Abstract

(57) [Summary] [PROBLEMS] Instead of fixed nails used for temporarily fixing the upper and the insole in the conventional leather shoe manufacturing process, it is easy to remove, reduce damage to the upper, and can be reused. Provide a secure fixture. SOLUTION: A fixed nail is used for temporarily fixing an upper and an insole in a leather shoe manufacturing process. The fixed pawl is made of a steel plate, and has a pawl handle 51 and a plurality of arranged pawl tips 5.
2 The plurality of claw tips 52 are provided with the claw handle 5.
The teeth are bent at right angles from 1 with the tips of each tooth being sharp, so that they can be easily pressed into the leathery upper. The pawl handle 51 is held by the finger of the left hand, and the fixed pawl 5 is pressed into the object with the right hand, and the upper and the midsole are temporarily fastened and joined in the process of drying. After use,
The fixed pawl is pulled out with a pawl handle.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fixing device for temporarily fixing an upper and an insole in a shoemaking process.

[0002]

[Prior art]

 In the general shoe-making process, first, a model (called a last), which is made of wooden footprints, is prepared, and then the middle sole (the sole is at least the “inner sole” to be laid inside the shoe and the lowest layer of the shoe sole). Is temporarily fixed to the bottom of the last, and the upper formed by bending and sewing the edge is fitted on the last, as shown in Fig. 2. Becomes In the next step, the space between the upper and the insole is fixed by sewing or cement bonding (adhesive), but cement bonding (adhesive) is often used in current industrial shoes.

[0003]

[Problems to be solved by the invention]

 At the time of bonding, it is difficult to work with an instant-dry adhesive, which is not widely used in industry.Therefore, general slow-drying adhesives are often used. Is not dried and easily falls off, whether air-dried or heated. Once dropped, the already dried adhesive on the upper is difficult to peel off, making its treatment extremely difficult and time-consuming. Therefore, nails have been used in the prior art to fix first, shortly after the bonding is completed. However, once the nail is attached, it is difficult to remove it, and the upper is easily damaged when using a nail removal tool.

The present invention has been made in view of this type of problem, and an object of the present invention is to provide a suitable upper and an insole fixing device that can replace conventional nails.

[0005]

[Means for Solving the Problems]

 The present invention provides a fastener for temporarily fixing an upper and an insole in a leather shoe manufacturing process, which has a pawl structure made of a steel plate, wherein the pawl structure has a pawl handle and a plurality of arranged teeth. The plurality of teeth are bent at a right angle (about 90 °) from the nail handle, and each of the plurality of teeth has a pointed end.

When using the fixed pawl of the present invention, for example, when grasping the tab with the left hand, pushing in the pawl body (teeth) with the thumb of the right hand, or lightly hitting with a small hammer, and then removing it after use In this case, it is only necessary to remove the fixed pawl from the pawl handle, which is very convenient.

[0007]

[Embodiment of the invention]

 Here, an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an upper 1 cut and formed in a pre-process of a general leather shoe. After the upper has been cut in the previous step, the shoe is formed so that the edge is bent and wrapped around by applying a fold sewing to the edge 11, and then the heel 12 is sewn.

FIG. 2 is a schematic diagram in which the upper is fitted to a last. Before this, the insole 3 has already been temporarily fixed to the bottom surface of the last 2, and the upper 1 has been bonded to the insole with an adhesive. As already mentioned above, the quick-drying adhesive makes it difficult to work, so a slow-drying adhesive is often used. (Separation) occurs, and the upper 1 and the insole 3 may be completely or partially separated from each other. Generally, nails 4 are used, and after the adhesive between the upper 1 and the insole 3 has completely dried, nails that have been nailed are pulled out one by one with a nail pulling tool. It is laborious, and nailing tools often damage the edge of the upper.

FIG. 3 and FIG. 4 are an enlarged four-sided view and a three-dimensional perspective view of the fixed pawl according to the present invention, respectively. Actually, the length of the fixing nail in the present invention is around 2 cm except for the bent portion, and is made of a thin steel plate having high elasticity. The left end is a pawl handle 51, and the right end is a pawl tip 52 (tooth) arranged in a tooth shape and having a sharp end. The fixed pawl is formed by bending a steel sheet having the shape shown in the drawing at a substantially right angle. In the case of using this, for example, the user grips the tab 51 with the finger of the left hand, and further presses the tip 52 of the tab with the right hand against the edge of the upper 1 as shown by reference numeral 5 in FIG. If the upper end 52 is not press-fitted due to the hardness of the upper material, a small hammer may be used. After the adhesive on the edge of the upper 1 and the inner bottom have been dried, the fixing pawl 5 may be pulled out by using a pliers or, in some cases, a finger with a pawl. Easy to temporary fix and pull out, all pulled out nails are reusable next time, more convenient and economical than nailing, and most importantly damage uppers when pulling out It is not.

Although the fixed nail of the present invention has a simple structure, it has creativity and practicality, and shoemakers who have tried this fixed nail are always acclaimed.

[0012]

[Effect of the invention]

 According to the present invention, advantages such as reduction of upper damage at the time of extraction as described above can be obtained.
