Description

[Detailed description of the invention] (Field of industrial application) This invention is an embroidery catch frame that can be quickly, accurately, firmly and stably supported and fixed to the embroidery body frame in multi-head or single-head embroidery machines, and can be easily removed. It is related to.

(Prior art) The embroidery frame in a conventionally known embroidery machine is made by fixing the base end of the outer frame made of synthetic resin to the outer frame rod of the embroidery body frame with screws, covering this with embroidery fabric, and then attaching it to the inner frame. Previously, the embroidery frame was used for press-in machine embroidery, but recently some methods have been adopted in which the embroidery frame is supported and fixed to the embroidery body frame using magnets. However, these conventional embroidery frames are difficult and time-consuming to support and fix to the embroidery body frame, and are extremely unstable.In particular, the fixing strength against twisting movements is poor, and they tend to shift easily, making it difficult to efficiently perform high-precision embroidery work. I can't hope to do it,
Further, there are drawbacks such as not being able to freely adapt to the size of the embroidery frame and easily damaging the embroidered product.

(Technical Issues) Therefore, this invention is capable of firmly and stably supporting and fixing the embroidery main body to the frame, quickly, accurately, and easily, and can also be freely adjusted to different sizes by replacing the sheet, with high precision. The technical challenge is to make embroidery work more efficient.

(Technical means) To explain this invention with reference to drawing examples, 2
1 is a catch frame in which a hook part 4 integral with a base plate part 3 forms a groove part 5 having corresponding inner protrusions 4a, 4a at the upper end, and the catch frame 2 is formed by connecting an outer frame rod of an embroidery body frame to 1, the base plate part 3 is superimposed on the base plate part 3, and is integrally attached by screwing a set screw 7 screwed into the nut part 6. As shown in FIGS. 3 and 4, 8 is a stopper made of plastic having external protrusions 9 on both sides of its lower end, and is integrally formed with a resilient piece 10 having a claw portion 11 at its tip. A screw 12 is screwed into the center of the upper surface of the stopper 8 with a seat plate 13 interposed therebetween. As shown in FIG.
is fitted into the groove 5 of the catch frame 2 as shown in FIG.
By screwing screws 12 onto the upper surface of a, the outer protruding strips 9 on both sides are movably fixed in the groove 5 so as to be securely fastened to the lower surfaces of the inner protruding strips 4a and 4a. Reference numeral 14 denotes a catch frame in which the upper frame 16 is pivotally connected to the lower frame 15 by hinge parts 29, 29 so as to be freely openable and closable. Two engaging grooves 23 are provided on each of the four sides of the lower frame 15, and a sheet 24 made of transparent or translucent plastic, for example, having an embroidery opening 25 can be clamped thereto. It's becoming like that. Further, a mounting plate 17 having a handle portion 21 is integrally formed on the opening/closing side upper frame lever of the upper frame 16. On the lower surface of the tip of the mounting plate 17, there is a projection fitter 18, which is provided with grooves 20 on both end surfaces, and a fitting gap 19 between it and the upper frame 16 rod.
It is integrally molded to form a The catch frame 14 is made of plastic or the like. The sheet 24 to be clamped and locked to the catch frame 14 is, for example, a sheet 24 having a large embroidery opening 25 as shown in FIG. An embroidery opening 28 having a desired size and shape may be arbitrarily cut out in 27. Note that 26 is an embroidery fabric attached to the sheet 24 and film 27 so as to block the embroidery openings 25 and 28. However, in this device, the catch frame 14 with the sheet 24 clamped thereon is removably fitted into the groove 5 in which the projection fitter 18 is engaged with the fitting gap 19, and at the same time Cut line 2
The claw portions 11 of the elastic pieces 10 of the left and right stoppers 8 are respectively engaged in and fixedly supported by the left and right stoppers 8.

(Effects) This invented embroidery catch frame has a lower frame 15 and an upper frame 16 that can clamp and lock a sheet 24 having an embroidery opening 25 and an upper frame 16 that can be opened and closed, and a mounting plate 17 that has a handle 21 of the upper frame 16. Since the catch frame 14 is constructed in such a manner that a fitting gap 19 is formed between the protrusion 18 and the rod of the upper frame 16, each of which is provided with a cut line 20 on both end faces, the embroidery opening 25 is The sheet 24 can be replaced with a different sheet 24 as needed and used by attaching and removably clamping and locking it, making it possible to handle embroidery ranges of all sizes and shapes, as well as achieving uniform embroidery finish and solving the diversification of embroidery. It has outstanding effects, such as being able to contribute to In addition, a pair of left and right stoppers 8 each having an integrated elastic piece 10 having a claw portion 11 at the tip are fixed in a variable position in the groove 5 of the catch frame 2 attached to the outer frame rod 1, and the catch frame 14 is The projection fitter 18 is removably fitted in a vertically fitting manner into the groove 5 in which the fitting gap 19 is engaged, and the cut strips 2 at both ends are fitted in a vertically fitting manner.
Since the claw portions 11 of the elastic pieces 10 of the left and right stoppers 8 are respectively engaged and fixedly supported by the left and right stoppers 8,
The support and fixation of the catch frame to the embroidery body frame is extremely strong, stable, quick, accurate and easy, and by setting the embroidery position accurately, high-precision embroidery work can be performed efficiently, contributing to an outstanding improvement in production efficiency. It has excellent effects such as contributing to labor saving in productivity.
