Description

  The present invention relates to a stretch device for relieving or preventing muscle stiffness (hereinafter simply referred to as “stiffness”) such as neck, shoulder, back, and waist.

  People who lack exercise, those who work on computers for a long time, and people who drive a car for a long time are likely to have stiffness on their neck, shoulders, back, waist, and the like. People who have these stiffness symptoms also have an effect on their daily lives, so they are treated through specialists such as rejuvenation and massage. However, in the case of receiving treatment through specialists such as rejuvenation treatment and massage, the treatment costs are high, and it takes time to go to the hospital, so that time constraints in daily life become large.

  For this reason, for example, a stretching device has been proposed for easily relieving and preventing neck stiffness and shoulder stiffness by stretching exercise (see, for example, Patent Document 1).

  In the instrument (health bar) of Patent Document 1, grips having a substantially elliptical cross section are formed on both ends of a rod having a substantially rectangular cross section, and the user grips the grips on both ends of the rod. For example, a stretching exercise is performed by moving the upper body to the left and right, up and down, etc. in a state where both arms holding the grip portion are extended forward.

  Hereinafter, the present invention will be described based on the illustrated embodiments. 1A and 1B are schematic views showing the appearance of the stretch device 1 according to this embodiment, and FIG. 2 shows a horizontal state in which the user makes the stretch device 1 contact both sides on the back side of the neck. It is a front view which shows the state hold | maintained. 1A is a plan view of the stretch device 1, and FIG. 1B is a front view of the stretch device 1. FIG.

  As shown in FIGS. 1 (a) and 1 (b), this pipe-shaped stretch device 1 is composed of an intermediate pipe portion 2 and distal end side pipe portions 3 that extend linearly from both sides of the intermediate pipe portion 2, respectively. Has been. The stretch device 1 is formed of, for example, a stainless steel pipe member, and has a diameter of about 2 to 3 cm and an overall length (length in the left-right direction in FIGS. 1A and 1B) of 140 to 170 cm. Degree.

  The intermediate pipe portion 2 includes a first intermediate pipe portion 2b that is bent so as to open obliquely forward both sides (obliquely lower side in FIG. 1A) from the central curved portion 2a at an angle α1, and a first intermediate pipe portion 2b. There is a second intermediate pipe portion 2d that is bent so as to open obliquely rearward (obliquely upper side in FIG. 1A) at an angle α2 (= angle α1) from the tip portions 2c on both sides. Each front end side pipe part 3 is slightly inclined front side (obliquely lower side in FIG. 1A) with respect to the left and right direction in FIG. 1A from the end parts 2e on both sides of the second intermediate pipe part 2d. Is bent slightly.

  The angle α1 (= angle α2) is about 90 to 130 degrees. Moreover, as shown in FIG.1 (b) and FIG. 2, when this stretch instrument 1 is made into a horizontal state and it sees from the front side, it has become linear form.

  As shown in FIGS. 1 (a), 1 (b), and 2, the front side of the intermediate pipe portion 2 (first intermediate pipe portion 2b) of the stretching device 1 (lower side of FIG. 1 (a)) during stretching exercise. ) The back side of the user's neck C is brought into contact with two places on the surface.

  As shown to Fig.3 (a), each front-end | tip side pipe part 3 can be divided | segmented so that removal is possible by the connection part 3a by the side of the intermediate pipe part 2. FIG. As shown in FIG. 3 (b), a flange 4 having a male threaded portion 4a formed on the inner peripheral surface of one side (distal end pipe portion 3a1) 3a 'of the connecting portion 3a. Are joined by welding. Further, a nut 5 having a female screw portion 5a is joined to the inner peripheral surface of the other side (tip side pipe portion 3a2 on the intermediate pipe portion 2 side) 3a "of the connecting portion 3a by welding.

  Then, by screwing the male screw portion 4a of the tip side pipe portion 3a1 on the side to be removed into the female screw portion 5a of the tip side pipe portion 3a2 on the intermediate pipe portion 2 side, the tip side pipe portion 3 is fixed. They are integrally connected by the connecting portion 3a (see FIG. 1A). Thus, by dividing the distal end side pipe portion 3 by the connecting portion 3a, the overall length of the stretch device 1 can be shortened, so that it can be stored without taking up space when not in use, and is easy to carry.

  Next, an example of stretching exercise using the stretching device 1 will be described with reference to FIGS.

  First, the both sides of the rear part of the user's neck C are brought into contact with the front surface of the first intermediate pipe 2b of the intermediate pipe 2 of the stretch device 1 (see FIG. 2). Then, both arms are widened in the left-right direction and raised slightly above the horizontal so that the vicinity of the wrist is placed lightly on the upper tip side of the tip-side pipe portion 3 from the rear side.

  Then, from the state of FIG. 2, for example, a stretching exercise such as turning (twisting) the upper body in the left-right direction (see FIGS. 4A and 4B), or a stretching exercise such as moving the upper body in the vertical direction of the side surface. (See FIGS. 5 (a) and 5 (b)). Further, a stretching exercise (see FIGS. 6 (a) and 6 (b)) is performed such that the upper body is tilted slightly forward and turned (twisted) in the left-right direction.

  Thus, when performing the stretching exercise as described above using the stretching device 1, the intermediate pipe portion 2 and the distal end side pipe portions 3 of the stretching device 1 are substantially over the upper portions of both shoulders from both sides of the neck portion C. Since it is in a linear contact state, the rear side of the user's neck C is lightly in contact with two locations on the front side surface of the first intermediate pipe portion 2b of the intermediate pipe portion 2. Therefore, the first intermediate pipe portion 2b of the intermediate pipe portion 2 does not come into contact with one point of the rear portion of the neck portion C and is compressed, and pain occurs on both sides of the rear portion of the neck portion and in the vicinity of the rear portion even if stretch exercise is performed for a long time. There is nothing.

  In addition, when performing the stretching exercise as described above using the stretching device 1, the both sides of the rear portion of the user's neck C are positioned on the front side of the first intermediate pipe portion 2b of the intermediate pipe portion 2, so that the stretching device 1 intermediate pipe part 2 and each tip side pipe part 3 are in a state of being in contact with the upper part of both shoulders from both sides of the neck part C in a substantially straight line shape. Thereby, since the center (the central bending part 2a of the intermediate | middle pipe part 2) of the stretch instrument 1 and a user's body axis correspond substantially, a sense of unity increases and it can stretch comfortably.

  Therefore, the muscles around the shoulder, back, and waist can be stretched comfortably, which is effective in the relief and prevention of stiff shoulders and waist stiffness. Furthermore, the two sides of the front side of the first intermediate pipe portion 2b of the intermediate pipe portion 2 are in light contact with the vicinity of both sides of the rear portion of the neck portion, so that the contact with the neck portion at this time has a massage effect that loosens the stiffness. , Neck stiffness can also be reduced.

  In addition, as shown in FIG. 7, a pad member 6 having hygroscopicity and elasticity may be attached to the front surface side of the first intermediate pipe portion 2 b of the intermediate pipe portion 2. The pad member 6 is formed in a curved shape in accordance with the shape of the first intermediate pipe portion 2b that is bent by resin molding, and the first opening portion 6a provided on both sides is passed through the intermediate pipe portion 2 so that the first It can be attached to the front side of the intermediate pipe portion 2b.

  By attaching such a pad member 6 to the front side of the first intermediate pipe portion 2b, the user's neck does not directly contact the metal (stainless steel) first intermediate pipe portion 2b. Therefore, even if sweat is generated from the neck portion during use in summer, the pad member 6 having hygroscopicity absorbs moisture, so that the user can perform stretching exercise without feeling uncomfortable. Further, when used in winter, the coldness of the metal is alleviated by the pad member 6, so that the user can perform stretching exercise without feeling uncomfortable.

  In addition, when the pad member 6 becomes dirty, it can be used in a new state any number of times by removing it from the first intermediate pipe portion 2b and washing it.

  Moreover, in the said embodiment, it was the structure which enabled it to detachably divide each front end side pipe part 3 of the stretch instrument 1 by the connection part 3a by the side of the intermediate pipe part 2, but as shown in FIG. The stretch device 1 may be formed by integrally forming the intermediate pipe portion 2 and the distal end side pipe portions 3.

  Thus, by integrally forming the intermediate pipe portion 2 and the respective distal end side pipe portions 3, manufacturing is facilitated and the number of parts is reduced, so that the cost can be reduced.

  Moreover, in the said embodiment, although each front end side pipe part 3 was bent a little so that it might face the diagonally front side from the both sides 2c of the intermediate | middle pipe part 2, as shown in FIG. 3 may be formed linearly in the left-right direction from both side portions 2c of the intermediate pipe portion 2. In this case, since it is necessary to extend both arms in the left-right direction, it is possible to perform stretching exercise with more load applied from the shoulder to both arms.

  In addition, in the said embodiment, although the intermediate | middle pipe part 2 and the front end side pipe part 3 of the stretch instrument 1 were comprised by the pipe member, you may form similarly with a column-shaped metal member.
