1 to 3, in the sports jumping device according to this embodiment, the shoe 150 is coupled to the body 100 extending along one direction, and from one side of the body 100 to the downward direction inside the space. is extended to form, the first wheel 230 is coupled to one side, and the first support part 200 that is bent when a load is applied, is inserted into the space of the first support part 200 to provide elasticity to the first support part 200 It provides an elastic body 300, and extends downward from the other side of the main body 100, and includes a second support part 400 to which a second wheel 430 is coupled to one side.

The main body 100 serves to support the first and second supporting parts 200 and 400 , and may be coupled to the bottom of the shoe 150 . Here, the body 100 may be formed in a plate shape extending along one direction. At this time, a plurality of fastening holes 110 are formed in the main body 100 , and fastening means 120 such as bolts and nuts are fastened to the fastening holes 110 to be coupled to the bottom of the shoe 150 ( FIG. 1 ). to Figure 2). In addition, the main body 100 may be formed to have a wide width at one side (front) on which the ball of the foot is disposed so as to correspond to the shape of the shoe 150 .

The first support part 200 serves to provide elasticity to the wearer, and extends from one side (front) of the main body 100 to a downward direction to form a space therein. That is, the first support part 200 may be formed in a closed loop shape in the downward direction of one side (front) of the main body 100 . The first support part 200 is formed in a plate shape and may be bent when a load is applied thereto. For example, when a load is applied to the first support part 200 when the wearer jumps, the first support part 200 may be bent to provide elasticity to the wearer. In addition, even when the wearer lands after jumping, the first support part 200 is bent and shock can be absorbed.

Specifically, the first support part 200 may include a first elastic part 210 and a second elastic part 220 . Here, the first elastic part 210 may extend downwardly from one end (front end) of the body 100 in a curved surface having a predetermined radius of curvature R1 (see FIG. 3 ). In this case, the first elastic part 210 may protrude in the opposite direction of the second support part 400 . For example, the first elastic part 210 may be formed in a semicircular shape when viewed with respect to a longitudinal cross-section. In addition, the second elastic part 220 may extend from the end (lower end) of the first elastic part 210 to the lower surface of the main body 100 . In this case, as the second elastic part 220 extends from the distal end (lower end) of the first elastic part 210 to the lower surface of the main body 100 , the second elastic part 220 may be closer to the lower surface of the main body 100 . In addition, the second elastic part 220 may extend in a convexly curved surface in a direction away from the main body 100 . As described above, since the first elastic part 210 is formed in a semi-circular shape and the second elastic part 220 extends in a convexly curved surface, when a load is applied, the first elastic part 210 has a reduced radius of curvature. The second elastic part 220 may be bent to be closer to the main body 100 (see FIGS. 3 to 4 ). As such, by bending the first and second elastic parts 210 and 220, the wearer can provide elasticity when jumping or absorb shock when landing after jumping.

Meanwhile, the thickness of the first support part 200 including the first and second elastic parts 210 and 220 may be thinner than the thickness of the main body 100 . As such, since the thickness of the first support part 200 is thinner than the thickness of the body 100, the first support part 200 can be bent relatively easily and thus can effectively provide elasticity or absorb shock.

Additionally, as shown in FIG. 2 , a first wheel 230 may be coupled to one side of the first support unit 200 . Here, a first coupling hole 231 may be formed on one side of the first support unit 200 , and a first rotation shaft 233 to which the first wheel 230 is coupled is inserted into the first coupling hole 231 . can be In this case, one side of the first support part 200 to which the first wheel 230 is coupled may be a region where the first elastic part 210 and the second elastic part 220 meet.

The elastic body 300 serves to provide elasticity to the first support part 200 , and may be inserted into the inner space of the first support part 200 having a closed loop shape. As shown in FIG. 3 , since the first elastic part 210 extends to a curved surface having a predetermined radius of curvature R1 , the elastic body 300 has an outer surface corresponding to the first elastic part 210 with a predetermined radius of curvature ( R1) may include a curved surface. For example, when the first elastic part 210 is formed in a semi-circular shape with respect to the longitudinal cross-section, the elastic body 300 may be formed in a cylindrical shape to correspond to the first elastic part 210 . Accordingly, the elastic body 300 may be in contact with the inner surface of the first elastic part 210 in a cylindrical region disposed at the front. Here, when a load is applied, as described above, the first support part 200 is bent (in particular, the first elastic part 210 is bent), and the elastic body 300 is deformed (compressed in the vertical direction, FIG. 3 ). to FIG. 4). At this time, elasticity to return to the original shape is generated in the elastic body 300 , and such elasticity is provided to the first support part 200 . Therefore, when the wearer applies a load to the first support part 200 when jumping, the first support part 200 is bent, and the elastic body 300 is deformed, so that elasticity can be more effectively provided to the wearer. In addition, even when the wearer lands after jumping, the first support part 200 is bent, and the elastic body 300 is deformed to more effectively absorb the impact.

Meanwhile, as shown in FIGS. 1 to 2 , the length of the elastic body 300 may correspond to the width of the first elastic part 210 . In this case, the elastic body 300 may be in contact with the first elastic part 210 in the entire width direction of the first elastic part 210 . Accordingly, since the elastic body 300 provides elasticity to all parts of the first elastic part 210 , even if the load is biased toward the left or right side of the main body 100 , the elastic body 300 stably maintains the first elastic part 210 . ) can provide elasticity. Here, the material of the elastic body 300 is not particularly limited, but may be, for example, urethane or silicone.

Additionally, a through hole 310 may be formed in the elastic body 300 in the longitudinal direction of the elastic body 300 . Here, the through hole 310 may extend along the longitudinal center of the elastic body 300 . In addition, auxiliary through-holes 320 are formed in the elastic body 300 in the longitudinal direction of the elastic body 300 . In this case, a plurality of auxiliary through-holes 320 may be formed to surround the through-holes 310 . For example, four auxiliary through-holes 320 may be disposed radially from the longitudinal center of the elastic body 300 , and the four auxiliary through-holes 320 are at the same distance from the longitudinal center of the elastic body 300 . is disposed, and may be disposed at the same angle (90°) with respect to the longitudinal center of the elastic body 300 . More specifically, an imaginary line connecting the centers of the two auxiliary through-holes 320 disposed on the upper side of the four auxiliary through-holes 320 and the two auxiliary through-holes disposed on the lower side of the four auxiliary through-holes 320 . An imaginary line connecting the centers of the holes 320 may be parallel to the extension direction of the body 100 . In this case, the load acting on the elastic body 300 may be evenly distributed to the four auxiliary through-holes 320 . The above-described through-hole 310 and auxiliary through-hole 320 may induce the elastic body 300 to be more easily deformed, thereby strengthening the elasticity of the elastic body 300 .

Meanwhile, a protrusion 330 protruding in the direction of the elastic body 300 may be formed on the first support part 200 and the main body 100 . In this case, the protrusion 330 may extend in the width direction of the first support 200 and the main body 100 . In addition, a depression 340 into which the protrusion 330 is inserted may be formed on the outer surface of the elastic body 300 . In this case, the depression 340 may extend in the longitudinal direction of the elastic body 300 . That is, the first support 200 and the protrusion 330 formed in the main body 100 are inserted into the depression 340 formed in the elastic body 300 , and accordingly, the elastic body 300 is the first support portion 200 of the first support portion 200 . It can be fixed in the interior space. Specifically, the protrusion 330 may include a first protrusion 331 protruding from the lower surface of the main body 100 , and second and third protrusions 333 and 335 protruding from the inner surface of the first support unit 200 . have. In this case, the first, second, and third protrusions 331 , 333 , and 335 may be disposed at the same angle (90°). In this way, since the plurality of protrusions 330 are inserted into the plurality of recessed portions 340 , the elastic body 300 does not rotate and deforms on the spot even when a load is applied to provide elasticity.

The second support part 400 serves to support the second wheel 430 , and extends downwardly from the other side (rear side) of the main body 100 so that a space is formed therein. That is, the second support part 400 may be formed in a closed loop shape in the lower direction of the other side (rear side) of the main body 100 . The second support 400 is formed in a plate shape and may be bent when a load is applied thereto. For example, when a load is applied to the second support part 400 when the wearer lands after jumping, the second support part 400 is bent to absorb the shock.

Specifically, the second support part 400 may include a third elastic part 410 and a fourth elastic part 420 . Here, the third elastic part 410 may extend downwardly from the other end (rear end) of the main body 100 in a curved surface. In this case, the third elastic part 410 may extend in a direction away from the first support part 200 . Accordingly, the end (lower end) of the third elastic part 410 may protrude further rearward than the other end (rear end) of the main body 100 . In addition, the fourth elastic part 420 may extend from the distal end (lower end) of the third elastic part 410 to the lower surface of the main body 100 in a curved surface. In this case, the fourth elastic part 420 may extend in a direction closer to the first support part 200 . Since these third and fourth elastic parts 410 and 420 extend in a curved surface, when a load is applied, the third and fourth elastic parts 410 and 420 are bent, so that the wearer can absorb shock when landing after jumping. (See Fig. 5).

Meanwhile, the thickness of the second support part 400 including the third and fourth elastic parts 410 and 420 may be thinner than the thickness of the main body 100 . As such, since the thickness of the second support part 400 is thinner than the thickness of the main body 100 , the second support part 400 may be bent relatively easily, thereby effectively absorbing the impact.

Additionally, as shown in FIG. 2 , a second wheel 430 may be coupled to one side of the second support 400 . Here, a second coupling hole 431 may be formed on one side of the second support 400 , and a second rotation shaft 433 to which the second wheel 430 is coupled is inserted into the second coupling hole 431 . can be At this time, one side of the second support part 400 to which the second wheel 430 is coupled is a region where the third elastic part 410 and the fourth elastic part 420 meet (that is, the end of the third elastic part 410 ). (bottom)). On the other hand, since the end (lower end) of the third elastic part 410 protrudes more rearward than the other end (rear end) of the main body 100 , the second wheel 430 is disposed at the rear of the main body 100 . Therefore, since the distance between the first wheel 230 and the second wheel 430 is wider than the length of the main body 100 , the first and second wheels 230 and 430 can stably support the main body 100 . have.

As shown in FIG. 3 , the body 100 and the first and second support parts 200 and 400 have first, second, third, fourth and fifth protrusions 510, 520, 530, 540, 550 to increase rigidity. ) can be formed. Specifically, a first protrusion 510 protruding to extend in one direction may be formed on a lower surface of the main body 100 facing the second elastic part 220 . In addition, on the inner surface (upper surface) of the second elastic part 220 facing the lower surface of the body 100, a second protrusion 520 protruding to extend in the extending direction of the second elastic part 220 may be formed. can In this case, the second protrusion 520 may continuously extend from the first protrusion 510 . In addition, the third protrusion 530 may be formed on the outer surface (lower surface) of the second elastic part 220 to extend in the extending direction of the second elastic part 220 . The rigidity of the main body 100 and the first support part 200 may be increased by the first, second, and third protrusions 510 , 520 , and 530 . On the other hand, a fourth protrusion 540 protruding to extend in a direction in which the third elastic part 410 is extended is formed on the outer surface of the third elastic part 410 , and the fourth protrusion part 540 is formed on the outer surface of the fourth elastic part 420 . 4 A fifth protrusion 550 protruding to extend along the extending direction of the elastic part 420 may be formed. The rigidity of the second support part 400 may be increased by the fourth and fifth protrusions 540 and 550 .

The above-described body 100 and the first and second support portions 200 and 400 may be integrally formed. At this time, the material of the main body 100 and the first and second support parts 200 and 400 is not particularly limited, but for example, PC (Poly Carbonate), ABS (Acrylonitrile Butadiene Styrene), PP (Poly Propylene), or nylon (nylon) and the like.
