Abstract

A folding door comprising two panels 1a 1b connected by a hinge (2 Fig 1) such that a gap (7 Fig 1) is defined between the two panels (1) in which a sealing member 11 is provided so as to seal the gap (7) when the door is in the closed position. There is also a trim member 12 attached to one of the panels (1b) and a recess 10 for the trim member 12 is provided in the other panel (1a), such that in the closed position, the trim member 12 is received within the recess 10 so as to conceal the sealing member 11. The locations for attachment of the sealing member and the trim member may be identical in shape and/or symmetrical in position to each other. The trim member attachment location may also serve as the location for the hinge. A method of assembling the door is also defined.

Description

FOLDING DOORS
This invention relates to folding doors.
S Folding doors, such as bi-fold or multi-fold doors, are well known. Typically, successive panels of such a door will be joined at their vertical edges with hinges.
The hinges will be provided on alternating faces of the panels, so that the panels concertina together face-to-face when open, or to extend to block an opening when closed.
It has been common to date to provide a gasket seal or brushpile between the panels on the face opposite to the hinge. This is generally black or grey and looks unsightly.
In prior art doors, this gap is around 10 mm and so is quite prominent.
According to a first aspect of the invention, there is provided a folding door, comprising two panels, in which the two panels are connected by a hinge on a first face of each of the panels, such that a gap is defined between the two panels and in a closed position of the door the size of the gap is minimised by the movement of the panels about the hinge, in which a sealing member is provided in the gap attached to one of the panels, arranged so as to seal the gap when the door is in the closed position, and in which there is provided a trim member attached to one of the panels and in which a recess for the trim member is provided in the other panel, such that in the closed position, the trim member is received within the recess so as to conceal the sealing member.
Therefore, not only will the trim member act to conceal the possibly unsightly sealing member, it will aid in sealing the gap against at least larger objects; the sealing member will still have the primary role in sealing the gap, but the trim member will assist with weather-tightness.
Each panel may comprise an edge at which the hinge is connected, the edges of the panels being adjacent and defining the gap. Each edge may have a profile, the profile defining at least one of the recess, a location for attachment of the sealing member and a location for attachment of the trim member. The profile of the edges, at least where the recess and the locations for attachment of the sealing member and of the trim member are defined, may be identical, and may be symmetrical to one another. The location for attachment of the trim member may also serve as location for attachment of the hinge. This is advantageous, as it means that a single profile can be used in multiple situations (for example, oppositely-handed hinges), thus reducing the amount of tooling required.
Typically, the profile will extend over a majority of the length of the edge.
According to a second aspect of the invention, there is provided a method of assembling a folding door, comprising connecting two panels by means a hinge on a first face of each of the panels, so as to define a gap between the two panels, the size of the gap in a closed position of the door being minimised by the movement of the panels about the hinge, attaching a sealing member in the gap to one of the panels such that, in the closed position, the sealing member seals the gap, and attaching a trim member to one of the panels such that, in the closed position, the trim member is received within a recess in the other panel so as to conceal the sealing member.
Each panel may comprise an edge at which the hinge is connected, the edges of the panels being adjacent and defining the gap. Each edge may have a profile, the profile defining at least one of the recess, a location for attachment of the sealing member and a location for attachment of the trim member; the method may comprise attaching a sealing member to the location for attachment of the sealing member and/or attaching the trim member to the location for the trim member. The profile of the edges, at least where the recess and the locations for attachment of the sealing member and of the trim member are defined, may be identical, and may be symmetrical to one another.
There may be two locations for attachment of the trim member; the method may comprise selecting one of the locations for attachment of the trim member and attaching the trim member to the selected location, and attaching the hinge to the other location for the trim member. This is advantageous, as it means that a single profile can be used in multiple situations (for example, oppositely-handed hinges), thus reducing the amount of tooling required.
The folding door may be in accordance with the first aspect of the invention.
There now follows, by way of example only, description of an embodiment of the invention, described with reference to the accompanying drawings, in which: FIgure 1 shows a horizontal cross section Through the hinged connection between two panels of a sliding door in accordance with an embodiment of the invention; and FIgure 2 shows a horizontal cross section through the hinged connection of Figure 1, with further detail of the seal and trim shown.
A folding door according to an embodiment of the invention is shown in the accompanying drawings. In this embodiment, two panels 1 of the door are joined by a hinge 2. The panels 1 are each of the form of a frame 3 holding a pane of glass 4. It can be seen that the hinge 2 is on a first side 5 of the panels, so that the folding door will operate so that, as the door is opened, the first sides 5 of the two panels 1 are brought together. This means that a gap 7 is formed, visible from the opposite, second side 6 of the panels 1. As the door is opened and the panels 1 are brought together about the hinge 2, the gap will enlarge.
The edges 8 of the panels in the gap have a profile, which is of consistent cross section along the vertical extent of the panels 1. On each edge, there are provided two seal recesses 9 for a seal 11 and two trim recesses 10 for a trim member 12, as will be described below. The profile is the same on both edges 8, and is symmetrical about a plane through the panes 4. As such, the two trim recesses 10 are on the outside of the profile, surrounding the two seal recesses 9.
The operation of the seal 11 and trim member 12 are demonstrated in Figure 2 of the accompanying drawings. In this Figure, the hinge 2 has been removed to show that the seal 11 and trim member 12 can be used with the same profile on oppositely-handed doors (that is, doors where the hinge is on the top or bottom of Figure 2).
However, in use the hinge 2 would be used, typically in the position shown in and discussed with respect to Figure 1.
In order to seal the gap, a rubber or brushpile seal 11 is attached (typically clipped, glued, slid or screwed) to one or both of the seal recesses 9. A seal 11 will typically be attached to the seal recess 9 of both panels, such that when the door is opened, so that the size of the gap 7 is minimised as shown in the accompanying drawings, the seals 11 engage one another. Alternatively, a single seal 11 can be attached to one panel 1, and can engage the other panel 1 to seal the gap 7.
S
In order to seal the gap, a trim member 12 is attached (typically clipped, glued or screwed) to the trim recess lOb furthest from the hinge 2 of one of the panels 1 (in Figure 2, the right-hand panel ib). The trim member will be colour-matched to match the frame 3. The trim member comprises a body 13, and a lip 14 extending therefrom.
The lip is received in the corresponding trim recess lOb of the other panel (in Figure 2, the left-hand panel la). Thus, the trim member 12 will prevent the ingress of large particles of debris into the gap, and will aid with weather-tightness. It will also conceal the seal(s) 11.
A trim member can also be attached to the trim recess lOa holding the hinge 2; this would then be cut to fit either above and/or below the hinge 2.
It is to be noted that the hinge 2 in Figure 1 is engaged into one set of the trim recesses 10 of both panels 1. Thus, the profile could be used for either handed doors; in Figure 2, the hinge could be attached to trim recesses lOa or lOb, with the trim member 12 being attached to the other trim recess lOb or lOa respectively. Thus only a single profile need be made for doors folding in either direction.
