Description

Back massage device {back massage device}

The present invention relates to a back massage device, and more specifically, it is simply installed on the back of a floor or a chair or sofa to selectively or comprehensively massage the neck, shoulders, back, waist, and buttocks while the user naturally leans or lies on the upper body. It relates to a waist massage device invented to allow massage and massage to be performed to relax tense muscles in the corresponding area and at the same time to allow blood to circulate smoothly, as well as to significantly improve joint functions.

Due to complex social life, modern people accumulate mental or physical fatigue, and blood circulation is not smooth due to this. Stress was increasing, and these knotted muscles were released by hand kneading or massaging.

However, in order to release the knotted muscles using the hands, it is necessary to massage and massage the knotted muscles with strong force for a long time, so the action itself is not easy, and the continuous muscle massage causes the hand muscles to stick together.

In order to solve this problem, massage or massage devices having a built-in massage element including a solenoid drive method, a mechanical operation method by motor drive, and a low frequency operation method have been developed and proposed.

Among these, the most widely used massage device is usually a vibrator having a plurality of massage protrusions, that is, a vibrator, which is placed in a state in consideration of the body's meridians and meridians, and when power is applied, the massage protrusions are minute and quick. It is configured to release or relax the knotted muscles by stimulating the body surface while appearing and descending, thereby recovering from physical or mental fatigue.

In addition, among the above-mentioned massage devices, massage devices that can be expected to have an effect include expensive massage devices in the form of chairs, massage devices in the form of waist cushions or cushions, and massage devices in the form of beds, with various structures and shapes. In addition, a hand massager or a hand massager is widely used as a type that is held in the hand and used.

However, conventional massage machines or massage devices, such as massage chairs, massage beds, and massage cushions, have the feature that massage of the back or waist is performed without difficulty, but due to the structure of the massage machine or massage device, the back of the neck (especially both sides of the back neck) or the shoulder , and arm massage has a structure that cannot be achieved.

Accordingly, it is not an exaggeration to say that the massage of the neck, shoulder, arm, etc., which is the part that requires the most massage in the actual human body, is only a half massager that cannot be expected at all.

In addition, the massage chair or massage bed among the conventional massage devices or massage machines has a fairly large volume and excessive weight, so it is difficult to carry and install frequently according to the user's needs, and in the case of a massage cushion, it is difficult to carry or transport Although there is a side that is made quite freely, it is also bulky and its use is extremely limited.

In other words, most of the various massage machines or massage devices, including the conventional massage chairs, massage beds, massage cushions, etc., are bulky, have a fairly high price range, and have the inconvenience of being mobile or portable. There was a problem of extremely limited use because massage for body parts such as the back of the neck, shoulders, and arms, which are the most fatigued parts of the human body, could not be performed at all.

On the other hand, recently, there are many people complaining of turtle neck due to excessive use of portable terminals including mobile phones, regardless of gender and age. Since the waist line is also distorted along the circumference, there is a need for a massage device that can prevent or easily correct this.
