Description

Sub guide for net sports {Serve guide for net sports}

The present invention relates to a sub guide, and more particularly, to a sub guide for net sports for honing sub skills in sports using a net, such as badminter and table tennis.

In sports played by both teams across a net, such as badminter, table tennis, volleyball, foot volleyball, and tennis, the game starts through the serve of one side, and the right to serve is maintained or passed to the team that scores.

The serve is the primary means of obtaining a score. If the opponent makes a serve difficult to receive, the serve itself can score a goal, and the attacking right is maintained by the opponent's defensive action to make it easier to score. be able to get

Therefore, the importance of the serve has recently emerged, and a lot of practice to learn the sub technique is in progress.

However, in the case of conventional serve practice, specifically badminton, for example, in a state where a pair of badminton cocks are inserted at regular intervals on the top of the net, the practice of putting a serve with this pair of cocks is made, this practice method is Although it is possible to control the sub course, there is a disadvantage that it cannot control the height.

In other words, when the serve is high in badminton, the opponent can easily score with an attack such as a push, so height adjustment is more important than the serve course. is not

1 to 8, the sub guide 100 for net sports of the present invention is coupled to the upper end of the net 10 to limit the movement path of the sub sea cock of the sub practicer to a certain width and height. As such, it includes a pair of vertical bars 110 spaced apart from each other and a horizontal bar 120 coupled to be liftable between the pair of vertical bars 110 .

A pair of vertical bars 110 are detachably coupled to the top of the net 10 in a state in which they are spaced apart from each other.

The vertical bar 110 and the horizontal bar 120 may optionally be provided with a hinge 121 in the center, and can be folded in half based on the hinge 121, thereby reducing the volume during storage.

In addition, although not shown, the vertical bar 110 may have a telescopic structure with a variable length.

The tongs 111 are formed under the vertical bar 110 .

The tongs 111 are parts coupled to the net 10 and may have a general clothespin shape as shown in FIG. 2 or a clip shape with elasticity as shown in FIG. 4 .

Specifically, when the tongs 111 have a general shape of clothespins, the first leg may be integrally formed with the vertical part 110 , and the second leg may have a shape coupled to the first leg by a spring.

When the tongs 111 are in the shape of a clip, the lower part of the vertical part is formed in a shape rotated 90 degrees in a clockwise direction, and the lower ends of the open parts are in contact with each other or are disposed close to each other. , When coupled to the net 10, it can be coupled in such a way that the inlet is widened by elasticity by pushing downward.

A through hole 112 may be formed at a lower portion of the vertical bar 110 in a horizontal direction.

This through-hole 112 is a place for the support line 11 provided at the top of the net 10 to be received through, and when the tongs 111 has a clip shape, it does not need to be formed separately because there is an open portion. However, in the case of a clothespin shape, a through hole 112 may be separately formed in a portion (eg, near a spring) where the first leg and the second leg contact each other.

If there is no through hole 112, the vertical bar 110 interferes with the support line 11 when it is coupled to the net 10 and the vertical bar 110 is tilted toward the front or rear of the net 10, so the cock moves. A problem may arise in that the path cannot be properly formed.

For reference, when the vertical bar 110 is coupled to the net 10 , the part where the tongs 111 catches the net 10 is the net portion of the net 10 or the closed portion of the net, and the support line 11 . Silver is inserted through the top of the closure area.

As shown in FIGS. 2 and 5 to 8 , the vertical bar 110 and the horizontal bar 120 , which can be lifted up and lowered together, may be embodied in various ways.

First, the vertical bar 110 and the horizontal bar 120 may be magnetic coupling (see FIG. 2) or Velcro coupling. For example, a metal or female velcro is provided on the vertical bar 110 , and a magnet or male velcro is provided on the horizontal bar 120 , so that the practitioner can move the horizontal bar 120 to a desired position to couple male and female. Here, the metal and the magnet may be provided inside or outside the vertical bar 110 and the horizontal bar 120 .

Second, although not shown, holes are formed at regular intervals in the vertical bar 110 , and protrusions protrude from one side of both ends of the horizontal bar 120 to insert the protrusions into the holes of a desired height.

Third, although not shown, holes are formed at equal intervals in the vertical bar 110 and the horizontal bar 120 , and the hole of the vertical bar 110 and the hole of the horizontal bar 120 are overlapped and fixed with a pin. is also possible

Fourth, a long groove 114 or a long hole 113 may be formed in the vertical bar 110 in the longitudinal direction, and a long groove 114 or a long hole 113 may be formed on one or both inner wall surfaces at regular intervals. 116) can be formed. Here, a locking piece 115 is formed at the entrance of the long groove 114 so that the width of the entrance is smaller than the inner width, and the locking groove 116 is formed in the locking piece 115 . On the other hand, the long groove 114 may be formed on any one of the front, rear, and both sides of the vertical bar 110 , and the long hole 113 may be formed in a shape penetrating the front and rear surfaces of the vertical bar 110 . . Here, the front and rear surfaces represent the surfaces facing the athlete when the vertical bar 110 is coupled to the net 10 .

Stoppers 122 slidably coupled to the long grooves 114 or the long holes 113 of the vertical bar 110 are formed at both ends of the horizontal bar 120 .

The stopper 122 may be formed in an approximately "I" shape, and the vertical part of the "I" shape is fitted in the locking groove 116 and fixed in position. After being elastically contracted and moved, the position may be fixed while returning to its original state in the locking groove 116 . The horizontal portion of the “I” shape functions as a locking portion that prevents the vertical portion from being separated from the outside when the vertical portion is placed in the long groove 114 or the long hole 113 .

However, the above structure is a case in which the long groove 114 or the long hole 113 is formed on the front or rear surface of the vertical bar 110 or penetrates the front and rear surfaces, and the long groove 114 is formed on both sides of the vertical bar 110 . When formed in, the stopper 122 surrounds the front or rear and both sides of the vertical bar 110 and is coupled to the long groove 114 . In this case, the stopper 122 may have a substantially rectangular shape, but may have a shape similar to that in which a portion coupled to the long groove 114 is open.

Fifth, the structure of the vertical bar 110 is the same as that of the fourth, but the long groove 114 is formed in the front or rear surface, and the horizontal bar 120 has a different structure in the stopper portion of the fourth structure.

The stopper 122 has an “I” shape, and a leaf spring 124 is provided at a vertical portion of the “I” shape. Specifically, the vertical portion has a space formed therein, an elastic hole 123 is formed in the center of one side or both sides to communicate with the inner space, and a plate spring 124 in the form of "∧" is accommodated in the inner space. However, the upper part may be exposed to the outside through the elastic hole 123 . The leaf spring 124 is elastically contracted and moved in a narrow movement section, and then returns to its original state in the locking groove 116 so that the horizontal bar 120 is fixed in position.

The sub guide 100 for net sports having such a structure is a horizontal bar 120 according to the level of the sub practitioner in a state where a pair of vertical bars 110 are spaced apart from each other at a desired position on the net 10. Setting the height by adjusting the height has the advantage of being able to easily practice the height of the sub and the path of the sub.

Therefore, if the sub practice is continuously performed using the present invention, the hitting sensation for the moving distance, height, and direction of the cock can be naturally acquired.

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations fall within the scope of the claims of the present invention.
