Abstract
Description
- The present invention relates to a flexible drive mechanism for covering building openings and to coverings for building openings comprising such a mechanism
- Very large glass panels are often used in modern buildings or even on the complete surface thereof. Venetian blinds, shutters and the like are one solution for covering windows and doors as sunshade and they can have decorative effects as well. For lager openings or complete façades, the Venetian blinds' slats and shutter panels can attain very large dimensions both relating to width hereof as well as the longitudinal extension of the slats or panels. For installations of this kind, some kind of motorized drives can be employed for convenience, since the coverings are frequently mounted from the outside and in considerable heights. Traditionally the drives make use of electric motors where the rotary motion by some means are converted to linear motion in order to open and close said coverings.
- Traditional Venetian blinds are operated by pulley and cord mechanisms based on gravity. This method can be motorized, but does not by itself contribute to any support for the blinds, which must be accomplished in another way. It is not possible by this method to use horizontal motion Other solutions have been proposed such as
WO 2004/059116 where the rotary to linear conversion is done by means of a screw-threaded rod. This method offers a better support for the slats but lacks flexibility since this type of rotary to linear conversion is truly linear.US 3845669 discloses a partial bendable guide and a flexible rack drive system. Rack kind of drive systems make use of more than twice the length of the working distance of the object to be operated. - Shutter systems are frequently used for covering doors and gates for security or other reasons and are mostly opened in a vertical direction by means of chain or belt pulleys.
- On this background, it is the object of the present invention to provide coverings for building openings of the Venetian blinds or shutter types and in particular drive means for the same, which offer greatest possible freedom in design and implementation, horizontal or vertical.
- It is another object of the invention to improve the aesthetical effect by providing suspension and operation of the systems in a manner that ascertains proper alignment of all slats and panels in the shutter system in a predetermined way even in non-rectilinearity.
- These and other objects and advantages are achieved according to the invention by providing a support and drive mechanism, which can be tailored, free of previously known restrictions by combining straight portions and arced portions into an entirety or it can assume any other shape The drive mechanism can combine slat and panel support and drive means, and can be tailored as an integral part of a building structure and is fully scalable to suit any dimensional requirements.

Tilting of the carriage can for instance be prevented by providing the carriage with at least two roller or slider means at a suitable distance from each other in the longitudinal direction of the carriage,
- According to a second aspect, the present invention relates to a folding shutter system comprising a plurality of slats substantially extending in parallel with each other and interconnected in a displacement system, characterised in that said slats comprise rotational axles substantially in the centre part of each longitudinal end of each slat and other rotational axles in the rear part of each longitudinal end of each slat and in the front part of each longitudinal end of each slat, and a connecting rod connecting each front rotational axle through and with the centre rotational axle on the neighbouring slat with the rear rotational axle in the slat next to the neighbouring slat in a pantograph-like mechanism, and the distance between connecting points of said connecting rod being substantially equal to the distance between said centre and rear axles in same slat, and said rear axles are extended to include roller or slider means for displaceable engagement with a track in a guideway.
- According to a third aspect, the present invention relates to a folding shutter system comprising a plurality of panels hinged together in an accordion fashion with an outer hinge system and an inner hinge system, characterised by the ends of the panels connected by the inner hinge system extending away from the hinge forming an end part of the ends of each panel, and at least one end part is equipped with one or more rollers or sliders extending away from the panels for rolling or sliding along and guided by a guideway, and at least one of the end parts of one end panel having means for fixation to said guideway, and at least one of the end parts of the opposite end panel having means for fixation to said carriage running in the guideway, the guideway being formed such that disengagement between the rollers or sliders is prevented during operation of the system

- Embodiments built on the idea of a carriage running in a bendable or workable profile comprise at least one guideway, said guideway accommodating drive means for said carriage. It is part of the present invention that the drive means can adapt to the curvatures of said guideway. One simpler embodiment is carried out as a straight only version, but still has the advantages of the integral solutions.

The guideways for each side of the Venetian blind system are secured to the framework of the building opening to be covered. The innerrotational axles 16 in each end of theoutermost slat 10 are secured to the guideways in a way rendering rotation of the slat possible, but sliding in the guideway is not possible. The inner rotational point opposite saidoutermost slat 17 can be coupled by means of carrier means 8 to said guidedcarriage 6. Whenever the carriage is driven closer to said innerrotational axles 16 in each end of theoutermost slat 10 and is coupled to the inner rotational point opposite saidoutermost slat 17, the slats will operate asfig. 4 c-a , and when the carriage is driven away from said innerrotational axles 16 in each end of theoutermost slat 10, the Venetian blind system will operate asfig. 4 a-c . As can be seen infig. 4 a-c , the slats by this invention will operate in synchronism with each other in a way so as to close the building opening, wltile the slats are tilted in continuation of each otherfig. 4c and opening the building opening will bring about the slats being stacked fag. 4 a. By individual tailoring of said distances and their relationships, the present invention brings about Venetian blinds capable of changing directions following said curvature of the profile and said guideway. Guiding and fixation means for the slats and rods can be separated from the guideway drive system or means for guiding said slats, or can be integrated in the drive systems guideway. This type of folding shutter system is often referred to as Venetian blinds. - Yet another embodiment of the invention is a folding shutter system as shown in
fig. 5 . The shutter system comprises a plurality ofpanels 20 arranged in pairs and connected by hinges in theinner edges 22 andouter edges 21, respectively. Each panel in a pair connected by the inner hinges 22 is extended away from the hinge and away from each other forming asupport 23 for one ormore guide rollers 24.Extensions 23 withguide rollers 24 can count one or more along the edges of the panels along the inner hinge end side. The rollers rolling in theguideway profile 2 will support and guide the panels. Theguideway profile 2 infig. 5 corresponds to thetrack 4 of theguide profile 2 infig. 1 . Theouter guide rollers 24 are equipped with means 8 for coupling to a guidedcarriage 6 infig. 1 or one end can be anchored to theguideway profile 2. The structure and arrangement ofextensions 23 and guiderollers 24 on theextensions 23 of thepanels 20 bring about a predetermined and synchronized aesthetical movement of the panels whether the shutter systems operate rectilinearly or curvilinearly or in combination. Guiding and fixation means for the panels and guide rollers can be separated from the guideway drive system or means for guiding said rollers, or can be integrated in the drive systems guideway if applicable. Thepanels 20 can take any form and shape suitable for its purpose and can be made of any material. The system described is perfectly suitable for horizontal and vertical operation or any direction in between. Various situations of the embodiment are shown schematically infig. 6 and in a perspective view infig. 7 . - The basics of a third embodiment of the invention is seen schematically in
fig. 8 a and 8 b, respectively. Theflexible drive shaft 5 is composed of two oppositeconvoluted parts spindle drive motor 1. As for the preceding embodiments, thedrive shaft 5 can turn both ways and hence the flexible drive system will initiate movement of drivencarriages drive shaft 5 comprisingparts figs. 9a to 9d , where four intermediate positions during opening of panels are shown, but other realizations can be accomplished. - It is understood that although the drive mechanism comprising a rotary and flexible drive shaft described in preceding paragraphs of the description can be used to guide and drive the systems shown in
figures 4 to 7 andfigure 9 , other guide and drive systems may alternatively be used for this purpose. Likewise, the mechanism for converting rotary motion to longitudinal (linear or non-linear) motion may also be used for other purposes than for guiding and driving the systems shown and described in the present specification without departing from the scope of the invention.
