At this time, the elastic movement mechanism may be reduced in elasticity due to repeated use, but because it consists of a flexible tube 10 is formed with an air layer therein, the air layer allows the elastic member of the elastic member can be maintained for a long time.

도 3은 본 발명에 따른 신축운동기구에서 연결부재가 구비된 다른 실시예를 도시한 도면이고, 도 4는 본 발명에 따른 신축운동기구에서 가변부재가 구비된 또 다른 실시예를 도시한 도면이며, 도 5는 본 발명에 따른 신축운동기구에서 신축튜브의 다른 실시예를 도시한 도면이다.Figure 3 is a view showing another embodiment provided with a connecting member in the stretching motion mechanism according to the present invention, Figure 4 is a view showing another embodiment provided with a variable member in the stretching motion mechanism according to the present invention. 5 is a view showing another embodiment of the expansion tube in the stretching motion mechanism according to the present invention.

도시된 바와 같이, 신축튜브(10)의 양단에는 각각 연결부재(40)가 결합되는 것이 바람직하다.As shown, it is preferable that the connecting member 40 is coupled to both ends of the flexible tube 10, respectively.

다시 설명하면, 도 2에 도시된 밴드 타입의 신축운동기구보다 착용이 용이하도록 이음부분을 연결시키거나 연결해제할 수 있도록 신축튜브(10)의 양단에 각각 연결부재(40)가 되는 걸림쇠(41)와 걸림고리(43)를 각각 설치한다. 걸림쇠(41)는 비틀림 탄성부재에 의해 일측을 가압하면 개방되어 걸림고리(43)에 삽입되어 걸리거나 빠져나올 수 있도록 형성된다.In other words, the fasteners 41 which are connected to both ends of the expansion tube 10 so as to connect or disconnect the joints so as to be easier to wear than the band type stretching apparatus shown in FIG. ) And hook ring 43 are installed respectively. The catch 41 is opened to press the one side by the torsionally elastic member is inserted into the catch ring 43 is formed to be caught or exit.

걸림고리(43)와 걸림쇠(41)는 전술한 바와 같이 신축튜브(10)의 양단에 탄성부재(20)가 삽입된 후 부착시트부재(30)에 의해 신축튜브(10)에 결합된다.The catch ring 43 and the catch 41 are coupled to the stretch tube 10 by the attachment sheet member 30 after the elastic member 20 is inserted into both ends of the stretch tube 10 as described above.

이에, 사용자는 신축운동기구를 이용하여 운동할 때 걸림쇠(41)를 가압하여 걸림쇠(41)의 일부를 개방시켜 걸림고리(43)에 걸어서 원하는 신체부위에 착용하여 운동할 수 있다.Thus, the user can exercise by wearing the desired body part by pressing the latch 41 to open a part of the latch 41 to the hook ring 43 when exercising using the stretching exercise mechanism.

또한, 상기와 같은 신축운동기구는 도 4에 도시된 바와 같이, 연결부재(40) 대신 가변부재(50)를 채용하여 사용자의 몸에 맞게 신축튜브(10)의 길이를 조절할 수 있다.In addition, as shown in Figure 4, the stretching mechanism as described above, by employing the variable member 50 instead of the connecting member 40 can adjust the length of the stretching tube 10 to fit the user's body.

가변부재(50)는 신축튜브(10)의 일측에는 죔쇠(51)가 구비된 죔쇠스트랩(52) 이 설치되고, 타측에는 죔쇠(51)가 삽입되는 홀(54)이 형성된 홀스트랩(53)이 각각 탄성부재(20)를 매개로 설치되어 부착시트부재(30)에 의해 고정된다.The variable member 50 is provided with a clamp strap 52 having a clamp 51 on one side of the flexible tube 10, and a hole strap 53 having a hole 54 into which the clamp 51 is inserted. These are respectively installed through the elastic member 20 is fixed by the attachment sheet member 30.

이에, 사용자는 신축운동기구를 이용하여 운동할 때 자신의 신체 사이즈에 맞게 죔쇠스트랩(52)이 설치된 죔쇠(51)를 홀스트랩(53)의 홀(54)에 삽입하여 고정할 수 있으므로 죔쇠(51)가 삽입되는 홀(54)의 위치에 따라 신축튜브(10)의 전체 길이를 길게 하거나 짧게 조절할 수 있다.Thus, the user can insert and fasten the fasteners 51 provided with the clamp straps 52 to the holes 54 of the hole straps 53 to fit their body size when exercising using the stretching exercise device. According to the position of the hole 54 into which the 51 is inserted, the entire length of the flexible tube 10 may be lengthened or shortened.

이때, 도면에서는 가변부재(50)가 벨트로 도시되어 있으나, 가변부재(50)는 벨트로 한정하는 것이 아니라 벨크로 등과 같이 그 길이를 조절하여 체결할 수 있는 부재가 사용될 수 있다.At this time, the variable member 50 is shown as a belt in the figure, the variable member 50 is not limited to the belt can be used to fasten by adjusting its length, such as Velcro.

한편, 신축튜브(10)는 도 5에 도시된 바와 같이, 다수의 셀(11) 공간으로 구획되어 형성되는 것이 바람직하다. 신축튜브(10)가 구획되어지면, 하나의 셀(11)로 형성된 공기층보다 그 개수가 많아지므로 각각의 셀(11)에 공기압이 높아져 신축튜브(10)의 탄성이 더 오래 지속될 뿐만 아니라, 사용자가 사용 중에 신축튜브(10)가 손상되더라도 손상부분에 위치된 하나의 셀(11)만이 손상되므로 계속해서 사용할 수 있다.On the other hand, as shown in Figure 5, the flexible tube 10 is preferably formed to be divided into a plurality of cells 11 space. When the expansion tube 10 is partitioned, the number of the air layers formed by one cell 11 is larger, so that the air pressure is increased in each cell 11 and the elasticity of the expansion tube 10 lasts longer, and the user Even if the expansion tube 10 is damaged during use, only one cell 11 positioned at the damaged portion is damaged and can be used continuously.

이하에서는 상술한 바와 같은 신축운동기구의 사용에 대한 실시예를 상세하게 설명한다.Hereinafter, an embodiment of the use of the stretching apparatus as described above will be described in detail.
