Definitions

  • the present invention can be included within the field of motorized roller shutters.
  • the object of the invention relates to a motorized roller shutter, applicable to closure of windows, doors and other wall openings.
  • roller shutter constructions also called shutters or closures
  • said shutters include horizontal parallel slats which define a panel of slats, where the slats are selectively maintained together or separated to respectively prevent or allow the entry of air and light through the shutter.
  • US2921628 discloses a shutter provided with elongated connection extensions for the slats with size limitations in the light and air openings.
  • FR1508003 shows another type of roller shutter of cheaper production, whose slats, with open and weak structure, are connected to one another by connection elements threaded in openings made in the slats, which gives rise to frequent breakages.
  • ES0225708U shows a roller shutter on a roller, with horizontal bars connected together by tie-rods articulated as connection elements, the bars of which may be approximated or separated with the assistance of a cable or wound on a roller and guided between rails disposed opposite in side jambs connected to one another by a lower profile.
  • the shutter bars can only be separated from or brought closer to one another to be wound up or down.
  • connection elements external to the slats, which are flexible elements, such as cables or fibres, inserted in perforated arms which protrude from the ends of the slats, so that their breakage is easy.
  • connection elements external to the slats, with rotatory joints trimmed with rubber wheels to allow the silent sliding in the side jambs between which the shutter runs for its winding or unwinding.
  • said rotatory and sliding movements of solid surfaces with respect one another increase the noise and possibility of interfering in the operation of the closure, and cause an increase in friction between the relatively mobile parts, and therefore, their wear, and also require low friction materials to reduce friction and wear to a minimum.
  • interferences may occur in the operation of the roller shutter.
  • These roller shutters are also relatively expensive to produce and assemble-dismantle for the repair or replacement of the slats.
  • the panel of slats which include this type of devices can be wound and unwound by motor, e.g. on the motor casing or on a roller disposed behind the lintel of the opening to close.
  • the present invention discloses a motorized roller shutter to close openings which provides the selective option of allowing visual access to inside the opening, and lighting and ventilation of the opening.
  • the shutter comprises a panel of slats to close an opening, and also comprises connection elements to connect consecutive pairs of slats, one of the slats of each pair located above and the other below.
  • connection elements comprise first connection elements, to connect the slats of a pair.
  • the first connection elements in turn comprise an upper member pivotably connected to a lower part of the slat located above, and a lower member pivotably connected to an upper part of the slat located below.
  • first connection elements also comprise a connection shaft located at an intermediate point between the two slats of the pair, and whereby the upper member and the lower member are pivotably articulated to one another, and the first connection elements further comprise a torsion spring attached to the upper member and with the lower member to exercise on the upper and lower members a recovery force which tends to relatively pivot the upper and lower members with respect to the connection shaft to approximate the slats of each pair.
  • the shutter is designed for closing a defined opening in a wall, wherein a door, a window, etc. is installed; for example, although not exclusively, in commercial premises.
  • the shutter comprises a panel composed of a plurality of horizontal, consecutive and parallel slats (1, 2, 43) comprising upper slats (1, 43) and a lower slat (2).
  • the upper slats (1, 43) are preferably equal and comprise in turn a plurality of first upper slats (1) and a second upper slat (43) located below to the first upper slats (1).
  • the lower slat (2) is placed below the second upper slat (43), in the lower part of the panel.
  • the slats (1, 2, 43) are guided, preferably at their ends, as shall be explained below, between two opposite guide rails (21) disposed in two side jambs (20), which can be interconnected by a lower profile (not represented) or even with the vertical sides forming part of a frame (not shown) the lintel of which may include a box (not represented) for the winding of the shutter.
  • connection elements (8, 44, 49) where each connection element (8, 44, 49) interconnects a pair of adjacent slats (1, 2, 43), one of which occupies a lower position and another an upper position.
  • the connection elements (8, 44, 49) are preferably located on both sides of the slats (1, 2, 43).
  • the connection elements (8, 44, 49) comprise first connection elements (8) which are articulated.
  • a first connection element (8) comprises an upper member and a lower member, where the upper member is connected to the lower part of the slat (1, 2, 43) located above, whilst the lower member is connected to the uppermost of the slat (1, 2, 43) located below.
  • the upper member and the lower member are articulated to one another by means of a connection shaft (18) located at an intermediate point between the two slats (1, 2, 43).
  • the figures show first pivots (6) and second pivots (7), with the first pivots (6) to rotatably attach the upper member of the first connection element (8) to the lower part of a slat (1, 2, 43), and with the second pivots (7) to rotatably attach the lower member of the first connection element (8) to the upper part of a slat (1, 2, 43).
  • the pivots (6, 7) may be materialized in various forms.
  • the slats (1, 2, 43) comprise first housings (4) and second housings (3), where the first pivots (6) are housed in the first housings (4), and the second pivots (7) are housed in the second housings (3).
  • the housings (3, 4) pass through the slats (1, 2, 43), so that the pivots (6, 7) can be formed by bars housed in the housings (3, 4) and which protrude from said housings (3, 4) by their ends.
  • the housings (3, 4) may be blind, so that the pivots (6, 7) are connected to the housings (3, 4), externally protruding.
  • the first connection element (8) additionally comprises a torsion spring (15), which is preferably mounted coaxially with the connection shaft (18).
  • the torsion spring (15) incorporates a first branch (16) coupled to the upper member, and a second branch (17) coupled to the lower member, so that the branches (16, 17) exercise on the respective upper and lower members a recovery force which tends to bring each pair of two adjacent slats (1, 2, 43) closer to one another.
  • the upper and lower members are formed by first plates (9, 10).
  • the figures illustrate that the upper member comprises two first upper plates (9) opposite one another and articulated to the first pivot (6), and the lower member comprises a first lower plate (10) articulated to the second pivot (7), wherein the first upper plates (9) are articulated to the first lower plate (10) by means of said connection shaft (18).
  • first plates (9, 10) in the members of the first connection element (8) has an anti-intrusion effect, to avoid unauthorized access or vandalism.
  • the first lower plate (10), or alternatively any of the first upper plates (9), incorporate a protuberance (19) whereon the second branch (17), or alternatively the first branch (16), rests to favour the joint between the two adjacent slats (1, 2, 43).
  • the lower slat (2) and the second upper slat (43) are not connected by a first connection element (8), but by a second connection element (44), which is not articulated, so that it does not allow significant separation and approximation between the lower slat (2) and the second upper slat (43).
  • the second connection element (44) may be configured in various ways, many of them already known in the state of the art. It is preferred that there are two second connection elements (44), one on each side of the slats (1, 2, 43).
  • the second connection element (44) comprises a second plate (11) to be articulately connected, for example, by screws (13) to said second upper slat (43) and lower slat (2), for example, in particular, to the housings (3, 4).
  • This allows a certain relative displacement between the second upper slat (43) and the lower slat (2), to be able to articulate the necessary movement of the shutter panel, but without allowing a sufficient space to be defined to facilitate unauthorised access.
  • the second plate (11) comprises an elongated grommet (12), also called elongated hole, in the upper part, to connect to the second upper slat (43), whilst with the lower slat (2) the connection occurs by means of direct fitting in its respective joint shaft.
  • Bushings (14), for example of nylon, are mounted on the pivots (6, 7), in particular at free ends, opposite the connections with the slats (1, 2, 43).
  • the jambs (20), which are situated at the sides of the panel of slats (1, 2, 43), are longitudinally covered by guide rails (21) wherein the bushings (14) slide.
  • An actuation motor (not shown), for example of reversible type, controlled by a remote control, is connected to the panel of slats (1, 2, 43) to achieve its winding or unwinding, depending on whether it is actuated in one direction or another, so that the panel displaces along the guide rails (21).
  • the shutter of the present invention advantageously comprises a locking device which makes it possible to lock the raising of the panel, once it has reached a closed position wherein the panel completely occupies the opening.
  • a locking device which makes it possible to lock the raising of the panel, once it has reached a closed position wherein the panel completely occupies the opening.
  • the slats (1, 2, 43) may incorporate in their upper part, or in their lower part, dampers (5, 42), such as of silent block- type for example, of rubber, which in the figures have been represented in the lower part, and which dampen the contact between consecutive slats (1, 2, 43) or between the lower slat (2) and the ground.

  • the cam portion (45) is configured to contact by means of interference with the lower part of the lower slat (2), and cause rotation of the retaining element (24).
  • the ratchet portion (46) is configured to hook the lower slat (2) and cause locking of the panel, preventing the raising of the panel when the panel has reached the aforementioned closed position.
  • the retaining element (24) is operated to tilt between a locked position, wherein there is interference between the ratchet portion (46) with the lower slat (2) and therefore it prevents the raising of the panel, and a released position, wherein said interference no longer exists and therefore it allows raising of the panel.

  • the first supports (22) are separated by a distance greater than the length of the slats (1, 2, 43), and opposite, in closed position, the lower slat (2), although preferably positioned retracted in relation to the lower slat (2) in order to facilitate the opening or closing in the tilting of the retaining element (24).
  • the ratchet portion (46) hooks the second slat (2) in the corresponding bushing (14) of said second slat (2).
  • actuate the tilting of the retaining element (24) uses a lever (34) articulated on a lever shaft (33) and equipped with two arms (35, 36), which are defined as a first arm (36) and a second arm (35).
  • the first arm (36) is connected to the retaining element (24) and the second arm (35) is connected to an actuation mechanism (47), so that, in locked position, when the actuation mechanism (47) acts on the second arm (36) of the lever (34), the first arm (36) in turn moves the retaining element (24) to release the interference with the lower slat (2) and allow the raising of the shutter panel.
