Description

ROLL-UP SHUTTER WITH OPENABLE SLATS AND

MECHANISM THEREFOR

Technical Field

The present invention relates to shutter systems. More particularly, the present invention relates to roll-up shutter systems with openable slats that can allow the passage of air and light.

Background

Prior art roller shutter systems typically comprise slats, a roller tube (i.e. a spindle) for rolling the slats, a rotor (or manual lever) for winding the roller tube, and guides in which the sides of the slats slide during raising and lowering.

In some cases an electric motor is typically inserted in the roller tube and attached to it. The motor is typically operated and controlled from a pushbutton panel, or a remote controller. In other cases a mechanical device, such as linkage rods with ball joint heads or equivalent solutions, can be used for winding the roller tube and the rolling slats.

Typically, the raising of the slats is performed by hooking elements, which cooperate with the hooking elements on the slats, and which connect the individual slats to each other vertically when they move in the vertical direction during raising and lowering of the shutter curtain. IL 37506 discloses rolling shutters with automatically turning and blocked slats. The publication describes a system of rolling shutters and blinds, composed of a number of horizontal, parallel spaced, adjustable slats, which are joined at each end with chains or bands moving in fixed vertical rails; the described shutters are rolled up around a roll, placed above the rails. Nevertheless, the described system is limited.

EP 2722475 discloses a roller shutter, comprising metallic slats, which has a structure and a mechanism for tilting the slats in addition to rolling up or rolling down the shutter curtain like a traditional roller blind, using an electric motor or mechanical devices able to rotate the roller tube of the shutter curtain. The described roller shutter comprises a fixed supporting frame comprising two guide channels shaped to enable the vertical sliding of a roller curtain comprising a plurality of slats which can be tilted simultaneously by a mechanism operated by the roller tube. The described roller tube is attached to the masonry structure above the opening where the roller shutter is inserted and is connected by a drive mechanism to a source of rotary power which rotates the roller and thereby enables rolling and unrolling of the shutter curtain on the roller tube. However, the described roller shutter is costly.

It would therefore be desired to propose a system void of these deficiencies. Summary

It is an object of the present invention to propose a roller shutter system which can be rolled up and down like a traditional roller blind and where its slats can be tilted and opened, in order to allow the passage of air and light. It is another object of the present invention to propose a durable roller shutter system which can be installed for wide openings.

It is still another object of the present invention to propose a cost effective roller shutter system which can be rolled up and down and where some of its slats can be opened and closed when the roller shutter system is rolled down.

It is still another object of the present invention to propose a durable roller shutter system having tiltable slats.

Other objects and advantages of the invention will become apparent as the description proceeds.

Preferably, the roller shutter system further comprises end caps, which house the slats rotation elements that are located at the ends of said slat rows. In some embodiments, the slat rotation elements house a slat rotation mechanism, which is operably connected to a tiltable slat.

In some embodiments, the roller shutter system can be installed in openings wider than 1.6 meters.

In some embodiments, the roller shutter system can be installed in openings greater than 3 meters.

Preferably, rung is assembled from one or more profiles, made of aluminum, metal, plastic, or wood.

Preferably, the tiltable slat is assembled from one or more profiles, made of aluminum, metal, plastic, or wood.

In one embodiment, the tiltable slats are tilted electrically.

In one embodiment, the tiltable slats are tilted manually.

In one embodiment, the tiltable slats are tilted using a protrusion.

Detailed Description

The terms of "front", "rear", "down", "up", "bottom", "upper", "horizontal", "vertical", "right", "left" or any reference to sides or directions are used throughout the description for the sake of brevity alone and are relative terms only and not intended to require a particular component orientation.

Hereinafter, parts, elements and components that are depicted in more than one figure are referenced by the same numerals.

Fig. 1 is a diagram of an embodiment of a roll-up shutter system with a shutter roll-up/down mechanism, which may be manual and/or electric, according to an embodiment of the invention. The shutter system 12 may include a plurality of tiltable slats, such as slat 14, and may include a plurality of narrow intermediate non-tiltable connector rungs, such as rung 16. In this diagram the slats are tilted and depicted in the open position, in order to allow the passage of air and light. The tiltable slats and the rungs are depicted, in this diagram, in a single structure 50, i.e. a curtain, of the roll-up shutter system 12. The connecting rungs may be made of plastic, aluminum, wood, or any other rigid material, for maintaining the integrity of said structure of said roller shutter system. The tiltable slats, which may operably connect between two adjacent rows of the rungs, may be tilted in relations to the structure 50 of said shutter system, for allowing the passage of air and light, while said shutter system structure is lowered down. The shutter system 12 may typically have a top cover 100, for covering the rolling mechanism of the roller-up mechanism, and may typically have an associated frame with vertical side shutter-guide members 200. The shutter system 12 can be rolled up/down manually and/or via a motor.

Fig. 2 is a diagram of an embodiment of a roll-up shutter system, as described in relations to Fig. 1, having two structures that are interlocked together side by side, according to an embodiment of the invention. According to some embodiments it is possible to interlock a number of structures together in a single roll-up shutter system in order to cover a wide opening. In some embodiments, the interlocking of the structures side by side may be done using interconnecting caps, such as interconnecting cap 26. In one embodiment, the interconnecting cap 26 houses the slats rotation elements that are located at the ends of the slat rows. In one embodiment the interconnecting caps interconnect the rungs of the roll-up shutter system.

Typical prior art shutter systems have a maximum width of approximately 2 meters due to the limit in strength of the slats (one slat 30 per row), which are commonly made of aluminum. Additionally, it can be difficult for prior art mechanisms to tilt and open such wide slats. To reiterate, a particular feature of some embodiments of the invention is that each row of shutter slats 14 includes a plurality (typically repeat units) of nearly side-by-side shutter-slats that are horizontally interconnected in rows by slat rotation elements. Thus, very wide shutter systems can be produced because the slat rotation mechanism is not required to tilt and lift a long and potentially heavy slat.

It is a particular feature of some embodiments of the present invention that a the roll-up shutter system 12 can form wide horizontal rows, such as greater than 1.6 meters for openings greater than 1.6 meters, due to the rungs 16 which are operably connected between the rows of said tiltable slats 14, which maintains the integrity of the structure of said roller shutter system. In one embodiment, the roll roll-up shutter system can form wide horizontal rows greater than 2 meters for openings greater than 2 meters. In one embodiment, the roll roll-up shutter system can form wide horizontal rows greater than 3 meters for openings greater than 3 meters. In one embodiment the slats length may be between 0.1-3 meters wide. In one embodiment the slats length may be between 2.2-2.7 meters wide. In one embodiment the slats length may be more than 3 meters wide. In one embodiment the slats length may be no more than 3.2 meters wide. In one embodiment the length of a single structure of the shutter system may be between 0.1-3 meters wide. In one embodiment the length of a single structure of the shutter system may be between 2.2-2.7 meters wide. In one embodiment the length of a single structure of the shutter system may be more than 3 meters wide. In some embodiments the length of the shutter system may be between 0.1-3 meters wide. In some embodiments the length of the shutter system may be more than 3 meters wide. In some embodiments the length of the shutter system may be more than 4 meters wide. In some embodiments the length of the shutter system may be more than 6 meters wide. In some embodiments the shutter system may have more than one interlocking structures. In some embodiments the shutter system may have two interlocking structures. In some embodiments the shutter system may have more than two interlocking structures.

Fig. 3 is a diagram of parts of the roll-up shutter system, as described in relations to Fig. 2, where the top cover, and the shutter-guide members, have been removed for displaying the rolling mechanism, of the roll-up shutter system device, according to an embodiment of the invention. The roll-up shutter device 12 typically includes a spindle 11 for rolling and unrolling the shutter system structure 50, i.e. the curtain of the roll-up shutter system. Typically, the spindle 11 is attached to the masonry structure above the opening, where the roller shutter system is inserted, and when the spindle 11 rotates; it rolls or unrolls the shutter structure 50 on the spindle 11. The structure 50, of the roll-up shutter system, can be rolled up/down manually and/or via a motor 10 over spindle 11. The structure 50, as will be explained in greater detail in relations to Fig. 4, may include a plurality of tiltable slats 14 and a plurality of non-tiltable connector rungs 16. According to an embodiment, one or more rows of tiltable slats 14, may be operably connected between two adjacent rows of intermediate connector rung(s) 16. In some embodiments there may be only one tiltable slats 14, between two adjacent rows of intermediate connector rung(s) 16, and in some embodiments there may be only two tiltable slats 14, between two adjacent rows of intermediate connector rung(s) 16, and in other embodiments there may be three or more tiltable slats 14, between two adjacent rows of intermediate connector rung(s) 16. In some embodiments there may be one, or more, rungs 16 at the top and/or bottom of the structure 50, of the roll-up shutter system 12. Furthermore each connector rung 16 may be assembled from one or more profiles, made of aluminum, metal, plastic, wood, or any other rigid material. Each tiltable slat 14 may be assembled from one or more profiles, made of aluminum, metal, plastic, wood, or any other rigid material. The roll-up shutter system 12 may further include articulated, semi-rigid, or non-rigid, vertical shutter roll-up strips 18 non-fixedly connected between the spindle 11 and the top rungs 16, for rolling the structure 50, of the roll-up shutter system 12, up and down. In one embodiment, the shutter roll-up strips 18 may be assembled from, typically identical, repeat strip-segments.

Fig. 4 is an isometric view diagram of the bottom right corner of the structure 50, of the roll-up shutter system, as described in relations to Fig. 3, according to an embodiment of the invention. In some embodiments, at the outer ends of slats 14 (i.e. the extreme right and left of each row of slates) there may be end caps 25, which may house the slats rotation elements that are located at the ends of the slat rows. In some embodiments, the slat rotation elements may house a slat rotation mechanism, which is operably connected to a tiltable slat 14 through any of a plurality of ways (e.g. spring, cog system etc.) or via another component such as an axel such as shown in relations to Fig. 5. In some embodiments, the end caps 25 are configured to slidingly fit within vertical guide members (not shown) at the sides of the roll-up shutter system. The end caps 25 may be adjacently connected to a slat 14 at the end of the slat row, e.g. via an axle, or may be connected to a slat rotation element, which is in turn connects to an end slat 14 at the end of the row of slats 14.

Fig. 5 is an isometric view diagram of the bottom right corner of the structure 50, of the roll-up shutter system, as described in relations to Fig. 4, according to an embodiment of the invention. In the diagram, the bottom end cap 25 has been removed for depicting a rotation element according to one embodiment. In this embodiment, a small electrical motor 34 can tilt the slat 14, from close to open position, in order to let the passage of air and light. In one embodiment each slat of the shutter system has at least one such electrical motor. In one embodiment the small electrical motor 34 can also tilt the slat 14, from open to close position, in order to eliminate the passage of air and light. In one embodiment the small electrical motor 34 is connected to the axle of tiltable slat 14.

Fig. 6a and 6b are isometric views diagram of the bottom right corner of a structure, of the roll-up shutter system, where the slats may be manually tilted, according to an embodiment of the invention. In this embodiment, the tiltable slats, such as slat 14 may be manually titled to the open position. In Fig. 6b, the bottom end cap 25 has been removed for depicting a rotation element according to one embodiment. In this embodiment, the lever 26 may be connected to the tilting rods 27 of the tiltable slats, such as that by pulling lever 26 all the tilting rods 27 of the tiltable slats 14 are pulled which in affect tilts the tiltable slats to the open position. In some embodiments by pushing lever 26 all the tilting rods 27 of the tiltable slats 14 are pushed which in affect closes the tiltable slats. The tilting rods 27 may be located a certain distance from the axles of the tiltable slats as to allow the easily tilting of the tiltable slats, as known in the art.

Fig. 7 is an isometric view diagram of the bottom right corner of a structure, of the roll-up shutter system, where the slats are in the closed position, according to an embodiment of the invention. In this embodiment, the tiltable slats, such as slat 14 may be titled to the open position by lowering the structure 50 and operating a projecting leg, i.e. protrusion 33. In this embodiment, the structure may be lowered down to the floor, like any other typical roll up shutter system, however, once the structure 50 is lowered and the protrusion 33 reaches the floor, any further lowering will cause the protrusion 33 to push a lever (not shown) upwards. The lever may be connected to the tilting rods 27 of the tiltable slats 14, such as that by pushing the lever all the tilting rods 27 of the tiltable slats 14 are pushed which in affect tilts the tiltable slats to the open position. In some embodiments, when the structure is pulled up, all the tiltable slats 14 are lowered, by gravity or spring or by any other mechanism, which may close the tiltable slats to the close position.

Fig. 8a is a front view diagram of a part of the left side of a structure, of the roll-up shutter system, where the slats are in the opened position, according to an embodiment of the invention. Fig. 8b depicts a cross sectional view from the right side of the roll-up shutter system, where the slats are in the opened position, similar to the described in relations to Fig. 8a, according to an embodiment of the invention. In this embodiment, the tiltable slats 14 are opened by turning a cogwheel 34, i.e. a toothed wheel, attached to the axle of the tiltable slats 14. The lever 36 may have one or more teeth 37 at preset intervals corresponding to the locations of the cogwheels 34 of the tiltable slats 14. In one embodiment, the lever 36 may be pulled or pushed by a motor. In one embodiment the same motor that rolls the shutter system, e.g. motor 10 described in relations to Fig. 3, may be used for pulling and pushing the lever 36. In another embodiment the lever 36 may be pulled or pushed manually. In yet another embodiment the lever 36 may be pulled or pushed by a protrusion similar to the described in relations to Fig. 7.

Fig. 9a is a front view diagram of a part of the left side of a structure, of the roll-up shutter system, where the slats are in the closed position, according to an embodiment of the invention. Fig. 9b is a front view diagram of a part of the left side of a structure, of the roll-up shutter system, similar to the described in relations to Fig. 9a, where the cap 25 has been removed for the sake of brevity, according to an embodiment of the invention. In this embodiment, the tiltable slats 14 are opened by turning a mechanism 44 having a certain geometrical shape, rotatably attached to the axle of the tiltable slats 14. The lever 46 may be connected to the mechanisms 44 where the movement up/down of lever 46 may rotate the mechanisms 44. In one embodiment when the lever 46 is pulled upwards the mechanism 44 rotates clockwise which pushes the piston 44 right wards which cause the tiltable slat 14 to tilt to the open position, as depicted in Figs. 9c and 9d. In one embodiment, the lever 46 may be pulled or pushed by a motor. In one embodiment the same motor that rolls the shutter system, e.g. motor 10 described in relations to Fig. 3, may be used for pulling and pushing the lever 46. In another embodiment the lever 46 may be pulled or pushed manually. In yet another embodiment the lever 36 may be pulled or pushed by a protrusion similar to the described in relations to Fig. 7.

In one embodiment, using the roll-up shutter system as described above, can reduce the noise, typically associated with prior art roll-up shutter systems. Typical roll-up shutter systems usually have movable connecting elements with holes for allowing the passage of air and light, where these elements create much noise when the prior art roll-up shutter system is rolled up or down. However, in the roll-up shutter system, described above, the rows of rungs and slats are held together and rolled together without the movable parts which may, in effect, reduce noise. In one embodiment the roll-up shutter system, as described above, may be easier for cleaning, as the slats may be opened and cleaned from within.

Fig. 10a depicts a cross sectional view of the roll-up shutter system, where the slats are in the closed position, according to an embodiment of the invention. Fig. 10b depicts a cross sectional view of the roll-up shutter system, where the slats are being opened, similar to the described in relations to Fig. 10a, according to an embodiment of the invention. Fig. 10c depicts a cross sectional view of the roll-up shutter system, where the slats are in the opened position, similar to the described in relations to Fig. 10a, according to an embodiment of the invention. In this embodiment the tiltable slat 14 is opened by lowering the structure of the shutter system to the floor. When the structure reaches the floor the rows of slats, or a row rung and a row of slat, are pushed one against the other. Thus when the row of slate is pushed its unique shape causes it to start turning around its axle 55 effectively titling and the slat 14 to its open position as depicted in Fig. 10c. However, when the structure is pulled upwards and the rows of slats, or a row of rung and a row of slat, are pulled from one another the row of slate is pulled allowing the slat to turn back around its axle 55 to its closed position as depicted in Fig. 10a, based on gravity or spring or any other mechanism.

In some embodiments, Vertical shutter roll-up strips are operably connected to respective slat rotation elements (e.g. via a male/female connection), typically internally, however, alternatively, to the rear face thereof or even to the front face thereof.

In some embodiments, Vertical shutter roll-up strips extend nearly to the bottom of the frame or floor. As such, when the shutter is lowered, and the lowest end of the bottom slat initially touches the frame bottom (or floor), the bottom edge of the vertical shutter roll-up strips are spaced apart from the bottom edge of the frame (or floor). As a result, vertical shutter roll-up strips can yet be lowered further (e.g. moving down respectively to the slat rotation elements). In some embodiments of the present invention that tilting of the slats is actuated by the shutter roll-up strips being pushed downwards. The strips affect the slat rotation mechanism, which in turn tilts the slats. The aforementioned is action may occur after the shutter is completely closed. In some embodiments of the present invention that each slat is opened by its own associated slat rotation mechanism.

In some embodiments, the slat rotation mechanism, which causes the slats to tilt, is actuated by a strip actuator portion of the shutter roll-up strips.

In one embodiment, the slat rotation mechanism includes a curved channel in the side of the slat rotation element and a corresponding pin, which is configured to slidingly fit in the curved channel. The pin is held by the strip actuator portion of the shutter roll-up strips and is connected to the horizontally adjacent slat/slats, so that when the shutter roll-up strips are lowered the strip actuator portion moves downward relative to the slat rotation elements causing the pin to slide down the curved channel urging slat to tilt upward. According to an embodiment, when the shutter motor pushes the shutter downward until the bottom most slat row reaches the bottom of the shutter frame, or the floor, further downward pushing by the motor on the semi-rigid vertical shutter roll-up strips moves the strip actuator portion relative to slat rotation element actuating the slat rotation mechanism to tilt slats. The tilting of slats caused by the slat rotation mechanism can be actuated by any one of a number of slat rotation mechanisms, not merely the mechanisms described above, and some additional embodiments will now be described.

In some embodiments of the slat rotation mechanism includes an upper projection and a lower projection typically at opposite sides thereof. The axel may extend horizontally through the slats and the slat rotation elements. Each projection may be respectively connected to cables, a first cable and a second cable, at either ends of the projections. The first cable is connected to the upper projection and to a lower part of strip actuator portion, causing the slat to open during the downward movement of strip. Second cable may be connected to the lower projection and to an upper part strip actuator portion, causing the slat to close upon the upward movement of strip. The cables could be implemented as strips, chains, wire, and so on.

In some embodiments, the strip actuator portion of the vertical shutter roll- up strips includes a toothed rack and the slat rotation mechanism which includes a corresponding rotatable gear 44. When the vertical shutter roll-up strips are lowered relative to the slat rotation elements, the rack spins the gear causing slats to tilt open.

In some embodiments, the strip actuator portion, of the vertical shutter roll- up strips, has a torsion spring compressed between the slat rotation element casing and the strip actuator portion. Torsion spring has a wing that projects into or under slat. When the shutter roll-up strips are lowered relative to the slat rotation elements, torsion spring is no longer (fully) compressed (or at least not fully compressed) and the slats are urged open.

In some embodiments, the slat rotation mechanism includes small electric motors in the slat rotation elements and the electric motors operate tilting of slats. When the shutter roll-up strips are lowered relative to the slat rotation elements, at a certain distance, the strip actuator portion closes an electrical circuit to actuate the motors that tilt the slats open, and when the shutter roll-up strips are raised by the shutter motor the circuit is opened causing the small electric motors to tilt the slats back to a closed position.

In some embodiments, the roll-up shutter system has a mechanism for tilting and opening only some of the titlable slats. For example, the roll-up shutter system may have one mechanism for tilting the titlable slats of the upper part of structure of the shutter system while having another mechanism for tilting the titlable slats of the bottom part of structure of the shutter system. Thus the user may open only the tiltable slats of the upper part while leaving the tiltable slats of the bottom part in the closed position

While the above description discloses many embodiments and specifications of the invention, these were described by way of illustration and should not be construed as limitations on the scope of the invention. The described invention may be carried into practice with many modifications which are within the scope of the appended claims.
