When the bar is engaged, it may be rotated in a clockwise direction opposite to the rotation direction of the driving gear unit 173 .

Here, the skipping rope 200 starts to be wound along the line receiving groove 131 of the winding rod 130 when the first gear unit 171 rotates in any one of the clockwise and counterclockwise directions. and, when the first gear unit 171 rotates in the other one of the clockwise and counterclockwise directions, it starts to be unwound from the line receiving groove 131 of the winding rod 130 .

Therefore, it is preferable that the spiral direction of the string receiving groove 130 formed in the winding rod 130 is processed in a direction corresponding to the above-described winding and unwinding design.

In addition, the line guide unit 160 is, when the second gear unit 171 rotates in any one of the clockwise and counterclockwise directions, the winding start position along the guide rod 150 (the left side in the drawing in FIG. 2 ). reference) to the winding completion position (refer to the right side of the drawing in FIG. 2), and on the contrary, when the second gear unit 171 rotates in the other one of the clockwise and counterclockwise directions, along the guide rod 150 It can be moved from the winding-up completion position to the winding-up start position.

Therefore, the spiral direction of the male thread 141 formed on the outer circumferential surface of the guide rod 150 is preferably processed in a direction corresponding to the winding and unwinding design of the skipping rope 200 described above.

Meanwhile, the clutch unit 190 controls the rotational power of the gear set 170 of the motor driving unit 180 .

In more detail, the clutch unit 190 includes a first clutch plate 190a connected to a rotation shaft of the motor driving unit 180 and a second clutch plate 190b connected to a shaft 173a of the driving gear unit 173 . ), and the rotational power of the motor driving unit 180 may be transmitted or blocked (ie, intermittent) by the mating or separation between the first clutch plate 190a and the second clutch plate 190b.

Here, the clutch unit 190 is an end of the motor driving unit 180 , and the first clutch plate 190a and the second clutch unit by a user push operation of the switching unit 195 exposed to the outside of the handle unit 100 . The plates 190b may be provided to be mated to each other, and the first clutch plate 190a and the second clutch plate 190b may be separated from each other by a user's push release operation.

Therefore, when the user pushes the switching unit 195 to accommodate the winding and storage of the skipping rope 200, the first clutch plate 190a and the second clutch plate 190b of the clutch unit 190 are combined with each other. The rotational power of the motor driving unit 180 is transmitted to the driving gear unit 173 , and the first gear unit 171 and the second gear unit 172 meshed with the driving gear unit 173 are simultaneously rotated while winding. The guide unit 160 for rotating the rod 130 and the spiral rod 140 may be moved in a straight line from the winding start position to the winding completion position.

When the user releases the push operation of the switching unit 195, the rotation power of the motor driving unit 180 is blocked by the clutch unit 190, so the user uses the length of the skipping rope 200 according to the stop position. The length of the skipping rope 200 may be further adjusted by performing a jumping rope exercise or manually pulling the rope. At this time, since the first gear unit 171 and the second gear unit 172 are still engaged at the same time by the driving gear unit 173 , the line guide unit 160 by the length of the skipping rope 200 is unwound. It is natural to linearly move according to the axial rotation of the spiral rod 140 from the winding completion position to the winding start position.

5 is a cross-sectional view showing a specific operation state of the line guide part of the configuration of FIG.

In the jumping rope exercise mechanism according to an embodiment of the present invention, the rope winding means 120 includes a rope 200 for skipping rope, a spiral rod 140 and a guide rod 150, as shown in FIG. 5 . It is provided in the inner space (110S) of the handle case 110 so as to penetrate each, and further includes a line guide part 160 reciprocating in the longitudinal direction of the inner space (110S) according to the amount of rotation of the spiral rod 140. can

The line guide unit 160 serves to assist in winding the skipping rope 200 on the outer circumferential surface of the winding rod 130 so as not to overlap each other, as described above. The inner space 110S of the handle case 110 provides only a relatively slim space in which the skipping rope 200 is wound and accommodated while having a diameter that can be gripped by the user's hand, and the line guide part 160 ) is a very important configuration for uniform winding of the skipping rope 200 wound on the outer peripheral surface of the winding rod 130 .

More specifically, in the line guide unit 160, as shown in FIG. 5, a line seating part 161 for receiving and clamping the skipping rope 200 may be formed in the form of a groove with one end open. there is.

A clamping release unit 166 may be slidably provided with respect to the guide slit 163 in an opened portion of the line guide unit 160 where the line seating unit 161 is formed. The clamping release unit 166 closes at least an opened portion of the rope seating part 161 to prevent the skipping rope 200 from arbitrarily leaving the rope seating part 161 to the outside. In addition, the clamping release unit 166 completely opens the rope seating part 161 to one side to forcibly release the skipping rope 200 to adjust the length when the user adjusts the length of the jumping rope from the rope seating part 161. (200) serves to temporarily separate.

Such a clamping release unit 166 is, as shown in FIG. 2 , in the handle case 110 at the starting position of winding the line guide unit 160 and the winding completion position of the line guide unit 160, respectively, in the handle case ( Due to the operation door 115 provided to expose the inner space 110S of 110 , the user can open and close the operation using the operation end 167 with a finger.

In addition, in the line guide unit 160, the spiral rod 140 penetrates, and the spiral rod through hole ( 164) and a guide rod through hole 165 provided to pass through the guide rod 150 may be further formed.

A brief description of the operation process of the jumping rope exercise device according to an embodiment of the present invention configured as described above is as follows.

First, the winding and receiving process of the handle part 100 of the skipping rope 200 will be described. When the user pushes the switching part 195 , the clutch part 190 rotates the motor driving part 180 . Power is transmitted to the driving gear unit 173 , and the first gear unit 171 and the second gear unit 172 simultaneously meshed with the driving gear unit 173 are simultaneously rotated in the winding direction.

At this time, according to the rotation of the second gear unit 172 , the spiral rod 140 linearly moves the line guide unit 160 in the winding direction, and is clamped to the line seating unit 161 of the line guide unit 160 . The winding is completed at the winding completion position as the rope 200 for skipping is sequentially received and wound in the rope receiving groove 131 of the winding rod 130 .

The automatic unwinding process of the skipping rope 200 suffices to be understood as the opposite operation of the above winding process in that the motor driving unit 180 driven to rotate in the opposite direction is used as it is.

On the other hand, when the user wants to manually untie the rope 200 for skipping in the handle portion 100 while being wound and accommodated, the guide portion 160 for opening the operation door 115 corresponding to the winding completion position. After the clamping release unit 166 slides to completely open the line seating portion 161, the skipping rope 200 is separated from the line seating portion 161, and the rope outside the handle 100 is forcibly moved. You can release the rope 200 for skipping by pulling it or adjust its length.

After that, the operation door 115 corresponding to the winding start position is opened for automatic winding reception by the motor driving unit 180, and then the rope 200 for skipping the rope 200 is attached to the rope seat part 161 of the rope guide part 160. ), and then, by using the clamping release unit 166, the skipping rope 200 may be operated in advance so as not to be separated from the rope seating portion 161.

As such, the jumping rope exercise device according to an embodiment of the present invention provides the advantage of automatically winding and storing the skipping rope 200 inside the handle portion 100 using the rope winding means 120 . .

Above, the jumping rope exercise mechanism according to an embodiment of the present invention has been described in detail with reference to the accompanying drawings. However, the embodiment of the present invention is not necessarily limited by the above-described embodiment, and it is natural that various modifications and implementations within an equivalent range are possible by those skilled in the art to which the present invention pertains. will be. Therefore, the true scope of the present invention will be determined by the claims to be described later.
