  The present invention relates to an embroidery frame, and more particularly, to an embroidery frame that can match the relative positions of a support frame and a presser frame with a simple configuration and can cope with various fabric thicknesses.

  Various embroidery frames for attaching a work cloth to an embroidery sewing machine have been proposed. A conventional embroidery frame includes an outer frame and an inner frame. The inner frame is fitted into the outer frame, and the outer frame is tightened by a fastening member such as a screw provided on the outer periphery of the outer frame. The work cloth was sandwiched between the peripheral portion and the outer peripheral portion of the inner frame. However, it is very difficult to tighten the fastening member while stretching the work cloth. If the work cloth is found to be loose after the fastening member is tightened, the fastening member is loosened and the work cloth is stretched. Later, the fastening member must be retightened, which requires a great deal of labor and time.

Therefore, Patent Document 1 has an upper frame (corresponding to a presser frame) and a lower frame (corresponding to a support frame), and adsorbs the upper frame and the lower frame by a magnetic force. An embroidery frame that can hold a work cloth therebetween is disclosed. The embroidery frame includes a lower frame, an upper frame, a fixed portion to which the lower frame is fixed, a movable portion that supports the upper frame, and the like, and the movable portion is rotatably connected to the fixed portion. . Therefore, when attaching the work cloth to the embroidery frame, the upper cloth is rotated with respect to the fixed part together with the movable part while the work cloth is placed on the lower frame. It is clamped by the magnetic force in the frame.

Next, the operation and effect of the embroidery frame 1 described above will be described.
According to the embroidery frame 1, since the guide portion 11 for guiding the presser frame 3 is formed on the support frame 2, the presser frame 3 is guided to a predetermined position on the support frame 2, and the support frame 2 and the presser frame 3 are guided. The relative position can be easily expressed. Therefore, the configuration for connecting the support frame 2 and the presser frame 3 to align the relative positions of the support frame 2 and the presser frame 3 can be omitted, and the configuration of the embroidery frame 1 can be simplified. Since the support frame 2 and the presser frame 3 are configured to be detachable separately, the degree of freedom of movement of the presser frame 3 is increased, and the presser frame 3 interferes with the sewing needle or the embroidery sewing machine when the presser frame 3 is removed. Can be prevented. By omitting the configuration for connecting the support frame 2 and the presser frame 3, the work cloth is not obstructed by the connecting portion, so that the work cloth 5 larger than the embroidery frame 1 can be set and sewn. .

  Since the guide portion 11 is formed to be inclined outward, the work cloth 5 can escape along the guide portion 11, and the work cloth 5 having a thicker cloth thickness than the case where the guide portion 11 is formed vertically can be obtained. Can also be pinched. Since the upper end part of the guide part 11 is located above the upper surface part of the presser frame 3, the presser frame 3 can be easily guided to a predetermined position. As described above, the strength of the support frame 2 can be improved by forming the guide portion 11 high upward as described above and over the entire outer periphery of the sandwiching portion 10.

  Since the folding | returning part 24 was formed in the upper end part of the guide part 11, the intensity | strength of the guide part 11 is improved. In addition, when the work cloth 5 protruding from the presser frame 3 is sandwiched between the clip 25 and the guide portion 11, not only the front end portions 26 a and 26 b of the clip 25 but also the middle portion of the clip 25 is supported by the folded portion 24. Therefore, the clip 25 is stabilized, and the folding portion 24 can prevent the clip 25 from coming off. In addition, since the guide portion 11 is formed to be inclined outward, the clip 25 attached to the guide portion 11 does not interfere with the embroidery sewing machine or the like.

  Since the clamping portion 10 is formed of a thin metal plate, the work cloth 5 attached to the embroidery frame 1 hardly floats from the needle plate of the embroidery sewing machine, stabilizes the thread tension, and has a sewn product quality after sewing. improves. By forming the presser frame 3 from a synthetic resin mixed with magnetic powder, the influence of the metal parts of the embroidery sewing machine such as a needle plate can be suppressed compared to the case where the support frame 2 is formed of a permanent magnet. In addition, the presser frame 3 can be prevented from being damaged due to dropping or the like. By configuring the upper end portion of the handle portion 41 of the presser frame 3 to be located above the upper end portion of the guide portion 11, the handle portion 41 can be easily removed when the presser frame 3 is removed.

Next, a modified example in which the above-described embodiment is partially modified will be described.
1) As shown in FIG. 9, an embroidery frame 1A may be configured. In this embroidery frame 1A, the corners of the guide portion 11A of the support frame 2A are not connected, and rectangular windows 60 are formed at predetermined intervals in the guide portion 11A. In the embroidery frame 1A, the corner of the guide portion 11A is eliminated and the rectangular window 60 is formed, so that the embroidery frame 1A can be reduced in weight. In addition, a clip can be used instead of a clip by piercing the rectangular window 60 with a needle stuck to a work cloth protruding from the presser frame.

  2) In the above-described embodiment, the outer periphery of the clamping unit 10 and the outer periphery of the pressing unit 40 are configured to coincide with each other, but the outer periphery of the clamping unit 10 may be larger than the outer periphery of the pressing unit 40. For example, if it is configured such that a gap of about 2 mm is formed in the horizontal direction between the outer periphery of the holding unit 10 and the outer periphery of the pressing unit 40, the cloth can be held to a thickness of about 6 mm.

  3) In the above-described embodiment, there is only one type of presser frame 3. However, a plurality of types of presser frames may be used depending on the thickness of the work cloth. In particular, when using properly depending on the cloth thickness, it is desirable to set the magnetic force of the presser frame corresponding to the cloth thickness.

  4) In the above-described embodiment, the presser frame 3 is made of synthetic resin, but may be made of synthetic rubber. Further, the support frame may be made of a permanent magnet, and the presser frame may be made of a magnetic material that is not a permanent magnet, or both the support frame and the presser frame may be made of a permanent magnet.

  The present invention is not limited to the embodiments described above, and those skilled in the art can implement the invention by adding various modifications to the embodiments without departing from the spirit of the present invention. The present invention includes those modifications.
