The motor axle driveend 18 according to the presented third embodiment comprises end spurs 19 protruding outwards from the motor axle driveend 18. The outwards protruding end spurs 19 are Sharp-V-type end spurs 19 and have narrow ends and sharply inclined spur slopes 191, 192. - Preferably 1% to 20%, more preferably 1% to 5%, and most preferably 1% to 2% of the surface area of the cross-section of the motor axle drive
end end lock slider 33 slide and engage between the end spurs of the motor axle driveend - The electromechanical motor lock according to present invention may also comprise a manual unlocking assembly, said manual unlocking assembly comprising a manually operated unlocking element arranged to push said
lock slider 33 to the unlocked position. Said manual unlocking assembly may be simply clamped to a side of thelock frame 31. - With the help of the electromechanical lock according to the present invention the installation, process of installing the lock directly on a modified motor unit is simplified and faster when compared to prior art solutions.
- With the help of the electromechanical lock according to the present invention, the maintenance of the sliding door system and of the electromechanical lock is easier. With the help of smaller cross-sectional dimensions, the electromechanical lock according to the present invention also has a much wider application range.
- With the help of the electromechanical lock according to the present invention, directly locking on the motor end the force that is exerted on the doorleaf and belt system may be reduced.
- It is to be understood that the above description and the accompanying Figures are only intended to teach the best way known to the inventors to make and use the invention. It will be apparent to a person skilled in the art that the inventive concept can be implemented in various ways. The above-described embodiments of the invention may thus be modified or varied, without departing from the invention, as appreciated by those skilled in the art in light of the above teachings. It is therefore to be understood that the invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims and their equivalents.
