  • Patent number: 4896713
    Abstract: Drive unit for a vertical blind or the like, where the slats of the vertial blinds can be moved by an endless pull element, such as a pull chain. The drive unit has a housing (5) formed, for example, of plastic, an electric drive motor (6) placed in the housing (5), and a drive pinion or the like coupled to the drive motor, optionally by an inserted reduction gear. By enclosing of the drive components within the housing, a safe and unobtrusive drive unit is created. Preferred embodiments of the unit are constructed to enable the pull element to enter the housing through openings therein and be hung on the drive pinion. By this construction and the provision of control switches on the housing for operation of the electric drive motor, the drive unit is inexpensive and able to be retrofitted simply and versatily. Additionally, in an emergency, easy hand operation of the vertical blinds is still possible.
