Description

The present invention relates to a grip gavel used in a sewing operation for cutting a thread or releasing a sewn thread.

Generally, in a sewing operation, a gripping scissors (thread trimming scissors) are used to cut a thread sewn on a cloth such as a sewn clothing or to release a sewn thread. This is a base that elastically supports an upper arm part having an upper blade part at one end of a U-shaped ridge body part and a lower arm part having a lower blade part at the other end. Both tips are pointed.

However, the gripper with sharp tips at the upper and lower blades may pierce the arm or hand during work and cause injury. In addition, when cutting a thread sewn on a fabric, if the handle is sharpened with a sharp tip, the fabric is often cut into a defective product. Further, when unraveling the thread sewn on the fabric, generally the perforation and the gripper are used. However, since the perforation and the gripper are used alternately, there is a problem that the working efficiency is lowered. In particular, when three yarns are sewn to the fabric in parallel, it is an operation requiring skill to draw out only the middle yarn without damaging the yarns on both sides.

For this reason, a grip gavel (Patent Document 1) has been proposed in which a perforation is pivotally attached to one upper arm, but this must be used by rotating the perforation each time it is used. Also, when using perforations, there was a risk of cutting the fabric with an excessively sharp edge.

The present invention improves the above problems, and provides a grip gavel that can cut only the yarn without cutting the fabric and can be pulled out and unwound without damaging the yarn without using perforations.

A grip gavel according to claim 1 of the present invention is a grip gavel that elastically supports an upper arm part having an upper blade part on the distal end side and a lower arm part having a lower blade part on the distal end side at the base part. The outer end portions of the upper blade portion and the lower blade portion are curved inward from each other, and curved concave portions are respectively formed in the portions facing the upper and lower blade portions on the distal end side.

The grip gavel according to claim 2 of the present invention is characterized in that, in claim 1, a curved portion is formed at a boundary portion between the curved concave portion and the upper and lower blade portions.

A gripping scissors according to claim 3 of the present invention is the gripping scissors according to claim 1, wherein the bent portion having an L shape is provided at the intermediate portion of the upper arm portion and the lower arm portion facing each other, and the tip of the bent portion is in a state where the scissors are opened. The projections are provided so as to be engaged with each other.

According to the gripping scissors according to claim 1 of the present invention, the tip of the lower blade part can be inserted into the seam, and can be pulled out by being hooked into the curved recess, and the scissors and the perforation are formed integrally. The yarn can be unwound and cut without cutting the fabric. In addition, since the concave portions are formed on both sides of the upper blade portion and the lower blade portion, and there is no directionality for gripping the grip handle, it can be used in any direction.

Further, according to the grip gavel according to claim 2, since the curved portion is formed at the boundary portion between the curved concave portion and the upper and lower blade portions, the thread caught by the curved concave portion can be smoothly smoothed between the upper blade portion and the lower blade. Can be moved.

According to the grip gavel according to claim 3, an L-shaped bent part is provided in the middle of the upper arm part, and an L-shaped bent part opposite to the bent part is provided in the middle of the lower arm part, With the upper blade portion and the lower blade portion open, the tips of both bent portions engage with each other and act as a stopper, preventing the upper arm portion and the lower arm portion from opening more than necessary. The blade part and the lower blade part can always maintain a contact state.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a grip handle. The upper arm 2 and the lower arm 3 are connected to each other by a shaft 4 at their base end portions so as to be opened and closed, and elastically by a coil spring 5 attached to the shaft 4. Is supported. An upper blade portion 6 is formed on the distal end side of the upper arm portion 2, and a lower blade portion 7 is formed on the distal end side of the lower arm portion 3 so as to face the upper blade portion 6, and the upper blade portion 6 and the lower blade portion 7 are engaged with each other. It is designed to cut.

Furthermore, the distal end outer sides of the upper arm portion 2 and the lower arm portion 3 are curved inward from each other to form distal curved portions 8 and 8. Further, in the vicinity of the tips of the upper blade portion 6 and the lower blade portion 7, curved concave portions 9, 9 are formed. Further, curved portions 10 and 10 are formed at the boundary portion between the upper blade portion 6 and the concave portion 9 and at the boundary portion between the lower blade portion 7 and the concave portion 9, respectively.

Further, an L-shaped bent portion 12A as shown in FIG. 2 is provided in the middle of the upper arm portion 2, and an L-shaped bent portion 12B opposite to the bent portion 12A is provided in the middle of the lower arm portion 3, as shown in FIG. In a state where the upper blade portion 6 and the lower blade portion 7 are opened, the bent portions 12A and 12B are provided so that the distal ends thereof are engaged with each other.

As shown in FIG. 3, the gripping spatula 1 having the above-described configuration is configured such that when the thread 15 sewn on the fabric 14 is cut, the gripping spatula 1 is gripped by the hand 16 and is placed in the horizontal position at the tip of the lower blade portion 7. Is inserted into the seam, hooked into the curved recess 9 and pulled up. At this time, the distal end outer side of the lower blade portion 7 is formed with an inwardly curved distal end bending portion 8, so that it does not break even if the distal end hits the fabric 14. Next, as shown in FIG. 4, the handle 1 is slightly lifted, the thread 15 hooked on the curved concave portion 9 is slid from the curved portion 10 to the lower blade portion 7, and the upper blade portion 6 is pushed down, The thread 15 can be cut.

In this way, the tip of the lower blade portion 7 is inserted into the seam, hooked on the curved concave portion 9 and pulled up, so that the perforation and the perforation are formed integrally without using the perforation as in the prior art. The thread 15 can be unwound or cut without cutting. Further, the recesses 9 are formed on both sides of the upper blade portion 6 and the lower blade portion 7 and have no directionality for gripping the gripper 1, and can be used in any direction.

Also, an L-shaped bent portion 12A is provided in the middle of the upper arm portion 2, and an L-shaped bent portion 12B opposite to the bent portion 12A is provided in the middle of the lower arm portion 3, and the upper blade portion 6 and Since the tips of the bent portions 12A and 12B are provided so that the lower blade portion 7 is open, the upper arm portion 2 and the lower arm portion 3 are prevented from opening more than necessary, The blade part 6 and the lower blade part 7 can always maintain a contact state.

FIG. 5 shows another embodiment of the present invention, an upper arm portion 2 having an upper blade portion 6 on one tip side of a U-shaped ridge body portion 17 whose base portion is elastically supported, The lower arm portion 3 provided with the lower blade portion 7 on the other tip side is elastically supported by the base portion, and the other configuration is the same as that of FIG. 1 except for the L-shaped bent portion.

It is a side view of a grip gavel according to an embodiment of the present invention. It is sectional drawing of the grip gavel which shows the bending part of FIG. It is a perspective view which shows the state which has pulled out the thread | yarn using the handle gavel of FIG. It is a perspective view which shows the state which has cut | disconnected the thread | yarn from the state of FIG. It is a side view of a grip gavel according to another embodiment of the present invention.
