Description:

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a cover, and more particularly to a non-slip shoe cover that can allow a user walk on multiple slippery conditions conveniently.

2. Description of the Related Art

When people walk on ice or snow to view the scenery or go out to work in winter with conventional shoes, they will slip or slide easily because the conventional shoes can not provide enough friction. If people slip on the ground heavily and are not lucky enough, they may break their arm or leg or even suffer more serious injuries. Furthermore, when people are engaged in sports or recreational activities like golf or fishing, the conventional shoes can not provide enough adhesion to cause people losing balance and getting hurt easily. However, preparing special shoes for slippery conditions and sports are expensive for people. Changing different shoes is also time wasting and troublesome.

To overcome the shortcomings, the present invention provides a non-slip shoe cover to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a non-slip shoe cover that can allow a user walk on multiple slippery conditions conveniently.

A non-slip shoe cover in accordance with the present invention comprises a body, a toe cap and a holding member. The body comprises a sole, multiple protrusions and multiple studs. The sole has a bottom, a front section, a rear section and a cutout defined between the front section and the rear section. The protrusions are formed integrally on the front section and the rear section of the sole and protrude out from the bottom of the sole. The studs are mounted on the front section and the rear section of the sole and protrude out from the bottom of the sole. The toe cap is formed integrally on the front section of the sole. The holding member is formed integrally on the rear section of the sole.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1 to 5, a non-slip shoe cover in accordance with the present invention comprises a body (10), a toe cap (20) and a holding member (30, 30A).

The body (10) is made of elastic materials and comprises a sole (11), multiple protrusions (12) and multiple studs (13) and may comprise multiple spikes (14). The sole (11) is disposed under the bottom of a shoe and has a bottom, a front section, a rear section and a cutout (111, 111A). The cutout (111, 111A) is defined between the front section and the rear section to reduce the weight of the non-slip shoe cover, may be substantially rectangular or triangular and has a width. When the cutout (111A) is triangular, the width of the cutout (111A) tapers toward the front section of the sole (11).

The protrusions (12) are conical, are formed integrally on the front section and the rear section of the sole (11) and protrude out from the bottom of the sole (11) to increase the friction of the bottom of the sole (11). The protrusions (12) on the front section of the sole (11) are divided into four groups and two of the groups are formed longitudinally and other two groups are formed transversely between the two longitudinal groups. The protrusions (12) on the rear section of the sole (11) may be divided into three groups and two of the groups are formed transversely near the cutout (111) and the other group is formed far away the cutout (111, 111A) relative to and between the two transverse groups.

The studs (13) are mounted on the front section and the rear section of the sole (11), protrude out from the bottom of the sole (11) and can increase friction of the bottom of the sole (11). The studs (13) on the front section may have a number of five and are disposed between the four groups of protrusions (12) on the front section of the sole (11). The studs (13) on the rear section may have a number of three and are disposed between the three groups of protrusions (12) on the rear section of the sole (1). So the protrusion (12) and the studs (13) are distributed evenly on the front section and the rear section of the sole (11) to provide an improved stableness.

The spikes (14) are mounted respectively on the studs (13) and each spike (14) has a base (141), multiple first ribs (142) and multiple second ribs (143). The base (141) is mounted around one of the studs (13) and has a bottom opposite to the bottom of the sole (11). The first ribs (142) are formed radially on the bottom of the base (141) and each first rib has an inner end and a thickness tapered toward the inner end. The second ribs (143) are formed radially on the bottom of the base (141) and each second rib (143) is disposed between adjacent first ribs (142) and has an inner end, an outer end, a bottom surface, a width, a thickness, at least one groove (1431) and a block (1432). The width and thickness of the second rib (143) tapers toward the inner end of the second rib (143). The at least one groove (1431) is defined in the outer end and the bottom surface of the second rib (143). The block (1432) is formed on the bottom surface of the second rib (143). With the first ribs (142) and the second ribs (143) formed on the bottom of the base (141), the spikes (14) mounted on the bottom of the sole (11) can improve adhesion of the non-slip shoe cover.

The toe cap (20) is formed integrally on the front section of the sole (11) and extends over the front portion of the sole (11) to hold the non-slip shoe cover on the shoe in position.

The holding member (30) is formed integrally on the rear section of the sole (11), is attached to the rear portion of the shoe to hold the shoe in the non-slip shoe cover in cooperation with the toe cap (20), has a strap (31) or a heel cap (31A) and a tab (32) and may have a connector (33). The strap (31) is formed integrally on and extends over the rear section of the sole (11) and has a front edge and a rear edge. The heel cap (31A) is formed integrally on and extends over the rear section of the sole (11) to cover the heel of the shoe and has a front edge. The tab (32) is formed integrally on the front edge of the strap (31) and the heel cap (31A) and has a top surface and multiple projections (321) formed integrally on the top surface to facilitate gripping the tab (32). The at least one connector (33) is formed on the rear edge of the strap (31) and is connected to the rear section of the sole (11) to fasten the strap (31) securely.

When the non-slip shoe cover is mounted on the shoe (40), the user can walk on slippery conditions such as ice or snow without slipping. When the user is engaged in sports or recreational activities such as golf and fishing, the non-slip shoe cover can provide enough adhesion and prevent the user from losing his or her balance. In addition, the user can conveniently render his or her shoe non-slip and needs not to prepare special shoes such as snowshoe or golf shoe to save the user's expense and time. So the non-slip shoe cover is suitable for multiple slippery conditions and can conveniently provide adhesion and friction for shoes.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
