Description of the preferred embodiment

Before the footwear according to the invention is described in details, it should be noticed that the similar units in the following contents are explained by the same number.

Referring to Figure 1 and 2, the first embodiment of the reflective vulcanized rubber shoe, footwear or boot, includes a shoe body unit 1 and several reflective units 2. The reflective units 2 are made of a durable reflective material which can withstand high temperatures while vulcanizing. These materials are in particular beneficial on rubber boots, either the reflective material is applied on textile and then laminated on neoprene or a directly print on rubber.

The shoe body unit 1 includes a sock 1 1 and a rubber shoe body 12, which wraps the outside of the sock 1 1 . The sock 1 1 has a rubber inner side 1 1 1 which is made of rubber and surrounds and defines a wearing space 10, an inner fabric layer 1 12 which wraps the rubber inner side 1 1 1 and faces one side of the wearing space 10, and an outer fabric layer 1 13 which wraps the rubber inner side 1 1 1 and back to one side of the wearing space 10. The rubber inner side 1 1 1 is made of Chloroprene Rubber (CR), Styrene-

Butadiene Rubber(SBR), or the two mixed in any proportion. The rubber inner side 1 1 1 has a shoe-shaped part 1 14 which wraps the users' foot completely and a tubular part 1 15 formed by extending the shoe-shaped part upward. The inner fabric layer 1 12 is made of elastic fabric or breathable fabric to provide a soft and comfortable tactility for the users. The outer fabric layer 1 13, which is made of fabric, wraps around the surface of the tubular part 1 15 for an aesthetic effect, but when implemented, it can also be made of reflective fabric. The rubber body 12 includes several rubber slices 121 , which wrap the sock 1 1 , and a sole plate 122, which adheres to the bottom of the sock 1 1 . The rubber slices 121 , which adhere to the surface of sock 1 1 by partially overlapping, can wrap the shoe-shaped part 1 14 completely and partial areas before and behind the tubular part 1 15. The sole 122, which is made of rubber, is thicker than the rubber slice 121 .

As illustrated in closer detail in fig. 3, the reflective units 2 are evenly distributed to the outer fabric layer 1 13 in mottled form. Each reflective unit 2 includes a reflective layer 21 , a heat-resisting protective layer 22 coated on the reflective layer 21 , and a hot melt adhesive layer 23 which connects the reflective layer 21 and hot melt adhesive layer 23 fixed to the outer fabric layer 1 13 of the sock 1 1 . The reflective layer 21 has several glass beads 21 1 , which adhere to the hot melt adhesive layer 23. When being shined on, the glass beads 21 1 reflect the light and provide a reflective effect. Certainly when implemented, the reflective layer 21 also has several beads that can reflect the lights, not limited to this embodiment, the heat-resisting protective layer 22 is located at the surface of the reflective layer 21 to protect the glass beads 21 1 . Its transparency enables the light to enter the reflective layer 21 and to influence the reflective effect of the reflective layer 21 . The layer 23 is made of hot melt adhesive and has the adhesive characteristic, so the reflective layer 21 can adhere to the shoe body unit 1 . The hot melt adhesive layer 23 is melted when being heated at a given temperature. The materials of the hot melt adhesive layer 23 in the shown embodiment include basic resin, tackifier, antioxidants and others. They are melted when being heated at the temperature of 1 20 to 160 degrees Celcius.

The following explains the manufacturing process of the reflective vulcanized rubber shoes: Firstly, make the rubber inner side 1 1 1 of the sock 1 1 , and make the reflective unit 2 adhere to the outer fabric layer 1 13 by printing and transferring. Next, use the inner fabric layer 1 12 and the outer fabric layer 1 1 3 to wrap the rubber inner side 1 1 1 by sewing. Then, wear the sock 1 1 to a shoe last and wrap the sock 1 1 with rubber slices 1 21 by adhering based on its structure, for example, the heel and the tip are fragile so these parts can be wrapped with more layers. Then, make the sole 1 22 adhere to the bottom of the sock 1 1 and wrap the sock 1 1 with the rubber shoe body 1 2 to form the rubber shoe without the vulcanization .

Besides, at this temperature, the hot melt adhesive 23 of the reflective unit 2 will be infiltrated in the outer fabric layer 1 13 because of heating and after the rubber shoe is cooled down, setting and fixation of the hot melt adhesive to the outer fabric layer 1 13 has taken place. Thus, the reflective unit 2, which has adhered to the sock 1 1 , can be fixed to the sock 1 1 more steadily at the same time with vulcanization and heat-treatment. The processing process will be simplified and the falling-off problem of the reflective unit 2 will be

improved. In this embodiment, the materials of the rubber slice 121 and the sole 122 are raw rubber and made by vulcanization and heat-treatment after adhering.

However, when implemented, the sole plate 122 can adhere to the bottom of the sock 1 1 after vulcanization and heat-treatment, or the sole 122 is not made of rubber. It is not limited to this embodiment.

In conclusion, the reflective vulcanized rubber shoe can make the reflective unit 2 adhere to the shoe body unit 1 by the hot melt adhesive 23 of the reflective unit 2 before vulcanization and heat-treatment of shoe body unit 1 , and at the same time with vulcanization and heat-treatment of shoe body unit 1 , make the hot melt adhesive 23 melt combined with the shoe body unit 1 more steadily to simplify the manufacturing process and improve the stability of the reflective unit 2, so the purpose of the present invention can be achieved.

Referring to Figure 4, the structure of the second embodiment of the present invention is roughly the same as with the first embodiment. The difference lies in that the reflective unit 2 adheres to the rubber shoe body 12. The reflective unit 2 will adhere to the rubber slice 1 21 by printing and transferring . The reflective unit 2 will make the rubber slice 1 21 outward adhere to the surface of the sock 1 1 and wrap it. When processing the rubber shoe with vulcanization and heat- treatment, the hot melt adhesive of the reflective unit 2 will melt due to the vulcanization and heat-treatment and melt-combined with the softened rubber slice 121 . Thus, it will adhere to the rubber body 12 more steadily.

When implemented, the reflective unit 2 can also adhere to the sock 1 1 and the rubber shoe body 12. The adhering location can be designed according to the requirements, not limited to this embodiment. Besides, the rubber shoe can also include a reflective unit 2, which adheres to the shoe body unit 1 in the form of sheets. With the reflective function of the reflective unit 2, the safe reflective effects can also be achieved, not limited to this embodiment.

The above is simply the embodiments of the present invention and cannot be limited to define the implementing scope of the invention, namely, any simple equivalent transformation and modification based on the claims and

specification of this invention belongs to the scope of this invention.
