DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to a bottomless rainproof shoe cover assembly including a shoe cover and a fixture. The shoe cover is formed into one body by injection molding and combined with the fixture. One side of the shoe cover is provided with a lateral opening. The edge of the shoe cover is provided with a fastening tape. The lower periphery of the shoe cover is provided with a plurality of protrusions. The protrusions enclose to form a fixing trough on the top surface of the shoe cover. Both sides of the fixing trough are provided with a positioning hole respectively. The fixture is accommodated and positioned in the fixing trough for covering the shoe cover and keeping it in a desired shape. With the combination of the integrally-formed shoe cover and the fixture, the degree of coverage and convenience in use are increased, while the manufacturing process and material waste are reduced.
With reference to FIGS. 2 and 7, the bottomless rainproof shoe cover 1 is formed into one body by injection molding of plastic materials. The above-mentioned plastic materials are green materials, in which a suitable ratio of biodegradable materials are blended for promoting landfill decomposition and incineration. The fixture 2 is configured to fix the bottomless rainproof shoe cover 1 onto the surface of a shoe.
The bottomless rainproof shoe cover 1 is formed into one body by injection molding, which has a shape similar to that of a boot. The shoe cover 1 is open near the bottom of the shoe, so that the shoe cover 1 is bottomless. One side surface of the shoe cover 1 has a lateral opening, so that a user can put on the shoe cover 1 easily and quickly. The bottomless rainproof shoe cover 1 is provided at suitable positions with stitching lines, leather grains, or geometrical patterns during the injection molding, so that the bottomless rainproof shoe cover 1 looks like a riding boot. Since the shoe cover 1 is bottomless, it is capable of fitting shoes having different shapes and sizes. Fastening tapes 10, 100 are provided on both sides of the lateral opening of the shoe cover 1, in which the fastening tapes 10, 100 comprise a narrow fastening tape 10 and a wide fastening tape 100. By this arrangement, the shoe cover 1 is adjustable to fit the shoes having different lengths and outer profiles.
The lower periphery of the bottomless rainproof shoe cover 1 is provided with a plurality of protrusions 11 for promoting the fixation of the shoe cover 1 on the shoe and the resistance of abrasion when contacting the ground. The top surface of the front section of the bottomless rainproof shoe cover 1 is provided with a plurality of protrusions enclosing to form a fixing trough 12. Both sides of the fixing trough 12 are provided with a positioning hole 120 respectively. The fixture 2 is accommodated in the fixing trough 12. Both sides of the fixture 2 are provided with a fixing hole 20 respectively to correspond to the positioning hole 120.
The fixture 2 is formed like a horse's hoof and is flexible for deformation. Both sides of the fixture 2 are provided with the fixing hole 20 respectively. Two ends 201 of the fixture 2 are formed with at least one bending portion to increase the durability and degree of coverage. The fixture 2 is fixed into the fixing trough 12 of the bottomless rainproof shoe cover 1. In use, the bottomless rainproof shoe cover 1 is put on the surface of the shoe via the lateral opening, and then the fixture 2 is fixed into the fixing trough 12, whereby the bottomless rainproof shoe cover 1 can be firmly put on the surface of the shoe.
Please also refer to FIGS. 3 and 4. As mentioned in the above, the bottomless rainproof shoe cover 1 is formed into one body by injection molding of plastic materials. The lower periphery of the bottomless rainproof shoe cover 1 is provided with the protrusions 11 for promoting the fixation of the shoe cover 1 onto the shoe and the resistance of abrasion when contacting the ground. As shown in FIGS. 3 and 4, since the visibility is not good on rainy days, and even much worse on heavy cloudy days or at night, LED lamps 10 may be mounted between the protrusions 11 formed on the lower periphery of the bottomless rainproof shoe cover 1. Alternatively, reflective materials 111 or light-absorbing materials are blended in the shoe cover 1 during the injection molding, thereby increasing the safety when using on rainy or heavy cloudy days and at night.
Please refer to FIGS. 5 and 6. The bottomless rainproof shoe cover 1 is put on the outer surface of the shoe to keep rainwater off legs of the user on rainy days. When the bottomless rainproof shoe cover 1 is put on the outer surface of the shoe, the fixture 2 is fastened onto the outer surface of the shoe cover 1. The fixture 2 may be embodied as a fixture 2′ without the ends 201 as shown in FIG. 5. Both sides of the fixture 2′ are formed with a fixing hole 20′ to correspond to the positioning hole 120 on both sides of the fixing trough 12. Then, a fastener 202 is disposed through the fixing holes 20′ for fixing the fixture 2′ onto the shoe. Alternatively, a binder may be used for this purpose. The fastener 202 may be made of plastics, fiber-reinforced plastics or metals. In the fixture 2 having the ends 201 as shown in FIG. 6, each of the ends 201 of the fixture 2 is formed with at least one bending portion. Further, the bottom surface of the fixture 2 is provided with skid-proof embossments for providing a skid-proof effect. The surface of the fixture 2 or 2′ is coated with a reflective coating or adhered with a reflective film, thereby increasing the safety at night. Further, the fixture 2 or 2′ may be embodied as a serpentine spring to reduce the production cost.
According to the above, by using the bottomless rainproof shoe cover assembly of the present invention including an integrally-formed shoe cover and the combined fixture, the amount of materials, time for injection molding, weight and volume of the final product can be reduced. Further, the present invention is capable of fitting shoes having different sizes and being rapidly put on or taken off.
