Embroidery frame support device

Abstract

In an embroidery sewing machine, an embroidery frame support device for supporting a front end portion of an embroidery frame installed in a cantilevered manner includes: a base member that is a base for attaching the embroidery frame support device to the embroidery sewing machine, and a Y slide rail (support member) having a movable end that can move relatively with the base member. The embroidery frame support device supports a front end portion of the embroidery frame from a lower surface thereof through an X slide rail attached to a tip portion of the Y slide rail. The embroidery frame support device can be attached to the embroidery sewing machine by screwing a base member to a cylinder bed. The screwing of the base member to the cylinder bed can be carried out from the upper side of a sewing machine table.

1 . An embroidery frame support device for supporting a free end of an embroidery frame, movably supported in a cantilevered manner in an embroidery sewing machine, so as to follow the movement of the embroidery frame, the embroidery frame support device comprising.
 a base member fixedly attached to a predetermined portion of the embroidery sewing machine; and   a support member supported on the base member so as to be relatively movable with the base member and movably supporting the free end of the embroidery frame.   
   
   
       2 . The embroidery frame support device as claimed in  claim 1 , wherein the support member includes a Y slide mechanism constructed so as to be retractable in a Y direction to follow movement of the embroidery frame in the Y direction. 
   
   
       3 . The embroidery frame support device as claimed in  claim 1 , wherein the support member includes an X slide mechanism supporting the free end of the embroidery frame so as to be slidable in an X direction. 
   
   
       4 . The embroidery frame support device as claimed in  claim 2 , wherein the support member includes an X slide mechanism supporting the free end of the embroidery frame so as to be slidable in an X direction. 
   
   
       5 . The embroidery frame support device as claimed in  claim 4 , wherein the X slide mechanism includes first and second slide members each sliding in the X direction relatively with each other; the first slide member is coupled to the Y slide mechanism; the second slide member is coupled to the free end of the embroidery frame; and the embroidery frame can be separated from the embroidery frame support device along with the X slide mechanism by releasing the coupling between the first slide member and the Y slide mechanism.
