FIELD: sewing engineering. ^ SUBSTANCE: table has frame with supports and pedals. Frame is composed of two lower U-shaped tubular members and two upper inverted U-shaped tubular members connected with each other by couplings allowing upper tubular members to be adjusted for fixing of table at predetermined height by means of notches at ends of upper tubular members. Upper tubular member planes are arranged at right angle to lower tubular member plane. Sides of frame are connected by means of tightening device. Pedals are disposed for displacement and fixing on tightening device. Supports are formed as square rubber bushings embracing lower U-shaped tubular members. Table top is composed of three parts. Metal substrate with rigidity ribs is attached from inside to central part of table top. Table has spring clamps arranged on inner side of table top for fixing the latter on frame. ^ EFFECT: simplified construction and manufacture process. ^ 2 cl, 11 dwg |
