Abstract

This creation is to provide an improved structure of an integrated safety shoe, including a shoe body, a toe steel plate and a sole steel plate. This creation uses the toe steel plate and the sole steel plate to tie the shoe body at the same time as the shoe body is injection molded. It is integrally wrapped in the upper and the sole, and the outer covering layer of the toe cap is formed on the surface of the toe cap. Because the outer covering layer of the toe cap can be made of leather shoes or cloth different from plastics, it can reach the shoe Because of the novel aesthetic effect of the head, it can be finished by injection molding at one time, making it simple, fast and cost-reducing.

Description

Improved structure of one-piece safety shoes

This creation is about an improvement in the structure of an integrated safety shoe, especially an integrated safety shoe with simple, fast and cost-reducing effects.

Press, please refer to Figure 1, which shows the structure of a conventional safety shoe including a sole 10a, an upper 11a adhered to the sole 10a, and a toe steel plate 12a arranged in the upper 11a. And a sole steel plate 13a arranged in the sole 10a. Wherein, the shoe upper 11a and the shoe sole 10a are combined together by means of adhesion, so they are prone to separation. In particular, the upper 11a of the conventional safety shoe is sewn or glued with a plurality of leather, cloth or plastic materials to form a bent adhesive part 141a, and the toe plate 12a is made of at least two pieces of leather, cloth or The plastic material is wrapped in the toe cap 14a in a sandwich manner. Therefore, it is not only cumbersome and time-consuming to manufacture, but also relatively expensive to manufacture. Especially, it is not easy to make shape changes on the surface of the shoe upper 11a. .

In view of the above phenomenon, the creator of this case is based on years of production experience, and then develops a wider range of practical new models.

That is, the main purpose of this creation is to provide an improvement in the structure of an integrally formed safety shoe; the problem to be solved is that the process of adding one more flap to the toe cap steel plate of the conventional structure can easily increase the time and cost, not only the production The above is more troublesome, time-consuming, and the production cost is also high; Moreover, the back end of the conventional structure of the shoe does not have a metal sheet body, so that it is easy to be affected by the lateral impact of the hard block on the heel in the factory, which may cause the worker's heel to be injured. Improve and break through the problem points;

The technical features for solving the problem include a shoe body, including an upper and a sole formed by injection molding of thermoplastic material, and a receptacle for accommodating a foot is defined between the upper and the sole. Space, the shoe face should have a toe at the front end of the foot; a toe steel plate, the outer end of the toe steel plate is covered with a toe outer cover, the toe outer cover and the toe steel plate The shoe body is integrally wrapped in the toe cap during injection molding, and can be relatively covered above the front end of the foot. The bottom edge of the toe cap steel plate is bent with a folding surface; a sole steel plate is tied to the The shoe body is integrally wrapped in the sole when it is injection molded;

In this way, this creation uses the toe cap steel plate and the sole steel plate to be integrally covered in the upper and the sole while the shoe body is injection molded, and the toe cap outer covering is formed on the toe cap surface , Since the outer covering material of the toe cap can be made of leather shoes or fabrics different from plastics, so as to achieve the novel aesthetic effect of the toe cap, it can be finished by injection molding at one time, making it simple, fast and cost-reduced. The effect.

Please refer to Figures 2 to 3, which are the preferred embodiments of the structure improvement of the one-piece safety shoes of this creation. However, these embodiments are for illustrative purposes only and are not restricted by this structure in the patent application; including:

A shoe body 10, a toe cap steel plate 20, and a sole steel plate 30;

The shoe body 10 includes a shoe upper 11 and a shoe sole 12 formed by injection molding of thermoplastic material. The shoe upper 11 and the shoe sole 12 define a foot (not shown). In the accommodating space 13, the shoe upper 11 has a toe cap 14 corresponding to the front end of the foot;

The outer end surface of the toe cap steel plate 30 is covered with a toe cap outer covering layer 40, wherein the toe cap outer covering layer 40 is made of a plurality of leathers or cloths, and the toe cap outer covering layer 40 is connected to the toe cap steel plate 20. The shoe body 10 is integrally wrapped in the toe cap 14 during injection molding, and can be relatively covered above the front end of the foot. The bottom edge of the toe cap steel plate 20 is formed with a folded surface 21, which can greatly reduce the time and labor cost of bonding and fixing the toe cap steel plate 20 and the toe cap layer 40 by being integrally covered during injection molding.

The sole steel plate 30 is integrally wrapped in the sole 12 when the shoe body 10 is injection molded, and the sole steel plate 30 completely covers the bottom surface of the accommodating space 13. In this creation, the sole steel plate 30 can also only focus on covering a part of the area of the bottom surface of the accommodating space 13 at a specific location.

Please refer to Fig. 4, the safety shoes of this creation are made by first sucking and positioning the toe cap steel plate 20 on a plurality of protruding magnetic blocks 51 at an inner mold 50 corresponding to the toe cap 14. The outer toe cover layer 40 is wrapped on the outer layer of the sole steel plate 30, and the sole steel plate 30 is adsorbed and positioned on the plurality of convex magnetic blocks 52 at the inner mold 50 corresponding to the sole 12, so that the toe steel plate 20 and The sole steel plate 30 maintains a distance from the inner mold 50 by the magnetic blocks 51 and 52. Then, the two side molds 53 and an upper mold 54 are combined with the inner mold 50 to form a mold cavity 55, and then a thermoplastic material is poured into the mold cavity 55 so that the thermoplastic material is in the inner mold 50 and the two sides. The shoe body 10 is formed in the cavity 55 formed by the mold 53 and the upper mold 54. In this way, the thermoplastic material will fill the gap between the toe cap steel plate 20 and the inner mold 50, so that the toe cap steel plate 20 is covered by the thermoplastic material, and the toe cap outer covering layer 40 is formed on the toe cap 14 surface. The thermoplastic material fills the gap between the sole steel plate 30 and the inner mold 50 so that the sole steel plate 30 is covered by the thermoplastic material.

Since the toe cap steel plate 20 of the present invention has the function of supporting and protecting, it can effectively prevent the front end of the worker's foot from being injured by accident; in addition, the sole steel plate 30 of the present invention has the function of blocking and anti-puncture, so it is effective Avoid puncture injuries to the soles of the workers' feet.

In particular, the upper 11 and the sole 12 of the shoe body 10 are integrally formed, so that the upper 11 and the sole 12 can be prevented from being easily separated. The toe steel plate 20 and the sole steel plate 30 are integrally covered in the upper 11 and the sole 12 while the shoe body 10 is injection molded, and the toe outer covering 40 is formed on the surface of the toe 14 Because the material of the outer covering layer 40 of the toe cap can be made of leather shoes or fabrics different from plastics, so as to achieve the novel aesthetic effect of the toe cap 14, it can be finished by injection molding at one time, making it simple, fast and easy to manufacture. The effect of reducing costs.

Moreover, the shoe body 10 injection-molded from a thermoplastic material is easy to use a mold to form various strips, blocks or characters on the surface during molding. Therefore, the shape of the shoe body 10 can also be variability and relatively high. With beauty and texture.

This creation can improve the convenience and usability, and it is indeed deeply practical and progressive. However, no identical products and publications have been published, so that the new patent application requirements are met, and the application is filed in accordance with the law.
