As shown in FIGS. 1 to 4, the sewing clip C of this embodiment comprises a pair of upper and lower clip pieces 1 and 2 which are integrally molded from hard synthetic resin.

Of the upper and lower clip pieces 1 and 2, the lower clip piece 1 has a flat bottom surface (lower surface) side, and an upper surface side of the lower clip piece 1 protrudes upward in an intermediate portion in the front-rear direction. A lower pivot 10 is formed. Further, the front side of the lower clip piece 1 is configured as a lower holding section 11 having a flat upper surface side, and the rear side is configured as a lower grip section 15 .

An upper pivotal attachment portion 20 is formed in a downward protruding manner in correspondence with the lower pivotal attachment portion 10 of the lower clip piece 1 at an intermediate portion in the front-rear direction on the lower surface side of the upper clip piece 2 . The front side of the upper clip piece 2 is configured as an upper holding section 21 and the rear side is configured as an upper grip section 25 . Furthermore, the front end portion of the upper clamping portion 21 is formed so as to bend downward, and as shown in FIGS. .

The pivot portions 10 and 20 of both clip pieces 1 and 2 are pivotally connected to each other so that the upper clip piece 2 can swing relative to the lower clip piece 1. As shown in FIG. Furthermore, both holding portions 11 and 21 are configured to open and close due to this swinging motion. Needless to say, during this swinging, when both holding portions 11 and 21 are closed, both knob portions 15 and 25 are opened, and when both holding portions 11 and 21 are opened, both knob portions 15 and 25 are opened. It is designed to be closed.

As shown in FIG. 3, a clamping spring 3 composed of a substantially U-shaped leaf spring is provided as a biasing means on the outer periphery of the pivot portions 10 and 20 . The clamping spring 3 is installed so as to sandwich the upper and lower clamping portions 11 and 21 from above and below. As a result, both clamping portions 11 and 21 are biased in the closing direction by the biasing force of the clamping spring 3. When the gripping portions 15 and 25 are pinched in the closing direction against the biasing force, both clamping portions 11 and 21 are clamped. The parts 11 and 21 are configured to expand. Therefore, when the member to be clamped, such as the material 5, is interposed between the widened clamping portions 11 and 21, when the gripping operation of the gripping portions 15 and 25 is released, the clamping portions 11 and 21 are opened as shown in FIG. 21 is configured so as to clamp the fabric 5 by the urging force of the clamping spring 3 .

In addition, as shown in FIG. 4, in the sewing clip C of this embodiment, one side edge of the lower clip piece 1 is integrally formed with a connecting protrusion 41 that protrudes toward one side. When viewed from above (bottom view), the connecting protrusion 41 is formed in a so-called ant shape (dovetail shape) with a large width at the end on the projecting direction side. In this embodiment, the connecting protrusion 41 is configured as one-side connecting means.

Further, the other side edge of the lower clip piece 1 is integrally formed with a connecting recess 42 that opens toward the other side and penetrates in the vertical direction to open both above and below. The connecting concave portion 42 is formed in an ant shape (dovetail shape) corresponding to the connecting convex portion 41 in plan view (bottom view). It is tapered.

In this embodiment, as shown in FIGS. 5 and 6, two or more sewing clips C can be connected by connecting projections 41 and connecting recesses 42 . That is, when the connecting convex portion 41 of another sewing clip C to be connected is fitted into the connecting concave portion 42 of a predetermined sewing clip C from either upper or lower direction through the upper or lower opening of the sewing clip C, the connecting convex portion 41 is connected to the connecting concave portion 42. The projection 41 is attached to connect the two sewing clips C side by side. In this connected state, the connecting convex portion 41 and the connecting concave portion 42 are formed in a dovetail shape, so that the connecting convex portion 41 is configured to prevent the connecting concave portion 42 from coming off sideways. .

In the plurality of connected sewing clips C, the bottom surfaces of the respective lower clip pieces 1 are configured to be flat as a whole. Further, needless to say, in a plurality of connected sewing clips C, each upper clip piece 1 is constructed so as to be able to swing individually, and is constructed so that it can be held independently by the individual sewing clips C. .

Further, in this embodiment, when the connecting projection 41 is pulled out from the connecting recess 42 in either the upper or lower direction, the connecting projection 41 escapes from the connecting recess 42 through the upper or lower opening of the connecting recess 42. , so that the connection between the sewing clips C can be released.

In this embodiment, the connecting projection 41 can be inserted into the connecting recess 42 in a dense state to some extent, and the connection of the connecting projection 41 to the connecting recess 42 cannot be performed carelessly. Therefore, it is possible to prevent the sewing clip C from being unintentionally separated.

Further, in the sewing clip C of the present embodiment, three transverse rib projections 31 to 31 extending continuously in the lateral direction (width direction) and having a mountain-shaped cross section (triangular cross-section) are provided on the upper surface of the upper clip piece 2. 33 are integrally formed. The lateral muscle projections 31 to 33 are arranged in parallel with each other at appropriate intervals in the front-rear direction. The second horizontal muscle projection 32 is arranged at a position 7 mm from the front end position of the sewing clip C, and the third third horizontal muscle projection 33 is arranged at a position 10 mm from the front end position of the sewing clip C. .

These horizontal rib projections 31 to 33 constitute horizontal rib portions that function as scales. For example, as shown in FIG. is sandwiched, the front end position of the sewing clip C is located at a position 10 mm from the edge of the fabric 5, so if sewing along the front end of the sewing clip C, the position 10 mm from the edge of the fabric 5 can be sewn. Accurate suturing is possible. In other words, the width of the seam allowance can be reliably set to 10 mm without using a ruler or the like. Similarly, by using the first and second lateral rib projections 31 and 32, the width of the seam allowance of the material 5 can be set accurately to 5 mm and 7 mm.

In the sewing clip C of this embodiment configured as described above, the connecting projection 41 is formed on one side edge of the lower clip piece 1 and the connecting recess 42 is formed on the other side edge. By detachably connecting the convex portion 41 to the connecting concave portion 42 of the other sewing clip C, the other sewing clip C can be connected side by side. For this reason, as shown in FIG. 7, when the material 5 having the thin portion 51 and the thick portion 52 is to be continuously sewn from the thin portion 51 to the thick portion 52, two connected sewing clips C are used. Thus, a region (periphery of the stepped portion) including the stepped portion 53 formed at the boundary between the thin portion 51 and the thick portion 52 and the thin portion 51 and the thick portion 52 in the vicinity of the stepped portion can be securely held. . That is, the adjacent portions of the two connected sewing clips C are made to correspond to the stepped portion 53 of the cloth 5, and the portion on one side of the stepped portion 53, for example, the thin portion 51, is held by the sewing clip C on one side. At the same time, the portion on the other side of the stepped portion 53, for example, the thick portion 52, is clamped by the sewing clip C on the other side. In this clamping state, each clip C on one side and the other side can clamp the thin portion 51 and the thick portion 52 independently, so that both the thin portion 51 and the thick portion 52 can be securely clamped with a desired strength. be able to. Since the periphery of the stepped portion can be securely clamped in this way, the area from the thin portion 51 to the thick portion 52 through the stepped portion 53 can be smoothly sewn, and the sewn cloth can be finished with satisfactory quality.

On the other hand, in this embodiment, when it is desired to clamp the material 5 over a wide area at once, a necessary number of sewing clips C can be connected as shown in FIG. The dough 5 can be clamped in a desired wide range at once. Furthermore, even when it is desired to pinch the cloth 5 with a strong force, the cloth 5 can be pinched with a desired strength by using a group of clips C connected in a required number.

In addition, when a large number of sewing clips C of this embodiment are to be stored when not in use, as shown in FIG. By doing so, they can be compactly arranged side by side and stored in a compartment (storage part) of a predetermined size such as a sewing box. Therefore, in this embodiment, the sewing clips C are not arranged in a disorderly manner, and can be stored neatly and efficiently, thereby improving convenience.

In addition, in this embodiment, the connecting projection 41 provided on the lower clip piece 1 of the sewing clip C is arranged at a position recessed inward from one side edge of the lower clip piece 1, and Similarly, 42 is also arranged at a position recessed inwardly from the other side edge of the lower clip piece 1 . As a result, when the connecting protrusion 41 of a predetermined sewing clip C is connected to another sewing clip C, one side edge of the lower clip piece 1 of the predetermined clip C and the lower clip of the other clip C The other side edge of the side clip piece 1 is matched, and the two sewing clips C can be connected compactly with good appearance in a state of being brought into close contact without a gap.

Further, in the sewing clip C of this embodiment, a lower bent portion 22 having an arc-shaped outer peripheral cross section is formed at the tip of the upper clamping portion 21, and the upper surface of the lower clamping portion 11 facing the lower curved portion 22 is formed. is formed on a flat surface, even when a thick cloth 5 is sandwiched as shown by the solid line in FIG. Even in this case, the downward bent portion 22 can be reliably pressed against the fabric 5, and the fabric 5 can be held in a stable state. In addition, since the upper surface of the lower clamping portion 11 functions as a flat base surface, the clamped dough 5 is planar (linear in cross section) along the flat upper surface (base surface) of the lower clamping portion 11. ), the suturing work can be performed more efficiently and smoothly, and the convenience can be further improved.

In addition, as described above, the sewing clip C of this embodiment has the horizontal rib projections 31 to 33 that function as scales formed on the upper surface of the upper clip piece 2, so that the seam allowance can be easily set without using a ruler. Convenience can be further improved. Moreover, in the present embodiment, the cross-striated protrusions 31 to 33 have a mountain-shaped cross section and the horizontal streak line is displayed at the tip, so that it is easy to visually recognize, and the alignment work of the lateral streak protrusions 31 to 33 with respect to the fabric 5 can be easily performed. Suturing work can be performed much more smoothly.
