| 20090013913 | Embroidery unit cover, side table for sewing machine, and sewing machine - An embroidery unit cover that covers an embroidery unit that is to be attached to a sewing machine for sewing embroidery that includes a planar portion that forms a substantially horizontal surface combined with a bed portion of the sewing machine and a free arm portion provided to the bed portion, a peripheral wall portion that runs continuously along a peripheral border of the planar portion and that extends vertically downward from the planar portion, and a first engagement portion that is disposed on the peripheral wall portion and that is structured to be attached to and detached from a second engagement portion disposed on at least one of the bed portion and the free arm portion. When the first engagement portion and the second engagement portion are engaged with each other, the embroidery unit cover forms a side table with the free arm portion. | 01-15-2009 |
| 20090199753 | Thread cutter for sewing machine - A thread cutter for a sewing machine includes a first thread seizing assembly which is reciprocally movable and has a distal end formed with a first thread seizing portion, the first thread seizing assembly seizing a needle thread passing a bobbin case and a bobbin thread by the first thread seizing portion, the needle thread passing the bobbin case, a cutting blade located at a position nearer to the needle hole than a movement locus of the first thread seizing assembly, a second thread seizing assembly seizing the needle and bobbin threads both seized by the first thread seizing assembly during a backward movement of reciprocation of the first thread seizing assembly, cutting the needle and bobbin threads in cooperation with the cutting blade. When moved backward, the first thread seizing assembly is swung so that the first thread seizing portion comes close to the second thread seizing assembly. | 08-13-2009 |
| 20090199754 | Thread cutter for sewing machine - A thread cutter for a sewing machine includes a first thread seizing assembly reciprocally movable and including two unit thread seizing members having distal ends formed with first thread seizing portions respectively, a cutting blade located nearer to the needle hole side than a movement locus of the first assembly, and a second thread seizing assembly seizing the needle and bobbin threads both seized by the first assembly during backward movement of the first assembly, cutting the threads in cooperation with the cutting blade. When the threads seized by the first assembly are further seized by the second assembly, the first assembly is moved so that the distal ends of the unit thread seizing members are spaced from each other by a predetermined distance in a direction intersecting a movement direction of the first assembly. | 08-13-2009 |
| 20100147989 | Thread winder and sewing machine provided therewith - A thread winder includes a thread winding shaft into which a bobbin shaft is inserted so that a bobbin is detachably attached to the thread winding shaft, a rotating mechanism rotating the thread winding shaft to wind a thread on the bobbin, a thread winding shaft switching mechanism switching the thread winding shaft between a preparatory position and a winding position, a guiding member guiding the thread from a thread spool to the bobbin, a guiding member position switching mechanism switching the guiding member between a guide position and a retreat position, and a link mechanism links both switching mechanisms so that the guiding member is located at the guide position when the thread winding shaft assumes the preparatory position and so that the guide member is located at the retreat position when the thread winding shaft assumes the winding position. | 06-17-2010 |
| 20100175601 | Needle plate and sewing machine provided therewith - A needle plate for a sewing machine includes a first needle plate fixed to a sewing machine bed and formed with a needle hole through which a needle passes and a rectangular hole through which a feed dog appears, a second needle plate disposed in front of the first needle plate and detachably attached to the first needle plate, an engagement mechanism sliding the second needle plate rearward from a front side of the first needle plate, thereby engaging the second needle plate with the first needle plate, and a disengagement operating member located on the second needle plate so as to operate the engagement mechanism so that the second needle plate is disengaged from the first needle plate. The disengagement operating member is moved frontward from a rear side of the first needle plate thereby to disengage the second needle plate from the first needle plate. | 07-15-2010 |
| 20100242819 | MULTI-NEEDLE SEWING MACHINE - A multi-needle sewing machine includes a machine frame side thread guide member fixed to a machine frame and having plural of machine frame side thread guide portions and guide threads drawn from plural thread spools located on a machine frame respectively, plural thread entrances defined in a needle bar case to introduce threads guided by the machine frame side thread guide portions to needle sides of needle bars, respectively, plural intermediate thread guide portions located between the machine frame side thread guide portions and the thread entrances so as to be movable respectively, the intermediate thread guide portions guiding intermediate portions of the threads, and a intermediate thread guide portion moving mechanism moving the intermediate thread guide portions according to movement of the needle bar case during movement of the thread entrances with movement of the needle bar case while the intermediate thread guide portions are spaced from each other. | 09-30-2010 |
| 20110011318 | SPOOL HOLDER AND SEWING MACHINE PROVIDED THEREWITH - A spool holder includes a spool holder base to which a plurality of thread spools is attachable, and a support base having a pivoting member. The spool holder base is a divided spool holder base and includes a first spool holder base having one end pivotally mounted on the pivoting member so that the first base is swingable, a second spool holder base continuous to the other end of the first base and a connection connecting the first and second bases. The divided spool holder base is switchable between a storage position where the spool holder bases are adjacent so as to be parallel to each other and a use position where the first base is swung about the pivoting member and the second base is swung so that the spool holder bases are spread so as to be nonparallel to each other. | 01-20-2011 |
| 20110011319 | Spool holder and sewing machine provided therewith - A spool holder includes a spool base and a thread guide mechanism including a thread guide member having thread guide portions guiding the threads extending from thread spools, respectively and a divided support pillar disposed so as to support the guide member on the spool base and including an upper support pillar having an upper end swingably mounted on the guide member and a lower support pillar having a lower end which is swingably mounted on the spool base, and a holding unit which holds the divided support pillar so that the pillar is switchable between a first position where both pillars are substantially vertically lined so that the guide member is located at an upper position in its use and a second position where both support pillars are bent at the connecting part so that the guide member is located at an accommodation position in its non-use. | 01-20-2011 |
