FIELD: construction. ^ SUBSTANCE: invention relates to construction industry, mainly to doorframe designs. Side support of doorframe contains two opposite elements conjugated between each other by the third staggered element made of metal profile, and latch receptacles in locking mechanisms with the adjustable side stop. The receptacle of each locking mechanism latch is represented with a hole being located in the proper locking mechanism stage of the third side support element. The adjustable side stop corresponds to each hole for locking mechanism latch and is in the form of flat metal frame formed by the first and second element pairs being opposite to each other. The first element of the first pair is made with blade being bent to 170-183°. As a result, the round edge of flat frame is formed and chute is made. The chute width is 1.0-1.5 of the third side support element stage thickness. There are holes provided in the above stage for the locking mechanism latches. The second element of the same pair is slotted for threaded fastening element to fix the flat frame in the required position. The flat frame is installed right up to the inner surface of the previously mentioned stage of the third side support element. The curved section of blade is located in proper hole for latch and is wide enough to ensure sliding movement of the blade along the parallel upper and lower walls of the above latch hole when the flat frame position is changed. The straight part of the blade is located at the side corresponding to the outer surface of the above third side support element stage. ^ EFFECT: simplification of doorframe design and improvement of its quality. ^ 3 cl, 6 dwg |
