Description

TECHNICAL FIELD The present invention relates to a stretching tool capable of widening the range of motion of shoulders, elbows, scapulae, etc. using centrifugal force.

Conventionally, as tools for assisting exercise of shoulders and arms, a shoulder joint stretching tool described in Patent Document 1 and an exercise aid for arms and shoulders described in Patent Document 2 have been proposed.

The stretch tool of Patent Document 1 is a stretch tool that is composed of a T-shaped rod-shaped member as a whole. By holding this tool with both hands and performing a predetermined motion, the range of motion of the shoulder, elbow, and scapula is expanded and stretched while adjusting the pain and load.

On the other hand, the exercise assisting tool of Patent Document 2 is an assisting tool configured with a conical spiral cushion material. In addition, it is an exercise assisting device that allows the user to turn the arm on which the exercise assisting device is attached from the root while lying sideways or on the back.

Both the stretch tool of Patent Document 1 and the exercise aid of Patent Document 2 have the inconvenience of making it difficult to understand how to use them.

That is, in the T-shaped stretching tool of Patent Document 1, the position of holding the stretching tool is changed, or the exercise method and action are changed each time the usage method such as flexion, extension, external rotation, internal rotation, etc. is selected. There is a need. Therefore, without an instructor, it becomes difficult for users to understand how to use the device according to their own symptoms.

Moreover, since this stretching tool has a rod-like T-shape, there is a possibility that an unexpected situation may occur if the tool comes into contact with the surroundings during use.

On the other hand, the exercise assisting device of Patent Document 2 is used while lying on one's back or sideways. At this time, the user raises and lowers the arm to lightly tap the floor, or stretches the arm sideways to open the chest wide, and furthermore, with the palm facing upward, shortens and extends the arm while stretching the shoulder joint. Various movements are required, such as abduction and adduction. As a result, users find it difficult to understand how to use the device to suit their own symptoms without an instructor.

Furthermore, according to this exercise assisting device, the user is configured to move the arm on which the conical and spiral cushion is attached while lying down. Therefore, this conical cushion restricts the range of motion of the arm, making it difficult to move the arm sufficiently.

Therefore, the present invention was created to solve the above problems, and it is possible to expand the range of motion of the shoulder, elbow, scapula, etc. To provide a stretching tool suitable for self-care by enabling exercise suitable for symptoms of .

The first means of the present invention is a stretching tool that expands the range of motion of the shoulder, elbow, scapula, etc., and includes a gripping body 2 that is gripped by the fingertips in a standing posture, and a finger gripping the gripping body 2 that reaches the floor. The weight 1 is arranged on the tip side of the grip 2 so as not to contact the floor within the range, and the weight of the weight 1 is used to rotate the arm gripping the grip 2. The gripping body 2 is formed of a string-like member, and has a storage part 2A for storing the weight body 1 on the front end side, and a gripping part 2B for hooking fingers to a part on the rear end side extended from the storage part 2A. and a length adjusting portion 2C for adjusting the length of the gripping body 2 at the position of the finger to be hooked on the gripping portion 2B. It is provided continuously with the height adjusting section 2C .

The weight 1 of the second means has an elastic force on at least the surface of the weight 1 so as to absorb the impact when it hits the weight 1, or the weight 1 is made of an elastic material. Alternatively, the weight 1 is formed by filling a powder or granular substance in a bag.

The weight 1 of the third means has a weight of 140 to 180 g per piece, and is constructed so that one or a plurality of weights 1 are used depending on the user.

The weight 1 of the fourth means is formed by injecting a liquid into the inside of a soft tennis ball to have a weight of 140 to 180 g.

According to the present invention, it is possible to perform an intuitive motion such as holding the device with one hand and turning the arm, and stretching exercises that widen the range of motion of the shoulder, elbow, scapula, etc., can be easily performed. In addition, the exercise of rotating the arm using centrifugal force is a simple movement, but it increases the flexibility of the muscles, relieves fatigue and pain comfortably, and restores the physical condition in a few minutes.

Moreover, since the user can easily exercise according to his/her own physical condition and symptoms, it is possible to exercise effectively and suitable for the user himself/herself without the need of an instructor, making it an optimal tool for self-care.

In addition, the weight 1 has an elastic force on at least the surface of the weight 1 so as to absorb the impact when it hits the weight 1, or the weight 1 is made of an elastic material. Alternatively, the weight 1 can be safely used by filling a bag with a powder or granular material.

Furthermore, the weight 1 has a weight of 140 to 180 g per piece, and one or a plurality of weights can be arranged on the grip 2 depending on the user, so that it can be adjusted to individual differences regardless of age or sex. It can be used effectively as a stretching tool.

By injecting a liquid into the inside of the soft tennis ball to form the weight 1 with a weight of 140 to 180 g, it has a safe elastic force and excellent durability even when it hits the body, so it can be used continuously for a long time. becomes possible to use.

Also, when the body is hit with the ball-shaped weight 1 into which the liquid is injected, the vibration transmitted from the skin promotes the flow of blood and lymph, which has the effect of loosening the joints and muscles. Therefore, in addition to the exercise of rotating the arm, the exercise of rhythmically striking each part of the body with the weight 1 is also possible.

According to the grip 2 of the present invention, the grip 2 has a very simple structure, and the user can intuitively understand how to use it visually. Moreover, the length adjuster 2C allows the user to easily change the length of the gripper 2 according to the physique and exercise of the user.

Thus, according to the present invention, it is possible to widen the range of motion of the shoulder, elbow, scapula, etc., with an extremely easy-to-understand action such as holding the patient with one hand and turning the arm, and furthermore, exercise suitable for one's own physical condition and symptoms. It achieved its original goal of becoming the best tool for self-care.

FIG. 4 is a perspective view showing a state in which the weight body of the present invention is put into the gripper; FIG. 4 is a perspective view showing a state in which the number of weights of the present invention is increased; It is a rear view showing another example of use of the present invention.

INDUSTRIAL APPLICABILITY The present invention is a stretching tool that mainly uses centrifugal force to widen the range of motion of shoulders, elbows, scapulae, and the like.

That is, the tool of the present invention comprises a weight 1 and a gripper 2, and uses the weight of the weight 1 to rotate an arm gripping the gripper 2 (see FIG. 1).

The gripping body 2 is a member to be gripped by the fingertips in a standing posture, and the weight body 1 is arranged on the tip side of the gripping body 2 so as not to contact the floor within the range from the finger gripping the gripping body 2 to the floor. there is

The weight 1 is formed with a weight of 140-180g. This weight has the effect of giving an appropriate centrifugal force when turning the arm (see FIG. 2). That is, although the direct load applied to the arm and shoulder is small, centrifugal force acts to extend the arm when the arm is rotated (see FIG. 1). Therefore, by rotating the arm while extending the arm, the user can gradually widen the range of motion of the shoulder, elbow, scapula, and the like.

In addition, since there are individual differences in shoulder and elbow muscles, one or more of them are used depending on the user. For example, normal use uses one weight 1 (see FIG. 2). In addition, depending on the person's physical strength and symptoms, add 2 to 3 to increase the centrifugal force (see Fig. 4).

The material constituting the weight 1 can be selected from various elastic materials such as various rubber materials and elastic plastic materials. Alternatively, the surface of the weight 1 may have an elastic force so as to absorb the impact when it hits the weight 1 . For example, it is possible to adopt a configuration in which the circumference of the weight body 1 made of a non-elastic material is covered with an arbitrary elastic material. Furthermore, it is also possible to use a powdery or granular material for the weight 1, such as forming the weight 1 by filling a bag with sand, adzuki beans, or the like.

Furthermore, the shape of the weight 1 is not limited to the spherical shape shown in the figure, but may be any shape, such as a block shape such as a rectangle or a star, or the shape of the weight 1 may be formed using a fine elastic material. do not have.

The illustrated weight 1 is formed by injecting a liquid such as water into a soft tennis ball (see FIG. 3). That is, the mass 1 is formed by injecting water instead of the air that is normally injected. This soft tennis ball has weight 1 with a weight of about 160 g and a diameter of 6.6 cm.

Thus, the weight 1 formed by injecting a liquid such as water into a soft tennis ball has the same property of bouncing when dropped. Therefore, the weight 1 has sufficient elasticity, high durability, and moderate weight.

Therefore, the ball-shaped weight 1 can be used not only for using centrifugal force but also for hitting various parts of the body during massage (see FIG. 5).

The gripping body 2 includes a storage portion 2A for storing the weight 1 and a gripping portion 2B for hooking fingers (see FIG. 2).

The storage portion 2A shown in the figure has a bag-like shape made of pile fabric, and is constructed so that the weight 1 can be easily stored in the storage portion 2A through an expanding and contracting opening 2Aa (see FIG. 3).

On the other hand, the gripping portion 2B is a portion extended from the storage portion 2A, and is provided with a length adjusting portion 2C for adjusting the length of the gripping body 2 at the position of the finger hooked on the gripping portion 2B (see FIG. 2).

The grip portion 2B shown in the figure is formed in two strips of pile fabric extended from the storage portion 2A (see FIG. 3). Further, the gripping portion 2B is tied at a plurality of locations along the longitudinal direction to form a length adjusting portion 2C. The user adjusts the length of the gripper 2 by selecting the position of the length adjusting portion 2C and placing his/her fingers thereon (see FIG. 2).

Also, the material of the gripper 2 is not limited to the examples. For example, in addition to using a flexible plastic material, it is also possible to use various string materials and chains. Therefore, it is also possible to change the material of the storage portion 2A and the grip portion 2B. In addition, any shape can be selected for the gripping body 2 as long as it is a shape that allows the arm to be rotated using the weight of the weight 1 .

According to the usage of the present invention, by rotating the arm that grips the gripper 2, the weight of the weight 1 is used to perform an exercise that expands the range of motion of the shoulder, elbow, scapula, etc. (Fig. 1 reference). That is, since these ranges of motion vary greatly from person to person, the user rotates the arm as much as possible. At that time, the load of the weight 1 is added by centrifugal force, so that the stretching exercise is suitable for the user.

At this time, the user selects the length adjusting portion 2C and hooks the fingers on the grip portion 2B to hold the grip 2 so as not to come off from the fingers during rotation (see FIG. 2). For example, hook two fingers, the index finger and the middle finger, on one of the three length adjustment parts 2C, relax the shoulders and elbows, let the centrifugal force take over, and slowly move the arms forward 10 times and backwards. The basic exercise is to rotate about 10 times. It is preferable to continue this basic exercise two to three times a day for several weeks. However, the exercise time, the number of rotations of the arm, and the rotation speed should be determined by the individual.

Also, a person who feels that the weight of the weight 1 is insufficient adds a plurality of weights 1 to use. According to experiments, it was appropriate to add up to 2 to 3 weights 1 weighing 140 to 180 g.

Furthermore, in an experiment, after providing samples to 150 people and continuing to exercise for several weeks, it was found that almost all of them felt improvement in shoulder and elbow pain points, although there was a difference in degree.

Furthermore, the weight 1 formed by injecting a liquid into a soft tennis ball can be used as the weight 1 for hitting various parts of the body during massage. That is, by using the length of the grasping body 2, the back, waist, or the like can be hit with the weight 1 to promote blood circulation (see FIG. 5). At this time, a more comfortable massage becomes possible by continuing rhythmically by utilizing the recoil of the weight 1 when hitting the body.

It should be noted that each configuration shown in the drawings is merely an embodiment of the present invention, and the overall shape, structure, material, etc. of the weight 1 and gripper 2 may be freely changed within the scope of the present invention. It is possible.
