Description

ARCHITRAVE SUPPORT AND ARCHITRAVE RELATING THERETO

TECHNICAL FIELD

The present invention relates to architrave supports and in particular to arch-shaped architrave supports and architraves for use above doorways, hallway entrances, windows and the like.

BACKGROUND ART

Arches can be used above internal or external doorways or windows to create a different aesthetic appeal compared with doorways having a straight section thereabove. Arches may be used above doorways in several ways. For example, the door may be rounded at its top having a complementary shape to the shape of the arch. Alternatively, where the door has a straight top, the space between the arch and the top of the door may be empty, or used to hold a single-piece glass panel, a multiple-piece stained glass feature, a wooden feature, and so on. Such arches tend to be either formed from plywood bent and formed into an arch shape or from metal such as mild steel or aluminium formed into an arch shape.

Where doorways or windows have architraves thereabout, the above described arches may be used to support curved sections of architrave, usually four equal curved sections, around the arch. The curved sections complement the shape of the arch and are glued or otherwise fixed to the arch. The curved sections are joined in series on the arch to form an arch-shaped architrave.

It is an object of at least one of the preferred embodiments of the present invention to overcome or ameliorate at least one of the deficiencies of the prior art, or at least to provide a suitable alternative thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE

INVENTION

Referring to the Figures, a preferred embodiment of present invention is a support or architrave support in the form of an arch 10 for supporting one or more architrave sections 12. The arch comprises ten planar portions 14, each having a pair of opposite oblique connection ends 16, each for connecting to an oblique end of another planar portion 16 or to a base support 18. The planar portions 14 are connected in series at their oblique connection ends 16 to each other to form the arch 10.

Each of the planar portions 14 are equal to each other in size and shape, each in the form of a trapezoidal prism. Preferably, the planar portions 14 are cut from a straight wooden plank to have an angle a of 9 normal to the plane of the wooden plank, as illustrated in Figures 3 and 4.

In the present embodiment, the planar portions 14 are joined in series by glue or otherwise attached mitre joints to form the arch 10, however may be joined by any other suitable joints such as a half mitre, a corner halving and so on.

As illustrated in Figure 5, the arch is adapted to support architrave sections 12 on an architrave face, or end 20 of each of the planar portions 14. Figure 5 illustrates the arch having five architrave sections 12 thereon, however in use each planar portion 14 would preferably have a separate architrave section 12 attached thereto to complete an architrave along the arch 10.

While it is preferred that the number of architrave sections 12 correspond to the number of planar portions, it is not essential. For example, there may be fewer or more architrave sections 12 than planar portions 14.

In a preferred use of the invention, the arch lOis preformed and made available in a range of widths to complement a variety of door frame and window widths. The arch 10 may be load bearing, but it is not essential to be so. A skilled person can then purchase an arch of choice, and a length or lengths of desired architrave boards. The skilled person would install the arch 10, for example above a door frame, and cut equally sized architrave sections 12 to attach to corresponding planar portions 14 of the arch 10. Two door jamb lengths of the same architrave board would then be cut to a predetermined length to be attached to respective side door jambs. The two door jamb lengths of architrave would then be attached to their respective side door jambs and the architrave sections 12 attached to their respective planar portions 14 of the arch 10.

In another preferred use of the invention, the arch is made available in kit form of a predetermined number of planar portions 14 for joining together to form the arch 10. In alternative embodiments of the kit, the base support 18 either is or is not part of the kit.

The preferred embodiments have been described with reference to the arch being formed from ten equally sized planar portions 14 such that the arch is substantially semicircular. In alternative arrangements, the arch is formed from planar portions having different respective predetermined angles at their oblique connection ends, such that the height of the arch is either less than or greater than the width of the arch. For example, the angles may range from 8 to 150. In other alternative embodiments, the lengths of the respective planar portions for forming the arch may be different, and/or the number of planar portions for forming the arch may range from six planar portions to fourteen planar portions. In the latter embodiment, the planar portions making up the arch may be equally sized, in which case the angle of the oblique ends is adapted accordingly.

While the material of the preferred embodiments is described as wooden planks, it will be understood that they are not limited to this material. Suitable material may include plywood; laminated or non-laminated chipboard; suitable metals; plastic board, such as high density polyethylene; plasterboard; preformed plaster; etc. Also, the material used to form the arch 10 need not be the same material used to form the architrave sections 12.

The preferred embodiments have clear advantages over the above described prior art, in that the arch conveniently allows for the attachment thereto of architrave sections 12 cut from a straight plank or length of architrave or similar board to obtain an arch effect. Comparable prior art arches are pre-cut in a circular shape which is more expensive to produce and more restrictive in terms of outcome compared with the embodiments described herein.

While the invention has been described in reference to its preferred embodiments, it is to be understood that the words which have been used are words of description rather than limitation and that changes may be made to the invention without departing from its scope as defined by the appended claims.
