摘要

#CMT# #/CMT# The device has a door leaf with a upper part and a lower part (6) which is movable via a bevel cut from a pivot (1) towards an opening axle of a doorway along a height proportional to the inclination of place of installation. The parts are connected by two or four hinges (2) along the width of the door leaf, where the hinges are positioned on an external face of the door leaf. A caster (3) is welded to the base of each lower part, and a set of U-shaped clamps (4) permits to maintain the lower part, where the clamps are made of aluminum. #CMT#USE : #/CMT# Used for opening a doorway e.g. pedestrian gate and sliding door, towards interior, where the doorway is situated at an entrance. #CMT#ADVANTAGE : #/CMT# The device permits to open the doorway towards interior at the entrance with the inclination higher than 12 percentage in an easier manner, thus avoiding to open the doorway exterior towards the road. The hinges are positioned on external face of the door leaf, thus avoiding tilting of the lower part via the exterior, thus permitting to totally lift the lower part during opening of the doorway. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a door leaf. 1 : Pivot 3 : Caster 4 : Clamps 5 : Section 6 : Lower part 7 : Upper part.
