Description

FIELD OF THE INVENTION

The present invention relates to shoe devices, and more particularly, to a shoe device, which provides various uses, and has economical and convenient properties.

BACKGROUND OF THE INVENTION

Shoes are one of the necessities for doing sports. Wearing a pair of shoes specially designed for a particular sport helps a person do the sport more smoothly, for example, roller skates or skates are required for skating. As such, however, problems are generated, for example, it is quite troubling to purchase, store and carry quite a few pairs of shoes required for doing various sports. In addition, people normally can not afford to buy all of the shoes for different uses.

SUMMARY OF THE INVENTION

It is therefore an objective of the present invention to provide a shoe device with a coupling plate and a fixing member being removably mounted thereon, such that different uses of the shoe device can be alternated only by removing or mounting the binding plate and the fixing member, so as to provide economical purchase and convenience for usage, carriage and storage thereof.

In order to achieve the foregoing and other objectives, the invention proposes a shoe device comprising:

a shoe body having at least a coupling hole formed on a base portion of the shoe body, and an engaging groove formed in a middle portion thereof, which has an opening connecting a side surface of the shoe body and extends along a crosswise direction of the shoe body;

a coupling plate having an upper side attached to the base portion of the shoe body and formed with at least a coupling protrusion being removably coupled to the corresponding coupling hole in the base portion of the shoe body, a middle portion formed with an engaging groove being removably engaged with the engaging groove in the base portion of the shoe body, and a lower side mounted with a sporting device suitably used for various sports; and

a fixing member with a length no longer than the width of the base portion of the shoe body, having an upper side formed with an engaging strip being removably engaged with the engaging groove in the base portion of the shoe body, and a lower side formed with an engaging strip being removably engaged with the engaging groove of the coupling plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 and FIG. 2 , a shoe body 1 has one or more than one coupling holes 11 a , 11 b (two are shown in the drawing) formed on a base portion of the shoe body 1 . The coupling holes 11 a , 11 b consist of inserting holes 12 a , 12 b and coupling grooves 13 a , 13 b , which are connected to and shorter in width than the inserting holes 12 a , 12 b ; the inserting holes 12 a , 12 b and the coupling grooves 13 a , 13 b have openings at the bottom of the shoe body smaller than those at the interior of the shoe body. Moreover, the shoe body 1 has a middle portion formed with a wedge-shaped engaging groove 10 having an opening connecting a side surface of the shoe body and extending along a crosswise direction of the shoe body. Referring to FIG. 3 and FIG. 4 , a coupling plate 2 has an upper side attached to the base portion of the shoe body 1 and formed with one or more than one coupling protrusions 20 a , 20 b (two are shown in the drawing) thereon. The coupling protrusions 20 a , 20 b consist of short pillars 23 a , 23 b fixed on the coupling plate 2 and heads 22 a , 22 b larger in size than the short pillars 23 a , 23 b and fixed on ends of the short pillars 23 a , 23 b ; the heads 22 a , 22 b are smaller in size than the openings of the inserting hole 12 a , 12 b at the bottom of the shoe body, but larger than the openings of the coupling grooves 13 a , 13 b at the bottom of the shoe body. Moreover, the coupling plate 2 has a middle portion formed with an engaging groove 21 used to removably engage with an engaging strip 31 of a fixing member 3 described later. In addition, the coupling plate 2 has a lower side mounted with a sporting device suitably used for various sports (a skate is shown in the drawing).

Referring to FIG. 5 , the fixing member 3 with a length no longer than the width of the shoe body 1 has an upper side formed with an engaging strip 30 being removably engaged with the engaging groove 10 in the base portion of the shoe body 1 , and a lower side formed with the engaging strip 31 being removably engaged with the engaging groove 21 of the coupling plate 2 . Additionally, the fixing member 3 is formed with a hollow deformable auxiliary groove 32 approximately in the central portion along a lengthwise direction of the fixing member 3 .

Referring to FIG. 6 , illustrating an assembled form of the shoe device of the invention (a skate is shown in the drawing), coupling and engagement are assured between the engaging groove 10 in the base portion of the shoe body 1 and the engaging strip 30 of the fixing member 3 and between the engaging groove 21 of the coupling plate 2 and the engaging strip 31 of the fixing member 3 , due to the wedge-shaped structures of the grooves 10 , 21 and the strips 30 , 31 , so as to prevent the decoupling of those structures from occurrence when using the shoes.

As such, when exercising or walking, due to the coordinating arrangement of the coupling plate 2 and the shoe body 1 , the counter force generated against the force produced by the body weight applied to the ground can be eliminated by the deformable auxiliary groove 32 of the fixing member 3 , so as to achieve a shock-resistant effect.

FIG. 7 illustrates one embodiment of the shoe device of the invention, wherein the shoe is a roller skate for skating.

FIG. 8 illustrates another embodiment of the shoe device of the invention, wherein the shoes are in-line skates for skating.

FIG. 9 illustrates still another embodiment of the shoe device of the invention, wherein the shoe is a spike for track and field.

FIG. 10 illustrates a further embodiment of the shoe device of the invention, wherein the shoe is an anti-slippery shoe used for resisting the slippage thereof.

FIG. 11 illustrates a further embodiment of the shoe device of the invention, wherein the shoe is a spring-heeled shoe used for decorating the appearance thereof.

FIG. 12 illustrates a further embodiment of the shoe device of the invention, wherein the shoe is a platform shoe used for increasing the height thereof.

FIG. 13 illustrates a further embodiment of the shoe device of the invention, wherein the shoe is directly used as a sports shoe without the coupling plate 2 and the fixing member 3 mounted thereof.

In conclusion, the shoe device of the invention provides various uses, which are alternated only by exchanging the coupling plates 2 for doing different sports, such that it is not necessary to buy quite a few pairs of shoes, and it can save the expense for purchasing the shoes and space for storing the shoes, and thus higher economical and convenient properties are provided. In addition, the shoe device of the invention can reduce the risk for the occurrence of injuries to ankles when wearing the shoes, due to the shock-resistant effect of the deformable auxiliary groove 32 of the fixing member 3 . Meanwhile, the shoe device of the invention can satisfy people who prefer to have a higher height, due to an additional height provided by the coupling plate 2 mounted thereon.

The invention has been described using exemplary preferred embodiments. However, it is to be understood that the scope of the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements. The scope of the claims, therefore, should be accorded the broadest interpretation so as to encompass all such modification and similar arrangements.
