Description

IN-LINE SKATE USING AS A SHOES

Technical Field The present invention relates to an inline skate, and more particularly, to a combined inline skate and shoe that can be used as

running shoes or an inline skate while being folded to wheels assembled to the bottom of the shoe.

Background Art Generally, an inline skate has a frame disposed at the bottom of

a boot type shoe and 3 to 5 wheels disposed in the frame. In such an inline skate, however, the wheels are always exposed. Thus, the

inline skate cannot be used for common shoes, especially on a slope road. Therefore, a user has to carry an additional bag for containing

shoes when the inline skate is not used and then has to change the inline skate or the shoes, if needed. This makes a user inconvenient. Meanwhile, in order to solve the above problem, an inline skate

in which wheels are foldable has been proposed. Examples are Korean Utility Model Registration No.0316651 (entitled "Inline Skate" ),

Korean Utility Model Registration No.0301227 (entitled "Combined

Inline Skate and Shoe" ). However, they have a complicated structure for folding and unfolding the wheels within the shoe. Accordingly,

use of those inline skates may be difficult, the weight and volume can be increased and manufacturing cost is thus increased.

Disclosure of Invention Accordingly, the present invention has been made in view of the

above problems, and it is an object of the present invention to

provide a combined inline skate and shoe in which wheels can be simply

folded into the shoe and the combined inline skate and shoe can be used the shoe or the inline skate, if needed. Another object of the present invention is to provide an inline skate of a relatively simple structure in which the weight and volume are reduced and manufacturing cost is reduced. To achieve the above objects, according to the present invention,

there is provided a combined inline skate and shoe having a structure

in which wheel mounted in the shoe are folded and unfolded, comprising a frame mounted at the bottom of the shoe and having a rectangular

space therein, wherein assembly holes are respectively formed in the

front and rear of the frame, and a first hole and a second hole are formed at a location along which brackets move; the brackets having

holes at the center of both sidewalls, wherein a cylindrical tube is

integrally formed in the brackets in a way to communicate with the

holes, the top of the brackets is rotatably fixed to the assembly hole

of the frame and the bottom of the brackets is fixed to wheels; and an

actuation bar vertically inserted into a hole of the cylindrical tube and having holes at its center, wherein the actuation bar is fixed to the stopper by means of a connection string, wherein the cylindrical tube has the holes at its one side and having the stopper fixed to the

spring inserted into its center.

In the above, a guide groove that forms a circular arc with respect to the rotary shaft is formed within the frame, whereby when

the wheel is folded into the frame, a shaft in which the wheels are assembled is inserted into the guide groove.

Further, the actuation bar has a handle formed at its both sides.

Best Mode for Carrying Out the Invention

The present invention will now be described in detail_, in connection with preferred embodiments with reference to the

aceompanying drawings . FIG. 1 is a perspective view illustrating the construction of a wheel assembly 100 in which a rear wheel assembly unit is separated according to the present invention. The wheel assembly 100 includes a front wheel assembly unit 10a having wheels at the front and a rear wheel assembly unit 10b having wheels at the rear. FIG. 2 is a perspective view showing a state where the wheels are folded. FIG. 3

shows a state where the wheel assembly 100 is mounted at the bottom of

the shoe. FIG. 4 is a cross-sectional view showing a state where the

wheels at one side of wheel assembly 100 are assembled. FIGs. 5a and

5b are exaggerated views of "B" in FIG. 4, for explaining the

operation of the combined inline skate and shoe operates.

Referring to FIG. 1 to FIG. 5, wheels 40 are mounted in brackets

20. The brackets 20 are rotatably mounted at the front and rear of a frame 10 mounted at the bottom of the shoe, thus constituting the front wheel assembly unit 10a and the rear wheel assembly unit 10b. Fixtures for fixing the location of the wheels when they are unfolded and folded are formed in the front wheel assembly unit and the rear

wheel assembly unit, respectively. This will now be described in a more detailer manner. The wheel assembly 100 includes the frame 10 that is mounted at

the bottom of the shoe and has a rectangular space 11, and the brackets 20 having the wheels 40 mounted at the front and rear of the frame 10, thus forming the front wheel assembly unit 10a and the rear

wheel assembly unit 10b. That is, assembly holes 12 are formed in the

front and rear of the frame 10, respectively. The brackets 20 formed by lateral plates 21 are inserted in the assembly holes 12 by means of rotary shafts 24.

Further, the wheels 40 and the shaft 26 are assembled between the lateral plates at the bottom of the brackets 20. Also, holes 22

are formed at the center of the lateral plates 21 of the brackets. In

the above, cylindrical tubes 30 are integrally formed with the lateral plates of the brackets 20. In addition, the wheels are fixed to the

bottom of the brackets 20. The top of the brackets 20 is connected to

the lateral plate 21. In this time, it is preferred that holes are formed even in a portion to which the lateral plates 21 of the

brackets 20 are connected so that an actuation bar to be descried later passes through the holes 32 of the cylindrical tube 30 at the same time. Also, a portion for connecting the lateral plates of the

brackets can vary depending upon a design. Thus, it will not be

described further.

Springs 36 are inserted into both side of the cylindrical tube 30. A connection string 37 is connected between stoppers 38. In

other words, as shown in FIG. 4, the stopper 38 has a hole 39 at the

center. The connection string 37 is inserted into the hole. Meanwhile, the hole 32 penetrates the cylindrical tube in the vertical direction. An actuation bar 34 is inserted into the holes 32 and has a handle 34a

at its both sides. In this time, a hole 35 is formed at the center of the actuation bar. Thus, when the connection string between the

stoppers is connected, the connection string is inserted into the hole.

Meanwhile, a first hole 14 and a second hole 16 are formed in the frame of each of the aforementioned front wheel assembly unit 10a and the rear wheel assembly unit 10b in the downward and inward

direction of the assembly hole 12. Thus, the stoppers are inserted

into the first hole 14 and the second hole 16 to fix the brackets at given locations.

That is, the first holes 14 are formed at both sides at the

bottom of the assembly hole 12 in which the rotary shaft 24 is assembled. Thus, when the brackets 20 in which the wheels are

unfolded, the stoppers 38 are elastically inserted into the first

holes and are fixed to the brackets 20. Also, the second holes 16 are formed in the assembly hole 12 with them spaced apart from the aforementioned first hole by some distance. Thus, the brackets 20 are

folded inwardly, the stoppers 38 are elastically inserted into the

second holes and are fixed to the brackets 20. Next, an actuation bar 34 inserted into the center of the

connection string 37 serves to move the stoppers inwardly in order to

fold an unfolded bracket or unfold a folded bracket. As shown in FIG. 5b, when the actuation bar 34 is rotated, a tension force is generated in the connection string and the stoppers 38 are moved toward the

center. Thereby, the stoppers that are inserted into the first holes 14 or the second holes 16 of the frame can rotate the bracket while being deviated from the frame. Thereafter, if the actuation bar is

released, the stoppers are moved outwardly by means of the springs disposed therein and are then inserted into the second holes 16 or the

first holes 14. At this time, the actuation bar 34 has a handle 34a for holding the bracket at its both sides.

In addition, projections of the shaft 26 in which the wheels are

assembled are inserted into guide grooves 18 formed at the central

front and rear sides of the frame 10. At this time, the guide grooves

18 form a "circular arc with respect to the rotary shaft 25. The operation will be described with reference to FIG. 3. As in the front wheel assembly unit 10a, in order to use the inline skate, the brackets 20 keeps unfolded downwardly and the stoppers 38 are inserted into the first holes 14 formed below the rotary shaft. At this time, the stoppers are pushed toward both sides by means of the spring and are not deviated due to shock, vibration,

and the like. Thereafter, in order to fold the wheels, after the handle at one side among the handle 34a at both sides of the actuation bar 34 is

rotated toward one side, the brackets 20 is rotated and is thus

inserted into the frame, as in the rear wheel assembly unit 10b of FIG.

3. At this time, both ends of the shaft 26 in which the wheels are mounted are moved along the guide groove 18 at both sides of the frame 10 and are then fixed as the stopper 38 widens in the second hole 16.

Industrial Applicability

As described above, a combined inline skate and shoe according to the present invention has a relatively simple structure. Therefore,
