Definitions
- the invention relates to a device for driving a plurality of shafts of a lamellar system with bidirectionally rotatable lamellae arranged in a plane in a bearing device, with a drive shaft for driving a first connecting rod which is connected to the plurality of shafts via a plurality of lever devices, the Lever means are each connected in their one end region to a first axis, which is rotatably supported in a bearing in the connecting rod, and is fixed in its other end region are connected to a shaft rotatably mounted in a bearing.
- Devices of the type mentioned at the outset are used in the prior art to rotate slat systems formed from a plurality of rows of rotatably mounted slats for regulating the amount of daylight entering the interior of a building from outside through a window front.
- the slats can have considerable dimensions of, for example, 0.5 m ⁇ 3 m and, depending on the material from which they are made, have a considerable weight.
- a drive device for driving the slats must be designed accordingly robust.
- the drive devices known in the prior art for operating lamella systems can be divided into two subcategories.
- a first subcategory the slats can be rotated bidirectionally by a predetermined angle, but in practice this angle is always smaller than 170 °.
- the reason for this is that, due to a corresponding angular function, the power arm decreases rapidly at angles greater than 90 °, so that the force required to drive the lamella shafts increases rapidly at angles greater than 90 °.
- the drive systems in this subcategory therefore have the disadvantage that an endless bidirectional rotation of the slats as often as desired through 360 ° forwards and backwards is not possible.
- the shafts on which the lamellas are mounted are operated with the aid of chains and sprockets.
- the drive systems of this subcategory have the advantage that the shafts are infinitely drivable bidirectionally.
- lubrication is necessary for the chains, the lubricants causing contamination and maintenance-intensive relubrication, and moreover each chain has a play that must be compensated for by chain tensioners, whereby in addition, after a long period of operation, chain stretching occurs, which must be compensated for by safe chain operation by retensioning the chain.
- the drive devices of the second sub-category are susceptible to failure and are accordingly maintenance-intensive.
- Another disadvantage of the devices of this subcategory is that the distance at which the lamella shafts to be driven are arranged cannot be continuously changed continuously.
- the object of the invention is to provide a device for driving a plurality of shafts of a lamella system which are arranged in one plane in a bearing device, which is simple, robust and inexpensive and is correspondingly low-maintenance and thereby enables bidirectionally endless drive of the lamella shafts of a lamella system.
- this object is achieved according to a first aspect of the invention in that at least one further connecting rod is provided, the lever device of which is at a fixed, predetermined angle to the lever devices of the first connecting rod.
- this object is achieved according to a second aspect of the invention in that a second connecting rod with a plurality of second lever devices is spatially separated from the first connecting rod provided with a plurality of first lever devices on the side opposite the first connecting rod Shafts of the lamella axes is arranged, the second lever device being connected in its one end region to a first axis which is rotatably mounted in each case in a bearing in the second connecting rod, and in its other end region in each case fixedly rotatable with one each in a further bearing mounted shaft are connected, and wherein the lever device of the first connecting rod are arranged at a predetermined angle to the lever devices of the second connecting rod.
- the respective combination of features ensures that the first connecting rod and the at least one further connecting rod together form a drive unit in which a force is exerted in the longitudinal axis of the First and further connecting rods mounted parallel to one another, regardless of the end position after the end of a previous drive operation of the lamella shafts, always have a sufficiently large force arm to prevent the lamella shafts from rotating to cause a clearly definable direction of rotation, so that a bidirectionally endless drive of the lamellar shafts of the lamellar system is guaranteed.
- the device according to the invention has the advantage that the material from which the connecting rods and lever device are made can be selected identically with the material from which the bearing device is selected. This ensures that these components have the same coefficient of expansion and thus tension is avoided.
- the device according to the invention in accordance with the first aspect, it is provided that only one further connecting rod is provided.
- the angle between the lever devices of the first and the second connecting rod is preferably dimensioned at 45 °. At an angle of 45 ° it is achieved that, regardless of the respective end position of the lever device after the end of a drive operation for changing the angular position of the lamella shafts when a new drive operation of the lamella shafts is started, there is always an optimal force arm for rotating the lamella shafts.
- the angle of 45 ° in the device according to the invention according to the first aspect corresponds to an angle of 90 ° between the lever devices of the first and second connecting rods in the solution according to the second aspect of the invention, because in the solution according to the first aspect the second end of a second lever device is connected to the second end of a first lever device and is therefore only indirectly connected to a shaft, and in the solution According to the second aspect, the second end of a second lever device is connected directly to a lamella shaft.
- the lever devices of the first connecting rod are formed in one piece with corresponding lever devices of the second connecting rod. This results in a particularly robust design of the corresponding lever devices and thus a high reliability of the device according to the invention.
- lever devices of the first connecting rod and the second connecting rod are formed in one piece, it is advantageous if the respective first axes of the lever devices of the first connecting rod and the respective second axes of the lever devices of the second connecting rod are formed by one axis in the first connecting rod.
- this results in particularly easy execution and mechanical manufacture of the respective lever devices, and on the other hand, lever devices designed in this way are particularly very robust and resilient.
- the device according to the invention can therefore be manufactured particularly cost-effectively and at the same time is designed to be particularly robust and resilient.
- Fig.l a preferred embodiment of the device according to the invention in cooperation with a lamella system, in a front view;
- FIG. 2 shows a section of the preferred embodiment of the invention shown in FIG. 1
- FIG. 3 shows the detail of the preferred embodiment of the device according to the invention shown in Figure 2 in a first side view; 4 shows the preferred embodiment of the device according to the invention shown in FIG. 3 in a second side view.
- the preferred embodiment of the device 100 according to the invention shown in FIG. 1 drives a lamella system of lamellae 10, 20, 30, 40 and 50 which are arranged on bidirectionally endlessly rotatable shafts 11, 21, 31, 41 and 51.
- the device 100 As shown in FIGS. 2 to 4, the device 100 according to the invention for driving the waves
- a drive shaft 130 for driving the plurality of shafts 11, 21, 31, 41 and 51.
- a first connecting rod 111 is in bearings via a plurality of lever devices 121, 121 'with the plurality of
- lever devices 121, 121 ' are each connected in their one end region to a first axis 123, 123', each of which is rotatably mounted in a bearing in the connecting rod 111, and to its other end region are each fixedly connected to a shaft 11, 21 which is rotatably mounted in a bearing 12, 22 in bearing device 101.
- a second connecting rod 110 is essential, the lever devices 120, 120 'of which are at a fixed angle of 45 ° to the lever devices 121, 121' of the first connecting rod 111.
- the lever devices 121, 121 'of the first connecting rod 111 are formed in one piece with corresponding lever devices 120, 120' of the second connecting rod 110.
- the respective first axes 123, 123 'of the lever devices 121, 121' of the first connecting rod 111 and the respective second axes 123, 123 'of the lever devices 120, 120' of the second connecting rod 110 in the first connecting rod 111 are each from an axis 123, 123 'are formed.
