Description

Embroidery Frame {An embroidery-frame}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an embroidery frame which can be supported by extending the length of a pizza blister.

When embroidering a pizza sachet by embroidery sewing, if the pizza sachet is a wide cloth such as fabric, the pizza sachet is placed on a rectangular embroidery frame driven to move in the XY direction on the table of the embroidery sewing machine. It is supposed to support the battlefield.

A projection is formed on the frame of the embroidery frame over the entire circumference of the inner circumference, and a support clip prepared separately for the projection is fitted to be detachably inserted. Then, after placing the pizza water in the state covered with the embroidery frame, a plurality of support clips are fitted on the pizza water at intervals required by the projections, thereby placing the pizza water on the embroidery frame over the entire circumference. I can support it in a state.

In the conventional support clip fitted to the projections in the embroidery frame described above, as the embroidery sewing proceeds to the pizza material fully supported on the embroidery frame, each support clip is pulled out of the projection due to the gradually increasing tension. There was a problem of throwing away at times. However, when increasing the supporting force of the support clip so that the support clip does not fall out of the projection, the attachment and detachment of the support clip to the projection becomes difficult, and it is pointed out a difficulty that the workability by the user is significantly reduced.

Therefore, the present applicant has proposed an improvement that can solve the above drawback, and has submitted a utility model registration application (Japanese Patent Laid-Open No. 6-59492) regarding the technology. However, according to the support clip in the present invention, although the support force for the projections can be increased, if the tension applied to the pizza water which is fully supported on the embroidery frame exceeds the limit, it may also fall out of the projections. Because of that, it was not yet complete.

The present invention has been proposed to improve the above-described problem, and as the embroidery progresses, even if the tension applied to the pizza blister increases, the support clip does not easily fall out, and in addition, workability when detaching the support clip An object of the present invention is to provide an embroidery frame that does not degrade.

(Example)

Next, with reference to the accompanying drawings, preferred embodiments of the embroidery frame in the present invention will be described in detail.

1 is a plan view of an embroidery frame 1 of a suitable embodiment. The embroidery frame 1 is a substantially rectangular frame formed by vertical frames 1a, 1a, and horizontal frames 1b, 1b, and is disposed on a sewing machine table in a horizontal state of embroidery sewing machines (not shown). Similarly, it is freely moved in the combining direction of the XY coordinates by a drive source (not shown).

As it turns out from the longitudinal cross section of the embroidery frame 1 in FIG. 3, the support frame 3 is detachably attached to the inner peripheral edge side of the vertical frame 1a (horizontal frame 1b). The support frame 3 is formed with a projection 2 whose upper portion is semicircular in cross section.

Thus, the state in which the support frame 3 is installed in the vertical frame 1a (horizontal frame 1b) of the embroidery frame 1 is a fabric frame which directly supports the wide pizza blisters like the fabric fabric. It becomes a form to be known.

In addition, a rear side of the vertical frame 1a (horizontal frame 1b) is fitted with a suitable spacer 9 for freely sliding the sewing table surface 4.

As shown in FIG. 2 and FIG. 3, the projection 2 of the support frame 3 has a cross-sectional shape which is asymmetrical to the inner circumferential side and the outer circumferential side of the embroidery frame 1. That is, on the outer circumferential side of the embroidery frame 1, a coupling recess 2a gently tightened from the maximum diameter portion of the projection 2 is formed at the base of the projection 2. On the inner circumferential side, a recess 2b is formed in the base of the protrusion 2. The downwardly abutting surface 2c is formed below the largest diameter portion of the protrusion 2 by the formation of the recessed portion 2b.

As shown in FIG. 4, the support clip 6 includes a mounting portion 7 fitted to the protrusion 2 of the support frame 3, and a rotation stopping portion for performing a rotation restraint function for the mounting portion 7. 8). The mounting portion 7 forms a five-sided cross section by bending a steel plate having a predetermined length along the longitudinal direction, and by extending the opposite edge portions at predetermined intervals from each other, both corner portions 7a, (7b) is formed.

Further, the mounting portion 7 has rounded edges of the respective open end portions at both corner portions 7a and 7b in the same direction, and forms engaging portions 7c and 7d in the shape of a round cylinder in the longitudinal direction. Is formed. That is, one coupling portion 7c is fitted into the recessed portion 2b of the protrusion 2 and the other coupling portion 7d is coupled to the coupling recess 2a of the protrusion 2. As for the space | interval of these engaging parts 7c and 7d, the dimension is set so that it may become smaller than the thickness of the base of the said projection 2 in the free state.

Next, as shown in Figs. 4 and 5, the rotation stopping portion 8 has a length substantially the same as that of the mounting portion 7, and is used to bend the steel sheet slightly higher in rigidity than the mounting portion 7 in the longitudinal direction. Thereby, a fixing member 8a fixed to the upper surface of the mounting portion 7, a coupling member 8b connected to one side of the fixing member 8a, and a fabric extending to the other side of the fixing member 8a. The pressing member 8c is formed. In addition, the fixing member 8a of the rotation stopping portion 8 is fixed to the upper surface of the mounting portion 7 by means such as spot welding. Moreover, as shown in FIG. 4, the flat handle 7e is being fixed to the lower side surface of each corner part 7b by spot welding at the center part of the longitudinal direction of the said mounting part 7. As shown in FIG. The handle 7e protrudes upward through the notch 8d formed at the upper end of the rotary stop 8.

5 is a cross-sectional view showing the pizza a in the full length support state of the embroidery frame 1 by the support clip 6. Coupling portions 7a, 7b of the mounting portion 7 in the support clip 6 are coupled to the projection 2 via the pizza water a. In this state, the lower edge of the pressing member 8c of the cloth presses the pizza water a slightly lower than the height of the coupling portion 7c, and at the same time, the edge of the end of the coupling member 8b is supported by the support frame 3. It is intended to be in contact with the upper surface of

Next, the operation of the embroidery frame in the embodiment will be described.

In the case where the pizza a is taut to the embroidery frame 1, the pizza a is placed on the embroidery frame 1, and then the handle 7e is directed outward of the embroidery frame 1. In such a position, the opening of the mounting portion 7 in the support clip 6 is pushed down against the projection 2 from above the pizza water a. As a result, both corner portions 7a and 7b of the mounting portion 7 expand downward while resisting elasticity and move downward, and the engaging portions 7c and 7d are the maximum diameters of the projection 2. When riding over the portion, the coupling portions 7c and 7d are connected to the recesses 2b and the concave recess 2a by the elastic restoring action of both the portions 7a and 7b. Elastically snapped together. That is, the pizza a in the periphery 2 is elastically constricted between the engaging portions 7c and 7d and the projection 2.

In this way, the support clip 6 is attached to the projection 2 over the entire periphery of the pizza a, so that the pizza a is fully supported by the embroidery frame 1. In this state, as described above, the lower edge of the cloth pressing member 8c of each support clip 6 pushes down the pizza water a slightly lower than the engaging portion 7c, and at the same time, the engaging member 8b. The edge of edge) abuts on the upper surface of the support frame 3. In this state, if any embroidery is carried out by embroidery sewing machine (not shown) on the full length supported pizza embroidery (a) in the embroidery frame (1), the sewing wrinkles in the pizza embroidery (a) as the embroidery sewing proceeds This causes the tension acting on the pizza a to gradually increase. For this reason, the pizza a, which is pushed down slightly by the lower edge of the cloth pressing member 8c of the support clip 6, is lifted to the height of the lower end of the engaging portion 7c with the increase in tension. Show a tendency to lose. As a result, the support clip 6 tries to rotate about the outer engaging portion 7d in the mounting portion 7, but the edge of the end of the engaging member 8b is in contact with the upper surface of the supporting frame 3. Therefore, the rotational force is applied to the rotation stopping part 8 about the edge of the end of the coupling member (8b).

By the way, since the rotation stopping part 8 is fixed integrally with the mounting part 7, the rotation stopping part 8 rotates about the edge of the end of the coupling member 8b. Both engaging portions 7c and 7d must be pulled up from the recessed portion 2b and the engaging recess 2a almost simultaneously, which requires a very large force.

In addition, in the embroidery frame of the present embodiment, the upper edge of the coupling portion 7c abuts against the face 2c of the recess 2b in accordance with the increase in the tension of the pizza a. The movement upward of 7c) is reliably regulated. Therefore, even if the tension acting on the pizza a with the progress of the embroidery increases, the supporting clip 6 does not fall out of the embroidery frame 1 by this.

In addition, when opening the pizza water a from the embroidery frame 1, by holding the handle 7e of the support clip 6 and raising it to the inside of the embroidery frame 1, the support clip 6 is inside. It can be easily opened by rotating about the engaging portion 7c of the.
