<p>#CMT# #/CMT# The device has a motor reducer (310) and a reversible worm wheel. A drive pulley (330) is rotated by the motor reducer. A driven pulley is arranged along with the motor, and a cable is arranged with a loop formed between the drive pulley and the driven pulley. A tensioning device e.g. compression spring (351), is arranged for the loop between the drive pulley and the driven pulley. A master cable or wire rope is arranged to connect a stranded cable loop and a sliding opening. #CMT#USE : #/CMT# Device for displacement of a sliding opening in a door frame of a picture window according to opening-closing stroke in an apartment building or industrial building. #CMT#ADVANTAGE : #/CMT# The master cable is arranged to connect the stranded cable loop and the sliding opening, thus allowing displacement of the sliding opening in an easy manner. The device occupies less space, and does not reduce dimensions of luminous surface of the window. The device is operated with bare hands. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a motorized device with an opening fixed at an upright of a door frame. 310 : Motor reducer 330 : Drive pulley 351 : Compression spring 352 : Bolt 353 : Fastening unit.</p> |
