Abstract
An embroidery frame for a sewing machine with an embroidering function to hold workpiece cloth for execution of the embroidering function is disclosed. The embroidery frame includes a lower frame receiving a lower side of the cloth, an upper frame clamping the cloth in cooperation with the lower frame therebetween, and a clamping mechanism pressing the upper frame against the lower frame, thereby holding the upper frame. The clamping mechanism includes a coupling member coupling the upper frame to the lower frame so that the upper frame is vertically swingable between a holding position and an opening position, a locking mechanism locking the upper frame at the holding position, an unlocking mechanism unlocking the upper frame, and a frame-opening biasing member biasing the upper frame so that the upper frame is displaced to the opening position when unlocked by the unlocking mechanism.
