Abstract: A tool cabinet includes a cabinet body having two guide rails, a working platform unit having a movable platform member and two hollow extension members, two lifting units each having a threaded rod, two driving units, and a control unit. The extension members are respectively slidable relative to the guide rails. The threaded rods respectively extend through the extension members and telescopically into the guide tubes. Each driving unit has a motor, and a speed reduction mechanism driven to rotate the threaded rod of a respective lifting unit. The control unit is connected to the motors for synchronizing movements of the motors.
Abstract: A supporting mechanism is disclosed in the present invention. The supporting mechanism includes a base, a supporter, a latch and an actuating component. A hole and an accommodating structure are formed on a bottom of the base, and an opening of the accommodating structure faces outward of the base. The supporter is movably disposed inside the accommodating structure. The supporter includes a contacting pillar, which pierces through the hole and stretches into the base. The latch is slidably disposed inside the base. The latch includes a pushing portion for pressing the contacting pillar, so as to move the supporter out of the accommodating structure. The actuating component is pivotably disposed by a side of the base. The actuating component includes a handle and an actuating portion. The actuating portion can rotate toward an inner of the base for pushing the latch when the handle rotates outwardly.
Abstract: An auxiliary table for a sewing machine includes a table body formed into a flat plate shape and including one or more rectangular portions, the table body having corners, an upper surface at an upper side in a direction of gravitational force and an underside at a lower side in the direction of gravitational force, a cloth-receiving member disposed on at least one corner of the table body so as to be located lower than the upper surface of the table body and configured to support the workpiece cloth when it is placed on the upper surface side of the table body and hanging downward from the table body, the cloth-receiving member having a receiving portion having an outer edge surrounding outer edges of the corners, and a supporting member supporting the cloth-receiving member so protrusion of the cloth-receiving member from an outer edge of the table body is changeable.
Abstract: A sewing machine includes a sewing machine bed, an auxiliary table detachably attachable to the bed, a guide member guiding the table between a first position where the table is held in parallel to an upper surface of bed and a second position where the table is detachably attached to the bed, and an engaging member mounted on the table so as to engaging the guide member. The guide member and the engaging member are engaged with each other, so that a tilt of the table to the upper surface of bed is limited within a predetermined angular range when the table is positioned between the first and second positions. The guide member has a bearing portion and a side plate having a groove guiding the engaging member from the first to second positions. The engaging member has a sliding contact portion brought into sliding contact with the bearing portion.
Abstract: An auxiliary table for a sewing machine includes a table body formed into a flat plate shape in a planar view and including one or a plurality of rectangular portions, the table body having a plurality of corners, an upper surface at an upper side in a direction of gravitational force and an underside at a lower side in the direction of gravitational force, a cloth-receiving member which is disposed on at least one of the corners of the table body so as to be located lower than the upper surface of the table body and supports the workpiece cloth placed on the upper surface side of the table body and hanging downward from the table body, and a supporting member which supports the cloth-receiving member so that an amount of protrusion of the cloth-receiving member from an outer edge of the table body is changeable.
Abstract: A sewing machine includes a sewing machine bed, a flat-plate-shaped auxiliary table detachably attachable to the sewing machine bed, a guide member mounted on the bed and guiding the auxiliary table between a first position set at a rear side of the bed and where the auxiliary table is held in parallel to an upper surface of the bed and a second position set at a front side of the bed and where the auxiliary table is attached to and detached from the bed, and an engaging member mounted on the auxiliary table so as to movably engage the guide member. The guide member and the engaging member are engaged with each other, so that the inclination of the auxiliary table relative to the upper surface of the bed is limited in a predetermined angle range when the auxiliary table is positioned between the first and second positions.
Abstract: A method of assembling a prosthetic valve using sheets of material, such as pericardium material, polymer or bioengineered film, or other material. The method provides an accurate and repeatable system of making pericardial valves in which sheets or pieces of material are held securely in place relative to each other throughout the steps of assembling the valve. In addition, methods of the present invention include maintaining consistent alignment of the fixtures and pericardium material throughout the valve assembly process and utilize features that make the tooling components easy to assemble and handle. Certain aspects of the invention can be used to help establish a repeatable sewing and cutting technique for creating a pattern shape for valve leaflets, establishing stitch lengths, and determining the exact placement of stitches.

Abstract: An apparatus for sewing stitch-group seam patterns of a longitudinal direction that runs lengthwise or crosswise of an edge of a work piece comprises a table with a slab with an operator's side allocated thereto. Disposed on the slab is a bearing plate with a sewing machine resting thereon by its base plate. The slab is pivotable by a right angle between a first and a second working position and about a pivot bearing with an axis that is perpendicular to the slab. In this way, the position of the sewing machine relative to the operator's side is modifiable by a right angle.
Abstract: A sewing machine for sewing large work pieces such as sails or tarps, has a sewing bed with a large trough, the axis of which is perpendicular to the axis of the sewing head support arm. Fabric is held within the trough, either by being folded, bunched or rolled, with fabric being either fed into the trough as stitching progresses, or is drawn out of the trough during stitching. The fabric may be rolled, bunched or folded within the trough. The trough may be selectively covered with a removable cover plate, to provide a flat sewing bed for sewing of smaller pieces of fabric.
Abstract: An apparatus is provided for supporting fabric placed in a frame attached to an embroidery machine to relieve the weight of the fabric and allow the embroidery frame to move under the embroidery needle, the apparatus including a pair of lightweight, slidable supports, one of each being positioned under each end of the fabric secured in the embroidery frame so as to slightly elevate and support the fabric above the plane of the embroidery frame. The supports preferably are hollow and round having a flat top wall and a bottom wall. Each top wall includes a strap to secure fabric to the support. The bottom wall is smooth and flat and slides easily on a support surface. In one preferred embodiment, the top wall of the support is removable, allowing the inner chamber of the support to be used for storage of lightweight materials. The device also can employ only one support if appropriate.
