ABSTRACT:
An embroidery frame, comprising a closed inner frame and an outer frame open at a point and a clamping device provided on the outer frame with one laterally projecting projection each at each of the two ends of the outer frame. A stud is provided that can be fixed at one projection and a screwing device is provided that cooperates with the stud and is supported at the other projection. The stud is displaceably guided within one projection at a closely spaced location from the outside of the frame and is supported with a head on a stop face of the projection. The other end of the stud is rigidly connected to a sliding block, which is longitudinally displaceably accommodated within a guide provided in the other projection. A tie rod is led out of the other projection extending obliquely toward the outside of the frame. The tie rod is pivotably arranged at the sliding block. The screw device is formed by a collet, which is arranged on the threaded section of the tie rod and is supported on a shoulder of the other projection. The shoulder extends essentially at right angles to the longitudinal axis of the said tie rod.
