Description

Stretching apparatus of massage mat

The present invention relates to a stretching device for a massage mat, and more particularly, to a device for stretching the cervical, thoracic, and lumbar regions by massaging the human back muscles using a massage roller when a user is on the massage mat. It is about a stretching device of a massage mat that prevents wear and noise by using a driving linkage in which an LM guide and a timing belt are combined for movement, and secures the vertical movement of the massage roller itself through a guide groove.

Recently, there is an electric mat that uses a heating wire, and in addition to a hot water mat function that circulates hot water to heat the inside, a massage mat function is added to massage the muscles by pressure or ultrasound.

Massage can cause a biological reaction by directly applying a mechanical stimulus to the skin in a certain way, mainly using the hands, so that the body's modulation can be corrected to cure diseases and improve health.

When a part of the body is massaged, it promotes circulation of blood or lymph, boosts metabolism, increases tissue nutrition, excretes waste, and enhances resistance. Because it works, it can promote the recovery of paralyzed nerves with a physical therapeutic effect and correct changes in bodily functions.

Looking at the structure of the mat having a massage or massage function, since it performs a massage or massage function while being tapped or rolled, the corresponding devices are provided in the mat.

The heating mat disclosed in Korean Patent Registration No. 10-1832281 is a heating mat equipped with a rolling massage function. When the massage device stops working, the massage roller is positioned under the horizontal cover to maintain a flat state without protruding parts. This is the provided heating mat.

However, the massage device used in the prior art has severe vibration or vibration according to the operation of the timing belt, thereby causing wear on the motor shaft for driving the timing belt, and thus frequently malfunctions.
