Definitions
- This invention relates to a cover.
- the general method of covering an opening, enclosure or outdoor area is generally by a window, door, or a covering of some description.
- 'door' or 'window' usually refers to a solid structure in a house or the like which can be transparent, translucent or opaque. In the case of a more temporary or flexible structure with an entrance opening, the need for a flexible cover that does the same job as a door or window becomes necessary.
- a cover can be something used to protect an underlying surface, enclose an opening or provide a shield or limitation.
- a cover can include the 'roll down' or zip type of cover that is positioned over a window or door to block out the elements, keep out insects, block light or provide privacy.
- a cover can be the side flap on the trailer that covers stored goods for transport.
- a cover can be the temporary roof that provides shelter from the sun or the elements to protect the underlying items.
- a cover can be an awning or temporary roof that also provides shelter from the sun or the elements to protect the underlying persons or items.
- a cover In all cases where a cover is required, the means of storing the cover when not in use, the application of that cover when required and the process of manipulating the same cover can be both tedious and time consuming.
- a retractable cover which includes
- the flexible material includes at least one biasing means.
- the retractable cover is used to cover surface.
- This surface could include an opening, area or enclosure as part of a structure; however, these are listed by way of example only and should not be seen to be limiting in any way.
- a method of attachment of a biasing means, as described above, to an existing cover for covering a structure characterised by the step of
- biasing means could be attached by a bonding glue or be sewn in, or encased in a sheath that could either then be sewn onto the cover, or be incorporated into the design of the cover initially, by folding the cover to form a sheath and sewing down each side of it to secure it in place.
- the sheath housing the biasing means could have a zip running the length of it so that the biasing means could be checked, replaced, maintained, or have a number of biasing means added to the first to increase the overall strength of the bias or reinforce the biasing means if the application of the cover had changed.
- the term 'sheath' in accordance with the present invention should be understood to mean a fitted cover that encases the biasing means and can either be for protection of the biasing means from corrosion or the like, or to enable the biasing means to be affixed to an existing structure.
- the sheath could be made of fabric, plastic or the like however these are listed by way of example only and should not be seen to be limiting.
- a device for securing a retractable cover as described above to an existing structure which includes
- the retractable cover includes an securing device for attachment to a structure.
- structure should be understood to include an opening, area or enclosure where a retractable cover can be attached to it, although these are listed by way of example only and should not be seen to be limiting.
- the term 'area' in accordance with the present invention should be understood to include a surface such as a wall, floor or the like, where a picture, drawing or feature is to be covered, however these are also listed by way of example only and should not be seen to be limiting in any way.
- the term 'enclosure' in accordance with the present invention should be understood to include a tent, caravan awning, house, caravan, truck trailer, stall, shop, fireplace, box or container, however these are listed by way of example only and should not be seen to be limiting in any way.
- a cover for a window, door or enclosure will generally retract in the up-down direction, a cover could also retract in a left to right direction, or at any angle, such as is the case with an awning or cafe outdoor seating cover.
- the term 'flexible material' in accordance with the present invention includes materials such as fabric, canvas, plastic, mesh, nylon or any material that is flexible.
- the term 'securing device' in accordance with the present invention should be understood to include a means that allows the retractable cover to be attached, in its entirety to an existing enclosure. This means could include a hook and pile fastener such as VelcroTM, buttons, domes, or metal clips, but these are also listed by way of example only and should not be seen to be limiting in any way.
- biasing means' in accordance with the present invention should be understood to include a means that causes the flexible material to move from an extended state to a compact position.
- This could include a strip which is under toroidal tension when in an extended state, e.g., elastic rubber or a tensioned metal strip such as a spring or a constant force spring, however, these are listed by way of example only and should not be seen to be limiting in any way.
- the biasing means is a constant force spring.
- the spring is a varied force spring, so designed that when in an extended state, the spring will begin to retract with a with a lesser degree of force compared to when it is in a partially retracted state. As the spring retracts further, it will do so with greater force.
- This is an advantage when affixed to a flexible material, as when in a fully extended state, the weight of material to be moved into a compact state is less than when the spring is partially retracted. When partially retracted, there is a greater weight of material to retract, so the increase strength of the spring allows the retraction to continue unaided.
- Varied force springs can include elgiloy and inconel based springs, inconel springs being high performance nickel alloys based springs that are corrosion resistance.
- Elgiloy springs are cobalt/chromium/nickel rich alloy springs with excellent fatigue life, corrosion resistance in numerous environments and are non-magnetic
- This biasing means allows the cover that it is incorporated into to automatically retract on release of the affixing means.
- This embodiment has the advantage of providing a quickly retracting cover that is simple, compact, and in the case of a tent or awning, can be incorporated into the design of said tent or awning without limiting the packing size in any way.
- a number of biasing means can be incorporated into a cover of, for example, a tent window or door, allowing, on release of any securing device, the cover to retract to the top of the window or door, where it can be secured by a hook and pile fastener such as VelcroTM or the like.
- a hook and pile fastener such as VelcroTM or the like.
- biasing means could be incorporated into a sheath or the like to increase the strength of the retracting means, or reinforce the first spring if the application of the cover has changed or the strength of the spring has decreased over time.
- Affixing means can include a hook and pile fastener such as Velcro , buttons, material ties, clips or magnets or zips, but these are examples only and should not be seen as being limiting in any way.
- Means for retrieving a retracted cover to pull it down to an extended state could include a string tied to the ends of the cover or elastic cords or the like, but these are by way of example only and should not be seen as being limiting in any way.
- the retractable cover could be applied to a tent window, whereby the cover is affixed to the tent by means of zips down each side of the cover. Upon retraction of the zips to a half way position, the cover would retract to that position also, allowing for the window to only be half covered, or at any position where the zips would be retracted to.
- the retractable cover attached to a tent window would be accessible from the inside, if the mesh covering the window were attached by a zip. The mesh zip could be undone and the window cover accessed and adjusted, then the mesh zip done up again. This has the advantage of allowing the window cover to be adjusted without having to step outside.
- retractable cover in the trucking industry allows for quick retraction of covers, speeding access to goods and ensuring the cover is keep out of the way of loading and unloading.
- Figure 1 is a diagrammatical representation of a retracted cover
- Figure 2 is a diagrammatical representation of an extended cover
- Figure 3 is a diagrammatical representation of a retracted cover being incorporated into a tent to be folded, in accordance with one representation of the present invention.
- FIG. 3 there is illustrated one embodiment of the present invention, being a tent (4) with a retractable cover positioned over either window or door. It is envisaged that an advantage is gained not only by the convenience of the automatically retractable cover, but also by the ability to disassemble and fold the tent to a compact size (5) without detaching the covers.
- the retraction mechanism does not provide a limitation to the minimum compactable size of the tent.
- the biasing means as represented by arrows 1 and 3 is by way of example only could also include a spring, but this example should not be seen to be limiting in any way.
- the attachments indicated by arrow 2 can be any standard attachment means, for example, a hook and pile fastener such as VelcroTM, buttons, material ties, clips or the like, but the example is not meant to be in any way limiting.
