Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stretch chair that can perform various stretching exercises, flexible exercises, muscle strength strengthening and massage in parallel.
[0002]
[Prior art]
Various auxiliary devices for stretching exercises, flexible exercises, and strengthening muscle strength have been commercially available. For example, a “hanging health device” that stretches the spine, a “running machine” that is a whole body exercise, and a “walk machine”. In addition, there are "various massage devices", "lumbar twist belt", and "Aotake treading tool" that stimulates the acupuncture points on the soles to increase blood circulation. In particular, stretching exercises have the effect of preventing injuries by loosening muscles at the stage of sports preparatory exercises.In recent years, they have been adopted as preparatory exercises in most sports fields. There has also been provided a health correction device that stretches the back without burden (see Patent Document 1).

[Patent Document 1]
Japanese Patent Laid-Open No. 9-591
Stretch exercises are known in a variety of ways, from those that can be done by one person without using an instrument, those that are performed jointly by two people, and those that use the above-mentioned auxiliary instrument. In particular, high effects are often obtained by using auxiliary devices, and therefore the use of these auxiliary devices is recommended. There are also many auxiliary devices that use electric power to obtain a vibration or massage effect.
[0005]
[Problems to be solved by the invention]
However, since the conventional stretching exercise device, strength strengthening device, and various massage devices are individual or small-sized separate dedicated devices, a wide installation space is required to make these devices all available. However, there is a problem that a lot of expenses are required for equipment costs and electricity costs. In addition, depending on the type of special equipment, it is difficult to move the installation location due to its weight, and there are many cases where it is not possible to use it by its own body type, physical strength and age, and gymnastics performed with more momentum May damage muscles, tendons, ligaments, etc., which are soft tissues.
[0006]
Pre-competitive gymnastics before competition, especially stretching exercises are important for sportsmen, and moderate stretching exercises are also important for general people to maintain their health, but there may be no willingness to exercise when fatigued In some cases, it may not be possible to achieve sufficient physical strength, or sufficient effects may not be obtained.
[0007]
Therefore, the present invention solves the above-mentioned problems, and can perform stretching exercises, flexible exercises, massages and strength-strengthening exercises without using separate dedicated instruments, and corresponds to the user's body shape, physical strength, age, etc. The objective is to provide a stretch chair that can be used for many purposes without the need for a large installation place by taking the optimum usage and ensuring high safety by minimizing the exhaustion of physical strength.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is such that a front column is erected on both the left and right sides of the seat back, and a long plate corresponding to the armpit height of the user is provided on a support plate disposed in contact with the front column. The rod body is inserted and supported in the front-rear direction so that the height position can be adjusted, and the rod body extending in the left-right direction near the upper end of the front column is inserted and supported so that the height position can be adjusted, and connected by the front column and the horizontal member An extension portion extending rearward is formed at the upper end portion of the rear strut, and a plurality of rods are inserted and supported in a large number of holes formed in the rear strut and the extension portion so that the position can be adjusted. The basic structure is a stretch chair in which a lower roller, a middle roller above the lower roller, and an upper roller above the middle roller are disposed. Each component uses a wood product.
[0009]
According to such a stretch chair, depending on the user's body shape, physical strength and age, the ankle plantar flexion and the Achilles tendon press stretch, hamstrings, neck, scapula, shoulder, trapezius, ribcage stretch, chest chain Stretch muscles, supraspinatus and other various stretching exercises, flexible exercises, strength strengthening and massage can be performed safely without fatigue.
