Definitions

• the invention relates to a door according to the preamble of patent claim 1.
• Such doors are used for closing garages, halls, passageways, and the like.
• the door leaf can comprise a plurality of door leaf elements arranged one behind the other in the direction of door leaf movement and connected to one another in an articulated manner with respect to hinge axes running perpendicular to the direction of door leaf movement. In these cases, the door is referred to as a sectional door.
• Such sectional doors can be used to close building openings and passageways of considerable dimensions, i.e., a height of 3 m or more and/or a width of 4 m or more. Such door leaves are quite heavy.
• the motorized drive units for such doors are typically coupled to the door leaf via a reduction gear.
• the corresponding drive train of the motorized gear comprises an output shaft of the motor, in particular an electric motor, which is coupled to a drive shaft of the reduction gear.
• the output shaft of the reduction gear can be connected in a rotationally fixed manner to a cable drum, onto which a traction mechanism, coupled to a lower edge of the door leaf in the closed position, can be wound during the opening movement of the door leaf.
• a weight compensation device for example, comprising a torsion spring
• the torsion spring axis can run approximately parallel to the cable drum axis, and the cable drum can be connected to a torsion spring shaft for rotational stability.
• known gates For emergency operation in the event of a defect in the motor drive unit and/or a power failure, known gates have a manually operated drive unit that can be coupled to the gate leaf.
• This manual drive unit typically comprises a chain wheel that can be coupled to the drive shaft of the reduction gear, which is encircled by a hand chain.
• the motor drive unit is uncoupled from the drive shaft of the reduction gear, and the chain wheel is coupled to this drive shaft of the reduction gear.
• the chain wheel can then be turned manually by pulling on the hand chain that encircles it, thus effecting emergency operation of the gate.
• emergency operation does not actually guarantee the required properties, particularly with regard to the desired door running speed.
• a gate according to the preamble of patent claim 1 is in US 4560046
• the object of the invention is to provide a door with which the desired properties can be guaranteed even in emergency operation.
• the emergency drive train of doors has a traction means rotating around a deflection means, preferably arranged overhead. A pulling movement downwards is thus converted into a The lifting movement is deflected upwards.
• the deflection means can comprise a chain wheel or chain pinion.
• the traction means can comprise a hand chain.
• the invention provides that the traction means can be detachably coupled to the door leaf via a suitable coupling device only for emergency operation, while it remains unused and immobile during normal operation.
• the coupling device comprises a driver device that is detachably connected to the traction means, preferably via a suitable connecting device, in particular a snap hook.
• the coupling device comprises a holder attached to the door leaf, to which the driver device can be coupled, in particular in a form-fitting manner.
• a form-fitting coupling of the driver device to the holder is expediently secured.
• the coupling device can comprise a securing device operable to secure the coupling of the driver device to the holder.
• the driver device has a U-profile with two outer legs connected to one another via a connecting leg and running approximately parallel to one another
• the holder comprises a U-profile with two outer legs connected to one another via a connecting leg and running approximately parallel to one another
• the outer legs of the holder preferably run approximately in a horizontal plane in the closed position and the outer legs of the driver (holder) preferably overlap the outer legs of the holder after coupling to the holder (driver). This ensures a flat force transmission from the driver device to the holder.
• a stationary safety holder can be provided, to which the driver can be coupled during normal operation.
• the driver device can be secured to the safety holder using the safety bolt.
• the safety holder can, for example, be attached to a lateral frame member of the door leaf, which can have guide rails on its side facing away from the safety holder to guide the door leaf movement.
• these guide rails can have a vertical guide rail section that runs approximately parallel to the lateral edges of the door leaf when the door leaf is in the closed position.
• a horizontal guide rail section which, in the open position of the door leaf, runs approximately parallel to the side edges of the door leaf, and an arched section connecting the vertical section to the horizontal section.
• the safety holder and the driver device of a door according to the invention can be designed in such a way that the traction means, after coupling the driver device to the safety holder, is guided in a clearance between the driver and the safety holder, wherein the clearance can be designed approximately U-shaped so that the traction means can be easily inserted into the clearance.
• the invention can be used with particular advantage in sectional doors in which the door leaf has a plurality of door leaf elements arranged one behind the other in the direction of door leaf movement and articulated to one another with respect to hinge axes running perpendicular to the direction of door leaf movement, wherein the emergency drive train can be coupled to the lowest door leaf element in the closed position.
