Description

The invention relates to a hand-operated, mechanical drive device for exerting a direction-changing rotation of a drive wheel.

With the DE 39 36 912 A1 a hand-operated drive device for a shaft, in particular a drive shaft of a door leaf that can be moved overhead, has become known, which has a roller which is non-rotatably connected to the shaft or can be coupled to it and has a circumferential groove into which an endless roller enclosing a major portion of its circumference trained flexible strand is provided for the attack of a pulling hand, wherein the strand is inexpensive and easy to manufacture for a comfortable and safe manual operation at least in a jacket area of a correspondingly soft, flexible plastic.

The object of the invention is to create a hand-operated, mechanical drive device which makes it possible to be coupled with existing drive devices driven by an electric motor.

The object of the invention is achieved by the features of claim 1. The subclaims following the main claim relate to a further embodiment of the idea according to the invention.

The hand-operated, mechanical drive device for exerting a mutual rotation of a drive wheel essentially consists of a drive wheel that is mounted between two stationary bearings. So that the drive wheel can be driven, it has transmission attachments on both sides in the axial direction. These transmission approaches are used to ensure that a force can be exerted on drive trains by selectively actuating actuating elements. This is possible because an unlockable locking device can be arranged between the components of the drive trains and the transmission attachments. This locking device can be locked and opened in both directions of rotation by the application of force via the actuators. A rotational movement of the drive wheel that changes the direction of rotation is made possible by the respective actuated drive train through contact of transmission rollers with the transmission projections. At least one torsion spring is inserted in a bore that passes through both the transmission attachments and the drive wheel so that the drive trains are automatically returned after the force has been applied to the drive trains. This at least one torsion spring is connected at each end to winding devices of the drive trains. The winding devices form the space to wind up the existing ropes or tapes actuators. So that there is no malfunction when the drive device is actuated, the winding devices are essentially pot-shaped with a bottom. On the outside of the floor there are spiral guides, in which a guide element engages. The guide element is designed as a driver and is guided in an outer closure that surrounds the drive device.

In the case of the locking device, in a preferred embodiment, rotatable transmission rollers are mounted in carriers, which are in their rest position have no power transmission contact with the transmission lugs. In terms of drive, the carriers are crowned by the pot-like winding devices, with courses within the winding devices which include an approximately oblique course. The transmission rollers engage in these curves and can only come into such contact with the transmission attachments in the form of a freewheel when the drive elements are actuated, which thereby causes the transmission attachments to rotate. Such a construction ensures that only one of the two actuating members can exert a relative movement of the transfer lugs.

The drive wheel, which is mounted essentially centrally in the drive device, can be designed as a bevel gear with a driven wheel and a subsequent geared arrangement. At the output of the gear assembly there is the possibility of connecting, either directly or indirectly, rotary motion of the hand-operated drive device to external assemblies or devices of any kind capable of being connected to the drive device. This can be, for example, external worm gears or an electrical drive device that has been switched off. Due to the construction of the external device, individual usability of the drive device according to the invention is possible, with the external device also being able to fulfill only the formation of a mechanical braking device.

With the drive device presented, it is possible, for example, to carry out an emergency operation on automated gates that are connected to an electromechanical drive device. It is also possible in a preferred embodiment that one end of the armature of the electric motor is connected to the geared arrangement of the mechanical drive device. It goes without saying that the electric motor is or is de-energized.

With such a combination, consisting of a manually operated mechanical drive device and an electric motor drive device, door leaves or other devices can be easily moved both during repair work and in the event of power failures.

the figure 1 shows a possible embodiment of a hand-operated, mechanical drive device 1. The drive device 1 has an outer closure 2, in which the entire drive mechanism is accommodated and also partially stored. Since the drive device 1 does not require external energy, an optional left or right actuation of a driven gear wheel 27 can be carried out via actuating members 3, 4, for example in connection with a bore 35. The actuators 3, 4 have been shown in this preferred embodiment as foils or tapes, which can be wound onto winding devices 5, 6.

If you remove the outer conclusion 2, it can, according to the figure 2 , a possible embodiment of the drive device 1 are considered in a perspective view. The basic structure of the drive device 1 consists of a drive wheel 14 which is mounted laterally in bearing plates 7, 8 by means of bearings 34. The bearing plates 7, 8 are mounted in openings 12, 13 of the outer closure 2. To the side of the bearing plates 7, 8, the winding devices 5, 6 are visible. In this exemplary embodiment, the drive wheel 14 has been shown as a bevel gear which is in operative connection with a further bevel gear 19 which is offset by 90°. On a common axis of the bevel gear 19 there is a gear 18 which cooperates with a driven gear 27, these teeth representing a geared arrangement, such as those of figure 3 can be seen.

The winding devices 5, 6 are pot-like with a bottom in a preferred embodiment figure 6 been carried out, the bottom of the pot having a bore 30 which is mounted on one side on an axis 28 by means of a bearing. The free opening of the winding device 5, 6 is stored via the transmission rollers 23 of the locking device, as well as fixed or unlocked. In the bottom of the pot of the winding devices 5, 6 there is a spiral guide 15 on the outside incorporated. Guide pieces 10, which are guided in guides 9 within the outer closure 2, interact with the spiral guides 15. The design of the spiral guide 15 in connection with the guide piece 10 and the guide 9 makes it possible for the stroke of the actuating elements 3, 4 to be limited in terms of displacement. For safe guidance of the actuators 3, 4 guide rollers 17, 20 are present on both sides. These guide rollers 17, 20 are mounted in the bearing plates 7, 8 at one end and in the outer closure 2 at the other end. This basic structure described above can also be seen again from the side view of the figure 3 be removed.

In order to be able to exert a rotational movement on the drive wheel 14 via the actuating elements 3, 4, a carrier 22, which is part of the locking device 23, is rotatably mounted on each side of the drive wheel 14. In a preferred embodiment, after figure 4 has a driver 21 on the side directed towards the bottom of the winding device 5.6. This driver 21 engages in an opening 31 of the winding devices 5, 6 respectively. This ensures that when an actuating force is exerted via the actuating elements 3, 4, this is converted into a rotational movement of the carrier 22. Within the carrier 22, the transfer rollers 23 are mounted so that they with the overlying winding devices 5, 6 with courses 32 after figure 5 can work together. This interaction of the transfer rollers 23 and the courses 32 is dimensionally coordinated so that the attractive force via one of the actuating members 3, 4 forces the transfer rollers 23 to be pressed onto the respective transfer attachment 33 by means of the slopes in the courses 32. This forced pressing of the transfer rollers 23 onto the transfer lugs 33, which are fastened on both sides to the drive wheel 14, causes the drive wheel 14 to rotate. To support the pressure forces of the transfer rollers 23 on the transfer lugs 33, additional spring elements can also be used here.

The actuating path via the actuating members 3, 4 is limited by the spiral guide 15 in connection with the guide piece 10. If no further tensile force is applied to one of the actuating elements 3, 4, the drive wheel 14 will not rotate any further.

Due to at least one torsion spring 24, 25, 26, which is introduced by means of a bore in the transmission lugs 33 and the drive wheel 14, restoring forces can be generated because the ends of the torsion springs 24, 25, 26 are connected to the winding devices 5, 6, respectively. The arrangement of the torsion springs 24, 25, 26 within the unspecified bore of the transfer lugs 33 can the figure 7 be removed. This also makes it clear that the transfer rollers 23 can rest on the surfaces of the transfer lugs 33, as the figure 5 with the curves 32 can be seen.

The schematic representation after figure 8 makes it clear that by means of the output wheel 27 in conjunction with a suitable connection 37, an external device that meets the desired requirements can be easily connected, which is capable of other machines or machine devices or drives or gates that are not shown and not listed conclusively, purely mechanically drive on the application of muscle forces via the actuators 3, 4 in two directions of rotation.
