Description

A DOOR LINING

Technical Field

The present invention relates to door linings. Background to the Invention

Door linings are used to line inside edges of doorways of buildings. A door lining provides a neat finish to a doorway, and provides a convenient structure to which a door can be attached.

An existing door lining includes a length of material, often wood, secured to each of the two vertical surfaces of the doorway (known as jambs), and a length of material secured to the horizontal overhead portion of the doorway (known as a head). A door is attached, via one or more hinges, to the door lining, and a door stop attached to the door lining acts to prevent the door from moving beyond a given point when the door is closed.

Existing door linings are typically manufactured to fit one of two standard widths: 106mm (4.25 inches) or 133mm (5.25 inches). These widths are considered as being building industry standards for door linings. Alternatively, a length of timber could be cut to a required size by a user in order to produce his or her own door lining.

When installing a door lining, such as the one described above, a skilled carpenter or builder is required first to cut each of the three lengths of material to the required size, namely to the size of the horizontal and vertical sides of the doorway. Secondly, the door lining may need to be sawn and/or planed and sanded to the exact width of the doorway into which the door lining is to be installed.

Significant skill, time and effort is thus required to install a door lining of the existing type. Summary of Invention

According to a first aspect of the present invention, there is provided a door lining having an adjustable width for covering a surface of a doorway, the door lining comprising a mount for mounting the door lining to said surface; and a pair of elongate covers attachable to the mount in a spaced apart manner, such that the elongate covers cover that part of the surface that extends beyond the mount.

An advantage of the elongate covers being attachable in a spaced apart manner is that their positions relative to one another can be decided when the door lining is installed. Of course, while the elongate members are attachable in a spaced apart manner, they are also attachable in a non-spaced apart manner or, in other words, abutting or touching one another. Thus, the door lining can be used to cover a wide range of widths of surfaces of a doorway.

The term "surface of a doorway" is intended to mean the surface of an edge of a wall through which a doorway is formed. Typically, there may be three such surfaces in a doorway - two substantially vertical surfaces and one substantially horizontal overhead surface.

The mount may be any element suitable for the purpose of having components mounted thereto, or acting as a support member to support such components that have been secured thereto. The elongate covers may be any elements suitable for the purpose of covering the part of the surface to which the door lining is installed, that is not covered by the mount/support member.

The door lining may include a door stop member attachable to at least one of the elongate covers. The door stop member may be configured to span from one of the pair of elongate covers to the other of the pair of elongate covers. An advantage of this feature is that the door stop member covers any fixings in the support member/mount and in the elongate covers. At least one of the pair of elongate covers may have a substantially L-shaped cross section. At least one of the pair of elongate covers may be arranged to abut said surface.

The door lining may include means for attaching the door stop member to at least one of the pair of elongate covers. The attachment means may comprise an interference fit attachment.

According to a further aspect of the present invention, there is provided a kit capable of being assembled into a door lining, the door lining having an adjustable width for covering a surface of a doorway, the kit comprising a mount for mounting the door lining to said surface; and a pair of elongate covers attachable to the mount in a spaced apart manner, such that the elongate covers cover that part of the surface that extends beyond the mount.

The kit may include a door stop member attachable to at least one of the elongate covers. Each of the pair of elongate covers may have a substantially L-shaped cross section.

The kit may include means for attaching the door stop member to at least one of the pair of elongate covers. The attachment means may comprise an interference fit attachment.

According to a further aspect of the present invention, there is provided a method of lining a surface of a doorway, the method comprising securing a mount to said surface; and securing a pair of elongate covers to the mount in such a way that the covers cover that part of the surface that extends beyond the mount.

The method may include securing a door stop member to at least one of the elongate covers. Brief Description of the Drawings

Embodiments of the invention will now be described, strictly by way of example only, with reference to the accompanying drawings, of which:

Figure 1 is a perspective view of a door lining according to an aspect of the invention installed in a doorway;

Figure 2 is a sectional view of a door lining according to an aspect of the invention, in a first configuration;

Figure 3 is a sectional view of the door lining of Figure 2, in a second configuration; and Figure 4 is a partial perspective view of the door lining of Figure 2 installed in a doorway.

Description of the Embodiments

Referring to the drawings, Figure 1 shows a perspective view of a doorway 10 formed in a wall 12. A door 14 is hung on hinges (not shown) to one side of the doorway, and can be opened or closed in a known way.

A door lining, labelled generally as 16, is attached to inside surfaces of the doorway 10. The door lining 16 will be discussed in greater detail with reference to Figures 2 to 4. For now, though, it is apparent that the door lining 16 includes elongate covers, or edge lining parts 18, 19, which are flush with the wall 12, and a door stop part 20 which extends outwards (that is to say, into the doorway) from the edge lining parts, and acts to restrict movement of the door 14 through the doorway 10 when the door is closed. A threshold 22 may be formed across the width of the doorway 10 at floor level.

The door lining 16 may be formed from any material suitable for the purpose. However, as it will be appreciated by those skilled in the art, door linings 16 are typically formed from wood, such as timber or medium-density fibreboard (MDF), which can be produced in lengths suitable for use with doorways. Forming door linings 16 from wood is also advantageous in that the door lining can be cut to a desired length. It will, of course, be appreciated that the door lining may be formed from untreated material, such as wood, or from a material which has been treated, for example wood which has been painted, or had a veneer applied thereto.

Although, in Figure 1, the door lining 16 is visible only on one surface of the doorway 10, it will be appreciated that the door lining extends around three of the edges of the doorway - the top, overhead edge (the head), and the two vertical edges (the jambs). Of course, in some embodiments, the door lining 16 may be attached only to one or two edges of the doorway 10, or to all three edges of the doorway and across the bottom edge of the doorway.

Figures 2 and 3 show sectional views of the door lining 16 in first and second configurations respectively. Referring to Figure 2, the door lining 16 includes a mount or support member 24, shown with hatching for clarity, a first elongate cover, or lining member 18, a second elongate cover, or lining member 19, and a door stop member 20. The elongate covers have, in this embodiment, substantially L-shaped cross sections. However, in other embodiments, the cross sections of the elongate covers 18, 19 may be a different shape. One of the pair of elongate covers 18, 19 may have an L-shaped cross section while the other of the pair of elongate covers has a different cross section. An advantage of the elongate covers 18, 19 having an L-shaped cross section is that they are able to abut the surface of the doorway 10, which improves the strength of the door lining 16.

In this embodiment, the door 14 is hung on the first lining member 18. However, it will be appreciated that the door could alternatively be hung on the second lining member 19. A groove 28 is formed along at least part of the length of the door stop member 20 and a groove 30 is formed along at least part of the length of the first lining member 18. One or both grooves 28, 30 may be continuous along the length of the first lining member 18 and/or the door stop member 20, or may be intermittent. One or more securing members 32, sometimes referred to as 'biscuits' due to their shape, are wedged and glued into the grooves 28, 30 to form an interference fit connection to secure the door stop member 20 to the first lining member 18. It will be appreciated that, in other embodiments, the groove 30 may be formed in the second lining member 19 instead of to the first lining member 18. Alternatively, different means for securing the door stop member 20 to the first or second lining member 18, 19 may used. For example, the door stop member 20 may be secured to the first and/or second lining member 18, 19 by an adhesive, or by nails or screws.

An advantage of using an interference fit attachment as described above is that, once the door stop member 20 is secured to the lining member 18, 19, the fixing is not visible. Thus the aesthetic look of the door lining is improved because the fixing used to secure the components together is not visible to a passer-by. Furthermore, an interference fit attachment such as the above-described biscuits adds strength to the attachment. It will be appreciated that the door 14 will close against the door stop member 20, so it is advantageous that the strength of the attachment of the door stop member to the first and/or second lining member 18, 19 is great enough to withstand large and sudden forces from the door. Additionally, forming an attachment using an interference fit is easier and quicker than by using screws or nails.

In addition to the groove 30 formed in the first lining member 18, one or more screw holes (not shown) may be formed in the first lining member, within or adjacent to the groove, for receiving screws for a more secure attachment to the support member 24.

In the configuration shown in Figure 2, the first and second lining members 18, 19 are shown abutting one another along an edge above the support member 24. However, turning to Figure 3, it can be seen that the first and second lining members 18, 19 are spaced apart and separated by a distance A. In the arrangement shown in Figure 2, the first and second lining members 18, 19 can be considered as being separated by a distance A=0. In other arrangements, such as that shown in Figure 3, the lining members 18, 19 are separated by a distance A>0. It will be apparent that, by increasing the separation between the first and second lining members 18, 19 (that is to say, by increasing the distance A), the width of the door lining 16 can be increased. The reason for the desire to increase the width of the door lining will now be discussed.

The width of an edge of a doorway 10 is determined by the thickness of a wall through which the doorway is formed. The door lining 16 of the present invention can be used to fit a range of widths of edges of doorways 10. In the configuration shown in Figure 2, the door lining 16 is at its smallest width. In that configuration, the door lining 16 is suitable for a relatively thin wall. In the configuration shown in Figure 3, the door lining 16 is suitable for lining the surface of a doorway through a relatively thicker wall. The door lining 16 of the present invention can, therefore, be considered to be adjustable to fit a range of doorways with relatively little effort required to install the door lining.

By using components (lining member 18, 19, support member 24 and door stop member 20) of different sizes, one is able to create door linings suitable for covering surfaces of doorways having a wide range of thicknesses.

In addition to the door lining 16 itself, the invention relates to a kit capable of being assembled into the door lining described herein. The kit includes the various components necessary to assemble the door lining 16. The components included in the kit may be significantly longer than required, so that a user is able to cut the components to the required length before installing the door lining. Alternatively, the components in the kit may be prepared to the required length, or approximately the required length (that is to say, the components are cut to the lengths required to fit a standard doorway). Either way, a user is not required to cut the door lining or any components of the door lining along their length. Only cuts across the length of the components may be required.

In one embodiment, the kit includes a single support member 24, a single first lining member 18, a single second lining member 19 and a single door stop member 20. A user is able to cut the individual components to the required length; that is two equal lengths for the vertical edges of the doorway, and one shorter length for the overhead edge of the doorway. In another embodiment, the kit includes, for each of the jambs and the head, three support members 24, three first lining members 18, three second lining members 19 and three door stop members 20, each of which is cut to a length equal to or slightly longer than the required length. With this arrangement, the kit can be packaged into a smaller, more compact size, and the user is able to cut each of the components to a required length, depending on the height and width of the doorway.

In some embodiments, the kit includes first and second lining members 18, 19 and a support member 24, but does not include a door stop member 20. The door stop member may be supplied and secured to the lining members separately, or omitted altogether.

The use of the door lining 16 will now be explained with reference to Figure 4, which shows a cutaway perspective view of a door lining according to the present invention, which has been installed in a doorway. In use, a user first cuts the components to the required lengths. The support member 24 is then secured to the centre of the surface of the wall 12 forming the edges of the doorway 10 using known securing means, such as adhesive and nails or screws.

The first lining member 18 is then positioned against the surface of the wall 12 on one side of the support member 24, such that an edge 18a of the first lining member lies flush with the wall 12. The first lining member 18 is then secured in that position to the support member 24 using known securing means, such as adhesive, nails or screws.

In a similar way, the second lining member 19 is positioned against the surface of the wall 12, on the side of the support member 24 opposite to the first lining member 18, such that an edge 19a of the second lining member lies flush with the wall 12. The second lining member 19 is then secured in that position to the support member 24 using known securing means, such as adhesive, nails or screws. Depending on the width of the edge of the wall 12 forming the doorway 10, the first and second lining members 18, 19 may be abutting one another (as shown in Figure 2), or may be secured to the support member 24 in a spaced apart manner with a gap formed between them (as shown in Figure 3). The support member 24 onto which the lining members, or covers, 18, 19 are mounted, and the covers themselves, together cover the entire width of the surface of the doorway. In other words, the covers 18, 19 cover that part of the surface that extends beyond the mount/support member 24.

If a door stop member 20 is required, then it is secured using the 'biscuit and groove' interference fit arrangement discussed previously, to the first lining member 18, thereby covering any gap between the lining members 18, 19, and covering and screws and other fixings in the lining members and in the support member 24.

The door lining described herein is capable of being installed in a doorway in which the edge of the wall through which the doorway is formed varies in width between the top and the bottom of the doorway. For example, on such a wall, a door lining of the existing type would need to be planed and sanded to match the shape of the surface of the doorway to which the door lining is be installed. However, a door lining constructed according to the present invention can be installed on such a wall by tilting one or both of the lining members 18, 19 slightly away from a vertical position.

In Figure 4, a door 14 is also shown in a closed position. In that position, the door 14 abuts the door stop member 20, and is substantially aligned and flush with the edge 18a of the first lining member 18. The space where the door 14 fits when closed is known as a door rebate. Thus, it will be appreciated that the relative locations of the grooves 28, 30 of the interference fit securing arrangement are arranged such that the distance from an edge of the door stop member 20 to the edge 18a of the first lining member 18 is substantially equal to the thickness of door 14 intended to be hung in the doorway 10. That is to say, the door rebate must be sufficient to receive a door 14 when the door is closed. Persons skilled in the art will appreciate that numerous variations and modifications will become apparent. All such variations and modifications which become apparent to persons skilled in the art are considered to fall within the scope of the invention broadly appearing before described.
