Definitions

  • the present invention is concerned with an adjustable shutter of the type comprising a plurality of parallel slats pivotable about their longitudinal axis.
  • Such shutters are often referred to in the art as “jellowsy-type louvers ", “louverable shutters " , etc.
  • the invention is further concerned with a tilting mechanism and a locking mechanism for such shutters.
  • a louverable shutter comprises a plurality of parallely extending slats pivotable about their longitudinal axis. Such slats are fitted over openings such as windows and doors and occasionally are fitted also in sun roofs and are adapted for controlling the amount of light depending on the location of the sun.
  • Tilting the slats is facilitated by a suitable tilting mechanism typically comprising a common tilting member, e.g. a chain/cord, a rod, a belt etc. connected to all the slats, at their respective ends, whereby manipulating the tilting member entails corresponding tilting of the slats.
  • a suitable tilting mechanism typically comprising a common tilting member, e.g. a chain/cord, a rod, a belt etc. connected to all the slats, at their respective ends, whereby manipulating the tilting member entails corresponding tilting of the slats.
  • the present invention calls, by its primary object, for a louverable shutter assembly comprising a plurality of tiltable (louverable) slats parallelly extending and supported at their respective ends, wherein at least one end thereof is fitted with a tilting mechanism to facilitate tilting of the slats.
  • the shutter is a rollable shutter whereby tilting the slats is possible also at a partially rolled (partially opened) position of the shutter.
  • an adjustable shutter comprising a plurality of slats extending at adjoining relationship, each slat comprising a pivot axis parallel to a longitudinal direction thereof; each slat associated with a tilting mechanism at least at one end thereof, said tilting mechanism engageable with a corresponding tilting actuator displaceable in an axial direction normal to the pivot axis; the slats being linked to one another at adjoining edges of neighboring tilting mechanisms; each tilting mechanism comprises a guiding member and a tilting member whereby displacing the tilting actuator entails tilting of the slats about said pivot axis between open and closed positions, and whereby the slats are displaceable in the axial direction.
  • the tilting actuator is a cam-type member and the tilting member is a follower-type member.
  • the tilting actuator is a strap of rigid material formed with plurality of openings each defining a cam path engageable with a corresponding tilting member, the tilting actuator being displaceable in the axial direction so as to effect tilting of the slats, and in a direction parallel to the pivot axis so as to effect respective engagement and disengagement thereof with the respective tilting members of the slats.
  • the tilting mechanism comprises a pivot axle fixedly attached to a respective slat and pivotally extending through an associated guiding member, and a laterally extending tilting member engageable with the tilting actuator and coupled with a lever arm fixed onto said pivot axle, for pivotal displacement therewith.
  • a shutter locking mechanism to prevent unauthorized tilting of the shutters. Accordingly, tilting of the slats may be facilitated only by using the tilting mechanism whereby tilting is prevented by attempting to manipulate the slats.
  • the lever arm comprises a biasing portion for displacing the tilting member towards a locking latch fixed to the guiding member, whereby when a slat is in the closed position and an attempt is made to tilt the slat, the biasing portion displaces the tilting member into arresting engagement with the locking latch, thus preventing tilting of the slat.
  • Fig 1 illustrates a portion of an adjustable shutter in accordance with the present invention generally designated 30 .
  • the shutter may be a vertical shutter i.e. of the type fitted at openings such as windows and doors, or it may be horizontal or inclined e.g. of the type installed in sun/light windows, etc.
  • the shutter is illustrated with its slats 32 at their so-called closed position, i.e. coplanar arranged in a manner in which their adjoining longitudinal edges overlap, as known per se.
  • Slats 32 are pivotable about its pivot axis 34, which in the present example is horizontal.
  • the shutter 30 is a slidable shutter which is rollable so as to allow complete access through the opening at which it is fitted, wherein side edges of the slats 32 are slidingly received within a concealing support rail 36 fixed within the opening.
  • the support rail 36 also supports a tilting actuator 38 by means of flexible steel straps 40 and it also prevents tempering/picking of the tilting mechanism.
  • Each slat 32 is fitted at its respective end with a guiding member 46 accommodating a tilting member 50 laterally projecting and serving also as part of the locking mechanism, partially received within the guiding member 46 , as will become apparent hereinafter.
  • Tilting actuator 38 is in the form of a rigid strap of material (metal, plastic, etc) vertically extending and attached to the support rail 36 by flexible strips 40 , thereby rendering the support rail to be displaceable both in its axial direction (vertical in the present case) and in a direction parallel to the pivot axis 34 of the slats 32 .
  • Strips 40 are typically made of steel straps though other arrangements are possible too, for supporting the actuator 38 in a displaceable manner, as mentioned above.
  • the combined displacement of the tilting actuator 38 is obtained, for example, by an electric motor fitted with a suitable cam (schematically illustrated in Figs. 5A-5C) or by means of a manual actuator or lever (not shown).
  • the tilting actuator 38 is formed with a plurality of shaped apertures 56 which in fact serve as a cam engageable by tilting members 50 which correspondingly serve as followers.
  • the shape and dimensions of apertures 56 dictate the tilting regime of the slats between an open position and a closed position, as will become apparent hereinafter.
  • Each guiding link 46 is formed with an upper hook 58 pivotally engaged within a corresponding lower hook 60 of an adjoining guiding member 46 as can best be seen in Fig. 1B. It is further noticed that in the closed position the slats interlock with one another wherein an upper edge 64 of one slat is received in an overlapping manner within a corresponding receptacle 66 at a bottom edge of an adjacent slat.
  • Guiding member 46 accommodates pivot axle 34 fitted at one end with a stump 72 adapted for snugly fitting within aperture 74 of slat 32 .
  • a lever arm 78 formed adjacent a free end thereof 80 with a latch 84 for engaging with tilting member 50 and a slanted biasing portion 88 for clamping the tilting member 50 as will become apparent hereinafter.
  • Tilting member 50 is pivotally retained within guiding member 46 by block member 90 formed with a corresponding recess 92 receiving an axial portion 96 of the tilting member 50 and being essentially parallel with the free portion 50 engagable with the tilting actuator 38 as seen in Fig. 1A.
  • An intermediate portion 98 extends between the axle portion 96 and the tilting portion 50 .
  • Pivot axle 34 is received within a corresponding recess 93 formed in block 90 , parallel to recess 92 .
  • the locking mechanism fitted in the shutter illustrated in connection with the present embodiment may be omitted without interfering with the tilting function of the tilting mechanism.
  • the purpose of the locking mechanism is to prevent tilting of the shutters by tampering with the shutters.
  • Figs. 3 to 5 are directed to illustrating how slats fitted within a shutter in accordance with the present invention are tilted between closed and open positions whilst reference to the locking mechanism will be made in connection with the other Figures.
  • the shutter is illustrated in a closed position wherein the lateral engaging portion 51 of tilting member 50 extends not opposite an aperture 56 of the tilting actuator 38 .
  • This position does not enable engagement of the engaging portion 51 of follower-type tilting members 50 within the cam-type apertures 56 whereby, engagement is facilitated only upon displacement of the slats and their associated tilting mechanism vertically, in direction of arrow 122 or by displacing the tilting actuator 38 in a combined motion represented by arrow 126 , consisting of displacement along an axial direction thereof (essentially vertical) as well as displacement in an axis parallel to the pivot axis 34 (essentially horizontal).
  • Fig. 3B illustrates the shutter in a position after displacing the slats vertically downwards in the direction of arrow 122 , whereby lateral portion 51 of tilting member 50 extends opposite an opening 56 of the tilting actuator 38 , in a position suitable for engagement therewith.
  • Fig. 3C the tilting actuator 38 is shown after further displacement of arrow 126 whereby engaging portion 51 of tilting members 50 are engaged within openings 56 , the slats 32 still at their closed, untitled position.
  • Figs. 3D and 3E illustrate the shutter with slats 32 in their tilted, namely open position, wherein the tilting actuator 38 is further displaced along direction of arrow 126 further departing from wall portion 36 (Fig. 3D ), wherein the engaging arm portion 51 of tilting member 50 has reached practically the lowermost end of aperture 56 formed in the tilting actuator 38 .
  • the pattern of aperture 56 dictates the regime by which the slats 36 tilt, namely the tilting rate is dependent from pattern (length and steepness-i.e. the gradient of the opening) of the cam opening 56 .
  • the intermediate portion 98 of the tilting member 50 is received between latch 84 and biasing portion 88 , thus ensuring that the tilting member 50 remains engaged with lever arm 78 which constitutes the rigid connection, via pivot axle 34 and stump 72 to tilting of slat 32.
  • Figs. 4A-4C are top elevations illustrating the shutter assembly in three positions corresponding with Figs. 3A-3D respectively, wherein tilting actuator 38 is fixed to a vertical frame 133 formed with support rails 134 and 136 which support the guiding member 46 upon its vertical displacement during rolling of the shutter, and which together with extension portion 138 conceal the tilting and locking mechanism so as to prevent tampering therewith. It is to be appreciated that a variety of such frames are possible, depending on particular configuration of the opening etc.
  • Fig. 4A corresponds to either of the positions illustrated in Figs. 3A and 3B , wherein the tilting actuator 38 is at its retracted position namely, wherein engaging portion 51 of tilting member 50 is disengaged from the apertures 56 formed in the tilting actuator 38 .
  • Fig. 4B corresponds with the position of Fig. 3C , wherein the engaging portion 51 of tilting member 50 is engaged within a corresponding aperture 56 of the tilting actuator 38 , thus slats 32 are still in their closed, un-tilted position.
  • Fig. 4C corresponds with the position illustrated in Figs. 3D and 3E , wherein the tilting actuator 38 has completed its displacement and has vertically displaced to its extreme position, whereby shutter 32 has tilted into its open position.
  • Figs. 5A to 5C illustrate an embodiment exemplifying how the tilting actuator 38 may be displaced during a tilting sequence.
  • the tilting actuator 38 is fixed to a wall portion (not shown) by means of straps 40 made for example of a steel-spring leaf which constantly biases the tilting actuator 38 in an axially upward direction and in a horizontal direction away from the slats, as represented by arrow 142 .
  • An eccentric cam actuator 146 is fitted on a shaft of an electric motor 149 whereby rotation of the actuator 146 in the direction of arrow 152 entails displacement of the tilting actuator 38 in direction of arrow 128 , as explained hereinabove, entailing tilting of the slats 32 .
  • manipulating the tilting actuator 38 may be obtained by other arrangement as well, such as, for example, a manual lever, etc.
  • the intermediate portion 98 of the tilting member 50 is at all times engaged with lever arm 78 , though having sufficient clearance. Furthermore, as noticed from the previous Figures, at the un-tilted, closed position of the slats, portion 102 of the tilting member 50 remains engaged and biased by a biasing member 106 of the block member 90 fitted within guiding member 46 . Thus, when the slats 32 are un-tilted, the biasing effect on portion 102 of the tilting member 50 entails intermediate portion 98 to bear against locking latch 110 , as illustrated in Fig. 6A.
  • Preventing tilting of the slats 32 in a counter direction, namely inwards, is prohibited owing to the overlapping engagement of the slats, in accordance with one embodiment, as illustrated, for example, in Figs. 5A and 5B, wherein a bottom edge of the slats is formed at an outer face thereof with a projection 182 which overlappingly bears against a corresponding vertical projection 184 formed at a top edge of the slat 32 , thus preventing tilting of the slats inwardly (i.e. in a direction counter to that illustrated in Fig. 5C, i.e. counter clockwise ).
  • Figs. 7A-7C the locking mechanism is illustrated in the position (wherein for sake of clarity the actuator removed) in which the tilting mechanism is actuated by applying thereto lateral force represented by arrow 188 imparted thereto by the tilting actuator whereupon the intermediate portion 98 does not engage with the locking latch 110 and whereby it is free to pivot into the position of Fig. 7C , together with the interlinked lever arm 78 , entailing corresponding tilt of the respective slat 32 .
  • tilting member 50 and more specifically the intermediate portion 98 thereof, with an axial degree of freedom, between a position in which it is engagingly arrested by locking latch 110 , and a disengaged position whereby it is free to pivot about the axial portion 96 entailing pivotal displacement of pivot axle 34 and the associated slats.
  • Figs. 8A and 8B illustrate one embodiment in which the block member 90a is formed with a recess 92a which is essentially parallel with recess 93 accommodating the pivot axle (not shown), whereby axial portion 96 is displaceable within recess 92a only in an axial direction along arrows 192 and 194 , between a locked position illustrated in Fig. 8A , whereby intermediate portion 98 is arrested by a locking latch 110 and an unlocked position in which intermediate portion 98 is disengaged from locking latch 110 , against the biasing effect of biasing member 106 , as illustrated in Fig. 8B .
  • FIGs. 9A and 9B A different embodiment is illustrated in Figs. 9A and 9B, wherein the block member 90b is formed with a recess 92b slantingly extending with respect to recess 93 accommodating the pivot axle 34 (not shown) whereupon the tilting member 50 is swingably displaceable along arrows 196 and 198 between a locked position illustrated in Fig. 9A , wherein intermediate portion 98 is arrested by locking latch 110 and an unlocked position, against the biasing effect of biasing member 106 , whereby intermediate portion 98 is disengaged from locking latch 110 .
  • Figs. 10A-10H illustrate different biasing arrangements for biasing a tilting member into engagement with a locking latch 110 of a block member.
  • the respective block member pivotally accommodates a pivot axle 334 connecting lever arm 78 with slat 32 as disclosed in connection with all the previous embodiments.
  • block member 200 accommodates an axle portion 202 received within a bore 204 and biased by means of coiled spring 206 bearing at one end against a shoulder 208 of the block member 200 and at an opposed end against an annular rim 210 of the axle portion 202 , biasing the tilting member, namely the intermediate portion 212 in the direction of arrow 214 .
  • tilting member is biased in the direction of arrow 220 by means of a compression spring 222 fitted within a bore formed in block member 224 applying force on the axle portion of the tilting member.
  • Fig. 10C is similar to the embodiment of Fig. 10B, whereby a leaf-type spring 230 received within a recess 232 applies biasing force on axial portion 236 of the tilting member, thus biasing it in the direction of 238 .
  • a different concept is illustrated wherein arm portion 240 of the tilting member is articulated to one end of a coiled spring 242, another end thereof fixed within the stump portion 246 within the slat 32 , thus giving rise to a biasing force in the direction of arrow 248 .
  • Fig. 10E The arrangement illustrated in Fig. 10E comprises a leaf-type spring 250 having a first arm 252 secured to block member 254 and a second arm 256 secured to axle portion 258 of the tilting member, whereby the leaf-spring is a compression spring in which arm 256 is biased towards arm 252, giving rise to biasing the intermediate arm 260 in the direction of arrow 262.
  • a biasing arm 270 made of a resilient material is integral with the block member 272 and engaged with an end of axle portion 276 , giving rise to a tilting biasing force in the direction of arrow 280 .
  • Fig. 10G discloses a block member 284 formed with an integral spring portion 286 bearing against axle portion 288 and biasing it in the direction of arrow 290.
  • the biasing arrangement of Fig. 10H comprises a leaf-type spring 294 riveted at 296 to lever arm 78 , with an opposed end thereof 298 bearing against the intermediate portion 300 , thus giving rise to a biasing force in the direction of arrow 306 .
