  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention provides a bottomless rainproof shoe cover capable of being rapidly put on and taken off. For the sake of simplicity in the following description, a shoe cover pair is generally described using only a single shoe cover.
  • Referring to FIG. 1 and FIG. 2, a bottomless rainproof shoe cover 1 (one of a pair of shoe covers of the present invention) comprises a front cover sheet 10, a rear cover sheet 11, a framing strip 12 and a fixture 13.
  • The front cover sheet 10 is substantially in the form of a cover body, is made of thermoplastic polyurethane (TPU) or thermoplastic silicone, and made by thermal compression molding, injection molding, or liquid injection molding. Alternatively, the front cover sheet 10 may be a laminated long fiber tissue or a thermoplastic mesh, which may be, for example, made of polypropylene (PP), polyethylene terephthalate (PET), or nylon. Two rows of embedding protrusions 101 are formed along an interior circumference of the front cover sheet 10 and the above-mentioned framing strip 12 is embedded between the embedding protrusions 101. Glue fills the embedding protrusions 101 to affix the framing strip 12 between the two rows of embedding protrusions 101. Although two rows of embedding protrusions 101 are disclosed, other means of embedding the framing strip 10 along the interior circumference of the front cover sheet 10 are envisaged and possible in the present invention.
  • The rear cover sheet 11 is substantially in the form of a hollow sleeve having an “L” shape and may be, for example, made of thermoplastic polyurethane (TPU) or thermoplastic silicone, and may be formed by thermal compression molding, injection molding, or liquid injection molding. Two ends (not labeled but can be referred to FIG. 6) are formed on the rear cover sheet 11. The two ends can each overlap the other to some extent. Fastening elements 110, 111 are formed on one and the other of the two open ends, respectively.
  • The front cover sheet 10 and rear cover sheet 11 each have a front end and a rear end, and are brought together at one of their respective ends. Then, a fixture 13 is fixed onto the joint between the front and rear cover sheets 10, 11. The main body of the bottomless rainproof shoe cover 1 is thus formed.
  • Then, the framing strip 12 is laid along the front cover sheet 10 and formed as a ladder shape along the front-most end of the front shoe cover 10, as shown in the figures. The framing strip 12 may be implemented with a shape memory wire, a thin wire cable, or a thin spring. The plastic material for the framing strip 12 may be Polyperpropylene (PET), nylon, poly-carbonate (PC), polyoxymethylene (POM), or acrylonnitrile-butadiene-styrene (ABS). More details about the framing strip 12 are provided in the following.
  • The fixture 13 has two symmetrical portions (as shown in FIG. 3) and fixing elements 133 are formed thereon, respectively. Each of the fixing elements 133 has a respective fixing hole 1330 formed thereon. The framing strip 12 is not only embedded and fixed between the embedding protrusions 101 by way of the glue as discussed above, but also has two ends that may be inserted into the respective fixing holes 1330. In this manner, the bottomless rainproof shoe cover 1 is further reinforced in its profile.
  • The fixture 13 is approximately a “C” shaped clip and comprises a spring 130, a buffering piece 131, slip resisting elements 132, fixing elements 133 and a cover strip 134. The spring 130 is bent into the shape of a “C” with two wings thereof flexed respectively like a hairpin. The spring 130 may be formed from a snake spring. A buffering material 131 is disposed along the interior rim of the spring 130 and may be formed from rubber or silicon or inflated versions thereof. In this way discomfort arising from direct contact and abrasion between the spring 130 and the shoe cover sheet portion therebelow is avoided. A cover strip 134 covers the spring 130 and buffering material 131 and through which the spring 130 and buffering material 131 are fused together with the front and rear cover sheets 10, 11. The two wings of the spring 130 are bonded and affixed with the fixing elements 133, which are disposed on the spring 130, for fixing the two ends of the framing strip 12. The slip resisting elements 132 are disposed on a top face and a bottom face of the two wings of the horizontal portions of the fixture 13 (the spring 130, and termed as upper and lower slip resisting elements 132), respectively, to resist any slippage occurring between the spring 130 and the slip resisting elements 132. The slip resisting elements 132 may be implemented by grids or dot embossments, so that wear-resistance and endurance of the shoe cover are enhanced. With this fixing effect, the bottomless rainproof shoe cover 1 can be put on and taken off rapidly and user convenience and abrasion resist functions thereof can be provided therefor.
  • In an embodiment, the front and rear cover sheets 10, 11 may be formed in a singe body by injection molding. Further, the front and rear cover sheets 10, 11 may be additionally combined with a framing strip 12 and a fixture 13. Regardless of whether the front and rear cover sheets 10,11 are formed in a single body or combined, the framing strip 12 may be omitted. In embodiments without the framing strip 12, the front-most portion of the front cover sheet 10 may be enhanced for structural strength. A bottomless rainproof cover sheet 1 without the framing strip 12 is thus formed.
  • Referring to FIG. 3, FIG. 4A, FIG. 4B, FIG. 5 and FIG. 6, when the shoe cover is put on, the buffering piece 131 is disposed against the side portions of the shoe cover and the two horizontal wings of the fixture 13 clip the indented portion 140 on the shoe bottom. The slip resisting elements 132 are disposed against the upper and lower faces of the two wings of the fixture 13. The upper part of the slip resisting elements 132 can enhance the fixing effect of the shoe cover, while the lower part of the slip resisting elements 132 can increase the endurance of the shoe cover.
  • In addition, the ladder shaped portion formed by the front part of the framing strip 12 is located at the front rim A of the front cover sheet 10, so as to reduce the possibility of abrasion with the ground of the front portion of the front cover sheet 10 and improve the endurance of the shoe cover.
  • Referring to FIG. 4A and FIG. 4B, the embedding protrusions 101 are disposed on a wall of an interior circumference of the front cover sheet 10 for receiving and fixing the framing strip 12 (described in the sense that the framing strip 12 is embedded in the embedding protrusions 101). In addition, glue is filled between the protrusions 101 for further fixation of the framing strip 12. The framing strip 12 may be formed from a shape memory wire, a thin wire cable, or a thin spring. At the same time, the ladder shaped portion formed by the front part of the framing strip 12 is located at the front rim A of the front cover sheet, so as to reduce the possibility of abrasion with the ground of the front portion of the shoe and shoe covers and improve the endurance of the shoe covers.
  • Referring to FIG. 5, the fixture 13 is fused between the front cover sheet 10 and rear cover sheet 11. The fixture 13 has two wings, which are welded or nailed to a fixing element 133, respectively. In the center of each of the fixing elements 133, a tube-like fixing hole 1330 is formed, respectively. The two ends of the framing strip 12 are inserted into the fixing holes 1330, respectively. As such, the structural strength of the profile of the front cover sheet 10 is enhanced.
  • Referring to FIG. 6, the rear cover sheet 11, as above-mentioned, has two ends, which can be overlapped to some extent. On the two ends, an inner side of one of the two ends has a fastening element 111 disposed thereon, while an outer side 110 of the other end has a fastening element 110 disposed thereon. When a user puts the shoe cover on his shoe, the fastening elements, 111, 110 couple or adhere to each other. As such, different sizes of shoes can be covered by the shoe cover by adjusting the fastening range between the two ends of the rear cover sheet 11.
  • Referring to FIG. 7, a schematic diagram of the bottomless rainproof shoe cover 1 capable of being put on and taken off rapidly when being put onto a shoe 14 and a leg 15 according to an embodiment of the present invention is shown therein. The front cover 10 covers the shoe 14 at a front portion, the framing strip 12 goes along the front-most portion of the shoe 14, the fixture 13 is located along the shoe side positions, and the rear cover sheet 11 covers the shoe heel, and the leg 15 of the user. Therefore, the bottomless rainproof shoe cover 1 provides good protection from rainwater as well as convenience in terms of being put on and taken off.
  • It is to be understand that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
