Sewing machine is held by a support frame at the sewing machine frame, with a lifting and swing movement through a cut opening in the table plate, to be positioned to give the maximum user comfort

摘要

The sewing machine has a frame (2) with a carrier frame (8) held by a guide mechanism (7), and moved up and down by a lifting drive (14). The carrier frame supports the sewing machine table plate (12), with a cut opening (13). The sewing machine carrier plate (19) has dimensions matching the cut opening in the table plate, and is moved by its guide mechanism (17). The sewing machine (31), with a needle plate (35) at the column (34) or free arm, is on the carrier plate. A further lifting drive (25) moves the carrier plate in an upper position where its upper surface is flush with the upper side of the table plate and a lower position where the upper side of the needle plate is flush with the table plate. The swing axis (18) of the carrier plate is parallel to the machine longitudinal axis. A cover plate shrouds the remainder of the opening when the sewing machine is in the lower position. The sewing machine has a cover plate at the table opening, with a separate removable plate insert against the needle plate. The carrier plate has a setting unit to determine the swing position The lifting drive has a motor (26) to move the carrier plate up and down. The cover plate is at a supporting protective frame on the carrier plate. The motor has two switches, in series, where only one is operated when the protective frame is in the working position, and the other is operated only when the carrier plate is in the start swing position. The carrier frame can swing together with the table plate around a horizontal axis, through a setting unit.
