
deformation parallel to the face 7) and to reduce lateral movement of the root portion 7 within the holder 2. The ribs further rigidify the resilient element 3 generally, prevent the sealing portion 19 being pushed laterally relative to the holder 2 to such an extent as to cause withdrawal of the root portion 7 from the holder and/or damage to the resilient element, and enable the resilient element to be retained firmly by the holder 2 despite large dimensional tolerances in manufacturing the holder and/or the resilient element.
The rib 10' may be in its free state of sufficient width to extend slightly beyond the face 8 of the holder so that sealing between the holder and the stop can be effected by the rib 10' pressing against the stop.
Referring to Figures 6 and 7, a draught excluder 1 is similar to those shown in Figures 1 and 4A but further includes a flange 1 6 integrally formed with a holder 2. The flange 16 has a row of screw holes 20, only one of which is visible in Figure 6.
The holder 2 may be fastened to a stop 15 of a door frame 1 3 by means of screws 1 7 passing through the screw holes 20' so that when the door 14 is closed the blade 9 of the resilient element 3 sealingly engages against the door.
Furthermore, the rib 10' sealingly engages against the stop 1 5 if in its free state it slightly extends beyond the face 8 of the holder.
It will be appreciated that the holder 2 can be mounted on any desired member, such as the stop 15 without a groove having to be cut to receive the holder.
The draught excluder shown in Figure 8 differs from that shown in Figure 7 in that instead of the flange 16, it is formed with an L-shaped portion 21 having screw holes 17 so that it can be fastened by means of screws to a desired member.
Figures 9 and 10 show lengths of draught excluder according to Figure 8 fitted in a sash window.
The sash window comprises two sashes 23 and 24 independently vertically slidable in a frame 25.
the draught excluder is cut to appropriate lengths for fastening to the windows as described below, lengths 26 of the draught excluder are fastened to the frame 22 so that blades 9 engage the vertical parts 28 of the sashes. Another length 29 is fastened to the upper horizontal part 30 of the upper sash 23 so that when the window is closed the blade engages the upper horizontal part 31 of the frame 25. Similarly a length 32 is fastened to the lower horizontal part 33 of the lower sash 24 so that its blade engages the lower part 34 of the frame when the window is closed.
Finally, a length 35 of the draught excluder is fastened to the underside of the lower horizontal part 36 of the upper sash 23 so as to engage the underside of the upper horizontal part 37 of the lower sash 24 when the window is closed.
It will be understood that the blades of the vertical lengths 26 of the draught excluder are in sliding sealing engagement with the sashes 23 and 24. The ends of the holders of each of these lengths of draught excluders should be "nipped" so as to grip the resilient element 3 and prevent it sliding out of the holder.
