Description

The present invention relates to a folding shop and in particular a driven folding shop according to the features of the preamble of claim 1.

Many folding shops are known from the prior art, the flat store elements along their longitudinal sides are connected by hinges and the accordion-like can be brought from a closed position to an open position. In order to stabilize the movements when opening and closing, you have such folding store additionally provided with a holding structure in the manner of a Nuremberg scissors (also called pantograph). In this case, the holding structure may be arranged parallel to the longitudinal orientation of the planar loading elements, as for example in DE 1 683 176 A, or perpendicular to the longitudinal orientation of the flat loading elements such as in GB 901 247 B and GB 1 072 642 B.

The scissors-like support structure, as disclosed in the same way in GB 901 247 B and GB 1 072 642 B, is made of metal and essentially comprises a row of scissors halves of the same length, arranged one behind the other and crossing one another at a crossing point. The scissor halves are pivotally connected to one another at the point of intersection, the points of intersection lying in the longitudinal center of the scissor halves, so that the intersection points lie one behind the other on a straight line. The two ends of each scissor half are connected in end points pivotally connected to the ends of two other scissor halves. The crossing points of the support structure are connected via hinge pins with laterally movable in a rail conveyor elements and guided stable about this. The flat loading elements are connected in the middle of a first end face via a bolt either directly or indirectly via the conveying element with the crossing point of the support structure. In the fully closed position, the store elements are juxtaposed in a closing plane. The rail in which the conveying elements are movable, and the straight line on which move the points of intersection of the scissors-like holder, lie approximately in this Schliesbene. In the fully open position, however, the store elements are pivoted about 90 ° relative to the closed position and arranged in several approximately parallel planes one behind the other, so that they form a package flat close to each other store elements.

The difference between the scissors-folding shops from GB 901 247 B and GB 1 072 642 B is mainly that in GB 901 247 B the shop elements are connected to each other at their longitudinal sides by hinges, so that the respective first Store elements when opening by about + 90 ° and the respective second store elements when opening opposite by about -90 ° to be pivoted. In GB 1 072 642 B, on the other hand, the planar loading elements are not connected to one another by hinges along their longitudinal sides. Therefore, the shutter elements when opening or closing, all in the same direction, so for example all + 90 °, be pivoted. In GB 1 072 642 B, the loading elements are also pivotable independently of a lateral movement. For this purpose, the store elements are held in the middle of their first end side about a pivot pin about its central longitudinal axis pivotally in a conveying element. In the rail, in which the conveying elements are movable, a spindle is arranged, which cooperates with the pivot pin of the shutter elements and their central operation, all the shutter elements can be pivoted in the same direction. Furthermore, a cable is arranged in the rail, on which an outermost conveying element of an outermost loading element is fixed. With the help of the cable, it is possible to move the shutter elements from the closed position to an open position and back, whereby intermediate positions are possible. The scissors-like support structure ensures that when opening or closing at any time or at any intermediate position, despite the changing distance between the store elements all shop elements are always the same distance from each other.

In the two scissors-folding shops from GB 901 247 B and GB 1 072 642 B, the lateral trajectory of the crossing points of the scissors-like support structure and the conveying elements is located on a common line and in the plane of the closed shop elements. This means that in the open position, the store elements protrude on both sides beyond the level of the closed position. The distance to an opening or to a window to be closed or covered with such a folding shop, therefore, must be chosen the greater, the greater the lateral extent of the store elements of the folding shop. Under certain circumstances, however, the scope of an opening or a window frame is not wide enough for such a large-scale installation.

Although there are folding shops in which all shop items are pivoted away in the same direction of the closing plane when opening the store, so they have a smaller footprint for mounting and, for example, with a very small distance to a window arrange to be ordered. However, these folding shutters are not as stable in themselves as the scissors-fold shops described and also have a lower guide security when opening and closing. In addition, due to the longer effective lever arms, the problem of overcoming dead center is much more pronounced when the shutter elements are adjacent to one another in the closing plane. Separate efforts must therefore be made for automated opening in order to overcome the dead center, as is also documented in AT 502 827 B.

The object of the invention is to provide a driven folding store available, which is simple in construction and inexpensive to manufacture and avoids the disadvantages mentioned above.

In particular, the driven folding store should be stably guided open and closed, to be stable in itself and have a small footprint for the installation against the opening to be closed or covered level, so that he mounted, for example, with a small distance to a window can be. Next he should be able to operate automatically without a separate measure for the dead center overcoming.

This object is achieved by a novel folding shutter, as described in claim 1. The folder-loading has a first extreme loading element and at least one further loading element, which are driven from a closed position to an open position movable and back again. In this case, the store elements are stacked in the open position in a plurality of levels one behind the other and pivoted away in the same direction away from a closing plane. From this position they are movable to close in a common closing plane in which they are arranged rotated by about 80 ° -100 ° relative to the open position.

The shop elements have a geometric pivot axis which is arranged on the closing level and extends in the region of a first longitudinal side of the shop elements. In general, the store elements have two opposite end faces and two end faces interconnecting longitudinal sides. In this case, the pivot axis is also parallel to the first longitudinal side. Apart from the geometric pivot axis of the outermost store element, which may be fixed under certain circumstances in a fixing position, the geometric pivot axes of the other store elements are arranged displaceably on the closing plane.

Adjacent store elements are pivotally connected to each other by lever elements such that they are pivoted when opening or closing by angle with the same sign. The store elements with the lever elements form parallelograms whose angles change continuously when opening or closing.

The lever elements are articulated to articulation points of the store elements. In this case, the shop elements have three articulation points arranged at different intersections of the shop elements with virtual planes: first articulation points lie on a first virtual plane closest to the closing plane, outside articulation points on a virtual plane furthest away from the closing plane and center articulation points on a virtual plane between the both mentioned levels. All levels are parallel to the Schliessebene and both in the open position and in the closed position parallel and spaced from each other.

Such a trained folding shop has the advantage that no dead center situation occurs between the lever elements even in the closed position, so the levers are not arranged all shock on impact in a line. Even if the store elements are shock to shock in the closing plane and there is a dead center situation between them, the lever elements not caught in the dead center situation can automatically close the folding shutter without additional expenditures. However, the store elements do not necessarily have to be butt to shock in the closing level. Rather, the store elements can also be at a slight distance from each other in the closing plane or be arranged overlapping each other in the closing plane next to each other.

It should be noted that not all articulation points of a shop element, a lever element must be articulated. If a folding shop has only two shop elements, then in one of the shop elements, only lever elements are articulated to the first articulation point and the center articulation point and the adjacent shop element only to the center articulation point and the external articulation point.

It is understood that the inventive folding shutters are not limited to two store elements, but may have any number of store items.

In addition to the first articulation points, the Mittelanlenkpunkten and the Außenanlenkpunkten other groups of articulation points may be provided, each group of articulation points on its own level and the levels in the open position as well as in the closed position and in all positions between them parallel to each other and are spaced from each other. Further groups of articulation points can be useful, in particular, if the store elements are very wide or very heavy.

A fold-loading device according to the invention can be realized in a particularly simple manner if the first plane on which a group of first articulation points lies coincides with the closing plane and the first articulation points coincide in particular with the geometric pivot axes of the shutter elements. This simplifies the construction of the Falt-Laden as well as the movements and mechanics.

The easiest way to the lever elements in the region of the first end face of the store elements and / or in the region of the opposite second end faces to the store elements. Instead or with shop elements of great height, articulation points can also be provided with respect to the height on further levels, for example in the middle of the shop elements, wherein the shop elements then preferably have openings for the passage of lever elements.

In the region of the first end face, the store elements are held pivotable around their geometric pivot axis in conveying elements. The conveying elements themselves are movably mounted in a rail.

The rail, in turn, is advantageously in the closing plane. This is particularly advantageous when the first plane lies with the first articulation points in the closing plane and the articulation points coincide with the geometrical pivot axes. Then, if the rail is also in the closing plane, then a central pin, which is pivotally mounted in the closing plane or in a conveying element in the region of the rail, can pass through the loading element and a lever element in the first point of articulation of the loading element.

Otherwise, different bolts may be provided to connect the one hand, the loading element with the lever element and on the other hand to connect the shop element pivotally about the geometric pivot axis with the conveying element, wherein the pivot axis laterally displaceable by means of movable in the rail conveyor element in the closing plane is.

For particularly large or heavy store elements, it may be advantageous if the store elements of the folding store are also performed stable in the region of the second end face in a guide rail. This is useful even with increased demands on the reliability of the automated movement, for example, when the folding shop is difficult to access for maintenance. The store elements are advantageously held in holders, which are guided displaceably in the guide rail. The guide rail is usefully in a common plane with the rail. Again, it is structurally easiest if the store elements are held about their geometric pivot axes pivotable in the brackets.

As lever elements, in particular for the connection of the outermost store elements with an adjacent store element, advantageous two-point lever elements are provided. These two-point lever elements are then articulated on the outermost loading element in a middle articulation point and on the adjacent loading element either in a first articulation point which lies on a first plane closest to the plane or an external articulation point which lies on a plane which extends from the closing plane on farthest away. The center linkage point lies on a plane between the two mentioned.

For the pivotal connection of three store elements three-point lever elements (42) are provided. But an outermost store element and a store element adjacent to it can also be connected by means of a three-point lever element, in which case a free end which is not hinged to a store element remains on the three-point lever element. The free end may point towards the closing plane and then advantageously also be movably supported in the rail by means of a conveying element or else the free end points away from the closing plane.

Connects the three-point lever element three adjacent store elements together, so it is hinged to a first store element in a first pivot point, on a second shop element adjacent the second shop element in a Mittelanlenkpunkt and on the second shop element adjacent third shop element in a Außenanlenkpunkt , It is particularly advantageous if the outer articulation point lies diagonally opposite the first articulation point on the front side and the middle articulation point lies in the middle between the first articulation point and the second articulation point.

Particularly advantageously, the first pivot point is located on a virtual piercing point, in which the geometric pivot axis virtually pierces the first end face, the pivot axis preferably offset laterally offset from the center in the region of the first longitudinal side with respect to a defined thickness of the loading element and a center link point with respect to the thickness and a defined width of the loading element in the middle. The Außenanlenkpunkt is diagonally opposite the first point of articulation and therefore offset laterally from the middle.

The Falt-Laden is driven by a drive, which may for example consist of several synchronized motors, each of these motors is connected to a conveyor element and is particularly advantageously integrated into the conveyor element. A central control system ensures synchronization as well as opening / closing and stopping in an intermediate position. In such an embodiment, different fixing points for one or both outermost loading elements can be provided particularly advantageously for two outermost loading elements facing one another in the direction of the closing plane in the folding loading.

Another possibility for a drive forms a belt drive with a driven belt arranged in the rail, which is deflected in the end regions of the rail, and to which at least one conveying element is coupled. Preferably, a clamping device is provided for the coupling of the conveyor element to the belt, which can be configured as a separate component or integrated into the conveyor element.

In a further development of this folding-loading the first outermost store element is fixed in a fixation position, which is particularly advantageously provided in an end region of the rail. The second outermost loading element is connected to the driven conveying element coupled to the belt. Of course, instead of the second outermost loading element, another loading element may also be connected to a driven conveying element. It is also conceivable to hold another store element in a fixing position and to connect the two outermost store elements with a driven conveyor element, wherein the two driven conveyor elements then move in the opposite direction when opening or closing.

Further developments of the inventive folding-loading can be seen from the figures and the dependent claims.

The inventive folding shutter will be explained in more detail with reference to exemplary embodiments illustrated in the figures. In the figures, the same elements are identified by the same reference numerals. The explanations are given by way of example only and have no limiting effect. The figures are not true to scale and the proportionality of individual elements to each other is often not respected for better clarity. The figures show purely schematically: <Tb> FIG. 1a to 1c <SEP> with a view to a first end face, a first embodiment of a folding store according to the invention in various positions; <Tb> FIG. 2a to 2c <SEP> also with regard to the first end side, a second embodiment of a novel folding-loading in different positions; <Tb> FIG. 3a <SEP> in a perspective view, obliquely from the first end side, a further embodiment of the inventive folding tray in the open position; <Tb> FIG. 3b <SEP> in the same perspective view of the folding shutter of Figure 3a in the closed position. <Tb> FIG.

In FIGS. 1a to 1c, a first embodiment and in FIGS. 2a to 2c, a second embodiment of a folding store 10 according to the invention is shown. The two embodiments essentially differ in that the embodiment of FIGS. 1 a to 1 c has three store elements 12, but the embodiment of FIGS. 2 a to 2 c has five store elements 12, wherein the store element 12 shown on the far left in the figures is the first one Store element 12/44 and the shopper element 12 shown on the far right in the figures is referred to as the second extreme store element 12/46. All other store elements are referred to as further store elements 12. The folding shutters 10 are shown with a view of a first end face 14 of the store elements 12. 1a and 2a show the respective embodiment of the folding shop 10 in the open position O, in which the shop elements 12/44, 12 are arranged in several levels one behind the other as stacked in a package. As can be clearly seen, the shop elements 12/44, 12, 12/46 are arranged in this open position O with their first longitudinal side 18 in the region of a closing plane S and are each from this in the same direction approximately perpendicularly from the closing plane S. , so that in each case a second longitudinal side 20 is remote from the closing plane S.

A geometric pivot axis 22 of the store elements 12 extends in the region of the first longitudinal side 18 of the store elements 12/44, 12, 12/46 wherein the pivot axes 22 are also in the closing plane S. Moreover, if the first longitudinal sides 18 run at right angles to the first end faces 14, the pivot axes 22 also run parallel to the first longitudinal sides 18. When opening and closing the folding store 10 (see FIGS. 1b, 1c and 2b, 2c) geometric pivot axes 22 at least the other store elements 12 in the closing plane S moved.

The shop elements 12/44, 12, 12/46 are pivotally connected to each other at their first end face 14 via lever elements 40, 42, that they are pivoted when opening or closing by angle with the same sign. The store elements 12/44, 12, 12/46 in this case form with the lever elements 40, 42 parallelograms of variable angles, as can be clearly seen with reference to FIGS. 1a to 1c and 2a to 2c. The lever elements 40, 42 are articulated at articulation points 24, 26, 28 of the store elements 12/44, 12, 12/46. The articulation points 24, 26, 28 form three groups, each group of articulation points 24, 26, 28 lying on its own, parallel to the closing plane S level 1, 2, 3 and the levels 1, 2, 3 in the open position O (see 1a, 2a) as well as in the closed position G (see Fig. 2c) are arranged parallel and spaced from each other. As can be seen from the figures, the levels 1, 2, 3 are also in all intermediate positions (FIGS. 1b, 1c, 2b) parallel, spaced from each other.

The Schliessebene S closest is a first level 1, in the first pivot points 24 are located. In a more distant level 2 are center pivot points 26 and in one of the closing plane S furthest level 3 are Außenanlenkpunkte 28. It is understood that further groups of articulation points can be provided, if this due to the width extension and / or due to the weight of Store elements 12/44, 12, 12/46 makes sense. If further groups of articulation points are provided, four-point lever elements or lever elements of even higher order can be provided in addition to the two-point lever elements 40 and three-point lever elements 42.

As is apparent from FIGS. 1a to 1c and 2a to 2c, there is a further difference between the embodiments of the two figures in that in the first embodiment in Figs. 1a to 1c, the first plane 1 with the first pivot points 24th spaced from the closing plane S is provided. The first pivot points 24 and the pivot axes 22 are thus offset from one another. In the example shown here, the first articulation points 24 are further away from the closing plane. In order to realize the necessary lever element length, the Außenanlenkpunkte 28 must be relocated accordingly by means of cantilevers 29 on the second longitudinal side 20 of the store elements 12/44, 12, 12/46 out to the outside. The center pivot points 26 are located equidistant from the first pivot points 24 and the outer pivot points 28th

In contrast, falls in the second embodiment of Fig. 2a to 2c, the first level 1, on which the first pivot points 24, with the closing plane S together and the first pivot points 24 coincide with the pivot axes 22. As can be seen from the figures, here the outer anchor points 28 can be fixed without cantilevers on the front side 14. The center pivot points 26 are in turn arranged equidistant from the first articulation points 24 and the outer articulation points 28.

In both embodiments, the first outermost store element 12/44 is connected by a two-point lever member 40 with its adjacent store element 12, wherein the two-point lever member 40 at the outermost store element 12/44 in the middle pivot point 26 and the adjacent store element 12 in the first point of articulation 24 is articulated.

In the exemplary embodiment of FIGS. 1a to 1c, the second outermost store element 12/46 with its adjacent store element 12-which in this particular case is at the same time the adjacent store element 12 to the first outermost store element 12/44 -is likewise characterized by a two-point contact element. Lever element 40 pivotally connected. This two-point lever element 40 is again articulated on the second outermost loading element 12/46 in the middle articulation point 26, but on the adjacent loading element 12, on the outside articulation point 28. The store element 12 between the two outermost store elements 12/44, 12/46 in turn is additionally connected via a three-point lever element 42, which is articulated at its Mittelanlenkpunkt 26, with the two outermost store elements 12/44, 12/46. This three-point lever element 42 thus also connects the two outermost store elements 12/44, 12/46 with each other.

In contrast, in the second embodiment of FIGS. 2a to 2c, the second outermost store element 12/46 is connected via a three-point lever element 42 to its adjacent store element 12. The articulated in the second outer store element 12/46 in the center pivot point 26 three-point lever element 42 therefore has a pointing in the direction of the closing plane S free end 43. The other, between the two outermost store elements 12/44, 12/46 arranged store elements 12 are each connected to its two adjacent store elements by three-point lever elements 42.

FIGS. 3a, 3b and 3c show a third embodiment of the folding store 10 according to the invention; in Fig. 3a, 3b perspective view obliquely on the first end face 14 and in Fig. 3c with a view obliquely to the second end face 16. Fig. 3a shows the folding shutter 10 in the open position O, and Figs. 3b and 3c show it in the closed position G. The closing plane S is indicated in FIG. 3a by a frame. In the open position O, the store elements 12 are in turn arranged in several more or less parallel planes in a row behind one another. They are all oriented in the same direction away from the closing plane S. Compared to the closed position, in which the shop elements 12 are juxtaposed in this case in the closing plane S to shock, the store elements 12 in the open position by about 80 ° to 100 ° - in the ideal case by 90 ° - arranged twisted.

It should be noted here that, unlike for the second embodiment (Fig. 2c) and the third embodiment (Fig. 3b) shown, it is also conceivable that the shutter elements 12 in the closed position G not tight to shock adjacent to each other in the closing plane S next to each other, but are arranged with gaps or overlapping each other in the closing plane side by side.

The third embodiment is analogous to the second embodiment, except that instead of a total of five store elements 12 in this embodiment, a total of four store elements 12, namely a first extreme store element 12/44 and three other store elements 12, are provided, in the closing level S considered the first outermost store element 12/44 opposite loading element in turn is referred to as the second extreme store element 12/46.

The store elements 12 are in turn pivotally connected to each other at their first end face 14 via lever members 40, 42, wherein the first pivot points 24 coincide with the pivot axes 22 as in the second embodiment. As can be seen from FIG. 3 a, the first outermost store element 12/44 is pivotably connected to the adjacent store element 12 again by a two-point lever element 40. The other store elements 12, however, are connected to one another and also to the first outermost store element 12/44 and the second outward store element 12/46 by means of three-point lever elements 42, the outermost three-point lever element 42 having a free end 43.

The folding shop 10 according to the third embodiment can be automatically opened and closed via a drive A. In the area of the first end face 14 of the store elements 12, it has a rail 30 which lies in the closing plane S and is displaceably mounted in the conveying elements 32. The rail 30 is only indicated so that the conveying elements 32 can be seen. The first outermost loading element 12/44 is fixed in this example in the end region 31 of the rail 30 in a fixing position P.

In the conveying elements 32, the store elements 12 are pivotally mounted about their geometric pivot axis 22, for example by means of a bolt, not shown. Likewise, the free end 43 of the outermost three-point lever member 42 is pivotally connected to a conveyor element 32 for better power transmission and guidance. Also in the closing plane S - and thus in the same plane as the rail 30 - in this embodiment, in the region of the second end faces 16 of the shop elements 12 is a guide rail 36 (Fig. 3a). In the guide rail 36 brackets 38 (Fig. 3c) are slidably mounted, in which the shutter elements 12 are pivotally supported about its geometric pivot axis 22. In addition, 16 lever elements 40, 42 are articulated in this example also on the second end face. The configuration of two-point lever elements 40 and three-point lever elements 42 may be designed as on the first end face 14, or for example as on the first end face of the first embodiment (see Fig. 1a). The additional guidance on the second end face and the additional stabilization by further lever elements on the second end face always makes sense if the store elements have a corresponding size and / or a large weight, or if the store elements have no sufficient stability in themselves. Even with small and / or light store elements 12 such stabilization may be useful if a high reliability for the movement is to be ensured. In principle, however, it is also possible to configure the folding shutter 10 only with a rail 30 and conveying elements 32 movable therein.

Conveying elements and rails and guide rails and brackets for such purposes are known from the prior art, which is why a detailed description of the construction is omitted here. It should also be noted here that rail and guide rail need not necessarily be arranged in the closing plane, as long as it is ensured via the conveyor elements or brackets that the geometric pivot axes of the shutter elements lie in the closing plane.

In FIGS. 4a and 4b, an embodiment of a drive A for the inventive folding shutter 10 is shown. In FIG. 4 a, a section of the folding store 10 in the open position O is shown in a first end region 31 of the rail 30 and FIG. 4 b shows a section of the same folding store 10 in the closed position G in a second end region 31 of the rail 30. In the drive A shown here is a belt drive 60 with a belt 62 which is guided in the rail 30 circumferentially. The rail 30 is indicated here only with dashed lines, so that the belt 62 and the conveying elements 32, 32 can be seen. The belt drive 60 is arranged in this example in the first end region 31 of the rail 30, while a deflection roller 64 and a tensioning element 66 are arranged in the second end region 31 of the rail 30.

The first outermost loading element 12/44 is fixed in the first end region 31 of the rail 30 in a fixing position P. The second outermost store element 12/46 is connected to a three-point lever element 42 with the adjacent store element 12, the free end 43 is pivotally mounted in a driven conveyor element 32. The driven conveying element 32 is coupled by means of a clamping device 34 to the belt 62.

If the command to open the folding tray 10 is given, the belt is driven so that the run to which the driven conveyor element 32 is coupled, from its position in the open position O to the second end portion 31 of Rail is moved. By the pivotal connection, which consists by means of the lever members 40, 42 to the shop elements 12/44, 12, 12/46, the other conveying elements 32 are moved toward the second end portion 31 of the rail 30 and the folding shutter 10 opens , The store elements 12/44, 12, 12/46 form parallelograms with the lever elements 40, 42, the angles of which constantly change during opening.

Of course, instead of at the free end 43 of a three-point lever member 42, it is also possible to couple one or more other conveying elements by means of clamping device to the belt 62. Also, any other drives are possible as synchronized motors on all conveyor elements 32 or on only some conveyor elements and other more.

It is clear to the person skilled in the art that, and in which way, the described embodiments or the details described with reference to the exemplary embodiments can be meaningfully combined.
