Abstract

An attachment structure for detachably attaching a workpiece holder to a movable body used in embroidery stitching in a sewing machine. The movable body is movable in a horizontal plane in synchronism with a reciprocating motion of a sewing needle in order to move the workpiece relative to the needle. The workpiece is supported on the workpiece holder held by the movable body. The attachment structure includes pair of pins disposed at one of the workpiece holder and the movable body, pair of engaging grooves engageable with the pins and formed at remaining one of the movable body and the workpiece holder, projecting body disposed at one of the workpiece holder and the movable body, and resilient member engageable with the projecting body and disposed at remaining one of the movable body and the workpiece holder.

Dependent claims

An attachment structure in combination with a workpiece holder and a movable body for detachably attaching the workpiece holder to the movable body, the movable body being movable in a horizontal plane in synchronism with a reciprocating motion of a sewing needle in a sewing machine, the attachment structure comprising;

a first wall extending in a vertical direction and provided at one of the workpiece holder and the movable body, the first wall being formed with at least one engaging groove having U-shaped configuration;
a second wall extending in a vertical direction and provided at a remaining one of the movable body and the workpiece holder;
at least one engaging pin extending from the second wall, the at least one engaging pin being engageable with the at least one engaging groove in relative vertical sliding movement between the first and the second walls for preventing the workpiece holder from being moved in the horizontal plane;
a projecting member provided at one of the first and the second walls;
and
a resilient member provided at the remaining one of the second and the first walls, the resilient member having a guide portion engageable with the projecting member for preventing the workpiece holder from being moved in the vertical direction.
