#CMT# #/CMT# The screw unit has a distance piece (10) with a resting collar (11) arranged in a spreading element (2) at a fitting unit. Retaining elements (12) are arranged at a front side of the element. A positioning cylinder (13) is arranged between the collar and a cone (3). A cylinder guide (14) with a clamping region (15) is arranged at a free end of the element, where the end is adjacent to the cone and an angle of elevation (alpha) to the cone lies between 35 degrees and 55 degrees. A clamping cylinder (16) is arranged in an expansion sleeve (8) between a spreading leg (7) and a threaded hole (6). #CMT#USE : #/CMT# Blind screw unit for a hollow chamber profile for a door or window for fastening a fitting unit e.g. door or window hinges, strap hinge and bracket pin, for fastening a glass clamping strip and/or constructing a balcony at a wall in a building. #CMT#ADVANTAGE : #/CMT# The screw unit can be produced in a technically simple and cost-effective manner, and attaches the fitting unit to the window or door frame in a simple manner with less effort and reduced assembling complexity. The screw unit remains functional in the profile even after a fastening screw is unscrewed from the unit and is reusable in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side sectional view of a blind screw unit for a hollow chamber profile. alpha : Angle of elevation 2 : Spreading element 3 : Cone 6 : Threaded hole 7 : Spreading leg 8 : Expansion sleeve 10 : Distance piece 11 : Resting collar 12 : Retaining elements 13 : Positioning cylinder 14 : Cylinder guide 15 : Clamping region 16 : Clamping cylinder. |
