Definitions
- Each end portion of the shutter, at which operatively engages a drawband for the foldable shutter, is guided in the guide rail arrangement.
- Each end of each of the slats carries a stop or latch pin which is arranged in substantially parallelly offset relationship with respect to the associated guide bolt and cooperates with an associated bearing surface or support provided at the guide rail arrangement.
- the spacing of each bearing surface or support from the associated guide surface of the guide rail arrangement is smaller than the spacing between the guide bolts and the stop pins and that the control groove extends between the associated guide surface and the bearing surfaces or supports.
- the present invention relates to a new and improved construction of foldable shutter or Venetian blind of the type wherein its slats or lamallae which are hingedly interconnected have associated with both of their respective ends or end faces a respective guide bolt cooperating with an associated guide surface of a guide rail arrangement having a respective control groove for each shutter end portion extending parallel to the associated guide surface, and at which guide rail arrangement there is guided each end portion of the shutter and with which shutter there engages at least one drawband.
- Yet a further significant object of the present invention relates to a new and improved construction of foldable shutter or Venetian-type blind which is relatively simple in construction and design, economical to manufacture, extremely reliable in operation, not readily subject to breakdown or malfunction, and provides for relatively noiseless use and positive fixation of the shutter slats in desired position.
- each slat end carries a stop or latch pin which is arranged in parallelly offset relationship with respect to its associated guide bolt and which cooperates with an associated bearing surface or support provided at the guide rail arrangement, and the spacing of the supports from the associated guide surface of the guide rail arrangement is smaller than the spacing between the guide bolts and stop pins and that the control groove extends between the associated guide surface and the associated bearing surfaces or supports.
- the shutter Owing to the use of guide rails or a guide rail arrangement and pins cooperating therewith, and which pins in turn are directly attached to the slats of the shutter, the shutter can be beneficially operated in a trouble-free manner, in other words can be unfolded without clam ping or binding, and each individual slat fold can be fixedly retained in its desired position. Consequently, with the shutter unfolded there prevails, optically considered, a uniform image, which, in the case where there are arranged a larger number of such foldable shutters at a facade or structure, is of decisive importance as concerns its aesthetic appearance.

- reference numeral 10 generally designates a foldable shutter or Venetian-type blind construction which comprises a foldable shutter 12 having substantially horizontally arranged slats, a shutter drive 14 and a guide rail arrangement 16 for the shutter 12.
- the foldable shutter 12 as the same has been illustrated on an enlarged scale in FIG. 5, possesses so-called screening slats 18 which face towards the side where the rays of the sun impinge, these screening slats 18 being arranged in spaced relationship from one another and in substantial parallelism.
- slats I8 directed towards the sun ray impinging side is intended to convey the concept that the edges of the slats l8 confronting the inside area or room with which the shutter 12 is employed are located at a greater height or elevation than those edges facing towards the outside.
- the screening slats 18 arranged in spaced relationship from one another are interconnected by means of pairs of guides or guide links 20, and specifically such that the lower edge, that is to say, the edge of a screening slat 18 facing the outside is connected with an edge of the next successive lower situated screening slat, and which last-mentioned edge faces the inside area.
- the free spaces between the individual screening slats 18 are each covered by a respective regulating or control slat 22, the significance of which will be discussed more fully hereinafter.
- the lengthwise extending edges of the screening slats 18 facing towards the outside are hingedly connected with the guides 20 by hinge or pivot bolts 24.
- the lengthwise extending edges of the screening slats 18 facing towards the inside area are hingedly connected or articulated with the guides 20 by the hinge or pivot bolts 26.
- a so-called collecting rail 28 having a catch or receiving trough 30.
- each of the individual guide rails 16a of the guide rail means 116 is provided with two separate channels or grooves, that is to say, a guide groove or channel 3 3 with the guide sur face 31 and a further guiding groove or channel 36, also referred to herein as a control channel or groove 36.
- the grooves 34 and 36 are arranged at lateral spacing from one another.
- bracket-like bearing surfaces 38 merging with the control or guiding groove 36, and considered in the lengthwise direction of the guide rail arrangement 16, are a number of bracket-like bearing surfaces 38 arranged in spaced relationship from one another.
- the guide rail arrangement 16 is here disposed such that the bearing surfaces or supports 38 are directed towards the inside area. If for some reason, for instance because of space requirements, it is necessary to carry out a change in the rail arrangement, then it would be possible to also have the bearing surfaces or supports 38 directed, for instance, towards the outside.
- the hinges or pivot joints 24 equipped with guide bolts 40, which can extend past the ends of the individual slats and thus extend into the region of the associated guide groove or channel 34 and, on the other hand, the hinges or pivot pins 26 are provided with the latch or stop pins 44 which, in turn, cooperate with the supports or bearing surfaces 38 of the associated guide rail 16a of the guide rail means or arrangement 16.
- each guide groove or channel 34 is constructed such that it extends past the lateral ends of the slats 18 in the direction of the opening which is to be covered by the shutter proper, as best seen by referring to FIG. 4. Due to this construction of the legs 35 there is realized an optimum lightand visual closure between the guide rail arrangement 16 and the foldable shutter 12.
- FIGS. 4a, 4b, 4c and 4d there is shown both a further exemplary embodiment of the guide rail arrangement 16 depicted in FIG. 4 as well as a further variant of the bearing surface or support 38 depicted in FIG. 4.
- a guide rail arrangement or guide rail means which cooperates with a guide system 122.
- the foldable slats 124 of the shutter are operatively connected with this guide system 122.
- the guide rail arrangement 120 possesses at each end of the slats a guide groove or channel 126 and a control channel or further guide groove or channel 128. At the guide rail arrangement 120 there is located a still further guide groove or channel 130 which faces away from the aforementioned channels or grooves 126 and 128.
- the end portions 132 of the legs 132' forming this U-shaped guide groove 130 are flexed or bent towards one another in such a way that between these confronting ends there is formed a slot-shaped opening 134 which is open throughout the entire length of the associated guide groove 130.
- a toothed rail or rack 138 Secured to the leg 136 of the control or guiding groove 128 is a toothed rail or rack 138 which cooperates with stop or latch pins 140 arranged at the borders or flanges 123 of the associated foldable slats 124.
- Each pin 140 possesses an extension 142 at which there is rotatably mounted a respective guide or guide link 144 and a connection arm 145.
- Each of the guide 144 as well as the connection arm 145 is provided at its free end with a respective further pin 146.
- This pin 146 furthermore carries at its axial end guide rollers 148 which cooperate with guide surfaces 131 of the guide channel or groove 130.
- Both the rack 138 as well as also the periphery of the stop of locking pin 140 are provided with sawtooth-like constructed locking or engaging teeth 152 and 154 respectively.
- the teeth 152 of the rack 138 as well as those, namely the teeth 154, of the stop or locking pin 140 are constructed such that they can mesh with one another.
- FIG. 6 the centerline symmetrically constructed foldable shutter or Venetian blind arrangement is shown in front view.
- the regulating or control band 46 and a drawband 48 for the foldable shutter 10 are located at each end of the shutter.
- FIGS. 1, 5 and 6 the foldable shutter 10 has been depicted in its lowered or let-down position.
- the screening slats 18 and the regulating or control slats 22 cooperate with one another in such a way that there is interrupted any passage of light from the outside into the inside area.
- actuating in other words by specifically drawing-up or pulling upon a regulating or control band 46 the regulating slats 22, which are connected via hinge connection elements 47 with the regulating band 46 (FIGS. 1, 2, 3, 5) are rotated about the hinge or pivot pins 24, so that, depending upon the degree of opening, they allow for a greater or lesser passage of light and air through the shutter 12.
- each drawband 48 which is mounted in the associated lateral guide groove 36 of the guide rail means 16, entrained by the shutter drive 14.
- Each drawband 48 is connected with its associated pin 42 which, in turn, are fixedly secured to the collecting rail 28.
- the lowermost screening slat 18 of the foldable shutter 12 together with the stop or locking pins 44 is displaced out of the support or bearing surface 38.
- This screening slat 18 is now displaced into a position parallel to the lowermost guide link or connection web 20 of the foldable shutter 12 and finally bears at the inclined portion of the collecting rail 28.
- the catch or receiving groove 30 of the collecting rail 28 prevents any lateral displacement of the gathered-up screening slats 18.
- the collecting rail 28 is drawnup for such length of time until all of the screening slats 18 as well as all of the regulating or control slats 22 are gathered-up beneath the drive 14 and collected together in the form of a package of slats, as best seen by referring to FIG. 2.
- the drive 14 will be rotated in the counterclockwise direction. In so doing, there is lowered each drawband 48 together with the therewith connected collecting rail 28. At the same time there is lowered the entire package or set of screening slats 18 as well as the regulating slats 22.
- the uppermost screening slat 18 is connected by means of its lengthwise edge confronting the inside area, via a suspension band 50, with the housing of the drive 14. As soon as the package composed of the screening slats 18 and the regulating slats 22 lowers, then the edge of the uppermost screening slat 18 confronting the inner area is held backby the suspension band 50.
- the length of the suspension band 50 is selected such that the hinge 26 and together therewith the stop or looking pins 40 comes to bear exactly at the uppermost support or bearing surfaces 38 of the guide rail means 16. This operation is assisted by the hinge or pivot joint 24 of the uppermost screening slat 18 in that the guide bolts 40 commonly mounted at the hinge 24, during lowering movement in the associated guide groove 34, draws the associated stop or locking pin 44 against the outer wall of the associated control or guiding groove or channel 36. Since the spacing between two supports or bearing surfaces 38, in the lengthwise direction of the guide rail means 16, is chosen such that the width x of the screening slats 18 and the length y of the guides 20 (see FIG.
- the aforementioned weight or ballast 32 at the lowermost regulating slat. It is of course also possible, instead of using a weight 32, to provide a non-illustrated tension spring which, for instance, connects the lowermost regulating slat 22 with the collecting rail 28.
- FIG. 7 there is illustrated in cross-sectional view a particularly advantageous constructional embodiment of foldable shutter 12.
- the basic idea of the configuration for the different components of the foldable shutter 12 resides in the fact that the individual elements in the folded condition can be stacked within one another within the smallest possible space. For this purpose it is necessary to maintain the leg length a both of the screening slats 18 as well as also the guides 20 and the regulating slats 22 to be the same length. Also for this purpose it is necessary to maintain the leg length b of these three components or elements of the shutter 12 so as to be the same. According to a further constructional feature there is to be ensured that the angle a formed by the legs a and b for each of these three elements 18, 20, 22 is of the same magnitude.
- FIGS. 8 and 9 there is designated by reference character 52 a cover plate.
- the screening slats 18 as well as the regulating slats 22, at one-half of their width with additional drawbands or support cords 58, so as to prevent any undesired throughbending of the individual components or elements.
- the screening slats 18 as well as the regulating slats 22 with the openings 60 so that bands or cords 58 which are necessary for supporting these slats can be drawn through the components of the shutter.
- each cover plate 52 will be understood to consist of, by way of example, two disks 54 and 56 arranged to both sides of, for instance, an associated screening slat 18 or regulating slat 22. These disks or plates 54, 56 cover an opening 60 which is provided for the purpose of permitting throughpassage of a cord 58 or the like for instance.
- the two disks or plates 54 and 56 of the cover plate 52 are connected with one another by an intermediate web 62.
- This web 62 is designed such that, viewed in the lengthwise direction of the individual slats, it fits practically without play into the opening 60, perpendicular to the lengthwise direction of the slats however can laterally displace, so that in this way there can be accommodated displacement of the cord 58 with respect to the screening slats 18.
- the disks 54 and 56 as well as the web 62 possess an opening 53 intended to permit the throughpassage or threading therethrough of the cord 58.
- the shield or armour construction formed by the slats forms a unit, that is to say, the indivdual slats are connected in a force-locking or positive fashion with one another.
- the slat shield In order to retain such slat shield in desired position it is mounted in the guide rail means 16 of the invention.
- this shield forms a unit the slats 18 subjected to the rays of the sun are either connected with one another by guides 20 or with such guides 20 by means of further slats which in cross-section coincide with these guides. This is necessary in order that the individual slats, when they are gathered-up or when the slat shield is lowered or letdown, mutually displace in the desired position.
- the slats 124 cooperate as follows with the guide system 122 in the guide rail means or arrangement 128: during drawing-up or lowering of the slats 124 the drawband 48 together with the collecting rail 28, (as such has also been depicted in FIG. 4 by position 48) will be correspondingly moved in the control or further guiding groove 128. Upon actuating the drawband 48 the collecting rail 28 will be correspondingly raised or lowered. At the collecting rail 28 there is secured the last screening slat 124.
- the screening slat 124 (FIG. 4a) is connected via the stop or locking pins as well as its extensions 142 with the guide system 122 and its guides 144 and connection arms 1415.
- FIGS. 4c and 4d of the bearing surface or support 138 possesses the advantage, in contrast to the bearing surface or support 38 depicted in FIGS. 1, 2, 3 and 4, that manufacturing inaccuracies in the folding system can be better compensated.
- FIG. 14 New in FIG. there is shown in sectional view the shutter drive 14, as the same can be advantageously constructed for actuating the foldable shutter or Venetian blind 12.
- reference numeral 64 designates a shaft which cooperates with a transmission or gearing drive 66.
- the transmission 66 can be manually driven or by means of a suitable motor viaa drive shaft 68.
- a hub 70 is seated upon the shaft 64, this hub 70 being rigidly connected for rotation with the shaft 64 by means of a wedge or key 72 or equivalent.
- keyways or grooves 78, 80 and 82 which correspond to one another.
- a key or wedge 83 over which, at the region of the drum 74, there is arranged a second key or wedge 84.
- the key 84 is provided with a nose-shaped raised portion 86, the significance of which will be considered hereinafter.
- a bolt 92 At the flank or end face of the drum 76 which confronts the drum 74 there is arranged a bolt 92, the function of which will also be discussed shortly.
- the drum 74 is provided for the purpose of receiving a drawband 48 or the like; the drum 76 in turn is intended for winding-up a regulating band 46.
- the shaft 64 Upon actuation of the drive 14 the shaft 64 is placed into appropriate rotational movement by operating the drive shaft 68 and also through the action of the transmission 66. As a result, the hub 70 keyed with the shaft 64 is entrained. Now if the foldable shutter or Venetian blind 12 is opened, that is, the drawbands 48 wound onto the drum 74, then these drawbands 48 press the key 84 into the keyway 82, the key 84 then bearing upon the key 83, and such then disappears into the keyway 78. Consequently, the drum 74 is placed in rigid rotational connection with the hub 70, whereas the drum 76 is loosely located upon the hub 70, and therefore, does not follow the rotational movement of the hub 70.
- FIGS. 11 to 14 this operation has been depicted in greater detail.
- the drawbands 48 wound upon the drum 74 press the keys or wedges 84 and 83 into the keyways or wedge grooves 78, 82 in such a way that between the hub 70 and the drum 74 there prevails a rigid rotational connection.
- a foldable shutter comprising slats, means for hingedly connecting the slats with one another, said slats having operatively associated with each of their respective opposed ends a respective guide bolt, guide rail means having guide surface means with which cooperate said guide bolts, said guide rail means further incorporating control channel means extending substantially parallel to the associated guide surface means of the guide rail means and in which there is guided an associated end portion of the shutter, a drawband for the shutter, support means provided for said guide rail means, each end of the slats carrying a stop pin arranged in substantially parallelly offset relationship with respect to the associated guide bolt and cooperating with said support means provided for the guide rail means, the spacing of the support means from the guide surface means of the guide rail means being smaller than the spacing between the guide bolts and the stop pins and wherein the control channel means extends between the guide surface means and the support means.
- control channel means has a leg portion and said support means are arranged at a substantially uniformly spaced distance from one another at said leg portion of the control channel means.
- the support means include spacer bands which connect the stop pins of neighboring slats with one another.
- each end of the slats possesses a connection arm at the free end of which there engages one of the guides.
- each connection arm is arranged at an end of the associated slat and pivotably connected therewith.
- connection arm is arranged approximately in the plane of the associated slat and rigidly connected therewith.
- each drawband and regulating band is disposed to operate in opposed relationship with regard to one another at the drum means and means for alternately rigidly drivingly connecting such bands with the rotational shaft of the drive.
