Definitions

  • the present invention relates to a window shutter. More particularly it relates to a pull-up louvered shutter with axially-tiltable slats.
  • Common window roller shutters consist of a plurality of horizontal slats which are flexibly interconnected along their adjoining edges, allowing raising the shutter by winding it up on a horizontal shaft mounted above the window opening.
  • shutters When lowered, shutters protect the room from sunlight, providing shade, and when up the room is exposed to direct sunlight. Lowered shutters may also protect the room against unauthorized entry.
  • Venetian blinds provide a plausible solution, offering coverage of the window opening and yet allowing light to get into the room, however they do not comprise effective blockage against entry.
  • Venetian blinds comprise overlapping horizontal slats which may be raised and drawn together above the window opening by pulling a cord that interconnects the slats together. The whole structure of the Venetian blinds is suspended over the window opening by cords and can be easily be pushed aside.
  • Venetian blind slats are made of a thin pliable material, which is rather flexible and does not pose a real barrier against forceful entry.
  • each slat includes alternately bent edges of hook-shaped cross section which engage with the respective hook-shaped edge of the adjoining upper and lower slat and hold all slats in firm connection while the shutter is in raised or wound-up state, and their axes are at a maximum distance from each other, but which permit rotation of each slat out of engagement of adjoining edges, as soon as the bottom slat is in its lowermost position and the distance between the axes of adjoining slats is thereby reduced to a minimum, by means of stops on each slat defining this distance.
  • the slats are guided in parallel, preferably channel-shaped, guide rails mounted on both sides of the window, or door, opening and in the vertically positioned slots of rotors which are horizontally and rotatably mounted in the guide rails at a distance coextensive with the minimum distance between the slats.
  • Each slat is provided at its two ends with sideways protruding flat lugs, each engaging with a slot in the corresponding rotor as soon as the shutter has been lowered into its lowermost position, whereafter simultaneous angular displacement of all rotors and slats effects mutual disengagement of the hook-shaped edges of the slats, and rotation of all slats into louvered position. In this position every slat is firmly held in its respective rotors on both sides by a rim surrounding each rotor and the lug positioned in the rotor slot, preventing its forceful removal.
  • a certain drawback in the above mentioned shutter is the fact that if the user desires partial shading of the room, and for that purpose raises partially the shutter, leaving some of the window opening uncovered and some covered, the slats cannot remain in their horizontal alignment, where sunlight can pass through, but rather are positioned in their vertical alignment, blocking any light from coming through between them.
  • the inventors have learnt that most users prefer to have their shutter allow light to pass through it, even when partially raised, whereas full blockage of light is only required when the shutter is fully lowered.
  • Venetian blinds on the other hand, can be partially raised and still allow light to enter the room through the gaps between the slats.
  • the inventors have learnt that most users prefer to have their shutter allow light to pass through it, even when partially raised, whereas full blockage of light is only required when the shutter is fully lowered.
  • Yet another purpose of the present invention is to provide such a shutter which is suitable for the prevention of unauthorized entry, i.e. is firmly attached to the window opening and is made of strong durable material.
  • a pull-up louvered shutter comprising a predetermined number of solid slats adapted to be lowered or raised along substantially parallel rails provided on both sides of a window or door opening, said slats slidably attached at their ends to said rails, wherein said slats are aligned in parallel, connected to a collapsible suspending means suspended over said opening, whereby when said suspending means is it is slack state, said slats may be reoriented between a first horizontal overlapping orientation and a second vertical upright orientation by tilting means, and wherein said slats, when oriented in said first horizontal overlapping orientation may be raised and lowered along said rails.
  • said slats are each provided with two shafts, one on each of their ends whose distal ends are slidably mounted over said rails.
  • said tilting means comprises a predetermined number of aligned equidistant rotors along said rail , each provided with a plurality of bars, each bar located across one of said rotors, in parallel to the other bars, said rotors adapted to simultaneously be rotated, so that when the slat shafts are positioned over said bars, the rotation of said rotors causes said slats to tilt.
  • each one of said rotors is provided with a lateral lug which is engaged to a vertical slat that can be lowered or raised, thus simultaneously rotating the rotors.
  • said vertical slat is manually operated.
  • said vertical slat is operated using at least one motor.
  • said motor is located on or near said rail.
  • the louvered shutter further comprises a plurality of bars, each located and aligned between said rotors, so that when said rotors rotate, the bars on the rotors can be brought to be aligned with said plurality of bars, so as to allow said slats to be moved along said bars.
  • said suspending means comprise a chain of a plurality of links, interconnected in a loose connection by joints.
  • said suspending means comprise a chain of a plurality of links, interconnected in a loose connection by joints, each link length being half of the distance between the centers of two adjacent rotors, wherein each joint is alternately defined either by two adjacent links mounted rotatably over one of said shafts or over an adapter which connects between two links, halfway between two adjacent shafts.
  • the louvered shutter further comprises raising and lowering means for raising or lowering said shutter slat along the rail.
  • said raising and lowering means comprise a lever coupled to an end of a strap or cord, suspended from the top of said window or door opening, long enough to reach, when fully slack beneath the shaft of the lowermost slat of said plurality of slats, when said lowermost slat is positioned in its lowermost position at the bottom of the opening.
  • said strap is manually operated.
  • said strap is attached to a wheel coupled to and rotatable by a motor, said motor positioned over said opening.
  • said motor is further provided with transmission box and a switch adapted to allow a person to actuate the lowering or raising of said shutter slats.
  • said slats are made of aluminum.
  • said slats are made of plastic material.
  • a main aspect of the pull-up louvered shutter of the present invention is the provision of a movable louvered shutter, which can be lowered or raised with its slats in a laterally horizontal louvered orientation, and when lowered to its lowermost position, the shutter slats may be jointly oriented in a laterally vertical upright position, leaving no substantial gap between their adjoining edges, reoriented in the horizontal overlapping orientation, or any intermediary orientation.
  • a pull-up louvered shutter in accordance with a preferred embodiment of the present invention basically comprises two substantially parallel guide rails mounted on both sides of a window or door opening, a plurality of slats, aligned in parallel, positioned one over the other between the guide rails, provided with raising and lowering means, for raising or lowering of the slats when the slats are in a laterally horizontal louvered position, and tilting means for simultaneously tilting the slats between two positions, the first position being when the slats are in a laterally horizontal louvered position, and the second position being when the slats are in a laterally vertical upright position.
  • the later position can be assumed only when the shutter is in its lowermost position.
  • Figure 1 illustrating an elevated view of a part of the louvered shutter operating mechanism with the guide rail inside the guide rail housing, and a slat attachment.
  • the Figures generally depict only one side of the shutter, for the purpose of brevity, as the other side is basically identical (it being, in fact, a mirror-image of the side depicted in the Figures).
  • a guide rail 1 is mounted on each side of the window or door opening on which the shutter is installed.
  • the guide rail 1 houses an incorporated guiding and tilting mechanism 2 (whose details are explained hereafter).
  • FIG. 2 illustrating a front-side view of a part of the louvered shutter operating mechanism inside the guide rail housing, and a slat attachment.
  • the guide rail housing 1 is provided with a vertical longitudinal slot 17, so that shaft 15 with the slat connector 10 protrude out of it, whereas the rotor 16 remains inside.
  • Figures 3 and 4 illustrate a front-side view and a back-side view of a part of the guide rail mechanism with an attached slat.
  • the construction of the guide rail mechanism is in fact duplicated in a predetermined number of duplicates matching the number of the shutter slats.
  • Slat connector 10 comprises top arcuate support 25 and bottom support 24 having a projection which is supposed to nest within a corresponding recess (not shown in the Figures) on the slat surface to hold it firmly in place.
  • Rotor 16 is provided with a longitudinal bar 23 passing across the rotor, having two projections (one on each side) each in the form of a step, designed to fit into a matching recess on a bar 26 that extends between rotor 16 and the rotor of the next slat (see below).
  • Bar 26 is an integral part of a separator 21, which is a longitudinal flat member, designed to keep the rotors 16 in place, aligned and evenly spaced. There is a plurality of such bars, equidistant from each other along the guide rail.
  • Rotor 16 is provided with rim 32 designed to be fittingly seated inside a matching annular recess 33 on each of the ends of separator 21, so as to allow rotor 16 to rotate freely but prevent lateral displacement of the rotor. Note that as there is a plurality of rotors located along the rail, the bars across the rotors have to be aligned in parallel to each other, and rotate simultaneously, as will be explained hereafter.
  • Rotor 16 has a lateral lug in the form of a lever 27, having a cylindrical protrusion 28, which is designed to be engaged to a corresponding bore on a vertical slat 30 that runs along the guide rail, substantially parallel to the rotors.
  • vertical slat 30 When vertical slat 30 is raised it pulls lugs 27 upwards, causing the rotors 16 to rotate and consequently tilt the shutter slats to their interlaced vertical upright position.
  • tilting mechanism When vertical slat 30 is lowered, it pulls lugs 27 downwards, causing rotors 16 to rotate in the opposite direction, until bars 23 interlock with vertical bars 26, bringing the shutter slats to their lateral horizontal position, as shown in Figure 3.
  • the actuation of the tilting mechanism may be done manually, for example by a lever connected to the vertical slat which can be accessible by the person wishing to operate the tilting of the slats, or it can be done by engaging the vertical slat 30 to a motor (or several motors) located along the guide rail housing or near it, and actuated by a switch.
  • Shaft 15 bearing on one end the slat connector 10 has on its other end a U-shaped block 31 adapted to be slidably mounted over bar 23.
  • U-shaped block 31 bearing shaft 15 and the shutter slat connected to it should be positioned substantially over the axis of rotation of the rotor 16.
  • rotors 16 need to be aligned, evenly spaced, equidistant from each other, and shaft 15 and the rest of the shutter slats' shafts (not shown in the Figure) need to be similarly equidistant. This is accomplished by a chain of solid links 4, to which all shafts 15 are connected, the chain suspended from the top of the window opening, or from above it.
  • Links 4 are interconnected in a loose connection by joints, each link 4 length being half of the distance between the centers of two adjacent rotors. Each link 4 has a U-shaped connector 19 on both ends. Each joint is alternately defined either by two adjacent links mounted rotatably over shaft 15 or over cylindrical adapter 18, which connects between two links 4, halfway between two adjacent shafts 15.
  • each shutter slat is provided with a flat rim 34 on one lateral edge, and an elevated flat rim 35 on the other edge, which are designed to fit and overlap when the shutter slats are tilted to their vertical upright position.
  • the lower rim when the slat is in the vertical orientation
  • the shutter slats are suspended from the top by the chain of links, in its slack state, connected to the shafts 15 as described herein.
  • Each shaft 15 is positioned over a rotor 16, with the u-shaped block 31 positioned substantially over the center of rotation of the rotor 16. In this state the slats may be rotated to the louvered position or to the vertical upright orientation, or to any intermediary orientation.
  • the lowermost slat is raised, causing the links between this slat and the slat over it to collapse and fold sideways, and allowing the lowermost slat to be drawn nearer to the slat over it.
  • the lowermost slat comes in contact with the slat over it, it pushes the second slat upwards causing it too to be raised. Consequently if the raising operation is conducted for enough time, all slats are raised.
  • the lowermost slat needs to be lowered. As it is lowered the remaining slats are lowered too and when the chain of links is finally freely suspended, the slats realign over their corresponding rotors, ready to be tilted as desired.
  • Figure 5 is a lateral cross-section view of the guide rail housing.
  • the lowermost slat can be raised by a lever 36, which is coupled to the distal end of a strap or cord 37, suspended from the top of the window, optionally passing along the guide rail housing, long enough to reach when fully slack beneath shaft 15 of the lowermost slat, when it is positioned in its lowermost position at the bottom of the window opening.
  • Strap 37 can be manually pulled up, or can be attached to a wheel 40 that may be rotated by a motor 41, positioned over the window (see Figure 8 illustrating a window with a louvered shutter in accordance with a preferred embodiment of the present invention, installed over it), pulling up or lowering the strap as desired (depending on the direction of rotation of the wheel 40 which can be governed by a transmission box 42. operated by the user (by a switch electrically connected to the transmission box 42).
  • the axle of motor 41 may run over the entire window, and operate the raising and lowering mechanism on the other side of the window too, operating the raising and towering mechanisms on both sides of the window simultaneously.
  • guide rail housing 1 may also house a motor (or a plurality of motors aimed at operating the tilting mechanism, shifting vertical bar 30 between its positions.
  • a gathering box 44 may be installed over the window, so that the raised slats may be stored inside it when fully raised, totally removed from the window opening.
  • Figure 6 is a partial view of a louvered shutter in accordance with a preferred embodiment of the present invention, with several slats in their vertical upright orientation.
  • Figure 7 illustrates a partial view of a louvered shutter in accordance with a preferred embodiment of the present invention, with several slats in the horizontal orientation when raised.
  • the slats can be made of plastic material or other solid material, but are preferably made from aluminum or other solid material possessing enough strength to yield it resistant to withstand attempts of forceful breaking and entry.
