Conventionally, among a pair of male and female front fronts sewn to the joint of both fabrics at the waist of pants, skirts, etc., one hook (male front), particularly a three-hole hook, is used as a presser. A holding part was formed downward at the lower end of the presser foot of the sewing machine, and the engaging part of the hook was pushed into this holding part from below to attach it. Due to the limitations, the rising height is relatively small, making it difficult to freely attach the hook to the holding portion with your fingertips.
このため、例えば実公昭60−24297号公報に開

いる。 For this reason, a male clamping device has been proposed, for example, as disclosed in Japanese Utility Model Publication No. 60-24297.

However, in the case of conventional proposals such as the cited example above, although illustrations and explanations are omitted, in the case of a three-hole hook, if there is a crossing thread between the holes, the needle may be attached to a part of the presser foot. There was a problem that the sewing machine could not sew due to contact. Further, as shown in a perspective view in FIG. 2, the three-hole hook is of a type having a tongue piece T in the center groove 22 of the base plate 20 to prevent the engaging portion from accidentally coming off from the mating female hook. Two holes 23a, 23b,
In the case of the 23c hook, there was a problem in that the holding part (not particularly shown) in the cited example interfered with the tongue piece, making it virtually impossible to insert the hook into the holding part.

提供を目的としている。 The present invention was developed in view of the problems of the conventional methods as described above, and it is possible to securely and immovably set a three-hole hook with a tongue with one touch, and also to prevent removal after sewing. The purpose is to provide an easy presser device.

Therefore, in the present invention, a leaf spring is disposed on the lower surface of the presser foot attached to the lower end of the presser foot arm of the sewing machine, with a gap for inserting the hook, and the leaf spring is attached to the center groove 22 of the base of the hook. By protruding upwardly a dowel that fits into the gap, the hook can be securely held in a snap-like manner by inserting the hook into the gap.

The present invention will be explained below based on examples. FIG. 1 is a top view showing a state in which an embodiment of the hook holding device according to the present invention holds a three-hole hook with a tongue, and FIGS.
A cross-sectional side view taken along line A and line B.B is shown. Reference numeral 1 denotes a presser foot having a substantially L-shape on the side and a T-shape in plan, which is attached to the lower end of the presser arm of the sewing machine by fitting into the groove 1a. A protrusion 2 is formed laterally on the lower surface of the T-shaped leg, a substantially rectangular leaf spring 3 is disposed in contact with the protrusion 2, and the base portion is fixed to the lower surface of the leg with a machine screw 4, The distal end forms a gap G for hook insertion between the distal end and the distal end of the lower surface of the leg. Further, a single dowel 5 is provided on the leaf spring 3 in an upwardly protruding manner, and its diameter is such that it fits into the width of the substrate groove 22 of the hook when the hook is inserted into the gap G. The lower surface of the leg end of the presser foot 1 is rounded to match the contour of the engaging portion of the hook.
以上の構成によつて明かなように、ミシン作業

い。 As is clear from the above configuration, when the sewing machine operator pushes the three-hole hook with tongue into the gap G from the front side in the direction of the arrow shown in FIG.
The back of the folded portion of the engaging portion 21 of the base 20 comes into contact with one side of the protrusion 2 of the presser foot 1, while the dowel 5 snaps into the groove 22 of the base plate 20 and
It is restrained and held in the left-right direction, and even if it is pulled by a crossover thread or the like, there is no risk of the needle breaking due to misalignment.
また、3つ穴部の縫付け終了後、押え腕を上昇

布押え体1から取外すことができる。 Furthermore, after completing the sewing of the three holes, the workpiece can be easily removed from the presser foot 1 by raising the presser arm and pulling the workpiece toward you.
なお、上記実施例においては、突起2は、布押

As explained above, according to the present invention, the hook presser is configured so that it can be set in one step so that it does not shift in the front/back/left/right direction, so insertion is easy and there is no possibility of needle breakage due to misalignment. This eliminates the problem and makes it easy to remove after sewing is completed.
