Description:
ROMAN SHADE FOLD FORMING BATTEN Field of the Invention The invention relates to a roman shade fold forming batten.

Background to the Invention Traditionally roman shades have been formed by providing integrally located transverse battens at predetermined distances down a length of material. By attaching drawing cords to the material or battens it is possible to give the appearance of discrete lengths of material which can be drawn successively. This is essential to the roman shade style of window covering.

However the traditional roman shade is very labour intensive to manufacture. It requires the formation of batten pockets and stitching to connect the cords. As such roman shades are usually manufactured in standard drops designed for the more common window length.

When the drop of a window is unconventional it is necessary to have the roman shade especially made. This is expensive and there are significant delays in the delivery times of such shades.

Accordingly it is an object of the present invention to simplify the manufacture of roman shades.

Summary of the invention According to one form of the invention a roman shade fold forming batten including (a) retaining means to receive and releasably retain a fold of material formed transversely in a length of material; and (b) suspension mounting means located at one or more predetermined locations on the retaining means to receive suspension means.

In a first preferred embodiment of the invention, the retaining means is an elongated member having at least one longitudinal open mouthed cavity to receive and releasably retain the fold of material. Typically the open mouth of the or each cavity has a width approximately equal to the width of the fold of material.

In a further preferred embodiment, the retaining means further includes locking means to retain the fold of material in the or each cavity. Typically the locking means includes at least one locking member locatable in the or each cavity and sandwiching the fold of material between the locking member and the or each cavity. Preferably the or each locking member has a cross-sectional profile which approximates the cross-sectional profile of the or each cavity. For example the cross-section may be circular.

Preferably the suspension mounting means is a clip or ring to receive the suspension means.

With this type of batten it is possible to quickly and easily manufacture the roman shade or provide a kit for doing so. It is also possible for consumers to create such a shade themselves without specialist assistance.

Description of the Drawings The invention will now be further exemplified with reference to the drawings. The embodiments are illustrative practical embodiments and do not limit the concept of the invention.

In the drawings: Fig. 1 shows the "C" section with flange according to this invention.

Fig. 2 shows the solid round rod according to this invention.

Fig. 3 shows the application of the "C" section to a piece of cloth.

Fig. 4 shows the solid round rod used in conjunction with the "C" section locking the cloth into its position inside the "C" section.

Fig. 5 shows a roman shade made of several attached "C" sections.

Referring to Figs. 1 and 2 it can be seen that the section 1 has a flange 2 with a node 3 allowing for the attachment of a cord guide ring at any position along its length.

Typically the section 1 has the shape of a 3/4 circle or the letter "C". It has an opening 4 which is large enough to accommodate fabric 5 to be inserted along its length.

A round rod 6 may be fed in from either end of section 1.

Referring to Fig. 3 it can be seen that fabric 5 has been inserted into the opening of 4.

The "C" section 1 thus forming a folding point in the fabric 5.

Referring to Fig. 4 it can be seen that the solid round rod 6 has been inserted into the "C" section 1 to prevent the fabric 5 from escaping from the "C" section 1.

Referring to Fig. 5 it can be seen that with several "C" sections 1 attached with cord guide rings 7 it has created a roman shade 8. A cord 9 may be attached to the guide rings 7.
