Description

[Detailed explanation of the invention] This invention is based on the
In a rail-type embroidery device used in a sewing machine, the runner running on the rail is locked to the rail at a desired position. Regarding the stopper that made it possible.

When attempting to embroidery in a straight line with a rail-type embroidery device, it is difficult to operate the embroidery frame, which can move freely in any direction, so that it only moves in one direction. Even if this was done, the stitches tended to meander slightly, making it difficult to obtain a neat straight stitch.

On the other hand, when carrying the stabbing device, it is desirable to keep the entire device in a fixed state so that the stabbing frame, movable rail, etc. do not move accidentally. This also applies when the embroidery device is attached to the sewing machine, or when the rail is tilted while the embroidery device is attached, or when the entire device is tilted. This is because when the rail is tilted and the runner runs carelessly, damage may occur due to collision with needles, etc.

The present invention provides a stopper that allows the runner to be locked at a desired position, thereby allowing a fabric tensioning part such as an embroidery frame to move only along one rail or to be fixed. It is.

Embodiments of the present invention will be explained below with reference to the drawings.
The stabilizing device proposed in JP-A No. 58-144160 includes a fixed rail 1, a substantially U-shaped metal fitting 3 slidably supported on the rail, and holding pieces 4 on both sides of the metal fitting. The bifurcated leg pieces 5 are slidably inserted into the respective parts, and the refracting plate 8 is fastened to a desired height by the fasteners 7 that are fixed through the vertical grooves 6 of the leg pieces, and one side of the refracting plate 8. A main body 13 includes a movable rail 10 that is slidably supported on the section and is orthogonal to the fixed rail 1, and a mounting surface 12 that is fixed on the rail and on which a cloth covering section 11 and an original image are placed.
This shows an example in which a stopper, generally designated by number 18, is provided on a pricking device having a fixed copying needle 15 pointing toward the original image, and the stopper 18 is
As shown in detail in FIGS. 2 and 3, the left and right holding pieces 4 are supported by fitting protrusions 20 protruding from both side end surfaces into the notches 19, respectively. Preferably, it consists of a pair of attachment plates 22 provided in a fork shape, and a screw 25 that is loosely fitted into a circular hole 23 formed in the attachment plate 2 and screwed into the metal fitting 3 through the vertical groove 6. By tightening, the crimping element 21 is crimped against the side surface of the rail, thereby locking the metal fitting in a fixed state. In the above, instead of fitting the protrusion 20 into the notch 19 and supporting it, the protrusion 20 may be pivoted to the holding piece 4 and supported. On the other hand, when the screw 25 is loosened, the crimp 2
1, if the crimping on the side of the rail, that is, the locked state, is released, or if the attached plate 22 or the holder is swaying after release, the crimping element 21 will hit the side of the rail during the sewing operation, which will interfere with smooth running. There is a possibility that it will come. In order to solve this problem, it is desirable that when the screws are loosened, the attachment plate is biased in one direction, so that the crimping element is always maintained in a state separated from the side surface of the rail under normal conditions. 2 and 3, a hook portion 27 at the upper end is hung on the upper end portion of the attachment plate 22, and a leaf spring 28 with a bent lower portion is attached to the leg piece 5. What is interposed between the two is shown. By interposing such a leaf spring, the attached plate 22 is prevented from wobbling while running, and the crimping force of the crimping element against the rail side surface is increased when the screw is loosened against the spring pressure. , it can be fixed even more firmly.

As another means, the attachment plate is rotatably pivoted to the holding piece at its upper end, and a convex portion or a protrusion is provided in the intermediate portion of the attachment plate between the pivoting portion and the screw.
Under normal conditions, the crimping element is separated from the side of the rail by bringing the protrusion or ridge into contact with the metal fitting or leg piece, and when the screw is tightened, the crimper bends using its own elastic force as a fulcrum. Similarly to the above, the crimping element is firmly crimped to the side surface of the rail.

In this case, the structure is simpler than that described above because no leaf spring is involved. Note that the same effect as described above can be obtained even if the protrusion or protrusion is provided on one side of the metal fitting or leg instead of being provided on the attachment plate.

The above shows an example in which a stopper is provided on a metal fitting that slides on a fixed rail, or the movable rail 10
It is also possible to provide a stopper similar to that described above on the refracting plate 8 that slidably supports the refracting plate 8.

Further, the stopper according to the present invention can be similarly provided in other rail-type stitching devices other than those mentioned above.

According to the present invention, the runner can be locked and fixed at a desired location on the rail by tightening the screw, so that the main body, that is, the fabric upholstery section 11 can be moved only in the X-axis direction or in the Y-axis direction. It can be moved only in the axial direction, allowing for clean straight stitches, and it is convenient to carry because it prevents the parts inside the device from moving inadvertently.

Claims (1)

[Claims for Utility Model Registration] (1) In an embroidery device used in a sewing machine in which the movement of the X-component and Y-component of the fabric tensioning section is carried out along each longitudinal direction of a rail arranged orthogonally, It consists of an attached plate that has one end supported by a runner that freely engages with the rail and a rail crimping element provided at the other end, and is fixed to the runner by loosely fitting into a hole in the attached plate. A stopper that is adapted to press the crimping element onto the rail by tightening a screw, thereby locking the runner in a fixed state. (2) The stopper according to claim 1, wherein the crimping elements are provided in a pair or bifurcated. (3) The stopper according to claim 1, wherein means is provided between the auxiliary plate and the runner to keep the crimping element apart from the rail under normal conditions.
