Abstract

A flood resistant assembly including a first frame 1, a door 5 with a first seal 19, where the seal engages a second frame 3, and the second frame has a second seal 21 that engages the door. The first and second frames 1 and 3 may be adjusted to apply pressure to the seals 19, 21, which may abut one another. Part of the frame may extend beyond the door 1, and the other part 3 may be an L-shape that abuts the door. The frame and seals may extend about the periphery of the door, which may have four hinges 7, a multipoint lock and five locking points. The door may also be a stable door 9.

Description

Flood resilient door assembly

Field of the invention

This invention relates to flood resistant door assemblies which include a door and a frame for locating in an opening in a wall or the like so that the door may provide access into, for instance, a house or other building.

Background to the invention

Flood resistant door assemblies are used in locations where flooding may occur. The door of the assembly is capable of normal use as a door and ako provides a water-tight relationship with regard to a frame forming part of the assembly. The frame is in turn capable of providing a water-tight relationship between itself and the wail or the like which defines the opening.

Statements of the invention

According to the present invention there is provided a flood resistant door assembly for fitting a door to an opening in a wall or the like, the assembly comprising a door, a first frame for securing to the door and about at least a lower portion of an opening, a second frame for securing to the first frame, a first seal provided on the door an arranged sealingly to engage said second frame and a second seal provided on the second frame and arranged sealingly to engage the door.

Preferably the assembly is provided with means for connecting the second frame to the first frame which are adjustable to vary the pressure applied to the seals when the door is in a closed position.

Preferably the first frame extends beyond the door when the door is in a closed position. More preferably the second frame is a substantially L-shaped cross-section and extends around that part of the first frame that extends beyond the door when the door is in a closed position. Most preferably the second frame includes an edge which, when the door is in a closed position, abuts the doors. The second seal is then preferably provided in said edge and said edge engages the first seat when the door is in a closed position.

Preferably, the first and second frames extend about the entire the entire periphery of the door.

Preferably the first seal extends about the entire periphery of the door and the second seal extends about the entire periphery of the second frame.

The door may be of solid, one piece door or may alternatively be a stable door having an openable section in the top half of the door.

Preferably the door is mounted within the first frame by at least four hinges.

Preferably the door is provided with a multipoint lock. For instance such a lock with at least five ocking points.

1 5 Brief description of the drawings

The accompanying drawings are as follows: -Figure 1 shows a door frame forming part of a flood resistant door assembly of the invention and also showing both of the seals; Figure 2 shows a door of the assembly of figure 1; and Figure 3 is a transverse section of the door assembly of figure 1 installed in a wall.

Detailed description of the invention

The present invention will now be described, by way of example only, with reference to the accompanying drawings.

A flood resistant door assembly comprises first and second door frames 1 and 3and a door 5. Door 5 is hingedly connected to frame I by means of at least four hinges 7.

Door 5 is also provided with a multipoint lock (not shown) having at least five locking points.

Door 5 is in this cxamplc a "stablc" typc door with an openable section 9 in the top half of the door. This openable section allows a means of escape for people trying to escape from a property without having to open the main door which wou'd otherwise allow water to cause damage to the property. However, in other embodiments in accordance with the present invention the door may be a solid, one piece door.

Frame I extends around the entire periphery of the door, it is of substantially rectangular cross section and it may be secured to the wall 11 of a house or other building by means of fixing elements such as nails or screws 13.

Second frame 3 also extends around the internal peripheiy of door 5. Frame 3 is of substantially L-shaped cross section and may be fitted, as shown in Figure 3, to frame 1 by means of fixing elements 15, some of which extend in the plain parallel to the front face of the door and others extend parallel to the side edges of the door. These fixing elements are such that the outer frame 3 may have the appropriate amount of pressure applied so that the door seals (described below) are compressed to the appropriate extent to give efficient sealing when the door is closed.

Fitted into the rear face 17 of door S to extend around the entire periphery of the door is a first seal 19 which, when the door is shut, engages with an edge of frame 3.

Second seal 21 is positioned in the same edge of frame 3 and extends around the entire periphery of frame 3. When the door is in the closed position as illustrated in figure 3. second seal 21 engages door S and lies outside first seal 19.

In order to install the above described door assembly, the door 5 is first manufactured, treated and fitted into the first or inner frame 1. This operation takes place off-site.

typically at the workshop where the assembly is manufactured.

When on-site, frame I, together with door 5, is secured to wall 11 and then a bead of mastic/sealant 23 is applied to create a water-tight barrier.

Outer frame 3 is then positioned over inner frame I and screwed to the inner frame I so that the seals 19 and 21 have the correct amount of pressure applied to them. Then another bead of mastic/sealant 25 is applied giving the joint between the frame and the wall a double seat As described above, there is a double rubber seal on the door and frame. One seal is set into the frame and runs in a continuous bead from the top of one of side of the frame down to the bottom of the frame along the bottom and then returns to the top of the frame and also across the top. There is also a seal on the door which again runs in a continuous bead from top to bottom, along the bottom and then returns to the top.

When the door is locked the seals sit side by side creating a double seal.

In one embodiment of the present invention, the door is 45mm thick and is of solid construction allowing no water to seep through the door itself.
