Description:

FIELD OF THE INVENTION

The present invention relates to roller shoes (inline skate type roller skates), and more particularly, to roller shoes in which a roller can be easily detachably mounted on an outsole thereof, while minimizing the thickness of an outsole.

BACKGROUND OF THE INVENTION

Roller skates as generally known have a plurality of rollers mounted in two rows or one row in forward and backward directions on an outsole. Among them, especially, inline skate type roller skates having the rollers mounted in one row provide good speeds and various skating techniques, and thus, they are very popular to a lot of peoples.

Since the inline skate type roller skates have the rollers fixedly mounted on the outsoles, however, they cannot be used as general shoes.

Unlike the typical roller skates as widely known conventionally, recently, there are proposed improved roller skates having a roller mounted on the heel portion thereof.

Since the roller is detachably mounted on the improved roller skates, both of walking and skating can be provided to a wearer, thereby giving lots of pleasures to the wearers. As only a single roller is mounted on the heel portion of each shoe, however, it is difficult for a beginner wearer to maintain the balancing during the skating, which causes a number of safety problems.

On the other hand, a variety of inline type skate roller skates having the rollers detachably mounted thereon have been proposed and marketed. But since they have the shaft formed integrally with the rollers in such a manner as to be separated from the skates, a fixing body adapted to hold the shaft is disposed inside the outsole. In this structure, the fixing body disposed on the outsole has a larger thickness than the center of the roller, and therefore, if the roller is mounted on the front portion of the outsole of the skate, the outsole becomes excessively thick, thereby making the wearer feel inconvenient upon walking.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide roller shoes in which a roller can be easily detachably mounted on an outsole thereof, while minimizing the thickness of an outsole.

To accomplish the above object, according to the present invention, there is provided a roller shoe having a roller mounted on the front and back portions of an outsole, the roller shoe including: a fixing body insertedly fixed on the outsole, the fixing body having an insertion hole opened downwardly therefrom and a plurality of guide protrusions formed axially on the inner lateral wall of the insertion hole; a roller-fixing member and an auxiliary outsole which are selectively fitted to the insertion hole of the fixing body, the roller-fixing member having the roller coupled to the lower portion thereof, and the roller-fixing member and the auxiliary outsole each having a plurality of guide grooves formed on the outer peripheral surface thereof so as to allow the plurality of guide protrusions of the fixing body to be fitted thereinto; and fixing means adapted to fix the roller-fixing member and the auxiliary outsole selectively fixed insertedly to the fixing body.

The fixing means includes a permanent magnet embedded on the bottom surface of the insertion hole of the fixing body and a magnetic substance insertedly fixed to the roller-fixing member and the auxiliary outsole in such a manner as to be attached to the permanent magnet.

Alternatively, the fixing means includes locking holes formed at the opposing positions to each other along the inner lateral wall of the insertion hole of the fixing body and elastic locking pieces each having a locking projection formed on the roller-fixing member and the auxiliary outsole in such a manner as to be correspondingly locked to the locking holes.

According to the present invention, the outsole of the roller shoe has a plurality of separation grooves formed thereon in such a manner as to abut against the outer periphery of the fixing body, and the auxiliary outsole has a plurality of grips formed along the outer periphery thereof and adapted to be inserted correspondingly into the plurality of separation grooves.

According to the present invention, first, the roller-fixing member to which the roller is coupled and the auxiliary outsole are fitted to the insertion hole of the fixing body adapted to be insertedly fitted to the outsole of the shoe and are thus fixed to the fixing body by means of a magnetic force, thereby allowing the mounting and demounting to be easily conducted.

Secondly, after the roller-fixing member to which the roller is coupled and the auxiliary outsole are fitted to the insertion hole of the fixing body adapted to be insertedly fitted to the outsole of the shoe, the elastic locking pieces formed on each of the roller-fixing member and the auxiliary outsole and the locking holes formed on the insertion hole are coupled correspondingly to each other, thereby allowing the mounting and demounting to be easily conducted.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, an explanation on a roller shoe according to the preferred embodiments of the present invention will be given with reference to the attached drawings.

FIG. 1 is a bottom perspective view showing roller shoes according to a first embodiment of the present invention, FIGS. 2a and 2b are sectional views showing the main parts of the roller shoes according to the first embodiment of the present invention, wherein FIG. 2a shows the state where a roller-fixing member is removed from the shoe and FIG. 2b shows the state where the roller-fixing member is coupled to the shoe, and FIGS. 3a and 3b are sectional views showing the main parts of the roller shoes according to the first embodiment of the present invention, wherein FIG. 3a shows the state where an auxiliary outsole is coupled to the shoe and FIG. 3b shows the state where the auxiliary outsole is removed from the shoe.

As shown, there is provided a roller shoe 1 having a roller 3 mounted on the front and back portions of an outsole 2, the roller shoe 1 including: a fixing body 10 insertedly fixed on the outsole 2; and a roller-fixing member 20 and an auxiliary outsole 30 which are selectively fitted to the fixing body 10, the roller-fixing member 20 having the roller 3 coupled to the lower portion thereof.

According to the first embodiment of the present invention, the roller shoe 1 includes: the fixing body 10 insertedly fixed on the outsole 2 made of an EVA resin material and having a base plate 2a made of a rubber material attached thereon, the fixing body 10 having an insertion hole 11 opened downwardly therefrom; and the roller-fixing member 20 and the auxiliary outsole 30 selectively fitted to the fixing body 10.

The roller-fixing member 20 that is selectively fitted to the insertion hole 11 of the fixing body 10 has the roller 3 separably coupled to the lower portion thereof. The roller 3 is coupled in such a manner that the shaft integrally formed to the roller 3 is forcedly pressed-fitted to a bracket 21 formed on the roller-fixing member 20, which is a general technique in this field.

Fixing means 40 for the roller-fixing member 20 and the auxiliary outsole 30 selectively fitted to the fixing body 10 includes a permanent magnet 41 embedded on the bottom surface of the insertion hole 11 of the fixing body 10 and a magnetic substance 42 insertedly fixed to the roller-fixing member 20 and the auxiliary outsole 30 in such a manner as to be attached to the permanent magnet 41.

When the roller-fixing member 20 and the auxiliary outsole 30 are inserted into the insertion hole 11, thus, the magnetic substance 42 is attached to the permanent magnet 41 by means of a strong magnetic force generated from the permanent magnet 41, thereby maintaining the firmly attaching state.

Further, the roller-fixing member 20 and the auxiliary outsole 30 should be maintained in their directions, without any rotation, in the state where they are inserted into the insertion hole 11, and according to the present invention, therefore, a plurality of guide protrusions 12 are formed in an axial direction on the inner lateral wall of the insertion hole 11 and a plurality of guide grooves 22 and 32 are formed on the roller-fixing member 20 and the auxiliary outsole 30 so as to correspondingly insert the guide protrusions 12 thereinto, such that in the state where the roller-fixing member 20 and the auxiliary outsole 30 are inserted into the insertion hole 11, they can be rigidly fixed thereto, without any rotation.

Even if not shown, it is of course possible that the guide grooves may be formed on the inner lateral wall of the insertion hole 11 and the guide protrusions may be formed on the roller-fixing member 20 and the auxiliary outsole 30.

In the above-mentioned structure, the roller-fixing member 20 is easily removed from the fixing body 10 by pulling the roller 3 or the protruded bracket 21 to which the roller 3 is fixed. However, it is very hard to remove the auxiliary outsole 30 from the fixing body 10, without any separate means.

In order to solve this problem, thus, the outsole 2 of the roller shoe 1 has a plurality of separating grooves 4 formed thereon in such a manner as to abut against the outer periphery of the fixing body 10, and the auxiliary outsole 30 has a plurality of grips 33 formed along the outer periphery thereof and adapted to be inserted correspondingly into the separating grooves 4.

At this time, the grips 33 have a smaller size than the separating grooves 4 so as to be disposed inside the separating grooves 4.

FIG. 4 is a bottom perspective view showing roller shoes according to a second embodiment of the present invention, FIGS. 5a and 5b are sectional views showing the main parts of the roller shoes according to the second embodiment of the present invention, wherein FIG. 5a shows the state where a roller-fixing member is coupled to the shoe and FIG. 5b shows the state where the roller-fixing member is removed from the shoe, and FIGS. 6a and 6b are sectional views showing the main parts of the roller shoes according to the second embodiment of the present invention, wherein FIG. 6a shows the state where the auxiliary outsole is coupled to the shoe and FIG. 6b shows the state where the auxiliary outsole is removed from the shoe.

According to the second embodiment of the present invention, the roller shoe 1 includes: the fixing body 10 insertedly fixed on the outsole 2 and having the insertion hole 11 opened downwardly therefrom; and the roller-fixing member 20 and the auxiliary outsole 30 selectively fitted to the fixing body 10, the roller-fixing member 20 having the roller 3 separably coupled to the lower portion thereof.

Fixing means 40 for the roller-fixing member 20 and the auxiliary outsole 30 selectively fitted to the fixing body 10 includes: locking holes 43 formed at the opposing positions to each other along the inner lateral wall of the insertion hole 11 of the fixing body 10; and elastic locking pieces 44 each having a locking projection 45 formed on the roller-fixing member 20 and the auxiliary outsole 30 in such a manner as to be correspondingly locked to the locking holes 43.

The elastic locking pieces 44 are fixed at one ends thereof to the roller-fixing member 20 and the auxiliary outsole 30, and thus, when the elastic locking pieces 44 are pressurized, they are moved at the end portion where the locking projection 45 is formed toward the roller-fixing member 20 and the auxiliary outsole 30. If the pressurizing force against the elastic locking pieces 44 is removed, the end portions where the locking projections 45 are formed on the elastic locking pieces 44 are moved to the outsides of the roller-fixing member 20 and the auxiliary outsole 30 and are thus inserted into the locking holes 43.

In order to rigidly maintain the inserted state of the roller-fixing member 20 and the auxiliary outsole 30 into the insertion hole 11, like the first embodiment of the present invention, the guide protrusions 12 are formed in an axial direction on the inner lateral wall of the insertion hole 11, and the guide grooves 22 and 32 are formed on the roller-fixing member 20 and the auxiliary outsole 30 so as to correspondingly insert the guide protrusions 12 thereinto.

In the above-mentioned structure, the elastic locking pieces 44 formed along the outer periphery of the roller-fixing member 20 are fixed at one ends thereof to the protruded bracket 21 to which the roller 3 is fixed, such that the roller-fixing member 20 is easily removed from the fixing body 10. However, it is very hard to remove the auxiliary outsole 30 from the fixing body 10, without any separate means. In order to solve this problem, thus, the outsole 2 of the roller shoe 1 has the separating grooves 4 formed thereon in such a manner as to abut against the outer periphery of the fixing body 10, and each elastic locking piece 44 formed on the auxiliary outsole 30 is exposed partially through the separating groove 4, such that when the elastic locking pieces 44 are pressurized, the auxiliary outsole 30 can be easily separated from the fixing body 10.

According to the first and second embodiments of the present invention, the roller-fixing member 20 and the auxiliary outsole 30, which are selectively inserted into the fixing body 10 insertedly fixed to the outsole 2, are easily removed from the fixing body 10, such that since the roller shoe 1 is rapidly converted into a general shoe, no separate purchase for the general shoes is needed, thereby obtaining economical saving.

As described above, there is provided the roller shoe that is capable of greatly reducing the thickness of the outsole by the insertion of the fixing body into the outsole and easily mounting removably the roll-fixing member and the auxiliary outsole onto the fixing body so as to be rapidly converted into a general shoe, which does not need any separate purchase for the general shoes, thereby obtaining economical saving.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
