Definitions

  • the present invention relates to a roller shutter for windows and doors that allows air to flow through with or without passage of light. Therefore, it intends to substantially improved the capabilities of existing roller shutters without adding significant cost.
  • PVC extruded roller shutters are the cheapest and most widely used on the market today.
  • these existing roller shutters as well as the similar aluminum roll formed shutters have an important limitation. They are either slightly open letting air and light through, or closed in which case no air or light can pass. If a user wants to enjoy the evening air, the shutter must remain partially open in which case the air will be able to flow through the holes, but so will the morning light. If the user does not want to be awakened by the morning sun rays the shutter must be completely closed in which case there will be no evening air flow either. Also, to avoid the passing sun rays to be even stronger, holes are very narrow and therefore will only allow the passage of a minimal amount of air. Therefore, a need exists for an improved roller shutter that can let more air through with or without light passage.
  • Patent US 6,874,560 refers to a security metal roller shutter of the type used, for example, to close the front of a store.
  • These security shutters are made of steel and are designed in such a way that, when closed, they can be pulled open, but if somebody tries to push them open from the bottom, the shutter will jam against the sides of the guide channels and block.
  • the construction includes a moving pivoting connecting slat between every main slat holding them together. This pivoting connecting slat may look similar to the one used in the present invention but actually works in a very different manner.
  • the slat of the present invention is wider and contains holes to let air through. This slat is narrow, solid and has no holes because it is meant to carry out a different function.
  • the slats of the present invention have pins which function as an axis allowing them to pivot within the limits imposed by the guide channels.
  • This shutter is designed to work in the opposite manner so that, if pushed from underneath, the moving pivoting connecting slat which has no axis, pivots toward one of the sides of the guide channels and jams the shutter. It is important to point out that the shutter in the present invention is meant to be made of PVC, not metal.
  • Patent Application USSN 2010/012,279 refers to a roller shutter, which has metal pivoting slats that are either extruded or roll formed. It is meant to be used to close securely the front of stores, for example, but adding to existing models a better protection against rain. When in the open position, air comes through and, when closed, air can still pass in smaller quantities while providing better protection against bad weather. Although functions seem similar, the way it works differs significantly from the present invention.
  • the pivoting movement of the slats is achieved by arms that connect the slats between them, not by an axle pin as in the newly invented shutter.
  • the design of the shutter disclosed in the cited document will not work for PVC shutters; it has to be made of metal.
  • the newly invented shutters of the present invention are held together by the perforated secondary slats which are threaded into the longitudinal hook receiving grooves in the main slats and, hence, leave no open spaces between slats.
  • the shutter of the present invention is a single continuous flexible sheet, similarly to the conventional PVC shutters widely used today, which does not allow sliding a hand through it. In the metal shutter of the cited document, when open, there are free spaces between slats.
  • Patent Application DE 10 2006 005 750 refers to a newly designed slat which is meant to be built into a standard aluminum shutter in at least one or more units per shutter.
  • the basic roller shutter of which the new slat is to be a part is the standard roller shutter made of roll formed aluminum slats of the type that, when open, let air and light pass through the holes and, when closed, hide the part which contains the holes in the hollow part of the upper slat and so on.
  • This newly developed slat that is designed to let more light and air through, of which at least one can be intercalated in the standard shutter functions as a lid. When the intercalated lid formed element is opened, it flaps up letting light and air through the resulting open gap.
  • the opening lid looks very much like the main slat of the shutter of the present invention, it actually works in quite a different manner.
  • the lid of the mentioned document shows hooks that look like the longitudinal hook receiving grooves of the shutter of the present invention but, in fact, they are only hooks added to the ends of the lid which, in combination with side arms, lift the lid.
  • the lid of the Patent Application DE 10 2006 005 750 document does not comprise axle pins which allow slats of the shutter of the present invention to pivot but, instead, it uses side arms which flap the lid up and down producing a wide open space which lets air and light through.
  • conventional prior art PVC or aluminum roller shutters use slats that are all identical and insert in each other. When slightly open a part of the slat containing narrow holes is exposed, allowing air and light to flow through. When closed, the upper part of the slat containing the holes is inserted within the lower hollow part of the next slat, and so on. In this position no air or light is able to flow through.
  • the prior art slats are long enough to fit into the guide channels attached to the walls of the building, slide up and down within them and are unable to pivot.
  • the improved roller shutter of the present invention herein disclosed allows the slats to pivot. Except for one lower slat that is longer and works conventionally, the rest of the slats are cut shorter so that they do not reach the guide channels. At each end of the slat, protruding guide pins are attached. It is these guide pins that slide up and down within the lateral guide channels and allow the slats to pivot.
  • the main slats are held together by perforated secondary slats, which pivot inversely to the main slats and tilt them.
  • the slats of the present invention are of new design and are intercalated with perforated secondary slats. These perforated secondary slats have hook shaped sides which are threaded into the longitudinal hook receiving grooves in the upper and lower rear parts of the main slats, thereby holding them together. They are kept in place, unable to slide out laterally, by the main slat side lids, and the side lids are kept in place by the guide pins.
  • the perforated secondary slats pivot inversely to the main slats to which they are alternately attached, in such a manner that when the shutter is in the down position, these perforated secondary slats are positioned at an angle facing downwards, while the main slats create a shade over them. In this position, air flows through freely while only a slight light reflection might be seen from the inside. No direct sun rays are able to pass. Consequently, since light passage does not need to be restricted, the holes are made much bigger, allowing a larger air volume to flow through.
  • the roller shutter has two positions: down-position, in which air flows through but no light; and up-position in which air and light flow freely through the holes.
  • down position the perforated secondary slat looks down. Air flows, light does not pass.
  • up position the perforated secondary slat is upright permitting air to flow through and light to pass.
  • This embodiment never closes completely. Air always flows through. When pulled up it winds into a roll slightly larger in diameter than existing models. It is recommended for users, who want air passage at night without light rays shining through in the morning, but want a closed shutter during daytime for sunshade, security or privacy reasons while having air flowing through and light seeping through, so as to have some light in the room.
  • the roller shutter also has two positions: down-position in which air flows through but no light; and up-position in which no air or light can go through.
  • down-position in which air flows through but no light
  • up-position in which no air or light can go through.
  • the disclosed roller shutters fit in existing guide channels, so that old shutters can easily be replaced by these new ones without requiring changing said guide channels.
  • the slats of the present invention swing forward when pivoting so that they use less than one centimeter of back space.
  • New wider deeper vertical guide channels were designed containing the pin and hiding the ends of the shutter slats behind a front rim that avoids the passage of any light ray that could seep through the edges, also achieving greater strength and security against burglary.
  • the new shutters should only be slightly more expensive than conventional PVC roller shutters.
  • the new shutters are also made of PVC and, while the prior art models only use one standard slat, the new shutters use the extruded main slat, the extruded perforated secondary slat, the extruded bottom slat slightly different in shape and length, and the injected end lids which act as a retainer for the perforated secondary slats so they don't slide out, as well as the injected guide pins. The end lids are held in place by the guide pins.
