[0005]

SUMMARY OF THE INVENTION An object of the present invention is to make the exercise for strengthening the neck easy and to provide as many opportunities for the exercise as one of the prevention and treatment of back pain. Even if it is medically known that strengthening the neck can be effective in lower back pain, people who suffer from lower back pain can exercise easily with their right and left hands, but create opportunities to exercise in a timely manner It's difficult, and for those who have never had back pain, it's bothersome and lazy. Therefore, it is an object of the present invention to make it easier to exercise for strengthening the neck than when using the left and right hands, and to obtain many opportunities.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to increase the strength of the neck, especially for strengthening the strength against lateral forces.

In the case of a personal chair, as shown in FIG. 1, the side wings 2L, 2R extend from right and left ends of the headrest 1 provided at the upper end of the backrest substantially at right angles to the longitudinal direction of the headrest 1. The means to provide is taken. The side wings 2L, 2R have such rigidity that they are not significantly deformed even when they are pushed in the left and right directions by the head. When the head and the side wings are pressed against each other, it is desirable that the rigidity be acceptable up to a slope that does not slip. That is, the rigidity is set to a degree that allows deflection in a range where a static friction coefficient can be obtained.

Next, in the case of a chair for two or more persons, as shown in FIG. 3, from both left and right ends of a headrest 1 provided at the upper end of a backrest, a longitudinal direction of the headrest 1 is shown. , And has a structure and function similar to those provided in parallel for personal use.

Further, in another example of a chair for two or more people, as shown in FIG. 5, when the backrest is also integrated with the headrest 1, it is attached to the headrest portion of the backrest. Means is provided to provide the side wings 2L, 2R at a position corresponding to the height substantially at right angles to the longitudinal direction of the backrest.

From the examples having the above functions, when it is necessary to stay in the same posture for a long time, the strength and strength of the neck is strengthened by using the side wings 2L and 2R of the present invention to prevent and treat back pain. It is useful for.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The main object of the present invention is to prevent and treat low back pain, and to solve the problem, it is intended to obtain results by utilizing the time when a person uses a chair. However, in the present invention, an action based on an individual's will is required, and this action is to be easily performed and to create many opportunities. People spend more time in chairs as they become more mechanized and automated. However, sitting in a chair restricts behavior and increases the time spent in the same posture, which inevitably increases the likelihood of back pain.

Here, an effective use method of the present invention will be described. First, the back column should be seated in a posture that is as straight as possible and the temporal region should not be applied to either side of the left and right side wings 2L, 2R. Press hard enough. 1
The state is maintained for about 0 seconds, and the pressing force is gradually reduced. That is, the pressing force is strong, the force is slightly maintained, and the force is gradually reduced. When this is done, hit the other side of the head against the side wing and exercise in the same way. It is effective to use the left and right palms every day, but when a person sits on a chair and stays in the same posture for a long time, it is often difficult to hold an object on the hand or spread the elbow in the horizontal direction It is difficult to execute.

It is effective to exercise this exercise frequently to train the neck, but it is necessary to keep in mind that holding it for 30 minutes or more in the same posture is not good for preventing and treating back pain. This exercise can be good enough to train your neck, giving you plenty of opportunities to feel good and go on doing it.

Reference numeral 16 denotes a pin hole 16 for supporting a pin 13 for supporting a side wing.

One of the features of the present invention is that the conventional headrest-equipped chair can be easily mounted without any need for modification as described with reference to the above figures. In the case of a chaise lounge without a headrest, the backrest needs to be modified, but the backrest cross and side wing 2L,
The purpose is achieved by performing a modification in which the support leg mounting holes of the support legs 3 holding the 2R are fixed to the bones of the backrest. Therefore, according to the present invention, it is a feature and an advantage that the present invention can be realized at a low cost even for a currently used or finished product, including newly manufactured various chairs.

FIG. 11 shows an example of the structure of the side wing. The side wing strength member 17 is made of iron, aluminum, synthetic resin, or the like. An elastic member 18 is attached to the inner side surface, that is, the side pressing surface. This elastic material has an elastic property similar to that of a palm. With this structure, it is made so that the pain of the pressing surface is reduced when pressing the temporal region. This purpose is achieved by lowering the hardness with silicon rubber or general rubber. Although other drawings are omitted, it is possible to increase the elasticity effect by providing a gap between the head support pad 18 and the side wing support plate, or making the head support pad 18 itself hollow. In general, it is understood that soft materials such as paulownia are practical for wood, and that the purpose can be achieved at low cost by adopting wood, rubbers, or soft synthetic resins.

[0027]

Since the present invention is configured as described above, it has the following effects.

Side wings 2L and 2R are provided on both side ends of the headrest 1, and the upper side of the ears of the temporal portions is pressed against the side wings to strengthen the strength of the neck. In particular, it can be trained against lateral forces that tend to lack exercise.

It is painful to stay in the same posture when traveling long distances using a chair on an airplane, train, bus, or the like, and it is not good for the human body and easily suffers from back pain. Use this time to strengthen your neck. More importantly,
By this exercise, a pleasant feeling can be obtained at the same time as relieving stress in the same posture.

When a person travels a long distance using a vehicle for a long time, he or she sleeps during the day as well as at night. At this time, people often fall asleep and fall down sideways, causing trouble for their neighbors. In such a case, if the side wings 2L and 2R of the present invention are provided, it is possible to travel with a sense of security by entrusting them to the heads.

In the case described above, a concave pillow is prepared,
In some cases, this is applied to the backrest or the headrest portion, and the neck is buried in the concave portion to prevent the laterally falling left and right. According to the present invention, such a pillow for preventing falling becomes unnecessary, and it is possible to avoid the same posture by leaving the body left and right.

When a person is in the same posture during sleep, stress accumulates and the user tries to solve this by turning over. Similarly, if you are in the same position on the chair, stress will accumulate and you will try to change your posture. In this way, exercise is performed to train the neck. If the motivation is to exercise the neck during the process of refreshing the body, mood, etc., the effect is further enhanced.

According to the present invention, the side wings 2L and 2R are attached to the conventional headrest 1, thereby strengthening the strength of the neck, thereby enabling one of the prevention and treatment of low back pain. The economic effect is great because the stress relief and refreshing feeling can be obtained.
